[Android Q&A, Help & Troubleshooting] caine0001:
The only reason I even write this is because you have the install-recovery.sh file like my phone whereas those getting newer Express i437s do not have that file and thus do not have the luxury of just renaming a file to get back to stock. They have to flash a stock recovery every time they want to get back to it. So since our phones are the same I figured what worked on mine, might work on yours.

If you were already rooted, then you should have used OTA RootKeeper to do a Temp unroot. I named "install-recovery.sh" back to original name and of course reverted to stock recovery. I then did a Temporary unroot with RootKeeper and then ran the update. It updated and I then used RootKeeper to Restore root and installed CWM 6.0.3.4 and everything was fine. The update did not remove root at all.

I can also tell you that when I did the first JB update it appeared I was no longer rooted but I reinstalled Superuser just as a user app (since it didn't recognize I was rooted and wouldn't let me install as a system app) and then ran Root Checker and I really did have root, even though before I reinstalled Superuser, Root Checker would say I was not rooted. It just didn't appear like I was rooted until I put Superuser back on. I didn't have to use motochopper again.

I know I had done everything I could to speed it up including turning off all the Window animation settings along with anything else that I could find that I could do without. It didn't do any good. Until now. I agree with you, this is a mystery, but whatever happened to my phone with this tiny 80MB update unleashed its full potential. Pretty cool from where I am sitting....:cool:

When I tried doing that everyone that tried it said it installed fine and everything worked fine, except it didn't update the modem for some reason and that prevented them from using wifi, when using my Nandroid. You can try and if they already have 4.1.2 it might work, but I am going to put my money on the same thing happening that happened with my Nandroid. I am going to guess that it won't update the modem and thus they won't be able to use wifi. I know that is what will happen if they have ICS on at the time they do the update. Let me know if you get yours to work or if it does the same as mine did.

I am going to eat a bullet simply to satisfy curiosity. By now you all know that I am ecstatic about how this new update has improved my phone's performance. I need to know if it was a fluke or if this is repeatable. I also have read that some say that this 80MB update removes root. I have got to know the answer to these questions, definitively. So I am going to take my Express i437 back to stock recovery, restore original ICS, and then work my way back up to this newest update and the latest CWM from there. This time I will not use OTA RootKeeper to preserve my root. Once done I will post back to let you guys know if my phone only shows these improvements with the newest update or does it even have the improved performance once this is all done and I will let you know whether it unrooted or not when applying any of these updates OTA. Wish me luck! Here I go. I will report back in what I am assuming will be a couple of hours, hopefully less, but maybe more. (So this is what a sacrificial lamb feels like. I am going to hate myself if my phone does not have these performance improvements once I get back to where I am now). :crying:
