is my P10 plus dead? - Huawei P10 Plus Questions & Answers

Hello everyone,
i recently acquired a used P10 plus almost for nothing.
the guy i bought it from said it fell on a carpet and it wont turn on anymore.
the symptoms were:
*black screen
*red led blinking (first 3 fast blinks, later only 1 every couple of seconds)
So i thought to myself, probably battery issues from the fall, maybe it disconnected somehow.
I disassembled the phone, reconnected every cable, but still same symptoms.
i read somewhere that red led usually means battery dead or the small charging motherboard (?) is broken. So i ordered both from Aliexpress and installed them today, but still the same issue.
i connected the phone on the charger without the battery, the screen came on (but it seems its broken also - only vertical lines and a crack, lol).
Any ideas?
should i order a new screen and try to fix it or should i give up? (i read somewhere that people couldn't power up their phone after screen replacement)
thank you guys in advance!

well, i guess ill just give up.
i was hoping for an idea of what to do, but nothing.
a shame really, i was hoping to get it back to work again.
cheers!

universal dead?? HELP red light!!!!

Hello, earlier today i felt the device was very warm, i tried to switch it on but it dint respond, even to a reset. when i plugged it into the wall charger all i get is the right hand LED glowing red.
HELP!!!!!!!!!!! how do i hard reset it or get it to work again!!!!!!
i would call in orange care, but im out of the country and i really need the pda functionality!!!!
Unlucky. The 'red' light on most HTC devices indicates a serious power problem, usually it means that the battery is dead (as opposed to simply having run out of charge) or very close to death. You can probably get it working again with a new battery, if the incident hasn't damaged any other components.
i had this with my JJ after I accidently let the battery run down, I plugged it in and led went red and unit would not power on, left it plugged in started scanning the manual and web about a red led, 30 mins later, JJ just switched on and all fine.
It's worth a go and ive not had problem since
i dont think that was the case...
i have a feeling it might have been a short or something, because the unit was SERIOUSLY hot.....
nothing i did worked....until............
final time before giving up, the light was still red etc.
i figured what the heck, either way its dead and im going to get a replacement.
i then gave it fairly hard thump
the red light disappeared. i thought to myself, oh crap, i've really killed it.
then i reset it............. IT BOOTED UP!!!!!!!!!!!!!!!
and all my info still intact......brilliant.....im still going to try and get a replacement when i get back, but thank goodness.
and here i was thinking the last computer to respond to physical violence was the old 486'es hehehehehe

Actually, it's called percussive maintenance, "the fine art of whacking a machine till it works"
hehe, i'm an IT technician and it's the first thing i try, especially with Printers.....
They don't teach you that on MSCA courses.....
I would recommend not using the machine too much until you can get a replacement battery if I were you. Lithium batteries will get very very hot (in some cases expand and ignite) if they are dis-charged too far. Most equipment which uses lithium technologies will have a voltage cut-off on the power input. As each cell is a nominal 3.3V-3.6V, this is often at around 3V in order to not discharge the battery too far. I would have hoped that this was a HARDWARE function rather than software. However with what you have described, if the voltage cutout was somehow disabled, then this could explain the problems.
Of the units that I have seen in the past like this, the red LED would describe the battery voltage being too low to safely power the unit (i.e. battery be dead). Generally a couple of minutes charge will bring it up to a safe working value. However, after 30 minutes this certainly should have been enough. On one of my motorola units, the battery has expanded a couple of millimeters as it starts to dissociate. It may be worth you checking to see whether the battery in your universal has distorted in any way.
Hmm the red light comes on mine all the time.
It just means the battery is low and the unit is charging. .
It should turn green when the battery is at or near optimum charge.
no....thats not the red, charging is orangy when i say red i mean PROPER red. battery is not distorted, and to the best of my knowledge the unit had a good charge, im pretty sure it must have been some kind of hardware short, and am going to call orange as soon as im back in the country.
dosent explain though why when i whacked it it started working again. the whack instantly made the light go out :wink:
i did a battery rundown test as soon as i got the unit, and posted the results on the forum, if the cut off was not working, i would have ended up with a red light then.
i dont have the manual with me now, but is there any documentation on the red light?
Found this site which had an online manual:
http://www.rich-michael.com/pdf/User Manuals/050802_Universal_Generic_Manual_English_CDL.pdf
What does the phone say in the Power Tab?
A really useful extract:
13 Notification LED Bi-color LED on the right side: Green and Orange
for GSM/WCDMA standby, SMS message, GSM/
WCDMA network status, notification, battery charging
status.
Bi-color LED on the left side: Blue andGreen for
Bluetooth system notification of powered-up and
ready to transmit radio frequency signal, and Wi-Fi
status.
Couldn't find anything else on the LEDs

Sorry to drag up this old post.
My friend dropped my phone (Orange SPV C500) a few days ago on to a tiled floor. The phone didn't appear to be broken or faulty at all at the time. I even managed to use TomTom navigator to go to the airport, but for some reason when I looked at it before I went to sleep, the phone was off. I assumed the battery had gone (even though it should have lasted at least another day). I tried to plug in the mains charger, but the LED showed a red light. I left it plugged in while I slept, but it was the same in the morning. The phone won't power on at all. I've read that this normally happens on a flat battery, but I am pretty sure it still had juice for another day.
I brought a new battery, but to no avail, the phone still shows the red light when plugged into the mains. No light at all when plugged via USB to my computer. The phone won't power on at all.
It must have broke something when it was dropped. But I'm confused as to why it took a few hours to take any effect.
I also notice that even without the battery in the phone, the LED will still light up as red when plugged in to the mains.
I've tried whacking the phone now, but nothing. Anyone have any idea whether it can be fixed?

this is damn scary! Every day more people add on to the "my univ's gone dead after a small drop" community :?
When my univ was brand new, a friend of mine dropped it from a coffee bar table 3 feet high, and i still heave a sigh! Cant believe nothing happened...!
But one thing i guess we all know, its a "drop" away to kiss our device good bye :roll:
hope you get it back up and running m8! look around the forums, there are lots of breakdown-solutions threads...
cheers,

nice work afhstingray
do you think it was a baterry problem.
i have often used my battery till tit just ran out, from what i read in the post it seems to be a bad practice. anyway to turn off the phone
i doubt it was a battery problem as i've been using it until now without problems. (i didnt get a replacement as soon as i got back cos im waiting for this unit to get a bit scruffy before i get it replaced)
i had this once on my c500 as well, but taking out the battery for an hour did the trick. so i dont think the problem is related.
i've dropped my universal quite a few times already and im happy to say other than a few annoying dings on the metal plate with the orange logo, its working fine. and 2 of the drops were pretty bad ones too, i thought for sure the screen would die or crack. guess i got lucky and it hit the floor at an angle not too critical
total stab in the dark but maybe a broken connection on charging circuit? that could be why phone was ok then battery died and its now unable to charge?

wouldnt it have worked if it was plugged into the AC then?
Well my Exec was dropped onto concrete at the petrol station whilst I was trying to sort out TomTom and fill up my Yamaha R6 bike at the same time :roll:
No problems, just a couple of case marks.
I guess multitasking should be left to the ladies and computers :lol:

Hermes battery drains, Hermes won't charge, get brand new battery, still the same :O

Hello,
I'm sure my Hermes is not dead, I'm just having ridicious battery problems.
My battery completely drained out, I saw the screen fade out and kind of "die" as it happened. I then couldn't even charge the Hermes up, so it seems the battery just ran out of juice period. I googled around and it seemed the only way to revive the battery again is doing some complicated wiry thing with alkaline batteries.
But instead of that I just bought a new replacement battery. But it still won't charge! Does this mean my Hermes actually did die? The battery WAS extremely low so I'm certain that it was the battery. The phone can't just die like that.
Thank you so much for your help. N.B. the phone LED won't even give a red light when plugged in without battery in. I hope that's not a bad sign...
Hey there just a guess but I had a simular problem in the past and it seemed to be due to a defective camera part draining power. Only way I was able to fix it was to remove the camera part and then put it back together.
If the red LED doesn't come on when you connect to the power without the battery then your Hermes is dead, good only for parts.... If the LED does light up, connect the battery and see if it turns amber(orangey) that means its charging.
It could be the internal fuse blew. Might be replaceable but could be costly....
Yes, after reading that other people could usually still see a red LED without the battery, I gave up.
Sigh...well at least I got to see my Hermes die...the screen gradually fading away in front of me....sniff.... I will miss it dearly.
- - -
But life moves on and hey hey hey I'm the proud owner of a new Blackstone! I just wasn't ready to upgrade yet...I wanted to wait until a capacitive screened successor to the Touch HD came out...sigh
But I suppose deaths of family and friends don't happen when you're ready for them
Goodbye my Hermes

Dear eyupwolf, I have similar problems.
Camera just works some times, but after that it can not be initialised again and drains my battery out. So I don't use it anyway (since 99% times tried it didn't work). If I do, I have to reset Hermes many times to set things up.
Can you describe the procedure how you fixed (removed) that problem?
Thank you,

battery wont charge
I got the same problems with the Hermes 200. I tired the 3 AAA battries in serial connection but it didn't help.
I even tried to cool the battery for 30 mins in the freezer (an old trick to squeeze the last little bit from the battery) the phone turned on for about 10 seconds but the os never loaded up. the phone shows red when connected to usb without a battery but led turns off when battery is insterted.
I ordered a battery on ebay, but until it arrives does anyone have any other suggestions?
thanks

HTC elf doesn't start

Hello i have a htc elf0100, and suddenly he doesn't charge anymore nore start. It's completely dead, i already tried a new battery and i even charged the battery with a battery charger. I have measured the contacts of the phone when is connected to a charger and i have 4,7V wich may indicate that the power of the phone is ok. But in fact it doesn't power on. Does anybody know what might be the problem
Mainboard
Is it possible to buy a mainboard for the htc elf0100, and if so where can i buy it and how much will it cost?
Have you had any further luck with this problem?
I have a bought a Touch which appears to be suffering the same problem.
same problem here...
are any of you guys repairing these phones? I would'nt mind having a crack at it.

I tried repairing mine but no luck. There doesn't seem to be anything wrong inside it. Actually I had just finished refurbishing mine and for 2 days I was admiring its brand new white covers... Then, all of a sudden, the mobile turned off and doesn't respond to on/off,resets,chargers ever since. I am also guessing that my CPU must have been destroyed... :-(
I solve this problem whit the rework station, you need to heat the board, like 2 minutes in 400 Celsius, tried to don`t burn the conectors and the stikers.
Yesterday, after 2 months, it accepted the chrarger (led on) for... 1 second and then it started booting (for 5 seconds) but died again...
Wow! It responded again! This time it turned on and stayed on in bootloader! So I flashed it, and it WORKS!
So my tip is: every time you try to turn it on, always try in bootloader mode. So if it turns on, at least you will be able to do something!
Hi papajohn
how did you get it to turn-on again?
mine's dead no power response at all, completely dead, no tricolor, no white screen, no response to hard reset, can't enter bootloader, no orange led indicator when plug into power supply.

Battery or Mobo, opinion please!!

Replaced the LCD full screen assembly on my LG G2, all went smooth following a YT video couldn't really have gone wrong,
Switched phone on and battery displayed 0% for several minutes, eventually getting to 2% when I turned it on, all was still OK, however it dropped to 0% within a few minutes even while still plugged in,
Then it was completely dead, no charge light and couldn't turn on,
Removed all of the components again from inside of phone and rechecked all of the connections, again all OK, this time it cam on again!! 0% charging, so I left it charging waiting as long as poss, 45% it was at when I checked but left it while I was sleeping,
Woke up this morning to phone completely dead, cant power on and no charge light showing
Am I wasting my time buying a new battery? could this be another component? LCD?
Appreciate any help,
Thanks
Lee
have now disassembled and re-assembled a further twice and now it does not power on at all
no red flashing light and nothing on display
I've got a similar problem. Did you find out anything? Bought a replacement screen from ebay, and was really confident I could do this, since I earlier replaced the usb charging port with no issues. Of course the battery was discharged completely before this, but I charged the phone and it worked a week ago (which resulted in an annoying alarm that I was unable to shut off because of the broken screen). So after replacing the screen, I plugged it in and turned it on before putting on the back cover. At first it vibrated and I could see the backlight turning on. Then I could see the red led, and thought it was charging, but then the led started to cycle between different colors. I was not able to get a picture on the screen. I then plugged it out and put on the back cover, in case that was needed (didn't seem so from the yt video I used). After that, nothing. Not even a LED. And the phone didn't get any hot like it does when charging/working. It did somewhat get a bit hot the first time.
My first suspect was the battery. It did take some wiggling and force/heat to remove it‚ and it did kind of bend at the edges, but not very much. Any ideas?

Help! Battery drained, phone won't turn on, battery charging icon flashes on and off?

My phone had been working perfectly fine, as well as charging perfectly fine. Recently, I accidentally let it drop to 0%, which I don't usually do. I went to plug it into the same wall outlet as always, but instead of the usual charge process, the battery icon with the lightning bolt in the middle simply flashes on the screen and then turns off, which happens over and over again.
It should be noted as well that about 3 weeks ago my phone get fairly wet. After that incident, I turned it off till it dried, powered it up, and everything appeared to be totally ok. No problems since then until this.
Other facts:
-I can safely get into the recovery menu (power + vol down), which is stable, but any menu selections result in the Motorola splash screen for a quick second and then the phone powering down.
-The computer will recognize the connection to the phone.
Attempts to resolve:
-New cable, new usb hub, new wall outlet
-Trickle charge from the computer (same flashing)
-Phone in rice to remove moisture
-Toothbrush cleaning of Micro-usb port (suggestion from another thread)
I'm pulling my hair out, and I am considering prying off the back and replacing the battery. I have searched other threads, but have seen various solutions none of which worked for me. If anybody has any idea how I can fix this please help!!!
Thanks in advance.
Unfortunately most probably is the hardware problem. I had similar issue with razr. Splashed it on the beach, quickly washed with tap water, dryed it and for couple of days like nothing happened. Then suddenly digizer stopped working. It was motherboard. Luckily one xda member donated me the same phone with broken screen so I replaced motherboard by myself.

Thanks for the suggestion. Well, I got it back working again, by charging it for 5 hours straight and then not charging it for an hour. Now it appears to be functioning alright, with the exception that it once went from 40% bat to 15% to 0% in a matter of seconds and I had to repeat the procedure to get it back on. I have another turbo with a broken digi that I could cannibalize but I have no idea what to replace... the battery? Bizarre issue, but I guess that comes with the territory of water damage.
Maybe some part is still wet. If another Turbo has only broken screen, then is probably the easiest solution to take screen from the (ex)wet and put to another one. You just have to have proper screwdriver.
Replaced battery now Droid turbo flashing when I charge?
