SGH-i257 AT&T Guinea Pig for Root ~ - Galaxy S 4 Mini Q&A, Help & Troubleshooting

I have a Galaxy S4 Mini SGH-i257 U.S. AT&T model that I pickup off ebay with a broken touch screen for cheap, I have replaced the screen myself and done a factory restore and it works like brand new. What I'd like to do is offer to try any approach that any interested Dev out there has to try to root this thing, I'm not worried about bricking it or anything else, it can be sacrificed for the greater good as far as I'm concerned. I happen to have this exact same model as my own phone and desperately want to successfully root it, hence my motive!
So how about it? Any Dev's have any ideas to try? I've already tried all the towelroots, motochopper, kingo root, the Chinese one click root, tried the Androind toolkit from skipsoft and all the root tricks for the SGH-i257M (Canadian) models that I can find here on XDA, none have worked, so I am reaching out to any interested dev's with a Guinea Pig to offer up -
Let me know and thanks in advance for any interest.

Rooting my GSIII (T-Mobile) with MacOSX / help

I have my S3 all clean and sexy.
I'm looking for a way to Root my SGH-I999 (correct me if im wrong), and i have a macbook pro. Sorry for mentioning that, i know i should be stoned to death for even mentioning that.
I have seen a few different tutorials on rooting the S3 for windows, and even one or two for MacOSX. But i wanted to be sure that this would work for my T-Mobile variant as well as the international versions that are shown in the video.
Could i use the international version's tutorial?
If not, where could i find a good place to root my device?
Thanks!
You could use boot camp/parallels on your mac for windows, and root your device that way. After rooting, be sure NOT to install ROMs that are not compatible with your device variant; doing so will result in a bricked phone.
Good luck!

[Q] SGH-1257M Rooting Questions

Hey there guys!
New to this site and the world of android modding and just bought myself a new S4 Mini from my cell carrier (FIDO). Im pretty tech savvy when it comes to computers and whatnot but i figured id do some research into it and found this site
Ive been reading on the forums and whatnot about rooting this phone but all i can seem to find are guides on the older GT-I9195 and 9190 moddels.
So i guess what my question is (and forgive me if its been asked a trillion times but im newb) is that is it possible to root this phone ,SGH-1257M, and still retain the same model number and all the features that comes with the phone ? and if so is there a CLEAR guide to doing so, i have cookies ;P (from what ive read it gets put as a GT-I9195 or 9190 and thats not what im looking for).
Im not worried about voiding my KNOX warranty as i have a plan with FIDO that offers replacement phones with no questions asked (water dmg etc) so if need be ill mess up the phone before i replace it.
Ive tried once using this post http://forum.xda-developers.com/showthread.php?t=2470173&page=7 from the guys suggestion at the bottom but once its done i keep getting TONS of KNOX notifications stating something is trying to access the system and its prevented it. Plus when i use root checker it says it has failed.
Im assuming this means try again but im just asking to be sure before i continue to flash my device lol. I have the stock rom for my device downloaded from Sammobile so if need be i can restore it to stock again (ive done that already once using odin) and start over.
Thanks in advance to anyone who helps a fellow modder out
Cheers!

I am complete noob on rooting, flashing, etc. I am hoping that someone will post instructions for SGH-I257M in detail, that a technically competent but noob to this process can follow. As it is now you have to go to a few different places, gather and analyze the procedures, understand as best you can, and take your chances.
If you do this please post your results, in detail.
The SGH-I257M is a Canadian model. I am in London ON. Are you nearby?

Hey man thanks for the reply. I have managed to root the phone successfully using the I9195 Method (For LTE) without flashing the kernel over (and therefore changing the phone model to I9195) and kept my sgh-i257m model number. Pretty sweet!
The only issue im having now is HORRIBLE battery drain occuring (I can literally watch it go down when im using the phone):victory:. I know flashing the I9195 kernel should in theory fix this but im afraid that if I do that ill never be able to get back to the sgh I257m model even if I have the stock rom (they are on sammobile).
If someone can confirm that I can indeed flash back to sgh model then ill gladly loose the features for better batter life! Otherwise I might just stick with an unrooted device for now and see if anything comes up soon
Possibly Figured It OUT!!!!
Ok so after a few days of playing around and reading a TON i think i have successfully figured out how to root the s4 mini SGH-i257m model and still retain that model number.
The steps are quite simple as you just follow the GT-i9195 rooting guide to the letter which can be found here http://forum.xda-developers.com/showthread.php?t=2364980.
After rooting using this method you will indeed trip the KNOX flag so be sure to be aware of that BEFORE you continue.
Once I did that and checked with root checker app i was beyond excited. But pretty much right away I was plagued with battery drain issues from hell (i could watch it drain a % a minute at some points) but i was VERY wary about flashin the GT-i9195 kernel because i still wanted all the features my phone model added (i know im a stickler). But after only using my phone for 5 hrs total (most of it standby time in school) and having only 8 % left i could not deal
So i flashed the gt-i9195 kernel onto my phone, reboot and expected my phone to say gt-i9195 model but its still SGH-i257m!!!
So basically just follow the GT-i9195 root instructions and your good to go as far as i know. Even the battery issues seem to have disapeared
hope this helps out any other Canadian s4 Mini owners out there, as i know this was frustrating for me in the beginning.
If you were to install CyanogenMod 11's latest nightlies, you will still retain the model number thanks to arco68

[Q] Question about root for sm-807t

Hey everyone. Been coming to this site for a good while now and recently just purchased a galaxy tab s 10.5 LTE from T Mobile. I love it. But of course I'd rather do without TouchWiz. Even a root would be so awesome for this model. My question is, is there anything I can do to get chainfire the firmware for this so it could possibly become compatible? I've searched high and low but looks like nothing is available for any of the SM-807 variants. Mine still uses the Exynos processor. Believe it was just Sprint and Verizon with the Snapdragon. Anyone with the 807 variant find anything available or have any idea if a root is anywhere in the near future lol. Just figured I'd ask. Or maybe someone went ahead and used a root for the 800 or 805 variants and it worked, however I'm sure that's highly unlikely. Thank you guys for your time!
Cfautoroot doesnt work on the 807s. Some tryed one and had a sprint tab s and bricked it. They couldn't even restore as there was no firmwares out yet. Any way if someone can pull their recovery (idk how) and send it to beanstown or chainfire then they can port it. We should be getting root for one variantof the 807 soon. I forget which one though.

Gotcha. Thank you for the info. I'm going to see if I can figure out how to pull the img. Hopefully Samsung releases the firmware soon. Appreciate the answer!

[Q] SCH-i435 help.

Ok, I have spent roughly a week searching these forums and the rest of the web for a way to root my verizon S4 mini. I have tried everything, towelroot, kingo, saferoot, all the odin methods listed. Nothing works, everything fails and never achieves root status. I am starting to think that it's impossible, can anyone point me in the direction of a method that is test to work on the most recent kernel for this phone? I am sorry to post a new thread but it's my last resort before giving up. Remember, Ihave a verizon SCH-i435 not one of the GT models, there seems to be tons of information on those models but nothing much for the verizon.

Can't find a rooting method for my tablet

Hi, I have a Samsung galaxy tab 3 from AT&T (SAMSUNG-SM-T217A 4.4.2 KOT49H.T217AUCUBNI2) and I would really love to root my device. I've heard kingo root would work for it but I've had no such luck with both the app and the windows application. If anyone could give me some insight I would be eternally grateful. My goal is to get root, get a custom recovery, and then hopefully flash some custom ROMs to it. Once again I am extremely grateful for any help anyone can give me. Thank you for your time, XDA. Also if it makes any difference its the one you can put a sim card in.

Try give Kingo Root a go. Although you will have no custom recovery or custom ROMs, you will still have root access.
I don't know if this would work or not, but maybe try using the root methods for the SM-T217S. You will see those in the forums, but no mention of the SM-T217A. However, they should be pretty much the same, as far as my knowledge goes, so give it a shot.
