Help me please :( LineageOS bricked my phone :(

Hello guys
I have a problem
Description:
I have ZUK Z2 and its great phone. I installed latest LineageOS ROM which have OTA updates and yesterday prompt a comunicate that I can update my phone so i clicked to upgrade. But then system is not launching and there is only twrp mode so it's bricked i tried to restore my phone with method described here but it did't work :/ QFIL says" Download Fail: Sahara Fail: QSahara Server Fail: Name of directory is invaid (last one I translated because it was written in my native language). I checked FAQ and i restarted my computer and phone, i changed name of directory to ZUK and it still doesn't work :/ Then I found that ulocked bootloader may be a problem so I tried to lock it but it doesn't work either :/ i wrote adb reboot bootloader and my phone runs fastboot mode but command "fastboot oem lock" don't work, it says only "waiting for device" and nothing happenes :/
Could you help me to unbrick my phone? i'm very desperate

Since you can enter the recovery mode go to mainscreen of twrp, wipe system, data, dalvik etc (but do not wipe internal storage!!!) and then install again lineage, google apps, and addon superuser (in case you want root)...
Regarding QFIL method. I have flashed twice the ZUK orginal software with unlocked bootlader and the bootlader remains unlocked also after the flash. I guess you cannot flash with QFIL and you get the Sahara notice because it is either:
+ you have installed the wrong ZUK drivers or
+ the rom folder name is too long or it is something else.
QFIL method will wipe your entire phone though. So i would try first to wipe with twrp and if it does not work then try QFIL.

I tried to flash ROMs via twrp like you wrote but still only TWRP starts and nothing else happens :/

Hi, what if I cannot get the the phone connected to CFIL? It always starts into twrp as soon as the phone is connected to the PC and it doesnt matter what buttons I keeped pressed.....

You wrote it wrong, when you try fastboot you need to use "fastboot -i 0x2b4c" otherwise it judt wont work and will always showing "waiting for device" hope you can get futher now.

Sorry, I dont got your point...

Hi
Head for zukfans.eu
Theres a thread and plenty of guides

Yes, there are guides but no one works for me so I came here for help :/ i'm desperate and i don't know what to do now :/

Are you able to boot into twrp? If yes, then wipe system, data, cache and flash rom again. If not, then boot into fastboot mode by holding down both volume button and connect your phone to PC. Once you're in the fastboot mode you have to flash recovery using the
Code:
fastboot -i 0x2b4c flash recovery <recoveryname.img>
, after flashing boot into recovery and allow for system modifications if a dialogue pops up and flash any custom rom with latest gapps (but you still need to wipe system and data) .

This worked for me on the advice of one of the users at zukfans:
Go to TWRP recovery terminal commands, and enter the following:
dd if=/dev/zero of=/dev/block/platform/soc/7464900.sdhci/by-name/misc

Don't do this if you don't want to have your phone baseband completely removed meaning no sim card function at all. I did exactly this when trying to install stock room and it deleted my baseband. Luckily I had made a backup a month before that. I restored it from the backup and the phone (sim card) started working again.
Anyways, back to the original issue. So you're saying your phone isn't recognized in fastboot? When I wipe system and data and then go into fastboot and enter "fastboot devices" it shows nothing but I can still flash files into the phone. I'm guessing this is because the phone has no 'name' due to the system wiping. So try going into fastboot on your phone, connect it to PC and open adb, and then enter the command 'fastboot flash recovery twrp.img' (download the latest version of TWRP for Lenovo P2 and rename it to twrp).
If then you are able to enter TWRP after rebooting, download stock Lenovo P2 ROM and flash it.

Wiped everything using TWRP and need help restoring.

Hi.
So I was messing around with the twrp custom recovery and (without thinking much of it) wiped everything in the advanced wipe menu :crying: (System, data, EVERYTHING)
I knew I had removed my OS and that I could just use the twrp recovery to install a new rom onto my phone BUT little did I know, when I tried to boot into the custom recovery, it would just loop the screen with the redmi logo
I am still able to boot into fastboot mode, and I have tried to flash the same twrp recovery but with no avail (It still loops the redmi logo screen)
So now I'm here to ask if there is any advice that you could give me to try and fix this problem that I have gotten myself in (I am not worried about deleting any of my personal files. I would just like to get twrp to boot so that I can install another rom)
Thanks in advance to anyone who can help me with this problem :highfive:

Hi, which rom are you trying to install? for android 9 use this recovery https://forum.xda-developers.com/re...overy-unofficial-twrp-recovery-redmi-t4002397, for android 10 this one... https://forum.xda-developers.com/showpost.php?p=82062075&postcount=7...

If what nuvulet said doesn't work, in fastboot, flash the exact same stock ROM you had before, let it boot and then flash TWRP.

Hi, thanks for the fast reply.
The stock android I had before I wiped everything was android 9, MIUI 11. I tried againt to flash the recovery through fast boot but (like before) when I try to boot into the recovery (by holding the volume up button as it reboots), the redmi logo keeps appearing and disappearing and doesn't go to the twrp recovery. At the current moment I don't have any OS installed (since it got deleted when I wiped everything)
Any other leads I could try?

I'm not sure how I can flash the stock ROM without the twrp recovery. I had the impression that you needed twrp recovery in order to install ROMs in the first place.
If there is a method to flash a ROM using fastboot, please explain since my unexperienced self has no idea how to do this. :laugh:
Thanks for the fast reply too

MiFlash works through fastboot mode. It's also safer to flash with MiFlash, just make sure you have the correct ROM.

Yes, this is the method I used to flash the twrp recovery.
My problem was that even after installing it (using this method), i would still not be able to boot into the recovery.
However, it is fixed now. I used the Mi Flash tool in order to install the stock rom and then installed twrp after that. :good:

I tried this method and IT WORKED!!
After installing Mi flash I was able to download the stock rom and install it through the program without any errors.
I was then able to finally boot into the OS and install twrp recovery, then install the custom rom! :laugh:
Thanks for this method. I would probably still be stuck on the Redmi logo if it weren't for this

Problem with Fastboot reboot and Can't install new firmware

Hello guys, i have a mi 10t pro, today try after unlock devices 7 days to flashed and downgrade because my battery drain is significative, i had 12.5.1 eea firmware and try to downgrade to 12.0.19, but now phone is in continus reboot in to fastboot, i try to flash with last miflash tool, but after 2sec is tell me that firmware upgrade is complete and now i can't start my smartphone. i can try to flash last rom fastboot 12.5.1 but without result. How i can resolve this problem? thanks in advance

When trying to do any major change like a downgrade, you must factory reset. MiFlash should have done that for you, but I guess there's a chance it didn't.
To do a factory reset from Fastboot you can use a compatible version of TWRP and just boot into it (not installing it).
Eg. fastboot boot TWRP_apollo_3.5.0_10-beta_1_whyle.img
From within TWRP you can then do a factory reset and see if it'll boot.
If it still boots into fastboot then you have the option of an alternative ROM. Xiaomi.eu provides a debloated version of the Chinese MIUI ROM. I'm running its latest 12.6 version and it has no problems with battery drain. https://xiaomi.eu/community/threads/21-6-23.61942/

Thanks i can try any solution. i install trought cmd fastboot comand twrp image file and after try to reset it? help me if you have other solution to I was hoping there was a way to bring it back to a stock firmware or a recovery firmware. I tried to flash all.bat inside firmware 12.5.1 my last firmware, proceeded it's fine and complete but after install my phone reboot continuos after logo. as if it didn't have a firmware installed.
P.s. Explain to me the procedure to start twrp without installing it step by step. Thanks so much ^^

To use TWRP to factory reset, first find a compatible TWRP. I used the latest version from:
https://forum.xda-developers.com/t/...r-mi-10t-mi-10t-pro-redmi-k30s-ultra.4187427/
which was TWRP_apollo_3.5.0_10-beta_1_whyle.img
Boot into download mode
Then type this exactly (or change to a different file name if you're using a different version of TWRP):
fastboot boot TWRP_apollo_3.5.0_10-beta_1_whyle.img
Once TWRP starts up, go into Advanced, Wipe.
Tick
- data
- cache
- dalvik (dalvik cache)
and select to wipe it.
Reboot system.
That should leave you with no account set up and enable you to boot and setup from scratch in most cases.

update Mi-flash. There's 2021 version.
Code:
fastboot reboot bootloader
disconnect USB cable and reconnect it again
flash again with Mi-flash, do not lock it.
Fastboot ROMs are more than 3GB.

hELLO PL1992, i have use now MiFlash20210226 version installed for 1sec and nothing is installed, the mobile is in fastboot but I can't figure out how to complete the flash of the fastboot rom. I am using the latest EEA fastboot rom for my device, I have tried several versions even earlier but nothing. he says he has completed the procedure but in 1 sec he does absolutely nothing. Do you have solution ideas to try? alternatives to miflash? I also tried to install by extracting the Fastboot rom from inside the rom with flash all.bat, the procedure always go well, but the phone keeps restarting after the MIUI logo every 2sec. I have windows 10 pro i don't know if it is the problem

Did you execute the code given to you before you flash it?
In Mi-flash, click Driver, then install.
After it's done, reboot your PC.
Then do the
Code:
fastboot reboot bootloader
command.
The flashing process should be more than 500 seconds if it's done correctly.
The fastboot ROM should be extracted, not using directly the tgz file.
Rename the extracted folder name short, like "1", and put in C:/ drive.

It seems the ROM and your device is not matching, so it don't flash.
First confirm what your phone model is. The model should be written on the box came with the phone.
Install this program:
XiaomiADBFastbootTools (Java)
https://github.com/Szaki/XiaomiADBFastbootTools
It will need java SE, follow the FAQ guide in that github to use the program.
It should show you what phone you have.

Recovering data on a DEAD Redmi Note 8 PRO

Hello,
I hope this is the right section for this post.
I've been using a Note 8 Pro with zero issues until one week ago when I accidentally dropped the phone in the water.
After a few seconds submerged the display turned off and I felt an intense heat coming from the zone of the battery.
Having no chance to recover the phone (tried with Isopropyl Alcohol too) I decided to open it and manually dry/clean each component, having seen the situation inside gave me the phone is dead but I still want to recover some pictures/data from it.
Before opening the open Minitool was not detecting any device on my Windows Laptop, after cleaning each component Minitool is instead detecting the phone via USB, but I still can't extract any data because the "Usb debugging" option is not tuned on (and no the device is not rooted).
Is there any option to extract data from the phone? There's a way to turn on USB Debugging via ADB on a non-rooted phone?
Thanks,
Andrea.

how about trying your luck with a service ? most of the time they do have access to special programs, which have a better functionality than adb.

Thanks for the hint, but I am not happy with the idea of someone playing with my data

1. Try reboot phone to recovery
2. Connect it to your computer (download Platform-tools)
3. In the folder with Platform-tools open cmd
4. In cmd - adb shell
5. cd storage/emulated/0
6. ls
7. Now, using the commands, drag files from your phone to your PC

Thanks for your hint.
No luck so far, I think because the phone is not in recovery mode.
I can hear the phone starting up several times (hear the jingle) so I think it's in a reboot loop and I don't know how to boot it into recovery mode wo a working display (tried with power/volume up combination with no luck).
From the windows taskbar I can see that the phone is recognized for a few seconds before it restarts.
EDIT: trying to switch the phone on with the combination "power/volume down" brings to a kind of stable state and I can now see the phone in the windows taskbar recognized as a generic "android device". Still no luck when trying to access the phone as there's no device in windows and no device obtained through "adb devices" command.
EDIT1: I think that the phone is in "FASTBOOT" mode. If I type "fastboot devices" I can see it detected but still can't access it.

Any idea? Should I give up?

If it's popping up and down you need something to keep track.
You can try my UsbLog.exe (in the sig), it just sits there and shows what devices appear (if they have a driver) and disappear.
Try these to see if anything is working:
Code:
C:\>fastboot devices
C:\>fastboot getvar all
C:\>fastboot oem device-info

Yes it's popping up and down when it's booted in recovery mode whilst is stably connected when in fastboot mode but in this case I can't access the internal memory of the device.
I didn't get the purpose of logging the devices connecting to the USB as I can see the device connected for a while and correctly recognized as Redmi Note 8 pro but as it keeps popping out windows have no time to show it's folder.
As for the code you wrote: i will try asap but already tried with "fastboot devices" and I get the phone correctly listed but still can't access its memory as told.

After rebooting the phone in fastboot mode I can see it recognized as a generic android device from windows (still can't access the storage folder of the device).
fastboot devices----> I get the device listed with a series of numbers/letters
fastboot getvar all---> I get a list of information on token/token version/partition type and size/baseband/bootloader etc.
fastboot oem device-info----> FAILED (remote: unknown command)
So I think it's clear that the device is in Fastboot mode and instead is in a boot loop when started in revocery mode.
Is there a way to extract data from fastboot mode?
Thanks,
Andrea.

If you put a custom recovery on it in the first place you can try reflashing recovery from fastboot.
Fastboot doesn't allow you to read anything.
oem device-info is obviously an oem command that might not be on any device.
You've got a Mediatek processor. That has some low level equivalent to Qualcomm EDL, but I have no experience with that.
If you can get there you can download the user data partition, but it's probably encrypted. Also no experience with that.
The easiest is if you can get the system to mount/decrypt the partition.
You've tried the normal system too?
Is this A/B? Have you tried changing slots?
How much time does it stay up in recovery? Do you have ADB? Maybe try:
Code:
# stop recovery
Does that prevent it from looping?

So I should try to flash a custom recovery like TWRP for example?
What you mean with "normal system too"?
Changing slots you mean changing usb port?
It stays in recovery less than one second so I can't give any command via ADB.
EDIT: cant' flash any custom recovery because the bootloader is locked.
If I Try to unlock the bootloader via MiUnlock I get a warning saying that all data will be erased.
Any idea on how to unlock the bootloader wo wiping all the data?

My bootloader is unlocked!
Thank you very much.
Now I am going to try to flash a custom recovery mode via fastboot in order to access the internal memory of the phone.
EDIT: I've just flashed twrp-3.6.2_9-0-begonia.img but still can't boot into recovery mode.
Any hint on how to extract data from the system now?

You really want to boot the normal system because that's the best way to get decrypted data.
I realized that you don't have ADB enabled there.
You should look at B. Kerler's https://github.com/bkerler/mtkclient/
If you can pull the boot image off your device then I might be able to fix it so that you have ADB.
You'd have to flash it back in fastboot or mtkclient.
You can also pull a copy of userdata off the device with mtkclient.
As far as booting into recovery, there's a way.
Here's how, if you don't have A/B (that is you flashed TWRP into recovery and not recovery_a or recovery_b)
then you can fastboot flash a special file into the misc partition and it wil boot into recovery next reboot.
To return things to normal you have to flash the empty file to the misc partition.
Code:
C:\>fastboot flash misc misc-rec.img
C:\>fastboot reboot
Only do this if you don't have partitions that end in _a or _b

I really don't know if I have partitions A and B as you mentioned and I think there's no way to check actually.
I confirm I don't have "USB Debugging" active on the phone.
So if I understand correctly I should do the following:
- Flash misc-reg.img via Fastboot
- Boot into recovery just rebooting the system after flashing the above file;
- use MTKclient to dump userdata or boot image to enable ADB on (I will need help with mtkclient I suppose).
Is it correct?
EDIT: flashed TWRP first and misc-rec then rebooted via Fastboot/Reboot but nothing happens.

TWRP cant boot because you used wrong one. Search again in that unlock bootloader channel and use suitable one.

Hmmm, I am almost sure that the TWRP I've flashed was listed under Redmi Note 8 pro page. Can you please indicate more precisely where should I sera
EDIT: I think I've downloaded and flashed the correct TWRP file.
@Renate can you please detail your method so I can try to extract data from the phone?

1/Yeah it's official. You "flashed correct TWRP." Downgrade to Miui Android 9 (_9 in it's name) to boot into that TWRP and lose your data.
2/In unlock bootloader video above, search other video in his channel playlist and find TWRP video suitable for your Miui version.

Can't find the right video, can you kindly send me a link (I am on the latest Miui version and I am in Europe)?
In all the videos I've seen on his page he is using the device to install TWRP etc.
I think I just need the correct TWRP version for my MIUI release and then I'll flash TWRP and misc-reg.img. Is it right?
