[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

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.

First off, I'd use TWRP since it's compatible with all ROMs and CWM has very little compatibility with our phone.
To do that, download TWRP 2.3.3.1 Check MD5
boot to bootloader/fastboot
then fastboot flash recovery twrpfilename.zip
then wipe cache, dalvik, system, factory reset in TWRP
Flash rom.
If you are on hboot 1.14, you then need to extrract the boot.img from the ROM's zip and fastboot flash boot boot.img
As for the not able to mount SDCard, did you factory reset in the bootloader?

Hey my friend thnks for the reply. I'll try all of these right now. If u can please follow the thread, I might have more questions...Thnks again!

I've reache the point where i mount again my sd card and making all thw wipe things...
I' ve installed the rom but after it says that is succesfully installed and rebooting it shows the htc logo and after that...nothing!
The device turns off(or at least i think it is)black screen, no charge little orange light...But when it comes to this mode, I can hear the soun of the pc like when u do connect a device!
What am I doing wrong?
And yes I have hboot 1.14. What is the correct sequence in the actions????

Did you extract the boot.img from the rom and then flash it using fastboot?

[Q] AT&T HTC One X Bricked and need advice

Hi,
I have an AT&T HTC One X with no OS. I wiped it when I was trying to flash a custom ROM.
I only have access to bootloader and TWRP. Fastboot is working fine but TWRP is not. It does
mount properly, and adb sideload fails as well. I am using a Windows 7 PC and used a USB 2.0 port.
I installed some HTC Drivers from here:
http://forum.xda-developers.com/showthread.php?t=2217396
but it still says "device drivers failed to install" when I boot into recovery.
When I try to mount, it does not let me mount the sdcard. I see an E: drive on my
PC but it is inaccessible.
I have S-On, my bootloader is unlocked, and I have hboot version 2.14 if that info helps.
Does anybody have any suggestions as to what I can try next?

First thing you need to do is clear your post up a bit. You said you have access to TWRP but it isn't working, can you elaborate on that please?
You also said that it does mount, but then you said later it doesn't mount, which is it?
Have you performed a factory reset from the bootloader at any point?
Exactly which ROM(s) did you try to install? I need the exact filename(s) please.
Did you remember to flash the boot.img with fastboot after flashing the ROM?
Do you have a TWRP backup on your phone?
Please answer all questions with as much relevant detail as possible, that'll aid me to help you properly.

I helped him over teamviewer so I can clarify the situation. He can't mount in TWRP, it must of been a typo. It seems he cleared everything when he was trying to wipe to flash a rom. I believe it was ViperXL. He has no backup and sideload does not work as well. Hopefully that will clear things up a little bit more. I installed some newer HTC Drivers since the ones he had were old. The only thing that works seems to be fastboot at this point.

Sorry it was a Typo, I was not able to mount at all. The error said "unable to mount /sdcard"
Yes I have tried performing a factory reset from bootloader but the phone restarts and comes back to TWRP and then same thing.
I tried installing the ViperXL ROM but was not successful.
I was not able to flash the ROM and I tried to fix that but meanwhile looks like I wiped all what I had on my Phone, so no but I did try to flash a new boot.img after and it didnt work.
I dont think I have any TWRP backup on my phone, even though I tried flashing new TWRP but all failed.

Ok first thing, don't ever perform a factory reset from the bootloader because it corrupts your sd card. That's why you're experiencing problems now. You need to wipe the sd card/internal storage using TWRP 2.6 to make it usable again. If you don't currently have TWRP 2.6 installed you'll need to do that. Download it from here. Put the file in your fastboot folder. Connect phone in fastboot mode, open command prompt from within fastboot folder, issue the following commands:
Code:
fastboot flash recovery "filename.img"
(the exact filename, minus the talking marks)
Code:
fastboot erase cache
Code:
fastboot reboot-bootloader
Now you should be able to mount your sd card using TWRP and copy a ROM across to flash.

I rebooted into recovery, still came up as TWRP 2.6.3.0, then I went to TWRP reboot and chose Recovery, phone rebooted into TWRP 2.6.0.0
Tried mounting (could not select /sd card and /cache(expected as we erased it)) and ADB sideload, got the same errors as before. Unable to mount /sdcard.
Rebooted again and it displayed TWRP 2.6.3.0

Did you wipe the sd card/internal storage like I said before trying to mount it?

Its 2.6.3.0, but in recovery when I go into option TWRP reboot and chose Recovery button, phone reboots into TWRP 2.6.0.0 and when I reboot it again, its 2.6.3.0

That's really screwy. I think you should try installing recovery again. What happens when you boot the phone normally?

Ok good news, something happened, I tried all the steps again carefully and now I see TWRP 2.6.0.0 on boot and I am able to mount the sdcard and my computer now recognises the phone and I can manually copy files on to it.
Now in order to not mess it up anymore, should I just copy ViperXL ROM or should I use ADB sideload?

Either one should be fine. If you have S-ON and the phone gets stuck on the HTC screen, you have to flash the boot.img. here's how to do it.
1. On your PC in the ViperXL.zip, take out the boot.img and put it in the directory where you have the adb and fastboot files.
2. Boot into fastboot.
3.Open cmd. Change the directory to the folder where you have those files.
4.type "fastboot flash boot boot.img"
5. Reboot the phone.
The phone should boot.

Definitely install through TWRP. You shouldn't need to flash a boot.img because Viper uses an aroma installer which does that for you. But, if for some reason it doesn't work just flash the boot.img via fastboot.

So I flashed the boot image, then copied ViperXL and installed it through TWRP, it failed.

Exactly which error is it giving you? Did you check the md5 of the downloaded file? Are you still on TWRP 2.6?

No I did not check the MD5, yes I'm on TWRP 2.6.0.0 and the errors it gives are as follows:
unable to mount '/cache'
unable to open zip
Error flashing zip

Always check the md5. It's possibly corrupt.

Yup redownloaded the file, checked/compared MD5, copied it back to the phone, removed the previous bad copy, flashed ROM successfully..., as per the message but system reboots to recovery.. is that expected?
And I still see both the TWRP's 2.6.3.0 and 2.6.0.0 the phone needs couple reboots in order to get to TWRP 2.6.0.0 but automatic reboot is in TWRP 2.6.3.0 whats the deal here?

I have no idea why your recovery is acting like that. Hopefully someone else can chime in on that.

I was having the same issue, what I did to fix this was:
Put the TWRP flashable zip onto your phone
Plugin your phone to your computer and used the fastboot command "fastboot boot recovery.img"
Leave phone plugged into computer
From there flash the recovery zip, unplug, and reboot to recovery

Hi
Thanks for using XDA Assist.
You cannot flash zip files through fastboot. You need to download a twrp image and flash it individually with;
fastboot flash recovery <name of image>
Make sure the image file is in the same directory as your adb window.

Thanks
