[Q] True factory reset? - Galaxy S II Q&A, Help & Troubleshooting

I did search how to factory reset but in those threads people generally ask how to KEEP files and settings etc., but I want to delete everything, settings, files, contacts etc. I want my phone to just as when I took it out of the box.
I'm on stock 4.0.4 ROM, rooted, and I did delete some stock Samsung apps, will I have them back when I factory reset. And is it better to do factory reset or just re-flash ROM via Odin.
Thanks

Deleted apps won't come back to life. Factory rests turns your settings to presets (Android Version's Presets).
If you want an "out-of-the-box" ROM, you're gonna have to flash another one (as long as you didn't have a back up, which i'm guessing you don't).
If you wanna flash a new ROM, beware for the brick bug on 4.0.4.

Can I safly re-flash/downgrade to 4.0.3 ROM then update again via wifi?...

[Q] Help going back to factory state

Hi,
I have flashed villainrom but would like to go back to the original state my phone came in.
Is there a way to do that so that literally everything gets cleaned up?
Can I just do a factory reset? Will the phone then go back to the original rom? Or do I need to flash something?
I have made a back up of all my apps with Titanium Backup, copied my photos to my pc and have synched my contacts and calendar to google.
Have I missed anything?
Thanks for your help!

Flash your original firmware .

In CWM recovery mounts and storage format data cache system and sd card ,
Remove battery go to download mode
Flash firmware through ODIN

Thank you for answering me. Just to make sure, I have to flash my original firmware before and after the cleanup?
No you only have to flash the original firmware once after the clean up once you have backed up of course

where do i get the original recovery to flash???
so i flash it in clockwork recovery, and when phone reboots it is back to OEM????
what i mean is the stock GS3 software.. when i am in clockwork recovery, i wipe the system and i flash the stock software, where do i download it from?? thanks..
So you don't want to unroot you just want to use the stock rom?

see if this helps. i know when i had to unroot it worked and kept all my data but if you are taking it back to the store for warranty you may want to try the app called "triangle away". the app makes it so they cannot tell if you have flashed any ROMs.
check out the development section for how to go back to stock. once i got it back up and running..i also went to settings, privacy to do a system reset as i didnt want them to see superuser app when i took my phone in to the store.
I am still running the stock Rom, I just rooted the phone and flashed clockwork recovery.. I'm trying to do a factory data reset. To reset the phone back to the out of box state. I am under the assumption that when a phone is rooted and a custom recovery is flashed you can not just go into settings and factory reset your phone or you will brick it. Am I correct in this assumption? And if I am corect what I think I have to do is flash the original recovery, then I can reset the phone to factory settings which will wipe it back to stock and remove the root.. correct? I am just not sure where to get the factory recovery. Doesn't clockwork recovery replace the factory recovery?
Yes factory reset after having cwma will not restore back to stock. You''ll have to flash stock via computer or mobile Odin. The link provided above should be helpful

If you just want to unroot - removing Superuser.apk, su and busybox works.
CWM will stay though.
Then do factory reset and format internal sdcard. That will remove all user data.
So.. if you have clockwork recovery, and you factory reset the phone, it will put the factory recovery back?
I thought trying to reset while having a recovery flashed would lock up the phone...

If your still having trouble here, the answer this question & alot of others is at galaxys3root.com. It's one of Zedomax's sites that will give you clearly labeled & very easy to follow instructions to unroot for warranty return. He also includes a video where he will walk you step by step through the process. This is a great Site & you can find some great tutorials on the gs3, as well as rom reviews, so be sure to bookmark it! I hope I've helped
no no, i dont want to just follow instructions.. i am trying to understand CWM. i know how to use it, but every phone i ever rooted i was never able to reset back to factory settings because i was never sure if it would screw my phone up and i am trying to learn if it is safe t do. Does CWM replace the factory hboot or just install along with it? if i am rooted and i have CWM flashed, can i still reset to factory settings like normal? and if i do what will happen? will i still have root and CWM?? can i reset back to factory in ANY rom i flash safely? all that resetting back to factory does is remove accounts and .data files correct?? when you do a wipe in CWM it removes the entire OS, then you flash whatever rom you want.. when you reflash the factory ROM, unroot and remove CWM, hboot is still there correct? you dont have to reinstall hboot, right? you just have to make sure you reflashed the original ROM and uninstall root and CWM and then your back to original right?? i am just trying to understand it all thats all.. i know i can follow directions, but i am trying to learn. any site i find explaining CWM, it just explains what it does, i am trying to learn HOW it works so i can feel safe and i dont have to worry about bricking my phone. i was always too afraid to reset any phone i ever rooted because i never fully understood how CWM worked.. i always thought of our phones as a PC, where as a PC has a recovery partition with the software backed up in it, and i always think CWM wiped it clear, so if i try to reset the phone it will be looking for a partition that's not there. but now i think my PC analogy is wrong, and all a factory reset does is remove the .data files, not re install the software.. im trying to figure which one is true..
Bump
Guess were all in the same boat lol
after flashing stock back to the device, it also goes back to stock recovery. after boot, you still have all apps ex. titanium but once u open it will say no root access. u can then go to settings, privacy, and factory reset to get rid of titanium, etc so it is complete stock. no one would be able to tell of your past..lol. i was rooted earlier in week and made mistake of resetting to factory reset before unrooting. nothing bad happened and i unrooted and factory reset to take it to the store hope this clears up stuff.
if you are returning to a store flashing a stock Rom was all I needed to do a warranty exchange.

Used a custom SystemUI.apk file, Now my device won't boot.

Hello everyone,
This is my first post here , and I rooted my phone a few days ago. Today I wanted to tweak my phone a little, so I followed a video, and after pasting the new systemUI.apk in system folder, I reset the phone, and Its getting stuck @ a screen reading " Android is upgrading, starting apps"
I waited for half an hour, and now I am a bit scared. I have gone into recovery mode ( after a hard reset ). Should I restore factory settings? Or can I restore the systemUI app?
Many Thanks,
F1RECRACKER
Just restore the nandroid backup you took before you modified.
Factory reset doesn't change the rom. Only your data - so won't help.
If you for some reason didn't take a nandroid backup (although why wouldn't you?) The easiest fix is to flash a stock based custom rom

I am running stock rom, so a factory reset will do right?
No. What did I just say? Factory reset doesn't change the rom. You changed the rom (or part of it more accurately) so a factory reset wont fix it. Factory reset only wipes your data. It does not fix things you break when you change parts of the rom.

Okay, I will try and flash it with a stock rom. I am downloading it atm . I will let you know once its done.
You don't necessarily need to flash an official rom which will replace recovery, rom and unroot...
You could flash custom touchwiz roms like wanam lite or omega

DON'T do a factory reset! OP states he is on 4.04. Search 'emmc brickbug', you may have it as you're on 4.0.4. If you do have the brickbug, a factory reset will brick your phone.
OP, by 'losing your data' do you mean photos etc? If so, you can flash a new firmware (download from Samfirmware) using Odin without losing photos etc. However, you will lose your app data (settings of apps etc). Better than having a bootlooping phone though.
then forgot abt the backup

So he doesn't sync contacts to google? (in sync options, 'sync contacts'? if ticked, then all contacts can be restored to phone after signing in to google account on new rom). If you do install new firmware: to be on the safe side, flash an ICS-compatible Siyah kernel using Odin. Then you'll be safe to wipe, as Siyah has the emmc bug (emmc_cap_erase) disabled. Then, flash new firmware in Odin.
Some people report success of upgrading with no loss of data (http://forum.xda-developers.com/showthread.php?t=2116344) so you technically could try upgrading with no wipe.
Flashed New Frimware.
didnet lose any data.
all things fine.thanks guys.

[Q] Fully restore a rooted S3

I know the answer is here somewhere but I really need someone to guide me...
I bought a Galaxy S3 yesterday and it´s not my first. It came with WanamLite. I know that WanamLite is a good ROM but the phone was laggy as syrup... Last night I flashed the latest leaked 4.2.2 Samsung firmware but I really feel it´s still laggy... as soon as I do two different things in ot it lags like he**.
Now I wanna try to restore EVERYTHING to it´s factory state... kernel, firmware... EVERYTHING! I want to be able to update this phone the usual way... either KIES or OTA. As of now I just get a message that the firmware has been changed and that the phone is not supported.
So... can someone please give me directions to fully restore the phone to it´s original state?
Thanx guys!
first go to recovery and do a wipe data/factory reset and cache and on advanced wipe dalvik cache then go to mounts and storage and format everything there
then go to download mode and flash a stock Rom
So if I do that the custom recovery, root and Everything else will be as "out of the box"?
Isnt it best to use ODIN to flash Stock ROM?
Usually Stock Rom has stock recovery in it.
So if u flash with a stock rom
Then everything will be back to normal.
It is optional to use Triangle Away.
Use it only if u need to rest ur binary count

yes everything will be deleted and back to stock but your binary counter will not be back to 0 for that you will need triangle away for waranty purposes which is useless since you bought your phone second hand
yes odin is the best choice but you need to go to download mode so odin can idintify your phone you can't flash a Rom on home screen LOL
Run triangle away
Flash your stock Rom
Factory reset

Think its the easiest and best way to get back to stock..
-) Check out the latest Firmware for your region on sammobile.com,
-) backup your data / SMS etc if you would,
-) reset the counter with triangle away,
-) flash the downloaded Firmware with Odin and last do a factory reset
Yeah. Just check the flash counter in download mode first. Bootloaders since 4.1.1 have been increasing back to 1 after reboot so you need to be on a stock recovery and kernel to reset without going back to 1 .
Or you have to prevent triangle away from rebooting after the reset. Pull the battery and go straight to download mode

Everything Went fine... counter restored, and Stock flashed.
First I was worried that the phone had gotten the "Sudden Death" due to the constant freezing... AND it has the stupid chip that causes the darn thing... but after a reset of the phone it works just fine!
Thanx alot guys! I´ll hit the "Thank You"-button!
