Hello,

 

Today i will show you how to unbrick your Sony Xperia Z Ultra C6802 / C6806 / C6833 and update boot. Sony Xperia Z Ultra smartphone can be bricked during firmware flash to version 14_2_A_0_290 or newer using obsolete Flashtool (Version older than 0.9.13) or other third party tools. 

 

If after flash your phone is dead and you have warranty - send your phone to Sony - you will get new phone.

 

If after flash your phone is dead and you do not have warranty, this tutorial is for you. Remember, during this process you can damage your phone, everything you are doing on your own risk. For 99% your phone will not be 100% functional, for example it will not be waterproof anymore if you will disassemble or reassemble it improperly.

 

 

Bricked phone symptoms:

 

  • can't power on after flash,
  • no lcd or led reaction for power button,
  • no lcd or led reaction for charger,
  • no lcd or led reaction if phone is connected to PC,
  • your PC can't detect your phone with vol-,
  • phone does not vibrate when holding vol+ and power together.

Your phone is bricked after flash, because your flasher did not updated boot in your Xperia Z Ultra smartphone during flash, what is required when flashing 14_2_A_0_290 firmware or newer. Let's fix that.

 

1. First step is very difficult, you must disassemble your phone, remove back cover and get access to the main board. Please download Sony Xperia Z Ultra service manual from our forum: http://sony.yt/topic...kcja-serwisowa/ and read working instructions carefully.

 

Also that disassembly video may be helpful:

 

 

2. Download and install the latest Gordon's Gate Flash Driver from this post: Attached File  ggsetup-3.0.0.7.exe   3.58MB   12856 downloads

 

3. Remove battery from your phone and localize testpoint on your main board (it's marked with red circle): 

 

Attached File  C68xx.jpg   148.83K   166 downloads

 

Using paperclip or testpoint wire connect this point to GND (for example metal shield or sim card holder) and attach USB cable. Your computer should detect SEMC Flash Device in device manager. If yes, disconnect your phone.

 

Hint: Now you can enable emergency mode in your phone, so next steps will be easier to do. To do that remove battery, connect testpoint to GND, insert battery, press power on button, disconnect testpoint. Now your phone is in emergency mode.

 

4. Download and run this s1tool: Attached File  s1tool.exe   2.03MB   1531 downloads

 

5. Download proper APPSW firmware for your Sony Xperia Z Ultra:

 

For C6802: Attached File  C6802.rar   19.36MB   612 downloads

 

For C6806: Attached File  C6806.rar   19.36MB   301 downloads

 

For C6833: Attached File  C6833.rar   19.36MB   1649 downloads

 

6. In S1tool choose MSM8974 emergency mode, press Flash button, select correct APPSW .sin_file_set file (or you can select whole firmware if you have it in order APPSW, FSP, Elabel - but you can't use .ftf flashtool files),

 

7. Press Testpoint READY button:

 

Attached File  1.jpg   89.35K   106 downloads

 

and if your phone is in emergency mode, just attach usb cable. If not, perform all steps from point 3 (connect testpoint to GND and attach USB cable).

 

8. When drivers will be installed and phone will be detected, program will ask you to disconnect testpoint. If your phone is in emergency mode, just press Testpoint READY button. If no, disconnect testpoint from GND and press Testpoint READY button.

 

9. After that phone will load emergency s1 loader, re-enumerate usb, load s1 loader, update boot in your phone and flash selected firmware. When it's done and you have flashed all firmware parts (APPSW, FSP, ELABEL), phone will be fixed. If not, you must reflash it fully with Sony Update Service, Sony PC Companion or any other flasher like current Flashtool version or this S1tool.

 

10. Time to reassembly your phone using service manual: http://sony.yt/topic...kcja-serwisowa/

 

Also reassembly movie may be helpful:

 

 

 

Now your phone should be alive :) But if you will see message: 

HARDWARE ID : XXXXXXXXXXXXXXXX not supported

Bad luck, your phone can't be fixed. My suggestion: search for working Xperia Z Ultra with broken lcd and swap main board.

Best regards,

 

Jurij

Sorry, your hash is not supported, you can't fix this main board using S1tool emergency mode.

No, that is not hardbricked phone. It's just not flashed properly. In that case you should repeat flash procedure. If PC Companion does not want to update your phone, try for example Flashtool  :)

If phone is turning on, there is no problem with damaged boot / boot update issue. How did you damaged your phone?

Try to flash your phone in s1 emergency mode or flash mode. If that will not help, it's hardware problem.

Thanks

i am also getting the same result.

 

what have i done wrong?

 

it seems like it is not doing anything?

 

i am able to see SOMC in device manager. So that mean my problem is that my mainboard is ok and only flash is not done correctly? so had to use flashtool to reflash? but I could not power up the tablet and so how do I flash another firmware?

 

Please help. thanks!

Your hash is not supported, nothing to do with s1tool.

So boot is not damaged. Flash your phone with flashtool / pc companion / other service tool.

This is the only driver you need: Attached File  ggsetup-3.0.0.7.exe   3.58MB   12856 downloads If you can't flash it with pc companion / flashtool, buy working Z ultra with broken lcd and swap main board.

i am not sure if the mainboard is the issue. reason why is because if i connect the Ultra Z to my computer, it will detect and try to install driver and the LEd will show red light. but during the driver installation, it will pop error saying it could not find the driver, etc.

But firmware from Z Ultra? If yes, you should be able to flash correct firmware again.

Yes, it is the latest firmware 5.1.1. But I didn't delete a file during the firmware building.

But now I press power with vol up or vol down and there is nothing.
