is that the Full LOG.???
i am a little confused as to Why you Decided to customise the FS.
Try to Attach again, please use a fully Charged Battery,
Once attached you need to remove RSA , then Procede to disable OTp imei
then Change GDFS imei (last 6 didgets only)
once Done you need to Restore Firmware, or Flash same Main/arm.
if it wont remove RSA, then you are going to Have to attach by Testpoint, for which
a K750 is Quite easy.(pictures and procedure in manual.)

if Rsa wont Remove, then you Must attach by testpoint,
Cause you are Not able to Customise Filesystem while Rsa is Active, (its a lock)
