SC20 Linux problem

Hi,
I decided to change the SC20 system from android to Linux, but when I flashed a new firmware(SC20ALSAR09 Linux from Quectel FTP), my SC20 did not work, and I have no access to the Linux console by UART.

My UART logs:

Hi Ricardo_Aguiar,
From the log, your device entered fastboot mode, so you have no access to the Linux console by Uart.
Which module are you using? Could you tell me the IMEI?

And what’s your Android version?

Hi @Jonas-Q

IMEI:864430010001091
Android 7.1

If you burn the Android images again, can it start up nomally?

@Jonas-Q
I’ve flashed the firmware several times and it doesn’t work. Android works perfectly but Linux firmware is in this fastboot state.

@Jonas-Q
yes, android works perfectly.

After burn the Android firmware, please send AT command AT+EGMR=0,7 via qcom and share me the output.
By the way, could you tell me which country and which company you are?

@Jonas-Q
How can I send AT command? I tried via QCOM but it didn’t work.
Company: Agres;
Country: Brazil.

You device missed QCN, but I don’t make sure whether is it related to the uart issue. Could you tell me your email? I will send you a QCN file to restore QCN first.

Could you take a picture of your using module so that I can get the right IMEI number of your module?

My sc20 doesn’t have a shield.

Could you ask the third-part hardware for this info? I can not provide you QCN file if I don’t know the IMEI.
