Edit: I got everything to work, if you're having the same problem scroll to my next comment where I go through the steps of what I did. I'm so happy
Hey guys! MIUI is great, isn't it? I posted a thread because I'm having a huge problem, but maybe I can get my answer here. I flashed GB 2.3.5 onto my DX through SBF Flash for Linux, it worked fine, and I rooted it with the 1-click Root app for Windows. Root worked, I put Droid2Bootstrap on my phone, went into recovery, did the data/cache and dalvik cache wipe like everyone's been saying, and then went to install update from zip>choose zip(or whatever the option is)>MIUI Shadow (or again, whatever the DX version is called). It worked great, I booted into MIUI and had absolutely no troubles with it the first time. However, when I rebooted my phone, the boot took forever (like, 5 minutes) and when I opened up my phone again, it had done a factory reset, wiping all my configurations, downloads, accounts, and even service(I had to call in and activate my phone again), and Torch/Themes apps wouldn't work at all. I rebooted again and once again it did a clean wipe, and now every time my phone powers down and back on it does this factory reset crap. I have v. 1.9.23 MIUI. I may try flashing 8.19.11 because I believe that's the last stable version for Droid X and see if it works. I'm thinking it installed in my phone's memory for some reason instead of the hard drive, kind of like when you boot a Linux LiveCD, so it's not saving my settings. Any help would be appreciated!
TL;DR Every time I boot my Droid X (GB 2.3.5 SBF Flashed with Linux, rooted with 1-click Root for Windows app) with MIUI v. 1.9.23 for Droid X, it does a complete factory reset. Torch app and Themes app have stopped working as well.
