I have TP-Link TL-MR 3420 v2. I have mistake I download firmware CC 15.05.1 for WZRHPG300NHV1 and flash on TLMR3420.
and now TLMR3420 is bricked now.
I found that the Flash on TLMR3420 is SPANSION FL032PIF 212ww001 A.
My friend use flash firmware by flash machine( take off spansion chip from circuit mainboard to device and flash it by program on PC) and I do not know the firmware i can flash by this method.
i stock firmware and openwrt-15.05.1-ar71xx-generic-tl-mr3420-v2-squashfs-factory.bin to spansion chip all not working, 4 led on lan light.

If you just flashed the firmware for a different device, then chances are very high that the bootloader is still operational. So, you should be able to recover by connecting via serial line: https://wiki.openwrt.org/toh/tp-link/tl … erial_line
Read about the basics and pay attention to the voltage level of 3.3V: https://wiki.openwrt.org/doc/hardware/port.serial
I try many times, I bought USB-TLL, RS232-TLL but all of them damage now. I will buy it to connect to serial. Please tell me do I need conect VCC from TLL to router?
If I detached spanson chipset from circuit mainboad to flash by devive which firmware i can flash on it?
does firmware "http://www.friedzombie.com/tplink-stripped-firmware/" can flash?

NEVER connect VCC, or you will permanently damage your router.

Hi all
I run comand:
cat /proc/mtd
This command will show MTD partitions:
dev: size erasesize name
mtd0: 00020000 00010000 "u-boot"
mtd1: 000eeb70 00010000 "kernel"
mtd2: 00ee1490 00010000 "rootfs"
mtd3: 00c60000 00010000 "rootfs_data"
mtd4: 00010000 00010000 "art"
mtd5: 00fd0000 00010000 "firmware"
then I run
cat /dev/mtd0 > /tmp/backup_fullflash.bin
cat /dev/mtd5 >> /tmp/backup_fullflash.bin
cat /dev/mtd4 >> /tmp/backup_fullflash.bin
at last file backup_fullflash.bin at tmp can flash for my ROUTER?
The discussion might have continued from here.
