[Samsung Galaxy Tab A series Questions & Answers] mrstuffandthings:
I am not an informed authority whatsoever but I did have quite a few close calls with my same device and I repeatedly managed to get it going. That must hurt to hear without a clear step by step specific with links instructions I know but let me not mislead you either. What good is that?! Well I can refer you to some of the resources I had luck with , it’s been a few years since too so I will go look and see if I have anything concrete , off the top of my head I want to say thanks to magisk the bootloader never did get unlocked , and I only ran the boot.img thru the app and then had my tarp ready to flash right after, be persistent I must have mangled and recovered over two dozen times here and there and again ambiguous encouragement empty as it is I can say from my experience that more than a few things that worked ended up being very simple but minor factors such as unchecking the auto reboot and flashing the twrp right after , another saving grace came in the form of a few die hard twrp flushable zips that enabled simple functions while in twrp bc I remember I would get as far as twrp and then loose the bootable os until I had reflashed the correct boot from inside twrp and I recall dmverity can be mitigated with a zip flashed inside twrp , now that sounds great but only just the right twrp would allow for this flashing feature at all so again hit and miss , I’ll go look at some of those files and review before I make any specific suggestions which would drive me nuts but if your lucky I was actually just noticing I still had an old custom rom that I had cooked up with one of those command line rom kitchens, so standby for real info but for now off hand …

Androidfilehost.com was a killer source of roms and where I found the working twrp

Back then samfirm was already depreciated but still worked and it was the fastest around but

Jonny boy , again knowing I don’t really know I want to say your good to go as I flashed all manner of rom from all over but I do remember something about I think the us version that seemed XAR less appealing I think bc it was a little more locked down but you would do well of course to refer to that list of the country codes for the roms obv, and as far as twrp I found mine on that android file host but on that same site was an identical looking version that once inside couldn’t flash or mount things properly , see what the trick was , was once armed with a twrp flashable zip i would wipe everything and include the dmverity disabled and whatever else , the patched boot.img And so if your careful even if you flash the wrong twrp first you can inside still flash that other one and reboot to it , my custom rom is nothing to get interested in all it were was a trimmed down stock , tho I did manage later to get some neat custom boot animations , I’ll check out my old files and return sooner this time
