Sony.yt - International Sony Forum

Hello,

 

Today i will show you how to unbrick your Sony Xperia Z1 C6903 and update boot. Sony Xperia Z1 C6902 is currently not supported. Sony Xperia Z1 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 Z1 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 Z1 service manual from our forum: http://sony.yt/topic...kcja-serwisowa/ and read working instructions carefully.

 

 

2. Download and install the latest Gordon's Gate Flash Driver from this post:  ggsetup-3.0.0.7.exe   3.58MB   14086 downloads

 

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

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:  s1tool 6II2015.exe   3.12MB   3496 downloads

 

5. Download proper APPSW firmware for your Sony Xperia Z1:

 

For C6903:  C6903.rar   19.34MB   2438 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:

 

 

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/

 

 

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 Z1 with broken lcd and swap main board.

it stop at waiting for phone... nothing happen

 

tested with xp 32 and 64 and seven 64

instaled all driver

trayed with two different original sony usb cable 

trayed with usb 1 usb 2.0 usb 3.0

 

thank you for any help

Does any device shows up in device manager when you connect testpoint and usb cable? Try the latest s1tool version:  s1tool 6II2015.exe   3.12MB   3496 downloads If your phone is C6902, it's not supported.

hi

it show semc flash drive

and tested with s1tool 6II2015.exe  it's the same problem

but im not sure it's a c6903 or c6902 i have a working c6903 it's green pcb and the one that im traying to repair is blue pcb but have exactly all the composant of the c6903

so how can i identify if its a c6903 or c6902 ( i have only the pcb)

So analyse imei number. For example TAC 35809405 belongs to C6902. But it's strange, it looks like program is waiting for a phone. Maybe in second step try to connect battery after making testpoint and before pressing ready button...

trayed , but same problem 

when i push ready button i get the sound of removing usb nothing more it's look like that it can't reboot by it self

i supose this is very hard brick

Maybe disconnect and connect again usb cable then?

when i do this i have a loading barre but still waiting for phone....

This is the oldest s1tool you can try:  s1tool.exe   2.03MB   1678 downloads . If that will not help, i can't advice you nothing more than to buy working xperia z1 with broken lcd and swap main board...

tested too but same result

thank you any way

Are you sure that during repair procedure all programs from Sony and other flashers are disabled? Also in tray (near system clock) please make sure that all PC Companion and other programs are closed.

yep trayed with fresh windows xp sp3 32 bit fresh instalation with only driver instaled on it

same problem

 

the problem is the phone can't reboot by it self after click ready

I would try to change testpoint wire and search for a different testpoint If you have time and nothing to loose... it's worth to try

Ok there is six point one of them is gnd so ok i will test the other ones

As a gnd you can use metal shield.

There is like 15 point test

Tested all point and get different error like
DLOAD PROTOCOL AND get error after this
or usb#?... error
i will copy the logs later

Now i have to retest with atached battery
do i have to use emergency mode only or i can use flash mode?

It's written in first post how to find testpoint. Connect each golden point to gnd (metal shield for example) and attach usb cable. When you will see new device in device manager - that's it. Then you can use emergency mode to flash your phone. You can test all golden points one by one.
