Eu venho tentando desbloquear o bootloader do tablet a 1 semana. Finalmente consegui!

Não fiz todos os passos que você colocou aí. Consegui desbloquear pegando a imagem dele na internet.

1° Descobrir que o QFIL é para abri-lo no caminho "C:\Program Files (x86)\Qualcomm\QPST\bin" dessa forma funciona sem dar erros.

2° O erro do sahara no QFIL eu descobri que era algum bug de instalação de algum programa para solucionar o bootloader bloqueado, reinstalei o drive da qualcomm para reconhecer o tablet no pc e reinstalei o QPST.

3° O site da zui.com/unlock para o tablet está trancado. Consegui um "sn.img" pelo link de um usuário em outro tópico aqui no XDA. Só preciso colocar o número de série do tablet na url e baixou em seguida a imagem com tamanho de 6kb, os aquivos de imagem que baixei antes desse e sempre davam erro no ADB para desbloquear o bootloader tinha 8kb.

4° Todo o fórum aqui no XDA ajuda consideravelmente para auxiliar os leigos como eu a alterar e restaurar a ROM do tablet.

5° Meu problema foi que eu não gostei da atualização da ZUI 14, pois tirei o modo pc e aba rápida que tinha na versão da ZUI 13, então eu fui restaurar a versão original, a stock rom, a GSI rom, são a mesma coisa. Depois de restaurar a stock rom eu queria atualizar para a ZUI 13 novamente então consegui que bloqueando o bootloader de novo as atualizações viriam automaticamente, foi aí que quando eu bloqueei o bootloader veio o erro do dispositivo corrompido.

Enfim consegui colocar a ROM no lugar novamente e o sistema iniciou finalmente depois de 1 semana tentando e pesquisando a respeito. Muito obrigado a vocês que compartilham seus conhecimentos para quem não sabe. Ajudam muito !

Hi,

In the step "17. Back to QFIL : inject back your serial number backup in partition "fpinfo"" I just need to load the original fpinfo? Is it necessary to load the original frp too or not?
[Android General] solopsd:
Hi, I'm trying to do this on the TB128UF but I don't get the fpinfo, any solution? Thank you.
[Android General] huracancun:
I block the bootloader and im in a loop, I try to connect with the ADB and not recognizes it and the only thing that i know to do its load the sn.img, but the page is down, what i can do? Can I edit other sn?

My sn is HA1HJC10

http://cdn.zui.lenovomm.com/developer/tabletboot/[your sn number]/sn.img
[Android General] f1tm0t:
Your case is described in first post.
[Android General] Philipe.ost:
Hello. In the screenshot I changed the "ssd" file to "fpinfo" by mistake. I did the process and reset the original rom, the tablet is unlocked but does not start, I believe that because of this changed file, it is in a looping.

Could someone generate the ssd file in ".bin" so that I can perform the replacement on the partition?
[Android General] f1tm0t:
What version of FW? Must be no matter, mine is from 14.0.127 ZUI
[Android General] Philipe.ost:
I couldn't replace the file because I can't access it anymore. It now displays this message.
[Android General] Philipe.ost:
The tablet starts in fastboot mode and showing unlocked status.
[Android General] f1tm0t:
Toggle radio button on Meta Build, choose needed files; after go to Menu -- Part Manager.
[Android General] Philipe.ost:
I managed to replace the file and reinstall the system. Tried ZUI 12 and ZUI 13 selecting "Reset State Machine" in FireHose Configuration, giving same error and looping on startup showing "lenovo".

In the QFIL application it gives an error "Get Partition Files Failed:MetaCli not found !!!".

In the system, it even enters Android Recovery, but when selecting the factory reset, it returns to the same screen.
[Android General] f1tm0t:
On my experience and mind it is PC/windows error, not tablet. Google it for solution.
[Android General] juyran:
Thank you so much. My device is alive again.

In order to lock the bootloader again without trouble, do I have to change back my sn and do I have to change back that last byte to 0 again?

Hi guys!

FIrst of all, when the XiaoXin Pad arrived to me, I saw on app DRM info that widevine is L3 and global rom... I changed de system to CN version (TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_13.5.365_ST_220526_qpst ) and widevine still was L3, so I have locked the tablet and it semi bricked the tablet. So after hours trying to return to normal, I unlocked the tablet again and QFIL the CN ROM again (TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_13.5.365_ST_220526_qpst ) and updated the CN ROM to latest version.

01. TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_13.5.365_ST_220526_to_TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_13.5.395_ST_220617

02. TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_13.5.395_ST_220617_to_TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_13.5.476_ST_220805

You can download the updates here.

After it, I locked the tablet and the system is runnning normally and widevine L1 is there, everything alright. Thanks guys.

Hello fellow friend,

"Corrupted device" NO LONG

This guide is targetted at those who like me, locked their bootloader and got the message : "corrupted device blabla

And are desperate as Lenovo doesn't answer when we ask for the unlock file via the ZUI unlock website

Well, it is possible to change your serial number temporarily to unlock your bootloader with a known file for this serial. And this how you do it

1. Go into EDL mode (hold down volume up and connect to P

2. Launch QFIL, go to Tools -> Partition Manager (make sure you have selected the correct programmer prog_firehose_ddr.elf from the Chinese ROM

3. Right click on the partition "fpinfo" -> Manage Partitio

4. Click read dat

5. Backup the data (it contains your serial number), you can find it in : AppData\Roaming\Qualcomm\QFIL\"your folder" mine is COMPORT_3 (the file contains the start adress of the partition : 0x2208

6. Open a copy with an hex editor like HxD and modify your SN to HAHAHAHA (make sure your file is the same size as the original

7. Back to QFIL : Load the modified file to the partitio

8. Right click on the partition "frp" -> Manage Partitio

9. Backup the data (file 0x2188

10. Open a copy and change the last byte from 00 to 0

11. Back to QFIL : Load the modified file to the partitio

12. Download sn.img for HAHAHAHA from her

13. Boot your tablet into bootloader mode (check the new SN

14. fastboot flash unlock sn.im

15. fastboot oem unlock-g

16. CELEBRATE because your bootloader is unlocked

17. Back to QFIL : inject back your serial number backup in partition "fpinfo

18. You can go back where you left -> Flash the Stock Chinese RO

Check your Qualcomm driver. Also, take a look at windows device manager to see if the device is properly recognized by the PC.

Maybe try to open QPST, close it and then open qfil

Hello!

I have a Xiaomi mi note 10 pro. This morning my phone was off, when i turn it on, it will automatically shut down.

I narrowed it down to : If the cellular data is on, the phone will shutdown in seconds. If I'm in airplane mode, I can use the phone just fine, even with Wi-Fi on.

I tried to restore it to default, nothing changed. My next step would be to unlock it and install a new ROM/OS, but I need to wait 7 days to unlock my device.

Any help would be appreciated! Thanks!

Greetings everyone!

Just got my Pixel 6a, love it so far, but i have one problem: Wifi Call doesnt work.

Whenever i try do a wifi call, i just get the message "out of network call"

Im using a german sim card from o2 (telefonica) and the thing is: my prior phone

was a redmi note 10 5g and with this phone (same sim card) wifi calling just worked like a charm.

so my question is: is there any trick to make it work? any explanation why it doesnt work with the 6a?

its a real bummer to go from a cheap a... redmi where this function just works fine to a nice and not so cheap pixel

(love google phones by the way, its my 3rd one), just to realize that something doesnt work as excpected.

i also tried a different os (calyx os), still no wifi-call.

help?
[Google Pixel 6a] Deleted member 2044343:
I'm using the Pixel 6a in Germany with o2 too - I've no issues with VoWifi and VoLTE. Are you shure you've enabled WLAN call in the accordant settings?

[Google Pixel 6a] realCyphox:
i wrote that i used wifi calling with the redmi just fine, so i guess i know how to set it up, yes. so far i tried two o2 cards, no luck. question is, can you (you) really do phone calls by wifi or are you just using cellular without actually knowing. can you still do phone calls when airplane mode is on but wifi is enabled? do you see the wifi-icon onscreen (below number/name you're calling) when making a call?
[Google Pixel 6a] Deleted member 2044343:
