[Q] Bootloop and Download access fail - Galaxy S III Q&A, Help & Troubleshooting

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] Bricked S5830, please help me

Hi all,
I have looked for a similar post, I found out that many people experienced something like that trying unlocking their phones, but I haven't found out any solution.
Here is my situation:
I have tried to unlock my s5830 (orange spain carrier), I have used a method which it seems to be dangerous for the phone, but of course I have found out it was dangerous after I have already tried it
Anyway after I discovered the unlock number contained in the perso.txt file in the efs folder, my phone restarted without service once and after that it went in a bootloop mode, it goes on a download mode, but there is no way to get back recovery mode or a normal boot.
I flashed the s5830 several times with many firmware, but no one worked, and the phone is still stuck in an infinite loop, in which I am not even able to see the samsung logo coming out at the very beginning.
I know many phones got bricked in this way, I wanted to know if anybody has been able to recover the phone or if anybody know any possible solution.
And if not, do you know if the warranty is covering this problem? I just got the phone a couple months ago; i have unlocked other devices before, but this is the first time I have experienced a problem so I am quite new about warranty as well. Please HELP ME
Merry Christmas guys!!!
Thanks in advance

with the cellphone off, put out ur baterry for a minute, then maintain ur finger into the volume down button and the power button tell a friend or if u can alone insert the batery while quickly pressing volume down and power button to get into download mode, and flash.
Hehehe,bootloop is horrible,you just have to get in download mode & flash with 2.3.4 firmware with Odin,just that steps and you save your SGA.
I got bootloop many times and Odin saved me.

he cant go back in recovery mod............
If you can go to recovery mode than you can just wipe the data and cache. This saved me many times. Otherwise on what ever OS you may be , just create new user name after removing samsung android drivers. Login from new user name and than re install drivers again and now flash your phone from firmware which was installed on your phone before you bricked it. This helped me a few times.

It seems that you've already received a lot of help for unbricking your device. So I'll try to help out in unlocking your phone after you finished unbricking it.
This is the method I personally used on my locked Ace:

thank you very much I will follow your advice...IF I will be able to get my phone back which seems impossible =(
@dr_vishal
Thank you first of all, I have tried to uninstall and reinstall the android device driver, but it doesn't seems to be the problem, Odin ends with a "PASS" at the end, I guess there still is comunication in the between the two devices...
Hopefully it will be a Merry Christmas =)
It's not impossible. I'm relatively new here but I have noticed quite a few "bricked" threads already. Most of them (if not all) have been able to fix their device. I haven't seen a single person permanently brick their device, so I would guess that your chances of fixing it are really high. Just be patient and keep describing your situation and more experienced help will certainly arrive. I'd really like to help out but I have no idea how to fix it as I have not experienced bricking my phone yet.
Anyway, if the method for unlocking I suggested works for you kindly press the Thanks Button. Merry Christmas!

Guys,
I am out of ideas, I have tried each single firmware I have seen around internet, no one is working, any tip or advice or suggestion?
I messed up with the efs, and I guess that's all, the phone is gone....now it needs a JTAG or whatever is its name....
maybe to get the warranty still valid I should broke totally the phone over charging it....??

http://forum.xda-developers.com/showthread.php?t=1153310
just a thought
a lot of people have talked about reflashing it and all but have you managed to get into the recovery mode at all once you have reinstalled the rom with odin? if you can get to that you just need to hit factory reset, wipe cache and wipe dalvik and normaly after that it will work fine... so far ive been stuck in soft brink 3 times and each time doing the wipes from the recovery mode has worked...

I've tried to use the oneclick, but it seems it doesn't recognize the phone, since, i guess, it's made for a galaxy s.
The others are not my case, since I am able to get download mode, and all these are made to can get it back.
Anyway I found out a post in which the people were talking about the s5500, which apparentely is similiar to my device, and the owners of that model experienced a similar problem doing the same process....anyway in that post the people needed to use a Jtag, which is the only way to get it back....so I though it could be the same solution for my problem...but I don't know anybody with Jtag, so the only way is contacting the service center.
thanks anyway, when I will be back at home after Christmas I will try to find the ticket and I will probably try to get it back in warranty, since is preatty new...
@torchwolfery
I am not able to reach recovery mode, there is no way to get it back, even flashing the phone with different firmwares, all I got is download mode, and apparently that is completely pointless...since the only change in the phone behavior is that if i install a certain firmwares it doesn't even have the back-light working when it is stuck in bootloop.
Warranty is your only hope (as it was mine once and it worked).
I didn't think it was possible to brick these phones. There I have tried so much to try and brick it but I have not been able to as it still always goes into 'download' mode. The only advice I can give you is double check that you are using the correct version of Odin which is v4.38 and that you use cooper v1.0 as your OPS. If dont mind me asking, but exactly what did you do or do you remember the steps you took to brick it? What buttons are you using for 'recovery' mode.
Also please clarify if Odin is going in a loop or does the phone come on and then keeps rebooting? If it is the phone that keeps rebooting, then wiping cache and data partition should do the trick. This can be done by going into recovery mode (which I am aware you cannot get into) or if you can manage to get into the dialler quick enough before the reboot, by dialling *7267*3855# and that should format the relevant partitions (data and cahce) and bring it back to factory settings. Without further info, I cannot really tell exactly what the situation is.
The fact that you are getting 'download' mode, I dont think that it is bricked because it will still allow you to write the relevant directory/files to the relevant blocks. Either way, would be interested to know.

Serious Problem with Galaxy S2

I own a Galaxy S2 for AT&T. I had rooted it, installed Clockwork Mod Recovery and CM7 without any problems. I found an article from CNET about a ICS Rom download. I'm sorry I cannot post the link as I am a new user and the forum rules do not allow me to. The article is called "Samsung Galaxy S2 Ice Cream Sandwich how-to guide" on CNET UK.
And I was interesting in trying this new ROM. So I made a back up using the CM Recovery, downloaded the file, and flashed the ROM per the directions. It flashed without any problem and booted right up into ICS. At first glance, everything was alright, with the exception of a few bugs. I noticed the touch buttons did not work, except for the home button. Then I noticed that the phone functions did not work. So I attempted to reboot into recovery only to discover it was gone, along with my backups I had made. Now, I can't even get the phone into download mode (volume buttons + power). Also, the phone is seemingly unrooted now. I fear I have bricked it. I'm sorry if this was in another post, but I'm in panic mode now. Can my phone be fixed? Thank you for any help you can provide.
Try download mode again (volume down/power/home button, release power button the moment the device switches on still holding the other two). You say the phone is unrooted, does this mean the phone actually works, but you can't get into recovery or download mode ? If this is the case, there's no way in the world you can't get into download mode. I've never heard of an otherwise working phone unable to get into download mode (broken recovery I believe tho, that does happen sometimes).
If your phone doesn't work & you really can't get into download mode, you can try a jig (search for Samsung Galaxy S2 jig on eBay), but that's probably unlikely to work to be honest (but still worth a try).
Your next options would be a JTAG repair (search on here) which would probably be cheaper than sending it to Samsung which is your other option.
Also, you've got an AT&T Galaxy S2, which means if you're in the US, you either have an SGH-I777, or an SGH-I727, which is the Skyrocket. (LTE version of GS2)
The instructions you followed are from the UK, which means they were for the GT-I9100, which is the international version of the GS2.
Check under your battery. It will have your model number on the label.
If you have an SGH-I777, you need to be here.
If you have an SGH-I727, you need to be here.
You will probably find better advice in your appropriate forum to get your device working again. Not that MistahBungle doesn't offer good advice - he does! Just want you to have the correct information for your device.
Good point Ctomgee Looks like I read everything but the first sentence of the OP.
First off, thank you for the advice. I greatly appreciate it. Okay, I was using this forum post: "[GUIDE] Fix an unflashable or soft bricked GSII" and in it, it mentions getting to download mode the incorrect way, which explains why I could not get into download mode.
I followed the instructions in the post to the letter, flashed everything and according to Odin, it was successful. The phone booted up and what I see is what appears to be the stock OS. However, the phone functions still will not work and the soft keys on the bottom are also "screwy" (i.e. only the home button works). Are there any ways to revert my GS2 to stock, as in when I first bought it, so I can start completely over, like from a clean slate? I'm just so confused right now, I thought I had a handle on this stuff, but I guess not. I'm worried I messed up my phone for good.
Also, when I hit the power button, there is no option to reboot the phone, only shut off.
That's because you've obviously flashed incorrect firmware for your phone. We have no idea on this forum whether you've bricked your phone or not because we all have either I9100's or I9100T's, so we can't help you.
I suggest you ask in the appropriate Q&A section relating to your phone (Ctomgee gave you links in his post). If you have the 3G version, use the 1st link. If you have the 46/LTE version, use the 2nd link.
Ok, my apologies. I have moved this to the appropriate forum. Thanks again.
NP & good luck. Hope you get it sorted/your phone working as it should again.

Samsung Galaxy S Vibrant T959 totally bricked.

Please Help me out.
I was using CynogenMod7 ROM. Could not write on my external SD card or mount it .
So decided to go back to Stock froyo firmware.
Tried ODIN to flash to my stock froyo firmware.
Had done it many many many a times earlier with success.
But ODIN could'nt complete the process, it kept on getting struck at Kernel and Factory some times.
Later thought there might be something wrong with bootloader.
Downloaded stock froyo bootloader.
Tried to ODIN the bootloader and got Struck at SBL many times ,Kept on trying then got struck at PARAM.
Removed the battery.
From than on NO Response what so ever combination buttons used.
No battery indicators,No light on Home keys, No signs of any power. Nothing Visible on screen & keys.
Tried usb JIG - no response.
Tried Ultimate UnBrick Resurrector-No response.
No lights .
Please solve my problem.
This may not work because I discovered this by accident. I bricked my phone so bad it looked like it wouldn't even turn on too. So, hopefully this works. Make sure you have your samsung drivers installed. Open Odin and connect the USB to the computer but not to the phone. Do a battery pull and do the three button boot, simultaneously connecting the USB to the phone. Most likely, nothing will happen. Hopefully, the phone will connect to Odin. Then, click start. That's right. Don't put any pit or tar files in, just click start. Hopefully, your phone will reboot to the vibrant screen and is stuck there. If it does, now you can reboot to download mode and Odin whatever files you wanted. If it doesn't work, just keep messing with the three button boot. I apologize for wasted time if it doesn't work. These steps are what I personally did on my phone. Hopefully, it works for you.
Sorry to say but I believe you have hard bricked your phone. If installing bootloaders goes wrong then your phone can turn into a paper weight. You could maybe try a jtag repair but I'm not sure it would help. You could call samsung and ask for a replacement, tell them you updated with kies or something but that's not exactly the truth

OK first, the stock images are 2.1 eclair not 2.2 froyo. Are you sure you have the right files? Are you sure your phone is a t959(3g, no front camera)and not t959v(4g, has front camera). Second, it sounds like a hard brick, if all else fails go to www.mobiletechvideos.com and check out the unbrickable mod and JTAG repair.
If you get your phone in DL mode and you have the correct Odin images, check the repartition box as well as others and run it.
Good luck

Remove battery and sim and microsd. Leave out and press and hold power for 30 seconds or so. Leave battery out for a few minutes.
Put battery in and if you are on GB bootloader hold volume up and plug in USB. Might get you to download mode.
I did that with a friends phone about a year ago and got lucky. Odin recognized it. I read that somewhere here on XDA. May be a shot in the dark... but when you get desperate any new ideas to try can be a relief right?
Good luck to you.
After I messed with bootloaders and then tried to get back to stock with Kies I had this problem.

I called Samsung and told them that I was just trying to upgrade to 2.2 with their software and they replaced my PCB (printed circuit board) for no cost (including shipping). I have no idea if they tried to figure out if I had really used Kies (if they could even figure it out with the state my phone was in) or if they just replaced the PCB blindly. Worth a shot, I'd say!
Thanks for your concern.

Please Help
When you pulled the battery, after it hung up with Odin, you corrupted the primary Bootloader, because it wasn't completely written in......Last weak possible option is to try every rocker/battery/cable sequence ETC, to get Odin to handshake with the phone!!.....If there's still no sign of life after doing that....Your only option will be to have it JTAG,d in order to rewrite the primary bootloader file back in it.....it'll never power on unless the primary bootloader executes properly!!....you can corrupt the 2ndary BL and the phone will only be soft bricked, but a primary BL corruption is phone DEATH!!....Only place I know of that's reliable is: mobiletechvideos.com....send it to them, they'll rewrite the primary BL back in it and I think 2.1 or 2.2 for you and mail the phone back to you!!....Good luck let us know if you got it powered on with any combination, as that could save another Bricker from having to send it out!!

[Q] SIII GT-I9305 Stuck in download mode after root

Hey everyone, I just tried to root my Samsung Galaxy S3 GT-I9305 and I believe that I used the wrong rom (for I9300). Ever since I rooted it I can't use the phone, whenever I turn it on it just goes straight to the "Downloading... Do not turn off target!!". I can't exit download mode (tried pressing volume up+power+home) All I can do is re-enter download mode by pressing volume down+power+home. Please help! What should I do? I don't know where to start and I really hope I haven't turned my precious into an expensive doorstop.

First you posted on the wrong forum the I9305 has a separate Q & A thread. Onto though your problem though... your phone is on a semi-brick state since it can still boot into download mode so there's still hope... what I can recommend you to do is that you flash a stock rom this time make sure its for the I9305 branch and not the I9300 one just go to Sammobile and search. If that still fails then better wait for a more experienced user to give you a possible fix as i don't own an I9305 one.
It seems hard to find the stock rom on sammobile for the I9305, I'm aware I'm a complete noob when it comes to this stuff but usually I'm pretty good at finding these things... Has anyone got a link to it?

You should've just posted the link of the firmware section of Sammobile and not copy paste it as a whole... look it's all messy and much more confusing.

I was in a similar situation to our unfortunate friend, biggyjurss. I nearly gave up all hope of ever restoring my phone (SIII GT-19305) to the way it was. I really didn't think there was any way back from being stuck in the download screen that will still haunt me the rest of my days. With everyone's help, I managed to restore everything to the way it was!!!! **** YEEEAAHH! I have learnt a valuable lesson in not to EVER attempt rooting a phone again unless I really know what I am doing and I have done my research. I want to thank everyone on this thread for helping me out!
i'm having this exact same problem after doing the exact same mistakes and nothing seems to be helping. I've already wiped everything from the phone and tried Kies to getting the phone back to stock, but Kies just crashes in the process. I can also get to the boot menu and to the download menu, but nothing helps. The phone just keeps coming back to the downloading screen. Please help :crying: I thought there would be no trouble with rooting your phone since every site just said how easy it is...
THANK YOU!
I made the same error (flashed i9300 instead of i9305), and got stuck too.
Tried flashing the rooted i9305 to no avail.
Had to cross my fingers hoping that my laptop's BSOD doesn't come when I was downloading the stock off Sammobile. (I get intermittent BSODs, usually because of the heat. My laptop is old.)
It's now working again after flashing the stock firmware.
Thank you all, once again!

[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

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:
