I've modified Robin's boot.img to disable forced encryption.
With encryption gone, you'll be able to use TWRP to flash mods etc, without having to wipe your data every single time.
Other benefits include faster performance and better battery life.

Unfortunately, to actually remove the encryption - you will need to format one last time.
But once done and set up, you'll see that your phone is no longer encrypted.


Requirements:
- Unlocked bootloader
- PC / Mac
- fastboot (+ USB drivers if needed) -or- existing TWRP install

Instructions:

If you're using TWRP:
1. Perform a factory reset from within TWRP and reboot back into it (Note: This isn't required if your upgrading from an existing unencrypted stock install).
2. Flash the included zip file
3. Reboot

Manual flash using fastboot:
1. Download the zip and extract the boot.img file
2. Reboot your Robin into fastboot mode
3. Flash using the command:
Code:
fastboot -i 0x2c3f flash boot boot.img
4. Factory reset. (This isn't required if your Robin is already unecrypted and you simply want to update your /boot)
Note: If you skip this step, your phone will remain encrypted.
5. Reboot

Rollback:
1. Re-Enable encryption from Settings -> Security -> Encrypt Phone
2. Flash the stock boot.img

Thanks, worked well!
Thank tested, will se if it gets any faster. Have been having some problem with lag that comes from time to time that I haven't seen on other devices.

Otherwise, great to see support for such a small phone!

Unfortunately no, because the OTA includes an updated delta for the kernel as well (which means the /boot needs to be 100% stock).
If you want to install via the OTA, you need to restore the stock boot.img (and the system partition - if you're rooted or modified it in any way, and the recovery too, if you have TWRP installed).

Alternatively, you may simply flash the updated stock ROM zip on top of your existing install - just be sure to flash the new boot.img zip immediately after (as well as SuperSU and any other mods you may have, if you want to preserve your current setup).

This mod only allows you to use your phone unencrypted - it shouldn't affect your battery or WiFi. Are you sure you flashed the correct version?
Goto Settings - About. If you're on the June 1 ROM (Build 00WW_1_350) then your kernel version should say 3.10.84 Wed Jun 1. If these numbers do not match then restore to the latest factory image/ROM and start over. Also, have you tried a factory reset yet?
