I have tried to unlock the bootloader of my phone using the potatonv tool. The problem is that I now cannot get out of COM mode and I cannot reboot the phone by pressing any of the buttons.
I can confirm that they all work though, and I tried rebooting the phone by using the potatonv tool without the auto reboot clicked, and every time I try to get code again I get a different bootloader unlock code.
I then would get into recovery mode with it saying phone unlocked but I saw no confirmation message on my phone saying to unlock the bootloader as seen in all those guides that were searched online. I tried to flash pixel experience using the link provided here but its download link directed me to the github link with multiple downloads which I do not know which to choose from. I tried to flash twrp but it gives me an error
FAILED (remote: image verification error)The xda link for the TWRP from 2017 has also expired. Can anyone help?
Mod edit : TG links allowed only for own development threads.
Btw I'm using PE+ A12.1 recently it's good

Hi,
My Nexus 6p was running the latest OTP update of Android Nougat successfully, Suddenly while using google maps it, restarted and went into a boot loop. All i can see is the unlocked bootloader warning (i had unlocked the bootloader earlier) and then the google logo.
I am able to go into bootloader mode and my system identifies my device as a fastoboot device .
I was able to access my stock recovery but while trying to fix my phone, i tried installing twrp recovery and now whenever I choose the option of recovery mode using my volume keys. it again shows the google logo and nothing happens after that.
I have tried many things, but I am not able to resolve my boot loop. Somebody please help me. Please guide me what should be my approach to this problem
Regards
Ishmeet

FOLLOW THESE INSTRUCTIONS ONLY IF ANYTHING BETTER DOESNT COME UP BECAUSE I DON'T WANT TO FEEL GUILTY IF YOU "FUBAR" YOUR PHONE. I am not an expert in this stuff.. I can only follow instructions and the two videos helped me get out of crappy situation in the past couple weeks.
Follow the two videos below on how to re-install your drivers properly and flash and root Nougat 7.0
First go delete your driver from your PC via Device Manager. Anything that you can associate with N6P or Google.
Then watch this video on how to install new drivers.
This video on how to install Nougat
If you can access fastboot, I would just follow Heisenbergs guide (look In the stickies) and reflash the N stock images manually via fastboot. Also, make sure that you flash the recommended TWRP version that he has linked in his guide otherwise you will have problems with recovery. His guide has saved me multiple times when I messed up my phone.

I think I figured out mine problem. I am not sure what you mean by locked bootloader but in my case I was able to reboot to bootloader by pressing all three buttons (Volume up, Volume down and power button) at the same time.
Once you are there and if your bootloader is already unlocked you can flash your own android. Probably this process is called unbrick your phone. I am surprissed and sad as I am not allowed to post link which can help you. Ask admin.
Any related problem while following process. I can try as I am not very expert.
RIP my English.
Thanks

And that's why it's a good idea if you do ANY tinkering to your phone that you have an unlocked bootloader. I have screwed my phone up a hundred times over but nothing that a fastboot flash of the stock Google images couldn't overcome.
I'm not sure what situation you're in but I would try to get that bootloader unlocked asap. Just know that when you unlock it, every partition on the phone will be completely wiped to include internal storage (sd card).
I wasn't tinkering that's the thing. I was on the Android beta but I have installed those OTA. I would love to be able to unlock the bootloader but none of the commands will work to unlock it because usb debugging was not enabled or the developer options and I can't boot it to change that.
I have the Chinese version of axon 7 and under development options I can click on OEM unlock then it asks for a pin number. How do I get that pin number?
Have you contacted zte customer service?
Please let me know how this turns out
I've been around these forums multiple times now and the ways that should work don't seem to work for me :/ Can't find a confirmed unlock of the Chinese version and am stuck on B13 while I wany Cyanogen.
If you go and sign up for ztes website and then go to the developers lounge there is a lot of talk about bootloader unlock. The way I read it you could have signed up to receive a pin number to unlock bootloader but zte has put that on hold? But are suppose to start it back up?
you can flash unlock bootloader in port 9008, I unlocked successfully by this way
@jiabing520a could you explain how?
after booting into recovery my device isnt visible in the device list from adb.

Did you flash twrp ? Official recovery does not support adb.
If you have already flashed twrp, then open computer manager- device manager, you will see your phone doesn‘t work correctly (triangle) , right click on the triangle, and click update driver, then computer will fix this proble automatically.
Can not even get to flashing the TWRP, so stock recovery.
I want to backup the recovery.img in case i brick the device after doing
adb reboot recovery the device cant be found any more in the adb device list so nothing from that.
I tried to sideload it using the adb sideload but the same
it`s saying waiting for device and stays there even when i`m trying to send a file to the device.
Ok little update.
tried to downgrade but getting the error footer not correct and unable to verify.
Normaly saying you can disable this using the TWRP system as i cannot even get the bootloader to unlock.
So i cant get TWRP installed on the device.
If anyone knows how to downgrade the b13 to the b10 so we can use the tools provided in other posts
Please help how further .

waiting for device...you should kill adb process first, and then reconnect your pc

if you want to downgrade the b13 to the b10，maybe you should use official recovery
If you can explain how to downgrade using the original recovery please i have tried sideloading
and placing the rom file in the location reserved for update etc.

Hello Mate,
I am in the same situation as you. I have been looking all over the internet and came across a Chinese forum. Apparently, it is possible to unlock and root B13. However, I have used Google translater to translate the page. It's hard to understand the steps. I have not tested it. But maybe someone out there will have a better understanding and could give it a go. Here is the link

Hi everyone, i cant enter to EDL mode, i need it because my stock rom is unstable(All start with OTA update), after update it show me "unfortunately android.... has stopped " every 3-5 seconds. EDL works fine yesterday and i try to install fastboot rom, but since MiFlash get error when i install fastboot rom i cant reboot in EDL. Hope you can help me.
note: I try reboot trough fastboot and do same thing as the video.
youtube. com/watch?v=gPh1yE3or8g&feature=youtu. be
(Sorry for the video post, but i cant find something like this case in web and i really need help)
You can try load in fastboot, connect to pc and run edl.cmd from archive.
www28.zippyshare.com/v/sKankJGd/file.html
go to fastboot and type "Fastboot oem edl" then enter and you will find the device got into the EDL mode
Unlock your bootloader and flash a custom recovery is the best way
I have the same problem
Hi! I have the same problem! I can´t get to EDL mode, also I cant update with MiFlash anymore.
I´ve been searching for over a week for a solution but I can´t fix the phone.
I´ve done the following.
1. Bought the Redmi 3S phone from Gearbest, came with a rom with adware, I was unable to update the rom from the updater.
2. I downloaded an Official Fastboot ROM from the XIaomi website, then updated to latest version MIUI Official TeamVersion Stable ROM: V8.1.1.0.MALMIDI (MIUI8), without unlocking bootloader.
3. After succesfully updating the phone, Android starts but then I get a continuos error message and I cant do anything. Now I can only get to Fastboot Mode (EDL does not work anymore, even using Fastboot EDL mode). If I try to flash it again with Mi Flash I get Flash tz error.
4. I applied for unlocking, received the message after 48 hours but I am stuck on 50% with the error -current account is different from account info on the device xiaomi-
5. I am unable to update the firmware using fastboot mode, recovery mode or EDL mode, Unable to unlock the bootloader. Already tried several methods with no results.
Please help!
Thank you very much.
If your issue is just to go to EDL mode and get back Qualcomm 9008 port com why not to try the "cable trick" found for the redmi note3.
https://xiaomi.eu/community/threads...-edl-no-fastboot-no-logo-no-led-solved.34113/
See post n°22 and it is no risk to try it. The cable would be reusable.
You have also many other posts on the subject, just goole it.
Here's a really easy way to make a deep flash cable http://forum.xda-developers.com/xiaomi-redmi-3s/help/help-bricked-phone-t3510277/post70029683#post70029683

I got same problem.. But I'am not yet get permision to unlock bootloader.. Please help me.. What can i do to flash my redmi 3s..
Hello,
I have a problem with my Huawei P9 Lite. Build number is: VNS-L31C900B161
Whenever I try to flash twrp using adb I get the message
"writing 'recovery'...
FAILED (remote: Command not allowed)"
My bootloader is unlocked and I just flashed a new firmware. My main goal to to switch to yet another firmware since the one I'm on right now doesn't allow me to open the Play store.
I want to switch to C432 in order to be able to update through the stock recovery (C900 firmwares are nowhere to be found) and I read in another thread that I need to flash oem info using TWRP. If anyone knows another way I'd appreciate some directions.
Oem unlock aswell as USB debugging are enabled.
I'd greatly appreciate any help.
Hello! I have a very similar problem with my P8. Unfortunately so far no one has ever been able to help me. Previously I had 2x Huawei P8 and one P9.I modified all the different methods. I've had some time to learn but this case is beyond my skill.
In my case also the bootloader - unlocked (all known methods for verifying bootloader status show that it is unlocked). Because my phone is connected to a computer running Windows 10 64b tried the methods without the driver signatures (quieter I do not think that is the problem in this because other P8 unlocked on the same computer, the same ADB drivers etc ...) I've tried adb over wifi and even these dubious methods without using a PC. Nothing. The only response: "Command not allowed ". Maybe I will add that dedicated tools type SRK Tools , HWMultitool, WinDroid ToolKit They perform a normal TWRP boot procedure and show that the procedure was successful (!!!) .... and nothing. Black magic. So far in 3 different sites they could not explain it to me.Finally, I will add that this particular P8 is a copy that I got under warranty (previous P8 unfortunately fell but honestly gave me a whole new ... But without any box, Without anything, the phone itself ... Any such blockade made in Huawei?

Hi Guys
I finally manage to unlock my bootloader on my VNS L31 unlocked. I have flashed the TWRP Recovery tool, but I'm stuck on the Booting... text if I press Volume Up and Power. If I do a normal boot, the phone boots as per normal and I can access the OS. After looking around it seems like its because I'm using Android 7.0 - and have tried a few Nougat specific TWRP builds. None of them worked.
Can anyone please point me in the right direction? I'm looking for a TWRP recovery tool that will work, as well as a working root method.
Bonus Question:
What custom ROMs do you guys recommend for the VNS L31?
My experience with the bootloader unlock code that might help some people:
I tried the Huawei request form, but it just gave me errors. I also emailed them twice, but they refused to give me the code. What I ended up doing was using DC Unlocker. It sucked that I had to spend money, but at least it worked... I hope this might save some people from getting super frustrated.
Hi,
It's simpler for you to install directly a custom rom with (include) TWRP recovery and root methode (magisk is cool).
In my personal experience, EliteRom is the best at the moment, the next version was coming soon, please wait (v5) and install.
Advice: reinstall a clean and untouched version of Emui before flashing a custom rom (Elite Rom ).
Follow my guide HERE
EDIT: is not difficult to obtain a OEM code with Huawei website, just try on Chinese version and done!
Good luck!

Flash @OldDroid TWRP from fastboot:
Code:
fastboot flash recovery recoveryname.img
Then reboot to android:
Code:
fastboot reboot
You need to have adb installed on your pc.
I recommend the 15 second ADB installer .
Enable usb debbuging in development settings and give authorization to your pc by confirming the prompt on your phone.
Then using adb reboot to recovery.
Code:
adb reboot recovery
Hope it helps
