Hello everyone! Thannk you Quaesar you are awesome!

Hi My name is Clancey Aggen, I own 3 of the Hp 21 k100 Slates. one is the Ginny pig, I have just finished reading this thread and are up to date I only understand so much, but I'll take what I can get, and question otherwise, It has been a challenge for me getting my Slate to where it is now, I'm still using 4.4.2 Kit cat. I have made a backup. I think my next step is to update TWRP to a newer version, I'm on v2.8.1.0, do I need to remove the app or just install over it? and will i lose my backup? I'm all for running CM 12.1 as most of the bugs wont effect me I only hope that the one app I use works.

Would it be better to keep with 4.4.2 with newer kernel? and should I wait for CM 12.1 bug fixes? before switching?

I'm really interested in overclocking because this thing lacks preference.

Hope this helps you help Clancey aggen Thank you so much and keep up the good work Quaesar :good:

:o

Okay I figured it out, I now have the latest version of TWRP 3.0.0-0!

Now I want to install the kernel.

Okay I went ahead and flashed the kernel with success, is there an app required to do the overclocking or is it already done?
[Android General] Quaesar:
68*C is fairly normal. If your device temp was above 93*C then I'd be concerned. Processors naturally create a ton of heat, 68 is pretty low for an overclocked device. The reason we don't want it getting hotter than ~93*C is because we don't want the solder inside the device to melt lol. This overclock is pretty safe though so you shouldn't need to worry about that.

I still am developing, just a bit busy with life here and there but expect a CM12.1 release soon with the updated kernel.

To answer your questions:

- You will need my latest 3.0.0-0 recovery for this device (see the OP for a link)

- Backup within the new TWRP before performing any modifications

- Whether or not you want to wait for the fixes is completely up to you. I'd suggest that you try CM and if the bugs bother you switch back to 4.4.2.

- You don't need to install an app after flashing the overclocked zip. You should see my custom bootanimation, you'll know you have installed it correctly when you see that

- You can install an app if you want to manually control clock speeds

- Just remember not to flash the OC'd kernel overtop of CM, it's not compatible!

To all monitoring this thread: Sorry for the radio silence, just getting overloaded with work right now. Once things calm down a little I'll return to fixing issues, eventually CM13.0

Let me know if you guys need anything else, glad to help.

Peace,

Quaesar

Peace,

Quaesar[/QUOTE]

-I do see your custom boot animation.

-I do have the latest 3.0.0-0 recovery

-Do i need to change the kernel that I installed to overclock 4.4.2 ""OC'd"" before I install CM? I did read that CM comes with the overclock pre installed I just want to be sure.

Thanks hope this helps you help Clancey Aggen:)

[Android General] evildog1:
Hi,

Does it enable full 4 cores when the tablet is getting slow? or just always 1 core like the original OS and kernel?
[Android General] Quaesar:
Alrighty, watched your video and see what you mean. Here are my theories:

- Audio drivers are proprietary on the Slate, I might have to try a couple devices with similar board that natively run 5.1.1 and steal some blobs from there.

- The hardware DRM component is not functioning as expected. Probably have to switch another set of blobs

- GPU cannot be accessed correctly. This puts strain on the main CPU for processing artwork (another user noted this). This should be fixed alongside Chrome issues hopefully

- Any combination of the above statements. That would really suck though because it'll take longer to solve. Eventually I will finish this and make it stable though.

Also, CM12.1 is not overclocked. The kernel in CM is the old one. Unfortunately there are Wifi and Bluetooth issues I need to solve before I can release an overclocked CM12.1 version. Wifi and BT are a major pain in the *butt*. Takes forever to fix them but once I do, baby we are in business. New CM release will also be using native KitKat blobs so expect a lot of issues to be automatically fixed (I can take selfies now hint hint nudge nudge)

I don't believe so. I only saw one live core in Kernel Auditor. If it's possible I will enable all four cores.

Peace,

Quaesar
[Android General] evildog1:
Damn HP... when i try to enable more cores, it just disable it again. it does not have an option to disable hotplug or something...
[Android General] Quaesar:
Sorry for the late reply, kinda saw this a while ago and forgot to reply completely lol. I'd recommend you take a look at my kernel source on GitHub. Use the cm-12.1_oc branch to compile. Try to search around for other devices that may have had a similar issue and apply fixes from those. Let me know if you find anythig but don't know how to implement the fix, I can test it out.

Q
[Android General] UAS specialist:
Anything new? I'm experiencing instant crash reboots with cm 12 And the weird thing is that I'm not 100% sure but I think it's only happening to this slate, and not my another one, This Rom really speeds things up but have experienced many things not working thus so far.
[Android General] Quaesar:
Almost there! Turns out my source got corrupted so I'll have to remake a bunch of stuff. Easily doable, it'll just take a bit more time :p

Keep those fingers crossed!

Q
[Android General] mpbretl:
Is there a workaround for the "power issue"? I installed this ROM on the Slate 21 in my kitchen, and now it won't last a single day without having to power cycle it. I'll probably need to revert to stock.. what's the easiest way to do that?

EDIT: Nevermind, I found evilp's stock ROM in this thread: http://xdaforums.com/showthread.php?t=2568407&page=18 Flashed it in TWRP, and now I'm back in business. Thanks for all the hard work guys.
[Android General] Quaesar:
What I usually do is turn off the sleep. That makes it not do weird glitches. Might be a bit of a power hog that way, but I only turn it on when it's in use or I'm devving. Hopefully the new release (with KK blobs) will fix this (coming soon, stay tuned).

EDIT: Looks like those sneaky TWRP devs released 3.0.2 and I didn't catch wind of it. I'll upload a updated TWRP this weekend.
[Android General] UAS specialist:
Is there, And i may have already asked this, But a way to overclock the stock jellybean rom?
[Android General] Quaesar:
Stock Jellybean? No lol. I haven't looked into the old kernel. I've been trying to move my projects from the old kernel to the new kernel. That's why Wifi and BT fixes are taking so freaking long lol. From what I know, there isn't many people interested in JB compared to KK. If there's demand for it, I'll certainly make it. It's just that I'm preoccupied trying to fix BT and Wifi for the next CM release.

I'm really hoping for some more donations to come in, I know the project's been dead for the past month but now that I'm back in, I hope there's still as much demand as before. The thing that's taking so long with this release is that I've completely changed source. There's barely any files that haven't changed haha. Apart from the massive overhaul to the code, all the proprietary blobs are new, that took around a month and a half to debug.

Anywho, it's just a matter of time before I destroy the remaining bugs. Maybe after that, I'll fix up REMIX and start again on CM13.0 (as phobos projects).

Hope that answers your questions,

Q

EDIT: Looks like this new build I made fixes deep-sleep (long period of time in sleep) issues. I've had it in sleep for about an hour and turned on immediately. I'll hold an overnight test soon.
[Android General] Quaesar:
Status Update

Aaaaaaaand success!

I'm running CM12.1 with new blobs (camera is working!!!!). I'm going to continue using the old kernel for now until I figure out what's causing the issue with Wifi and BT. The only thing not working now is Google Play (which is a critical thing). I'm going replace some blobs over this and next weekend to see what can alleviate the issue. If this rate of development continues, you guys should get a release by May long weekend!

Let me know if you have any questions,

[Android General] Quaesar:
Wifi issues on that too =/

[MENTION=6847973]Quaesar[/MENTION] Hey So your familiar with modding kernels right? I Could really use your help or maybe you can point me in the right direction. I'm trying to basically make my own 21" android tablet with hardware that is readily available, I have my touchscreen panel and its controller, and android driver, But have no idea how to install the driver tech support says To install EETI Android driver.

Needs root permission and rebuild the kernel source code.

This is what I'm thinking of getting.

Also what sets apart the USB ports on the HP 21 slate K100 2 in back vs 1 on the left side, I know USB thumb drives do not work for me on the side USB port, It's like there is no power coming from it. Also when I use the male to male USB cable coming from my Drones remote controller it only works in the side USB port with USB Debugging enabled, I need to know it will also work with this new android box how can I guarantee my device will work with the new android box. specs don't tell me much sorry for this long message :)

Looked around a year ago, and there was nothing for the Slate 21 Pro (ranger); however, I see this thread which appears to be for the earlier versions of this Android Slab. (phobos) I predominately use it as a touch screen monitor for my PC (got it at a good price); however occasionally use the android OS and would like to upgrade, if possible to Lollipop 5.x.

Q, Is this compatible with the Pro version? It is still running Jelly Bean 4.3 and have not upgraded to the 4.4.2 KitKat as I have read bad reviews on the update.
[Android General] Quaesar:
This is not compatible with the Pro version. However the devices are extremely similar. I have a couple major bugs to sort out before the release of an update for the phobos and the first release for ranger. Trying to get into touch with a Linux dev to see if he can give me a hand. Be patient, this is really tough work!

Hi [MENTION=6847973]Quaesar[/MENTION], just wondering if there's any updates on progress with dev on CM12.1? If you need any UAT done please let us know :)
[Android General] Quaesar:
Thanks for the offer man! Unfortunately that's not the thing I need. Contacted a few other debts and they all say that this sh*t is weird. I test ideas whenever I get them but I haven't even had a minor success yet *sigh*. Thanks for the support though guys! If anyone knows a dev (a kernel dev even better) that could help please let me know somehow. I hate to disappoint and be slow but these issues are real pains in the rear end =P

Thanks guys!

[Android General] druidt:
Is it going to be possible?

I use mine only as my piano music sheet display - it's very good for that!

Basically I use the launcher, XODO and Screen Filter

the problem is with the limited memory the Screen Filter gets unloaded (or stopped) and the screen becomes too bright!

(less often I use Adaptive Rotation Lock with the piano interface app)

I should try to find a lighter launcher...

Netflix not working

Hi Quaesar and thank you very much for your development on HP Slate 21.

My five year old daughter and me are really enjoying your ROM build.

However, there is a problem with Netflix: it crashes instantly, can't even open.

Any advice about this?

Thanks.

Cheers!

---------- I WANTED TO MAKE TWO POSTS ABOUT TWO DIFFERENT SUBJECTS BUT FORUM SOFTWARE AUTOMATICALLY MERGED MY POSTS ----------

Hi Quaesar and thank you very much for your development on HP Slate 21.

My five year old daughter and me are really enjoying your ROM build.

However, there is a problem with some portrait mode games (like Monument Valley):

- if we don't use any extra software, the game goes portrait and it displays properly, but, as expected, the screen is rotated 90 degrees and we can't really rotate Slate as we could some other tablet or phone - unusable

- if we use 'Ultimate Rotation Control' to force landscape, then, indeed the game is shown in landscape mode and no rotation occurs, but, the game doesn't get the proper screen resolution numbers and the display is actually cropped, i.e. you can't see the top and the bottom of the game, hence you can't play it, as it doesn't use scrolling when the screen is full - unusable

Back in the stock HP days, there was this program HP Portrait or HP Rotate or something similar (can't remember the exact program name now) that was fixing this problem correctly. The point here is that you can't just force landscape screen mode - you need to also somehow fake the resolution. So, old stock HP software was doing this by setting the screen height to 1080, but then faking screen width to 608. That way, portrait apps were displayed with black bars on left and right side, but one could see the whole app display.

Right now, when we force landscape mode with 'Ultimate Rotation Control' the screen is full, there are no black bars, but top and bottom are cropped (out of view) and hence one can't tap on menu buttons or in-game areas or whatever.

I wonder how Android TV fixes this problem.

Any advice about this?

Thanks.

Cheers!
[Android General] evildog1:
any new updates? i'm waiting for working Chrome browsers
[Android General] Quaesar:
I don't see any reason why not :) I'll get to it in a couple months, life too busy right now with other stuff.

[MENTION=427967]AtmanActive[/MENTION]:

Netflix doesn't work because of a hardware DRM component that glitches, on my to-do list now I forgot about that. About the rotation, it's kinda weird that the app you're talking about showed up like that but I get what you mean. I wonder if installing the APK for that HP Portrait app will fix this, if you have time perhaps extract it from the original ROM and install on CM to see what happens.

[MENTION=4623971]evildog1[/MENTION]:

Soon my friend

Everyone: I'm heavily considering bailing on CM13.0 and going straight for CM14.0. The CM13.0 ROM has never booted because of those gosh darn kernel issues, I'll cross my fingers that CM14.0 somehow changes that. As for CM14.0 on Tegra4 devices in general. I talked to some of the other devs and they've only been able to get to the boot ani. Surfaceflinger is to blame here, hopefully we'll get a patch for that soon too. I'll also take another shot at Wifi and BT on the new kernel (I'm sounding like a broken record now).

As always, thanks for the support and continued patience. I know it's getting close to a year since the last major update but I really want to deliver something solid and stable and I know this will take some time. I will keep you all posted on my findings and whatnot.

Peace,

Quaesar

EDIT: I'm not sure if I've said this but camera works perfectly now, the next release will let you Skype all you want.
[Android General] evildog1:
[MENTION=6847973]Quaesar[/MENTION] you should also work with Remix OS ROM because it would be easier to use for my mom. she still getting confused with Android GUI.

Hi,

On the third party browser issues. I have tried a few and firefox appears to work now!

I have an odd issue where my Slate 21 won't turn on after sleeping for long periods and I have to pull the power. I think this may have been a problem that many slate 21 owners had with the stock ROM, I just wondered if anyone had a fix?

Thanks

Michael
[Android General] cliq:
hello guys, can this fully work on HP Pro Slate 12 and is this without bugs?
[Android General] Quaesar:
Yeah will do, I'm gonna start devving around February, life is too busy right now haha.

[MENTION=563211]michaelsage[/MENTION], I'm willing to but money at this point that Firefox works because of no GPU requirement ;)

[MENTION=416255]cliq[/MENTION], The bugs listed are the major ones. There might be some tiny ones but if you're okay with the major ones listed you should be fine. The OS itself is very stable. If not just wait some time for the next release (I know it's been a while bear with me).

You have to use an external SD Card (full size). USBs will not work.

Only the original. The next release (fingers crossed no more problems) will be out at the end of this month. I will release a phobos and a ranger together so we can have double the fun. :p This will be the final version of CM12.1 I will make. All newer releases will be Nougat as I don't want to spend an insane amount of time debugging Marshmallow when we can get the latest and greatest.

I appreciate everyone's patience so far as this hasn't been easy on me. As they say, the fruit of patience is much sweeter.

Various fix for cm12

.............................................................................

See post #175
[Android General] :
So now brightenes is fixed (bug caused by /system/bin/powerservice not present), google chrome and netflix fixed; we have only to fix the camera and tweak a little the ROM, right [MENTION=6847973]Quaesar[/MENTION] ?
[Android General] :
FLASHABLE FIX FOR:

-brighteness

-chrome and netflix

-Low ram mode: no lock-screen wallpaper, no recent app preview of app, improved stability

-bigger UI for fix various graphics bugs, more tabletish ui

-various build.prop tweaks

.....................................................................................................

WHAT YOU HAVE TO DO

-download zip from HERE

-install it from TWRP

................................................................................................

HOW TO CHANGE BRIGHTENESS

-open Rootdim app (included in the zip)

-change it thougt app
[Android General] druidt:
Installed it yesterday - looks good - thank you! :good:

I didn't like the bigger UI ... I changed the DPI to 200 - can we go lower than that?

(I use the slate only to display PDFs for my piano music, this means my testing is very limited...)
[Android General] :
Yes there is no problem to go lower than 180-160
[Android General] russes82:
Thanks for the update Fernando, however after I flashed the update via TWRP to noticed there's now a red bar at the top and bottom of my Slate, and Rootdim doesn't seem to work as expected (opens with blank screen). Have you experienced this?

EDIT: I reflashed the ROM, SuperSU and your update and all is fixed. Update seems to be working a treat, as is Rootdim
[Android General] evildog1:
What SuperSU are you using?

Mine bricks when i flash SuperSu 2.8.2.
[Android General] russes82:
I'm actually using SuperSU 2.8.2 as well but had no issues with bricking.

Sadly the only thing I can suggest is to reflash the ROM. Maybe also check the SD card is working as expected, I've had issues in the past flashing files (not with the Slate 21) where the microSD/SD card had write errors.

Otherwise @Quaesar, is this something you can help with?
