iTuneDVR

I think you need try all combinaton & reset dvr ctrl+ [key]

Right!

Of course it's strange why 3XXX then 5XXX and after it 4XXX But it is different NVR for different purposes.

Again you 5XXX is older than 4XXX 4XXXX more powerful

What is your firmware version?

But after bootload you can enter login name & pass - so it's configured ok! Try in Hyperterminal on NCOM

NVR5232 Processor : ARMv7 Processor rev 2 (v7l) BogoMIPS : 1199.30 Features : swp half thumb fastmult vfp edsp neon vfpv3 CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x3 CPU part : 0xc08 CPU revision : 2 Hardware : ti8168evm Revision : 0000 Serial : 0000000000000000

Correct your information!!!! Why IPC? cat /proc/cpuinfo for your nvr3XXX & nvr5XXX cat /proc//mtd ?

So, if all the same but what the ploblem? Share this specs info! Your don't need to extract Challange.rar, but you must have enough time to solve your problem! Just look to mtd map and mix configure files if all the same as you told us!

Use telnet and learn the characteristics of devices! cat /proc/cpuinfo cat /proc/mtd cat /proc/version dmesg

Screenshot login menu? Firmware link? Can telnet access (possibility)? Photo DVR motherboard! (best quality)?

Today 2015-03-09 for old firmware the password is 599640

Try!

So, find key or key combination to stop autoboot! Ex: hikvision use ctrl+u

For ex: dahua use * in digit keybord (rigth) other may use specific key What COM port config on your PC?

After start your dvr and then you'll see boot log Hit any key to stop autoboot: 0 in 3 second Then you in u-boot command printenv - for enviroment list help - for help

?

Tab Driver What the files? Make photo of your PCI device!

You're right tomcctv! But maybe these manufacturers should think about it more. After all, nothing has changed. That's their problem in the first place. They lose money!!! In any case, open solution - will earn only Chinese on all others. All the others only lose!
