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!
Use a firmware specific to your region as base.

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..

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.
i have the same issue... fixed with correct band !

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.

Hi there,
my girlfriend has some problems with the 3G connection of her HTC One V, hopefully one of you can help us
She´s using an o2 simcard in her One V. If the One V is powered on for some hours/mintues at a time it happens that the 3G connection isn´t working any longer?
You can still see the H(SDPA) / E(DGE) symbol in the topbar, but nothing is working?
If she turns off and on her mobile connection, nothing happens.... 3G is still not working.
The only way to get the 3G connection working again is to turn the flight mode on and off again. After that everything is working as usual.
(A reboot is also working)
As I got my HTC Desire 2 1/2 years ago I had the same problem,... after an android update everything was working as it should.
But these 3G problems are really quite annoying
Is there anybody out there who has (had) the same problems?
She´s using the HTC stock android 4.0.
Hopefully it´s not a hardware defect
Thanks for your answers so far.

Sent from my One V using xda app-developers app
that´s not so easy because she has a contract with o2 ...
I don´t believe that this is a hardware error, because after booking in into the cellphone network everything works as it should... but then after some time it suddenly happens that the 3G network is dead
i have to ask, but is the back cover on?
of course, back cover is on. I also don´t think that this has something to do with the back cover (or any other hardware) because like i just said after switching the flightmode on and off everything works as it should ... i´ve googled in the meantime and I found some other people who are also on android devices and they´re having the same problem.
here´s a german article of people who´re having the same problem
http://petitionen.com/p/internet-vverbindungsprobleme-bei-android-smartphones/sign
This also confirm my doubts... I had the same behavior on my old HTC Desire ... but after I´ve flashed another rom everything has worked perfectly
seems to be an android specific problem

Its not gsm, right?? You can't get a sim from somewhere , out it temporarily and try?
Sent from my One V using xda app-developers app
it´s a GSM smartphone...
well, actually i have no chance to try another simcard in the phone...
Moved to Q&A. Please ask all questions there.
Could it be possible that the problem is due to the baseband version her One V is using?
If I remember right i´ve upgraded the radio rom, too when i was flashing my Desire 2 years ago. After the whole flashing procedure the error was gone?
I had the same problem. REBOOT and it worked again
Edit: if you're saying that this happens occasionally you'll have to bare with it. Mine happened every 20 days or so

have you try using another carrier? or is your phone primo c?
If the phone is locked to a carrier he can't use another sim to get service I think he's trying to say, so sim from another carrier is out of the question.

well, i mean if he can temporarily change sim with his/her friend just to make sure what's wrong..
the phone isn´t locked to the carrier, but i don´t want to buy a new simcard just to make sure if the phone is working correctly. I´ve already thought about installing a custom rom.
Can anyone advise a good custom rom for One V which is working correctly with all functions? (Maybe a Jellybean Rom?)
Thanks so far!

Are you sure HSDPA means falling back? Imho it's only a type of 3G and it is really fine if you see H for mobile data mode. I might be wrong or this might be treated differently by country/operator.

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....
Hello guys,
I live in a big city and the network coverage is not a problem here, nonetheless from time to time people try to call me and they can't because somehow my phone loses network signal. This never happened with other previous roms,
I already missed really important calls because of this and it's really annoying,
What can I do to fix this problem?
I'm using the world generic stock rom.
Any help will be much appreciated.

Do a factory reset and see.. If that doesn't solve the issue, flash the ROM again.. Wipe everything, make a clean install.. On second thought, checked with other SIMs?? If yes and if same thing is happening, do as i said first.. If in worst case, it still happens then its H/W related problem.. U will have to check the SIM slot..
I was reading something about modems, do you believe it can be related? One should use the world generic rom or a specific country rom?
Also, can I get the B.200 rom and flash it, or I can't downgrade just like that?

Don't flash a buggy ROM.. I use the World generic as well.. No probs.. World generic supports all networks.. Atleast most..

That's the problem of your N/W carrier i guess.. See by changing SIM once.. If problem doesn't occur then its the problem of your carrier.. If still occurs and if u got warranty, take it to Sony Service Center.. It might be H/W problem..
Hi,
I own a Xiaomi 11 Lite 5G NE. I have updated to the latest MIUI Official V12.5.8.0.RKOEUXM.
From the beginning, I'm facing the issue that mobile data is not working. You're navigating and suddenly all stop and finally it shows the error no network.
After restarting is working fine again but it's very annoying. I've been looking for help but nothing found has helped.
Is anyone else facing this issue?
Thanks for your help and time!

Hey. There
For some Days I also having mobile data problems. My phone så browser says No internet connection..
When i turn phone off or disable mobile data off for 30 min IT Works for a short period, then IT stopps again. I can use Wi-Fi at home.
I have factory restored my Device but its didnt helped. Swiched to second sim slot and nothing..
Gould be cool od someone knew how to fix it. Or need to send it in. Had this phone 3 months .
Specs..
Xiaomi 11 Lite 5G NE
MIUI 12.5.7.0 stable
Model 2109119DG
Same problem here. I'll preface this by saying that I work in a place where the reception isn't great, but with my old Huwaei it never happened.
When I lock the smartphone and then unlock it after a while it shows 4G+ but in reality there is no connection.
Last night at the gym (in a basement where the reception is zero) after I left it wouldn't pick up the network again.
To solve it I have to put on and take off the airplane mode.... Very very frustrating.
I also replaced the sim card with a new one but no dice.
MIUI 13.0.5.0 Stable
Thanks all for the replies.
So I'm not alone, but it looks that some people have not issues.
Looks also problem is on MIUI 12.5 and also on MIUI 13.
I think it is a hardware problem, not software.
In these days Ill take it in assistance and I will update you.
Unfortunately, it has been too many days since my purchase and I can no longer return it. Super regretful that I didn't get a samsung a52s!
Need to that we had igły weather here with lightnings and storm . Many trees was Tilted.
But checked mobile operatora site and nothing there.

I also had major issues with my mobile network on 1 of the simcards. (I am using dual sim)
If your provider supports 5g then call with the dialer *#*#4636#*#*
you will see a menu with 3 options. the first selection is simcard 1 the second simcard 2.
change the prefered network type to NR / LTE / GSM /WCDMA or whaterver ur provider is supporting, NR = 5G network.
Make sure you disable VoLTE for both the sim cards since this was disabling my download from mobile networks.
hi guys, yesterday I took my cell phone out of repair. They replaced the motherboard and now it seems to be working fine, no signal loss.

Hi Raulci, i replied u in the other thread!
Just wanted to let you know that during the last weeks, I haven't experienced any other mobile data issue again. I have changed anything. Let's see if it continues this way.
Yes its a problem. Initially i thought its miui 13 problem. But reading above comments with slow speed/ 4g connectivity issues in 12.5 it seems its hardware related. Inferior modem or low quality antennas could be the case. I was hoping to fix by reverting to 12.5.
Same problem i have mi 11 x i even go to the service centre they factory restart my device and it's not fixed they said it must bu hardware problem
