Soft bricked Philips PI3100z2 need rom dump topic

Hi I have this tablet, after a root wanted to change the font, from now on do not want to run. I need to someone who has this model has provided me a dump of the system. I can still enter the recovery, but when trying to, write it orginal font by update.zip, verification error appears update. Probably because of the signature. I think that if someone has provided me the correct update.zip with fonts, that he returned to life. Thanks in advance.
