No netwrok signal on hd2?

Hi, my Windows mobile HD2 all of the sudden is showing no signal. Could this be maybe a pin from the sim card reader or has someone seen something like that before??? I have an HD2 running android also and is working fine. So im thinking this could be a hardware program. I even downgraded the windows version to stock but it didnt work... Thanks!

1. Try another SIM card;
2. If dropped(or sit on it), it could be the 2 metallic pins(bent) from motherboard to GSM antenna(locate on external case);
3. Hardware problem(rarely, but possible).
Other than that, no more ideas...

ok before you go replace the SIM card, do this:
1. Sometimes turning the wireless connections off and then back on will resolve the issue.
2. Power phone down and back up
3. Make sure that Windows didn't decide to deactivate your phone's radios (aka airplane mode)
scroll to the end and hit wireless controls and make sure wireless connections and phone are set to on.

Try to install different version of Radio it might solve the problem.

[Q] Baseband Unknown, IMEI unknown

I brought a new Nexus 4 for only 3 days.
It dropped to the hard floor from about 80 cm high.
I did not check if it was ok after picking it up.
Next morning, i found:
1. Baseband Unknow, IMEI unknows
2. Wifi not work. The phone could find wifi access points, but after I entered the password, the SSID tured to "No in range".
After some hours, I found it had connected to wifi, and SIM card worked as well. Baseband and IMEI came back.
Then, after restarting the phone, baseband and imei lost again.
I read many posts about this. Some guys fixed it by set the phone back to factory roms (Including boot.img, radio and system...)
I tried, but not solved this problem.
I flash the radio to .54, .48, no help.
I installed rom from CM, no help.
I installed GetRil, it said the Ril file unknown, together with baseband unknown.
Any one could help?

Your antenna cable or something may have become loose after you dropped it. You can open up your nexus 4 with a few tools to inspect it.
Here's a detailed youtube video of a nexus 4 being taken apart and put back together:
-edit cant post links sorry. just search "Nexus 4 Teardown - Disassembly & Assembly" on youtube.

If the antenna became loose, the signal would become weak, even no signal. I do not think that this will lead to unknown baseband version, and unknown imei.

Exactly. It could be anything, but it seems like a hardware issue.

WiFi and Bluetooth Issues on SGH-1337M

Hi all,
I've been having kind of a strange issue with my Galaxy S4 SGH-1337M. I'll start off with a bit of background info. A few weeks ago my phone started having problems charging, so I replaced the charging port last week. Shortly after replacing the charging port, my S4 started having problems connecting to WiFi and Bluetooth. It's a little odd though. It still connects to WiFi networks occasionally, but when it does, its an extremely weak connection and drops almost immediately. It's the same story with the Bluetooth. It connects fine, but music playback stutters with speakers and my car's stereo. I've already taken it apart again to see if anything looks damaged or if the WiFi antenna was disconnected, but everything looked normal to me. My device is running Android version 5.0.1 and isn't rooted. I really don't know what's going on, and any help would be greatly appreciated.

Try a Wipe data : go in recovery mode and chose delet alla user data.
NB : All you're Data will be erased, need a backup if you wanna keep it.
Good Luck

Hello,
u can go heare ==> http://forum.xda-developers.com/showpost.php?p=50787570&postcount=2549 . See how to flash your modem, but first you need to know your modem's version ( ie : I337MVLUGOC4 or higher...) to do so, go to your dialer and type : *#1234# your modem version is called CP, google it, download it , flash it with odin, reboot and see if it's working.

If the wifi started after changing the charging port, it could be a loose connection somewhere or there is something wrong with the replacement charging cable.

That didn't work either. I also tried flashing the stock rom, which yielded no result.

I actually tried the old charging port to see if the issue was with the new component, but I still had the same problem with the old connector. I've checked all of the connections and everything, at least to my eyes, appears to be connected securely.

It's not uncommon for the wifi chip on the s4 to stop working. I have two motherboards sitting here that work perfectly except the wifi.

Okay, well I guess that's what happened then. Thanks for the suggestions everyone.

There may still be hope. Where did you get the replacement USB flex cable for the phone? I still say it could be the cable if the replacement was not oem.

I bought the USB port on eBay. The description claimed that it was OEM, but I don't think I would know otherwise. Like I said though, I have already eliminated the new flex cable as the culprit becasue when I reinstalled the old flex cable, the WiFi and Bluetooth were still broken.

The phone has the correct imei? If it does, then the wifi chip is probably defective.

May want to flash a m9 rom that's close to stock sense, I had to do that for mine to get GPS working.

calling out hardware guys to the rescue

Hello, im going straight to the point, i use my zenfone 5 (t00j) as a gps device all teh time, i ride a motorcycle all the time, unfortunally on a highway the phone flew out of the holder, got ran over a bunch of times by passing cars, but i noticed it was still alive, the volume buttons would make the bip sound when it reachs maximum volume ( screen wouldnt even light up so that was teh only indication). so i went on ebay and bought a bunch of parts. ok now the issue:
I cant get network signal, but i do have GPS and WIFI working flawlessly, what i wanna know is, does the wifi shares the same antenna? by that i mean that RF cable that connects the charging board to motherboard? is that the antenna for the network? it looks good dont show signs of damage but im at a lost, Sim2 was fisically disconected when i pick the phone up, and the SDcard was gone aswell, those were the main impact areas.
Can it be software bug or hardware? i've changed the sim card slots aswell and a factory reset
SMMI test shows only sim card slots fail and modem bus (wich i think its 3g?) wich would make sense not to work since cant get any signal, everything else pass's
Any help, any info on how that works? sim card slots send the info somewhere, where? what reads those signals?
thanks and if u know of somewhere more apropriate, i know this forum is more of a software related thing, but its active and i may get relevant info around here

respectufully, thats a whole bunch of nothing of an answer, ofc if i buy a new phone it will be solved lol, i have a new phone already, but i want to fix this one, hence my questions above, wanna try and solve it, since its only the network having issues, i might just use it as a dedicated gps/multimedia device since i fixed that much already.
the RF cable, thats the network antenna? what chip reads those signals?
