Hi all.
Did a stupid thing.
I downloaded firmware file for my Galaxy S20 Ultra 5G (SM-G988B) Exynos as an MD5 file and extracted the file which came out as a .img file instead of .lz4 (which I overlooked until the damage was done!).
So not noticing the file was the wrong type, I used 7-Zip to tar it, copied it to my phone's SD card, then patched it with latest Magisk manager app. After this, I copied it back to my laptop and flashed this file using Odin.
Result: Phone goes to insecure boot warning screen but of course here it goes wrong:
It won't proceed to booting up
Power+volume up key combination or power alone do nothing no matter how long you hold them in
It boots to to same insecure boot warning screen if you use either power+volume down, or power+volume down+volume up key combination with cable unplugged. With cable plugged in it restarts to a charging icon, which promptly freezes, and stays on the screen even if you unplug the cable.
I have managed to get it into stock recovery by holding power+volume up+volume down randomly once in a while (usually it goes to insecure boot warning screen as usual), but if I select Reboot to bootloader, it does not manage to open download mode, and hangs on red text that says "entering fastboot mode"
QUESTION: If I can get it back into recovery, is there a way to re-flash stock firmware without download mode on this device using ADB (or any other method)?
Or is my phone a brick for good?
FIXED!
I managed to flash an Android 11 One UI 3.0 Beta via ADB sideload. While it didn't finish properly due to corrupted boot image and possibly not the prerequisite firmware, all was not lost. It ran okay right to the end, when it said "installation aborted".
Once I had got this far Download mode was working again, THANK HEAVENS!
Opened Odin, and flashed away. I'm now back on Stock firmware and didn't even lose my data thanks to the vbmeta_disabled file I flashed in USERDATA section.
Talk about getting out of Jail!

I have ZE55ML 4gb version. Ok so, tried manually applying an ota update to my phone, i renamed it to MOFD_SUPDATE or whatever its supposed to be. I did not unroot or anything. It didnt work i got the error error executing updater binary in zip. So then I wiped my cach/dalvik, data, and system like a moron reboot into recovery and tried the update again... well it failed again... so I tried to just reboot my phone and now its stuck on the damn ASUS powered by android screen... I can turn it off by holding the power button and turn it on the same way and it will be stuck there. I would have been able to fix this by myself but I cant boot into bootloader/recovery. Power+volume up doesnt do and neither does Power+volume down.... So what do I do am I just ****ed?

Hold power for about 10+ seconds and it will turn off.
Go to Original Android Developement and then find pre-rooted rom. The latest for the 551ML is 2.20.40.90, put the phone in bootloader mode and install the system.img file using fastboot.
Next time unroot...
Lol....
I wanted to downgrade to 5.0 to unlock the bootloader and install a custom recovery and ROM. Used the official FW from the Asus page, installed it from within the OS (android MM stock). It all went as expected until at the end of the install it rebooted and got into the bootloader screen instead of booting normally. It won't go into recovery.
Phone will NOT turn on with power button + volume down button, not ever.
Power button + volume up does nothing, it turns the phone on just like the power button alone would do.
Once in the stock bootloader if I select [recovery mode] it will simply reset and go back to where I was. I never get the dead android error, it just go back to the bootloader select menu
I get this screen

What can I do? all the tutorials I seen either asume I can get into recovery or use power button + volume down button which in my case doesn't works
Find images of system, ifwi, recovery etc. and fastboot flash them. you can try first with recovery only. the adb command will be "fastboot flash recovery recovery.
img" just search the forum plenty of guides here

I looked at the guides, most require recovery on the phone to work (it doesnt here, just reboots back into the bootloader) and for some reason adb can't find this phone, tried on 2 different computers
BTW I tried with another android phone and adb worked just fine
How is it possible no computer can even tell this phone is connected at all?
Hello.
So, my Tab has been working great for a while, with magisk and TWRP installed, today i thought i would upgrade magisk, so i did, both the manager and flashed the latest zip (directly in manager). Happy as can be, i rebooted the tab only to see it now boots up with a broken/distorted samsung logo, and it just keeps on trying booting, but never actually starts up.

So what im wondering, is there any way to save my tab without deleting everything? I have spent a fair amount of time setting it up, just the way i want it. (I can still boot into TWRP, and taking a backup of everything to my sdcard while writing this)
I tried unsu.zip it removed magisk, but still did not help.
Would it be enough to flash this with odin? (seems i cant copy files to device with usb in twrp)
Originak Marshmallow bootloader (I am on 6.0.1)
T800
T800XXU1CPI2
Edit: Flashing bootloader downloaded from xda did not work, "invalid bootloader" message in Odin
Edit2: Bit the bullet and flashed stock in odin, works fine now.

Delete Magisk from twrp and flash the previous one that worked correctly
Ok, so this is how it went.
I uninstalled Magisk 18.1 via TWRP using the latest uninstaller zip. Unfortunately, my phone would not boot any more. Not in to the the system, not into recovery.
So I went to fastboot and tried to boot the TWRP image (fastboot boot twrp-3.2.3-0-daisy_zero.img). It loaded TWRP and then in the TWRP recovery, because it was set to boot at slot B, I changed it in TWRP to boot into slot A. After I restarted the phone, there is only the black screen. I can't reset the phone, I can't get in to fastboot, nothing. Basically it is bricked. It won't even show that it is charging.
Can anything be done? I have broken my system before, but always had no problems with restoring it with flashing threw fastboot. But now I can't get to fastboot.
I was using stock rom with Pie v 1.0.4.0.
Really appreciate the help.

That´s really strange... Will windows detect the phone when you connect it?
Maybe you´re in edl-mode. If yes, you could get out of it by pressing pwr for more then 10 seconds.
If that doesn´t help and you will not be alble to do anything (incl. going to fastboot) you can restore you phone by going to edl by usng the test point method. But thant will break your warranty - you have to open the phone...
If you want to do it you need to do the following.
1. Download latest fastboot rom and MiFlash
2. Install MiFlash, unpack fastboot rom and selct extracted folder in MIFlash.
3. Open your phone: https://www.youtube.com/watch?v=PmpHdqRUlDA
4. Remove the metal cover over the mainboard
5. Remove battery
6. short these both pins: https://www.youtube.com/watch?v=mhsRv42rsqI
7. connect your phone to pc (in device manager you should see "qualcomm qdloader 9008"
8. In MiFlash click on refresh (now you should see something with com-port)
9. On the lower right corner you can selct "clean all", "save user data" and "clean all and lock" - if you were on 10.0.3.0 before, you can select "save user data" if not, you have to wipe by selecting "clean all". Now click "flash"
I did this once and needed a few tries... It´s a bit tricky to connect both pins and then the phone to pc - after the 4th try I got it running.
I had the problem of locked bootloader and a not booting phone...
Hi!
Yes, Windows detects the device. I can see the phone in the device manager by the name Qualcomm HS-USB diagnostics 900E (COM10).
If I hold power on and volume up or down, I can hear via Windows sound that it gets reconnected. So there is some life still in it.
The device is also detectable by MiFlash tool. But unfortunately since I can't get into Fastboot, I can't flash it. I've been trying to flash it, but this is where I get (it just stays here no matter how long I leave the device):

I know about the method you posted. I still have a year and a half warranty on the phone. So I will sent it on repair and see what they will say. Maybe the won't notice and I will be able to keep my warranty.
i am in the same situation right now, after try to update the twrp, what tool you use to open the phone?.
I think you can also use the deepflashcable for the same effect.
I TRIED TO FLASH LINEAGE OS WITH TWRP, BUT I DIDN'T EVEN MAKE IT TO THE WIPE STEP! I USED THESE INSTRUCTIONS: https://www.howtogeek.com/348545/how-to-install-lineageos-on-android/ And I made it to Step 4 without any problems. When I pressed the reboot button, however, it said “OS Not Installed” or something. The guide stated that it would automatically reboot to recovery, but it is currently not booting at all. The battery charging icon doesn't even turn off, and it's just stuck on. The only option I have is to use the power button+vol down+home key to enter download mode. When i try to choose the reboot button, as it takes me to the Samsung boot screen, and I'm stuck there unless i press the download mode button again, in after which I'm taken to the battery charging icon AGAIN. I attempted to boot into recovery mode, but it was unsuccessful. Please assist me!
Edit after much searching i finally booted into twrp recovery but when i was doing that i got this error "recovery is not seandroid enforcing". but i could finally get to twrp. the only problem is that when im trying to install crdroid its giving an error a pic of which im attatching. i tried 2 customs roms still dint work...
