Gentlemen and maybe Ladies, please advise if I am still able to do something with my friend's phone or whether I must give it back to him in the state to which I was able to bring him now. The whole situation is described below.
Honor7 Lite phone (new from the salon) in the second week of use fell into a friend's toilet. He put it in his breast pocket and bent to pick up the board. Unfortunately, the pocket has not closed. Before he could pick him up, the phone lay in the water for half a minute.
From what I know, it was about 2-3 days that he dried it and stubbornly tried to turn it on (unfortunately a basic error).
When I found out about this phone, I advised him to send it directly to CCS to Piaseczno straight away, because either there is a chance that the markers would not discolor it and they will make it, or they will issue a tolerable amount for repair. After all, the phone was under warranty and it was a shame to immediately disassemble it yourself. Unfortunately, after opening the site they immediately found flooding and unprofitable repair.
So the phone came to me as a potential corpse.
On a good day the fingerprint reader did not work, charging ended at 2% and could not continue to pull and the display turned off during operation and had problems turning it on again after clicking the power button.
After opening, I saw corrosion and other deposits on about 8-9 joints and components. I cleaned everything about 3-4 times in various combinations, using Kontakt preparations (61, WL, S, U), isopropanol, distilled water + brush. After all these treatments I managed to get rid of all visible (I pulled the screens) corrosion and brought back to life everything that did not work previously. I am aware that corrosion may come back over time, but the owner of the handset has been warned about this.
When testing everything for sure, it turned out that WiFi and BT did not work (gsm is working properly, I haven't checked the GPS yet).
The WiFi and BT icons are as if inactive. Like both can be clicked, but everything remains inactive. Gray all the time.
I read in the forum about the damage of this module, but I would like to exclude other things for now. I haven't thrown the disc into the ultrasonic cleaner yet. I am afraid for microphones, although I have already read here how to secure them. Is there any point in taking an ultrasound bath at IPA?
Or maybe something needs to be warmed up? What element on the board is responsible for wifi bt in Huawei phones. I have not found service lines for Honor7 Lite (European equivalent of Honor 5c), but I suppose that in most Huawei it can be the same element.
I am not a serviceman, I just often exchange displays of my friends with work displays or other components in small electronics at the cost of the material, as a hobby and not earning money, but I have already written about it here once.
