Linsay F-7HD rooting - Miscellaneous Android Development

eek:k so I have a Linsay F-7HD and it is giving me a fit trying to root it. This is a nice tablet with Google certifications and Google Play. A Cortex A-9 2.0 single core processor, 4G flash drive with 1.98G free, 512m, Android 4.1.1, micro sdcard to 64G. and usb host cable,ear phone plugs, usb cord and ac charger, very responsive,quick all for $99.00. I only want to root mainly to change vold.fstab, so as to switch internal and external. Also need to do a backup of Rom.
Problem is that it connects to usb, usb debugging is checked, can transfer files to or from device. I have SDK installed on C:, it works fine with all my other android devices but can not detect F-7HD in normal on mode. Recovery by pushing +volume and then power, gives me android down but can't get into any menu BUT ADB detects device and as being in recovery mode, I've tried adb push for superuser, su, and busybox. Busybox and su are there but not superuser. I tried chmod after is says all is transferred by abd push but comes back error. I also can't get into fastboot mode. I will list the abd commands below so maybe someone can give me a pointer or ANY help. I'm not good with adb but can usually Google and find commands that I need. I have the 3 files in my SDK platform tools folder and has worked before with any other device or files. I also can't get a adb shell or su to work, adb reboot only turns device off. Any help would be great. Thanks
adb push Superuser.apk /system/app
adb push busybox /system/xbin
adb push su /system/xbin
adb shell chmod 664 /system/app/Superuser.apk
adb shell chmod 664 /system/xbin/busybox
adb shell chmod 664 /system/xbin/su
adb shell reboot

Anyone have any ideas that I might could try.
Was hoping someone might have a suggestion.

+after doing that should i get official updates?

http://forum.xda-developers.com/showthread.php?t=879041
and i try this solution
ryude said:
You need to use adb to go in the file system and delete all trace of superuser and busybox. That is the only things rooting does, places those files on your phone and changes file permissions. File permissions, they won't look for, but I've had best buy scroll through the app drawer on multiple occasions looking for superuser/rom manager.
I have attached a zip containing all the files needed for adb. Since they no longer package adb with the sdk. Just open command prompt and cd to the directory containing adb. Make sure your phone has Usb Debugging enabled, then connect your phone.
You might need to download usb drivers in order for windows to recognize the device, but probably not. Once your phone is connected, do the following.
Code:
adb devices
adb shell
su
rm /system/app/Superuser.apk
rm /system/bin/su
rm /system/bin/busybox
rm /system/bin/rootshell
reboot
Click to expand...
Click to collapse
but when i write rm /system/app/Superuser.apk it say
Read-only file system
so what should i do i only get my XS unlock then install superuser using
install-superboot-windows.bat
and i never do recovery!!!!!!
so any help
i need to get my nexus like new and i should then gt updates
You can have superuser and get updates. The update will remove root though. You could always wait for the cm nightly to include 2.3.3

You have to mount the /system partition as read/write.
Easiest way is use Root Explorer.
You can also try the following from adb or terminal on the phone:
Code:
su
mount -o rw,remount /dev/block/mtdblock3 /system
thanks for your reply
i used Root Explorer to mount the /system partition as read/write.
and then
i did write this codes
adb devices
adb shell
su
rm /system/app/Superuser.apk
and every thing was ok
but i have an error on those lines
rm /system/bin/su
rm /system/bin/busybox
rm /system/bin/rootshell
and every time i get file not found
so what i should do???
hello, tominater12 and thank you for reply
cold you tell me how i can remove superuser and root using the update??????
i want to get my nexus s like new no root no superuser
so any one can help?
hi guys,
this is my first post in the forums, but after reading and watching many videos on how to remove it i have found a solution...my nexus s is now unrooted with no superuser...
make sure u have android sdk installed, and have usb debugging on.
restart phone into recovery
open cmd and type -
cd c:/AndroidSDK/tools/
adb shell mount /system
adb shell rm /system/app/Superuser.apk

USCC Mesmerize Rooting on Official 2.2 (Froyo)

Okay, this was my first time trying to root my phone and it would figure that non of the automated methods worked for me. Still, I was able to get root on my US Cellular Samsung Galaxy S Mesmerize (SCH-i500 for the kids keeping track at home) and these are the steps that I took. I hope this helps others who may be scratching their head wondering what to do when the developers haven't gotten around to (read: forsaken) us.
The nice thing about this method is that it doesn't require Windows (though you still do download SuperOneClick).
NOTE: This is only for an officially updated Mesmerize. Rooting is unnecessary for the leaked version.
APOLOGY: I can't post any links to anything outside the forum as I am a newer member, so, sorry for not being able to post URLs.
1. Download the Android SDK from the Android developer website and install/unzip it. You may need to add the path to the adb tool (found under platform-tools for me) to your PATH variable.
2. Download the SuperOneClick tool and unzip it
3a. If you are using Windows, then make sure to install the drivers for your phone. I don't have Windows, so don't ask me which file to download. Sorry.
3b. Enable USB Debugging on your phone (Settings->Applications->Development->Check "USB Debugging").
4. Connect your phone to your computer using the USB cable
5. Open a shell (or command prompt on Windows) and change directories to where you unzipped SuperOneClick
6. Run the following commands to copy files to your device
A. adb push psneuter /data/local/tmp/psneuter
B. adb push busybox /sdcard/busybox
C. adb push su-v2 /sdcard/su
NOTE: A quick note of each of these files.
A. psneuter - an exploit to gain root access temporarily on your phone
B. busybox - a compilation of common unix commands to help you along the CLI world
C. su - the super-user command used to gain elevated privileges
7. Run the following command to get a command line interface to your device
adb shell
At this point, you should see a $ prompt indicating that you are on your phone.
From here, you will change directories to where you put the exploit, change the permissions so you can run it, copy over the files that we need to sustain root access, and finally, install the Superuser.apk app so that you can manage root access from the UI.
Execute the following commands:
$ cd /data/local/tmp
$ chmod 777 psneuter
$ ./psneuter
Here, you will be disconnected from your device. This is normal. Just run "adb shell" again to get back in, though now, you will notice that the prompt has changed to a #. The following commands will reflect that.
# mount -t rfs -o remount,rw /dev/block/st19 /system
# cd /system/xbin
# cat /sdcard/busybox > busybox
# cat /sdcard/su > su
# chmod 4755 busybox
# chmod 4755 su
# exit
Now, you will be back on your computer. Type the following to install the Superuser.apk app.
adb install Superuser.apk
That should do it! You now have root access. Go ahead and try to install Titanium Backup (requires root). You can also install a terminal app or anything else.
I hope this helps. Report your successes/failures in the comments.

HTC OneX AT&T Manual root process (No Desktop)

I wanted to share my experience with following this thread
http://forum.xda-developers.com/showthread.php?t=1709296
i unfortunatly do not meet the 10 post limit
Following the process i got stuck here
Code:
Now it's time to reboot
adb reboot
After phones reboots
adb remount <-----------------HERE---------------------------
adb push su /system/xbin/su
adb shell chown 0.0 /system/xbin/su
adb shell chmod 06755 /system/xbin/su
adb shell rm /data/local.prop
adb reboot
ADB told me that i dod not have the correct permissions to push the SU file to the phone. The phone would boot, but would not load the widgets or bottom menu. Attempting to open settings would prompt Android.Core to crash.
Scary stuff
The problem was with the ADB Reboot command. It normally reboots the phone properly, but when i ran ADB Reboot, the phone cut power (off) instead of rebooting. Something did not go as intended and i needed to power on my phone, and reboot it manually without the USB cable connected (lagged too much).
After that, the ADB Remount was successful and the rest of the process ran smoothly. I am happily rooted
Thank you to all

[GUIDE] Asus fonepad 7 k012 - extSDCard write fix & hosts tweak - NO rooting

I wanna post this guide cuz i searched around and couldnt find any method for kitkat and lollipop, get full sd card write WITHOUT permanent ROOTING.
Some may say: just root, make changes with root file manager, and unroot from superSU. BUT, for this device, from what i experienced, the option for full uninstall/complete unroot, in superSU app, will just hang and do nothing .

The tweaks may work on other intel based devices, when temporary CWM recovery is triggered.
Reboot tablet in fastboot/droidboot mode - vol+ and power until asus logo apears.
Install intel android drivers - there are over 8mb limit of .7z files, so i cant add them here, just search intelandroiddrvsetup1.1.5.zip.
Connect tablet to pc with usb cable.
Unzip IntelAndroid-FBRL-05-16-2015-PTR.7z from @social-design-concepts and enter launcher.bat
type ACCEPT after reading the warning
Now:
- chose T2 if u are using Kitkat
- chose T4 if u are using Lollipop
Tablet reboots and after some screen artefacts (is normal) you are in temporary CWM recovery, which has a temporary root adb shell.
Keep tablet connected to pc.
Now download ADBfolder.7z, decompress it, and open inside a command prompt/window.
In this window insert commands, each followed by enter:
adb devices
adb shell id
adb shell mount /system
adb shell mv /system/etc/hosts /system/etc/hosts.bak
adb push hosts /system/etc/hosts
adb shell chmod 0644 /system/etc/hosts
adb shell mv /system/etc/permissions/platform.xml /system/etc/permissions/platform.xml.bak
adb push platform.xml /system/etc/permissions/platform.xml
adb shell chmod 0644 /system/etc/permissions/platform.xml
adb shell reboot
The tweaks remain even after factory reset.
For removing the tweaks, in case of installing oficial updates through OTA or manual, trigger again temporary CWM recovery, enter ADB folder, open command window and use these commands, each followed by enter:
adb devices
adb shell id
adb shell mount /system
adb shell rm /system/etc/hosts
adb shell mv /system/etc/hosts.bak /system/etc/hosts
adb shell rm /system/etc/permissions/platform.xml
adb shell mv /system/etc/permissions/platform.xml.bak /system/etc/permissions/platform.xml
adb shell reboot
It can be done, for lazy ones , with pasting these commands in two .bat files (one for install, other for remove), but I wanted ppl to see what is actually happening.
You can use another hosts file, but keep in mind the /system has limited space, so large ones may not fit.

Problem using adb with Moto C

Hi, I'm having trouble choosing the right section, anyway..
After more than a year i managed to correctly install ADB drivers, because before i installed Google driver, when i noticed i must install Motorola driver , the removing of previous one did not successful done, so the Motorola one did not installed well, by manually removing files it succeed.
But now another annoying not previewed issue, i need to exchange a file in /system/etc both in my tablet and my Motorola moto C tel. , it needs to remount system part. in r/w but to do this need to restart adb as root but with 'adb root' this is the answer:
adbd cannot run as root in production builds
my system is 7.0, what can i do?
You can install a temporary root to run shell-commmands what require root-rights like mount in ADB:
Code:
adb devices
adb push <FULL-PATH-TO-SU-BINARY-ON-PC> /data/local/tmp/
adb shell "chmod +x /data/local/tmp/su"
adb shell "/data/local/tmp/su -c 'mount -o rw,remount,rw /system'"
I have two questions, i don't find any su command available in the net.
I don't understand how it is possible to have to do all these hard maneuvers with a debug tool, i think it might be simpler.. why there's a command remount or root if it doesn't work?
