To my opinion you might be in the wrong thread with your questions. I would like to recommend to to go to this one:

https://xdaforums.com/transformer-tf300t/development/rom-t3453702

If you should decide to use Nougatella #19, after reading post #1 there, you will find in the first line of the install instruction "You need Kang TWRP 2.8.7.2" (not another version of TWRP!). Then follow the install instruction carefully step by step.

Further on you should have a look at this post: https://xdaforums.com/showpost.php?p=71094836&postcount=615

There is also a video about the custom rom on the TF300T, made by the developer Timduru itself.

Finally it's up to you, if you are willing to bring your old TF300T to a new life. The device is it worth, really! :cowboy:

Bootloader version

Hi

I want to upgrade my TF300TG to Android 7 and see that

your BOOTLOADER MUST END IN 27.1 or 27.5.

mine is : WW_epad-10.6.2.11-20131213 A03.

Do I need to downgrade in order to perform Os upgrade ?

[Transformer TF300T General] ebonit:

As far as I know "Matchless 2015" is one of them with a lot of positiv experiences as you may see here: https://xdaforums.com/showpost.php?p=71492577&postcount=738 .

Good guide, newest updates working fine here!

Thanks for this guide OP.

TF300T was my first Android tablet, got loaned around a few times over the last several years and finally came back to me with CM 11 installed. A quick look on XDA shows KatKiss to be the current science for this device. So after reverting to the latest stock ROM to get BL v27.5 I went ahead and used the very latest pieces I could find to rebuild from scratch:

Official TRWP 3.1.1-0 recovery (announced here)

Stable SuperSU v2.82 (announced here)

Latest Open GApps Pico for Nougat 7.1 on ARM (available here)

First attempt got majorly screwed up by mistakenly wiping the wrong things with the wrong tools... :o

I used the tips in this post to recover from that mess. Had to paste the entire set of fastboot erase commands into the shell all at once, otherwise commands would time out before I could get the whole thing wiped clean. After it was completely wiped then I used fastboot to push the system blob from the latest stock ROM and was finally able to return to the business of the KatKiss upgrade...

BTW your Transformer Pad TF300T pack was really helpful. I had the latest Android SDK platform-tools but for some reason they weren't talking correctly to my pad. But these are on a drive other than C: so there might have been a PATH issue at play. In any case, running your pack from a short no-space path on C: did the trick.

Did not need to install the Naked Drivers. This is Windows 10 (latest build) and the OS managed to find and download from WU some drivers labeled "ASUSTeK COMPUTER INC. 3/16/2015 8.0.0.3".

Formatted both /cache and /data as F2FS via TWRP 3.1x, per your instructions.

It's like a brand new tab! All I need now is more dpi. :eek:

-------------------------------

I followed step 1-6 without any issue. But I'm struck at Step 7. After reboot its continuously failing with "unfortunately setup wizard has stopped " message. Not able to proceed any further with configuring tablet. No setting screen available with this.

Can someone help?

[Transformer TF300T General] WycombeWasp:
I have just "inherited" a little used TF300T.

It is "as bought":

Android: 4.0.3

Kernel: 2.6.39.4-00003-gafee6c5

Build: IML74K.WW_epad-9.4.3.30-20120604

It works OK, but is well out of date.

Thought I'd try to update it, but everything on ASUS site is for later versions.

Tried system update, but keeps failing. Says try again, but won't let me try until I have powered down, and then get same message again.

Now I don't understand a lot of what is written in the thread above, so can someone explain, simply, if I can upgrade, and how to go about it?

Well, it comes from the mitmweb transfers/connections/setup.

You may try from another computer or local network
[Transformer TF300T General] modernjoker:
I'm stuck at unlocking the bootloader. It gives the error message "an unknown error occurs, which may be a network connection issue. Please wait and try again later."

Any suggestions?? I'll try from another computer and see if it gives the same error.

I do not see the unlock app trying to connect in mitm on my computer, the last connection I see is when I went to mitm.it from the tablets browser? Could this be the issue?
[Transformer TF300T General] djibe89:
"an unknown error occurs" means your local network proxy or settings are not yet suitable.

Hello djibe89

I followed your tuto (a while now: Feb 2017 !!!). Every steps worked perfectly... Until end of Step 9:

"

Android 7.1 is installed.

When done prompts, tap on Wipe Cache/Dalvik and swype to confirm, wait.

Disconnect tab from PC.

Then Reboot System.

Let the tab start (long time).

"

From there the tablet TF300T, is continuously restarting :

It show on the top left: The device is unlocked

And in the middle, the "Asus, inspiring innovation etc..." and after some seconds, it restart again and again.

I can press hold Power + Volume- until you see 3 icons... And get access to TWRP... But whatever I do I fall in this restart...

Did you ever had this case ? And do you have a solution for this ?

Many thanks
[Transformer TF300T General] djibe89:
Hi @MHa67 , clear all partitions from TWRP, flash Android alone. Reboot. Does it work ?
[Transformer TF300T General] MHa67:
I think maybe I found the problem: The tab is TF300TG and not a TF300T.... But is that mean your tutorial will not apply for the TF300TG ?

For your question:

Do you mean if I found a TF300TG Rom ? (Something else than TF300T Latest Rom Version: KatKiss-7.1_TF300T_039.zip ?

Unfortunately, I didn't find anything... By the way I'm not a specialist (like you) of the android word. So please could you be more explicit in your responses. I know, to be more accurate, takes more time... But you're talking to a beginner...

Again thank you for your great job, and thank you for your support.

For now, I'm stuck!!! (Just at the finish line :-()
[Transformer TF300T General] MHa67:
Hi

After reading some post here on xda-developers... I understood that TF300TG take in charge 3G... (Sorry I'm newbie, so I need time to understand !!!).

But couldn't be possible to run TF300T Rom (KatKiss_7.1), without 3G support...?

Because I don't really care about it

Or this will lead to hardware issue and avoid my Tablet to start (as I'm experimenting now) ?

Worked for me :)

Hello everyone !

I started following this tutorial 1 month ago (yep, I couldnt do it all in a row as I encountered so many issues and had a lot of kids interruptions x)) and finally manage to get my TF300T on Android 7.1 today :D Yipee \o/

A few informations about the problems I had :

- I wanted to do the manipulations from a Windows 7 computer, so obviously, things went a bit nuts for drivers installation (figuring out how to disable driver control, then install and in the end : realising at the moment of the fastboot that it didnt worked x)).

- I also couldnt make mitmproxy to work on windows 7. It kept having issues and couldnt start.

In the end (after about 10 hours of work) I gave up on windows 7 and took a windows 10 computer for the manipulations and things went perfectly smooth (except for the drivers. It still took me 2 hours to make then work x), by trying the advices on pages 1 and 2 of this thread).

I also had trouble getting into bootloader mode (pressing power and - sound button) because I wasnt pressing them while screen was dark, and it took me numerous attempt to understand how to properly do it.

Besides that, everything was perfect ! This is a great tutorial, very clear and easy to follow thanks a lot :)

Cannot download my favorite apps on play store :(

However, I am now facing a very different issue : when I go to the play store, I cannot download my favorite apps (1 game and Netflix). They are not shown within results, and if go use the internet link to get them (like : https://play.google.com/store/apps/details?id=com.netflix.mediaclient&gl=US) I get the "not compatible" message.

Same goes for Disney+.

I dont understand why, because for instance, my favorite game requierment's is said to be "android 5 or +" and I am pretty sure 7 is superior to 5 ;) It should be fine... and as the tutorial says Netflix and Disney+ should work, there is definitly something fishy on my side.

Is there any specific tips about how to get netflix, disney+ and recent apps on this rooted tablet ?

I am THIS CLOSE to be able to enjoy the result of this month of work ! Please let me know guys if you encountered this issue and how you managed to fix it :)
[Transformer TF300T General] Valgio63:
Good morning and sorry my bad english!

I moddated my TF300T with timduru rom.

I'm trying to format an SD card as system storage, but it stays fixed at 20%.

Am I too quick or is something not going?
[Transformer TF300T General] Space Gate:
Thx for the Tutorial!

I was really struggeling with the mitmproxy, which gaves me always an certificate, ssl, etc. error.

Finally tried the 7.0.4 Release which worked for me(win10) from this website:

https://mitmproxy.org/downloads/

with following options:

block_global = disabled

showhost = enabled

ssl_insecure = enabled

tls_version_client_max = UNBOUND

tls_version_client_min = UNBOUND

tls_version_server_max = UNBOUND

tls_version_server_max = UNBOUND
[Transformer TF300T General] Trigve:
Hello,

I've got TF300TG and have tried to use this guide, but as many has stalled on unlocking the bootlader. I've replaced the apps, installed and configured the mitm etc. etc. but when unlocking the bootlader it shows the "unknown error/network error". In mitm log there is this OpenSSL error:

Client TLS handshake failed. The client may not trust the proxy's certificate for mdm.asus.com:443 (OpenSSL Error([('SSL routines', '', 'no suitable signature algorithm')]))

So it looks like it's the problem with the TLS version.

Anyone has advice if it could be somehow solved?

Thank You
[Transformer TF300T General] djibe89:
Hi, this ROM maybe doesn't have prerequisites for Netflix and Disney latest versions.

You may have to look into Magisk root (v23 or v24.1).
[Transformer TF300T General] djibe89:
Hi, I don't know if your DMClient has been approved for TF300TG unlocking.

Are you using Windows 10 ?

Tried from another computer ? Or LAN ?
[Transformer TF300T General] Trigve:
I'll try another DMClient version I found for the TG.

Yes, using Windows 10.

The communication is working with mitm so I don't think it is network problem (I've tried using wifi and ethernet).
[Transformer TF300T General] stepholo:
Hi,

I'm still blocked my trying to "unlock" my TF300 with the "Asus Unlocker V7 Update".

Mitmproxy is well running and I see the requests of the tablet.

I always receive an "Unknown Error" message witch a network trouble reported........

I don't know what to do regarding at all the steps I've respected.

I've followed the tuto step by step.........

I already spend a lot of time ans I don't know what to do........

If someone has an idea ;-)

Thanks

[Transformer TF300T General] djibe89:
Hi Stephane, you could try mitmproxy from another Computer or another LAN.

Hope you'll succeeed
[Transformer TF300T General] Trigve:
Ok, success finally.

So, I was searching around regarding the OpenSSL errors and was also tweaking the mitm config. And there was a weird thing, that min/max client/server TLS version was "behaving" weird in the sense that they were somehow connected (i.e. changing client version was spewing errors about server and vice versa).

Then I looked on mitmproxy on github and found that version 7.0.1 contains something like "Performance: Re-use OpenSSL contexts to enable TLS session resumption" so I was thinking maybe the SSL context is reused with wrong TLS version on client/server. So I downloaded the 7.0.0 version and then it worked. One should also remove the old mitmproxy cert and try to download a new one (mitm.it). DMClient is from this thread as all others SW ( except the mitmproxy, of course).
[Transformer TF300T General] stepholo:
Hello,

Maybe my problem come from the version of the tablet which is a "TF300TL".

Do I need a specific DMCLIENT dedicated to TL version?

Thanks
[Transformer TF300T General] djibe89:
Hi, I'm sorry I don't know this model.

Please share your success with us.
[Transformer TF300T General] stepholo:
The TF300TL is the 4G version.

The "TG" version was for 3G.

Hi all,

first of all, thank you @djibe89 for the amazing guide!

I wanted to note that I managed to follow this guide successfully to update and root my TF300T in August 2022. My tablet was already unlocked, already had TWRP recovery 3.3.1 and an older version of the KatKiss 7.1 ROM.

However, I spent a lot of time struggling to get root with Magisk. I tried both flashing the zip via TWRP and the boot.img patch route, unsuccessfully. I finally managed to get it to work by using the exact same versions as in the package provided by djibe89 (TWRP 3.4.0-0 and Magisk 23.0). Initially, I had tried to upgrade to the latest TWRP and the latest Magisk, but no matter what I tried, I would end up with "Installed N/A".

If anyone is having this issue with Magisk, try to use the exact versions above. Also, not sure if it matters, but just in case: I installed the KatKiss zip and the gapps first, wipe Cache/Dalvik, let the tablet boot for the first time (making sure to disable wifi to get past the wizard), then back to TWRP to install Magisk, forgot to wipe the cache, booted to system only to see Magisk was not there, then back to TWRP to wipe the cache, then booted to system again, this time the Magisk placeholder was there. It asked to install, I allowed, and finally I had root :)

Hope that helps someone!
