[Q] LG L3 e400 stock recovery, rooting, Link2SD, etc. - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

Hi everybody,
my sister has got this phone a month ago and she is obviously out of memory. So the most immediate step is to install Link2SD. I am used to my Galaxy phone where to root it one just needs to hold Vol UP+Home+Power to get into the stock recovery and install any zip files. So after founding nothing useful in Internet I decided to ask in here:
- Is there any similar "hotkey" for the e400 to boot in stock recovery?
- Can the stock recovery install any zip file?
- Does the 1click rooting for Galaxy phones really works? If so I can make a simple zip package with "su" only, she would get mad dealing with notifications and all crap like that (I know, it would be more insecure but we just give permissions all times, anyway don't we? )
- Would it break the official updates? I know that the rooting would be lost after updating, but it would be a matter of seconds to redo it if it works like above.
- Any idea about a custom kernel (better if the latest stock one with modified scripts in RAM disk) with support for /etc/init.d? I could port my script Switch2SD which operates like Link2SD but at boot time.
- Last but not least, why the heck the SD card has two FAT partitions?!? What's the point for Android to show the first SD partition as "internal memory" if it doesn't really use it? Well, it does, but with App2SD which is lame.
I am not really interested on CWM or Custom ROMs unless they are really needed. Thanks in advance for any help!!

First, the L3 doesn't have a stock recovery, the key combo only do a full wipe;
Second, use SuperOneClick to root the L3, it works very well;
Third, Rooting your device doesn't break the official updates (if there will be any);
Fourth, I am working on a kernel that supports init.d, and I don't know about any stock kernels with init.d (only overclock);
And at last, I don't know why we have two FAT partitions, but I know that we can merge these partitions with SDMergE400.
Hope I helped!

Thank you very much, very kind from you! But that introduces a new question: how can I install SuperOneClick if I can't get into the stock recovery?
EDIT: never mind, I thought it was the .zip for the root installation for the Galaxy phones..
Then will your kernel be ready soon? Will it be a stock one?

Well, I am modding the kernel on the SDMergE400 zip, just testing, then I will mod the Stock kernel!
But these are just plans, it will take a little time...

Never mind, I managed to root the phone (with spectrum_root_linux_osx from OS X. It works!!) and I installed Link2SD. I must say that this phone seems amazingly fast! I have a Galaxy Pop Plus (it's equivalent to the Galaxy Y) and its performances are horrible. The LG e400 is a nightmare in terms of system administration, though. With our phone we can do everything from stock recovery.So I better leave it as it is. Hopefully Link2SD won't mess up. My sister seems confident enough with it now. But if it breaks it will pain a customer support pain (you know, sisters.. ).

If you don't feel good to mess up with your phone, you better leave it as it is, like you said!
Android isn't for the users who want everything simple and ready, we have to think a little when using it (and that's why there are much people with iPhones and stuff)

Sure. That would be true for me as well If only I wasn't the developer of the custom and stock modified (with /etc/init.d support) kernels for my Galaxy S5570I phone..
What I meant is that the way the filesystems/Partitions are organized in the LG e400 is totally different from everything I have seen before. For example I made now 3 partitions in the SD card for Link2SD with the first one of 20MB. Android still reports a first partition of 1GB. It's just that I don't have time to mess up with it, being my sister's phone. So i decided to leave it rooted with Link2SD and that's it. I checked SDMergE400 as well, but they talk about installing a CM 9 to make it working. I could do it if the phone was mine, but not with someone else phone. regarding my phone, it sucks. badly. Ask anyone with a Galaxy Y, which uses the same CPU BCM21553. We don't even have the source codes to make full use of the GPU Videocore IV and thus to port the CM. In Antutu benchmark the soldiers go at 10-14 fps.
The iPhone (iOS) has mods as well, anyway. People are doing some pretty neat stuff after jailbraking it. Which is not even needed to run some basic useful tools like Adblock, unlike Android that needs to be rooted.

Oh yes, filesystems on the L3 are REAL messy :/
But I got a chinese tablet (SK-3031 or GT-1230) and it's really, really complex to work in it's filesystems, so it's easy for me ;D
And Android have some neat features by default that the iDevices don't (freedom, for example) :laugh:

Eris Dual Boot ROM

I'm posting this in General as I don't have the knowledge to port this or develop a similar version for the Slide and I don't want to clutter up the Development forum.
Team ADX over in the Droid Eris forum came up with this gem; a dual boot Eclair Sense/2.2 AOSP ROM. http://forum.xda-developers.com/showthread.php?t=824072
I don't know if this can be done on our phones, but I thought it possible as you don't need to flash a custom recovery.
man this would awesome... the best of both worlds, run and "stock" ROM so we can still receive updates and still have CM.
i was actually thinking about dual boot just the other day! i dont feel like id be switching back and forth from 2 roms but itd be a great feature for those who do. unfortunately i dont think we have that much developers :/
I was reading the instructions for it and it looks like we'll have to wait for S-OFF before we can try it.
Part of the scripting is telling the phone how to partition the phone, sizes of those partitions, and so on. The slide is, generally speaking, un-brickable and it's the measures used to give us that luxury that also prevent us from doing so much like R/W on the system while in a non-recovery boot and changes we do make while booted are just wiped on reboot *sigh* man I love that ramdisk image.
Once we get S-OFF let's get this project started

I don't think S-OFF is the issue. The partitioning instructions only refer to sdcard. This command:
Code:
mkpartfs primary fat32 0 3500 (can be adjusted to your needs. This partition will be used by the 2.1 rom and by recovery)
I think is only for the phone ROM storage and the for the recovery to find the boot scripts. According to the instructions, they're only partitioning the sdcard to run the AOSP ROM in it. They install the 2.1 Sense ROM to the phone, get it set up, run the boottosd script to boot into the 2.2 AOSP ROM on the sdcard, then set that up and run the boottophone script to go back to 2.1 Sense. They're running a ROM on the sdcard!
As I said before, I think something like this can work for our phones because it doesn't require flashing a recovery. The problem is we don't have the devs to do it.

You won't be able to do a simple port. I posted about it more of as a proof of concept. Take the same idea, but obviously using our espresso sense and CM6.

Ok that makes sense. I thought it was pointing to the partitions on the phone telling it to format to a different size for some reason. Then what's preventing us from doing this? Just a lack of a proper script?
I have not poked around with how they are going about doing everything, but I was the one who got the ball rolling with my dual boot linux script. Conap took the basic setup and made some changes to just install them both on the phone and sdcard. Here is the basic of what it is doing....
The init.rc file found in boot.img has been modified for the froyo rom on the sdcard. The lines where it mounts [email protected] , [email protected], and [email protected] have been changed to the partitions on the sdcard (/dev/block/mcblk0px) The updater-script for froyo has been modified to flash the rom to the partitions on the sdcard. There are some gscripts which are ran from the phone that either modify or replace the boot.img for the rom you want to boot into.
The froyo ROM is running completely off the sdcard and the recovery is left untouched. The script that is required if you are using clockworks is because clockworks sbin and folder locations are setup a little different. I was running into some problems with froyo not recognizing the sdcard after making more than 4 partitions. Several had reported to me that their phones also did not recognize the sdcard, but the Eris phones somehow still did. I am working on something that should run from all android phones and allow you the option of installing whatever ROM you want.
One Last Thing..
Anyone is capable of learning how to do some development work. It just takes some patience and "Google". I had no knowledge of linux or any other scripting languages, except windows batch scripts, until 3 months ago.
There is not much activity on my thread, but once I get a working version finished it will be posted there-----Dual Boot Android
When you get it done and own working, post it in development. I only posted the thread in general because I knew I wasn't going to be the one to develop it. I'm a welder by trade and java and linux are a little beyond me. Although I am trying as I'm using Ubuntu as my main OS and starting reading java tutorials.

If there was ever a reason to get a dev started on a project, this would be it. I would reconsider upgrading from the Slide if we had something this awesome.

From what I understand, android can not *see* more than 4 partitions so they had to do something a bit different. Somewhere in the thread that's linked it states what they did to get it to work.

The "companies" wanted s-off due to the large number of brix getting returned for handest exchange and assurion claims, just to figure out somebody pooched sumthin up trying to be a HAXOR, if you haven't done anything like this before. Id suggest peeps get a g1 or some other root & rom-o-matic type for and play with it till you take on your brand new handset trying to install some bleenin edge hack...
You gotta learn to wank off before you can try it with somebody else in the room.
I remember my early days at xda, hacking my mda, xcaliber, and esato hacking SonyEricsson fones before they jumped the shark. People who had the ability to read and follow directions (emphasis on the read part) would study till they were sure they would still have a working fone at the end. Hung out and did great stuff with there handsets. And the noobs were wary enough to investigate before they just started mucking about.
So the handset manu. Had to do sumthin and now we have s-off.
the moral of my high and mighty rant an rave, if you don't know how to do sumthing or if you understand what to do but not the why, then keep reading, read more do less

In the newest builds they have 2.1 system on the phones system partition and froyo system on the phones data partition. The data is moved to the SD. 2.1 and previous Rome had no problem with extra partitions on the sdcard.froyo changed the way it mounts the sdcard and could only see 4.
I am actually releasing a dual boot method very shortly that should work on any android phone with very little setup required on your part. I am in the process of finalizing it. Anyone interested in testing please let me know as I want to test on as many devices ad possible

[REF] Nexus S ROM&Kernel Survival Guide

Introduction:
Please read and try to do some research instead of bombarding the developers with the same questions over and over, cluttering the threads with useless and recursive information. I will try to include terms for all the ROMs and Kernels in the Development Section, and remove the obvious things as much as possible. That doesn’t mean it will be perfect! I hope this will be useful for beginners, because it provides most of the basic information you need to get started. From now on, it’s up to you what you do.
I am fully aware that the information included here is for one time use, enough to get you started. Some of these things ARE well known by many of you, but they are still useful for others that are just beginning to learn about their NS. Besides definitions and explanations, I’ll also link to useful posts around xda and other sites, which provide further information on the respective subject.

Stock ROM
Official releases from Google. The reasons most people here flash a stock ROM are: they want to update/ are bored of custom ROMs/ want to start over with their phone/ warranty reasons.
If you want to go back to stock for some reason, check this thread and read carefully, so you get the correct version for you.

Once we decide for a type or ROM (except stock), we head over to the ROMs thread and begin reading the list of features. Now would be a good time to PANIC! No, no, just kidding Those words do exist in some kind of language (not necessarily English). So here’s a very basic list of the most common terms found in our ROM threads:
Code:
[B]AOSP[/B]
[quote]Short for [url=http://source.android.com/]Android Open Source Project[/url]. Its purpose is to maintain the development
of the Android platform. Anyone can use the Android source code for
any purpose, and this is when custom ROMs come in. The [AOSP]
tag is used here to signal a ROM built from Google’s source, a pure
ROM, free of bloatware, with very good performance (generally)
and a very extended degree of customization. [/quote]
[B]Build.prop[/B]
[quote]This file is located in /system/build.prop. It holds the majority
of the runtime flags that are used when Android boots. Basically, it
lists specific information about your device, for applications to use.
You can also edit lines, with a file manager that has access to
/system, in order to change LCD density, build number, device
model and many more. [/quote]
[B]Busybox(ed)[/B]
[quote]Busybox is a collection of simple, but powerful Linux
utilities, that Android doesn't come with by default. It is used
by applications like MetaMorph and Titanium backup in order
to do special operations. You can manage ther version installed
on your phone with various apps from the [url=https://market.android.com/search?q=busybox&c=apps]market[/url] [/quote]
[B]/boot partition[/B]
[quote]This partition includes the bootloader and kernel, and
it enables the phone to boot. Wiping it must be done only if
requested, and the phone must not be rebooted after this operation.
Instalation of a new one is done by flashing a ROM that includes
the /boot partition. [/quote]
[B]/cache partition[/B]
[quote]Inside this partition, Android stores frequently accessed
data and app components. Performing a wipe of the /cache does
not affect personal settings or files, but simply gets rid of existing
data there, which gets automatically rebuilt in time. [/quote]
[B]Dalvik cache[/B]
[quote]Dalvik cache collects the information about the installed
applications and frameworks, and organizes them into a writeable
cache. Under this writeable cache, it stores the “optimized”
bytecode of the applications which is used by the applications
themselves later for a smoother operation. This dalvik cache can
grow as more applications are installed on your phone. It is safe
to wipe dalvik-cache. It will be rebuilt again when the phone
boots. This also explains why your phone takes ages to start up
for the first time. [/quote]
[B]/data partition[/B]
[quote]Also called userdata, the data partition contains the user’s
data – this is where your contacts, messages, settings and apps
that you have installed go. Wiping this partition essentially performs
a factory reset on your device, restoring it to the way it was
when you first booted it, or the way it was after the last official
or custom ROM installation. When you perform a wipe data/factory
reset from recovery, it is this partition that you are wiping. [/quote]
[B]Deodex(ed)[/B]
[quote]In Android file system, applications come in packages with
the extension .apk. These application packages, or APKs contain
certain .odex files whose supposed function is to save space.
These ‘odex’ files are actually collections of parts of an application
that are optimized before booting. Doing so speeds up the boot
process, as it preloads part of an application. Deodexing is basically
repackaging of these APKs in a certain way, such that they are
reassembled into classes.dex files. By doing that, all pieces of an
application package are put together back in one place, thus
eliminating the worry of a modified APK conflicting with some
separate odexed parts. The advantage of deodexing is in modification possibilities. On the other hand, since the .odex files were supposed
to quickly build the dalvik cache, removing them would mean
longer initial boot times. However, this is true only for the first
ever boot after deodexing, since the cache would still get built
over time as applications are used. [/quote]
[B]EFS folder[/B]
[quote]This is a VERY important folder. It contains phone-specific
information, like IMEI (encrypted in the nv_data.bin), wireless
devices MAC addresses, product code (also in the nv_data.bin)
and more. I advise you to make a backup of this folder, and keep
it safe. Remember, backup BEFORE flashing anything. Use [url=http://forum.xda-developers.com/showthread.php?t=1138873]this tool from forum member Borky_16[/url]. [/quote]
[B]Init.d[/B]
[quote]Init.d is very useful because it runs scripts that you can
just delete or replace in the /system/etc/init.d folder. The scripts
are also very flexible and can be used to call other scripts or set
a variety of system settings. [/quote]
[B]G-apps/Gapps[/B]
[quote]A long time ago, in a galaxy far far away, there was a
developer. And he used the Force for developing something called
CyanogenMod. For the happiness of the other folks in the galaxy,
he included some applications from Google. But the Emperor…
oh, sorry… But Google didn’t agree with him including these
proprietary apps, so they sent him a cease and desist letter.
Long story short, the Google Applications are provided separately
via a flashable .zip file. This is the case for pure AOSP ROMs,
and theoretically this is how it should be done. Theoretically. [/quote]
[B]Host File[/B]
[quote]Located in the /etc/ folder, it is used to block ads.
Most ROMs come with a “blocks ~95% of ads” statement. You
can also manage it with apps from the [url=https://market.android.com/search?q=ad+block&c=apps]market[/url]. [/quote]
[B]Logcat[/B]
[quote]The Android logging system provides a mechanism for
collecting and viewing system debug output. Logs from various
applications and portions of the system are collected in a series
of circular buffers, which then can be viewed and filtered by
the logcat command. You can use logcat from an ADB shell to view
the log messages.[/quote]
[B]NANDroid[/B]
[quote]When you take NANDroid backup, it means you are
backing up entire ROM. It’s basically a picture of the ROMs’
state . So when something goes wrong, you have the
chance to restore your phone to the backup state using the NANDroid. [/quote]
[B]NSTools[/B]
[quote]An essential tool that manages tweaks like BLN,
BLD, BLX, Liveoc, OC, CPU Governor, Deep idle and so on.
Written by arifhn, available in the [url=https://market.android.com/details?id=mobi.cyann.nstools&feature=search_result#?t=W251bGwsMSwyLDEsIm1vYmkuY3lhbm4ubnN0b29scyJd]market[/url] and on [url=http://forum.xda-developers.com/showthread.php?t=1333696]xda[/url],
this is a must have application for managing these various options. [/quote]
[B]Odex[/B]
[quote]These ‘odex’ files are actually collections of parts
of an application that are optimized before booting. Also explained at deodex(ed). [/quote]
[B]Power Menu[/B]
[quote]A multiple choice menu that appears when long pressing
the power button. In stock, these are critical options,
such as powering down the device. Developers have also
added options for taking snapshots,
rebooting normally/into bootloader/into recovery and so on. [/quote]
[B]Radio[/B]
[quote]The radio controls basic low-level functions like
network connectivity, Wi-Fi, and GPS. It comes as a radio.img file,
and generally, developers try to leave this out of their
ROMs because different areas require different radios. Pay attention
to this when choosing to flash a new ROM. There is a reference
thread with all the radios [url=http://forum.xda-developers.com/showthread.php?t=1116884]HERE[/url]. [/quote]
[B]Ramdisk[/B]
[quote]Ramdisk.img is a small partition image that is mounted
read-only by the kernel at boot time. It only contains /init
and a few config files. It is used to start init, which will
mount the rest of the system images properly and run the
init procedure. A Ramdisk is a standard Linux feature. [/quote]
[B]Recovery[/B]
[quote]Recovery mode in Android provides an environment for
users to wipe cache, data, factory reset the phone or update
it with a .zip file. There are custom recoveries like [url=http://www.clockworkmod.com/rommanager]ClockworkMod[/url] or [url=http://forum.xda-developers.com/showthread.php?t=1399565]TWRP[/url], which provide additional functionality,
and are very popular for this reason. [/quote]
[B]RTL[/B]
[quote]Short for Right-to-Left and refers to support for languages requiring this type of writing. [/quote]
[B]SetCPU[/B]
[quote]An application built by coolbho3000, which allows CPU speed tweaking and management, allows overclocking, and sets CPU governors. Available on [url=http://forum.xda-developers.com/showthread.php?t=505419]xda[/url] and the [url=https://market.android.com/details?id=com.mhuang.overclocking&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5taHVhbmcub3ZlcmNsb2NraW5nIl0.]market[/url] (try to buy from the market if you want to support his work). [/quote]
[B]SIM Toolkit (STK)[/B]
[quote]Now if you live in the States, you might not even know what
the STK is, so a bit of explaining is in order. Put simply, the STK
allows carriers to load a simple set of menus and 'applications' on
your SIM card. Earlier versions of Android, up to 1.6, actually
included a rather rough, but functional Sim Toolkit application, but
at some point it was dropped. [/quote]
[B]/system Partition[/B]
[quote]This partition basically contains the entire operating system,
except the kernel and the bootloader. This includes the Android
user interface as well as all the system applications that come
pre-installed on the device. Wiping this partition will remove Android
from the device without rendering it unbootable, and you will
still be able to put the phone into recovery or bootloader mode
to install a new ROM. [/quote]
[B]Unsecured Boot.img[/B]
[quote]Used for adb remount, gets you root by default on a shell. (ro.secure=0) [/quote]
[B]V6 Supercharger Script[/B]
[quote]A more technical explanation could be done here, but
the bottom line is that this is used to make your phone run
faster, by better management of memory. [/quote]
[B]Zipaling[/B]
[quote]Zipalign is an archive alignment tool introduced first
time with 1.6 Android SDK (software development kit). It
optimizes the way an Android application package (APK) is
packaged. Doing so enables the Android operating system to
interact with the application more efficiently, and hence has
the potential to make the application and overall the whole
system much faster. Execution time is minimized for zipaligned
applications, resulting is lesser amount of RAM consumption
when running the APK. [/quote]
Kernels​
(Kernel: provides the most basic level of control over all of the phone's hardware; consider them a link between the hardware components and the ROM)
With kernels it’s a little bit easier. At least this is how it may seem. Right after rooting the device, many choose to first flash a kernel (including me) mostly because it gives the opportunity to flash something while not modifying the appearance of the phone. Furthermore, it gives you the ability to change things like CPU clock speed, internal and ARM voltages, and also have different patches and mods designed to prolong battery life/improve speed/provide stability.
Kernels are abundant for the NS, so I’ll be naming the most popular:
GLaDOS
ICUP Kernel Edition
*Matr1x*
SG-NS-ICS - 14-01-2012 - 11UV|Voodoo|BFQ|BIGMEM|BLN|BLD|BLX|TW|Lazy|3.0.15
Netarchy Nexus
NS+4G Trinity (E)UV and OC CM9 + m(any) roms

Many users ask around about which could be the best kernel. For this, xda member bedalus decided to set up a thread where he benchmarked ICS kernels (accurately enough). This should give you an idea where to start from.
Also, there are terms which appear frequently in the features list of kernels, so here’s a very basic list of the most common terms found in our kernel threads:
Code:
[B]BFS[/B]
[quote]A Brain F**ked Scheduler will perform better on CPU intensive
process, which usually cause them to get higher benchmark scores.
However because it only dedicates minimal CPU to background
processes you may experience lag when switching quickly between
different tasks. [/quote]
[B]BLD[/B]
[quote]Backlight Dimmer provides an option for the lights of the
touchkeys to be turned off after a certain period. This can be
tweaked from NStools. [/quote]
[B]BLN[/B]
[quote]Backlight Notification is a mod developed by neldar,
which converts the touchkey backlights into a notification led. [/quote]
[B]BLX[/B]
[quote]Battery Life eXtender, from Ezekeel, manages the maximum
percentage to which the battery is being charged. By default,
the Nexus S is charged to about 95% capacity. [/quote]
[B]CFS[/B]
[quote]A Completely Fair Scheduler is more suited for multitasking.
You may notice performance issues when using CPU heavy
activities like HD games because it is trying to keep the other
processes in the background equal to the one that is hogging the
CPU. It should also be noted that, as designed, this type of
kernel should handle going from listening to music to sending a
text to surfing the web with minimal lag. [/quote]
[B]Deep IDLE[/B]
[quote]Another mod by Ezekeel, which allows the phone to
enter a “deep idle” state while performing tasks when the screen is
off. For example, listening to music with the screen off and
Deep Idle turned on, you should get better battery life than
without Deep Idle. [/quote]
[B]Governors [/B]
[quote]There is a much to be said here, and this would stretch
this dictionary too much. I recommend reading [url=https://github.com/CyanogenMod/cm-kernel/blob/android-msm-2.6.37/Documentation/cpu-freq/governors.txt]THIS[/url], a very good explanation of
governors—from CyanogenMod. [/quote]
[B]OC (Overclock)[/B]
[quote]An overclock is usually one of the first things users
figure out after gaining root access on a new phone. If you
want to push your smartphone's CPU to run more clock cycles,
you have to know that extra power isn't coming from nowhere.
However, it is generally considered good practice, but it
depends on your handset. Some phones may be able to support
overclocking to 1.4 GHz, while others may never get past
1.2 GHz. Just proceed with caution. [/quote]
[B]Touch Wake[/B]
[quote]Yes, yes, Ezekeel again. This mod allows the user to
wake the device after a set amount of time, just by touching
the screen or the capacitive buttons. The time after which the
screen no longer responds to a touch is set with NStools. [/quote]
[B]UV (Undervolt)[/B]
[quote]This refers to lowering the voltage to conserve power while
still achieving the same performance, assuming your settings
remain stable. Both SetCPU and NStools allow the user to change
voltages. Like overclocking, this is also a trial and error process,
because each phone is different. The benefits are low energy
consumption and less thermal output. [/quote]
Tools & Mods​
So you have a rooted phone. Maybe even a custom Kernel or ROM, whatever works for you. But you still want to be a tad different from the other guys using the same configuration as yours. So here's a small selection of mods and apps developed by members of the community, enough to get you started. Feel free to experiment, and remember: read before flashing, search before asking and you should be alright!
Mods for AOSP+ Rom
[BOOTANIMATION] Plain, Simple & Colorful + color variants
Nova Launcher
Flavours for stock OTA ICS 4.0.3

NOTES:
I am hoping this little survival guide is useful FOR BEGINNERS in understanding the basic terminology used here in the Nexus S sections. As the title suggests, it was made with beginners in mind, so I don’t want posts of so called “experts” saying how they already knew this.
IMPORTANT: I do NOT guarantee the explanations written here are completely accurate or complete, FOR NOW. I will keep working on this, correcting mistakes as I continue to read.
If you find something that you think is not correct, or consider something must be added, please post here, together with a link to a credible source.
All of this came from sources off the internet, so please bear with me. Also, sorry for any typing mistakes. If you see any, please be sure to signal them
If I have helped you in any way, or if you appreciate the work invested in this (now and for the future), press the THANKS button.
Thank you! (Hoping to see this stick) And many thanks to all the great devs working on ROMs and Kernels for us. Keep up the great work!

nice thread! thanks
Hey great post, i still haven't rooted my nexus s but you just made me flash a kernal. I was tkinking about it but never too serious.
thanks!
Love it!!! Cleared so much up (you recieved my first Thanks button click!)
Just wanted to clarify something about the Kernel. My Rom is stock 2.3.6 that was received OTA when I unboxed the phone (Nexus S GSM i9020A, I'm in Canada). The bootloader is unlocked, phone rooted with CWM recovery via one click (QBKing's Video). Am I able to flash a custom Kernel to a stock Rom? Reading the above seems to lean towards the "yes", but wanted to make sure first.
Also, do not use the one click method on the Nexus S GSM if you want to easily return to stock. The one click stock only supports the 4G, which is extremely silly and inconvenient IMO. I'm currently still trying to figure out how to return to stock, incase something does happen and the phone needs warranty work. Let's just say, I'm not making much progress and this is extremely uncomfortable ATM..
Great thread and idea, all seems spot on. I vote for sticky.
Also, heX, you can flash a custom kernel on a stock rom as long as you have an unlocked bootloader and custom recovery. I'd recommend you backup all you need with TB or similar, then do unlock your bootloader if you havn't already (search around for how to do this, described in rooting guides). Just remember this will delete -ALL- user data, including sdcard. After this you can flash a su.zip to have proper root access, and you can easily install a stock image with a custom bootloader then lock the bootloader afterward for pure stocky goodness.
Thanks so much for taking the time to do this

TYVM Harbb!
Yes, currently the bootloader is unlocked, phone rooted and CWM installed. I did a TB backup prior so I could quickly restore my apps and settings. All is running well.
I tried to flash a full stock Rom back to the phone, but have run into an issue in doing so, posted here
I'm still awaiting some help with regards to that one, hopefully all will be well soon.
I'm not sure why I got spooked in doing this. I'd like to try the Matrix kernel and there are various Roms that definitely sound fantastic, but part of me just wants it back to stock so warranty and OTA are restored as the phone is only a few weeks old.
very useful for us newbie, thanks for sharing

Ok I see you have the att version, so i9020A. When android 4.0.3 came out, I wanted to go back to stock 2.3.6 so that I could update officially. Anyway, I downloaded a full stock ROM, flashable via recovery, from HERE and all went smooth for me. (the link is to the i9020A version, of course I used the i9023 version). Try the stock posted there, and see if you get any error. I think you should be ok now, if not, post back. Remember, this takes you fully back to stock, no cwm, no nothing custom.
I am glad to see that I helped somenone, I will make some modifications this afternoon, still 9am here (maybe add stuff to the dictionary and post it to google docs or something like that, just to make it easier to scroll through and more). Any suggestions or critics are welcome!
EDIT: Guide updated:
-better arrangement of the dictionary (will be adding new terms tomorrow, had to study for an exam today)
-added Tools & Mods section (will build on that later on)
-more to come...
great post OP
Nice thread! Great Work ,Thanks
Hey thanks! Happy to see good feedback on this.
Transmitted from somewhere in space... from my Nexus S... and Tapatalk.
Great beginners guide, and thanks for the link!
For kernel benchmarks and more, see here: http://goo.gl/mpeHI
Thanks very much! I will give it a try shortly, just to confirm if I recieve any issues. I've also installed the recommended CWM version for my model, not sure if it makes a difference, but I flashed 5.0.2.0 anyway as the version I was getting an error with had a higher build number.
Right now I'm enjoying AndroidME 1.2.3 with Speedy 6 kernel and have no complaints so far! (Kernel updated this morning from Speedy 5)
I will report back with any issues once I have some time to do a Nandroid backup and test the stock Rom.
Thanks for your help!
It's nice to know there's a way to revert back to stock, should anything need servicing! I've also started reading up on Odin

You're welcome! Looking forward to an update with your stock flashing situation. I also used ClockworkMod 5.0.2.0 a long time. I'm now on 5.0.2.3 only for the better menu layout.

just one question...
can i install more than one kernel at a time...
for eg.like one i installed for battery usage and othr for sound..
can i do tht

(Guide) (Beginners) You have rooted your phone, now what can you do

(Guide) (Beginners) You have rooted your phone, now what can you do​Note – I will keep updating this guide as much as I can
Note - Please ask as many questions as you need, there is no question to basic to ask, it would be better being asked here instead of starting a new thread.
Note – Please don’t swear in this thread fu**ing is still swearing, using this - ** - still means you are swearing. Also please don’t call anyone a Noob after all this is a guide for beginners.
Final note – Can all beginners please thank people if they give you an answer to your question.
So welcome to the world of being rooted, you now have a nice shiny new rooted Android phone, but what can you do now. Well I have decided to start this thread to tell you what you can now do. This guide is for beginners and should be treated as it is intended, keeping it simple and just going over the basics. This guide will be broken down into main sections –
Post 1
• Super User
• Clockwork Mod Recovery (CWM)
• Apps
• Roms
Post 2
Further reading, it’s time to get you geek on
Post 3
More usefull apps that you might like
Super User
When you have a rooted phone you will need this little app called super user that has a massive job. When you rooted your phone it will have more than likely come with this app, if not then you can download it here. The basic idea behind super user is to control the root access to you phone. Your phone must have this app before you continue with the rest of this guide. Using Super User is easy when you open an app that needs root access a prompt will come up asking if you want to allow this app super user access, giving you two options deny or allow.
Clockwork Mod Recovery (CWM)
Once you have rooted your phone one of first thing you need to do is make sure you have Clockwork Mod Recovery. All phones have a recovery mode that can be accessed when turning on your phone or some root access apps allow you to access recovery mode through them. What CWM recovery does is modifies this recovery mode to make it better, allowing you to flash nearly anything you want or need, such as roms, themes and kernels. Also through CWM Recovery you can create a nandroid backup, which is a backup of your whole current rom, you can also carry factory data wipes and more advance features.
So how do you get CWM, well the first thing to do is check, depending what root method you used you might have it all ready (power off your phone and then hold the power, home and volume up buttons together until you enter recovery mode). You will know if you have CWM Recovery by looking at the top of the screen is should say “Clockworkmod Recovery”; if it doesn’t then you need to get it. The easy way to get CWM is by downloading the app Rom Manager (talked about below), open Rom Manager and there is an option to flash Clockwork Mod recovery, select that select which phone you have and it will do the rest for you.
Controls for CWM Recovery – Then volume buttons allow you to move and the power button is used to select.
Apps
Right there are a number of apps that will take advantage of you root access, and I am going to cover what I believe are the basics.
Remember when using any app that uses the root access of your phone it can come with risks.
Rom Manager – So Rom Manager and CWM sort of go hand in hand, being that Rom Manager is the nice user friendly app, giving you control of CWM from your phone home screen. Just like in CWM you can backup and restore your rom, flash new roms, fix permitions and partition SD card. As said above you can use Rom manager to flash CWM for you straight from the app, you can download this app here.
BusyBox – Trting to keep this simple, when you have a rooted phone there are sets of commands that you do not have, installing BusyBox will give these. This is required to run some apps that require root access. I think that was simple enough, oh and before I forget you can get it here.
Titanium Backup Root – Titanium Backup is an enormously useful app. Not only can it backup apps, but it can backup apps and all their data, and it can delete apps—even system apps or bloatware (bloatware are apps that come with your phone that you normally can’t remove like Games hub), making regular backups of all your apps and their data. You can download Titanium Backup here, also if you would like to know more about how to backup and restore most things when changing roms (more about roms just below) you can use my other guide here.
These are the very basic apps that you will need to see you of into the future of a android custom android experience, I will include other cool apps that use root access in post 3.
Roms
So the best part about having a rooted phone well for me anyway is the massive list of roms out there. If you don’t know what a rom is then here we go. When you get your android phone and turn it on, you’re faced with this impressive software that allows you access to apps throught the market, make phone call, txt, maps, voice commands, email and the list is never ending. This is all done through the software known as the Rom, the rom you get when have your phone is known as a Stock Rom. Now it this stock rom that we can change to improve our Android mobile experience known as a Custom Rom, and there are lots of custom roms out there. Some are made to give you a better battery, better custimization, improved features, so to provide a vanilla experience and some try to make a balance of them all, but the main idea is to make android better. So roms are broken down into different categories, here is a breakdown of them for you.
Stock Rom – As talked about before stock roms are the software that comes with the phone, some people prefer the stock experience but I don’t. The main problem with stock roms is that manufactures will place an extra layer of software on top of the rom known as a user interface (UI), such as Samsung wither their touchwiz UI and HTC with HTC Sense UI. The problem I have with these UI are they are power hungry and well not to sound mean but touchwiz is not very well made.
AOSP – Android open Source Project is the android rom in its basic form, so it has no bloatware or power hungry UI’s. This is where you will get most of your custom roms from, there are devs within the android community most found right here on XDA, that will use AOSP and make their own custom roms with this adding to and improving it to make the best rom they can. Just as a note there is no best rom and you will never get an answer as to which is the best. Each rom is to their own and suit different people with different needs, but as a starter rom to get use to the idea of flashing roms and learning everything that is needed then I would recommend a Cyanogen Mod Rom, as this is the most popular and you will get the most advice from the community is it is the most used. You can find the Cyanogen Mod website here. The best way to find roms is to look through the forum and look in the Development and Original Development threads.
INDEX - Android Development [29 March] - Here is a Rom list from the Android Development Fourm, the list includes both ICS and GB roms, thanks to daniel_costa_rj
There is a lot more to roms that just this basic overview and I will be adding more in the future as this will take just as long as writing this whole thread, so keep an eyeout for more updates, including AOKP.
EFS Folder (Important)
Ok this is more of a you must do and not a what you can now do. So the efs folder is a very important folder within your android system that contains infomation like your IMEI number, and just well important infomation trust me it's important. When people start to mod their phone such as flashing roms, kernels e.t.c, this folder can become corrupt, making you phone usless. So backing up this folder is important and their is an easy way in which you can do this, a more user friendly way using a great app by hellcatdroid. You can get this app from google play here, and it will give you all the tools to back up the folder. I will also include a guide on further reading for you to have a look over, so please backup your efs folder.
Well that’s it for now, this is my first draft and I will be making a lot on adding and changing over the next week.
Thanks for reading and I hope this guide helps even a handful of people.

Introduction to Kernels
What is a kernel
So to keep this simple their 3 parts of your device the hardware, Software (rom) and your kernel. The kernel is the communication link between hardware and Software, although some of the seen as more important things are battery life, touch, wifi and more. You can also use a kernel to give you greater controll of your phone with such things (each kernel has its own conrtoll features).
You can swap your kernel just like you can swap your rom, although you need to check that the kernel you are going to flash with work with the rom you are using. some kernels will work woth all rom types such as SiyahKernel, others are made to be used on certain roms only such as Stock Roms, AOSP roms, AOKP Roms, and some even more specific such as CM9, MIUI and diffrent versions such as GB and ICS. So you will need to check the thread for that kernel and see what the features are and what Roms it will work on.
Their are many kernels on XDA Develpoers and the idea is for you to try a few out and see which suits your needs best, as their is no best kernel, the same as their is no best rom. So here is a list of a few kernels to get you started, and remember to check that the kernel you are about to flash will work on your device.
[KERNEL][ICS][ExTweaks][All-in-1kernel][DualBoot] SiyahKernel v3.2b6
[KERNEL][05.05][APP/PRO/OTA][AOSP&SAMMY] N.E.A.K. ICS - Designed by Nature (v2.0.4x)

Great guide
u said that u can flash new roms now that your phone is rooted but my question is dont you have to unlock bootloader to do that
i'm still new so i'll ask alot of questions
If you install ClockworkMod Recovery, it will allow you to flash roms as it will unlock bootloader for you

ok then nevr heard of that but i'm still new to everything
would clockwork mod unlock the bootloader of xperia play r800i i recently rooted it(last night to be exact)
i know this may not be the xperia play section but i was searching and stumbled upon this thread

Update to thread
I have updated the thread a little with more guides for you to geek up on, and i have added a link to a rom list................ Enjoy
Just a thought mate, how about linking up a thread on how to back up your efs folder after root, last few months been lots of threads about efs being messed up, there is also a guide to re-storing ya efs if ya screw it up. Nice thread btw

This is very helpful indeed.

[Q] Nexus 7: A Beginners Quest!

Hi guys!
I bought a Nexus 7 a few days ago, This is my first Android device, my first tablet and my first attempt at rooting anything. so I was hoping for some help from the experienced folks because frankly i don't know what I'm doing I was hoping you could help me with a sort of beginners guide for rooting, like what i should look out for, whats the safest and easiest toolkit, rom, kernel to use. I know i have so much to learn from you guys and I've been reading some of the threads and im starting to get a bit of it already just asking for a step by step of what i should do im mainly going to use my tablet for torrents, games, and some light photo editing and lots of comics! so how do i start? hope to hear from you guys soon THANKS IN ADVANCE!
For rooting the tablet ..its safe ,the important thing is to follow the instructions .so to root it you can use one of the toolkits in the development section,I preferred wugfresh toolkit more ..but its up to you the other one is also good ... Here's a video which explains the root procedure
https://www.youtube.com/watch?v=wI0_ylxyrWA&feature=youtube_gdata_player
btw update your phone before rooting it
And for flashing Roms there are a lots of guides on how to do it..just use Google
If you got stuck in any boot loops just use the toolkit you first used, to restore to stock or restore with a nandroid backup
Most important thing when you root. before touching a file ..do a nandroid backup in recovery to always stay safe ..
That's it enjoy the forums

well said, but here are some more tips: DO NOT PANIC!! when something goes wrong, which is likely, as you are a newbie to rooting, one thing you must not do is panic. calm down and troubleshoot, what did i do wrong? how do i fix it? and according to my experience, whenever a door slams shut behind you, a new window opens. if one method doesn't work, try another method.
also, read through the entire procedure list before start doing the steps. make sure you understand what is required and how to do it before accidentally doing something stupid. believe me, its happened to me b4, not a pleasant experience when you realise you dont actually meet the criteria to install something. btw, here is a list of common names given to the nexus 7: Nexus 7 (duh!), N7, grouper (wifi only) Tilapia (wifi+3g)
good luck rooting!
Read through the stickied threads and try to understand them. It won't happen right away though; your head will probably spin the first couple of times through.
There is really no "overnight" learning curve to this stuff - even if you are an old hand with Linux/Unix.
BTW, it is important to point something out: There should be no reason for you to feel like you should be in a hurry to root. The N7 is a fantastic device, even when used in a pure stock experience.. You are not going to be missing out by not rooting immediately. Spend some time with your device getting used to the Android way of doing things, and start reading XDA with a relaxed frame of mind. There is plenty of time. It would be different if you have lots of prior Android experience - but you said it - this is your first Android device.
OK, rooting. To try and keep you safe while you are a noob, I'll give this recommendation:
If you see the word "flash" (verb) near the word "bootloader", RUN AWAY!.
The most dangerous thing you can do to an N7 is mess around with the bootloader. You can turn your device into a useless object by getting things wrong, and it is a little bit rare that you need to flash a bootloader anyway. You have been warned.
So, make sure you know the difference between bootloader and "boot partition".
Most Android devices have a single flash memory chip in them which is divided up into a number of partitions. There are 5 principal partitions and about the same number of less frequently used partitions:
THE 5 PRINCIPAL ANDROID PARTITIONS:
(B) boot - a raw blob of binary data containing a "kernel" and a "ramdisk"
(B) recovery - another raw blob of binary data containing a "kernel" and a "ramdisk"
(F) system - The "ROM" part of Android - all the factory (or customized) software, used read-only
(F) data - User data and customizations. A "factory reset" simply erases all the files here
(F) cache - a scratch area used for downloading files and other maintenance operations
B = binary, bootable
F = Filesystem
Now, the two bootable partitions - boot and recovery - are very similar in structure, but extremely different in purpose. (In fact, in stock devices, they both use a private copy of the same kernel) The "boot" partition can produce a UI (User Interface) after it starts up only in conjunction with healthy /system and /data filesystems containing the Android software. But the "recovery" partition can produce a minimal UI even if the /data and /system filesystems are completely empty of files; so it (the recovery boot) is used to do all maintenance operations - including things like installing new /system software or erasing all user data.
So, and Android "rooter" will usually replace the very minimal (and locked-down-security) stock recovery partition with a "custom recovery" that is more friendly, and the vast amount of the "flashing" operations will take place using this custom recovery.
When people talk about "ROMs", they generally mean only TWO of those five partitions mentioned above: the "boot" partition and the "system" partition. When a "ROM" is flashed using the system partition, the usual procedure is:
- The rooter makes a full Nandroid backup.
- The rooter performs a "factory reset" procedure which erases the /data*** and /cache filesystems
- The rooter then "flashes a ROM", which puts in place a new boot partition, erases the /system partition, and then re-populates the /system partition with changed Android system software.
Upon booting an Android phone/tablet after this procedure, the device will behave as if it just came from the factory - but now with a different custom version of Android software. Note that this means that all the things you customized in the previous ROM - wallpapers, settings, home screen app icons, widgets, market apps downloaded, etc - will all be gone. So, folks that make a habit of hopping from ROM to ROM generally have some tricks up their sleeves for making the re-customization of a freshly-installed ROM a little less tedious. (Things like using custom launchers that allow you to save homescreen customizations, apps to restore previously-used market apps & their data, etc, etc, etc)
*** there is some funny business with Android devices that have no removable SDcard storage devices such as the Nexus 7 - the user's "SD card" is emulated, and the files that are stored there are actually stored in the /data filesystem. So, custom recoveries usually have a "factory reset" procedure which deletes all files in /data while scrupulously avoiding erasing things in this /sdcard area ( == /data/media ). This allows you to keep things safe from wiping (pictures, music, ROM files, backups) while still installing a fresh and un-initialized ROM. Note that the stock recovery in the N7 does not do this - when you use the "factory reset" of the stock recovery, EVERYTHING in /data gets erased - everything!
While you are reading about Android, here are some questions/searches to look up that concern rooting activities... have fun!
- What is the difference between grouper/tilapia (or nakasi/nakasig )?
- What does it mean to "install a new launcher" or "install a new home app"?
- What is Android fastboot used for?
- What is the Android ADB (Android Device Bridge) program used for?
- What is the difference between a boot image and a bootloader?
- How do I go about making a Nandroid Backup?
- What are the Carbon and Titanium Backup apps for? What can they do?
- What file browsers on the market are "root aware"?
- What Android settings can be saved by the Google Play Store, and automatically restored into a new ROM?
- Is there a difference between the "Superuser" and "SuperSU" root kits?
- What are the special Hardware Button Combinations used by the Nexus 7?
- What is the Google Android SDK?
- What custom recoveries are available for the Nexus 7?
- How many unique operating modes does the Nexus 7 bootloader display? What are they called?
- What is a MD5 signature? How can it help me stay out of trouble?
- What does soft-booting a bootable image with fastboot do?
- How many (Windows PC) drivers are needed to use ADB (with both the custom recovery and also the regular OS) and fastboot (with the bootloader), 2 or 3?
- Suppose I soft-brick my N7 - how will I transfer files to and from the N7 in this situation?
- What is the difference between adb push/pull and adb sideload?
- What does "sideloading an app" mean?
- Is an Android ".apk" file the same thing as a .zip file, or different?
- In what folder in /data are market apps (.apk files) found? Same question for /system and system apps (.apk files)?
- How do I enable the developer options on my N7 tablet?
- What are the limitations of MTP or PTP file transfer modes?
- Where does the custom recovery tool store backups?
- Are the Android tools "adb" and "fastboot" available for Mac or Linux?
- What are the limitations of the Google Factory Images for the Nexus 7? How are they installed?
- I have a problem using the recovery. Where is the log file stored?
- What is the big stumbling block involved in unlocking the N7 bootloader?
- What operations can you perform using fastboot and the bootloader which you can not do any other way?
OK, that's enough for now.
Thanks Everyone!

I do appreciate everyones input! yeah i think ill make do with the stock for a couple weeks while i study up on rooting and firmwares. well the main reason i wanted to root was for the games, as much as i want to buy the games i like, i dont have the means to
This is great. Wish I had been fortunate enough to have such great help when I first started.
And the most important rule is the one about reading before you root or flash. This will save you some heartache down the road.

All the help you were given....then you bring this up.
I doubt further help will come your way as pirating software is very much frowned upon at xda.

a good way to get started is to get yourself a prepaid credit card from 7eleven and use that for purchases from the play store.

Hey guys, what do you think are the most basic and necessary apps that i should get ? running on stock
, ive checked some and go a file manager
If you think you are going to root down the road...
If you think there is a good chance that you are going to root down the road, I would suggest unlocking the bootloader in the near future. You'll need to do this and it wipes everything on the tablet. Even if you don't root, there's isn't any major downside to having the bootloader unlocked and you can always relock it later.
It's better to do that before you've put a lot of time into customizing your tablet to perfection and then have to redo it all.

New phone, new brand, new questions!! (KIND OF URGENT)

Hello everyone, Ive been lurking around your little forum here for the sake of customizing/upgrading/etc my new e612g.
First of all, I may say that I am semi-well-versed on android stuff, but this being a whole new brand Im dealing with I am CONFUSED!:silly:
Ok so onto the questions:
First of all and my main regard here: The system partition is freaking full, only 4 mb left. Ive deleted most bloatware and moved some apps to sd, changed system to user apps someones, and all of the "usual" tweaking.
I am currently on stock 4.1.2 (20d-rooted-unlocked-cwm KDZ that is found here)
Next question: I have a big misunderstanding on KDZ files, can they be modded, if so how???, I mean can I use the kitchen to build/mod a say stock rom and somehow convert it to a flashable KDZ? (I really like the flashing software, much more informative and fool-proof than RSDlite)
speakin´ about flashin´... Is there any way I can flash a KDZ, and keep my apps and data? I I remember flashing CM updates on my moto devices w/o wiping and stuff...
Next question: from what I´ve heard, there is a kernel developed by chachasomeone (big thanks dude!) which I use, which is able to recognize and manage a swap file... Ive hear just using rAM expander something app you can create and autoload the script for loading the swap file at startup, but again Ive read a lot this two past days, and somewhere here on XDA a user of the e612 damaged his phone by using a swapfile, and another "lost" (if you can really think something as inexpensive as a microSD is lost!!!) his SD card by means of bad swapfile implementation...
any advice on this?
And finally, this is more a recommendation than a question, Ive observed that the information here is really, really, REALLY sprayed around forums and themes, no centralization like with other devices. To an unexperienced user, this will be hell. Heck even I was really confused on where to look for roms, answers, etc.
Anyway you guys could separate themes, maybe merge some threads and overall, on top of that "new" thread just for god's sake tell everyone that e610,e612 and all the alphabet after them are really the same phone!!!! Dude I freaked out last night when I was flashing that KDZ I have right now, and looked into my phone´s box and it said E612g, but the update said it was ONLY for e610...=
Obviously it worked just fine, buuut someone unexperienced will, and will always flood the forums with questions (the I cant find the search button syndrome)
Thanx for your attention, donlloreda out.
BTW I´m really satisfied so far with this phone, Snappy, fast, plenty of internal storage (though it´s crippled) the creen sucks but just go ahead, set the lcd density to 144, install a nice, clean font (like segoe UI, or Segoe WP, or Helvetica, or some Adobe font, and you´ll se the eye strain go down..)
BTW, just dont download any font, go to your build.prop and search at the bottom for a line saying something like lge.fonts=true, change it to false and voila, you now may choose from all the availible fonts installed. that line limits you to roboto and lg something.
Build.prop tweaks for this phone anyone willing to share and/or test????
Goodnite!
