Does anyone know if this ROM will work on Asus Memo tf301?

A friend if mine tried but it just goes into a boot loop but he thought tf300 Roms were compatible.

Does anyone know if this ROM will work on Asus me301t?
[Transformer TF300T Android Development] Okiera29:
it will not work on the ME301t just bootloops on the asus logo. I am trying to figure this android stuff out and see if I can make a compatibility pack like what has been done in the past.
[Transformer TF300T Android Development] bmonster:
Awesome kill app is back with v9, I've been waiting for that before I could upgrade.

Also how you getting on with bookmarks, has there been any progress.

Thanks for all your hard work..
[Transformer TF300T Android Development] scruffy1:
my only advice is don't update the bootloader - the "later" versions than that suggested ruin the install quite markedly - slow slow slow
[Transformer TF300T Android Development] suquet.paul:
My device was running KatKiss-5.1.1_026 (and it was running fine) and had an old version of TWRP (2.8.5.1@AREA51). I successfully updated TWRP to 2.8.7.2, but no matter what I wipe or how I wipe it, the thing doesn't boot. The tablet goes into bootloop. Turns off, turns on, asus logo shows up on screen, asus logo disappears after about 2 seconds, vibrating motor stays on for a solid 10 seconds, screen flickers, turns off, turns on and the cycle starts again.

I've tried redownloading and pushing the OS zip over again (just in case it was corrupt or something). I've tried not installing SuperSU or Gapps. I get the same results.

Any ideas?
[Transformer TF300T Android Development] scruffy1:
you need twrp_tf300t_kang_2.8.7.2

other versions are not going to make it work for you
[Transformer TF300T Android Development] MiniBlu:
If it vibrates it isn't a tf300t and is not compatible with this rom version. See below quote from tim made earlier in this thread.
[Transformer TF300T Android Development] suquet.paul:
Yeah, I just did a quick search on that symptom. And now I feel like an idiot. I checked the model name on the OS I had before and it said TF300. But after reading that post I ran to look at the box the tablet came in and indeed it ain't a 300. It's the 201. So duh. I'll move to that thread.

Thanks anyways guys!

Update: Booted up immediately. Conclusion: I'm an idiot. Cheers!

Hi.

I haven't used my TF300T in over a year as my charger broke and I never got round to buying a new one until just now.

I have fired it up and whilst the apps have all updated, I have received no system updates. Is this normal? I would have expected that there would have been multiple updates during the period that I have not been using it.
[Transformer TF300T Android Development] ebonit:
Yes, it is. :cowboy:

PS: You came up in this thread, so I suppose your tablet is on this Rom. To be up to date you must update it on version #32 manually by following the install instruction in post #1.
[Transformer TF300T Android Development] BrudnyPedro:
I am using latest 7.1 Nugatella. I have flashed it from stock rom using tutorial available on the forum. It runs very poor. A lot of slowdowns, freezes, even though I have followed every tutorial on optimization on this forum and I'm 100% sure Ive done everything correct. I've read that verion 4.2.2 is much better so naturaly I would like to try it. The problem is it is impossible. Im using TWRP 3.2.1, flashing ends without errors but the tab wont start. It stays in bootloop all the time. There is no problem with flashing Android 6.0 KatshMallow. I have tried version 5.1, also without success.

So, could someone help me?

Is it possible to flash from Android 7.1 to 4.2.2 using TWRP?

Any help will be appreciated.
[Transformer TF300T Android Development] MiniBlu:
If you are using twrp 3.2.1 you have not done everything 100% correct and have not followed the instructions in the OP. Correct twrp is required to get f2fs and it's benefits working correctly.
[Transformer TF300T Android Development] BrudnyPedro:
There was no problem at all with formating partitions to f2fs on TWRP 3.2.1 so whats the difference? Someone on the board also confirmed that you can use this version successfully.

So in your opinion I can't go back to old android version because I'm using wrong TWRP version?
[Transformer TF300T Android Development] Glomgold:
So it's been over a year since I made my first custom rom install and I couldn't have done it without this forum and the users! I was thinking about installing the lastest version, haven't done anything since everything has been working fine. I guess the new version includes some security fixes etc., is there any reason I shouldn't upgrade?
[Transformer TF300T Android Development] ebonit:
Yes, there is! The changelog of version #32 is "Port August 8.1 Oreo Security Fixes". That means this version has now the latest android 8.1 security patch. That's really a reason for an upgrade. Isn't it?

PS:

Please don't forget Tim to thank for his kindly efforts to keep our device always up to date! :cowboy:
[Transformer TF300T Android Development] elsmandino:
Thank you - all updated and working perfectly.
[Transformer TF300T Android Development] zurny:
W00t thanks for the update Tim!
[Transformer TF300T Android Development] Glomgold:
Problem! Never mess with a working thing.

So I updated to the latest version, did a wipe first, everything seemed fine the tablet booted and everything was working. I powered off the tablet and went on with my day, when I turned it on again it's in a boot loop. I get the ASUS-logo, it tries to boot and it returns to the ASUS-logo. I tried to do a factory reset in recovery but it doesn't complete, after around 30 seconds it jumps automatically to the ASUS-logo and tries to boot again!?
[Transformer TF300T Android Development] Glomgold:
So I did /format data and reflashed, everything went fine, no errors. All seemed to be working but when I turn the tablet on and off it takes several boot loops before it gets into the OS. There has to be some kind of compatibility issue? My tablet have a sim-card.

And now it's back to not booting at all.

Can't access recovery, stuck at Teamwin-logo, goes back to boot loop after a while.
[Transformer TF300T Android Development] bonzoe:
TF300T does not have a SIM slot so you have flashed the wrong ROM. You have TF300TG or TL?
[Transformer TF300T Android Development] Glomgold:
I've used this rom for over a year already, just flashed the new update, it's been established before that it works with the TG-model.
[Transformer TF300T Android Development] Glomgold:
Okey, after a lot of time and frustration I'm back on KatKiss 028, if this version also fails do anyone know where I can get the older version I had that was working? I believe it was 025.
[Transformer TF300T Android Development] rlezer:
you might not believe this , but i got mine still "stock"..

Is there an install guide that takes me to the process step by step , and what version do you advise : katkiss #032 ?

so i don't have any bootloader installed at the moment.

love to try this out, and give my asus tf300t a second life !
[Transformer TF300T Android Development] Babbsack:
Hi, of cause katkiss 032 is the one...

For a guide to the necesssary steps use the search function of this thread. Type in "guide" and you will find some hints. It is always recomended to read a bit first to understand what you need to do and to be sure.

Good luck and have fun!
[Transformer TF300T Android Development] rlezer:
thank you for the quick reply, and i hope to be a happy user of the new android rom soon ! :)

the current one is really old, and the tablet feels sluggy en slow.

i remember when i bought it , it was lightning fast ;)

Will keyboard dock work after this installation?
[Transformer TF300T Android Development] RudeboyXL:
Yes, works perfectly.

---------- Post added at 11:31 AM ---------- Previous post was at 11:23 AM ----------

For anyone who tested Katkiss Marshmallow and went back to Katkiss KitKat for stability and reliability reasons like myself, Katkiss Nougat truly is as stable as katkiss Kitkat. I had gone back to 4.4.4 for about a year after testing the Marshmallow ROM. I can say that the Marshmallow ROM put me off any more upgrades for the TF300T, but due to missing security updates and the need for higher android versions these days in order to support things like SMBv2, I decided to take the plunge and test the Nougat ROM. Basically it runs perfectly. Battery drain is ever so slightly higher but not enough to worry about. still get around a week of screen off/standby time.

Great work with the Nougat ROM [MENTION=3951330]timduru[/MENTION]
[Transformer TF300T Android Development] riban:
Developer mode doesn't seem to be available. Is there a reason for this? I want to get USB audio working.
[Transformer TF300T Android Development] RudeboyXL:
Developer mode works for me.

Settings>About> tap build number around 8 times, and back to main settings "developer mode" appears as expected.
[Transformer TF300T Android Development] riban:
Thanks - that was not working but since I updated to latest release it now does. (I reported it before updating because I didn't see anything in subsequent release notes about fixing this.) Anyway - it works now.
[Transformer TF300T Android Development] Scottvs:
I am having problems all of a sudden with this version of katkiss in my tf300t crashing after only being booted for a couple of minutes. It will crash and reboot without me even opening any apps. Any ideas why this could be happening?

[Transformer TF300T Android Development] gc2712:
Bluetooth audio stutter/pausing

When streaming radio over BT to my Bose bluetooth speaker there is a click or pause/stutter every few seconds. I don't recall this on earlier versions [now #32]. I have cleared BT cache and data, rebooted and still it persists. WiFi and internet bandwidth are both fine and not the issue [tested on the TF300] and the problem only occurs over Bluetooth. No other device in my house exhibits this issue with the Bose speaker and I think my TF700 on #31 does not do this when streaming radio to the same device.

Is this a known issue on the TF300, or perhaps is it just my device?

Can anyone suggest a workaround that would resolve this pause/stutter?
[Transformer TF300T Android Development] Scottvs:
Indeed, I did follow the instructions exactly as posted.

I did follow the instructions. It ran fine for probably a couple of months, but then all of a sudden I started having the continuous reboot happening. It keeps rebooting even when I have it closed, with the attached keyboard, and runs the battery completely down.

I'm not sure if it is worth trying to rebuild all over again, or finally decide it is time to give up the TF300T as too old and needs replacement.
[Transformer TF300T Android Development] ebonit:
Please try and calm down. This fine tablet combined with a dock is every effort worth to be kept alive. :cowboy:

First of all charge your device to 100%. After that try to get into Fastboot Protocol by holding the button power and volume down together. Three icons will appear. The first one, RCK, is blinking. Press volume up and your TWRP should start. Hopefully you have Kang TWRP. If so install Rom, Gapps and SuperSU again. Don't forget to do "Format Data" through Kang TWRP as first of all. It takes up to one hour. Be patient and let it run.
[Transformer TF300T Android Development] droozilla:
I had this start happening, tried everything from scans to reinstalls. Ended up being that the SD Storage on-board was dying. Got a replacement motherboard (they're not that expensive), everything works now.

BTW, the newest TWRP 3.2.3 works just fine. We can stop pushing the KANG.
[Transformer TF300T Android Development] gc2712:
Can you provide a link to the TWRP 3.2.3 version you mention that works? Did you format /data with F2FS using this version? [That's what failed for me in the past without using the KANG version mentioned in the first post.]
[Transformer TF300T Android Development] ebonit:
Here is the link to TeamWin: https://twrp.me/asus/asusTF300T.html

Please note, it's finally up to you to decide between Kang TWRP Recovery and TWRP 3.2.3. But it is to mention that Kang TWRP was made by Josh especially for Tim's TF300T custom rom. At that time TWRP wasn't able to change file system to F2FS. Now it is as well.

However as long as Tim advises in the install instructions in post #1 Kang TWRP Recovery for his custom rom there is no reason to take another recovery. So you may avoid any possible issues from the beginning.

What browser do you guys use?

I saw an old mention to "Lightning Web Browser" by Anthony Restaino, but the last update was July 2017, so I guess it is discontinued.
[Transformer TF300T Android Development] Mario3D13:
Hey guys!

So today my dad's TF300T running Nougatella 31 suddenly turned itself on and went into a bootloop. I can access fastboot and, if I reflash Kang TWRP, I can access recovery as well. However, when inside TWRP, it's unable to mount any of the internal system partitions (/system, /data, /cache, /misc, /boot) and ergo I can't format or flash to any of those. And beyond that, if I reboot the tablet, I can't go back into recovery from fastboot without reflashing.

Any suggestions on how to fix this would be greatly appreciated.

[Transformer TF300T Android Development] Kev_cr:
I had no problems flashing #033, my tf has been out of service for about 1 year and now it runs just fine... maybe a little bit slow but it's the first boot... anyway, what I came to say is:

Doing a clean install, configuration manager will keep force closing in widescreen mode, so the only way to get it to work is using the screen in vertical position... so far is the only thing that gave me some headaches lol

Thanks and congratulations for the work you've done!

TF300T dock problem

Yesterday I installed latest version of this ROM #33. Till than my dock was working without problem. Now it is only recognized as battery, but it is not recognized as keyboard. Trackpad is working but I can't get it to type anything.:confused:

If you have some idea or had similar problem please help me how to solve this issue.:good:

Thank you for any advice.
[Transformer TF300T Android Development] ebonit:
First of all your issue isn't caused by #33. It seems there might be something went wrong during the upgrade process. Did you follow the install instructions in post #1 carefully, didn't you?

To solve the issue do a clean flash as advised in the install instructions. Make sure that you at first format/data through Kang TWRP. It may take up to one hour. Be patient and let it run.
[Transformer TF300T Android Development] vjuricic:
I did as instructions said.I used Kang Twrp, format and all as instructed. I will try to repeat all again and hope all will work.

If that does not work than it is probably some hardware issue with keyboard. As I read flex cable can cause an issue.

Thanks for advise. I will inform how it goes.

I'm very satisfied with Lightning Browser!

Lightning Browser is a simple, very fast web browser that focuses on design, security, and efficiency. It doesn't track you. Gives you a lot of options to protect your privacy.

BTW, I never had any issue like known with Google Chrome and others. :cowboy:
[Transformer TF300T Android Development] gc2712:
I just tried Opera suggested in the post above and opened the same sites in both Lightning and Opera. Opera clearly faster. I'm also a bit concerned that Lightning is never updated with each new ROM version. It's getting a bit old now.
[Transformer TF300T Android Development] ebonit:
Good job, thanks! It's good to report about comparing both browser here in the forum.

The result about the speed speaks finally for Opera. Up to now the greatest advantage of lightning was it doesn't track like the most of the other browser stuff. However Opera also doesn't track. There is a "do not track feature" included witch always can be enabled if needed. :good:

PS:

If you prefer to opt-out Opera of online behavioral tracking, you can set the option “Ask websites not to track me” in Settings > Preferences > Advanced > Security .

Can I lower microphone volume?

When making voice calls on my TF300 (Skype or Hangouts), recipients complain that my voice is too loud and distorted. The "input record" slider in K.A.T audio app doesn't seem to reduce mic sensitivity or alter anything in my tests. Playback speaker volume is adjustable and very satisfactory for my use.

the prior gapps (open_gapps-arm-7.1-pico-20180512) that worked on 029 also threw the same error

edit : the 29 version reinstalled fine

i'm downloading the mirrored version of #33 in case the first one was corrupt
[Transformer TF300T Android Development] ebonit:
Please note, there is a well-known rule. If you want to change anything like the Gapps you should download ROM, Gapps and SuperSU in post #1 again and install them in one run.

Are there any issues before you should do a clean install. That means format data through Kang TWRP.

Good luck!

SD Card Internal Storage Bug

Timduru, I had some problems trying to format my SD card to work as an internal storage for my device after I installed the last build of your system (KatKiss-7.1_TF300T_034). In the previous build it was working normally, but now when I try to put my 32GB SD card and format it as internal system storage, the system gives me an error message that reads as follows: java.util.concurrent.TimeoutException: Thread Binder: 1649_E gave up waiting for partitionPrivate after 180000ms. What could it be?

Ps: I use your OS in my Asus Transformer Pad TF300TG, and the build I was using did not give me this bug, only in this last update that started to give this problem with my SD card. Remembering that I use a basic generic 32GB SD card.
