Coming from factory image 4.3 rooted, if i want to revert back to 4.2.2 , will there be issues? Thanks!
Using 4.3 bootloader n radio on 4.2.2 won't cause any issues. At least I haven't had any trouble.

I've seen quite a bit about updating boot loader and radio before v flashing 4.2.2, but what about the other way around? Do i have to flash 4.2.1 boot loader and radio or am i good? Thanks in advance

Before rooting i did the ota to 4.2.2. In all the threads it says if you haven't done the ota you need to flash 4.2.2 bootloader and radio before flashing 4.2.2 roms. So if i wanted to flash a 4.2.1 rom coming from a 4.2.2 rom, do i have to flash the 4.2.1 bootloader and radio or will it work with the 4.2.2 radio and bootloader? Hope this clarifies. And thank you

OK, that's clear. Sorry for my English
First, I used to update to 4.2.2 without updating my bootloader, I just updated my baseband because the Microphone and the Earpiece didn't wok without it (at least, that was my situation).
Second. I dont understand why you rollback to 4.2.1, but if you want to, just keep the 4.2.2 bootloader and baseband. That's OK. Hopefully.

I just want to try out some ROMs that haven't been updated to 4.2.2 yet, like raspbean jelly or baked black bean, but i can't find info on if you have to flash the baseband and boot loader with it

Currently on a 4.2.2 custom kernel and rom. I was wondering if I actually had to go through the hassle of relocking and flashing the stock 4.3 image or can I just flash the radio and bootloader on their own and then flash one of the pre-rooted 4.3 roms?
Is there anything in the stock image besides the radio and bootloader that won't be found in one of the 4.3 roms that are being released?
You technically don't even need to update your boot loader or radio. I used the 4.3 leak just by flashing the rooted ROM. When the official 4.3 was released, I just flashed the new boot loader and radio in recovery and flashed the ROM. No problem.

I guess there is no need for relocking your phone!
You can flash the leaked rooted ROM version.. Just look in development forum!

Hi. I'm running a nexus 4 at 4.3 jellybean. I want to update to 4.4 kitkat. My device is rooted and I'm afraid if I do an OTA I might brick my device. How do I update my rooted nexus 4. Thanks.
Are you using stock or custom ROM?

Im assuming that you are on JWR66Y build number. If that is true download this and flash via recovery.
Flashing 4.4
I have a Nexus 4 on 4.3, JWR66Y running Purity build 8/26/13.
I'm wondering which file I should use to flash the new 4.4 to my phone. I thought I was suppose to use a factory image to flash fresh into a new google image, but each time I used SkipSoft Toolkit, it never was able to flash the system.img. It would say 'error: cannot load system.img' or something and the entire flashing process would end ubruptly.
Am I not flashing the right image? Should I go to stock then do the OTA update? What do you suggest as I'm not very skilled in teh nexus hacking :cyclops:
Hello guys,
i have a question, Can i change my phone to a previous version?
Now, Im in 4.4, and i want 4.3 JWR66 on my nexus. Could be a problem if i flash a previous version?
Thanks.
As far as I'm aware it should be fine, I flashed KitKat and then decided to flash back to 4.3 which worked fine, now I'm back on 4.4 with no issues. Just make sure you backup incase it doesn't work for you!

if you are rooted and have a recovery you can flash a 4.3 ROM...Also make sure you have .84 Radio..If you have have .97 Radio, flash .84 radio after flashing the ROM and the GAPPS..Here is the link for .84 Radio...
P.S. Post a question in the Q&A section
Thanks!
Hi xda people I have a problem I dropped nexus 4 about 6 months ago and sold to workm8 which he fixed himself for 90quid. Anyway he ota updated to 4.3 fine it was locked and unrooted then he got bootloop in 4.4.2 ota update so I had a look for him. I was able to use wugs toolkit and stock to unroot to 4.2.2 which works then I tried locking bootloader and ota to 4.3 which bootlooped. I also try to revert ro stock and unlock to 4.4.2 but same any ideas? Out of ideas im guessing maybe nand block is not writable maybe? I did drop 3 ft. I googled but only found issues with nexus 7 ota

Did you wipe after you flashed the KitKat factory images?
Does the phone display the proper baseband and imei?
Edit I tried to wipe data and cache thru stock recovery after ota update to 4.4.2 still not 100% from wugs
Not sure I presume I did. I definetly did wipe before going to kitkat by booting custom recovery from wugs and then reverting to stock 4.2.2 I only tried ota update from there. I think when I then tried 4.4.2 same way that 4.2.2 worked I may not of. Guess ill try again at some point but he just wanted to play with new toy so I just put on 4.2.2 for now.
So is the ota flaky as I thought all data would be kept anyway. Thanks for advic3
Imei and baseband show on bootloader but not on hand at mo so dont know baseband it on.
I also tried sideloading stock rooted 4.4.2 zip but same bootloop and sure I wiped after and tried again may be 2rong getting confused I tried for few hours lol

Dunno if it's part of the problem, but remember flashing different versions, make sure that you are using the correct radio.
You can find the IMEI and Baseband in Settings>About phone
