Hey guys,
I am trying to port the ClockworkMod recovery to the incredible S, and everything goes fine until the last step, getting the files neccessary from the recovery image using mkvendor.sh works, but it produces a kernel that is 1.8GB (!), so when I go to build, the recovery is far too large and it aborts.
Anyone know why this might be happening? Surely the kernel can't be that big, the recovery partition is only ~8.5MB and the dd of the recovery come out the same, so how is the kernel so huge?
Any help will be greatly appreciated
EDIT I have uploaded the dump if anyone needs / wants to take a look: http://www.multiupload.com/JSY1HUI6Y7

Try this,
Get a working ROM for the Incredible S, and extract boot.img
Extract the the kernel from the .img and place it in your
Code:
<android-source-root>/out/target/product/<phone>/
-- overwriting the 1.8GB kernel (ie recovery-kernel)
Then run
Code:
make recoveryimage
to pack it into an img
I got a file called boot.img-kernel.gz which wouldn't open as an archive so I just renamed it 'kernel' and that got the image built... now to see if it flashes! thanks for the pointer
Hi all! I'm not a dev but i really want to do something for this phone so i'm trying to build a custom kernel.... if anyone have tried the same report here the issue, i will do the same!
I have the pre-requisites for compiling a kernel set up. However I am more interested in getting ClockworkMod Recovery working on our phone as that will encourage developers and we can then start looking at getting CyanogenMod 7. I made a topic here asking for help but I haven't received any replies yet.
I have just compiled a kernel but it doesn't work.... this because - i think - i used the initramfs provided by leshak for the i9000.... now i'm trying to extract from phone......
Kernel
Hi Skin1980, I also compiled a (stock) Kernel two weeks ago - problem is, Samsung does not use the "normal" way of storing it in a boot.img file. That is why I wasn't able to push it to the phone or at least fastboot it. I would be glad to hear from you how exactly this is possible, if you find out.

I used the redbend_ua you can find here to write zImage to bml7.... how do you do with initramfs that is missed when you build the kernel?

Have you managed to extract initramfs with redbend_ua?
If you don't mind, please take a look at this post. There is a step build/tools/device/mkvendor.sh device_manufacturer_name device_name /your/path/to/the/boot.img. Because Samsung doesn't use this boot.img building a recovery looks tricky. Any suggestions would help.

and if we can find the initramfs i think that is not difficult to modify the recovery to allow unsigned zip files installation
Perhaps, we could use parts of the following method:
h**p://android-dls.com/wiki/index.php?title=HOWTO:_Unpack%2C_Edit%2C_and_Re-Pack_Boot_Images
To extract the ramdisk from the boot.img, they do the following:
Then, look for a bunch of zeroes followed by the hex 1F 8B (which is the magic number of a gzip file). Copy everything from the first line of the file, through the zeroes, and stopping at the 1F 8B. That is the kernel. Everything from the 1F 8B through the end is the ramdisk. You could save each of these files separately. In order to see the contents of the ramdisk, you need to un-gzip it and then un-cpio it.

I know that we don't have a boot.img, but we do have an image including kernel and ramdisk - this should be very similar. And if you can locate the named headers in the file, the extraction should work. Further info and some useful commands can be found behind the link.
Sadly, I won't have time to try this before next weekend...

Which file are you referring to? I have some time, I can give it a shot.
EDIT: I found "initramfs.c" and its object file "initramfs.o" under GT-I9003_Kernel/kernel/Kernel/init from the Samsung opensource tarball. Don't think that helps us though.
@rb210: I mean the dumped bml7 partition. It's an image of a partition with a kernel and ramdisk in it, or did I misunderstand something?
PS: You could try "SGS kernel flasher" from the market. It's got a backup option - look if it does produce the same image of the bml7 partition (I tried it, it did a backup image of around 8MB on my SGSL, which is about the size of bml7, as far as I remember). It would be faster and easier to carry out than using a script.

But ramdisk=initramfs?

Ah I see what you mean. I was trying to figure out how to extract the initramfs from the opensource package from the Samsung website. I figure if they're providing the kernel and platform, there's got to be an initramfs somewhere. You'll are talking about trying to extract it from inside the phone itself.
I'm still not sure how this is going to fit in with porting Clockworkmod as per that method in the blog post because it's still an initramfs and not a boot.img. Getting custom recovery is vital to attracting development for this phone, we should not make the mistake of overlooking this.

Hi All,
Seems like there is a lack of information on how to create pre-rooted system images for those with unlocked bootloaders.
There is a new .146 firmware available now but we're still waiting for it to be rooted.
I had messaged Bin4ry previously and he had provided a rough guide. I do not have a X10 nor the knowledge to create a custom yaffs2 tool. So I'm sharing the info here and hope one of you can help with this:
Okay here is what to do:
Grab another SE Handset and unyaffs your system.img to it's system partition in recovery mode, after that connect with adb to recovery and change the system. When you done all your changes use nandroid to backup the modded system.
I used a X10 for that.
The problem is that SE is using a special yaffs2 format. If you want to use mkyaffs/unyaffs you have to change it to special SE-format. How they use yaffs is determined in their kernel sources, i'm tooooo lazy to create a custom mkyaffs for SE phones. but now you know what to look for, maybe you create one ?
Regards
Bin4ry

OK . We all i believe find it chaotic to organize in forums now. So this is a thread just for ideas and problem with cwm or twrp on our device.
All that i have found now is that recovery.img is somehow backed with boot.img. So i have to ask if there is any developer that can look inside this.
Help appreciated. We (developers) have already compiled TWRP and CWM ( me via ubuntu and clockworkmod recovery builder) and none of them is booting.
You might want to look at xperia p boot.img??? Same processor u8500 same screen size. I'm a noob. Just said what I felt. Coming from xperia device where our recoveries are always packed inside boot.img
In ramdisk . /sbin/recovery is where our recovery binary is present.

also coming from xperia forum and for My xperia U and have also novathor u8500 and i have asked dev to explain mothod used in XU for port this method to GIII mini but no reply from him now in XU the recovery are in tar and flashable to phone without odin or another flash only by ADB + run me script in commande window inside recovery tar we have unziped recovery ( icone ....) and some files relative to phone ( fstab ..... )
How is it going? Did everyone stop developing or are you guys just moving in silence trying to figure things out?

Good to know! Give us a shout if we can help somehow.
currently working on cwm 6. dont know why i cant boot
Perhaps need to no only make recovery but also kernel ?
If this 2 filz run together
Sent from my GT-I8190 using xda app-developers app
From what I understand, You just need to write a piece of code in the ramdisk init files to execute the recovery during boot. No need to modify the kernel.
#pitchblack5691#
If any one is interested i got a dumped ram disk also a got it rebuild-ed,
and yes the recovery scripts are there plus the pngs etc.
I also believe that the device has 2 recovery's, they are the same one just acts as a backup.
is an idea
i explain when you make recovery and extract it you find some files inside ( fstab , RC , init , propr ...
now we have also one with CM device info the device have not CM rom and also have not CM kernel her why i posted this comment because when you extract stock recovey you find kernel part and when you extract boot.img find recovery part now this 2 files perhaps have dependency to work together ? is an idea do not yell at me :silly:

I sent info about device to that developer. That app is now supporting our golden for full backup incl boot & recovery.img with .zip from here. Only problem is we dont have a working custom recovery to flash that .zip with :/
as Faria wrote above should change the recovery that is in the kernel and the same meter and the same rom in it and in the kernel for which you go just tell me that the two are complementary if a move (size , addition, retirees), the other answers are more about the two is that one feature that the other is that we will say to his control as .
now change I believe that both will adjust in any case theoretically
I believe the next step for the Droid Turbo are system images.
With MofoRoot, the next goal is to create a system image that is lollipop 5.1 and has root.
I've only flashed system images that were created up to this point but I'd be interested in learning how to take apart a system image and go as far as changing/manipulating it have wifi tether and root. Anyone have any good suggestions on where to start learning?
I plan to collect what I discover in this thread.

You will need a different kernel to work with a 5.1 or 5.0 system image. We cannot flash a kernel with this method yet just system images.
Right, so the only thing we can do are modified "roms" based on stock. Can't flash recovery or kernel since those are on separate partitions.

Not going to work. You need to mount an ext4 image which is not what that tool is designed for. I'm currently doing so by using Linux and mounting the image as a loop device. I can create a guide for doing so if there's demand.

I'd definitely be interested in a guide. I just wish there was a tool for windows that would work.
You can do it on windows but it's way easier on Linux.
I'm gonna get Linux back up and running and see what I can cook up.

All I want to do is build a flashable img with a modified hosts file. I've found a guide for mounting the image as a loop (which Ive done....) the issue Im running into is changing permissions to be able to actually edit the file once its mounted.
Guess I'll read more and keep tinkering..

Open your file manager as root, then open the file.
