[Galaxy Tab 4 Q&A, Help & Troubleshooting] SimpTheChimp:
I have a Samsung Galaxy Tab 4 8” SM-T330NU running 5.1.1. The box tells me the ‘real’ model is SM-T330NYKAXAR. I decided to root the phone, because I want to get to Marshmallow and to get rid of this extra bloat where. (I will mention I have a good amount of experience rooting, including just rooting my Droid Turbo).

Anyway, after a lot of looking around the forums, I decided to use the CF-AutoRoot method (CF-Auto-Root-milletwifiue-milletwifiue-smt330nu) to root. I got Odin and installed it (along with the Samsung drivers) onto my Windows 10 PC; set debugging, on; and ran Odin. I followed the directions and it appeared to root properly; and I got to CWM recovery. Woo hoo! (Or so I thought)

So then after making sure I can get into recovery, I rebooted back into my stock ROM. Unfortunately, I got stuck at the Samsung logo; tried rebooting multiple times; even did a factory reset/wipe (as per instructions I saw on the forum) but to no avail. (Even let it set for over an hour but it never got past the Samsung logo).

After some more reading, I figured I might as well go ahead and flash a new ROM; so I think (if I remember correctly) I tried the JazzROM. It got up to about 69% and then it just quit - screen went black, and then it rebooted back to Odin mode. Obviously it didn’t work; then when I tried to get back into recovery to wipe and try the flash again, I got the message ‘Cannot mount \system - invalid argument’.

Again, after much reading and trying, I was able to get TWRP recovery installed and then wiped/formatted the system partition, which I had read would help get rid of that error. And it did seem to fix it.

So I can re-root with Odin without any issues; I can get to Recovery (either CWM or TWRP depending on which I flash), but no matter what I do, it either gets about 2/3 the way thru the flash process and then reboots back to Odin mode; or (using TWRP) I can get it certain ROMS to flash successfully, but after rebooting it goes right to Odin mode (saying it could not do normal boot). I even tried loading a stock, with the same result.

Which leads me to my first question: Exactly which ‘stock’ file should I be loading? I am having a hard time finding one - either it leads me to a dead end, or the download doesn’t work.

- When in CWM recovery, it shows the following:

At the top:

LMY47X.T330NUUEU1BOI1

Bottom:

#Manual Mode#

— Applying Multi-CSC...

Applied the CSC-code : XAR

Successfully applied multi-CSC.

Are these correct?

- When TWRP is installed (3.0.0-3) it starts by asking me about the ‘Unmodified System Partition’ and whether it should be kept read-only or allow modifications. I assume allow mods? Otherwise I don’t see how you could apply a new ROM? (I haven’t seen this in a while, not in my install of TWRP to the Droid Turbo). So just want to make sure I am selecting the right option.

- I am also concerned about whether I am using the right packages for this tablet. Based upon what I see on the box and sticker (which I still have) this should use the stock ROM LMY47K.T330NUUEU1BOI1 model; but I’ve also seen things referring to a BOG1 model? Mine is the T330NU English and (I assume) US model since I am in the US.

Any ideas as to what is going on? If I can at least get back to stock I could then start from scratch with the appropriate info; or just install one of the new ROMS (I’ve tried Jazz, Dirty Unicorns, UltraStock). I don’t think I am ‘bricked’ because if so I wouldn’t be able to get to Odin or recovery. Any help appreciated here. Thanks!
