No WiFi after update - cannot enable (not responding)


  • My unit 4G/Wifi option with reverse cam before stuck on black screen of death on boot was in the past:

    QCM6125 12 S10A_123 eng.hct.20230406.105233 EAU

    MCU: HCTGQ_HCT_V4.03_1

    Apr 4 2023 13:34:20

    I managed to enter to recovery mode and becouse lack of original software backup I put there:

    gmcu.img V4.12 first and update zst27_sc138_12_(20240513).zip ( I wiped flash of course).

    MCU: HCTGQ_HCT_V4.12_1

    Mar 13 2024 09:44:14

    QCM6125 12 S10A_123 eng.hct3.20240513.152630W

    The unit revived but now I don't have WiFi - the option is available in menu, but after I put it to on app suspends a little and nothing happens. Tried also gmcu.img V4.13 and gmcu.img V4.54

     

    The second observation - no other update than zst27_sc138_12_(20240513).zip boots correctly. Other G12's updates stop on the launcher's start and reset the unit. I always have to return to zst27_sc138_12_(20240513).zip to boot radio to normal operation, but there is no possible to execute command WiFi to on.(GUI can do it but hardware is not).

    The BT chip is FSC-BT825B V1.1 and in the factory settings works under FSC_BW124 setting option. Tries other BT options, but it didn't help for WiFi.

    IF I understand well the Wifi is in Fibocom unit becouse there is only antenna output. How to revive the wifi to have internet connectivity? Which firmware or MCU should be updated?

  • @Support Dasaita I have MCU on  gmcu.img - is it safe to update from hmcu.img?  How to do it, because system update searches for gmcu.img?
