I would be very interested to try the Blissrom on my A10-70F but I am confused by all the posts and changes that needs to be made.

Can someone post a link to a flashable ROM or TWRP backup that has the English version, with the correct Boot Loader and Kernal etc. for my tablet?

I am sure other noobs would also appreciate this.

Thank you
[Android General] Sparkrite:
I haven't tried it myself but [MENTION=5353647]zMILWAUKEE[/MENTION] links to a post where he has kindly uploaded, for TWRP, what he terms " a wrinkle free backup", see:-

Well loner, this morning I bricked my tablet on purpose just to replicate the same errors you were getting in SPFT, I to kept getting that same brom error. The first thing I did was connect my tablet to the same USB port that I had my tablet originally hooked to when I installed the VCOMM drivers. Second I held down the power button for about an additional 20 seconds after the screen went black. And what do you know, first session of SPFT after that went flawlessly. I'm not sure, but I think having the tablet hooked to the same USB port that I installed the VCOMM drivers on made all the difference. Now I'm back at it again. But I might just stay stock KitKat for a bit.
[Android General] clsA:
Not recommended on lollipop it stopped my tablet from charging. I had the SPFT back to stock to fix it.
[Android General] charlestek:
Doesn't he have to set the option .ini file so it shows the correct blocks?

Oh, no that's only for readback, my bad

[ReadBack]

ShowByScatter=true

Ah, [MENTION=567635]Loner[/MENTION] got it to work. I wrote too soon. It is nice to know that it is hard to brick this device.

Lenovo does have the full service manual on the support site for the A10 70 showing you how to dissassemble it.

However, you have to know how to use plastic pics and the operation looks so delicate that one could break the tablet easily.
[Android General] zMILWAUKEE:
I've been meaning to ask, did you do a dirty flash. If so that could be where your problem came from. I know that you have been here a while, not just to you, but anyone that's going to flash pretty much anything through TWRP. Make sure you guys wipe everything, I.e. boot to TWRP, click wipe, advanced wipe, and check all boxes except exsdcard. Then do your flash, or restore. I know most of us here already know that, but maybe a flash "noob" ;) finds this useful.
[Android General] clsA:
Yeah I wiped before restoring it. The tablet showed it was charging but continued to drop all the way to 29% before I flashed it back to stock lollipop. The DPI settings and the wallpapers looked horrible. And it didn't take long for me to remember why I dislike CM Roms.
[Android General] zMILWAUKEE:
Yeah I just ditched the blisspop myself, I started getting overheating, lag was getting unbearable, and the battery didn't last long at all. I think when people decide to "custom ROM" they forget how great the original product is. This is an awesome tablet, like we all said in the start of this thread, compared to most tablets, this one is relatively bloat free, once you get past that ugly and stupid launcher 3 this is by far the best tablet out there under $250.00. All we really need is a modded stock based ROM, and frankly I'm not sure how much modding we really need.
[Android General] Sparkrite:
Well said, couldn't agree more.

Don't think I'll bother flashing it now. ;)
[Android General] loner.:
I don't agree totally. I have had good luck with custom Roms as a rule. Most that are on XDA anyway.

That blisspop ROM was not what I would call a supported ROM.
[Android General] clsA:
You can try my backup here https://androidfilehost.com/?fid=24369303960686497
[Android General] loner.:
Remember "XDA-Devlopers" is what they call these forums and we will not get our own leveno tab2 a 10 forum until we get development started, IMO.
[Android General] zMILWAUKEE:
I'm a flash junkie, tried it out first day I ran into this thread. I think I'm going to stay stock, cause I have my eyes on a new tablet and this one will go to the wife. Yoga tab 3 pro.
[Android General] loner.:
You could always get the Yoga tab 3 for the wife. ?
[Android General] Old faithful:
Indeed all that's really needed is to freeze/uninstall stock apps you don't use and it works great. I truly believe it lives up to its slogan "For those who do".

As a matter of fact, it needs less than half the apps my Galaxy Note 2 needs and lasts more than thrice as long between charges, with no perceptible lag at all.

I'm actually looking at getting a second one for my wife... As soon as we can find a keyboard that will work with it. We've already tried some apps to replace what's running on her laptop and it seems to work fine, methinks she's probably going to retire her laptop, won't be one moment too soon with that horrible bug- (er, I mean 'feature'-) and adware-infested Vista.
[Android General] zMILWAUKEE:
She's spoiled enough, it's my turn. :o
[Android General] Old faithful:
No, the idea is once you've got a device optimized and one you like you should stick with it ;) Heck my wife wouldn't call me the old faithful if I wasn't still able to get my mojo working after 20 years :D
[Android General] zMILWAUKEE:
I really wish that lenovo would have, or as a matter of fact, advertise more than they do. If more people were privy to how great their products are without the inflated price tag, lenovo could really make a run at the giants like Samsung, and LG. My wife has the galaxy tab s, that according to the specs, just specs, is a better tablet than ours. Well I messed with it for about two hours and noticed lag issues with just clash of clans and boom beach, and the constant drop signal with wifi really gets annoying. So even though the hardware is better, the Tab 2 out performs better in real world use. And at the price I always recommend our Tab 2 over anything else.

Hello guys,

After root and installing super-sume , it removed king root and installed the su after install the su updated and got successs the asked to reboot , after that tablet hang on first white lenovo powered by android and doesnt come up, I formated cach and dalvik several times but didnt fix.

What do you think , any help ,????
[Android General] zMILWAUKEE:
Try a factory data reset from recovery. If that don't work, get yourself familiar with SPFT (first page in thread) and remember to never use King root again. For one it doesn't give true root privileges to you, most root apps work but there is still a ton of apps and functions you still won't be able to use. Kingo root is a lot better, and on KitKat the apk works good to root, and all you have to do is remove kingo su and install chains SuperSU with full root.
[Android General] alireza40ir:
It doesn't work,

where can I find latest version Of A10-70l flashable zip or firmware. ????
[Android General] Papanik:
Guys, the weirdest thing has happened with this BlissPop ROM. Without me doing anything for this, the internal storage of the tablet is full and "there is not enough space and some functions may not work properly"!!

I even deleted some apps the other day, seeing that the space had decreased for no reason, and still, it got full.

Anyways, back to my beloved stock Lollipop. Thank god I kept a backup.
[Android General] zMILWAUKEE:
It's the two malware and one trojan virus I found.
[Android General] lion567:
A10-70L_S117_160226_ROW for SP FT.

I've found that service bmi160d write a lot to /data/misc/sensor/sensord.log. It seem that this service is for bmi160 3D-accelerometer and gyroscope and there is no such device in A10-70. So I've simply stop this service

root@A10-70L:/ # stop bmi160d
root@A10-70L:/ # getprop | grep bmi160d
[init.svc.bmi160d]: [stopped]

and delete /data/misc/sensor/sensord.log thus get rid from this problem. I'm going to completelly remove this service from init.rc in boot.img ramdisk.

Where did you find them? :confused: I've perfomed full scan with KIS (full version) several times and don't find any.
[Android General] Tzul:
[MENTION=5469284]lion567[/MENTION] The Tab 2 A10-70 does not have a gyroscope, but of course it has an accelerometer. Without accelerometer, automatic screen rotation and many games would not work. ;)
[Android General] lion567:
May be, but IMHO A10-70 doesn't has bmi160 installed https://www.bosch-sensortec.com/bst/products/all_products/bmi160, and it seems that service /system/bin/bm160d is for this device only and there is no such service in stock ROM. Whatever it is, automatic screen rotation works fine on my A10-70L after I've stoped bmi160d service.

BTW I don't find any accelerometer drivers in stock ProjectConfig.mk (/system/data/misc/ProjectConfig.mk).
[Android General] :
Do this work on the F version too? Scared to brick it..
[Android General] lion567:
*.apk coudn't be a "true" virus (like stealth viruses for Windows) because every apk required java runtime (dalvik or ART) which is separated from apk. Thus every apk is running within its own virtual environment (sandbox). And powerfull antivirus software mostly detect suspicious code inside apk.

I don't find neither ckcheckservises.apk nor provisioner.apk in /system on my A10-70L with BlissPop. I've found only /system/app/ckservice/ckservice.apk (com.android.statassistant), looked through its manifest with APKTool and don't find anything suspicious, but it not worse to disable it.

What was the Trojan name you've found and were ckcheckservises.apk was (full path)?
[Android General] zMILWAUKEE:
I would have to reflash that ROM, and don't want to. I did have a earlier post somewhere in pages 65-last so I'll find it later.
[Android General] Tzul:
Not maybe, definitely. Any simple system info app will confirm the presence of a working accelerometer / g-sensor.

According to the information in /sys/bus/platform/drivers/gsensor, it's a KXTJ2-1009.

And ProjectConfig.mk actually contains "CUSTOM_KERNEL_ACCELEROMETER = KXTJ2_1009-new bma222E-new" on my tablet.
[Android General] mmlbbntr:
Hi all,

Tried to install a custom recovery and I think I've bricked it (soft or hard)?

Just followed the instructions on post 1, tried the recovery_twrp300_for_LenovoTab2A10-70 package. Tablet had just been upgraded to lollipop.

I followed the instructions meticulously.

- driver installation, all good

- started "downloading" as I plugged it in

after a couple of minutes, got an error message, "HINT" and empty, and bricked my tablet. Won't boot, can't seem to attempt to flash another recovery file ! Any genius ideas on how to salvage this or is it good to be used as a door stopper?

If I plug the tablet on the charger, the charging icon won't even show up, that can't be good.
[Android General] zMILWAUKEE:
Does the PC detect your tablet when you plug it in, if so your good. Just flash the 5.0 firmware from page 1, then after that's done reflash TWRP. After flash of TWRP make sure you boot into recovery mode before you do anything else.
[Android General] mmlbbntr:
Cheers for that. Initially it didn't, hence the panic. Luckily (miraculously I should say) I just found a way around : took the back off, unplugged the battery, gave it a few minutes, and THEN the PC detected again. Phew.

Why is it crucial to boot into recovery mode before doing a "normal" boot?

That was my scare for the weekend! :eek:
[Android General] bigrammy:
Sounds like a dodgy USB lead or port to me. :confused:

Try another quality lead and or port. :fingers-crossed:

recovery.from.boot.p will just replace your TWRP with the stock recovery if it does not get disabled first.
[Android General] mmlbbntr:
Now my next problem is not being able to root. The SuperSU.zip doesn't want to flash under TWRP, strange. Although, minor annoyance compared to the earlier scare of bricking the device...
[Android General] bigrammy:
Did you swipe to allow TWRP to modify your system ?

If you didn't it will not flash the SuperSU.zip.

If you're still in recovery Go to TWRP main menu /reboot/select recovery. On restart you will get a prompt saying "Swipe to Allow TWRP to modify your system". Swipe to Allow Then flash the SU.zip
[Android General] mmlbbntr:
Initially, no. I thought the tab was bricked. Then I managed to reboot it, and, in a second boot, realised that TWRP was indeed installed. So I can access it using the normal power / volume button. Not sure which version it is though, the 300 or the 2870 since I then tried to flash the latter in hope of unbricking.

I tried booting in TWRP again and "swiping", doesn't seem to be doing much :)
[Android General] Tzul:
[MENTION=3097216]mmlbbntr[/MENTION] Here's the TWRP 2.8.7 version of the screen bigrammy was mentioning.

TWRP 3 typically looks like this. TWRP 2.8.7 has another design by default. But both versions can be themed and made to look radically different.

If you've flashed a TWRP that I've made or modified, there should be an "Install SuperSU" button in the "Advanced" menu. And TWRP should offer automatically to install SuperSU when you leave it via the "Reboot" menu and haven't rooted your device yet.
[Android General] :
I got my Lollipop device rooted with Kingroot (Even on latest version of Lollipop) and changed to SuperSU with the paid app. Trying to install recovery for Xposed, but not working well..

I have installed the drivers and they told it was successful. I can see my tablet in device manager when it's turned on and when I turn it off and insert the USB, it "bootloops" by starting to the Lenovo screen->Battery->off->Lenovo->Battery->off and so on, while keep disconnecting and connecting (the sound from the PC when it connect and disconnect with USB).

When I click download in Flashtool, then afterwards insert the USB it's saying that the device booted up too early or something like that.

Anyone that can help?

Thanks in advance

EDIT: Got TWRP to work. Just booted to bootloader and flashed recovery through "fastboot flash recovery xxx.img" . After there, it was no problem to download Xposed and flash it through TWRP.

This thread is golden and I finally achieved root on my tablet! Thanks!
[Android General] loner.:
It sounds like you are flashing the wrong xposed framework. Remember it's a different file to flash for lollipop than it was kit kat.
[Android General] mmlbbntr:
Oh wow, looks nothing like any of these, I just get a old dos looking screen :

"Select Boot mode :

[VOLUME_UP to select. VOLUME_DOWN is OK]

[Recovery Mode]

[Fastboot Mode]

[Normal Boot]"

And then another DOS looking screen, "Android system recovery <3e>"

I take it I have failed installing TWRP altogether :p

I guess I'll have to give it another shot...
[Android General] Sparkrite:
Very important to boot to TWRP as soon as its flashed, otherwise it gets overwritten. What you have is the stock recovery.
[Android General] mmlbbntr:
Thanks, indeed. I think my problem is that step 5 fails. I never get a green "OK". I get "Download DA 100% but the bar stays in red. Eventually just times out...
[Android General] Tzul:
[MENTION=3097216]mmlbbntr[/MENTION] Yeah, "Android system recovery <3e>" is the stock recovery. Which version of the SPFT are you using? Some older ones didn't work properly. Try the latest one (v5.1604) from here.
[Android General] kalv13:
Hello!

I followed the steps and everything works great, but since i downgraded to kitkat 4.4 i cannot acces my wireless 5 GHz and the 2.4 GHz is very slow. Any way to fix this using the file manager since my device is rooted?

thanks
[Android General] loner.:
Same thing happened here. My device doesn't even detect 5 GHz anymore.
[Android General] kalv13:
I wonder if it possible to activate via the Files manager/Device or maybe update the wifi only manually.
[Android General] loner.:
I don't know what the answer is, but hopefully someone does.

I'd like to connect at 5 GHz again, but since I downgraded to kit kat then back to lollipop my devices can't even detect the 5 GHz
[Android General] charlestek:
I had come across a page supposedly offering a tar.z download of the wireless drivers, but in fact it is just 70L source code.

The actual download URL is from Lenovo for the "L" version : https://download.lenovo.com/consumer/open_source_code/lenovo_tab_2_a10_70L_osc_201504.tar.gz

The top level folder is "alps".
[Android General] kalv13:
Any idea how we can install this lenovo_a10-70f_osc_201504.tar.gz

Got it from Lenovo, but im not sure if i need to unzip and add it to the tablet or how to install it.
[Android General] charlestek:
This is raw source code, it needs to be compiled. Firstly, I should not have posted without a disclaimer.

In android there aren't exactly modular driver compiled executables for drivers.

I don't know exactly what it is. This is not like a Windows OS where there are driver files for a device/chip.

Ok, stupid me, I had to look closely at the URL, this is Lenovo's posting of the source code probably for GPL fulfillment.
[Android General] kalv13:
It look like of some kind of update for the tablet that can be installed. But also it might also update the android version, well is just a guess.
[Android General] charlestek:
No No, it is just source code, for example, look here: http://support.lenovo.com/us/en/downloads/ds102575

The webpage may have been crafted to display some advertising or possibly worse. I will edit out that link.

There supposedly was an OTA patch to the latest Lollipop base image that I think fixed wireless issues, I assume everyone used it.

I'm still on KitKat, one of these days I'm going to use Tzul's SPFT image to upgrade to Lollipop, his image includes all the patches and uses a new bootloader for Lollipop that the OTA version doesn't have.
[Android General] loner.:
Is there a fix or a set of wifi drivers for the Lenovo Tab 2 A 10-70F....? I would like to regain wifi 5 GHz access.

EDIT: Found the fix! All good now. WiFi back to 5 GHz
[Android General] hunteditor:
Nevermind!
[Android General] zMILWAUKEE:
Do you guys do a factory data reset after flashing. Cause I'm on stock KitKat and my tablet wont connect to any other wifi band but the 5 GHz. Also are you using wps button or the passcode you set for router. Try just using wps first. Then if that don't work do a factory reset and try it again.
[Android General] loner.:
No thanks, all good.
[Android General] kalv13:
Can you share the fix with us please? =)
[Android General] loner.:
After reading all I could find in forums and blogs about the issue, which almost nothing, except for one small comment.

I turned on the Bluetooth, went back to the WiFi connection availability screen an it showed all the 2.4 GHz and 5 GHz WiFi in the area. So simple, but it worked for me.
[Android General] kalv13:
sadly it didn't work for me, but thanks anyway!
[Android General] loner.:
Are you updated to lollipop?
[Android General] kalv13:
Im still on kitkat 4.4, main reason is because i needed the multi-users. But since then my wifi is so bad. Also its weird since i installed kitkat 4.4 i cannot do a factory reset/recovery when i press it nothing happen at all, only the android logo appears.
[Android General] loner.:
You should update to lollipop. There may be a multi-users app for xposed. You can always downgrade if you need to after that.
[Android General] kalv13:
I am not really sure where i can find it, any link by chance =) ?
[Android General] Tzul:
[MENTION=7420991]kalv13[/MENTION] Here's the module. It's not without problems (missing icon in the quick settings menu).
[Android General] kalv13:
Thank you!

I will try this out. So my understand is that i just download this module on my tablet and execute the com.anton111111.xposed.multiusers_v1_82c990.apk. ?
[Android General] mmlbbntr:
Was using SP_Flash_Tool_v5.1524.00.000, will give the newer version a go.

Edit : thanks! Did the trick. The new version worked flawlessly, I'm now the happy owner of a fully lollipop upgraded and rooted tab 2 A10-70F :)
[Android General] kalv13:
I installed the module, but i do not see users to active the multi-users
[Android General] loner.:
To flash Xposed Framework, then the modules you want for Xposed, yes you have to be rooted.

The latest Kingo Root (from XDA), rooted lollipop just fine for me about a week ago. You may want to read up on it, if you have never tried it before.
[Android General] clsA:
You need more than just root

You need TWRP custom recovery to flash the xposed framwork.

Its all in the 1st post here

Kingo root is useless if you have custom recovery. Just root the phone when you exit TWRP
[Android General] loner.:
Funny thing, when I got my tablet working again I couldn't get TWRP flashed, probably due to complications from my tablets previous death (hard bricked). Kingo Root got me rooted, then after that I finally managed to get TWRP flashed. It definitely wasn't the way I did it the first time.
[Android General] loner.:
Tab 2 A10-70 on clearance for $134.00, where I got this one. They must be getting ready for this year's edition. Can't complain about the clearance price, I would pick up another one if there was a custom ROM for it.
[Android General] philje123:
I've had Android phones and tablets for years and very happy with this tablet.

The latest update is 5.0.1.

It will prompt for an OTA update. You're fine to install it then run Kingo root. Then use the instructions with the terminal commands on this thread to replace Kingo with Super SU.

Not bothered about recovery or xposed just wanted root to get rid of a couple of apps and install and blocker.
[Android General] Tzul:
[MENTION=4139144]Jessooca[/MENTION] I'd say it was a good buy (unless you paid too much for it). To minimize lag, be sure to disable AAL.

Latest stock update is Android 5.0.1, and if you don't trust KingoRoot, then don't use it! You don't have to. Just install TWRP as custom recovery, which then will install SuperSU. You can always install TWRP with the SP Flash Tool, but if your tablet comes preinstalled with Android 5.0.1, then "fastboot flash recovery" should also work.
[Android General] folsom68:
Do you have a link to the clearance?
[Android General] loner.:
It's not a online sale, just a individual department store clearance sale, they probably only had a few at the start of the sale.
[Android General] rumbla:
Sorry to bother you all again, but I'm in the process to upgrade to Lollipop.

Now I'm still using KitKat+AAL_patch+TWRP. Everything is quite fine, but I want to wipe the tablet entirely.

The idea is to just write over the latest firmware (S000121_151222_ROW) using SPFT.

But what will happen to the old TWRP? Will it be overwritten by the stock bootloader? If so, that's fine...I will just write back the right TWRP version.

I would also like to wipe my SDCard completely. What's the best way to do that?

What about "debloat" preinstalled-app (I don't think I ever used any of them, apart DolbyAtmos)
[Android General] Tzul:
[MENTION=7268959]rumbla[/MENTION] if you use the SPFT to install a new firmware, you can point it to the recovery you want. Just click the "location" column for the recovery partition and select the TWRP image instead of the stock recovery image.

Of course you need to boot into the custom recovery before you first boot Android from an untouched system partition, because otherwise the "install-recovery" mechanism will be executed, overwriting the current recovery with the stock recovery.

If you want to wipe the actual microSD card, you an use a card reader on your PC, TWRP, Android storage settings, ...

Most (but not all) of the useless preinstalled apps are in /system/appjar (not to be confused with /system/app). Therefore, start by deleting the entire /system/appjar/ directory (requires TWRP or root).
