Hey, i am new to root and all. Can anyone tell me if i will be getting any software update from manufacturer if i root the phone ??

Root requires unlocking bootloader, so any manufacturer update will brick phone.

[Q] re-gaining root after update

Hi
I know that's propably a noob question but I forgot to install rootkeeper before I updatet to .21 firmware (europe), now my root is gone (at least that's what I think cause when I type in terminal emulator su, I get a permission denied error...)
I rooted my prime with sparkyroot app.
my question is: can I re-root my prime (with the same method) without getting bricked or anything like that?
From what I have read, there is no root method for .21 yet, just feel fortunate my tablet got hosed by the update entirely and I had not unlocked the bootloader so I am at the mercy of asus
Unless you want to unlock your bootloader and lose future OTA's and your warranty, there's no way to root .21 until they find a new exploit just have to wait
Hi all,
Prime Transformer using Asus for a month. Detail the issues which the forum for a while and looked, I tried some of the root methods. Authorities, however, and 9.4.2.21 update lost. I am writing this message I can think of something to consult.
Pending the development of a new method, like helping a friend with OTA Root Keeper backups can tell us where can we solve this problem?
For example, you share with us to take backups of AppBackup Rootkeeper OTA with the application?
Best regards from Türkiye.

There is currently no root for .21 update.
But, you can unlock the bootloader and flash a ROM that is already rooted, which will give you root. But that will void your warranty (by unlocking the bootloader).
you can downgrade using http://forum.xda-developers.com/showthread.php?p=23872834 but the question is :
after rooting old version, is it possible to upgrade to .21 keeping to root mode ??
yes, you downgrade (I went to .14 because it was the only one I could find) then you root, then you download and install ota rootkeeper from the market. Then you go back up to .21 and believe me this is a complete oversimplification of the process.
DO NOT UNLOCK YOUR BOOTLOADER JUST FOR ROOT
What I want to root on .21, I must say that I am very happy that I did not unlock my boot loader. Last week I had to send my TFP with dock back to Asus as it would never charge the tablet when connected to the dock. Therefore, they quasi upgraded me from a tfp201-pad 0214 to the 0215.

Keeping Root?

I have a unlockable bootloader Xperia S, but for warranty & DRM key reasons, I am currently refraining from unlocking the bootloader. I have however rooted it.
My question is, can I keep root using OTA Root Keeper, so when OTA updates arrives root stays?
You should be able to.

Update Via PC Companion not working

Hello all.
I need some help how to update the z2 to lollipop.
I've read stuff on internet, but I simply can not do it.
The error 2003 is killing me... And I do not know what to do.
A month ago I bought a z2 for my brother and it was/is on kitkat.
Today, I bought a z2 for my father and there was lollipop already installed.
I bought both phones via Ebay.
The phones have the same Model Number.
On the kitkat z2 I cant update via OTA either.
Could you PLEASE tell me what to do?
I have read something, that my bootloader may be unlocked and I have to relock it.
Is that true? And if yes, how can I check if my bootloader is locked?
Thanks in advance!
Use flashtool to flash a stock FTF image, this way you won`t have to bother with the bootloader, unlocked or not.
If the phone is rooted OTA updates won`t work., it will say it can`t verify. And it`s true that unlocking the bootloader will cause OTA updates to stop working.

I wanna root, shall I update software?

Hello, so currently I m on H90120J and I keep getting notification to update software, but since H901 is a bit strange with rooting I m not sure if I should update.
Currently my bootloader is unlocked but I can't install two. I need to investigate on how can I achieve that since fastboot Command returns error when I try to install TWRP 3.
there are a tutorial in xda forum about how to do root. and after doing root it doesn't matter if you have latest update installed before rooting or not.
cheers
