portugues,brasil,,Hello I installed the OpenWrt firmware on my Archer C5w V4 with the TFTP program, but I wanted to go back to the original TP-Link firmware.
I have downloaded the two versions and Removed the first 512kb from the beginning, because the Hungary Version didnt allowed me to use the channels from 48 and above.
So there are two versions 1- Intermediária updated up to 2020-05-21 and 2- Final updated to 2020-05-07
I used that one for Colombia, because the other versions were not good as I mentioned Before, it works for Brasil too. Link Below. Use TFTP.

Hi Naveen,
Can you please help me. I want to install openwrt in tp link aracher c5 router provided by ACT network
Few basic questions. You are all coders / developers. I'm being an end-user who owns an Archer C5 V4 model.
-
I'm on stock TP Link firmware. Can I update to open-wrt or any other firmware from the direct "upgrade firmware" page of stock firmware? If yes, please share the link to the file which needs to be directly upgraded.
-
If the above question is NO, then re-direct me to link or multiple links where-in **** VERY DETAILED**** instructions (along with downloads) are given for doing the above activity of moving from stock firmware to custom firmware.
-
Open from OpenWRT, are there any other custom roms available for this router?
-
Is the above model part of Open WRT master roster list? If not, any ideas / practical thoughts when it would be? I'm not demanding, but, it will help me to decide whether to proceed with the upgrade (so that in future I'm assured of updates) or to replace the router.
Thank-you in anticipation, for your patience in responding and taking time off to help me understand.
Please refer to the link / URL above. Can I use any of the files given in the link to upgrade my device to OpenWrt? If yes, how....If possible, detailed approach, please. PLEASE!
Thanks-in advance.

Could you please help me
No. You'll need to use the firmware recovery procedure or a serial connection.
The instructions are here (
https://openwrt.org/toh/tp-link/archer_c5_v4#installation_via_tftp_recovery_mode). If they are not detailed enough, maybe you should avoid OpenWrt in C5v4 for now while the support for it is not merged.
I don't know and I never looked for it. OpenWrt is a requirement for me.
The device support is not merged. It requires an ethernet switch driver that is currently only used by mediatek target (https://github.com/openwrt/openwrt/pull/4178 derived from my PR). If that gets merged (or another driver variant), the C5v4 port would be a more classical process and easier to get merged. I'm working on this for years and there is no ETA. I think that, as more devices requires that same ethernet switch driver, it will eventually touch one of the developers with commit access.
So, before that, you'll either apply the patch yourself and built it locally or use one of the unofficial images distributed here. Most packages will work and you'll be able to update them from the project as there is no "device specific package". However, kernel fixes will require a new image built by yourself or others. Also, as you will use a slightly different kernel, opkg will blame you if you install a kmod package as dependency mismatches the expected kernel signature (but forcing it might work).
You can replace your C5v4 with OpenWrt but you'll have some difficulties during package install (kmods) and firmware updates. And wifi 2.5g performance is terrible. If you are not a dev or a tester, stick with the original firmware for now.

So I own a C5 V4 and was wanting to install openwrt on it.
What are the issues that it currently has , and can I get a link for the files as well.
Thanks
There is no new development.
I have one C5 V4 running 19.03 as my main router/wifi ap. The 2.4GHz radio is very bad - so I basically disabled it and use 5GHz radio only.
It is working fine for me.

What needs to be done in order to build 19.07.8 for Archer c5 v4?
You can use this patch in 19.07.8:
This patch is for master, but can be applied to the 19 branch....
Basically, the problem is with the Realtek Giga Switch driver that is not supported by Openwrt yet. We are working with Openwrt to include support for this chip.

Not really "working" but actually "waiting" for someone to review/reject/accept the PR
Hi guys, some information about firmware 21.02 for archer c5v4?? Thank’s.
We are still waiting for the someone to review/reject/accept the PR.
The Realtek Chip for the gigabit switch driver is not supported by Openwrt yet , all of us are waiting on it too.
If you want to install it now , the 2.4ghz radio wont work and only 5ghz is usable.
