Thanks to Mickey36736 I managed to perform the update to zui 14.0.231 very easily.
A total life-saver because zui 14.0.197 has the frame drop problem. Which is so bad you almost don't wanna play your game anymore.
After 1 week of emailing lenovo China they tell you they only help mainland people. They tell you to contact the seller. The seller who is not responsable. In this case giztop. And listen giztop is an awesome company. I asked giztop if they would agree to accept back the tablet and make a refund. Because i wanted to order a new tablet and send the y700 with the update problem back to giztop. Thet agreed. Even though they are not responsable for this update problem. So giztop is just an awesome company.
zui company is responsable. They only react like this. Thank you for your feedback. Good luck. They don't care about anyone who lives outside China. They give you the big middle finger.
anyhow big thanks to Mickey here. Later guys!

They did mentioned about fixing GPU problem on .231 but there is an issue with legion assistant .
When you switch power profile to power saving mode and then back to balance mode, the GPU and CPU clock speed remain the same as power saving mode which is annoying so you have to minimize the game and go back in to fix the issue. Which might explain why the performance is different
Okay nice to know. Because the frame drop problem is not solved on ZUI 14.0.231. I justed started the game and the frame drops still occur.
ZUI developers totally messed up. ZUI 13 was working very smooth. Developers made some kind of new gaming software for ZUI 14 and it's only causing frame drops.
Total failure
LoL

Legion zone has an auto clean mode switched on. Standard set on 50mb. So this process will start every time. You should disable this feature.
In the pictures you can see where it's hidden.

Hi everyone. I'd like to buy the Legion Y700 and I plan on installing a custom ROM (I heard crDroid GSI is pretty good) but it's been ages since I last did anything like that and I haven't kept up with the practice at all.
Given that info, does it matter if the tablet that has had its firmware modified before shipping ? I'll have to format it anyway, right? I just want to make sure.
Also, why isn't there a dedicated Y700 forum ? Trying to find info about this device is a nightmare.
Thanks

No, if you are definitely going to install a custom ROM, it doesn't really matter. I will say I am reasonably happy with ZUI 14, though I liked 13 better.
As to why there isn't a forum, I have no idea! This thread is getting huge.

I like ZUI 14 a lot. First thing after purchasing new device is to install custom rom, always. But ZUI 14 is brilliant, so i dont feel a need to do so.
It isn't bad, hopefully the fix the pulldown for notifications on the next release. It is ridiculously narrow in landscape mode.

the zui is just crippled, always kills all my background apps... but i loss the srgb mode in any gsi rom, the default dcip3 color space on the gsi roms always oversaturate everything... how can i get srgb color space to work on gsi roms?? even srgb mode without factory calibration is enough...
If I would live 4 weeks ago I'd buy the y700 again. Before connecting to WiFi disabling zui update tool. Enjoy zui 13 for the rest of my life. And beyond lol
Zui 13 has a perfect gaming assistant. No clue why one would install a Custom ROM. This is... A gaming tablet.
Zui 14 is not acceptable and actually raped my device. I played a game named shadowgun legends, not a very heavy game. Still zui 14 ****s up the game with frame drops so extremely I actually stopped playing on this tablet.
People who enjoyed zui 13 and also actually played a game on this device know zui 14 totally messed up this tablet. If you find zui 14 to be acceptable try a heavier game. You can't play it without the drops. On zui 13 you could play this same game and it would run like a Tesla 2024 moonmissile.
Would I advice to buy this tablet. O yes. But use it for gaming an use zui 13. Why use this gaming tablet for custom roms and ****e? Zui 13 and the y700 is a very effective combination.
Anyway later.

If you know a way to easily do this. I'll be happy to hear it my friend.
You mean downgrading?

6Okay. I have managed to do everything from combined insights. So, let me save you guys the trouble I had by writing my proces down (and for myself for the future).
I came from the 'global rom'. And wanted to end with 13.1.578 ROOTED
1. Download this file. It contains the stock firmware on 13.0.586. Unzip it, and find the recovery.img as we need it later.
2. Upgrade all the way you like through OTA.
3. Flash TWRP from here. Know that it is a 'faulty' version with only a line on top of the screen. And this vbmeta file. Place both files in your ADB folder.
4. Use ADB to extact the boot.img from the version you are on.
4.1 Boot into the bootloader (adb reboot bootloader).
4.2 disable AVB (not sure this is necessary, but it worked for me) by sending the following commands:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot erase userdata
4.3 Instal TWRP by sending this command : fastboot flash recovery recovery.img (note that you use the name you gave your TWRP file)
4.4 reboot in recovery mode (fastboot reboot recovery/manually on the tablet)
Now the TWRP recovery should load, with only a line on top, and nothing else.
4.5 In the TWRP recovery enter: adb shell (you should see a # appearing in the line)
4.6 Send these commands out:
dd if=/dev/block/bootdevice/by-name/boot of=/sdcard/boot.img
adb pull /sdcard/boot.img stock_boot.img
what this does, is extracting the boot.img of that specific version you are running, and placing a copy of it into your adb folder.
4.7 send these commands to get back to the bootloader:
twrp reboot bootloader
5. Flash back the stock recovery. If you followed the guide, you have the stock recovery from step 1. Give it a fancy name, and place that file in your adb folder and sending this command:
fastboot flash recovery yourfancyname.img
fastboot reboot
Now it may give some warnings and errors. It told me to do a factory wipe, wich was okay for me. After that the tablet starts normally. Stock firmware, but still on the same version I wanted.
6. Now the easy part starts. The stock_boot.img you got in step 4.6, should be on your pc. After the inital setup on the tab, place that in your root folder. Download Magisk and install it on your tablet. When it is installed, click on 'install' and 'select and patch a file'. Select the stock_boot.img you moved to the root of your tablet. The patched file will be in your download folder. Transfer that patched file to your adb folder on the computer.
7. Go into adb and boot the tablet into recovery mode (this should be the stock recovery again): adb reboot recovery.
8. In recovery mode, go to fastboot. It'll say fastbootd on top.
9. Enter this command: fastboot flash boot patched-file-of-magisk.img
10. Restart the tablet. Congrats, you now have rooted your desired version.
It might be to much info, but I wish I had these steps. It was late yesterday. Very late...So to save you the troubles, I present you my humble guide. If you have improvements in the steps or instructions, please let me know!!4Use this apk to switch between modes

Chinese ROM because there is no actual global ROM and your really don't want some reseller installing some random crap, you can just do that yourself when you get it. You can easily switch to english and install Google Play store on chinese ROM.
Annoyance because the notification pulldown is a bit janky and notifications don't always seem to show up like I would expect. Plus every once in a while there will be something in Chinese you need to translate with another phone or take a snapshot and send to Google translate to see what it is telling you (aka new version released etc).
Even with the above it is a super nice piece of hardware. I would love a real global ROM, but at the same time I am totally happy with the device.2
Haven't heard a peep about a new one, and honestly it is the ONLY 8 inch Android tablet in it's class right now, so not much choice.
The hardware is superb. I do wish there were a real global ROM, but I am fairly happy with Zui 14. -
11Bricked Lenovo Y700? Follow this guide.
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 typingWithout the brackets.Code:cd (here you'll type in the location of your ADB folder)
3. When located, type inYou should see your tablet in the list.Code:fastboot devices
If not, try using another cable or USB port on your PC.
4. Now type inRestart your tablet, and it should now say "unlocked" under "DEVICE STATE" in the bootloader.Code:fastboot oem unlock-go
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:
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 typeIt should now show your device in the list.Code:adb devices
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!8Hi all.
I just got this tablet yesterday.
Language available on tablet are chinese and english maybe (morelocale2 could be useful)
Google play services can be download directly from ZUI app store inside the tablet.

not sure about root or unlock bootloader (didn't use android device for a long time)6Okay. I have managed to do everything from combined insights. So, let me save you guys the trouble I had by writing my proces down (and for myself for the future).

It might be to much info, but I wish I had these steps. It was late yesterday. Very late...So to save you the troubles, I present you my humble guide. If you have improvements in the steps or instructions, please let me know!!5I have flashed a lot of GSI on this tablet so far.
Here is a summary of the bugs and other issues that I have noticed in them.
※All of them are Android 12L except for the ones without special notes.
①Corvus OS, Descendant OS, Cherish OS...Lock screen does not rotate. Probably because it is based on Google Pixel ROM.Corvus also does not have face unlock.The latest Corvus also added this.
②Ancient OS(Android 12.0)...Lock screen does not turn to landscape. Also, when I change the username or photo at the top of the settings, the settings app crashes. Also note that the settings app crashes if you change the username or photo above the settings.
③Proton AOSP...When I restarted to set up Magisk, the settings app repeatedly stops. Deleting app data and cache had no effect.
④Havoc OS(Android 11)...The startup logo does not appear in the first place and comes back to the bootloader.
⑤Superior OS...It started, but the FPS dropped extremely. I judged that it is difficult to use regularly.
⑥Pixel Experience…The screen is still not landscape. Also, it seems that it is not optimized for tablets any more than Descendant, and when I call the dock while launching an app(the feature of 12L), the icon looks like it has been split in half.
⑦All of NipponGSI...Like Havoc OS, it comes back to the bootloader. It may be a bad compatibility.
⑧Lineage OS…There was a switch "Rotate lock screen" in the settings. But I don't use it, because the "su" binary is still in the root file and can't delete it ,so interferes with SafetyNet.
⑨Arrow OS...This also allows the lock screen to be turned landscape and is also very light. Although the lack of face unlock is a demerit (LSPosed module didn't work→https://forum.xda-developers.com/t/11-universalauth-face-unlock-for-all-roms.4419343/).But there are few complaints for me. So I'm using it regularly.
I'm sorry if it's hard to read because I'm not good at English. Thank you.5
Yep. The information is all in this thread.
If you tried looking yourself its pretty easy to find. No one here owes you anything.
That said - we need our own forum
