No Joy Flashing

First off, Thank You @AlwaysLucky for the details in your post (#54).

Tried twice last night, end up staring at the EverVolv logo for over 30+ mins.

Reset it once to try the boot again and no luck.

I resized the 'system' to 2048. (decided to go overboard.)

Flashed the CM12 items via TPTB, that booted up fine.

Rebooted into 'recovery' flashed the 09-06-16TWRP, rebooted, performed a 'system' wipe

Flashed the ROM and GApps. Locked up / froze at a dark screen. Hard reset.

Booted to Evervolv, and it stayed on the boot animation for over 40 minutes.

Another hard reset, wiped and tried again.

Might just go and start from scratch here in awhile.

_Dan

EDIT: Went and rebooted it after posting and lo and behold it booted up. Went into Apps and immediately it BlueScreened on me. Hard reset, tried again, and BlueScreen again...

But at least it booted up, Pretty darn quickly I might add.

Dev-Base still did not fix attachment issue, did they get your login up?

As per the zip issue, a few guys where complaining about there being no zip file. In fact one guy went through my steps without realizing there was no zip, and is stuck now with a blank tablet. So after I saw all this 'carnage', I put a comment on where to find my zip file on XDA but not with a link.

Yes because you and I put our heads together with some good brainstorming instruction sessions, I think the instructions are now ready for public consumption. What do you think? And maybe after more testing by users, we can do some minor detailed finishing touches.

Thats nice you talked to RolandD, and got some feedback.
[TouchPad Development] shumash:
You really need to open a separate thread on this procedure. It's going to get hidden and forgotten if you don't.
[TouchPad Development] RolandDeschain79:
Totally agree, this method deserves to have its own thread before the info gets lost in this thread.
[TouchPad Development] nevertells2:
Last time I checked, still cannot log in as nevertells. Think I am just going to start a new account.

I agree with Shumash and RolandD, you should start a new thread, probably over on Devs Base

since this one is mainly dead.

Who ended up with a blank TouchPad? What did they do, the complete data reset and resize the

volumes? That should be easy enough to recover from.

[TouchPad Development] ipguy:
Hi all, just got my hands on a Touchpad and am wondering if this it THE ron to install?

Is there any lag ?
[TouchPad Development] DoubleStuff:
a user named Atlas ended up with a blank tablet, I will have to check up on him later or PM him.

I still can't upload a zip to devs-base, so until I can, I am not going to create new thread their.

I got into an ambitious mood the other day, and merged tptb_v42_win.bat with my new bat so the user will only need to run a single bat file now using the new method. So thats my v03 version not released yet. And I am getting in a mood to make a video too, like RolandD does!! "Hello Touchpad users", but nobody does it as good as Roland! He has a voice for radio!!

I was thinking of you NT with only one tablet, and how you maybe want 2 versions of Android maybe KitKat for a stable ROM, and maybe Nougat for experimenting. I was thinking whats stopping us using this "new method" to load 2 versions of Android on a tablet!!??

Call me crazy, but I want you to tell me why it can't be done. I have my thoughts on why not below in the P.S.

Here is my plan to test this later today, highly volatile and experimental

( who knows I may brick my tablet )

1) Have two different versions of uImage.TWRP on my PC ( one for 4.4.4 and other for Nougat )

Only load these as temporary loads, so they don't take space in the boot volume.

2) Then load KitKat and gApps with the first TWRP.

3) Then load Nougat with no gApps with the 2nd TWRP.

P.S. the reason I don't think this will work, it because there is a reason we have to do a complete data reset before changing versions, because one ROM does not like other ROMs files....and not enough room in the boot partition. And there must be a reason why different ROMs use different gApps packages.....
[TouchPad Development] DoubleStuff:
Well the experiment went as follows:

1) Temp Loaded 7.1 uImage.TWRP, and stored 7.1 ROM & Gapps on external mount in folder /7.0.1

at the same time stored 4.4.4 ROM & Gapps on external mount in folder /4.4.4

2) Flashed 7.0.1 ROM & Gapps, and 7.1 Evervolv Android came up with success....

3) Then temp loaded 4.4.4 uImage.TWRP, and flashed 4.4.4 ROM and Gapps...

When I went to reboot, the moboot screen only showed the Cyangenmod 4.4.4 the Evervolv image from moboot was gone!

There ends the experiment to have 2 versions of Android on one tablet, I knew it was too good to be true, but I had to prove it to myself. I was young, brash, and naive. Well as least I did not brick my tablet.....
[TouchPad Development] HP_TOUCHPAD:
You could have endless version of Android on the Touchpad, all the Rom ever created on it. With some creativity and the right brain to do the programing everything is possible!

The principle could be the same as deploy by http://www.android-x86.org/ When you install Android x86 on a PC a folder is created then inside of it are:

data.img

initrd.img

ramdisk.img

system.img

kernel

Grub for Dos Mounts the hard drive partition then loads the Kernel, then the Kernel loads the initrd.img

I envision the same thing, as Moboot (is similar to Grub), A simple shortcut ( very small in size is place in the boot directory to redirect the loading of the Kernel that is on a Folder, then the Image is loaded and all the system.img and data.img are mounted.

Example: Android 4-4-5, Android 5. Android 6, Android 7, Android 7-1-1 will show on the Moboot menu ( but none of the Images are on the Boot directory, only a Link to a folder on a Large partition to the desire Image file.

Then on the Large Partition ( could be Data ) you will have folders, with the names to each android version and inside all those folders are the disk images that the kernel will mount and use.

Now you have folders that can be move easily anywhere, no need to repartitions the tablet.

But a new Moboot needs to be created and all the Images needs to be recreated as well.

It is just an idea !
[TouchPad Development] DoubleStuff:
Somehow I knew it could be done!!, that is have 2 versions of Android on one Touchpad!!

Because its such an UN-brickable device, and the Devs installed software so the user is in control!

Thank you Devs!!!

Now I was thinking of others who maybe have only one device, as for myself I have 3 touchpads with various version on each one for experimentation. So I am very happy with my setup.

That is a good idea put forth, and if you ever want to create a new thread and go into detail for users its up to you. But as for me, I am fine with just one version on my touchpad.

I am familiar with that link you put forth....andriod-x86.org, because early in my Android days

I had an old Windows Vista computer that was slowing down, so I installed Android on it!!
[TouchPad Development] HP_TOUCHPAD:
You can use 3 OS on the same Tablet at once. I use WebOS, LuneOS and latest Android . I do also have more than one Tablet, but is always great to get the most out of it! Also you could run different OS as a virtual Machine, it all depends how much fun you want to have!
[TouchPad Development] shumash:
Old idea. Nook Color had the option years ago.
[TouchPad Development] nevertells2:
Wasn't that done by booting from an external SD card and running the OS from the SD card?

NT.
[TouchPad Development] HP_TOUCHPAD:
That is completely different, the SD card will act as another partition ( or hard drive) which the touchpad does not have. It will be booting from a folder located in the internal storage with no need for other partitions. If this was done http://www.android-x86.org/releases/releasenote-cm-x86-13-0-r1 I will think that it should be possible to reverse engineered to the HP Touchpad. There will be no need to install a ROM, just copy a folder with all the images to internal storage, that's all! BOOT from a Folder !
[TouchPad Development] shumash:
Yup, but the concept is similar.
[TouchPad Development] nevertells2:
I was just questioning about how it was done on the Nook Color. I am quite aware that it would have to be done differently on the TouchPad. As another mountain to climb, it's an interesting idea, but i doubt the interest of doing it on a fading platform will be too high. With the exception of Evervolv, there is no other development left for the TouchPad that I am aware of.

What about invisiblek's nightlies? Currently my daily driver.

[TouchPad Development] HP_TOUCHPAD:
There is also Lineage OS for the touchpad. I am surprise that a Folder install has not been implemented for any other Android device, but only for Androidx86. You will never be able to brick any device by doing a folder install of Android as you will have the original working at all time. If the folder install fails you will always boot to the original ROM. Is like running a Virtual Machine on bare metal, the perfect example is running Windows using a VHD or VHDX. In this case the disk images are IMG files on Android. It will make everything easier, imaging Portable Android for any device!
[TouchPad Development] nevertells2:
Last time I checked the link to his downloads it was dead. I just checked it and it's working again, so I amend my statement to include his Rom.

So yes, invisiblek's build is still with us, and you make my point. Other than Androidx86, no other devices are using a folder install approach. Maybe sometime in the future, but on a fading platform like the Touchpad, I doubt it. You seem to understand this approach quite well. Will you be the person who sets it up and instructs TouchPad users how to do it?

I wish I have the Knowledge of an Android developer to create the set up. But I am guessing it will required a new Moboot or a replacement and also a new Kernel to mount the IMG disk and use it, I am guessing . I can only dream about it, others could make it a reality!

I use to use this https://github.com/init2winitapps/BootManager

And this

https://github.com/Tasssadar/MultiROMMgr

I'm sure these could be implemented easily.

Is there an annoying leftover volume that shows up as an sdcard when anyone does a complete data reset on their tp? Mine was showing an unusable sd card and couldnt format it. Anywho I managed to delete it via nova terminal. Seems fine on the newest nightly and doesnt show up anymore.
[TouchPad Development] shumash:
That annoying sdcard is used by TPToolbox. Without it, you can't use the tool.
[TouchPad Development] bryantjopplin:
I did, I Wonder if it just for the install of android side? Worked fine after the removal. I only use tp toolbox for resizing the volumes. I load twrp via novacom and install that way. We will see, but all is well still. Not hard to add it back if needed.

[TouchPad Development] tpuserhp:
BGrosse, I saw your post in devs base asking about background process limit. I don't have an userid there. But you can automate the process of setting this value after boot. But you need to install an app like init.d scripts support and runs a script to change the value after boot. If you are interested, I can look it up for you.
[TouchPad Development] BGrosse:
Hey [MENTION=5333182]tpuserhp[/MENTION],

I would love to get some help on this. I know (feel) this could be done, but digged not in to deep to get a solution right now. If you have the terminal command for this setting, I will find a way to get it applied on boot. ATM I have 3C Toolbox Pro and Kernel Adiutor on hand. One of them should do the job. :cowboy:

Thanks in advance!
[TouchPad Development] tpuserhp:
The command is as follows to change the bg process limit to 4:

service call activity 51 i32 4

To change it to 3, just change the last number from 4 to 3.

You can run the command in terminal emulator to test it out. Issue a su command first.

Hope it works for you.
[TouchPad Development] BGrosse:
You are my HERO!!! Worked like a charm, entered in the Terminal emulator of 3C's Toolbox. :D

Now just have to figure out how to apply it on boot. Is it possible to append it into the existing init.d just with root file explorer and editor?
[TouchPad Development] tpuserhp:
Glad to know the command works. I have not tried out your method. I found people use the app I mentioned previously with no problems. I wrote myself an app to listen to the boot event and run my script. You might try your method and let me know how it goes. But take a backup first.
[TouchPad Development] BGrosse:
Hi [MENTION=5333182]tpuserhp[/MENTION]

tried the app, then kernel adiutor, then 3C Toolbox. I used Toolbox to generate the script file with this command line and let Toolbox run on boot. Rebooted several times and it seems to work. So I don't need another app since Toolbox can do this job. Works great! :cool:

Thanks for this one! :highfive:

BTW, where did you get this info from? Is there a list with commands and arguments available?
[TouchPad Development] tpuserhp:
Thanks for the update that Toolbox works as well.

I found the info a while ago and I did not keep the post which suggested the command. I just kept the command info. It was for Android version 5 and I needed to change the number from 50 to 51 for v7.

I did another search just now and found the similar info.

https://github.com/flode/SetAndroidProcessLimit/issues/5

It mentions API info that I think is what you want. I hope this helps.
[TouchPad Development] BGrosse:
Thanks for that!

I attached the script file for anyone who wants to use it. Just unzip it and copy it i.e. to /sdcard/Android/data/ccc71.at/scripts

Afterwards get into 3C Toolbox, select Scriptmanager, select Script (upper left button), navigate to the path you placed my script into and select it, save it and check the leftmost icon (next to the "X") to execute on boot and you should be ready to go. :cool:

How does anyone feel about the L Soeed app available here on XDA? Good by itself or specific kernel tuning app with or instead of it? Kernel Tuner is causing big temporary freeze ups and L Speed has things specifically tuned for great smooth video and gameplay. Please try and let me know. I love this immortal tablet.
[TouchPad Development] MikeN68:
Gborg3. Sorry if I am out of line here, but have you tried L Speed? Are you just asking others to test it before you give it a go? If you have tested it yourself, what are your comments?
[TouchPad Development] HP_TOUCHPAD:
We had this discussion on here: https://xdaforums.com/showpost.php?p=70648447&postcount=843

The use of loading any uImage into memory using "novacom boot mem" has always been use on any WebOS device. That is what the bat file does, there is nothing new but a great feature to use on the HP Touchpad. It is great to see someone dedicating their time and make it easier for others users to update their Tablets with less confusion possible.
[TouchPad Development] Gborg3:
L Speed I'm using in conjunction with now Kernel Adiutor on my touchpad and on two Oppo Find 7's. I haven't noticed any freeze ups with it and it does have some extra adjustable bits and does seem to improve smoothness. I forgot how feature filled Kernel Adiutor is so id like to figuratively kick myself but it's still missing some of the more interesting features of L Speed. With both together I'm noticing no issues and I'm surprised, impressed and curious if this is replicable. Also, no apologies necessary my fellow touchpad user.

Battery Drain even at Plane Mode

I'm facing fast battery drain even at Airplane Mode, before I do a Clean install my battery was during a week at this mode. The only thing I changed is the F2FS to the partitions. Anyone facing this problem? Is there anything to do with the partition mode?

I installed L Speed app from the play store last night on my March 28 nightly rom. I also made a switch to Dolphin browser and uninstalled some apps too. I set the Profile in L Speed to performance. So far, the performance is consistent, even though couple of times I need to turn off and turn on the screen to make the screen touch going again. I'm not running the big apps like Google and Facebook on my device.

I'd recommend to give the L Speed app a try if you are having performance issues on your device.

Hey folks,

I seem to have lost my mind.

How do acquire root on the TP once ROM installed?

I have tried the playstore and twrp install and neither work.

Toolbox? But can't find the option

Thanks in advance.
[TouchPad Development] tpuserhp:
I'd suggest that you visit the following website and review the recent posts there.

<Mod Edit: Link removed. Please don't redirect members to other mobile forums. Thanks!>

Also, the following was suggested by Flintman there:

https://download.chainfire.eu/696/supersu/*Download this and install via TWRP then update app in playstore and update the su binary via app. I need to look into why they latest won't install anything right.

Hope it helps.
[TouchPad Development] Rolfsted:
Thank you.....I was wondering the same thing.
[TouchPad Development] toolmanz:
You were absolutely right. A read through the threads and problem solved.

There is a caveat though .... make sure you use the su version that is recommended (2.46) in the thread. Download here https://download.chainfire.eu/696/supersu/*Download

I tried using, I think, the later version 2.49 and that didn't work. Never showed up as an available app.

Happily rooted ever after :laugh:

I did a complete data wipe and started fresh from the toolbox. I followed the instructions in post #3.

Then i installed the April 6th build and the newest gapps. It boots up but I cant get through the setup wizard, it keeps crashing. It crashes right near the beginning, where it asks if a new device or restore.

I have tried all options but the setup wizard keeps crashing and I cant get into anything. How to i fix this? Any suggestions?

So, I tried the April 4th and same issue. Then I tried the 3rd and it works. Seems to be 7.1.2 related.
[TouchPad Development] nevertells2:
How much did you read? It has been established that the problem exists when a clean install is done. If you clean install an older build and then dirty flash the newer Rom, you bypass the set up problem.

I have read it now. The site was down when i tried yesterday. Thanks!!
[TouchPad Development] johnbelloh:
I started testing this rom a couple of weeks ago. I have 48 apps installed including the larger ones like Facebook and the Chrome browser as well as Dolphin. I started with a clean install and have the memory partitioned as recommended except for cache which I have doubled from 200 to 400. I tried increasing the system size but found the system ran slower and restored it back to 1312. As a "daily driver" I am pleased to report that all 48 apps work some perfectly like all four of my mail accounts as well as the smaller apps. I have been updating with each nightly. The larger apps like Facebook will load slowly at first but if coaxed along will pick-up some speed and are usable. However yesterday's nightly 4/13 will abort Facebook as soon as you try to scroll forcing me to restore my 4/10 back-up. I love the rom and thank the developers for doing this. I have a bunch of touchpads running various roms and will spend most of my time on this rom and report back my findings to help Flintman and all the others involved in this project. I also owe Nevertells a thank you for getting me to move up from Milaq's 12.1. to this great rom. A big thanks to all of you.

Update - I just flashed 4/16 and Facebook still crashes - restored back to 4/10 and Facebook does not crash. I will report when a future nightly works with Facebook. Thanks
[TouchPad Development] acetone802000:
hello,

for an "fresh install". What version of file do you install?

(i was on 4.4.4, resize system to 1312)

i downloaded the 7.0 http://evervolv.com/get/ev_tenderloin-7.0-testing-2016.10.05.zip (at the 1st post). installed without any problem with open gapps 7.0 pico (twrp 3.1.0-0 at 3rd post)

but after boot i have an error:

i also tried http://evervolv.com/devices/tenderloin but with open gapps 7.1 arm pico it crash at settings.

( i can access only nightly from 04.02 to 04.13, i don't see older nightly)

thanks in advance

edit works with: http://evervolv.com/get/ev_tenderloin-7.0-testing-2016.09.06.zip
[TouchPad Development] AlwaysLucky:
The OP is no longer updated and that ROM version is very old.

Follow the links in post #3 for current roms, and follow the guide in post #3 for a fresh install.
[TouchPad Development] acetone802000:
of course, but at evervolv.com i can't find an old ROM who works.

At this moment you can only find nightly from 04.02 to 04.13, i don't see older nightly
[TouchPad Development] AlwaysLucky:
The new builds work great and there is no need to use earlier versions. If you're having any issues with the new builds, perform a "Complete Data Reset" as described in the guide in post #3. Also be sure to use the newest TWRP version, which is also linked in post #3.

It's common for the file system to get corrupted or muffed up, but a Complete Data Reset solves the issue 99% of the time.

Good luck! :cowboy:
