[Android Q&A, Help & Troubleshooting] yeshayh:
hello to all guys

A few days ago I decided to install lineage os to my second phone that is the same as the first (Huawei Y550 L03 which stopped working completely for no apparent reason, let me tell you how it happened, I was in the stock and started testing each rom from highest to lowest (android 7,6,5) after that I decided to return to the stock rom again because all the other roms had overheating issues, failures and bugs, after a few days of being using the stock rom, the wifi signal became weak, then I decided to reflash the stock rom, I did everything normal as it should be, erase cache, dalvic, data etc, after that I proceeded to flash the firmware with the sd dload method, started the process, advanced and ended suscesfully by saying that it would restart, they shut down to start again but never did it again, and did not give any sign of life, except that it appears as qualcomm 9008 in the device manager and with the emmc method in sd with the who phone starts and enters bootloader. I bought this second phone to try to revive the first one, how? enabling usb diagnostic mode to make a complete copy of the firmware, after having investigated a lot and tried everything, i could not get it to enter that mode, that's why I decided to install another rom with another kernel or boot believing that probably that kernel had that feature enabled and could make it enter the diag usb mode, but it also does not work).

So today I write to tell you about the issues what i have with this (or all)custom rom and that probably only happens with this model L03.

The image says everything, as i mentioned above, i installed the custom rom of [MENTION=4479868]desalesouche[/MENTION], i have tried two, first the lineage-14.1-20180812 and then the lineage-14.1-20180331, the only problem i have had, except for minor issues, is that the processor temperature reaches +50 degrees with the system running and without apps, but this does not only happen when the system is running that reaches +60 or +70 degrees of temperature, it also happens from turning on the phone and the logo appears until the animation, it feels that it reaches a temperature of +60 degrees, but that's not all, also in recovery it's always at a temperature of +50.

I have done everything to try to lower the temperature but I do not get it.

I wonder if those issues of overheating, failures and bugs could be due to the kernel model L02 and L03 is a little different from the model L01 and most custom rom are based on the kernel of model L01?, an example that each kernel could be a little different is that most people, if not all, that have models L02 and L03 are the ones that have had the most problems with custom roms, in my case, my first phone that i suspect, died to install these custom roms, and I'm not the only one, on YouTube there is a video of a guy asking for help to make a copy of the L03 firmware with the program qpts, he says his phone also died by installing a custom rom, but that's not all, in the comments section most say the same and about the same model L03.

So i want to know if it would be possible to compare the kernel of the two models L01 and L03 and see if they are the same or not and try to fix as possible the L03 model kernel, i can upload the boot.img file of the L03 model firmware if you want, i really liked this rom and I do not want to return to the stock but if there is nothing to do then i will return to that rom with a lot of lag.:crying:

Sorry guys but someone had to speak on behalf of all those people who have lost their phone because of installing these custom roms and that the cause may be the kernel of each model that are not equal and this could be solved and avoided reporting how i do it right now.:(

I want to know your answers and opinions and i hope you could understand what I meant, if not, please do not ignore me and ask me back.:highfive:

Thank you very much and sorry for my English, it's not my first language.
