I RMA'd my device and need to reset the tamper flag. I followed the instructions here in the forums, but it is not working. I've tried 2 different methods.

1) Download the flashable zip file and use fast boot to boot into TWRP. The problem with this is that once i boot into TWRP, it does not recognize any files in the sdcard/downloads folder.

2) Download boot unlocker from the playstore. I need an unlocked and rooted device so this seems pointless as I will need to unlock and relock my boot loader to use this.

Someone please help.

Re-root the device with TWRP. Then download bootunlocker and reset the tamper flag. Then flash the factory image, relock the bootloader, and you'll be good to go.

I followed that video and it did not work. First off, I can't find that zip file anywhere. The link on the xda forums doesn't give me the correct file. Second, I have a mac. For me to boot into TWRP using fast boot, it required the boot loader to be unlocked. If I unlock the boot loader to boot into TWRP via fast boot, TWRP doesn't recognize any files in the downloads folder.

Bro,
1. Flash the factory image in fastboot
2. Download the latest TWRP recovery and rename it to twrp.img and put it in the fastboot folder and download this zip http://forum.xda-developers.com/atta...3&d=1387666907 and put it on the phone`s sdcard.
3. Go into bootloader mode and flash the downloaded zip in recovery, just type in cmd: `fastboot boot twrp.img` and you`ll boot into twrp recovery.
4. Done, you`re device is locked and the tampered flag is reset.

Oeps saw you have a Mac so look here:

Wrong order bro, and why would you have to reroot to flash twtp as long as the bootloader is unlocked. Once the bootloader is locked you can`t flash the image anymore

Because you need root to run BootUnlocker in order to reset the tamper flag. Resetting the tamper flag is the first thing you should do, relocking the bootloader is the last.

You don't need root for that bro and relocking and resetting the flag goes in one go with the bootunlocker script at the end.

The OP stated he couldn't get the script to work or didn't know how. My advice was that he use the app instead.

Oke, initialy i thought he had a windows PC and saw later he had a Mac. Does the Bootlocker app also reset the tampered flag? Haven`t used it myself yet.
