ReplyDeletePls tell me whether its boot.img or android system related problem.
Does this rom include vowifi calling feature?...btw nice blog
ReplyDeleteI don't know about it but if it needs separate hardware then it's not possible on Jio phone but if not need hardware then there maybe source codes hidden inside.
DeleteThanks for appreciation.
Initially worked well but now Network issue, sim unable to catch network.
ReplyDeleteMaybe your firmware is different than us or older or maybe something went wrong with IMEI number because we did not get any of this issue and everything is documented by me already also tested by me and other people.
DeleteLet me know how I can help to release Gerda OS for F61F Spreadtrum Variant of JioPhone

ReplyDeletegoogle se imei tool download kake flash kar lo theak ho jaye ga mere bhi ho gaya tha
Deletecalling and other sim (airtel, vi) not working in this please update that
ReplyDeletewill Predictive text will work here ?
ReplyDeleteWill your process unlock the other vendors Network? If yes how, i have followed all the steps which are mentioned in your post.
ReplyDeleteThe unlock procedure for other network is quite complicated, the modem have it's own firmware that too in it's own instruction set with encrypted form.
DeleteWe can unlock it, but I don't want to perform such complicated process on my limited time, it could be dangerous for modem itself.
it will completely out of your mind because it require lots of instruction set and Reverse engineering knowledge, if you have one I could only hint you.
These are following:
1. Extract original modem.img
2. Unpack it
3. You'll find parts of binary inside it, concat them. (it's up to you, how you do it)
4. Open it in it's Qualcomm specific decompile kit
5. Patch network detection logic that resist other vendors
6. Repack it
7. Again make its parts as it was before
8. Make modem.img file from it
9. Flash it.
Now it's up to you how you do it.
