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.

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.
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.

Ok...so I've been reading almost every post in here all day long...and I wanted to upgrade my Stock Android 4.1.2 phone to one of the cool roms on here. One rom (I can't remember which one)...said I needed MJ9 firmware...so I flashed it. Then I successfully rooted. I then tried to install a new recovery so I could flash the new shiny rom. As soon as I rebooted...got the Verizon Brick Message from hell. Ok...then I searched how to get rid of that. I found a post saying to flash back to stock MJ9 which gave me Android 4.3. Now that means I can't unlock my bootloader so I could root and install the roms...correct?
I guess my question is. Can I use ODIN to flash back to 4.1.2 and have a chance at an unlocked bootloader...or am I skrewed? I should just accept the OTA kitkat and be done with it?

Well if you flashed stock 4.3 you most likely locked up your boot loader and there is no known exploit to unlock that boot loader atm. I think there's still a way to root 4.3 but I'm not 100% sure how. Hopefully someone else can chime in on that.

Unfortunately, your bootloader is locked now, so trying to ODIN to 4.1.2 won't unlock it. There's not an easy way to unlock it now (search the threads and you'll see that Mobile Tech videos can downgrade for a price... and someone else reported that they used an "unbricker" method to downgrade... but others don't appear to have had as much success).
If you stay on 4.3 MJ9, you can still get root, run root apps/ Xposed, etc... And with 4.3 MJ9, you can also use Safestrap to run custom Touchwiz ROM's.
If you take the OTA to kit kat, there's not a root method currently for our Note 2's, so you'll be running pure stock.
It's totally up to you, but if you want root (at least for now), you'll want to stay with 4.3 MJ9.

Hi!
As stated above, I tried updating to the Kit Kat Release for Portugal's I9205 from an asian I9205. Testing out the device, mobile data won't activate and gives me a "Please Insert SIM" error. Because of this, I wanted to roll back to 4.2.2 but seem to be encountering an error in ODIN, primarily one that says "Check Fail Fused 2 > Binary 1".
My question is, how would I be able to revert to 4.2.2? Any help would be appreciated.
Thanks!
Unfortunately, upgrading to KK is one way road... after installing KK there is not possible to downgrade because of new bootloader and efuse in kernel. If you want to go back to good old 4.2.2 let flash MegaFireV10 ROM from @ megalomanic14 which is greatly improved stock 4.2.2 and is already rooted. I could be flashed onto KK without consequences. Simple flashing back stock 4.2.2 could make your phone brick.
Oh, so there's no way for me to roll back? That sucks!
If I flash a new custom ROM, like LiquidSmooth, would my ability to use my mobile data be restored? What's affecting it at any rate? The Modem? Is there anything I could flash that could help?
Would restoring it via KIES work?

You'll be pleased and just May get your mobile data restored!

I did a Nandroid backup and restored that after trying NE4. The only change is the baseband is now NE4 but I am back on MH2. Is this not normal?
Hello, as my thread title suggests I have a question about custom kernels. I made the mistake of updating to 4.3 on my device [I did it for the TRIM feature but wasnt aware of the cons Verizon put in place with 4.3], before 4.3 I was rooted and was using the stock OS and kernel. I do know that its possible to get Root access with 4.3 and Ive already done that - My question is if it is possible to install a custom kernel that will allow me to overclock this device ? I know there are a ton of kernels out there, but I dont want to risk bricking this device or having to download the ODIN 1GB+ 4.3 android file to bring it back to life..Thanks in advance!
Unfortunately, you cannot install a custom kernel. You would need to have an unlocked bootloader to install custom kernels.... and there's no current do it yourself method to unlock the 4.3 MJ9 bootloader.
4.1.2 was the last Android build for our phones where you could have unlocked the bootloader.... and so far, it doesn't look like there's going to be a method developed for 4.3.
