What kind of puter? You got the right samsung drivers?

I tried on my laptop (Mac) and desktop (windows) and yes they have the right drivers
Sent from my Galaxy Nexus using XDA

Well your mac laptop won't need drivers. If it's plugged in and your phone has the settings box checked for "MTP" then it'll be recognized. Did you download Android File Transfer? You'll need it to transfer files.

Is USB debugging checked? If so, uncheck it and try to install the drivers again. If you can't, shoot me your Gmail and I'll help you through G Talk.

Custom kernel? Make sure USB fast charge is off.

Ok! I tried the new cable that came with the replacement and it works just fine... its weird that the cable I have is not working anymore..

"Made in Korea" means it was manufactured by Samsung directly and not outsourced to some factory in China.
If you're unhappy with the signal drops you can try to get another replacement, or look at the threads here on signal drops for solutions

Yeah! I'm looking for ways to fix it.. but the one I had was made in china and was brilliant no drops nor anything. I curse the day I dropped and cracked the screen.. do you think I can just go to the Verizon store and ask them for a replacement

If you're within the return period, they will replace your device no questions asked. If you're over it, it would depend on the store you go to but more likely than not you have a good chance.
Just make sure you're stock and not rooted

I called yesterday and after a couple of minutes well an hour to be exactly they're going to send me a new device. That's what she said. But since today is 4th of July the phone should be here by tomorrow..

I think CM 10.1 killed my GS-III

Since December I've been running CM10 on my GS-III with little to no issues. I flash CM 10.1 mid January and even though it was an unstable nightly it was very stable.
Flashing the nightlies as they became available with no issues at all.
Then today my phone starts slowing down and froze up.
Keep in mind that I hadn't flashed a nightly in like a day or 2 do I had been using the past nightly as a daily driver.
When my phone decided to freeze I rebooted it and it booted just fine.
About 2 minutes in the screen goes black. Holding the power button it's unresponsive.
Now my phone is completely unresponsive to all button presses. I've tried the 3 button combos for recovery and download mode with no luck. I've even held the buttons for a full minute but nothing is working.
Is my phone dead or is there a possibility of resurrecting it?

Are you positive the battery hasn't died. That would be the first thing I would check. Even if it showed it was charging doesn't mean the battery is good. I'm not trying to be insulting either by asking this. I'm a equipment tech at a large semiconductor company and you wouldn't believe the number of times the fix was as simple as turning a breaker back on when another tech wanted to replace something major. #1 rule of troubleshooting: Is there power. #2 rule: Double check rule #1. Sounds silly, but it is the easiest thing to overlook. Good luck and I hope it's as simple as a battery.

No you're not insulting by asking that. I use to record music and when something wasn't wasn't working that's the first thing we asked and re asked.
Unfortunately I do believe I checked that out. When I plug in a charger it doesn't even show me a battery charging logo.
I have noticed that when I pull out the battery and connect the charger the led turns red.
I'll see if i can't swap batteries with one of my friends and see if that helps.

Can adb on your pc detect your phone by any chance ? I do not want to scare you but hopefully your not having a motherboard failure or a sudden death :/

Well unfortunately there's no response from adb or phone.
However the computer does make a usb device connected sound.
Not sure if that's just a standard sound from the computer or if the phone is triggering it.

I have tried the 3 button combos for T-Mobiles variant of the GS-III with no luck either.... I even tried making a jig and didn't have much luck....
Next step is to buy a jig and see if that works
Thankfully I got a replacement GS-III from insurance. So I'm content... Also since I get to keep the other GS-III as well it feels even nicer.

A usb jig should do it most of the time it do work and if it doesn't oh well you could sell it out for parts i guess ?

You would probably make most of your back if you sold it for spare parts and may only have to pay $50 for a replacement. Good luck!

I'm not sure I understand how a jig is going to help him when the phone won't turn on.
I would try another battery first. You said you were going to try this but I don't see where you confirmed that it wasn't the issue.

Hmm you could have ran into that now infamous mb crash and burn error although I'm not sure how since you were running aosp. Anyone else want to chime in?

If the battery truly died plugging it in won't be any help
Try another battery, I'm betting that's the issue. T-Mobile will have one or two on hand in store so you can try

Hopefully I will be able to get my hands on a spare battery to test this with as soon as I'm off work.

Yeah first of lets make sure its not the battery and the jig forces the phone to boot into download mode if im not mistaken.. It is intended for users having similar issues / unresponsive devices...

Well unfortunately the spare battery i used on my phone was no good in getting the phone to respond.
Now my next step is to attempt to hope that the jig will do something for my phone.
If not i guess that i will have a nice paper weight of luxury lol
Either that or i can sell it to someone.
So far those are the only options that i think i have at the moment.

Flash STOCK or different ROM (Don't forget kernel too) think the issue is with the Cyanogenmod, mine did something similar, when screen went dark it took literally 5-10 Power button presses to wake the phone up, sometimes it wouldn't respond, other soft keys only would light up, Make backup, Wipe, install, check everything, that what I would do

The phone is dead. My friend's gs3 died suddenly one day while I just happen to be using it. I plugged in an otg plug and few minutes later the screen just went black. I was sure it was dead when I plug in a charger and there was no sign of life from the phone.
I don't know if you have to pay a deductible but Samsung is supposedly replacing galaxy s3 for free because there is a known defect which cause the motherboard to go bad. My friend's was a Verizon model and they just replaced it free.

[Q] SGH-I747 Completely dead

Hi,
I recently rooted my phone (SGH-I747) this was two weeks ago. Everything was good no problem nothing at all. This morning I restart my phone and it will not start again. The battery was full charge and I tried other battery and does not work. There is no light when I try to charge it and there is no sign of life nothing at all. I tried to get into download mode but I could not. My question is there any hope that I can get my phone back I am really frustrating. :crying:

Try pulling the battery for 30 seconds. Reinsert the battery and see if your phone can boot.

My condolences. Same thing happened to my phone today. I called up AT&T, and they referred me to a local AT&T Repair Facility. They tried what they could, but in the end, they swapped my phone out. I ended up losing all my stuff that wasn't backed up in the cloud. Not a lot, and mostly all replaceable... but annoying just the same.

lol. I had an iPhone since the first gen came out. switched to this device and will never look back.
FYI: I've had defective iphones too. There will always be a defective device from someone. no mfg is perfect. Hardware fails, it isn't anyone's fault. Its why there are return policies and warranties. I've taken my iphones for replacements and I've taken my android phones in for replacements.
P.S. If you had more than one bad experience with the same product I would understand your frustration. However, switching to a less powerful phone because of one bad experience is absurd.

My problems started from the day one. First time it did not accept my micro sim card and they replaced my phone and after one week the charger did not work and after one month they sent me a new one. now my phone is dead. Samsung customer service is the worse in this country I really had to fight with them just to send me a new charger. I will see what will happen tomorrow when I tell them that my phone is completely dead.

it's dead Jim!

I will try to make this as short as possible. I got my vzw galaxy nexus used on eBay 3 months ago. I loved it like it was my second child. A week ago I noticed the radio was not showing a signal or a very weak one, sometimes but it always worked. Until last night, It wouldn't register a signal so I rebooted it. It started to boot loop, never getting past the nexus logo. It was unlocked, rooted, but running stock jdq39. I left the battery out for an hour and it did boot to the lock screen. I would unlock then it would reboot again by itself. I then went down the road of trying to flash stock images, radios, and even cm10. All the stock images failed on flashing CDMA-radio. Cm10 came up but it started boot looping again, baseband was unknown as well as other info under status. As a last resort I tried to Odin 4.0.2 it failed at the very end trying to write (wait for it) CDMA-radio. Now it only boots to a yellow triangle with a phone and computer image on either side. I an not missing anything stupid right? The CDMA radio must be toast.

Probably. Fastboot also fails?
a maguro wrote this.

It certainly sounds like a part of the hardware in the radio has been going bad. Is there any warranty left on it? Not sure if they're transferable since you bought it on eBay, but it's worth a shot to at least ask, either at your store or Samsung. The only other random things you might try is taking the LTE sim out and if you have access a different battery? Since it's failing on CDMA, the sim shouldn't have any effect, but since it's dead, it's worth a shot. Same for the battery. But yeah, sounds dead.

Yeah I can't even get into the boot loader anymore. So adb and fast boot don't work, but Odin still connects and can flash, just gets stuck at the cdma-radio.

I tried flashing with and without the sim. I just got the extended battery too, and also tried with both. Will check on warranty. If not it will be sold for parts on eBay. Case and screen are in perfect shape.

Thanks! It was absolutely the cdma radio that died. The replacement came with CM10.1 RC4 but decided to flash it back to jdq39 stock. It flashed without problem using the same USB cable, computer and drivers. It seemed like hours when I flashed the cdma radio but in reality it only took a few minutes, but was very relived when it finished successfully. I figure I am just going to keep the other parts in case I need them.

Hard-Brick?

I'm just wondering if someone could give me insight. Earlier today, I was installing xposed settings on Android 4.4 Kitkat(ROM) on AT&t I747U. After doing so, I hit reboot and it hard-bricked my phone(I was trying to install the experimental features for greenify. I know the difference between soft/hard and this is definitely a hard brick. Phone will not power on at all. I plugged in into my computer, and my PC makes that beep sound when you connect a device to it just will not power on to any menu.
Anyways, I know that I have to have it JTAGed. I was wondering if anyone has ever used Mobiletechvideos.com for their JTAG service? I'm skeptical sending my phone off, but if it will save it, then by all means I'll do it. How successful is the JTAG service? If anyone could help me out, it would be appreciated
-Thanks, a bricked Galaxy S3 user.

They do a great job I hard bricked my phone and sent it in. Got it back within the same week
