So I have this Samsung TAB 2, GT P5100 is the model, it is stuck on a screen saying “Frimware upgrade encountered an error, boot to recovery mode using Keis.” even after I successfuly flashed a stock firmware on it, the same screen still shows up. My guess is that the NAND is somehow broken or something.. Any ideas? Thanks in advance!
Hi! Did you try flashing your phone with the repair firmware? Note: Some user had the same problem he said that he got it fixed when he flashed the MODEM file (through Odin of course).
