Than in changed from the good dump the MAC accroding to the broken units MAC.

there are some print screens of a hexeditor called i think HxD on previous pages...in any hexeditor you can search by Offset ... but before all of this yes you need a new chip... and a dump of the ``bad chip`` but in the meantime i think ubi changed all of this on newer firmwares and allso I think they encrypt some partition on the chip...try your luck

2. I compare data hex 007F0000, these not same address location. can i copying?
3. According your data, Please explain caused i saw these deff Address and deff hex value
007F110D-007F1111 = 00 27 22 4E 73 83 (Capture 1, Red circle marking)
007F0000-007F000A = 00 27 22 4F 73 83 02 27 22 4f 73 83 (Capture 2, Red circle marking)

Please read my previous post.
Your problem is not the flash, it is the dram chip. That is what you have to replace.
If you notice, during boot, your log shows 4mb ram, it must show 32mb.
Change the dram chip I have pictured in a red circle.

I see about RAM thank you. RAM should 32MB right? I didn't ask about RAM to Acidu. But I asking about Hexadecimal address such as acidu data page #1 of. I mean why offset data has different address between good nand flash compare with bad nand flash

It worked!!!!! Thanks SDA, I uploaded the file "NSM5 ... 00156D9C ... 1" and the Nanostation started perfect without errors, I did not try to upgrade to V6.0., With this it is more than enough for me.
Thank you very much for your assistance ...

Programming onboard using a clip isn't possible.
In most cases the chip is removed from the board.
I use a sofi sp8 programmer with a sop16 to dil adapter.
To read it, dd is used to read its mtd blocks, and a batch file to combine all for a full dump.
For XW hardware, you can forget about replacing the flash, as each dump is tied to the specific chip.
This also goes for some later versions of XM hardware.
