CF-Auto-Root for SM-G900T (T-Mobile US)

idtheftvictim · Apr 11, 2014

@Chainfire has released his CF-Auto-Root for the SM-G900T (T-Mobile US) Galaxy S 5.

I take no credit whatsoever for this, just posting a link to his main thread for all to see.

Please go and thank Chainfire!

With this root accomplished, we can confirm that the T-Mobile bootloader is UNLOCKED.

ROMS/Kernels/Recovery will soon follow from our awesome devs here on XDA.

THIS WILL TRIP KNOX COUNTER TO 0x1

ODIN Instructions - Copied from Main CF thread

Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!

- Download and unzip the CF-Auto-Root-....zip file (see posts below this one)
- If you end up with a recovery.img and cache.img file, you've extracted twice. You need to end up with a .tar.md5 file - don't extract that one
- (USB) Disconnect your phone from your computer
- Start Odin3-vX.X.exe
- Click the PDA button, and select CF-Auto-Root-....tar.md5
- Put your phone in download mode (turn off phone, then hold VolDown+Home+Power to boot - if it asks you to press a button to continue, press the listed button, or run adb reboot download command)
- (USB) Connect the phone to your computer
- Make sure Repartition is NOT checked
- Click the Start button
- Wait for Android to boot
- Done (if it took you more than 30 seconds, you need practise!)

NOTE: Sometimes the device does *not* boot into recovery mode and root your device. Just do the entire procedure again if this happens. If it still will not install root and such, make sure that in Odin "Auto Reboot" is not checked. Then after flashing, pull the battery, and boot with VolUp+Home+Power button to boot into recovery manually. This will start the install process.

New to Samsung? Unfamiliar with Odin? Think all the above is a hassle? Get used to it. It's very simple, and us Samsung folk use Odin (or Mobile ODIN ) for everything! It's so very very convenient once you get used to it. Notice the 30 second comment above? For experienced users, the entire process indeed takes only 30 seconds!

Other models

CF-Auto-Root is not yet available for all models - one stock firmwares for these models become available, let me know, and I'll make the corresponding CF-Auto-Roots.

Good stuff, downloaded the zip, just waiting for my device to get here....we have to run the update the Kies first, right? Also, any word about CWM or TWRP? They've already made recoveries for the international versions.

You can run the auto-root on both the updated version from kies, or straight outta the box.

I am trying to get in touch with the developers about TWRP and CWM, but I am sure they are busy trying to get all variants working.

I wouldn't Odin the international TWRP or CWM though. I would wait for a version for us.

For sure, I don't want to brick the damn thing. Luckily I've been here before!

I wouldn't count on it. at least the Triangle away...Knox still hasn't been figured out for previous devices on how to reset it, so I wouldn't count on it for this device. As for getting root without tripping knox, Maybe kingo will update, or root-de-la-vega....who knows at this point.

There basically won't be a way of resetting Knox.
Because of it being more a hardware flag, once it is tripped it is not reversible.
There might eventually be a way to do it without tripping it, but I wouldn't expect that for a while.

Got my S5 and ran the CFAuto worked like a champ... Rooted in 30 seconds.. Yes it tripped Knox but I really don't care.

Since we have root, does that mean 100% that we can flash recoveries and ROMS? Both TW and AOSP?

zaventh · Apr 11, 2014

Worked perfectly.

Yes, though root has nothing to do with this. The bootloader is unlocked, which is why root was obtainable via Chainfire's custom recovery. We have no restrictions on flashing custom ROMs/kernels/recoveries/etc.

I may start working on a custom TW kernel myself once Samsung uploads the source...

Wait, CF custom recovery has nothing to do with root? I thought that was the point of CF "autoroot", am I missing something?

Tmo warranty

Hi,
I'm debating if I should upgrade to SGS5, now that we can root the phone.
Does anyone knows for sure that a tripped Knox means no warranty with T-mo? I'm under the Jump plan and the idea is that I will be able to have warranty on the device if something happens to it (and I do have some apps that must use root...)

Thanks,
Gil.

Are we 100% certain that the bootloader is indeed unlocked. I know that chainfire stated this (although he currently doesnt own the s5).

I just came from HTC, and it states when you boot whether the bootloader is locked or unlocked. Im assuming there is no simple way of knowing whether the bootloader is locked or unlocked like the HTC devices

marriux2 · Apr 11, 2014

Phew glad to see the bootloader is not locked. Gonna root as soon as I get my replacement S5. Can't wait for the custom ROMs

There are reliable sources saying yes it is unlocked and there are reliable sources saying no it still hasn't been confirmed until someone successfully flashes a custom rom/kernel/recovery.

The consensus around here seems to be that it is unlocked but its just people repeating the words of the original few that debated it. And of course since we all want it to be unlocked, it is easier to believe that it is.

I personally don't want to jump to conclusion so i want there to be more discussion on the matter. Therefore i requested the "boot loader un/locked" thread to be reopened in Q/A.

i want to walk down to the store and buy one right now but until its confirmed im waiting it out. $650 bet!
