With gingerbread 2.3.6 stock I ran speedmod k2-21 with tegrak ultimate and the same phenomenal extreme voltages. Everything was ok.

Now with ICS, I was with last stock ROM XWLPF with Phenomenal 5.5 medium. It worked 100% perfect. So what happened to me It was phenomenal extreme related.The first issue was WIFI icon disabled even if it said connected. And then all the rest I wrote.

The fact I restored the backup and also wiped data twice, means that it is not ROM related and that something was damaged at the kernel level, something which was not fixable by the kernel cleaning too.

When the CPU works (much) under the stable voltages, can crash but can also write something wrong ("1" can be so "weak" to became "0"...). For me this is dangerous. In my case It damaged the kernel sector. I am not 100% sure that it can't damage a memory sector which may let the phone bricked.
[Galaxy S II Android Development] It_ler:
I agree with Karpfenhai.

IMO, it seems to be a combination of kernel + ROM + phone.

On my phone I had never such issues with any Phenomenal Extreme version ... even on ICS ROMs.

And there is already a kind of warning in the OP:
[Galaxy S II Android Development] monster75:
OK, I remain with my thought. If I have to risk something to have 30 minutes more of autonomy, I prefer the medium version.

In my case the extreme made the CPU to damage the kernel sector. Maybe I'm the first and the only one. But I am one.

Be careful my friends ;)
[Galaxy S II Android Development] Karpfenhai:
Mate, don't blame yourself :)

There is no kernel sector or such a voodoo thing..

There is memory (elusive) and a filesystem (persistent) the cpu does only compute and manage data between the fs and the memory.

Even the kernel is just a part of the fs if the device is powerless.

After start the kernel is fully loaded into memory.

So the worst case that could happen is, a part of the filesystem is set to write by the system during a crash caused by an unstable kernel, it simply writes a 0 instead of a 1, or it does lock just this block. Then we talk about a filesystem inconsistency. But by default there are some mechanism implemented to prevent such inconsistencies.

They are extremely rare, also due to the high speed of read/write operations our flash-based filesystem can handle.

So... Somewhere in your ROM a tiny single bit has struggled one of your filesystems. Maybe the one where the bootloader is stored (hidden partition).

Not your kernel, otherwise it wouldn't be loaded into memory. (checksum mismatch) a file could not be read by the system, whyever, and the system started the Android-is-upgrading routine.

Did you flash the bootloader as you flashed the stock ROM?

Conclusion, you simply had some bad luck, this can happen every time, also with a stock non rooted ROM if you pull the battery during runtime per example.

Please believe us, it's not related to the kernel, but the risk of a crash and unexpected outcome is elevated.

[Galaxy S II Android Development] monster75:

Hello.

I was using extreme versions in GB and I liked it.

But in ICS, I flashed every extreme but my phone couldn't boot and stoped at i9100 logo.

Then I flashed some mediums and same resault:(

Now I am downloading normal version and I don't hope to work.

Where is the problem?

[Galaxy S II Android Development] robertobsc:
Hi phenomeno83 and guys,

I have a doubt,

In the post of Page 43 when you teach us how to build the phenomenal you suggest us to undervolt some variables.

3 of them are regulators. Studying and coding siyah Kernel I discovered that regulators are just constraints. By undervolting them we not undervolt anything, we just tell the driver that the min voltage can be that we changed. So it doesn't change anything in battery life.

Do you know that? Do you know what else should I change to really make this undervolt work?

Thanks!
[Galaxy S II Android Development] dude0014:
Thanks a lot for your effort! Is it possible you could also compile an "Almost Extreme" version? Meaning The CPU and GPU voltages are all like "Medium", but all other voltages are like "Extreme" (Bus, Screen). I'm sure others would also appreciate this :)
[Galaxy S II Android Development] monster75:
Thanks geroxx for the work. I like also the name you chose: "light" is better than "normal" and using the same number of speedmod is better to understand the kernel used.:good:
[Galaxy S II Android Development] geroxx:
Have you used a Kernel-Cleaning-Script befor installing the zip? For me "Medium" works..

Just added a new Version called "Intensive"... Have fun :)

- geroxx -
[Galaxy S II Android Development] nmeuret:
thanks geroxx,

using Extrem version of the kernel which working great so far.

Any plan to add custom bootanimation ?
[Galaxy S II Android Development] Karpfenhai:
Just do it, works like a charm ...

Please use search for this!

@ Geroxx, i did but im used to handle such stuff manually ;)

Plain Speedmod works, but as long as i am the only one i blame my setup,not your kernel! ;)
[Galaxy S II Android Development] monster75:
Intensive seems interesting. I would like to try it. I hope to not have the same issues as with extreme :D

---------- Post added at 01:42 PM ---------- Previous post was at 01:04 PM ----------

OK I flashed the intensive and have THE SAME issue as with phenomenal Extreme 5.5: every boot I have a message saying "Updating Android...opening apps" and have the circle. It takes 2-3 seconds then It works. I tried to flash the new bootloader. Nothing...

Fortunately I have the fresh nandroid backup and know the procedure to fix everything (flash rom+wipe+kernel (MEDIUM!) and then backup restore).

This issue shows that it doesn't depend on CPU/GPU voltages...
[Galaxy S II Android Development] nmeuret:
Ok, for those who still didn't figure out how to use custom bootanimation on SpeedMod Kernel (I looked for a long time) :

http://xdaforums.com/showpost.php?p=17977695&postcount=1946

Work like a charm !!!
[Galaxy S II Android Development] pasquy85:
Intensive works great... :) Extreme hangs on boot way to often... :(
[Galaxy S II Android Development] monster75:
I decided to give the intensive another chance just to understand where is the matter with my phone.

I wiped data (!) and flashed the last official ROM again. This fixed the problem.

With a fresh official ROM I flashed the medium version. And the phone was still ok.

Then I used the Ultimate kernel cleaning, I flashed intensive again, I wiped cache, dalvik and data again.

Is there a better way than this?

I rebooted the phone, I skipped the wizard procedure (I didn't want to configure anything). Then I switched OFF.

Waited 5 minutes and then ON again...

And... It seems to work. I mean, the message didn't appear.

Maybe I'm wrong but what happens to me is caused by a shorter boot animation which makes me see the message under the S of Samung. :confused:

Now I'm gonna restore the nandroid backup. Let's see...

edit:

Everything seemed ok but now I have the display which doesn't remain ON for more then 2 seconds:D

OK, goodbye extreme and intensive :D

---------- Post added at 04:30 PM ---------- Previous post was at 04:12 PM ----------

Extreme has:

Bus voltages: 266mhz = 900mv (stock is 1000)

133mhz = 850mv (stock is 950)

Screen controller voltages = - 300mv in comparison to stock

Memory voltages = -100 mv in comparison to stock

Maybe Intensive should have less extreme settings such as:

Bus voltages: 266mhz = 950mv (stock is 1000)

133mhz = 900mv (stock is 950)

Screen controller voltages= -150mV

Memory voltages =-50mV

What do you think about it geroxx?:D
[Galaxy S II Android Development] geroxx:
Have you tried my "Medium" version? Because "Medium", "Intensive" and "Extreme" has the same BUS-Voltages...

So if "Medium" works, the problem must be the screen or memory-voltages... Please try "Medium" and let me know if it works :)

- geroxx -
[Galaxy S II Android Development] monster75:
Now I'm with Medium and everything seems OK. :good:

The Display which doesn't remain ON depends for sure on the too low voltage of intensive/extreme. -300mV is really a big undervolt.
[Galaxy S II Android Development] geroxx:
ok.. today i have no time to compile a new one.. tomorrow you will get the new version with less screen undervolting (;
[Galaxy S II Android Development] monster75:
Thank You but I didn't mean to push you to work for me only. It's just an advice. But if you make a "light intensive", please reduce also the other undervoltings such as memory and BUS one. Medium should have the stock values for memory and BUS. Intensive should be in the middle between medium and extreme.

By the way, I filmed my issues

this is what happened with your intensive at the first cold boot (the same happened to me with speedmod K3-25). From second boot seems ok.

http://youtu.be/zjruws19Rgk

and this is the issue with the message after the animation. Maybe the S animation is a bit shorter than usual?

[Galaxy S II Android Development] Karpfenhai:
.. or you ask fenomeno whether he will handle over this thread to you?

Does this work on XDA ? i guess yes.

Great work, will start a second try today ;)

...update .

Seems i found the issue, this kernel does not support init.d scripts neither Voltage Control app (max 800 mhz)

What a shame ;( i want screen off only 200 mhz by default, what did you do other then Allessandro (fenomeno) or is this related to Speedmod?

...update 2 .. Nope the scripts are not the cause, it freezes also with no changes at all ;(

I would need a helping hand, otherwise i will stuck on 5.5 .. sad..

... update 3 ...

disabling all init.d scripts (GPU + frequency) let it boot and work fine, touching the max frequency freezes instantly ..

So voltage control is out and init.d too, do you recommend SetCPU instead?

Or should i ask Hardcore (done in the meantime) ?

No one else experiencing issues like this?

[Galaxy S II Android Development] monster75:
I 've tested also a "less intensive" kernel (thanks geroxx for the effort) and still have my problems at first boot with the strange message I showed on the video. Unfortunately each time I get this message, I have to wipe data and flash the entire rom again, then the medium kernel and then restore the backup. So it's a "little" bit boring to do it every time :D

Tried also on the fresh wiped ROM and have problems with the launcher which stops working...:rolleyes:

In this case I had -50mV for the RAM and -150mV for the display (by the way the display maybe worked...) but I think still the undervolt on BUS.

IMHO undervolting RAM and BUS is the matter with my phone. I think also that undervolting RAM and BUS is very dangerous for the stability of every system. I talked about it aslo with Tegrak and thinks the same.

And I can't see how It can help to have more battery life.

Besides in my case display works about 3 hours every battery cycle which is usually 30-35 hours. It means that 90% of time It is OFF, so I don't think an undervolt of the controller (not of the display!) is so important. Reducing brightness is much more, but still for 10% of battery cycle time ;)

In the end (this is my opinion), Medium is definetly the best choice. I'm happy with it, maybe I could work with extreme voltages for CPU and GPU only, but I'm happy anyway.

Thanks Hardcore, Fenomeno and geroxx :good:
[Galaxy S II Android Development] dude0014:
Thanks geroxx! Intensive works superb! Extreme would freeze for me while browsing/youtube etc.
[Galaxy S II Android Development] geroxx:
good evening,

i have a request on you my friends. 3 or 4 testers are needed because i have to check something.. It is possible that the GPU-voltages are higher than the voltages fenomeno named in the first post. Maybe i am wrong but i want to check this :)

So please download this kernel: http://www.mediafire.com/download.php?iaizi175wbs4jo1 (based on "light" version)

After that download the free Tegrak Overclock app from the market: https://play.google.com/store/apps/details?id=com.tegrak.overclock&hl=de

Then: open app --> "Load overclock module" --> "GPU optimization" --> Now please post the Voltages from "267 MHz" and "160 MHz"

Thanks for helping. Now you can reflash the old kernel :D

I flashed hiro extreme but	I have a feeling that it is not undervolted at all.

1. All extreme kernels have very undervolted screen controller that cause defects of image on my phone. But this kernel does not show any defects.

2. No improvement of the battery life comparing to speedmod

3. The phone is often warm or hot while on phenomenal it was so rare
