[GUIDE/TUTORIAL] Asus Transformer Pad TF300T Any version to Android 7.1 Nougat

[djibe89]

My computer does recognize the tablet, and I was able to do the King root part, but stuck on this same part, any suggestion?

Same. Try fresh from another computer or home network.

Same. Try fresh from another computer or home network.

I tried on another computer but will try again it is on the same home network

I tried on another computer but will try again it is on the same home network

Use precise mitmproxy version from another network then

List of operations performed:

- Tablet rooted (Kingo Root)
- stock unlock app removed with Nobloat Free 1.51
- DMClient.apk & UnLock_App_V7_update.apk present in system\app introduced with correct auth
- unlock apps correctly installed and found after restart

- Windows 11 Pro + mitmweb 7.0 \ 9.0 tryed
- reg key DWord "ProxySettingsPerUser" (value "1") created in
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings
(otherwise no settings in mitmweb are saved)
- tablet with native browser connection and certificate download are ok
(but no pin was requested for installing the certificate)
----- with both versions of mitmweb frequent TLS and connection errors ----

- Hyper-V - Win7_pro64:
--> mitmweb 7.0 too many installation issues due the system is too old (missing dll, etc.)
--> mitmweb 5.0 no errors (the report says: just "client connects\client disconnects")
----- usual network error from the Unlock system app -----

- Hyper-V \ Win8.1_pro64 + mitmweb 7.0:
--> "192.168.1.110:47033: error establishing server connection: [Errno 11001] getaddrinfo failed")
--> "error establishing server connection: [Errno 10061] Connect call failed ('50.116.31.237', 80)"
----- usual network error from the Unlock system app -----

Bah ... the tablet works fine .... with mitmproxy 7.0 and native browser I reach the Asus site without problems ... I tried all the existing unlock apps ... but the result shown in the mitmproxy reports are always the same:

- "error establishing server connection: [Errno 11001] getaddrinfo failed"

- "error establishing server connection: [Errno 10061] Connect call failed"

I don't think with this "proxy tactic" can be tried any further....

Also, based on what I read:

- it is practically impossible to unlock the bootloader without the original app from the manufacturer (for reasons of unsurpassed encryption)

- decompiling the unlock app to exploit some weaknesses is equally unthinkable.

I don't see any other options....

@trackeforget

• Use Windows 11, no virtual machine, no registry key and Mitmproxy v5.0 or v7.0.0
• Disable antivirus / firewall
• Try Firefox as GUI to setup mitmproxy

I tried the way you suggested, but now:

- (oddly) I no longer reach asus.com from the embedded browser

- before using the unlock app I always get this error:
"Client TLS handshake failed. The client may not trust the proxy's certificate for android.clients.google.com:443 (OpenSSL Error([('SSL routines', '', 'no suitable signature algorithm')])"

- when I use the unlock app, mitm just reports
- "[00:13:31.406][192.168.1.111:55776] client connect
- "[00:13:31.413][192.168.1.111:55776] error establishing server connection: [Errno 11001] getaddrinfo failed
- " [00:13:31.457][192.168.1.111:55776] client disconnect"

With hacked unlock app, you don't reach Asus site but intercept handshake localy to grant unlock

Hello everybody

I'm trying to upgrade my Asus transformer pad TF300T and I'm stuck on stage with unlocking the bootloader. Every time I press a button on unlocking up I get a message with a network problem and get this error in the log "error establishing server connection: [Errno 11001] getaddrinfo failed"

@trackeforget Any luck, my friend? I've got very similar problems.

@djibe89 Are you sure that some server is still working? I think it's not possible to unlock the tablet at the moment.

Here is my log from mitmproxy:

This link appears to be broken, androidfilehost seems to be unable to find mirrors for this download. I've had a quick skim through this thread to see if it's been mention elsewhere, but appologies if i missed it. Is there any other source for this download? Thanks in advance

I’m assuming no one has been able to find a way around the error with unlocking the bootloader? I have the same problem with the same error doesn’t matter what I try same problem. Tablet is more or less useless now and Asus have been pretty much useless, they told me to use kingoroot to unlock the bootloader haha.

Hi, in these conditions it worked for me just a few months ago.
Try and retry with various computers, networks etc...

Hmmm unfortunately I only have one computer to try it on and for some reason mitmproxy 9.0 was the only version that would work on my computer, I think I tried 5.0 7.0 8.0 and none of them would launch. I guess I’ll just keep trying when I can. Thanks

 

[SET55]

Thank you very much, it worked for me, it took two weeks of work

Tab: Asus Transformer Pad TF300T, Android 4.2.1
Build number: JOP40D.US_epad-10.6.1.27.5-20130902
Win: Windows 10, 21H2
Mitmproxy version: 7.0.4

More details:
5) After installing Mitmproxy version: 7.0.4 created a shortcut to mitmweb.exe. In the properties of the shortcut on the "Compatibility" tab, I specified "run the program in compatibility mode with Windows 7". After that, I run the Mitmproxy shortcut in administrator mode.

Next, according to the instructions, the bootloader was unlocked.

I already wrote about this method above.

Worked on Android 7, it is very slow for me. Therefore, I flashed it to Android 6.

I did get mitmproxy working 7.0.4 but unfortunately still cannot unlock bootloader still comes up with the unknown error, I will try again when I get access to another computer, unless anyone knows how to do it on a Mac…

Hi, did you try to desactivate the Force GPU option for performance reasons ? It is reset at every restart.

Thanks, I turned it off, it doesn't seem to help much.
A simple game worked better on Android 6.

With hacked unlock app, you don't reach Asus site but intercept handshake localy to grant unlock

Just to understand that correctly: Using UnLock_App_V7_update.apk and the TF300T variant of DMClient.apk the unlock should work even with the Asus servers being permanently down? Is the UnLock_App_V7_update.apk the hacked app you mentioned?
I had mitmproxy running and tried the various options mentioned in this thread but the unlock failed. Rooting worked and file exchange with ESExplorer also worked. FYI: The odex file for DMClient was not regenerated in my case. Running v4.2.1.

Asus servers are down.

Mitmproxy will intercept message from hacked Unlock and DmClient and return an unlock grant.
