Cosmo Communicator - Hardware / New Cosmo Firmware Update
« on: December 11, 2019, 05:12:23 pm »Quote from: TheProfessorNQ
I went ahead with the firmware update. Hit restart or reboot, whatever it said. Now I'm stuck in a boot loop that doesn't get past the splash screen to the boot animation. Then powers off, and immediately restarts. One boot/power off cycle takes about 13-14 seconds. Holding any key/button combinations seems to be of no help. Additional information! I was rooted with magisk. Two failed attempts to install the new firmware, so I flashed the original boot image back to the device and rebooted. That went no problem. Tried the OTA update one more time. This time I didn't get an error message at the end of it. Phone restarted, and here I sit 6 hours later, hoping the battery eventually drains so I can try ADBing in. If anyone has any suggestions, I'd appreciate it. Something I'm noticing as I'm typing this, just as the phone powers down, the screen has a glitch-in-the-matrix style flicker. I doubt that really means anything to anyone, but just in case.
A pre-thanks to everyone!
Most probably you have already tried:
-Press Esc long (takes about 10 secs at the rotating planets)
-Press Esc+silver button (side) long
-Press Esc+Vol Up/Down (next to the cover display) long
Also had a similar (seemed to be related to a magisk module I am trying to develop...) behavior. For me it helped to "reboot" several times using the Esc long press. Booting works when the blue caps lock led turns off. If it stays on the phone is frozen.
If not faint-hearted you might try to remove the back and pull the battery plug. Once I had to resurrect the Gemini (now it's undead this way. It refused to turn on.
