Hi,
So i've heard rumors that Samsung, soon, is gonna release an official JB update. And i would like to have it.
I, atm, have a rooted GSG2 GT-i9100 with AllianceROM ICS and Siyah Kernel 5.0.1.
So, do i have to unroot my phone back to stock, if i want to upgrade my phone to official (stock) JB?
I want to try out stock JB before trying other JB ROMs, just to see what improvements there are etc etc.
And i on SamMobile Firmware, i should use the Stock ROM for my country, right?
And also, if i flash the ROM from SamMobile, will it totally unroot my phone? Cause i still have an "not-stock" Kernel, and it isn't specified wether the Kernel also becomes stock or not.
Thank you for the time and extra thanx for replies
Regards.
It seems likely that the JB update for SGS2 variants will include some additional repartitioning of the device memory.
Unless you are really confident you know what you're doing, it might be safer flashing back to unrooted stock 4.0.4 and using Kies to do the JB upgrade 'properly'.
Then, once you have the official JB firmware and a safely repartitioned memory system you can go about rooting and restoring your app backups (but be careful with your system file backups, most of which it would be unwise to restore on a new firmware).
All this is theoretical since there is no official JB firmware out there yet.
Oh, I'm on jb leak. Won't be able to update.
hummmm.............................Got it, I'll flash.

So, I've got a UK Samsung Galaxy S3, and only recently, the carriers have started to push out Jelly Bean to the device. Only Three has done it so far, but, I'm sure my network will follow suit soon.
However, I literally have just rooted my phone. I used the guide which Chainfire provided in the forum - so, CFRoot 6.4.
I have installed CWM, and also TeamWinRecoveryProject - since I preferred TeamWin's interface, and the videos which I saw of it spoke highly of its capabilities.
So, when the Jelly Bean update does come out for my carrier (EE), will I be able to keep my root? I read around on the internet that if you have CFRoot kernel, you can still perform OTA updates (EE disabled the option, anyway, sadly) without losing root.
If so - perfect.
If not, though, would it be perfectly safe to just let Samsung Kies update the firmware? I understand it will remove root capabilities, but some people have posted about conflicts arising when flashing back to stock due to the install custom recovery.
Would it be easier to just install a ROM? I'm looking at CM10, and Paranoid Android. Both are JellyBean 4.1.2 ROMS. If I install them, would that mean that my phone would update to 4.1.2? I understand these are variations, but, is flashing a rom with a higher firmware number the equivalent of updating software through OTA/Kies?
Thanks a lot for your help! Rooting newb, here...
You don't have to think like that.
Samsung official roms are not the same than AOSP (ie pure google source based) roms, like CM, aokp, pure aosp.
In Sammy roms you'll find different framework , all the samsung apps that can't all be installed on aosp roms. You must think about what you want from a rom.AOSP ones are more fast (look at the size of downloads... between 800 MB and more than a 1 GB for most sammy roms, less than 500MB for others, even less than 200 for some), each of them have specific design and features.
You can have 4.1.2 by flashing any rom now, I think most of sammy roms are now based on latest uk Sasmsung JB. Changes between 4.1.1 &nd 4.1.2 are minimal and most of them under the water for end user.
For me rooting and installing CWM and wanting to keep pure samsung offcial rom is antinomic. The spirit of rooting is to get rid of imposed manufacturer choices.
Don't think about numbers but about features.
Well, I’ve decided to start this thread to see what the general consensus is regarding the best way to update to Jelly Bean (official) from Gingerbread (official). So basically, what’s the best way to get the latest stock firmware on an otherwise stock and/or new XT910.
Hopefully this thread can come in handy for future users, who, like me, are a bit confused and do not have access to wifi and/or official over the air updates.
If rooting is something one is after, this shouldn’t be an issue as thanks to the amazing work of djrbliss over at droidrzr.com, rooting for JB is now readily available (thread here). I will as such disregard rooting methods in this thread.
So what it comes down to is this:
- The OTA way: as described in this thread. Before installing the OTA from the ext SD Card, it is strongly advised to flash the official ICS .XML first via RDS Lite.
- The direct way: flash the official JB .XML via RDS Lite, without flashing the ICS .XML first.
- The alternative way: flash the official ICS .XML via RDS Lite, and then flash the official JB .XML via RDS Lite.
Remember, we’re talking about updating from Gingerbread to Jelly Bean.
One thing I’m particularly concerned about is bricking the device in the process. I understand that, for instance, flashing the official ICS .XML on a device that had been updated to JB via the OTA way will brick the device (no going back to previous firmwares). Is it possible to brick the device by flashing the official JB .XML directly on Gingerbread, without updating to ICS first?
Have people actually tried any of the direct and alternative ways? What do you guys think? Which is the safest/best way to update from Gingerbread to Jelly Bean?
Hi,
I have a Verizon Galaxy Note II I605 running Android 4.1.1 that I had originally rooted via Odin and followed instructions on the galaxynote2root website last Jan/Feb in 2012
I would like to upgrade to a stock ROM of 4.3 and keep root and was hoping someone could point me in the right direction in regards to which ROM to use and the steps to do so. I really only use root for the wifi tether and would like to keep the phone as close to stock as possible. I've gone through a number of different forums and posts but can't seem to find some good instructions with a corresponding recommendation on an Official OTA 4.3 ROM to use. I've found a lot variations on 4.3 ROMs, but most of them have gutted a lot of things or discussing having to flash firmware which makes me nervous.
Also, is it true I may be forced to take the OTA in the near future and potentially soft brick my phone if I don't either revert back to stock or install a 4.3 ROM which disables the update app. I'm not sure if the ROM i'm currently running has this disabled or not.
Thanks in advance for any help,

Beanstown or sophisticated rom will be the official stock 4.3, however your gonna have to flash the Official MJ9 firmware via Odin. You could take the OTA but the bootloader will be locked afterwards. There is root available with the OTA stock but you won't be able to load a custom recovery therefore no more custom roms.
+1. I did this with my note2. Was the same as yours. I'm now on sophisticated 2.0 highly recommended. I also updated recovery to Phils, which seems to be the conventional wisdom for flashing 4.3.
Sent from my SCH-I605 using xda app-developers app
had installed android 4.3 on s3 but then I installed 4.0.4 after that I had no gsm connectivity see the block sign between battery and wifi. I have gsm connectivity on 4.3 but not on 4.0.4. A guy told me that it has something to do with the bootloader. I wish to install 4.0.4 stock ICS BTU rom if there's a way do tell me. Thanks in anticipation!
Ya i tried this as well because i was really considering downgrading to ICS. IMO it runs way better than jellybean. If anyone knows how to do this, please, enlighten us. For now, just reflash the 4.3 ROM to get your signal back. As i understand it, once you go to 4.3, you need to do a downgrade, you cant just flash the ROM, if anyone can explain the process, that would be great.
For the record, if you have a 16GB S3, i wouldn't recommend the downgrade, the 16GB was subject to a sudden death syndrome and the fix is not included in ICS. If you have 32GB+ then you safe.
I have a 16 GB version of s3 I think then I should go for cyanogen

Better still flash a decent 4.3 ROM. Is there a good reason why you want to go back all the way to 4.0.4? Did you skip 4.1.2 altogether? That was better than 4.0.4, but my brief experience of 4.3, after the initial problems with the disastrous MJ9 release were resolved, is that it's the best yet.
I'd just like something that runs smoothly, 4.3 has been very slow at times.
I think downgrading is impossible, but is it possible to load up a custom rom after a 4.3 OTA update?
The only thing important is that it is an i9300, nothing else matters to flash a custom rom.
I believe I read somewhere that the OTA 4.3 update has locked the bootloader, which makes it impossible / it would brick the phone if attempted. Or is this not the case with i9300?
No.
