Hard Brick Nubia z11 mini HELP

Hello friends
I had a problem with the mini z11, I have a hard brick.
I wonder if there is any recovery rom, or if the official serves me.
I can flash by nubia Toolstudio?
the terminal does not turn black screen on or enters recovery, flash a rom confusion mini z9.
I need help please, if you recognize the terminal QHUSB_BULK is hope.
Thank you for your interest, Greetings

Still a little bit early for Z11 Mini...
Did you unlock bootloader, rooted and installed some recovery?

Bricked device nubia z11 mini
Hi Guys,
I was looking to update the Nubia to v 2.04 from 1.40 so I used flashify to flash the stock recovery (worked earlier) but the system went dead.
I used tool studio to get the recovery back but now it is not reading my internal storage where the files are kept, it suggest mount error with system, data etc .... so what could be a way forward?

Follow this guide to flash twrp, use the vendor id from below guide
https://forum.xda-developers.com/android/development/recovery-unofficial-twrp-3-0-2-zte-t3550995
Then u flash the rom.
Before flashing the rom, wipe everything expect internal storage and sd card

Need persist.img
Hi,
Have got to know persist.img is corrupt. Hence, flashing is happening but no booting even twrp is not helping. Persist.img is usually found in fastboot img of the rom which helps to install rom in fastboot mode. Kindly do let me know if I can find fastboot.img of Nubia z11 mini.
Thank you

Hello guys,
i have the same brick mode as the op.
The system doesn't recognize the mobile, it only shows it as QHUSB_BULK and it keeps disconnecting.
What are the steps to follow from the pc?
I found somewhere one software called one click unbrick but when i try to install the drivers with it it says that "the system policy has been modified to reject unsigned drivers".
If i can take it to the place where the phone is recognized as a storage from the pc then i can take it from there.
Thanks

Unbrick and downgrade
I once brick my nubia the same way. BUT NOW ITS ALIVE AND WORKS FINE (sulking why didn't I bought the ZUK 2 even though at the time i bought z11mini they were similarly priced)
UNBRICKING:-
ALL you have to do is download the same firmware which was installed prior to the rom to which you downgraded to [ simply put if you had v2.40 running before and tried to install v1.40 then download the v2.40 rom for flashing), once downloaded {USE A PC OR MAC TO DOWNLOAD THE ROM OR ELSE IT MIGHT GET CORRUPT} copy it to the root of an sd card(2gb upto 32gb; sdxc cards may not work), insert the sd card into the phone , then press and hold the power button until the phone reboots, as soon as you see the bootlogo press and hold vol- and power keys simultaneously, you wold boot into nubia recovery now select update from sd card confirm and let it install as soon as update finishes your phone will boot back up normally. [UP TILL THIS POINT NO FILES WOULD BE LOST].
NOW YOUR PHONE WILL BE WORKING AGAIN.
DOWNGRADING:-
YOU DON'T NEED ANY EXTERNAL SOFTWARE FOR THIS
JUST DOWNLOAD THE ROM U WANT TO INSTALL AND PLACE INTO SD CARD AS ABOVE.
TAKE A BACKUP AND SAVE ON A PC, ANOTHER PHONE OR ANOTHER SD CARD{not the same one} OR ANYWHERE ELSE SAFE cause after this everything inside your phone will be DELETED.
BOOT INTO RECOVERY as STATED ABOVE.
-ATTENTION- DON'T install the rom as yet.
FIRST WIPE cache and data.
SECOND- INSTALL THE ROM SIMILARLY AS PRESCRIBED ABOVE.
THE SYSTEM WILL INSTALL AND REBOOT.
ENJOY{but why are you so eager to downgrade your system, i was once as well but after downgrade to lollipop.....nothing......performance was same as on Marshmallow.
ADVICE- for some reason the ota updater never shows any new updates, you will have to download updated roms from nubia website to install using recovery{the app has option to apply local update but it does nothing and gets stuck on nubia logo, u will have to restart your phone after that}, as long as you are installing updates u don't need to wipe data and cache and also your files will remain intact. BUT TO THIS ONLY EXCEPTION IS V2.06, on this you do not need to wipe data and cache but the rom itself will wipe all data on your phone so be careful. :good:

Redmi 1S stuck at mi logo : How to recover data?

Hi everyone,
My Redmi 1S bailed out on me and is now stuck at the boot logo. I need to recover my data, before I flash a rom onto it.
Can someone please share a way by which I can access and recover my data from the boot screen / recovery mode / fastboot screen.?
Quick update : I tried Mi Flash but my phone is not getting detected
Please help
Thanks a ton in advance.

If you have a custom recovery like TWRP, you boot to recovery and use the built in file explorer or ADB to pull files out to the memory card or otg pendrive. If you don't have TWRP installed, then boot to fastboot and install TWRP first.

[HELP] im stuck with no os and mtp wont work in twrp and also ADB isnt working

i flashed miui 9.3.28 and then booted twrp , but it was asking for password so i went to wipe and repaired data using ext4 ,and then procceded to wipe data, vendor, cache, system and now im stck with no os and i cant use adb sideload to install a rom please help :crying: :crying: :crying: :crying: :crying: :crying: :crying:

Reboot into fastboot(keep pressed power and vol - buttons until you plug cable to pc otherwise it can start rebooting system) and flash latest fastboot miui(you need to unzip it first): http://en.miui.com/a-234.html via XiaoMiFlash tool with clean all option. If you can't see your device in tool press refresh in MiFlash tool you have also Driver section check this. Another option is to install google latest_usb_driver via device menager(right click on your device->update-driver->browse pc -> and select usb driver.

I got the exact same problem after flashing the same beta build. Nothing worked for me so I had to flash the fastboot image and roll back the stable channel.

Op next time don't wipe vendor partition.In your case you should get recovery with supports MIUI on androind 9 and if ou had encrypted data you should format the data. Here you have similar situation: https://forum.xda-developers.com/redmi-note-5-pro/how-to/recovery-pie-update-miui10-t3916963 (I didn't try this one)

Remember For decryption it only needs to format data partition only.
How will it boot if you wiped system as well as vendor partition.
If you can get in recovery just flash the update file 9.3.28 and u r ready to go.

I did all that and formatted the data partition which was decrypted afterwards. The problem is that internal storage gets re-encrypted after I boot to system.

Can you give the version of twrp which worked in Pie.

Regarding your problems
Copy any rom to a micro sd card and flash it through twrp if done ur done

Try using OrangeFox Recovery, I had the same issue ADB & MTP connection with TWRP for Whyred.

Thanks. My main problem was that mtp driver of Miui was wrong. And the decrypt error was solved by Redwolf recovery. i have yet to try OrangeFox one.

Question After installing A12 based rom fastboot isn't working properly

Hello to everyone, I hope that someone could help me. Today I installed a ROM based on A12 Pixel Extended to be more precise, but I don't really like the ROM and wanted to go back to miui.eu or evolution X (A11) I was going to flash the stock rom via the miflash tool but as soon as I it flash the device disappear from the list of the devices connected and when checking with CMD for "fastboot devices" nothing shows up. Does anyone knows a way to go back to the stock firmware to be able to flash the miui.eu? Thanks in advance to all.
PS: I can use the phone with the pixel extended rom. But fastboot isn't working and recovery (twrp) does not show storage to flash anything

You will need to get a USB c drive and load a rom and files to that when you do wait a few seconds and hit select storage it'll show 0mp on otg you click the 0 and it loads it up.
Also you can try to go into twrp right now and go into backup and hit refresh sizes on your internal storage and it should show sizes and read internal storage.
If you can flash an android 11 rom I would I would choose EU stable and flash in twrp and do a full format data once it flashes. Let me know

Thank you for your reply.
I manage to solve the issue somehow but changing the drivers on the device manager on the windows was enough to solve the problem completely so I hope that anyone facing the same issue can see this. I will now proceed to install an A11 ROM! Once again thank you and have a nice week
