Managed to get cwm and root with this guide: http://forum.xda-developers.com/and...vo-a3500-h-t2879208/post55491817#post55491817
Modified the guide for Lenovo A3500-FL!
EDIT: Also some users have reported that this guide doesn't do the trick or is out-dated, so copypasted the guide from this post here.
Guide
1. Download attachment cwmRecovery.zip and download latest Flash_tool (version 5.1352.0) can be downloaded from here)
1.1. Enable USB-debugging. (How to do this)
2. Manually install the drivers from the attachment a7_40_drivers.zip for the LenovoTablet before plugin it to computer (win7 dirvers work for win8 too).
2.1. To install unsigned/uncertified drivers on Windows 7: http://en.kioskea.net/faq/3914-windows-7-how-to-install-unsigned-drivers
2.2. To install unsigned/uncertified drivers on Windows 8: http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/
2.3. After you have disabled the driver signature verification, you can install the drivers like this: Right click My computer, Manage, Device Manager, right click your computer at the top, Add Legacy hardware, next, Install plapla manually, next, Show all Devices, Have a Disk.., Browse to the driver folder where you unzip them, choose example windows7 and the 64 version (win7 drivers work for win8.x too), install every device. Then follow the guide.
(Note: Otherwise Windows only installs the normal automatic drivers and its more difficult to install the other drivers.)
2.4. Plug your device to PC.
3. Download the latest supersu zip file (version 2.46) from attachments or from https://download.chainfire.eu/696/SuperSU/
3.1. Move the zip.-file to the Sdcard.
4. Turn off your device.
5. Unpack cwmRecovery.zip
6. Run Flash_tool.exe with Admin Rights.
7. Chose Scatter-Loading and choose MT6582_Android_scatter.txt (in Recovery folder).
7.1. Now you will see checekd only one checkbox - recovery, if not click on it and choose recovery.img
7.2. Press Download.
7.3. Connect your device.
7.4. Wait few seconds.
8. Have CWM on your device .
9. Unplug your device.
10. . Boot to cmw recovery by turning off your device. Then press and hold VOL DOWN + VOL UP and then also press and hold POWER for about 7 seconds.
10.1. Choose " Install zip from sdcard." (To confrim always use the Power Button)
10.2. Choose "zip from sdcard".
10.3. Select SuperSU-v2.46.zip from sdcard and apply.
10.4. Have a rooted tablet.
It might be necessary to always flash the CWM with the Flashtool directly before you startup the device. Otherwise it will start the original AndroidRecovery again.
It might also be necessary to use different drivers from here.
If the supersu zip doesn't install, try toggling the signature verification to disabled from cwm->install zip from sdcard->toggle signature verification.
Tested and working on Levono A7-40 3500-FL with kitkat update, build number A3500FL_A442_01_25_140823_SE, from ota. Attached screenshot for proof. Also other people have reported that this works for later updates too, for example A3500FL_A442_01_27_141127_SE.
You can update to the latest OTA firmware by first going back to stock recovery. See the second post for the guide.

How to go back to stock rom/recovery and update to latest Lenovo OTA firmware update
So, it's pretty simple, you take the stock_recovery.zip from the first post, extract it, and replace recovery.img in the recovery folder with the stock one.
Then :
Quote:
4. Turn off your device.
6. Run Flash_tool.exe with Admin Rights
7. Chose Scatter-Loading and choose MT6582_Android_scatter.txt (in Recovery folder)
7.1. Now you will see checekd only one checkbox - recovery, if not click on it and choose recovery.img
7.2.. Press Download
7.3. Connect your device
7.4. Wait few seconds.
And that's it !
On a side note, if it seems stuck on a black screen with a loading circle after factory reset, you have to put the tablet in landscape mode and restart (the shutdown menu appears without any problem) - this issue doesn't seem related to recovery, but a bug within lenovo firmware and the first configuration screen.
Side note 2: The first boot after flashing new update might take 15mins.
Side note 3: After updating to the latest OTA you can go back to cwm recovery with the guide from the first post.

I got the same tablet and I also am looking for a root. :/
Another waiting for rooting lenovo owner.
Same here, i was looking for a root guide and i couldn't find anything.
Does anyone else has a problem with long charging times?
Well it charges long and the charge stays long, so no issue here.
Seems that not that many lenovos root easily, but of course this is a pretty new device(?).

Installed everything and tried vroot once again (I have tried it before).
Still not rooted. And btw that vroot at least tries to install bunch of bloatware crap on the pc.
Edit:
I would suggest for anyone who installed Vroot to your pc to scan the whole pc after you uninstall the vroot.
Here are the scanning tools:
Malwarebytes
adwcleaner
superantispyware
hitmanpro

I got a successful root by flashing Recovery.rar from lenovo-forums.ru, (it's easy to google, I'm not allowed to post links) with the included SPFlash Tool and afterwards flashing the needed SU binaryies and apk. However, this will mess up the OTA updates, and I can't find the stock recovery again.
Therefore, I really beg anyone having the stock recovery to post it, enabling us to switch between them, whenever we want to apply any OTAs.
Thanks a lot!

Well I very highly doubt that there will be any more updates for a device with this price range. And since the next android version is the L version, which requires more work than before.
Edit2: http://forum.xda-developers.com/android/development/guide-lenovo-a3500-h-t2879208 found this. Tested and it works. Will edit it to the first post.
The same as me
i cant flash update.zip from cwm recovery and need to restore the stock recovery ...
I think flashing the stock rom can solve the problem..
.by using the sp flash tool we can select to flash recovery only ....unticking the others except recovery.img ....you just try to download the stock rom and flash the recovery
Same problem
Heya guys!
I have the same problem here.. I can't run the .zip file from the SD card, it get interrupted every time. Any ideas?

I dont know what you two are trying to do but this thread is about rooting the lenovo A3500-FL not about lenovo stock rom.
Rooting..
Yes indeed, that's what I'm trying to do. Rooting the A3500-FL. According to the instructions you need to install the SuperSU from a zip on your SD card. When I try do that it gets interrupted every time. Installing recovery went well. So I'm not getting what I do wrong? Any ideas?

Yup.. This is the problem. The recovery runs fine from Flash Tool and claims it installs it. (Download ok) But I still don't seem to have CWM on the device. It's just normal recovery mode. So any ideas about the CWM-installation? What could possibly go wrong? I get no error messages. Cheers.

I was following guide from this thread.
"http://forum.xda-developers.com/moto-x-play/general/untested-how-to-root-moto-x-play-t3211941"
I did everything step by step, bootloader unlocked and once phone get started too then after flashing twrp i was not getting anything when i tried to reboot twrp asked to install supersu and i installed it.
THen i read somewhere don't install supersu when twrp asked ?
then i did process all again, but can't go through warning message of bootloader.
Please help i just want to root, don't want custom rom or anything.
did you take a backup ??? if you did restore it. otherwise do a factory wipe from twrp if it does not help Then download twrp flashable marshmallow stock firmware and flash it.

Can anyone give me link to stock firmware ? Indian version i was on Marshmallow. & how to flash stock firmware

download from here forum.xda-developers.com/moto-x-play/general/rom-xt1563-brasil-stock-6-0-twrp-t3272979
if twrp doesn't detect the backup then connect the device to a PC in fast boot mode and type command "adb devices" it will show you your device id . now take out your external sdcard go to twrp backup folder and make another folder inside backup of the name of your device id and keep the backup there and then restore from twrp.

It takes good 15-20 Mins at Moto Logo; Wait patiently and if it refuses to boot after that then do this :
Download latest TWRP and flash it. DONT FLASH SUPERSU from TWRP when prompted at boot.
If this does not solve either, download Android 6.0 + TWRP from this Link
Save it to TWRP \ Backup and then boot to TWRP, Restore and Boot as per instructions in that forum.
If this also fails, then simply flash FULL STOCK FIRMWARE from here and follow instructions given at here.
Android N Preview 2 npc91k (flashable & image with no encryption and dm verification)
This thread is for the second Android N Preview.
For Android N Preview 3 see: http://forum.xda-developers.com/nexus-6/general/android-n-preview-3-beta-npd35k-t3381845
For Android N Preview 4 see: http://forum.xda-developers.com/nexus-6/general/android-n-preview-4-beta-npd56n-t3399473
** DISCLAIMER: I AM NOT A DEVELOPER. I DO THIS AS A HOBBY AND SHARE MY FINDINGS IN CASE SOMEONE ELSE FINDS THEM USEFUL. **
** THIS WORKED ON MY DEVICE BUT IT MAY NOT WORK ON YOURS. APPLY AT YOUR OWN RISK **** The following are instruction for installing Android N Preview 2 image released by Google on 4/13/2016. After the installation you will have TWRP recovery 3.0.2-0 with the data partition erased and unencrypted if you use method 2, which means you will have ~ 3GB more space and ~ 10 seconds faster boot speed **Always backup your data before flashing something a total stranger gives you!
Method 1: Flash update through TWRP recovery (keeps your data and current recovery)
1- You need to have TWRP installed on your phone.
2- Download this flashable zip..
3- Copy to the phone internal storage and flash via recovery.
4- Reboot. Your data should still be intact and your OS is upgraded to N Preview 2. If your internal storage is unencrypted before flashing it remains unencrypted.
For some people this didn't work. It seems to be the case when you have been encrypted by your previous Android N installation, in which case TWRP seems to have difficulty reading the file, and that seemingly Preview 2 doesn't play nice with TWRP. It works best when you are unencrypted and your recovery is 3.0.2-0. Thanks to @gammaxgoblin, @blitzerking1, @Michael in ATL, @HueyT, and @PhillyFlyer for debugging and hints.
Method 2: Flash update using a computer (wipes everything, unencrypts data, and upgrades TWRP)
1- ALL of your data including the internal storage will be lost so make a backup. (If you know what you are doing and you are coming from unencrypted Marshmallow you can modify the instructions to not lose data but I won't help you with that).
2- Download this file. Note that it is NOT a flashable zip.
3- Unzip into a folder of your choice on your PC.
4- Open a command window (cmd) and cd to this directory. then run the following:
Code:
flash-all
5- Wait until prompted, then press key to reboot the phone.
6- Your data is wiped and your OS is upgraded to N with unencrypted internal storage. Your TWRP is also upgraded to 3.0.2-0.
Technical details: this is a repacking of the Google image with a modified Kernel and removed userdata and recovery images. Everything else is stock.
Problem downloading from Mega on a mobile browser? Change the page setting to "Request desktop site".
About root and other issues
To obtain root after installing this update you should flash SuperSU 2.71 (or higher) in recovery. Get it from here: http://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133. Despite the fact that SuperSU 2.71 is supposedly re-written for Android N, there are still some apps that seem to have a problem obtaining root. The commonest complaint on this thread so far has been about Adaway. If you want to block Ads just manually do what Adaway does. Download a hosts file from any ad block list server such as http://winhelp2002.mvps.org/hosts.htm, copy the files on your sdcard, boot the phone into recovery, and using the TWRP file manager replace the file /system/etc/hosts with this file and set its permissions to 644 (rw-r--r--).

Same error for me as well. I can extract the zip and view the file it is talking about. I also tried on TWRP 3.0.1-0 and TWRP 3.0.2-0
Everything is working perfect for me with the new zip. I have a unencrypted phone and used 3.0.2 TWRP.

Seems like TWRP is having a lot of troubles with each version of N Preview's encryption. I have same problem with both N6 and N6P, as do others in that forum too....:/

Just to help with the installation of method 2, holding shift and right clicking a blank space in your unzipped folder, you can click open command window here. That will save you having to CD all the way to it.

I did method 1. It upgraded fine. All my data remained. It killed root (expected this) and my TWRP. I was unencrypted before attempting.
I went and downloaded the latest TWRP and flashed via fastboot. Then downloaded latest SuperSU from http://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133 and flashed it via my newly installed TWRP. Root confirmed and all is well.
Good to go Thanks!

You may have to flash a previous stable release of marshmallow or lollipop from Google first and then try this because something seems to be corrupted in your system.
Today, I installed TWRP and rooted my device. I tried to install Xposed but I couldn't get passed the logo screen after rebooting. To try and fix this I did an advanced wipe and got rid of everything...
I know this was very stupid! TWRP is telling me there is no OS if I try to reboot. Is there a ROM I can install to fix this? I was on the stock MM rom and have L31 version.

I made the same mistake at some point, but managed to get it back up and running.
Download the correct version of "update.zip" for your phone.
In my case it is a L31C432 so I looked for a file called something like VNS-L31C432B160 (stock MM).
Download this (EU version) (if you have a L31C432)
Once the download is completed, rename the downloaded file to "update.zip".
While in Recovery on your phone, and it's connected to your pc, copy the "update.zip" to either the phone's internal memory or the sdcard (doesn't matter).
Grab your phone and go into "Install" in your recovery and find your "update.zip" file.
Slide and let it install it.
Once done, reboot.
Viola!
Remember the "Thanks" button if it helped :good:

The final steps to Remove "Vendor ROM" that does not have the Update Option in Settings Or Unbrick Le Max 2 or simply Update Le Max 2 to latest EUI.
NOTE: This method should address the following weird problems:
1. Le Max 2 TWRP Seeing 0MB in Internal Storage. Unable to access the ROM Storage
2. Encrypt Option Greyed Out In Settings-->Fingerprint and Security
2. Update Option missing in Settings.
3. Fingerprint Sensor not working... If it still gives trouble... Calibrate the FP Sensor in its settings. Or register the same fingerprint multiple times.
This method should work on ALL versions of Le Max 2 including X820 X829 X821
Before starting... Remove ALL USB peripherals that might interfere with the process. Use USB Ports on the PC/Laptop... DO NOT use USB Hubs... Even if the phone appears dead... Connect it Power Outlet and let it charge for an hour.
1. Download the latest Stable EUI... from LeEco Website Directly .
2. Download the FlashOne v1.9 And Service ROM From HERE.
UPDATE: FlashOne v2.0 has been released! Here's the LINK.. It is a bit more advanced and offers the ability to format User Data for a Cleaner Flash
3. Download Qualcomm Drivers
4. Put Le Max 2 in EDL (Emergency Download Mode) by pressing Volume +, Volume - and Power Button Simultaneously. For those having difficulty..... Here are few tips.
Connect the Phone to PC. If the phone is Switched/Powered On... Then Power Off the phone and Switch Back On with the Key Combinations.
OR
If the Phone is Switched Off... Then Use the Key Combination to put the phone in EDL Mode..
In either case..... the PC will make a sound of Disconnection and Reconnection of an USB peripheral. AND you will see Qualcomm QDLoader 9008 Driver Installation. To verify the same... go to Device Manager in Win 7 / Win 10 and Under Ports (Com & LPT)... you should see Qualcomm HS-USB QDLoader 9008 (COMXX).. The XX corresponds to a particular COM Port. Remember this port.
5. Once the Le Max 2 is in Qualcomm QDLoader 9008 EDL Mode... Start the FlashOne Software.
6. Choose “Qualcomm – flash dead phone” from the drop down menu next to “Flash type”.
7. Click “Refresh button” next to “Select Device”. Here your Le Max 2 will show up but in COM Number (ComXX)
8. Browse for our Qfil/service ROM by clicking “Select File”.... You can technically select the Latest EUI ROM... But it is safer with Service ROM. DO NOT Unzip the ROM File.
9. After everything is set up under “Settings”, Press “Flash” button.
10. Installation can take anywhere between 10 to 20 minutes. Have Patience.
There are chances that the Flashing might fail. In case it does... Simply put the phone in EDL Mode again... and restart the procedure.
11. After the FlashOne confirms successful flash... Wait for 15 - 20 seconds. Then Power On the phone by pressing the Power Button for at least 60 seconds. Do Not Panic due to the long press.. Press it until the phone vibrates.
12. The Le Max 2 should be in Developer Version of EUI with an unlocked Bootloader and STOCK recovery.
13. The Developer ROM has the “Format Virtual SD card” setting in Settings Menu--> Backup/Reset--> Factory Reset.. Use the setting to get back the 50+GB
[You can also use the option Format Data in TWRP Recovery instead and the partition will 64GB correctly instead of 10 GB initially. Read ahead for the procedure]
14. Once you have a working Le Max 2... there are two directions:
Install Latest Stable EUI ROM... with Update Option
OR Install TWRP Recovery / ROOT / Custom ROM
15. a. For those who wish to install Stock ROM... Simply rename it to "update" (DO NOT Add .zip... Else the file will look like update.zip.zip) and place the update.zip file in ROOT of the phone. Thereafter Switch Off the Phone... Enter Recovery by pressing Volume + and Power Button... Choose Update System AND the other setting to Clear All Data. Your Le Max 2 should update without any error.
15. b. For those who want TWRP and ROOT:
* Download the latest TWRP (For Le Max 2) and SuperSU from their respective websites. Download and Install ADB and Fastboot From HERE.
* Copy the SuperSU Zip File to the ROOT of the Phone.
* Unzip and Rename the TWRP recovery to Recovery (The file should be Recovery.img.... NOT Recovery.img.img)
* Put the Le Max 2 into Fastboot Mode By Pressing Volume - and Power Button
* Go to the ADB Install Folder and Press Shift & Right Click to get & select “Open command window here“. Confirm Fastboot is working by Entering Command: Fastboot Devices.. You should see a random string of letters followed by the word Fastboot. If you do not see the same..... the installation didn't complete successfully.
* In the Command Window.. Type: fastboot flash recovery recovery.img
* Enter the following Command: fastboot boot recovery.img
* Once the Phone has entered the Recovery... Flash the SuperSU Zip file and you will have ROOT capabilities.
* Take FULL Backup of your device and then install ANY Custom ROM.
Do let me know your results.
[Update]: There's a simple method you could try to get the Update Option Back in Le Max 2 Phone that arrived with Vendor ROM... Using the default File Manager Tap on the Update.zip file and select Upgrade Option. This will force the phone to Update using the ROM file. This method is for people who could not update through the Stock Recovery and received Errors.
After QFil/flashone my lemax2 still bootloops. I've tried flashing other roms via recovery but it reboots mid installation.
Any advice?
Try Another QFil / Service ROM

My advice is try another Qfil. These files are quite large and hence the one you downloaded might have some corruption.
Try THIS File
Hi, the link to the Leeco website is down...is there any alternative for downloading the latest stable EUI?
I downloaded the 23s from another website, renamed "update" but when I try to update via recovery it fails, cause: corrupted.
Any suggestion on this?
Thanks a lot in advance

You may try to use twrp to flash it, you downloaded version is a twrp backup version...
Thanks for the suggestion but I'm trying to get back to stock for other phone issues... So I wanted to avoid to install twrp, if possible.
Any link to a stock rom that can be updated via stock recovery?
You know I just going to blame Android 7.0 Nougat any chance we can have a CyanogenMod 13 6.01 based foxfi friendly ROM ?

I used the 23s from this link: https://bbs.le.com/zt/eui/le_max2.html
I flashed it from an indian rom. It will change your bootloader to chinese, though (not really an issue). And your recovery too, I guess (don't panic, it's bilingual). It will also update /firmware, and that should help with many issues.
However, there's no need to flash TWRP in order to use it: you can just boot it ( fastboot boot TWRPname.img).
At the last step, my indian rom is not getting flashed. Saying corrupted!!. Yesterday I updated with the same (rom) file from the system updater when I did not root the device.
"[Update]: There's a simple method you could try to get the Update Option Back in Le Max 2 Phone that arrived with Vendor ROM... Using the default File Manager Tap on the Update.zip file and select Upgrade Option. This will force the phone to Update using the ROM file.

Following these steps got the same error.
Edit: I am pretty much sure the developer chinese rom has the issue. It does not let you update with the Indian rom. Pretty bad.
Did anyone succeed to flash the indian rom the phone came with, or any indian rom from these chinese developer rom?

I do have problem (see the post right above). Any Ideas?
Ok so, I did as shown in the topic : https://forum.xda-developers.com/le-max-2/help/flash-eui-rom-fastboot-t3525831
download twrp (The one I know didn't had the touchscreen issue)
boot from twrp (wish I had know about it before!)
upload zip file to /sdcard ( here's the catch, while in TWRP in don't have access to adb, the phone doesn't connect to pc or I don't know even I mount it, could be me. So i just put the archive at the root of the phone before booting to twrp from adb)
install rom
reboot
And ... it's ****ING WORKING!*
Really big thanks to ThE_MarD for his help!
HI, i hv the same problem likes yours with split screen.
Possible to share the steps how you manage to solved it.
Update:
Hi, I just managed to resolved it.
Download the given recovery 19S and save it on a USB drive.
Run twrp and press button wipe as our screen is reversed.
Then look for the file at external drive USB.
Just install it and once it is done..... the screen will return to normal

Hi.
Yes. After "QFIL", i also didn't update my device from DEV ROM with any Stock ROM (Indian or Chinese versions) by "upgrade.zip" without get the "corrupted file" error. So by TWRP, i installed 16S Indian Stock ROM -- TWRP informed that i have "no OS installed" but i proceeded and restarted from TRWP. It initialized the new ROM, and after the first setup, i restarted the device to complete any system operations after the first boot, and i updated the device with the Indian 19S with the EUI updater ( tapped "upgrade.zip" file). The device now have the stock recovery and boot in english (not chinese), and the EUI in all languages available on "India 19S Stock ROM".
Stock ROMS:
Le Max 2 All Official Stock Firmware links
Best regards.
