1st Gen Screen off but vibrate and system still on - Huawei Watch

Hi there.
My First Gen Huawei Watch suddenly turned off its display today and even though it's off I can still feel the usual haptic feedback of the unlock code and the do not disturb modes when I click around on the dark display.
Everything seems to be running normally apart from the screen which only is displaying black and won't turn on.
I have tried long pressing for a forced restart and can feel the usual vibration when it restarts. No Huawei logo or Wear OS logo is visible either.
I have let the watch drain and when connected to charger the screen is still off.
Randomly a few hours later the screen came on again only to go off after a few minutes again.
Any suggestions?
Thanks!

I had this same problem - it was due to water getting into the watch and causing corrosion between the touchscreen connector and the metal back of the watch. Ultimately in my case the battery was bulging and forced a gap between the frame and the back. If you're handy, watch some videos for opening the HW1 up. It's honestly very simple to do - but note that the screws on the back of the watch are Torx T2 NOT the T3 which some online guides say. Get some high % IPA and Q-tips and clean the connector a bit. I repositioned the insulator pads to cover the corrosion part and watch worked good as new.

[Q] Desire HD very sick - need repair help

Hiya,
my Desire HD got wet in the front pocket of my fleece, not drowned just some droplets of water that got inside the Otterbox case and into the phone. I did try and turn it on before I realised it had got wet, it wouldn't power up.
I removed the phone from the Otterbox and dried everything and tried to turn it on again as there was only very slight traces of moisture apparent. There was condensation and a couple of little drops of water inside. I discovered there must have been enough moisture to short out the battery as there was a little residue mark above the contacts on the inside of the casing. I then noticed the liquid indicators had turned red.
I removed the battery cover and dried the phone gently using an electric room heater for hours, I also put the phone in a bag of rice for a couple of days.
I tried to power it up again after a few days in the rice and it wouldn't start up. I measured across the battery contacts with a multi meter and found the battery was open circuit, so I know it must have shorted. Hoping that this was the only damage I bought a new replacement battery. When I fitted the new battery nearly a week later and switched on the phone, everything seemed to be fine but the display seemed to flash, and as I had a Leedroid rom installed I heard R2D2 chirping and could see the device start to boot up as normal on the screen. Then the display went dark and hasn't worked since. I stripped the phone and cleaned a couple of patches of residue, one of which was right in the lcd connector.
Now when I try and start the phone there is no display, the phone vibrates once when I hold in the power button. Approximately 40 or 50 seconds later I can hear R2D2 making his tweeting noises which always happens on boot up. I didn't think it took so long to hear R2D2 but maybe the phone is checking the file system or something now, and I just can't see it.
It may be that I just need a new screen & digitizer to repair the phone, but I can't tell what might be on the display - maybe it's the phone unlock screen asking for my pin number etc. I can't see any image on the screen, that you would normally see when the baclight is faulty, I have tried to view it with a desk lamp, but it's just black. The capacitive buttons at the bottom don't seem to have any effect, perhaps they are not enabled if it's sitting at the password screen, if it is at that screen.
The l.e.d's don't light up at the top when I turn it on or plug in the charger.
I might have also damaged the volume key switch/ribbon slightly.
What would you do with this phone, any advice on how I could proceed ?
Would it be working just with no display, as R2D2 is squeaking(Leedroid rom has this when the device boots and has an animation of a pc booting up with the post screen) ?
No l.e.d's is a bit worrying and it doesn't seem to know when on charge etc. but perhaps they only work once the phone has booted, I can't remember DOH!
I just thought I would ask, as there are a lot of knowledgeable people on here and it might be possible to save my droid.
Grateful for any help or advice
kind regards

[Q] Touchscreen sensitivity problem. Microphones problem.

Yesterday I accidentally dropped my phone in the basin and about 30% of the upper part of the phone submerged into the water. I quickly picked my phone up and the screen started to blink. The phone shut off not long later and the first thing I did was to remove the battery but it was non-removable. So I screwed out the nuts and remove the inner cover and pulled out the battery. Then I carefully took out all the components inside (panels, camera, speakers) and used hairdryer to dry them out. After all, I assembled back all the components and hoped it would work. Thankfully, the phone was alive again and everything seemed to be like normal but then, I realised my gestures couldn't be detected on the right side of the screen and my microphones weren't working. Any way to fix it and what is the price for the spare parts? Below is my touchscreen service test.

Moto Z Play was partially submerged in water, condition deteriorated, won't turn on

My wife dropped her Moto Z Play into a puddle and the bottom half of the phone was submerged. Initially the phone continued to work and she wasn't concerned, so she did not properly dry the phone off. Eventually the screen stopped working and she plugged it in before she told me about it. I dried the phone off as best I could, removing the cover and taking out the sim card. I placed it into rice, where it has been for about a week now. The phone will not power on at all, it makes no noises when plugged in (the phone usually makes a high pitched, very quiet tone when charging). The forward facing light does blink white when it is plugged in but it makes no other response. I do not know what that means and I have not seen anything about it at any forums. The battery is not removable. Any suggestions on what to do now and any explanation on what the blinking white light means? Thanks
same exact situation...
Same thing happened to a friends' moto z play this weekend when she was tubing at a local river. The battery had died so her's was not on when it hit the water and was only submerged for a few seconds. She dried it off best she could and plugged the charger in to see if it would charge. It just blinks the white light on the front three times and then the battery lightning bolt graphic displays momentarily and repeats this. Phone will not turn on as well. We haven't left it on the charger for any period longer than a minute or two. Found this thread, looking for similar situations hopefully for a solution.
FWIW - we did find this youtube video water testing the Z play and it seems as though this phone should be relative water resistant.
since i haven't made 10 posts I cant include url but if you enter watch?v=dxvLKskmkg8 after you tube dot com you can find that video. THIS IS NOT SPAM and very relevant to this thread.
Thanks for sharing @ABTF16 anyhow... Hopefully someone knowledgeable to this scenario will be able to provide an answer at some point in the near future.

Quite weird!
It passes the water test with no problem.
Speaker working fine camera working fine touch working fine.??
And in the video he said that the Motorola claims that it has advanced nano coating technology which can protect it from accidental spills or splashes.
Trust me, my Moto X Force went the same way
One second drop in water, it was upright and it was only the bottom inch and for less than one second as I immediately removed it, continued to work for the rest of the day but died in the evening and would not turn on
Sent to Moto and returned with 'unit beyond economical repair' along with a photo and half of the components were corroded
WTF!! one second in water
Don't get me wrong I love Moto's (I have a Z Play now) but they are rubbish if they even get moist
If your phone gets wet you are supposed to leave it off for at least a day in a dry area. I left mine in a hot car with leather seats. You need to let all the components dry out. You could achieve the same affect with a hair dryer.
Turning it on, or trying to charge it is no good idea.

I had accidently taken my MZP under a running tap and with the pressure the water went all the way inside my MZP but then at first it worked fine for 1 hour or less. Then it switched off automatically and started rebooting. I still managed to get it on then it started to show results like camera stopped working and fingerprint scanner stopped working. I shaked the phone and then removed the water which was remaining. Then I managed to switch it off and then put it in rice for 2 days. After that its working fine, only fingerprint scanner was not working but yesterday it started working and now everything is back to normal. Try isopropyl alcohol which is 99% pure alcohol and then dip your phone in and then put it again for 2 days in rice. I hope this works. However I just needed rice to do its work and mine worked. Hope yours work but if its damaged go to the service centre asap.

Got an interesting problem.

Hey there. I'm a bit new to this side of XDA. Honestly with how long I've been AWOL from this site nothing is familiar anymore. How time flies. Well my first post back in years couldnt be more unfortunate phone wise, I've had my Z2 for a couple of months now and as a mechanic it's been treated like all my others phones prior, rough. I've been locally recognized as the guy who has a new phone every couple of months because he can't not shatter a phone. An expensive hobby of breaking phones. Well luckily I didn't shatter my Z2. I just water logged it. Gotta change things up right? So here's where the interesting problem comes in, I let the phone sit in rice for 30 hours, switching the rice out half way through. It acted up like you would expect in the first couple of hours but then stopped. When I pulled the phone out I scraped the rice out of all the books and crannies and tried to power it on, to no avail. Dead battery I assume, so I plug it in. Charge icon pops up, a sign of life! How glorious. So I let it sit for a minute as I assume the battery probably dropped below minimum voltage when the LEDs were freaking out. Went back to the phone, held the power button and no screen, but "Hello, Moto!" So at this point I'm convinced the screen is dead, so I force it off with the volume down method and pry off the screen. To find what? More water. Good Lord. This phone is incredibly water resistant just in reverse. So I do the only thing that makes sense at this point, I remove the ribbion connector from the board for the display and put the phone back in new rice as 2 separate pieces. I then leave it in there for another 30 hours switching the rice halfway. Bringing us to now. I took the phone out, cleaned all the rice out of the 2 pieces and off the remaining adhesive and connected the ribbion back to the board. Plug the charger in, and again, charging logo. But then I hold the power button and the TMobile splash screen pops up! Then the screen goes dead and once again, "Hello, Moto!". But whats different is now when the boot sequence is finished I can interact with the phone and it works, shake for flashlight, enter my passcode (just by feel cause I'm good like that, ladies hmu), and the button responds with vibration. The phone is working but no screen. So at this point I'm sure, the display driver is done. I murdered it in cold daylight. So I shut it off and start looking around for new screens, in the midst of this I knock the phone and accidentally hit the power button, and it starts to boot up. T-Mobile spash screen, screen death, "Hello, Moto!", and nothing. Now that seems weird. Why would it work twice on the TMobile splash? So I decide I'll try putting it in fastboot for S&G's. Restart, put it in fastboot and the screen stays on. Beautiful and clear as day, all buttons work, everything reads fine, but, if I go to boot it or do anyother action than "retart bootloader", the cycle continues. T-Mobile, death, hello Moto, nothingness. Now at this point I'm okay with the phone being dead, it's fine, but I'm intrigued now. What would cause the screen to work just fine when in the bootloader and the TMobile splash screen, but die when it boots? The phone is very clearly working in the background. I logged in, used Google assistant, used the flashlight, pressed buttons on the dialer, all without the screen but with haptic feedback and audio. Could the graphical side of the main partition just be corrupt, or maybe the display driver is dead but the main board interacts with it differently during fastboot? I'm far from being knowledgeable on the hardware side of these things but I'm really genuinely interested in getting feedback here from anyone with an idea of what is going on. I'll post a video here in a half an hour or so when I finish up with dinner.

Well... It sounds like there is a short between the screen and the main board. It could have happened when you plugged it into power while parts were still wet causing a short to ground and frying a chip that controls display but not touch on the screen.
Best way I can describe it for you is if an ECU on a car got wet and shorted out. Everything works but you get an engine code for TPS sensor failure due to said short. (The ECU can't read TPS due to a short). That is what seems like what happened.

Well see I would think that as well but the screen does work. Just only in fastboot, and the boot logo.
I got the video here.
Fastboot is a pretty low level and most likely uses basic hardware. I mean really what is there to see but a simple background with some text. Once you load the OS then all the hardware and it's drivers into play. Have you tried booting into safemode? Ultimately you'll probably have to repair or replace, but there could be a slim chance that there's still a little moisture in there and it still has a short somewhere.

Galaxy watch SM-R800 won't boot

I am having an issue with my Galaxy watch SM-R800, it was working perfectly a week ago and it suddenly turned off. When I press the power button it shows the splash screen with the text Galaxy watch for a few second and then turns off, I have tried rebooting and this has resulted in the same thing. I have also tried to factory reset the watch and the same problem occurred, flashing the rom resulted in the same. I have also tried to let it charge the entire night and when loading up wireless download option it showed that the battery is full also when placed on the charger the screen turns on showing that the watch is charging it shows the percentage and then it turns off again. I do have to note that when in fastboot mode or when in wireless download the watch runs normally without turning off. I have not been able to find anyone with this same issue so far and even the ones with similar issues didn't want to offer any help. If you guys have any ideas or solutions please let me know.

My Galaxy watch 46mm is also in the same case and I also do everything to start the watch, nothing to do: flash (the bypass menu works well, the connection by wifi is established no problem), wash, change the charger, it started only once for 10 min, and it came back in the dark .... Is there a solution ????
Is there anyone who can help us and thank you
After three days on the doc "without power", I washed it with soap and dried it with a dryer, after two hours I reset it under recovery mode, hop the beast starts... I'm impatient if it holds up or if it comes back to the dead screen.
After 10 hours of operation, it fell asleep with the black screen "dead"... so it's not a success. thank you samsung for sucking our money for a gadget that loves its charging support without being able to wake up..... after a day, two, three or maybe eternity... Decision, I'm going to change the manufacturer either Huawei for battery life or apple for design.
After 18 days, I tried all the resuscitation procedures, none of them succeeded in making the "beast" watch starting, so I decided to wash it, I immersed it in a cup: warm water + vinegar for 15 min and a "hot" drying with dryer for 5 min and another "cold" drying of 3-5 min, the beast finally started...
It is under test ...
Has there been any more progress made on this issue lately?
I have an SM-R800 46mm with the same issue. Everything works fine in Download and Wireless Download modes. Recovery mode does nothing other than switching off the watch.
The watch turns off after the first logo is displayed so i know the watch is working.
I can also flash multiple firmwares via Wifi (AP mode) and these all complete and pass ok using NetOdin.
The battery has been fully charged and then completely drained to 0% over a 2 day period, then fully charged again. I have even tried turning on the watch while on the charge dock, but no dice.
To me it looks like there is some sort of issue with the boot loader that is not completing initialisation to proceed to the next part and complete the boot process. - Is there anyway of enabling a log trail on the watch, or would this need debug mode to be switched on (Which is impossible if the watch does not boot)
My wife has an SM-R815 that shows the initial Samsung logo, then a smaller Samsung logo, then the watch face. I have not messed with her watch as it is fully working and I don't want to break it.
What would Samsung do to the watch if it was sent to them for a paid for fix other than re-flash it? Do they have magical firmware or would they just replace the internals with a working board?
Looking inside the back case, there does not look to be anything damaged with the circuit board, and the battery does not seem to have expanded.
I am also dubious about the solution to immerse in water and vinegar ans would probably try Isopropyl Alcohol instead?
It is frustrating that this watch is only 3 years old and now unusable.
Allready tried Combination Firmware?
To check if something is dead or half dead...
Best Regards

Yes I tried the combination firmware, but it still would not boot. At weekend I tried to downgrade to a lower Tizen version and something bad happened and now the watch only shows a flashing yellow screen I have ordered a usb cable to try and re-flash using Odin instead of Net Odin, but the cable won't be delivered until Wednesday 19th Jan. Will update here if I get any success.

After 5 months (October 16-March 16) the watch works without problem, and that, after its shower with: warm water and a small amount of vinegar followed by drying with a hair dryer and a hard reset.
FINALLY, I BELIEVE IT'S A PHYSICAL SOLUTION

I confirm that this is the right solution "for me it worked" and you have nothing to lose...
Take my advice that I posted last October 16 2021 "so far the watch is working wonderfully".
I got same issue trying this Ludacris idea but didn't do nothing
I got the same issue today. when it first happened I was able to reset it and after an hour same issue. Hope someone by now has been able to find a solution for this.
I can confirm I have resolved the issue with my watch using contact spray to clean the internals. Water resistance is probably no longer working as i had to open the watch, however it now works great, 1 month so far with no crashing or boot issues.

when the problem started, was it due to being in contact with water? mine started when I started working out with it and got drenched in sweat.

Yes first time it happened i was washing my hands. After that it would do that at random, i tried flashing every ROM but the issue wasn't resolved. I would only get it to work by disassembling it apart and reassembling it and sometimes applying pressure light pressure to the sensors would get it to work for a few days. After i cleaned it with the contact spray i started working perfectly even when in touch with water. If you plan on using contact spray i would advise you not to spray around the battery contacts or the battery itself and wait for about 5 minutes to make sure all the spray has evaporated and there is no residue before reassembling and powering on the watch

I got mine to work. I just used a different charger and cable but still used the original charging dock. Thank you for the great info though. I guess my problem was the charger all along and not software or water damage.
