I really had problem opening the casing of my MF680..Got stuck opening the back case,the one beside the sim tray..For the front panel I see there's 3 screws there..

Someone can help me on the right way to crack it open?

thanks bro chuahcs but I've already seen this and a few times also..The thing is that it is an assembly not a disassembly video and at the second he tried to put the piece on,he take it up all over the camera so I couldn't see..I tried pulling it up but I already did that sometime ago with another device and the clip broke..So I really2 wanted to know the real way open it,without breaking the clips that is..Say like pulling it up but towards the edge,or from the sides..Thanks

i can make a video tutor on how to open zte mf680 for you to refer,

i try to make better video than his when remove the cover,..

Thank you very much. I would gladly accept that.

here is my own video tutor,

hope it helps you out,.

the front cover i did try to run the modem without it, but signal& Speed drop tremendously if the silver thingy on front cover didnt touch the small gold piece on front board ( it is act as second internal antenna )

No, i am not

i am still learning just like everyone else,

remember front cover cannot remove, otherwise the silver thing didnt touch the board, you will suffer signal & speed

Thanks for the tip.Thanks a lot.

i still trying to figure out how to make the silver thing stick on board without the front cover

nice info

@TS nice thread

Updated latest dashboard UTPS V23

hey blacktubi,do u know if AT commands can be use to set freq?

I am not very sure about this unfortunately

Was researching for quite a moment but no result

same here.. seems like it acts like modeswitch only...

i remember i do recall one websites have those old AT command,.

but i seems cant find the webpages,

i found 1 doc.. huawei umts at commands interface.. seems like we can relay an AT commands to set specific frequency on our modem.. but.. dunno if openwrt chatscripts supports it or not..

Hi blacktubi, i have to say this is by far the best wiki for our local 3G, where all info that consumers need most are compiled together.. I just have 2 suggestions here:

1. In your very first post you mentioned DC-HSPA+ is MIMO.. Yes generally MIMO is part of DC-HSPA+, but none of our 3G providers have actually activated this. The 42Mbps is acvhievable with 64QAM modulation and dual carrier only (as compared with HSPA 14Mbps). With MIMO and DC, the peak would be 84Mbps

2. Although Maxis has several APN, i think they have implemented dynamic APN for quite long, which means no matter what APN the user puts, the network will decide and route which APN you should have. Not 100% sure though..

1) Yes, this is my mistake. Initially I got some misconception in MIMO and Dual Cell. Just realize recently after further my research in UMTS 3GPP.

2） Yes, Maxis did actually implemented dynamic APN for postpaid broadband and mobile internet. I can even connect with 'blacktubi' as APN. Just sometime most beginner users prefer to set a APN instead. Or I should say placebo effect.
Some plan like the old SKMM require 'bbnet' to be as APN. Therefore I keep this info there

Thanks for all these information
