[Q] Frustrating rom problem HELP!!! - Captivate General

Almost every rom I flash ends up having the same problem: I randomly lose signal. Not the crossed out icon, but rather just no bars. This happens while sitting still and there does not seem to be any pattern to it. Some roms it would happen overnight, others it happens during the day. Some roms I can toggle airplane mode on and off to fix it, while others I need to reboot. I always end up back on stock roms because the issue renders all custom roms unusable. Does anyone know what I can do?

Have you tried going stock and see if the issue arise?
Did you try to go 2G only and see if your signal holds?
It could be a bad 3G signal and your phone is dropping in/out to boost your signal. you could be between two towers and your phone jumps from one to another because of low signal. Could be a bad antenna if the problem persist under stock and 2G only. There are alot of things that can cause this issue and the phone itself can be the source. You have to factor out every possibility to narrow it down.

I'm switching to 2g only and we'll see if it holds. I'll know in a few hours.
I would be surprised if it has to do with towers, it isn't something that happens exclusively in low signal areas.
At work I have full HSUPA+ signal and it still happens, at home I barely get 3g signal and it happens there.
It happens at my girlfriend's house too and there is moderate to high HSUPA+ signal.
The problem DOES NOT persist with stock roms.
DOES NOT lose signal when data is disabled
******************UPDATE***************
even when locked to 2g only, it still loses signal.

Seems to be a hardware issue. I had the same problem on my last phone (a LG-VU) and I red-necked it and stuck a small piece of wire in the phone's antenna. It worked surprisingly and I had no problems with it for the remainer of my contract. But before going to those extremes, I would flash back to stock gingerbread, and try several different ROMs and Modems.

HAve you tried falshing different modems???????

You might have a bad sim card. My phone was doing that last summer, and then one day I couldn't get a signal at all. Rebooting would fix it but only momentarily. I hit up an AT&T store on my lunch the next day and got my sim card swapped and lo and behold, no more problems. LOL I remember I was trying to hide my Cognition boot screen from the tech as my phone was still under warrenty at the time.

[Q] Very bad signal on Sensation xe

Hi. i have a sensation Xe. I installed ARHD ROM a month ago and it was my first ics ROM. after flashing i had the WiFi issue. it wouldn't connect when i wasn't in airplane mode. but i used wifix and both WiFi and data signal was good. but it bothered me and i thought it might be a radio issue, so i tried flashing a new radio/ril. i tried different radios and they didn't fix the WiFi issue and also made my data signal so weak. i restored my original radio/ril but i still get weak signal. it always have 3 lines out of 5 and sometimes it dissapears completely with a cross icon on top of it even when i don't cover it's back with my hand. i tried to raise the 2 metal parts below the battery to make better contact with cover but still no luck . Any suggestions?

I wonder why are you facing such a problem. Well you can try this app known as Network Speed HERE .
It helped me boosting my signal too

Not sure what to do?

Was having random signal drops and what seemed to be battery issues. Called T-Mobile for a replacement, but it seems all the issues disappeared. Should I swap it anyway or keep the original with the low h boot?
Mine was doing the same. Then i found out it keep going to Airplane mode turning off. So i had to restart or turn on and off airplane mode. Once i changed the rom on my phone it stopped.

If you know what made the issues go away, just keep the one you have.
I can't comment on your battery issues, but for me the cell signal is way more stable since radio 1.06s. Still not very strong, but not as jumpy as it was before.
If it's really a mystery, and you think your issues might suddenly come back, get the replacement, altho that's no guarantee either. Do you know which HBOOT a new one would come with?
-Jobo
Well boot is 1.09 on the one I'm using. Not sure what the replacement is yet because I don't have it in my hands yet. I'm running the EU radio and signal stopped dropping and battery got better. There are way to many factors that could have solved it

[Q] Broken modem after root/ROM?

At least that's what I think it was... I rooted, unlocked BL, and flashed a couple custom ROMs and radios on my VZW GS3. I tried JellyWiz, AOKP, ParanoidAndroid. I can't be sure exactly when, but at some point, I lost the ability to get a good signal.
I work in a basement where only Verizon gets service. I used to get 5 bars all the time here and was able to get 1X network coverage and stable WiFi. After rooting, ROMing, whatever, I couldn't get any signal at work (the big circle-slash symbol), was dropping WiFi like crazy, and at my house which is a good 4G area, I could barely get 3G and making a call was a hopeless endeavor. I would constantly drop calls, and the ones I didn't drop were so choppy that the person on the other end of the phone was completely unintelligible.
It should be noted that with each new ROM I flashed was a clean flash. I Odin'd back to stock everything to try to remedy the issue. Bootloader got relocked, baseband reset to stock, everything. I put this phone back to exactly how it was out of the box. The problem persisted.
I finally got a replacement phone and the problem is gone. Besides the fact that my VZW-using colleagues had signal the whole time, this new phone also gets signal.
Now I'm hesitant to tinker with this thing because I'd rather be on stock TW than have a phone that is non-functional at the two places I frequent most - work and home.
Does anyone have an idea what happened here???

Intermittent data and signal drops

I'm experiencing an unusual issue where my phone will have full bars and not have data, or some times just drop all bars and data for several minutes. Some times a reboot fixes it but not always; the data comes and goes as it pleases. The issue seems to be more persistent with data drops than signal. The areas in which I'm losing data connection I've always had a strong connection in the past.
My first thoughts was a software issue but now I'm not so sure. I'll explain what I've tried and hopefully someone has some ideas.
a) Clean install of Cyanogenmod 10.2, and 10.1. In the past I had no signal issues with either.
b) Flashed the latest radio i727UCMC1 (was already flashed but did it again to be sure).
c) Checked APN settings. The settings seemed fine but since the issue is intermittent I don't think this is the problem.
d) Scanned for available networks and tried several of them. This resulted in no service on all but one, which was the default.
I'm working on getting back to stock right now but I was hoping for some insight while I do so.
Thanks.
if it still happens on stock and you tried it a different location then some hw prob like the antenna connection or the modem chip is dying, search this forum for "antenna" as it could be helpful

Interesting, and yes it's still occurring on stock. I heard that AT&T is having issues but it's been a couple days now. If it is hardware I'd be surprised as the phone hasn't faced any devastating drops lately.

The wifi is turning off randomly as well. It isn't dropping signal, it's literally becoming disabled and then re-enabled again. Sounds like my radios are tweaked or the antenna is shot. Already tried flashing the radio though. I'm not sure how helpful trying to boost the signal will be given that wifi is dropping too.
i had the same problem after a emmc change, wound up changing the motherboard, not what u wanted to hear !!! sorry fixed it though.

Cellular/call signal drops off when wifi is on

I just started playing with my wife's new idol 3 phone. everything is great so far with the exception of when wifi is turned on I noticed that cellular signal turns off and on sporadically. When wifi is off, the cellular signal never drops.
Updated!!!!!! ALCATEL THANKS!!!
The WiFi and Cellular signal issue is gone!! New update is great.
I have not noticed that. I leave my Wi-Fi on and connects when home without issue. I've check cell signal levels regularly on new phones. My first impression with this phone is that the cell reception is excellent.

I've noticed that a couple times as well. I assumed it was my SIM card as I changed carriers the same time I got this phone. It's not a deal breaker for me as I actually don't use the phone for calls much anyway. But yeah, it needs to be fixed. Just waiting for the next update.
Great, i thought maybe it was her phone in particular. I mean, I accepted the current update thinking that would solve the issue, but it didn't. Same story.....when wifi is on, the cellular signal turns off, on, off, on....maybe within 5 second intervals. Im shocked many people haven't complained about this.
if it wasn't for your response I was going to return the phone back to Amazon and exchange it for another one.
other than that I think the phone is excellent for the money and since my wife really isn't into development and rooting, for her this is the perfect replacement for her defective S4. however I would still like to be able to install a custom recovery at least.
My issue isn't anywhere near as bad as yours I would say. If yours is turning on and off a lot them you may want to replace it. I notice mine turns off once a day for a few seconds but I'm sure it does it more and I just don't see it.

I've used my phone to tether a few times and noticed the cell signal drops now and again....there is an app but I can't remember the name..something like "connection stabalizer" that toggles airplane mode on and off when it detects a dead connection....it might do the trick.
I have never experienced any of my previous phones do that, so i will most likely be sending it back for an exchange from Amazon.

I have never experienced this either. Have you tried a factory reset yet? I may try that in a couple of days and see what that does for me.
Well see, before i took the latest update the problem existed.........then, after the latest update the issue still exists. So i don't think a factory reset will do it but i will before i actually mail it out.
I reset the phopne and installed a mobile network detect app that notifies me when the signal drops. we'll see what happens.
I have no job so I have the time to blow
I am having the same problem. I am losing the signal repeatedly. It goes to no service then comes on to two or three bars even when I am in the exact same location.
So far so good. 6 hours later and no signal loss yet. On another note, the reset fixed an issue I forgot to mention. when downloading from the play store the download would start and immediately get stuck at 66kb. I would have to start and stop the download two to five times before the app actually downloaded. I just finished installing all my apps without an issue.

Borghi, so your WiFi is on when this occurs too huh?
I will lose signal when on WiFi with LTE enabled. Switch to WCDMA/GSM and it doesn't happen. Weird. Going to factory reset this weekend when my new SD card comes.

Wow so maybe this is a 100% Idol 3 manufacturing issue that demands for a recall.
Me returning the phone for another one is futile. I mean who doesn't want to keep their phone on LTE???
It might also just be a firmware issue.

True.....
It's been 28 hours and as care as I know I still have not have a dropped cell signal after the factory reset. If you have an issue will the cell radio try a factory reset first before returning it.

With the phone connected to Wi-Fi?

Mostly. Wi-Fi was off about 6 hours while I was sleeping. I'm using Network Signal Info Pro to tell me when I lose signal. I know it works cuz I turn on airplane mode and it notified me. I carry the phone around the house so I don't miss a notification. So far in 33 hours still no signal loss.
