Default [Q] Lost Root After 902 Update

Yesterday my Droid Bionic received the stock 902 OTA update. Prior to the update it was running 893. I had rooted the phone via the manual Zerg method. However after this update I no longer have root. The manual Zerg method does not appear to be working after the update to 902. During step 2 after typing ./zerg it gives the error message "Cannot copy boomsh.: Permission denied". ADB is installed on my computer. Is the only way to obtain root after the 902 OTA update to flash back to stock then ForeverRoot?

Thank You,

DGSafewright

You need to run the 4ever root after the zerg rush manual root. You'll have to go back down to forever root if you want it.

Is there a "best" method to do that from .902?

I don't think there's any other way other than going back to 893 and make sure you have forever root from p3 as i heard other keep root scripts/apps weren't reliable

Many people have this issue too when they manual update to 901 and no1 figure out how to root while on 901

Only way is to go back to 893 - root - forever root

Many people tend to misunderstand when they manual root 893 they'll also have forever root its 2 separate thing

What I did was took 893 FZX file, unzip it, and then take the 902update file, unzip it, and copy the cdt.bin file from 902 to the 893 FZX. I then ran that with RSD 5.6, and that brought me back to 893. I then used rota893 from this thread http://rootzwiki.com/topic/13807-roo...3-aka-rota893/

That gave me 4ever root, and then I used stock recovery to run 902update. Everything worked for me.

But be warned that RSD will wipe the internal sdcard. Follow this post to avoid wiping.

My phone was bricked with a "Invalid CG" message it would not even boot up. This did not happen until the 902 update. I had to follow the guide here http://forum.xda-developers.com/show....php?t=1433783 and run the fix.bat to get it working again.

I'm assuming the FXZ file you used was the one from Daywalker04? Just replace the CDT.bin file with the one from the version you are currently running.
