Owe you a couple of ?!
No, you don't :) it's a pleasure for me to provide a little help :highfive:


Edit: yeah, magisk is a different story... Basically rooting with the possibility to apply different mods in module Form, reminds a little of xposed but is a different concept with different possibilities, I decided to use supersu too because it's absolutely reliable, magisk only works 90% flawless, titanium backup won't find root permissions when every other app does, little weird...

Got my new devise!Just one disadvantage: because it's 8" and with a metal back cover,t's heavy!
Now I'm drawing the battery to make two cycles of fully charging and fully discharging.
Will install RR on A3500HV in a couple of days!
This device runs Nougat-7.1.1!Not bad but it's $200 here!
Recommending!:cool:

How to Port mtk6582 roms for lenovo a3500
Sorry my bed english.
We need AndImgTool, notepad +, winrar or similar programs.
1. We unpack the firmware
2Pack the kernel with andimgtool
3 We change the folder portkernel to the stok folder kernel (if the firmware does not reach the boot animation in the ramdisk we change port uevented.rc to the stock uevented.rc
4 We pack boot.img (do not forget to rename new_boot.img in boot.img)
5 We are looking for the updater script and changing the lines with notepad +
format ("ext4", "EMMC", "/ dev / block / mmcblk0p5", "0", "/ system");
mount ("ext4", "EMMC", "/ dev / block / mmcblk0p5", "/ system",
mount ("ext4", "EMMC", "/ dev / block / mmcblk0p8", "/ data", "");
6If the firmware does not want to be installed (some symplinks falled) then we take updater binary and updater script from cyanogen mod13 from Kit-kat
7system-lib replace libmali.so from cyanogenmod 13 in port firmware
8system-lib-hw replace
hwcomposer.mt6582.so and graphlock6582 with replacement.
9Pack the firmware.
If the firmware hangs on the bootloop, then we drop the graphlock8xxx and hardwarecomposer 8xxx files into the system-lib-hw folder (these are in the official firmware 4.4.2)
Files for port rom take from cyanogenmod 13 from the cicadata.
To turn off the tablet when bootloop it is necessary to clamp the buttons power + keyplus + keyminus and press into the round hole for about 4 seconds (I use a needle).
This works when porting from the kernel 3.467 to 3.467
it can be ported from any mtk6582 device theoretically possible and with mtk6737,6735 just x32bit system except (sprout).
Do it at your own peril and risk.

How to Port roms7.1.2android from mtk6572 for lenovo a3500

1 unzip boot.img
2 Move stok to to boot.img (sometimes
stok uevenced.rc if the firmware does not start.
3Pack boot.img
4Change the updater script values
mount, format (look at cyanogenmod13) if you see an error in recovery (some symplinks falled), then move with the replacement updater script and update binary from cyanogenmod13.
4 Copy with the replacement libmali
5 (Very important) Copy grallock.default, gralloc.mt6582, hwcomposer.mtk6582,
Open gralloc6582 and hwcomposer6582 with notepad +.
Find all the values ​​of 6582 and replace them with 6572.
Then rename gralloc6582 and hwcomposer6582 to gralloc6572 and hwcomposer6572.
5 Copy to the lib-hw folder gralloc8xxx and hwcomposer8xxx (they can be found in the official firmware).
6Pack the firmware.

Hi Sam!
How many 12 hour charging cycles do you do when you buy a new device ?
Some say 3 , but I usually do 2!
Best regards!
LOL :laugh: non as all devices nowadays usually use Lithium-Ion or Lithium-Polymer based batteries where no memory effects can be observed - the practice you do was true for the 1st generation accumulators (NiCd - Accumulators) but with the modern ones the only real danger is to regularly drain the battery completely to zero or to not use it and having it just laying around for months, that's things which shouldn't happen on a regular basis but otherwise fear not - a battery should easily last 2 years and more depending on your usage, I own a Samsung Galaxy Tab 2 10.1 (which has official lineageOS support) from 2013 and it's battery is still great, despite I never changed it in about 5 years and my doughter uses it daily...

Muchas Gracias,Sam!:)
Yup,Nickel Cadmium batteries are gone but I have Lenovo A3000H besides my Lenovo A3500H!Their batteries last two hours despite all calibrations I made!
But thank you!

What? Are you on mobile network all the time?
Cause I usually get around 4 to 5 hours screen on time on my a3500-fl, of course on WiFi only as it has no SIM available...

Well then I'd should be just fine, i already posted a link - check this :) have a nice day!
https://forum.xda-developers.com/android/development/guide-lenovo-a3500-h-t2879208/post73473559 and remember to use 7.x gapps for i9305...
Hi ,Sam!Since after the dirty flash of Lineage OS my device got unstable,i had decided to flash RR5.8.4 and I saw you are the developer! Good job!
But because it was in in a beta 3 version,I did a clean installation of Lineage OS.
It's much, much better!
One thing I don't understand: my internal storage is 16 GB but the system files take 12GB of it while on my new Lenovo which runs 7.1.1 ,the system files are 5,5GB.
Should I flash the ROM again with wiping the system partition too?
By the way,it was not a problem to recover all applications of mine because they were synchronisated with my Google account.
Thank You in advance and looking forward to a stable RR5.8.4

Best regards!:)

lol :laugh: no I'm not the developer of this, the guy who ported this is lolpro100 from 4pda.ru, he ported this rom from a team called "liquid porting", they actually developed it and built it from source for acer Z500 and he ported it to the a3500s, I honestly got nothing to do with it, just shared my findings as I was myself searching month for usable custom software for this device, all credits to those guys, definitely...

That's not normal and should be more like on your other device, system should be around 4GB, I usually wipe system before flashing but it should get wiped anyways by the installer script, maybe from your strange partitioning for link2SD?

It's a bit off topic but which file manager do you use?
I use TOTAL COMMANDER and will remove the built-in ES file manager!
It's sluggish AF!
Have a nice afternoon!

A TWRP update is available :) you can flash it by your already installed TWRP (INSTALL, press install image, choose TWRP 3.1.1, SWIPE, choose recovery partition, swipe and use TWRP reboot option and reboot to recovery, done :)

Installed it yesterday,Sam!The reboot function really doesn't work but in general it's better!
Also downloaded & installed the file explorer You recommended me!
I like it!
You are my tutor in Android although I enrolled in a course at Google.

Best regards: Jimmy?

I have flashed the new TWRP image but haven't used it yet, so I didn't know about reboot function, maybe it's going to be fixed, Idk, remember you can revert to the other version the same way you updated to the newest...

You're absolutely welcome :highfive:
