Hello mates, im trying to unbrick my tp-link devices, i was reading the posts about a year and half approximately to solve my problem but i already stuck on bootlooping... 
Nowdays i study Dev Sec Ops on college and my agenda is a trouble to solve this so... i've decided to ask help from someone more competent than me, so listing the things i know:
- How to use tftpd64.
- Set ip, mask and ports.
- Use CLI and bash algorithms.
- A little knowledge of bin archives.
- How to use a computer in general.
And now, the things i tried to solve my problem:
- Flash the "original" bin from Tp-link site.
- Tried to merge the openwrt unofficial branch with original tp-link bin.
- Using bin files from github who description match with my problem.
- Search specifically my problem on this forum and tried to follow the steps (didn't work but i think bcause not tried enough)
The responses of my router after all that:
- flashing a "clean" bin directly causes bootloop.
- flash a merged bin causes a "steady on light", and just that.
- flashing github solutions didn't work, bootloop again...
I've not opened my router (i plan to do this if really necessary) but i can assure its a ArcherC20W V5 brisp cause the box are in PT-BR lang. I dont think that info would help cause there's no logs, but i can provide that info later (i might need help to provide).
Sorry if my English is confused or bad (i'm a self-taught trying to learn more), if my descriptions is consise i'm glad to receive any help if possible. Thanks to read.
