Help! Cant boot g1 after "danger spl"

I updated my phone's SPL to "Danger SPL" and now my phone wont turn back on! I press power and the black Android screen with the little green android next to it comes up but wont boot my phone! The only thing I can do is get the white screen with the 3 android's skateboarding by pressing camera + power.
Ontop of that, I had tried to update my phone's recovery image too, and I erased the old one and now it would let me upload the NEW one! So not only do I have NO PHONE but NO RECOVERY either!
What do I do!? HELP!

can you get into fastboot? (back+power)
if you can, get adb running and flash your recovery image with fastboot

you are gonna have to fast boot in the screen with the three androids on it, either a rom or a recovery
guess you betta learn how to use adb

Yea I can get into fastboot, thats the ONLY thing I can get into. How do I flash my recovery image?

http://forum.xda-developers.com/showthread.php?t=566669

boot your phone into fastboot. plug in your usb cable to your pc. this should change the fastboot icon on the screen to fastboot usb. from there, load up adb on your pc and make sure you have the fastboot option available by typing fastboot devices. it should list your phone. once that is good, type:
fastboot flash recovery and the correct name of your recovery file.
for example:
fastboot flash recovery recovery-RA-dream-v1.2.3.img
**also note...put the recovery image in your android sdk\tools folder**
this should give you a recovery to boot into.
if you dont have adb on your pc, read this and follow the instructions
http://forum.xda-developers.com/showthread.php?t=532719

I did that already, it wont work.
C:\Android>fastboot flash recovery recovery123.img
error: cannot load 'recovery123.img'

i am gonna be the one to ask this question but did you put .s between 123 like 1.2.3.

you need to be in the tools directory, not the android directory.
c:\Android\tools>fastboot flash recovery recovery-RA-dream-v1.2.3.img

and you need the recovery file IN your tools folder for it to be found as well.

No I didn't put .'s between each number I renamed my file recovery123.img so thats the way I put it in.

ok, so go to the correct directory and input what you had the first time, WITH the file IN that same folder. and then report back.

i justed rename my recovery the shortest way i can like for amon ra"s i just put amon, less typing is always better

It says C:\Android\tools is not recognized as an internal or external command, operable program or batch file.

from your c:\> prompt type this:
cd c:\android\tools
(this is assuming you have the android sdk in the c:\android folder on your pc)
if it is saying its not a folder, then that is not where you installed the android sdk.

This is not true. You can have it anywhere as long as you can cd to it and you have your fastboot.exe in the system32 folder.
Look... this is so easy I'm wondering why this has gone on for more than 1 page.
First thing is first. I'm betting that you don't have the new ADB driver for the Danger SPL.
If you refer to this page:
http://sapphire-port-dream.googlecode.com/
it states:
If you use the above SPL you will need new drivers for Windows. They are located here.

Click to collapse
Then put your fastboot.exe in c:\windows\system32 directory.
Whatever recovery file you're trying to use rename it to "recovery.img" and put it on C:\ then open command prompt (start > run > cmd > enter)
cd c:\
fastboot flash recovery recovery.img
and it should show a progress bar in the top right corner.
While the dos screen shows 'sending' and then 'writing'.
After you see ...done a second time then type:
fastboot reboot
and it should reboot just fine... but you may need to do that "3 finger solute" (talk, end, menu) while holding the camera button down to get into your recovery. You should be able to flash your rom. Just make sure the rom doesn't have a radio update (unless it's the 2.22.19.26I).

No problem. I just hate it when something this simple drags onto multple pages. Call it a peev. So many people get intimidated by the "Danger SPL" because they don't want to risk bricking their phones. The odds of bricking your phone are extremely small if you follow directions and read everything. And sure the possibility of accomplishing this by different means exists. But when you try to tell someone to put this file in that folder and type in the full names of the files to include all the dots and dashes, it's going to get confusing and intimidating and thus these posts keep popping up.
If someone follows those very short and simple directions they shouldn't have any problems. Granted that "**** happens" and things don't always go as they should. So in that case, search for your answer. If you've searched on XDA then search Google. Out of the MILLIONS of G1's that have been sold, I am fairly certain that someone out there has had a similar problem. If not then you and your phone are literally "1 in a million" (technically it was 1 in 1.5 million a year ago so you can bet that it's well over 2 if not 3 million by now). And if you really fall into that catagory then please post a new thread (in the appropriate catagory of course) .

well the good news is u didnt brick ur phone but try a enter adb and do a nadroid back up if u hav 1 that will bring u back 2 the way u want it

either flash a nadroid or flash dreaming.nbh....i had the same problem and a nadroid worked just fine

Help with Recovery.img

I wanted to try Cyanogens new Rom when I bumped into snag on the first step.
I cant get in Recovery mode! I have done it befor to get root access but I dont know what happened. It always freezes at the Rogers Logo when I hold Home and push power.
I have very little knowledge of this stuff but Ive tried to install Cyans Pimped recovery.img but It keeps telling me cannot load recovery.img. I think I only tried through fastboot though, I have attempted to through adb shell but I'm not 100% how that works, so I assumed it failed.** Oh and I also Tried erasing my old Recovery Image, which was successful but didnt help anything
I have root access and I own a Canadian HTC Dream. I have Cupcake, Thanks for your help in advance ^^

Hi, it sounds like you erased the standard recovery image, but haven't sucsessfully flashed a new one, which is why the phone will have.
Try flashing it on your phone using the terminal. First grab "terminal emuator" or "Better Terminal".
Put the recovery image on the root of your SD card and name it recovery.img
Open terminal and type:
su <- when the prompt appears, choose always allow
flash_image recovery /sdcard/recovery.img
It's done when the cursor drops down to the next line. Turn the phone off and hopefully recovery will be working.

Hey thanks for the response but still having the same problem.
When I type su it always says Access Granted Courtesy of yada yada. Im assuming this isnt a problem. I flashed my recovery.img and it didnt give me a response. I guess it worked but yet, Still Freezes on Rogers Logo.
I found the Right Recovery.img for a Rogers Dream but now I cant seem to flash it into the Phone. When I type the cmd in Terminal It doesnt give me any errors. But when i go to Erase it in Fast boot it says the remote partition does not exist. Can anyone figure this one out? Im probably doing something small and stupid wrong but any help would be greatly appreciated.

Sounds like you have few different tutorials mixed up. You don't type cmd in terminal. cmd is Windows command to get into command prompt, from there you type your adb commands so if we assume that you placed your NEW recovery image in the root of you sd card and named it recovery.img you would type
From your computer
Window's key +r
cmd
adb shell
flash_image recovery /sdcard/recovery.img
reboot recovery
OR
From terminal
su
flash_image recovery /sdcard/recovery.img
and wait for # to appear, then type
reboot recovery and see what happens
There's a way to do it from fast boot screen as well, you can find a tut in developement section.
Good luck

Hey thanks, That does clear a few things up. I just ended up resetting my phone and it was a breeze from there. Thanks for your help.

How to flash stock recovery.

Hi guys,
I have to send me N1 to htc for fix some problem.
I have RA recovery with lock bootloader, and I want to flash the original, but "fastboot" way doesen't work (signature fail ).
How can i flash it in other way?
Ty
(sry for my eng )

Just flash the stock rom with the recovery image like frf92 original.

How? Through recovery? Because "fastboot" hates me, and won't work.

I'd suggest using a passimg for frf85b and then maybe updating to 91 (or just leave it at 85), you can always re-root when you get it back.

N1 w/ XDA App

got it, thk to cyanogen wiki
Plug the phone into the computer
Reboot into fastboot by holding TrackBall + Power (you should see three Androids on skateboards and the words 'fastboot USB' in red)
On the computer, open a command prompt cd to the sdk/tools directory (we will assume the SDK is located in C:\android-sdk and the recovery file is in the root of the sdk/tools directory for the following steps)
With the phone connect via USB, open up a cmd prompt
Code:
adb reboot recovery"
Code:
adb devices
​A device name and 'recovery' should be returned
Code:
adb push recovery.img /sdcard/recovery.img
​recovery.img is located on android-sdk/tools dir
Code:
adb shell flash_image recovery /sdcard/recovery.img
​This permanently flashes the recovery.img to your phone, you can now boot into it by holding Vol- while powering on the device
Reboot

[Q] Stuck at Fastboot usb screen

I installed the new zen2.2 rom today and had a working clockwork recovery. Here is where I went stupid, I downloaded the kernel update but rather than running it via update.zip I flashed it using flash_image recovery via adb shell.
Now my phone comes up to fastboot usb and never goes any further, been waiting hours! I have tried booting into fastboot/hboot and it does nothing. I have booted to hboot before successfully but now nothing.
If I run adb devices it shows no devices. If I run fastboot devices it does show my device.
Whats next?

If you cant get into fastboot and you cant get into recovery then you m ight have bricked your phone. Did you try a hard reset?

How do you do a hard reset?
Here is a little more info. I believe it does actually get to fastboot usb as it says so on the top left of the screen and I can run fastboot commands but most commands say error. If I do fastboot devices it shows the device connected.
Little more info - when I try doing a back to basics RUU update it connects, shows the rom version, starts the update and then at about 88% every time, it goes right to a error [171] usb connection error. So its communicating but never finishes. Tried with the sprint RUU stock rom, another that was built by one of the devs in the Hero community and still both do the same.

I'm pretty sure you can flash a custom recovery from fastboot. Using something like fastboot flash xxx dont quote me on this but it sounds like you have a soft brick and you just need to get a recovery back on the phone. From there you can then flash and rom back on the phone. Do some research on flash a recovery from fastboot.

Right, I also believe that if I could get a recovery back on the phone I would be good as gold! Here is the problem though. I have tried running "fastboot flash recovery [recovery.img]" but it gives me the below error. I have tried multiple key combination's to get into hboot but nothing works. If anyone has any other key combination's I could try please let me know!
Code:
D:\android-sdk-windows\tools>fastboot flash recovery recovery.img
sending 'recovery' (3720 KB)... FAILED (remote: not allow)
finished. total time: 0.001s

1st:The ONLY time you use flash_image recovery is when you are installing a recovery console, NOT a kernel
If you notice the kernel is in a signed .zip folder. When you use flash_image command it needs to be .img file
2nd: Put the recovery image on your sdcard
Put it in the tools folder of AndroidSDK and do
Code:
adb push recovery.img /sdcard
Now type in
Code:
$ adb shell
$ su
# flash_image recovery /sdcard/recovery.img

I am fully aware of how the how-to's and what not to do's. Like I said, it was a mistake, call it a bit of anxiety due to the new 2.2 rom that I was trying to get installed. I did it too quick and without much common sense .

For the second part, I am unable to do anything with adb as my computer does not see the phone. When running adb devices it is not listed. Only command that sees my phone is fastboot devices, but again I am unable to run anything aside from that due to previous error.

First do you have the eng spl, does your hoot say s (on)
Have you tried that command but point it to the sdcard? Also do you have any files on your sdcard like say a recovery.img or an update zip. If you don't you might need to manually move the file to it and try some of these commands
fastboot update /sdcard/<imagepackage>.zip [-w] -w will wipe the cache and the user/data
or your previous flash recovery but with the file pointing to the file on the sdcard
edit: sorry i dont think fastboot will see the sdcard but try anyways.

I will try the fastboot command right now. I am unable to get to hboot with any of the key combination I have tried, before I was able to. Only thing that always comes up is the HTC white screen with fastboot usb at the top left. Can't see what hboot version or anything else I have due to that limitation.

After reading a bit you should be able to do something like i described
- copy amon_ra image to yor sd
- flash_image recovery /sdcard/name-of-recovery.img
hopefully you have a way to copy the files to your sd card like say a microsd card converter and stick it in your comp. Or I have had to use a freaking camera once for my g1 after being in a similar situation.
edit: ok so maybe you wont be able to if you spl is in s-off mode.
if you can access your card and see if you have nadroids you could also try this
fastboot flash system /path/to/nandroid/system.img
fastboot flash boot /path/to/nandroid/boot.img
fastboot flash userdata /path/to/nandroid/userdata.img
fastboot reboot
hopefully you have these backed up on your puter to.

Negative on the fastboot commands. Also did have a nandroid but on old sdcard which died. I read that I could use anothers nandroid backup but I am currently trying to find one to test.
Tried doing the RUU method with stock/custom roms and it gets as far as seeing the image but when I click on "ok" to start the recovery, it goes to "waiting on bootloader" and then at 88% it errors to a 171 error stating usb connection error.

I would do some research its my understanding that you can't be bricked since you can get into spl. You should be able to put an .img file on your sd card and flash it. Sorry I can give you any more input.

Ya I have been researching non stop all yesterday evening and today so far all day. I just cant get it to do anything. I will keep researching though. Thanks

Did you fix this yet?

Anyone figure this out yet...I have the same issue and haven't been able to resolve it yet. Still with a brick at this point!

Hey guys,if your stuck at fastboot(As I just was tonight), try in your CMD(if running Windows) fastboot reboot-bootloader or fastboot reboot to reboot as normal,I'll try to keep you updated to get through all this. I am at a loss right now but searching for answers first before i go about asking.
Answer to MY problem(maybe not yours): OK,I have come to the conclusion here tonight that I had a soft brick. What I did was remove the battery,put the battery back in,restarted the phone normally,then I ran the HTC Sprint Hero MR 2.27.651.6 on my computer(essentially restoring back to unrooted factory settings). This worked for me. I am totally refreshed and happy that my phone is ok and all. Yes I may have to go back and re-root but this only take me bout 20 minutes most to root and re-flash a CyanMod7 Nightly Rom. Hope my info can help out somebody!

tried to install JB, used Blackrose = can't get into recovery

Hello Folks,
I'm still stuck with my nexus one since I don't care that much about phones.
I've seen that jelly bean roms have made a significant progress. Thus I decided to give it a shot.
I started with installing adb and fastboot. :good: After that I rooted the nexus one :good: I've used this how to:
c2med blog, can't post links...
Next, I ran blackrose. :good: I saved the rom on the micro sd. Having done all the preperations I wanted to flash the JB rom.
I started the phone in bootloader mode but - unfortunately - couldn't access the recovery mode (ext4). I only get the Android figure and an exclamation mark.
In the how-to it sais i should use fastboot to flash the recovery made by ext 4.
Problem # 1: Ext4 generated a .zip, not a .img file
Problem # 2: I connect the device in fastboot mode, navigate to the adb/fastboot folder and use ./fastboot devices. The phone is recognized and I see the serial number. Next I try "flash recovery...." but I only get "command not found". Now, I basically have no idea what to do.
Which recovery should I flash? And how?
I'm so looking forward to your answers.

What you get is the stock recovery.
Flash 4Ext recovery or Amon RA recovery ( fastboot flash recovery recovery-RA-passion-v2.2.1.img)
Among the several guides to install JB, I suggest you to look at the following post:
http://forum.xda-developers.com/showthread.php?t=1804571
I just finished this morning the following process:
install RA recovery,
install Blackrose and resize partition,
install from SD card Evervolv-Perdo-3.2.0-Nightly-2013.01.13-passion.zip
install from SD card gapps-ev-jb-20120816.zip
I spent a lot of times reading and trying. I had an issue after installing Evervolv-perdo-3.1.0final-passion zip. That's why I switched to the Nightly (JB 4.2).
Once you are set install a2sd from within the terminal emulator on your N1.
In my opinion this is so far the best ROM I ever have had on my Nexus 1.:good:
I am impressed to the extend that I offer to my wife to do the same on her N1. She said no. No to unlock, no to root and of course no to custom ROM.
Good luck

Hi,
thanks for your reply. Thats basically what i did as well. But after using Blackrose i can't go into the recovery mode.
I used the same tutorial. The problem lies here:
"Note: some people have reported having problems getting into recovery at this point (if not move on to step 5). If that happens, luckily for you, 4ext put a recovery image in the downloads folder of your SD card and if you did what I said in step 2 you saved it. Try reflashing that recovery image using fastboot (remember the one that was in SD/Download/4EXT_Recovery_Touch/ and was named "recovery.img"). Put your phone into the bootloader by turning off your phone, turning it on again while holding the trackball down. To reflash the recovery open command prompt and cd to the location of the Android SDK tools. Then type in the following command (replacing "path" with the path to where the recovery image is located on your computer):
Code:
fastboot flash recovery /path/recovery.img
If that does not solve your problems (inability to get into recovery) then I would recommend going back to the cyanogenmod wiki and installing Amon_Ra's recovery. Then you can use it to flash your installation zip."
It seems like I am unable to understand what I am supposed to do. Could somebody give me a step by step advice? I would prefer using some other recovery.img than mine...

In other words open your folder android-sdk-windows installed on the root of your C: hd. Click on the folder platform-tools and download Amon RA recovery in this folder. Left click anywhere on a blank area of this folder then press the key Shift (keyboard) and right click your mouse. In the drop down menu select Open command window. In the CMD, to be sure that the N1 is recognized by the pc (meaning the right drivers are installed) type ADB devices and press enter. You should see a string of numbers like HT9C......
Type adb reboot bootloader and press enter. You are in the fastboot mode ( and mood if I may say so) and the phone shows that it is in the bootloader. You can check again that N1 is recognized by the pc by typing fastboot devices. Same string appears.
Type fastboot flash recovery recovery-RA-passion-v2.2.1.img.
After the installation is completed boot in recovery, select Flash zip from sdcard, select the ROM you have dropped on the card. When the installation is completed go back to Flash zip from sdcard ( you are still in recovery mode) and select the gapps you have dropped on the sdcard.
Go back to Reboot system now. You are then out of the recovery and it takes some times for the N1 to boot to this beautiful JB

As c2med posted in his guide, sometimes, people lose their recovery when they repartition using Black Rose. Hence, its always best to have Amon-RA or 4EXT flashable .img file in your PC so that incase you lose recovery, you can always flash it back.
Once you are in bootloader ( also called FASTBOOT mode) you can flash your recovery.
Then reboot into recovery from FASTBOOT (Shutdown and then restart using the recovery combination)
Once you are in recovery, follow the steps in c2med's guide (wipe cache/dalvik/etc - except sd-card ofcourse) and flash your ROM from sd card.
Then reboot into JayBee

In the screenshot you type:
$ ./fastboot devices
then you type:
$ flash recovery ......../recovery.img
Command not found.... Sure, flash it's not a command...
You need to type fastboot command first!
$ ./fastboot flash recovery ......../recovery.img

Thank You! That's what I figuered out last night. Of course I also tried "fastboot flash" but forgot the "./". That was the key. Now the JB ROM works like a charm.
New Problem:
I can't install google apps. In fact I don't really need them. I only use a few apps and found the .apk files with google. Unfortunately the "official" Google apps like chrome don't work.
Plus, I wanted to install the camera (laggy in the evervolv - rom) and keyboard from here.

When I try to install the .zip files in recovery mode I always get an error because of the signing... any help?

When you're in recovery, select "Flash zip from SD card" and then select "Toggle signature verification" to disable signature verification, and then "Choose zip from SD card" and navigate to the zip file that you want to flash.
