Ms office 2007 for mac. Please first read the entire post before attempting to flash. Have got the black version of Archer C1900 from Costco and after flashing DD-WRT I was unable to revert to stock by using TFTP method. Although have figured out that the required file that the router was looking for was named ArcherC9v2_tp_recovery.bin, once the file is downloaded by the router, the file gets rejected by CFE.

Connecting with UART, the problem is that CFE ( bootloader) is reading the product-info partition to match the new firmware image against the product version of the router before attempting to flash it. DD-WRT overwrites product-info (as well as default-mac and pin) partitions making the revert to stock using TFTP method impossible. Expect Archer C9 to have the same problem since the partition layout is identical. Thanks to work already done by @Heinzek and @Aboshi I was able to create a revert to stock image that can be used directly from DD-WRT or from CFE to restore the stock firmware. Yes, that means you do not have to open the router case when using the first method. Must read before flashing: WARNING: This is for Costco Archer C1900 (black case), not for Archer C9 (white case).

For Archer C9 a similar approach can be used to create a similar image by using the original C9 firmware. WARNING: This image will overwrite not only os-image and file-system partitions but also default-mac, pin, product-info, partition-table, soft-version, support-list, profile and default-config partitions. User-config, log, radio-bk, radio and CFE will not be touched (unless you do something wrong from the command line).

As stated before, I have found that DD-WRT overwrites at least default-mac to product-info partitions and in my case since I have tried JFFS support, have found partition-table, soft-version and support-list overwritten with other data too. Since DD-WRT was not stable on my router, having intermittent disconnects on WiFi, for now was best to revert to stock until DD-WRT will be changed to not overwrite the above partitions and also have the WiFi and JFFS2 problems fixed. DISCLAIMER: Have already tried the image a few times and was able to return to stock by flashing from DD-WRT web interface. Once to stock, you can flash the original image from TP-LINK website using TP-LINK web interface.

It would be best if somebody that has UART and already opened the router case as I did would confirm first the image works as expected on his router too. Use at your own risk. After flashing from DD-WRT, do not forget to reset the router by pressing the hardware reset button until all the lights turn on. It might take 20-30 seconds until the router will be accessible after the reset. Reset will also help to restore the MAC and Pin baked in the image. Always flash it using wired connection since it's expected to be more stable and less risky especially if you do not want to open the router and restore it using UART. In case the transfer fails before being complete you might get a brick device until you open it.
