Not necessary as in if you do not do it it will not work. It is optional you can do it if you want to or not up to you.

I don't know why you wouldn't, it can't hurt anything and better safe than sorry, right?

I personally haven't done it, but from what I understand you should be able to on both counts. Back up first, just to be safe.

[Q] Does rooting wipe?

So i have a lot of experience with htc's, and my dad has a Desire HD he wants to root so he can use Ad-Blockers etc... SO i read the sticky, but does it wipe the phone? I don't see it mentioned anywhere... Also can i just keep him on the stock rom, because it mentions flashing a new rom etc. and i don't want to do that.

Apps, yes. App data, no. At least not that I know of.
So i first backup, then the rest wil happen automatically with the toolkit? Or i need to downgrade manually?

AAHK comes with a very clear manual. That should all be covered in it.
According to this post: http://forum.xda-developers.com/showpost.php?p=24601222&postcount=6254 It can be rooted without downgrading or losing everything.... Anyone can confirm this for me? Would try it myself but cannot risk messing up my dads phone..

Is that for SuperOneClick? I believe that only works when you're already S-OFF.

Root Tmobile ???

Now we have US Tmobile T889. Where and how we can root this phone ?
In it's own forum once someone discovers the root and creates the forums.
Patients, it JSUT came out.
Also, I got the white and iPhone owners are jealous. They keep doing side-by-side comparison.

HAHA. I was going to ask the same question.
I didn't realize how big this phone was until I held it in my hands (coming for G-Nex), but the thing that caught me off guard was the sheer speed. This phone is freaking FAST. Had it for couple of hours and I love it!!!!
Now waiting for Root.

did he try using CWM to install it? that's the best way to go about it. since CWM should universally work.

why? both phones have the EXACT same chipset. i'm pretty sure you can flash n7100 stock firmware on t-mobiles and it would work. the reason why previous phones were not inter-flashable was because of the differetn chipset used. both n7100 and t889 use the SAME exynos chip. this should be fun. I'm ging to buy an AT&T and flash the N7100 to get rid of the bloat.
thanks it worked like a charm

I believe you need root to install/use recovery.
Trying to root with the wrong procedure can (and did ) brick a phone. After root, flashing ROMs cannot brick a phone IF you ONLY flash from Recovery. If it doesn't work or even boot up - flash something else or restore backup.

Yes, it would be nice if a tmobile user would confirm the method they used. Want to root so I can get some titanium backups restored.
I can verify that root works with the toolkit on TMOUS SGH-T889. Selecting option 2, then option 4 [works on any build]. 5 minutes later, root and CWM.

they are probably different radios. just because they are the same chipset doesn't mean things will work properly. if they have different radios. which they should. flashing the international will mess up your radio. (baseband, modem, etc)

[Q] Need Help - loosing root

Hi guys
Been a while since I've been on the forum.
I have a Samsung Galaxy S4 - Tmobile and tripped the knox protection.
The issue I'm having is that I keep on loosing root after reboot.
This is the specs of the phone as is:
Model - GT - I9505G
Android 4.4.2
Baseband - M919UVUEMK2
Kernel [email protected] #1
Build KOT49H.08.19.2014
My phone is acting funny (loosing signal, no satelite connection on gps) so I need to root again and install a new rom and kernel. maybe update the modem.
I'm using windows 8.
Please advice where to take it on the next step.
Thank you
Update to the NH7 bootloader. Or at least reflash the stock MK2 firmware and root with CF auto root

You have a i9505G......You need firmware for that device. Not M919........
And what do you mean "loose root"? What method did you root with? I hope it was for the i9505G......

When I checked my phone now, looks like I have M919 Galaxy S4
Not sure, than maybe I've installed the wrong firmware?
Loosing root, meaning that I root the phone, than when I check it after a while is not rooted anymore.

If the firmware showed different on the phone the hardware label model, does it mean that i've installed the wrong one in the past?

I was thinking to go with the other one ))
I fallowed the guide there and installed M919UVUFNH7_M919TMBFNH7_M919UVUFNH7_HOME.tar.md5
Now on start, was thinking to let the phone sit a little bit, but I am getting " Unfortunately, the process android.process.acore has stopped" multiple times. Like a lot of times and I keep on hitting ok.
Any idea why? Is that ok?
Should I just move on np?

Go into recovery and select factory reset. Reboot.

Software Update

anyone else get the prompt to update the software? are you going to update?
Got it and did it 2 days ago
Same and same
probably too early to know, does anyone know if this update will affect root? coming from htc, i remember updates were frowned upon as they can make rooting more difficult.
