Very Unusual Problem 2G Networks Dead, 3G Fine

Well this is a new problem. My G1 seems to have decided it will not register on any 2G networks any more. Tried 3 SIM cards, all the same situation where 3G works fine then 2G fails completely.
I had been experiencing random cut outs on both the WiFi and mobile connections since upgrading to the latest Cyanogen firmware so upgraded to the latest radio. That worked fine for a couple of days but now no dice.
Also worth mentioning is that the device was crashing sometimes when the phone gets too much in the memory (for instance with a couple of widgets running it crashes when you start the camera).
Any advice would be great

Have gone all the way back to stock (and most things in between) in the hope than it was a bad flash but not looking that way
Also had the back off to see if there are any obvious problems (like a loose connection or obvious burnt board), but still no joy. Anyone know what sort of costs HTC would put in to get this sorted?

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.

Wifi, bluetooth. Sim and sd card problems.

Hello people,
Does anybody have problems with Wi-Fi( sometimes it works and sometimes it doesn't, and it shows a very poor signal and not all networks are visible), Bluetooth(won't work at all) and SD card mounting (keeps mounting and unmounting randomly)??
I'm using Samsung Galaxy S4(GT-I9505), CM13 (pretty much all nightlies I've used have the same problem), and switched back to TouchWiz, same problem. no fix.
If anyone knows or heard about these problems please tell me. And Thanks!

Yes I tried others, same problem. and no. SD card work fine, I dunno I think it has something to do with hardware, do you think so also?
I flashed back to TouchWiz, but Wi-Fi and Bluetooth still have problems, Bluetooth won't work at all, and Wi-Fi (doesn't work well, shows poor signal and not all available networks).
And SD and SIM cards are pretty moody, they keep mounting and unmounting randomly.

Hey! Did you ever find out what was wrong with this? Mine stopped detecting the SD card first and said it wasn't formatted right. Then went the wifi. Lastly, after a factory reset, it decided my SIM card wasn't there. It is. Everything was working beautifully for a few days with Legacy OS (I switched because I thought my Android update was why my wifi quit right after).
I tried the fix of putting pressure on the connector by putting a little piece of tape or folded paper over the connection point (just to the left of the flash- I'd post a link, but I'm not permitted yet- new user), but to no avail.

Problem with my nexus 6p

I think this problem surfaced ever since i downloaded the beta update for Android 7 on my Nexus 6P device. My signal coverage and internet speed ( LTE/4G/3G) started fluctuating on its own and now the condition is so bad that i haven't found any signal connectivity for the network that i use even though other users of the same network in my area are having connectivity. I tried to insert that sim on another device and it worked just fine. I have taken every measure possible, restarting, doing factory reset, downgrading to Android 6 etc etc, i just wanna confirm if there is something else i could do or giving it to the service centre is the only option left?
I cant even tell if the SIM card slot is broken because the notification bar does not show me the error that the SIM is missing or whatever, it is reading that there is a SIM card there, i'm just not getting the connectivity...
HELP ME! I LOVE MY PHONE WAAY TOO MUCH!! I DONT WANNA LOOSE IT FOR SUCH A LONG DURATION!

[H870] Can't turn on radio signal - no cell reception

Hi everyone, my H870 has seemingly given up on me out of the blue since about two days ago and refuses to connect to mobile networks, or even to search for them for that matter (trying to manually search for networks give back an error). I'm afraid the issue might be hardware-related which would be a shame as the phone is otherwise fine. I've tried changing ROMs (going from and old AEX AOSP to LineageOS, with full wipe) as well as kernels (Melina reborn for AOSP), to no avail.
Switching sim cards also didn't change anything, the sim is detected and it asks for PIN but then no network, which leads me to think it's a radio chip issue. Activating radio in the *#*#4636#*#* menu doesn't prompt the usual restart, and auto-untoggles if i go into another app then come back to it... IMEI is fine and not corrupted.
I'm really close to giving up on this phone and buying another one, but I thought maybe you guys would have another idea of something to try that could work before I do that. Couldn't find any similar threads on that matter but please point me in the right direction if this issue has popped up before !
Thank you in advance for your help.
EDIT : Flashed original firmware (H87030a_00_OPEN_EU_OP_0829.kdz), to no avail... I believe this is the end of the road for this phone and judging by the lack of answers you guys do as well haha

H873, should not have reset. Now i dont know too
