Moto G4 needs help Unlocking Bootloader - Android Q&A, Help & Troubleshooting

Motorola G4 XT1625
Minor Problem: Phone will not start normally, only boots into Fastboot mode.
Minor Problem: Phone is oem Locked
Major Problem: I never went into "settings" on the phone and ENABLED OEM UNLOCKING.
Question: Is it possible to get this phone flashed with stock ROM?
A little background. Not a developer, phone started acting up a few days ago, shutting down or rebooting on its own, do not remember anything such as an update or my clearing of the cache occurring in that time frame, but I was still hoping it was a software issue that would work itself out. Now the phone fails during start up and reports this
STARTUP FAILED
ERROR: Failed to pass validation , backup to fastboot.
It does mention I should use Software Repair Assistant to recover the phone, which correct me if I'm wrong , only works with Verizon phones. I did try the SRA, it connected to the phone, but would stall about halfway through.
I have found much info on this forum regarding unlocking the bootloader of this phone, I have installed on Moto tools on my PC, requested and received an unlock code, connected to the phone and can send commands via command line. Unfortunately when I send the oem unlock the phone responds that I need to enable development mode in settings, which I cannot get to because the phone wont boot to the OS. Is there an easy way around this that I'm just not seeing?
In the end the problem may be hardware related, I just hate to give up on it so easily. Contacted Motorola about the device, as it turns out the unit was 6 days out of warranty ( that's if you use the Amazon ship date, it was only actually 2 days out if you use the activation date). Their response was as expected, sorry can't help you, thanks for being a Motorola customer, have wonderful day, next........

Moto Z bricked OEM Locked

Hello friends of XDA, I have a big problem between hands, I have a MOTO Z and I had it in android 7.0 since last year the update to andorid 7.1.1 did not arrive and I felt that with android 7 the battery was consumed very quickly, so I tried to find the update to flash it and just about 3 days ago I found it, I proceeded to download it and flash it in fastboot and adb.
The thing is that a few months ago, browsing through my phone (I had already rotated it, and unlocked the bottloader, I decided to re-block the bootloader, and remove the root, which never worked at 100) I got into the developer options, and I saw an option that until then I didn't know about its "OEM Unlock"function, as it was turned on and deactivated because I thought it didn't work.
Returning to the update flashing I proceeded as usual, with the commands, I proceed to restart the device and show the image of the boot of motrola but then it shows me a message in red letters.
"Startup Failed"
"failed to pass validation, backup to fastboot.
I thought it was a compatibility problem with the downloaded version of 7.1.1 so again I decided to flash the stock rom 7.0 but when I finished and restart the same message appeared.
I started to investigate and it seems that the OEM blockade is responsible for not being able to install any Stock Rom, or anything, and now I have a nice brick with Moto mods and I can't use it.
I wanted to unlock OEM in fastboot but nothing. sends message from "ALLOW OEM UNLOCK IN SETTINGS"
There is way to unlock the OEM from pc or fastboot without needing to be unlocked from the android settings, as in my case it is impossible for me,
I'd be very grateful for your help friends, I know it's a bit tedious to read but it's the only phone I have and I feel weird without it on the street.:bueno::bueno::llorando:
I'm with same problem here!

Try to boot in Fastboot flash twrp and flash ressurection remix rom. It's great rom. Forget about locking. I had the same problem like you as I was trying to flash stock ROM and lock bootloader.
I gave up on this.

Well, when the root didn't work properly, I flashed the phone again and blocked the bootloader. Will I still be able to install TWPR or should I lose my phone?

What do you mean with "I blocked my bootloader"?
Twrp is easy to flash. Root is integrated in ressurection remix rom. And this rom is great. Just try to flash twrp in Fastboot and than ressurection remix with twrp.
Can you boot in Fastboot?
Do you remember what build of 7.1.1 you had on your device before downgrading to 7.0?
If so, I would suggest finding that firmware (the full stock firmware, not OTA updates) or newer if you can, and try to flash that. Since your bootloader is still likely from the 7.1.1 build, a locked bootloader will only permit files matching the same patch level (i.e. from the exact same stock ROM as that bootloader patch) to boot.
If not, then unfortunately there's not a lot we can do. You could wait for a newer firmware to get leaked, but as your device is unable to boot (due to failing the bootloader checks) and you cannot toggle OEM unlocking because you cannot boot, it's a nasty vicious circle that is difficult to get out of. You may have to consider sending your device for service and pay for an expensive motherboard replacement otherwise, since Motorola have a record of your device being unlocked. Your service centre experience may vary.
Only lock a bootloader after ensuring you've flashed all the stock firmware and it is all the same patch level as your bootloader. Hopefully you'll find newer firmware that you can repair with.

I solved it, I finally flashed the stock rom to my phone and it works.
Apparently my pc was not flashing the stock rom in adb, and the phone turned off when loading the software. I did it 3 times until I load correctly and start well.
if you have the same problem apparently then OEM Blocking is not responsible. You have to flash the most current rom or the one that you had by default when the brick happened to you, you flash it in a normal way with commands of adb and ready, I would have to come back to life.
download from firmware center MotoZ Griffin the most current rom stock at 7.1.1

Thanks for your help friend, I finally flashed it with a recent android 7.1.1 update. Apparently the OEM lockout was not the culprit, but it was an interrupted flash of android 7.1.1 at some point when loading the software to the phone, it would shut down on its own and not complete the installation, which showed me the mentioned message. I didn't realize that and thought it was the OEM blockade.
I finally did it on another pc and it worked. the phone came back to life.
I have one Moto Z2 Force (XT1789-05), bought from coolicool.com, I didn't know device came Unlocked Bootloader, Device rom had problem with many apps, I googled and found one topic in XDA developer to Install Stock Rom, I downloaded and Installed India Rom, it's worked somehow fine, but still had problem, I downloaded Verizon Rom, Android 8, after Installed Android 8 Verizon Rom, Locked device bootloader immediately, now device stuck at Welcome Wizard in Android 8, after select language I got this message: (Please wait, this may take a few minutes) this is proof video (http://ahmn.co/Upload/IMG_0161.MOV), after this issue, device already locked, I can't unlock, because need to go to the Developer Option in Setting, I stucked in Welcome Wizard, there isn't any bypass, So, I start to search in Google, XDA-Forum, Android Central and more, I created many threads, many requests, no one can't help me, I tried to reach google developer support to the tell to me how can I bypass Android 8 Welcome Wizard, there is must be a way, but I can't find it, now I can access to Android Recovery and Bootloader
1. if you help me to FORCE UNLOCK device without need Developer Option in setting my problem will solve
2. If you help me to Bypass Android Welcome Wizard, access setting and enable OEM Unlock
3. If you help me to update the device from Android 8 to Android 9 Verizon ROM via ADB Sideload or Update from SD card in Recovery mode
4. If you have any idea to how can I fix it
Extra Information: I bought Belkin and Uni USB-C to Ethernet Adaptor to help me bypass Android 8 Welcome Wizard, I bought WSKY WIFI Adaptor because device Wifi can't find any network (I found QR setup by tap several times in Language Selection), after this section need to download google device policy apk, my device can't find any Wifi Network and my Ethernet Adaptor can't help me either, So, I just remained with my phone, and I can't do anything,
Please, someone, help me

unlock bootloader: yes! but unlocking seems impossible...

hi!
after reading all related post in this forum and searching google for ages, i am still not able to unlock my z5c's bootloader. it is not a lack of skills or know-how - i have successfully unlocked my z1c and z3c - but this one simply does not unlock.
i have tried both windows and linux, used shell and flashtool, all drivers properly installed, phone is correctly recognized, bootloader unlock is positive, oem unlock and usb-debugging are activated, phone is in fastboot but i still end up with error "command did not succeed". flashtool additionally shows "oem unlock not activated?". it is, but doesn't seem to have any effect.
i also tried to include the .txt file with the unlockcode into flashtools filestructure: flashtool does something but can't finish the unlock proccess and my phone is not resetting.
i even tried those one-click unlocker without success.
and there is something fishy about this phone: three month ago i got it brandnew from a vendor in china via ebay and first thing i did was connecting it to the pc companion to upgrade the firmware which was 5.1 and it told me, firmware was up to date... so i tried the repair option and it told me "that due to it's prototype status it can only be upgraded from certain ips" - although the phone does not show any hints of being a prototype, neither software- nor hardwarewise and even if it was, it wouldn't prevent the bootloader from being unlocked (afaik).
so you guys are my last hope! any further ideas???
regards,
andi
Hmm... Possibly not the solution but have you tried enabling "Unknown Sources" as well?
Another thing is - you can try flashing a later version of the firmware with Flashtool - one that is common. Afaik there are some versions that have trouble unlocking. Try flashing something like Nordic Unbranded, boot it up, make the settings again.
P.S. Flashing does NOT remove the old leftover firmware - it just writes on top. So you should format the partitions (/system, /data, /cache, /dalvik-cache) before flashing in order to start clean.
when i couldn't upgrade the firmware via pc-companion i used flashtool to flash 7.1.1 (some german version) which i kept ever since. so flashing a different firmware before unlocking is something worth trying? i thought of this as well but never actually tried it because i was just too lazy going though all the setup process again if the attempt failed just like the others... but i'll give it a try then!
and thanks for the input!
Hy,
For me i had to make two steps :
- Flash a non-branded firmware from Xperifirm
- Network unlock it (actually for me it unlocked automatically at the end of the warranty ). This step it is critical (as i was informed in the Sony store)
Then the normal cmd command through adb worked fine.
Basically for me the network lock / warranty was the issue that prevented me to unlock the bootloader
thank you very much for your Input! but there is no network lock...
what i was going to do was flashing a different firmware and try again - and there is something else i didn't think of: the usb2 connector of my mainboard is blocked by an infrared device to power up my pc by voice command via alexa and a harmony hub. and to still be able to use the front usb ports of my case i connected them with an adapter cable to a free usb3 socket on the mainboard…
so it might have been the firmware, the usb2 port on a usb3 socket or prototype-status that caused the trouble - but i'll never know cause basically i'll give up on that phone since more issues occured… i contacted the vendor yesterday and it seems i'll get a full refund!
i now got my hands on a shiny new galaxy s7 and hopefully i'll experience the joys of oreo 8.1 and lineage 15.1 anywhere soon without the hazzle!
thanks again for your help and regards,
andi

Moto G XT1540 bricked forgot to Enable OEM Unlock

Hello,
Let me tell you my story and perhaps someone will come up with a miracle solution for my problem.
I was trying to flash my device so: I opened developer options and enabled enabled USB debugging.
I though this was enough, but in the middle of the process I got some errors like "Preflash validation failture". So I went back and discovered that I had the fastboot locked and that in order to unlock it I should get a code from Motorola. I got the code, but when I was going to unlock it, I got another error saying that I can't unlock my flash boot since I didn't enable the check "Enable OEM Unlock" and at that moment was when I discovered I was screwed.
Someone said, that I was just a matter of downloading a Stock room, and repeat the process but I have downloaded tons of them and no luck.
At this point, I would try anything just to be able to open my phone in recovery mode because I can't do anything with it is dead,
I have read tons and tons of posts and all off them lead me to the same point, flash through fastboot repeat all the commands, but I have been there almost 100times. I'm about to get crazy.
If someone knows something, I will really appreciate it.

Xiaomi Mi Play -bricked by official update

Hello All,
Hope you and yours are doing fine in these worldwide complicated days.
Regarding the subject, I have a Xiaomi Mi Play mobile that was working fine, with official MIUI, never rooted, never done something else than usual "office" daily usage.
One day, came the famous Security Update notification and as usual, I've confirmed.
Since then big headaches...
Next morning I found the phone in the loop reboot, Fastboot being the only available feature, no more recovery, no more OS, no more personal stuff... Everything has been deleted by the update.
When trying to go to recovery only the magnificent message with the red triangle, saying "The system has been destroyed. Press the power button to shutdown" stays for 10-15 secs and then the whole crap reboots again and again.
No, Developer Settings haven't been enabled, OEM Unlock has not been enabled, USB Debugger neither, bootloader has not been unlocked, MIUI account has not been added in Developer Settings or elsewhere... and no I haven't wrote to Xiaomi support yet.
I've tried around 60-80 different methods to unlock whatever could be unlocked on Xiaomi phone, EDL, bootloader, with dozens and dozens of methods proposed, so far nothing worked. Impossible to install anything, impossible to unlock anything, impossible to do anything.
I've applied for the phone unlock, but since 2 months, impossible to finish the process, it says "Couldn't Unlock - Please add your account in MIUI's Settings > Developer options > Mi Unlock Status"
But I CANNOT access the system anymore at all....
This is it...
Thank you for reading and if you have any other ideas out of everything I've tried, feel free to let me know about.
Take care of you and yours
Kind Regards,
SK
ooophhh no. did you ever get a solution? i had my mi play brick just oputta the blue.. its on communist lockdown fighting the war on capitalism ..... well the hardware wasnt bad for the price and it ran well.,but im not buying a phone from them ever again.
It's very sad. Did you get any update?
Hello All,
No update since March, still looking and trying to unbrick the device....
I'll keep you posted if I find anything that could be called a solution.
Thanks for your support.
Be safe all, you and yours.
Kind Regards,
SK
Same here, bricked device since March by the same update, "The System has been destroyed", fastboot doesn't load.
I guess i've lost 150$.

There are many thread for issues like this, for example:
https://forum.xda-developers.com/mi-9-se/help/lock-bootloader-destroyed-help-t3965825
It seems that in some way, same issue was fixed on a different model, but most likely it will work also with Mi Play.
Af far as I have understood, basically the solution is to download the official firmware and flash it back. The main issue is that by default the bootloader is locked so nothing can be written. The point here is how to unlock the phone, and there is an official procedure from Xiaomi:
https://forum.xda-developers.com/mi-9t/how-to/guide-unlock-bootloader-flash-xiaomi-eu-t3952443
I have the same issue for a couple of hours and I am struggling now, so as first step I am trying to unlock the bootloader, but the problem is that per Xiaomi instructions it may take up to 7 days.
So, I will apply for that, while in the meantime I will look for any alternative solutions (if any).
Regards,
Thanks a lot!
But, the're now way to get my phone into fastboot mode.
I've tried all button combinations and there's no response, just the same loop "your system has been destroyed"

After some tests on my device, I have found out that it's not easy as I have believed, but if you don't get even in Fastboot mode it's more complicated.
However, can you please clarify what's your cellphone model?
Regards,
I have exactly the same problem since early May, if I just unlock the boot loader before they fall down :c

Question TMobile variant won't stay in fastboot

Ok , lemme cover my bases here... OnePlus 10t, Android 12, T Mobile. .
I have usb debugging on, oem unlock on, and device appears in ADB ... Newest platform tools, updated drivers.... When I run 'adb reboot bootloader', the phone shuts off, then I see 'fastboot mode' for like half a second , and it goes off and boots up normal. I can enter fastbootd .. but regular fastboot causes instant reboot! Can ANYONE help me with what I need to do? You can't unlock bootloader in fastbootd... So I need help figuring out how to make it NOT kick out of fastboot when I enter the command. (Usb 2.0)
OPPO locked the bootloader permanently. They do this on the find series as well.. basically bootloader mode is disabled.
I haven't heard about this before, is it a T-Mobile only thing? That seems really bad for oppo to do that...

ok , so how then can i either re activate this mode or root this device? because that is a deal breaker for me! I wont keep the ONLY model of this phone that has Fastboot disabled, and therefore is unable to be rooted! I have about 8 days left to package back up and send back to Tmobile for refund! Now i can fully reach EDL mode, so if there is a software that can let me flash the EU Unlocked FW , then please direct me. I saw some success written about here with the new MSM, but it requires some authentication. I am 100% fully committed to any method, no matter how complex, to rectify this travesty! The ONLY reason i jumped from Samsung to OnePlus years ago was because of how Developer friendly they were... Easy unlock of bootloader... yadda yadda! Now the curse of Beatbreaker has struck again, and the impossible has happened in that SAMSUNG bootloaders are now easily unlockable via purchased token... and Oneplus has become part of an asshat dictatorship.
Please advise if there is ANYONE here who can either help me with this situation, or can direct me to instructions/software that can flip this situation around. I mean, the fact that Fastbootd reports my device in "Fastboot" when running 'Fastboot devices' ... AND that even if only for a glimpse of a second i can see FASTBOOT MODE, before it kicks me out and reboots, tells me that there must be some glitch, exploit, or workaround that can re-enable it! I only state this because some phone companies (carriers) like Metropcs were pre-installing FW that made Download mode disabled for quite a few devices, but thru some low level (edl) actions, we were able to reverse that and load a global fw to the phones, restoring all functions!
ok long posts.... ANYONE... I am up for ALL suggestions, because i can fully brick this phone and return it , but my window closes in 7 days!

Dang! This is a messy situation for yah! I contacted support for an MSM tool and they said I have to send it in for them to flash it.
I think trying to have them flash some other variant would take you past your 7 day window and they may not do it anyways.
I would say least send an email to OnePlus support and ask if they would flash to other variant otherwise you will be returning the phone. You should get a response soon. Otherwise I'd lean towards returning it... Sadly.
Then buy straight from oneplus if you still want a 10t. They may have a good blackfriday deal on this phone as well.
