[Q] Kitkat Update - After Root

[Nishantjoshi]

Hi-

I have rooted my device. Bootloader unlocked. Now my doubt is:

1. If I will still receive Kitkat update from Sony?
2. Can I be able to just download the same and install?
3. If yes, what will happen to my root?

Regards

Yes you will get a notification that an update is available, but your phone wont be able to install it (since bootloader is unlocked).

Thus, to apply the update, you need flash the stock firmware via flashtool.

And yeah, you'll lose root access once you flash the firmware. Just flash su binary via recovery to get it back.

Hope this helps.

Thanks @sohailferdous.... but I have few doubts - 1. I know the process of flashing a firmware via flashtool....but for that your need the ftf file...so is there a way to get the stock ftf file? Because .253 ftf india is still not available. The one present is AUS version

2. When you say SU binary I take it that its the SU zip file which is present in Doomlord's root update.

1. The AUS version should work on all phones.
2. Yup, the SU zip file on Doomlord's root update will work fine.

Hi,

I have a T2 Ultra Dual (Chinese Version ... XM50h) flashed it with the Australian firmware. Works great and shows now as D5322. Today I read about Kitkat Update - I'd connected the phone to the PC Companion - Companion started to download the Kitkat Update but when it shutdown the phone to install the upgrade I got the message that there is a modified software on the phone - update can not continue (Error2003)

Is it possible to get a flashable file out of PC Companion?

No, u cant use pc companion until n unless you relock your bootloader, try flashtool as an alternative.

Strange - bootloader should be locked - how can I check if it is locked/unlocked?

When I try to flash 4.4.2 unbranded firmware from Ashwin - flashtool stops after the bootcode and nothing happens. Flash failed (so says the phone after rebooting. PC Companion repair does not work.

Reflash of the Australian 4.3 works - phone is up and running after 4.3 flash ...

Strange ...

Found a solution by myself!

Downloaded recent Flashtool (0.9.16)
Clicked on BLU
relocked bootloader (I had forgotten that it was unlocked)
Rebooted the phone
Started PC Companion
Update to 4.4.2
Sucess
