How to return to stock recovery? - LG Optimus G Pro

hi,
E980 ATT. Installed CWM 6.0.4.8. How do I return to stock recovery?
Do I need to erase all data on the phone in the process of returning to stock recovery or is there a way to just flash the recovery?
Thanks

I tried to restore my backups in FreeGee but it didn't work. I had to use a tot to get it back. I recommend the KitKat tot. It worked perfect for me. Fully restored, but you will loose everything.

Recovering from bootloop

Hi, I was wondering what people do when they enter into a bootloop. I kinda want to find a easy way to recover from it. Atm I have to re-root my phone again using the r6 madaco method.
So the question is there a better way to recover from this. Like should I flash a custom recovery? I think there one from unrevoked if memory serves me right.
Thanks!
How about restoring nandroid backup and trying to the activity you want to do again..

Any one of these should sort out that problem.
Nandroid restore
Wipe data
Flash rom again
Flash a different rom
I think what I should do is flash a perma custom recovery image. I tried using unrevoked yesterday but it seems to have failed during the root.

4.4.2 CarbonRom- Lost IMEI/Signal after flashing latest nightly

As title states, i lost my IMEI/carrier signal after flashing the latest nightly (2-27), and haven't been able to get it back
I tried to inject my imei backup, but using the *#7482# to enter qualcomm usb settings hasn't worked, not sure why (maybe it was changed in kk?)
I tried flashing a modem, but i can't find the appropriate kitkat one for my phone. the only one i found was for jellybean.
Any ideas guys?
I can't seem to get any dialer codes to work
If you are on ATT Flash d2att instead of d2lte

There is no KK modem because there is no official KK ROM.
Try flashing the latest AT&T modem.
If flashing modem doesnt work. You need to restore back to stock then make sure everything works. Reboot back to recovery and do a backup of your rom and EFS. I use Philz recovery. After you make ur back up go ahead and flash custom rom.
If you did backup your EFS in recovery. Just reboot back to recovery and just restore only the EFS. Save you from reflashing back to stock.

flash back to stock recovery for ZVC update?

im stock rom zva, rooted, cwm recovery
can i flash stock recovery without loosing all my data?
or does that mean i have to flash a total stock image and go back to like when it came out of the box?
i dont mind loosing root for a while with the new update, and i know you can update with the other recovery. i just went with cwm cuz im used to it from every other phone ive had
any help would be great.
thanks!

You would have to flash stock recovery and unroot, but it is always recommended to do a factory reset after an OTA update anyway, as you may experience issues. The easiest way is to make a backup with titanium and copy all necessary files to your PC, then flash the ZVC tot using LG flash tools. Root after this with ioroot25 and restore your files and data with TBU. Keep that backup on your PC as you never know when you'll need it. You'll have a reliable update this way and minimize or eliminate any update problems.

It does, sms/mms will be in yellow and there are 2 options, select the one that says XML and you will be in business when you restore them.
Edit: By 2 options, I mean don't confuse it with "Messaging" app. Been there done that.

Need Generic Nandroid Backup, Or other solution?

could someone post a file of their nandroid backup of the stock rom? flashable thru twrp please.
I tried flashing the OTA on a stock rooted rom with twrp installed and my phone didn't like that. (rookie mistake:silly now any restore, rom flash, wipe, ect . will not work and my phone boots straight into TWRP every time. So if you could give me your nandroid backup w/o any data, or if you have a better solution please give me that. thanks!

We need more details really.
But if you can get into recovery, have you tried a factory reset? Then reboot.
We need to know your TWRP version, (KK or not), What ROM you were on prior, and what ROM's have you flashed since.
Virtually Nothing Works

I was on the latest snapshot of CM11 and then i flashed LS970ZV9_DEODEX_STOCKROOT_1_13.zip
then i got the normal notification for the available OTA update (ZV9>>ZVB i believe) and i forgot that OTA's and custom recoveries don't work well together.
So I've literally wiped everything except for sd/data/media (or what ever holds all your photos and music ect) and I've tried restoring ALL my backups, nandroid wont ever work...
I believe installing a new recovery MIGHT work although I've tried two different versions of TWRP i had on my phone. (current TWRP v2.6.3.0)
Requesting:
1. Someone's NANDROID backup zip file with no data, obviously
2. CWM recovery for LS970 (lg optimus g) sprint
3. Drivers for XP PC to be able to access file system of my Optimus G

If you are on a stock rom you should be able to use freegee through the play store and it can install CWM if that's what you want.
Have you tried reflashing a stock rom? Why did you flash the zv9 when the zvc is available? I would try flashing that in recovery, twrp should flash it.
There are a few other options as well. Check the brick recovery thread and it will lead you to a teeny bin, you can use the programs that are suggested there and it will flash a recovery and unlock.

I think you can also use fastboot to flash a different recovery and unlock.

Yeah i tried reflashing all the roms i have on my phone and i tried the ZVB/C stock (deodexed) rom and they both failed flashing.
ZV9 was the only success until i tried that OTA. I'm downloading the CWM recovery zip file right now to flash in TWRP. could you tell me how i could move that file to my phone within TWRP? I have trouble finding out how to access the file system from my computer when my phone is in TWRP
Thanks for the quick replies!:good:

That's what we needed to know.
I think the issue is your modem. ZV9 is for ICS. ZVB/C is for JB/CM/AOSP
So if you still have your recovery or any unlocked recovery, flash the ZVC modem from the teeny bin thread. Then I would suggest a Stockish Rom. That should get you going.

Restore stock recovery without losing data

Hi. It's been a while since I've done any flashing etc so not exactly sure about this. Is there a way to flash stock recovery without data loss?
I restored my s3 to stock before giving it to my niece but didn't realize twrp was still on there. I guess the phone is trying to get an ota update and ends up in twrp when restarting.

I think it has what you need.
And for those who prefer, a link to a stock recovery that is flashable from a custom recovery can be found in this thread by enewman17.
