[Q] Cellular phone connection dead from one minute to the next - HTC One S

So...
I am running my phone rooted, but mostly stock (just some removals) with ROM 1.53.401.2 and he 0.15.3150S.19_10.31501S.06L baseband.
Its been perfoming fine ever since so I never bothered to upgrade to a custom ROM or the newer basebands.
Its an EU unbranded phone. As of tonight, with nothing special done to it it seems to have lost all cell reception. All I get is An x where the 5 bars are. Funnily, when I turn of my WiFi router and select wireless internet, I can get online and download data through the cellular inetnet connection. But not a single call or SMS will go out.
I have moved to like every location in my apartmant and outside and nowhere I can even get a single bar of reception or even a call through.
Does anyone have any idea WTH this could be, what could have caused it? Any ideas on where to prod and poke for a solution?

Mine did that for the first day after I put a non-stock ROM on it...hasn't done it since. I took the piece that covers the SIM card off and popped it back on. I don't know what causes it though.

T-Mobile network disconnection

Hi all,
First time poster, long time lurker I'd just like to say thanks to everyone in the community. You guys rock.
That said, I am having a minor issue with my G1. I have T-Mobile & my phone is SIM unlocked (I don't know if that would make a difference) and currently running JFv1.5 with the latest radio (2.22.19.26I). The problem is that when I disconnect from a wireless network, my data connection to T-Mobile doesn't pick back up. When I go into Call Settings / Network Operators I let it search for networks and sometimes my phone will have to Re-Register on T-Mobile and other times it will say that its already registered to T-Mobile but the data connection still won't work. The only thing I've found to solve that is a reboot of the phone.
This has happened a few random times when I was on RC33 and one of the Haykuro builds but it has become more frequent since I've updated to JFv1.5. Also, I dunno if it helps to mention but I went to a T-Mobile store earlier this week & swapped out the SIM card with a new one and have gotten the same results.
Is anyone else having this problem? I've searched to no avail and was curious. Thanks.
dissconnect
That's just typical crappy T Mobile service have the same prob here since I'm not close to a T Mobile tower when it loses web access it dumps the connection to reconnect
So that's it? I should chock this up to my carrier's signal being ****ty in random places? No one else has had this issue at all?

I am having this issue. Never had a problem until I updated the radio to the latest version
I have had the new radio since the JF build with cupcake. My signal was great until yesterday. It will go from the lowest to highest in the case of the bar. When I reboot my phone it takes much longer to connect to the network. BUT I think my issue is with the fact my market (Columbus, Ohio) was rumored to get 3G by this june. So I am guessing its just TMobile doing the upgrades and whatever they need to do to impliment the 3G rollout.
lately ive been having horrible service. dont know if it has to do with the new LX being released.
Hi,
I am on 5.02h and was having random disconnects on .26 radio.
I went back to .22 saffaire radio and my connection is more stable now.
I am not sure if others have experienced this as well.
I have flashed my phone yesterday with latest from Haykuro with CUPCAKE. (NO SD APPS)
Phone is running a little slower and I started having the issues with the DATA connection.
In the middle of the Web page loading, the phone looses data connection and I am only left with ability to use voice. The data connection comes back in a few minutes and same thing happens as soon as start using the data connection again.
I do not know if previously stable connection at my location all of a sudden became bad or the new build is causing this.......
just to add
Not to dissenlighten people here but t mob has crappy serivce to rural areas. I myself live in brunswick md usa. I have had. 2 bars since I first got this phone with rc30 with constant dumps to no signal all the time when it upgraded to rc33 still the same thing. Then I rooted my to jf rc33 still the same thing. After that I used jf 1.5 and it still craps out. When I go 20 mins to the north to frederick,md I get full bars and no dissconnects so if it where a radio issue there would have been some kinda difference between radio updates. I myself am a ham operator so I should know how radio signal works so when I chock it up to t mobs crappy service I do not do this lightly since the nearest tower is 20 mins either way from me. People need to stop blaming other peoples builds for this issue since the radio update is from google. If I pop a att sim I get full bar and no dissconnects cause the tower they use is closer that's how I know it's a t mob problem not an issue with the radio. Remember troubleshooting is the best way to see where the problem is. Till t mob puts up more towers and fixxes the packet loss to the phone to remedey this then we will all have crappy service which does not seem to be in the near future for anyone.
I had a similar problem when I was on stock RC30. I called in to tech support and they set up a new APN on the phone so it would switch back to EDGE faster if I lose the wifi connection. I would suggest if you're not around stable wifi, just turn it off.

[Q] mobile data not working, poor or no phone signal

Hey guys, I haven't done anything to my phone but all of the sudden, the data and phone signal basically quit working. I have a very hard time getting texts, phone calls etc to go though but it will eventually (usually takes a while or a few tries) and as far as data goes, I basically have no connectivity at all unless I'm on wifi. It says 3g or H every once in a while, but it's really slow and usually doesn't stay for long. I'm running CM9, and like I said before I didn't change anything that I'm aware of that would have caused this problem. It worked fine before, and it just stopped. Ideas? Thanks

have you called your provider? maybe its on their end.
I'm having the same exact problem... it shows my 3g it shows all my bars but instead of the bars being colored or the 3g be in color is gray. Also I cannot get back conectivity until I restart the phone. Does anybody have an idea what this is?
Are you on AT&T? I was not having any problems until a certain point in time, and I didn't change or do anything to incite them. I'm not even getting calls anymore, I'll just get all my texts in a wave every few hours. My data is useless, it won't stream, or load web pages, and my phone is frequently saying "Emergency calls only" when I'm sitting at my freaking house (which normally has full 3g and cell signal and is very fast)
This just started occuring with my 9020a on AT&T the first week of March. I switched SIM cards twice, spent about an hour on the phone with ATT, and sent the device back to Samsung who rolled back the software to 2.3.4 and the Radio to UKE1.
I still have the issue. Samsung says its not them. ATT does nothing. It;s liek the phone just stopped working, started dropped calls, missing calls, and the internet connection sucks. I have an iphone for work through ATT as well and have no issues with signal.
ANy help is appreciated.
Hmm
Make sure you have the right, most up to date settings for APN, and flash original radios. if it still doesn't work, make sure you have the i9020A, which has the at&t 3g antenna, not i9020T which has the T-Mobile antenna, vice versa.
Have you tried other radios for your device (make sure you flash the appropriate ones for your model)? Any signal info under Phone Information when dialing *#*#4636#*#*?

Sounds like you're having the exact same problem I am having. I switched sim cards, flashed different roms, etc and nothing. (although to be fair, after the new sim, things work better, but still not well) I'm about ready to pop my sim back in my craptivate and just go with that... or buy an iphone off of craigslist.

I am 100% sure I have the 9020a, but I don't know anything about APN and flashing radios. I have only ever flashed full roms before, so I wouldn't know where to look for the original radio.

I have not tried other radios. The signal info seems solid, sitting at my house, but the 3g is still horridly slow. It taked 15-30 seconds to load a webpage, even a pretty mundane one like google. Messages still come through in waves, and often won't send
About your APN, AT&T should provide you with the proper values to put in under Settings | Wireless & Network | More | Mobile Networks | Access Points Names.
If you are on ICS, they values should populate by themselves.
Can you try flashing other radios and see if you encounter the same problem:
http://forum.xda-developers.com/showthread.php?t=1116884
Make sure you backup your EFS folder (and all data for that matter).
I had similar problems, they were related to turning 3g on/off with a APN widget while the phone had little signal. As soon as started enabling and disabling 3g on the android options everything was back normal.

the data works most of the time now it's just retardedly slow. I can't stream music even on low quality, nor can I watch youtube without leaving it for 5 minutes to buffer,pages take forever to load, and I was downloading a 6 meg app and it took 20 minutes to download whenI was leaving the phone alone and not moving. I got really sick of trying to fix it and finally gave it to geeksquad to send in to get replaced. sigh.

[Q] Radio disconnects!

Here is whats happening! I go into an awful area with no cell service and when i return into an area with good service... It shows all my bars, 3G icon, but its all grayed out and will not return with color... Also i have no data connectivity at all. The only way to resolve this problem is a reboot. I have the Nexus s 4G KL1 radio... This has happened twice in 2 days. Can anybody tell me what this could be? I tried the KL2 radio and the same thing happened. So I went back to KL1. I am running Cyanogenmod 7.1 stable. Any help would be appreciated, I like this phone and dont want to have to go back to my slow Evo.
Happens on ICS ROMs. I switched back to GB because of that issue.
OHHH ok that makes sense since i was on an ics rom... That sux i love the ics roms to. Is this an issue they know about and are working on?
Yes I am sure the devs know about this issue. A lot of people already reported this issue on the ROM's threads. I think there was a fix in the CM9 repositories that was merged this week.
well thats good news since were i live its not good service and im in and out of service a lot. Thanks for chiming in and letting me know! I was wondering if i had a bad radio or some thing lol...
This happens to my I9020T as well (with stock ICS, Pixel ROM, and Brainmaster's Stock and MIUI ICS ROMs). So, it's definitely an ICS issue. My network connection won't reconnect after I ride the subway (underground, where there's no signal) for about an hour. The only way to fix it is by doing a reboot (enabling and disabling Airplane mode doesn't fix it).
I just tried switching radios: from KI1 to KF1. I'll update on the result later tonight.
Sounds like exactly what happened to me.
I went back to gingerbread. I haven't had the issue since!
Just out of curiosity have you tried the KL2 radio with CM9/Latest nightly and then toggle your Data Enabled or the data roaming? If that works it might save you the reboot. Settings, wireless & Networks/more, Mobile networks, Data enabled.
You could try toggling the data roaming too.
Yup tried it already

Ok it was worth a shot. When I travel to the UP, I get no data service what so ever. So I feel your pain.

I've tried enabling-disabling Data as well, and it doesn't fix it.
The weird thing is the same issue happened to my girlfriend's T-Mobile G2 with Gingerbread last week, when I unchecked the "Use only 2G network" setting on her phone and forgot to check it back. So, when she told me the issue when she got home, I re-enabled the "Use only 2G network" setting again, and her phone haven't had the reconnect issue ever since.
So, my speculation right now is this reconnect to network failure issue has something to do with the Nexus S' 3G/4G network type setting.
I definitely think you're right
I am having somewhat the same problem.
My phone keeps switching from UMTS:3 to HSDPA and back to UMTS:3
This is draining the hell out of my battery. But when I have it on EDGE 2G I'm getting good battery life.
the issue is not that big for me. I just give it a few moments with it in sleep and when I go to use it again it fixes its self.

Update!!!! I have since switch off of the I c s rom. I have not had the incident happen even 1 time since doing so. I am totally convinced it's on ice cream sandwich roms.

I doubt the radio would make a difference. I think the issue lies in the Phone application.
I could be misinformed here, but if i recall correctly, our phones radio is relatively stupid as far as radios go, and the intelligent parts are actually done as a part of the phone application. This only applies to CDMA Variants of the Nexus S, but it could be the reason that the ICS update was pulled (As thats where CM and others get the ICS version of the phone app.).
After taking the subway for about an hour last night, my NS actually reconnected when I got back up to ground level. One thing that I didn't do is listen to music (PowerAmp); I was always listening to music when I had those network reconnect issues.
Anyway, I hope this issue gets fixed in the upcoming official Google ICS update, that should be released in a few weeks*.
*http://www.engadget.com/2012/03/15/confirmed-ics-coming-to-the-nexus-s-in-the-next-few-weeks/
I've found that if you just stick it in airplane mode when you are about to go into known no service area and then take it out of ap mode when you know you have a signal you can save from having to reboot to reconnect.
My building at work is a tomb for sprints signal and it works for me every day w/o rebooting ...
To all of you having network reconnect issues -- do you use any battery saving apps, like JuideDefender or GreenPower? I use one, and I'm thinking that its network toggling internal API method has something to do with this issue.
Yesterday, I disabled my GreenPower app right before I took the subway, in which my NS couldn't receive any network signal for about an hour. Then, when I went back up to ground level my NS was able to reconnect to my network successfully.
I'll do the same test later after work and update back tonight.

[Q] 4g data drops often...too often

i have to reboot in order for the 4g data to work again but it only stays on for about a minute and then it stops working again. everything else on the phone works ( text, voice, wifi etc...) I read somewhere that flashing different radios might fix it but im not sure about that. anyone else experience this and have a work around? i am currently on baseband i535VRLG1
Thanks In advance
i called Verizon and they said it may be the sim card thats damaged. if that were the case wouldnt voice and text fail as well?

I'm having the same issues recently. I've always gotten a 4G signal at my house (albeit not the strongest one) but lately, my phone will not hold on to the connection. When coming off of wifi, my phone will not acquire a data connection at all most of the time. I can still send/receive texts and calls but there is no 4G or 3G icon, no MMS, and no data. I have to toggle the radios on/off, or change from CDMA/LTE to Global (or GSM) and back, put in airplane mode, or restart.....there is no guarantee any one of those steps will work. Sometimes I have to do it repeatedly until I get my data connection back but it is only temporary.
I'm on the i535VRBMF1 baseband and updated to the ML1 modem to try and resolve but to no avail. I have replaced my sim card (as I initially though that was the issue) but it has not helped either.
The only thing I can think of is that my PRL may have been updated (it is currently 15310) and it's causing issues with the towers in my area.
I just got back from Hawaii and was also in San Diego for a few days and had absolutely no issues. It seems to only be an issue now when I'm at my house which makes me think it is something VZW network related and nothing to do with my phone per say. It's really driving me nuts though.
BTW, I'm in Southern California (Irvine).
I seemed to have fixed the issue by reverting the baseband back to vrlf2. I had to switch from global to 4g/LTE because I vegan to inch roaming charges lol. Verizon credited me and no dropped 4g signal. So I'm happy.

What ROM are you running? I'm just curious what the implications are of running an older baseband (from the ICS days) on a newer ROM/Kernel.
I'm running cleanrom8.1 core edition. Slightly buggy but tolerable.
I was finally able to somewhat resolve my issue so I thought I'd post in case anyone else is experiencing something similar.
By using a few different apps and testing techniques, I was finally able to deduce that my issue had to do with EHRDP hand-off with the towers in the immediate vinicity to my house. I'm not sure what VZW did to them lately but it doesn't appear to be a problem in other locations so it seems like the issue is on their end (and not something to do with my phone).
In any case, it seems that when my 4G connection is weak and EHRDP is detected, it is dropping the connection entirely instead of handing if off to 3G (EVDO). The connection is also never transferred back when a 4G signal is detected either until I reset the connection where there is a moderate 4G signal.
Again, this only seems to be an issue when connected to the towers near my house and doesn't occur when traveling abroad.
To fix this, I have disabled EHRDP by doing the following:
1) Open the dialer and type *#97328640#
2) Select "[2] CDMA"
3) Select "[2] Data"
4) Select "[7] eHRPD e/disable"
5) Select "[2] Disable(*)"
6) Reboot the phone
Now my phone switches between EVDO revA. for 3G (using the native protocols) and LTE rather than relying on the broken eHRDP protocols. This workaround will have to suffice until VZW fixes stuff in my area but at least I don't miss MMS messages anymore.
Hope this helps anyone running into similar situations.

[Q] No signal strength all of a sudden

Hello,
I bought my Nexus 5 on the 11th of December 2013 and it had been working flawlessly ever since. Since last week, I started noticing the occasional signal drop and I'd be out of cell reception but would usually be back up within no time. However, yesterday, out of the blue I'm travelling on the highway and my signal strength disappears never to come back again. I've tried the following:
- Restore old backup (including EFS)
- Went back to stock from PA
- Upgraded to the latest radio
- Took back cover off to see if anything was wrong but found nothing.
- Tried another SIM card
Nothing worked. My SIM card works fine in another phone. Everything else such as WiFi and Bluetooth works flawlessly but I just don't get any reception.
This is very disappointing and I have my fingers crossed hoping someone can help me with this since I didn't plan on getting a new device for at least another year especially after paying $520 USD for my phone here in my country.
Thank you for looking.
im having a similar problem with the radio after the last few otas. im getting a lot of dropped calls on 3g aws...
im going to try to revert to an old radio as i don't think this is a hardware failing issue..
Sent from my Nexus 7 using Tapatalk
Flash stock firmware with fast boot. If its the same, its a carrier issue....call them to see. Or its hardware failure.
just wanted to post my fix for this issue - very disappointed with Google that i had to do this...my provider is mobilicity canada (3g aws band fyi)
flash krt01b radio from this thread...
http://forum.xda-developers.com/showthread.php?t=2514095
this is *not* a carrier or hardware issue (at least in my case)
seems others are having same issue
https://code.google.com/p/android/i...s Owner Summary Stars&groupby=&sort=&id=70878
Then it is a carrier issue....cause on Telus in Canada....never had an issue with any radio version. ?
telus would have a stronger overall signal but uses AWS band for lte which is different than mobilicitiy 3g aws...
I'm not disagreeing.... Just saying its the carrier....not Google.
See my point?

are you saying mobilicitiy is purposely weakening their cell signal cause they are almost bankrupt ?
i still blame google i had no issues with the radio before they borked it...

Just saying that unless many have the issue with the phone or radio, then its an issue.....if not, it isnt .
So in this case, it leaves hardware or carrier....assuming a stock flash didn't help.
If flashing another radio helps the OP...awesome!! But the new radio does work fine for the mass majority.
Hope it does work for him tho!
