Hi. I need help please.

I'm using 33375 on a TL-WDR4300 and can't upgrade or downgrade the device.

I read this: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=311642&start=0

I couldn't even start the guide as my ssh option is disabled (grayed). Any clue?

Any help is appreciated as I really don't understand much about these stuff.

Thanks a lot!

This is what I did for my TP-Link TL-WDR3600v1:

1. enable ssh or telnet (ssh preferred/secure) - Web Gui -> Services -> Services (Username:root, same as admin password you use for web gui
2. cd /tmp/
3. download factory-to-ddwrt.bin - wget ftp://ftp.dd-wrt.com/betas/2017/10-10-2017-r33492/tplink_tl-wdr3600v1/factory-to-ddwrt.bin - update url to point to your device and the buid you want
4. cd ~ (/tmp/root)
5. dd if=/dev/mtdblock6 of=/tmp/boot.bin bs=1 count=131072 - "think" the same value can be applied to yours, but please check/confirm
6. wait for it to finish - took about 30-45 sec
7. cd /tmp/
8. cat factory-to-ddwrt.bin >> boot.bin
9. mtd -f write boot.bin fullflash
10. wait for it to finish - too about 45 sec
11. reboot

router came back successfully, and with it's same settings/configuration prior.

hope this at least helps a little
