[Q] Can't boot after CM9[SOLVED]

Hey XDA
I tried to install CM9 today, it fail...
I have unlocked my phone using htcdev.com.
Then I followed this:
If you unlocked your phone via htcdev.com, you must flash the included
boot.img after flashing the ROM in recovery:
- Boot into fastboot, either by:
- Turning phone on whilse holding VOLUME DOWN, or
- adb reboot bootloader, or
- using an option in your recovery (eg. Reboot Bootloader)
- Connect your phone to your PC and copy the boot.img from the ROM .zip
to the same place as fastboot.exe and issue the following command:
- fastboot flash boot boot.img
Failing to follow these instructions on a htcdev.com unlocked device will
cause the ROM to fail to boot.
And now it just stands with a mobile and a ret warning sign. I can get in bootloader, but that's all. I have the CM9.zip on the sdcard but I forgot to run it before I did the above mentioned. I have tried to reset the mobile from bootloader nothing helps
Pleas help me what should I do?

So what is your problem exactly ? Do you have a custom recovery like 4EXT ? It's needed in order to apply the CM9.zip.

None
No i have not installed any recovery app. I cant start my mobile

1.install a custom recovery like 4ext or cwm
(2. Backup current system) this time you don't have to do this since you don't have a working system at the moment.
3. Full wipe (data, system, boot, caches... Not sd card) from recovery
4. Flash ROM zip from recovery
5.flash boot.img via adb
6.reboot
7.done

I'm assuming you know how to boot into fastboot and use fastboot and adb commands. If not, just click on the link in my signature under Helpful links.
Once you're done, just put the attached file in your adb folder, then boot into fastboot and issue the command ;
fastboot flash recovery recovery.img

You will now have the custom 4EXT Recovery. From there, just follow the steps you outlined in your first post, and you should be up and running.
Cheers.
EDIT: I see you already got it working while I was composing my post. Congrats!

@op could you please update the thread title to something like [solved]

[Q] Problems with cleanROM 2.2 install..User Error

Okay, sorry for being such a noob. I am learning. I run the boot img file and it goes through the stuff and says now reboot to recovery to flash rom. Select Bootloader from menu then select Recovery. I have CWM installed. After it say that in cmd do i go to recovery and flash the zip file Boot.imgflasher? I tried that and it say initializing and then it says canceled. So I guess my question is what am I doing wrong? and how should i properly install this? THank you for you help. This is the thread http://forum.xda-developers.com/showthread.php?t=1655011:eek:

you flash the boot.img before you go to recover, that's it.
"i go to recovery and flash the zip file Boot.imgflasher?".....NO.....
you just flash the cleanrom.zip ....

Okay so from the home screen with the phone on flash the Install boot.img after that go to bootloader and wipe data. then reboot phone and that is all?

[Q] HELP Won't boot

Trying to root using easy ace root tool. All seemed fine until I tried to flash rom. Now phone will boot to HTC screen and stop there. I can get into CWM and hboot, I have copied files to the SD from there but I can't get it to boot normally. I have tried putting a new PD98IMD but am not totally sure I have the right one. I miss the AAHK

You need to fastboot flash a boot.img.

tried
I tried that with no change
Unlock your bootloader and flash a custom recovery (CWM or 4ext)
Download the rom zip file you are willing to flash to your PC.
Extract the the boot.img from inside the zip file (do not extract the whole rom)
Put the zip file in your sdcard.
Boot into recovery and do a full wipe (wipe data/factory reset, wipe cache partition, format system)
Flash rom (install zip from sdcard)
Reboot into bootloader again and plug the phone to the PC.
You need to be in fastboot usb (if you see HBOOT USB PLUG in the phone, just press power to toggle)
Open a cmd/terminal and navigate to where the boot.img file is located.
Type: fastboot flash boot boot.img
Reboot and now you should be enjoying your custom rom

And what does it say when you run fastboot flash boot boot.img?

worked

Did the flash boot from here and it work using ext4

Glad you got it working. You'll need to do the boot.img flash every time you flash a new ROM.

Just got a mini

And I'm trying to figure out the steps to rooting and installing a custom recovery so I can flash a custom Rom. Anyone have the tuts on how to do this?

This guide by Ecstacy42
1. Unlock your bootloader here. Select "All Other Supported Models" and follow the instructions.
2. Download the Rom, Kernel, and a recovery, verify the MD5 checksums, and then copy the rom and kernel zips to your internal SD card. I'd recommend one of the WWE versions as they don't have a lot of the AT&T bloat.
3. Boot into the bootloader (it says how in the guide showing you how to unlock your bootloader)
4. Select fastboot, plug your phone into your computer.
5. Type "fastboot devices" to make sure it's connected, then type "fastboot flash recovery whateverrecoveryyouused.img".
6. Boot into recovery. Make a backup. Then wipe system, data, cache, and dalvik cache.
7. Reboot into fastboot, then type "fastboot flash boot boot.img" using the boot.img from the Rom you downloaded.
8. Reboot into recovery and install the rom zip using TWRP/ClockworkMod.
9. Reboot into fastboot and type "fastboot flash boot boot.img" using the boot.img from the kernel.
10. Reboot into recovery and flash the kernal zip.
11. Start up your phone, if you flashed a DeOdexed Rom it'll take a little while to boot up.

Accidentally delete everything using TWRP in "wipe"

Hey,
first of all i KNOW there is a subject with nearly the exact same topic, and i followed the directions but somethng doesn't work.
I still have TWRP on the phone, and when im in bootloader mode and run "fastboot devices" i see the result.
but i can't seem to ADB push or anything else (maybe im missing some commands?)
so i used the NRT root kit and i use the "fastboot flash" function and install the .img file - the software says my device is identified and it installs the system.img file (found on the "image-hammerhead-mra58k" zip), but then the device boots to TWRP and still can't boot to the system itself.
help please!

Sideload a factory rom and u will be fine. U can do it in the advanced portion of TWRP, but u need a pc, or ur hit

Sounds to me like you're using adb commands in fastboot.
Boot into bootloader (not recovery)
Type fastboot devices
It should return showing your device
Then you need to make sure you have stock img's downloaded and completely extracted so you have all the img files in the folder you're running fastboot from (rename the radio to simply radio.img)
Then type
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash radio radio.img
Then boot back into recovery and wipe cache and dvalik for just in case fun
Then reboot system and wait
