SOLVED!!! [Q] Help! Nexus S won't turn on!!! :(

Hi everyone.
Last night I went to bed and as usual I check my Nexus S battery.
It indicated me very low battery, and turn it off.
So far, no problem, i thought, well there isn't enough battery to turn on the phone. I connected the cellphone to the wall charger and went to sleep.
Today i woke up and try it to turn it on, the screens just flashes and nothing happens.... Removed battery, try it again, the same.
Try 100 times that, and there was one time a Warning of Bootloader came up. Don't know what i did different thought, but now i can't get the same result.
Actually now the screen doesn't even flashes when i press the power button.
The battery seems to be charged, i tested with a LED. My wall charger is also working cause it's able to charge my old phone.
And now to get things even worse, as i bought it in asia, i don't have warranty, and the gran finale, Nexus S is not been sold in Brazil due to some regulatory issues, so Samsung said it they can't help me with an imported product.
The Cellphone is brand new, doesn't have not even ONE month of use.
It's not rotted, and it was in the latest android firm.
Does anyone have any idea what can i do????
The phone doesn't respond to anything .
Tnks a lot in advance.
PROBLEM SOLVED!!! SEE THE LAST THREAD. BR!

Is it showing full bars when you connect the charger and press the volume button?

dude, i think there is something wrong with our country. take a look at this thread: http://forum.xda-developers.com/showthread.php?t=1111761
i think you tried everything possible, can't see what else you could do. Looks like a hardware issue..
if i were you, i'd claim for warranty, even if you bought in hk, it has warranty, of course you will lose shipping cost, but, it's better than lose the phone! =o]
good luck!

GchildT: Nothing happens when i connect the charger to the cellphone.
Already tried the hard reset (volumn up + power button) nothing happens
thiagodark: Tell me about it, i read this thread ealier this morning, actually i send it a private message asking him if he solve his problem... samsung is really disappoint me.
The thing i found most said is that the phone is bran new! Not a month year old.
And i didn't do anything, not even rotted, dropped, anything!

PROBLEM SOOOOOOOOOOOLVED!!!
The problem was that there was a little tiny piece of plastic dirt in the usb male plug in the phone! And that piece was able to make a faulty contact with the charger, the phone battery was dead as hell.
Can you believe that?????
I almost sent my phone across the world in order to use the warranty.
Now I'm back with my cellphone up , happy as hell!
Tnks a lot, and remenber to always clean everything before use more drastic measures.

[Q] ***HELP*** Transformer won't turn on.

My transformer will not turn on. I used it a couple days ago but don't remember if I fell asleep or powered down. I went to turn back on this morning but there is no response. If I plug in the charger I can see the light come on. Also if I hold the power button it will give a quick vibrate after about 10 seconds. Has anyone else had this problem?
Its rooted and unlocked. Any help is appreciated, thanks in advance for your time.
I forgot to mention that there is nothing being displayed on the screen at anytime whatsoever...

Try cold booting it? Turn it off and then turn it on while holding the volume down button.
Try connecting it to your laptop, see if detects it???
Maybe its a software app thing?

Already tried both. Problem is, is that there is no way to see if the device is even powered on... The battery meter on the screen doesn't even show up when its plugged in/charging...

Wow....that sucks.
If your computer doesnt detect it, then idk what you could do.... cuz if it did, then you could try to use adb to try and restarting t.
It sucks that its unlocked or i would have said to just contact asus to get it replaced.
Other than that, its hard to say...sorry man.

Mine did the same thing today. Hold down Power, Volume Down, and Volume Up for a few seconds to force a reboot. It got mine going.

Tried hitting the reset? It's in the little pinhole above the hdmi.

Held down power, volume down, and volume up at the same time.
Then tried the paper clip in the reset button by the hdmi input.
Then I tried both ideas again with the charger plugged in....
Frustrating. Unless someone has anymore ideas I may just try and send it in. Hopefully they cant tell if its been unlocked or not because nothing is being displayed..

You can't send to ASUS when you use unlock tool they get your S/N and save it in case something like this happens. The only way I can see around this would be if you bought it at a Best Buy. They maintain 1 year manufacturer warranties if you bought from them so you could feasibly take to geek squad/Customer service and say it just stopped working. They wouldn't have record that you unlocked the tab. You would most likely need the receipt or some confirmation you bought it there though. Good luck.

Sorry friend, seems like you are in real trouble. I had a very similar problem, my only solution was to exchange it:
http://forum.xda-developers.com/showthread.php?t=2203565
As you have unlocked yours, the warranty is no longer valid, and although Asus will fix it, you will have to pay to get it done. Since I'm on my second TF, and it even has had a problem that nearly bricked it, I am simply afraid to unlock it while still within the warranty period.

Might get lucky and see something with it connected to the HDMI port.

They did with my TF201 and this guys TF700 just a month ago http://forum.xda-developers.com/showthread.php?t=2240970

They took back my TF201 in August last year. I was told by BB it was done under the manufacturers warranty. It really does depend on who you talk to and how you approach them with the problem. Several people had to try different BB stores until they found that one person working there that either knew HOW to do it or was willing to take it back.

I had the same problem. Tried all the ideas mentioned above. I then put it on the charger for a day and afterwards it just booted like nothing had happened.
(mine is not rooted or unlocked)

TF201 is a different tab and basically BB and asus came to an agreement to take them back. The guy in your link got lucky. Probably only got a trade because of the extreme nature of the defect. Fact is you cannot just go into BB and get a new tablet under mfg warranty.

Exactly.
Now for the good news. My tablet came back to life last night after 3 weeks of trying. It was totally dead and wouldn't even vibrate anymore. plugged it in and it actually tried to boot right away but then turned off. Let it charge for a few and tried again and it booted no problem. Battery % is now showing accurately and it has now been running fine for 12 hours.
My problem is I went out and got an HP envy x2 (win8) tab on saturday. Now to decide which to keep... I love the envy but the new quad cores are coming out this fall which should really make it a versatile little laptop. Just don't know if I can live with android now that I have a taste of full win 8.

Any updates? My TF700 stopped turning on as well. Same recovery efforts, now waiting on the battery to drain. I unlocked/rooted for cleanrom (faster/better). Worked fantastic till last thursday and it refused to turn on in my college class. This could signal my exit from Android even though I have a lot of money invested in apps.

I recieved my tablet back from asus. Appears they swapped motherboards and i have a stock tablet again. No charges to me. Took about two weeks. Of course i will try and root/unlock again.

Good to hear. Aside from the snappier response of cleanrom my biggest issue with the asus firmware was the waste of screen space on the home screen. It had like a 1" border all the way around that you can't put an icon in and that annoyed me the most of all. Been waiting the battery to go completely dead before I send it in just hoping that fixes it.

[Q] Phone powers off and doesn't come back on..

weird issue in that for the past two days the phone will not power on. I can hit the power button which "does not appear to be stuck" and it will briefly turn on getting to 1st splash screen before going black and not coming back on. Can't get into anything. While ago messing with it I had it fully boot but when the screen timed out I hit the power button any it wasn't on anymore. I even got it to turn on for the drive home for about an hr and was able to listen to pandora. I have unlimited data so I didn't want to get a new phone. So I looked online and saw someone had a brand new s4 for 320.00 bucks.. which I think I can keep my data if I buy a phone elsewhere correct? I also looked at replacing the motherboard for my s3 which was 90 bucks. Need some assistance either making my s3 work or ideas of what phone to get under 300.00

also.. When I plug it in while it is off it doesn't appear to be charging.. Maybe it is the battery? Maybe it is the charging port?

I think you should try another battery first. However, I do have some questions. Is you charging port loose on your phone? Is your phone still under warranty through your carrier? I recently had issues with my S3 draining really bad. I'd plug it into the charger and it would definitely act like it was charging up but in all reality the battery was draining like a sieve. I called Verizon Wireless and ended up getting a new phone as a warranty replacement. It's working fine now. *knock on wood*

the light doesn't come on when charging like before. the port is not loose. I took the phone apart to see if there was something damaged or loose inside and everything seemed fine. I doubt the phone is under warranty. I just purchased a new battery for 16 bucks.. hope it works. I will update this thread on thursday once I get the battery in.

Sounds similar to what I ran into with my charging port going bad, currently it will only work with the stock charging cable but I have purchased a wireless charging battery cover and use that for 90% of my charging.

If you are gonna get an S4, make absolutely SURE it is an MDK build!! Anything after that has a locked bootloader! Ah hem...mine is MDK and comes with a mophie case...and glass screen protector... just saying.

the battery didn't fix the problem. I guess I will have to replace the motherboard. I bought the s4 today for 275. but as caleb stated it is locked.. oh well.. I think I can still root it. I am hoping I can replace the board no problems and atleast sell this thing for 175. Anyone have much luck with these boards? http://www.ebay.com/itm/OEM-Samsung...05&prg=10335&rk=1&rkt=6&sd=271467013367&rt=nc

I am googling this problem for a friend with a stock verizon S3 - there are TONS of people who can't charge once they're on KitKat. Is that the case with you? It seems to be a software, not hardware, issue.
From the sounds of things, don't expect a new board to fix it.

Nope. I never updated.

Also, the charging part is not the only problem. I had a full battery but couldn't get the phone to stay on. Eventually I couldn't even turn it on at all. Just died.

[Q] LG G2 will not power on, seemingly no reason

Here is what happened exactly:
So the phone is sitting on my windowsill so i can get service and receive texts messages. i get a text so i walk over, pick up my phone, unlock it, and i pressed on the textbox to start typing my reply message. as soon as i press the text box my phone freezes, and thinking its no big deal i hold down the power button to turn off my phone (took about 10 seconds to power off). Now my G2 will not do anything at all, wont power on, wont charge, the red light doesn't even come on with the charger plugged in.
Things I've tried:
holding power/power+down/power+up for 2 minutes+
disconnecting the battery for 5 minutes and trying ^ again
disconnecting every component and reconnecting then trying ^^ again.
disconnecting battery, plugging in charger
disconnecting battery, plugging in charger, then reconnecting battery with charger still attached
charging with lg charger for 12 hours
additional details that may be useful:
at&t D800
rooted
cwm recovery
optimus g3 custom ROM
literally never have had an issue with this phone before
a new battery is on its way in case that is the issue

Scratch that, i actually canceled the purchase of the new battery because i think i may need a new mobo instead. I'm not gonna buy anything until i get a second opinion at least.

sorry about the 3rd post in a row
I've ordered a new motherboard that has arrived today in the mail. after i get that in my old phone ill update the thread again.
I have to say though, i am extremely surprised and irritated by the absolute lack of support I've received from this site. i would always come here to find answers in other threads and the community seemed pretty awesome, so its pretty unfortunate that i haven't gotten even a single reply. i guess people only want to help others when they already no the answer...

Have you found a solution to this? My phone did the exact same thing yours did last Friday. I tried several button combos and the only thing that gave me some hope was resetting (power + vol. down). I was able to get the LG splash, then the ATT splash and jingle with the LED lights changing colors, but that was it, went back to dead. I'm debating ordering a battery and some tools to try and get this working again.

Yeah, so i got the mobo in my phone and it turned on and everything was working again! however the mobo i bought had a broken battery connection so i could only use it if it was on the charger so i had to send it back. but replacing my motherboard will fix my issue.
as for yours i have no idea, if it wont turn on even with the charger plugged in then replacing your mobo may be a solution.
i still think its pathetic that no one with real experience has replied to this thread, i guess you cant believe what your told about this place unless your question is easy to answer.

i got it on eBay, the original price was like $120 but i put in an offer of $75 and they took it. when you buy it make sure you compare the pictures on the posting to your actual Mobo.
All that you will need for the switch is a credit card, a knife, an extremely tiny screw driver, and some double sided tape(the tape is optional).
as you can see in my picture, the board i bought is on the right and the old one is on the left. you have to watch for stuff like that when buying a part like this.
i think I'm about to buy a D800 G2 with a busted screen for $40 in the next hour, if i get it ill let you know how it goes.

Success!!!
Alright so yesterday i did buy that busted G2 and when i met up with the kid i made sure everything worked before i bought it. i got back to work and made the switch(i was going slow and i was debating on swapping the charging component, took about 35 minutes).
I did not wanna put my Sim in the phone until after i had downloaded all my apps and configured all of my settings the way i like them, so about 6 hours later i get a chance to make the final switch over. when i did put in my SIM everything APPEARED to work fine, but when i left my home i realized that my data was not sending or receiving anything at all? i went to the grocery store and bought a glasses repair kit for the screwdriver inside and opened the phone back up, everything appeared to be connected properly.
I left and called AT&T customer support and this guy helped me fix the issue, apparently their system though i was still using the temp iPhone 4 i had. after he switched the old IMEI number to my new Mobo's IMEI, i restarted my phone and it worked perfectly! i highly recommend taking this route if you can get a new board for less than a new G2 costs.
The Mobo i got off the kid is legit too, i guess he bought it only a month or two ago because it has some features i did not have like the knock code. i also got it rooted and flashed TWRP, not sure if ill flash a G3 ROM or leave it like it is.

i can get phone into odin mode and try flashing stock Android 11 which i have on pc
BUT im afraid my phone might die or switch off while flashing stock rom.i asked a repair guy he says problem can be with motherboard .
im not sure to try flashing it

i managed to enter odin mod3 blindly with keys
flashed Android 11 stock firmware it was success
the phone gets On
connects to pc. connects via dex mode to tv also.
no more random reboots
but still black screen display not getting
awake only can access via dex mode or mirror mode

After around 24 hours ...
of soft reseting , stock firmware 11 install . and slapping and tapping and massaging, connecting to tv via hdmi in mirror and dex mode. my phone was in black screen of death.
everything was working. but no display. i can say that becauee in dex mode i used phome dsplay touchscreen and even spen was Workiing but no display.
last thing i was doing when display came back to life after tapping slapping soft reboots i was opening camera app and closimg and opening it multiple times. and i saw at same time display gettimg back.

I have exactly the same issue. I was typing on whatsapp when suddenly screen get black. Notifications were ok, voice commands too. Touchscreen ok, I could use it normally when using my TV as screen with HDMI cable or with my notebook, when connected to windows or even Dex.
I already flashed fresh stock Android R rom and my display is still dead.
Tried to tap, slap, shake (I can her some noise next to camera module when shaking). I'm draining battery now with some apps that also vibrate phone. Display is still dead.
I live in Manaus/Brazil and repair centers are not working until March 23 because of Sars-CoV2. And my knox is tripped. It would cost a lot If I have to replace display or even the phone, since they probably will say it's no longer covered by warranty.
Were tou opening and closing the camera while mirroring screen? or on blind?
It seems in your case, the display went back to normal as strange as it turned off.
Could you please share the mentioned youtube video?
Hope I have that lucky as well.

I have exactly the same issue. I was typing on whatsapp when suddenly screen get black. Notifications were ok, voice commands too. Touchscreen ok, I could use it normally when using my TV as screen with HDMI cable or with my notebook, when connected to windows or even Dex.
I already flashed fresh stock Android R rom and my display is still dead.
Tried to tap, slap, shake (I can her some noise next to camera module when shaking). I'm draining battery now with some apps that also vibrate phone. Display is still dead.
I live in Manaus/Brazil and repair centers are not working until March 23 because of Sars-CoV2. And my knox is tripped. It would cost a lot If I have to replace display or even the phone, since they probably will say it's no longer covered by warranty.
Were tou opening and closing the camera while mirroring screen? or on blind?
It seems in your case, the display went back to normal as strange as it turned off.
Could you please share the mentioned youtube video?
Hope I have that lucky as well.

Sorry for the late reply mate. The Scenario when display got back alive was.
1. My phone was connected via HDMI to TV in Mirror mode (Not Dex Mode). I also had mouse and a keypad connected since i am using Samsung Dex pad which came with my old note 9
I have from day 1have doubts about the stock camera app on my Note 20 Ultra. The app misbehaved from ranging to camera fail, and force closes on Android 10. That why i did below next
2. I forced close camera app , cleared its data and then while watching on Tv
i placed my finger on Camera icon and repeated opened it and closed it with back key.
since the display on phone was off so i used Tv for help
BUT physically doing the action on phone with fingers not with mouse on screen via mirroring
3. while i was repeatedly opening and closing app by touching the display with finger suddenly i saw camera app asking me for location tags pop up on display and from that time onward there has been no issue and the display is working as nothing wrong happened.
I wish and hope you have resolved issue by now. Please do share your experience for others . since when i had this issue, i found very less information about it. but i saw around 15 to 20 users having such issues especially with Note 20.
Conclusion what i have understood is either its some issue with Note 20 Ultras Camera Firmware or THe Electjet 45W Charger the culprit which i bought for my Tab S7 and was using to also charge my Note 20 Ultra. I have stopped using this charger for my phone and tab and since that day only using 25W OEM charger which came with the phone. I have now this 45w Electjet charger connected via Samsung dexpad which caps its charging speed to 15W.
Here is the link of the video. and i tried all things mentioned and then after exact 24 hours
the display came alive back when doing activities i mentioned above. and i have no link with the guy or channel who posted this video. I was just trying everything to bring life to my dead display .
PS: i had only 5 percent belief in this video . i dont know what worked
i had prepared my mind for the300$ plus panel display replacement.
i just read two recent more comments which state they got their phone working back.
Do read the comments posted as there might be some more clarity of things to try.
(Please Apply reasonable pressure on screen when trying these actions as you might break the Display)

Worked! Slapping it around and massaging it with reboot. Who knew Smack My ***** up! - The Prodigy was referring to modern phone fix'n.

I'm here literally in tears, my keyboard wet typing this because the video actual "Fixed" my phone. I don't know if its a long term fix or just temporary but after 24hrs of a black screen its good to have back a working $1400 phone.
So if this happened to you, dont be skeptical and just try the steps. Last resort is to bring it to a technician or Samsung but definitely try this before.

It just came back on this morning. All I did was let the battery fully drain.
