We’ve already explained you about ADB and Fastboot, In case you are planning to root your android devices or send some commands to your unrooted android device then both of these are important.

#Adb quickboot how to

How to Install ADB and Fastboot on your PC (Windows, MacOS and Linux) In order to root your device, flash ROMs on your phone, or playing with the terminal commands, you don’t require the whole Android SDK.

You can get both these tools within the Android SDK, but that would be a large download and if you are only interested in these tools, then I would suggest skipping the SDK part. Well, now that you have got the basic understanding about ADB and Fastboot, it’s time to learn how to install them. Unlike ADB, Fastboot isn’t available on all Android devices and you must ensure that Fastboot is enabled on your device before installing it. However, this tool can’t flash whole ROMs, Fastboot can be very helpful for tasks that ADB can’t manage. Fastboot lets you flash/modify stuff such as custom recovering by sending commands to the bootloader. In order to modify the Android device’s firmware, Fastboot can be a very handy tool that you must install.

The main purpose of ADB is rooting or modifying an Android device, however, you can also use this tool to send commands to unrooted Android devices too. With ADB, you can send commands to your device not only when it is turned on but also during the recovery mode. Let’s learn about them one by one: What is ADB (Android Debug Bridge)?Īndroid Debug Bridge, popularly known by its acronym ADB, is an excellent tool that lets you send a wide array of terminal commands related to basic Linux shell commands as well as a few specialty developer commands to your device at any time as long as the USB debugging is active on the device. While both these tools operate differently, they are essential tools and it is always helpful to include both on your device.

The device does come with a proprietary flashing tool, but that only works under Windows XP.

Sideload mode does seem to come up in adb, yet flashing any Update.zip has so far not been succesful (maybe due to a crippled adbd?), even though I have tried various methods of crafting (signed) Update.zip files with the only purpose to reboot the device into fastboot mode. There is a button combination to get into recovery mode, but that doesn't provide me with a connection in adb.

My device does work just fine when turned on (although not rooted), but I really want to reflash boot.img to get the proper adbd back. And to reflash boot.img I need to get into fastboot mode. which, well, obviously doesn't work anymore. Also, busybox is still missing.)Īnd here's the final problem: the phone does not have a way to get into fastboot mode using hardware buttons, so I found myself having to type 'adb reboot bootloader' to get it into fastboot mode. (I suppose the permissions are messed up somewhere, chmodding went fine, but chowning did not. Applications are not getting root, either. Now, using an adb shell, I could simply get root by typing 'adb shell' followed by a simple 'su', and ta dah: root shell! Yet, somehow, the permissions on the su binary are all messed up - since when I use a terminal emulator on the device itself: I get presented with a 'Permission denied' error.

It shows the device - with an id of 0123456789ABCDEF as offline in the devices listing of adb. Now this is where the problem comes in: the hacked adbd no longer allows me to connect using adb. ( Please note: Before replacing adbd I had also installed the su binary in /system/bin and the Superuser.apk package) Replace adbd in /sbin with a version provided by a package called adbd insecure, which was supposed to automatically grant root access to adb-connections. Modify init.rc to mount /system as a rw filesystem, since (re)mounting /system is somehow not allowed by the kernel, even when root. Modify default.prop, setting ro.secure to 0, ro.debuggable to 1, and ro.adb.secure to 0. No known exploit-based root methods exist for this device (which runs on Android 4.4.2), so I found myself having to dissect boot.img using the MTK-Tools Perl-scripts.Īfter unpacking the boot image, I made some modifications in the initramfs, they are as follows: I own a relatively unknown Chinaphone, the CUBOT GT72+ (MTK6572 SoC) - on which I was attempting to gain root access.
