[Help needed] Acer Iconia B1-750 + ubuntu = no fastboot - General Questions and Answers

Hi, all.
I went through the forums here and googled, but I can't find one working solution.
I have the tablet in subject (Acer Iconia B1-750).
I'd like to root it using guide I found on this forum and with modification for Ubuntu from here.
I can see my device in adb no problem.
When I run lsusb, I see device
Code:
Bus 003 Device 030: ID 0502:367b Acer, Inc.
So far so good.
When I do
Code:
adb reboot-bootloader
the device restarts to something called DROIDBOOT PROVISION OS.
When I type
Code:
lsusb
I can still see the device as
Code:
Bus 003 Device 031: ID 0502:3680 Acer, Inc.
So far so good.
However, when I do
Code:
sudo fastboot devices
I see no device connected.
I tried the -i 0x0502 switch for fastboot, did not help.
I am working on Ubuntu 15.10, kernel 4.2.0-30-generic x86_64, my android-tools-adb and android-tools-fastboot show version number 4.2.2+git20130218-3ubuntu42.
I tried to modify the ~/.android/adb_usb.ini, no help.
I also ensured I have correct permissions for plugdev on the device using udev rules and I do.
Does anyone have any advice how to force fastboot binary to "see" the device?

@sancho_sk Which Ubuntu version are you using?

How to Internet Pass Through from Linux to Sensation?

Hi everyone
I have a Sensation 4g and my system runs Ubuntu 12.04.
I was wondering if there is any way to make Internet Pass Through work with Linux?
In Windows, I install the HTC Sync and it works, but what about Linux?
Thanks

It works by default
In windows it asks for htc sync coz it need drivers to recognize the device
In Linux drivers are not necessarily required
You can just connect the device and use Internet pass through
(if you got adb working on that pc already then you are good to go)
Sent from my pyramid.. Through blazing fast sonic waves
I remember this as well on Ubuntu 11.04 - I only needed to modify some lines for ADB to get it work
well add the attached 51-android.rules file to /etc/udev/rules.d/ ( remove the .txt extension to the file ..i need to add it to attach in xda )
and chmod it to 755
(i.e chmod 755 /etc/udev/rules.d/51-android.rules )
then try the pass through it might work
For me it is not working
Let me explain what I did.
First of all I connected my phone with the laptop. In the beginning the
Code:
adb devices
was giving me ??????????? but I restarted the server as root and then adb was recognizing my device properly.
Then I chose Internet Pass Through in my phone but despite the fact that Ubuntu recognize my phone as a Wired Connection 2 (Wired Network - HTC Android Phone) I don't have internet on my phone. Also when I chose the Internet Pass Through in my phone, the
Code:
adb devices
list is empty (is this normal?).
So, ganeshp I pasted the rules that you gave me in the /etc/udev/rules.d/ and I changed the permisions but no luck. It doesn't work.
Also, after enabling the Internet Pass Through after some minuter I get a failure message on my phone that says
Unable to connect to PC
Either you don't have the latest version of HTC Sync installed on your PC, or another phone is already using Internet pass-through on your PC. Please ensure......etc

davebugyi what lines you needed to modify in the adb to get it work?
No one has an answer for this? If you are using Internet pass through without problems in your linux OS share what you did to make it work.

I've got my HIS working in Ubuntu 12.04 (DHD also). No root access or adb needed. Just simple script for Network Manager. I've posted a blog entry about this, it's in Russian, but you can use Google Translate to read it. http_://blog.loquens.org/?p=489

all you have to do is to use sudo
HTML:
sudo adb devices
Do the following:
Press CTRL + ALT + T to open the Terminal.
Inside the terminal type:
Code:
lsusb
Output should look something like this
Code:
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 009 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 008 Device 003: ID 0bb4:0c86 HTC (High Tech Computer Corp.) Sensation
Bus 008 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 007 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 006 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Take note of these two values 0bb4:0c86 next to the HTC (High Tech Computer Corp.) Sensation.
Then type:
Code:
sudo nano /etc/udev/rules.d/51-android.rules
That will open a file named 51-android.rules then type:
Code:
SUBSYSTEM="usb", ATTR{idVendor}=="0bb4", ATTR{idProduct}=="0c86", MODE="0666", OWNER="username"
In the text above change 0bb4 and 0c86 with the numbers you got from the lsusb, and instead of the username type youre user name.
Press CTRL + O and hit enter, then press CTRL + X .
if your adb-server was running up until now you need to kill it and restart it as root so type the following:
Code:
adb kill-server
sudo adb start-server
Then to check if everything worked out type
Code:
sudo adb devices
If all went well there should be an output similar this and you are good to go:
Code:
$ sudo adb devices
List of devices attached
BLABLABLA device
Edit: I assumed by the way that you have turned USB Debugging on :> that covers adb part, for the Internet pass trough you dont need drivers for linux just select the mode when you connect your device and you should be good to go.

Fastboot does not find device [Zync Z930 tablet]

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:
This is cheap chinese phone with an equally defective android implementation. The battery just lasts about an hour, I am sick of it.

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

[Q] A700, under Linux no access with adb...

Hi,
In fastboot mode my linux distro (Debian testing) can see and reboot the device:
Output of lsusb:
Bus 003 Device 011: ID 0502:33a5 Acer, Inc.
but with ./adb devices, I cannot see anything:
No trace in lsusb, debug usb is on, udev rules are ok, adb_usb.ini is ok and with ADB_TRACE="all", everything is ok except that there is no device in adb...
Any clue?
Thanks.
Ps: I did google around...

[Q]Why does fastboot fail to detect my device?

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!!

[Q] Fastboot not working for Intel devices on linux

There seem to be a problem with fastboot for intel devices on linux. I am running Ubuntu 14.04 and I have an Asus Zenfone 5 a501cg. Adb works fine. I have updated the udev rules. When I try fastboot, the device is not even detected. I see the device connected in lsusb. But fastboot devices shows me nothing. And I have inserted the new device ID when the fastboot mode into the udev rules.
I mean when I installed Intel android drivers in windows, everything works fine. I have used fastboot in windows and it works. But when I use it in ubuntu, it does not work. I have tried searching around. And it seems that intel devices have a problem with fastboot in linux. There are similar questions in forums asked for lenovo phone with intel chip in the intel developer zone and the intel guys are telling why don't you update your udev rules blah blah blah..
Do you guys have same problem??????
Do you guys have a solution???????
