WRT3200ACM change boot partition and reflash Linksys FW

[kiwiandy]

I have flashed 1.11.X (Built 20180908-0910 git@b652fe9f) into my WRT3200ACM and find that I am having some wifi issues, and would like to boot back to the Linksys firmware until maybe a more stable Gargolye version is available.

I have flashed 1.11 into one partition and have 1.10 in the other.

Is there anyway I can flash a Linksys FW into the other parttition ?

You can find the relevant instructions in the Openwrt Wiki
https://openwrt.org/toh/linksys/wrt_ac_ ... penwrt_oem

Essentially, you just "upgrade" to the OEM image without preserving your settings.

Awesome thanks Lantis...really appreciate your hard work on this... looking forward to the stable (with updated wifi drivers?) version of 1.11 !

ok, this is taking me a little out of my comfort zone.... I assume I follow the instructions on Flashing Firmware OPENWRT -> OEM on the page you linked ?
I can succesfully connect to my router using PuTTY and bring up the CLI.... but can someone help me what I need to enter for the Gargoyle Firmware, rather than the OPENWRT firmware that these instructions are written for?

OpenWrt >> OEM
Backup:

Flash:

If VLAN config was altered, it must be defaulted prior to flashing OpenSSH Config PuTTY Config
Revert vLAN:

LuCI

System → Backup/Flash Firmware → Flash New Firmware Image → Choose File
Select Linksys image [.img] (Linksys OEM Builds)

Untick Keep Settings, then select Flash Image
CLI OpenSSH Config PuTTY Config
BUILDS PRIOR TO ~MAY 2018: Flash must be forced, as OEM firmware uses a different checksum algorithm

Login to OpenWrt via SSH (DropBear / OpenSSH)
Linux/BSD: SSH client built in
Windows: Download PuTTY & PuTTY Profile
Putty Profile
Line 5: “HostName”=“root@192.168.1.1”
Line 6: “LogFileName”=“&Y.&M.&D-&T_putty.log”
Line 58: “PublicKeyFile”=“C:\\Path\\To\\PuTTY\\Key.ppk”
Merge profile into registry, open/reopen PuTTY, then load SSH.OpenWrt profile

Download/Upload firmware image to router
Download via SSH Terminal:
cd /tmp && opkg update && opkg install wget && wget <Image-Link>
– OR –
Upload via Client Machine Terminal:
scp -r -i "C:\OpenWrt.ppk" -2 -scp -P 22 "D:\Path\To\Firmware.img" root@192.168.1.1:/tmp
For PuTTY, change: scp to pscp -scp

-scp = force use of SCP protocol
-r = copy directories recursively
-i = private key file for user authentication
-2 = force use of particular SSH protocol version [2]
-p = connect to specified port

Ok that instruction isn't quite right. It makes a very simple problem overly complex.

All you need to do is follow this:
viewtopic.php?f=8&t=8505
to establish both an SCP and a SSH connection to the router.

Move the required linksys OEM image into the /tmp folder using WinSCP
Issue a sysupgrade over SSH:
sysupgrade -n -F /tmp/name-of-firmware-file.img
