No signal for 1-2 secs - T-Mobile LG G2x

Hi everyone! So I got G2X last week and the first day it worked great. It shipped with 2.3.3 on the device. Ended up rooting it and flashing a custom 2.3.3 rom, followed by Cyanogen mod nightly 2.3.5. Now, next day was my first day back at work and for some weird reason my signal would drop completely for 1-2 secs followed by device re-acquiring it and everything is fine again... super annoying and results in crappy data . Basically 4G/3G completely turns off, same goes for the radio, then its back to normal, anywhere from 2-4 bars usually. Any ideas?

That happened to me on CM7 aswell. I'm not exactly sure what causes it, but I haven't had any problems on the stock ROM.

I usually just have gps locking issues

We had a new Guy start today and he's gone the same phone on 2.2 though, doesn't seem as if he has same issues.
Are you just running stock rooted rom now?

Random reboots?

First off I want to start by saying I have flashed my rom to Bamf 1.5 remix. I do not overclock my phone however I have tried limiting my clockspeed hoping to prevent a reboot. The phone did not start the random reboot until I flashed to said rom. I have tried reflashing but no improvements, any ideas?

It has happened to me but I believe it just me OCing, flashing back to the kernel that I was using before when my phone was stable and testing it out. If not, I will just go back to 1.5
Also, does anyone know how to edit the power control widgets in the pulldown? I can't find any options. Thanks.
Did you flash the new radio when you loaded up BAMF 1.5?
If so, there's your problem
Happened to me with BAMF 1.6 and leankernel 192X, but only when I set it to ondemandX thru SETCPU. Other than that I've had no reboots.

yeah its pretty common for people who flashed the new radio to have reboots. i have had some of those issues, i found that using different kernels at different clocking speeds made my phone more stable. NOTE: i am not a pro, just something i noticed.
What's really behind all the random reboots?
OK... So I've tried just about every rom on the dev thread, I purchased the TB on launch date and had it rooted as soon as Jcase posted S-off instructions... I am now on the new radio and until today, I haven't had a single random reboot. Then all of a sudden, just about an hour ago, as I'm backing out of Tapatalk, bam... Phone rebooted itself...
Now I've been reading on just about every rom thread where people have been experiencing random reboots. Some think the new radio is the cause, but some people are on the new radio and have not experienced this. Others on the old radio still get random reboots.
Others think its the rom but people have noted this issue on most If not all of the rom threads.
Others think its the kernel that's causing it, but again, there doesn't seem to be any pattern to nail it down to a single kernel. Furthermore, some of these people are not OCing, myself included.
Which leads me to the strangest part of all this. My wife also has the TB. Her phone is totally stock and is not rooted. I got it for her day after launch and for the last few weeks, her phone has also been randomly rebooting. Not constantly, mind you. Just enough to be a nuisance. She has still not updated to OTA... The only suspect to this is that this appears to have started after the 4G outage a few weeks ago... And we are in a 3G only area but there was a day or so we could only connect to 1x...
So what's really causing these random reboots? I'm no expert, never claimed to be one, but is it possible that something going on between our phones and the Verizon network is causing this?
Thoughts... Ideas...?

I have had a few reboots across a few different rom, radio, and kernal combos. The only thing that all my reboots have had in common was I had GPS enabled. Ive yet to see a reboot with it off. Could just be a coincidence.

stock rom, not rooted, has had multiple random reboots
I have had no random reboots, or none that I have personally experienced. I figured if my phone was randomly rebooting I would have noticed a considerable battery drain. I have not noticed that yet. I honestly think that this might be an issue for people with little to no 4g coverage. I am bothered that this has not been addressed yet by verizon as I have seen so many people complain about this.
Hopefully I dont get these either, who knows may it is just phones that are may be defective hardware wise.
Well i just wanted to drop my $.02
I am Rooted and have been just about the same time the OP has been rooted.
I USED to have reboots. I install the full RUU and had reboots i also installed just the RADIO file and had reboots. I also reverted back to stock by the RUU provided by JCase. I Then flashed 1.6 followed 1.6.3 and have not had any problems. I assume that those 2 already had the radio file in them and i didn't not have to flash anything additional. Since being on 1.6 then 1.6.3 i have experienced not 1 reboot. Unless i did it myself.
I did notice then before when i did have the reboots (when i manually flashed RUU or just the RADIO file). I had reboots 3 different ways. I would either get a reboot when my phone had been sitting next to me for a while i would notice the white screen and know it was a reboot. Also the 2 other times was backing out of TapaTalk or native browser/dolphin HD.
So i don't know if that is in a way related. I just don't have them anymore.
I noticed that whenever my phone would reboot (on the leaked radio only,) I had a weak 3g signal. I watched this happen several times. My guess would be the people who aren't having reboots are in an area where they constantly have a good signal. Can anyone else corroborate this?

This is a possibility... But if that's the case this will be the first Android device I've owned that has rebooted itself randomly due to GPS. Even the Samsung Vibrant, which had horrible GPS right out of the box, didn't reboot itself when it was turned on...
However, if this is the case, why has this only become a recent issue.. now my memory isn't so good... But I don't remember seeing much about this issue on rom threads until recently... I.e the past few weeks... Neither my wife's nor my phone randomly rebooted until just a few weeks ago, and we both have our GPS turned on everyday, all day...

I live in a strong 3G area and my phone has never re-booted itself as far as I know. I'm doing the update tomorrow and will be interested to see if the problem starts.....I hope not.

Unfortunately, I had a solid signal when my phone rebooted this afternoon. I was a stone's throw from Philadelphia on I-95. I've never had signal issues along I-95 between New York and Philadelphia. I'm running the released update.

This as well is a possibility... Although I am in an area where 3g is strong... I have seen on my and my wife's phone... Even when standing still... That the 3g icon will vanish and come back seconds later...I am in a decent sized college town, population of about 70000... I couldn't say how strong 3g actually is but its everywhere in the city limits... And most of the countryside...
I have traveled to cities with strong 4g but I didnt stand around long enough in a single place to really watch the phone to see if it was dropping data...
Thanks for the constructive input, everyone... Lets keep the corroboration going and see if we can find a pattern..

The only time I had reboot was on the leaked ruu which is now the OTA.
Once I went to BAMF 1.5 with new radio and new base no reboot. About a week ago I flashed back to stock radio just to compare after being on the new one for a while. I see nothing different between them really.

Still suffering from random freezes while in standby.. Anyone else?

I updated my phone (flashed stock 2.2 rom, flashed stock recovery, then used LG updater tool, then ran recovery after flashing) to 2.3 on the day v21e was released and from the day after flashing I am still having to do battery pulls as the phone locks while in standby. Am I the only one having this issue or are there others as well? hopefully the official release doesn't have this problem.

I've had lockups since day 1... It's gets me so mad. I have a replacement coming in a few days. I've tried everything... Rooting, unrooting, and the 2.3.3 update didn't fix anything! But one thing which was weird, is that 2 days ago, when I was at Oceanport, NJ Warped Tour, my phone was in my bag. It was about 98 degrees outside, and my phone was really hot... It managed to stay on the entire time... WHICH WAS WEIRD! But I hope my replacement doesn't have an problems.
My dad has a G2X with NO PROBLEM AT ALL. Absolutely NO screenbleeding whatsoever! and he's NEVER had a lockup/reboot!
7/29 EDIT: I received my replacement G2X in the mail yesterday, and it appears that all of my issues are gone!
I think I'm going to wait until the upgraded ones come out and try to do a return for the newest ones.
I am having the same problem. I got a new g2x about 2 months ago. it was perfect. lost it. got a replacement and have had the same issue you are having. after update i still have the same issue. i just leave it on the charger. i set it to not sleep while charging and it will not shut down. as soon as it is unplugged it will shut down.
I had to wipe my phone and factory reset to make run as it should after to the update

I did that as well, twice actually, but that didn't fix the issue.
I'm trying an experiment by uninstalling setcpu and juicedefender and just letting the kernel manage my cpu. I expect less overall battery life, but I'm hoping that by eliminating the screen-off profile and constant radio on/off, maybe...just MAYBE it might help with my sleep of death, freezes, and random reboots.
I have sinced changed where screen wont timeout for thirty minutes I did two factory resets since update and still does not work time to return or change the rom.

I had very few random reboot issues before the GB update. Maybe 4 or 5 in the months that I've owned the G2x.
Since the GB update I've had several each day. I've hopped around onto various ROMs to see if one would correct the issue and to date, none have. I'm considering restoring my Froyo nandroid to see if that gets my stability back.
Tmo is sending new replacement. Finally got tired of attempts to fix.

You had a defective unit, software wouldn't fix it. If it was a "kernel" issue. One of the custom kernels on XDA should've fixed it.
My g2x froze all the time while idle. I read a thread once that claimed upping the minimum CPU clockspeed to 312MHz fixed the problem, so I used SetCPU to increase it and it stopped freezing after that. Reboots were another issue though...

[Q] How are your reboot issues?

I didn't have any when I first got my phone, right at release. About 2 weeks in I started to get the freezing/reboot issue occasionally. It went away for a time when I started modding my phone with ROMs. I'm currently running Weapon G2X, and for a time had no reboot issues. Now, about 3-4 weeks into using that rom, they are becoming a problem. My G2X now seems to reboot once every couple of days or so, normally when I'm using the phone. I'll be in messaging, hit back, then it locks up and reboots on me.
How are your issues? Still having them or no? I plan to update Weapon sometime in the next couple of weeks, or perhaps give CM7 a go.
Just got mine from CL last week. Have yet to experience a reboot or freeze. Maybe it's just a few batches of G2x's that experience that.
mine hardly ever freezes up to be honest. I am using xboarders tweakd GB rom. But then again, I've never really had an issue where it just reboots itself even before rooting. my phone does sometimes run really slow though.

Really? Slow-ness should definitely not be an issue with this phone. Have you tried Weapon or Cm7?
I've only had one reboot and I had this phone for 5 months. I got a reboot when I was showing my friend. How fast and cool my new phone was. He asked to see it then he pulled down the notification bar and it just rebooted. Other then that one time, never happens.

One freeze and one reboot on a stock rom in a month.

What reboot issues?
Never had it happen after 5 months of owning the phone.
Stock, rooted, Go launcher ex, SetCPU -> almost no reboots.
Before those steps, quite a few reboots per week.

I've been trough various roms and had the stock froyo in the beginning for quite some time - never had a reboot or a freeze. Only once, I remember, it would not recognize the headphones that I was plugging in and I had to reboot.
I've only had my phone reboot once when messing with SetCPU. Other than that, no reboots. I got my G2x within a week of it coming out and have never exchanged it.
i'm using pure stock so i'm not sure if you want my opinion but i've had the phone for a month now. it was perfect in the beginning with zero issues but up until last week it's been freezing constantly and rebooting. i've had to do three battery pulls and it's rebooted on me three times. and i thought i got lucky with a "perfect" phone i really want to try exchanging it but i'm afraid to get an even worse one and i am not paying 20 bucks to get a refurbished phone that's insane
U should flash newest weapon room, this is great room and will fix reboot bug
I used to get freezing and rebooting all the time several times a day on stock froyo but ever since I started going on nightlies since around #60 I think it was, I rarely have reboots... my wife got the phone on the same exact day and she's still on stock rom with no issues
Running stock since I got it a month ago. No reboot issues. The only freezing issues I have is when I try to use ANY screen capture app. I managed to get one of them to work...once. After that, back to freezing. So as long as I don't use any screen capture apps, I have a smooth working G2x, lol.
I got 2 g2xs. One of them got reboot issues. Called T-Mobile and got replacement and no more complaints. All is good now. Last fewweeks I got flashaholic buy. Flashing different rom every 2days.
Stock Froyo rooted. Used to get SOD freeze and reboots every week. Started daily shutdown/restarts a few months ago - never had either problem since.

Constant Data loss

Hi, i hope someone can help me but im running a Mytouch 4G slide with Cyanogen Alpha 5 with s-on and everything works great and has been for the past 2 days since purchased and rooted it, Today however i have been having constant data loss. What happens is on my signal bar i can see the H come and go come and go come and go for about 5-10 seconds intervals, when it comes, it immediately goes away and then comes back after about 5-10 seconds. I tried to do a factory reset and after losing everything i hoped it would fix it but it only fixed it for about 5 minutes then it continued doing the same exact thing as before but i have great signal reception. If anyone has any clue on how to fix this or maybe get a new Radio that fixes it, i would be more than glad to turn S-OFF as it is currently S-on. Thank you and i really appreciate all the hard work and help!

I'm having the exact same problem and have been running CM9, Alpha 5, S-ON since a few days after it was released with no problems at all. I didn't notice it until I got to work since I have wireless at home but have not had data all day. I called T-Mobile and they're not experiencing any outages in my area (Philadelphia) so that's out of the question. The only changes that have been made to this phone have been making sure to keep my apps updated.
I know this isn't an answer to your problem but you're not the only one having it. Hopefully, someone can provide some insight.

Note that I've had the same data issues on CM9 Alpha5 with two different devices. I was able to replicate the intermittent data issue on my sister's mt4gs. Her's was s-on. Then I s-off'd her phone using revolutionary and still had the data issues.
I reflashed back to stock 1.63 and data worked fine. Then I used JuopunutBear to s-off and flashed CM9 Alpha5. Data has been consistent and flawless on both devices ever since.

Changing the APN setting to internet2.voicestream.com worked for me but I'm still curious as to why after a month of running CM9 A5 with no problems, the data just dropped on me today.
I think this is nation wide and not just a rom problem a couple people I've talked to have been having data/signal problems all different phones.

Not necessarily, i think its just the Mytouch 4G slide running the cyanogen.. Im running an HTC Amaze with revolution ICS 3.6 sense s-on for over a month now and it has worked great no problems whatsoever... as for this Mytouch 4G slide, i still cannot get this problem fixed, they phone gets data back at times and then the problem hits it back just a couple hours later and it is very frustrating. I have also tried to fix it by doing the whole root process again and that only fixed it for 24 hours till the next day so thats out of the question as to answer post #2. I guess i will just have to wait and see for a new cyanogen update to come out for the Mytouch 4G slide.

[Q] Skyrocket freeze/shutdown on signal loss

Hi. Let's get right to it, shall we?
I was running a 4.3 Rom on my phone. Worked great while I was at my house though I did notice my signal seemed lower than before I installed it. But I didn't worry about it too much. Ran the Rom all weekend without any issues. Coverage in my city is pretty good, so I never had a signal drop.
I work in a pretty rural area of PA which causes me to lose my signal a couple of times while commuting there. So, on Monday when I got to work, I had a blank screen and all buttons were unresponsive. I did a hard reboot which went fine until the phone tried to reconnect to the network. Then it went back to the blank screen and forced another hard reboot.
Thinking this was an issue of cm10.2, I went home and reloaded a 4.2 Rom. Again, it worked great until the next day when I returned to work. Then the shutdown/freeze issue arose again. So I went to stock 4.1.2 with stock kernel and radio. No extra apps, nothing. The only thing custom on my phone was the recovery. Anyway, I still had the same problem.
As long as I don't lose my signal, my phone works awesome. And it's not the loss of signal that's bad, it's when the phone reaquires the signal that it breaks. I went to AT&T and discussed with a rep but I seemed to know more about phones than he did ( his words, not mine ) and I couldn't reproduce the problem because, of coarse, there was a perfect signal at the store.
So, I'm asking for thoughts, ideas, and suggestions on how I might fix this problem or what might be wrong. I respect and appreciate, any help I might get from this fine community. Thank you all in advance.
So when you say after you went to stock the only thing custom was a custom recovery ...
Odin a ucmc1 stock the one which also takes you to stock recovery and do your wipes from there.
See if this resolves the issue

How does the recovery effect the phone when it's on normal and not in recovery mode? Please ( and this isn't sarcasm ) Talk to me like I'm four years old.
Mine did something like that also, I was on CM10.2 20130920 Nightly clean install with TWRP 2.6.3.0 and everything was fine then phone froze and started vibrating, camera flashed, power button wouldnt do anything I pulled battery and reinserted it and same thing just vibrated. Finally was able to go to DL and reinstalled stock booted just fine I set up the phone and couple hours latter same thing phone locked up started vibrating and nothing.
I know it is recommended to use CWM 6.0.3.7 but figured the lates TWRP would work. Now I have a worthless Skyrocket that all it does is vibrate, I can take the battery out and use it as paper weight.
