Help needed to fix rooting gone wrong

First off im sorry im adding another rooting post to these boards.
So i decided to root my 32B magic today copyed the recovery.img over and update file from the rooting wiki, loaded recovery mode then updated, but now my phone when turned on loads to the vodafone screen and freezes id left it for afew hrs but still no luck.
Here is what i know so far:
I am able to get to fastboot and fastboot usb
I cant however get to recovery mode by pressing menu+power
I can get to the recovery mode using the sdk\tools
my problem is that im sure the fix is relativly simple i.e. load some files onto sd and start again, but the problem is that i have no other way to load the files onto the sd card than through the phone and my knowledge of adb isnt that great although has improved greatly today lol.
Im not sure how correct i am on this, but would it be a possible fix to load say a rom update.zip onto the sd card and load that through recovery mode to bring it up? If that would fix it could i possible get help on the adb code needed to pass the file from computer to the phone through fastboot usb or recovery.
Thank you very much for your help

Ok i think i have figured how to push files to my sd card however whenever i try it come up saying Failed ( remote:signature verify fail)

ok well i managed to move Cyanogen's newest rom over and update to that but its still hanging up at the vodafone screen upon booting, im lost for ideas.
Please any help how ever small would be amazing right now.

please help is desperatly needed.

i am having the same issue.... and it seems NO ONE has a bloody answer to why it is failing

I successfully update to 32A and root. Then i tried to update to MT3G OTA rom and now i'm stuck at Vodafone screen. Need help or ideas and how to recover..

i had the same problem, what i did was that i found a sd card adapter and hooked it up to my computer, its pretty quick and less hassle

take out your battery and after a few seconds put it back in, before it powers up go into fastboot(back+power) and that should do it

I still have a pretty red splash screen and stucked.

I have same problem, but your solution didn't work for me.
I did as follows.
#1. typed following command in terminal.(well, I'm using Mac)
Code:
fastboot-mac flash recovery recovery-RAv1.2.0G.img
#2. pulled battery off from phone.
#3. pluged USB cable to phone and also Mac.
#4. pressed (ENTER) in the terminal, then fastboot-mac said '< waiting for device >'.
#5. put the battery in while pressing (back)+(power)
#6. then, pretty red vodafone splash screen come up.
#7. In the terminal, it still said '< waiting for device >'. Nothing was changed.
#8. On the phone, pretty red splash screen was still there. Nothing was changed.
Those are all I have done many times for last 2 days.
But, it didn't work.
Please let me know if there is something I missed.

I tried and stuck in the exactly same problem as [robotician]. I have MT3G.

THe red vodafone should not come up. You have to hold the back key longer perhaps, because it's supposed to go into the fastboot screen with all sorts of text and three androids on skateboards at the bottom.

@Niaski
was your rom made for the 32B or the 32A?
They are very diferent phones and mixing the roms causes the issue you are seeing.

DREA100 and the infamous Triangle of death?

Ok.. So a friend of mine suddenly got a triangle with the exclamation mark picture on his phone. That's all it boots up to. So, he took it to T-mobile, they told him it's FUBAR, and sold him a new phone.
The fact that the thing boots to a recovery mode tells me that there's SOME way to un-FUBAR this phone. My friend is too technologically inadiquate to attempt to do any modifying, so I'm going to assume he was at whatever firmware level would hve been blasted out to T-mobile as of last Friday 01/15/2010.
If I boot the phone normally, it gives me the TriAngle. I pop open the keyboard and hit alt-L and the I get the Android System Recovery menu. at the bottom I get "E:CAn't open /cache/recovery/command"
I've spent all day bouncing around this forum, and many like it, downloaded all sorts of G1 fimwares trying to go back to RC29, RC28, 30, 33.. gah! The latest one I'm trying to update to is "signed-kila-ota-116143-prereq.TC4-RC19+RC28+RC29.zip" Which i rename to update.zip . I hit alt-L, select 'update from SD card' It goes through:
--Install from sdcard...
Finding update package...
Opening update package...
Verifying update package...
Installing update package....
Installation aborted.
That's it... no more log than that.
I've done the Alt-W, and Alt-S.. wiped cache partition. I think playing around with the recent firmwares might be fun, but I'd like to get this bad boy reset back to factory defaults. I've read the forums here on how to do that.. but all of the procedures fail.
I can get Windows 7 to recognize the phone, but I cannot access the sd card while it is in the phone. I've been transfering data to it by taking the sdcard out, and putting it into a known good SD card reader. I've formatted the sdcard to FAT16, and FAT32 quick and not quick.
Seriously.. why is this so complicated? Now I need some serious digging assistance. Is there an interface that will allow me to directly talk to this phone via the USB cable? How can I force an firmware onto it? Clearly something is functional, or I would get no I/O. How can I get this silly thing back to where it was? I know this thread seems like a redundant one, but as far as I can tell, its not. The typical procedures posted here don't seem to work, but I'll be happy to run through any steps y'all suggest. I'll resign that it's been bricked if that's really whats happened.. but I'm not ready to throw this unit away yet.
Ask questions.. let me answer them. I know this team can get this phone working again.
Thanks y'all.

bingo !
sounds like your friend tried to flash something he shouldn't have. or messed around with stuff he shouldn't.
as far as taking it to the store, and accepting their suggestion to "GIVE US YOUR MONEY!" that was a mistake.
the phone is likely fine, and maybe you'll buy it from him for cheap, then fix, resell/use.
good luck, should be easy.

The "press camera and power to get to bootloader" procedure. I've tried holding the Camera while pressing power over and over and all I get is the triangle. However if I press power and the "back" button (swooping arrow to the left), I'll get the bars screen, and a Gray screen telling me to press send to restore.... Which is all good, but there's no progress or any thing to indicate that i've done something by pressing the send button.(based on cell phone standards, I'm assuming "send" is the green "call" button.
Is this normal?
No yeah.. he gave me the G1.. its mine. I just need to fix the little bugger.. .. well.. then laugh at him

Ok.. one more day (well ok.. couple hours) of fiddling with this thing, and i'm begining to wonder if Microsoft was involved. I'm not able to get this poor G1 to do anything new. I tried using a different SD card, hoping perhaps the one I got with it was bad... no dice. camera + power doesn't do anything useful.
I can connect it to the PC.. but i can't see the data card that way. adb devices reads no output, so its not correctly attaching to the PC (tried Windows 7 32bit, and Windows XP 64bit).. There's gotta be a good way to force a known good image onto this silly thing.
Is it probable that the internal memory has gotten corrupt somehow? I know someone out there's got the golden suggestion, please do tell if you do. I'd really like to use this phone.
--Rob

If you can get into fast boot (the tri color screen) there are ways to flash it... try getting into your tri color, then plugging in the USB cable and see if it switches from Serial 0 to USB at the bottom, if so you are golden to flash using the fast boot method.
There are guides around on how exactly to do that, as well a couple places that you can download the official RUU that will do all the hard work for you!

gah.. nothing doing. I can hit Back and Home, and end up with the tri-color screen for about 1/5th of a second, then a gray screen saying:
This operation will delete all your personal data, and reset all settings to manufacturer default. Press Send to restore manufacturer default, or press other keys to cancel.
At this point, the unit is dead. I can remove the battery, and continue on my little quest.. but hitting *any* key at all (including the Send key) will not produce any sort of output. I've tried pressing Send one time, then setting the phone down for a full hour (watched a netflix show) nothing. I can't power it off either w/o removing the battery.
I would throw in the towel.. but from all the research i've been doing, it seems as if this one is behaving in a manner in which other forum users havne't posted. Maybe by continuing to try options and post results, a positive outcome will come out, and someone else who has a G1 behaving this way will have an easier time.
... or y'all can tell me that its toast and to bugger off.. ha ha.. either way.. I continue to google. If you can think of anything, please toss it out.
OH!.. tried an RUU.. found one called. RhodiumSPLRelocker Looks promising.. but can't see the device when attached to the PC... yeah.. guess the phone has to have a functioning OS before that will happen...

You would want a Dream RUU... I looked around a bit and couldn't find one. Maybe someone has a quick link?
Double check that your SD card is formatted FAT32 and see if you can get ADB to see it when on that greay screen.

I've formatted the SD card in FAT32 multiple times.. I even questioned if my Windows 7 32bit would do it, and formatted it on a laptop running XP 64bit. adb doesn't seem to see it ever.
I don't get why I can't get it into fast boot. I've been looking on ebay for dream G1s with broken screens.. heh.. I guess i'm preparing for the worst. really sad, becasue this G1 was actually pretty well taken care of. My friend didn't do anything he shouldn't. HE woke up one morning and it was like this. He lives out in the country.. so he gets pretty spotty signal. I'm wondering if T-Mobile didn't push out an update, and it got interrupted by signal loss.
By the by... I've been doing all this work w/o a SIM card. Does that matter?

its not the green send button -- its the red end button
see below extracted from http://theunlockr.com/2009/07/05/how-to-unroot-your-t-mobile-g1/
Load the DreaIMG.nbh File
1. Download the Original DreaIMG.nbh file:
http://www.megaupload.com/?d=XXSQ0T7W
2. If the file downloaded above downloads as a .Zip file, please unzip it first then put the DreamIMG.nbh file that is inside on the SD card, NOT in any folder. (If you did Section I the phone is off still, take out the memory card, put it in the MicroSD adapter and plug it into your computer to transfer the file over, since your G1 won’t turn on right now if you did Section I above. Otherwise if you did not need to do Section I above, then you can just put it on the SD card normally using the usb cable and the phone).
3. Turn the phone off if it is on.
4. Turn on the phone by holding the Camera button and the End key until the bootloader screen turns on.
5. Hit the End key to start the update. DO NOT INTERUPT THIS PROCESS.
6. Once it is done, hit the trackball to restart the phone. You now are on the stock firmware RC29

You mention that you can access fastboot by pressing the back button while turning it on, isn't that how the hero gets into fastboot? maybe your friend tried flashing a rom that was meant for the hero. if you have access to fastboot you should be able to flash a new image from there, just place the image file in the root of your card and follow the fastboot instructions

Also if fastboot isn't doing it for you have you tried adb? if you don't know what that is look it up I've seen a couple guides on how to do it and they are really detailed.

Im having the same problem, Im stuck in the recover triangle of death. Ive done the alt+w and reboot, the RC29 DREAIMG.nbh , the update.zip, camera+power, I cant get the gray screen to pop. Nothing, its brickkkkeeeddddd, FUBAR. There has got to be someway I can reload this G1. I wasnt trying to root it or anything. I was bowling and then it triangled on me. Anyone have any ideas at all on how to fix it?

Triangle of Death
I'm from Brazil, I can't take it to t-mobile to fix...
when i tried to root my G1 did the downgrade perfectly, the screen was just as it was suposed to be.
But in the recovery mode boot, appeared this triangle with an exclamation...

The only idea I have is make'ing an goldcard so your sure your phone accepts the update (dreaimg)... other than that...
Sent from my HTC Dream G1 using the XDA mobile application powered by Tapatalk

Any chance the home button is stuck? I'm not 100%, but I think if you were to hold home, camera and power, the recovery would come out on top.

Home button is not stuck, and cant seem to figure out the CID of my SD card since my phone is unaccessable.

PLEASE help! STUCK ON "X" SCREEN!

I have a N1 and its worked fine for a while then i noticed when i turned it on it just stays at the "X" boot up screen.. I have already tried to reset the phone, clear storage, reboot,, and nothing fixes it. What can i do.. i know there has to be a way to load software back onto it or fix whatever is wrong with this thing. please help and thanks for our time.

can you get into the bootloader menu? by holding trackball and power button?
if yes then follow

another app2SD thing after flashing a new rom?

well then you know more then me. If you can get into bootloader you should be able to get into recovery mode. You can also toggle USB mode, so you can be connected to your comp. In that case you can push a recovery image.
http://forum.xda-developers.com/showthread.php?t=611829
you can also wipe
etc
its all in that thread or somewhere else on this forum

Any updates? same thing happened to me.
If in doubt then reflash everything again;
boot
system
and recovery
and start afresh.

see thats the thing,, i can click recovery from the bootloader screen and nothing happens. It will restart and just sit on the same "X" screen. Its very simple to put a phone into a DFU mode or recovery mode for Iphones,Motorolas,blackberry,nokia,samsung,Lg, and a few more i cant think of at the moment. When these phones become corrupt ive learned how to whatever firmware or software i want on dumb thing.. But this HTC is giving me a hard time and i know its something simple.. Most phones have a desktop software that will allow you to mess with phones programming, Itune-iphone/Blackberry-BB desktop Manager/motorola-RSD lite....ect. BUt i cannot find anything really for the HTC or just this N1. A lot of these programs for other brands, once you plug your phone in, will notice that the phone is in a recovery state and offer to do an update or a restore. Now why doesnt the N1 or do they, does google offer something like evryone else does?

hmmm I understand your frustration. What did you do before it got to the 'X' splash screen?

The SDK can do that
like the others said, try get into recovery and reflash everything

SDK? i just turned the phone on and its stuck on the "Splash" screen just a big ol "X". I press volume down and power and pull up the bootloader menus.. i scroll down to recovery and press enter. and it reboots and stays at the damn "x" screen again. I've chosen everyone of the options it offers in that menu and nothing changes.. You know how when u first open that menu it will scan the SD card? Well it shows up for a second then goes away, and in the split second the green lettering is on the screen i swear it says "no splash image" or something like that. UHHHHhhhg!

Hmm I forgot how to get to get to recovery using physical buttons, sth like: power + trackball, or volume down + trackball i guess, so try that
So it looks like your phone is not rooted and you don't have Amon_Ra recovery maybe you have not even turned on USB debugger? tough luck friend

All is not lost if you can get into fastboot mode trackball and power together then using adb reflash boot,system and recovery images.

Or call Customer Service and trade in for a new Nexus One
if not you have to download the SDK http://developer.android.com/sdk/index.html
find stock images and reflash like the above post said

agreed....if you haven't "unlocked" the bootloader then i wouldn't bother with any of the suggestions....Call customer care and get a new one before you un-lock it and this mysteriously happens again...THEN, you'll be S-O-L!!
EDIT: Then with the new one, follow all the threads for un-locking, flashing recovery, nand,flash cyan, flash gapps LALALA
DOUBLE EDIT: Althought it sounds all you've done is messed up the recovery image, which you could re-flash. Then you could get into recovery and flash Cyan, having a functioning phone again

Nexus s stuck on "Google" icon when i start the phone

hi, my phone has stuck on the "google" icon when i start it. I have tried the "bootmode" you know when you hold volume and on/off button. There i tried to push on "reboot", "recovery", nothing is happening same thing. The only thing i have managed so far is installing driver usb for android phone in my computer, but i cant find the phonefolder in "My computer" to put reboot/update files to make the phone work.
How can i make the phone work? please help me im not so good at this.

Check the links kenvan posted above.
You don't want to see the phone mounted as USB, you need to see it with the fastboot command from your DOS or unix terminal.
Then push ClockWork recovery to the phone.
From CW recovery you should be able to use it's tools to get you running again, or at least adb should work so you can mount storage and push files to it via adb.

I'd love to help you but I need a little more background... did you just buy the phone and this is happening? Or did you try rooting it and this is happening? Or did you just flash a different rom and this is happening?

Ok since you say you have a padlock on the boot screen, I assume you know how you unlocked the bootloader.
Turn the phone on into fastboot (hold power and volume up), then connect the phone to the computer via USB. Flash clockwork recovery (3.0.0.5 preferred) and then you should be able to enter clockwork recovery assuming you did it correctly. Push this rom (http://forum.xda-developers.com/showthread.php?t=884093) to your card and flash it in recovery.

Yes i know, can you be more specific`? step by step? im noob sorry for bothering you., how do i push to my card?

I have fixed my phone, my phone was liquid damaged. So i putted the hole mainboard in 100% alcohol and after 20 min i took it out and let it dry. And then it worked fine!

It just happened to me an hour ago. I tried for a few time to remove the battery and start it up (even with a new one). I also thought it might happen since the battery was drained so i let it recharge for a while with no success.
Eventually i attached the device to the computer's usb, waited and started it. and it worked.
Don't know if that was what solving it - but it back working.

Bricked out of the blue.... how to unbrick it without access to recovery?

My HTC U Ultra suddenly froze past nigth, then it rebooted... and never came back, it won't go past the HTC logo over and over. I am not able to enter in recovery mode either, the only thing I can do is, by pressing both volume buttons and power, entering in what seems to be fastboot menu. In that state I can send the phone fastboot commands (no adb commands though) but If i try to wipe it it says "unable to do in s-on" or similar. I was pretty happy with this phone, and spent a few bucks in a new battery not two months ago.... anything I can do?
Thanks.
PS: I failed to state that the phone is stock, not unlocked or rooted.

If it has just happened out of the blue and you haven't been doing anything with your phone, have you tried a simple reset? (Press and hold volume down and power button until your phone vibrates - Usually about 20 seconds for me)
If not, and you are struggling to get into recovery etc, see if you can follow the method in the thread linked below if you are currently on stock rom!?
(Not sure if this would delete all your data or not, so perhaps only use as a last resort....)

Reset doesn't work, and the other procedure didn't work either.
If I leave it plugged to the charger, it will fall into an endless reboot loop. Sometimes (few) it will end up booting, but If i try to do something with the phone it doesn't respond and reboots again.
Thanks.

As you can send fastboot commands, can you flash a recovery.img (i.e. TWRP), and then wipe cache and dalvik/art to see if that helps, but if not, flash corresponding rom to that which you already have?

I tried that, too, but didn't work. If I do a fastboot devices it detects the phone, but if I do a fastboot getvar all it doesn't give me any information, it doesn't admit adb commands, when I try to flash a rom or a recovery, it fails, I suspect it needs to have the USB debugging enabled, but I can't enable it in this state.
As I said before, if I leave it plugged to the charger, It will randomly end up booting (it can happen in the third loop or in the 50th), but it will freeze or reboot again in few seconds.

Ah I see, if you haven't got USB debugging enabled then I am unsure how to help sorry. Have you got your media backed up, or stored on micro sd? If so, might have to bite the bullet and do a factory reset. Sorry I couldn't be of any help. Maybe someone else would be able to help you further?

The data is not a problem, every important file has been backed up.
Regarding factory reset, since the device won't go to recovery, I can't see how can I do it.
-- Edit --
I noticed that when the phone is cold, those few times it boots, it lasts a little bit more (a matter of seconds) until it freezes again, so I tried to leave it in the freezer for a few minutes, and tried to boot it, and had enough time to do a factory reset. The factory reset worked, because now, when it boots, it goes straight to the intial setup, but keeps hanging after a few seconds. I suspect that the internal memory was somehow damaged, I don't think there is much left to do...

Is it possible to skip setup in order to get to settings and enable USB debugging so you can install a recovery?
If you can, then it might be an idea to try performing a repair of all the partitions and install a fresh ROM... Just to ensure it isn't a hardware issue!!

I can't see how to skip initial setup... and I don't have time enough to go through it, the phone will hang in 30 seconds or less. At this point, I really needed a working phone, so I bite the bullet and bought a new one... I will deal with the old one later, or I might sell it for parts.
Thanks everybody for the help.

No worries, enjoy your new phone
