EDIT: Before you do this, go into root explorer and check /system/etc/init.d - do you see "77havsvoltages" in there? You can use ADB or terminal if you want. Just do ls /system/etc/init.d and look for that file.

Ughhhhh, what the heck. Try one of these and see if they work.

Now my last question Viperboy is.....using the echo command, would these changes be permanent or would rebooting sit it back to default settings?

I just need to get the .zip working. If you reboot, the voltage levels go back to stock which is the whole point of the .zip to make the phone load the lowered voltages on startup every time.

Can you please reboot, check to make sure voltages are back to stock, try the -25mV .zip in the OP, and recheck voltages?

Yeah I just rebooted and they went back to stock!....

[EDIT]
Will try the -25 zip to see if I get better results then before!

Ok, I tried the -25 zip and got NOTHING but the same stock voltage stats. Would it work if we wiped user data and then flash the zip OR did someone already tried that?

No 77havsvoltage in init.d folder :/

You shouldn't have to do that at all.

Damn, it worked just fine for me the other day. I don't know what happened. Try one from this post please.

OK I think I got it working, just got to reboot once again to make sure it wasn't a one time thing but I did this!

I unziped the -25 zip that you posted, placed the 74havsvoltages file inside the system/etc/init.d using rootexplorer, once I did that I rebooted the phone and then ran that script to check the voltage in the terminal app and it works!

Oh and while I was writing this, I confirmed that it is permanent and that it doesn't go back to stock!

Thanks for confirming. So, it seems that something might be wrong with the update script. However, I just flashed it and it put the file in there, but it didn't change the voltages

This JUST worked yesterday. The permissions on the file in init.d is correct too. Maybe for the time being, I will just post the scripts with directions on how to move it into the right folder and figure out what's up with the .zip.

i was in the process of doing that, tried the -100 and got stuck in a bootloop though.

Yeah I figured the update script might have been messed up so that's why I figured why not do it manually and see what's up. Good job on this tweak anyways dude! I'm going to try the 50 next and see how low I get go!

-viperboy- · Apr 9, 2011

So both of you can confirm that just placing the file there works without having to change permissions on the file?

That is correct......just place the file there with root explorer and reboot!

[EDIT]
Also the -100 works perfectly on my EVO! I have no problems what so ever!

well, i'm guessing it's working for me. i'm stuck in a bootloop though, -100 is too much for me and the reset zip's aren't helping :/ and course.. i don't have the right drivers for adb right now...

Please tell me that you did a Nandroid back up! If you did, couldn't you just pull the battery out and just boot into recovery?

The reset .zip isn't working?? There is no way it shouldn't work. I don't understand the inconsistency with these .zips and scripts. I thought this mod was ready to go too. I'm sorry man.

i'm not sure what the problem is, but my phone's not happy

i'm working on it though, this is what's great about this community though

Yeah, true

I will get this figured out. Thanks for testing this, guy. Sorry it didn't work like I expected it to. I'm going to edit the OP for now. Thanks again, I hope to have this working fully soon!

-viperboy- · Apr 9, 2011

OP updated! I hope this doesn't scare anyone off, I will get this fixed shortly. Please provide me with more feedback about this. Thanks!

Thx viperboy, the -50 worked great now I'm going to try the -100...thx -50 has given me much better battery life.
