Hmmm...that thread usually will work, especially if you flashed it using the APX mode.

Isn't that the failure you get when you don't run its magic when installing a rom. You need to update the recovery somehow.

Help please: stuck on phone to PC screen

Does anyone know how to get into download or recovery mode when Vibrant is stuck in phone to pc screen? Is it possible or is it bricked? It happened after a failed Odin flash attempt. Many thanks in advance.
Actually, gettin' out was pretty easy. I've tried holding both vol and power buttons for 10sec, release power when screen goes dark and download mode will start. Now I'm stuck in cache.rfs.

For me on Verizon Note 3 this worked, but the button combo is different. It's the same as ODIN/Download mode:
Hold Vol down, Power, and Home... then Cancel ODIN/Download mode using Vol Down.
I had this same problem where I'd got myself in a "recovery" bootloop from Baja KK ROM... I had a custom power menu that allowed you to choose recovery as a boot option as opposed to selecting it at startup (I know, so hard). I would have the Galaxy Note 3 "Custom" screen then say Recovery mode in the upper left corner in blue, then reboot, etc... Anyway this seems to set it back to normal boot mode.

You need go to download mode and flash your firmware via Odin
The Tab will not allow to go into Download mode the minute it boots up the screen you saw is coming up. How else can i get into download mode?

Turn off your tablet and now turn it on in Download Mode (press Home + Volume Down + Power buttons at the same time until the tablet turns on, then when prompted, press Volume Up button to proceed)

I tried it a few times, nothing
In the evening I try it, but I think the result will be the same
I am having same issue. Does anybody have a solution to this other than "hold down power, home, volume and enter recovery menu", this doesn't work. Is there a link to flash stock ROM through Odin somewhere out there?

A20e stuck in download mode

Hi,
I have a new a20e (a202f) out of the box.
I followed another guide to root and install twrp which turns out was wrong. I unlocked the bootloader just fine.
I have no backup, no personal boot.img or anything.
Essentially I am stuck in download mode and restarting takes me straight back to download mode.
Recovery: Error validating footer.
SW REV. CHECK FAIL (BOOTLOADER) DEVICE"
Cheers guys
What guide did you follow? You have to download your stock fw from sites like sammobile then from there you can have the boot.img and etc. Have you tried flashing stock fw using odin?
Note: Usually you flash vbmeta for footer error when you flash twrp.

It was a guide on 'unofficialtwrp.com' - I can't link things here yet.
I have since tar'ed an unpatched twrp (TWRP-3.3.1.0_A20_by_Agrim720.img) + vbmeta.img + boot.img (from https://forum.xda-developers.com/galaxy-a20/help/boo-img-a205fxxu2asfb-t4008739), then I flashed through AP on Odin and now I think it boots past the download mode but instead it now has fuzzy dark red screen with nothing legible.
Oh bugger, I've been a class A plum.
Can I get out of this horrible mess?

Well you have to use your own boot.img from your fw, not all of use the same fw that's why, some are still on u2, u3 and u4. Maybe the boot.img you got isnt the same as your fw.
Well you can start from scratch and reflash your stock fw in odin.

Try holding volume - and power and your phone will turn off, as soon as it turns off press volume + & - and plug your usb cable that is connected to a computer.
No luck with that. It displays the message about running custom os etc and to press power to continue. So I press it and it boots to the messed up red/pink/black display.

Do you mean like the one attached? If yes you havent booted to download mode.
Try booting to recovery by holding volume + and power while you turn on the phone.
There is a option there to boot to download mode.

Yes that screen. I've tried your suggestion with volume + but that also ends up with messed up screen
Yes so currently I'm unable to get to recovery (not sure it even flashed properly), unable to get to download mode, or to get the device recognised in odin.
I'm unable to power off. The screen is blank and when I press power it flickers shortly with some black/white/red pink colours around the edges, but the screen quickly turns blank.
From this position I can only restart by holding volume - and power.
This boots to the samsung logo and then the 'bootloader unlocked' warning. No amount of button configs have proved successful so far, and then I end up back at the blank screen.
I'm happy to start from scratch. I have downloaded the stock firmware but I'm simply unable to proceed.
Aslo the device is not recognised in windows at any point.
Thanks guys

Are you sure you pressed and hold volume +&- and plugging cable before the samsung logo pops up? You have to do it quickly right after the device turns off. You shoudn't see the bootloader warning if you done this quickly and correctly.

Hello -
Please trust me when I tell you that it can be fixed. I had the EXACT same problem and drove me crazy for 24 hours. You can deffinetly fix your phone once you get to download mode.
I had the same issue where I could not turn the phone OFF it just looped back and I pushed buttons for hours to no avail... Then some one told me it WILL WORK, it is just the timing of
the button pushing, AND the USB cable plug in. Sure enough he was right. It took me alot of tries and I even took my phone apart and un plugged the battery so I could controll the power
ON / OFF better and time the button's easier. Here is what I did ...
unplug battery so phone was 100% OFF.
Plug in battery ( phone is still OFF )
Hold Vol - then Hold Power and Vol -
As soon as the power started IMEDITALY PLUG IN USB ( have USB READY to be plugged in FAST )
DONT let go of buttons ... screen will flash quickly and then Imediatly let go of power keep holding Vol -
IF you timed this right, IT WILL proced to download mode. If not, then start over again from power OFF ( step 01 )
It took me 3 tries to get it ( after 50+ tries before ) lol
Now I am not sure about the battery unplugging ... maybe you dont need to, but it mad it work for me as I could control the power ON part of this now.
Getting to your battery is not very hard and there is a you tube video on how to do it... if you need help just PM ME.
Good luck friend.
When this happened to me all I did was hold volume up and volume down. Kept cord connected to computer. Connected to device during the bootloop and boom within seconds I was in download mode. It catches it once screen goes off in between the bootloop.
Sent from my SM-N950U using Tapatalk
Thanks you guys. In the end the battery died and then I could power up whilst holding vol+, straight to recovery and then I could flash stock rom.
Much appreciation for your help guys, it got me out of a pinch - it is my mother-in-law's new phone!
