CM7 vs CM9 kernel

Hello,
I have old Defy with Bayer module. Which software is better for me? I heard that GB kernel has a bug - full CPU thortle. But when it happens ? Does CM9 have any other bugs ? And is it possible to record videos on this?
Thank you for answers !

Hi,
which Kernel is better is related to the software you are using. But you can't be wrong to use the CM7 Kerner with Quarx newest builds. If you want to use Cyanogenmod 9 I would also recommend you to stay on Froyo-Builds, it causes less problems with the camera.

Im of course considering proper kernel for proper CM7 version.

If you use CM7, I see no reason to change to a GB-Kernel-Version, cause it makes nothing better. In additional the newest nighties are made by Quarx for the Froyo-Kernel. See on ge. tt/8rDd1nC
Edit: No space between the dot and the t

But I've heard that GB kernel is much faster... This problem with max CPU use is problem of soft and will be never fixed on this kernel ?

kernel doubt
hi sorry to bother you
i flashed cm7.1.0-rc1.5-jordan-signed.zip a couple months ago, working fine.
i've been wanting to try out the new cm9 builds.
mi kernel version is [email protected]# 1 i dont know if this "froyo kernel" o "gingerbread kernel"
1_which rom sould i flash... quarx (29 jan) or epsylon3 ( 31 jan)?
2_do i need to flash another kernel previously?
3_what steps do i need to take to flash it?
4_will i be able to downgrade back to froyo 2.2.1 or at least my current cm7 ?
thanks a million

1) both roms use froyo kernel, so you can try anyone.
2) you don't have to flash any kernel, cm7 uses froyo kernel aswell
3) I've just flashed 31Jan, I was using cm7 previously. What i did:
-reboot, when the motorolla logo displays, wait for the blue led to show and then press volume down.
-then you go to recovery, latest recovery. (I highly recomend to do a backup (nandroid) before wiping data)
-wipe data/factory reset, wipe cache.
-install from zip file, and choose either 29jan or 31jan zipfile. (remeber 31jan has gapps included, if you go for 29jan you should install gapps too)
-wipe cache.
-go to advanced, wipe dalvik cache.
-reboot!
First time to boot will take some minutes.
4) If you want to get back to cm7, just recover your backup (nandroid) or follow the same steps in 3) but installing cm7 zipfile.
Hope it helps you, if any more experienced user finds an error in what i've said, please correct me.

Thanks for the correction, but I've just came back to CM7 by restoring my old nandroid, without wipe and worked well.

camera doesn't work.and some small bugs

Going from Apex to CM7

So I have a Droid 2 which I rooted and have run Apex RC3 on since last fall. It recently has slowed down a bit and I have wanted to try switching to CyanogenMod7, but the whole concept of downgrading and then rerooting and then finally flashing the ROM seemed quite complicated.
Is that in fact what I have to do? I'm on 2.3.3, not 2.3.4 (I know there's a problem with downgrading from that), but is it not possible to simply flash CM7 from my current situation? It seems kind of redundant to unroot my phone just to reroot it again.
Finally, I am using Titanium Backup to store some data and I have a few questions. First of all, which one of the many contacts options is the one that actually stores my contact data? I would prefer not to backup and then restore all five or six of them. In addition, if I am forced to flash back to stock and unroot, will anything happen to my backups (obviously I can't use Titanium Backup while unrooted, I mean once I finally reroot and get CM7).
Thanks in advance for any help!

Find the version of CM7 for Ginger Bread (2.3.3)
Get the zip, and GApps if necessary
Place it on the root directory so it will be easy to locate
Go into your contacts and export them to your SD Card
Boot into Recovery
Wipe Data, Wipe Cache, go to Advanced then Wipe Dalvik Cache
Go to Mounts and Storage, Format System, then Mount System
Install zip from sd card, choose zip from sd card, select and let it run (repeat for Gapps if necessary)
Reboot

Actually it is possible to install cm7 over 2.3.3 you just have to use the unofficial cm7 on rootzwiki
Sent from my Droid Incredible using xda premium

So pretty much, I can just flash any of these ROMs the same way I did Apex (in recovery, wipe the data and cache and then install .zip for ROM and gapps) so long as I'm running the right OS/have the right kernel? I noticed on rootzwiki that there is actually a version of CM9 up, could I do that the same way too?
Just some info in case it's needed:
System Version: 4.5.153.A955-continuous.Verizon.en.US
Android Version: 2.3.3
Baseband Version: BP_C_01.09.13P
Kernel Version: 2.6.32.9-gca08d89

Yes, you can flash CM7/9, MIUI, Gummy, etc as you did before. Just make sure if you flash any actual 4.0 roms such as CM9/MIUI V4 you format and then re-mount system. There are slight differences in GB and ICS that apparently necessitate this because anyone who has skipped this step has ended up having to SBF back to GB and start over.

Perfect, thanks. One last question for now though (I'll flash later today): will the data I'm saving on Titanium Backup transfer over to an ICS rom? I'm saving my messaging data and some data for games, and I'm not sure whether they are applicable on the new OS.

As far as I know yes, that will work with TB, but you also might want to download an SMS backup app from the Play Store quickly just in case.

Just wanted to say thanks to MissionImprobable and Albinoman for their help--I'm successfully running CM9 on my Droid 2!

[Q] installing new slim bean rom on SGH-I337M

I am currently using a another custom rom on S4 SGH-I337M.
I would like to install the Slim Bean 2 stable rom on to it.
I am very new the installing roms etc,. Just rooted and installed CWM on my phone last week.
My question is do I doing the following procedure to install
5.Now, perform data wiping task. To do so, select wipe data/factory reset, then select Yes on next screen to confirm your action. Wait few minutes till the data wipe is complete. Now come back to CWM recovery main menu. Select wipe cache partition and after wiping process done, select Wipe Dalvik Cache under advance option to perform Dalvik cache wiping.
Or follow the guide on Slim Bean sire:-
SlimBean 4.3 installation instructions
After there is a some confusion about how to install 4.3, here is a list of what's absolutely necessary
■full wipe (means: wipe data / factory reset and format /system)
■install Slim 4.3 ROM
■install Slim 4.3 gapps
■Reboot
What is the difference between the two guides.
As I mentione I have been doing quite a bit of reading and I was able to following the instruction when i first rooted to install custom Rom my phone. But is a little confusing with so much out there to read.
Thanks in advance for any help and suggestions.

Okay dude I was a noob too just a few weeks ago and I was staying over the little things too. Basically the only things you need to wipe are cache and dalvik cache and format/data but beware you should always have a backup of your current Rom because wiping data will make your phone unable to boot incase the zip file you downloaded doesn't install. In that case you can simply restore your rom download anther and try again so yeah
Sent from my SGH-I337M using xda app-developers app

There's no real difference between those 2 guides.
Slim ROMs always recommend manually formatting system (as well as wiping cache / dalvik / data) but in theory it shouldn't be necessary. As you flash a ROM if you watch all the text on your screen you'll see that it formats the system itself. When you do a data wipe / factory reset you'll notice that it also wipes the cache at the same time. There's no harm doing it twice and I usually end up doing more than necessary.
As the previous poster said, ALWAYS make a backup before you do anything serious. My backups consist of:
- nandroid backup (with CWM or TWRP)
- back up all user apps and data (never system apps/data) with Titanium Backup Pro (I actually do these 3x/wk on a schedule)
- backup Calls and Messages to xml with TiBu Pro
Whenever I change from one custom ROM to another (say, Cyanogenmod to Slim) or one Android version to another (4.3 to 4.4) I do all of the following...
- wipe data / factory reset
- wipe cache
- wipe dalvik
- mount system
- format system
- flash ROM
- flash GAPPS
- with Kit Kat (Android 4.4) I've also been flashing SuperSU1.69.zip since some of the early Kit Kat ROMs were breaking Superuser.
- reboot
- follow the basic setup procedures to get your main Google account going
- open Play Store and get TiBu and Pro Key again
- open TiBu and do a batch action: "restore missing apps with data", then restore calls and messages from xml
- go into settings and tweak away......
When I update to a new version of my current ROM (like a new nightly or weekly or new stable version) I do the following...
- wipe cache
- wipe dalvik
- flash ROM
- flash GAPPs
- reboot
This is a "dirty flash" and can cause problems so do it at your own risk. Worst case scenario is that you might have to restore your backup or do a proper full wipe and try again...

I should also mention, if you've already taken a stock phone and followed instructions to root and get a ROM going then what you're trying to do now is even easier. As long as you have CWM and make a backup you don't need to worry. Just make sure you always download the correct version of the ROM for your phone as well as the correct GAPPS package for the Android version you're flashing.

[Q] Restore widgets/screen/folders/layout/etc

Just as title states, I always spend a lot of time after restoring apps and data from flashing a new ROM getting my screen and layout and folders and widgets as they were prior to flashing a new ROM.
Is there a way to restore all this quickly?

NO
The problem you're having is when you install a different ROM you usually "Wipe" everything. If you don't wipe /data then everything you have is still there. However you will have problems going from one custom ROM to another, as each developer has made some tweaks to the system packages.
Generally speaking, if you are running a "Stock Odexed" ROM you could possibly dirty flash a "Custom Odexed" ROM.
Same goes for Deodexed to Deodexed. You will have problems if you try to cross dirty flash a ROM.
So the simple answer to your question is NO there is no easy way, even if you backed up your Applications using a tool like Titanium Back Up.
If you are just updating the same ROM, the developer will say to either Clean Flash (wipe everything) or Dirty Flash (IMO still wipe cache and dalvik). If you can dirty flash everything will still be just as you set it up.

Got everything restored already, I'll have to just suck it up then I guess.
Just makes me wonder how flashaholics do it.

A couple of questions before installing CloudyG2 3.3 Rom

Just before harming my phone because of any potential ignorance, I wanna ask: If I'm on LG G2 (D802) with a rooted stock LP + TWRP v2.6.8.1 which I've installed via an app called "AutoRec". Does that imply I've KK bootloader and ready to flash the zip file of Cloudy? Also will I get app notification badges with this ROM right out of the box?
Thank you in advance!

You are safe to flash, go ahead.
Not sure about your 2nd question, sorry.

i'd suggest to update your twrp to at least 2.8.7.3 just to be on the safe side...
autorec installs an older twrp version by default
you can update twrp just by simple flashing the newer version
1. download the newer twrp for your device variant
2. enter twrp
3. flash newer twrp
4. reboot to recovery
if everything went ok, twrp will show you the newer twrp version in the top left corner
now you can flash the rom
btw app notification badges are not present in any stock based rom such as cloudy...
you can have that option by using an app like Tesla unread in combination with Nova launcher

Thanks for your inputs Andeby & 60nine!
@60nine
In fact, I flashed before I've seen your post but it's good to update the TWRP anyways. I think I've seen v3.0.0 somewhere but I'm not sure...
I've seen badges for FB so I think badges are working OK with this ROM out of the box.
I'm still teased about the "Accounts & Sync" page since it doesn't allow me to selectively choose which accounts to sync or not sync as I've seen in different screenshots that came from different skins. In LG's skin, It's either sync all or sync none which is a bad implementation in my opinion and I really wished they've addressed this in the 2 official updates they pushed to me (KK & LP) but now I don't have any faith that they 'll push any "M" update, not to mention that sync setting I'm annoyed about so I'll have to live with what I've until I get a new phone (hopefully it'll be the 5.5 inch version of the coming Nexus, if it'll have that e-sim technology :fingers-crossed
P.S. I'm not sure why LG implemented the selective sync feature in some of their older mobiles but not the recent ones!!! (as I've seen in the screenshot in this thread http://android.stackexchange.com/questions/55728/how-can-i-select-the-apps-to-sync-when-auto-sync-is-turned-on)

about selective sync
some apps allow you to turn the sync off (i.e. soundcloud that i use)
google on the other hand has the selective sync that you can turn on/off for each google feature (calendar, gmail, fitness, contacts...)
it's accesible when you enter "accounts & sync" in settings, then choose "google" and click on your google account email address...
i think that's the lollipop and per app thing, not LG specific...
about twrp version
2.8.7.3 is confirmed almost 100% stable and working with all latest roms...
latest version is 3.0.0.-4, but it's still in development (although it works just fine for me since i flashed it)
also - make sure you're using blastsgator's twrp

Thanks for all the info. I'm just not sure about the last line you said about using Blastsgator's twrp. Is this some person's name who modified twrp? I installed my twrp via autorec because the twrp manager app didn't work for me for some reason so I'm not sure how to update twrp other than installing a newer version of autorec (if there's such one) that will update the twrp for me i guess

blastagator is the developer - autorec uses his twrp (although the older version)
twrp download page - http://www.gregtwallace.com/lgg2-projects/twrp/
xda thread - http://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705
to update twrp
- simply flash newer version via twrp itself
- reboot to recovery (not to system)
- check if the newer version is displayed in the top left corner
- continue with your flashing or whatever you want
also, make sure you download the proper variant of twrp which suits your model (i.e. d802)

Thanks for the great information!
Just one more question: In the TWRP manager, Install, I have options to select these:
Backup: No
Wipe Data
Wipe Cache
Wipe Dalvik
For the last 3 wipes, are they talking about wiping the old recovery itself if I wanna wipe it before installing a newer TWRP version? Is it the same for backup (i.e. if I wanna backup the older TWRP version)? I"m a little worried that these options have something to do with the ROM itself (system) I'm currently on!
What I'm planning to do is to leave these options unchecked & add the zip file I downloaded from the internet, then hit "Flash Now" OR it's best to wipe the old recovery first before installing the newer one? (similar to clean flashing a newer ROM).

i'd stongly advise you to use flashing directly from the recovery itself - not from twrp manager...
to do that:
1. copy your rom zip to the sd card (internal memory) somewhere - i.e. in the root of it
2. reboot to recovery (twrp)
3. choose wipe > advanced wipe
4. select wipe for system, cache & dalvik (DO NOT select internal memory because it will wipe your internal SD card where you've put the new rom zip)
- you can also choose "data" if you want a full clean install (just make a backup of your data - to your PC or something)
5. go to recovery homepage and select "install"
6. choose the rom zip from your internal memory
7. press install/flash
8. aroma installer of the Cloudy3.3 rom should pop up - follow the instructions
9. choose your device variant (in your case it's d802 if i remember well)
10. choose those additional options to your liking (no need for removing LG cover app for xposed to work properly - it's been fixed in xposed itself since then)
11. when the rom installs - you can reboot your device
first boot will take some time - sometimes you'll see just a LG logo and flashing leds for as long as 5 minutes until the "android is upgrading" screen popup appears...
good luck...

wipes explanation
- wipe system - wipes the old system partition (i.e. old rom files you had)
- wipe dalvik - wipes the dalvik cache for apps
- wipe cache - wipes the system cache
- wipe internal memory - wipes the devices sd card where all your private files are (if you wipe that one - you will lose your images, music, etc. - and there is no way to get them back after you do this)
- wipe data - wipes the personal data (contacts, phone log, messages,...)
most common wipes are
- system, dalvik & cache (when you want to keep your personal data & files)
- system, dalvik, cache, data (when you want a completely clean install)
- system, dalvik, cache, data, internal memory (same as above, but do that ONLY if you're installing your new rom from usb/otg stick, not from internal memory)

but I've cloudy3.3 already installed and everything in it have been set up (settings, software...et) and I'm pretty satisfied with it as it is much more useful than original stock ROM. What I'm talking about is updating the recovery manager itself (TWRP) from the older version I have (2.8.6.1) to the newer version (2.8.7.3). I assume that it's possible to update to the newer one without any harm to the system currently installed. Right?

oh, sorry then...
then just do this
1. put new 2.8.7.3. twrp file somewhere on internal memory
2. reboot to recovery
3. press install
4. choose the new 2.8.7.3. zip
5. press install/flash
6. after the flash is over - choose "reboot to recovery/twrp" to see if everything went ok
7. if everything went ok - reboot to rom
no need for any wipes

Never mind! Thanks for all the valuable info
