If you already flashed with 130820 CN firmware, you cannot use the above method because the u-boot may difference and cannot downgrade to lower level, you must use TTL and I had flashed successfully using this method, following the command and pictures -
Original CN firmware -

TTL wiring -

After flash -

Command -
1. Setup the tftp server at pc with IP 192.168.1.100, put the firmware file at the same folder of tftp server,use lan cable from router lan port to tftp server.
2. Type "tpl" when see the "auto booting in 1 second" on the console. you will get ap135>
3. tftp 0x80060000 ????.bin (depend on what you want to flash, but file must cut the boot loader already and 8126464 bytes, if you want the English C7 firmware, use the ARCHERC7-V1_130729_up.bin)
4. erase 0x9f020000 +0x7c0000
5. cp.b 0x80060000 0x9f020000 0x7c0000
6. bootm 0x9f020000
Use at your own risk, many thanks for the original writer Ck-NoSFeRaTU at above link and provide very detail information.

轉1080p睇到了
如果轉了C7 130729,將來係咪可以直接download官方 firmware web update?
ching有冇發現C7 130729有冇咩大bug?

1. 0130126 Web 直刷 openwrt-r38298-tl-wdr7500-v2-squashfs-factory.bin 使中文firmware 變成 openwrt
2. 由於要刷英文c7, 先係7500 openwrt 用 mtd 強改為C7，或用TTL線刷改為C7
3. 在7500 openwrt 用 telnet 192.168.1.1 進入
4. 確定要用firmware 位置及名稱，用wget 取得
5. cd /tmp 進入 tmp folder
6. wget http://nosferatu.g0x.ru/pub/wdr7500/????.bin. 注意地址及名稱
7. 取得 firmware 後，入 mtd -r write ???.bin firmware
YouTube 教學為7500 cn web 去7500openwrt, 7500 openwrt mtd 去 c7 openwrt, c7 openwrt web 去 c7 Eng firmware, 理論上可在7500 open 用mtd 直去C7ENg，但我未試過. 注意所有firmware 用去 bootloader file .
YouTube 可改，1080p

使唔使"去 bootloader file"?

no, I use the file directly download from TP with bootloader. Flash these file in the web page of 7500(c7), no need telnet, no need ttl
