Same, I even go to Baidu and use Chinese keyword to search "ZTE MF680 固件".
But no result 
Lets hope the ZTE support team fast fast reply me la 

Guys is it proven that B04/05 firmware for ZTE MF680 cannot get purple light? I upgraded mine to B04 yesterday, I can't get purple light already but I still can get around 8mbps speed... But just doesn't feel right

This is wat everyone is lor lor luien about

[attachmentid=3063650]

Doing some testing on this software
psas.revskills.de

It was able to extract and flash it. Trying to figure out how it works

firmware thingy always risky, the worst case will end up 'bricking' the modem...

well at least i learn my lesson,..

for tweaking best get Huawei modem,.. 

will have to say R.I.P to my zte mf680 

mine is QPST_2.7_366 & qxdm 3.12.714 winxp

haiz, now need to search for new modem,..

well will hold on to this until end month and see how,.

just finger cross zte team reply,.

we might need to all email the zte team too.. then hope they will reply faster 

You guys are pathetic sial.

Take care and hopefully your modems are revived. I thought U Mobile's firmware was stable and great.

Luckily I'm always with Huawei modems.

the number u give me

hopefully to hear from ZTE team soon about the B03 firmware,..

I rarely check firmware version but since you guys pointed here, one of my customers asked me to check.
So, I poked in my Maxis SIM card and I can see this:
Firmware version is BD_HI3GMF680V1.0.0B01
Software version: PCW_HI3GSEP 18EV 1.0.0.B03

The purple LED did turn on when I tried in my office just now.

I guess everything is OK? I saw B03.

Ok, got it.. If only I can press "Like" on your posts 

Later after change to new modem I will post my crappy speed.

Now using Huawei E173, max only can get around 4mbps.

Thanks 

y not just tell ZTE u have the ori ZTE not the rebranding?
or this model only sell through ISP?

ohh...still can use la...that good 
hahahaa...dont troll him la...pity his modem brand 

cannot downgrade ?

use old/stock firmware like huawei..first uninstall umobile dashboard, then install the stock dashboard and stock firmware...maybe will safe him get back his awesome speed

Sad case

I tried email ZTE China in a typical China Chinese style



No point email ZTE guys, their CS are too busy to handle this kind of case to find a FW for us  
Any one wanna try email the sweedish telco through sweedish?
