Water damaged Phone repair | Need Help - Huawei Y7 (2017) Questions & Answers

Good afternoon Guys,
i have a Huawei Y7(2017) thats waterdamages(drove with motorcycle in rain)...
I already know the following:
The Waterdamages was months ago.
When the Battery is Plugged in it wont turn on, when you try to charge it, the LED Indicator flashes red.
When you unplug the battery(yes phone is open) it turns into bootloop when you put in the charger.
And i get it into fastboot mode with powerdown + power.....but my computer says that the USB Device wasnt reconized correctly because it dont work correclty(dont say xD)
Yep, i have also already completely disassembled the phone and removed any corrosion caused by the water(the most was near the battery plug, but havent found that much. Under the protection where CPU, Ram usw are werent any water indicators(corrosion)...
Does anybody have any idea ?
LG, Thiemo

Gave it a alkocol bad(97%)....didnt changed anything......i dont think its anything with the hardware...i think the water damaged something on the rootfs that caused the bootloop.....and something that is important to get a connection between pc/phone cause windows says that theres an error with the device and that is probalbly not working correctly.... meh :/

Just got it to boot(plugged our battery, but charger in(bootlooping, and then meanwhile put battery in(yes in know VERY BAD IDEA))...but it actually worked...it booted...any instantly shutted down because of too low battery...now same problem

[Q] [i9023] Water damage - USB won't connect to PC.

Hi there,
My Nexus S (i9023) phone recently fell into a water bucket and I immediately pulled it out.
Not much damage was done to it except of one thing: after I put it in a bag of rice like stated on the internet for overnight, and then plugged it in again to the charger, it seems like something was different.
When I plug the phone to the AC power - phone DOES charge, but nothing else happens.
It doesn't turn on screen and informs "charging", and doesn't have the "charge when phone is off" option anymore. Instead it would just turn the phone on.
Also, when connecting the phone to the computer nothing happens, it's just charging the phone! can't mount USB anymore
I took the phone to a lab which handles these cases. They replaced the USB port and cleaned all the corrosion. They said it's fixed now, and indeed the USB port is new.
But then after coming back home it's still the same.
I'm sick of being dependant on other people and would like to fix it myself.
Any clue which part of my phone was fried? Where can I get it?
Thanks!

Are u rooted?
Try a different ROM. Maybe one ur ur backups.
If it still does connect then it has to be the ROM assuming ur computer has the proper drivers still.
Good luck

Thanks!
Thank you!!!
Problem solved after I loaded one of my backups.
Any explanation to that? even when the phone was turned off it couldn't charge it in off mode and now it can.
How come it's a software issue?
Thanks!
I can only guess that ur ROMs kernel had a "fast charge" option. If so this doesn't allow computer connection. How it got switched to that option... who knows .... maybe the sudden power surge.
If not that, then ... strange things happen when a phone get wet.. the sudden power surge could have changed the power output causing CPU adjustments... who knows.
I'm just happy it worked for u.
I'd recalibrate ur battery asap.
Good luck
Vs Nexus S 4G
Hi, the same thing happened to me, only it wasn't a bucket, it was a pool, and changing the ROM didn't work (I've flashed at least three different ROMs since then, kind of hard when the USB port doesn't work but eh, what can you do).
Also, it's on a Gio, not a Nexus S, but the principle should still be the same, yes?

Phone dead (Dont turn on, pc wotn recognize it)

Hi guys, my little cousin have this phone and ive been tweaking it for him since he bought it like year and a half ago. Th phone was on CM11 with the mount sd script and it was working fine. Now suddenly stopped turning on. My cousin says he was charging the phone being off and that it reached 100% in about 30 minutes what it was weird he says. He unplugged the phone and now it dosen't tur on, the pc dont make any sound when is plugget into it nor shows anything in the Windows device administrator, the charger don't make the screen turn on. I tried 2 cables and 2 chargers. I think that the board got fried maybe a electrical fucltuation in his house, an overvoltage, dont know how you guys call it, we're from venezuela. Any help or explanation will be welcome.
Sorry for my english.
Well, I've found that off-mode charging was a bit buggy in CM 11 but didn't know it could fry a board.
Try to do current flush :
i. take out the battery
ii. try to switch on the phone (battery being removed) by pressing the power button for 3-4 seconds.
iii. reinsert the battery and switch on the phone.
----------------------------------------------------------
If this doesn't work then sorry it maybe a hardware fault.

Sudden Death Z3

Hello all,
For some strange reason my phone died on me friday, the last time i saw it on was while updating.
It wasn't charging at the time so i thought maybe the battery ran out, but when i connected it with the charger my phone wouldn't boot correctly.
My Z3 was in a bootloop, it could still be detected by my pc but i couldn't do anything due the fact it was turning off and on all the time.
I tried to enter recovery mode but it instantly restarted itself...
Pc Companion wasn't detecting my phone so i couldn't use that.
since my phone did get repaired already (my screen broke) i could manually disconnect the battery but that didn't work either, i tried a new battery too but to no succes.
I also tried all the button combinations, the only mode i could enter was fastboot mode (blue led) and it would stay on but still no sign of a normal booting process.
The yellow button near the sdcard slot didn't work either.
When i put my phone to charge at the wallsocket the led stays red and it won't reboot all the time, but after 15 minutes the red led disappears and it seems like the phone isn't charging at all.
Today it got worse, my pc can't detect my phone anymore and the bootloop stopped too, the led stays red when charging (usb and wallsocket) but after some time the led disappears.
I can't enter fastboot mode anymore.. plainly said; nothing works anymore.
Anyone knows how to fix this problem?
Sony doesn't want to repair it for me since i fixed my screen externally so i hope for solution
I had a similar behavior on a Xperia T when my battery was deeply discarged.
There was No way to load the battery inside the phone.
The phone has to start the bootloader or something like a "mini kernel" (dunno how it is called exactly) to start the loading sequence.
If you are under the -normally not reachable- minimum volatge (under normal conditions phone turns off before) there is too less juice to turn on the booloader and start the loading.
In my case I opened the phone put out the battery and charged it directly with a power supply by wire.
For me it worked.
I see you write that you tried other battery was this one full for sure.?
regards

I assume that you know that... but nevertheless
I advise you to be very careful with li-ion batterys the
are very sensitive with charging voltage.
There are some tutorials on youtube but do it on your
own risk I´m not responsible for anything...just saying.
Edit: for safety...I think it would be good to try to load the
li-ion battery only that much that it has enough power
to boot in the loading state...then put the battery back in the
phone and load it the normal way.
I wish you a succsessful charging let me know if it worked.
good luck :fingers-crossed:

Battery completely dead or other hardware issue? [semi-resolved]

Hi All, my wifes s6 (using xtrestolite rom) has stopped taking a charge. Im trying to figure out what the issue is. Unfortunately im travelling for the next month so have limited trouble shooting options.
Background
- wife has been complaining that her phone battery dies quickly. I kind of dimissed her assuming it was in her head. she said it loses 10percent in standby mode in 1hr roughly. Shes been complaining about this for a week.
- yesterday at the airport her battery was at 12% and when we plugged it in to charge it wouldnt take a charge. Bolt icon did not come up and still said "connect charger" on the screen. Normally when connected the red Led comes on, but now it doesnt.
-our normal chsrging method is using and aukey 3port charger as fast charging mode.
Troubleshooting/diagnosis
- i have an s6 as well so i tested all the cables and chargers on my phone and it works. We even had the official samsung charger and cable but same issue.
- after the phone was completely dead, if you plug in the charging cable the charging bolt icon comes on for a few sec, the top left says "kernel is on seandroid enforcing" for a sec and then everything goes blank. Red charging led doesnt come on. So it seems like it detects the cable but wont charge enough to boot up.
- i was able to boot into twrp recovery but where its supposed to have a battery level its completely blank. Originally i was able to do this without any canles but then it wouldnt. My guess is that i orginally had a bit of juice and then it was completely dead.
-after leaving it plugged in for a sec, im able to turn it on where it boots and i can see it says 0% battery. It stays on for 5sec before turning off itself.
- i also tried plugging it into laptop, but laptop does not detect it. The phone does detect the power though and does the same as above but this time bolt charging icon stayes on for 1-2min before going off and seeing the "kernel is on seandroid icon". Once the seanadroid goes away nothing seems to happen. After doing this i was able to turn it on and it showed 1%. I thought this was promising but after trying this a few times ive never been able to get to 1percent again.
- with the brief charge thst i guess its getting, i was able to go i to twrp recovery and do a factory reset. This was with cable plugged in the whole time. Without cable in i dont think it would complete the action.
That about summarizes whats happened.
Ive concluded the following:
- charger and cables are ok and not the issue
- it is not the charging port since the phone does seem to be getting some juice bacause charging icon comes on for 2sec whenever cable is plugged in.
- its not a software/app issue since it wont charge even in recovery mode. Also factory reset was done and no luck.
My best guess is that the battery can only hold a 0-1% charge which is enough to register it being plugged in but not enough to do anything else. But if everything else is ok shouldnt it work when if the cable is just left in. This makes me think theres something else going on.
Any suggestions or theories would be much appreciated trying to decide if i should pay to get battery replaced.
Sorry for the long post. Figured it is best to give all info.
Thanks in advance!
Update June 3:
Hey everyone, just a correction on the above. It looks like it is able to charge in recovery (slowly). I realized that although there is no battery level during recovery, no charging led, and not booting up after being charged for a bit, maybe its just going slowly.
So i went into recovery and left it overnight on the non-fast charging and woke up after 8hrs and it was at 78percent!!!
Im not sure why it didnt go to 100% in 8hrs.
The phone still doesnt charge regularly when plugged in, so still need to fix that.
Do you guys think its a rom issue (only factory reset done before) ? I will see if i can get a rom for flashing.
Update 2:
Reflashed xtrestolite rom but still no luck. It wont charge.
Seems like a dead battery.

Bump.
Went to the phone store and they said its probably not the battery but the ic chip for charging? This will cost 150, but doesnt include the screen if they break it...
Does this make sense since i can charge in recovery.
Thanks. Any direction or input is much appreciated.
Go on the local store and change your battery (if isn't in warranty)
Hi all, just wanted to update the post that the issue is semi-fixed.
I brought it into a repair shop who offered to diagnose the problem for free before paying to replace the battery.
He told me there was nothing wrong with it and not sure what my issue was. Plugs in the charger and lo and behold it was charging. He said he didnt do anytning to it except blow some compressed air on the port.
Im guessing the comporessed air cleaned out a short? So now it charges properly.
The issue remaining is that the pc doesnt detect the phone. It shows as charging on the phone but no conmection. Tried to install the latest samung driver (1.5.4xxx?) but no luck. On occation sometimes it says "usb port has malfunctioned" but other times nothing.
My s6 does actually connect, so definitely my wife's s6 itself and not comp. Im tempted to buy some comlressed air and give it ankther blow, but dont want to risk messing it up again. im pretty happy that it at least charges up.
Hope this helps others that might have similar issue.

Z3 Death discharge problem

Welcome, i've readed alot of topics on the internet about problems similar to this, but nothing fixed my problem. I've tried connecting to wall/pc charger, power button + volume down/up combinations, really all the thing.
Couple days ago after my phone fully discharged ( I rarely had situation like this, I usually charge when my phone have 10-15%, but this day I couldn't. ) I came back home and tried to charge my phone, red light was ON but it still didn't charge after alot of hours. I then tried to fix it, turning on phone etc. but screen was always black and phone didn't want to charge. At first when I tried to boot the Z3 red light was blinking, but after some time it stopped. I ordered new battery, replaced it carefully (though it's battery problem) - then when I connected the new battery for the first time I though I have fixed the problem, battery charging icon showed up for a moment on screen, I was very happy. Then I disconnected charger so I could assemble my phone. Now when I try to charge my phone problem is this same.. like with old battery - Just red light, not turning ON, not blinking. Powering up Key combinations with volume don't fix it. My PC Companion don't see phone. I disassembled my phone again, disconnected battery and connected it - It didn't showed any battery icon again, so why it did when I connected it for the first time? and why when my phone died for the first time red light was blinking, now it doesn't? I want to add that I never dropped my phone or used it in water - never, thats why I was almost sure maybe just battery died after it discharged.
Btw. Important thing is that USB port isn't broken, red light is always ON when I plug USB charger, but when I try to use my magnetic charger, phone never respond - no light. I also tried different cables, chargers etc. Could it really be something with the mainboard?
What could've happen? Why my phone went dead after fully discharged it ? Why battery replacement doesn't fix the problem? I don't get it, is mainboard damaged or something? Can I still try something? Maybe anyone can help me.
Please :/ I cannot afford a new phone right now, really want to try fix it, maybe somehow connecting USB cable straight without usb port can fix it? I heared people do something like this.
