Default 290 OTA available!

Hi guys, just thought I would inform you that the 290 OTA is out in the USA. I have a c6903 that was imported here, SO I do not know if the phone has a location set or if its just going by my carriers connectivity, which is StraightTalk.

Should I update OTA and see if it preserves root?

You can't do OTA if rooted. Sony has taken care of that. OTA will fail if you try.

I guess I should read the forums a bit better. Yes, the update did fail.

I thought sony sort of "encouraged" rooting.

Anyways, I wasted space on the forum.. =(

Strange beause it worked for me. I have C6903 unbranded (Romania).

I flashed 534, rooted, OTA-updated to 257 (root was kept)
Today I received the notification that an update to 290 is available.
So I successfully updated to 290 via OTA. Root is lost though

I did OTA update and root is survived but partial root only. System files are write protected. If you want fully working root, you need to unlock the bootloader (at least for now).

I removed root and couldn't update OTA. Had to resort to the pc companion. I hope this helps in the development of a solution to get a 4.3 OTA root.

DONATE TO ME
We have to detect which firmware could handle OTA update with root.

Same thing happened on some 257 firmware but...

Sony fixed exploit space that devs used to root and even if you find firmware (like @ktxed) that can be updated on rooted devices - you'll have only partial root.

And that means - you'll be able to flash everything through recovery but as soon as OS boot - you can't write to system anymore.
