How to install NFC on Sony Smartwatch 3
This is a guide to install NFC on your Sony Smartwatch 3. If anything goes wrong along the way, go to step 3 and start over.
Warning, following this guide will void your warranty
There are several guides how to do this, here is one:
If this link doesn't work, just Google it.
On the watch goto "Settings -> About" and click on "Build number" until it says "You are now a developer".
Goto "Settings -> Developer options -> ADB debugging" and enable.
On the watch goto "Settings -> About". Scroll down until you see "Build number". It will say something like LWX48F.
If it says "LCA43", you are lucky! Goto section 6.
If it starts with "M". Your version is too new and needs to be downgraded. Goto section 4.
If it starts with "L". Your version is too old and needs to be upgraded. Goto section 5.
This guide is based on http://forum.xda-developers.com/smartwatch-3/orig-development/tut-how-to-fix-swr50-fastboot-t3258918
Start by downloading all the files from https://drive.google.com/folderview?id=0B14BmzmcIZ4cVDBjRnliUDVXU1k&usp=drive_web
Open an console / terminal / cmd and navigate to your adb Installation. Ensure SWR50.img & twrpnew.img are copied into this specific folder.
Reboot into fastboot
-
adb reboot bootloader(Wait until the watch says "Running Fastboot") -
fastboot devices
If the list is empty, you have to install the fastboot drivers first:
-
Open the device Manager
-
Right click on "tetra" -> "Update Driver"
-
"Search the computer for driver software" -> "Select from a list of available drivers on my computer"
-
Select "Android Bootloader Interface" and confirm all dialogs
Write into your cmd:
-
fastboot oem unlock -
fastboot oem unlock(Yes, twice) -
fastboot format cache -
fastboot format userdata -
fastboot flash recovery SWR50.img -
fastboot boot twrpnew.img
The phone will now reboot and you should see a menu on the watch. If it's stuck in boot sequence, goto ERR1 and then try "fastboot boot twrp.img".
adb push SWR50.zip /sdcard/
Press "Install" on the watch. Press SWR50.zip and install.
After installation, press back. Goto "Wipe" and slide to factory reset.
Reboot device.
Redo step 2.
Install system updates until it says LCA43 under "Settings -> About -> Build number". You can see system update progress by going to "Settings -> About -> System updates".
Download file tetra_nfc_LCA43_0.2.zip from http://forum.xda-developers.com/smartwatch-3/orig-development/sony-smartwatch-3-nfc-support-package-t3219713
Do "adb reboot bootloader" and wait until the watch states "Running Fastboot".
Write:
-
fastboot oem unlock -
fastboot oem unlock(yes, twice) -
fastboot boot twrpnew.img -
adb push tetra_nfc_LCA43_0.2.zip /sdcard/
On the watch you should see a menu. Press "Install" and locate the file under sdcard. Install it, then reboot.
If it boots, congratulations! Your watch now supports NFC!
If it doesn't work, try to factory reset: First goto ERR1, after that write:
-
fastboot erase userdata -
fastboot erase cache -
fastboot reboot
If it still doesn't work, goto retry. Do step 4, 5, 6 again.
If you can't get to fastboot by running "adb reboot bootloader", do this:
- Hold power button until watch turns off.
- Unplug watch from computer.
- Hold power button until a blue screen appear. DO NOT INSERT USB! (Yes, I know it tells you to)
