We (husband and I) are trying to upgrade to a lollipop ROM from 4.4.2 on our tablet. Pretty knowledgeable about flashing roms as I have been doing this for a long time. But ran into a wall last night after I was reading a cyanogen thread for the SGTab 10.1 (didn't realize there was no 3 at the end, DOH!) So I had wiped everything I should have already then realized I had the wrong ROM. So, I found this one, the right one for our tablet, and noticed in the instructions for install it said to backup EFS partition.. didn't do that because as I said I had already wiped the thing clean. So then, got the necessary files as per the OP and tried flashing the ROM file and got an error (I think it was invalid MD5), I saw the MD5 link next to the ROM link so I got that and put it on the SD card (tried a few SD cards also) as well, tried flashing again, another error.
Can anybody help me? I haven't had this issue before when flashing ROMS, and I can usually research and find the answer but not this time. We put a KitKat ROM back onto the tablet so if someone could help me with this I would very much appreciate it!!
Thanks!!
*EDIT* By the way, I have the 5210 (16gb wifi version)
