my solution
to solve it, first I think "the problem is the kernel", well I download the siyah kernel and flash it. later I put on the device but doesn´t boot. I find on internet the stock kernel and flash it. It doesn´t boot...... . finaly I download the stock firmaware (2.3.4) and the new JB 4.1.2 and I flash the first but doesn´t work and later the 4.1.2. this time the phone start normally and it, does a "boot-loop" (only one) and now it works perfectly.
PD: sorry for my english

It is a... Bootloop.
To fix the problem:
1- Flash Siyah Kernel or any other Custom Kernel like SpeedMod or PhilZ
2- Reboot into recovery mode
3- Do a Wipe Cache
4- In advanced, Do a Wipe Dalvik Cache
5- Reboot

Yup as he said it's a bootloop , but you don't need to flash again (since he already installed a custom rom) a new kernel the bootloop can be fixed by wiping data then wiping cache and wiping dalvik cache after installing your rom.
Recommending Siyah is just to make sure you are on a stable kernel, but most custom kernels associated with custom roms are good enough.

[Q] How to make a ROM full wipe on flashing

As title basically, I remember reading something about wipe roms having a extra 'data' file inside the archive which triggers it but cant find anything more on it. I wanna have an XEU LP7 ROM that wipes on flashing.
Sent from my GT-P7510
If your flashing the ROM via a CWM flashable .zip, the updater script will have the commands to format the various/required partitions.
You will need to add the extra lines and re-zip prior to flashing. If you're using Windows, you need to use NotePad++ to amend the script (not NotePad).

Wirh a manual full-wipe you have besser control.
1. factory reset
2. format /system
3. format /data
4. format /cache
5. wipe dalvik
6. wipe battery stats
7. format internal sd-card (not ever neccesary)
flash
format SD ex-SDcard >>>> everything in ex-sdcard gone ), you must copy rom again to intener store and flash ^^
You can also nuke it.

Then flash a matching Siyah kernel via Odin to see if it boots.
If it doesn't boot, try entering CWM recovery after flashing Siyah. Then do a full wipe.

[Solved] Suddenly Boot Loop on Chameleon 3.0 ROM

Hi,
Below is my phone detail:
I9100
ROM: Chameleon 3.0 beta
Kernel: Siyah v 6.0 beta 4
Today, i used MXPlayer app to watch a movie file (HD); exited to menu; and open MXPlayer again; and choose to resume from last position.
However, suddenly the phone was restarted and going into a boot loop.
I have tried to:
- wipe dalvik cache and wipe partition; unsuccessful
- take out battery, take out external SD card, put battery back and restart: unsuccessful
- flash Siyah v 6.0 beta 5: unsuccessful.
- tried flashing other kernels: philz, dorimanx: unsuccessful. In fact, when i checked the system menu, the kernel which i installed was not there.
- tried flashing back Siyah v 6.0 beta 4: able to be read as the Kernel in the system menu. However, when I press power button, there is no Restart to Recovery mode appears.
I really don't have any idea what is going on.
So, any help is appreciated.
Thank you very much.
Please make this clear - can u boot into your phone, or are u stuck in a bootloop?

Stuck in a boot loop.
I can boot only for a few seconds (less than 10 seconds); just enough time for me to check the system.
Additional note: I can still access CWM recovery (pressing power+menu+volume up).

Try re-flashing ur current ROM.
If that doesn't work, try a full wipe.

Take a look at Hawkerpaul's scripts from here http://forum.xda-developers.com/showthread.php?t=2100558
Wipe your phone, reflash your custom rom of choice again, should do the trick

Tried to flash the same ROM without wiping data... Doesn't solve the issue.
So finally did a full wipe and flash Chameleon 3.0.1 with stock jeboo kernel.
Solved the problem.

[Q] Stuck on bootlogo

Hi,
I am running stock 4.0.3 ICS XWLP7 on my I9100, rooted with CF-Root 5.4 and wanted to update to 4.1.2 by using Chameleon ROM 3.0.2...
So I went to recovery, did factory reset, wipe cache, wipe dalvik cache and installed the zip file, but after rebooting I am stuck at the bootlogo (with the yellow triangle). After ~10 min. I pulled the battery and rebooted. I was able to get into the new recovery so I tried to flash it again but got the same error.
I am now back at 4.0.3 (nandroid restore).
So.. is there something obvious I did wrong?
TIA for your help.
Did you format system first? If is not working try another kernel

[Q] Root - Flash Problems

hello there guys ...
im confused and in trouble, my problem:
i got a sgs2, had a jb firmware from sammobiles.com, i tried to root my phone,
flash a kernel and look i softbricked my phone and that like 3 times ...
and now, i downloaded again a jb firmware from sammobiles and my phone works now.
i dont know how to root, flash kernel and rom, can someone help me out here ?
i read the threads about root and flash instructions, but still, im dumb -.-
Make it simple, I assume you already know what model you've got so just flash a custom kernel meant fir your device. Get the tar version and flash it via Odin.

The instructions are quite simple:
1. Wipe data / factory reset (mandatory if you coming from STOCK OR 4.2.X version or another ROM)
2.- Install the Main ROM
3- install gapps
4.- When you're back on recovery go to Advanced
5.- Wipe Dalvik Cache
6.- Fix Permissions
7.- Wipe Cache Partition
8.- Reboot
All these options are easy to find on CWM. Which part confuses you?

[Q] Phone won't boot after upgrading to 4.3.0

I have finally decided to upgrade my SGS2 and install Android 4.3.0 (currently using an old version of CM 10.1 based on Android 4.1.2).
After wiping my device (wipe data/factory reset, wipe cache, format /system) and flashing a new ROM, everything worked fine, but when I rebooted my phone it didn't boot anymore (I could still get to recovery/download mode though). This has happened with several 4.3.0 ROMs I've tried...
I've been looking for a solution for a few days now but found nothing, do you have any idea what may be causing this and how can i fix it?
Try flashing without GAPPS at first.
Try format system, flash ROM, Boot, If succeeded reboot and flash gapps. (ensure its the current version - and I suggest the CORE edition.)
Also try using a ROM wipe script before flashing the ROM.

I used GS2ROMNuke (http://forum.xda-developers.com/showthread.php?t=2100558) and it seemed to do the trick! My phone is up and running (even rebooting correctly) now with Android 4.3.0.
I will post an update in case it breaks up again (which hopefully it won't).
Thank you!
Good for you! Let know what happens.
