Hi,

I wanted to flash Android 11 on SA8195P, hence i built android code and chip code as per documentation (source :https://docviewer.qualcomm.com/releasenote/RNO-211002234111). Used vendor prebuits of https://createpoint.qti.qualcomm.com/planner/link/search/newReleaseHisto... in android code as per documentation.
On the first try, i flashed only HLOS images. Then in logged into fastboot userspace and flashed system.img. Basically due to some error now device is not booting normally or in fastboot mode.
 
After above issue, I tried below methods to flash :
 
1. I tried by forcing fastboot (S7 long press) and flashing it. You can find logs here : https://pastebin.com/raw/pYPpQGJ7
Note : It required BTFM.bin file which is not provided in the code by qualcomm hlos dev chipcode for 8195. I just used 8155 file
 
2. I also tried with QFIL using linux qdl tool. You can find logs here : https://controlc.com/c933fdd7 . I switch S3 pin 7 to turn on EDL mode and flash it.
 
Both the cases it is getting flashed successfully. But once i reboot, device is not getting detected i.e doesn't boot in fastboot mode or normal mode.
 
Please help me out to resolve this issue

Hi 

Could you try to flash boot.img vendor_boot.img vbmeta.img vbmeta_system.img super.img in bootloader?

If it boot up failed, please collect boot up uart log.
