Xposed helps a little, but doesn't solve it, to be honest the little help xposed provides isn't worth the time of installing it. But you can install and setup xposed if you want, use x86 version.
[Miscellaneous Android Development] freddy999:
Thanks, I might give it a try. I doubt it can make it worse! Do you know of any other fix I might try? I see apps hanging for no apparent reason at random, not often, just often enough to be a pain.

You seem to have the experience with this device missing in most who are trying to better it and I highly value your insight!
[Miscellaneous Android Development] vampirefo:
The only really tangible fix I have found is flashing 5.1 firmware, that fixed the leak completely, and makes the over all performance of the tablet better.

Two side effects that I noticed, might be more as people use their device differently, sound is low and camera doesn't work.

I never used camera before, so no loss for me, head set volume is just fine, which is the way I listen to sound anyway so low speaker sound doesn't bother me either.
[Miscellaneous Android Development] Masterchief2017:
Where can I find an android 5.1 rom (or what ever i need) for this tablet?
[Miscellaneous Android Development] vampirefo:
You can't, you can try xposed if you want though, perhaps remove unused apps.

The 5.1 is still in testing phase, sdc is working on some roms, and he suggested hudl2 as a possible source for 5.1.

Those might be a better, choice for those that can't wait for me.
[Miscellaneous Android Development] social-design-concepts:
EDITED : Don't really care. . .
[Miscellaneous Android Development] Masterchief2017:
Do you know how long it will be before you have it ready and can release it?
[Miscellaneous Android Development] vampirefo:
Well, I am on vacation in Florida, it will be a while week or so.

My method is long takes time, results are great, well at least I think so.

I would still suggest using sdc method and hudl2, that firmware is ready available, and sdc says he believes partitioning and changing bootloader is unnecessary, so basically with his method and ROM, you just flash the hudl2 rom and you are up and going.

If I knew it was that easy, I probably would have went that route myself, anyway good luck.
[Miscellaneous Android Development] Masterchief2017:
Thank you. Do you have a like to his forum?

[Miscellaneous Android Development] social-design-concepts:
That's not actually what i said , so first let me be clear i do not recommend flashing any ROM from another device onto your device with out doing some extensive research first that's just 100% a bad idea,

what i was suggesting was that a ROM from another device could possibly be ported to another devices with modifications to the boot and system images and was using the hudl2 as an example because of it being available.
[Miscellaneous Android Development] vampirefo:
You suggested partitioning and flashing bootloader was unnecessary, so to me that means just flashing ROM.

You no longer think hudl2, is a good choice?

How can users test hudl2 firmware without installing it?

I personally think it's a bad choice, and won't bother with hudl2 firmware.

So what are recommending people to do, so it's clear, use don't use hudl2 firmware, flash don't flash bootloader? Partition don't partition?
[Miscellaneous Android Development] vampirefo:
Guys, my suggesting following sdc method is for people who can't wait for me to post my guide.
[Miscellaneous Android Development] social-design-concepts:
"so to me that means just flashing ROM " that's kinda a really loose assumption, yeah your just flashing a ROM if someone has already done the work of porting that ROM.

if the bootloader is already insecure / unlocked and the device already has a large enough system partition, i wouldn't see any reason to replace the bootloader or re-partition the device that be the very last route i would take.

I know this isn't the case with the iview bootloader but the #1 reason why flashing the bootloader should be the last resort is you don't know what's in it, there is an actual build flag that can be set when building some Intel android bootloaders that actually will brick a device when a user attempts to unlock the bootloader requiring the device to be reflashed with a external programmer.

Honestly haven't looked at the ROM i grabbed it for the blobs and to track changes in the .rc scripts between 5.0.x and 5.1.x but no as vanilla as iview is it is probably a better options but i still wouldn't think you need to replace the bootloader or repartition the device to use it as a base for porting.

They couldn't your porting another devices ROM to your device that is an involved process. First you need to create your modified boot.img kernel / modules any needed changes to .rc scripts, disabling verity etc. then you have to modify the system.img device specific blobs, config files, permission files, build.prop edits, disabling verity etc. etc. etc.

it's porting, it's work, but again you shouldn't have to change the bootloader or repartition the device if the bootloader is already insecure / unlocked and the device already has a large enough system partition.
[Miscellaneous Android Development] vampirefo:
So what you are suggesting is a TWRP backup? No modifications needed, I make a TWRP backup, ares8 users restore it and all is well?

I may do it that way then, would be easier, just backup system and boot.img, I could almost do that from here, need to check on size of system though.
[Miscellaneous Android Development] social-design-concepts:
possibly but i suspect the boot.img might need some adjustment since you did a full re-partitioning of the device and there should be some things in the build.prop that need to be removed / edited regarding the persistent-data partition. then there is fixing audio and camera, you could always find a single user to work with on debugging.

if you want i can work with you on making it work on my Lenovo and then if it is possible todo with out bootloader or partition modification we can do a write up for applying it to other devices.
[Miscellaneous Android Development] vampirefo:
I think the problem they run into is not flashing bootloader, fastboot, and partitioning to match bootloader.

I think they would have a mess on their hands.
[Miscellaneous Android Development] social-design-concepts:
when flashing cm or omni or any other 3rd party ROM you almost never see the need to replace the bootloader if it's already insecure or unlocked, and you only see repartitioning when the factory system partition is too small, why should porting another devices ROM be any different?

if you wanna see if its possible with out bootloader mod or device partitioning the offer stands you can PM me a link to a TWRP backup of the boot.img and system.img but thats up to you.
[Miscellaneous Android Development] vampirefo:
Well the first time I flashed my tablet without flashing bootloader, I couldn't get pasted the unlock screen due to this or that crashing.

I couldn't click OK fast enough, flashing the bootloader fixed that, no crashing since.
[Miscellaneous Android Development] social-design-concepts:
well again if you like you can always pm me a link to the rom.

[MENTION=2472806]vampirefo[/MENTION] I have a big problem, I compiled TWRP3 for this device and flashed it, and when I boot I get this error then a neverending bootloop:

[ 5.751249] SysRq : Emergency Remount R/O

Same error if I boot normally, I don't know how to get to the bootloader, and if i try to use DnX mode to fastboot flash recovery, I get this error:

sending 'recovery' (15754 KB)...

finished. total time: 0.422s

And then I get this weird boot menu (see attachment, rotate it) and I can't select anything. Please help.
[Miscellaneous Android Development] social-design-concepts:
thats the uefi / bios access menu you'll need an usb otg adapter and most devices ( not all ) require use of a powered usb hub ( which i personally recommend regardless as devices that use more power can short out the port ) and keyboard and mouse to navigate it. but it looks as if you esp is corrupt if you have the efiloader and droidboot.img you can try.

fastboot flash osloader efilinux.efi
fastboot boot droidboot.img

this should get you back into droidboot / fastboot where you can then partition you you device and reflash the esp and the reset of android.
[Miscellaneous Android Development] vampirefo:
Yeah, I have twrp 3 for my devices also, anyway follow sdc advice, to get your device up and running.

If you want to see what each little square does you don't need a powered hub unless you want one, I use hubman from Walmart cost $5, can run keyboard, mouse, usb drive, all just fine with ares 8.

Ares 8 will supply the power to use the hub, you also need otg cable to hook the hub to tablet.
[Miscellaneous Android Development] Startrek852:
Do I need a hub or can I just use a OTG adapter?
[Miscellaneous Android Development] vampirefo:
Otg is fine, hub just allows you to use, mouse and keyboard at the sametime.

May be better for some and I like the way it operates. But screen seems to no want to rotate for me. Ppsspp turns black when the nav bar disappears. Probably a quick fix but I can't get files moved to the SD card. Only messed with it 15 minutes or so. Gapps keeps chasing which I know is a easy fix. I was gonna flash xposed but couldn't get files moved to SD. It boots faster and seems better just don't have time to mess with it right now. Thank you for your work vampirefo
[Miscellaneous Android Development] freddy999:
I had the same issues, so I installed a third party screen rotater and had a major issue on the reboot. I am working right now to put the old system back on to see if I fried anything. I assume all is OK and if so I will give it another try.
[Miscellaneous Android Development] vampirefo:
I am not seeing any rotation problem, rotates just fine for me, I do lock it in portrait mode most the time, but just checked, rotates as it should.

Did you update all the apps at playstore?

I don't try to install apps from backups, apps really should all be fresh, old apps and data could cause problems cause they were for a different OS.
[Miscellaneous Android Development] vampirefo:
Sounds like you didn't allow tablet to update, and installed app backup from Ares 8, that will cause problems, with a fresh OS, you need to only install fresh apps, not backed up apps from old OS.
[Miscellaneous Android Development] Rls4ever12:
I wiped everything and reinstalled without using titanium backup and fixed the gaps crashing screen will not rotate for me unless using a app to do it but getting used to it. Not using backups from ares 8 rom also fixed the other problems I was having. Thanks again [MENTION=2472806]vampirefo[/MENTION]

---------- Post added at 10:52 AM ---------- Previous post was at 10:47 AM ----------

Tried several times to get xposed installed with no success if anyone gets it post a link please.
[Miscellaneous Android Development] freddy999:
Overall, I am tickled pink with this ROM. All of the issues with the video rendering with hardware overlays seems to be gone, the system is smooth and solid. I know Quadrant is not a good tool, but the scores went up from 18,000 to 124,000! The issues are minimal. I have the same screen rotation issue but I run Nova launcher and use it in forced landscape mode, which solves the issue for me. The sound is the only real weak point and of course, no camera. Bluetooth works, although the sound is similar to the speaker and a bit rough compared to regular headphones. This is definitely an improvement over the ARES8 5.0 ROM.

For any who want to try this the TWRP backup seems to be a simple way to install it. I had no issues at all with the install.

Great work Vampirefo!
[Miscellaneous Android Development] Startrek852:
I have a question. Would it be possible to install Android-x86 on this tablet?
[Miscellaneous Android Development] vampirefo:
I don't know, you could try if you want.
[Miscellaneous Android Development] Startrek852:
OK, can you help me figure out how to install it?
[Miscellaneous Android Development] vampirefo:
No, I am not interested in it.
[Miscellaneous Android Development] zerozed99:
Just want to thank [MENTION=2472806]vampirefo[/MENTION] for providing that nandroid backup of the rom he created. I got it running and it has made a world of difference. The only issue I've encountered is the rotation problem which I've gotten around with an app called "Floating Rotation." I've never used the tablet's camera and I always use earbuds so if there are issues with the camera or speaker I don't really care.
[Miscellaneous Android Development] vampirefo:
I don't think anyone has, the rom is available to all to modify as they see fit, hopefully any improvements made or found are shared with the community.
[Miscellaneous Android Development] Startrek852:
OK, I'll try it tomorrow after I unbrick my friend's tablet.
[Miscellaneous Android Development] vampirefo:
I have added twrp 3 to first post for those that want to try it.
[Miscellaneous Android Development] Rls4ever12:
Can the twrp be flashed by twrp or has to be adb
[Miscellaneous Android Development] vampirefo:
By twrp or fastboot

I think older version is better, but it's available for people that want it.
[Miscellaneous Android Development] zerozed99:
I'm posting this solely for lurkers contemplating whether or not to use the iView Suprapad backup that @vampirefo has so graciously provided. I've been using this "rom" heavily for the past 24 hours.

Cons:

you lose auto-screen rotation (can be mitigated--not fixed--with apps from Play Store)

Speaker volume lower than stock ROM, but not inaudible. Headphone volume NOT affected

Cameras do not work

Positives:

Android 5.1.1 (newer than stock ROM). No memory leak, no lag, 100% better

Rooted

Faster boot-up (~1 minute & immediately usable)

Minimal bloat (contains apps like FB/Twitter/etc. as system apps, but can be uninstalled with app from Play Store)

No issues with any apps (I did a full wipe before installing & re-installed 99% of my apps from Play Store, only used Titanium Backup to restore F-Droid )

Ability to cast screen. I tested this with a Roku 3 and it worked flawlessly.

Other notes:

The iView "rom" has soft-keys for volume alongside the "home" "back" and "recent apps" soft keys. Battery usage *might* be a bit higher than stock, but difficult to say since I was running CPU governors, etc. on the stock Nextbook "rom." Regardless, the battery drain isn't significantly worse. 21,468 47791 score in Antutu-- about same significantly higher than stock Nextbook if I recall correctly. Running 32 bit Android 5.1.1--I can't recall if the Nextbook "rom" was 64 bit or not.

You'll have to decide for yourself whether or not the iView "rom" will work for you. Perhaps someone will figure out how to fix the "cons" I've listed, but even if they do not, I'm sticking to this image. The tablet's stability and speed is significantly better than what I was getting on the stock (decrypted/rooted) Nextbook. I had used Greenify in the past with the stock "rom" but that did little to mitigate the memory leak--it is 100% fixed in the iView's Android 5.1.1 "rom."
[Miscellaneous Android Development] vampirefo:
I do have camera working, working on other.
[Miscellaneous Android Development] Startrek852:
I might have a fix for all of the cons. Do you want to test it?
[Miscellaneous Android Development] vampirefo:
Have you tested your fixes, yourself?
[Miscellaneous Android Development] Startrek852:
No, I haven't. I don't have a working tablet to test them on.

[Miscellaneous Android Development] freddy999:
That is great news! What was the issue?
[Miscellaneous Android Development] vampirefo:
Swapping out files, I may have rotation working, will test more, so far screen rotates, will give it some more time.

I am not going to lock screen, so over the day I can see if a problem with rotation happens.
[Miscellaneous Android Development] freddy999:
I've beat the TWRP backup file you posted to death. It appears that the only issues with the ROM itself are, as you know, the rotation, the audio and the camera. everything else seems perfect. I did have two other problems but it was ancillary to the ROM, not really part of the ROM itself. The Facebook APK and the Twitter APK are missing, and that is a non issue to me as I use neither. But when the playstore tried to upgrade the bad install (facebook), the tablet crashed every time part way through the install. I assume the Twitter would have had the same problem. I simply disabled the programs and manually deleted them. The second was when I replaced the boot animation, the first attempt worked fine but the second one caused a boot loop. I do not know why, the screen resolutions of the images were correct and the same in both sets, just a bit odd. It might be related to the file size as the second was larger.

Beyond those minor things I think you have a real winner. The AcTuTu is great, and the quadrant score is insane. No lags, no hicups and it seems rock solid!

Oh, I did have a slight issue with the stepping of the processor speed after a deep sleep, but like you I use no frills CPU control and set to ondemand /noop the issue is non-existent.
[Miscellaneous Android Development] vampirefo:
Facebook app is included updates and works just fine for me, Twitter app included, updated just fine, I don't use it though.

Not sure about audio problem, I really only listen to headset, I may skip this, as I can't think of what the cause might be, sound just being low.

Nothing to track down, no sound would show an error, low sound shows nothing, cause nothing as far as tablet is concerned is wrong.

Real odd you not having Facebook app, cause it's installed, I use that app a lot, using it now on i708q tablet.

If you have a rooted file manager navigate to system/priv-app/Facebook

You should see Facebook app.
[Miscellaneous Android Development] Startrek852:
OMG THANK YOU!!! I finally got the tablet working again!! Now I'm going to flash the i708Q rom, but I'm confused as to which one to use, the TWRP backup or the zip file.
[Miscellaneous Android Development] vampirefo:
Either, the zip you extract and use fastboot to flash, it includes Linux and windows scripts, or hand type them.

The twrp backup is just that a backup, use twrp to restore, not your twrp lol, as it caused you problems, use one of mine.
[Miscellaneous Android Development] Startrek852:
OK Thanks. Do you think you can help me figure out why my TWRP won't boot?
