I can get into download mode no problem, but I have yet been unable to get into any recovery mode. using vol up + home + power and releasing power at boot screen.
Hold the buttons down until it enters recovery. Had the same issue before I got TWRP installed.
Hello, i'm trying from a few days to install TWRP and Custom Rom on my LeTV Le1 Pro, but unfortunately i still cant get in bootloader mode. When using the command from the ADB "adb reboot bootloader" or just the simple combination of the keys - Volume down+power button, i've got the Linux Penguin for around 5 seconds and after that the phone vibrates and start as normal he should do when pressing only the power button.
Facing the same problem here
Some one plz help, I'm facing the same problem here
After you press the vol - and off the ? shos, then hold vol + and off and you will enter recovery mode (if twrp is installed).
I succesfully can flash TWRP to recovery_ramdisk via fastboot. PHONE and FRP are unlocked. My phone is bricked and when i boot to OS i get "ERROR MODE Attention! ..." And i cant go to twrp by holding volume up + power key. But i can go to some kind of recovery mode by pressing all buttons (volume up, volume down and power key). Can somebody help me?
Thanks.
My phone is HUAWEI WAS-LX1C482
I just deleted System particion with fastboot. but i dont know how to install android now...
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
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
