[AT&T Samsung Galaxy S 4 General] JohnMonsour:
Impossible??

And you sir are the reason I am having trouble with motivation for un-locking this boot loader. I have been working on a downgrade method by resetting the q-fuse from 1 to 0 again. 4.3 Will put it at 2. And then put the what date that is bedded in the bootloader. AKA Aboot file. Anyways man I have put countless hours in on this and thousands of line of code using unsecured ADB.... 6758 commits to be exact.... Yeah the code is dirty And can eventually be cleaned up to about 40 lines.... In UNIX Linux android debugging bridge with r/w root privileges... It's just brute force. Trial and error. Please revise your comment. Other people are hard at work also.... One of my close friends is working on the Hardware side via j-tag..... We can write individual partitions..... Even MDB and MDL.... Just wait as a method will soon be available. Most likely resetting the fuse to 0 and then flashing stock MDB with ODIN and then we should all have Loki. I have been working on the bootloader. The 5 integrity checks using 3 different encryption. WTF!? Two times using 256 bit Sha-1 hash offset by 8. And the clearing of the ram during 1000 Decca-seconds not to mention 3 times. This is strong encryption. very very very strong. Im reversing the code that encrypts, checks, and decrypts. Once fully reversed, I will make modifications to the files and recompile them. Make a custom rom and run in Kitchen, then read the Log. If everything goes well in that department then I will release a flashable zip or tar for heimdall that patches the current bootloader with an unsecured version aka unlocked status..... Either can flash through SafeStrap or run the .sh script via ADB with root privledges. If I could get the sha-1 md5 hash then I would run it through rainbow tables to get the true encryption key. Once I have the key WE will have a way to generate our own signed Kernels and Bootloaders and Have full acess to this phone as it was intended by sammy in the first place. Android is open source and that's the way it should say.

Large corporations who strong arm the cell phone makers by threatening "We won't carry your phone if the bootloader is unlocked" The two largest in the business of Cellular services.... ATT and Verizon....... Ridiculous. And that is 80% of the users here in the states. So they have "Power and Sammy had to comply" Or else lose 80% of it's market roughly taking the company down and dropping stock and revenue. That's Why I support my local mom and pop shops rather than Tarzay or Wally World....

Don't blame Samsung blame the Large Corporations who Strong arm and Deebo around the provider. Samsung should have bluffed and said look if it's that big of a deal then we will market the phone ourselves for a cheap price factory sim unlocked and an insecure bootloader. With a vanilla android rom. That would have scared the big guys and caused them to compromise.

Be patient we have a plethora of people working on this.... We are getting closer everyday. We have mapped out the hardware to software components LB1 LB2, the stupid emulation that they have implemented. Knox and a Write protected stock recovery. with no options for fast-boot, ADB, Extended boot options as seen with some moto phones. This phone is capable of being the best. Once we get this bootloader unlocked then Development will skyrocket and we will all be happy. Yeah I have talked to a friend at samsung and they have the employees even scared to leak info/docs.....

Keep faith Dev's are at work on this. the way we look at it is an opportunity with an optimistic perspective. Where there is a will there is a way. one last thing: When Edison was said to by an individual you failed 7034 times at creating a light bulb, he simply replied, No I learned 7034 ways on how not to make a light bulb. All it takes is one day when one of us is in the zone chief. And wallah you won't be saying it is almost impossible then will you. Here at XDA!!!!! Are you kidding me. Sorry the site just said please do not use the I word as it does not exist here at XDA Devs. Thanks this is your one and only warning, next time will result in not having access to the unlock and or downgrade files and method. LMAO, Like all beautiful things, they aren't just made in a day.......
