Hi guys!
This is my first thread post so bare with me I have a galaxy s3 rooted with CWM recovery on stock ROM. If Samsung releases a jelly bean OTA update to us soon, will i be able to flash it or will it brick the phone?
I know i can always flash a custom JB ROM that i know CM9 and AOSP are currently working on, but if i want to do it officialy through Samsung, will i be able to? Are there any risks?!
Thanks!
as long as youve used chainfires cwm ver1.5+ youll be fine to get ota updates but you will need to run cf root again after the update.

OTA's
Since v1.5, flashing OTA updates is supported directly using this recovery. You should however be aware that said OTA will most likely re-install stock recovery and remove this one. Furthermore, it may keep doing so every time you boot. CF-Root v6.3 (and newer) will try to disable this, it is advised you flash that. Just reflashing this CWM recovery will likely not help.

rooted galaxy s3 can i install factory update?
Hello from a noob
. I purchased a Galaxys3 Verizon with android 4.1.1 from a fellow that did not disclose it was rooted.
I have no idea what the steps are if I would like to do the next up date and what will happen if I do it.
Any help would be appreciated
Thanks snuke1e
You don't have i9300 so not much help here.... Find Verizon section...
Dear All,
My SGS2 GT-I9100 cannot be upgraded using Kies, it says firmware upgrade for this device is not supported. Currently my S2 is on Gingerbread. I manually updated to 4.0.4 using Odin but strangly there is this unwanted information stucked to the homescreen regarding my CSC and everything. Another user on this website also had the same problem and he posted a picture as well. (http://forum.xda-developers.com/show....php?t=1876539)
I have done everything, flashed many different countries versions of android 4.0.4, cleared every memory, fixed the "/efs/imei/keystr" but in vain. The information is stucked there. However, when I flashed 4.0.3, the unwanted information was gone. Can anyone tell me why I can't use Kies to upgrade my phone or why is this information there? Any help with this guys?
Thanks
Yasir

Then stick with 4.0.3 and wait for official 4.1.2.
Hi,
had my S2 for a while now and installed ICS through ODIN as here in NZ the updates seem to come a little slower than the rest of the world!
but id like to be on Jellybean and heard so much about unsafe Kernels etc (most of it goes over my head haha)
but i figure my best option, as i dont want a bricked phone, is to go back to stock and get my updates the old fashioned way.
what is the best way to do this? i know other phones can do this through KIES itself...(entering a serial etc), does this work with all phones?
any help would be greatly appreciated!
ICS 4.0.4 stock kernel has brick bug. If you are on stock 4.0.4 then avoid any kind of wiping. If you want to flash official JB go here
Hi friends I own Galaxy s 2 i9100....I got it from UK 3 mobile.. After coming to India I have flashed it with a ROM which is unlocked version as its is locked to 3 network...after the flashing I connected it to kies for backup and found the same message as others in this thread mentioned...so I tried reflashing it with a ROM that is compatible with Indian version and got the issue solved ...I am providing the details of the rom now I am using
PDA: I9100XWLQ2
phnoe: I9100DDLPC
CSC: I9100ODDLPD
BUILD info: Fri oct 26 16:04:15 KST 2012
But recently KIES software in my laptop got updated and when I connected my S2 it stated that my phone is not compatible to update from KIES. But, the same day when I connected wifi in my phone I got a message that an update is available and its done successfully.
Now can any body help me to get that issue sorted out when connected to KIES as it accepted before and now why it is not accepting ??
Thanks in Advance

thankyou! very helpful...now that i have read that entire post i just have one question....isnt that still classed as a wipe? the first thing it says to do is put your phone into recovery mode then wipe?
Flash Siyah or Dorimanx kernel first (without wiping ANYTHING). Then use the CWM that is installed with either of those to...
A) complete the wipe processes. And
B) flash your chosen stock ROM.
When you flash your ROM, you WILL overwrite the Siyah or Dorimanx kernel you previously flashed as your ROM has its own kernel (and CWM). As things stand at the moment, this is probably for the best because there have been some changes to CM10.1 that have made a lot of standalone custom kernels incompatible with the ROM..... for example, I lost my baseband when I flashed Siyah on top of CM10.1 and I'm told that there can be issues with video recording too. Which brings me to make one more point....before starting any of this...
MAKE A NANDROID BACKUP....
it's your safety net if it all goes wrong (personal experience is a brilliant teacher lol).......

I recently tried to downgrade my Galaxy S3 from Jelly Bean 4.1.2 to ICS 4.04 using Odin and a ROM file downloaded from Sammobile.
The installation was succesful and after doing a factory reset and clearing cache the phone booted up ok. It connected to my network provider for several seconds and then disconnected.
After several attempts at this process using different files, I noticed that the IMEI of my phone was no longer correct. At this point I thought I had bricked my phone by somehow corrupting the IMEI.
In an attempt to put it right, I reloaded Jelly Bean 4.1.2 and my phone now works fine again. Please can someone advise what I am doing wrong with this process and why the IMEI gets corrupted as this is obviously why the network rejects my phone when I install ICS.
If you would look here: http://forum.xda-developers.com/galaxy-s3/general/ref-galaxy-s3-modem-radio-collection-t1740061 you will found this link for ICS ROMs: https://www.wuala.com/UpInTheAir/SGS3/Modems/I9300/ICS/?key=n0KVwtIMZPE8 . From here, select CWM folder if you want to flash the modem via recovery, or the Odin one if you want to flash it with Odin. Choone one of the file, download it, and then flash it via the method you want.
QuickQuestion: Why would you wanna use ICS when it has been released 4.3 for our device, and 4.4 it is said to be released in the following weeks (Hope so! ). If you want, you can answer, if not, it'ss not a big problem
Thanks for the reply. Is this the reason my IMEI is corrupted when I flash a PDA from Sammobile? I am new to using Odin etc and followed the instructions on the website.
There are some features I liked in ICS that were removed in Jelly Bean, such as direct access to words in the custom dictionary and the 3 x 4 keypad that was removed in 4.3. I already downgraded from 4.3 to 4.1.2 but wanted to try ICS 4.04. So far I can install it but cannot get a network connection for more than a few seconds.
#EDIT: After further research this problem appears to be an issue with the phone's EFS data. I have now used EFS Professional to back up this important area. What I don't know is can I restore this backed up EFS data to correct the problem I'm having when I downgrade Jelly Bean 4.1.2 to ICS 4.04?

If you have a 16GB s3, u might want to keep JB, 16GB ICS S3 has the possibility for sudden death. But, i too am considering going back to ICS, Jellybean is a joke, it lags way more than ICS does. Trying to force the system to constantly render at 60FPS is hardware demanding and was probably a temporary approach. Its unfortunate that ICS ROMS are no longer available for download. Also, i doubt kitkat would be released for our phone.
My S3 is 16Gb and was originally shipped with Jelly Bean. I watched a Youtube video comparing ICS and Jelly Bean and ICS was faster responding in virtually every test, despite the guy doing it being pro Jelly Bean.
I don't know much about the 'sudden death' problem with ICS on 16Gb models but from what little I've read, I thought this was more of a hardware issue due to defective memory chips and/or main boards?
My S3 updated to Jelly Bean 4.3 last December and I wasn't happy because they had removed the 3x4 Samsung keypad that I like to use. I tried a number of different keypads from Play Store but in the end decided to downgrade to 4.1.2, which went without a hitch.
My attempts to do the same with ICS 4.04 did not go so well and I'm still not sure why the IMEI was corrupted or even more surprising, that it was corrected when I re flashed 4.1.2

Not sure exactly how the sudden death works, i just know it affects 16GB s3 variants. I know the video you are referring to, i watched the exact same one. I think most people got caught up in the hype of JB and forgot how good ICS was.

The Youtube video made me laugh as it was supposed to encourage you to want the Jelly Bean upgrade, when all it did was make me want to run ICS even more! I tried a friend's Galaxy S2 with ICS the other day and it was smoother and faster responding than my S3.
I hope to have another go at getting it working but also I am concerned I probably came close to bricking my handset last time because I do not know enough about the process. This wouldn't be good as I still have another year on my network contract to go.
Do post here if you succeed in downgrading to 4.0.4 as I am also looking for it but it's not working
And best of luck
Unless you have a backup of your efs folder, from before firmware EMG4 then you cannot downgrade.
EFS format was changed at EMG4 to v2, earlier roms are incompatible with v2 and later roms incompatible with v1 so IMEI will be corrupt.

Thanks for the info.
My S3 was shipped with EMG4, so unfortunately I don't have any efs data that I can use with earlier ICS firmwares. I was trying in vain to load BLG8 but it just resulted in a corrupted IMEI and no network.
Unless there is some way of converting saved v2 efs data to the earlier format, then I will have to stick with the Android version I have.
Why are you not trying 4.3 or custom rom mate? My god if your phone is giving u problem u should try to tame it. Very smooth, the nb6 firmware. Or at least let yourself try a custom rom for instance temasek.

I have tried the Official Samsung 4.3 release but didn't like that they removed the 3x4 Samsung Keypad, which I prefer to use. I've tried custom firmwares on my old phone (Galaxy Ace) but never had much success with installing them or getting things to work properly after.
My S3 is still under contract for another year and my skills in this area of modifying are beginner level at best, so I plan to do a lot more reading on here and a lot less messing around with the phone firmware until I know more about it.

Your phone lag is because of Samsung bloatwares, get rid of it and you would be fine. Temporarily suggestions would be hang on 4.12 and try greenify. U don't need root but root would give you he best out of it. Look up cf autoroot and begin your journey.

Flashing the original firmware via Odin does not factory reset the phone (unless specifically stated in the thread containing the files). It just overwrites the bootloader (depending on the firmware and phone), recovery, system, modem, etc.

Hi
How to re install my S2 with Jelly bean . Planning to install Kitkat in my S2 can you help with any good Download and install links. Its good to install ??? please suggest Thank you .. I will check your website
I'm confused on your goal. You want to install Jelly Bean or Kit Kat? There was no official Kit Kat for your phone, so it will have to be something custom like CyanogenMod, SlimKat, etc.
The latest official firmware for your phone would be here: http://samsung-updates.com/device/?id=GT-I9100 - Just make sure to get the one for your region.
