It does not really matter how you flash If TWRP is already installed then just flash the boot.img and userdata.img or all together.

Remember your userdata will have already been encrypted by the stock boot.img so it needs to be wiped as we can not un-encrypt it.

The custom boot.img will not encrypt the New userdata so TWRP will be able to read it without issue. :fingers-crossed:

You will have to go through the whole setup again updating apps, contacts, etc etc. :(

Hope that makes sense :laugh:
[Android General] zMILWAUKEE:
It made perfect sense, but unfortunately TWRP 3.0 did not work. It booted into recovery just fine, but would only reboot back into recovery. So now gotta wait on a 6.0 TWRP build. Or get my Linux machine up and running again and port one, or at least put few hours in of banging my head and trying it myself.

Could you use adb or SPFT?

Does the Lenovo MM ROM appear to be stable?

Sent from my Lenovo TAB 2 A10-70F
[Android General] bigrammy:
Try this one I just swapped the LP kernel for the MM kernel as sometimes that's enough.

MM-TWRP-6.0-kernel

EDIT: I just realised I patched the 2.8.7.0 LP rather than the 3.0.0 it should still work though. :fingers-crossed:
[Android General] zMILWAUKEE:
Yeah no dice so far. Thats ok though, this 6.0 is so minimal in the data footprint i have no real need for root or custom recovery. I think out of all the stock apps there is only 4 i want to get rid of, and disabling them in the stock app manager is just fine. Thanks for trying though.
[Android General] bigrammy:
OK It was worth a try anyway. I will flash the ROM when I get a chance (It's the wife's tablet :rolleyes: ) and see whats going on.
[Android General] peterpao:
Ok, no problem. Tell me how to do it? I'm a novice on Android...
[Android General] Tzul:
[MENTION=922438]peterpao[/MENTION]

First, you need the "MediaTek SmartPhone Flash Tool" (SPFT). You can download it here (latest version, v5.1640 at the moment, Windows or Linux... I'll assume you use Windows).

This program works with almost all Android phones and tablets that use MediaTek chips, not just this tablet. It can "download" (flash) firmware images onto your tablet, and also "readback" the current firmware from your tablet to the PC. We'll do the latter.

After downloading and unzipping, find the "option.ini" file in the SPFT folder, open it with a text editor, and change "ShowByScatter=false" at the end to "ShowByScatter=true". Save the changes and close the file.

The SPFT requires a special USB driver to communicate with the tablet. You can get it here. If you're using Windows 8 or 10, it's very easy to install: just unzip the file, right-click the file "CDC\cdc-acm.inf" and choose "install". For Windows 7, read the readme.

Finally, you need a "scatter file". It's a text file that tells the SPFT details about the partition layout of your tablet. This file should work.

Now you can run the SPFT (flash_tool.exe). It opens at the "Download" tab, where you need to click the "Scatter-loading" button to load the scatter file.

Then click the "Readback" tab. You should see a list of partitions, like this.

Click the checkboxes of the following partitions:

preloader, proinfo, nvram, lk, boot, recovery, secro, logo, tee1, tee2, system

You can select more partitions, if you like, but these are the most important ones. Note that proinfo and nvram contain your tablet's unique serial number and MAC addresses, therefore you should not share them with us, but it's good if you keep a backup of them on your PC.

As you can see, the partitions you selected will by default be stored in the SPFT folder as "ROM_0", "ROM_1", "ROM_2", etc. You can change the filenames by double-clicking on them, or you can keep the default names and rename them later, after the readback.

Once you've set everything up, click the "Read Back" button, power down your tablet (not just standby, turn if off completely), and connect it to the PC with USB.

After a few seconds, the SPFT should detect the tablet and start making the backup/readback.

If nothing happens, then let me know.

If it worked, then it would be great if you could share the following files with us:

preloader, lk, boot, recovery, secro, logo, tee1, tee2, system

It doesn't matter if they are still named "ROM_0" etc., I can figure out which is which.

Here's a little summary about how to use the SPFT (you can largely ignore the first image, because it's for flashing).

And here's an explanation if you're interested in the purpose of these files/partitions.
[Android General] Mika:
Okay installed MM on non rooted A10-70F with SPFT looks good for now.

Thanks zMILWAUKEE!
[Android General] supaet:
there's some strange issue mm rom:

the sleep function does not seem to work, the tablet stays awake all the time even the screen is off. I guess there is no doze mode? the standby battery life is terrible unless you use the schedule on/schedule off feature

holding the home button still brings up the google shortcut like it was in lp, can't seem to use the screen search on tab feature for mm.

[Android General] zMILWAUKEE:
Try to do a factory data reset, that should fix the sleep mode. Ive been on MM for two days now and did not have that issue. Alot of people here in this forum overlook doing a factory reset after either doing an OTA or a SPFT flash. If you notice in the stock system update app it tells you to do a data reset after each update. Well that also applies to any flash you perform. For some reason, on our tablet it keeps residual data that sometimes conflicts with a new update or flash. So just try to reflash and after the desktop loads just go into settings and do a data reset. The only issue ive had so far is the tablet telling me my Samsung Evo sd card was incompatable or the r/w speeds were to slow. But that was after a fresh flash and a reset fixed that issue everytime.

---------- Post added at 07:40 AM ---------- Previous post was at 07:36 AM ----------

for 100 bucks not bad, but ive read up on that tablet and they realy took steps backwards on that one. for a few more get a new or newer yoga tab. way more bang for the buck, and built alot better.

TWRP For 6.0

SAVE ANY IMPORTANT FILES AS THIS WILL FACTORY RESET THE TABLET......Here is a working boot.img and TWRP 3.0 for MM. Flash using SPFT as normal, after loading scatter both the boot and recovery boxes should already be checked, flash, and as we all know by now when flash is done boot into twrp right away. DO NOT install su.zip just. First you just need to reboot the device as normal. Then after tab boots up turn off boot into TWRP, press wipe do not swipe, and press format, type yes, let twrp do its thing, there will be a bunch of errors, ignore them and just press the reboot system option. http://www.mediafire.com/file/s2nfv8m2s6yars5/6.0_TWRP.7z

---------- Post added at 10:35 AM ---------- Previous post was at 10:32 AM ----------

One more thing, after boot you will see #SU in the app drawer, might work might not, just be on the safe side and flash the su zip with twrp.
[Android General] chris5s:
Thanks for this :good:

It's maybe an error on my part, but I get "BROM error ... Obtain DRAM failed... Check your load matches to your target which is to be downloaded" from SPFT when trying to flash. Have successfully used SPFT on this PC previously, not sure why it's chucking out that error...

Peace.
[Android General] zMILWAUKEE:
OK give me 10 minutes, I'll check it out. In the meantime try running soft as admin and see if that helps.

[Android General] chris5s:
You dancer! That did the trick.

After installing, booting into recovery, rebooting to system, do we then boot back into recovery, go to wipe - format data, then install supersu?

Peace.
[Android General] zMILWAUKEE:
I just reflashed it myself and cant get the same error, what SPFT version are you using, im using 5.1640 and running as admin. works fine on my side.

---------- Post added at 12:06 PM ---------- Previous post was at 11:59 AM ----------

yup, after the first flash make sure you boot into recovery first, then reboot the system power off then reboot to recovery, then in the wipe tab click Format Data, it will tell you to type yes, type yes and click the blue check mark in the bottom right corner. it will come up with a bunch of errors just ignore. when thats done click reboot system. your done.the first boot will take about 10 minutes. Im not sure if the su app in the app drawer works right away cause i rebooted and flashed the su.zip. but im about to find out in a few minutes as i reflashed just to make sure my instructions were correct.
[Android General] chris5s:
Thanks, just waiting for 1st boot to complete.

Will see if supersu works, if not will flash the zip.

Thanks man!
[Android General] zMILWAUKEE:
One quick tip, you can format your sd card for internal storage through settings, storage & usb, click on your sd card and in the upper right corner tap the three dot menu, the option is there, it looks like it gets stuck at 20% but it dont, it just takes a few minutes.
[Android General] chris5s:
I didn't have su app in the app drawer after fisrt boot, went back into twrp and installed the su.zip which seemed to work although the boot after that was a bit weird. Anyway, I have root - tested with ES File Explorer Pro, gained root and deleting system crap as I speak lol.

Thanks again!

Peace

---------- Post added at 10:43 AM ---------- Previous post was at 10:37 AM ----------

Thanks, yes, I'm familiar with that from MM on my mobile. On first boot with this tab you also get a notification that the sdcard has been detected and the option to use as internal or external storage :good:
[Android General] chris5s:

Today I received the Update 0123. It always gets an error trying to update.

Is there already a way to get this update to work?

And how safe is it to use that MM provided here? Will there be updates for it when I flash it?

I have the F Version of the A10-70 Tab 2
[Android General] chris5s:
No.

Perfectly "safe". Can't predict future updates tho. Take a backup and give it a try, everything works.

Peace.
[Android General] zMILWAUKEE:
Don't count any more updates from Lenovo, look what we had to do to get this. (MM) I think I found a leaked version that shouldn't be out yet..
[Android General] _Kurosu_:
Hi, for some reason, SPFT 5.1640 didn't allow me to tick recovery. Maybe a change in GUI design (an unobvious one), so I went back to 5.1620, which worked as described in the OP.

Regarding Update 0123 / 160921, I did have to factory reset after applying the update, coming from stock 0122 (no twrp/root installed).

Also nice to see that this tablet can do 1080p HEVC/VP9 in hardware!
[Android General] bigrammy:
I don't think the MM is in anyway official.

The boot.img uses the very old Mediatek boot.img format and looking through the init.rc's the is no mention/comment's for MM any place which there is in all the other official 6.0 Mediatek boot.img's I have looked at.

Also the kernel it's self seems very small compared to other Mediatek MM kernels. :confused:

I have seen 6.0 on cheap copy Tablets and mobiles which are not true MM kernels but they do work fine and are generally very fast just like this one but I am unsure as to their limitations which I am sure there must be.. :eek:
[Android General] Trainingwheels:
Do you know if there is a CyanogenMod version for the A10-70f?
[Android General] supaet:
well I did a factory reset, and then flashed the twrp and formatted data to get rid of the encryption, did first boot, and then use twrp to factory reset again, but the tablet still doesn't want to sleep. I can tell on the battery summery as the awake is always green.
[Android General] King Mustard:
Can I restore the stock recovery without having to flash the entire stock ROM?
[Android General] chris5s:
Yes :good:

---------- Post added at 12:11 PM ---------- Previous post was at 12:08 PM ----------

The native battery usage reporting in settings isn't always accurate, but have you tried setting location to device only (GPS) instead of high accuracy (WiFi, GPS, mobile data)? It may help.

Otherwise let the ROM settle in, give it a couple of charge cycles and see if its any better...
[Android General] King Mustard:
I have TWRP.

How can I flash this 7z?
[Android General] zMILWAUKEE:
Extract the 7z folder and you will get the SPFT flash files, just follow instructions in post #1537. And make sure you run flash tool as admin to avoid errors.

No but the BlissPop rom mentioned in this thread is CM based, Lolipop..
[Android General] supaet:
ok I will try and turn off location and see how it goes.

could it also be that the tab is trying to search for cell signals because the rom is designed for tablets with sim cards. is there any system/apps that we can delete/freeze to turn all the cellular stuff off?

I'm also not able to turn on airplane mode, that toggle is grayed out.
[Android General] zMILWAUKEE:
Without a sim card in it won't search for a network. And as far as apps delete any you see that are related the phone, I.e. incallui.apk and any with the blue phone image, or just go ham and delete what ever app you think has to deal with the cell network. Any thing goes wrong reflash, just go one app at a time and after each successful reboot write down the apps you deleted so in case you screw it up you already know which ones are safe to remove.
[Android General] supaet:
well, I tried everything, turned off scanning, removed phone/data apk, turned off wifi, turned off location (I cannot enable airplane mode, toggle is grayed out)

I tried to use trickster mod and kernel settings app to change cpu governor, but the cpu simply will not go to sleep no matter what.
[Android General] zMILWAUKEE:
you have me stumped. my tablet is not doing any of that. the last thing i could think to do is reboot into twrp and go to advanced wipe and wipe everything a few times and reflashing with SPFT. my tablet has been getting better (just slightly) battery life after a couple of days.
[Android General] supaet:
is your airplane mode toggle working?

I will try more wipes when there is a mm flashable zip available.

this doesn't really bother me that much, the boot time is less than 30 sec as I can just turn off tablet when I'm done using it.

by the way, everything works including mm xpose
[Android General] zMILWAUKEE:
my airplane mode just pulses,well the togle at least in the pull down tab. im guessing that since mine is the wifi only version and this rom was built for the sim card version, thats where the airplane mode bug is coming from. are you new to mediatek, cause i have never seen a flashable zip for our tablet, well at least not here in this thread anyways.
[Android General] supaet:
yeah, this is my only device with mediatek. I'm actually surprised that there is no flashable zip, the twrp is perfectly capable of writing to /system
[Android General] chris5s:
I seem to remember when MM first came out for phones, Google services were the worst culprit for keeping people's devices "awake"

Looking thru Settings - Apps, all my memory hogs are by Google, some being awake 100% of the time.

Have a Google around (no pun intended) and try some of the solutions out there. This version of MM may not be properly optimised...

Peace.

Edit I see you have xposed installed, there must be a module that will help? Amplify? I don't use xposed myself but there may be something...
[Android General] free4flight:
I have been notified since yesterday about the new update, have tried to update 4 times without success. I have not rooted this tablet, but am thinking bout doing that. I called Lenovo about the failure to update the OTA, no help. Am going to look into rooting this tablet although I have no real problems at all. But it is still on LL OS.

---------- Post added at 04:53 PM ---------- Previous post was at 04:37 PM ----------

Change lockscreen wallpaper with with MM 6.0?

Thanks to everyone who has supported the new MM update! It's like having a new tablet. I have my tablet configured just how I like it, except I cannot get the Lockscreen Wallpaper to change from the default canoes. When I use Gallery, and use the "Set picture as" option, I get a few options popup in a "Set as" window. I select Lock screen paper, then click "Save" in the upper left. I get a message "Setting lock screen paper" and the timer churns, then I get a message "Unfortunately, Gallery has stopped." I get a similar error when I hold down on the background and select the "Lockscreen Wallpaper" option. I select the image I want, then in the upper left of the screen I click on the "Set lock screen wallpaper." I get a message "Setting lock screen wallpaper please wait...". It churns forever until I have to bail out. I also tried with the Backgrounds app and couldn't change it. The default canoes in the lockscreen are nice, but I want to change them!
[Android General] zMILWAUKEE:
Airplane mode fixed on MM

Mine did the same thing today, ill try a few things and let you know how it goes.
[Android General] bigrammy:

Probably safer using "Firmware Upgrade" :good:
[Android General] zMILWAUKEE:
Yes your right Rammy....DO NOT DO WHAT I DID AND FORMAT+DOWNLOAD....now how do delete that reply...Im getting a little flash happy. But thats what i love about this chipset, it darn near unbrickable, so i have the courage to try whatever, that and my tablet is getting up there in age and i already have gotten way more use out of it than that $200 price tag should have gotten. Plus i need an excuse to get that YogaTab 3 Pro.
[Android General] Tzul:
That's a baaaad idea. I've probably explained it before, but here it is again:

"Download only" flashes the partitions you selected and does nothing else.

"Format All + Download" really does format (wipe, delete) everything, including the "hidden" partitions such as NVRAM. Do you want to lose your MAC addresses, IMEI, serial number (if present), etc.? No, you don't!

"Firmware Upgrade" is like "download only", but forces all regular (non-hidden) partitions to be flashed, and it updates the partition tables on the device with the settings (start address, size, name...) from the scatter file. Therefore, it's only necessary if the partitioning changed. Which it didn't for this tablet.
[Android General] rra1:
Lockscreen Wallpaper

I guess I will keep the canoe-themed lockscreen wallpaper unless/until someone comes up with a safer solution! Any other ideas? Is it a permissions issue with the lockscreen wallpaper graphic that doesn't allow overwriting?

mm have app permission options
[Android General] chris5s:
I actually had this problem on Lollipop too.

Fixed by editing build.prop but there doesn't seem to be the same fix with this build.

Stuck with the canoes too!

No one else have this "problem"?

Peace.
[Android General] philje123:
I have installed the MM rom and generally impressed.

But I also have the sleep problem. The tablet spends all it's time awake and never goes to deep sleep. Wakelock detector and Better battery stats aren't showing any wakelocks that match the time spent awake.

I have tried a factory reset and it's still the same even with no apps installed.

What phone related apps should I uninstall? And is there a way to get rid of the phone network strength bar at the top with an X through it?
[Android General] rra1:
Both launcher3 and gallery have storage permissions set to "on", so I guess that's not the problem. Thanks for the suggestion.
[Android General] chris5s:
Pull down the notification shade from the status bar and press and hold the Settings icon (cogwheel) for a couple of seconds. When you release it a toast message should pop up saying you have enabled System UI Tuner.

Go into Settings, down at the bottom there will be a new menu option called System UI Tuner (yep, no ****!) next to About Tablet.

Go into System UI Tuner, select Status Bar and near the bottom of the list de-select Mobile data - and anything else you don't want on the status bar!

Peace..

Edit - you can safely delete the telephony apps in priv-app, I think there's 3 of them (with the blue phone symbol) - hasn't adversely affected my tab, anyway :good:
[Android General] philje123:
Thanks for that. It did the trick.

But I'm stilling getting 100% awake time.

I've tried to roll back but can't it it into download mode. As soon as I connect the USB the tablet powers on and shows a charging screen with the time in the corner.
[Android General] supaet:
I think this 100% awake time is due to the kernel, I have tried many things, but the cpu does not go to sleep

I found a way to turn on airplane mode (hold power button and turn on there, as the toggle in systemui does not work)

but the tablet still does not sleep with airplane mode on, all connections/scanning off, google play services disabled.

I guess this is intended because the scheduled turn on/off feature is pretty rare among tablets.
[Android General] evilbunny1984:
I am currently attempting to follow these instructions in an attempt to unbrick a new A10-70F which I bought only two days ago.

One thing not mentioned, which I've learned the hard way: Unlike connecting a working phone/tablet to a PC to read/write the contents, the USB driver used here will not work (not even to the extent of recognising that a device is plugged in) unless the lead is connected directly to a port on the PC; a lead plugged in indirectly via a USB hub won't do the trick.
[Android General] Tzul:
[MENTION=7863344]evilbunny1984[/MENTION] I've used the SPFT for flashing and readback lots of times with the powered USB hub of my monitor. Works without problems for me. Whether an unpowered USB hub will work, I don't know. Anyway, a direct connection to the PC without hub is always better.
