First of all download "Minimal ADB and Fastboot" and install it on your PC. Then power on your TF300T and hold "Vol down" at same time. Three icons RCK, ANDROID and WIPE DATA appear on the screen. Don't pay attention of it. However in the left above corner the notice "Starting Fastboot USB download protocol" appears. So you may connect the tablet with your PC via USB.

Open “Minimal ADB and Fastboot” and put in "fastboot devices". The device should appear as "xxx device". This is your serial number. After that you may do a Buster99 step by step.

Please don't touch the WIPE DATA icon. You'll brick your device for good!

You were way faster than me! That is the information I was looking for. It ha s been a long time since I had to use these steps :D
[Transformer TF300T Android Development] Cr4ck86:
I didn’t explain myself well, definitely. I touched yesterday that damn icon accidentally, so now I’m in this situation due to that.

Now, running the [FWUL]adb/fastboot without any installation and driver issues [v3.1] in other computer, I managed to write the command “adb devices” and get some answers: the serial number and the message that is connected into the recovery, as you can see here. h t t p://imgfz.com/i/KFRJu9j.jpeg

I tried other commands, adb and fastboot, and I don’t get any answers, just error messages. h t t p://imgfz.com/i/mzfeR1T.jpeg

I also tried with the Minimal ADB Drivers in my Windows PC, and it was fruitless as well, like the previous times I tried.

(Excuse me for the links, I'm not able to post links yet).
[Transformer TF300T Android Development] ebonit:
When you are on the screen with 3 icons you are in the bootloader and fastboot mode! :cowboy:

If you cannot get into the bootloader by holding the Volume Up and Power buttons the device is bricked for good! - sorry.
[Transformer TF300T Android Development] Cr4ck86:
So, do you think I have to bury my tablet, or is there any hope?
[Transformer TF300T Android Development] gc2712:
Perhaps I am misreading the screenshots you posted links to but the first one suggests that ADB is working and showing a device identifier? The second one shows you have the "your own command" radio button selected instead of the "fastboot" button. I use Linux so I am not sure what gives you fastboot commands in the Windows environment. Does it require admin access to run?

If, in fact, adb is registering your device on the PC then you can (re)install TWRP recovery via adb using this link https://www.xda-developers.com/how-to-install-twrp/ .

But perhaps try "adb reboot bootloader" first and see if your tablet reboots into fastboot mode. [MENTION=7106193]ebonit[/MENTION] is definitely the goto person when advising on 'sort of' (semi) bricked devices for the TF300
[Transformer TF300T Android Development] ebonit:
Yes, there is! This tablet is it really worth to be rescued by exchanging the mainboard.

Please read carefully the thread by [MENTION=1968194]huebinger[/MENTION] about how to replace the mainboard https://xdaforums.com/showthread.php?t=2368372.

For TF300T mainboards there are different offers on ebay.com in a range of 20-30 USD.
[Transformer TF300T Android Development] Cr4ck86:
Thanks for your answer. You're right, the computer I was using with the Linux utility is the only one that showed me the device identifier, but I typed other commands and they didn't work at all. I can't reboot the tablet into fastboot mode, I tried it several times and it was impossible.

Do you think the TWRP solution via ADB that you say would work? I didn't think that was possible, I'll give it a try.

After reading you, I'm creating a Live USB with Linux to try the ADB commands from it, just in case. I hope I can see the device identifier again and do anything with my Transformer.

Wow, I haven't thought that! It would be difficult, but I think it's the last chance to rescue my tablet after all. I will do a search on ebay to see what options I have here in Spain. Thank you very much [MENTION=7106193]ebonit[/MENTION]!

I hope it works for you. Otherwise [MENTION=7106193]ebonit[/MENTION] suggestion of a new motherboard may be the only way restore your tablet. Do let us know how you go.
[Transformer TF300T Android Development] ebonit:
You are welcome! Using the thanks button is greatly appreciated.

To be finally sure your device is bricked power it on together with holding Vol down. If the notice "Starting Fastboot USB download protocol" and the 3 icons don't appear the brick is ultimate.

Hello everyone,

I have to tell you right away that I don't have a lot of rooting experience, all I have rooted is my Samsung Galaxy S about 10 years back ...

I am completely fed up with those annoying standard apps and I feel that my tab is getting very slow, even after a factory reset, among other things loading websites takes a long time, so last weekend I tried to root my tf300t (with motochopper) to install the Katkiss 7.1.2 rom, but sadly with no succes, I soon figured out that I updated it a while ago to android 4.2.1 so rooting doesn't work.

I then tried several other things described in (old) forums and youtube, tried to downgrade to 4.1.1 but all with no succes, I have spend about 5 hours on it now...

Is someone willing to describe step by step what to do, what do download for my windows laptop and what to do with the tab?

I've already saved everything I need from the tab so no need to describe that point.

specs tab:

android 4.2.1

Build 10.6.1.27.5

specs laptop:

win 10

64bit

Tnx, hope someone can help!?

Regards

Jeroen
[Transformer TF300T Android Development] gc2712:
Not sure why you think you have to downgrade to 4.1.1. I assume you have already unlocked the bootloader correctly and have ADB installed on the PC? If so, You should be able to just follow the instructions in the Original Post.
[Transformer TF300T Android Development] blurky:
Thanks for the reply.

I tried to install ADB but it doesn't do anything, just opens CMD for a second and closes it...
[Transformer TF300T Android Development] ebonit:
Be happy that your device is on the latest ASUS firmware. With your knowledge keep the hands off of any changes. Never change a running system! The TF300T will be bricked easily by lack of knowledge.

First of all reduce the amount of apps on your device as less as possible. That will increase the performance and you will have more fun..

After that go through this Guide/Tutorial https://xdaforums.com/transformer-tf300t/general/guide-asus-transformer-pad-tf300t-stock-t3554744 very carefully step by step. In any case you need help you will find it!

Good luck!:cowboy:
[Transformer TF300T Android Development] blurky:
Thank you very much, didn't found this step by step thread yet...:eek:

I did the step by step thing and came to step 5, and now there is an issue:p

From here the tab says there is only 56mb free space on the micro sd.

I have 2 4Gb class 10 micro sd's, on one of them the rom files, and the other I had lying around, formatted an extra time to fat32, checked the free space (3,66gb) so that must be enough, but on both sd's it says only 56mb free space.

I tried a reboot of the tab but that didn't work..

What to do now?

[EDIT]

I tried checking "disable free space check before backup" option but then after "swipe to backup" it says

"Can not create '/external_sdcard/TWRP' folder (I/O error)

Failed to make backup folder.

Seems it can not read/write the sd-card...?
[Transformer TF300T Android Development] ebonit:
The tablet TF300T is available with 16GB or 32GB internal memory. There is also one slot for a micro SD card with minimal 16GB or better 32GB external memory. Keep in mind, this is basic knowledge!

Your SD cards are useless totally because of the less capacity. Put a 32GB SD card in the slot. Then your TWRP backup will end successfully. No issue anymore!
[Transformer TF300T Android Development] blurky:
Thank you, at the moment you wrote this I found a 32Gb sd card, tried it and indeed it began backing up, but sadly after 2 min gave an error.

Am now slow formating the 32gb and trying again..

To be continued..

[EDIT]

It seems to work, tab is now booting the new rom :D

Thank you very much ebonit!

P.s. about the only 16 or 32gb card thing... I didn't know that ;)

Dear [MENTION=3951330]timduru[/MENTION] and [MENTION=7106193]ebonit[/MENTION],

thank you for all support and releases.

I have been troubleshooting the revision 039 with my tf300t for 4 days. I have big issue with WIFI tethered from my phone (channel 13).

specs:

I followed post n.1 with:

- KANG TWRP 2.8.72 ( however I also tried with 3.3.1.0)

- 039

-arm 7.1 Pico (I tried also some older version)

-Super SU 2.82

Wifi does appear sometimes but with limited speed (i.e. 0,1 KB/sec). I read already all post and tried to change all regulatory domain region.

I have my neighbor with a router wifi (tested to be in channel 6) and with that connection works fine. I tried to change channel to my phone but due to this android release it is not possible without rooting (xiaomi redmi note 8pro). I dont know aymore what to do..please help
[Transformer TF300T Android Development] ebonit:
Please note, you don't have a big issue with that ROM. The culprit is the wrong channel. In the past there have been similar problems from time to time depending on different regions. In Europe for instance channel 12 and 13 work fine with this ROM. So keep away from channel 13 and either stay on your neighbors channel 6 or connect the tablet to your own router. If you need to know more, please search this thread for "WiFi channel 13".

PS:

You may also try: Settings -->advanced -->change WiFi regulatory domain -->select EMEA and Rest of World !

"Hello!

I remember you helped me a lot lately with my Transformer, even though I didn't be able to turn it alive again.

Yesterday I got a new ASUS Tf300 and I want to install the Nougatella ROM now, but I'm stuck when trying to unlock the bootloader. I downloaded the Unlock V8 tool, but it says that it only works with Android 4.2, and I realized I'm in 4.1.1, so the file doesn't work at all. I registered my device on the ASUS website, but I can't still unlock the device. What should I do? Could you help me, please?

Thanks a lot in advance.

Best regards."

[MENTION=10641841]Cr4ck86[/MENTION]

Thanks for your private note above! Yes, I can help you by advice.

Please upgrade your new device with the last ASUS firmware (stock rom Android 4.2 Jelly Bean). After that you may unlock the bootloader ending 27.5 without issues.

Go to ASUS website and download "WW_epad-user-10.6.1.27.5" and do the upgrade like recommended by ASUS.

Good luck! :cowboy:
[Transformer TF300T Android Development] gamervishal:
Thanks for the ROM. Worked like a charm with TWRP 3.3 and latest Magisk (instead of SU).
[Transformer TF300T Android Development] Cr4ck86:
Thanks a lot! I've just upgraded the device and now I'm on the bootloader ending in 27.5, as you said. Whenever I try to unlock the bootloader now, the app says there are some problems, and show a message like this: "An unknown error occurred, which may be a network connection issue. Please wait and try again later."

I search that on the Internet and found that it's pretty common, and it's a problem with the ASUS servers. What should I do next? Just wait until the ASUS servers accept my device? I already registered it, so I don't know what to do (apart from waiting, of course).

Thanks in advance for your help, again.

Don't forget firstly to deactivate your Google account on the device! It's very important
[Transformer TF300T Android Development] Cr4ck86:
I read the thread you said and others in this forum, but the problem still persists. I phoned ASUS and they told me that they provide now the tool for unlocking, but there's no more they could do about it. I registered the device with the SN on the website with my personal account. Either the v8 or the v7 unlock tools keep showing the same error message.

I tried doing a factory reset, skipping the Google Account step, enabling "Unknown sources" and USB Debugging to install them...nothing happens, only the message.

I don't know what to do next, because I read the only way to install a custom recovery and KatKiss ROM is by unlocking the bootloader. Am I right?

Thanks a lot.
[Transformer TF300T Android Development] ebonit:
"Please note, V8 does not install at all anymore. V7 will install if you allow "less secure apps" in your Google account settings. On the web - not your Google account on the tablet.

Delete the Google account from the tablet (Settings > Accounts), then run the tool again. If that doesn't do it, do a factory reset from Settings, reboot and during the initial setup establish a WiFi connection but skip the google account setup, then run the tool.

This can be a 5 Minute operation that goes without a hitch or a very frustrating experience with lots of error messages. There is no definite rhyme or reason for this. For some people it works like a charm, for others it works after 15, 25 or 55 attempts, for some never.... This problem is widely discussed on several forums. Google it if you hit that roadblock.

To check if you are unlocked, boot the tablet and read the tiny script. It should say:

The device is unlocked."

Compatibility

Hi!

Great work on that rom! I see miscellaneous info about the compatibility of the tf300 roms with my me301t (asus memo pad smart). Is it takes some compatibility pack to make it work or it`s no go? I am using unofficial home brew omni 5.1 + twrp now.

Please note, in post #1 of this thread there is the install instructions given by Timduru: https://xdaforums.com/transformer-tf300t/development/rom-t3453702

Read the instructions very carefully and follow step by step without wandering away. Most important is to do firstly a clean installation after "Format Data" through Kang TWRP. After that flash Rom, Pico Gapps and SuperSU in one run.

Then wipe cash/Dalvik. Reboot! That's it! :cowboy:

hi! after 8 years i'm still using occasionally this pad (with katkiss updated)

but it's kind frustrating, it' very slow even using performance mode and locking the core at 1500mhz.

have you got the same experience? how do you use this pad for? youtube or netflix is a pain...
[Transformer TF300T Android Development] ebonit:
Very weird! I don't know anybody who complains about the performance of this rom (based on Android 7.1 Nougat), because it always runs like a charm.

I think after 8 years it's time to take care of that unique device with separate dock. Within post #1 of this thread you will find the "Install Instructions" by Timduru. Follow them step by step and do a clean install after format data through Kang TWRP. There is also a video about the rom. If you have any further question, you may aimed search this thread.
[Transformer TF300T Android Development] albyzaf:
thanks! i erased everything on the tablet and start back from 0, now it's much better! (not a world record in speed, but at least acceptable!)
[Transformer TF300T Android Development] ebonit:
Thanks for your report. Good job! But the result should be remarkable better than JB 4.2 (Stock Rom) after a clean installation!

Did you "Format Data" through Kang TWRP?

Please keep in mind Kang TWRP does a deeper format that rewrites everything in the partition. No moldy leftovers.

Did you change /data filesystem to f2fs?

(wipe => advanced wipe, check /data then "Repair or change filesystem" => change file system => and choose F2FS)

Finally go to (Settings -> Performance) and compare your settings:

Set clock values on boot

Set Governor on interaktiv

Minimum frequency: Current value: 204 MHz

Maximum frequency: Current value: 1500 MHz

Boot value: 1500 MHz

I/O scheduler current value: cfq

Set value on boot

Please don't forget that the memory of devise is limited. Therefore keep the amount of the apps as low as possible!

Guys do you know if browser2ram works with this rom?
[Transformer TF300T Android Development] vjuricic:
Slow system

I also have the same problem. Last year I made an installation of latest KatKiss (before new installation I cleaned everything...Dalvik, cache, system...).

But also I am having system that is sometimes slow to go nuts.

I think this is CPU/GPU problem as tablet is more than 8 years old.

It is probably time to buy new unless someone give me instruction hot to make it faster...and not downgrading system.
[Transformer TF300T Android Development] ebonit:
What does it mean?

Too many people mix up wipes and formats... Format Data is much more than wipe and means not factory reset, not wipe - you format data in ext4, then convert it to f2fs. Formatting data in Kang TWRP takes in general up to 1 hour +.

1. Did you "Format Data" through Kang TWRP?

Please keep in mind Kang TWRP does a deeper format that rewrites everything in the partition. No moldy leftovers.

2. Did you change /data filesystem to f2fs?

(wipe => advanced wipe, check /data then "Repair or change filesystem" => change file system => and choose F2FS)

If not, well just flash Kang TWRP recovery in fastboot (there is a download link within the install instructions by Timduru in post #1). Then use the recovery to format /data. Be patient and let it run!

Finally wipe cache and Dalvik. That will get you a squeaky clean system. Then flash the ROM of your choice.

BTW, tough this tablet tablet is 8 years old. But with Nougatella #39it is it on a acceptable Android level. The CPU is easy able to deal with it. But the most advantage is having a separate physical keybord as dock . So the device it's worth all efforts.

[Transformer TF300T Android Development] ebonit:
Keep in mind, you cannot do anything with a not perfekt working device. Also see that you get your tablet exactly working. Please note, any SD card must be in format FAT 32. That's very important!

When you mount the micro SD card in the tablet, you'll receive a notification that an SD card is mounted and I get an option to use it for transfer of files or as extension of the internal memory.

In case of the above mentioned notification you have to decide for transfer of files only. If you decide to extend the internal memory, you may throw away your SD card. You never can use it as an extern memory on the tablet again or re-format it for other use.

Conclusion: take a brand new card and format it on your PC as FAT 32. Then put it in your tablet and decide using it for file transfer, data and pictures and your issue will be solved. Don't forget to install a File Manager.

PS: When you ever want to thank for getting help, it is a good manner to use the thanks button. :cowboy:
