Cingular Radio Question - Cannot Receive Calls

[Superman859]

I have the Cingular 8125 version of this phone and over the past few weeks I've had one nagging issue with the phone. I cannot always receive calls (The 'E' symbol to the left of the bars turns into an X sometimes, or sometimes it even boots with an X there. I can make calls but not receive them when this is the case)

I'm not sure what it could be. I went back to the factory ROM from HTC, and it seems to work better than a couple other ROMs, although it just acted up again (after about a week of behaving nicely). If I clear storage and make it fresh again, then it seems to start working again (like now, although I'm not sure how long it will last this time).

So, could it be the radio? I have no idea what the radio actually does, but it sounds like it involves calling. When I first wanted to install new ROMs, I tried to do a HardSPL change or something following a guide here. Eventually I went back to original data, radio, etc. and now for new roms I do SoftSPL. Here is my device information - please let me know if something doesn't look right...

ROM version 2.25.11.1 WWE
ROM date: 5/11/06
Radio version 02.25.11
Protocol version: 4.1.13.12
ExtROM version 2.25.11.102

WM5.0 OS 5.1.195 (build 14928.2.2.0)

IPL 2.25.0001
SPL 2.25.0001
GSM 2.25.11
OS 2.25.11.1

If all of this looks like it should from the factory, are there any other ideas on what causes this issue? Again, I can ALWAYS make calls, but if it acts up and that 'X' shows up where an 'E' (or 'G' occasionally), then received calls go straight to my voice mail.

Note: I bought the phone on eBay and it is supposed to be unlocked for any service provider. I have AT&T so I do not know if it truly is unlocked (and don't really care, for now). However, I thought I would mention this in case that process might affect the information above, or if in the process it could cause a problem such as mine with the phone. I have flashed new ROMs and things of that nature several times, which may or may not set the phone back to default (locked to AT&T) - I do not know these things.

I had the same problems that you are experienceing....so I upgraded my radio to 2.71.1, and it pretty much fixed all of my problems...simply hit up Google for Wizard Radio 2.27.1 and you should be able to find it.

[Superman859]

Just for verification (as neither are bringing results that jump out at me), which radio am I looking for? 2.27.1 or 2.71.1 ? Your answer consists of both. I am assuming 2.71. I found 2.71.11 and downloaded it, is this correct?

Next, should this not work I can easily revert back to the default radio, correct? I'm pretty sure, but just want to make sure as I haven't specifically updated the radio - just ROMs (which I believe have various radio versions anyways)

[ashasaur]

yeah man, 2.71.11 is correct, I kinda got cross eyed for a sec there lol. But yes, 2.71.11 is the one that I have been using for a good while now, and I have had no problems with it. And also, yes, you can revert back to your old Radio ROM if this one does not work any better.

Thanks. I'm about to update and we will see what happens. I will post results for anyone curious that runs across this thread.

I've had the issue on the factory ROM, jaguar 4.0, and another HTC-business or something ROM, so perhaps this radio update will fix it.

2.71.11 radio installed. When it reset after flashing the ROM, the phone was not working properly (same issue, not receiving calls). I did a soft reset and it is working now, although there hasn't been enough time to see if it will continue working.

However, I would like to note that I am pretty sure of one thing now: When the phone boots up, sometimes the GSM row is missing (only shows the other 3, not all 4). When this happens, the phone cannot receive incoming calls (but can make them). When all four show on boot, the phone works fine. However, it may be that while the phone is on, it becomes disconnected somehow and stops working. I haven't determined that yet, as this is just one thing I am starting to watch patterns in.

There are quite a few other reasons other then Rom(OS) or Radio Rom in not getting good reception or signal quality,it may cud be a Hardware problem,the external antenna might not be getting a proper connection with the internal antenna connectors,did you ever drop your phone,it sometimes happen that while dropping the connectors loose proper connection,secondly,may be the network signal quality is not better in the area where you move,try out in different locations,check if it improves.
BTW,OS (Rom) has got nothing to do with reception/signal quality,its only the Radio Rom (GSM),which improves the signal quality.Changing/flashing Roms (OS) will not effect Radio(GSM) of the phone,it'll only effect if the Rom which you are flashing contains an upgraded version of Radio Rom in it.

Thanks for the response. I knew only some ROMs included an update for the radio. I've managed to get Jaguar 4.0 installed back on the phone and the 2.71.11 radio. It's been working, but then again that was only since last night. We will see if it lasts through the week.

If not, I will attempt to check out the hardware connections for the antenna. I took the phone apart once when I was letting it dry out after an accident, and it isn't too difficult to take apart. Just need to look up where the antenna connection is. I haven't had any major drops, but the phone was purchased used (although it worked perfectly fine for a couple weeks I believe when first purchased as I was testing out various ROMs for it). Anyways, thanks. I will check antenna if this radio update doesn't help.

It still sounds strange though. The signal bars would say the signal was strong, I'd have great reception making calls, but the 'X' would be to the left of those signal bars and I couldn't receive calls at all. It seems that if the radio / antenna was causing a poor reception, it would apply to both incoming and outgoing calls and the reception would correctly be represented by the signal bars. Again, the signal bars are usually strong, even when I cannot receive calls.

Something is screwy, i had TNTv2 6.1 flashed for a couple of weeks with the 2.19.11 radio, seemed to work fine. Just recently its been acting up. Last night even, people were trying to call but my phone never rang, no SMS, pages, or voicemail notifications would go through either. I did notice that my phone dropped signal and displayed an H (prob similar to your X) and then got signal again. After it registered again, still nothing.

This morning i did a soft reset, SMS notifications didn't come through until i sent myself an SMS through email, then they all flooded in....

This whole radio ordeal sucks. I'm on AT&T btw.
