[Q]

My galaxy note won't stop restarting itself
I tried rooting the phone, unfortunately I used the wrong ROM file and ended up flashing it with the root ROM for the i717 AT&T model. The phone is actually the SHV-E160L model and I tried downloading the E160ROM.
The phone keeps showing the samsung logo, vibrates, and restarts.
Any help would be greatly appreciated.
Put it back into download mode and flash proper stock rom through odin. That should fix bootloop

I don't know which is the proper stock rom I also can't read korean so finding it has been a struggle

Try this. I only skimmed it but it looks like what ya need.

It seems to have worked
Thank you so much, the start screen now has a pink logo instead of the normal samsung splash screen but I don't care
Edit:
My happiness was a bit premature, although the phone now starts up and most things work, the home and return keys do not respond though they light up and attempting to call someone crashes the android core

My GS2 has hard bricked

Hello,
I think I have hard bricked my galaxy s2 GT-I9100 (France)
It was working well with the official Kies ICS update.
I installed Sygic Navigation Trial app from Play Store.
Then I started Sygic. It asked me to select maps to download.
I selected some and started download.
When download reached 1800M over 2400M my phone suddenly stopped working. The screen was freezed.
There was no response either from the home key neither the power button.
I removed the battery.
Now the phone doesn't start anymore. There is nothing on the screen. No samsung logo, no battery indicator. No sound. No vibration.
Could someone please help?
I suggest you send it to samsung service center

The phone had just been charged all night before.

So many SIIs dying due to weird reasons recently, dafuq? Mine died twice already! First time was fixed with a free new battery from sammy but now its dead again...... same reason i think. I let the battery run from 100% to 0% and now its dead Battery dont wanna charge no boot no screens no vibrations... Something is wrong in there...
I still cannot power on my sgs2.
What I have noticed is that when I let the battery in the phone, 10 min after I can feel some heat like if the CPU is working at 800mhz.
I think that the phone is endlessly trying to boot, but resets even before reaching the first samsung logo.
My fear is that the mmc chip is corrupted. I heard there was bugs in the emmc firmware with the wear leveling.

[Q] Startup Issue

Hey all! Im new to xda-developers I decided to post here because I honestly got alot of help from here already. So anyway, here goes....I used ODIN to flash a new firmware onto my GS2(i9100) and all went well..got the green "PASS" box and whatnot.
Shortly after the phone rebooted but here is where my problem starts. The phone is stuck on the "Glowing S" screen (Picture of a large S animating/changin colours and Samsung Galaxy SII written at the bottom)
It has been sitting here for nearly an hour now. I have tried pressing and holding the power button and battery pulls but to no avail.
I can enter ODIN mode (vol - , HOME, POWER) but I cannot get into recovery. Everytime i press (VOL+,HOME,POWER) the green android robot just sits there for maybe 5 secs and then the phone reboots and gets stuck AGAIN >_<
I don't know what to do Its ok if i need to wipe my data etc bcuz i got backups
My concern is getting my phone in working order again and ASAP because I need my phone for my work
If you can get into download mode just re flash the ROM again, the same thing happened to me and this fixed it

I reflashed a million times (ok 7 times really) but same thing
i reallly REALLY dont want to hear my phone is bricked :/ if i cant sort it out i would carry it in to the local store but they gave me an estimated time of 3 weeks because the owner would be out of town :crying:
Probably just needs a factory reset.
Next time list the firmware(s).Thats more important than an owners holiday arrangements.
Similar problem
My phone is stuck after the Samsung galaxy S2 screen. I took it to the service center but no luck. They said I ll have to flush the software privately because it was bought in Singapore (overseas model) and India software doesn't work or change my complete board to an India board. Any idea on how I can go about fixing it ?
get into recovery & clear data/cache

samsung s2 skyrocket bootloop plz help!!!!

Hi,
So my SGS2 Skyrocket is stuck in a boot loop. I've have the Sky Icecream Sandwich ROM installed for a few months now, and haven't changed anything recently.
What is happening is my phone with vibrate every 2-3 seconds with a blank screen. When I take out the battery/power source, and put it back in, the phone shows the Samsung splash (not the Android splash) for a few seconds, then goes blank and does the vibrating again.
I've tried plugging it into the computer, but the power it gets from USB turns it on and into the boot loop, so I can't get it into any kind of recovery mode. I also tried the Vol+Home+Power key combo, with nothing.
Any idea what could cause this/what the course of action should be? Thanks!
The Galaxy S2 and the Galaxy S2 Skyrocket are two completely different phones. This is the forum for the Galaxy S2. Go ask this question in the forum for the Skyrocket.

Hi! This herna from XDA Assist.
Well, normally if you did not touch any deeper thing in your ROM you should have no problem if you have been using it for as much time. Anyway this question should be done in the above thread, so I will move it there so you can get a better reply from people using the same device or even the same ROM than you.
http://forum.xda-developers.com/galaxy-s3/help
I will move it to the original place where it should be, and wish you to get the answer you are waiting for.
Try usb jig to force download mode, if that doesn't work then it sounds like a brick -sorry.

I just dont understand how it could be bricked after being perfectly fine for 2 weeks and i had been using it like 5 minutes before no problem :/
Blame the emmc chip, it is very fragile and can go pop at any moment.
Try reading the dead boot recovery thread in general forum.
