Hi,
if you download the right build from CyanogenMod 10 there is no problem, watch out for "I9100" in the buildname.
But if you want to stay on stock it would maybe help if you do an factory reset in the recovery

http://www.sammobile.com/ download the rom of your country and flash it... these are stock roms (no rooted) if you want stability... just back up and wipe everything... factory reset..wipe cache after flash the rom... and format of your internal sd...

[Q] Problem: Every ICS -> Crash in HS - Plz help

Hey guys,
here is what is going on with my German Vodafone I9100
After using Sensation Rom for a few months, I finally decided to make the transition to Android 4.
The first rom I tried, was the Simplistic ICS by LegendK95
Installing from CWM worked like a charm, booting worked like a charm, but whatever I tried to do, the phone freezed in homescreen randomly after 5-30 seconds. Only a restart bring it back to work, only to make it freeze again after the mentionend time span.
Whatever I did (waiting in home screen, pulling down the statusbar, scrolling in app drawer) the phone always freezes.
After dozen of restarts, I installed the rom again, the problem stayed.
Then I decided to go to stock 4.0.3 (LP6). Installation via Odin worked like a charm. Booting worked like a charm, but the homescreen-freeze-problem got even worse.
I also tried to reinstall the stock LP6, but the phone now even froze in CWM mode, while data reset AND WHILE INSTALLING THE FW.
Now I got a soft brick in my hands.
So, I installed stock 2.3.3. via Odin. The phone now worked flawless again. No freezes, no no nothing. Just a working phone.
My final try was to install the latest CM9 build.
Guess what happend?
The legendary homescreen freeze. That nobody else appear to have. YAY
So, somehow my phone seems to be allergic to Android 4.
Can somebody please help me?
Regards
PS: Yes, I followed the instructions every firmware provided.
Honestly you want an honest answer. Stay clear of ICS leaks and yes that means even cm9. Reason being. Because of what they are. Leaks and nothing official. Not saying that they are not good but if you look at the original android development can you see any actual ICS roms? No. Why you asking? Because no kernel sources have been released and nothing is far from stable yet. Even cm9 builds codeworkx has on the thread title experimental. So my advice. Flash a Gingerbread custom rom slap on it the ICS by vertumus and your good to go till the official stuff get released.
Maybe before flashing ICS you should fully wipe your device to get rid of all previous ROM data from Gingerbread as they,I imagine,wont be very compatable.
Boot to recovery and go to "mounts and storage" and format System/Data/cache and then factory reset.Then flash the Rom via recovery(install zip).If its an Odin flash then reboot and flash via Odin.
Hi suarez,
thanx for your opinion. I read a lot of threads before updating and came to the conclusion that the current releases, even CM9 seem to be pretty stable.
Also I found no one having issues like that.
Hi cooza,
I did that.

No problem my friend. But I still stand by what I said though. For me to make the jump is a no go yet. Yes they might be stable but so far I still read problems regarding video forever, this is not working that does not work and that most issues will be solved once kernel source is available. Hence why still the experimental on cm9.thread.

Yes, but if you're not that big into watching/recording videos on your SGS2, it's pretty freaking stable.
Installing the latest experimental build of CM9 is probably the best thing I've done to my SGS2 as of late. It's just so... Nice.
I cannot get rid of that problem.
I really need help on this.
Some new information:
I also tried to flash the leaked stock LP2. Same result.
This FW crashed on first start, when the Samsung Apps are installed.
Still some little success:
When flashing from stock BUGKJ2 straight to LegendK95's Simplistic ICS rom, I was able to get it to run, until I have to restart the phone.
But this was the only rom capable of doing so. Every other fw failed.
So, I now can have ICS on my phone but only until I restart the phone.
After reboot, the phone crashes again after some seconds.
Additionally the CWM Recovery doesnt work as long as I have a ICS rom on it.
It also occasionally crashes. Preferrably when I try to flash a new rom, leaving me a shiny brick
Here are the steps to get Simplistic ICS run until reboot:
1. Put the file on internal memory.
2. Go to recovery: wipe data/factoy reset, wipe cache, wipe dalvik, wipe battery, format system, format data, format cache
3. Flash from internal sd
4. Reboot

Maybe the problem is the stock firmware you first flash.I searched for it but cant find it,is it carrier branded?..BUG sounds like it to me.Maybe you should fully wipe your phone (format System/Cache/Data) and first flash something like XWKL1 and then the ICS ROM.If the ICS ROM you are going to flash has a multi CSC package in it then it wont matter what F/W you flash first.
hello cooza,
i had to go back to stock 2.3.3 because my phone was a brick after flashing any ics rom.
i tried to flash simplistic ics and cm9 via cwm, i dont know if those contain multi_csc.
however, the leaked stock roms, lp2 and lp6 both contain multi_csc that i flashed via odin.
here are all the steps i tried:
fail 1: flashing from sensation rom 3 (2.3.6) to simplistic ics
fail 2: flashing from 2.3.3 to cm9/simplistic ics
fail 3: flashing from bricked ics to stock lp6
fail 4: flashing from 2.3.3. to 2.3.5. (latest official release via kies) to cm9/simplistic ics/stock lp6
fail 5: flashing from 2.3.3 to leaked stock lp6 inluding the pit-file provided
nevertheless, flashing from 2.3.5 to simplistic ics worked until restarting the phone. however, cwm was not working correctly then. so, surely i could have tried to let the phone on for forever, but as soon as i would want to flash a new firmware, i would have got a brick left, because cwm would crash during installation of the new one.
there must be some help out there
thanx for trying cooza. much appreciated.
You might have a damaged bootloader.Although its not needed you could try a JTag.A JTag is used to bring a hard bricked phone back to life.You dont have a hard bricked phone but what it also does is repairs any damage that the bootloader may have.Costs about 25 to 30 euros.As a last resort you could give it a go if your phone is going to give you constant reboot problems and not let you flash firmwares.It should also repair any repartition faults because it completely wipes the bootloader before repairing it.The phone will come back like the first day you got it.check the link below out and use it to find one close to you if you choose to do one.I had an i9000 done last September here in Spain and it came back perfect from a hard brick soo I know it works.I used the link below.

Seems like the very last option to me
Would a broken bootloader allow me to run 2.3.X flawless?
Question does Samsung stock firmware work .
As it seems all your problems are from using a buggy unreleased test rom not from using Samsung released firmware .
I would if it was my problem .
Clean Slate for those that balls up the firmware .Or need to return to service or decide if its hardware/firmware problem .
Backup data first if phone is working .
Boot CWM recovery
Mounts and Storage
Format cache data system sd card wiping everything on the phone .
Remove battery
Boot to download mode
Open Odin
Install correct Samsung stock firmware for your phone model .
Test phone works .

hi JJ,
thanks for your post.
as i said, the phone is working fine on stock android 2.3.X as well as custom firmwares using 2.3.X.
However, all 4.0.X firmwares I tested, showed the same behaviour: crashing my phone in homescreen (or anywhere else after booting) AND in cwm after 10 to 30 seconds.
only simplistic ics custom rom worked fine until first reboot. then it crashed as well. everytime.
I tested 2 stock firmwares of samsung and 2 custom roms.
I also tested flashing 4.0.3 (CM9) on a friends SGS2 using the same procedure I used on my phone. It worked on first try and he`s now a happy android 4 user.
right now i`m running on CM7 but i wanna uprage to android 4.
edit:
up to this date there is no official released 4.0.3 rom for the sgs2 but how can it be that I have the only phone showing such a behaviour while everyone else has a 99% stable fw for the same phone using the same rom?
Mate,at least it works,thats the important thing.I can understand that its frustrating when the only Firmware/customROM you want doesnt work in your phone and only your phone but we are talking about BETA version ROMs.If there is something for some reason blocking the ICS ROM then it is possible that the JTag will clear it up as it wipes and repears the bootloader as I mentioned so any corrupt data will dissappear.Ive had a bricked phone done and it still works perfectly today but never a phone in your situation.Its possible but never having done so I cant guarantee it.If you want give it a go.You got nothing to loose except 20 or 30 bucks for your efforts.
I have exactly the same issue with a "german" Galaxy S2. I tried to install the {CWM}İCS REMİX ROM v8.4 ULTİMATE ONLİNE XXLP6 4.0.3 resurrection NO-WİPE
Version.
Followed ofcourse the installation instructions letter for letter. It doesn't go over the logo screen. ( And yes I am aware it takes several minutes for such an installation to finish)
I read in that thread of at least another 3-4 people with the same issue.
Going back to any 2.3.x works as usual.
If you take the time and read the various ICS posts one inescapable fact will arise .
ICS suffers from many varied problems with no two users reporting identical problems .
That is compounded by two factors one the boot loader and two as a beta test rom for some strange reason those with very little knowledge rush to install it .
But hey save money on the Samsung testing department just leak your Alphas and Betas .
For me i will play with a test rom for an hour or two but thats it i require a stable rom for daily use . It will need vast improvement for me to consider the final release of ICS for daily use .

GSMArena say that Samsung are launching ICS for the S2 in march
http://www.gsmarena.com/samsung_galaxy_s_ii_and_galaxy_note_to_get_ics_in_march-news-3752.php
with this I imagine that stable ICS custom ROMs are just around the corner so if you can wait a few months more you will be able to flash a stable safe ROM without any problems.Until then the BETA versions that are out at the moment are going to cause these types of things.
I had these same isues with KP8 on my s2. I fixed them by flashing LP6 directly over kp8 without wiping anything. I think it may have something to do with the phone drivers you have installed on your pc. They may be damaged and be producing some kind of error on the flashing proccess. I recomend that you hard reset to 2.3.x and reinstall kies on your pc. That should reinstall phone drivers too. And make sure kies is NoT running while using odin. Kies doesent like odin

I have patience As long as I fallback to a functional rom everyting is cool. As for the alpha-beta testing, I have nothing against it and I didn't complain about it. Till March I hope the S3 is out so I can pass my S2 to my better half ...

[Q] S2 Ics rom Isuues

Missing calls in new ics Stock roms i have installed DXLP7 & XXLPQ both i am getting same result .Phone is idle even though people can hear the caller tone , i have reverted back to ginger bread .Any solution for the same please update
Try a factory reset and check again .
Sent from my GT-I9100 using xda premium
I have tried that also same issue .. when mobile is idle i believe its going to sleep mode ,caller can hear my phone ringing but i am not receiving calls going back GB .
when you have strange issues dont blame the OS why dont you try dialing wipe code and check.
going from GB to ICS dont restore anything from GB.
use odin and flash official stock not the leaked one.
first time i upgraded from gb to ics , second time i have done factory and cache reset from recovery ,still the same i know something to do with my phone will do a code reset planning to clean the storage before next installation , will a give a try and i am using odin and official f/w only.
you can still try code wipe if you want no need to reflash. but if you want to go from scratch, best way is to format all partitions including system. than go odin way.

AOSP Roms are faster in my opinion. Try them out. Few stock roms are amazing, but after a month or two they get slow, idk why too.

1. Flash actual firmware with Odin. Afterwards boot into recovery and exec factory reset. More effectiv would be:
2. Root your phone, if not done yet. Flash TWRP recovery with Odin. Flash NCS-ROM: based on newest JB-firmware, debloated, fast, battery-friendly.

Trouble installing Resurrection Remix 5.5.9

Hello,
Yesterday I have tried installing a new ROM to my old Galaxy S3 I9300, to make it more useful, since my main phone is dead. Stock 4.3 just works like ****. Battery drains in literary one hour from 100% to 0%, when connected to my brand new JBL speaker music played trough YouTube freezes, but video is still rolling , apps like Snapchat cause phone to glitch and even freeze when battery is below 50% and so on. I believe one thing I can try is to give this phone a somewhat fresh ROM. I have quite some experience with installing aftermarket ROMs from other phones, but in 5 hours of straight frustration, I couldn't figure out how to do this on the Galaxy S3
This is what I did:
1. Successfully rooted the phone trough my PC using Kingo Root, downloaded Resurrection remix 5.5.9 & Gapps 5.1 and put both zips to SD card
2. Installed latest version of CWM custom recovery
3. Nandroid backup
4. Wiped data and formated cache
5. Wiped dalvik cache
6. Installed Resurrection and gapps from SD card
7. reboot the phone
And then I expected to boot up into the new android, but when the Samsung Galaxy S3 I9300 startup logo appears, it just keeps flashing for 5 seconds, in 1 second intervals, nothing happens. It is not even an bootloop it just doesent even start booting up? What the hell am I doing wrong?
Then I wiped data again and restored backup, I was able to boot up back to annoying android 4.3 and at least keep the phone useful.
Another issue I have with this phone, which can hopefully be fixed with new ROM, my phone detects SIM card, I type the PIN, register on my operator's network, but then a notification pops up saying: selected network (my network name) is not available.
I can't make calls nor use the mobile internet..
I will really appreciate all the help
Rule #1, if your phone is too slow buy a new one. You can't polish a turd.

Yes you can.
Try flashing another ROM like lineageos or latest cyanogenmod 11 (really fast and stable ROM)
I suggest starting over by flashing the latest stock ROM with Odin, flashing TWRP with Odin, and install all ROMs/zips using TWRP.
Root is not required to install TWRP when flashing TWRP with Odin.
