Not something I tend to work on, can't remember the last time I tried to recover an Android device. A family friend brought me their Tab 3 to have the battery replaced as it was in a reboot loop and he had it diagnosed already, I ordered a genuine battery, replaced and it powered on fine but stuck at the Samsung logo.
I tried a factory reset in recovery and wiped the cache etc. but this didn't help. I installed Kies and the Samsung drivers, device manager sees the device correctly and Kies says "Connecting" but it never connects. I read this isn't uncommon so downloaded Odin and put in download mode, Odin sees the device, I downloaded P5210XXUBOB1_P5210BTUBOC1_HOME.tar.md5 but it fails to write.
I have managed to flash twrp-126.96.36.199-p5210.tar.md5 using Odin and booted to recovery, when I go to the wipe menu I was seeing "E:Unable to mount '/system'" so I went to the wipe menu and wiped data, then cache then I was able to wipe system. I put P5210XXUBOB1_P5210BTUBOC1_BTU.zip onto the SD and tried to flash but it failed.

Can anyone help me get a stock image for this and advise what to try next? It is the GT-P5210.
