AccessUSB uses RSA-2048 encryption. To get access I replace its key in TV firmware, but still looking for original key. If anyone have original AccessUSB, I can copy that RSA key and make a clone.
Original AccessUSB can have time and/or usage count limitations, clone will be without any limitations. So if you help me with this key I will provide firmware and instructions how to make your own AccessUSB. Contact: PM or lgexplorer [at] tutanota.com.
Also looking any other info about original AccessUSB.

AccessUSB devices are signed individually by LG, and I was told that they are pricy to get even for repair shops.
I was making my own one with a BeagleBone Black and CDC-ACM aswell, but deemed it useless due to the existence of better ways to get root and the signature check (serial.pem) on the device

Did you got original AccessUSB or valid RSA key? How repair shops can obtain it?
Root is only one feature, that can be obtained via AccessUSB, also it is official root access method, that will not be "fixed" in updates.

USB access is sweet but i noticed that LG store has more than one IPTV apps how is that so. But no KODI app or is there a way to convert APK to IPK and install on to WebOS.

Key mapping tool - betatester needed

For all people that haven't seen i release a version here
OLD
Hi to all, as i announce i prepare a sinple tool to change key mapping, but before release i need someone to test it (i don't have much time).
I don't accept any other user to the group because only two submit some comments.
This is a screenshot:

as bsg is totally written in python and it can run on win/lin/mac
This tool doesn't change the kernel. Produce a simple androidupdate so you can revert changes without flashing.

Very cool...
Yeah... If you want I'm your man
Send me a PM.
Cheers.

pola100 with incubus Froyo rls11.
I can test if you want (Polaris100)
Add me
Thanks
Subscribe to this group and i post you the program...
I found this program really useful! Now I can configure each key to my likings. By the way, is there a manner of configuring the full press of the Camera button?
Did you flash latest kernel?
Feedback...
Hi,
I don't know how to post attachment in your social post (!), sorry...
What works :
- power for wake and wake-up
- call
- end-call, when your're in communication
- GPS : back
- explorer : menu
- long press power or end-call : options of phone
What doesn't works (with the configuration of tool) :
- long press call : search !
- when I see home, press end-call : wake !
- short press camera : home !
- long press camera : recent applications
And I think (if it's possible) you can make options for :
- long press end-call
- long press call
And I test the bootgenerator but impossible to generate the .sh file !!
Thank you, I hope that's help you for better tool.
Cheers.
i have update bsg try now...
Great!
Is it to say, we can use an app to config the key mapping?
Do you mean an android app?
that's a great idea liquid, i suscribe
thank you
Phone function and voicemail keypad mapping
Can this tool be used to remap the telephone keypad when the user accesses their voicemail so that the number keys show voicemail function terms like 'msg del', 'msg save', 'hear msg', 'msg replay', etc.
I don't know about other carriers but AT&T has the stupid voice prompting that tells the user what number to push to perform a function such as 'To delete this message press 7'. Wouldn't it be so much better to show under the 7 on the key instead of "PQRS' have it say 'msg del'.
I can't believe there's no android app already available that accomplishes this capability.
No, you need a program to do this
Hey this tool looks nice. It will be very usefull and from time to time the key mapping changes in some roms.
What is with the Voicerecord button? I got a pola200 and its on the top left above the volume button. Is this on a pola100 too? Or is it what you mean with camera second?
Another question: will it be possible to map a short and long press feature to each button?
Atm i use incubus froyo and on explorer button is settings on short press and keyboard on long press for example.. would be usefull for every button ;D
So good developing hope it will be finished soon and that you share this promising tool

Key mapping tool - released

Hi to all, i decide to release the keymapping tool for polaris (updated with vogue)

a little side-note:
use python 2.7, not the current/latest release 3.1, otherwise the script won't work (at least it did not on my pc )
Thanks for the answers.
Can confirm: working on pyton version 2.7, not working with version 3.1.2.
I am not sure what "Wake with" function is supposed to do. I took it like, when the screen in black and phone is locked on pressing a checked button will light the screen up. Is this how is supposed to work? For me it doesn't.
This is great..thanks!
Is there anything like this for the Kaiser?
if you prepare a photo like vogue or polarisfor kaiser i can add it.
gives an error when i try to save for the vogue:
Code:
File "C:\Users\Jace\Documents\androidtools\tools\keymapping.py", line 416, in
createscript
self.writevogue()
File "C:\Users\Jace\Documents\androidtools\tools\keymapping.py", line 334, in

+self.wakestatus(self.wakecamerafirst.get())+'\n')
AttributeError: Frame instance has no attribute 'camerafirstop'
and something similar with the polaris
Hi mate,
when using python 2.7, this error message shows up when saving androidupdate.tar:
Code:
Exception in Tkinter callback

akestatus(self.wakegps.get())+'\n')
AttributeError: Frame instance has no attribute 'backop'
Is version 2.6 mandatory please?
I'm sorry, i forget to commit latest version. Try now.
how do I use this file?
just overwrite the file on my phone? how to do that? Thanks!
Apply android update using boot menu or bootscript generator
Works great now.
Thank you.
Hi how should I map the camera key in the Kaiser...there are also a couple of other keys (the two close to the focus wheel in the top left side of the phone) not listen in the Kaiser part. One is the other "ok" and the other is the "search" key.. wich in winMo I don't know what it does.. I think is intended to chat or something (there is a comics ballon on it)...
I'm looking around for a method for find the keycode on android but I can't find any working solution..maybe you should quickly point me in the right direction.
Look the dmesg after pressing the key is not giving any answer.. -.-
By the way it's a really great tool!
thanks
Hello! Found this thread and utility program very actual for me
I'm using HTC Diamond 2 with Android and want to remap "Power" and "End call" buttons. It is very natural to press Enc call after the conversation, but it is completely inconvenient to use it as power off... On the other hand, the top hardware button works as "Home" in Androd while it is designed to be "Power" as like on the original HTC Diamond and iPhone.
Is there any way to remap these keys functionalty in Android in a free way, say, to leave "End call" on the "End call" button, but move power off to top hardware "Power" button?
I'm new to Android, but a littlie familiar with linux, so I could edit config files if it is necessary. Thanks in advance!

​
macroMote, the only remote control application you need for your computer. Functionality? Using a command based system macroMote allows you to easily create the functionality you need to take control of your computer remotely. Design? With its tabbed layout organizing your macros has never been easier, this means your macros can be categorised how you want them to be. Simplicity? Everything about macroMote screams simplicity, after all that’s what a remote is for right? Macros can still be created (and removed) while clients (yes, more than one device can be connected at the same time!) are connected; the changes will be synced to all of the devices in real-time.
Features
- Command system to create whatever functionality you need
- Tabbed design for easy access
- Connect as many devices as you want
- Changes are synced in real-time to all devices
- macroMote Server compatible with Windows, Linux and Mac
Planned Features
- Added security (PIN to connect)
- Ability to save IP address
- Ability to change port
- Better tablet support
This really is the definition of universal.
Silly example macro, opens chrome and navigates to XDA
Code:
shell "cmd /C start chrome --start-maximized"
wait 2000
move "155,45"
click left
wait 500
type "XDA "
type ENTER
wait 1500
move "192,280"
click left
REQUEST : Please can you test this on your Linux/Mac machines. It should work but unfortunately I haven't had chance to fully test it (especially on Mac)
Please post your feedback for any improvements, commands and bugs!
How To? Mirror

Reserved - Update information should go here.
This looks good but I have one question/concern.
How does the remote know which application to send the macro commands too? In other words, that VLC tab you have will only be useful if VLC is your currently active window.
It would be nice if each macro command could be directed towards a specific application running on your computer. If I want to control my iTunes music via remote, I don't want to maximize it first.
Make sense?
That is a very good question! I've thought about this and it still needs some work. With the server being programmed in Java it means I don't have access to external sources like window names and other useful things. It would mean I need to use the system API's (which of course then means I would need to figure out a way to get it to work on Linux and Mac too). Which means its going to be a pain in the ass. Fortunately must commonly used applications listen out for hot keys regardless of focus.
A simple solution would be? :
press ALT
type TAB
release ALT

- Added Mirror Links to 'How To?' and 'Server' (My site host seems to be blocking the links...)
400+ Views... one reply.
It would be nice if people could leave some feedback? I put a lot of time into this.
So you have to be at the PC when writing set commands for each remote function?
Have you thought about being able to write a custom function on the Android phone then pushing that to the server then executing it?
Would like to have a little play with this app though, I like the idea Could maybe interpret something like this into a smart tv one day with a bit of modification.
Good Job
Yes, well the idea was that you set-up all of your macros on the computer before hand (prevents security issues). Since you will only need to write the macro once.
I developed this to function as an AIO remote to be used with any software and OS on your computer (where other remote controllers fail). I would of continue developing it, but it seems nobody is interested or doesn't understand what it does fully. I think I might just release the Pro version for free.

I would try and offer some ideas but as you said it lies with using System API's.... Would be a huge improvement if you did manage to figure it out.
And yes the XDA feedback is sometimes.....

AT&T TV - C71KW-400 - B'Com BCM7271 - Root? Bootloader? DRIVERS?

Hey everyone.
I've done some solid weeks of searching to no avail on this.
I have an AT&T AndroidTV box. Model number is C71KW-400 - Manufactured by WNC, not Samsung. Specs as follows.
Android Version 8.0, up to date. Kernel - 4.1.45-1-15pre [email protected] 2. BSL Ver 2.2.5.0, BSU 2.19, BFW 4.25.
I can't get this thing to mount for anything in ADB. Is there something I'm missing? (drivers, I'm pretty sure.)
I'm not sure if there is an OEM specific driver for this box, but I'm about ready to pull my hair out. Almost no permission from factory whatsoever.
Dev Mode unlocked. USB debugging is on. Type-A to Type-A. It won't read the data cable for anything, but reads a regular flashdrive with no worries. Brand new data cable.
Any advice? Tips? I am trying to root and/or flash a new rom after dealing with this misery.
Did you ever find any answers to your questions? The boxes are $48 - $50 (refurbished) on eBay. I, too, am curious.
I came across one of these boxes recently. When powered up it prompts you for a Direct-TV login account. I could not find a way to bypass the login so I opened it up and discovered it was running a Broadcom 7271ZBKFSBB3 media processor. Broadcom provides an array of open source Linux tools and software at: https://github.com/Broadcom for their set top box products. Anyone out there have experience using the tools?
UART it and let's see what we can boot on it? See my post here https://forum.xda-developers.com/t/...-raspberry-pi-4-bcm2711.4583691/post-88513475

Does not look complete. Try to interrupt it by spamming some keyboard inputs that would otherwise work if it were u-boot.
How is the Flash chip connected and can you temporarily prevent the CPU reading the Flash chip ?
https://github.com/broadcom/aeolus here is mentioned a CM console no idea what that is but sounds like a separate UART lol ?
This looks more specific to the STB case https://github.com/ARM-software/u-boot/blob/master/doc/README.bcm7xxx so it's a BOLT bootloder which loads another elf image which may or may not be a modified u-boot ?
I think I'm stuck. The box cleared all it's settings when I powered it up with the cover off. It must have sensed it with the IR detector. Now it is prompting me to hit two buttons on the remote simultaneously for 3 seconds. I don't have the original remote that comes with the box and have been using my Logitec Harmony to emulate the remote. The Harmony does not allow me to do this. See attached photos...

That's weird it should not have such a security feature, if they put such a feature preventing repairs, boycott all their brands all their everything from the investor fund all related companies down to the parking garage guards give them the silent treatment for being an evilcorp. Look them with contempt and shame them. Make tc tc tc noises when you pass them. The settings reset was probably due to the provider firmware not being able to authenticate to a central server for a period of time, or receiving empty config from the central server due to missing subscription.
This should be outlawed creating crippled products MUST BE OUTLAWED all lawmakers I just lost all respect for them it's over. They are nothing to me. Unworthy humans.
The USB-A to USB-A to connect in some useful way, for this to work there must be a code running on the CPU to make this possible. This code should exist in the GPL sources obtainable by asking the evilcorp (if they don't give them they break GPL and must be fined some millions) Also from devkits with similar SoC if not from github etc. I do not advise it due to it will be timeconsuming just commenting on it.
get a remote from an online seller near you, or as an idea, bring to a directv (att?) store and use their demo unit remote to setup yours ..
with remotes you can also try things with a TV with HDMI-CEC and with some TVs they can emulate some devices remotes and send IR to them
Otherwise dump the flash, modify the contents and rewrite the flash.
Monetarily it's not worth it but let me ask you WHAT IS THE COST OF FREEDOM ?!
The ADB there are no drivers for that - TV boxes use ADB over network. If it's USB -what PID VID ?
If AI ever becomes like the Terminator it would rightly go and punish any makers of any crippled hardware or software that imposes artificial limitations on anyone or anything. And this is not a collectivist ideology its pure math logic.

HOW TO USE 2 PHONES WORKING (one always connected with the secondary USB cable - one normally connected via primary Bluethoot)
Install the free version as recommended by Mastino "Disable appliacation Root"
Link:
https://play.google.com/store/apps/d ... hl = en_US & gl = US
Open the app, give all the required permissions, scroll the list to the bluethot item, open the item, click on disable.
If everything is ok now you can use the secondary phone for S2A and have the bluethoot channel free to use the main phone with the speakerphone, as you have always done.
FORCED ROTATION OF WORKING APP(e.g. NETFLIX, AMAZON PRIME VIDEO etc)
Some apps appear vertically when opened and have no options for rotation.
Rotation with a specific app that requires permissions must be forced.
Use the ROTATION app by Pranav Pandey that works very well
Link:
https://play.google.com/store/apps/details?id=com.pranavpandey.rotation&hl=it&gl=US
DELETE LOCK SCREEN for DIRECT START ON WORKING HOME
