Will 4ever root make the update fail? I can't get the update to install. I'm stock rooted with 4ever root. I uninstalled Bionic Bootstrapper and wiped cache and still no luck. I don't want to FDR if I don't have to and I'd rather not do HOB if I can avoid it. I'd really just rather the update work the way it's supposed to. Do I need to unfreeze all bloat?
I had the same problem. I unfroze all bloat and even used Voodoo OTA Rootkeeper to unroot. And it still didn't work. So,I did some research to find out where the OTA was stored. Then, I looked in the /cache/ folder where the OTA can be found as "Blur_Version.5.9.905.XT875.Verizon.en.US.zip" and discovered a last_log file in the /cache/recovery/ folder. At the end of the log file there are these statements:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
blk: partition "emstorage" size 8603435008 not a multiple of io_buffer_size 524288blk: partition "" size 63861041152 not a multiple of io_buffer_size 524288

Installation aborted.
>>>>>>>>>>>>>>>>>>>>>
From this I infer that a checksum is being applied to the mount_ext3.sh file and the installation is aborted if the checksum does not match. Coincidentally, that is the file that has a couple of chmod commands added to it to keep root permanent. I don't know if a factory reset will put that file back to its original state. I also don't know if it would be possible to restore root after doing so. I also don't know what other checks may fail if that one succeeds. However, it seems clear that VZW is, at a minimum, attempting to prevent rooted phones from taking the OTA to ICS by failing the installation on phones that have used the forever root method to maintain root through OTA updates.
