Moto g5 hard brick - Moto G5 Questions & Answers

After installing security update with the unlocked bootloader my Moto g5 went into hard brick, wanted to know if there is any solution, I already tried to look for the flashbak of Moto g5 but not find there is any repair method?

Only solution is a new motherboard or a repair shop with equipment to reimage the bootloader eg j-tag (such equipment costs about double the price of this phone to buy & requires knowledge of soldering pins etc so cheaper getting repair shop to do it)

I decided to just forget about my dead device. I can't sell it (for pieces) because it still contains my data inside. I will get something with better development when I get enough money. It wasn't a bad device, but it didn't really match my development needs.

RIP.

you think that with a j-tag it is fine, I mean that if it can be repaired because I understand that it is not the bootloader that is deprogrammed but the boot itself.:confuso:

Since I don't own one or tried I can't answer this question
A j-tag can be use to re-image a phone with original firmware if the phone cannot enter the bootloader

then you think it's possible to repair it with a j-tag to take it to a workshop to repair my phone.
or better I wait for them to filter the blank flash files

You could be waiting years for blank flash files - they are leaked
They may never be leaked
Choice is yours

so what do you suggest me do?
I take it with a technician to see if they can repair it with a box or with the j-tag or I hope the truth is that I do not know what to do.

Save money and buy a device that suits your needs better than this one. Sell your dead Moto G5 for pieces, since I guess the other components (screen, camera, speakers, USB port, battery, etc.) still work. I'm sorry, but there's nothing else you can do.

For now has no news, alias Moto g5 has not even 1 year of launching it will take to be leaked, the only solution for now is a technician who knows how to mess with JTAG or the motherboard exchange, it is possible that the for the May be leaked alo

this phone has more than a year that went to the market that was in February 2017 and not only is happening to this terminal but also to the successor to the motorola g5s and I do not think it takes so long to leave the blank flash since on the moto g4 / plus and moto z2 play came out before the year of being on the scoreboard.

Olá Ebner no momento não existe esses arquivos, celulares como Moto G5 plus já existem arquivos QFIL ou o firmware do flashbank, isso pode demorar pois é algo que a Lenovo não vai soltar, e só é lançado se for vazado ou criado pela propia comunidade, tem só dois meio de solução no Brasil, conserto via JTAG que custa em torno de 200 ou o conserto da placa que custa em torno de 600 reais, caso você tem hardbrick sem desbloquear o bootloader a Lenovo cobre todos custo de reparo, espero que tenha ajudado

Estou perguntando somente, meu k10 ainda está chegando por isso não tentei ainda, mas no meu Z1 ele funcionou com Locked Bootloader com a ultima versão do Kingroot, somente. Por isso estou perguntando se alguém já tentou. Em outro tópico vi um ou dois falando que funcionou.
Como eu disse, só não testei ainda porque não to com o celular em mãos, mas é a versão que tá no site oficial, porém estou com receio no caso de um brick...

I dont know man , it's because Kingroot works in cell (in case my Z1 worked without any problem) with locked bootloader so I'm wondering if anyone has tried . Or can try ...
yes and no
no lg k10 420n funciona com o bootloader desbloqueado mais com o kingroot versão pc. agora para os outros k10 android versao 6.0 so funciona desbloqueando o bootloader e com a criptografia de fabrica desativada, ai da para rootar pelo "V2+DP+ROOT.exe". o problema e que ainda nao encontrei como desativar a criptografia de fabrica
in lg lg k10 420N works with the bootloader unlocked more with kingroot version pc. Now for the other lg k10 android version 6.0 only works unlocking the bootloader and encryption disabled manufactures, woe to the rootar by "V2 + DP + root.exe". the problem and still not found how to disable encryption manufactures

I don't know if you can get to what's known as EDL mode on the Axon 7 but it's worth a try, Hold both volume buttons in and plug into usb, you'll need the Quallcom usb drivers installed on your PC.
If after plugging in the phone and holding in both volume buttons, you can let go after plugging in, you go to My computer and right click thewn go to manage, device manager and check ports. If you have got into EDL mode then you'll see a quallcom usb device 9008 displayed ( vsomething close, can't quite remember).
You may be able to use fastboot commands from there but with the Axon 7 I used miflash to install the stock rom.
Not sure if this may work or not but may be worth a try...
The phone is in edl mode but I can't find the raw firmware to flash it I need the firehouse rawprogram0.xml and patch0.xml but I can't find them anywhere
Can the phone be detected in ADB or fastboot?
You need to download ADB and install, open a cmd window from the ADB folder and type "ADB devices" It will show your serial number if it is there.
Or you can try "fastboot devices", again showing your serial number if it is detected.
I haven't had to do this as yet, luckily, but you should be able to flash the rom from fastboot or ADB (you will need to search for how).
Hope this points you in the right direction...
Hi, i have same problem, my phone is hard bricked, my pc detect it only like qualcomm hs-usb qdloader 9008, i have read that there's a program QFIL that can flash bootloader etc but i can't find the necessary files! every one can help me?

ok boys i did unlock my bootloader then rooted , ok .
but i did reinstall the stock rom without root , then one update did come i installed now my phone dont boot only when i plug on charge the led comes flashing
nothing happens i plug on PC except the flashing frontal led
anyone know what can i do ?
To update official stock rom with bootloader unlocked you need a custom recovery, if you have the stock recovery your bootloader partition gets corrupted and you can't boot the phone. This happened to me twice, luckily, I sent the phone to warranty and they replaced the motherboard.
Which stock ROM did you flash? If you flashed an older stock ROM and attempted to use OTA updates, then you may have corrupted your bootloader with the older OTA update. That's a hard brick, usually requiring a blankflash. I've not seen one for Cedric or Montana devices, and blankflashes are generally leaked from Motorola (Motorola will not likely give you one).
Unless you can make/find an image of a working device, a loader image, then the other option is to submit your device to service. You may be lucky as Ramonms2 and have your motherboard replaced under warranty, but depending on your service centre and local consumer laws, they may bill you for the repair.
Attempting to use OTA updates on an older system but newer bootloader (and bootloaders do not appear to be downgraded) is what appears to cause a lot of bricks.

Hopefully they'll repair your device under warranty, however there is a record against your device IMEI that indicates you've requested the unlock key. As that request voids the warranty, be prepared for the possibility you may have to pay for the repair depending on what they find.
Good luck with the repair regardless.

alghuien logro solucionar el fullbrick de moto z2 play
Si tu moto Z2 Play hicieras lo que hicieras tratando de modificar el sistema se te apago y solo cuando lo conectas prende el led nosotros te enviamos un archivo de manos de 1mb que lo sacara de ahí. Es el Blank Flash, Investiga en internet y veras que hay cientos, este nosotros lo programamos y en menos de 20 segundos tu teléfono encenderá de nuevo. Lo enviamos por email
Did you hard Brick your Moto Z2 Play, We have the only Blank flash that Will boot your cell in less tan 20 seconds. (No screen just blinking led when you plugg it )
Review what is that blank flash, is not aviavle any whare because we program it.
SOLUCION YA !!! (Siguiente Link)
How I solved mine
To be direct, as honest a posible. I just went into AT&T, and my warranty was able to run over the phone. I know, I unlocked the Bootloader, I clearly voided warranty, and Motorola was even aware of that, somehow, due to maybe how the warranty runs with AT&T they finally replaced the main board.
Whenever your phone gets into the QUALCOMM Modem Recovery, is pretty much death, if you do not have a Blankflash for the specific OS, Model, and Bootloader version. But if you got into the problem, without voiding anything your chances area way better then, and maybe just give it a shot.
Or, If you are already outside warranty, It may be the end. Unless a Blackflash for Oreo gets out, that's the only way to actually unbrick these phones, and Motorola is not that good to just going ahead with everyone having the BlankFlash, since that file, can unlock any phone and that means stealing being easier for that specific model.
That's actually my suggestion, if you have warranty; maybe inside a carrier, just go and try.

1. Never relock your bootloader. That's a good way to brick your phone. You never need to relock it to take OTAs, you just need to flash your stock firmware.
2. You can try the command fastboot -w
If that doesn't allow your phone to boot up afterwards, you need to flash your stock firmware. If your stock firmware refuses to flash, you're bricked.

Just as @Spaceminer and @sd_shadow have correctly noted, the "bad key" notification you are getting is not an error of any kind. It is synonymous to Motorola's legend "WARNING: YOUR BOOTLOADER HAS BEEN UNLOCKED" logo screen seen on older Moto devices. Motorola does not sign the majority of their firmware packages (the LMSA device recovery firmware packages are signed by Motorola, as @sd_shadow has noted). So, any time you flash the /boot partition with an unsigned image (and/or the /recovery partition on non-A/B devices), you are going to receive the "bad key" and sometimes the "N/A" notification. But again, this is not an error notification. It merely indicates that you flashed the /boot partition with an unsigned image, which is permissible on oem unlocked devices. @sd_shadow's link above is an excellent guide on using LMSA, with download links for the LMSA utility and device drivers.
