OLED stopped working after upgrading to firmware-tlora-v1-1.2.59.d81c1c0.bin

Hi,

One of my LILYGO® TTGO T-Beam was running 1.2.53.19c1f9f
and used with “–set is_router true” and worked fine for weeks.

Today I decided to solder the OLED and after switching the t-beam on it worked fine.
Then I upgraded the Firmware to firmware-tlora-v1-1.2.59.d81c1c0.bin and now the OLED
is not displaying anything. Like it is not powered at all.

A red led blinks once if i connect the usb port but the blue led is not flashing once a second
as usual.

First I throught I bricked the t-beam with the firmware-tlora-v1-1.2.59.d81c1c0.bin but then
i noticed that it still responds to “meshtastic --port /dev/ttyACM0 --info” etc.

I assumed that this could be related to “–set is_router true” so I set it to “–set is_router false”
but still no light in the OLED.

I downgraded to firmware-1.2.58.6af1822 and later even to firmware-1.2.52.b63802c
but still no OLED and no blue LED flashing.

I am wondering if this is a hardware problem, or some software setting causing this ?
Should I factory reset the device ?
Is there anything i cloud measure ?

Thanks in advance.

You need to flash the tbeam firmware, the tlora is a different board

Oh, yes, you are totally right!
Stupid me.
I am sorry for that.

I now flashed firmware-tbeam-1.2.59.d81c1c0.bin and all works fine!
I am very happy that it is not a hardware fault.
