Hi all,

Can someone share "y700(TB9707F)_zui_v14.0.286_edl_v2.0" please? All the links are dead ((

I tried to recover my tablet using: QPST_2.7.496.zip, Qualcomm USB Driver V1.0.exe, "TB-9707F_CN_OPEN_USER_Q00235.1_R_ZUI_13.0.586_ST_220222_qpst.zip".

Used two different cables, two laptops. The behavior is the same.

Anyone know how to fix this error when i click button download to up stock rom
[Lenovo Legion Y700] Nerrew:
How bricked I am?

I updated to Zui 14 and wanted to update to Zui 15 immediately and I'm pretty sure I forgot to turn on USB debugging before going from 14 to 15. ADB doesn't see the device anymore. Is there anything I could do to solve this? There is a sound of a device connecting when I plug it in, but I'm not seeing anything in Device Manager. It doesn't turn on and it holding up volume and power button does nothing as well. In the video guide(s) I reached the spot where you turn it off and plug in holding the volume up button, only it flashed 'lenovo' instead of just the backlight.

Edit: I found it in device manager as 'Qualcomm HS-USB QDLoader 9008'

EDIT 2: I finished reading the thread went back and did the holding all buttons for a min. It didn't work immediately, but when I pressed up and power afterwards that worked. Imma go cry sum now, that was an exhilirating first foray into flashing my devices. Thank you all for the thread.

I Have Lenovo Y700 (TB320FC) and i wanted to try the Global rom. I had download the Rescue and Smart Assistant in order to get the stock rom. I let the app run and "rescue" my device, but i forgot that my bootloader was locked and now im stuck in the bootloader screen. I tried running fastboot commands to unlock it without success. I tried flashing other stock roms in edl mode but nothing changed.

Can i fix it or its DEAD ?
[Lenovo Legion Y700] TTGHD:
i was under the impression you can flash the global rom without unlocking the bootloader?
[Lenovo Legion Y700] Onimusha117:
Did you manage to unbrick this?
[Lenovo Legion Y700] Giorgosfl:
My issue was because of the "Anti-rollback". To fix that i flashed the NEC 15.0.022 which it had rollback index and managed to save it.

hello everyone, I have the Y700 (2023) TB320FC, last week I updated to the latest CN ROM version, I wanted to try the global ROM since no longer the apps can be set it to my language, I used the Lenovo RSA to rescue to the Global Version but now the tablet shows the message "Your device is corrupt" and it won't boot, I have tried the NEC 15.0.022 but with no luck, can anyone help, does anyone have the latest CN ROM to try flashing it back to the version it had before.
[Lenovo Legion Y700] goolby:
Try to follow this link and unlock your bootloader and after that either flash the firmware from that link or use RSA to flash latest NEC or RoW Global Rom but remember not to relock the bootloader because of the rollback index...

You can use also this link as a guide for the Global Rom.

Most likely when you updated to the latest CN ROM the rollback index changed and because your bootloader is locked, it triggered the rollback index "Your device is corrupt" when you updated to NEC 15.0.022 which has a lower index.
[Lenovo Legion Y700] Onimusha117:
If you can unlock the bootloader, try to unlock and flash it with NEC Japan room first. Else... Like me, you have to wait for the next global rom or japan rom.
[Lenovo Legion Y700] SoyPeterCO:
Thanks for the reply, unfortunately I had no luck, the commands to unlock the bootloader won't work simply, I guess the tablet is bricked, I'll just have to wait until a new ROM come out, too sad :(

Let me know if you get lucky and manage to unlock or else anything that works to make it useful again.
[Lenovo Legion Y700] Breed43214:
It depends on version of the current firmware you're flashing over. Until recently, the official Global ROM had the newest security patches, so there was no need to unlock.

Now, the latest CN ROM (774) has higher security patch (05/01/24), and hence rollback index, meaning anti-rollback kicks in if you flash with locked bootloader. It also looks like 774 (and the .761 before it) prevents you from locking/re-locking the bootloader too.

To go back to this table that has been posted a lot now:

Anyone importing this from China should ensure the current firmware is less than .761 (not in the table, but I believe also has a higher index than Global .139!!!) and make sure they do not do an OTA if they are planning on flashing Global ROM. You do not need to unlock the bootloader in this instance when using RSA.

If you are on .761 or above, even flashing Global with an unlocked bootloader can result in a brick according to this website. Best not to do it.

Anyone with a bricked device will either need to wait for a later version of the Global ROM to be released and then flash again via RSA and it should be recoverable.

Alternatively, getting your hands on the files for CN 15.0.774 ROM and flashing back to that manually is potentially an option, if possible.
[Lenovo Legion Y700] TTGHD:
thank you for that super informative post. i called myself researching before i ordered it, but i got my tablet. opened it, didn't bother to check any kind of version of CN rom or unlock bootloader, i just turned on USB debugging and flashed the global rom. everything worked perfect, but i see how horrible it could have went...lol
[Lenovo Legion Y700] Onimusha117:
You dodged a bullet man. :) I took one, and I have a cool thin brick with looping menu on top.
[Lenovo Legion Y700] TTGHD:
that sucks bro, was yours unlocked out of the box? and the second they release a updated global rom with security updates you'll be able to flash it no problem right?
[Lenovo Legion Y700] Onimusha117:
No, mine is full chinese rom. My box is fully sealed. :)). It was 373 but I accidentally updated to 774 before I used RSA to flash global firmware. Needless to say how speechless I was when the tab got bricked. Lolz

I hope it could be unbricked with new global firmware or Nec one. It's doable, but only time will tell.
[Lenovo Legion Y700] Ninachan:
I heard that the latest version of NEC's ROM also includes an anti-rollback system. It might be best not to expect too much. I have flashed the NEC 15.0.022 version to make sure there are no issues. Also, at the current time, the version provided by RSA is also NEC 15.0.022. However, we don't know when it will be updated in the future, and we also don't know if RSA can be used in that state.
[Lenovo Legion Y700] Onimusha117:
For what I read, Anti-rollback only locks the device when you installed a firmware with older security patches than the one on the device. It should be fine with firmware from the same or later patches.

For RSA, I tried to flashed RoW and NEC multiple times using RSA so I think it would work just fine. I only need Lenovo to push the latest rom out. :)
[Lenovo Legion Y700] ZA12GN1:
Does anyone happen to have an image of the official CN 774 ROM? I just received my Y700 2023 from AliExpress today, and then I naively updated the system software prior to trying to flash the global ROM through RSA. Like other people have described, the device is now stuck in fastboot mode with a locked bootloader; I've tried several methods to fix it but have not been successful. Out $400 :(
[Lenovo Legion Y700] Ninachan:
I forgot about security patches. Sorry for giving a wrong answer.
[Lenovo Legion Y700] Ninachan:
Even if someone has a CN 774 ROM, can a device stuck in a fast boot loop be repaired using RSA?
[Lenovo Legion Y700] ZA12GN1:
I was thinking after obtaining a 774 ROM, it may be possible to flash it through EDL mode instead of going through the RSA tool. Another possible method is that if you look in C:\ProgramData\RSA\Download\RomFiles, there is a folder that RSA uses to store the global ROM that it downloads before it gets flashed on the device. Potentially, it may be possible to somehow replace the IMG files in that folder with those of the 774 ROM in order to trick the RSA tool into flashing it.
[Lenovo Legion Y700] ZA12GN1:
Also, to my understanding, flashing any other custom ROMs like crDroid or Lineage through EDL also would not work, since those ROMs are modded based on versions older than 774 right?
[Lenovo Legion Y700] Onimusha117:
Yeah... Older security patches on top of 774 means bricked. :)
[Lenovo Legion Y700] PlasticCatto:
AOSPA requires .737 firmware, I have .139 installed. Managed to flash only the firmware without triggering anti rollback and got AOSPA working.

FYI .139 has higher security patch (dec 2023) vs .737 (nov 2023)
[Lenovo Legion Y700] project_2501:
Yes, by flashing the original CN .677 build with QFIL followed by unlocking the bootloader.

[Lenovo Legion Y700] Onimusha117:

[Lenovo Legion Y700] goolby:
It's actually March --> 2024-03-05 so it should have higher rollback index than 774 --> 2024-1-5...

The date should be YYYY-MM-DD.

I think that you are in luck 😀
[Lenovo Legion Y700] Breed43214:
The Play System updates are entirely unrelated to Security Patches releases:

It's the Security Update which is March as mentioned by goolby. If this is released via RSA, there should be no reason it won't put an anti rollback bricked tablet right.

Anyone installing .240 on a blocked tablet once released on RSA, let us know how you get on!

I've just went from .139 to .240. Nice to see the new battery maintenance mode of 80-95%. The charge protection of 40-60% was too strict for me to use.
[Lenovo Legion Y700] ZA12GN1:
Does anyone know when RSA will be updated to the .240 version?
[Lenovo Legion Y700] Onimusha117:
I'm waiting... STILL .139

Also, anyone has the old version of RSA? the new 6.9.3.7 is too laggy.

EDIT: The non-buggy version could be found here: Motorola site

[Lenovo Legion Y700] Onimusha117:
hmmm.... Thanks for the head up. But I find it weird. All other patch date start with day 1, and .774 start with day 5? Any one can double check this? Also, today is still not May yet.... I don't see the update date makes sense. lolz
[Lenovo Legion Y700] Breed43214:
As goolby stated in the post you quoted, it's not May. It's March.

2024-03-05

I.e. 05/03/2024

5th March 2024

Which is higher than .774's 2024/01/05. i.e. 5th January!

Although, strictly speaking, the 01 and 05 do not represent days. They represent AOSP updates (01) and AOSP+Vendor and Kernel fixes (05).

What's the point of doing this? I checked and mine was 'NO SET' so decided to changed it to UK.

From what I can tell the only changes I can see is the UK Keyboard is set to default option in initial set up and you get a lot more bloatware (all which can be removed - mainly games) after set up.
[Lenovo Legion Y700] ZA12GN1:
Hey everyone, I managed to figure out a method to unbrick the devices with the bootloader locked. For anyone with the device stuck in fastboot due to accidentally flashing the RSA global 139 ROM over the CN 774, here's what I did:

1. Go back to RSA, purposely redownload the ROM files for the global 139 version. The files will be stored in: C:\ProgramData\RSA\Download\RomFiles\TB320FC_ROW_OPEN_USER_Q00031.0_T_ZUI_15.0.139_ST_240205.

2. From the "test" Google Drive link shared by terajima-alc, download the 7Z file of the CN 774 ROM.

3. Now, go to C:\ProgramData\RSA\Download\RomFiles\TB320FC_ROW_OPEN_USER_Q00031.0_T_ZUI_15.0.139_ST_240205, and directly extract the contents of the "images" folder within the 7Z file into this directory. Replace all of the files when prompted.

4. Go back to RSA, and repeat the same process as usual to flash the device.

The tablet will be back on the 774 ROM, fully unbrick and ready to be used again. :)

Through this method, I successfully tricked the RSA program into re-flashing the 774 ROM instead of the global 139 ROM.

Thank you so much to terajima-alc for sharing these files with everyone! My device is now unbrick! :)

EDIT:

Updated ROM links:

@Breed43214

774: https://mega.nz/folder/RdAnzSgb#JZl7FJTa_W4WllsnoJKzwA

@rydeen8

795: https://mega.nz/folder/orVzVBBa#89NvOEyEX2OgOKQtSxhr5g

If you were on CN 795 before bricking your device, you will have to refresh the 795 ROM.
[Lenovo Legion Y700] ZA12GN1:
Something else I want to mention is that initially, I tried the process I described with the global 240 ROM shared by terajima-alc as well, but the device would not even boot into fastboot mode at all after that, it would throw the error: "the current system is not compatible with hardware, device will power off automatically".

I then repeated the process with the 774 ROM files and successfully unbroke my device, so do not replace the RSA files with those of the global 240 ROM, instead, focus on getting the device fixed and back to the stock 774 first.
[Lenovo Legion Y700] ZA12GN1:
One more thing though, I am trying to unlock the bootloader now that I'm back running on 774, but I'm still getting the error:

FAILED (Write to device failed (no link))

fastboot: error: Command failed

This is occuring even though I have the correct developer settings enabled. I'm really trying to unlock the bootloader so that I can get the device to the correct global ROM now. Anyone know what to do?
[Lenovo Legion Y700] Breed43214:
Nice. I did think if someone could get their hands on the ROM files, this could be done.

Interesting that you couldn't flash .240 Global ROM directly over the top. You could try unlocking the bootloader, now that .774 is running, then flash .240 and try relocking.

It may or may not work.

I wonder if Lenovo are trying to close down the ability to move from CN to Global?

*EDIT* - You beat me to it!
[Lenovo Legion Y700] Breed43214:
@Ethys was getting the same issue, but I think managed to fix it? Might be worth a DM to them.

Are you using the Motorola drivers?
[Lenovo Legion Y700] ZA12GN1:
Yes, I also tried on both Windows and Ubuntu. Same error message.
[Lenovo Legion Y700] TonySpumoni:
Wow!! I can't thank you enough. I really thought my device was bricked forever. This is an absolute genius way to get the CN firmware back on. I spent almost 5 hours yesterday trying to figure this out. I have never posted in this forum, but I created an account just to thank you! You are brilliant! Thank you!!

[Lenovo Legion Y700] Onimusha117:
Someone actually tried and bricked the devices. Lenovo seems to lock the devices somehow.
[Lenovo Legion Y700] Breed43214:
I think from .774, the bootloader has to be unlocked to move to Global now.

Using RSA method above, flash .774, unlock the bootloader, then flash .240 via fastboot (not RSA), then relock.

Could you share with me a guide to get the rollback index from a downloaded rom please?
[Lenovo Legion Y700] ColDHuy:

[Lenovo Legion Y700] dieandromeda:
774 -> 240 = error

774 -> 737 = success

737 -> 240 = error

774 -> 022 = success

022 -> 240 = error

774 ->139 = untested
[Lenovo Legion Y700] Breed43214:
There's some stipulations to the above. For example 737 -> 240 only fails if you've previously installed .761 or .774. Something in those prevents moving to Global ROM.

Some of the above requires an unlocked bootloader, of course.
