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, died from overheating, 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
|
|
|
|
> Update:
|
|
>
|
|
> V2801F firmware can be used on TWCGPON657 stick. However, Stick will keep rebooting due to invalid `VS_AUTH_KEY`, read **Auto Reboot Fix** below

# Auto Reboot Fix
|
|
## V2801F
|
|
### Problem
|
|
* Invalid `VS_AUTH_KEY` can cause auto reboot
|
|
* Changing MAC Address `ELAN_MAC_ADDR` can cause invalid `VS_AUTH_KEY`
|
|
|
|
### Fix
|
|
* You need to generate new `VS_AUTH_KEY` when change `ELAN_MAC_ADDR`
|
|
* Apperently, you have few seconds to access Telnet before rebooting, if you can't type fast enough, use this autoit script `quick_telnet-login.au3`.
|
|
* To prevent auto reboot by entering `echo 3 > /proc/fiber_mode` (XPON Ethernet Mode)
|
|
|
|
### Note
|
|
When `echo 3 > /proc/fiber_mode` is set, you lose telnet acccess, you need to unplug fiber to get back
|
|
|
|
##TWCGPON657
|
|
* No such problem, `VS_AUTH_KEY` does not exist.
|
|
|
|
# Usage
|
|
* Please read [FLASH_GETSET_INFO.md](Docs/FLASH_GETSET_INFO.md) for how to configure, login, etc...
|
|
* Advance setting like duplicate ONT Info, read [FLASH_GETSET_DEV.md](Docs/FLASH_GETSET_DEV.md)
|
|
|
|
# Modify
|
|
You need a Linux PC/VM, Ubuntu as Operating System
|
|
|
|
## Prerequisite
|
|
You need these program installed:
|
|
* `tar` (extract tar package)
|
|
* `squashfs-tools` (extract/repack rootfs)
|
|
* `qemu-user-static` (run MIPS VM)
|
|
|
|
## Extract firmware
|
|
* Extract Firmware package in `tar` format, we need `rootfs` file
|
|
* Extract `rootfs` partition
|
|
```
|
|
unsquashfs rootfs
|
|
```
|
|
|
|
## Repack firmware
|
|
* Repack `rootfs`
|
|
```
|
|
mksquashfs squashfs-root rootfs.new -b 131072 -comp lzma
|
|
```
|
|
* Rename `rootfs`
|
|
```
|
|
mv rootfs rootfs.old
|
|
mv rootfs.new rootfs
|
|
```
|
|
* Update `md5sum`
|
|
```
|
|
md5sum fwu.sh rootfs uImage fwu_ver > md5.txt
|
|
```
|
|
* tar current folder
|
|
```
|
|
tar -cvf ../firmware.tar *
|
|
```
