Default [GUIDE] How to root 14.1.B.2.257 using OTA

Finaly after a lot of trail and error I succeeded to keep root.

All the info in my post is scattered trough this forum, I'm only putting it in one place. All the credits and thanks to the guys who made this possible.

ONLY ON STOCK NO MODIFIED KERNEL OR RECOVERY

Use flashtool to flash 14.1.B.1.532,

Code:

Flashtool download and guide by krabappel 2548:

Use vroot to root the 14.1.B.1.532 firmware

Code:

Set supersu to survive OTA

Code:
Install Voodoo OTA RootKeeper: 
https://play.google.com/store/apps/d....otarootkeeper
Backup "su" with Voodoo OTA RootKeeper

Update the build.prop with German CDA Code

German CDA code: C6833_1275-8026

ALSO CHANGE "ro.somc.customerid" SET IT TO 436

ALSO CHANGE "ro.semc.version.cust_revision=" SET IT TO R11A

Reboot your device

Check voodoo if backup is still present

If present, go to software update to install OTA.

When followed this step by step you're on the new firmware with root.

And as usual, everything at your own risk.

Thanks. It's nice with a complete rooting tutorial with links in one place One question though; do we lose everything when we're downgrading to .532?

Yes,

My documents and photos are on a sdcard, with some back up of apps. When google acount is created all apps are downloaded automatically, so i don't bother loosing...

Off course you can use in this case your own CDA.

(I tried to write it in such a way that somebody with minor knowledge is able to do this faultless.)

Well, it's clearly not necessary to change your CDA if you've already received the OTA.

Alright, all i have left is to update to 257 again, but i only have 33% battery left and it's not possible to do it unless i have at least 50%. Just typical Everything else went smooth, and i didn't have any issues

Edit: I'm done updating, and i got root

Edit 2: Hah! I tried using Sony's own backup app before downgrading and everything, feeling that the backup wouldn't be there after the full wipe, but it is indeed there and i have some game saves and stuff there! Awesome!

Germany is using C6833. Is it compatible with C6802?
Noob question: can I flash the C6833 FTF ver 532 on my C6802? I can not find the FTF for 532 Vietnam version, the 510 VN got bootloop and the Generic TW have many Chinese software that I don't like

I don't know, I've C6833. Be adventurous When it's not working correctly you can always flash back. In the generic TW version you can always delete the chinese software, one of the pros of root
