View 1 RepliesI try to understand android boot sequence on my JB (under CM10). I found some docs and there should be specific partitions (boot, recovery, system, cache, data).
My understanding of the boot sequence is now:
A) normal boot:
1) Power ON ->
2) bootloader ->
3) boot-partition where i flashed the kernel aka boot.img ->
4a) system-partition with the OS (libs, UI, etc) where i unpacked over CWM my customROM.zip ->
4b) data-partition, where i unpacked google-apps.zip and installed all the apps ->
4c) cache-partition with user data
B) recovery boot (adb reboot recovery):
1) Power ON ->
2) bootloader ->
3) recovery-partition with CWM where i may unpack all the .zip stuff to proper partitions, or restore from sdcard, etc.
Is this correct? I wonder, because i didn't installed CWM into recovery-partition. It cames from install of CM10 (fastboot -i 0xfce flash boot boot.img), so it must be in boot-partition and not in recovery?
So, next confusion: i looked up to /proc/mtd and i don't see neither boot nor recovery partition here:
Quote:
# cat /proc/mtd
dev: size erasesize name
mtd0: 19000000 00040000 "system"
mtd1: 00600000 00040000 "appslog"
mtd2: 06580000 00040000 "cache"
mtd3: 1a400000 00040000 "userdata"
I did a backup with CWM and loocked the data. There aren't boot, and recovery backups:

So, i think i didn't understand the boot sequence and partition schema corectly.
I am trying to do some low level performance testing related to device processor cores through adb which I feel it is affected by Android background services and system stuff.
As I know that the Android boot sequence stages are as follow:
1.Execute Boot ROM code.
2.Execute the boot loader.
3.Load the Linux kernel.
4.Launch Zygote, which initializes the Dalvik VM.
5.System server which loads the Android system.
So my question is how can I interrupt this sequence to force it stop on stage 3 to load Linux kernel. This can implement my intermediary performance testings before loading again Android system.
Does Fastboot or Clockworkmod recovery can load my device to a kind of Linux kernel?
Instead of seeing the boring old Android logo or my service provider's logo, I'd love to see the standard text-based Linux boot screen that shows the status of all the hardware and configuration info as my phone boots. My current phone is an HTC EVO 3D running Cool ICS with Sense 3.6 and Revolutionary CWM.

Can the Android OS boot directly into that application so that only a certain application launches after boot. I'm building a client some custom software and I'd prefer to use one of those Archos 5 MIDs than a Linux netbook.
View 2 Replies View RelatedI went to reboot my Droid because it was lagging a little and when it came back on it go stuck at the Cyanogen boot screen. I pulled the battery, put it back in and held the X to boot in recovery and my recovery won't come up either. It just skips right to the Motorola M and if it doesn't get stuck there it goes back to the Cyanogen screen.
I haven't made any changes to the phone at all so I am completely puzzled on why this is happening. I obviously can't take it back to Verizon since its rooted so if there is a way to fix this I really want to because I love my phone and my wife will kill me if it is screwed up.
huawei u8860:
i compiled a kernel from the sources kernel-3.0.8-U8860-IcecreamSandwich.tar.gz .
on virtual box ubuntu 10.04 (oracle java 1.6.0u33 )with
Code:
gcc -v
x86_64-linux-gnu
gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5.1)[code]......
I tried installing Tranquility and must have screwed something up because now my phone won't boot past the Motorola Logo. It's been sitting here like this for about 15min and I can't even boot into recovery by holding the power and home buttons. I don't know what else to do now. Idk if my phone is bricked but even if it is don't I need the SBF file to unbrick it and I can't find that file any where. I did a nand backup or whatever before doing any of this so hopefully that can help me. What should I do now?

View 2 Replies View RelatedI'm trying to guess what are the files that contain the low level code of the boot.img/recovery.img images. I tried modifying the .S files in the sub folders of "/bootable/bootloader/legacy/", but after a re-compilation the boot image are exactly the same as before my edits to the file(s) (Checked with shasum before & after the re-compilation). Also, I'm trying to avoid a "make clean", because a full compilation takes me about 3.5 hours

View 1 Replies View RelatedI have a number of app's that seem to start and run at random.
I still want these apps on the on phone, so don't want to uninstall, just want to be able to choose when they start up - rather than them starting at random and running in background.
Some of the app's running:
Music
Footprints
Stocks
FM Radio
Juiceplotter
Fake-call-me-Pro
Is there an APP similar to AUTORUNS (which I use on my Windows PC) that lets me choose what programs run at boot?

View 5 Replies View RelatedI have a BroadcastReceiver which never enters onReceive(), so to debug I created a bare bones project with a simple BroadcastReceiver and still it never gets the BOOT_COMPLETED intent (see manifest below).
I do see a lot of warnings/errors in my Eclipse log (filtered and after manifest) which didn't seem to cause issues before, but maybe I have a bad install of the emulator? I have all the latest SDK and plugins. I also noticed that when I run the emulator I always get "Waiting for" popup for either Alarm or MMS.
The debugger attaches normally for my main Activity, it's just this "boot" receiver that never seems to start. I've tried using "com.boottest.BootReceiver" instead of".BootReceiver" to no avail.

From the service I would like to receive the intents such as boot completed and screen off and on. Currently I am using a BroadcastReceiver to get the boot completed intent and then on starting a service to receive screen on and off intents. But I would like to remove either the broadcast receiver or the service. Any inputs.
