[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.

Network Connection Issue - No 3g/4g

OK, I have been dealing with this since I bought my GSII and cannot find any information about it.
Firstly I want to say that I am completely stock and unrooted.
My phone does not like to keep a stable data connection. About 50% of the time, when I try to do anything that requires a data connection (facebook, browser, gmail, etc.) the 2 arrows under the 2g/3g/4g icon will stick being grey and my phone just sits there "loading". I tried a factory reset, didn't install any apps, and also got a new sim card and the issue remains. It happens everywhere so it is not just a bad network connection.
I decided to post the question here because yesterday I was playing with my brother's GSII, and his did the same thing.. So it made me think that maybe it wasn't just me. Has anyone else experienced this? Or does anyone know what might be the cause?
Edit: I set my phone to use 2g only, and the problem vanished.. So it doesn't like to connect to 3g/4g.

Try going to your mobile network connection settings, choose access point names, hit your menu button and click "restore defaults".. It may fix it, I had data issues and it did the job. Hope it works for you!

Do what the gut above me said. Also call Tmobile and tell them, they will refresh your data connection on their end. That will clear up three problems your having.
But if it's also happening to your brothers phone, it's a network error. Call Tmobile.

I restored the apn settings and had Tmobile refresh my data connection, and it still happens. I noticed today that it's not just data, I'm also unable to call or text when it happens.. Tmobile just said everything tested normal so there is nothing they can do.. And I really don't think it's the phone so I don't want to exchange for a refurbished unless I have to.
Sent from my SGH-T989 using xda premiu

Its happened to me before. For about a week, the data connection just dropped. It would come back for a bit and later vanish. I called t-mobile and they guided me through routine steps (i.e. taking the battery out, rebooting, resetting) but nothing seemed to work. They really couldn't figure it out and later told me to replace the SIM. I can't remember if they shipped me one or had to go to the store but either way that relieved the problem. This was on an HTC HD2.
That might not be the case with you though. At one point in time all the phones under my name lost data connectivity just as you explain. This really had no solution but to wait it out.

you mentioned your brother's is doing the same thing, its probably not the phone, but rather the cell tower your connected to is fuggin up. Try going 5 miles from where you currently are and see if its still happening.

Network error
Sent from my SGH-T989 using XDA App

Just in case it's not a cell tower or network problem . . . My SGS2, purchased in October, had the same symptoms as the OP. After trying everything the OP did, and more, I came to the conclusion that the firmware on the phone was corrupt. I used Odin to flash the factory stock ROM & Kernel images (2.3.5 at the time). There was a definite improvement in the faltering/hesitant/fail connectivity problem at that point, but it was still very subpar. So I then also flashed, again using Odin, the baseband ("modem") image - I did it twice for good measure. The problem was finally immediately solved at that point and I had very prompt loading of webpages, etc. Still working fine months later (and even better with a custom ROM). See the thread entitled "[Q]Is there a "true" factory restore for T-Mobile Galaxy S II?" for help about the seemingly same symptoms/problem you (and your brother) are experiencing. If your underlying problem is in fact the same as mine (and the poster of the thread I cited) then it's apparently either a bad factory flash or a post-factory corruption occurrence that is causing your problem . . . the coincidence of your brother also having the same problem aside. Good luck!

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.

Crawling internet over data & NO Downloading

Problem:
The speeds which I get over 3g are ridiculous!! can hardly access any website, everything keeps timing out !!
I can't even download a 300 Kb File !!
Be it over Google play or any other download using the browser, I just can't download Anything.
The download starts..downloading on the notification bar..after waiting for a couple of minutes, it times out ??
Is anybody else facing this problem??
Has it got something to do with the E-988 model ??
Tries:
1.Tried switching carriers(3 different ones)>>same issue with everyone of them
2. Used the 3g/4g optimizer app along with the 3g tweak script by Zepplinrox>>NO effect
3. Tried to find a copy so that i can flash a new radio for my E-988>>couldn't find one
4. Tried using GetRIL but it said my phone is not supported.
There is Absolutely no problem with either downloading/internet access while I am using WIFI, but as soon as I switch to data, it just dies out
Any solutions/suggestions would help out a lot..
>>Took my phone down to LG service center, they said it works just fine:laugh::laugh:<<

Numerous factors depict whether or not you get a good speed when it comes to data. Location, congestion, company and location again.

Agreed man..but still, No 3G is that bad that you can't download a freaking 300 Kb file..
I assume that the radio is messed up..
waiting for someone to post native radios for Asia region..flash & try them out..

Make sure you are using the correct APN`s
It might be a good while before those modems are posted things seem slow around here. Make sure you are actually on 3G as it says 3G at the top and not 2G/E right?

I use E988 too....and have no 3G problem so far.....

APN is correct for every SIM. The problem doesn't seem to be with the provider, its either a hardware issue or maybe a software issue.
I have 3 GSM micro SIMs from 3 different providers..
The GSM signal keeps fluctuating..1 bar to 5 bars(no issue with audio quality though).
Never ever seen a 3G icon on the phone, hardly get a HSDPA(H).
>>Googled stuff and tried to Force my phone to WCDMA only, started having network issues..
>>checked ur stuff on build.prop edit as well..tried that..Didn't help..
>>Have a HTC One X as well, 3G works like a charm on that..

It would have to be hardware. If it was software everyone else would be having the issue

Thats the thing..I took it over to LG service center. They kept it over the weekend and said there was absolutely nothing wrong with the hardware !!
I told them it could be an issue with the receiver antenna (read it somewhere).
They said if that was the case then WIFI would be affected as well (which isn't).
I'm still confused.
Thanks for the input thiough..
will post if there is Any improvement.

same problem on f240s. wifi speed and stability is great, but mobile data is just way too slow.. i cant figure it out..
im usually stuck on "g", dont think i ever saw "3g" there.. the only thing that i think could be the problem is the 1900mhz frequency that my model doesnt have, but it has the 2100mhz frequency that my operator uses along with the 1900mhz frequency..
is there any way to resolve this? i saw some ways to convert the phone to e988. would thet help? i tried to alter things in the secret menu, but no luck. no setting worked except automatic..

[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.

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?
