Still can back to ext4. May be the step wrong.

1. flash Custom TWRP v2.7.1.x JB/KK enabled for TF300T/TF201 [without any device checking] | F2FS TRYOUT (2014-08-27) <= For use if your /data is F2FS formatted !

2. Select Wipe and Swip to Wipe

3. In Advance Wipe select Data and Swipt to Wipe

4. flash Custom TWRP v2.7.1.x JB/KK enabled for TF300T/TF201 [without any device checking] | F2FS TRYOUT (2014-08-27) <= For use if your /data is ext4 formatted !

5. Format data.

Unsuccess.
[Transformer TF300T Android Development] ne0zone75:
Disregarding your current recovery :

-> flash a standard EXT4 TWRP build of your choice ! (optional if you have already flashed one)

-> usual steps to convert a filesystem to another one (F2FS to EXT4 in your case, from 'wipe/advanced wipe' menu...)

And you are done !

NB : Please leave any F2FS recovery build away ! It can be done with it BUT that is far from mandatory...)
[Transformer TF300T Android Development] z1022:
flash stable EXT4 TWRP build from you.

when wipe.

Show error

E:Could not mount /data and unable to find crypto footer.

E:Unable to mount '/data/'

.

The reason should be cannot mount /data when you standard ext4 twrp.

Any other method
[Transformer TF300T Android Development] ne0zone75:
At we speak, is your /data partition an encrypted one ?! (F2FS)

If this is the case hit the cancel button when TWRP asks for a password , then proceed with steps from my previous post !

BTW i really do not understand why you have such difficulties to go back to EXT4...

I really do think that you should ask for assistance from the CROMBi-kk team if you do not make it !

Good luck !

Updates release is delayed a little bit...

Good evening,

TWRP updates for TF300T will be released early next week instead of this weekend... no enough freetime for everything to be done ! :confused:

Be well !

Post #1 is updated !

Good evening,

Post #1 is updated with new download links (AndroidFileHost) for both STABLE & DEV branches; TRYOUTS are still there as a fallback and they will be removed shortly if everything works as expected...

NEW !!! : From now on, every flashable .zip files from me will be signed ! The first 2 ones are those released today ! :cowboy: :cool: :good:

:fingers-crossed:
[Transformer TF300T Android Development] das chaos:
Good evening!

Please reconsider the naming of your download files. At least the Tryouts work for both tf300t and tf201.

Edit: Also the 'dev-branch' version works for tf201 flawlessly.
[Transformer TF300T Android Development] ch3mn3y:
I dont know if anyone has similar problem like me, but when i try flash DEV one (newes 0903) using TWRP i have now (2.7.0.0-geass f2fs) I doesnt flash even I get Successful (no twice reboot and after reboot its still geass one).

Probably using fastboot will work, but would like to know whats wrong that i cant flash it "normally"
[Transformer TF300T Android Development] das chaos:
Indeed I had the same problem when trying to install via recovery.

Normally I install however via terminal emulator (or console in recovery) unpacking the zip and staging recovery.img with

dd if=/storage/emulated/0/recovery.img of=/dev/block/mmcblk0p4
[Transformer TF300T Android Development] ch3mn3y:
Never thought about using Terminal to flash something. However needed to use /storage/sdcard1/recovery.img as with /emulated/0 i always got cant read, no file or sth like that.

Now i have different question: Using this recovery can i change filesystem of /system or /cache? I know im doing it on my own responsibility, but before i would like to know if it (1) works and is meant to be used (not future addon, which part we can see now), and (2) is "restore backup" (didnt know how to call it) using make-f2fs or something which leave partition as f2fs when restoring backup? That way i would need only make backuo->format->restore and voila, everything is back ;)

[Transformer TF300T Android Development] das chaos:
Don't know why you can't stage via terminal. /storage/sdcard1 with command dd won't work, because sdcard1 is vfat, but /storage/emulated/0 should work (if you have unzipped recovery.img there).

(1) You can format with ne0zones TWRP any partition with f2fs. But it makes sense only with /data partiton as long as there are only kernels that cannot handle 'all-f2fs'.

(2) As f2fs is an encrypted filesystem, you can restore to f2fs partitions only encrypted backups. Howewer I think there is an option in the tab 'advanced' to switch to non-encrypted backup. Didn't try that.
[Transformer TF300T Android Development] ch3mn3y:
For me sdcard1 worked even if its vfat, but internal didnt want, but important is that it worked (at least).

(1) so maybe i will try other partition just for myself to found pros and cons

(2) didnt even now about possibility to encrypt backup so dont know if i used it or not

Thanks for all answers

[Transformer TF300T Android Development] das chaos:
Don't! If you format /system to f2fs, ROM will not install! If you format /cache to f2fs, apps will not be initialized (see warnings in attached screenshot). The advanced speed of f2fs only make sense with /data, otherwise devs would have applied it to other partitions. 'All-f2fs' systems exist only for some devices (I think there are some on Nexus, don't remember).

on scanno's 2.7.0.1 twrp the dock keyboard functions in twrp, I havn't tried the last twrp that ne0zone75 has released, but the first ones the dock keyboard would not work in his twrp.

Hello,

Just a little post to let you know that today i will probably build TWRP 2.8.0.0 (source code has been merged upstream recently) for TF300T/TF201.

My very best regards
[Transformer TF300T Android Development] scanno:
The source code is building, if it is booting is another question. FYI each time i make a build, the TWRP source code is building also and if there is an error in building, it would not result in a finished build. The last time i build for TF300T was 7 days ago.

Regards,

Scanno

---------- Post added at 01:54 PM ---------- Previous post was at 01:38 PM ----------

In the BoardConfig.mk the default TWRP keyboard layout is overwriten by a device specific one.
[Transformer TF300T Android Development] ne0zone75:
Hi,

Are you saying that your 2.8.0.0 builds are not booting ?!

Which specific hardware keyboard layout are you using please ? My builds are using the one embedded into TWRP sources tree (located in /bootable/recovery/gui directory) and AFAIK dock keyboard was working...

My kindest regards

PS : Anyway, i am already checking all build items out and i do think that new builds will be offered as TRYOUTS later today...

Stay tuned !
[Transformer TF300T Android Development] das chaos:
[MENTION=5280400]ne0zone75[/MENTION]

dev, please check your zips. The last ones, as some user mention, don't flash via discovery. I myself apply them via terminal emulator, so I don't have that problem, but I tried the last Dev-branch just for science to flash via recovery and it won't stage; maybe check meta-infs/installation scripts.
[Transformer TF300T Android Development] ne0zone75:
Hi and thanks for your feedback,

I have already took it into consideration... but i am currently at the updates building step ! :angel: ;)

BTW, as you already know i cannot test new files out by myself because i do not own any device that matches my current projects over xda anymore... (i only own a TF701T ATM)

Finally, for the issue you are referring to, i will double check every upcoming release before it goes to TRYOUT section...

TWRP 2.8.0.0 is booting, but i have display problems (same as with 2.7.1.0) while using my omni tree.

If you have an image, i can test if you want
[Transformer TF300T Android Development] ne0zone75:
Of course Yes ! I do accept with great pleasure ! I will send you a restricted Google Drive download link as soon as it is built (EXT4 version). ;) :good:

Now..., are you using the 'RGBX_8888' flag by any chance ?! If it is the case, i would suggest that you try to build again without it... because it was causing weird display issues for me when building along with CyanogenMod's sources...

Allright, thanks a lot [MENTION=905572]scanno[/MENTION] for your feedback !

I will set font size a little bit lower... and i renamed the display name of every partition and it was a bad idea because now both /data and /data/media do appear with the same name... :confused: => fixed and rebuilding ATM...

Anyway, download links are updated on post #1 for 2.8 (xda downloads tab will be updated later) and these links will be updated again today with both branches recompiled and fixed ! Then, if there is no reason to keep 2.7 fallback (you will tell me) -> TRYOUTS links will be removed !

Your are talking about microSD or dock SD one ?!

FYI dock SD card must be inserted in its slot before trying to boot TWRP, otherwise it won't mount...

Is your SD card was previously working with recovery ?!

Have a nice day :D

micro sd card i do not own the dock is working in a rom just not in twrp

when you go to mount all it says is error mounting sd card

so when i installed a rom i copied it to internal only way i could do it
[Transformer TF300T Android Development] ne0zone75:
Well, it happens sometimes... simply reformat it to FAT32 from Linux if you can or perform a regular FAT32 formatting (not a quick one) from Windows...

Let me know if this helps...

PS : In addition you may post the recovery log too... to find out what is wrong with your microSD card...

Good afternoon,

I will offer updates of all files soon... (EXT4 and F2FS)

Could you update TWRP for TF300T basing on new 2.8.0.1 available on teamWin site

http://techerrata.com/browse/twrp2/tf300t

Which format is .blob?

Could you implement small changes to your file like

include in the name of zip file the version 8ex. 2.8.0.0) and date (as yyyymmdd) to check which version is.

Like (ex.): TF300T-recovery-TWRP-2.8.0.0-20140902.zip

And if you can please don't change the recovery.img file date inside the zip to 29.02.2008 (it's impossible to find the real date/version of the img file).

Thanks.

Thanks to accept my consideration.

I used the zip file of 2.8.0.0 (renaming the 2.8.0.1 .blob file downlaoded by teamwin site in recovery.img and replacing the file inside the zip) and it works.

Please if you can update the first post with the info about 2.8.0.1 and post the zip file to update the current recovery (not stock) with the new TWRP 2.8.0.1.

New TRYOUT builds are online !

Good morning,

TWRP 2.8.3.0 updates for TF201/TF300T are now available for download from AFH. There are a few things to know about them before flashing... :

-> they are built from omnirom kitkat sources (i never built from those before...) BUT TWRP sources come from the omnirom android-5.0 branch

-> they are TRYOUT builds : simply report any issue in this thread, thank you !

-> EXT4 version has full crypto. support

-> F2FS version does not have any crypto. support

-> dock hardware keyboard should work...

Huge thanks to [MENTION=5123642]lj50036[/MENTION] ! I added the F2FS functionality for /data to the omnirom kernel for TF201/TF300T by using several commits of his personal github repositories...

=> TWRP 2.8.3.0 EXT4 TRYOUT

=> TWRP 2.8.3.0 F2FS TRYOUT

PS : files are available as flashable ZIPs BUT you can also use the fastboot method described in the opening post of this thread...

NB : if these TRYOUTS are working as they should, they will replace files available in opening post of this thread in about one week, when feedback will be there...

Kind regards

On TWRP official site it's available an official TWRP 2.8.3.0 for TF300T.

Which are the differences between official and your builds?
[Transformer TF300T Android Development] ne0zone75:
Like it is stated, i am offering a F2FS version which is not the case for official builds; the EXT4 version should be nearly the same as TeamWin one except for the dock SD card which is supported in both builds of mine and not in official version...

[Transformer TF300T Android Development] ne0zone75:
Good evening and thank you for reporting back :good:

It would be interesting to know if someone else is having troubles for flashing my 2.8.3.0 ZIPs and if it is the case please specify which recovery is concerned with its version, thanks !

Anyway, the updater binary packaged in these ZIPs is the same for a long time now, maybe should i update it in order for those to be flashed by LP based recoveries...

As a workaround you can flash it using the fastboot method of course : if doing so please do remember that it is better to flash to /staging instead of flashing directly to any partition of your transformer pad ;)

Regards

Tapatalked from my XT1068
[Transformer TF300T Android Development] k-kuchen:
Could you please explain in detail what you mean? :)

I used "dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p4"
[Transformer TF300T Android Development] shawnbrennan55:
I get the same error.
[Transformer TF300T Android Development] ne0zone75:
So you did use the dd method (via adb shell) to flash the recovery image which was stored on the internal storage of your tablet to /staging (which is mmcblk0p4 block device) and this is another way... ;)

The fastboot equivalent would have been :

fastboot flash staging recovery.img

... from a linux shell where the recovery image is stored in the current directory on your computer... :p

So these two command lines above are usually preferred than flashing the recovery image directly to the recovery partition of your device (which is mmcblk0p9 block device), like this :

fastboot flash recovery recovery.img

... or

dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p9

Nice evening

Hello [MENTION=5280400]ne0zone75[/MENTION]

glad, you are back!

I am confused! Two weeks ago I downloaded TWRP 2.8.3.0 from official site (techerrata.com) and flashed it on my tf201 and on my tf700t; in both cases there is support for f2fs (tab wipe => repair fs => change file system)! Nevertheless I will try your's.
[Transformer TF300T Android Development] ne0zone75:
Good morning,

Yes ! You are right BUT it does not mean that official version is able to mount /data when it is F2FS formatted, it only means that official build is featuring F2FS tools...

-> F2FS tools are a set of binary executables BUT...

-> F2FS mounting is a kernel feature which lacks for regular kernels on a lot of devices including transformer pad ones.

I truly hope that you are less confused now ;)

Have a nice day !
