Bought a R34 with an AVIC-MRZ90 and it shows a splash screen when powered on then just goes into black screen, buttons still have pink lights tho... What to do? I kinda want this thing to work...

Hello Buddy! I've seen you post and help few people with their nav systems. Could you possibly help me too? I use a Avic-Mrz05 and I tried to change it from Japanese to English but I accidentally deleted both my  PF090JPJPN.LNG and PF90JPENG.LNG from both the PRG0 and PRG1 files. My texts are all gone and I cannot fix it.  I'm pretty much freaking out as I dont have a backup of those files. Can you please help me by providing me step by step guide and the required files to fix my issue. 

I know I am asking for a lot but please help me with this.

Thanks in Advance.

 

Here are the files.

PF110JPMTB.LNG

PF090JPENG.LNG

PF090JPJPN.LNG

PF110JPENG.LNG

PF110JPJPN.LNG

PF110JPMEN.LNG
