Hello,

I'm looking for a compatible recent hacked English firmware version for a Chinese DS-7604N-E1/4P.

Is anyone able to supply?

Presumably you know that would have to be a 'hacked to English' tweaked version of the firmware, for that Chinese NVR model?

What's the current version of firmware?
If its old enough, it might be that the bootpara data is still in plaintext such that the device could need converted to EN from CN.

Hi it WAS V3.0.8 build 140825 (nvr from aliexpress, bought it in 2014-15) I tried to upload V3.0.10_141126 but now it's bricked. I can connect via tftp tho... just need the original file :(

The '15-beep bootloop'?

With that older device and firmware, you can fix the NVR - with a permanent conversion from a CN model to EN.

If you can carry out this conversion, there will be no need for any hacked firmware :

Good luck!
I think you'll get a good result.
The newer firmware (maybe 3.4.92 and on, I'm not exactly sure) encrypts the bootpara data if it finds it in plaintext.
That makes it more difficult, but not impossible, to modify the data to convert the device to EN.
