Thanks, I saw that link in your earlier post but was hoping to get the version of CWM that works with this. In any case that TWRP build worked and I'm now in the spinning arrow phase of loading CM. It's been here a couple times now and both times when I I returned to the tablet it was powered off and it restarted this process when I booted it. Hopefully it finishes at some point...
[Asus  Eee Pad Transformer Prime] primerars:
Everything is now working fine. Took few minutes after flash for play store to work though.

Thank once again OP

This happened to me and I redid the entire process and it worked the second time around.
[Asus  Eee Pad Transformer Prime] zj4x4:
I tried reloading everything and still got the unending spinning arrow on the CM logo. Any other ideas?
[Asus  Eee Pad Transformer Prime] Bastaerd:
On other devices it can be because boot.img is not (correctly) flashed due tot various reasons. Would be interesting tot see what last_kmsg says (in TWRP, use file explorer to get it after a bootloop).

Thus, dirty flashing the ROM again or flashing the boot.img could solve the bootloops.
[Asus  Eee Pad Transformer Prime] Namidairo:
Got a little bored, put together a version which uses F2FS on /data and /cache

cm-11-20141104-UNOFFICIAL-tf201.zip

And there's a recovery uploaded in the download section of this thread.

Best not to flash this unless you know what you are getting into. Ie. You have to format /data and /cache, including the /data/media storage. (I did it via adb shell in recovery with mkfs.f2fs on /dev/block/mmcblk0p2 & /dev/block/mmcblk0p8)
[Asus  Eee Pad Transformer Prime] Epic 4g:
Ok, I have neglected my Transformer Prime & all I have been doing the last 2 weeks is catching up on the bootloaders & 4.4.4 ROMS. I am patiently waiting for the Google Nexus 9 to come out in the Sand color, so I want to update my Transformer Prime to 4.4.4 so I can give it to my boys so they can play games & play all my 300+ games I have on my NES, SNES, Genesis, & N64 emulators. (It's part of my video game education.) :D

I am on Energy ROM but the 4.1.1 build. I take it I am on the 4.1.1 bootloader cause I never updated to Energy ROM 4.2.1. build. It says in the Energy thread that the 4.1.1 build runs on the 4.1.1 bootloader & that the 4.2.1 build runs on the 4.2.1 bootloader, that pretty much sums it up for me. Also I used to flash between Energy & CM when I was heavy into the Asus Transformer Prime.

So all I need to do is update TWRP to the most current build 2.7.0.0 & then flash this CM11 ROM & I should be on 4.4.4 KitKat. I feel strongly that, that is the way to go. Also is there anyway to tell what bootloader you are on? :confused: Other than that, I feel very confident, I just want anyone who is still active on the Asus Transformer Prime to give me a heads up just to feel better. lol This tablet when it came out was my pride & joy. I loved it, & it turned into a virtual console for my kids & I for a long while. Now I want to update to 4.4.4 KitKat to bring new life in to this classic of a tab.

Thank you so much to anyone who can assist. :good:
[Asus  Eee Pad Transformer Prime] billycar11:
i got this running, it is quicker to open apps otherwise the same.

but i have a question is this a one time type of build or will the newer lollipop versions also have f2fs support?
[Asus  Eee Pad Transformer Prime] Namidairo:
Probably going to make the lollipop builds f2fs, as my experience seems to be positive.

This is your warning to backup your stuff guys :p
[Asus  Eee Pad Transformer Prime] Xerxes-3.0:
<breathing intensifies>
[Asus  Eee Pad Transformer Prime] feyerbrand:
I literally was looking into forking a build of lollipop from the nexus 7 because I have no clue how to develop haha. I am glad to hear that you are working on a F2FS version. Does this mean you are going to develop for the other bootloader version?
[Asus  Eee Pad Transformer Prime] Stargazer Optimus:
I don't know about anyone else but this f2fs version seems to solve a problem of lag fo me when typing into or using delete in a search box.

I ran androbench and A1 SD benchmark tests on the internal NAND before and after changing to f2fs and have found the read speeds to be slower but the write speeds to be faster.
[Asus  Eee Pad Transformer Prime] Ruben Gomez:
Hi thank you for this build! Is it compatible with the TWRP recovery you pointed out here?
[Asus  Eee Pad Transformer Prime] Namidairo:
Should be, haven't tested. Just check for the presence of mkfs.f2fs
[Asus  Eee Pad Transformer Prime] zj4x4:
Thanks [MENTION=4224959]Bastaerd[/MENTION] for the reply, I'm getting back to this now that I'm home again. I got the last_kmsg file via adb but there's a lot of data in there and I'm not sure what I'm looking for. Any pointers? Or should I just upload the file?
[Asus  Eee Pad Transformer Prime] Epic 4g:
Ok I am really loving the new life Android 4.4.4 KitKat has given my Asus Transformer Prime. It's almost like using a new tablet. Sure the hardware is going on 4 years old but I am so surprised on how much of a difference in speed there is going from Android 4.1.1 to Android 4.4.4. Thank you so much for this Namidiaro. :good:

The only issue I have is that my contacts app keeps on force closing. Is anyone else having this same issue? Also is there a remedy for it? :confused:

Everything else seems to be working very well. I haven't had any other issues. The camera takes some pretty decent pictures for again an almost 4 year old tablet. I have to admit I am quite impressed. :D

Any help with the contacts app force closing will be GREATLY appreciated! Thank you!
[Asus  Eee Pad Transformer Prime] Bastaerd:
Upload the file and I'll take a look

Edit: ArsTechnica just wrote an article about Lollipop on the Nexus 7 (2012). Since we are rocking similar hardware it is worth reading. Bottom line, where I am from, we say, a cow in a dress is a cow in a dress. Bummer!
[Asus  Eee Pad Transformer Prime] Xerxes-3.0:
I really do hope that f2fs will improve the performance a bit, right now I have second-long lags on almost everything I do with it. Also, it reboots randomly.

If not, there is an Xperia Z2 tablet.
[Asus  Eee Pad Transformer Prime] adamforeman:
[MENTION=4460243]Namidairo[/MENTION], as Xmas is here, will we see beta's of Lolipop in the new year?

Cheers for this ROM again. It's breathed new life into my old tablet.
[Asus  Eee Pad Transformer Prime] Xerxes-3.0:
This is also relevant to my interests.

Eventually, I got myself an Xperia Z2 Tablet, but I want to give the Prime to my parents, who totally don't need a tablet (we will see about that :D).

So there is just the question: wipe with current non-F2FS-KK and leave it, and maybe upgrade later, or wait for Lollipop? Not that a few days matter, I'm just curious.

Al already have the according recovery and ROM, but then?

Just flash the recovery and then format data and cache with f2fs?
[Asus  Eee Pad Transformer Prime] Xerxes-3.0:
What could possibly go wrong?

I just tried it and it works, much easier than expected.

Flash the recovery, format /cache and /data and then install the ROM via sdcard as usual.

However, I had the error "cannot mount /data" and therefore could not just format it. However I could format /data and /media (I think) and that worked instead, without having mounted /data before. Hm.
[Asus  Eee Pad Transformer Prime] Xerxes-3.0:
Okay, after setting everything up, I would say everything is a bit more fluent.

Or, if it is not everything, it feels like that because the lags are mostly gone.

Great work! :good:

/e. For some reason, it did not want to play notification sounds and such. Just didn't. When I navigated to the folders with ES File Explorer, all files where there. And afterwards it worked. Trololo.
[Asus  Eee Pad Transformer Prime] Namidairo:

Only things I have working at the moment is it booting, sound, bluetooth and wifi...

I can probably do the camera fairly quickly, not sure what's going on with the h/w accelerated decoding...

Whoops missed a patch, camera and h/w accel work now.
[Asus  Eee Pad Transformer Prime] suhiSLO:
A nice red and white download button with lights and snow on top would be nice. I see you got most of it working .:D
[Asus  Eee Pad Transformer Prime] Aegison:
You are truly an amazing person Namidairo!

How is the performance? After reading reviews of 5.0 it seems all the fancy "physics based" animations would be too heavy for our Tegra 3.

Also, this may be a stupid question but will we lose everything with the update and have to restore from backup, or can we "upgrade"?
[Asus  Eee Pad Transformer Prime] zj4x4:
[MENTION=4224959]Bastaerd[/MENTION] - sorry for the lengthy delay and thanks for the help. The kmsg file is attached.
[Asus  Eee Pad Transformer Prime] guy_smiley:
No such thing as a stupid question...

As with any change in framework, a full wipe is required.

By the look of it, Google have redesigned the way apps etc, are filed in \system which means a dirty flash (or "upgrade") won't work. It really isn't that hard to do a backup of apps using TiBu or other such programs, plus when they're updated, they will automatically put things in their correct place.
[Asus  Eee Pad Transformer Prime] jonoxda:
It would be so epic with a lollipop build. My little daughter uses the tf201 still, and not having to buy a new one helps the family immensely! Thanks for your great work [MENTION=4460243]Namidairo[/MENTION] !
[Asus  Eee Pad Transformer Prime] NismoR31:
I've been running this since a couple of days after you posted it. It's like a new tablet. Most other ROMs I've had on my TF201 have eventually slowed down to a crawl whenever it was interacting with flash. Wiping caches never helped etc etc. With F2FS it's a new machine!
[Asus  Eee Pad Transformer Prime] Ruben Gomez:
I've already discovered that ftrim is not working in an encrypted /data partition, it's a pity it makes the tablet a bit useless after some weeks, seems to be related with the dm-crypt version (issue obsoleted by Google BTW).
[Asus  Eee Pad Transformer Prime] Namidairo:
Nvidia seem to have reverted it in the L4T kernel source that my kernel is based off of.

https://github.com/namidairo/android_kernel_asus_tf201/commits/cm-11.0/drivers/md/dm-crypt.c

...and on Grouper/Nexus 7 2012 too.

I'm sure they had a good reason. Maybe.
[Asus  Eee Pad Transformer Prime] Racker_CRO:
Well after reading whole thread I decided to try it on my stock TF201. I've downloaded

recovery-f2fs.img

cm-11-20141104-UNOFFICIAL-tf201.zip

Is this all I need? Also at first post you wrote "NVFlash blobs and images retrieved from device and backed up, see second post." but I can't find it? How to do this?

Thank you.
[Asus  Eee Pad Transformer Prime] wickid_d:
For nvflash, do a forum search for "nvflash general users guide" or Google "androidroot TF201" - either guide will work, and frankly, the androidroot guide will get you the files you need to get out of practically any brick situation short of taking a hammer to the thing, lol. Also, when flashing a recovery from fastboot, don't forget "fastboot -i 0x0b05 recovery (name of recovery)" If not, and you have not already gone through the nvflash process, you'll be in a hard brick and have to replace the motherboard, should you 'reboot to recovery' from a running system.

Finally, no, that's not all you'll need for using F2F.ileS.ystem. You'll need a compatible kernel for that, namely Geass, Grimlock, or _that. The default CM11 kernel isn't compatible. If you want to use the normal file system, basically any kernel will do, including the default CM11 one.

Hope that helps.

~Wickid~
[Asus  Eee Pad Transformer Prime] Racker_CRO:
Thank you for nvflash explanation. Regarding F2fs i thought this is all I need as in one of the posts Namidairo says "Got a little bored, put together a version which uses F2FS on /data and /cache - cm-11-20141104-UNOFFICIAL-tf201.zip".

PS: just checked androidroot and it seems I can't do it on my TF201

*** For TF201: If you upgraded to Offiical JB it *won't* work!
[Asus  Eee Pad Transformer Prime] Bastaerd:
If my memory serves me correct Wheelie is for ICS, Flatline is for JB ;)
[Asus  Eee Pad Transformer Prime] wickid_d:
Ahhhh, well, I haven't been around for a while, so I missed that post from Nami.. Then you should be ok as far as that goes.. And np on the nvflash, but there is an updated guide on androidroot that tells about using the flatline recovery to get what you need. Google "androidroot flatline tf201". That should pull it up as one of the first few links.

Hope that helps.

---------- Post added at 04:26 PM ---------- Previous post was at 03:53 PM ----------

Wheelie is just a tool for beginning access to nvflash, whether in the file gathering process or the revival process, but yeah, it's part of the process for the ICS bootloader. I tried to use flatline on ICS and it gave me some error about not being on the right bootloader, lol.
[Asus  Eee Pad Transformer Prime] Racker_CRO:
Great! Thank you for your assistance. I've downloaded all files needed and as soon as I back up all my data I will try it.

How update the version of the room

Hello everyone,

idk if this is the best place to ask but can someone tell me the steps necessary to update my version of this room, wich is cm-11-20140610-UNOFFICIAL-tf201 , to the last one cm-11-20140926-UNOFFICIAL-tf201 whitout loosing files and stuff?

or i need to full wipe?

i take so many time configuring everything that i don't want to loose it when upgrade :)

By the way, my version have a little annoying bug, sometimes i cant display the shutdown menu so i need to shut it from "terminal". The new version have this bug corrected? or have any annoying bug that im not aware?

Really appreciate your answer and thanks in advanced :)
[Asus  Eee Pad Transformer Prime] wickid_d:
Not a problem at all! :)
[Asus  Eee Pad Transformer Prime] Racker_CRO:
So I've managed to backup blobs and images. I've upgraded new CWM from Namidaro cm-11-20141104-UNOFFICIAL-tf201 and installed pa_gapps-modular-nano-4.4.4-20150106-signed. After successful boot enabled ART.

So far my observations:

a) boot time and apps installation is longer

b) once booted system seems faster and more fluid while swiping

c) I have a lot of FCs (ART related?)

d) right mouse button doesn't have functions when connected, before it was back button

e) is there a way to increase grid size in app drawer? There is a lot of space between apps icon

f) after boot I can enter PIN via my dock keyboard but after lock keyboard is not working anymore for PIN, I need to tap numbers on screen with my finger

g) one thing I noticed in terminal emulator...my system partition is ext4 but data and cache are f2fs - screenshoot. Did I miss something like formatting system while in recovery??

h) ...

Regards.
[Asus  Eee Pad Transformer Prime] wickid_d:
ok, I hope someone else jumps in here and answers what I can't because I haven't used Nami's rom in a long time.. (I've got a really advanced install going on, on mine)..

I'll just take what you have and see what I can do:

a & c - both maybe ART related, the FCs are for sure because I remember the same happening to me with a lot of apps.. ART runs better on Lolli.. and the initial boot will take a bit longer due to the system rebuilding the cache

d & e, look around in settings, for d, I ran into the same, I do remember that - grid size, I'm pretty sure, is in the trebuchet settings under Home.. if not, you can always use an alternate launcher such as Nova or Apex.

f - that's odd, but then again, i only use the slide lock on my tablet or phone.. I have no need for a pin or password.. [MENTION=4460243]Namidairo[/MENTION], care to comment on why he's running into this?

g - that's more than likely done during install, that it formatted that way, if that's how Nami set up the install script on the f2fs version

h? lol umm.. Not sure how to respond to that one.. I guess.. ...back, lol

Hope that helps! :)

~Wickid~
[Asus  Eee Pad Transformer Prime] Racker_CRO:
Wickid you are awesome! So back to my issues

a & c are sorted for now. I reverted back to Dalvik and system is more stable. So far not one FC

d & e are nowhere to be found. There is no option for Trebuchet settings for app drawer, only Lock, Notifications & Status

f is not big issue, rather "would be nice to have" feature

g - thanks for clarification

h was there as empty space if I think of something else or if someone has something to add :laugh:

Now I need to test HDMI out. I hope it works because I use my tablet from streaming movies in my bedroom from my Mede8er in living room :D. One nice feature is that Kodi in this release is in full screen once started. On stock rom I had to use fullscreen app from store (buggy I must admit).
[Asus  Eee Pad Transformer Prime] Namidairo:
I left system as ext4 as the vast majority of the time it's mounted as RO.

ART FC's? Can't really tell you what's going on without a logcat.

Yes, it takes forever in lollipop. *FOREVER*
[Asus  Eee Pad Transformer Prime] wickid_d:
Nah bro, I was talking about the pin/kb probs he was running into..
[Asus  Eee Pad Transformer Prime] Ruben Gomez:
Hi I've sucesfully installed the f2fs version of the ROM by Namidairo (thanks!) the problem is that my tablet is still lagging a lot, specially waking up after a few hours in suspend state. I did a fresh install, (just recovered user apps with Titanium B), did the f2fs format of /data and /cache, and manually trimmed /system.

I'm adding an Androbench capture, does the numbers look good to you? I previously encrypted my tablet, in an older installation, lagged a lot, discovered that trim wasn't happening, and then installed this.

PD. I'm using ART, BTW.

UPDATE: I read some complaints in thread about ART, switched to Dalvik. Wow man the thing now really flies! I don't know whats happening inside, but the difference is night and day. Never saw my Prime running so fast.
[Asus  Eee Pad Transformer Prime] Racker_CRO:
I agree! After reverting back to Dalvik from ART my Prime is just amazing! Fast, responsive, with more than 40% of free RAM at any given point! For past two months I've been searching for new tablet (my Prime would be kids tablet) but after this upgrade I will keep it for a long time.

Thank you Namidairo and wicked!

UPDATE: Also, I would like to add that WiFi quality has improved. In some places around my house I had 3 bars now I have 5. I'm using repeater in my bedroom and before I had to disconnect and reconnect few times to get the signal from repeater (it was connecting to my main router with 1 bar only). Now it changes to repeater automatically and vice versa.
[Asus  Eee Pad Transformer Prime] elgordo123:
Sorry to ask a possibly dumb question. - At first you stated "that is all you need", but then you state you need a compatible kernel... So we "do" need a compatible kernel in addition to the recovery and the rom (the f2fs rom) correct? If so, you pointed out a couple, which one is recommended/most popular for this rom?

EDIT: Nevermind - I downloaded Geass "normal" and everything is working great. Thanks for this incredible ROM!
[Asus  Eee Pad Transformer Prime] wickid_d:
If you followed everything closely, the responses had changed because Nami had posted a version of the rom that used f2fs by default, that I was unaware of because I hadn't been around in a while. (Please see the attached, cropped, pic of the screen shot I just took.)

However, I'm glad you got it fixed for your situation! :)
[Asus  Eee Pad Transformer Prime] suhiSLO:
Any news on cm12 maybe?
[Asus  Eee Pad Transformer Prime] wickid_d:
Just to add to my last post: (sorry, I was in a grumpy mood in my last post..) Yeah, Geass is what I run for kernel, and love it! :) Only drawback is, if you try and do rom2sd, it won't work for it.. at least, *I* couldn't get it to work for it.. your mileage may vary.. :P

---------- Post added at 06:24 AM ---------- Previous post was at 06:17 AM ----------

Doubtful, considering I believe at one point in this thread, [MENTION=4460243]Namidairo[/MENTION] said he wasn't updating this (even though he whipped up an f2fs version, lol). Nami, please correct me if I'm wrong.. but really, I'd love to see a CM12 release from you, myself! :P The Lolli release (notice: I didn't say CM12, it's some other rom with a dog on the bootup logo) on the 300T forum is pretty buggy, to say the least..
[Asus  Eee Pad Transformer Prime] CRACING:
Dude, Its a Katkiss ROM.

Have you tried ZOMBi-POP OMNI? Its less buggy and the power off issue is fixed (That used to reboot on Katkiss). Only that the device soft reboots some times and its said to be OMNI kernel issue. Hope it will be fixed eventually though.
[Asus  Eee Pad Transformer Prime] Namidairo:
Yeah, I'll post a zip on the weekend or something...

Although I probably shouldn't post zips with selinux set to permissive, and allowing non-PIE objects.

I've pushed most of it to github, but there are a whole lot of patches that it depends on to run, quite a few of which I am unsure will ever be merged. (Quite a few of which would not be needed if Asus had released a 4.2 rom like they did for the rest of their Tegra 3 lineup...)

On the plus side though, at least I don't have to ship multiple zips for ext4/f2fs versions as the recovery and rom handle multiple fstab entries now.
[Asus  Eee Pad Transformer Prime] wickid_d:
Thanks.. I couldn't remember the name exactly, lol (not to mention, I only had a few minutes to post and didn't have time to look it up..) Thanks for the heads up, I'll have to check it out! :)

[Asus  Eee Pad Transformer Prime] dragonfly1113:
My prime is still stock and on jb. I have unlocked it and installed twrp 2.2.2.1 will this install this rom? I saw people post it only works with certain recoveries but this was the only version I could find that didn't hang at the 4 icon screen saying booting recovery kernel.
[Asus  Eee Pad Transformer Prime] Bastaerd:
Did you try Voyager2K's TWRP? Newer then TWRP 2.2.2.1 and it works (at least for me :P).
[Asus  Eee Pad Transformer Prime] dragonfly1113:
I'll try that today. Thanks.
[Asus  Eee Pad Transformer Prime] wickid_d:
As long as you use the following format (minus the single quotes and put the name of the recovery you're flashing where appropriate) : 'fastboot -i 0b0x05 flash recovery name-of-recovery' you shouldn't have any problems flashing any version of twrp based on the jb bootloader.. ;)
[Asus  Eee Pad Transformer Prime] dragonfly1113:
ok got the voyager twrp to install, than installed cm11 it seems to have went through fine, how long does initial boot take? i have the cm boot logo for about 10 mins now just circling around. i did try installing gapps after installing cm11 but it failed due to a space issue, dont think that would cause this screen to get stuck though.

debating if I should just restore my recovery i made from the stock rom.
[Asus  Eee Pad Transformer Prime] wickid_d:
Initial boot can take up to half an hour, but as far as gaps failing, if you used the version from June last year, no, it won't fit. Try the one from February (March maybe?) From the cm wiki. May not look as pretty, but will get you booted for sure.
[Asus  Eee Pad Transformer Prime] demifalcon:
Could someone help me over here?

I've been looking for stable ROMs all day and I made a thread, but no one's replied....

Here-http://xdaforums.com/transformer-prime/help/fastest-stable-rom-available-kernel-t3061847

Is this ROM considered fast and stable for daily driver use?
[Asus  Eee Pad Transformer Prime] Ruben Gomez:
Yeah the Kitkat's f2fs version available in this thread is incredible snappy, and completely stable IME. Way better than the official ASUS Rom. I recommend you to use it with Dalvik though. ART didn't worked properly for me and others in this thread (but other people, see below, seems to be fine with it so YMMV). Also avoid encryption, I already messed up my tablet trying it.
[Asus  Eee Pad Transformer Prime] Bastaerd:
What are the problems with ART? ART worked fine for me.
