Cold Boot/Wipe Data/Factory Reset - Transformer TF300T Q&A, Help & Troubleshooting

Hi,
Can any expert tell me the difference between cold boot/wipe data/factory reset?
I know cold boot clears up the cache and all user data/apps will stay. Root will stay too.
factory reset will erase everything and all user data/apps will be gone. Will root stay?
How about the wipe data in cold boot menu?
Will we lose all user data/apps by choosing wipe data? How about root?
Thanks.

As far as I know Wipe Data in the boot menu and Factory Reset are the same thing. As you say they will delete all user data and apps, leaving only system apps. You will lose root when doing this, but I have read that you can restore with OTA RootKeeper (if you backed it up before doing wipe), since this will be stored in the system part of the drive which doesn't get wiped. So you will need to redownload RootKeeper and restore root. I have not tried this, but from what I have read it seems to be possible.

Scroll down to bottom of page. Good description of cold boot vs reset.

Factory reset will not touch the su binary (/system/bin/su and/or /system/xbin/su), which is what root depends on.
You'll need to reinstall superuser or supersu, but the actual rooting will stick.
Wipe data PROBABLY works exactly the same.
Factory reset is in other words safe for root.

how to do a correct full wipe?

Hey guys, this might be a really noob question. I looked it up on google, but still wanted to make sure because of the verizon locked bootloader etc( i know we can unlock it now). How do i do a full wipe on my device? I am asking because there are a few more options in the wipe settings of the custom recovery i have.
This are the steps i always do before flashing a rom. Are they the correct steps or do i need to do something else?
Wipe Cache
Wipe Dalvik-Cache
Wipe Data/factory reset

Wipe Cache and wipe dalvik cache should both be done when flashing modifications or tweaks as they reduce the chance of encountering data issues/glitches and neither of them wipe your data as they are merely caches. Wipe data/factory reset should be done before flashing a rom. Wipe data/factory reset automatically wipes the cache and as the name implies will wipe any data you have on the phone, though any files you have saved to your internal "sd card" will be left intact. Before flashing a rom I always do a factory reset, and a dalvik cache wipe. Additionally I have found it helpful to also go into mounts and format system. There have been times for me that switching between two different roms has led to choppy performance, and this step seems to fix that as it thoroughly removes any traces of the previous rom.
Thanks for the detail reply. Is useful to know this since i always flash roms

[Q] Factory Reset wipes root!?!?!

So i rooted my tablet when i had ISC then i updated to the latest firmwares but the question is if i factory reset my tablet will i lose root again? I did this once but i lost root (super user deleted). So i had to down grade and reroot ics and i just updated again but im wondering if the factory reset is basically losing my root or is there an error to prevent this? I want to factory reset my tablet since everytime i update my tab in order for it to run smoothly like other systems. If anyone has an answer please let me know! Sorry if you dont understand my english -_-
Hell-o Niceguy and welcome!
Try cold booting first in order to save your root.
Factory reset will wipe all and place you back at the factory state.
So yes your root will be gone.
Hope I have understood you correctly.
I've never done it myself, but factory reset should not modify the system partition, so it should not be possible to lose the su binary that gives you root access.
Rationale: The system partition is read-only in normal use, and there is no other partition that contains the unmodified factory image of the system partition.
Flashing a complete Asus firmware however overwrites the complete system partition, which *will* kill your root.
Updating the Superuser or SuperSU apps through the Play Store can place them in the data partition instead of system. They would then be lost after a wipe. You could try reinstalling from the Play Store...

[Q] What do the various ways of resetting the Moto G actually do?

What do the various ways of "resetting" the Moto G actually do? Which, if any, result in changes to phone user data versus phone applications or phone configuration data?
In Kitkat 4.4.4 there is Settings->Backup & reset->Factory data reset. What does this do? Does it just reset all the account and user information so that one is required to enter or create a google account? Does it affect any applications that were installed by a user? Or does it remove applications that were installed on the phone by the user since the phone was first used?
When you unlock the bootloader of the phone, it is "wiped". Which reset is done when this wipe happens? Is it equivalent to doing the Factory data reset above?
My phone is rooted and has twrp recovery installed. In twrp, there two wiping choices:
Wipe->Factory reset
Is the factory reset in twrp the same as the Settings->Backup & reset->Factory data reset?
Wipe->Advanced Wipe, which allows checking Dalvik cache, Data, Internal Storage, Cache, System, microSD card, USB OTG
If you select to wipe Dalvik cache, Data, and Cache is that the same result as doing the Wipe->Factory reset just above? If you wipe System, then you no longer have a bootable phone, right? What about Internal Storage?
I also have Xposed installed which makes changes to system files to customize android. How, if at all, does this affect what happens when the phone is "reset"?
Am I correct in assuming that the only one to return my phone to stock kitkat is to reflash a kitkat rom? What will happen if I do the Factory data reset under Settings, or the Wipe->Factory reset under twrp on my phone which has an unlocked bootloader, many applications installed, and Xposed and many Xposed modules that get loaded when the phone boots?

The super user apk is stored in data so you will lose that if nothing else when you factory reset

Factory Reset via TWRP on Stock rooted HTC U11

Hi guys,
I wanted to perform a factory reset without loosing the stock ROM for now.
I don't do this since a long time ago (I did that on M7) I just wanted to ask a confirmation about that on TWRP Recovery.
What I need to do? Is WIPE -> Advanced Wipe and select DATA, Internal Storage, Cache and Dalvik Cache enough?
Basically I can wipe everything except system and boot right?
I've read something about formatting partitions but I'm not sure.
EDIT: I've found this: TWRP --> WIPE --> Swipe to Factory Reset
No more else should be needed.
