I have been trying to fix a RUTX11 that stopped working after updating to RUTX_R_00.07.03.4
See this thread
The symptom as of right now are:
1) Cannot enter bootloader recovery mode. I have tried every sort of combination of timing, holding the button, etc but this device just ignores it. The Reset button definitely works because I can hear it click and also pressing it while the unit is booted up does cause it to reset.
2) The device will not connect to the LTE provider - the SIM state is "Inserted" and all data reads (IMEI, ICCID number etc) but the state is constantly "Disconnected". I have tried factory resetting, rolling back firmware, manually setting APNs, copying settings from other known-working units with the same carrier... nothing is working. The carrier is US MOBILE (Verizon MVNO in USA) and all of my other RUT devices are using this same carrier. I have contacted the carrier to be sure that the device/IMEI/ICCID is not blacklisted, out of service etc). I tried flashing all the way back to an old firmware RUTX_R_00.02.06.1 and that seemed to work for a short time, I was able to connect to LTE and data was flowing. But, after some time I tried to update firmware again and then the connection was down.
The unit is from Batch 0025, Hardware revision 0808 if that helps (all of my RUTX11 except 1 are from that batch, and this is the only one giving me major issues right now)
The modem firmware is EG06ALAR04A01M4G (latest I think)
Troubleshoot file is attached.
Please help if you can, thank you
