No matter the phone firmware, "Patch boot(disable dm_veriti and force encrypt)" operation always ends with this:

So UFI succsessfully patched the boot but for some reason unable to write it back to phone.
In manual mode I could read or write anything I want without errors.

My system is Win7 x32 and I tried different USB ports and drivers. I think it's a bug.
Do UFI saves patched boot image somewhere so I could write it manually?

I tried this on another computer with Win7 x64 with multicore CPU.
Everything worked out OK. Boot was patched and succsessfully written.

Please, fix your software to work win Win7 x32 systems AND/OR add a possibility to save patched boot to some directory for manual write.

Radiotrance Hello,
Thanks for the info, for patch boot procedure, the UFI folder must install intoroot of windows system installation drive(drive C:).
But will investigate more if some system got problem with that.
