Hai all , I am new here.
I need some help to unbrick my device. i tried almost all method and still no luck. the only method i havent tried is DFC, but i dont prefer to do it since its pretty complicated.
My device run rom Global Stable Miui 7 and i flashed Developer rom Global using EDL download mode.
there was an error and now my device stuck in Mi logo. I can still access Mi bunny fastboot ( vol down + power)
So far I have tried 3 methods
Method 1: reboot to fastboot mode, plug to pc, open ADB cmd prompt and type fastboot oem EDL. But no success because device is still locked bootloader.
Method 2: reboot to fastboot mode, plug in to pc, download fastboot EDL cmd from xda forum, unzip then run edll.cmd, device reboot to mi logo again.
Method 3: in Mi logo, plug in to pc, open cmd prompt, type Adb reboot edl, press enter but device cannot reboot to edl mode because it says I need to tap on confirmation dialog on device. But its not possible since device only load up to mi logo
Download the latest stable fastboot ROM from here http://en.miui.com/a-234.html then flash it.

If only it was that easy. I've tried 3 methods above but still no luck. Use Adb reboot edl, fastboot oem.
How to flash if its only stuck at mi logo
Because I had this exact same thing happened before. What I did was while it kept bootlooping at the Mi boot splash I held down Vol - + power until fastboot mode pops up. Then you'd be able to flash.

First off you cannot just unlock the bootloader easily, like in fastboot or anyhow, you need to follow the guides. And this is possible by the way only with a working Dev rom.
Well so now, you've to get miflash tool and flash either stock rom, or dev rom.
You simply hold power and volume down as long (can take some time) as it will show "fastboot" and some android art.
Then you follow the guides to flash either stock rom or dev rom using fastboot, and you're good to go.
I don't see why this wouldn't be working for you, try to stick exactly to what i said. If you don't know how to use Miflash then search at en.miui.com

Did you unlock developer mode as in my case I am also stuck in bootloop and fastboot oem edl is not working as developer mode is disabled thus oem is also disabled.
Hey!
I had the same Problem.
Flashing with Miflash was unsuccessfull and then EDL was locked. You can check this when the device is in fastboot and send "fastboot oem edl". Then there may be the message that EDL is locked. In that case you have to build a "deep flash cable". It is pretty easy. You can check this tutorial:
http://en.miui.com/thread-310325-1-1.html
But I would build it another way: Just cut a USB cable and reconnect all wirepairs with the open copper. Now you can just put "ground" and "data+" togehther and follow steps 7 to 9. At point 10 you can just disconnect the wires "ground" and "data+" again, so that all wires are connected normally again. Now you are in EDL and can flash with MiFlash.
Hello everyone,
So I've read that I can re-lock the bootloadder and tried to do it.
First I have flashed b10 and flashed the su so I wont loose TWRP. I entered fastboot with adb and then I typed fasstboot oem lock, I got a message on the pc with ok.
Since then I cannot boot to the phone.
The phone shows the zte logo for 0.5 seconds but not booting and with constant red led.
Tried power + vol up, power + vol down, all three buttons, vol up + vol down and then connect to pc - nothing at all. The phone wont get past this 0.5 second zte logo.
In all connections I have listed above the phone shows in device manager as QUSB_BULK. At first it was with yellow acclamation mark and then I installed the zadig driver. Now it is connected "normally".
What can I do?
Please refer me to the right tutorial or guide me.
Thanks
I heard that it is not recommended to relock (although possible) unless strict necessity (RMA, sale...) due to risks.
This said, I suggest two methods:
Method A)
Revert back to bootloader unlocked so you will be back as before.
Your current situation with recognized QUSB_BULK driver is good.
Always have Device Manager running to monitor.
- try "adb devices" command. If device recognized: good.
- try "adb reboot bootloader" command: anything changed on screen or Device manager sound?
Then try "fastboot devices" command: if you get answer, then OK you are in fastboot mode.
And in fastboot mode you can now issue the command "fastboot oem unlock" to unload the bootloader again.
Then the phone should be back operational again as before.
Method B)
Try to get to recovery (either stock or TWRP preferably). When the phone can boot to recovery
(TWRP if possible), you are saved since with TWRP you can reflash everything.
Your current situation with recognized QUSB_BULK driver is good for (re)flashing recovery in EDL mode.
Always have Device Manager running to monitor.
- try "adb devices" command. If device recognized: good.
- try "adb reboot recovery": does it boot to recovery?
If not, then my guess is that since the bootloader is locked, unsigned TWRP (as the one you used since normally nobody should use tenfar's signed
TWRP for daily operation) is not accepted.
- so you need to reflash tenfar's signed TWRP mentioned in this guide:
https://forum.xda-developers.com/axon-7/how-to/guide-install-twrp-unlock-bl-flash-t3517379
using EDL mode ("adb reboot edl", then "axon7tool -w recovery" etc..., with file recovery.bin = tenfar recovery).
tenfar's signed recovery is accepted even if the bootloader is locked.
- after that you should be able to boot TWRP (tenfar), by using 'adb reboot recovery', or with Power + Volume-Up: your phone is now under your control!
(reunlock, upgrade TWRP, flash ROM, root...)

I'll try to do it but yesterday tried to go to edl or recovery in cmd no device found. Tried to flash recovery but it hangs on "waiting for device" so I don't thing I can get to these edl, recovery, fastboot status.

So for sure I'm doing something wrong. Can you please guide me with this tool?
Ironically you helped me unlock the bootloader and I need your assistance relocking it.
Edit: I have the 3 files backed up from the unlocking procedure they should help no?
The phone is not recognized in any adb status edl or fastboot
I don't think you can have a modified recovery partition and a locked bootloader. As I understood it, fastboot oem lock will fail or result in brick if you try to flash anything other than authorized files. Can anyone confirm that they have successfully locked their bootloader and retained TWRP?

I don't want to keep twrp or anything. I want to sell the phone so all I want.t is to go back to locked stock phone.
I cannot boot to recovery or fastboot or edl. If I could I would use miflash and flash b10 and be done with it
I think that the initial problem arose when you flashed SU and tried to relock the bootloader with TWRP installed
What does Windows Device Manager show when you connect the phone to your PC?
Update: sorry bud. I totally missed that bit in your OP. DOH! Will update.

https://forum.xda-developers.com/showpost.php?p=70948893&postcount=28
Sorry that I can't be of more help...
I think what went wrong with my device is that after flashing stock b10 I flashed su so I won't lose twrp. Now when I tried to lock the boot loader made a conflict as I could not have locked bootloader and this version of twrp (for unlocked device). Now I just need to find a way to flash stock recovery (I have a backup from the unlocking procedure) without edl or fastboot as I cannot seem to find a way to enter these states (cause I have no recovery) I'm hoping it makes sense (pretty early in the morning)
So no one can help?
I can't believe the phone is beyond repair
@ItsNewDroid
Sorry I do not have solution, just some idea.
It "seems" that you cannot boot to either system, recovery, bootloader, EDL! adb/fastboot commands are not recognized.
There is still hope since your phone is still recognized somehow as QUSB_BULK (not unknown device) with Zadig driver under USB device.
So you can try to uninstall Zadig WinUSB driver and use Qualcomm bulk drivers so that the phone appears under COM port as Qualcomm HS-USB QDLoader 9008.
If you get 9008 then you are in EDL mode, and MiFlash could be used to flash.
Qualcomm bulk drivers, MiFlash... are available from Download center:
https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547
The problem is to find available "EDL packages" recognized by MiFlash to flash.
These packages could be stock recovery, signed TWRP, or full ROM (any version, MM, or Nougat).
This would allow booting to either recovery or system.
The problem is that I did not see many such packages for A2017G, but only for A2017U.
You may have to ask other members how to build such "EDL packages" (for ROM, sometimes it is called "fastboot ROM").
@dnlilas
First, let me thank you for your help. It is much appreciated.
I've uninstalled the zadig driver and installed Qualcomm driver. Now the phone shows in device manager under ports - (DFU) (COM 4) not as Qualcomm HS-USB QDLoader 9008.
Do you know the steps to enter Qualcomm HS-USB QDLoader 9008?
Thanks again

Edit:
Miflash is not recognized in any key combination.
Edit 2: So somehow I booted to fastboot. My boot loader is LOCKED!! What to do now?

Man there are changes!
So somehow I booted to fastboot. My boot loader is LOCKED!! What to do now?
Excellent! Try to remember how you get to this menu.
Does "adb devices" command recognized? Status "xxx recovery"?
Of does "fastboot devices" recognized? If yes => you are in fastboot mode. Then you can try to unlock (reverse lock operation) with:
"fastboot oem unlock"
It should ask on phone to erase data (like factory reset). Then say yes.
Edit: the screen capture you took is the bootloader menu (equivalent to come into with "adb reboot bootloader").
When in bootloader, I believe you can use Volume-Up and Volume-Down to navigate (to go to recovery, system, bootloader or other mode). Validate with Power button. It is important to remember how to get to this bootloader menu.

I held the 3 buttons not connected to power or pc. As soon as I felt the vibration before zte logo I let go of the vol up button and it booted to fastboot.
I dont want to unlock the bootloader I want to sell the phone ( this is the reason I came to this situation) I tried to boot to recovery from this menu but it could not.
My guess is that I have twrp recovery and as the bootloader is locked it can not boot.
I need either a twrp for LOCKED bootloader or a stock recovery.
I'm searching the forum but could not find.
You are a wizard! Every time you reply I have good news :good::laugh:

Download tenfar's signed TWRP here:
TWRP 3.0.2.2 (tenfar) : https://www.androidfilehost.com/?fid=529152257862720446 (download center https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547)
Important: check md5 6eeb1a9d02470a840bc68019184d9a72
A2017G-TWRPrecovery3.0.2.2tenfar.img
to insure correct download.
Note: tenfar's signed TWRP can be flashed even with locked bootloader, using fastboot in EDL mode (bootloader mode).
Important: I believe you need to switch back to Zadig driver first so that axon7tool used below could work.
The most important thing is that "fastboot devices" command must be recognized while you are in EDL (bootloader) mode.
In the directory where resides axon7tool (axon7tool-1.5-win64.exe https://forum.xda-developers.com/axon-7/how-to/guide-install-twrp-unlock-bl-flash-t3517379),
make a copy of it with the name recovery.bin:
copy A2017G-TWRPrecovery3.0.2.2tenfar.img recovery.bin
Put your phone in bootloader mode (EDL mode) as before, then verify that "fastboot devices" command is answered correctly with your device id.
If OK, then issue the command:
axon7tool-1.5-win64.exe -w recovery
If everything is OK, this will write tenfar's TWRP signed recovery and phone reboots (I believe so).
Immediately Use "Power and Volume-Up" until ZTE logo: it should then boot in recovery (TWRP, tenfar version 3.0.2-2).
Good luck to you!

So this is the new situation: adb devices phone is not recognized. Fastboot devices device IS recognized. Issuing axon7tool - w recovery I get device not connected failed to connect. Any idea?
How can I relock the boot loader and restore my Stylo 2 to factory default? Provider is T-mobile.
fastboot flash oem lock.
Note however if you used twrp this will brick your device unless you flash the original recovery first. Provided you got the kdz or LG bridge you should be able to just lock put in download mode and use the repair recovery option.I'm not responsible if you brick your device. Good luck

I had used LG Bridge to reflash my phone so I believe that I have original recovery on the phone. How can I verify?
When I enter fastboot flash oem lock I get < waiting for device> on my terminal screen and thats it?
Once you have the phone wiped completely back to default (including recovery) with the LG tools. Enable developer mode, and then enable USB debugging. While it is plugged into your PC navigate to the folder where you have the ADB applications in CMD or add the location to your Environment variables. The latter will allow you to launch ADB/fastboot commands from any location in CMD. I definitely suggest this. With your phone connected run "adb devices" to make sure that it sees your device. Then run "adb reboot-bootloader" to reboot into the bootloader. While on that screen run the command "fastboot flashing lock_critical". It should prompt OKAY then give the time it took and also that all of the user data was deleted. Then finish up by typing "fastboot reboot". That will put the phone back into a normal mode. Boom, you are done.
Help
When I use the fastboot oem lock, at the moment when I power on the phone in the screen appears the text "Your device has failed a routine safety check and will not boot.
This may be a temporary problem.If this message occurs rerepeatedly, visit this link on another device and refer to the Red case: g.co/ABH

Ok thanks I will send it in to a shop where someone can do that
Connect phone to pc, start adb on pc...put phone in fastboot mode ( press volume - and power ) , type in adb
fastboot continue
After command, phone will reboot and boot system.
After that , you add mi acc and start unlock process.
If you reboot phone, you need to do this step again.
When you unlock bootloader, flash official rom or xiaomi.eu...
You could flash official xiaomi fastboot rom with Miflash tool: this flash recovery and MIUI also with BL locked.
Then you'll use miunlock tool to unlock bootloader
GGelmi
did your problem solved?
Hi,
i used Miflash in edl mode to get back to stock rom. after flash and reboot I used the recovery mode to do a factory reset.
It seems to work. It shows Android Recovery, but the bootloader is still unlocked.
What mode do I need to enter to use the "fastboot oem lock" command? I always see "waiting for device" and nothing happens
When I type "adb devices" I can see the phone. I saw there is a command "fastboot devices", too. but it shows me no result.

That doesn't work. The phone isn't entering a special mode. I can choose fastboot from the bootmenu, too. But nothing happens. The phone does a restart, shows the bootmenu again and boots android after 5 seconds.
@Stevie123
You need to enable fastboot (bootloader) mode since it is disabled by ZTE, so that the selection from menu to be effective (after enabling it, in fastboot mode, your command "fastboot devices" (to check) and "fastboot oem lock" (to lock bootloader) will be accepted).
You can use Axon 7 EDL tool to unlock the bootloader.
It's already unlocked. I have to make another unlock procedure again to get access to fastboot? The EDL Tool tells me that I have to wipe and reset the phone after it. So it seems I can't keep my data and just lock the bootloader.
Either Lock or Unlock will wipe your data. And yes, the unlock procedure by Axon 7 EDL tool includes the enabling of fastboot. So you have to re-unlock if you want to relock.
I think this EDL tool doesn't work very good. It flashed something to make fastboot available, but I had a green ZTE Logo screen and this screen also had errors like white spots. The original ZTE logo is in cyan. But the fastboot worked and I could lock the phone. But I couldn't do anything else anymore. I couldn't reach Android and reflashing also didn't work. So I tried to use the EDL Tool to unlock my bootloader again. It said success, but it didn't work. It was still locked.
Well, I had to wait until the phone was empty. Luckily I could reach EDL Mode again. I used the MiFlash again to Downgrade to Android Nougat B12. I read somewhere that the fastboot is included there. So I had the right ZTE Logo back and it worked. I could leave the Bootloader locked. The final update I did with a SD Card to the lastest Android Software for Axon 7. Luckily without a brick. It's a pity that they don't offer any Updates anymore.
