News: Sprint HTC Hero Kernel Released and Compiled [Updated]
HTC has finally released the source for our kernel! We still don’t know if this includes 100% of everything because they aren’t required to release closed source code. There is currently speculation that the power saving module they used is closed source which means the phone won’t sleep properly while the screen is off (that brings back bad memories).
I just wanted to post and say that I have successfully compiled it (thanks to toast for the pep talk 
) and I am currently running a beta of fresh rom that is using the new kernel. While it is 100% stock and no changes have been made to it, this test will help show what we can do with it! Keep an eye out for exciting things.
Update 01/23/10:
Not too much progress yet… I have been working an insane amount of hours this weekend. But I wanted to let you guys know that it seems as if I got setcpu working. I am talking with the developer but it is definitely limiting the CPU with some modifications to the kernel.
The down side is I can say for sure that there are power issues just as we suspected. HTC’s custom sleep mode is not included in the kernel, so we need to figure out what to do about that. The power isn’t horrible, but I did get 60% drain in about 24 hours with medium use.

This is great news. what will be possible with this source code and will it be able to be used in conjunction with what we are used to seeing on the current Hero Roms?

the source code is what was missing to finish/fix all the missing compnents of the 2.0.1 and 2.1 Dev builds.
No guarrantee this will fix them all, but it gives us a lot of hope. We won’t know much until flipz and others get a chance to mess with it.

I don’t really get a ring lag as much as my phone just wont let me slide down to answer if it’s locked I have to slide it down at least 5-6 times to answer the phone anyone else have this problem?

I have never experienced this. Are you using a 3rd party lockscreen?

No 3rd party lockscreen just an image from Noj. It is a really weird thing sometimes it lets me answer the 1st time I slide it down and other times I can slide it 10+ times and it makes me miss the call because it won’t slidebut most of the time I have to slide it about 4-5 times to answer a call

I would definitely recommend doing a data wipe and see if that resolves the issue for you. That is for sure a software issue but it doesn’t happen with a stock fresh rom so there must be a mod or app that is installed that’s causing it.

This deals with how long it takes your phone to realize that the tower is calling it. This is modifiable, but the “30 second countdown” before a call goes to voicemail shouldn’t start until your phone actually starts ringing. I have tested this extensively and while my my phone doesn’t start ringing until 2 rings, it still rings 4-5 times on the other end which is the normal amount before it goes to voicemail.

Yes, but what that means is that the Hero owner only has 2 to 3 rings to answer it before it goes to vmail, or until the caller hangs up… that’s been my experience and one of my few gripes left since I installed your fresh rom 1.1

I can assure you that this is not a fresh rom issue because I even tested this on stock. And no what I was saying was that AFTER the phone starts ringing the caller still gets 4-5 rings before it goes to voicemail. Because it is a sprint issue, not a phone issue.

This is in the stock Rom too. The answer is over on androidforums.com. it has resolved it for me. Just look under the Sprint hero forum. Involves getting you mal from sprunt but even that was pretty easy.

i noticed when messing with quick system info that the cpu speed would vary from 480-528 but not in a reasonable way. even under stress such as playing raging thunder it would continue to switch back and forth.
just my .02 cents.
i cant wait for even a stock rom with set cpu support. i will donate friday!

Just to prove its functionality:
I’m also happy to report that I am getting much better battery life out of it with setcpu going. 7% battery loss in 11 hours under light usage. That is leaps and bounds above where we were at!

Flipz, what are your preferred setcpu settings?
Like or Dislike:

I have mine set to 528 max and 245 min. I have found that any setting below 245 drops it down to 19 MIPS making it almost completely unusable. So you can’t go below 245. But that has really helped battery life. Although we don’t seem to be able to go over 528 with either setcpu or overclocking widget.

Just curious, what change did you make to allow setcpu to work? I have tried all freq scaling options but none of them want to build correctly. Well I got performance to build correctly however the cpu stayed at 480, never went up or down. Any help would be greatly appreciated.

I believe the msm 7600 is capable of 600mhz right? Have you tried changing the max clock in sys/devices/cpu files? I wonder if that would work

On a side note, the differences listed between the cpu in this phone and the one in the euro hero is that our cpu can do both cdma and gsm. Does that mean with this kernel we could possibly have a sprint hero switched to gsm in the future?

I was hoping I would have it done last week but it turns out that was a little too optimistic.
Yesterday I cleaned all the code up to help me figure out how close the code is to being done and to help me prepare for release. I’ll try to get a better estimate soon. A lot of it is done, but there is still a whole lot to go.
