Hard reset =/= restoring all the system files?

I am using Touch HD (BlackStone), I installed one of the hot fix from HTC and it seems causing my phone lock up with the ICR program. I did hard reset and reinstall the ICR and it still crashing all the time. I spended 2 days playing around with countless hard reset and the problem was still there. Finally I flashed my ROM and the problem seem gone now. Seems like the hot fix replaced some of the system files and the hard reset didn't restored them.
I just wondering what exactly hard reset does? Does it just delete the extra files and settings installed by users without restoring all the system files?

a hard reset restore all files of your phone (delete all contacts, messages, settings, programs....) to original parameters.
It's like a "fomat c:" for a computer !

So when I flash the ROM image into the phone, it will put it in a protected area in the flash ROM and hard reset will copy all the files from there to another portion of the flash ROM and execute from there?

when you flash a rom, it erase (or replace, it's the same) the 'older' rom !
a hard reset just delete all files ! if you hard reset your phone, it will be like you buy it, when you power on your phone at the first time !
there is no multi-partitions, one and only one OS can be flash, install and run at the same time !
I hope it's clear, and I answer your question, because my english is very bad....

Hey, if you try format c: ,you get rid of ALL datas on your disk, including OS !! So, it´s not like hard-reset Hard-reseting deletes all user-made data, but it doesn´t do anything with ROM/firmware files, so if you changed them, you can get them back only by reinstalling OS ;-)

Ah that explain why hard reset didn't fix my problems but re-flash the same ROM into phone did.
So there is a list of files in ROM to tell the hard reset program which are needed to keep?
thanks

sorry, it's to hard for me to explain what I think in english

[Q] accidentally deleted files

sorry for my question but wanted to know if anyone can help, 7 days ago bought a acer stream, I made the root and then exploring delete files by mistake apk system, of course, many things do not work now. If anyone can help they would appreciate a lot. Thanks.

You're pretty much out of luck. If you deleted the files 7 days ago, they are likely un-recoverable. If they are on the sd card, and less than a day or so, you have a chance to recover them using GetDataBack.
Your best bet is to do a factory reset to get all the files back.

remove them from the system and are apk files, there is no method to revive my acer?, it means that I throw it, only serves, I can not load a new rom?

thanks
these are the files I needed but when I try to run with the browser gets me close to applied force and will not let me run it. There is some solution to this?

Factory reset the phone. If you cant do it via settings, try recovery menu.

all
I tried to start from the menu, I did restart buttons and no screen goes black and does not reset to factory settings with some other idea?

Hardware Reset nightmare

My tab developed problems and all got worse after I tried to update the Contacts.apk from a thread. I backed-up the original files and restored them but still nothing worked. I decided to do a full hardware reset but things only got dramatically worse.
Now the tab is basicall destroyed. I get crashes one after the next, cant use the phone, cant open contacts, all crashes again again.
Doesnt a full hardware reset recover all all stock apps in its place or not? I have no idea what to do at this point anymore
It seems whatever system files that were damaged are still there and worse... dont understand the mechanics of this... I thought a hardware reset meant THAT. But it just "looks" like all my custom apps and confirations were reset to original but all problems with system files are there and even worse than before. Have no clue what to do
I also tried with the system off the method of pressing and holding the “Volume Up” and “Power” buttons at the same time, then after recovery screen appears navigate and select “wipe data / Factory reset” and pressing the “Home” button, but after that and the system re-starts, same thing! All bad.
Can someone please help me? How can I restore all files and everything back into the Tab as originally shipped? OMG, what a nightmare....
Thanks in advance.

Once you mess with files in the root folders they are damaged for good. A master reset does wipe everything but it does not have some magical copy of all system files stashed away to overwrite, this is why the phones are rooted, to keep you from messing with these files. Your best bet would be to just flash the device and start from scratch. You could also just extract the contacts.apk from an appropriate rom and possibly copy it over from your sd to the unit using ADB.

Sorry, like he said, you will have to rebuild. But think of it as an opportunity to try a few new things.
Do you have a backup made by CWM3 when you installed your latest rom? You can restore it if you can get into recovery.

close to brick (coby 7015): how i got out of a pinch

Here is my story.
I found a patch that was supposed to give me ad-hoc on my coby 7015. i don't quite remember where i got it but i believe it was in the xda forums. well i'm not sure if it wasn't written correctly, was malicious, or if i didn't read the details correctly but i tried to install it. this also may have had a part in why things went south. I first tried to use the regular recovery util to install it since the zip was called update...w/e that didn't work. i then switched to clockworld recov to install and i used the apply update from sdcard setting...didn't look at when it was installing i just rebooted and kept moving ( i was at work and pressed for time).
when i realized my wifi wasn't working anymore i tried to install it again realizing maybe it was the way i did it, so it stead of the "apply" option, i used select zip to install. still the same problem...
after all this i decided the best thing to do would be to
1. see what was updated in the file: only thing i saw other than certs was the wpa_supplicant file
2. find an original version of said file and replace it: I did this via WinVista instead of terminal for couple of reason the primary being that i couldn't remember the command to copy/paste in linux and i wasn't sure if the terminal could extract and re-zip files.
so plugged into the laptop i pulled files and tried updating first in the regular again, then in clock world with similar results and the same problem.
Ieventually tried posting a question on the linux forums because it was quickest and i usually get fast answeres, however, i was impaitent so i ended up doing the most fatal part of this. I decided to do a factory reset.
I started with the main recovery util and used the reset:
1. i still had the same problems with wifi
2.ALL my APPS (including my emulator and root access, the most important of al my apps)
I then tried the UI factory reset and got nothing.
Becoming frustrated I tried really just a freak, last ditch attempt. used the coby update found on there site and it fixed the wifi. I am now lacking Gapps and my other apps but i can now get those back cuz i have wifi....whew

Fixing LG vortex bootloops

I recently had a problem on my LG vortex. I had rooted and deleted some bloatware, then because I was upgrading phones, I thought I might sell my vortex for cash. So I did a factory reset. Much to my dismay I shortly found out that I had accidentally deleted the home screen from the phones factory memory leaving me in a boot loop. even a hard reset using default recovery wasn't working. After a day or so of research I found a couple of guides:
LG vortex downgrade guide - many thanks to Salem, as much of my guide is copied from his
http://forum.xda-developers.com/showthread.php?t=883314
after a bit of tweaking I was able to recover the phone by following these steps:
Disclaimer: I am not responsible for *any* loss or damage (including bricking) to your device -- use this guide at your own risk!
[Setting up your computer]
if you previously downgraded your LG vortex from 2.2.1 to 2.2 chances are good this part is already done
1. download files from following links:
factory flashing software & firmware
optional free un-rar software
2. plug in your phone (even in it's crippled state) it should autorun, and install some USB drivers
3. extract LGNPST.rar and run the LGNPST_General_v1.2_Lab_Version.msi this will setup to the directory C:\LG Electronics
4. copy/move LGNPST.exe to C:\LG Electronics
5. extract the LGNPST_Components rar file, this will make a directory with two MSI files in it - run these.
6. Go to C:/LG Electronics/LGNPST/ and create a folder called “Model”. Inside that folder, create another folder called “LGVS660″.
7. Extract LGVS660.rar. Inside this, you’ll find a VRZ folder. There are three files inside this: a .tot file, a .scr file, and a .dll file. Move these all into C:/LG Electronics/LGNPST/Model/LGVS660/ (the folder you just made.
8. If you’re on Windows XP, hit start, click on “Run”, and run this:
regsvr32 "C:\LG Electronics\LGNPST\Model\LGVS660\VS660.dll"
If you’re on Windows Vistas or 7, hit start, type cmd.exe, right click on cmd.exe when it comes up in the search area, and run it as an administrator. Type in the following and hit enter:
regsvr32 "C:\LG Electronics\LGNPST\Model\LGVS660\VS660.dll"
[setup complete] your computer should now be ready to fix your phone
Contrary to popular opinion on the many forums I perused researching this, I found that this software does *NOT* require your phone to be in debugging mode! it will see your phone if you simply plug it in at this point
[Flashing the phone]
1. go to C:\LG Electronics
2. run lgnpst.exe
3. if you haven't already boot phone and connect USB if the phone was already connected disconnect and reconnect it to make sure the software recognizes it.
Warning! do not disconnect your phone from the cable under ANY circumstances until the software tells you it's safe to do so!
4. try to directly flash phone back to factory. This will require you to select the .tot file from above under where the program is expecting a .bin file (you'll have to manually type in a filter in your file selection box) also select the .scr file in that same directory.
5. if that doesn't work go to the Data menu
6. select 'data recovery'
7. let that work it's magic and it should transfer to 'emergency mode'
8. select the .tot file and then the DLL for your phone
9. flash -- if everything works out your phone will reboot around 60% with everything on it
10. once the phone has booted completely go to menu and set phone to USB debug to stop the 'flashing' process this will allow you to safely disconnect your phone
ENJOY!!!
[emergency flashing]
*WARNING! the following methods are untested! above methods worked for my phone!*
Once again, do not disconnect the phone under ANY circumstances until the software tells you it's okay to do so!!
1. boot the phone in emergency mode by holding volume *up* and the back button at the same time (as I gather from the above mentioned xda post)
2. once in emergency mode it should be safe to continue from step 8. above.
[end guide]
Many thanks to those out there who helped me build this guide!! I hope it helps!! Now you should have the freedom to try removing all that bloat ware again. Hopefully, with a bit more discretion this time
In case anyone is wondering -- yes, I'm a n00b, and yes, this guide is for n00bs just like me

Advice?
Can this method be used to return a rooted/hacked/modified phone to FULL factory stock so you can return it for a warranty claim? IE- will it remove clockworkmod, superuser, and any other traces that you messed with the phone? Also, is this for verizon?
I had a lg vortex I had to return recently due to a blown speaker making my calls sound like a kazoo.
I DID root it (using gingerbreak)
I DID run some sketchy root programs like setcpu, wifikiller, root explorer, wifitether, and a few others
I originally ran ROM manager to backup my rom when I first rooted, but it said it installed clockworkmod (selected LG optimus V from the list and it worked) in order to run properly.
I have slowly uninstalled all of the software, used rom manager to restore my first backup, then uninstalled rom manager, installed gingerbreak, unrooted, uninstalled gingerbreak, uninstalled everything, then did factory reset from settings menu.
As of today the phone looks stock. No superuser. No sketchy programs, I'm just not sure if CWM or something else could have survived the factory wipe from the settings menu. I know superuser survives a factory wipe, so I'm not sure if I still have dirty files lying around. If verizon knows I rooted my phone it will cost me $309
Is that good enough? I don't want to return a device that has evidence files on it, but I have no clue if clockworkmod got uninstalled with rom manager or not. I never changed roms, I never knew how to boot into cwm, I don't know if it's still there or not. Advice?
EDIT: You should note that my phone is NOT bricked- the speaker is blown, so there should be no limit to the menus, functions, or software tweaks available which would be needed to fix my situation. Also it should be noted that I am not the type of person who condones returning a bricked phone to get another one- That hurts us all. Unbrick yourself using a thread like this or eat your mistakes.

hi, I recently rooted my phone with gingerbreak and uninstalled some bloatware from verizon. Then I couldn't see the home screen, although I can pulled down the status bar. After following your steps above and at running lgnpst.exe. I got the error message saying: Fail to load the Skin.dll. Do you have any idea? Thanks
