G1 shuts down on Android splash screen

I'm trying to fix a friend's G1, which he bought on ebay from US.
I've no experience whatsoever dealing with Android, so this is new. But I'm fairly capable of understanding every technical process you could use, so I think I'll understand your explanations.
Whenever I connect the device to a PC via USB, the computer detects an unknown device, but the phone just restarts at the splash screen. Notice that it has two different behaviors: When there's no cable connected, it just shuts down after 2 or 3 seconds at the Android screen; when I connect a USB cable, instead of shutting down it restarts continuously.
The first thing I did was to unroot the phone and put the official RC29 rom. Unfortunately, the problem persisted.
I have access to the recovery menu and the bootloader (I don't know if this is the correct term, it's the Camera+Power menu).
The major problem (I think) is that I don't have access to the console, as the recovery menu I have is the original one.
So, can anyone help me with this? Thank you.

Options:
Root the phone and use a custom recovery.
ADB also enables use of the terminal through the shell command. -- You could also use ADB to get a logcat and see what happens before the reboots.
But I don't see how the terminal would help, it sounds like hardware failure if it does it with a stock and custom rom.

Don't I need access to the OS in order to root the phone?

Which SPL do you have?

A boot loop or crash at startup can be caused by many, many things.
Get hold of the android sdk.. inside the /tools folder are 2 programs called ddms and adb, you can start the phone while connected by usb and use either of these programs to grab a startup log. Post the log here and we can hopefully see what's causing the crash.
You probably shouldn't have unrooted the phone.. that's going to make things more difficult.

adb and ddms can't find the device. There's an "Android Phone" in the Device Manager, but as the phone keeps restarting, I guess it isn't on enough time to be able to be detected by adb and ddms.

Did you install the usb driver that's packaged with the sdk? the one windows installs by default doesn't work for adb or ddms.
If you've got this driver installed and ddms doesn't see the phone, that's pretty ominous.. it should show up there as "offline" as soon as you power it on.

Thanks, I fixed that and I got the ADB drivers, but the same thing happens. I can't get the attached devices, nothing appears on the list.
One note: this last time I tried to connect the phone via USB it booted, but I couldn't sign in, because as soon as I slid the keyboard, the phone shut down.
So, now I have a "Android ADB Interface", but still no devices listed with adb device.

Right now sometimes (like in 40 tries) the phone turns on and I can use the touchscreen, but when I need to sign-in, it tells me to slide the keyboard and it shuts down.
I still can't get the attached devices using adb, even after trying in other computers.

what happens if you start with the keyboard open?
you know, it could be a hardware fault, a dry joint or loose wire
the sliding of the keyboard just jolts it.

[Q] Bell Vibrant, black screen, no recovery

I've read several topics but i couldn't find the right answer. I hope you can help me.
The problem i have happened without me doing anything recent. I have never flashed any rom, and i rooted my phone for titanium backup like 2 month ago and it worked fine.The last things i did was to install pocket legend, the new mmorpg like 3 days ago.I charge my phone during night, and take it for the day in the morning. Today, the screen stayed black when i picked it up. When i reboot, the screen goes black after the samsung logo.
The problem is that i have recovery mode (the 3 buttons) disabled and when i try to connect to kies it says i am not in samsungs kies mode.. Is there a way to force it to detect my phone so i can try update it?
According to the wiki, my phone doesnt seem to be bricked as i can still see the battery charging when i plug it. Is my phone bricked? Any hope?
I know the easiest way would be to return it to the store, but i dont want them to see my personal information/rooting as i cant even factory reset it.
There is also that topic on internal sd that has failed but i think this is not my case. You can still boot into android without the internal sd right?
I've seen a topic on soldering two mini usb cable to force the phone to go into recovery mode. I not familar enough to do it. If this method could solve my problem, could anyone sell me one?
Was there an over the air update today that could've done this to my phone?
I am lost, please help i am really clueless in what is happening to me.

are you able to go to download mode
flash your phone that way with odin i had the same problem as you

download mode as in using the 3 buttons? no i cant unless there is another way?

I can't get odin to recognize my phone.. I can't get into os so no usb debugging...

then it'll help you flash back to whatever you want

Okay, I know the jig will DEFINITELY work in this case. Any phone state I've come across with that jig, I can throw the phone into downloading. However, it seems that there MAY be hope for you PRIOR to using the jig. Are you familiar with the ADB commands? If so, turn on the phone, connect via USB, run cmd as administrator, navigate to the proper adb folder and under the prompt type in adb devices. If it shows any device, type in adb reboot download and it'll throw it into download mode for you.

Good to hear that the JIG would work. As for ADB commands, doesn't it need the usb to be put in debugger mode? Is there any way to do it externally, without going in the setting menu? I am not very familiar with the adb commands but if its doable i will go read about it.
Thanks for suggestions!

exactly... it's not possible via ADB in your conditions

Thanks you for help!
I still tried but it said that it couldn't find my phone.
I leaning toward making a JIG. I just have to figures out how if no one sell them

Did you really tryed Download Mode?
"Vol Down" + "Home" + "Power" instead of "Vol Up" + "Home" + "Power"?

I tried several time different combo listed on wiki without any success. About 3h long!
I bought my phone the first day it came out so i guess the hardware method is locked.
As soon as i can get it back running i will apply that new fix for the combo.
I am a bit worried about the homemade JIG, will it still work without usb debugging?

Where in the world are you?
If you are in the GTA area, then you can invite me for a coffe

Yes. It will. As long as the phones off and the jig is in when you turn it on

Thanks you for confirming this! I ordered the components and i will try to do it myself.
Some people have done it without any solder skill ! I hope it get here fast! I didn't know i would miss my phone so much!

Seriously! ??? I just soft bricked my phone I really don't know why these software and hardware companies can't get this right the first time. I was going to by an iphone until a sales rep showed me the galaxy s and I was impressed until I saw the black screen of death. A whole lot of B.S. to fix something that should work right in the first place. I'm getting tired of faulty equipment.
My Galaxy is still under warrenty I'll bring it back to store but I'm fed up with worthless technology.

black screen help plz
hey guys i have a galaxy s vibrant which will turn on nd the home nd back nd other buttes will turn on but my screen wont any idea what it might be ?

[Q] Sprint Hero boot problem

Does anyone have any idea why a Hero would for no apparent reason while sitting on a charger go into a reboot cycle only bringing up the htc sign and then the phone with triangle and exclamation point and do nothing else? the phone has never been rooted or anything just did that on its own.
Would running the Regawmod rooter exe possibly fix this?
Also i have another Hero i was given that i have tried to run the rooter on but everytime i do i get the error "Necessary HTC drivers are missing".
i have tried three different versions of HTC sync since i don't know where to get the drivers seperately. all with the same result. any help will be greatly appreciated.
Thanks in advance

Tap my avatar or search the hero dev section for my thread on how to install adb. Try those drivers and see if they work for you. If they do then try the hero rooter or run the ruu.
#Root/Hack-Mod_Always*

no luck. still have the orange triangle and exclamation point, tried the ADB thing and its not recognizing that the phone is there. but when i plug the phone into the computer it acts as though it is mounting as an external drive but when i click the drive letter it says to please insert a disk.
when i try holding the home and power button i get an error at the bottom of the screen that reads "E:Can't open /cache/recovery/command"

Ok what steps did you take?? Details please?? And when you setup adb did you type adb devices??? And how did you go about setting up adb???
#Root/Hack-Mod_Always*

i went through the steps in your post minus the mobile stream tether and i can't enable usb debugging because the phone will not boot up at all. it has been this way since last night. was just sitting charging and then went into a reboot cycle only bringing up the HTC logo then after awhile of that ended up at the screen its at now with the phone with the triangle and exclamation point.
i did type adb devices but it didn't come up with anything in the list of attached devices.
Edit: i did put the easy tether on the computer but since i can't access the usb options on the phone i can't set up the debugging. i don't know whats up with the phone

The mobile stream steps were the android drivers I originally suggested you to try. So try those drivers and see if they work for you. I posted that thread for users who were having trouble with the htc drivers
#Root/Hack-Mod_Always*

ok well i hooked up the working hero so it would install the drivers, which it did, then i hooked up the hero that is stuck for no apparent reason on the error screen and i was finally able to run the regawMOD rooter but i guess because it doesn't have usb debugging enabled it won't allow anything to happen.
just trying to sort out what happened to this phone for it to be stuck at this error screen. nothing has ever been done to it just happened last night while it was charging

What you're seeing is the stock bootable recovery image. Pulling the battery and powering it on again should make this go away. Have you already tried that?

yes have already tried this a couple times, now it just sits at the phone with triangle and exclamation point. won't do anything else

well took the phone to sprint and they deemed it unsalvageable so i guess this is moot. he tried all the standard resets etc. so thanks for all the help but guess the phone is a brick now. wouldn't replace it because the moisture indicators had been tripped.
youd think there would be a way to reforce the OS onto the phone to try to get it going again.

If it was sitting on the charger and went bad, perhaps your charger fried it in some way. Sorry to hear your loss, but look it as an opportunity to get an better phone

Accessing pictures with broken screen

Hey guys
Last night I broke my SGS's screen. The phone is rooted and I know it still works as can hear it get texts and boot up correctly.
I wanted to just swap the phones out but I have a lot of valuable pictures etc on the phone that I hadn't backed up yet.
Is there any way to access the hard drive from the computer w/o being able to access the phone?
I tried the "Screencast" app but I cant seem to get it to work. I tried doing some searches on here but I'm not exactly sure what to look up.
I have insurance on my phone so I can get a replacement, I'd jsut like to get my pictures and any text messages i may have missed (but mainly the pics)
Any insight you guys have would be much appreciated.
Thanks in advance!

Reboot in recovery mode. That would give you adb access to the phone and you can adb pull your pictures with "adb pull sdcard/DCIM/Camera".

thanks for the reply.
sorry i'm kind of new at this stuff. my friend rooted my phone and did all the dirty work. i have no idea how to use adb or w/e
do i need a linux machine? also, how can i reboot in recovery mode if the screen is completely disabled?

do get via ADB you need to ADB kit or the Android SDK kit, theres a helpful section on how to do ADB but it shouldnt be a problem, i also recall that after ADB is installed you might be able to use Android explorer to go to the phones pciture directory and get them like that?

i'm having a horrible time trying to get this setup lol
i think a problem i'm having is i dont know if USB debugging is enabled on my phone, and since the screen is broken i can't turn it on.

anyone else have any other suggestions?

it seems i can get it into what i ~think~ is recovery mode (it didnt make the typical noise it makes when booting up, and my bottom row buttons light up if i press the power button then one of the buttons)
not sure what screen im in honestly... but even still, the computer doesnt detect that anything is plugged in and ADB doesnt detect any devices...

maybe with usb cable?

thats what im doing is using USB cable.. problem is i cant mount my usb from my phone as the screen is broken.
i cannot do it blind either i dont believe, i dont think the screen is detecting my fingerpresses at all

Broken Display Question About Data Recovery

So I shattered my display and the screen wont turn on but it still vibrates when i get notifications, i was wondering if anyone would know of a way to sort of project the display onto a TV or PC so i can use apps that i installed to backup messages and app data and stuff?

I'm pretty sure if the phone still works you can run it in ADP on your PC and basically click through the phone. Then do whatever you need to do and back it up.

Here's the problem with that:
ADB doesn't work unless you first enable it in developer options. Once you do that, you have to click yes on a confirmation dialog the first time you use it. Both of these processes require a functioning screen.
If you have an unlocked phone with TWRP installed, and you can blindly convince the phone to boot into TWRP (maybe by booting into bootloader and using fastboot reboot-recovery, but I'll have to check and see if that command works when I get home. I think it does.), you'll be able to access the data on your phone by simply plugging it into a computer. If you do not have TWRP installed, and you have no lockscreen set up (no swipe, no password, no pin, no nothing), you might be able to access the data by plugging it into a computer after it boots.
If none of those situations apply, and the data is worth about $100 to you, you might want to look into a screen replacement service. Sometimes you can find little electronics places in malls or shopping centers that will do it, and I'm pretty sure there are businesses that you can mail your phone to and they'll mail it back once the work is completed. A friend of mine even found a service that sent someone to her house to replace her screen then and there.

Thanks, booting into TWRP worked and I was able to get most of the stuff I needed. I completely forgot I could get into it that way.
