Supersu is stuck at installing update

[andsa]

I have rebooted it as it says if the update takes longer than 5 min, and it's still stuck.

I even downloaded superuser and checked the binary update, but it wwas a fail the instant i tried to download it from the superuser app instead of supersu.

Will the device boot normally? If so download the latest v2.46 update ZIP from here, copy to internal storage or sdcard, then flash from your custom recovery e.g. CWM, TWRP.

p.s. knowing the device you are having the problem with will help with finding a solution.

Sorry, the device is nvidia shield portable nadroid 5.1

And how do i use that zip? (fairly noob to rooting and such)

@andsa, are you actually rooted (and can you tell us how you rooted and what your device is)?

I've seen people report a similar issue when trying to update the su binary from the SuperSU app, but if you are not rooted, that won't work, of course.

Just asking in case this is the case/cause .

I used this guide

I thought the flashing of the rooting img i flashed rooted it, but apparently not..

Ah, thanks, @andsa .

So, just to make sure you're actually rooted, can you download and install Root Checker from the Play Store and verify that it says that you are rooted?

 

[andsa]

"Root access is not properly installed" was what the root checker said after 2 attempts when i "granted it access"

It is because the 2.46 upodate of supersu fails or can't fetch the update for the binary at all.

Yeah, it sounds like you didn't get root properly installed--i.e., perhaps you didn't get the bootloader unlocked (which would explain why the UPDATE-SuperSU-v2.46.zip didn't flash successfully)?

I skimmed through the page from the link you cited above for rooting your device...did you encounter any issues, warnings, errors while doing this and can you double-check that you bootloader is indeed unlocked?

edit: another thought--were you able to actually run the custom recovery (CWM or TWRP) to try to flash the .zip file?

The bootloader is unlocked, but it seems the supersu didn't flash properly even after i have flashed it twice.

No warnings or anything. Everything went successful.

I haven't flashed CWM for years after my little bricking incident when i tried clockwork mod and cyanogenmod 7 back when lg optimus 2x and htc one X was out

The only other thing I could think of would be to reboot into custom recovery and see if you can get a root "#" prompt ("adb shell" then "su"):

c:\> adb shell
$ su
#​

That should help let you know that you're rooted at least from an adb prompt.

Also, did you say you are using the SuperUser or SuperSU app?

SuperSU should be getting auto-installed for you from flashing the UPDATE-SuperSU-v2.46.zip file...you won't need both SuperUser and SuperSU (and probably don't want to have them both installed in fact).

 

[andsa]

I was originally trying to only use the supersu 2.46 version that i flashed with the shield root img in the root folder.

As you haven't mentioned installing another recovery I'm assuming that you don't actually have one on the device, which will make fixing the problem... problematic.

My suggestion is to install recovery and SuperSU as per this post. There's also a TWRP recovery available here, if you#d prefer that to CWM.
