What is at! gstatus? And at! selrat?
Can you post your logcag radio log?

mgorski117 · February 20, 2019, 12:01am

I just did a rmareset because when I listed bands with at!band? the lte bands were disabled. I am re-converting to 9071 again and flashing Verizon and also AT&T.

Does the Android RIL not work when the carrier is not set to Verizon?

Is it possible to set just the carrier to Verizon and enable all gsm LTE bands?

Thanks a million for all your help…

mgorski117 · February 20, 2019, 12:40am

Now I am back to the Firmware error again after flashing current Verizon:

Firmware application version: SWI9X30C_02.30.01.01
E/use-Rlog/RLOG-RIL( 482): getFirmwareInfoTechQMI: Info invalid after initFirmwareInfoQMI()

mgorski117 · February 20, 2019, 12:41am

How do i set this specifically?

mgorski117 · February 20, 2019, 12:51am

Where can I find archived firmware? Now the RIL is expecting a previous firmware version since I am using 32bit arm on android 5.1 (I assume).

mgorski117 · February 20, 2019, 1:08am

Im confused from the AT reference manual how i set the “carrier-string”

Usage:
• Execution: AT!IMPREF=
Response: OK

mgorski117 · February 20, 2019, 1:34am

So this config works but current Verizon does not in 5.1 Android RIL…

Okay well now im stuck at the Firmware error so if possible could you PM me with a proper ATT firmware archive that will work? My current log is repeating the firmware error again now and RIL will not fire up

mgorski117 · February 20, 2019, 3:18am

Yes thats exactly what I am using but when the Verizon FW version changed the RIL got the Firmware error:

Ive flashed ATT, and VZW

002.052_001 02.30.01.01_VERIZON does not work

002.012_002 02.08.02.00_VERIZON Worked

Any archives for PRI FF GOOD 0 0 0 002.012_002 02.08.02.00_VERIZON?

mgorski117 · February 20, 2019, 2:11pm

Sure i’ll grab a log and paste it here in a bit . Do you know if Sierra provides past archived firmware. From my searches its hard to find a specific firmware version…

jyijyi · February 20, 2019, 2:44pm

I cannot find in source.sierrawireless.com …
Btw, please also provide the good log for comparison.

mgorski117 · February 20, 2019, 3:38pm

Thanks for the reply and thanks for looking. I am not sure I can get back to a good log with the newer Verizon firmware flashed:

I will be able to paste a full log for 002.052_001 02.30.01.01_VERIZON but I can’t get back to 002.012_002 02.08.02.00_VERIZON with out a previous firmware package. It would be great if there was an archive on github…

Okay well i found the firmware version I am looking for here : https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=mgmmf

So I am going to at!RMARESET=1 again flash 02.08.02.00 then flash back to Generic em7455 9071

See what happens with the old firmware again…

mgorski117 · February 20, 2019, 7:06pm

Okay I have great news @jyijyi

When using an older Android RIL (5.1.1) the QMI RIL looks for the firmware version of the same date range ie 2015-2016 so when I flashed the OEM Dell Generic 02.08.02.00 then converted to 9071 via AT! and did NOT flash updated 2018 firmware. Now I am getting full bars and LTE speeds with GENERIC provider string and FW version 02.08.02.00. Thank you soooo much for guiding me through this, very much appreciated:

mgorski117 · February 20, 2019, 7:25pm

I want also add that I can only get LTE on Google Fi, T-Mobile is still stuck on UMTS so I will have to adjust enabled bands since I am probably using Sprint settings (Google Fi uses Sprint, US Cellular and T-Mobile)

I need to try and dig up this Firmware version for ATT?
