T Beam crashing with Web Flasher update

I am trying to install firmware V2.1.19.eb7025f beta to T-Beam with M8N & SX1262 using web Flasher. I selected device as T Beam and wipe and reinstall device option. Install is successful, but Tbeam display is crashing/no display and TBeam resets frequently. Any pointers to what I am missing would be appreciated. Below is device logs

Tried to install firmware via CLI after erasing the flash. Installation shows successful, but once I set the region the device hangs and reboots arbitrarily.

Response as received from Lilygo

*This has nothing to do with the hardware to check the logs,
The peripheral devices are initialized normally, and the radio, GPS, PMU, and OLED are all normal.

Resetting is caused by software timeout. You can try lowering the mesh firmware version.*

I tried downgrading to version 2.1.14 and still facing same issue.

I happen to run into the same problem on a T-Beam V 1.2 which seems to be supported as it’s only one chip being changed. Still no fun.

Did you manage to solve the problem?
