Actually, I wondered about that myself. a couple of days ago I used Android Image Kitchen to unpack both the posted boot.img and the recovery.img

The ramdisk folder from the boot.img was empty. However when I unpacked the recovery image and the Magisk patched boot.img, the ramdisk folder was populated, like what I have seen on my Android 6.0.1 devices.

So I also wondered why the boot.img, instead of the recovery is patched in this case. I am assuming because recovery is in a separate partition, just like old, on these devices, instead of recovery being in the boot.img, like on many SAR devices. Forgive me for my lack of understanding the new, SAR, A and A/B devices. I assume this device is A only. From Mixplorer without root, it appears to have a system folder, not system as root, or am I wrong, viewing this without root?

@tek3195 and [MENTION=4519203]NFSP G35[/MENTION] Thanks for all of your great input. I just had a thought, I could just temp boot my new Magisk patched boot.img. At least this works on my Android 6 Nextbooks. Do you see any problems with this approach on this device? I tried it with the stock boot.img and got:

marty@marty-Inspiron-570 ~/Downloads/Onn 8 boot img backup $ sudo fastboot boot boot.img
[sudo] password for marty:
downloading 'boot.img'...
OKAY [ 0.536s]
booting...
FAILED (remote: not allowed in locked state)
finished. total time: 0.540s
marty@marty-Inspiron-570 ~/Downloads/Onn 8 boot img backup $

And, of course, unlocking the bootloader, first. I also figured out how to remove the clock from the desktop.
[Walmart Onn Tablets General] tek3195:
I don't think you will be able to temp boot anything on this tablet. It didn't work for me, and when I tried it I had to boot into windoze and use tools to recover it. That was before I thought about removing battery when its unresponsive to everything. That may have worked then, don't really know, but I wouldn't recommend trying it. I've followed guidelines at Source Android for testing recovery by booting it, and wasn't able to make that happen either. This thing can be very picky about what it accepts. One other thing I just ran across: OTA did not work when I tried to go back to Onn to check some things with new update. I flashed the stock system, vendor, vbmeta,boot and recovery then rebooted into recovery with "fastboot oem reboot-recovery" and tried to apply update from sd card. I had update.zip from adups/fota saved just for that. Anyway it failed to finish verifying and said the system had been mounted read-write 9 times and system image couldn't recovery. Don't know what it couldn't recover from as it booted just fine, but this tab is keeping tabs on what we do and counting modifications. I'm going to see if adb produces same failure with update or not in a while. I literally just ran into this so have any idea what to be done to make OTA's work. Keep in mind I've also been using different GSI's for the past week or so which could effect it but I don't see how.
[Walmart Onn Tablets General] DB126:
I may sample a few GSI's but am in no rush to proceed as the device performs acceptably w/stock (keep in mind this is not my primary tab). Exciting takes on a different meaning when it's all salt and no pepper. Guess I'd need a use case to justify tinkering with something that ain't broke. At present there's nothing that distinguishes this device from others in my portfolio sans price and a nice size panel running near AOSP 9 that is still light enough to hold for prolonged periods. Stability ranks high in my book; so far pup has delivered w/o having to break out my toolbox. Been there / done that too many times. :)
[Walmart Onn Tablets General] martyfender:
I am up and rooted with the latest Canary Magisk. I chose Canary because there was a WIP for the exact error in additional setup required failing on Android 9, on the tablet I returned. Otherwise I would have stuck with the release, v20. I just installed Adaway and it is working just fine with the Magisk systemless hosts module.
[Walmart Onn Tablets General] Vortell:
If I remember right to take ota on essential phone it had to be adb oem flashing locked state again. They had the updates packaged separate for TWRP/Root users. So maybe this ota checks for it too. As for the 9 times the system was mounted how many GSI images have you tried? I assume there are more then 9 publicly available.
[Walmart Onn Tablets General] tek3195:
Yeah, way more than 9. I believe I counted 37 between official and unofficial on phhusson's list on github. https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list . Got tired of setting device up with all the customization it was a bit much. Some of them you can spend an entire day just tweaking the ui. Taking a GSI break for a few days to do some maint. on a few things. Got a Tab S2 that data side of usb went out, charges fine but no data connection. The display is nerve wracking to me, thin, fragile and $200 just for parts. yeah, broke one last year.

Been meaning to post a list of which GSI's worked and didn't work. Maybe it will help people wanting to try them out, because if you start out grabbing one that doesn't work on this tablet then you don't know if it's something you did or what and the GSI experience will have left a bad taste in your mouth forever. I'll try to put up in the next day or so.
[Walmart Onn Tablets General] tek3195:
Perfectly understandable. Can't blame you for that. One thing I haven't mentioned is this thing runs high-end games. Or at least CSR2 it runs perfectly fine. Just throwing that out there, come to think of it, that was exciting for me to figure that out.
[Walmart Onn Tablets General] CaffeinePizza:
I've ordered the 8" 002 model. I'll post a dump of it made with Wwr mtk tool and SPTool when it arrives.
[Walmart Onn Tablets General] Vortell:
How did you decide to use sptools rather then other ones available. How hard is it to use? Oh and I would love to know about which gsi's worked best. Plus I like UI customization like in Havok,AICP, or RR. Need full backup of 0007 model.

[Walmart Onn Tablets General] lockback:
Yeah, and I when I went back to the kpoc_charger file it still had the command I put in. I even tried renaming that file to something else and plugged it in and still saw the animation.
[Walmart Onn Tablets General] martyfender:
My initial impression of this Onn 8 device was negative. Now that I have it rooted with Magisk and have got over the learning curve of Android 9 I am absolutely loving it. It is so much better in almost every respect compared to my 4, Nextbook Ares 8A's, Intel x86, Android 6.0.1 devices. Overall it is faster. I get no lag on wake from a long doze where my Nextbooks spend several minutes running, I assume because of all of the Google services to update and synch, etc.

Although I have installed Kernel tuning apps such as Lspeed and Kernel Aduitor, I believe the devices default appear to be pretty good, so these app may only be minimally beneficial. I have, for example, lowered the scrappiness setting from the device default of 60%, to 40. Maybe with the devices 2gbs of ram it could benefit from an even lower value. Any thoughts on this?

Overall, I am very impressed with this inexpensive device. Only time will tell about it reliability and longevity. 1 out of my 5 Nextbook Ares 8A's have died already. On 4 out of five of those, the external SD card slot has apparently failed, therefore I have the stock twrp backup in internal SD, which consumes considerable space, even without the data, I did not backup with stock.

My next step may be to buy Titanium Backup Pro to back it up. I do have Sp flash tools on my Linux PC. Can I backup with it or do I need to use the WwR solution.? I have not been to that site yet. I think it was linked.

Wow TB is super complicated. Does it backup the whole system image, boot, etc. I don't see a backup everything. If this doesn't backup boot, system, recovery, etc, it may be useless to me. With those restored and booting into Android setup is all I really need. However, with enough storage, restoring data can also be useful. I guess I was spoiled by twrp on my Nextbook devices.

I am not certain on can image a live system in Android.

I haven't searched yet for a thread for TB, as this may be getting OT here.

Thanks
[Walmart Onn Tablets General] NFSP G35:
OK, skip that... I just tested this and it worked on mine:

Reboot into fastboot and run:

fastboot oem off-mode-charge 0
[Walmart Onn Tablets General] tek3195:
Not a clue. You may want to ask in a treble thread maybe. Or ask [MENTION=4544860]osm0sis[/MENTION] he is a boot wizard. If anybody would know he would.
[Walmart Onn Tablets General] DB126:
No need to get too counter-aggressive w/swappiness as ZRAM management is far better than on your previous gen devices. Really depends how fussy you are on active multitasking. Winding it down will yield faster switching at the expense of maintaining context. At some point LMK will start pushing stuff out of RAM which will be noticable when switching. I'd play with LMk values first if you must tinker. As for further kernel tuning ,L Speed tweaks, etc...well, you know my opinion there.
[Walmart Onn Tablets General] osm0sis:
Clever idea, though I think system might not be mounted for charging mode, and usually there's a charger binary in / or /sbin in the boot.img ramdisk. You could try replacing it, but it'd need to be with a static reboot binary so that it wouldn't need system mounted... My busybox binary renamed to reboot could be an option there.

Even easier, I think it's generally mediated by the bootloader as well, and your bootloader might support disabling offline charging with `fastboot oem off-mode-charge 0` (or 1? It was never clear to me which it was).
[Walmart Onn Tablets General] NFSP G35:
Before it gets buried even more, I already posted the solution
[Walmart Onn Tablets General] martyfender:
Thanks for your response. So keep swampiness at 60%? My guess is that Greenify as a Priv-system app is also a waste of time on this device? However, Adaway with just a couple of hosts sources, Steven Black and Jawz101, make a great difference And also Firefox with Ublock Origin.

I'm not much of a gamer anymore, but GT Racing 2 runs much better on this device. That is the only game I have installed.
[Walmart Onn Tablets General] DB126:
- leave swappiness alone

- I use AdGuard so can't comment on your cocktail

- no need for Greenify

Hyper-moding modern Android is akin to touting Unix skills as an asset. Once relevant but no longer necessary (die hards will disagree, of course). I prefer to use my gizmos vs (over) manage them. Enjoy your Onn.

I'm glad you brought that back to my attention. I couldn't get path completion to work in terminal emulator before, decided to give it another go and working now. Thanks

No problem. I usually switch over to Hackers Keyboard for terminal emulator. That way I have a tab key, ctrl key, and don't have to fight with Swiftkey autocompleting everything lol
[Walmart Onn Tablets General] martyfender:
I have been reading the tutorial on hovak on how to use the WwR tool with spflashtools to backup the rom. I usually am the person who can jump in to something like this, but it seems to be so complicated.

So maybe doing a dd backup would be better for me. I did it about 2 years ago following at web link which I don't have anymore on my newly installed Linux Mint Mate SSD. On my Nextbook Ares 8A's I could use a root file explorer to find the partitions by going to: root /dev/block/platform/pci0000:00/80860f14:00/by-name and by-num to get, for example, mmcblk0p11 for android_system.

With Android 9 these are very different and apparently don't show up or are different. Diskinfo Pro gives a message about it not being able to show many partitions in Android 9. Can someone recommend how to proceed? Since I have a copy of my boot.img, is it sufficient to backup the stock system.img and the stock recovery.img, assuming I don't do anything stupid to mess up all of the many other Android partitions.

If so, can some post the commands to do this with dd? would these be correct:

dd if=/dev/block/by-name/system of=/sdcard/system.img
dd if=/dev/block/by-name/recovery of=/sdcard/recovery.img

I just did the above commands and they appear to work.

Can one do this, but copy to my external SD card, instead, for future reference? Of course, I am now copying them manually from the internal to the external SD card.

The images are 16M and 2.3G respectively.

[MENTION=8491352]tek3195[/MENTION] If I decide to dd copy the other partitions, can I use the names of the images you posted on gdrive in dd or are the commands different, for example:

dd if=/dev/block/by-name/vbmeta of=/sdcard/vbmeta.img

Is the below just for mtkflashtool:

dd if=/dev/block/by-name/preloader.bin of=/sdcard/preloader.bin

Do I only need to backup the .img files to flash in fastboot?

Hopefully, I only need the 3 that I backed up, unless I really mess up the device, somehow?

Thanks to all of you who have been very helpful to me with this new device.

I absolutely love it. It is so much better than my older, Android 6.0.1, devices.

UPDATE: I have apparently successfully copied, vendor, vbmeta, dtbo, system, recovery and boot, so far to the internal Sd card.

I do not plan on trying any of the other roms that were linked and only plan using apps and doing Magsik updates, so I hope I will be reasonably safe..

The first device, which I returned, was bricked because I flashed your system.img, then tried to use spflashtool to do it. Spflashtool apparently messed up the bootloader, as it showed up in fastboot devices, but would never flash anything else. I assume my device had a newer revision somehow of the rom and or hardware, not really sure.
[Samsung Galaxy S10+ Questions & Answers] scoob101:
I`ve just upgraded from a S7 edge to an S10+ and the main thing I miss is the ability to double press the home button on the S7 to trigger the camera app.

I have mapped a double press of the bixby button to the camera app, but that will only work once the device is unlocked.

Is there a way of triggering the camera app directly with a hardware button press when the screen is turned off??

Greeting,

I have a weird issue where occasionally after I unlock my phone, my screen doesn't respond to touches.

The phone works and responds to physical button presses but not touch.

Not sure exactly when it started happening but I've noticed this since last week.

Any idea what might be causing this?

I'm running Android Pie 52.0.A.3.202.
[Sony Xperia XZ2 Compact Questions & Answers] MartinX3:
Please upgrade to the newest firmware.
[Sony Xperia XZ2 Compact Questions & Answers] viktor1983:
Got the same issue on 52.0.A.8.50. Usually opening the app drawer then hitting back solves it - otherwise none of the virtual buttons work.
[Sony Xperia XZ2 Compact Questions & Answers] bobsright:
Searching the web it seems touch screen issues are pretty common on this phone. I'm a bit surprised there isn't more being said here about it. Some experience delayed response, dead areas and no response at all. I have all those issues. Yes I am on the latest firmware. I bought the phone used with a cracked screen. I checked it out and everything seemed fine. I didn't use the phone, just set it aside til replacement screen came. I should have used the phone to thoroughly check it out but didn't want to go through the set up process as I was thinking of B/L unlock and root. New screen came, put it on and seemed to be working fine then screen would be unresponsive. I did factory reset, software update, software repair, went into settings and made sure sure everything was good there, nothing helped. The center of the screen (it's low and a bit off center) is pretty much dead. To open launcher I have to touch and hold near the top of the display. Touch and hold apps is tricky. Usually the app just opens. When I do get it to hold, I can't drag it anywhere. Also, icons in the drop down menu cannot be rearranged or edited. I can swipe up/down, side to no problem. Whenever touch goes dead completely, the home, back and minimize buttons go grey. Tapping the power button gets them back functioning again. . Function test fail. Free draw lets me make a few seconds of scribbles then freezes. The x and rectangle block draw does the same. Tapping power button does nothing to unfreeze either. The color test pass even the block one where you toggle on/off sections of the screen in blocks. It's really weird. First impression would lead me to the screen but it really acts like a software issue. From what I've read so far this phone uses two different display drivers. I not seen anything on how to change that and it would more than likely mean B/L unlock and root, which I'm not against doing. I would just like to know definitively if it's hardware or software. Any input would be greatly appreciated.

Thanks
[Sony Xperia XZ2 Compact Questions & Answers] MartinX3:
Maybe the Screen Connector wasn't 100% clean.

Or not only the screen is damaged.

I heard that the touch problems are mostly fixed with PIE. The closed source clearpad touch driver is..... Hoping Q gives us an further updated driver.

You still get sometimes ghost touches on higher workload or if the keyboard app is slow, but if you have dead spots the hardware sounds damaged.

THIS IS A ONE-OFF TEST BUILD

I built this ROM as a way to check the features of a Pie LiquidRemix ROM. It is very closely related (feature wise) to Havoc-OS.

Flash at your own risk etc etc.

[Galaxy S 4 i9506 Android Development] DiamondJohn:
I only had a short time to play with it, and the main purpose of building the ROM was to compare the features with Havoc-OS. What would like to see is a comparison of features between Havoc-OS and this one. I guess if you find a feature in LiquidRemix that is not in Havoc would be the most interesting.:good: I thought I saw some, but I just flashed Havoc-OS and they were also there, if not taken further.

I watched some YouTu be clips which seemed to suggest LiquidRemix was ever so slightly faster, however, the difference was so minor that correct configuration would more than make up the diff. Anyway, on my personal builds, I add a big list of CPU Govs and IO Schedulers, plus I also run a whole heap of boot scripts. see the following thread for the list of the govs and schedulers https://xdaforums.com/galaxy-s4/i9506-develop/rom-havoc-os-diamondjohndroid-t3884067
