[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]

"Fastboot flash boot boot.img" make sure u type boot twice.
Do factory reset/wipe data and wipe cache. Flash rom. Reboot into bootloader. Fastboot flash boot boot.img. reboot phone. Then reboot back into recovery to flash gapps. Should work "

so did you already flash the (right) boot.img via fastboot?

If you haven't, extract the boot.img file from the .zip and place it where you have adb/fastboot (Android SDK). Then boot into bootloader, go into Fastboot, plug phone in for "Fastboot USB" then type the following in command prompt and reboot.
fastboot flash boot boot.img

ive tried all that boot.img from zip even another one with the download no luck just stuck on boot with that cm9 rom on loop thanks for your help though guys any other suggestions other then just shooting myself in the head??lol

Try flashing Paranoid/AOKP and then flashing back to CM9.

flash older cm9 rom?
this is my first attempt of any ROM for this phone starting with cm9 alpha 13 does anyone recomend maybe installing a older alpha?? maybe alpha 10 cm9?? idk

Try flashing the latest alpha 14. Maybe you got a bad download of alpha 13.

did you solve your problem?
if not & you're not quite shure about flashing the boot.img properly with fastboot I set up a Tutorial yesterday:
[Tutorial] How to flash a new boot.img via Fastboot
perhaps this might help you if the above one didn't fix your problems:
http://forum.xda-developers.com/showthread.php?t=1667929

I had the same problem. But this worked for me.
wipe all -> flash cm9 14 -> wipe all -> flash gapps -> wipe all -> fastboot flash boot boot.img ( i used the touchfix one ).
then i got in.. but took some time first load. But now i cant get wifi to work and cant see simcontacts. Drives me nuts.
Just reflashed all with no luck.

I can't flash a custom rom

I am using TWRP recovery, and I have tried flashing Miui and Cyanogen mod, however for both of them I am stuck at the boot logo for ever.
I factory reset the phone, wiped the cache and did everything I was supposed to do. For both of them this is the first boot, and it is not working.

Try flashing your boot.img

I'm thinking you have hboot ver 1.14.
Flash your boot.img.
Steps:
download rom
extract boot.img
place boot.img in fastboot folder
place rom .zip on sd card
clean flash the .zip
boot to fastboot
connect to pc
type "fastboot flash boot boot.img"
/dance

Before deciding to flash anything, you really need to watch this informative video: http://www.youtube.com/watch?hl=en&...ture=player_embedded&v=wwleOote5M0&nomobile=1

Can't flash a rom.. stuck on blackscreen

Hi ! I tried to flash Jelly Bean rom on my (SFR french operator) HTC One XL, but all roms won't boot.. stuck on blackscreen
I tried these roms:

- http://forum.xda-developers.com/showthread.php?t=2055490 (i hear start sound loop with deodexed rom)
- http://forum.xda-developers.com/showthread.php?t=2055877
I rooted the phone with Hasoon2000 all in one toolkit, installed TWRP 2.3.3.0 Recovery, and Wipe Factory, Cache, Dalvik Cache (i tried wiping system and Android Secure too) before flashing rom

Have a copy of rom on phone and on desktop
1. Extract rom onto desktop.
2. Copy boot.img and drop it inside of your adb/fastboot folder.
3. Enter recovery on your phone. (Twrp) wipe cache, dalvick, reset, system.
4. flash rom.
5. Boot into bootloader, choose fastboot.
6. Right click on your adb/fastboot folder and choose "open command prompt here".
6. Type--> fastboot flash boot boot.img
7. Reboot.
You "should" have adb/fastboot installed since you used the toolkit. Good luck

help !!

hello i have a big trouble with my htc one s, is a S4 variant and i try to boot normally but is always boot on the cwm 5.8! i reboot and is return to cwm! help me i try everything

Sounds like no ROM
From the sounds of it, it doesn't seem like you have a ROM installed.
A few things to remember when flashing new ROM's:
-Try not to ever flash dirty* (without wiping data, cache, dalvic cache, and system)
-ONLY wipe the system if you have another ROM loaded onto the internal SD card and ready to flash
-Make sure said ROM is COMPATIBLE with your phone. (Device model, in our case HBOOT [2.15, 2.16 have their differences]
-Try to update to the latest Recovery when flashing, unless stated otherwise in the ROM's OP. THEY WILL TELL YOU WHAT YOU NEED.
There is plenty more, but for your issue these may help.
Update your recovery through FASTBOOT and then use the MOUNT option to mount your SD card and add a new [compatible] ROM and try to flash it. (and if it has GAPPs, flash that AFTER you flash the ROM)

i dont flash anyrom, i just flash the recovery and write this command line "fastboot flash boot recovery*.img" (just a cut of the .img of the recovery) and after that, is allways reboot in recovery mode

Code:
fastboot flash boot recovery.img
flashes recovery to boot sector. That's why your device boots into recovery every time. You should use
Code:
fastboot flash recovery recovery.img
to flash recovey correctly, unzip boot.img from your rom's zip and flash it with
Code:
fastboot flash boot boot.img
to be able to boot into your rom
