I have a problem after upgrading firmware from ancient 00.03.05 to higher version. Modem upgraded successfully to 01.14.02 but stuck on boot and hold (1199:9090).
Bus 001 Device 010: ID 1199:9090 Sierra Wireless, Inc. EM7565
I’m unable to revert to old firmware because i don’t have it. So i grabbed a log from dram. It says that it’s unable to find FOTA partition and some nv items are incorrect. Most interesting things are:
B - 425078 - hw_family:2, hw_type:2, hw_rev:16
B - 450119 - idsflashinit, could not get FOTA partition name
B - 460672 - Failed to read size: /swinv/item_files/CUST_IM_SWITCH_HIDE
B - 465826 - Failed to read size: /swinv/item_files/CUST_NETWORKNAMEFMT
B - 467931 - Failed to read size: /swinv/item_files/MBIM_CUSTOM_DATACLASS
B - 480466 - Failed to read size: /swinv/item_files/LOCK_ROOT_ON_BOOT
I see several ways to fix it.
- Revert to old firmware or oldest release, like 01.00.02. How could i get old firmware?
- Download whole flash. I have appropriate bin file but i have no idea, how to manage that. I made several downloaders for qualcomm based devices long time ago (msm5xxx, 6xxx) and i know that i need tsr loader for that. I don’t have such for this chipset. The question is how to write whole flash image or where to get tsr loader/programmer?
- Repartition the device. How could i make it?
p.s. i’ve tried 01.05.01, 01.07.02, 01.08.04, 01.09.04, 01.11.00, 01.14.02, 01.14.05 with same result.
Thanks a lot for help
