Can't upload default firmware #220

thx ridwanmullick - resurrection ! :) |
Hello,
I bought a TTGO Call board.
I think it was working ok.
I tried inserting a SIM card, powered on, the light flashed quickly and then slow.
I called the number and it was ringing.
I flash another firmware and I didn't understand at the time I would lost the original one.
Now the board doesn't do anything.
No led neither network initialization.
I tried updating the firmware as described here https://github.com/Xinyuan-LilyGO/LilyGo-T-Call-SIM800/blob/master/doc/How%20to%20update%20firmware.md and it doesn't work.
It never leaves the waiting state.
I tried to press the button, one time, several times, holding on, nothing.
The comms are working, checked with putty and see some cyclical text.
Some text while holding the on board button:
rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPReMQ}1M!} ==T)
flash read err, 1000
ets_main.c 371

So what it seems to me, is that I have lost the default firmware functionality, which enabled celular comms and built in fw update.
So I seem to have broken it.
Isn't there a way of directly burning the default firmware, complete, out of the box to restore the functionality?
Can you pinpoint me to a right direction to solve this?
Thank you very much.
