Now, We Will Unlock The Bootloader,
Why to Unlock Bootloader?
1.) You can flash custom ROMs/Kernels
2.) You don't need to worry if the new firmware can be rooted or not as with unlocked bootloader u can always ROOT Your device
[ Before We Begin Unlocking Bootloader ]

Make Sure The Fastboot Drivers Are Installed.
Make sure u have a windows PC with USB cable to connect the phone
Power down ur phone and keeping the Volume Up button pressed connect the USB cable to PC this will trigger FASTBOOT mode and windows
Will start driver installation, extract the above package and point the driver install to that location (usb_driver) folder
Once drivers are installed just disconnect cable and power on device.
[ How to Unlock ] (Official Way)
Video Link ---> http://www.youtube.com/watch?v=LRH3pC7MhEA
For better understanding, I highly recommend you to watch the above video along with the instructions below:
1.) Download ‘Fastboot Drivers And Pacakges File For Xperia S’ file from → Here
2.) Extract the file you downloaded above on your PC. You’ll get the following three files:
drivers.zip
fastboot_with_Android_USB_file.zip
3.) Go to: http://unlockbootloader.sonymobile.com/ and read everything!
This will open a web page in your default browser. Scroll to the bottom of the Instructions on the page and you’ll see a link like “Continue”, click on it.
In the pop-up window click “Yes, I’m sure” and then in the next window click on both the checkboxes, and then click “I accept”.
4.) Now insert the details as per the instructions:
First 14 digits of your IMEI No. Do NOT enter the last digit (15th) in the box. To know your IMEI No. dial *#06# on your Xperia Arc.
Your Name
Your Email Address
Click Submit.
5.) You’ll get a KEY to unlock boot loader. Write it down somewhere you can remember, it will be used later.
6.) Switch off your phone.
7.) Now extract the “fastboot_with_Android_USB_file.zip” file you got in Step 2.2.
8.) Pick up your phone (it must be switched off) and hold the “Menu” button (the key at the bottom right of your phone), now while holding the “Menu” button connect your phone to your PC with an USB cable.
9.) Once connected — the LED light near the phone’s USB plug will turn blue. If it doesn’t — repeat the Step 8.
10.) Now to install the drivers do the following:
Extract the “drivers.zip” file you got in Step 2.1
Open “Device Manager” on your PC and look for “S1Boot Fastboot” under the head “Other devices”
Right-click on “S1Boot Fastboot” and select “Update Driver Software…”
Now select “Browse my computer for driver software” and select the folder where you’ve extracted all the three files you got in Step 2. Once done — click Ok.
Now click Next (Make sure you’ve ticked the “Include subfolders” checkbox).
If you see any Windows security warning box, don’t worry . Just select “Install this driver software anyway”
Wait for “Windows has successfully updated your driver software” message to appear on your screen. Now click Close.
11.) Open the “fastboot” folder from the file we extracted in Step 7.
12.) Now hold Shift and press mouse right click (Shift + Mouse Right Click) anywhere on the empty white space inside the “fastboot” folder. And then select “Open command window here” from the context menu.
13.) Now in the command prompt window type/paste the following:
fastboot.exe -i 0x0fce getvar version​
14.) It should return a value like “0.3”. This ensures that your device is correctly connected.
15.) Now type/paste the following line in the command prompt window:
fastboot.exe -i 0x0fce oem unlock 0xKEY​
IMPORTANT! Replace the word “KEY” from the above line with the KEY that you received in Step 5. Then Hit Enter.
Click to expand...
Click to collapse
16.) Now wait for the process to complete. Command prompt will show a “Finished” message when it will be completed.
17.)Once it’s done, disconnect the USB cable from your phone and switch it ON.
18.)Your phone’s boot loader should now be Unlocked.

Troubleshooting
If you experience a bootloop (phone constantly reboots and reboots on the boot screen) or a soft brick (powering on the phone shows an orange triangle with a phone and computer), don’t be afraid. XDA to the rescue!
For a bootloop:
Take out the battery.
Wait for 3 min.
Put the battery in. Do NOT power on the phone.
Keep pressing Volume Up + Home simultaneously and press the power button to turn on the device.
Once the phone shows the model number screen, leave the buttons.
Your phone will boot into recovery.
Select “Wipe data/ Factory reset”. (Volume Up for going up and Volume down to go down)
After the reset is done, select “Reboot system now”.
The phone will reboot and you should be all fine.
For a soft brick:
You probably flashed some faulty firmware or firmware not meant for your device.
The File You Downloaded Must Be Incomplete.
Download the correct firmware and flash again.

woa! really great thread!
thnx for this step by step tutorial.. this really will help me and other begginers here in xperia forum..

there's some mistake in your guide:
first, you can't root last xperia s rom version with Bin4ry root tool
it would be better to link the main thread which then will lead people to the right place
then, i think that instead of using recoverX to install CWM, it would be better to flash advanced stock kernel (and then TWRP if you like)
and you don't need to flash FXP kernel before flashing rom
last but not least... i think that this thread would be better sitting in general section (instead of the android development one)

Thank You! I'd do the same..
And about the Last .55 Version I'd update the thread.
Next for the Advanced kernal.. Its true! but for beginners understanding CWM forms a very good base.
There were some issues with TWRP while providing null value in moving from CM10 to OPEN SEMC
So prefered CWM

Hi, I searched a lot for the way to flash a custom rom on my Xperia S. But now halfway through, I've got a problem. My device says it does not allow to unlock bootloader, so does that mean that there is no way I can flash a custom rom on my phone? :crying:

You cannot flash .zip files using flashtool. You can flash only Firmwares or kernel files using flashtool.

Which recovery are You using? The 2.8.1.0? It doesn't work with Xperia S. Use the 2.8.0.1 version.

Wait i will let you know the complete story.
so what happened is
first i was on CM11 for few mnths then switched to MIUIv5 for 1 month. everything was working fine
but when day before yesterday i flashed PA rom i am not able to access the recovery now (previously there was TWRP in my XS). now i can't flash any zip file
when i reboot to recovery it gets stuck on black blank screen. Even the recovery apps like twrp are not working. when i tried to install recovery through app, the app crashes.
As recovery is not working i cant even switch to other roms or any zip file.
i am totally stuck on this ROM
i asked this que on sony mobile group on FB (created by some sony fans), one of the member said "probably this is not ROM fault but the kernel fault. consider trying new kernel"

Ah yes, even that one doesn't have recovery.
Unlocked bootloader is must.
You need an Android app. You can find the app here. Also, here is the page of the twrp.
What You need to do is, download the twrp from here. Rename it to fotakernel.img .
Then copy it to Your sdcard.
Then run the following commands on the terminal emulator app:
Code:
su

[GUIDE] HOW to FLASH latest WW/CN/TW | ROOT | UNBRICK |

I. Before You Begin Doing Anything
**As with all of these types of tutorials, this may void the warranty of your device. Do it at your own risk.
**Download and install the Asus USB Drivers on your PC, if you haven’t done so yet.
**This should only work on a Windows based PC only.
II. Downloading Required Files
** Necessary tools and Drivers - Mediafire Folder
**Latest OTA form ASUS website : WW_2.17.40.12
** Boot.img, Droidboot.img and Recovery.img from this MEGA Drive posted by Chinaphonearena user and belong to Shakalaca.
** System.img - if you want your phone ROOTed on latest ASUS ZF2 Firmware.
III. Yeah! Im ready to do it
**Plug in your device to your PC using a USB cable.
**Boot your device to fastboot mode Power + Vol Up to enter Bootloader Mode
**Hold down Shift and Right-Click anywhere in Fastboot Folder on your PC and select Open command here. It will launch a Command Prompt Window for you to issue commands to your device.
**When it launches, type in the following command and press Enter (.img files has to be in same folder as fastboot tools):
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash fastboot droidboot.img - droidboot.img is fastboot, and if you somehow will flash corrupted image, you won't be able to boot to fastboot anymore. Thanks to sorg
fastboot flash system system.img - Only if you use Pre-ROOTed system image from MEGA Drive.
IV. Ready to go with OTA!
** Upload WW_2.17.40.12 or latest Firmware OTA ( Full firmware ) file to phone storage (Phone storage/File.zip)
** After uploading .zip OTA file to phone storage, unplug USB cable from phone. You will recieve notification that new OTA UPDATE is avaliable for installation.
When you bought CN version of ZF2 you may have to Rename OTA file from UL-Z00A-WW-2.17.40.12-user.zip to UL-Z00A-CN-2.17.40.12-user.zip to get notification about update avaliable.
** Wait till update will finish (approx 10 - 15 min) . Phone will restart when finished. First boot may take longer.
V. Dam! No Notification!? what now...
** Boot your device to fastboot mode Power + Vol Up to enter Bootloader Mode
** At Bootloader press Vol Up to choose Recovery Mode
** You will see an error message of updating ota. Wait 5 sec and then press Power + Vol Up simultaneously until you see recovery menu.
** Using Vol Down + Vol Up choose ADB mode and connect your phone to PC via USB cable

Are you sure this works i mean there are thousands of threads regarding this issue but none of them work..Can someone with CN version confirm the working of this method....

I bought phone on Aliexpress website. Phone has WW OTA but update via Wi-Fi was impossible. Firmware was 13.40.13 so i think people with that firmware had CN version at start, then sellers updated it to 13.40.13 WW and sended to buyers. Following my method you can update to the latest WW.

Works fine. We've published a similar method. I recommend using the latest rooted ROM. Note, your LTE 4G bands won't be changed with this method.
Have written out the steps in detail for novice users. Includes setting up adb etc: http://www.chinaphonearena.com/forum/showthread.php?tid=10253

I agree.
But your method is only for pre-rooted system.img with 2.13.40.13 firmware.
I posted method for full OTA firmware upgrade.
Yes, it is similar )

The method posted can be done with any system.img (don't have to use rooted ROM), there's no need to do the OTA update as its already the latest ROM (though it will be compatible with future OTA updates, thanks to the ROM creator), and you end up rooted.
They are essentially the same, except for flashing system.img at fastboot instead of doing OTA update. Take your pick. If not caring about root, your method is certainly quicker, as there's no need to DL the huge system.img file.

Thanks. Much appreciated

confirmed works fine on a rooted CN version
Hi,
I followed all the steps and apart from thinking I'd bricked it (the system update screen was sat with the blue bar unmoved for 15 minutes) . It's just completed perfectly.
Really great advice - thanks - I got 2 of these handsets yesterday via ebay both came rooted and it turns out they are CN models but had WW software on them - as per your model - prior to reading your post I was probably going to try and send them back.
I hope and presume for future updates I can continue to use this method?
will do 2nd one now.
Cheers
Ian

Thanksssssssssssssssssssss
Honestly, last time that I tried to have a custom ROM or in any other words, last time I installed and used ( I'm still using it) it was on my samsung galaxy tab(the first galaxy tab of all time) two years ago!
At first I was puzzled in all of these forum pages. I started to change my CN rom to WW Rom yesterday at 2 o'clock. Since I started this process, I just ate dinner and slept for 5 hours. The rest of the time I was trying to install 7 different roms which are available in this forum or asus zenfone forum by 3 different methods of loading a ROM! NONE OF THEM WORKED CORRECT AND COMPLETELY. so I had to start again and read. I can easily say that I've read more than a fat ass book for this process (most of them were duplicates, but I was looking for s.th new among them...)
Your method worked just nolw (@ 1 pm) and I'm really thankful. Honestly I was so bumped and I was thinking to send this device back, just an hour ago I saw your way for the second time and I just decided to try this time as the last way, before returning it!! thank u again for giving me a zenfone
keep up the good work

Confirmed ok on 2nd handset - red CN model 32gb 4gb ram.
It has removed the root access though... Supersu app has gone. and Root checker confirms not rooted.
Which is ok because I can now use Skygo app on the phone - really wasn't expecting that to work!

Thanks guys for good news that it work for you too. I hope that TUT will help others to get rid of 13.40.13 which drain battery as $%^&. Without root it's hard for efficient battery save but atm i use battery doctor from G market and I need to say after 4h it drained 3% battery with turned WiFi. I just wait for proper root tutorial.

Several proper root tutorials already posted. Just follow your own tutorial but flash the pre-rooted system.img. Bam, done.

But latest system.img is not from newest bug fixed firmware mate. That's the problem.

Hello,
Im stuck at no.5, sorry to ask but I don't know what you mean by phone root storage and where it is found.
Can you help please

He means the base of your SD card. Don't copy the OTA into a folder on SD. Copy it to the base of the SD.

with my cable still connected and fastboot still open?
Because I have put it in the sd card nothing happen

Reboot the phone. You should get an OTA update notification. Or boot into recovery and apply the update from there.

This is my version of the steps:

As far as steps, I can only speak of the ZE551ML. Start with an unrooted OS.
1.) Download the ADB and Fastboot tools from google (see links above). Download the pre-rooted from from shakalaca in post #1 (If you download the 200MB split version, Windows File Explorer will allow you to open the .zip and copy the .img file out.)
2.) Download the stock full ROM WW_2.15.40.10 directly from support.asus.com
3.) Plug the phone into the PC via USB and copy the UL-Z00A-WW-2.15.40.10-user.zip onto the phone.
4.) The phone will notify you that there is an update:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
5.) When you select the notification you will be prompted of which file to use in the update:
6.) Hit OK and the phone will reboot and update everything it needs to update per ASUS. (This will include the fastboot/droidboot image, boot, recovery, system, silentlake, and modem firmware.)
7.) Once the update has completed, unplug and power off the phone.
8.) While holding volume up, press the power button until the phone vibrates. At this point release the power button but keep holding the volume up button until the screen flickers to the fastboot menu. Release the volume button when the screen flickers.
9.) Plug the phone back into your computer, open a command prompt and navigate to where you extracted the google tools and the system.img.
10.) Run:
fastboot devices
11.) You should see a your device listed, if you do not, your device is not in fastboot mode.
12.) Assuming you see your device listed in Step 10, run:
fastboot flash system system.img
This will erase your current system partition and then start writting the new image to the partition. Fastboot will split the system.img file into ruffly 500MB chucks and send them to your device.
13.) Once its finished, you can select boot normally on your phone by pressing the power button or run:
fastboot reboot[/QUOTE]

This is a guide for XPERIA ACRO S (other xperia users can also reffer needed information)
[Below procedure looks lendy, but you'll just need max 30 minutes if you have every downloaded file.]
I make this guide for noobs as there weren't such guide (even for my first time of flashing ROM I didn't get any such guide, so I decided to make one)
This Guide is especially for flashing BPaul's 5.1.1 ROM
So here Iam giving detail process to install Bpauls 5.1.1 with every links needed.
we are going to take below steps;
1. unlocking bootloader
2. flashing kernel with recoveries
3. backing up stock rom
4. installing bpauls 5.1.1
Special Thanks;
@BPaul (for awesome ROM)
@cobrato (for stock kernel)
@jajb (for gapps)
NOTE: I'AM NOT RESPONSIBLE IF YOU DAMAGED YOUR PHONE BY CROSS FLASHING OTHER ROMS,KERNELS ETC.
BELOW PROCESS IS SUCCESSFULLY CARRIED ON XPERIA ACRO S. AS NOOBS CAN MAKE MANY MISTAKES
I'AM NOT RESPONSIBLE FOR YOUR DAMAGE. -DO AT YOUR OWN RISK-
-Here we START-
*_UNLOCKING BOOTLOADER_*
(unlocking bootloader will erase everything on your phone, i suggest you to take backup of your data)

Explain the unique and wonderful brother, thank you
But there is a point I can't understand, come on for
Install the kernel
Put a link to the kernel and you try to access the file to download
They found three links and no! know which is better or more correct for installation
Thank you for all your explanations about the wonderful but if it is possible to make a video for us to install the ROM I was very thankful to you
A point I would like to inquire of the installation steps that I have created on installation after the formal system of the machine or from another custom
And you have to work the manure and how it works
I hope I haven't she disturbed you thanks
Wait for response from you, since I'm a wait to install this ROM
Great job thank you

[GUIDE] Rooting Teclast X16Plus (for both Remix OS 2.0 and Default Android 5.1)

(I wrote the 'new' version of rooting out of memory / conjecture, it should not do irreversible harm to your tablet, however, always apply common sense and proceed with caution. Caveat - I am neither a developer nor software engineer.)
'New' version of rooting procedures can be carried out with relative ease now that @krustymars has done the heavy lifting and ported TWRP to Teclast X16Plus; applies to both native android 5.1.1 and Remix 2.0.
In his write-up, it wasn't mentioned that TWRP can only be installed if X16 Plus's bootloader is 'OEM unlocked' and ROM will only boot if X16 Plus's boot image is patched (insecured), after the flashing of TWRP.
To unlock is not difficult (fastboot oem unlock), but it will also wipe /data of the ROM (making it unbootable too?). Question mark here as I am uncertain whether this action will render the ROM unbootable or not. For the sake of not doing double jobs, we assume it will.
The third condition for the ROM to first boot properly after flashing is the original recovery must be present (again I am not sure if a patched boot image will do the trick; for the same reason above, we assume it won't)
Therefore the only way out is to ensure the bootloader is not re-locked after the flashing of ROM, for us to be able to flash an effective TWRP AFTER the ROM has finished its first boot.
I believe the above are the main reasons why @stratos7 faced difficulties when intending to root via TWRP.
A simple and rudimentary step by step guide as below (you will LOSE ALL DATA in the tablet, backup all your important stuffs before proceeding):
1) Rename the ROM's original recovery.img to recovery.org. Copy krustymars' TWRP over and rename it recovery.img
This is to ensure that after the flashing, the reboot process will fail and the script will not re-lock the bootloader
2) Flash the ROM as per normal (enter DNX Fastboot by pressing vol+ vol- and power button concurrently, then use Intel Platform Flash Tool Program to flash).
3) After a successful flash, the tablet will enter recovery (TWRP) first time during reboot, and failed. It will be stuck in a boot loop (showing TWRP error).
4) Force shut it by pressing the power button for 10-15secs.
5) Enter fastboot by pressing vol- and power button concurrently.
6) Flash the orginal recovery via adb fastboot.
fastboot flash recovery recovery.img
7) Reboot normally and the ROM will load properly (1st successful boot will take a while; as long as you see the Remix OS logo flashing, all are good).
8) 10x click on Build Number to activate Developer's Menu
9) Activate USB debugging
10) Reboot into fastboot by typing
adb reboot fastboot
11) Check to ensure that bootloader is still unlocked.
12) Flash krustymars' TWRP
fastboot flash recovery TWRP_TeclastX16Plus_by_krustymars.img
13) Flash patched boot image
fastboot flash boot boot.img
14) Choose Recovery Mode, ensure X16 Plus boots into TWRP fine
15) Reboot into ROM from TWRP
16) If you are satisfied that all are fine after rebooting into the ROM, and have copied the latest downloaded SuperSU.zip flashable file into the Internal or Micro SD memory, you can either adb reboot fastboot or shutdown the tablet and vol- power button into fastboot, and then choose Recovery Mode from within fastboot to enter TWRP to flash SuperSU to get root.
Do note that you cannot update binaries within Android, you can update the SuperSU app though if a new version comes up in Play store, just not the binaries. If your binaries become outdated, you will need to flash the latest SuperSU.zip again via TWRP.
The necessary files (minus SuperSU, do grab that from Chainfire's site) - https://www.mediafire.com/?3blso8sjw4kb3e6
Once again, proceed with caution / common sense and the above shouldn't land you in any irreversible situation. All the best!

OLD METHOD
The below instructions for rooting Teclast X16 Plus originated from Teclast's forums. All credits go to the respective creator(s), I merely translated them to post here.
1) Download the standard rooting package from http://www.mediafire.com/download/nrez4ggzau1u8ax/Root.X16Plus.V1.zip
2) Download your corresponding edited boot image file and extracted build prop file (for either Remix OS 2.0 ver B2016062701 or Android 5.1 ver 1.07)
- for Remix OS http://www.mediafire.com/download/b6aazky2y9eqch7/Remix_OS_2.0.zip
- for Android 5.1 http://www.mediafire.com/download/zz40a8cgav385l3/android5.1.zip
3) Download and install Intel's tools and drivers in the order below - http://www.mediafire.com/download/p723or9hxip5eu8/Intel_Flash_Tools.rar
You can omit this step if these drivers are already installed.
- iSocUSB-Driver-Setup-1.2.0.exe
- IntelAndroidDrvSetup1.10.0.zip
- PhoneFlashToolLite_5.5.2.0_win32.exe
4) Download kingroot tool from below, copy the apk file to your X16 Plus and install. There is no need to run the installed app now.
5) Ensure USB debugging is switched on under developer options in your ROM
6) Unzip both the rooting package and your corresponding edited boot image and extracted build.prop files. Cut and paste the unzipped boot image and build prop files into the unzipped rooting package directory.
7) Launch command prompt and change directory to the unzipped rooting package directory

Hi @potatohead , Hi @TrYkeR ,
I've just discovered a new firmware V1.07 for our X16 plus on the Teclast website (in the download section) . My tablet is running with the V1.04 version.
Do you know you to flash it, cause TeclastOTA is unable to ugrade it both with the Online mode ("undiscover new version") and the Local mode ?
Reno.

I'm using 1.07, I use a tutorial from their webside.
The big problem is download the firmware, their server sucks a lot. I use jdownload since chrome crash 2 times and do not recover the download
Firmware:

here they talk about it:
http://techtablets.com/forum/topic/teclast-x16-plus-i-want-to-change-from-v-1-04-to-v-1-07/
I didn't find the post that I use, but was really easy, like paste the .img files into a folder, put teclast plus in "download mode", they called it diferent, and run an script (.bat)

Hi @TrYkeR,
Thanks for your prompt reply.
I searched for the tuto but I didn't find it too (I already have the V1.07 download). I do not want to do it by myself, i'm not enough confident.
If you find it...

Potatohead, could you please post another link to root.x16plus.v1.zip?
Mediafire removed the file, nowhere else to be found (according to google...)
Thanks in advance!

So did anyone else happen to pick this up from tinydeal while they had it for $79? Not sure if it's arriving with 5.1 or Remix, but this is good to know.

I followed the instructions and flashed boot-root.img successfully, however I'm unable to run adb remount in su.bat
it says "remount of system failed: Permission denied", "remount failed"
any ideas?
