That's good you managed to solve it. It's probably Cyanogenmod's Trebuchet Launcher that disallowed something like that. I'll look into Spotify, in the meantime, could you check for me whether or not this issue occurs in the stock version of Android?

Peace,

Quaesar
[Android General] Henkeman0:
Don't really know exactly how, but since my last post it has been working without FC.

I did some uninstall/reinstall of Spotify and whiped cache and so on and now it's working beautifully! So I don't think you need to look into this. It was probably just something in my device.

Thank you anyhow!

By the way, for me (with the old K100) I think CM13 would be too slow (?) so I'm hoping for future development of this 12.1 rom to get it faster and hopefully fixes for other browsers and so on. :good:

Thank you Quaesar and keep up the good work! Peace :)
[Android General] Quaesar:
That's good! CM13 will run at probably the exact same speed as CM12.1. I'm going to try making it after the Tegra 4 issue is fixed. In the meantime I'll keep fixing bugs on CM12.1. Thanks for your support!

News Updates

First of all I would like to congratulate Aaron Kling, developer BitO, and a plethora of other developers who managed to fix the issues found in Android 6.0 "Marshmallow" related to Tegra 4 devices like our Slate. For those of you who are wondering, I will be building Cyanogenmod 13.0 soon. Assuming there are no massive incompatibilities, I'm looking at a release window from Jan. 20 to the beginning of February. Of course all sources will be updated when this happens.

On another note, XDA user dvirring had a bricked Slate and asked for my help in fixing it. We managed to fix it but I realized that it wasn't clear how to recover from situations like these. On top of that, there is no "stock" ROM from HP that you can easily flash and happily go back to on your stock ways. It's also hard to find these files you need to fix the Slate. On top of this, most people's bootloaders (fastboot) are still on the old version that came with the Slate. In the coming days I'm planning on making a massive noob-friendly thread outlining topics like how to recover from a brick, restoring to stock after playing around with my ROM, updating your bootloader to the latest version, etc. As said earlier, this thread will be massive so it will take at least a couple days to make. I think when I'm compiling the CM13.0 ROM, I'll make the thread.

TWRP 2.8.7.1 for the phobos has been released! Check out my developer page on Android File Host to download it right now. I will be updating my TWRP thread or making a new one soon.

For those of you with old bootloaders (no instructions on top, tiny font size): The XDA user I mentioned earlier was bricked because of his bootloader. I'm not saying that you're screwed if you have the old bootloader (I was on the old one for a really long time too), just that updating will keep you secure from any issues that may have come from the old one. I'm also planning on including the bootloader in my ROM so that anyone who flashes will be automatically be updated.

If you have any comments, concerns, questions, feel free to ask below and I'll get to you within a day (hopefully) or as soon as I can.

Hope you guys had a Happy New Year!

Peace,

This is very exciting news! You may find that 6.0 also resolves browser issues as 5.x was rife with them on other platforms. It really would be really great if we could send you donations online. Perhaps PayPal, Square Cash, or Payza.

That's good news for all of us! I'll keep my fingers crossed that it'll automatically be fixed! I'm going to set that up soon, thanks for showing your interest! I'll be making a PayPal account so you can send all your donations there!!! You have no idea how much it makes me happy to know that people want to donate to my hard work! By the way, I'm also compiling a custom bootloader blob. I'm going to upload it soon as soon as it's fully compiled and tested!

Update 20160109!

Hey guys, I've released update 20160109. This new update features a modified bootloader I made to prevent your Slates from getting bricked. It should be quite clear when the bootloader gets installed. If (for some reason) you want to revert to the stock HP bootloader I have that on my Android File Host page. You can download it and flash using:

fastboot flash staging /path/to/bootloader.img

PLEASE DO NOT FLASH THE BOOTLOADER TO THE BOOT PARTITION. This bootloader contains fastboot while boot.img contains instructions on how to boot the current ROM - two very different things.

If anyone has any questions please let me know. As a side note, I've pretty much fixed the brightness issue. Give me a couple days to verify things and I'll post a new update. I'll also make a PayPal account within the next couple days if you wanna donate!

The link in the OP has been updated. Here is a link to the build: https://androidfilehost.com/?fid=24352994023709595

Wow! Mind blown.

I thought the newer builds of Remix only ran on Intel. I'm impressed not only do you have 5.1 running, but 5.1 with an entirely new window management system. How is it handling the 1GB of RAM in the Slate 21? From what I saw, Remix is much larger than Android as well, any problems getting the binaries all to fit? It will be excited to see how this goes. Would make for a great productivity machine.
[Android General] Quaesar:
It's handling really nicely. No lag as far as I can see. The main issue currently is Wifi and Bluetooth. Once I get those two fixed I will be going public with this build. I'm also planning on cooking up Ubuntu Touch for our device sometime in the near future. I think I should finish this first, port Marshmellow, then come back around to porting Ubuntu Touch.

On another note I've finally made myself a PayPal! You can send your donations to quaesarxda@gmail.com! Thanks for all the support guys really appreciate it. Excited to see whats coming up!

[Android General] russes82:
Have been following your thread for a little while now, thanks for the amazing work so far.

As many will agree, very excited about Remix OS coming to the Slate.

One issue I've had with CM12.1 is the performance of the Google Play Music. As soon as I try to play any song (and the album art pops up) the sound stutters and the Slate is laggy. Interesting to note this usually only occurs at the start of each song, which tells me the album art causes the playback issue. Assuming this could be a graphics driver related issue, the same issue that prevents other browsers from working? Would you expect this to be fixed with Remix OS?

Cheers,

Russell
[Android General] Quaesar:
Interesting... so only at the beginning of a song right? If the cause of the lag is proprietary graphics software then yes. The current stable build of CM runs off of ADT-1 blobs or from the Tegra Note 7 (forgot which one, doesn't matter at this point anyway). KitKat blobs are a real pain because I have to make a thousand builds fixing one issue at a time. It might take a while but will definitely fix issues.

About CM-13.0: I might hold back a bit on playing with Marshmellow until I get KK blobs booting nicely. I also figured out I need a ton of SELinux changes so that might take a while. I've also been developing for the Slate 21 Pro these days for anyone who has that device monitoring this thread. Going to make a thread about TWRP soon and a thread with CM (as soon as I get a stable, booting build obviously)

Remix OS might take a while I feel, looks like wpa_supplicant isn't on my side haha. After that who knows... Ubuntu Touch? ;)

Peace,

[Android General] charleypick:
Is it not installing? Does it respond through the CLI?
[Android General] Quaesar:
Haven't done enough testing yet. Been busy the past couple days, hopefully a solution will pop up by the weekend...
[Android General] russes82:
Yes, only seems to be an issue at the beginning. As the song progresses, the stutter eventually goes away. Then when the next song starts, more stutter.

I've also noticed recently when the Slate is asleep and I press the power button to wake it, it doesn't react. I have to power off and on to get a response.

Even more interesting...strangely enough in the past few days I installed a different browser (forgetting about the known bug) and it worked! I used Dolphin browser.

I definitely don't want to talk for all here, but I'm happy to wait and have the CM12.1 issues ironed out rather than move on to CM13.0. Although I will be greedy and say it would be awesome to have Remix 100% ported in the next month or so ;)
[Android General] Quaesar:
Yeah I'm aware of the power issue, really crossing my finger on the KK blobs to fix that. I've gotten a couple reports of Dolphin working, my guess would be that it doesn't rely on GPU rendering that much. Yeah we'll see how CM12.1 and 13 work out, kernel and SELinix changes need to be made for sure. Anything else I'll have to figure out when it gives me massive errors :p

TWRP 3.0.0-0

KitKat blobs

What a great time to be alive! Got KitKat blobs booting on CM 12.1! I'd still consider the build in a very early beta stage, here are some first impression:

- GApps is crashing like crazy and won't let me log in (maybe wrong package I'll try again)

- Lil' ol' Chrome still ain't workin'

- I had to replace hwcomposer.tegra4.so to obtain boot

- Setup was ridiculously laggy

- After (somehow) managing to reach the home screen, it had massive lag spikes for a couple minutes

- The system settled down and eventually got it's speed up to par with the current online build

- CAMERA IS WORKING!!!!!! SELFIES FOR DAYS!!!! :highfive:

- Camera light is also working

- Recent apps resolution still messed up (I'm thinking I need to make some source edits now)

- Brightness still won't change (I may have a couple tricks up my sleeve to fix this however)

I'll report any other findings I get, hopefully I can get stability by the weekend and have a new build up with full Camera support. Your donations and thanks are always appreciated! ;)

This may also solve the Google Play Music issue (just need to get Google Play Services fixed first).

Let me know if you have and comments or questions =D

[Android General] noo100:
I have a wish. The unit was formerly aligned vertically in the frame. Is it possible in one of the firmwares a third orientation to add?

e.g .:

0 degrees = normal (current Landscape screen)

90 degrees: app rotated in horizontal screen (current Portrait in Landscape screen)

270 degrees: app and screen is rotated (old Portrait method / as Smartphone) for games like Zen Pinball or Shuffle Puck

[IMG="Slate 21 Rotate"]http://i68.tinypic.com/2m4oned.jpg[/IMG]

HP meant well, but to really be able rotate the screen is sometimes desired.

(Translated by Google help. My English is not good)
[Android General] Quaesar:
Interesting to see, yeah I guess the ability to rotate could come in handy for some apps. Install the current build and make sure you flash SuperSU. Download a rotation forcer app then and see if it changes. The reason I don't want to include it in source is because some apps that work on both landscape and portrait orientations might default to portrait. That would be an annoyance to people who use the Slate with the stand and not flat down like a regular tablet.

Hope this helps, let me know if you have any other questions

Overclocking

Hey all!

Got some exciting news for everybody! I've managed to overclock our Slate from 2.2GHz to 2.55GHz! I flashed this to stock to see how capable and stable it was and wow I'm impressed! The Slate was way more snappy and responsive, things loaded almost immediately with little to no delay. I ran a HTML5 benchmark on it and it showed that the device was faster than some of the top (reasonably priced) devices out there! The kernel is also based of the latest kernel source (which I had to beg HP for) 3.4.66. The version used in the current public CM build is 3.4.35 (I think) it might fix some incompatibilities so keep your fingers crossed!

Because of how ridiculously stable and fast it is I'm planning to incorporate it into my CM 12.1 build. That should make everything a whole lot faster than it already was!

About CM 13.0, I've made a couple zips but none of them work haha. Looking at my results, I need to make a ton of kernel edits. After that, hopefully it will boot and I can debug and release something!

I'll release the OC'd kernel for stock as a flashable zip, CM will have it built in so you don't need to worry...

Let me know if you have any comments, concerns, questions, etc.

Peace,

Remix OS

Finally found out the issue that was causing Wifi and Bluetooth to not work with Remix OS! The new kernel source needs a bit more debugging to actually get Wifi and Bluetooth to work. I'll make a zip using the old kernel (used in current online build) and test it out. If all is fine then I'll create a new thread. It won't have any fancy stuff like overclocking but I can guarantee that it will work. I'll post a new build for CM and Remix when I get the new source running smooth.

Excited? ;)

[Android General] Quaesar:
For sure

Kinda forgot to post that :p. I'll make a flashable zip for it right now and start a new thread in a bit... None of my beta testers experienced their devices heating up too much but I would still recommend that you check your device isn't getting too hot when you flash it. I'd call it more of a "public beta" rather than a release since it is a pretty massive overclock (from 1.66GHz to 2.55GHz). From what I've seen it's totally worth flashing. I am also testing a OC'd version for the ranger (Slate 21 Pro)... didn't get any reports back about devices getting hot enough to fry pancakes so we should be in the green :)

Reverting is easy... flash this within my TWRP: https://www.androidfilehost.com/?fid=24367857647223248

Please note it will replace your recovery to stock to so you'll have to flash TWRP again if you want. This version of stock is HP's 10.10. The latest is 11.11, I found the OTA file for that and am gonna make a flashable version of that soon (one that doesn't replace your recovery lol ;) )

After some testing, I've finally decided that this overclock is stable enough to be your daily driver! I've created a new thread which has download and install instructions on it. The kernel is very stable and I have never seen it crash. CPU temps are not higher either so we should be in business!

[MENTION=6847973]Quaesar[/MENTION], I didn't know where to post this question and I know that you are pretty good with roms. Do you know a way to make the status bar transparent in stock 4.4.2 slate 21?

Is there something i can download or change something in builtprop to make the status bar and nav bar transparent?
[Android General] Quaesar:
Sorry I honestly don't know, you could try posting in the general Q & A section of XDA and I'm sure someone will be able to help you out there. I pretty much only use my Slate for developing and would have normally recommended Xposed. Not sure what else there is out there. I'm certain that there's nothing in build.prop with that sort of option. Build.prop just stores device specific info.

Earphones dont work

[MENTION=6847973]Quaesar[/MENTION], I tried your cm12.1 rom but because of the little issues like stock browser, and brightness, so I reverted back with your stock 4.4.2 file and flashed your oc kernel. Everything is running good except the earphones are not working anymore. I know for sure that they where working with cm12.1, but now when I connect my earphones to my slate the sound keeps coming from the speakers and nothing comes out of the earphones. Do you think it could be a hardware problem or maybe either the your stock 4.4.2 file or the oc kernel?
[Android General] Quaesar:
I'll look into it, I'm not sure if kernel has to do anything about that... Just been ridiculously busy these days, can you report to me the results of these tests?

1. Is audio working in the latest CM12.1 build?

2. Is audio working on stock 4.4.2 without the kernel?

3. After flashing the kernel again, do you lose audio?

I did the tests you wanted.

I really don't know what caused the earphones not working before, maybe I messed up something in rom. But everything is working great now. Thanks
