[Q] Galaxy S2 Stuck at logo all of a sudden (not rooted) - Galaxy S II Q&A, Help & Troubleshooting

Hello a couple of days back I had my phone charging over night as usual, however at the morning the phone showed the Samsung Galaxy S2 white text as if the phone was about to boot up but it never did. I have tried removing the battery etc with no luck and I cant get into recovery mode, the only thing I can do is to get into Download Mode.
I have never rooted the phone and it have worked flawless for 2 years.
So I tried to use Odin to flash it with a stock firmware, my phone it not tied to any operator, I have tried 2 different firmwares so far with different versions of Odin and different USB leads with the same result, a ERROR at cache.img, Complete(Write) operation failed.
I have no idea what to do and I´m starting to get worried, what is there left to do :/?
Help will be greatly appreciated!

I have tried to do that with no luck, download mode seems to be the only way.

yes. flash your ( preferred ) stock rom from odin . here are a few links to help you
guide how to flash stock ( in case you did not understand me ) : http://www.ibtimes.co.uk/samsung-galaxys2-i9100-unroot-official-jellybean-firmware-460777
stock roms for i9100 ( jelly bean 4.1.2 ) http://samsung-updates.com/device/?id=GT-I9100

As I wrote Odin is the only way and it is not working, tried multiple different firmwares, PCs and usb leads and I can never get passed the cache.img part where it after some time always comes up with FAILED.

[Q] Messed up with my Samsung Galaxy Ace S5830B

Guys,
I've tried to update my Android's firmware from v2.2.1 to the ICS rom.
The issue started when I've tried to flash CWR through ODIN.
All procedures have been done: loaded the cooper, and the CWR .tar, put my mobile on Download Mode, plugged USB, Odin showed <1> Added!!! <1> Detected!!! and hit the Start button.
After waiting for about 30min there was no response from ODIN, then, I removed the USB and closed ODIN. After that I turned on my Galaxy Ace and the following scenario came up: an image of a pc connected to phone with exclamation mark in between.
Later I tried to recover my mobile by flashing the firmware of v2.3.6 through ODIN as well. It started well, but, in the middle of the installation it failed.
What can I do?
Please, it's urgent!
Thanks in advance folks!
happened with me a lot....but i usually flash the stock firmware with odin and my phone becomes good as new. try again to flash stock firmware via odin.
if i'm not mistaken maclaw's ics needs gb bootloader, thus need to flash stock gb rom beforehand. u cant just go straight from froyo to ics :/
btw try this.
turn off phone, remove battery, wait for around 5-10 seconds, press three button combination for download mode (vol down+home+power) and while u still holding those three buttons reinsert the battery. device should go into download mode and u should be able to reflash with stock gb rom via odin. and good luck with it.

[Q] Need help with unbrick I9100

Hi guys, I have a big request.
First I'm sorry for my english but I'm only 16.
I bought a cheap I9100, it was cheap because it can't boot, it always stops in Samsung Galaxy S2 I9100 logo and never run system.
I search and found on xda forum this thread http://forum.xda-developers.com/showthread.php?t=1449771 but I've got problem. Previous owner of this phone say me that he gave his colleague phone to install new fiirmware and he broke it during install new firmware. He don't know exactly which FW he wanted to install on his phone, earlier he had GB so I think he want to install ICS but I'm not sure. In this thread http://forum.xda-developers.com/showthread.php?t=1449771 is say that I have to use appropriate system files GB or ICS. But I don't know which one I must use because I don't know which one FW (GB or ICS) colleague want to install and i don't want to brick this phone. My question is: Is there any way to check which firmware was install the last on this phone and which files of this guide I have to use ?
Thank you very much for your help !!
Ok first of all u need a USB JIG... Order it from ebay or just check out in local shops.. Thr s only one possibility that he might hav flashed I9100G fW... Or may be some other phone's fw. So U told while booting its stuck at Samsung LOGO? Then it must be samsung fw... Try getting the phone into download mode if not possible u use USB JIG... Then flash thru ODIN... Download the fw from samfirmware.com
Yes, but which one firmware I should flash ? GB or ICS ? In this guide is say that if I will try restore my ICS I9100 with GB files I can brick it, and I don't know which one firmware tried install previous ovner (GB or ICS)
Try Flashing lightening rom from odin.

Also do a full wipe from recovery

Hi, every your solution doesen't work, I can go into download mode but after flash in odin it still hang up on Samsung galaxy s2 i9100 logo ;/
So you've flashed a rom as suggested & you have bootloop ? Boot into recovery mode (volume up/home/power buttons) & do a data wipe/factory reset.
Yes. I can't get into recovery, when I press and hold Vol.up + home + power it turn on and then shut down and again turn on and shut down
Also I haven't a .pit file for ICS version
Keep pressing the buttons, it well go into recovery, sometimes after you See i9100 three times come and go
By the way, what I just read it is not brick.
Its boot looping
Recovery is available in stock ICS ? because 5 mins ago i flashed official LP8 samsung firmware. Am I have to install something special to get recovery or it should work with stock firmware ?
Stock firmware = stock recovery.
Doesen't work I can't get into recovery and no matter which rom I install it stop booting on Samsung galaxy sII logo
I vatched on youtube updating S2 to ICS via ODIN and when the phone boot after updating it skows android, and my phone never show it only stuck on I9100 logo
Now when I press and hold Wol up + home + power it shows empty battery with circle
I still think you have zero issues....
Remove battery
Re insert battery
Plug in the charger
Let battery go close to half
Remove charger
Remove battery
Re insert battery
Keep pressing home + vol up + power until you see green Android
After install custom kernel green android shows on a moment and dissapera, now I have empty battery icon ;/

Recharge your battery. Go to Samfirmware.com and if you haven't already done so, download your latest ICS for your phone.
The Pit.file is a standard file for the I9100 and works from gingerbread to ICS.
Yor can download that from my Dropbox.
http://dl.dropbox.com/u/34590193/Flashprogram Samsung I9100 + Pit.rar
Once your battery has fully charged, if you can get into recovery then do so.
data/factory reset... Advanced.. wipe dalvik cache.... mounts & storage format system.
Turn off phone. remove battery 15 sec. insert battery and boot into download mode.
connect the usb lead to phone and PC. run Odin as Administer.
when odin displays yellow then your ready to go.
Put the pit file in and the firmware in and press start.
If you cant get into recovery then go staight to Odin.

Sometimes download mode can work even if the screen isn't turning on. You should follow the instructions for download mode and see if Odin recognizes your phone.
if see odin has recognized ur fone, flash it with the stock firmware using odin!
Thanks for the response but I tried several times but phone is not booting up in downloading mode.

Try this (it may or may not work)
Launch PC Odin & get rom ready (I recommend LiteningRom [NB, it is custom rom that can be flashed via Odin]
turn ph off & remove battery...
plug ph into pc (NB, battery still out...)
**now you may need extra set of hands here (I managed it by myself though)**
now, hold the button combo to get ph in to d/l mode...
keeping the d/l button combo depressed... put battery back into ph...
hopefully ph will show d/l mode ready on screen & it will be seen by Odin :fingers-crossed:
(if above worked) flash Litening Rom & count your lucky stars...
NB, this saved me when my S2 had BSOD.... i.e. nothing showed on screen after flashing a recommended kernel (by a more experienced user/member - not the OP)
always read up before doing anything kernel/recovery related
Try USB jig.

[Q] Did I brick my phone?

Hello xda, first post n00b here,
I recently got my hands on a SIII (lot better then my old htc one V), and I wanted to install cyanogenmod on it. So I installed the i9300 recovery rom on it and for a short while it seemed to work, but when I tryed to sideload cyanogenmod something went wrong. Everytime I rebooted I got thrown into the downloading, do not power off target!!-screen.
I quickly found my mistake, I did not have an i9300 I had an i9305. With some help from the lovely people at #cyanogenmod (shout out to you PsychoI3ob) I figured out I had to flash the stock rom. I could not figure out how to do this with heimdall, so I downloaded Odin. With Odin, everything went right untill it was somewhere around 99%. The write failed. Now the only thing I see when I but the batteries in my phone is: Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again.
So now I would like to know: Did my phone just become a paperweight or is there still anything I can do?
Thanks a lot for reading trough!
If you can get back into download mode by shutting down your phone, and then boot while holding the volume down, home button and power button simultaneously you could try reflashing stock ROM through Odin.
If the phone turns on as soon as you put the battery in then you will have to take the battery back out, and then whilst pressing Vol Down and Home button put the battery in (I've had the same issue on a Galaxy Ace II with the phone booting as soon as the battery was put in, but managed to get back into download mode and reflash by doing as I described)
If you manage to successfully reflash, boot into recovery (turn off, then hold Vol Up, Home and Power) and do a factory reset from there just for good measure.
Good luck :good:
"Firmware upgrade encountered an issue..." It is also download mode. You can use Odin to flash while this screen has been displayed or launch Kies and restore your original firmware by firmware initialization option from tools menu.
Write model name GT-I9305 and your phone serial number (under battery). Kies will check what version of firmware was originally pre-installed on that device. Will download and flash it automatically. After that you can upgrade to newest stock. Write custom recovery via Odin, flash custom rom from CWM.
