Your not the first to do this, coming from owning a Mediatek device/phone, it makes sense as that's exactly the same way the recovery works on those phones. ?
i did everything but...
I installed the MSMdownload to my 3t, removed it from my pc and booted it but for some reason it wont boot or connect to my PC anymore. can you please help. thanks
Windows guide, might work for other aswell.
I finally solved my problem with my Lenovo Y700 tablet being stuck in bootloop mode due to trying to flash Magisk boot with a mismatched firmware version. This resulted in the UI constantly crashing, and I could not connect to Wi-Fi, and other problems...
I tried flashing back to stock with QFIL, which put the device in a bootloop. I will explain why later on.
I also lost recovery mode due to trying to solve the problem, and now I was stuck with either showing the bootloader screen, or restarting the tablet, which brought me back to the bootloader.
So the tablet was now genuinely useless. This is what I did to bring back the stock ROM and later flash to crDroid 8.10.
Flashing boot.img, system.img or recovery.img was no luck.
First off, there is no need to have unlocked "USB debugging" before your tablet bricked.
Second, you don't need to have your "sn.img" file from Lenovo, you can unlock the bootloader using fastboot commands.
Fastboot commands works on the bootloader screen, without having ADB connection.
Start by downloading these four files:
Platform tools r33.0.2
QPST_2.7.496
Qualcomm_USB_Driver_v1.0
Lenovo Y700 tablet stock ROM
We'll start by unlocking your bootloader. You can do this from the bootloader screen. If you for some reason can enter recovery mode, enter fastboot.
1. Connect your tablet to your PC.
2. Open a terminal windows in the ADB folder. On Windows 11 this can be done by right-clicking inside the ADB folder and select "Open in terminal". If you don't have that option, try Shift + Right-click. If that doesn't work, you can always start the terminal by pressing Win + R, and type in "cmd" without citations. Now you have to navigate to your ADB folder by typing
Code:
cd (here you'll type in the location of your ADB folder)
Without the brackets.
3. When located, type in
Code:
fastboot devices
You should see your tablet in the list.
If not, try using another cable or USB port on your PC.
4. Now type in
Code:
fastboot oem unlock-go
Restart your tablet, and it should now say "unlocked" under "DEVICE STATE" in the bootloader.
5. Now you can start by installing the programs on your PC, QTPS, Qualcomm driver and platform tools.
6. Extract ALL files from your stock ROM to the "bin" folder in QTPS location (usually C:\Program Files (x86)\Qualcomm\QPST).
This will help with Sahara errors in QFIL.
7. Open QFIL from your QTPS bin folder, it installs with QTPS. Don't worry if it shows "No Port Available", we'll get to that. Your configuration should look like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Your main window should look like this:
Don't worry about the "status" window.
Hit "browse" in the "Programmer Path" window, and navigate to your QTPS bin folder. Select "prog_firehose_ddr.elf"
Hit "Load XML", and navigate to your QTPS bin folder. Now, select ALL of the "rawprogram" files (my first mistake, I only selected the "rawprogram_unsparse0.xml" file on first flash)
In the next window, select ALL of the "patch" files (my second mistake, I only selected the "patch0.xml file" on first flash).
Without doing this, you will only flash a portion of the ROM, and not all of the partitions needed.
8. Now it's time to reboot you tablet into EDL mode to be able to flash. Start your tablet by pressing VolUp + Power button.
If you can't turn off your tablet when connected to PC, just select "Power off", and just hold the VolUp button as soon as the device vibrates and reboots, keep holding until the screen flickers and turns off.
9. Now QFIL should detect the Qualcomm 9008 port. If not, hit "Select Port" and select the Qualcomm 9008 port.
10. Hit the now available "Download" button, and the flashing should begin. Allow it to run its course, and it should reboot the tablet when done. Might take a while.
If flashing won't start properly, you might have waited too long between entering EDL mode and hitting the "Download" button.
If so, disconnect your device, which might now be "dead".
Don't worry, you can fix this be holding VolUp + VolDown + Power button for a long time, say about a minute to be sure. Release the Volume keys some second before releasing the Power button.
Hit the power button again, and the tablet should boot to bootloader screen again.
Repeat the steps to enter EDL mode, and now hit the "Download" button in QFIL when it becomes available, don't wait too long.
You're done! I recommend opening "Settings", enable "Developer" option, by pressing the "Build number" on the "About tablet" screen repeatedly until a pop-up appears saying "You are now a developer".
Open "Developer options" and hit "Enable USB debugging", it will allow you to run ADB commands from your platform tools folder.
If you want, you can again open the terminal in the platform tools folder and type
Code:
adb devices
It should now show your device in the list.
Now you can uncheck the "OEM unlocking" in the "Developer options" which should let you get OTA updates when available.
There are plenty of guides on how to flash different GSI's like crDroid, so I won't cover that here.
Enjoy your tablet!
For whatever reason, my devices isn't showing up when writing "fastboot devices" but shows up in QFIL. Any suggestions?

I got one with the "GLOBAL ROM" which miss a lot of feature so I follow this tutorial to flash the stock rom and works like a charm.
The only question is why I can't get any OTA?
Due to te unlocked bootloader?
I tried to relock it but when it's done it say "device corrupted" on bootup so I had to unlock again and reflash all again.

Yes, this one is weird. Some people are able to lock it, and some are not.
To my understanding you need to lock it to get OTA's. It's still possible to update, though, through downloading the newer update and installing the update in .zip format on stock ROM.
Is possible to find the update package? I find 2 in the other y700 thread but they are incremental from an above version of mine and won’t install
Also searched a day on Chinese forum but no succes…
Which version do you have installed?

hi, in my case after fresh flash to zui 13 official i can use ota to zui 14 even the tablet in unlocked state, someone in xiaoxin pad pro thread suggested using vpn 'returness' set to china (shanghai 11) i think... and ota did works, zui 14 is about 3 half gig so i ended up using link from y700 thread to install manually
Just for anyone else having trouble getting into EDL mode (my Y700 wasn't bricked, I just wanted to restore stock rom):
When the tablet is running normally, go to developer options, enable USB debugging, then go to the platform-tools folder on your PC and open a command prompt there, then type "adb reboot edl". Then you'll see the "Qualcomm HS-USB QDloader 9008 (COMxx)" Port under Ports in Device Manager.
To re-lock, I believe you can use these instructions. The command "fastboot flashing lock" brought up the menu on the Y700 screen to re-lock, but I didn't do it because I didn't want to delete my user data (I'd just spent time setting up all my apps!)
When I was in fastboot, the tablet was showing up with an exclamation point and just called, "Android device" in Device manager, I used the drivers from here to get it to show up as "Android Bootloader Interface".
Don't do what I just wrote!! I did it and now I'm stuck and it won't boot, and I can't get to EDL mode.
I don't have time to work on it now but my tablet is effectively bricked.
I'm in a bootloop to the fastboot screen, and it shows up in Device Manager as "Android Bootloader Interface". I can't flash in QFIL as described above because it just says "No Port Available". I can't get to EDL mode as I did before because I can't boot the tablet as usual to enter the "adb reboot edl" command.
"adb devices" doesn't show the Y700.
Can anyone tell me how to get to EDL mode when I can't get adb to work?

That's what happened to me! How did you get it back into EDL mode after unlocking?
Mine isn't showing the Qualcomm device under Ports in Device Manager anymore, so I can't get the port to show in QFIL!!
Got it to work getting to EDL mode, phew!
If you can't turn off your tablet when connected to PC, just select "Power off", and just hold the VolUp button as soon as the device vibrates and reboots, keep holding until the screen flickers and turns off.

This got the Qualcomm port to show up again.
So I'm now running the stock rom but still unlocked so no OTA. What a waste of time that was.
Hoping someone can work out how to re-lock.

you have to use Chinese vpn, it’s not because of unlocked booloader, I will link you the one I used later, btw no need to relock bootloader, for getting ota

Haha, maybe I should read more of the comments before assuming things.
Hic, I just got a second hand Y700, it had an original Zui 13 chinese rom, and I started to OTA update upto ZUI 14. Then the Google Play disappeared, also the PC mode. I tried to downgrade to ZUI 13 with this guide WITHOUT enabling usb debugging nor oem unlock. The flashing process succeeded, but when the tablet reboots, it shows for the first time "Your device is corrupt, It can't be trusted and will not boot", after that keeps showing bootloader menu.
Please help me what to do from this step?
I'm in a different state from others here, I think; my Y700 appears to be totally bricked. It's plugged in to charge and nothing's happening at all. I originally installed crDroid on it, but ran into Widevine issues and was going to revert. I don't remember the last steps I took on it (it was a month or so ago), but when I picked it up again a few days ago, turning it on showed only a black screen (only detectable by seeing the backlight), so I let it discharge the battery entirely planning to try and fix it via reflash later. Now, however, it's doing... nothing.
I'm going to let it charge overnight and see if that changes anything, but if anybody has ideas what might have happened or things to try to get out of this, I'd appreciate it!
Hi, I'm stuck after flashing the Chinese stock rom on my legion y700. I was first successful except for upgrades which were proposed and installed but wouldn't show after reboot. I decided to flash again hoping that would solve the problem. But now my tablet remains in EDM mode and won't start. The final message in Qfil was 'download successful'. It is fully charged
Any idea on how to solve this issue?
I am in yet another state. I only run Linux (Mint 21), and have not been able to get any version of wine working, so I cannot use QPST or QFIL (windows .exe's). I CAN access my Y700 via adb or fastboot, and it is now unlocked. It was unsealed when it arrived, but does NOT have any google stuff on it.
I have downloaded all of the components needed from apkmirror, and followed instructions in the Y700 topic to activate them, to no avail.
Sadly, since I do not read Chinese, and the use requirement needs google, it might as well be a brick.
Further, despite more than 40 years doing technical support on all sorts of computers, I have never yet flashed an android device. Can it be done from adb or fastboot? If so, how do I specify which partition to flash? Does anyone have a guide to help me get started? I wish to put cdroid on it, do I use the .xz file or extract the .img?
OK, I've just found something I missed, but it doesn't work for me. My terminal is in the same folder as the .img
fastboot flash boot crDroid-8.10-arm64_bgN-Unofficial.img
Sending sparse 'boot_b' 1/15 (262088 KB) OKAY [ 8.186s]
Writing 'boot_b' FAILED (remote: 'Value too large for defined data type')
fastboot: error: Command failed
What am I missing (apart from a brain!) is this the correct partition to write crDroid to? is there an option to set the data type size? if so what?

Windows guide, might work for other aswell.
I finally solved my problem with my Lenovo Y700 tablet being stuck in bootloop mode due to trying to flash Magisk boot with a mismatched firmware version. This resulted in the UI constantly crashing, and I could not connect to Wi-Fi, and other problems...
I tried flashing back to stock with QFIL, which put the device in a bootloop. I will explain why later on.
I also lost recovery mode due to trying to solve the problem, and now I was stuck with either showing the bootloader screen, or restarting the tablet, which brought me back to the bootloader.
So the tablet was now genuinely useless. This is what I did to bring back the stock ROM and later flash to crDroid 8.10.
Flashing boot.img, system.img or recovery.img was no luck.
First off, there is no need to have unlocked "USB debugging" before your tablet bricked.
Second, you don't need to have your "sn.img" file from Lenovo, you can unlock the bootloader using fastboot commands.
Fastboot commands works on the bootloader screen, without having ADB connection.
Start by downloading these four files:
Platform tools r33.0.2
QPST_2.7.496
Qualcomm_USB_Driver_v1.0
Lenovo Y700 tablet stock ROM
We'll start by unlocking your bootloader. You can do this from the bootloader screen. If you for some reason can enter recovery mode, enter fastboot.
1. Connect your tablet to your PC.
2. Open a terminal windows in the ADB folder. On Windows 11 this can be done by right-clicking inside the ADB folder and select "Open in terminal". If you don't have that option, try Shift + Right-click. If that doesn't work, you can always start the terminal by pressing Win + R, and type in "cmd" without citations. Now you have to navigate to your ADB folder by typing
Code:
cd (here you'll type in the location of your ADB folder)
Without the brackets.
3. When located, type in
Code:
fastboot devices
You should see your tablet in the list.
If not, try using another cable or USB port on your PC.
4. Now type in
Code:
fastboot oem unlock-go
Restart your tablet, and it should now say "unlocked" under "DEVICE STATE" in the bootloader.
5. Now you can start by installing the programs on your PC, QTPS, Qualcomm driver and platform tools.
6. Extract ALL files from your stock ROM to the "bin" folder in QTPS location (usually C:\Program Files (x86)\Qualcomm\QPST).
This will help with Sahara errors in QFIL.
7. Open QFIL from your QTPS bin folder, it installs with QTPS. Don't worry if it shows "No Port Available", we'll get to that. Your configuration should look like this:
View attachment 5741653
Your main window should look like this:
View attachment 5741651
Don't worry about the "status" window.
Hit "browse" in the "Programmer Path" window, and navigate to your QTPS bin folder. Select "prog_firehose_ddr.elf"
Hit "Load XML", and navigate to your QTPS bin folder. Now, select ALL of the "rawprogram" files (my first mistake, I only selected the "rawprogram_unsparse0.xml" file on first flash)
In the next window, select ALL of the "patch" files (my second mistake, I only selected the "patch0.xml file" on first flash).
Without doing this, you will only flash a portion of the ROM, and not all of the partitions needed.
8. Now it's time to reboot you tablet into EDL mode to be able to flash. Start your tablet by pressing VolUp + Power button.
If you can't turn off your tablet when connected to PC, just select "Power off", and just hold the VolUp button as soon as the device vibrates and reboots, keep holding until the screen flickers and turns off.
9. Now QFIL should detect the Qualcomm 9008 port. If not, hit "Select Port" and select the Qualcomm 9008 port.
10. Hit the now available "Download" button, and the flashing should begin. Allow it to run its course, and it should reboot the tablet when done. Might take a while.
If flashing won't start properly, you might have waited too long between entering EDL mode and hitting the "Download" button.
If so, disconnect your device, which might now be "dead".
Don't worry, you can fix this be holding VolUp + VolDown + Power button for a long time, say about a minute to be sure. Release the Volume keys some second before releasing the Power button.
Hit the power button again, and the tablet should boot to bootloader screen again.
Repeat the steps to enter EDL mode, and now hit the "Download" button in QFIL when it becomes available, don't wait too long.
You're done! I recommend opening "Settings", enable "Developer" option, by pressing the "Build number" on the "About tablet" screen repeatedly until a pop-up appears saying "You are now a developer".
Open "Developer options" and hit "Enable USB debugging", it will allow you to run ADB commands from your platform tools folder.
If you want, you can again open the terminal in the platform tools folder and type
Code:
adb devices
It should now show your device in the list.
Now you can uncheck the "OEM unlocking" in the "Developer options" which should let you get OTA updates when available.
There are plenty of guides on how to flash different GSI's like crDroid, so I won't cover that here.
Enjoy your tablet!

A lot of this does not seem to work on Linux (Mint 20.3).
fastboot flashing unlock
worked for me, and while I have no problem getting into recovery or fastboot modes on my Y700, I never see anything I recognize as EDL. On a machine with 'wine' installed and working, QTSP installs and appears to run OK, as also does QFIL. I can select the "rawprogram" and "patch" files OK, but it cannot find a port.
Both adb devices and fastboot devices report the correct device when it is in the appropriate mode, and
fastboot flash system crDroid-8.10-arm64_bgN-Unofficial.img appears to have successfully flashed correctly, but it is still unable to communicate with Google servers. All good (tear hair out type) fun!
