Hi All,

I've messed up! I used DZO's mrz99 usb file to try and change from Japanese to English, on my mrz90 and didn't back up as everyone seems to have updated without a problem.

Now my screen is messed up.20180318_143417.thumb.jpg.f5dbc624ebea0204a4883f97b7aa2b77.jpg20180318_143406.thumb.jpg.4d024c203dd8fba4b3acf78b4d7a03fd.jpg

Thanks for your reply. Sorry it has taken so long to try this solution.

I downloaded the files and have them on an SD card, but I do not have the copy or paste functions on my unit? See attached picture.

Hi

In an attempt to change the language using the 2011 version given above this has happened to my screen(refer to the attached screen shots). The language has disappeared completely and blank buttons are left. Need your help in fixing this. I have also attached the contents of the langdata folder.

Perhaps you have disturbed the files in the prg0 folder. If you had made the backup then you should restore the original files. if not then try to copy the files from prg1 folder or otherwise. please inform did you delete / copy / paste manually or you used the testmode key? First try to find which folder has been disturbed (PRG0 or PRG1)? Then try to restore from the other folder. The files for MRZ05 can be downloaded from earlier posts, if required.

Hi Javed

Thank you for your prompt response brother. I did these changes in the prog0 folder and manually deleted the file first and then pasted the new file. I made a mistake i did not take the backup before doing all this. Should i simply just go to prog1 folder and copy any missing files into prog0 ? And that would solve the problem ? Can you share amy links ?

Yes, you only need to put the missing files from prg1. That will solve the problem.
