[Moto G7 Power Questions & Answers] KUSANAGUI:
Hello I have the version XT1955-2 (1SIM)(RETAIL)(TEFPE), I RECEIVED THE LAST UPDATE OF ANDROID 10 QPOS30.52-29-2

BEFORE ANDROID 9 THIS WAS NOT HAPPENING:

Having the cell phone on, I have changed the sim and it no longer recognizes it, or the micro sd memory, I had to

do a reboot, so that they just recognize the sim AND the SD memory.

The memory is ok and the 2 sim cards, because I have tested them on another phone with android 10.

-If I insert the SD memory only if it recognizes it.

-If I insert the SD and the SIM, it does not recognize either.

-If I insert only the SIM, it does not recognize it.

I have tried doing a factory format, with the recovery, wipe data / cache and reboot system now and nothing.

DOES THE MOTOROLA ROM HAVE ANY BUG?

EDITION:

because the operator movistar Peru (software channel TEFPE), still does not send android Q (10), it only had

this rom version:

OCEAN_PPOS29.114_134_13_cid50_subsidy_DEFAULT_regulatory_DEFAULT_CFC.xml

THEN I FLASHED HIM VIA FASTBOOT AND PC.

I USED THE ROMS

QPOS30.52-29-2 (JUNE 1, 2020)

RETAIL

TEFMX

RETLA

3 TIMES I INSTALLED THE ROM OF ANDROID 10, BECAUSE IT APPEARS THAT THE CELL PHONE DID NOT START CORRECTLY and THEN I REALIZED THAT THE COMMAND WAS MISSING:

./fastboot flash system_a system.img_sparsechunk.10

THEN I REPEATED THE INSTALLATION PROCESS AND THE ROM WORKED.

THIS IS THE ROM:

OCEAN_RETAIL_10_QPOS30.52-29-2_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml

But I noticed the SIM card problem, and I thought it was the rom problem and then I flash the 3 roms again, and the

The problem remained, so after installing the latest rom, I did a factory reset, from the recovery:

wipe / data and cache, reboot now. And the problem continued.

I then tried to flash android 9 stock, to find out if it was a ROM problem, with Rescue and Smart Assistant and it no longer detects

compatible software in fastboot mode.

Then as I had the stock rom (pie) that I had already downloaded before with Rescue and Smart Assistant, if something bad happened

like what I'm going through, I flash it but it doesn't boot the system, a bootloop happens.

the motorola image appears and then disappears and reappears again, but in the power sheel window this is the only thing

error that appears:
