Hi. Despite much searching I have been unable to locate exact information pertaining to my query. I purchased an HTC HD2 from ebay primarily because it is operating Android (Cyanogen Mod7) instead of Windows. The phone would appear not to have been factory reset and as a result I am unable to set up a Google account, etc. My knowledge is very limited but I want to do a factory reset but not delete the Android OS...how do I do this? MAGLDR V1.12 is installed and there is an option to hard reset but I do not want to end up with an empty device with no operating system. I do not have a memory card installed. Help would be appreciated. Thanks, Scott
1. turn phone on amd hold power button all the wayy through go go go as magLDR loads
2. choose AD Recovery ( option 5 i think?) in magLDR menu
3. once recovery boots up ... find the option to wipe user data ( sorry its been to long since ive had to wipe data from an old rom ;-)
^ the above (wipe data) is clearly marked as such!
this will reset to newly flashed shiny new fresh android rom
@rubledub - Is there an "ad recovery " option in magldr 1.12?
I started answering just as you have a few hours ago, but stopped when I realised magldr isn't 1.13.
also, be advised that some builds span the system as well as the sd-ext partition. the "factory reset" option in clockworkmod (CWM) wipes the sd-ext in addition to the data and few other partitions.
therefore, if you are using such a build that relies on the sd-ext, then format the relevant partitions manually. alternately, take a CWM backup, then use the "factory reset" option, and then do an "advanced restore" to restore the sd-ext portion (because it will have been wiped during the "factory reset").
you mentioned that it is a cyanogenmod build, which means it is VERY VERY LIKELY NOT relying on the sd-ext to store the build's system files, so "factory reset" inside CWM is the recommended option for you.
the above posts may be correct, i.e. magldr 1.12 might not have support for CWM...even if it does, the build installed might not be a CWM build (there are two types: CWM zip or magldr image).
just a few things to consider.

Hey, im using this ROM (http://forum.xda-developers.com/showthread.php?t=905060) now and its fine, but i would like to hard reset the os (installed half of the market ) not rly but i tried very much and i wanna get a "brandnew" version of the rom.. is it possible to hard reset this rom, or do i have to install it again or how does it work? or do i hard reset like i would do with the custom 6.5 rom?
Helgon
just wipe data, dalvik and cache. you can do this through the cwm menu. as far as i remember there is an option called "factory reset". it will wipe the data automatically.
what is dalvik? and what is cwm? and i didnt find something like a "factory/hard reset" in the settings
That's all stuff for NAND Android ROMs, if you are running Android from your sd card, just delete data.img from your Android folder (the folder with CLRCAD.exe and Haret.exe inside)

no, my rom is nand
Do you have clockwork recovery installed, or did you install a dft rom?
If using a dft rom, you can download the version of clockwork that will run from you sd card and use it to wipe your data and cache partitions, afaik. Sorry I don't have a link to it for you, but if you scour the stickies you should be able to find it

If you don't have CWM installed check out this thread
ClockworkMod Recovery for HD2 - v1.3
And in the thread of the rom your interested in,the op should mention which partition layout is needed to run that rom. And flash it via MAGLDR
if you have ClockworkMod Recovery then
1. Restart your device
2. Enter MAGLDR with holding down power button
3. Select "AD recovery mode"
4a. Optional but highly recommended take NANDROID backup:
- Select "backup and restore"
- Select "Backup" takes sometime (be patient while
backing up Dalvik cache)
4b. Select "wipe data/factory reset" takes sometime
5. Select "wipe cache partition" takes no time
6. Select "advanced"
7. Select "Wipe Dalvik cache" takes no time
8. If you don't want to preserve app. then also clear SD
9. Reboot with "reboot system now"
10. thats all

That's because this is the HD2 forum so of course the solution posted here doesnt work. Find the forum for your device and post the question there instead.

Hi,
I have an HD2 with MAGLDR and CWM. Now i want to update my Hyperdroid ROM because of some issues. The Last Time i did this, all my previous installed apps, sms and contacts are still there.
How can i make a complete clean installation of all this?
Thank you,

I sugest to flash "daf.exe" application to recreate boot. And OFC from cwm partition/format SD if you want clean installation.
If you have problem with some roms, put task29 and fix permition
GL
flashing from zip overwrites the boot and system partition, and 'wipe data/factory reset' wipes sd-ext, cache, data and clears the .android folders on the fat32 partition, so unless you want to change the partition size, there is no extra benefit in reflashing cwm (which is what "flash daf.exe" means, for anyone that has only used the flashing tool) and as for task29,,, well i've always considered that to be superfluous except in times where things are genuinely wrong, and indeed doing a full "task29, cwm, rom flash" every time (some people even consider re-flashing hspl, the radio and magldr a 'clean' install ) hugely increase the load on the nand blocks, and considering the number of 'bad block' threads that have been coming up the last 6 months, keeping the number of writes,wipes and rewrites low has got to be top priority.
(course, just my thoughts, I'm no electronics engineer or dev )
I want to have a clean install on my Nexus, and I was wondering what it meant to "WIPE". Is it Factory reset, cache, dalvik cache, and system? Or is it also system too?
I have TWRP
Thank you!
factory reset. when you wipe data, you factory reset. that automatically wipes your cache and dalvik too.

Thank you so much for answering all my stupid questions. So If I wanted a new clean start for my phone (while it still being rooted and not losing all my SD card files) I would just have to do a factory reset, then flash?
Unfortunately, the terminology seems to vary from device to device and even from recovery to recovery.
It can mean either (a) "destroy the filesystem and rebuild a new blank one" or it can mean (b) "don't destroy the filesystem but delete all the files in it". In both of these cases, access to all files are lost, but there are subtle differences for the flash memory with regards to whether the blocks are marked as erased or not.
As regards to recent versions of TWRP, the "factory reset" button underneath the Wipe menu does not behave exactly like either of the above cases (although it is more similar to case (b)), nor does it behave the same way as the stock recovery's version of "factory reset", which deletes EVERYTHING in /data.
TWRP's version of "factory reset" erases everything in /cache, but when it comes time to deal with the /data partition, it avoids erasing all the files in /data/media. This is where the "internal SD card" files are stored INCLUDING ANY BACKUP FILES you might have made (if you didn't use an external storage for the backup)
Here's what I would recommend when using the Wipe menu in TWRP:
1) Put the tablet down on a table before you enter the Wipe menu - don't hold it in your hands. The reason for this is that none of the touch buttons require confirmation, so an accidental touch could lead to an immediate disaster involving loss of your backups.
2) If you are installing a new ROM from scratch, the only button you need to use is the "factory reset" button - nothing else. (Performing Dalvik wipe or Cache wipe are superfluous as the "factory wipe" button takes care of this) *1
3) If you are installing a ROM which is a small revision from a prior version - and the ROM dev has explicitly indicated it is OK to do a "no wipe" install, use only the "cache wipe" and "dalvik wipe" bttons. *2
In short, you should really only use the top four buttons in TWRP under normal circumstances. Especially you should avoid the "wipe data" button unless you are:
- selling the device or returning it
- some disaster happened where the /data partition fails to mount any longer.
*1 It is somewhat unusual that ROM devs fail to add a wipe of /system in their scripting prior to
installation; so typically using the "wipe sytem" button is not needed for new ROM installs, and it is cerainly not desired if you want to do a complete reset of whatever ROM is already installed.
*2 Doing this kind of thing is just asking for trouble - understanding and using the Titanium Backup along with full-wipe installs is a better idea.

Ok, I come from the Apple world where you have to restore the iPhone / iPad first to update to the latest iOS then re-jailbreak.
With the N7, if I wanted to upgrade to a newer version of Android (currently on 4.2.2, so whatever comes next), would I have to re-flash the N7 to stock 4.2.2 then re-unlock and re-root it?
What if I just want to do a factory reset to start over? Do I have to re-flash stock 4.2.2 then re-unlock and re-root in that case too?

To do an official ota yes. There are stock odexed/deodexed ROMs you can flash in the dev forums without having to go through that though.
Sent from my Paranoid 3.0 Nexus7 running M-Kernel mr1
Locking/unlocking of the boot loader is completely independent from other "rooting" activity. Under normal circumstances, it is only unlocked once and then left that way.
In Android, there are 5 principal partitions: recovery, boot, system, data, and cache. In pure stock devices, it is intended that recovery, boot, and the system partition are always used in a read-only fashion by the end user. All user changes, customizations, settings, and data are recorded into the data (sometimes also called "userdata") partition. (The cache partition is used for temporary/transient stuff)
So, the Android "factory reset" is not precisely what you are thinking of - it is a procedure which erases only the cache and data partitions. IT RESTORES NOTHING - IT ONLY DELETES.
So, if a device "rooter" comes along and alters the boot/recovery/system partition, those changes stay on the tablet/phone even when a "factory reset" procedure is performed. THOSE CHANGES CAN BREAK THE SUCCESSFUL INSTALL OF AN OTA BUNDLE, so, yes - it is generally cleaner to install a pure stock ROM for the purposes of performing an OTA upgrade... at which point you need to re-root and re-customize ( not including the boot loader unlock step).
One more thing, too: because the Nexus 7 has no physical SD card, it has an "emulated" SD card which is stored in the /data (userdata) partition. When the "stock recovery" performs a "factory reset", it erases EVERYTHING in /data - including this psuedo SD card! The newer versions of the CWM or TWRP custom recoveries define "factory reset" a little differently - they erase everything except what is stored in the /data/media/ folder - the location of the emulated SD card (usually /data/media/0). This is important to understand, as your backups will be stored in there.
HTH
PS There is no need for you to "hurry up and install an OTA" if you are using a well supported custom ROM - generally after a few weeks a ROM dev will rebase their ROM onto the new release, and you can simply "dirty flash" the replacement ROM over the top of the existing ROM. That will save you some effort if you just wait a little.
So I just unlocked and rooted my N7 last night.
Since it is unlocked and rooted, do I have to do anything different if I want or have to perform a factory reset (using the hardware buttons to go into recovery mode and use the "wipe data/factory reset" option)?
If I do this factory reset, it stays unlocked right? Does it stay rooted too?

Yes and Yes.
PS. The most important skill set you can develop right now is making backups using the custom recovery. You should be 100% comfortable using the backup/restore menus of the custom recovery ... and almost as important knowing where they are stored so you can get copies of them off the tablet for safe keeping.
Thank You!

Thank you bftb0:good::good:
Just before harming my phone because of any potential ignorance, I wanna ask: If I'm on LG G2 (D802) with a rooted stock LP + TWRP v2.6.8.1 which I've installed via an app called "AutoRec". Does that imply I've KK bootloader and ready to flash the zip file of Cloudy? Also will I get app notification badges with this ROM right out of the box?
Thank you in advance!
You are safe to flash, go ahead.
Not sure about your 2nd question, sorry.
i'd suggest to update your twrp to at least 2.8.7.3 just to be on the safe side...
autorec installs an older twrp version by default
you can update twrp just by simple flashing the newer version
1. download the newer twrp for your device variant
2. enter twrp
3. flash newer twrp
4. reboot to recovery
if everything went ok, twrp will show you the newer twrp version in the top left corner
now you can flash the rom
btw app notification badges are not present in any stock based rom such as cloudy...
you can have that option by using an app like Tesla unread in combination with Nova launcher
Thanks for your inputs Andeby & 60nine!
@60nine
In fact, I flashed before I've seen your post but it's good to update the TWRP anyways. I think I've seen v3.0.0 somewhere but I'm not sure...
I've seen badges for FB so I think badges are working OK with this ROM out of the box.
I'm still teased about the "Accounts & Sync" page since it doesn't allow me to selectively choose which accounts to sync or not sync as I've seen in different screenshots that came from different skins. In LG's skin, It's either sync all or sync none which is a bad implementation in my opinion and I really wished they've addressed this in the 2 official updates they pushed to me (KK & LP) but now I don't have any faith that they 'll push any "M" update, not to mention that sync setting I'm annoyed about so I'll have to live with what I've until I get a new phone (hopefully it'll be the 5.5 inch version of the coming Nexus, if it'll have that e-sim technology :fingers-crossed
P.S. I'm not sure why LG implemented the selective sync feature in some of their older mobiles but not the recent ones!!! (as I've seen in the screenshot in this thread http://android.stackexchange.com/questions/55728/how-can-i-select-the-apps-to-sync-when-auto-sync-is-turned-on)
about selective sync
some apps allow you to turn the sync off (i.e. soundcloud that i use)
google on the other hand has the selective sync that you can turn on/off for each google feature (calendar, gmail, fitness, contacts...)
it's accesible when you enter "accounts & sync" in settings, then choose "google" and click on your google account email address...
i think that's the lollipop and per app thing, not LG specific...
about twrp version
2.8.7.3 is confirmed almost 100% stable and working with all latest roms...
latest version is 3.0.0.-4, but it's still in development (although it works just fine for me since i flashed it)
also - make sure you're using blastsgator's twrp

Thanks for all the info. I'm just not sure about the last line you said about using Blastsgator's twrp. Is this some person's name who modified twrp? I installed my twrp via autorec because the twrp manager app didn't work for me for some reason so I'm not sure how to update twrp other than installing a newer version of autorec (if there's such one) that will update the twrp for me i guess

xda thread - http://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705
to update twrp
- simply flash newer version via twrp itself
- reboot to recovery (not to system)
- check if the newer version is displayed in the top left corner
- continue with your flashing or whatever you want
also, make sure you download the proper variant of twrp which suits your model (i.e. d802)

Just one more question: In the TWRP manager, Install, I have options to select these:
Backup: No
Wipe Data
Wipe Cache
Wipe Dalvik
For the last 3 wipes, are they talking about wiping the old recovery itself if I wanna wipe it before installing a newer TWRP version? Is it the same for backup (i.e. if I wanna backup the older TWRP version)? I"m a little worried that these options have something to do with the ROM itself (system) I'm currently on!
What I'm planning to do is to leave these options unchecked & add the zip file I downloaded from the internet, then hit "Flash Now" OR it's best to wipe the old recovery first before installing the newer one? (similar to clean flashing a newer ROM).

i'd stongly advise you to use flashing directly from the recovery itself - not from twrp manager...
to do that:
1. copy your rom zip to the sd card (internal memory) somewhere - i.e. in the root of it
2. reboot to recovery (twrp)
3. choose wipe > advanced wipe
4. select wipe for system, cache & dalvik (DO NOT select internal memory because it will wipe your internal SD card where you've put the new rom zip)
- you can also choose "data" if you want a full clean install (just make a backup of your data - to your PC or something)
5. go to recovery homepage and select "install"
6. choose the rom zip from your internal memory
7. press install/flash
8. aroma installer of the Cloudy3.3 rom should pop up - follow the instructions
9. choose your device variant (in your case it's d802 if i remember well)
10. choose those additional options to your liking (no need for removing LG cover app for xposed to work properly - it's been fixed in xposed itself since then)
11. when the rom installs - you can reboot your device
first boot will take some time - sometimes you'll see just a LG logo and flashing leds for as long as 5 minutes until the "android is upgrading" screen popup appears...
good luck...

wipes explanation
- wipe system - wipes the old system partition (i.e. old rom files you had)
- wipe dalvik - wipes the dalvik cache for apps
- wipe cache - wipes the system cache
- wipe internal memory - wipes the devices sd card where all your private files are (if you wipe that one - you will lose your images, music, etc. - and there is no way to get them back after you do this)
- wipe data - wipes the personal data (contacts, phone log, messages,...)
most common wipes are
- system, dalvik & cache (when you want to keep your personal data & files)
- system, dalvik, cache, data (when you want a completely clean install)
- system, dalvik, cache, data, internal memory (same as above, but do that ONLY if you're installing your new rom from usb/otg stick, not from internal memory)

but I've cloudy3.3 already installed and everything in it have been set up (settings, software...et) and I'm pretty satisfied with it as it is much more useful than original stock ROM. What I'm talking about is updating the recovery manager itself (TWRP) from the older version I have (2.8.6.1) to the newer version (2.8.7.3). I assume that it's possible to update to the newer one without any harm to the system currently installed. Right?

oh, sorry then...
then just do this
1. put new 2.8.7.3. twrp file somewhere on internal memory
2. reboot to recovery
3. press install
4. choose the new 2.8.7.3. zip
5. press install/flash
6. after the flash is over - choose "reboot to recovery/twrp" to see if everything went ok
7. if everything went ok - reboot to rom
no need for any wipes
Never mind! Thanks for all the valuable info
