Dear Sir,

Your phones nvdata is damaged. That is the main problem. Sadly this issue can not be fixed by the Chimera Tool. To your second question: we only have the read/write cert function for this model. You have search for a cert file, but as i said your phones nvdata is damaged thats why you can not do this.

Best Regards
Chimera Tool

Please team look into J500fn write cert. Always ask for enabling Dm+modem+Adb. And after enabling, it will still not connect, but kept asking for thesame Dm+Modem+Adb which is already enabled.
