Hi again Paul, I just got back to the office and got it to take the image and then got into the recovery mode and updated the system to the Cyanogen Mod 5 latest update and it downloaded it and the phone said it installed and asked if I wanted to reboot which I did. When it boots up it just stays on the pretty little startup screen with all the colors and it stayed on that screen for about 40 minutes.

So I pulled the battery and rebooted and it still is hung on the startup screen. What do I do next?

I booted it into the recovery mode to see if that still worked and it does and I went to restore and it gave me an error and told me to do a something something mobile restore.

I'm Stumped. I will go in now and see if the computer recognizes it as a device.
[Nexus One Android Development] sandyturley:
I clicked on toggle/usb in the menue and then got into the sdcard so I can access that still.

But when I reboot it just goes to the annimated google X with all the pretty colors.
[Nexus One Android Development] sandyturley:
Paul should I wipe it and start over with the cyano Mod install?
[Nexus One Android Development] sandyturley:
Oops I forgot to answer you. Yes when I boot holding down the tracker ball and i get the white fastboot screen.
[Nexus One Android Development] 24bronco:
These are the exact same steps and problems Im having. my computer is windows xp. also Thanks in advance for help Paul. I cant wait to get Sense on my N1
[Nexus One Android Development] Paul22000:
Hmm, that's very very weird. When you unlocked the bootloader, was it able to boot into Android ok? And did it have the padlock at the bottom during boot?
[Nexus One Android Development] 24bronco:
When I unlocked Bootloader I was able to boot into android fine. and yes it had the padlock (unlocked symbol). all my info was gone and it should the welcome and setup screens.
[Nexus One Android Development] Paul22000:
If you made a Nand Backup, then yes. That's the beauty of the backup, you can always undo anything. : )

Backup -> Wipe -> Reflash Cyan Mod

Let me know how it goes.

For anyone else that's having any problems, if you've made a Nand Backup when it was working, then feel free to wipe wipe wipe. Reflash and see if it helps.

BTW, how did you fix the "cannot load 'recovery-RA-nexus-v1.6.0.img' "? You left a cliffhanger there on one post, and your next post in the office it was working. What did you do? : )
[Nexus One Android Development] Bunk:
I also had the "android out of the box" problem after flashing the recovery rom (bear version).

That was at work (XP). I went home, started a virtual XP machine on my Macbook Pro, downloaded the normal recovery version (without the prety bear ;) ) and it worked after 2 tries. (Flash, reboot, error, pulled battery and tried again)

After that the recovery rom booted fine and I could continue flashing the Sense rom.

hope this will help others...
[Nexus One Android Development] surmanm:
same here booted into android fine, and the padlock is unlocked...all info gone went to welcome screen phone works fine... is their an alternative way to boot the recovery image file am i missing something..??

thanks again for all your help

I Figured out my problems as to why I could not get the Flash recovery on my N1. apparently it needs Superboot. http://xdaforums.com/showthread.php?t=611829&highlight=triangle&page=24

I followed this thread and also this thread http://android.modaco.com/content/g...superboot-rooting-the-nexus-one/#entry1142739

and got it working. after installing superboot I was able to load recovery-RA-nexus-v1.6.0-carebear.img, hope this helps as I just spent about 8 hours panicing and researching.
[Nexus One Android Development] Paul22000:
Hmm, I didn't install superboot when I did it.

Might be something good to try for others I suppose.

(I did install the OTA update manually a few weeks ago however.)
[Nexus One Android Development] karnovaran:
I'm getting the ! in the Triangle issue too. I re-flashed 3 times with the first img then 3 more times with the carebear version. I'm trying superboot, but it just hangs at "sending 'boot' (2164 KB)..." I've double-checked that USB debugging is enabled. Using XP as well.

Stumped.
[Nexus One Android Development] Paul22000:
Can you try rebooting your PC and re-trying it?

Can not Flash into recovery

See my Post about my issue with booting into recovery mode. I tried your steps below and received the following:

- If it still doesn't work, reply to this thread and say "adb devices does not work.

Step 3 of SDK setup. I double click SDK Setup.exe and receive error message: Failed to fetch URL SORRY I'm new user I can not post links, reason: HTTPS SSL error. You might want to force download through HTTP in the settings.

I continue on and open up CDM prompt and am only able to type in C:\android-sdk-windows. I can not get cd C:\android-sdk-windows\tools to appear. What could be wrong.

My PC is running _Windows 7. I have a Nexus 1 Rooted and Froyo 2.2
[Nexus One Android Development] Kiserai:
When you launch SDK Setup.exe and it gives you that error, just cancel out until you get to the main window that says Android SDK and AVD Manager.

Click on Settings to the left side and there's an option under Misc that says "Force https:// to be downloaded..." Check that box, then go Installed Packages and hit Update All.

After that download what you want (just make sure you get the USB drivers and the Android SDK Tools) and you should be able to get past the error you're having.

If you still can't get it to show up using ADB devices, go into Windows 7 Device Manager and manually update the driver to the one in the android-sdk-windows folder. You might want to reboot after this step.

If that doesn't work, point a wooden stick at it and try some spells from a Harry Potter book, because you've reached the limit of my expertise. :)

When you did the "Flash Recovery", what did it say?
[Nexus One Android Development] dunn0w:
Recovery-RA-nexus-v1.7.0.1.img

Sending recovery OKAY

Writing recovery OKAY

Finisched total time 2.068s
[Nexus One Android Development] Paul22000:
What happens when you root after that?
[Nexus One Android Development] dunn0w:
The problem is the screen, i have SLCD.. not Amoled.

Something with the drivers.. so i have to wait till there is a recovery with good driver for SLCD
[Nexus One Android Development] Paul22000:
Oh. Wow. I hadn't even thought of that. Ouch.
[Nexus One Android Development] dunn0w:
No problem!

I got a new recovery img Amon Ra made for Slcd and now i can get into the Recovery modus YES finaly! :D

After flashing a rom, i still got the screen black.. ( driver problem:confused:)

I then flashed another kernel, now i got my phone working but with the Stock version frf91 with some tweaks.. i still cant flash it with a custom rom still got the black screen.

So i think al the roms that will come out need to have the right drivers to support Slcd.. Am i right? :rolleyes:

srry bout my bad Englisch (I try to learn :) )
[Nexus One Android Development] Paul22000:
Wow, that's great news. Awesome

Yeah all custom ROMs will probably have to be updated for SLCD. Maybe ask @Cyanogen on Twitter (www.twitter.com/cyanogen) if he can put it in his ROM.
[Nexus One Android Development] nakedwarrior:
I tried to plug my phone into the computer via usb and it didn't detect the phone or prompt for connection? Is there a setting I need to turn on, am I missing something or was this fixed in the previous versions? Sorry for a dumb question.
[Nexus One Android Development] orestisg:
Sorry if I'm off topic, just one simple question.

Flashing a new kernel has the same procedure as flashing a custom rom? Nandroid-flash-wipe cache?

I'm on cyanogen rc2 and I want to test evil's. Never messed with kernel before.

Thank u in advance!
[Nexus One Android Development] Paul22000:
@nakedwarrior: It should automatically pop up a New Hardware Found Wizard etc. If not, go into the Device Manager manually and look for an unrecognized device or for an android device and install the drivers manually.

@orestisg To be honest, I'm not sure. I haven't installed a custom kernel. But most of the custom kernel threads have instructions on how to do it, or they may have specific instructions for the kernel so it's best to ask in the thread to make sure.
[Nexus One Android Development] Worsty:
It's the same method of flashing but there's no need to wipe cache.
[Nexus One Android Development] incredulous:
I am stuck lol.

I think I know what the problem is but have no way of fixing it.

I have just got my Nexus one. Came with FroYo and I have unlocked the bootloader. I cannot however flash the recovery.

I think it is because of FroYo, how the hell can I sort this!
[Nexus One Android Development] Paul22000:
You're in the wrong folder. It looks like you're in the C:\ drive but trying to run something in the F:\ drive. Remember you should be typing only the green text of the guide, and exactly like it is written. :cool: Try typing "F:" first.
[Nexus One Android Development] incredulous:
Ignore the drive letters, I don't use C for anything apart from crucial drivers. All my applications run from D and extra downloads like films and stuff are on F.

The drive letters are correct. I've sussed that I have a Nexus One with SLCD and stock FroYo.
[Nexus One Android Development] Paul22000:
Ah, interesting. Second person to state this so far.

I added a note about SLCD Nexus Ones in the guide. Thanks.
[Nexus One Android Development] incredulous:
No worries Paul.

Respected sir,

as per your instructions i done my N1 with Htc sense (andriod 2.1).

But, I want to update now my N1 in Andriod 2.2

How ?

ANd I thanks to you.

You are a great.:D
[Nexus One Android Development] elikookoo:
first thank you for the great guide

but i did every thing you said and the nexus doesnt work

i power it up and its stuck on the google logo screen

like in stage 8 in the guide

[i canat post links cuz my acount is new..]

any 1 knows what can i do?

thank you again
[Nexus One Android Development] Paul22000:
Did you recently buy your N1?

It could be an SLCD screen, which needs special versions of the recovery and rom.
[Nexus One Android Development] bmwron:
When I tried to flash the recovery file, nothing happens.. I get sending 'recovery' (3962 KB) I wait and wait and nothing happens. I've waited as long as 25 minutes and I have done it more than 6 or 7 times. I've also tried the Superboot method and got the same thing after I run the batch file. Oh yeah, someone told me about the Gold Card method. I used a different SD card using the Gold Card method. Yet again.. I am still not able to get pass the flash recovery. I am using the Nexus 1 and it's unlocked because I get the unlocked padlock upon boot up.

Can anyone offer any help? Thanks
[Nexus One Android Development] Paul22000:
Is your N1 fairly new? Perhaps you have an SLCD screen rather than an AMOLED screen. Try the SLCD recovery

Does this work on G2?

Hi there,

Great instructions!!

I am not a developer, but I want an HTC phone, with physical keyboard and froyo. So I was thinking the G2. But I also want Sense UI. Will these instructions also work on the G2? Do I end up rooting the device by doing this? (I also want to root it anyway.)

Lastly, I want to unlock this phone so I can use other sims in other countries. Does this process unlock the G2 as well?

Thanks a ton!

[Nexus One Android Development] Paul22000:
I'm fairly sure this wouldn't work on the G2.

Hi Paul22000,

Can you please explain Network Bands for me?

I got a phone that's

Network Bands HSPA/WCDMA: 900/2100 MHz GSM: 850/900/1800/1900 MHz

and the provider uses HSPA/WCDMA: 850/1900 MHz

what does that mean? This is hardware that can't be changed?

Thanks in advance
[Nexus One Android Development] Paul22000:
Here are some great pages that explain this way better than I ever could:

http://en.wikipedia.org/wiki/UMTS_frequency_bands

http://en.wikipedia.org/wiki/GSM_frequency_bands

http://en.wikipedia.org/wiki/Cellular_frequencies

And yes, they cannot be changed for your phone.

Thank you Paul22000! Your advise is always trusted. There are so much information out there and so many people giving advise, hard to figure out who to trust.

hi paul2200,

new to the nexus and just recieved a 2nd hand one which the previous owner installed stock froyo 2.2 on it

can i still follow your guide on Page 1 for unlocking the bootloader/rooting/recovery image installing ?

much thanks

Chris :)
[Nexus One Android Development] Paul22000:
I think it should work as long as you don't have a Nexus One with an SLCD screen rather than an AMOLED screen, in which case you'll have to get different files (check out AMON_RA's recovery image for SLCD phones in his thread).
[Nexus One Android Development] dornestic:
Now to update radio, I have to double check because this will brick my phone from what I've read if done improperly. I've gone through the procedure that you posted OP, and I'm up to finished the nandbackup, now to flash the ROM.

But I have to flash the radio first, slow progressing.

Going through your instructions, i should follow everything under "FASTBOOT" steps right?

As in, which of these two options should i flash my radio under?

or

UPDATE: it's option two, through fastboot, for future reference.

Everything went smoothly, thanks OP!
[Nexus One Android Development] somebarryguy:
Hi, I know I am late to the party here but I am trying to download the Sense UI on the N1 and I am looking for some help:

Now its been a while since OP put up his guide so I am using a couple of different things, first I flashed with recovery-RA-nexus-v2.0.0.img since I couldn't find 1.7, and I believe I have a SLCD screen which v2.0.0 supports.

So I move onto "Do this step only if you didn't use Superboot: Use trackball -> "Flash zip from from sdcard" -> nexus-addon-0.1-signed.zip"

Now this is where I run into a problem, I get the error message "corrupt file: boot.img"

Again I know I am late to this but any help would be appreciated.

Thank you.
[Nexus One Android Development] Paul22000:
Possibly the file was corrupt during the download. Try re-downloading. Otherwise, maybe there is a newer version
[Nexus One Android Development] somebarryguy:
I just noticed the (Android 2.1) in the title o.O

I am running 2.2.1, I am going to assume this is why its not working out for me?

And yes, I will re-download.

Thank you
[Nexus One Android Development] somebarryguy:
Ok so I re-downloaded as you recommended, went into recovery -> Flash zip from from sdcard -> nexus-addon-0.1-signed.zip

This time it worked,

So I move onto the next step, I wiped all data and dalvik-cache and finally I move onto "Flash zip from sdcard -> alpha-r##-update-modacocustomrom-nexusone-desire-withadditions-signed.zip"

I am using r24-nexusone-desire-modacustomrom-withadditions-signed.zip because it is the latest version I could find. It continues with the process and I reboot the system and I get an Android falling out of the box and it boots back into recovery.

Again I restore/wipe and flash the ROM again but no avail.

I am almost convinced it is because I am running 2.2.1 (if so is there something I must do differently?)

Any advice is appreciated

Thank you again.
[Nexus One Android Development] Paul22000:
Most likely that is the reason. See if he has a 2.2 version available. Otherwise try another ROM like CyanogenMod just to make sure it's the ROM that's the issue, and not anything else.

[Nexus One Android Development] Paul22000:
It looks like your SDK didn't setup fully, as there are a few missing files, one of which of course is "adb".

Try re-setting up the SDK or re-downloading until adb is there.

Or maybe "adb" got put somewhere else on your PC; try doing a windows search for it.
[Nexus One Android Development] GHOST99K:
doesnt every sdk come with the adb in the tools? any suggestions on which sdk package to download and what to install from the sdk?
[Nexus One Android Development] Paul22000:
Not sure what happened. Did you run the setup and tell it to download the proper files? (Step II)
[Nexus One Android Development] GHOST99K:
i see the latest SDK android-sdk_r08-windows.zip(starter package) doesnt include ADB in tools.ill try another old package from your guide II. what are you referring to in "download the proper file"?
[Nexus One Android Development] Paul22000:
adb isn't in the zip. It comes after running the setup.

Are you doing this step? I'm guessing you've been skipping this part.

ok just downloaded the same SDK again.in the set up there is no USB drive,so i left all checks on and now installing it again.

No idea what could cause that. It might be because you have an SLCD N1 maybe. I'd make a new thread on the forums.
