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.

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 Good job and thanks again for your Mod!
