Galaxy s2 operating system problem
 

A few weeks ago I got an update message from samsung for an upgrade of the OS to 4.0.3 from my previous Android 2.3.4 Gingerbread.
I absolutley hate this new system and after asking tesco to reinstall the older version Im told it cant be done.
Anyone know a way to revert my phone back to as it was before.

I'm still waiting for T Mobile to upgrade mine to Gingerbread! I'm assuming you've tried factory reset

Once the OS is installed it resets to that. I just got it back from tesco repair centre and specifically asked them to reinstall my old OS system but they told me it cant be done..
Got on the phone to samsung and they say "officially it cant be reversed" but maybe I should look online. Thats all he would say.
Previously you were able to delete single items from the google search history by pressing and holding the selected item and delete,but now the new google black stores the last 5 with no option to delete any single item from history. Its just annoying that you cant choose what to keep.

You need to root the phone and then install the Rom you want. Plenty of guides online.

Yep, get it rooted and try this rom:

:thumbsup:

Thanks for that info but after doing some reading it seems if I root it, it would void the warrenty and Its already been back twice in the last 6-7 weeks.
Before we proceed, it's important that we outline the risks involved here. Although in the case of the Galaxy S2 the rooting process is usually reversible, messing about with the inner-workings of your phone's software immediately invalidates your warranty. It may break your phone completely. CNET UK takes no responsibility for any harm that may befall your beloved handset as a consequence of you acting on the steps we've outlined below.
Looks like Im stuck with it.

Sorry to hijack.....

Stoff, T Mobile UK have released it but you need to connect your phone to a PC with Kies to have the upgrade as it isn't being released 'over the air' like the HTC phones I had before this S2 were.

I've tried that, but my computer says (via Kies) that my phone in not upgradeable...

Stop searching for illegal or horrible things to do with fruit!! :thumbsup: open a incognito window in the browser

Defeats the object I want to keep my favourites like oople in the list but this new os even lists your txts. Why do that when theres a call log for that. Its a mess. If you havent updated yet, trust me dont.

huj? You hate android ics?
why? :)

I too don't like the new Os system on my O2 G2 :-/

9 times out of 10 when I press the home key the voice search comes up which is getting on my wick!!!!

And going from previous phones I've owned....once you upgrade the Os that's it, your stuck with it :( wish I hadn't been in such a hurry to upgrade my G2 now :(

Strange, that's how I upgraded mine.


The short cut for voice talk is a quick double press of the home key. I do that too every now and then and despite searching around the phone settings I can't find a way of turning it off :thumbdown:

You can get rid of it. You have to download ESexplorer i think its called then delete the voice.

This is still my problem...

this is my current OS:

and this is what Kies says:

Phone was purchased unlocked from Tesco with a T-Mobile contract simcard. Anyone know how I can upgrade to 4.0.3?

Also... that's not my phonenumber.
Neither is this:

Have you flashed you phone?

Have a look here or here

I think you will have to flash the firmware/rom its explained in the forums there

Interesting (if a little over my head) reading there. Seems a few others are in the same boat with phones from tesco.

Phone has never been flashed/rooted or returned to a samsung service centre.
CSC shows XEU which (according to your links) the update has been released for.
Seems that my choices are to return it to a samsung service centre of flash it via odin...
My head's swimming with new terminology... where can I find the correct version of ICS for my phone (assuming I decide to go that route)?

Col give the tesco customer service team a ring. They should be able to help you out but once you download 4.0.3 your stuck with it and its awful imo. If you know someone who has it on their mobile ask them for a demo.

Tesco should help you, especially if they unlocked it
Why don't you like it? If its only to do with the browser thing then add another browser.

I really like mine and with Go Launcher you can customise a lot

You can try and find the official update.zip (its somewhere on xda developers) and put that on your sd card and just re-flash it using that. It doesn't need root or anything fancy as its a standard boot loader so it will just take it.

Am sure you can go backwards using the same method. Ask the question on XDA developers and see what they say.

Col,

Want me to bring my netbook and some roms to York tonight? Problem with the SGS2 is that it has an internal counter which keeps track of the number of times you've flashed roms, and when you send it back to the service centre, if its been flashed, no joy...

Best option would be to just bite the bullet and root the phone. Clear all the standard shit off it and install a standard shipping rom, not the Tesco one.

As far as someone disliking ICS. I know its each to their own, but i really dont understand how. Maybe if you're constantly "fat fingering" the vox button, you should try using a different browser or launcher? Just an idea...

Not there tonight buddy.
Got odin on the laptop and have downloaded LP5 4.0.3 so think I'm going to do it...now!
(wish me luck)

Good luck post what you do and how you get on Im sure there are others that will want to do the same thing

The problems are not just with the galaxy s2, Ihad a htc sensation which started on 2.3 gingerbread, then about 6 weeks ago it updated to android 4(ice cream sandwich) and since then endless battery life, GPS, gprs and forum posting from the mobile(deleting random letters ) so I have now gone down a spec to the Xperia arc s back to gingerbread 2.3.4 android. So far the right move.

Moral is don't update your phone to the new OS until its atleast a few months old and the bugs have been worked out.

With respect, you are clearly not a phone geek. I was running ICS on my old HD2 for almost 6 months. All the bugs have been worked out, now its all about tweaking.

I hate when people criticise that which they have less than a working knowledge of...

Without any respect back to you,
two o2 guru's and one HTC engineer all say the same that ICS is the problem and the bugs will take time to fix.

Riiiiiiiiiight!

So if these "O2 Gurus" and the "HTC Engineer" told you to jump off a bridge into the moon made of cream cheese, you'd be all over that too? Clearly everything that the companies trying to fob you off are saying is true...

There are ICS ROMs for the Sensation and the S2 that have been running fine for 6 months at least. I used to work with a lad who had ICS on his S2 in September last year, it was seeing that that made me look to put it on my HD2. ICS isnt the issue, the OS is sound, otherwise phones like the S3 and the HTC one X wouldnt be able to run it without issues, which they do.

Click me to see the Sensational light!

Click me to go to S2 world and see ICS ROMs that work

Maybe your Gurus and the engineer need to learn that Android is open source for a reason...

Correct me if im wrong but the 'open source' bit, yes andriod is based on a linux kernel, however google has propriotry rights on the apks that runs android. This means yes the source code is available for people to reverse code the os, but the bootloader, eg prior to the recovery update loader, the bit that makes the phone work with the os is google owned and as such the manfacturers have to pay google for these bits, this also enables them to put eula's that require us to sacrifice some of our privacy! as far as your critisim of O2 Gurus, thats not on, I used to be one, left to go back to the motor trade, and the amount of disussions with both devs, and manufacturers to get bugs and updates sorted you wouldnt belive. They work very hard, and as an example, galaxy 5500 text message repeat issue was solved by 3 of the o2 gurus, me being one of them, and the samsung devs.

Done and dusted. Was easy peasy.

Only downside was I did a hard reset first and forgot to back up my phonebook...

(if anybody wants to PM or text me their number I'd appreciate it!)

What rom/info och guide did you use?

http://www.hotfile.com/dl/153177481/...5_XEU.zip.html

Phone was originally CSC: I9100XEUKH1, but is now I9100XEULP5

As far as I am aware, the bootloaders arent google owned, otherwise MAGLDR/cLK wouldnt have been written and the whole ROM scene for the HD2 wouldnt have existed.

I have no doubt that the O2 gurus and the Devs work hard, they are attempting to bring order to the phones of the plebs. People who lack the ability to understand that installing that spyware and virus will screw their phone over, and I'm sure that a lot of issues for phones have been solved in colaboration with the devs and the gurus, but ENTIRE bootloaders, ROMs, frameworks and hardware drivers have been coded for over at XDA Developers, Tytung is a genius, as are a lot of the other guys, Cotulla especially.

All I'm trying to say is, look outside of the support number for your carrier and you might just find a solution to an issue that you're having. If someone told the disrespectful gentleman above that the OS was the issue, then clearly that person doesnt know that ROMs which work already exist and while what he is saying could technically be true, ie ICS is the issue, what he actually means is, our implementation of ICS is the issue and we're trying to sort out our buggy coding. The OS itself is sound, has been for a long time.
