Revert from ICS to GB - Galaxy S II Q&A, Help & Troubleshooting

Hey there, I installed ICS 4.0.3 on to my S2 yesterday, after using it for a day, the battery drains way too fast, the music player keeps crashing, and other various apps keep crashing. I would like to revert to GB 2.3.6.
I used to have KK2, and im on LP8. I dont play around with ROMs so these are all stock ROMs.
Someone please guide me on what to do. I did a search but that didnt help me much

I upgraded to ICS via kies and did not wipe after upgrading....will wiping make the phone work any better, I am wanting to downgrade due to the battery life being VERY bad with ICS

m8 check pm***

Wipe will make day and night difference but you will lose your apps and data. And you should not restore your backups from GB to Ics
Dial *2767*3855# to wipe

Hey fellas, i'm looking to send my phone to Samsung for servicing, but obviously i cant let them see that i'm running ICS because it isnt out in Singapore yet.
so i've download DXLP7 in hope that i could flash my country's firmware before returning my phone.
Download both the kernel and the 7zip file that is 310mb in size.
opened the massive file to only find one tar file, so if i flash that via odin, my phone will completely return to stock?
as in a condition that the service centre wont suspect?
what about the kernel that i downloaded, do i have to flash that as well?
Much appreciate some help.
Regards,
Shawn.

Look at the battery status wich app is draining your battery.
Yesterday i didnt use my phone for 2 hours, before my battery was around 50% but after the 2 hour my battery was only 18%. I looked at my battery report/status and it said:
Xda 29
Screen 27
And some things like
Bla bla 7
Bla bla 4
...
Mostly my screen haves around 60% so, now xda is the same value but the screen didnt use more or less energy so.........
Thanks to the xda app my battery drained 2x so hard.
I gues (how do you spell that?) you also use the xda app and it alsobis your problem.

Hello All,
I am a noob.
So I am looking into going back to GB 2.3.5
I have flashed stock ICS Netherlands XWLP7 and I have downloaded the firmware of my country.
Which is: GT-I9100_EGY_I9100JPKJ2_I9100OJPKJ1_I9100XXKI4.tar.md5
And kernal: Kernel_I9100JPKJ2.tar.md5
I have a question, it has been explained to me that I need to flash these files using odin+flashing a PIT file and using re-partition.
I could not find a PIT file? where do I get it from to go along with my firmware?
And, do I need to flash a Modem?
Is it possible for the kind soul thats going to answer my questions to put it in 1,2, 3 steps so I can understand what do to first?
I.E
1- Flash kernal
2- Flash firmware
or what?
Thanks a lot!

@ Sn3aks:
What is the reason you are downgrading to GB?
What is the condtion of your phone now?
Who advised you to use pit file?
---------- Post added at 10:02 AM ---------- Previous post was at 09:59 AM ----------
the firmware package you have mentioned already contains a kernel, no need of flashing kernel seperately..that is uploaded in the thread for future use when you needed to flash after rooting.

---

Thanks for your reply.
I am downgrading cause GB is more stable than ICS. Music player lags with some songs
Random crashes
I can not modify the in-call headset/handset volume from the servicemode. If you click Audio it doesnt come up with anything. And the in-call voice through earphones is really low
And other stuff that annoyed me and I couldnt remember.
The noticeable improvement in ICS is battery life and performance is fast
What is the condtion of your phone now?
My phone is ok, working fine, making calls, going over the internet normaly, IMEI is valid. Not rooted. Binary count = NO
Faryaab advised me to use a PIT file. I checked the guide in your signature and I read that anyone who asks about PIT file is a moron. Is this my case?

---

I dont think PIT file is required in your case,
You can try without using PIT first.
GT-I9100_EGY_I9100JPKJ2_I9100OJPKJ1_I9100XXKI4.tar.md 5
select above file from PDA of ODIN.
Do a factory reset before flashing...
