[Q] S2 ICS downgrade or rom?? - Galaxy S II Q&A, Help & Troubleshooting

i had upgraded my S2 to official ICS just few days before but i find that there are many problems like my errors in apps.
Can i downgrade it to solve these problem or by other sorts of method??
Can i directly flash a new rom in official ICS???
sorry for my silly question, but i can't find any solution.

Did you reinstall the apps trough the market? Or dit you restore a backup trough a backup program??

Ten million same questions.

Question about firmware

I have a question. If i update my s3 via OTA, does it mean i'm updating to a stock rom? Will it affect my rooting or whatsoever? And can i downgrade if i want to?

Yes and yes. But you can easyly reroot with CF-Root. Or you can flash the firmware with mobile odin pro then your root is untouched. Yes you can flash other firmware to downgrade.
Firmwares can be downloaded at sammobile.com or checkfus
If you update via OTA firmware stocks of your s3 , you will receive an update of your firmware stock samsung, updates are no wipe , you can make a downgrade with ODIN ....
I have another question. I'm enroute to flashing the omega rom on my phone. If the official jellybean comes out, what do i do? Install via KIES? My phone will still be in the rooted stage right?

As soon as official jellybean drops there will be a custom ROM out within hours, and the firmware will be available at samfirmware.com as soon as it is released.
You'll have loads of options.
The custom ones will be pre-rooted, the stock one from samfirmware can be rooted with cf-root. (The leaked one can so I presume official one will too)

That isnt the problem heh. I always backup my data before flashing.
By the way, my version of triangle away, I cannot see the flash status when i load up the app. I have to go into download mode to view my flash counter. Any ideas?

Unrooting, everything back to normal

Hi. I have rooted my S3, to see how it works with PS3 joystick (i am not too impressed)
I have rooted successfully via odin flash guide, but now i get strange problem.
Every now and then, when i want to turn on dispay, it works and show me that clock and then when i swipe to unluck, the phone doesnt respond.
When i power again, display dimms, and nothing happen. I cant unlock my phone, I need to hold power button to reboot, and than it is normal till i lock the screen and want to turn it on again.
My question is, how can i solve it, and if i can't, how can i get everything back to stock and normal?
Try turn off ripple effect in setting, see how it goes.

First of all, try disabling lockscreen entirely.
Then try performing a full wipe. If nothing changes, flash stock firmware via Odin. If this haven't helped, root your phone, reset bootloader flashing counter via TriangleAway, then flash full stock firmware and make a warranty claim.

As i thought, now, without changing anything, the problem goes away. But i think it will came back
I forgot one big thing!
!!!! When i first flashed PDA, i flashed it with something CF, not insecure kernel (MY FAULT). Then i got this problem but i can say that i couldnt use my phone. Only just after reboot. Then i flashed insecure kernel, al now problem is still here but it is not so often, but i must fix this.
So maybe the problem is because i flashed wrong file, so "bad" files are still here?
Is there an easy fix for this?

My problem is back, so i tried this 2 first things. To desable lockscreen entirely, and to turn off ripple effect. No, it is still not working..
Start from scratch again. Backup your data, flash original firmware with odin, root it again, triangle away if you want.

Ok now, here is my next question.
I flash original firmware form here? http://forum.xda-developers.com/showthread.php?t=1671969 Is that right or not?
Than i know now hot to root, and i think this triangle away is easy too.
And one more question, which firmware is the newest and best? This XXALF2; Firmware Info PDA: XXALF2 Phone: XXLF2 Date: 05/06/2012
I remeber that i had OTA this month so 6th month is pretty old IMO :S
You can go to sammobile.com to find the latest firmware for your country. Then follow the instructions as in the link you posted above.

Why not just flash custom rom for now and wait for Jellybean original firmware release.

Are custom roms for s3 better than original? I had HTC Hero for almost 3 years and i had custom roms for it but it was only because i wanted it to be faster and smoother
For me, yes custom roms are better than original stock rom.

No idea why you don't want flash full firmware, there nothing wrong at all
Yet, just use mobile odin pro, open file, choose the stock rom, then clear everything except recovery

How to install a ROM? or I mean how did you install the 4.2.2 then do the same thing with 4.1.2
Sent from my GT-I9300 using xda premium
Be aware tho that you will have to fix the layout of your internal SD afterwards. As 4.2.2 changes it because of the multiple user feature.

If the Important DATA is stored in ur phones Internal Sdcard (the 11.5 gb partition) then u can safely flash any stock firmware from ODIN
for stock firmwares u can check.
www.samfirmware.com or www.sammobile.com
and u can easily search for a video guide on youtube on how to flash a stock firmware on i9100 using ODIN.
......or you could check the stickyed threads on this forum right here on XDA for Odin flashing instructions.... No need to look elsewhere on the web when everything you need is RIGHT HERE......
This might be my S2, or it might be my W...but it's definitely CM
well its a CWM prob
1. search threads for how to flash stock rom back via odin
2. re root and install cwm
3. Install the correct rom

well modded roms are like for example
some devs take the stock rom push their kernals with some minor or major tweaks
it might be in UI or apps or can be of anything
in simple works taking a stock rom or any other rom and overlaying it with some tweaks
