Hello guys I got a x920 and was working good until it started doing something similar like Samsung Galaxy S3 Sudden Death. The phone would randomly get a screen freeze, and the half bottom of the screen got distorted like green and pink lines, then slowly, the pixels were turning to black until the whole screen gets black, but the backlight would remain on. I had to pull the battery out, and sometimes the phone would work again instantly, some other times, it wouldn't turn on, only after some time, and after a lot of battery pulls. But last time I got this sudden death, the phone never came back. I had the stock rom and only root. My model version is: e2001v21_v89_zlh_hd Most people with this phone have the e2001_v89_zlh_hd, and most roms on needrom.com are for e2001_v89_zlh_hd, there are a lot of roms for e2001v21_v89_zlh_hd though but I tried everything and I got DRAM Failed. There is a solution from a French guy about the DRAM failed problem, but I got the S5 rom downloaded as he stated, and can't get pass the red bar on SP flash tool. Do you have any idea what is going on with the 2 versions of the phone? People say that they read on chinese forum that v2.1 (e2001v21_v89_zlh_hd) has got different EMMC. So I guess roms from the e2001_v89_zlh_hd wont work. Do you think it might be hardware problem?
