This repository contains:

• adups_search_updates.py: A script that can search for new updates.
• original_apk: The decompiled original APK that searches for updates on the stock ROM.
• project: A Java project with code grabbed from the original APK. It can generate the data sent in the POST request to search for updates. This is no longer needed, use the Python script.

Searching, downloading & applying updates

• To search for updates, use the adups_search_updates.py script (note that it requires the tbm13_utils package).

  • It'll search updates for the TBT8A10 tablet, but you can use it for other devices by changing its variables to match your device's props

  RO_FOTA_OEM = 'incartech3326_10.0'
  RO_FOTA_DEVICE = 'TBT8A10'
  RO_PRODUCT_LOCALE = 'es-ES'
  RO_OPERATOR_OPTR = ''
  RO_FOTA_VERSION = 'TG08RK1_20231020_20231020-1806'

  • When an update is detected, the server seems to always give the latest OTA zip. The only difference is that depending on the RO_FOTA_VERSION you use, it'll give the corresponding zip needed to update from that version to the latest one.
  • If the RO_FOTA_VERSION you use is too old, the server may return that no updates are available. This is most likely because the OEM stopped building OTA packages for that version.

• To install the update on a device, it should be as easy as booting into recovery and sideloading the zip or installing it from an SD Card (Apply update from ADB and Apply update from SD card options)

• To patch system, vendor, boot or other images, extract the OTA zip and use these tools.

I'll be uploading TBT8A10 OTAs on Google Drive.
