Flash new kernel through TWRP? - AT&T, Rogers HTC One X, Telstra One XL

Hey guys,
Long story short, I'm running MIUI 2.11.9 and want to switch kernels to Jacobs.b3. I've never flashed kernels before, but I've done ROMS all the time. Can I just flash the boot.img file in TWRP? Do I need to clear cache or anything?
Cheers.

Yes, you flash kernels just like you flash roms except that there is no need to do a full wipe across different kernels--they fully replace each other, unlike roms. Wiping caches is still good practice though.

Thanks, that's all I needed to hear.

If you are on the 1.14 hboot, you will need to flash the kernel using fastboot. Otherwise just flash in TWRP. I always wipe cache and Dalvik whenever flashing anything. Just to be safe, and it can't hurt anything.

I don't know anything about that phone. You should post in your device specific forum section, as technical advice often differs from one device to another.
Following advice intended for another device can cause permanent damage to your phone.

I couldnt restore it, any help? I will provide more detail if asked. I just want to restore it to stock
Please someone help me ;( I just want to get back to stock.
Did you factory reset in bootloader?
Sent from my Evita
SD has been corrupted. Possibly because you did a factory reset in bootloader (known bug) as mentioned in the previous reply.
Plug the device into a Windows PC, go to device manager and format the SD. Then mount the SD in TWRP and move a ROM to the device, and flash.

Also don't forget if you are S-ON that you should flash the boot.img manually after you flash a new ROM. I use TN_WIN_Boot_Installer to ease this task.

What's hard about "fastboot flash boot boot.img" to begin with.... Using tools only adds risk
Or flashimagegui

[Q] Cannot find the resources to undo this soft brick.

I have an AT&T HTC One x. Its ***Tampered*** ***Unlocked*** HBOOT 1 .09. 0000 S-ON
I had been running an older version of TWRP, and decided I was going to clear my phone and do a fresh start. I know, I know, I should have made a backup, but I felt pretty confident in what I was doing, and was in too much of a hurry to rationalize this.
I wiped both the OS and previous version of TWRP in order to update to the new ones. While in fastboot I flashed CLEANrom and the new version of TWRP, and my administrative command prompt confirmed that they were installed successfully. Even cleared the cache afterwards. Now is the difficult part. I've researched, and researched, and cannot find a solution for this problem. I keep having a Boot Loop.... I'm stumped guys... I need some sort of help, be it technical, or something to drink lol
Previous ROM was CM 10, with TWRP and PA GAPPS :good:

It's the newest version of TWRP that is out, and yes, I flashed it via Fastboot, and it says successful on both the recovery install and ROM install.
Have you tried flashing another ROM? I asked for the exact recovery version for a reason, please provide that information.

Why are you flashing roms via fastboot? -_- You're making your life difficult. Wipe everything in TWRP then flash in TWRP. ALso, you should really s-off and update your firmware/hboot. via RUU. You will likely encounter issues running a newer software on an such an old firmware.

If you would have read the thread, you would have noticed, that I am in bootloop, therefor I cannot access the recovery. And I have to have access to the ROM on my phone in order to flash anything via TWRP so this is moot. My question isn't how to flash roms, it's why am I getting a loop when I am successful on a clean partition and clean flash of both the recovery and ROM? And to me, fastboot is way easier than TWRP. I guess I could get a UART and try to debug the sequence myself, but I have more important things to do than that. I was posting to see if anyone had any similar problems. And this phone is an original model and I haven't really bothered with the security off, since I only wanted to get rid of sense in the first place. It was unlocked well before any commercial unlocker was available for the evita(Literally no stable CM10 at all at the time), so it's a little finicky in the first place. I ran the RUU after I re-locked the bootloader, and I'm at least out of the loop. I'm just going get to a more stable version so that this process will be more streamline when I re do my unlock and stuff.
So I guess the only solution at this point I have for any problem like this is to use the proper RUU. I tried a couple of times with no success, and it seemed the charm was to re lock the bootloader ( Fastboot oem lock) in order to properly and successfully get the RUU to work.:good:
Wth are you even on about? Of course you can access recovery in a bootloop. How are you getting to fastboot without accessing the bootloader? from the bootloader you can access recovery. If recovery isn't loading SCREW flashing a rom, reflash your recovery, 2.7 TWRP preferably. and then boot to recovery, mount your USB, copy the rom and flash it. Recovery is more important than having a ROM.
I know what I am talking about, do you know what you're talking about?
FFS I am trying to help you, there's no reason for you to be an ass. You're having issues BECAUSE you're flashing your rom via fastboot. You cannot flash a rom via fastboot.

You didn't read the thread. I'm not being an ass. The information is already there.I can not access the recovery at all. That's why I am in in this situation. And again, if you had read the whole thread, or the even the original post, you would know that I cannot access the recovery. The only reason I'm being as detailed as I am is so I don't have to repeat myself, as well as for other people who may encounter this problem. And Yes I know what I am talking about. If I didn't I probably wouldn't have gotten to this point, right?

Exad is right in saying that the reason you're having problems is because you're attempting to flash ROMs with fastboot. That isn't how it's done. The correct way is to flash your ROM with recovery. You're barking up the wrong tree, not only that but you're arguing with experienced people who are only attempting to help get you out of the mess that you've gotten yourself into. You came here for advice, but there's no point in asking for advice if you're just going to argue and dismiss what you're being told to do.
You said you can't access your ROM so you can't flash anything, that makes absolutely no sense, which leads me to believe you don't really know what you're doing. Get out of the mindset that you need to use fastboot, it's wrong. You're dealing with people who have extensive and intimate knowledge of this device, trust us, we know what we're talking about.
Exactly why can't you access recovery? If you can issue fastboot commands that means you can access your bootloader, if you can access your bootloader that means you can use your volume keys to scroll through the options and the power button to select recovery. What happens when you do that? Exactly which recovery have you flashed to your device? I need to the full filename of the recovery that you've flashed.

S-on is a downright dangerous place to be, if the phone is also SuperCID (which is very likely, since its the AT&T variant). exad is right in recommending s-ff, as he is about a good many things.

[Q] reverting from custom kernel to stock?

sorry if this doesn't quite belong here but I was curious to go back just to stock kernel, not completely stock itself. Could anyone link me to a good step by step for me to do this? Do i use adbfastboot the boot.img only? Im just a a little confused..
Sorry I am still new and learning. Thanks for any help!
Download the relevant kernel to your device from here.
Reboot to recovery
Install the zip you just downloaded
This stuff tends to be a lot simpler than you'd expect, tbh.

Fastboot, you flash with fastboot and yes the kernel image is boot.img. You should probably also reflash your ROM (system.img if you're on the stock ROM) as many custom kernels also modify the system partition.

So no worries since you don't flash all (you use the "Method2" from the link I posted above), about the "flash-all.sh" file, when you open the factory image file, you have this script, more info here about the "-w" to delete: http://forum.xda-developers.com/showpost.php?p=51949577&postcount=4.

thanks for you help my brother. Just another question.. If I have a nandroidbackup on the computer that I made before I installed my custom kernel, could you somehow use that to get back to the stock kernel? Is that something...or I am just asking the most ridiculous questions?
It seems the more I read, the less I am confident with adb, flashing, backups etc.... :S

If want the stock kernel download the factory images from google and flash the boot.img via fastboot. That's the easiest way.
If you still want to use nandroid backup then copy the nandroid backup to the correct location... Head over to Philz Touch recovery and use the custom restore option by which you can select only the "boot" and "system" partition. But I haven't tried doing it so can't say whether it will work or not. However, technically it should work. I have no idea how to do this using TWRP though as I haven't used it much.

[Q] Corrupt Recovery

Hi Guys
Originally unlocked and rooted my nexus 5. Then the OTA update seemed to remove the root. I havent really looked into re-rooting but i need to wipe the device and I thought I may as well do it now. Having issue though
- Device is still unlocked when I go into the bootloader I see its unlocked
- Try to flash a custom recovery and when I follow the steps it goes to red exclamation (Im assuming meaning corrupt custom recovery, probably the old CWM before the OTA)
- Read through forums and they say I need to remove reboot-from-recovery.p file from the /system
- however I cant remove it without root and I cant get root without removing it
Whats the options here?
Thanks

the exclamation point is the stock recovery. once you take in an ota, it removes both root and your custom recovery. to get your custom recovery back so that you can flash a bootloader(and the supersu root binaries). you can flash a custom recovery while youre in your bootloader via fastboot on your desktop.

Can i go back to cm11s this way?

Hi! My question is lame, i know.. But here it goes anyway, i couldn't find a simple and direct answer..
Is less than a week that i have this phone, and i've been reading a lot of guides of how to rollback to cm11s.. the thing is i've flashed the latest CM12S signed zip ota through CM Recovery, everything is fine as i'm testing it right now..
My question is: if i want to go back to CM11S (in the case that i don't like CM12S or have some bugs), can i just wipe data / factory reset and cache in CM Recovery, and then flash the cm11s signed zip?
I haven't rooted or unlocked bootloader, is it relatively easy from what i read around here.. but i wondered if i had to go through all those steps (unlock bootloader, custom recovery, and then flash) or just doing the steps mentioned before will work just fine..
Is it better to fastboot flash or through custom recovery is fine also?
Thanks in advance!
PD: I'm also asking what do you think about some other 5.1.1 Lollipop ROM, custom kernel, etc.. I'm kind of a flashaholic and i would be able to install the custom recovery if would be really worth it

Just unlock your bootloader now, the longer you leave it the more difficult it'll be to backup your internal storage beforehand. You should really have it unlocked anyway as insurance against anything going wrong with your phone. Once you have unlocked it you can flash TWRP recovery, then the correct procedure to go back to CM11S would be to perform a full wipe (system, data, cache, dalvik cache) and then just flash the zip. As far as custom ROMs for this device go, there are many excellent options to choose from that offer extra customisation that you won't find on the stock ROM.
Don't we have to flash the firmware prior to flashing back to CM11s to prevent a hardbrick? I'm looking into doing this as well, so I'm just asking for my own clarity.

The firmware is contained in the official zip.

Thanks! Stupid question, but can you please link me to the official zip? I already have TWRP installed, so it would be nice to revert sooner than later.

Thanks!
Thank you both, i believe that this week i'll have some time and unlock the bootloader and flashing the TWRP recovery right away.. Then i'll see which ROM suits my use (i'm looking to battery friendly and high screen on time, will see the forums accordingly) and start the journey on this beautiful and well supported device
Also, thanks for the clarification of the modems.. Will be looking after that and make sure not to miss that step if required :good:

Once you've flashed the ROM, please do share your results. I am still unsure if reverting from a Lollipop ROM to CM11S will cause issues with the radio and/or a softbrick of the device, as I've read that this "can" happen.

Reverting from Lollipop to KitKat won't brick your device, whoever said that is wrong, and would have caused a brick because they didn't know what they were doing. You do need to make sure you flash a KitKat modem though, otherwise you'll have issues with the prox sensor.

Thanks Timaaa...last question, I'm downloading the latest modem from this thread http://forum.xda-developers.com/oneplus-one/development/rom-stock-rooted-xnph05q-t3027033.
Is this the correct flashable modem file to use, or do you recommend another for XNPH05Q?
