Hi all, I am preparing to give my G2 to a family friend however I currently have it rooted with TWRP custom recovery installed. As I want to give it to them as if it were new, I need to restore the phone to its original state i.e. 4.2.2 stock jellybean, without root or TWRP installed. I currently am on stock 4.2.2 and have not flashed any roms. How would I unroot and remove TWRP? Thank you in advance for your help

1.is it possible to backup my stock rom wich i recieved with my s4 in cmw before rooting the device?
2. does restoring a rom wich you backed up after rooting will gain you automaticly root access when in restoring it? (superuser and the premissions will be installed and activated automaticly?)

Hi,
1 .Yes ,you can backup your entire system with the recovery backup.
2. If you back up a rooted system,it will restore as a rooted system.

Hi,
Look HERE
Your best plan would be to install a recovery,backup your system,and then return it to an "Official" rooted system with the link I gave you.
On the thread there is a link for a stock recovery to return you to stock and be able to receive updates.
The thread I gave you ,the [OP] is constantly updating his ROMS,so you will not lose out on updates anyway.

i have on other hand found and downloaded the exact stock rom of my s4 to my pc from a local android website
so if something goes wrong and i need warrenty will flashing the stock rom wich i have download via odin after rooting via cwm will remove them completly? (will remove the cwm and root after flashing via odin?)

Hi,
It depends whether the stock ROM contains stock recovery.
I doubt it.
You will probably have to find a stock recovery somewhere.

have spent the last day boning up on rooting my t-mobile s4 4.3 and still feel that i have too many questions, and i consider myself pretty tech savvy, at least in terms of pcs! anyway i'm someone could help me with the following questions:
1. can i take a snapshot of my current (stock) setup before i root, which i would be able to reload in the event i find rooting is not for me? i'm talking about a backup, image or snapshot of everything that's now on my phone which i can restore if needed, returning my phone to it's exact state before i rooted?
2. when i root my phone will it delete such things as my contacts, photos, apps, etc? or will that only happen when a custom rom is installed after rooting? if the latter, i'm guessing i could do a full phone backup after rooting using something like titanium, and the flash a custom rom which would give me a clean os, free of all samsung's and t-mobile's bloatware? and if i decided a rooted phone wasn't for me, i could restore the backup of my original phone using titanium?
3. when i root my phone and install a clean, bloat-free os, what sort of thing will no longer be possible in terms of my provider's (tmobile) services? for example i guess i would no longer get automatic ota's? how about tmobile notifications or the like? will tmobile be able to access my rooted phone as they are able to do now? and if not are there any disadvantages to this? i'm guessing there are more advantages to this.
4. so once my phoned is rooted and a new rom flashed, is it a relatively easy process to reload all of my contacts, photos and settings?
5. and, finally, someone recommended that i use the rotting steps outlined at galaxys4root.com, do you agree?
thanks very much in advance, what a tremendous community!

Hi all,
I am interested in the CM11 ROM. Last night I spent 6hrs trying and failed, epically.
Here is what I did already:
1. Downgraded from 4.4.2 back to factory
2. Successfully rooted
3. Installed ROM Manager
4. Successfully downloaded CM11 and latest GApps
Then when I tried to boot into recovery it kept going to a screen with a little android guy lying on his back with a red triangle!!! I tried six times.
I got frustrated and just updated back to 4.4.2 and have been dealing with it. I am still rooted and have been able to remove my bloatware and other things you need root access for.
Any thoughts or help as to how I can install the CM11 rom?? I am happy running NovaLauncher and using DynamicNotifications to approximate it but really want to try out CM11.
Cheers and thanks!
Lucky there is no way to root on 4.4.2 yet or atleast no Recovery's yet it could be worse you're atleast rooted and it didn't brick your phone

Did you actually try flashing a recovery first? Just installing ROM manager won't install the custom recovery needed to flash ROMs. You have to do that step as well.

No, I didn't. I am super new with android. Had an iphone for a long time. How do I flash a recover? Can I still do it now on 4.4.2 b/c its rooted?

LG blocked the Loki exploit with 4.4.2 so you can't flash recoveries currently. You'd have to flash back to 4.2.2 to do that. Which if you want custom ROMs now its going to have to be done sooner or later. Which carrier and model number do you have? If you have an international D802 the above post by @zekurosu will work for you, otherwise don't use that one. You're gonna have to find the method for your model number.
My first guess was that you missed the flashing the custom recovery step, which people above me have already helped ya out on. For being new to Android you did fairly well, you just missed that one step.
Good luck!

I have an ATT D800 running 4.4.2. I can't decide whether its worth it to flash back to 4.2.2 to try again. Pretty happy with NovaLauncher + widgetlocke and fairly closely approximates what I am looking for.
For what its worth, I was in 4.2.2 when I tried the first time and failed. I think mackster is right, I didn't flash the custom recovery. I basically flashed back to 4.2.2->rooted->tried to boot into recovery (OVER and OVER) then gave up and upgraded back to 4.4.2.
Thanks for all the help. At least I now have a rooted phone and have been able to do some cool stuff with that. My goal is to get nexus 5 software in an LG G2 body (battery, camera, etc)
@android_nashville There's a way to have the best of both worlds. You can flash back to 4.2.2 (10d preferably) root, flash a custom recovery with Flashify or FreeGee. Both available on the play store. Then actually update to 4.4.2 following this thread http://forum.xda-developers.com/showthread.php?t=2483043. Eventually, if you want to flash custom ROMs you're going to have flash back to 4.2.2 and do this process regardless. The 4.4 aboot image (bootloader) can't be bypassed with Loki. Its been blocked. But some brilliant devs basically found out they can make a hybrid setup, with the 4.2.2 aboot, and everything else 4.4.2. This way you can have the ability to flash custom recovery, kernels and ROMs.
So, a while back I installed the KitKit ROM for ATT before any custom ones were out.
I'm trying to flash the stock back onto my device with LG Flash Tool but it keeps telling me I have the wrong device for the .tot file and .dll file. It seems like my D800 is recognized as a D802 international G2. How can I fix this?
In settings > about phone it shows it as D800, but under software it shows D80220a. I also tried to install a custom recovery but that didn't work out. Gave me a certificate error.

it sounds like you have a custom rom like poweruser anyways if your device is d800 but shows d802 then you can try the dll in the poweruser thread which ignores model check for d800 only

Yup install official att stock rom then acheive root using ioroot25 or ioroot23 after that install Autorec(by cloudyf) this will adjust your bootloader and install a custom recovery. after that install any custom rom you want.

Let it be known that I did NOT install the official stock KitKat ROM it was the other one,4.2.2. Will AutoRec still work?

I know its for D800, what I meant is whatever version his phone got changed to, this DLL will bypass model check; therefore allowing him to flash back the ATT stock. Maybe I should have worded differently.

Yes there is a way, theres an app you can install called Autorec, this application will automatically set up a Custom Recovery for you to backup your files, here's a Link to get started.

Thanks for the fast reply, well i read this comment on the link you game me, im just curious and also worried that i might brick my phone, cause im a total noob when it comes to these things,
Here's some of the comments i read about D802T
"Please note you cannot install custom recovery in stock KK via any method for the D802T Australian variant and get it to boot. LG has not released kernel source code for Aussie variant, for KK, so Loki exploit does not work. If you want a custom recovery under KK you will have to install a custom ROM with already patched kernel. If you plan to stay on JB 4.2.2, however, you can indeed root and/or install TWRP without hassle on stock."
"u cant use this on the Australian version D802T.
It will soft brick your phone."
Now what should i do? im just very confused.

there is a way to do it. Follow the guide and root kk but before you install autorec, make sure you have a custom rom zip ready to go on your phone sdcard and whilst still in TWRP (dont try to boot into kk yet), simply flash your custom rom, and then the phone will boot normally.
Hi guys,
I did root my device recently, is there any way to re-lock it again as I need to bring it back to the company?
Flash the latest firmware using Odin or initialize using smart switch. This will wipe the the data on the phone.
Stop making a post on this, multiple threads here that talk about fixing this.

Do you mean the rooted rom or the rom you have after the reset. You could backup using flashfire if rooted. Smart switch works for non rooted devices and rooted devices but will not backup app data.

Re-flash the original firmware. It won't be rooted if successful. Therefore it would be completely stock again.
