Unable to Make / Receive Calls on Jasjam

I bought my Jasjam 5 days ago. I am having a problem that sometimes people cannot call me. When they make an attempt to call me they get the message that the phone is off-line.
When the phone is in this state I cannot make calls either although I can see the "G" icon as well as the signal bars. The dialer shows "Dialing....." for a few seconds and then cuts out.
This does not happen all the time but say once or twice a day.
Things become okay when I soft reset my phone.
Just wanted to know if anyone else has experienced a similar problem and if there are any solutions. This is very annoying as you are so uncertain that you may not be accessible and you don't even know of that.
Thanks in advance for your help.
Kind Regards

I wonder whether it's worth trying to take it off automatic band selection and choosing GSM only for a day to see if it still has same issue.
Start>SettingsPersonal>Phone icon>Band and selecting GSM in both drop down boxes. In second drop down list it'll be the GSM band for your area or test on each to see which works.
I suggest the above just in case you have the dropped line due to auto swapping between GSM and UMTS issue.

I seem to have solved the problem of the radio silently switching itself off without me knowing and so risking unnoticed missed calls.
The ROM version supplied from the factory with my Jasjam (HT647xxx) is as follows:-
ROM Version: 1.31.305.2
ROM Date: 8th September 2006
Radio Version: 1.21.31.10
Protocol Version: 32.53.7020.01H
Ext ROM Version: 1.31.305.104
Bootloader Version:1.06
Strangely the I-Mate site at this point states the latest ROM available for download is:
ROM Version: 1.20.305.3
ROM Date: 21st July 2006
Radio Version: 1.07.03.10
Protocol Version: 32.41.1010.02H
Ext ROM Version: 1.20.305.104
Bootloader Version:1.04
So I flashed my Jasjam with the ROM of 21st July 2006 downloaded from the I-Mate site.
For the last two or three days since I have downgraded the ROM the problem of radio switching itself off seems to have disappeared.
Just wondering if I-Mate are aware of the problem with the ROM currently being shipped with new devices and so decided the keep the old ROM for download on their website.
I will continue checking and report if I see the problem reappearing.
I thought to share this information in case it is useful for any one of us.
Regards

Yeah, I have same problem with an Orange SPV M3100... Two different maintaince office said "we have no idea" in Hungary...
Please, If you have an idea, share with us...

I already changed the rom 6 times, to 6 different roms (official, boiled, WM5.0, 6.0, 6.1), but nothing happened... I already try to change radio rom only to a different and back to the original. But nothing...
The last service said "the hardware is ok", they measured everything.
The problem is that the phone connect to the tower, but after 1 minute lost the connection, but show me the full signal level and I'm unavailable. At the first call that I make it show me an "operation failed" message and reconnect...

I think it sounds more like a radio ROM issue than an OS ROM. I had similar issues until I found a radio ROM that worked for me.

Hi, thanks for your answer. I had change my OS ROM and Radio ROM to your settings
IPL 1.04/ SPL: Hard-SPL V7 2.10.OLIPRO
Radio 1.48.00.00
Rom Version:Josh's Manilla2D v15
But nothing...

Please help me, my Dopod 838 Pro has No GSM!

This sounds similar to the problem's I'm having with my Sony Ericsson X1. It started a couple of weeks ago, seemingly spontaneously. I had been running the same firmware (generic UK R3AA010) for quite a while with no problems (at least more than usual with the X1) but suddenly one day these symptoms show up:
People who try to call me get an "unavailable" tone. If they try again it works fine
If I try to call someone, it just silently fails the first time. If I try again it works fine
So it seems that the phone gets disconnected form the network somehow. It can't just be that the phone network looses track of where the phone is (in which cell), since it affects outgoing calls as well.
I've tried this with two different SIM cards from different operators with identical results.
I've tried a couple of other firmware versions with no help. If anyone can help with information on this I'd be very grateful.
There's no way I can use a phone that people can't reach me on, but I can't stand the thought of throwing a fairly expensive phone in the trash.

exactly same problem here. I figured out that switching off the phone function in comm manager and then switching it back on does the trick without soft-reset, but I don't need to explain to you how annoying it is... I've already changed 4 OS roms and 2 radio roms with no result... I'd appreciate any suggestion very much.

dropped jasjam

Jasjam dropped from hand. Even after the incident, the phone was working fine. but all of a sudden few days back, calls started dropping. initially thought a corrupted radio. accordingly updated the radio version from 1.2 to 1.4 series. Even replaced the wm5 by wm6. still the call drops. *The drops started a month after the phone dropped from hand. should it be fair to blame the incident solely for the call drops? but then again, even the updates are not working!*
Using VODAFONE postpaid. Region :India.
Changed the Band to GSM (900+1800)+ umts 2100
Has anyone faced the problem? shall i try my luck by updating the radio to even a higher version? whts the best radio stack for jasjam in vodafone (gsm 900+1800) india?

noup
dont upgrade the radio stack!!!!
Better to open your device and take a look of the anthena maybe its disconected due to the drop. dont upgrade radio.

Moved you over to General since this isn't really rom dev related.

Cannot call in/out with Full signal

I am in USA using AT&T with my HD. I could see full signal bar but I cannot make a call nor receive a call. Also, I cannot get data connection as well. But when I travel to HongKong, my phone works fine and also works great in China. It should bot be any hardware problem. Please help to solve this. Thanks~
Here are some info for my phone:

Data connection unstable - lost

Hello Optimus 7 owners,
My Optimus 7 already went in warrancy repair for the infamous "reboot issue" and now the problem is gone but... it seems that data connection is absolutely unstable. I wanted to understand if I'm the only one with this problem or if it's a common one.
The data connection constantly switch from max power H to one bar of G, then 3 bar of 3G, then one bar of H and so on without a rule and many times switching even to the "no signal" icon, then resuming in one second. (if it's unclear I can make a video and post it to youtube)
I'm on Vodafone Italy and it's not an operator signal issue because my wife phone (an old Motorola V3) don't has such strange Behavior, and my old HTC Touch HD worked as expected too!
That behaviour translate to an unstable data connection, many time I see timeouts or long wait time before data start to works in apps that use internet.
The strange thing is that if I speak with phone there seems to have no problem...
I'm alone or someone is in my same boat??? What do you think about this strange Behavior?
Here my versions:
SO version: 7.0.7392.0
Firmware version: 1.0.1.10
Hardware version: 1.0.0.0
Radio sw version: 1.0.1.10
Radio hardware version: 0.3.5.0
Bootloader version: 1.5.0.0
SOC processor version: 0.30.2.0
The phone has it's original firmware, I've never done strange things
Thank you in advance to all kind people that will answer

No one with data connection switching between 3G, H, G and no signal like me? I'm the one in the world with this problem??? I can't believe that...!

I have partly observed that behaviour on my set, I tend to have some signal issues as in always very few bars (say one or two) where others using same carrier have full connection.
Not sure if it's a firmware problem, read something about a pending fix from LG but I can't find the article anymore so it might have been bogus.
This can cause the phone to rapidly switch from 3G to E (Edge) to H at times.
It's not such a big problem for me so I guess I really don't think about it much.
/J

I'm thinking about sending my phone again to repair... :'(
Sent from my LG-E900 using Board Express

This is the same for me as well - i live in a bad signal area anyway which doesnt help but the phone will go from full signal to no signal back to decent signal.
A Dell Streak on the same network has much more stable signal.
Must say it has improved slightly in Mango although not that much

Well..... I don't know if I have the same issue. I work in a large building and I know I have a weak signal inside. So most of the day it stays on G, sometimes E if I just pull it out of my pocket from behind something.
The issue I have is that when I know there is a better connection, it doesn't seem to jump on it. I either have to go into the cellular selection in settings or simply reboot it and it will find, display, and fully use H connection. Which I am more than pleased with the performance.
Trouble is, both the office and the house have weak signals so as long as it's G or 3G I'm happy. The only time I get to H is if I'm traveling around town and get to play with it.

Posted problem to youtube
I've created a video on youtube that shows the problem as it occur. It's written in italian language but I'm sure you'll understand what's happening whitout problems
Please whatch the video and tell me if you have the same/similar issue as I have (switching between 3G and H with very unstable data transfer / stuck)

This is my first post so I would like to greet the entire XDA community.
I'm facing the same issue (instable 3G connection). With my previous smartphone, a Sony Experia X1 with Win Mobile 6.5 + Manila ROM (thanks XDA!!), 3G connection works like a charm. I think that poor connection performance have as side effect the excessive battery drain (12-16 hr with push email disabled).

I have a similar issue. I live in spain, and it seems that the connection here is an option.
Anyways, like I said, the connection is bad, but many times, the phone switches off the data connection alone for a randoom time. then it comes again.
I used the Word switch off, because, although data connection is off, I can make and recieve calls.
This makes me obviously nervious, because I don't want to call trough phone-line, I want to call through Tango!!!! and chat through whatsapp instead of sms

Can you post system info of your LG Optimus 7?
Particularly OS version, brand and SIM operator. I wonder if it happens when brand of smartphone and SIM are different.
Thanks.

If you want mine you can read them in my signature. Previously I had TIM-IT ROM with Vodafone IT SIM and I had same problem. Today I have reflashed with Vodafone IT ROM and a Vodafone IT SIM, same problem.
I don't know what to do... I don't believe a LG service can fix the problem.... Or yes? Is anyone that sent device to service for that problem??? Please tell us your story!

This is very noticeable on mine - so much so im using a Wildfire S that holds signal perfectly well in the same place (not as good a phone though). Will try and see if locking it to 3G only will help.
Hopefully LG release a firmware update for this.

Some new considerations. Usually I work in an office with poor 3G signal strength (max 2 bars) where I have instable data connection (and voice calls too). Yesterday I worked all day long in another location with good 3G signal strength (at least 4 bars) and I haven't had any connection problem: email (Exchange and Gmail accounts), IE, Market Place etc. always available.
Now I am at my usual office and once again I have an instable data connection. No reset/restart/switch off/fw update in the last three days.
Is it possible that it is only a "bad reception" issue?
How many bars do you have when instable data connection issue occurs?

It's very difficult to tell you how much signal there is at my home (where I've recorded the youtube video) because my LG Optimus 7 is reporting a value from 0 to 5 bars.... Normally it stays at 4 of 5, if I configure not to use 3G it stays to 5 of 5 bars. In My Nokia E65 I've used to compare loading times, the signal is at 100% of the bar.
I really can't understand what's going on with my device... The main thing is that I cannot understand if it's a common device problem or only my device problem. Maybe the second? If that's the case I'll send to repair for the second time my phone (other 3 weeks without phone... ahrg!)

I've the same problems with my LG Optimus 7. My common carrier is E-Plus/base here in germany. Extreme fluctuating signal (switching between 3G, H and E in less than 2 seconds) when starting a "online-app" and it doesn't depend on the location (indoor/outdoor). The Data-Rate is poor and most times i have the "no-signal-sign" in the upper left, but the strange thing is, i can buzz so. without problems...
Looks like a poor programmed signal-display.

no signal
Yes, in fact I noticed too, in these days, that sometimes I'm stuck with "no signal" symbol even if I can ring to my phone... I've also seen the no signal symbol while communicating from internet (yes, wifi was off...) I think the LG driver is very poor, in fact the battery too has the problem that it doesn't update if you don't turn off the device.
I can accept that the signal symbol is not realistic but not that data doesn't come in/out! It's terrible.

I have the issue, I'm from Argentina and I have the same problem, indoor o outdoor it's the same. LG E900H.

I do a Factory reset yesterday and I haven´t this issue anymore. I do it for the battery life, and now I don´t have both issue. May be the unstable connection was the battery problem because the device is looking for signal everytime.
Of course I´m not sure but it´s possible. Good Luck

I have the same issue too.
Try to open MFG app and then select:
7. Engineer Menu
4. Modem settings
2. Band Settings
Select WCDMA Only (GSM only may help also) and reboot phone.

Same here
I'm with Vodafone-it and have the same issue, and even worst: sometimes I loose my connection with Wi-fi, too, at my home, while all other devices continue working.

GSM Voice abroad

Hi!
I have two Droid pro phones from Verizon.
They are both unlocked to use abroad and have latest system update - 4.6.8.XT610.Verizon.en.US.
Baseband version: N_01.81.00R.
I am using phones on KCell (Kazakhstan local telecom provider) which operates on 900/2100 frequencies.
So I see very strange behaviour with this phones:
While the phone on GSM frequency I can't hear anything - absolute silence during a call while on GSM, or I can hear for a first few seconds (1-3) and then again - nothing.
I can hear only signals from numbers on Dialpad when I press it.
At the same time, if the phone on UMTS band (I see that because 3G icon is shown) I can talk easily, no problem at all.
Tested on both phones - same situation.
Tested on other providers (Beeline) - same.
Can anyone can tell, what all this mean and how can I solve this?
Does anyone experienced similar problem?
Thank you!

I use a Motorola Droid pro 4.6.8.XT610.Verizon.en.US with MTS Samara (Russia), no such problem, but there is a problem with the quality of the signal, the signal is weak, even in the GSM mode.

I have the same problem in Italy with some cells... I have seen this issue only in a few zones/cells, with only TIM (my ex operator), with other operator i don't have any issue.... I think that is issue between your/my operator with old cells and our phones...
And it is impossible to correct....
But You can send/recive sms and use internet...

Thank's a lot for the answers!
Do you know is Cyanogen ROM or baseband switch can help me?

No... I'm sorry...

Probably your providers are not using some voice codecs, that Droid supports. Call to the call center and escalate issue - tell them to escalate to the technical team to check codec compatibility in the network.

Try the Baseband Switcher for Defy.
Then select the baseband for your country your are in.,
Probably the baseband in your country is not match with Verizon's
My network provider in Hong Kong is CSL, and when I received this Verizon,
voice calls on 3G can be dialed out but no voice.
Once i tried this lit thing for Defy, calls were fine.

Did you installed baseband switcher on Droid Pro?
I just installed it and it crashes at start.
Can you give some guidance on install process? may be need something special ...
Thank you!

Hello,
I have a similar experience: in Slovenia, on Simobil, voice works reliably only on GSM. On 3G, there is no voice on outgoing calls. Data works on GSM and 3G.
I also have Baseband version: N_01.81.00R.
And Defy Baseband Switcher also crashes on start :b

i really don't know... but if you try to put Argentinian's sbf, wait 48 hours without battery, it's possible that you can start your phone in a really gsm phone...
seeing other posts you can find another user that was able to do this procedure from european to american's sbf...
maybe?

Hey,
I also use the phone in Kazakhstan under ACTIV network and have the similar problem. There was no such problem just before a month now. Maybe our provider changed the frequencies or smth. It really bugs me out((.Have you tried to use the phone under Pathword network? lets try to solve this problem since we both are using the phone under same provider.

Yes I have it installed on my DP,
if it crashes, it means the baseband selected is not suitable.
Remove Sim to boot up, change basband back to default, and reinsert Sim to boot and retry.
however, the improvement which I observed on my phone,
Im not sure if that was brought by the baseband switcher or just a random network issue, since I have no technical background. Just the phone vendor who sold me this 2nd hand handset told me to try, and a coincidence it worked after the installation.
* sorry for the late reply

Hey Kanabi!
How did you deal with the problem?Did you make it work?I've tried the Baseband switcher.it was installed but no help as such,there is still no voice on gsm network.
