When i started this thread, not many rooting guides/ softwares/ techniques around, nowadays there are tons of it so this guide is kinda obsolete . . .

So this will remains here as a guide & the same can be applies for rooting the unrootable MTK devices & also for the latest unrootable MTK 4.4.2 devices too . . .
Tips : Upload stock recovery.img, port custom recovery, patch SELinux & root it via ported custom recovery


One of my friend bought the latest, cheapest Shanzhai clone of the clone, MT6577, 4 inch S3 9300 android phone & it doesn't come rooted, with 3e recovery & no gapps ! Can't find support at all b'cos there is no brand on it !

Tried all existing rooting doesn't work... So far i've tried zopo zp100 4.0ROOT by008, mkroot, SOC, Root_with_Restore_by_Bin4ry_v3 & a few other more that uses the exploit /data/local/tmp method all fail to work...

With that, it triggers my interest & while looking for solutions at www & xda, found out mostly branded android phone has cwmr & therefore it is the easiest way to gain root access...

And so here is the updated tut that exactly to do that & i believe its universal & it can be use on Any MT6575/ 77...

Happy Modding...

Added on Oct 17, 2012 WARNING : MEDIATEK SMART PHONE FLASH TOOL
i've seen far too many times that fellow xda member make this same mistake over & over again, including myself...

So pls pls people, don't use SP Flash Tool & download ROM not meant for your phone, it will brick it & there is no way to revive it back ! After you have download wrong PRELOADER, your phone will be completely dead, cannot power on, no charging, no recovery, no USB vcom detection & you can say
to it...

Here is the WARNING again :

NEVER DOWNLOAD ROM NOT MEANT FOR YOUR PHONE. IT WILL BRICK IT !

Added on Nov 18, 2012 - Unsecured boot.img rooting

It turns out that this cwmr rooting has mix response...

Thanks to fellow xda friend, jbctiong, he has pointed out that ro.secure=1 is impossible to root on latest MT65xx unless it is change to ro.secure=0 so big credits to him... i have informed this to Master Shifu dsixda & he has added this to the latest Kitchen update...

While on the www, there has been alot of 'unsecured boot.img' & many has brick their device b'cos they thought it was for theirs...

The best way is still to use your own device boot.img...

So here is the Updated Unsecured boot.img rooting * tut * to root the latest 'unrootable' MT6577 & i believe it should work on MT6575 too...

Haha, my bad... my bad...

Credits to liquidini who actually tested it out & reported it back here that makes me aware that there is a bug. i just step on it & confirmed it is already dead, so now the plugins is bugs free...
--------------------------------------
Added on Dec 26, 2012 - WARNING again
i've seen just too many bricks recently by fellow xda member...

So guys, after gaining root access pls pls use this tool to backup your device Factory ROM out of it, if you don't have one...

Credits to Russian Master Shifu rua1 for creating such an awesome multi-tool that can be use for rooting too...
If you can't use the backup function, its b'cos ro.secure=1 you can either use my previous Unsecured boot.img plugins or just reboot to cwmr & do your backup from there...

MTK Droid Root & Tools can created ro.secure=0 boot.img & cwmr too...
--------------------------------------
Added on Dec 30, 2012 - Root via MTK Droid Root & Tools
i really wonder why so many user find it so hard to use this awesome multi-tool so i prepare a tut for it...

As said before, if it still doesn't work, you can actually still root it & backup your device Factory ROM via ported cwmr...

Thumbs up
Thanks so much for the tutorial.

Unfortunately it does not work for my phone, the Hero H2000+ build 120920.

Tried this as well: http://colonelzap.blogspot.de/2012/1...-tutorial.html

You got anything else I can try?

Thanks a lot.

haha, just found out yesterday, in fact actually all ICS rooting does work after all...

i think there is something to do with the recent OS update that it cannot be rooted for all latest MT65xx...

The trick is Wipe data/ factory reset then only run the rooting programs, most of it work after doing that...

AFAIK, ur H2000+ contains the script recovery-from-boot.p at system & install-recovery.sh at system/etc; both of this file are responsible for auto reverting any cwmr back to Stock recovery...

Sorry? So what exactly do I need to do? I'm quite new to all of this. Can I just delete those files from ADB? Can I do a wipe/factory reset then remove those files/edit them?

o i c, first you need to reboot into stock 3e recovery by holding volume +; don't let go & press & hold power button...Try navigating with either of the 4 key button; go to Wipe data/ factory reset, reboot & use any ICS rooting after this should work... make sure USB debugging is switch ON & you'll need to have external memory card too or else it won't work...

You can't delete anything at all without root so it won't work on ADB too until you gain root access...

However, you can install any Root Explorer & see if both of that files exist then after gaining root access, you'll have to rename it to something else & flash cwmr either with SPFT or latest mobileuncle from google play...

--------------------------------
Whoops, just realize that ur H2000+ has only the menu key button...

Then navigate is the volume +/-; Power button is the Enter key...

Thanks for that.

I already flashed CWM as my recovery. Will that work or should I go back to 3e?

And when you say "use any ICS rooting after this should work" do you mean install the root zip file?

Thanks.

Since you have already flash cwmr, can boot into it ? scroll down on mobileuncle tool & u'll see Into Recovery Mode...

it should pop up & ask for root access meaning u stock ROM oredi have root access, then no need to install but you can always update it since it is the latest version...

else then you need to root it with either zopo zp100 4.0ROOT by008 or Root_with_Restore_by_Bin4ry...these two & a few others works after wipe data/ factory reset...

Can you reboot into recovery a few times to check whether it has reverted back to stock 3e recovery...

I can boot into CWMR and install the zips but after I successfully install the zips I go to reboot and CWMR asks me to fix the root then it freezes! I have to take the battery out and back in again.

haha, that means ur stock does have root access... normally, when u install newer root cwmr will ask u to fix it after flashing, don't press any key yet & a new screen will pop-up...

navigate to Yes - fix root & it will solve it...

Thanks.

it shouldn't take more than 1 min but if it still doesn't auto reboot after 5 min then something is definitely very wrong...
