Help at step 4 with 'fastboot devices'.

I get to step 4 with 'fastboot' the cannot get past that point... Win10/64 & Win7/64 systems used to try getting it updated. Not sure what steps to take unless I get a Win7/32 system to try it on...
[Transformer TF300T General] Kreuger:
Hey guys. I got another device that already has CWM flashed on it. It currently has no OS. I'm trying to put twrp on the tablet before flashing katkiss. I tried using adb reboot fastboot but it just brings me back into the recovery.
[Transformer TF300T General] ebonit:
Please get your device back on a clean JB 4.2.2. After that follow up exactly the install instructions by [MENTION=3951330]timduru[/MENTION] https://xdaforums.com/transformer-tf300t/development/rom-t3453702

Here we go:

Download “Minimal ADB and Fastboot”. Make a folder C:/Fastboot and extract it there and install it. Download firmware WW_V10.6.1.27.5 from the ASUS official website and unzip it twice. Copy the .blob file from WW_V10.6.1.27.5 into the folder C:/Fastboot.

Open “Minimal ADB and Fastboot” and put in "fastboot devices". The device should appear as "xxx device".

Now type in step by step (wait after every step!):

fastboot erase system

fastboot erase recovery

Fastboot erase user data

fastboot erase boot

fastboot erase misc

fastboot erase cache

After that open C:\Flash and put in "fastboot -i 0x0B05 flash system blob" without " " .

Now it takes a while "sending..." appears then "write..." and the load status will be shown.

If loading is finished put in "fastboot -i 0x0B05 reboot". It takes a while to start into a clean JB 4.2.2!
[Transformer TF300T General] Kreuger:
It turns out that I had wiped the data partition. I fixed this with the step of changing the filesystem type f2fs. Now I am able to resume flashing the rom. I was able to do everything else without failure but it just hangs on the asus screen where it says "the device is unlocked" and yes, I waited more than 10 mins. In fact after 2 hours, it had gotten nowhere. I tried wiping everything and flashing again but am currently stuck in the same spot.
[Transformer TF300T General] ghep:
stuck

Do you mean copy the zip files or extract their contents to the SD card?

I couldn't unlock the device and I couldn't copy the unlock file to root reason being:- 'permission denied'

so I followed this instruction:-

### If it fails to install, delete your Google Account. Go to Settings -> Accounts. Delete the Google Account.

subsequently my Wi-Fi indicator is fixed on grey and I can't get my google accounts back

I can still browse the internet but I can't use Play Store to download SuperSU which apparently doesn't allow you change the permissions but just view them.

I am using a Virtual Windows 7 in Linux although my Linux sees the tablet immediately in an mtp window.

Any suggestions on my next step?
[Transformer TF300T General] ebonit:
Download firmware WW_V10.6.1.27.5 from the ASUS official website and unzip it twice. Copy the .blob file from WW_V10.6.1.27.5 into the folder C:/Fastboot.
[Transformer TF300T General] ghep:
I managed to get my google account back by enabling Chrome and logging in from it and my account reappeared on the tablet.

however I am still unable to Unlock it.
[Transformer TF300T General] ebonit:
Please check if the bootloader oft your device ends with 27.1 vor 27.5. If not, upgrade your device on Android 4.2 Jelly Bean.
[Transformer TF300T General] ghep:
Thanks for reply

I'm on 27.5

I'm doing this on Linux and can access the tablet with fastboot but not adb.

Oops, I've got 2 tf300t tablets and one is stuck in a bootloop (ASUS logo and circling circle)

So I'm trying to learn how to use adb and fastboot on the broken one before I start on one the working one.

Strangely the working one can be seen from adb but not fastboot and the broken one is seen from fastboot but not adb (devices command)

So reading up on fastboot commands to see what I can do.
[Transformer TF300T General] ghep:
I finally managed to do it, the key to it was resetting the tablet to factory settings and skipping the Google sign ins. As soon as I did this I was able to unlock it and do everything as instructed.

The only glitch was the

"[+ OpenGapps ARM 7.1 Pico (Pico Pico Pico only !) : https://opengapps.org/?api=7.1&variant=pico]"

link which pointed to the wrong download I'm still not sure if I got the right one anyway.

Now I'm having to work out how this new Tablet works it's another world.

One thing I haven't been able to find is how to take a screenshot. Any ideas?

Thanks to everyone for the help.
[Transformer TF300T General] djibe89:
Hi, glad you like it.

Thanks to you I fixed OpenGapps download link for ARM 7.1 pico build : https://opengapps.org/?arch=arm&api=7.1&variant=pico

Enjoy
[Transformer TF300T General] ghep:
No all thanks go to you I,m in awe of what you,ve done. I checked out the link on page 1 of the tutorial and then the same link on page 25 and they are different. Sorry about that, I feel bad about pointing it out.

From my experience you can,t copy the Asus unlock file to the Internal partition until you,ve rooted it and you can,t root it until you,ve done a factory reset then skipping the Google logins during the following initial set up. Then you can unlock it and start the upgrade process.

I must say that unrooting the tablet must be like the feeling a prisoner gets when he is released from jail. Freedom.!

Freedom to do what you want copy, move, delete and create files and directories where you want.

Hi,

I have wiped out and installed the O/S succesfully. However once tab boots I see only KAT browser. I dont see play store. WHen I goto settings and accounts, I am unable to add my google account. NOt sure what I missed. Could you please help me to get play store and my google account configured so that I can install other apps . THanks.
[Transformer TF300T General] djibe89:
Hi, it looks like your OpenGapps were not installed.

Back to TWRP recovery > Install > Select Gapps > Flash

Wipe Cache/Dalvik > Reboot.

Tell me if it fixes it.
[Transformer TF300T General] manickaraja:
HI,

Yes. it did fix. Thank you so much. However I havent done "Wipe Cache/Dalvik". Will it degrade my tab performance? Since already I came out and rebooted could you please let me know how to remove the same now. Thanks.
[Transformer TF300T General] djibe89:
Remove files ?

Use File explorer app or connect to Windows to remove install files.

If you experience bugs you'll have to wipe cache/dalvik in recovery.
[Transformer TF300T General] manickaraja:
Please let me know the location for removing files through file explorer. Also if it fails navigation to remove it from recovery console. Thank you very much for your help again.

I'm stuck at the very first step: upgrading bootloader version to xxx27.5.

When booting under bootloader, thant RCK with the file EP201_768_SDUPDATE.zip in the sd card, error comes. No further logs.

What is the problem?

I already wiped the whole tablet (option wipe in bootloader). Same error. I set developer option (7 clicks on build), debug mode.

can anybody help?

is there a new thread in the meantime?

thanks a lot.

[Transformer TF300T General] gpanagiv:
I did downgrade! But this is not a good idea at all. According to a most recent post, TF300TG (WW_epad-10.6.2.11-20131213 A03) works well with this guide (it only loses the G feature of wifi).

By downgrading you could lose the bootloader version as i did! :( :( :(

And where can you find it again?

[Transformer TF300T General] djibe89:
Hi,

according to this thread https://xdaforums.com/oneplus-one/general/official-lineageos-15-1-t3805679/page9 you can try :

- Make sure in TWRP options that zip verification is NOT checked.

- Make sure your installer zipfile is single on your SD card, without any .md5 or .sha signature file.

Tell us what you get.

unable to boot after flashing rom and gapps

hello, thanks a lot for the tutorial. i did everything till step 6.

firstly, the gapps 7.1 pico didnt install. its said rom is for 5.1.1. so i tried with 5.1 pico and it worked,

secondly, after 6, on reboot, the screen is stuck on asus logo, the first one which is 2d. doesnt go beyond that. i could relate it to discussions on bootloop.

please tell
[Transformer TF300T General] djibe89:
Hello,

are you on Katkiss v39 ?

You can't install OpenGapps 5 on 7.1.

There must be a problem with the files you flashed.

Download : https://downloads.timduru.org/android/tf300t/K.A.T/KatKiss/7.x/dev/KatKiss-7.1_TF300T_039.zip + https://opengapps.org/?arch=arm&api=7.1&variant=pico

Go back to TWRP recovery.

Wipe all partitions.

Flash ROM then OpenGapps.

Tell us how it is.
[Transformer TF300T General] salcaesar:
ok thanks. will try this again.

do i not flash super su along this time or i can do that later once it works?

i actually tried few things.

i flashed asus 4.2.1 firmware from the official site using blob extracted twice. it did install but only took me to next 3d asus screen with revolving dot three times.

i tried installing using kang but with f2fs but no change.

infact kang initially said 'checking md5 file...not found' but installed it nevertheless. same happened for gapps. asking for 5.1 ver instead of 7.1.

also, can i boot with katkiss only and later install gapps?

meanwhile i will reinstall with the files you suggested and get back

thanks and regards

Hi,

I first would like to thank djibe89 and timduru for providing this tutorial and ROM! My Asus TF300T has never run so smooth as it does now! It is more usable now than it has ever been.

Although it is already very usable I have a small problem which is most likely due to a misunderstanding from my side. I did not get/have a setup procedure when the tab started for the first time after the ROM update (I assume there should be a setup procedure). I have the impression that due to the fact that I did not encounter this procedure that my tab is still not properly setup.

The reason I have this impression is that I cannot activate the developer mode. Also downloading of apps via Google Play does not work.

I have been seaching on the internet and installed nova launcher to be able to run the SetupWizardTestActivity . Problem is that I cannot find this widget, it seems itis not installed on the tab?

I also read about using abd shell but for that I need to put my tab into USB debugging which I cannot do due to not being able to activate the developer mode.

Is there anybody that can help me in fixing this problem?
[Transformer TF300T General] djibe89:
Hi, for a clean install,

you can go back to TWRP recovery.

Format completely Data partition,

Quick format cache, system partitions.

Then Install zips of ROM > addonsu > OpenGapps.

Wipe cache/dalvik > restart tab.
[Transformer TF300T General] djibe89:
Proceed in this order

1. What is TWRP version you are using ?

2. Hi, was your devce encrypted ?

Remove SIM card from phone.

3. Try a full format of Data partition And Quick format of cache + system partitions.

If first 3 fail, Go to Advanced wipe. Try to format /Data partition in F2FS. Then format back to EXT4.

Tell us about your success.
[Transformer TF300T General] noeft:
Hello Djibe89.

Your advise worked! The tab now works great. After installation and restart it now came with the setup process (which is previously didn't). I can now also enable developer mode and I am able to install apps via Google Play!

I installed the ZIPs one by one instead of selecting them all and do a one time installation. I don't know if this did the trick but I'm very happy with the result!

Hello, I keep getting network error when using the unlocking app and I tried everything suggested on this thread. Do you know what should i ask to asus support?
[Transformer TF300T General] djibe89:
Hi, can you try this to Unlock tab ?

The work-around is easy enough: 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

- Tried both Unlock tools ?

- Tried > 20 times each unlock tool ?
[Transformer TF300T General] gamervishal:
Thanks for the ROM. Worked like a charm with TWRP 3.3 and latest Magisk (instead of SU).

Few tips

I wasn't required to install any of the drivers. Everything ran fine on the fresh system.

Change USB port if fastboot fails to send file

TWRP needs a restart once installed to mount internal partitions

Optional: I installed Magisk instead of SU (since I find it much more interactive), this has to be done after ROM booting

Thanks again!
[Transformer TF300T General] Saetta_McQueen:
Help me please

Hello guys. First of all thanks for the guide.

I need help, please.

I followed the guide to step 6 without problems, but at this point:

“Custom ROM is installed and system is rooted.

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

Then Reboot System.

Let the tab start (at least 10 minutes)”.

When the tablet restarts, after a few second, it return in the “Team Win RecoveryProject” menu, instead of loading android.

Where am I wrong?

Edit: I'm a idiot... My error was let the tablet connected at the pc :rolleyes:

Sorry. Many thanks again.

Endless TWRP boot loop

Hi everybody,

I need you because I've done a mistake. My TF300T boot loop on twrp everytime.

I wanted to increase speed of my tablet and migrate from 4.4.4 to 7.1 with F2FS for /data.

Original setup already flashed

TF300T with KatKiss 4.4.4 of timduru already unlock

bootloader TF300T-WW_epad-10_6_1_27_5-UpdateLauncher

TWRP 2.8.7.2

I flashed with the timduru process: https://xdaforums.com/transformer-tf300t/development/rom-t3453702

TWRP 2.8.7.2

KatKiss-7.1_TF300T_039

UPDATE-SuperSU-v2.82-20170528234214

open_gapps-arm-7.1-pico-20191230

It was a success for the flash, the ROM boot with a lot of time but Android was very slow and stuck directly even after wifi connection: unusable. The last version of open_gapps from 20200530 didn't work, that's why I tried the older one with success.

At this step, I could go to bootloader with home + vol- and twrp without problem.

Then I found your other setup process with TWRP 3.3.1-0

I notice this sentence: "### But this 2.8 TWRP has huge problems with F2FS. So I prefer latest official one."

I follow everything, I flash recovery with TWRP 3.3.1-0 with fastboot: success

I follow the process and home + vol- go to twrp but it crash before reach the menu and reboot automatically to the very long katkiss start.

I saw the following warning but I selected the Wipe data icon to "normally I said to me" erase android and start again from twrp to reformat the data partition, setup katkiss...

"###### FROM NOW ON, ONLY USE TWRP RECOVERY TO WIPE DATA OR PARTITIONS, never again bootloader's Wipe data icon !!!"

Very bad idea!!! I'm completely a noob! After that, the tablet endless boot loop on twrp 3.3.1-0 but each time without access to the menu. It crash continuously.

It's my actual state.

But I can't access now to the bootloader with home + vol-! This is the worst!

My hope to have a more powerfull tablet disappear... :(

Do you have an idea to help me to solve this situation?
[Transformer TF300T General] djibe89:
Hi, what happens if you flash twrp again ?

fastboot -i 0x0b05 flash recovery twrp-3.3.1-0-tf300t.img

fastboot -i 0x0b05 reboot-bootloader

and confirm with Volume+ to get into RCK (recovery, again), it is now TWRP 3.3.1-0

If it doesn't work, you'll have to go there : https://xdaforums.com/showpost.php?p=44244313&postcount=12

Thank you for you reply.

The recovery with Home and volum - does not work. It's not displayed at all.

I have only directly the TWRP 3.3.1 automatically launched After Asus logo.

I see TWRP logo but It crash every time and reboot....

What do you mean with volum +? I don't know this switch.

I will try the recovery restore.

---------- Post added at 09:12 PM ---------- Previous post was at 08:19 PM ----------

The procedure from ozkrtech and then Buster works! Great!

It was necessary for me to execute "adb reboot-bootloader" during the TWRP boot to access to the RCK.

And then, fastboot was accessible and I follow the Buster process.

Thank you very much.

Now I'm with the stock version in 4.2.1 :)

The 7.1 is it really faster than the 4.2.1?
[Transformer TF300T General] djibe89:
Faster and compatible with every modern app.

Wifi issue

Hi everyone,

First I'd like to thanks timdu, djibe and all involved in, what I could call, a true revival. :good:

Everything went fine but I have a little problem. Wifi interface is ok BUT I can't connect to my router. On android JB official rom, there was no problem. With this Nougat rom I can detect networks I didn't suspect (maybe far neighbours) but not my own :(

Does anybody got an idea ?
[Transformer TF300T General] ebonit:
Firstly to your understanding. If the device can detect neighbor networks, everything is fine. So you have to prepare your WiFi channel on your own router. Sometimes the Rom doesn't recognize Channel 12 an 13. Please avoid them and change your router setting to any other channel.

Please report the result! :cowboy:
[Transformer TF300T General] barbe31:
Yep I knew that was something not so serious. Finally I restarted my router for another reason and I suppose it changed the channel. Anyway, it's working flawlessly. Thanks again et thank you ebonite for helping people in need in tf300t forums.

Hi. Thx for your help [MENTION=7106193]ebonit[/MENTION]

I updated tutorial to state those fixes.
[Transformer TF300T General] dark_days:
i have resetted the tablet now for the 20th time, it still does not work. When did you manage to rest it? just recently or some time ago?
[Transformer TF300T General] ebonit:
Your problem is well known and widely discussed on several forums. To your understanding please Google it firstly if you want to unlock your devise. Here we go:

1. V8 does not install at all anymore. So keep your hands off. V7 will install if you allow "less secure apps" in your Google account settings. On the web - not your Google account on the tablet!

2. Delete the Google account from the tablet (Settings > Accounts), then run the tool again,

3. 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....

To check finally if you are unlocked, boot the tablet and read the tiny script in the left corner above. It should say: “The device is unlocked”.
[Transformer TF300T General] Freekers1337:
I think the issue is that the Unlock Device Tool is trying to query a domain that does no longer repond. It is trying to send a query to: mdmnotify1.asus.com but that has no DNS record associated with it anymore.

I tried looking up the DNS history to check if I could find out which IP belonged to this DNS entry, but all IPs listed here do no longer respond: https://otx.alienvault.com/indicator/hostname/mdmnotify1.asus.com
[Transformer TF300T General] dark_days:
Well this would match to that what the german asus Service guy told me.

I wonder if others ate having the same Problem now..

I really would have Updated the device...
