Yes. Any custom binaries will trip the warranty bit.

Thanks. I guess it makes more sense to just flash TWRP then.

TWRP will also trip the warranty bit. Anything that has not been officially released by samsung will have the same effect.

I understand that but figured I might as well install TWRP if I was going to trip the bit anyway

Yep, boot and recovery are the main offenders, now to get get a Samsung signed TWRP... That would work, pity it's a pipe dream....

Software Update

anyone else get the prompt to update the software? are you going to update?
Got it and did it 2 days ago
Same and same
probably too early to know, does anyone know if this update will affect root? coming from htc, i remember updates were frowned upon as they can make rooting more difficult.

Got phone few days ago and update popped up. I postponed it so its in my notification bar until someone confirms device can be rooted on update safely.

below is the link I used. The battery drain is bad but manageable. I think it puts the wrong recovery on the phone, but it does root the phone. I was able to use titanium again :highfive:

The Odin you need is in the Zip file.

[SM-G930/Exynos] CF-Auto-Root

CF-Auto-Root is now available from the repo - http://autoroot.chainfire.eu/
Before flashing, make sure you have enabled "OEM unlock" from "Developer Settings" !
Note that CFAR's display code isn't yet compatible with the S7, as such, there is no output on screen. This means that after flashing with ODIN, the device will only show you the S7 logo, and it seems like nothing happens. Just leave the device alone for 5 minutes. It'll reboot a few times, then boot into Android, but now you have root.
If it still doesn't do anything after 5 minutes, something has gone wrong, and you should probably reflash your stock boot.img and recovery.img.
Great work! Thank you.
Any opinion about if it would work with G935/Exynos Edge?
Sry! Didn't see your tweet!

Right, I got that, just wondering if anyone has actually had success.
This will not work on G930A.
@Chainfire
Is dm-verity disabled when you flash CF-Auto-Root? Can I make system modifications like CSC feature expert?
How will this not wipe your phone if it includes unlocking the bootloader...also will this work on the W8 Canadian variant?
Echt weer een super prestatie van je @Chainfire !
Tomorrow my S7 will arrive and of course I need root to restore Titanium Backups of my old S5 (only data, not the progs).
Just to be sure, rooting with CF-Autoroot will not trip my Knox counter right ?

Does this leave stock recovery or TWRP?
you'll have to flash this back. once autoroot is done there is no need in leaving the boot and recovery img from chainfire on your phone.
get your hands on the corresponding boot and recovery images for your phone and flash them back after you are done.
knox will be tripped anyway, so you may also flash twrp or anything else.

Root without unlocking/wipe?

Is there some way to get root without unlocking the bootloader/wiping?
AFAIK root requires a custom recovery, to flash a custom recovery requires unlocked bootloader, so simple answer is no.

Not necessary, coming from other devices. I am no noob, I know what BL is, but some manufacturers tie certain features to locked BL. Sony for example cripples camera when you unlock.

oneplus works same whether the bootlader is locked or unlocked. the only downside is as soon as you lock or unlock your bootloader your phone is wiped completely.

Otas dont work with twrp, oneplus releases a singed ota update on their forums usually within a week or two after the official ota. These singned updates can be flashed via twrp.

The only downside to unlocking the BL on the OP3 is that you get a warning message (http://i.imgur.com/88NcI2K.jpg) when booting the phone. Lots of people hate it, i like it personally. It makes pressing button combos to get into fastboot/recovery obsolete.

If flashing is the only way to root the device, then yes.
And unfortunately flashing seems to be the only way.

The solution (I think) would be to wipe data and flash the entire stock image for your phone, then re-lock the bootloader. This will make sure that any folders/files pertaining to being rooted are gone and shouldn't cause any problems when it comes to validating your OS. Just make sure you properly unrooted SU by using their uninstaller/unroot tool before wiping and reflashing.

Flash. all to both slots and be sure to include -w
Out of curiosity, why do you even wish to lock the bootloader? Especially with the numerous horror stories of users unable to resurrect a bootlooping device (rather simple to fix if unlocked) because their bootloader is locked.

Just an FYI, here's someone that locked their bl. Only 2 reasons I can see this as necessary is RMA, and Android pay. And Android pay works with magisk, so really only one reason.

Question any custom recovery

There are no custom recoveries.

How long do you think it would take to develop a Custom Recovery for this terminal?
It's essentially a modified cebu (G9 Power) for which a TWRP exists. It's Android 11 being the release OS that's blocking recovery development.

Yeah. MIght be the sole reason that development for this device to never take off
i might consider building a recovery for the device (i have managed to successfully build twrp for a mediatek device)
ok weirdly the files that need to be extracted arent being extracted but i have found the kernel source code for caprip https://github.com/MotorolaMobilityLLC/kernel-msm/releases/tag/MMI-RRCS31.Q1-3-34-1-4
I had the same issue attempting a GSI overlay; without the framework "glue" the kernel sources are pretty useless. I'm sure we'll get to grips with Android 11 devices eventually, hopefully in time for Lenotorola abandoning us on the obsolete pile.
On that note, it may be worth delaying the "ooh shiny" moment when 12 is released for this device. You can always apply an existing upgrade if needed but manufacturers have a habit of making backtracking, particularly RIL and bootloader, incredibly and unnecessarily difficult.

If you're rooted, if you need a file browser that allows you to mount "read/write" on that directory. I heavily reccommend against doing that if you don't know what you're doing.
And since you didn't already know that you had to mount Read/Write, i assume you don't know what you're doing. Don't mess with it.
