Hacking V2801F & TWCGPON657 to suite your ISP Fiber

Issue

GPON market is a mess, plus explicit OMCI cause ONU Stick did not work

With my issue:

• V2801F build quality is bad, firmware is good, manage to have an internet connection
• TWCGPON657 build quality is good, firmware is bad, when GPON Password is set, stick hang and CPU usage become 100%

Since we dont have source code, try mix and match binary between V2801F and TWCGPON657

Usage

• Please read FLASH_GETSET_INFO.md for how to configure, login, etc...
• Advance setting like duplicate ONT Info, read FLASH_GETSET_DEV.md
