Hi everyone,
Quectel_EG91EFB_boot_fail_log.txt (46.2 KB)
I’m currently doing some tests with a Quectel EG91EFB module
The module is currently unable to fully boot. It attempts to start, fails, and restarts in a loop. I’m attaching the log file showing the initialization errors (like flash initialization issues) in case it helps pinpoint the problem. Any guidance on how to proceed with flashing under these conditions would be much appreciated!
Could someone please send me:
Thank you very much in advance!

Update: I was able to enter fastboot mode over USB.
fastboot devices returns:
ee74cf99 fastboot
fastboot getvar all shows:
version: 0.5
kernel: lk
product: MDM9607
serialno: ee74cf99
version-baseband: blank
version-bootloader: blank
fastboot oem device-info shows:
Device tampered: false
Device unlocked: false
I also checked the partitions mentioned in the boot log:
fastboot getvar partition-size:devinfo
partition-size:devinfo:
fastboot getvar partition-size:config
partition-size:config:
fastboot getvar partition-size:frp
partition-size:frp:
These return blank, which seems to match the debug log errors:
ERROR: No devinfo partition found
Neither ‘config’ nor ‘frp’ partition found
Does this indicate that the partition table or firmware image is corrupted/incomplete? If so, could Quectel provide the correct signed full recovery firmware / firehose package and flashing procedure for EG91-EFB-512-SNND?
Can someone reply soon? I’m on a deadline and am stuck until this issue is fixed.
