G1 when power on comes only G1 screen - G1 Q&A, Help & Troubleshooting

G1 when power on comes only G1 screen, when soft reset and hard reset is the same . when update it says on screen: "E: Cant open / cache/recovery/ command" and aborting upgrade in 50%
Can anyone tell me what the hell is going on with this?

well im assuming the phone has been properly set as far as radio/spl -- i would say you need to reflash your recovery. Erase your current recovery with fastboot and then fastboot the brand new recovery into it and try again. If the phone cant boot into the rom it will try to boot into the recovery and if it cant, it does that. I think. theres a pretty nice G1 wiki here and theres also cyanogenmod wiki... cant go wrong there.

yea i tried to fastboot but i cant get my computer to read my phone it doesn't come up on adb or fastboot i did the <enter>setprop persist.service.adb.enable 1<enter> on the g1 screen but that didn't help either
So i found a couple threads that has helped me

The only problem now is my computer doesn't read my G1. I have the danger spl (1.33.2005) i think
The reason I can't get past the g1 screen is because i forgot to include the rom onto the sdcard before i flashed the radio and spl.
I hope this is enough information for someone to help me
Try a differant driver. The one in sdk1.6 gave me trouble when using fastboot w/ 1.33.2005 spl. Try the one from here it should work.
Once you get that working, just flash a new recovery image. Don't forget to press back to switch to "usb" instead of "serial".

Need help with ADP1 stuck in the SPL mode

Long story short, I've received this ADP1 from a friend, this ADP1 will only boot into a SPL mode when you turn it on.
But at the time, it still has the ability to boot into a fastboot mode, so I mount the RA1.5.2 recovery img to see if it will take CY rom, it successful booted into the recovery mode, and flash the new radio, 1.6 rom along with the CY rom no problem, but when reboots, still goes into the SPL mode.
So here comes the stupidest move...
I've accidentally flash the NBH file(RC29), and was hoping to have a fully restore the phone, but it didn't, and made it worst, now, it still goes to the SPL mode when you turn it on, and now, I lost the ability to access the fastboot mode, and recovery mode only shows the icon, nothing else.
I would like anyone's advise, anything I can try?
Appreciate your help!
Hmm that's a very odd situation. Without being able to boot the phone after flashing RC29 you have no way to gain root again. Sorry to say it but I think you have a semi-unrecoverable-brick :-/

[solved] Unable to boot to recovery

For the last year I have been able to boot to recovery no problem. About a week ago it stopped booting to recovery. Holding home + power brings me to the g1 endless loop. The weird part is it will load any recovery right after I flash it via adb or terminal. I have tried out all the recovery images out there and they all are the same, I have to flash it before I can boot to it and it will only boot once, after reset I have to flash again to get back into it. The same goes for cm updater. I download the update, apply it, phone resets, g1 boot screen infinity... I am an advanced script kiddy and I can't find a solution anywhere any ideas on how to deal with this? Would a log help?
Thanks!

did you try to flash a new recovery.img?
^^
Every time I want to boot to recovery I have to flash. It does not matter what recovery.img I flash (RA, CM, etc..) I stil have to do it every time if I want to boot to recovery. If I reboot the phone or power off cycle more then once I lose the ability to boot to the recovery rom. Its as if it disapears after rebooting or shut down...
Solved...
I wiped and reinstalled cm's latest build. Works fine now. I'm guessing I have to wipe from now on I was really hoping I don't have to.
Thanks

My G1 will only boot up sometimes showing up the screen???

I have never encountered this issue... have been flashing roms for years.. on my windows phones and my G1 since it was possible..
The other day I went up update my phone to the latest CM ROM.. my phone finished and then I booted up the phone.. the screen was black.. i waited for a long time and not even the G1 screen showed up..
I booted again.. and same thing.. i booted again for days and tried getting into the recover with no luck..
I read someone had a simliar issue on here and they went into recover (though no screen or text shows up on screen) and proceded to hit alt w to wipe..i did that aswell and the next boot up the G1 screen showed up. I then did a complete wipe from there and began to install the new HTC recover and CM rom from scratch.. then same thing happend.. i kept getting the black screen...
I then tried to install the original SPL and install the original G1 rom and start all over.. i was able to install the original SPL (which I think is part of the issue) and then turned off the phone.. I placed the dreaimg in the sdcard and went to hit CAMERA and POWER.. and nothing shows up..
I can't for how many times i tried am able to get the phone to go into the install screen from holding down CAMERA and POWER..
I am able to restore the phone using the nanback up from the recover but since I installed the SPL it went away.. not sure if they are connected somehow.. so now i don't have those options either..
Can somebody help me with some ideas on how to fix this?
If you can't get into recovery? To me it looks like a brick phone.
As far as been here and read some post about not able getting into recovery or tri color screen not working as well and not getting any response from phone

I am able to get to the Amon Ra recovery.. and do things from there.. the problem is that when I reboot..it sometimes shows up the G1 and sometimes it stays black..
I tried reverting back to the original ROM by putting the dream on there at that point i noticed that when hold camera and power nothing happens..im' still able to reboot and go into Amon Ra recovery though..
Just an update.. i noticed that my phone only boots up properly if I slide out the keyboard before I press the power button to turn on the phone.. same thing applies when getting out of standby mode while the phone is on...

Phone stuck at 'G1 T-mobile' startup screen, cannot access recovery mode - HELP!!!

Dear android experts,
I had CM 5.0.7 installed on my HTC Dream, and I stupidly installed ROM Manager, wanting to upgrate to CM 5.0.8, and used the application to do a backup - after I clicked the 'backup' function, the phone rebooted, and is now stuck on the startup logo (and has been stuck for the last hour). I have already tried pulling out the battery and booting the phone into recovery mode, however it cannot access recovery mode, and still hangs at the startup logo. Is there any way to get past this startup logo, or is there no hope for my phone? Is there any way to push the phone into recovery mode via adb? I am a complete amateur, who follows step-by-step instructions - please help me!
P.S. If this tells you anything, while my phone is stuck at the startup T-mobile logo, if I plug in the USB cable, a message on a red background appears at the top of the 'G1 T-mobile' logo, saying 'FASTBOOT USB'.
P.P.S. In case this is a detail that could help me, while my phone is in Fastboot Mode, I have four options available:
HBoot Mode
Reset Device
Restart to HBoot
Power Down
Could any of these help me?

This thread is old, and OP is ignorant and wants to blame ROM Manager for his own problems. If you can't get into recovery, chances are you are using one built for another phone. Find the one for the G1.
Or ran into the know issue of cm5.0.7 that fash_image sometimes (more than not) fails.. thus applications using it sometimes fail.
But you have danger spl right? So flash the recovery via fastboot.. and if you don't have fastboot/adb and intended to run these custom roms its about time you installed it.
