Well, as always XDA developers is what you use when noone else helps you, my freaking BA is acting strange:
1. The phone doesnt turn on when the battery is in. Tried charging the battery 100% and switching it on but it just doesnt turn on.
2. Now when I place the BA in the cradle, the phone turns on but it just keeps on restarting.
Somebody please help me out.
The phone worked fine until when I tried to tape the body and the battery with cello tape, that is when it went dead, and now I have the two problems mentioned above.
Help me guys,
Thanks a ton all.
try a new battery.
and check the battery lock..

You might have messed up the pins connecting the battery to the device. Also, the little lock for the battery could be damaged as well. Finally, your backup battery could have died also. Hopefully this will give you some guidance towards the root of the problem. Chef has a disassembly guide in his tutorial.
well thanks guys for those responses. My updates are:
1. Since the battery was over 3 years old, I have ordered a new battery (yeah i know i should've checked with another battery first but damn noone else i know uses this phone). So till my new battery arrives I just got to wait.
2. Regarding ezthunder's replies... well I checked the battery connectors on the phone, they seem to look alright to me (physically), how do i test them to check if they're alright, pls help.
Also, regarding the backup battery, damn i would now need to search the net to find a new one.
The battery locking clip seems to be fine and is locks the battery in place, if this is damaged, I'd be freaking damned to try and get this one fixed.
So guys, any DIY suggestions to get these things fixed would be welcome as I dont wanna brick my BA, freaking just put in a new LCD digitizer.

Let us know what happens when the new battery arrives and we'll go from there.
well my battery arrived yesterday, i put it in and tried to switch it on but alas nothing. Charged the battery full and put it in but no start up.
Just the same old problem, phone keeps restarting when in the cradle but nothing when out.
Help me guys............
Well still no response from the forum, however, I have a few updates and hope this could make it easier for someone to figure out the problem:
A strange thing happened yesterday -
1. when I disconnected the flex cable of the buttons and the keypad on the front panel from the main board and put the entire thing on the charging cradle. IT WORKED. I mean it didnt do the restarting problem, it worked perfect. However when I took it out of the cradle, it wont power on. While it was on on the cradle, i checked the internal battery and it showed 100% charge, which means that the internal battery is good.
2. Now back when I connected the flex cable to the connector on the board and power it on - nothing happens and when put in the cradle - the same restarting issue right after the statup screen.
So based on the above - what are your conclusions, is there a problem with the flex cable connector but then in that case it should start when taken out of the cradle.
And yes, its a new battery that I just got. So guess its not a problem with the battery...
Help me guys. I really want to get back my BA... it was such a pleasure to see it working in the cradle with mentioned in point 1 above.
PS. I left it on the charge for the whole night yesterday but no change when taken out of the cradle - just desperate to try anything to get it to work.

Judging from this, it seems that there is a problem with the motherboard itself. I could be wrong, but that's what it looks like to me. You can probably get a new BA from Market Place. I have seen a few members selling them lately.
*bump* still waiting for some good soul to help me out with the prob... i really dont wanna lose this phone...blue angels are real beautiful babies to have around...
First of all I read all the possible posts here in the XDA forum about this problem but no one was able to help me :s
I was listening music with my cellphone than it crashed and turned of from nohting. My first thought was "Damm, it crashed!" and I removed the battery and after a couple minutes I put it back and than the cellphone never turned on again. No battery status is showing up, no leds, odin and flash mode doens't work either. I don't no what to do :s
I tried this:
◘ Unplug from USB, remove battery 5 min, put it back
◘ Odin and Flash mode
◘ Turn it on without battery on pc
◘ Turn it on while recharging
My GNexus model is a I9250 GSM.
Could you add some more details? How long the phone's been in operation, refurbished?, rooted?, your current ROM, kernel, radios, advanced kernel settings such as voltage changes, any tweaks, battery type, temperature.
This exactly happened to me on my DroidX. I spent 2 weeks trying everything to revive it including taking the phone apart before adding it to the pile and getting my current GNexus Toro.. so I know how much this sucks. I'm not an expert on phones bricking but I know that connections can go bad or come loose, especially if the phone has been dropped or other impact, components start to lose their integrity over time and voltage shorts 'burn out' op-amps. You mentioned listening to music, so I'm wandering about the IVA components burning out, which usually has voltage too high especially on boot... Hope you can get it working.

Well first of all I thank you for your concern and my phone is on again, thanks to my uncle. The phone is '4 months old', I rooted last month, bootloader unlocked and I was using samsung stock rom (4.2.1 JB). Yeah, that really suck monkey b*lls. If you got the same problem as me (I really hope not) that's what you should do: First remove the battery, plug the charger and than put the battery back. In my case, It kind "shorted" the battery and my phone is back on. I was reading posts and posts and discovered that GNexus has this problem and a lot. Dunno when it can happen again but I really don't want a paperweight. Once again, thank you!
Glad you got your Nexus back up and runnning. Thanks for posting back with details after you figured out the problem and got your phone working, +1 right there. There's always a good chance this will help out someone later on. :good:
Confirmation: balums worked for me
balums uncle's solution worked for me: specifically, (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button.
Thanks balums!
Does anybody have technical (design/EE) insight into what would cause this?
This was starting from a device that appeared totally dead.
The battery was *fully charged* (and showed up that way immediately when the device finally booted).
I had done the obvious things of removing/inserting the battery, cleaning contacts, checking the USB power connection.
Was about to pull it apart when I saw balums post, saving me huge time.
Device is about 16 months old. Stock OS and settings. First time this has happened.
Search terms:
CDMA (Verizon) Samsung Galaxy Nexus -- SCH-i515.
Phone won't boot. Device won't turn on. Won't start. Dead. No worky.
Thanks,
Seth
Awesome! You trick worked, balums!
Interestingly I also have the standard stock version of OS and Hardware which I bought 14 Months ago (nearly to the day). I was surfing over WiFi yesterday evening and when I turned the phone off I noticed the screen getting grey for a moment, not black. And this morning the Nexus just didn't turn on.
Anyway, thanks for the solution, have a nice day!
That is very odd because my i515 also did the exact same thing and I have owned it for 15 months. I can't wait to get home and try this trick. More to come.
Drew
Thanks!

Hey Balums,
My GNex didn't turn on this morning and I was really confused as to why it would do such a thing, until I saw your post. Thanks a lot for posting your uncle's remedy!
It fixed mine!

bookmarked. thanks op.
Galaxy nexus wont turn on or charge.
I tried (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button but my galaxy nexus still dont turn on. i have 4.2.2 stock rooted. i was downloading something and my screen become weird in colors and i cent use the phone. i turn it of and now wont turn on again or charge.
after unlocking and rooting i installed this touch recovery from google play. [ROOT]Recovery Tools
Excellent! balums' suggestion helped me. I thought I had tried this before but apparently didn't quite get this in the right sequence.
The only remaining issue I have now is that when it does turn on, I've got the thunderbolt on the battery indicator, the phone says it's charging at the lock screen, but when I go to Battery under Settings it says that the battery is discharging. This effectively has my phone in a state where I can't unplug it (battery is too low but it also doesn't appear to actually "charge"). I tried replacing the Micro USB charge port PCB board and came up with the same results. To me, this seems like a problem and may indicate a motherboard or battery connection issue. I used the "Battery Monitor Widget" and it indicated that it was getting AC power. Any thoughts?
Thanks to XDA and Balum's suggestion! I thought my phone just died! It was on 70somethign % battery last I looked, connected by USB to the PC and I don't know if I turned it off and walked away for a while or if it turned off by itself, but it would not turn on no matter what I did after I got back to my desk. It is on Android 4.3 takju stock not rooted.
Thank you all again for the instructions on how to revive the GNex!
Samsung Galaxy Nexus won't power up
I got a Samsung Galaxy Nexus. I got it from my cousin and therefore don't have any information about the rooting status as well as the ROM but i guess it was running stock. The phone won't turn ON, it is not detected in the computer. No LED or any other indication. I tried the above method which worked for many people but it failed. What is special about the phone is that the upper part of the screen is heating up more as compared to the rest of the phone. Can somebody help me fix this? Is this a hardware issue?
I have the EXACT same problem as you do. I have no idea where to start to try to fix it. I took a picture, then lines went squiggly across the screen, then it flickered, and died. I cannot power it on at all. I tried Uncle's tricks. No luck.
Anyone have some ideas on what to try? Thanks.

Also having the same problem. My Nexus has been rebooting randomly for the past week or so, and finally, this morning, it refuses to turn on at all.
It's a Verizon Galaxy Nexus running stock, but it's been rooted. I'm using the extended battery. The trick that was posted earlier in this thread doesn't seem to work for me. I've tried multiple USB cables and power sources.
I'm going to try the standard battery when I get home, but I'm not expecting positive results.
Work-around
About two months ago whenever I turned my Gnex off, it became totally unresponsive to all attempts to start again. After a lot of trial and error, I discovered that if I pulled the battery for 30-60 minutes and reinstalled, it would power on normally. I have completely wiped and rooted the phone and the problem persisted.
Today I thought about it some and realized there may be some residual charge in the phone, and my waiting period is to allow the charge to drain. To test this theory, I powered the phone down and then tried to restart - nada. Pulled and reset the battery - nada. Pulled the battery, shorted out all four pins that would make contact with the battery, reinstalled battery, and it powered right up. I have not been able to successfully repeat a fast restart when shorting out all four pins. Pulling the battery and waiting 30-60 mins still works.
Incidently about the same time, my screen has stopped auto rotating (and yes it is set to do so).

What are you doing exactly to short out the battery?
galaxy nexus reboot
my galaxy nexus is about 1 year old now and this is the first time that i've encountered a problem with it. It suddenly restarted, and will take about 5-7minutes before it opens, it will be open up to the "X" logo and when it reaches the normal screen it will restart again. I don't know whats wrong with it. please help/

You saved my Galaxy Nexus
Similar problem + water
Ok, so I have a similar situation I believe. My phone took a swim. I left it off and riced it. Later on after I believed it to be dry enough, i turned it on. (wow it freaking worked) After a few seconds of using the device checking screen the phone snapped off and went into a reboot. I waited until it came back and i shut it down and thought I'd let it go over night. I plugged it in and let it charge (charge icon was displaying). Everything looked good.
Fast forward. Morning time. I go to turn the phone on. Nothing.
This time the phone won't boot. Instead all i see is the white battery icon show up indicating the battery is 100%. When i plug it in to the charger i get the battery with the charging bolt, then it shows the normal battery indicator light. After that, I get nothing.
I tried the method I saw above. remove power, remove battery, apply usb power, insert battery, press power. Sadly it didn't work.
Anyone have any other ideas as to what might be going on?
Sorry if this question's been answered in another thread, I tried searching and couldn't find any question that exactly matched mine, or any response that solved the issue.
I purchased a used, unlocked Galaxy Nexus from ebay around a month or two ago, in near perfect condition -- this has been the first time I've had any problems with it. It's probably not applicable, but after the release of the dev preview for Ubuntu phone OS I rooted the phone and reinstalled the factory image "takju 4.2.2 (JDQ39)".
Anyway, a few hours ago I accidentally bumped my phone off of a counter in the kitchen onto the tile floor. I picked it up and looked it over, and noticed no visible damage whatsoever, although the plastic cover had been partially dislodged; however, the phone's screen was dark, and the phone was unresponsive. I took out the battery and replaced it, then held down the power button. The phone vibrated once, like it normally did when booting up, but the screen remained black and the phone unresponsive unless I removed and reinserted the cover again.
I've tried charging it, plugging it into my pc, removing both the battery pack and the SD card, taking the battery out and rebooting it while holding both power buttons down, but I still get no response (and my computer doesn't recognize the phone when I plug it in). After reading a post where someone had success reconnecting the display, I unscrewed and removed the casing, then disconnected and reconnected the display from the motherboard -- still nothing.
Is there anything else I can do, or is my phone beyond repair?
Did you check the other connections while you had the phone apart?

I opened it up again and took pictures, but I'm not very knowledgeable about this sort of thing, so I can't tell if anything's wrong or not. Should I remove the motherboard to get a better look at the display?
You're talking about the back cover which became dislodged upon impact? I'd say you're lucky that the phone still gives that vibrate. But it seems there are so many things that could go wrong from an impact. Do you have fastboot? [I know you said you tried holding down both volume buttons and power, but try pressing them first then tapping power.] If you don't have fastboot, then your only options would be omapflash and odin. If these do not work, it's gonna be hardware. Maybe the display is gone, if you get the vibrate but see nothing..
Hi,
a couple of days ago my ASUS ZenFone 2 (Z00AD, ZE551ML, 4 GB RAM, 8 GB ROM, 1.8 GHz) started behaving very erratically on its own. It's not been rooted nor has been the bootloader/recovery modified.
OS version was the latest: WW-4.21.40.352.
Before it all happened, I cracked my screen and replaced it.
The phone worked perfecty (aside from the screen not being original (occasional flicker)) for a week, after which I started to lose signal in the SIM1 slot. It took me 6 weeks to realize, it might've been the antenna cable. I disassembled the phone again and inserted the cable again. It then worked perfectly for a couple of days.
Then it looked like it was damaged by water, which of course was not the case.
It started with continuous vibration and black screen, and only a forced shutdown (by holding the power button for a couple of seconds) helped. Then, it started to restart on its own and lose signal. Then the speaker stopped working, until poking its area. And at last, the phone thouht I have View Flip Cover on and all I could do was to force shutdown.
Then the phone didn't wan't to turn on at all. It didn't even charge and was not being detected by the computer.
I then read, one has to pull the battery cable twice and it did help.
The phone worked fine for a day, until it started going into black screen/constant vibration state, in which only a forced shutdown helped.
I followed a guide to redo hard brick and it's helped for a while, but now the phone constantly goes into black screen/constant vibration state at random, the same hapenning sometimes when charging while turned off or when choosing any option in the stock bootloader. It also doesn't boot completely (the ASUS logo shows up much later) and the WLAN doesn't work.
I followed the unbrick guide correctly. I read up, the mainboard might be corrupt.
What do you suggest? I of course, lost my guarantee the moment I cracked my screen.
Many thanks in advance.
Check the connection of the flex cable on the daughter board. Pretty sure there is loose connection.
