NS4G dead. No response. - Nexus S Q&A, Help & Troubleshooting

My nexus s will not turn on at all. The power button had previously gotten stuck and I was able to fix it by taking the phone apart. He was removing and inserting the battery and the phone would automatically turn on using this method. Now the phone wont turn on, wont charge, and is not recognized. The only way I can get anything to happen is if I unplug the chip that says sandisk. The phone obviously doesn't boot, but pressing the power button actually gets me to the Google screen. Any advice? Also, if the memory chip was the problem, is there anyone that sells them? I can't seem to find the part in stock anywhere.

[Q] Phone won't stay in download mode?

I'm having some weird problems getting the phone into download mode. If I hold down voldown + power + trackball, the phone goes into download mode and is recognized, but then leaves download mode about 5 seconds later. The screen goes black and the charging screen turns on for a few seconds and then also goes black. If I just plug in the phone to charge, the charging screen turns on for a few seconds and then cycles with a black screen.
Is there something up with the charging circuitry? Is it possible to get the phone to stay in download mode?
Try doing the forced download mode method
Are you talking about the volume down + trackpad? Same thing happens, download mode screen flashes for ~5 seconds, phone turns off, starts flashing charging screen.
I also have a download mode jig, but that isn't working either.
Also, new development: the phone won't even turn on now when I hold down the power button. Bad battery?
No he means pull battery, connect usb, hold power, volume up, volume down, camera, and tackpad and insert battery. It should FORCE the phone into download mode.

That works, but I still get kicked out of DL mode after about 5 seconds. The issue was never getting into download mode--all button combinations work for that--but the problem is I get kicked out of it after a few seconds.
Hmmmm. I think its probably a bad battery.

Alright. I'll definitely check that out and get a new battery.
Got the battery today. Unfortunately, still the same problem! The Sidekick boot screen now displays in place of the battery charging screen, but I still get kicked out after 5 seconds.
Damn, well the only thing I can think is a problem with the board not receiving enough power. But I don't know, maybe someone else can help you better.

Another thread reminded me...
Fixed the problem! Seemed to be a ribbon cable or some sort of loose connection. I opened up the phone (all the way), removed the RF shield, unplugged all the ribbon/connector cables (minus the one for the camera) and removed the whole board from the phone case. Checked the connections, put everything back together snugly. It now works like a charm.
same problem
would you make a tutorial on how to do this ?

Yeah i had the same problem iv been trying to go into recovery mode and safe mode. I cant do it im having the same exact problem. I get kicked out every 5 seconds but Redct has a point. There may not be enough power going to the phone. I may attempt at taking the phone apart extremely carefully. If this works ill post then its a manufacture problem for not assembling the phone right or not finding out that people do lots of things with their phone and the phones is just a bunch of computer componets wraped around a piece of plastic. Better quality phones must be sturdy.
So I attempted to take apart the phone and put everything back together and successfully booted. I it booted into the Android OS but then for some reason crashed and entered the boot loop again god this is irritating

Same Problem
I am having the same problem. I took the phone apart, but I couldn't figure out how to get the circuit boards out to unplug the ribbon wires, can you tell me what to do? I had the same problems a few weeks back, but it was staying in download mode then, but now it won't stay in download mode for more than 5 seconds. I got a new phone because of it(LG Optimus). I would really like to get my Sidekick going again though!
Try using heimdal n enable flash bootloaders n hold the volume keys

I'm attempting this fix. Got arround taking out the board and just need some help with what to do with the RF. I can't simply take it out and put it back, my guess. Any help is appreaciated. Like what kind of tool would I need for that? Thanks!
The RF shield or the RF 5000? I'm confused.
BTW... If anyone needs help with how to dismantle the phone, follow this thread. It can be found in General section.
I know this forum is ancient, but I'm working on an E-Bay phone with this exact issue. I found the following thread the most useful and informative on the problem:

Help.. Phone is dead

Everythings been running fine on it since yesterday. Earlier, I turned on face recognition lock just to see how well it worked. First try was fine. Been sitting in my holster for a while and just pulled it out to use it. The lock screen was totally blank. I could pull my notification bar down but if I clicked on anything, ie, settings, nothing would happen. Volume button worked but none of the capacitive ones did anything. Tried to reboot, nothing. Held the power button to force a restart, it restarted but still nothing. Held it again for another restart and after the message, it turned off but instead of rebooting, nothing happened. I Power button does nothing. Plugging it in, no light comes on. It's totally dead. Any ideas at all? I sure hope this device is not this temperamental. With my good ole inspire, I would just pull the battery. I have no idea what to do with this one with a non removable battery. Please help.

[Q] Ultra Sensitive Power Button

i changed the title since that is not the issue any more. i re-melted the solder on the power button and it stoped the loops but now it just made it super ultra sensitive like its a touch screen button. any ideas?
so my phone just randomly shut off one night and it automatically turns on when i have my battery in and it just stays on the samsung logo for about 2-5 second and sometimes the touch key lights turn on but just turns back off and does the same. when i try to boot into download mode it doesnt go into it, it just show the image of the batter loading with the loading circle for about 5 second then shuts off. The phone its rooted but running stock. any help with be greatly appreciated!
If I searched for something like this I'd probably find info on the power button being stuck.

Already tried that solution, im slowly starting to think it is a hardware issues. there is no water damage at all.
Hey.
So I have the EXACT same problem...
Phone was on CM10 Jellybean (no OC). Randomly shut off and started to bootloop. Phone will start bootloop when battery is plugged in.
1) Put in battery while holding vol+/-
2) Put in battery while holding power vol+/-
3) Put in battery while holding vol+/- and USB plugged in (I believe this is the correct method of getting download mode)
4) Put in battery while holding vol+/- and USB Jig plugged in
5) Put in battery while USB jig plugged in.
I am all out of ideas. When there is a USB jig, the phone DOES get into download mode, only to immedialtly bootloop back into download mode.
Did you Odin or Heimdall back to stock (since you are in download) and see if it still loops?

Ehh i have other phones but i like to learn since i work for a electronic repair shop and this isnt the first time i ran into the bootloop issues but now i have some base on how to fix it... not not the ultra sensitive button part xD
Do you remember what the power button looked like? I think I am going to pay for this service. People have said they are reliable.

[Q] Maybe bricked? Idk? Help please

Hey everyone
Verizon SGS3
Earlier today, phone shut off randomly during use.
Phone won't power on without a battery pull.
Trying to boot normally: can see "samsung" for a split second, phone shuts off.
Trying to boot to recovery: get to screen where in the top left corner it says "recovery booting...", lasts for a split second, shuts off
Trying to boot so I can use ODIN: before I can even hit volume up to go into download mode, powers down
I was hoping I'd be able to get into recovery and then just do a factory reset, but I'm not given enough time before it powers down.
Is there any way for me to factory reset from pc?
Would this even work?
Any help is appreciated

You aren't bricked, it sounds like either a battery issue or a power button issue. Does it turn on completely when it's plugged in?

It does not turn on completely at all and hasn't for several hours now. The best I can do it get it to begin powering up, into the different modes, and then i get a black dead screen. Even if i try to power back up right after getting the black dead screen, nothing happens at all. I need to do a battery pull to attempt again.
Up until this day I've never had any battery or power button issues

I think it's your power button, if it were hard bricked it wouldn't show anything. Those symptoms sound like the power button is stuck in the on position when you're powering it up.
If you're under warranty send it into Samsung and they'll troubleshoot it.

Do you know if Samsung is going to give me a hard time because it's rooted?
Verizon will for sure. Why dont u find another s3 battery and check it first. If battery is bad it will not turn on regaurdless of whether its plugged in or not. Power goes through the battery.

Phone just randomly died?

I had my phone unlocked and it was sleeping and then when I came to turn it on nothing would happen. It wouldn't even come on when I plug the charger in. I got it to restart by pressing the bottom volume and power button at the same time. Anyone else have this problem?

I didn't understand, you got it to restart? does it work now?
can you see something? maybe try to turn it on, wait a minute and then call it, if you hear something your screen died..
also, try to get in to recovery mode or download mode..
