Rooting i757M

Am also still looking how to root this thing. The Skyrocket HD is merely the same phone, branded on AT&T carrier and this article made it clear that the phone has been silently put to the side, in favor of the coming S3. (phonesreview.co.uk/2012/05/10/samsung-galaxy-s3-buries-att-sii-skyrocket-hd).

That is, even on samsung online personal profile page, you can even find the SGH-i757M in the list of phone version, to add in your owner's page.

If anyone of you manage to root the phone, thanks to let me know.


Correction: The SGH-i757M can be found in the BAR model section on Samsung profile page and not under Smartphone. Hmm... weird categorization. Are those bar phones not smartphones? Oh, they are mini tablets.

Here is one.

Do you have any procedure to use that files? I just don't want to brick my phone

 

[rxulan]

There's no any special procedure other than flash it with Odin
There're many tutorials about it here and there like that for example.

Here is one.

Has this been tested and confirmed to work? I don't have the device yet but this may make my decision to buy one.

 

[rxulan]

dsixda, well, all I can say is that I flashed it personally (into E120L though) and it worked (including root).

Hey that is great news. I wonder if the CWM for the E120L is compatible then?

 

[dsixda]

I wonder if this works to root the device, as I've read it worked for the Asian versions of the GS2 HD:

dsixda, I guess it won't be too hard for you to check that as you're recognized developer
You can download the stock I757M firmware with the CheckFus using advanced tab (or using cli only version) with the following data:

Model: SGH-I757M
Product code: SGH-I757ZKMBMC
HIDSWVER: I757MUGLCA/I757MOYCLCA/I757MUGLCA/I757MUGLCA

 

[dsixda]

Yes, I'll try all that as soon as I get my device Always nice to have the stock Odin firmware so that I don't need to dump everything beforehand in case something goes wrong.

Thank you again

 

[dsixda]

Just FYI, the stock firmware is now available at sammobile.com. Grab an account and search for SGH-I757M. The download is much faster than using CheckFus.

Dsixda! So happy your getting this Device, I also want to say thank-you for your Kitchen you created!! Amasing work. Used it all the time with my Evo 3d.

Just got the Samsung Galaxy s2 hd lte with the Bell network, Do you have any plans to incorporate this into your Kitchen??

Also is there any easy Root anyone knows of yet that doesn't involve Odin? Like superoneclick...etc

Try the Zergrush method which I linked in the previous page.

I haven't decided 100% whether to get it, as I still love my original S2. But if I get it I will incorporate it into the kitchen, once we figure out the custom recovery method.

I'm assuming any of the Tengrak GS2 HD recovery images (Odin .tar) will work, as long as you don't flash the associated Tegrak kernel for the ES120L/S/K?

You can always flash the stock firmware above in case you mess up.

 

[markdexter]

Tried the Zergrush method, I had no luck. Oh well no big deal for now

Or flash the first link provided by rxulan in page 1. It's the stock ROM but the system.img has superuser injected in it.

And/or Google for the Tegrak custom recovery in Xda. Just flash one of those recovery.tar meant for the HD, but not the kernel.

ODIN ?

There's no any special procedure other than flash it with Odin
There're many tutorials about it here and there like that for example.

ODIN does not recognise .img or .ext4 files. I understand those are recovery files that CWD can restore but your device should already have been rooted. This is exactly the purpose of this thread, rooting the device first of all. This have been difficult for us to find the right .md5 files to use in ODIN. The device we're trying to root, SGH-i757M.

@ezechias

Odin doesn't recognize the files inside the rooted tar archive (the one linked on page 1), but you can flash them as a tar.md5, which you already know is a preferred format. There are guides online on how to convert it to tar.md5, you can Google it or I can post it later.

First, try to flash the TAR file as is; if it doesn't work then convert to tar.md5, then flash it.

Anyways, it's strange that nobody wants to be the lab rat to test the rooted TAR or the custom recovery that we have already discussed. We have the emergency stock ROM to fall back on if anything goes wrong. Looks like I'll have to purchase this device soon and try it out myself I already have all the files and stock firmware downloaded and ready to go

ICS for E120 K/L/S has been released.
I'm sure the same will happen with I757M pretty soon
