[HowTo] A2109 Fastboot

If this doesn't work, I can forget the rest.

Maybe there is something wrong with the adb and fastboot installation. Where did you download it and how did you do the installation, with a script or manually?

@anika200
No I am not new to linux, I am using it over 10 years and I am familiar with the command line and bash scripting. I have read so many instructions and got so many help, which didn't work, so I ask you very kindly to tell me the link, which I should read again carefully. I promise I do, if I know, what I should read.

In the meantime I fear my fastboot installation is not working correctly. Any ideas how to check this?

adb seems to work, because I get an info, that the device is attached, while I never got anything that looks like, that fastboot works.

I think I have to test with a simple fastboot-command first, like:

fastboot -i 0x17ef reboot

< waiting for device >

The problem is, that fastboot doesn't recognize the device, while adb does.

I've said this before, but I don't know if you've tried it: When I boot into fastboot mode by vol down + power, fastboot doesn't work. If I am in adb mode and enter 'adb reboot bootloader', when fastboot mode loads, it works (after a couple seconds to detect the device). The syntax in linux may be different, but your tablet may only work with fastboot in that fashion, as mine does.

My fastboot binary came with my adb binary via android-sdk-linux.
android-sdk_r21.0.1-linux.tgz Android SDK | Android Developers
I copied them both to /usr/bin/

I downloaded adt-bundle-linux-x86_64.zip (392.4MB)

Your adb _fastboot.zip is 167.3kb.

What I can say at first sight, that your binaries have different md5sums than mine.

Did you copy anything other than adb and fastboot from the platform-tools somewhere?

I tried all 3 fastboot with fastboot -i 0x17ef reboot and everytime I get < waiting for device >

@FloRider:
I tried 'adb reboot bootloader' very often and I do it again:

Immediately I got a blank screen on the display of the A2109A, see the "USB-connected-logo" in the middle and on the top 2 lines with

Entering Fastboot based on booting mode configuration
Starting Fastboot USB download protocol
Click to expand...

But how I go on?

Do I have to enter a command in my linux shell on the pc?

Hey, this time something worked:

# adt-bundle-linux-x86_64/sdk/platform-tools/fastboot -i 0x17ef reboot
rebooting...


finished. total time: 0.001s

I go on with testing and give a feedback, when something important happens.
 
hey you are at least making progress, as for myself I dumped the system, recovery and boot.img, modified the boot.img to always be root.
is your Linux 64bit or 32bit, i always use 32bit.

and no i did copy anything else to usr/bin/

Sorry I didn't see this, since I was trying FloRider's way and I am little step further, but now it hangs:

On the A2109A display I see:

Press <Volume Up> to select, <Volume Down> for selection move

So I rhink I should have pressed the buttons on the tablet to unlock it first, before I entered the 2nd command fastboot -i 0x17ef boot '/install_nfs/androidins/ideapad/ics/A2109_CWMrecovery-6.0.1.9c.img'
 
Ok, I see "Bootloader is unlocked now", after executing "fastboot -i 0x17ef oem unlock". I had to press first Volume down and then up.

fastboot -i 0x17ef boot '/install_nfs/androidins/ideapad/ics/A2109_CWMrecovery-6.0.1.9c.img' is fine now too:

downloading 'boot.img'...
OKAY [ 1.039s]

Yeah, it looks a lot better now. IMHO the only difference is, that I used another fastboot now.

So please be kind and help me how to go on, I am nearly done. I don't want to search in all the threads what I have to do now.

I see CWM Based Recovery v6.1.0.9. In the middle is a logo with a head.

AFAIR I need to install Superuser-3.1.3-arm-signed.zip (install zip from sdcard)

Do I have to wipe something too, if so before or after installing Superuser-3.1.3-arm-signed.zip?

There are no private data stored on the tablet.

There is:

wipe data / factory reset
wipe cache partition

There is a rumour, that wipe is necessary to get no battery drain.
 
My tablet was reset to stock once I unlocked the bootloader, just install the Superuser-3.1.3-arm-signed.zip and reboot.
 
Well, I thought it shouldn't be a problem, if I wipe with both options and after the reboot everything seems to be fine. SDMaid asked for superuser permissions, so it is rooted now. Crazy that I used a fastboot which didn't work correctly. It took me days. I will see your other hints re udev-permissions in the next time, but it looks my setup works too. To repeat it, adb and fastboot from http://dl.google.com/android/adt/adt-bundle-linux-x86_64.zip in sdk/platform-tools worked for me. I didn't try the versions of vampirefo, since it worked, but I assume, it works, since it worked at his pc. I am using Xubuntu 12.04 with kernel 3.2.0-35-generic and 64bit CPU. With XP I tried the 32bit version with a 64bit CPU. I am happy that I got it work with linux.

Thanks to all who helped me! I hope I pressed enough thank.buttons ;-)
 
Wow, good job everybody. I was beginning to wonder if we would pull it off :rolleyes:
@a2109a next challenge for you...nandroid backup.
