Larry thank you so much it actually worked in case someone lese has this problem im going to post waht i did
i downloaded the file
flashed the modem.bin file via twrp. I just put it on the phone i did not use the sd card
then i rewrote the imei with ns pro verision 6.7.1 (this phone was on 4.3)
i know have my imei back, and i know also i have the phone in 100 percent working condition with a full imei.
TAKE MY ADVICE AND BACK UP THE NV ITEMS before doing a s3 747 or 999 on z3 box just in case. I have spent close to 3 days trying to fix these phones.
Thank you Larry so very very much. If you have a link to paypal i will donate to you.
