[Q] Reviving my N1

Back when 2.2 first rolled out OTA I've had issues with my phone, it's been dead
It's not rooted or unlocked, was waiting for 2.2 to do all that
when the OTA came up, I had the phone install it
never booted up fully, would stick at the flashing Nexus logo till it locked up completely
now it can't get past the static Nexus logo at all
when attached to my PC it will not show up in ADB devices
I can get into recovery and the bootloader and it can access files on the SD card
what can I do to get something loaded on it so I can root it and move on with a custom ROM?
At one point I did have a file that loaded called PASSIMG that reset the phone to original shipping, but for the life of my I can't find it again, if I can get a hold of that file be it 2.1 or 2.2 based I can do what I need, or are there any other options?

http://shipped-roms.com/shipped/Pas...le_WWE_2.16.1700.1_FRG33_MFG_Shipment_ROM.zip
Extract the .zip from it, rename to passimg.zip, put it on the root of your SD card, boot into HBOOT and you should be back in business, it will OTA itself up to 2.2.2 in no time.

Read my signature, find there "Unroot/restore" guide.

Something's not right, I have the file in the SD card, boots into HBOOT
Reads the SD card,this step is fairly fast, then does nothing else
This has me intrigued now.
Tried two different files, it is extracted and named PASSIMG.zip
Not sure what else to do

Double check the file isn't named passimg.zip.zip common thing.
Or if you can't be arsed fiddling, unlock bootloader, extract the system.img and boot.img files from the passimg, and use fastboot to flash them.
Ps. You have tried to wipe it since it broke, right?

You don't need to extract anything. Just try to actually read the guide carefully and execute step-by-step, before posting additional questions.

Thanks Jack_R1 finally got it sorta working, it flashed the file over fine but is now stuck on the static Nexus logo for close to 20 minutes and seems to be doing nothing, gonna try again with an older ROM instead of FRG33, which one did it ship with originally?

Stuck on static Nexus logo - might be a faulty SD card, for example.
FRG33 should definitely work, the older that worked would be FRF91, but you won't be able to flash it using PASSIMG once you have flashed the FRG33 - it won't allow to downgrade.
If you can get to recovery (power off, press and hold trackball, power on) - perform a factory reset, remove the SD card, and try to boot again. If it doesn't work - you might consider making things easier on yourself and using fastboot oem unlock.

Not the SD card, works fine on my other phone
Can't unlock, phone not showing when doing a ADB Devices
Thinking it might be bad memory on the phone

To use adb, you have to be able to boot the phone to some level, and you may not be getting there...
Boot into bootloader, switch to the fastboot screen, then try fastboot devices.
You need fastboot to oem unlock, anyway, not adb (if you're planning on taking that route).
Sent from my Nexus One using XDA App

You use fastboot to unlock, not ADB

Yep, got it going now, not sure why I assumed that if it wasn't coming up under ADB, that fastboot would not work.

grats!
It 's alive! :d

Can someone help me get back into recovery?

Hi
I have been using Clockwork recovery for months and tonight was flashing ROM/zips as usual, and all of a sudden when I try to get into recovery my Nexus just sits on the colored X. When I pull the battery it reboots fine with the ROM I currently have installed. Then I go back into ROM manager, re-flash clockwork recovery: it says flash was successful, so then I choose to boot into recovery, and again it just sits at the blue, red, green and yellow X.
So then I tried a round-about way by going into ROM manager and choosing to restore a backup. Again, when I choose to restore backup it just boots to the colored X again and freezes there.
I've also tried the regular method of holding power button and trackball and get the same results.
Does anyone know why this might be happening? Right now I'm stuck with a ROM I was just playing with and didn't necessarily want to use permanently....I'm afraid I might be stuck with it forever now
Thanks for any help!!!

I've been searching and I should add that my bootloader is not unlocked

Try to flash your recovery manually, using the guide from my signature. Try Amon_RA's.

Well I ended up wiping all user data in fastboot and now I get nothing but an X nomatter what I do, won't boot at all.
All I can do is hold down the power button and trackball and get the page that says
bootloader
reboot
reboot bootloader
power down
the only way I'm going to get this fixed is to use my computer and I've never done it that way...I've always used ROM manager
I'll read the links but I think I'm screwed because a lot of this is over my head
Thanks for the links !

1) Try to follow "Unroot/restore" guide first, see if you can restore functionality using PASSIMG method. Once you have functional FRG33 with recovery, you can root it, replace the recovery and install custom ROM of your choice / update to FRG83G.
2) If nothing helps - consider a) replacing your phone, b) unlocking the bootloader and flashing recovery through fastboot.
Getting in over your head is sometimes a good way to expand your horizons

Hi Jack
Thanks for the help
I'll do some reading and see what I can do....got two feet of snow here so I guess I have the time
worst comes to worst I'm still under warranty.

Well I tried the instructions but nothing happens..it just sits on the screen with the androids skateboarding. I renamed the zip and moved it to my SD card but it doesn't seem to even search for it, let alone find it. Really wish I had not deleted storage. At least I had a working ROM at that point.

Which instructions did you try? Did you download FRG33, rename it to PASSIMG.ZIP (and not PASSIMG.ZIP.ZIP !), put it on the root of SD card and reboot to bootloader?

Hey Jack...
Sorry for taking so long to respond...I finally had to crash for awhile, my brain was frying.
Yes I did what you describe: downloaded FRG33, renamed it PASSIMG.ZIP(not ZIP.ZIP) moved it to SD card just like any ROM and held down volume and power button and came to the screen with the three androids. Then it just stayed there, nothing happened.
The only thing is I had to use my backup Nexus One(EDGE only on ATT model) to move it to the SD card as I don't know how to access the SD card with the device acting like this. If I connect the device to my computer while the three androids are on the screen, I hear it connect to the computer, but nothing pops up allowing me to access the SD card....
Like I said I'm a noob at this I appreciate you trying to help me here

About 3 seconds after the 3 androids skating appears, you should see some text flash up?
It does say you're in HBOOT and not FASTBOOT right? If in fastboot, pick the bootloader option and then it should find the file.

Hi Rusty
Sorry I somehow missed your post here. Yes I see some text flash up...takes a little longer than 3 seconds...maybe 8 seconds...
At first it says I'm in Fastboot, but then I press the power button and then it says HBOOT at the top.....that's when the text flashes on the screen. It flashes too fast for me to read it though....but nothing happens after the text flashes on the screen.

I'll be damned guys....I got it working! After responding to Rusty's post above, I decided to give the whole thing another try. Well I went thru the whole process of putting the file on the SD card and realized I had in fact renamed it zip.zip....it LOOKED like it was only ZIP, but when I clicked on the file while it was still on my PC, it said it was zip.zip...that's when I knew what the problem was.
My problem now is getting it re-rooted. Originally I used the Universal Androot application..the true one-click method...I just tried it again and it didn't work.
Is there a way to downgrade to a version where this app will work again?
Thanks guys you really helped me out here!!

Please read the guide in Wiki, and follow one of the zillion SuperOneClick threads that are around. It's really as simple as it gets - and if you happen to have Windows 7, it's even more simple - you won't need to install the drivers.

Yup I'm already rooted!!! Thanks man!!!! Took 12 minutes!!

Okay I'm having another issue: SuperOneClick said I was rooted,I have the superuser icon in my app drawer, but ROM manager will not flash Clockwork mod recovery and Titanium Backup says I do not have root rights??

well I rebooted and now have root rights but am still getting an error when I try and flash clockwork mod: it says: "an error occurred while flashing your recovery"

Do you have Busybox installed?

You're going to think I'm a dip**** but I don't even know what busybox is?

Let's just say it's an app that the system needs Go to Market, download and install it, try again. If it doesn't work - you can try to install custom recovery manually, using another guide from Wiki. Look in "Installing Recovery" for "For locked bootloader - flash_image using Terminal" guide. If you don't know what Terminal is - download "Android Terminal" by Jack Palevich from the Market.

Use the fix problems button in Titanium Backup to install it, long story short is it lets you use a bunch of native Linux commands that as missing from Android.

[Q] Urgent: Nexus failing to boot

Hi all,
I have had my N1 for 1year and two weeks now (yes, warranty just expired). I was charging the device and it seemed to overheat and reboot. I unplugged it, took the battery out, let it rest for a bit and tried to boot it again. The phone now gets stuck on the X logo (not moving) and never boots.
I'm currently abroad (in the UK) and can't have it sent back for repair (I'd have to pay the repair too).
Will rooting the phone and installing an alternate OS fix my phone?
Is there any way to get HTC to honor the warranty after two weeks of expiration (I've been getting this problem for a while now, but that was only an issue if I made extensive use of the device while charging, which I almost never do so I didn't bother.)
Is there any way to fix this issue without messing with rooting? I'm abroad right now and all I want is my phone to work.
Any suggestions are welcome.

Try booting into bootloader from power off (vol- pwr) if that doesn't work then try the 3 figure salute (pwr vol- tb) your phone should boot into fastboot then just select bootloader.
If either of these work the your good you can get the static x fixed all you need to do is passimg (search wiki if you don't know what it is) as for the charging problem passimg will factory reset the phone so if that doesn't fix it then no you'll need to try rooting or it might be hardware.

Yes, I'm able to go into the bootloader.
I tried clearing the storage, choosing fastboot, etc. The phone seems to be working, just won't boot past the static X.
From your last reply, you're saying passimg has good chances to fix my phone. What does that involve? Do you have a link to a how-to that I could follow (it would really be a bad time for me to brick my phone, a good how-to would be really appreciated).
Cheers!

Yes passimg is used for many things it just reflashes a shipment ROM to the phone through bootloader. Like I said you can visit the wiki to have a how to here is a link http://forum.xda-developers.com/wiki/index.php?title=Nexus_One/Guides_%26_Tutorials scroll down to "Unroot / Restore your Nexus" then follow the instructions. This should restore you to frg33 then you just need to update back to 2.3.4.
NOTE: this will wipe your data.

Ahh there's a way to unroot the nexus one now!
I had no idea! This is good to know (last time I checked was in December I think).
I will give that passimg a try as soon as I get home.
Can anyone confirm that this ("Attention: Latest stock ROMs don't flash using PASSIMG.ZIP method. Use the provided latest Froyo PASSIMG, and upgrade it after flashing.") means I can still reflash using this if I have the latest ROM (2.3.4) but will simply have to update again after (which I might not do given the issues I'm facing).
Cheers!

Confirmed - Dude is giving you good info... xD

Just to verify, unrooting is not the same as relocking. If you unlocked your bootloader (have a little lock symbol under the X screen), there is no way to relock it.
But the passimg is a good option. It will take you back to an older version of Android, and then you just let the system update itself.
Since you are out of your warranty, I can highly suggest looking into custom firmwares. These give you a lot more features and in many cases, perform better. CyanogenMod is probably the most popular one. These will fully replace your Android OS. CyanogenMod really doesn't even differ in look from stock all that much. Most people probably wouldn't even have a clue they are running something different, except for the stability and performance increases.
You can read up about this stuff in the wiki as well.

Oh, I see, thanks for the info.
I'm actually trying to get the FRG83 passimg file but the link is dead. Does anyone have an alternate one?

Use the FRG33 image

Alright,
I unlocked the device, used fastboot to write the recovery "Amon_Ra's Recovery".
Then I rebooted, went to the bootloader (trackball + power), went to "recovery" but the phone still gets stucked on the X (with the unlocked padlock logo).
Any advices?

Try the passimg, but it's possible that you are looking at hardware failure...

If you are still running stock Android, you can't reboot between installing the recovery and getting into it. Stock Android will replace it. Try to go back to the bootloader and select recovery then, or fastboot to load the recovery, and then use fastboot to boot off of it.
Code:
fastboot flash recovery "c:\location to\recovery.img"
fastboot boot recovery "c:\location to\recovery.img"
Hopefully this will get you into Amon_RA so you can try again.
But the passimg method is used in the bootloader, not in recovery. You don't need a custom recovery to use the passimg method.

Amazing, thanks for pointing out my mistake, that give me a little bit of hope now . (I was at the point where I'd open the thing and look for a broken solder joint.)
I will try this as soon as I get home!
**Edit** I actually am not sure if I really rebooted or went straight to recovery. I'll update this thread tonight.

According to some other people, this would be a common issue with the internal memory dieing.
Is there a utility I can use to check the state of the memory?

None that I know of. Our phone internal memory uses the yaffs2 (Yet Another Flash File System v2) file system. I haven't heard of any programs that can check it.

Same situation
Hello, all. I haven't signed in on here in ages just because I've been so happy with how my Nexus has been running.
I ran into the same problem as OP stated.
I think I have some sort of hardware issue because my phone used to randomly freeze and couldn't be restarted unless I pulled the battery. Now it's at the point where I can't even turn it on because nothing happens when I press the power button or if I try to boot into recovery. This is really frustrating.
Is there any way to check for hardware damage? My warranty is over as well so I'd have to pay for any repairs to my phone if I sent it in.

If it's running, you can try to pull a log, and see what error reports you get?

Your power button might just be dead. Try having the phone plugged into a power source and removing and reinserting the battery. While you are doing that, hold the Volume Down button. This will get you into the bootloader which would allow a passimg to be performed. Hopefully your reboots aren't a hardware problem.

So , after pulling my battery, pulling the sim and the sd card, it finally turned on and went to recovery without freezing. I was able to wipe and reflash cyan 7. It's working well for now, but I'm really afraid this is going to happen again because this isn't the first time that it's just froze repeatedly.
Does anyone know what the problem could be?

Alright,
I did "fastboot flash recovery MYIMG" then "fastboot boot MYIMG", didn't work.
Then I tried "fastboot flash recovery MYIMG" then go to bootloader (without rebooting) and selected recovery.
Still no luck.
It always freezes on the static X logo. What else can I do? Will using passimg be any different (I don't have any way to put the file on the micro SD card but I can manage to do it if it's worth the shot).
Thanks

[Q] Nexus One Stuck on Boot X

Hi,
Just yesterday my phone died and appears to be in boot loop. The X is stuck on the screen. I've been reading through some forums and heard trying to reboot with the SD card, but that didn't do anything. Unfortunately my main problem is that my power button is also broken, so I can't do a system restore or fastboot. My phone isn't rooted and I'm new to the technical stuff of phones so if someone could give me some help or advice I would greatly appreciate it.

in a smiliar boat
I dont mean to step on the OP but maybe my situation could help shed some light. My N1 is displaying the same symptoms but my power button works fine. If I power up while holding the trackball, the only thing that shows up as selectable items are:
BOOTLOADER
REBOOT
REBOOT BOOTLOADER
POWER DOWN
Way back when I rooted my G1, it seems to me there was a much more extensive menu available at this stage. I'm willing to root and flash at this point if needed--I just need this to work as a phone for my non-data using wife. Any suggestions appreciated.

I suggest you should do some reading first to get familiar with the procedures and then work on your N1. Here is the Nexus One Wiki on this thread which has extensive information http://forum.xda-developers.com/wiki/index.php?title=Nexus_One

I've been reading the wiki for two days but I keep running into roadblocks. I just now realized the fastboot was highlighted by default (duh). It's coming back to me now. I'll just keep plugging. Thanks!

I had your exact problem at one point. Broken power button, locked bootloader, stuck at the boot up screen, only difference was that my phone was rooted. What I did to fix it was the PASSIMG.ZIP method which can be found on the wiki here.
You're going to need an alternative method to putting the ZIP file on your SDcard since you can't boot into Android to mount it. If you have one, use an SDcard adaptor to plug the card directly into your computer, or use another phone and mount it from there.
Good luck!
(Not sure if this is what you did and meant when you said "reboot with the SD card," hopefully it's not)

I've tried the ZIPIMG method but when the phone reads the file it just says 'No Image or Old Image' and goes back to Fastboot menu

I'll give remote access to my computer / device, and even talk on the phone. I have all files I can find downloaded, but none will root the device or roll back, etc. I can't access the bootloader in any way (power / volume down or power / volume up just result in a normal boot).

this should help you
http://forum.xda-developers.com/tmo...ck-guide-h811-20-o-bootloader-unlock-t3421589

Yes, this should help resolve your issues. What you wanna do is get ADB on your computer. Download the file in this link. It will get everything running, system wide. I did this, personally, because I'm a lazy mofo. Also, you want a custom recovery, not your bootloader
http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
Next up, you wanna enable developer setting on the phone.
-Settings....about phone....software info.....click on "build number" until you are granted developer settings (it'll say it.)
Click back, twice and you'll see Developer Settings. Go there and make sure developer options is toggled ON, up top.
Make sure "Enable OEM unlock" is checked. Scroll down and make sure "USB debugging" is checked on.
Grab all your files (cyanogenmod and gapps) Put that in a folder. and recovery img, you'll need that.
Plug your phone into your computer....Make sure you allow USB connection! Your phone will prompt you about this.
Now, within the folder,with all your files, including your recovery img, hold shift and right click. Click on "open terminal here"
Type in "adb reboot bootloader"
Your phone will boot to a black screen with some writing on the top. Since you said it's bootloader unlocked, let's move on.
type in "fastboot boot twrp-3.0.2-0-h811.img" (FYI, please have this downloaded, and in the same folder as you opened the terminal window)
Your phone should now be in TWRP recovery! Your phone should still be recognized by your computer, so open up the device, so you can browse the files of the phone.
Windows start menu....file explorer....this PC....click on your phone.
For the sake of simplicity, transfer all your files, including the recovery img, to the phone.
Once all files are on, click on "install" click "install IMAGE"...look for your twrp file and select it. THIS IS SO IMPORTANT! FLASH IT AS RECOVERY!!
Swipe to confirm...done.
Hit the home button....click "reboot"....click "recovery".
This is just gonna boot you back into recovery, so you know that you have a permanent recovery!
Next step is to backup...click it. Just swipe to backup. The three important things are checked (system, data and boot.
Once that is done, "wipe" (click it) swipe now. The recovery will do everything for you. Factory reset, basically. It doesn't wipe your internal storage, so your CM and Gapps are still gonna be there. ALWAYS BACKUP. Everybody knows that a backup can really save your ass!
Once done, "install"....click on CM then click "add another zip". Click on gapps. Now, swipe to flash the files
The recovery will do it's thing, and will confirm when it's done and successful! "Reboot system now".
The phone will take a bit to boot up, get apps ready, etc etc.
Welcome to Cyanogen mod.
If for any reason you get red errors and are panicking , just "wipe" again, then click on "restore" and swipe. Once that is done, you can reboot into stock and still have a functional phone.

Maybe try installing these drivers before using the "adb reboot bootloader" command inside of LG Root folder.
-install "LGUnitedMobile_Win_Driver_Ver_3.14.1"
Download:
https://www.androidfilehost.com/?fid=24052804347823763
-install: "adb-setup-1.4.3.exe" to get adb and fastboot drivers etc.
Download:

-you may want to restart your computer.

I did what was suggested in post #2. It got to 98% and never finished. The phone shut off and has never restarted again. Completely dead. I sent it back to LG since it had a s/n starting with 505 and see if they'll replace it.
Dead phone, dead issue.

These guys did the deed for me. https://www.oneclickroot.com I screwed around for DAYS before I just had them do it in a few minutes.

I had a similar problem, took out my micro SD card and redo everything over and it finally rooted.

This one is history. It won't power on under any circumstances (with or without battery). Like I said it was a 505 s/n and LG did give me a return number and even paid the shipping. They know of the 505 problem and what I was doing probably put it over the edge.
I was going to put CM on it to see if I could get wifi tethering to work on T-Mobile. FoxFi nor any of the other tricks seemed to work and I was hoping CM would allow wifi tethering. Anyone know the answer?

As for me, I accidentally flashed a lower fw version and screwed it up, filed a repair ticket through LG, told them it died and wouldn't come back on after the T-mobile ota, they replaced the board, no cost, due for delivery tomorrow, didn't need a receipt or proof of purchase either.

I used every fix in a combo.. fixed without lg help.. someone need to clean up my post and repost as a thread for a cheap permanent fix.. the problem starts from the rubber resistor in the battery.. the phone doesn't get the right amount of power from the stock battery so the phone gets hot from over compensation. Then the CPU/GPU will get so hot that the contacts to the main board get a little faulty.. when I bought the phone it bootloop bad and never got pass the LG boot screen.. tried the freezer trick which made the phone moist for a better connection but only boot to home screen then bootloop again cause it also has bad thermal contact.. then I did the heat gun I fix with a blow-dryer. It ran perfect until I ran an app. I then followed a guild and added a thermal pad directly on CPU and GPU. Then added thermal paste between the metal frame and the metal that cover CPU/GPU. Ran for 15 to 30 mins before bootloop.. all the time I need. I then followed a guide for bootloader unlock. fastboot boot TWRP. Flash TWRP via TWRP. Then reboot into TWRP ( if you try to fastboot flash it will fail and you will have no recovery) to make sure it stuck. Flash supersu and thermal mod from xda. Rebooted and downloaded BusyBox.. now stable but running hot. Flashed a nougat ROM.. running perfect but got 43° average instead of 63°. Used kernel editor to disable 2 big cores and thermal throttle and set everything to enable on boot. Perfect and stable no matter what in doing. Temp stay between 23° & 33°. I plan on using better thermal paste, pads and getting the TOTHL battery for better stability without a mouth full of mods.. who needs lg help? Not me.. good luck guys. There's a debate about what the real issue is. Simple.. every answer is correct which made it fixable for me with sending anything to lg. The processor is very powerful and the battery resistor is the source. I also tried a more powerful battery before any mods. When the processor needed more power I got a pop-up message about use an LG ( original) battery before it bootloop. Also with the more powerful battery, I'd get a message if I tried changing it with the phone off saying not compatible but since using a custom ROM it work fine. Lg has something in the stock software to make people think paying them extra for warranty or tech fix is the only solution. That is your only option if you bone stock. That's why they still sending patches.. to the g4.. to block root meaning you will have to pay them for fix..

Solved - Plz try my way, if does't work, I will change the Title
Gentleman, Please try the following and don't forget the bounty $s lol.
I hope you have all the files and pc is reading your phone in adb.
Keep the downloaded twrp file in your adb folder with dwonloaded name (Ex:1234twrp.img)
Copy the same twrp file and keep in phone internal storage with named recovery.img
adb reboot bootloader (wait for phone to boot in bootloader ofcourse)
fastboot boot 1234twrp.img (whatever your twrp img file name would be in your adb folder)
Now you are in twrp recovery page in your phone.
Tap Install (STOP) > Images (bottom right) > select recovery >
Now you are in next screen where options to select recovery or boot
Tap recovery and swipe you will see [image flash complete]
Now twrp is permeant. You can restart in recovery without PC. (Tested)

in twrp install and select your downloaded rom zip file. I prefer the second link. You have options to remove all LG junks.
Don’t run this rom with temporary trwp (which can start with pc only) then your will lose twrp and your OS and you have to do download mode and kdz thing.
Good Luck and please let me know.

It's bootloader unlocked, but can't get into bootloader. I wand Cyanogenmod on it.
I'll give remote access to my computer / device, and even talk on the phone. I have all files I can find downloaded, but none will root the device or roll back, etc. I can't access the bootloader in any way (power / volume down or power / volume up just result in a normal boot).
I will pay via PayPal. I need this ASAP. I don't know what I did wrong, but hope you're the person than can fix it and install CM (or any other way to wifi tether on T-Mobile / Simple Mobile).
Serious offer. Can you do it? If so make some quick cash.
Thanks,
