[Q] Evo randomly reboots to white screen and vibrates 5 times?

Can anybody help me out with this? I've already searched but haven't found a clear cut answer on what to do.
For a while, I've had random events that cause my HTC Evo (running the latest stable release of CM7) cause my phone to suddenly show the "HTC Evo 4G" white screen, then go black and vibrate 5 times while having the green LED on, which never lets me do anything until I pull the battery out and start it up again. It used to only happen when I did specific things, like whenever I tried using Google Goggles at the store (and had to go through all the trouble of disassembling my 3 layer protective case just to pull the battery again). It even happened again yesterday when I was trying to use Goggles on a specific item, but it has happened before in other events since then, like when I was browsing my phone's running applications menu, or even one time when I was simply browsing the internet on it.
I've been taking steps to try and fix it, but I think it's been getting worse. I tried downloading CM7 and Google Apps again to flash on the phone to see if it fixed anything. I tried doing this again, but clearing the data and cache this time. I tried flashing the latest CM Recovery (since I stayed with 2.5.x.x for as long as I could remember), and I'm pretty sure it's gotten worse. There's points where I get to the CM7 boot animation and the phone then does the white screen and five vibrates again, and just a moment ago when I was sure I finally solved it after clearing data and cache, while filling out my Google account info, it happened again and I was greeted once again by that horrendous white screen and the five vibrates.
Now I don't know what to do. I still have S-OFF, but I have no plans to unroot. Can anybody think of suggestions? I've already tried Googling and haven't gotten anything useful enough to help me so far.
EDIT: I guessed it would help if I was a bit more specific. This started happening about two or three weeks ago after I tried using Goggles for the first time in ages. Since then, I've had this issue coming back over and over. It also puzzles me how Goggles usually works completely fine when I'm at home but causes the phone to go black and vibrates 5 times whenever I'm at a store.
Also, right now, I re-downloaded CM7 and Gapps from the CM mirrors instead of simply reusing the ones that ClockworkMod had saved for me already. I hope this somehow makes a difference.
Also, last edit, if I manage to solve this somehow, I'm going to definitely post the answer to what I did in case anybody else out there is having the same issue.
EDIT 2: Welp, re-downloading CM7 and flashing again didn't do anything to fix the problem. I'm going to try another ROM to see if the problem persists. I really want to stay with CM7, though.

Did you wipe everything? Cache and so on ect....?

I wiped everything and I'm still having the issue.
I also caved and I'm going to unroot because the retards over at the Sprint repair center refuse to look at it otherwise. I got my hopes up after hearing on places like XDA or the CM forums about how Sprint didn't care about rooted phones, but I guess the Sprint guys in my area do. I'm currently downloading unrevoked forever son and PC36IMG right now.
I'm just hoping I can get a new Evo after this, because there's a chance I could lose root forever after doing this. But I'm so certain it's a hardware problem.

Why would you lose root "for ever"?
Just curious ....

I had the same exact issue with my Evo over the past 2 weeks. But I never use Goggles and run MIUI pretty much exclusively. I was never able to fix it and it just got worse. I unrooted and still have the same problems.
I notice it happens on 3g data, I can't remember when it happened on wifi.
I am selling mine back to Sprint tmrw and using my upgrade to get the Nexus S for$50. Then hoping the Evo 3D comes out within 30 days.

I took it back to Sprint today, and after being treated like a second class citizen for rooting over and over, they managed to somehow fix the random reboots, but have initiated the OTA update for me. Now I'm sitting here with it and it's asking if I should install it now or later.
I'm hesitant because I tried to unroot earlier, and since then, the technician at Sprint said that it wasn't really unrooted or something (I remembered using unrevoked forever last year when I rooted). I'm scared that maybe I'll lose my chance at being able to root again if I accept the update or not. I'm also scared if I won't be able to get full root from here.
EDIT: SON OF A *****. I can't believe this. I applied the OTA update like a good boy and everything, and then the phone starts boot looping randomly again. This is the last straw. I'm going to go back to Sprint tomorrow and be more in-your-face about this problem. I'm through letting them treat me like **** just because I rooted my phone once.

I have a similar problem.....
My problem is random. My phone will go into constant reboot mode until I pull the battery out for 10 minutes. Just pulling the battery and putting it back does not help.
I also noticed that I am losing GPS signal occasionally. It is random too. The GPS will come on and work for about 5 minutes then just lock up. I have to reboot to get it working again and there is no rhyme or reason as to when it will stick (or wont) or how long it will last. It may work for 3 days and then not work a lick for 3 days.
The local Sprint store replaced the back red portion of my phone (the part with the camera lens and kickstand) stating it was an GPS antenna problem. I got 30 secs outside the store and tried the GPS....same problem. I went back into the store and showed them and they tried to convince me I needed AGPS on as well. AGPS always worked but is not as accurate as the satellite GPS. The repair shop refused to do more or order a replacement. I just got scammed out of $35.00 cause nothing is fixed.
I got so pissed, I called Sprint. They were terrific. They refunded the $35.00 the repair center charged me of the repair (the rip-off repair) and agreed to send a replacement phone. Awaiting arrival of the replacement but they are back ordered...so, maybe, I'll get a new phone instead of a refurb.
Long story short...I don't know what is causing your reboots. Mine could not be solved by software changes. My phone was rock solid until around a month ago. Then the GPS dropouts and reboots became more frequent until they became unlivable. I think you have a bad device and would seek replacement.

I had the same problem with mine about a month ago. It happened once about a month before that and then a month ago started happening a lot. I finally narrowed it down to how "hot" it was (body temperature in this case). So basically any time that I was in the car it happened. I was able to unroot (you have to make sure you to s-off on) and put a stock rom on it, and take it in with it happening. They took it for an hour and said they had not seen any issues. I finally convinced them and the replaced it with a refurb. I'm okay as long as it works, but it makes me wonder what happened. When I first got it I used fresh for about a week and then went to CM and was on it the rest of the time. I used an SBC kernel starting around the same time and am thinking maybe that had something to do with it... Just as a precaution I'm staying away from SBC kernels.
If I were you I would just go to the store and get a replacement if you can otherwise if it's like mine you won't be able to count on it working...
Good luck

HELP! My phone gets hot and restarts! Please look for more info inside!

Hello dear friends!
HTC let me down Kind of stupid phones indeed at least desire...
I have my phone for quite a time now, it is rooted with unrewoked, clockwork recovery and s-on. I flashed many different roms in the past and everything was brilliant. In a pas half-a-year or so I stayed with only one ROM - MIUI-Au. I kept updating it to the newer versions and so on and on. Never had any random reboot or something. At least maybe it was because of some strange app or something else. But now it started to reboot randomly and constantly!
Phone gets hot abit and it just reboots, and never comes to android homescreen again, until I put out the battery, hold it for few minutes, pop it back and then it boots. But as soon as start to play music, or run a game the phone gets hot abit and reboots again. and so on and on. I thought maybe it was a miui issue. So I tried to flash different roms, but guess what? None of the even boot! The main screen shows and with the same second it bootloops again and forever!... (
Even from recovery it sometimes reboots randomly. So i managed somehow to flash my miui back and it at least boots. But it is very unstable now, I barely can use my phone now
PLEASE WHO CAN HELP ME????
My warranty probably out of date, and my phone is rooted, I dont think HTC would accept it...
any thoughts? friends?

What have you set the CPU max to?
Sent from my HTC Desire using xda premium

Thank you for response! Appreciate, really!! I didn't set it, I left everything by default I think! Because as i said, i even tried flashing different roms, not only miui.
What else could be? By the way, with stock froyo rom If I remember correctly, sometimes it became extremely hot, but I didnt get any reboots from that. But now, it gets just a little bit hot and it seems that this causes the reboot...

Now what I just noticed, I get reboots even when the phone is idle. And it is not even warm!

If its not getting hot then I'm confused lol. It sounds like a actual hardware fault. Sorry I can't help with this one

try and get it taken back to stock if you dare.
The phone hasn't been out 2 years yet, which is how long the warranty is.

Thank you! But is there any possibility to fix it without HTC involvement? Maybe it is not hardware issue ? Can it be because phone is rooted and I flashed many roms to it ? I didnt try AOSP roms since reboots started, I will try to pop in Cyanogenmod or other and see if I will get reboots.
Would rerooting my phone and updating my recovery fix the problem?
and Note: yesterday I tried to S-OFF my phone, but I can't even do that with my unstable MIUI. It rebooted in the middle of the process..

I had a similar problem, apparently it's not uncommon on the early revisions. I sent mine to HTC and they replaced the mainboard.

Thank you for answer! But what if my phone is bought through a contractor?
Can just call HTC and ask the for repair? Or should I contact my contractor first ?

Just give them a call and they will try to help you out. I had a very good customer service experience with them when my desire had some issues.
They will require a proof of purchase though. If you managed to get the receipt from your "contractor" (I am unsure what you mean by a contractor), then there should be no problem.

Sorry for misleading word, I meant T-Mobile. I bought my phone under contract. I think I have a receipt. I even have whole box and stuff of the phone somewhere in my drawer.(just sayin ). So how is customer service of HTC? Poor, good ? I heard you need to tell them that you did a factory reset and that didn't help. Is that true. Also if I will unroot my phone, will they know it was rooted anyhow?
Ahhh....this overheating issue seems common. How they can release faulty phones?? No clue.
thanks for answers mates!

In Singapore, HTC service is really good. Phone was still under warranty.
It took me just one (real) call to confirm a repair order. The first call I was just checking to see what options were available to me.
The second call was an actual repair request. And the third call was me pestering them for a pickup date. heehee
In Singapore, repairs were done via courier. They picked it up and 1 working day later, they sent it back.
Naturally, you will probably need to impress upon them that you tried everything to fix your phone (which I hope you did which includes proving to yourself that it's not the ROMs fault).
You will definitely need to reset everything back to zero. In my case, I downloaded an RUU to totally reset everything back to STOCK, which included removing clockworkmod recovery. You WILL need to create a goldcard for this though so bear in mind that it's not exactly a case of a simple flashing procedure. At least not if you don't already have a goldcard.

Sorry if I overread it at some point, but you speculated at the beginning there could be some faulty app causing this, but you never meantioned performing a full wipe. Have you full wiped yet? Just to make sure it is indeed no software problem.
greets

Thank you for your answers. At the moment I have SuperNova classic ROM. ( 2.3.3 + Sense 2.1) But my phone crashes again and again, it is so annoying and causes me so much trouble.
I never tried a reset or unroot and return to original rom. Im just wondering now, would this help to remove or at least remove those reboots?
Today I was in my work and i was keeping my phone in my jeans pocket. it got hot as u would expect when keeping in pocket and suddenly it rebooten, then it went into a bootloop and started to bootloop 7 times in a row quickly. then again and again. It became very hot at that time.
For the interest, what exact hardware faults causes these reboots and why phone gets even hotter if you keep it on boot loop. If I keep phone cold, the rom usualy stays normal, without reboots. but as soon as I start using my phone, texting or calling for at least 5minutes of using it just reboots.
as I said- really annoying thing :S
I remember my happy times with miui, apps and no reboots Was fun!
cheers for helping!

I would give full wipe / factory reset a chance, and maybe RUU.
At least try it before sending phone to htc.

It is hardware problem, search forum. Fresh ROM without SD card, enabled WIFI and GPS, running G navigation, back of the phone is warm - restart after few minutes.
Maybe someone know how to read info form the phone right before reset? We could understand why the phone is reseting and hopefully add some patch.

Reboot-loop experience
Hey,
i had the same problem over the last few months: In the beginning my phone restarted only when it got hot, but it got worse over the last few weeks, in the end i was not able to use two apps at the same time (music and mytracks) or even to surf the internet longer than a few minutes. The problem did noticeably decrease when the phone was cool - tested by putting it on a fan or in the fridge. Yet, Skype was regularly killing it. As i really love my phone (and especially the AMOLED-Screen!) i did not want to resign. The battery cover contains some metal which is supposed to enhance heat dissipation - so i attached a little thermal pad to the hotter bottom of the phone to improve contact with the head spreader. Unfortunately it did not entirely fix the problem. Yes, it improved the situation a little, but it got even worse after a week or two - in the end i had to turn it in.
So i decided to take it to the Telekom-Shop. They were very kind and told me they would call the other day to confirm that the replacement would have been shipped. It took a few days longer, but i got a phone with the AMOLED-Screen! The employee said it was a used mainboard in a new case, completely refurbished. They only replaced the main unit, i kept the battery, sd-card, charger and so on. Now i have a working Desire again!

[Q] Wifi stuck "turning on" - Galaxy Nexus

Hi all,
I recently sent my GN (Running 4.0.2 stock, yakju build) back to be repaired because my phones wifi stopped working. what happens is that the phone's wifi seems be stuck "turning on", but never actually does. No wifi icon or anything appears. wifi hotspot doesnt work either. I had my GN from about a week after it was released (I'm in australia so that was about the 22nd December), and around the 15th January is stopped working. This issue cannot be fixed with a reboot, a hard reset, flashing stock roms, toggling airplane mode or anything trivial like that, as I (and others) have tried.
Now i have searched a while on google while i have been without my phone and I'm finding this problem is surfacing for other people too. From what i have seen there seems to be a correlation between 4.0.2 and this issue. Also, it seems to happen some time into the phones life; they do not have this issue when first purchased. I am concerned that this may be a recurring issue which surfaces over time, due to a design flaw or some sort of software issue. If so, this problem will start affecting a lot more people. If anyone who reads this has the same problem, could you please post when it started occuring and what rom, build etc (and anything else which may be helpful) you are running so we can shed a little light on this issue. which many more users i am sure will experience. cheers in advance

just incase anyone actually reads this Galaxy Nexus was sent back, and it was found that the printed ciruit board (PCB) needed replacing. More forums have surfaced since i last checked up on this problem so numbers are slowly rising. Once again, post here if you get the issue, we need numbers

Hi same issue i have butni solve i am living in turkey and i use habertürk news and i saw this application make notification wifi turning om.i reset my phone i load factory firmware but nothing happen ...always say wifi turning on...you need to change your system language another still write wifi turning on on screen in eglish and a application cause to this like my haberturk app

same problem
Hi,
i had the same problem, wifi mac info was not showing anymore on the Nexus. Reboot and factory reset didn't help. Wifi wouldn't come on anymore.
Ask for a replacement, that's the only thing you can do

Can i ask what version of android you guys had? I'm wondering if this is going to be a recurring problem with hardware due to software issues or if it is purely a design flaw (PCB burning out, etc..) Cheers!

I have the same problem which happened last Saturday and it frustrated the hell out of me, i flashed to different versions of OS....didnt help...
restored to factory firmware and didnt backup the pictures and stuff on the phone!! (FML)
and brought it in to Fido on monday to have it serviced....
talking about bad luck...sigh....
they told me the turn around time is 10-15 business days... (N)
will report back once i hear from them

Before the issue happened, did your phone have any other issues? Say heating up while charging or running the WiFi?
I received a device in for repair with this issue and the customer reported it got really hot before the issue started happening. Everything looked fine on the motherboard - the WiFi antennas were intact. Reloading the software did nothing which means it's a hardware issue..
So very strange. I wonder what's causing this.

i remember when my wifi stopped working i was running 4.0.2. I was actually on holidays in Japan at the time and i was wifi hopping quite a lot around the airport (i was walking around and the wifi would go out of range, latch on again... etc) not sure if that had anything to do with it. Hopped on the plane home and i remember i was on airplane mode using an app called colornote. the phone hung pretty hard and i had to pull the battery. rebooted and tried again and after 10 mins, phone crashed again doing the same thing. Got home and the wifi wasnt working. Not sure if any of this had anything to do with it, but maybe. Didnt notice any overheating, but then again i was around snow haha

hi mrmiklepower
just wondering if your phone has been good since you got it back from repair?
i noticed the phone would reboot itself over and over again after i flashed it back to the stock rom. I just called the third party repair shop that my carrier sent the phone to, they told me its still being fixed.
Oh i hope they will return me my phone soon.

My phone is actually still being repaired also. It's been a total of 2 months since i sent if back! they contacted me and all i know so far is that the phones PCD needed replacing. when my phone arrives i will update as soon as i can. should receive it sometime this week, but its not certain. the majority of my ownership of this phone has been me waiting for its return

Holy mother of lord...
I actually called the third party repair shop that my carrier uses to check on the status of the repair. And they told me its actually In quality control which means the problem was fixed and they're just testing it before they send it back to the store where I brought the phone too. Hoping they'll send it in on Monday so I can either pick it up on the day of or the next day.....keeping my fingers crossed.
Will keep you posted on the status of it too.
Sigh

Ok I got my phone back today.
on the reference sheet I got from the repair shop
it states REPLACED PBA, BGA Failure
I looked it up online and PBA means Printed Board Assembly
which probably means the motherboard was defective and had to be replaced.
and now the phone is working fine. So i guess when this phone was made, there were some flaws with the motherboard on it, thus causing this problem.
Anyways, I hope this information helps with others who experience the same problem

Thanks for letting us know! O got mine back today with the same thing. So looks like there is no way of fixing besides sending it back. Good luck to anyone else who gets this problem

So it seems there's no fix for this?
I've been doing some research and it doesn't seem anyone can fix this.. I tried reflashing, wiping every possible thing, etc.. even flashing the stock software via odin. Still no luck.. It seems that we are indeed stuck with sending it back in for a supposedly defective part which seriously blows.
My other question is.. you guys who already received your phones back, did anyone end up with the problem again?
PLEASE if anyone knows how to fix this.. chime in!!!

I had an issue similar to that with my transformer and to fix it I just flash a new kernel im not sure itwill fix the problem for you but it's worth a try

Since getting my phone back the problem has not occurred again. I don't think there is anything that can be done as a component needed to be changed apparently. Good luck :/

Thanks, when returning to stock it flashes a new kernel. Also tried it again for the hell of it with faux's kernel, still no luck .

This sucks! This very same thing happened to me yesterday! I Odined back to stock.. no luck! Now after finding this thread, it looks like a hardware issue! That blows! I'll have to give Sprint a call tomorrow!

Hmm sucks to hear it's still cropping up around the place, I heard someone say this issue entered quality control. But anyway, if it helps I've had my phone back for about a month and a bit and its still going strong. hopefully it doesn't happen again though. good luck, hopefully it won't take too long for your phone to come back!

Hi,
I'm with Telus in Canada and had the exact same problem and had my GN repaired. It took only 2 weeks and I just got my unit back. I had already read a lot online about this issue so I asked the Telus rep to tell me what the issue was. She told me that the report states that the board was replaced. This is definitely a hardware problem. I'm hoping that the new board doesn't have this problem and my phone won't need to be repaired again,
I run 4.0.1 on my phone. Telus hasn't released an update yet. I was going to update mine by switching to yakju, but that's when I noticed that the wifi is not working and I thought it's not a good idea to change the stock ROM.

WiFi and Bluetooth stuck at turning on.

For the past two days I have been having issues where my wifi and Bluetooth wont turn on. The problem started after rooting. I unrooted and returned the device to normal status and no binary downloads but eh problem persists. right now both will turn on and off fine but every once in a while they get stuck at turning on. after a few resets and simply waiting everything goes back to normal but this has happened at least 5 times since yesterday. On my s2 I had a similar issues with GPS. the only solution was to do a factory exchange. I am already set up and the replacement will be sent once the phone is back in stock. I was just curious if anyone had a similar problem and resolved it without having to exchange the phone.

I haven't had any problems today but I know as soon as I loaf all my apps back it will happen again. To be on the safe side I am just going to return it before it gets worse.

I'm having the same problem. Did you go through T-Mobile or Samsung for your replacement?

Went through tmobile. It's been good for more than 24 hours but I don't trust that it won't come back. Then phone is back ordered original would have had the new one by now.

Yeah, it actually started working for about a day, but stopped working when I left the house. Just went to T-Mobile to process the exchange, but they're telling me they can't do it due to the IMEI stating it not being "sold" through a T-Mobile store. Which is odd, because I bought it at a T-Mobile store at full upgrade price while my roommate was working. I have the invoice somewhere here...
Time to jump through hoops to get this replacement.

I noticed it usually gets stuck when I leave the house as well. Do you use airplane mode a lot? when I am home I usually keep my phone in airplane mode with Bt and wifi on. the first time this happened I also noticed the wifi looked as if it was connected when i was a mile from home and i had to power down to get a cellular signal. I have had the phone since day one and this just started last week after I rooted. Since many people have rooted and this isn't a known issue I guess its best for us to return the phone and see what happens with the next. Find your invoice and they have no choice to replace it. If you paid by credit card that should work as well. Just show them your statement.

I don't use airplane mode at all. T-Mobile gave me the run around so I decided to go through Samsung for my replacement. They originally wanted me to send my phone in for repair, but no way am I going to be without the Note for more than a day.
A Samsung Experience Shop popped up in Best Buy just outside of Chicago. The woman running it wasn't a Best Buy employee, but a Samsung Specialist. She troubleshooted my phone (Factory reset it, even though I told her I already did) and Wifi and Bluetooth didn't work at all. She called her contact at Samsung and they're having a replacement sent to the store that I'll pick up when it comes in and exchange. Good news is that I don't have to send in my Note and have to wait on it!

I haven't had a problem in two days but my replacement is on the way so I will just wait and see if it happens on my new one

OP, I had the exact same issue as you. Wifi and Bluetooth just stopped turning on, intermittently at first. After trying to figure it out for a month or so I decided it must be a hardware issue. Wifi and Bluetooth are controlled by the same integrated Broadcom chip, which might be a common failure point.
I sent it in to Samsung, and they have had it for 2 weeks now... I just got word that it's fixed and shipping back to me. They replaced the PBA (main board).
I have a question. How did you get service through T-Mobile? I bought mine at a T-Mobile store and I was outside of the 30 day return policy. I was under the impression I had to go through Samsung for a defect, or T-Mobile for an insurance claim (pay deductible).

I just called tmobile and they sent me a new one. I had a problem with my black berry a few weeks ago and thought i had to send it in for repair but tmboile sent me a new BB as well. usually most phones have a year factory warranty and tmobile is the one that handles that. My phone hasn't acted up in a few days but i am going to keep the replacement and send my old one back just to be on the safe side.

Anybody with a solution for this? Mine started acting up 2 days ago and I'm now a grumpy man.

Are you on custom Rom, and which Rom is it if you are
Possible fix: Odin to stock(sure way to check, or redownload Rom and wipe three times and reflash Rom

I'm now in Malaysia for another 3 months and a half. Won't be able to find any T-Mobile here. Any suggestion?

if you are on stock already, then it possibly is hardware

My problem started after I rooted using toolkit. I unrooted and rooted using stock injected but the problem persisted. I had to return the phone so I unrooted and used triangle away to get my phone back to normal. I did a hard reset and had the problem one more time. for the 5 days it took my new phone to arrive i didn't have the problem more than once. I also remember having a problem with my printer saying it was connected but i couldn't print from it until i reset the router. I think the time my phone started working find again was when I reset my router but i didn't put all this together until recently. I noticed that the only time I had the problem was when I had wifi and BT connected and went into airplane mode. then when I came out it didn't always connect back like it use to. I also noticed it when i had wifi connected and left my house. the wifi looked like it was still connected even though i was more than a mile form home. So maybe it had to do with my router connection and a bug where the phone thought it was still connected. if anyone is having this problem try resetting your router and see if the issues persists.

I used the toolkit in the original development thread, could it be the method you used for rooting caused that?
Is the problem there if you connect to Wi-Fi on a different router, like someone else's

I never tried connecting to another router. My problem seemed to be that it never properly disconnected from my router so when I came out of airplane mode of couldn't connect. Also bluetooth was stuck.

[Q] Major problem with my stock ATT E980

Okay, I originally got this phone as an upgrade over my HTC Inspire in July. It worked great, minus a few random reboots every once in a while (if I left it in my pocket for a long time or if it was really hot in my car it would do this, but that was it). Then, about a month or two ago, I rooted it and installed a custom ROM. I noticed that a bunch of my files were missing from my internal SD card, but I wasn't too worried about it. Then my phone started acting really weird and got stuck in a bootloop. I was able to boot into recovery, but I ended up using the LG Flash Tool and went back to bone stock. Still had the issue, except I noticed that my signal would drop, and then it'd get stuck in the bootloop. So, I contacted AT&T warranty and they sent me a replacement. Now the same thing is happening to this one. It gets warm, loses cell signal, then reboots, sometimes a bootloop. This phone hasn't been rooted at all, it's been left stock. So I contacted AT&T and the guy in warranty said he thinks it's the battery, but he didn't have any in stock so he couldn't send a replacement. So I was thinking it was the battery and called LG after it seemed to get worse. They told me that they could replace the battery free of charge if I send in the one I'm using first. Since this is my only way of communication, I contacted AT&T again, and they're sending me another replacement. (Said if this one screw up too, they'll give me a different phone all together). The guy had me download some AT&T remote support app and he looked at the battery health and said it's reading fine, and that because it's reading fine, he didn't think it was the battery. :|
Here's the weird thing, about two weeks ago, it went into a bootloop. I took out the battery for a minute an tried to put it back in. Nothing. I plugged the charger into it and it basically told me that it didn't have enough juice to power on. (battery was at ~40%). So I took the battery back out and tried again. This time it came on.
Then last friday, I was jammin out to music while I was working, it would reboot when I unlocked the phone. (battery was in upper 90%'s). I plugged the charger in while it did this and everything came up as it should. But after taking it off the charger and trying to do more work, it happened again and again.
Like I said, this phone is straight from AT&T and has not had anything flashed onto it by me, hell I never even disabled all the AT&T bloat this time. I've tried a hard reset, and it didn't help. Does anybody know what would be the cause of my problems? I really like this phone and really hope I can get this figured out.
EDIT: Forgot to mention, the phone still has its IMEI number and it has the value pack update.

Got the second replacement in the mail today. It hasn't screwed up yet, but only time will tell.

Wow hope this works for you. I just got 3 Optimus G Pro's on 12/30/13 and all 3 of them to date have not had any issues. 2 black and 1 white. 2 which are running stock. 1 stock which has had a bunch of the bloatware yanked (that we could get off of it). 1 stock which has had nothing pulled, everything left the way it is. And the 3rd one (which is the one I use) which I rooted to CyanFox 4.4.2 and later to CM11 4.4.2 Nightly and haven't had any issues like the ones you've explained.
Good luck though hopefully your issue is gone. Seems like a nice reliable phone (minus LG not wanting to support it furthermore ).

I really hope my issues with this phone are done too, I really love this phone. If I don't have any issues, it's going to get rooted and updated to KitKat. Otherwise, I'll try to get AT&T to give me a MotoX or a HTC One.

Yeah I like this phone with KitKat. Looks like a larger Nexus 5
Only problems i'm having with CM11:
1. ATT Visual Voicemail will install but upon playing voicemails program will freeze and crash
2. Tried Google Voice however you can only hear the voicemails through speakerphone, headsets, or bluetooth. Voicemails will no play through earpiece.
3. CM11 doesn't have Screen Recorder yet (Which CyanFox did although CM11 is still fairly fresh).
4. I would like to have the LG Camera app back! Dual video recording and some of those other features are gone with the android stock Camera app. Need to look into porting that back over to KitKat (if I can).
That's bout it though...

Haha yeah, this phone is beautiful with stock Android, I just end up missing certain touches that LG puts in their overlay.
BTW, this phone is doing the same thing as before. I strongly believe it's the battery b/c when it went into a bootloop, I took out the battery it was warm, so I put it in front of the AC for a minute to cool it down and it's been working fine since. So, I'm going to call AT&T and see if they will send me a battery, and if they can't, I'm going to have to send this one in to LG and be without a phone for a week...:'(
UPDATE: AT&T told me "since we have tried everything else-hard resets, replacement phones- and nothing worked, we will send you a battery since it's the only thing that has stayed persistent through this ordeal. We just got some in stock and are sending one your way. If the problem continues to persist, we will replace the phone again." IT'S ABOUT TIME!!!

Just curious, but what if I continue having this issue after I get my new battery? Should I try a similar mah zero lemon battery or just have att give me a different phone altogether?

i think there is an issue with the battery and whatever cable you use to charge the phone.I had to Lge980 when I used a thin cable I have in my room sometimes it did not charged at all and or shut down itself even when the battery had half charge ,sometimes it showed full charged but if I plugged the phone to a thicker cable connected using the oem charger or a usb 3.0 port at my laptop it showed the real charge level at 1/4 charge.I myself could't do anything since I got the phone second hand but as long as I used thick cable connected to a oem charger usb 3.0 or eben 2.0 I had no had any issues.

how'd it go?

I've had the exact same problem with my E980 and the refurb they sent me. Contemplating a battery replacement now. Did a new battery fix your boot loops?

If you want to stay on stock i recommend going to jellybean TOT 10k and rooting and installing a custom recovery back up the rom, and flash hkfriends kernel, and see what happens if you raise or lower your phones voltage, that might be the problem with it rebooting.

THE NEW BATTERY SOLVED THE ISSUE, BUT ONLY FOR A SHORT TIME. I upgraded to an HTC One M8 since, and haven't had hardly any problems with it, aside from the death star's BS

Thanks for the response. I talked to the techs at an AT&T direct service center and they told me it's a common problem with the Optimus Pro. I'm on my third one in 8 months now and this one started randomly powering off within 15 minutes of when I took it out of the box three days ago.

Yeah. My issue was the battery for sure. Make them replace the battery and it should temp solve the issue

From what I read on the first e980 i had these phone tend to have a hardware problem where the power button is creating the same issues as OP. Some refurbished e980s have the hardware problem solved.
