It is very hard to understand what your exact problem is, I can suggest a Galaxy III for an upgrade. As far as your current phone...
I;m sure someone out there has had a problem close to yours, try YouTube and Google searching as well as educating yourself here (XDA) on anything related to your phone or similar problems.
You might find the info. you need in an unrelated post or video! Check your pins to see if they are worn or possibly broken (connections). Ensure that you are getting a clean and solid connection.
Good luck

[Q] Huawei Honor U8860 Blue Screen CWM?

Hello XDA, I have a problem with my newly acquired phone that I'd like to ask you guys about.
I'm not exactly a noob when it comes to rooting and flashing android devices, but I've researched and scoured the internet about this problem!
It seems that whenever I try to boot my phone into recovery (CWM), it just flashes the Huawei logo and shows a bright blue screen for an eternity. What's the problem here? I've tried several recovery.img files, but they all seem to do the same thing... I'm on B919 so everything should be all set. Do I have to go through all the steps again and hope for another result, or am I doing something wrong?
Please help! It'd be appreciated a lot!

what did you do to your phone for this problem to appear.
flashing a stock rom through odin or smart switch should solve the problem.

Bootloop ... fail to flash with Odin .. please help

Hello people.
Another bootloop .. I'm sure it's the thousandth post about this problem .. but there ... I don't find myself anymore. Sorry for the rehearsal.
I detail:
I have a Galaxy S8 + (that of a friend) which remains blocked on the first screen .. so in bootloop. According to him it happened after an update attempt.
I tried all the attempts with Odin which all ended in failure (FAIL) with different BLs, some of which were old ... in short, I have a hard time.
I tried to follow the video which deals with this problem and how to get around Odin's failure .. nothing to do .. I couldn't do it.
So if you will be kind enough to help me get the phone back, I will be grateful.
To know that it is a model: g955nksu3dse2 therefore under android 9 Pie.
I’ll put a picture of what’s on the screen when I want to flash the BL for information
Thanks again.
