Cannot revert to stock after installing Overcome 1.2.3

[Rudolphe]

Hello All,

I'm getting a failure when trying to revert to stock after installing Overcome mod.

assert failed: getprop("ro.bootloade") == "P7100BUKB7"
E:Error in /sdcard/hc-3.1_ota-full_sam_tab_10.1.zip
(Status 7)
Installation Aborted.

Any ideas?
