[Q] Do updating phone trough flashing firmware wipe it? - Galaxy S6 Q&A, Help & Troubleshooting

Hi
As my phone is rooted, I can't update phone through OTA.
There just came a new firmware on Sammobile (May 21) and I downloaded it. If I flash it, will my phone be wiped?
Also, if it do. Is there anything "to do" so I can get everything with it?
Thanks in advance

No, unless you select wipe in odin

Also you can flash a stock recovery in twrp and then unroot.

[Q] Stuck at Google logo!

Hi!
I rooted my Nexus few months back from now with Fastboot recovery. I got my Android ICS update 4.0.4 last week, I tried downloading it, I downloaded it, then it said rebooting for install. But my Nexus S freezes at Google logo with my unlocked lock sign. I have tried installing it many times, but all in vein.
Please somebody help!

If you're rooted, why dont you just use the rooted method to install the update. Someone made the update flashable. Its in the development section.
either way, pull the battery to see if you still have your recovery(volume up and power button)... if so, then restore to your latest restored point, hoping that you did make a backup
Then download the newest ICS update and just flash it the rooted way.
But if you insist on the official, unroot and then get the update via stock recovery method
good luck
Are you using the latest version of CWM?
If you've got a modified system image (including root), you should not use official upgrade packages. If you want to update the rooted system, you can use unofficial packages (in CWM). To boot a system, please start your recovery and flash a proper (4.0.4, unrooted or rooted, signed or unsigned) system image. If you erase the data partition all of your data is lost!
If you have stock recovery, then only signed images can be flashed. To be able to flash unsigned images you'll need CWM, which can be flashed through fastboot.
By the way official firmware can be downloaded from Google. Important! All of your data (including USB storage area) will be lost after the full upgrade with fastboot!

What happens if you get OTA on a rooted phone?

I heard the phone gets unrooted with an OTA? So what happens to the apps that need root access? They stay there and start working fine when you root again or need to be reinstalled?
Do you lose data in the process when you install OTA update on a rooted phone?
if i remember correctly , it will not have OTA with rooted phone even with stock ROM.
by root , you must have change some system file , most case, flash CWM recovery and install superuser, which will effectively fail the OTA.
You will get the ota.
it will install perfectly normal if you still have stock recovery.
if you have custom recovery manually flash the update.zip Then flash su.zip. You're now stock rooted.

I have stock recovery and I do have some third party apps installed as system apps but I havent deleted any.
I'll think unless I am one of the first to get OTA I'll prolly be too impatient to wait for it anyways and flash through CWM. But will I lose data flashing through CWM? I have flashed stock roms through stock recovery when it was allowed in GB and never lost data but I wasnt rooted back then.

Be patient, stay rooted, soon after the release I am sure there will be a stock rom that you can flash via CWM,
You won't loose data.
You can flash official updates through cwm no problem. In fact that was the only way to do it manually after 4.0.3. Stock recovery would not allow manually flashing the update zip. Would end up in a error 7.
So it was either wait for the update to be pushed to your phone or flash it manually with a custom recovery

People i know haven't even unlocked their bootloader
But can't update?
me too, have the same problem.
I'll just flash the 4.4.4 EU image for my XT1032...
and I'll do the same thing for when lollipop comes around
Its look like you must reset factory then direct updating your firmware..
have you unroot and relocked your bootloader?
Try restoring to stock: Flash 4.4.3, go to stock recovery and try to make the update search, if this is not working do a clean flash (wipe cache+userdata) and try to update, some time ago i noticed that cannot update the firmware of my 4.4.2 because the cmw recovery, then wiped cache and intalled stock recovery and everything went fine
To receive OTA updates device should be only on stock recovery no cmw, no twrp. Try to install stock recovery with fresh stock rom, and remember to enable any disabled system apps (if any) like Motorola services, Motorola OTA, then only you will able to receive and install updates....
You need the stock recovery

[Q] [D6643]How to downgrade from 23.4.A.1.232?

How to downgrade from this version?? i commited an error on upgrading it via OTA, and, i lost my root, XZRecovery and all.. i do the search on Z3/general but cant find anything talking about D6643.. only for the other models.. can someone help me!? :/
If you really need to downgrade, Google the rom u want, just flash it, and you're done, its always there in Google
When you have root and recovery you NEVER do an ota update!
What you can try:
Flash rootable firmware as you had before with flashtool, download it via xperifirm. Then root and install recovery. After that install the rom you have been on before ota. When you do this all and never wipe data partition, you maybe keep your files and apps.
When flashing rootable ftf you must uncheck data wipe. Dalvik and cache can be wiped. Once i did this on my z1 and z3 and it worked. Should work for you too because the whole xperia plattform works mostly the same.

Installing system update with TWRP

So I decided to update my phone ot the latest version, but since I have TWRP installed when I downloading the update it reboots to TWRP, thinks for a second and then goes to the main menu. Never does the install. Anyway I can go about installing it or do I need to install the stock recovery? If so does anyone have a link to the stock recovery.
You need to be stock (not rooted) to take updates. You'll have to flash the phone back to the original firmware, take the updates and then decide if you're going to reroot. BTW just unroot in will not trick the system. You need to have an untouched system partition. If you unroot you'll still have a marked system. Only ruu can undo it.
If you are s-off or unlocked bootloader then don't change them. It's not necessary. If you have manually locked or relocked your bootloader I recommend unlocking it before you flash the firmware to avoid any problems later on.
Find the ruu in zip format and go from there.
