I am trying to restore stock firmware on my TP-Link TL-WR902AC but nit being able to. The router retrieves the stock firmware using TFTP from my PC but after that, the link lights keep flashing (invalid configuration). I can go back to OpenWRT but not back to stock. If anyone can help, it will be appreciated.
Unfortunately, mine is V3 and it only looks for and reads tp_recovery.bin file. I renamed the stock firmware and renamed it to tp_recovery.bin and that did not help. Went into all blinking mode.
Then maybe try to rename it to wr902acv3_un_tp_recovery.bin ?
Yes, I tried that to no avail. This model+version only looks for a file named tp_recovery.bin unlike other models.
In case no one else comes up with a better idea, you could ask the vendor for help.
I have posted the same question on their forum as well. Thanks

The vendor has replied, they are not familiar with 3rd party roms and hence, cannot help.
Solved it with the help of this article:
remove first 257*512 bytes of the stock firmware. Then use OpenWRT firmware upgrade to apply this modified file.
