[Upgrading, Modifying and Unlocking] AndroidLov3r:
Hi! :)

I recently unlocked the bootloader of my Motorola G7 Plus. I did everything right and every time I restart shows a warning about the smartphone being unlocked, and I do have the drivers of the phone updated, the adb & fastboot drivers updated and I have tried 4 different cables and 3 USB ports.

So I want to flash Lineage OS but it is showing me some errors when I try to flash the recovery.img lineage.

*It was starting to download to boot but never ended, and I mean 5 hours (25 mb), only showing (sending.....) and FAILED (remote failure)

*So i tried the methods Lineage recommends fastboot boot__a/boot_a/boot_b/boot__b. RecoveryImageName.img

None of them worked :cautious:

I gave up the idea of trying by Lineage, so I tried with TWRP, didn't install as well. Sometimes just showing (sending....) and stayed there for hours, FAILED (remote failure), but with me trying new commands to fix it started to appear errors about not knowing partitions file sizes, not detecting any partitions and maximum file reached for that partition.

I did try a whole bunch of commands, ways, tutorials but couldn't figure it out.

The phone is perfectly fine, I can´t just flash it :cry:
