Achievement Unlocked! EVO 4G Now Fully Rooted, NAND Protection Defeated, Full Write Permissions To /system. Incredible Next?

Problems Gaining Root On The EVO

If you've been following the EVO 4G root progress, you would know that the current root status is incomplete:

  • the unrevoked method allows granting root to apps but doesn't allow writing to the /system partition, which means you can't remove applications added by Sprint and do any kind of useful hackery, such as installing custom recoveries or ROMs
  • toastcfh's original method (now known as Part 1), which grants write access to /system but only in recovery mode, which means you need to reboot your phone into a special recovery console to gain those write permissions. This method at least allow installing custom ROMs but you still can't write to /system, even when using those.

The /system write protection, which also exists on the Droid Incredible, was a new method of system lockdown implemented by HTC using NAND protection. No other Android phones used this method before, as far as I know, which is why full root was much simpler to achieve on such phones as the Nexus One.

Full EVO Root

However, as of tonight, thanks to the amazing effort of toastcfh, a well respected Android hacker and the creator of the original root method, we now have instructions for achieving full EVO 4G root, including writing to /system from within a running OS!

This means you will be able to remove those pesky Sprint apps and finally use ROM Manager to install recovery images and flash custom ROMs.

The instructions come in 2 parts, the 1st one being the same crippled original root method:

  • Part 1 - same as before
  • Part 2 - new steps that achieve full write access to /system

The root process requires a bit of effort, but works consistently, unlike the current Droid Incredible method, which requires quite a bit of tinkering and luck.

Massive props to toastcfh and the Android development community!

Now get rooting and report back. The comments are waiting for you.

P.S. Is the Incredible next? It uses the same NAND protection, and if the same methods used for the EVO can be applied to it, we may be in luck. We will clarify this when we receive word from developers.

    Trying this out now. Will take a bit of time but this is excellent news!

  • Lewis

    Hmm, what about the Desire?

  • Palak Desai

    Any way to make this into a simpler method... something like unrevoked? Thanks

    • http://www.AndroidPolice.com Artem Russakovskii

      We'll definitely keep you all posted if one surfaces.

  • RickB

    Are chances good or bad that the Unrevoked root will eventually give us full root as well?

  • Cody

    Toast deserves a toast! He's my number one idol! Congratulations to Toast and the other hackers.

  • traian

    like som1 else said; what about the Desire??!

  • donald

    what are the benefits of rooting?

  • HQ

    after rooting can you use any sim on it?

    • http://www.AndroidPolice.com Artem Russakovskii

      EVO and no other Sprint phones have sim cards.

      • Søren Blackgaard

        A blackberry 8830 on sprint has a simcard... some verizon phones do too... but i'm only adding to the confusion.

      • Slim00o

    Worked for me....I think i got root! Part 2 worked perfectly.

  • Weezy

    The process is a bit cumbersome, but definately worth the effort for a much smoother device with much better battery life (for me anyway)

  • agreen

    Does rooting void warranty or insurance? Also am I able to root with the latest updates to the evo? Thank you!!!!

  • JB

    Does this mean since that the evo can be used on verizon now

  • Braggston

    I have a brand new fresh from the store Evo and the Part 1 step will not work. I get a "main version is older! update fail!" error. Help!

  • sh!ft

    How does one unlock the evo and set it to accept a tmobile flex account number. Now that's a tricky hack I've never seen done before

  • andrew

    does rooting it automatically unlock the phone to use on another cdma carrier? or is there another step that needs to be done?

    • http://www.AndroidPolice.com Artem Russakovskii

      Actually, rooting has nothing to do with it. I'm not sure you can unlock it for use on other CDMA networks... Read more about rooting here

      • andrew

        thanks for the response.. i know what rooting is, and i know what unlocking is.. but it seems like everything ive researched about unlocking the evo says unlocking NAND protection, which i dont think is what im looking for..?

        • http://www.androidpolice.com Editorial Staff

          Unlocking NAND basically means getting write permissions to the system partition, so you can remove apps and install custom ROMs, etc.

        • andrew

          yes thats what i read.. and thats what keeps coming up when i search for unlocking for another carrier. im new to android so im trying to get as much in as i can

  • vmnet

    After unlocking or rooting. can the phone be used with boost or a prepaid service?

  • jenny

    Hi... I'm interested in rooting my phone for nothing more than using the wireless hotspot app available on the market. I'm using a tether at the moment. What is the simplest way to go about this...
    For some odd reason I'm just scared of bricking this Evo .. though I'm fine with working on computers. Any suggestions?
    thanks so much
    Jenny

  • vision77

    You could try http://www.unrevoked.com/ to root the EVO. Worked great for me, and now I can use the wireless tether app.

  • Chi Chi Obufor

    i bought an unlocked fully rooted htc evo. But im using at&t, so how can i activate my at&t service on the phone if its unlocked? Any answers?
