Hello i have rb951u2hnd with openwrt 19.0.7
today i decided to upgrade it to openwrt-22.03.2-ath79-mikrotik-mikrotik_routerboard-951ui-2nd-initramfs-kernel version.
but when i want upgrade from luci it said that you need force upgrade > ok i did it but i cannot access modem...so i again flashed it with 19.0.7 .elf file.
how i can upgrade it to 22.03.2 without issue?
Don't use the initramfs, to start with.
What modem?

I have the same problem. What should I do?
If I am not supposed to use initrams, how do I install sysupgrade?
You are supposed to use initramfs, but only temporary.
I did the same thing with firmware 19.07.10 (elf) and sysupgrade flashed successfully. The only thing is that there was no NAND error and I didn't have to do a "Force upgrade".
Screenshots below. Step by step:
I tried flashing with factory firmware 6.48.6. (long term), the result is the same. That's why I'm trying with Stable version.
This red warning was not present on firmware 19.07.10.
There was no forced update either.
After all these actions, a little time passes, the router reboots and...Reboots again. Again and again.
