ReadBack Procedure

The Readback Procedure looks ridiculously tedious. The article I read requires the use of Mtk Droid Tools, to take the finished readback modules and make them flashable.

http://www.theandroidhow.com/2014/05/how-to-backup-rom-dump-mtk-android.html

But before that, you have to use a scatter file, which I have no idea where to get, to read with an editor to apparently determine the beginning and ending byte addresses of a module you want to dump/readback. Where do you get the scatter file? Also the whole procedure is quite lengthy, it is too bad there is no way to semi automate this.

Hi All,

Is there a handy way to force the A10-70F (on stock) to use 2.4GHz instead of 5GHz Wi-Fi.

I'm suffering Wi-Fi dropping on sleep, despite setting to "Always On" and just wanted to rule out anything to do with the 5GHz connection. I suppose I could just turn it off at the router and test, in fact I'll do that, but I don't want to leave it off as I have too many devices that work well with the 5GHz.

Cheers.

EDIT: No difference on 2.4GHz.

Edit No.2: Anybody any ideas why the Wi-Fi is dropping when tablet sleeping despite setting to "Always On" ? It will stay on if plugged in, a bug maybe ??
[Android General] bigrammy:
Hi Sparkrite,

I had a similar issue after flashing the official stock boot.img supplied by tzul but still running my own modified L rom.

Wiping Cache and Dalvik Cache seemed to cure things for me but also double check /settings/battery/intelligent power saving is set to off. :fingers-crossed:
[Android General] Sparkrite:
Hi [MENTION=3924647]bigrammy[/MENTION],

Thanks for the reply, not sure if I have that set to off but I'll check, I have been busy flashing all sorts of ROMs and at the mo it is restoring all my apps on your Rom.

Let you know how I get on.

Cheers.
[Android General] Sparkrite:
Update on above:

I have resolved it, I noticed that whatever ROM I flashed, it worked as it should, but as soon as I restored my backed-up Apps the bugger would go to beddie-byes as soon as the screen started putting up Zzzzzzzz's !

WTF ??

Obviously some App was over-riding the default settings, but which one was the guilty offender ? Anyway after hours of frustration and much hair pulling, which is not to be recommended, when you are "follicly challanged", I traced it down to "3C Toolbox Pro". Deep in its inner sanctum a setting had been changed to put the Wi-Fi to rest along with the screen.

How this had changed is beyond me, as I had not done it, I hadn't touched this App in ages.

Maybe that explains it, it got tired of being ignored and decided "How dare you forget about me" and wanted to make its presence felt, and indeed it did, in the most underhand way as far as I'm concerned !!

Anyway all's well that ends well.

Cheers.

A10-70 stuck in boot loop, need advice.

Hello,

My son was trying to update the os or something and told me he did one of the steps wrong, but regardless, the tablet is stuck in a boot loop at the moment.

I took it apart, unplugged the battery and did a system drain. I plugged the battery back in, and reassembled it, then plugged in a power cord and they system constantly reboots itself every few seconds. It shows the lenovo/android white splash screen then reboots. if I hold the vol. up button, i can see they super tiny text for reset options but it resets before it gives me the option to choose anything. It's been stuck in this loop for about 5 hours, I left it up when I went out to dinner, but it was still doing the same thing when I came back. If i unplug it from the ac outlet it just stops and stays off so the battery isn't taking a charge to let it keep going.

Is there anything I can do or anyone know what may have happened since my son had a friend telling him what to do and really doesn't have any clue what really happened?

This is the Tab 2 A10-70
[Android General] chris5s:
Run SPFlashTool, with the ROM you want to load, making sure the tablet is turned off, and follow instructions as per the original post to flash a fresh ROM

That should do it....

I am trying to install the usb boot drivers. When I open device manager and plug in the tablet via usb, it does not populate in the list, so i am unable to select it for installing the driver. It goes into the infinite boot loop once its plugged into the usb.
[Android General] chris5s:
Have you followed instructions from the 1st post, esp part3? Otherwise Google for your os and installation of the drivers.
[Android General] petsnake:
I am working on this:

3. Install Custom Recovery

Install USB driver

This one is a tricky process.

Download SP_Drivers and extract the files.

Start Device Manager on the PC

Turn off the tablet and connect it to the PC via USB cable. Device manager will refresh and show MT67xx vcom for a couple seconds only. Quickly right click on it and select install driver manually, navigating to the directory of the SP_Drivers

Disconnect the tablet

------------------------------------------

When I plug in the tablet, it doesn't show up in device manager, even for a second, to select it for the driver installation.

I have also tried to use the SPFT to update the device. When I choose the image, all the options appear on the screen with boxes to the left of them to check off. The SPFT won't let check any of the boxes. When I click them nothing happens and I can't proceed.

Watch the Video and Use the Drivers from this thread

YOU MUST ENSURE the tablet is FULLY powered OFF when you connect it to the PC and you must use a quality USB cable.

Also use a USB 2.0 port if you have one on your PC that is.

For this bit click inside the "Location" box of the partition you want to install eg: Recovery A popup box will appear so you can now navigate to your desired recovery.img then select it and click OK. If it's not ticked already you can now place a tick in the box.

Protect_f and protect_s can be used by some applications to store "persistent" info intended to survive a factory reset, at least on some tablets like those protected by DISA.

On the subject of the boot process, do you know how to revive a seemingly hard bricked MT8127 tablet? Tried flashing the preloader and/or a full scatter backup a few times to no avail. Preloader seems intact and all, yet despite my best efforts the device is still detected as a MediaTek USB port and is stuck at that mode.

I'm on mm official update (rooted with magisk16). My sd is formatted to be used as external storage, it is shown in all explorers and works great. But for some reason the default Lenovo photo app does not save the photos in the sd and it does not offer an option in the settings to use the sd as a save location. I've been able to save photos in the sd and set it as default save location with other photo apps from Play,but they do not suit my needs (they seem to be very dark for the tablet's cam). So it seems that the sd can be used as external, but not from the photo app of Lenovo. Is this a bug of the app? Any solutions? I don't want to set the sd as internal, since I often swap it for use in the PC.
[Android General] tryfos:
Anyone please?
[Android General] Old faithful:
This is a slow thread because it's an old device for which pretty much all the possible tweaks have been tried, most of them successfully.

That being said, your question had me curious as I find the thing just too unwieldy to take pictures with and never really tried.

I'm running original KitKat rooted with all its aggravations removed and full control over the SD card, initially what caught my interest, and indeed there is no way to save to SD card, I guess in compliance with Google's then Nazi-like restrictions regarding the SD card in KitKat (users lost a LOT of freedoms then, including for some devices the right to downgrade the OS through encrypted bootoaders, but that's another battle).

Do yourself a favor and install Ghost Commander. It's the best file manager for Android and with its classic two pane interface in landscape mode easy as pie to move files around. And if you use it in Root mode with Busybox installed, no file timestamp meddling that Android is so infamously known for.
[Android General] runekock:
Maybe there is a way to symlink the photo folder to the sdcard? Perhaps link2sd plus can do it?
[Android General] tryfos:
I'm almost positive that back with 5 it was possible to save the photos directly to the sd with the default cam app.

I'm also positive that the whole problem is created by the fact that the default cam app does not properly implement the "storage access framework" of Android 6, so to ask where to save the photos when opened the first time. This is properly implemented by let's say the explorers, so they can easily write on the sd when moving files around.

I have a feeling that fixes like that https://xdaforums.com/showthread.php?t=2684188 or like that https://xdaforums.com/apps/magisk/module-exsdcard-write-access-enabler-t3670428 should work, but they're either outdated or not properly supported for MM.

---------- Post added at 09:24 AM ---------- Previous post was at 09:19 AM ----------

I have a bad experience with symlinking various folders in Android in the past and I wouldn't go that way, especially when I can easily move files over to sd with an explorer as suggested.

I just wanted to put this matter out here, because I haven't seen anyone else pointing it out. We set the sd as external storage particularly for storing photos and videos and this is not possible through the default cam app! :mad::mad:
[Android General] Old faithful:
Indeed...

I've used this hack manually implemented since day one on KitKat and it work well. No problems writing to the SD Card. But I think what is mainly missing in the photo app is simply the file chooser library. It's a very spartan photo app to say the least, even compared with my much older Galaxy Note 2. Can't do much with it, never use it except to photocopy documents on the road when there are no facilities to do so.

More about this file chooser library here. If someone could insert it into Lenovo's photo app I'm sure it would do what you're looking for. That, or perhaps something similar such as Android File Picker. Unless of course i completley misunderstood the issue ;)
[Android General] bigrammy:
Just read through your comments so thought I would check it out on my Tablet running MM.

As noted the stock camera app did not save the photos to the External SDCard /DCIM/Camera/ the folder was empty of any photos (Don't use the tablet much for photos so never really noticed before)

After a little messing around the stock camera app now saves to External SDCard by default.

Here is what I did and checked.

1. External SDCard is set as Portable Storage according to /settings/Storage & USB

2. Go to /settings/app/Camera/Permissions/ Toggle ALL off then ALL on again especially "Location" (I think that one did the trick but cant be 100% certain)

3. Open the Camera app go to settings and toggle "Store Location" off then on and grant it anything it needs.

That's it works like a charm now and saves to External SDCard by default.

Some of the above may not be necessary but just retracing my steps as said I think the Location/Store Location may have done the trick. :eek:

Let me know how you get on. :fingers-crossed:

PS: Take note of the directory structure on the External SDCard /DCIM/Camera/ If yours is different it may require you to create it.
[Android General] tryfos:
Nope, doesn't work...:( As soon as I open the app, it creates a DCIM folder in internal memory and saves there, no matter what. Are you sure you are saving in external sd and not in internal (also called sd)?
[Android General] bigrammy:
:laugh: :laugh: Please! Yeah I am sure :rolleyes:

Please read the PS in the above post as said you may need to create the directory structure on your external sdcard manually.
[Android General] tryfos:
I did just that, I even deleted the DCIM folder from the internal storage altogether. And created a new one in extsd. As soon as the app opens it creates a new folder in the internal memory and saves there...:(

Also there is no 'store location'in options of the cam app. Are you on official mm?
[Android General] bigrammy:
Is your external sdcard "adoptable" or "storage"?? according to /settings/Storage & USB

If you are "adoptable" then the default will be "internal storage" although in reality your photo's, data app, etc are stored on the external sdcard in a hidden partition which grows with demand and is linked to the internal storage it is also encrypted by default the exact same way your userdata is.

This explains things a little more in depth regarding adoptable-storage. HERE

I use my own stripped down ROM which was based on the leaked official version of MM.

I use the Official release Stock MM boot.img as this fixed the audio jack problem that was present in the leaked version.

All of this is in the MM thread for this device and you would probably get better feedback in that thread. HERE ;)

Proof for those who are sceptical
[Android General] tryfos:
My sd is set as storage.

Can you please see the version of the default cam app? Mine is 1.1.40030.

You obviously have a different default cam app version and as far I can tell you don't have the official mm rom.

I also just saw that you have the L variant, I have the F (only WiFi).

Me cam app does not have a 'store location' option,but a GPS location option:
[Android General] bigrammy:
Same camera app version but clearly it's different the "store location" on mine does refer to the GPS details but yours states GPS location so something was changed :confused:

The leaked version was for the L but I have the F tablet again it's in the MM thread.

It maybe time to root. :laugh:

Proof of camera version.
[Android General] tryfos:
I'm already rooted with magisk16 on official mm rom..

This is very strange, same app version different options? This is a mess!
[Android General] bigrammy:
If your rooted I can upload the app for you to simply replace yours. ??
[Android General] tryfos:
Let's give it a try.
[Android General] bigrammy:
Here is the Camera App and lib

It's NOT a flashable .zip so use a root file manager to replace yours. Obviously clear all the data/data for your current app too and set all permissions.

It's located in system/app on my ROM BTW.

PS: Remember to "power off" then "power on" don't use reboot.
[Android General] tryfos:
Thanks, when you say clear data in data/data, just delete all related folders of camera?

Mine is also in system/app. Which permissions should I set?

Thanks again!
[Android General] bigrammy:
Yep data/data com.mediatek.camera

Just replace the System Camera.apk and set it to.

owner = root

group = root

permissions = 644 or some show it as 0644

rw-r-r-

After the install and restart check the app permissions for the camera and allow all as in previous posts.
[Android General] tryfos:
This is getting weird, I installed YOUR app and again the setting is GPS location info!!!

Of course nothing has changed, no saves in sd... Thanks anyhow, I am now positive that this is impossible!

Do you also have a second folder in the DCIM folder named 100Andro?
[Android General] bigrammy:
No 100Andro on mine.

It must be something in the famework & or mediatek res then :(
[Android General] tryfos:
Perhaps magisk has something to do with it, but I'm not willing to dig any further...I give up!

What about battery times in 6, sot and/or standby? I think it's worse than in 5. Mine consumes almost nothing in sleep mode, especially when I turn wifi off. But during normal use (browsing, some apps, no games) the drops in percentage are rapid (12-15% per 1h sot). Is this normal? I think it wasn't like that in 5. I recently changed the battery for this reason (I thought it was dying), but the results are the same.
[Android General] bigrammy:
There are no battery issues on MM.

Battery usage is subjective and has way too many variables to discuss here but here is a "General" quick list of things to check when anyone is upgrading or downgrading.

1. Did you do a clean install? (this means a full wipe of all userdata, cache, dalvik cache etc and no previous android version restores!)

2. Number 1 above is very strongly recommended but as a consequence of that you need to allow time for the ROM to settle in and rebuild the new data, cache logs etc.

Give the ROM a few days of normal use before judging it's battery performance. This applies to any ROM on any device and any version up or version down.

3. App's. Recently installed app's which may of been fine on a previous version of android may not work so great on your current version so do your research regarding those and see if anyone else is reporting issues.

4. Xposed!! Using it? If so go to the xposed threads rather than coming to the device threads to complain about something which is likely a direct consequence of a xposed module.

(I and likely many others have spent hours and hours of time trying to reproduce faults to help people who do not declare they are using xposed :mad: This is the most annoying thing ever so if ANYONE is using it and wants help DECLARE your using Xposed.!! Other Xposed user's may have the answer to your problems and will be better placed to help you. )
