@ blinet,

What an issue current phone has?
What firmware you are trying to flash into the phone?
What firmware version it originally had?

Best Regards
GSMServer team

We added option of manually Kirin bootloader selection before factory firmware flashing.

You may manually select another Kirin bootloader for factory firmware flashing from the Autodetect drop-down menu.

Hello team..
I have a question in my mind..
Can we write board firmware on P20 EML-L29.. I downloaded many firmware from easy firmware site but all failed.

I want to make sure about Sigma..

My phone was working I just tried to downgrade it...

Then it failed and now not writing board software..

How can I write board software.. Or otherwise how can I make my phone alive and working again...
I tried everything but phone not going to upgrade mode..
