[Q] Why am I not getting signal at all...anywhere?

I just got a G2. perm rooted it. and everytime upon booting up it has signal for 1 second then literally just disappears and never comes back. can't choose mobile network or anything because it can't search for it. tried doing *#*#infor#*#* and it says GSM ONLY and everytime i try to change it to WCDMA PREFERRED it keeps reverting back as soon as i exit. the only way i've been able to get signal back so far is to connect to wifi and enable wifi calling, then after disconnecting i'm able to get signal and i'm able to check the WCDMA PREFERRED option but awhile ago i was on wifi calling then left my house and it was disconnected but wasn't able to get signal again.
can anyone help me with what i should do because although i might be able to get it back through wifi calling, this will be very problematic whenever i'm not near my normal wifi locations...
thanks for the help

Eh... I would try reinstalling a stock rooted rom.

Is it factory unlocked? Have you used an unlock code? Have you tried the full radio s off, super Cid thing?

I wonder if your SIM card is faulty, needs cleaning, or is just a bit loose in the socket.

This is what it sounds most like to me. Also try to install another rom since you have it rooted now and see if that fixes the issue. Make sure you do a Nandroid backup first though!

I never put an unlock code and I'm still on tmobile. I called them and so far I haven't had trouble with signal as much but my number doesn't show up under status in about phone settings...it just says unknown. Its only on this phone though, my n1 shows my number with this sim.

Just so we're clear.. Did this phone/sim combo work OK before your rooted the phone?

No it wasn't. For the past couple of days since calling tmobile, its been significantly better but today I did randomly have that same problem of no connection, but mostly right now my problem is my g2 not being able to read my phone number in "status" under "about phone" settings but it does on my n1. When I called tmobile they tried sending my number ota 3 times with no luck...

During the first 30 days you can go to a TMO store and get a new phone, pretty much "no questions asked". I'd go ahead and do that if I was you. Oh, go to a corporate store though, not a mall kiosk.
While you're there, get a new SIM, too. All free of charge.
If you still have the same problem after that, I'd try an exorcist

Is this problem solved now ? I got the same problem but have no chance to return it back.
If there is the way to solve it, could you please inform and share
Thx

My signal problems seemed to be resolved, at least for the past week. It was resolved by calling tmobile customer support and they did some tests. However, my phone not recognizing my phone number under settings> about phone> status, is still a problem. Even tried getting a new sim and still didn't solve the problem. Did numerous OTAs with tmobile that didn't work. My number still shows up on caller id and stuff its just that menu thing. Sounds insignificant but some apps use that to determine your phone number. Also, when putting my sim back into my nexus one, it does show my number...

Nevermind, my other problem was just resolved after reading a post in the cm6.1.1 thread. Settings-call settings-additional settings-my phone number.

suddenly no signal

Hi all,
A few days ago a friend of mine found a Wildfire S with an already stopped sim.
He then put in his sim and it was working perfectly, all connections available.
Suddenly after about 5 days of usage, it lost signal to the network provider but wifi and bluetooth still work.
Any help pls?

Has your friend tried doing a factory data reset?

Phone has probably been reported lost or stolen and normally the network that the phone was reported to would block it straight away, then they send the blocked imei number to the rest of the networks in that region and eventually it will be totally blocked on all networks.
At least in the uk its what would happen and it could work for a week or two until the networks update their database and add the imei.
This sounds like your issue, but I could be wrong.

[Q] phone unable to connect to mobile network

hello everyone,
I have my GSM galaxy nexus running aokp_maguro_milestone4 , 3.0.8franco kernel and xxkl1 radio baseband. I used to have no problems with my phone at all until I went on vacation to Spain (I live in Germany) in Spain I had signal but ever since I came back my phone has almost (in the time span of 48 hour it had maybe 1 hour of signal) constantly no signal from my mobile provider (BASE). I have tried reflashing the radio ( I had xxkl2 so I reflashed that and then flashed xxkl1), I have also tried turning phone off and on and leaving it 1 night without battery. any help??
thanks

Check your APN settings, if they are correct try to make a new APN profile from scratch.

checked apn and they were OK. made a new apn with values I found online and still no luck? should I maybe just restore everything to default and flash the stock from?

APN settings are only for data. They do not impact signal.
Go to Settings->More->Mobile network settings->Network operators and either select "Select automatically", or pick one from the list.

Just a suggestion but maybe a whole different updated ROM flash might do the trick

Like using a sledgehammer to kill an ant! :laugh: That should work as well.

Lmao I know but sometimes its just what's up. He didn't mention the ROM he's using. If he's that worried about this then its definitely worth a try. Like I said, just a suggestion. No need to slay ants over it

Swiftkey'ed on my CM9 Galaxy Nexus

Hi guys,
So I am still having this problem, but an interesting thing happened. I decided to stick the sim card of my gf (she uses another carrier which supposedly uses the same infrastructure as my carrier) and I had full coverage. After that I changed the sim again and had coverage on my line, but after a couple of hours of bad coverage it just never found signal again.
So what on earth could possibly be wrong and what can I do to solve this problem?
I would consider a new ROM, but this doesnt seem to be the problem.

Maybe you should contact your carrier and get a new SIM or check if there is any known problems in your area.

3G/Data connection hung up

I always have to reboot or turn to airplane mode to get it responsive again.
Its annoying cuz first, yay I can browse happily and fast, but after a few page, the data icon will stuck(arrow up and down wont change, stayed on white colors), which made every connection error.
Rooted/Unlocked/Custom rom/Custom kernel. Tried every baseband available but same trouble.
Is it related to faulty sim card? or is it my network is the problem? tried other carrier and worked fine though.
and fyi, AOSP gave less problems except connection drops sometimes(which is related to AOSP thing I guess) but data hang is not frequent. On Sense, every single time!

+1
Happens to me as well from time to time.
Anyone knows what is the cause?

I called my telco and ask them to check the connection with my number. they said its unstable and improperly connected. so they rebooted the (I dont know what they called) and etc. Rebooted my phone, turn on data, and damn it worked! Speedtest gave me average of 7-8 mbps for download. i rarely get that. now no more hung up. now i'm in love with my hox back. never thought thats the problem since other phones are working well previously.

[Q] Desire EYE network signal issue

Hi
My phone was working awesome, no bugs, no lags, good camera ... , but it started to act pretty weird about a month ago.
the problem is that network signal got weak. and by weak, i mean 90%of the time i have no signal!!!
it wasn't unlocked, rooted, s-off... nothing! fully stock!
factory reset didn't help, upgrade to lollypop made no change! i tried sim cards from different network operators, and non had signals!
i mean i had full signal bars at my work, but now, i have to search around for a place with 1 bar to put my phone on, and not move it!
do you think it's hardware related, or software?
i thought maybe, radio partition has a problem or something, so i searched for it, or an RUU to extract it from. but i had no luck.
u guys are my only hope. any help or idea is very appreciated.

hmmmmm, no one else having this issue?
no one has any idea?
no help?
this isn't how xda used to be.
it isn't how xda worked.
people would say anything on their mind, even 1% related, so maybe the problem can be fixed.
missing hd2 days. RIP xda!

Aw man don't be like that.
Did you drop your phone or something? Because it looks like a hardware issue to me.
I'd take it to service if I were you, cause I'm sure it's still under warranty. But if it's not, let's try to find a solution.

thanks bro.
no I didn't drop the phone.
the weird part is that my phone didn't lost GSM network connectivity completely, it's weak!!!! very weak!!!!!
I bought my phone from china and shipped it here, so I don't have warranty here. also it's a waterproof phone, and i'm not sure if it will be waterproof after being torn apart!!!!
I can not find any ruu for this device. :crying::crying:
I think the problem can be the radio driver.

You could try to S-Off so you could use any RUU. What CID are you? Maybe we could figure something out.

i cant s-off, because i'm in iran
my cid is HTC__621 (TW)
I really appreciate your help pal.

here are some screenshots about my issue!!!
as you can see in the first picture, i am connected to my network operator (irancell)
and when i search manually for network operators, this is what i see: (notice the star in front of my network operator)
now i move about a meter and no more signal, so i search for network manually again, this is the result:
as you can see, star is gone!!
and when i select my network:
what is going on? any idea?

May be a dumb question, but have you checked with different phones? Different Irancell SIM cards? Your SIM in another device? I mean, are you 100% sure it's your phone and not a problem with Irancell coverage? There could be a problem with one of their antennas causing you to have bad reception.

every suggestion and ideas are helpful for me.
about your idea, it was almost the first thing that came into my mind. so i checked different sim cards, from different network operators, the result was the same. i also used my sim in other phones, but it had no problem.
so i'm sure it's not irancell related. another important thing, is that my phone didn't have this problem from the beginning. after about 2.5 month, out of nowhere, it started loosing network connection!!!!!!
as you can see in the screenshots, my phone finds irancell with no problem, but wont connect!!! i thought maybe its radio driver/rom/partition.
so i searched for radio, to install it again, but i couldn't find it anywhere! :crying::crying:

hey pal
thanks for your opinion.
i cant do what u said because of 2 problems:
1. cant s-off the phone
2. couldn't find ANY ruu file for desire eye. none. not available.
Found one for AT&T!!
also i think EU is available too.
the only remaining problem is s-off.
(my friend has a nexus 5, and his phone wont connect to 3g, and he says its because of a physical damage. can my problem be physical too?)

My new htc desire eye won't toggle between 3G and 4g when avail
My network has forced my new htc desire eye to only select 3G as it was getting little or no coverage even in the city with 4g and was not auto changing down to 3G. Not sure if the phone has an inherent problem. According to my carrier it should be changing from 3G to 4G or vice versa auto depending on signal. So besides the fact it's not auto changing networks, it also seems I've bought a 4G phone that can't access 4G.
Any ideas? Should I turn it? Besides that it seems to work okay. I'm not an avid phone internet user though. TIA. . . . . S

Are you srue you can actually use 4G? Some providers charge extra for it.
Otherwise, make sure your network mode is actually set to "2G/3G/4G AUto". You can select it if you go to setttings -> Mobile Data (or wahtever it's called in English) -> Network Mode
Also, where you are, does a different phone with the same carrier (ask a friend?) have 4G?
