Messing about with fastboot on the HTC Hero Orange UK

Hi, since this is my wife's HTC hero from Orange UK, I'm being particularly careful with it. I'm new to xda-developers/HTC platforms (but not new to doing horrible things to embedded platforms) :>
I've been messing about with the phone all evening - downloaded that ROM image from the other thread and pulled it apart to look at the OS files etc - the standard break-a-new-embedded-linux-platform routine.
Anyway, if you hold down BACK when powering on, it enters the bootloader mode with a "FASTBOOT USB" prompt, which sounded interesting. I got a copy of the fastboot binary, and extracted the kernel and the ramdisk images from "boot.img" in the "HEROIMG_Hero_HTC_WWE_1.76.405.1_R3_WWE_release_signed.zip" (using split_bootimg.pl).
Just as a quick test, I tried booting them with:
fastboot boot kernel.img boot.img
since the above just boots a kernel from RAM, and not actually flash it. Anyway, fastboot claims it downloaded and booted it ok, and the phone shows the "HERO" logo. Unfortunately that is as far as it gets. However, if I reset the phone, it boots perfectly fine from the kernel/ramdisk in flash (phew!)
Since it doesn't actually boot into android proper (and doesn't show up as a USB device), I don't know if (a) its showing the HERO logo, but failing the signature check, or (b) actually booting, but crashing 'cos the kernel/ramdisk aren't quite right. I'd guess (a) myself, but I'm new to messing with HTC bootloaders.
Anyway, in case they're useful, the details of the phone from the fastboot mode are:
HERO CVT SHIP S-ON
HBOOT-1.76.0004 (HERO10000)
MICROP-010f
TOUCH PANEL-SYN0104
RADIO-6.35.04.25
Jul 3 2009,15:22:21

That method of entering fastboot is the same as the magic. Check the magic / sapphire wiki and have a read as I suspect the magic is its closest relative and a lot of the magic stuff will work...

Aha, thank you very much, that gives me more information!
Anyway, I just tried booting the boot.img itself instead of splitting it up with:
fastboot boot boot.img
This time, it booted right into the full android! Checking /proc/config.gz:
On the phone booting normally, it says:
# Linux kernel version: 2.6.27
# Fri Jul 3 07:52:06 2009
On the phone booted with boot.img extracted from that zip, it starts:
# Linux kernel version: 2.6.27
# Thu Jun 25 14:16:01 2009
So it seems as though it can boot the boot.img: AFAIK config.gz is hardcoded into the kernel binary. Now: is there a signature in the boot.img file?

Erm, I'm either hallucinating from lack of sleep, or I appear to have a root shell on it now. e.g. I can see the contents of /data from "adb shell":
ps reports: [snip]
root 43 1 3332 164 ffffffff 0000e8f4 S /sbin/adbd
root 619 43 748 340 c005ef5c afe0d08c S /system/bin/sh

com.soundroid2012.piano.apk
jg.entertainment.abook.four.apk
com.maplekeycompany.apps.shake.apk
net.peterd.zombierun.apk
All I did was
1) pull the boot.img apart with split_bootimg
2) gunzip the ramdisk
3) hexedit the ramdisk to set ro.secure=0 (couldn't be bothered faffing about with cpio)
4) gzip the ramdisk
5) rebuild the image with mkbootimg. Oh you need to specify a different base address. Example command line:
/tmp/mkbootimg --kernel boot.img-kernel --ramdisk boot.img-ramdisk.insecure.gz --cmdline 'no_console_suspend=1 console=null' -o test-insecure.img --base 0x19200000
Then I just booted it with "fastboot boot test-insecure.img"

You're ready to build your own rom images ;-)
You could start by preparing your own rooted recovery with nandroid.
For a quick and dirty basic recovery image, just download one from sapphire development forum, replace the boot.img-kernel with a working copy for your hero.
Then rename init.sapphire.rc in init.hero.rc in ramdisk image.
You can simply extract ramdisk image with:
mkdir boot.img-ramdisk
cd boot.img-ramdisk
zcat ../boot.img-ramdisk.gz | cpio -idv
make your changes to ramdisk files
search internet for a script named repack-bootimg.pl
add the new base parameter to mkbootimg line in the script
cd to directory where you unpacked your boot.img
repack-bootimg.pl boot.img-kernel boot.img-ramdisk newboot.img
fastboot your recovery
then you can use nandroid in the recovery image to make a full dump of your rom and use the newer version of boot.img you have in your device to rebuild an up-to-date recovery or any kind of rom (you could start by preparing a copy of your original rom by changing ro.secure=0 in both boot.img and recovery.img).
By the way, I noticed that kernel in HERO uses sapphire fixup. The currently available version on the net is not booting on sapphire (magic) 32A, but it resets after a few minutes.
Maybe the kernel version in your orange hero introduces compatibility with sapphire boards. Well, really I suppose it won't, but if you get a nandrod backup and post your current original boot.img, magic 32A board owners could give it a try while we are waiting for HTC to release updated kernel sources for Magic and Hero.

No, no signature in standard boot.img, you have to zip it and sign the resulting zip. But no signing keys except for test-keys are available to the public, so I suppose your spl (S-ON) wil not allow you to directly flash rom images from fastboot command line.
However it seems your SPL allows you to fastboot a repacked boot image, so it should not be a problem to use a recovery image to flash whichever rom mod you like.
I suggest you not to flash any SPL you can find on the net, I suppose you have the newest ad no image of your original SPL is available (there is one from a leaked hero image, but yours seems to be newer)
Bye

Yeah, my thoughts exactly, I'd rather not flash the SPL if I can help it: I don't fancy explaining to my wife why I have to rip her phone apart to find the JTAG contacts I'll upload the boot.img later though.
Thats odd about the reset after a few minutes thing: hardware watchdog timer of some sort?

Well, really it's a little bit mor than a minute or so.
I suppose it's not an hardware watchdog, I don't have access to console debug messages.
Really the reset is a good sign, if you try booting dream or sapphire 32b kernel on 32A boards, it hangs forever.
If you extract piggy.gz from the kernel and hexedit it,you can find hero kerel initializes the hardware using the sapphire fixup.
It could only be that htc reused the same source and fixed hardware details and forgot to change the fixup routine name or that they are prepare to build a kernel able to boot on both hero and magic 32A boards.
32A and hero use the same new base address for kernel and ramdisk loading 0x19200000.
our boards have more memory than dream and 32b boards.
I suspect htc is using a stacked ram configuration and they changed the init code for the number of banks in memory.
In 32A they changed ram location for fb, ram console and maybe gpu1. It was a real mess to guess every change, so I stopped recompiling and rebooting the kernel after a dozen of times ;-) Waiting for htc to release the patched source code ;-)
The radio rom on hero seems to be is newer than 32a's latest available but I don't want to try a flash, you know what I mean ;-)
The available hero SPL shoud work on sapphire (and on blackstone and topaz too) and maybe the newer radio rom requires it, but... I prefer not to brick my Magic.
Have a nice rom rooting time. You could want to give superuser.apk a try.
People on this forum is asking for rooting status on hero, I suppose you'll be able to announce them your succes in a short time.

Wow! That was Fast! Lol..... even thought there is still some work to do.

i feel honoured to have been one of the first to read this i still dont have a hero yet =[ gotta wait till august when i get my ema might start scrounging and saving what i can get so i can get it sooner
Well done to you sir what a fine job uve done, gz =]

I'm waiting for my Hero as well and I'm completely new to android.
But like you I develop for and work with embedded Linux systems so tearing ROMs apart was pretty much on top of my list when my device should arrive .
I don't know what the 'recovery' image does on Android systems, but as I read it like this: You can temporary boot a rom (or at least a kernel and it will get the rest of the system from the rom area) through the fastboot method.
So yes, then you have temporary booted into a rooted ROM. But how to make it permanent? Because if you modify the ROM and flash it back it will probably not work because it detects its modified, right?

Trying to make a "dirty recovery image" to dump full roms using Nandroid Backup
Hello Dalroid,
I read your post and was able to do the following:
1. Using split_bootimg, extract the ramdisk files from the Stock HTC HERO Rom found in the XDA forums.
2. I downloaded the cm-recovery 1.4 image from Sapphire and used split_bootimg on it as well.
3. I copied the extracted kernel from the HTC Hero ROM and replaced the one from the cm-recovery of sapphire.
4. I renamed init.sapphire.rc to init.hero.rc in the extracted recovery image folder.
5. This is where i have trouble. I am using the repack-bootimg.pl, but I am unable to repackage the image.
I did note that you stated that some base parameters needed to be changed in the script for this to work. Could you please shed some light on what I need completed in order to repackage. Thank you in advance.
EDIT: I found one problem so far, I do not have mkbootimg or mkbootfs on my computer. How do I get these on my computer?

I built my mkbootimg from android source code (android.git.kernel.org), but if you prefer you can find a prebuilt binary from http://rapidshare.com/files/249629878/PortTools.rar. I'm not the author neither I tested it, just searched for mkbootimg in forums and pasted the link for you.
If you use the standard mkbootimg, just add --base 0x19200000 the the mkbootimg line, otherwise the boot.img will be generated with standard load address which won't work for hero (or for my 32A Magic).

This is pretty exciting stuff
I really want to remove the SIM lock from the Hero - is this something you can do now you've got su access?
Is it going to be possible to have a 'how to' guide for the Hero to tell us what to do to get the phone unlocked?
I want to see someone install the Magic image on the Hero - it should fly with the extra RAM

Just out of curiosity, what would happen if I booted the original cm-recovery-1.4.img on the Hero?
My phone will hopefully arrive tomorrow, and the first thing I'd like to do is create a backup with the nandroid script.

I'm new to all this, so I'd be grateful for some more information: is the Dream and Hero hardware too different to boot the same image? Or would it be possible to create multi-platform images?
I already downloaded the modified image from that thread and have extracted the same kernel, so I should be all set.

Finally the tutorial
Make your own Android Build for the HD2 by domineus ​I have always lived by these words- if you give a man a fish, he can eat for a day; but if you teach a man to fish you can eat for a lifetime. Android on the HD2 has always been an interesting thing for me and I know a lot of people that want to create their own builds, but have no idea how. If you ask a build creator or maybe someone in the htc-linux-chat how to get started, there may not be an answer. In fact, some of the perplexing behavior has left me puzzled in several ways - as if how to get an android build is a vaulted secret of knowledge like the holy grail. To be honest, it's not. It's a bit of hard work, a few nods in the right direction, and ultimately it's a community involved project. Just like miui development is a community project spanning actual continents to get this thing on our device every single week! It has led to a lot of questions, in my inbox, of how to begin. For a long time, the answer to the question was not answered until Cass helped me out. I want to do the same and contribute how to get a build of miui (or any android build) to the HTC HD2.
Things you will need
In order to properly start android development, it would be a good idea to make sure you have the following (a lot of it is no duh when you think about it)
A computer running linux
I can't stress that enough. While there is a lot of things you can do in windows, you will need some sort of linux distro in order to get android properly running on your HD2. There are a lot of linux distros you can use; with many using ubuntu as it is the most user friendly. I use Fedora and I am quite happy with the results. It's simple and effective. It gets the job done. Get a distro that you feel can get the job done.
Android SDK - either windows or linux
Android SDK is something that can be freely accessed and downloaded from the following location:
http://developer.android.com/sdk/index.html
It is a developer environment, but probably the most important thing you can use here (for the time being) is logcat. Logcat provides you to visually see the libraries and files working together to get android to work as well as if you run into an issue, it is the first thing you should resort to. For instance, boot reloop? Take a look at your logcat and try again.
A kernel
There are quite a few kernels available for android previously and they are divided into evo kernel or nexus one kernel. Many builders have transitioned to an evo kernel for PPP and a few other nice details but it is totally up to you. I highly recommend hastarin's kernel. For most of the time, it works well. But as you have noted, on MIUI, it hasn't been working as fantastic on other builds.
Donor Files
This is a bit difficult to find because it appears that the files that work best are nexus one builds without CM6.1 modification. So far, only one chef has that and it is tytung's nexus one build. Regardless of whose files you're using (e.g. tytung or darkstone's system which is the preferred choice) you will need a well working android build. You will be pulling several files in order to port.
MIUI itself (well any build honestly just miui is a good example)
This is a given. However, if you download from miui.com you will probably have an untranslated rom with odex files. That's bad. And in Chinese! It would be a good idea to browse the English forum for a deodexed rom with appropriate english translation (apps and frameworks)
-If pulling files from windows, you will need this
system extractor
http://uranus.chrysocome.net/linux/explore2fs-old.htm
I use that if I download in windows. It's relatively straight forward and it allows you to pull the files you need from the system.ext2 you're using and copying them to folders necessary.
build.prop
This you will need. You can find one here:
http://www.multiupload.com/B59IU3S6XY
Patience
Probably the most important thing. One thing I have noticed is you need patience to make it through. Sometimes, your build works, sometimes it doesn't. And it is difficult to still keep going. But gotta pull it all in and keep trying...it does pay off.
Okay so you have your files, a nice linux distribution, your build you want to port (MIUI preferrably) and you're ready to go. Now it's time to begin the process!
Step One - The Setup
I usually grab my files in windows before transitioning to my linux distro to finish the process. If you using windows 7 and you are using explore2fs, you will definitely have to right click on the exe and make it compatible by selecting compatible with windows vista. The file should also need to be run by administrator. If you don't know how to do that you can google compatibility in windows 7.
First thing is first. Create a new folder, you can call it donor_files if you want because name is arbitrary. The most important thing is to just name it. Within that folder, create a new folder called system. Enter the system directory and create a new folder called etc. Within etc, select Once that is done, create a new folder within etc called firmware. Once completed, return back to the system folder, create the folder called lib. In the lib folder, create a new folder called hw. So your folder should look like this:
Folder Name
-system
--etc
---firmware
--lib
---hw
So far so good? Excellent. Now, if you're in windows you will need to do a few things. Extract the system.ext2 of your donor build and place it somewhere you will remember (like your desktop). Now open up explore2fs, select file, and open image file. Under files of type (drop down), select all files and navigate to your system.ext2 file. You should now see the ext loaded on the left side of the program's workspace. Located is a very small + that allows you to view all directories in your ext2 file. Click that.
You will see several system folders on the left and files on the root. Since you haven't selected a specific folder, in the right hand view, you should see the file build.prop. If you did select a folder (like app) you will see some files. And that's okay too. Get a feel of the program.
Now you will do a test file pull. On the left hand side, select the folder etc. On the right window, you will see several files. We want AudioBTID.csv. Once you see the file, right click on AudioBTID.csv and select export file. Navigate to the donor file folder (or whatever you named it) and place the file in system/etc of that folder. Congratulations you just pulled your first file! But you will need a lot more files. Within the same directory, pull gps.conf, hosts, media_profiles.xml and the ppp folder. Now, navigate to firmware and pull the following files:
BCM4329B1_002.002.023.0360.0362.hcd default_france.acdb htcleo.acdb
BCM4329B1_002.002.023.0436.0439.hcd default_nel.acdb yamato_pfp.fw
bcm4329.hcd fw_bcm4329_apsta.bin yamato_pm4.fw
default.acdb fw_bcm4329.bin
Ideally you should not be able to find htcleo.acdb. You can find it here
http://gitorious.org/xdandroid_leo/q...eo/htcleo.acdb
Now in explore2fs, go to the lib directory and pull these files and place them in your lib directory:
libcamera.so
libcamera_client.so
libcameraservice.so
libhtc_ril_wrapper.so
libmm-omxcore.so
liboemcamera.so
libomx_aacdec_sharedlibrary.so
libomx_amrdec_sharedlibrary.so
libomx_amrenc_sharedlibrary.so
libomx_avcdec_sharedlibrary.so
libomx_m4vdec_sharedlibrary.so
libomx_mp3dec_sharedlibrary.so
libomx_sharedlibrary.so
libomx_wmadec_sharedlibrary.so
libomx_wmvdec_sharedlibrary.so
libOmxCore.so
libOmxVdec.so
libOmxVidEnc.so
libqcomm_omx.so
libstagefright_omx.so
Once those files are pulled, navigate to the hw folder of the system and pull the following files:
sensors.htcleo.so
lights.htcleo.so
Once those files are pulled, you can save your donor files to a flash drive and then boot into your linux distro. Login to superuser in terminal. For fedora, the proper method involves typing in su --login and entering your password you set up. Minimize your terminal window.
Extract the miui (or any other build) to your desktop (the focus is the system folder). Ensure the rom is deodexed and in your own language (if its miui, you will have to apply the proper language translations). Now copy the files you pulled from your donor build and apply it to the appropriate folders (usually a copy and a paste-literally). In this instance there will be duplicate files, overwrite them. That's the point! Do not forget the build.prop file I linked to earlier. You should add that to system folder.
So the files are copied, the next step is to restore the minimized terminal window (the one that is logged in as root). cd to where your system is located (not to the system folder itself). Now you will have to enter the following commands in terminal
chmod -R 777 system/etc
chmod 755 system/bin/*
chmod 755 system/xbin/*
rm system/etc/firmware/default*acdb (if you have sound in call issues)
touch system/etc/ppp/active (If you have latest wrapper and need ppp)
chown root:2000 system/bin/pppd
chmod 4755 system/bin/pppd
chown root:root system/xbin/su
chmod 4755 system/xbin/su
chown root:root system/xbin/hci*
chmod 4755 system/xbin/hci*
dd if=/dev/zero of=system.ext2 bs=1048576 count=256
mke2fs -F system.ext2
sudo mount -o loop system.ext2 /mnt2
cp -rp system/* /mnt2
sudo umount /mnt2
A few words on this that I must bold. the /mnt2 directory may not exist. If not, try mnt, that usually works
Once this is done, you will have a nice system.ext2. The only thing you'd need now is a rootfs, a kernel, clrcad.exe and a startup.txt file. Once that is done, you can test your build out.

Are you sure its the only difference? Are the nand drivers stored only in the bootimg/initrd and not somewhere in the system.img?
yes or no will do for me thx

Is there a way to edit system.bin files, that comes with the NAND builds. I suppose that is where the ROM is. I want to unpack, edit the included apps and repack. How it is done? How the bin file is done. Google does not give any satisfiable links, did a quick search, though...

i am confused
Which explore 2fs do I download? There are 3 different ones one for binary one for code and optional update source code. I am a noob and tired of not having roms I am happy with. I have windows 7 and xp. I realize this will take time and I am good with it everything thats worth anything takes time.

I think you mean system.img not system.bin
You can extract them with the unyaffs.exe or with the unyaffs command under linux. I have written a guide with attatched utilities here
Additionally birksoffsjunk (seasoned WM guru & chef of ChuckyDroid, ChuckyROM, & Dexter) has made a batch program to make this process easier. It's a work in progress & somethings are still buggy so follow the thread
Between the utility birkoffsjunk made & the tutorial I wrote you should be able to successfully edit & run your own build. Hope this helps.

You can extract them with the unyaffs.exe or with the unyaffs command under linux. I have written a guide with attatched utilities here
Additionally birksoffsjunk (seasoned WM guru & chef of ChuckyDroid, ChuckyROM, & Dexter) has made a batch program to make this process easier. It's a work in progress & somethings are still buggy so follow the thread
Between the utility birkoffsjunk made & the tutorial I wrote you should be able to successfully edit & run your own build. Hope this helps.

anyone know how to edit or anything about initrd.gz?

It's an archive that can be decompressed and edited thru linux.

White-Energy use system.bin in his rom
Regarding initr and zimage, there is a guide that you can point me on ?
Thank you

I have only green HTC
Hello
I would like to use Android on my HD2. I was searching and testing many ROMS but I didn´t find any rom which is usable for me. I would like to have a ROM that is without Sense, has Multilanguage support and is on Android 2.2 version.
So I decided that I would make my own.
0) I was reading
HTML:
http://forum.xda-developers.com/showpost.php?p=10291851&postcount=1
and made this procedure.
1)downloaded some ROM from here
2)unpacked this rom in linux with :
Code:
unyaffs system.img
then I got this directories:
Code:
app bin build.prop etc fonts framework lib media usr xbin
3)I downloaded update-cm-6.1.1-N1-signed.zip from CyanogenMod Forum > Downloads > Stable Mod > Nexus One and unpacked. I got : META-INF system boot.img.
4)I copied everything what was described step 0 from directories from step 2 to directory system from step 3
5)I downloaded and copied build.prop from step 0 to system
6) I updated permition like it is described in step 0
7) I created system.img with command : mkyaffs2image . ../system.img
Then I copied this system.img from linux to my windows and put this file in directory in which was different NAND rom. (replaced system.img). After that I flashed my phone and it did not work. Screen was frozen after booting and only green HTC was on display.
Can somebody please help me and give me some advice or some small howto. Does anybody know what can be wrong?
Thank you
Michal Fichtner

I appreciate the guide but damn that is hard to read. It really needs some sort of structure to it, titling proper paragraphs etc.

Hi,
it is possible to combi the dropdown energy widget froom miui and the gingerbread lockscreen into Desire HD Build?
Thats was awesome !
Sorry for my bad english

[Q] Help with building stock kernel

I would like to learn how to build stuff for my tmobile s2. I figured I should try to build the stock kernel first to get my hands dirty. I have been following this guide here: http://forum.xda-developers.com/showthread.php?t=1442870
Unfortunately it is for the Epic Touch 4G, but I think a lot is similar. I have several questions regarding building a kernel for the T989:
1) How can I extract the initramfs from a stock boot.img?
2) The guide from the link above tars a zimage file. Does this need to be boot.img for the T989?
Thanks.

Below I have posted what I have done so far in trying to compile a kernel for the T989, in case anyone else is also learning like me.
I am using Ubuntu 10.10 32-bit
1) Download T989 source code from here: https://opensource.samsung.com/reception/receptionSub.do?method=search&searchValue=SGH-T989 (download the T989 version for TMobile)
2) unzip SGH-T989_GB_Opensource.zip
3) extract SGH-T989_Kernel.tar.gz
4) next you need to get a version of the initramfs. I got it off of my phone using clockworkmod backup (boot.img file) and following this guide to extract the initramfs: http://www.freeyourandroid.com/guide/extract-edit-repack-boot-img-windows
5) Download arm toolchain here (I use version 2010.09): https://sourcery.mentor.com/sgpp/li...09-51-arm-none-eabi-i686-pc-linux-gnu.tar.bz2
6) extract toolchain
7) Setup cross compile script (run before doing compiles) (change CROSS_PATH for your setup):
cross-compile.sh:
BINVERSION=arm-2010.09
export ARCH=arm
export CROSS_PATH=~/android/toolchains/${BINVERSION}/bin/
export CROSS_NAME=arm-none-eabi-
export CROSS_COMPILE=${CROSS_PATH}${CROSS_NAME}
export CC=${CROSS_NAME}gcc
export CXX=${CROSS_NAME}g++
export LD=${CROSS_NAME}ld
export STRIP=${CROSS_NAME}strip
PATH=${CROSS_PATH}:$PATH
8) Compile script (modify CONFIG_INITRAMFS_SOURCE to point to your initramfs) :
source ../scripts/cross-compile.sh
cd kernel
make clean
make mrproper
make msm8660_celox_usa_tmo_defconfig
make modules
make -j5 CONFIG_INITRAMFS_SOURCE=../initramfs
9) The kernel image is in "arch/arm/boot/zimage"
10) *** Question: How do I make the zimage "odin" compatible
This is still not complete (Steps 10 is unsolved). I need to make the build image odin compatible.
If anyone knows of a kernel building guide that exists for the T989 please post here.
Thanks.

You should pm the devs that posted their kernels in the dev section. Im sure they would love to help. Even exchage google talk or google + with each other to get quicker answers.

I noticed you hit up the e4gt thread so I came here to see If I can help. If you have Irc I can walk you thru It all the way. I lost all my data today so my machine is down for building. im on freenode #evervolv ...

interloper, thanks for the kind offer. Please let me know when your machine is up and running. Hope to hear from you. Thanks again.

This is the script you want to use to extract the initramfs http://forum.xda-developers.com/wiki/Extract_initramfs_from_zImage
It works for the E4GT without modification so it should work for you guys without modification.

dtm_stretch,
Thanks for the extract script. The script does not work when I try to extract the initramfs from a boot.img I got from doing a backup with clockworkmod. It only manage to extract two empty folders: "dev" and "root"
However, the script does work when I tried it on a zImage I built myself. With the kernel I built I used the initramfs provided at: https://github.com/bubby323/anomaly_kernel_platform_SGH-T989/tree/master/initramfs
I know I can use the initramfs at the github but I really would like to learn how to get it myself so I can apply to other phones later. The knowledge is more important to me.
Thanks.

I was able to extract the initramfs from the boot.img (cwm backup of my phone) using the tools at this site: http://www.freeyourandroid.com/guide/extract-edit-repack-boot-img-windows
Now my only problem is making a odin compatible (flashable) kernel from the compiled zImage. Is it as simple as renaming zImage to boot.img and then put it in a tar to flash with odin? The only reason why I am not certain is my zImage is only about 5megs while the boot.img is 10megs. It seems like the boot.img is a disk copy of the flash partition for the boot on the phone. Do I need to use dd to copy my zImage into boot.img?
I know I make no sense. Hopefully with this last step I have it all down (at least for creating a kernel, rom is next). Please help a noob. Thanks.

Sorry for not replying sooner, but if you want to create a flashable tar in terminal
Code:
# cd /where/your/zimage/is/located
# tar cvf whateveryouwanttocallyourkernel.tar zImage
or you can just use a zip that already flashes a kernel and swap out the zimages.

I was able to successfully build my kernel and flash it to my phone. I needed to use mkbootfs and mkbootimg to combine my zImage and ramdisk to make boot.img. I will post a tutorial up in the development section and will link it here when I am done. Hopefully it will help all the noobs like me get their feet wet. Stay tuned.
update:
here is the link to the guide: http://forum.xda-developers.com/showthread.php?p=22941057#post22941057

ODIN .tar
I advise all of you to learn bash scripting. With bash scripting or pearl you can automate this entire process. Also create a cheat sheet text document with long but common commands, git command reminders and things like that. These commands should create your ODIN .tar file. First cd to the directory the junk is in then:
Code:
tar -H ustar -c factoryfs.rfs cache.rfs modem.bin zImage boot.bin recovery.bin param.lfs sbl.bin > myOdin.tar
That makes the tarball
Then:
Code:
md5sum -t myOdin.tar >> myOdin.tar
That does the MD5 sum
Then:
Code:
mv myOdin.tar myOdin.tar.md5
That sign the tarball with the MD5 sum
You should be able to ODIN that .tar. Now, for the first command you can replace whatever files you want tarred with what I put. If you only want the modem.bin specify that only, etc.
Another word of advice is to find helpful helpful Nautilus scripts to ad to the right click context menu for time saving simple operation. Google it and you find several good resources. Also, if you look, there are Nautilus scripts that can be added to zip and sign .zip and .apk files to make that faster and easier.
Be careful out there and good luck.

[Q] How to pull ramdisk.img from xperia play?

ive been goggling all day with no luck, to a experienced dev in the business of making kernels i bet this is a easy one but how can i extract my ramdisk from xperia play (Preferable in windows)? I hear something about Boot.img so i pulled that out via ADB but i also read that theres a zimage or something where exactly is this file?
im really trying to avoid linux

First, that "boot.img" is kernel+ramdisk inside one file.
I use Android Image Kitchen
http://forum.xda-developers.com/showthread.php?t=2073775
for windows to unpack boot.img
You'll get ramdisk and zimage from it.
Make your changes to ramdisk and repack.
Keep in mind that sometimes ramdisk is packed (it is because there are multiple ramdisks in kernel - for normal boot and for recovery(s))
It can be confusing because it's packed ramdisk files inside cpio packed file inside img packed file...
I don't know exact command how to extract boot.img from phone itself, it is done from adb shell, something like
dd /dev/block/mtdblock3 > /sdcard/Boot.img
Also, as you, i am windows user, but some things can only be donne in linux (like compiling kernel), but somehow i managed to install ubuntu13.04 in virtualbox (it took me two weeks to set it up for compiling). It can be pain in the a$$ to set it up and i needed to install teamviewer to access files inside it, but once it's done, all i do is copy paste commands in terminal window...

Unable to build kernel from source, what i'm missing?

Hello to all!
I'm an heavy oneplus user, currently with Nord, but i'm try to use my old but Gold Oneplus 3 to run Klipper+Moonraker+Fluidd.
Klipper side everything is perfect, still remains one big issue: there is no kernel compiled for OP3 which has USB_SERIAL_CH341 driver enabled.
I'm trying to build but without success. Here is what i've done under Linux Mint latest version.
First of all i've installed a lot of packages, i cant remember all because i used various guides since initially i was not able neither of finish compilation.
Then i've downloaded:
kernel source: https://github.com/lin16-microg/android_kernel_oneplus_msm8996/tree/lin-16.0-mse2
from this ROM thread, which is the rom im still using: https://forum.xda-developers.com/t/...ened-lineageos-16-0-for-oneplus-3-3t.4034869/
initially i've tried to use EVAgcc toolchain, but it was impossible to finish to build. Then i switched to AOSP toolchains:
32bit: https://android.googlesource.com/pl...inux-androideabi-4.9/+/refs/heads/pie-release
64bit: https://android.googlesource.com/pl...64-linux-android-4.9/+/refs/heads/pie-release
With Them i was able to compile from source, but before doing i modified the file called "lineageos_oneplus3_defconfig" by adding "USB_SERIAL_CH341=y" just under the "USB_SERIAL=y" in order to have the serial driver compiled and loader (if i have understood right?).
to build i've used from inside kernel source cloned directory:
>make clean
>make mrproper
>ARCH=arm64 SUBARCH=arm64 CROSS_COMPILE=googletoolpath/bin/aarch64-stuffs- CROSS_COMPILE_ARM32=googletoolpath/bin/arm-stuffs- make O=out lineageos_oneplus3_defconfig
>ARCH=arm64 SUBARCH=arm64 CROSS_COMPILE=googletoolpath/bin/aarch64-stuffs- CROSS_COMPILE_ARM32=googletoolpath/bin/arm-stuffs- make O=out Image -j2
in this way i've obtained an Image (not a zimage since with zimage returned error).
Then i unpacked the stock boot.img with Android Image Kitchen, substituted boot.img-kernel file (which is an archive..?) with the compiled image renamed.
Finally i repacked everything.
Tried to flash the repacked boot img but no boot, the phone returns to fastboot screen.
I've noticed that my newboot.img is around 25mb insted of around 12mb like the stock one present in the Rom.zip
Probably the error resides in how i've managed to unpack and repack the kernel image..
Do someone see some heavy error which can cause the problem? What can i try?
From a side, as automation engineer, i want to learn and try to do it by myself, but on the other side, if someone is able to compile it for me with serial CH341 driver enabled a beer is assured.
Thanks all to have read up to now and for any advice

not sure that's important but you forgot to gzip kernel before repacking. I recommend to compile with configuration of running kernel from device /proc/config.gz first.

I've to try because it is not gzipped by default, the problem is that I don't found all in one scripts or config file as the one mentioned by you. I would never thought that rebuild a kernel were so tricky.
