Thanks for this. Unfortunately my second user seems to be locked out of a lot of things. For example I can't enable unknown sources. Is there anyway to make this second user have the same rights as the owner?

I also have to go into settings and user to switch users which isn't terrible, but on other tablets you can change from the lockscreen or the status bar. No idea why Lenovo didn't enable multiple users on this tablet....
[Android General] Len:
Hmm... So I have Lenovo A10-70L,

and here is my question

:

* I have rooted 4.4.4 (A10-70L_S000018_150423_ROW) used KingRoot (;/)

* Installed TWRP (recovery_twrp2870_for_A10-70L_Android4.img) using SPFT

How can I go to latest version (unless it's less stable than some other 5.*) and leave TWRP & root as it is right now?

Please correct me if I am wrong...

* Using TWRP install A10-70L_S000115_160119_ROW.zip

* Then using SPFT install recovery_twrp300_for_LenovoTab2A10-70L_Android5.img

* At the end... just flash SuperSU using TWRP

Also I have backup for all partitions

Is that enough to get back to stock / hide fact about rooting/flashing custom things on tablet?

And last question... I saw some custom ROMs on rus sites, like AOSP. They are safe?

Thanks in advance
[Android General] hackwerk:
Why use something insecure (closed source Chinese ****) and bloating, while we can update our tablet to newest versions, and then use the GREAT TWRP and the GREAT SuperSU to root!?

My advice: Flash factory, and totally clear all, and do that.
[Android General] Len:
I didn't know that is possible to flash TWRP without root so thats why =/

So I have to change recovery to stock, factory reset, update, flash twrp - profit!?
[Android General] clsA:
You should go back to post one, all the files you need to get lollipop are right their. And yes you can flash TWRP with TWRP just choose install/image
[Android General] Old faithful:
sorry, delete, I've been sick: (
[Android General] Len:
Okay, everything is fine right now:)

It was a bit shocking for me, cuz never had any device with unlocked bootloader.

But I have other question, mainly for devs... is there any flash / root counter flag?

Common one:

Also anyone got idea how custom roms are working?
[Android General] clsA:
I have no idea what your asking here

There are no Roms in the works for this tablet that I know of.
[Android General] Len:
Some devices have root/flash flags. They are used by service to check warranty void status.

Like user has flashed custom rom/recovery or root = warranty is void, he must pay for repairs.
[Android General] clsA:
To my knowledge their has been no discussion of that here. If it existed I'm sure someone would have mentioned it by now.
[MENTION=5919159]Tzul[/MENTION] would be the one to ask he has extensive knowledge of this device
[Android General] :
will they be a custom rom anytime soon?
[Android General] Coyo_Te:
damn, [MENTION=5919159]Tzul[/MENTION], you really went into detail there. thanks alot for the clarification, really appreciate it. will have to read it a few more times to grab all the info thats in your post :)

So it is as open as I initially hoped for. Thats awesome, in a way :) ofc it comes with more work.

So what I got from your answers is, that the Android system is basically a bit like custom Linux builds used to be or stil are. You have to/can compile your own kernel for your own specific hardware if you like. And after that you could build your OS around it. Kernel compiling wasnt too bad back 15 years ago, if you had a proper tutorial and not too messed up freaky hardware, ppl like me could do it.

But as you already stated, kernel and Android system arent the only parts that need to work. I have to read some more I guess. Will try to make the exfat and controller work in the meantime.

cheers again
[Android General] Len:
So.. those flags are same for untouched and touched (rooted, flashed etc...) ?

Right now I can see "warranty" set to "no" which can mean that there is no more warranty for this device :confused:

Thanks for reply!
[Android General] Tzul:
Yes, that's what hardcoded means.

Not in this case. Just because the new bootloader prints those values doesn't mean they're true. I could easily patch it to print the exact opposite...
[Android General] Len:
Got it. Sorry for doubling my questions, wanted to be sure.

Btw, first post is missing information about device status UNLOCKED.

In my opinion, it's needed (eg. I have first rooted to backup my partitions -_-)

Hope for some custom rom in... some time ;)

Stock is cut as ****. Not even chance for customizing quick settings panel...
[Android General] maris__:
You can tweak the quicksetting with the xposed modul GravityBox.

Best, maris
[Android General] Tzul:
[MENTION=3270510]Len[/MENTION] Like I said elsewhere, I've never seen a locked Android device based on a MediaTek chip (which doesn't mean it's impossible... just rare). You can read and write the entire flash memory with the SPFT, even before running the bootloader/recovery/Android for the very first time. But I get that many people don't know that, so maybe suhridkhan could mention in the first post that this tablet is "unlocked".

If you want to customize the quick settings tiles, you can use Xposed + GravityBox. Because of these great tools, the necessity for custom firmwares has decreased quite a bit.
[Android General] Len:
Yeah I know it right now. Should be mentioned in first post thou :)

Thanks for hint about GravityBox, I will try it.

Extra question, there is no zip-alight in stock rom, right? I have to create my own autostart script?
[Android General] Tzul:
[MENTION=3270510]Len[/MENTION] I guess you mean zipalign? There's no need to do that. The system apps are all aligned, and the Play Store doesn't even allow distribution of unaligned apps, as far as I know.

To make sure, I just tested all system apks of the latest firmware (A10-70F_S000121_151222_ROW), and actually found a single one that is not aligned: /system/priv-app/LenovoOta_ROW_V5.0.108.e0cd094.150828_all_rdv2key.apk - the OTA update app, not exactly performance critical. All other apks have the standard 4-byte alignment for uncompressed data.

Thank Heaven For Organized Resources!

I want thank EVERYONE who contributed to putting all these resources for this tablet in one place! My A10-70F has been rooted and running SuperSU for a while now. I also had the Carliv recovery but preferred TWRP for my devices. Thanks for the port!! Now everything in the house, but my HP, has been backed up with TWRP! I've achieved rooted peace!

My devices: HTC Desire 626s rooted stock 5.1

Lenovo Tab2 A10-70F rooted stock 4.4.4

LG F3 rooted custom rom. CM11 beta

I can't find a way to remove the digital clock from the lock screen. ?
[Android General] suhridkhan:
Yah, saw this earlier today. Not much of an update from our tablet. My only thought was, these are coming with Marshmallow installed. Lenovo is probably not gonna give us a marshmallow update. Wondering if those roms can somehow be ported to our device (thinking about the Mediatek chipset).

Honestly, I don't care about marshmallow update either. This tablet has been having rock solid performance with Lollipop (rooted and with xposed of course). For casual gaming and media device, I don't see myself upgrading to another tablet in the next one or two year.
[Android General] BoredDude:
Actually the tab 3 is kinda a step off in my opinion, considering how good the tab 2 performs and costs. I also have a little bit of hope in developers so they can port 6.0 but is not necessary, I am quite happy with the current state of the device. With this announcement I am now even happier with the tab

I use my Tab2 for work only. I'm a night dispatcher for a roadside assistance company. (AAA towing, etc). Since I rooted & debloated, it boots up and runs much faster now. I do try to sleep at night but I don't always get lucky. I do get calls from the police Dept's for accident towing. I can tell you, this tablet boots up faster than my brain does from a cold, dead, sleep! LOL. I use Apex Launcher Pro, and park everything I need for work on the third home screen. My Recent Apps button brings up my workbook in a split second! A must have feature when I have the State Police on the phone @ 3am!! I have an external Bluetooth keyboard that has issues. Every now & then, it times out. I have Xposed w/ Disable full screen keyboard module in it. That keeps Google Keyboard from taking up most of the worksheet in Landscape view mode. (A real problem with all us spreadsheet/keyboard users). I've had a few issues with OTG plug ins. Still looking for the "ultimate" keyboard! I would love feedback on the Bluetooth timeout / OTG plug in issues.

I use Windows 7 Themes downloaded from microsoft.com. I made a folder in my Pictures folder named Windows Themes to download in to. When finished, use 7zip to extract the pics. Put those pics in a new folder, Wallpapers. You can use those for your lockscreen in Win10. I copied that folder to my sdcard, and use those for this tablet. the aspect ratio is perfect for this tablet as they are made for large flat screen displays. Beautiful & Free!
[Android General] Coyo_Te:
Are there any folders hidden in common fileexplorers? like I read here and there that one should push a certain *.ko file to system/lib/modules/ but that folder doesnt exist on my tablet. at least its not shown. was it used in kitkat and is obsolete in lollipop?
[Android General] Tzul:
[MENTION=7184758]charlestek[/MENTION] Thanks for the info. The Tab 3 looks nice, but it's only a minor upgrade. I don't see any great new connectivity options (compared to the Tab 2 A10-70L).

[MENTION=5142831]loner.[/MENTION] The Tab 2 A10-70 uses an ARM Cortex-A53 quadcore CPU. If the Tab 3 simply uses a Cortex-A57, it would easily be a bit faster due to its better feature set (3-wide superscalar pipeline, out of order execution, ...), despite the slightly lower clock frequency. If the mentioned clock frequency is correct at all. The Tab 2 was advertised as 1.5 GHz in some places, but ended up being 1.69 GHz.

[MENTION=4717484]nannycrick[/MENTION] Welcome. Sounds like you have an interesting use case for the tablet. I haven't tried any bluetooth gadgets with mine yet. GravityBox should also have an option that disables the fullscreen keyboard, so maybe you don't need a separate Xposed module for that, if you're already using GravityBox.

I like to use Hacker's keyboard sometimes (especially when using a terminal - tab and arrow keys are important there). It has a setting that should prevent the "soft keyboard" from being displayed on screen at all when a hardware keyboard is active.

[MENTION=7291313]Coyo_Te[/MENTION] In Linux, files and folders starting with "." are considered hidden. The one you mentioned isn't, it simply doesn't exist. Sounds like you want to add a kernel module. I don't know much about these, but I think they need to be tailored to the exact kernel version you want to use them with... And in theory, they can be located anywhere, because they need to be activated/installed by a dedicated command (insmod or modprobe). But /system/lib/modules is the usual Android directory for them. Let us know how it goes.
[Android General] charlestek:
[MENTION=5919159]Tzul[/MENTION]

Yeah, you're correct, I was reading too much of the marketing verbiage, they made it sound like there are additional connectors on the Tab 3 10 for Business, when in reality they were talking about using USB OTG adapters. BTW, how much Usb OTG does the Tab 2 support?
[Android General] Coyo_Te:
after searchin and reading around on the forums, so atm it seems that this insmod isnt workin for everbody even though used with the correct kernel version. the thread it was mentioned in is like almost 4 yrs old now so i doubt its stil relevant at all. i cant find any xpad.ko for newer kernel version so i guess the whole method is kinda obsolete.

i found out thought that the wireless receiver might be mistaken for a charger by the system. the usb device info doesnt recognize the product but at least microsoft as vendor. will see what comes next. still digging.

Tab 3 10 Business with Bluetooth keyboard/kickstand

http://www.androidpolice.com/2016/02/21/lenovos-mwc-2016-lineup-aims-for-the-low-end-with-cheap-vibe-k5-phones-and-tab3-tablets/

I have the Lenovo OEM bluetooth keyboard/cover for the Tab2, (http://shop.lenovo.com/gb/en/itemdetails/888016645/460/60AC6A0372B14F5BA7B12F1FF88E33C7) but it is a pain as it can be only used as a cover with the bare tab (no case), and I really have to have a leather case on the Tab 2 so I don't damage it. So the Tab 3 A10 will have a more integrated kickstand keyboard available. More interesting are also the Lenovo mid range cell phones.

The largest entry in the Tab3 series is also the most interesting, if only because the Tab3 10 gets a "Business" suffix bolted onto the name. The 10.1" screen is 1920x1200 with dual speakers and Gorilla Glass, and customers can add on an external Bluetooth keyboard that comes with a kickstand - hence the "Business" moniker. The body is allegedly dust-proof and splash-proof as well. The cameras have been upgraded to 8MP on the rear and 3MP on the front, RAM is 2 or 3GB, and storage is bumped to 32 or 64 gigs plus a MicroSD card slot. But that's about where the "premium" features end - it still uses a MediaTek 1.3GHz quad-core processor, and strangely LTE is limited to a single SIM card. The battery is 7000mAh, and it's also running Android 6.0. The Tab3 10 Business will be sold for $199 for the Wi-Fi version, $249 for the 2GB LTE version, and $299 for the 3GB LTE version, starting in June. There's no mention of price for the keyboard accessory.

For parents worried about the effects of blue light from device screens on young eyes, the TAB3 7 and TAB3 8 come with Adaptive Display technology that can filter out blue light. The screen can adjust the tablet's visuals and sounds based on what the user is looking at on the screen. It also adjusts for brightness and color, detecting the ambient lighting of the surrounding environment with the help of sensors.

Looks like a sort of f.lux for android.

I'm sure Tzul would be thrilled by the ambient light compensation that the Tab37&8 have...

[MENTION=5919159]Tzul[/MENTION] lenovo hasn't specified if the MediaTek chipset has been updated.

Lenovo Tab3 10

Finally, the Tab 3 10 is the most interesting of the lot offering a 10.1" 1080p display with Gorilla Glass and dual-speakers. Lenovo hasn't specified if the MediaTek chipset has been updated, but the CPU clock is up to 1.3GHz. RAM is also up and depending on the model is either 2GB or 3GB.
[Android General] Tzul:
You can connect a hub to connect multiple USB devices at once. It best be a powered hub, so that the tablet doesn't have to power the devices (there's undoubtedly a current limit for OTG power). USB controllers support a certain number of "endpoints", theoretically up to 127, or even 255. In practice, the number is often much lower, e.g. 32. Each USB device consumes at least one endpoint, but possibly two or more.

Anyway, I've once connected two USB memory sticks plus a mouse to my tablet, via USB hub, and everything worked.

Yes, very. ;)

They also haven't specified it's the same. If the specified CPU frequency is correct (like I said, it might be subject to change), then it's unlikely that it's the exact same chip.

Also, I was referring to your exchange with charlestek:

"Just because the clock speed is lower doesn't mean the system speed is going to be slower."

-"That's usually a given, unless the chip set is a revolutionary new design."

That's wrong, unless you consider some CPU features which have been around for ages "revolutionary new design". Like I said, details like improved pipeline, out of order execution, improved branch prediction, larger cache, can make a CPU faster despite a lower clock frequency. And there are existing ARM Cortex CPU designs that have these improvements over our A53. Anyway, we'll have to wait and see what CPU the Tab 3 will end up having.
[Android General] charlestek:
Yeah, I'm sure the tablet is not designed to source Usb 2.0 current like a PC, the only powered hub I have is Usb 3.0, which theoretically should be

backward compatible minus the extra pins. I'm sure I can pick up a powered Usb 2.0 hub cheaply though.

[MENTION=5919159]Tzul[/MENTION]

Hmm, I'm very surprised that you can use a mouse on the tablet, it would be cool to have a keyboard with a touchpad, or even use a mouse,

I'm not actually a big fan of touch except for the use case of portability, which is more important on a smaller smart phone screen.

I assume you used a generic usb mouse, and that there must be some kind of generic mouse driver. I have all kinds of logitech mice hanging around, but the

only one that is usb is a G700s, and I have some cheap Microsoft usb mouse sitting around.

Usb OTG with charging?

http://www.scientificcomputing.com/blogs/2015/01/go-fascinating-facts-about-usb-otg

" A more accurate way is to actually test your device using one of the various USB apps in the Google Play store, such as USB Host Diagnostics from Chainfire. Note that, to complete testing, you frequently must already have a USB OTG cable on hand. "

Good article, apparently some devices support simultaneous charging while hosting the port. Unclear as to whether you can only use one client device at a time or not.

Found only one device that includes a power supply so you don't have to power the hub off another usb 3 device for a power source.

You can even use a Bluetooth mouse, then you don't have to deal with wires.

Mouse support has existed in Android for a long time. A few apps can actually make good use of it (but most don't). Here's a nice article about it.

Like I said, you can definitely attach multiple USB clients.

According to some quick tests I did, this tablet does not support simultaneous charging with OTG. You can either charge, or have OTG active, but not both at the same time.

The power management IC in my Tab 2 A10-70F appears to be a Texas Instruments bq24296. Datasheet is freely available. According to it, this PMIC has "USB OTG with Adjustable Output 4.55 V to 5.5 V at 1 A or 1.5 A". That means it draws either up to 1 A or up to 1.5 A of current from the battery to feed USB OTG devices, depending on a register setting. That's good, because that's enough for several USB devices or a single power-hungry one. I think it even defaults to 1.5 A, but I'm not sure. Anyway, if I'm reading the datasheet right, it confirms that simultaneous charging with OTG is not supported (page 34: "The CHG_CONFIG and OTG_CONFIG bits cannot be set at the same time", "OTG_CONFIG would over-ride Charge Enable Function in CHG_CONFIG").

Thanks for the details. I narrowed choice of hubs to two: http://www.amazon.com/Support-iKross-Bus-Powered-Micro-USB-Function/dp/B00TGDBS6M/ But you would have to plug the large Usb connector apparently into a USB (3) power source

and this:

http://www.amazon.com/EZOPower-Micro-USB-Charging-Docking-Station/dp/B00UCLUHZU which again requires an external Usb power source
[Android General] Tzul:
[MENTION=7184758]charlestek[/MENTION] Nice choices.

I have one of these, small and cheap. Three USB ports, plus a micro one for the power supply. The charge/OTG switch will toggle the OTG pin and therefore determine whether the tablet will "see" the attached USB devices or not. Regardless of the switch setting, a connected micro USB power supply will power the USB devices. But only when it's set to "charge" will it charge the tablet (because as stated before, this tablet doesn't support both simultaneously). And the charging current is limited to a slow 500 mA, probably because the switch doesn't also short-circuit the D+ & D- pins, meaning the tablet won't recognize it as dedicated charger.
[Android General] worm9110:
I hope the devs here continue their work even with the TAB 3 around the corner. I really like my Lenovo Tab 2 A10-70 and I hope to get new/fresh updates for it.
[Android General] charlestek:
Unfortunately with the new Tab 3 coming out with Marshamallow, it is unlikely Lenovo will provide any updates past Lollipop with the Tab 2 A10 at end of life in June. I'm sure everything about updates is budgeted according to a support plan. It baffles me when users complain and have no clue that everything about a device revolves around budget and money and a planned life, like the company will update a device two or 3 operating systems later. I know with my Thinkpad laptop, updates tend to continue, but I paid a premium price for the device.

However, since it will be until June when the new device comes out, I guess there is always the possibility.

[Android General] nannycrick:
For my own preference, I bought a mini Bluetooth keyboard to use with my Tab2. This tablet replaced an RCA tablet with dedicated keyboard that didn't last six months. I'm still trying to get them to warranty it after it crashed due to a poorly written update (Junk!) My Onm 10"Bluetooth keyboard "times" out even though I have the settings on "never sleep". Google keyboard is the best for this tablet as it will allow for " sizing" adjustment if you install the Disable Full screen Keyboard Module in Xposed. The landscape view keyboard, after module install, only takes up about a third of your view! A big help when working with a spreadsheet! Other keyboards have their own UI settings and still take up too much screen space in landscape. Google keyboard is a "native android" app and tends to adapt better. Still looking for the right adapter to connect between the Tab2 & Bluetooth w/ micro usb port keyboard. I guess I'm old skool! Maybe I just have to get used to software instead of hardware! I still prefer a tablet for work. Especially when I'm in the impound yard @ 3am collecting info from a wrecked auto. The 10" form is perfect!

Thanks for the tip on Gravity Box. I haven't used it on this device yet. I'll keep it in mind!!
