When I came back to stock too, I had to do a factory reset after flash it.

Yeah all you needed to do was wipe system, and all the caches and also data. Then flash in odin

[Q] already installed stock firmware, can't install stock kernels or recovery

I tried to unroot my phone after getting stuck in a cyanogen bootloop a while back. I managed to get into recovery and install stock firmware via Odin. I did not however install the stock kernel or stock recovery. I am now in a stock t-mobile bootloop. I'm not sure what to do, I have been unable to get into recovery thus far, but I can keep trying. What can I do?

Can you get in Download mode? To work with Odin you must be in Download mode, not recovery.
If you can get in Download mode, then start Odin and flash a TWRP Odin flashable recovery:

Then at least you should have a functional recovery. From there you could either try to flash your stock ROM again, or any another ROM.
Are you 100% sure what you flashed was a good stock ROM for the T989 ?
Dont you have a nandroid you could restore?

[Q] Completely lost. trying to update from 4.2.2 to 4.4

im sorry if this has been asked before. i was very hesitant to post but ive been trying to resolve this issue for 2 days and browsing and reading as much as i can with minimal results. i am trying to update to 4.4 from 4.2.2. i initially had a hard brick but was able to restore life with the img file but am stuck there. it boots into paranoidkangdroid sometimes (which is the rom i used before it hard bricked but not the one on the img file i created...weird i think). i think the more reading i do the more confused i get. im not sure if i have to flash to stock to get the ota, or whether i can just flash a 4.4 rom. im not sure what other information i should provide. thanks for any help and again, sorry if this is inappropriate.
Does your phone boot into download mode? If it does, flash a custom recovery and custom ROM to at least get your phone into a working state.

what steps do i have to take now to update to 4.4 and flash a custom rom?
do i first need to flash a 4.4 bootloader?
Personally, I prefer cwm over twrp.
Just copy a custom ROM to your external SD card, boot into recovery, wipe cache, dalvik, data, system, install ROM, reboot.
Depending on the ROM you install, you may have to update your bootloader and modem.

[Q] Urgent Help! Bricked Samsung Galaxy Tab 3 10in

Hello all i have bricked my Samsung Galaxy tab 3
I have tried rooting but it ended up giving me a boot loop
Nothing has worked, I have tried flashing a stock ROM, it was unsuccessful, i have tried a rooted ROM, it was successful though i was still stuck in a boot loop, so i flashed Philz recovery and that worked but it didn't clear anything.
I'm currently downloading another Stock ROM and I hope it works.
I also tried adb and that didnt work either.
How can I stock recover this device.

Have you tried using Odin to return to stock? don't forget to "uncheck" auto reboot. After flash completes, shut down, then restart.
Here's a thread for using Odin to return to stock
...and wipe/format system, data, cache etc before flashing
Which version? P5220(the LTE version) P5210(wifi only version) p5200 3g version
you can try out odin, flash everything including stock rom and recovery. Start everything all over.

Do you use download mode to connect in odin? Try different USB cable, PC or even Odin ver.

SM-P600 Stuck at Samsung boot screen

My tab was running stock 5.1.1 rooted and twrp
I flashed the cm-12.1-20160501-NIGHTLY-lt03wifi to check it out, and it was giving me issues so I booted it up in download mode and reflashed P600UEUCNI1_P600XARCNI1_HOME.tar.md5
and now its just sitting at the samsung loading screen .
I cant seem to get it into any type of recovery mode, only download mode.
anyone have any ideas on what i can try to do to get it booting again?
Ok correction i am able to boot into recovery mode.
Ok i was able to get into recovery mode finally..
I reflashed the cm12.1 zip and that is booting.. but still having issues ... it rebooted after doing the initial setup..
I would love to get back to a stock type rom...
You're gonna need to boot into recovery and wipe data & cache.

I was able to get it booting CM again, but i really would like to go back to the stock rom, but flashing it via odin doesnt seem to work, that when i get stuck at the sumsung screen..
now i was thinking this might be because twrp is still the recovery and not the stock. so i need to find the stock recovery to put back and try that i guess
If you're flashing stock firmware, it should replace TWRP with stock recovery.
You're also going to need to wipe data & cache almost any time you are switching ROMs (and definitely if you are switching between stock & CM).

Thats what i thought too about the recovery.img
so you think i should wipe data/cache in trwp then reboot it back to download mode and flash via odin?
