Write/load the persist.bin from the backup you created with partition manager back to persist instead of the persist.img from .697 and see if it boots. Everytime I've flashed one of these I had to rewrite the backup of persist.bin to get past the corrupted prompt, even if I replaced the persist.img with the backup in the bundle itself.

Another idea: you can try RSA and be sure to change the region to China if there is an option somewhere. If a firmware bundle is found it more than likely will recover your modem partition successfully. I have done it with the Legion Duel 2 ~ Pro 2 without any issue.
[Lenovo Legion Phone Duel 2] chris198x:
Ok will give those suggestions a try, thanks again!
[Lenovo Legion Phone Duel 2] chris198x:
Ok finally made some progress. I was able to unlock the bootloader by getting sn.img from ZUI unlock site. Then flashed stock .697 ROM again. Phone is back up and running, but do not have the IMEI #'s. Trying to restore modem backups but getting Sahara error in QFIL now

How to get turbo charging to work in gsi rom?

I'm using latest evolutionX
[Lenovo Legion Phone Duel 2] project_2501:
Turbo charging is bad for the battery and hardware in general; a conveniece that doesn't warrant the costs.
[Lenovo Legion Phone Duel 2] project_2501:
Check within device manager and update the driver if there is a yellow exclamation displayed on the devices list to fix adb/fastboot first. Check that you have a com port selected within QFIL which may have been lost due to the devices identity having been changed, like described in my earlier posts. As for a qcn backup (assuming you did a backup prior to the flashing), have a read here.
[Lenovo Legion Phone Duel 2] billshuli:
After flashing some GSI roms and not be able to fix the sms isue, decided to return to stock. But after flashing stock, the device couldnt recognize the sim card. (all the stock roms) Tried many ways, but nothing. Locked the bootloader also maybe could be fixed, but nothing. After flashing stock with bootloader locked, the phone couldn boot. Sayng ``your device is corrupt wont boot``.Is bootloop in fastboot mode. Now cant boot to go to settings to give permition to unlock bootloader. Cant go to fastbootd, `` Failed to boot into userspace fastboot; one or more components might be unbootable``. Knows somebody some way to bring back the phone?

I'm planning to buy a new phone and eyeing on this one as an option. Does debloating the phone fixes the issue related on Messenger app? Do other apps like Teams, Skype have similar issue?

Thanks
[Lenovo Legion Phone Duel 2] iHackFX:
Greetings. I've made an application for a button in the quick settings to turn the battery bypass mode on and off. We checked the Russian community from the telegram channel, everything works well. Works in GSI and on Stock. I hope you appreciate it. I'll wait for feedback on the work)

There is a app

Can anyone tell me the best camera app I can use for this phone? I have tried multiple roms, but only one of the backcamera is being used at all times.

[Lenovo Legion Phone Duel 2] legiony70:
I have tried 4:

Pixel Experience

Cyanogen

They all have SMS issues and only find one of the 3 cameras at the back and no adaptive brightness. I would like a full functioning ROM if anyone knows one.

Dont get me wrong all these ROMS are pretty good... I just want to have all functions.
[Lenovo Legion Phone Duel 2] jeff19984455:
How to flash these roms in Y70? Thanks.
[Lenovo Legion Phone Duel 2] billshuli:
DON'T FLASH. You will end destroying your phone. In those roms is not working the sim card. After when will try to return in stock, will have problems. If you want to change things, try 4pda site. They have every thing step by step.

I am really tired with this phone, the stock rom start having problems with WhatsApp and messenger app, so I decided to use a GSI, I used the PixelOS GSI, but the VoLTE did not work even after trying all workarounds, previously I had used the AOSP Android 14 GSI with it and the workaround did work but for PixelOS did not work, then I went back to the stock rom using QFIL and now the phone still is not able to recognize the SIM card in slot 1 and sometimes it works in slot 2 with a bad reception, I am not able to understand what is the issue. Did the phone radio options persisted between going from GSI to stock rom? Do I need to go back to custom rom and uninstall the IMS app? Please someone help me, I am really tired with this phone and need to use the calling service.
[Lenovo Legion Phone Duel 2] billshuli:
Yeah, like some of us. Also i had a sim problem after returning from custom. Whatever you do, DON'T FLASH STOCK WITH LOCKED BOOTLOADER. Keep your bootloader unlocked, all the time. Try to check the 4Pda site. They have some cool solutions, but i have try.
[Lenovo Legion Phone Duel 2] aarkay14:
Thank you, I have now installed the Derpfest GSI, everything works, but I lose the radio signal sometimes if I reboot, I then just go to radio settings and turn off the radio and then shut down the phone, wait 1 min and turn back on and it works, the ROM is stable but sometimes the phh settings options stop opening or something happens. I will switch to an old phone for daily driver later and try to fix this phone, I know the QFIL way but is there any other way to completely erase everything and install the stock firmware like it was from factory? I understand that the radio also contains some firmware so can we really make it stock again? Someone needs to make a custom firmware specifically for this phone with such a great hardware..
[Lenovo Legion Phone Duel 2] Suriem:
Did you get the file? I need it too.
[Lenovo Legion Phone Duel 2] Suriem:
Do you have a qcn file for this device so I can edit and put the IMEI back?
[Lenovo Legion Phone Duel 2] aarkay14:
I have the QCN file from my phone, but if I give it to you then what will you do with it? is it legal?
[Lenovo Legion Phone Duel 2] aarkay14:
Just updating that the Derpfest GSI works very nice, it has a little bit of Micro stuttering but not always and it gets the job done, the network is also working fine, the PHH Settings UI crashed once on me, after reboot I saw all network was gone but then it got fixed after a reboot, so far so good, will use this phone until I can afford a better one, so far this is my Daily driver, if anyone wants to ask any questions then please let me know here. Also yes, there is no incoming SMS, maybe some issue in the ROM but I dont need it so I am Ok. LTE works, 5G I have not tested, Messenger and WhatsApp reboot issue has been fixed so I am Ok.
[Lenovo Legion Phone Duel 2] project_2501:
There is TWRP and a semi established custom rom build by Rinko Kagura here. As for your sim issues; did you do a backup of your QCN, persist, and modem (NON-HLOS) before you started messing around with GSI roms?
[Lenovo Legion Phone Duel 2] aarkay14:
Ohh.. I have QCN.. but I didn't take a backup of persist and modem (non-hlos).. please tell me what to do? Right now phone works ok.. but my SIM 2 shows as SIM 1 .. LTE works but SMS does not.. can you help?
[Lenovo Legion Phone Duel 2] project_2501:
GSI roms have had an issue with receiving SMS (RX) since day one; unless you use your device for purely media related apps and want the illusion of an up to date system (with SELinux set to permissive) GSI roms are a half baked solution for any device that needs to be fully functional and secure. Recovering your original persist is not a simple task, unless you're able to acquire and run the recovery software from Lenovo (mainland China version). The QPST firmware bundle should contain the only variant of NON-HLOS (modem) binaries needed. You can try to restore your IMEI #'s and persist partition by carefully following this guide with the current QPST firmware bundle available.

Depois de instalar a rom stock eu tenho o IMEI resetado. E depois de pesquisar descobri que para restaurar meu IMEI que veio na caixa eu precisaria de um arquivo qcn, editar com o IMEI que veio junto e retornar para o celular. Não sei como dizer se isso é legal. Estou tentando consertar um problema que eu mesmo causei, quase perdi meu celular porque não consegui desbloquear no zuiunlock depois de 3 semanas consegui mas sem o IMEI.

After installing the stock rom I have the IMEI reset. And after researching I discovered that to restore my IMEI that came in the box I would need a qcn file, edit it with the IMEI that came with it and return to the cell phone.

I'm trying to fix a problem that I caused myself, I almost lost my cell phone because I couldn't unlock it on zuiunlock after 3 weeks I managed to do it but without the IMEI

[Lenovo Legion Phone Duel 2] Suriem:
O que fiz ao telefone até agora foi. Após problemas ao reiniciar o celular no WhatsApp e Messenger devido ao OTA 772. Resolvi instalar a stock rom via QFIL mas o NOOB aqui não desbloqueou o bootloader antes. Fiquei com um celular congelado por 3 semanas. Durante essas semanas experimentei sn.img no zuiunlock. No entanto, meu celular tinha um número de série de 10 dígitos. E lá só aceita 8 dígitos. Então, depois de vários flashes e tentativas, não sei como meu número de série chegou a 7 dígitos. Graças a isso e a pesquisas no xda encontrei alguém que disse que bastava colocar 0 no final do número de série no site zuiunlock. Por conta disso consegui pegar o sn.img e desbloquear o celular, mas como coloquei apagar TUDO antes nas opções obtive IMEI zerado. E agora estou procurando um qcn para editar e restaurar meu número IMEI que vem na caixa do produto.

What I've done on the phone so far is. After problems restarting the phone on WhatsApp and Messenger due to OTA 772. I decided to install the stock rom via QFIL but NOOB here didn't unlock the bootloader beforehand. I had a frozen cell phone for 3 weeks. During these weeks I tried sn.img on zuiunlock. However, my cell phone had a 10-digit serial number. And there only accepts 8 digits. So after several flashes and tries, I don't know how my serial number got to 7 digits. Thanks to this and research on xda I found someone who said that it was enough to put 0 at the end of the serial number on the zuiunlock website. Because of this I was able to get the sn.img and unlock the cell phone, but as I put erase EVERYTHING before in the options I got IMEI reset. And now I'm looking for a qcn to edit and restore my IMEI number that comes in the product box.

[Lenovo Legion Phone Duel 2] faizalkojang:
I didn't install the GSI custom room, but I installed the stock room for my Lenovo Legion Y70. because this cellphone has a bug when calling WhatsApp, Instagram, Telegram. When there is an incoming call from that application, the screen flashes and finally the device restarts by itself. does that happen to you too?
[Lenovo Legion Phone Duel 2] aarkay14:
Yes! I was experiencing the same bug in the stock ROM so I moved to custom ROM and now the phone works fine. The only issue is that only 1 SIM works and SMS doesn't work. Also need to have root access to properly use all 3 cameras..so basically phone is running with less features.. going back go stock ROM did not solve my WhatsApp and Messenger problem. Phone kept rebooting, so I finally moved to custom ROM derpfest! It is very fast and work fine with the issues I posted above. But now WhatsApp and Messenger work so its ok.
[Lenovo Legion Phone Duel 2] Suriem:
I say diagnostic mode to use QFIL to restore qcn, like you did on yours? Here I am having difficulties. I just need to restore the file.

2. open the file (automatically goes to flashing room)

The process takes about 10 minutes.
[Lenovo Legion Phone Duel 2] aarkay14:
its here: https://derpfest.org/

Please make sure to set the screen to 120 Hz display, that way it does not stutter, there are some fixes still needed, but it is a GSI so you have to understand that it is not like 100% calibrated for the phone, but it works fine. I am using it as a daily driver and it rocks, I will try to work on the ROM and build a better version straight for the Lenovo Legion Y70, it is a fabulous phone and should serve me for the next 5+ years or so, we can always update the GSIs and the phone will work, mine has 16GB RAM and 512 GB storage so it should last unless I break it. All things works, the LDAC and BT all work. If you face issues with LTE then go into radio settings, turn off both the radios and then reboot the phone, it will work fine on next reboot. Just keep it running, I love the customization options on this GSI as well so you can enjoy different fonts and stuff..

To get the OTA update 14.5.808 ST, install the VPN app (see attached, just search China VPN in Play Store), open it, register, and after it runs go to System Update and it should find the 80 MB update. The update took a long time (a restart is also required) to finish so be patient. Only English and Chinese languages are available.

[Lenovo Legion Phone Duel 2] project_2501:
You do realize that if the bootloader isn't already unlocked that it is now not able to be unlocked Red Horse pa more ? The binaries have been removed, it's advised for anyone thinking of updating to download the update and move it off the device (do not install it), followed by immediately unlocking the bootloader (standard and critical), and then manually update by using local update from the app. Keep in mind the device will wipe during the unlock procedure and you'll no longer receive OTA updates.
[Lenovo Legion Phone Duel 2] Red Horse pa more:
Wow, that's a lot of commentaries from me just saying that I'm already at the latest ZUI for Y70. I only posted that so other Y70 users are informed of the availability of that ZUI version as info for this device are very scarce. Since I bought the device (brand new) and updated several times, my system was not wiped (I did nothing to the bootloader). To other users who wish to update, it's up to them but of course care and research should always be done.
[Lenovo Legion Phone Duel 2] project_2501:
For some, having root is not important I guess? For those that understand the consequences of updating from 14.5.808 to ZUI 15.0.375 without an unlocked bootloader, here is the update which can be applied manually through Update Manager by tapping the upper right three dots and using local update (remember it needs to be renamed update.zip and placed at the main directory of storage (/storage/self/primary)).
[Lenovo Legion Phone Duel 2] Black4ng3L:
Good Day Sir. Is there still a way to open the bootloader when it's on ZUI 15? Is force unlock bootloader is possible?

I'm trying to contact the lenovo cs and waiting for their response because in zui.com/iunlock only allows 8 digits of serial number but mine have 10 digits.
