[HOWTO] [ROOT] Reset Flash Counter [Confirmed VZW, Assumes others are the same]

---

So, you managed to trip the flash counter.

Here are the commands to reset the flash counter. This works on my VZW rooted phone. Since all of the other variants have a very similar (same?) partition setup, this "might" work for them as well ("might" is the key word).

I take no responsibility for you voiding warranty.

I used this post as the basis for my theory and then used my phone as the test for said theory: http://forum.xda-developers.com/show...0&postcount=67

The "'\x00'" portion tells it what resets it to 0. If you wanted to be funny, you could set it to a different number.

adb shell
su
echo -n '\x01' | dd obs=1 count=1 seek=4193796 of=/dev/block/mmcblk0

I can only confirm that this works on the VZW variant. Until I get some dumps of the other variants, I can only assume it will work for them.

TRY AT YOUR OWN RISK!!!!

This is great news! Is there a way to read the value to confirm it's been incremented? (I have an AT&T phone, and would like to confirm the value is 1 right now - which is my current flash count).

Sorry, I might not have worded that correctly. I'd like to read that memory block that he's proposing we change and see if the value stored is the same as what's displayed on the Download screen (which I can see). Basically, as I understand it, his command will reset the counter. I just want to confirm that on an AT&T flavor of the phone, the results of that memory block are the same.

I think this will work:

dd bs=1 count=1 skip=4193796 if=/dev/block/mmcblk0 2>/dev/null | od -t

Actually Chainfire just released v1.70 of Triangle Away today that resets the counter on the US/Canadian variants. Not sure if he used the same method as the OP here, but thanks for your research into this as well!

Not seeing that release got a link?

In his main thread - http://forum.xda-developers.com/show....php?t=1494114

can anyone confirm triangle away or this method works on ATT version of the s3?

I'm about to try it on my AT&T, but he does callout our version as being supported in his latest release. Wohoo!
