I have a flip phone that doesn't really work in America too well, SM-G1650 galaxy folder 2. I read somewhere that you can hex edit the radio firmware for some qualcom chip devices to use some bands that arent being used. Does anybody know if there is a way to do it on my device, and if its doable for somebody who isn't really familiar with hex editing?

Kgr can you provide a link for that

Kgr you wrote that you read somewhere...

Jumptoheaven In This forum as well as others.

Jumptoheaven Any updates, do you understand it?

Kgr I don't claim to have any expertise in this... that thread mentions different things depending on the chip type. One of the later posts seems really intriguing for those who want a qin f21 pro with us bands, but aren't sure if its permitted to use files pulled from an f30.

Biden2020prez He knows about that, he's saying that it's not simple it's Halachically permissible to use those files since they're pulled from the F30, but if you can modify it yourself then that changes things.

Techgen Right so i want to modify it myself but i dont practically know how.

From a root adb shell you can probably dd partitions to sdcard and pull them that way. Maybe look for /dev/block/by-name/nvram

Kgr

darth How exactly.
