Hello! Your videos are Great! My device is 841nd v7. Can i use a 16Mb chip? Can you suggest me a chip to use? If a have no chip programmer, there are another way? can i put the 'blank' fhash, and use a console to flash a firmware? Thanks
some routers have JTAG interface to do that, but I donot know if your V7 has, please check wiki.openwrt.org/toh/tp-link/tl-wr841nd but you need JTAG tool to write anyway
I've not tested this but it may be possible to leave the orignal chip on the board, deconnect the CS-pin and solder the new chip dead-bug-style ontop of the old one (excluding the CS-pin). Then, with a switch and two pull-up resitors, connect the CS-pins to the CS-pad on the board. Now it may be possible to 1. boot the router with the old chip 2. dd the old chip into RAM 3. move the running linux into RAM and chroot or something 4. flip the switch to select the new chip 5. dd the image from RAM to the new chip Bonus: If you screw up the contents of the new Chip you're just a reboot away from your old backup chip...
What chip do you use to replace the existing - and what is the number on the existing (in my V9 the 4MByte chip is a MX25L3206E, and it might give me a hint on the replacement chip) ??
Nice video. By the way, what we have to do when a given device is not supported by Openwrt ? Does it be solved just by intall the propely device driver into OpenWrt and rebuilt it in order to it work fine ❓
Hello! I changed it to 8MB flash drive, everything works fine, but WIFI dropped like a device. Please tell me how to activate it WIFi module. (on a 4MB flash drive everything works fine)
Did you by any chance have the flash chips dump? I'm looking for a working dump of the wr841n v11's chip. My chip is messed up, and serial connection is not working properly and tftp isn't working either, My last resort is to find a working dump of a wr841n v11 and flash is with an eeprom programmer

Great Video, Thank you for this. Question, the USB adapter you had where you copied the one chip from the other, can that also be used for single chip to USB PC so you can access filesystem? Also, does that adapter support SOP16 or only SOP8? I believe these systems use MIPS Linux and i'd like to modify the web server files such as the html and json code.
Hi. I have a 841nv9 with 8mb flash but I have only a power led. Can you please help me? Can you please send me a link to download a backup off your 841nv9 8mb flash router? Pleasee Pleaseeeeeeee
Hi would you mine to make tutorial on WR840N(EU) V2.I already tried in webgui but it failed 18005. I think it is lock. I need to know the procedure via serial ttl. Thanks!
Well my router is now flashed with openwrt. In TFTD32 instead of wr840nv2_tp_recovery.bin I change to wr840nv2_en_tp_recovery.bin and it works fine now :)

Dear Sirs, I'm in need of the copy of the EPROM from the WR841ND. Because, during the recording process accidentally deleted the wrong address of the EEPROM (Cfeon q32b-104hip) using the Serial programming method on the port (PJ1) of the router. Now the router is completely dead. No Serial (JP2) activity. No Ethernet clock activity. No led blick. Only some LEDs are lit: Led Power ON Led Config OFF Led WLAN OFF Led WAN or Internet ON Led Ethernet 1 ,2 ,3 ON Led Ethernet 4 OFF Led WPS OFF Anyone who can help me, thank you.

You don't need to modify the firmware for 8mb? Just copy from 4mb to 8mb?

I usually use Winbond 25Q64
