Hi Guys,

Verizon model is protected from flashing unsigned/modified boot.img and recovery.img. Which means there is no known root method as for now for SCH-I535.
Stay tuned for more informations as we are doing research now.

Rooted stock boot.img issue:

<ID:0/008> Firmware update start..
<ID:0/008> boot.img
<ID:0/008> NAND Write Start!!

<ID:0/003> recovery.img

Enjoy! and thanx to invisiblek good job!

Thanks!

well brother, i have already run out of thanks for the day, but thanks

have you seen any flash failures in Odin on the GSIII due to battery being in or out? With the Charge you had to have the battery out while entering download mode, then immediately place battery in before flashing or it would fail everytime.

Also, how exactly do you enter download mode for the new guys?

fails here...

fail

suggestions?

Everyone is using the latest Odin provided correct?

Same as the last two posts. Failed twice.

correct, and teh phone is telling me secure check fail ; boot

I am going to have to ask again.....what exactly is the process of entering download mode? Do you have to pull and replace the battery at any point in order to avoid failed flashes?

Updating for GSIII

1. Turn off phone
2. connect USB cable from PC to phone while holding down volume down button, home button and power button simultaneously until android logo appears
3. press volume up button
4. see that Odin detected and connected to the device
5. flash file using PDA button
6. profit?

I was unable to get the phone into download mode without the battery in. I tried volume down/power as well as volume down/home/power while plugging in the usb cable. All I ever got was a single vibration but no warning triangle.
