Root HTC One Rooted (How remove it and update)

cristianocag · Jul 23, 2015

Hi guys, I bought a Htc one from a person, I just rooted (SuperUser), and now I want to update. But, after read foruns, I really don't know how can I proceed with caution.

----
What I know:
Android 4.4.2
System Version: 5.14.531.1
Radio: 4T.27.3218.14

HTC Recovery Mode says that:
*Tampered*
*Unlocked*
S-On
---

I just wanna to back my phone to the original settings and update. I saw at Htc website the Update (T-mobile) (RUU_M7_UL_L50_SENSE60_MR_TMOUS_7.18.531.2_Radio_4T.35.3218.16_10.33Q.1718.01L_release_421697_signed), but i don't know what to do.

Can anyone help me please?? Thank you very much!!!

First things first: that RUU is for a T-Mobile US handset. So is your phone a T-Mobile (US) model? If for example it has a T-Mobile splash screen then it probably is. If not then the definitive way to tell is to set up fastboot on a computer, connect the phone to the computer, boot into the bootloader (reboot while pressing the "volume down" key) and type the command "fastboot getvar all" on the computer. Let us know what the "cidnum" value is, since that will tell us the "customer id", i.e. the original branding of the phone. The RUU will only work if the cid matches, so this information will help identify the RUU you need.

Of course if you already know that it's a T-Mobile handset you can skip all of that

To use the RUU, download it to a Windows PC. Connect the phone to the computer via USB and put it into fastboot mode as described above (you should see "fastboot usb" on your screen. If it doesn't say fastboot at all but fastboot is an option in the menu you see, select that option). Then run the RUU .exe on the PC and just follow the instructions.

You'll need drivers, which you'll get if you install HTC's HTC Sync Manager software (which you can download from their website). But make sure HTC Sync Manager itself is not running, as that's been known to cause conflicts with the RUU.

The RUU will wipe the phone completely, so make sure you have anything of importance to you backed up before starting this.

Thanks for your fast help!

Yes, my phone is a T-Mobile Model, has splash screen, and T-mobile Apps. So, even with root, Can I download the Original File from T-mobile at HTC site and install like you said? I thought that would be more complicates from what I read, like unroot, S-off S-on process, etc...

I will try what you tell me. Thank you!

As @Hadron said, that file is for T-Mobile US, not T-Mobile International. Unless you bought your phone from T-Mobile in the USA, it's probably the wrong file.

Best to do -

fastboot getvar all

And say what the CID is as @Hadron suggested - it's going to save work for you to get a good start.

If it is a US phone, instructions are here -

And prepare as @Hadron said.

Before running the RUU, remember to go to FASTBOOT USB mode and say in a command window where you have fastboot -

fastboot oem lock

The RUU will not work on an unlocked phone.

Just came back and the first thing I thought was "whoops, should have mentioned that the bootloader would need relocking!". But I see you beat me to it

I bought from a man at Canada. I install a Simple CID Getter, that returns "T-MOB010"- TMUS. So, it's US, right?

As I said, at recovery I read: Tampered / Unlocked. At other line, things like S-ON.

So, first thing to do is go to FASTBOOT USB mode, after that go to command window and "fastboot oem lock " . I don't know hot to do it, but I will see at youtube and I come back here!

Thanks @EarlyMon and @Hadron

Hi guys,I will run the setup now. Just another question.. My carrier at Brazil is other, "OI", so Is it possible my SimCard doesn't work more after all? Like I lose the "Sim unlocked" status? Or, no matter what I do, I will not lose the "Sim Unlocked".

Everything is working guys! Thanks a lot!!

Well if your device is the HTC One (M7) then unless you have really old firmware (mid-2013) you can't root it without data loss. Or at any rate you can't do it using anything that I personally would be comfortable recommending (I don't know whether kingroot etc would work, but I wouldn't use something like that if there was any alternative). The best way to root one of these really is to unlock the bootloader (which will wipe the device), install a custom recovery, then use that to back up your ROM and then root it.

If you have a different device, better to ask in that device's section of the forum. Rooting methods do depend on the device.

I agree. I just came here after posting this on a video recommending a custom recovery.

KingRoot did root my phone, but also installed bloatware onto it (I don't have an HTC, but a LG Tribute, LS660). The adware gave absolutely no indication of a link to KingRoot, and I uninstalled numerous other apps before the attempted uninstall of KingRoot gave me definitive proof. The ad-serving charging screen came back, this time admitting the link to KingRoot. It also claimed it would let you disable it, but I had had enough by that point and it was a script from a zip file that installed SuperSU that vanquished KingRoot after a bit of a software tussle.

The opened up memory space has been paying smooth dividends ever since, and the programs battling somehow felt like Arnold Schwarzenegger vs. Robert Patrick (who, by the way, I thought did an admirable job in "The X-Files" even as the show was crumbling around him), but that red light from the mechanical eyeball of KingRoot has finally been extinguished, and now I have a rooted phone.
