[Huawei Mate 10  Questions & Answers] Sydney_:
Hi folks,

First things first: I know there are a lot of threads concerning the "red light of death" for Huawei and other devices. I already read so many of them that my head is spinning xD However, I have some questions left and I need to distract myself from getting crazy due to the possible loss of data on my phone (and I have to wait at least until Tuesday for any news regarding the phone...)

What happend?

- Phone restarted while surfing

- Went into a bootloop

- Tried a soft reset

- Tried eRecovery --> Not succesfull

At this point I had to leave the train and the phone had turned off anyway. Wanted to charge the phone at the airport and back up recent data. Removed the protective cover and noticed that the battery was bloated. Since I was afraid I unplugged the phone and came to the conclusion that the phone doesn't work due to the defective battery. Back at home I ordered a new battery - didn't help. Phone won't turn on, softboot doesn't work. I only see a solid red LED when I try to charge it. Bought another battery - nothing. Went to a repair shop: This is the point where I start to have questions :)

They are all very nice at this place and maybe everything will turn out fine but I just can't wrap my head around certain things.

At first they also wanted to check for a defective battery and possible repairing errors since I replaced it myself. Today they called and let me know that the new battery is alright and they now want to order a new screen module. Later today I went to their shop to ask how much everything will cost and also to ask them about the procedure. I asked them why they want to change the display. Answer: Since the battery is fine, we believe the screen cable got damaged when taking out the old battery - its a common issue because the cable is underneath the glued battery. Once the new screen module is ordered there is a good change that it'll work and we can save your data. Note that I don't have to pay for the new screen, since I said that I only want the data back and that I don't need the phone back fully working. So I don't think they suggested it for the sake of making money.

I have indicated that I suspect a hardware problem, but the guy said the motherboard is fine. He continued to explain, that since the red LED is on and the mainboard as well as the battery are fine they assume a problem with the screen.

My questions:

How can they check if the logicboard "is ok" (I asked if they can do micro soldering and since they can't I doubt they can measure the components). Are there easy ways to exclude an hardware error on the board?

Is it possible that the phone doesn't start, vibrate, is not detected by the PC all because of a faulty screen? Any ideas why the LED is visible then?

Doesn't the red solid LED indicate charging? So how come I "charge" while not being plugged in? (LED stays red all the time)

My initial problem wasn't a possibly ruined screen cable/connection but a bloated battery. It just cracked the backcover open but nothing happened to the screen --> Is it possible at all that the bloated battery killed the display module?

If anyone has read this far: It would help me if you speculate with me about the problem, share your experiences or help me in any other way. Somehow I have to pass the time until next week and I'm going insane xD

Thank you so much!
