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:0/008> FAIL! (Auth)

CWM Recovery.img flash issue:

<ID:0/003> Firmware update start..
<ID:0/003> recovery.img
<ID:0/003> NAND Write Start!!
<ID:0/003>
<ID:0/003> Complete(Write) operation failed.

Research status: 10%

+ 10% - phone rooted trough system.img tricks -> http://forum.xda-developers.com/showthread.php?t=1756885 (by invisiblek)

ROM analysys:

boot.img -> signed
recovery.img -> signed
system.img -> not signed
cache.img -> not signed


Update [7/7/2012]

News about locked Verizon model is spreading over the websites and main tech-related portals. Hopefully we will get some detailed info soon.

Update [7/7/2012]

It looks like it has been rooted by using system.img trick (system.img is not signed)

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?

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.

I got into Odin download mode by holding volume down, home and power. I had to do it about 3 times before I got it right. However, that was for another purpose, and I have NOT tried to flash this image.

it was a yellow triangle on older phones, the green android is correct for the GSIII, that's download mode, how did you enter it? i see above others have done volume down, home and power together....updated my OP

Holding volume down/home/power should bring up the green triangle. Then you press volume up to go into Odin mode.

Sorry jamesnmandy, I misread your earlier posts. I thought you were suggesting other methods, not that you were asking how to get to download mode on the s3.

nope, no problem, I found it was probably going to confuse people so i edited it to reflect the correct method for the GSIII, thanks

You need to be in download mode, then connect phone , put kernel.tar as PDA and flash.

Report any issues, i dont have this version of phone. It will not break it, in worst case u will need to flash oryginal kernel (which you can take from full stock rom post).

    I might be able to help

    I have a strange phone

    http://forum.xda-developers.com/showthread.php?t=1754173

    I was eager to try and flash that insecure image, but perhaps its better I didn't.

    I don't know how to dump what I have, but I'm willing to do it if someone can instruct me.

    Locking until cleaned. Go discuss this in general. OP, PM me with any questions.

    Edit: Cleaned. Discuss the bootloader issue in the very obvious thread in General.
