[Moto G6 Questions & Answers] mateusrm:
Hi, This is my first post on XDA and I'm seeking help to solve a problem with my device.

I Have a brazillian moto g6 (with dual SIM support) that was having the random glitch and lags problem that some G6's had after the OTA update to Pie. A friend of mine bought the same device and was having the same issue after the OTA update, the phone was barely usable. After reading online, I decided to do a clean flash of the stock brazillian ROM because I saw people talking that this would solve the problem. I Have some experience in flashing ROMs, unlocking bootloaders, installing recoveries, kernels, etc (In my pixel phone, and before in a moto g5 plus), so I imagine it would be pretty easy.

I Started trying to flash via RSD Lite but for some reason the program didn't recognize the device. I even intalled Windows 7 to see if it was any compatibility issue. RSD could recognize with no problem my old moto G1, but the G6 not. I was using motorola's original USB cable.

So I resolved to flash via fastboot, using a bunch of commands I saw in a XDA post saying that the commands were essentially the same from the Oreo stock flash post. Before that, I unlocked the bootloader in Motorola's official site to be able to install TWRP in case anything gone wrong.

After flashing the stock rom, everything was fine and the lags stopped, but the phone didn't recognize the SIM Card. So I decided to reflash the stock ROM using a python script to convert the XML to fastboot commands, in case any command was missing. The same problem insisted, the phone does not see the SIM card. I tried a bunch of things like flashing oreo modem, US ROM, etc, but there's no way that the phone recognize the SIM card.

In fastboot the phone exibits "Baseband: not found" so I Believe that somehow in the process I bricked the phone. Anyone has a clue on how to solve that? Is it possible to reconstruct the baseband without a Box?

Anyone know why RSD didn't recognize the phone? Could it be a failure in the first flashing proccess? (All comands were essentially the same, except that some .sparcechunks were missing, but the modem stuff was equal).

Since now, I apologize for some bad english and I would really appreciateif someone could give me help.

Thanks in advance.
