[JonTrv]

Remember that I (exclusively) run Linux (Mint 20.3 & 21.1), so could not use QFIL or QPST.
I unbricked my Y700 using a Linux tool (QDL) that provides access to the Qualcomm EDL port 9008. This post describes how I used it to restore the stock ROM.
As you point out, I too discovered that the Y700 has two modes that respond to fastboot commands from ADB. Only the fastbootd mode allows flashing the system partition(s). My device is now happily running crDroid.

Does Pen functionality work in crDroid?

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.

Hey fiera, I have a question. I've read all the threads on here regarding the y700. Why does everyone recommend nazim's fork of crdroid?? I have his crdroid 8.9 which runs good but android security patch is Sept 22. Ota updates don't seem to work either. I don't necessarily want to flash a new ROM every time he updates for a security patch and due to my work I really should be staying up to date on all my connected devices. Because of this Im thinking about using the official crdroid gsi and got me very curious why everyone goes to Nazim's build.

Thanks much

edit: I see now that official crdroid isn't a gsi and doesn't support our device.
Nazim's ancientOS seems to be "official" though. Do you happen to know what the main differences between the two roms are? Do OTA updates work on his ancientOS?

Are you on Nazim's crdroid or crdroid official?? Im on Nazim's, wondering if official crdroid works okay, I'd love to have OTA updates

 

[JonTrv]

My installed version is "crDroid-9.1-arm64_bgN-Unofficial". I got it from here, which appears to be a Nazim version, and possibly the latest available. Certainly I have not found anything newer on a recent search - I will keep on searching
OTA updates? Unlikely from what appears to be almost a one-man project. Remember though, Nazim is standing on the shoulders of giants. crDroid is a based on LineageOS, which in turn is based on AOSP. My installed 9.1 works out-of-the-box except for two details. I do not get sensor controlled screen rotation and I do not get stats on battery usage. So far I have not done enough research to find out why for either issue.

Thanks for the reply! That does seem to be the newest version. I looked into other GSIs (found this nice long list from magisk here ) like ancientOS, but crDroid does seem to stay the most up-to-date and like you said it just works great out of the box. I guess I just need to use titanium or nandroid or whatever to backup apps and such, and flash a newer version whenever its updated with security patches as that is my main concern. And, for being one man, Nazim is pretty fast at rolling updates out too, especially considering It seems like he's now working on quite a few different gsi roms

I'm currently running Nazim's crDroid 8.9 and both my auto rotation and battery stats work. The only problem I've run into so far, is I can't get audio via HDMI. Whether using a USB hub or a plain USB-c to HDMI, it plays video on the TV and audio on the tablet. Im probably going to update to Nazim's crdroid 8.10 or 8.13, as that has more recent security patches and If I'm lucky the HDMI audio will work. I'll stay away from 9.x until auto rotate is fixed.

Thanks again!

Nazim's ancientOS seems to be "official" though. Do you happen to know what the main differences between the two roms are? Do OTA updates work on his ancientOS?

Mr.Nazim is recognized by the official Ancient development team as an official maintainer, so Ancient OS is official GSI.
Therefore, that GSI will become "official" if he wants it and applies for crDroid official status.
You can also update crDroid without OTA by overwriting the system from the fastbooted menu (e.g. from 8.10 to 8.13).
Of course, you can update to 9.0 or later without any problem, but as mentioned above, there are some problems with the ROM itself, so it is not recommended (e.g. face unlock doesn't work).

 

[seeayesix]

Apart from the face unlock not working and the app drawer being wrongly configured (which is fixable) I think Nazim's CrDroid is really good. I just dirty-flashed it from 9.2 to 9.3 (no OTA updates).

I have not recognized any problems with auto-rotation not working?

Hello to everyone! I've been trying to install MrNazim GSI crDroid-8.5-arm64_bgN-vndklite-Unofficial.img on my Y700. I've encountered several issues, which I couldn't resolve by myself, so I'm reaching out for your help.
Here's what I want to achieve: working stylus (Lenovo Precision Pen 2), Magisk, magnet cover support and so on.
Here's what I've done: latest update of zui 13 -> flashed vendor from zui 14.0.197 for stylus support -> flashed vbmeta from zui 14.0.197 so that it could boot properly -> flashed system from the GSI -> factory reset -> booted. System's first setup shows up, wifi, e.t.c. BUT I can't finish the setup because facial recognition doesn't work. I've encountered this issue when I flashed the GSI's system.img over latest ZUI 14, and over ZUI 13 with ZUI 14's vendor.img. What am I doing wrong? Thx in advance!

Do the lockscreen and homescreen both auto-rotate? It didn't work for me on 9.1, I haven't tried 9.2 or 9.3 though

 

[seeayesix]

Haven't checked, but I will. I never use autorotate on lock or home screen actually

Thanks, I'd really appreciate that. I didn't think I'd care about it but I use my tablet in landscape orientation quiet a lot and got frustrated having to do my login pattern 90° counter clockwise. A small thing, but still a thing.

I can't offer you a lot of help other than to say you should try 8.10, facial recognition works fine. I did try 8.13 and couldn't finish setup due to the facial recognition issue. I'm not very knowledgeable about the technical stuff, so I can't tell you why you're having the issue. But yeah, 8.10 works fine with facial recognition and setup could complete.

It works on my tablet actually, both homescreen and lockscreen auto-rotate but I had to do a bit of digging to find the settings.
I'm running crDroid-9.3-arm64_bgN-slim-Unofficial.img.xz which I just dirty-flashed on top of the 9.2 slim. It's still a struggle to skip face unlock and get the app drawer to scale correctly on the screen if you set it up from scratch.

 

[JonTrv]

I can't finish the setup because facial recognition doesn't work.

I failed to record the exact command, but when you are going through setup before you get to face unlock, your device will respond to ADB commands from your PC, I did something like:

adb shell uninstall faceunlock

(please research adb shell commands for the correct syntax, and there is an adb shell command to list installed apps, so use that to find the correct name.

 

[JonTrv]

Neither work on mine, also 9.1. I have a workaround. I use an app from the play store,
'Rotation Control' (developer listed as 'CrapeMyrtle').
I find it the least instrusive of all the similar function apps in the store. Granted, I too, do not often change screen orientation, but this helps when the need is there.

I actually saved your comment from a while ago regarding how to uninstall faceunlock. The command was

adb shell pm uninstall --user 0 com.crdroid.faceunlock

I tried to use it when I was struggling with the faceunlock problem while setting up 8.13. Strangely my y700 wouldn't respond to adb commands after installing 8.13, but it did work when I installed a different version (maybe 8.5, I don't recall now). So I'm not sure if adb debugging was disabled by default, but because I couldn't finish setup I couldn't get into the settings to turn it on.

Thanks for this, and also your previous reply. Any help is always appreciated! Does the app just have a button to select portrait/landscape or does it actually allow autorotation to function autonomously?
Thanks again for the suggestion.

 

[JonTrv]

Does the app just have a button to select portrait/landscape

Button, yes, at least the way I have it setup. Autorotation no.

Well done, I forgot that I had recorded it on this forum.

I would have thought USB debugging would have to be still enabled from before the GSI flash, however, hopefully you have got the faceunlock bypassed by now. I never tried 8.13, the first GSI I got to flash without error was 9.1. A steep learning curve dealing with this device, shame I cannot use the learning to update my old Acer K7, still running abandonware!.

I don't understand how the flashing process works, I'm a follow someone else's guide kinda guy haha. But yeah, adb didn't even detect the device after I flashed 8.13, so I was out of luck when trying your face unlock solution. I'm tempted to install 9.1 again and then dirty flash 9.3, though I'm not 100% sure that's a smart move. It's a lot of hassle to go back to 8.10 and reinstall everything if I end up with an issue.
