[Q] Some Questions - Milestone XT720 General

stupid/sily questions:
APK related
if I try to delete a single file or apk in an android system, will it delete related files also?
Port related (ASOP/CM6/CM7/Custom ROMs/etc)
I know that the majority of XT720's kernel is 2.6.29..., anyways, why I am seeing 'Android version of 2.3.5'? and getprop value of '[ro.build.version.sdk]: [10]?..., are these valid?
I still have many questions that I would like to ask but for now, this will do.
Please enlighten me, I'm still starting to learn 'Android', any feedback is appreciated..., be it good or bad
best regards,
dabiano

Actually all the kernels are 2.6.29 because that's all Motorola has released--and because of the signature checks we can only use official Motorola kernels (except for fastbooting). That only applies to the kernel, though. Those ROMs have newer userspaces. E.g everything else (GUI etc) uses newer code. Even Motorola's 2.2.1 for Motoroi used 2.6.29.

thanks for the reply
I'm still trying to grasp it all in my head about porting/compiling android (ASOP/CMx/etc...)
So in short, we can technically upgrade the userspace/api level of the entire android system even if the kernel stays the same?
also, you are saying that we can use another kernel if fastboot is used?, why not trick the bootloader to use a kernel that comes from a 'false' fastboot?, I may be wrong though ...

That's right. I'm not certain but what I've gathered is the biggest kernel changes happened before 2.1 (which changed process management). I think it's been tweaked subsequently, but it may not be such a big deal. Additionally, there is another option--what I would call "kernel live surgery"-- skrilax_cz and nadlabak on A853 have been doing a lot of that lately--making modules that replace functions inside the kernel to replace bugs and add features.
And yes we can boot custom kernels using "fastboot boot", but I don't think anyone currently knows whether it is possible to trick fastboot to work without USB. It depends on how fastboot has been implemented. A853's seems to be the most studied bootloader, but "fastboot boot" doesn't work on A853.

Thanks for the info you shared Mioze7Ae

{KERNEL-SOURCE} GoDmOdE-EVO-2.6.29 {Make Shift Kernel}[SENSORS-LIGHTS-PANEL-FIXED]

THIS SOURCE WILL WORK ON ALL CURRENT HTC EVO'S!!!
i found the board files for the EVO a while back but wanted to wait til we at least had the release RUU to release it. now the actual kernel itself isnt a EVO kernel. its actually an Incredible kernel source with the EVO board files in it. that said i had to mod the board files a little to get it to compile. anyhow link below and remember to fork as it helps github and everyone. thanx

THIS IS A UPDATE.ZIP THAT CAN BE USED WITH FRESH ROM, TO BOOT THIS KERNEL WITHOUT WIPING. PLEEEEEESE DO A NANDROID BACKUP BEFORE FLASHING THIS UPDATE.ZIP. SO U CAN JUST NANDROID RESTORE UR DEVICE BACK TO NORMAL AFTER UR DONE PLAYING . ANYHOW CAMERA IS NOT WORKING AND THERE SEEM TO BE WHATS THOUGHT TO BE VSYNC ISSUES. ANYHOW ENJOY!!!

now i see the catch 22...sorry im new to all this and dont have an EVO to experiment with...
could this kernel be combined with the standard ramdisk into a boot.img, packaged into a signed update.zip and installed through the stock recovery?

No. You can't flash anything worthwhile until the phone is rooted. Once this happens expect this forum to explode.
No we need root and the ability. To flash a custom recovery. Basically. The catch 22 is we need root before we can do anything custom
By flashing an updated NBH, doesn't that overwrite both the Kernel and the OS on the NAND? If so, couldn't we replace the Kernel with one with root, and also provide for our own (AOSP, etc.) builds of Android?
Essentially, I'm wondering what the breakdown process is for recovery. The bootloader (Power + Volume on boot) is stored on the ROM, so regardless of "bricking" your device, you should always be able to get back to the bootloader to recover, correct?
If that's the case, what stops us from simply building an NBH with the current (locked) Kernel, but with modified system files for our own ROM?

we're thinking alike here. some of this terminology is new to me and some isnt. hopefully this makes sense. im gonna reword but ask the same question as above (at least i think same question) plus another question. im doing a lot of research and tryin to word things correctly...
this might be the same question as above, are we able to trick the supersonic RUU released here into loading our own rom.zip file (NBH)? (we were able to do this with the samsung moment)
if not, are we able to use the fastboot-bootloader mode (samsung moment doesnt have this) to install a custom recovery? if so, we are then waiting on a custom recovery to be developed?
I think we are heading down the same path.
My understanding is that flashing a new "ROM" via NBH will replace both the Kernel and the OS (Android) files on the NAND, as both live there. The only item that lives in the ROM itself is the bootloader, which should always persist. With this understanding, even if you totally destroy your Kernel and/or Android OS, you should always be able to power the device to bootloader mode (Power + Volume) to flash (and therefore replace/restore) a new Kernel/OS to your phone.
If that's the case, then root access isn't necessary. All root access will allow us to do is some fancy side operations, like running a ROM (OS) manager inside Android--and who really wants to do that? Most of us want to be able to load a single custom build of Android, optimized and designed the way we want, right?
My thought process is this:
HTC should be releasing the EVO Kernel source on developer.htc.com by the official launch. With that, we can compile the Kernel ourselves (if we can't otherwise find it compiled) and theoretically bundle that with our own OS compilation of Android into a .NBH. This .NBH could then be flashed via the bootloader, replacing both the stock OS and the Kernel with what we've bundled.
This would seem to mean we wouldn't have root access, but we wouldn't need it, as we could simply update the OS files, build an .NBH, and provide it to users to flash. This could mean that custom distros would be a single contained file--one file to flash and that's it, you're updated.
Thoughts? Is this accurate?
If this is the case, we should start looking at the Kernel and the .NBH format rather than obtaining root, because once we understand the .NBH, we can load whatever we want (including a Kernel with root access, if desired.)

ok.. the bootloader isnt gonna let us flash anything that isnt for the phone that ive heard of at least. the bootloader is only gonna let us flash rom.zips signed by htc unless we have a engineering spl. if we had that we could fastboot whatever we want. but it is also my understanding that the new engineering spls will not let us flash to certain major partitions (ie rocovery, and boot) anyhow this i think was an issue for the desire that modaco rooted and he found a way around it. we need a recovery for sure. as starting a new with no backups and such would be nothing more then a pain. we should focus i think on obtaining a engineering SPL from someone nice who wants to hook us up or a exploit of some sort. we need to gain read/write access to system, boot and recovery partitions. we do that and we can do what we want with the device. were not gonna be able to just flash a kernel, boot.img, system, or update.zip thats not official without the ability to gain access to the recovery partition.
in an exploit we would have root user status and we would have write perms on system at that point we could possible add flash_image to bin, chmod it and use that to flash a new recovery. write access is all we need. if ur idea was possible all we would need to do is flash a distro with root access and then flash the recovery partition with a custom recovery. a custome recovery will give us the ability to flash, backup and restore whatever we want. so long story short we need root user status in any event so we can gain access to recovery partition.

[ROM] CyanogenMod 6.0rc1-coburnrom - Milestone Port project

Project Description
This is a project to port the Droid version of CyanogenMod to the milestone. While the Droid and Milestone devices are twins, they are CDMA and GSM respectively. Hacks include not flashing the boot image provided by the CM Droid package and some GSM configurations.
Status
CyanogenMod 6 RC1 (with CoburnROM hacks) will flash successfully, however it will refuse to boot (possibly due to incompatible stock kernel or that the milestone doesn't like unsigned ROMs). So far, flashing works from koush's ClockWorkMod Recovery and Open Recovery 1.14. When rebooted, the device hangs on the M Boot logo.
Downloads
PoC/RC #1: Download from my blog, Geek In The Family - 75MB.
What you can do
Pretty much this ROM is currently a playground, if you want to have a poke around, download a copy of the above versions of the ROM and extract it, and then poke around and see what makes it tick.
Other notes
Space saved for future use.
Cheers!

Good luck man, I really hope this happens
You should check with the guys on and-developers.com, and their IRC channel #milestone-modding on Freenode for any progress on the bootloader
Hacking the bootloader is impossibile on our Milestone, the TI OMAP chipset runs in High Security mode and for switching to General Purpose mode you have to desolder and resolder the OMAP chipset on your mainboard, soldering the right pins for enabling the GP mode.
Anyway, 2ndboot can make us able to boot a different kernel (for now GSM modem is unusable, so we can't use the phone with the new?y booted kernel) and this is the way that we'll take on the Milestone for using a custom kernel.
No custom ROMs. Or at least not this way.
We'll NEVER be able to boot this ROM.

My my, that's negative. I do know about the custom kernel via kexec/2ndboot trick.
Nothing is impossible to be hacked, it's a matter of time and blood, sweat and tears. As Paul from MoDaCo stated, nothing is impenetrable.
I'll get this ROM booting, even if I have to wait a year or two before the Boot loader is hacked or a proper method is working.
Good luck to you. I commend you for your efforts.
After 1 year waiting for the bootloader to be hacked...I am slightly skeptical. However, now that the Droid X has been released to the masses with the same locked bootloader, we might get some fresh eyes to look into this matter.
I would be happy enough with a custom kernel running on 2nd boot ;-)
SenseUI Mod
Hello, You might try using the mot_boot_mode file, which is also used with the SenseUI Port for the Milestone, I guess that would make this boot too? If I'm right, this is the boot sequence:
This is what I'm talking about:
"the ramdisk is located in /system/ramdisk.tar folder, it all starts here.
the ramdisk is opened by /system/bin/mot_boot_mode."
You should download the SenseUI Mod and analyse it's way of booting.
Good luck!

the problem is not about being negative but you are facing it the wrong way .
the problem here is to hack the thing not to port an already existing mod .
Once the bootloader is bypassed they ll be hundreds of real ROMS .
Anybody can pretend at porting there own roms it is completely IRRELEVANT since it wont be possible until its hacked.
you said it 'even if I have to wait ' well there you go do like thousands of others and just wait . BUt please dont pretend at anything else , thank you .
I am actually porting the ROM to the Milestone, in case if you're concerned that I'm lying. Check my twitter for progress reports.
@Mikevhl we may have a hope if we try that! Thanks for the recommendation!
Also, kexec is working. However, instead of rebooting Android with the Droid CM6 Kernel, it just reboots the phone instead. I'm working on a possible fix for that, thank Kiljacken for compiling the kexec module.
So you're not going with that 2ndboot method?
In any case, my eyes are glued to your twitter account

As I said, it IS possible to skip the BL checks, and it's fully hackable...but...I know.... you don't want to resolder your OMAP....
if this mod is "Droid" based, you need to make many modifications to the startup..
the Droid is in no way protected, where Milestone has GSM radio protected, and specific drivers required to open it, which for now only opens when using the original "init" process of a milestone.. the "init" from droid disables radio completely..
but take a look on how i got the senseui port running.. i got the froyo partly running the same way, so im sure my solution used in senseui mod will help you along to make it work...it just requires some debugging and "adb logcat" so you at least can see what happens at startup..
why not work together dexter? i think this may help out in particular cases

I'm very interested in your work since it seems that we will never see an official 2.2 from Motorola... I don't know if we are going to have the new update, here in France (2.1 update 2).
Well, I just have a question. On a french forum, someone posted a method to downgrade the ROM of the Milestone by implementing the right version of the bootloader in it, I don't know if I very clear. This member had some major problems with the 2.1 update so he decided to downgrade to 2.0.1. However he wasn't able to do it because his Milestone was using the 90.78 bootloader while the 2.0.1 rom was using the 90.73 bootloader. Eventulally, he managed to install the 2.0.1 rom on his Milestone by putting the 90.78 bootloader in the 2.0.1 rom.
So my question is : will it be possible put a bootloader in a custom rom in order to make it boot on the Milestone ?
(I would give you the link for the topic on the french forum once my account si verified)

Actually this is a wrong assumption. HS chip cannot be turned to a Generag purpose.
For those who are interested, here is kexec.
Devs should know the drill, insmod kexec.ko etc etc.
Originally made by Kiljacken (compilation, etc), shared by me.
As for the Android 2.0.1 on Boot Loader 97.73, he may have just made a custom update zip that nukes the system partition and installs 2.0.1 on the device.
Also, I updated my Boot Loader to 90.78ch, which is the XT702 Boot Loader - no bricks. Yet.

D2G Security

Hello wonderful people of XDA! This is my first post, so I apologize in advance if I am asking obvious questions.
So everyone is talking about the "locked" bootloaders present on several of the new Droid phones, including my beloved new D2G. This has been cited as the reason that the bootloader, recovery menu, and android kernel on these phones cannot be replaced with unofficial code. I was wondering if anyone here knew the exact technical details of the security systems that actually make up this so called "lock".
One thread I read vaguely mentioned RSA keys, so I can only assume that something somewhere is signed. Is it the typical setup, with a bootloader that is signed with a key that is burned into the CPU, and a kernel that is signed with a key in the bootloader? Clearly the code on the /system partition is not signed, since I was able flash a custom ROM over it (not to mention install the bootstrap recovery).
Also, how much control does a root process really have? If it is possible to inject root code into the boot process just by modifying some things in init.rc (as the bootstrap recovery does), then shouldn't it be possible to manually load whatever we want into memory after that point, including a new kernel? If so, then couldn't we leave the (presumably) signed stock kernel in place, put our kernel in /system, and write some root code that copies it into memory and executes it (without checking any sigs)?
Forgive me if I have no idea what I am talking about. Like I said, I am new to the forum, and I just got my first Android phone a few months ago.
Thanks!
A guy by the name of Matthew Veety (aliasxerog on droidforums) is working on a kexec module to reboot a custom kernel after all the security checks. He has gotten it to boot, however, most of the hardware doesn't function as he needs drivers built for the new kernel. For now the project is focused on the DX, but they have mentioned the D2G as a "planned project."

Hi,
Punmaster did you find any more information concerning the locked bootloader. Any ideas to put another kernel?
If i understand well, the roms can only modify the application layer.
You seem to know linux dev, maybe you can help me with the usbnet problem?

[A510][Kernel]Development Questions

Hi Folks,
I already spent some years in customizing Linux kernels and in the last time I was already playing around with Android devices and the possibility they offer to boot customized kernel. Now, thanks to NoThrill, we have a working CWM and my interest rises again. I already compiled the Acer Kernel Sources but I got into trouble booting it. Few months ago, I did the same with a lenovo IdeaPad a1 and it should be possible on the A510 too to boot an outside kernel using the command fastboot boot kernel ramdisk.gz. Problem is, that it does download and boot the kernel - but then it returns to fastboot mode instead of booting android. First I thought, it may be due to kernel errors but it does the same if I am using the stock kernel or the boot.img provided by working ROMs. So my questions are:
Is there any possibility to test an experimental kernel without flashing it first? Do I understand correctly, that it is relatively safe to flash it to the boot partition as long as recovery keeps untouched?
What exactly does the (unexplained) command fastboot continue? I thought it may be used to continue booting process with a downloaded kernel, but unfortunately it seems like it does just the same like a normal reboot ...
Simply pack the kernel into a boot.img and flash it to the /boot partition. If something goes wrong, simply reboot into recovery and flash your original boot.img back. Recovery will always work because it uses its own kernel and therefor is independent of whatever kernel you flash to /boot.
A word of warning though: The Acer kernelsource contains code that could brick your tablet. That needs to be fixed before you experiment any further.
Nevertheless, any work done on the A510 kernel is always encouraged :good:

THAT is something really easy you know..
but if it's something that you agree, i can upload it to my git if you don't want to use time for that.
i can clearly state about the source and then.. work can be shared and commit done.
otherwise, yu have to set-up a free account and follow this :
https://help.github.com/articles/create-a-repo
it would REALLY help you know

Are MediaTek 6563 and 6567 ROMS interchangeable?

I have an RFinder B1+(14) that works fantastic, it has the 6567 chipset. I also have an RFinder B1 Classic with a 6563 chipset that will not boot into Android 8 on the way, and the ROM has not been easy to find.
I suspect they are NOT compatible, but if I did flash the older radio with newer firmware, I'd be able to reverse the damage as long as I didn't overwrite the preloader.
If the two are, in fact, compatible, it would save me some time.
Are they compatible?

I have an RFinder B1+(14) that works fantastic, it has the 6567 chipset. I also have an RFinder B1 Classic with a 6563 chipset that will not boot into Android 8 on the way, and the ROM has not been easy to find.
I suspect they are NOT compatible, but if I did flash the older radio with newer firmware, I'd be able to reverse the damage as long as I didn't overwrite the preloader.
If the two are, in fact, compatible, it would save me some time.
Are they compatible?

Not without porting them from one to the other, "IF" the sources to do so are available(either stock firmware for the two devices or at least the stock source code for the device the ROM will be flashed on.
I have tried without success to compile software. Of course it can be done, I just haven't got the hang of it (I need to learn though).
If there are other things I can do, learn, etc from this thread, I'm all ears. If not, thank you for the info.

There really isn't a 100% all in one get it right the first time guide out there. There are lots of guides that give a general idea of how to port stock ROMs but it will still require trial and error to iron out the details. Do some research to see if there are any specific security features preventing the ported ROM from flashing/booting then see if there are any tricks to bypass those specific features. You may need to unlock the bootloader and dig into trying to modify the bootloader.img located in the copy of your devices currently installed stock firmware file(or the last "official" firmware that was installed on your device before you tried to modify it).
