[Galaxy Tab 3 General] r2d23cpo:
As I said I need help. I need an android user with a device capable of doing fastboot. I will try to contact a few people. But I will leave here the instruction of what I need. It can be a phone or a Tablet. But I will continue the use of the name "TABLET" as a generic term. Please use Copy and Paste to ensure that you type the correct commands.

Note to advance user. All the following instructions can be omited. I only need you to do

lsusb -d[COLOR="Blue"] 18d1:4e20[/COLOR] -v >> Test_device_info.txt

where you use instead your own Vendor/Product IDs while you are hook to the tablet. Thanks.

1) Use a Linux desktop, for example Ubuntu but any distro may work.

2) Try to disconnect as many devices as you can from all the Desktop USB ports. I know there can be exception. Maybe you need mouse!. But please as little as possible. That will help you find out what is your tablet device.

3) Open a terminal in the desktop

4)Type and execute the following to ensure adb will end and not affect us.

adb kill-server

5) Now we are going to show what devices the Desktop has before we connect our tablet. To do that we execute

lsusb

We will do it once more to sabe the result to a file.

lsusb > Test_device_info.txt

NOTE: This is a sample of what my desktop produce

6) Set the tablet or phone in droidboot, or bootloader.

7) connect the tablet to the desktop via usb cable

8) Execute

dmesg | tail -50

one more time to save to the file. It will concatenate the result in same file

dmesg | tail -50 >> Test_device_info.txt

Here is an example of what my Desktop produce

If you look at the previos info. What we are looking is the blue mark data. But to ensure anonimation I had changed the last 6 digits of the serial numbers. If you are going to post the data in the forum I suggest you do to. I do not need that,but if you send me the data captured via PM you do not need to worry, I hope you thrust in me. But I gain if I was you I do it. jijiji.

9) Now we are going todo this again to reflect the changes:

lsusb

We will do it once more to sabe the result to a file.

lsusb >> Test_device_info.txt

<== Look this time it has 2 ">>".

Now you can compare the first one and the last one to see what is your tablet info. Mine is

Bus 003 Device 007: ID[COLOR="Blue"] 18d1:4e20[/COLOR] Google Inc. Nexus S (fastboot)

As you can see the blue mark has the same info as expected. nice.

So we know our dev is 18d1:4e20

Now clearly yours is going to be different! Its your device not mine!

So in the next instruction you clearly have to exchange you own tablet data for mine in order to work. Do not forget.

yes ONLY the blue mark area

10) Now we are going to get the real data I need.

lsusb -d[COLOR="Blue"] 18d1:4e20[/COLOR] -v

We will do it once more to save the result to a file.

lsusb -d[COLOR="Blue"] 18d1:4e20[/COLOR] -v >> Test_device_info.txt

11) You can now change any serial info and compress the data to a zip or tar. So that you can upload it here into xda.

zip Test_device_info.zip Test_device_info.txt

12) one last thing If you can and you can download the attached file of the previous post and run it I will appreciate that data to.
