Meizu PRO 5 bootloop no recovery locked bootloader - Meizu Pro 5 Questions & Answers

Hi all,
I am in trouble with the PRO 5.
Actual situation:
No recovery mode available
The phone boots but when is time to go in the home screen, the screen becomes black and only the power button response so I only turn it off or restart.
Fastboot mode available but the bootloader is locked
I tried many time with the Multiupgrade tool and TestPCTool but the answer is "Token sign failed"
Could someone help me before to put the phone in the trash

Upppppp!!!!!

You could try to unlock it using "fastboot oem unlock", but if it works it probably wipes the userdata partition, and it may fail. If you manage to unlock it, just reflash the stock image, but without the bootloader.
If this doesn't work, there is a similar thread in a different forum which may help you:

Have you tried flashing the whole system (20150923195421_demo_prd_stable) as described in the M86 firmware upgrade tutorial.pdf ?

It resides in the Meizu Tools post, but never mind that. I dove into the security and fastboot uses secure boot so unless there is an exploit your stuck.
Are you able to flash the boot partition ?
If so, you might be able to flash the recovery.img onto the boot (bootimg) partition. Then drop an update.zip into the root of userdata and reboot.
Good luck.

Hey Grumpy,
I extracted the kernel and ramdisk from the recovery image (flyme_5.6.1.19_daily). Unpack these files into a directory, then run
# fastboot boot kernel ramdisk
If it boots you can:
- erase to factory default
- maybe ?? flash /sdcard/update.zip ??
Good luck :good:

how to recover?

Since I lost everything from the boot to the recovery to the system part to anything, i haven't been able to boot the phone;
I can access erecovery but when I try to recover the phone it stops at downloading and then says couldn't connect to servers so that's dead;
I can access TWRP but when I try to flash MM, it returns errors saying that it couldn't mount partitions (Vendor, cust and other...)
I can access fastboot mode. Some people suggested that I should try recovering using dload but the transfert rate to the sd card is taking forever;
Now I extracted everything from update.app using huawei firmware extractor (see http://imgur.com/MWeCCXi ) what should I flash (via fastboot) and in what order?
I would really appreciate the help.

By Nougat I assume you mean the file that has been digged out somewhere in the web and that is floating around here in the forums?
Well we all don't really know what this build exactly is, which makes it very hard to reconstruct your errors and give you advice... I would never flash that but okay, that's why we are here
Do you have a TWRP backup that you can restore (and if no, maybe somebody can upload you a clean TWRP restore file)?
Have you tried flashing CM / AICP?

Hi there. Earlier I spent a few painful hours in the same boat you were in. I've managed to get back to a fresh install of the Nougat build from this thread, but can't seem the downgrade to MM using the (translated from Spanish) instructions found here (linked from that first thread). How did you manage to get back to MM?
(I should add that I tried to flash boot, system and recovery via fastboot without any success).
Cheers

May god have mercy on your soul.
For the downgrade, I didn't use the b161 directly. I flashed some oeminfo provided in the same folder as the TWRP. Then used b150 ans the three boutons method. Worked like a charm.
Hope it will help you downgrade your phone.
I have the same problem, someone could explain it to me step by step, please

Le Pro 3 URGENT HELP Soft brick?

Hello, I am in dire need of assistance. I'm not sure what I did, but I think i soft bricked my Le Pro 3 LEX727. I was attempting to install a custom rom, I wiped Delvik,system,cache,data then proceeded to flash lineage. When I rebooted it quickled flashed Le Eco bootup then crashed or went to a black screen. Same thing with recovery, quickly flashes "Le Eco Recovery" then goes black. I can boot into Fastboot and the device shows up there, but when I attempt to do "fastboot oem unlock-go" I get "FAILED (remote: oem unlock is not allowed)". Please help me, I really need to fix my phone.
Sincerely,
A grateful person who messed up their phone.
It goes into recovery mode? power button + volume up button. redo the procedure and leaves everything in the options selected .. or I hope you made a backup beforehand, there are various discussions on how to recover
If you can access fastboot, youre golden. Just flash a stock rom

I royally messed up my custom ROM install, this got me to boot again. Thank you.
This should be a sticky, or a part of any installation method. Why? If you upgrade to the latest official firmware (e.g. 21s+), your bootloader will no longer be unlocked with the oem unlock-go method. You *have* to flash this bootloader first so you can then unlock it and do all the other steps.

Totaly bricked Huawei P9 Lite - VNS-L21

Hello!
So I've bricked my phone as said... I will tell you what works and what don't, I need that phone, so please help, I've looked throug whole XDA, but whole XDA and no solution for my phone...
So, when trying to boot into system, not even boot works, it just stays at screen "device is unlocked and it cannot be trusted"
Only my fastboot works and force update(clicking up volume button when booting)
TWRP or stock recovery DOESN'T work, tried probably everything, when trying to boot into recovery, it just stays at screen "device is unlocked and it cannot be trusted"
So basicaly, what I have is: fastboot, force update, which btw, tried to install stock rom by huawei (http://consumer.huawei.com/et-en/support/downloads/detail/index.htm?id=91329) - C185B130 Android 6.0 - But it says: "Software install failed! Incompatibility with current version. Please download the correct update package."
BTW, Huawei P9 Lite VNS-21 Single Sim
I would appreciate any help sooooo much! If it's possible, stock rom, or CM13 work fine to, all I need is just this phone to work, to call, sms, camera... Thats all, thank
Please respond quickly, I need help ASAP, because ofcourse I need that phone quick
Thanks

You have a recovery so I believe that's good news. Try to google your way out of this.
Maybe flash Nougat if the Nougat recovery works.

No relock anything. No risk to hard brick. If you flash down to 711 and then OTA update,it will. No need adb and fastboot install. Install usb and motorola driver
thanks for the quick answer. no relock, so if something go wrong i would still be able to flash some custom and rsolve the issue , right ?

Unlocked OnePlus 6T stuck in bootloader

Hello, my OnePlus 6T is stuck in fastboot mode, I'd like to install Oxygen OS (which I have the zip file on my PC) or install twrp on it in order to flash the OOS but here is the problem:
If I type the command fastboot devices, the phone is detected:
PS C:\Users\Geoffrey\Desktop\OP6T\twrp> fastboot devices
4872f361 fastboot
BUT, if I type fastboot boot twrp.img (with a command prompt in the folder of the file), I get this error:
PS C:\Users\Geoffrey\Desktop\OP6T\twrp> fastboot boot twrp1.img
downloading 'boot.img'...
OKAY [ 0.628s]
booting...
FAILED (remote: Failed to load/authenticate boot image: Load Error)
finished. total time: 0.644s
The phone is unlocked, when I use the OnePlus 6T all in one tool and click Bootloader Status it says Unlocked
Please help me I really Don't know what to do

Well I don't really need to get in to recovery I just thought i could help install the stock rom, what I want to do however is flash oxygen os on the phone, and I don't know how to do it through fastboot
Are you a t-mobile user? You're supposed to use the flash-all-partitions.bat file in order to flash the rom... What exactly have you done up to this point and what files are you using?

No I'm not a T mobile user, where can I get the flash-all-partitions.bat and what do i need to do with it ?
What have I done to get stuck in bootloader:
I unlocked my OP6T with the ALL IN ONE TOOL by mauronofrio
Flashed the TWRP from mauronofrio
But when I wanted to reboot the phone I figured out I was stuck in fastboot mode: if I try to boot in the os it boots in fastboot mode and same thing when I try to boot in the recovery
I don't know what happened..

I'm sorry but I'm completely lost, I have downloaded the ROM but I can not flash it because I Don't have access to TWRP and I can't install it because of the error FAILED (remote: Failed to load/authenticate boot image: Load Error)
So what do I have to do ??
EDIT: I've found this https://forum.xda-developers.com/oneplus-6t/how-to/rom-stock-fastboot-roms-oneplus-6t-t3862516
I'll try to follow this guide, thank you a lot for your help, If this still doesn't work I'll tell you
1. Download the full rom
2. Put your device into fastboot
3. extract the contents of the full rom zip file
4. extract the images and the other flash zip file as well
5. run flash-all.bat, if that doesn't get you to boot, run flash-all-partitions.bat.
Id post your issues in the thread he linked. Specific to your device , most guys here in this thread are on tmo and it's a bit diff for us.

Did you use flash-all or flash-all-partitions?

Hey sorry for the late answer, I used flash-all.bat and waited 5 minutes then my phone rebooted
I can't find flash-all. Is it gone?

I see this worked for you and Id like to try it but im a bit confused about what exactly to do. Could it be possible to have a more detailed explanation of the step by step things you did to fix this? I tried eveything you tried at first and got the exact same error message. I suspect if it worked for you it will work for me but I need a little more direction I guess.

Not recognized by the PC how? Are you trying to use the fastboot command? "fastboot devices" does anything come up?
You will need the fastboot ROM here, most likely to fix this.
Your last resort should be the MSMTool. (Remember it will relock your bootloader)
My Oneplus 6T is stuck on bootloop from 6 hours+ I've tried to hard reset the device, i have tried Volume Up + Power button, Recovery mode, deleting cache, none of it is working.
I had updated using the Oxygen Updater, 10.0 update, and it is now stuck forever in bootloop.
Please help
