The phone would have restarted on its own after flashing. y did u pull out battery when it was written do not disconnect target?
1st of all, you did not have proper files i suppose, always read complete history on whatever u do with ur phone.
Now u have probably corrupted the eMMC chip which means the motherboard should be replaced.
even a Jig can not help u in this case. the best solution will be, if its still in warranty, get it replaced.

No.The screen won't turn un.I went to a service now and they said that it can be fixed with a JTAG,because i maight have damaged the boot.They never heard of usb jig.Can you please tell me how to fix it without ther help ? because they want me to pay 30 dollars.

If you cant afford 30 dollars I would recommend you get a job or ask Mom for more pocket money.
Alternatively read the other threads here that already discuss this type of exact subject and save yourself some time waiting for answers.

if its not showing any life of power, then jtag is of no use. but since they told u it can be done in $30, then u should go for it.
$30 is worth it, u cant jtag urself, its a tough process. u can check out 'mobiletechvideos' on youtube. they hav showed jtag procedure, which requires microsoldering. & a riffbox/similar jtag device (which is again costly).

From what I understand if in fact your bootloader is corrupt there is a JTAG method for recovery but requires opening the handset itself. Same thing happend to me and im having to get it send in. There are a few places that do it for cheap in the states.

Galaxy s2 Bricked

hello experts
i had followed steps to root my galaxy s2 using odin flashing and it was success, and unlocked.
The phone started well with a yellow Exclamation.
and the phone was unlocked.
after a few minutes the phone was very slow and got stuck. i restarted it.
again stuck, restarted but it dint start again. i thought battry was low and put to charge.
but it dint charge as well.
So i showed the phone to a repairing center and they said its dead.
Any help that i can start my phone again ??
Thanks in advance guys :'(
Try reverting back to the stock unrooted rom.
Go to Sam firmware.com and download the stock from ..flash it via Odin.. search ..google is ur friend..Don't ask the repairing shop again for advice (phone is dead...duh)

If you have an official stock ROM with official firmware on it, the repair centre should change your mainboard and basically making your phone brand new.

which version were you on? Are you sure the rooting went okay?
The USB-Jig must work. especially on GB. it even works fot me on ICS.
When you can not get into download-mode (odin mode) ór recovery you can't flash anything..
Hope for you that your battery is broke. or maybe one of the processors... Still got warrenty?

Hi you cant do anything unless you have download mode on you device,
if you have JTAG box you can repair your device using this.
Its normal device getting heat near charging/USB component. This is not HW problem.

[A] Galaxy s2 bricked
You have to know smthng:
- It is always possible to get to download mode, if not through the button combo (home+power+Volume_DOWN), then through the USB Jig
- If your phone is bricked, the download mode might not announce itself through the android robot: the exclamation mark will persist in some cases. One indication is that ODIN will be recognizing your phone on the COM port (USB that is).
Notify me if you needed further assistance
Which instructions did you follow?
If those are wrong hopefully somebody else will see this and avoid those instructions.

XDA GENIUSES PLEASE HELP! Hard Bricked i9100

Hey guys.
I made a stupid error last night when I tried going from ICS CM9 back to ICS STOCK LPQ.
I forgot to wipe data and just wiped cache and dalvik cache.
The connection broke whilst flashing through ODIN and now I have a blank black screen and the phone won't turn on...((( (It does technically as when I try pressing the on button later on the phone would get hot - meaning its on but BLACK SCREEN)
I have tried taking the battery out for hours and putting it back in...nothing is working.
I don't know what to do...I'm in uni where I have fast wifi. Please help. Any advice would be grateful
EDIT:
Ok.
So usb jig arrived this morning. Ripped it open. Popped my sgsII from charger (fully charged I think!) took battery out - 15 secs
placed battery back in.
Inserted USBJIG. . .
. . .
. . . . BLACK SCREEN OF DEATH
Nothing....Still the same. No screen activity...sad...
only way is either JTAG or Samsung service center right?
I used to have yellow exclamation mark + 4 counts....but they can't see anything so they won't know right?
or did the usbJig work but just the fact that I can't see anything on the screen??
...sad I hated seeing noobs flashing phones improperly and crying when it got softbricked....well even though mine is a straight hardbrick i still feel sad....noob
update.
I've taken it to SSCentre on tuesday. I called them yesterday and they said they couldn't fix it over there and had it shipped somewhere else...is that bad?
it could take upto 2 weeks!!!!!!
I rememeber the engineers working on my friends Galaxy S last year and they didn't have to send it to somewhere else. (he had the soft brick 3 yellow logo icons) and didn't have the version where the download/recovery mode didn't work) The engineer just flashed it with latest stock sgs firmware (ignoring that csc was orange lol)
Maybe my flash was so impeccable I fried the motherboard? I'm one kick ass bricker....

If you can get into download mode then there is still hope. If you can't then your only option is either warranty repair of Jtag service. If download mode then works then just reflash using Odin.

To OP: Yup nothing to do, but send it in for repairs.
yeah sorry not JVU LPQ (I was getting mixed up with firmwares)
Yeah phone not going into download or recovery mode.
I think when I press the power button the phone does turn on but I get nothing but black screen....(the phone warms up)
So shall I order a JTAG to flash? or take it to repair centre?
Will they know I've been flashing this thing to death? Counter is on 4 at the moment..... so worried!

JTag is not Samsung warranty its a paid for service .

.
Warranty is void with custom rom root or rom counter above zero .
Will they know yes counter is on 4 .
Will they ignore it and put it through as warranty they may but dont count on it .
USB jig would be the starting point .
That fails you could go to warranty repair if thats rejected then pay for JTag repair .

if you have adb maybe you could try:
1. Connecting your device to PC while turned off,
2. CMD > adb devices
* If you see your device connected, proceed with:
adb reboot recovery or adb reboot bootloader
* If you don't see any device connected, try googling for qhsusb_dload driver for your device, and after you install them (and maybe a couple of PC restarts) repeat step 2
3. if you manage to get to recovery, i hope you have your nandroid backup so you could restore them.
my HTC sensation 4G had this situation few days ago, couldn't go to recovery/bootloader, blanked out when turned on and had fever
i fixed it using those steps, i wish i could remember where i got the qhsusb driver thingy from.. i'll let you know when i remember.
edit: it might work on S2, or might not.. i don't know this will help or not, but you could read adb/fastboot/bootloader/android 101, maybe you could get something from there

The bootloader death thing is not 100% true. When I first got my phone, (when there wasn't any rom for it) I tried flashing a I9000 rom. I was so stupid and luckily it didn't break my phone. After the flashing it turned on and stayed on bootlogo.
It was a miracle for me!

[Q] i9100 won't start at all

I need some help, a few days ago y flashed SlimSaber on my phone, everything was ok until this morning, when i woke up the phone was off, when i truned on it got stuck on the samsung logo screen, then i tried to start it in Download mode, connected to the pc opened ODIN and tried to flash a stock rom, for some reason the phone got disconected in the middle of that, after that i tried again and this time it finished but said FAIL then i unplugged the phone tried to restart it but nothing happened now i can´t even get to download mode the phone is just there i can't turn it on and i don't know what to do, i need help plz
If the phone won't boot at all, what exactly do you expect anyone here to suggest ? No Christmas miracle.
Service centre for motherboard replacement (expensive option) or source 2nd hand board from 'donor' phone (search online) & either replace yourself or pay a local mobile repair shop to do it (cheaper option).

Try to use JIG, but you don't assure you nothing. The assistance will find out for sure that you have installed a cooked ROM and you will pay a lot for a simple replacement. And then I advise you to follow the many guides available online to disassemble and reassemble the pieces of the Galaxy S2. Let me know
thanks for the help but at this point I think i'll buy another celphone I'm thinking on the galaxy grand or the galaxy win

Sam S10 bricked when PC switched off while flashing by Odin

Hi guys,
I was flashing my S10 by Odin, using USB-C connector which is also charging the laptop.. (why didnt use the second one I idiot??)
Odin sudently stoped flashing, stuck maybe on 90% and I was waiting more then hour, but flashing did not succesful, if laptop discharged the battery and switched off.
Samsung is totaly dead, I tried everything like get to recovery mode, Odin mode, leave the battery fully discharged, unplug and replug battery... No any sign of life. PC doesn't see it..
It seems there is nothing I can do for unbrick it, but maybe YOU know some trick that may rescue my phone...?
Is it possible that some box as Octoplus or some like that will be working for my problem?
Many thanks for any idea, Regards, Tomas.
I would recommend trying to return to manufacturing (RMA) the phone just explain that it's hardware bricked doesn't turn on etc and you should get a new phone. How ever if they find out that you tried to flash custom software on your phone your warranty is voided and you might have to buy a new phone.
download official firmware and flash every file except for HOME CSC using Odin. This should revert you back to stock rom and allow you to boot properly.
It's not normal that flashing takes so long in first place.
Something already went wrong while it was still flashing.
My S10 flashes in like 10 minutes completely.
That's strange anyway because mine stopped one or two times flashing
causing a soft brick but I always could enter Download Mode again and reflash.
I'd basically never flash with a notebook not connected to a charger
but in your case I think you could wait even more hours and nothing would happen anymore.
One exception could be that you flashed the wrong firmware.
I wouldn't send it to Samsung if that's the case (in my opinion).
Just don't do such stuff if you don't know what you are doing and learn from it.
A honest option is to aquire a device with broken display and ideally broken back glass and change the motherboard.
It's not that difficult and you could exchange the battery e.g.. (plus it's fun)
Thanks for all answers.
Unfortunately, the rom I flashet was stock and 100% right for my phone. Downloaded from sammobile.
Also now I'm not able to flash anything because PC does not see my phone when connected...not any sound and Odin wont show that device is connected.
One more information-I'm not some fish to do something what I dont know about..my job is technician in mobile phone repair servis and shop. But 99% repairs I'm doing is hardware repair- like broken LCD change, battery change, charging connector repair by soldering... Sometimes software repair of course, I flashed by Odin many many times, but flashing takes max 10 minutes.. this is why used charging port co connect the phone. There was some another problem I'm sure.
Anyway thanks for your answers.
I'll send the bricked phone on eBay, maybe somebody have the right tool to make it done.
Thx again.
