[Q] No data and no calls

Randomly I have not been able to text, make calls or get a data connection with my phone. I was running CM 7.0.3 when this all of a sudden started. Restarting my phone would allow me to make calls and get a data connection for a few minutes and then I would not be able to do either. I flashed the newest CM7 nightly build and a new radio, Vision_Radio_12.57.60.25_26.10.04.12. The same problem continued so I flashed Virtuous 2.0.0 but that made no difference.
Anyone have any idea of what I can do to fix this?
Thanks.

I'd say try flashing a different ROM. But since you've fresh flashed the same ROM I'd say that pretty much counts.
Next I'd call the carrier and confirm that you SIM/account is in good standing, and that the towers are working properly in your area. I've had the freakout about "omg my phone is jacked up" and after flashing all kinds of ROMs, radios, etc. I just called T-mobile and they confirm that there was just a network problem in my area.

ur doing a full wipe right?

I actually did flash a different ROM and the issue continued. I'll be contacting Bell to see if maybe it's a service issue.

If you contact bell they'll know that you rooted your phone and they will have less sympathy to help you fix it.

How? Do like I did and google the right build number for your device because they will ask, and you don't want to get caught saying 'GRJ***'

This.

i tell my carrier straight up that im rooted...they dont say anything...but im not calling tech support either

If the OP is just calling to see if their have been any reported service outages or interruptions in his area, whether he is rooted or not shouldn't matter.
A couple times in the past few years, I've had instances where I lost both data and voice service for up to a couple hours at a time, over the course of several days. Then the problem just goes away. This seems to fairly typical, if they are upgrading or repairing your local tower.
If the OP has tried flashing various ROMs, and tried a new radio, I'd be inclined to say the ROM is not the problem. If the problem persists, you may ask your carrier to send a new SIM (or go to their store and ask for one).

hi,
you are not alone!
i have this problem with OE HTC 2.3.3 stock rom! (unrooted original device from Nov. 2010)
so i had very bad mobile connection and after ~1day (without reboot) i can't phone with it.. mobile network only "x" but data connection is fixed to gprs.
very strange!
so i send my phone back and orderd new one.
i think this is was hardware problem.
short:
- reboot bringt full funktion but the mobile connection is not so good as 4month ago (same point).. 4month ago it was "H" and now only gprs
after many hours >8h. calls didn't work, the phone said "no provider"... (x)..
- the strange thing is that data connection is degrade to gprs
this problem exist from the last 2 HTC OTA updates. but onyl the last 2.3.3 makes it really unusable
i hope this problem don't come back with the new desire z now rootet with cm 7.10 rc1 (what a feeling)

[Q] Baseband switching nightmare

Hi folks... I'm give up for searching. Let me open this thread.
I've been using CM7 and I never got this problem. My phone aways worked without touch baseband switcher option. In last Saturday my Defy started to lose carrier connection. Sometimes it show "only emergency calls", sometimes it show my carrier signal but I can't receive or make any calls. I need to reboot my device, then it works for a while. And yes, because of that my battery is draining very fast.
I've tried everything but nothing is working. I tried to change baseband, wipe cache/data/factory reset, delete bp_nvm_default folder contents and run baseband switch again with every available band option, re-flash everything again from stock Froyo, set up 3G only, 2G only, 3G preferred, flash older CM7 versions, flash last 4 Miui releases too... but it still losing connection. Believe me, I've tried every thing that I can find on google.
My carrier is "Oi", and my phone suppose to be working in 850/2100MHz mode. Could you guys help me? Is there others things that I should do? This could be a hardware problem? I don't think so, with stock Froyo rom it works flawlessly but I don't want go back to it. I don't have another SIM card to try.
I'll try a last shot: flash Froyo again and save bp_nvm_default for CM7. Maybe this could work, I don't know, I'm completely lost. But for now I need sleep, I'll try tomorrow.
Thank you! And sorry for my grammar mistakes. I need more English lessons.
UPDATE: With my friend's chip (TIM carrier) I've got no signal troubles, it's working like a charm. Now I put my Oi chip again and guess what? Yes, my phone loses signal after 15 min. God dammit, it's something with my carrier. I need to call them for support, but my carrier's call center people are a bunch of stupid morons. I can't figure how they could understand that I'm using an alternate firmware, i bet they will say that I need use only official firmware.
UPDATE 2: Ok, there's no way to make this work at Oi's network, I don't know why. So I moved to TIM. Using stock firmware isn't a option, since Motorola can't make a decent work, Motoblur sucks a lot. CM7 or MIUI running Gingerbread are much better than stock Froyo, even without Motoblur crap. Thanks guys for the answers!

Thanks! But yes, I tried it too.
Right now my system is running a Miui 1.10.28, using a RT brazilian Froyo as base (SBF file name: JORLA_U3_3.4.2_107-9_SIGNED_USAJORDMR1B15RETBRL). By the way, I've been using a Nordic 3.4.2_177-005 base system with Quarx's CM7 nightly builds for 4 months without problems, until last Saturday. I could test 3.4.2-179-2 CEE DEBLUR later, but I'm afraid that can't resolve.
Serious, I'm tired of this. Unfortunately I'll go back to brazilian RT froyo, with Motoblur s*** and slow down my system. I'm losing important calls this way. :'(
EDIT: My friend here in my work gives me his TIM chip, so now I'm testing it.

If this makes you feel any better, you are not the only one with this problem..i used to get no network using my sim but my mom's cardused to work fine (i use cm7)..no matter what I do, this problem keeps coming back after a month or so..and I have never flashed a stock ROM usong rsd lite as I have read many people screwing up their defys in that process..so did the only thing I could- changed my sim!

I've seen, I read many issues like mine. Let me ask you: are the SIM cards from the same carrier?
My phone used to work too. It was running CM7 for 4 months and now started to lose signal suddenly! So that's why I flashed it with RSD Lite 8 times and tried many CM7 versions and Miui last weekend. Maybe I have luck, but I always did it with 100% charged battery.
I'll call TIM, maybe they could give me some advantages or a equivalent plan. So I'll change my carrier.

i changed my carrier...i am not sure whether the same carrier SIM will work...i couldnt find anybody with the same carrier's SIM...so played it safe and got a sim from my mom's carrier..

going back to stock should really solve your problem...i wonder if it is a hardware issue covered under warranty...why dont you try getting it replaced??

Well, my phone is 7 months old. Warranty is still valid, but it works with stock firmware. So, I can't ask Motorola's support for replacement or fix it.
There's something wrong with my carrier's network. Here in my state, it was known as Brasil Telecom, but the company was brought by Oi, and they are joining their networks. When I had my old phone, it recognized BrT network, and a roaming signal appeared. The same happens when I use my Defy with stock firmware. But while I'm using a CM7 firmware, the phone show OI as a network available, no BrT and no roaming indicator. It's a bit weird, isn't? Oi's support can't explain why this happen, they just say that it's normal and that they won't charge me by roaming. I just can't realize how it was worked all this time.
Maybe I should change my carrier. Sometimes it delay my txt messages (send and receive). I took my sister's SIM card and I let it all day in my phone. TIM, again. And I have no signal losing, no battery drain, phone get on sleep mode normally. I need test it with SIM cards from Vivo and Claro, just in case.

Yeah, my case is just like a incorrect baseband. But there's something more, it's just impossible to be only a baseband issue!
I tried with the newer baseband switcher. First time I tried RT Brasil, them TIM, Vivo, Claro... so I started to try every single option. I don't know what I should do anymore. The solution seems to be change my carrier.

Hey bro! I had the same issue as you are experiencing a few days ago. Here's what I did:
In Baseband Switcher, choose the middle tab (i think it's europe or something), then select International RT (it's the first one).
Worked like a charm. (w/ TIM and VIVO)
Hopefully it'll work for you too! Good luck!

I said it already, I tried it. With every single option. The RT international was the 1st option after the brazilian's options.
I'm moving to Tim. Now my phone isn't loosing signal. Oi's network sucks.

[SOLVED] Low/No signal and low/no data connection.

Hey,
I noticed that around two days ago my HOX started acting up.
It has low to no signal most of the time, no data connection, or it shows the data connection with the "E" letter.
I have rooted it long time ago, and ran RENOVATED rom, and had no problems. it started without me doing any alterations.
So I switched to Revolution to make sure it is not rom related, and the issue persists.
Any ideas what could be the problem? tried searching for it, nothing seemed useful.
Phone details:
Kernel version: 3.1.10
Baseband version: 5.1204.162.29
Build number: 3.14.401.31 CL128187 release-keys
Thanks!
SOLVED: Read below for details.

i suggest changing networks to make sure its not a network related issue

Changing the network, by that you mean trying to change the SIM?
I have tested another SIM and I still had the same issues. and my SIM seemed to be working fine on another device.
GetLIR reported that I have the correct versions. I am really clueless as to what is the problem..

yeah that's what i meant - did you try a factory reset ?
And if that doesn't help either i think you should backup everything and get back to stock then start everything again from square 1 .
why fix it if it ain't broken ?

hi!
thank you for your post, did you by any chance take pictures of where that cable is?
and how dificult it is to reach it?
my phone is under warranty, actually just came from service, and now im having bad signal reception, in the same areas where my previous "i" phone had full bars allways and no problems with signal, no drop outs, nothing,
and with Hox is almost very low, or no signal, and constant breakups in withing calls.
sending it back to service is pain in the ass, its far, postage, time to wait for them to fix it, again....

I have the same problem, every now and then it will stop having service and the only way to get it back is by rebooting, sometimes it works at first sometimes it needs a couple of reboots.
Any hint with this would be great

same problem and i'm having invalid imei

im having almost identical problems... like a month or 2 ago i reflashed to the new 4.3 slim rom. I have been fighting this thing every since. Ive tried so many different radios but yet i still have this issue, sometimes i can go days without problems but now it seems to loose data even sooner. ONLY way i get data (4G) back is if i reboot. Ive tried disabling then re-enabling data, same for airplane mode, nothing works. I think part of the problem is this damn rom.... i used to be on black bean 8 and for the mobile networks it had an option for "CDMA/LTE". This rom must be a ported rom cause the only selection for mobile networks that work is "CDMA/EvDo/GSM/WCDMA". I am on Sprint CDMA and LTE. i dont understand why this was done like this. I Would like to go back to blackbean 8 but i had problems with it and i like some of the settings for this rom better. Anybody have any ideas? Ive tried ALL the radios, none seem to be stable.
oh and i would post in there for the rom's forum but seeing as i havent posted enough here im not able to ask questions about it or anything :-/

Not Connecting To 3g, Only Working On GSM

I've been having a strange problem with my S3 lately, all of the sudden, the connection to 3g network has only rarely been working. It shows that I have a signal, and that I am actually connected, but I can't make calls, send texts, or get data. It has been rooted with Liquidsmooth for over a year with no problems, and I didn't flash any other roms or anything else that I can think of to cause this. I tried flashing another rom, restoring to an older nandroid backup, nothing fixes it.
After searching around, and being unable to find any solutions, I flashed back to a rooted version of stock (root66 T999_UVUENC2). I've talked to Tmobile, and they suggested trying it is gsm only mode, and that actually works ... I can call / text while on gsm, but obviously I don't get 3g data. When in regular network mode, it does the same thing, shows signal and that I'm connected, but nothing works.
So, any clue as to what could be going on here? Is it just a hardware problem like an antennae going bad, or could there be some software issue causing the problem? Thanks, any information would be helpful.
My current setup:
root66 T999_UVUENC2
Kernel 3.0.31-1962493
Baseband t999uvuenc2

They probably would've said something when you called, but check if the imei got blacklisted somehow. (Mistakes have been made before).
Also make sure you're still using the correct APN.
Beyond that I'm just not sure what to tell you. Since you've gone full stock, it most likely means its either a hardware or network/account problem.
Have you made sure you're not being throttled?

Tmobile checked my account when I called and they said there's no problem on their end and that it should be working. I double checked the things you suggested, no luck. And since nobody else that I know with Tmobile is having problems in the area, so I guess it has to be some kind of hardware problem. Thanks for the help, guess it's time to start looking for a replacement.

Maybe you could troubleshoot by trying you sim in a friends phone and their sim in your phone to see if the issue persists with either the sim or the phone. If it is the SIM, you know it is on T-Mobiles end, if it is on the phone you know it is on your phone. I would also try re-flashing everything just to be sure it's not in the software/firmware before spending money on another device.

Didn't someone say it was a problem with the ROMs base not working with the radio/modem? If that's the case it probably won't be fixed until the base is fixed. Think they said it was CM?
