Here we go:

NOTE: This info will only be available temporarily. I will delete it after some time, so please let me know when you have been successful.

By the way T280XXU0APC5 is a fairly early firmware the latest is T280XXU0ARL3

On lunch break atm. I'll give this a try this afternoon. Thank you.

lol I put that last line about "is this too new" as a mild joke and give you a nudge. I was pretty sure it was old. Just like most of this stock.

I'm starting to think something is wrong with this unit lol.

I flashed the provided boot.img without issue using Odin 3.13

NO errors, flash successful.
It rebooted on its own, debug pop-up did not show.
I read your instructions about booting the device while it was plugged in, gave that a try.
no pop-up. even disconnecting and reconnecting the cable does not illicit the pop-up.
I've made sure i'm trying usb 2.0 ports not 3.0 in case that would be an issue. no joy
I tried win10 ver 1803, 1809, and a a machine with pre-release on it, again, no joy.

I'm wondering If I might need to actually upgrade to a newer build to get this method to work, is that a thing?

?

Have you actually installed the USB/ADB drivers on your PC?

I suggest you factory reset in recovery then boot without the cable in then plug in the cable after it boots to the welcome screen.
Also I'm sure this will work with any firmware, but if you choose to update, update to APH3.

Factory reset from recovery - complete
reboot without device connected - complete
connect device - complete
pop-up - No joy

wow, I noticed a red-x on the charging icon when plugging into PC,
ran over to Regular charger, plugged in, confirmed no red-x
back to PC, plugged back in, No pop-up,
checked Device manager, - Shows as adb device, look back at device
POP-UP CITY *****ES!!!

frp tool worked like a charm. thank you so much

No probs. Glad you got it sorted. ;)
Cable would have been my next suggestion, wonder if its a bit dodgy, but strange it worked in download mode?

To be clear. I didnt change cables. I just plugged into a charger once and came back. Same cable. And it worked. Your guess is as good as mine.

I wouldn't worry about it. Its a hacking program so it's probably just a false positive. I have several anti malware and antivirus programs running and none give a warning.

Well, I kept it around long enough to wipe my devices, Both Malware Bytes and Defender were screaming about it. I could care less, just don't want any ransomware, as they claim this is a Trojan I let it be removed after I was done using it. Thanks again!

Also on a work computer so I don't want to take any un-necessary risks.

That's fine, better to be safe than sorry. No issues here though.

"your request has been declined for security reasons"

I have a Samsung tab A(SM-T280) and I'm having issues with the FRP unlock. Would someone be able to give me a hand please?
 
Solved t280?

Hello guys...it seems your son's are quite similar :silly:
Did this method work?
I've been bashing my head up from site to site to remove the frp...now's the school's back and he's gonna need it.
Please reply.

    Thanks for your quick reply which gives me the hope to fix the problem. With the informations i've found i am now a bit confused and not 100% sure if i am going the right way. Please correct me if I am wrong.

    I assume i would need to download the T280XXU0APH3_T280XAR0APH3_HOME.tar.md5 with almost 2GB, then mount it to Odin AP slot, then run it and it is it?
    That's correct.

    I'm hoping this method is still viable, the downgrade method. I recently came into some samsung tablets that were crytpo erased but are still frp locked. Hoping to salvage them. I tried a method for auto enabling adb, involved downloading a firmware and then using this tool to remake the firmware which was supposed to 'auto enable adb' didn't work for me. I tried obviously just flashing the firmware and that was successful however, still frp locked. I couldn't find the exact firmware mentioned above. Is there a way to see what firmware i'm on from a locked device? I haven't figured out how myself if there is. Open to any suggestion at this point. Looking over this lot of 30 + tablets
    It will always be viable because Samsung don't bother updating this device.
    However there is any easier way that doesn't require messing about downgrading.
    You will need the combo boot image though or an adb enabled boot image.

    @ashyx Still looking for that combo image. I'm a little apprehensive to download some thing's i've found when looking. Any chance you can suggest one you know works? Thanks in advance.
    I'll come back to you once I've checked.
