Hello,

I just want to share my own experience with you guys, i got my ALE-21 into bootloop after trying to root under Lollipop, after trying every solution here is what i did:

i let the phone stuck in the loop and do "adb reboot-bootloader" it fails of course but i kept redoing it by pressing up key then enter in the windows command shelle i did it like a maniac until it magically managed to succeed int bootloader moder from there i flashed TWRP then an unroot zip and tada saved my phone.

I hope it can help at least to get in that stupid fastboot mode !

---This method only works, if your phone is able to boot---

Note:

Usually no data will be wiped. But to be save do a backup first.

##############A T T E N T I O N##############

DO NOT TRY TO FLASH VIA THIS METHOD, IF YOUR PHONE HAS A CUSTOM FIRMWARE *¹ !

If you try this nevertheless you phone will be bricked!​

#########################################

Information

If your phone has a official ROM/Firmware installed but it is rooted etc. it will work without bricks.

Let's get started

1.0

Download Firmware/ROM (.QSB)

###REQUIRED###
https://www.androidfilehost.com/?w=files&flid=94094

1.0.1

Extract the .7z file with ROM/Firmware you downloaded at 1.0

1.0.2

Connect the phone via USB-C cable to your computer and create a folder called "sdfuse" at the root of your internal storage.

1.0.3

Copy all the exctracted .qsp files into the sdfuse folder.

1.0.4

Shutdown the phone.

1.0.5

Hold down the volume- button and power on the phone. At second vibration release the power button, but still hold the volume- button. Now the developer recovery menue should be shown.

1.0.6

Select "Sd update" and confirm with power button.

1.0.7

Hit "apply" or "OK" with tapping on it. Now the flashing procedure will start immediatly. After this was successful hit the reboot button and you're done.

​

*¹ You flashed a Custom ROM via TWRP means Custom Firmware / Custom ROM. Furthermore if your merchant flashed a ROM with multilanguage support (more than English and Chinese) and it's unable to gain OTA update (non rooted - if you don't know what this is you are not rooted!) your device running on a Custom Firmware!

Zuk Z2 pro bricked

Hello,

thank you for this very detailed description of the process!

I did try it and something went wrong, I do not know where I went off protocol, yet now my phone is unresponsive.

It is fully loaded.

LED is blue, screen black.

Long pressing Vol up plus power -> short vibration and green LED, ZUK logo appears shortly, then screen is black and LED blue again.

When USB is conneted, QFIL 2.0.0.4 does recognize a phone. Chirp on the PC. QUALCOMM HS-USB Diagnostics 900E (COM5) in top line of QFIL

When I try to flash, however, it shows:

"Switch to EDL

Download fail: switch to EDL FailFailed to switch to Emergency Download mode

Finish download."

To me, this seems as a complete brick event.

Could someone of the experts please help me to revive the phone?

Thanks!

Hello everyone, I have a big problem ..

and thik your post m_atze can help me (I have always recover flat mode, perhaps meta mode it is solution ???)

I have a ZUK Z2 2131 (PLUS) purchased on Gearbest ... I have documented very best and then

I installed a stock rom by QFIL

I unlocked the bootloader

I installed TWRP 3.0.2

and then loved MIUI

your phone with this rom miui8 16-12-1 was fantastic, well ...

but as he says: ABOUT TOO WANTS NOTHING TIGHTENING

.... I had everything set up and worked great x who has problems with NOVA you just have to enable management to boot from MIUI app with WIDGET.

Only thing ... I could not handle two SIM and I went to engineering mode via Shortcut Master lite (an app that is on the play store), I changed some parameters ....

After that I started having problems with the phone module,

It found no more sim or rather he saw it when he got a call went in No Sim .... number ...

I did not want to reinstall everything from scratch .. I tried ..

tried again a couple of days, but nothing

eventually via Shortcut Master Lite I gave as I recall command (if someone kindly install Shortcut Master and sends me some screen shot can give more precise information ...

if commands unconfirmed do not make trouble ... HELP ME ... I've installed on my MI4c but does not give me the same connections ....) ...

Given the command CONFIRM the phone is switched off and restarted.

But it went bootloop, I tried reinstalling in TWRP firmware MIUI a two-time, but nothing in the end I tried to reinstall stockrom with QFIL, I managed but the result has not changed .... if not worse, in fact, now I no longer have the TWRP.

All in all still went to boot, but it was and is alive, and I was able to get into fastboot easily

But I read from the post before reinstalling the stock I have to re-lock the BOOTLOADER

fadi and go into fastboot

everything works

fastboot devices

ok

fastboot reboot-bootloader

then give the command

fastboot oem unlock

(I had come to doubt that I should give fastboot -i 0x2b4c oem ​​unlock-go)

however the bootloader was locked

But now .... I could not open QDloader 9008

in the end I did it FOR ALL

just keep premetu VOL + and immediately after POWER putting the USB cable just feel vibrate immediately release the keys

WITH A BIT OF SKILLS succeed YOU TOO

drain well MIFLASH

reinstall the stock, with an option CLEAN ALL (thanks to the TWRP file manager I had made up on a sd with OTG data)

But the end of all the result has not changed my phone is still bootloop

What can I do read the QCN etc but where recuper

Anyone can help me, thanks

I know my phone's a mess but I was able to get up to this part and am at my wits on what to do next.

Oddly enough my phone has the bootloader unlocked, I was able to get twrp installed (3.1.0.1 I think), but every rom I try to flash just fails at various points in TWRP.

I have a rom installed right now (Jaguar) but it's not working for some reason as the wifi does not seem to want to work.

International ROM

Hi, everyone. I just got my Zuk Z2 Pro with international ROM. Is it safe to use QPST/QFIL method to get stock ROM installed? Also, should I start from 1.9 version (like someone suggested somewhere) or I could go straight to latest version? Thanks.
[Lenovo Zuk Z2 Pro Guides, News, & Discussion] kagazushi:
Hi,

I flashed three times my Z2 pro with a stock ROM using QFIL without any issue, so I would say it's pretty safe.

About the version, I first flashed the 2.5, then install custom ROMS, and reflashed it later thinking it would relock my bootloader.

Finally, only the 1.9 relocks the bootloader, so I would recommend to flash this one if you need to relock it, but directly the 2.5 if your bootloader is not unlocked.

I just need to precise that with the 1.9, OTA works perfectly whithout any change, but I couldn't say for the 2.5.*

I hope it would be helpfull for you.
[Lenovo Zuk Z2 Pro Guides, News, & Discussion] mirren_von_bangor:

Hi everyone. I just flashed stock ROM 2.5.335 on my custom ZUK Z2 PRO. Everything went well, I got Download success message and phone went into boot. Now it's stuck at blue ZUK logo. Where do I go from here? I have no idea how to proceed, since I cannot find my phone on my laptop anywhere. This is my only phone. Please help.
[Lenovo Zuk Z2 Pro Guides, News, & Discussion] mirren_von_bangor:
Fixed it

Never mind, I managed to QFIL stock ROM. In case someone else has the same issue, and because this thread seems dead, I will write my experience and hopefully someone will find it helpfull.

First, I tried to QFIL ZUI 2.5.335 and everything looked like I succeeded. I got message "Download success", drivers were showing "Qualcomm USB...", no errors in log. But when my phone restarted, it stuck at blue ZUK logo. This QFIL was done on Windows 10 and phone was fully recognized by system.

After that, I tried it on Windows 7 and using ZUI 1.9 stock ROM. After I installed drivers and started the process, QFIL wasn't showing Qualcomm drivers, but "SHENQi drivers" or something like that. I tried installing qualcomm drivers manually, but with no success. So I decided to give it a try with the QFIL showing "SHENQi drivers". Right after I pressed "Download content", drivers were changed from SHENQi to Qualcomm and everything was OK. Now I have fully functional ZUK Z2 PRO, with working OTA updates. :D

Just got Zuk and want to unlock it, so I have to flash latest firmware, right?

What is difference between QPST and QFIL? A I understand QFIL is part of QPST, but can be installed individually? Is QFIL (standalone) enough to flash stock ot better to use one, which is part of QPST (as seem OP used when he created this guide)?

Should I use some special version to flash latest Nougat (Z2121_CN_OPEN_USER_Q01080.2_N_ZUI_2.5.435_ST_170525_qpst)? Or is 2.7.460 (QPST) / 2.0.05 (QFIL) enough? (latest versions I found)

I'm coming from Xperias where sometimes older version of Flashtool was better. Have some experience with generic MTK devices and Samsungs where flashing tool version was very important for safe flash.

Looks like I have accidentally bricked my Z2 Pro. Please, please... don't say anything as I already feel like an idiot :mad: I was flashing the stock ROM to see what it feels like and during the process I dropped my phone and it got disconnected. I have tried to access the download mode by holding the volume down key and plugging the USB cable but nothing seems to be happening. The phone vibrates once and that's about it - it's not recognized by my PC. Am I doing something wrong? Is there another way to access the download mode? Or is it a proper brick now?

Many thanks.
