Flashing from the beginning - Galaxy S II Q&A, Help & Troubleshooting

Hello everybody,
My girlfriend has a Galaxy s II with a custom rom.
Now she wants to another rom and by my phone I always start stock.
Which stock rom must i use for her phone to get to 2.3.6 JVZ?
It's a Europe Telephone. Thanks in advance!
Greetz,

You can jump from custom ROM to custom ROM without going to stock first.
If you have a custom ROM with ClockworkMod, you can flash a new ROM from there (be sure to format /system and /data to avoid problems).
If what you want is to revert to stock, you can find stock ROMs and instructions in the Android Developement forum.

Hello,
So it's not really needed to begin from the stock? Not better for the next rom?

no, it doesnt matter

[Q] Got my Samsung Galaxy S2, now what?

Hi there,
Today I received my Samsung Galaxy S2 and now I'm trying to find some information about custom roms for my phone. After searching through all sticky's here I cannot find any info about where to start with custom roms.
My previous phone was a HTC HD2. I've installed android onto my phone using MAGLDR and Clockworkmod, which worked great. The thing I liked the most was that in case I screwed up a installation I could alway flash the original Windows Mobile ROM back, making my phone almost stock again(still will have to remove HSPL then).
I also helped a friend install custom roms on his HTC Desire HD, but the thing I notest on that phone was that you could never go back to the original android installation. I hope this is different with my new phone.
So these are my questions:
- Where can I find some information about flashing a new ROM to my phone?
- And is there a way to revert back to the original ROM after using a custom ROM?
Grtz Willem

First root your device.
Then:
Flash a rom which you can find in the Development section. Every big rom has their installation procedure explained. (VillainRom, Cognition.. dunno)

You can just flash back the original stock rom, but there's a hidden counter that counts how many times you flashed new software. You need a little tool called a 'usb-jig' to completely undo the number the counter is on. This way you'll retain your warranty.

How?
Clockworkmod? If so, where can I find the ROM?

Nope, with Odin. You can find the Programm and the rom together with instructions on www samfirmware com
Thanks everyone, I'm downloading the original rom now, then will try my first custom rom for the SGS2 (VillainROM 3.0.0)

help flashing roms

Im new to the whole SGS2 so needed a little help ive rooted my Galaxy and its on UK 2.3.5 stock rom my question is can i flash any rom i choose or is it like when rooting it when i had to get a kernel that matched.
The other thing is, is it worth buying Odin Mobile.
Cheers
Once you root your phone and have CWM recovery and not the stock one you can flash any ROM you choose.It has nothing to do with kernels but each ROM is based on a firmware so you should match your firmware to a ROM based on the same to start with and if you choose to stay with the same ROM then there are non-wipe ROMs that can be flashed over top without worries.Just be sure you read properly the install/flash instructions.Some ROMs need Odin to be flashed but most just need to be pasted to your internal-SD and then flashed in recovery mode.Ill leave a link below to my ROM where there is an instruction guide so you can read it to see what I mean.

It depends on how you have rooted ...... if as mentioned above you have CWM (means you have flashed a custom/insecure stock kernel) just flash a ROM with CWM Recovery like any ZIP but i'd advise you to reset the phone before that .... since you are on Stock ROM which is Odexed and all custom ROMs are deodexed you might end up in a bootloop also may i suggest CheckROM as it is simple to install and highly customizable thus i recommend this as your first flash......

else i use this site it's pretty awesome to keep track of things

Cheers to both of you, i think i will give checkrom ago as theres that many to choose from and im new to the rooted SGS2.

[Q] ROM/Kernel

hi guys,
i'm new here so i don't know how everything works,so i could use some help.. i've recently rooted my phone using CF-ROOT 5.0 XWKJ1 and i'm a bit confused what to do now.. i wan't my phone to run on newest stock firmware, which one should I use ? the most recent one in intratech thread is XWLA4 (phone is XXKI4,just like mine,so it is for my phone or what does it mean? ), can I just flash it to the phone ? can i do it through CWManager app ? and i still don't entirely understand the difference between Kernel and ROM, I'd also like to try the cyanogen mod,what should I do first ? and how can I flash back original stock rom ? because cyanogen is 100mb and original rom is 8, so I'm not sure if it will restore the phone to the stock state after flashing stock rom back.. and yes, I've read the guide to GalaxyS2 and Android,but still do not understand everything..
thank you guys for your effort.

You need to start reading the guides your questions are all answered in the relevant guides .
You want CM you follow the instructions for CM you want xxx you follow the instructions .
ROM is firmware kernel is part of the firmware that interfaces OS and Hardware .
But suggestion is to wait for release of ICS .

Take time out to read the guides as it'll help you out.
XDA is a development forum and requires leg work!
Not only that it'll stop you joining the many others in "I haz a brick"

Download your original or stock firmware and save it .Or just simply keep a copy of the file you flashed 2.3.6
Also which stock Rom to put and which is newest i mean on gingerbread not on ICS, and that rom i want to be more aware in battery saver thats my needs for now. And also if I put stock newest rom than also i need to flash the kernel or not???
Roms have kernel built in .
And whats the privilegies if I flash the kernel to??
Fail to understand are you confusing kernel with firmware or with a rooted kernel .
I help couse this Samsung G SII isn't mine, it's my cousin 's phone, so last thing. Is to brick his phone.
Honest opinion is you dont have enough knowledge to flash a phone that you do not own what are you going to do if you brick it buy him a new phone .

How do i get back to original rom

hi guys,
i have a samsung galaxy s2 (GT-i9100 - NFC), which i got from orange end of 2011. I the in jan 2012 got help from this forum to root my phone and change the rom from the original to:-
Rom & Build No: VillianROM 3.0
And' ver: 2.3.5
Baseband: i9100XXki1
Kernel: 2.6.35.11-ninphetamine-2.0.5+ninpo @ titan #20
Although the phone works okay, i'm beginning to notice a lot of slowdowns and regular reboots, so i want to go back to whatever latest google android OS the S2 can handle (rooted). I've forgotten what to do and would be most grateful if someone could please help me with the following:-
1. Whats the best software/method to backup everything?
2. What is the latest rom (original, but should not have a provider's bloatware) i can use on the S2?
3. Once backed up, how do i change from VillianRom to the latest/best OS currently available?
4. How can i root the original rom?
Thanks once again

For official stock rom, check
www.sammobile.com
And search latest stock rom for your region.
If you like custom rom, then there are so many roms on xda. I like omega and alliance roms. Choice varies from person to person

1. Depends. You can do a backup in CWM to image your device or you can use Titanium Backup Pro to just backup your apps/appdata and restore to new rom.
2. http://www.sammobile.com/firmware/ < Check your device/model here.
3. Well just so you're clear, There is no "best" its subjective. Also "latest" depends on what type of rom you want to flash like Sammy/AOSP/AOKP/CM/MIUI etc. To flash latest samsung do it via ODIN, to flash any other do it via CWM. All info you need is already on forum.
4. By flashing custom kernel via ODIN.
All your questions have already been answered countless times.
Thanks very much guys. I simply want a fast lean rom as some seem to be slow running.
Doesn't get better than this.
sendign the phone for warranty?
you will need to flash back the original rom and unroot your phone.
if they found your phone is rooted the warranty void, experience it before so be aware of this.
Let me thank you guys for advicing me. I am most grateful. I read your posts a bit late and in the meantime, I think i have bricked my phone as i've flashed Samsung's original FW (I9100PBVLP8_I9100PORALP8_ORA) from sammobile.com. I used Odin v3 and successfully flashed the phone, but it's simply stuck on the boot logo. I have even done the following:-
I've managed to wipe the cache partition, but the recovery menu has No advanced options. It says:-
ANDROID SYSTEM RECOVERY <3a>
reboot system now
apply update from ext' storage
wipe data/factory reset
wipe cache partition
apply update from cache
test redband fota[FS]
But i still cannot get it to boot. I have also tried to use an old nandroid.md5 backup i made, but odin reports the file as invalid.
I'm desperate guys, please could someone help me.
Download Mode and re flash.
Are you sure you are flashing the right ROM right? Check under the battery to see the Device Model.
If it's i9100, then make sure you are downloading a i9100 ROM.
Thanks very much for your advice gastonw - i have managed to fix the problem now by going into system recovery and doing a factory reset, so thank you.
Although everything seems to be working fine, i would have preferred a more newer 4.2 jelly bean rather than 4.0.3. Oh well beggars can't be choosers and all that, lol! I guess i'll have to re-root it again.
gastonw mate ur a star! I've installed the latest JB rom u posted earlier and i'm very happy with it.
Now before i damage it beyond repair, how do i root it safely?

Hi You could try this method http://forum.xda-developers.com/showthread.php?t=1501719 its quite safe so ether should work or wont, if don't no harm done as it doesn't need a insecure kernel.
I'm quite new myself @ this so plz use caution when trying it out.
Peace

Good to know man, enjoy it
About root, I've seen a couple of methods laying around the threads, I'm sure they're safe.
I still think that ExynosAbuse app is the fastest way to Root now (one-click).
Here's a vid. I never tried it tho.
Thanks very much for the links AnubuRe and Gastonw.
Gastonw mate, i have been playing with the rom you posted a link to. Don't get me wrong, it's great and very fast, but the downside is that it doesn't have a huge number of options to tweak etc. Now someone mentioned a rom called Neatrom, but i'm wondering what you can recommend? I don't want a bloated rom...i want a fast rom, but with some options to allow me more greater control over the phone.
Also, i know this is a bit off-topic, but can you recommend me a widget app, where i can quickly dial phone numbers i.e. by touching a person's photo?
