The modem was on b12 and flashing b11 caused it to report as b02 SVN 12 however turning it off at power for half a minute then delta flashing b02 to b05 worked using at commands and adb push on openwrt. The power off for half a minute thing was fairly important. It then returned b05 SVN 05 so I delta flashed up to 11 then nand erase and reinstall root_uimage Nordic on the router side. That still failed the b11 to B12 fota update on Nordic web login so framework Nordic to Nordic which the router was happy with as it could see the router was now on Nordic so that synchronised it all back to b02.
Then I did the tried and tested fota upgrade process from b02 up to b12 and it was fine.
What I've learned from all of this is the simplest, most reliable and safest way to upgrade is open it up and spend a couple of pounds on a serial interface, framework from stock to Nordic which will put it on router b11 and modem b02, then framework Nordic to Nordic which will put router and modem on B02 so they're in sync, then from a serial terminal extract the web password and set the fake temp IMEI to Nordic variant for flashing fota b02 to b05, and b05 to b06, then faking not needed after this point so the terminal can be disconnected and fota it up to b12 (which has all been described earlier on this thread).
Trying to update without opening it sounds like a good idea but it so isn't worth it. I've lost literally hours trying that and soft bricked the router twice. There are some very helpful people but language is a barrier as most of the help is in Polish or Italian language, Google translate is good but it doesn't help searching for terms in English when searching those forums. I'm pleased to have the router back up and running now. The other consideration is openwrt isn't ready for this device, I would consider all versions to be treated as bleeding edge. The way qmi is handled on wrt is unstable, I could set my clock to it going from fast to snail speed each evening in line with congestion, stock Three and Nordic deals with this without any problems. WRT looks good but in reality I am getting better speeds with consistency and reliability using Nordic over wrt. I live around 1.2km line of sight from the mobile tower and usually get speeds at the very least 65mbps, usually 75-80mbps, occasionally peaking just over 90.
