Serious problem in the Moto G5 Cedric xt 1672! (Help me please!!)

[sonmota]

friends, how are you?
It's the following .. I have a serious problem with my Moto G5.

When he went to do the update for Oreo he gave a problem ... Of which I can not leave.

It starts in fastboot mode or attempts to initialize Android but stops on screen (M) as picture.

The bootloader is locked, I tried to unlock by cmd and put the key sent by the motorola, signaled as if it worked and continues as (oem_locked).
I do not have root, my bootloader is locked, and I can not access recovery despite entering fastboot mode.

I tried installing several roms by adb, but I could not succeed with any (Always giving FAILED REMOTE).

Yesterday until it managed to enter the initial configuration of the android (where it places the wifi) but then restarted and never again.

I've tried everything a little bit, and I could not succeed with anything.

Help me, please, I do not know what else to do!

Thank you

:confuso:

You have a few options

The first is just wipe the phone and see if it boots
You can do this by putting the phone in bootloader mode (as per your screenshot) by holding Vol down & power button

Then in cmd/terminal window where you have fastboot on your pc type

fastboot erase userdata

Note this will delete everything on internal storage!
Then select the boot normally from bootloader menu


Another option is to flash the entire firmware via fastboot
You will need firmware which is the same or newer than what you currently have
You don't need an unlocked bootloader to flash stock firmware via fastboot

Note fastboot is different from adb - adb won't work in fastboot mode!

My friend, I made the process using the rom of https://forum.xda-developers.com/g5/how-to/official-oreo-8-1-0-opp28-85-16-t3849244 except that excluding the (fastboot flash partition gpt.bin and
fastboot flash bootloader bootloader.img).
Similarly, the screen continues with the motorola logo, does not advance to android, recovery when I select and tighten the power, stay on the motorola screen and back to the fastboot.

The result of the process is this in the image

You need to flash the ENTIRE stock firmware and it MUST be the same or newer than the version already on the phone
Plus you missed sparsechunk0

You got pre-flash validation errors as you are either using the wrong firmware or haven't flash the entire firmware from start to finish

Note if you flash wrong firmware you could potentially hard brick your device

fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img

fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash system system.img_sparsechunk.8
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1 
fastboot erase modemst2 
fastboot flash fsg fsg.mbn
fastboot erase cache 
fastboot erase userdata 
fastboot oem fb_mode_clear
fastboot reboot

I'm from Brazil and from what I've been observing the ROM would be with the same bases as this one from the link.

I refined the process using the command lines you posted and "FAILED REMOTE" is repeated in some lines.

Would not it be some case of partitioning the corrupted system?

Follow the pictures below.

Gpt failed because the firmware you are trying to flash is older than what is currently on your phone

Gpt is needed to repartition your phone and must be flashed along with the bootloader

You will need to download firmware which is equal to or newer than what is already on your phone

I saw there was an October update in the ROM. I will try here in the community this ROM and try to blink and bring the result here ..

 

[sonmota]

friend .. I followed the rom .. I did the whole process (without FAILED) but when it starts up it gets frozen in the Motorola logo.

Any tips on what it might be?

As long as everything flashed correctly and the entire firmware had no errors I'd go into stock recovery and perform a factory reset

Hold Vol down & power button
At bootloader menu use volume keys to navigate to recovery and press power button to select
At the Android screen with no command push and hold power button then with power button held then press Vol up

You are now in recovery mode
Use Vol keys with goto wipe data/factory reset & power button to select


If the rom doesn't boot after that chances are you didn't flash the firmware correctly or there was an error in flashing it due to the wrong firmware used

I can not get into recovery. Would not it be a problem with the motherboard?

Could well be

As long as gpt flashed successfully without giving a downgrade warning which will call it to fail then the recovery part of the firmware should flash and you should have access to recovery mode via entering recovery from bootloader then holding power button and volume up at the picture of the android screen

It could be a motherboard issue but since you have no problem getting into bootloader it's more likely a firmware issue/user error
