can use on ZTE mf100?

You can use the Qualcomm chipset tweak or hardware mod

how to check software? what the goodness of doing this tweaking?

walao first time found this kind of thread..

For MF100 it won't be so obvious considering the age of the modem

You gain signal boost and stability boost

show the uMobile MF680 firmware flash ma
hm.. maybe the "3" firmware too

Don't want later my PM full of flame

Another sifu in the making, keep up the good work, we gonna recommend the Admin to give you the Elite Tag soon, like what we done to Chuah.....

this is a really great guide, two big thumbs up!

Nice sharing..
Thumbs up! Thumbs up!

Thanks for the support guys

Added possible fix for MF680 DC lost issue

Blacktubi, the modify on first post of tx power to 26 is permanent on modem right even after tweak with computer and using modem on router? Effect stay after tweak unless we tweak it back again?

Yes, it is permanent until you reset it

In fact the mdma actually tweaking these value too, mdma is tweaking BAND_PREF for the band option

agree. Remember to list my name in the nomination list. Blacktubi very helpful and great knowledge too

Added on October 7, 2012, 8:46 pmbut the mdma didn't tweak the tx power right? Only able to tweak band frequency. Need to tweak the tx power to 26 and see any improvement. If not much then will tweak it back down.

mdma didn't touch any other values except BAND_PREF

You may backup the whole NV Items just in case, there's a tool for that

quite less confident to testing tweaking after the purple led issue will test kaw kaw. If there tweak can gain higher stability, also a bonus for me.

install a femtocell la bro, Maxis is selling them soon

If you want stability, play with TEMP TX LIN, increase it a bit but not too much
