Root Birdmans new rom flyX

he hasn't uploaded it yet, he was but then he found a bug an now he is bughunting
 
Yeah I'm curious as to what optimizations he did to the rom and having it pre deodexed will be really nice for theming it.
 
wait so custom roms are a go on the dx? is this vanilla 2.2 rooted? idk many details, so can someone fill me in?
 
how good is SetCPU in saving battery? and what would the kernel/voltage do in terms of helping battery life? why can't we do custom kernels but we can do custom roms? whatever happened to that efuse/encrypted bootloader argument against custom roms, but now we can have custom roms?

I could drop 10% an hour without using my phone, with it underclocked i drop less than 10% in 3 hours if i don't use it.

My understanding is as follows:
  • The bootloader will refuse to flash any disk image to /system or the bootloader itself unless it is signed by Motorola.
  • The bootloader will check kernel version and flags and refuse to boot one that doesn't match what it expects.
  • The bootloader does not check the contents of /system, so we can use root to change those as we see fit.
  • /system is where all system files reside, so changing that is what a ROM does (minus the custom kernel).

Really, "ROM" is a misnomer. /system can be mounted RW, and you don't need to reflash to alter it. It's basically like the C:\Windows directory on your computer. "ROM" is a carry-over from when phones were less similar to desktop computers (technically, from back when it really was read-only memory). Nowadays, they're basically identical with the exception of motherboard and CPU architecture.

If you dont mind could you please list your set cpu settings
This would be a great help to all of us. I too drop 10% an hour sometimes without doing anything.


Mastermind seems that people are having good luck with this setup Temp > 49.8 C: 300mhz max, priority 100
Charging/Full: 1000mhz max, priority 98
Screen Off: 300mhz max, priority 92
Battery < 40%: 800mhz max, priority 50
Battery < 25%: 600mhz max, priority 65

10% an hour of non use isn't right. I don't use setcpu and the 10% per 3 hours is about right for me.

The CPU clock speed is dynamic to start with and can easily drop to almost zero when sleeping. How do you know your, "under clock", isn't really and over clock? In other words if you have it set to say 300 you may actually be preventing it from dropping lower? Or is what you enter the max clock speed?

Oh I see from the above post its the max....
Which leads me to my next question. Why buy a 1ghz processor if you are going to underclock it? I'd rather have it run full speed and buy a charger... But that's just me

I'd really like to see someone do an actually test with and without do see if it really does help.Frankly I don't see how they could help unless you have an app that's preventing your phone from sleeping and if that's the case I'd remove the app not cripple all the others.
Well..... I guess it would save battery if it's under clocked with the screen on, but like I said I'd rather buy a charger or have it set up to manually turn it on if I don't have access to a recharge and won't for some time. I mean I bought a 1ghz phone for a reason and it wasn't to make it a 500Mhz one.. :-)
 
I have mine set the same way and has lasted almost 3 days so compared to how it worked before I can say it is a big improvement.

Agree, I want my 1ghz phone to run AT LEAST 1ghz. I actually have mine overclocked to 1.1 and undervolted (the main reason for it) but I stay away from setCPU profiles. The only one I have is screen off 300 max/min and thats only recent to kind of test the results.

I have no interest in decreasing speeds as my battery drops for the purpose of making it last longer.

I really like being able to underclock it as the battery gets too low to conserve it. My thoughts being when I'm stuck out somewhere and it's not feasible to charge it, I know I can get it to last until I get home. I would rather a slightly slower phone that I can still use then a faster phone that won't let me make a call....
 
Undervolting is a good idea, but underclocking makes me wonder. CPU power use and clock speed aren't linearly related, running at 300 MHz uses much more than 30% of the power that 1 GHz requires. So if you underclock you force the CPU to stay running for much longer, which should increase power use. You also keep your screen on longer, SD card powered up, NAND in use, etc..

Besides, the CPU handles underclocking automatically. If 300 MHz would suffice for a quick calculation then it won't clock up to 1 GHz. Normally I'm a proponent of manual control for advance users, but in this case there'd be very few situations where it'd help since the changes are millisecond-to-millisecond. Perhaps if you had a process using 100% CPU at all time it'd help, but that's not really something you'd want if you care about battery life.

This thread has gone waaay off topic, but since we are talking about it, how do you undervolt the X?

Two words
Bigger battery:D

oh and where is that ROM Mr_Birdman?
