Hi, by mistake, I bricked my MR3020 Rev: 1.2 by flashing my backup mtd2.bin, failsafe mode do not working and even tpl command after autoboot doesnt work with serial, once I keep pressing wps button while plugging in power it ends up inside the TFTP auto update firmware, but I got always the same error with all firmwares i'd tried [product id verify fail!], thank you in advance for your help!

Try harder to get into uboot. Have you soldered in a pull-up resistor as mentioned in the wiki?
Timing is also crucial. A common trick is to copy the string tpl into the clipboard and then hitting the hotkey for pasting the clipboard content rapidly.

After hours and hours of trying, I finally solved the problem, after having tested jumpers one by one I figured out that indeed the TX jumper was broken, I changed it and now i can get easly into uboot with tpl command after "Autobooting in 1 second" line, so I hope this will help people!

MBS: thank you so much for your response and your help!
