[Q] Very strange problem - Galaxy S III Q&A, Help & Troubleshooting

It is a international galaxy s3 with stock rom. Whenever restarting led flashlight is on for few seconds and its booting only in safe mode. So i re flashed stock rom using odin but then also booting in safe mode only. When we enter download mode flashlight is on continuously and in recovery mode the side volume keys are not working so that we cant wipe or do anything in recovery mode. I tried different methods to boot the phone in normal mode but nothing works. I formatted everything sd card, system pre cache dalvik nothing works. Please tell me a solution. Its a hardware or software problem??? Anyone having this problem??:crying:

I think I'm SOL

I have GS3 i9300 I got from someone off of craigslist. The phone was working fine when I tested it. I guess the forgot to take off a passcode . (Yes I feel dumb) . So now I'm locked out of the phone. When I tried to put it in download mode to reset the whole phone new , I get the dead android and the red triangle . Help Please ! I'll even donate ! :crying:
Looks like you need to read and understand the basics before you do anything else.
Go to general forum, stickies and learn about recovery mode and how to factory reset.

[Q] Stuck in bootloop, no download/recovery mode possible

Hello everybody,
I have been browsing the internet and the xda forum for over 2 hours, but I still can't seem to find an answer to fix my problem. I have the Samsung Galaxy SIII GT-I9300 (international version).
My device was rooted over 2 months ago, and since about 3 or 4 weeks I use the stock rom again, but I still have SuperUser. A few times my device was frozen, but generally it works like a charm. Rarely I encounter a bootloop, but it always eventuallly manages to boot correctly. Except for today. I was doing nothing special with my device. It just started to reboot, but became stuck into a bootloop.
I have tried:
- pulling out the battery
- connecting with my PC
- starting download mode
- starting recovery mode
It all won't work. When I start download mode, I get the screen where I should push the volume UP button to continue and DOWN to restart. Pushing the volume UP button does not work, it just starts rebooting again. Also, getting to that screen, connecting with PC and then pushing UP does not work either. Releasing the buttons in different orders does also not work. The same holds for recovery mode; the Team Win logo appears for not even a second, and then my device starts rebooting again. I want to flash another kernel or use samsung kies to intialize software updates/reset (tools), but I just can't get it into download mode.
Moreover, I just noticed that it might also be the power button. I can also get to the continue/restart screen of dowload modus, only holding the home button and the volume down button, without pressing the power button. However, moving it (wricking with a paperclip etc.) does not have any effect on it.
What should I do?
ps: I am sorry if this is in the wrong section of the forum.
pps: I completely pulled out the power on/off button, still no change
ps: I am sorry if this is in the wrong section of the forum.
Use the report button and ask a mod to move it ..

I already looked in all those posts, but it is not a (half) SDS, as one should then be able to enter download mode, which I clearly can't. If the answer was already on the forum, I think I would already have found it, since I have been searching for hours.
Jep it's the home button. If I slam it towards my desk it sometimes starts (but immediately reboots). Stupid phone :/

It has multiple posts and one guy gave a fix .
I find myself in the same position with my phone. It just boots up to the samsung logo and won't go past it. I tried putting it in download mode, when it takes me there and i press the up vol button it just reboots to the samsung screen, same applies for recovery only that it lasts just a second in recovery mode and reboots again. I have also searched everywhere for the past 24 hrs now with no results.:crying: I was running Archidroids Omni kitkat rom with no problems at all when all of a sudden this happened. Is this a soft or hard brick and is there a solution for this. Any help will be appreciated
Its Up Again!!!!
Well what do you know. My phone started up after 6 days of playing dead. I tried everything in the book to get it to boot up, finally i decided to let it bootloop till it discharged to see if I could just charge it and try getting into download mode. Well after the discharge, plugged in the charger and it just kept blinking the battery icon without indication of charging. Got tired, pulled out the sim and sdcard with intention of taking it in for repairs to see if it was a hardware issue. When i got there was trying to demonstrate the problem, so put in the battery no sim or sdcard and she just booted up.
I have reflashed the rom, just to be sure is not some conflict of some sort and have restarted the phone a couple of times been using it for like the past 4 hours and she is still good.:victory:

[Q] S3 I9300 Stuck on safe mode

Hi friends, after a lot of research and web searching i'm totally out of ideas and options
The problem: My S3 I9300 reboot in safe mode every time, is has been doing it since the past sunday. Another tip is that the volume buton down seems not work but only in CM Recovery or in the running software itselfs, it work correctly in donwload mode since i can reboot by presin the buton down. Another interesting fact is thath when I reboot the phone it start the led until it comes the Galaxy S 3 Logo (by presing the button down it power downs the led).
The posible solutions:
Reboot
Reboot after take the battery for a few minutes
Reboot after take the battery out for hours
Flash Custom Cyanogenmod
Flash back stock s3 Jelly Bean (various ROM)
Try to press volume up, volume down, menu capacitive, back capacitive keys and nothing.
Take it to technical service (every one say it was software, but want to charge me a lot of money, talking about an hardware box "especially for flash samsungs")
I have done all the things that I expose before and possible anothers that I don't remember right now, and nothing works, it continuos rebooting into safe mode.
I have too read a lot on google and here and any of the posted solutions works for me.
Do anyone know how to solve this?
Really need help, thanks you all before hand!
Read the sticky thread efs 'know this stuff', safe mode is usually related to efs corruption.
efs + safe mode
Thanks for the answer, I checked the post about efs, and i dons't mention Safe mode anywhere, but mentions factory mode, i'm thinking that maybe replacing the efs with te back up that i did that will solve the problem, but in safe mode you can't use any app like root explorer or similiar, and my back up is a mere copy of the folder efs, not tar not zip not md5. any helpfull guide about this?
PD: im reading on internet and searching thanks!
hardware failure
Hi, I take the phone to repair services, they said to me it's the logical main board that has a fail and that is causing the phone to go in Safe Mode every reboot, the cost of repair it is almost the price of the s3 new so i need another solution.
I believe that the bootloader is resposable for sending the phone on safe mode, is anyway known to disable it?
Another possible solution is use some part of the ICS software since when i flash an ICS ROM it let me use the phone and don't send me to safe mode the problem is that it loses the IMEI and can't restore the efs folder because of the version change (i read here that JB have a different efs format thatn ICS)
Anyone ?

[Q] Bootloop and Download access fail

Hi guys. I have seen and read through plenty of the same problems regarding the bootloop issue on the forum. I seem to be stuck somewhere different so I post this question. I hope someone can help.
I have a standard S3 I-9305 LTE in South Africa. Not rooted before or any mods. But somehow it started bootlooping a couple of weeks ago. I read and implemented the Recovery Mode- Cleared the cache and then rebooted, and it worked, plenty of times.
But now it has gone into a solid bootloop and i cannot access recovery mode. So read up about Download mode and installed Odin, Kies and the Cf Root file on my PC.
Now when I enter Download mode on the phone, and continue( press Volume Up) after the warning, the device restarts again. This I have done a hundred times and each time removing battery and waiting a couple of minutes. So essentially I cannot get Download mode to function but I do have access to it.
So this I know, this is a software , possible ROM problem, NOT hardware as the device worked perfectly after bootloop issue started.
I did the latest Firmware Upgrade to Android 4.2( i think, i r noob in this) yesterday. This was done on the phone itself under About-check-firmware. The Phone worked fine afterwards but then went into this never ending tormenting bootloop without yielding.
I live far from a proper service centre and I need my phone for work, thus very urgent.
I also have checked if the power button is stuck but it is not.
I am prepared to root the device and install any other ROM, Flash anything that can get me back on.
Any advice please?
Thanks in advance
Report your own post and ask a moderator to move it to the i9305 q&a forum.
Sounds like the emmc chip is corrupt or damaged, you may require a new motherboard.
Try plugging your phone into pc before you access download mode, remove the battery before you press volume up.

Hi Boom,
I have seen you have diligently answered many queries, please to be cautious saying it is a motherboard or hardware issue, it makes peoples heart sink before trying other avenues first. But don't get me wrong, the fact that you took the time to answer me makes you my hero. :good: And thanks.
I will try the other option you gave as I know the phone is fine the answer is just a few tries away.

[Q] Need Some Urgent Help With My GT-i9300

Tried installing kitkat on my gt-i9300.
now this is how it looks like ...
i dont know where i went wrong ...
but is there anyway to make this right ??
Please read the guides and stickies again!
First thing first have you backed up your efs (if not why not)
Second thing download mode (which shows in your picture) is for flashing official stock roms.KitKat is not official on the I9300 to flash it you need to use a custom recovery like PhilZ,Cwm,Twrp etc.
To get out of download mode just hold the power button for 10 seconds or pull the battery.
Please read the stickies again and back up your efs before doing anything or you may find yourself with a unusable phone.
already tried switching off and removing battery.
i think i should take it to service center.

So are you saying it is stuck in download mode even when you pull battery or press power button for more than 10 secs?
If so try flashing a stock rom with odin while it is stuck in download mode what exactly was you trying to flash (post a link or full description)
got it fixed ..
took it to customer service :good:
