Hey guys i need your help. I been flashing lots of roms for the past year. all of a sudden playing with the newer roms last night.
i went to speedteam eclair
http://forum.xda-developers.com/showthread.php?t=691445
didnt show time and didnt like it..so went to something more stable in cyanogen
http://forum.xda-developers.com/showthread.php?t=688262
Then all of a sudden today my cell doesnt get any more NETWORK CONNECTION , no 3g , no reception, i checked the apn, search network connections...Nothing
found out its the sim card...swapped it with my other nexus one phone and indeed its the simcard...
so i guess new question is what went wrong with my simcard?
Over the last three weeks something has happened which has caused my phone to permanently keep an HSDPA connection to the network. Previously I would get the 3G symbol when mobile data was enabled, and then the H would appear only when actually transferring data. Now the H is there all the time. Even if I turn off mobile data the HSDPA connection is still there (verified from the Phone Info screen) even though neither H or 3G are displayed. This is playing absolute havoc with the battery life of my phone.
I'm strongly suspecting that something has changed at my provider's end (Vodafone in Australia) as they are actively upgrading the network in my area. I have also travelled elsewhere and seen the old behaviour, so I'm pretty sure it's not my phone. But I'm still wondering if there's not some setting I can change which might restore this type of behaviour, say in build.prop. I am running CM7 on an HTC Desire. I've tried a few different radios but none changed this behaviour. I'm currently using 5.17.05.23.
UPDATE: I have noticed that I have only no 2G service. What am I doing wrong? From *#*#*4696#*#* under phone info I have enabled "WCDMA preferred". Can this be a hardware thing if I have 3G connectivity but cant connect to 2G network??
Hi everyone!
I've been having a strange problem lately - at random times and random places I suddenly have no service so i can make no calls. Then after about 10 minutes I have service again and everything seems to be just fine until the next time that happens.
This can happen at random places but also after I return from somewhere where there's not supposed to be any service (from the basement for example) it also takes very long (10-20 min) until I have service again. Also i have noticed that sometimes when I have no bars and can make no calls, I can still go online on mobile internet (not wifi).
It started after I updated Hyperdroid 2.01 to Hyperdroid 3.0. I have since then tried several times to completely wipe everything (have reinstalled WM6.5 (the problem persisted in WM6.5 also) and have wiped everything with task29.
After wiping I have reinstalled radio v 2.15.xx, MAGLDR 1.13, CWR 150MB partition and then reinstalled Hyperdroid 2.01 but i still keep getting the random service drops.
Can this be hardware-related? What else can I try?
"What else can I try?"
Your sim in another phone. Not just for 5 minutes, for a few hours.
Have you looked into your providers network status? Could be doing system upgrades.
Have you inadvertently set to use 3g only?
I didn't know that there was an option to only use 3G. But as soon as I switched to "only 2G" I lost the connection again so it might have something to do with that. How could I disable this "only 3G" (I can't find it near the "only 2G" option).
Also will try a different sim.
Thanks

sorry, not sure offhand, i used to know how to do it in winmo.
So now I have tried dialing *#*#*4696#*#* to enter "phone information" and there ir reads "WCDMA preferred" so that means 2G should be enabled as well. But when I select GSM only i dont have any service and under DATA it reads "fail because Radio Not Available". I have 2.15.xx radio rom installed, also tried 2.12.
Did your tryed to flash a other kernel?
I did. But the same kernel worked for me about a week before so this cant be it right?
Can this be a hardware thing if I have 3G connectivity but cant connect to 2G network??
thats not a hardware issue, sounds like a Rom problem. Test out the radios, and see which one gives you the best signal
I have tried different radios (2.08, 2.10, 2.15) different android roms (Hyperdroid 1.04, 2.01, 3.0, 5.30, MIUI gingerbread) and different WM6,5 roms. I have tried switching SIM cards. I have tried switching off ond on data connection. Have tried switching 2G/3G to 3G only and to 2G only. Nothing helps. I still get no service when I am in a 2G only service area.
Please help. Anybody?
finally, somebody with a same problem as me... i have tried to fix it for 6 month, and still can't get any 3g signal, i have tried task 29, wm 6.5, different android nand and sd rom.
but the 3g signal showed in wp7 rom, have you tried wp7?
I have not. Maybe I will. But my problem is that I don't have 2G signal - I do have good 3G signal though.
Tried to install Windows phone 7. No luck. Still no 2G signal. What does anybody think of this http://forum.xda-developers.com/showthread.php?t=1190180?

I'm the opposite, but did you able to browse mobile internet with the no signal?? If you can, and get 2g speed then it's not the hardware, as your phone still able to get 2g signal
Sometimes my phone can browse the net in 3g speed even with no signal, so i guess its a software problem??
Two or three times I have had G or E instead of H or 3G in the notification bar but although it shows me that it has service it wont connect to the internet neither can i take calls during that time. All the time that I have 3G or H connection i can take calls and I havent noticed that internet would be slow.
So I have almost given up hope. I have quite good 3G service where I live but still 3G is not that strong indoors and I have too much downtime so my next desperate step would be to open up my phone and see if I can find something wrong with the connectors.. I really dont want to do that..
Hi everyone !
Lately I went to a place were 3G/4G was not reachable and it is there that i noticed that my brand new Moto X play couldn't get any connection in 2G (GSM) mode even if the place was fully covered with 2G/EDGE (GSM)...
In 3G/4G there is no problem only on 2G (GSM).
I tried in the settings to put 2G (GSM) only and I can not get any signal even now that i'm back home ....
I tried a factory reset from the recovery it did not work :crying: Do you have an idea on how to solve that problem ?
I also tried to use the sim card with another phone in 2G (GSM) and there it works fine with maximal signal ....
Thanks ! :laugh:
Hallo,
I did a test and I got the same "problem".
Turned 4G into 3G...no problem.Still connected..
Turned 3G into 2G....no signal.
Turned 4G into 2G..no signal.
You can try to switch networktype in *#*#4636#*#*
No time for me now....I will try it later on the day.

I just tried it and turned the networktype to "GSM only" then i got no signal just like before. If i try to use another type like CDMA/GSM it connects to 3G and works but still the problem with the GSM/2G....
Hi guys. I'm not experiencing this problem on my XT1562. switching between bands is fine and working on my device. What kernels are you guys using?
I'm using the stock kernel, I just flashed the OTA (6.0.1) from the stock recovery
Same Problem, more information
For my Moto Play X I have a very similar problem:
4G works, but 3G and 2G do not. If I'm connected to a 4G network, I see that there is reception and can use all data transfer functions. But when I want to do a call, I get a timeout. When I'm in a place where there is no 4G network available, I see that I don't have signal - but the network is shown in the list of available networks for manual selection.
As I have a dual SIM variant (stock ROM, not a custom modification or "upgrade") my second SIM does work like a charm. I tried now and swapped the SIMs - and it seems that just the SIM1 slot is having those problems. The same SIM also works perfectly in the second SIM slot.
I also tries to reset just the network settings (an option provided by the stock ROM) but this didn't change anything.
Next step I'm currently working on is doing a factory reset - will take a while until backup and restore will enable me to see the real result. I'll keep you up to date....
UPDATE: factory reset didn't change anything - will send phone to repair now. :,-(
Hi,
did anyone using Umi Super have any problems with using 4G at 800MHz? Im on giffgaff and even though Umi Super is supposed to work at 4G under 800MHz (thats what the specification states) i cant manage to make it work. I have perfect 4G coverage, 4G sim, 4G tariff, even gave my sim to a friend with S7 edge and it worked on his phone. Maybe new update will fix that? I tried with different sim from different operator (LYCA) and it works but 4G in LYCA is at 2100MHz so I didnt really check the 800. I tried everything and still nothing. Did anyone have similar problem?
I actually bought 2 phones of the same model so I decided to check if 4G worked on the other one and as I put the sim card in I just remembered something and realized same thing happened with my phone. When I put the SIM card in for the first time it DID automatically go to 4G, ok, when I looked for available networks it found O2 4G, granted BUT!!! when i got to "preferred network type" there is only 3G to pick, and THE MOMENT I PICK IT there is not possible to go back. Every network I find from that moment is only 2G or 3G. Now i reckon that a software problem right? See attachments
It is a software bug and I think I sort it out after flashing the phone. For now I sorted out the problem using Networks app by Philipp Mangalov and switching network to LTE/GSM auto
Well it seems the data part of the UMI SUPER is not so super, is it? I face a similar problem but worse. The 4G band of 800 doesn't work(despite being advertized by UMI as supported) but luckily the band of 2100 works without any issues. The problem comes when I'm out of 2100 band coverage and phone must switch to 3G - then I lose all data connectivity completely. So basically whenever I'm out of 4G 2100 coverage(which is often) I am without any connectivity! Anyone facing the same? Solution?

I only have 3G and the phone shows that I have internet, but when I try to actually use the data it just says no connection on apps.

I don't have this issue at all. My UMi Super connects perfectly to my 4g network under 800MHz without an issue here in Uganda. You can install the MTK Engineering app from the play store and check the band compatibility on ur device and you can also set the mode using the same app under android settings.
You could also try updating to the latest OTA which is 20160810 or the one before it by downloading the files from forum post here and saving them to ur phone and updating manually if you don't have the current OTA

GravityBox is a perfect solution for this problem. You can set up an icon in notification bar allowing You to toggle between 2G/3G/4G

same problem
This is indeed a software issue, one I have come accross many times - using an app to toggle between the service types is the best workaround!
There are many apps that work to resolve this, some great ones have already been mentioned.

4g Umi Super on Giff Gaff
You need Giff Gaff settings in access point name. If you try and use O2 4g it doesn't work even though Giff Gaff uses O2 network. Settings are really easy to input but MUST be Giff Gaff not O2.

All that's needed is GiffGaff settings inputing manually. Very easy to do. O2 settings that the phone recognises when a GiffGaff sim is used WILL NOT WORK. The Network is O2 but the APN settings for GiffGaff are totally different.
All you guys that think you know what you're doing obviously don't.
No need to Root or use GravityBox or any other App.

Well said. I just shake my head in despair when I see how totally clueless people try to be teachers and Internet gurus with very limited knowledge about the task at hand. These comments should come with warning stickers.
For those who want to be able to switch between 3G/4G and LTE only, use this nifty little APK that I've attached below. It will allow you to enter engineer mode without using the dial code.
Hi
This is a bug implemented in Android 7.0.
I had the same.
1 Just force in your parameters 2G/3G networks
2 wait for network authentification (no more excalamtion mark)
3 go back to 4G
Every thing will be OK to next switch off or plane mode.
Rgds,
LTE band 7 (2600) not working
I recently received my new Umi Super and updated to the last firmware V7.01_20170413, everything works fine except for the 4G. I live in an area where band 7 (2600) is available but the phone can't connect to it. Of course, my preferred network type is set to 4G/3G/2G (auto).
I read a lot about the issue on the internet but I can't find a solution.
I checked the BandMode on the phone by dialing *#*#3646633#*#*, band 7 is included and checked. However, when I tried to remove the other LTE bands and keep only band 7, I got a message explaining that the list can't be empty ("Failed. The band is changed from not null to null, it is illegal"), though the list was not completely empty because band 7 was still selected.
Also, I tried to change the radio band by dialing *#*#4636#*#*, but process com.android.phone stopped working when I pressed "select radio band", even after I cleared cache in phone and sim apps.
Can anyone tell me how to fix the problem and get connected to 4G.
BTW, Network by Philipp Mangelow is not available anymore. Switching between 3G/2G and 4G/3G/2G settings doesn't fix the issue. I tried the giffgaff settings, but the APN gets deleted as soon as I try to save it.
Thanks

You may try to force 3G and then try to force 4G
You may try to user another IMEI number from a UMI device with 2600 support (of course backup/write down the original one before just in case)
http://www.ucc.co.ug/data/imei/2
After the update to Nougat 7.x how long does it take to do a full recharge?
Do you still have fast charge feature (< 1 hour) or do you lost it like all users reported so far?
What about your GPS? Do you have a fast fix after cleaning history and is it reliable (not losing signal often?).

Is it safe to change the IMEI number? and where can I find another number for a UMI device?
GPS is working fine, it fixes pretty fast, but I'm not sure about interruption in the signal because I haven't used it enough yet
