Hard Reset an Android OS? - HD2 Android Q&A, Help & Troubleshooting and Genera

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?

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.

New rom flashed. need help!

i'm newbie so i'm sorry if i make mistakes..
since i had problem with TyphooN CyanogenMod 7 Nightly v3.2.1
i have flashed this Rom (thanks ti tyween) over a different Rom i used before, i followed ROM or Kernel-UpdateROM instruction, everything works fine except i keep getting "Sorry! The process com.android.phone has stopped unexpectedly..please try again." jump continuously on myscreen
Hope somebody help me out thank U!!!
First off did you do a full wipe of all your partitions cache, boot, data, system, and then to advanced and wipe delvike cache before flashing your new ROM?
Also did you do at least two soft resets after flashing your new ROM?
As posted above, if you have not done so I would suggest a full wipe and re-flash. Sounds like something went wrong during the flash, or your partitions are wrong.
I've had this problem before, so again, full wipe and re-flash according to the instructions by the dev and let us know.

Try the "Wipe data/factory reset" option and the other options you listed before and then reflash the ROM. Then report back.
oh thank u very much..it's working

[Q] When someones says "wipe memory/reset"

When it's mentioned to wipe memory/factory reset before loading ROM is this the procedure they are referring to?
Thanks -
no.
Since you have to flash the rom from Clockwork Recovery, you will want to do the wipe from there also.
In Clockwork Recovery, you would scroll down and choose "Wipe Data/Factory Reset".
No. Just no
U can also wipedata/factory reset via stock recovery... This is incase u bootloop, somtimes wiping data from stock recov will fix this when wiping from cwm wont...
Boot into stock recovery by turningoff phone (or pulling batt if in bootloop), turn on phone by holding home+power, when android and ! Come up hit search button, select wipe data/factory reset, reboot phone... This method will also get rid of rom fragments left behind

[Q] Delete Data

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.

[Q] Need help with CWM 5.0.2.6, need screenshots or menu list

Hi
Can anyone pm me screenshots of menus in Clockwork mod recovery 5.0.2.6 ? My HTC HD2 was not showing anything on boot up screen (no tricolor menu, no visible clk letters or cwm menus, just screen is a bit backlighted) but after some time android boots up and screen works fine. I presume my LCD is almost dead, but I'd like to get to recovery, delete dalvik, format cache partitions etc, repartition sdhc card and try to reinstall hyperdroid. I found few videos on Youtube but is nothing about advanced menu. If someone could post some screenshots of all menus or write down menus structure I would try to wipe everything and reinstall rom to see if it still works before spending money on new lcd. Thanks for help
Okay, first, to get to the recovery .. Hold the Home button for about 8 seconds.
Here is the menu :
1- reboot system now
2- apply update from sdcard
3- wipe data/factory reset
4- wipe cache partition
5- install zip from sdcard
6- backup and restore
7- mounts and storage
8- advanced
9- power off
To delete the dalvik .. press the volume down seven times (option #8: advanced) .. and this is its menu :
1- reboot recovery
2- wipe dalvik cache
3- wipe battery stats
4- report error
5- key test
6- show log
7- partition sd card
8- fix permission
so you need to go down once (option #2: wipe dalvik cache) hit call.. then wait for about 15 seconds (for yes/no to show up) then hit call again to confirm.
I recommend partitioning your sd card from your pc.
To install hyperdroid ..
Go into recovery (repeat first thing) then go down four times (option #5: install zip from sd card) .. hit call, then hit call again to (choose zip from sdcard) .. then hit call (assuming you have nothing on your sdcard but the ROM) .. and then hit call again to install.
I hope you get your LCD fixed
Thanks a lot !!! It worked, even managed to create partition in cwm. its almost good phone again. Almost, becouse its still backlighted during bootup, but when android loads up - its fine. But now question is... why LCD doesnt work in first phase of boot up, but it works perfect when android is loaded ? Any ideas ?
I've found video on Youtube :
www*youtube*com/watch?v=0KEyuVrFxQI
(change * into . as I cant post links)
My phone behaves exactly the same during boot.
I bought it second hand, had WM6.5 for 3 months, than Android from SD for about 1 month and then nand hyperdroid. Never had any problems with unexpected freezing, reboots.... anything. my sdhc card is 16gb sandisk class4, 1gb ext3 partition done in cwm, 0 swap, clk 1.4.0.1 150/5 (with 120/5 was the same) just typical settings as tutorials says is it LCD dying or something ? Thanks ...
Maybe it's a problem with HSPL ? if you could reflash it and see if anything changes.
I, myself, used to (and still) flash a lot of different ROMs, bootloaders. And now, everytime I want to flash something, the "HTC" logo no longer shows up .. I only see the progress bar, However, the phone is working fine.

[Question] What does it mean to "WIPE"?

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.
cheers
