[Help] Correct way of flashing downgraded 623m

[kenth]

Hello symbianize brothers.
Can someone teach me how to correctly upgrade the firmware of 623m?

My 623m was downgraded via gp1.0.4 firmware then 622m firmware.

When I try to upgrade it again, it's either I am connected no browse, or I cannot connect to any live mac at all.

try to factory reset via telnet then check your default gateway to CMD type ipconfig or ipconfig/all..

Thanks,
1) At first I tried upgrading via webGUI, failed stuck at 25%. Reset button.

2) Factory reset via CMD then upgrade via webGUI. Still failed at 25%. Unplug/plug power adaptor.

3) Upgrade via WinSpreader, after 20 minutes, it feels like the upgrade won't ever complete. So I log in to webGUI (without powering off or factory reset or whatever). Then re-enable the TELNET. Then /factoryreset.sh via CMD.
I was shocked, the upgrade worked.

I was wrong, the upgrade did not worked. It was only partially flashed.
Now I have tried uploading firmware via GUI, I can connect to live mac. But no browse still.

I noticed there were two extra row line under my telephone. This is not present in any untouched 623m.

*****EDIT

cd /etc
cat default.cfg
rm default.cfg
sncfg commit
sncfg reload
/factoryreset.sh

I applied the above command, now I can't log in as admin to my webGUI.
I know the old untouched password, but it did not work.
