EPE54B (new N1- AT&T) -> FRF50 -> FRF83 & beyond (hopefully) in 20 minutes
and FROYO IS AWESOME !!! Believe me , it's really worth making this effort .
Ok guys , I think it's time for me to contribute some documentation for the XDA forum. As mentioned in the Topic's header , I moved to Froyo y'day night and wanted to share the process with the AT&T N1 ppl on the forum who are ready to unlock the bootloader but are lazy/frightened to go about the so-called lengthy process.
I am a new N1 & a new android user (just a month old ) who has spent sleepless nights like some of the people in this forum and most of the people (here) waiting for the Froyo OTA to hit their N1's. After a 3 week sleep disorder I finally went in for the kill. Thanks to Paul for his guide and others in the forum because of which,this it was accomplished in just 20 minutes.
AT&T N1 (EPE54B) owners who are bold enough to unlock their boot loader ... here's the way to glory.
Senior XDA members please correct the process if you feel something is not right.
I will be using most of the info provided by Paul in his post (here) and I hope he wouldn't mind , if I use his info.And believe me guys , it seriously takes only 20 minutes.
DISCLAIMER
1) I do not take credit for any of the stuff posted here. It's mostly from Paul's guide and other sources. All credits go to the original up-loaders.
2) This is a step-by-step guide which I have prepared from the process I have followed to reach FROYO and am not responsible if it doesn't work for you.
2)You agree that by doing this process, I'm not responsible for any bricked devices.
Unlocking the bootloader will void your warranty.
This process will erase all of your phone's data.
INITIAL SETUP
1) Download android-sdk_r06-windows.zip
2) Unzip to C:\ drive so it looks like C:\android-sdk-windows\
3) Run SDK Setup.exe
4) In the screen that pops out - Double click everything so it has a red X except for green check mark next to "USB Driver Package"
( which means just have to install the USB Driver)
5) On you Nexus 1 - Navigate to 'Settings -> Application -> Development -> enable USB debugging'.
6) Connect your nexus one to the computer through the USB cable provided with your phone.
7) Wait for the PC to install the device driver.
- If it doesn't then --- 'New Hardware Found -> Point the install location to C:\android-sdk-windows\usb_driver\'
8) Once the driver is found and installed ; On your computer open a command window. 'start -> Run -> type 'cmd' -> hit 'ENTER'.
9) On the command screen: Type "cd c\" ; Hit 'ENTER' key
10) Then Type: "cd C:\android-sdk-windows\tools" ; Hit 'ENTER' key
11) Type: adb devices ; Hit 'ENTER' key
- It should say something similar to "HT123P123456 device" (this is your phone's serial number).
- If it says "cannot find" or "invalid path" etc, make sure you're typing *exactly* what the green text above says.
- If it says something else, try to reinstall the USB Driver package and restart your PC.
12) If it works, your PC is correctly recognizing the phone. Continue on to the next step!
UNLOCK BOOTLOADER
1) Turn off your nexus one.
2) Press and hold the trackball and also press the power button ( while still holding the trackball pressed).
3) A white screen with three droids at the bottom appears.
4) A RED background highlights "FATSBOOT" which changes to "FASTBOOT USB" in a second or two.
5) Now, On your computer open a command window. 'start -> Run -> type 'cmd' -> hit 'ENTER'.
6) On the command screen: Type "cd c\" ; Hit 'ENTER' key
7) Then Type: "cd C:\android-sdk-windows\tools" ; Hit 'ENTER' key
8) Now on your computer; TYPE: fastboot devices
- It should say something similar to "HT123P123456 fastboot" (this is your phone's serial number). If it doesn't say this, something is wrong.
- If you are typing fastboot devices and it just returns a blank line or ???????? (ie Windows 7 64-bit users), try using USB drivers in the PdaNet install:
http://www.junefabrics.com/android/download.php
9) If it shows the device number , then you are set to go.
10) On the command window opened previously ; TYPE: fastboot oem unlock
11) Read the screen carefully. If you click on unlock it will wipe all your DATA!! and also Unlock your phone .
12) Use the volume control keys on your nexus one to switch options and then press the power key to select the option.
13) An "unlocked padlock" appears while booting and YAY!! you are unlocked!!!!
14) Shut down your phone and boot into the boot loader ( Trackball pressed + power button )
INSTALL(FLASH) RECOVERY
1) Download the latest Amon_RA's recovery img from here
2) move it to "C:\android-sdk-windows\tools" .
3) On your computer open a command window. 'start -> Run -> type 'cmd' -> hit 'ENTER'.
4) On the command screen: Type "cd c\" ; Hit 'ENTER' key
5) Then Type: "cd C:\android-sdk-windows\tools" ; Hit 'ENTER' key
6) On you computer's command window -- Type: fastboot devices and make sure your device's number is showing up.
7) On you computer's command window -- Type: fastboot flash recovery recovery-RA-nexus-v1.7.0.img
8) It should say: sending 'recovery' (3962 KB)... OKAY . . . . . writing 'recovery'... OKAY This should take a few seconds.
9) If flashing the recovery was successful, use the menu options to boot directly into recovery, or restart your phone normally.(without going to the bootloader screen).
Rooting
1) Download the nexus-addon-0.1-signed.zip from here.
2) Copy the file onto your SD card. ( It should be in the root folder of your SD card i.e don't put it under any directories).
3) Shut down your nexus one
4) Boot into the boot loader ( Trackball pressed + power button )
5) Press the power button once ( quickly and for a very short time ).
6) The screen changes and you move to the Fastboot screen.
7) Do Not do anything for about 8-10 seconds. It scans for some files and returns to the "FastBoot Screen"
8) Now use the "volume down" button to select "Recovery" and press the power button.
9) Do this step only if you didn't use Superboot: Use trackball -> "Flash zip from from sdcard" -> nexus-addon-0.1-signed.zip
- If you get a Triangle with a ! in the middle alongside an Android for 5+ minutes, you MAY have to remove battery and re-flash recovery (I had to do this once.) (Make absolutely sure that nothing is happening on your phone, as removing the battery when it's doing something can cause a brick.)
- Alternatively, try the optional Superboot method, and then re-flash Amon_RA's recovery image.
10) Select Reboot.
Phew .. that was hard ... but here comes the best part !!!
INSTALL FRF50 with Radio
1) Download the FRF50 with Radio zip file from here (Paul's FRF50 ROM).
2) Copy the file onto your SD card. ( It should be in the root folder of your SD card i.e don't put it under any directories).
3) Rename it to update.zip and make sure it's not "update.zip.zip". ( if you have the extension names off ).
4) Shut down your nexus one.
5) Boot into the boot loader ( Trackball pressed + power button )
6) Press the power button once ( quickly and for a very short time ).
7) The screen changes and you move to the Fastboot screen.
8) Do Not do anything for about 8-10 seconds. It scans for some files and returns to the "FastBoot Screen"
9) Now use the "volume down" button to select "Recovery" and press the power button.

15) You get an "install completed" message after about 15-20 seconds.
16) Reboot and you are into the wonderful world of "FROYO".
FRF50 -> FRF83
1) Ok, now I think you are already enjoying your delicious dessert. Let's add some strawberries to it.
2) Download the PAUL modified FRF50 -> FRF83 zip file from HERE.
3) Connect your phone to the USB cable and mount the card.
4) Remove the existing update.zip file from the SDcard.

15) VOILA , you are on the latest and greatest android update for Nexus one.!!!!
I think I'll wait, but excellent work on putting all of that together!
Thanks for the step by step. I believe another approach is to not root (just unlock the bootloader) and to flash back to the TMO ROM and use the leaked official updates. I'm trying to determine which to do.

As far as the info goes from this forum .. I came to know that unlocking the bootloader will void warranty. SO I felt that it's worth rooting the phone after unlocking it as we have advantages like Titanium backup and a lot more ...
I did a similar procedure, flashing my phone to ERE54B--->ERE27-->FRF50-->FRF83
I unlocked the bootloader/rooted in the process, but in the end I end.. I installed FRF50--FRF83 to my unrooted nexus one on ATT.
I wish I had tried applying the ERE27 original ROM to my phone with a locked bootloader, I don't know if it would of worked or not.
Either way, I am an ATT Nexus one on FRF83. It's quite nice
Nice instructions, good job compiling!
However, there is no need to flash FRF50 first, and then FRF83. You can just flash Paul's FRF83, and the radio separately.
AvengerBB, a prerequisite of Amon_RA's recovery image is a rooted phone. I am not sure exactly why it requires root, though.

It wouldn't have.
Just to clarify for me..
I understand unlocking bootloader is what 'voids' your warranty is required to root. It is also not possible to 'undo'.
Is having a 'rooted' phone what prevents you from getting OTA updates, or is having an unlocked bootloader?
If you have a phone with an unlocked bootloader, but not rooted... does google/android OS know any different? (Not warranty claims, but for S/W updates)?
Basically, if/when the ERE54B-->2.2 Update goes official, can I flash back to ERE54B and get the 'original' upgrade intended for my phone if I unroot it. Or will I from here on out have to manually update my phone?
Would you guys PLEASE take a look at this and tell me if you are having this trouble too!
nice work, very well documented, glad someone did this. Thank you.
I think I will continue to wait out the official OTA, but if I get antsy this weekend I know where to come for instructions.
stick this thread!
I have a rooted and bootloader unlocked AT&T version nexus one and I have already installed the FRF50 WITHOUT the radio. Should I go back and reinstall FRF50 with the radio before upgrading to FRF83? On by current build the phone sometimes doesn't reconnect to AT&T service once it has lost service and I need to restart the phone. Does Paul's FRF50 ROM have a radio that supports AT&T? Kinda a noob, sorry. Thanks in advance for the help.

You need to flash the newer 12_7 radio. The radio image remains the same for ATnT or T-mobile, the actual frequencies are decided by hardware. No need to re-flash FRF50 - just flash the new radio from here - http://n0rp.chemlab.org/android/nexus/radio-4.06.00.12_7.img
You can use "fastboot flash radio radio...img" command to flash it. After flashing new radio, flash FRF83. It is highly recommended that you flash only compatible OS and radio versions.
Man
I have followed all the steps but when I go to flash the update from the sdcard it gives me the an error that says there is no signature and install aborted. What could this be from? I have tried those steps again and again. Please help.

You can't re-lock the bootloader without being very lucky, you need an S-OFF SPL. Just having an unlocked bootloader won't effect your ability to get OTA updates, it's custom ROMs and recoveries that do that.
If you're going through all that trouble, just use Paul's superboot to FRF83.
Finally got it to work! It didn't fix my video recording bug though. When I switch from camera to video it just freezes and reboots. Did they ever find a workaround for this? I would appreciate the help.
Shouldn't need a work around, mine doesn't suffer from it.

Arent you guys facing troubles with this radio?
My gps is innacurate... i think that is because of the radio image!
If with the oficial froyo it does not is fixed i will flash back my 4.04 radio!
Take a look at this to read about my trouble please!
Need some help. Everything worked up to this point.

I didn't get an "install completed" message. Instead it says, "Reboot via vol-up+vol-down or menu to complete installation." Then when I reboot it goes to the android falling out of the box image, and then boots back into recovery. I can restore with the nand backup just fine, but this method doesn't seem to work for me. I believe it's the damn radio upgrade that is causing the problems because right before the reboot it says "Writing radio image...". Anybody else experienced this?

Have you tried doing "Reboot phone" after it boots back into recovery?
how to factory restore the tab...i saw many flashing guides bt the problem is i downloa the firmware files...bt dont know where are the other files like PDA, CSC and PHONE files....plz asap...
To check your version of these files just type *#1234# in a dialer
what i mean is whn i try to flash...in the guides i saw that i have to put phone csc n pda files also...bt i got only the firmware file...i dont have these files...so where can i download them??
my system files are
PDA DDJK3
PHONE DDJJ1
CSC DDJJ1
If all you want to do is perform a Factory Restore then all you need do is either go to Settings/Privacy and where it says Personal Data select 'Factory Data Reset', or with your phone switched Off put the phone into Recovery Mode using the two button press method.
Press and hold both the Volume Up & Power button. After a brief period you should then see a menu appear with options. Now using the volume up/down keys select from the options 'Factory Restore and hit the power button'.
Your Tab will then be restored.
Well i tried that...bt the problem is i have rooted tab n i deleted many system apps which r creating for my tab now...so i want a complete firmware restore...i read guides so i think i have to flash it now...bt i m nt able to finds proper guides for it...they say in Odin first i have to select .pit file thn phone pda n csc files,..so my question is where ill get this files?
Hello all,
Im having trouble with a newly acquired my touch. I bought it with stock 1.6 on it and it has upgrade to stock 2.2. Its not rooted. The OTA downloaded and installed. The problem now is the phone keeps restarting. It loads all the way to home screen and then freezes and just restarts. I tried going to recovery but same thing it loads recovery and just freezes. Xda members are the most knowledgeable about this. What can I do? Can I downgrade or anything? I cant do factory wipe because it freezes before I get a chance to do it.any help is appreciated!
What all your fastboot info?

If your sure that recovery isn't working your going to have to downgrade. I know I've put directions on how to do it somewhere, but I've got to dig them up. I need to know if you still want to upgrade to the 2.2.1 OTA or if you just want to re-root.
I actually didn't have root at all. Everything's stock. I'm not sure why that happened. Maybe a bad flash? I don't want to do 2.2.1 OTA, it's really slow! Thanks for your help. i just want this phone to function again like normal.
Sweetness.
1. Go here and download "sappimg.nbh", "update1.zip", "update2.zip", "Gio's_OTA_Froyo-1.8.1.zip", and "Universal Androot.apk".
2. Copy the "sappimg.nbh", "update1.zip", and "Universal Androot" to your SD card. Once on your SD card, rename "update1.zip" to "update.zip".
3. Boot into hboot (volume down+power), it'll pick up the sappimg, do a file check, then ask you to hit "Action" to continue, press the trackball. It'll run the updates and ask you to press the trackball again to reboot.
4. Once you get to the Google Activation screen, just shut the phone off.
5. Boot into recovery (home+power), you'll get a triangle with an exclamation mark and a phone, hit home+power again to pull up the menu. Select "Apply update.zip from SD card". It should automatically pickup the update, run it, and reboot. Once again, do step #4.
6. Put the SD card into the computer, delete the "update.zip" and "sappimg.zip" files from it. Move "update2.zip" to the SD card and rename it "update.zip. Also move the "Gio's_OTA_Froyo-1.8.1.zip" file but don't rename it, just put it on there.
7. Do step 5 again for the second update.
8. When you get back to the activation screen, sign-in. Go to market and download/install "Appinstaller". Open the app and select the Universal Androot.apk. Install it as well, then open it and click root. When it says you've got root, download/install ROM Manager from the market. Select "Flash ClockWorkMod Recovery", then scroll down and select "Flash Alternate Recovery".
9. Reboot into recovery again (it'll look different than before), go to the wipe option and select "Wipe data/factory reset", "Wipe cache", and then "Wipe dalvik-cache". Hit home after each one to confirm.
10. Select the "Flash ZIP from SD card" option. Select the "Gio's_OTA_Froyo-1.8.1.zip" and hit home to confirm. When it finishes flashing, reboot, and welcome to awesomeness.
Let me know how it goes. If you have problems let me know on here or hit me up on Google Talk at [email protected].
Thanks a lot for the very detailed instructions! I had a question. since i dont have a data plan on this line, do I need someone with a data plan to actually activate the phone?
Thanks DonJuan692006! Your post helped me as well.
this method was successful for me in Puerto Rico. first thing we have to do is take root. once done root, down lock away apk region. apply it and then run it. t you going to ask you if you want to reboot, you give to reboot later. you enter the service mode * # 001 #, once in the menu, you hit the menu button and give it back, then menu key and enter the letter (Q) capitalized on key imput. enter new mind a menu and key imput, you give it 4 times (0000) and wait a few seconds until you take umts menu. walk to (1) umts, then (6) common, then (6) nv rebuild and finally, (4) restore backup. phone will reboot and you will have unlocked. 4GLTE running straight talk. sorry for my English as I use google translator

26.now ur phone will restart and in my case it didnt unlock my carrier. what a bummer but fear not we shall continue..
27. Now you have to root this phone, iv downloaded kingoroot for this..use whatever method u like to root ur phone.
28.now assuming ur phone is rooted, download regionlockaway follow this link http://forum.xda-developers.com/showthread.php?t=2470551 or http://forum.xda-developers.com/attachment.php?attachmentid=2370437&d=1383564029
29.now copy regionlock to ur phone using usb cable..should be easy ,use file manager on ur phone, install it, requires root access..click accept, launch the app, click on regionlock
30.it will say updating modem, finally it will show patch seems to be successful.blah blah blah ..choose reboot now and thats it your done!
31.if u dont see ur carrier, go to settings, connections tab, more networks, mobile networks..choose ur carrier, wait for it to register and finally ur done
Note:u can update ur modem to new version because the unlock is permanent, changing firmware or baseband will not lock the phone ENJOY

9.the latest ODin has BL, AP, CP etc
10.now lets do this! Choose AP and Load ur stock 4.4.2 firmware, odin will sometime say not responding but dont worry after a moment it will finish loading..check the logs on the left. also make sure autoreboot is check and reset time..these option are checked by default. DONOT TICK OTHER OPTIONS..JUST DONT.
11.Once loaded, click Start and Odin on top left will show you a progress bar on how much until done..this will take sometime..sit back and relax
12.once done, your phone will restart and start loading the new firmware, if stuck on samsung bootlogo continue to step 13 if not skip to step 15
13.Remove your battery and put it back on and hold power button + volume up to enter recovery mode.
14.Once you see recovery mode, scroll down using volume down, select reset cache/factory setting, press power button to select, scroll down again on YES an click power button to select, once done, go to main menu and select reboot system
15. Ok wait patiently for ur phone to load the firmware, once loaded..skip the user setting as much as possible..like setting user acc,time and date etc...
16.go to settings, more, scroll down, select about device,check os version..should be 4.4.2
17. now scroll down more and see build number..tap on that a few times until its says ur now developer.
18.tap back, in settings menu, you will now see developer options, enter developer options and check usb debugging
19.Now the tricky part, we will now change the baseband to get several option unlock in the service menu..mainly to get this option PERSO SHA256 OFF in the service menu. if most of u have upgraded to 5.01 firmware and tried every unlock method..but not working..This method works 100%.
20.Assuming all drivers working perfecty, usb debugging On, turn phone off and go to download mode, hold power button+volume down, select volume up to continue
21.now ur in download mode again, Download I9505XXUAME2 which can be found in this link http://forum.xda-developers.com/showthread.php?t=2192025 and extract the zip file to a folder.
22.Launch ODin (run as ADministrator), make sure ur phone is added!, select CP and select I9505_XXUAME2_MODEM.tar.md5 and click start,when finished ur phone will restart
23. Almost there! , so now go to settings,more, about device,check baseband, should say I9505XXUAME2, if so ur good to go
24.now u can check this http://gs4.wonderhowto.com/how-to/c...y-s4-so-you-can-use-another-sim-card-0148110/ to see how to get to service menu
25.i will tell u anyways..go to dialer, type *#0011#, touch menu on phone, select key input, type 1 (sometimes i type Q0 if 1 doesnt work), press ok, press menu again, press back in menu..wait until u get the service menu, go debug screen, phone control, network lock, and there it is! the damn PERSO SHA256 OFF.click on that, u can continue to follow the guide in the link with photos where its says go back to main menu and go COMMOn, nv rebuild, restore backup..do that too.
26.now ur phone will restart and in my case it didnt unlock my carrier. what a bummer but fear not we shall continue..
27. Now you have to root this phone, iv downloaded kingoroot for this..use whatever method u like to root ur phone.
28.now assuming ur phone is rooted, download regionlockaway follow this link http://forum.xda-developers.com/showthread.php?t=2470551 or http://forum.xda-developers.com/attachment.php?attachmentid=2370437&d=1383564029
29.now copy regionlock to ur phone using usb cable..should be easy ,use file manager on ur phone, install it, requires root access..click accept, launch the app, click on regionlock
30.it will say updating modem, finally it will show patch seems to be successful.blah blah blah ..choose reboot now and thats it your done!
31.if u dont see ur carrier, go to settings, connections tab, more networks, mobile networks..choose ur carrier, wait for it to register and finally ur done
Note:u can update ur modem to new version because the unlock is permanent, changing firmware or baseband will not lock the phone ENJOY
