i will post that hopefully tomorrow,maybe by them a developer chimes in too.
also to think of it now, one wlan chip surely wasnt working before i ventured with it into ddwrt, i thought the flash is corrupt, but i think the wlan chip is bad, but i am sure ddwrt should run anyway.

Now,i dont want to remove the chip again...
Why would you remove the chip? If you use a 3.3v programmer you can read write while the chip is still on board.
If you have the black version of CH341a than be aware it is incorrectly designed and manufactured and puts out 5v on the data pins. The 5v will be enough for the router to be powered up and it will also try to access the flash memory so you won't be able to program it.. very true.
There is a mod for it to correct the issue. The correct 3.3v will not be enough for the board to come alive so nothing will interrupt the programmer to read/write.
By the way the flash chip is a 3.3v chip so 5v not the best thing to use there anyway.
I have purchased another C8 v1 that has never been flashed with custom fw.
Here is the full dump.
Before you flash it open the file with a hex editor
go to 0xf00008 and change the mac address to the one on the label of your router. also go to 0xf00208 and change the Wireless password/PIN.
Save it then flash it to your router. Log in to webGUI and do a factory reset.
All mac addresses and wifi ssid will be corrected automatically to the one printed on the back of your router.

Yes indeed I have black version, but even so I don't have the jumper cable to be able to latch onto the pins while it is still on board.
Lets hope there is no need to flash the chip at all this time around
