Need help in flashing CM 10.2

I recently got a nexus 7 2012. I unlocked it and installed the custom recovery (CWM) according to the guides given in the forum and elsewhere. The problem comes when I install a custom ROM like CM10.2, It installs fine, but the boot does not resume after the CM animation. I tried another rom like AOKP and even TWRP as recovery, still the problem persists. My bootloader is 4.23 and flashing back to stock ROM works as normal. Please help.

What recovery you use. And what tool you use to root. For I use WUG toolkit. And install TWRP. And install CM 10.2 with no problem. Maybe you not really root. Update your superuser before that

Stupid question: are you sure you are flashing grouper ROMs?

Tried a lot of combinations with ROMs and recoveries finally I solved it. CWM wasn't working with its wipe options and tried TWRP and gave the full wipe of all partitions before flashing CM and gapps and it worked!!!!

Downgrade kitkat

I searched the whole forum and couldn't find an answer.... I flashed the new KitKat official ROM with the radio and everything is working perfectly but I miss all the features I had on 4.3.1. So I tried to restore the backup I did before flashing and it stays stuck on the Google logo..... What did I do wrong or am I missing something?

Maybe you didn't do a factory reset to clear the cache. What method did you use to update to 4.4 and what method are you using to restore 4.3?

restore via twrp and flashed 4.4 by wiping everything and flashed the 4.4 update zip with the 0.97 radio

you can delete thread now, i flashed the 27-84 radio and now everything is back to normal booted up to my recent rom thanx

[Q] Downgrade to CM10.2 from CM11

I tried CM11 for a few days. But since pie control is a crap in CM11 I tried to revert to CM10.2
I flashed the JWR66Y bootloader (z20) and radio (.84), then then cm10.2 and the 4.3 gapps.
But after reboot I get a FC (com.android.process.acore stopped) and then a bootloop.
I googled and found out, that this may depend on the way, a newer version stores the contacts. I flashed back to CM11 (working), stopped syncing, deleted the contacts and tried to flash CM10.2 again - same result.
So - is there a way to go back to 10.2?

I did, flashed radio & bootloader via sideload, then flash rom and gapps from recovery

I flashed radio and bootloader via fastboot, rom via recovery and gapps via sideload. Is there a difference between flashing via sideload and fastboot?
Will try your way tomorrow.

Might be easier just to flash the 4.3 factory image, flash recovery, root and then cm10.2? That way everything gets wiped cleanly.

Wiping cleanly is exactly the point I try to avoid.

I'd like to hear if your successful downgrading without a clean wipe. Let us know.

Can't flash anything TWRP: FAILED

Trying to install CM11 on Note 3 international Qualcomm. Rooted with CF-Autoroot, flashed TWRP with Recovery Tools and then booted into recovery and wiped everything and installed CM11 nightly from SDCARD. It came up as 'FAILED'.
I did a backup but internal storage is not showing up and I wiped it afterwards. I have backed up original recovery.
I also tried flashing a previously nightly with no luck. Also tried flashing this: [OnLine][07.02.2014] X-NOTE build 9.0 N9005 NA7 4.4.2 - flashes successfully but does not boot from samsung splash screen.
I was on stock 4.3 prior to doing any rooting etc..
How do I get back to stock 4.3 or successfully install 4.3?
Thanks in advance.

Can't get back to 4.3 once you've upgraded your boot loader - which it appears you have done with x note 9. look at the TWRP thread and get the version for KK and it should work.
If by some reason your BL hasn't upgraded, then just flash a 4.3 rom.

failing CM11 install

so decided to update my N4 from 4.3.1 to 4.4? from 10.2.1 stable to 11 nightly.. booted into TWRP, and tried installing CM11, but FAILED. wiped Cache, Dalvik Cache, and Factory Reset. Still FAILED. Wiped System too. Still Failing. Any ideas?
The CM 10.2.1 zip doesnt work either. Originally i had updated to 10.2.1 and noticed it was still android 4.3.1 XD just.. updated? so decided to go CM 11 then this happened T_T
any ideas?
-----------------------
so i found out CM11 doesnt work with TWRP. had to use ADB to flash recovery to CWM then flash CM11....

Sounds like you need to update your recovery

Happened to me also, you need to update to the latest version. I have CWM but for TWRP is probably the same.

yeah o well. i flashed to CWM recovery (newest one prob) and it worked. running CM11 now.
