My Galaxy A9 pro 9100 has a bug i believe.... It does not pick up 2g network unless really close to a tower and my connection to the cell company is not stable the signal fluctuates even though am standing at one place not moving. I guess its because of the Chinese version the modem or CSC files may have something to do with way how the phone searches or connects to a carrier network... Can someone help me please

Hi, My name is javier, I have bought one nexus 4 8Gb orange phone, but it is sim-unlocked so I can use my MVNO ( mobile virtual operator network) But I am unable to use 3G or WCDMA band in spain.
I Know here are some problems about MVNO and 4.3 and 4.4 and 4.4.2 Android versions, but my problem is not this one. On a Vodafone SIM Card, I am unable to get internet also on this unit. The rest of the phone works flawessly, but 3G does not. I am starting to think that GSM chip is broken. But Hey 2G Networks works well no signal lost, perfectly clear voice on dialing, and constant 20kb internet data speed. No matter is an MVNO or a real operator like Vodafone.
Searching the net, i came over this:
Nexus 4 Suffering from 3G and 4.ยท Upgrade
And for all of you that are not going to take a deep read, let me tell, that they say there is an error on 4.3 and newer Android framework and Radio Baseband version. So people get unconsistent 3G connection. Well mine is really consistent. No conection at all never. So I think this is not my problem, although I have tried a bunch of roms even all google ones, all basebands and a couple of sims from diferent company.
Anyway, a quick fix is quoted here: Quick 3G Fix But I do not understand what is this or what I am supposed to do with that. Can someone help me with this?
And, after that, I start to look at something more, like Sim Unlocking is snot well done and 3g Band is still locked. Havent tried it with Orange sim as I do not have any. Is there any secret menu where network locks are shown?
And moreover, How can I trace what is happening to my chip? If someone has made hybrid basebands to unlock 4G, there has to be a way to track what is happening to radio basebands while they are working...and perhaps, I can gather some good info to work with...
One more thing on *#*#4636#*#* menu, I can force WCDMA or GSM or the rest options, If I use Force WCDMA, I get signal lost for ever, If only GSM or WCDMA Preferred, it has signal but only gprs internet conection. This is with ONO (MVNO). But with Vodafone, I get HSPA Conection but no internet at all.
Really annoyed with this, hope someone is able to help me with this.
Thanks to all in advance.
Nobody? well i will try to find out myself.
Anyway I have started to know something about android tracking with logcat, and would like to know if there is any way to check all the traces of the modem to check if the chip is faulty or is a driver issue and i have to learn to modify it myself. Thanks.
Hello
I live in Romania and own a I9506 from other country and in some poor signal areas the phone loses signal and emergency calls only appears while other i9505 holds the signal from same carrier (Orange Romania).
I would like if someone would help with a few modems to try and see if there is a difference in the signal quality.
Thanks in advance

So ... it seems that this device lacks the support ... Pitty for a device this powerful ... Wil sell and buy something else
Well you can extract modems by yourself. Just download the software you want and extract it with 7zip.
We don't know what's you're on now.

Try and flash the modem from the nordic countries( http://www.sammobile.com/firmwares/3/?download=26191 ). I have the phone too, but i don,t have that problems with the signal, also orange Romania. I bought it from Sweden.
Just flashed the nordic rom... will post if it works or not. thanks all
Ok so the problem is this ... The phone does not connect to network on gsm mode ... if it's on auto lte/wcdma/gsm it works on wcdma. If i select gsm only it does not connect to network. On manual search it all goes ok finds all networks but when I sellect my carrier it says registering on network for about 3-5 mins and after that can't register to network error. On other phone it registers with edge speed.
What can I try ???
Hello,
I have a huge problem with my Galaxy S5 SM-G900F. I bought it abroad and when I used it for the first time in my country I saw, that there is a problem with 4G/WCDMA connection. When I put my sim card to the phone and set all the preferences in mobile connection menu to "Auto" there is no possibility to call or to recieve calls (even if i saw signal strength meter showing some marks). I can only recieve and making call when I set "only 2G" option and manually select my network. But signal is also very poor.
What I have checked yet:
1. Other sim also doesn't work good.
2. After *#06# i saw my IMEI and it is the same under the battery and on the box (doesn't start from "00") so i think that it is not missed (efs folder).
3. Change firmware with KIES and ODIN for the other version - no changes. Also flash some other "modem" files with Odin with no success in better signal.
4. When im on the free air the signal strength is even at maximum level, but immidiately after going to my house - there is no signal. I saw also, that when im in the city i can connect with 2G network (only), but when im on a village there is no signal at all (even 2G...)
Do you have any ideas what can be wrong? Is this hardware failure? Maybe something with antenna? What should I do before going to gsm service center? Maybe i should change kernel and try some of the custom roms?
Thank you for your help.
regards
Mario
