[Motorola Droid RAZR] jerkwad:
I wanted to write this "guide" for all the others that may be experiencing issues such as myself and others that I've talked to and helped. It was quite a learning experience and one of those "wow, I totally screwed myself" moments, to say the least lol.

There have been quite a few posts by others that outline how to update your rooted phone with the OTA but I wanted to put it down a bit more step by step with some extra information for those that thought it might be a good idea to just DELETE some apps from the /system/app patition (myself, included) without taking a full system backup using CWM, etc. I do NOT believe that a Titanium backup is sufficient if you choose to delete the application afterwards (as I see no evidence that the [required] .odex files are part of the TiBu backups)

Due to all the requests (here is my RAZR /system/app dump):

Pre-OTA: http://bit.ly/vwkbDw

Post-OTA: http://bit.ly/rZdQgC

So here we go...

1. Settings -> About Phone -> System Updates -> "Download Now"

2. Once downloaded, choose "Install Later" (important!)

3. Open up ES File Explorer or Root Explorer or you can even use adb to shell into the system (not recommended unless you're really good at this)

4. Browse to the /cache directory

5. Copy the two files named "Blur_Version.6.11.744.XT912.Verizon.en.US.crc" and "Blur_Version.6.11.744.XT912.Verizon.en.US.zip" to the /sdcard-ext location (NOT /sdcard)

6. Download and Install (from the Market) "OTA RootKeeper"

7. Run OTA Rootkeeper and select "Protect Root" (this will preserve files and links to the root application after the update). You CAN still choose to re-root using DoomLord/Zerg method but this is a LOT easier

8.You can choose to backup your apps via TiBu if you want to be extra cautious should something go wrong (but not required).

9. Power OFF the device. Then enter Motorola Recovery mode (Hold Vol+ and Vol- and Power). Click Vol- to highlight Recovery Mode and Click Vol+ to select it. Wait for the Triangle and exclamation point and then press both Vol buttons at the same time

10. Choose to "apply update from sdcard" by using the the Vol+ or Vol- to highlight and the Power Button to select

11. Choose the update file using the same method as step 10

12. Let it run and do it's thing...here's where the problems can start. If you have no problems you can skip to step 18

13. If you receive a "Status 7" error message it is probably complaining about checksum mismatch of the file that is ALSO listed in that output. This can also happen if the file is missing

14. Record the first 4 characters of the TWO checksums that it lists (this is important, do not forget) AND the filename (usually /system/app/<somename.apk> /system/app/<somename.odex>

Having these checksums will help you locate which file you need to get you back to "good" standing. The first value indicates the SHA1 checksum of the UPDATED file (POST OTA patching) while the second value indicates the SHA1 checksum of the older file (PRE OTA patching). There are quite a few resources on these forums where people have provided their "system dump".

You can also find this information after an unsuccessful install in the /cache/recovery/last_log directory on your phone - for those that use the install method from within the Android OS (Automatic OTA Install)

15. Download one or more of these "system dumps" and extract the file named in the error. Copy it to your sdcard and then use Root Explorer or Astro to copy it to the /system/app location (you might need to make it R/W on /system/app)

15A. For the advanced users:

You can save some guess work and get the sha1 value using a utility (windows/linux) to compare the strings with what was in the error message.

IF the checksums match you might as well copy over the corresponding .odex/.apk file as well.

IF the checksums do NOT match, you might as well scrap that "system dump" and download another one (and pray)

15B. IF you are unable to locate an original razr file that matches your criteria you can also take a stab and ask someone to send you their POST-OTA file(s) that you are missing. You can also compare the SHA1 checksum OR just try and see if it works. The installer will continue forward if it detects either the CORRECT old or new file already in place (*whew*)

16. Then return to step 9. Continue steps 9-15 until the update goes through.

18. Reboot after the update is complete

19. Verify the update was successful by following step 1 (there are other ways to see the version as well)

20. Re-run OTA RootKepper and select the option to "Restore Root"

21. Disconnect any USB cable to the phone and reboot. Verify root works properly (SetCPU, TiBu, SuperUser App, etc)

IF you are unable to regain root via Step 20, then you can always use the method that you previously used to RE-root your phone (Zert/DoomLord utility)

22. FREEEEEZE your apps from now on. (at least until there is an SBF). Stop deleting anything that isn't on your sdcard-ext partition

I hope that helps some folks out. I had about 8 files to replace and it seemed that there was never a "system dump" that had all of them. I helped one user by providing just ONE file that he accidentally deleted. In turn, after the update he provided me with both (updated) files that I needed. Win-Win!

I have my old and my NEW "system-dump" files so don't hesitate to ask me for them. If I receive enough requests I will end up putting them on one of the mediafire/megaupload places. A few other places to get the system dumps are from some of the ROMS provided for the US RAZR (i had some files match from the RAZRX 1.0 ROM)

If you noticed that I skipped number 17 then you were paying close enough attention ;-)
