Thank you for the quick response, in your opinion, which is the best option for the upgrade. Which version of Android is the most suitable and have you tried to install Ubuntu?
[Asus  Eee Pad Transformer Prime] Raresh T:
If you go with gapps, marshmallow. If you go without gapps but hms (Huawei Mobile Services) , go with nougat. I did not try to install Ubuntu, since I am not a big fan of Linux distros.
[Asus  Eee Pad Transformer Prime] petttto:
Thank you again, can you give a link with steps on how to upgrade to Android Nougat.
[Asus  Eee Pad Transformer Prime] gaiex:
I sent an email to Asus asking for help to unlock my device and they reply that the unlocker app is only for ICS version.

Now I will reply that others used and it worked.

For what I could read online could be related to the SN on asus website not being correct because an RMA or something or even not registed.
[Asus  Eee Pad Transformer Prime] djmallinson:
will the mobile dock still work with 7.1 Nougat?

Hi Thanks for documenting all this. I just got the TF201 out of the closet and fired it up, I have the mobile dock will that still work? Is there anything needed to make the tab recognize the keyboard? thanks!

Hi,

Mostly use the Prime for watching movies these days but decided to play with it & install a custom ROM. I too am stuck at step 3, Unlock the bootloader: "An unknown error occurs which may be a network connection issue, please wait and try again later". Did you downgrade to ICS?

My tablet has never been RMA'd. I did upgrade from ICS to Jelly Bean shortly after receiving it. I just encrypted it thinking that maybe that if I was able to encrypt it perhaps it would knock something loose at ASUS & allow my unlock request to go thru, no luck.

Has anyone had success with this?

Thank you
[Asus  Eee Pad Transformer Prime] FigoCA:
Hi everybody,

does people having the network error with the unlock device app to unlock the bootloader have solved it?

I have the same error and despite several tries over several days it's always the same.

Thks
[Asus  Eee Pad Transformer Prime] Kalydor:
Hi,

i could not solve this issue. I think the unlocker is not working anymore. Maybe ASUS killed the service.

If you find any solution, please let me know.

Hi mate, Firstly thanks for this detailed guide. I've started to upgrade my dad's TF201 but i got an error message when i try to unlock my device.

"An unknown error occurs, which may be a network connection issue. please wait and try again later" this is the message. I tried to reset factory settings, removed google account but everytime i try i get this message. Is it possible to solve this problem or should i throw that old guy into trash? :)

Hello. I'm trying to install android 7.1 on the tf201 but I have a problem with twrp flashing.

Basically the touch screen of the tablet is broken and I cannot flash the hairybean recovery from twrp 2.6. I have the keyboard dongle with the mouse cable attached but the mouse doesn't seems to work. I read that from version 2.2 twrp has otg mouse support, but both the mouse from the keyboard and a usb mouse linked via the keyboard are not working. Will the otg cable connected directly to the tablet make any difference ?

I also read that I can use adb shell twrp without using the touch screen but it is available from twrp 2.8. and the last official twrp release for the tf201 is 2.6.3.0.

It seems that unofficial twrp version for the device have to be flashed from hairybean (i'd need twrp 2.8 or higher to use adb shell without having to use the touch screen).

Can someone help me out? thanks in advance.
[Asus  Eee Pad Transformer Prime] djibe89:
Hi @maisomenos , I'm not sure that flashing without full gesture support is wise. TWRP is a touch recovery.
[Asus  Eee Pad Transformer Prime] Beeble1983:
I'm stuck at this point. everything else backing up has worked fine.

I'm not 100% sure if 'APX mode' is just the screen RCK, ANDROID, USB, Wipe

Can anyone help?
[Asus  Eee Pad Transformer Prime] djibe89:
Hi, it is stated you must boot in APX mode, not bootloader (volume+, not volume-).

Screen IS black in APX mode. But you can check drivers are ok in Windows device management window
[Asus  Eee Pad Transformer Prime] Beeble1983:
It was the Driver, i uninstalled it in Device Manager and tied again - worked perfect!

I have KANG Twrp, and was able to install Kiss and SU.

But GApps pico 7.1 failed Error 64 - ***incompatible device detected***

I rebooted and tried to install GApps separately but same issue
[Asus  Eee Pad Transformer Prime] Beeble1983:
Sorry, it was another silly question. The file i have is ARM64, the installer was telling me to use the ARM version 🤦‍♂️
[Asus  Eee Pad Transformer Prime] Beeble1983:
Alright!!! I have been able to flash my TF201 after 10 years!

Thank you so much to @djibe89 for not only making this post, but for still being active on this Thread in 2021

I just want to add a few things because there is still a few out there who still need this upgrade but get stuck when trying to Unlock the BootLoader. I think it has been removed from ASUS. Go Here, (it is laid out for TF201) and will allow a work around.

The only other issue i had was when Installing, I received Error 64 - Device not compatible. It says...."use the version that is right for your device = ARM"

It took me longer than i want to admit that i was trying to install ARM64. Simple to download my own version of Open_GApp 7.1 ARM - pico. (From link in OP guide)

I love this forum!
[Asus  Eee Pad Transformer Prime] djibe89:
Hi @Beeble1983 , I'm glad you made it.

Still trying to save silicium with those tutorials.

Yes, my OpenGApps link is the good one :D

I added the link to tuto.

Enjoy
[Asus  Eee Pad Transformer Prime] Ice_83:
upgraded my TF201 using your instructions @djibe89, thanks a lot for your effort to summarise all this. All worked really well except the unlocking where i did have to follow the link you gave, experiment ask a few questions.

Not sure how long android 7 will stay ok but it definitively still ok now as i can e.g. watch movies on the tablet which didnt work on android 4.

@maisomenos , thanks a lot to you too!
[Asus  Eee Pad Transformer Prime] Stealth75:
@djibe89 I finally made it! Thanks to some extra help from many others here on this forum who I've already thanked.

I just have to ask though, I'm not sure if I missed something or did something wrong but my tablet is now slow AF!

I followed your tips for Kernel Adiutor and your other tips but I'm pretty sure my tablet is now actually slower than pre-rom.

Any ideas why?
[Asus  Eee Pad Transformer Prime] djibe89:
Hi @Stealth75 , glad you did it.

M sorry I can't be more precise about the unlock but I dont have the tab anymore.

For performances, look at the Root and Performances chapters of my tutorial, especially the Force GPU option.

Keep in touch
[Asus  Eee Pad Transformer Prime] Stealth75:
No worries, thanks anyway. I'll have another look. Knowing me I've missed something or done something the wrong way around. 🙃
[Asus  Eee Pad Transformer Prime] svarog_cs:

[Asus  Eee Pad Transformer Prime] jayrich131:
Hi, @djibe89

Thanks heaps for the tutorial man. I'm useless at computer stuff but you made the process doable and I managed to get it done. I am stuck on the setup step for the new version though. It just keeps saying Checking for Updates endlessly and if I go back and try to skip the step then the setup crashes. I saw a lot of questions in the thread about other bugs but didn't see any about this particular step being an issue. Do you have any ideas or memory of this step that might help me?

Thanks,

[Asus  Eee Pad Transformer Prime] rmcq:
Hi. After successfully unlocking my TF201 I’m trying to upgrade it to Android 7.1 following the procedure, but I’m stuck in step 6) Bootloader, more precisely after flashing HairyBean_Bootloader_TWRP2.5.zip to /sdcard.

Up to this point, I believe everything went perfect.

However, after choosing the “Reboot” option in TWRP, the tablet reboots normally to the ‘default’ Android 4.1.1 version, and never presents the “Do Not Install when SuperSU is proposed” option, nor does it open in HairyBean TWRP recovery.

Any suggestion on what might be the problem?

Thanks.
[Asus  Eee Pad Transformer Prime] djibe89:
Hi,

after pushing the bootloader, did you Install it ?
[Asus  Eee Pad Transformer Prime] rmcq:
Hi. I went to TWRP v2.6.3.0 -> Install -> Micro SDCard -> HairyBean_bootloader_TRRP2.5.zip and installed it.

The console indicated "Installing files.... Done..." and requested a reboot, which I did.

The tablet just reboots to TWRP v2.6.3.0 again, and trying to input the next command (fastboot -i 0x0b05 flash recovery twrp-3.2.3-0_KANG-tf201t.img) in the prompt only gives a < waiting for device > .
[Asus  Eee Pad Transformer Prime] djibe89:
In Windows's Device Management menu, do you see the tab ?
[Asus  Eee Pad Transformer Prime] rmcq:
I see an ASUS Android Device, but the controllers have a triangle with exclamation point in the symbol.

I've tried right-click install (without much success) and installing directly from the Device Manager > Action > Add Legacy Hardware and selecting the .inf files.
[Asus  Eee Pad Transformer Prime] djibe89:
You cannot flash while there is a yellow triangle.

Maybe tryfrom another PC ?
[Asus  Eee Pad Transformer Prime] rmcq:
Not sure how, but seems I managed to correctly install the drivers and got the KatKiss.zip and SuperSU.zip also installed.

The open_gapps-arm-7.1-pico*.zip is being more difficult - error 70 - but i see there are some fixes already provided in the forum and tomorrow will try it again.

Thanks for the help.
[Asus  Eee Pad Transformer Prime] djibe89:
Great.

Please tell me how you solved this GApps problem so I can improve the tutorial.

Tried Bitgapps instead ? https://www.androidfilehost.com/?fid=7161016148664807608
[Asus  Eee Pad Transformer Prime] rmcq:
Unfortunately I'm back at square 1 with this.

The problem installing GApps is error 70.

I've tried the link from step 8 of the procedure, and also tried a couple of other things, like adding a file of gapps-config.txt file, with the gapps exclusions, to the zip file.

Below is the size calculations log from trying to install GApps.
[Asus  Eee Pad Transformer Prime] djibe89:
Hi, did you wipe all partitions before flashing ?

You could try, flash Android only.

Install Android services https://m.apkpure.com/fr/google-pla...e0aab662cb479be7de57ce8?from=versions/version

And Play Store: https://m.apkpure.com/fr/google-play-store/com.android.vending
[Asus  Eee Pad Transformer Prime] rmcq:
Yes, I wiped all partitions as per the instructions.

Trying to flash Android only, but the tablets never boots to Android. It stays on the black screen with the ASUS logo for 30, 40 minutes.

Only think I can access is TWRP.
[Asus  Eee Pad Transformer Prime] djibe89:
Hi, wipe all partitions.

Flash Nougatella ROM.

Hello, I would like to improve and especially to be able to use a tablet which I acquired some time ago, but my os is obsolete, I have notions in windows but none in android, after some research I am joining you , a little tricky because I have to use google translate, because my level of English is poor (I am French).

Hello everyone here! I had a TF201, I have done the unlock section yesterday, and now I'm trying to find a good OS to flash, and I just wonder whether the Dock(Keyboard Dock) will work fine after i flash Android 7 or not?(like the whole keyboard includes those function keys, touchpad and USB ports)

another question, is Asus Keyboard(the original keyboard that comes with the pad) included in this OS?

Thanks!!

[Asus  Eee Pad Transformer Prime] Titiz BPR:
Hello community, I am coming back to you to share with you my disappointments concerning the upgrade of the tf201

and I greatly thank djibe89, for his sharing, methodology and pedagogy.

I followed his post on the tf201 to the letter, but I very quickly faced many problems.

A little summary of my environment.

I acquired a superb tablet asus tf201 very can use in a good non-rooted state with the latest updates: Android 4.1.1 (JellyBean;

Nvidia logo at the bottom right at startup)

bootloader V 10.4.2.18 , Kernel 3.1.10.00002-9599d0cf android@Mercury

I also switched it to developer mode with unlocking usb mode (debug usb) as well as allowing unknown original sources in security.

So far no worries.

I also backed up the data using backupyourmobile, even if I had no use for it, as a security measure

(but it only keeps the data sms, photo, ect ... no image disk, sorry I reason in os windows ....)

I had previously downloaded: djibe Transformer Prime pack v2, but it turned out to be obsolete,

djibe89 directed me to v3: https://www.androidfilehost.com/?fid=17825722713688260169 .

I installed the drivers using the command prompt mentioned in this post, which authorizes certificates other than windows,

but my computer under win10 64 bit forces the installation of drivers under windows, I also tried with a computer under win 10 32 bit

without success and under an xp sp3 ok but not found as a peripheral (not in the peripheral manager,

but in the desktop peripheral no tf201 or more precisely android ....)

Here I am, concerning this post, I then managed to root as previously mentioned with kingoroot and installed ESFileExplorer:

Now I can't install DMClient.apk and UnLock_App_V7, v6 yes but there is an error when launching it.
[Asus  Eee Pad Transformer Prime] Nektopoli:
Keyboard works fine, my keyboard eventually died do to old age (some keys stopped working). Good luck
[Asus  Eee Pad Transformer Prime] ryan940618:
Yea, I've done the flashing a few days ago, and the tablet works fine, its a bit laggy but I think its becuz of the old hardware, the rom is actually good, I'll put some screenshots if someone wants to see the difference between default rom and the new one.

(I use Nova Launcher in the new one instead of the launcher that comes with the rom, and the wallpaper isn't included in the rom, DM or quote me if someone need it. I also replaced the gallery app.)

Hello, I am brand new to this forum and I joined to see if I could find a way to salvage my Asus TF201 tablet. It locked up as I was only using it for a live photo display using Fotoo and Google Photos. I tried to soft reset it and now cannot get it to do anything. I've tried Volume Down and power and get to a menu with RCK, Android, a USB symbol and Wipe but none of those work. RCK does nothing but reboot where I see ASUS logo and just a circle at bottm that spins. Andorid reboots and shows me an android symbol on its back with exclamation point, USB does nothing and when I connect to my W10 laptop Explorer doesn't show tablet at all. Wipe reset does nothing but end up at Asus logo and spinning circle. All I want to do is get it back to where I can use it as photo display. Can I boot somehow from Micro SD card or somehow via USB when connected to laptop. I hate to throw it away but it is dead right now. Any suggestions would be much apprecitaed. BTW I don't know what firmware is on there (WW, US, etc.) I bought in US and tablet is stock. I have S/N near bottom plug but can't find how to use that info to find what firmware version I have.

Thanks for any help

Hi, my tablet with had a sudden death like this (with Android 7.1). Seems my partitions vanished. I suspect internal memory to be faulty
[Asus  Eee Pad Transformer Prime] ocalamike:
Thanks for reply. I have tried everything to get it to show anything other than Asus logo (Inspiring Innovation-Persistent Perfection) with 8 dot spinning circle below it and nothing has worked. It doesn't show anything when plugged into my laptop via USB. Maybe you are correct that internal memory died. Guess I'll just trash it and see if I can find a used Tf201 on Ebay for my photo frame. I have made a nice stand with a hole at bottom center so I can keep tabled plugged into AC power all the time rather than having to recharge. I don't plan on using it for anything other than photo slideshow of family pics. Thanks for responding.

Hi All,

Nice to see there is still some activity happening here. I have this ROM on a tf201 which is used as kids tablet. Although there have been various mentions on severe lag and suggestions on improving, nothing really seems to make the tablet run well enough for actual use.

Recently, I wiped it and followed the procedure and all recommendations (f2fs, media scanner, smartpack, etc.) from the initial post. After this, the tablet worked really well showing no significant lag! However, after some time the tablet became again really slow and laggy. Even navigating the Android menus is painful. This makes me think the problem has something to do with disk I/O. I cleared cache in recovery, but no real change.

Main question: is anyone of you using this tablet/ROM at a consistant acceptable speed? If so, any idea on what setting did the trick?

Thanks!

Hi All,

I have what seems to be a perfectly fine TF201. But it wont even load up the play store and the stock browser can load youtube.

I have tried following the detailed instructions to upgrade out of 4.1 but I cant get past step 3:unlocking the bootloader. The error message I get is :

"an unknown error occurs, which may be a network connection issue. please wait and try again later"

I have tried with and without a google account logged in with the same result. I have also tried 3 different networks with no change.

I tried the alternate method described in the link but then KingoRoot wouldn't load either. I thought that the version in the link (v7) was different to the one listed (v4.4.3). But not even older versions I tried would load and I couldn't find v4.4.3 anyway.

Can anyone suggest a way to proceed please?

[Asus  Eee Pad Transformer Prime] ryan940618:
So your purpose is to flash the rom, have you unlocked the device?

And also, since the device is published about 10 years ago, even if you upgrade it to Android 7.0, it's barely usable, like may not even able for you to smoothly play Youtube video.

But if you still wants to take a try, I'll try to assist :)
