Hey guys, I'll try to make this brief. I have a JTAG Xenon on 13599. I updated from 13599 to 17416. During the avatar update step, it showed it was extracting files, then showed me the E71 error. Any attempt to turn the 360 after resulted in E71. I took my backup (dumped with NAND Flasher 360 v1.2.0) and used the installed Xell Reloaded to install my backup. Well FSD loads fine as do games and the avatar editor, but if I try to go to the original 360 menu (NXE) or go into system settings via the mini-blades, it'll turn into an E71 error. This also happens with one game; The Walking Dead episode 1. So now I don't know what to do. I should also note that when I dumped my 13599 image, it showed I had 11 bad blocks. But I remember when I originally JTAG'ed the system and also when I updated my dashes a couple of times, I only had one bad block. Now it shows 11 (including the one I had way back when)! Any advice would be appreciated! I have my original stock NAND (old blades menu, 1 bad block) and the dump I got before updating today (13599, 11 bad blocks).
