can we just use the gui firmware upgrade page from original asus firmware and use the above file, if we want to change from asus firmware to openwrt? or do the only way to do it is what follow the guide from the device page?
Follow the Guide First!
Let's have this here as reference pulled from the url you listed in the OP.
Sorry for being a noon
Installing OpenWrt via TFTP is basically same as this https://www.youtube.com/watch?v=rtrMpANC2kk?
I know you want the correct instruction set, and I would like to help. I think it would be prudent to double check your unit for any revision numbers printed on the case..
There are a few threads that distinguish between methods of install. The revision printed on your device is the most IMPORTANT bit of information needed before proceeding toward any method.
So please double check your model number with revision and post back.
From the sticker at the back, the only thing i could see mac/S/N is H/W ver B1
Assuming all the data you've written in the title is correct the directions from the Git commit of this device is similar to the device I've listed.
Here are the detailed instructions from the git
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=87c42101cfb001b4bd418d1201fa4d8c822dc77b
This is the device listed in your title.
I got to the Git Commit by looking down a few lines in the link above:
"Supported Since Commit"
This method is very challenging. I've never had to do a serial install and can speak no further on what your challenges may be.
This is the forum search for your device, you should spend some time seeking out clues and members to recruit into your initial flashing for encouragement and direction.
I wish you the best friend.
from https://openwrt.org/toh/hwdata/asus/asus_rt-ac1300uhp page
under Comment installation: Identical hardware to RT-AC58U, follow same directions
if you open https://openwrt.org/toh/asus/rt-ac58u it says you need to open the modem
but from https://openwrt.org/toh/hwdata/asus/asus_rt-ac58u
there is a link saying https://openwrt.org/docs/guide-user/installation/installation_methods/tftp_generic
which points to https://openwrt.org/docs/guide-user/installation/generic.flashing.tftp
that's why i asked if this method is valid rather than using the serial that you'll need to open the modem
then the generic tftp method is basically same as this https://www.youtube.com/watch?v=rtrMpANC2kk right?
Good job on the linking, it was very succinct.
Bilbo thinks about that for a moment and then confides to Elrond, “And i’ve heard that it’s unwise to seek the counsel of elves, for they will answer both yes and no.”
No: in the documentation above, nowhere is it mentioned that using a TFTP method on Youtube.
Yes: The closest it comes for two of the models is the easy method. Which from what I've read is using a custom built, user hosted OpenWrt variant. Read that thread.
Hi,did you succeed?58u and 1300uhp are use the same procedure?page seems just for 58u?
