boot-loop with cm11 legacy kernel

Hello, I installed last Legacy Xperia CM11 kernel:
Code:
# .fastboot flash boot boot.img
Then I reboot:
Code:
# .fastboot reboot
Now I have a loop in the mobile with the Legacy Xperia animation.
I try to install older kernel, but same problem. How could I fix this?
Thanks and best regards.

Did you install the ROM? That kernel works only with CM11.0 LegacyXperia ROM.

Hello,
I fix it installing older kernel, then install again the last kernel.
Regards.

After install the kernel you need enter in the recovery and install the rom (KitKat for this kernel). If you don't change the rom, the phone doesn't work. :good:

Steps required for correct installation (order is important):
1: Flash boot.img in fastboot & reboot into recovery
1.1 (optional): If the device is not booting, reboot to bootloader again and run:
fastboot erase system
fastboot erase userdata
2: Enter recovery, go to mounts and storage
3: Format /system, then /data and then /cache (Important step!)
4: Flash update zip
5: Flash gapps (recommended package is the one provided in the link below)
The non booting issue is right there in the original 4.4 thread instructions
If it still doesn't boot then rather than multi flashing Kernels, you should flash the stock ICS 4.1.B.0.587 full ftf firmware and start again from the very beginning

[Q] Boot loop and can't find appropriate boot.img

Hi
I've been given a One X (he bought an M8) and I thought I'd easily put on KK 4.4.4, but I have hit a brick wall.
It was running ViperX 2.6.0 with Hboot 0.95, and it's S-ON.
Well 4.4.4 needs a Hboot above 1.28, so the flashing failed.
So I did my homework and got the CID (it's HTC-023) to install the firmware so that I could update the Hboot via OTA.
So I installed the boot.img for the HTC-023 firmware and that (of course) was a an error as I didn't have a copy of the boot.img for the ViperX 2.6.0.
Then the firmware was a .rar file and didn't install anyrate.
So now it's in bootloop.
I have not been able to find a copy of ViperX 2.6.0 to extract the required boot.img
I've got TWRP with Sideloader installed, and ADB works fine.
So I am stuck (like my One X really) so any advice would be appreciated.
Thanks

Solution
I thought I should post the solution.
The essential problem was to get a Hboot 1.28 or higher so that a new version of Cyanogenmod could be installed.
On this page http://forum.xda-developers.com/showthread.php?t=1957376&page=189 is the following from ClydeB1
To flash you need to run the following commands: (It is advised to take a backup of your data and important files on your sd card)
1. Lock bootloader - fastboot oem lock
2. Boot to RUU mode - fastboot oem rebootRUU
3. Flash firmware - fastboot flash zip firmware.zip (if you get an error then rerun this command)
Note: The firmware will flash the new hboot, as well as a new stock boot.img and stock recovery.img.
To flash a custom rom you then need to do the following:
4. Unlock bootloader - fastboot flash unlocktoken Unlock_code.bin (you can use the same unlock_code file as you used previously, check your emails if you can't find it, or else reapply at htcdev.com)
5. Flash custom recovery - fastboot flash recovery nameofrecoveryfile.img
Note: If the unlock process wiped your sd card you may need to boot to recovery and mount usb storage to copy the rom file across again. If your phone won't boot into recovery then run command - fastboot erase cache and try again.
If you then wish to flash a JB custom rom:
6. Flash new boot.img from rom - fastboot flash boot boot.img
7. For good measure - fastboot erase cache
8. Boot to recovery and flash rom
I followed these steps exactly and it worked perfectly. I did need to use CWM as with TWRP the touch screen did not work.

and have more ease way to do this. You are with too low HBOOT and you can run RUU and then update the phone to latest JB because are you know witch HBoot you install to your phone

[HELP] Bricked OnePlus3

Hey Guys I need your help.
I think I bricked my OnePlus 3. (BTW yes its unlocked)
What still works:
1. Fastboot
2. TWRP and Stock recovery
3. ADB Sideload
I use twrp 3.1.0-0
Fastboot looks like this:
FASTBOOT MODE
PRODUCT_NAME: msm8996
VARIANT - MTP UFS
BOOTLOADER VERSION -
BASEBAND VERSION -
SERIAL NUMER - [censored]
SECURE BOOT - enabled
DEVICE STATE - unlocked
But I cant boot into any system. I think I corrupted the /data partition or sth.
What I tried:
1. Flashing boot.img and system.img via fastboot -> Result: Still won't boot. I get the Oneplus and android logo and a blackscreen after this.
2. Flashing stock rom / lineage rom / newest stock rom via TWRP Sideload or Stock-recovery Sideload -> TWRP gives me this error: Updater process ended with ERROR: 7
Any Ideas?

says "installation failed" when I try to install stock oos on stock recovery via adb sideload
edit: If I manually flash (via fastboot) boot.img and system.img and then twrp recovery twrp says I do not have a system installed. why that?
edit2: while flashing system.img it first says "Invalid sparse file format at header magi" but then continues normally. does this help?
