HTC EVO 4G :: New OTA Include Kernel That Went Out With Fresh 3.2?
Sep 23, 2010
I am about to send word to a few evo owning friends to get the update and what it includes and want to know whether I should tell them it includes the big battery saving kernel flipz included in fresh 3.2
I recently rooted my Evo using UnRevoked 3.2 and flashed Fresh 3.3 on it. I'm generally happy with the results, the upgrade seemed to fix some problems with random reboots and screen locks I was having on stock (I'm thinking that moving a lot of apps to SD may have helped, as I seemed to be always low on memory).
In any case, I do think the phone is a bit "laggy" after the update. I downloaded FPS2D and checked my FPS, seem to average right around 50fps with std dev of 9. It seems like many people are getting much better screen performance using the custom netarchy 4.1.9 kernel. I'd like to give that a try but I have a couple of basic questions...
1. I will do a nandroid backup and Titanium before I flash, but I noticed that restoring apps last time was a drag...I use FolderOrganizer and it's a pain to get them all set up the way I had them. Does flashing the kernel wipe your phone clean? How much app/Sense restoring would I have to do assuming all goes well? I'm assuming that flashing the kernel has little to no effect on installed apps or Sense screen layouts...he cried hopefully...
2. I'm assuming here that Fresh 3.3 is compatible with netarchy 4.1.9, correct? Also, I saw an indication that netarchy 5.0 may be around the corner...is it better to wait? Or is reflashing a kernel that easy so there's no reason to wait?
3. It looks like an overclocking app is included in the netarchy kernel? Is it necessary to tweak the profiles, and if so what are the recommended tweaks for best performance? I have some experience with this coming from an overclocked Palm Pre, but I care a lot more about my Evo...I don't want to hurt it!
4. Battery performance is less of a concern than screen performance for me...I have chargers everywhere. Still, I'd like to get the best battery performance I can. I believe there may be "rogue" services on my phone that are eating up the battery (for example, I use Exchange ActiveSync and I turned it off recently because sync problems were causing it to stay on in the background). What's a good way (or app) to identify rogue apps/services and kill them?
I installed the latest version of fresh last week and im loving it... My battery life is amazing now. I was just wondering if there is a big difference in performance between Fresh with the stock kernel & fresh with a custom. Did i half-ass it by only installing the new rom with no kernel? what about that set cpu app that people were using with unrevocked when the evo came out... Anyone using that still with their custom roms or is it unnecessary?
I just installed the netarchy kekrnel 188.8.131.52 w/HAVS and immediately I started to lose about 4% battery in about 15 minutes or less. Mostly idle too. Used netarchy-toastmod-184.108.40.206-havs-fresh-compatible-signed
The performance is wonderful with the fps unlock, but still the loss is insane.
I cleared my cache and dalvak cache prior to flashing the kernel.
Ive flashed with Fresh 2.1.1 and installed Systray monitor and off the bat the RAM memory was around 30 megs and otherwise performance was slower than what i was used to. I can tell its same or slightly faster than stock 1.5, but its way slower than Gumbo Kernel optimizations on fresh 1.1 When i reflashed fresh 1.1 and gumbo kernel, the available RAM went up to 86 megs and the phone became faster and usefull again.
Im afraid even when the official updates comes along, I wont be able to use it because I got used to Gumbo's speed. What are your opinions and pointers for Gumbo-like optimization of 2.1 roms?
So after a long debate of "to root" or "not to root", i decided to go ahead and root. I chose to manually root just so i could have the satisfaction of doing it myself.
I flashed Fresh 1.1 and Gumbo Kernel and LOVE the speed and the snappiness. But after a while i have been seeing some major issues.
1. Handcent does not seem to work. Everytime i get a message it either freezes up or it just automatically reboots. I just un-installed handcent and have been using the stock message app which is totally fine.
2. My phone randomly reboots to the Fresh screen.
3. NOW HERE LIES THE MAJOR PROBLEM. I try to open my browser and it says that "This applications requires network access. Enable mobile network or Wi-Fi to download data" Press "Settings" or "Cancel" First of all, my mobile network IS turned on. So i press cancel instead, and when i do, the page continues to load like normal. So i can surf the web, and everytime that box pops up, i press cancel, and i continue browsing with no problems. Now on occasion, i can open up the browser and not even get the pop-up box. So i have noticed that on the top of the screen next to where the time is on the upper right hand corner there's and icon that seems to appear when the network works fine and disappears when the network doesn't work. Now when i go to Settings>Wireless controls>Mobile Network it says, "Standby for connecting to mobile network". and when it works fine it just says, "Connected."
Why is my mobile network continuously going in and out of service?
I installed Fresh 3.2 and have used both netarchy-toasted and kings #8 (and9) kernels. With both combinations I've noticed that my battery drops 10-13% over night while i'm sleeping. I looked at Spare Parts and SystemPanel and nothing stands out, no app or service is taking over during that time. I did not have these problems when I was on the stock 2.2 unrooted setup.
I followed all the steps from [Guide] Root/ROM FAQ/Tutorial and installed Fresh. However, when the phone comes up everything is [OK] but in the bottom Initialize Fresh Rom [Wait] flashing.It keep on rebooting and comes to same point for past 30 minutes.Did I messed the rooting part or ROM installed?Is there anything can be done here? or do I wait?
I have vanilla linux kernel version 2.6.27. I want to apply android specific patches and convert it to android linux kernel 2.6.27. Where can a user find the patches to convert a normal vanilla kernel into android kernel?
I am rooted with unrevoked 3 so I tried to flash fresh 2.2 today but my phone is stuck on the screen that says "fresh" after rebooting. It's been that way for an hour. I tried pulling the battery and reflashing from the bootloader but it does the exact same thing.
1. I updated to stock 2.1 using the sprint update tool. 2. I followed the video tutorial to root the phone 3. then i used joey's page (http://www.joeyconway.com/sdx/custom/index.php) to install the his kernel (joeykrim-SDX-kernel v2.0.4 (includes root)).
I have done nothing else to the phone but this and removing a couple of bloatware apps (i checked the list of permitted deletions before i removed anything.) I have not installed a new recovery..at least i dont think that I did as part of one of the other operations I performed (as an aside, i am not really sure what the custom recovery is or what it is used for, so i didnt install it...i guess i need to read up more...)
So that is where I am..but i have a couple of questions.
1) i am now having issues with my wifi connection - the signal reception is very spotty in areas where i should have atleast 2 bars of reception, and the wifi often cuts out completely....Is there any know corellation between joey's kernel and this wifi issue? I have searched the forums and have found nothing that answers this.
2) Is there an easy way to get back to the stock kernel? I have read that i can get back to stock everything by using the sprint download center where I did my original 2.1 update. But is there a way to get back to just the stock kernel without wiping the phone?
I currently have bekit 1ghz kernet installed, but I was interested in trying out some other kernels. Can I just install them via Rom Manager over the first kernel? Or is there some kind of uninstall process I should use first?
I have a problem trying use <include /> within a table row. Any android:xxxx atributes applied to the widget within the include are ignored. Here's is a test I put together. The two buttons outside the table layout render correctly(adjusted width and height), the one's inside do not. Strangely, the custom TwoStateButton:xxxxx attributes are rendered correctly in both cases. ............
So I read the xml tricks 2 from developer.android.com, and it worked for me. But I need to programmatically include 1 xml into another. addview returns

I have downloaded the Galaxy SDK from: http://innovator.samsungmobile.com/galaxyTab.do When I try to install my app on the emulator, I get an error: "missing shared library". I think the Google maps api is not included in the emulator. Is it possible to include the api?
Is there a way to isolate just a portion of a website and feed this into an app?
For example, I'm looking to develop an app for my rugby club, I want the league to show up, but rather than direct to the RFU site, can I catch just the table itself? Here's the website to clarify matters:
