[Q] Phone can't boot after kernel flash

Hello,
So I have a rooted HTC Desire S with Hboot 2.00.0002, unlocked bootloader and 4ext touch recovery. After a couple of failed attempts of flashing the MIUI rom and nandroid restoring it, I lost the ability to connect to 3G after the fourth attempt. So, I tried to flash a new kernel on it to see if it would solve anything. It didn't, whenever I boot up my phone it hangs on the HTC logo, then reboots a little while in 4ext recovery mode.
From here I again tried to nandroid restore, but with no luck.
How do I get my phone back to working? (what I had before was rooted stock rom)
I have tried these two kernels: http://bit.ly/ozxbWr (HTC-Kernel-2.6.35.10) and the Reaper 3.0 kernel (http://forum.xda-developers.com/showthread.php?t=1433816).
Thanks.

Alright, found the problem. For future Googlers here is how I fixed it.
So, first I downloaded a custom rom for my phone, MIUI. I placed the zip on my micro-SD card (I have a converter so it will fit into my laptop) and booted into 4EXT recovery. I guess you can use ClockworkMod Recorvery aswell.
In here I picked "choose from SD-card" and picked my .zip file and installed it.
After installation you boot into the bootloader (Volume Down + Power button) and go into fastboot. While in fastboot you plugin your USB-cable.
Set up ADB and Fastboot with this guide http://forum.xda-developers.com/showthread.php?t=1272595
Now go back to where you downloaded the custom rom to and extract the boot.img file to the folder where adb.exe and fastboot.exe is.
Upon up a cmd in your folder where adb.exe and fastboot.exe is in (Use Shift+Right click, pick "Open cmd here").
Now write exactly the following
Code:
fastboot flash boot boot.img
.
Press Enter and let it do it's job. When it's done you can unplug the USB cable and restart the phone as normally. The phone will now function again.

Did you unlock your phone with HTCDEV? If so then it is extremely well documented that you have to flash to kernel separately.

Help Required - Stuck and splash

Greetings.
This is a long (and sad) story, take a breath..
Me and my wife both have Sensation for over two years.
Mine is Revolutionized s-off etc for a very *VERY* long time...
Her Sensi was stock till some stock apps drove her mad and a couple of months back I got it HTC dev unlocked, with 4ext, but JB method for s-off (with the wire trick) was giving me a hard time, so I just kept it s-on and tmp rooted, killing some stock apps.
Now the mess begins.
After some complaints that it's slow and gets stuck, I wanted to add some nice kernel to the pack - Sebastian's.
Since it's s-on, I picked "SmartFlash" BUT completely forgot about USB-Debugging...
So flashing the kernel made a whole mess, and it's stuck on splash. Also fastboot-usb is impossible as the usb-debugging is off.
I know.. I know.. RUU right?
I'm on Linux - which makes running RUUs virtually impossible...
Nonetheless, I extracted the rom.zip out of an ruu_pyramid_le_ics_35_s_htc_asia_wwe_3.32.707.110_r2_radio_11.69a.3504.00u_11.23.3504.07_m2_release_254511_signed.exe I had around, renamed it PG58IMG.zip - and with all the joy put it on the root of the SDCard.
The phone's CID is HTC__044 and it matches the one in the RUU rom (asia wwe).
But.. hboot, while taking its time to figure out what that PG58IMG file contains.. does nothing at all once it process it.
Current situation - I restored my wife's backup on my phone, and gave it to her, leaving me with.. a semi-brick.
I could not find an RUU for 3.33.707.51 which was the version on the phone prior to this fiesco, if you know where to get it - please let me know..
Other than that I know this is solvable, as I am able to get into recovery and hboot, but how?
Phone details:
HBoot 1.27.0000
CID HTC__044
4ext recovery touch
Firmware 3.33.707.51
Radio 11.76A.3504.00U_11.24A.3504.31_M

Why fastboot usb is not possible? Usb debugging is not at all required for fastboot command access
Do this
Extract the boot.img of any rom which has sebastian kernel as default (elegancia rom i think?)
Then copy it to your adb/fastboot folder of your pc
Then boot your phone to bootloader (remove battery, reinsert it then hold volume down + power button)
then connect the device to your pc (as your pc is linux.. It's more easy now.. No need to fetch drivers and all)
When connection is proper the phone says fastboot usb.. If it says hoot.. Press power button once
Then this command
fastboot flash boot boot.img

Would fastboot commands would work for an s-on device?

[Q] Sensation will not load past the splash screen...

I am hoping that I can find help out there. My phone will not load past the splash screen.
Over the last few days I have been trying to install a custom rom on my phone. I thought I was on the right track and now I have flashed it but it will not go past the splash screen. I would be grateful for any advice on how to get my phone back functioning. I would even be happy to have it back stock.
So my movements over the last few days have been as follows:
1) HTC DEV unlocked the bootloader
2) Used Hasoon2000's HTC Sensation 4G all-in-one to flash CWM.
3) Then the same tool to copy Prem Root onto the SD card and installed it via CWM.
4) Then used this post here to install JB Miui - http://miuiandroid.com/community/threads/how-to-update-upgrade-miui.15424/
Then when I rebooted it is stuck on the Miui splash screen.
At every stage I felt like things worked well and now I have that sad feeling in my stomach because I have just realized how vital my phone is.
Any help would be greatly appreciated.

Did u flash boot.img after u flashed the rom? Did u full wipe before flashing the rom? Also with s-on users its recommended to use 4ext recovery and in recovery, enable smartflash.

Where can I find information about boot.img - so that is a no. I am installing 4ext now.

ok, so I have been looking at the boot.img part and I found this video: http://www.youtube.com/watch?v=5xVl2dBTnmI
I have followed it but still am not having any luck.
Still very lost.

open rom.zip and search for the boot.img
probably it is located in the kernel folder
place it in the folder where you have adb and fastboot files
now boot your device to the bootloader and connect it to pc via usb(in the hboot screen it should say fastboot usb)
in the folder where you have adb and fastboot files open a cmd window and do this command
fastboot flash boot boot.img
then
fastboot reboot
done

as suggested before it is better to have 4ext recovery
and before flashing any rom enable smartflash from it(for S-ON devices)
smartflash it does exactly what i said above

Bootloop (S-ON/No Recovery) :(

Hello,
I have a big problem with my old HTC Sensation.
I tried nearly everything out of other topics, but nothing worked....
The story: Suddenly my Sensation rebooted and from then on it is stuck in an endless bootloop.
The bad thing is, that it was stock/S-ON at this moment.
Informations about the phone:
***UNLOCKED***
Pyramid PVT Ship S-ON RL
HBOOT: 1.27.0000
Radio: 11.24A.3504.31_M
-> I am able to install RUUs (3.33), but after installation i am still in the bootloop
-> I am able to unlock/relock the bootloader
-> I can install a recovery via fastboot, but can't boot into it => bootloop
Maybe you have got a hint to bring the Sensation back to life.
Thank you!

Since your bootloader is unlocked, you can use fastboot to do stuff. Most of the HTC Sensations have a HBOOT version that causes bootloops when flashing roms because their kernel doesn't seem to install properly when flashing roms. The ROM should consist of a file inside the zip, usualy in the kernel folder or in the root of the zip that is called boot.img. That is the kernel. First of all, you need to download the tools that have the fastboot and drivers included. Then unzip all of the contents into a folder. Run and install the drivers that that have come in the folder. Then go into the fastboot and adb folder. Shift rightclick onto the empty space of the folder and click open command window here. Then boot your phone into bootloader mode. You can do this using power button and volume down while your phone is off. Once youre in fastboot mode, navigate to fastboot using up and down volume keys. Then press the power button. Plug in your phone to your computer using your HTC sync cable. Then in the adb and fastboot folder, copy your roms boot.img into the folder. Then in the command window, type 'fastboot flash boot boot.img' without the quotation marks. It should say sending and then writing. The process should take no longer than 20 seconds. Once done, restart your phone. Wolla, your rom should now be working properly!

actually he can't even boot to the recovery in order to flash any rom
so what's the point of flashing the boot.img manually?

You can use Sensation all in one kit v3 to unlock boot loader, read this thread for more detail
http://forum.xda-developers.com/showthread.php?t=1497404
after unlocking boot loader, then go to this thread to download 4EXT recovery then use kit to flash recovery, remember to download image file, not zip file

boot to recovery, then enable smart flash and flash any cook ROM you want. Remenber to wipe everything after having enable smart flash then flash cook ROM
good luck

actually first has to wipe and then enable smartflash

Thank you for your ideas!
But unfortunattly i tried most of the things.
@ kevinspl2000
I think normaly the RUU would also install the Boot Image.
But I also tried to manualy flash the boot.img out of the RUU via fastboot, but no success.
I am not able to flash a Custom ROM, because of no Recovery...
@stripeqn
The point is that I am not able to boot to Recovery...
I can flash the Recovery via fastboot, but I am not able to boot into it.
I tried different versions of CWMR and 4EXT but no success...
When I click on recovery, it just shows the HTC Logo and bootloop again

I think I have a solution. When I installed my custom recovery at first, I also got bootloops when trying to go into the recovery. What I did, is I refalshed the recovery, and then did fastboot erase cache. It wipes all of the cache, and fixed my bootloop before. Try that and see how we get on...

Can't access recovery

A friend has given me his Desire S to fix what I originally thought was just a stuck power button that prevented it from starting up. But the button is now fixes and I've been trying the last few days to get it to start up.
What I have tried so far is to enter Recovery mode, but upon choosing it, the phone would just go to the HTC logo screen, fibrate once and then fibrate agian after a second or two for a few times and the screen would go blank. The same happens with normal bootup. It also seems that the phone is still running with the blank screen because I have to pull the battery to startup again.
I then tried to use the latest RUU (Android 4.0) from HTC but the phone is not recognized by the computer (I think it is because it didn't startup enough to be able to present itself to the computer). So I unlocked it and used fastboot (from Ubuntu as OS) to flash the recovery (recovery_signed.img) and boot (boot_signed.img) from the RUU. With this recovery and normal startup would remain at the HTC screen and wouldn't go blank as before - still fibrates a few times.
I also tried to rename the rom.zip to PG88IMG.zip and putting it on a SD and the bootloader does detect it, but presents the normal boot screen afterwards (I think it complains about it being incorrect - the display is too quick for me to see the error).
Now I also have a Desire S and made a backup of it before I installed a custom ROM. So I also tried the recovery.img that I have from this backup, but then recovery is stuck on the blank screen again.
Is there anything that I did wrong, missed or may not have tried yet? And how can I go about to fix it?

The PG88IMG wont work coz ur s-on. Ul need to extract the zip file and put the recovery.img in ur fastboot folder and then flash it from fastboot, volume down + power then select select fastboot then plug ur phone into pc and open a fastboot command window and type
fastboot flash recovery recovery.img
Also a ruu u run from fastboot and u need to relock ur bootloader.
(i dunno how all this is done using ubuntu but thats how on windows so im sure ul know or figure it out)

Ok, didn't know that I needed S-OFF for PG88IMG - thanks for pointing that out . I did flash the recovery (paragraph 3), it is just named `recovery_signed.img` and not 'recovery.img` - I assume that there isn't a difference between the two?
Do I open the RUU while in fastboot on the phone (after relocking) or do I run it from a fastboot command?
(On Ubuntu fastboot is installed as a program so I can call it after I CD to the extracted rom folder and I assume it is working since I didn't get any errors)

Well it depends, could be 4ext recovery, CWM, or TWRP. But as far as the name, could be called peterpan.img and it wouldnt matter haha

Yh boot ur phone into fastboot, connect it to pc, relock bootloader and then run ruu. The ruu should be exe file so just double click it to run.

Ok, relocked it and went into fastboot mode and then opened the RUU, but was not recognized. Then followed this (droid-now.com/2013/10/fix-working-fastboot-drivers-windows-8-1-x64/) since I used Win 8.1 for the RUU and it flashed successfully.
But it is still stuck on the HTC screen - gave it 30 minutes for the first boot after flash. Recovery is also still stuck, so I reflashed and same issue.
