[Q] Downgrade to CM10.2 from CM11 - Nexus 4 Q&A, Help & Troubleshooting

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.

[Q][HELP] Lost signal on 4.3 after reverting to 4.2.2

Hey,
Today in between flashing a new ROM i went back to 4.2.2 cm10.1.2, just to check some things out before flashing a 4.3 ROM that i was intending to do in the first place.
However after having reverted to 4.2.2 when i went and install the 4.3 ROM i noticed i had no signal, since then i've tried flashing the radio and boot from 4.3 Factory Image via fastboot, tried installing a different 4.3 ROM, all with no success.
What can I do?
Btw i still get signal in 4.2.2
Thanks.

Check APN settings?
How do I do that?
Also the phone app just crashes totally when I try to do anything with it, even entering airplane mode triggers that.

You should do a clean wipe before you flash 4.3 from an older version, do a factory reset and wipe the system partition, then flash 4.3 rom.
via xda app
It might have to do with TWRP.
http://forum.xda-developers.com/showthread.php?p=45323439
Try flashing TWRP 2.6.0.0 then proceed from there to flash your rom.
I guess i forgot to mention, i did a clean install, i factory reset before reverting.
And i have TWRP installed, I've tried several ROMs and in all of 4.3 ROMs i dont have signal and the Phone app FCs when i try to use it.
On that note, does TWRP Factory Reset wipes System Partition?
Factory reset does wipe system partition except /data/media.
Flash TWRP 2.6.0.0 (this version)
Factory reset
Flash Rom
Flash Gapps
Flash Modem
Flash Kernel
Flash Supersu
Wipe caches
Reboot
Btw, here is some insight on what to wipe in TWRP:

Oh I just saw your previous post, didn't understand it at first but now that I think about it I do actually have 2.6.1.0.
Ill try what you said and report back.
Thanks.

Nexus 4 stuck on boot animation

Guys I know there are a ton of threads with this problem but no matter what I try, i'm still stuck on a boot loop.
So basically I had PA Rom 3.99 RC2 on my nexus and everything was fine. I then tried to flash PA AOSP kit kat build
but my phone would not boot so I went with a factory image occam 4.3 Phone booted and all was good. I was liking the
stock experience and then about 4 days later after a reboot, phone got stuck on the boot animation X. It would not get out of it
so I decided to flash PA Rom 3.99 rc2 again via ADB push zip. factory reset, installed the rom and gapps, wiped caches and thought i was good to go. Well the phone again would not get past the boot animation of PA.
i then decided to go with the Factory image occam 4.3 via fastboot and installed it and everything. Again stuck on the X. So then I tried PSX rom 4.3 again via adb push, did my factory reset and flashed the rom and gapps and superSu. Also got stuck on the boot animation. Left it for over 2 hours bootlooping and nothing.
Going crazy I went and fastboot the 4.2.2 JDQ39 img and downgraded bootloader, baseband. Installed it and again, stuck on the X animation. just hangs there.
Any help? i don't know what else to try, currently using my HD2 and it is sooo slow :cyclops:
Make sure to use latest cwm recovery. Avoid using twrp recovery. Use the toolkit and flash stock image. It will wipe everything in the phone but it will fix it.

Thanks for the suggestion but still nothing. Updated CWMR to 6.0.4.3 and tried the 4.3 stock image. Still hangs on bootup. android file transfer recognizes the device is plugged in via usb but just gives me the error "could not connect to device"
Oh man I don't know what's wrong with my nexus

I'm having this same issue, and it happened just like you. I flashed CM 10.2 nightly 20131114 this morning and I tested it to make sure everything was working. I decided to reboot the phone, and after that I keep getting stuck at the boot animation no matter what I did. To no avail, I reflashed a working zip, restored a backup, restored another backup, flashed the 4.4 factory image (wiping the entire phone), the 4.3 factory image, and then I read that the 4.2 baseband can fix it, so I flashed the 4.2 factory image. That 4.2 image gets it to boot, but without baseband. Right now I'm trying different radios just to see if I can get service again. If it matters, I was running the hybrid 33/84 radio for T-Mobile's LTE when this happened. Very, very peculiar situation here. I've never had anything like this happen, and especially remain an issue after wiping the entire device. I'm hoping it's not a sudden hardware issue.

just re-flash 4.2, it'll work. I've been doing that since Monday. but I want kitkat too!!
my device is stuck on the boot animation too. is there a way to reinstall the default 4.3 recovery and just rerun the update or something basic like that? my device was almost at stock before running the update. the only two things: twrp and rooted via recovery. so i thought everything will work fine and now there is no backup...

Why?
Just fastboot flash all the image files (boot.img,recovery.img....) from the factory image.

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?
sent from xda premium app
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

crDroid 4.4 wont flash Nexus 4

Hi Folks!
I have problem flashing crDroid 4.4 (http://forum.xda-developers.com/showthread.php?t=2516316)
I am currently running stock 4.3 rooted android, and i have TWRP.
I tryed to flash crDroid and it fails, i cant remember exact error (cant find logfile for TWRP also).
I copyed crDroid and gApps files to !ReadyToFlash! directory, booted into recovery, wiped to factory setting, and then tryed to flash crDroid...FAILED.
How should i do this properly?
I have one wild guess, but not sure if this is true.
Maybe i need stock 4.4 on my phone before i can flash crDroid rom?
Regards
Rodney

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.
