Bootloop after magisk uninstall! "No command" - LG V40 Questions & Answers

Hello!
I tried to remove root and magisk. I opened the magisk app and went trough with "full uninstall", done trough the app.
The phone rebooted, but never reads ROM files, it gets stuck on "No command" screen with an laying android with the stomach open a red triangle with the "!" sign on it.
How the heck do I make this phone usable again ? :crying:

@vbenkovskyy on telegram helped me out! Now we have reflashed European kdz file and phone works again.

Hey this exact thing happened to me.
Any ideas how to fix it, or should I reach out to vlad?

NVM.. fixed now.

If I'm not mistaken, factory data reset is a smooth way to un-root...

this happened to me i just followed the instructions for changing bootloader in lgup discussion did a flashboot reboot to reboot into twrp without, then erased and installed magisk again, last after i rebooted in ti o it just used lg bridge to download and install the latest rom

SM-G800F rooted stuck in bootscreen (got TWRP access)

I wanted to try and hopefully learn little about rooting. Have been reading forumposts and tutorials for hours before I started.
Then I got this problem that I have been trying to solve for hours. But my conclusion is I need help solving it.
Tested on this phone that just were collecting dust.
Samsung Galaxy S5 Mini (SM-G800F) and I think it was running 4.4.2. (this is all I remember off the top of my head)
Problem / What happend (long version):
Rooted phone. Downloaded SuperSU and Flashify and installed TWRP 3.0.0 (http://forum.xda-developers.com/galaxy-s5-mini/orig-development/recovery-twrp-3-0-0-t3313775). I had no SD-card so I skipped doing a backup. Everything worked fine (for a normal user). Downladed a Root Uninstaller app also Debloater-setup-v3.90.exe (http://forum.xda-developers.com/devdb/project/dl/?id=12623). Did not freeze or uninstall anything before checking in this forum that it was OK. But after a while I could not access my homescreen it just turned up blank but I could still use other functions/apps. Rebooted the phone in order to get it to work but got stuck at the bootscreen. Tried to fix it via TWRP but the program freezes after a while or just reboots the phone back into Samsung bootscreen.
Problem / What happend (short version):
Rooted - got Flashify and SuperSU
TWRP 3.0.0 installed (no backup made)
Debloater-setup-v3.90.exe and some Root Uninstaller app used (searched on this forum before doing any changes)
Homescreen just blank, other functions/apps worked
Rebooted the phone and got stuck at Samsung bootscreen
TWRP access but the program freezes/reboot after short time
I did try "Factory reset". But the screen froze and the phone slowly started to heat up.
Later on I searched about it and it might have something to do with KNOX?
Any solution is fine since I don't have anything thats need to be saved. I can try any working stock/custom ROM (just not sure how to get it into the phone, yet).
Yes I am a novice so the simplest thing might even work.
Have you tried to flash stock ROM for your device using Odin? If it fails you may want to check this:
http://forum.xda-developers.com/galaxy-s5-mini/help/g800f-failed-odin-firmware-upgrade-fail-t3131782
If it doesn't fix your phone you may have a hardware problem.

Please help me out! Huge issue!

Hello guys,
I have a Samsung Galaxy S7 Edge (SM-G930F) - ARM64x which is Android 6.0.1 (Marshmallow).
I flashed the correct Xposed Framework following this thread: http://forum.xda-developers.com/showthread.php?t=3034811
Once I flashed, I could not boot my phone at all. It is stuck at the Android Logo when it starts up with a red error at the top stating: "kernel is not seandroid enforcing".
I can enter TWRP (Recovery) and I can enter the Downloading-Mode.
The huge issue is that I do not have the Uninstaller Zip in my storage anywhere (I did not know that I would need it in case something like this would happen).
I tried entering the Downloading-Mode to download the Uninstaller into my storage, but I could not even do that since the storage does not even show up at all, as if I have the USB Debugging off (it was not off, but I suppose it is off now).
I suppose I can use Odin. But I tried flashing TWRP again, nothing changed. I do not have a Stock ROM/Firmware, so I downloaded one and tried flashing it. It did not work.
I tried going to the Recovery to Wipe everything and such, and it still did not work.
What am I to do?
Please help me out!
Dozens of thanks!

OP3T stuck on boot up screen after root?

Hi Guys,
I recently flashed to OOS 4.0.1, I wiped the phone with fastboot -w and followed instructions on here to flash the full ROM file, anyway so that went fine, by the end of that I had a functional, rooted phone on OOS 4.0.1,
But then I went to download Snapchat, everytime I tried to log in, it says it had temporarily failed, so I went through some troubleshooting steps and decided to wipe my phone, re install OOS 4.0.1 without root, and try again, that has worked, my friend said he had the same issue and that he had to root after installing and logging into Snapchat, so I have gone to root again, sideloaded fine in TWRP recovery like i have done in the past, but now my phone is stuck on the OnePlus logo where you have the red dot with two spinning white dots going round, been like this for 10 minutes now, I know the boot can take longer but it has never taken this long, I've got it plugged and will just wait for an answer as this is doing my head in!!
Cheers guys,

I've run into the same problem, how did you end up fixing it?
This is odd? My suggestion would be to just flash stock 4.0.1 again or w/e it is and then install Magisk from the app store and install the root from there. That should do the trick .

Soft bricked my phone after uninstalling Magisk

Hello, first of all sorry for my lack of tech knowledge.
So, I rooted my phone and tried to use Magisk for Gcam. Could not make it work so I was going to unroot my phone and started by unistalling magisk.
When I did it, it went to restart and I got the "no command" massage. By reading articles I first went to factory reset. I didn't work.
Later I tried Installing the TWRP, firstly it got me a black screen, but now I used adb to try to get to fastboot again to unistall it got stuck with a Android One logo freeze and I can't get to the fastboot.
No idea on what to do.
Edit: got to fastboot again by pressing power and vol down for a couple of seconds
A guy on Reddit solved it. All I had to do was to flash the stock boot.img I had before the root. I tried a couple until It was the right one and my phone resurrected.
FOR OTHER USERS WITH THE SAME PROBLEM: IF YOU GET "NO COMMAND" AFTER UNROOTING WITH MAGISK : flash the stock boot.img
If you are bricked with magisk then dont waste your time on flashing via fastboot sideload because nothing can unbrick.
The only way to recover your phone is via EDL mode ,
Search in the fourm and go through test point , your phone will be alive .

This is probably one of the reasons why you bricked it in the first place. Don't just "try some", but read the forum over and over again until you're 100% sure you flash the right thing (rom, recovery, boot,..) for your particular phone version from the first time!
You were lucky to be able to resurrect it now, but flashing wrong things doesn't always give you that second chance!
That being said, rooting your phone with magisk and getting gcam to work is pretty easy, if you find the right tutorial for your specific device and follow their steps.

Mi A2 Bricked, Solved

Hi, I need some help with my Mi A2.
I tried to install the RR Rom and was already struggeling in the beginning to get twrp up and running, after I got twrp running Ive got, while trying to install the RR rom (yes I did wipe everything that needed to be btw) error code 1 . So I tried to just shut my phone off and retried the installation after being back in twrp. and it did sort of install, I wasnt getting any error this time but after rebooting or atleast trying to I was stuck in a bootloop. soooo, I went back into twrp and tried wiping everything except internal storage and did an factory reset. but now fastboot mode wont let me use any commands for example "fastboot boot twrp.img" it just responds with "command write failed" or something like that. and when trying to boot into the "system" I get an blackscreen with a smal text in the top left corner saying "press any key to shutdown".
I hope someone can help me I tried now for hours to get anything running.
as a side-note I am not that new to flashing roms but, I have no idea what I screwed up this time.
Thanks for anyone that tries to help!
Edit: Using MiFlash and downloading the stock room from Xiaomi worked.
