Idea: hwid/cpid bypass with desolder - GSM-Forum

Stunman112 · 03-03-2017, 03:04

If hwid/cpid is limiting us for Samsung cert writing maybe we can begin to look at the hardware (nands) where this new technology or security is based. Similar idea would be like the iCloud hardware bypassing method with iphones. Can critical info regarding the keys be stored here and accessed via socket reader? Lets discuss ideas here

You mean, if can be bypassed by changin NAND/EMMC chips. Then writing a custom IMEI.
Aye AYe. A keen eye, a thoughtful gesture

Yes i think it is all too possible! It took a long time for hardware bypassing to be public knowledge with the Apple devices. Samsung has jumped aboard with Apple in that they are locking down the devices with hardware based keys to prevent certian modifications or unlocks.

My thoughts are about getting whatever chip that holds the key and somehow decrypting it. When this is done we may just end up finding that unique token. This needs to be dove into before SS catches on...

Anyone with information please dont hesitate to drop a comment or idea! This can be the future even with the S8 and other new devices following this new security scheme.

Sure you FORGOT that CPID Device BASED haven't ANY EMMC Chip, but working with UFS System!!!

If Not Know the difference between EMMC and UFS System, first of all try to search this!!!

Basic difference is the in way the chips transfer data. (2 way communication with UFS vs. single direction on EMMC) but the idea is the same. It is to gain access to the information stored on the medium that will get us closer to what were looking for. That key!

Placement on S7 is the package FBGA153

Interest topic. Your idea might be possible, but how do you plan to decrypt the content of the EMMC?

why use solder or iron? you can buy cert. cert havent any risk. some version not need root. you can write direct.

First ow write Uselless things next time Search what's CPID in HW.

You cannot Write Any CERT Lol if not the Original one.

or

Only with KNOX "Warranty Void 0" (0X000), must need of do other most complicate procedure and Yes can write one "Generate" Cert only for this device compatible!!!!

The idea of this post is to find ways to GET cpid. Once we have cpid we can write cert with ease without server.
