Rebranding the Atheros 928x cards - The guide

Not sure.
I am using various versions found elsewhere, but did not modify anything myself.
Atheros branch from Google code:

two versions from here:

different iwleeprom versions either report all OK, or complain about "Write verify error", but rom does not change.

like below:

Code:
# ./iwleeprom -d 0000:02:00.0 -i mod.rom
Using device 0000:02:00.0 [RW] AR9300 Wireless Adapter (PCI-E)

EEPROM has been written from 'mod.rom'

You should modify the iwleeprom code as shown in the guide.
 
modified iwleeprom as in (your) posts #77 and #99, but still the same error as above.

but why is rom dump 1024 bytes? shouldn't be 512 bytes?

My dump files are all 4096 bytes. I don't know why, but it worked so I never looked into it.

Perhaps your troubles are because you're forgetting to use 'sudo'...

interesting. the other guide on insanelymac also talked about 4k dump. strange I never got one. will go looking why.

nope. you get nowhere as regular user. can't open /dev/mem

In the version of iwleeprom I used, you'd get no errors and it would proceed as if it was working, but was ineffective at writing the result.

Sounds like you're using different stuff.
 
atheros branch from google code behaves exactly like that, no errors, no result.
still, dump is 1024 bytes or 1k. maybe this is different for AR9380?

I will get a AR928X card and play and see if there's any difference.

The version I used prints the offset being used during the dump/flash process. It allows you to verify you modified the right section of code.
 
all good with AR9285, 4k dump size, no strange output like I get with AR9380:
Trying EEPROM access...
OTP address out of range: 0fff
OTP address out of range: 1001

What would happen if I try to rebrand AR9285 to AR9380 to bypass whitelist, then use Clover patch to recognize card as AR9285? Would this work?

Assuming AR9380 is on your whitelist... yes.

But Clover doesn't really help you here. Use FakePCIID.kext instead.
