Hello! First of, I'm pretty new here and only modded one Xbox 360 so far (Trinity) so please double check all my suggestions or wait for someone with more experience to reply. But as I've done it recently I still have fresh memories of what procedure is. As far I understand only one bad block is not a big problem. Beside that looks like your is relatively high in the address space, so it shouldn't affect writing an ECC block which is located at first 0x4F bytes (please check that this is also true for your type of motherboard). Consistency of that read error tells that your soldering should be good. So, if I was at your situation I would try to write ECC, boot to Xell and extract CPU key. If successful you then should be able to create hacked or retail NAND with build option and your or donor NAND if your be corrupted beyond repair (which is unlikely with just one bad block). After that you could try to write new NAND and J-Runner should remap bad blocks for you so console should work fine. Be sure to check videos below for better understanding of how to deal with bad blocks and corrupted NAND before you do something.

Oh my... Sorry, looks like I haven't searched hard enough. I've found your post dated 2016 year saying "tu 4 is messed up on unitiy". Is it referring the same problem? So it won't be fixed?

Heya, folks! Many thanks to this forum and the devs of various homebrew stuff here! Got a lot of useful information here that helped me to RGH-mod my first Xbox 360 (and first game console in general, yeah I know, kinda late for the party). So, it appears that TU4 for Rock Band 3 which hosted on Unity is corrupted. For some reason there's two of them (TitleUpdateID 21727 and TitleUpdateID 21618) but both of them have hash 470E718DF5EF08812F62B95D8B06A53CAE967969 and equal size 5353472. If you try to download any of them through Aurora you get "The TitleUpdate download hash did not match server. Discarding..." in the logs no matter how many times you try. I've tried to download them through browser but they appear to be the identical with each other and with already downloaded by Aurora. I've tried to manually place them in place where game can load them and still no luck. So, I've searched the web for a different source and found one on the digiex.net, downloaded and placed at Xbox and Aurora finally showed it at "Installed" tab in the game info! I compared this third file with others and it seems slightly larger (5365760). And finally I tried it with game and in showed at the HUD that TU4 is loaded and that means that the last one is correct. I also tried to check file's hash manually but it's either not SHA1 (even it look like one) or Aurora generates it by mixing file data with something else.
