You have all the instructions in the 1st post. I have a little troubles but following the instructions i have done!! Do a format data. Is the first step.

[Transformer TF300T Android Development] yannmrt:
Thanks, like stipulated before I already did the format and convert the data folder, few times now, and follow all instructions but still get stop at the logo.

I really don't see where I make or can make mistakes. I check all MD5 as well.

Any other idea?
[Transformer TF300T Android Development] ebonit:
As you may remember you made several changes in the past. Believe it or not, it seems something went wrong. So your device isn't clean at all. Before you do anything else that can brick your device totally I would recommend to get back on Stock Rom JB 4.2. After that you will have a clean system. You must flash Kang TWRP 2.8.7.2 again and after that any rom of your choice.

Please look at following thread and follow post #2: https://xdaforums.com/transformer-tf300t/help/softbricked-tf300t-trying-to-flash-to-t3508565
[Transformer TF300T Android Development] yannmrt:
After many try, following your post step by step, installing KANG TWRP 2.8.7.2 and following the post to install katkiss I always come back to the same problem. I'm really desperate :(
[Transformer TF300T Android Development] ebonit:
I'm sorry, but your report is too poor in order to make an appraisal. There are three questions left you may answer on:

1. After getting back on Stock Rom did your tablet boot well and all apps like WiFi did work well?,

2. What time tooks the

full wipe

before installing the custom rom ? (it must be slightest take one hour +),

3. Did you flash Rom, SuperSU and Gapps in one run before wipe Cache/Dalvik and reboot?
[Transformer TF300T Android Development] yannmrt:
Hello Ebonit

Sorry to don't give all info you need.

1 the boot went well and I only try the Wi-Fi and yes it was working. Should I try some things else let me know if never I will reinstall everything I will know.

2 yes format data take long time, I can't tell you if it was more or else one hour I didn't check it. But for sure it take much. More time than before. I take it as a good sign.

3 Yes I install Rom, supersu, gapps before to wipe as per instructions on the installation post.

Let me know if you need more info. I can redo everything and look at specific points if you let me know.

Thanks for your time.
[Transformer TF300T Android Development] ebonit:
Thanks for your reply. You are killing me!

Last question: did you take the right Gapps "pico" ?

If yes, please read this thread carefully https://xdaforums.com/transformer-tf300t/help/tf300t-stable-boot-t3511097/page2. Maybe you can figure out if you failed somewhere and why. Hope so. Don't hope your case is the same like there.
[Transformer TF300T Android Development] yannmrt:
Yep very similar problems. My gapps is Pico. But any way the problem doesn't since to come from supersu or gapps because I try to I stall katkiss without those, and problems is the same.

I will try again and as well try to don't covert to f2fs.

Could you tell me how to do to have TWRP to check the MD5 I check my self on the pic but would like to have it check by TWRP.

Thanks and stay tuned :silly:
[Transformer TF300T Android Development] compact_wisdom:
Put a text file with the md5 into the same folder on your device as the rom, give the same file name but ending with .md5.

Please be aware that the time format /data takes varies with the size of your built in flash storage, obviously.
[Transformer TF300T Android Development] ChiTownPack:
Thank you, Timduru for keeping this device alive with your great ROMs! You are truly amazing!

I wanted to ask if anyone has had any luck encrypting their tf300t with the new nugatella ROM?

I am trying to encrypt but it keeps rebooting.

I updated from Kashmellow #029 to Nougatella #014 using the following steps:

1. Full wipe (data, system, dalvik, cache & internal storage) and format /data to ext4

2. Convert /data to F2FS

3. Install katkiss nugatella #014

4. Install SuperSU

5. Install open gapps

6. Wipe cache & Dalvik

7. reboot

Then when I try to encrypt it, I get the first screen explaining how long encryption takes. I click on the "ENCRYPT TABLET" button.

I enter my pin

then I get the "encryption is irreversible" screen. I click "ENCRYPT TABLET"

It then goes to the black screen with the green encryption android guy for one second and reboots.

It is not encrypting.

I switched from the kang 2.8.7.2 recovery to the twrp 3.0.2-0 recovery and it still does the same thing.

Here are all of the versions of software I am using.

bootloader: Android cardhu-user bootloader <1.00 e> released by "US_epad-10.6.1.27.5-20130902" A03

recovery: twrp 3.0.2-0 (was on recovery kang 2.8.7.2)

Supersu: v2.79-20161211114519

katkiss nugatella #014

open gapps-arm-7.1-nano-20161230

K.A.T App: K.A.T_v2.4.2.apk

Not sure if it is a kernel setting or something that is causing the reboot? I've tried it multiple times with the same result.

Any help is appreciated.

Can I install the needed recovery version through other twrp version? Unfortunately my volume up button it's not working.
[Transformer TF300T Android Development] ebonit:
First of all it seems you did a good job. I cannot figure out why the process failed. I would like to recommend to run the install process again. Maybe someone else has a better idea. Take care of the full wipe. It must take one hour plus.

BTW, unlock is irreversible. If done, it's for ever!

---------- Post added at 05:34 PM ---------- Previous post was at 05:07 PM ----------

Yes you can! No data won't get lost. What TWRP version do you have? Newer one are able to flash both *.zip files and *.img files.
[Transformer TF300T Android Development] yannmrt:
If format data does not take one hour this can be a part to the problem.

Do other TWRP those about the same job than KANG TWRP? What it is so special compared to other one?

Because I would like to try to install other one and see what happens, any way I can use the tablet so I can try lot of think. If it's broken at leat I will have a good excuse to change it. :silly:
[Transformer TF300T Android Development] ebonit:
The only advise I could get you is stay away from changing Kang TWRP. To use Kang TWRP before installing one of his custom rom is advised by the developer Timduru. So you may take it or leave it. It's up to you.

However it would be better to take care of a full wipe: Wipe=>Format Data=>keyboard opens=>Type "YES" to continue=>wait patiently until the Wipe is done. This is more than a Factory Reset. It cleans your system totally.

during first start, after language choice, choose "set up as new", set up wifi and

I'll try this.

1. Click detect and press Space.

2. Activate CTRLL (change color to green)

3. Add keycode 204

Result:

current combination - WIRELESS +Ctrll ==> Send Key: LANGUAGE_SWITCH

:confused:
[Transformer TF300T Android Development] timduru:
you most likely hit the wrong +

also I've added the switch input language action a long time ago, so you can simply choose it from the list instead of doing a send keycode
[Transformer TF300T Android Development] BrateloSlava:
Yes, wrong +. :D

Russian interface doesn't contain "Switch Languages" in available actions. Only worked - direct input key combinations.

I know that, the problem is that my volume up button it's not working and I need it to select RCK.

My twrp version it's 2.8.5.0. I can do it through adb easily. But will OMNI ROM be able to initialyze with the KANG TWRP? Remember that I don't have the volume up button working to force the boot to the recovery. So I need to get in the ROM and reboot to recovery and continue the instalation of the KANG ROM and other things.

I just don't want to be stuck in the bootloader because I don't have a way to surpass it.

Thanks in advance!

Not sure what to do to install nougat.

I'm a little slow on the uptake, so please speak slowly. I want to install nougat on my TF300. I have already installed MM 013 which works well. I didn't save any of the links to the instructions when I installed MM. The instructions say to use KANG TWRP recovery. I'm not sure which recovery I have installed. How do I tell? The link to the KANG in this forum leads to a thread that seems to only discuss problems and doesn't link a download site or install site.

I'm not sure if I have the right bootloader. When I open the bootloader, it reads (android cardhu-user bootloader <1.00 e> released by "us_epad-10.6.1.27.5-20130902" A03). Then it reads team win recovery project v2.8.01.

I would appreciate some help with this matter.

Thanks
[Transformer TF300T Android Development] ebonit:
Your TWRP version is fine. If you want to install OMNI ROM, I see no need to change anything.

Does either your volume down button work properly or pressing your power button opens a window that allows you also to start into recovery?
[Transformer TF300T Android Development] igoigo:
I'm not sure if I explained myself correctly. From the begining, I have the OMNI ROM installed in my TF300 with TWRP 2.8.5.0.

I want to change ROM to KatKiss nougatella. In order to do that I must install KANG TWRP. Since my vol up button it's not working I must boot the ROM and select the option to reboot to recovery.

I'm afraid that if I install the KANG TWRP the OMNI ROM won't be able to boot. As I said before I will need to manually choose the option reboot to recovery to install the remain files (nougatella, gapps and so on).

So my question is, are KANG TWRP recovery and OMNI compatible? With KANG TWRP will I be able to boot this rom normally?

Nice job! One thing that probably nobody has noticed so far as I am probably the only person in Iceland using this tablet/rom.

The icelandic keyboard layout for the external asusdec is matching except for the following key:

LEFT_BRACKET: Key 71 now gives the capital letter Đ, unicode U0110 and the small letter đ, unicode U0111 .

This key should actually give the letter capital letter Ð, unicode U00D0 and the small letter ð, unicode U00F0.

I know it´s hard to see the difference but it matters a lot in for example search engines. Is there any way to fix this? I can´t find the asusdec.kcm keyboard layout anymore (as could be found on the stock android from asus) , so there is probably another way the keyboard layouts for the additional languages are mounted... Any ideas?

Good evening to all,

I still looking at my problem to don't be able to install any rom other that original Asus (i just try to install OMNI as well with same unfortunate result). I would like to know when booting from bootloader to KANG TWRP I have kind of scramble line for few second before to get the pingouins, this is normal ?

Thanks

[Transformer TF300T Android Development] xxxericxxx:
Hey yannmrt, noticed when you posted the install process you had listed /cache as formatting in f2fs, if that is what is happening, that is probably the problem, the only thing that should be f2fs is /data. I could be wrong but see if that helps.
[Transformer TF300T Android Development] Pourrito:
Yes, please ! Do ! :p
[Transformer TF300T Android Development] yannmrt:
I don't really did it my self, TWRP did when I factory reset. Even when I wipe cache and dalvik at the end of installing all software and before rebooting it is happening the same. Not sure if it is normal or not.
[Transformer TF300T Android Development] ebonit:
It seems to be a never ending story. I went through your list again.

TWRP-> F2FS

TWRP Msg

Change Data to F2FS?

Swipe to change

Until here it looks fine, but why this step?:

Formating Data using mkfs.f2fs (take less than one minute)

Done

This might be my last note to this case.

Please lets start again: Open TWRP =>Wipe =>Format Data =>a window opens with a red note! and a key board appears =>type "yes" to continue. If done, let it run. It may take one hour +. Don't disturb the process!!!

When finished go back to the TWRP main screen =>Wipe =>Advanced Wipe =>check Data =>Repair or change File System =>Change File System =>F2FS

After that go back to the TWRP main screen push =>Install. Add ROM, Gapps and SuperSU and flash them in one run. Then =>Wipe =>Dalvik Cache =>Reboot. That should it be. Good luck! :cowboy:

You can always dirty flash subsequent releases of a rom, unless specifically instructed by the developer to do a full wipe.

Or unless you encounter strange problems after dirty flashing, then you should take a format /data into account.

Well, after 4+ years of owning and using my TF300T, I am finally going to say goodbye to it. I purchased a new Samsung Galaxy Note S2 9.7" (2016) tablet and I am truly blown away by it.

I know I will miss using the Asus tablet. But even more I will miss the community and support that exists here on XDA. There are many who contributed to the updates and awesome custom ROM's over the last four years but in particular many thanks and much appreciation to sbdags and timduru. They have kept life in this fantastic piece of technology over the years. The support and help from the community at large is second to none. In the same time period my wife and I have owned and used six different phones and four other tablets. None of those forums even approach the quality of support that exists for this one. My new tablet was released in July 2016 and there are still no custom ROM's available for it.

But alas, the tasks I now perform on my tablet have become too demanding on its aging hardware. Many things I once did on my desktop or laptop have now become a part of my daily routine on my tablet. So the upgrade was way past due.

That said, is anybody interested in a heavily used (but still in good shape), TF300T? There are a couple of small scratches on the screen but they are not visible during use. The battery in it still holds a charge for a decent length of time. It is also the version that seems to be immune to WIFI issues. I have NEVER had my WIFI drop out while I had a strong signal. I also have a keyboard/docking station but the battery in it no longer charges, though the keyboard still works. In addition In have a TF700T that has barely been used. I wanted to offer them here before listing them on eBay. Make me offer. I need enough to cover shipping and give me a few bucks in my pocket but no reasonable offers will be refused. Also use private messaging if you are interested. Let's not clutter up this thread.

[Transformer TF300T Android Development] yannmrt:
Thanks for the advice, like I said i didn't format my self cache on f2fs but TWRP did it when I ask to wipe. (or may be i did some thing wrong as well).

Could you tell me in which format this need to be, Ext4 ? FYI i just check the cache format and it is ext3 even if it is format with mke2fs which is different that when you format in f2fs ecause twrp use mkfs.f2fs

thanks for your time.
[Transformer TF300T Android Development] MiniBlu:
Yes, it should be EXT4. Wipe cache just formats cache to same format it is already in, so you must have already had cache as f2fs before starting the process. Just format cache to ext4 and then future wipes will format it that way as well.
[Transformer TF300T Android Development] pe1dnn:
I think TWRP looks at the type of file system you have and then formats it using the same file system. So it formatted with f2fs because it was already f2fs. Maybe you changed it at some time in the past? Anyway, format to ext4, if you do then next time TWRP wipes it, it will use ext4 also. In other words, wipe just wipes (and for speed uses format to do it which as bonus also fixes any corruption if present) but it does not have the side effect of changing your file system along the way.

Hi

I decided to try this Rom after reading that the battery lasts long but after installation the battery says only 3 hours which is weid and I have more than 90% of battery for both tablet and docked

I did a full wipe and installed Nougatella then SuperSu then Gapps then Wipe Cache and reboot

But the battery says only 3hr with more 90%

I use to have more than 10hrs with stock rom

Any idea where is the issue?

I go back to stock rom again I think this rom is more a p.o.c than a Stable RC Rom

Just curious as to people's tab settings for best performance, mine has been lagging something fierce, lots of "(app) is not responding" "close or wait"...
[Transformer TF300T Android Development] AizenKnower:
I totally agree

After installation from full wipe the battery says only 1h30-2hr without dock (with only 2hr)

But I also have like you some lagging and not responding/closing.

I am also wondering how they installed it and setted up. It should have a clear tutorial to install it and set up it for best performances.

Only 3h of battery with dock and sole lagging or not responding apps and I always come back to stock rom because with all this issues I wonder How People can use a Katkiss rom or How they set it up or install it. But nobody explain in details

I dont criticize or blame anyone I just confused and curious how people can say it is stable or no issue of battery or app responsiveness when a clean install from full wipe bring a huge drain battery of only 3h (docked with bluetooth and location and network all désactived)

I think a detailed tuto on how to install et set up will be welcome to have an unique tutorial for best performances.

I wanted to try this rom because in an other post someone but a screenshot for the battery lasting more than one day but in my case only 3hr

Any idea where is the issue?

Thanks
[Transformer TF300T Android Development] timduru:
Defaults settings are already set for best performance.

If you have apps not responding it usually means that something is acting up, usually gapps / mediascanner or another app using heavy I/O

or your storage locking up.

Lately if you dirty flash a too old version of gapps on top of an updated one it tends to barf.

No easy solution other than clean flash.

Can't trust battery stats after a fresh install, you should also let it settle down as things are updated / mediascanner scanning all your medias again.

If you have a lot of medias, you might want to set mediascanner filters.

They most likely bothered reading the 1st & 2nd post ;)

Also make sure that you formatted /data to f2fs

(and not only did a "full wipe")
