Sony Xperia XA1 Ultra Boot Repair G3221 with UFI (DONE)

Sony Xperia XA1 Ultra Bricked!

Case: 

 XA1 Ultra is flashed with wrong firmware (another type of XA1 ultra <he said G3223>, but not G3221) and can not be flashed by Setool anymore! Setool find the phone for the first time (over MTK Port) by pressing vol dn and connecting usb cable and result an error like below:

PLEASE ATTACH TURNED OFF PHONE NOW

PRESS AND HOLD "BACK" OR "VOLUME DOWN" BUTTON ...

S1BOOT NOT DETECTED

FAILED TO SETUP PHONE

Elapsed: 5 seconds

Solution:

XA1 ultra has 32gb emmc (HBG4a2, SK Hynix) BGA 221 package, not epoxied, there is no glue under the chip, so easy to remove from board. Emmc boot config should be enabled for Boot Partition 1. 

I removed the chip, reballed and connected it to UFIBOX, there was no any abnormal situation with the chip, boot config was correct, partitions are ok.

I have another alive XA1 Ultra G3221, I removed the emmc chip and read boot1, boot2 partitions and  and exdcsd.bin. Just wrote these files to bricked one and installed both of them back.

so, it was flashable by Setool then:(also you can flash any other tool)

If your brick story like mine you can use my solution with this caution:

All risk is yours, just because this solution works for me does not guarantee that it will work for you!

Thanks.
