I am going to assume you already have a Nandroid backup created on your SD card using JF 1.31's recovery Alt-B feature. The backup will create a folder called nandroid on your SD.
What you need:
The Android SDK:
Fastboot Windows Binary in this post:http://forum.xda-developers.com/showpost.php?p=3083753&postcount=1
From your Nandroid backup you need three files:
data.img
system.img
boot.img
Steps to restore your phone
1) Put the files Adb and AdbWinApi.dll from the tools folder in the Android SDK into C:\WINDOWS\System32 folder on your PC. Substitute the correct drive letter if windows is not installed on you C: drive
2) Put the Windows Fastboot.exe into the C:\WINDOWS\System32 folder on your PC
3) Create a folder on the C: drive of your PC called android. The path should be C:\Android.
4) Copy the Nandroid backup files data.img, system.img, and boot.img from your SD card to the folder called Android you created by mounting your SD card as removable disk.
5) Unplug the USB cord and power off your phone
6) Power up your phone by holding CAMERA+POWER, you should see three androids on skateboards. If you don't see this go install the Engineering boot loader
7) Plug the USB cord back into your phone and press back. The screen on your phone should say fastboot.
8) Make sure your pc is using the correct driver. Open the device manager on your pc. It is helpfull to have all other USB storage devices besides your phone unplugged for this part. Look for a USB Mass Storage device in the list of the USB devices. Right click on it and update the driver. Pick the option to browse for a driver on your pc. The driver is located in the Android SDK your downloaded in the folder called usb_driver. If this is done right you will now see a device called HTC Dream
9) Press start, go to run and type cmd (If you are on Vista just type cmd in the search box and hit enter). The command prompt will pop up.
10) Type cd C:\android
then enter the following commands:
fastboot flash system system.img
it will say Sending, then writing and say OKAY if it was successful
then type
fastboot flash userdata data.img
wait for the second OKAY and type
fastboot flash boot boot.img
wait for the second OKAY and type
fastboot reboot
Your phone should now be restored exactly as you had it when it was backed up.

Flash Nandroid Image from the phone

Is there a way to flash a nandroid back up image from the phone itself? My computer has been acting up and I'm unable to use fastboot at this point.

I would love to know this as well. I think JF mentioned that he was going to include that option (flash nand backup) in the recovery console but I dont think I've seen anything else about it.

I think the recovery "Flash nand backup" option is already there. Make sure you have HardSPL installed first though.

Step by step for the n00bs?

JF's allows you to create NAND backups from the phone.
Just boot in Recovery (Hold home and power)
hit alt-b to back up
hit back and home to reboot
AFAIK, you need to use fastboot on a computer to flash the backups back onto the phone.
the commands are:
(must have fastboot installed on system path folder OR the folder you will be working out of)
Have the Data.img, boot.img, and system.img copied from SD to a folder on HD
Boot holding camera and power (need to see skating androids)
connect USB
hit back to see Serial0 instead of fastboot (if not, you need to properly connect the device in device manager ie don't mount it!)
then open a command prompt to the folder where the imgs are
type:
fastboot flash boot boot.img
fastboot flash userdata data.img
fastboot flash system system.img
then reboot the device. Should be good to go

i think they mean to flash it from the phone with no computer... i could be wrong but im sure thats what they are asking

I have posted to the nandroid folder by for some reason when I do a back up and then try and restore it says all went well but when it reboots it gets stuck on the T-Mobile G1 screen. I have tried a fresh build of JF R33 and tried to back it up and then restore thinking it could be something I have installed but even a fresh install with out adding any apps does the same thing. If anybody has suggestions on how I can do a back up and restore with out it locking up.
Paul

I don't think that you can restore with a nandbackup as of yet. Maybe I'm wrong though. There is an easier way actually... if by chance you don't have access to a computer and get stuck with a looping android or boot screen or whatever (because of a bad update.zip, theme or whatever) I carry a spare 512mb sd card in my wallet. On this card I have a fresh update.zip (RC33) on it. So I just swap the cards out and do an update from there just like that. No problem at all.
OR
You can have it on your current SD card but just use scripts to do your updates. Granted it's a little more time consuming... but you have less risk of messing something up later on. Just don't delete your RC33 backup.
It also helps to have GScript to store the scripts in.
Here are examples of a script:
echo "boot-recovery
--update_package=SDCARD:themes/Aero/update.zip" > /cache/recovery/command
reboot recovery

Click to collapse
echo "boot-recovery
--update_package=SDCARD:RC33/JFRC33/update.zip" > /cache/recovery/command

Click to collapse
Or you can even do this:
echo "boot-recovery
--update_package=SDCARD:/Haykuro/V45.zip" > /cache/recovery/command
reboot recovery

I think it's a lot easier then moving files around all the time and forgetting what that 8mb file is on your sdcard later on.

Randum, you are correct
I could be a noob but I can search and I can find the obvious (i.e. how to flash back images from PC) so I wouldn't ask for that. I thought someone actually found a way to do it all from the phone (which would be so nice, I don't have enough clearance to install my own stuff on the PC at work so I have to do stuff from the phone). Oh well....
Thank you all for the effort though, very nice that someone actually took time to write it out, at least for others who did not know how to do it from PC.

[GUIDE] Rooting and flashing your patched Hero. (Windows) [Updated: 12/19]

Constructive criticism is welcome.
This is my first guide and it's quite late here so I'm going to go through this lightly first, and more in detail later.
Note: I am NOT responsible for any damage your phone may or may not receive. It is your fault for following this guide, not my fault for writing it. Just for the sake of saving you from a headache, I would recommend backing up your contacts before starting this guide.
Phase 1: Prepping your CDMA Hero for rooting/flashing.
1. Ensure that USB debugging and installing apps from unknown sources is enabled. You can do this by going into Settings> Applications Check unknown sources. From there go into Development and ensure that "Enable USB debugging" is checked.
2. Mount your SD card on your computer by plugging in the USB cable, and dragging down the notification area. BACKUP YOUR DATA! ALWAYS!
3. After your data is backed up, Safely remove hardware (I find it annoying to get the "this disk may contains errors" every time i plug it in) your Hero. Using your notification area, unmount your SD card.
4. On your hero, navigate to Settings> SD card and phone storage> unmount SD card. Then format your card. It should Auto re-mount after this.
5. Download FlashRec (great tool!) and Amon-RA's recovery image. Place them onto the root of your SD card (not in any folders, just drag and drop them.) Unmount your SDcard.
6. I used Linda File manager (from the market), but you can use one of your choice. Navigate to the root of your SDcard (you'll probably start there, if you dont just click sdcard.) Open flashrec with the installer, and wait until it's finished.
7. Open FlashRec, and attempt to make a backup (i simply named mine "/sdcard/backup"). If it success proceed to the next step. if not, refer to post 2.
8. In FlashRec, type "/sdcard/recovery-RA-heroc-v1.5.2.img" without the quotes. Linux is Case-sensitive, so the capital letters have to be included. tap "download recovery image". Wait for it to finish, when it does reboot into recovery mode by powering off your phone. After it's off, hold HOME and the power button. You should see some green text on a black background.
9. First things first, Make a nandroid backup. It can, and will save your ass at some point in time. Before you flash ANYTHING to your phone, ALWAYS do a nandroid backup. Congratulations, you can now flash a custom ROM!
Phase 2:Flashing your custom ROM
Since I love Flipz and his work so much I'll be using his ROM in my guide (let me know if you have a problem with it Flipz).
0. Do a nandroid backup before you even think about downloading a ROM
1. Download Fresh 1.0.
2. Do not unzip it, leave it as it is and copy it to the root of your SD card. You can do this either from recovery mode (by enabling usb mode) or through the notification bar. Proceed to recovery mode by holding HOME+END CALL (or just disable USB mode) and select "flash update from .zip" Select the Fresh ROM and wait. It should automatically reboot after it finishes installing.
3. Be patient while it's booting, it took me about 5 minutes for the first boot, after that it gets much faster. Once it loads, everything should be all fine and dandy. If it's not, well aren't you glad you made your backup? Just proceed back into recovery and do a nandroid restore.
4. You can now delete all those .apks and .zips and whatnot. Mount your SD card on the computer, and move your backed up files back onto your card.
5: Enjoy! If you don't like the clear lock, Flipz has a patch on his website (geekfor.me) to replace it with a clear screen. This should keep all of your contacts and settings in place, but I make no promises.

The Unlockr

How to unpatch your Sprint CDMA Hero.
Phase 1: Installing the SDK/Drivers
1. Download the SDK from Google. Create a folder at the root of your C:\ drive called android (it doesn't have to be your C:\, you can put it anywhere, but this guide will use "C:\android" as it's path.)
2. If using Windows Vista or earlier, proceed to the next step.
3. Download the driver for your system.
Windows 7 32Bit
Windows 7 64bit
To find out which drivers are right for your system, go into your control panel, and change the view type to small icons. Click on system, and check and see if it says 64-bit Operating System or 32-bit Operating System. Extract the contents into:
C:\Program Files (x86)\HTC\HTC Driver\Driver Files\Vista_x64 (for the Windows 7 64-bit)
or
C:\Program Files (x86)\HTC\HTC Driver\Driver Files\Vista_x86 (for the Windows 7 32-bit)
4. If you have not plugged your Hero into the computer yet, it's as simple as navigating to where you extracted the contents of the archive, and right clicking androidusb.INF (should be the second from the top) and clicking install.
5. Ensure that USB debugging is enabled by navigating to Settings>Applications>Devolopment. If it does not have a check next to it, tap it. Plug your phone in and wait for the drivers to install.
6. In Windows, navigate to the command prompt.
XP: Start>run type "cmd" and press enter.
Vista or later: Start/"orb" in the search box right above it, type "cmd" and press enter.
if you see a window pop up with "C:\Windows\system32\cmd.exe" if you have done this correctly.
7. type "cd \android\tools" and press enter. now type "adb devices". It should start a daemon, and show you a series of numbers. If it does, then congratulations! your drivers are installed properly! I'll come back and add later how to reinstall the drivers if they do not install correctly.
Phase 2: Unpatching your Hero
Ensure that you have an adaptor to plug your SDcard into your computer. I didn't use an adaptor when i did this, but I highly recomend it just to make things easier. If your phone or SDcard or computer or toaster blows up, catches fire, shoots lazer beams and burns your curtains, or causes any damage to your or anything else I take no responsibility.
1. Backup all of the data from your memory card onto your computer. Navigate to Settings> SD and phone storage. Unmount your SD card and format it.
2. Go to Settings> Applications> Devolopment and ensure USB debugging is enabled.
3. Open command prompt, as you did in Phase 1, and navigate to "C:\android\tools". Type "adb shell" and press enter. Now you're in your phones console. Type "cat /sys/class/mmc_host/mmc1/mmc1:*/cid"
4. Copy down the code you get EXACTLY. Double, triple, and qraduple check. If the code is wrong, you may destroy your SD card.
5. Reverse the code.
Example:
123456789
Would become
987654321
6. replace the first two numbers/letters with zero zero. (007654321). Now on your PC, navigate to Here. Copy the number (with the zeros in place!) to the box that says CID. Click continue and wait for the email with your goldcard key. Save it to your computer.
7. Download this hex editor and install it. run it (requires administrative priveledges), and put your SDcard into your computer, or mount your SDcard.
8. In the hex editor, click on the extra tab, and open both your SDcard and the Goldcard you downloaded earlier. Ensure that "Open as read only" is unchecked when you open your SDcard. Sector size should be at "512 (Hard Disks/Floppy Disks)".
9. Go to the Goldcard tab, and press Ctrl+A to highlight all of it, then press Ctrl+C to copy it. Go to your SDcard tab, and select from 00000000 to 00000170. Now click on the edit>paste write.
10. click File>save. Remove and replace your SDcard, or unmount and remount your phone. If you can navigate into the drive, congratulations you have a Goldcard.
Phase 3: Downgrading your Hero.
1. Download the1.29 RUU. Plug your phone into the USB port with your goldcard inserted. Have your phone powered on when you do this, and ensure that it is not locked.
2. Ensure that you have HTC Sync installed, and that it connects to your phone.
3. Run the RUU and wait for it to finish. After it is finished, proceed to post 1.

If we simply want to upgrade to a different ROM or the new 1.5.2 recovery.img then can we simply pick up on your instructions from that point??
Thanks for your post. The only thing I think you are missing (for a totally new user doing this) is explaining how to boot into recovery mode when you are ready to flash the new ROM.
There is one other thing that I think would be great to have added to a post like this and that is an explanation of how to restore your programs after flashing a new ROM. Do you just reinstall them or is there a way to restore files and be able to keep your screen looking mostly the same?

Whats up with the Moto Droid? When are ROMS going to be pushed? and are you going to wright and Guide for Droid like this one?

As far as I know, you just have to reinstall your programs. This guide will also work for loading ROMs other then Freshhh, but some ROMs require you to do a wipe before you install them. Check to see if that specific ROM requires a wipe before doing an install. Yes, I have used this method to upgrade from RA's 1.2.3 to 1.5.2 with no problems.

I have no idea about Droid modding, as I don't have a Droid. I'm not to fond of the idea of writing a guide for a phone I don't have because I wouldn't be able to verify that it works with minimal problems.

Alright, I've completed the basics of how to do this. I'll add a problems and solutions section once people start having problems.

great job, this should help folks out a good deal.

That's my intention. Just trying to make things easier for those who aren't so good with the console. I think I'm gonna go ahead and do the Win7 driver workaround now.

In step 8 of the guide I can follow along up to step 8 but when I type in the text I don't see the download option.

You're talking about the FlashRec step right?
Could you tell me exactly what you can see?

So this is probably an obvious question, but I apparently not to me, but is the guide to perform a downgrade for people who have not rooted and flashed their phone? Because I was able to downgrade to 1.29 ruu after having flashed my phone with Fresh 1.0, is it because I flashed a custom rom that I could downgrade to 1.29 or is there something different now?

This is a guide to try and simplify patching, but it also covers a section on how to downgrade a phone that Sprint/HTC patched so that the 1.29 RUU method wouldn't work.

How does someone get a phone that was patched by sprint/htc to not allow the 1.29ruu to work on the phone?

Excellent work! I just want to let you know that the link for the RUU 1.29 does not work (at least for me). Great guide though.

Link updated.

[Q] How bad did I brick my Kyros 7005??

Okay, where to start.. I think I have bricked my phone pretty good.
Here is the approximate list of things that happened.
I wanted to try to update to froyo, so I downloaded z4root, worked beautifully
Followed all the directions to install clockwork mod (including reading far enough ahead to find out the one in the directions was for the 7015, but gave the link for the 7005 version later) - Worked like a charm
BACKED UP SYSTEM as instructed
Then here is where things went south. I attempted to install the Cyanogen Mod froyo based. I followed the directions, including backing up softmac and wpa_supplicant files. And it would not start up. I could get it into recovery mode but not to start fully. I tried doing the restore, it couldn't mount the SD Card where the backup was. Being knowledgeable enough to dangerous in Linux, I used ADB Shell and tried various things to try to find out where the SD Card or recovery image failed. I had also been trying to locate FWDN as I saw people had done fixes with that, but I couldn't get it to load in FWDN "Mode". I figured if I could replace the recovery program on there that doesn't work with the one that does, it should in theory allow me to reboot into the correct recovery mode and let me pull the files from my SD Card. After about 15 minutes of shuffling around, I ended up mounting the \system folder where I found a file called recovery. Looked to be the right size. So I made a modified batch file that would instruct it to load from that folder.
After that mistake, all of the sudden, the vtc driver that I had installed did see the unit. I was like Joy! Joy! I fired up fwdn but since I didn't have the original files that it "liked" I used an lk.rom, but I think it wasn't from an X5A but from a lonpad. Now I don't even get COBY on the screen.
But wait, I'm even more dangerous. I got the hardware ID that it's currently using on the USB bus, edited first the vtc ini file to see if I can reload a different rom. It detects it, but FWDN gives me "bad boot" error or something like that. But I'm a trooper, if I'm gonna kill it, I'm gonna kill it good. I change the SDK/ADB driver to recognize the device. And it seems to recognize it. Then I went to try "fastboot flash recovery recovery.x5ag.img " which I had NEVER been able get the unit into fastboot mode, and it goes through and does it. Then I do a fastboot reboot to see if I can get it to come up in recovery mode, but I can't.
Then the final bright idea comes up on me.. Hey, I have the backup from SD card, what if I zip it up, call it update.zip, and do a fastboot update?
Now ADB can make some kind of connection to it, but when I try to shell I get:
- exec '/system/bin/sh' failed: No such file or directory (2) -
ADB State always reports device or unknown never bootloader
ADB remount comes back with remount failed: Invalid argument
ADB push into the / or /system folders (in an attempt to push a copy of sh there) fails saying read only file system
ADB push to /sys comes back with failed to copy: No such file or directory
So, that's where I am.. I think I really really REALLY bricked this thing... although the fact that I can still ADB to it leaves some shimmer of hope.
Thanks,
Joe

can u get into the boot loader at all? If so you are not Bricked you will just need to reinstall the entire system using fast boot. You may be able to restore the default OS using an update.zip file. It may be named something different for your device. All you do with that is place it on the root of the SD card and when the bootloader boots it finds the file and flashes the phone.

I can't get fastboot to recognize the device, it goes right to the ADB bridge. Where I can run some limited ADB commands that are recognized.. If I could get it to start up in fastboot mode, that would likely solve the issue, provided I can get the correct working update.zip file, rather than me trying to fudge one from the clockworkmod backup.

do you have any hardware buttons on device? turning on with volume up or down (or back) gives you differing USB ID's to device manager - obviously you want fastboot mode. (use device manager on ADB Bridge (Details) to get your ID - i think its DEED for fastboot and D00D for fwdn)
otherwise... you can force boot a new bootrom. It's what I did on my telechips device. Find tcboot.rom - put it in the same directory as fwdn
1. Open your device
2. Unsolder your battery + terminal
3. While turning on the device, place a short - screwdriver/pin etc - across pins 7/8 of the NAND chip (for 5 seconds)
4. FWDN should bring up a message about flashing bootrom
5. Reboot (and resolder battery cable)
Note: this obviously is pretty hardcore - but i went from brick, to black screen brick, to full restore via this method.

[Q] My phone bricked. Need help please..

My phone is unlocked and rooted. My problem is that when I go to FASTBOOT MODE, then go into RECOVERY, then when I press 'apply update from /sdcard' it shows nothing in there. So, I just stuck and unable to flash any rom at all. I tried to go into the SD card through my computer to install a ROM so that I have something to flash, but nexus s has only internal storage. Please help?

Hi
Hi, I bought my nexus s, immediately after I tried to root, and failed, this left me in the same situation as you.
You NEED to install the adb drivers, and boot using odin files. It was pretty tricky but i got there in the end, i was bricking it too , but dont worry, there's a 98% chance its not bricked, ill find the files for you now...

Go to mount drives and mount your storage from there. That's what I did.

Right, first of all, boot into the bootloader on your Nexus S, and i'm assuming that all your drivers are working fine because you have already unlocked your bootloader.
Place the files in the zip download inthe following places
WIN32bitOS: Program files/Android/Android-sdk/tools
WIN64bitOS: Program files (x86)/Android/Android-sdk/tools
Next, open a command prompt, and type in the following commands, (C: is your windows installation hard drive letter, leave as default if you dont know what this means)
if your 32bit type this w/o quotes "cd C:/Program files/Android/Android-sdk/tools
64bit "cd C:/Program files (x86)/Android/Android-sdk/tools
and click enter.
Next you want to make sure that your Nexus S is in bootloader mode, connected to your pc.
Type the following.
fastboot flash boot boot.img
[click enter & wait until it says successful]
fastboot flash recovery recovery.img
[click enter & wait until it says successful]
fastboot flash system system.img
[click enter & wait until it says successful]
fastboot flash userdata userdata.img
[click enter & wait until it says successful]
Reboot and you should go into android 2.3
Next time make a nandroid backup in clockwork mod!

hi cdaly, can you point me to some information on how to install nandriod backup and making/restore a backup right after installing CWM (right after "unlocked" but didnt install Super user yet)?

Yeah
Yeah sure,
Root your phone, go to market place, download rom manager. Open the app and click the button that says, Fash Clockwork Recovery.
Shut down your phone when the operation has completed. Go inot bootloader mode, click recovery. Navigate to backup and restore. Go into backup and restore, click backup. Voila.
If you ever need to restore do the same but click restore. Pretty simple when you know what to do
If this has left you confused, look around on XDA/google, there are a ton of guides
Link added!

Thanks, appreciate it.

Thanks for that. I am using mac computer. Would it be the same typing command for mac as you had mentioned?

I got to the point flash recovery was sucessfuly in command prompt, but when i try to install "su-2.3.6.1-cd-signed.zip" from SD card, it wasn't successful, as in there is no "superuser" icon after reboot and i have tried wifi tether and it says my phone is not root.
Now i havent tried "su-2.3.6.1-ef-signed.zip" because i accidently bricked my phone for some stupid things i did. but my phone is NOT root as long as I don't see the superuser program right?
I thought nandroid is an actual program but it just means backing up through bootloader?
Thanks for all your help!!!

I dont know if NANDROID is a program or not, it just use it via clockwork mod recovery menu and it works so I'm not complaining aha
If you want to root your nexus s, download this zip file and extract, make sure that your nexus s is in bootloader mode and double click "install-superboot-windows" Bingo, you have root.
Thanks for that. I am using mac computer. Would it be the same typing command for mac as you had mentioned?

It wouldn't hurt to try but I dont think so. If you can go into boot-camp or use a friends PC. Or you can try this.
Change your folder to the plaform-tools folder. I dont know how to do this, just referencing off of http://rootzwiki.com/wiki/index.php/Samsung_Nexus_S
Next type
"./fastboot flash boot boot.img"
"./fastboot flash recovery recovery.img"
"./fastboot flash system system.img"
"./fastboot flash userdata userdata.img"

Hi cdaly985
I'd tried it and it works 100%. And, just to share for mac to add on the command "./fastboot-mac ....". I am really impressed with your help. Thanks very very very much.

Hi cdaly985
Now everything is ok with the phone except that it won't be able to go into recovery mode. I had tried by using Rom manager v.4.. and also by pressing vol + power, all failed.
Please help me on this problem. Thanks.
