XT910/GSM bricked? Tried RSD Lite - Motorola Droid RAZR

I decided to flash a factory image since the GPS was not working anymore with whatever ROM I tried, plus random problems. The phone was previously set up with CM10.1 and BMM.
Installed RSD Lite, Moto drivers, downloaded several stock ROMs.
From the factory recovery mode I cannot flash any of those zip files so I proceed with RSD lite. I flashed "9.8.2O-124_SPUEM-14_S7_USASPDRICS01O2UKE1007.0R_USASPDRJBO2GB_P013_A012_p2b_S1FF_fb.xml.zip" which is a retail UK JB image. The phone shows the very first boot screen (red logo) and then the screen goes blank. The computer still sees an MTP device, though only in device manager.
I've tried installing other images but they are an older type (ICS I guess, 01.6.7.2-180&01.6.5.1-167) and RSD shows an error while trying to flash the first file from the archive.
Oh, I still have the "Customer error: contact dealer" on the first boot screen, I think this was from a ICS to JB upgrade with CID deletion(?).
I've already flashed twice using RSD, deleted cache+data, rebooted and left the phone to start up for ten of minutes, don't know what to do. RSD lite reports that flashing was ok.

U did a factory reset in stock recovery? U cannot flash a ics image after flashing jb via rsd. Try again jb EU image than go to stock recovery and perform the wipes
Tapped from my RazR

Got it "fixed", finally. I had to go back into the stock boot/recovery menu and choose "BP Tools", last option from the menu and then it booted normally.
I still have to do this after each reboot because it boots to the black screen: hold the three buttons together until it flashes (which means a hard reboot), let go of the power button, press power button again while the other two are still pressed.
On the plus side the GPS started working again after factory reflash which it was kind of expected since the same chip is providing also WiFi and bluetooth which were running fine.
I have a root question: the device was rooted with the virtual machine procedure but after a factory reset the root was lost. I had saved it using Voodoo RootKeeper and the app shows: superuser installed, device rooted, /system supports root protection, protected su available. The "root permission granted" checkbox is disabled though and no application is able to retrieve the root. The su binary is in both /bin and /xbin so I don't understand how it can not function.
Edit: ok, got it, the su binary has -rwsr-sr-x and the owner is root so random users cannot execute it. I also cannot change the permissions so I probably have to root again and figure out a way to keep the root after a factory reset. It makes sense to install BMM since it can take care of permissions.
