[Galaxy S II Q&A, Help & Troubleshooting] Talbred:
Hi guys,

I have a doubt regarding the upgrading/downgrading of firmwares on our wonderful device.

If I come from a custom ROM 2.3.3 for example, and wish to upgrade to custom 2.3.4 ROM, do I need to first flash the stock 2.3.4 firmware, and then apply the CF-root, or having CWM recovery from the first ROM is enough?

Thank you!

[Galaxy S II Q&A, Help & Troubleshooting] lanciadelta:
If you root your phone your warranty is VOID...When rooted you must update manually.Rooting and updating are two completely different things.UPDATING is means your basically your installing the latest software to your device..ROOTING - I advise you to research this as you can render your phone useless.This is a short description...ROOTING means you are gaining full control of your phone.You become your own administrator e .g - You can now control your cpu or you could block all adds from your phone.You can remove apps that you previously couldn't.You can flash custom roms etc etc...You need to do research...SERIOUSLY

GT-I9100 in Australia

Hi everybody.

New user here from the iPhone world. Been doing a lot of reading but still not overly clear on what to do, hopefully someone can help me out.

I have an unlocked and unbranded SGS II, the GT-I9100 model, not the T model that is supplied through my carrier, Telstra.

The phone I have was shipped with the latest Arabic firmware, so I'd like to install a different firmware to suit my location better. I'm looking at the Gingerbread 2.3.5 firmware, should i just flash this in it's evtirity, or will I need any other files for the modem, CSC (for settings)?

Just a little confused on what to flash, I've read up on ODIN and am happy with the process there. Any clarity to help me get this phone up and running as well as it can would be greatly appreciated. Not looking to root just now, if ever. I don't understand what it's all about yet (similar to jailbreaking I know that much), but like jailbreaking, I want to read up and learn a bit before attempting anything.

Cheers.

Been through that thread, there is the Telstra firmware but I didn't want the bloatware they add. Went for the 2.3.5 version (non wipe under the frankenstein heading), phone is set up and seems to working very well. Data speeds are as quick as the Telstra issued GT-I9100T I have. I'm looking to sell that one as I have no use for 2, but wanted to be sure I'd be left with a good working phone. Seems as though I'll be fine, although kies doesn't like what I've done, I'm looking into that now.

Hi, i just bought the galaxy s2 a week ago, my first Android/Samsung device (before i used Symbian devices). Now, i live in Pakistan & understand that Samsung updates are very rear in this region, currently i'm stuck on GB 2.3.3 and i want to use 2.3.5 (official) on my device because i think that the current build has a few noticeable bugs. Can i do so without voiding warranty??

Sorry i don't quite understand one of the threads in the development section about the official firmwares , could anyone guide me plz on which firmware i should flash =P...Here is some of my device info, hope it's enough:--

Android Version:-- 2.3.3

Kernel Verion:-- 2.6.35.7-I9100XWKG1-CLlabeltest_I9100XWKG1

Base band version :-- I9100XXKG1

Build Version :--GINGERBREAD.XWKG1

Also,

1- Will I be able to downgrade if i wanted to?

2- Will i lose all my apps/games by installing a new firmware?

Thanks =)

I recently got a Galaxy S2 after 3 years of having owned iPhones and jailbreaking them.

A quick FAQ (sorry, did a search and couldnt find concrete answers) :

- I understand the need for a USB jig to unbrick a S2, but do you need to use a USB jig every time you want to add a custom ROM / or root ?

- my S2 already came preloaded with a custom ROM (bought it used). How would I restore to original firmware, if I wanted to ?

Sorry, still in the learning stages of Android hacking, so apologies if these questions sounds a bit n00b.
[Galaxy S II Q&A, Help & Troubleshooting] novanove1:
Hi,

You can Install the new Stock ROM 2.3.4 or 2.3.5 from Samsung.

Installing the original one and not rooting it will not void the Warranty

you can download the desired ROM from the link ( http://www.samfirmware.com/fwandroid.htm )

I suggest you Install the Arabic Version so that you will be able to have urdu as well (If you need it)

You will need to do this through ODIN.

its simple.

I can guide you as well

You can also Download the guide from ( http://hotfile.com/dl/116098667/0a2f565/I9100_Flashguide.pdf.html )

( http://www.samfirmware.com/WEBPROTECT-guideandroid.htm )

You need to register in Samfirmware.

All you would need to do is Reboot in Download mode by pressing and holding down the Down VOL + Home + Power button. then Connect to ODIN and follow the guide.

let me know if you need any help.

Good Luck!

I believe so NO, you only need that to remove the Yellow Triangle (In Rooted ROMs)

---------- Post added at 05:13 PM ---------- Previous post was at 05:09 PM ----------

and Yes you can Downgrade it any time you want

You will lose the Applications and everything, except for the things on your SD, like the Pics and all or what so ever on it.

You can have a backup of your apps but you will need to Root your phone for that. (which will void the warranty)

you can always come back to the Stock ROM later on as well if you start using a Custom ROM.

theres no harm

from 2.3.3 to 2.3.5

How I can update my android 2.3.3 to 2.3.5 if I have my kernel I9100XXKH1, I can't find the update for this kernel. Sorry if I ask something that is obvious, but I'm new and from what I've read before I see that you need some other kernel. I have got the CF-Root for KH1 after I've updated my firmware with kies. The stock kernel was I9100BVKH1. Can someone help me to figure what are the steps and tell me if I'm wrong about the kernels. Thanks!
[Galaxy S II Q&A, Help & Troubleshooting] novanove1:
Its easy, not a biggy..

I had KH1 as well and Rooted KH1 itself and then later on I flashed 2.3.5

Just Copy the ROM on your SD card, Reboot in RecoverMode from CWM or by holding the VOL UP + Center Button + Power Button until it reboots in to Clockwork Mode.

Go to Install From Zip Card, Locate the Fil and Install the ZIP (READ THE NOTE BELOW 1ST)

NOTE: 1st Have a BackUp !!! > Then Wipe Data > Wipe Cache > Wipe Dalvik Cache

and the Install the ROM..

One thing that is different the colors of the phone are slightly lighter, the contrast before was much better. Before rooting i don't know wich version of Kernel I had. After rooting I have 2.6.35.7-I9100XWKDD-CL161513. Could be because is a different version? And still I cannot sim unlock it. I have tried SIM Unlock and no code given and the other way with BusyBox and Galaxy S unlock and still nothing.

its ok, you can ask anytime, I love sharing knowledge, I my self learned everything from XDA only.

Yes you can use the same procedure.

But the Custom ROMS are much better than the Stock ROMS. if you need to enjoy the SGS2 on its fullest, you need to have a custom ROM.

It's probably registered lost or stolen, so barred. If you got it from a reputable source, take it back... Otherwise I'm afraid you might have bought an expensive paperweight. You might be able to check with a UK provider if you have a SIM of theirs.

Btw, selling it on in the knowledge that it's stolen is also a criminal offence. Sorry.

Hi guys,

Some noobs question when flashing from build x to y. Is there a way to backup the current ROM to be exactly the same, I mean like. How the desktop is, icons etc. I heard about Titanium backup, not sure if it does that.

Thanks
[Galaxy S II Q&A, Help & Troubleshooting] CerebroJD:
It depends on which two roms you're going between, I suppose. You're going to be challenged since titanium backups of ADW (and a few other launchers) dont restore widgets properly.

When moving between roms, its probably better to rebuild your 'desktop' from scratch.

Edit...

If you're just updating nightly builds, or something along those lines, you shouldnt even need to format the /data/ partition, since typically build updates dont require a change in user-built data.

Edit edit.

If you want to back up EVERYTHING, exactly as-is, then just go to the Backup and Restore section inside of the ClockworkMod Recovery

Arrggg Questions About Different models of SGS2's

Ok so I recently got the SGS2 and love it. I am a very low tech geek and want to learn about this phone and have spent the last week on forums reading this and that and yet still kinda lost and confused...

There are Various of Images of the SGS2 out there that look different (some have a speaker on the front some don't)... Ok i understand different branding... what not... (I have the T-Mobile Version)

"T-Mobile uses a 1.5 GHz dual-core Snapdragon processor, as opposed to the 1.2Ghz dual-core Exynos processor. While the 1.5 GHz clock rate is higher, that may not translate to higher performance since it uses a Qualcomm Snapdragon MSM8260 (S3) Scorpion instead of Samsung Exynos Cortex A9, with different cache sizes and different integrated graphics architecture (Qualcomm Adreno 220 instead of ARM Mali-400). The reason for this is that the Exynos processor is not compatible with T-Mobile's 42 Mbit/s HSPA+ network."

Ok sure but does that effect rooting/roms/ect...???

Its running the same OS so the processor doesn't matter correct?

And Lastly am I doomed working on a Mac?
[Galaxy S II Q&A, Help & Troubleshooting] TheSniperFan:
Yes, the roms/rooting-techniques/kernels are not compatible to each other.

When it comes to the question whether software works with a specific hardware, the architecture and special features matter in the first place. It's a complex story, but shouldn't be a problem here.

As for your Mac:

Why should you be doomed? A Mac is an ordinary PC (despite what apple-fanatics say). So, no, you aren't doomed because of this. However, there might be software that's not available vote OS X.

Then you have two options:

1. I'm absolutely sure that there it's a way of making Linux-applications run under OS X.

2. Linux is free, so you can download and dualboot it on your machine.

I'd recommend you the latter, because when it comes to flashing my brand new phone, I don't want to run into problems, because the software doesn't run properly on an OS that it never was meant to run on in the first place.

Question regarding rooting - yet another one...!

Greetings! Yup, another noob, feeling a bit lost, redirected to the general forum to ask questions :) paraphrasing soraxd, i guess this is the place for "qing", hoping for "FA-ing" haha

I guess i have a "simple" question. I would like to root my SGS2. The thing is, i have no interest in changing the ROM (unless someone in here tells me it is something essential i should definitely do!). My phone is locked to the portuguese Vodafone network (the main reason why i want to root it, so i can unlock it)

I updated it "normally" (via automatic phone update) to the 2.3.5, so now i have the following versions:

PDA: I9100BUKI3F

PHONE: I9100BUKI1

CSC: I9100TCLKI3

build info: wed sep 28 ... kst 2011

from what i have read, i need to flash it with a specific insecure kernel. My question is, how can i restore my original stock kernel? Or can i keep that "insecure" kernel? Can i use kies to update the firmware normally even with that kernel? What about it i want to send it for repair?

grateful in advance!

after that I used JIG to remove the triangle.

after that I installed some apps and among them newest busybox. today by change I read CFs thread for 10th time and see that he recommends not to install busybox cos it's already inside his package and that something can get messed up.

so how to check now if I managed to messed it up? It gave me some error during installation of new busy box, I think it stated that there already is busybox inside...

if you want to replace the stock kernel you'll find it on this forum, look for it with "search", if you update the firmware with kies you'll lost the root. for you to get your phone to repair, you'll need to get it back how it was from the stock, kernel, rom, everything, there is an other thread for this too, use "search".
