Update (01-03-09)
v1.31 is out! This is a minor bugfix release to fix a few issues that had cropped up in v1.3.
The changes from v1.3 include:
Fixed the nandroid backup so that it works on sdcards with a raw fat32 filesystem (with no partition)
Added the telnetd binary from RC28
Fixed an issue with SuperUser where it was displaying the wrong processes in the su request popup
SuperUser should allow root to use su without displaying the popup (though there's not much point.. )
Added /system/modules and /system/xbin to fstab in normal and recovery mode
Minor fix for the update-script, so the progress bar acts more sanely
I have the usual RC30 and RC8 versions, and new for v1.3 is an ADP1 version.

These updates are installed the normal way. Save them to your sdcard named update.zip, boot into recovery mode (home + power), and then press alt+l and alt+s. If you are switch between versions, e.g. from RC30 to ADP1, then it's usually a good idea to perform a wipe. You can try booting up without a wipe, but if it doesn't boot, or you get strange errors once it boots up, go back into recovery and perform a wipe (alt+w)
Note: To install these updates, you need to have a recovery image that uses test keys. If any of the following are true, you most likely have a recovery image that uses test keys
- you have installed my modified recovery image in the past
- you have an ADP1
- you currently have one of my modified firmwares installed
What's new?
The coolest new functionality in v1.3 is a new backup utility that allows you to perform a backup directly from recovery mode with alt+B. This is done using infernix's and brainaid's nandroid script, which they kindly modified to work in recovery mode. Let them know what you think . The backups are stored in a subfolder in the nandroid folder on your sdcard. To restore them, you have to copy them to your computer, and then flash them with the fastboot tool (sorry, no integrated restore yet).
If you get errors when making a backup, first make sure you have enough free space on the sdcard. it needs around 85-90mb. If you have enough space, then try reformatting the sdcard (fat32 is your best bet).
Other changes of note include
This version includes a new busybox binary that I compiled against uclibc, making it much smaller (1.8mb vs 700kb).
All busybox applets are linked at /system/xbin/bb, which is also in the path. So there are many more standard unix commands available in the terminal.
Many more modules and binaries are included in /system/xbin and /system/modules. They were also optimized for size, so even though there are more modules and binaries, they actually take up much less space than they did on v1.2
I added the terminal emulator application to /system/app. (don't worry, it won't, or at least shouldn't , cause any problems if you already have it installed)
got rid of the normal su binary, in favor of koush's su and SuperUser application. See details here
when you boot up into recovery, it will automatically show the text. You can press alt+L to turn off the text and ogle the background. (did I mention there's a new background? shhh. it's a secret )
fixed the annoying uptime bug, where the uptime is shown incorrectly in the settings
added /data/local/bin to the path. Feel free to add your own binaries/scripts here.
includes the /dev/mtd/mtd6 and /dev/mtd/mtd6ro devices, which allow access to the entire flash chip (other than certain restricted areas used by the radio)
new "ro.modversion" property, that is set to "JFv1.3". The intent of this property is so you can know you are running a modified version, as well as identify which version
added a modified /system/etc/security/cacerts.bks file, which contains additional certificates for cacert.org (courtesy of Disconnect)
added a /system/etc/resolv.conf file with the 4.2.2 family of DNS servers, to allow busybox's ping, wget, etc. to resolve host names
See the attached change logs for a complete list of changes with respect to the corresponding "official" firmware.

Update (01-03-09): Updated the links to point to the v1.31 versions
In addition to the updates themselves, I am also releasing a build environment that can use to build each update from scratch. You can use these to easily make your own custom updates. It includes some utilities that were built from git source. The binaries are for 32bit x86 linux. If you want to run it on a different platform, you're on your own.
NOTE: You don't need these to use my update. Just download one of the updates from above and install it. The build environments are only if you want to make your own customized update.
The general idea of the build environment is that it extracts the original files from the official update (or from my original ADP1 update), and then copies over anything from the various ModifiedFiles folders, then packages it all back up into a ready-to-be-applied update.zip. It does this for the boot image, recovery image and system folder. You can also specify files to delete in the various OriginalFilesToDelete.mk files.
Consider anything new that I created for the build environments (the makefiles, etc.) to be in the public domain. Everything else retains its original license of course.
Instructions:
- extract the build environment into a folder
- download the official update that the update is based on, and put it in the root of the build environment. (note: use my original ADP1 update for the ADP1 build environment. available on this page)
- run make as root. yes, it has to be with root, because the binaries in the 2 cramfs images should be owned by root. (note: I plan on using fakeroot in the future, to workaround the need to be root)
- after make finishes, assuming there are no errors, the update should be in Workspace/update.zip.
Download the build environments here:

Sweet! great timing JF works like a dream!
Btw, love the new recovery background...I feel seizures coming on...
Stericson
Fantastic! Been waiting for your update, looking forward to it. THanks JF and others who made this possible!
Thanks for the great work!!!
Awesome, thanks!
So what would we need to do to replace the browser with Koush's auto-rotating version and how about replacing the alarm clock with Klaxon?
This is awesome! a little pre 2009 present! thanks JF for all that you do !!!
Just posting to say this update worked a-ok for me. Thanks JF for changing busybox and for the new su.

Download the build environment for the version you want, extract it, put the klaxon and browser apk into system/ModifiedFiles/system/app, put in a delete entry into system/ModifiedFiles/OriginalFilesToDelete.mk for the alarm apk and odex, then run make as root.

Will this work on windows vista with cygwin as opposed to a full linux VM?
Are there any specific binaries I need to install?
thanks again!
one last comment... love the Alt+B i know B is supposed to be for backup, but in my mind it stands for BADASS!!!!!!

You might be able to get it to work. You'll need to replace the linux binaries in the tools folder with windows equivalents.
But tbh, you're best bet is to install vmware and get an ubuntu VM running.
Did a quick search and could not find what ADP1 is. Is this the developer version?

Ah, thanks for the confirmation.
Is there anyone out there that can tackle this for me? I'm visiting family through the 5th, and don't feel right installing a linux VM on their computer.
If so, PM me, and I can give you the specifics, but really all I'd like is for the alarm clock to be removed and replaced with Klaxon, and for the browser to be replaced with koush's build that auto-rotates.
This would be for a G1 RC30 build.
Cheers, and thanks in advance!

Thanks JF, I just flashed the ADP1 version and it is working great so far.
Have you attempted to add in the MyFaves app to the ADP build? I had tried a couple of things previously, but I was running into some errors. I may try it with your new build environment later if it is something you haven't attempted.
BTW - for those looking for a virtualized Linux environment, I also recommend Sun's Virtualbox (http://www.virtualbox.org/). It is free for personal use and provides a lot of the functionality that you get from the paid versions of VMWare. In fact, some things seem to run smoother when running Linux virtualized on Vista 64bit; i.e. I can get copy/paste between OSes and auto-resizing guest screens without a lot of extra hassle. Just make sure that you read up on how to use the USB virtualization so you can create the filter for the phone as a USB device.
Great work once again JesusFreke!

You can always do it manually of course. Install the update, then remount the system as rw, then delete the alarm apk and odex and the browser apk and odex from /system/app, and copy the klaxon and modified browser apk to /system/app

Couldn't you also use an Ubuntu LiveCD just as easily? That would allow temporary access to a 'nix environment without touching the existing drive, mount one of the partitions temporarily for your make environments. Just a thought...
This thread should serve as a general source of information for those patching and extending the kernel.
Anyone who does changes to the kernel should drop a note here (especially on those builds that go into FolioMod or TnT)
I'll also try to keep a list of patches and a current config file in the first post of this thread.
Just to make sure that anyone has a common base, the Folio 100 kernel source can be found at TegraMid wiki: http://tegramid.com/wiki/Main_Page
To upgrade to nvidia-10.9.8 apply the attached patch to the source tree.
Note that the zip file also contains a disabled folder, this contains 3 patches that were NOT applied as they prevent the folio from booting.
There were quite a few changes for handling audio devices, this may fix the issues with bluetooth headsets and sound coming from speaker and headphone (not tested though), also there was a change in some wakeup configuration structure for wlan, so this may also fix the wakeup issue.
Changes from DerArtem to support 3G Modems are not (yet) included in the kernel.
I also had two freezes when booting the system wuith this kernel (system_server not responding) however I could not reproduce them.
OK, I'm stupid!
Forget the patches above, I pushed the updated kernel images to the wrong directory (/sdcard instead of /sdcard/sdcard-disk0) So I was constantly flashing the last plain folio kernel on the device.
Damn you shell scripts!!!
Updated the patches above, the kernel should work and everyone should be able to recompile with the patch applied.
I've also attached a binary for users to test the kernel.

If you look into update-nvidia-10.9.8.zip file, you could see that it is normal update file for kernel. So that I guess you rename update-nvidia-10.9.8.zip to update.zip and then update as any other update. But you should better always know what you are doing. If not, wait for full foliomod update.
To weeds2000: thanks for keeping kernel repository updated for the others.

This kernel is based on the stock Toshiba Kernel with modifiactions from DerArtem.
I've added UTF8 NLS support as required by the vold patch as well as the lag on wakeup fix.
Could someone please confirm that 3G support is still working with this build. As I don't have a 3G modem I cannot test this.

i can try install already on folionotion?? just for not reinstall the system..
I cannot guarantee that this works, but in case you cannot boot it should be enough to just flash the ROM again without making a Factory Reset.
Make sure you have an adb connection or some way to get an update.zip to your SD Card in case the device does not boot.
check out wifi drivers from here:
http://git.chromium.org/gitweb/?p=atheros.git;a=summary
is it possible to enable the tunnel support in the kernel?
Has anyone emailed toshiba to request the latest source? it took amout a month to arrive last time (on cd)
Could you please PM me the address you have writen the request to?
I searched the toshiba page yesterday, but couldn't find a developer page or something like that.
Or should I simply contact customer support?
weeds2000, can you attach the precompiled toolchain? i got smp compile error so maybe it is the toolchain im using.
what i did was:
1) download and extract the source
2) download and patch the tegra patch you attached in post 1
3) download the tegra config file you attached in post 1 and extract the config to .config to kernel directory
4) make ARCH=arm CROSS_COMPILE=/path_to_crosstoolchain/arm-eabi-
it was 2am when i did it so maybe i missed something.. lol
EDIT: Nevermind, found the toolchain from android.com.
PS. Anyone happens to have a copy of Tegra 250 technical datasheet?
Hmm.. Cannot get it to boot into OS.. The kernel booted and adb ran..
Also tried the binary you have attached in post #1 but also doesnt boot into OS. Did you get it to boot at your end?
Attached are dmesg and logcat
The image in post #1 should work with FolioMod 1.3. As the display/touchscreen driver seems to have changed it may not work with 1.4.
I'm not 100% sure, but this looks like a problem with the nvrm_daemon binary which is not started or has crashed.
please implemet tun.ko
Hi,
i need the tun.ko for the folio, so i can connect via vpnc to my fritzbox and make phonecalls for free over wlan hotspots. (like i do on my desire)
Please can you provide a tun.ko for this.
Cheers
xoom honeycomb source / git
Just got a note from MCLP on the honeycomb git.
so i downloaded it, and extracted the config.gz from xoom tablet (boot.img, that is) .
the kernel completely compiles without a single error, and no questions on the .config file i used, so the xoom config.gz matches the environment of the git (Koush said he also used it to compile the recovery kernel for xoom)
git is here
View attachment config.zip xoom edition.
now's the question if we can make it run on Folio
update:
removed(too many bugs) is the 2.6.36.3 with the Folio100 ODM_KIT included, i don't see any chance of making it work without, as i read the odmkit, its toshiba custom drivers + tegra for betelguese platform. this is NOT a working source, but inprogress.. but maybe someone else can assist?
Hi,
Usually on linux, there is a kernel loading modules at boot-time framework, cf. modules.conf.
No longer present in android.
When typing lsmod, there is two modules loaded by default : tntfs, and bcm4329 (and voodoo_sound
if you have it).
I'm trying to figure out what is the standard procedure on android : I've noticed on the
init.rc that the tntfs.ko is loaded, but can't figure out when bcm4329.ko is loaded.
Any idea ?
Moreover, I know that voodoo controller is able to load his own kernel module (voodoo-sound)
at boot-time. Anyone knows how the voodoo dev did that ?
My current idea is to modify init.rc to source a new file - let's say init.rc.local - to keep my custom mod. It'll
allow minimal changes when updating+root : just copy the init.rc.local and change the init.rc...
Sounds like we're recreating linux boot framework. lol.
This is something I've done on the HTC Incredible and the Droid 1 in the past, but in honeycomb, this is different, not very obvious yet:
Rather than try to emulate whatever Redhat or Ubuntu has done, which usually doesn't work, I either would use the line where tntfs.ko is insmod'd in /init.ventana.rc (sorry, think that's the filename), and add in the modules you want to add right there. Make sure to save the original file so you'll have a shot at fixing it if you make a mess.
The other thing is just to find some developer that appears to know what they're doing, and download their ROM, like Roach. I just downloaded his prime 1.6 ROM and unpacked it, then noticed immediately that he's got this in there:
/system/etc/init.d/01init{stuff},
Well that seems pretty important, so I did a grep 'init.d' * -R from the / level, and could only see little of importance, not any shell file like initrc pointing to it, just that busybox is linked to it, etc.
I figured it's worth a shot to create the same file structure on the stock ROM (/system/etc/init.d/0X{name} and see if it executes :: Start it with the usual #!/system/bin/sh
# load some modules
/system/bin/inmod /system/lib/modules/cifs.ko (or whatever)
and see what happened, if anything.
Better yet, I'd just send a message to Roach or some other ROM developer and ask.
Good luck -

Tested.
Does not work, because modified room probably calling busybox run-parts.
Anyway I've found a hack, I'm posting it on general section.
As lately some people are asking me about ROM porting I decided to create this new thread where we can share knowledge about this hard task.
Please note this is a Dev talk thread, so DON'T ASK about fixing a particular ROM problem here. Also don't ask questions like "My phone is bricked! please help!". This IS NOT the appropriate place for it. There are plenty of other threads to help you out.
Also note that this is not a step by step guide (and not a guide at all), it's just a point where you can start from. Android is a very complex system and there are many things I don't know yet. So, research and hard work is what you need to learn it deeply. My first tip is Google really works. Don't be afraid to search
Ok, to the basics. Porting a ROM is no simple task. It requires advanced understanding of how android works and how it is organized. Previous Linux/Unix knowledge helps A LOT. As android is based on this O.S. there are many similarities between both. In fact many ppl consider android to be a kind of linux distro.
The very first task to port a ROM is finding a device which is compatible with your own. For example Defy/Milestone2. Then you are going to choose a ROM to port to your device.
As our devices (Milestone2) have a locked bootloader we now need to find a system image that have a compatible kernel with the ROM we are trying to port. This is mainly based on trial and test and takes a long time. You'll be ending flashing your phone several times with RSD Lite. You should learn how to use MotoAndroidDepacker and how to create a fixed SBF.
The basic procedure to try that:
1. Open original ROM update.zip and remove any files/commands that flashes boot/devtree/recovery/anything.
2. Install this new file on your phone via CW Recovery.
3. Boot into bootmenu and enable ADB so you can read logcat while phone boots.
4. Choose Boot/Normal. If your ROM uses 2nd-init you will need to place/edit/adapt bootscripts into bootmenu 2nd-init folder.
5. Check logcat for errors:
- If you're getting HAL errors you're going to need a new kernel;
- If you can start android without getting HAL errors but still getting errors and bootloop on android animation you should try to replace libs with appropriate original ones.
6. Once you are able to boot android you should test it's features to see what needs to be fixed.
This is what I have to say for now. The thread is now open for discussion.
At this week, motorola has just pushed the GB official update for Droid 2 and Droid 2 Global....
Can i try to port this new rom to milestone 2 and after a success boot, fix the radio..??
I was asking that, because some people has success on port CM7 to milestone 1, when it originally maked for droid 1...
tks a lot..!!

It may be possible, but you'll have a hard time fixing the baseband.
You may have to mod the init.rc scripts and find the right radio binaries (rild is one of them) and drivers.
Ask those ms1 people for help, if they are still with the same phone...

I don't know if this will be relevant or not.
I wanted to know if to do any of this, having a Linux distro as OS a must or can I try my hands at it on a windows based machine. I mean I'm sure that a Linux distro will give certain advantages (as Android is based on UNIX/Linux) but can we get things to work a 100% on windows.
If yes, then will someone be kind enough to get give the list of all softwares etc. which will be required to do the job on Windows machine as well as a Linux machine.
I do know a few softwares but I'm not sure if I have an exhaustive list. I would like to learn and try and at least be able to modify in bits n pieces to begin with.
I apologize if this wasn't supposed to be asked in this thread.
The only thing i can get from SBF is a bunch of smg files.
But the only ones i can open are
preinstall.smg
CG39.smg
Is there a way to open/see the rest?
2)
Im trying to modify the CM7 rom, what boot does it use? 2nd-init or 2nd-boot?
i guess it is second-init. but not sure
thanks a lot for this !!!

SMG files are disk images of certain partitions of your flash memory.
You can only open CG39.smg and preinstall (CG66.smg) because they are the only images in ext3 format. The rest of images may be on ramdisk format or some proprietary format. For more details on partition codes take a look here:
http://and-developers.com/partitions:cdt
You may be able to open and see contents of other partitions but the only one that matters aside from system and preinstall is the boot partition (CG35.smg), which contains the init scripts we should mod in order to make they work with 2nd-init. Boot partition is in ramdrive format. More details here:
http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
http://elinux.org/Android_on_OMAP
It is easier to unpack boot image using Dsixda's Kitchen here:
http://forum.xda-developers.com/showthread.php?t=633246
Edit: To see what boot your CM7 uses just go inside /system/bootmenu/config and look for a file called default_bootmode.conf. That should be the boot method used. It's normally 2nd-init.

I do know a few softwares but I'm not sure if I have an exhaustive list. I would like to learn and try and at least be able to modify in bits n pieces to begin with.
I apologize if this wasn't supposed to be asked in this thread.

Don't worry, this is the right place
As for your question: yes you can work in windows if you like, but using at least a Linux VM is more productive. I don't have a full list of applications to give you, as different mods may require different tools, but I advice you to have at least:
- Notepad++ (essential for editing text files and keeping linux end-line format);
- dsixda's Android Kitchen (http://forum.xda-developers.com/showthread.php?t=633246)
- 7zip (or some other compress tool you like)
- Moded putty for ADB as working with windows command prompt really suck (http://forum.xda-developers.com/showthread.php?t=803225)
- Oracle Virtual Box (if you are going to use linux VM).

SMG files are disk images of certain partitions of your flash memory.
You can only open CG39.smg and preinstall (CG66.smg) because they are the only images in ext3 format. The rest of images may be on ramdisk format or some proprietary format. For more details on partition codes take a look here:
http://and-developers.com/partitions:cdt
You may be able to open and see contents of other partitions but the only one that matters aside from system and preinstall is the boot partition (CG35.smg), which contains the init scripts we should mod in order to make they work with 2nd-init. Boot partition is in ramdrive format. More details here:
http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
http://elinux.org/Android_on_OMAP
It is easier to unpack boot image using Dsixda's Kitchen here:
http://forum.xda-developers.com/showthread.php?t=633246
Edit: To see what boot your CM7 uses just go inside /system/bootmenu/config and look for a file called default_bootmode.conf. That should be the boot method used. It's normally 2nd-init.

Thanks again r2beta
thanks r2beta0
- Notepad++ -- got it
- dsixda's Android Kitchen -- downloaded (need some link for a how-to on its usage)
- 7zip -- got it
- Moded putty for ADB -- got it
- Oracle Virtual Box -- can't install Linux on my system as this is a work machine
dunno if I can do without the last option.

Oracle Virtual Box is an application that lets you run an operational system on a virtual machine, in other words, it doesn't install linux on your real computer. It's a very useful tool that I use everyday. Google for it and learn a bit, you won't be disappointed. About kitchen: the link I provided was download + guide. Read it again. If necessary read the full thread.

I know a bit about virtual box but as I said I'm not allowed to have softwares not approved by the IT team to be present on the system. Though I can get away with small things like notepad++ and 7-zip, having virtual box on my system may raise some eye brows.
I'm trying to arrange an alternative system.
Me neither. I must do almost everything at home, and at this very moment I simply don't have any free time. I'm afraid you're not going to see me here very often anymore (maybe in a few months? a year? well, it might be a bit too late for milestone2...)
hi. Have a question, I want to remove baseband from a flashable zip (lets say, CM7 from Tezet) , is it posible? I dont know where to look for it (baseband). Thanks!!
Baseband is located in \system\etc\motorola\bp_nvm_default\
But don't remove it, just replace it with files from ROM, which have baseband you want.

Hi All,
Just a quick question. I have ported Paranoid Android 2.10 to MS2 but the problem I am facing is that Reboot goes through Bootmenu and I have to choose reboot from Bootmenu again.
Any inputs?
Thanks in advance

I meant to get to it last night, but I was tired after work and fell asleep watch tv. Eventually, later tonight, I'll be uploading PA for MS2. Check my Defy PA thread in 12-14 hours cause I'm about to go to work and I'm not gonna feel like making a MS2 PA thread or updating my Bravo PA thread -- but the Defy Thread is always up to date when I put out new roms.
Also, I'm looking to get either a Defy or MS2 -- I've heard that there's 3G issues with AT&T users (which I am) with the MS2 -- Apparently the MS2 has different 3G frequencies than AT&T. Are there any AT&T MS2 users who are knowledgeable about that? While I can deal with no 3G, edge only, calls only -- I need to make sure I can at least do that before I commit to something.
I'd rather have the MS2 because I want a hw keyboard and I don't have the $300+ to try and get a Photon Q LTE from eBay (and I don't have to change up my repos if I get a MS2). If anyone here knows of a phone that's AT&T compatible, Defy code compatible, and has a keyboard, please let me know.
Thanks.
//Normally I'd post the latter half in the Q&A section, but ya'll don't have one so I'm just gonna piggyback
//My Bravo doesn't have a Q&A page either -- it needs one that's not my PM box...Don't PM me on how to root your phone and flash CM7 -- read one of the 5 guides on the first page of both General & Dev...:silly:
Ok devs need some help here.
I am trying to port a rom to our Milestone 2...but it bootloops on rom animation.
I tried to logcat it but I don't think it gets as far as adb server to detect the device.and just keeps saying "waiting for device"...so I end up with no logcat to diagnose the problem.
I can logcat my current working rom but only after the phone boots....am i missing something here? please, help
Any help is very much appretiated.
Thanks a lot in advance
Warning/disclaimer: This thread is intended for those who already know how to compile a kernel and have a working knowledge of Linux and its derivatives. There shouldn't be a great deal of risk involved, but you are responsible for what happens if you decide to follow these instructions.
Polite request: Please don't post replies to this thread that aren't of a technical nature directly related to compiling, modifying, or testing the kernel.
Introduction:
It appears as if Lenovo have released a buildable and bootable kernel source. I've done some preliminary testing with it. However, it would be better if we could get lots of people building and running the kernel, so that we can spot any remaining problems. This is also an opportunity to start hacking it to add/fix features such as USB OTG, etc.
Kernel source:
Get it from the Github repository at: https://github.com/gmarkall/lenovo_a1_07_kernel
Toolchain:
The Makefile seems to suggest that Codesourcery 2010q1 has been used by Lenovo to compile the kernel. Get it from https://sourcery.mentor.com/sgpp/lite/arm/portal/release1293, and make sure that the arm-none-linux-gnueabi-* binaries are on your path.
Building the source:
You may wish to edit the Makefile around line 192 to set CROSS_COMPILE=arm-none-linux-gnueabi- instead of the hardcoded path that is the default.
Then, to build the kernel:
Code:
make distclean
make a1_07_defconfig
make uImage
Booting the kernel
Normally, Android devices have two boot images that consist of a kernel and a ramdisk. One boot image is for the recovery, and the other is for the Android system. This makes it safe to flash a new boot image containing an untested kernel for the Android system, since the recovery can always boot up using the other boot image. However, the A1, by some bad design decision, only has one kernel - the bootloader always loads the same kernel, and just loads a different ramdisk depending whether it is to boot into recovery or system. As a result, it is not safe to flash a kernel to your A1 unless it's already been tested, since a bad kernel will make it impossible to boot from the internal memory, and you'll need a bootable SD card.
The solution to this problem is to make a bootable SD card for loading the kernel and ramdisk from. A bootable SD card consists of two partitions:
* A small bootable VFAT partition, that holds the X-Loader (MLO), U-Boot (u-boot.bin) and the kernel (uImage).
* An ext2 partition that holds the root filesystem.
In order to create a bootable SD card, use the omap3-mkcard.sh script that is attached below. To invoke it for making /dev/mmcblk0 a bootable SD card:
Code:
sudo omap3-mkcard.sh /dev/mmcblk0
You may need to hack the script if your SD card device isn't a /dev/mmcblk* one, since the script searches for partitions denoted "p1" and "p2" - this may need changing to just "1" and "2" respectively (thanks Xbdesign and Brancaleone for this).
This will create the necessary partitions, set the bootable flag, and format them. You will then need to mount the first partition (e.g. /dev/mmcblk0p1), and copy MLO and u-boot.bin to it (also linked below). Then, copy the uImage that you built from your kernel tree, which will be located in /arch/arm/boot. You can now unmount this partition.
Next, mount the second partition (e.g. /dev/mmcblk0p2). This will need to contain the same set of files that the initial ramdisk contains. There are two different ramdisks that you might want to use - one is from the Cyanogenmod 7 build, and the other one is from the stock system. Download links for these are also below. To extract the ramdisk, copy it onto the SD card second partition, then run the following commands (assuming the ramdisk is called ramdisk.ub):
Code:
dd if=ramdisk.ub of=ramdisk.img.gz bs=64 skip=1 # Strip off the U-Boot header
gunzip ramdisk.img.gz # Unzip
sudo cpio -idmv < ramdisk.img # Extract the cpio archive
Then, unmount the second partition of the SD card.
You should now be able to remove the SD card and insert it into your A1. Power down the A1 and power up again, and it should hopefully boot from the SD card and load your kernel. If it's booted from the SD card and loaded your kernel, you should be able to see that it was compiled on your host by looking in Settings -> About Phone -> Kernel Version.
Troubleshooting:
This is not a comprehensive guide, just a few pointers to where a problem might be - please post replies to the thread to get troubleshooting suggestions.
System boots up, but is not running my kernel - it didn't boot from the SD card. If the A1 is plugged into the charger/USB, you sometimes need to reboot multiple times before it boots off the SD card (I think it doesn't always turn off fully when the charger is plugged in).
The static Lenovo logo flashes up over and over again - it's booted from the SD card, but didn't manage to load your kernel
The static Lenovo logo comes up and stays there/goes to a black screen - it's probably loaded your kernel and mounted the root file system, but failed to mount /system. Try running adb shell to see what happens. If you get something like
Code:
/system/bin/sh: no such file or directory
then your kernel is running but /system isn't mounted.

Ramdisk for Cyanogenmod 7
Ramdisk for ROW 2643 stock release
I've added the two ramdisks that I suspect will be most common - if you need another ramdisk, you'll have to extract it from an OTA.
Also, I compiled a tun.ko - www.doc.ic.ac.uk/~grm08/ideapad/tun.ko
Here's a cifs.ko - http://www.doc.ic.ac.uk/~grm08/ideapad/cifs.ko
EDIT: AutobahnA1 and infraredevans have confirmed that tun.ko works on ROW_2643.
EDIT 2/3: Please test out cifs.ko! (It doesn't work - it needs slow-work.ko. Will get that done when I can. Thanks to Ilikecokethree on the Lenovo forums for pointing that one out).
你懂中文吗，大神！
我是中国人 关注你的帖子很久了，我不懂英文，用翻译软件看的大概，我们这里很多人支持你，都在用你的rom 很棒！比联想官方的好多了，谢谢！
I think I did exactly the steps as you told, but it still boots the original kernel, may something be wrong? Thank you very much.
PS: I'm a chinese too, and my English is not good either

I wish I had the knowledge to work on it myself but I am far from taking over such tasks...do not have the slightest idea about how these things work.
Good luck and please keep us informed!

Geolocation bug has nothing to do with kenerl. It's a missing entry in framework-res.apk in ROM from Lenovo

Sounds like it's booting from eMMC instead.
Can you post the partition table of the SD card as listed by fdisk, and also a directory listing of each of the two partitions? I ask this to confirm what's happened - seems like you're the first person to follow these instructions, and it's quite possible I made a mistake somewhere.

Apologies for the off-topic, but I think that we are discussing two different things here: I am referring to the Geolocation bug, which prevents me from e.g. checking in with Foursquare by using only WiFi location information (active GPS signal is needed) while you have solved the Geocoding bug, which has nothing to do with the Geolocation one...
Please correct me if I am wrong.
@Graham: I plan to install the CM7 that you have been working on (with the feedback from other users - I keep an eye on that thread!) but since I use my A1 for professional purposes as well, I would like to make sure that everything is working fine before moving to CM7. Apologies for not being able to contribute to the beta testing of CM7 but I am really looking forward to seeing a version based on the source code provided by Lenovo, which I think will lead to a more stable version of your CM7. I cannot thank you enough for taking the time to work on this, really!

I think that whether it works in CM7 or not, it almost certainly isn't a kernel issue. I'll test it by signing up for Foursquare and give it a try out on CM7 to see if it works later on. Will post my findings in the CM7 thread.
Hi Graham,
just gonna pile up several questions/thinkings and feel free to comment them the or answer on your liking
We do have few hickups on CM7 but I am more excited about idea of having proper recovery then ironing current CM rom that works more than satisfactory right now. Do we have enough code (I assume that target here is u-boot) on our hands that someone can implement necessary changes to internal partitions and boot procedures?
what is your opinion on replacement of u-boot with something else? for example LK loader or to be more precise with its current HD2 implementation known as cLK. it allready has some neat features like HBOOT like GUI, ability to change partition sizes on device itself (without computer), ability to boot from different partitions (would be nice to have android and ubuntu side by side loaded on our devices) and last but not least it has fastboot support enabled...or is it better way fill up u-boot with desired features if possible?
so...just my wishful thinking...not enough knowledge on my side to do anything regarding all this just hoping that some of you, more capable guys gets interested in this

I do want to implement something that's pretty much as you describe. My biggest motivation is that it's currently not safe to flash a kernel since you can break both system and recovery that way in one go - I really want to make the boot process more robust.

Here it is: http://www.doc.ic.ac.uk/~grm08/ideapad/cifs.ko
To compile it I had to copy md5.h from another kernel source to fs/cifs in the kernel tree. I also had to edit init/Kconfig so that CONFIG_SLOW_WORK defaulted to yes. I configured the module with the options:
Support Legacy LANMAN servers which use weaker security
CIFS Extended attributes
CIFS POSIX attributes
and without statistics, debugging, or experimental features. Let me know if this is a suitable config - I could always tweak it and build another one.

I did - I didn't have any problems, but my random guess about how to solve it could be to install ia32-libs. If installing that doesn't solve it, can you post a bit more detail about the problem?
I am using ubuntu 10.04 LTS and just cant install / find Getlibs to install a 32-bit version of xulrunner :-(

Do you need that to run the installer? I just downloaded the tar version instead and extracted it. I saw there was an installer as well, but I thought it would be more hassle than using the tarball so I just ignored it.
