Hi there !
I just switched from a Windows Phone to a Huawei P9 Lite (VNS-L31), my first Android phone (never too late, I guess?).
I was following the instructions provided in this toolkit (https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873) to unlock the dual SIM support, as this phone is from Orange and locked to single SIM.
I successfully unlocked the bootloader, installed TWRP and rooted the phone. I got to the stage when updating the phone from the SD card is requested. Stock firmware was L31C109B120, new firmware is L31C432B130.
The update seemed to progress well, but actually no, as the phone is now bricked (black screen, screen will not power on, does not display anything).
Powering the phone with any combination of Vol+, Vol- and Power depressed results in nothing at all.
So I installed adb + fastboot and at least the phone is recognized in fastboot. I successfully unlocked the bootloader (again?) within fastboot with my unlock code.
Now I am able to manually flash the boot, recovery and system partitions from the B130 firmware. Unfortunately, this results in nothing, the phone will still not boot to anything else than fastboot mode.
I have limited knowledge/experience with Android phones, so I am kind of stuck now. I have read several topics and fastboot definitely seems to be the way to go, but there must be something that I am doing wrong.
I was wondering whether someone would be willing to give me some insight, please?
Any help would be highly appreciated!
Many thanks in advance,
Regards,
Eric.
[Edit]: I was able to flash the stock VNS-L31C432B130 firmware but not with fastboot... I had to use DC-Phoenix and pay 15€ to do so. Is there a free equivalent to DC-Phoenix yet?
Hello
I think you should disconnect the cable and press on volume + and power erevovery wipe factory, cache. Restart
If it does not work, start again.
With the toolkit, bootloader code, installs twrp,
Go download c432oeminfo double sim.zip Badwolf
Fashe c432oeminfo.zip.
switch off.
Doad b130.
Yes, this solution saved my phone... And u can try flash with fastboot any partition (recovery, system....)

Thank you for your help, guys!
Yet, nothing happens when I disconnect the cable and try to reboot the phone while holding Vol+ and Power. Vol- and power or Vol+, Vol- and Power do not deal any better result unfortunately. The screen remains off.
I believe I should delete/flash something through fastboot, but I do not know what! I believe I have tried everything I could think of, and I am running out of ideas...
Yet the phone is accessible through fastboot, so all hope is not lost, right?
Well, I have good news: I managed to reflash my phone by following this thread: https://forum.xda-developers.com/hua...green-t3485836
You have to download and use DC-Phoenix to flash a stock firmware to the phone.
The bad part is that it is a paid service that will cost you 15€... but for me it was worth it in comparison with having a dead phone.
I wonder why no one has come up with a free equivalent to DC-Phoenix yet?
Hello. Guys i have a big problem that i need so solve fast. I just tryed to unlock the bootloader with SRKtool for huawei with the code from huawei site, but after it finished the device needed to restart, but it didn't! Now it's stuck on the unlock bootloader screen and i can't restart it. I'll try opening it and removing the battery and putting it back on. Would that restart device to normal?

Hi All.
I hope someone can help me. I encountered this stupid problem:
I have a L31 device and successfully installed the Nougat (test?)update through Firmware Finder. But since this wasn't the definitive update, I decided to rollback to MM. I installed the C900B300 rollback package and then the B160 package. That went well, BUT the device now refused to activate the Google services. I couldn't enter a Google account. Not from Settings > Accounts and not from any other Google app like Chrome, Play Store, Gmail or others. The screen just kept returning to the Homescreen.
Upon checking About this device, I noticed the version now was C900B160, instead of the expected C432B160. I am very positive I used the C432B160 MM package to flash. This I did with the three button method. But then how come it still showed C900B160?
So I first tried to reflash the C432B160 with the three button method. Flashing worked well, but the problem wasn't solved. Still no Google activation and still the same C900B160 number.
So then I decided to reflash the rollback package...
That turned out to be a mistake... After flashing that (and it did show 100% successfull after flashing) the device is bricked. The Huawei logo shows and then nothing happens. The logo stays in the screen. I can't even turn the device off. Short pressing the ON-OFF button does nothing and long pressing just restarts the logo and nothing more.
I tried to reflash the MM update C432B160 with the three button technique, but that doesn't work anymore!! Entering erecovery with the volume up and ON-OFF also doesn't work anymore!! The only thing that works is Fastboot when connected to a pc. That screen shows phone (and bootloader) is locked, by the way. So I can't flash boot.img and recovery.img .
Has anybody encountered such problems and knows what to do now?? Thanks guys!

With fastboot method, unlock bootloader again. Flash recovery. Boot into recovery. Wipe system and boot. Flash stock boot IMG and recovery IMG. Power off. Use dload. Now you are in bootloop. When booting press vol up 3 seconds, on e-recovery press shutdown. Press and hold power and vol up. Go to stock recovery, do factory reset.

Thanks for your help.
Trouble is that I can't unlock te bootloader, because I do not know my Product ID and I can't look it up, since I don't have a dialer... The HuaweiProductIDGenerator doesn't help. I tried several codes with it, but none worked.

No, I can only get into fastboot when connected to a pc.
OK. gtdaniel was so kind to provide me with an unlock code. THANKS!
But, I don't seem te be able to use it...
I can put the phone in bootloader when connected to a pc. When I type "fastboot devices" I do get the correct serial number. But when I type "fastboot oem unlock 343...338" I get a FAILED (remote: command not allowed).
It seems this is because I never could allow OEM unlocking from the Android settings menu. But since my phone is bricked, I can not enter into that menu!
Does anybody know how to solve this??

at command line when u write adb devices u got your phone ?
Maybe is dump question but did you install adb android driver ?
I'm pretty sure that someone wrote in thread that you don't need to have this oem permission in android if you are in fastboot

OEM permission need for fastboot/unlock bootloader.

Yes, that's what I read too. Since I can't change that permission anymore while I can't start Android, I can't unlock. Dammit.
Is DC Unlocker my only option then? It seems their software can do it.
I'm afraid I've got some pretty bad news. Last week the same thing happened to me after I was THAT stupid to actually try and flash the rollback package for the second time. My phone got bricked just like yours, and NOTHING worked to fix it. I tried completely everything I could find on the net and XDA, and in the very end I was forced to bring it in for warranty repairs. Even they COULD NOT fix it and the phone ended up with the entire logicboard changed with a completely new one. I was lucky that it all was done under warranty. Will never do anything as stupid as that!
Really hope you find a fix somehow, but if not, the repair service is your only solution, because otherwise the phone is as good as dead.

my phone is also reedy to send to service. I have a lot of phone with android but no rom make so many damage to my phone, like this fc** rollback. finger cross, because huawei service in my country without warranty,takes for new motherboard 175 $ . I bought phone for 233 $ with 3 gb ram..... This will be harsh and pay(in)ful lesson for me.

Uhh, I am sorry to hear that. But yes, I had the same harsh lesson. They will be forced to changed the motherboard too, cause even they won't be able to re-flash the whole system. Though, what I did to have the warranty not declined, is I brought the phone to the service and said that - "The phone received and OTA update through the updater, I didn't look much into it and just went with it, pressed on update and everything seemed well. It worked until the moment where it installed and restarted, and now the phone is stuck on Huawei logo and you can't possibly do anything with it, not even turn it off." - and that's it. They will have to repair it under warranty because there is no proof left that you had rooted it or done any other installations not authorized by Huawei.
Best of luck!

I know that i read somewhere how to manage to this oem lock. I was 50 % right.
https://forum.dc-unlocker.com/forum...61751-huawei-mate-9-mha-l29-erase-frp-problem
Some user got the same problem that you have and flash boot.
But truly if u don't have "your device has been unlock" only bootloop on huawei logo, is more simple to send it back to warranty and play dump.
I have now "your device is unlock" and i pray for miracle.

I am exactly in the same situation with the difference that I don't have Fasboot! How do you get to Fastboot? Mine hangs on the screen that says the phone is unlocked and the device is booting... Vol+/Vol- and Power doesn't boot into Fastboot and my minimal ADB doesn't recognize the phone in the stages that it hangs...
---------- Post added 16th April 2017 at 12:04 AM ---------- Previous post was 15th April 2017 at 11:52 PM ----------
I have the same situation. I tried everything, Three button method, letting the battery run out completely, Vol+ and Power, Vol- and Power, connected to PC, not connected to PC. Every time I disconnect the charger, and reconnect it starts from 0. I read some other people here have the same problem. Send it to warranty and explain your rollback process unlocked the bootloader somehow (I mean the phone does do a lot of sh*ty sh*t, so this shouldn't seem very odd as well!!!) and hope that you get a repair/replacement and after that sell it on ebay hoping some stupid people like us in the first place will buy it and spend your money on a phone more reliable!
I managed to access the fastboot using the 3 button method in cold boot. Hold the Power key until the screen goes off and then release and hold down the Vol- key and immideately connect the usb cable to PC right before it vibrates or exactly when it vibrates (it's a matter of timing), and bingo you are in fastboot and you can flash system.img, recovery.img, cust.img, cache.img and boot.img from there, but this is not how I revived my phone. I used the 3 button method again when the phone was charged for like half an hour or so and the did the same cold boot trick and I could boot into the force upgrade environment (strangely this still didn't work whitout connecting the usb cable to PC), but it somehow didn't want to read the UPDATE.APP that I had in dload folder on my SD card and wanted to have it from my PC (I just felt it nad there was no indication of it ) so then I installed the DC Phoenix tool and payed 15 euros to be able to inject the complete UPDATE.APP to my bricked phone and the installation went well to 99% and failed, but I rebooted the phone and I could boot normally. Just to make sure I did a factory reset afterwards. Hope this helps.
Cannot get into Bootloader
Hey there!
Essentially as stupid as I am i flashed the Rollback Image at Android 6.0 too, because i wanted to get rid of C900. So now my phone is stuck in the Startup screen too. As mentioned here, I wanted to unlock bootloader again; The Button combination does not work, and if I want to start in bootloader via ADB, it just says "waiting for device"
i am really desperate and i don't know what i should do now
Thanks for the help
EDIT: Somehow managed to got it into Bootloader. At the moment i am unlocking it. Where do i get TWRP and the needed things? Please help, i'm just some noob who doesn't know how it's done
EDIT2: Solved, got Stock Recovery Re-installed, Flashed with the Force Update Method the Main Package of the Rollback (so not the temp rollback data), and worked. But Still C900 and no Google sign-in possible. Someone know how to solve?
Hi, I bought a second hand zte axon 7 a2017. I want told it was rooted or anything. Power button is squashed in so got it for cheap so bought it. Phone runs fine on stock rom and for restarting etc I use mi pop and power button can still be used by poking it hard at an angle with stick etc. I'm familiar with rooting, flashing etc but it is the first time I'm using zte so it's bit different.
Issue is I want to root it to get rid of bloatware etc. I downloaded Root Check app and it says it is rooted and busybox is installed but there is no super user app. Funny thing is I have no means to check if bootloader is unlocked and can't even boot to bootloader mode as it just gets stuck at zte logo when I try to boot to bootloader mode from recovery mode. I get to recovery mode by restarting the phone from mi-pop and holding the volume up button. I don't even think there is custom recovery installed too which I don't know how that's possible as my understanding was custom recovery needs to be installed earlier in order to root.
Can someone please throw some light and give me some guidance. I want to go full stock but rooted and want custom recovery too just so that i can make a nandroid back up.
I'm on Mi favor 4.0
ZTE_A2017V1.0.0.B07.0
Thank you in advance
I'm on the US variant so I'm not too familiar with yours. I would suggest starting from stock, and downloading MiFlash, and the latest MiFlash edl package for your variant.

Okay, couple o' things:
- If your bootloader is unlocked, there should be a screen when your turn on the phone that says 'Your phone can't be checked for corruption. Please lock the bootloader' which is there for around 10 secs. If you use the volume buttons from there you should be able to select recovery or bootloader
-It is possible that you don't even have a working bootloader mode. IN CASE THAT YOU DON'T HAVE THE SCREEN I PREVIOUSLY TALKED ABOUT, try with adb: install adb, enable usb debugging, authenticate in the phone, "adb reboot bootloader". If it reboots into the bootloader (Should say START in green plus some text) then you can unlock the bootloader. But follow a guide before attempting that, or you'll risk a brick
-Having the stock recovery doesn't necessarily mean that the phone is not rooted. If you have the stock recovery it could be because the previous owner simply rooted it, used it, then flashed the stock recovery and sold the phone like that. Which is really weird in itself
-What you should do to recover from this mess is use MiFlash. Find a package called "A2017_NOUGAT_FULL_EDL" (might have a version number somewhere, just use the most recent). Enable OEM unlocking and USB debugging, then issue "adb reboot edl". The phone seems off but it's not. Now unpack the file and install it to the phone with MiFlash.
After you reflash the system you can proceed with a guide. If you get the warning screen when you turn on the phone then your bootloader is already unlocked and you can proceed with installing TWRP (maybe via axon7tool) then flashing Magisk.
