I'm currently using a custom ROM and it's possible to access internal storage via TWRP
So I want to install a stock rom without twrp and root it. Is it possible to update then phone manually afterwards without losing data? Thx
Best regards
I don't think it's possible, don't install the update then but your phone will become slower.

I am not sure if my question will make much sense. I know how to flash official firmwares, and also how to flash custom ROMs via CWM.
I have been running 4.0.A.2.368 (UK Generic) for a while now, with [email protected] #3 kernel and of course root. I did this because for the time being I wanted an experience as close to the original as possible, but with added advantages.
I now want to update to 4.0.2.A.0.42, but without
a) Formatting my internal memory and thus losing my game installations and applications (a lot of which were purchased from the Store)
b) Losing root access
I know I am supposed to flash 4.0.2.A.0.42 via Flashtool, but I wonder if this will wipe the memory and thus cause me to lose above mentioned data.
Is there any way to update without losing my data, files, installed applications and games?
Many thanks for the help in advance.
You can flash via flashtool and still keep user data.
Also flashing new roms via CWM is not a good idea, there is no way atm to flash basebands (radio) via recovery so you would be stuck with older baseband.

Great! As about root.. Do I simply re-root the device?
I don't suppose I have to re-lock the bootloader to update via Flashtool, right?

Just make sure you untick the box that says "wipe user data". You can use flashtool with an unlocked bootloader. And as you have an unlocked bootloader, you can re-root by either flashing doomlords kernel, or by flashing the rootedupdate.zip in binarys CWM thread

I have a noob question:
I unlocked my bootloader and rooted my gsm nexus. However I would like to be able to receive and install any updates OTA- basically stay as stock as possible with root. My plan was to leave the stock recovery in place. If I need to do a backup or reflash su.zip (after an update to regain root) I was planning on running rom manager and using it to flash CWM. I realize that this CWM would not survive a reboot as the startup script will reflash the stock recovery.
Will this work and does it make sense?
thanks
quick bump- basically I want to know what will prevent an OTA update from installing
Edit I realized there was a flaw in my logic. After an OTA update I will lose root and then be unable to flash the recovery via rom manager. I guess will have to resort to fastboot after OTA
Hello,
I have read somewhere that is possible to install TWRP without the need to have root access before installing TWRP. Just a simple flash with ODIN should do the trick. Has anyone tried this on the note 2014?

of course you can do that.
TWRP is used to manage ROMs and BACKUPs, it had no effect to your installed rom.
but it will trip your knox flag like rooting does.
you can also root without installing TWRP.
I'm currently STILL stuck with V10a-EUR-XX on my unbranded, non-rooted G3.
If I were to manually update it with a downloaded ROM, would I lose all my apps and their data?
Should I root, backup with titanium, then update and re-root?
Which tool should I use to flash the update that gives the best chances of maintaining data?
thanks!
Hello community,
I wanted to download the new lollipop update, but the OTA fails. The reason is: I unlocked the bootloader (without root).
What is the fastest way to update to 5.1? Is there any way, keeping my data?
If not, what is the best way to backup these data?
Thanks for your response!
Do you have root and a custom recovery? Then you flash a pre-rooted ZIP without wiping your data.
You could also do a nandroid backup priop to this in the recovery.
Otherwise, you may want to root your 5.0.2 and then install the custom recovery.
I am not sure if full backups without root are currently possible.
Thanks for your reply. It helped me a lot.
I want to describe my solution shortly:
1. I used this describtion for obtaining root http://forum.xda-developers.com/son...root-init-d-support-recovery-busybox-t3202799
2. I did a backup with CWM
3. I did a dirty flash with this describtion: http://forum.xda-developers.com/son...6-0-368-customized-lollipop-5-t3200948/page11
So i got Recovery + root + 5.1 without loosing data.
