I don't know if you managed to find the solution to this, but for anyone else out there that hasn't, just download the AutoRec app. Fixes it in seconds and flashes TWRP Recovery.

It's a bootloader issue, for me it was. If you can enter recovery, flash JB Bootloader or KK Bootloader, whatever your rom needs. it worked for me.
Autorec

Thanks for this. I just ended up back on a (brand new, mind you) G2. I've had SO many problems with rooting, recovery, download mode, etc... I have TWRP installed, stock ROM and somehow ended up getting the secure boot error only when entering download mode. My phone was booting, recovery was working, etc - just download mode seemed toasted. AutoRec fixed it - so, thanks for posting this!
I had the same issue, if some of you want to know how I fixed it these steps might help you too...
What you need is :
Any versoin of stock kdz. I used 11a. GET FROM HERE
LG Universal drivers. Get them here
If you have verizon get your driver here
KDZ Flash tool. GET IT HERE
1- Power off your phone completely ... remove battery etc...
2- Plug the UsB cable to your phone and your computer.
3- Hold down volume up and power button and enter in the download mode
4- If you in download mode you can now flash any KDZ file using the method in one of the guide above or find it using google.
after flashing you will have the stock rom installed. I was on 4.2 and for some reason i was not able to root with "ioroot" until i updated to 4.4!
so make sure you are on 4.4 to do the root
later you can install any recovery. I installed autorec.apk and then booted into recovery and flashed latest version of twrp
thats about it.... but don't install MIUI that rom is stupid

have you try vol down + power button ( LG Logo ) then Hold Vol down + Power ? till you get to factory reset ! and power key again will take you back to recovery
WOW! Thank You soooooooooooooo much! I flashed a cloudyg3 backup from VK Rom and got this error but this method worked!
Just download AutoRec and choose to flash TWRP. Worked for me.

Did you try and flashed rom again ( odin) ?? another option would be to flash (odin) a custom recovery see if it let you enter it and do a factory reset ..only problem is it will trigger your knox bit to 1..
@lloop: Are you completely stock, or did you attempt to install a custom recovery? The behavior you describe is identical to the behavior witness by myself and others when trying to install TWRP 2.8.5.0 on the S4.
One other thing that might help here. On occasion I've had the device get stuck in recovery. Going into download mode, cancelling download mode, and then holding down the buttons to go into recovery often works.

Let's get the major possible error out of here first. Make sure you wait for at least 45 minutes for the ROM to boot before trying anything else. Next, you must hold volume up+power button not till you get the vibration but till you see the ASUS logo. I too was stuck for quite some time till I realized that.

My phone is currently bricked... My first initial attempted install of twrp gave me a pass but the phone would not boot into twrp. It is stuck at the galaxy S8+ logo... I can boot into download mode and thats all... holding the power + bixby + volume up buttons does nothing. I have tried to flash twrp several times now and keep getting a fail in odin. I have also tried flashing a stock rom several times as well but odin fails at that too... followed xda giudes for both procedures and no luck. Any ideas? Any help would be greatly appreciated... Thank You

WORKED!! Thank You So Much!!
Thought I had a very expensive paperweight until you replied
Had to install a stock rom with Odin afterwards to get everything working right again but all restored now from backup. Think I will wait before attempting to install TWRP again until after it is more compatible with AQG5...
In any event I am one happy dude
WHEW!!!
Thanks Again!!!
Hi,
I've looked everywhere before writing this so please forgive me as I saw there are a number of threads similar to this but couldn't find an answer.
Have rooted the phone a few days ago and flashed the Alexis Rom Oreo2.1S9PORT. As I had several apps that where acting up (no MIcrosoft Active Sync, no Outlook notifications among other things) I made a bit of a mess of it and decided to reset the phone by erasing all contents. As I went to boot up again the phone was in loop.
It goes on download mode and have tried with ODIN to reflash AP, BL, CP, CSC read everywhere looked on youtube but Odin fails each time. I've downloaded samsung drivers and firmwares to have Samsung Oreo back but to no avail.
Could someone please give me a hand in restarting the phone somehow? It's now in loop and I will wait until it dies down from battery failure as suggested in some threads in here.
Sorry to pester you.
Newbie...:crying:
latest ODIN screenshot. I don't know what more to try...please help...
Can you boot into Recovery Mode?
(Power off your phone, than hold: Bixby + volume up + power on button until you see the recovery mode)

No unfortunately. NOw the phone is battery drained.
THis is the Downloading mode. I can't think of what to do unfortunately. I've tried 3 or 4 firmwares as well.
Since I deleted through the phone system reset and not through TWRP (which I've now lost obviously) what would be the best way to reflash the mod (or the original Samsung one for that matter)?
ok I thought I made some progress, I've managed to reinstall TWRP and flashed again the Rom, Rom fix, and AOD fix. I was able to check the options of the Rom and the ROm installed succesfully. As I went to reboot I got stuck again in a loop with the SAMSUNG logo flashing continuosly. I can feel I'm close to a solution, could you point me in the right direction please?
The continuosly boot-loop could be the firmware doesnt match the Rom.
If you are game, try installing Renovate Ice: https://forum.xda-developers.com/ga...ovate-ice-g950-g955-android-7-0-aqdg-t3598040
Click the orange colored RENOVATE ICE WEBPAGE link.
From the menu choose FIRMWARE, download and flash.
Then download and flash R.Ice rom - follow the How to Flash guide

Thanks a lot. I managed alone 5 minutes ago. Reflashed the TWRP, then the Oreo ROM, and then the samsung firmware... result now I have a working fresh empty Samsung S8 with all Samsung apps... I now know how to do it. :laugh::laugh::laugh:
