Hi everyone. I'm quite new to ROMs, etc.

I love the small form factor tablet - I have a Galaxy Tab S2 that is unfortunately getting a bit slow for my liking.

I'm thinking of getting a Y700 for Chrome/Firefox/Tor Browser, Gmail, Relay (Reddit app), and keepass2android/Syncthing. I'm not a gamer.

So, fairly basic usage but I would like notifications/120Hz/landscape mode to work properly.

I'm not really a fan of a Chinese ROM, I'd rather run an open ROM if that's possible, I can follow tech instructions, but I'd be really unhappy if I managed to brick it.

I was going to order from Aliexpress, I need it to be in English and I need Google Play Store - is "Global ROM" what I want? Any other gotchas?

So I came from a Tab S2 too, with a year of Tab A 8.4 in between (that thing had WAY too little internal storage). It is super annoying that the trend is away from flagship 8-9" models, to me they are a perfect size.

The Y700 is *really* nice. Honestly I didn't have any trouble making it act just like my Samsung devices:

  • Global ROM just means the Chinese ROM with English - it isn't that bad though, you can launch the Lenovo store thing immediately and install Google Play.
  • It is useful to have another phone with photo translate on for the 1st 1/2 hour for a few things.
  • I always install Nova Launcher - so did that and removed all the Chinese stuff from the launch menus
  • Turn off notifications for the Chinese play store and other apps, or use adb commands to totally disable (I did a bit of both)
  • In the security app, turn on things you want notifications for in the 'Autostart manager' - I turned on Google Play too

So far, it seems to me like notifications are working fine. But I don't use it like a phone, so not completely sure.

At any rate, after reading this whole thread and playing with it for a couple of days - my summary is I think you will be happy with it even without flashing a different ROM.

Personally I would avoid the global ROMs, some have mentioned problems updating when using them (though some as xnappo mentioned are just the original one set to English).

If you get one with stock ROM and unopened/unconfigured, when you turn it on and get the configuration screen on the top corner (can't remember if left or right but I think it was left) it says "English." Hit that and the rest is easy peasy (other than the built-in app store which is all in Chinese but you can type google play in English and it will find it). Do that and you might not even need a phone handy to photo translate.

So I updated my review to reflect the changes I´ve seen on ZUI14 but for those that don't want to check out that thread, here's the updated bit:

****ZUI14 UPDATE****

It works fine for the most part.

There are some changes:



STYLUS SUPPORT

the tablet now supports a stylus which explains why the underlying software supported external solutions like the Lenovo M14t portable monitor. Still, it begs the question "If the hardware supports a stylus, why didn't the earlier firmware support it out of the box?" Also important, AES (1.0 AND 2.0) only pens DON'T work, MPP only pens don't work either, which makes me think it requires strong WGP. I recommend only using a Lenovo pen which has been verified to work. The one I have personally tried is the Lenovo Precision Pen 2. I read elsewhere the Lenovo Active Pen 3 works but I can't personally attest to that.


DESKTOP MODE/MULTI-WINDOW

There have been some complains on forums of ZUI14 removing desktop mode. This isn't exactly true. If you connect to an external monitor with the tablet's USB-C port (using a USB-C capable monitor OR an HDMI adapter you can use desktop mode on an external monitor. However, you can no longer use desktop mode on the tablet itself. This was done on purpose and Lenovo, in exchange for this modification, added the ability to use multiple floating windows in the normal tablet mode. These windows are reziable but the default aspect ratio cannot be changed. Also having multiple windows open only works using the floating window swipe gesture (swipe up, hold and then swipe to the top of the screen). If you try to use the task switcher to make a window a floating window all other floating windows will disapper/be minimized). I personally think this is acceptable on the smaller Y700 but can understand how it could frustrate those using the larger P11 or P12.


LEGION APP


The original Legion app has been removed but all of its functionality has been added to the settings (there is now a "Legion assistant" section in the settings). Now rather than swiping down you swipe in from the left. The graphics are different but functionality is the same. Adding apps to the games list is easier since you get an app list and a switch on the side (similar to how you enable individual permissions in different settings). I read a comment elsewhere that the new software made the fps graphic stick on the screen. This isn't true. When you swipe the assistant off screen the fps can stick around but just for a bit and then they disappear.

Personally I think it is an upgrade worth downloading.

And for the record, none of this should be a surprise since Lenovo actually included it all in the release notes. (with less detail obviously).

Thanks for the replies. I see on the ad for one I want to order from Aliexpress (the cheapest :)), it says: "If you need the original sealed Tablet, which only support English and Chinese, NO GOOGLE PLAY, Please note on the order when placing the order!"

Is that true that Google Play won't work on the stock ROM?

Well, I've just caved and ordered the "original sealed tablet", so I guess I'll find out... :)

Yeah, basically if you don't ask for it sealed, they will boot it and install Google Play from the ZUI store for you. It is not hard to do though - like I said just have another phone out with camera translate on and you will be fine.

Hi folks
Do you think we will be able to install Windows 10 in the Y700 in the future?
I've seen other devices with the same processor that already run Windows 10 so that's why I'm asking
I'm pretty happy with the device but for productivity sometimes I find myself trying to do some things that Android just can't handle.

Doesn't help, no connection. I installed other from apkcure, not compatibile, cleared cache, reinstaled google services, deleted google account. Nothing helps, they don't want to work. Any idea? Maybe some other apk version, now it states that wrong version.

Thanks again to both of you.

They did have a little blurb saying that you would get a warning about bootloader unlocked every time you boot if they do it though, so I think they unlock the bootloader as well. The ad is here if you're interested.

I did see someone comment here - "Install google play from somewhere like apkmirror and not lenovo app store as previous purchases will not work on the lenovo installed version". So I think I'll do that instead.

Good idea?

Sounds like they would have done something more extreme than just installing Google Play for you, best off having them not touch it.

I installed Google Play from ZUI store and all my previous purchases worked, but there was a weird delay on some of them. Some showed up right away and others took a couple of hours to show up purchased.

I've made purchases on the tablet no problem using the google play from the lenovo app store on the original other Zui13 firmware.

If you upgrade to ZUI14 you will need to uninstall updates from google services and then install the android 12 version of google services (and the play store) from apkmirror

I know zui 14.0.222 is the latest but where would I check when something new pops up?. I know there is a zui14 website but it's all in chinese and even with browser translation its difficult to find anything on there.

    Okay. 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!!

    Why Chinese rom and why the annoyance? lol I'm US user so if I do, can I switch it to English?
    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.

    How did you manage to get pc mode back??
    Use this apk to switch between modes :D

    Hello guys, would u recommend getting this tablet now or should i wait for newer v2 or something releasing in 2023 (actually i dont know if there is any talk about new one or no), TIA
    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.

    after spending hours I finally has latest zui 13 with magisk root and gltools for force 120 fps in shadowgun legend but now I need to backup everything and I wanted to know if it was possible to backup whole zui 13 despite not having full twrp?

    I have swift backup but if I backup all apps +data with system apps, then let's say I flash stock rom on another y700 :

    will I be able to restore all apps systems apps and data and patched boot.img with magisk please?

    If no, what would be correct way to backup at least apps +data +magisk and patched boot. img please?
    without proper TWRP swift/titanium is the only backup we can get, restoring from swift is limited, i dont think you can restore system apps, so restoring magisk or anything else seems impossible

    Bricked 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 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:

    QFILconfpng.png


    Your main window should look like this:

    qfil.png


    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!

    Hi 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.
    Widevine L1.
    not sure about root or unlock bootloader (didn't use android device for a long time)
    5
    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, 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.

    If you tried looking yourself its pretty easy to find. No one here owes you anything.
    Yep. The information is all in this thread.

    That said - we need our own forum :D

    [EDIT]
    Okay @alex4723717 , here are some important posts:
