Bin4ry,
I know how difficult it is sometimes to describe the process, but still.
If you could give us some more details on how original X10 was hacked, may be more people will join the efforts to root the mini.
As far as I understand it involves flashing a slightly patched firmware image that has root enabled, or is it ?
What should we try and where can we start, is there some firmware image we should try flashing ?
The debranding process seems to be the right way to begin, no ?
Not exactly. The rooting of the big X10 is no more a secret
It works with the fota application. The Fota App doesnt seem to verfify the signature fine in some areas of the DIFF which is provided in the fota.pkg.
The big deal is that SE has patched the method to start the FOTA Update from SD-Card in X10 R2 Firmwares and as i can see in the X10mini/pro Fota Client it is also disabled in the Release firmwares of those.
So 2 points have to be done to get the "same" method work here:
1.) Find a way to get the FOTA start the update from SD. At this point the FOTA Client copies the fota.pkg to "/cache/recovery/update_package". and reboots to SEMC-Recovery.
IF SEMC-Recovery detects hte "/cache/recovery/update_package" it starts the FOTA-Update automatically. IF not it show the yellow-triangle screen

2.) Get a original FOTA.pkg to alter or build a own one based on the big X10 packages and hope the signature of the updates is the same like on the big X10.
Here i have already done some work on the big one. Hopefully i'm soon able to build a own fota.pkg which makes no real update (only giving sh the su access). If i get it working on X10 i can try to port it to minis.
The big deal is point1! In new firmwares SE disables the system rights which are needed for executing debug_entry . BUT FOTA has still enough system priv's cause it can still reboot to recovery and write in superuser folders.
Thats the deal now.
BTW: I already looked into kernel source and all known vulns posted @ Securityfocus are patched or not compiled into kernel. :/
