I would like to do some basic debugging using my 2nd hand wndr3800, however I found that the uboot is replaced to some other customized version, tftp seems not working.
The idea is to flash back to official uboot.
I searched and found only uboot for wndr3700 from https://sourceforge.net/projects/officialnetgearfirmware/files/
I wonder since the hardware between wndr3700 (v1, v2) and wndr3800 has little difference can I flash the wndr3700 uboot to my wndr3800?
I went through that link, it does not mention anything about uboot difference between wndr3700 and wndr3800.
By the way, the uboot in my router is just their customized. It's good for application puspose, but when I tried to use tftp command it never reaches the host.
You can download the original 3800 uboot from my community build's download site. I have stored there the OEM u-boot (mtd0) and u-bootenv (mtd1) binaries of 3700v1, 3700v2 and 3800.
Download site: (see "art partition binary contents" dir)
There are also OpenWrt firmware binaries from 2015, which images have been modified so that it is possible to remove the write-protection from mtd0 and mtd1. (Normally mtd0 and mtd1 are write protected.)
