[MENTION=4460243]Namidairo[/MENTION]: I tried compiling cm12 twice yesterday. Both attempts led to a zip of the correct size but both of them would not flash due to a signature error. Googling the issue led me to posts saying I should disable signature verification in recovery but I don't think that's the issue since your builds flash fine. I think it's something with the updater script and will poke around some more with compiling roms.

This is my local manifest, used to pull the required files from your repo's:

<?xml version="1.0" encoding="UTF-8"?>
<manifest>

<remote name="namidairo"

</manifest>

Thanks for the 12.1 build, it flashed without problems. Noticed that the brightness slider has been fixed, awesome! 12.1 seems to work way faster but time will tell if it stays that way. Unfortunately, my tab cannot connect to a wifi network with 12.1. Tried deleting and re-adding wifi network but that did not work. Even a clean flash did not work, weird!

As for gapps, the gapps I found flashing without a signature error were the last 5.1 pico gapps by TKruzze. Link to thread where they can be obtained: click!

Edit: Third time is the charm. For people not wanting bleeding edge here is a fresh build of cm12: click!

Bootloader correct?

I have on mi tf201...

Android cardhu-user bootloader (1.00 E) released by "US_epad v10.4.2.18-20121122" A03

This is ok?? or I have to change it?? :confused:
[Asus  Eee Pad Transformer Prime] rameera:
the CM12.1 wow!

Thanks, Namidairo... I am very grateful :D. The 21 Mar version speeded up my system when wifi was on. I am sure this 12.1 version will be even better.

I put the file in a new folder I created on my TF201 called cmupdater, and the process of updating is simplified.
[Asus  Eee Pad Transformer Prime] frusso:
I think that the bootloader is OK (is more or less the same that I have).

After an half day spent to install this ROM at the end I win.

You MUST install the recovery in first post (it his a very rude recoverty) but after you can install the ROM.

For gapps be sure to install the pico version (only the market) released for 5.1 (and not for 5.0)
[Asus  Eee Pad Transformer Prime] rameera:
installation report

Further to my last post thanking you. A few points to note for others installing the 12.1:

>make sure you wipe dalvik and cache

>flash the rom

>flash pa_gapps_pico for 5.1( I had no system space for any larger gapps)

After the TF201 boots, it takes a few retries before it will connect to wifi - but once done there is no problem ever again.

The updating of the rest of your apps takes time - of course depending on how many you have installed on your Prime.... mine took a very long time as the downloads had to be helped along by stopping them and accepting the permissions maybe more than once.

But all done, it has ironed out all my problems and runs fast and smooth!

Thanks again.

Dock battery:

It's a few patches that need to be forward-ported in order to get it working.

Gapps:

We're too fat for anything larger than pico on our small /system partition now! (~500mb)
[Asus  Eee Pad Transformer Prime] gsanglan:
Very Very Responsive

Thanks for the new CM12.1!!! :good::good::good:

It make the tablet very very responsive, much faster compared to CM11 and CM12:laugh:

As pointed out by another user, I faced the same WIFI connection issue after the initial boot. I reboot again and re-try connecting to my router for another 10 times or so before it works. After that, it is working as normal.

Can't wait for the next release to fix the dock battery issue.:D

Update: Some further findings, the HDMI port is not working, and also the camera app died when I tried to switch between front and back camera. But this is overcome when I installed the Google Camera app.

How do I back up my current ROM with your recovery? I don't see an option for that?
[Asus  Eee Pad Transformer Prime] Aegison:
My settings is crashing every time I select Sounds. I am on the 405 update and recovery from this post.

Also, I now cannot seem to get it to connect the wifi. Yesterday I could try a few times and it would connect but now I have been trying over an hour and it just won't. I have not changed anything since yesterday.

Is it possible (recommended) to downgrade to one of your earlier releases?
[Asus  Eee Pad Transformer Prime] Fgarcor:
Did anybody tried by any chance the casting? I am curious. If the HDMI port doesn't work it could be replaced by it at least.
[Asus  Eee Pad Transformer Prime] -LeoN-:
Has anybody seen pit files / tutorials available to increase the system partition?
[Asus  Eee Pad Transformer Prime] gsanglan:
I've the same problem when I tried to select SOUND, the setting crashed out.

As for the WIFI problem, same here, it takes some time to establish the connection. I've found that if I pressed the ENTER key after I entered the password, and press CONNECT after that, it helps to overcome the issue most of the time. U can try and see how.

I also checked on other post in TF301 forum, and they mentioned that this WIFI problem could be kernel related as well, and the GRIMLOCK kernel has overcome this issue. I've tried to flash the lite GRIMLOCK 5.1 kernel on CM12.1 ROM, but it cannot work (goes into bootloop). So I am back to the default kernel for CM12.1
[Asus  Eee Pad Transformer Prime] Aegison:
I finally connected using the WPS button on my router. Once connected using that (without putting in my pass) it seems to reconnect no problem.

Anyone know of a way to turn off the typing sound without access to the Sounds settings? Even in airplane mode it still makes the weird "clop" sound when typing and opening/closing.
[Asus  Eee Pad Transformer Prime] jan3586:
Turn off sounds in the keyboard settings.

Screen Light OFF

When unlock my TF201 the screen light does not turn on :( I think it's not hardware failure because the Asus logo is displayed at startup...
[Asus  Eee Pad Transformer Prime] Aegison:
I had the same problem. I think it is just the brightness level not working. I can hear it take a screen shot when I press volume down and power. You can try blindly raising the brightness.

Also, thanks for information about the key sound jan3586!
[Asus  Eee Pad Transformer Prime] jesuspj92:
Screen Light OFF to ON

I found the solution to the problem of backlight. When you try to unlock the tablet, illuminates the sensor located next to the front camera with enough light for a few seconds and the backlight turn on... :good: :victory:

Stuck at boot Logo

Stuck at ASUS Logo,

Hey guys, I attemtped to upgrade my TF201 following the instructions in this thread, I was coming from CM11 device unlocked with TWRP 2.7.0.0

I had no dramas flashing the re3covery.img and I can get into the bootloader no dramas. I factory resetted then wiped the cache then installed CM12.1 from the SD card no issues, I then flashed the last good mentioned GAPPS in this thread. no issues so far.

When I rebooted the device I get the ASUS logo Blue bar thing that zips across the screen, it then displays the ASUS logo screen with the Nvidia logo and just sits there.

I jumped back into the bootloader and factory wiped again and cache and flashed just the CM12.1zip without the GAPPS and rebooted. It did the same thing again.

I cant get past the ASUS logo. any suggestions?
[Asus  Eee Pad Transformer Prime] gsanglan:
I recalled I faced the similar problem when I flashed CM12 for the first time. It got struck at the ASUS logo screen, and the Cyanogen boot screen did not appeared. However, CM12.1 is ok.

Anyway, I reset the tablet, and press the vol down and power button to boot into the bootloader (I am on CWM 6.0.5 recovery), then I choose the WIPE DATA option, and it go into recovery and wipe the data. This wipe took more than a few hours, I left it on overnight. There after, it boot into the google account setup screen when I checked the next morning.
[Asus  Eee Pad Transformer Prime] Bastaerd:
Cyanogen merged 5.1.1 last night, and for people wanting to try it out you can click this link ;)

Ofcourse I am not responsible for dead SD-cards, bricked devices, thermonuclear-war, etc. It boots just fine on my TF201. No changes except upstream changes.
[Asus  Eee Pad Transformer Prime] gsanglan:
Tried and working

Thanks for the quick update to 5.1.1. I've flashed it and it is working, even the sound issue go away with this update.
[Asus  Eee Pad Transformer Prime] RoBe30:
No luck with my 12.1,

I flashed CWM 6.0.5.0 and now I get a uncommanded reboot when formatting the data partition. I can format storage fine but the data will bootloop for some reason.
[Asus  Eee Pad Transformer Prime] Bastaerd:
Flash the recovery provided in the op and 12.1 should flash fine.

Was the GPS dongle fix not included in this build? (this one: https://github.com/namidairo/gps_wrapper_tf201)

None of my applications seem to recognize any GPS devices attached. It used to work in the CM11 build.
[Asus  Eee Pad Transformer Prime] Bastaerd:
Namidairo's or my build? I did not include it.

For the people wanting a fresh fix. Upstream changes + compiled with GCC 4.9.2 (since that's the default compiler in Debian Jessie :P).

Known bugs: finicky wifi
[Asus  Eee Pad Transformer Prime] unxconformed:
Oh, I was talking about Namidairo's. However, if you wanted to add it to your build, that would also be sweet! I use the GPS dongle for aviation navigation apps.
[Asus  Eee Pad Transformer Prime] Bastaerd:
Not sure if it will build but I'll give it a go Saturday.
[Asus  Eee Pad Transformer Prime] unxconformed:
Awesome, thanks!

I am currently on CM12...can i just flash 12.1 on top?

Also will i need to update gapps to 5.1? If so where can i download these for this rom?
[Asus  Eee Pad Transformer Prime] Bastaerd:
As you have probably figured out, my attempts to include the gps wrapper failed. I'll keep on trying but as always, time is a limited resource.

Since it's a new base, a complete wipe is strongly recommended. I use these gapps but there are others floating around. Keep in mind that we don't have that much free space so a minimal/nano gapps package is necessary.

For the trigger-happy flashers, here is a new build. Upstream changes, next build I'll try to include fiops io scheduler.
[Asus  Eee Pad Transformer Prime] mongrel43:
File Package Broken?

Thanks for all the work on this. The package from 22 April installed fine but HDMI and GPS have been a problem. Downloaded the file package linked above (from 30 April?) but the package appears to be corrupt? Zip won't install and won't open up either.

Thanks for this fantastic work,

Cheers

George
[Asus  Eee Pad Transformer Prime] Bastaerd:
Try re-downloading my build, it's probably a corrupt download. Don't forget to wipe if you are coming from Namidairo's builds since they are signed with a different key.

question about flashing cm-12.1-20150422-UNOFFICIAL-tf201.zip

Trying to flash this:

cm-12.1-20150402-UNOFFICIAL-tf201.zip

using TWRP 2.8.5.1@AREA51

f2fs format

As it flashes I get an error message:

This package is for device tf201: this device is tf201t

E: Error executing updater binary in zip '/external_sdcard/cm-12.1_20150422-unofficial-tf201.zip'

Does anyone have any ideas?
[Asus  Eee Pad Transformer Prime] Bastaerd:
You need to flash 4.1.1 (stock) bootloader than flash the provided CM recovery from the OP and after that ROM.
[Asus  Eee Pad Transformer Prime] bnoem1:
I guess this is what's confusing me. I am running the 4.1.1 stock bootloader. Is it possible that the recovery is changing the tf201 to tf201t ?

I reloaded an earlier recovery twrp 2.7.x.x and it loaded ok. Curious at this point.
[Asus  Eee Pad Transformer Prime] Bastaerd:
If you are on the stock bootloader, the recovery is the culprit, since that is the thing that changed and now it works. :highfive:

[Asus  Eee Pad Transformer Prime] AmirJamez:
can't go back to recovery mode

Hi Guys,

Just installed the newest version here and all was good.

Then i decided to reset to factory to have a fresh device and it has been stocked in the android screen. Now trying to enter recovery mode using vol_down +power or even vol_combos+power doesn't force the device to go to recovery. 5 min ago i was using that recovery to install the version. any idea?

Still I can see the device in adb devices, but adb reboot recovery doesn't work. and as well i can use adb shell ls -R / to the list of the files on the device.
[Asus  Eee Pad Transformer Prime] Bastaerd:
I did not find the time to do something due to deadlines.

Try reflashing the ROM (if you can still enter recovery after powering down)
[Asus  Eee Pad Transformer Prime] AmirJamez:
The problem os as i explained i can't go to recovery anymore!! Otherwise there was no issue at all!!
[Asus  Eee Pad Transformer Prime] Bastaerd:
Reading is hard sometimes.

Try entering fastboot mode and flash recovery by typing this: fastboot -i 0x0b05 flash staging recovery.img

Change img name to the name of the recovery you are trying to flash.
[Asus  Eee Pad Transformer Prime] AmirJamez:
ya that could work as well i suppose.

The interesting thing is that I left the tablet on while still trying to restore to factory mode and in the morning i saw it running the 5.1 screen. Strangely now I can enter recovery mode using that combo again!!!

Did you by any chance move the brightness slider past the middle of the brightness bar?

Wifi problems

I flashed this ROM with the Cyanogen recovery on the page as well as a few times with TWRP 6.3 on my TF201. It detects my wifi network on first boot but connection fails and if I click Add Network it says "Can't save network." Also the user switching doesn't work. Says, "Contact not found." I tried 2 gapps packages, gapps-5.1.x-20150404-minimal-edition-signed.zip and gapps-lp-20150222-signed.zip. I haven't found any other ROMS that successfully flash onto this device. Can anyone point me to any Lollipop ROMS that work or a more recent recovery compatible with the TF201?

Wifi doesn't work

Hi All

I'm using TWRP 2.7.0.0 and I didn't flash the recovery.img because I don't remember how to flash it. So with TWRP 2.7.0.0 I've install the cm-12.1-20150405-UNOFFICIAL-tf201.zip, it does work, but when I connect it to my wifi, it infos as "Can not connect to the network". Password is right, but just can't connect to wifi, anyone know how? I've done wipe before I install the ROM.

Just keep trying, after a few tries it should work. It is a known annoyance.

WIFI Problems

I agree keep trying. Once connected it will stay connected although after a reboot or sleep it may need to reconnect. It can be annoying, however the benefits of the ROM do make putting up with this worthwhile

Still stuck on ASUS boot logo

I fastboot flashed the new recovery in this thread, format data, wipe cache, and flashed 12.1 successfully but I also got stuck on the ASUS boot logo. I was using Cyanogen Kitkat 4.4.4 before this. I noticed people had this issue from the beginning of this thread. Was this ever resolved? I tried cm-12.1-20150405 and the latest one later in this thread cm-12.1-20150505 wiping the device clean each time.

Thank you.

Keyboard battery life and sharing

Is there any fix to allow the keyboard battery life to display, and to allow the tablet to pull power from the keyboard? Thanks.
[Asus  Eee Pad Transformer Prime] Namidairo:
See latest build.
[Asus  Eee Pad Transformer Prime] sirmatto:
No Wifi

So decided to finally upgrade from your latest 4.4.4 build. Wiped/formatted everything, got the 5.1.1 ROM and GApps pico flashed successfully. Booted up fine, everything initially seems much snappier.

The fatal flaw is that I can't get wifi to connect at all. It just says "Turning Wi-Fi on...", with no networks popping up. I might try wiping and reflashing tomorrow, but was going to leave it on tonight to see if it eventually connects. Anyone else having this problem?
[Asus  Eee Pad Transformer Prime] bnoem1:
Having the same difficulty. Am going to try downloading the zip again and reinstalling after the wipe. I know the previous mods would sometimes respond to rebooting or a new install. Good luck.
[Asus  Eee Pad Transformer Prime] Bastaerd:
WiFi turns on for me, I am typing this from my TF201.

However, connecting for the first time with an access point is a pain to do. Takes a couple (21) tries before it connects.
[Asus  Eee Pad Transformer Prime] sirmatto:
So I'm at work and can't try anything yet, but I found a useful post on Reddit. Unfortunately, my XDA account doesn't have enough posts to be able to post outside links. But if you Google "1xptm2", click the first result, then search for a comment by the OP (ryny24), where he posts two links. I think the second link might be a possible fix for our problem, essentially using an SQLLite editor to edit settings.db to change 'wifi_display_on' to have a value of '0'.

I was going to try to wipe and reinstall the latest build first. If no luck, I'll try the above fix.

I had been prepared for this WiFi connection issue, but I can't get to the point where it even lists available access points. Will post update when I get home tonight and try some solutions.
[Asus  Eee Pad Transformer Prime] sirmatto:
WiFi Not Working

No luck with wiping/reinstalling or the fixes I posted before. I unfortunately can't post a screenshot until I get to 10 posts.

I've done a little more digging. I ran an adb shell with the following:

shell@tf201:/ $ netcfg
lo UP 127.0.0.1/8 0x00000049 00:00:00:
00:00:00
dummy0 DOWN 0.0.0.0/0 0x00000082 ee:8b:79:
62:a3:51
sit0 DOWN 0.0.0.0/0 0x00000080 00:00:00:
00:00:00
ip6tnl0 DOWN 0.0.0.0/0 0x00000080 00:00:00:
00:00:00
wlan0 DOWN 0.0.0.0/0 0x00001002 00:90:4c:
11:22:33

This shows that wlan0 is down, so I ran the following:

shell@tf201:/ $ su ifconfig wlan0 up
tmp-mksh: wlan0: not found

And that's about as far as my knowledge can take me. But it appears that the wireless card is down and for some reason not able to be started. Any thoughts?

[Asus  Eee Pad Transformer Prime] bfilipowski:
It's been a while since I've pulled out my prime. This rom has gotten my interest. I've read all the posts, but am not sure how to proceed. I'm currently running the cm 11 nightly nightly from January 4th for the tf300t. How would I go about getting this room to work. I assume I'll have to revert back to a tf201t (not completely sure how) then flash new recovery from OP, then flash ROM. If anyone could point me in the right direction it would be greatly appreciated. Sorry for what I feel is a newb question I've been focusing on configuring MOAR on my s5.

Connecting with a wifi access point ;)
[Asus  Eee Pad Transformer Prime] sirmatto:
My guess is that Bastaerd is using his latest build (correct me if I'm wrong) that he created when Namidairo didn't come around these parts for awhile. I would use his build, but Namidairo's latest fixed the keyboard battery issue, which was a show stopper for me.
[Asus  Eee Pad Transformer Prime] Bastaerd:
Back to Namidairo's builds because the hdd of my build machine died :(
[Asus  Eee Pad Transformer Prime] sirmatto:
Damn. Is the "cm-12.1-20150505-UNOFFICIAL-tf201.zip" build the latest you had? CM 12.1 is so fast on the TF201, I'm willing to go forgo the keyboard battery until Namidairo swoops back out of the blue with an updated build to fix the WiFi issue :)
[Asus  Eee Pad Transformer Prime] Bastaerd:
Yup, and will be for a while because I am going on vacation to the US East Coast :)

After coming back, I'll have to wrap up a few things before setting up a new build machine and truly make a cm12.1 build. Now it's just Namidairo's repo's + cm upstream fixes. So if you did not update to Nami's last build, I highly recommend it.
[Asus  Eee Pad Transformer Prime] qubz:
Hi Guys, I'm on cm11. Will flashing the recovery for this ROM format the partitions f2fs automatically or do I have to do that manually? Also I don't have an external SD to flash this from, is it OK to flash it from internal SD?
[Asus  Eee Pad Transformer Prime] Namidairo:
You'll have to format it yourself

Also take a look at 'adb sideload', if you have a computer and usb cable available.
[Asus  Eee Pad Transformer Prime] qubz:
Thanks Namidairo. I was also thinking I'd have to side load thanks for the confirmation.
[Asus  Eee Pad Transformer Prime] sirmatto:
Never did follow up on this, but FYI, on your latest build "cm-12.1-20150505-UNOFFICIAL-tf201.zip", the wifi works fine (after trying like 20 times). I could try reflashing Namidairo's latest build "cm-12.1-20150713-UNOFFICIAL-tf201.zip" and run a logcat to try to dig more into why the wifi wasn't working in his build, but it may be a few days.

So I went to the first tf201 repository on Google with a search for "tf201 nvram_nh615.txt", downloaded file, copied it to /system/etc/, rebooted and voila! So the nvram_nh615.txt is missing from Namidairo's build. Some people's tablets seem to handle it and some don't
[Asus  Eee Pad Transformer Prime] bnoem1:
So how can we get this file and install it in our system/etc/folder? or do you recommend we wait for a newe build from Namidairo?
