No device found ONLY during fastboot - help needed please

I've been reading up about what to do after I tried to "factory reset" my phone and then was stuck at the htc start up soon, which kept looping.
I've been trying to load recovery.img during fastboot (back+power) and then to apply update.zip during recovery (home+power).
However, the problem is that during fastboot, the device isn't recognized (when I go to adb devices on command prompt, no device is listed). I know that my drivers are good bc the device is found when I start up in the recovery mode. I tried to skip the part where I load recovery.img (since when I try to do that, it tells me that it can't be loaded), and to go straight to apply update.zip, but then the phone tells me that update.zip is either bad or can't be mounted.
I have a Rogers Magic (32A). I am a complete newbie, so any help would be greatly appreciated. I should also say that before I tried to do the factor reset, the phone was on the hero rom loaded by a previous user.

try this:
boot in recovery:
fastboot boot recovery.img
then, push update.zip on your sd card ( need a good rom in the tools folder on your computer)
adb shell mount /sdcard
adb push update.zip /sdcard
and apply update.zip with the recovery menu.

thanks for your reply, but it didn't work:
first, it said "cannot load recovery.img"
and then when I tried to mount, it said "mount: mounting dev/block/mmcblk0p1 on /sdcard failed: Device or resource busy"

replace recovery to correct path to your recovery image. (your phone mut be in fastboot mode power with back button pressed)
ex:
fastboot boot c:\sdk\tools\recovery-RAv1.2.1G.img
then your phone must boot on recovery and you could push update.zip

thanks so much. I figued it out - just a simple problem of the update.zip file being corrupt.

Hi. My magic is having the same issues. Although I believe it is my own doing. I was going to create a gold card and I flashed the sappimg.zip, I can boot the phone into fastboot but it us not seen, when I run the fast boot command it just says waiting on device..
I can boot the phone up normally but it does not want to connect to the market our link my gmail account to it..
All to jailbreak... Any ideas?
Edit....
I must have had a poor internet connection last night. I have got the market working.

I am having the same problem.
I have a 32b on vodafone uk.
all the device adb drivers have installed fine. I have tried this on both my laptop and desktop (win 7) and when the phone is turned on - it shows fine under adb devices.
When i boot to fastboot, the phone doesnt show, and therefore i cannot load a custom rom.
Trying to root the phone I have so far used the goldcard method to downgrade to get back to 1.5, if i try to flash the recovery img from the phone (using flash rec) then when i boot to recovery (home+power) it hangs on the vodafone screen - this is why i wont to flash from fastboot.
any ideas?
Thanks

phone rooted?
FlashRec is out of date, I'm pretty sure. Is your phone rooted already, or are you at stock?

Can Not Flash Big Recovery Images (Cm-Amon Ra) Only Jfv1.42

Following the CyanogenMod Full Update Guide, to flash a T-Mobile G1 with the latest CyanogenMod, 4.2.15.1 at the time of this writing, I run into a problem while trying to flash the cm-recovery-1.4.mg.
Basically, when I tried to do: flash_image recovery /sdcard/cm-recovery-1.4.img (or recovery-RA-dream-v1.5.2.img or recovery-RA-dream-v1.6.2.img), I got this error:
mtd: erase failure at 0x003e0000 (Input/output error)
mtd: erase failure at 0x003e0000 (Input/output error)
mtd: skipping write block at 0x003e0000
I even tried (without any luck either):
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
cd sdcard
flash_image recovery recovery.img
cat recovery.img > /system/recovery.img
If I then turned off the phone, and tried to get into recovery mode, by pressing the Home and Power/End buttons, I got into the rainbow screen, and can not do anything.
By trial and error, I was able to flash a recovery image called recovery_RC30_xda-dev_v1.2.img, with an MD5 of 8d055734022496906244b71f849a6b6d, without errors, so that, when I boot in recovery mode, I get:
Android system recovery utility Build: JFv1.42
ALT+S Apply update.zip
ALT+W Wipe/factory reset.
ALT+B Backup.
ALT+X Console mode.
I was then able to flash the HardSPL, by copying a "Hard SPL zip" file into the SD Card as "update.zip", turning off the phone, starting recovery mode, ALT+S to apply, and then rebooting.
After that, I flashed an Android ROM called JFv1.42_RC33, by copying a "JFv1.42_RC33 zip" file into the SD Card, again as "update.zip", turning off the phone, starting recovery mode, ALT+S to apply, and then rebooting.
While all was functioning fine, I still wanted to install CyanogenMod 4.2.15.1.
The problem is that the Full Update Guide states, after downgrading, rooting, and wiping, there are 3 more steps:
1) flash DRC83_base_defanged.zip
2) flash update-cm-4.2.x-signed.zip
3) flash ota-radio-2_22_19_26I.zip
and between 1, 2, 3, it says "STOP - DO NOT REBOOT YOUR PHONE".
So I took the chance, and did 1, 2, and 3. And after each flash, the recovery tool (JFv1.42) would tell me to reboot, which I did.
Basically, I had to mount the phone, copy the corresponding zip file to SD Card, rename to update.zip, turn off phone, turn on phone in recovery mode, ALT+S to flash the update.zip, reboot, and repeat, with each 3 of the zip files.
At the end, I also did the same with the the SPL_Hard_Update_Signed.zip, as it is a G1.
(Basically i did the wiki article, but substituting the recovery.img with the small one, and by having to copy one "update.zip" at a time, and rebooting)
So, while I now have a fully flashed CyanogenMod 4.2.15.1, there are still a couple of doubts:
1) Why can't i flash bigger Recovery Images? Could it be a bad memory?
2) Is there any other "small" Recovery Image i should try that allows me to select the zip and not reboot?
3) Is there a way to do the flashes using the terminal in recovery mode (ALT+X)?
4) If i want to try again to flash CM or RA, and it fails, can i just go ahead and re-flash the recovery image that i have working, or should i need to re-do all again?
5) If, lets say i want to flash SuperD, and i boot in recovery, and flash it, would it be ok, or i would need to do anything else?
Any other ideas/comments?

yaffs2 needs to be -yaffs2
yes, you just replace it, or rename recovery-RA-dream-v1.5.2.img to recovery.img. Also, v1.6.2 is out.
I've never seen the cat recovery.img > /system/recovery.img
I've never had to do it, but if it says do it - do it.
Are you sure you are holding home power? Seems like you're holding back and power or camera and power. Home and power shouldn't do that. By any means. The most it should do is refuse to boot into recovery and just hang on the G1 screen because you either soft-bricked or flashed the wrong recovery.

I have been doing some tests, so i rewrote the first post.

re-wrote it once more.

Anybody has an idea?

have you tried fastboot ?
fastboot erase recovery
fastboot flash recovery recovery-RA-dream-v1.6.2.img
?

Dunno, it seems weird, but I would try and erase it in fastboot and then go from their.
2/
I dont know of any, they all float around the same size
3/
If you build a system.img and what not, you could do.
flash_image system system.img | flash_image boot boot.img etc etc from the console.
4/
Its a risk, but flashing the recovery wont effect the install of cyanogen (or whatever custom build of android you have installed), worse case though is losing recovery if you cant put one back on.
5/
It should be ok.
Dont know how good you are with coding etc... but most recovery images have the source code avalable.
You could rip out all the crap you didnt want and shrink its size like that.

A few guides saw to follow this step if you have problems flashing a recovery image, but it can be risky of course because it will wipe your now working recovery, so if it then wont let you flash the recovery image you now have you wont have one.
The one i have flashed, is about 2M, the ones from CM/AR are about 4MB.

I know that when you compile from source you get boot.img (the boot image) and system.img (the system.img)
you can flash them from the recovery console using the commands
flash_image boot boot.img
flash_image system system.img
etc... if you can find a build that has those images in the update.zip you could flash them manually.
So, if i can not flash CM/AR, i can re-flash the one that worked you mean?

I cant see why you wouldnt be able too, if it has flashed once it should flash again, but given that it may be a hardware fault (I am not saying that it is, but IF it is) then it could be risky.

[Tutorial] Restoring Recovery Mode while working only Fastboot Mode*ALL METHODS HERE*

Hello!
Yesterday I found myself in a very terrible situation. I spend about 6-7 hours...
It just happened that I deleted the recovery (through fastboot), and before that deleted firmware of the phone. That is, there remained only mode HBOOT (fastboot). Around the internet and google there are no guides on how to return
recovery by the alternative methods or how to flash a new ROM through
fastboot.
Thats why i want to present to you my little guide... Coz i think it will be very useful for some ppls like me with the same trouble.
So, if you're in a situation where you do not have Recovery, and the phone is not started in boot ROM then first try a standard way to flash a new Recovery through fastboot mode
Standart way of flashing new recovery via fastboot​
1.Connect your phone with PC via USB and power off your phone (if it up).
2.Than start up in fastboot mode - (in my situation, fastboot mode is CAMERA+POWER, then button "send") in all other (as i know) this is starting the phone while pressing button BACK.
3.Open -> Start->Run->cmd (open command prompt in windows*) and write:
Code:
fastboot devices
Than you must see your device serial number like this:
Code:
H94XTGAMSHDY
and should say "fastboot".
If all right - go next. If not - check fastboot mode (is on?) and USB cable.
4.Than change directory via cmd to where you have saved your recovery image (NEW recovery.img !!! ALWAYS CHECK MD5 SUM)
5. Than type this :
Code:
fastboot flash recovery recovery.img [enter]
(while you are stay in the same dir where you saved recovery.img)
(if you got some error about previously version or smth like this you can try to use this: fastboot erase recovery and only than try to flash new recovery from step №5)
6.Check your phone's display, as recovery is being sent and flashed to your device. And check your command prompt/shell to make sure the process is over.
7.Reboot into recovery by holding Home and Power (before it power off device).
Thats all! You can use any recovery, all what you like. I use Amon_RA's recovery.
IF WHILE FLASHING YOU GOT :
Code:
sending 'recovery' <4594kb>... OKAY [ 1.734s]
writing 'recovery'... INFOsignature checking...
FAILED <remote: signature verigy fail>
finished. total time: 3.125
Use next steps (my Alternative method)
And IF you can't flash recovery by this method it is not big trouble as you think now
Alternative way of BOOTING new recovery via fastboot​ checked and founded by me
Everything here is much easier and faster!
Do not be scared as I did it yesterday
Only what you need it :
Change directory via cmd to where you have saved your recovery image (NEW recovery.img !!! ALWAYS CHECK MD5 SUM)
And than TYPE:
Code:
fastboot boot recovery recovery.img
And your phone will be rebooted about 2 seconds in RECOVERY MODE. Yes!
After this you can use your old Nand Back up (restore it) and start up your old ROM. Or you can wipe all and try to flash new ROM and many operations what you can use via recovery. When you will get working ROM and flash it - you can flash recovery via adb. Or Use Rom Manager (Not recommended!)
Why we use this method? Because if you got error while flashing - FAILED <remote: signature verigy fail> you CAN'T FLASH ANY .img. Why? I Don't know, i hope some android guru's help us with it theory
(ALL AFTER THIS LINE ALL TEXT COPYED FROM WIKI.CYANOGEN.COM CREDITS GOES TO Cyanogen. Thx you, god)
If you want to flash recovery via adb (using power on phone with working firmware) (This method working 100% but strongly need working phone with working ROM)
Working only with HTC DREAM (G1) - Attention.
adb method by cyanogen version
Restoring the custom recovery image
Download the flash_image tool (HERE LINK
Next, place the file on your desktop
Change the directory to where "flash_image" is located, e.g. in Windows: cd C:\<path-to-flash_image-location>, in Linux: cd /home/USERNAME/path/to/flash_image on a Mac: cd /Users/USERNAME/path/to/flash_image)
IMPORTANT: Turn on USB debugging. Settings -> Applications -> Development -> check the box "USB Debugging"
Open up and adb shell
With your phone booted, type the following command
s:
Code:
adb root
This will start ADB as root, or notify if it is already running as root.
Code:
adb remount
This will mount the system partition (/system) as writable, allowing the following
Code:
adb push flash_image /system/bin
This will send the flash_image script into the /system/bin, so we can use it from within the shell
Code:
adb shell chmod 0755 /system/bin/flash_image
Finally, change the permissions of the script to allow it to perform the desired action.
Now that the script is installed, we are ready to proceed with flashing the custom recovery, saved on the root of the SD card earlier:
Code:
adb shell flash_image recovery /sdcard/recovery.img
P.S. If you want i can post here method by flashing original 1.6 ADP Rom via fastboot (but as i think it is on htc dev web... But i can post here cut version of this - coz original version have many not needed things.)

hey ANtiHazarD i have a desire so im not sure if this is suppose to work but all 3 methods fail for me, any advice, thanks in advance

Nice steps! man hope this gets a good stick or added to the rom bible, you do know though fastboot method is a common way to flash recovery

That's what I was thinking... Seems almost pointless for a guide since there's instructions how to fastboot on every recovery thread.
Either way, nicely written guide. Someone will probably find this useful.

With a desire this is quite different, as it has an activated nand flash protection (s-on), so no fastboot flash recovery here. Although this should prevent you from not having a recovery at all...
* note: I don't have a desire (yet) so this is speculation *
Best is probably something similar to this http://forum.xda-developers.com/showthread.php?t=750852
I guess if you get the correct PB99IMG.zip for exactly your device/brand you will not need a goldcard, so don't follow the howto blindly (it is for the newer SLCD versions, but the basics will still be applicable to AMOLED devices). Best would be a PB99IMG.zip that still has a hboot version < 0.92, otherwise you will need to downgrade to root. If you already have 0.92, then just take the newest image, as older ones are normally not flashable.
After step 7 of the howto, you are either done, or you will need to find instructions to downgrade if you want to root.
As soon as you have a working system, with a 0.8* hboot you can just use unrevoked to root and flash a custom recovery.
Enough OT... @ANtiHazarD: Very useful overview. Thanks.

I get into fastboot with thre android logos on skates,
even tried to restore nandroid using fastboot but I get the same error? could you help me out?
I have HTC DREAM with 1.33.0013d and radio 2.22.27.08
I am really frustrated,
I tried all you gave up here but none worked for me.

Also when I try to get into recovery I see a G1 logo with a fastboot usb written on top left in red.

Did you read everything before you flashed the 1.33.0013d SPL?
If yes, you would have noticed, that this SPL is not able to flash a recovery or radio using fastboot. You have to flash the orange-...nbh file to get back a full engineering SPL, but you will loose everything you have installed on the phone ...

i don't know about this spl, but all what you can do (what i know) you can use this method which named in prev. post. with RC29 or RC7 stock firmware *.nbh
after flashing all data, radio, recovery will be reflashed by a stock data. All must be fine after this... i hope

Don't use RC29.. its once of the most annoying NBH files to need to re-root for the dream.
If you have 1.33.0013d note the orange.nbh posted on the new radio OP post: here

If you find yourself stuck without recovery!!

1) Download: orange-1.58.73.2.nbh (MD5: aca4dee0c1ece7e9773f2ecbdfbba7c0) (mirror)
2) enter fastboot and run 'fastboot flash nbh orange-1.58.73.2.nbh'
3) wait for the entire nbh to flash
4) boot into the bootloader again (it will be an engineering SPL 1.42.2000)
5) You can now re-flash the radio/hboot/recovery via fastboot that you wish to have installed.

basically if you intend to still use the new radio; after installing 1.58.73.2 you can reboot-bootloader; and use my fastboot installation steps at the top of that post
You can do this without a goldcard because I bypass various checks in 1.33.0013d
(It will let you install any other signed NBH but that will still wipe the phone completely; and if it fails to flash cleanly it will leave you without an engineering SPL thus make it harder to make android go again)

hey i tried to flash the MTD too and now i keep getting "E:cant open CACHE:recovery/log" when i go into recovery . I can flash roms but when i reboot my phone my phone stays in the G1 Logo . and when it does make it to the rom i can not get my market or gapps no matter what i do . please help me guys .
EDIT: theres times when i get past the g1 logo but itll just stay on the roms boot screen forever until the phone dies . does anyone have any ideas ?

Really, especially when using the 14MB-hack or CustomMTD and it's not so difficult. There should be a tutorial on adb and fastboot here in the forum.

[Q] MT3G bad recovery flash, stuck

Hi,
I have a mt3g, TMobile. CyanogenMod 6.1.0, ClockWork recovery. Used ROM Managed to flash Amon Ra recovery, since I needed to re-calibrate the battery. It asked me to pick phone model, picked Ion/MyTouch 3G. After reboot:
- Stuck on splash screen if I try to go to recovery
- When booted up - a bunch of force closures, keeps playing a ringtone over and over and...
Everything I tried to do through ROM Manager didn't help.
Any help is appreciated.
Thanks.

Do you still have root? If you can get into ROM manager, reflash clockwork recovery, then wipe cache, dalvik, and run a fix permissions. That should get you back up and running long enough to try again to flash amon ra.
Not sure if the oem spl will let you fastboot flash a new recovery but that's your most reliable bet.
It sounds like it might be time to do a full wipe and reflash anyway. Have you heard of Ohsaka's SuperWipe?

I tried reflashing Clockwork through ROM Manager. It says "root granted", "clockwork flashed" immediately. When I try to boot into recovery - I get stuck on green MyTouch screen forever. Battery pull is the only way out.
I guess the problem is that I cannot get to any recovery anymore. Any ideas?

Do you have fastboot. If so you can flash recovery from there.

Fastboot is a different mode. Boot into hboot (vol down + power I think) and then select fasboot from the menu. Then plug into computer. From a command prompt type:
fastboot flash recovery recovery.img
The recovery needs to be in your tools or platform-tools folder and named recovery.img for this to work. Otherwise it would be fastboot flash recovery c:\path\to\recoveryfilename.img. Make sense?
Link to Amon_Ra Recovery 1.7 for MT3G 32B. http://www.filefactory.com/file/caa48b0/n/recovery-RA-sapphire-v1.7.0G-cyan.img
Otherwise keep trying with ROM Manager. Might take a few attempts to get recovery to stick, even temporarily. It did for me. Flash once then flash again. There's also an option in ROM Manager settings to erase recovery prior to flashing. Check that and see if it helps.

The recovery needs to be in your tools or platform-tools folder and named recovery.img for this to work. Otherwise it would be fastboot flash recovery c:\path\to\recoveryfilename.img. Make sense?
Link to Amon_Ra Recovery 1.7 for MT3G 32B.
Otherwise keep trying with ROM Manager. Might take a few attempts to get recovery to stick, even temporarily. It did for me. Flash once then flash again. There's also an option in ROM Manager settings to erase recovery prior to flashing. Check that and see if it helps.

I appreciate your help.
When I try to flash recovery.img, I get this: error: cannot load `recovery.img`
When I try running fastboot with absolute path, I get: FAILED (remote: not allow). Is there a way to fix this?
Tried flashing through ROM Manager many times - no result.

Interesting... Where are you trying to flash recovery.img and getting that error? What method are you using? Are you sure you have the path to recovery.img correct?
As for fastboot, you need an S-OFF/engineering spl so I guess that's out.
What happens if you use Terminal Emulator?
su
flash_image recovery sdcard/recovery.img
Does that work? Keep at it, you have root so not all is lost. Eventually you will get there.
EDIT - make sure you rename the recovery to "recovery.img" and leave it on the root of your sdcard for my italicized instructions above to work. What ROM are you running? If flash_image doesn't work I need to know which version of the binary to give you.

Thank you very much.
Running flash_image recovery command using adb shell a few times did the trick. I was able to boot to Amon RA recovery, wipe and flash CyanogenMod 6.1.0.

Nice! Glad you got it sorted out.

Can't downgrade MT4G?

Hi all, I am going to be as thorough as I can. I am rather new, and I'm stuck trying to downgrade my MT4G to froyo (PD15IMG). I have read the tutorials, and learned enough about adb to attempt this task, but I think by doing the HTC Bootloader unlocking update last week, it may be the reason I'm stuck. I follow the instructions on the tutorial, to gain temp root, until I get to the part where I should get a "#" in the command Window when I type "adb shell" but I keep getting "$" instead, although everything seems to be going ok until I get to that point.
*Also, I put the PD15IMG.zip on the root of my sd card, and start my phone in bootloader mode, and it finds the PD15IMG.zip, and a blue progress bar appears in the top right corner of my phone for about 90 seconds, it then displays "parsing PD15IMG.zip" then stops at the hboot screen and does nothing. I just select power down, then power on my phone and nothing will have been done to my phone. I guess what I need to know is, by doing the HTC bootloader unlock update (which I did before I read that it was a bad idea), can I still downgrade and root with normal methods, or will I have to do something different?

You can start differently. Since you've unlocked the bootloader, try to flash recovery directly, by downloading recovery image directly from Clockworkmod site, rebooting to FASTBOOT (adb reboot bootloader) and using the command "fastboot flash recovery your_just_downloaded_recovery.img".
If recovery flash doesn't work for you - download the 2.2.1 PD15IMG, unzip it, and flash the following 2 files from it:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot erase userdata
Then reboot. You should end up on 2.2.1, which is perm-rootable using the guide (Visionary for temp-root, gfree for S-OFF, and then perm-root if you want).
Then flash the recovery and the engineering bootloader.

Here is what I did, I am giving a link to pastebin as instructed, it seems to go perfectly until I try to flash the StockRom. In the meantime I will attempt what was just posted above^^^^^^^ http://pastebin.com/fYrC6tAZ

One last thing before i have to throw away my phone. I couldnt leave well enough alone. I did this "fastboot flash boot boot.img" as you stated in the post above. It was successful. I then entered this one "fastboot flash system system.img", and it failed (said the img was too big or something) so I did the "fastboot-windows reboot" command and it is now stuck on the white HTC MyTouch 4g splashscreen. Is my phone toast? My PC no longer recognizes that my phone is connected to the USB port, however I can hold the volume dwn & power button and it comes on in the hboot mode.Is there any hope?
Also, when I boot it up by vol/dwn & pwr, the Hboot screen comes up and finds the PD15IMG that is on my sd card, goes through a 1 minute or so process (a blue status bar loads in top right corner), then it just stays on the hboot. It did that before it stuck on the splash screen, but never actually wrote anything i dont beleive.
OK its letting me use FASTBOOT and here is exactly what I got when i tried to flash the 2nd file in your post above. It came from the PD15IMG.zip as you instructed:
C:\adb>fastboot flash system system.img
sending 'system' (571388 KB)... FAILED (remote: data length is too large)
finished. total time: 0.016s

Can someone please let me know if there is hope for my phone? I can communicate with it through Fastboot (on my PC) and it will boot up in hboot mode. But it WON'T go past the Tmobile/MyTouch splash screen. If I get it fixed, I promise to never touch it again until I study! I truly feel there is hope, but I think don't know enough to figure it out. I loaded the PD15IMG on my SD, and it attempts to flash it, (a blue status bar appears in top right corner and fills up in about 90 seconds), but afterwards, it still sticks on splashscreen. Is there anything I can do to fix it? Anything I can flash it with in Fastboot? Please anyone?

You mixed 2 ways, and did it completely wrong way. And you didn't attempt to flash the recovery at all.
The first part, that went well (till ./flashgc), already prepared your phone for downgrading, and you should have recognized and understood it. You don't need anything else, no flashes from bootloader or anything. All you needed was to continue - put PD15IMG.ZIP on the SD card, reboot into bootloader, and let it downgrade.
You can still do it, so please do.

Once you end up on 2.2.1, please follow the "Ultimate rooting guide" from Development section, and flash Engineering bootloader.

Thank for your response. I have tried doing the PD15IMG.zip by booting my phone in bootloader mode. It finds the PD15IMG.zip and then a blue progress bar appears in the top right corner of the phone, finishes in about 90 seconds, the a message appears that says "wrong zip file". I would be happy just to get my phone back on with the gingerbread 2.3.4 on it, and simply leave it alone until I know what Im doing. Is there a way to just flash the original s/w back on it? If so if you could tell me how I will not mess with it again until I study alot more. But flashing the PD15IMG doesnt appear to be working for me.

Download the file again, and check MD5SUM on it before you use it.
If it responds "wrong ZIP" - it's because the ZIP is corrupted. When you'll download a good ZIP, it'll work.

Ok you were right, the one I had the wrong MD5SUM, but i d/l the correct one, it had the correct MD5SUM, but it still gave me the "wrong zip file error". I feel like there is hope, but I cant figure this out!! Thank you for trying, is there anything else I can do? I also tried going into recovery and doing factory reset/ data wipe etc...but it continues to get stuck on the splash screen....

How did you copy the correct one to the phone's SD card, and where did you put it? You either didn't copy it to your SD card, or named it wrong, or put it in wrong location, not overwriting the older file.
In any case, if flashing PD15IMG fails for you:
Download CWM recovery from here:
http://download.clockworkmod.com/recoveries/recovery-clockwork-5.0.2.0-glacier.img
Boot to bootloader.
Enter FASTBOOT.
Execute:
fastboot flash recovery recovery-clockwork-5.0.2.0-glacier.img
Boot to recovery. You should have Clockworkmod.
Download a stock rooted 2.2.1 ROM from Development section.
Flash it in Clockworkmod recovery.
Extract boot.img from this ROM.
Flash it in fastboot, using "fastboot flash boot boot.img".
Boot into the ROM.
Proceed with gfree.

OK!! I got it fixed and it all makes sense to me now! I flashed the 2.2.1 boot.img to my phone, when it still had the 2.3.4 on it. It was as simple as that. I hadnt flashed the downgrade on it when I flashed the boot.img and I guess it was a mismatch. I read your last post to extract the "boot.img" from the rom and then it clicked! Yesterday I wrote the 2.2.1 boot img. to a phone that had 2.3.4...so I found a stock 2.3.4 rom, extracted the boot.img from it a BAM! its rolling again....thank you so much....

Yes, indeed, you flashed a mismatched, older kernel to your ROM. I was suggesting that you install custom recovery and change the ROM to match your boot.img, but the other way around also works - as long as you don't need to root your phone, that is.

Well I will soon attempt it again, however I think I need to read a little more so I can understand the concept of what I am doing. I learned a ton by making that mistake. But as soo as I got it fixed, I couldnt resist, I used revovery and flashed [ROM]:: ProjectMIUI 2.2.17 [R6]- UPDATED 2/21/12 - [Stable + Smooth from the DEV section and I have never been happier with my phones performance! I will soon try the cyanmod, but I want to chill with this rom for a week or so. Again, I appreciate your help, I learned alot.

As long as you don't mind flashing kernels separately using fastboot for each ROM you flash, you can go indefinitely and flash ROMs as much as you like with your current setup, not needing anything else. The only good reason for you to go for S-OFF would be to flash Engineering HBOOT, to be able to flash kernels from recovery directly, avoiding extra fastboot step.
Also, thanks for finally confirming that you can flash recovery using fastboot on HTC-Dev-unlocked device. There was one device that didn't allow it (I think Incredible S, but not sure), so it's good to know that on MT4G it works as it should.
