Hi @javiwz, and welcome. Unfortunately you have posted in the wrong thread for your device, but the Mods will soon relocate it to the correct forum for the i9100.
In the meantime you should look here for help in returning your device to stock, then rooting > flashing new firmware. If your device won't get past the boot animation (assuming my interpretation of your issue is correct), then you would be perhaps best served in starting over from the beginning.

Hi Javi and welcome to XDA.....
So....your phone is stuck in bootloop.....
Don't panic fella....plenty of things to try.
First thing....you can try one of two types of data wipe.
1) cache wipe
2) data wipe (factory reset)
Both of these wipes are done in recovery.
How to get to recovery? If you don't already know, here's how.......
Turn the phone completely off.
Wait a few seconds then press and hold the Power, Home and Volume up keys together. When you see the samsung logo release ONLY the power button.
The phone will continue the boot into recovery.
Once in recovery, release the home and volume keys.
Then....
Use the volume keys to scroll down to 'wipe cache' and select that option with a press on the power button....and if you are asked to, confirm it.
Then try and boot your phone as normal.
If that doesn't work, go back in to recovery using the same method as before, but this time select 'wipe data' (factory reset).
I suggest the cache wipe as a first resort because it will leave all your apps installed, whereas the data wipe / factory reset will remove everything from apps to settings to passwords which will mean setting your device up again as if it was new.

[Q] galaxy ace bootloops

Hi guys.
i installed Launcher Pro Plus 0.8.5 for Galaxy S by mistake on my Galaxy Ace.
First the phone was laggy about 5 seconds, then rebooted itself and i'm a stuck at "samsung" screen. Phone just vibrates, but won't boot. I removed battery a tried to start it again, same issue....passes boot animation, but then bootloops.
could anyone help me please?
the phone is 2 days old from orange store.
This is pretty critical, i need to get it working till sunday.
But i don't want to lose warranty. I can enter download mode atm.
Could anyone please help me?
how do i remove that app from my phone, when cannot boot?
i tried to search samfirmware, that i would ODIN stock rom, but i don't know my PDA key - i cannot select the best PDA key.
I am from Slovakia, phone bought in slovakian store, if anyone could give me correct PDA.
thank you guys
Wait.. Isn't LauncherPro an universal app? I mean how could you say its SGS specific when anybody with different phones can download it from the same place?
That aside, since the download mode are OK, you can just try to re-flash your current ROM.
The warranty will be void only if you root it or put different ROM into your phone.
If this helped you, would you mind pressing that lil thanks button below?
Why Dont you try entering in recovery mode and do a wipe data/factory reset to enter recovery press home key + pwr on key, you mevo trough options with volume keys and select wit home button jus select wipe data/factory reset
i just wiped data..i was trying volume up + home key + power button, like on SGS.
well with that launcher pro....i guess it will be other version for ace...sure you can download it from market, but i think it's some different build or something.
anyways, wiping data/factory reset solved this issue for me..
thank you guys!
i personaly would root the phone in first 30 minutes i get it, install some cool custom rom and enjoy the power of the phone, like i did on SGS, but it is my GFs phone..she almost killed me when this happened
wipe is more than enough to reset. and i can't help myself stop thinking people on xda abuse all this flashing thing - it's everybody's solution for every problem - RE-flash. NO NEED to reflash if you haven't rooted/flashed your phone before - flashing just voids your warranty in this case. and it ain't only topic affected...
sorry for being picky, but i'm in exactly same shoes here - i've been doing whatever with my SGS, but my missus's ACE is no go (until good rom comes ) - so i can imagine being given advise to flash, because i got bootloop... bit silly...
some sort of noobs guide/tutorial topic from OP/someone respected e.g. devs regarding whole flashing idea would be beneficial for many,many people. it's my opinion only. thanks

[q] startup screen hang please help

hi i have a samsung galaxy s2 GT-i9100. i am from singapore (if region matters). i updated to the official DXLP9 4.0.3 whatchamacallit version (via the automatic update service) less than a week ago, but i didnt like it for various reasons, of which a very unsatisfactory battery life was the one i couldnt stand the most.
so i went to flash the DXKL3 2.3.6 stock rom (with odin 1.85) as i thought it would be enough to revert my phone back to the old version.
BUT i was grossly wrong. my phone now hangs at the start-up screen, and ONLY at the start-up screen. and by startup screen, i mean a black screen with white text saying "galaxy s2 gti9100" on it.
I HAVE NO IDEA WHATS WRONG somebody please help me. :/
i suppose its bricked? so is there any way i can get it working again? preferably without wiping my data please.
i apologise if im breaking rules or anything by doing this but im really really desperate for my phone to work again so please help/make an exception or somehing thank you very much and in advance to any kind soul who responds.
Did u wipe ur phone before flashing it n after flashing??? try this may b this will work first wipe ur cell than flash GB through Odin
ics to GB without data wipe, don't think so

OK you can try to go into recovery if you are root by pressing volume up+home+power key , if you aren't and install other rom via recovery, if you aren't root you can go into download mood by pressing volume down+home+power key and also flash another rom using Odin
I think it may be soft brick because your phone responded to the power key and show you start up screen
Best regards

[Q] SGS2 after firmware update phone got "locked"

Hi everyone,
Please excuse my English and my knowledge about all this subject is so limited.
Today I connected my phone to Kies and was offered firmware update automatically. So i went for it (believe that it will be only for good) and the phone is now in some sort of freeze mode. It only starts up to "S Samsung galaxy S II" screen and that's it. Completely non responsive. If i try to turn it off it restart itself to that point again.
Unfortunately i can not provide any details of my phone as i cant get access to it right now. i remember that it was on gingerbread and firmware update was offering icecreamsandwich. its Galaxy S2 i9100
i don't know if its related but I'll mention it. This morning i followed instruction (i found on this forum) how to root my phone. Although i am not sure, everything went smooth and according to explanation. If was working fine until this firmware upgrade. Once again i don't know if this contributed to fail or not. Kernel i needed for my model was GT-I9100_BVKE2.
I would appreciate any help how to go back to square one (if possible) and make it work.
Thank You
OK so if you updated it to 4.0.3 and Not 4.0.4, then enter stock recovery (power, volume down, home button) and do a factory reset. Then reboot.
Edit: I mean volume up button

Thank you for your reply - how do i perform factory reset? From phone? I got to "android Downloading" screen (power, volume down, home button) and what then? Do I need to use Kies ...?
Thx
Recovery is Vol up+home+power. You move through options with volume keys and select with power or home button.

I got it from youtube.
NOPE - it wont allow me to go factory reset menu. Only goes back to "S samsung galaxy sII screen".
Does this mean what i think it means?
If youve lost stock recovery then all you can do is go to download mode and flash a 4.0.3 .tar file you download for your region from sammobile.
Then you can root the phone.
Thank you everyone for your inputs.
I went to local store and sort it out for £10. I wish i had more time to play with it but to be honest with you i lost my nerves at some point.
Thanks to all for your help!! :good:

Well you just wasted £10. You could have fixed it yourself in minutes if you had bothered to read in first place. There is plenty of guides and help here and its just a forum or search button click away.

Rooted i9300 no screen problem

Hi all,
Have a really bad problem, just rooted a galaxy s 3 for a friend, i've rooted many, he was on 4.1.1 i used the toolkit as i've used it before.
The root process worked well and now the phone boots up, makes a sound and then doesn't show anything on the screen.
Now nothing comes on the screen at all although it does make a boot sound (the samsung logo noise) the only thing i get on the screen is the galaxy s III logo and a small red exclamation mark up the top left.
Really would like to get this back on.
My friend bought it from singapore, although it is a i9300.
I can get to recovery and i can also get to download mode.
Any ideas?
If it is a I9300 then factory reset from recovery or flash a stock rom .

Actually sorted this now, I used the older toolkit and it caused this issue. Wiping it wouldn't have helped.
Used the new toolkit and all is well again.

I'm suffering the exact same problem (likely for the same reason - used older version, although possibly just because I messed up on my own).
@dladz, or anyone else who might be able to help, could you please give me a pointer on where to go after downloading the newer toolkit. I have a vague idea but I imagine it would be better to ask at this stage before I really mess it up myself.
If anyone could help you'd be a life saver
---------------------
Edit: After prodding around and "fixing" it I thought I'd leave this information for other noobs so they don't ask the same question/harass dladz like myself.
Simply boot up holding the vol down and home button, connect via USB and open Odin.
From there make sure that only Auto Reboot and F. Reset Time are checked.
Click PDA and select C:\Samsung Galaxy S3 ToolKit\root\GT-I9300\boot-stock-ella-GTI9300.tar (From the toolkit - http://forum.xda-developers.com/showthread.php?t=1703488)
Hit start and wait for the square on the top left to turn green and say pass. The device should reboot and be work again. As I'm a retard you may decide not to follow these instructions for your own safety and the safety of your device, however it worked for me.
Apologies for being a pain in the arse, I'll go back to lurking quietly and I'll try not to break anything else.

[Q] How to Fix Samsung Galaxy S2 (Korean) getting into recovery mode on restart

Hey,
I have a Samsung S2 (Korean Version) which was working fine. Since, it is being used by my younger brother for games etc. He informed me one day that the phone is not getting started. I checked the phone, switched it on and as it displayed Samsung SII logo and jumped straight away to recovery mode.
Resultantly, i installed AOKP rom using CWM recovery. The phone started and was working fine until restarted. On restart the phone again goes to recovery mode instead of loading the Rom.
Can anyone help me in fixing this ??
I refuse to help lazy people who insist on using such silly/generic topic titles like "Help Please" instead of using common sense and putting something relevant.
If you expect people to enter/read your topic and help instead of skipping or entering to leave remarks like mine I would recommend changing title to something useful for forum browsers.

did your rom could get into the operator interface after get in the CWM mode? if not ,try to install a new rom and back up your data,then wipe data cache and reinstall again. maybe your brother deleted some system files which make the system run regularly. therefore the phone jump to CWM when restart.

Dont worry, its not a big problem.
Press & hold POWER BUTTON + MENU BUTTON + VOLUME UP BUTTON for 5-10 seconds, then you will see something written in Korean language. Just ignore that and press VOLUME UP BUTTON. Then u will enter the boot menu. Use VOLUME KEYS to move up and down. and to SELECT something click on POWER BUTTON.
DO A BACKUP FIRST AND THE RESET UR PHONE.
