Greetings,
I'm having trouble bypassing a Samsung SM-A510F pattern lock for the police. I tried to bypass it using the UFED Touch and by installing TWRP, but both failed. The phone has FAP Lock on, so it wasn't possible to install TWRP ( what does FAP lock exactly mean? Everytime I try to get more information on the the FAP lock I only find articles related to the FRP lock).
After some more research I found a tool called "chimeratool". It seems quite cheap compared to other programs we already have in use and the SM-A510F can be unlocked regarding their homepage. Before it can get unlocked first the FRP lock should be removed. Does anybody know of chimeratool and can confirm that by unlocking FRP no user date is deleted?
Or does anyone no of a way to unlock FAP so that I can get TWRP on the phone?
fastboot oem unlock will wipe your device and you can't access the device menu to safely unlock it, since you don't got access to it.
I sent you a PM.
There are 2 solution…..
1) ISP eMMC - will be fastest way and non destructive - you need open phone, make a dump using ISP eMMC from phone - then you can analyse it in PA (if it's 5.x PA will give you pattern from rainbow table or you can generate at your own, if it's 6.x it's uses Crypt so Gatekeeper - we can read code from such phone if you will send us gatekeeper file). Full procedure takes from 1 hour to 8 hours to read dump depends of CLK speed and bus width of eMMC.
2) Chip Off - invasive methode, you will need remove chip, make dump of it, after you can put it back … solution are same as in first case so after analyse it in PA.
All of those solutions are available ONLY if encryption in phone are switched OFF so when user not enable it, otherwise User Partition (UserData ROM1) will ne crypted and you will get garbage.
Thank you both for your quick answers! I'll give the ISP eMMC method a try. )
Bolo is right, but there is a 3rd option as well, our in-lab opening method.
If our in-lab method works, it gives result no matter of GateKeeper or not, encryption or not, locked BL or not, rooted or not, OTG capable or not, etc.
Trying is for free, if our method fails (yes, sometimes it does!), there are no costs.
However, if there are results and we unlock a device, our costs are between USD 1500 up to USD 5000 depending on the complexity of the task.
