Hi,

I'm not able to complete step 6, on the tablet it keeps saying: "verification with proxy failed". It won't load the mitm.it site. What can I be doing wrong? I'm using my company laptop which is on a domain normally. But i also have a private account on it.

Best regards, Sander
[Transformer TF300T General] djibe89:
Hi,

You used the modified Unlocker v7 ? Changed permissions ? Used mitm version 5 ?
[Transformer TF300T General] Sanderman1:
I'm not even able to come that far, I tried MITM V5 and V7. I get stuck at the step "go to mitm.it", so I didn't even try to run the unlocker. The browser then already comes with the notification. On the both the dcm client and the unlocker I changed the permissions. Is it correct that there is no unlocker in the directory that I need to put it in? It should be the same directory as the dcm client, right?
[Transformer TF300T General] djibe89:
Hi, unlocker is in my pack. Have you checked that laptop antivirus didn't block it ?
[Transformer TF300T General] Sanderman1:
I did everything as the manual stated, so I also got all the software you mentioned, including the unlocker ;-) I checked the antivirus, couldn't see anything about any blockage. I just discovered that i can pause the firewall haha, so i'll try that this evening. I'll keep you updated!
[Transformer TF300T General] Loaish:
Hello, I'm new to changing android and everything that the process entails. I wanted to express my case since I still can't find a solution, I currently use Windows 10 and I can't advance from stage 2 since I install the Universal Naked Drivers but it doesn't work since I connect my tablet with its respective original cable to any port USB from my computer, but my laptop does not recognize the device. How could I do?
[Transformer TF300T General] Sanderman1:
I used another laptop with disabled firewall, and it works 😄 Installed Android 7 😀 Still a bit slow though. Any tips on making it even faster? 😉
[Transformer TF300T General] pigeta:
Did u try on another computer?
[Transformer TF300T General] Loaish:
Hello, thanks for your answer, I thought nobody was going to answer me. Yes, I tried in another computer that have Windows 10 like operating system.

Is it possible to get the Unlock apk also for the Asus 301T? With the apk from this thread it says unsupported device. It should be the same hardware though.
[Transformer TF300T General] ares-ex:
I am stuck here. I am at number 6 with mitmproxy and i got it to work but when i want to unlock tablet or go to asus.com this is what i get: Client TLS handshake failed: i cant unlock the tablet. i can open almost any other web page but asus.com just wont connect. i tryed 3 versions of unlocker v7,v8, and tf701 in some hopes it will work but its not happening. Did Asus fked something up with their page what is going on here? I even registered my device on their page with serial number i have no idea what else i can do to get this thing to work I just want to unlock the damn thing and update it to Android 7.
[Transformer TF300T General] Picklejar:
Fastboot can't see any devices.

Installatiion of the drivers seemed to go well. But after installing the drivers Windows saw the Transformer sometimes, sometimes not. And when I tried to copy files to the Transformer, copying started... then ended without any result or error message.

After reinstalling the drivers several times, Windows doesn't see the Transformer anymore, regardless whether it's started up or in Fastboot mode...

Other USB ports don't help, Admin Command Prompt doesn't help, etc.

Maybe my cable is broken? I've ordered a new cable.

If anyone has an idea, I'm all ears :-)
[Transformer TF300T General] agiiii:
hey!

First of all: HUGE THANKS FOR THE DETAILED MANUAL!

And now not so optimistic comment :(

I am stuck in bootloop after wiping tab, and installing KatKiss with GApps. I didn't install magisk.

Tab is disconnected from the PC, has charger plugged in, reacts to keys, but the system won't load. Only Asus logo going on and off the screen.

I've been fighting this for 2 days - wiping and reinstalling KatKiss, but no luck.

Any ideas?

But every time the tab told me that the unlock not happened ant i should try it again.

Today i have registered it at ASUS but no chance to unlock it.

I hope anyone can help me. The Tab works good and i want to use it only for a home automation display.

I am nearby that i demolish this tab and buy me a new one.

Thanks for every input where it would possible that it helps.

I found the problem is the version of mitmproxy i had 9.0.1 after uninstalling a used 7.0.0

i unlocked it using version 7.0.0

EDIT: Thank you SET55, this Mitmproxy v7.0.4 and Windows 7 compatilitiy mode worked for me and finally went trough all other obstackles!

Hi all, I see there are couple of users with unlocking problem (point 6 of your guide). I have the same problem with Mitmproxy and unlocking. Ss lets go step by step.

Tab: Asus Transformer Pad TF300T, Android 4.2.1

Build number: JOP40D.WW_epad-10.6.1.27.5-20130902

Win: Windows 10, 22H2 (latest patch applied)

Wi-Fi: on Private mode

Other SW: from your pack v3

Mitmproxy version: 9.0.1 - on tablet once run Unlock Device app it says unknown error. This may be a network error. Please wait and try again later.

on Windows browser mitmweb says 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')]))

Users advised to use Mitmproxy v7 or v5 to get rid of the TLS handshake error, but both v5 or v7 give me these errors (I could not open properly Mitmproxy on Windows browser). Error screen below:

Mitmproxy (both Edge or Chrome)

mitmproxy has crashed.

In summary: with Mitmproxy 9.0.1 it works, but I have TLS handshake error. With Mitmproxy v5 or v7 Mitmproxy not working in Windows browser as above stated.

I dont have other notebook to try, just desktop without Wi-Fi but I assume there is some small part missing to get it work.

Could you please help?

Thank you.
[Transformer TF300T General] ritap:
hello, thank you a lot! the guide works great provided you use an older version for the proxy (can't tell why).

TWRP app keeps asking for an app update in the notification, is that safe?

Sorry if I posted in tf700 thread, I don't find a way to delete that post.
[Transformer TF300T General] 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.
[Transformer TF300T General] errhec:
Is there still possible to unlock the bootloader?

If I use the Mitmproxy 7 I get following:

192.168.2.78:60414: client connect

192.168.2.78:60414: server connect mdm.asus.com (123.51.152.19:443)

192.168.2.78:60414: server disconnect mdm.asus.com (123.51.152.19:443)

If I use Mitmproxy 9 I get:

::ffff:192.168.2.78:45096: Ignoring server verification error, continuing with connection

Setup 7.0.0 as stated.

Try again.

Try on another PC
[Transformer TF300T General] errhec:
I try on linux and windows pc. Same result.

I will try on third (windows)PC.
[Transformer TF300T General] djibe89:
You are using the hacked unlocker app ?
[Transformer TF300T General] errhec:
Done, it is still possible.

I reset the tablet and go again, step by step.

(while doing, i think that previously I forget to set the permission for unlock app, it was set to 666 and I change it to 644 )

I use almost all from your pack (https://www.androidfilehost.com/?fid=17825722713688260169 )

No problem.

Android is Linux and debugging tools come from this platform.

But I won't be able to help you
[Transformer TF300T General] errhec:
It should all work, maybe it will be a problem with mitmproxy ?? Try it.

djibe89 i follow the tutorial, GPU rendering is not checked. It seems that is slow only when accessing the settings, when you use app is quite good. Newpipe (noadyoutube) is also working.

Thank you again for the effort you (and other) put into developing.

For anyone having trouble unlocking their device: I have written a follow up in a different thread after having issues with unlocking a TF300TG. I falsely assumed that I could just use the latest firmware for TF300T mentioned in the guide, which apart from breaking many features (USB connection to PC, including adb and MTP stopped working completely) also seemed to break the unlock process of the modified UnlockApp.apk.
[Transformer TF300T General] Galmo13:
Hi. I've been trying to follow your tutorial, everything went pretty smoothly until I tried to unlock the bootloader. I had no problem with the proxy, I downloaded the certificate, but when I tried to launch the app ("Unlock Device Tool V7, the one from your zip) it said "Unknown error occured". I saw with mitmproxy that there was some tries to connect to Asus server. There is a text file linked with what mitmproxy said during the try. I think it's not that complicated to fix (although I did do everything about setting up the proxy like you said) but I don't know a lot about proxies and stuff. I did download the certificate on the tablet, and attempted multiple soft resets of the tablet, but it was all in vain... Many thanks in advance for anyone who will reply to this, and for all of those who keep those old hardwares alive !
[Transformer TF300T General] errhec:
Did you set the premission also for UnLock_App_V7_update.apk. ??

Did you use mitmproxy 7.0 ?

Follow the steps as is described in tutorial.
[Transformer TF300T General] Galmo13:
Yes, everything you said was done. I was working with a 4G connection with my phone, so it could be that. The tablet couldn't even load asus.com website due to chrome being too old. However, after switching to a standard Wi-Fi and installing Opera mini, it worked just fine, but thanks to you
[Transformer TF300T General] Ju5t3nC4s3:
Dns. Always the dns..lol
[Transformer TF300T General] beerpass:
I'm having issues with unlocking the bootloader as well. I was able to follow along pretty easily up to that point, and I'm not sure where things are going wrong.

Here's every step I took so far:

Downloaded all files, installed drivers on my laptop, it recognizes the tablet and can transfer properly.

Rooted the tablet, had to use the Windows app to do so but it worked and is definitely rooted.

Copied DMClient and Unlock_App apks to the appropriate folder, changed permissions as listed, restarted tablet.

Installed Mitmproxy v.5.0.0 because v.7.0.0 refused to open on my Win8 laptop. Changed the settings as listed, except for the tls_version_client/server_min settings because they weren't in the menu. (This might be where the issue is, but I can't figure out how to fix that if the setting isn't even there to change.)

Changed the PIN on the tablet, changed the proxy settings to match my laptop IP, downloaded the certificate properly.

I know web traffic is going through the proxy as it should because I can see the log update whenever I open a website or an app. When I try to use the unlocker, however, I see a clientconnect followed by a clientdisconnect three times in the log before I get the "an unknown error occurs" message popping up on the tablet screen. I tried to change the ssl_version_client/server settings to "all" instead of the default "secure" to see if that would have an effect, but no such luck.

I've done a hard reset a couple times and started from the beginning (skipping the root since that's already done), but it still won't work. Both the laptop and tablet are connected to the same wi-fi, so there's no issue there. Laptop is set to private network as well. Turning off the laptop's firewall had no effect.

Is there something I'm missing with v5.0? Is there any way to get v7.0 to work on Win8? Any other suggestions as to what I'm not doing right?

Hello.

This guide has obviously helped a lot. But like some members, I also encountered the inability to unlock the bootloader. I have tried different versions of mitmproxy but failed every time.

At the moment, the mitmproxy event log outputs the following when trying to unblock:

192.168.30.17:51102: error establishing server connection: [Errno 10060] Connect call failed ('123.51.152.19', 443)

192.168.30.17:51104: client disconnect

I also noticed that when setting the proxy address in the wireless network settings, there is a warning: The HTTP proxy server is used by the browser, but is not available to other applications. But for unlocking, just another application is used - Unlock Device Tool v7.

Maybe someone has a solution to this problem?

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
[Transformer TF300T General] trackeforget:
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
