Help. I want to flash ROM :)

[Mysterka35]

So. After spending two months with this phone LE Eco Le S3 x626 64GB/4GBRAM decided that I should upgrade EMUI. because a few days ago when I was still in school my phone freezed and restarted on it's own. Everything would have been perfect but it started acting funny. It stuck at EMUI optimizing apps 2 from 2 about 15minutes with no sign. Then after loading to homescreen it freezed again after minute and continued this shit.. I found combinatio how to wipe data and now I want to share material and find some help from you guys:

Will this give miracle and well.. I upload Info about my phone. Now second question is what kind of equipment do I need? A PC? an USB cable that came originally with this phone? And.. well how should I follow that guide. What is that TWRP and how to well start the process

I wouldn't have said waiting 4 hours for free help, on a Sunday was anything out of the ordinary?

Yes, you'll need a PC and a USB Cable.

Also, TWRP is a custom recovery which is what you'll need to install the custom ROM. If TWRP exists for your device, you'll need to find the bootloader unlock method to flash that first, then your ROM.

Luckily there is OEM unlocking for my device under developer settings

"EMUI"?.....I believe EMUI is usually only found on Huawei and Honor(Huawei) series phones...like my phone...

Is your Le S3 already running a custom ROM that you flashed? I don't know what LeEco phones usually come with, but I know they're out of the smart-phone business now.

Just because you have this in your devices settings doesn't mean it can be unlocked. Bootloader unlocking is usually handled by the carrier brand.

 

[Mysterka35]

I mean EUI Version. Well... This phone doesn't look like it has been customly rewriten

 

[Mysterka35]

Yup. EUI. And besides I know that LeTv bankrupted..

 

[Mysterka35]

Still. If I do everything that has been said according to this guide.. Will I manage to upgrade without bricking my phone?

 

[Mysterka35]

I will look into a way about Le Eco bootloader

Guys, this seems like a decent guide for bootloader unlocking I mean. Now. Sorry to nag you guys but I never installed custom ROM before. But as for my friend I remember 2-3years or so ago I helped him with app called Odin, not sure what exactly he did to brick his Samsung galaxy S4? but anyway that being said I am sure that I need to look into these things carefully and nothing more nothing less from what is written on a guide
