Q:

What is SBC?

A: SBC stands for super battery charger. SBC is trickle charging, It stops your battery from dropping from 100% to 90% right when you take it off the charger. Some say that it harms your battery but i haven't seen any harm and plus it only costs $5 to get a new battery on Amazon.

Q:

How to set up and flash your roms and kernels?

A: well my friend "Crossrocker" made a guide for this with everything you need. so just click to go to his thread. [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.

Q:

What is the difference between governors?

A: This Thread by "RJackson" explains it all:SetCPU governors (explained)

But if you're too lazy to click it here they are:

As explaind by RJackson:

ondemand - Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed. - SetCPU website

conservative - Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery. - SetCPU website

performance - Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking. - SetCPU website

powersave - Available in some kernels. It will keep the CPU running at the "min" set value at all times. - SetCPU website

userspace

A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor. - SetCPU website

Interactive - The 'interactive' governor has a different approach. Instead of sampling the cpu

at a specified rate, the governor will scale the cpu frequency up when coming

out of idle. When the cpu comes out of idle, a timer is configured to fire

within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer

fires then we assume the cpu is underpowered and ramp to MAX speed.

If the cpu was not 100% busy, then the governor evaluates the cpu load over the

last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down

to.

As explained by MDJ:

SMARTASS GOVERNOR - is based on the concept of the interactive governor.

I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.

Smartass will also cap the max frequency when sleeping to 245Mhz (or if your min frequency is higher than 245 - why?! - it will cap it to your min frequency). Lets take for example the 998/245 kernel, it will sleep at 245. No need for sleep profiles any more![/QUOTE]

As explained by teh roxxorz:

Lagfree - like the performance governor. It will scale the cpu to higher frequencies when needed, but not to 100% like performance, so you'll get a lil better battery out of it

SmartassV2 - A smarter smartass governor. Code was re-managed/removed to make it more optimized, and have better scaling performances

InteractiveX - a better interactive governor I believe; low scale cpu settings, for texting, browsing, ect, nothing intensive. I wouldn't use it for emulators, ect.

Q:

Do you need PRL/Profile/Radio updates? Do you need to go back to sense based to do these still?

A: No you don't have to go back to sense to do these and you don't have to do these because Rom's will come with what you need. None the less if you would like to update your radios here is a thread by "Calkulin" where he keeps the latest radios updated: [ Radios ][ 9-5 ] All EVO Radio, WiMAX, PRI, NV & HBoot versions

Q:

Does HDMI mirroring work on these roms?

A: As of this moment Miui and CM7 both have HDMI mirroring working, and sense all the other ones are cm7 with some tweaks they as well have HDMI working however from what i have read the only one that has not had problems with HDMI is Decks Gingerbread Rom

Q:

Are all other major features (4G (except for Miui), bluetooth, front & rear camera, GPS, apps such as Netflix, Skype, Google Voice, Sprint Visual voicemail) all working at least as well as on a Sense or stock ROM?

A: Yes everything is working, however on CM7 and i presume on some others you also have to flash a gps fix which you can get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration. and the Voicemail seems to have some issues for some people but works flawlessly on Decks with it's gapps + Voicemail which you may also get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.

Q:

My wifi is connecting/disconnecting after a second, what should i do?

A: This answer was given to me by "teh roxxorz." This has nothing to do with your rom or kernel, do this:

Back up everything into Titanium Backup

Boot into recovery

wipe cache, Dalvik, and pretty much everything

reflash your rom,kernel and gapps (or if you would like to check out some other roms and kernels just click on the link in my sig)

once you've set up your phone download Titanium Backup from the market

in titanium backup restore all your apps ONLY!!! (don't get apps w/ data - only get apps, and do not get system data)

after this your wifi should be working just fine

Q:

I am having wake issues?

A: Here is a Guide made by JBabey[FIX] Wake Issue (Android OS) - Combination of Radio/PRI/NV/Wimax/GPS !Solved!

Q:

Can i make my 3g speed faster?

A: Yes, This answer was given to me by teh roxxorz:

You need to flash a sprint sense rom. I emphasize sprint because it won't work on the sense 3.5 roms, as they're all ports of other non sprint roms.

1. Flash sense rom

2. Obtain your msl, download msl reader from market, use it, write it down

3. type in ##3282# , input your msl (you can get this from the app msl reader)

4. Click edit mode > advanced

5. Scroll down to HHTD proxy port and address

6. Change the proxy port to 0 and proxychange the address to 0.0.0.

Q:

How can I fix my GPS?

A: This answer was given to me by teh roxxorz:

- flash a sense rom

- open up the dialer

- Type ##GPSCLRX# or ##4772579#

- Your enter your MSL at the prompt

- Your phone will soon reboot > done

Q:

Is there a guide like this but for sense roms?

A: Yes if you are looking for a sense guide rather than aosp then check out this thread by tropicalbrit

Q:

What is your setup at the moment?

A: Rom - Decks 4.0.3 Pre-Alpha 7 ICS Rom

Kernel - Stock

Governor - Conservative

CPU Max/Min Frequency - 729/128

IncrediControl (app) - (-100) [I get to (-100) by first doing (-75) and leaving it there for 3 days and then I do another (-25)]

Car-o-Dope (CoD) setup
