Fastboot and SPL - Click Android Development

As i said in this post (http://forum.xda-developers.com/showthread.php?t=657809) my tattoo is stucked on tattoo logo.. i've tried ruu method and fastboot method with no luck, i am able to flash but it hangs on rebooting..
It's possible to bypass the SPL and flash an older older version of the firmware only with fastboot? I am only able to access Tattoo in fastboot mode, no adb..
Thanks

[Q] HELP! Stuck in recovery screen & can't do ANYTHING!

I flashed a new ROM to the phone and rebooted. At reboot, when the first "android" screen comes up it gets stuck there.
If I reboot in to the recovery screen it will go there but I can't do ANYTHING! Can't scroll to a command, can't "Alt+" any command.
At the very bottom of the screen it says:
Build : RA-dream-v1.7.0
E:Error in CACHE:recovery/log
(No space left on device)
HELP?!? Did I finally manage to find a way to brick my phone?
I do not expect that you bricked your phone. What SPL do you have installed? If you have 1.33.2003 or 1.33.2005 installed, you have always he possiblity to go to fastboot mode and flash a new recovery.

I AM able to get it in to fastboot. I'm still a bit of a newbie though, so I'm not sure what SPL I have...? Possibly Danger? How do I flash a new recovery?

Oh! I see in fastboot that I do have 1.33.2005. So how do I flash a recovery? Thanks!
Nevermind, I Got it!! Thanks for the suggestion/help!
1.33.21005 is DangerSPL, so you have the possibility to use fastboot. There is a tutorial here in the forum to setup adb and fastboot. Unfortunately I do not have the link at the moment.
If you have setup your fastboot environment, you should be able to flash a new recovery with the following command:
fastboot flash recovery recovery.img
Send from my G1 with HTCClay's UNOFFICIAL Superfly 1.5 D/S ADS using XDA App
Excellent

I had the exact same issue and this worked from me...using Amon_RA's method:
"via fastboot :
* Requires engineerings SPL!
Code:
Copy recovery-RA-dream-v1.7.0.img to a location where fastboot can find it.
Boot your G1 into fastboot mode (boot while holding BACK)
Connect your G1 via usb to your pc/mac/...
fastboot devices (to make sure that fastboot "sees" your device)
fastboot flash recovery recovery-RA-dream-v1.7.0.img
"
I just saved recovery-RA-dream-v1.7.0.img to the "tools" folder of the android-sdk and ran cmd from there (Hold shift + Right-click in win7).
Rebooted holding home and I was in RA-dream-v1.7.0 without the error.
Click the recovery image link in my sig for more info.
Thanks!!
To all of you that have suggested things, I figured it out thanks to your suggestions!! I appreciate all of your help on this issue!!

Dream fastboot but no recovery

I was trying to improve the speed and battery life on my HTC Dream. I am using cyanogen recovery 1.7.0R. I changed the radio from 2..22.23.02 to 2.22.28.25. I also upgraded the Hboot from 1.33.2005 to 1.33.13d. After making this change the phone hangs at the boot screen and will not enter recovery mode. I am able to get into fastboot however when I try to flash a new recovery, radio or hboot I get signature verify fail. Is there hope for my phone or is it finished?

Most likely you did not flash recovery and your "old" one is corrupted. Your should have read here how to update, but nevertheless because you are able to go into fastboot, now you have to start over.
1. Read the OP of ezTerry's thread carefully
2. Check the type your phone to identify the nbh-file you have to flash to recover from your current situation (most likely you will need the orange-xxx.nbh)
3. Flash that nbh file using fastboot
Now you have an engineering SPL and you can flash recovery, radio and the 1.33.0013d SPL again.

Thank you for your help. I followed the link and was able to use the orange.nbh to get the phone to boot then used fastboot to reload a recovery image. Thanks again.

[Q] fastboot signature check failed?

i have the latest radio and hboot for G1 (check sig) and in fastboot mode it says S-on.. now im having trouble flashing a custom splash screen via fastboot and i read somewhere that the S-on may be why.. do i need to downgrade to engineering spl to use fastboot flash method? I keep getting a... <bootloader> checking signature failed! in cmd... but i do have fastboot enabled and working properly..
Did you follow ezterry's on how to install the spl and radio:http://forum.xda-developers.com/showthread.php?t=831139? did u follow these steps for installing the spl?
== Installing ==
(Note: Please Do read the information on the SPL below before actually installing)
1) Take a nandroid backup of your current rom (mandatory if you are trying to move the current rom to the new radio/SPL) to simplify things put any update.zips you expect to need on the SD card now
2) enter fastboot mode
3) flash the files and other operations via fastboot
Code:
fastboot flash recovery recovery-RA-dream-v1.7.0-cyan.img
fastboot flash radio radio-2.22.27.08.img
fastboot flash hboot hboot-1.33.0013d.img
fastboot reboot-bootloader
now you will see you have an s-on boot loader with 1.33.0013d as its version
Code:
fastboot erase system -w
fastboot erase boot
please remember while fastboot erase works; fastboot flash does not so be careful *not* to remove the recovery
4) Boot into recovery
5) install a system from backup or as a fresh rom some options are:

You have a perfected SPL installed on your phone (0013d), so you do not have full fastboot support and you are not able to flash a custom splash screen.
If you want to downgrade, flash the orange-xxx.nbh file from Terry's thread (can be found in my signature) and after that you will have an engineering SPL. With this you should be able to flash a custom splash screen. After that you can go back to 1.33.0013d/2.22.28.25 ... everything can be done using fastboot, so your risks to brick your phone are very(?) limited ...
yeah i figured it out thanks guys!! had to temp flash the engineering spl to do what i wanted.. than jus re flashed 0013d everything is all set thank you guys though!!!

You (as I see was indicated in the thread before) go to the 2708+ kernel/SPL/Radio thread:
http://forum.xda-developers.com/showthread.php?t=831139
This has all the information on the use of 2708/2835 radios and the 1.33.0013d SPL including a section on what to do if you loose access to both the system and recovery in the '== Important Information about 1.33.0013d ==' section [Its important to read that section anyway if you are using 1.33.0013d]
If you still have access to boot, just use flash_image or rom manager to restore your recovery image.

[Q] s-off from recovery (TWRP, CWM)

My phone is stuck in RUU mode (HTC logo and 4 warning triangles).
I can get it to boot CWM or TWRP via fastboot boot. Problem is I'm S-ON with HTCDev unlock, and there's no RUU available for Bell Mobility.
Is there any way at all to get S-OFF directly from recovery? Like, run revone from adb in CWM recovery or something? Alternatively, is there any way to boot a full ROM using fastboot boot?

Why your phone is stuck in ruu mode if there is no ruu for your phone?

I restored it back to stock (or so I thought), but when I tried installing the 4.3 OTA the phone got stuck in bootloop and eventually just stuck in ruu.

What's your problem? Just trolling around, or do you actually have something to contribute??

OK, total stupid moment.
All I had to do was restore a stock nandroid for my CID (found on http://www.htc1guru.com/) using recovery booted via fastboot boot [cwm filename].img.
Then, run fastboot oem boot.
Found last command on: http://forum.xda-developers.com/showthread.php?t=1612969
Guess i got scared by the warning triangles. :victory:
Looks like the "modem" partition is still corrupted, so I have to run fastboot oem boot every time I boot the phone. But, now I should be able to boot a rom, get root, and s-off the regular way.
Also I actually was S-ON with a locked bootloader - managed to do the HTCdev unlock "blind" while in the ruu mode.

system_a error NEED HELP

I tried to flash stock rom through MiFlash with unlocked bootloader and now im getting this and phone is stuck at boot animation. Please help
EDIT: Delete, i get it working somehow.
You must likely were trying to flash your phone while on fastboot, you must boot on EDL mode to flash using Miflash
Format system_a
