Hello to everyone !, I recently downloaded this build made the upgrade to my router, now I can't upgrade my router to another build because the "upgrade firmware" page on my router now it doesnt work, it stays in upgrading.... and nothing happens after, so i want to know first where i can find a good build for my router, because in the router database i only know the builds 36527,36410,36330, 36247, so can i use one of this ones to reflash my router ?, and second one what i can do now that i don't have the option to upgrade my router through the firmware upgrade page, i'd like to know, guys if you experienced something like, and also want to know if there is a way to upgrade my router via ethernet port. 'cause i dont have any other way to do so. thank you in advance !

A lot of information can be found in the forum guide lines this is recommended reading.
Link in my signature at the bottom of this post, those will tell among other interesting titbits not to use the router database, 40599 is particularly bad build.

Installing builds via the command line is possible
see the installation wiki but it can differ per router model so research carefully.

You can try another web browser to upgrade, chromium based browser do not play nice with some DDWRT builds

Is the v3.x even officially supported? Last update was WIP with donated hardware needed:

https://wiki.dd-wrt.com/wiki/index.php/Supported_Devices#TP-Link

https://dd-wrt.com/support/router-database/?model=MR3420_3.x

It probably won't upgrade if there is a checksum error, most likely you will have to flash via command line. Not even sure how you got 40559 to flash correctly in the first place. Or am I mistaking the v3.0 being for DD-WRT v3.0 instead of router model version? Clarity is always a good thing when you post.
