Hello all,

I would like to gather a group of people who want to participate in towelrooting SGH-I527M (or SGH-527). If you look at https://towelroot.com/modstrings.html, you can see there are quite a lot of combinations to test and it's tedious. As this is a safe root, no harm can be done whatsoever. So whoever wants to participate, let's get it done. You'll be assigned with at most 100 patterns to test.

There are a whole lot of 1,048,576 combinations, that is 4 * 2 * 8192 * 8 * 2. But as we are not looking for temporary root and only a multiple of 4, it is reduced down to about 131,072 combinations. Let's do this. It's been long time no results!

Ok I'll be the first to report back. Interestingly, I realized tr need internet connection to work! ? as it says " please make sure connected to internet!". Also, I found that the time it takes to reboot for some patterns is longer than others.

R means Rebooted, NS means Not Supported.

The following are results:

Here are first simple batches. They all made my i527m reboot!

Code:
1337 0 0 7380 4 0
1337 0 1 7380 4 0

1337 1 0 7380 4 0
1337 1 1 7380 4 0

1337 2 0 7380 4 0
1337 2 1 7380 4 0

1337 3 0 7380 4 0
1337 3 1 7380 4 0
Here is the second batch playing with the hit_iov byte and 7380 constant:

Code:
1337 0 0 7380 0 0 R (it took a looong time to reboot)
1337 0 1 7380 0 0 R
1337 0 0 7380 1 0 R
1337 0 1 7380 1 0 R
1337 0 0 7380 2 0 R
1337 0 1 7380 2 0 R
1337 0 0 7380 3 0 R
1337 0 1 7380 3 0 R
1337 0 0 7380 5 0 R
1337 0 1 7380 5 0 R
1337 0 0 7380 6 0 R
1337 0 1 7380 6 0 R
1337 0 0 7380 7 0 R
1337 0 1 7380 7 0 R
After these two "recommended" batches, here are others:

Code:
1337 0 0 0 4 0 R
1337 0 1 0 4 0 NS

1337 1 0 0 4 0 NS
1337 1 1 0 4 0 NS

1337 2 0 0 4 0 NS
1337 2 1 0 4 0 NS

1337 3 0 0 4 0 NS
1337 3 1 0 4 0 NS
The bit at the end is pointless here (temporary or permanent rooting)... they all make it reboot too.

For future reference: tried KingRoot.net and it doesn't work. I think the Chinese guys used towelroot in their program as my phone restarted when I ran it!

Unsuccessful methods I used so far:
- framaroot
- iroot
- roomtmaster
- Kingroot
- Kingo Root

Wow, this phone is a beast!!! Later models have been rooted in a breeze, but this guy NO!

Update: After seeing this post about KNOX (http://forum.xda-developers.com/show...&postcount=207), I am so scared!

stupid question

what is the benifit of rooting without tripping knox vs rooting and having knox trip?

on the 527m canadian phone ive been tripped for a long time. honestly all my samsung phones are second hand
and i root them all with recovery and flashing supersu. and knox is tripped on them all.
im so glad that only the US carriers are locking down the phones with knox
and samsung will lose a customer when that happens in canada.

Well, I agree the whole concept of Knox is stupid. We as customers will do what we want with devices we paid for and the more they lock it down, the more aggressive and creative we hackers become! so...
back to your question, to be honest, just for test, I intentionally left one device as virgin as possible for future and testing, and believe it or not, this has been the first device that I have had for more than a few hours and not jumped to rooting it... Plus there MIGHT be some Knox software for my company, so that's why I haven't touched my Mega. I love it to pieces honestly. It's just that sweet spot. I do not care about fancy pancy specs any more. It's just a game for money and stuff... like a band wagon of $ and I'm out of it.

TL;DR: I kept this Mega untouched, to defeat the Knox tripping if I can.
