Rogers S3 Bricked.

Hello everyone.
I have tried searching a few threads but i have not found the right info i needed. Here is my story. I am also sorry i am new to Android so i have no knowledge of what Rooting & such is.
I bought a S3 from someone on Kijiji. The phone worked fine & he told me he JUST unlocked the device. I said alright & went ahead & bought the phone from him. I came home & looked at the device. The Device Status said " Modified" What does that mean?. I started downloading apps & a app called "SuperUser" wanted permissions to some apps i downloaded. So searched & found it it was rooted because of that app.
After that i downloaded " Rom Manager" seeing as a few people told me to do it to check if it has been trully rooted. ( Bad idea). I did the Factory reset from there & boom the phone just shut off & never came back alive. Did all the reset that everyone said & nothing. Computer wont even see its on or anything. Odin wont show anything either " Thinking he may have rooted it" I tried charging it & nothing. I tried the Vol down, power & home button but nothing will show up. Black screen. When i take the battery out & plug the phone on the charger the red LED comes on but comes off after a few seconds.
Seeing as it may be hardbricked, i contacted Rogers & they are sending me out a replacement S3 for $35. The thing is i want to ask you guys, will they see if it has been truly rooted & such? Rogers tech support agent told me they send it to Samsung & they deal with it & if they see its been rooted i will be charged around $600 for the refurbished device they are sending me. The phone was warranty until Sept 13, 2013.
So all in all, what does "Modified" On the device status mean & will Samsung see if it has been rooted if the phone won't even power on or anything at all? I am just worried that i will have to pay $600 fee for the refurb device.
Thank you for you time & i am sorry if this has been answered somewhere.

Bump for any help. Thanks

What exactly did you do in Rom Manager? Did you flash a recovery from there and say choose the wrong recovery? If so you hard bricked it for sure cause it will have written the recovery to the wrong partition (most likely the bootloader partition). If you did not do that, then need exact info on what you did inside Rom Manager.
MODIFIED on the status only means its rooted, thats all, nothing bad.

BTW to answer your other question, Samsung will probably not be able to tell it was rooted since from your description you clearly hard bricked it to the point where the bootloader was wiped. So Samsung would have to re-write that bootloader which takes JTAG work for them to find out your phone was rooted, I doubt they will do that, plenty of others have been in your situation and Samsung as replaced it without a problem. I dont think their service dept goes to the level of JTAG'ing a device to check if it rooted or check what happened.

Hello Dixit & thank you for the reply.
I opened up Rom Manager & pressed the " Reboot into Recovery" Once i pressed that, the phone just shut off & never came back alive ever again. The person that sold me it STILL says he never rooted the phone. Of course we all know why but anyways. I did all the power trickes like holding down the Vol down, Home & power button & nothing comes up at all.
Before all this happened i did see the Status saying " Modified" That is why i asked about it. Rogers techs told me that Samsung will try & force the phone to wake up or force the software back into the phone. They told me if Samsung find out its been rooted, it will cost $600 for me to pay for the refurb device. Funny thing is Refurb S3 from Telus is at $349.99 yet Rogers claims Samsung will charge $600 for it..
Anyways i am a bit worried as well.

Holding Volume Down + Home + Power won't boot it into Download Mode at all? If it's a firmware issue you'd just need to get to download mode to reflash via ODIN.

Well first off what the previous owner did isnt harmful as it was just rooted and was working fine when you got it. You can easily unroot and clear everything including putting it back to original stock recovery in about 30mins.
Now on your issue, I dont know if Rom Manager attempted to flash a recovery or not, normally just hitting the Reboot into Recovery basically issues a ADB Recovery command that just tells the phone to boot into recovery, that is not harmful in anyway. Looks more like the RomManager flashed a recovery and did so by flashing something that is not for the GS3 which then wiped the bootloader partition and basically hard bricked it.
If you too scared to send it to Samsung, then pay the $50 some dollars it costs to have the JTAG service done by MobiletechVideos

Nope wont help here, the bootloader partition looks like it got wiped out, nothing you can do except JTAG it at this point. If the SAMSUNG doesnt come up or the phone dont vibrate its toast. I had the same issue happen, same results of how just the LED comes on for 5secs and then goes off. Computer wont see anything except QUSB_DLOAD on the Device Manager. Meaning it would only work if someone had the QPST tool files to revive it but to date no one has those files or information.

Ouch.. that's rough..
I was hoping for his sake it was something much simpler.. lol

You should be able to force the phone into download mode with a Jig. Before you do that, I'd recommend doing some research to figure out what you need to do to properly re-image the phone.

And this is why those new to android should really do their research before modding their devices...I suggest every new android user read up on ADB and get that properly setup on their PC...ADB is very handy!!!! I have never once used an app to flash a recovery for a phone as choosing the wrong one can wipe bootlader partitions as seems to be the case here...I use either fast boot or ADB..using this I can double check to make sure I have selected the correct recovery and that it will flash to the proper partition...to the OP chances are Samsung won't go far as performing a JTAG in which case they won't see the phone is rooted and will just send you out a new phone...if you'd rather not deal with Samsung get in touch with mobiletechvideos and pay for the JTAG as another user has recommended.. its actually a great service as it makes your device essentially brick proof after the JTAG mod.

Thank you everyone for your help. The guy would owned it first still denies he did anything to it. I am waitinf for Rogers to send me a refurb S3 and I'm sending my back to them.
Also I never knew what to do with ROM MANAGER. I am new to thi stuff and I am sorry I did not read all about this before. I was to happy enjoying the phone and all.... I won't be rooting my other one seeing as I do NOT know how to root and such. I do not want to ruin this one. Also when I went into Rom Mer I pressed " reboot to recovery" that's how the phone stopped working. I have no idea what the other person did on it.

Btw whether he did anything to it or not, it's not his fault that your phone bricked. There's nothing he could've done that would brick your phone just by going into recovery.

I fully understand that BUT he could have been honest by saying that he did root it. He knew I never knew anything about rooting and such. So he never admitted he did. Oh well. Lesson learned. Never believe anyone.

Odin a stock rogers firmware thats all you gotta do bud it would unroot your device and allow you to get past that screen. and then you can reroot if you want to

my phone doesn't charge/boot... probably dead

i already searched a lot, but i didn't find anything useful so i post here hoping that someone can help me. i really need my phone so before send it to htc service i have to try to get it back working.
simply yesterday my phone went off because of low battery. when i got back home i try to charge it, but nothing happened. so i tried using pc in order to see if something happen, and led started to blink slow (orange led). so i turned it on, and it worked. then i was using it (connected to the wall charger) and it frozed, at 9% battery. so i tried to restart it (by pressing power and vol down), but nothing happened... it was completely dead, i tried:
-wall-charger;
-pc-usb;
-change different charger/different usb cables);
-i left it the night connected to the charger);
-no adb, and obviously i can't get the phone in recovery/bootloader/fastboot...
i was on hboot 1.3x... don't remember which number cause i updated the hboot a few days ago. i was on viper rom and i was using the tripndroid kernel based on official nvidia sources (really like their works )
hoping that someone can help me
however in the next days i will send it back to htc but i need to try something cause i really need my phone in those days and i have no replacement. will htc repair my phone for free? (remember that i unlocked it)

Crazy thing. U can't put the phone in bootloader mod?

no i can't...
completely dead, i think i should just stop trying to fix it

That means your phone is broken. It needs a new motherboard.
Nobody has recovered from that. Some people have managed to get the phone working after APX, but it seems to go back to APX mode.
Sorry. Back to HTC it goes...

ok thanks... it is and hardware fault or it's because of the custom rom/kernel?

Hm, you can use download mode as long as the SBL is booting (as you can see by the boot logo)...
Maybe try factory mode (usb jig)?

Yeah, I've ordered a USB jig, so I'll try that when it comes if I don't find a solution before..
I can't get it to boot into download mode or recovery, so I don't know how I'd be able to flash with Odin..
I have been able to get odin to recognize it once in a while by messing around with different 3 button combinations, but when I press start on Odin, it just sits at "setup connection"

Hard bricked, send back to Samsung and play dumb or see if one of those "we unlock all phones - international sim cards - cheap accessories" places can reflash it with JTAG

I've quicky googled them a month ago and they appear to be about 70 € IIRC, and if you're serious about them remember that having a complete dump of the exact phone you have will make it 100% unbrickable

By unbrickable you mean that I'll always be able to reflash it and revive it? Or that it won't be able to be bricked again? And I noticed many different jtag systems on eBay, which one would you suggest that I get?

Oh, the first
Basically, since you can read and write all the flash through it, just create a full dump when it's working and restore it when you hardbrick or... uh, get no display in recovery and want to fix it quickly :laugh: (for anything else flashing with Odin is probably quicker)
From what I've read RIFFBox is one of the most popular ones https://www.youtube.com/watch?v=5TTjZgQYRfw, it's probably a little overpriced for what it is but it's aimed at the "professional" market of those independent service shops...

[Q] [Help] Phone tried to update now bricked

I seem to be having tons of problems with this new phone =( HTCdev unlock failed work and now the phone has bricked while trying to do an update.
It is stuck on the "HTC powered by android" splash screen. The screen wont turn off and the phone does not change. Is there some way to fix this or am I farked? The phone is literally 3 days old and I hope there is a way to save it.
I can shut it down with Power and vol+ but when it restarts it just locks up. computer does not recognize it though it did install some form of driver.

I would return it

Since I cant do anything until Monday I decided to mess with the phone a little more, I was able to get a custom recovery installed finally so hopefully all I need to do is install a new rom but the problem is the recovery is unable to mount my SD card to perform the install. I can read the sd card when it is in my old phone but not on the HTC One. Currently have Philz Touch installed as the recovery.
Is there any way to fix this or even bypass it all together?
Edit: I have been able to side load CM11 Nightly onto the phone so now it is functioning. I am having an issue with sound though so hopefully I can fix that.

Warranty returns are for manufacturing defects, not botched mods done by the owner. The phone is completely recoverable.

User error. The phone wasn't bricked (if the screen comes on, its not bricked) and 99% of the time when folks here say the phone is bricked, its just not booting. As you can see from his subsequent post, he was obviously able to get bootloader unlocked, custom recovery and custom ROM. Of course, you could have not known that when you made your previous post. But failed bootloader unlock, and then the phone won't boot, is a big red flag that the user just did something wrong.

Naw, really looks more like a matter of the OP needs being clear enough, and not giving enough info. If anything, best to get clarification before suggesting warranty service (especially once mods have been started - but again it was hard from the OP's description to know how far it got). Although if it was in fact a hardware defect, of course a warranty claim is valid.

Hi there,
I've been exactly there with my H815. I have tried numerous solutions, but to no avail. On your reddit post I saw that you tried the recovery key combination and ended up in download mode again? Did this happen, after you pressed a button? With my phone, when the LG factory reset screen appeared and I confirmed twice, a long time nothing happened. After a couple of minutes the Android recovery (not TWRP) screen appeared. Maybe you'll have a chance to get your phone recognized via adb sideload or sth. Or start fastboot mode. Maybe you can reflash TWRP? But if you are facing the same problems as me, it probably won't help you.
For me, I ended up sending my phone to LG, despite the fact that the warranty was void. They changed the mainboard and never said anything about repair fees and apparently the phone is on it's way back to me as I write. I hope it arrives tomorrow and I can let you know.
Hang in there! :fingers-crossed:

My warranty is over ( 2 Years ) Do you think I could try ?? (Bootloader unlocked/ Custom rom and recovery have been installed)
But I can access to the LG recovery if you mean the one with Restore factory with double Yes ? But when I press Yes my phone freeze like 15 seconds and reboot in download mode...

I cannot give you any guarantees, as I am not associated with any LG support haha. Technically, I am still on warranty, but as I also unlocked the bootloader, installed Custom ROMs etc... the warranty would be void anyway.
I got a reply from LG support that i should send it to their repair shop (some shop in Germany) and they would reply with an estimate of the repair costs. Now, all I got is the tracking number, the phone's on its way home and they did not charge me at all (as of yet). So you could be lucky, but you very well may not be.
I'd say, take your chances and contact LG support, send it in. If they want to charge you a huge amount of money, they can still send it back to you unrepaired and you might be able to fix it yourself. In any case, I wish you the best of luck!

the thing is after you have flashed TWRP you HAVE to boot directly to TWRP afterwards. otherwise it gets overwritten.
You can also setup SALT and depending on what your current firmware is you can flash TWRP with SALT too.
For that IRC is much better though http://webchat.freenode.net/?channels=carbonfusion-user

No problem dude! I'll give an update, whether LG's charging me or not
Good luck

check the battery first then try to flash as quick as you can remember you may hard brick your device do it your own risk

Hi,
A belated little update. My phone has found its way back to me and is working perfectly again. The main board had some dysfunction, it was exchanged.
LG didn't charge me a dime, so I can't complain. Flashed LOS 14.1 just now and everything is running smoothly. Hope you had some luck with your phone as well?
Cheers

Ok I tried everything with salt, with the motherboard ! Last thing I can do is to contact the support ... Waiting their answer and i'll tell you the feedback
