Just reporting back:

- Flashing Firmware+TWRP worked out of the box.

- Same installing SuperSU (2.65) and Xposed Framework from the bootloader (TWRP v5).

After some hours installing stuff etc, tho, I had the sick idea to activate AppSettings Xposed module (also freezed some services).

Couldn't reboot the tablet anymore (stuck on the first screen).

Had to boot to TWRP and wipe "data" (maybe that was a bit extreme). This did the trick and I could reboot again (from the start :'().

As reported before, colors are far less saturated. Also, turning off AAL from the Engineering app is very simple.

Too bad that the Settings app cannot be tinted "dark" (neither with HoloThemer).

I also removed a bunch of apps and freezed others through Titanium.

Fractured the lower right corner of my Tab2 today....don't ask! Grrrr! It still works but the fitted case & screen saver only helped so much!

Anyone got a parts tablet with a good display they want to sell?
[Android General] Old faithful:
What a bummer! but don't be shy to explain how it happened and show us the case you were using so we may avoid that ;) Mine fell from the top edge of the sofa, about two feet high, right on the corner but on on a carpeted floor, with absolutely no visible damage... Although I wouldn't try that on a hard floor, for sure!!!...

Perhaps the design of my case has something to do with it?
[Android General] nannycrick:
It slipped out of my hand as I was climbing out of my hubby's tow truck. It struck the pavement right on the corner! Still working so I can't complain. Found the replacement display online $40 USD. Now to get somebody to install it if I order it.

This happened a day after my computer desk collapsed after accidentally kicking it with my foot. My HP AIO, and Canon printer went sliding toward the floor. Broke the printer but SAVED my big pc! (It landed on my "wadded up" sweater on the floor. Thank God for dirty laundry!)

I think I'll shut off all my stuff & go back to bed. Maybe the digital world will safer if I do!
[Android General] Old faithful:
I had a good laugh reading this as this is just about the kind of thing that would happen to my wife and I as well, lol...

For the screen apparently it's glued together, I remember seeing a video or a tutorial online on replacing the glass of a yoga, the person said it was a piece of cake to replace, I'll look for it and post a link when I find it...

Found ithttps://www.ifixit.com/Guide/Lenovo+Tab+2+A10-70+Front+Glass+and+Digitizer+Replacement/53758, it's actually for our device :) ...

also a YouTube video in Spanishhttps://m.youtube.com/watch?v=bGubRYLa8Wg for an ideatab...

Good luck!
[Android General] nannycrick:
I watched that video. I also found a website listing the replacement display for sale....

https://www.parts4repair.com/lenovo-tab-2-a10-70/

Only one thing stopping me from doing it myself...

I'm too chicken to take it apart! I'll have to find some courage.....I think that's broken too!
[Android General] Old faithful:
I started taking things apart when I was 3 or 4 ;) ... Seriously, you could start with an old camera and an old phone, that would give you the feel for the delicateness of the connectors and for the stickiness of the glue that is used... Rule of the game: if it takes a significant effort to remove you're probably doing it wrong ;)

But I'm not saying go ahead... I did these on my own stuff because I had to, living in the boonies and I was dealing with used stuff not covered by warranty... Necessity is a great teacher!
[Android General] nannycrick:
I can rebuild it...IF it's just "plug & screw" parts but not soldering! I don't have a steady enough hand for it!

I've rebuild computers and a few cells in order to save a few bucks, but not the glued in displays. I'm afraid I'll damage it permanently! I had to use #000 sandpaper to lightly sand down any "sharpness" on that corner. I hope that will keep anything, like clothing, from becoming caught on the raw edge. I also applied double side craft tape to that corner to help protect the damage spot. I hope it stays running!
[Android General] Old faithful:
Hmmm... As far as I know there isn't any soldering involved except perhaps the battery and that would be pretty simple, not like desoldering integrated circuits.

Regarding your repair I think you did good, it shouldn't go any worse considering only the edge of the glass got broken, not the LCD itself.

As for removing the glass, looking at the tutorial, that woman used a simple hair dryer, I don't think it would be too complicated, as long as you have some basic dexterity, of course ;), just don't sell yourself too short!
[Android General] nannycrick:
Thanks for the vote of confidence but.....

I'm still chicken!

I think I'll do it in stages....order the glass...then stare at the replacement glass for a few weeks....then get irritated at my own "chicken - ness" and just do it!

Anyone work up a custom ROM that they want to share yet?
[Android General] baude:
Hi all!

I'm a new Lenovo Tab 2 A10-70 user. It came with Android 4.4, and, as for now, I'm really happy with the purchase. Maybe a little strangely laggy sometimes, but it's minimum and overall performance is better than expected.

I'm reading all the entries from this post, beggining from the end. I'm thinking on doing this:

- Download latest Lollipop firmware (S000121_151222_ROW).

- Install via SFTP.

- Factory reset.

- Install TWRP, and root.

- Disable AAL with Tzul patch.

Is this the best I can do? Any ideas? Any advices? Any wipes in any moment??

Thank you very much and bye!

PS: Of course, I've read the first GREAT post. I just want to know if there are any details I'm missing!
[Android General] Tzul:
[MENTION=5186163]baude[/MENTION] If you install Lollipop via SPFT, you can install TWRP at the same time. Just click the line of the "recovery" partition in SPFT, and then select the TWRP image to be flashed instead of the stock recovery image.

After installing TWRP, you need to run it (turn on tablet by holding power key + volume up) before booting Android, otherwise it will get overwritten by the stock recovery again.

The AAL patch is for Android 4. In Android 5, you can disable AAL in the Engineer Mode app, no patch needed.
[Android General] baude:
Thank you very much [MENTION=5919159]Tzul[/MENTION], really useful information! Could I ask what is that 'Engineer Mode app', and where I cand find it?

Also: which one of the two TWRP you have on your repository (300 or 2870) do you suggest?

Also (and abusing): my understanding is that I only need to backup these two partitions: "proinfo" and "nvram". I've read pages 40-93 of this thread, so I still don't know if there is any tutorial or guide, but for now I just don't know how to do the Readbak with the SPFT tool. If there is any guide, I would be very grateful...

Sorry for the ignorance and thanks!!
[Android General] Tzul:
[MENTION=5186163]baude[/MENTION] Engineer mode and how to get to it is explained here.

TWRP 3 is fancier and newer, so use that one. Unless you want to use encryption in Android or TWRP, then better use 2.8.7.0, because this particular version of TWRP 3 doesn't support it.

You can backup all your partitions, but proinfo and nvram are most important, because they are unique and can't be "donated" by other owners of the same tablet. Here's a very brief guide.

After you flashed the custom recovery (TWRP), you probably started the tablet.

That will OVERWRITE the recovery you just flashed back to the "stock" one.

Hi Guys,

I used method No 3 to root. I have installed Twrp & Su. But after that when i reboot to normal system, I get a message saying SU binary needs to be updated. But the update always fails. Because of this, I am not able to give any root access to any app.

Any ideas what i can do?

Thanks
[Android General] Sparkrite:
Ok, try this.......

Attempt to un-root it, I'm out and about at the moment so I can't check it but I think SU has an option to do this.

Then boot into recovery and when exiting TWRP if no root is available then TWRP should prompt to root it.

Allow this and all should be okay then.

Hi again!

Updated to Lollipop, TWRP and Root, disabled dynamic lighting. All fast and fine, thanks for the help!

System runs perfect. The only drawback is the sound: previously (in Kitkat), this tablet had the best volume/sound I've heard from a tablet! Now (in Lollipop), the volume is MUCH lower, and the sound worse.

Anyone has experienced the same? Any solution?

Hi

I have TAB2 A10-70 L. I buy tablet with android 5.0.1 A10-70L_S00005_150917_P4.

This is a brand version PLAY (Poland).

I install a TWRP and root.

If there is a newer version of the software ?
[Android General] Old faithful:
Yes, check out [MENTION=5919159]Tzul[/MENTION] 's excellent post here

Hi

Tzul - i see on your site : Typ 1 : S000115_151228 -

how use this for upgrade TAB2 A10-70 L 5.0.1 A10-70L_S00005_150917_P4 with root and TWRP ?

Do you have a SPFT version ?
[Android General] loner.:
[MENTION=5469284]lion567[/MENTION]

Will you be porting the TWRP 3.0.2 for us?
[Android General] Tzul:
[MENTION=2785789]pinonim[/MENTION] Sorry, no, since I don't have a Tab 2 A10-70L.

You could try to install S000115_151228 with a stock recovery, and then install the two incremental updates (S000115_160119 to S000116_160129, followed by S000116_160129 to S000117_160226).
[Android General] pinonim:
How install S000115_151228 ? it's not a SPFT version .
[Android General] Tzul:
[MENTION=2785789]pinonim[/MENTION] That's why I said use the stock recovery. Download the type 1 firmware zip file and copy it to the tablet. Then boot the recovery: turn off the tablet completely, then press and hold the volume up and power button keys until the boot menu appears. There, use volume down to select "recovery" and volume up to confirm.

In the stock recovery, use the volume buttons to navigate the menus and power button to confirm. Select the firmware zip file for installation.

If it fails, then just mix and match your own SPFT firmware:

A: Download the S000115_151228 type 1 firmware.

B: Download my bootloader and stock recovery collection.

For the SPFT, you need the following partitions:

preloader -> from B: Bootloader\Lollipop\preloader_hq8752_tb_b2b_l (20150907).bin

lk -> from B: Bootloader\Lollipop\lk.bin

boot -> from A: boot.img

recovery -> from B: Stock Recovery\A10-70L_S000115_160119_ROW\recovery.img

secro -> keep your existing one, or try the one from the S000018_150423 SPFT package

logo -> keep your existing one, or try the one from the S000018_150423 SPFT package

tee1 -> from A: mobicore.bin (the scatter file calls this "trustzone.bin", so you can rename the file to that)

tee2 -> exact same as tee1

system -> from A: take system.new.dat and system.transfer.list and use sdat2img.py to convert these to a system.img file usable with SPFT.

cache -> doesn't need to be flashed, just wipe it in the recovery ("factory reset") after everything else was flashed, before you boot Android

userdata -> doesn't need to be flashed, just wipe it in the recovery ("factory reset") after everything else was flashed, before you boot Android

Sorry if that sounds complicated, but that's the way it is.

Oh, and you should of course make a complete backup (readback) of your existing partitions before you try this!
[Android General] lion567:
Not sure, something wrong with TWRP 3.0.0-0? I've looked through commits in GitHub TWRP repo form 3.0.0-0 to 3.0.2-0 and don't find any significant changes. Most commits are about some language translation improvement.
[Android General] loner.:
Nothing wrong with 3.0.0-0 that I know of.

What’s new in 3.0.2-0:

Fix a bug with the input box that affected masked inputs (passwords). This fixes decrypt of full device encryption on devices that support decrypt. This bug also impacts encrypted backups. Users are highly encouraged to stop using 3.0.1 if you use encrypted backups or if you need decrypt of data in TWRP.Add Greek translation to some builds.

We need your help! The bulk of TWRP work is done by 3 people on a volunteer basis

Hi guys. Sorry about staying "outta the loop" here but I had to deal with home PC issues. My HP randomly shuts down. Error log says voltage fall off, possibly due the desk collapse. (It fell over before trying to slide to the floor). I manages to buys a 6mo old Toshiba Satellite C55-B laptop. It's Win10Pro x64 w/ 6GB RAM & 750GB HDD. Guess what I discovered... W10 does NOT natively have the ability to transfer files from one PC to another. You have to install a third party program like PC Movers. I have limited network, so I'm migrating (by thumb drive) over 7 years worth of files! Grrr! When it rains at my house, it pours....BTW...

Today is the first sunny day in 16 days of rain...and it's Friday the 13th too!

Maybe I shouldn't be playing with computers today!

And no...I still haven't replaced my cracked screen. Got the replacement glass...but still chicken!

I am really surprised no one has put together a custom ROM for this device.
[Android General] Tzul:
[MENTION=5142831]loner.[/MENTION]

First, Xposed has significantly diminished the need for custom firmwares. What are you looking for in a custom firmware that can't be done with an Xposed module?

Second, there are a few custom firmwares for this tablet. I thought you had tried BlissPop by psihop a while ago. But yeah, they are buggy.
[Android General] loner.:
Marshmallow wouldn't hurt or even lollipop 5.1.

Purchased Tab 2 on Amazon few weeks ago. Finally had a chance yesterday to unbox. Booted it first time and setup with my Google account. Then let it update. Enabled developer mode and enabled USB debugging. Tried the Kingroot app in Play store. However it didn't work. Went to website and downloaded newest version (4.95 I believe). This version worked great. Then followed directions to remove Kinguser and replace with SuperSU using a terminal app. . It error-ed out the first time so tried again. Worked the second time. Updated binaries then rebooted. Next downloaded a free MTK engineering mode app from play store and using that app navigated to the AAL setting and turned it to "off". Then rebooted once again for good measure. Tablet works great and flawless. I did have to replace the lenovo charger that came in the box. It would not charge the tablet past 75%. Found a spare 5v/2a and charged up to 100% in 20 minutes. Also ordered the lightweight off- brand case from Amazon with magnet in lid and it also works great shutting off display when closed. Very pleased and tablet is wonderful!!! Thanks to all the users before me with this tablet that put together the great root instructions and various tips and resources for making this tablet even better. Love the screen resolution. For $179, can't beat this tablet.
[Android General] lion567:
Xposed won't patch stock ROM with newest Google security updates. Stock ROM still has vulnarable Stagefright Multimedia Framework.

And Xposed won't allow neither USSD requests nor voice calls on this tab.

Many security enhanced apps, such as mobile internet banking, or corporate remote access, hate Xposed and root on stock, but works with CM even with embedded root (cm-su).
[Android General] Tzul:
[MENTION=5469284]lion567[/MENTION] The fact that there are no global, regular security updates is a problem of Android in general, the availability of a few more custom firmwares wouldn't fix that. Xposed probably could allow USSD requests and voice calls (only on the A10-70L, of course), if someone made a module for it.

Security-critical apps definitely should complain about root and Xposed, because they can compromise the entire system. If these apps don't complain about cm-su, then that doesn't make cm-su superior, but means the apps are dumb and must be updated to detect it, too.
[Android General] lion567:
AFAIK Xposed couldn't allow voice calls, it's blocked at lower lower in modem and NVRAM settings.

As for cm-su - it's integrated in CM code and much more secure intelligent, than external root tools for stock, thus introduced less security risks.
[Android General] Zerreth:
Got it today. Very good device for only 175 € ! I'm impressed. Seems as good a deal like the Nexus 7 was in 2014. Only negative I can see atm is being stuck on Lollipop. So CM for this device would be awesome.
[Android General] donharter:
I just got a new Lenovo Tab 2 A10-70 Root. I thought it was $100 off at $180, but it seems that others have bought it for much less. So much for a corporate discount. I was able to root it with kingroot. I then tried to replace it with supersu sing the wolfdroid method. That failed. I went to look at the apps and kingroot had its uninstall button grayed out. That can be fixed by going to the security settings and changing a few settings. I was able to uninstall kingroot then. I no longer had root access, and could not run the wolfdroid method. So I reinstalled kingroot. When I first installed kingroot there were some extra options that I chose. I probably made it more difficult to remove it. I found an app on the playstore rashr that with root access you can flash files. So I flashed custom recovery for twrp. I was going to try the other method to install supersu and get rid of kingroot. That did not work. supersu seems to be installed. But when I run the root checker app it shows that /system/bin/suSU is really owned by a package kingroot. If I had the correct file I might be be able to overwrite that in a terminal window but probably not. I was afraid of bricking my tablet so I reinstalled kingroot. It is going to be there anyway if I "install" supersu. Perhaps I need to flash supersu somehow or maybe kingroot won't let me do that.

I found that the flashtool mentioned did not work under windows 7 or linux ubuntu. I had the generic SAMSUNG USB drivers installed in windows. I upgraded to windows 10. Maybe I will try that. I know why they give it away now. It gathers data and sends it back to microsoft who can resell that data to others. It is kind of like spyware.

backup my personal ROM

Hi Tzul, Hello to all

First sorry for my googled-English.

I have a tab2 10-70L and I would like to make root and upgrade to the latest version.

But before doing so I would like to do a full backup of the various partitions of the tablet so that I can return to the original version by SPTF in case something goes wrong.

I did it for another MediaTek phone based but in that case I used MTKdroid: in practice mtkdroid has made me a original ROM based on my phone. Here I do not think that you are using this tool. Probably I could not find it: when it reports to me, please.

Or perhaps is the backup done using SPTF? (which scatter.txt file i will use?)

Help me, please, because this is the first step to continue with this tablet.

The current version is A10-70L_S000018_150423_ROW

The version that offers me the upgrade is: A10-70L_S000019_150625_ROW

Thank you all for your attention and rest eagerly waiting for your tips :)

Luigi

[MENTION=5016849]luighigno[/MENTION]

A10-70L_S000019_150625_ROW is just a small update for Android 4.4. It's the last one before you'll get Android 5.

Therefore, you don't really have to make a backup before you install A10-70L_S000019_150625_ROW, but rather after, i.e. before you install Android 5.

Yes, you can make a backup with the SPFT, see here. It does not automatically save the userdata partition (your apps and data), so if you want to make a backup of that, too, you'll have to manually add a new region, start address 0x8f800000 and length 0x313580000 (for 16 GB tablets) or length "0x6b7380000" (for 32 GB tablets).

Or you could flash TWRP and make a backup with that. Since you're still on Android 4.4, here is TWRP 2.8.7.0. This download also contains a scatter file (well, two, for Android 4 and Android 5, but they are identical where it counts).
[Android General] Nameless crowd face:
Is there any other way to get twrp image on besides the sp flash tool? When I try to load the scatter file, the sp tool says "initiating scatter file failed. Please check to make sure the file you loaded is legal". Any help is apprectiated.

scratch that. Just went the kingroot route, then switched to supersu, downloaded, extracted and transfered the twrp.img file for lollipop and flashed it with flasher. Badda bing badda bam badda boom.

On another note, kingroot worked fine on lollipop for me (in case that wasn't obvious)

SPFlashtool and noobs

SPFlashtool is a 100% invaluable tool for any Mediatek based device and I can not recommend it strongly enough :good:

It really is worth spending just a little time and effort to get to know it and how to use it. :silly:

Nothing backup's your device better and nothing restores your device better than SPFlashtool. :good:

There are thousands of how to tut's and videos online for it's usage so no excuses for not using it really.

The likes of [MENTION=5919159]Tzul[/MENTION] etc etc recommend it's usage for good reason and not just to make your life's a little harder

There's no beating SP Flash to get true ownership of this tablet!

Oh, and just looking into it further and similar links launched an onslaught of malware attacks that required me to Ctrl-Alt-Delete Firefox and restart it in Safe Mode to clean out the numerous tabs and windows it tried to launch, one link even tried to launch a JAVA update, a SERIOUS security issue.

please remove that link
