Now since that 4.1.2 Jelly Bean is introduced for a few weeks for the dutch T-Mobile Galaxy s3 phone I wanted to root it so I could configure multiview.
I tried rooting the phone through Samsung GS3 Toolkit which didn't work and I soon discovered that it had to do with that CWM (which i flashed on the phone through odin) gets automatically reset to the stock recovery mode as soon as you reboot the phone.
So I tried the following thing which should work according to this forum and several others on the internet.
- Flash CWM pda file (6.0.2.7) and make sure nothing was checked and I had to reboot the phone myself and so I could force it directly into recovery mode which should then be the CWM recovery.
The only problem is I see a fraction of a second CWM bootup but then the phone forces it's self into a reboot and so I can still not flash my phone nor root it.
So my question will be as following:
How can I root my Galaxy s3 4.2.1 Jelly Bean (GT-I9300) Buildnumber: JZO54l.19300XXELL4?
P.S If more information is needed just ask
Thanks in advance,
Paul van Venrooij

hi
i tried rooting my gs3 GT I9300 with Samsung Galaxy S3ToolKit but in stead of using the root for gt i 9300 I USED THE ONE FOR I9305 ( stupid me )
and now it's stuck and i tried going to recovery mode ==) wipe===) factory reset but there is a message telling me no os installed sure you want to wipe and after i wipe (FAILED) and still the same problem please help
Follow the guide in general, stickies to flash a full stock rom using odin. If you are very lucky it might work.
Hello,
I'm currently using a Samsung Galaxy S3 GT I9300 and is rooted through the CF Root method.
Just recently, I was backing up my files on Samsung Kies when I accidentally manually shut down my phone (so regretting this right now). Since then, my phone is unable to boot up and is always stuck at the boot logo "Samsung Galaxy SIII GT I9300". I have tried several methods such as flashing CWM Recovery and factory wipe everything and then installing custom roms but didn't work, even with repeated wiping and rebooting.
Custom Binary Download: Yes (16 counts)
Current Binary: Custom
System Status: Custom
Any help is greatly appreciated, thank you!!

Reflash the firmware via odin. Are you sure it was reading and not writing because it's odd that it won't boot.
My phone can't bootup nor boot into recovery after flashing double cwm on my Samsung Galaxy SIII mini.
The first CWM was the officail one for my phone but because i can't install zip from my sd card with it (it shows: Error! Signature verification fails.) and it has no option to toggle between signature check off/on i decided to install another version of CWM which i google search and i got one at twrp site name CWM_6.0SG3.zip. I downloaded it and flash it into my galaxy s3 mini with flashify and when i reboot into recovery my phone could not bootup. It just show the Samsung Galaxy S3 mini logo and it hooks there till i remove the battery and place it back.
Please i need an expert help on how i can delete the CWM from the phone and unroot it with PC.
Please help a brother. I just bought the phone last week, i can't afford to loose it.
Thanks.

Do you have Odin? I'm not extremely familiar w/ Galaxy devices, but last time that I was on one, stock firmware was flashed w/ Odin via a computer. Do some searching on how to use Odin to flash stock images on Galaxy devices. Your answer will be there.

Thanks dear.
I successfully flashed another recovery into my phone. Now my phone can boot up. I first made the mistake of flashing galaxy s3 CWM recovery into my mini unaware, so when I found out, I downloaded the official recovery for s3 mini then reflashed it with Odin 3.9 using my lappy.
Moderators pls close this thread.
I rooted my galaxy s3 i9300 yesterday and then installed cwm recovery on it. after that i decided to back up my device via the recovery mode, when back up was done, i got a message like 'root access lost, fix, yes or no', i chose to fix and i'm stuck with the android man screen that says 'downloading ... do not turn off target!!!'. i can still boot to recovery tho. how do i fix this?
Try factory reset but you may have to reflash your firmware with Odin.
Make sure your cwm is the latest version.

Reboot to recovery and try to re-root manually or via ODIN with chainfire cf-root.
I think you need to re-flash root via Odin
Hello everyone.
I have an S2 ( with android 4.1.2 )that has never been root and it got stock on the boot screen. I learned that I have to flash it with Odin but when I watch videos and read post, I see they mention CWM and TWRP with both need root and a working phone to install .
I will appreciate if someone could give me the steps to follow to flash my phone. Thanks
