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?

Then it starts installation, but aborts it in a few seconds. So am I booting to just a normal recovery mode and not CWM?

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.

Definitely I need to learn russian lol
Registering in 4pda without any russian comprehension is a hard task
EDIT: WTF? I cant pass by a russian captcha! looooooooooool

====================================================================
1.Go in Twrp do a full wipe(data,cache,dalvik,system)

6.After that, our Full Rom, rename to update
7.In recovery click on adb update(or differently)
===================================================
A few questions to help me clear my confusion ?
4.After flashing it will load you into the Rom = .184 stock rom from raw .184 ?
6.After that, our Full Rom, rename to update and sideload = .184 stock rom
Any particular reason why we would need to sideload stock .184 rom -- when we are in .184 stock before putting FOTA 6.0 to internal ?
is it patched the 2nd .184 ?

@Russiamen did you make modifications in the 'full rom' zip file, or is it the same zip file that we can download from Asus site?
And I have the same doubts that @timbernot 's ones.
There is an newer MM build (V4.21.40.78_20160624_7972). Could I flash it instead the provided FOTA?

do you have a download link for 78?

after this steps the rom will rooted or have to root it?

Thank you for your guide
but raw rom link has not any file for z00a
i found this
https://mega.nz/#!KsAmkYwD!Aci3fETLz0NwdIOqcr1Bf6pAi_MPQkolc15kuM50hAo

Trying to flash raw image didnt worked. Error attached

For Z008-https://yadi.sk/d/Y51bbCIZsVaMf this link not working plz fix this link there showing "nothing found"

The Raw link for Z00A says "nothing found," and the FOTA for the Z00A says it needs a decryption key.

So this guide is to update your bootloader to the marshmallow firmware. So you can install Marshmallow based ROMS?
The reason I'm asking is because i've Unlocked my bootloader and installed the latest version of TWRP 3.02.0 Z00A and I was on android 5.0 on stock ZenUI. I'm getting Error 7 everytime I try to install a ROM. I'm certain i'm installing the correct ROM for the device. I've also wiped the device, cleared the cache, ect. And still nothing. Any suggestions? Thanks for the help.

hello，my zenfone ze551ml might be going to upgrade to mm 6.0， please tell me is it marshmallow stock rom camera better than 5.0？ is it 6.0 have setting sd card become internal storage？ is it 6.0 have mass big storage not just mtp when connected to pc ？

How to unroot and get locked bootloader again

Hi, I rooted my tablet about 2 months ago - Now I have root and TWRP. Now I need to remove root and put a stock image with locked bootloader.
Do you think I can do it by my own? (for example, with fastboot?)
Many thanks

Hi,
You can achieve this by following methods.
Method 1
Since you have TWRP
you can flash the stock firmware from TWRP and it should lock the bootloader, unroot and then overwrite the twrp with stock recovery.
What you need?
For this method you need the stock firmware zip files and firmware finder app from google store.
Method 2 (risky, not recommended)
Download SRK tools by somboons
From here https://forum.xda-developers.com/showpost.php?p=66627615&postcount=2
Unzip the file
Open the application
Then on the main screen, you will have plenty of options to type 1, 2, 3, etc..
Just type 000 to enter the command prompt here.
Once you are in that command prompt you can type the adb commands.
to lock the bootloader you need to type
fastboot oem relock xxxxxxx (just check this command. I think
xxxxx is your bootloader unlock code (yes you have to use the unlock code here again)
this will relock the bootloader.
now to unroot
you can just flash stock firmware using dload method.
How?
download the stock firmware
extract the update.app
put this update.app in a dload folder in sdcard.
you have to create this folder on sdcard and name it as dload.
then you can use the code from dialer pad
*#*#2846579#*#*
from there select SDcard upgrade.
It will reboot and flash the stock firmware. You no longer have root. It will also overwrite the twrp recovery with stock recovery.
I would recommend the method 1. It is safe, easy and should complete the desired tasks within no time.
Method 2 has lot of steps and there is risk involved so I cannot recommend this procedure as confidently as the first one.
I have the Huawei Mediapad M3 LTE version and also Huawei Mate 8. There are few similar functions in Huawei devices.
So now the question is where you will find the stock firmware?
You can find the stock firmwares using firmware finder app in google store.
From here -> https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder&hl=en
Install the app.
Open the app
It will automatically find the right firmware's by detecting your tablet model.
All links might not work
So check the one that is working and download that firmware - preferably full firmware.
You will get the zip files if there are two or just one.
then you can follow the method 1.
Hope this works out for you. Hope you find this information useful. :good::good::good:

Hi and many thanks for your kind response!! I tried as you adviced, the problem is that now i have a custom rom and this is the reason, I suppose, for which, every firmware i try to flash, it says "this version is not compatible with the one installed". For what you know, is there a way to flash the firmware without it to check the one already installed?
Thankssss again!!

Hi,
Can you give me more details about your tablet ? It will be in settings - > about device
like
tablet version - is it BTV-DL09 or BTV-DW09?
DL09 is the LTE version
W - is the wifi version
which OS are you running currently?
TWRP version ?
How did you try to flash ? When method did you follow?
I don't know if there is a way to check what you are asking. But we can certainly resolve your issue.
When I was flashing and experimenting on my Huawei Mate 8 last week I came across similar errors. That time I had to dload rollback package from SDcard and then I flashed the EMUI4.1 OS to get back to stock. Now I feel that is the case with your tablet too.
Process is same for both devices. But the files used to flash are different (naturally). That is why I am confident that we can try to come up with a solution.
Point to note
to flash stock rom, the following play a key role.
1) bootlocker - locked
2) recovery - stock
3) Rollback package ( this was really file for Huawei Mate 8, but is it important for Huawei Mediapad M3? I will try to find out).
At the moment, you have custom OS and custom recovery.
so best thing to do is flash the Stock ROM zip files from TWRP. I explained why it is better to do it this way.
Were you able to get the stock rom zip files?
Also please answer all the questions in this post so that I can help you better. :good::good::good::good::good:

Hi Sama, below in bold my answers.

It's the LTE version, BTV-DL09

Android 6.0, EMUI 4,1, Greatslon mod B030
TWRP version ?
Twrp doesn't start anymore and so did root. This happens since yesterday, after installing the custom rom.
How did you try to flash ? When method did you follow?
I installed firmware finder and tried the following firmwares :
BTV-DL09C233B332, 1273 MB, OTA
BTV-DL09C233B035, 173 MB, OTA
BTV-DL09C233B030, 1801 MB, FULL
and always I get the same response : your firmware version is not compatible - upgrade failed.

I'm not sure that I still have custom recovery, cause I cannot go into it anymore...

ok
so your root doesn't seem to work
you don't know if you have custom recovery
you are using EMUI 4.1
1) do the factor reset from the settings > go to -> Settings -> Advanced settings - > backup & reset - > factory data reset
do this - it should take few minutes
2) then -> developer options - > turn on "oem unlock" and " usb debugging " - on
3) please download the srk tools - I think I gave you the link to that software in my previous posts - > please download - extract keep it ready.
4) open the SRK tools - > type 000 in the place where it asks you to type 1 or 2 or 3 .. - you should get command prompt
5) Now press volume down button and hold .. and then connect your tablet to computer ( you have to enter bootloader mode)
6) now we need to lock the bootloader - so run the adb command ( for this you need to put the tablet in bootloader mode )
fastboot oem relock xxxxxxx or fastboot oem lock xxxxxxx
yes you will need the unlock code and in the above command replace the xxxxxx with your unlock code.
lock your bootloader.
7) it will do factory reset - and then your bootloader is locked.
Now at this point you have bootloader locked and you have normal firmware but since you want to go back to stock rom
I am still not clear about the build number. Can you give me the build number ? its in settings - > about tablet - > mine is BTV-DL09C100B006
Model number you and I have the same version. BTV-DL09. But it is the build number which matters.
I checked the firmware finder - unfortunately it is not giving the full firmware - only ota updates.
so the factory reset in the first step above is very very crucial.
The other safe way to get the firmware is through Hisuite
for this you need Hisuite software - you can either go forward to B009 or if it is giving you that option to switch to earlier version then you can go back. But I highly doubt it will give anything. So just try to go forward with B009 ROM.
try all these steps... see if you can succeed to any extent. In the mean time I will try to search for full firmware and if I do I will update this reply or give a new reply.
My name is Sam Hope this works out for you. Don't worry if this doesn't work then we will think about alternatives. But these are very important steps. Good luck. :good::good::good::good::good:

Update: After going through some of the threads on xda I came across one russian website
http://4pda.ru/forum/index.php?showtopic=780572&st=0#entry54523165
you can check the firmwares. They are all custom firmwares. But I am not sure if the version is compatible. check if your tablet buildnumber is BTV-DL09C100B006 or BTV-DL09C233XXX . that is something you need to be careful.
update2 :- http://hwmt.ru/oth/HWFF/info/view.php
this link contains all stock firmwares - but they are all OTA and not Full package.

I have the US version (I believe it is distinguished as BTV-W09C128Bxxx). Using the firmware finder, it appears the only old firmware available for my build is B001_demo and it's only an OTA. If my goal is restore stock recovery, will downloading this and flashing this do anything? I currently have greatslon's TWRP rooted running stock firmware version BTV-W09C128B002. Thanks!

Btv-w09c128xxx

if you check this Russian site
http://hwmt.ru/oth/HWFF/info/view.php
you will find 8 matches for your model.
unfortunately, all are OTA and not full firmware. OTA is good for updating from lower version to higher version. But for downgrading or returning to stock I am not sure. In my experience, I always used the FULL package.
your current situation
1) you have TWRP
2) Rooted ( so bootloader unlocked)
your options
1) Returning to stock seems to be difficult. Only possible way is Hisuite but it won't recognize your device as your tablet is rooted and bootloader unlocked.
To return to stock
a) you need stock recovery ( you will get this once you flash Stock rom in twrp or through erecovery - download stock rom)
b) bootloader locked (this is possible by adb commands using SRK tools )
c) Stock rom (this is the problem - I couldn't find a single site which is hosting FULL stock rom )
d) rollback package ( If there is one, Huawei had it for Huawei mate 8 but for mediapad m3, does it have? I don't know) - I hope this is not mandatory. We should be able to get the job done using a,b,c . previous points.
From my experience, I found that if you have a, b, c you can go back to stock easily.
I saw another Russian site where they have custom roms. But you have to be careful. Check if the version they put out is compatible with yours. You mentioned that your tablet version is BTV-W09C128Bxxx. It looks they have custom roms for BTV-W09C233xxx Can you flash this firmware on your tablet? that is tricky and can be risky too. If any one has done it, then it would be nice if they can share their experience.

The OTA in the firmware finder is not enough to go back to stock. You can try but I am not hopeful because it is not complete firmware and it might get stuck in between or fail.
For now. you can do factory reset from TWRP. That is the only thing that seems possible. Without stock rom or rollback package, it is very difficult to go back to stock. But if you manage to get stock rom for your device. Then flash it in TWRP. Once it completes you will have stock rom installed on your device.
Hope you find this information useful :good::good::good::good:

Thanks for the reply and the useful information. It seems as though I'm out of luck unless I can find a FULL stock firmware package. However, you did mention that I can use Hisuite? Even though I am unlocked, TWRPed, and rooted, Hisuite still does recognize my device (I think it's because I'm on stock rom). When I click on System Recovery it just says "Your device system is running properly and does not need to be recovered." Is there another method I can go through using Hisuite to restore stock recovery?

That's great news.
Good that your tablet was recognized by Hisuite.
For system recovery to work. You have to press volume down and then connect the tablet.
Did you do it this way? I think you did.
Do you have "update" or "restore" option in Hisuite?
If yes when you click on "update" did you get "switch to earlier version" If it gives that then yes you can try but even then we have to keep fingers crossed until it completes the process successfully.
One more thing you can try is using HiCare. But this is for updating to nougat or for OS early adopters.
All the options are coming down to stock rom. If you have one stock rom. Then you can flash it in TWRP or extract the update.app and dload it using 3 finger rule.
Full stock rom - that is the key here. Is it possible for you to get the stock rom for your device? So far I found only OTA's from those Russian sites or custom roms for different models. It will be great if can find all stock firmware's for all the models. It will help many people. Since my tablet was working very well, I didn't think about rooting at all. Mine is BTV-DL09C100B006.
One last option is Unroot your tablet using Supersu app. And then flash boot.img (it is recovery.img not boot.img) from one of the OTA firmwares. that way you can get back to stock firmware. But this is tricky. You have to be very careful about this. If anything goes wrong here then you won't be able to boot into tablet. That is why I cannot recommend this option.
Sorry I made a mistake in this post. It is recovery.img not boot.img. Please be aware.
You can try - Factory reset - from inside the OS or from TWRP. :good::good::good::good:

1) When you say pressing volume down and connecting the tablet, I'm not quite sure what you mean. Do you mean from power off? Anyways, from a power on state, I tried using the Update process within Hisuite and it downloads the B003 firmware, then boots into recovery (TWRP), attempts to flash it, fails, and then I manually have to hit restart system within TWRP.
2) I downloaded an OTA update.zip and could not find a boot.img.
3) Also, what does factory reset from inside the OS or from TWRP do exactly?
Thanks again!

I am sorry. I should have explained it better.
Pressing volume down and holding it for few seconds and then connecting to computer will take you to bootloader mode.
Then you can do the system recovery.
Yes, if you have stock recovery it will go smoothly. You have BTV-W09C128B002. So you need boot.img of the stock firmware belonging to this OS. then you have to flash that using the below adb command
fastboot flash recovery recovery.img
this should get back the stock recovery. Once you have this. You can try the Hisuite again, this time hopefully it should complete the process.
- you have the update.zip - > extract the update.app -> use Huawei update extractor (software in the attachment) -> extract this zip - > run Huawei UpdateExtractor - now open the update.app - > you will be able to see the recovery.img extract it. Flash it using the adb command in SRK tools.
you can download SRK tool from here -> https://forum.xda-developers.com/showpost.php?p=66627615&postcount=2
Open this tool - > type 000 where it is giving you an option to type 1, 2, or 3 etc.. you will get command prompt . there you have to type the fastboot command to flash the boot.img.
But once again. Just want you to know this process is risky. Wrong file or if anything goes wrong you won't be able to boot into your device. So please be careful. It is risky. Please do not proceed with these steps. Flashing the stock rom is the right way. Or Hisuite. Those are safe methods. But not this.
Factory reset from inside the OS means - > go to settings - > advanced systems -> backup & reset -> factory data reset
that will do the factory reset on your device.
or
since you have TWRP. you can boot into TWRP - go to wipe - > there you will have factory reset. you can do it that way too.
I apologize for not explaining properly. I am sorry I made a mistake. It is recovery.img not boot.img.
Hope you found this information useful. :good::good::good::good::good:

Hi Sam!
unfortunately the custom rom I put 2 days ago hiddens the build numer (it says "B030 greatslon mod") but I annotated the previous one, which was the one you said "BTV-DL09C100B006".
Now I'm at work but this evening I'll try to do what you adviced. Thanks again and have a good day

Yes, I continue to find your information very useful!
I have downloaded the Huawei Extractor and was able to use it to extract boot.img, fastboot.img, and recovery.img. However, this is for B003 and I am currently on B002. B002 does not appear to be available through the links you previously provided (neither OTA nor Full). Using B003 extracted files, what would be the proper sequence of flashing? Should I install the B003 boot.img first, hope that it boots into fastboot, and then flash B003 recovery.img in fastboot mode? How do I even go about installing B003 boot.img? Through SRK tools or adb? Or is this all too risky, and I should not even bother with B003 OTA files while I am still on B002?
Thanks again!

Hi Sam!!
I recovered my huawei unlock code and tried to relock the tablet, after having resetted it to factory (remember I still have custom rom).
After putting the tablet in bootloader mode and typing the following command on sk tools:
fastboot oem relock xxxxxxxxxxxxxxxxx (my unlock code)
I get:
....
FAILED (remote: stat not match)
finished. total time: 0.00 secs
I also tried "fastboot oem lock xxxxx" but it says "command not allowed".
Do you have ideas? I am blocked there...
Thanks!!

Hi,
You can achieve this by following methods.
Method 1
Since you have TWRP
you can flash the stock firmware from TWRP and it should lock the bootloader, unroot and then overwrite the twrp with stock recovery.
What you need?
For this method you need the stock firmware zip files and firmware finder app from google store.
Method 2 (risky, not recommended)
Download SRK tools by somboons
From here https://forum.xda-developers.com/showpost.php?p=66627615&postcount=2
Unzip the file
Open the application
Then on the main screen, you will have plenty of options to type 1, 2, 3, etc..
Just type 000 to enter the command prompt here.
Once you are in that command prompt you can type the adb commands.
to lock the bootloader you need to type
fastboot oem relock xxxxxxx (just check this command. I think
xxxxx is your bootloader unlock code (yes you have to use the unlock code here again)
this will relock the bootloader.
now to unroot
you can just flash stock firmware using dload method.
How?
download the stock firmware
extract the update.app
put this update.app in a dload folder in sdcard.
you have to create this folder on sdcard and name it as dload.
then you can use the code from dialer pad
*#*#2846579#*#*
from there select SDcard upgrade.
It will reboot and flash the stock firmware. You no longer have root. It will also overwrite the twrp recovery with stock recovery.
I would recommend the method 1. It is safe, easy and should complete the desired tasks within no time.
Method 2 has lot of steps and there is risk involved so I cannot recommend this procedure as confidently as the first one.
I have the Huawei Mediapad M3 LTE version and also Huawei Mate 8. There are few similar functions in Huawei devices.
So now the question is where you will find the stock firmware?
You can find the stock firmwares using firmware finder app in google store.
From here -> https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder&hl=en
Install the app.
Open the app
It will automatically find the right firmware's by detecting your tablet model.
All links might not work
So check the one that is working and download that firmware - preferably full firmware.
You will get the zip files if there are two or just one.
then you can follow the method 1.
Hope this works out for you. Hope you find this information useful. :good::good::good:

Yes it is very risky. Please proceed with caution or don't do it at all as these steps are risky and can turn your tablet into brick. I say this because we are not getting the right set of files to test properly. We don't have the rollback package or stock ROM so the situation is precarious. If anything goes wrong, it would only increase your problems. For going back to Stock all you need is Stock Recovery & Stock ROM and unroot.
You are in stock rom but rooted. You just need to flash the right recovery.img file using SRK tools. Please check my previous posts on how to run adb commands using SRK tools. You have to do this in bootloader mode. Fastboot or bootloader mode are one the same. You need only recovery.img and that should be flashed in fastboot or bootloader mode. Check the Russian site http://hwmt.ru/oth/HWFF/info/view.php this has B003 firmware
For the moment it appears like there is only one way forward if nothing else work for you. I hope you have seen the Greatslon ROM files in the other threads. You can download his EMUI 5.0 it looks gr8 and seems to be stable from what I read. He has uploaded all the required files for his ROM. Have a look and see if it interests you.

You and I have same tablet version. I bought my tablet on Amazon.de. Please make a note of your steps and how your tablet responded. Based on that we can see how to move forward. It will be really helpful to know your experience.
To both of you @danibyte27 and @asianpianoman
Please be careful while handling these .img files or any system files. Flashing wrong files or any mistakes or errors during flashing can be detrimental for your tablets. There is huge amount of risk. So please proceed with extreme caution. Do not proceed if you have doubts. Please do not hesitate to ask if you are in doubt.
It appears that Greatslon - Android Nougat ROM seems to be the best way forward. As you have seen FULL Rom is not available anywhere. So that complicates things. Going back to stock ROM seems to be very tricky for now until we get the right Stock ROM and other important files.

Did you put the oem unlocking - ON & usb debugging on ?
1) check the bootloader - take a photo and see if it is showing phone locked or unlocked
hold volume down on your tablet for 3 seconds and then connect to computer
update : Can you check if your unlock code is correct?. it says "stat not matched" please check the unlock code.
risky steps
[[[try fastboot oem unlock xxxxxxx even if it says your phone is unlocked. ]]]
[[[then fastboot oem relock xxxxxxxx]]]
if this doesn't work
then flash the recovery of your current firmware using
use SRK tools - go to command prompt - type the below command ( this recovery.img should be in SRK folder )
fastboot flash recovery recovery.img
I would suggest you not to go back to stock. Please try to move forward to greatslon EMUI 5.0 ROM.
https://forum.xda-developers.com/mediapad-m3/development/twrp-greatslon-mod-t3489232
Please check this link https://androidfilehost.com/?w=files&flid=125388 he has uploaded all the files.

It appears he didn't upload the EMUI 5 ROM for BTV-DL09C100 in that link.
However, he uploaded EMUI 5.0 on this Russian forum
http://4pda.ru/forum/index.php?showtopic=780572
But those seem to be for C233 and other versions.
So I think it is better to check with him on the other thread https://forum.xda-developers.com/mediapad-m3/development/twrp-greatslon-mod-t3489232 and see if it is ok to install C233 on C100. It is his work so I feel he is in best position to answer this question . :good::good::good::good::good:

Good news!!! Stock ROM link

Hi,
Hope you remember me.
Finally I have some good news for you.
Some wonderful person found the link to download the Stock ROM & Rollback package in another thread.
here is the link
http://consumer.huawei.com/it/support/search/index.htm?keywords=btv-dl09&t=SupportSearch
Go to this link and download the Rollback package and then do the dload method. You will come back to Stock ROM and your bootloader will be locked again. Download both files. Site is in Italian, you can translate it to English. This is the file I was talking about in my previous posts. It was uploaded by Huawei only on March 30th.
This is straight from Huawei so no risk at all and very safe.
They also have the B009 firmware so you can use dload method again and update it to that firmware. After that you can do whatever you want
I hope this is useful for you.
Cheers!
Sam :good::good:

I am glad you found it useful. Please have a look at all my posts in other threads as well. I have explained the steps in detail.
There is Android nougat available too. B006 -> B009 -> B010 - > B301 - > this is the path you need to take to get to nougat if your tablet model is C100BXXX. And all these firmwares starting from B010 are available on firmware finder app.

Hey guys,
I installed MIUI 8.2.5.0. But I want to roll back to 8.1.. How likely am I to brick my phone without performing all data wipe? My BL is locked and since the PC suite is not working I can't get to recovery without unlocking the device and I don't want to do that.

Use Mi flash tool. Download the fastboot ROM of your device and the version you want to roll back. Install all the device drivers. In flash tool, select all except storage of the tool detects your device, flash it.

So flashing it from Updater in settings using a zip file is not a good idea?
Thanks for your help anyway.

1. Backup your data
2. Download the miui 8.1.1.0 from here - http://bigota.d.miui.com/V8.1.1.0.MALMIDI/miui_HM3SGlobal_V8.1.1.0.MALMIDI_874f56cdc1_6.0.zip
3. Flash it via updater app.
4. Factory reset your phone.
5. Enjoy
I used the same method and I'm very happy with miui 8.1.1.0

Thanks, that's all I wanted to hear. Running 8.1. again and it didn't even brick my phone ?

Can you please help me?
1) What do you mean by "Flash it via updater app"?
[When I try the "Updater" App, in the menu I choose "Choose updater package", choose the ROM from your link, click "OK" then I get "Can't verify update - Sorry, flash older version is not allowed" after maybe a minute]
2) do you have a link for the last ROM before 8.5.3.0?
Best Regards

Here is indonesian forum. But you can download older rom from it. Scroll until you see this section

Yes.

Sooooo I have a slight problem.
I have TWRP and stock ROM. Sort of. Xtreme Addiction ROM, only one that would work and not give the error"This is an s2 not s2_na_Xxxx" so I Flashed that, and uninstalled root, now in TWRP it doesn't show my internal storage so I can't flash this ROM, and ask for a password. So I tried using the 3dot option from settings and it won't work either, it'll just boot to TWRP and nothing happens. I'm really not looking forward to deleting everything... AGAIN but I will if I have to.

Is there an update for the Le s3 x522 that can be installed though the phone update app? I am still running stock recovery and don't want to change it but it seems the OTA updates not working

I think we might be having the same problem...
My X527 came with 16s as the stock ROM.
Upgraded to 19s with TWRP which gives me the system update option as well as OTA (which says I'm running the latest version).
I want to update to 21s and use the system update method..
Phone starts to load the new update (renamed to "update.zip") progress bar at the bottom of the screen while all of this takes place.
Phone reboots into password screen for TWRP, swipe to continue, then select system reboot and once it's back up and running it is still on 19s...?
Did you get your update resolved?

I did, I used this website. https://www.google.com/amp/s/forum....factory-image-5-8-020s-directly-t3527790/amp/
Downloaded Chinese TWRP from there. As well as that ROM, if you have the 21s update file, I'm sure you can get it working with that TWRP. Hopefully it works for you.

What worked for me was replacing TWRP with the factory recovery and I'm good to go.
There was talk of an official update (beyond 21s) in December but so for, no sign of that...

Interesting, replacing stock Recovery didn't work for me when I did it, and yeah. It's most likely not coming soon due to financial issues LeEco has.

I note that this says it's the ROM for the S3.
I'm using the X527 which is the S2 with the Snapdragon chip (now listed as X526 after installing 21s), did you perhaps flash the incorrect ROM?
I had continual problems upgrading from 19s with TWRP - it would go through the whole process and then reboot to 19s..
Even after the replacement of the stock recovery, the first ROM I downloaded (21s) was not accepted. Had to download another one for it to finally work.
Could be a bad download?

Contact
How did you contact leeco and get this. I need all future updates. My phone is rooted and I am unable to completely unroot it and get OTAs.

If you don't have TWRP or anything installed, it should work fine if you put the 20s update in the root folder (the folder with the android and download folders). Then just go to system update, press menu, press local update, go through prompts and it should update automatically. Then just repeat the process for the 21s update. If you have twrp installed, I'm pretty sure the chinese ydss version doesn't allow OTA installs. This update requires stock recovery installed because it updates through the recovery. You can find stock recovery images on google (search le s3 stock recovery and click skyneel) or, someone might have posted a recovery image on the le 2 forum. Plz reply if it doesn't work, it worked for me tho.

Is there any bugs? If yes please list. Thank you

does it work for le s3 X626 mtk?
if not, please guide me as I see that this forum support Le S3.
thanks.
