Thought Phone was Bricked. Possible Fix for Everyone

The phone was acting like it was bricked.. not sure if it was a bad radio or a rom from another phone.. im really not sure... troubleshooting and looking into files now.
But..
I popped the back off (A few screws simple)
Covered the antenna leads with some non conductive tape and BOOM
Phone rebooted like new.
Here is the issue now
Its back on , i can use it, cell service seems fine and wifi seems fine.. so im assuming the ONE (of 3) antenna i had to leave covered to get to boot was GPS..
So not sure where to go from here.. Did hardreset , factory wipe, Darkside wipe, installed rom , kernal and radio, but still cant uncover the top center antenna lead or i get ZERO response when i close the phone back up.
Hopefully this could be an easy fix to some bricks out there.. ill update this when i find out why i cant uncover this last lead.

Depends what you mean by brick.. A lot of people lately been thinking low battery is bricked or even stuck buttons.
If your phone vibrates when trying to turn it on, then it isn't bricked.

The battery was cool, charged it over night, even tried my back up battery.. for some reason when i popped the back off (the screw on piece not the battery cover) it would turn right on.. but as soon as the contacts touched the back of the phone it would shut off and not respond.. i put tape over them.. wiped it to ****.. used odin to stock.. and then popped tape off the contacts popped the back back on and it works like a champ.. no idea why it worked.. but it did

Thanks for sharing your experience.

Hey the bricked part I think gets thrown around too much I probably would of used a different word but can you help others who may have the same issue in the future and post a pic of exactly what you did to get it working again.
thx

Water on my GNex - Argggghh! - FIXED :)

I just got a tiny amount of water on my GNex and it's acting like it's fried. It indicated that it was charging while not connected. I rebooted and it went in to a bootloop. !?!?!?!?!? This is so frustrating!
Any ideas on a US carrier/phone that's great right now?
---------------------------------------
UPDATED: I looked on ifixit and figured out how to totally disassemble the phone. I then got my wife's hair drier, set it to the cold setting and dried it for ~20 minutes. Afterwards it booted up fine, and seems to be fully functional. The camera got some water in it, and looks foggy, but hopefully that will clear up with time.
Thanks for your help everyone!

Your Phone is Bricked
I will use ODIN.
Download stock firmware for ur phone...and dumping it use odin.
Root.
Start from the begining.......its need many works...trying n try...new rom....ur phone bricked n start from the begining..... again..
Happen to me mny times.....
send from xperia neo v ics...trying to install edt2kernel.1400.oc.zip without custom rom n bootloop in again....
HEY....DON FORGET DO nandroid backup...so u can restore ur stock firmware n skip to install custom rom....much easier.
let me know if i give wrong statement here..i still noob...and not samsung user...

i had this too but without a water accident.
it always switched the "charging" state. maybe your micro usb connector got damaged like in my case.
but maybe you have other damages too because of your bootloop. try flashing the stock android over odin and if the problem(s) persist you'll need to send it to repair or repair it by yourself. usb connectors are cheap in ebay.

When this happens the best thing to do is immediately remove the door, battery, sim, etc and place them all in dry rice for 24 hours.

I'm pretty sure you don't want to use ODIN as this isn't an official Samsung device or something and other, have seen nothing but broken hearts after an ODIN flash.
I had this issue, mine was from getting spray bottle happy when putting on a screen protector. I removed the battery and put the phone in a Ziploc bag full of Rice for 24 hours, has worked perfectly fine ever since.

can someone change the threa title, it should be "announces" and not "releases" -.-

This method works great and saved both my wife's and my brother's phone. My brother dropped the phone into a lake while fishing, it took us about 30 minutes to find it (about 12 feet deep) and by then it was thoroughly soaked. Not really thinking it would work we left it in rice for a week (you could see water sloshing around beneath the screen) . To our surprise it worked perfectly without any problems when we booted it up and it kept working.

Wow, that is really cool. I knew dry rice works well for some water exposure but coming back after being fully submerged for half an hour is next level.:good:

[Q] Water damaged/Bricked??

i dropped my phone last night during heavy rain and forgot about him for about 30-45 mins when i went back out and got it the battery was out. i turned him on and he booted up to the lock screen but then i couldnt unlock it so i turned it off and put it in rice for about 12 hours and i turned it on and it got stuck at the lock screen again. Then it wouldnt boot up past the kernel splash at all nor go into recovery. i got it in download mode and odined to stock but still no go. It seems to be going very very very slow because i just randomlly found it in recovery and the volume controls were very slow and the home button wouldnt do anything. can someone help me? any advice anything to try out? its like its water damaged and bricked.
Edit: i got it to boot but it is the slowest thing ive ever seen. any suggestions?

Sounds like you have a water logged defective unit on your hands. Aside from dismantling the thing and drying out the insides, you probably have a paper weight on your hands.
Sorry man.

thanks for the reply. i guess i need to find a new phone somewhere.

So I ordered a replacment and the guy emphasized on the "as long as its not water damaged" part so does anyone know if theres like a water damage indicator inside the phone that may have changed or show that some water may have gotten in the phone?

Majority of phones have a water saturation indicator on in the inside. However, I couldn't tell you where that is located in our's. You could search a bit on the internet, I'm sure you could find a tear down video or something.

I did a little search and apparently the only indicator is on the battery so I should have no problems. The phone does turn on it just takes about an hour to get passed the Samsung screen so hopefully they wont look too deep for any water problems.

Okay, so after letting my phone sit with no battery for like 5 hours i tried to turn it on and it worked 100%. It was back on stock since i odin'd stock FC09 on it. Then I flashed cwm and restored my backup and i ended up with the same touch screen problems. So now I'm back at the point where i just odin'd stock on my phone and it still won't boot passed the samsung screen. I'm going to take out the battery and let it sit. Can anyone explain why this is happening? Could this one time working event be just a random thing or is it from leaving the phone alone for the few hours I did? Any suggestions or thoughts?

The touch screen problems sound like it's hardware related. As for it not booting passed the sammy screen idk.

[Q] How concerned should I be about my SGS3?

This is a bit of a long story but I need advice and I'm not sure where else to go. I have the phone rooted but the only thing I've done is install KT747.
I'm not sure if it's related but I'll open with that about 6 months ago I dropped it in the bathtub (dumb as hell I know), took it to the sprint store and BSed them about what happened. They opened it up, saw the water indicator/water, called me on my BS, dried it off and cleaned the contacts with rubbing alcohol and my phone came back.
Fast forward to Tuesday, at work with my phone plugged into my laptop it cut off and would simply not come back on. The samsung logo would come up and then the KT747 "Kernel Domination" screen for a moment but then it would cut off. The phone would be on for maybe 3 seconds total. Even if I tried to boot into recovery or even download mode the same thing would occur (I think one time I got it to show the flash count and all that jazz in download mode). As the water indicator will still show water damage and you can clearly tell I've rooted it I was worried I might be screwed out of a phone, but I thought I was screwed the last time I went to sprint so I left to go do that, half way between work and the sprint store my phone cut back on in my pocket. Over the next day and a half it had similar problems but eventually came back (quicker than the first time). And now it's been running well for 3 days.
I've been doing some research on google and I've seen something about a motherboard defect that can cause sudden death, but I think this might be the international S3. It's really hard to tell what's what. Also I saw someone say it could be a battery issue so I ordered a new one but I'm still concerned this might not be the issue.
It's working fine now but I'm in constant fear my phone will just die any moment now.

If it was working fine before you dropped it in the water, then that's probably the cause. I doubt it's sudden death syndrome if there were no signs of shutting on and off before you dropped it in the water.

But would I expect to see problems from water damage so long after the contact with water? I figured if there were going to be problems from the water it would have happened much quicker than this. Like I said the water damage was MONTHS ago.

Sounds like SDS power button failure. Very common on S3.

Help!!

Hey.. I flashed cm12 unofficial ROM 2-3 months ago on my lg d855.. There weren't any major bugs.. But recently I noticed that sometimes when I press the power button to unlock it .. The touch screen seems to stop working.. This happens only on the lock screen... I Also tried holding the power button and try to tap the "power off / reboot" buttons.. It doesn't work too.. But.. The weird part is..when I sort of slap the screen it starts to work again .. My question is .. Is it a ROM bug? Or is it a hardware issue.. If its a software issue.. Then why does it start working when I slap it.. And if its a hardware issue.. Why does it only occur on the lock screen? Please help.. Thanks

I haven't had this problem on the D851, but I would try updating your device to the newest version of Cyanogenmod.
Also, back when I had the G2 I went through this problem a lot and actually had about five of them because they were under warranty. The problem was that the seal for the screen would come undone, and it's hard to notice since the screen is literally the entire front of the phone. When this seal broke, water would seep in and cause chaos with the screen. Wouldn't work in certain parts and so much more. I haven't had this happen on the G3, but my seal has broken and I can see it, so it's only a matter of time before water gets in there (or until I get the screen replaced). I've always had this problem with LGs they're just so damn good that I live with it. I'd bet this is what's going on if it's not the hardware.

Absolutely... I can see... Whenever I press on the edges on any of the sides.. It sort of gets pushed in.. It looks like its not glued properly.. Its a bummer as the "screen" is the reason y I bought this.. From ur experience , does it stop working completely at some point?

If you can push it in then the seal is definitely broken.
On my G2, when in a moist and humid environment condensation would form on the inside of the device, but it was nothing too big and went away after a while. However, when too much fluid built up in the inside it began typing on its own. Furthermore, it got to the point where certain parts of the screen were unresponsive. This is why I had about five of them because over time it did get bad.
Although if there is water in the device rice usually absorbs it. Get a ziplock bag and fill it with rice. Take your battery, sim card, and sd card out, then place the phone in the bag full of rice. Seal it and shake it up a bit and let it sit over night. Keep the back cover off as well. If this is an option. I understand you might need your phone, but if you get a time where about eight hours are free I would highly recommend this. I have no idea how it works, but it takes the moisture out of the phone. I've done this with waterlogged phones, my G2, etc.
When I did that on the G2 it fixed my problems until moisture got back in there. I don't take care of my phones too well, so moisture got back in fast. Try this out and if it works just avoid keeping your phone in moist places (like playing music in shower, being on it while raining, etc.). If this fixes the problem it should hold you off until you can get the screen resealed or a new screen.
If it is with the hardware and its still under warranty I would get a replacement. I would revert to the stock ROM (if you made a backup) or find one and make sure it's updated. I would then do a full unroot, and attempt to make it so they cannot tell it was rooted. I would then attempt to get the replacement. Rooting voids the warranty, but if you unrooted I doubt they could tell. Furthermore, if you have insurance on the phone this could also work.
Edit: If you try the rice then try to replace the screen I would ensure that the current screen works properly after the rice. Make sure all the moisture is out before you replace the screen that way no moisture is trapped in there.

First of all.. Thank you soo much.. Thank you for the time.u put into these posts.. It has really helped me.out a lot.. I can totally see how the rice method could work.. But it has not got to the point where its un-usable.. As I said, its only in the lock screen.. It has never ever occurred during actually using it.. I haven't found any dead spots.. Nothing.. If I use the rice trick to take out the moisture,, and if I can use the same screen (which should still work) can I just take it out and glue it in to place? What type of adhesive should be good... I'm asking this because I got this from abroad.. And it's not an international warranty. So there's no way I'm getting a warranty replacement .. So ive gotta make with what I have.. But this is very sad though, specially from such a big company.. I mean gluing a screen is not that hard.. I played loads.. Lol.. I really hope hot glue works lol..

Well then I'd try to fix it before it does get unstable! Thing with the lock screen is you're swiping and the moisture defuses the area you're touching which could cause problems. Definitely try the rice! However, I wouldn't recommend gluing it yourself. I imagine it requires some sort of water and heat resistant glue to be effective, and on top of that a professional application. Hot glue definitely won't work! I imagine you want something that looks nice and I can only seeing that being messy and leaving residue. Furthermore, I'm not entirely sure on what lies beneath the screen and if disturbing that could cause further problems. However, I understand you're probably planning on it so please watch a guide such as: https://www.youtube.com/watch?v=PcoEQVtUwYQ to see how it's done and what you need. There seems to be a lot more to it than just placing some glue on the screen and pressing it back down.
I'm sure you can get a replacement kit with instructions and all the required tools to do it properly for not too steep of a price. Check this out: http://www.ebay.com/itm/Replacement...46?pt=LH_DefaultDomain_15&hash=item54198f441a
Or you could take it to a professional like those at Broke Ass Phone: http://www.brokeassphone.com/smartphone-repair-selection/lg-smartphone-repair/lg-g3/ The price is steep, but it's professionally done and comes with a warranty.
Good luck to you!

Hi, ItsJacobee,
Sorry for breaking in, I have the same issue with 2000ftt, and I did tried "rice trick" but no luck. I think the screen is perfectly fitted in the case, when I press the edges, the feel is solid and no room for further pressing in.
My device is D855, I flashed many custom roms (resurrectionremix, CM12, Nameless ROM, CloudyG3 2.1), the mentioned issue happens to many of them but never happened in CloudyG3 & stock rom.
Any idea?
Best regards.

Yes, it is under warranty, I am going to restore stock ROM and take it to service center. But I don't know how to trigger the issue (touch screen no response at lock screen while using power button to wake up), in stock rom and cloudyG3, this problem never happen.

Thanks for reminding. I restored the phone to stock with the downloaded .TOT file, then go to service center.
I can't trigger the problem in front of the service guy, however, they ask me to left the phone for checking, one day later, they confirmed that my phone is working fine no need to do anything, nothing to be replaced.
CM12 is already good enough, its speed and battery friendly....
I wish developers of CM12 would somehow fix the problem in future updates, as I knew some D855 user (but not much) also having the same issue.
Best regards,
