Please help me install the recovery image on my rooted Nexus one!

Hi all,
I am completely at my wits end here and just don't know what to do
I have successfully unlocked my stock Nexus One boatloader, and have installed superboot to root it.
- I am using Windows 7 64 bit with all USB drivers for the nexus one correctly installed
- I have remembered to reset debuggingt mode in the Nexus USB settings
- Rooted apps seem to be working fine - I've just been playing with the LED torch app and I have a 'Superuser Permission' icon in my programs list
I am attempting to install the Amon_Ra recovery file - I've tried two different versions of it with no joy so far.... 1.7.0 and 1.6.2
I am able to boot into fastboot (with the skateboarding droids) with no probs. I can see the device using fastboot devices. However, when I try to send any recovery image using fastboot, it just hangs there with an empty progress bar on the right hand side of the screen in green that doesn't fill up.... Here is the terminal output:
---
C:\AndroidSDK\android-sdk-windows\tools>fastboot devices
HT9C(-REMOVED-) fastboot
C:\AndroidSDK\android-sdk-windows\tools>fastboot flash recovery recovery.img
sending 'recovery' (3948 KB)...
---
Anybody have any idea why it hangs here and if there is anything else I can do to maybe figure out why? I'm pretty certain I've almost cracked it - installing this recovery image is a problem
Thanks in advance!

don't rename the recovery.img file.
Then if that still doesn't work...maybe try using a terminal on your phone. Not sure myself which terminal app works.

Thanks for the quick response!
It still fails even when I don't rename the recovery image.
Re 'using a terminal on my phone' - is there a guide to this anywhere? Do I download a shell or something?
TIA!

Go to market and search Android Terminal Emulator.
Then follow these instructions:
via terminal app
Code:
Copy recovery-RA-nexus-v1.7.0.img to the root of your sdcard
start the terminal app
su(press enter)
flash_image recovery /sdcard/recovery-RA-nexus-v1.7.0.img(press enter)
reboot recovery(press enter)
Got those instructions from the Recovery thread.

It looks like fastboot is not properly detecting your device? Also, did you install "superroot" before attempting to flash recovery image?

Thanks everyone for the help so far.

I have tried these steps - when I issue the su command, I get root and a dialog box prompting me to allow it. However, when I type the flash_image command, I get the following message:
flash_image: not found
How is it that I don't have the flash_image command on my Nexus?!

I think fastboot is detecting my device, because I managed to display the serial number (I obsficated most of the output above for security reasons) and I also successfully unlocked the bootloader. After I unlocked the bootloader, I tried to copy over the recovery image, and it just hung, so I then went and installed Modaco's superboot version ERD27 with himem enabled. This allowed me root access but still will not allow me to flash with the recovery image.
In addition, I have noticed that since I installed superboot himem, I am having a couple of network issues. Firstly - my 3G signal has now dropped from virtually full strength all the time to now never more than 50% strength, and frequently gives network errors when accessing the android store. It has also said "emergency calls only" a couple of times and probably worst of all (!) no longer checks my gmail automatically (I have plenty of emails but don't get notified - texts work fine though and my contacts are all still there and my account seems to be linked) - could the superboot have affected this in any way?
Thanks all for your help - I'm getting a little worried I may have totally borked my phone now

A little extra info if it helps anyone - I just tried to erase the recovery image in fastboot to see if I could then write a new recovery image. Here is the output:
---
C:\AndroidSDK\android-sdk-windows\tools>fastboot devices
HT9CXP8##### fastboot
C:\AndroidSDK\android-sdk-windows\tools>fastboot erase recovery
erasing 'recovery'... FAILED (remote: not allowed)

Anybody have any clue what this means?

Try to redownload the recovery image, maybe you got a bad download.

Can you try a different USB port? I found when flashing mine that it didn't like USB1.1 only worked on USB2.0

Another thing I discovered recently: Never use a port on a USB hub. Always use a USB port on the PC directly. I was having trouble flashing ROMs on my Acer Liquid and they went away when I stopped using a port on the hub.

without a doubt i bet its a naming issue, this is one of those things that go unmentioned and overlooked. either u do or dont have file extensions showing or not and or the .img does or does not need to be changed to .zip, i messed with this for days last year when flashing my g1. just go and change whatever you hide/show known file extensions is set to and see if ur problem is solved.

Thank you AndyBurns. I registered just to say that. You saved me a lot of time.
I had the same problem. Had the USB cable plugged into my front 1.1 ports instead of the back 2.0 ports. Switch ports and now I'm good to go.
Thank you.

Hi all -
Just wanted to post a follow up to this message, in the hope that it may help someone in the future!
Basically, I was not using the original USB cable that came with the nexus one (lost it), and instead was using a cable that I bought from a mobile phone retailer - it was basically one of those 6-in-1 multi USB cables where I had to put an adaptor on the end to switch it from mini to micro USB to fit the Nexus one.
Anyhow, for some reason, despite the fact that I could charge the phone using this new cable, and access it through device manager, explore the contents of the phone, root it etc etc, it would not do the flash as described above. I went out and bought a dedicated 1 metre gold plated micro USB cable, and it worked great
Dodgy cables - should have thought of this before I spent days frigging around and maybe even almost bricking the phone with a bad flash

[Q] Corrupt bootloader and black screen but live usb -- still hope?

Hi there
@bftb0 : yet another victim of the corrupt bootloader .img ! (see thread #2573015)

Device : Nexus 7 2012 wifi (grouper), stock 4.4.4 KTU84P, never rooted before
Symptoms : black screen, not booting at all even to bootloader. :crying:
Only faint light of hope is that my PC is still reacting to plugging the Nexus in with USB.
Windows beeps and shows an "unknown usb device" error then fails finding a driver.
Windows Device manager shows "APX" with yellow sign below "Other devices".
Question : bricked or any hope left ? Pleeease what can I do ?
How I got there :
NRT hung when flashing bootloader while reinstalling stock 4.4.0 (nakasi-krt16s-factory-da7dee49).
The story, going from bad to worse :
It started with a sudden reboot for not appearent reason (incidentally while an Avast routine scan was running).
Then endless reboot, with the 4 color balls shaking indefinitely (power plugged in or not).
Looked at forums... Reboot into bootloader. Recovery mode, wiped cache. Got plenty of error msg "E:failed to mount /cache"
Bootloop! Sometimes showing just the white Google logo, sometimes showing the rolling colors for a few seconds.
Recovery mode, erase user data (no backup, hate this thing). Again plenty of error msg "E:failed to mount /cache"
Could the missing /cache be related to Avast since the first reboot occurred while it was running? Maybe the theft protection is overly proctective?
Installed Nexus Root Toolkit 1.8.4 (extremely well done utility btw, ***huge congrats*** :good on Win 7 64bits. Installed drivers #1.
Tried flashing a clean 4.4.4 (nakasi-ktu84p-factory-76acdbe9).
FAILED (remote: Bootloader is locked.)
Successfully unlocked bootloader with NRT. Restart with an open lock below the white Google logo. So far so good.
Try flashing 4.4.4 again, same image.
writing 'bootloader'... FAILED (remote: (InvalidState))
What the heck ?!
Found the thread #2573015 I was quoting above on corrupt bootloader .img files from Google.
As it turns out, the bootloader MD5 is also WRONG in KTU84P.
Managed somehow to restart into bootloader again in spite of the bad bootloader...
Maybe the old one was not completely replaced yet?
Quick quick, let's try flashing another bootloader that works !
This time use the latest available with a non-corrupt bootloader .img : 4.4.0 (nakasi-krt16s-factory-da7dee49)
erasing 'boot'... blahblah
sending 'bootloader' (2100 KB)... OKAY [ 0.281s]
writing 'bootloader'... *** STUCK ***
Wait and wait until lost hope
Tried rebooting but nothing happens, just black screen, I end up with the symptoms I described upfront.
When plugged into the pc, keeping power button down makes windows beep, and the "APX" unknown device comes and goes in win device manager. Adding the vol+ or vol- buttons (or both) produces identical results.
Uninstalled APX device from PC. Power button down. Windows beeps "unknown usb device". "APX" shows up again in device manager... And so on.
Screen still pitch black.
Any other USB driver I can try to regain a working connection?
Worth looking into other remedies, like nkFlash?

If you corrupt, or erase the bootloader... the Nexus 7 is dead, from which there is known recovery. Although it's been speculated that an nvFlash tool could flash a new bootloader.

What a similar story
this is such a coincidence as I have also had the dreaded bad to worse stage as my story started off here http://forum.xda-developers.com/showthread.php?t=2783631 and then got much worse and it continues here http://forum.xda-developers.com/showthread.php?t=2798181 .
I have been searching on the internet for the last month and so far there does not seem to be any general solution (which does not require hardware device surgery) to this particular type of problem as it is not something Google appear to have expected. I found that a lot of people seem to say its hypothetically possible to repair this thing via software means as that is how it was rendered inoperable in the first place and they also say it is not practically possible to hard brick any device through software means although with the nexus 7 there seems to be some kind of issue with crypto-signing which makes it a nightmare to access the hardware through nvflash unless there was some blob file made before hand

[Q] Permanent problem with Unlocking Bootloader Nexus S

Hi guys,
I searched forums, web with no positive results. So I start a new thread. Here is the situation: one day my Nexus S (Worldwide edition) froze on restarting with the Google Logo on the screen. Every time I try to turn the phone on it stacks at Google logo. When in the fastboot mode the status is Locked. Every time I try fastboot oem unlock I get Phone’s prompt with Yes or Not to unlock bootloader and after choosing Yes, the status doesn’t change to Unlock. Tried on Linux, Mac, Windows (drivers installed successfully), the same result. Tried to force Flash Stock + Unroot in Wugfresh, doesn’t work due to the Locked Bootloader.
typing "adb devices" in cmd (should return the device number) shows:
List of devices attached
......
Empty line above
Any word of advise how to force Unlocking the Bootloader would be greatly appreciated. Please help. Thank you!

It looks like your device is not recognized in Fastboot mode...
Have you turned on USB Debugging while connecting PC and Allow in Device when Prompt some message ..
Go to fastboot mode and write this command... fastboot devices
If it will give you a message like this
List of devices
1235456785164
Then your devices is successfully recognized...:good:

It is not recognized by adb devices, but:
fastboot devices - gives the following output:

Pretty sure you have a bad USB cable, the error means the fastboot binaries are working on PC but can not connect to device, often this is due to a bad USB cable or port
Try a new cable, one you can verify works transferring data

Thanks, I tried 3 different cables on 3 different operating systems, with the same problem unlocking the fastboot. When I send fastboot oem unlock the device opens a prompt with Yes or No choice, but after choosing Yes, it stays Locked

Something indeed is strange...
So fastboot is for bootloader and adb is for within os and in recovery.
Try booting into recovery and see if adb works, also boot normal into your bootloop and see if adb works there too

Loading into basic recovery and trying to wipe data/factory reset - doesn't work. adb devices returns the following output:
./adb-linux devices
* daemon not running. starting it now *
* daemon started successfully *
List of devices attached
****empty line here****
Somehow, adb doesn't recognize the device, whereas fastboot devices shows it.
Is there a way to flash new bootmode with the currently locked bootloader?
Thank you!

Hope this Guide will help..

UPDATE (resolved)
Here is an update. Hope this would help others with similar issue, as I've read many threads and folks complaining that they weren't able to unlock fastboot and further root their Nexus S, and who can't boot the phone, which stacked with Google Logo (soft loop). This was the case with my device and finally I got it resolved. I've read some guy tried to hit the phone and after that he was able to boot phone normally. It related to some hardware electrical circle issue. Anyways, I tried to hit my phone by placing it under the direct sun in balcony for some time until the phone got hot and then power it on. And ooops, my phone started booting passed by that Google Logo which was the good sign. Once the phone booted up, I went ahead and activated USB debugging and restarted the phone into the Fastboot mode. while the phone was still hot and in Fastboot mode I run "fastboot oem unlock" and hey, fastboot is Unlocked! Again, this was done while the phone was hot, any previous attempts (read above) weren't successful. From that point, I went ahead and rooted my Nexus S by Nexus Root Toolkit, available on wugfresh.com/nrt, without a slightest problem. Now my phone is fully rooted, bootable and working fine. I thank all who replied to my thread and tried to help and hope this info would help someone with the similar issue.

Alcatel OneTouch POP C7 (7041d) Bootloader unlock

Hey guys,
Ive been trying to unlock the bootloader on my phone to install TWRP. I have ADB and fastboot installed properly, I have usb debugging enabled on my system and I am my computer's administrator. When I turn off the phone and then open the terminal in platform-tools, I can type in the command to reboot into the bootloader, and my phone will turn off but the screen will stay blank. If I then type in fastboot devices, I can see my phone and that its connected and ready.
However, when I type in fastboot oem unlock I get back 3 dots in the command line, and nothing hapenns. I can wait there as long as I like, nothing will happen. If I unplug my phone, it says
FAILED (status read failed (Too many links))
finished. total time: 4.945s
I'm running an unrooted 7041d on Android 4.2.2. I also have my phones USB drivers installed (or I think I got the right ones)
Does anybody know what to do / how to help?

Greetings,
Thank you for using XDA Assist.
To best assist you, I'm going to move this thread to your device's Q&A section.
You should receive expert advice there.
Good luck!

Same problem there.
I have pop 4 plus and I think most of the Alcatel devices are blocked. If I find anything, I will try to help.

Need help. Tried rolling back to Kit Kat

Ok, had a slight issue getting everything to work with windows 10. Anyway i was able to get everything going eventually however when I ran "flash-all" i wound up errors all the way and ended with
