OpenWrt installation on F9J1108v1

Installing and Using OpenWrt
1

I'm trying to install r22 on a UK F9J1108v1 device and cannot flash kernel part because the uBoot expecting a special header, neither eDiMaX nor eDiMaXsUpEr nor F9K1119v1, it looks like

could please someone extract me uBoot binary image (/dev/mtd0) from a F9K1115v2 or F9J1108V2 device? I believe then I can replace my uBoot version and flash a factory image...
thanks in advance, Slava

for flashing the F9k1108V2/V1 use the factory file
"openwrt-22.03.3-ath79-generic-belkin_f9j1108-v2-squashfs-factory.bin"
sysupgrade didn't work between ar71xx and ath79
you have to use the factory recover

hold down reset button while booting
use fixed ip on pc local to 192.168.2.1 say 192.168.2.2
and use web page at 192.168.2.1 to upload Factory file

https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=b403a6e1241c00f509b201ec2ac8ca5f29e1ffd1

if you still need UBOOT
http://luckys.onmypc.net/openwrt/Belkin%20F9J1108V2/OpenWrt.mtd0.bin

it doesn't work, any openwrt files are rejected by this web loader

I've stripped the factory.bin up to magic number and uploaded by tftpboot, but the kernel can't be uncompressed:

do you have a belkin factoy image that works ?
to compare header ?

ps added uboot to last message you may have missed it

the version i have installed is

Hostname F9J1108v2
Model Belkin F9J1108 v2 (AC1750 DB Wi-Fi)
Architecture Qualcomm Atheros QCA9558 ver 1 rev 0
Target Platform ath79/generic
Firmware Version OpenWrt 22.03.2 r19803-9a599fee93 / LuCI openwrt-22.03 branch git-22.288.45147-96ec0cd

unfortunately no, I've replaced it with openwrt-15.05.1-ar71xx-generic-f9k1115v2-squashfs-sysupgrade.bin, it does work with Belkin original kernel Linux-4.9.243

I can also replace only the rootfs from 0x9f050000 and it boots OK but only till r18, the later releases arn't jffs2 compatible

8

the memory layout was completely changed for ath79
the kernel location is different with a fake peace of code to jump to the new location
to make use of all of the memory
I have never need to use tftp on this so it may not work with new layout

just in case you changed uboot variables

no differences between your and my bootloader :frowning:

10

no differencies in my and yours uboot_env either...

11

could you please export mtd0-mtd8? so I would be able to boot into r18 and reflash them all
how does your /proc/mtd look like?..

sorry have to go out but will look more tonight
