[Q] How to uninstall a CROM and update officially again? - Acer Iconia A500

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

You can flash stock room with root but you will not be able to install ota. You would have to go stock without root for it to update via ota

[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

Samsung update for rooted phone?

Hi guys,
Been a while since I posted here. Bought my phone 910c brand new when it came out and just rooted it so I could modify the DPI. I still have the stock rom etc as I prefer to have stability.
Now I'm sort of getting bored still on KitKat and want to update the firmware.
First step I took was to make the phone "official" in wanam and then download the update ota. This didn't work as there was an android with belly open and triangle.
Now I'm thinking I will update via Pc Samsung kies. Will this work? And will I still have root access to change the DPI or do I need to reroot afterwards?
Thanks.
Updated via kies last night then had to root again.
Does anyone know how I can change the DPI for the stock apps back to 640?
Since I'm on stock rom xposed is not recommended for marshmallow?
One sure and safe way to update your firmware is via PC Odin. Just download your official firmware from Samfirmware website. MM is best in my opinion.
You can root your phone afterwards and install Xposed by Wanam, not the official Xposed zip file.

Official OTA update on a rooted device...

...first things first - xt1625, build number-MPJ24.13964.
I wanna update this puppy to Nougat, but can’t seem to find a stable custom ROM. Can I flash the official firmware release? I’m assuming I’ll lose root access. Anyone point me towards a stable ROM?
I wouldn't do OTA. Don't know why I put that, I'd dl and flash from recovery
