Not sure where to begin, but any help given is appreciated

I purchased a G2X online without the battery or back cover. So I go on ebay and buy a back cover and a battery.
I try to power it on, but holding the power button does not work. If I hold the power button and the volume down button simultaneously, I get the LG Splash screen and the bottom button lights come on, but then it shuts off. And it only does this when it's plugged into a power source.
Does this mean my battery is dead? Or has someone tried to flash something incorrectly and now the phone won't work? Again, I'm not even sure where to begin troubleshooting.
Much obliged

Is it a third party battery? You may want to try buying an official one from T-Mobile, pretty expensive but at least you can have some assurance that it'll work (if that is the problem).
It may not be the battery though, because my phone will turn on without a battery while plugged in so, try NVFlashing clockworkmod recovery and then see if you can boot into clockworkmod recovery, if you can then I think everything should be okay.

Yep sounds like a corrupted cwm install just search nvflash its super easy one click program.
If not get a new battery on Amazon or something good luck
Pin it to Win it.

Just a heads up. Typically replacement phones are sent out without a battery or back because they are a replacement. The company expects the customer to use his old battery and back from his previous phone. So people sell their old phones which may or may not have fixable issues. Therefore be very cautious when purchasing a naked phone.
That said. I would search xda, see if you can connect your phone to a computer and get your custom bling on.

Thanks for the input guys. I just realized in addition to the weird boot issue, the battery connecting pins inside the phone are broken. What a nightmare
If this phone was released last april, can i send this to the manufacturer for a warranty repair?

Yeah, you HAVE to be the original owner. Not have a receipt as T-Mobile checks who was the first person to put their SIM card in it.
Why would you buy a phone without knowing if it works or not anyways?

Nexus S won't power up?

I recently flashed CMRex with Kejar's 4.1.1 gapps and was going about setting up my device. I got everything set up how I like with all the apps I wanted downloaded and running how I wanted them. I then ran the v6 supercharger mod that I had used on my past two roms with no problem whatsoever. After finishing the set up of the script, I rebooted my device and all was well. I went to browse on craigslist's mobile app, then I saw something I wanted to google, so I opened my browser. My browser took an ungodly amount of time to load my homepage(google), and wouldn't respond hardly. I couldn't get the touchscreen to respond. My hardware buttons did respond and I got haptic feedback from them, but no response on the screen. Eventually, after numerously pressing the home button, I got a message saying the browser wasn't responding, selected ok to close it, then back to the non-responsiveness of the touch screen and hardware buttons. And then another eventually later, after another multitude of home button presses, I got to my homescreen but everything was laggy. The most lag I have ever encountered with my device since I obtained it, not to mention that my device was beginning to heat up. So, I decided I would power off the device, remove the battery, let it cool down, and then replace the battery before powering it back up. Well, lo and behold, I did just that, went to power back up my device, and there was no sign of life at all. Tried to get into the bootloader, no response. Tried a normal boot, no response. Tried to plug it into the charger to see if it would charge, no response. Well, my girlfriend told me to leave the battery out for a while and leave it alone for a while before trying it again. So, I played some MW3 for about 45 minutes to an hour, repeated all the above, and still no sign of life. Can anyone help me out? (I don't know if this is supposed to go into the Q&A or here, so I just post here.) I'm so distraught at the possibility of losing my phone, that I'm finding it hard to cope at the moment. Should be thinking of ways to gain some money in order to purchase a new device or is there still hope?

what a long message.do you have any point form here?
i hope you solve the problem .

Do you have access to a separate charger? You can try charging your battery there and see if that works. Did you try connecting it to the computer? Maybe that will show some sign of life. Also, how old is your phone and did you over clock?

I did not overclock, I do believe that my clock speeds were at the kernel default, either 100/1k, or 200/1k. Not sure which, but definitely one of those. The only other charger I would have access to would be my mother's HTC charger, but I will try that and connecting it to the computer as well. Well, I'm not exactly sure on the age of the phone because I purchased it off of craigslist, but it's in great condition. Only had a small scuff on the top left corner, but I know that has nothing to do with the age of the hardware. ): Could it possibly be that my battery decided to die for some reason? I've been having horribly battery life lately. Granted, I had horribly battery life when I got the phone, but it's gotten worse and worse since then.

My Nexus S wouldn't start but gave a flash on the screen when the battery was first inserted. Just got it back from repair and it was a motherboard problem. Was looking at a Huawei G300 as a cheap replacement if the repair wasn't covered by warranty (which it was). Good luck!

Thing about it is, I bought the phone off craigslist so I have no idea if its covered by the warranty still. Should I try calling samsung and find out?

Sorry for my late reply! You could try, but u guess you can get a battery from Ebay and check if that solved the problem. Or if you have a friend who has one...

I'm the only person I know that has this phone. And I guess the battery will have to wait till I get a job, but if im waiting that long, I'm just going to get a new phone all together.
Sent from my SGH-i997 using xda app-developers app

Testing the battery can be done differently, do you have a multimeter? Maybe your neighbours have one, it's a common thing. You can measure whether it has any power left. If you measure low voltage (below let's say 3400 mV), then it could be battery related.

Many reports on dead Nexus S with 4.1.1. Mine included after flashing CM10. Sent for repair 10 days ago and still waiting...
If you've got no warranty, perhaps time to buy a new phone? Bought myself a new Galaxy Nexus.

I would like to get a new galaxy nexus, but I have no money to do so. I'm currently trying to get a job and i m going to save up for a new phone. Im either going to get an s3, a galaxy nexus. Either one of those two or the new nexus if it comes out.

i727 skyrocket stuck in continous reboot loop and doesnt get past start screen

I I have a Samsung Galaxy S2 Skyrocket i727 (with stock firmware and ROM), i dont have a SD card and not too many apps installed either, maybe 10-15 apps at most. Today while the phone was in my pocket it just went into this continous reboot cycle, it reboots, gets to the AT&T splash screen and then reboots again and then this goes on forever.
I googled the hell out of this issue but cant seem to find a solid solution and hence hoping u guys can help.
I cannot get into recovery mode cause it never gets past the splash screen
I cannot seems to perform a hard reset (power button + volume key) , it just reboots again.
I tried plugging the phone and connecting via USB but it doesnt help either, it reboots before the computer can detect the phone.
Hope u guys can help ? life without android is no fun...

I had this same issue with my LG Phoenix, I tried the needle around the power button, and that popped it back to normal. Apparently I held the button down to a side and it got stuck even though the actual button part was in it's "normal," position.
However it did reboot several more times after I got it unstuck. I did remove the back & battery, & unplugged it. Let it sit for a few minutes, after that I put the USB cable back in, then pressed the power button, put the battery back in and pressed the button again, and it went through the normal reboot process.

Just wanted to give you guys an update that i started cleaning the part around the edges as some folks suggested and that failed. then tried smacking around and blowing air into and that failed. Then took the entire phone apart and cleaned it several times using different techniques and sad to say that it all failed and i m SOL.
Bummer but it is what it is and i was quiet happy with that phone.

Where does one find a power button for the skyrocket (the one attached to the motherboard)? The closest thing I could find was this:
http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-s-ii-skyrocket-power-button-repair/
It is a repair service though and I live in Canada, I would prefer if I could just order that part. I have been to few repair shops that cant do anything because this power button is hard to find. I opened up the motherboard and the power button clicks fine, so I think it probably has to be replaced.

Freezing the phone
I had the same issue, came here and read all the things about the stuck power button and needing to replace whatever is beneath it. My friend works in aerospace and had told me about one of the things they need to worry about is temperature causing wire shrinkage due to temperature. For whatever reason, I decided to use that logic and throw my phone in the freezer wrapped in a dry rag. 30min later and the phone finally worked after 8 hours of the boot loop/no boot. That was around November and I haven't had an issue with it since (until today, but it is a different issue).

I have just fixed mine!!!!
There is a little battery on the circuit board when you take apart the phone. It looks like a small watch battery. Top side is and bottom side are opposite polarities.
I had the exact same symptom. Sometimes just pressing the power button momentarily would bring up the power down menu, then I knew to press it a bunch of times because it was stick. If I didn't eventually it would turn off and vibrate constantly. It kept getting worse.
I measured with an ohm meter and the button itself seems fine so I figured maybe the digital logic relating to the button itself is faulty. So I shorted the little battery on the board (do this only for a brief period, no more than 1s) and put it back together.
Its behaving perfectly normally. I was also getting weird artifacts during video playback before, kind of like what failing solder would do on a bga gpu. It fixed that too.
So I think its similar to that problem some laptops have, where it wont turn on until you remove the battery, hold the power button down a couple times, and then plug it in. It seems a complete circuit discharge fixed this problem at least for me.
If people are interested I can try to find a picture
removed link
In that picture its the silver shiny metal circle. To short it you connect the bottom soldered part to the metal plate on top of the battery. This comlpetely drains all circuits.
So I think a lot of these problems are caused by a phantom charge. In any sense, Im very very happy
Also this could explain why the fridge method worked. Cooling the battery can significantly drop its charge, however I would advise against the cooling method if possible.
EDIT: blah cant post links... if anyone needs the image pm me your email

You'd need to find a friend or local electronics repair shop, but I ordered some here:
http://www.etradesupply.com/oem-samsung-galaxy-s-ii-skyrocket-sgh-i727-power-button.html.
The buttons are $0.99 USD if you buy 2 or more ($1.05 CAD), but 5-7 day business shipping is like $16.99. Still cheaper than a replacement phone, and it's an easy fix for an electronics person or electronics/tv/computer repair shop... At the rate these power buttons have had reported failures, and for the price, I'd get a couple of them in case the replacement fails in the future...
If my wife keeps squeezing the power button on her phone when some crappy app she has wigs out, I'll be needing my second button sooner rather than later...

why when one person says it something everyone band wagons on that idea. i actually had the same issue my skyrocket couldn't go pass the "samsung" screen. all i did was flash a new rom or i just restored an old backup

Then it was user error or a bad flash. And that's software, not hardware.
Skyrocket power buttons are known to fail. I believe Samsung has even acknowledged this.
When your phone randomly goes into a 1-second vibration cycle, sometimes showing the reboot menu beforehand without pressing the button, more than likely it's the power button that has either failed or is sticking.
With my wife's phone, the button was not sticking, and usually lightly tapping the phone at the right angle on your lap or the counter would break the vibration cycle and let it boot up, until the next random power button press and vib cycle would happen.
Button replaced, same exact ROM, and problem gone. :thumbup:

I have a repair shop and i fix these issues with no problem. the only issue im located in Puerto Rico. when the power button gets stuck is because of heavy use, a fall or something that makes a lot of pressure to it and the copper contacts inside the button stay making contact. this is know to happen to i727-i717-i997-i897 and some other galaxy s1 s2 models.
i attached the picture of the power button.

[Q] Fried My Optimus 3d

Since installing ICS i've been having problems with my getting my phone to charge. I'm not sure if this was actually related to ICS or just coincidence. Anyway, the battery had died completely and the phone would not power on. I came across some info that mentioned cutting the end of a usb cord and attaching the red and black to positive and negative of battery. I tried this and sure enough the phone powered right up. Now I decided to do a factory restore using lg mobile support tool.
Sometime during the restore process the phone powered down, I wasn't watching so i'm not sure how far it actually got. When I checked the wires I noticed the red and black from my usb cable had twisted and made contact. Now of course the phone won't power up at all. I believe I probably fried something when the red and black made contact but I'm not sure what or if it's fixable. If anyone has any ideas on what I might be looking for i'm all ears. I'm going to take the phone apart when I get home and see if there are any obvious problems.
I have tested the battery, and it seems to have power, so it's not the battery.
On a side note I really can't wait to get a new phone, this thing has been nothing but a headache for the past 2 years. Hate to say it but, I think it's just about time for an iphone.

How to fix a phone when you have "deleted" its ability to charge

So I just did this.
My phone was dead. A paperweight. It in its coffin, its box.
Until I received a message from one awesome person who told me I can still save my phone.
Basically, what I did was wipe out my recovery and wipe a lot of other stuff using TWRP recovery and using format data and advanced options.
My phone wouldnt even charge so I gave up hope.
Then I received an awesome message from an awesome person who explained how I could still access my bootloader and guided me through this guide as to how I can flash in a stock OS- https://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
So I told my brother to charge his phone, and then took mine apart. and then took his apart. then used his battery to turn on my phone and flash the image. I did it.
then I turned my phone on and it got stuck at the google screen. Similar to the problem the first time around.
I turned it off and tried to charge it and thankfully I could. So it wasnt as bad.
So I flashed again and this time we got to another screen. Still google but a better animation.
It was taking too long to load so I turned it off and then on again.
And voila. One of the quickest boot ups I've had with the Nexus 5.
So that's how you do it. I'm not 100% sure if this is the right place for this and I apologise for the rantish style of this post but I am so happy about this.
There was a casualty though. My brothers phones power button was broken. Meaning I could only turn it off once and I wouldnt be able to turn it on unless I fix the power button.
I have not been able to fix the power button because the inner power button is broken. I,e I think it needs to be soldered back on. So thats one phone which died in order to save another.
I could look for help with someone in my family who knows how to solder stuff on and see what we can do.
Does anyone know any way I could get away with this without soldering?
even if it means I can only use the power button once. As in like, if there's any way I could turn on my phone, even just once, but then I dont need to solder?
I can keep my phone charged all the time after that...

The power button to turn it on is a very cheap piece... Think about a 2 USD 10 pcs.. buy it on eBay and take the mobo to any place that could do the job (take the old button apart and put the new one) it's sounds like a big deal but it's not
Good luck mate

Thanks man
I opened it up and the power button seems fine. Its just been separated from the motherboard so it needs to be soldered on so idk why I would need to buy a new power button.
I have no experience with soldering stuff so yes I am going to take it to a shop and ask the guy to repair it.

Still recommend to get a new power button, you'll have to go to a shop and ask somebody to do the job, it's better to do it with a brand new button
