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.

Cant install a Costum ROM

Greetings to everyone,
I would be happy if you can help me with a little problem on my Note 4.
For some reason I cant install a costum ROM on my Note 4 (N910F).
As soon as I have installed a ROM like NameLessROM the phone reboots, shows the Samsung logo for about 10 seconds, reboots, shows the logo, reboots, ...
Its the same thing happened to me once whileI tried to boot it with no system partition (wiped it)
I am using the newest TWRP.
Anyone got a solution?
Greetings
Robin

Sorry Robin for "hijacking" your thread but we're in the same boat
I'm having the exact same problem with my SM-N910F.
I've rooted the device using Odin3 and "CF-Auto-Root-trlte-trltexx-smn910f.tar.md5". This thread: http://forum.xda-developers.com/note-4/orig-development/sm-n910-cf-auto-root-t2897428
That went fine and I checked the root privillige afterwords with a terminal app on the phone. I issued the SU command and got at .....root#. Don't know if thats the right/best way to check it!
After rooting the phone I still had the stock recovery tool so again with Odin3 I installed "philz_touch_6.59.0-trlte.tar.md5".
This also went fine and I can now access "PhilZ Touch 6" recovery tool.
From here I've tried installing three different ROM's ("GlamourS6v3_1", "Super.Fast&LolliFamous™[S6+Style+v2][PART.4.0.]_BOC3" and "Super.Fast&LolliFamous_[.PART.6.0.]_BOD2") but keeps ending up with a phone that just keeps rebooting.
When I install the ROM I start with the "Clean to install a new ROM" option and after that install ZIP. The ROM's are located on my SD card.
The installation succed and when I reboot the phone just continues to reboot.
Any good advise?
Regards
John

You have to flash via odin the right modem and bootloader for the ROM that you're trying to install

mone, your a genius! Or maybe you just read the instructions more carefully than I did
I found the exact info and links in the ROM thread and everything is working now.
Thanks!

Okay for Nameless ROM to work on N910F you have to install the SimplKernel and need to update your bootloader and modem accordingly.

If I''m not mistaken your phone model is N910F, if so you are flashing the incorrect ROMs as the ones you listed are for the exynos variant. So please look for ROMs in the correct thread "Galaxy Note 4 Android Development (Snapdragon)" And using PHilztouch recovery is not recommend and so I would advise you to install TWRP,
N910F = Trltexx
N910G = trltedt
Exynos:
N910C = treltexx

Rooting A5 2016 marshmallow

Hello guys,
I really want to root my a5 2016 running on marshmallow but every thing fails.....Kingroot fails, kingoroot the same and when i try to do that with cf-auto root it says that flashing passes but "recovery is not seandroid enforcing".... I have ticked the oem unlock and the usb debbuging but still nothing....The only way to get my phone back working is to reflash the firmware that i had (the official marshmallow) but then it is not rooted!!! If anyone can help i would really appreciate it...
Thanks

i ran into these problems also, autoroot not working etc. and managed to fix it like this :
- Reminder but very important : as you mentioned first of all make sure oem settings is still enabled in settings/developper settings
- Flash TWRP for marshmallow with the NEWEST Odin, i used Odin3 v3.12.3 (my older version did not make TWRP stay after reboot, i tried like 10 times)
When you have twrp installed download UPDATE-SuperSU-v2.76-20160630161323.zip (or use the one from my attachment) and flash it, if root is not available from first try, flash again, i had to do it 2 times also.
I hope this works for you too

Root, recovery and custom rom setup for Galaxy S5 (SM-G900I)

Hi all,
How are you?
I've been looking at these forums for most of the day, though am still quite confused. If someone could assist to clarify it would be much appreciated (as I would like to avoid to brick my phone).
I'm currently running Stock Android, Marshmallow version 6.0.1 with the 1 November 2016 Security Patch.
The model of my phone SM-G900I (Australian edition).
So I've come across the following links with the instructions on how to root and install recovery, though quite confusing.
http://forum.xda-developers.com/show....php?t=2699648
Recovery Query?
I understand that you need to download the Samsung Drivers and Odin.
I've downloaded the TWRP files for my phone - twrp-3.0.2-2-klte.img.tar and twrp-3.0.2-2-klte.img.tar.asc
Do I need to use the twrp-3.0.2-2-klte.img.tar.asc file at all?
Root Query
Is the towelroot method of rooting the S5 still relevant. The reason I ask, is that when I had posted an initial question on the XDA assist, I was advised that this may not work.
If the towelroot method is no longer relevant, would the CF-Autoroot method below work?
http://forum.xda-developers.com/show....php?t=2696537
If neither of the above methods work I have seen mentions of "flashing root" via TWRP.
Are there any known instructions on how to do that on XDA or any other website?
Or is it just a matter of obtaining the superSU zip file from https://download.chainfire.eu/696/supersu/ and flashing it?
The other information seems straight forward re using the Samsung Tool to backing up the device and the EFS .
Any help would be much appreciated.
Thank you.

just flash the .img file in download mode, and dont use the asc file at all. also dont use twrp 3.0.2-2, just use 3.0.2 (not 3.0.2-1 or 3.0.2-2 as they can be pretty buggy). Towelroot has long since become irrelevant back in the 5.0 days unfortunately so all you need to do is find the appropriate supersu.zip file and put it on your phones sd card (either internal or external), boot into recovery an install that zip via TWRP then reboot. Should be good to go. The classic "root via recovery" method

1. Plug in your phone and let the drivers load.
If phone unrecognized then head to Playstore you can find loads of apps for drivers
2.unplug your phone and turn it off
3.Load odin.
Some versions of Odin are outdated. So watch for that.
4.Holding your turned off phone. Hold the volume down power and home buttons. Done correctly it should bring you to a page saying custom Roms can damage your blah blah. Volume up to continue down to reboot. Plug your phone in then Push volume up if you feel ready to Join us Oh Padawan.
Now I am sorry for the lengthy information, most likely you have already gotten to this point, but I just want to make the same page for you and future readers. No point in asking a bunch of potentially irrelevant questions when one explanation is sufficient.
5. Odin should find your phone which will be represented by a lit up colored square on the left side indicating a Com:value# which number is of little consequence just tells you which port it found it at. Do not dwell on this.
6. Using an extraction program such as .7z take your CF auto root .Tar file, not the .Asc, and extract. You should be able to find an file with ap in the extension.
7.Take the path from the URL bar of this window including the name of the ap file and copy it over to Odin. In Odin you will see the place to put it is represented by AP.
8. CLICK START AND WAIT WITH JEOPARDY MUSIC.
9. IT MAY REBOOT A FEW TIMES BUT UNTIL IT SAYS success OR FAIL IN ODIN DO NOT TOUCH.
10. Repeat steps 7-9 for twrp.img
10. Now taking this was a success turn your phone off. Unplug and holding volume UP power and home Gets you into twrp recovery. If all is well you can reboot into system. Ignore the kernel warning.

^^^^^ theres the long explanation LoL ^^^^^^^^ i disagree with step 9, but meh

Hi all,
Thanks for the detailed instructions.
So it appears that you can perform the task in 2 ways, ie
* By initially flashing TWRP first using Odin (whilst phone is in download mode), then running the TWRP and then copying over the supersu file to the sd card, then flashing this.
Or alternatively, following the above steps which first
* roots the phone by using Odin within download mode and the "cf auto root" file. Then once again using odin and flashing the TWRP file via odin.
This is my understanding.
Please let me know if I've misunderstood, otherwise thanks all. I'll be giving it a try soon.
My eventual goal is to install the Resurrection Remix Rom, so fingers crossed.

the cf auto root file usually isnt necessary, nor is flashing supersu really as the newer twrps have the root function built right in. Itll ask you if you want to enable superuser rights the first time you boot into it. Just swipe right and its rooted. Alternatively, flashing supersu from within twrp or the cf auto root also work. CF is the acronym for the dev ChainFire, he is the man (or she, and conversely "the woman" or whatever LOL)!! But the crux of what you need is twrp installed, from there youre usually set. Get rooted, make a nand of your stock setup and flash away. Also, id make sure to download the stock tar.md5 file of your phones firmware in case all goes awry (or to hell in a handbasket or enter clever euphemism for stuff going bad here) so you can flash the stock tarball in Odin if you get stuck in an endless bootloop and your stock restore file doesnt work. Also, when resoring from AOSP to TouchWiz or vice versa, does require a few boxes to be checked for it to work, but it happens all the time. Happy flashing and feel free to ask away if you run into anything man!

Thanks all for clarifying.
I did have some difficulties along the way though I did successfully install twrp.
So I downloaded one of the latest versions of odin on mums computer. Laiche the twrp tar file in the ap section. Loaded it then restarted the device. Ran recovery though it was still the default android recovery ie it appeared as though nothing had changed. I looked at another forum which suggested to turn ooff the auto reboot option in odin and perform a battery pull and then launch directly into twrp. This actually worked after much agony.
I then loaded a superuser zip and flashed it onto the phone.
Rebooted confirmed that the phone was rooted.
I then relaunched the twrp recovery and ran a nand? backup of my device. Then I attempted to install a custom rom ie resurrection remix. Unfortunately it did load though the screen appeared to freeze after boot and was therefore unusable. Thank goodness the restoring of the backup worked.
I'll reattempt the installation of a custom rom very soon. Fingers crossed.
Thanks.

May have installed twrp on wrong way... now my 330nu Tablet freezes on Samsung logo.

Okey people... i'm going to tell you what I was doing and what happened:
1 step I downloaded Kingroot for active Root
2 step I downloaded TWRP apk on my 330nu
3 step I flashed "milletwifi_boot.img" on Recovery
4 step Now my tablet freezes when cames to "Samsung Logo"
So.... i readed many many pages to be sure of how to install a custom ROM and etcetera... material for 330nu is very insignificant.
Anybody can help me? I'm new in this forum type of thing... i'm a new user in this rooting ways... so I ask for a little help.
Thank u all.

Subscribe to Samsung Tab 4 Discussion group. Lots of info.
Matteo0026 has released a working TWRP.
You probably flashed the faulty version.
Links to working TWRP for T330 Millet WIFI all available and it works. I have T330 and can tell you it works great.
Cheers

make sure you're using the right TWRP recovery, flash the .tar recovery, the TWRP team updated their TWRP to 3.0.0.0 use the latest one and make sure you use it as AP in odin

Why you flashed boot.img on recovery? Of course it doesn't boot. Go to my thread, download my TWRP and flash it in Odin.
