ExFAT / NTFS Support

Hello,

I don't like missing out on the ExFAT/NTFS Support for the Lenovo A10-70F so I started to install these drivers

my install sequence:

flash stock Lollipop with SP Flash,

flash TWRP with SP,

install SuperSu with TWRP,

disable 'mount namesapce separation' in SuperSu app

install filesystem patch with TWRP (can't link yet but its filename is UPDATE-android-fs-1.0.4-install.zip )

reboot with SD inserted

Somehow my tablet still sees the SD as blank/wrong partition.

Anyone know what I'm doing wrong? Or do these drivers simply not work on my stock ROM?

If anyone knows how to solve or knows anything more about this, I'll be very happy to hear :fingers-crossed:
[Android General] Tzul:
[MENTION=7991731]SeriousSmorkin[/MENTION] Have you used this version? If not, just install it with TWRP. Some older versions of this hack don't work in Android 5 and had a bug that would fail on some SD cards.
[Android General] SeriousSmorkin:
Weow Sir [MENTION=5919159]Tzul[/MENTION]! You just solved it :victory:

I've overlooked this version and its purpose, thanks a lot.

Do you know what the -SUD extension in the filename stands for?

Cheers
[Android General] Tzul:
[MENTION=7991731]SeriousSmorkin[/MENTION] Since I named it, I know what it stands for. The drivers must be started on boot somehow, and there are several ways to do that, but not all work in every Android version, or on every system. I chose to place the startup script in /system/su.d - more info in the original thread.
[Android General] theclarkster:
I haven't had a chance to reply until now, but I think I managed to solve the problem. Rebooting into safe mode resulted in a smooth video experience (I agree, BTW, that the planet earth video is quite amazing!). So, I began uninstalling some apps that I suspect might be causing problems. I believe the culprit was Greenify. As soon as it was uninstalled, video started working perfectly. I have no noticeable stutter on any video now. Thanks for the feedback, and I hope my findings prove useful to someone else!
[Android General] ericDraven77:
[MENTION=3924647]bigrammy[/MENTION]: I don't know why, but my phenomenon is gone now. I played around with the Atmos settings and now everything works just fine.

Thanks for your help!

MM NTFS/exFAT patch

Hello everyone. Can an NTFS/exFAT patch be applied to Marshmallow 6.0 (A10-70L_S000212_161020_ROW) version? I have tried this:

androidfilehost.com/?fid=24591000424946907

version, but Android tells me that SD card is corrupted and formats it to FAT32 if I try to 'fix' it.

I got TWRP 3.0.0.0 with SuperSU 2.79 ('Mount namespace separation' unchecked), Magisk 10.2 and Xposed 87 (systemless) installed.

TWRP can see and write to exFAT SD card and resulting installation log is clear from errors. Then I clear cache and reboot with no luck with my trouble.

Got my Lenovo Tab 2 today finally! Ordered it because of this thread & zMilwalkee, BigRammy, & TZul's work & efforts! The SP Flash Tool is so easy to use I can see it being "childproof" to some! Did not have to load the SP driver from OP, just plugged it in and Win 10 loaded it. I have Marshmellow installed, did a factory reset. About to put TWRP on, then flash the custom modded boot.img & chSuperSU's latest Systemless! I am looking at Systemless Xposed " https://xdaforums.com/xposed/unofficial-universal-systemless-t3419472 " but all the api's are named the same?!! Anyone know which one?

You can now also activate Google Assistant on non-pixel devices running MarshMellow (Google Everywhere) with an Xposed module!

Anyone have an idea as to which Systemless Xposed (a link would be nice), I definitely would appreciates it!

zach

ps there is also a Viper4Android that has Dolby Atmos built in as well, checking to see if there is a flashable compatible version for MM!

1 last item: What's up with the Wi-Fi? 2.4ghz says I'm connected at 135mbps but its taking like 5 minutes to download 7.93mb app from playstore?? Same on 5ghz....... ??!!!!

---------- Post added at 05:49 PM ---------- Previous post was at 05:00 PM ----------

Just posting I guess, quite in here!

TWRP, tried wiping, formatting but it said could not mount data, yadda yadda yadda down the list,

went ahead and did modified boot.img & SuperSU, its got the progress bar at bottom, booting up now.

Guess all thats left is the "fixes", figuring out which Systemless Xposed to use!!!!

$$PROFIT$$
[Android General] bigrammy:
SPFlashTool: :good:

Boot.img:

In Brief:

The stock boot.img will fail as you described with any type of systemless root due to SuperSU not been able to figure out how to unpack the older style Mtk boot.img.

Using my repacked boot.img allows SuperSU and any type of systemless to unpack/repack the boot.img without error.

Using my repacked boot.img without flashing SuperSU will cause issues due to me removing forceencrypt only.

This was only done to ensure It does not re-encrypt peoples userdata by accident.

So it needs flashing in conjunction with SuperSU which does all the wizard stuff for it work correctly. :cool:

Wifi:

Seems OK for me :confused:

Superfast

Don't know what was up with the wi-fi but like alot of others have posted problems fixing themselves after flashing your modified boot.img.... Same here, downloads are in milliseconds! The screen going to the progress bar is just a formality now because it just flashes a brief blink of the eye then goes to installing :good:!

Thanks everyone for all the time, effort, & brains making this a superb up-to-date tablet!!!!!

I need backup nvram (twrp 3 or other method). who can give it to me? F tablet version. thanks in advance
[Android General] zMILWAUKEE:
Dang buddy, no hi hey how is everyone doing, just I NEED off the top. Listen this is not a file swap site. This site is meant to educate, share ideas and in the grand scheme of things, MAKE ANDROID BETTER, hence Android being based off the GNU project and being "open source". So to answer your demand, what problems are you having and maybe these smart folks here can guide you to a fix. I pretty much know what issue your having but to just send a file and not teaching you how to fix it defeats the purpose of XDA...
[Android General] Piligrim1995:
my tablet nvram error. after a reset to factory settings, set the wrong MAC address... I'm looking for people who can help me to recover the tablet to its original state. because of this, I ask the backup. :( my goal is correct nvram and write my values
[Android General] zMILWAUKEE:
first before we can help. What Android version are you on. And if you want stock, then refer to the first page of this thread...

---------- Post added at 04:57 AM ---------- Previous post was at 04:42 AM ----------

Look, I dont know about everyone else, but im sick of these "noobs" getting in XDA for no reason at all, and i myself am sick of giving knowledge to those that will never contribute to the true Linux experiance. Making it better and sharing what all of us learn on this site. No more spoon feeding and letting those that just want to be "cool" make the mistakes needed to learn and contribute to the "open source" project thats dates back further than most of us have been alive....sorry for the gruff attitude but im sick of pointing this and that way, when people are not willing to get that answer they are looking for, or willing to make the ANDROID experiance better. XDA was not meant for that. Lets make this "XDA" better than anyone could imagine.......
[Android General] chris5s:
Have you tried here?

Or reflashing stock ROM in SP flash tool might help. It's worked for others with MTK devices in similar situations...
[Android General] Piligrim1995:
i tried flash rom in SP flash tool. is does not fix. after reset wifi mac - 0x12 :confused:

i know about the patch, but this is a temporary solution again to reset. i see stranger mac, after flash the patch.

i began to receive an nvram error after the return android6 to android5. on android4 does not have this error :eek:

but nvram a separate section. during a flash SP ft save section and writes it again.

lenovo tab 2 a10-70F android 5.0.1 stock.

I understand it. I despair. in Russian forum 4pda exact same situation with newcomers

It should be great is someone could do a video tutorial...:o

Thanks!

Hello, Tzul and other experts over here. Have you got any ideas on how to make NTFS patch work in MM version? I posted some info about it. I would appreciate any help from you. Thanks in advance.
[Android General] Piligrim1995:
my problem happy end

I describe step by step what I did to restore the nvram on A10-70F:

1. download stock rom A10-70F_S122_160505_ROW. this firmware has apdb

2. download SN_Write_tool_exe_v2.1504.00 for generate new nvram

3. flash stock rom s122 (Frimware Upgrade) (have installed driver MediaTek PreLoader USB VCOM)

4. turn off tablet and start SN Writer.exe

5. settings in programm:

com port: usb vcom

target type: wifi tablet only

press button System config

checkbox BT Wifi address

specify the file AP_DB in folder unpack stock rom A10-70F_S122_160505_ROW\Target_bin\APDB_MT6752_S01_L0.MP6_W15.20

save and press Start

6. usb connect the tablet off

repeat the six point, if nothing had happened. because the tablet has to enter in a meta mode

7. Flash newest rom and Factory reset.

now you have the correct nvram. even after a factory reset will not WiFi NVRAM WARNING: ERR 0x10

do not need flash WIFI, WIFI_CUSTOM

Sorry for Google translator :silly:
[Android General] Tzul:
I get where you're coming from, but that wasn't particularly helpful. [MENTION=5814862]Piligrim1995[/MENTION] has ruined his NVRAM partition. Nothing helps there except flashing a good copy. Which isn't included in firmware releases, because the NVRAM is unique for each tablet, as it contains MAC addresses (and IMEI on devices with SIM card). You can work around the problem by copying extracted NVRAM files to /data/nvram, but that's an imperfect solution, for the files will be wiped by the next factory reset.

Piligrim1995 could flash someone else's NVRAM partition, but that would mean sharing IDs that are supposed to be globally unique. Unfortunately, it's not possible to simply patch in new IDs with a hex editor, because the data is protected with checksums. I have been working on reverse-engineering them, though.

Edit: yeah, that SN Write tool is another solution. It will rewrite the NVRAM partition, but it requires those database files which might or might not be available.

Sorry, I'm not using the beta Android 6 on this tablet and therefore haven't tested the exFAT/NTFS drivers under that condition.
[Android General] chris5s:
At least he got it sorted...:good:
[Android General] errorist404:
Thanks for the answer. Any plans in trying Beta version for yourself? Or in my case with exFAT it's better to downgrade to 118 if you're not interested in MM version.
[Android General] coolbeans2016:
okay, same here

Just flashed Xposed on this A10-70F running MM 6.0, and wifi pops up with open wifi notification. Under wifi it shows :

NVRAM WARNING: Err = 0x002 2.4ghz

Authentication Problem

WTF?!!!

Is this a problem that will cause hardware errors?

Completely NEW 2 me!!!!!!!!!

zach
[Android General] chris5s:
Had you flashed any modules? I don't use xposed myself.

At least you know how to fix it :good:

Peace.
[Android General] coolbeans2016:
read into it more

After reading into it more, this error with 0 x 10 means a lenovo phone has been flashed with incorrect IMEI, what has happened is this F version of MM designed for LTE SIM service has left this device without an IMEI, so far no problems connecting with wifi, so, hey, I can live with it! Just freaky!
[Android General] chris5s:
At the end of the day, we're flashing software not exactly meant for the tablet (those with the 'F' version, at least), so these issues aren't entirely unexpected?

Glad it's not fubar :D
[Android General] iosifp86:
Hi I am new and noob and I need some help. I just bought the tablet for my wife (wifi version) and I try to Install Custom Recovery (after it installed the latest update, I think 5.0.1) When I reach to the step where I must "Connect the turned-off tablet to the PC. Recovery will flash in a matter of seconds and you will get a big green OK on the software." the SPflashtool red bar loads to 100% (Download DA 100%) and then nothing happens no yellow bar no OK message. After 44 minutes I got this message "BROM ERROR : S_FT_DA_NO_RESPONSE (4001) DA didn't responce data to Flash Tool! [HINT]:"

Tried with the recovery twrp 300 but still the same. Any ideas???
[Android General] bigrammy:
Quoted from https://forum.hovatek.com/thread-439.html

My bet is

1. Drivers

2. USB port If you have a USB2.0 port then use that if the driver is correctly installed.
[Android General] coolbeans2016:
NVRAM

I ran into the same issue, either way I have a fix for you, just researching it a little more. I'm trying to not just fix this NVRAM WARNING: Error 0x2 2.4GHz message in MM 6.0... trying to fix it and retain both bands 2.4 & 5.

Sorry for being so late responding. If this no longer applies to you, please write back either private message or in here just to let me know.

Thanks,

zach

ps I can confirm that the MM 6.0 FW after installation does have both bands working without error, believe its Xposed, or after flashing modules this occurs, will make note of everything as I load back up.
[Android General] elessar18:
Hi. I tried flash rom with this guide, but now my tablet dont even want to start! The weird thing is sp flash tool showed immediatly flashing 100%, and then nothing. Normal turning on dont work, volume up+ power button for 10sec dont work, even volume down+ power button dont want work!

What can i do to force tablet to ANY respond?

PS: When i connect tablet to pc via USB i hear sound of connected device, but without information what was connected. So its only sound, i cant tell that pc recognised it as lenovo tablet.

PS 2: Anyone know hot to disassembly this tablet? I want to try remove battery
[Android General] bigrammy:
It's your DRIVER!! as discussed a thousand times in this thread. :crying:

Open Device Manager then plugin the tablet and watch what happens.

You will see something like serial & comports show up briefly so try to catch it before the tablet disconnects it's self.

At the side of serial & comports click the > to expand it you will now probably see an ! in a yellow triangle.

Now install the correct driver manually Here
[Android General] demeez:
Is there a way to get the volume to be as loud as it was under Kit Kat with LP/MM? I've tried adjusting the db in Dolby Atmos and it gives a little bit of a boost but it's still pretty low when listening through the speakers. My primary use for the tablet is streaming videos when I'm eating at the table so I always end up reverting back to KK just because I can't get it to sound as loud anymore. Would installing Viper improve this? When I try to uninstall Dolby first however using Titanium Backup I get a warning that it couldn't find the apk. Any help is appreciated, thanks.
[Android General] kidanime3d:
Thought I would touchbase and provide a workaround to the headphone issue on MM, the app soundabout forces the sound via whichever playback method you chose, via hardware triggers in the code.

Also managed to get near perfect standby time, <2% drain after 8 hours deep sleep by de-googling the device; removing play services( not needed for netflix, nowtv etc), and implementing the other mentioned fixes. So far it is very stable. Happy to provide ful detail and steps if anyone is interested
[Android General] Old faithful:
Any info on helping to get rid of Google is welcome to me. I've disabled the PlayStore (I donwload apks directly) and don't run Gmail (I access my gmail accounts through Aquamail) but haven't been able to get some apps, such as Weather Underground, running without Play Services running, even with hacks and stand-ins through Xposed.

In other words... I'd love to know what you did and how you did it!
[Android General] Stretto:
I have used the device extensively after "romming" and it works well. I get about 14 hours of battery life when in use with standby(I removed a ton of crap).

The only problems I have consistently is this:

1. Wifi seems to lag and not be very fast. When I try to stream videos through firefox or opera either it doesn't work half the time(they stall) or it works fine and any refresh of the page will cause it to general stall. It seems to be progressive. Could be an issue with firefox but happens in opera too(I think the video doesn't even work in it as it just stalls on the first frame). It's like when you are downloading a ton of stuff and have no bandwidth then try to stream something and it tries to buffer but never really plays.

2. Headphones issue(I might have to retry that hack, Might not have forgot to do it after the second flashing. Basically device thinks the headphones are always plugged in.

3. The high volume warning is so annoying. I tried to hack the volume and force it to be max but it alway starts at around 50%, which is very quiet, and I have to raise it to 100%.. and I get that warning. I'd like for it to remember the volume and to remove the high level warning.

Any ideas about the wifi issues(It's the device or the connection, computer on same line runs at 30Mbps just fine. I can stream 30 videos simultaneous and I can't even get one to work well on my tab(well, works well about 1/10 tries) or how to remove the volume warning?
[Android General] kidanime3d:
Before you do this i would suggest the following:

- Backing up your system on an SD Card using TWRP.

- Figuring out which apps rely on play servicies eg. Google Calendar, you will lose access and find alternatives, I use FDroid but each to their own.

Requirements:

- Amaze folder explorer

- Root

- No wifi connection( apps phoning home for updates is a nuisance)

Steps:

- In app manager in Amaze, click the three dots, select properties, click disable, remove updates

- For same app, follow the same process, however select uninstall, done should pop up, restart again

I would strongly advise removing a measured approach e.g. remove core apps, restart normal boot, restart backup via Twrp, boo into system, and repeat.

Also only turn on wifi once finished
[Android General] Old faithful:
I've had issues with WiFi as well the radio doesn't seem to be as sensitive as the one on my cell phone. It's especially problematic with older routers, takes forever to connect and tends to drop out. It works much better with newer routers although the range isn't as great as with my cell phone and laptop.

No idea, but I've read in recent postings that quite a few people have had similar problems with the latest ROMs.

Try removing Dolby Atmos and install Viper audio instead, sorry about the link, don't have it, make a search for it in this thread, there's a zip file that you can flash in recovery. Also make sure your audio app equalizer doesn't interfere with the system one like Dolby Atmos tends to do.
[Android General] deviceowner:
Hi all,

I have a question regarding the last official version for A10-70F - S000123_160921. Does it solve the problems with Wi-Fi (stability and performace). Is it worth updating?

Thanks
[Android General] Tzul:
[MENTION=7933005]deviceowner[/MENTION] The S000123 runs fine for me. But then, I've never had stability or WiFi problems with older firmwares either. Someone wrote that WiFi problems are related to using WPA with the older and weaker TKIP encryption, and that they don't occur with WPA2, which uses AES-CCMP instead of TKIP. Whether that's true or not I can't say, but it's always a good idea to check your router settings.

By the way, the model name for OTA updates used to be "LenovoTAB2A10-70F_ROW_L". In S000123 it was changed to "LenovoTAB2A10-70F_ROW_M". This could mean that we will eventually get an official Marshmallow update. Or maybe it just means it was the final Lollipop update. Time will tell.
[Android General] deviceowner:
Thanks [MENTION=5919159]Tzul[/MENTION] , however I do experience problems with Wi-Fi connectivity. As I mentioned before the tablets A10-70F are used as kiosks which are permanently connected to the Wi-Fi network which does not belong to the reliable ones (quite large by number of connected client devices actually) but usually it works fine. I experience connection drops which wouldn't be so bad if every time it does drop the device would connect back. Is there any possibility for a workaround that doesn't include rooting the device? Basically I would need somehow the tablet to force connect to the same SSID when the connection drops.
[Android General] Ceejay343:
I'd like to try the Marshmallow ROM, but I'd hate to lose the excellently working dttw feature in the official rom. I looked at proximity sensor gesture thing in Gravity box but I tried on my phone and couldn't turn on the screen at all lol.

I kind of hope we will see the official Marshmallow ROM soon, this leaked ROM is like nearly there already right? You'd think they wouldn't just try it and see how it goes, it's coming right? ?

Dolby upgrade

https://xdaforums.com/android/software/soundmod-axon-7-dolby-atmos-t3412342

My final step setting up this A10-70F on the MM 6.0 ROM was the sound. Always been Viper4Android for me and for awhile now V4A has been offered as a combo .zip with Dolby's ATMOS included. Had it on my last Samsung phone and it was great. But... so far those .zips would not work, and getting V4A on with the stock Dolby, even when working, just left something to be desired.

I found that the Dolby ATMOS music mod came just not on Lenovo's devices but a few others and when it was ported (above link) it was made alot better! The BQ Aquarius .zip was the one that worked on this tablet, and with the deep_buffer hack is included in .zip! Not even interested in V4A, least not for this tablet anymore. Thought you might want to check it out.

zach
[Android General] Ceejay343:
That's very interesting, do i need to uninstall the present dolby atmos (somehow) or can i just flash that BQ Aquarius version?
