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
see my signature link for ODIN flash guide and stock roms

I have odin and the stock roms.....which were given to me, i would just like to know the procedure, to go from ICS to GB as I think i need to wipe my phone and so on.
The file i currently have is GT-I9100_XSA_I9100XWKK2_I9100XSAKK1_I9100XXKI4.tar.md5
yup do a full factory reset and flash gb via odin **imp** jus for ur info the modem of ics remain afta flashin gb too,well i seen it all the time and i used to flash gb modem separately..
just make a factory reset from the phone menu,
and flash it form ODIN...
there are newer GB versions available than your choosen one...
I just hope you tried the newer ics stocks and wiped after flash and didn't restore anything. Ics working just fine on my brothers s2 for a month and I'm running stock just fine since yesterday

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.

Do a factory reset before flashing...
I just bought a used galaxy s2 I love the phone already. I had the samsung infuse before, and I loved the cm7 nightly builds on that phone, but had to upgrade You all know how that is haha.... I used http://forum.xda-developers.com/showthread.php?t=1505172 to root and then had to unlock seeing as I am on rogers.... First thing I have to say is that every time I boot up I see the triangle with the ! in it so I might have done the wrong one? It said before i had the i9000m btw. And I installed CF-Root-SGS2_XX_OXA_KG2-v4.1-CWM4 as the kernel
Another thing I might as is that when I tried to open odin 1.85, it would say Odin.ini with a bunch of sqaures, i press ok and it closes.... So i just used 1.83.
Last thing is who do I go into cwm recovery, and I want to go on a cyanogen mod 7 or 9.... Should I try cm9? And how would I do that?
THANKS!
Hope everyone here is more helpful than on the infuse sometimes
the yellow triangle is always there when you boot it cause you rooted it.. but gladly, you can remove it with a usb jig (http://www.youtube.com/watch?v=udzMQ_dsci4) or without usb jig (http://www.youtube.com/watch?v=YOXNf_kH-iA)
I highly suggest skipping CM9 and giving Resurrection Remix a try. Also learn to live with the yellow triangle and forget the CF kernels. I use Siyah kernel and there are other alternatives just as good.
I've tried almost every rom and kernal for S2 and I truly believe RR and Siyah is the best performing combo of them all.
Sent from my GT-I9100 using Tapatalk 2
Thanks I will trythat now, but how do I do that? I sent you a message
If you don't have a usb jig to reset the flash counter and remove the triangle on boot up try chainfire's TriangleAway app either found on the play store(paid) or in his thread here on xda(free). Make sure you are running an ICS rom.

Sorry I meant how do I do the siyah and rr thing but thanks
I received your message. All the info you will need is right here on XDA already. When you rooted your phone you probably installed CWM recovery (press home, volume up and power buttons to boot into it). Assuming you have that you can just follow the steps in the RR thread to install. It already comes with Siyah Kernel so you can simply flash the latest version to keep it updated. I used odin to flash a modem firmware for Canadian networks but that's optional since the stock base band in rr worked fine.
Sent from my GT-I9100 using Tapatalk 2
So that means all I do is flash rr from cwm and clear that bs stuff and I'm good to go?
Sent from my GT-I9100M using xda premium
Its simple as that Just follow the extended steps in the faq of the rr thread and remember to make backups in cwm in case you make mistakes and need to try again.

if u need to do a factory reset/full wipe in the process of intalling the new rom
all apps and data will be deleted
so its convenient to make backup important things like your apps, sms, or call log
not compusory though
backup apps using Titanium backup,there are free and paid version

Stick with GB. CM9 AOSP AOKP and Samsung ICS roms will give you a headache, poor performance and poor battery life. My two cents.

There is no stock UCKK6 (2.3.6) but you can download and flash a Stock plus root version of UCKK6. See Entropy512's thread which is a sticky in the development forum.
...Or you can flash fully stock UCKH7 (2.3.4). See the link in my signature for the return to the store guide.

I will add this if you flashed UCLE5 via kies or any other method to get your ICS besides AJ's thread you have an unsafe kernel and possible eMMC SUPERBRICK BUG make sure you DON'T wipe data/factory reset before you flash this package do it after you flashed a safe GB kernel... If it were me knowing KK6 2.3.6 has battery drain issues I would flash KH7 2.3.4..... Just use creeys thread to get the files here is the link... GL
http://forum.xda-developers.com/showpost.php?p=18859438&postcount=199 For KH7 stock or rooted.

i flashed I777UCKH7-REV02-home-low-CL503881.tar
that i had got from sammobile i didn't see the other post till now and i also upgraded to ics from kies i can get into download mode but when i try recovery i held power and volume rockers and it's suppose to flicker once it does not do this it just stays there
You can upgrade to the stock 2.3.6 by downloading the stock 2.3.4 firmware from the download repository here in our forums, then after you are booted into the operating system, go to settings, scroll all the way to the bottom to software update, and it will download and install 2.3.6. I wouldn't suggest it , just because I don't like it or think it runs well, but try it out. Good luck, happy flashing.

Why would they not take it back?? You never flashed any custom ROMS from here right? All you did was flash the AT&T ICS update via kies and it gave you problems right? Knowing all that = true I will do all I can to help you (the only problem is I don't know anything) If you don't respond back in about an hour it's 6:30am now on the West coast I have to roll out for awhile.

- Do a factory reset, it is recommended after software upgrade or downgrade
- switch to custom kernel if the problem persists
Good luck

yes
Yes, on ICS the battery drain was very fast while using wifi or screen on sometimes it drained 1% in 1 sec so in 10 mins 10%.
I am currently on stock gingerbread rom (rooted)
I few minutes back installed one live wall paper and noticed that screen use to come up after few seconds. After uninstall the same screen has not come up.
But still i can see awake 3m (188 secs) 16.1%.
thanks

Speedmod kernel, make sure you are flashing the gingerbread version.
Flashing an ICS kernel will result into bootloops

i would like to recommend u to use stock kernel
and make sure to do a full wipe also format / system before flashing
a stock rom (untouched) and check ur battery if drain fast... then u should replace it ...

this is due to the fact that your battery reading is still inaccurate, the fuel gauge is trying to settle down/calibrate your battery.
Ps: if you can reupgrade back to ICS, I'm sure I'll be able to narrow down and fix your battery drain issue

since you presently have root access, you can just flash a custom stock based Rom, with less bugs all the way.
It's faster and safer than using kies or whatever they call it

i can hear the samsung logo load up but cant see it.
I can boot into recovery and download mode. what do I do??.. reflash latest 4.1.1 firmware via Odin?
If this works how best to go about rooting as i dont know if i want to try the s3 toolkit again if it clearly didnt work (although all messages pointed to that it did)
Thanks in advance
