Greetings Friends,
I have been using a HTC P3400( Old Gene) for last 2 years. As a member here of the Gene forum( although an infrequent one) i have been flashing the various ROMs made my many talented people here. Please bear with me if this post seems inordinately long but i want to share complete details of the problem i am facing.
My peculiar problem started when i flashed my Gene with Krazy_about_technology's ROM SumitsProUsers6.5_v2_OldGene.exe. After a couple of days of using it, my Gene would perenially be searching the network to connect to it, without any success. After numerous resets, hard resets, running ghost images etc and unable to resolve the problem, i thought this was an issue with my Vodafone SIM. I got it replaced and the problem still persisted. Post that i flashed the ROM with numerous other ROMs( Mostly Krazys, I find them very useful- Thanks Krazy for sharing your beautiful works), but the problem would just not resolve. The phone would always show searching a network to connect. I could not use SMS, EDGE or any other feature of my service provider.
The issue threw up another interesting find when i was experimenting with various other GSM SIMs. I used an Airtel SIM and the Gene would work good. Then i tried with a BPL Mobile SIM and it works just as good. But the minute i insert a Vodafone SIM, mine or others, it would indicate searching a network, I would not be able to make or receive calls or sms or access any other feature.
I took the handset to a Vodafone center and even they were flummoxed. They couldnt find a solution. They used my SIM card on different handsets and it works.
They thought my handset was somehow only disabling/ blocking only a Vodafone network. They advised me to get in touch with HTC helpline.
I called them and after lenghty discussions, they confirmed this was the first time they had come across such an issue. They asked me to visit their nearest service center. I did . The result was the same. Even the service centre was flummoxed and asked me to see what would happen if i downgraded to WM5.
I did just that with a HTC stock WM5 ROM provided by Vukile in the forums. and gradually upgraded to Krazy's WM 6.1 v 2.5
The problem still persists. I have been asked to visit the service centre once they run some tests or do some research on the problem themselves on a WM 6.1 ROM
In the meantime, I am currently using my Gene with an Airtel SIM and its working perfectly. It just wont accept a Vodafone network. I am using my Vodafone SIM in a Nokia handset.
Could it be an issue with the Radio ROM version? If so, why did it work with other ROMs and still works with Airtel and BPL mobile SIMs?
Is it really true that somehow, my Gene is only blocking Vodafone networks???
Needless to add, i am not a newbie to the world of Flashing and have learnt my way through friends in the forum like Munrus, Ababrekar, Vukile, NJackal, Chayn( He used to make some great ROMs) etc for the past 2 years.
This problem has completely perplexed me and all the techies i know.
I am posting this here in the hope that some brainy chaps might just be able to figure this out.
Thanks for reading the post and for any remedy you can send my way.
Rest assured, i will be keeping this post updated if the service centre is able to come up with a solution.
Cheers!

Radio 2.71.90
Yes, there definately seems to be some issue with your Radio ROM. Its an older version anyways, mine is 2.79.90. Radio upgrading is simple, but finding the radio or dumping it from a phone is something i dont know.
I think the problem your phone is having is with one type of freqeuncy. In India, 3 frequencies are available : GSM900, GSM1800, and GSM1900. Most network use GSM1800 in most places and GSM900 in some places While Vodafone uses GSM900 in most places. I guess that is the reason why Vodafone sims are giving problem to you.
Two more things you can try are : If possible, using it in national roaming mode in some other state and Using some other number Vodafone sim. Try if it works. The site given below will give you an idea of what networks use what frequencies where :

Otherwise best is to let service center guys figure it out. They may replace the radio module completly or upgrade the Radio ROM, or Who knows, the whole phone itself

Yes, You seem to be right. Vodafone at GSM900 in Mumbai seems the odd man out. Maybe the Radio ROM is not working for GSM 900 and hence affecting only Vodafone connections.
Still does it explain why the same Radio ROM worked for all this while over so many flashes and failed to connect to one particular frequency suddenly?
I have been trying to get a Radio ROM dump to 2.79.90 to upgrade. No luck yet.
My phone is out of warranty a long time ago. So no chance of getting the whole phone replaced without burning my pockets!!!
Thanks for your inputs Krazy!

Hi I dont think this is a problem with vodafone in mumbai...
Because I am also in mumbai using the vodafone service and also having the same (02.71.90) version of radio.
I think you have made any mistakes while upgrading...
Still check with upgrading Radio ... Let us know the status
Bhushan,
Yes , you may be right. Maybe i did make some mistake while flashing 6.5
None of the links have any Radio ROMs and i havent specifically done any Radio ROM upgrade myself. The only time the Radio ROM changed was when i ran Olipro HSPL.
Has anyone tried out railwayplatform's method?
How many of us are actually using the 2.71.90 version? If I am the only one facing this problem, then most probably the cause would be a bad flashing or M/B issue.
Cheers!
loop mobile a.k.a bpl mobile work on 900mhz so i dont think you have problem with 900mhz network as per my infomation your mobile is more then two year old so i think it time to buy new ..
Ofcourse its old!
But Loop and Airtel work flawlessly still. Its just Vodafone that doesnt.So no real reason why to invest in a new handset now.
Besides Its slowdown time guys!!!
There is a 99% chance there is nothing wrong with the handset.
So i am very keen to see if this problem can be resolved.
Cheers!
Hmm.. this is strange, really strange. Have you tried some other Vodafone sim too? Maybe its just with that particular number? I am just guessing now.
Krazy,
Yes the problem persists for all Vodafone SIMs( mine as well as others).
Have tried it with Vodafone SIMs of myself, my wife's, 3 colleagues at work and 3 at the Vodafone care shop.
This problem has been exihibited for all Vodafone SIMs.
Got a thought from a buddy - All this while i have been flashing with my SIM inside the phone. Does this have anything to do with the problem?
Cheers!
I dont think so...

i dont think so flashing with the SIM inside the phone is causing the problem...and may be you need to visit a HTC service center and ask them to flash an official wm 5 with an updated radio rom and see if it works...just a suggestion...Hope this helps....Good luck mate...
Just a thought
I have flashed my poor Gene and now departed Vox how many times I don't know, and everytime the SIM was inside. So that wont be issue.
Just a thought, are you using Vodafone Prepaid? Because Vodafone, atleast in Kolkata still provide 16 K SIMs and earlier when I had a Vodafone Prepaid number, my Vox would reboot between calls or while browsing the contacts / msgs. This was told to me by the tech support at a nearby Vodafone store that it IS a issue with all sophisticated sets (actually its sort of forcing you to go for a post paid where you will get a 32 K SIM ). So, if you are a prepaid customer, then can you try some one's post paid vodafone SIM and let us know?
Sorry! Duplicate post.
Yes 16 K SIM might be an issue because 16 K Airtel SIM is also creating problems like call drops, people call u but u dont get a notification etc.
I read the same on HTC touch orkut forum.
same prob here
dear friends,
i have also faced same problem, but a little differently.
I am a idea, punjab (formerly SPICE) customer. while roaming in ghaziabad / kale khan/ okhla I found that my phone lost network. it kept on searching on and on.i tried hard and soft resets also. if i did it manually, it wont register, and by any means it gets registered to a network, then 100% sure, call wont make. two sims showed this problem, one- idea and vodafone. but the problem was found while roaming only. i didnt report this in forum as i didnt take it seriously. but seeing this post, i decided to report it to forum so that it can be rectified. its just a feedback, not a complaint.
To Addicted2xda,
I am using a Vodafone Postpaid SIM. All the Vodafone SIMs i tried were post paid SIMs. At Vodafone Care, the guys there tried with a dummy SIM. The problem persisted for all SIMs.
This is really giving me sleepless nights.
Any way i can delete all the data on the phone including all ROMs, like bring it to a pristine state and then start with HSPL and flash a new ROM?? Maybe this may correct the problem - Just shooting in the dark.
To Mehra, Thanks for your feedback.
To HTCP3400,
I had a HTC STock WM5 ROM provided by Vukile. I tried it also. But the stock ROM didnt change the Radio ROM version and the problem existed with it too.
Cheers!
Guys, do you feel this could happen because of the SPL change? I dont know whether SPL is responsibile for sim activities or not, bu I will definately search for it. Apart from that, there is nothing we have changed in the phone. I dont know, but these kind of things never happened with me. Ya one or two times, my phone lost network at some places and keep searching for it even though other phones were working fine, but on soft reset or just turning the radio on and off from comm manager worked everytime. Anyways, lets see waht can be done.

the problem has nothing to do with ur OS. Its linked with the Radio ROM.
Try diff versions of the Radio ROM which would go well with your network. For instance 3.21.90 rom solves the call drop issue on chennai airtel prepaid to an extent. So you ave gotta experiment with diff versions of radio rom n freeze on the one which would be better for ur network.
Hey vaibhav, can you post the Radio Roms that you have got. That would be good in case when one of us changes his network and gets this problem. Coz I searched for them but couldn''t find em anywhere.
Just wondering if anyone has seen or tried to develop a baseband switcher application like the one found here http://forum.xda-developers.com/showthread.php?t=1203297 so the Photon can work on all US/international CDMA/GSM networks?? Out of the box it has(CDMA 850/1900-GSM 850/900/1800/1900-WCDMA 850/1900/2100-Wimax 2500).. but no 1700 T-MO..I have a Photon but no use for it since im using T-Mobile..Perhaps unlocking and a baseband switcher would enable me to use this amazing phone on any US GSM network like my Moto Defy Ive been using this app and Itfunz for international travel and im amazed how well my phone works on almost every GSM band in the US and around the globe.....Anyone?? This Phone with Root,CM7 and a "working" baseband switcher would be untouchable!!
Im on sprint so no real need for the switcher but i would love to see this come to life. I can make my brother jealous and steal his sim card.
I would love that
I am in the Dominican Republic and have not been able to find any alternative baseband versions to flash, since 3G (850 Mhz Band) stopped working a few days ago.
I´ve reflashed to stock, tried different roms and kernels, but i guess if i can swith the baseband version it might work again.
This app would be awesome, anyone tried it on the photon yet?
Any News On This?
I tryied it - doens help me.... I created activity which is switch's baseband and turn it to USA gms baseband.... I lost connection :-((( and can't repair it :-((((
please help :-((( baseband switcher says "your baseband setting are incorrect. would you like to reset it to defaults?". I answer Yes and it reboots with old settings and don't work :-(
maybe somebody knows a way to reset baseband settings?

what sbf stands for? I just bought the phone and my reason to buy it was the sim card ability I would like to use it on my trips to Mexico and I would very much love to be able to nuy a sim card from a Mex. carrier and use that way.
I believe you can. I forget the post where somebody gave the name of the sim card they used...
You may need to contact Sprint to get international use activated, I believe at no charge.

I`m alone with this problem???
No mate, you are not alone, I just changed the stock rom for Sensation and I reckon I upgraded teh baseband as well to KH3 and now I am experimenting some trouble when connecting, before my network outside was faster and more reliable whenever I was but now I can hardly connec when outside and I certainly cannot connect only 2G, it only works if I have it in auto mode. The main problem is that I cannot remember what my former baseband was...
Sorry to bump but also have this issue. Vodafone uk with resurrection 1.3. Anything work best with ICS, vodafone uk? The current ones im trying are making it worse if anything.
First time asking for help but I can't find the answer to my problem. I have no service on my X10, no calls, text, data. No service at all, just grey bars with a BIG X. I don't know how to tell if it's a hardware or software issue. I don't think software is the problem. I put my phone in airplane mode one night and the next morning turned back to normal mode. I noticed later I had no service. I had been running the Wolf 4.0.0 for about a month when this happened, with no problems at all. I have flashed back to 2.1 and then 2.3, no change. Searched and entered APN's for ATT. I did find some posts about "CRASHING SYSTEM SERVER" but I don't think it applies to this software. Am I missing something? I sure don't want to pay Sony $185.00 just to re-flash my X10 with a quick fix.
Any Ideas???
My setup is:
Wolf_Xperia_4.0.0

Try your simcard in a different phone to make sure the sim is working as they can sometimes die I've had a few die on me over the years without even touching the sim since it was put in the phone.

I have same xperia x10i with baseband .71
it had same problem few months back and it was working fine
changing sim caused the problem again
now it wont get any signal with any working sim
Is that problem hardware related or software related
FYI i have tried stock 2.3.3 cm7mod and team rom 3.8/3.9 but no service...
Help plz
Regards,
I don't know what the problem was with my phone. It started working one day and has been fine ever since. I do know that I was using the phone in a weak signal area, 1-2 bars max, before it stopped working and when it started working again I was in a full bar area. A software glitch or antenna problem, not sure. I have 2 of these phones and side by side the network radios have completely different signal profiles. The phone I was having trouble with still gets half the signal the other one gets.
Thanks
Hello everyone, I am having a problem with my new Xperia P. I first got the phone on ICS. 54 FW and for some reason the option to select Network Mode (switch to GSM only, WCDMA only, etc.) was greyed out. I noticed that in an area with conflicting GSM/3G signal my phone lost signal for extended periods. I though by flashing a new ROM (Vision V4) that the issue would be solved. I flashed and am now able to access the Network Mode selection. It was on WCDMA preferred/GSM and I clicked GSM only, the phone immediately rejected this and went t\back to the state that it had been in. This is basically making my phones network features useless and I suspect the battery life is suffering as well. I flashed stock .75 ICS and even back to .54 ICS and the same issue occurs no matter what I flash. I went into the "hidden menu" accessed via button combination in the dialer and tried manually selecting GSM only from the list of preferred networks and the same issues occurs, no matter what option I choose, the phone immediately changes back to WCDMA preferred/GSM. This would not be as big an issue as it is if I lived somewhere else with better signal, but my home and work environment are both like this so it is a major issue.
I urgently need help in this matter, I have read about similar issues but either the thread has no replies or the suggestions do not work. I had read about some Sony forum members asking if I the persons had cut their micro SIM. I have, so I ordered a new micro SIM ready to be activated and it's on its way. These suggestions about the micro SIM were also answered with replies stating that they changed out the SIM and the error still occurs and I suppose it will more that likely persist in my situation.
If anyone could, I really need some help. Thank you for reading.

Hey mate,
Im not sure but I think you have a wrong baseband which might be causing the issue. (not sure cause i remember hearing somewhere that P covers all bandwidth etc )
If that might be the case, you need an FTF for your specific model to flash its baseband
Again, not sure so try this only if you dont get any replies soon

Yeah, I think it may be something with my baseband. Every now and then I get an "R" above the signal display meaning I am technically roaming but this is very random. I don't really see any flashable basebands for the Xperia P though. I will do more research though and thank you for the suggestion. :good:
Well, couldn't find anything so I just sent it back to the seller for a replacement. Mine had a bad pixel on the screen anyway. Here's to getting one that works in about 2 weeks..
I too have the same issue but my problem is that my device freezes the touchscreen on 2g network. On every Rom that I have tried.. I am still waiting for a fix..
Tried to change the SIM and network still the same..

Yes, that is very weird.. Are you still able to switch network modes? I'm on AT&T so the network compatibility should be fine, I'm just guessing we have defective units.. I emailed Sonymobile about the issues and got a response telling me that some carriers have a lock on their networks. This isn't true though because I have plenty of phones (Android and other) that had worked with 2G/3G with the option to select and it worked fine. I do this to all the Android phones I have ever owned. Hoping the JB update addresses the many issues we are all having with the many ICS iterations. I wanted to stop using Japanese smartphones (currently having to use F-10D until I get a good replacement) because of the hassle with use between countries and there being no development existent. I thought I could get a headache free experience from a less strict supplier but it seems I just can't have a good experience.
Like I said, I sent in for a replacement and should be getting one soonish, I don't know what I'll do if the same problem occurs except just wait for JB and see what it holds.
Can anyone with this phone on AT&T confirm that my phone was defective and not just (supposedly) carrier related?
I bought it from Saudi Arabia, only 3g works but freezes in 2g after some usage.. I am from India. I think unlocking SIM LOCK of my phone might fix the issue..
