Buddies,
can anyone upload the original roms for Milestone XT720? (SG, Kr, and other)
So we can do more testing worry free. If anything goes wrong, we can just flash it back to original. It would be nicer if someone can also show how to flash the rom.

Flashing Guide by Hahutzy

Alright, I just crashed my phone into an infinite FC loop by messing with system/app, so a reflash was in order.
Here's how I successfully flashed it back to stock using Windows 7 32bit (dense text ahead):
1) Search somewhere along the lines of "RSDLite - download here" on google
2) Go inside first link, download the file that's named somewhere along the lines of "RSDLite_4.5.3.zip"
3) Install it.
4) Go to http://and-developers.com/sbf:xt720
5) Download the 2nd Full Flash rom, the one where the provider is "Southeast Asia"
6) Unzip that file, you now have a .sbf folder (not file)
7) Put that .sbf folder in C:\Users\Admin\My Documents
8) Shut down phone, take out battery
9) Hold Power + Volume Down + Camera buttons all at once
10) Put in the battery while holding those buttons
11) Phone is now in bootloader mode (screen looks like a command prompt)
12) Release the buttons, and plug USB to computer and phone
13) Open RSD Lite, your phone should be detected as connected (Device name was like "S OMAP 3440" or some BS like that)
14) Click "..." to browse for the .sbf file in C:\Users\Admin\My Documents
15) In RSD Lite, click to highlight your connected XT720, and then click "Start". The first column beside the connected phone should now have a green icon thing, and the ROM is being flashed.
16) DO NOT TOUCH YOUR PHONE, THE CABLE, OR THE COMPUTER! (I went and took a dump)
17) When the "Status" column in RSD Lite says "Please manually power up this phone", so shut it down and power it again. Note: The status stays in "Checksum Group 37" for a verrrrryyyy long time before saying "Rebooting". I thought it got stuck there, but it ended up ok.
18) Your XT720 is now reflashed to stock.
19) You can now close RSD Lite. It will complain saying you will damage the attached device, but I pulled it out wayyyy before this (I unhooked it when it told me to reboot manually) and my XT720 is not dead. You may choose to close RSD Lite before unhooking your XT720.
20) Post your results in this thread and confirm or reject my procedure.
spiderx_mm, you may quote this on your first post for others' easy access to this procedure if you so wish to.

Sorry, can i know how to put the phone into bootloader mode? I cant not find in google and this forum for xt720.
press volume and power together
can not go to boot loader. Already press power and volume button
first you need to switch off the phone, then press camera button and power and keep those pressed until recovery icon appears. THEN press volume up and power, if I remember this correctly.

Hi, I'm a newbie. I want to upgrade the OS of my GT540 phone from Android 1.6 to 2.1 but I'm not sure what to do. I read some posts but some of the technical terms like fastboot and rooting are new to me. I already downloaded the drivers and kdz files. Help please?

1.get your phone and if its on turn it off. hold power button and camera button until the lg logo goes and screen is black
2.download black system.7z and extract to your desktop
3.and run flash.cmd as administrator then plug in your phone whilst its screen is black.

5.the phone will automatically reboot when finished. it may take long to reboot but its not like that normally, its just got a lot to load.

how to use clockworks recovery
when phone is off, press and hold power and home button to switch on in clockworks recovery mode.
to scroll up or down use volume buttons.
to select press call button.
to cancel or go back press end call button.
DONT DO THIS
If you follow this, and flash with fastboot rom, you cannot flash anymore with original rom.
For now I suggest that you flash with original rom only.
So my buddy was going through his files and may have possibly deleted an important file (update.zip) from when I rooted his phone. I able to get into initial part of recovery (1. reboot system 2.apply update.zip 3. wipe system 4. wipe cache) but when I click apply update.zip I get failed to verify whole_file signature, instiallation aborted. Any ideas?

this should be in general
however what file are you trying to flash? if its a ROM, redownload it and click choose zip and choose the file not the "update.zip" choice

I'm not trying to flash a rom. I'm actually trying to just get it to boot up fully. I'm not in clockwork recovery. I'm at the menus when you power on the phone while holding the home button
EDIT: I usually don't post questions, I'm usually good about fixing them before having to come here for help.

haha, thanks homie. I've been looking up this sbf stuff I've been looking up pretty much states that I need to put the phone is PC mode (mass storage) and enable debbuging bridge, which I'm unable to do since I can't actually get the phone out of android system recovery.
NOTE: I CANNOT get out of system recovery. Which means I can't access bootstrap, any homescreen functions (PC mode, Debug bridge, etc...) and also unable to push any files to any part of the system files via. command.

Thank you,
Just a little note 4.7 works just as well as 4.8 and 4.9. Just thought I'd point that out
While I appreciate the help, this phone is pretty much done for until I get a new battery, will not charge high enough to sbf it.
RDS lite isn't showing my device, help plz? got all the proper files, but unable to get usb bridge going since I can't get into the main OS
You don't need USB bridge, sbf mode has it's own set of drivers that may or may not need to be downloaded manually. Try plugging it in and then going into device manager and making sure it's being recognized, if it shows up as a yellow question mark, you need to install the drivers manually.
Success. Thanx for the help guys. My buddy's phone is in working order again. One last question...is it safe for a reroot?
Does anyone knwo where i can locate the files for the stock update to froyo 2.2 I have search high and low but in the one reseounce i found it had 2 files but the second file download was broken link.
Quoted below i just need the second file if anyone could help.
Download this file:
http://android.clients.google.com/packages/ota/tmobile_opal/894fb8631db9.hboot-1.33.0013.opal.zip
That is the HBOOT image and is the first part of the patch. Download and save that on your computer. Next download this:
http://android.clients.google.com/packages/ota/tmobile_opal/e3671133717d.signed-opal-FRG83-from-DMD6...
That is the second part of the update and is the actual update to Froyo. Download that and save that on your computer.
Next, just to be sure, BACK UP ALL YOUR DATA and make sure you know all your passwords! Do a factory reset on your phone.
Once that's done and you're back into your phone, copy the first file you downloaded (the HBOOT image file) to your SD card on the phone in the root directory of the SD card (not inside any subfolder), and rename it to update.zip. Make sure you name it update.zip not anything else or it won't work.
Turn your phone off.
Hold down the Home key and the power button and hold them both down while the phone powers up until you see a screen that has a yellow triangle with an exclamation point in it and a picture of the phone next to it. Once you see that screen, press Home and power once again. This will bring you to the recovery screen. You will see an option that says Apply update.zip from SD card. Use the trackball to scroll down to it and click it. It will then install the HBOOT update. The phone will reboot a few times during the process. Don't interrupt it! Once it's done, it'll boot back into the 1.6 desktop. Part 1 of the update is now complete!
Now delete the previous update.zip file from earlier in the process from the SD card. Now, copy the 2nd file you downloaded to the SD card in the root directory and rename it update.zip.
Turn off your phone.
Hold down the Home key and the power button and hold them both down while the phone powers up until you see a screen that has a yellow triangle with an exclamation point in it and a picture of the phone next to it. Once you see that screen, press Home and power once again. This will bring you to the recovery screen. You will see an option that says Apply update.zip from SD card. Use the trackball to scroll down to it and click it. It will then install the actual Froyo update. Again, the phone will reboot several times during the process. Don't interrupt it! Once it's done, it'll boot back up and you will now be running Froyo!
I recommend also doing another factory reset after the phone is fully updated... just to be sure (it's what I did). Enjoy, everyone!

Did you find the 2nd file?
Did you ever find the 2nd file? I am having a hell of a time trying to find this as well... If you found it, please let me know! Thanks.
EDIT: So I found the update. It was under the developer threads in the mytouch area: http://forum.xda-developers.com/showthread.php?t=659403
http://www.4shared.com/file/j64ygA9t/RUU_Sapphire_T-Mobile_US_31253.html
My Nexus One is rooted (I forgot how I did it).
Last night suddenly my phone went off and could not reboot anymore. It stayed on "X" screen forever. I tried to hard reset (i.e. Pressing volume down and power button). Then I pressed "Recovery" and then it went restart and stayed on "X" screen forever again. What can U do?
Please help, I am a new root user. please teach me step by step to do so. thanks.
Turn it off. Hold the trackball while starting it up. If you have usb debugging on and working fastboot drivers, you can wipe your phone (fastboot -a in cmd) and flash an img file of like a stock ROM.

I tried this already but still not work, I had brought my phone to some third party mobile repair centre, they said my N1 is CPU broken and will cost around US$96 to replace with a new CPU (HTC need around US$190 for mother board). I paid US$96 anyways. not sure if it worth.

The bootloader of my N1 is unlocked, I am not familiar with fastboot thing. My friend helped mine root and he is out of my country now. Gotta follow cnalbant's steps and see.
Install ClockworkMod Recovery on Nexus One Manually
Step 1: Download ClockworkMod Recovery: recovery-clockwork-2.5.1.1-passion.img (there are more current, look at the xda)
Step 2: Set up ADB for Nexus One
Step 3: Put the downloaded recovery-clockwork-2.5.1.1-passion.img in C: drive
Step 4: Turn Nexus One off and connect it to PC via USB
Step 5: Hold the Power button + Trackball together to start Nexus One in fastboot mode
Step 6: Once in fastboot mode, open Terminal / Command Prompt and run following command:
fastboot devices
This command will check if your device is connected in fastboot mode or not.
Step 7: Now run following command (place the file recovery in the same folder where the fastboot):
fastboot flash recovery recovery-clockwork-2.5.1.1-passion.img
This will install Clockwork recovery on your Nexus One.
That’s it, enjoy!
You can either follow the above guide or this amon ra recovery guide
forum.xda-developers.com/wiki/HTC_Nexus_One/Recovery_Images
Amon ra is another recovery just like clock workmod
B4 using adb download the drivers of adb and fastboot
www.mediafire.com/?bhxmn903d6cz9eg
When you connect ur phone use device manager to locate the connection on win 7 and select install drivers frm folder and install frm the extracted folder of adb driver
