Question about downgrade - Galaxy S II Q&A, Help & Troubleshooting

Hi, recently i've updated my sgs2 from android 2.3.3 to 2.3.5
this update is terrible, everything is screwed, apps fail to run, wifi connection is not possible (it never connects), it lags terribly and also all the interface was changed (really hate that blue scrolling thing)
some people say that 2.3.5 improves battery life, but i didnt notice any change, seriously
so i was thinking of going back to 2.3.3, which was awesome and i didnt have any problem with that, now i know im stupid that i used the kies update and i will never do that again
what do i need to do it?
iam from czech republic, so i was looking for some czech version of 2.3.3 on google and also on this forum but found nothing
i bought my phone from vodafone (not branded) does it affect my choice of possible firmware downloads?
thanks for any help!

Use Google search or Checkfus to find it .
Look for the original firmware codes matching the firmware on the phone .
Or even take the time to read the stock roms post and instructions .

HELP: Want to Upgrade SGSII with 2.3.6 / 7 (DBT)

Hi Frnds,
I am newbie in SGS2 Family i bought Samsung Galaxy S 2 and update my first firmware update with official update 2.3.4.
So my Latest firmware is : PDA:KI4 / PHONE:KI1 / CSC:KH1(DBT)
Now i want to update it with 2.3.6 or 2.3.7 as official firmware is taking to give update on my country and right now i m in india.
I don't know about which Rom m i have and what kernel i m using.
So kindly please please let any friend help me which kernel or rom should i upgrade with so ill be having latest firmware update on my SGS2 mobile.
Please pls help me.
If you updated via KIES, you have the stock Samsung ROM. You can see the kernel in settings -> about.
If you want something that isn't available from KIES, you have to flash a custom ROM, pick one from this list. I think the only one that is 2.3.7 is CM7 (and maybe MIUI), those are AOSP ROMs, a tad different from Samsung ROMs, so I wouldn't advise them for a newbie.
Other than this, please read around the forums, most of the questions were already answered, and no one likes lazy and stupid people asking lazy and stupid questions.

Actually there are so many thread i just have confused what to download pls show me one way rest ill findout promise ....
Sorry if i broken any of forum rules.
thanks
At the moment for India there is no official 2.3.6/7 available and if you look at the firmware your phone has you will see that it has a german csc(DBT).The only way to get to what you want is to flash something like KK5 and then a custon ROM with a built-in multi-csc package that contains the csc for your region or one that would at least do the same job.XDA have INU as indias csc although a neighbouring countries csc will quite often do the same job.Seeing as your phone is on a german firmware(DBT) Kies will search for the latest german update unless you want to flash it.

Look in the development section. There you will find the things you want to know. Flashing roms involves risks, so you should start learning what everything means. It will save you a lot of problems.

Why do you want to update when you have just got a new phone ? You will hardly notice much, if anything, by updating. Use your phone as it is for a couple of weeks, find out what you like and what you don't like. In the mean time read about all these threads here regarding rooting, flashing methods, various ROM/themes etc.
Is it really that hard to find?

Actually bro i have lost my warranty card while traveling and it has local warranty.. so any way i didn't get any facility on such.
i heard in 2.3.6 battery life is much better and i have 2.3.4 which is relatively good but not enough if i play, browse battery not only stay a day..
So i thought to upgrade it...! Thanks

If you dont want to flash a custom ROM you could go to the link below and flash from the "Frankinstein" section at the bottom the KK5 firmware then factory reset your phone,boot to download again and flash the India ODD KF3 CSC from the csc section given at the bottom and then when its done you need to do another factory reset again.This will give you KK5 with your local csc.Thats what I did on KH3 here in Spain to get my csc(FOP).Take into mind that these are not without risks if you dont follow the rules of flashing.A nearby countries csc will also do the job just as well so flashing KK5 and then a custom ROM with a multi csc package is always a go but its your choice.KK5 with the csc flash will be more close to stock looking and custom ROMs bring more mods and themes.

Phone wont update through Kies

Hey guys samsung stated ages ago that all UK unlocked phones can receive the ICS 4.0.3 update through Kies, I seem to be the only one who still cannot update through kies message still says your device cannot update through kies, I have rung samsung support and gave them all my detials numbers firmware numbers eventually they told me that it was my computers fault and that my phone should update normally through kies even though i have told them i have tried on 3 different computers, so im now asking you guys as a last resort to help, before you guys ask i do have the latest version of kies my phone is NOT rooted has stock firmware never been flashed with a third party here is my phones details,
PDA: I9100XWKH1
CSC: I9100XEUKH1

Chris i think you missunderstood my problem, i do not want to install a custom rom or root my phone i was asking here why my phone cant update through kies when my Code XEU is listed as Official ICS Update,
Ignore his root your phone post Updates do not require root as it would void warranty .
Kies updates your firmware when the phone provider has updated it .
You can use CHECKFUS to check on the server and download directly .
Alternative is to flash stock Samsung roms from XDA posted in General and also in stock rom thread .

Try your service provider...
Hi,
I´m in Spain and using Orange. The last time I was able to upgrade my stock ROM, the change came from Orange because they customize it (basically to lock you into using their system). If you choose to stay with a stock ROM, then your service provider may have to supply it and they are a little bit slower than Samsung because they have to add their changes. They usually add quite a bit of "Bloatware" to justify their modifications.
So I rooted my phone and am now using custom ROMs - Resurrection Remix 1.1 and am really glad to be rid of the Orange system. I also unlocked my phone so that I could use SIMs from other countries. Hopefully this will prove helpful....
Hi, quijote1, my phone is unlocked and unbranded so i am not tied with any network in the uk or have any bloatware as far as i know it is a standard rom,
Hey ZacQ8, As i previously stated in my OP my CSC is XEU, witch has been rolled out by samsung through kies that's why i have made this post in the first place.
could my problem be my firmware version? and is flashing with odin my only way now of getting ICS for my phone?
hey guys any idea';s?

You are making an assumption that ICS is available for your actual phone . That may be wrong .
You can use CHECKFUS to actually see if the ICS for your phone is on the Kies server .
Alternatives take the phone to the vendor/Samsung service for an update .
Join XDA Developers forum and flash stock Samsung roms on the day they are released .
You have no other routes except to ask Samsung /your phones vendor why you have no update .

Hi there i got my fone 5 days ago and as soon as i got it i checked to see if there was any software updates thru check for updates and there was ics any so i don't understand how urs ent come yet i dent do it thru kies

may i know malaysian s2g can update to ics??
still confused myself as XEU is released so ICS should be avalible through my phone and i dont wanna flash samsung roms myself just incase i brick/invalid my warrenty, i guess the only way is to take it to a samsung repair shop but dosent that mean i have to pay for the update when others get it for free?, just frustrating, is there anyone here who can sugest the correct ICS rom for the Code XEU?
update: ive found my product code and there is a ICS firmware on checkfus do i download it is it the right one? and if so why dosent kies see my phone as a possible update?
Sabsack said:

UP to you your choice .
it is it the right one?
Who knows you put the codes in correct then presume so if not its easy to tell once flashed .
and if so why dosent kies see my phone as a possible update?
You need a clairvoyant or try asking Samsung .
Personally in your shoes i would stick with what you have and not bother updating .
Because the next post you make is probably how do i restore to GB .

[Q] Unbrand 3 (Three) Italy Galaxy 2

Hey guys.
I just received a TRE (Three) Italy branded GSG 2 with the following PDA, PHONE and CSC info here:
PDA : I9100 XWKI8
PHONE : I9100 NEKI2
CSC : I9100 HUIKI1
If I install the XWKI8 Stock Kernel from here, using ODIN, will that work ? I want the same version of software, but with NO BRANDING.
Afterwards I want to upgrade my phone to ICS, but I just want to get rid of the 3 (Three) icons and bootscreen first.. Afterwards If I want to go back to the 3 (Three) version if I install the one with the info above will it work ?
Thanks a lot guys.
Stock answer is read the debranding post .

No as you dont have a clue and need to read the Faqs and Guides first .
Kernels are not firmware you require full firmware . Read the thread instructions .

Q
Okay. Got it. read them. Ty JJe.
So from what I've read I understand that I can install whatever firmware that is available here, under the OFFICIAL FIRMWARE section, the original and current firmware that I've got being available here, under the 3 Network, under Italy.
Can I install _ANY_ firmware ? Or any other one that has the same PDA version (XWKI8) ?
Afterwards.. If I want to go back to the original FW the phone had, is flashing the firmware version above, under the 3 network, Italy everything I have to do ? If for example I've got a problem with the phone or software and want to use its warranty. Ty.
Thanks all.

Flashing the New XXBLG6 ICS 4.0.4 Firmware / JUST RELEASED

Hey guys. I have the I9300 and my build number is IMM76D.I9300UBALF3 , and I just read that the UK is getting OTA update for XXBLG6 with some nice improvements. This website says that I can simply download their file and use ODIN to install it.
http://www.android.gs/update-samsung-galaxy-s3-i9300-to-official-xxblg6-ics-4-0-4-firmware/
My questions: will this infringe the warranty by any means?
Why does KIES not show that there is an update?
Is it possible that my phone will not be compatible with the update as it probably is not a UK model? ( dunno the difference )
Is there a chance that flashing the update will brick my s3, since I am not actually rooting or anything.
P.S. - I do not have root and I do not plan on getting it yet.
Thanks guys. I appreciate any help!
If u have the correct model number, u can try and it won't brick ur phone normally.
But it is at your own risk.

You would need to ask that web site bit stupid asking another forum for advice on another forums products .

You do not have an update yet .

Yes if its not I9300 International model .
Kies will not offer a UK update to a phone that is not a UK product code .
Is there a chance that flashing the update will brick my s3, since I am not actually rooting or anything.
Yes always possible .
P.S. - I do not have root and I do not plan on getting it yet.
As you do not know what phone you have you would have two choices .
One wait for whatever your phone is and Kies to update it .
Two you could join XDA Developers forum download the stock UK firmware and flash it on the day of release .

The risk is very small but it is a small risk that gets much bigger if you do not follow the instructions .

I do know what my phone is lol. It's the i9300 , just not sure if my firmware is a UK firmware or a different one. The improvements are on the stability, noise crackling sound, camera features, screen brightness easily accessible.
So since I know that I do have the international version I9300, can I update through ODIN without risk? or? Furthermore, will any build work for the I9300 no matter the location based firmware?

If your phone is not carrier bound you can flash any region as long as it is for your model.
Yes, there is always a risk using Odin. But then again Kies can jack your phone up too.
I put my faith into Odin. YMMV.

[Q] official Belgian stock firmware 4.1.2 for galaxy S3 GT-I9300

When I bought my Phone I almost immediately received an update to android 4.1.2. recently I unrooted my Phone and wanted to flash the stock firmware again, but it seems that I can't find an official Belgian stock firmware above 4.0.4
And if I install this one and check for updates it says no updates available.
Does anyone know if this update was only temporarely available, or where I can get the official one I had?
Thanks for you help.

I already checked these websites before I posted my question.
I know that I'm maybe a newby, but if you say the answer is there than please show it to me, because on al these suggested sites the latest firmware for Belgium is 4.0.4.
You failed to mention the fact that you searched those sites .
I did not say the answer is any where .
I said it was answered in your identical thread .
The links i posted are in reply to
or where I can get the official one I had?
Links are the places where you can get stock firmware but as you gave no indication of firmware required and as i refuse to search on behalf of others i suggest you google the exact firmware build you require .
