Backup existing Kernel - Adb or Zip file mothod - Nexus 4 Q&A, Help & Troubleshooting

Hi, I'm trying various kernels on my rom.
Therefore I'd like to backup my existing kernel.
I know TWRP can easily do this.
However for information I'd like to know manual adb method, or terminal commands.
Or is there a Zip file which I can run to automate the process

why not just keep the kernel zip file in your storage?
as a hobby, i test kernels, trinity kernel to be exact. i probably have 20-30 kernels in my storage at all times. when im want to run my favorite again, i just reflash it. i cant imagine why id want to back up a kernel.

[Q] Custom ROM developing

Hi just asking if anyone knows any links or archives or anything i can read through, im looking to build my own ROM. any help would be much appreciated and dont mind donating to someone that can help me start to learn.
Thanks
Well, first of all you need to be able to compile Android. This is pretty easy and it's explained directly in the developers google website. If you're not running a Nexus One or a Nexus S, you can't actually compile a working android copy for your own phone "as is" from AOSP. Because of this, you firstly need to change / create some dirs and files in order to add the support for your particular device. I'd start searching on CM repositories for this (I've got the Nexus One and thus I don't have such problems).
After you've compiled Android for your device and your changes (for example root), you'll have some disk images (you can find them all under out/target/product/PHONE_MODEL/, they are the .img files). You can directly flash them via fastboot ("fastboot flash boot boot.img" etc.). You can though create an update.zip file, and this can be made extracting the system.img file in a folder. Remember that you'll have to recreate the symlinks (to toolbox and/or busybox if you want to include it in your build) and set permissions, as zip doesn't save the permissions of the files once compressed.
Thus so far, if you succeed making every single step you should have your ROM on your phone

[REQ] Kernel that supports Overclocking

I have been a fan of DJ Steve's ROMs and his dev skills. But right now I am running a deodexed 351 that is otherwise stock, in portrait mode. haha
I love his ability to compile ROMs and Kernels and such, but I really want just the kernel that supports overclocking.
I can get any of the kernels to work from 1.91
no vol, no ppt
no vol, ppt
vol and ppt
vol and no ppt
I even add the proper dhd.ko file for the modules folder and correct the permissions and even the reset.ko file too.
But no matter what I do, I can't get the kernel to work AND wifi to work. It seems like either or for a stock rom. Either you have a plain kernel with no overclocking, or you can use the kernel with no wifi working.
Does anyone know of:
1: If there are other files I should be bringing over from the rom to make the kernel and wifi work together
or
2: What specifically I can edit to allow the stock kernel to allow overclocking?
Sorry for the long post.
Thanks for the help in advance.
OK. I guess no one out there knows either.
What I have been doing so far to achieve overclocking is create a .txt file (according to the instructions on setcpu.com) and put that at the root of my sdcard and have setcpu do the rest.
I would prefer to use the kernel method so I can add the volboost and/or ppt tweaks in 1.91.
I will wait patiently for your guidence.
Maybe try this

Ok I figured out which one will work.
http://forum.xda-developers.com/showthread.php?t=1113256
Ok go to Simple Streak's thread.
1. Download the .zip for version 1.2
2. copy the files in /system/lib/modules to your /system/lib/modules
3. fix permissions, they should be 644, which are rw-r--r--
4. boot into fastboot, and flash his boot.img
Thank you Spidla for a kernel I can use that supports overclocking, that I dont have to use the entire ROM and most importantly, my wifi works.

Can't write on internal SD card after root

After having rooted (with nexus 10 toolkit v1.3.0) my nexus 10 and flashed AOPK Nexus 10 (WIP) Task650 & Ktoonsez (1-4) rom, I'm unable to upload to, change or move any files or folders on my internal SD card. I installed Root Explorer and changed from Mount R/O to Mounted as r/w. Access is granted by Super SU. I also tried to change permission settings, unfortunatedly without any success. There appeared the following message:
"Warning
Permissions change was not successful. Please note that some file systems (e.g. SD card) do not allow permission changes."
Is there a possibility to change these permissions in order to be able to create and move files and folders on my SD card?
Thanks for taking your time to help me with my issue!
Anzirothu
1. Clear cache
2. Clear dalvik
3. Fix Permissions
forgot something ?
Thank you for your reply, Patrik!
1. done.
2. done.
3. Fix Permissions - How? With cwm? I did fix permissions with cwm recovery, but the problem persists...
Just so we are clear, when you say "upload to, change, or move" are you meaning you cannot copy a file from your computer to your Nexus 10? Or just that you cant arrange stuff through root explorer from within the tablet itself?
Neither copying from PC to Nexus nor arranging stuff through root exlorer from within the tablet itself. I can't even download an email attachment and put it to the SD card. The card seems to be locked.
I had that problem once but I dont remember what caused it or what exactly I did to fix. I think I just did a complete wipe by locking and unlocking the bootloader and then installing a new ROM again.
I think I did this too (unroot, lock bootloader, then root and unlock bootloader) and then installed the same rom again. I will try it this time with another rom.
Isn't there really no other solution to get access to my SD card again??
Thx for your help!
Are you using a toolkit to unlock and root? If so them maybe it is not doing something right and it messing up a permissions somewhere. It could also be a driver problem on your PC with being unable to copy a file to the tablet.
Thank you for your help!
I am using the nexus 10 toolkit V1.3.0. Right now I'm trying to intall twrp recovery with a fully wiped sd card. No easy task fot me being a noob...
In ClockWorkMod, make sure that /data is mounted
Then download the Android SDK: http://developer.android.com/sdk/index.html
I usually put all the files just in C:/android-sdk-windows
Once you have it all there open up the SDK Manager and download all the additional files needed. You probably only need to download "Android SDK Tools" and "Android SDK Platform-tools", but I always download the other files for whatever version of Android I am running, in our case Android 4.2. That way I have them if I need to do something else.
Once downloaded, open the Android-sdk-windows/platform-tools directory. copy:
adb.exe
adbWinApi.dll
adbWinUsbApi.dll
fastboot.exe
to your base C:/Android-SDK-Windows directory.
Now open command prompt from Start -> run
type: cd C:/Android-SDK-Windows
type: "adb devices" and it should list your tablet. It will actually say something with your devices serial number and then "Recovery" after it, showing your tablet is in recovery. If you dont see this then you either dont have your tablet mounted right from in the Recovery, ClockWorkMod is stupid, or you dont have working adb drivers.
Now copy the ROM you want to flash to C:/Android-SDK-Windows
Then type: "adb push blahblahblah.zip /data/media/0"
That should push the ROM to the root of your SD card. Give it time, it takes a while to push a ROM file. Once it is done, flash the ROM.
That *should* put it in the right spot where it looks like it is on your "internal storage" (what you see when navigating files within the ROM). If you dont see the ROM in clockworkMod then keep navigating back to the root of your internal storage and then open up "data", then "media", then "0" and you should see it. If you still cant find the ROM, push it again but just use "/data/media" as the location.
I just did all these steps myself to verify I remembered it all correct and I was able to successfully copy a ROM and find it on my tablet to flash by doing everything I just listed above. SO you should be good to go if you follow all those steps properly. I know it looks like a lot of work, but it really isnt and will go quite fast. Most of it is just the setup for getting ADB and Fastboot ready to use.
For a ROM to install, I would recommend to someone new like you either of these:
http://forum.xda-developers.com/showthread.php?t=2071082
^^^^^ That one is pretty close to the stock ROM with a few fixes and a couple extra features
or: http://forum.xda-developers.com/showthread.php?t=2071082
^^^^^ This one is pretty much CyanogenMod 10.1, but built by a different guy and not pulling every new thing from CM, just the "cherry picks" of features. It tends to be a bit more stable and less buggy than the real CM10.1 nightly's
And for a kernel you can flash and forget you will want to try this one:
http://forum.xda-developers.com/showthread.php?t=2098157
^^^^^ To flash that you will want to do a similar thing as how you pushed the ROM to your device. Only this time you will copy the kernels' "boot-r4.img" file into your android-adk-windows directory and use the command: "fastboot flash boot boot-r4.img"
While I enjoy the KTManta kernel more, it does require a bit of tweaking to get running perfect. Which is one of the things I like about it because of all the options to tweak. But for someone just learning this stuff that would be a bad thing, so Franco's kernel is much better than stock and doesnt require you to adjust anything once it is flashed to your tablet.

[GUIDE] Get Xposed working on your deodexed TouchWiz based Lollipop ROM! 2015/08/17

DISCLAIMER
The process of flashing a custom recovery/kernel/firmware may and will trigger your device's Knox Counter. Neither XDA nor I can be held responsible for your actions. Proceed with caution. During this process you will lose all your settings and apps. As long as you follow the instructions, your device's storage, internal and external, won't be touched​
Still not compatible with x64 systems! Not compatible with Samsung 5.1.x (sdk22) ROMs!
Hello, Ladies and Gentleman
Many people seem to have a hard time to understand how all of this here on XDA works. I constantly get PM's from users, asking how to do the most basic stuff like flashing a .zip or stock firmware via Odin. Usually, I don't even read them and just hit delete. I know it's not ok to deny people help, so I decided to show you how you can get Xposed working on your TW based stock or custom ROM since it's the most frequently asked question I get.
It's nothing you couldn't do if you'd just....
We're going to use @arter97's customized Xposed Framework as the one made by @darkera13 needs the user to manually modify and replace files which may be too complicated for some.
Preparation
-READ EVERYTHING OVER AND OVER AGAIN.
-A custom recovery System like TWRP or CWM (PhilZ or Stock)
-A deodexed ROM. It's the only way to go. YOU NEED A DEODEXED ROM. If your ROM is not deodexed and you flash the framework, you'll end up in a bootloop. To deodex your existing ROM carefully follow Post #2
Here are a few made by XDA Senior Member @_alexndr
Stock deodexed for SM-N9005 Galaxy Note 3 International Qualcomm.
Stock deodexed for SM-G900F Galaxy S5 International Qualcomm
-And the framework itself from here
[UNOFFICIAL] Xposed for Samsung Lollipop by arter97
-Flash a custom recovery system of your choice. This is listed under preperation on purpose since this guide is about getting Xposed on your TW Lollipop device. A guide on how to get a custom recovery system is most certainly available in your device's forum.
-Store the ROM and the Framework in an easy to find folder, which we're gonna call "folder x". It doesn't matter where you store it (ext. SD or int. SD)
The Fun Part
-Boot into your custom recovery and make a full wipe:
TWRP users: "Wipe>Advanced Wipe> Tick System, Data, Cache, Dalvik Cache> Slide to format.​CWM users: "Mounts and Storage> hit Format /System; hit Format /Data; hit Format /Cache.​
-Still in recovery system, install, or flash the files we put in folder x;
TWRP users: "Install> Navigate to folder x and choose the ROM file first> Add Zip> now choose the Xposed Framework from folder x> Slide to flash.​CWM users: "Install Zip> Choose zip from /sdcard if folder x is on internalt storage or /storage/sdcard1 if folder x is on ext. storage (SD-Card)>​choose the ROM file first> -Yes - install ROMXY.zip.​Do the same with the Xposed Framework zip file.​
-Still in recovery system, reboot device and wait for it to boot. It can take up to 20 minutes. Enjoy Xposed on your Samsung TouchWiz Lollipop ROM.
-Stuck in a bootloop? Try this and repeat the process.
XDA Senior Member @Honzze kindly pointed out to keep following in mind; You have to start JoelDroid Lollipop Batch Deodexer with Admin permissions. Otherwise this error might return "path variable" of Java "is not set".
Deodexing your existing ROM without having to flash an entire ROM
As the title says, with this awesome guide by XDA Senior Member @townsenk you don't have to reflash an entire new ROM to your device. Instead, youll just deodex those parts of your System which need to be modified in order to get Xposed working. You don't necessarily have to perform a full wipe if you do it this way. But if you encounter fc's or end up in a bootloop, you know what to do
Guide for this guide:
Regarding point 1: "...launch a DOS shell..." just means, you need to open the so called "CMD" programm in Windows. To "launch a DOS shell" or CMD from within a folder, you simply have to hold down the shift key and right click in that folder. The context menu will show an entry "open command window here". And that's it! (Windows XP users may have to search the internet for another solution)
For Galaxy S5 and Note 3 users: If ADB returns "device offline" or an empty line after "List of devices attached" make sure your using a USB 2.0 data cable on a USB 2.0 port

How to DeOdex YOUR (...) Rom.
I would like to note that I appreciate all the work that developers have put forth in creating and maintaining modified Roms. there are some awesome feature rich implementations available. My intentions are not to be critical of any specific Rom or mod. Without the developers we would have nothing.
(...)
This method is very common knowledge I thought I'd just explain it in an easy to understand way.
Here is what you need.
A stock (...) ROOTED configurated phone. Debloat as needed. Set the phone up exactly how you like it with apps and such.
Make sure it's stable. (If you have issues before DeOdexing they will be there afterward!)
Here's the files you may need to make this happen
LBD2.4.zip
7-Zip
Installer template (at end of post)
1> Make sure ADB is working on your computer. USB debugging turned on. Create a folder to store your soon to be download system files and launch a DOS shell from that working folder. Working folder name should NOT contain spaces. With the phone hooked up you should be able to type adb shell and get a prompt.
2> Type these commands
adb pull /system/app app/
adb pull /system/priv-app/ priv-app/
adb pull /system/framework framework/
This will take awhile and you will be left with three folders
Create a new folder named "system" and place these three folders inside.
3> Extract and launch LBD2.4 (This is the DeOdexer and is AWESOME). Point it at your recently created "system" folder and let it do it's thing.
I'll assume this will occur without errors as I have never had any.
4> At this point you can manually apply modded apk's to the system folder but I don't really recommend it. They can be applied afterward using the seperate installer zips.
5> with 7-Zip installed open the provided Installer template. Do not Extract it. Just open it in the 7-Zip file browser using the right click context menu in windows.
Drag-Drop the contents of your system folder into the empty system folder in the 7-Zip browser It should be the three folders previously created but now they are Deodexed. Close the 7-zip file manager and select Yes if it asks you to save.
Note: The provided installer template has been modified to only wipe and replace the three system directories.
6. Copy the created installer to your sdcard and install with recovery. Wipe cache and Dalvik before rebooting.
Go have lunch. You will sit at a boot screen for about 10 minutes. Then another 20 to rebuild caches. Time varies.
7. Your system will now be Deodexed! At this point you can install your mods one at a time, I recommend this so you can test your system between installs to determine if a specific mod is creating problems.
This method has so far removed ALL of my stability issues.

Since I no longer own this device, I'm retiring from this thread as of now. Hope I could help you.
Don't know if someone can help me as you stated that you're retired from this thread.
I did every step you do mentioned here (for self deodexing existing rom)
I did everything successfully and deodexed my files with 2.5 deodexer, putted files in the system folder to the 7zip folder and sent to my device and flashed zip, cleaned cache and dalvik and it stuck on booting for about 15 minutes. I know, it takes alot time during rebuildup of cache, but guys, it's 15 minutes! for me, if i cleanup cache and the dalvik/art cache, it just takes 1minute on boot screen to show up the image of each apps cache, but i just sat there with lots of patient for 15 minutes or a bit more and still same, stuck in same crappy booting logo.
I did restore my system files, now i'll try to retry it and send it again. Im suspicious of the zip file being corrupted during trasmitting to Device, however install was a big success so im very sure it wasnt corrupted. I'll do 2nd test and see it again if it's happening again.
If it does, i'll most likely try to figure out other ways to deodex as there is already deodexed roms out there, so they must have done is somehow.
Thanks, hope someone can help me out with this.
P.S: My adb works fine, i got usb drivers for my device, i got usb debug on, i got lots of space on phone, i got TWRP recovery which got very high compatibility when it comes to install anything from zip via recovery where almost all roms do work stable with TWRP.
omg brilliant @nitrous² ! thanks so much! its been days i keep trying to deodex with others tool...

Nope, i ended up using CM12 (at that time, right now i got cm13 update).
Well i had to deodex apps to get xposed on TouchWiz, but i failed and didn't get headache because of the Xposed modules being not really well compatible on TouchWiz, so i jumped to CM, i find it more stable, and the CM13 is insane because it saves so much battery at stand by, compared to lollipop, the Android 6.0.1 Marshmallow is the biggest update in android history, that saves hell lot of battery (it can be also maybe because i don't have Xposed Framework in recent rom).
Anyway, im tired of it, and i don't need to hassle with Link2Sd because of Android Marshmallow offering to mount the SD Card, in the end, all my needs are being offered in this (for me) huge, best android update, being Marshmallow.
Try it i would say, so amazing.
Ok i would like to go to cm13 as you but i stil need the support to the gear s smartwatch so i decided to stay with touchwiz without xposed.

how to build a flashable deployment file

HI,
I have looked at various tutorials and can't seem to find one specific to what i am looking for. Apologies if it's out there and i just haven't found it.
I have a bunch (like 250) of brand new Samsung Note 3's (Canadian N900W8 build) that have stock 4.4.2. I am required to get them all configured with a specific set of apps installed and various shortcuts on the home screen along with some custom settings (APN, data limits etc). so far i have been doing this manually and it is very time consuming and tedious. If there a way to take a phone i have already configured and make a file that i can flash in odin to each of the new phones that will mirror all of the changes i need to the new phones? Or some other tool to automate the process of deploying that many devices. If anyone can point me to a tool or tutorial i would be eternally grateful and may manage to retain my sanity.
I haven't seen anything like this yet in my browsing, most of the tutorials i have seen are for compiling/building a full rom.
Thanks

This might not work for reasons I don't know about, but why not make a nandroid backup of the completed ROM and Apps etc, and copy it to multiple extSDCards then run a Restore on each phone? Although I guess you'd need to flash a custom recovery first... hm...
Maybe someone who knows ADB ins and outs could suggest something - connect phone, push SW out etc.
So i found a tutorial that described how to dump an img file for various partitions using ADB commands. I used the following to dump the system partition
Code:
dd if=/dev/block/mmcblk0p23 of=/mnt/extSdCard/backup/system.img bs=4096
I then coppied the system.img to computer and used a tool i found on here to convert it to system.tar.md5. I put a new phone into download mode and open odin load the system.tar.md5 into the PDA section it verifies the file ok, but when i try to flash it it fails instantly and a message appears on the phone saying "Unsupport dev_type"
I have seen a couple different versions of this tutorial out there, and i even tried booting to a ubuntu live CD to try to use the linux commands i saw on a different tutorial to convert the .img to a .tar.md5 but the result is the same.
Does anyone have any experience getting this method to work? any suggestions?
Thanks

Maybe check adb setting in Developer menu? There's an ADB over network setting in there. Not sure if it will help, after looking at it it says it is reset on boot...
I ended up using a nandroid backup as suggested earlier. However i initially had issues doing that i think because i was using TWRP recovery and it requires the backups to be in a folder named uniquely per device id or something which requires you to make a backup on that device before you can copy the backup files . TWRP also write protected the backup folders requiring root to be able to copy a backup onto it.
I changed to CWM and it works much better, all i have to do is flash CWM recovery to a new device and then boot it to copy the backup files and then reboot to recovery and restore the backup.

Make sure all the devices have the same bootloader and modem. What Firmware version are you using as a base?

They're all using the same 4.4.2 base image, the only change i made was flashing a custom recovery to be able to create the initial backup of the configured phone and to restore the backup to the stock phones saving me having to maunally configure each device.
