Try reflashing the recovery image via terminal
$su
#flash_image recovery /sdcard/recovery.img "assuming your recovery image is n root of sdcard and you renamed the recovery image as recovery.img"
#reboot recovery
See if that boots to recovery
How can you get to the terminal if the phone won't boot past the first screen?
camera+power goes to the first screen, home + power goes to the first screen, trackball + power doesn't load a screen, but turns a blue led on.
I have adb. How can I do it using that??

Does adb see your device?
At cmd prompt type
adb devices
If it shows up type
adb remount
If that works...
adb shell
You will have

Type the commands in the post above after putting a recovery image on your sd card.
If the first step does not work, you may be bricked.

Just to clarify, the phone does boot up, and is fully functional aside from the [home] key working. I assume if I follow those directions, I could possibly use the android default img, and restore that, and unroot the phone for return possibilities?

I tried to type that and now my E, and R keys are dead...I even tried purchasing Better Terminal Emulator on the news that I can use the virtual keyboard and/or copy paste text. While this works, it allows SU, but when I type
PHP:
adb reboot recovery
it says "sh: adb: not found" So what I figured I'm stuck doing is to restore it to non-root status, or is there a way I can run commands on it from my laptop? The phone itself works great, makes calls, sends txt messages, just won't let me press the [home] key, and now apparently the E, and R keys.

adb is ran from your computer, not terminal.
and yes, your home key not working means you won't be flashing a new rom through recovery anytime soon.
Once I figure out how to push an update package(rc33) and upgrade to cupcake/donut, will it be effectively unrooted(for purposes of sending it back)?

you don't push it. and you don't technically "upgrade" to cupcake. you downgrade.

I was having the exact same problem last night, following the same instructions. I still could not figure out how to sideload the OTA, so I ended up just flashing the update and starting from fresh. Wish I had the answer for you.

100% Stock, yes! 1 week old.
Yes i have set up ADB
I have followed the instruction until this part (i cannot post any link sorry, not authorized by xda)
The following ADB commands are for Windows machines. If you’re using a Mac, just add “./” before each command, for example: “./adb reboot bootloader”.
Assuming you device is already connected to your computer via USB and USB Debugging is enabled, you need to re-start it in fastboot mode. Follow one of the two methods below. Option A may be preferable because it’s another confirmation that your computer recognizes your Nexus device.
A) Type “adb reboot bootloader”
B) Turn your device off, then turn it back on while holding down the relevant key combinations for your device. For many devices it’s Volume Up + Volume Down + Power. You can see what your device’s key combinations are here.
The fastboot menu will appear and you should see Start in the top right. Press Volume Up till it changes to Recovery. Press the Power button to select it.
You will see an Android with a red exclamation point icon, press and hold the Power key, then press the Volume up key to show the Recovery Menu.
You will get a new menu. Navigate to apply update from adb and select it by pressing the Power button.
In the command window — make sure you are in the directory where ADB and Fastboot reside — type: “adb sideload [the full name of the file].zip” without the brackets around the file name.
The update will install and reach 100 percent.
Reboot and enjoy the latest version of Android Marshmallow.

There are lots of additional steps in that guide and not always the simplest way of doing it.
First thing to do is boot into recovery.
- Turn off the phone.
- Hold volume down + power
- At the bootloader screen, use volume keys to navigate to recovery and press power to select#
- At the Red warning triangle, hold power then press volume up.
At this stage, type "adb devices" in your command prompt and see if it returns your serial number or not. If it does, you can follow the steps to use adb to flash the update.
Please note, the guide talks about USB debugging. This only works in android. Nothing you need to do needs to be done via android so this is nonsense. Also the MTP option only works in android, so setting this in settings as a fix is also nonsense.

Could be a driver issue. You'll need to check device manager. Perhaps uninstall the existing drivers and let it auto detect.
Failing that, install the Naked driver from my adb and fastboot thread (Nexus 6 general > Sticky roll-up thread > Adb and fastboot. What is it?)
I had the same issue with you until i did the following: I used wugfresh's nexus utility. Then I downloaded the respective file from XDA and saved it in the same folder as the Wugfresh's tool. Restarted in Recovery mode and chose 'update from adb'. Connected the phone with the usb having USB debugging on from before going to recovery. Started the CMD window from Wugfresh's tool (Advanced Utilities -> Launch) and check that the phone is connected (I think "adb devices") . Then "adb sideload xxxx.zip" and waited for the process to finish.
Instruction here: androidpolice 2012/11/13/android-4-2-build-jop40c-rolling-out-to-the-nexus-7-now-manual-download-link-available/
You do not have to install the full Android utility. Just use wugfresh;s cmd screen. Good luck!

Thank you guys! But after this "happy"night, i woke up to the OTA for marshmallow arrived on my phone, so see you guys on the rooting section instead, Thank you thank you for the help
[Sorry, this belongs in the Q & A area, but there's no option to delete or move it.]
Here are the hardware button combinations that work on my OnePlus 6T:
[volume up + power] hold until you see the red dot logo, then release theyour phone will boot to system.
[volume down + power] hold for a few seconds until the black and white keyboard appears (maybe the keyboard is only if you have a login PIN set up?) this will boot the phone to recovery mode.
[volume up + volume down + power] hold for a few seconds until you see the Fastboot label then release. This will put the in bootloader mode.
Starting with the phone powered off and NOT connected to your computer, press and hold [volume up + volume down] as you plug the phone into your computer. This will put the phone into EDL mode, which is required in order to use the MSM tool. The screen of the phone will be black but if you followed the procedure the Qualcomm device should appear under the Ports section of Windows Device Manager.
I was unable to get to FastbootD. Here's what happened when I tried various commands:
1.) when in regular fastboot (bootloader) mode and connected to my PC via USB, from a command prompt I typed "fastboot reboot fastboot" the phone only rebooted to the operating system and not to the fastbootD screen.
2.) when in bootloader, as above, I typed "fastboot reboot bootloader", the phone rebooted to the regular fastboot screen. However, I suspected this was not the same thing as "fastboot reboot fastboot" because why would there be 2 identical commands?
3.) the "adb reboot" command would not work when I was in bootloader mode. Duh! I needed to be in ADB mode for ADB commands to work. In bootloader mode I needed to use a Fastboot command. Still, I had downloaded and unzipped the latest adb/fastboot tools and set up the Windows PATH to point to the unzipped folder. Also, I checked the version numbers of both from the command prompt but still [fastboot reboot fastboot] only rebooted my phone to system. What the heck!?
4.) this all seemed to happen after booting into EDL mode the day before. I booted into EDL mode so I could check if I had the proper Qualcomm driver installed (incase I had to use the MSM tool --yes the driver was installed and functioning). I didn't actually need to use the MSM tool at that time so I didn't ever run it but I'd had some difficulty getting the phone to reboot to system so I assumed my trouble with fastbootD originated with that. Wrong!
SOLUTION: It turned out to be a hidden instance of outdated adb/fastboot that kept running in lieu of the newly downloaded copies, in spite of my having correctly set up the Windows PATH. (more on this below in my reply of Jan 9, 2022).

adb reboot recovery does work. Weirdly, adb reboot bootloader will work ONCE then if I try to issue the command a second time, adb can't see my device. If I unplug the phone from USB, restart the phone then plug it back in, I can again use adb once.

I can get to fastboot. Just not by using the volume up + power combo and I can't re-enter fastboot by using [fastboot reboot fastboot] from the command line. The command line issue is of more importance, ultimately, but I think it's reasonable to assume the root cause of both is the same since they happened at the same time.
Can you check if System>Developer Options>Advanced Reboot is enabled?

It changed at some point and OP never updated their docs. (I think it changed when A10 hit).
To get into fastboot mode. You now have to make sure you're not connected to USB and hold vol+, vol-, and power and that will launch fastboot mode.
Also maybe semi related if it's not launching at all, is to do a factory reset from within the OS. I had a really odd issue recently with recovery mode and it not booting into recovery from fastboot, adb, or key combo press. Factory reset from within the OS somehow fixed it.

Yes, I have this option enabled. Using this method is one of the ways I am able to get to fastboot. I am just not able to get to fastboot using [fastboot reboot fastboot] from a command prompt (used to work just fine) and I am not able to get to fastboot by holding the [volume up + power] (this also used to work just fine).

I don't know about that. A few days ago volume up + power used to work just fine. Also a few days ago, I also used to be able to issue fastboot reboot fastboot from a command line and have it work fine.
Now what happens when issue the command fastboot reboot fastboot is that my phone appears to begin the reboot cycle. A message in the command window appears, "rebooting into fastboot" then on the next line, "< waiting for any device >" and meanwhile my phone just boots into the Oxygen OS. If at that point I select "bootloader" from the advanced power button menu, the phone reboots into fastboot and the message in the command window reads, "fastboot: error: failed to boot into userspace fastboot; one or more components might be unbootable."
If I then issue the command, fastboot reboot bootloader, that reboots promptly into fastboot, but I don't believe "bootloader fastboot" is the same thing as "userspace fastboot", although the states look identical on the screen.
After revisiting this issue again and reading every post I could find I realized the only explanation was outdated fastboot, and since they're packaged together, adb also. This time I did a extra thorough search of all the drives and sure enough there was a super old instance of adb.exe & fastboot.exe in a place I'd never thought to look. So I deleted those files and now adb and fastboot work as expected.
I know, it seems obvious now. But there were references to those old files in windows system settings that took precedence over my PATH setting that I didn't realize were there. Ive since deleted those other references but I wanted to mention this in case other people are wondering why the PATH they set up isn't working.
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?

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!

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?

See if you can find the right incremental updates here: https://drive.google.com/drive/u/0/mobile/folders/1BZuFF4ZwYHCjIWua-INiEFe1YItjAYz2
I'm on crDroid, I just flashed from the standard 13.0.586 ROM.

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.

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!
