Default [Q] [LB] CM11 install error, CM10.2 no boot; XZDualRecoverzy

Hi,

before I go any further: I have a locked bootloader and I'd prefer to keep it that way (company policy).

What I have: A C5503 phone with 310-GLOBAL-LTE firmware, XZDualRecovery 2.7.85-BETA.
What I do: Flash 310 FTF with FlashTool, then run install.sh in XZD asking it to root the phone for me. After reboot I get the CWM PhilZ recovery screen and after yet another reboot the system starts normally having the NDR app installed - it crashes sometimes though, so far unreproducibly.

Next steps were tried using all recovery options (CWM, TWRP, PhilZ) with full pre- and post- wipes, zips on internal storage.

When installing CM10.2.1 (latest stable) I get no errors but the phone won't even start normally (i.e. not even the SONY logo, just a short vibe, black screen). Fastboot and Flashmode both work, recovery does not.

When installing CM11 (140210) I get an installation error saying (roughly) "some error occured". It doesn't fit on the display but there is no useful information in it anyway. I'll copy it here if needed. After this I get the SONY logo bootloop with only fastboot and flashmode available, recoveries lost as well.

Q1: Is it even possible to install CMx with locked bootloader? I can't see why not as long as I keep the stock kernel..
Q2: Is it me or are there bugs in CM builds? How can I debug better?

thanks,

-mikky

1st: U can't. Actually it isn't necessary to unlock bootloader to install custom rom (e.g: custom stock based rom). However, the vital requirement to install CM rom is that u must have an unlocked bootloader because u need to install the custom kernel as well.

2nd:CM builds sure have some bug. You can debug it depending on how u customize the rom.

Interesting. Do you have any sources for that? I've been googling around and even though the custom kernel is part of the CM flash zip there is no information (to my knowledge), that CM cannot run on other kernels. On the other hand, there is no information it can....

It can run on other kernel with a condition that kernel is compatible with the rom. In your case, the stock kernel isn't compatible with the rom. If u r smart, then u can customize the kernel to make it compatible with the CM rom. Finger crossed.

Even if you can install the rom using the stock kernel, there will be high probability that many bugs will appear and you might brick your device sooner or later. There is a way actually to make it working on stock kernel by porting the rom. You can try it though. Happy goggling.
