The following files will enable tethering on your I337. Make certain that you use the version applicable to your current build and only use on stock ROM. Use on custom ROM's may cause issues with the ROM. Proceed at your own risk!

Note: This will modify your system causing future ota updates to fail!


Here they are:

I337UCUFNI1_Safestrap_TetherAddOn.zip
(To undo the mod flash the I337_NI1_TetherAddOn_Revert-to-Stock.zip using the same instructions below).

I337UCUFNC1_Safestrap_TetherAddOn.zip

I337UCUFNB1_Safestrap_TetherAddOn.zip


Instructions:
1. Root your device(See Post #2 for rooting options).
2. Install the latest Safestrap.apk.
3. Place the applicable Safestrap_TetherAddOn.zip on ext sdcard.
4. Reboot into Safestrap Recovery and flash the Safestrap_TetherAddOn.zip in Stock Slot (Do Not Wipe Prior to Flashing!)
5. Reboot. Done!

I have an att i337 stock mf3, rooted using towel and su access. unlocked sim using tmo sim, which file should i download? also im on 4.2.2.. or if i update to atleast 4.3 with the newer modem will that fix this problem?

Most custom roms already offer tethering built in. Also they may already have a modified framework-res.apk(which these files replace) and may cause issues. So to answer your question I recommend only using this hack on stock.

I'm surprised that you are one of the few that still has att i337 mf3 phone. if so, stay on it, root it and disable the update. else, you'll lost pretty much everything unless something else happen. however, the only thing i can recommend is that you follow another guide that can do it or use foxfi and the paid key.

:)Holy crap dude! Super cool! If only I didn't have a faulty motherboard everything would be almost perfect, only thing I I'm missing is wifi calling but whatever. I'm gonna have to live without it cause the tmobile roms just don't work for me. Thanks so much man! Hey you think tmobile detects this? I have 3gb free a month.

Reading up on Safestrap now... i didn't think about it until now if I needed it, apparently I've been running without Recovery since I rooted 4.2.2, amateur move!!
I assume this wont wipe anything, just allows me to setup a recovery and flash the tether add on? correct

Pardon the seemingly easy question ( that I haven't found answers to yet)

[alot of updated reading lately since I updated from MF3 4.2.2 and my age old root method]

Correct. Installing safestrap will not wipe anything.

Awesome, installed without issues.

The connection does appear to be quite a bit slower than using the previous theringprovision.apk with 4.2.2.

Would flashing a different modem help this?

I don't believe a new modem will help. And I only briefly tested so other users should chime in as to whether they are also experiencing a slow connection.

Downloading now...

Is it just as simple as flashing over the previous one, or do I have any maintenance to do first?

Flashing it now, I'll get you an update in the morning.

Edit: Seems quite a bit faster after flashing the new file.
I wish I had done a speed test first but the results below are from my second install


36.64Mb down 12.95 up.

Once I rebooted I got the message "Safestrap disabled"
is that ok? I noticed the security policy in the 4.4.2 update with Samsung seems to like the ban hammer with alot of rooted stuff.

I don't know what kind of LTE speeds you normally get in your location but those speeds that you posted are more than decent. And I wouldn't worry about the safestrap disabled message, that's normal. I definitely made a mistake when compiling the first version of the tether add on but this latest version is definitely correct enjoy.
