CAT B35, the indestructible rugged with KaiOS operating system, has finally achieved jailbreak and root. This was possible using the correct firehose, available on edl.bananahackers.net, the right tools (Miraclebox or EDL.PY) and the device started in EDL mode.
The methods are 2.
Method 1:
Speeduploop used Miraclebox to get a copy of the partition /data, he manually installed the ADBRoot apps (which you can find in the "temporary root" section of the BananaHackers website) and FTPD (in the "Settings" section of the B-Hackers Store) with the necessary permits, to then reinsert the partition in its place. Nothing could be simpler, apart from the risk of continuous reboot, but everything went the right way.
Method 2:
Luxferre first modified the /boot partition using the aboot tool to modify Android /boot partitions and enable root permissions, keeping an original copy to be re-flashed in case future updates are obtained.
Subsequently Luxferre modified the large image of the userdata partition to activate the "Developer" menu by reading it with a Hex-editor (not to be confused with Text-editor) and modifying a bit (8 bytes) to then re-flash the partition.
This method prevents the device from rebooting continuously after the operation.
You will find these detailed guides by browsing the CAT B35 page of the BananaHackers website.
I can't provide a video of the operation because that device is not yet in my possession.
This new method to perform the jailbreak and the root of the devices is applicable on all devices with known firehose.
And thanks to the new Luxferre tool based on EDL.PY and perfected for Qualcomm devices based on KaiOS it is possible to perform the operation on macOS, Linux and Windows.
You will find more details on the BananaHackers website in the "Development" section under EDL.
As far as GerdaOS is concerned, release times will be even longer due to these new discoveries, which also involve Alcatel Cingular Flip 2.
We listen to the words of Luxferre about it:
---------------------------------------
I honestly hope that it can be completed within this month. However, I'd like to point out several things:
1. Without at least one working tunneling system implementation, be it OpenVPN, PPTP or something else, a new version, where just an API layer is upped, would be a bit pointless. Same goes about RIL alerting about stealth-ping messages and a built-in utility for user-agent spoofing and proxy adjustment.
2. Given the current situation with firehose loaders, an effort to modularize the build for the multiplatform is something we also need to consider. Wouldn't it be wonderful if the next alpha would work on 8110, CAT B35 and Alcatel Cingular Flip 2, where there would be some compatibility layer to adapt to partition layout, modem and keyboard, and everything else would be the same? And also, build process needs to be reworked anyway (if you remember, cloud boot image builds are somewhat broken).
3. And by the way, after seeing the significant UI/UX changes in 2.5.1 (on B35), I'd actually like to base the new alpha build upon it instead of what we have in v16. So the porting/merging effort would be a bit longer than expected.
But still, let me be perfectly clear: in this custom ROM, privacy/security mean much more than UI/UX. So, if necessary, the next build will be postponed until a more or less complete of security features is implemented. And yes, if that means completely losing track of upstream UI/API patches, then so be it. The upcoming alpha revamp (based upon v16/v17/2.5.1) may be the last update where this track will be preserved. Afterwards, things may go in a completely different direction, certainly not following then one corps want us to go.
Stay tuned and be patient.
----------------------------------------
All clear then? GerdaOS will therefore become a unique ROM, for Nokia 8110, but will also extend support to Alcatel and CAT, adapting perfectly to different hardware as does Android, or more generally a Linux distro.
This is what I call "support"!
