[Q] Need to return to stock - Sprint LG Optimus G

I'll be putting my Optimus G up for sale soon so I need to wipe it and return it to stock. I currently have CM 11.0 official ROM installed but I do have a backup of my stock rooted ROM. Do I need to reflash the stock ROM and do a factory reset to remove the CM11.0? Or is there more that needs to be done?

I would suggest flashing the stock ZVC rooted ROM and wiping the sd card as well as a wiping data. You should be able to do both from recovery. That would be the easiest way. Here is the link http://forum.xda-developers.com/showthread.php?t=2536636
You can also flash the full .bin from LGNPST. Follow this thread, it will be a COMPLETE wipe and reset everything even recovery as far as I know. This is the thread for that. (it would be what you would want to do to turn in to the manufacturer)

Noyou cant restore your stock rom via cwm. You need a zip file of the stock rom that came with you phone.. Its not compulsory that you should always be on stock to flash another ROM. factory reset wipe and flash..
but i did backup my stock rom via CWM before flashing the custom rom.
all i just want it that when i move to stock rom. i dont want to lose my root access and cwm.
if i flash stock rom ftf root access and cwm will gone right?

As long as you backed up while you were rooted and had cwm i think that they will be there but if they aren't its not a big deal to re-do them.
If you flash the ftf they will be gone.
you can flash hellcat rom over cm11 without flashing stock rom

I have done it before. Follow these steps.
1. Goto CWM and wipe user data and cache. Also wipe dalvik cache.
2. goto "mounts and storage" and format system, data, cache.
3. Now install your hellcat rom from SD card. Also flash GAPPS and reboot.
Thats it.

[Q] How can I go back to stock recovery and rom?

So I just bought this phone from tmobile and rooted it and flashed TWRP. Everything worked fine when I booted it with root access and everything. it started a bootloop after I tried to backup to external SD upon first reboot.
Is there anyway to revert back to pure stock? That means stock firmware (4.3) and stock recovery . So basically , I want it to be the same as I bought it.

Sure, that's easy...
Just go to http://SamMobile.com or other trusted source and download
The Tmobile official stock NE1 Kitkat 4.4.2 firmware and flash it using
Odin.
Make sure you do a full wipe in recovery mode before odin flashing the
official stock firmware.
(wipe data, cache, dalvik cache, system and do a factory reset in recovery.)
Once you have done that successfully your phone will be official stock.
Good luck!
Thanks my man [emoji106]

CM11 AOSP to Stock rom??

I originally was on ZVC build then after much hassle I managed to get CM11 working after going back to jellybean 10.2.. So what I want to do is upgrade to 2-faced ROM or Optimus DE, any suggestions or help? I am currently recieving a bootloop when I try to flash 2-Faced after full wipe, dalvik and cache, installs fine but bootloops out. Not sure what steps to take besides the final alternative which would be to .tot back to stock and reflash from there.

Help. Bricked(?) t999l

Hi,
I don't know what happened because I didn't do anything out of ordinary, but my S3 (TMO LTE) seems bricked. It was unlocked, rooted, and was running pacman lollipop ROM. The recovery was TWRP (the latest). I was going to sell this phone, so I turned off, removed sim card and microsd card. Powered it on. Everything was working. Then, I went to setting and hit factory reset from there. The phone restarted, but got stuck on the blue teamwin screen (the one that gets displayed before TWRP loads). The phone can't get past it. Not sure what caused it because it was a simple factory reset from the OS itself. Any help would be appreciated.
Thank you,
Just flash stock rom from sammobile.com using Odin. After flashing, boot to recovery and perform a full wipe.

If I flash the firmware from there, I'm going to lose root, right?
The phone will go back to completely stock, no root.

Is there an alternative fix that will maintain the root TWRP? I know I can just root it again, but if possible I'd rather not go through all that because I am relocating in 3 days.
Do you want to sell the phone with a custom ROM? If you do, you could download and flash another custom ROM after re-installing TWRP.

Yes. I'm trying to make it more appealing with Lollipop on it lol So, just to double check, I should just install TWRP using Odin then install custom ROM, correct? By the way, do you have any idea what why my S3 got bricked? Did I do something wrong???
Sometimes, things just happen. Could be a several factors, one of which is the fact that cm12.1 may not have reached a stable state on the device. Also, the latest bootloader for the T999L is 4.3 while KK is the latest for T999v. Maybe the KK bootloader makes the phone more stable? I really don't know.
Yes, just flash TWRP, boot to recovery, do a full wipe of the system, cache, dalvik, data, flash ROM, flash Gapps, flash supersu if the ROM is not pre-rooted, and re-boot.

[Q] Wanting to do a factory reset on a rooted and bumped VS985

Hey everyone. My phone has been running like crap lately and I have thought about doing a factory reset. I just had a few questions. If I did a factory reset I'm pretty sure I lose root, but what about the custom recovery?
Also, this is what I had in mind to do - but would you mind checking to see if it would be my best route please? I am going to install a custom rom on it. But just wanted to do a factory reset / install stock firmware first before I did it.
Download and install stock firmware. 10B I believe is what it is.
Root it again and put the bumped recovery back on it.
Install CM12 or another rom.
Is that pretty much what I should do?
Thanks!

If you do a factory reset (with the kdz tool, its the best way if you want to reinstall the stock firmware), you lose everything (root, recovery, etc..) because it will flash the phone completely.
I recommend you to take a look at this for all the thing that you need to do: http://forum.xda-developers.com/showthread.php?t=2785089
And make sure you never do a factory reset from within Android w/ a custom recovery like TWRP installed, otherwise your phone will end up in a continuous boot loop. There's no reason for you to go back to stock anyway, as you're planning on reinstalling CM12 or installing a different ROM. You'll be doing a factory reset (wiping System, Data, Cache, and Dalvik) from within TWRP before flashing anyway, so there's no need to go back to stock beforehand.

If you flash your phone with kdz, yes, like the guy above said you will lose both root and recovery. What I'm curious about is reason you want to do it? You already have custom recovery so if you want to do factory reset (that is wiping data and cache partitions) why not do it manually there?
And what is the point of it? As you said you will flash CM12 or another ROM, so that will basically do a factory reset, you will wipe all (system, data, cache) to install your new ROM...
Of course before flashing or wiping system partition with TWRP I recommend doing a backup just in case.
Thanks for the info everyone. The reason I wanted to do a clean factory install instead of just putting on CM12 is because if I didn't like it, I could just go back to a stock, rooted KK.
Like I said it has been acting up lately, so maybe a clean install of factory can help it. That way, if I don't like CM I can just restore my clean copy.
Where as now, if I didn't like CM I would have to restore my messed up backup.
But I will probably flash back to stock firmware, root it again and put a custom recovery on it again. Make a backup of that, then play around with some ROMS.
But once again, I appreciate the help!
