Hey all, after a couple of tutotials I came to a conclusion that trying to remove the unlocked bootloader screen bricks my phone everytime with the flash failure error...
Right now i'm unable to use my phone, since it is bricked, and i'm trying to flash it to work.
Any ideas why I can't change the boot screen? It keeps giving me this none signed image error
EDIT: Can't seem to make it work at all now. Is there a way to erase everything from the phone and flash a new ics?
I could be wrong, but I thought I read someone saying that this was possible with ICS, but with JB this has been locked/disabled from modification.

Download an JB Fastboot and flash the ulogo back > problem solved.

Edit: If you're still on ICS forget the part about the JB Fastboot and grap this one.

I'm kinda worn out by the slow release of updates and would like to go CM.
Having locked bootloader, I am unclear from reading/searching if I can, say in a few months, go back to stock (flash using FlashTool?) so I can sell the phone before I upgrade?
Thanks for any tips or RTFM links. :good:
You can't flash CM with a locked bootloader. CM needs a modified kernel to work and with a LB you can't do that. But to answer your question, yes you can. Simply wipe everything before flashing with flashtool and you are good to go.

So, in my case I need to
1. Unlock Bootloader (which will erase everything, including SD card)
2. Flash CM
3. Enjoy until time comes to sell device
4. Wipe data/cache/factory reset
5. FlashTool the latest STOCK I find
Is it accurate to assume that after step 5, the only difference between my (current) stock device and then will be unlocked bootloader (with zero impact for guy who buys after me) ? As much as I want to have KitKat, I do not want the buyer to be funked with something not matching his/her needs or impaired somehow...
Thank you for the confirmation :good:

After step 5 you can relock your BL by reflashing your TA partition (which you should backup before step 1) if i'm not mistaken.
Step 1) backup TA partition.
Step 2) unlock bootloader.
Step 3) flash cm.
Use as you wish.
When you want to sell device.
Step 1) Restore TA partition.
TA restore will block to boot with modified boot image.
Step 3) flash stock fw via flashtool. Do not select or unselect anything in flashtool.
That will flash full device including sdcard.

What is the risk of not reflashing the TA partition and flashing STOCK onto unlocked BL? Not receiving OTA updates or something more complex?

You lose your DRM keys. People say bravia engine stops working on photos and some stuff with the music info downloading with walkman. Unsure about OTA updates, as i have never done those. I flash FTF as soon as they get available.
Other than that, there is nothing different.

The SD card shouldn't get wiped when unlocking but the internal storage does.

Thank you to all who pitched in - I searched the fora for "TA partition" and discovered that [NUT has written a wonderful thread for people who have my question, I wish I knew about the TA partition importance and searched earlier.
For those who follow or need the same thing, thread is here: http://forum.xda-developers.com/showthread.php?t=2458530

hi you all, i have an xperia z rooted with doomlord toolkit v18, and an dual recovery 2.7.14 installed. i have successfully flashed and backed up the eXsitenZ 5.0.0 rom (by niaboc79 Great success by the way). so now iwant to install the famous doomkernel and i have a few question because the information i got from around the net is confusing.
so here are my questions:
1. Is installing the eXsitenZ means i have unlocked my BOOTLOADER?
2. do i have to unlock my bootloader in order to install DOOMKERNEL?
3. is unlocking the bootloader is irreversible?
thanks ahead for any kind of help, greetings perfect9stranger.

1. No, you only have to unlock your bootloader for a custom kernel. There is also written that the existenz is for LB(locked bootloader) and UB(unlocked bootloader).
2. Yes.
3. Before you unlock bootloader, it would be good to make a TA backup. There are DRM-keys included. If you loose them, you loose warranty.
Because once you have unlocked your bootloader, without a backup of the TA, you will never get the DRM-keys back.
So only relocking the bootloader is not always enough.
The TA includes unique data and that is the reason why you can't restore the backup of an other phone. If you do it you will hardbrick your phone.

Hello everyone, I unlocked my bootloader for root purposes and backed up my TA image.
Restoring TA cures the camera problems, but my attest keys are lost... (what are they for?)
Anyway is there a way now to get back to stock and relock the bootloader?
