I 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.

I extracted the system.img(ANDROID partition) following this guide on windows: Creating a ROM dump of your MT65x3 device (easily found by searching google, since I can't post links yet)
I then copied the system.img over to linux(ubuntu 12.10).
opened terminal and invoked the command below to see the type of image.
mkimage -l system.img
Code:
Image Type : Davinci UBL Boot Image
UBL magic : 00720019
Entry Point: 00730065[code]...
Code:
Bad magic
how to unpack this type of image or convert it to a raw image so then I can mount it?
I have a Pandigital Star Media Tablet and I am stuck on the boot image and it will not do anything else except boot into stock recovery and turn off. I am able to provide anything you need to possably fix this.
Heres a list of root programs installed:
-z4root
-Superuser
-Titainium Backup Pro
- LCD Density Changer
- Root toolbox
Heres the backups I have:
-Titainium full backup
-Pandigital Backup data
-ADW launcher settings and homescreens backup.
I have probably bricked my Huawei Vision by rewriting boot image.
However, I can connect* it to PC and it sees my phone as "Huawei Handset" (same with Windows and Linux). But Windows misses its drivers (non-bricked phone worked); Linux seems to work. No OS can connect to it using default (downloaded) ADB, nor Fastboot, nor SoftwareUpdateTool.
Its PCI ID is 12d1:c002.
How could I reflash it? I would prefer the ways without disassembling the phone.
How to boot the phone, so you can connect it to PC:
1. turn off my phone completely (vol up + power for 10 seconds - release power for a seconds and repeat it once again)
2. prepare USB cable, so you can connect it in few seconds
3. hold vol down + power and after ~1s, connect USB cable (still hold vol down)
4. when Huawei logo appears, release both buttons - your phone is connected now
I just extract the boot.img file using cygwin android kitchen in advanced option the option 12 but nothing logo.rle ... i just read some thread here [URL] .......
View 4 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.
So I have looked around xda etc. Cant find a simple answer (hoping there is). So long story I am on a rooted Evo. I was trying to flash cm6 via rom manager. I kept getting error 7's. So I found the PC36IMG.zip followed the directions. I am now in bootloader. Tried (many times) to run nandroid. But it gives me the error while flashing boot image for all 3 backups.

View 4 Replies View RelatedI am trying to put a custom boot animation on my moto droid 1. I have root I have done it before and I am using froyo. My big problem now is that I tried putting a different one I downloaded on and it worked. So I need someone to tell me whats wrong with the one I made, because I am out of ideas. I have compared size, resolution, ppi, bit depth but for some reason my images are way bigger files. The sequence was created by using virtualdub to clip a section of an animated short, then exporting an image sequence as png.
But I've fed the images through gimp and an image resizer. The frames are only some of them because I went through deleting every other frame a few times to cut down on the total size. The file is too big to attach here so i put it on my web space at:
http://www.freaksed.com/stuff/bootanimation.zip
I am using the patch that lets me put the files in datalocal and be named bootanimation.zip. it works I've tried with other animations like I said.
I have a Nexus one and I have made a bit of a mess of it when loading a custom rom. Previously I'd rooted (without unlocking) the stock (2.2) rom before loading Cyanogen 6, later Cyanogen nightlies and finally eViL-NXSense-v1213. I was rather enjoying the last one but had severe stability issues which I think was due to using Titanium Backup and restoring data. I was in the process of re-imaging to eViL-NXSense-v1213 after clearing the SD card, data and various caches when something seemed to happen to the recovery image. I can get into the boot loader but if I select Recovery it shows the Nexus One logo indefinitely and doesn't respond to the power button being pressed, the same happens if I turn it on from cold.
Is it possible that the recovery image has somehow been corrupted? If so what can I do to restore a recovery image that will enable me to install a custom rom. I would prefer not to unlock the boot loader but will do it if necessary.
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 9 Replies View RelatedThis is to change the motorola logo that you see when you boot your phone to a custom image. This is separate from the boot animation seen afterwards.Tools/files you will need:
1) RSD Lite
2) droid sbf
3) SBFCodec
4) Photoshop (or paint, or whatever drawing program)
5) Hex editor (frhed is free and very easy to use)
NOTE: I do not use sbf-recall because it complains about needing version 1.3, so I use SBFCodec instead.Steps:
1) Run SBFCodec and open up the sbf file. This will extract all the smg files and header files.
2) Using photoshop, create an image that is 480 pixels wide and 182 pixels tall. Each color should be assigned 8 bits (1 byte), or in paint, just make a 24 bit bmp file. Mirror the image, making the left become the right, and the right becoming the left. Save as a bmp file (photoshop method).
3) Using a hex editor, open up your image and erase the first 54 bytes of data. (and possibly the last 2 bytes of data if you used photoshop. the number of bytes remaining should be exactly 262,080) With the remaining data, reverse the bytes. (using frhed, the option is in the edit menu->Reverse bytes)
4) Using a hex editor, open up the CG42.smg file created in step 1 and erase all data except the last 64 bytes of data (these 64 bytes of data should be FF's in the file). Then paste in the remaining data from step 3 to the beginning of the file and save. Your final file should be exactly 262,144 bytes large.
5) Go back to the SBFCodec window and save (this creates the sbf) the sbf file and name it whatever you want. i.e. boot.sbf
6) Using RSD Lite, flash this sbf to your phone. It may take 5-10 minutes for the flashing to complete. (after the 10 minutes, it might say "failed", just click on the show device button once that happens and you'll have succeeded)You now have a stock phone with a custom boot image. Go ahead and root your phone and stuff. Sorry for the difficult instructions, this was the only approach I could think of to edit the boot logo.
Is 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?

View 2 Replies View RelatedI 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.

I 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.
