[Guide] How to Root / Overclock T-mobile Official 3.6.390 Rom

Here is a simple step by step guide to rooting / overclocking your updated Defy. If you are like me you upgraded to the new OTA (over the air) firmware only to lose your root access / overclock
As with any free advice given out on XDA, if your phone gets borked and / or something goes wrong while you are trying to root / overclock, I do not work for Motorola and I take no responsibility for your $500 brick.
ROOTING PROCESS STEP BY STEP
1. Download and install the Motorola Mobile Phone USB Drivers (for Windows®)
http://www.motorola.com/consumers/v/index.jsp?vgnextoid=bda09ec8009a0210VgnVCM1000008806b00aRCRD
2. Download and Unzip SuperOneClickRoot (thanks to SteveChou)
http://forum.xda-developers.com/attachment.php?attachmentid=489694&d=1295035181
3. Make sure have usb debugging checked on your phone (menu - settings - applications - development - check usb debugging)
4. Plug your phone into your PC and put your phone's USB connection into "Portal and tools" mode. (After youplug your phone in, pull down the notification bar, click on USB connection then toggle Portal and tools.) and close any Motorola Portal Windows that pop up.
5a. XP USERS ONLY:
Make sure you are logged in with an administrator level user account and run the SuperOneClick.exe file that you extracted in step 2. Then Click Root (The whole process takes less than a minute.)
5b. VISTA/7 USERS ONLY:
Right click on the SuperOneClick.exe that you extracted earlier and click Run as Administrator. Then Click Root (The whole process takes less than a minute.)
OVERCLOCKING PROCESS (These are the setting I have been using for a few days with no lockups / force closes YMMV):
1. Go to Market on your phone and download SetVsel
2. Run SetVsel and input the following settings:
28 [email protected] MHZ
44 [email protected] MHZ
58 VSEL3 @1100 MHZ
Check Apply @ Boot Toggle
3. Click Apply+Quit
That's All Folks!

I tried milestone for a few days, but I've noticed better battery life with SetVsel. I was barely making it through the day (7am - 8pm) with Milestone, Setvsel seems to get me through the night. Then again, who knows maybe I was just using it more that week.

cheers dude think you maybe right looking at your settings the voltages are lower than the defults set by milestone think ill give it a go see how i get on

Thanks. The other two as I understand are like this: First one at 300 is for when the screen is off. It runs the lowest possible to conserve everything. The second one is when the screen is on, so the phone can do what it has to without lagging. The third one is the max the phone can run, so you can run whatever you want, and not worry about slowness or lagging as it will use what it needs up to the max setting. People I see do what you did and just overclock the max to get the full potential out of the chip. The ones that change the first two either want even better battery life, or a little more power midrange when the phone is just on doing its normal stuff. Me, I am using inteks settings on the first page in the screen shot, 300 @30, 700 @54, 1200 @70. Super smooth with heavy load. Scored 1218 on Quadrant. Very stable and I'm happy.

AWSOME
Did the rooting super fast got it under 20 sec lol but just installed SetVsel and app is force closing on me
Edit: Nevermind just rebooted the phone now its working very fast rooting and overclocking

Does rooting the phone this way require the 3G fix after root?

3g fix? ??? I havent had any problems since rooting and 3g is working like charm just like when i opened it brand new

temp root + overclock
is it possible? use the temporary root option and then use it to overclock to 1ghz?
so that i can still unroot it in the future...

temporary root did nothing for me, had to use permanent root option
and u can stil unroot even if u use permanent option

which is better?
is this better than z4root? over 3.6.360 version?!
does it resets the phone or clear anything up after rooting?!
would you still be able to use tmobile's apps and features? like updates OTA in the future?!
thanks!

@lucid i have the same firmware version as you and it rooted fast and also dint erase anything from the phone left it as it is now from the ota updates i believe there not affected
Sent from my MB525 using XDA App

which one did you use? or would you say better? z4root or the superOneClick?
SuperOneClick v1.6.5 is the latest with "unroot" option right?!

I used superoneclick for 2.1 it says but I also have the new version that has the unroot option but havent tried it and z4root ive read that still doesnt work with the new firmware update
Sent from my MB525 using XDA App

rooted!
ok now i rooted my phone and it said SUCCESS in the end, that means it went OK right?
after this should i use milestone ot setvsel or setcpu? which one would you guys prefer?
i'm trying setvsel now nut it doest show me:
VSEL1
VSEL2
VSEL3
just the round lightning with slider bar and the rest of the messages
can i also uncheck the USB debugging now?
thanks!

Cool now your rooted the setvsel thing happend to me also just unistall and reinstall and that should fix it if not turn off phone and turn on again as i did and yes you can disable the debugging mode without problems

hi again, how do you get the vsel set to 65 for 1.3ghz
all i'm getting aside from lower values of 800mhz are:
1000mhz, 74vsel
1200mhz, 80vsel
1200mhz, 80vsel (custom)
does vsel means the higher the value the more power it consumes compare to
yours set to 65?
oh btw, if i factory reset this, is it still rooted and overclocked?

The lower vsel value the less baterry ir uses bit might cause stabability issues and id you factory reset it stays rooted but overclocked i cant say cause the app is what controls the overclocking so i would guess it goes to factory clock

Voltage control questions

I finally got srf 1.2 to work really good. I have a few questions about voltage control.
1. Is it safe to overclock and undervolt?
2. What advantages will I see from undervolting, longer battery life?
3. Does overclocking really make that much difference, and is it safe?
4. Is there a how to, or a guide that can show me how to do it?
Thanks

Yes its safe just don't use the set on boot feature. As for battery improvement some people notice a difference and others don't I personally do undervolt. As for the guide just mess around with it for a while everyone Has different Preferences so results will always be different. I don't undervolt below 75 cause when I do I get lock ups. If you lock up just pull the battery and you'll be fine. I also recommend to use journaling ON cause if you lock up and pull the battery with journaling off you might get data corruption.
Hope this helps.

What kernel are you on?
I'm on Twilight and can overclock to 1.3ghz with full stability. I don't undervolt. Combination of my phone doesn't like it and I'm not looking to save that little battery to get wakelocks (phone doesn't come out of sleep mode because the processor speed is too slow or doesn't have enough juice to make that push.)
If you're using a kernel that can go to 1.4 or 1.5 test it for a while before you save your settings. Also consider buying the paid version. It allows over volting which may allow you to supply enough power if 1.4 or 1.5 causes freezes.
The app is pretty basic. The top bar on the first screen is how low you allow the processor to go in speed. The bottom is how fast. Lower than 100 mhz causes wakelock for me. Or used to. Haven't tried since. My settings are 200-1300 mhz. Second page is voltages. They start at default. If you have extreme, moving them to the right will overvolt and give those speeds extra power. Moving the slider to the left undervolts. Some people can only undervolt at the lowest speeds of say 100-400 mhz. It's a lot of trial and error. Have fun though!

So on the main page my settings are 200-1300, then I press apply settings. How can I tell If it is working, it does not seem that much faster? Do I have to set this every time I turn my phone on? Do I want to save thos for boot up?

When you turn your phone off then on, does it show those same settings? The speed boost will be slight. It's not like we're resurrecting Jesus here.

[Q] Calk's Preset Profiles to save battery question?

Notes about Battery Saver script
Can be used with kernels that have init.d support
It completely eliminates the need for an application to set CPU speeds or profiles
Easily customizable if you use a text editor(scripts located in /system/etc/init.d)
It will set Max CPU speed to 500MHz & Min CPU speed to 200MHz when a sleep
If SetCPU, Overclock Widget, Android Overclock or QuickClock Advanced Overclock are detected, the script is ignored, so it will not affect them
Preset profiles are:
1.2GHz - 100-85%
1.0GHz - 84-36%
800MHz - 35-0%
And just an FYI, even at 800MHz, the phone still operates very well & smooth but the battery saving are the real benefit
Click to expand...
Click to collapse
Does this mean that if I don't use Set CPU or any app that undervolt it, the phone will AUTOMATICALLY drop the CPU speed according to my battery level:
1.2GHz - 100-85%
1.0GHz - 84-36%
800MHz - 35-0%
Another word, it will automatically drop CPU speed to 800 MHZ when my battery level is 35-0% in order to save battery?

It won't "Drop" the CPU speed, it will lower the Maximum speed the CPU is allowed to ramp up to.

So if I am not doing CPU intensive stuff and just play simple games, email, web surfing phone call, then I am not going to see battery improvement since my CPU probably don't ramp past 800MHZ anyway when I am just doing simple stuff.?

Calk's ROM undervolts the CPU at all speeds so that in itself should help a little with battery life. But you are correct, if you are not doing CPU intensive tasks the CPU probably isn't spending much time at the higher speeds.
There is an app called CPUSpy which shows how much time the CPU has spent in each frequency state.

Your phone will ramp up to 1200 mhz more than you think. When it loads a webpage, it will ramp up to 1200, when it's loading your "simple" game, it will max out for a bit, etc.
It might not stay there for very long, but still. The nice thing about Calkuins rom is that even at 800 mhz, the phone is super smooth and lag free. In fact I just turn setcpu down to 800 all the time.

Let me research setcpu and play around with it. Thanks again for the quick answers.

The way Calkulin's rom scripts are setup, setcpu gets reset on every reboot, even if you have it set to boot settings. The scripts installed will still take priority and the old rules apply, just to let you know. So you would have to set setcpu every boot for it to work, that or remove the scripts.

Team era... Does the same idea apply to the blazer 2.0 battery saving script? or does tegrak break it?
Sent from my SPH-D710 using xda premium

I havnt opened that rom, but Im gonna say the same applies, I remove those scripts, 2 will affect the cpu state.
edit, let me clarify, the scripts take prority, even if the app makes a script for init.d, the original script will take over on a reboot. So the script breaks tegrak, setcpu, and voltage control unless you set the app on every reboot.

I am running Calks 2 and desperado kernel. I notice when using setcpu, if you have it set on boot, it will override calks script.
His script does work well on saving battery life though. I ran oc'd while at 20% and still had 1700mhz blazing on performance gov.
I'd still use Calks script over setcpu or tegrak only due to the fact im too sporatic with my phone use to create optimal profiles to fit the way and when i need to use the device.

Actually in my own testing setcpu will not override the scripts, the slider may stay the same, but trust me, it goes back to 800 (or 1200 over 86%batt), Ive tested it several times. If you want proof Ill tell you how to figure it out. I know Im not respected yet, but I am someone that is known under another name that is highly respected, so, take it as you will.
Sent from my SPH-D710 using xda premium

Era, what's your suggestion for keeping the battery saving scripts running and getting a 1500 ish over clock when needed... something that can do both without having to physically change setcpu everytime. I basically want to permanently over clock to 1.5 and still save as much battery as possible when i have the screen off or it is charging. Idk if setcpu profiles work on this phone because i know they did not work correctly on the galaxy s. And one final question... what voltages do u run at what speeds on the "desperado" kernel to undervolt efficiently?

ERA. I wasn't looking to say that you were wrong in any way shape or form. I would be interested to know how you seen this as I am still in the beginning phases of learning the android system. I do plan on writing my own kernal/roms but I was actually sharing what my logical thought process would have been given the apps and system info I had avail.
I have a little ways to go in understanding the structure and FS of droid. Time is everyones enemy. Thanks for the correction again!

I'm currently running Calkulin's rom v2.5, and even at 41% battery I notice the cpu still hits 1.2 Ghz. Is his script activated by default or am I overlooking something? I also have nothing like setcpu installed.

First time undervolting

Ok so im getting 12 hours tops running blazer 3.7 rom with the el29 1.4.0 gunslinger kernel and ek02 baseband
I have set cpu all I have done so far is just make the profiles. I need some help its my first time trying the undervolting I want that 16 hour plus battery life
Sent from my HTC Glacier using XDA App

Why not just try -25mV for each frequency that you're using? Test it for a few days. Then try -50mV, repeat test, and compare performance differences.
If you're overclocking, undervolting can freeze or boot loop your device

Switch over to Rogue Stock EL29 and undervolt + underclock using Tegrak. I guarantee you'll get 16+. Right now I'm getting 24+ hours with these settings:
CPU Scaling: 200-800Mhz
Internal Voltage: -75mV from default.
Core Voltage: -75mV from default.
GPU Level 0 Frequency: 200Mhz
GPU Level 0 Voltage: 850mV
GPU Level 1 Frequency: 100Mhz
GPU Level 1 Voltage: 750mV
Tweaks: cfq changed to noop
System will constantly reboot if you use Tegrak with Gunslinger so don't do it. Just get Rogue Stock EL29.

Can you list your CPU scaling at each level? Thanks

Make your self an overclock profile and copy paste this into it in through a text editor:
level=5
frequency=1200000,1000000,800000,500000,200000

scaling_governor=ondemand
scaling_min_freq=200000
scaling_max_freq=800000

If you don't know where to find your overclock profiles, go to where your applications install, such as sdcard, the directory will be sdcard/Tegrak/overclock/ then the file will be <profile name>.oc
Use something like file expert to open it as a text, then simply copy paste.

i noticed it said TEGRAK in that field...so this wouldnt work on gunslinger and setcpu? just wondering...cause im looking into this aswell

I'm not entirely sure if it would work with setcpu. I don't know what kind of data it uses.
This is for Tegrak only, as far as I know.
Tegrak will not work on Gunslinger, I use it on Rogue Stock EL29.
This profile for Tegrak delivers excellent battery life while still remaining smooth and stable. As long as you don't murder your phones battery life with applications and data you should get 24 hours + with moderate use.

Yes, simply copy and paste, just tested it out to confirm it will work. Once you copy- paste the data you need to reapply the profile in Tegrak. In order for the profile to apply every start up you will need the full version of Tegrak.

If you're using SetCPU, you have all the tools you need. I recommend UVing -50mV at each frequency 1200 & lower. Click apply, then use your phone. If it works well enough, don't be afraid to check the "Set on Boot" boxes

appreciate your reply, may be a dumb noob statement but...
it will not let me enter "-50mV" or "-" for that matter just "50mV' and isnt 50mV way too low to be stable? i tried just "25mV" and phone froze so.... please help...
Thanks so much.
PS. it will not let me add special characters... just numbers. numbers go all the way down to "0" but not negative numbers....

If you are running calk's 2.8.1, you are already undervolted by 50mV, so no need to mess with set cpu voltages. You can however mess with the underclock settings. I for example run at 800Mhz with the conservative governor and get great battery life. However if you must mess with the undervolting in set cpu, -50Mv means 50Mv less than default. So lets say ur voltage is 1025 at 800Mhz, to undervolt it by -50 you would change it to 975 (1025-50=975). HOWEVER, as I have mentioned already, you are already undervolted -50 by default when on CALKS rom.
EDIT: To prove that you are already undervolted, here are the STOCK voltages,
1704=1500
1600=1450
1504=1400
1400=1350
1200=1275
1000=1175
800=1075
500=975
200=950
Go into setspu and you will notice your values are all 50 less than the ones listed above.

Go into setspu and you will notice your values are all 50 less than the ones listed above.

Thanks for that, I needed to be schooled. So if i'm running at 800mhz all day, why is my battery being depleted so quickly? (I get a good 12hrs per charge)
What's the lowest I can go? (stable)

The lowest that is recommended (atleast by Calk) is -100 so 100 less for each of all the values I listed above. However, if -100 makes ur phone slow or restart, try -75, etc...
Battery all depends on your usage. There are a few things you can try to improve it even more. First of all, flash rogue's newest kernel found here:

Second, make sure to calibrate your battery. The easiest way is to download the Battery Calibration app from the market and follow the directions in the app (its fairly simple). Finally, make sure your governor in setcpu is set to conservative.
EDIT: Also, make sure you manage your running applications. I like to use the stock manager widget that comes with the phone. Allows you to close apps you are not currently using. And finally, you can try running the script found here:
http://forum.xda-developers.com/showthread.php?t=991276
It changes the way your phone uses resources to make it more efficient so it MIGHT also help battery life.
EDIT2: FINALLY, I know you said you're running at 800Mhz all day, but make sure you have your max set at 800 and min at 200. (you never mentioned you were underclocked before so just want you to make sure you are).

If you are running calk's 2.8.1, you are already undervolted by 50mV, so no need to mess with set cpu voltages. You can however mess with the underclock settings. I for example run at 800Mhz with the conservative governor and get great battery life. However if you must mess with the undervolting in set cpu, -50Mv means 50Mv less than default. So lets say ur voltage is 1025 at 800Mhz, to undervolt it by -50 you would change it to 975 (1025-50=975). HOWEVER, as I have mentioned already, you are already undervolted -50 by default when on CALKS rom.
EDIT: To prove that you are already undervolted, here are the STOCK voltages,
1704=1500
1600=1450
1504=1400
1400=1350
1200=1275
1000=1175
800=1075
500=975
200=950

Hey meatwadath, I am running calk's 2.8.1 and went to verify, via setcpu, that I was already undervolted by -50. However, my voltages read the same as what you referenced above. Any ideas?

Means that you are running on stock voltages. That's strange as you should be at -50 by default. Either change the values manually in setcpu, or flash the zip located here:
http://forum.xda-developers.com/attachment.php?attachmentid=845028&d=1325871602
It is Calk's -50 undervolt script.

Thanks bro, appreciate the help. Gave you a few thanks for it...

No problem. Any time.

Ok, where is the settings to undervolt in setCPU, because I looked everywhere in the program and cannot find it. I'm probably just retarded... I'm on UnNamed, Rogue Stock EL29 kernel.

Setcpu- Third button from the top says voltage, then click on the different voltages listed below Apply, pull the little bar to the left to undervolt...

Ok, I don't have that button, only got "Main, Profiles, Advanced, Info, About"
I think it's because I'm on a stock kernel; looked it up and undervolting on setCPU only runs on certain kernels apparently. Not sure though.

Thats probably it. WTH are you doin on stock?!? Get on gunslinger right now!

I concur

Set CPU
For some reason setcpu isn't really helping out my battery life. When I use it I get the same results as if I wasn't using it.

You're probably expecting too much. Its not gonna make your battery last for 2 days without a charge. It has to help if you are using it correctly.
There is just no way around it. Lower clockspeeds=less battery drain.

ditto. I'm on blazerROM v3.7. I think its using the stock kernel as well. I didn't have an undervolt tab. I did set up profiles similar to calks script:
100% - 85: 1200/200
84% - 35: 1000/200
34% and lower: 800/200
screen off: 800/200
The question is, do I need to undervolt? Or could I still be getting the same results if i'm on the stock kernel with this profile set up? I just set this up last night.

I was in the same boat... had Calk's v2.8.1 ROM with stock kernel... updated kernel to Gunslingers.. we will see how it goes... Noob myself, I thought Calk's ROM would take care of everything....
This leads me to think what else am I missing?? Anything I need to do/install/tweak??...
Calk's v2.8.1 with Gunslinger 1.4.1.
Thanks much!!
