Information regarding creation of a custom ROM

Hey, new to the forums, recently purchased a GSM Hero.
I have done some development for free software (think freedom, not price) projects, and have become accustomed to git repositories and structured development.
Upon entering the world of custom Android ROMs (at least Hero ROMs) I have been sorely disappointed with the development practices going on, releases on file sharing sites and the like.
On top of this, none of the ROMs available suit my needs.
This is all fine, as I'm not developing those ROMs.
I have decided that I need to start working on my own custom ROM, however guides and documentation regarding this process are in short supply.
It would be much appreciated if someone could link me to some guides to starting my own custom ROM.
I intend it to be a light vanilla ROM, with none of the bloat that seems to perpetuate other ROMs, I'm aware other such ROMs do exist, however none of them support all features, and even those that claim to do so, often require me to FC

Have you tried this one ? >[2.1] aychteesees-vanilla-cupcake< NOT the [3.0.1]verison ..this is still @dev
http://android.modaco.com/content/h...96/3-0-1-aychteesees-vanilla-cupcake-rom-gsm/
Give it a try [2.1] ! and tell us how it went ...

Yeah I tried that one, it claims to have full functionality, however I frequently had to FC various applications.
I'm downloading 3.0.1 as we speak, however I'd still like some resources on making my own ROM.

I'm interested on this documentation too....thanks

That's weird , I have used almost everything ( apps ) with that ROM [2.1] ... and never get FC's
Did you flashed from Zero .. I mean with all he possible wiping . inlcuding SD ext partition wipe
???
That is a MUST ..!

Before this gets too off-topic, I too would like to concur with what OP is saying. I'd love some info on where to begin with custom ROMs, and I think it would be great if we could create a community repo for code for a custom ROM.
This leads me to another question: all these custom ROMs that we see available for download -- are they free/open source? Like, do they have source code available? I certainly don't think they do, but if they don't, then aren't they violating the terms of the GPL by not providing source code?

There's Paul's (modaco) online kitchen, but if you want to compile by yourself, there's a plethora of gits on github (cyanogen, lokx, kiall to mention just a few).

Good question. Yeah it would be nice if there was a 'Cooking Class' thread on this forum like in some of the other forums. There is a decent tutorial however at HTCpedia.com under the HTC Hero ROM Development section, it's in the stickies there. However, I still have questions and that forum is not visited as much as xda.

As a start, I would read that thread I just linked above. Once you can dump the contents inside the system.img and then combine it with the boot.img to build an update.zip, then you are already halfway there - that's actually fairly easy. But knowing how to add custom kernels to the update.zip, making the custom ROM rooted, etc. are all stuff that I'm still working on. There's supposed to be a lot of info in the Dream/Magic forums, so I'll keep reading.
Android is still fairly new and very few people know how to use Linux, thus there's less support and less interest in wanting to cook for one's own Android device.
BTW, that thread I linked above is also found here.. Doh!
http://forum.xda-developers.com/showthread.php?t=551711

Thanks for the link, a good read.
Anyone know what the process is for using a custom kernel? There are a few things I'l like to enable that aren't in the HTC kernel (like FUSE).

If I eventually manage to find out I will post it here. My most important concern is making a rooted ROM from those shipped ROMs, as some people have been doing here.

30/Jun r1 (JFB) - MoDaCo Custom ROM for Samsung Galaxy S with Online Kitchen

I'm pleased to present my MoDaCo Custom ROM for the Samsung Galaxy S! READ THIS WHOLE POST BEFORE YOU START! No, really, it contains everything you need to know. wink.gif
This ROM is the 'starting point' for my Galaxy S custom ROMs.
About MoDaCo Custom ROMs
MoDaCo Custom ROMs are based on official ROMs - either shipping or leaked. A MCR release is designed to feel as far as possible like a stock ROM, with optimisations, tweaks and complimentary additions that enhance the user experience. The aim of a MCR is to be ultra reliable for use on an everyday device.
Requirements
In order to use this ROM on your device, YOU MUST ALREADY BE RUNNING THE JFB ROM FROM HERE. Do NOT use this ROM with any other base, unpredictable things will happen, the most likely being you'll have to reflash your device via Odin.
Features Included
* Based on the JFB release
* Rooted with Superuser 2.1 by ChainsDD
* Built with the MCR build process which reduces the size and boosts the speed of the ROM
* busybox with Droid Explorer support
* Updated Google Maps
* MCR version displayed in 'About' screen
* Optional Google Voice Search
* Optional Google Voice Dialer
* Optional Fancy Widget
* Optional Beebplayer
* Optional baked in Wavesecure via the online kitchen (installed to system partition for maximum security)
Changelog
Please see 2 posts below this one for the changes in each release.
Installation
To install this ROM:
* Ensure you have the JFB ROM installed (linked above)
* Download the zip file of your choice from the links below (or the online kitchen) and copy to your SD card named 'update.zip'
* Restart your device in recovery mode by running 'adb reboot recovery' (download adb if you do not have it already, use adb-windows, adb-mac or adb-linux as appropriate)
* Select the option to apply an update zip, and select the zip file you copied to your memory card
Upgrading
No wipe is explicitly required in order to use this ROM, however if you do encounter issues of any kind, it is recommended that you wipe your device and reproduce the issue before raising it here.
Downloads
This ROM is currently only available in the online kitchen - prebakes to follow.
Thanks
It's impossible to mention everyone who contributes to the Android community by name, but to everyone out there who does great work and shares it with us all - you have my gratitude and respect.
And finally...
If you would like to show your appreciation for the ROM, please consider supporting MoDaCo by signing up for a MoDaCo Ad Free or MoDaCo Plus account, both of which also give you early access to Beta ROM releases and access to the the online kitchens.
Enjoy!

Does this ROM fix the ram issue so that all 512MB of ram is utilized?
Congrats on being the first custom rom here.

Congratulations! I don't have a phone yet but I am very pleased to see a custom rom already!

woohoo custom ROMs already. Guess I'll be getting myself the phone after all.

umm.. but in another thread people where saying that it wasn't gonna be possible because samsung encrypt their drivers etc. so this mean they did release they drivers? and there is gonna be alot of custom rooms for galaxy gravity?

No I said it would be near impossible to get roms from other sources like Sense roms or Froyo on because of the driver issue. I never said you would never see custom roms. The only roms you are going to see are one's based off of Samsungs release.

Hold on, hold on. So even though Samsung released the Galaxy S' driver source code to the public, it's going to be "near impossible" to port Sense and FroYo to the phone? I may be ignorant but I'll just ask with ignorance, how do you figure?

Download the source code..... ok now open it and go to GalaxyS_Kernel.tar.gz. Now in there just enter the first folder then go to modules. Go to Dpram. Open up any of those files in notepad. You should see written non-compiled code right? That is fine now go back to the module folders and go to S3cbc. Now open up s3cbc_module.o. Does that look like non-compiled code? No it doesn't. It's either already compiled or encrypted. That's what I mean

Quick question, does that mean any custom rom that is release will be based off the official rom they release which has Touchwiz backed in? If so, does that rule out a plain vanilla android rom for this device? Thanks for your help and appreciate the knowledge.

No it doesn't rule out plain vanilla android rom. Yes they will all be based on Samsung but rom makers can take out all the touchwiz garbage and throw in another launcher like adw or Launcherpro.

That's what I wanted to hear. Thanks for the help. Now if I only could decide if I should keep the Nexus One or purchase this phone..... Decisions, Decisions.

what are talking about .o files and unix compiled modules same on all versions of unix. o stands for object module.

So they can easily be decompiled? If it's source code why is it already compiled?

dont go too deep into specific things that we may not even need (we are not coders here) but the source code for basic hardware that we need to get things going are already there.. things like camera, wlan, etc. btw, do u know what s3cbc is for?

What about s3clcd? Here is a little copy and paste of some of the garble that was in the compiled file
screen width=%d height=%d va=0x%x pa=0x%x
I would go out on a limb and say those are video drivers. The one's that have been encrypted on all other samsung phones.
Also in s3cbc there is some code at the bottom
PVRSRV_PIXEL_FORMAT_YUY2 PVRSRV_ERROR_FIFO_SPACE char ui32ByteStride psDevInfo PVRSRV_PIXEL_FORMAT_PAL1 PVRSRV_PIXEL_FORMAT_PAL2 pfnOpenBCDevic
If you don't know the Galaxy's gpu is PowerVR SGX540 and YUY2 is a colol format for video screens
http://www.fourcc.org/yuv.php#YUY2 and Pal is of course a European video standard.

they are not encrypted, they are object codes in machine language for arm.. and why we need that again for custom roms?

Wanted to test modaco ROM but they are not free.. Any kind souls upload and share ?

well feedback on the R1 rom its clean and smooth, worked even better when i did the stall tweak posted here

How much free ram have you got? Considering flashing and rooting, but not sure if it's worth it right now. Meh 10£ isn't that much think I'm gonna give it a try.
EDIT: Just flashed, but now I don't have root access(says access denied when I try to access the /data/data folder). Thought this included the rooted PDA file or do I have to flash that again with odin?
EDIT2: Scratch that I forgot to press the allow-button on my phone after sending the Super-user request..

[App] 2BOrange - Install any kernel (Voodoo, SpeedMode, Infusion...) without computer

____________________________________
2BOrange
____________________________________​
Hi everybody,
I have made a free application to install any kernel on your SGS very easily.
The idea is that there is a website where kernel are uploaded with a script and an application to:
- search
- download
- install it on your phone.
The application and the website are not limited to install kernell but I think it is a good way to try it.It can execute any script in the android shell.
So I have made some script for some kernel, there are so much that I have not the time to make one for each of them.
To make a script is very easy, I have attached an example of one I have uploaded on the website. If you need to attach a file, put it in a zip and upload both (the script and the zip) through the upload form on the website,
The address of the website is:
http://www.2borange.com/
A general thread on XDA (not dedicated to kernel on SGS) about the application:
http://forum.xda-developers.com/showthread.php?p=14875954#post14875954
You need to create an account to upload but it is not mandatory to just search, download and install a kernel.
Please keep me informed if everything work or not. I have only test it on my phone.
For the author of the kernels: I am sorry to have not yet informed you of the sharing of your great work, I will do it for sure when I will have done enough test to offer you an interesting way to share your work.
For the user: if you have time, don't hesitate to upload some scripts, it is free and easy to do...
Thank you for everything,
Michael
LIST OF KERNEL AVAILABLE AS OF JUNE, 27:
- Galaxian
- Infusion Kernel Faster Fusion Reaction
- Semaphore Kernel JVH - JVP
- SpeedMod Gingerbread
- TalonDEV
- TEGRAK lagfix- Voodoo kernel installer
- Voodoo kernel JVP
Don't hesitate to upload some new firmware. A model of script is provided below as attachment

This allows you to actually find a kernel, download it and flash it as well. The Kernel Flasher is just for kernels already on your sd card.

Thank you for your message.
I did not know about this application. I have read the description and I can tell you the purpose of mine is totally different.
I have understood that Nedar application is to install a Kernel that you have already downloaded and copy on your SDCARD.
The purpose of my application is to download automatically a script and a zip file, and execute the script.
So there are 2 main differences between these two applications:
- my application get files you need directly from the cloud (Internet), so it is like a deposit of files
- my application is not limited to kernel installation, it is just a usefull example to show people how it works, but it can do more, really lot more tasks.
However, because the application of Nedar is dedicated to one particular task, it has option I have not yet implemented in mine. By example, I have not yet construct a script to backup the kernel in an update.zip file, which could be very usefull.
So they are really very different. I hope I will be able to construct more script, but may be the biggest difference with any dedicated application is that anyone can participate to my project without any knowledge in Java programation.
You just have to know a little bit about shell to be able to share your work with others.
THAT IS THE REAL PURPOSE OF THIS APPLICATION : SHARING!

Amazing concept!
Thumbs up for the foresight for such a nice project. If enough effort is put I can see in next couple of months, the whole, ROM, Kernel, Modem flashing automated.
Right from finding the correct software till installing them and may be some debugging and fault finding as well!
Will definitely donate in case the project takes off the way it should!
Great work Snoopy!

Loving the concept of this!
As omzworld was saying, if this grew into a script that could automatically install your ROM/kernel/modem etc. that would be awesome, especially for people who are new to flashing.
Now, here's another suggestion that may or may not have been thought about already..
Is there any way to make the app look at your phone and use that as a basis for roms, kernels etc. ? If that was possible, anyone and everyone would be using your app to flash because they would know that bricking their phones would be almost impossible.

Thank you for your interest.
The thing I need now is not money, donation,etc... but report of test and ideas of improvment.
By the way, I only have a samsung phone, and I am wondering if there are possibilities to install kernel in other phone only by using the shell, have you an idea ?
Second question: have you an idea how to proceed to install an entire ROM through the shell ? I suppose the phone has to be rebooted before installation begin and lauche in a recovery mode, but how to make it automatic like in ROM Manager?
Thank you for your help!

[wip][rom][aosp] ns2

Change of plans, hopefully with the help of anyone who is willing I'd like to compile an aosp build for the Sprint GS2 from source instead of trying to hack a port together, as suggested in this thread and other places, it just feels like it will be a lot more of a fruitful experience for all involved and have a better end result.
(a big thank you to everyone who so far have been super encouraging and friendly with noob questions, it's much appreciated!, I hope that if you wanted to help with the port you'll help with this build as well!)
This is a WIP. Starting out with Samsung's open source platform and kernel instructions on how to build from aosp and I'll take it from there.
I've setup some repos to get this all started in one place:
Samsung SPH-D710 platform source - https://github.com/thefredelement/sph-d710_platform_source
Samsung SPH-D710 kernel source - https://github.com/thefredelement/sph-d710_kernel_source
Team Hacksburg kernel source - https://github.com/thefredelement/android_kernel_samsung_c1spr
Stock kernel initramfs (thanks buddy323!) - https://github.com/thefredelement/stock-initramfs-eg30-epic-4g-touch
https://github.com/thefredelement/Samsung-Galaxy-S2-Sprint-Epic-4G-Touch-AOSP-Build - will be where the build will live after I push over Samsung's platform make and upload it!
--- old stuff that will make your head spin ---
If anyone wants to continue working on this, feel free.
This is my attempt to get get a pure aosp build of android 2.3.5 for the Sprint Galaxy S2. I've never done anything like this before and it's mostly hacked together pieces of two different ROMs. I guess you can call this a "learning" experience.
THIS ROM JUST BOOTS AND NOTHING ELSE REALLY WORKS, THIS IS A WORK IN PROGRESS AND I POSTED IT HERE TO SEE IF ANYONE CAN HELP, THIS IS NOT A DAILY DRIVER, NOT EVEN CLOSE.
THIS HAS ONLY BEEN RUN ON MY PHONE, EVERYTHING IS FINE ON MY PHONE AND I CAN RESTORE A NANDROID BACK TO STOCK AND EVERYTHING STILL WORKS FINE BUT I MAKE NO GUARANTEES FOR YOUR PHONE. IF YOU DO NOT KNOW WHAT YOU'RE DOING I WOULD STOP READING NOW
This rom is based on AdamG's devnull-test aosp rom for the Euro Galaxy S2. (post: http://forum.xda-developers.com/showthread.php?t=1183063)
Credit must be given to AdamG for his rom in the first place, bubby323 for his help on IRC and kpkimmel at ACS for the Gerbal V1 beta ROM (post: http://www.forums.acsyndicate.net/showthread.php/2734-ROM-Gerbal-v1-beta-ROM) which I used for guidance for the build.prop and updater script.
I am not trying to steal anyone's work or take credit for anything, I really just want a pure AOSP rom for the Sprint GS2 and would love anyone's help as far as guidance, code, a guide I haven't found, anything would be great, thanks.
Known bugs:
- No radios
- No Wifi
- When wifi is on (or trying to turn on) the screen turns on/off as if a process is restarting
- Orientation sensor is out of whack (disable auto rotate so it doesn't drive you crazy)
- Home button & search button do not work
- Something FCs real fast on first boot but android setup starts
- Distortion on the touch screen occasionally
Known positives:
- No real FCs
- I added the Nexus S boot animation
- Calculator, gallery, etc. all work fine
What I've done so far:
Based on buddy323's advice in IRC, I've brought over vendor, firmware, wifi, vold, egl and hw from the Gerbal v1 rom to the devnull rom.
I used the wipe partition section of the Gerbal update script and then the symlinks/permissions from the devnull script (I removed the kernel installation as this rom doesn't come with a kernel). My approach has been to go through as much as I can on devnull and change out anything that's platform specific to the sph-d710.
I'm sure there's a bunch of noob happening in this rom and I'd appreciate it if you can call me out on it and tell me where to look to make it right.
Installation:
Install via clockworkmod, this will wipe /system /data so I'd erase your user data before flashing.
I've been booting this with the stock kernel.
Link: you don't want this...

Reserved for changelog, when hopefully it gets that far

Awesome to see a project like this, good luck in the port!

You are under no obligation to install anything posted on XDA. If it doesn't work, report. If you don't like it, don't use it. Help, don't hinder. If you have nothing to contribute, then sit down, shut up and wait for someone to do it and allow you to participate. It's that simple folks.
Now keep this on topic or infractions and/or mandatory vacations will be handed out.

I would highly recommend you get to grips with the aosp source and learn to build them for the device instead of cobbling a mix of aosp and stock Samsung roms together. You will also need an aosp compatible kernel and stock kernel is not. There is a list of patches to the aosp kernel in the SGS2 section and on team hacksung's github. Good luck.

THIS ROM JUST BOOTS AND NOTHING ELSE REALLY WORKS, THIS IS A WORK IN PROGRESS AND I POSTED IT HERE TO SEE IF ANYONE CAN HELP, THIS IS NOT A DAILY DRIVER, NOT EVEN CLOSE.
THIS HAS ONLY BEEN RUN ON MY PHONE, EVERYTHING IS FINE ON MY PHONE AND I CAN RESTORE A NANDROID BACK TO STOCK AND EVERYTHING STILL WORKS FINE BUT I MAKE NO GUARANTEES FOR YOUR PHONE. IF YOU DO NOT KNOW WHAT YOU'RE DOING I WOULD STOP READING NOW
This rom is based on AdamG's devnull-test aosp rom for the Euro Galaxy S2. (post: http://forum.xda-developers.com/showthread.php?t=1183063)
Credit must be given to AdamG for his rom in the first place, bubby323 for his help on IRC and kpkimmel at ACS for the Gerbal V1 beta ROM (post: http://www.forums.acsyndicate.net/showthread.php/2734-ROM-Gerbal-v1-beta-ROM) which I used for guidance for the build.prop and updater script.
I am not trying to steal anyone's work or take credit for anything, I really just want a pure AOSP rom for the Sprint GS2 and would love anyone's help as far as guidance, code, a guide I haven't found, anything would be great, thanks.
Known bugs:
- No radios
- No Wifi
- When wifi is on (or trying to turn on) the screen turns on/off as if a process is restarting
- Orientation sensor is out of whack (disable auto rotate so it doesn't drive you crazy)
- Home button & search button do not work
- Something FCs real fast on first boot but android setup starts
- Distortion on the touch screen occasionally
Known positives:
- No real FCs
- I added the Nexus S boot animation
- Calculator, gallery, etc. all work fine
What I've done so far:
Based on buddy323's advice in IRC, I've brought over vendor, firmware, wifi, vold, egl and hw from the Gerbal v1 rom to the devnull rom.
I used the wipe partition section of the Gerbal update script and then the symlinks/permissions from the devnull script (I removed the kernel installation as this rom doesn't come with a kernel). My approach has been to go through as much as I can on devnull and change out anything that's platform specific to the sph-d710.
I'm sure there's a bunch of noob happening in this rom and I'd appreciate it if you can call me out on it and tell me where to look to make it right.
Installation:
Install via clockworkmod, this will wipe /system /data so I'd erase your user data before flashing.
I've been booting this with the stock kernel.

I would highly recommend you get to grips with the aosp source and learn to build them for the device instead of cobbling a mix of aosp and stock Samsung roms together. You will also need an aosp compatible kernel and stock kernel is not. There is a list of patches to the aosp kernel in the SGS2 section and on team hacksung's github. Good luck.

I recall rumor about samsung sending a GS2 to Cyanogen so that he could "get to work". Guess that never materialized - or they gave him something else to do once they hired him...
Sent from my SPH-D710 using xda premium

it was one of the cyanogen devs that got a galaxy2 & they have nightlies for the gs2 now.... It should not be hard to get it ported over
....
One of the devs on teamhacksung was asking for people with the phone to help with it ..he ask on twitter like the 16th so they are probably working on it....

FAQ (A work in progress)
Where can I download this awesome ROM?
http://code.google.com/p/jellytime/downloads/list
What's so awesome about this ROM?
http://code.google.com/p/jellytime/wiki/Changelog
Is a full wipe needed?
No, it is not required, but it is strongly recommended. If you choose to do a "dirty" flash, please do NOT post bug reports or issues you are having, as something from an earlier release might be causing the issue.
I flashed this awesome ROM but I don't have (insert Google app here) why?
Gapps were removed from the ROM back on Alpha 7. You simply have to download the gapps from HERE and flash via recovery.
Is Project Butter working on this ROM?
vsync was implemented in Beta 9 and triple buffering in Beta 10. So, yes, Project Butter in included.
I'm having an issue and want to report it but I don't know how.
First, check the Issue Tracker to see if someone else has reported the same issue. If no one has reported the issue then start a new issue and follow the provided template to describe your issue. Don't forget to attach your logcat.
I keep posting an issue to the Issue Tracker but it keeps getting deleted?
First, did you click the continue button on the page before the Issue Tracker? Yes? Are you sure you read that page and filed your report as explained on that page? No? Then there's your answer. Read the page that tells you how to properly submit a bug report and submit your issue properly. It will be marked as Invalid until it is properly filed after a day or two if is not filed correctly it will be deleted. For more information on how to file a log read below.
I keep reading about this "logcat" what is it and how do I make on?
"The Android logging system provides a mechanism for collecting and viewing system debug output. Logs from various applications and portions of the system are collected in a series of circular buffers, which then can be viewed and filtered."1 To learn more about logcats and how to create them please read both of these threads, they are very informative;
Adrynalyne's Guide
Lanternslight456's Guide
Is Jellytime better/faster then (insert your favorite ROM here)?
Its all a matter of opinion. You'll get 10 different answers from 10 different people. The reason for this is different people use their phones for different things, so what may be an awesome experience for one might be terrible and full of bugs for another. The best way to choose is to just flash Jellytime and find out for yourself.
How's battery life?
This is also a matter of opinion. Like the previous question you'll get 10 different answers from 10 different users. People use their phones for different things. The only true answer is to find out for yourself. If you are having battery issues however, there are a few things you can do. First, find out which apps are causing the most drain. Kill them and see if that helps. Second you can re-calibrate your battery (check THIS out). You can also read the post I made that has a few more suggestions HERE.
I can not flash this ROM why?
Ok, Jellytime is a ROM with a 3.0 based Kernel. For whatever reason (don't ask me why) but for some first time flashers the 3.0 based Kernel doesn't play nice. Have no fear, there is a "fix' for this. All you have to do is flash an up-to-date stock, sense based ROM. LIKE THIS ONE HERE. After you've flashed that you can flash whatever ROM with a 3.0 based Kernel to your hearts content.

The purpose of this thread is to help those of you who aren't sure of something and to help find answers. All credits go to randomblame and his team for all their hard work and dedication. This will hopefully keep the dev thread clear of clutter so they can work more efficiently. Feel free to ask questions pertaining to his rom!
Over time I will be building a FAQ section (based on the questions asked here) that will be added here, to the Project Page Wiki, and hopefully to the thread page. Please keep this thread clear from flaming, there are no stupid questions. I ask that you read all posts here, the OP found above, and the Project Page before posting. Thanks

Any flaming will not be tolerated and will be reported directly to the mod.

I think the most important question for new users to Jellytime is:
Q: Is project butter implemented in this rom? If not will it be implemented? If not why it won't be implemented?
Sent from my Desire HD using xda premium

Ignore

Q: Does using V6 Supercharger break anything when using this ROM? I'm on RC 5.1, while it doesn't seem that V6 improves anything (JellyTime is already super fast!), I'm not quite sure if it breaks anything
Q: Is it safe to remove the stock launcher, nova launcher, and the news and weather apps?
Thanks

Honestly, the best way to find out is to try it yourself. Nandroid your current ROM and install the other one. If you don't like it, just restore your backup. The differences between them are slight, and it comes down to personal preference.

Q: is there a faster way of getting screenshots? The only method I know for this rom is Power + Menu then choose screenshot. In sense roms I used to do Power + Home and a screenshot is taken right away. I also checked Settings > System > Hardware keys and there is no option for screenshots for custom actions

AFAIK holding the Power and VOL Down button at the same time and holding until the screenshot is taken is the other way without doing the menu option. It takes a bit of getting used to and the timing has to be pretty close or it'll just activate either the power menu or the volume will go down. I'm not aware of another method, but if anyone has any suggestions, all are welcome.

I'm sure there's probably a blog or thread on XDA somewhere for this, if so please just throw a link up, but I am curious about the differences in the CPU Governors that are available. Other than just trying them all to see how my DHD performs, it would be nice to know about the subtle differences that make one operate different from the other.

Is there any difference of users experiences dependant on which loader they use CWM or 4ext, eg. certain types of bugs, glitches associated with one or the other. I may try 4ext and see if it cures my occasional vertical rainbow screen [ which am still reading up on logcatting ]

A: well i moved from cwm to 4EXT and to tell You frankly, i just hope that 4EXT will support all android phones in the future!!! all though still on RC version it is just a pleasure working in, both the .apk and the recovery touch it self. Besides the touch function 4EXT also has a much better, wider interface, no need to do jump in and out of dirs, the dev has made it so that You can for example choose if You wanna wipe cache and dalvik in one instance, and in tools You find all kinds of different and helpful combinations. 4EXT has everything + allot more then cwm. And not forgetting the .apk, from in there You can plan how You wanna for example wipe, install and so on, and by just pressing the button, it reboots and does the task You planed, reboots and that is that. Especially now when all the time wiping and re installing, it was tiresome and time consuming with cwm, but now....it is just quickly dun by the 4EXT.apk, just using half the time of what i used on cwm. As they say.....4EXT is the future recovery and i have been hearing that the dev. is also experimenting implementing rooting features, so You just install the .apk and it then roots a stock phone......that would just be great!!!

It also seems that people are having fewer issues with things not showing up using 4ext rather than CWM, or maybe that was ROM manager. But you are right - 4ext works wonders in multitasking like flashing wipe rom, rom, fix, fix, gapps, TiBu all at once.
