Tecno pushes Camon CX Air-H3713A-N-170618V105 HIOS 2.2.0 OTA update

A few days ago, Tecno began rolling out the Camon CX Air-H3713A-N-170618V105 OTA update. This is coming shortly after the Camon CX received bugfix OTA updates. With less than a month to the highly anticipated August, the Tecno community is hoping Tecno truly releases Nougat updates for older Tecno devices as promised. You can listen to the podcast on H-Tech Radio for more on that announcement by Tecno. You would recall that the Tecno Camon CX and Camon CX Air shipped with Android 7.0 (Nougat) so bugfix OTAs are all we expect for now, not Android O (8.0).

So what is featured in this update?

Some features include:

  • Version update: CX Air-H3713A-N-170618V105 (from CX Air-H3713A1-N-170330V91 )
  • Update from HIOS 2.0 to 2.2.0
  • Updated Google Security Patch to 6.5 (June 5 2017 Android security patch level)
  • Merged the lastest GPRS parameters
  • Increased 2db of the receiver sound
  • Turned on the Fingerprint capture by default
  • Fixed the issue where the Flashlight was inadvertently enabled under the leather case mode

Prerequisites for updating your Tecno Camon CX Air

  1. Backup your current firmware

    : I strongly recommend you dump your current firmware using a Chinese box like Miracle Box or Infinity Chinese Miracle II (MTK)

  2. Ensure to unroot

    : As at the time of this post, Team Hovatek has not published a rooting guide for the Tecno Camon CX Air, only the Tecno Camon CX has been rooted . If you have already rooted your Camon CX Air by the time you find this post then its very important you unroot your Tecno Camon CX Air using the Tecno Camon CX Air stock ROM / firmware . Also ensure the phone is running on stock recovery, not a custom recovery.

  3. Charge the battery

    : Make sure the battery is charged above 50%. If you can have it connected to power during the update then good; you don’t want an interrupted OTA update
