[Q] 3G not working! - Optimus One, P500, V General

So a few days ago I posted on here about getting my Chinese bought LGP503 working with the android app store. Using the tips I got from people on here I successfully flashed it to the UK LGP500 firmware and presto the store worked great! However, later that day I realized my 3G here in China wasn't working anymore. At first I chalked it up to quake related internet problems we've been having but then I talked to other people whose 3G was working just fine.
So I figured there was something up with my firmware not being compatible with the 3G here. I know that China has some different internet 3G standards from time to time but I've had friends pop a Chinese SIM card into an American Blackberry or other Smart Phone and it work just fine. So following this logic I finally, through no easy process, found and flashed the US T-Mobile firmware. Flashed fine and booted up great but still no 3G. Does anyone have a clue about whats going on with this? I really don't want to flash firmware again if I don't have to and I'm having trouble even finding the Chinese firmware now (the guide doesn't want to work for the Chinese firmware), plus I really like the way the T-Mobile stuff is setup, good apps and all.
I'm on China Mobile in Hubei Provence, China if that helps anyone any!
Thanks in advance.

Try creating a new apn from one of ur friends 3g settings..

KOREAN SGS2 Rooting/Flashing Help Needed!

Hi guys.
So I have a my own a working SGS2 and I have flashed roms before.
I am in Canada on the Rogers network
My friend got his hands on a Korean SGS2. - I rooted it and flashed a rom for him (Cognition I think) and everything worked out fine. Now the problem, I stick a SIM in, and the phone has serious signal problems. Say I try to call someone, it would take over a minute to connect. Or when I try to use data, it doesn't work.
My friend actually took it some store. They guys at the store said they could make it work if the phone was back in its original korean firmware, which I can't find anywhere.
Any ideas?

[Q] jiayu g3 jy-g3

hi
i have bought a jiayu g3 from china. from pandawill.
i am having really bad problems getting the internet or gps to work properly using network. wifi is perfect and very fast.
i have tried so many different apn settings but nothing is working as it should.
gps only ever worked once after i left it going for about half an hour but then i moved and it gave up again.
i changed from giff gaff( o2 ) and am now using virgin (t-mobile and orange). no better.
while i was at work i turned 3g off and the internet worked on face book but not accu weather or ebay or mail. i have turned it off and on again but nothing at all now.
as a phone and while using wifi its a lovely phone and would be over the moon if i could get it working as it should before i give up and put a hammer to it. ive had it for about 6 weeks now and this is driving me potty searching and trying new things to no avail.
i was thinking of sending it to someone on ebay to root it but i dont know if that is the answer.
it is running android 4.0.4
its dual sim and i am using the "w" slot.
getting despondent now.....
any ideas will be gratefully received.
thanks
also, how do i get a signature on here so i can put my phone details on?
i had a desire s previously and the internet and gps was fantastic so i know its not an area thing.

[Q] AT&T One X + Tethering with International SIM

Hey guys,
So I have a bit of a tricky question that I can't seem to find an answer for. My wife and I just move to Europe for work for 2 years. We had AT&T in the states, so my wife has an AT&T HTC One X+. We got our phones SIM unlocked before we left, and purchased French SIM cards that run on the Bouygues Telecom network. My phone (Lumia 925) can do wifi tethering no problem... My wife's on the other hand has issues. I keep getting the following error:
" There is a temporary network problem that prevents the enablement of the Mobile Hotspot function. Please retry later."
I have tried the following steps:
1. Rooting the phone.
2. Installing other hotspot apps (Both root and non-root)
3. Installed custom ROMs with hotfixes to remove AT&T data requirements.
I don't know if it's relevant, but when I do a reset on the phone, it doesn't automatically connect to Bouygues network for data. I have to manually add the APN every time. Once I do that, her mobile data works just fine, so I don't THINK that the APN is causing the problem...
Anyways, if anyone has an suggestions on how to fix this issue, I would be indebted to you... I've just never encountered this problem on any of my other Android devices and I have to believe that there is a simple solution to fix the problem that I've just not encountered. Thanks!!
I loved my international HOX, so when got dropped in water i said lets go for the ATT HOX+ that has LTE.
Big mistake! I have OP's same issue, im in spain and my provider is Movistar.
I bought it on e-Bay, configured all the APNs, I used settings from their webpage and also tried telephony.db values from an international rom, stock rom didn't tether.
Rooted stock (4.1.2 i think it was) still nothing.
Elegancia (4.2.2) ROM, still nothing.
Changed some stuff on the telephony.db, still nothing
Swapped the wifirouter.apk with the international wifirouter.apk, still nothing.
Nuked TetherGuard.apk, still nothing.
Installed Moto-X tether Xposed module, still nothing (probably cause it's for android 4.4).
I read that AOSP or Cyanogen ROMs don’t have this issue.
I also read that if you swap telephone.db from international version to USA version the phone goes into a reboot loop, [More Info].
I guess the solution lays in something similar to the Moto-X tether patch, but i don't really have the time to fork the project, and try to get my tethering working.
Hope someone can give us a hand, im sure there are at least 5 more people in this same situation.

unstable signal and nothin I tried worked til now

I bought sprint Galaxy Note 3 unlocked from ebay India. Everyrhing work great in it but one problem and the biggest problem which can't be cured is UNSTABLE SIGNAL. Signal falls from full to no service and again gain network.
Did everything I can. Updated with latest stock rom, which automativally updates bootloader and modem.
Factory reset, cleaning and all, flashing new rom, changing to New Sim and trying every network Sim available.
There is nothing under the sun I didn't do.
I used this phone for a month without Sim and it worked normally without getting overheated. And I speak and chat on social sites like whatsap, Skype and it's works fine.
What is the real problem? Radio band compatability? Hardware? Antenna compatability?
I don't know what but this is the best phone I have ever used. If I can fix it, I would be the happiest one.
Please someone help.

Data Connection Partially Lost on Unlocked Sprint M9 after Official Nougat Update

Hi all, sim unlocked s-off sprint m9 used to work well on android 6 with official rom. But until the phone was upgraded to Android 7. Data connection stopped working for one operator (NOS in Portugal). However Vodafone works well.
Tried different roms and apn settings, same at all. Data connection does not work on NOS operator.
Does anyone have similar issue and of course any advices?
Thank you all.

Why sim unlock a Sprint variant and not an AT&T or T-Mobile which already support GSM?
did you find a solution?
i have exact same issue.
bought one m9 from ebay with sprint (651) firmware on.
lte was working fine in israel (1800 2100).
after nougat im only getting 3g.
it makes sense that i cant use those bands (1 and 3 i think) on a sprint device.. but it did work with marshmallow
Same problem in the USA
I have (nearly) the same problem in the United States with a Sprint CDMA version of the One M9. The main difference is that my data speed is even worse than 3G, around 10-20 Kbps. Occasionally, I get faster speeds, but I haven't been able to figure out if it is location-specific (but always away from home and work) or due to some other characteristic.
The phone came brand new in a retail box from an eBay seller. It worked as expected for 1.7 years. The OTA update which installed Android 7 (aka Nougat) in early 2017 resulted in the very slow data speeds. WiFi is unaffected, but data is so slow that I cannot reliably send or receive MMS; Google Maps says that I do not even have a data connection for traffic info.
EcoMobile (my MVNO provider; I still have a sprint email address, so I know who is actually providing service) could only suggest resetting my phone; did this twice with no change in operation (but several of the programs which automatically re-installed themselves operated differently, including GMail no longer providing auto-complete for addresses).
After literally 2 hours in chat with htc, they told me that my MEID indicates my phone was "made in Taiwan". I took this to mean that: 1) the person I was chatting with had poor English skills (because aren't they all made in Taiwan?), and 2) my phone is gray market (meaning it was not imported into the country via official channels, even though the manual was in the American version of English).
I came to XDA looking for an answer, too. I was mildly surprised to see that this topic was at the top of the list for the One M9.
The best solution for my situation would be the proper ROM for my phone, but I don't know how to figure that out from the MEID. htc USA says they cannot help me with this.
I could even go back to Android 6, but I do rather like the new features in Nougat.
Alternatively, I could root the phone and install a 3rd party ROM, but I still need to know how to choose the proper one for my phone.
I hope this info finds its way to a helpful expert.
Regards,
Jeff
