Factory Reset on rooted A100

My A100 is rooted (not touched the bootloader/installed custom ROM) - when i do a factory reset my understanding is that it will still remain rooted (I used ZeroNull's simple rooting method).
So when it's reset - do I simply re-install the Superser app and then Titanium backup - and then reinstall the backed up apps I want - or is there some step I'm missing here?
Thanks!

Factory reset is just that, goes back to how it was from the factory for the rom. In case of stock, no root. Just redo the root again. Or just check for root after the reset, but I doubt it stays.
Edit: after re root use TiBu to restore whatever you want, as its the same rom restore data too, unless some bug is why you want to reset.

Just did a factory reset. As expected it wiped everything - but I was still left with root access.

Ok good to know, thanks for letting us know. I didn't run stock long enough to do a reset on, but my other phones and tabs lost root.

Note that if you deleted any apks and do a factory reset, they are not restored. I deleted several apks for many of the preinstalled apps, and after I did a factory reset, they were not restored. So a factory reset does not really return the tablet to the state it was from the factory(no root, all system apps installed), rather it wipes all user and app data.

Yeah I should probably have mentioned it doesn't do much, if anything, to /system. Any changes there are likely left alone, which is why root stayed. The last time I did a factory reset was on my evo and it lost root for some reason. Same with my rooted stock nook, before cm7.

Boot Loop After Rebooting?

My GNex is boot looping, and all I did last was install the tasker app. I can't figure it out, it was working fine all night, then when I switched batteries, bootloop. I even tried to switch back with no luck just for kicks lol.
I can get into Clockwork recovery, but it will not let me access my internal data, I never could and its the one thing about Gnex that bugs me... Actually it pisses me off, because even when the phone is on and I tried to backup my phone, sometimes the transfer fails or stops!
I really don't want to format my phone I want my data back at least before I do a wipe. I did a backup in CWM but again mounting data, even usb mount won't work. Clockwork Recovery 5.5.0.4.
Any advice?

Do you still have the rom? If you do reflash it, you won't lose anything if you didn't factory reset.

I don't know maybe somewhere, it was the first Jellybean rom. Even so how can I reflash, I cant get access to my data in recovery? =[
I found the rom, just need to know how to get into data/usb from CWM?

The simple act of flashing the ROM won't delete your data. Its why we have people delete it when switching roms

What could be causing bootloops on AT&T SGS3?

Hello,
I am from the i9300 forum. My GF has a SGH-i747. When she updated it to official Jelly bean using Kies, all seemed to go well but then when she booted up to her home screen the phone would reboot. It would continuously do this over and over again.
So we had to use KIES to do a complete format of the phone and reboot it. This deleted everything and made it factory brand new again. This is that option where you have to type in your serial number into kies to do the emergency firmware recovery.
Well a few months went by and today while my GF was using her phone it froze and rebooted. It is now stuck in the bootloop. I don't understand why this is happening. She doesn't have the phone rooted nor has she flashed anything on it. I'm not familiar with the SGH-i747 so I'm not sure if this is a common bug that has been addressed for fixed.
Please help, my GF needs her phone for work and she's a few miles away from me. Any help or advice would be appreciated.

Might've to get in recovery (hold vol up+home+power), clear cache, reboot.
If that doesn't work, back in recovery and factory reset, then reboot.

Yeah, I tried all that. I managed to back up her data so maybe we can restore her apps and information later. But this is similar to last time. I had her factory reset it, wipe cache, wipe dalvick, format system and format data.
We then followed by restoring her backup but the problem still persist. I might need to flash the stock ROM.
Could Fix Permissions fix the problem? It seems that the phone boots up to the home screen. While loading files, something at this point is causing it to bootloop. It will freeze after a few seconds and then reboot and repeat the problem.
Something is definitely conflicting within the first 30 seconds of booting up to the home screen. Any ideas?

Debloated stock ROM might be a good idea. When restoring, you might be bringing the problem right back. It should be very minimal (the needed stuff that you can't simply re-download or re-setup) to avoid issues coming back.

I edited my post above about fixing permissions.
But this is very similar to what happen last time. I had wiped factory reset, wipe cache, wipe dalvick, format data and system, installed fresh new ROM and that boot looped too.
It took KIES emergency firmware recovery (where you have to type in your serial number) to fix the problem, but everything was deleted even the internal SD card.

I doubt fixing permissions will change much but could try it.
From the way you describe it, it sounds like a app or some bad data. Is she using a external SD? If so, try booting without it. If not, my guess is that there's a rogue app or something corrupted her data.

Thanks. Yes she's using an external SD card. I will have to get a hold of her phone and see what's going on. The first time it happened was because we upgraded to Jellybean. it happened right after so I don't think it was a rogue app. This time she just pulled her phone out of her purse and noticed it boot looping. Something sounds wrong with her phone... I think we might need to send it back for warranty repair.

Okay I need help. I have discovered the problem and it is the SUPERUSER app. When Superuser was updated it caused my GFs phone a boot loop.
Now that I put fresh rom and cleared everything her phone was working. But the moment I rooted the phone itboddly didn't come with SU, so upon installing SU nothing could access SU for some odd reason. So I found out you need a SU for Jelly Bean, upon installing this version of SU is when everything went to he'll and the same boot loop came back.

What rooting method did you use to root your girlfriend's phone?
If I'm not wrong, most of the rooting method -- if not all -- for the SGH-i747 involve the SuperSU app instead of the Superuser app. And I believe most of the custom ROM, if you switched ROM, come with SuperSU pre-installed. If you try to install Superuser (without removing SuperSU), might that be the cause of your trouble?

Perhaps, I will try and fix the problem again. We just got back from a movie. Thank you.

if everything doesn't work
here's what you should do
first go look for AT&T 4.1.1 stock rom
download ODIN
go to recovery by vol up + power + home
clear cache, data and dalvik
flash stock rom thru odin.
that should fix soft brick

factory reset sprint galaxy s3 and my files are still on phone

hello everyone. i'm having a problem my phone is running extra slow. i'm rooted on stock, dealing with the official crap 4.3 fw. i tried to factory reset my phone. i wiped the data,cache, dalvik and fixed permissions. after the factory reset super user, internal files and teamwin recovery is still on my phone. once i start installing any apps the phones starts to run like the first gen android. i need help. i would like a complete full wipe that will revery everything completely back to stock.
i've already searched before making this post. i didn't see anything any results that had problems of these files staying on phone.

Odin back to stock. You will need the 4.3 tar.
Or go here

Make sure you format data and system. Factory reset only wipes data, txt, contacts, apps but not system apps like superuser.

thanks for the info. i fixed my problem before having the chance to see you reply. i guess that is the only way to do it on 4.3 while on 4.12 that's all i did to get back to stock it wiped everything including super user. i will bookmark this info for future issues with this crap fw. thanks again for the info.

[Q] Encrypted device on new ROM

Phone was rooted and running CM10.2 nightlies just fine. I had to encrypt my phone for work email, no issues. I now want to change ROM's to a TW because of WiFi Calling.
So here is what I did:
- I did a TWRP (2.6.3.1) backup before starting
- Advanced Wipe Dalvik/Cache/System/Data/Internal Storage as well as Format Data to remove encryption
- Downloaded SWARMROM, flashed ROM, Modem, SuperSU.
Flash went good, rebooted with T-Mo splash and boot animation. Before I can do anything, I get a prompt to "Enter your PIN or password to use the encrypted device memory". My old password doesn't work and it won't let me in. All I can access is Emergency Call.
I have even formatted my external drive thinking it might be what is still encrypted, re-ran the install process, but same result.
I did trip the KNOX counter somehow, if that matters.
Any advice?

Go back into recovery and restore your backup, reboot and remove encryption, use titanium backup for app data

The backup doesn't have encryption. But there is somewhere on the phone that a Stock ROM is detecting encryption from. I can go to any Cyanogenmod 10.2 ROM, but not a Stock or even OMNI.

Finally got it.
ODIN root66 Stock ROM, reboot to encrypted error. Boot into factory recovery and wipe/factory reset, then wiped cache for good measure. Rebooted and it came up without the encryption prompt. Let the WiFi Calling commence.

You saved my arse today, THANK YOU! I have been out of the flashing game for some time now so I was getting stuck when I had the same issue as you, but thankfully, now it's back to normal, phew!
