Maybe damage? As long as it has an imei intact I the About Phone under status you are good to go.

turn the phone of, hold volume down, home button and power it up.
check if its been flashed and what firmware its on. look for water damage, etc etc.

Aside from physical damage, take your sim card with you and take it for a test ride. Surf the net, make a phone call, even to voicemail. And like ready mentioned check to see if the flash counter is tripped although not a failsafe as triangle away will reset it anyway.

Make sure the headset jack works.
I once sold an S2 with a faulty headset jack for $450.
I felt bad but I needed the money.

You checked "yes this is a question" which means it gooooooooes where?

Sent a rooted phone to Carphone Warehouse repair center (D'oh!)

Hi, so I sent my GNex to a Carphone Warehouse repair center. I tracked it today and got the message:
We've tried our very best to repair your device. Unfortunately, due to the nature of the fault on your device we were unable to repair it.
Now I'm just thinking I may have forgotten to unroot and relock the bootloader before I returned the device...
If this is the case, would I be able to unroot and relock, then return it again in order to fix my problem? Or will they keep a record that I returned a rooted device?
Thanks

root, rom, bootloader shouldn't matter unless u fried your chip from oc/uv and left all your settings that way

What was wrong with it?

It really shouldn't matter, but if they want to make a big deal about it; unroot and relock the bootloader and send it in again.
What was wrong with it anyway?

Capasitive leds wont turn on??

Not sure what happen, noticed it a few day ago but didnt give it much thought, but basically the leds for the two capacitive buttons on the bottom wont turn on anymore, I tried going into the settings, changed it from always on to 6 seconds, nothing. I tried rebooting the phone, still nothing. The buttons still respond with no problems but the leds???. Any clue to what could be causing this, I don't have insurance on the phone with sprint so I'm thinking of trying samsung for the warranty claim, not sure how that works.

You can probably get an Advanced Exchange at a corporate Sprint SRC . Cost ya 50 $ but cheaper then a new phone if Samsung cant help ya.

Help screen problems...

Hey all, firstly I'd like to say that I searched everywhere and could not find a solution to my problem.
So anyways I was using the app SleepBot and there is this feature where the app helps
track your movements while you are sleeping through vibrations or something. It for some reason
turns your screen on and I suppose that is the reason this happened to my screen. I've tried a factory
reset by just randomly guesstimating where the buttoms are. But regardless it was determined it isnt
a software problem but possibly a hardware problem? The screen basically appears to be glitching out,
flickering is the images which should be displayed on the screen. In the middle there is this white line
and below it there is a white box about half an inch wide
Has anyone encountered this problem before? Is my phone done?... what steps would I have to take in
order to get a new phone.
Can't post a video atm because I don't have more than 10 posts lols... well hopefully someone can answer my questions
and I'll be able to post
If you have any questions feel free to ask =)

Yes thay sounds like faulty device. You know these things are made to work but things CAN short out break or just flat out die on you for no reason. An app wouldnt do that even after a factory restoration. Your last bet is to odin back to factory image and then if that screen problem persists get it replaced

I don't know what steps need to be taken I have never had to have anything covered by warranty or insurance. Try searching there have been discussions on this forum numerous times about warranties and such.
For your first search. Just search for warranty or insurance

Phone bootlooping, even in download and recovery.

First, before anyone says this is sds/brickbug, it seems to be different. My phone keeps turning off between 2 and 10 seconds after turning on in any mode, normal boot, recovery, or download mode. My first thought was a stuck power button like my friend's S2 had (I fixed his) but after taking it apart and testing the internal switch with a multimeter, the switch doesn't seem to be stuck in the closed position as I see a changing resistance value when the button is pressed. It's also not the battery as I have used external chargers and a battery from a friend's phone. Same issue. I looked into the SDS thread and those all seem to be the phone won't boot at all or can make it into download mode but can't flash, but not constant rebooting like this. I've completely taken the phone apart (up to removing the mainboard) several times and can find nothing wrong with it. I'm inclined to think some sort of hardware issue but haven't found an answer for what. What seems the most telling is that, when it reboots during the boot animation (at a different spot each time) it hangs for a second before turning off, making me think it's some sort of serious hang. I also wonder if it could be the power regulation chip.
Bottom line, I've done some serious research but haven't found anything. I'd be willing to send it to a repair shop like the commonly listed mobiletechvideos.com but I'm not sure a Jtag would fix it if it really is a hardware problem. Any ideas or experience with the issue?

Ah, thanks. I tend to think of the Q&A, HELP AND TROUBLESHOOTING (emphasis added) forum as just the Q&A and forget the last part.

This model has never had an isdue with Sudden Death. I think that's the international models only. If that's what you have, you may want to post this in that forum as they may hsve seen this before.
If I had to guess though, I'd say its more likely a hardware problem. If it were software it would probably hang at the same place every time.
I could be wrong though...

Ah, no, it's a T-mobile. I did notice that sds was in the international forum and was going to check if it applies to the US but forgot. Yeah, I'm leaning towards hardware too. It'd be nice if I could find someone else who has had the same problem and has a diagnosis. The device is out of warranty (It somehow shows water damage though it's never been submerged. Dumb Florida weather...) so I want to evaluate other repair options before considering Samsung. I buy my phones second hand so spending more than $100 fixing it quickly becomes debatably useful. If it's hardware, obviously a JTAG won't fix it. I don't have anything super important on there but do have some game progress I haven't backed up since I started so I'd like to avoid a wipe, which is probably a pipe dream at this point.

Yeah, you could try a factory reset, if you can get into recovery long enough. If it comes to it though you could always sell it for parts. Or buy an s3 with a broken screen and swap parts.
Unless you hear from someone else though, I'm afraid your only way of knowing is to attempt a jtag repair. If it doesn't work, its probably hardware.
Good luck however it goes!

Yeah, recovery usually doesn't even show and only occasionally just gets to the TWRP splash screen so I can't do anything there. Just checked Ebay and was shocked how cheap broken screen S3's are. I have hope! If I just need the mainboard, does the carrier matter? I know roms are interchangeable but I'm not sure where the antennas are tuned for Tmobile's AWS. I imagine it's in the Qualcomm Radio on the mainboard which would require a Tmobile device. Any idea?

I can't say positively, but I'm pretty sure that's correct. AT&Ts I747 will work on T-Mobile networks, but you will never get the performance from it that you would with a T999. If you could find a T999L that would be even better still!
I know the cell radio is built into the SoC (wifi and BT are on a broadcom chip), so the more I think about it the more positive I am that you'd need to try to stick with the T-Mobile device.
Sprint and Verizon devices won't work though, just so you know. Those are CDMA. Yours will need to be GSM. An easy clue to this is if it has a sim card. I'm telling you this becsuse there are still other models out there, and some may or may not work. Just in case you can't find a T999 or T999L.
