For sure there must be a way to go back to Android, I just don't know it yet :). I think that Windows 10 might be able to use the generic drivers for touch and wifi, unfortunately I cannot check it...
[MeMO Pad 7 General] Tumist:
Can you make a guide for installing Windows 10. I could give it a try, but i dunno how.
[MeMO Pad 7 General] Ruwin:
I wouldn't make a guide until I can figure out how to get back to Android, if it is possible without JTAG. Also I would rather advise you in private if you really want to test, because a guide to install Windows and not be able to use it properly doesn't make sense. Do I make any sense?

In other news, I managed to install Ubuntu, the touchscreen works but not the wifi and other sensors - as expected. Maybe with network access, the other may be obtained, but with no wifi, Ubuntu is useless.
[MeMO Pad 7 General] Leonidas2508:
I'd LOVE to see windows 8/10 running on this tablet if you can please share how you did it
[MeMO Pad 7 General] en4ovix:
you can use Ethernet usb card for ubuntu to gain network access
[MeMO Pad 7 General] jerbear294:
While you're at it do you think you'd be able to experiment with Android-x86? They've made a release contestant for Android 5.1, and if that can boot installing a custom rom could be as easy as wiping partitions and replacing it with that. The only limitations I could think of are no fastboot or recovery. Recovery could be replaced with a full drive clone/restore for nandroids or just reinstalling Android-x86 for OTA updates.

Do you think you could also boot up a live USB or Win7/8.1/10 and run Unknown Device Identifier to see if it pulls up any more information about the sensors that aren't detected? If we can get the model number of those finding drivers would be a whole lot easier for Windows, Android and Linux.

That would completely ruin the portability of the tablet. It's fine for testing purposes like this but later on that's not going to cut it.
[MeMO Pad 7 General] Ruwin:
I just installed android x86, the latest 5.1. It works but without wireless. The battery is also not recognized, but it's there. I've also encountered some crashes and reboots. Tomorrow I'll install a 4.4 version for Asus, maybe the right drivers will be there.

---------- Post added at 09:56 PM ---------- Previous post was at 09:53 PM ----------

I actually didn't install Windows as the setup blocks the installation because the storage is to small. A wimboot installation would be possible but I'll have to have some spare hours to try that.
[MeMO Pad 7 General] en4ovix:
Just to find if there is a wifi driver, not permanent...
[MeMO Pad 7 General] famac!:
Did a factory reset and it made no difference. Still getting reboots. Looks like i have to look into rooting and loading a ROM on it for improved stability.
[MeMO Pad 7 General] jerbear294:
I'll take AOSP 4.4 with root and Xposed over ASUS's bloated mess of a skin any day.

I wouldn't be too confident that the drivers are there though- if they're not included in Linux odds are they're not in Android-x86 to begin with. If the drivers were to be found it wouldn't be that difficult to make a custom kernel with the drivers patched in (assuming it's the same process as making a custom Linux kernel, I haven't done any Android building in a while)
[MeMO Pad 7 General] social-design-concepts:
Personally I'm not a fan of Android-x86 granted I haven't played with it in a couple of years, the devs care more about traditional PC hardware than mobile devices.

android-ia used to be awesome but not so much now hopefully Intel moves the IRDA source their with android 6 as it be nice to see support for actual tablet hardware rather than a development board.

ConsoleOS looks promising but they have yet to open up their source to the public.

Really wish I could find some documentation / source on the android boot mode of uefi it's rather annoying that even with secure boot disabled when boot mode is set to android instead of windows 8.x the efi app still has to be signed by the manufacturer.
[MeMO Pad 7 General] jerbear294:
Android-x86 was the first thing that popped into mind, and that's why I mentioned it.

I've never heard of Android-IA and I supposed there's a reason for that.

I was looking at ConsoleOS earlier, it does indeed look promising, and is by far the best pick. Hopefully the source is opened soon so drivers can be added, then it's off to the races.
[MeMO Pad 7 General] Ruwin:
Most probably Asus will unlock the bootloader until I will have time to compile a kernel with the right drivers. But if that happens, then I think it won't be that difficult to write an efi app to boot Android. Anyway, I'll try and boot the Asus 4.4 to check the drivers. One step at a time :)
[MeMO Pad 7 General] jerbear294:
We're getting closer :D Thanks for taking the time to investigate all of this!

Our best bet is ConsoleOS but for that to work we need its source code, or at the very least the kernel source. While you're at it can you try booting that as well?
[MeMO Pad 7 General] lambdadroid:
I'm not sure if you will have much fun with any distribution of Android made for PCs (which Android-x86 and ConsoleOS are basically designed for, aren't they?), especially with the low amount of RAM in our tablet.
[MeMO Pad 7 General] jerbear294:
It's just Android ported over to the x86 architecture- they're not specifically designed for PC's (ESPECIALLY ConsoleOS)

Android-x86 also works pretty well on my friend's Windows tablet with similar specs to our tablet (Z3740 instead of Z3745 and 2 GB RAM) and considering the optimizations made in 5.0 it should run well regardless.

Android-x86's performance wouldn't be the best due to its hardware support, true, but ConsoleOS actually supports hardware acceleration so it would be a lot faster than ZenUI.
[MeMO Pad 7 General] Beaver_XT:
After .33 update search function in the media storage has disappeared. I mean magnifier button to choose ringtone for alarm clock is gone.

And I can't use other app to choose the song either. Has anyone got a solution for this?

I forgot to mention that dropping file in Ringtone folder doesn't work either.
[MeMO Pad 7 General] jerbear294:
No solution that I know of unfortunately.

Can somebody try booting Console OS on their MeMO? We might not need the kernel source if their driver support is good enough.
[MeMO Pad 7 General] Beaver_XT:
Thanks anyway, so that I know it's broken.

I got a workaround by freezing Desk Clock and Weather then install Google Clock instead. Now I can use ES File Explorer to choose the ringtone.
[MeMO Pad 7 General] MaDDaWg836:
i just tried to upgrade to .33 and during the install process i got Error! with a dead android. after a few reboots and messages saying something about no loader on E:./ it managed to find the os and load the old one.

Im rooted but never had an upgrade problem. im worried to do it again, but i actually dont see the upgrade message anymore, only a 1 near system update but nothing shows up.
[MeMO Pad 7 General] jerbear294:
I made a Nandroid of the latest update if you want to search this thread.
[MeMO Pad 7 General] MaDDaWg836:
Thanks for the backup, im getting it now.

One more thing, is this one rooted or would i have to reroot it? last time i used ZenFoneRootKit_20150528. not sure if it would still work or if there is a newer method i dont know about.

Thanks again.
[MeMO Pad 7 General] jerbear294:
I took the Nandroid from my brother's stock tablet, so it is not rooted. You can do so from the temporary TWRP needed to restore the backup.
[MeMO Pad 7 General] MaDDaWg836:
i have twrp 2.8.6.0. I do not see any option in there for rooting. could you possibly explain how to do it through twrp? i have looked around but couldnt find anything.
[MeMO Pad 7 General] spookmeister101:
Download the latest Supersu at https://download.chainfire.eu/396/SuperSU/UPDATE-SuperSU-v1.94.zip?retrieve_file=1 save it to your sdcard and install using twrp or cwm.
[MeMO Pad 7 General] MaDDaWg836:
Thank you for all the help guys!
[MeMO Pad 7 General] xristos2:
From yesterday my lovely tablet :P started showing wrong hour. I have it on automatic and nothing. A restart fixes the problem until I leave it for some hours then the same again. Any idea? Rooted and xposed . 24 version
[MeMO Pad 7 General] jerbear294:
That sounds like the clock drift issue ASUS supposedly fixed in that update (spoiler alert: they didn't)

ClockSync on the Play Store is kind of a solution, however clock-based apps like YouTube will still lag and stutter.

A temporary fix (at least on the older update) that I found was to power off the tablet, leave it off for 30 seconds, and power it back on. If the boot animation is slower than normal it didn't work, otherwise it should be fixed for a few days.

I haven't experienced it on the latest update, however, the catch is that Xposed doesn't work on the latest update and there's battery drain that can be fixed by freezing ASUS Services.

Xposed did update earlier, but that update apparently does not effect the 5.0 version. I'll have to try it anyways.
[MeMO Pad 7 General] artpopboy:
FIXED

hey guys, i opened it, disconect and connect the battery again, voilá! :laugh:

but this tablet is so so so slow...... any way or custom or based rom? anything to make this device more smooth! thank you
[MeMO Pad 7 General] jerbear294:
Unfortunately, no custom ROMs yet- however we are very, very close. We're able to wipe Android and replace it with Windows, Ubuntu or Android-x86 (and most likely ConsoleOS, which is Android-x86 on steroids, it's our best bet for a ROM but it hasn't been tested) and as soon as we can get the right drivers and inject it into the kernel we should have a stable enough custom ROM.

If your tablet is sluggish, update it- the latest update brings the speed up to where it should be with hardware like this. If your tablet won't update, I made a Nandroid of the latest update a while ago, just search this thread for it.
[MeMO Pad 7 General] artpopboy:

Unfortunately, I didn't manage to boot ConsoleOS. For some reason, as soon as the boot process starts, the screen goes black and nothing happens. Maybe my USB key is poorly written, I'll try again and see. If not, it's time to start rebuilding the Android partitions and try to restore fastboot.
[MeMO Pad 7 General] Ruwin:
Can anybody boot Linux from an USB and make a complete mmc backup? I could use one to restore my tablet so I can start over again :) Thanks!
[MeMO Pad 7 General] tim_h:
I am still experiencing very bad lags every now and then after updating system to v33 with the nandroid backup provided by [MENTION=5479482]jerbear294[/MENTION] - the system virtually comes to a halt in these cases. Is anybody else experiencing these issues? I will try to use Nova Launcher instead of Asus Launcher and see if this helps.

I could go back to v24 of which I have made a backup. But regular update to v33 is no longer possible for me because I had modified this version and not taken a backup. :(

Would using the file provided by [MENTION=6833678]cyandro[/MENTION] be an option to get a completely stock v33?

How would I do that. Go back to my modified v24 and then flash this zip update via temp TWRP? Will it work in spite of my modifications to v24 (in particular rooting)?
[MeMO Pad 7 General] jerbear294:
I would, the problem is I don't have a powered USB hub. Sorry about that.

Strange, try factory resetting.

That file will not work, at all. It's the reason people use the Nandroid to update instead of the zip, ASUS detects all the mods now unfortunately- and changing the updater-script to stop the detection has had mixed results. Sometimes it works, sometimes it doesn't.
[MeMO Pad 7 General] tim_h:
Could do. But then again, it should not be necessary, should it? When making the regular update from v24 to v33, no factory reset is needed.

Ok, thanks for the info, then I can save myself the hassle.

Is there a complete stock v24 nandroid backup out there, somewhere? Or could someone who is still on stock v24 without any modifications (no root, ...) make one with the temp TRWP? Then I and others who had modified v24 could restore that and take the regular update from there. In theory, it should not be necessary, but maybe there is something in the ASUS update from v24 to v33 that is not adequately reproduced by just restoring a v33 nandroid system image?
[MeMO Pad 7 General] Mis012:
To make a complete emmc backup you need just android terminal app, root, and free time. You can use dd command to copy it to a file :) btw. Writing this from my tablet (yes, I am baaaaaaaack I still can't believe it!) just disconect and reconnect the battery, and if I charged the tablet before doing it, I may not need to jump start it with my nokia 5310 baterry (this is the part I can't believe)
[MeMO Pad 7 General] jerbear294:
There's my issue [emoji14]

Your tablet is back? :D You had to jump it through a Nokia tablet of all things? That's not something you see every day.
[MeMO Pad 7 General] artpopboy:
where is supposed put the zip nandroid file? i've select restore, empty list...
[MeMO Pad 7 General] MaDDaWg836:
extract the zip contents to a folder and put that on the internal sd card of the phone.
[MeMO Pad 7 General] vesko2000:
I've been following your and other peoples' posts lately and I can't seem to understand how exactly are you booting from USB. AFAIK you boot to UEFI ( somehow ), so you need the LP update. You also need a powered USB hub cuz external USB power is disabled by default? Could someone explain the process of getting there, please? Also, is it reversable? Is Windows 10 bootable on the 16GB version? Does any Linux distro boot? Can you replace the stock Android with another OS ( read Ubuntu, Debian, Windows 10, Android-x86, Android-IA) ?
[MeMO Pad 7 General] Ruwin:
You need a powered USB hub to be able to use the UEFI, because you need to feed the mouse/keyboard somehow. With the hub connected, you can press F2 on the keyboard when the tablet boots (actually you gotta mash the key) so you get into UEFI. There you can boot from a USB with live Linux (or whatnot). You can of course install Linux on the tablet, or even Windows if you have at least 9 GB of storage, but that will wipe all Android stuff, and most probably even the efi bootloader, so it's a one way road so far. Also the lack of drivers makes the experience suck. You could get it back to Android, like I'm trying to do, but the manual path is tedious. Else, a mmc dd backup can solve this issue. But I thing it should be done from outside the Android OS because I don't think that all the mmc's partitions are visible from there.

---------- Post added at 11:11 AM ---------- Previous post was at 11:09 AM ----------

Are you sure you have access to all the mmc's content from the Android OS? In this case, yeah, that would do it. But I have the feeling that it would be best to make the mmc backup from outside the OS - from a live Linux or Gparted USB. And that, yes, requires a powered hub...
[MeMO Pad 7 General] therealprof:
That's not quite correct. USB OTG provides power, just not very much. Regular keyboards and USB sticks can be simply connected using an adapter but OTG might not provide enough juice for a passive hub and several devices, connecting just a keyboard to get into UEFI usually works just fine.
[MeMO Pad 7 General] Ruwin:
Well, it didn't work for me. I had to use the powered USB hub to be able to use mouse/keyboard. The USB power management is different when in UEFI. Maybe others might get away with using a OTG for keyboard in UEFI (though I can bet it won't work), but they will need a power hub for any additional USB devices.
[MeMO Pad 7 General] Mis012:
Yes I am sure. And bite copy doesn't care about partitions, it only cares about entire emmc. And that's what mmcblk0 represents.

And I would also like to know how to use keyboard without power supply in pre-boot stadium.
[MeMO Pad 7 General] Ruwin:
You cannot use the keyboard without a powered USB hub or a powered Y OTG cable at least. Not in UEFI. BUT, you can get a powered hub for as little as $10, and you'll make use of it all the time if you use a desktop - so it's not a bad deal.

---------- Post added at 12:31 PM ---------- Previous post was at 12:13 PM ----------

So I've just restored the tablet to it's original settings, with Android running and all that (cloned a friend's mmc - same tablet). The takeaway is that the best/easiest method to do a backup and a restore right now is using a live linux (or the tablet's own Android OS with Root and Terminal Emulator - thanks Mis012) and the holy dd command to create a mmc image, then restore it after you've totally messed up your device. The catch is that you need a powered USB hub and a live linux USB. So Android > Windows (kinda) > Ubuntu > Android again.
[MeMO Pad 7 General] MaDDaWg836:
anyone notice the .33 updates screwing the battery?

every since the update ive gotten **** battery life and weird things like clash of clans crashes a whole lot now. i might just go back to my older backup since this one blows.
[MeMO Pad 7 General] jerbear294:
Yeah, the battery's horrible now. Freezing ASUS Services helped a bit though.
[MeMO Pad 7 General] therealprof:
For me that helped a lot but frankly the battery performance of the me176c always sucked for me independently of the installed software. I also have the me572c which always was and still is worlds better despite being better in any measurable aspect.
[MeMO Pad 7 General] tim_h:
I also have miserable battery life on .33, even when freezing Asus Services. :(

Do you have a nandroid backup of stock (untouched) .24? If so, could you share it?
[MeMO Pad 7 General] MaDDaWg836:
well i backed up .24 and its rooted, i tried to reflash it with boot and system with twrp but it gets stuck at the asus logo. i can still make it access TWRP. would i have to reload all the way from .182 like the other thread says or is there a better way. i reflashed to the .33 for now it came back.
[MeMO Pad 7 General] rodrengo:

everytime ive had a bootloop when restoring i just restored the latest .33 unrooted flash and it comes back. your device should appear on your pc even on the asus logo so you can get into the temp TWRP

TWRP is capable of healthy formats, and if backup file includes all necessary files. Still formatting only /system wont hurt. But if you, somehow, cannot restore, then your system will be gone. Therefore, download the full firmware from Asus's support website for a backup position. Put it into your tablet and sd card. - Moreover, Restore option could wipe all necessary partitions by default, i am not sure though.)

Choose the file destination where you put [MENTION=5479482]jerbear294[/MENTION]'s backup.

Then choose "System image".

After restore maybe wipe /cache and /dalvik cache would be fine.

Meanwhile you can root as well.

run the launcher.bat with your device connected. type "ACCEPT" without quotes. then 2 for portrait mode. then T4 to enter the recovery. once in there you can go to file manager to transfer things. i forgot exactly where it is but just explore.

Something needs to be running really wrong for my/this tablet. I've disabled almost all ASUS things I don't need (even most of the services), yet the battery of my tablet is still draining a lot, even if it's just standby with nothing on it.

Any ideas? This is really annoying...
[MeMO Pad 7 General] jerbear294:
Don't worry. The stock ROM is terrible, buggy, and bloated. I hate it with a passion.

Why do I say don't worry? Battery drain won't be an issue soon, because this ROM won't be plaguing our devices for much longer... Something HUGE is coming.

I'm not allowed to go into specifics. What I will say is that an innovation is on the way. It's still being tested, but after it's proven a safe modification and it's made more permanent it will mark a new era for our tablet.

Soon...

[MeMO Pad 7 General] :
[MENTION=5479482]jerbear294[/MENTION] are you making an OS or is someone else making a ROM? It sounds like you know what's coming and it sounds like a custom rom and/or AOSP something
[MeMO Pad 7 General] Penguineh:
Hey All,

I have been a longtime lurker of this thread, myself having a memo pad :)

Rather than making a "rom", why don't we extract the drivers out of asus's android, copy them and install them along with android-x86?

This would make our tablet run a stock android, and get timely updates?

Cool stuff Jerbear, can't wait to see whats gonna happen :)
[MeMO Pad 7 General] rodrengo:
I'cant pass bootloop...asus mtp is not recognized by two pc
[MeMO Pad 7 General] jerbear294:
Not a ROM, but rather jumping over the last big hurdle needed to make one.

ASUS's kernel source with the drivers is out of date so the drivers can't be trusted. On top of that installing android-x86 requires the current bootloader be wiped and can only be installed with a powered USB hub. Plus it doesn't allow for things like CyanogenMod.
[MeMO Pad 7 General] Penguineh:
:fingers-crossed: This sounds awesome, yeah I've seen Asus's kernel files posted and it indeed looks like a bodge job to get going on android-x86.. but..

The tablet is based on Intel x86 compliant hardware, so android-x86 should run fine, so for those that have tested it: does wifi, bluetooth etc work with generic drivers? It is a Broadcom wifi chip right? I do see, though, that the touchscreen would be a problem and would probably need custom/asus drivers.

I think I have a reasonable idea of what you (and your team??) are making jerbear :). I won't publicly guess though!!

I have a dodgy memo pad that sometimes (usually when I mess with it) doesn't start up, only booting to a backlight turning on. I believe this is a motherboard issue, but my tablet was bought in Europe and the service/warranty doesn't apply here.. The UEFI/BIOS makes my tablet do this, but it's an easy fix! Just pop off the back and disconnect the battery for 20-30 mins. Weird huh? Hopefully what is to come doesn't weird out my tablet like that !!
[MeMO Pad 7 General] lambdadroid:
Did someone finally get a proper custom bootloader (fully) working? At least, that's what it sounds like :P

---------- Post added at 15:32 ---------- Previous post was at 15:30 ----------
