[Defy Q&A, Help & Troubleshooting] cyrusct82:
I had some RIL bugs. So is not the SIM card. It's a hardware problem or a network problem or a combined problem. So to avoid this problem I use the phone on 2g only connection and I use the 3g connection only when needed.
[Defy Q&A, Help & Troubleshooting] robiwan kenobi:
Hi guys, it may be helpful for someone.

I've struggled with connection loss whilst on 3g since a few months. Tried different roms, base bands, hard wiped and flashed my froyo sbf and still facing random signal loss.

Until today.

Finally I've read a post that it could be the sim card incompatibility problem.

Three months ago I have upgraded my Voda contract but the new mobile has gone to my wife. Unfortunately I've got a new nano sim with it which I have decided to put into an adapter and than into my Defy. Thought it's better to have the newest sim. After that starts problems. Previously thought that is because of the adapter and replace it for another new standard sim card, but that has changed nothing.

Today have looked at my prime sim. The size of the card is obviously the same but the size of the chip is bigger. That makes a difference. I have activated my very old sim (back again) and have no signal loss since that.

The only problem now is self rebooting. I'm running froyo for now but going to wipe everything once more, put my froyo sbf then custom rom and we'll see.

Sorry guys I have just frozen bar and no signal
[Defy Q&A, Help & Troubleshooting] athenus:
What are those RIL bugs / where can I see if they are my problem too (is there some kind of logfile)?

P.S.: FYI here is a german survey about experiences with the RIL bug. Defier said he's gonna evaluate them soon. I will try to translate it then.
[Defy Q&A, Help & Troubleshooting] cyrusct82:
When you will have this bug you will see by your self how is affecting you.

-in stock Rom random reboots

-in CM7 build newer than 05.12.2012 you will receive a message that the RIL had crashed and asking you if you want to restart.

-in other builds the signal bar stays full but you will know that had crashed only if you will try to make a phone call or if you try to access the data connection.

---------- Post added at 09:05 AM ---------- Previous post was at 08:55 AM ----------

The only way to avoid this bug is to keep the phone on 2g connection and use 3g only when needed or use the maniac103 CM7 build until the devs implement the bp panic in their Rom's.

And I don't think anymore that is a software problem because I had changed the radio on my defy and others RIL related files, baseband but nothing. I think 90% that is a hardware problem.

Guys one news

I have installed the cyanmobile X by Fuzz(because is having the bp panic daemon).

The default governor was on-demand and RIL panic after 12h. Changed it to boosted, booted in Rom and I had RIL panic after each boot, changed the governor to Smartass no more RIL panic for now.

I'm trying with this new method maybe this is the problem.

I will try every governor from this Rom maybe one of them solves the RIL panic problem.

I tried with Wi-Fi on all the time for 48h and no RIL bug. Seems that the problem is having something to do with the 3g data connection not with the 3g network. I will test more and I will report.:)

[Defy Q&A, Help & Troubleshooting] ktmbikerman:
I tried with Wi-Fi on all the time too... didn't work for me. The only way I can be sure of a good connection is by leaving data on 3g only.

[Defy Q&A, Help & Troubleshooting] Max82it:
Re: Re: [BUG] CM9/CM10 Data connectivity bug - unFIXED, it seems

After 5 days in 2g mode without RIL problems, I agree that 3g data connection is the problem.

Enabling 3g mode, the data connectivity stop working and the signal breakdown (despite the signal streght icon continue showing 3g and the meter still remain blue)

In my case only a manual reboot temporaly solve the problem.

I suppose there are two possibile motivations:

1. absence of SlugZer0 patch in the last versions of CM10 by Quark

2. SlugZer0 patch is present but it's unable to reset the connection in particular defy+ models (like mine, maybe for a specific HW problem)

[Defy Q&A, Help & Troubleshooting] DroidConvert:
I downgraded to CM7.2 after having been on CM10 for several months hoping to solve the battery problems, lag, and the dreaded RIL bug.

The lag was fixed but the battery problems and connectivity issues remained. The connectivity issues had gotten so bad that I needed to reboot my phone every few hours in order to be able to receive calls and have a data connection. I was literally ready to smash this phone to pieces.

Until I got a new SIM card.

I have not had a single data connection drop or an instance where the phone cannot make or receive calls, for almost two weeks now. Also, my battery lasts me almost two days! Yeah, before I got the new SIM, it lasted about 10 hours.

Finally I have a proper, working phone. I do still miss CM10 though, perhaps I'll upgrade again in the future.
[Defy Q&A, Help & Troubleshooting] cyrusct82:

I don't think that this solves the problem because the RIL bug is on all roms even on stock roms.

[Defy Q&A, Help & Troubleshooting] robiwan kenobi:
I do agree with you entirely . And I have also tried different sim cards on my SOC MB525 with no success.

Regards the other provider I have used actually the O2 PAYG card and have had no ril problems, but couldn't tested it for long time - I'm stuck with Voda pay monthly.
[Defy Q&A, Help & Troubleshooting] cyrusct82:
Guys I think that the problem is definitely from the network operator.

Searching the web to see what frequencies uses my network and I have found a communicate dated 24.09.2012 (approx. the date my problems appeared) that says they are enabling 4G connection and they want to free the 900Mhz band. This seems to me that this is the problem because I used till now basebands with 900/2100Mhz(all from Europe). Now I have changed the baseband with China 850/2100Mhz. Until now every thing is ok I will report later if I have problems with RIL or not. (Data enabled again all the time).
[Defy Q&A, Help & Troubleshooting] ktmbikerman:
Very interesting...
[Defy Q&A, Help & Troubleshooting] Max82it:
I'm trying the same using America - USA Baseband 850/1900/2100Mhz, but in this case the 3G data connection doesn't work. The top right icon show only an 'E' - Edge and not an 'H' - HSDPA.

If I change to China 850/2100 Mhz the data connection seems work and the speed connection with Speedtest is really good.

So, we are waiting to see if this solve the problem :cowboy:
[Defy Q&A, Help & Troubleshooting] cyrusct82:
Or you can use south Korea is using only 2100 freq.
[Defy Q&A, Help & Troubleshooting] cyrusct82:
I think that the RIL bug comes in when the phone is forced to switch from one freq. to another (2100 to 900 and back). Using 850 instead of 900 forces the phone to use only 2100 band.
[Defy Q&A, Help & Troubleshooting] Max82it:

[Defy Q&A, Help & Troubleshooting] cristianosite:
After a few experiments, I would like to share my experience with the so called RIL bug and my conclusions.

1. I have experienced this bug in my Defy using a lot of different ROMS. Since stock rom and also in CM7, CM9 and CM10 by Quarx and/or Epsylon3. So my conclusion was, at least in my case, that my bug was not related to the ROM.

2. I bought a new battery, and the bug persists.

3. The bug has appeared last year, in Brazil, using the TIM mobile Sim Card, about 5 years old. Last month, I went to Europe and I spent 3 weeks between Germany and France, using a SIM Card from the German carrier BlauWorld, bought 3 years ago, and the bug has just disappeared. When I moved back to Brazil, I bought a new TIM Mobile SIM Card, keeping the same mobile number, and I am using it since 2 weeks with no bug. So, this leads me to conclude that, in my case, the bug is related to the SIM Card versions, or even a combination of the SIM Card versions and the network.

Best wishes,

The workaround is already implemented by Quarx in it's rom's and is done only by reboot the phone. This workaround is also in stock rom's but without warning.

Data bug work around

I had recently switched my service provider as they didn't have 3G. I started facing this telephony problem with my new provider. It was very irritating as it happened every other hour and if I was not aware then it reboots and get stuck at system menu and then drain the battery. Yesterday, I tried changing the mode from complete 3G to 2G+3G, and it has worked very well for me. This has reduced my reboots to once a day (I think), without losing speed. Which I am ok with. Some how I feel it may not be HW issue but a software one where switching Network modes has not been handled properly. I may be wrong ofcourse

Fixed the error in telephony layer restart

Hi all,

I bought a Motorola Defy second hand with a broken screen and it was fine for a month until I replaced the screen and back housing. After I did this I started getting the error and restarts. Turns out that the connections on the logic board weren't connecting properly to the points on the back housing that I changed over. I also cleaned the sim card contacts but am certain it is because of the connection points inside. I cleaned them and lined them up better.

Does this bug only apply to CM9, or to CM7.2 as well? I'm currently using CM7.2 RC3 and I face constant data disconnects. My phone is pretty much useless at the moment, so I really need to find a ROM without this issue.

@OP

What is a virtual network, which it seems you and many other posters report to be using? Is 8ta roaming on MTN's network, for example, considered to be virtual?

Also, might the issue not be with certain networks? Or have this been ruled out? I'm using MTN at the moment. I'll post my details as requested in the original post if this bug applies to CM7.2 too.

Hello Viva_SA

The bug apears to affect virtual mobile networks more than others, although som have commented that they also have issues and are not on a virtual network.

I am on Red Bull Mobile which piggybacks off Cell C, 8ta is a virtual network that piggybacks off MTN (EDIT).

My wife's phone is also on CM9 and has no problem, connected to Cell C.

I have heard that some users on CM7 are affected too, but I'm not too sure if it is related. It might be worth posting you APN info as I think having a URL and not just "Internet" might be related too.

Things that work/do not work:

- Changing APN type: does not change behaviour

- Saving APN causing reconnection: causes data to be active again but for a short time.

- Change of baseband: Perhaps it is also linked to the location I was in, but I was working in another location with the baseband set to the following:

Europe

Central Europe

3.4.x

It resulted in the connection lasting longer. However, since the problem is back again, I am wondering if it was the restart of the phone which did something that kept the problem at bay for a longer period.
