boot to recovery,wipe cache and factory reset.
EDIT:Hold "home+volume up+power" all at the same time until recovery menu appears.

reflash with odin some stock firmware if you don't want to wipe, if there is no problem with wiping, just go to recovery and do a factory reset...this has a strong chance of success.

dont bother wit finding of exact fw. for you, find something that is for your region....

Is it flash it by using odin?

apsolutley with odin, since I suppose that you don't have cwm packed rom on SD card, because in that case does not matter if you have cwm recovery or not..., dont know if you have done it before...bat after beginners fear, it is actually peace of cake...dont be afraid, just follow instructions to the letter...

After I flashed it, it turns to the CWM screen and install the Multi-csc..something like that..and it reboot..after it reboot..its still turns to CWM and install the multi-csc.
So what should I do now?

you have done something wrong, or taken wrong rom image, since after flashing with ODIN stock rom you WILL ENDUP with stock recovery! Dont know what you flashed, but it was not stock rom.
What rom you took exactly??

"GT-I9100_SIN_I9100DXKI2_I9100OLCKH1_I9100DXKI1"
I flash this..is this a boot loop or other problem?

Hey dude, thanks for helping me so much..
My phone is working now..but I have to download my things again..=(
Alright. Thanks!

no problem, been in that situation. check some custom roms when u have time....you'll be amazed what this device can do.
and in clockwork recovery you have backup and restore, setup phone just how you like it, make a CWM backup and you are always sure that rescue is there....don't need odin or PC for that.
Flash Supercore with odin as PDA or some other kernel that has CWM recovery

The problem occured again just now, its after i dpwnlpad some apps from market..and its still not completely remove the hanging problem..And my laptop died. LOL.

Anyone here?

May i sugest u reflash stock rom and return it to the store.
If u have random reboot after flashing stock rom there is obviouse something wrong with your device.

hi

wel u have a soft brick ma8 dont panic just dwnl a odin flashable stock GB rom and install the same
after that search the forum under samsung gs2 how 2 root ur phone with stock gb fallow the instructions and root ur phone
then select the ics rom like lightening rom and flash thru odin
every thing will be fine
Reading the post, seems like OP did flash a stock file (although ICS, not GB).
2 dumb questions just to confirm. You have the i9100? not the i9100G? Also have you waited a certain amount of time after you flashed those roms? It can take up to a couple minutes for it to first boot.
If above are fine, (you have i9100, and you waited a long time and it was still stuck on i9100 screen)

Factory reset is not required after flashing a rom .
You load rom via Odin it finishes install and then reboots itself .
You load rom via CWM and it goes to reboot screen yes and phone reboots .
As said a stock gb rom flashed via Odin preferably after a format of system data and cache should be your first step .

i did that.

but should i go for flashing my phone with the .pit file?
Nooooooooooooo wait wait wait,don't ever touch pit files and repatition
i would try it but i hope it won't make your problems worse ...
[edit]
ok then not ...
Looks like you have siyah rc6. Make sure it's not from the 21st, iirc.
Don't factory reset just to be safe.. Restore your nandroid if possible and change to a later version.
Hope all goes well

yup i had siyah 3.1rc6 on my phone.
i tried to restore my nandroid backup but there is no effect on my problem.
how to know weather emmc is fine or currupted?
Try to mount it in CWM and connect it in linux computer and run fsck to check the eMMC. Windows chkdsk is no good.
And please try to remember, did you do this step: flash bad siyah rc6 then wipe/factory reset and get stuck?
if not, then the problem is different from those who flash bad rc6 (which is removed now and siyah is safe)
any thing is not working.
in every thread its written that if my phone goes in download mode and recovery mode then its soft bricked but then how can i unbrick my phone?
or is there any hardware problem?
i can mount and unmount every thing in recovery mode
i can format every thing but only user data cannot be formated,when ever i format/data or factory reset the phone hangs.
is there any other way of hard resetting i9100.?other than cwm recovery?
Have you tried flashing with the .PIT? I doubt it'll work, since other people also tried it, but it's worth a shot.

[Q] question about firmware and rom

Hello,
well, i'm beginner in all the android custom stuff but yesterday, I wanted to try jelly bean on my galaxy tab 10.1 wifi version.
So I've installed a rom custom with this tuto androidauthority.com/galaxy-tab-10-1-wifi-p7510-paranoid-android-2-custom-rom-114133/
But i'm not satisfied with it and i want to go back on the previous version I had : official ICS.
So i've a question : are the firmware (download on sammobile for exemple) simply updates or complete ROM that we can install on our devices?
In both cases, i would like to find a way to get back an official rom...:crying:
Can you help me please?
First rule of Android modding. Always make a backup in recovery. If you had you could just boot to recovery and restore the backup. To answer your question the firmware downloads from sammobile are indeed fully stock roms. They are designed to be flashed with Odin (.tar.md5 files) flash them in Odin the same way you flashed a recovery, point to the .tar file with PDA slot in Odin.

Tanks for reply,
Actually, I did a backup before, like the tuto said, but when i want to restore, i've an error during the restauration of the data so it stop and don't restore.
And like you said, I've flashed the file from sammobile with Odin and the installation seems to work but when I reboot in normal mode, I'm stuck at the Samsung logo screen.
So do you know a way to reinstall proprely an official ICS ROM, even if I have to format my tablet?
thanks for help

After downgrading, it's a good idea to wipe data/factory reset from whatever recovery you have (stock or CWM). Factory reset may resolve this.
Note that the first boot after an installation is slow.. the logo screen stays around for several minutes if I remember right.

Ended up fixing the problem, its seems as if the vesion of CWM I had was just stuck in a loop. I fixed it by reflashing it to a difference version of cwm . And you can flash cwm through CWM so this fixed my problem, afterwards I just installed cyaogen and everything works fine now .
Thanks for sharing!

It all depends on your android version. Kitkat requires 6.0.4.5 (I think and above). Jelly bean probably cwm 6.0.1.x or something like that. Flash a custom kernel (it's easy to do this).

samsung galaxy in boot loop(twrp)

i installed cm13 custom rom in my s3 then with twrp. it worked fine then i factory reset my phone then it starts with twrp screen and screen flashes and again twrp screen comes(screen with twrp written not options).i can just go to odin mode. what to do now
please help!!!!!
Never factory reset from a custom ROM. It is recommended to do it from recovery. Your reset has wiped too much including important parts of the OS. Flash another copy again.

Thanks for ur concern but i cannot open my recovery it is just teamwin written on screen any other method plse describe.
Maybe it is just loading? If after waiting for 5 mins. can you enter recovery? If not can you enter download mode? If yes then download a copy of the stock rom from here and flash it via ODIN.

This is a soft boot due to the fact you still have the ability to access recovery and such what i would suggest you do is get factory files and restore phone back to stock and start over this should fix your problem. If you look around XDA you will find the files you will need ODIN being the main tool you will use to flash your phone.

You have flashed a stock firmware with stock bootloader etc. using odin and still stuck in a soft brick ? remember to wipe the phone a rule of thumb i use is to wipe the phone 3 times before i flash and 3 times after i flash. during the first boot up it may take a little time to boot as it must rebuild the cache. I dont think it is a motherboard issue i think you may have just flashed a wrong file that needs to be wiped out before continuing on. i have had this problem in the past with a galaxy s2 when i was developing custom roms for it. it took me a couple of wipes and factory firmware reflashes but i eventually got the phone back in working order. look here for the factory files you will need to re flash your phone with odin ----> https://samsung-firmware.org/model/SM-G925I/ also make sure you are using the latest version of ODIN you will to put your phone in download mode instead of recovery
Hi, could you fix it ?? I am facing the same issue.
