Hello. How can I fix the modem broken RM502Q-GL? It is visible in the system as 9008. When trying to firmware, it is disabled because it restarts every 15 seconds. Help me, please.
Dear @Stanislav_Potapov
What did you do before? It can’t power on successfully, right?
During the upgrade, did you poweroff or others?
Please try to upgrade again. After module power on, then pull down the powerkey and try to upgrade.
The module hung up during the update process and hung for many hours, I had to turn it off and turn it on again. I tried to turn off and turn on the power many times, the module always loads in 9008 mode. I tried to run the update many times, it didn’t work.
Dear @Stanislav_Potapov
During the update process, it can’t power down the device.
It is hard to say whether the hardware was broken.
The module works because it consumes current, but cannot be updated because it is always loaded in edl 9008 mode.
Please. How to do it?
