Lenovo Tab 10 TB-X103F always get stuck in the bootloader
I had all the files together, went through this tutorial several times and finally wanted to flash my LENOVO. All the work just to realize that the bootloader is not working. No chance. I've tried everything. The tabet always got stuck in the bootloader. So I sent the broken tablet back. I would have liked to try it once!

This 100% worked for me on my lenovo tb-x103f thank you!

Hey, I have a question.
Is this also for the
1GB RAM
16GB ROM version.
This question because, I see that stated the 2GB version but I really want it on my 1GB version.
Thanks in advance.

ADB-driver problem
Hello, I tried to follow this guide, but I am not able to install adb driver. I tried to use Windows driver (Win7), and also Lenovo drivers (Lenovo Driver: When I connect the tablet it is also shown as a Disk-drive. Inside that there is a Lenovo driver app). But anytime install adb-drivers failed. I also tried Clockworkmod universal drivers, but also this has not worked (maybe I did something wrong).
Because of that missing adb driver I cannot install TWRP (of course I enabled in developer options of tablet the USB debugging).
Has anybody working drivers or any idea to solve this problem?
Greetings Odiad.

none of the custom roms install on my tab,i read the install script is bad?,is this true,i get error 7 msg every time,can this be sorted?

Hey,
Two questions:
I got an issue with my camera working, can't connect to the camera and
had some zip error for this addonSu in TWRP, zip verification failure. Is this something you recognize?

Hello Good People,
I am trying to flash TWRP to my Lenovo Tab E10.
I can only complete step C
When trying to perform step D I get this message:
Booting
fastboot error: Command failed
Can someone please tell me how to resolve this?
T.I.A.

i get to step 1d and it just stays in the lenovo boot up screen (black screen with orange lenovo logo in the middle). any ideas?

Hello,i have the 1 gb ram version and i am realy new to all this
I do not have external storage so i am using internal storage for the files.SO far i have managed to install twrp 3.0.2,supersu and lineage os 14.1 but i can not istall the open gapps.
The error message is" Failed to map file(path,filename)" and "Error installing zip file (path,filename).
I tried to flash open gapps after flashing lineage and after rebooting having lineage flashed.
Any suggestions?

Hello! My name is Brandon and I'm 29. I have been studying, reading and learning (still am.) everything I possibly can about all the different possibilities that are available when it comes to electronics in general. I tried to unlock and flash my Nextbook ares 11 but I only accomplished unlocking the bootloader, So I do what I do best and kept it persistent because persistence always prevails! I searched some more and I found this thread and it just so happens there was a Lenovo tab 10 tb-x103f laying around so I gave it a shot and . . . . . . . . BOOM!! I accomplished every step and it now operates with Lineage 14.1 OS! I ran into some similar issues that are listed above but I held to and I was able to come out SUCCESSFUL! I just want to say THANK YOU soo very much for the knowledge and putting un-corrupted software on here. This is a huge accomplishment to me and I shall continue with being persistent lol

Can anyone please please make a pie update custom ROM for lenovo tab 10 tbx-103f. Many people use it and hate getting stuck at 7.1. I'll provide all information required. My tab has bootloader unlocked twrp installed and with root. If anyone wants to make a custom ROM(Any ROM) pie update for this device. I'll provide all info about this device. [Sorry if my English has some grammar mistakes.

Hola, tengo la versión de 1 GB de RAM y soy realmente nuevo en todo esto
No tengo almacenamiento externo, así que estoy usando almacenamiento interno para los archivos. Hasta ahora he logrado instalar twrp 3.0.2, supersu y lineage os 14.1 pero no puedo instalar los gapps abiertos.
El mensaje de error es "No se pudo asignar el archivo (ruta, nombre de archivo)" y "Error al instalar el archivo zip (ruta, nombre de archivo).
Intenté abrir brechas abiertas después de flashear el linaje y después de reiniciar el linaje parpadeó.
¿Alguna sugerencia?

Funcionó perfecto.

thanks you so much, for, post here, works , all ok.

After flashing this ROM to TB-X103F 1gb Ram ( Wifi only ) the touch calibration completely wrong.
While in TWRP touch works normally.
e.g. the screen is vertical but the touch as if the screen is horizontal and the opposite the same.
How to solve this. I've tried most of the custom roms available all with same issue.

Install Magisk on PX6 (Working on Xtrons)

Hello, I have successfully installed Magisk on my Xtrons PQ80UNV. All you need is a smartphone or tablet with Magisk, a PC and a USB A-A cable
- extract the boot.img from the update.zip
- on the smartphone patch the boot.img with magisk ( you find the patched file in the download folder )
- connect the radio on usb 1 with your pc over the USB A-A cable
- Reboot to recovery
- select bootloader
- on pc write "fastboot reboot"
- write "fastboot flash boot magisk_patched.img"
- write "fastboot reboot"
- install magisk manager on the radio
and if all correct, you have working magisk
good luck ^^

Hello! Where do I find downloads to do all this? You can be a little bit more detailed in the steps? ?I want to perform this procedure for my PQ80UNV
Ciao! Dove trovo download per fare tutto cio? Puoi essere un pochino più dettagliato nei passaggi? ?Voglio eseguire questa procedura per il mio PQ80UNV

This worked on my Dasaita Vivid 11. The first time I tried it, I ended up in a boot loop after I restarted from within Magisk. However, following the steps on page 7 got me to a rooted head unit.

my adb-fastboot doesn't recognize my smartphone

Hey guys, I was trying to root my smartphone using magisk, so I downloaded the stock rom and got the boot.img file for magisk to modify, passed the modified file to the computer and put my device in fastboot mode, but adb-fastboot didn't recognize my device even though I installed the google drivers, so I decided to install the manufacturer's own drivers, but it didn't work, I went to several forums and nothing, so please help!

seems to be a reoccuring problem to us. steps as show:​​1. press the windows key + r at the same time to open the "run" window.​
2. type "devmgmt.msc" and press enter. it should give a device management window in a few seconds.​
3. if the phone is in mtp mode, it will appear under portable devices/mobile devices. right click that and select "update drivers." click on "search drivers in my computer" and then select "allow me to choose from a available drivers list from my computer." scroll down until you see "mtp device" and double click on it. just click on "proceed". if it fails, try it again but with different drivers.​
make sure to have usb depuration on and reboot to fastboot yadda yada badlaldaaa
then update fastboot drivers "device may be on android phone "'''make sure to install motorola drivers or built in fastboot drivers''''' and then proceed

no matter how much you manage to install drivers you will not be able to root your moto e6 play, (BOOTLOADER IMPOSSIBLE TO UNLOCK UNTIL THE MOMENT)
and do not come to say that it is due to drivers or because we are using an incorrect method, etc.
fastboot oem get_unlock_data not working
fastboot oem unlock does not work
fatboot flashing unlock and unlock_critical either
and it does not appear as waiting for device
appears as remote: unknown command
so it is a problem of the bootloader and not the user

G.Kart said:
não importa o quanto você consiga instalar os drivers, você não conseguirá fazer o root no seu moto e6 play, (BOOTLOADER IMPOSSÍVEL DE DESBLOQUEAR ATÉ O MOMENTO)
e não quero dizer que é devido aos drivers ou porque estamos usando um método incorreto, etc.
fastboot oem get_unlock_data não funciona
fastboot oem unlock não funciona
fatboot piscando desbloqueio e desbloqueio_crítico também
e não aparece como aguardando dispositivo
aparece como remoto: comando desconhecido
então é um problema do bootloader e não do usuário

Yes, I searched many forums and it really is practically impossible to unlock the bootloader, but I have a question, is it possible to root using the sp flash tool?

General Nokia G21 development

Hi all!
DEVELOPMENT IN PROGRESS​
This thread is not to talk about HMD/Nokia and its policies.
The goal is to extract vendor files to build an AOSP ROM. Also, to unlock bootloader and root the device for developing purposes.
At the moment we know that:
-Nokia doesn't includes commands like "fastboot oem unlock" or "fastboot flashing unlock" in their bootloader (but includes oem unlock in developer settings).
-Without unlocked Bootloader we cannot flash custom recovery or root our device.
-adb shell cannot elevate privileges without root. Then, we cannot extract vendor files (completely).
-Android 11 patch is in february. March patch not released.
-Device codename is SCP_sprout, model TA-1418.
-We must be cautious with the information we publish.
Testings:
-Extracted vendor partially as img.
-Still searching for vulnerabilities to gain temporary root access.
That's all, for the moment.
I have no much time to spend in it. Please, be patient.

I've created 3 new repositories in github for new data when available
device_nokia_SCP_sprout (to upload device tree)
rom_dump_nokiaG21_SCP_sprout (to upload whole stock rom img)
vendor_files_nokiaG21 (to upload vendor files (blobs)). This repo is temporary. The final repo would be proprietary_vendor_nokia_SCP_sprout

I think I've found your repos on github, but they're empty.. I'm trying to figure out of how re-enable the standard FM app (It's probably disabled because I'm in Italy where's there's a silly law prohibiting FM devices without DAB support)

Hi. Can anyone help me updating to A12 using adb sideload?
The problem is whenever I type adb reboot recovery nothing happens
If i try adb reboot fastboot i get into fastboot mode and then type fastboot reboot recovery
I get into recovery but it does not have any option to apply update from adb . The only 3 option i get is 1. Reboot bootloader 2. Reboot to fastboot mode and 3. Power off

From what I know, then maybe I'm wrong, Nokia from a security patch of 2018 made it ALMOST impossible to unlock the bootloader and enter recovery

In Italy with the Android 12 update now exist a recovery and a fastbootd (not fastboot) for Nokia G21

Fastbootd is useless if the bootloader is locked. How about the recovery mode? Do you have useful options inside of recovery?

singhnsk said:
Fastbootd è inutile se il bootloader è bloccato. Che ne dici della modalità di recupero? Hai opzioni utili all'interno del recupero?
Click to expand...
Click to collapse
If you want to go to recovery you have to enter FastbootD with this command: "fastboot reboot fastboot".
In FastbootD, enter recovery.
The recovery is empty, there is only rebooting the system, enter fastboot and shut down.
(Sorry for the bad English)

But I think that with the Android 13 update (I don't know when it is) there will be more things in recovery and more commands for the classic fastboot mode.

Not Possible with this update.

Question Dm-Verity corruption

Hi everyone, i have the dm verity corruption on my xiaomi 11 t, it is my main phone so i need to fix it, i wanted to unlock the bootloader, but i have family link that blocks that option, so i booted it into fastboot and typed:fastboot reboot fastboot, as said from the guide, but then the phone rebooted in fastbootd, i didnt know what that was and i typed fastboot reboot and it showed the DM verity error. Is there any way to fix it?

Hola a todos, tengo la corrupción de dm verity en mi xiaomi 11 t, es mi teléfono principal, así que necesito arreglarlo, quería desbloquear el gestor de arranque, pero tengo un vínculo familiar que bloquea esa opción, así que lo inicié en fastboot y escribí: fastboot reboot fastboot, como se dice en la guía, pero luego el teléfono se reinició en fastbootd, no sabía qué era eso y escribí fastboot reboot y mostró el error de verdad de DM. Hay alguna manera de arreglarlo?

I found the solution, at this point I assume you have abd and fastboot drivers installed so:
1.- fastboot devices
2.- fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
3.-fastboot reboot

Look with these 2 programs I instantly recovered my bricked cell phone, it even allows you to downgrade if you wish, both are free
The one that says TFT allows me to flash the complete ROM, but the bootloader will block you again, the second one that says MTK Meta Utility is used to unlock the bootloader without having to go through xiaomi

What guide? And yes, this command boots into fastbootd mode. That's not more than a binary in your recovery and won't brick your device when it gets executed. Also a reboot from fastbootd won't brick it.
To avoid serious damage on your OS and your device, you shuld try to flash a complete firmware.

BTW: your device is in "Red state".

I dont know, maybe i flashed something? because the device said not allowed in locked state, but i couldnt do fastboot oem unlock, i needed to enter the os, btw thanks yall for the collaboration, the phone is booting, but it is in unlocked state, i gived the phone in a repair centre to lock the bootloader. Thanks again.

your device is locked in family link. it's a brick. service center can help flashing ROM. MTK - Auth Bypass (SLA/DAA) could maybe work too (at least chipset is supported)
