[chirp_users] UV-5R Firmware Upgrade Capabilities

The UV5R uses an MCU OTP (Microcontroller Unit, One Time Program) as the firmware chip.
This is done to keep the cost down.
The factory supplied Software can be upgraded as can CHIRP programming software, but the internal Firmware is, well, Firm. :-)

I am curious what the issues are with BFB251.

I am confused, you say that there are no upgrades for  the UV-5R
firmware, but I have asked this before and someone said they're
working on it.   We need to be able to upgrade the Ver. 251 that is
very buggy to Version 291.    I'm uncertain if this group will be able
to do this, or not.     I was just seeking clarification, from the
group.    I am seeking this ability to flash the firmware to 291
through other sources if possible too.   I have too many friends with
the old version of 251 that need to upgrade.
