I am trying to downgrade from the official LineageOS 18.1 to 17.1. I successfully sideloaded the install package, but after I tapped "Reboot system now", the tablet booted into the "This tablet's bootloader is unlocked..." screen and is stuck. I cannot access the device through adb or fastboot, pressing the power key to continue does nothing, holding Power + Volume Down to force shut down causes the device to reboot into the same screen, and Volume Up + Volume Down + attaching power cable to enter download mode does nothing. Any advice would be appreciated!

You can't downgrade without a wipe, also in case you already installed OneUI 3 firmware you can't use 17.1 anymore.
For getting to download mode:
Connect the tablet to a PC, force reboot it by pressing Volume Down and Power for approximately 7 seconds, when the screen goes black immediately switch to holding Volume Down and Volume Up.
Thanks for your response - I see that that was a mistake.
I've made it into download mode and can flash the LineageOS recovery, but I'm unable to boot into recovery after that to sideload LineageOS with adb (I can't power off, and Power + Volume Up does nothing). Any suggestions?

Hold Volume Down and Power for 7 seconds again to force reboot it and when screen goes black immediately hold Volume up and Power
If you are on OneUI 3 firmware your device needs to be connected to a PC in order to boot recovery via key combination (it will just try booting system otherwise)

I've tried that a few times and it seems to try to boot to system regardless of whether it's connected to a PC or not -- it just gets stuck at "This tablet's bootloader is unlocked..." yada yada.

Which firmware are you on?
Which version of the recovery did you try to flash? 17.1 recovery won't work on oneui 3 firmware.

I believe I am using OneUI 3 (though, admittedly, I don't know how to check for sure - I'm new to all this).
I tried to flash LineageOS 17.1 nightly from 2021-03-3. Is it possible to install firmware which will allow me to use 17.1 or do I require 18.1?

OneUI 3 is samsung's Android 11 stock ROM so if you had Android 11 before installing lineage you're on Android 11/OneUI 3 firmware
For 17.1 you'd need to install e.g P610XXU2BTK2 (that was the last OneUI 2 / Android 10 stock ROM for the Wifi Model)
May I ask why you don't want to install 18.1 actually?
Edit: In case you need the firmware I mentioned above, I uploaded it here

Hi,
Im a noob. tried installing the latest lineage 14.01 nightly but twrp gave errors . I did manage to flash viperOS. Now i am unable to access twrp. Typical Power and Vol up buttons leave me stranded at the Mi screen. Nothing happens. I have enabled usb debugging , and advanced restart, and android debugging in dev options. still no change. also tried flashing recovery with command "fastboot flash recovery twrp-3.2.1-0-ido.img" with no change Any assistance would be appreciated.

First of all I think you flash wrong file as our device name is 'land' not 'ido'. Ido is code name of Redmi 3 not of redmi 3s so first download write file from development thread or officials twrp site.
Second after flashing right file press power button +volume up +volume down for recovery in all custom Rom(except miui )

Thanks that worked. i got the correct version and twrp opened and i installed lineage.
however the problem has cropped up again. i cant enter twrp using power + up buttons and it when i do a "adb reboot recovery" in linux it restarts the phone directly into lineage.
i have tried :
- reinstalling twrp with " fastboot flash recovery twrp-3.2.1-0-land.img" -no change
- Power+ up takes me to mi screen and nothing happens
- reinstalling adb-fastboot
- usb debugging is enabled in lineage

You need to press all three buttons power + up + down simultaneously for 10 second.

Hello,
i found my old zuk z1 and updated everything. TWRP to 3.2.1 and lineageos to last nightly. This was working. Then i tried a opengapps mini package for ARM. Since this, my phone can't start any more. With lineageos there was a reboot after 5 minutes to recovery and i tried to delete everything and flashed lineageos with different version, but still reboots after 5 minutes. So i tried an other image AospExtended-v7.2-ham-20200521-1100-UNOFFICIAL and now i have an endless boot screen without reboot and recovery. I can't reach it manually. I tried every Combination with Power Button, Vol up, vol down, both, and with home button. Until Vibration, 10 sek....nothing works, i can't reach recovery mode anymore
how could i recover my zuk1 ?
update, there was an error with vol down, so i can't go recovery with buttons. But you can reach it with adb and
Code:
adb reboot recovery
So I just rooted and got everything to work just fine (.33). Thought i'd smash in Viper4Android aswell.
The phone is now stuck on the logo with the red and two white dots.
I can get it to reboot with Vol+ and power, but the power-button does not let me go into recovery mode at all. It's like its disconnected.
Is there anything you can do to get into recovery/fastboot from here?
Also tried every single vol+powercombination with 0 results..
Thanks in advance.
What viper4android version did you install? And what Android version are you on?
If using Magisk 21> you should be able to hold down power button to boot into safe mode.
Hold power button and volume down and up at the same time, this should boot you into bootloader.
If you're on Android 10:
Boot into TWRP and remove module folder from data/adb/modules
Android 11 (or 10)
[Recovery][Stock OOS]Oxygen OS Stock recovery with ADB enabled
While waiting for a working TWRP for all those needful of the possibility to access their file system from recovery, e.g. for removing an offensive magisk extension preventing boot I repackaged the Stock OOS recovery but with ADB enabled...

Thanks for the reply.
I seem to have solved it (for now..).
I could not get any key to answer to my commands when i rebooted the phone (hence why i couldnt get into recovery etc.), it only went back to the loop after displaying the usual message about the bootloader being unlocked.
Holding down both volume-buttons and using the msm-tool i managed to get it back to OEM (with everything locked. Again. Lmao) so now i just gotta watch out when I install Viper again (if i do..).
Running Oxygen 11.0.3.3.IN11BA with the latest Magisk (I just patched it today)
Edit: I just used the Viper4Android that i found inside Magisk if that makes any sense.
I'll try your links and see if i have to re-flash again..
Cheers
Hello everyone. Had TWRP up attempting to install Lineage when I realized Lineage does not support Oneplus 7T Pro McLaren. I was planning on either trying to reinstall Oxygen, or maybe the unofficial Lineage. I am pretty sure I was able to reboot the phone a few times holding power & volume down. I ran into some sort of sideloading issue, rebooted using power & volume down, and tried again, and it seemed to resolve it. I was attempting to sideload one of the images, and I was getting a bad zip format message. I tried to reboot the phone holding the buttons, and it wasn't working. I selected the reboot button within TWRP, and chose system.
It rebooted, and I got the Qualcomm CrashDump Mode image.
I can reboot the phone into fastboot mode holding volume up, & volume down, & power. I don't know where to go from here.

Could you please tell me.. Is it possible to use a Windows emulator to use MsmDownloadTool V4.0.exe? I use Linux and have no access to a Windows machine.
I am trying to install LineageOS on gta4xlwifi (galaxy tab s6 LITE 2020 wifi). I successfully installed the rocovery using heimdall but after I tapped "Reboot system now", the tablet booted into the "This tablet's bootloader is unlocked..." screen and is stuck. I cannot access the recovery mode to install the ROM, pressing the power key to continue does nothing, holding Power + Volume Down to force shut down causes the device to reboot into the same screen. I can only access to download mode by holding Volume up + Volume down. Here the guide i followed: https://wiki.lineageos.org/devices/gta4xlwifi/install
Hope you can help me!
