Just thought I would chime in here to state I'm using Alpha 7 on CleanRom ULE with no issues. So far Alpha 7 seems very smooth. Cannot comment on battery life as I've not run it long enough. But will update this post once I get a better picture of battery life.
[Verizon Samsung Galaxy S III] suzook:
Do the CMX kernels have improved colors also? Just curious before I flash. Thanks

Will Alpha 7 in the listed in the Op work with CleanRom 2.5?
[Verizon Samsung Galaxy S III] prdog1:
Been running Synergy 64 with Alpha 7 at 1.7 since the initial release of Trinity Alpha 7. Have had no problems with rom or kernel. Wipe till raw and do not dirty flash anything.

It should since Cleanrom is basically stock. Clean kernel should work fine also.
[Verizon Samsung Galaxy S III] annoyingduck:
Been on synergy R73 since it's release with trinity alpha 7 added on about 2 weeks ago. Smooth, stable, fast, better battery life than synergy stock kernel. I haven't even tweaked it yet with the trinity toolbox app other than some overclocking play arounds. Life is good at this moment.

Hey Duck. Think the dirty flashing is catching up with them. :laugh::cool:
[Verizon Samsung Galaxy S III] annoyingduck:
Quite possible, but then again who knows what was done prior... :confused:

I'm a big fan of dirty flashing (if you know what/why your doing it), but only on same base upgrades, but then again I'm very impatient! That extra 20 min for titanium to restore is agony when I want to play with something new! :D

[Verizon Samsung Galaxy S III] prdog1:
Key is what/why/when. You can also wipe system/dalvic/cache. Leave data alone and have the same as clean rom flash. Still get all apps back but get clean rom.:cool:
[Verizon Samsung Galaxy S III] annoyingduck:
Hells yeah..!

Can confirm too with shibbys post a little ways back on not being able to boot up when charging. Reboots are fine, total power down then powering up is a no go when connected to usb/wall.

Kind of interesting, seeing as fast charge does not appear to be working (no ability for me to test, hoping someone does).

Possible relation of the two?

Sent from my VZW GS3 running Synergy/Trinity/Dark Horse Rises
[Verizon Samsung Galaxy S III] prdog1:
No boot while charging. Never have tried or need fast usb charge so don't know the correlation. Also as far as dirty flash as long as you stay on Synergy Ech wipes system and cache for you. That is why dirty flash is allowed. On Mik roms we wipe everything for you. Unless you can edit update script you get to save nothing. Cuts down on rom complaints and troubleshooting time. lol
[Verizon Samsung Galaxy S III] annoyingduck:
Above you mentioned wiping system/cache/dalvik does not remove apps? It does when I do it. Is there a way to wipe system without the factory reset that I am missing? All my clean installs have always required an app restore.
[Verizon Samsung Galaxy S III] prdog1:
Don't do the factory reset. That wipes data+dalvic+cache. Just do dalvic/cache/ system. Or wipe all and do data only restore from nandroid. Since not wiping data will be a semi clean install. System is where the rom is and what causes the biggest problems. If they add files to rom it is no problem. It is when they delete or rename files that causes the problem. The files that don't match will be incorporated from the old rom. They will not be overwritten by new rom if there is no matching file. Or the files they remove will still be there from old rom because there is no file to overwrite it.

If you are using Clockwork you have to go to advanced/mounts or something like that to wipe system. It is not on the same page. Haven't used clockwork since Tbolt days. Factory reset does not wipe system that is why you can still boot to rom without apps. If you wipe system you have to flash new rom or it will not boot because there is nothing to boot.
[Verizon Samsung Galaxy S III] annoyingduck:
Fully understand the mechanics, but unclear as to how you can wipe the system without doing a factory reset? The two are tied together in cwm (not familiar with twrp).

Clean to me is wipe system-factory reset/cache/dalvik.

Dirty is cache/dalvik

And then changing android versions is all above + format system.

Have I been duped all these years..... :o

Sent from my VZW GS3 running Synergy/Trinity/Dark Horse Rises
[Verizon Samsung Galaxy S III] prdog1:
Skip the factory reset and do the format system. Factory reset does not wipe system partition only data partition. Data and system are two separate partitions

TWRP has factory reset/cache/dalvic/system all on main page. Do the same wipe all except factory reset.

Your clean flash is a dirty flash. When you add the system format then you did a clean flash.;)
[Verizon Samsung Galaxy S III] annoyingduck:
Awesome stuff there. Love this sh*t. Never knew that, always assumed format system was a full wipe of everything, including backups, media, and all the files that remain after a factory reset. I have never used that option before, was afraid of it!

Sent from my VZW GS3 running Synergy/Trinity/Dark Horse Rises
[Verizon Samsung Galaxy S III] prdog1:
That is why Ech does it for you. He knows better. He formats system and cache on all roms. He justs lets you think you are dirty flashing cause most dont watch the script run and all that can happen by not wiping data is apps FC.:laugh:
[Verizon Samsung Galaxy S III] BenMGP:
It was the kernel causing the reverse landscape. I wiped and reflashed 3 times just to be sure it was the culprit. Sucks because I really dug Trinity kernel on my Nexus 7.

Sorry we hijacked Morfic but we been bored and maybe they learned something. lol ;)

Works fine on ours. lol Sure you wasn't on another kernel from flashing another rom.
[Verizon Samsung Galaxy S III] BenMGP:
I haven't tried any other ROMs or kernels.

I wiped. Flashed r64, booted and everything was fine.

Flashed Alpha 7 and it goes upside down. Repeated 2 more times to be sure.

[Verizon Samsung Galaxy S III] annoyingduck:
Ok, so I think it's safe to say usb fast charge is not working. I performed a comparison test doing this:

I turned on gps with usb plugged into cpu (as this is scenero when fc is needed), screen on nothing else running. Watched for 30 mins at 50% battery. Phone gained 1% approx every 4 mins.

Same exact test but device around 55%, enabled fast charge in trinity toolbox. Exact same charge rate.

This is not technical by any means, but think the results speak for themselves.

any way to fix the upside rotation on alpha7 and cleanrom 2.1?
[Verizon Samsung Galaxy S III] dogredwing1:

:confused:
[Verizon Samsung Galaxy S III] SlimSnoopOS:
The most I could suggest is to reflash the rom then try this kernel freshly downloaded again. I've been on CleanRom 2.1 for weeks and this kernel works fine for me. I've switched kernels just to test stuff and my rotation works fine every time.

[Verizon Samsung Galaxy S III] morfic:
So noone else has the upside down issue?

Only TMO kernels should cause this on VZW.

Unless your rom base doesn't match the one specified and Samsung flipped vzw in rom and kernel since....

That's SEC, kernel side logging, i'm not touching debugfs since it's a treasure chest of information.

Debugging they use to develop the kernel/phone and shouldn't be on a release kernel.

[Verizon Samsung Galaxy S III] SlimSnoopOS:
I haven't checked since Thursday but there's no Samsung source release so that's a no. That's why kernels have been updated only through G1. G7 and newer may have custom kernel compatibility issues until then.

Are you on G7 rom or newer? If so, that Wi-Fi issue may be due to kernel being F2 and G1 based like I said above. If on G1 rom, that's definitely unusual.

[Verizon Samsung Galaxy S III] GideonX:
Ok, here we go with try #2 :)

With morfic's blessing, here's the continuation of Trinity in another form.

I was unfortunately forced to move over to VZW due to work and ended up with the SGS3. I sorely missed Trinity's touch on my Galaxy Nexus. So after a month or two of prodding morfic with kernel building questions, here's the first public release of my BMS 4.2 kernel for d2vzw. A lot of what I've done has been influenced by Trinity, so hopefully this lives up to expectations.

Some highlights:

- Based on CM10.1 source

- Built with Linaro GCC 4.7

- Ramdisk tweaked (init.d support, unsecure)

- OC up to 1.8Ghz

- GPU OC to 480Mhz

- Undervolted

- Defaults to tweaked ondemand governor and deadline scheduler

- Removal of mpdecision, uses tweaked auto_hotplug driver by thalamus instead

- Removal of thermald

- fix_permissions added to zip

To do:

- Add Trinity color values

- Voltage control

- Fast Charge

- Compile optimizations

To install (no need to wipe anything):

- Download .zip below and place on your internal or external sdcard

- Reboot into CWM or the recommended TWRP 2.3.3.0

- Flash .zip

- Reboot

I've pushed my build towards battery savings and it's been handling duties pretty well. Let me know how it works out for you. As with all things custom, please take all precautions (backups). Tested against AOKP and LiquidSmooth so far. Please let me know if you run into any issues.

Feel free to use your preferred kernel app for adjustments.
