General :: Android Boot Sequence And Backup / Access To Boot / Recovery Partitions?
Oct 4, 2012I 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:
Quote:
# ls -lha /sdcard/clockworkmod/backup/2012-10-04.18.49.55/
d---rwxr-x 2 system sdcard_r 4.0K Oct 4 18:56 .
d---rwxr-x 3 system sdcard_r 4.0K Oct 4 18:49 ..
----rwxr-x 1 system sdcard_r 1.6K Oct 4 18:54 .android_secure.vfat.dup
----rwxr-x 1 system sdcard_r 54.6M Oct 4 18:55 cache.yaffs2.img
----rwxr-x 1 system sdcard_r 360.2M Oct 4 18:53 data.yaffs2.img
----rwxr-x 1 system sdcard_r 212 Oct 4 18:56 nandroid.md5
----rwxr-x 1 system sdcard_r 214.6M Oct 4 18:51 system.yaffs2.img

So, i think i didn't understand the boot sequence and partition schema corectly.
General :: How To Interrupt Android Boot Sequence To Force It Boot To Linux Kernel Only
Sep 12, 2013I 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?
General :: Can Android Boot Logo Screen Be Configured To Show Linux Boot Logging
Jun 13, 2012Instead 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.

Motorola Droid :: Won't Boot Past Cyanogen Boot Screen
Oct 30, 2010I 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.
Android :: Can Boot Into A Single Application On Boot
Oct 24, 2009How easy is it to make an application that's just a wrapper around the browser? 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.

May 24, 2012Is there a way by either an internal file or maybe an app to be able to track the boot log sequence of an Samsung Epic Touch (4G) Sprint (Or any other Android phone for that matter) . so if I have an error or an app is acting up I can tell which app or where in the boot up sequence there is a problem and what is causing it.
Now I have to uninstall the latest apps until I find the one that is causing a problem.
Also is there a way to for lack of a better word to (safe mode) or similar?
General :: Evo 3D On Boot Loop
Mar 24, 2012I recently just rooted my evo 3d sprint with the the boot 1.5 and everything went well. I decided i wanted to overclock my phone so i followed zeemaxs way. Before going into the overclock procedure i decided to do the the RCMIX Evo 3d kernel v. 2.2.3 first so i would have better results when done with the overclock procedure.I boot-up the kernel through the recovery mode on the phone butit failed to load so i just rebooted. After that my wifi and 4g stopped working. So i downloaded an app on the market called "flash image GUI" which lets me flash the kernels through the app. I flashed the RCMIX kernel and rebooted and now im stuck ima boot loop. I COULD just go back and back up to my old rom and settings etc but the problem is i dintmake any kind of back up or recovery i think.

General :: Phone Won't Boot Into Any ROM
Apr 20, 2014I rooted my Samsung Galaxy S4 (SCH-I545), then I decided to install a custom ROM since the default TouchWiz rom is slower than a turtle stuck in a pile of wax. I installed Safestrap 3.71 (TWRP v2.6.3.1) and by mistake flashed my stock rom. Now my phone won't boot into any ROM since that is corrupt, but it still boots into recovery (that's a good thing I suppose). I have tried a number of Safestrap compatible roms (omni, cm, beanstalk) but they either end up giving me a black screen or a very weird looking pixelated blue/cyan screen. I have to remove the battery to reboot my phone. I tried using adb to wipe the data aswell but nothing works beyond recovery. I have to rely on adb to push and pull data to and from the phone.

Went through all the steps to flash Rom manager as the recovery but I cannot get my recovery to go to CWM, it just keeps going to the stock android recovery.

General :: Samsung Exhibit II 4G Won't Boot Up?
May 30, 2012I have a Samsung Exhibit II 4g phone. Yesterday I powered up the phone and it went to the start-up screen that displays the phone's logo: "Exhibit II 4g," and it froze on that screen. I tried to remove the battery to reset it. I looked at some online forums about "brick walls" and tried to remedy the problem with those. I think I tried to reset to the factory configuration. I tried using the Heimdall One Click, Odin, Z image, Winrar, etc,etc. I just followed the steps because I thought that reseting the phone to its factory default setting would correct whatever was causing the phone to freeze. I am a total novice with this stuff, what "flashing" or "rooting" mean.

General :: Can't Boot Into Recovery - Karbonn A6
Apr 10, 2014I have a Karbonn A6 phone given to me by my friend because it was locked. It's asking for gmail user/pass but he doesn't have it. I tried to boot into recovery mode using Power+Volume Up button but all I get is a white triangle with an exclamation mark in it. I can't seem to go beyond that. USB debugging was perhaps not enabled unless it was enabled by default. There is no camera button, only power and Volume Up/Down. What do I do?
I just need to get this phone working somehow. Is there a way to use a computer and a USB cable to get it running?

General :: Arnova 10D G3 Tablet Won't Boot
Jan 13, 2014I just got a Arnova 10D G3 and it doesn't boot. All I get is the "Arnova" logo on a black screen. I bought it on a refurbished condition, it was a pretty good deal so I am ready to do any risky procedure to make it work since I don't have much to lose.
I downloaded the latest firmware from the official website but I am unable to use it because I can't access the recovery mode.
How can I make it boot?
I am now able to access the recovery mode (power + vol up) but the tablet keeps rebooting after loading this mode. I don't even have a menu.
