[LG Optimus Black] Huexxx:
HOW TO CORRECTLY ADJUST THE VOLTAGE

With the introduction of the new s2.7 kernels, now you have three possibilites to adjust your phone's voltage, in addition to the voltage tweak provided on ZeusTweaker.

Before begin, a brief explanation about the two different ways to adjust the voltage. With ZeusTweaker's coltage tweak, you can lower the voltage OF ALL THE FREQUENCIES AT A TIME on runtime, while with the different kernels, you can apply a different coltage profile to freqs lower than 1GHz.

Optimal adjustment

The optimal way to configure your voltages is the following:

- Reset voltage tweak to 0 on ZT.

- Enable fsync().

- Set your desired frequencies.

- Make a nandroid backup through CWM.

- Install kernel s2.7.

- Lower the voltage one step at a time, testing each value:

-- Launching Auntutu or Quadrant.

-- Reboot with that value to ensure that the phone correctly boots.

-- Play your usual games, or use your usual or needded apps.

- With a certain voltage value, you will experiment some kind of 'trouble', as:

-- Loading Auntutu id doesn't show the logo, only the text.

-- Reboots.

-- Freezings.

-- SoDs.

-- Lags.

- Once you have suffered the problems, your optimal voltage value is the result of adding 2 to the problematic value.

- Set that optimal value as voltage tweak on ZeusTweaker.

- Flash the kernel s2.7medUV.

- Repeat all the testings with the new kernel and optimal voltage value.

--> If you get problems, reflash s2.7 and stuck with it.

--> If it flawlessly runs, continue with the process.

- Flash kernel s2.7maxUV.

- Repeat all the testings with the new kernel and optimal voltage value.

--> If you get problems, reflash s2.7medUV and stuck with it.

--> If it flawlessly runs, stuck with s2.7maxUV.

If you afterwards modify your min/max frequencies, IF MORE OPPS ARE ADDED (lowering the min or raising the max), you should repeat the entire process, although begin from coltage 0 is not needed. It should work without modifying it, but if problems arise, redo all the process but beggining from optimal+2.

Thorough check

How to check that the phone will work fine with all freqs? You can make individual tests with each freq.

- Set performance governor.

- Make testing:

-- Launching Auntutu or Quadrant.

-- Reboot with that value to ensure that the phone correctly boots.

-- Play your usual games, or use your usual or needded apps.

-- Check that is working problem-free.

- Lower the freq a step and repeat.

You only can test that until 300MHz becuase you cannot set 200 and 100 as max freq. If everything goes fine but you still encounter problems like SoDs, the problem probably is on <300 freqs, so you should use the previous kernel in terms of UV (medUV if you ar on maxUV, normal if you ar on medUV), or limit your min freq to a higher one (200 or 300).

Why I cannot get my phone working wiht others values?

Each mobile/proccessor is different, so the results are different too.

Why I have SoDs problems if benchmarks go fine?

When you launch a benchmark test, the phone usually works on its max freq, while the SoDs usually happens with minimal or close to min freqs. Maybe in your case and config, voltage to max freq is enough, but is too low for min freq.

If I flash a kernel with more UV, I encounter problems with optimal voltage, but raising it a bit, everything goes fine... why to stuck on previous kernel?

The set voltage with SeusTweaker will modify voltage for all freqs, so, using a kernel with more UV, if you raise the voltage tweak to get it working, you will be rasing the voltage for the max freq, and that freq is expected to have a higher battery draining. To drain battery a bit less on standby at the expense of drain more on max activity is not a good idea.

Why should I install kernel s2.7 if s2.6 or s2.3light is working fine?

- Kernel s2.3light is good but older, and is less optimized. Kernel s2.6 has some kind of smartreflex problem, and although you don't feel nothing wrong, it's not working as it should. In other hand, on both older kernels, voltages for freqs >1000 haven't been raised, so if you use those freqs, you should have to use a higher that optimal voltage tweak value, with the subsequent extra battery draining. Please, of you are on the group of people that had problems with s2.6light, and you returned to s2.6, TRY new s2.7, the normal one, to see if your problems are gone too.

I hope this will solve certain doubts...
