Yeah so i wrote this guide back in 2012, it is probably very out of date, i did update some stuff but id probably look elsewhere if these are not working. you should get newer adb files anyhow, i post modern ones on my loggingkit package here Github , there are binaries for windows, linux and mac
Hi there guys so i will be telling you how to reboot to recovery or boot loader directly from adb commands
It is pretty easy
1-Download adb and install adb drivers for your phone
2-extract the files to your c directory in a folder named adb(make one)
3-once the files are located in c:\adb go to start menu then search for cmd
4-do cd c:\adb
5-check for connectivity
adb devices
if your device is not listed, the drivers are not there
6-Finally, to reboot
For download mode (it varies from device to device)
adb reboot download (Samsungs)
or
adb reboot-bootloader ( HTC )
For Recovery Mode (it is mostly the same for most phones)
adb reboot recovery
thanks for reading.
Actually, the commands to reboot into bootloader are:
adb reboot-bootloader
or
adb reboot bootloader
Sent from my Desire S
I know thanks for replaying

I actually use the command ADB reboot-boot loader
but since reboot recovery won,t work like reboot-boot loader
i removed the slash so people can remember these commands easily
most of the roms are having this inbuilt now,
but those who dont have, its really good to use.. :good:

Hi there,
I am trying to access my device (Zync Z930 tablet) in fastboot mode. Therefore I started it by pressing Vol Up + Power until blue light appears and connect it to the PC (running Lubuntu 64bit).
Verifying connectivity with lsusb results in:
Code:
[email protected]:/home/badday/Downloads# lsusb
(...)
Bus 002 Device 011: ID [B]1b3f[/B]:8300 Generalplus Technology Inc.
So the device seems to be present. I also added /etc/udev/rules.d/51-android.rules with
Code:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1b3f", ATTRS{idProduct}=="8300", MODE="0666", OWNER="badday"
and made sure that rights are correct:
Code:
[email protected]:/home/badday/Downloads# chmod a+r /etc/udev/rules.d/51-android.rules
[email protected]:/home/badday/Downloads# service udev restart
However, fastboot does not find the device:
Code:
[email protected]:/home/badday/Downloads# ./fastboot devices
[email protected]:/home/badday/Downloads# ./fastboot -i 0x1b3f getvar VERSION
< waiting for device >
As you can see I am running it as root. When booted normally, device is recognized (of course with different vendor ID etc.) with adb and I can make it boot to recovery mode, but not to bootloader mode. Trying to do so will result in a normal reboot (from what I can see).
Anyone having some idea?
Thanks a lot,

Unable to root Zync z930
I have the same need to root the Zync z930 tab, currently there is nothing available on the internet to root this tab. If anyone of you manages to crack it please let me know, thanks!

To clarify things: I did not root my device so far.
Some additional information I found out:
Try to reboot in adb via "reboot-bootloader" results in normal startup. Furthermore, booting to fastboot mode (with vol-up-button down) with Micro-SD-Card inserted makes the device not to appear any more in lsusb.
Anyway, that made me having even less clues than more :crying:

Anyone found any method to root z930?
I'm not sure for linux but I think you will have to download drivers ,,,,,,,I had to do this for my computer (running win 7) to read my phone in fast boot
I downloaded an app called driver tools and that fixed it ....hope this helps
Ps : It maybe that your running 64 bit Os
@abdulmomin, jaydeepkhalpada: Rooting thread can be found here: http://forum.xda-developers.com/showthread.php?t=2028740
@fredworxz: Yes, I use a 64bit OS. However, for GNU/Linux drivers should not be needed as adb runs out of the box (please correct me if I am wrong).
Resolved! - See my post! http://forum.xda-developers.com/showthread.php?t=2045173
I've not only installed JB in Z930 but also successfully ADB'd it to root it
Here:
http://forum.xda-developers.com/showthread.php?t=2045173
Actually I cannot install the driver which might be some problem as I use 64bit OS and have no 32bit available. Anyhow, according to the name scheme, there should also be a 64bit version included.
Apart from that I have also problems with this Chinese software, does it need adb drivers to be installed? Actually when I boot in this mode with vol-up-button, there appears absolutely nothing in the device manager.
Would be great if you could help me out as I need this tablet for some sort of NGO project.
Greetings from Delhi,

This is not fastboot mode
as your trying to unlock fastboot ,but this is not fastboot mode
this is for flashing firmware through G+massprotection tool..
There is no fastboot mode in Z930..
but you can goto recovery menu by pressing
1st press & release Power button then press and hold vol+ button
I have Asus Fonepad 7 dual sim (Build ver. 5.5.1).
I want to root my device.
Code:
adb devices
recognizes my device properly.
Debugging mode is on.
Even device enters in fastboot mode by executing
Code:
adb reboot-bootloader
in terminal (I am using Ubuntu 14.04).
I have set up android rules in /etc/udev/rules.d/99-android.rules .
I've found out my vendor id and product id using
Code:
lsusb
(when the device is in fastboot mode). I've made corresponding entry in android rules file. But even that didn't help
I've tried
Code:
sudo fastboot devices
also. Every time I get nothing but a blank line.
Somebody please help!!

This link solved my problem . It is a correct version of fastboot which works just fine for my device.
My problem is my tablet is visible in normal mode on my pc. Bootloader 4.2.1, The Device is unlocked ok. adb devices: #serie ok, and adb reboot-bootloader function works. The tablet will reboot into fastboot mode, but I am unable to find a driver that works on my pc. I installed 1.97 pc asus sync, google sdk, minimal adb fasboot driver, all indicates error code 10
"fastboot devices" does not work. Rck is on and the icon does not flashes, the fastboot reboot feature is '' Waiting for device ". So if I disconnect and reconnect the USB cable, the tablet will restart on the OS...
Even tried with a live linux cd and still the same problem...
Note my usb cable has been replaced by a generic for my original cable had become unstable.
It can be the cause of my problem. Of course I tested with 2 cables? Factory reset and unlocke with v7 and v8 apk, and also an OEM recovery to latest firmware 10.6.1.27.5-20130902
I would like to set up a recovery to try others Roms,
Thanks for your help.

First of all, your boot loader must end with 27.5. Check it out when you are unsure before you do anything more.
Then try to flash Kang TWRP from your SD Card with Terminal Emulator using the following code:
dd if=/sdcard/ twrp_tf300t_kang_2.8.7.2.img of=/dev/block/mmcblk0p4
For more information have a look at Josh’s thread http://forum.xda-developers.com/transformer-tf300t/development/recovery-twrp-t3046479
For this soluce the tablet need to be root...
I have make this but not working, the terminal not see the file on sd card....
On terminal i see
[email protected]:/ $ su
[email protected]:/ # dd if=/sdcard/foo.img of=/dev/block/mmcblk0p4
/sdcard/foo.img cannot open for read: no such file or directory

You can't see the device while on fastboot mode of you type adb devices.
You need to make sure debugging is on in the developer preferences.
ADB appears to be working just fine for me.
When using adb make sure you have debugging enabled and grant the popup on screen
adb is not fastboot. You can use adb on twrp or booted system. Fastboot is on bootloader mode.
Also need to make sure that the proper USB drivers on the computer are installed/updated.

This is working exactly as intended, and not exclusive to Android 10, but rather has been the case as long as I can remember (Jelly Bean? KitKat? Maybe much earlier?):
adb: Only works when booted to OS or in TWRP. Debugging required to be toggle on in phone settings. Does not work in bootloader-fastboot mode.
fastboot: Only works in bootloader-fastboot mode. Debugging is not required to be toggled on.

Sounds like another adb server is still running. What does adb kill-server and then trying again do
a second adb server was running.
