Root Galaxy S6 SM-G920F and S6 Edge SM-G925F 5.1.1 update using the “Unikernel”. This root method has been tried and tested on almost all Galaxy S6 and S6 Edge variants. But unfortunately, the root only perfectly worked on some select variants due to the recent updates which are being patched. The “Unikernel” is basically a root ejected “kernel”, so flashing the Unikernel into the Galaxy S6 SM-G920F and S6 Edge SM-G925F will technically do the rooting process. Now before you begin with, just do take note and keep this in mind, that rooting your Galaxy S6 and S6 Edge will trip the KNOX counter. This will eventually void the warranty of your phone. Aside from that, some downside on a rooted phone; (1) Some apps will stop working perfectly. (2) Your phone will no longer received any official software update. Important Reminders: To those who have just heard about Android rooting, then here are some few important facts about rooting your Galaxy S6 SM-G920F and S6 Edge SM-G925F before you take the plunge. 1. Void the warranty of your Galaxy S6 / S6 Edge. Yes, it technically voids the warranty of your Galaxy S6. Some dealers might not render a rooted phone. So if somehow there is something might go wrong with your phone and you have to send it back to your dealer for the fix, then you might have to cover all the paperweight if they’ve found out that it was rooted. 2. This root method will trip KNOX. KNOX basically an app which also include a security counter that is hidden in the system data. A tripped KNOX will no longer work and this is not irreversible. This is a new security policy from the manufacturer and the dealer and was pre-installed on all Galaxy S6 and S6 Edge devices, either its unlocked to a carrier branded models. You can see this stuff when you reboot your Galaxy S6 and S6 Edge into download mode. You can access it when the phone is turned off, then by pressing Volume Down, Home, Power button at the same time. And then the Volume up. The untouched, unrooted and unmodified Galaxy S6 and S6 Edge simply shows like this: CURRENT BINARY: Official SYSTEM STATUS: Official KNOX WARRANTY VOID: 0 (0x0000) But a rooted and modified Galaxy S6 and S6 Edge will llok such as this: CURRENT BINARY: Custom SYSTEM STATUS: Custom KNOX WARRANTY VOID: 1 (0x0500) It will technically show you the system has been modified and already set into “custom” from the default “official”. Then KNOX Warranty void counter has been tripped by showing the number “1 (0x0500)”. 3. You will no longer receive a Software Update via OTA. Samsung frequently rolls out software updates which often arrives once a month or two. New updates particularly bring several improvements, bug-fixes, and other system enhancements. Now, a rooted Galaxy S6 cannot get new software update anymore. During the software update processes, there’s a consistency check happens. It will basically check the phone from what software version it has, was it is official or customize and was it is rooted or not. So once it finds out the phone was rooted or running on an unofficial firmware; the update will tell the user that there is something with the phone’s system OS. So oftentimes some users who don’t know about it, they can get a message that says something like “The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Smart Switch on your computer or visit a customer service center.” or similar message to that. What particular firmware build version on Galaxy S6 SM-G920F and S6 Edge SM-G925F do this root method will work? Once on very 5.1.1 software update do have different build numbers. Each update is accompanied by a new “Baseband” version and “Kernel” version. In some case, the kernel version is still the same to the previously released build version. Now, according to the Unikernel developer himself (g.lewarne), this root kernel is based on 5.1.1 update such as BOFJ and COF8. So we aren’t sure if this root method will still work on any recent and future 5.1.1 update. So before you dive into the plunge and just to ensure that everything will be fine, just before you root your Galaxy S6 SM-G920F and / or Galaxy S6 Edge SM-G925F, I also list down the build numbers to which this root method can be applied for. Note: This list will be updated if and when there are a newer released version of firmware updates. Noting that the Unikernel will also get a duly updated version every now and then prior to match the newly released build number. So in order for you to root successfully without any issue your device must meet the following build number accordingly, or else the root will not work.
