[Q] how to get out of bootloop on s 2 - Galaxy S II Q&A, Help & Troubleshooting

first time i install cm10.1 nightly on s2 i9100, there was no prob...then flashed pacman rom ..was a little glitchy and slow.
So moved on to paranoid android..this is where the prob started... it keeps on bootlooping :?
Right now flashed stock 4.1.2 via odin and rooted with siyah kernel s2 v6 0.5b ..works fine
but if i flash any custom ROM it bootloops ,even with the prior cm10.1 that i had..
checked xda , did a lot of work but still stuck at square one..{wiping this , wiping that}
only thing i can find fault with is in recovery when wiping data says
Format/sdcard/.android_secure ..fail
skip Format
Format completed
when trying to intsall from sdcard it says
E:/ cannot mount..
tried different cwm recovery .. all with the same findings..
so please help me.. its boring to be stuck with stock ROM..
i am a doctor ..i tried but couldnt follow running SDK and commands ..so please keep it simple
or if possible publish a video.. bcause iam not the only one with this predicament...during my research i found a lot android users with the same problems..
Thanks

Thank you..ammar but as i have already said my phone works but with the stock rom...i end up bootlooping only when iinstall custom ROM
n the solution given in that thread 1. is to flash a stock rom.. 2. flashing villain rom but the download links are not working..
i think it has do with fail to format .androidsecure thing but what do i know?
again thanx..

also backup all ur internal memory data to a pc and then format your Internal memory from within the rom

You could try using a couple of wipe scripts by a guy called hawkerpaul....I think they're called 'romwipe' and 'kernelwipe'.......
Use the XDA search function....should be easy enough to find.
It may be that there are some 'leftovers' following the usual wipes (cache, dalvik and data) that are causing conflicts with your fresh installs.....
The above mentioned scripts perform a more in depth wipe....might help.....

i have tried that GS2ROM wipe and nuke scripts already, with no luck ... yes that runs bigger wipe but it still fail to format sdcard .andoidsecure
i think it has do with renaming of the sdcard{silly doubt when recovery states sdcard , it doesnt refer to extsd right?} from sdcard to sdcard0 while installing CM10.1,,
if i could safely erase that {.andoidsecure}, probably things will back to normal .. anyone know how to
oh iam not able to use install from sdcard option in recovery(formerly before flashing any ROM i was able to..i hav to install from "internal memory"
Again iam grabbin at random bcause i want to go bac to custom ROMs. .if any of sounds untechi ..let me remind u i am just , what do they call it.. a noob and i do apologise...

i can find folder .androidsecure in extsd card and that erasing that doesnt solve the problem.. there must be another copy
iam not able to find .androidsecure in sdcard {internal}..with neither ES explorer nor Root explorer..
i dont know if this helps but i tried to intall that int2ext mod once but it didnt take ..installation aborted in recovery..i cant really remember if this was before or after i started havin the bootloop problem...Most likely after ...when i was running stock rom
There those are all the cards ...someone please solve the puzzle...
