[Samsung Galaxy A8+ (2018) Guides, News, & Discussi] mark0021:
Its been a long time since I had this phone, June 2018 when I had my first "A" series phone. Since then, I'm planning to root it right away but reading a bunch of forum saying new security patch that samsung did some tells its wosrt than frp lovked something about rmm locked and they say if it happens, theres no way to fix the device unless you have to wait for 7 days without turning off the phone and stay connected and after a week of waiting the "OEM Unlock" option will now be available. There after, with that option now ticked you can now proceed to the common thing here in xda usually do, our only and always be our favorite to do... which is "FLASHING" after that is "CUSTOMIZING" for us to have a unique device amongst others and also enhancing anything to the very limit can handle, having an app that we need and removes those useless bloatwares...

Flashing, rooting and customizing sure is fun and satisfies your needs but it comes with risk. Even we have same device model flashing custom rom some device can face bugs some is not, some will experience less issue and some even worst so that caution about the disclaimer always there and proceeding means you take the risk and no one but your self will be the only person to blame so if you have no idea what you're doing just stop for a while.

Like me, if you really want to make it happen, all you need to do is read, study and understand, because in some complicated proceedure, there's no room for error and you'll end up crying with a dead phone...

Few months ago from time to time visiting xda, I have a positive feeling and completely aware that I can now flash my A8+ 2018 without a doubt, just a piece of cake!

While reviewing step by step, downloaded everything, preparing for every "what if" then the problem came up...

Well, just a little problem, but that small little problem thing stops me to proceed.

To fully understand the procedure and , it took me time, very long waiting time. Passing almost a year now and I'm still stock with the same phone running also in stock os.

Although it's in the "mid-end" phone, having such as this device for almost a year was long enough to love it, enough to get used to it.

Until now, this mid-end phone with stock Android 8.0.0 official operating system runs impressively very smooth and not a single issue ever experienced and to be honest, it exceeds my expectations but still, there's a limitation and that's the customization. To make it possible, I need access to these "four letters" R O O T.

Accessing it is not possible, I need the superuser to grant me permission to access the root and su ofcourse is not just like the ordinary apk that can easily be installed, it will be flash, not in odin but recovery but flashing it will not be possible because that su.zip file cannot be flashed with the stock recovery, but custom recovery can like twrp.

It must be flashed via odin, after flashing twrp you can now flash su and congrats, your done rooting...

How I wish rooting todays device was that easy do...

BUT IT'S NOT!

IT'S GETTING MUCH COMPLICATED NOW...

THANKS TO THE GENIUSES HERE IN THE XDA!

Like what I said, it took me too long to fully understand, long enough to like it a lot that putting lots of apps, games, gig to gig files in my secured folder, dozen of duplicated media apps and multiple accounts, in short "LOTS OF THINGS" and for me all those are important and I can't afford to lose a single file...

In the step by step procedure, when everything was already correct settings and before to click and start the flashing of twrp recovery via odin there's instructed or warning that must not be ignored, something like this:

BE SURE "AUTO-REBOOT" IS NOT CHECKED and then after the successful flashing and see the PASS message, force reboot your phone (Press and hold Power and Vol -+ buttons together) and once the screen is off, press and hold Power and Vol + buttons together to boot in TWRP.

Not following the "EXCACT" instruction? Well, it still boot hopefully to normal but then if you try to check if the custom recovery is there... SURPRISE! Nothing's new! Just the same old samsung recovery and you just made your newly flashed recovery useless because it will revert back to stock recovery, instantly replace the twrp recovery you've flashed. That's the reason it have to force reboot to recovery mode.

But there's more, if you start the procedure without enabling the OEM Unlocked somehow kick-in the device "enhanced" security and trip the RMM "TO LOCKED" (not locked yet but it will as soon as the device reboot) if that happens, your'e in some kind of trouble now because at that moment the OEM automatically locked meaning the bootloader will also locked and also means NO FLASHING CAN BE MADE and there's no way the OEM to unlocked because the "OEM Unlocked" option in the developer setting will removed and "UNABLE" to access it for exactly 7 days and forcing odin to flash it again without waiting the said time not an option because doing so while OEM is locked will trip next the Factory Reset Protection aka FRP Locked and it's very hassle. Doing it again and again will not help, the 7 days period will only reset 0 so if it happen, just be patient.

Now back to:

BE SURE "AUTO-REBOOT" IS NOT CHECKED

after successfully flashing your custom recovery it will manage to reboot to your new recovery which is twrp (preferably latest)

Next step to do is yet very simple and easy up to the last step of the procedure...

***Next step to do is very simple and easy up to the last step of the procedure...

Once TWRP is booted you first need to decrypt your /data partition. To do so touch Wipe>Format Data and follow the instructions in screen.

Can do it with a couple of swipes to wipe (format data), reboot to recovery again flash su, flash no-verity and also RMM bypass zip just for sure... after that fun stuff can now be available, flash custom roms, blah.. blah.. etc. Boot normally without worries.

About the:

" ***Next step to do is very simple and easy "(above)

Yet very simple and very easy, that's the actual problem dive-in...

As I've mentioned above about having this device from such time and putting lots of apps, games, gig to gig files in my secured folder, dozen of duplicated media apps and multiple accounts, in short "LOTS OF THINGS"

The next step was about formatting and it's a must thing to do to make it work and using unrooted device is impossible to make NANdroid backup, the 64Gb internal storage were almost full and because of that it makes much harder backing-up...

Any advise?

Please help...
