Samsung S3 Dead - Galaxy S III Q&A, Help & Troubleshooting

Hi! This morning when i woke up my phone (s3 i9300) was working ok, then i've rebooted it and had shown random pixel colours while shutting down, at this point i've disconnected the battery, reconnected and from that is completely dead...
No boot with volume up/down+home+power.
I get 2.8ma of consumption when i connect the battery, then after few moments goes to near 0.5ma, when i press the power button goes to 280ma, when i release it i get back the 0.5ma. When i connect the battery i have around 2.10v between the contacts of the power button (3.95 reference to ground)
What i can check to try to find the cause? I have an hot air reworking station, cap meter, etc, but i not have enough phone electronics background knowledge (i not repair phones for job, only some minor electronic repairs sometime). I've seen videos about problematic caps, power ic and emmc, but i not know the "debug" steps to find the defective part....
I have full backup of anything, i know that it's an old phone, now it's quite slow, but was doing it's job....
Any help is really appreciated! Really thanks!

I'm trying to unbrick it using the SD card (found some instructions on the net), but i can't get it to boot constantly from the sd (also without the jumper on the resistor). Sometimes it boot (and give the SDCARD download failed - due to the missing jumper on resistor) but most of the times don't do nothing (tried different "press times" on the power button). One time that i can get it booting constantly from sd, i try to short the resistor... I'm trying with external power source (usb cable) or battery, also with both of them, but as said the device not goes always in the download screen...

If you can get download mode you need to flash the latest official firmware via odin on a PC.
For the sdcard method to work the file must be on internal sd, not external sd.
Beamed in by telepathy

I'm following the instructions found on the samsung release note (and also some posts here), but instead of creating the sdcard from a working s3, i've writed the "ready to use" image (written with image write). It works as it goes into the sdcard download screen, but only one time over a lot of tries. At this point i not think anymore that is only a software problem (emmc corrupted), but also an hardware problem. And also if it's an emmc failing, i not understand why not goes on the sdcard download screen every time, so i suspect that is something about the power circuit... I'll try to replace the power ic and check the capacitors around it....

Is my phone bricked?! (grey battery screen)

Hi guys,
I figured I'll post again here since I think I bricked my phone.... I was trying to install Eugene's Vibrant6.zip and I got stuck on the Vibrant Logo with Samsung at the bottom. I tried to reset with both volume buttons and power button and got to grey battery and nothing else...
What I did prior to this was I formatted system and data on the recovery screen as per some posts here and it would just boot into a loop. Windows won't recognize a device and it just shows grey battery image and it doesn't seem to be charging. Anyone can help me?
EDIT:
Out and in the battery, plugged in to USB and it just loads the battery image and it's all grey color as if fully discharged and just stuck on it. Device is also not found in my system so I can't do any adb commands. If I just reset it without the cable it would just sit on the Samsung boot loop. Anything I can do?
UPDATE: Ok, some good news! I heard the sound as it connected via USB, I can see the 2 drives, but they read as Removable Disk and I can't access them...
adb reboot recovery or download
error: device not found
What if simply format the drives via Windows right click menu? Will that do any good or bad? What are my options here? Any help will be appreciated!
UPDATE: Well... looks like this is pretty much a dead phone.... I right clicked and selected Format in My Computer and it just says There is no disk in Driver F: Insert a disk and try again.
Can I a mount an image somehow via MagicISO? Or is there something simpler that I just can't figure out?
Again, thanks for your help!
Thanks.
Has anyone experienced this or am I the only one?

Sorry I have never heard of this or witnessed it while flashing anything to my device. Obviously the battery screen signifies that the phone is off but is in charging mode and hitting the power button will boot the device up. (I'm sure you already know of this). Never heard of it being stuck at that screen after flashing. Hopefully you can get this solved soon. Good luck

Slow down for a second. Your phone is definitely not bricked. Ive been over the edge, and been able to bring my phone back to life.
To clarify, you flashed vibrant6.zip through clockwork mod, and then the phone got stuck on the samsung S? How long did you let it sit there?
It sounds like just your ROM is messed up.
Are you able to "get into recovery"? Holding both volume buttons while you power on the phone, without it being plugged into usb.
Do you have Odin? And have you ever used it?
Its totally frustrating when your phone gets messed up and you don't know what to do.
I flashed the stock ROM via Odin and then wanted to install Vibrant6.zip. For that I entered into a recovery mode via Clockwork and as someone in the other thread advised, I formatted system and also data, don't recall exactly. Then it looped to a standard recovery mode and I just rebooted the phone. This is where it got stuck... Vibrant in the center and Samsung at the bottom of the screen. To test it I left it like that from night till this morning. In the morning I woke up it was on the same boot screen.
Before that at night, after seeing it hand at the boot, I held both volume keys and power, waited for it to reboot, and immediately it showed a circular progress bar, but not moving just highlighted the 12 o'clock bar and second later I see the battery image all in gray and nothing else. It just sits on that grey static image without actually charging it (no green section or flashing dots)
Boot logo only appears if I am trying to reset without the USB cable. On the boot loop I plug in the cable and I hear the USB connecting it, I see the 2 Removable disks, but both inaccessible and adb commands don't recognize the device.
Very weird, as in turned off mode it's not charging at all.. just shows this grey battery image with a circle progress froze on 12 o'clock bar.
That's pretty much it.... I was never able to enter into recovery nor download via the buttons. It would just always reboot into this grey battery screen....
Completely helpless.... I did order a new battery from TMO, maybe the battery is fried and that's why it's not charging and just sits on this stupid static grey battery screen.

Holding both volume keys and releasing power once screen goes blank, only show Vibrant logo again... I have tried this a million times
With USB cable it shows grey battery screen, without the cable just a Vibrant boot loop...
I'm assuming that you have the Samsung drivers installed.
Try the following steps:
Take out the battery and then put it back in but don't turn the phone on.
Plug it via USB.. does anything show up on the screen?

Yes, I have the drivers installed as I was able to locate my device and use adb commands to enter into recovery and download. Also Kies worked.
Doing what you asked simply load the grey battery image and nothing else with a progress bar not spinning. Just sort of hangs on this image and that's all.
Booting without the USB cable loads the Vibrant boot loop. Connecting USB at this boot loop state, would play a sound as if it connected to my windows, but I can only see Removable disks that are inaccessible and adb doesn't find the device...
Very strange.... trying to use the button keys to enter into recovery or download is no use, as that just won't ever happen, even when phone was working fine.
Any other suggestions? I would return the phone for replacement... but I am not sure how it would look with all the files still on the internal disk including root if I am not mistaken... I had only few hours of sleep because of this headache

Are you sure that you're doing the right things to get to download? I've been in this situation and I wasn't able to get into recovery but I was able to get back into download mode.
I believe if you return it back and they find out it was rooted, they will charge you for it. If not, it'll appear on your bill.
I'm sure that you're doing the wrong things to get into download mode. If something is appearing on your screen it is a soft-brick and you're not bricked.
1. Take out battery, put it back in. (to turn the phone fully off)
2. Don't turn it the phone on!
3. Plug the phone into your PC, do not hit the power button!
4. See if the phone shows anything on the screen (powers on its own when plugged in)
IF the phone screen does 'turn on' after being plugged in without you hitting the power button, so far so good.
5. Now while it's on like this, hold the volume up and volume down buttons.
6. Hold the power button as well as the volume buttons until the screen goes black.
7. As soon as the screen goes black, let go of the power button! But DON'T let go of the volume buttons!

A tip to get into download mode is to put the phone HORIZONTALLY (sideways) and it will make it a lot easier.
I am pretty much positive about it. I know a lot of people can easily enter into recovery or download modes, but I know many can't and I am one of them. It would just load the grey battery image instantly as I let go of the power button.
1. Take out battery, put it back in. (to turn the phone fully off) DONE
2. Don't turn it the phone on! DONE
3. Plug the phone into your PC, do not hit the power button! DONE
4. See if the phone shows anything on the screen (powers on its own when plugged in) FIRST THING THAT APPEARS IS A CIRCULAR PROGRESS BAR THAT CHANGES TO A GREY BATTERY IMAGE WITH A BAR IN THE MIDDLE OF IT. STATIC IMAGE, NOTHING ELSE.
IF the phone screen does 'turn on' after being plugged in without you hitting the power button, so far so good.
5. Now while it's on like this, hold the volume up and volume down buttons. DONE

7. As soon as the screen goes black, let go of the power button! But DON'T let go of the volume buttons! DONE
THE STUPID GREY COLOR BATTERY IMAGE APPEARS AS BEFORE....
I'm thinking maybe battery is fried and that's why the grey color screen appears and not the usual screen where you see the battery charging...
After reading this thread it's clear that my handset is one of the new ones that have recovery/download modes disabled via the volume+power buttons.
So that pretty much covers it... I hope TMO will not ***** about the files that are on the internal sd that I am unable to access and remove... unless anyone else has any fresh ideals how to gain access to the disk
I think I might have a similar problem.
I accidentally deleted the touchwiz framework so I can't do anything ON the phone. It boots up, and gets me to the lock screen. As soon as I unlock, I am greeted with dozens of unending force closes.
I can get into both download and recovery mode, however, I have not been able to get ADB to recognize the device. I am attempting to push the stock ROM to the internal memory to flash over everything.
I'm not sure what to do to get ADB to work but it's driving me nuts!
Stuck at vibrant? I have a fix
Check out android Dev Section... I figured out how to access download mode or stock recovery mode when you are stuck at the vibrant screen!!!! BACK IN BUSINESS VIBRANT OWNERS!!!
i got the same problem and nothing seems to work
Try this out http://forum.xda-developers.com/showthread.php?t=1103706
Feels like I'm having same issues..
the previous post requires opening the phone and I don't have tools for that..
Here's my issue.
I can't get into Recovery or Download and computer won't see phone to Odin.
I've got drivers installed and AIO Toolbox as well as ADB(which won't work because of computer not seeing phone.
Using the manual option(vol+ vol- power), nothing works.
I've done all the tricks like unplug it then hold vol keys plug it insert battery..
When I do plug in the phone to to even just get a charge in it goes the the battery, but my is is frozen or something. doesn't turn green or have a charging animation. After about a minute or so it was start up and boot loop. I read something about a bad battery? I've got two of them and they seemed fine before..
Before all this I had to Odin and go to stock. I was attempting to get ics back but I was being lazy and trying to do as little as possible..bad idea. I was following slim ics install and flashed cm9 daily, slimics and commons..and now this..
I'm not sure what to do..I usually search around xda or google..10 hours later.. idk..Anyone able to give help please?

Try asking another question. But I suggest using a USB jig. They usually work. Then odin
Sent from Mount Olympus via Hermes
Did you ever get it fixed man? I literally did the very same to mine a while back and It works like butter as we speak. It is fixable with a mini-usb jig or dongle. You can make your own with about $3 worth of parts from radio shack but I recommend buying one, it will be easier. I for the record made mine simply twisting together the resistors and though it was tough to touch the right pins it did eventually work and get me back into download mode.
Hopefully you already got it fixed though. If not I can help you out.

[Q] Bricked phone - Boot loop - Recovery & Download mode not working [HELP]

Hello guys,
I've got a big problem with my I9300 and therefore I would like to ask here for any help. (If I'm in the wrong section, please move the thread to a correct one)
I had installed the Resurrection Remix ROM, v5.2.6. from 30.12.2014 and Googy-Max 2 recovery (CWM based) on my phone. I was using it for days and all worked fine.
One day I turned the phone off and I wanted to restart it. But it never restarted again; it ends up in a boot loop. It shows me the white Samsung Boot-Logo for some seconds, then a total black screen and the same thing repeats in a loop.
So I wanted to get into the recovery for wiping etc. but I couldn’t access the recovery. Nothing happens by pressing the relevant buttons. The device is still hanging in the boot loop. So I wanted to flash via Odin, but this isn't possible. I also can't go into the download mode. After pressing the relevant buttons, the green warning screen appears, which asks me if I really want to go to the download mode. But when I press volume up for "continue" or even if I don't press anything, the phone turns off and the boot loop with the white Samsung Logo starts again.
Therefore I ordered a USB JIG for forcing the device to go into download mode. When I plug the USB JIG in, the device actually goes into download mode but this status holds on only for a few seconds. After accessing download mode through the JIG, after a few seconds the phone turns off, restarts, (and because the JIG is still plugged in) the download mode appears again and it ends in a loop.
At first I thought maybe the power button is sticking and therefore the device turns on and off autonomous. But definitively I can negate it, because I opened the phone and removed the power button and nothing changed. Also by pressing the power button on the mainboard I can clearly hear the "click".
So I started a new attempt. Although the time, in which the device stays in download mode before turning off, is very short (only a few seconds), I tried flashing an other recovery, namely TWRP v2.8.3.0. So I prepared ODIN, plugged the JIG into the device, by appearing the download mode I switched cables and an other person clicked start at ODIN and it worked. So now TWRP is installed. Now I also can't get into recovery but after flashing TWRP there exist two little differences. First, after pressing the relevant buttons, TWRP appears for less than 1 second until the phone turns off. Secondly, when I plug the device in for charging, the Samsung charging logo appears for some seconds, then for less than 1 second appears a charging logo from Lollipop and the device ends up in a loop by displaying alternately the two different charging logos. Before flashing TWRP, the device booted in a boot loop (as I wrote above) by plugging it in for charging.
So the main question: how can I get my device work again
I tried telling you all details so that you have a better view of the problem.
Maybe I should flash a fully (stock) rom, but as I told you the download mode appears only for a few seconds. Flashing a recovery was possible, because the recovery file is very small - 7 MB. A full rom is much bigger and I think by flashing a complete rom, the device would turn off while Odin is flashing, therefore I ask first here for any assistance.
Thank you very much in advance!

Check and make sure that your volume buttons and home button are not stuck also. If they are not, I would suggest a visit to a repair shop as your EMMC chip might be weak already.

Your power button is failing, stuck in 'pressed' position. Try pressing repeatedly power button for several seconds, then release it completely. It shall bring it back to life. Visit your local service, or prepare tin, heat gun and soldering pistol. One button cost $0.2, they are selling them on eBay in sets of three (and 10, and 100....).
Happened to me some time ago, and video on youtube helped me to dismantle my phone, pull broken button out of it, and change it for new.
My phone was cycling like yours.

As said your emmc chip maybe failing.
The dead boot thread maybe of interest to you.

Your power button is failing, stuck in 'pressed' position. Try pressing repeatedly power button for several seconds, then release it completely. It shall bring it back to life. Visit your local service, or prepare tin, heat gun and soldering pistol. One button cost $0.2, they are selling them on eBay in sets of three (and 10, and 100....).
Happened to me some time ago, and video on youtube helped me to dismantle my phone, pull broken button out of it, and change it for new.
My phone was cycling like yours.

He said he has tested this and can also hear the micro-switch clicking.

Check and make sure that your volume buttons and home button are not stuck also. If they are not, I would suggest a visit to a repair shop as your EMMC chip might be weak already.

Thank you very much for helping! :good:
So the question is, whether it's the power button's or emmc's fault...
I did a little searching and found this video. I've got exactly the same problem like the guy. At 1:06 following the boot loop, at 1:34 following the problem with downlod mode.
Although he thinks it's caused to the sudden death problem, but at least in my case I think it's wrong because months ago I did the eMMC Brickbug Check.
Also I noticed a probably important detail. When I put the battery in the phone, it automatically turns on without pressing the power button like in 1:04-1:09 in the video. Which normal working phone turns itself on by simply putting in the battery...?
So it must get a command for turning on - (possibly through a defect power button?)
@Virnik0, do you remember, if you could hear the micro-switch clicking on your phone before replacing the button on the mainboard?

Your power button is faulty, replace it before you try fixing anything else.
Thank you very, very much for helping! :good: :good: :good:
Truly the power button was fault although you could hear clearly the "click".
I unsoldered and removed the power module and (by startig with JIG and rebooting via ADB) the phone works as it should. :victory:
Now I'm trying to solder a new power button......it's a bit tricky
Again, thank you very much guys!
I had the same problem, pressed the button many times, and it helped. Thank you for your suggestions

Stuck In Boot Loop - Boot Failure on LG Page at Start Up

I have gone through other forum entries that were similar and did not see anything exactly the same. Came back to G3 after 6 months since I had the common issue of screen freeze/flicker and fading out. I did paper trick where folded paper goes over camera port on motherboard to get it at least temporarily functional. That did the trick as far as screen working for now.
My major problem began when I tried utilizing this technique I found in forum in hope of a more permanent solution:
I spent days of googling and there are only temporary solutions for this problem.
After testing my phone for 2 days in different conditions I realised that the screen is going crazy when the light is changing too much.
If you do a sensor calibration everything will go back to normal:
-enter in Hidden Menu (model dependent)
-select Device Test
-select MT
-OK to restart the device
-OK and do not touch the screen for few seconds
-go to Individual Items+Power (you must push power button when you select this item)
-select Sensor Test and take care to not block the proximity sensor when you make the selection
I got as far as MT in device test and phone restarted. However, it won't get past the first LG screen. It hangs there for a few seconds and the words "Boot Failure" appear. Is there anything I can do to get out of this boot loop. I tried hard reset with volume down and power and get same result. I also tried hooking into PC using volume up for download mode and get nowhere with that either. Is there anything else I can try to fix this problem?
I greatly appreciate any help anyone can provide. I did notice the last resort debrick method by R-T-B but it seems a little complicated for me and I was hoping there might be an easier solution.
When you tried to put the phone in download mode, did you use the original cable, and use it with a USB 2.0 port that comes directly off of your PC's motherboard, not USB 3.x and boy through a USB hub?
If so, what happened exactly?
Yes, I used original cable and made sure it was USB 2.0 port. I hold volume up button and plug other end of USB cable into phone and it goes right to the black screen with just LG logo and Life's Good. Directly under the logo in white font is Boot Failure. I can't seem to get past it. Phone will shut down by itself and automatically turn back on going to same boot failure page.
One thing I forgot to mention in original post. I had not used phone in a few months and forgot I had taken SD card out. So when I did the MT in device test SD card was not there. Also, phone is rooted. I had a Jasmine ROM 9.0 or 9.1 (35B). I have put back SD card into phone which I am not sure matters or not but get same result.
SD card shouldn't matter for anything.
What does it say in Windows' Device Manager in the ports section when you attempt to put it into Download mode? LGE... or QHSUSB_BULK 9008 mode?
It shows LGE Mobile USB Serial Port. When I enable show hidden devices it shows 2 LGE items under Ports. One has COM4 and the other COM41.
Also, USB 2.0 connection to PC is directly to port on back of PC. Not connected through hub or anything. Also, although I don't know if it matters but I had TWRP flashed as well.
Its frustrating that I can't get phone to do anything but reboot back to LG screen. I don't understand why just going into Hidden Menu got phone stuck in never ending boot loop. I could understand if I flashed something wrong but I didn't do anything like that. At this point I don't care about any files or anything on phone, just want to get it in working condition.
There are a lot of dangerous things in the hidden menu, that's why it's hidden.
If you continue to not be able to get it into Download mode, look at the thread in the General section for forcing it into QHSUSB BULK 9008 mode, and then there are different recovery instructions that still needs the 10B TOT.
Or @R-T-B might be able to fix it for you. I don't know what the deal is with two LGE devices showing, bit I've never taken any steps to show hidden devices.
Won't hurt to try flashing the 10B TOT even though there phone doesn't look like it's in Download mode. I don't know if the existing hidden port 41 LGE device would be sufficient or if you should change to port 5 one to 41. Normally you have to change the port 5 one, but both are worth a try.
Of course, it the phone constantly reboots too quickly to try flashing, then ignore that advice.
Sounds stupid I know but try anything like leaving the SIM card and Micro SD card out?
FYI apparently it seems normal that enabling hidden devices in Device Manager would show the Port 41 LGE entry. I flashed the 10B TOT to my wife's phone and after it booted and I enabled hidden devices, I could see the "new" valid entry on Port 5 and the old hidden entry on Port 41, so it's no matter, and if you choose to change the Port 5 one to Port 41, just proceed even though it warns you there's another device on that Port. A reboot of your PC might fix it too.

Did you ever get this sorted out? My g3 same thing. Hidden menu, device test, and then reboot but stuck at lg logo screen. I’m unable to bring up mini os for the hidden menu to escape the device test action. It just stays on with the lg logo on the screen.
Thanks for helping.

Help with recovering Galaxy S3 from bootloop.

Alright, so I recently obtained a Samsung galaxy s3, ( Model# SCH-I535). The previous owner got mixed in with the wrong people who put a screen mirror application in the phone ans was able to hide it from the installed apps inside the device along with a few other spy apps. I got a hold of it and rooted it using kingoroot and proceeded to delete the bloatware and things I did not need, along with those spyware apps that was previously installed on the device. Then my guy was looking at What I did to the phone after stripping down the phone to the basics and he was checking out kingoroot and found the system apps and started deleting everything that he did not recognise, mind you he is not tech savvy, so therefore he didnt know 70% of what was on the phone. Then after he hit the home button and realized that he removed the home launcher, or moreless that he had a black screen with errors stating the home screen has stopped, he took the battery out and handed me the phone telling me that it cant be fixed so now can have it. I knew that I could flash a new rom on it ans recover it somehow, so I spliced a usb charger cord and wired the usb end of the charger to the terminals next to the battery compartment and ran 2 small wires to the battery terminal itself and was able to get power back to my phone as long as I remained plugged in to a usb power source. So now comes my problem and reasoning for this thread..
I do not have a working computer or Wi-Fi at my home other than my hotspot from my phone that I primarily use. And that s3 is stuck in a bootloop, or now more of a steady screen, stuck on the verizon wireless screen. But I do have several flash drives and external hard drives with the universal charger hookup that most androids currently use along with a usb connected that allows me to use my flash drives with my phone.
Is there a way that I can recover my s3 from this?
My goal is to get this phone back on working order and keep it rooted to strictly run Kali and keep a 500gb external hdd hooked up to it permanently to hold all of the toola that Kali provides.
Any help or suggestions with this would greatly be appreciated.

Here is what I would suggest. You could do one of 2 things. When powering on your device, hold the power+home+volume up button to go to recovery. Wipe your data and reboot the phone. It will do a factory reset and you can root it again. Or if you hold the power+home+volume down button, you can go to odin mode. You can flash the original firmware back to the device. Keep in mind you gotta have the odin tool downloaded on your computer, the drivers, and the tar.md5 AP file.

Yup, tried both. Don't have a working computer. And even wiped the case partition several times and update from cashw and reset countless times. But I was messing with it before work and got it to come on. But my keyboard is out. So while I have time today at work I'm gonna download a launcher and a keyboard ask and put my sd in it so I can actually get somewhere with it
Ok, so now I have the problem where I plug it in and it just vibrates and is a pain to get into recovery mode. But I can wipe my cashe now and factory reset and get in, still no keyboard or home launcher. But I do have the apks for them. But I only have about 5 minutes until it restarts itself. Its a tricky one. But I do beloeve that the s3 will be worth it with its vast variety of developer options and an seemingly unlimited variety of custom roms

Samsung S+ only boots to 'Download Mode' - Any guidance?

Hello,
New to the forum and all of this, so please go easy on me.
I have a Samsung Galaxy S9+ (SM-G960F).
On Thursday evening, I went to the device and it was completely dead. It wouldn't turn on and I attempted to do power key/volume down and various other button combinations I found online that would normally boot the device. Obviously, I attempted to charge the phone, but the charging light did not come on yet the phone did warm up slightly as if it was charging. After leaving it plugged in for so long, a 'Downloading... Do Not Turn Target Off' screen appeared. It also states I can restart the phone by holding volume down/power button for seven seconds. However, when I do this the phone just goes dead and doesn't boot up. After plugging in the charger again trying various buttons, I eventually end up back at the same download screen.
I've read about recovery mode, safe mode etc but I am unable to access them using the instructions I've read.
Any help would be appreciated. Ideally I'd like to be able to access my photos/videos/messages on the device and be able to use it again.
