hello guys, i want to downgrade because i am sick of 4.2.1. Due to the fact that i have a 8gb nexus 7(rooted) i am having memory shrtages and directorybind dont work on the latest version...so i have a few questions:
can i downgrade without losing data?if no....how do i backup my apps and dara
should i downgrade with wugs toolkit?
If it's not obvious already: you'll need to do a clean-wipe to downgrade. Just flash the appropriate gapps and you should be good to go. Keep in mind any custom kernels/zips you may have flashed that may not work on 4.1.2. -Use Titanium Backup to backup your user apps as some 4.2 system apps won't work on 4.1.2
Have you tried other 4.2 roms or different kernels? I used to get horrible battery drain and some performance issues with the stock rom and kernel, then I tried other options and got much better results

Please try a custom rom before all hope is lost. Try Rootbox
first of all i have never flashed a custom rom or kernel
secondly if i backup all my games and apps with TB when i restore it in 4,1,2 will it work properly?....as i have seen people complaining that after restoring they were stuck in bootloop...
...is there any custom roms that support directory bind or any other ways that allow playing games from usb stick?

what are GAPPS?
where can i find the appropriate gapps for 4.1.2?
can i use these steps to downgrade : http://www.ibtimes.co.uk/articles/4...-stock-android412-android42-jellybean-ota.htm
This is what I would do:
Backup your desired apps using Titanium Backup
Install the factory 4.1.2 image using the instructions here
Root your device and restore the apps using TB
I don't know about bootloops caused by TB, but if it does you can reflash using the guide in the list.

You don't flash gapps on stock...
And we have a sticky thread for doing this; no need to leave the forum.

Hi !
We all are very anxious about the upcoming official JB rom. But, how to be prepared to it, how to lose (almost) nothing in the process, how to do it ?
Which method do you guys recommend ?
1) Apps / data backup
- Google automatic backup :
it seems to be able to restore apps/data/settings, but will it work with a major update like ICS->JB ?
- Titanium backup :
Recommended method
the fastest and easiest way to restore apps is to use titanium backup, your ICS backups will work fine on Jellybean, moreover your progress in games etc. will be restored as well
And, how to restore the backup without root ?
Not possible !
download CF- Root 6.4 stock kernel and flash it via Odin
- Kies backup
This is XDA we dont use KIES
- will internal SD be wiped during the process ? Do I need to manual backup my games very large data for an example ?
your internal data won't be wiped so don't worry about app caches
2) The update process
- with Kies
This is XDA we dont use KIES
- with OTA
NO it will fail due to root
- with Odin
recommended method
As soon as official firmware comes out you will be able to flash it
- with CWM
wait several hours after release for someone to post a CWM zip of firmware which to your happiness will already be rooted , so no need to flash CF kernels
Other questions :
- is there already a known method to root ?
download CF- Root 6.4 stock kernel and flash it via Odin
- will I lose my 48gb Samsung Dropbox bonus ?
- if needed, where to best pick up the update file ? Sammobile ?
Standard XDA method
- Backup apps with Titanium
- Make a Nandroid backup of ICS
- Flash stock rom from XDA via Odin when released root
- Restore TB backup
On my old nexus one, I usually make a Titanium backup, flash the new already rooted rom, install Titanium and restore the backup.
I know it is a lot of questions, but I really want to upgrade without a pain. I'm used to flash, but that's the first time I really care about backups... 16gb is really a lot of data.
Thank you...

Wow ! That's a really fast reply for the dangerous part. Many thanks.
Could I use your informations to update the first post ?
Firstly, your internal data won't be wiped so don't worry about app caches . Secondly, the fastest and easiest way to restore apps is to use titanium backup, your ics backups will work fine on Jellybean, moreover your progress in games etc. will be restored as well. Yes , you will have to root , but it takes you 2 minutes to donload CF- Root 6.4 stock kernel and flash it via Odin- that's all, you're rooted and able to use TBackup .
Regarding an update method . As soon as official firmware comes out you will be able to flash it via Odin(can be found in development section) , but as you prefer CWM method just wait several hours after release for someone to post a CWM zip of firmware which to your happiness will already be rooted , so no need to flash CF kernels

I read that cf-6.4 is indeed OTA compatible. Wouldn't uninstalling busybox and su allow to do the OTA?

I'm not anxious at all.
What is the problem with KIES?
You keep all of your data/apps/settings then re-root and refreeze/install apps you want gone in titanium. Very simple! I have done this for two of the past three updates.
OTA may fail with CF-root. I guess we will have to wait and see whether it works when JB arrives, I suspect it will fail though.

Hi there, i'm new to android OS all together, I've recently started using android and manage to root my phone along with the installation of franco custom kernel.
I'm looking to update to the latest 4.2, but I can't seems to find a proper guide to do that.
1. For custom ROM, you have to flash it to stock rom before you are able to upgrade is that right?
2. What about custom kernel, do I need to do the same?
3. What is the best way to backup my data for an upgrade? Nandroid backup or the one in titanium backup (app + data) would be sufficient?
4. could anyone provide me a step by step guide on what needs to be done (i've downloaded the file for 4.2 build).
many thanks!
anyone could help me please?

Can u tell me what your's phone model?
Look for Wug's Nexus Root Toolkit in development thread. Read the threads and instructions carefully before flashing the firmware you've downloaded under flash stock + unroot. Just follow the instructions step by step. Once done you need to root it using the same toolkit. NOTE : THIS WILL WIPE EVERYTHING! And you will have 4.2 and stock kernel.
You will need titanium backup to restore data and apps. Nandroid will only let you go back to same ROM before.

I'm using Nexus 7.
Thx for the reply, so you're saying in order to upgrade the OS i will have to 'reset to factory setting' as in unroot it and lock the bootloader?
Do I have to flash it with original kernel as well?
No.
Reset to factory only wipe all your data (user data). It won't unroot or lock boot loader.
Refer to my previous post. I find it to be easiest to do with a toolkit. Just search it, it's a sticky in Android Development section. You don't need to unroot first, just flash using the toolkit, it will do everything for you. Of course read the thread first.

N4 is my 2nd Android phone (my 1st is an old HTC Magic) and have never rooted a device before.
I'd like to install PA. So do I need to root it first?
Also I have already installed some apps, I'd like to do backup before factory reset. What is the easiest way for this?
Thank you

Firstly Install carbon backup app (like titanium backup) from the play store to backup your app and app data. It is good because you don't need to root your device in order to backup.
However in order to root, you need to unlock the bootloader which will delete everything from your phone. After that it is easy to root your phone using the guides in the forum. I suggest you don't use toolkit if you want to learn how everything works.
Only after rooting, you can install PA.

You don't need to root. Open boot loader, install custom recovery preferably twrp and you can install the zip files you need. Roms come rooted by default you don't need to worry about that.
i think root will make it easy to install app

Thanks moles. I didn't know that you didn't need to be rooted to your roms. I guess you learn something new everyday. Btw I love your PA roms. This is my first android device and PA is the only ROM I've ever flash. Keep the good work.

There is a flashable ota at the link below. You may need to flash superuser 1.51 after to get root back.

OK I tried that but I got a Status 7 error message and it aborted install. I have everything stock that I can think of. No custom kernel. No nothing. Any suggestions other than flashing back to stock completely via Wug's toolkit then doing the OTA through the tablet itself and then restoring everything with Titanium Backup?

If you check that thread I linked to above, there a few people with the status 7 error and a few different fixes, worth a try before wiping anything, hope it helps.

You don't need to flash the stock image and lose your data, but even if you are on stock 4.3 you still need two things: stock recovery (if you don't already have it installed) AND you need to unroot! Being rooted will throw the Status 7 error.
Here's what I did:
First flash the stock recovery for JWR66V in fastboot.
Then use the "Full unroot" option inside SuperSU.
Apply the JWR66Y update using ADB sideload.
Then reinstall TWRP and install UPDATE-SuperSU-v1.51.zip using TWRP.
After rebooting you may be surprised to see that the SuperSU app needs to be installed again (seems to be a quirk a lot of us are having). Just head over to Google play and after that all should be good.

Hi, I'm looking forward to doing this step since I really want to get that OTA installed in my device. Mine is on stock ROM, rooted via wugfresh toolkit. My concern is, after doing this step, will I lose all data? Also could you please explain how to do the first step- "First flash the stock recovery for JWR66V in fastboot."? I'm still a bit new to all these things, so please bare with me.
Thanks!

Check out this thread. I flashed the Grouper.zip file, which is the OTA modified by commenting out the validation check that results in the Status 7 error. I copied it to /sdcard along with the Supersu 1.51 zip. The ota flashed perfectly using TWRP recovery. After booting and going back into TWRP, I flashed the supersu1.51 and regained root. You do not need to unroot or flash stock recovery to get this update. No data loss. I'm stock rom & kernel, rooted with TWRP recovery.

You won't lose data if you repeat the steps I took. However since you are asking how to flash a recovery in fastboot I would seriously be careful and do a bit of homework on how fastboot works. All the instructions you'll ever need can be found by searching xda. It really isn't as daunting as it sounds but you definitely need to understand how it works before trying it.
Or you could try the link that Groid posted if you aren't concerned about skipping the validation check. The process is definitely is simpler if you're "new to all these things".
I'm not opposed to using WugFresh's toolkit, he's a brilliant developer, but it's never a bad idea to learn about what happens in the background and see it with your own eyes.

Hi, jjdicecco...
If you have a Nexus 7 with a Custom ROM (such as AOKP) installed on it, you won't be able to update it to stock Android 4.4 KitKat via the normal process of OTA updates.
Googles OTA updates do not work with Custom ROMs - only with Unmodified Stock
The reason why, is because OTA's aren't full ROMs - they consist of a collection of 'patches' that are applied (during the update process) to the system files in the preexisting version of official stock Android. But before those 'patches' can be applied, the OTA runs a checksum on all system files to ensure they haven't been modified... and a Custom ROM such as AOKP, represents a very significant modification of stock Android... so, in short, the OTA will abort with no changes made.
The only way to bring your AOKP Nexus 7 up to date with KitKat, is to forget about OTA's and flash the full factory image for Android 4.4 KitKat, available here. Essentially, you need to re-install the entire Android OS from scratch.
It's important you download the correct factory image for your specific Nexus 7... so if your Nexus 7 is WiFi only, you'll need the 'nakasi' image... if it's the WiFi & 3G model, then the 'nakasig' image is required.
Although there are toolkits that will get the job done (so to speak), I've never used them myself... and IMHO, you'd be better of using the fastboot tool that Google themselves provide.
There is an excellent tutorial available here on how to use fastboot to flash a factory image on the Nexus 7.
It looks a little daunting, but if, as you say, you're no stranger to rooting or flashing recoveries such as TWRP, then you shouldn't have much problem following it - it's actually quite straightforward.
Hope this helps... and good luck.
Rgrds,
Ged.

Yes, you can.
If you have TWRP installed, just download the ROM .zip of your choice directly to the Nexus 7... boot into TWRP, go to WIPE>ADVANCED WIPE and clear Dalvik Cache, System, Cache and Data... BUT UNDER NO CIRCUMSTANCES, WIPE INTERNAL STORAGE... or you'll lose the Custom ROM you just downloaded. You'll have no bootable OS, and no easy means of installing one... without resort to either ADB or fastboot.
After this, use the INSTALL button in TWRP to flash that ROM. (You'll need to navigate to where it downloaded to - usually the /download folder on the Nexus 7's internal storage).
It's a good idea, though, before doing any of this, to perform a NANDROID backup of your current AOKP system using the BACKUP button in TWRP... just in case anything goes wrong with your ROM flash, or if the ROM you flashed isn't what you expected it be.
You'll then have an easy way of getting back to your current setup.
Rgrds,
Ged.
