Phone loses connection!!! Please read!

Hey all, I have a little (or a big) problem. It is so, that my phone sometimes loses connection. Than I can't call, send messages, go on the internet. So now to my question. Does anyone has/had the problem, and is/was able to solve it?
I wouldn't like to give my phone to samsung, because my imei corrupted (I don't have a backup of my /efs folder), I have flashed several times, and I rooted it several times XD and I don't have a backup of my orange fw (I live in Austria).
So please help me (if you can)!
best wishes

WHich version do you have? Is there a specific time when phone loses connection?
I had connection loss problem and that was related to mobile internet. You can try to disable mobile internet and check.
For Original ROM, go to samfirmware.com and download the original ROM, update your phone to orignal ROM and go to samsung service center and tell them about IMEI loss. Just show that you dont know anything

I have lestatious v1.7. I know samfirmware, but there is not a version for orange branded gt i5801^^ but ty for your quick answer^^

sometimes i get disconnected... what i do is go into the plane mode and come back out... connection restored...
It started doing this after i got my mainboard replaced... so could it be hardware related?

It happens with me also sometimes. Going into airplane mode and coming back doesn't help. Restarting doesn't help. Replacing sim doesn't help. Even inserting another sim doesn't help. Only fix I have found is walking over to a different area physically. Atleast about a kilometer or so and it latches on to the signal.

Hey check the providers column in samfirmware.com.. The last box has the provider firmware you will get the orange firmware there I have seen.

yeah this would happen to me...bdw see that the mobile tracker is off...n plus wenever not required turn ur data service off...it will be off much help...!
Atleast this solved my prob
On Kyrillos 3.0beta

when i was on airtel i used to have calldrops....
now i switched to tata dococmo,call drops are gone but sometimes while talking signal goes off ,also i get a small message "refreshing sim data" and i cant use internet or any other signal related services for not more than 2 minutes,this happens about 10 times a day....
but still sometimes i lose signal[shows a diffrent icon instead of the general signal icon] which lasts for long time[once it happened for 2 days]....[this has happnd only 2 times]
is there any solution to this problem...like falshing with rom or official update

[Q] WiFi issues on almost all ROMs - MB525 red lens

Hi All,
Since I got my DEFY I have WiFi problems. This issue only exists when WiFI has WPA/WPA2 PSK authorisation.
It is going like this: I connect over the wifi. Then connection works fine, I am able to browse www, check the emails etc, and after few seconds, minutes the connection stops working but still exist. I try to reconnect several times. Defy shows that is connected but nothing works fine. Internet apps or Market gives a message like the time is up, connection lost. I have to forget the conection in settings or reset device to get it working properly, but not for long.
And the thing is that there is only ONE ROM that works fine with WiFi on my DEFY. This is Cyanogenmod-7.1.0-RC1. Other ROMs have same issues. Doesn't mater if it is Cyanogen mod 7.1 stable or any MIUI or MS2Ginger. I tried almost all roms but nothing helped. So I had to go back to CM7.1.0-RC1.
Do you know what should I do to make WiFi working fine on other roms?
greetings,
Gregory
p.s.
Please, just don't tell me that I should change authorisation on WiFi router. This is not a solution for me, because I use WiFi in a lot different places.

Same problem
Hi,
I have the same problem with my Defy since a few months, no solutions!

I have the *EXACT* same issue. Was about to roll back to stock and send it in for repair, glad I found your post! I'll install the ROM you suggested and keep hoping this gets fixed

just fixed my wifi issue for the second time. If there are to many remembered networks no more wifi. You can turn it on but it cant find any. delete all remembered networks and back on line. that is the only conectivity problem I have ever had after months of cm7

I think that's a different problem than we're having. It is finding the network just fine (and connecting) in our case. It's just that internet connectivity refuses to work after a few minutes, forcing us to disconnect-reconnect to get it working again
@OP: Thanks a lot! The ROM you mentioned does indeed not have this problem. It's not as stable as some of the more recent roms though, think I'll still be forced to revert to stock

i had exactly that problem with my first defy, no solution man, i send it to warranty and they give me other

maybe changing the regulatory domain channels from 11 to 14 could help. this option is hidden by default, you have to enable it: change the value of 'ro.debuggable' from 0 to 1 in /system/bootmenu/config/default.prop, save and reboot. after that, the regulatory domain setting will be shown in settings/wireless/wifi/advanced. simply change it to 14 channels.

Thank you for the suggestion! Just tried this, didn't resolve the issue sadly
I'm looking into rolling back to a stock Froyo rom but the information is scattered all over the place, I'm having a hard time figuring out if it's possible, and if so, how ;/

Anyone have any more ideas? ;/

OK, maybe I just passed the signpost but... do you still have the problem if you set your "select network" setting to 3G only?
I ask because (and it may be different on my phone as I am USA, stock ROM with wifi calling) if you go into the INFO menu > phone information > set preferred network type, mine toggles between three radio preferences: "GSM only" (when wifi is active), "GSM auto (prl)" and -- if I set for 3G Only, "WCDMA only".
I have noticed that when "select network" setting is at automatic (or 2G only) it often has trouble transitioning from cell to wifi. And, when wifi is an issue, I find that "GSM auto (prl)" has been selected (which on my USA phone prevents wifi connection). However, it seems to have no issue whatsoever transitioning from "WCDMA only" (3G only) to "GSM only", which on my phone then allows wifi connection. Again, this is a wifi calling phone so may be different.

Yep, same here BUT ! I get root browser, found my build.prop and change wifi chanells first time for 14 and it didnt help so i try other and my wifi works in 100% with 13 chanells. Try it

This is a widely know problem, many people are affected more or less. I'm also having nerve-blowing times with wifi sucking all over... Stock Froyo (and now Cyanogen 7.2) seems to be a bit more stable, sometimes everything is fine for a few hours, all downloads go lightning fast - and then suddenly things are screwed up. I tried a lot of MIUI releases as I like it most. MIUI seemed the most problematic so far. I don't know what is the cause, new stock Motorola Gingerbread ROM versions also have this issue (except one I think - look it up in the forum).
Agree, bothering with the router is not a solution. My Nokia E51, my EeePC, my girlfriend's Omnia and Lifebook - all work perfectly with all the four routers we use frequently. Not a single glitch - everything is stable and nice, except Defy.
I don't think is a hardware problem with certain devices, it seems more to do with the way Defy handles wireless connections.
Anyway, it's frustrating but CM7.2 and CEE Froyo gives a bit better experience than others.

No, problem still persists. Sometimes it works flawlessly for hours. Then... suddenly screwed :S In some cases a "switch wifi on/off" workout can help but not always.

Which Froyo version do you use? A few times this wifi-bug occured also under Froyo. I'm thinking about going back myself, as Froyo is the only acceptable release to record hiccups-free videos

[Q] defy signal problem

Hi all i got a defy green lense and having signal problems.
I have been using cm7 and now cm7.2 since using non stock roms my signal has been playing up majorly.
Sometimes cant get a signal other times i'll get a signal but only hold for a while
Most annoying the signal "unlocks" when the screen locks and then takes ages to lock back in again.
3g problems too.
I have tried all the basebands and different sim cards and networks but still the same (ok when i put into another phone).
I have checked inside the phone (had to replace ear piece again) and nothing is broken or dirty.
i did read somewhere that it could be the radio files on the phone but i thought baseband swithcer did this?
Any help would be great as its getting annoying now also i noticed wifi locks out sometimes too when screen in locked?

WOW this prob just hit my phone this morning.
i went to sleep last night and everything was fine
woke up this morning and had no data and my defy says Emergencies calls only.
i tried putting my Sim into a g2 and works perfect. tried resetting the defy and changing the base band and nothing... only one that lets me make calls and gives me 2g is Australia base band. i even flashed a fresh sbf and im still having the same issues.
if anyone out there knows how to fix this issue please let me know i really need my 3g back.

I'm not too worried about the 3g it's more the annoyance of the signal cutting in and out.
Is there a way can change the radio files on the phone without using Baseband switcher so I know it's actually changed then and not looking at lots of files?

Tried the baseband already, put stock rom on and the signal is better nopt switching on and off so why does this happen on cm7 etc?

Just an update on this...
Flashed phone to cee deblur stock rom and signal was OK so worked out it must be a software rather than hardware issue.
So using the PC method I flashed the phone 3 times and wiped all the data each time.
After that the signal was still OK so I install 2ndinst and loaded cm9 cm9 kernel and gapps. Wiped data and the phone has been fine apart from 2 lock ups. I'm getting 3g and the signal is not being lost. After installing cm9 I also installed rom updater ,after 1st reboot it updated Android and now my camera green lenses works too not 100% quality but that's what my dslr is for! So for people getting the signal being lost abd no 3g problem try a stock rom a few times and wiping phone then custom rom worked for me!

Czech republic signal issue
Hi,
I have signal problems too - Vodafone CZ user. When I have no signal uderground - when I go down by escalator signal just disappears. Its verry annoying in case of using mobil tickets.
Im using WajkIUI™ ROM based on MiuiAndroid 2.3.7 (GB) on Defy+.
Have you any sollution for this?
Thank you

I have the same problem. There is no signal in underground or even in elevator! I checked it with cm7 and whiterabbit. I think it doesn't depend on rom. But I believe it's software problem.

Problem in Base Bands
I have problems when I switch to 850-1900 frequencies, the ones that works in America, Argentina.
I tried everything, differents roms, stock roms for Arg carrries. APN are correct, Baseband selector for Defy is correct, set to Americas, argentina,
I bough this phone from ebay, it seems to have been designed for UK Ireland according to motorola support, I haven't reached the UK support because they're currently closed.
When I am in 900-2100 Bands the phone works perfect EXCEPT for 3G, H Connections that don't work at all.
Is it possible that this phone has a different hardware ? I read that it may can be solved with a new Base Band for America but how do I go with this?
Thanks

Hi, It looks like the problem I have and which is location dependent but for me 2G works better than 3G. It seems that the Defy or CM10 is not working good in circumstances were it switches from one network technique to another. Reboots I have:
Reboot after switching automatically Wifi on with Easy Profiles. Effectively it then shuts down 2G/3G because Wifi is switched on.
At my work where we have indoor coverage with 2G antenna's. Much less reboots there if I put the phone on 2G only.
Some reboots I can't explain
I log my reboots with reboot logger from the play store. Pictures in Play store are not English but app is in English. Handy app!
I did play with several basebands but in the end the default baseband for my location worked best (3.4.2-145 Central Europe). More frequent reboots with others or the went info flightmode spontaneous.
No solution but you could play with the following settings:
Settings - In Wireless & Networks: More - Mobile neworks:
National data roaming
GSM//UMTS Network preference
Use only 2G networks
I did not find a combination which ends rebooting once in a while (a little less than one time a day on average).

[Q] DefyPlus Root successful(?) 2g-GPRS messed up-Please Help
@Mods: If this thread is not placed appropriately kind move/merge as appropriate. I did try to search for this peculiar problem but was not successful. Thank you.
Hello everyone,
Today I pulled the trigger and rooted my Defy Plus inspite of all the misgivings I had about my ability to carry it off successfully. And in hindsight my misgivings seem to be very justified.
The details of my device are:
Build # 4.5.1-134_DFP-231 & Android ver 2.3.6
SBF : 45.0.2310.MB526.AsiaRetail.en.03
The rooting guide I followed was as per http://forum.xda-developers.com/showthread.php?t=1542956
Recommended SBF's were downloaded and the method outlined followed
The long and short of it is:
*Most likely the rooting has been successful - How do I know? Well I installed a screenshot application from Google which needs a rooted device and it said my device is rooted and it worked successfully.
* The problem? The problem is, my primary objective to root the phone was to enable some call recording app or the other to work and if that did not work go for WIUI GB or ICS custom ROM which if I understand correctly is configured to allow call recording. My data usage is minimal at best restricted to some emails , work related browsing when I am away from my office. For this I use a 2g connection and that suffices. However after the rooting if the network is set for 2g the device does not list my service provider, even if I do a manual search for service provider. The very same phone works flawlessly if I opt for automatic network selection and it defaults to 3g which I do not want due to cost implications.
Now is there a way to resolve this issue without rooting a custom rom? Or do I need to flash a custom Rom that to extricate myself from this mess? Or do I need to go back to factory settings using SBF the device is shipped with?
Thanks in advance for any help

Success - Baseband reset for India
I was facing the same issue , after rooting my phone as indicated in my earlier post.
Subsequent to that I installed WIUI Rom - the stable version - from here, and used the inbuilt Baseband utility to reset baseband for India. Issue resolved.

[Q] Help with data and GSM losses of connection

I own a Verizon Motorola Razr M, bought in ebay to an US seller. I am in Spain and I use Movistar SIM card
The phone came with stock JB 4.1.2, and therefore I could not unlock the bootloader.
I started using it, but it had a problem that I am not been able to solve so far: after some hours of use, with no problems with GSM and data connections, it suddenly looses both connections, although the signals on the status bar still appear. I take care that signals have gone when I take the phone to make a call or surf the web.
I have tried the following procedures:
Change the net settings to GSM/UMTS
I rooted the phone with motochopper 1.1.2 exploit
I installed Safestrap 3.12 in order to be able to install other available locked compatible roms.
I tried these roms, following this thread here in XDA: Clean ROM 1.0. Clean ROM 1.1, Barebone New Base, Stock Deodexed.SDswap-Locked & UnLocked BLs-xt907-9.8.1Q-94-1, but no luck. This last one uses the last radio, but no way.
I also installed the [PATCH][GUIDE] Patch to fully enable GSM on Verizon CDMA Android phones. I could only install it on Clean ROM 1.1 however. It has been impossible to install it on the other ROMS. In any case, no luck again with the patch installed. Here I had a big problem because as I still had these problems, I got into *#*#4636#*#* in the dialer, and touched the band selection option: suddenly, the net showed no signal more and I was unable to make it work again: I finally solved this by installing the stock firmware from here with RSD lite.
No way. I still have this problem and I can not use the phone. I have also tried with another SIM card, but the problem remains. It is a shame because when the connection works, the phone runs very well.
Any help would be very appreciated

The problem also seems to become worse with the use of the phone: at the beginning, coming from a factory reset, It can last some hours before the problem occurs. But since it happens from the first time, it happens more and more frequently and the phone can not be used any more. It seems that there could be a software issue.

Another try disabling fast dormancy
I´ve just disabled fast dormancy, because my operator Movistar apparently does not use this technology.
For this, I have modified 3 lines from build.prop system file, as indicated in another site.
The 3 lines are:
ro.mot.ds.fastdormancy.disable=true
telephony.lteOnCdmaDevice=0
ro.telephony.default_network=3
Having fast dormancy enabled when your operator does not support it, seems to drain battery, and could cause other problems. That´s why I´ve done this. I have used root explorer apk from Google store, it is free and it automatically creates a backup of build.prop file when you modify it.
I keep the fingers crossed, let´s see what happens.

Fast dormancy: yes but...
After some days using the phone with fast dormancy disabled (for this, I also added this line to build.prop: ro.ril.fast.dormancy.rule=0 ; I read this for ICS Roms, I do not know if this command is also valid for JB, any comment will be welcome), I still get some cuts (less I would say), but at least the phone tries to restart the connections. For this, I have also installed the apk from Google Play called 3g reconnect.
In any case, any comment would be appreciated.

Issue not solved
I still get data and voice disconnections when I use GSM/UMTS or only UMTS modes. They occur ransomly, and they also occur as soon as I use a WIFI connection. I can only use the phone on GSM only mode, which is frustrating.
Any advise?

I do not go near *#*#4636#*#* anymore. So tell me do you use that to make these changes (phone info is the app name).

Choosing GSM/UMTS or GSM only

Hello,
I have tried both: using *#*#4636#*#* or using the usual phone settings. Sometimes I have also checked that the changes made with the usual settings appeared also dialing *#*#4636#*#*.
Yesterday evening, I tried selecting global mode instead of GSM/UMTS and it seemed to work for some hours, but today morming, the problem occured again. So far, the unique way I have found to avoid connection cuts off is using GSM ONLY mode. I have to say that I have tried with 2 different SIM cards but the result is identical.

Did you select the 3 dot menu & mess with the "band" settings?

I did that once, and all the signals disappeared. I restored the phone with RSD Lite, that appeared to be the unique way to have again signals working. Now I do not even dare touching these 3 dots.

What booby a trap? How many step into!

I don´t know if I am understanding you. I did that once because I did not know what else should I do to solve the problem. I saw that there was the possibility to choose theoritically between US bands and Cellular, and I entered in that menu. It is not so stupid to try that if you have already tried 100 other ways.
In any case, anybody has an idea about how to solve this problem? I´m sure I am not the unique person having this issue with this phone.

You are saying the problem is now still there. Yet the radio partition is fixed. Please restate what has been fixed with the rsd flash & what remains unfixed.

Well I think I have fixed and solved the problem: I initially copied the APN settings I had with my previous HTC Sensation, because the phone operator was the same (MOVISTAR), the SIM card too, and I have not moved. In these APN settings, the proxy was "undefined" as well as the proxy gate. I wonder if the radio stucks looking for a proxy each time or whatever. I tried yesterday with completely different APN settings, with a concrete Proxy and a gate... and now I have not had any issue in the past 24 hours. I will still wait a couple of days to see if that was finally the reason.
Which in any case would be silly, because I just applied what was working OK with my sensation, but...

New APN settings: let´s see

After several days, the problem is still there. After setting new values in APN, it happens less often, but it still happens. I have to switch to GSM only mode.
2 days ago, I was surfing the net at quite high speed with no interruptions, for half an hour. I then shutted off the screen, on again some seconds later, and the connection was blocked, I had to restart the phone. It has to be a software issue.

I finally sold the phone
After concluding that I could never get rid of this problem, I sold the phone, informing that he would have to use mainly GSM only connection. Great phone otherwise, but with this issue.

This sounds like a Baseband Issue.
Europe I have found baseband:
sm_bp_101031.027.32.81P to be the most stable so far, with no H+ support though.
But most Carriers in Europe don't have H+ or LTE.
That baseband is part of build 9.8.1Q-66
Which can be all downloaded here:

The baseband from 98.16.1 had H+ support in Europe but connections dropped like crazy.
Same with 98.12.4, we remedied that with Aussie Radio at the time.
Maybe this may help some International users with Data and GSM Loss

I'm on 9.8.1Q-94-1(98.30.1.XT907.Verizon.en.US) and wanna use it in Germany. any experiences with the radio compared to the suggested one. Or is there another way to boost the performance of the razr m? Compared to my razr I the signal and data quality is really poor...
edit: my baseband-version is: SM_BP_101032.021.32.80P
edit2: ok... now i've flashed several basebands... and the behaviour of the phone is always the same... with the australian baseband of xt905 it wasn't possible to get an hspa-connection. dunno if its enough just to flash the radio-fw?!?!?
so is there an other way to get more stability in my region? i tried to flash the radio from razr hd retail germany. but i think the razr m don't like it when I fool around. actually I love the mobile, so i don't want to make it angry... your suggestions are very much appreciated...
