Did you try the Dirty Unicorn 4G Kerne that I posted here?

DU 4G Kernel

I can not post Kernel for models that I can not test and verify that it works.

If you are willing to test and verify, then I can make all the changes to the 4g Kernel to have it work as the WiFi.
[TouchPad General] BGrosse:
HP_TOUCHPAD:

In general I am willing to test everything, especially because I have all models here on my hands. And to be honest: I did not test the 4G kernel you linked there as of now because all DU's wifi ROMs I tested I have found to be not a daily driver due to random reboots here and there and also spontaneous rise in current drains up to 200mA and more every here and then for no reason. They simply haven't reached the stability and mature level of EVs 7.1.2 ROMs.

But if you are able to build new Oreo or Pie ROMs and kernels regardless of wifi or 4G which will bring us more stability I will be glad and happy to be the first one to test it! :highfive::cool:

Edit:

Just to clarify my testing as of now:

1.) EV 7.1.2 Wifi ROM traditional setup with SKZ kernel: laggy every here and then, but stable

2.) EV 7.1.2 4G ROM traditional setup with SKZ kernel: laggy every here and then, but stable (eventually little bit faster than the wifi unit above)

3.) EV 7.1.2 Wifi ROM new partitioning setup with SKZ kernel: stable, smooth and funny to use for everyday. My favourite now! :D

4.) EV 7.1.2 4G ROM new partitioning setup with SKZ kernel: pending (got a kernel from shumash for this, should be tested next)

5.) DU 8.1 Wifi ROM traditional setup with SKZ kernel: sometimes laggy, random reboots, not stable

6.) DU 8.1. 4G ROM traditional setup: not yet tested

7.) DU 8.1 Wifi ROM new partitioning setup with SKZ kernel: still laggy sometimes, less reboots, but not as stable as 3.)

8.) DU 8.1. 4G ROM new paritioning setup: not yet tested

Additionally I grabbed a Sierra Wireless 7710 card as to your linked posts to make sure I get the most out of my 4G Touchpads. Just have to open one for the next step... :fingers-crossed:
[TouchPad General] HP_TOUCHPAD:
I do not built ROMS or Kernels, I can only apply changes to the provided Kernel and ROM from the last and current version of Android. 7.1.2, 8.1 and 9.

Stability is an impossible goal to reach, not all the HP Touchpad were build from the same hardware supplier. The inner working are different and does not behave the same, an issue may not be ROM related but the hardware. All users use the Tablet differently with different apps which may cause issues that can be software and not due to the ROM or Hardware. The individual user is the only one that can trouble shoot it's own Tablet to find out what could it be, it gets complicated.

We are all using BETA OS software nowadays, Desktop or Mobile. Everything is been updated constantly to fix issues.
[TouchPad General] BGrosse:
Hmmm... I tested DU's 8.1 ROMs since last year and on 2 different Touchpads (wifi of course). On both machines I had the same software setup incl. all Android settings (just a handful of apps, not heavily loaded - really!). And on both machines I have had the spontaneous reboots, not only on charger. Just when it lies next to me at some time it reboots. No touch, no action, no charging - just rebooting. And the rise of the current drain sometimes also shows that something is going on inside which prevents the device to sleep and keep calm. That was the point for me to better stay with the EV 7.1.2 ROMs. Of course they are also not perfect but really really better in terms of stability. At least in all the tests I did for monthes now. I edited my last post - please read. The problem for me is to get into it and find the root cause of these problems. At least I am not such familiar with Linux as of now. Maybe we can change this... :)
[TouchPad General] HP_TOUCHPAD:
My advice on how to test a new ROM (This also applies to any OS Desktop or Mobile)

((Prepare the media first)) Storage (hard drive)

Using TWRP Recovery wipe all the partitions.

Format Data

(( Reboot ))

Check File system for errors using TWRP Recovery:

Wipe --->>> Advanced Wipe

Select one partition at a time

Repair or change File System --->>> Repair File System

( If errors ) then select Resize File System

Then Repair File System again.

When there is no errors in the partitions allowed to repair.

(( Reboot ))

Install the New ROM ( As the developer intended ) nothing else.

Use the ROM as is Do not install any apps.

Test the ROM for a week, with WiFi.

Charge it and drain it.

Keep it on for one week.

Keep some apps open to monitor it for any reboots.

If after one week of been ON and there is no issue then you know the ROM and Hardware are working.

Install Skz Kernel and apps.

If you want to isolate a problem then install one app at a time.

It only takes one app to break everything.

I have tested 7.1.2 and 8.1 and both are stable. I have not experience any reboots. I use both set on 1836 Performance settings and take it to the Max.

But I do not have it loaded with many apps than could be creating many task in the background.
[TouchPad General] BGrosse:
Hi [MENTION=1009123]shumash[/MENTION]!

Just wiped one 4G TP completely with the "Wipe_All_and_Create_Android_with_Swap_Partition.zip", so started from scratch and installed the latest 4G ROM, opengapps pico, keyboard and finally the kernel you linked to above.

Unfortunately the TP does not boot at all. Splash screen of your kernel ist displayed, but the EVERVOLV logo does not come up. Just blank screen and after a minute or so the TP simply reboots. To what clock did you set the kernel above? Maybe 1892 is too fast for starting up although it has worked when in Android and set with KA within Android at the last installation. Anyway... any ideas? :confused:

---------- Post added at 08:10 PM ---------- Previous post was at 07:54 PM ----------

Hmm... speechless... Checking for file system errors I didn't ever have done this because - especially when I'm about to test something new - I always start from scratch meaning I always wipe everything completely. So no errors should have taken place.

As for testing the DU ROM without any app installed I have to repeat this with a new installation. Except the install of any apps, what you suggested is exactly what I am doing with any new installation. Just install the ROM, let it settle for some hours, turn wifi on with my google account and keep it ON (sleeping of course). After I found everything is working, I started installing a handfull of apps, configured them (i.e. ES File Explorer and 3C Toolbox) and played around with it for some days.

But I will try it again without any apps. :fingers-crossed:

In the meanwhile I am trying to get the EV 7.1.2 4G running on my 4G TP with the kernel shumash offered. But to no avail in the first shoot. Hopefully we get it managed soon! :)
[TouchPad General] HP_TOUCHPAD:
Extract the boot.img from the EV 7.1.2 4G ROM zip file.

Rename it to uImage.Evervolv_4G_original and copy it to the boot partition using TWRP Recovery File manager.

On the boot menu you will have two boot images (Kernel) to choose from, that will help identify if it is the Kernel or File System.
[TouchPad General] BGrosse:
Ohh... good idea. Thanks! :highfive:

But using the "old" original kernel - what happens to the new swap partitioning setup? Does it simply make no difference to the "old" kind of setup? Can we simply move foreward and backward to "old" and "new" kind of swap setup when switching between kernels? My understandig of your new setup was: If we decide to setup the new swap partition, we have to use the new SKZ kernels from shumash and never use the original ones. Is it a misunderstandig from my side?

Trying the original kernel now... At least it boots up... Seems to work :fingers-crossed:

OK, booted correctly and is setup'ed now. So it seems the problem is the kernel. Anything else I can do to debug?
[TouchPad General] HP_TOUCHPAD:
The issue could be in the Kernel or any setting in the Ramdisk.

Your system is working properly, the only thing to do is to flash different kernels builds and see which one boots.

I will upload a version later, will post the link.

In the meantime you can flash Dirty Unicorns 8.1 and flash the 4G Kernel that I posted, if it works then it will help on creating the 4G 7.1.2 version.
[TouchPad General] BGrosse:
OK... thanks in advance! Shumash just compiled this one and posted it here - he already told us that he don't know if it even boots. Normally all his kernels have worked fine so far - don't know what's wrong this time.

Thanks also for the hint to wipe cache and dalvik between different kernel flashes. Until know I never cleared the caches when flashing Shumash kernels as he told us at one time that it is not needed. But now we have different kernels here, so clearing caches makes sense. Got it! :good:

---------- Post added at 10:58 PM ---------- Previous post was at 10:53 PM ----------

Will do it asap. Just need a nap now. It's already late. Will be the first thing to try during breakfast. Will keep you informed! :highfive:
[TouchPad General] HP_TOUCHPAD:
This Skz kernel is not optimized in any way, but to test if the 4G modem can work with it. If the modem does work then the settings for optimization can be apply.

The Kernel does boot in a regular WiFi model and it should also boot in the 4G model. The attached screenshot is from this kernel.

[TouchPad General] BGrosse:
OK, back to the test bench... Sorry for being a bit late, but got a new smartwatch to play with... :cool:

YOUR KERNEL WORKS GREAT!!! Good work, no reboots, smooth to use, just used 4G network only since now (no wifi setup'ed, no google account registered yet) although gapps pico was installed. What kind of optimization you would apply now? Let me know if I can test anything for you! :highfive:

P.S.: Do you have an idea how to find out which modem card is installed (Ericson or Sierra) in my 4G? I tried lspci from the command line to no avail and searched the play store for some apps to find out more about the hardware/vendor, but to no avail...
[TouchPad General] HP_TOUCHPAD:
By the Kernel module or driver the 4G card is a Sierra as I posted on the Dirty Unicorns version. Can you please test the 4G Kernel that I posted for Dirty Unicorns?

If that works then Dirty Unicorns 8.1 and Pie (9) will be able to use the 4G modem.
[TouchPad General] BGrosse:
Of course, no problem. Just to clarify: as the swap partitioning already exists I just wipe every partition competely and install the latest DU ROM together with your 4G kernel? Or do you have any other suggestions?
[TouchPad General] BGrosse:
Of course...
[TouchPad General] HP_TOUCHPAD:
Once the Tablet has been partitioned as posted on this guide is set for ever and any ROM, it works for Pie and Q all the way to Android Z !

Every time you will install a new ROM my advice is to wipe everything and format DATA, obviously you will back up all your data to the PC first.

You mentioned that you can use your 4G model up to 1892. I can set up your own personal setting to run at 1836 Performance, that will be stable and give you the Max performance with no reboot. Please confirm that your Tablet can handle that speed and maintaining it.

Thanks for the screenshots ! Verified ! I will post all the optimized Kernels for Evervolv 4G 7.1.2
[TouchPad General] BGrosse:
Hmmm... at least with the last 7.1.2 installed "old" EV build with old partitioning it has run with 1836 (set with kernel adiutor). Maybe you can generate 3 kernels like shumash did for 1725, 1792 and 1836. Especially because I will be not the only one with a 4G out here and not every tab can handle 1836 even if mine can do it. What do you think?
[TouchPad General] HP_TOUCHPAD:
The 3 different variation of CPU speed are mine optimized settings from the Skz kernel provided by Shumash. I did those separately so that the user did not need to install any Kernel app in Android. I will generate the 3 speeds as I did with all the WiFi versions, but is the same Kernel. The changes are only apply in the Ramdisk.

Once you have successfully tested the 1836 in Performance mode anything else will work for all Tablets.
[TouchPad General] BGrosse:
OK, should I wait for the 4G 1836 7.1.2 EV kernel or should I destroy this test bench and setup a DU 4G build for testing further?
[TouchPad General] HP_TOUCHPAD:
The settings that I will make to EV 7.1.2 will not affect the 4G modem and you all ready confirm that it works, testing is done.

Try the DU 4G, it will be very interesting to know the results!
[TouchPad General] Steelskinz:
Thanks all for your reply. I will wait until a Pi compatible kernel with swap partition is released. :)
[TouchPad General] BGrosse:
OK, up and running a DU ROM now with wifi SKZ kernel 1836 on the new swap system. Runs fine on a 4G machine with gapps pico. Let it settled down and installed your 4G DU test kernel. Runs also fine but no mobile data support. As per your advice installing gapps full now. Press thumbs! :fingers-crossed:

---------- Post added at 07:21 PM ---------- Previous post was at 06:58 PM ----------

edit:

Installing gapps full does not change anything except we get additional AOSP keyboard FCs. Repeatingly. See pics.

No mobile service, no status in settings-about. It's like having a wifi kernel / ROM only. Also there is no ROM toolkit. Maybe we need that first... :confused:
[TouchPad General] HP_TOUCHPAD:
Thanks for testing, I was looking in detail last night into the Ramdisk of 4G and WiFi and there are differences with modem settings. I will incorporate those settings into DU 8.1 and will post another version for DU 4G. If it does not work with that then it will take an expert to get all the requirements settings for a 4G mode.

Do not trash DU yet, I will post another kernel.
[TouchPad General] BGrosse:
No, I will keep it for further testing - at least for the next days or weeks it it's necessary. But when it does not come up - what can we do? The expert which is closest to this is [MENTION=3716175]flintman[/MENTION] afaik. But he already left the ship... :eek:
[TouchPad General] HP_TOUCHPAD:
Flintman did not left the ship he, under the Dirty Unicorns Team just provided Android 9 Pie. Is impossible for developers to work on a device that they can not test. Is like working in a dark room, you can not see what you are doing. To get Android working on Tablet is a collective team work of a "LOT" of developers and one depends on the others to accomplish tasks, and all of it is voluntary work when they have the time to devote to it.

Attached is the fixes on the Ramdisk and also the Tool Kit. If it does not work with this, there is not much I can do. It will be a miracle if it does!

[TouchPad General] shumash:
DU is dead, as they posted on their site. The RC, and all other DU Pie releases are the last ones, at least as DU. If flintman continues to work on the HPTP, it will be on his own or with some other team.
[TouchPad General] BGrosse:
Yeah, that's what I meant. As of my humble knowledge, DU stopped working on the HPTP - therefore I was very surprised that last week there was a Pie release posted. But OK, this may be the one which [MENTION=3716175]flintman[/MENTION] had already running last year (his first shot).

[MENTION=1009123]shumash[/MENTION]: are you able to help us out with getting 4G on the DU ROM? I will test [MENTION=8005714]HP_TOUCHPAD[/MENTION]s 4G V2 kernel todays evening, but as he already said, it must be a miracle if it works. Or do you have contact to [MENTION=3716175]flintman[/MENTION]?
[TouchPad General] HP_TOUCHPAD:
It has been a very interesting journey since HP introduced and terminated WebOS and the HP Touchpad in 2011. Nobody imagined back then that a massive blood kill of WebOS and the fire sale of the HPTP will extend the support of the Tablet into the year 2019 and will easily make it to 2020!

As history has showed companies got dissolved or transfer over but the code still is alive and better than before.

From Palm to HP to the current WebOS owner LG and the introduction of a new webOS phone : The New Palm phone is revealed.

In reality WebOS never died, but reincarnated into TVs made by LG.

WebOS for the HP Touchpad is LuneOS and the latest build is Doppio : LuneOS for the HP Touchpad

The same happened to the Android custom ROM teams:

From Cyanogenmods to Lineageos LineageOS

This is how Dirty Unicorns came to be : The birth of Dirty Unicorns Click here for the story

As posted on the Dirty Unicorns web site "

Our Github organization will stay up as a reference for any developers that would like to carry on a similar project and/or port any of our work forward to future versions.

"

Everything is a cycle than needs a fresh start, that applies to peoples life and their projects.

As posted on the Dirty Unicorns Discordapp ( last Friday at 5:22 pm by Flintman )

Developers are the backbone of a company, not a logo or a catchy name.

Pie is stable as is using the same Kernel and improved. The question is [MENTION=1009123]shumash[/MENTION]: Will there be a Pie version of the Skz Kernel?
[TouchPad General] HP_TOUCHPAD:
[MENTION=1009123]shumash[/MENTION]: are you able to help us out with getting 4G on the DU ROM? I will test [MENTION=8005714]HP_TOUCHPAD[/MENTION]s 4G V2 kernel todays evening, but as he already said, it must be a miracle if it works. Or do you have contact to [MENTION=3716175]flintman[/MENTION]?[/QUOTE]

@BGrosse for any developer to be able to provide support for the 4G model the developer has to have the device on hand (owned it). Is the only way to work on it and troubleshoot it. I am sure Flintman would have provided support for the 4G if he had one.

OK, of course I understand this. I did not realize that flintman has no 4G pad when Evervolvs 4G ROM have been released. I would be happy to spend one if we can get Oreo or Pie to work with mobile data :highfive:
[TouchPad General] HP_TOUCHPAD:
You can contact the developer directly and offer to donate as a gift a 4G model to try to get it working with the new ROMS. I did that myself and sent a tablet to shumash while we were improving the frequency and voltage of the Tablet. This is all voluntary work and no developer must do, is just willing to help.

If you would like to contact Flintman directly he is on-line now in Discordapp.com under Dirty Unicorns.

To get there just go to the Dirty Unicorns web site, and read first page click on Discord server, create an account and you can chat there.
[TouchPad General] BGrosse:
OK... Done. Had a nice talk with Will... again :D

We simply have to wait. I think there will be no 4G ROM for Oreo, but there are chances to get one for 4G once testing the first P builds are finished and positive and Will got some time for it. At least he HAS a 4G pad! :fingers-crossed:
[TouchPad General] BGrosse:
OK... does not work either. No visible change to the first 4G kernel. No SIM toolkit, no status in settings menu, no mobile data anywhere. :(
[TouchPad General] HP_TOUCHPAD:
Thanks for trying, is the best I can do.

Per my chat with Flintman he needs to rewrite the RIL and also packages that need it to be ported.

Now you know what it will take and who can do it. In the mean time use it with Evervolv 7.1.2 is a solid good ROM.

Until Pie is fix and the 4G model added.
[TouchPad General] raimerik:
Hi [MENTION=8005714]HP_TOUCHPAD[/MENTION] !

Cheers for this step-by-step and all the useful enhancements!

I'm really looking forward to testing all this.

One question: In your first post you talk about setting the partition to 1400MB ("But to use Dirty Unicorns and Evervolv the Android /system partition must be 1400 MB") only to report a little later: "System 1.8 GB ( Android Operating System ) 1.8 GB allows to install The Super Variant of Open Gapps and it works well."

So what is the recommendation? 1400 for pico and 1800 for everything else? Cheers for clarification!

And any chance to get a step-by-step of resetting a HPTP and setting it up with Android + webOS + luneOS (+ possibly SailFish)?

That would be really interesting!

Cheers for all your work! raimerik
[TouchPad General] HP_TOUCHPAD:
You are welcome, have fun with your Tablet and learn and keep in mind anything you do to it, it will not brick it!
[TouchPad General] raimerik:
Oh, I will... ;)

I just figured out that my 16GB TP is a Android-Only. :(

Which guide would you recommend to restore it to webOS before starting with this guide of yours here?

(Sorry for pestering and a) big cheers! raimerik
[TouchPad General] HP_TOUCHPAD:
If the only thing you want to do is install all the different Operating system on the Tablet and not use it for apps or data then the 16G will provide all the space need it to play with.

This is how to do it, quick and easy, keeping in mind you know how to do all this already. All this steps have been explain on XDA since 2011 you will search and find the threads dedicated to each process.

1. Use the ToolBox:

Wipe all , data reset.

Create WebOS volumes (partitions)

It creates the /dev/store/swap (partition) to be use by WebOS and can be share by Android

2. Using the ToolBox, create Android partitions and create /system to be 1400mb or higher not need to be more then 2G.

3. Install WebOS if you know your way around Install the app Tailor to create LuneOS partition or must be created manually.

4. Install Android

5. Install LuneOS (The partition must be already created, or look at my guide for LVM how to create one)

6. If you want create a 2G Linux partition to be use as Chroot in Android by following my guide Click here for how-to-install-ubuntu-18-04-lts-bionix
