Are their other Custom Recoveries than TWRP

[Ichijoe]

Alas with the upcoming Update, on Monday I find myself in a plexing place on how to reinstall SuperSU once more via a TRWP that just terminates on a Black Screen on my 4k TV.

I had thought to try patching though my Computer Monitor via a HDMI to DVI Connector. And, allthough it does work well enough once fully booted. There is not a chance in Hell of it liting up for TWRP, or even the Bootloader for that matter.

While TWRP may we'll be the best recovery I was wondering if anyone has ever bothered to port a different Recovery to the Shield (e.g. Philz, ClockworkMod etc..)

Just as an aside would any of these other Recoveries suffer from the same bug? It would be a PItA if I had to wait a week before I went to visit my Old Man just to go though the motion (and embarrassment), of having to flash SuperSU on his FHD TV again.

While this doesn't exactly answer your question, TWRP does have a CLI. Once installed and in TWRP recovery, and connected via ADB, I believe all you have to do is issue the TWRP command to see it's listing of features and other commands. I've flashed su and other .zips to my shield this way a few times.

Here's the relevant link and documentation.

So, example would be
adb shell
twrp install /sdcard/SuperSU.zip

Are those commands to be sent via ADB, or Fastboot, or something totally other again?

~crap... I spent way to much time trying to fix the Old Man's GPS (WinCE) Device. I can't read any more lol.

Ok I think I managed to get as far as ...

# twrp install /sdcard/SuperSU.zip
TWRP does not appear to be running. Waiting for TWRP to start . . .

I can only suspect that it's hanging on the Permissions change Switch that you have to swipe though before actually getting into TRWP.

It may or may not be helping that I'm also loading TWRP off of the /sdcard/ instead of bricking my recovery fully by installing it outright.

NOT that it would kill the Shield off or anything as drastic as this. But I doubt I'll ever see the recovery again. Lol to heck with 4k!

Ok so I went back and, actually installed TWRP as the Shield's Recovery. And now it's working. So if I have to reinstall SuperSU, as I suspect I'll will after tomorrow's Update to Nougat. Then I should hopefully be able to reinstall SuperSU though the ADB Shell (as above)...

Again thank you kindly a signed a 4k'er!
