HTC EVO 4G :: Big Difference B/w Kernel / Fresh With A Custom?
Aug 27, 2010
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 use Baked Snack 1.7 and I tried the deodexed version of the OTA but noticed no change. Infact I found the OTA would stutter sometimes when scrolling. Also compared to CM6 and Neterchy kernel 4.1.9.1 I don't see it being same or better besides it being official. I know pretty soon the devs will have their own version but for now I don't see a reason to update.

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 just installed the netarchy kekrnel 4.1.9.1 w/HAVS and immediately I started to lose about 4% battery in about 15 minutes or less. Mostly idle too. Used netarchy-toastmod-4.1.9.1-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.
I am running the Fresh 3.2 rom.

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?

1) What is the difference between kernel and a ROM? How do I know what kernel I am on? I know I am running the SholesMod ROM, but I am considering changing to another ROM. I seem to have FC's quite often and am trying to fix that. If I want to change a ROM will I need to change the kernel to make sure they are compatible?
2) I have SP Recovery installed. Is this part of the kernel? Is this installed in a separate place from the kernel/ROM? I'd like to feel assured that if I am installing a new kernel/ROM and something goes wrong, I don't have to worry about my SP Recovery being affected. But should I?...............
3) Nandroid backup... does this include everything on the device? Kernel, ROM, AND Recovery Mode?
I'm a newbie to hacking the Droid, but back in my PSP days, I know that the Recovery mode was stored on the same drive as the system files, and if you make a misstep when flashing a new firmware, you could lose recovery access. I'm just wondering where the recovery is located in the phones file system, and if I should really be concerned when flashing ROMs/kernels. Also, is there any way I could redirect it to load recovery from the memory stick, if the default recovery cannot load, just as a failsafe? Or if I lose recovery, could I somehow flash a new recovery via USB?

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 just went through the process of compiling a custom ROM and they used a stock kernel. I would like to incorporate a different kernel when I compile and instead of the stock. I know I could compile them separately and have them flash together but I want one zip to flash. Just would like to go through the process to learn.
what I have to do when compiling?'

I was wondering if I can flash Netarchy Toastmod Beta: 4.1.9.1 w/HAVS on this newly released OTA rom from XDA? I don't like how the stock kernel has been acting since I installed it. Would this be ok to do?

Issue is that I freeze at any speed over 604 max (via Setcpu). Tried setting higher speeds as a charge profile to see if being triggered would change yet didn't. I have done nothing with advanced menu as I have found nothing posted referencing it netting higher speeds. I am rooted, started with zanfur kernel, switched to a conap kernel (bfsv6), both with same results. Did dalvik wipe (i am running amon ra) then went back to zanfur kernel to try again, same results. What am I missing? If this is just equipment limit then what's the result of flashing a custom Rom with default clocks of 710+++?

So I finally rooted my droid, installed BB 0.4 and from what I understand it comes with an 800 MHz kernel. Fair enough but lets say I want 1 GHz. I'm already noticing that I get slightly less battery life with this than with stock 2.1, so would the "low voltage" or "ultra low voltage" Chevy kernels provide me with more battery life? I know I should probably get SetCPU, but I don't want to constantly have to manage clock speeds manually and I don't know what profiles to set / what's safe and what's not safe and whatnot.If I DON'T install SetCPU, will the phone take care of it by itself and slow the clock down when it's not doing intense tasks and so forth? Is SetCPU really necessary with a kernel or is it just for extra control for super power users?

They tell me this will change again when the Droid X and Samsung Galaxy get 2.2 - I wouldn't know. Until then, here's our moment in the sun. Made this using the Quadrant benchmark, free from the Market, using a the stock rooted 2.2 rom and the netarchy-toastmod 3.7.6c kernel with the 30 fps cap lifted. No over-clocking, no hair-on-fire super tweaks, no killing every process to tweak the benchmark - just downloaded and run, the number on the bar says 1165.

The Nexus One 2.2 at the top uses the exact same processor (aside from the radio-control circuit) as our EVO. I attribute its higher score to the fact that it's sleeker and not running Sense. I happen to like Sense so I don't care.
