Here with another TK880 issue

[WRAK968]

So it seems like every time I order another TK880 I have some form of issue lol.

So I purchased a TK880H which I guess was used by a fire marshals office. When I went to program it, I was prompted for a password which I do not have. I read around and someone said to hold "Shift" and type SYSTEM to bypass the password. No luck. So I figured ok, rewrite the firmware should clear the password, except the radio will not go into firmware update mode.

Last ditch effort, I tried to write too the radio, again, I was asked for a password. I've shot an e-mail to the seller but something tells me he wont know the password either, so I called the number on the sticker which is to a communications shop. Hopefully they can help (And hopefully the radio wasn't stolen)

Should this fail, does anyone else have any ideas?

Checking first, are these lines of data/code that I am modifying?

And thanks for the reply.

You need to get a windows hex editor. Then you can load in the binary file and edit the specific memory location.

The attached file is an example I did to do a hex edit hack on a Kenwood NX-411 code plug to get on the Ham 33cm band. The radio programming software wouldn't allow the entry of the frequencies.
