Start with a ROM of your choice, just pick one you'd like to try and test it out. If you don't like it try another one out.
*Repeat untill your phone dies

Hi Vinay, Post ur questions in Q & A forum. Ok the difference between custom and official ROM is u ll get ROOT access, many mod from official. Moreover check the caution lines before flashing any ROM.. Watch some videos on flashing ROMs. Also always a copy of main original official ROM..

and a nandroid backup would be also useful just in case something goes wrong

Hi!
Custom rom made by developers that can be from stock (samsung) basis or aosp/aokp (google) basis according to what the devs wants and need, so you need to know about what features and themes are included in the rom so that it would match your preferences. There's sure are a lotta rom out there to try. Be sure to flash only rom that made for your phone and made a backup just in case..
Happy flashing!

Hi to all and thank you for helping me.
The big trouble is that i led my phone in to strange state where only triangle appears and logo of samgung and gets stuck in that state ;after downloading some wrong ROM, my mobile got to this state , now i want to get back in order to wakeup my mobile and brings it too original state as pervious , also to inform you that the mobile was locked to local operator and i tried to unblock and i did mistake .
I just want to have brief guide to how to start as there are many information in this forum and i dont know which tutorial should i base ON.
Basically i just want to know which ROM should i take and procedures in order to install the correct ROM in correct way. I allready has the ODIN installed in my PC and at the moment i can navegate in my phone by Clockworkmode but i dont know what i should do after that , i do know that i can put the ROM in SD Card and try to force the mobile but first i would like to have exprties opinion on this matter, PLEASE.
Regards
Vinay

Well basically if you want to restore to original state, you have to flash the stock rom for your phone or the backup you made before (which I assume you didn't made it). Try to find the stock firmware/rom for your phone version/country/region on sammobile and flash it using odin (put your phone to download mode first). Hope it helps..
P.s: don't worry about the yellow triangle thing, it'll disappear after you flashed the stock..

Thank you sir and thank you all moderator helping me on this ,
Ok ;i understood but if i dont want to go back or lets say if i want to root and unblock without original stock ROM what procedure should i do , please.
I am also having difficulties finding the best ROMS for mobile S2 GALAXY where i should find them , please.
Best Regards
Vinay Navinchandra

Dont mention "best rom" since its against the rules.Youll get a warning and your/this thread locked.

Yeah, it's a matter of preferences if you talked about what best so browsing around and try for yourself..
Some custom rom got pre-rooted, and some need to be rooted first or even not at all. There's lotta method to root sgs2 and it's not hard at all, just google it and you'll get it..

help with my new s2

i am from galaxy mini forum so get a galaxy s2 but how to know if it is S2 or S2 GT-i9100 o and what the diffirence?? and can you gays pleas link me to a tut aboug instaling costome recovery, which ODIN to use and so on .... last thing which is the best stable rom to use .....thanks in advance
1) Check the sticker on the phone chassis under the battery.
2) Differences between SGS2 variants ? Wikipedia.
3) Just about everything you need to know to get you started is in the Stickies.
4) There's no such thing as the "best stable rom to use". There are a heap of custom roms for the SGS2, it's an individual preference thing. And because no two people use their phone the same way or have it setup the same, and because component-wise no two phones come out of the factory exactly the same, your experience with a particular rom will most likely vary from mine.
The best thing to do is to get your phone rooted, preferably with CWM installed. This will enable you to backup, restore & flash roms/kernels in a matter of minutes. You can than try a bunch of roms for yourself. If you find you don't like a rom you try, it's easy to go back to your previous setup easily by restoring a backup; recommended regularly/before you flash anything to your phone.
ok so by flashing cwm and then a costom rom the divise will root by it self and do i have to flash a stock ics rom to install a costom ics rom??????
Lackchoo,
Flash one of Chainfire's kernels. His instructions are very clear. That will give you root and CWM, and possibly also a yellow triangle at startup which you shouldn't worry about at all.
You don't need to flash a stock ICS ROM to flash a custom ROM. After rooted, in CWM, just install the downloaded ZIP ROM file of the custom ROM. You will keep root and triangle will go away.
Ditto what the above person said about ROM's. However, you can try Cyanogen (Do a 'stable' release, not a 'nightly'), its the most 'popular' ROM in terms of numbers. One can't and shouldn't say which one is best. But for a newbie, I think Cyanogen is a good place to start. Perhaps it will give you the least issues and the most 'oohs!' for your initial newbie effort
I don't have the links with me from the smart phone, but just search 'chainfire kernel root galaxy s2' and 'cyanogen galaxy s2' and you should find the relevant thread. Read it slowly and repeatedly! I know I had to

[Q] ODIN , Mobile ODIN, or CWM

Like title ask, wich way for flashing new firmware is safest?
But wich way is better for device?
And wich way is cleanest (dont stay bargabe files from previous version, etc) ?
Any way, write dear member yours opininon abot this diferent ways flashing ROMs.
Regards
Rom flashing tool depends upon the rom instructions not on what you like .
None are of less risk if instructions followed .
jje
- for mods and stuff i would use TWRP or CWM
- i perfer odin for flashing stock.
...it's up to you.

If you want my 2 pence worth of an opinion...
Never touch Odin...lots of possibilities of something going wrong and very difficult to recover...
Don't know about Mobile Odin..never used it..
Custom Recovery FTW...generally ROMs or mods interact only with the system, data and boot partition and hence the probability of anything messing up with the EFS partition and Bootloader is minimal..however Odin interacts with the Bootloader while flashing so the chance of it getting screwed are larger..
However, It is me and I like to see what I am flashing..(which is easier with CWM)..so that I know what may go wrong...

[Q] Where to download stock ROMs

hello people,
i do not know anything about phones ..i am not savvy at all.
i just bought a galaxy s2 (sph-d-710) and want to WIPE AND DELETE everything and do a CLEAN install of a STOCK ROM of Android 4.2 or 4.3. (sorry for the CAPS, but it seems that in my last post people did not see the keyword STOCK.
~~(when I say "stock" ROM i mean just the basic factory operating system that would come with a device bought in the store)
i dont' care which one.
I don't need to restore or back up anything. i just want a stock ROM.
So where can I find an official stock ROM for this device?
I just want to do a clean install just like one would with a laptop...wiping the hard drive and installing a fresh copy of Windows.
I searched for days on google for this topic but it seems like everyone has to be cool and do a custom ROM and nobody knows anything about factory stock ROMs.
Please anyone know where to download an official stock ROM
thanks

Problem with custom rom

Hello everybody, my device is a Samsung Galaxy S Duos S7652.
I am new at this whole rooting thing, i did my first rooting to be honest yesterday and i chose PMP Ultra custom rom, because it was the best rom for my taste.
Unfortunately i didn't know about baseband compability , and my baseband version was s7562xxlj3 , and now my phone cannot receive or make calls.
I need help, what do i do??
I cant even find my original rom so i can install that, or even a custom rom that supports my baseband..
Can you please help me?
Best regards, Alkis.

I think you are mixing some definitions.
Rooting is providing root capabilities to the phone, this is a standard operation in the *nix world.
Selecting a ROM is formatting the whole system and put a new one and you probably changed the kernel (hence the baseband problem).
Fortunately the phone is not bricked (unable to boot), so my recommendation is try to check if there are other kernels/ROMs compatible and change it.
Fortunately this showed while searching: http://forum.xda-developers.com/showpost.php?p=42182649&postcount=1708

I would recommend either restoring a NANDROID backup in recovery and if you don't have a backup I would recommend searching for your devices firmware here http://www.sammobile.com/firmwares/1/ and then flashing it via Odin. Let me know if you still have questions I'll be happy to help you out.

That's a bit of overkill if they just need the modem, unless it's not been separated out of the original full firmware to flash separately, or you need to update the bootloaders.
To dosadnik2001: Which firmware you need depends on which region the phone is from typically. Sometimes other modems from other firmwares work on unlocked phones, but best to stick with what you know should work right first.
What I do not understand is how the baseband firmware and the custom ROM are related?
I've found some post about changing the baseband firmware and there they say that the ROM doesn't care about the baseband, so you should only change it if there are some optimized baseband that can make your network coverage better. On the other side, I found several post claiming that certain ROM is not working because of the baseband firmware version.
Flashing firmware that is not for your region is again questionable for me. Doesn't this going to mess up somehow the microwave part of the phone and you can have some issues with the network carrier eventually?
Thanks.

[Q] samsung galaxy s2 downgrade from 4.4.4

The device is already rooted, you just need to download any custom ROM you want, reboot to recovery, and flash your desired ROM from there.

first of all thanks for your answer.
If I understand properly
therefore, I'll have not any problem because of 4.4.4
that is correct ?
Yes, that is correct. The device is already rooted, with custom recovery, which means you can just reboot to recovery, wipe everything, and flash any desired ROM you want.
@@[email protected]........No disrespect intended, but this is "flashing 101" basics stuff........
The fact that you are asking it, tells me that you don't have the experience needed to do this comfortably.....
That's not a problem though.....we all start from the bottom, and learn as we go.....
But that being the case, i'd advise that you don't do anything to your phone until you've read, learnt and completely understood the processes behind the flashing procedure. It's best to understand what you are doing beforehand, rather than trying to figure out what went wrong afterwards.......
