HI Together,
i like openwrt since a few months...
now i will update my network a little bit...
so become an second R7800 but i can not flash by TFTP
i become this massage
The Router is in TFTP Server Firmware Recovery mode NOW!
Listening on Port : 69, IP Address: 192.168.1.1 ...
Upgrade Mode
Rcv:

Done!
Bytes transferred = 21043329 (1411881 hex)
MODEL ID on image: R7800
Firmware Image MODEL ID do not match open source firmware ID
Attempt to read outside the flash area
0 bytes read: ERROR
HW ID on board: ~и_ь~и_–ц_»мы_ь~и_K
HW ID on image: 29764958+0+128+512+4x4+4x4+cascade
Firmware Image HW ID do not match Board HW ID
Board HW ID mismatch,it is forbidden to be written to flash!!
The Router is in TFTP Server Firmware Recovery mode NOW!
Listening on Port : 69, IP Address: 192.168.1.1 ...
Upgrade Mode
i´m not shure what i can do...
can anybody help me?!?
Is that a brand new device?
Or a second-hand device that somebody has modified?
HW ID on board: ~и_ь~и_–ц_»мы_ь~и_K
HW ID on image: 29764958+0+128+512+4x4+4x4+cascade
The above snippet makes me to think that somebody has overwritten the art partition (with serials, HW ID and calibration data). The HW ID looks like something in cyrilic letters, but that might just be coincidence.
The first bytes of mtd3 should look like this. First there are MACs, then the serial, and then the HW ID:

Based on what you've seen already, I'd run for the hills. The previous seems to have messed it up quite seriously, if they also damaged the wireless calibration data, the situation would be fatal.
I would suggest to do a factory reset, then install the newest Netgear OEM firmware (yes, even if that is already installed) and then do a very thorough functionality check of the device (in particular wireless, checking if the MAC addresses for WAN, LAN and both wireless cards are fine and ciorrespond to what's written on the label) - if any of that fails, run, fast, …
Ok...
the router boots every time in rescue mode!
i can install nothing... and become every time the same massage!
so nobody have an solution for my Problem?!?
Has it ever worked for you? Or has it been similar all the time?
What was installed (and running) when you got it?
What have you then done to it?
Like slh already said (and what I suspected based on your first message), it seems that the flash area where crucial devices-specific data ( wifi calibration etc. along the router MACs, serial number, and device type (HW ID)) are stored, has been damaged somehow. Either a bad flash chip, or somebody has tried modifying it and has failed. (Normally OpenWrt or the OEM firmware never write anything to that area, as it should be read-only.)
There are no easy solutions. Pretty much all solutions would include flashing the correct contents from u-boot (once you somehow get the wifi calibration tailored for your device), or removing that flash chip and reprogramming it.
What rescue mode? (I have never seen it)
Does it not allow you to install Netgear OEM firmware?
If you can, recover your losses and return the device. It's very likely that the wireless is permanently shot (corrupted calibration data, which is crucial, especially for such a highend device as this).
It's unique to each and every device (offsetting production variances in the used components, determined at multiple frequencies and temperatures), calibrated in the test run during production.
