Hi, I have been using Rom toolbox Lite for a while now and never had a problem, untill I got the "not so great" idea to change the heapsize in build.prop - after reboot the tablet is stuck on Loading - screenshot http://imageshack.com/a/img924/2306/BJbCT1.png
I have tried to reset, reset to factory default, to push back an old build.prop by ADB from prompt, tried the same from QtADB(0.8.0(newer 32bit not availble) - seems I have full access to all folders), even tried modifying the build.prop as root and start QtADB as root then copy it back - nothing has helped.
I have a complete backup(rom dump) made with uberizer, but since I'm not using windows anymore but instead Peach OSI(heavily modified Xubuntu). I'm not really sure what to do now.
My Minami M-750 DualCore A20(allwinner) tablets info is uploaded at specdevice long time ago as I were trying to find others with the same tablet:
http://specdevice.com/showspec.php?id=e5ba-9ce5-0033-c58700000000
It doesn't have custom Rom or custom recovery, but do have an option in recovery to update from external storage(where I can access internal sdcard and external sd) - update from ADB - update from cache.
Anyone have any suggestions?
With kind regards
JBJ
EDIT: Thanks to this article below the problem is now solved.
Note: Step 1 . instead of Eclipse ADT download SDK command line tools https://dl.google.com/android/android-sdk_r24.4.1-linux.tgz
Follow this guide on how to install the SDK: https://androidonlinux.wordpress.com/2013/05/12/setting-up-adb-on-linux/
Step 3. Open a Terminal and shoot this command: —–Note: The “Android” in the command is the folder in which we extracted the SDK in.
cd ~/Android/sdk/platform-tools/
Edit build.prop using ADB
by Louis Matthijssen · July 26, 2014
There are many reasons why you may like to edit your build.prop file. I always edit it in order to lower my DPI, resulting in a bigger looking screen.
You can edit it on the device itself using a file manager or a build.prop editor but it may be more convenient to edit the file using a PC.
Please note that your device has to be rooted to edit the build.prop file.
Download and unzip the Eclipse ADT
Make sure your device has USB debugging enabled
Open a command prompt or terminal and cd to the platform-tools directory:
cd C:\adt-bundle-windows\sdk\platform-tools
Check if your device is recognized:
If it’s not you may install the Google USB driver and try again
adb devices
The device may ask you if the computer is trusted, choose yes
Restart ADB as root:
adb root
Remount /system as rw (read-write):
adb remount
Download build.prop to your pc:
adb pull /system/build.prop
Now you can edit build.prop using your favorite editor
Important: use a plain text editor! I recommend Notepad++ for Windows and Geany for Linux
Upload build.prop to your device:
adb push build.prop /system/build.prop
Fix permissions:
adb shell chmod 644 /system/build.prop
Reboot your device:
adb reboot

This is an alternative approach of rooting the Nexus without touching the bootloader.
-no downgrade neccessary
-no battery modification neccessary
-no messing around with SD card slot
-you don't even have to open your phone...
Working and confirmed for ALL ROMs, including European Vodafone EPF30/FRF91, Korean FRF91, AT&T/T-Mo Stock including FRF91

Notes:
-------
- The exploit wasn't found by me (see credits), I just implemented it as a proof of concept for the Nexus One
- Basically this method should work on all currently known ROM versions.
- I tested it on EPF30, Korean FRF91, Vodafone FRF91, US Stock FRF91.
- As usual when doing this kind of stuff: DO THIS AT YOUR OWN RISK.
- It could even work on other Android devices as long as their system partition is at
/dev/block/mtdblock3/ with yaffs2 file system and there is still some space left on the system partition (without any changes).
-------
Prerequisites:
-------
- Locked Nexus One
- Latest Android SDK incl. USB drivers
- Working ADB
- The file "freenexus.zip"

MD5: 947C20222056D7C070733E7FCF85CF15
-------
Step-by-step guide:
-------
1. install android sdk & USB drivers
2. extract the content of the zip file into the tools directory of SDK (i.e. \android-sdk-windows\tools)
-> For all Newbies: Take care that you extract the files directly to the tools folder and don't create a new subdirectory freenexus within tools!!! If you did, delete the folder and extract again!!! Check twice that there is no FOLDER freenexus in your tools directory before you continue!!!
3. open a command prompt (Windows: Start, Run, "cmd", OK; Linux: Terminal)
4. change to SDK tools directory (i.e. cd \android-sdk-windows\tools)
5. connect Nexus to USB and check if debugging mode is activated
(Settings/Application/Development/USB Debugging)
6. run "adb devices" in shell and see if there is a device listed. if not back to step 5 or reinstall USB-drivers
7a. for Windows: run "freenexus.bat" in command shell (this copies the neccessary files to /data/local/tmp)
7b. for Linux or manual installation: run the following commands
Code:
adb push freenexus /data/local/tmp/freenexus
adb push Superuser.apk /data/local/tmp/Superuser.apk
adb push su /data/local/tmp/su
adb push busybox /data/local/tmp/busybox
adb shell chmod 755 /data/local/tmp/freenexus
adb shell chmod 755 /data/local/tmp/busybox
8. run the following commands:
Code:
adb shell
(you should see a "$" prompt now)
cd /data/local/tmp
9. on your phone go to a screen where you can easily toggle wifi (widget or settings/wireless)
10. be prepared to toggle wifi immediately after you execute the next step
11. run
Code:
./freenexus
12. toggle wifi on
13. you should see something like that:
[*] Android local root exploid (C) The Android Exploid Crew
[*] Modified by ak for HTC Nexus One
[+] Using basedir=/sqlite_stmt_journals, path=/data/local/tmp/freenexus
[+] opening NETLINK_KOBJECT_UEVENT socket
[+] sending add message ...
[*] Try to invoke hotplug now, clicking at the wireless
[*] settings, plugin USB key etc.
[*] You succeeded if you find /system/bin/rootshell.
[*] GUI might hang/restart meanwhile so be patient.
13b) if you get "permission denied" error, you have most likely not followed the big red newbie hint after point 2. check this by entering "ls -l", if you see a "drwxr-xr-x" and not "-rwxr-xr-x" in front of the line where freenexus is listed you did not follow properly. Search the posts in the thread on how to correct this.
14. run
Code:
rootshell
15. if you succeeded you will be asked for a password, if not try again from step 10
16. enter the password "freenexus"
17. now you should see a "#" as a prompt -> you are root now
18. run the following commands:
Code:
./busybox cp busybox /system/bin
chmod 4755 /system/bin/busybox
busybox cp Superuser.apk /system/app
busybox cp su /system/bin
chmod 4755 /system/bin/su
rm /system/bin/rootshell
exit
exit
19. Check if you keep root rights:
Code:
adb shell
su
20. after you executed the su command the Superuser app on your device should ask you for allowance
21. you should see the "#" prompt again, if you didn't get that try su again
22. done

- General
If you are not planning to wipe your data partition (what you probably will do when installing CM6 first time) you should think about deleting all the temp files still lying in /data/local/tmp (for safety reasons and to have more space on /data):
Code:
adb shell
cd /data/local/tmp
rm busybox
rm su
rm Superuser.apk
rm freenexus
rm flash_image (will only exist if you executed the steps below in recovery section)
- Installation of Custom Recovery
If you only want root rights you are done here. If you want to install custom ROMs you have to install
a custom recovery first. Easiest way would be to download "ROM Manager" from the market. There are plenty of tutorials on how to install custom recovery/ROM at xda.
Edit: It is safer to install the recovery manually. In this case or for those of you running into problems with installing custom recovery with ROM Manager (doesn't stick) you can continue with
these steps (without remount of system partition, now tested successfully):
1) Download recovery-RA-nexus-v1.7.0.1.img to the root directory of your SD-Card
- Note: UnMount your SD-Card after copying these files, but keep your phone plugged in
- or don't mount SD-Card at all and push the file via adb to /sdcard
2) Save file "flash_image" to sdk tools directory:
3) In your terminal run
Code:
adb push flash_image /data/local/tmp/flash_image
adb shell
su
- At this point, it will hang until you choose "Allow" on your phone with the SuperUser app pop-up
- $ should now be replaced with #
5) run the following commands:
Code:
[COLOR="Red"]mount -o rw,remount /dev/block/mtdblock3 /system[/COLOR]
cd /data/local/tmp
chmod 755 flash_image
[COLOR="Red"]./flash_image recovery /sdcard/recovery-RA-nexus-v1.7.0.1.img[/COLOR]
rm /system/etc/install-recovery.sh
rm /system/recovery-from-boot.p
(and if everything worked fine:)
rm flash_image
Alternatively you can continue with step 9 and then steps 16-24 from the old rooting method tutorial
to manually install Amon_RA's recovery. You will also need the file flash_image for that (link taken from HBOOT thread).
- HBOOT
If you rooted from a Korean Rom or have installed the latest Vodafone Rom via PASSIMG you probably have
HBOOT 0.35 which makes it currently difficult to install Cyanogenmod (there is an assertion failure in the install script, at least with CM6 RC1/2. Maybe future versions of CM6 will include HBOOT 0.35 in the script) or other custom ROMs. (You are still on 0.33 if you just installed the Vodafone OTA Update)
There is a tutorial to revert HBOOT here:
http://forum.xda-developers.com/showthread.php?t=726258
Instead of using the EPF30 image you can also use any other PASSIMG file (at least if it has HBOOT 0.33,
otherwise this step wouldn't make sense...)
Note that when flashing a PASSIMG with a different HBOOT version there is a reboot after the HBOOT has been flashed, then after reboot the PASSIMG will be loaded again and the rest of the image will be flashed.
To check HBOOT and Radio version: press and hold trackball while turning on the phone. To exit select Reboot with Vol+/- and press Power button.
Caution:
After you have reverted your HBOOT, you have lost your root rights and you are back on stock recovery.
But you can (or have to) repeat the above procedure to get root rights back.
Edit:
The downgrading also downgrades your radio!!! Before installing CM6 you have to flash a Froyo Radio!
Latest one can be found here:
http://forum.xda-developers.com/showthread.php?t=723839
-------
Troubleshooting:
-------
After trying to flash a custom ROM with ROM Manager one user wasn't able to boot the phone normally and also no longer able to boot to recovery. In this rare case try to download a compatible PASSIMG file:
For example EPF30 (Europe Vodafone 2.1)
http://shipped-roms.com/shipped/Pas...ogle_WWE_1.14.1700.1_EPF30_release_signed.zip
or FRF91 (Europe Vodafone 2.2):
http://shipped-roms.com/shipped/Pas...on_VF_2.15.151.5_R_FRF91_MFG_Shipment_ROM.zip (<-this one is currently a zip in zip. You have to extract it once to get the working PASSIMG.zip)
(Appropriate US-PASSIMGs can also be found on shipped-roms.com, most likely EPE76)
Rename the file to PASSIMG.zip (case sensitive, Windows users take care that the file isn't called PASSIMG.zip.zip hidden extension)
Copy it to main folder of SD card.
Boot phone into Bootloader mode (press and hold trackball when turning on the phone, until fastboot mode starts)
Select Bootloader mode by pressing power button.
The bootloader should then start to analyse the PASSIMG.zip and ask you afterwards to install it.
You're phone (not your SD) will be completely wiped after the procedure but should work again (and can be rooted again...)
sweet!! been waiting for this! will try it tomorrow as soon as i wake up! will report back then!

Massive thanks.
Hi, I have a Italian Vodafone Nexus One with FRF91, i have followed all the steps and now in my apps there is Superuser Permission with green light. It means that i have root rights? Can I install Cyanogen Mod now? Thanks, excuse my English.
Worked perfectly on a stock AT&T N1 with FRF91. Thanks!
Excellent tutorial step by step...great work!
Can i change the password at the end?
So once gaining root, I can flash a custom recovery with rom manager without braking/unlocking the boot loader?
@fc_themaster:
if the superuser app popped up at step 19/20 then you have root rights. you can try to install ROM Manager from the market and install a custom recovery with that porgram. it also needs root rights so superuser should pop up again at that point.
@PSeeCO: you don't need to change a password. the password was only used for the temporary rootshell which you (hopefully) deletetd with the command "rm /system/bin/rootshell" in step 18. From that point on root rights are controlled via the Superuser app. If you install an already rooted custom ROM it is obsolete anyway.
@jivemaster: yes, we can! just use ROM Manager from the market to install custom recovery.

Is the any of LG_IME.apk that works on "Joestone's Gingerbread 2.3.2".
I've had extracted LG_IME form "Lavero Burgos's data2system mod of AOSP Joestone Gingerbread" ROM and have installed it to "Joestone's Gingerbread 2.3.2"
The problem is, it says force close.
Thanks
use this http://gt540.co.cc/index.php?dir=&file=LG_IME_2.3.zip
I don't know what went wrong, I've installed the zip package via recovery but it seems that the problem remains.
When I select LG IME as the input method, It does still says force close.
But thanks anyway
heres what to do with my file:
TUTORIAL #7
- Dowload LG_IME_data2system and unzip in desktop
- Open System folder and copy the 3 folders: app, lib2 and usr folders to C:\*SDK\platform-tools\
- Plug your phone to the computer
- Open a CMD terminal and type:
Code:
cd C:\*SDK\platform-tools
adb devices
adb remount
adb push app /system/app
adb push lib2 /system/lib
adb push usr /system/usr
adb kill-server
exit
- Unplug your phone
- Go to ROM Manager application and run Fix Permissions (DO NOT avoid this step, so you dont get FC's)
DONE!

Sent from my GT540 using XDA App
It works, thanks Veronica
I've followed your tutorial step by step and it works without any problem. No more FC ...
Thanks Veronica
Nearly There. . .
Followed your guide right through. Only problem I have is the T9 (predictive) won't work, the little T9 button is disabled..... no FC's though. Any thoughts ??

Hi, I just read some tips about using script for enhancing performance.
It says that the script must be places in system/etc/init.d
But in stock rom P500 (GB 2.3.3 v20G) I can't find folder init.d
The questions:
1. Is the stock rom already support init.d script execution?
2. If yes, will it works just by creating folder init.d and place script there?
3. If not, how to enable support init.d for Optimus One, stock ROM rooted?
I search this forum and find some guide about init.d support in other phone models, will it works on Optimus One too, or perhaps it needs particular way to do it?
1. No
2. If you have init.d support in rom.
3. Only way to do it is cook a custom rom through kitchen to add init.d support

3. answer is some wrong:
you doesnt need to cook a custom rom, you only need the adb (android debug bridge) to "speak" with your phone:
0.) on your phone download busybox from market
1.) install android sdk on your computer
2.) install LG usb drivers on your computer
3.) open a console (on windows use the "cmd" command)
4.) remount "root" to read/write (type following commands in the cmd)
Code:
adb shell
mount -o remount,rw /dev/block/mmcblk1 /
exit
5.) retrive the init.rc file from your device: (type the command in the cmd)
Code:
adb pull /init.rc C:\users\XXXXX\Desktop\init.rc
6.) open the init.rc file and add the busybox command to execute scripts in the /system/etc/init.d folder
after the lines that does mkdirs etc but BEFORE zygote starts (this stars the whole android)...
Code:
service userinit /system/xbin/busybox run-parts /system/etc/init.d
oneshot
7.) close and save the file, push it back to your device, than reboot:
Code:
adb push XXXX\XXXX\init.rc /init.rc
now you can use the init.d folder as in CyanogenMod / other custom roms.

That works? I mean init.rc is in ramdisk in boot partition, and gets unpacked on boot, so any changes in / are lost on reboot - at least that is what was told to me.

Option 1 - run logcat during boot (Trough ADB, type logcat in adb shell, a little simpler if using Droid Explorer)
Option 2 - Run a script that changes something that was previously different. Try installing the supercharger (with different from normal minfree values), rebooting and running the script again to make sure the minfree values are modified. If so, init.d is working and vice versa.

I go directly to this step, using root explorer on phone (not using PC+ADB)
But after reboot, init.rc i've already edited before has been restored again to original value, as said by Tasssadar.
Maybe I should do it using PC+ADB instead of direct edit on phone?

you are trying to modify a running system, sure - you have to do such things
in the boot.img file and have to re-flash it. there is no way to modify a running
system, sorry for misunderstanding.

go to your recovery, make a backup of your current system and connect the

then, use the htc kitchen to modify the created rom / or the boot.img
[TOOL]ADB + Fastboot v1.0.31 for OS X/4.3 [NOW Includes ADB & Fastboot][08-17-2013]
ADB & FASTBOOT FOR OS X
There has been some confusion since I discuss using Fastboot in this post, but the zip only contained ADB. This is completely my fault and I apologize. Either way I've updated the .zip to include ADB & Fastboot.UPDATED: 08/17/2013 - Added Fastboot to adb-1.0.31-mac.zip
I've seen several people having issues on OS X trying to use ADB since the release of Android 4.3. In my case ADB recognized my device, but each time I ran adb devices my device would be reported as offline. I downloaded the SDK from Google several times and always ended up with ADB v1.0.29 (4.2.2).
This will should solve your OS X & ADB issues if you're running Android 4.3. This ONLY includes the ADB & Fastboot executable files and is for Mac OS X ONLY. I, like many others, do not need the full SDK. If you're not an app developer, like myself, this is all you need to have ADB working on your machine.
For any new OS X users I'll add a how to just so you don't have to go search for it else where:
How to setup ADB + Fastboot on OS X
Note: This is for not for developers. This only includes ADB & Fastboot and is not the full Android SDK
Step 1: Download the ZIP containing ADB & Fastboot
Step 2: Extract the ZIP to the directory of your choice
Step 3: Optional Create an environment variable
1. Open Terminal
2. Type cd to take you to your home directory.
Code:
cd
3. Type touch .profile to create a hidden file in your home directory named .profile
Code:
touch .profile
4. Type open -e .profile to open the file you just created in TextEdit
Code:
open -e .profile
5. In the file, add the following:
Code:
export PATH=${PATH}:/PathToDirectoryWhereYouExtractedTheZIP
6. Save the file and close TextEdit, quit Terminal, and relaunch the Terminal
Step 4: In Terminal type adb devices, you should see your phone's corresponding serial number Ex: HXM1005HNF012345 device
Code:
adb devices
Note: If you choose not to create an environment variable from Step 3 it effects two things:
1. You will need to cd to the directory containing ADB each time you want to run ADB.
2. When executing ADB commands you will need to add ./ in front of ADB. Ex: ./adb devices

wad3g, thanks for helping out.. but for some reason adb version is still showing 1.0.29 for me. I extracted the zip, removed the old adb and fasboot, restarted my machine.. ran kill-server, start-server but no luck.. any ideas? not sure what to do at this point.

Hey, I was having the same issue so I took the adb and fastboot files from the SDK. You can copy them to usr/bin/ and run normally (as if the third step in the op's post had been completed), or by following the op's procedure if you're not an admin user.

For some reason, that zip still reports ADB version 1.0.29.
I found the latest version (1.0.31) from https://ftp.mozilla.org/pub/mozilla.org/labs/r2d2b2g/. It has zips for linux, mac and windows adb.

I have installed stang5litre rom some time ago via flashfire since I am on of1. Recently I wanted to make a build prop edit to add apn settings and the damn buildprop app cleared the build prop leaving it empty, which I did not realize. I then rebooted and now you can guess I cant reboot. I have looked into a flashable zip with the build prop included but it has not worked. I get package footer is wrong and signature it wrong despite me signing the flashable zip. So what can I do?
I have full ADB access and can push sideload updates my issue is the footer and signature issue. Is there a way to sideload the buildprop without getting these errors? Can I flash the org verizon buildprop from there rom to make this boot? Any ideas?
I believe I have an almost solution, see below.. The problem is my device is unauthorized when I try to do adb devices. This is while allowing the device to boot in without the screen coming on. I can not see the dialog to allow me to confirm adb access. Is there another way?
Here are the steps to restore the build.prop settings.
1. Download android developer kit.
2. Connect tablet to (in my case I used a Mac) computer via USB Cable.
3. Boot tablet to "blank" screen.
4. Open Terminal and enter the following commands.
* cd /path/to/adb
* ./adb root #runs adb as root.
* ./adb devices #lists all connected devices, confirm your device is listed. If it is not, try disconnecting and reconnecting the USB Cable.
* ./adb shell #allows you to run a remote shell interactively.
* su #enters su.
* mount -o remount rw /system #mounts /system as rw.
* cd /system #puts you in the system directory of your device.
* ls -all #lists all the files in your devices /system directory. Look for a backup file of build.prop. If one exists, look at it's contents with less.
* less build.prop.bak #shows the contents of your backup build.prop file (the name of this file may very).
5. If you have a backup of your build.prop (and its' contents are correct), you can restore it using the following commands. If you do not have a backup, you will have to edit the file using vi (see step 6).
* mv build.prop build.prop.bad #renames build.prop.
* mv build.prop.bak build.prop #restores your backup of build.prop (replace build.prop.bak with your backup file name. If there is a space in the name, type \ before the space and hit tab. It should auto complete).
* exit #until you are back to your computers adb directory.
6. If you don't have a backup of your build.prop file, you will have to edit it with vi.
* vi build.prop #edits the file using vi (you will have to google how to edit this file with vi if you don't know how; I'm not doing a tutorial on vi ).
* exit #until you are back to your computers adb directory.
7. Reboot your device! You should be back in business!!!
8. Enjoy!
I'm screwed arnt I? I tried just about everything I could find for days since I posted this. Without USB debugging enabled I can not recover my data. Not with ADB, not with Kies, not with odin, NOTHING. My phone is rooted but that does not seem to matter now. I tried every recovery app out there including dr.fone and nothing can get it back. I guess I just have to reflash to stock and loose it all uh?
