As you may know, you have to back up the TA-partition before you put a custom ROM on the Sony Xperia Z1. I've backed up the partition with this .bat file: http://forum.xda-developers.com/showthread.php?t=2292598&highlight=ta

I've rooted my Z1 successfully and flashed a custom ROM on it (PACMAN-ROM). Right after that, I've tried to restore the TA-partition with that same program (.bat file), because the camera didn't work well (the camera wouldn't focus and the flash wasn't working).

Everything went well until the program asked me to reboot the device. It shut down and did not boot again.

I've tried to put a boot image (adv-stock-v3.img) on it again with CMD (SDK, platform-tools, ya know) while the Z1 is in fastboot-modus.

But I keep getting the "FAILED <remote: Command not allowed>"-error.

C:\Users\Teake\Desktop\adt-bundle-windows-x86-20130917\sdk\platform-tools> fastboot flash boot adv-stock-v3.img
sending 'boot' (13254 KB)...
OKAY [  0.454s]
writing 'boot'...
FAILED <remote: Command not allowed>
finished. total time: 0.458s

How can I get my boot image working again on my Z1?

Try to re-install ROM on your device (here's the newest firmware), that usually helps in similar situations.

If your phone will be still broken that means you have damaged bootloader (boot partition) - then try to re-install boot partition (you can find instructions in internet).

At most you can give your phone to service and tell that your phone has been broken during an update. Repair will be free if you have warranty.

  • how do I do that? You mean fastboot? I've tried that already. I keep getting that error.with my previous galaxy s2 everything was a lot easier so I don't know these things with cmd really well.. Oct 26, 2013 at 18:14
  • It's called FLashMode on Xperia devices. Install PC Companion and follow the instructions, it should automatically guide you through the process of booting into FlashMode/Fastboot mode (i.e. tells you the necessary button combo during start) and then should load the latest software onto it. You can also use Androxyde's Flashtool to install a custom ROM or a pre-downloaded factory image.
