OK. here's a installing process.

①Unlock bootloader with SN.img. This procedure is the same as for other Lenovo tablets such as the Xiaoxin Pad, so I'll skip this step.
②Put the tablet in Fastboote"d" mode. I usually enter this mode by pressing and holding the volume down and the power button to activate fastboot mode, then selecting "Enter Fastboot" from the recovery menu.
③You have to download the arm64 version from the CrDroid GSI link that the text my first post in this thread. I recommend arm64-BgN-vndklite.
④I will assume that you have already configured Android Studio. Start a command prompt and type the command fastboot flash system (the img file you downloaded and unzipped) You can also do this by dragging and dropping the img file into the window before flashing system.
⑤Operate the tablet; proceed to Enter recovery→Wipe data/factory reset to initialize the tablet's data. Otherwise, it will freeze at the title.
⑥Reboot system now and after a while CrDroid will start.

If you have any stumbling blocks, please ask me again.
So i'm keep getting the error that i can't load the img. Not sure if me getting the "Global" Rom and flashing it back to the chinese one has anything to do with it. I'm in Fastbootd mode so not sure what else to do.

There isn't one, because IMEI is only for things with cell phone connectivity.

I assume you are asking because of the official Lenovo unlock - if you translate the page there is a separate link for tablets.

I'm pleased to report that I have tested a ROM that I had not tried before and have confirmed that it meets all of my requirements.
The Nazim's crDroid GSI is the best ROM for the Legion Y700 (I didn't like the logo, so I didn't use it until now).
Below is a list of the outstanding features of this ROM.

・It doesn't have a fixed lock screen in portrait orientation like Corvus or Descendant.
・It doesn't contain superfluous and undeletable files like "su" like Lineage.
・It includes face unlock unlike ArrowOS (by the way, crDroid and ArrowOS are built by the same person, I wonder why he didn't include face unlock in the latter).
・It doesn't cause any noticeable glitches like ProtonAOSP or Pixel Experience (it still runs the Alpha version of the Lawnchair Magisk Module without crashing).
・This ROM is so customizable that you don't even need the Magisk or LSPosed module that you have been using. The status bar can be customized, and even the volume step can be adjusted.
・The default wallpaper of this ROM is very beautiful (my personal opinion 😅).
・It can pass SafetyNet. most other 12L GSIs could not do this.

Of course, this ROM alone is still not enough in some areas, but I think that can be improved with the App placed by Mr. @NisseGurra and the modules in this link
(Click the "Magiskモジュールのダウンロード" button to jump to Google Drive and download it). This module enables automatic brightness change of the screen, and also allows assignment to the right switch (originally the game mode activation switch) using the Button Mapper.

I hope all Y700 users will use this ROM. Thank you.
How to flash this rom? Can you give me link rom? Please

Hello, I am planning to buy this tablet but I have a few questions.

1 - if I buy a global rom, will I be able to do root immediately, or will I have to upload the original Chinese soft first?



2 - after uploading this cdroid 8.5,
I will have the Polish language and I will not have any bushes? could someone check it for me? having a swiftkey keyboard, and writing in Polish (pl) will it underline the text in red or not?

Hello already with the tablet, I have a Global Rom in, version as in, photo. I also found the same soft with exactly the same version number + info user Open-TB-9707F_CN_OPEN_USER_Q00235.1_R_ZUI_13.0.586_ST_220222_qpst (ie would be unlocked as Global?). Is there an option that I can have twrp on it to make a backup of the system before I start uploading a custom room?

It would be useful to have a full tutorial from a to z on how to do root, twrp etc on this tablet having a Global Rom / Chinese so ft

    Hi Y700 owners, of future owners :)

    So to have a dedicated forum for the Y700, we need to open threads in other "remotely related forums" and have some interesting discussions.
    Therefore opening this one as an attempt to get a little more organized Y700 posts and, especially, to get visibility and get our own forum :)

    I'm not too much familar in 2022 with ROMs and other stuff (i was playing with those things a few years back and a lot has changed since), but i understand there are some GSI (generic system image) ROMs that are available, from what i understand, for several devices that don't have a dedicated ROM. That is something new to me i have to say.

    @FIERA03 , i hope you don't mind me quoting you here, but as you have done some interesting testing, to give it more visibility, i'll paste your results here from another thread.

    I 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...Lock screen does not rotate. Probably because it is based on Google Pixel ROM. Corvus also does not have face unlock.
    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.

    Thanks a lot @FIERA03 for these information. Very valuable for anyone interested in flashing its Y700.
    This was your status on May 22nd.

    Of course you need to unlock the bootloader, which you can do after entering IMEI and email at this website: https://www.zui.com/iunlock (Thanks for @NisseGurra for posting this link in another thread).

    Are there any other interesting experience that anyone can share with either those GSI or other images?

    Thanks a lot for your contributions to have some kind of Lenovo Legion Y700 community started ;)

    For the GSI Y700 users, there is an treble app update from phh (attached). It enable magnetic cases wake and close screen.

    Its been a few months since you made this post, thank you!

    I was wondering if you have any updates on this. Is this still your recommended Rom?

    If not, which one are you running now?

    I noticed the developer of crdroid has a lot bunch of newer builds available, have you tried those?

    Thanks for your input keeping this device alive :D
    I've also tested several Android 13 ROMs, and none of them seem to be optimized for tablets yet (at 1st I found a severe bug in the standard launcher).
    Therefore, I still consider crDroid GSI's 8.13 to be the most suitable ROM for this device. The next best is Mr. AndyYan's LineageOS (Secure), which is easy to use.

    @FIERA03 can you provide an instruction "how to install crDroid to Y700"?
    OK. here's a installing process.
