Hi,
As above, how do i downgrade from 4.3 to 4.22 android? I was on 4.22 Honami rom. I then upgraded to 4.3 honami rom using recovery to flash the new firmware. I have realised that i have lost root access so i want to go back to 4.22 for the time being.
I have read about losing IMEI etc by downgrading so if someone can guide me to the safest method to get back on to 4.22.
This is my first post in a long while so be gentle. If this thread has been opened before than please advise me to it so i can close this one.
Thanks again and look forward to hearing from you lot.
Cheers

I have done it twice, with no issues. Take a nandroid type backup if you are concerned, so you can restore back as it was

not sure if you have reverted yet, but I have root on 4.3
Used SEUS to flash to latest stock FW. (4.3)
Then unlocked bootloader, and flashed CWM using this thread: http://forum.xda-developers.com/show....php?t=2588331
Then flashed the latest SuperSU via CWM, and successfully obtained root.

Since many users are updating their phones(finally) to 4.3 we need to find a way to root it..
For Unlocked Bootloaders you can flash advanced kernel and (wow!) you are rooted!
but what about Locked Bootloaders?

well, since you don't know what a bootloader is, I am pretty sure you have a locked one..with an unlocked bootloader you can flash kernels and custom roms like cyanogenmod

Someone in the "release" thread said that he first unlocked the BL, flashed the advanced kernel, root, then relock the BL.

Why not try that method? It may work anyway as Sony tends to have the same vulnerability across devices with the same firmware

You are correct...... I was only making an assumption but having read doomlords updated thread it will lead to bricked device.
Sure there will be a fix soon for root and recovery on locked bootloader.
Niaboc is releasing his new ROM soon this will have root..... after that just need recovery.

It's almost stock and rooted with unlockable bootloader too
If someone makes stock in update.zip format, you can use full stock rom with root.
1. dont flash the latest 4.3 yet
2. downgrade to 4.2 and root using doomlord method or root by bin4ry method
3. once rooted, backup TA partition
4. flash latest 4.3 via sus, pcc, or ftf
5. unlock bootloader
6. flash custom kernel with recovery
7. boot to recovery, flash supersu update zip
8. reflash original 4.3 kernel
9. restore backup TA
10. enjoy 4.3, root, locked bootloader with intact drm keys!

It would be the same...
However you can also flash Doomlord's 4.3 kernel, then boot to recovery and flash the super su zip for root. The kernel from the leaked 4.3 rom seems to be the same as the kernel from the latest update.
Recovery is lost after going back to stock kernel. Root works.
The root works but Mobile Bravia Engine 2 still lost.

Yes, root works like a charm but you need to unlock bootloader and flash advanced stock kernel from .256 leak cuz it have recovery and flash the file from attachment, then you must revert to stock kernel and lock bootloader. Voila!

I updated my Z1 to 14.2.A.1.136. How do I root it? The methods in the guide stickies I read doesn't work for me. Please assist.
You have to downgrade to android 4.2.2, and then root it, the use [NUT]'s guide to upgrade to 14.2.A.1.136

I don't get it. How do you downgrade it? Will it void the warranty? Also, aren't you suppose to root first, back up the TA partition, then unlock the bootloader?

The .136 cannot be rooted directly but can be Rooted with the method by NUT for Locked Bootloader. On C6903 you can downgrade with Flashtool v0.9.13 directly to .534 with FW provided by NUT to not lose IMEI, then Root with Bin4ry, then Update to .290 with the instructions given HERE, when you have .290 rooted you are ready to update to .136 with the same method HERE.
Watch the Video Tutorial How To in the first Link for .290. It will explain all.
After you get .136 Rooted you can Backup TA First and then Unlock Bootloader. Get Root on your Phone will not void your Warranty, Unlock Bootloader Yes, but if you Backup TA you can Relock your Bootloader without losing Warranty.

1. Did you downgrade with the unofficial Flashtool? Also, did you use the NUTS FTF or the official FTF?
2. Root with Bin4ry? Is that a software?
3. How did you upgrade directly to .136? Via Sony Companion? FOTA? And is root access kept?

Go to NUT tread everything is there but u can skip from 534 to 290 and directly to 136 with full root.That's what I'm doing with full wipe.

Read before post, all threads explain and you asking always the same question. You want root, then there is no official way for it.
BTW, you can use all FTF which you like, I recommended the FTF by NUT because with that you will preserve your IMEI.

To preserve Root you cannot use PC Companion, FOTA or anything like that, just Flashtool v.0.9.13 and update to .136. You can skip the Update to .290 and go directly to .136, both of them using the same method so go for .136.

You can do this also in this way.
Thanks to all who chipped in to help. I currently owned the Z1 for about 4 days. While I previously owned an Android phone, I am totally new to the Sony smartphones as well as their file systems.
Part of the reason why I chose to buy to this phone is the apparent ease of root. However, it seems that that is not the case. 4.3 apparently is not rootable with 1-click. Compounded by the fact is that there is some sort of unique identifier in this TA partition (whatever that is).
Please treat me as a noob and answer my queries with as much info as possible.
Believe me when I said I have done my fair share of reading and trying to understand what is the entire process all about, I am still not really making any sense of most of it. There is only so much Google can do for you before you start seeking personalised advice.
Now, from what I gathered in this thread, I apparently need to:
1. Downgrade to 4.2.2 (.534) firmware, using a FTF posted by someone called Nuts. I need to do this 'cos I don't want to lose my IMEI, which is some sort of bug.
2. I then need to root it with a software called "Root_with_Restore_by_Bin4ry". Apparently, Bin4ry is a person and not a software.
3. Then in order to upgrade to 4.3 (.136), I need to flash a special FTF/ZIP by made by Nuts again, using the unofficial Flashtool.
Am I right so far?
If I flash that special FTF/ZIP, does it deviate my Z1 from stock ROM? Can I still get FOTA updates?
Can I do all this without unlocking the bootloader?
