These changes will do:

  • Allow Early Access updates at same time with Jolla C
  • Remove all intex stuff including activation SMS, Gaana, Aptoide

These changes will not do:

  • Jolla C LTE bands (this is hardware limitations)
  • Preinstalled android will remain

Changes persists after update, you will receive same updates as for Jolla C

Changes does not persists after factory reset, because phone factory backup still contains intex data

Simple steps:

  1. Open https://raw.githubusercontent.com/CODeRUS/aqua-fish-to-jolla-c/master/script.sh to check what script will do
  2. You need Developer Mode on
  3. You need to open your terminal or login to remote shell
  4. Next commands you should execute in terminal

    bash <(curl -s https://raw.githubusercontent.com/CODeRUS/aqua-fish-to-jolla-c/master/script.sh)
  5. Read prompt carefully, it will ask you to do actions 3 times.

  6. Profit!

Part 2: replacing intex recovery with modified Jolla C recovery

After doing these commands your changes will survive factory reset.

  1. Download https://coderus.openrepos.net/intexrecovery/mmcblk0p21_JollaC-
  2. Unpack and copy to sdcard
  3. Boot in recovery mode, enter shell
  4. Execute:

    mount /dev/mmcblk1p1 /mnt
    dd if=/mnt/mmcblk0p21.raw of=/dev/mmcblk0p21
  5. Wait until image will be copied to partition, no output will be produced.

Operation is finished when the copying is complete

How to revert if something failed?

@Magog how about that in reverse? But you need the feature-intex file on device iirc as you won't be able to download it again afterwards - @coderus you might want to add that as a security measure, load the required files for reverting to intex ahead of actually removing them.

Added info about revert :)

Thanks for your precious help. I will try it, but first will I get OTA/updates? If I change my Intex to Jolla C, will I get EA updates (on J1 I am EA)?

What does "make Aqua Fish to think it's Jolla C" mean? Does it change the LTE bands? Does it disable the SMS to Intex? Does it remove Gaanaa? Does it persist after an update or reset?
