SNP bricked?

[Grimgrak]

So i tried to downgrade my rooted snp12.2 from lollipop to kitkat which resulted in it freezing at the samsung screen. I then went into odin and loaded up the chainfireautoroot but now i'm still stuck in the samsung screen on boot up!!!! What should I do next?

Guess it didn't like that version of kitkat as installing the newest lollipop allowed it to boot up again... I wonder if i have to somehow get rid of lollipop before installing kitkat?

I'm kinda thinking that its a bootloader issue . . but i'm not sure how to advise you. Best to ask on XDA but even there it's hit and miss since there isn't much activity there either.

You need the bootloader, what version of Kitkat you are using ? Kitkat 4.4.2 NK1 ?
Before released the Lollipop OH2, many had problem with the OF4 ( bluetooth keyboard not working ), and they did flash back the Kitkat NK1.
You can flash any version , any region, as long as you have the right bootloader and firmware.

Happened to me and this is what I did:
Go to recovery mode. Power+volume up key.
Scroll down and wipe cache
then factory recover
then reboot.
It may take some time to reload apps but be patient. I had to restart twice and it's been fine ever since. Took about twenty minutes to sort itself

I am trying to install the last version of kitkat but again it seems to be stuck.
P900UEU1BNI2_P900XAC1BNI2_XAC and P900UEU1ANC5_P900XAC1AND1_XAC
Even after doing your wipe cache.
Only thing that loads is P900UEU1COI1_P900XAC1COI1_XAC

The latest version for US is NK1, XAR is product code for US region
Download firmware: P900UEU1BNK1_P900XAR1BNK1_XAR - SamMobile
Load Bootloader, AP, and CSC in Odin, you should not have any problem
Here is BL, CSC for P900
SM-P900



I have flashed over 100 times and never have any issue of boot loop.

Why do you have one file with BL CSC and AP loaded? I only load AP...... when flashing lollipop and it seems to work...
Maybe thats the extra step my kitkat needs.

I see many having a hang at Samsung logo when flashing back to Kitkat without Bootloader.
It's up to you as I only try to help.
