I've never downgraded.@meritez would you know please?
Thanks,I've never downgraded.
I've heard of people downgrading to B02 using the Nordic framework as the B02 modem firmware is in the framework.
To get B04 modem firmware you would need an mtd backup from someone who has serial tftp wrote Openwrt without ever touching the modem firmware.
What issues are you facing with B12?
You using external antenna?Thanks,
I had issues connecting to Vodafone 4G Band7, it was only stuck at 3G and no internet. I have seen it doing Band1+20 CA in another area on Vodafone.
This made me think it could be due to different CA setup in the original 3 modem firmware.

Yeah, I wanted to keep the look of the router as stock so made it like this. Not sure if you have seen my UART mod threadMost mf286d serial mods go out the side of the casing that the UART connection is located.
Yes you even link to the photos of the serial mod out the side of the case on the Openwrt wiki.Yeah, I wanted to keep the look of the router as stock so made it like this. Not sure if you have seen my UART mod thread
ZTE MF286D permanent UART Mod
Hi all, I came across ZTE MF286D idea on this forum and was really helpful. I ordered MF286D on Ebay for £39.99 which was supposed to be Grade C but was practically unused.
