idea for dualbooting android builds... somewhat

alrighty, basically im lazy and want someone else to do this for me.
heres my idea:
you install rc33 or whatever you want, make a nandroid backup of it, rename the folder to OS1. this folder contains your boot.img data.img and so on
then install or place a nandroid backup of another build into a folder called OS2..
then you would be able to boot into the modified recovery mode, which would have the selection to run a script, which then asks which OS to flash, 1 or 2, you press 1 or 2 wait for it to flash and reboot, a little hacky way to get a dual boot...
now who wants to repack a recovery image for me?

good idea would be worth a try , too bad im not up to par for the job , but id like to see it done

i'll give this a shot tomorrow and see what happens, not really feeling like doing it now. and i'm not gonna do it via rebuilding the recovery.img, just gonna make a script that does it for me from the recovery terminal. i'm quite lazy as well and i already have a script that runs the fastboot commands from my computer script to flash from one build to another, in theory it shouldn't be too hard to get the script terminal reaady and do that.

Pretty simple. I have them stored to my desktop. I save my nandroid backups to the appropriate file and just double click. No problem. I just wish there was a script that I can use to reboot into HARDSPL mode (someone tell me if there is).

This is the worst idea i've heard so far...
FLASH has a limited life-time, and rewriting the whole system at every boot is a BAD idea.
If you want to dual-boot, you should look into making your own init-system, adding the ability to load another system (From SD).
Binary100100:
"adb reboot bootloader"

there might be a simpler way: change the kernel command so it mounts somewhere in sdcard as root. not sure how to do this without a computer though.

Hey binary, with your phone plugged into your comp pull up you cmd and type adb shell reboot bootloader, the phone will boot right into fastboot mode making it easy to continue the script

just to clarify...i meant a script that is store locally on the device in the recovery image... so then you dont need a computer at all... you can already do this, you just have to type in the commands from the recovery console...i just wanted an easier way to do it

To flash back and forth from windows? You've been running Windows Mobile on the Dream? I must be missing something.

not flash at every boot...just so you can text out a build and if you dont like it go back to a stable one on the go....
again, im taking the lazy way out

Disregard! - My mind ran ahead of what this post was about and I posted something regarding a slightly different idea!
I don't know about re-installing Nandroid backups...
But, if one wanted to be able to run two different installs...
Seems to me an easier way about doing this would be to have a modified SPL. It could have the option of selecting an update file...
For example, one could put two files on their sd card - update1.zip and update2.zip. The SPL could have one of the following options:
1) reboot into recovery mode - select "alt-s" - then you would have an option to select 1 or 2.
2) have an additional "Alt- " option.
"Alt-s" - runs update1.zip
"Alt-?" - runs update2.zip. (dev could pick the additional letter)
I think this would be great! No reteaching of anyone how to use the process. And, one could leave the primary use-able update.zip as "update1.zip" and use the other as the version being tried out. It wouldn't be a Nandroid back up... But, with the new "nowipe" builds it should work well.
My $.02 worth.

To be fair, that limited life-time is something like 1,000,000 writes, which would take about... oh... a year straight of constantly rebooting your phone(assuming it takes 30 seconds per reboot)
EDIT: and that assumes re-writing the whole system every time you boot, which I don't think he means since he's saying its in the recovery image.

hmmm....
I know that from the alt+x console you can do this....
mount sdcard
echo "boot-recovery
--update_package=SDCARD:build1/update.zip" > /cache/recovery/command
reboot recovery
so if you wanted 2 builds available (I would think you would need a wipe for 2 completely different builds) but....
make 2 folders in on your sdcard
build1
build2
place a copy of the update.zip from each build you want to boot in the folder
make a script like this
Code:
echo "boot-recovery
--update_package=SDCARD:"$"/update.zip" > /cache/recovery/command
reboot recovery
save the script to the sdcard directory
then when you start your phone you could
1. type "mount sdcard" (no quotes)
2. type "sh sdcard/script.sh build1" (for build 1 located in /sdcard/build1/update.zip)
3. type "sh sdcard/script.sh build2" (for build 2 located in /sdcard/build2/update.zip)
problem would be when wipes are needed. But if you have 2 solid builds and don't need to wipe when swapping it should work.
Just need a way to make a script or bootloader that could run either one of these.
Cannot see another way around it since the OS is loaded into phone ROM/RAM
of course if your build supports the reboot command from the OS then you could just make a script to run when you want to reload the other build. Then you could skip the recovery console.

@beagz - Ha, forgot about that script. Yes, to switch between say, the DudesG build and Haykuro's H build one could write a script like that in Gscript and change back and forth when a new build comes out.
Like now... One could run Dudes G build and try out Haykuro's new ADP1.5 build.
But, I do believe your right about going back to a JF33 build - would need to wipe...

Nah.. I was referring to using a bat file on my Windows computer to switch between 1.1 to 1.5 back to 1.1 by just executing the bat.
Now that i know that "adb reboot bootloader" will work it can be completely automated!
... but will it default to fastboot? Hmmm...

Thanks! But is this going to put the phone in FASTBOOT mode? I'm trying to make this completely automatic if it's possible. Simply keep your latest and greatest backup .img's in a certain directory on your computer and EXECUTE!
Take a shower or whatever... come back and VOILA! Your previous backup.
The method that I've come up with thus far is pretty simple... but you just can't execute and walk away. You still need to enable FASTBOOT at the least on the bootloader. Although I haven't tried messing with it lately. I have my phone just like I want it.
Now that the Official ADP1.5 is out let's get to work on Mulitouch, themes, etc!

Wow this seems crazy but it just might work. Lol.

bat file to automatically restore backups using Windows!
So all you need to do is...
Open notepad, copy and paste the quoted text below, edit the top line of this bat file to the directory of your backups (I used "c:\android" for an example), save as .bat and double click. Wait and your done. Just watch it happen automatically.
Also if you decide to change that directory on the top line also use the directory on the 14th line. Your done. Easy restore to a backup.
HINT! Make a couple of these with a variety of directories on the top to change what backup your want to flash back to.
Example: c:\android\rc33; c:\android\501h; c:\android\adp15; etc
cd C:\android

This one is even more noob friendly... but it's not as fast because it requires you to enter the location of your backups.
I hope it helps someone out there. It helps me.

[email protected]:
The average lifetime of flash is 100.000 writes, and flash isn't delivered 100% intact, they're usually delivered with faulty blocks (Depending on where you get it, blah blah blah).
That should change your numbers a bit (A month i believe?)
And, sure, he is using the update-zip, so it's not written to the same pages every time.
But still, it's a bad idea (Other than wearing stuff down, it will also be very slow ).
To dual-boot, modifying the init-system so it could choose from different android-runtimes would be way faster/cooler...

If possible, this would be pretty damn useful. Using a stable build while being able to tinker with experimental builds. Would definitly cut down on the constant flashing back and forth.

Need an easy programing hand... Create bat file =)...

It's been a long time since the last time I made a bat file and it seems I can't remember how to exactly make one xD... I'm kind of tired of having to put the commands to change the radio, spl and recovery every time, so I've decided to make a simple bat file to be able to choose what files to install if files 1 or 2 (1 being old radio, spl, recovery, and 2 being the new)...
Here is what I got so far xD...
Code:
@echo off
cls
:start
echo.
echo 1. Press 1 to install old files
echo 2. Press 2 to install new files
set choice=
set /p choice=Press 1 or 2 to continue
<--- This section is for option 1 --->(this lines are just to show what option is each)
C:\Android\fastboot flash radio Radio1.img
C:\Android\fastboot flash hboot hboot1.img
C:\Android\fastboot flash recovery recovery1.img
C:\Android\fastboot erase system -w
C:\Android\fastboot reboot-bootloader
<--- End sextion 1 --->
<--- This section is for option 2 --->
C:\Android\fastboot flash radio Radio2.img
C:\Android\fastboot flash hboot hboot2.img
C:\Android\fastboot flash recovery recovery2.img
C:\Android\fastboot erase system -w
C:\Android\fastboot reboot-bootloader
<--- End section 2 --->
fin:
I hope anybody can give me a hand into this =P... I've forgot almost everything in creating this kind of files xD... I know I can make 2 different batch files for the diferents files, but is more commfortable to have everything in just 1 file...
Thanks in advance

YEah..... Not sure how much you want to mess with automated Radio/spl installing. those are the 2 most dangerous parts and what happens if you get an error mid way through?
Be careful

That's why I'm including a "press a key to continue" after each part ...
The only problem so far, wast test the script and forgot to make a nandroid backup xD...

I think this is what you want:
Code:
@echo off
:start
cls
echo 1. Press 1 to install old files
echo 2. Press 2 to install new files
set /p choice=Press 1 or 2 to continue:
if %choice%==1 goto choice1
if %choice%==2 goto choice2
:choice1
echo Choice1 command should go here
set /p anykey=Command complete, press any key to continue...
exit
:choice2
echo Choice2 command should go here
set /p anykey=Command complete, press any key to continue...
exit
Reference:http://en.wikipedia.org/wiki/Batch_file

Thanks, I've already got a functional batch file...
Now I'm gonna port it to C or something to get a program that works for everybody, that way it would be easier to change the radios and stuff...

[Q] [Solved] batch file question(s) for auto adb

okay so im creating a batch file for a little automation just mainly for rebooting the device into bootloader/recovery.. i have gotten most of the way through but at the end i would like for the batch file to stop and allow for further manual input (like i have it set to reboot the device into bootloader and then i would like the window to stop and allow me to MANUALLY input the next command such as flash/reboot/whatever) however i cant seem to find any way of doing that
HERE IS WHAT I HAVE CURRENTLY
it all works perfectly just for the issue i cant seem to work out

I am not sur to understand exactly what you want to do, but you can do what you want in you batch file, it is what you did with for exemple :
- "Reboot Device into Bootloader [FASTBOOT]"
- "Reboot Device into Recovery [CLOCKWORK MOD]"
You have just check the choice with a number and after execute your "code".
So, if you know the "adb script" in addiction of the command you want, go to "code" it.
I remake your script and i especially add an exemple.
- "Execution" and "Code" are more clear.
- It is better for checking error.
- Now, this script is able to check if you are in "64bit" or "32bit", and check if the "ADB Tool" is in his correct way.
- Now, this script is able to check if you have connect or not your device.
- You can see the BootAnimation without "Power OFF" and then "Power ON" your phone.
- It is more beautiful, even if it is not very important.
The new "code", with your previous "started code" :
Code:
Even this topic is solved, i remove my code.

cheers for the reply.. but that was not really what i was after... i did some more googling and what i found was (in the last 2 minutes) that i needed a CMD /K at the end of the file.. which leaves the command window open and i can now enter in fastboot commands manually (for flashing etc)... i have attached the file as a.txt for anyone to use themselves if they were so inclined..
1. just make sure the directory of your adb/fastboot.exe is in the same directory as mine (CD c:\program files (x86)\android\android-sdk\tools) and change the 2 lines if necessary with note pad by opening the .txt normally as yours might be in program files or in platform-tools not tools, etc
2. change the extension to .bat and not .txt
3. chuck it in your task bar/start bar etc for quicker acess
and should be good to go =]
edit: i see the checking that the other fellow put it can do the checking for you.. but for me i knew the directory, etc

So, i did not exaclty understand your aim, but you have found it, so it is perfect.
I remake my previous script to do exactly what you want, and i always check every thing during the execution, to know the mistake when we have a problem. Because my version is for everybody, even if i think it is just for us. (Views: 45)
So if you want it, or someone else, just ask me.

no worries mate it was my first time writing an entire script so im pretty stoked with the outcome i tried to keep it looking as real as scripts i have seen as possible.. =]

I will continue to develop this idea : "A easy way to use ADB Menu".
When i will have finish, if you want i will post a link here to it.

sure mate.. ill edit the op if you like and can sort something out?
i think the simpler nature allows for much to be automated for mundane tasks... as long as you keep the fastboot commands manual so noobs dont do anything incorrect

In addition of this, i will post the final "A easy way to use ADB Menu" on a new topic on other section.

[TUTORIAL] Make your own zipping and extracting tool.

Disclaimer
Code:
I have made this tutorial just to help people and share what I learnt. This tutorial in no way can cause any damage. But in case you yourself have done something wrong, I will be in noway responsible for it.
Pre-requisite knowledge:
1. A little knowledge about batch commands cause I'm not going to explain the basic commands like ECHO, PAUSE, CLS or similar commands here.
2. How to use a PC and keyboard.
Things Needed:
1. Notepad++ (Google it!)
2. A 7z file.(Most important)- Get it from here.
3. A windows machine.
4. An unbricked brain.
5. Kindness to press THANKS.
How to do it?
1. Open notepad and enter the following command to start your coding:
Code:
@echo off
color 1f
title Zipper Unzipper by alokbina
You can replace the title with whatever you desire. The title comes at the title bar of your CMD window.
2. Now making your menu for creating the 2 desired options. For that leave a line after writing the above code and write the following code:
Code:
echo.
echo Please select one of the following options you want to do :
echo.
echo 1.Unzip/Extract zip file.
echo 2.Compress/Zip/Archieve files and folders.
echo x.Exit
echo.
set /p se=Select your decision
if %se%==1 (goto unzip)
if %se%==2 (goto zip)
if %se%==x (goto exit)
Here you can change the word "se" with your desired letters but be sure to also change all the "se" with the same letters.
2. Now make 3 folders in the directory where you are making the tool named as COMPRESS, EXTRACT and zip. In the zip directory place the 7za file that you downloaded. And in both the other diectories, i.e., COMPRESS and EXTRACT make a folder named INPUT in each folder.
In the /COMPRESS/INPUT folders you will place the files you want to make a zip and in the /EXTRACT/INPUT folder, you will place the zip that you want to extract.
3. After that we will build our first menu, that is, the unzipping menu. Use the following code for that:
Code:
:unzip
cls
echo.
echo Please place the zip file, i.e. the zip you want to extract in /EXTRACT/INPUT directory.
echo.
pause
echo Extracting...
echo.
mkdir %cd%\EXTRACT\OUT
if exist "%cd%\EXTRACT\INPUT\*.zip" (call %cd%\zip\7za.exe x "%cd%\EXTRACT\INPUT\*" -o"%cd%\EXTRACT\OUT")
echo All done! Congrats. You can find the extracted files in /EXTRACT/OUT directory.
echo.
pause
goto exit
Here the mkdir command will make a directory in the /EXTRACT folder named as OUT where you can see the the extracted files.
4. Now time to build the zipping menu. Use the following code for that:
Code:
:zip
cls
echo.
echo Please place the files and folder you want to compress in /COMPRESS/INPUT directory.
echo.
pause
echo COMPRESSING...
echo.
mkdir %cd%\COMPRESS\OUT
start %cd%\zip\7za a -mx9 -tzip "%cd%\COMPRESS\OUT\compressed.zip" "%cd%\COMPRESS\INPUT\*"
echo All done! Congrats. You can find the compressed zip in /COMPRESS/OUT directory.
echo.
pause
goto exit
Here mkdir will make a directory in the /COMPRESS folder named as OUT where you can see the the compressed files named as compress.zip. Here the start command will order the 7za file to compress the files. Thus another window will open for compression.
5. Now finally making the exit command. Use the following code for it:
Code:
:exit
exit
So finally you will have 3 folders-COMPRESS, EXTRACT and zip. In zip folder you will have one file 7za and in the other 2 folders you will have a folder named INPUT in each. Your final coding will be something like this:
Code:
@echo off
color 1f
title Zipper Unzipper by alokbina
echo.
echo Please select one of the following options you want to do :
echo.
echo 1.Unzip/Extract zip file.
echo 2.Compress/Zip/Archieve files and folders.
echo x.Exit
echo.
set /p se=Select your decision
if %se%==1 (goto unzip)
if %se%==2 (goto zip)
if %se%==x (goto exit)
:unzip
cls
echo.
echo Please place the zip file, i.e. the zip you want to extract in /EXTRACT/INPUT directory.
echo.
pause
echo Extracting...
echo.
mkdir %cd%\EXTRACT\OUT
if exist "%cd%\EXTRACT\INPUT\*.zip" (call %cd%\zip\7za.exe x "%cd%\EXTRACT\INPUT\*" -o"%cd%\EXTRACT\OUT")
echo All done! Congrats. You can find the extracted files in /EXTRACT/OUT directory.
echo.
pause
goto exit
:exit
exit
Now you can successfully share your tool.
Note-You can practically change all the text written after : (the colon) but make sure to edit the goto command in the same way.

[GUIDE][TOOL]Nexus 9 Splash Screen Tool v1.6

This is a Windows batch script that converts png, jpg, bmp, or tif images into a raw rgb565 image, then flashes it to your Nexus 9 to replace the stock Google Splash Screen. With version 1.6 this script will work with any resolution image; using some built in scaling, cropping, and rotating. I have successfully tested this on my Wifi 32 GB Nexus 9 using Windows 7 Home Premium, but the batch file should work for all versions of Windows, even XP.
If you do not have windows and want instructions on how to do this manually, click the button below.
Make sure you have fastboot.exe, adb.exe, and your raw rgb565 image that you want to use in the same folder. Issue this command:
Code:
adb reboot bootloader
Please verify that you are in "FASTBOOT USB" mode and not "HBOOT"
In the next command replace imagefile.raw with the name of the raw file you want to use.
Please verify that your raw image is 6291456 bytes in size. This is checked for in my script, but you need to check it!
Why?? Because total pixels (1536*2048=3145728) * Bpp (2) = 6291456​
Code:
fastboot flash splash1 [i]imagefile.raw[/i]
fastboot reboot
That's it!​
You need to have an unlocked bootloader.
You have to have your necessary ADB drivers installed and functioning correctly.
You have to unzip the n9splash1.6.zip file into a new directory.
You can use pngs, bmps, jpgs, tifs, ....Pretty much any common format
To use, just drag and drop your image onto the n9splash.bat file
Make sure your Nexus is turned on and plugged into your computer
Follow the prompts from there
This download contains the programs ffmpeg.exe, adb.exe, & fastboot.exe.
It also contains my batch script, which can be viewed in the following post.
Notes:
To flash back to stock with v1.6, just open the "sys" folder. Inside is a "stock.bat" file. Run it, and of course make sure your device is plugged in to your computer and that your device is on.
With v1.6 you can also flash raw rgb565 files. The catch is that they have to already be the correct size, in bytes. There is no image information (like width, height, headers,...) in raw files as they are nothing but pixel data. So I can't take a raw file of yours and turn it into a ....x.... 2bpp image without knowing what the original width and pixel format is.
I check the size of the file several times before it is ever flashed, so you don't have to worry about a bad conversion being flashed.
Believe it or not the file size is the most important thing, it does not matter one bit what the file contains. But if it is 6291456 bytes, guess what? You are gonna have a new splash screen. It might look like a snow storm on your grandmothers TV, but there is no difference in rgb565 data and an executable files data, there is still 8 bits in a byte and that byte still has the same potential values.:cyclops:
If you don't care to see your images open up before rotating, or before reconverting and showing them to you before flashing, you can edit the n9splash.bat file and change:
Code:
set "showbeforeflashing=yesure"
set "showbeforerotating="
If you want it to show you the image, put anything to the right of the "=" sign. If you don't want it to open the image, have nothing after the equal sign (except for the closing quote). And of course save the file after you change it.
Version 1.6 probably will not work on Windows XP. You may get it to work by editing this line at the top of the batch file:
Code:
set "usedefaultviewer="
to
Code:
set "usedefaultviewer=yes"

How to solve the signature mismatched problem when flash a modified bootloader.
I have read your post about Google Splash on Nexus 7. I have found out the Google logo. with your help. However, when I flash the new bootloader into my N7, I got signature mismatched problem. Do you have any experience about this situation?

Hi,
Is not working here, i drop my png in n9splash.bat and the .bat closes itself and nothing else in the files.

Quick note to anyone reading this thread:
This user is talking about the Nexus 7 2013, it has a totally different bootloader setup than the Nexus 9. The thread that the user is referring to is this one: http://forum.xda-developers.com/showthread.php?t=2764354​Yeah, after I figured out how the image was encoded on the Nexus 7, the first thing I did was to try to change the image. I didn't try much and here is why. The signature mismatch is a safety in fastboot. There are ways around that (like "DD"), but then you would still have to conquer the even bigger wall of Qualcomms "Secure Boot". If you are really wanting to try and change it, you would have to find some way to disable secure boot. In your bootloader screen, there is some green text that says "Secure Boot: Enabled" (or something like that), you would need it to say "Secure Boot: Disabled"
I'm not saying it isn't possible, but no one has ever shared how to do that. There is a series of file checks that happen, where one file in the bootloader checks the next (or previous) and so on. To learn more about it, please visit E:V:A's thread about the bootloader. It is real thorough and involves a lot of leaked information, because after all, it is proprietary stuff you are messing with. While you are there give him a thanks if you don't mind.:good:

What version of Windows are you trying it on? Do you for some reason have Command Extensions disabled? Can you upload the file on here, or somewhere else and send me a PM with the link?

I've sucessfully flashed your image using my Windows 7 computer, and I just did it on a Windows 8 computer. I'm updating to Windows 8.1 right now, to see if that makes a difference. One possibility is that for some reason "command extensions" has been disabled on your computer. You can test it by editing the n9splash.bat file with any text editor, and insert this at the very top line above everything else.
Code:
setlocal enableextensions
(it should be on it's own line, above everything else)
Save the batch file, and try it again.

@Max128
It worked fine on Windows 8.1 too. Are you trying to do this with v1.6 or v1? Because you can't use images that are out of aspect or out of resolution on v1. You can use any image with v1.6.
EDIT:
I've attached two files.
meGTv5n.cab is the raw image that you need to flash if you want to do this manually. It is not a cabinet file like the extension suggests, it is the raw rgb565 file of your htc logo. "fastboot flash splash1 meGTv5n.cab"
meGTv5n_test.png This is how the splash would look. This is also a file that you could use on version 1.0, if that is indeed what you have.

Hi,
I add your line like you said: setlocal enableextensions , and is still not working , the command prompt closes after i drop the image and nothing. Yes i use your last version 1.6.
Now.. i have flash your meGTv5n.cab and is working great on my tablet. Thanks you!

Have you find why this does not work for me? the conversion.

No. It is really hard (but not impossible) for me to fix a problem when I can't replicate the symptoms. I have drawn it up as a fluke, since It worked perfectly for me on the same OS, but I didn't know you were still interested. But, if you want to try to make it work, I do have some things to try.
Copy and paste this code below. Save it as anything.bat. DRAG a file onto it, and report if it runs, AND when it stops running, if it does.
Code:
@echo off
echo.Echo off....Press any key.
pause>nul
color 0b
echo.Color set...Press any key.
pause>nul
setlocal enabledelayedexpansion
echo.Delayed expansion enabled.....Press any key.
pause>nul
set "vers=2000"
echo.Variable set...Press any key.
pause>nul
title Nexus 9 Splash Tool v!vers!
echo.Title set....Press any key.
pause>nul
mode con cols=78 lines=45
echo.New windowsize...Press any key.
pause>nul
echo.The file you dropped is %~1
echo.Press any key.
pause>nul
echo.Did you make it this far....
pause>nul
In the meantime, I have no problem converting images for you, if you pm me the image or link.

I created a .bat with your code and I drag an image into it.
I got this:
Echo off....Press any key.
Color set...Press any key.
Delayed expansion enabled.....Press any key.
Variable set...Press any key.
Title set....Press any key.
'mode' n'est pas reconnu en tant que commande interne
ou externe, un programme exécutable ou un fichier de commandes.
New windowsize...Press any key.
The file you dropped is
Press any key.
Did you make it this far....
Also when i drag my picture in the n9splash.bat, the window closes right away but I managed to see: findstr is not recognized as an internal control ..
This can probably help.

@Max128
Yeah, that can definitely help.
Open a cmd "command" window and type:
Code:
findstr /?
does it say the same thing?

Yes the same thing.

That's the problem. In the windows command shell you have internal commands; that are built into the command shell, and you have external commands, that are actual programs (most of which are shipped with Windows, but you obviously can make your own). I always thought findstr was a built in Windows internal command, but thanks to the pros at www.dostips.com, I have found out that is is an external command. It is located at C:\Windows\system32\findstr.exe (your drive letter may vary).
Here is how you change your path in Windows. You don't want to delete everything that is already there, you just want to add "c:\windows\system32" to the path. Make sure there is a semicolon separating it and all the other variables too.
