(bootloader) could not get unlock data! - Moto E Q&A, Help & Troubleshooting

Hai I have been using Moto e 1st gen for 3 years. I have left my mobile fully charged in a cupboard before 2 months. I found it and charged for a lot of time and it showed me the bootlooder and 0 charging screen. My mobile is rooted and run a 5.1 CyanogenMod os.
I figured it have drained and booted the fastboot menu and charged for a while. It showed that "device is locked . Status code :0". I managed to flash the stock ROM but it didn't because of battery low.
After 3 hours the battey turned green and I was able to run the 'fastboot devices' command. I tried flashing the stock ROM but it's only flashing the partition,Moto boot,logo. Rest of the of the files return "preflash validation failed" .
I think unlocking if the only thing left but I'm getting 'could not get unlock data'... Plz help me and I might have accidentally locked the bootloader during the stock ROM flashing "mfastboot OEM lock begin"
I'm totally new here. If you can help me plz write in detail...:good:

Dead phone

Hello guys,
I'm not a noob when we speak about flashing ROMs and unlocking bootloaders. I've been doing that for some years. Yesterday I flashed the new stock ROM for LG G4 - v29a, android 7.0. Everything went fine. Later this day, I've seen a post claiming that it was possible to relock your bootloader with this specific ROM using the fastboot oem lock. And it worked indeed. The problem now is that when I turn on the phone the following message shows up on RED: "Your device is corrupt. It cannot be trusted and may not work properly".
So, here's the problem:
1 - Can't access recovery;
2- Can't access download mode;
3 - Can't boot normally;
4 - Can't re-unlock since (i guess) the IMEI is now 0;
5 - Can't flash stock ROM using LGUP;
6- Can't erase any partition via adb since the bootloader is now locked;
So, basically all my ways are locked. Any fix you know and want to share?

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

"The System has been Destroyed" after re-lock the bootloader

Dear all,
I bought Mi Pad 4 and it was running well, and I want to update the ROM. The device is comes with Locked bootloader.
I unlocked my Mi Pad 4 using MI Unlock. And when I try to relock it using "fastboot oem lock" command, it become suddenly comes with black screen with written: "The system has been destroyed. Press power button to shutdown".
So I entered the fastboot mode and try some command/solutions:
- My device status is locked:
E:\Minimal ADB and Fastboot>fastboot oem device-info
...
(bootloader) Verity mode: true
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: true
OKAY [ 0.006s]
finished. total time: 0.006s
- I can't unlock it using Mi Unlock:
- Flashing using MiFlashalso not allowed since it is still locked:
- I tried to unlock using fastboot, also failed:
E:\adb>fastboot oem unlock
...
FAILED (remote: Token Verify Failed, Reboot the device
)
finished. total time: 0.003s
- The faastboot screen in my mi pad is only for around 10 Second. After that it goes to "The System has been Destroyed" stage...
Any help is appreciated, because I cant use it anymore...
Why did you even want to close the BL again?!? I dont understand anyone who does that.
And AFAIK you can flash an original Image from Xiaomi even with locked BL. But I have never done it and the guide shows a working phone..
http://en.miui.com/thread-835254-1-1.html
You need the Mi-Flash Tool. And these damn Indian people with their fake titles on youtube.. The title is english and the freaking video is hindi or whatever.. SO ANNOYING!!!
Hi, the tutorial you gave is for 'normal' xiaomi phone, where it boot normally (even its BL is locked).
In my case, I cant load the BL (It said: Destroyed). The only thing I can do is restart to fastboot state, and after 20 seconds it goes again to Destroyed state.
Ok, so I have read some other threads and what seems the "only" solution is to unlock the bootloader again.. But the other people had no problem running "oem unlock".. And you get an error, what is kinda strange.
What happens in MiUnlock? Error?
Hi, I think the main problem is current status is "The System has been Destroyed", therefore it cannot load the BL.
Meanwhile, the BL is in Locked status. So it need to be un-locked first, so I can load the new ROM.
MIUnlock is error, it said: "Current account is not bound to this device", which is strange, because previously I unlocked using it before.
I assume MIUnlock said this because the status of "System destroyed"...
Never lock if there is not 100% Xiaomi official rom inside, and better use MiFlash with "clean all and lock" option for locking.
Thanks for your suggestion. Will do that after I fix this problem..
I think you have a bricked device.. Some devices have this "test-pins", where you can enable some debug-bridge and there you could flash it (mi5 or redmi5 was that in that thread). I dont know if the Pad4 has such Pins and you would have to open the whole device.. (its not something you can access from the outside).
But I dont know if the Pad has these test-pins, just because another Xiaomi device had it..
Noted on that, but too risky for me to open the case..
Any other solution would be really appreciated.

On some devices you have to login your Mi Account with MiFlash when flashing in EDL mode and account needs special permissions.

Yup, and I cant do that since cannot load the BL, because it's "Destroyed" right now..
Up.
Does anyone have the solution on this?
Thanks.
Seemed "bricked" to me, welcome to the bricked world dude, I have had 2 beautiful paper holder on my desk.

The only solution was already posted several times -> open device, find test-pins, use them and flash ROM. And yet, you still ignore it everytime. THERE is no other solution for bricked devices.
And: NEVER close the bootloader again on NON official ROMs.
2 ways to try out...
1st run
"fastboot flashing unlock"
2nd
"fastboot oem reboot EDL"
Or this link if the command doesn't work
https://www.google.com/amp/s/forum....e-how-to-reboot-to-edl-fastboot-t3394292/amp/
go to service centre they will be able to restore the device using edl i hope
I tried also all solutions, but nothing helped. EDL, fastboot, etc.
If there is a way to unlock the BL again I can go on. Otherwise there will be no chance for me to get it running.
Has anyone got a solution how I can unlock the BL again? Or flash with locked BL?
Thanks!

Looks like it is straightforward to remove the back cover. Perhaps you can find the EDL test points on the motherboard?

Is there no possibility to enable USB Debugging without entering the miui surface?

Edl with test points should work, try some different ones, maybe the ones you are trying are wrong

Remote: Token verify failed, reboot device

Hello
Anyone ever seen this when trying to unlock the Note 9 Pro (Joy)?
Im in Fastboot - and the device looks like it's just going to unlock but at 99% of the counter I get the Remote: Token verify failed, reboot device error, the fastboot teddy thing flashes for a second and then back into Fastboot.
Anyone seen that before?
A
PS:- Just thought, when I started the unlock process a week ago I was running 11.0.3 and then I installed the 11.0.4 firmware....would that make a difference?
Just in case this happens to anyone else - the issue I was having was caused by using a different version of fastboot.exe other than the one that came with the unlock tool.
My bad
