Imate Jamin GSM Band - JAMin, XDA Neo, S200 Software Upgrading

Hello everyone........first of all, I would like to thank everyone who is contributing to help others......keep up the good work..
I have seen many topics but couldn't find the answer to my problem......
Actually, I have an I-mate JaMin(G4) with radio rom 2.47.21........I m recieving full signals from network operator with band GSM 900......but not from any other operators.....like GSM 1800...GSM 1900......GSM 850......
Is that a software problem........or a hardware problem........
Can the problem be solved by upgrading radio rom....or firmware.....
THANKS IN ADVANCE..........

Hello!
Well firsth of all how do you know that your phone find and register only 800MZH signals?That's weird because as I know GSM/UMTS providers do not enable phone receivers to shov actual frequency...But anyway I had another problem...When I had NOKIA 7710 I only had signal when I was at the bacyard...When I came into house the signal was very poor or no signal at all...So I tought the house was the problem,but what's interesting when I went to basement,the singnal returned to full...No idea what was the problem so I sold it and bought my lovely Prophet...It works super...So,buy yourself prophet and problems will go off

But i've already got a prophet...I mean its JAMIN........Can anybody please help me out........plz

My friend,try installing new OS...
If that doesn't work,than you've got Hardware problem...
Best idea is to contact local service and give it to repair...
I don't know what else to say because this is a really strange problem....
Greetings!

OK.....lets see.............Thanks for the help Akix........

GSM Signal Receiption Issue

Just wanted to ask, if anyone else has had problems with their Polaris not receiving GSM signals ?
I have a HTC TC and it shows weak signal reception in an area where I know there is full signal strength available (tested it with couple of other mobile phones and they all showed "full signal strength" = 5 "signal strength bars").
Is the TC known to be "weak" when it comes to receiving GSM signals (which I would find hard to believe) ?
Regards,
Andreas
EDIT: The TC has started to not respond to the "ON" button at times, have to to a reset in order to get it to "wake up" again. Looks like I got a dud ...
Just wondering ... is there a trend becoming visible here ?
New phone, less reception ?
Cheers,
Andreas
It may be sensible to add comments as to how much improved or how much worse the receiption is ...
As I already stated, I basically am no longer able to reliably make calls on my mobile phone because the TC gets such bad reception
How about your experience ? Are you getting "bad" sound (noise, crackling etc.) or drop outs ?
Or is the quality of the connection OK, but you are not getting a signal to actually make calls ?
Cheers,
Andreas
Are you in GSM only mode, or does it not switch from 3G to GSM?

No, my reception was poor from the "get go" ...
I did hard spl and loaded some other ROM to test, but it did not get any better ...

By your signature I see that you've upgraded to a Bepe rom and upgraded your radio. Please check this thread:
Reception Difficulties
You've updated your Radio, now you're screwed
Hi:
I'm using the 1.64.08.21 radio with Bepe .067 Premium rom and the system is doing ok with the exception that because I do not have 3G yet in my area, I have a hard time connecting to AT&T and it take a long time. When I travel to a 3G area, the phone smokes.

Darn ... sorry ... forgot to update my signature
I currently have a TC with the original ROMs.
But from what I see so far, nearly 45% report a reception that is worse than with their old phones. Not good, is it ?

Andreas

When on 3G it's impossible to make/receive phone calls

Hello, I've searched through the forum but I wasn't able to find a similar problem.
When my Polaris is connected to 3G it's impossible to:
_make/receive phone calls
_send/receive SMS
I've tried with several SIM cards, even with one that I use on 3G every day on another phone. No way to make my Polaris work.
The only way to phone is to force it to connect to GSM (G icon), doing this I can phone and send sms normally. It also works when connected to Edge (E icon).
I have an original italian ROM:
R 1.58.21.23
G 25.65.30.04H
D 1.25.00.00
Same problem is being reported by other 3 italian users, we all have the same R 1.58.21.23.
Any of you have any idea on how to fix the problem?
Do you think that flashing Murata radio rom could help?
Many thanks in advance. I don't know what to do.
same problen in spain
I have the same problem in South of Spain. In 2G (GSM) yes, but in 3G is impossible today. Anybody else?
I have the same Radio, Protocol version... And works fine. 2 out, 1 to go, I'd say there's a problem whith the original ITA ROM...
Did you try a Hard Reset to fix it? If you did was the fix only temporary? If so, there are two options...
warranty
Cooked ROM
Thanks for the answers!
Yes unfortunately even after hard-reset it doesn't work.
Apparently there are different 1.58.21.23 Radios according to this thread http://forum.xda-developers.com/showthread.php?p=2171454#post2171454
I was wondering if it's worth to try the "Murata 1.58.21.23 Radio" which seems to be an official HTC Radio issued for russian customers and which seems to solve reception problems.
I could try it and if it doesn't work I could go back to the original 1.58 and original SPL.
I'm a little scared to install a cooked ROM instead, I bought the device 1 month ago, I'm still in warranty.
Thanks
I had the same problem and found only one solution: warranty replacement
HTC replaced my Cruise's motherboard and now it is working like a charme.
I'm living in Rome, Italy and they took 2 weeks for replacement.
Good luck!
At this point I'll send the device back to HTC for warranty replacement, I'll call them tomorrow. Thanks Cloudlord!
Ciao
Search the other forums (e.g. Kaiser/TyTN II) for the 3G problem. I had it with a Kaiser and they also told me that a motherboard replacement was needed. I changed the unit to a TC which did not have the problem.
The problem seems more than common...

WM6 Upgrade now No signal Radio bad?

I have tried several radio roms to try and fix the problem but I always get the icon looking for a signal never detects GPRS or any signal does this mean I have a bad radio? I have the PN Antenna,AFM50-000015,ACON where can I get one? Any help would be great!
Do you get normal phone coverage? If so, have you set up GPRS correctly for your network?
Keyboard for WM6
Dear XDA peeps any idea where i can download a i-phone like keyboard( directly on my ppc) that has all the new tweaks (pop up letter, skin...)
Looked all over but nothing.....
Thanks

Thanks for the reply, Not sure if I have the GPRS settings correct, went through all of them and changed some things, let the device sit for hours but still no signal.. I'm lost
Does the SIM work in other cellphones?
Cuz I have a SIM here that's expired and all it does when popped into any phone is try search for signal which it doesn't find any of course.
Had same issue...
AT&T/Cingular USA primarily uses 850MHz signal; 1900MHz is concentrated in larger cities. However, T-Mobile uses 1900MHz...You may have to switch. I had the same problem and found T-Mobile as my solution. I Hope this helps...

Have a look on Dev & Hack section, perhaps there you can find what you need.

Low Signal

Hi,
I have a problem in my Xperia handset, its dropping signals sometimes and even I can,t make calls and also my friends are telling me they cant reach me. I tried switch off HSDPA and 3G, and seems it solved the issue. Is this a really firmware issue or a hardware issue. Coz if its a hardware issue I need to change the device. Im so thankful if anyone can give me an advice..
Thanx,
Sha
it also could be an issue with you not being in a well covered place
for the frequencies your phone support ?
Don't know a lot about your phone, but it should be possible to flash another radio version, like all the other windows mobile phones.
It could do the trick.
It really helped a lot on my Diamond.
Some radios work better than others for different pdas.
Also, where do you live?

GSM radio signal problem

Hi all,
I have a strange problem with my Polaris - when I drive my car and talk over the phone, it looses coverage and the conversation is being dropped. I think this happens when it changes the cells from 3G to 2G.
I used to have the problem with the original Windows Mobile and now also with WM 6.1 - the official ROM from HTC.
ROM version: 3.13.405.0 WWE
ROM date: 08/21/08
Radio version: 1.59.42.15
Protocol version: 25.85.30.07H
I have never tried to flash it with a "cooked" ROM. Do you think some of the ROM releases here will fix this issue?
I just want the problem fixed, so I will be thankful for every suggestion on how to do this!
Thank you in advance!
Regards!
Hmmm.... I guess it could be hardware error.
I have same ROM and I don't have such issue. My Polaris is also almost constantly switching 2G/3G (regarding changing coverage).

I am sure about that, Bodisson! I have a friend that has no problem with it also.
Maybe it is a hardware issue but I have no idea what to do in order to fix the problem. I bought the phone from eBay and do not have a valid warranty, so I do not know what are my options now, except to try changing different ROMs and see if I find a "magical" one that fixes the problem...
Bodisson, thank you for your response!
Any other suggestions?!
I have similar problem. Got my polaris a week ago (new) and had few droped calls when i'm in my bedroom.
Rom version 1.28.405.3WWE
Radio 1.58.25.14
Phone indicated bad signal reception (2 bars), but when it loses 3g coverage, it gets excellent reception (4 bars). So i changed phone settings and in the band tab choose GSM (i use GSM anyway) instead of Auto for my network type. No dropped calls since then (hope it stays that way ).
I'm new to the game to, but if this doesn't work for you or you need 3g, i guess you could try updating your radio. This could solve your problem (or worsen it, depends on the version people say )
Hope i helped. Ivan
@ Ivan: Is your ROM WM 6.0?
Because original poster and me have WM 6.1. And stuff happening to you happened to me while I was on WM 6.0.
Altough, I had to send my Polaris to service due to erratic BT and GPS behaviour. It resulted by changed motherboard...
Yes, my rom is 6.0. The solution i gave fixed the same problem for me on 6.0 so i figured he can try it...
I have had the problem using 6.0 also...
I am unable to try the suggested from ivanx method at the moment but as soon as I can, I will post the results here.
Unfortunately, as I said, my warranty is not valid in my country (Bulgaria), so the phone cannot go to an official service (I do not trust any other service here...).
Thank you guys!
