I'm really having trouble, have you managed to solve yours?

Did you manage to solve?
I want to install Magisk and use Magisk Hide to hide my root, but that requires flashing through custom recovery.

[Q] VS980 unable to factory reset/ enter recovery mode

Hi guy, need some help with going to recovery mode.
So, I wanted to factory reset the phone(in stock rom with supersu), but when I press it, it couldn't get to the recovery screen. And instead, it's just a dark blank screen, and the phone is still on. I can hold the power button and my phone would restart normally. So, then I tried to flash the lastest CWM to maybe flash to another rom, but when the CWM finished flashing and it couldn't enter the recovery mode, and again stuck on the dark blank screen.
Any help would be appreciated.
Software version: VS98012b
Oh yeah, these messages are from my attempt to flash cwm
adb cannot run as root in production builds
dev/block/platform/msm_sdcc.1/by-name/reovery: cannot open for write: permission denied
thanks

"no command" after installing TWRP in recovery mode

hey guys! first post but I have been lurking here and there before registering.
Sorry if this is the wrong section to post this in. I am trying to root my note 4 and I installed TWRP using Odin. Now when I go into recovery mode to flash SuperSu, it says "no command" with the android guy laying on the floor. I tried the factory reset option and I installed TWRP again but still same problem. I can still load my phone and use it as usual but now I can't go into recovery mode with TWRP and flash supersu to root it. Anyone know how I can fix this problem? Any help would be appreciated.
No one knows?

What is the model number of your Note 4? When you are at the "no command" screen, try holding the volume up button and then press the power button to take you to recovery. I'd that doesn't work try holding the power button and tapping the volume up button quickly and release all buttons and see if it allows yoj to access recovery. I'd these do not work keep trying different button combinations. I'd you still cannot access the recovery menu you may have to Odin the factory firmware and start over. Let me know what happens.

none of those button combinations work. I will install stock firmware on it again and see if that fixes the recovery.
I had this problem in the past, I think the problem was that when I was installing TWRP via Odin that I had not powered off the phone so it looked like it installed but actually didn't, try taking out the battery and then boot into recovery or download mode whatever it is that is used for Odin and install again

If you cannot get into recovery with any button combination boot to download mode and use Odin to flash all 4 files of the factory firmware. That will give you a fresh start. Let me know how it goes.

Same here
After holding volume up+middle button+power bar
I get into recovery mode but right after recovery mode it goes into “installing system update….” and then “No command” shows up and after that I get the following message and options:
Android system recovery
Volume up/down to move highlight;
power button to select.
reboot system now
apply update from ADB
apply update from external storage
apply update from cache
wipe/data/factory reset
wipe cache partition
reboot to bootloader
power down
View recovery logs
Enable cp logging
Disable cp logging
and at the bottom in yellow it says;
# MANUAL MODE #
— Appling Multi-CSC…
Applied the CSC-code : GLW
Successfully applied multi-CSC.
Any sort of help would be appreciated, thank you.

Use the VOLUME UP/DOWN BUTTONS to scroll to WIPE DATA/FACTORY RESET and let it do its thing. When it's done select REBOOT SYSTEM NOW.
Tell me what that does.

but this will erase all my data from the phone
Yes it will but it is the most likely way out of your bootloop. Before you wipe, connect your device to your PC and boot to recovery. Once your PC recognizes your device internal storage, transfer everything that you can think of.

That looks like TWRP didn't stick when you flashed it using Odin. Try a different version of Odin and flash TWRP.

So idk if you've gotten it fixed, but what worked for me was: I had been turning on the phone after odin did its thing, and that caused the oem recovery to reinstall itself. So instead of letting odin auto boot be ready to push the volume up button to put it into twrp recovery. I had to remove my battery to keep it from booting fully.
We need to try another time flash. Conditions - old Odin 3.06, configured to remove reboot.

In ODIN go to 'options' and uncheck 'auto-reboot', then flash TWRP. When it's done, it won't reboot, just pull the battery for several seconds, reinsert it and boot into TWRP Recovery.
Enjoy!

Once you are in the no command screen, hold down power button and then press volume up button once. Immediately after that, let go both buttons and you will enter stock recovery.
When you are in recovery mode, "no command" is the default screen for it. Just shortly press and release power + volume up again and menu shows. Don't hold it for too long or your phone will fully reboot to recovery again.
Thank you so much dear brothers

That's means that TWRp recovery has not been overwriting on stock recovery. In my opinion You should attempt once again to flash recovery via fastboot mode.
i am trying to boot and flash treble recovery {cosmic dan}
i am able to boot into twrp but when i press reboot int recovery from twrp ...... it goes to no command screen ..
i have tried flashing stock rom {android 9}......... screen goes to android one boot screen----until battery goes 0%
