A few questions to ROM updates - Nexus 4 Q&A, Help & Troubleshooting

I currently have 4.2.1 rooted with TWRP. I use franco's kernel and now wondered if I can simply update via OTA? From what I read it is possible with TWRP ?
If that is not possible, should I just download the 4.2.2 update from google and flash it with TWRP ? What is the deodoxed 4.2.2 download?
Thanks

Read this thread http://forum.xda-developers.com/showthread.php?t=2145848 you can find there all answers

So as I have:
root
franco's kernel
TWRP/CWM
Unlocked bootloader
the only way for me to get 4.2.2 is by flashing it via TWRP/CWM ? Will this just update my system or install a new 4.2.2 meaning all my homescreens/Settings/.. are gone ?

first of all you must flash system.img and boot.img to have stock system, after that you can flash update via TWRP/CWM and reroot. That not wipe your data

and where do I get the the boot.img system.img ?
and i push that to my phone via adb/fastboot ?

In need of assistance with 4.3 root

Hey there, I've recently made the purchase of a samsung galaxy S4 1337m
Once i got it home, the first thing i did was root it via Chainfires Root, and downloaded
rom manager, and installed CWM, and backed up my original OS with the original root
to a SD Card, once i did that I installed Odexed Andriod 4.3 for US and CAN, when i discovered
there was Chainsfire root guide for this version in particular, i tried to install it, what i did was attempt
to flash the latest root onto 4.3 via oden, after which i would flash the modded software to work for 4.3
however, in the process i ended up losing CWM, and the root all together, so i was wondering if anyone
was willing to lend me a hand getting the root onto my 4.3, so i can get my CWM back on.
Thanks!

I haven't used 4.3 but from what I've read I believe you just flash the .zip chainfire provided from recovery.
So now you will have to ODIN back to stock if you lost your recovery, re-root, install recovery (recommend TWRP instead), re-flash 4.3, flash the .zip provided from chainfire in his post here:

Do you know whether or not I'm able to re-flash with oden using the recovery created by CWM?
Or do i need to download the stock rom for my phone, which i imagine I would do a factory wipe
then boot into download mode then flash the stock rom?

The backup created from CWM should be a .zip that is flash-able only from recovery afaik. You will need your stock firmware .tar file and flash with ODIN. This is only if you surely cannot boot into recovery. If you manage to boot to CWM you can flash your backup of course.
Your STOCK firmware can be downloaded here:

I currently did a factory wipe on my device, and flashed using odin with my stock
rom, things are looking good thus far, will keep posted if anything goes not as planned!

Restore stock recovery

Hi Guys,
So I'd rooted the Nexus 4 by unlocking the bootloader and flashing the rooted kernel. I didn't flash a custom ROM after that. So what I had was a 4.2.2 Stock ROM with a rooted kernel so I could use the root functions. Now I get a system update notification after it downloads the new stock 4.3 on its own on my phone. But now since I don't have the stock recovery, selecting " Reboot and install update" after the system update downloads just leads me to the CWM recovery and obviously I don't have a custom update.zip to flash.
So my question is..How do I flash back the stock recovery and hence lose root and update to 4.3 without flashing the STOCK ROM back, thereby keeping my existing apps on 4.2.2. intact? So what I wanna do is flash the stock kernel which restores the stock recovery...Let the stock system update itself to 4.3 and then maybe Root the phone again..
Could someone kindly direct me to a solution?
Would appreciate a quick response
Cheers!
There's no way to restore to stock without wiping everything

Download the factory images, you can find stock recovery inside. Flash the recovery.img in bootloader mode.
Code:
fastboot flash recovery recovery.img
Kernel and recovery is 2 separated partition in Nexus 4, so flashing kernel won't restore your recovery.

[Q] JWR66Y update

Hello -
I have the original Nexus 7 and was wanting to update to the new JWR66Y release. I am on a stock rooted rom at the moment. Can I just flash a rooted version of this update? And where can I find a recommended rom?
I tried to flash that grouper.zip via TWRP but it fails when I try and flash it. Am I suppoded to try and OTA update, then flash the grouper.zip?
Thanks in advance for you help!!
What was the error? I had to replace the 'debuggerd' file and then flash the grouper.zip in twrp recovery. Then flashed the supersu 1.51 zip to get root back.

To flash a flashable .zip file you need a Custom Recovery like TWRP. So,
1. Root your phone with IORoot25. - This will give you root.
2. Download and run AutoRec on your phone. - This will downgrade your bootloader to JB and install TWRP.
3. Boot into Recovery Mode (TWRP) and flash your modem.zip. - This will give you a new modem.
Remember to back up your modem before flashing a new one.
Thank you so much.

How do I backup the stock recovery for Note 3 SM 9005?

If I install custom recovery (via odin) my stock recovery will be gone right. So, how do I backup my current stock recovery.img so that I can recover it later? I was looking for the answer on many threads and most xda members suggest to use the 'fastboot' method (which temporarily injected the custom recovery and return the stock recovery immediately). But this fastboot method does not work with Samsung Galaxy Note 3 SM-9005. Is there any other alternative how to backup the stock recovery?
EDIT: the alternative method that I can think of is to use Flashify app. It can backup the stock recovery image but, in other to use this app, I must be root. and in other to root i must install custom recovery.. and.... yeah I lost the stock recovery.. this is the problem.
Reflash the official rom

Hmmm.. here is my situation. I have the official ROM KitKat. It contains the kitkat stock recovery.img. I updated my phone to Lollipop and I believe it has updated my recovery.img to lollipop version (I found it has more options than the KitKat version). I cannot find the official ROM of my phone. My question is,
where can I find the official lollipop ROM? I just received it via OTA. Does reflashing the ROM will backup my recovery.img? I mean I want to obtain this recovery.img file.
Android System Recovery <3e>: LRX21V.N9005DXUGBOD1
