[Q] How to uninstall a CROM and update officially again?

Hello people. I'm with Taboonay ROM, but I want to reinstall the official version again and update to official ICS.
How can I do it? And how can I root the official ICS?

Just flash a stock rom available, and unroot your tab. Than you can update to ICS.
OK, let me tell, download an official 3.2 stock rom from http://forum.xda-developers.com/showthread.php?t=1429199
Flash this rom and you will be without root access, so no need to unroot your tab.
Now you need to upgrade to ICS which you can do easily using upgrade from settings or Acer Update Enhancer Application available in market.
Now for again getting the root access recommend the thread http://forum.xda-developers.com/showthread.php?t=1546593
Finally thanks the original Developers for there support.

Hmm, strange. I tried to install a stock rom and update it, but it was saying that there wasn't update. I'll try your way. Thanks.

how was it now? are you able to go back to stock rom and update officially? please share your result, if you dont mind

[Q] S5 official update to rooted device with official rom

Hi,
On my S5 (SM-G900FQ) , there is original Samsung ROM (4.4.2) , rooted but with default Recovery.
I want to update to new official rom (Lolipop) and then re-root.
What is the most easiest and convenient way to achieve this ?
I can update to Lolipop rom through Odin. But then how can I get back root easily ? (without installing CWM if possible)
If I have to install CWM, which version should I use ?
Thanks.

I'd appreciate any help. There are lots of threads talking about root'ing but I couldn't find the one which works for Lolipop official ROM.

Newbie requesting help to upgrade from 4.2.2 to Lollipop

Hello,
I have a rooted i337 with MDL baseband, running stock 4.2.2 firmware. I am currently out of the US and therefore cannot receive any OTA. I want to upgrade to Lollipop or Marshmallow based custom ROMs, esp those that can still use the IR feature of the S4.
Can anyone guide me on how I do this upgrade, without bricking my phone? Would truly appreciate your help. Thanks.

Have you tried running ota updates via wifi without a SIM card in the phone.
To run a custom rom, you would need to install a custom recovery to flash the rom. Some mm and LP ROMs may not work with a 4.2.2 modem and bootloader.

If you want to use a custom ROM, DO NOT take any OTA updates. If you take an OTA and it is successful, then you will no longer be able to install a custom ROM.
Here is the Cyanogenmod thread to install CM to your phone: http://forum.xda-developers.com/showthread.php?t=3008609
If you would like to update to official ATT/Samsung lollipop(there is also a way to have root)[remember, once you take an official update from MDL, then you will no longer be able to install a custom ROM and you may never be able to get Marshmallow]: http://forum.xda-developers.com/showthread.php?t=2926642

[Q] Revert to Lollipop

Hey guys...
I have been running the official 3.0 beta for a week and now I want to revert to 2.2.1.
I know I have to downgrade TWRP (right?) but I find the posts a little clttered som I need a straight answer.
What do I need to go back? I would like to keep a modded recovery and I intend to root it afterwards.

just follow this tutorial and flash back your 2.2.1 rom and then flash SuperSU to root it

I read that one but I´m unsure that the recovery is a modded one (TWRP)... cause I wanna keep that. But from what I understand I have to flash an older TWRP for Lollipop?
Edit: Nevermind... I got it. Now I just have to find the Stock 2.2.1

How to root and install custom roms easily?

I just bought a secondhand s10+ exynos. I wanted to root and install custom roms on it but all the solution i found is complicated. Id there any way to root this and install twrp without downloading the firmware? Thanks jn advance

I would say that you can use the TWRP guide to install the recovery and then continue to install a custom rom or using Thunderstorm Kernel if you want to use the stock rom.
You still need to unlock the bootloader but it is the only solution i know so far.
