(TOOL) Perma-Temp Root with *R/W* & Stable!

Thanks goes to #TeamWin for Temp Root
This is For Windows only, if you wish to make it work for linux or mac help your self...
Remember, This is still a Temp Root & any Changes made will be Rest back to stock on a Reboot
It's stable & works 100%
I Personally have not lost Root with this new Method
Q. I thought RW was Fixed?
A. Caused by Deleting an apk / file that was already deleted. Journaling shows it still there!
Keep Track of what you delete, as trying to delete something off system that you alread di hangs the /system into RO state.
Before Using!!​HTC Sync Must be Turned OFF
Put the Phone into Charge Mode only ( Not Disk Drive )
USB Debugging Must be Turned on
What's Fixed:
Revamped due to new Method:
~ Superuser Apps now Function
~ If you Lose Root, all you have to do is Open terminal & type SU then type fixit! > No More Rebooting & running the exploit again for R/W on system to get Root back in place
~ Fixed R/O Bug!!
~ R/W is now Forced
~ /system is fully editable now! until reboot that is.
~ Busybox is installed to /vendor/bin
~ hex Edited libext4
~ hex edited libfuse.so
~~ This is the Last Update due to it working & Stable ~~

Q. Is this permanent?
A. no, it's a temp root method..
Q. Will I lose SU Access at some point while running the OS?
A. You might, but open terminal & type fixit to get root back!.
Q. What about apps that need a reboot to use superuser?
A. Use Fast Reboot form the market for app that need a reboot..
Q. Can I push & remove items to system & will it work?
A. Yes, but all changes are reset on a reboot.​
Once Downloaded, Unzip & double click on the Run_ME_fre3vo_Root.bat File & Enjoy long lasting Root!
OLD NEWS:
Everyone knows that currently with any temp root, you still lose links to the SU Binary & Busybox links, it's just a matter of time before it happens!!
So after digging around somewhat I found an over sight that HTC might use later for system updates via /vendor/bin, who knows at this point though... Anyways, after amount of time the SU Binary along with busybox links if be in system/bin or /system/xbin gets deleted / removed..
Now, what I did was enable the $Path to /vendor/bin which is in the Sensation export PATH..
Any Calls made from this point either be SU or Busybox don't get deleted nor touched from any App requesting the SU Binary!! I've tested this with alot of apps & the Root sticks in place..
Other than Reboot, it might as well be a Perma-Temp-Root!!

I am Asia Sensation..Can i use it?

thanks loads
will give feedback
seems to work the same as before, cant wait until we can permanently change /system files

Thanks a lot !!!
I think the new thread it's beter, for the noob not confusion
with the old one

Great update. You should seriously consider talking with agrabren since your making temp root so much better. And I'm assuming you still can't permanently delete system apps right? Just permanently delete them for the time being until a reboot right?

does this still remove the bloatware as per the previous release? looking at the .bat doesn't seem to remove the apks in the manner/or at all?

Fantastic. Works great.

Even though Root Explorer is granted SuperUser, I still can not modify system files. I also can not actually overclock with SetCPU 2.2.4. It will show the max as 1728000 but it will never scale above 1188000
The process is extremely easy and very user friendly though

i have been trying root my sensation it says its a success but my phone is not rooted can anyone help
i did root it before and it worked i restarted my phone and lost root access as expected but now when reattempt it fails

Reboot did allow me to rename system apps, thank you. SetCPU still doesn't work correctly, but reading the other threads, this seems to be the normal behavior at this time. Awesome tool Eugene.

it doesn't get any easier then this thx for this , everything works perfect except SETCPU is not letting me overclock ...

I really hate to add to the chaos, but no matter what I do. I am not able to get this to work properly. I have HTC sync turned off, and debugging and mock locations checked off, but when it gets to waiting for device, it just hangs, and never picks up the device again. I tried to remove the wait for device commands out of the .bat file, and it gets through but when I attempt to use even titanium, it says root not achieved, and will not let me through. Yes superuser is installed.

EDIT: I finally got it to work. The last two downloads of the files must have been bad or whatnot. I redownloaded a third time and it was the charm! Disregard this. Love your work Eugene!

[Q] Setting liveoc values on boot.

Hi i was wondering if what is the proper way to use an init.d file. I want to set my liveoc value to 105 on boot using an init.d file. I edited the line below in an init.d file using a file manager with root rights.
echo 105 > /sys/class/misc/liveoc/oc_value
but somehow it does not work. do i need special permissions for this??

There's an app called "Script Manager" that lets you create scripts and have them executed at boot

I just learned all this.. so here's my take.
You simply put your script to the /init.d subfolder in /system/etc
There's one more essential step, you'll see all the scripts named with "01, 02" etc. I named mine as "58liveoc" as another post in Dec section recommended. Keeps it out of the way of system scripts and tweak scripts for kernel.
make sure you have " #!/system/bin/sh" at the top and have voltages and Max frequently set before echo for live_oc
see live oc thread for some demo scripts, backup your device!!!!

Almost forgot match permissions of file to that of existing ones... should be rwxr-x--- also change owner to 0 root and group 2000 shell.... did it all using root explorer

OK.. Im sure we can figure it out here
So step 1 you're using a kernel that supports live oc
Step 2 script has been copied from SD to init.d and then permissions and group set(not sure if those stick when copy/pasting)
Step three I guess is renaming it
And step 4 is the script itself...
Are you using one of the preset scripts?
If not.. what values? Voltage/Max/min/oc/gov's
When I screwed mine up my phone would crash left and right
..
Hmm... oh make sure "run on boot" is unchecked in SM for said script... reboot and CPU frequency. Should all be set as desired....
Lemme know? I'm not an expert but if you've got the time Im happy to help

does anyone know if you need round numbers for this to work?
or will something like 113 be such an odd multiplier that it breaks

I think its best to use multiples of 5. That being said I think its capped at 125. Also it requires higher voltages the higher you set it. If you want a 200 MHz bus you can use trinity kernel its compiled at 200 and keeps lowest possible voltages while giving overclock aswell

wait hang on...
I always thought it was a double pumped bus, so 100 base close = 200 bus, the trinity kernel's not actually 2x faster bus than anything else, is it?

ok i have done step 1-3 correctly. about the script i am using the one that is written for my phone, i just changed the liveoc value. is it a must to include all the steps?? can i just set the oc values and not set the stuff i don't want to change?? because currently i have only that line included in the script. i also have a test script inside init.d which does not execute as well which makes me believe that the scripts in init.d aren't being run on boot.

[Q] LG Optimus T P509 (Tmo)

Hello All,
I have looked on every forum I can think of for the past two days and can not find an answer to my problem anywhere... so if i am double posting i am very sry please point me in the right direction...
I successfully rooted my gf's optimus t yesterday using Z4root (extremely easy!!) My problem occurs when i try to flash the recovery thunderg.... I have tried many many times using a Terminal Emulator from the market and then (after much headache) I taught myself how to use adb shell. With both applications and after all my attempts I get the error message: cannot create /system/bin/flash_image: read-only file system. I have followed all the steps as carefully as I can from: All In One Recovery from Android Forums.
Here is the code I followed:
$ su
# mount -o remount,rw -t yaffs2 (your device /system path) /system
# cat /sdcard/flash_image > /system/bin/flash_image
# chmod 755 /system/bin/flash_image
# mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
# flash_image recovery /sdcard/(your device recovery.img name)
# sync
I get the error after I enter: # cat /sdcard/flash_image > /system/bin/flash_image
Any help would be much appreciated thanks!

Why not just use ROM Manager to flash recovery?

I have used ROM Manager in the past to flash but I thought I remembered reading somewhere that the LG p509 was having issues with clockworkmod??
btw thanks for the quick reply!

rom manager can randomly cause problems, so id stick with this first.
what is the error that you get? check the following:
is the file "flash_image" located in the root of your sdcard? and make sure that the name of the file is "flash_image." if that is not the name of the file, replace "flash_image" in the command with whatever the file name is

You're receiving that error because you didn't copy flash_image to your sdcard.

I went ahead and used Rom Manager (figured what the hell) and it worked great! Thanks to everyone for your help!
Now that I have flashed Mik's CM7 I tried flashing francos 19.4 kernel to overclock. Everytime I would set the over clock over 748 the phone would freeze, a white screen would appear, and the phone would reboot.... any suggestions??

That's classic kernel panic. Lower your overclock and try again. Keep lowering until it's stable.

That what I read but I was hoping there was another option... I was looking forward to pushing this little beast a little haha

Go to 729,710...729 is recommended but some users claim to get as high as 806, I've never used higher that 787, what your experiencing is called a KP (kernel panic)...try changing your governor around than OC at higher than 710 and see what your phone is doing...or try to start over from scratch...wipe it all than reflash rom than OC....just a heads up I run 480/729-767 on interactivex (governor) and noop for I/O scheduler..follow my configuration and see what it does for you

It's luck of the draw. Some can do 768 or better while others struggle at 729.
For example, mine is stable at 748 but panics at 768.
Trust me, your phone is a whole lot better now than when you bought it

Oh no question about it!! Its running sooo much smoother. The Optimus is actually my gf's phone. I put CM7 on it because I running it on my HTC Sensation and its awesome!

You can only push this device so far before you fry it, settle for adequate performance and stellar battery life....I'm not even sure why there's an option for us to OC past 787, our phones don't have a snapdragon processor....some roms can handle OC at higher voltages and some can't, most I got out of cm7 is 787 but its not stable enough for me
Sent from my LG-P500 using xda premium

Thanks man Ill take your word for it! Any other suggestions/concerns with the phone?? I just flashed the rom yesterday so i dont know what to expect (as far as bugs and such) are there any nightlies yet?

Well if you have a computer, learn how to code source and you can cook roms for everyone else to enjoy....there is alot more to android development other than the basics...ie...root than custom recovery and custom roms....speaking of kernel panics, I just had one at 748 on popdogs oxygen port, cm7 I can easily run 767...btw are you using no frills or setcpu

Actually, CPU's rarely fail due to OC'ing. Instability forces you to lower the clock. The phone's metal casing and battery acts as a heatsink.
Batteries on the other hand are extremely susceptible to damage due to excessive heat. This is what you need to watch.

Is the stuff hard to learn? I'm not bad with a computer but to be honest it took me like two hrs to figure out how to adb shell haha... i believe im using setcpu with the interactiveX governor but i dont have the phone right in front of me so im not sure..

Read the sticky in the Dev section. Links to all the tutorials are there. Read them and see if it's beyond your skill set.

Didnt know that either thanks! Ill definitely keep that in mind for my Sensation shes tends to get a little warm. I have it OC at 1.56 which isnt that high but it still gets warm.

Endymion v2.2 phone is restarting on every 20 mins

Hi Guys,
I am new in this forum although I am reading specific threads almost every day. I am currently using Endymion v2.2 and I am pretty happy form it. Previously I've tried some other ROMs but I think Endy is mine ROM.
In version 2.1 it was undervolted with -50 and it was working stable on my HTC Desire S. So when I've installed v2.2 from time to time I was UV it with -50. However after restart everytime it goes back to default state. So today my phone restarted incidently (happen about once per 1 or 2 days) and I've UV it with -50. After pressing Save and Activate permanently my phone freezed. No keys were working. After that it is restarting on every 20 mins. In fact it is alive for 1-5 mins, freezing for 15 mins and restarting itself. I've tried to boot it in recovery mode and deleted all types of cache (probably bad decission) but no change. I will be very thankfull if anyone have any ideas (Alternatevelly I could try to wipe and install v2.0 from scratch since it is the only one I have on the SD card)
Thanks a lot!

I know that probably this is not the best thread for this but forum rules do not allow me to post anything on Dev forums until I have 10 post or more.

Change the U/V to -25 and if that doesn't work put them to default !
Also did you Underclock it?

I've tried with default and even with +25 (current one) but there is no difference.

I haven't overclocked it further. I am using default settings comming with v2.2 (I think by default it is OC to 1075)

Thats ok did you update OC/UV Beater2 as there were issues with newer versions above 1.5?

One interesting fact:
When phone is freezing all keys are not working. However I can call it! It gives a free signal but it doesn't rings. So maybe it is 'sleeping' somehow.....

Most probably since the problem begins when I've tried to do -50 in UV. But now according to OC/UV Beater2 UV is by default and OC is using the default setting which are comming from the ROM. I've revoke permissions to this application from Superuser but nothing changed

Any ideas how to swich off Undervolting/Overclocking?
Unfortunatelly I should be quite fast since I have usually 1-2 mins before next restart. (Today probably the phone restarted at least 20 times.)
I am also having my phone in the charger. I do know that I should not pull the battery in any case.

I have to travel so I will be back after about 3h. Since my phone is unuseful I will not be able to respond to this thread before I am getting back home.
Thanks to all for the help

Agreed, seems something wrong with of/iv beater. Please uninstall it completelly, by doing this (i assume you know how to use adb):
- reboot to recovery and connect USB cable
- adb remount
- delete the app from /data/app , don't quite recall the name, but its obvious once you see it
- delete /system/etc/init.d/98setvddconfig
- reboot
See if this helps.
Cheers
--edit--
If you don't have time, the really important part is deleting the file in /system/etc/init.d

I've just installed Android SDK and JDK Will try to delete it on next restart probably after 10-15 mins or in worst case in next-next restart - about 30 mins. Will let you know as soon as I have some more info.

I was not quick enough in first attempt (since I had less than a min). I run ES File explorer and tried to find /system. By default it was on /sdcard and I do not know how to go to root folder and then to system (hope next time to have more time before freeze)
Btw now the phone is frozen quite funny because of back button press it is vibrating
Updated:
found this on Internet: menu->settings->root options-> check "Root Explorer" Will try it on next restart
Root Explorer option is swiched on. Now it says that /system should be mount

[GOVERNOR][2.6.39.4] Hotplug for Nvidia Tegra

Hello again xda, today I want to present something tiny, but nontheless important (in my view) for our old TF101 ...
The first working HOTPLUG governor for this device!
Q: What the hell is 'hotplug' ?
Hotplug Governor:
The “hotplug” governor scales CPU frequency based on load, similar to
“ondemand”. It scales up to the highest frequency when “up_threshold”
is crossed and scales down one frequency at a time when “down_threshold”
is crossed. Unlike those governors, target frequencies are determined
by directly accessing the CPUfreq frequency table, instead of taking
some percentage of maximum available frequency.
The key difference in the “hotplug” governor is that it will disable
auxillary CPUs when the system is very idle, and enable them again once
the system becomes busy. This is achieved by averaging load over
multiple sampling periods; if CPUs were online or offlined based on a
single sampling period then thrashing will occur.
Click to expand...
Click to collapse
As you can see, hotplug is able to deliver you the fastest experience and the most fps in game (kernel independant), but it also allows for completely switching off one core to save battery life. In my testings, that worked very well. I also found out, that with this governor, my TF is deep-sleeping like a baby. No governor around here (not even smartassv2 ... could deliver me this performance while maintaining a decent battery life).
Tested on EOS 4.2.1 with EOS4 kernel
But try out yourself:
NOTE: This works on any 2.X kernel available (my Harmony series, ELiTE series, KatKernel series, or any other kernel except my divemaster)
Code:
1) Download a terminal emulator (if you don't have one already)
2) Download the .ko module from [URL="https://dl.dropbox.com/u/31119007/xda/hotplug-tegra-2/cpufreq_hotplug.ko"]here[/URL]
3) Remember the path you saved the module to (or preferably move it into /system/lib/modules)
4) su
5) insmod path-to-module/cpufreq_hotplug.ko
6) Switch to 'hotplug' governor with your favourite tool.

As always, have fun, share, and report back!

I have followed the instructions, do I have to run it every reboot or just this one off?
Nothing really happened when I ran it but I guess it just loads the module.
Cheers buddy

Must say thanks again for all the amazing work!

Running eos3 and kat69

Good work! I was trying to do this same thing the cpusleeper app but couldnt get it to work. Definitely giving this a go.
Edit: installed fine but wont survive a reboot. Any fix for e this?

Got a reboot while browsing with stock browser for five minutes.
Eos81,kat kernel

The only problem as 2 people discribe abovme is RR or Random Reboot.
Thats only problem.

sounds very promising i'll try it out and report if I get any RR's.
Getting error insmod: Can't open 'path-to-module/cpufreq_hotplug.ko'
Cd to my download folder which is where it is, am I doing something wrong?

path-to-module should be the path the the module.

Wow I derped that up, thx lol.
Was running fine at 1.2 decided to bump it up to 1.4 hit apply and it rebooted on me, is also didn't stick after reboot like others have said.

In here you may find how to make permanent the governor insmod.
Long story short is "add a script in /system/etc/init.d , it can be something like 91modules. . Add execution permission and it can contain the same code as before. Reboot and it should load your module at boot (be sure that the path to your module is right).
Also, you can do that in one line as root in a terminal. First, be sure that your /system is mounted as rw, not ro. If you don't know how to do that, as root, in a terminal, execute:
Code:
mount -o remount,rw /system
Then:
Code:
echo -e \#\!/system/bin/sh'\n'insmod [B]/path/to/module[/B]/cpufreq_hotplug.ko > /system/etc/init.d/91modules | chmod +x /system/etc/init.d/91modules
"
It should load automatically next time you reboot.
I created the 91modules file and done the editing and file permission in ES File Manager, but the above instructions should work flawlessly.
Don't thank me for this. Thank MapleSyrup

RaymaFX, you always amaze me!:victory:

Posts like this are keeping my work up and my releases coming.
People like you are the reason I am putting this much effort in this kinda old device .
For those who experience SOD/RR with hotplug and can confirm it's not related to anything else, please gimme a dsmg/ksmg (I recommend using 'Lumberjack' from the playstore (made by Chris Trotman, EOS founder).
*NO* logcat, that isn't any useful for me in this case ..
I do now have 2 days uptime with hotplug governor, not a single SOD/RR, pretty much usage (wifi on all the time, a little Riptide GP, web browsing, most of the time playing music) and still got 20% left with EOS4 kernel while achieving full performance while needed. This thing is deep-sleeping just perfectly.

I have placed the hotplug in the system this morning and my battery life still 99% im using it with dock and dono m8 but if theres any problem but seems my tf101 dont consume energy at all im starting to get scarry lol

I typed all this in and it wont survive uve a reboot. I placed the module in /system/lib/modules and typed that. When i see the | is that a new line or all one line?
Sent from my Transformer TF101 using xda premium

You can make that code in 2 commands, 1st is all before the | and 2nd the command after the |.
In order to work your final 91modules should look like
Code:
#!/system/bin/sh
insmod /system/lib/modules/cpufreq_hotplug.ko
In order to test if it's working you cat try to run it from the terminal (it may need "su" before)
Code:
./system/etc/init.d/91modules
If it's not complaining about not being executable, you may test to see if it's loaded with "lsmod".
If it's loaded it surely will survive the reboot.
I hope that helps you.

Looks like it created the 91modules file in init.d but when i try to set permissions using chmod +x it says bad mode. Maybe thats why it isnt working, wrong permissions.
Sent from my Transformer TF101 using xda premium

Indeed the chmod +x command doesn't work.
You may use ES file explorer to set file permissions but also you need to allow it superuser access, mount /system as writable and "up to root" and mark execute and write to the user. At the end the file should have the following permissions: rwx r-- r--

Ill give that a try and see if that does it. Thanks!

thanks
Thanks RaymanFX, this is a great addition to our device.
Also thanks to all your work, you are keeping this device alive...
