Flashing Galaxy S kernel from update.zip : template update.zip

NEWS :
Koush's bmlunlock (a simple IOCTL send to the bml device) is just out and can replace redbend_ua !
http://github.com/CyanogenMod/android_device_samsung_bmlunlock
Hey
Is Flashing from update.zip the new trend ?
'Don't know but here is how you can do it quite easily using this template.
If you target a GT-I9000 on Eclair, you'll need to customize one thing :
In build-update-zip.sh, set DROID_HOME to the source code path for your local Android repository.
If you target another Galaxy S phone or another version of Android, you'll need to adjust ro.hardware and ro.build.id properties accordingly.
This template is done for Linux/Unixes/OSX.
If Linux cost too much for you or your employer, please contribute by sending a .bat equivalent to the .sh
Of course, you also need to put a valid zImage to replace the template's empty zImage
Feel free to adjust to your needs. License is WTFPL
Note : requirement are Java and Android source repo, already build.

Looks awesome!
I have a question though... why do you need to flash the kernel in an update.zip at boot?
As far as I know, the system will read the kernel at boot up time and load it into ram. It won't access the on-disk file again until the next boot. If that is true, then flashing while running should be 100% safe, right?

RyanZA it's an update.zip, not a ramdisk.
The point is getting an easy flashing method, requiring no computer.
And you don't even need to root your phone !

curio, as i see this script is quite simple, so dont u think this all could actually be done on the phone directly? i mean if people cant afford a linux machine...
edit:
sorry for major dumbness, but do you think this could also somehow be used to reflash a nandroid backup?

I don't think the signing tool works on android -- maybe it does? Anyway editing scripts on a phone seems a bit silly!

Nope actually this is not dumb at all
Yes the flashing part run in updater-script can be started manually.
In the script :
Code:
"redbend_ua", "restore", "zImage", "/dev/block/bml7"
The update.zip presented here mainly targets custom kernel creators in order to give them another way to distribute their work.
This is a working example of how to use redbend_ua programmatically, hopefully it may help new ideas coming. redbend_ua usage is not limited at all to kernel flashing.
PS : you can use this template with windows as well, you'll just need to translate the ulta-basic .sh to a .bat script, or do the signing part manually.

quick question, the build-update-zip.sh is not a must if i only want to flash zImage, rite?
looks like that, I need to modify updater-script (if needed), as well as putting a zImage into ur zip file, and finally remove the build-update-zip.sh from ur zip attached
then, ur zip file can be used for flashing
is it correct?
thx

So this will let people flash any rom from an update.zip (once the ROM makers take this into account) via RomManager without ever having to use Odin to get off stock?
Awesome!

Thanks for the update script curio! this looks great.
One quick question - ive noticed several update.zip scripts for the galaxy S
have update-binary included.
Does anyone know what that does?? where did you get yours?
ive had success in using update.zips without that file at all.
Could anyone post information on what that binary is/does?

Thats for the updater-script i believe. In most cases, theres a update-script in the zip's as well and the recovery picks that up in which case it doesn't need the binary and hence works.

Okay !

When you run ./build-update-zip.sh,
- it produce a temp zip file containing appropriate files in it.
- then there'is the signature part, building another .zip, ready to be used.
- this "final" update.zip is put in the same current directory and you can use it as it is.
No further complication

Yes, to flash a complete ROM (several partitions) one more thing is needed.
On command line, redbend_ua accept only one command.
In order to run several commands successively (ie flash multiple partition like Odin does), you'll need to write them in a file.
The file /cache/ota/command should do the trick, but it's untested right now.
There may be other method to prevent rebooting after flashing (hacking the redbend_ua binary, finding the appropriate command line option or removing the reboot command temporary)

Right, many update.zip done today are made without knowing anything about how it really works
I studied a bit before creating mine, here is a walk-through this fairly undocumented process :
- recovery mounts /sdcard/
- recovery search for a default file named : META-INF/com/google/android/update-binary in the zip and runs it : see the source in bootable/recovery/install.c
- update-binary is actually updater in sources
- updater looks into the zip file to the script file named updater-script, update-script is obsolete
- updater then runs the commands listed in updater-script : here is the list of commands.
- then reboot
The only documentation I know for this command is the recovery/updater/install.c file itself

ok,thx
but one more thing i want to know is, u said the path must be changed to the android repo, so do u mean the source code for the kernel like linux-xxx-2.xxx dir?
Thx

@ykk_five
Content of build-update-zip.sh v1 :
Code:
#!/bin/sh
DROID_HOME="/home/curio/dev/mydroid"
zip -r /tmp/update.zip META-INF/ redbend_ua zImage
java -jar \
$DROID_HOME/out/host/linux-x86/framework/signapk.jar \
$DROID_HOME/build/target/product/security/testkey.x509.pem \
$DROID_HOME/build/target/product/security/testkey.pk8 \
/tmp/update.zip update.zip
rm /tmp/update.zip
adb push update.zip /sdcard/
DROID_HOME="/home/curio/dev/mydroid" : you set here the directory of your Android AOSP directory.
See : http://source.android.com/source/download.html
Create an empty directory to hold your working files:
$ mkdir mydroid
$ cd mydroid
Run "repo init" to bring down the latest version of Repo with all its most recent bug fixes. You must specify a URL for the manifest:
$ repo init -u git://android.git.kernel.org/platform/manifest.git
* If you would like to check out a branch other than "master", specify it with -b, like:
$ repo init -u git://android.git.kernel.org/platform/manifest.git -b cupcake
Click to expand...
Click to collapse
This is this mydroid directory
The one that contains Android git source home directory, and compiled files in the out/ subdir

many thx for ur detailed explanation, supercurio!

Thanks curio,
very helpful explanation!

Thanks supercurio for the template!
However, there is no need to spend many hours (depending on hardware and bandwidth) pulling down 100s of megabytes of source and compiling it all if all you want is to sign an update.zip with test keys (if you already have the zImage)!
Just google around for "signapk.jar test keys" and you will get there.
BTW: I know that koush, leshak and wesgamer have Samsung Galaxy S trees up at Github but are they fully merged with AOSP yet?
I'm planning to go build my own kernel for this beast to try to solve the mono FM radio mystery, but last time I checked around it was said that the SGS tree required the use of a custom toolchain to get it to work at all.
Any comments on this?

Hey miki4242 !
Good to know that signapk.jar doesn't require hundred of megs of dependencies
About toolchain, you can use the one indicated by Samsung (CodeSourcery) but you'll face the big and ugly WakeLag.
I recommend you crosstool-ng or buildroot to build toolchains, with gcc 4.3.x march=arm mcpu=cortex-a8 mtune=cortex-a8 (no 4.4.x with march=armv7-v)
The building tutorial will be a part of the documentation I'll publish with my lagfix opensource release
Right now these info are too hard to find.
PS : I send you a mail with attached .config for ct-ng !

Sorry for my ignorance, but does this mean someone can package Froyo in an update.zip and we could update it directly on our phone without needing Samsung Kies or Odin?

@supercurio:
Thanks for this well working template.
In updater-script:
Code:
line 17: package_extract_dir("zImage", "zImage");
should be
Code:
package_extract_file("zImage", "zImage");
But it did work with package_extract_dir, for some reason, too.
Btw, could you send me the config for ct-ng ?
I'm also struggling with this wakelag.

[KITCHEN] Minimal kernel building VM with scripts

I added some convenience scripts to the config. Read the new tutorial here
The old one still works:
I put together a small virtualbox vm with a very minimal debian config with which I was able to compile a working kernel. This is for all the people who are running Windows, and want to try modifying kernels/initramfs's. As this is a minimal config there are some drawbacks (like it doesn't have a graphical interface), but you can always install additional packages, if you want to.
The VM includes: debian, build essentials, git, vb guest additions, mc, vim and codesourcery 2010q1 gnu-eabi. (it's larger than the simple eabi version, but can be used to compile non-kernel applications too)
First of all I hate both SunOracle VirtualBox and debian, but VB is free, and debian is lean, so they'll do the job.
To get the image running do the following:
First download and install VirtualBox
Next download the VM image: http://android.sztupy.hu/dl/KernelCompilerVM-1.1.7z and extract it. (it's a large download. If you can please put it up a mirror)
Mirrors: (thanks to the people mirroring it)
- http://www.multiupload.com/THJV19BJ9X
- http://bote.ro/sztupy/KernelCompilerVM-1.1.7z
After this run virtualbox, and import this VM.
Run the VM. The username/passwords are: root/root and kernel/kernel. Login with kernel. (you can always switch to root using sudo)
Next choose what kernel/initramfs you want to compile.
Here are some links to kernels:
The original sources can be found at supercurio's git:
Code:
git://github.com/project-voodoo/linux_gt-i9000.git
froyo-samsung branch
The kernel of the voodoo project can be found at the same place:
Code:
git://github.com/project-voodoo/linux_gt-i9000.git
froyo-voodoo branch
The ULTK kernel can be found at my account:
Code:
git://github.com/sztupy/universal_lagfix_kernel.git
Here are some links to initramfs files:
The original froyo initramfs can be found at supercurio's git page:
Code:
http://github.com/project-voodoo/samsung_ramdisks.git
afaik the voodoo initramfs is build using scripts from these images, so you have to apply them.
The ULTK initramfs can be found here:
Code:
git://github.com/sztupy/universal_lagfix_kernel_initramfs.git
For the rest of the tutorial I'll be showing how to compile ULTK:
First get the kernel sources using git:
Code:
git clone git://github.com/sztupy/universal_lagfix_kernel.git kernel
Unfortunately no copy-paste function is available, so you have to write this manually...
Next get the initramfs using git:
Code:
git clone git://github.com/sztupy/universal_lagfix_kernel_initramfs.git initramfs
If everything goes well you'll have two directoryes, called kernel and initramfs. Next we have to modify some values in the kernel configs.
Nano, mcedit and vim are installed, use the one that suits you best. (mcedit is the most user friendly)
Switch to the kernel directory and edit the Makefile there:
Code:
cd kernel
nano Makefile
Find the row that says
Code:
CROSS_COMPILE ?= some value
Replace it to
Code:
CROSS_COMPILE ?= /home/kernel/arm-2010q1/bin/arm-none-linux-gnueabi-
(if using nano make sure it won't add a line break into the row)
Next load the default config:
Code:
make aries_eur_defconfig
And edit it:
Code:
nano .config
We have to supply the directory of the initramfs. Search for the line:
Code:
CONFIG_INITRAMFS_SOURCE=some value
and replace it to
Code:
CONFIG_INITRAMFS_SOURCE=/home/kernel/initramfs/out
(this is for the ULTK. For voodoo the initramfs locations are "froyo-xxjp6" and "froyo-xxjpm" instead of "out")
if you've managed to do that too, let's compile the kernel:
Code:
make
If everything goes fine after a while you will have your shiny new kernel. Now let's get it to your computer, so it can be flashed:
First, you have to create a shared folder in VirtualBox. Simply create a directory somewhere on your computer, and add it as a shared folder in virtualbox. The name of the shared folder should be simple, for example "shr".
Next, you have to mount that directory inside the VM. To do this enter:
Code:
sudo mount -t vboxsf shr ~/share
After it has been mounted you can copy the fresh kernel to your host OS:
Code:
cp arch/arm/boot/zImage ~/share
If everything goes well you have a zImage ready at the folder you've just shared. TAR it, fire up odin, and flash.
---------------------------------
Now that you've succesfully compiled a working kernel try to modify it. You can use "make menuconfig" in the kernel directory to switch some kernel functions (like filesystem supports) on and off. You can edit .config by hand to add or remove some configuration values. And you can edit the files in the initramfs directory. After modifications you only have to enter "make" in the kernel directory to get your kernel inside the "arch/arm/boot/zImage" dir ready.
You can also copy files from your host OS, to the guest OS, by putting the file inside the shared folder and copying it:
Code:
cp ~/share/thefile ~/initramfs/copyithere
Hope this guide was useful.

Impressive, thanks. Even a noob like me can try this.

Oh god, not only a talented developer, but a community helper!
STICKY!!
Gonna try it laters <3

oh yea, nice!

high time you start compiling kernels

tnx
its very usefull

Magnificent!
I just came to take a quick look, but the thread deserves a closer one.
Thank you for sharing knowledge.

Worthy of a sticky.
Hopefully this will solve all those "I want this in a kernel but not that" scenarios.

This is VERY nice for the devs.. but.. i think this will make this forum spammed with 69 diff kernels with just minor changes.. as with the roms

Its better to let other people brick their phone than you brick your own
Just kidding! I for one will try and compile different versions with different lag-schemes to find the fastest combination. Including /system with fastest reading. I think I will add a benchmark to the recovery menu directly. Benchmarking each mount for read and for write speeds. Maybe I can use backup/restore code and just time it without writing (cp to null). Lets get to work
Thanks sztupy!

Fluxbox/Openbox. However I don't see the need for one, if you're running the machine just for compiling.
Also, shouldn't gpm+guest additions solve the copy-paste problem?
E: Apparently not. Meh, stupid virtualbox.. sshd+putty then!

Awesome! Thanks for this sztupy! The more people we can get involved in this stuff, the better the end result will be. Always!

actullay i was looking for something light and minimal (with GUI, or at least something like PCman FM and gedit or kedit, im not good with emac, vi ) to play and compile AOSP, for now i do this with Kubuntu dual boot on my laptop. if i put a litghweight desktop on top of szytup's image and use it with VB, that would be great.

I'd use a shared folder+IDE/editor/whatever on windows. But that's just because I have so awful experiences about X in VMs, things might be better nowadays

Thanks a lot sztupy, will try it now. Sunday is enough time for testing
Each morning i have a look at XDA and you have brought out a new very helpfully posting, kernel, rom or else!
So let me ask you one question: when do YOU sleep?

The advantage of using X is that afaik guest additions has copy-paste support, that would make modifying easier.
I also plan on making some simple scripts inside the default home directory one can run to communicate with the shared folder. After that we could provide simple scripts that you only have to put inside the shared folder, which will download, modify and run the compilation.

[SCRIPT] Kernel building script Team BlueRidge

I have written a script that should allow anyone with basic knowledge to build a kernel.
This script will walk you threw everything neccessary, and is centered toward the wildfire s. It is universal however.
This is the first release and there are improvements on the way, if there are any features you need or wannt let me know and i willl look into them.
PLEASE DO NOT COPY
V1
Down updated now
V2
https://github.com/simonsimons34/kernel-building-script
This is where it will be updated
if you find issues, go ahead and report it on the issue tracker. If it gets annoying i will just ignore it though so use wisely...
If you find this useful please hit thanks
for now follow please follow the cm wiki.
you need the proper packages
then the ndk
then you need to link the gcc files and /bin content files in the toolchain of ndk to /bin symbolically (sudo ln -s (drag in files))
then you should chmod the entire contents
then go to the kernel source directory
then run make mrproper
now pull a config from your phone (adb pull proc/config.gz ~/config.gz)
then take that gz and extract the config move to the kernel source and rename with a . in front.
Now, do make menuconfig in a terminal that is cd'd to that kernel source
now do this make ARCH=arm CROSS_COMPILE=/path/to/ndk/toolchain/bin/arm-androideabi-

[KERNEL][HOWTO] E4GT Community Kernel - Updated: 2/26/2012

See second post for changes.
My phone has a nicely corrupted bit of memory right where my data partition is supposed to be so I can't really test any changes on kernels at the moment. Once my replacement gets here, I have quite a few changes to test and then push. Hopefully others are haveing some good luck with there own kernels.
This first post is going to look a little rough until I take the time to pretty it up, but I figured I would get at least this up and let it evolve from there. I know I gloss over some stuff(what the hell is a defconfig, you ask?) but I will flesh this out over the next few days (Years, really. Damn contracts)
Project Goals:
Provide a standard base and scripts for building kernels for the E4GT.
Attempt to provide reasonable documentation of the build/debug/pray-for-success process so that those that wish to learn, can.
What is included in the current base:
Completely Stock EL29 Kernel
initramfs for Samsung based ROMs with ClockworkMod and root
Codesourcery 2009q3-68 toolchain
Base for creating a ClockworkMod flashable kernel
Build script to tie it all together
Getting started:
Install Ubuntu or Linux distro of your choice. This guide is written for Ubuntu as that seems to be the most common choice for Android Development.
Install required packages
Install Oracle Java JDK, setup the Android SDK, and install other required packages from terminal.
For 32-bit installs:
Code:
sudo apt-get install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
and 64-bit:
Code:
sudo apt-get install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev ia32-libs lib32z1-dev lib32ncurses5-dev gcc-multilib g++-multilib
Download base
In terminal emulator, go to the directory you'd like to download to and type:
Code:
git clone git://github.com/SweetwaterBurns/xda-base.git
Pick a branch. Currently available are powersave, performance and master(all identical until things start moving forward a bit, I intend to keep master updated with the latest stock kernal) and select it with
Code:
git checkout powersaveorwhateverbranchnameyouactuallywantipromisetonotactuallymakeabranchthatisquitethisridiculousmaybe
Profit!
In a terminal emulator, change to the xda-base directory and type
Code:
./build.sh
and wait... congratulations you've just compiled your own kernel.
But wait there's more The build script will let you build with more then just the included source and toolchains. The basic format is ./build.sh kernel initramfs defconfig toolchain. All you have to do is copy the files into the appropriate directories and you're good to go.
So, if for example you wanted to build an EK02 kernel using Team Rogue's initramfs, the Linaro 11.12 toolchain and your perfect_defconfig, you would copy the source to xda-base/kernels/EK02, place the initramfs in xda-base/initramfs/rogue, and the toolchain to xda-base/toolchain/linaro. Place perfect_defconfig into EK02/arch/arm/configs/ and type the following command from the xda-base directory:
Code:
./build.sh EK02 rogue perfect linaro
The flashable zip is saved in xda-base using the defconfig, date and time in order to keep your files somewhat organized. I'm going to add kernel version to that in my next update, as well.
The base is essentially a snapshot of where we are at this stage of development and hopefully the community can help us improve it. Everything seems to be working, but if you come across any bugs/fixes, please share.
If you'd like you propose any changes, submit a request via git and I'll add them to the repo if it makes sense.
I'm typing a lot of this up from memory so please forgive any mistakes or omissions. If you find any let me know and I will update ASAP. If it seems confusing, let me know where clarification is needed. My goal is to figure this stuff out and help others while doing it. Any criticism will be taken constructively and I hope this helps spawn few more talented devs for the E4GT.

Known Issues:
Don't choose reboot to recovery after flashing Blazer 3.9(possibly others) I was able to reproduce this on Team Rogue's el29 repack as well.
I didn't realize that git doesn't push empty directories which caused issues with modules not being copied in to the initramfs. I'm going to fix by adding a check to create the files if necessary into the build script. in the meantime, just create initramfs/initramfsroot/lib/modules and remember to make sure that the directories are in any alternate recoveries you use.
Changelog:
2/26/2012
Added a quick howto on working with git and submitting pull requests to post #4. As soon as new phone gets here, I'll be uploading some new changes to performance.
2/13/2012
All right.
There are now branches for powersave, performance, and stock. Once you have cloned the repo you can select which one to use by typing
Code:
git checkout powersave
or whatever. The only difference between the repos at the moment is that I renamed the kernel source directory to match the branch name and edited the build.sh to build the respective variants by default. If anyone has any requests for other branches, let me know.
I also added a check to the build.sh to ensure that there is a lib/module directory in the initramfs that modules can be copied into.

Proposals:
I'm thinking about setting up a few different branches for the kernels. One for the latest clean stock kernel, one for those who would like to focus on performance, one for those that are more worried about battery, and possibly a bleeding edge kitchen sink kernel. More than I can handle myself, honestly, but if those of you that are already making modifications start pushing it should be doable.

How to use git and submit pull requests on github.
If you haven't already, create an account on github Navigate to the xda-base repo and click fork in the upper right.
In a terminal emulator, go to the directory you would like to store your source in and clone your new fork with
Code:
git clone [email protected]:USERNAME/xda-base.git
git remote add upstream git://github.com/SweetwaterBurns/xda-base.git
The second part adds the original repository as an upstream source so that you can keep your code base updated with any changes.
Probably one of the most useful tools available is branches, essentially if you would like to add or change a feature, you would create a branch for working on it. Having it contained with in it's own branch is good for several reasons. It makes it easier to find any changes that you made without pulling in any extra cruft from other things you might be working on and helps prevent any conflicts that might arrise from working on too many things at once with in the same source tree.
Branches can be created locally with
git branch BRANCHNAME
For example, if you wanted to branch the performance kernel you would
Code:
git checkout performance
git branch performance-FEATURE
git checkout performance-FEATURE
This creates a local branch that you can work with, if you would like to push it to github for others to work on or to use it to submit a pull request:
Code:
git push origin BRANCHNAME
Branches can be deleted locally and remotely with
Code:
git branch -d BRANCHNAME
git push origin :BRANCHNAME
Make any changes you'd like and tell git which files you've changed with
Code:
git add CHANGED FILES HERE
Then commit those changes with
Code:
git commit -m 'Description of changes here'
If you would like to submit a pull request upstream, first fetch upstream and merge it with your work to make sure that any changes that have already been pulled don't conflict with your changes and that it can be merged cleanly. Use whatever branch you used as your base for the merge, i.e. for changes you'd like to submit to the performance branch
Code:
git fetch upstream
git merge upstream/performance
This will spit out any conflicts that need fixed and you can repeat the process until it merges clean.
Push your branch to github and navigate to it's page. Github has a pretty good write-up on sending pull requests and the process is really pretty simple.
Any questions, ask away.Any errors, let me know.
To Do:
Show how to add a remote repository and use it to port features using 'git cherry-pick' or whatever.

and one more for whatever else we might need.

Good job! Looking forward to see what comes from this. Good to see a forum to learn from.

Well, I guess my first request is how to add boot animation support to a kernel? Is it as simple as adding the lines to the init.rc?

I can either add a line to the init.rc to soft link bootanimation.zip to sanim.zip or put it in the CWM update script. I'm leaning towards the update script as it really should only need to be done once.
Also, be prepared for issues flashing Blazer 3.9 the flash didn't quite take when I tried it this morning.

SO, there's a great thread in the developer's section: [KERNEL][HOWTO] E4GT Community Kernel - 2/12/2012
Really nice job. I've built & flashed the kernel. BUT, the WIFI won't turn on, and 3G data won't flow, even though it shows 3G connectivity (Sprint Epic 4G Touch, rooted to L29 with CWM earlier...). Anybody have a clue what I may have messed up? Just ran the straight defaults, figuring that would get me into the least amount of trouble. One diagnostic: there was a number of segment mismatch warnings - I've had those in embedded kernels in the past, and they're usually not meaningful. Maybe this time is different?

He can PM me and we can try to go over his settings to see what's wrong.

his reply
"Okay, found the problem, and I feel very slightly less stupid. Watching the build go by, I noticed diagnostics that the script was unable to copy the driver modules to the temporary initramfs lib/modules directory. In reading the script, I saw that the build.sh was wiping the temporary initramfs lib directory. SO I added a couple of lines to the build.sh script (the middle two lines are mine):
#Find all compiled modules and copy them for the final build
mkdir $INITRAMFS_TMP/lib
mkdir $INITRAMFS_TMP/lib/modules
find -name '*.ko' -exec cp -av {} $INITRAMFS_TMP/lib/modules/ \;
Which allows the script to copy the loadable modules, and POOF! Now I've got WIFI and such...
The script in the git repository should either get modified, or some additional tests on running the script implemented. One of my thoughts was that having dash as the shell script might be causing problems (I've had that before) - but that wasn't the problem.

Its all about the desire to learn. Some start with theming. Then there are those that make ROMs but don't necessarily know how to make a kernel. There's a lot to learn. Its all about having the will and time to do it. The more development the better imo

Yup, just compiled my first fully working kernel yesterday.
Already overclocked it to 1.6 with extra added cpu steps for lower clock speeds...
Just tried adding and defaulting bfq scheduler but the jf4s module wouldn't compile after wards for some reason..
Ill figure it out eventually.. Right now im adding smartass / v2 see if it works...
EDIT: That didn't work either hmmmmm... Anyone know why when you edit the c1_rev5 config file the j4fs module doesn't compile?

[ROM][Source][Jan 11]CM7

To compile any of the KFire-Android roms please see the instructions in our build wiki.
Device History / Commit Log
This is a mostly stock cm7 build that I try to keep relatively updated for those who still want to use Gingerbread:
Changes from CM7 Stock:
Removed ROM Manager.
Removed CM Stats & Update Notifier.
Added GooManager and Goo.im compatible auto-updater script for incremental updates.
There may be some other differences I'm not remembering honestly it's been awhile since I updated the code.
Assert standard disclaimer.
Click to expand...
Click to collapse
Download the latest package from Goo.im either @ http://goo.im/devs/IngCr3at1on/Otter/cm7stockish
or
via GooManager itself under Browse Compatible Roms > IngCr3at1on.
(the md5sums are listed on the downloads page, if you are downloading via GooManager it checks the md5sums for you).
Make a backup in recovery.
If new to cm7: wipe data (factory reset) and system (found under mounts and storage) otherwise wipe cache (dalvik cache is on the cache so this is enough).
Install zip from sd card
Optional:
Download and install gapps (included optionally in GooManager).
Extra information:
It is highly recommended that you use an OpenRecoveryScript compatible recovery to make full use of GooManager (Cannibal Open Touch Recovery {see second post} or TWRP).
If you are coming from stock you will need to move all your books from /sdcard/Books/ to sdcard/kindle/ (please note some of these may need to be redownloaded).
There is some confusion regarding the entries "Phone Idle" and "Cell Standby" in the battery/usage stats. This is referring to the device idle and standby, it could just as easily say "Tablet Idle" and "Device Standby" but it wasn't considered in the original creation (this can be resolved w/ an overlay most likely but I have not researched it). Your device battery is not wasting away to some mysterious phone/cell service so sleep easy.
By default the lockscreen is disabled; to enable it simply go to 'settings' > 'cyanogenmod settings' > 'tablet tweaks' > uncheck disable lockscreen.
For some unknown reason (to me at least) the market is not properly loading after flashing gapps; to make it load go into 'settings' > 'accounts and sync' > add your google account. The market should appear after that.
You will likely want to install an app to supplement a back button; for this there are button savior and another (allows gestures) which I can't remember currently (someone post the name and I will update this lol).
I would also recommend VolumeControl for supplemented sound controls.

I've released the recovery under a new name; out of respect to Team Hydro and the original creator of the Dooderbutt image the release is at Cannibal Open Touch, the binary is also available directly on Goo Manager under 'dev/IngCr3at1on/Otter/CannibalOpenTouch/' or direct @ Goo.im (we will be creating a XDA thread for the next release).
-----
A word about kernels: to my extreme annoyment I have yet to get the wireless modules for the kernel to compile on my machine (currently I have given up on this effort, a single module is not worth the headaches) to that end the original JackpotClavin kernel is still included in the source (I do not have source to this and I believe it is the cause of at least some of the issues when running this rom) for the time being please flash an alternate kernel after installing the rom. I would eventually like to replace this kernel with a non-overclocked performance kernel (for OC you will have to install it separate). If someone has a kernel which they would like to see added to the source (this includes Hashcode or IntersectRaven) please fork my device repo and open a pull request with the replacement zImage and modules (include a link to source in your pull request please) I will test it and barring errors merge it.

Is there anything new?

I appreciate this. thanks.with it being source, u should leave it as is imo, kernals are out there and usually get cooked into custom roms, which is what I've been interested in learnong lately. so again, thanks

I agree that most custom roms will have custom kernels and that's part of why I don't want to include an OC kernel; as it is the stock kernel that's included has some issues though and I'd like to replace it with something more stable (ideally a slightly optimized non-OC stock) similar to Hashcodes kernel. I have tried compiling Hashcodes kernel as a replacement (intent on making some small tweaks if I did) but as previous mentioned I keep hitting walls with the wifi module, it's very annoying.

Aye same issue though sadly; wall with wifi module (I suppose I could build the kernel than pull the wifi module from someone elses but that feels like cheating lol). At this point I'm so annoyed with the wifi module though compiling a kernel is one of the last things on my list, this is why I have requested that someone else do one and add it via pull request.
On that note pull requests on any of my repos are always welcome (anything to fix my half baked swiss cheese hackings)

after I curl repo, I get the info showing it was created. I than chmod it, than attempt to repo init and I get repo not installed. but when I check my files, its there. but when I call repo init it keeps saying file doesn't exist. its my first time really building in ubuntu, sorry

Could try. '. repo' personally I've never had Ubuntu require this for the repo command but most Linux commands do require the dot. If it works I'll update the OP and readme that info was in the old readme but for some reason I removed it.

Alright; just got off work had a chance to actually look. First of all let me say sorry. Entirely my fault (sort of) it's what I get for ripping the walk through from someone elses readme without confirming it...
use this instead
Code:
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod a+x ~/bin/repo
updating the OP now

that was the second thing I tried. first u gotta mkdir ~/bin than curl ~/bin/repo than chmod ~/bin/repo than mkdir /cm7 CD /cm7 but when I repo or. repo or. /repo I still get the error.

Yeah sorry, SOD issues are kernel related I believe; part of why I am wanting to replace that kernel. Try an alternate like intersect ravens or hashcodes kernel to see if it doesn't happen again.

I thought this ROM would've licked that pesky Status Bar Force Close issue. Netflix works perfectly though. 1 out of 2 ain't bad.
