Are you fully rooted with s-off?
What steps did you take to install it?
What errors showed, if any?

i have s-on but unlocked it with htc's unlock bootloader. how do i get s-off?

You can't get s-off yet with that method, we still need to figure it out.
To flash a kernel, pull the boot.img from the zip you want to flash, and use fastboot mode and 'fastboot flash boot boot.img' to flash the kernel.

hey nipqer,
hey guys,
I'm a noob and whatI wanted to do is having root,
i've succeeded with the htc official boot unlocker (didn't knew it was that crappy)
and using supertool (with zergrush exploit method)
now that i'm less of a noob , I 've found out that I don't have s-off
so you are 100% positive when you're saying it's not possible to have it?
is it the reason why when I want to save my current rom in rom manager it shows me a red !
and tells me: “e:can't open /cache/recovery/command”?
I want to install a new kernel for overclocking, do you confirm that what you are saying is the only method for my situation?
"to flash a kernel, pull the boot.img from the zip you want to flash, and use fastboot mode and 'fastboot flash boot boot.img' to flash the kernel."
thanks a lot.

The red triangle with ! is the stock recovery.
The htcdev method keeps recovery and boot locked, unless you flash it via fastboot.
So pulling a boot.img and 'fastboot flash boot boot.img' is the only way
(though I have heard of someone working on a recovery to defeat protection, no idea how its coming along though)
-Nipqer

thanks a lot for your answer, so that's why I can't save with rom manager right?
another question before I flash my boot.img, because i want to be sure and I didn't found a clear answer yet..
can I get a boot.img extracted from any rom for Desire z ,i'm thinking about a virtuous unity for exemple...
will that work or do I have to get a special kernel?
do I risk a brick flashing that way?
thanks

Yeah that's why rom manager won't flash a recovery.
I really advise you to use the kernel that came with the rom.
Though most aosp kernels will work with other aosp roms, and same with sense (doubt sense 2 will work with sense 3.x and such like)
Also, you may have to replace certain files in the rom for everything to work (wifi, camera, etc)
There is no brick risk
-Nipqer

ok thanks
so you advice that I dont flash the kernel at all?
what I understand is that it's way too different from the original Rom, right?
I've got a couple more questions for you if you don't mind
what if it's from a ROM that's close to sense, like the VIRTUOUS SENSE ?
and is it possible to save my kernel as a backup or not ?
it's really a pain in the ass as I only want to overclock my DZ a bit...
And I really hope someone finds a solution for that S-ON problem with the official HTC unlocker...
thanks a lot again!

Well instead of flashing just a new kernel and staying on stock rom, I'd say change the whole rom.
Virtuous Sense is just an optimized stock rom, it is real nice if you want to stay as close to stock as possible.
Though the kernel should work, if you don't want to change rom.
As for backing up your kernel, you should be able to backup boot in recovery. It's just reflashing it which is a bit of an issue.
I'm pretty sure the next version of 4ext recovery will have a feature to allow boot.img to be flashed from recovery.
how do you mean, s-on problem? If you want to get s-off you can relock your bootloader, downgrade and run gfree
-Nipqer

ok then ,I have to agree on a whole new rom as well as it makes a lot more sense.
thing is ,for some reason I'd like to backup and be able to restore my original kernel, I like the idea of coming back to stock, so I guess I will wait for 4ext.
stupid question: is it possible to have several recoveries?
I mean I already have clockworkmod recovery.
I'm talking about the lack of S-OFF for the HTC official method (it was easy but it sucks) maybe I will find some time to apply the XDA method some day...downgrades kept me from doing it(yeah I know ,I'm not the same to feel that stupid
thanks

When you downgrade its only to exploit a loophole to let you permenently root your phone. Once rooted you will then be able to upgrade to many roms, all of which will be an upgrade. As for two recoveries not at the same time but you can always change to 4ext or what have you
Sent from my HTC Vision using xda premium

ok thanks for the reply...
for the recovery,it seems that with the 4ext updater tool even if I install a recovery from there, it's still clockworkmod...there is also 2 versions with newer recoveries for the pro one??
gonna flash it manually...

well ,I just flashed the boot.img alone form virtuous sense,It's nice because I have overclocking now
what isn't that nice is that it seems that the Wifi doesn't work any more...any idea?

A full wipe and reflash may cure your wifi problem
Sent from my HTC Vision using xda premium

thanks a lot,thing is I flashed the kernel only,so i guess it only works with a full rom install
I would have loved to find a kernel that's close to sense 2.1 with overclock...

The kernel may not fully be compatible with your rom, maybe try a similar custom rom with the kernel supported by the dev or try a diffrent kernel to flash over existing rom
Sent from my HTC Vision using xda premium

Sorry about the little bit of offtopic, but I think it will be alright if I ask it here...
So, how do you flash kernel? Is it just a .zip file that can be flashed from recovery (I have S-OFF)? And will that erase all my apps and data if I already use custom ROM?

flashing custom rom-hboot 1.36

quick question: i updated my phone through the official jb update,so my hboot is now 1.36.
phone is unlocked and rooted also cmr custom recovery.
do i have to flash the custom 1.36 firmware or is the ota update one ok to install a custom rom.
reason being,just been in bootloop for an hour or so after flashing custom rom,but it could of been a bad flash on a corrupt boot.img,solved with several fastboot erase cache's and lots of re-boots
just want to check that the ota 1.36 is ok to flash a custom rom with.
thanks in advance,merry xmas.

Yeah, no difference.
Which ROM did you flash and is the standard boot.img compatible with the "JB hboot"?

insertcoin,i did extract the boot.img and flashed first-must of been a bad download,did not check the md5.
although i used the tool flasher for the boot.img,think i'll stick to cmd.
thanks for your input....

same problem
Well, appearantly you're not the only one... I tried to flash CM10 today, but didn't work either... Also got stuck in reboot. I hope someone can explain what i'm doing wrong.

You need to flash modified boot.img on newer hboots, and you would be aware of this if you read the OP carefully. Post 9308 in CM10 thread.

as far as i know htc havent released the one x jb kernel source yet (though the one x+ has i believe) so any non stock roms/kernels ie cm pa aokp ect are missing features = bt,gprs,ect. im not sure if there is a aosp rom/kernel that is fully working for hboot 1.36 as ive read through lots of threads and as to be expected there is a lot of conflicting information.
if any one can clear this up for me it would be appreciated
is there a non stock rom that can be run on hboot 1.36
sense based roms can be flashed on hboot 1.3.6

See my sig. It runs on all hboots.

I found the thread for that ROM but the links are no longer available.
I cannot find another ROM that is able to boot on 1.36.

What rom are you after. All roms run on your hboot !
Does the top of your bootloader say :
Endeavouru ?
If so check here in the android dev & original android dev section for a rom......there are plenty

Q about boot img

Hi was wondering if somebody can help me. I am new to htc devices and am learning loads about how a phone operates ect due to no s off but was wondering.
if I was on htc custom jb rom ie insercoin but wanted to flash another stock based rom ie miui australia or any other stock based do I have to flash the boot image as I assume there using the same kernel. Is this correct and can it be done. Im probaly miles off. Also can a boot image be flashed through terminal emulator on phone
Im prepared to read but couldn't find a explanation so a link would also be appreciated
sent from my highgrade HTC one x

You always have to flash the boot.img from the rom you are about to flash ! Even if its the same, just to avoid any problems !
You can't flash a boot.img inside a running OS. This has to be done with the phone in fastboot usb mode and fastboot commands from pc (cmd prompt)
Hope this helps a bit
Edit : this has some info about flashing ....

The boot.img contains both kernel and ramdisk
The kernel might not change that much between releases but the ramdisk certainly does
You would likely find that if you don't flash the boot.img then you will just get boot loops
And to your second point. Due to the security on newer HTC phones. You cannot flash a boot.img anyway other than in fastboot.
With s-off you could but as of this moment there is no way of achieving s-off
With s-off the boot.img would automatically be flashed when you install the rom in recovery

Thanks. So when you repack a boot image are you using kernel and rom specific ramdisk
sent from my highgrade HTC one x

Yes.
Repacking is merging a new kernel with the ROMs ramdisk

[Q] Correct Boot.img For HBoot 1.39?

First off, sorry for posting here, I'd like to post in the actual rom thread but I don't have 10 posts yet.
I've installed the avatar rom, its getting to the custom splash screen and then freezing.
This is normally a boot.img problem.
The thing is just I've updated my HBoot to 1.39 and I don't know what boot.img files are compatible.
I've flashed several boot.img files from various roms I've used before, but none seem to be working.
The last comment in the avatar thread is this :
If you're on the new hboot you need a special boot.img that is everywhere on the forums.

Does anybody have any idea where I can find this boot.img that is everywhere on the forums?
Because I can't find it....

You just flash the boot image from within the Rom zip file?
I do that with every other Rom I've tried. I have no idea if/why that Rom requires a special boot.img.

Because some ROMs are incompatible with newer hboots.
@OP
See attachment. I am assuming that a modded boot for CM10 does the trick since Avatar is heavily based on CyanogenMod. Let me know if it works.
You must always use the boot.img supplied in ROM.zip. If you flash ROM A and then use boot.img from ROM B, it ain't going to work.
At the moment you need a special boot.img with nearly all 4.1.x AOSP ROMs, with a new hboot version. With 4.2.x ROMs you don't need any tinkering just flash and go.

Thanks for the modded boot.
Yes dude.
It works.
You awesome genius bastard you.

My pleasure!
It might be worth noting that GPS is broken with this boot. No workaround yet, you need to flash an Android 4.2 ROM if you really need to use it.

Haha dude, spent 3 hours trying to get this ONTO my phone.
I think it'll stay for at least a day or two...
Thanks again.

I need help to recover
Hi,
I am new to rooting, I've unlocked my HTC One X, and have backed up the stock rom through the recovery nandroid, I've flashed the Renovate 1.1 ROM, then I've decided to go back to stock ROM, when I've done it I would be stuck on Airplane mode, and this happened when I first tried to flash the renovate without flashing the boot.img that comes with it...when I've flashed the boot.img the problem is solved...so now I need help getting the boot.img file for the backed up stock rom...any ideas where I can start from?

Does every rom (4.2) need boot.img flash

Hi,
Ive done a quick search and cannot find a straight answer, i dont own HTC one x but need to modify a friends phone. as far as im aware they have a custom 4.1 rom and CWM etc.
Do i need to flash boot.img for every rom regardless of what it says on the post? some dont mention it... just want to be sure!

If the rom uses stock kernel, then no but you may lose ram disk tweaks for that rom.

Basically, Yes. If you switch over to a different ROM you have to flash the new boot image. Sometimes the boot image is also updated with a new version of a ROM in that case you have to flash the new Boot Image too.

You can install rom without flash boot.img only if you device is S-Off.
If your are S-On, you have to flash boot.img everytime you install a new rom.
I have a Desire S-Off and i can flash which rom i want without flash boot.img.
For my Sensation XE, it's the same.
For my HOX, i have to flash everytime i change my rom.

No. No. No.
Some or most kernels and ROM's for the OneX are NOT set up to flash the boot.img in recovery precisely because there is no method to S-Off the phone. Devs have simply stopped implementing the method. I have no idea which ones can and cannot so err on the side NONE can and you cannot go wrong.
Always flash, in fastboot, the given boot.img for every ROM is the general basic rule.

If both roms are using stock kernel and on the same base and you don't mind losing the roms ram disk tweaks you really don't need to flash.
Same if you are using a custom kernel.
So long as the kernel/base match you would just need to flash the modules.

If you use Android 4.2.2 with sense 5, you only flash boot.img one time and flash any rom except Alex-V's rom. Because still now, all sense 5 rom using stock kernek
If you flash cm, you must flash boot.img every time you flash difference rom
if your device already s-off and super-cid you flash rom normal no need flash boot.img except some rom not allow flash boot.img in update-script
