I made the same mistake, and I will tell you my story and also maybe it will certainly aid you via your difficulty.Refer to the installation guide for maintaining your root discovered here:http://www.droidrzr....912verizonenus/Rumors that I uncovered were NOT true (in my case):SafeStrap must be disabledI was screwed and also have to simply return my phoneI first check out issues about a pre-install folder, so I discovered a nice member that uploaded his preinstall folder that will work if you usage RootExplorer and relocation the original preinstall you have actually (make certain you clear your folder of every little thing first) and install his preinstall folder.Link to preinstall folder I used:http://min.us/luvOq7eSyK4Hd (Taken from http://forum.xda-dev....php?p=20612911)If your OTA still is providing you an error via something alengthy of the lines of app_check_fail and offering you a blur_linkedin.apk (for example) then proceed analysis this overview.You may have actually gained an error equivalent to mine:Verifying existing system...assert failed: apply_patch_check("/system/app/blur_linkedin.apk", "14edad57cef3b955a15ff5c3a0d6e519f3949dbc", "ad9896a7e8589427d5073babccbe6513cfc79773")E:Error in /tmp/sideload/package.zip(Status 7)Installation aborted.I solved this by utilizing RootExplorer, going into /system/apps/ and also pasting in whatever I got from a folder I downloaded of a pre-OTA Droid RAZR that consists of every one of the bloatware you may or might not have actually removed. Just rearea every little thing in your /system/apps/ folder with this. Don"t clear it out prior to choose the preinstall, just copy, paste, rearea.Link to backup I used:http://little bit.ly/vwkbDw (from http://forum.xda-dev...d.php?t=1406550).All of these finally fixed my error and I had the ability to upgrade from .744 to .748 utilizing the main OTA on my original rom. I re-rooted making use of the VooDoo RootKeeper app from the industry, reinstalled RazrSafeStrap.apk (found here:http://www.droidrzr....tems-on-1-razr/), then had actually to regain mechanism using the SafeStrap food selection to ensure my allowed Safe System ROM ran aacquire.If anyone is still having actually worries please reply to this thcheck out through the EXACT error the install is providing you, tell us whether you are utilizing SafeStrap, what kind of OTA (compelled or regular), and any type of other details we could discover beneficial.

Issues With Copying Over .apk"s To /system/application Directory
I"m rooted; did not uninstall any type of mechanism authenticators or files; and also only froze my apps. I"m having actually trouble with the .748 ota upday too. So when I found this overview followed the instructions thoroughly. I replaced my deleted .apk"s (DLNA, GuidedTours, and also BooksPhone) by copying them from /system/sdcard to /system/application. I selected to have my files replaced with the copy. Now I am receiving a pressure close error for every duplicated over regime. When I replicated the absent .apk"s to my /system/application brochure from my /mnt/sdcard-ext directory I mad certain they had actually correct pergoals collection as well. Any insight is appreciated, thank you. I"ll report earlier as soon as my copy is done.
