Great. Did you flash the radio baseband from the 30O update? What telco are you using btw? I think my signal dropping issue has been fix!!

Signal bar still goes out and Signal strength is still at 0dBm 99asu when i'm in the office. Service state is showing as "In Service" but I cant receive or make calls.

Mind to share which telco you're using? And your sim is 64k or 128k?thanks
Hey, you're not alone. We're both pretty much sKrewd in this case (hehe sorry I just can't help it).
I'm using celcom. And when I put my sim on other phones, it'll always get at least 3G or H. But with OPO, it'll always be Edge. I'll only get 3G or H if I'm outside of my house. But even when I drive around KL, my OPO seems to prefer Edge even when I've selected LTE in the network settings.
And yes, I've tried all the suggested fixes I could find in here, xda and OPO forum. I'm not too sure how long I can live like this. I haven't tried other telco, coz all my family is using celcom.

me too, mate. i have checked and searched everyday all over the net, trying out new "fixes" to no avail. tried the modem fix, flashed PA, still nothing. my gf with her 64gb OPO (also on maxis) doesnt seem to have this issue. i've yet to try another network as well. thing is, i didnt have this issue with my lowly moto g.

Both unit china version? I tried searching your previous post but you didn't mention. In your case, since both of you are using maxis, with the same phone (I assume both OPO is china version), have you looked at the sim card?
1. What are the similarities or differences between the two sim?
2. And how about you try to put your own sim in her OPO?
If let's say when you put in your sim in her phone and the problem appears, then maybe you need to change your sim with the same type as hers. (I mean in terms of 64k or 128k chip, if it does make a difference). This theory would prove to be more plausible if you insert her sim in your OPO, and the problem disappears.
I'm sorry if what I'm saying doesn't make any sense at all.
Thanks for your suggestions. I'll keep in mind as a last resort options. =)
If that's the case, I suggest you to just simply flash the whole ROM again. You still can access custom recovery right? Good luck.

yes, both are china units.
i kinda ruled the sim thing out because we both replaced our sim cards with the same (afaik, we replaced them from the same branch at the same time) maxis 4g sim cards a week after getting the phones.
i'll try your second suggestion later and post an update.
Ah. the radio baseband flashing didn't work for you guys? Peculiar. i kinda ruled the sim thing out because we both replaced our sim cards with the same (afaik, we replaced them from the same branch at the same time) maxis 4g sim cards a week after getting the phones.

Lowyard's case seems like working but bad connectivity while sKrewd doesn't have a good line at all. As you've said, it's good to try out other people's sim card for now.
I'm using Digi and calls and network are A OK after I flashed mine. It was just the dropped calls from LTE/3G mode that were the problem for me.
