Hard Factory Reset equivalent using TWRP - LG Optimus G Pro

How do I do the equivalent of a hard factory reset using TWRP on my LG Optimus Pro E980?
I want my phone to be restored the the way it was when I purchased the phone . I want TWRP to be gone and to have the stock unrooted version of software with updates that would have been on my phone if I hadn't rooted or added TWRP.
TY!

back to stock help

So I have flashed some customer roms and then used odin to go back to stock after failing to restore a back-up using TWRP. After using Odin and the latest factory image from XDA. I am still showing signs of old flashes. I would like restore the phone completely back to factory. I am not sure if I need to reformat something using twrp. Can anyone help with some advice?

If you need to send it back, you need to:
wipe data/factory reset
reset flash counter (requires root, triangle away)
odin stock rom
The root toolkit in original development forums can babysit you through the whole process

Elaborate on what u mean by signs of old flashes
Odin should put back stock, u will keep storage and sd untouched
If you flashed a 4.2.2 aokp cm10 rom I think it screws up nandroid restore folder, it redirects restores to data folder...
I lost my backup too
Chain fire app has root away script use that to remove any sings of flashing

I infact had flashed AOKP. I was seeing signs of it left behind even after using odin to go back to stock. This is not my first Sammy device and havne't run into this issue before. I will try wiping things down multiple times. I think the thing that maybe bothers me the most was after going back to a factory image the last time Samsung Kies would not even check for updates saying " your devices current firmware is not supported to update from kies"
This is new as I have had my Note 2 rooted w/ custom recovery since it came out and had been able to update using kies in the past, just wasn't able to use the OTA updates from the device. (which I knew from the past)
Anyways I hope the clearing multiple times data/system/cache clears it up after another Odin flashing

[Q] going back to a stock rom

Hello everybody,
I got a new s4 mini from Poland, and I live in ISRAEL, some guy here opened the region locked problem somehow, when rooted the phone he triggered the knox 0X1.
today I installed CM10.2 on my phone (not with ClockworkMod but with Team Win Recovery Project), and I would like to go back to the original stock rom.
I think I've used backup, but after it I pressed on factory reset, and I can't find a way to restore it, does anyone know how? and if not, how can I install the stock rom again without triggering the region locking thing?
thank you for you help.

At TWRP there's menu for restore, if you see nothing under restore, that means no backups were made. Factory reset has nothing to do with restore a nandroid backup. It simply restore to the 'original state' of the current installed ROM.
If you already triggered KNOX, there's no going back. I have no idea what the 'guy' did, but rooting has nothing to do with region lock.
If you want stock ROM, you need to download the ROM file for you phone and use ODIN to flash it back.

So no backup. I mentioned the Knox because I'm afraid to downgrade back to jelly bean4.2.2. Anyway, I can't find ROM stock file for Israel for i9195. Can I use something else? Thank you for you help.

How to return to stock recovery?

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.

[Q] Please Help LG G3 D850

I tried flashing a rom into my phone.
It didn't work and I wanted to restore from the backup I made from TWRP.
I restored my original OS from TWRP, and it's booting up to it, but once it gets to my lockscreen and after a minute or so, it reboots. This happens every single time. Does anyone have any ideas of what to do?
Something is false with backup I would say.
Flash stock firmware, root it again and then play with custom rom again.
Since, I'm relatively new at flashing. I just want to make sure I am doing this correct.
So I can get the stock firmware from this site:
lgg3root (turns out I can't post the url yet since I'm a new user)
Then I would have to choose the ADB sideload option in TWRP since there would be no other way for me to flash it correct?
Also would flashing the stock firmware delete everything in my internal storage?

N4 DE, TWRP & root, stuck on VZW red screen. How to go back to stock?

Hi,
I have Note 4 DE that I've installed custom recovery (TWRP) and then flashed a SU.zip. Everything went smooth so I started installed my apps.
I also created a backup from TWRP (pre- and after root) and also full partitions backup using EFS Professional as described in this post so I should also have a phone-specific aboot partition backed up.
Today I booted up into recovery to show friend of myne how it looks like, then rebooted the phone and now it is stuck on Verizon red logo screen with slow blinking blue light. My attempt to hook up the cable and fire up EFS Pro ended up with error message saying that I do not have permanent root.
What should I do now? If there is no way to fix this and keep all installed apps, Is there a way to restore the phone to factory (while still keepping unlocked bootloader)?
Thank you in advance.

Power your phone off. Pull the battery. Put the battery back in and boot into recovery (volume up, home and power). Wipe cache and delvek. While in TWRP recovery select boot system.

Still on VZW red screen after booting up into recovery, selecting "Wipe", then "Advanced Wipe", checkmarking Dalvik Cache & Cache, wiping them out; and then going to "Reboot" -> System. ..

Hmmm, Ok. Don't worry about your bootloader it is alright, not locked. I recommend you restore your backup, either a rooted backup or a stock backup that you made right after you installed TWRP. This time wipe cache, system and delvek. I'm trying to keep you have having to wipe data, but if this doesn't work then you'll need to do a complete wipe and factory reset and then restore your backup. You may loose root, if so then after restoring your backup flash the SuperSU.zip again to regain root.

OK, once I wipe Delvik, Chache & System, then I have to do restore from a TWRP backup I did after flashing custom recovery, right?
I have these in the list:
Boot
Recovery
System
Data
Cache
EFS
Modem​
TWRP gives me a list of partitions above, which ones should I restore? "System" is probably the one since I've wiped it up already, do I need anything else?
Thanks

Yes, select restore and then select the backup you made. The backup will contain whatever partitions you selected when you made the backup (the partitions you've mentioned above). You won't be given a chance to select the partitions once you enter restore, only the backup file name.

It actually gives me an option to deselect any of partitions in the list. Which one(s) should I leave selected for restore?

Ok, well it's been awhile since I restored anything and maybe that is a new option in the latest TWRP. Anyway, do not deselect anything unless you are worried about your apps then in that case deselect data, then restore.

OK, I was able to restore backup to pre-root state (without any apps installed) and then from other backup that has some apps installed. So far, so good, thank you for helping me out.
I still have a question: how do I restore to factory? I guess I need a factory image that was replaced by TWRP, and then I will use Odin to flash it? Did flashing TWRP change the KNOX bit? Is there a way to completely restore N4 DE to factory the way it came from Samsung or once custom recovery is flashed and phone rooted, there is no way back (it is showing me "Custom" every time I turn it on)? I am still in doubt if I want to keep the phone as it is very similar to my rooted N3...

The first backup you did after you installed TWRP through ODIN is a factory image with the exception of course of the factory recovery that was replaced by TWRP. Knox will always be part of any backup unless you uninstall Knox using something like Titanium Backup. So installing a custom recovery will not replace or uninstall Knox. I caution you not to flash any factory firmware. There is no factory firmware available for the Developer Edition. If you flash a factory firmware for the Note 4 you will lock your bootloader and what you have left is a very expensive Retail version of the Note 4...locked bootloader and all. The advantage of a Developer Edition is the unlocked bootloader...don't screw that up. As far as "Custom", I don't know how to get rid of that...there is a way I just don't remember how to do it.
I just ordered my Verizon Samsung galaxy note 4.. is there a root method available for the retail version ( non developer edition ) if so can someone point me in the direction .. I'm coming from unlocked rooted note 2.. I've been searching XDA and googling the topic today and all I'm finding is just developer edition is root able .. even searched you tube.. thank you

inseek, let me correct a comment I made in a previous post "there is no firmware available for the Note 4". That's not entirely true. It is true that there is not a stock firmware .tar that you can ODIN that returns your phone to stock DE just like it came from Samsung. This thread http://forum.xda-developers.com/not...mware-firmware-kernel-modem-recovery-t2942937 does provide a few stock .tar files that can safely be ODIN on the DE. These files do not provide the "safety net" that we would like in terms of a complete flashing of the DE back to stock, it only provides stock .tar files for several "pieces" of a complete stock ROM and bootloader. Read the OP and post 2 and 3 very carefully before you use any of those .tar files. There is no .tar for the DE aboot/bootloader. The only way you can have a backup of aboot/bootloader is to follow the instructions here: http://forum.xda-developers.com/note-4-verizon/general/guide-vzw-note-4-backup-developer-t2962911

Thank you for this update, jpcalhoun.
I've followed these threads when I first flashed TWRP so I do have a backup made via TWRP (which doesn't include aboot) plus the one created via EFS Professional. I was just wondering if there is a dump of all partitions as they are coming from the factory. I am not a specialist but I was thinking that if I have aboot (which from what I read is unique for my phone), original boot partition + the remaining partitions in my backup then I should be able to restore the phone to factory state.
Is there a way to dump all partitions from a brand new N4 DE that just came from a factory? Obviously, for EFS Professional we need custom recovery + BusyBix + root to work. TWRP is capable of backing up most partitions but not aboot/boot. The way it is now, once we flash custom recovery, there is no way back as if there is something wrong with the phone, Samsung will see that "Custom" sign on the screen and from what I've read, will just re-flash a locked bootloader prior to sending the device back to the owner. I wish I knew all this prior to ordering my N4 DE

I'm not a Linux guru or a ADB guru, but I think you can do that using command line scripts, but I can't swear to it.
