EML-L29 P20 Stuck on Logo


Dear team I have a P20 EML-L29.
It was working fine and I tried to downgrade it via board firmware.

It failed to write board firmware and then phone stuck on First logo.

I tried to update bootloader and oem info, it said successfully updated and phones goes to fastboot mode with blank screen.

But always failed to write any firmware.

I tried to write many firmwares but failed.

Also it failed to go to upgrade mode.

It always shows same info even I write different bootloader and oem info.

Now I want to make it alive again.

Please DC Phoenix team help me step by step in a proper way.

Also I want to know if I can convert it to EML-L09..
Also I couldn't find oem info for EML-L09.
