Did you pull out the cable?
Did you pull out the battery? (Won't recommend it, wait till it dies then pull out)
If you did these things allready. Put the battery back, does it do anything? Or does it do anything when you try to recharge? If nothing (or only showing you the battery) you probably need a USB jig.

Hello everyone,
My Galaxy Tab 10.1 GT-P7500 is stuck in a boot loop which only shows "Samsung Galaxy Tab 10.1" on screen. I've tried pressing the power button to power down the device, but the screen will just go blank for a while and then the "Samsung Galaxy Tab 10.1" will show again. There is no way for me to go into download mode.
Any way to solve this problem?
I've tried and tried and finally got into download mode, used Odin to install a kernel. Everything runs OK, until it reboots. Then I see the logo again for awhile, suddenly it powers off, then unable to switch on anymore. I think the battery is dead, will try later after it is charged up.
Nobody seems to care about the issue I've face.
Anyways, been trying out all the solutions that I can find all around XDA, it turns out only "restocking" can solve my problem.
Re-flashed my tablet following the guide at Team Overcome's site.
Maybe these instructions will help
a while ago i got my tablet stuck in bootloop... after a lot of research... i fixed it and put the step by step here: http://forum.xda-developers.com/showthread.php?t=1329261
Let me know if it helps!
You should get a USB jig. It'll jump you into download mode. Unless that tablet doesn't use the mini usb... Which it might not. If you have a custom recovery on there, then wipe data, then install a new ROM

Bootloop and recovery will not work...

Hi - will a "USB jig " help me with my problem, or do you have any Suggestions?
I was flashing stock 4.0.4 ICS via Odin and unfortunately I walked away from my computer for a quick minute ... and my 3 year decided to unplug the tablet. I previously had CWM v.5???? - now I can see the download screen, then get to the OS warning screen.
Then when it says to hit volume up to continue and down to cancel ... I hit volume up and it goes into bootloop and when I hit down it goes into download load but Odin doesn't recognize it.
Note : I have to hit the opposite volume to even get into download mode.
Any ideas or help would be greatly appreciated.
if im not wrong you can restore with kies, emergency firmware ....... or something like that, did you try?
My phone is not restarting. I am using a Samsung Vibrant T959.
I really love the phone since it a gift from my sister and I hope i can fix it. It had no issues, with a stock 2.1 firmware, but last month I installed ICS on my phone after which I started receiving me errors.I guess the ICS version i installed was not very stable. Usually restarting the phone would fix the problems and I would be good to go. However last evening when I got the error I restarted the phone 2 times but I would still receive the errors. The 3rd time I restarted it, the phone got stuck on the animation screen and did not boot.
I tried the recovery mode and it worked fine.
I took a backup of my data using the USB debugging mode of the phone.
Since I was irritated with this version of ICS i tried to root my phone using Odin.
Odin failed. The phone was stuck on the downloading screen for some time so i disconnected the phone from my computer and now the phone will not start.
It does not boot, it does not go the recovery mode nor the download mode. when I press the power button or the three buttons (volumn and power) together the screen shows a mobile phone a computer and a disconnect between the three (Phone ! PC sign).
I do not know how to fix it. Any help on this would be appreciated.

Hello,
I've got a problem with my Galaxy S2 I-91000 unbranded rooted with official ICS rom (but not the one from my country, the Frankenstein one if I remember well). It was working fine for a few weeks and this morning it failed to wake me up... (thanks to my loyal backup alarm clock otherwise I would still be sleeping haha...). It seams the phone juste shut down by itself during night even if plugged to the official wall charger. I've tried to restard it while on the charger and get stuck on the Galaxy logo (the one pulsing with a purple/blu logo). After 10min on that screen I removed the battery and try again without the charger. Now it's getting stuck on the Galaxy SII white text logo (the very first screen on start up).
I've tried up + home + power for recovery mode and other options but after a few second I've kept the three button I've the Galaxy SII screen turning black and then coming back again...
I've tried down + home + power and I get the screen from Odin that ask for loading a custom rom. So I seams my only option, ? I've downloaded a rom to try, I've choose Super Nexus copy the Google Apps + Super Nexus Rom to my formatted SD card and accepte the rom download with odin... and here it get stuck on the screen saying: "Downloading... Do not turn off the target device"... after 30min on this screen I've removed the battery and give it up.
What should I do now ?

Did you try, pulling out the battery -> hold power for 10 seconds -> putt battery in and boot?

Yes one of the first thing I did. However I've tried again and this time it kind of goes further, I get the little intro but laggy then it get stuck on the second logo (purple/blue one) like the very first time I've tried. I'll try the guide to fix unflashable or soft bricked SGII... let's hope.
(In these time I understand the bad side of using Google Auth. for many website )
EDIT:
I've tried the Guide http://forum.xda-developers.com/showthread.php?t=1449771
Flash with code, modem and CSC get stuck on NAND write ....
Flash with . pit: I didn't because I couldn't get a .pit file in the provided archives. I found some on internet but I don't trust them as I don't know what is the purpose of the .pit file.
Flash Kernel: get stuck on NAND write again.
Now I get the yellow triangle with warning about recovery mode in Kies. So I've re-installed Kies again and tried that but I can't use it because it didn't failed during an update from Kies...
Basically I'm stuck with a useless smartphone without doing anything on it that cause the problem directly...
Anyone found a fix?

Exactly the same thing happened with me today! Has anyone found a fix for this yet?
Hello folks,
I've a friend who's not a Technical person, however, he tried what he shouldn't have and now he has a totally dead S2.
The problems:
1. Phone doesn't switch on, nor does it goes to download or recovery mode - I tried it all.
2. When I connect a charger or usb - It does start showing the battery icon and while connected to the cable, if I turn it on it stays at the Samsung logo forever.
3. Since I don't know how to even get it to download mode, I'm unable to go any further.
What he did:
1. Trying to upgrade to JB, I think he messed up with the kernel by uploading one which may not be compatible as I've heard S2 has different variants. (He loaded Siyah 4.2)
2. Before doing this, he had connected to ODIN and was trying to load the official JB file but it always got stuck on one of the steps and that's when his phone got a bit sick - it would show "Please connect to KIES and try a recovery" kind of message. And this led him to do Step 1, which he shouldn't have.
I read a lot of posts, tried a lot of things but the phone never goes to download mode. And I've no clue how to try anything else?
So experts, I need your help here and I want to know if this phone will start at all? Can we somehow get it to work? If not at home, can the people at Samsung flash it or something?
Please help. Lots of thanks already!

if u have any mini usb cable cut it and peel of the skin and short the the 4th and 5th pin with 300k resistor or 100k*3 resistor and connect to mobile u will directly goto the download mode remove this pin and connect pc in odin mode and flash first with ics rom and if it is success and then try jelly bean try good luck
I have the same problem.
Today i tried fixing a bricked galaxy s2(yellow triangle with exclamation mark on boot) by reinstalling the stock firmware with odin and a pit file.
During the install i got stuck at NAND write start.So i took the battery out to get out of download mode and put it back in.When i tried going to download mode,it wouldn't start,charge,boot,anything!it's like it's completly dead.
Is there any other way to go to download mode without using a JIG?

Sorry to say this mate......you shoulda read some threads.....
If you had, you'd have realised.....
1) you start messing with pit files as a LAST resort
2) you NEVER pull a battery during an odin flash
3) when you saw the failure of 'nand write start' there was still the possibility to recover your phone....right up to the point when you pulled the battery.......
So now you have no recovery mode, no download mode and no on screen indication when you plug the charger in.....
Don't bother with the jig.....it's a long shot under the best of circumstances.....
There Is one thing you could try.....
Take the battery out. Press the vol down, power and home keys simultaneously......and WHILE holding the keys.....reinsert the battery....you will probably need help to do it.
It *might* kickstart the phone into download mode.....or.......it might not.
If it fails.....then Samsung warranty repair is realistically your only option.....Don't mention XDA or rooting or custom roms or odin or anything like that. Play dumb....say you were updating with kies, the phone switched off and wouldn't turn on again.......

Thank you so much!! I wasn't able to get a usb jig but managed to get it online with a quick delivery. It was my first time using a usb jig but it's too simple. I've a working phone with JB in it.
Thanks again!

Thanks for you answer!Will a JTAG work?If i can find one?The phone is off the warranty.
The way I see it is that at the moment, you own a paperweight.....so best to *try* the cheaper options first....jtagging being the cheapest......
If that doesn't sort it....you have 2 options.....
1) replace the mainboard
2) buy an entirely new phone.....
Basically whichever option you choose from now on will have *some* financial cost........

A 3rd option is to buy a 2nd hand phone with maybe a cracked screen,and use the board from that.
