This will install undervoltage for every kernel. During flash you may choose -12.5, -25, -37.5, -50, -62.5, -75, -87.5, -100mV undervoltage or delete it. Powered by nice AROMA Installer 2.50 by amarullz​

F.A.Q.

Q: What is the undervoltage?
A: This decrease voltage of the processor.

Q: What are the advantages of this?
A: Better battery life.

Q: This will reduce performance?
A: No.

Q: Can I install it on stock ROM/kernel?
A: No. ROM must be supported init.d scripts.

Q: What kind of undervoltage I need to choose?
A: Not all chips the same. Choose what you want and what will stand the processor.

Q: How can I check what undervoltage stand my processor?
A: Choose -100mV undervoltage first. If phone boots, try system stability test. If all is ok - your chip can handle this UV. If no, flash -87.5mV, try system stability test etc. StabilityTest app here.

Q: Can I use it on other phones?
A: Yes! But your kernel must supports udervolting by vdd_levels and ROM supports init.d scripts.

Q: Why touch screen not working in AROMA?
A: Re-calibrate your screen using AROMA Installer.

Q: How do i check if I have the mod flashed correctly?
A: Using SystemTuner or look here /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

Great job, I wanted to give you a tip ... during the flash plus choose these frequencies -25, -50, -75,-100mV, add -12.5, -37.5, -62.5, -87.5 mV ... I say so, because even on "System Tuner" and other programs for non htc device Scaling is 12.5 mv :D Good job and thanks again for your Mod! :)

Will this work for the stock kernel? If it won't work then is there a recommended kernel to install (maybe faux)? A link to a kernel would be nice.

No, I think it not work with stock kernel.
It's 100% work with custom kernels. I tested it with faux and bricked. Make your choice in choosing the kernel.

Just what I was after, cheers.

Started with -75, no probs so far.

If I want -100 do I just re-flash zip and say not to all except -100 or do I need to delete anything first?

-100 caused reboot so back to -75.

Still happy with that.

Like the new installer, but although a next button appears when completedI would recommend adding a note saying Undervolt complete press next to finish.

Thanks again for this mod.

Thanks for feedback.
For me -100mV is buggy too. Fine working with -87.5mV ;)
Okey, I'm touching the installer.

-87.5uv running great for me, tried stress test and various apps.

Fingers crossed for any kind of battery saving.

    No.
    Your device maybe unstable. If this is so, you need to install smaller undervoltage.
