I guess your friend's SGS2 is root so, the instructions will always be the same.
Copy the Custom ICS Rom in the internal/external sdcard.
Reboot the phone into recovery mode (volume up+home button+power button).
If your in the recovery mode, go to "install zip from sdcard".
"choose zip from sdcard" or "choose zip from internal card". This depends where he/she puts the custom ICS rom.
Select the file.
Choose "Yes" and wait for it to finish.
Now, you have to "wipe data/factory reset".
and then "wipe cache partition".
and then "reboot system now".
Hope this helps.

You asked the same question 3 weeks ago and got an answer.

I don't know about GB to ICS because back when my SGS2 was SHW-M250K (Korean Galaxy S2) I took a risk by flashing Litening ROM using Odin and hoping that it would be a success and I'm glad to say that it went perfectly. But now, I flash JB ROM and ICS Custom ROMs via Recovery Mode and not by Odin, and Yes, I do full wipe I flash roms in my phone.

It doesn't matter what from and where to.
This way always should work:
0] BACKUP APPS (U would not loose ur Data from sd card)
1) Choose Firmware/Rom
2) Put it on internal sd card (I it's flashable .zip, otherwise u have to flash via Odin and check 'Re-Partition'!)
3) Go into recovery mode (see above)
4) DO A FULL WIPE!! (U won't loose ur backup on sd card)
-- wipe data/ factory reset
-- wipe cahe partition
-- advanced > wipe dalvik cache
-- mount and storage > format data/system/cache
5) Then flash Rom via recovery
-- install .zip from sd card > choose .zip from sd card
-- Select the downloaded Custom Rom and flash it
6) Reboot and u r done!

Before or After the rom's zip installation (flashing) do you wipe data/chace factory reset + wipe cache + advanced and wipe dalvik cache?
mostly because of corrupted download

[Q] HELP: Omega 9.1 boots into CWM

I'd really appreciate some help guys, I've searched everywhere but can't seem to find answers.
I had Cyanogen Mod 9 rooted on my phone, however, I decided to install Omega instead, I installed it but I can't get on it! Everytime I install zip and reboot, it goes back to CWM Recovery!
The procedure was:
-deleted all files in internal SD
-Reboot into CWM Recovery
-Wipe data,cache,dalvik
-install zip from sd card
and now im stuck
Please help, and apologies if any noob mistakes were made

You'll lose all your data but do a factory reset and wipe your system in addition to what you've already done and re flash the rom. FYI always have a nandroid backup around before flashing. It's time consuming but saves you a lot of grief in the long run

Factory reset(wipe) is an option in cwm(3rd from above) wipe and reflash the rom and let it boot,this can take 10min
1st check md5 .. it will show u wether its bad download or nt ... and then do this
go into cwm and to wipe data\factory reset wipe cache wipe dalvik and insll rom ..
omega 10 is up so better try omega 10 as its new rom :

Factory reset is on the main Cwm screen. You can wipe system through the 'mounts and storage' option

How would put it into my internal SD if I can't transfer the file because I can only boot into Recovery or Download mode? Do I just Odin it straight in via the PDA option?
If you connect your phone with the PC while in recovery you should be able to use adb commands
Put the rom file into the adb folder than try
Code:
adb devices
now you should see any cryptic combination of letters and numbers in the next row
(if you see a empty row... that wouldn't be nice^^)
then do:
Code:
adb push yourromfile.zip /sdcard/yourromfile.zip
than try flashing again the new file
dont forget to do a full wipe, cache wipe, dalvik wipe, the common procedure^^
PS:
If you don't know about adb, it is installed with the android sdk, but you can download it seperately
place the ADB folder somewhere on you system hd, maybe directly to C:\
the open cmd and type
cd C:\ADB\
now you're able to use the above commands
You can put it on an external sd and flash it from there...

Thank you, all of you... I will try this tomorrow and tell you guys how it goes!
Thank you so much EVERYONE, It all worked out, seems like the original file was corrupted, now running omega 10 smoothly!!!!!!!

I think i found the stock rom at the general dicussion area
Downloading the stock rom , will flash later and see the results
huh,u formated /system
the only way is Flash stock .ftf firmware via flashtool.
if u wanna clean the /system (wanna flash different base ROM), format that but DONT reboot ur phone.
For next time, wipe only DATA, CACHE, N DALVIK CACHE.

Yes format system, but don't reboot. Just format system and after that choose zip from sd card and install it. That's it. Don't reboot after formatting system!

Why into booting part? You just format system and press back key and after that "choose zip from sd card" -> install zip from sd card...

6. Go advanced > wipe dalvik cache
7. DON'T REBOOT
8. "install zip from sd card" > "choose zip" > choose the base rom > install it.
9. DON'T REBOOT
10. "install zip from sd card" > "choose zip" > choose the patch for your device> install it.
11. DON'T REBOOT

Oh your bootloader is unlocked?
So first flash ics 4.0.4 rom ftf via flashtool and before your reboot just plug off device and plug in while holding volume up and flash rage kernel for 4.0.4. Now reboot.
Just in case, enable unknown sources and usb debuggin and connection mode msc.
Afterwards do that:
Download the base rom zip and the patch zip for your device.
1. Put the downloaded files on your sd card
2. Boot in cwm
3. click data/factory reset
4. wipe cache partition
5. go to mounts/storage > format system
6. Go advanced > wipe dalvik cache

Basic recovery comes with those 4 options only so nothing is lost...only CWM has more options
Now...don't ever do a factory reset and wiping cache before installing new rom...when you install a new rom it itself formats them
Again...CUT your rom from sd card to computer and again copy it to your sd card....SAFELY REMOVE and again choose apply update from sd card
If this too didn't work...download a new rom and follow what I've said

if u root your phone using odin for the first time you should have cwm installed on your device. if yes then u can install developed roms / rooted roms on your phone. you can find diff roms on galaxys2roms.com
for installin a new rom on a rooted phone check the rom website(whichever rom u wish to install) there will be steps.
normally those will be like this (for rootrd fones)
1.download the rom ( zip file)
2.place it on your external sd
3.open cwm and reboot to recovery mode or Power off your phone and go to CWM Recovery
4.Wipe Data and Wipe Cache Partition and Wipe Dalvik Cache
5. Select install zip from SD card and select Rom
6. Fix Permission (if coming from higher/older Android version)
7. Reboot your phone
