Hi Team,

I know that "fastboot bbk unlock_vivo" will unlock vivo boot loader if it has PD1510F_EX_C version which was worked for me.

But I downgraded to PD1510F_EX_A version. During the process I used wrong "rawprogram_unsparse.xml " file and hence I am facing these below issues.

1.Wifi is not working
2.IMEI is not shown
3.by Pressing Vol + and Vol - in QFIL tool the port is not detected and enters into Fastboot mode. Hence I cannot flash any more stock rom using QFIL.
4.Bootloader is locked and hence I cannot use flash_all.bat file (which can be seen inside inside falsh zip) as it is giving unknown command or device is locked.
5.Dailing *#558# can open the debug port and port is getting detected in PC device manager and QFIL. But Power off phone and Pressing Vol + and Vol - and connect USB to PC is not detecting port in QFIL tool which is required to falsh the stock rom
6.Tried IMEI and SN Write tools but It failed.

Totally I got stuck up with No way. Please show some lights to get out from here.

Your help is appreciated.

Thanks,
Ramesh
