I have a strange issue related to kenzo(rn3). My battery was swollen. So got rid of it. But when I went to buy a new battery the touch stopped working. So I tried to get it repaired in local shops bcz mi center were charging 4k. But local guys couldn't fix it. The issue was may be of motherboard. After some days I again restarted(with charger only, didn't bought battery) as usual, this time the touch worked with no problem even after restarts. So I bought the battery and was using the phone. But the battery backup was not good bcz of miui 9.5. So I searched for a good sot rom. I downgraded to miui 7.6.3. No imei issue happened but touch again is unresponsive. I tried installing miui 9.5 with no luck. I think the issue is on the software part. I clean flash installed roms every time by miflash. Help anyone. Please.
I think your problem is a unique case, I can't relate. However, I DO get those touchscreen problems. I get that very-very-rarely. A forced restart by holding the power fixes it.
I recently changed to MIUI 9.5.6.0, haven't gotten any of it yet. I previously came from Official Nougat LOS, and then changed to xiaomi.eu ROM before finally change to this genuine stock MIUI. I got that issue in both LOS and xiaomi.eu.
Restarting couldn't help me.

Maybe there is some hardware issue. But why after flashing the stock rom it doesn't responding.
Do you use original touch? Or focaltech?
If you change some hardware i recommend to reinstall rom and kernel (the rom with fastboot).
Equally the battery (i think) may not generate this issue.
Oh! I remember in other device my charger freeze my phone... But its very rare... What charger do you use commonly?

I once got the touch repaired at the service center. It was 2 years ago. I have installed rom in edl mode. When the touch again worked on its own, there was only charger connected to it. The issue may not be with the charger. May be I should try with more local repair shops.
Use aida or other software to see touch model and if you have focaltech i recommend to you agni kernel 13. In Aroma do you set focaltech option.
If you have original touch the problem may be other...

i dont know... do you can ask to developer to only focaltech compilation... equally i dont know... I believed that Focaltech was compatible in recovery but not in system (i never have Focaltech and im not sure if your problem is it.)
Your problem is very rare... but make me remember similar problems in notebooks with touchpad and steel case...
in some notebooks if the case is steel and you touch the case, the touchpad not work but if you dont touch the case work perfect (yeah... this is rare but in my opinion is "ground" (talking about electricity) problem.)
i dont have more ideas, your problem is very strange and probably hardware.
Good luck bro

Thanks for the suggestions. May be its more hardware related. It was just a luck when the touch worked on its own. May be some shorting is there. One more point I want to add is that when the battery was swollen the display bent too. Some impact may be on the motherboard too. The local repair guys confirmed touch is good. May be the motherboard is dying.
U.U
Remember: you can use keyboard and mouse USB if you need to use "Titanium Backup" or other app.
What's happened is most likely this. The swollen battery bent the mainboard's PCB and either cracked some solder joints or lifted a pad/broke a trace. Now you have bad, intermittent connection. You could probably reflow the joints using a hot air station but you wouldn't be here asking for help if you had the required tools. If it's a lifted pad under a big chip, that's simply too much work (anyone that can do that would ask for at least the cost of a new phone).

From what I have seen on the pcb, there is a probable smd part near the power ic. You correctly inferred that I don't have tools to fully inspect/try blowing hot air. But I did tried blowing hot air using a hair dryer. I also do suspect that repair shops I went didn't tried that. Thanks for the suggestions.

Some more questions. What is a lifted pad?
Some more insights are, Once the touch was worked on its own, it worked pretty well. I then purchased the battery and installed. Used the phone for 2 days. And then I downgraded and touch went unresponsive. Could it be really a hw issue? Well I too think that it's a hw issue. But couldn't help myself question this. Maybe there is some irregular voltage being supplied. The touch might now be accustomed to the power provided by the old battery?
Some devices can work with charger without battery (notebooks, some tablets and phones, i dont know if all)
Try with this to test if work fine all... If yes i recommend you test your battery voltage/ampers.

When the touch worked on its own, it was only without battery because i dumped the old one and didn't bought new because the touch wasn't working. When the touch worked it was connected to the charger only. Battery is giving output of 3-4 Volts.

The voltage when checked fluctuated bw 3 to 4. The multi meter reading was not showing volts after decimal. I will check. Again with a more accurate multimeter in a while.
The battery model is bm46 though. And what does 3.85 depict on the battery?
what i dont know (again)...
4.4v charger voltage (after pass of diode and otherf circuit?)
3.85v to output? (phone use)
if yes your multimeter reading is good (3v and 4v).
i try to help you with ideas but is very rare this.

Well, modern electronics use lead free solder with a melting point that's somewhere around 250°c. Basically you need an extra 100 degrees to reflow and I doubt your hair dryer can go as high as that. It's only good enough to melt adhesive.

A lifted pad is when the copper contact is ripped off the board as a result of excessive flexing or overheat, usually under a big IC. This ends up damaging or cutting the trace leading to that pad. To fix that, you can only micro solder a very thin insulated wire under a microscope. You may need to desolder the component resting on that pad first to fix the pcb.
Certainly, a component might operate just a bit out of specs but since you don't have schematics, you'd have to do hours of guess work, assuming you already know how. I suppose you could randomly replace likely culprits and hope for the best but... Well, let's say it's far from ideal.

Hi all !
Yes my hd2 freezes a LOT when it gets very hot while charging and also when i start it sometimes it vibrates 6 times and freezes without loading the system so if ther' any solution for that ? i installed the last GTX rom and also i did test the latest stock T-mobile rom with the radio 2.14.50.04 nothing changes it's freezing a lot.
Thanks in advance.
two possibilities:
1. one of you battery connectors might be bent (I've seen few threads on this issue here on xda)
2. faulty mainboard (been there) - if you Leo is under warranty, restore it to stock settings and send for repair
in the meantime you might consider using Battclock for battery temperature monitoring, once it gets to "freeze zone" switch your Leo off for a while or - if desperate enough - put it in the refrigirator (5 minutes should be sufficient)

Thanks for your reply, i think the problem is coming from the copper pins as you said ( or connectors as you've said ), when i touch them the phone boots good, but it doesn't fix it i must always touch them and wait that the phones boots so, how can i fix thoses pins once and for all ?
Some users here reported freezings due to a bad Radio and ROM combination. Maybe you should downgrade to a different Radio and choose another (stock?) ROM?!

Thanks in advance
We've had issues similar with the work HD2and it was resolved by replacing the battery.
How or why this came about was beyond me, but it must have been due to some of the idiots we employ playing about and not showing due care with the phone, so try a different battery, they are cheap enough

Ok i'll buy a new one and i'll try
between i saw a strange thing on the battery ( the battery is deformed at the top a small part ), the battery costs here more than 20$ so it's not that cheap here, but i'll buy it i hope it will fix the problem.
But tell me after buying your new battery the problem is fixed for good? no more overheating?
Thank you man for your anwser.
UP !
I did buy a new battyr today, no chan ges the problem is always the same....
so i very very sad after my last try, i must say now my hd2 is dead and with no warranty i can say Fu*k lol.
Thanks everyone for your help and i will never buy htc phones !
What actually happen? I would keep trying and if it won't turn on anymore. I would still try to claim warranty by htc. Maybe they are not gonna repare it to difficult. So they can't check for hspl. And then they maybe send you a new phone. As far as I know it doesn't cost your anything when they detect hspl. They just don't repair it.
Hi all,
I had to replace the power button flex board of my i9100, but I made a mistake when soldering, and something shorted and a SMD in the board exploded with a *BANG* and went flying like a bright shooting star. Then came the smell of fried electronics, oh boy, that was horrible! Strangely, I couldn't locate which SMD component exploded, the boards looks fine, even if carefully examined with a 10x magnifier.
I thought the board was completely destroyed. But I fixed the power flex cable soldering, assembled the phone, connected it to the USB charger, and guess what?? The recovery menu appeared, some message appeared and quickly disappeared, and the phone booted normally! Everythting worked: network, wifi, bluetooth, camera, etc. However, the power button didn't work anymore, even now it's properly soldered.
I removed the battery to turn off the phone, but now it doesn't turn on with the button. If I plug it to USB, now it shows the charging battery screen, animated and all, but I can't turn on the phone anymore!
So I ask: does anyone know which SMD components take part in turning the phone on by pressing the power button? I can't find this info in the service manual, but I'm sure it's just a matter of replacing a burnt SMD resistor, capacitor or inductor, since the phone works, I saw it working!
So, does anyone have any info for me, or at least a detailed diagram of the circuitry, so I can find my way into that?
Thank you all in advance!!!

Hola Eduardo,
you probably used a too high temperature in the soldering iron.
Google for "56542824-Samsung-GT-i9100-service-manual.pdf" and you will find a good service manual that will guide you on a series of problem.
I doubt that there's a procedure for your specific problem, but you may be able to know what SMD you have to replace.
I wish you luck, and next time make sure that the temperature is low (and eventually use a solder paste!)

Thanks for your reply, robdpi!
The soldering iron temperature was ok, I used a 12W Weller micro soldering iron, temperature was not more than 550F / 300C, and I never leave the iron on the work for more than 3 continuous seconds. The problem was a short between two of the 3 pins in the connector. I noticed it only after the accident occurred, testing with my multimeter.
About the service manual, this is the one I have, and the testing procedures (voltages, frequencies) are all OK when plugged to the USB, but they all fail when I try to turn it on with the power button. And you're right, there's no procedure in the manual regarding this specific problem.
Anyway, I will keep trying, thanks again,
Eduardo
Well, after almost an year, I fixed the phone! I'll write about the solution here, to serve as a reference to anyone who needs help.
I managed to find the electrical schematics of the whole phone. With the information given in it, I noticed the connection between the positive battery pin and the flex power button connector was interrupted. Probably the short circuit I did overheated and blew some thin trace on the PCB and it kind of exploded. So I soldered a thin wire between the battery connector and the power button to replace the lost connection, and the phone is now working again! If anyone needs the schematics, just PM me and I will send it over.
But now, I'm back to another issue the phone already had, even before I did the short circuit: the screen shows horizontal lines, blurring the image. It started after I replaced a cracked screen. Does anyone have any idea if it's software or hardware related? May it be a driver issue? I'm from Brazil, and the screen came from Korea (bought at eBay). Should a korean screen work in my phone? Is it possible to confirm or not if it's hardware or software related?
Any help will be great, thanks in advance!

I attached 8 pictures showing how the thing looks like. Please note the banding can't be seen on black background, and it's only horizontal. I used red arrows to show the banding. Vertical and curve artifacts are distortions caused by the camera.
If you pay attention to the file names (which have the time each picture was taken) it's possible to see how the thing gets worse with time. In the last pictures, screen goes completely unreadable, it degrades to an almost uniform bluish white.
I already tried flashing a custom kernel as suggested on another thread, but it didn't help. Already tried stock 4.0.4, that didn't work also.
Thanks a lot for any help.

You mean you tried the screen on two motherboards, and it shows the same problem on both? Could you please tell the country of origin of your motherboards and screen? I suspect it may be a hardware incompatibility issue.
In other words: motherboards sold in country X may not "talk" correctly to screens from country Y. My i9100 is from Brazil, but the screen came from a Korean seller at eBay.
By the way, does anyone know if the official firmwares come with low level hardware drivers? Is it possible to "transplant" the video driver from an asian firmware, to a south america firmware, for example?
I know about android phones which changed the wi-fi chip during their life cicle and this transplant used to be made, and worked. I would like to try the same for video.
Thanks!

I have only one battery, so can't swap to test. But could you explain how could the battery cause this problem?
I just measured the battery voltage with a digital multimeter, and it's 4.15 V, fully charged. This is almost a half volt above the 3.7 V it should be. Do you think this may be the cause for all the problem?
Many tthanks!
Yeah, screen might not getting enough juice.

I did another test: measured the battery voltage with the phone turned on, to check the voltage drop caused by phone load, but it seemed normal. With phone on, battery measured 3.8V approximately, which is a little less than the 4.15V I got without load. The battery indicator shows 75% battery charge. It looks like the battery is behaving well under load.
Anyway, I will try another battery as soon as I can.
Thanks again,
Eduardo
Well, I did test with another battery and the problem persists. Should I give up and consider it's really a screen hardware problem?
Thanks,
Eduardo
My guess was on the battery, I guess I'll take the screen problem then.
You should have it checked it out with a tech guy.
Sent from the little guy
Well, I think I went as far as I could. I replaced all 20 tiny SMD components from the display flex PCB with the ones from the old display, which cracked.
But it didn't work, the problem remains. Now I think the problem lies in the AMOLED screen itself, or perhaps in the main phone board. Who knows if the main board is sending dirty electrical signals to the display?
Anyway, I think I will just sell the phone the way it is, I can't afford spending even more money on this phone.
Thanks for the help, gastonw!

hmm i don't think is my router problem as my other devices can connect to wifi. It is not a connection issue.The problem is that i cannot even turn on the wifi on my S2. it keep saying "Turning Wi-Fi on"

Hi, im experiencing exactly the same issue. I was using RR for some time. Version 3.0.9 for the last couple of weeks and had no problem. Yesterday picked up the phone and tried to turn on wifi and the slider was kinda greyed out. Since then tried everything. Flash different kernels, whole ROMs, old, new, no difference. Whipes, restarts, leave the battery out for some time. Nothing. Tried to find answer, but also no luck. I am worried, that it is hardware. Can anyone bring some light to this issue? Thanks.
Edit: Problem found. Took the phone apart and to my surprise - the small button battery leaked and the acid f..up one resistor and its surundigs, that is responsible for wifi. So now i will try to repair it. Have resistors, but dont have enough patience..... I will share results as soon as i have them.

Wow. so it a hardware problem? Hmmm hope to hear from you soon!
So finally problem fixed. Solder-out the BAT500 which was ruined anyway a took with it the resistors. Change resistor R205 and replaced it with another one from a old PC motherboard. Couldnt find one exactly the same size, but found two aproximatelly twice the size with the right specs. The soldering was the tricky part. Fist tried it just with magnifying glass, but that was not enough. So I ask a friend for help and got a microscope. Since then the job was much easier. But still took a lot of patience. Taking the parts out was pretty easy. After that I cleaned the rest of the acid and saw the real damage done by it. Battery BAT500 leaked out pretty bad and took with resistor R205, which was completely dissolved. One connecting pin was quite OK, but the other ano was gone as well. So I cleaned out everything. Took the new resistor and tried to solder it in place. In the process I screwed-up and burnd it. Good thing I had 2 The other one was little bigger and wouldnt fit in the original place. So I solder one end to the existing connection point and the other side directly to pin on the wifi chip with the use of a very thin wire from headphone cable. Not the cleanest job ive ever done, but its working. Checked for shorts, measured the impendaces and tried it.
Im very pleased, that its working. Sofar I couldnt find replacement for BAT500, so just left it without it. Not a biggie.
It took me about 2 hours of work (with many mistakes and resistors jumping all around the table ) But finally done. Hope it stays that way for a long time.
Wifi is working like a charm and to my supprise, I think that the phone is not heating up as much as before. But if Samsung would have put better quality battery inside, this would never happend. But I guess thats on purpose, because than nobody would have to buy a new things Right? Every piece of technology nowdays have some king of component that have only one purpose - to ..... things up !!!

So finally problem fixed. Solder-out the BAT500 which was ruined anyway a took with it the resistors. Change resistor R205 and replaced it with another one from a old PC motherboard. Couldnt find one exactly the same size, but found two aproximatelly twice the size with the right specs. The soldering was the tricky part. Fist tried it just with magnifying glass, but that was not enough. So I ask a friend for help and got a microscope. Since then the job was much easier. But still took a lot of patience. Taking the parts out was pretty easy. After that I cleaned the rest of the acid and saw the real damage done by it. Battery BAT500 leaked out pretty bad and took with resistor R205, which was completely dissolved. One connecting pin was quite OK, but the other ano was gone as well. So I cleaned out everything. Took the new resistor and tried to solder it in place. In the process I screwed-up and burnd it. Good thing I had 2 The other one was little bigger and wouldnt fit in the original place. So I solder one end to the existing connection point and the other side directly to pin on the wifi chip with the use of a very thin wire from headphone cable. Not the cleanest job ive ever done, but its working. Checked for shorts, measured the impendaces and tried it.
Im very pleased, that its working. Sofar I couldnt find replacement for BAT500, so just left it without it. Not a biggie.
It took me about 2 hours of work (with many mistakes and resistors jumping all around the table ) But finally done. Hope it stays that way for a long time.
Wifi is working like a charm and to my supprise, I think that the phone is not heating up as much as before. But if Samsung would have put better quality battery inside, this would never happend. But I guess thats on purpose, because than nobody would have to buy a new things Right? Every piece of technology nowdays have some king of component that have only one purpose - to ..... things up !!!

Hi,
Can you please help me specs of the resistor, I mean R205 is of how many ohms ?
Thanks
You need the Samsung I9100 service manual, which has been posted here before. It has full parts lists & 'tutorials' of most of the common fixes their techs do. Try a Google or XDA search (You're could wait a long time for a reply from the person whose post you're responding to given they made it 9 months ago).

I have manual but it does not specifies value of the resistor.
Attached is the screenshot of the manual, please let me know if you can make out the value of the resistor

I just fixed today my galaxy S2 I9100. It had the same issue BAT500 leaking acid. (wifi not working)
Since you ask for R205 value. I'm sorry didn’t saw your post earlier. But maybe you can measure it's value from R204, R206, R207 since in your own screenshot it seems they all have the same value.
Some people are using 20kohm smd resistor.
I'm also interested in replacing BAT500. I measured 1.2V in open circuit and 1.0V in closed circuit, with positive towards mainboard.
I will try to find a replacement battery.

Hello.
So to make a veeeery long story short, the phone leaked water in a lake at about 0.5 meters depth after a minute or two with flaps definitely closed (checked 5-10 times before submersion). The screen then flickered and died.
Phone gets sent away to a service center, tested and results unsurprisingly say its watertight so must be user fault. Sony and service provider refuse to help me in any way to fix the broken phone, so basically they say i have to pay it as normal (it was 4 weeks old at time of damage).
I received the phone back after countless phone calls to sony and service provider trying to get them to take responsibility, especially sony, but to no avail.
So now im trying to fix it myself. I took the phone apart, and the screen connector at the bottom was fried as expected. I bought a new screen and flex connector cable but still my screen wont show. The touchscreen works perfect, and so does the phone. When i connect it to my tv via MHL it works flawlessly. Every function including the new touchscreen works perfect, just that the screen is black on the device.
Am i missing something?? I really want to get this working so i can say IN YOUR FACE to this stupid company SONY. Im thinking the only thing it could be now is some faulty component on the mainboard regarding screen output, seems strange though that everything works perfect via MHL, especially the touchscreen.
Anybody have any ideas? Would be greatly appreciated if anyone can share similar experiences!
Cheers, Vincent from Sweden.

Hello.
The phone has booted ever since it got water damaged, even with the bad screen. Yes the touch panel works perfect but no display, and i can see and use everything on the phonebon my tv via mhl cable. I even updated firmware whilst using mhl to see if it would help but still no picture on the device.
I have replaced the touch screen and the flex ribbon cable that connects screen to mainboard. I have also removed mainboard and cleaned it with 95% alcohol incase some water or dirt causing a short circuit somewhere.
The mainboard looks fine, and everything works apart from the visual screen. Nothing is overheating. Im really baffled as to what could be wrong, but it surely must be something on the mainboard?

I got same issue on Galaxy S4 but that wasn't water proof so this type of damage was normal for it.
have u tried ur display on another board?
- as Sony said it was user fault... after phone get wet have u tried to dry it with heat?
+ as i read the warranty agreements when u open phone by urself or others (non official center) it will void the warranty.
anyway If ur display not working with another board so thr is problem in display panel and not anything on board.
Please Inform me if u got any info or result of this damage
Thanks

Yes the phone is thoroughly dried out. I only opened the phone after i had received it back from sony service. They said it wasnt covered by warranty because it was water damaged and was caused by the user (even though both water indicators behind the 2 flaps are still white and not been exposed to water), and they said that they never repair water damaged phones.
Thats why i decided to open it and try to fix it myself, i had nothing (more) to lose!
I havent tried the new display on another board, thats exactly what i want to do but cant get hold of a new board. I've even been taking apart previous smartphones to see if the display can be connected to it somehow just so i can confirm it works. But the probability is that it does work, as the first "broken" screen worked in the same way as this one, touchscreen fine but no display. Thats why i changed the flex cable also, i thought it must be that when the mainboard seems to be doing everything else perfectly.
Does the problem have to be in one of those 3 components? Screen, flex cable, mainboard, or have i missed something?
Thanks

Yes, it should be those factors. From what you have stated, its most probably the connector on the main board. Before you make more purchases, try to take it to a shop and ask them to test the screen on another phone, so you can see if its the screen or not. It MIGHT be a faulty flex cable that you just purchased, hopefully, since its the cheaper solution. I actually bought one in ebay that was water damaged, changed the screen, middle frame and flex cable, and have a brand new refurbished Z2, good for me the main board was intact. I would take the board out, wash it with 95% alcohol again with a soft toothbrush to brush impurities off the connector piece. Then spray it a little with electrical spray and leave it in rice to thoroughly dry out overnight and try all the connections again. Look through the main board with a magnifying glass and see if anything obvious burned out, the smallest connection can cause problems.
If all fails, then take it to a shop to test the screen or the main board, hopefully they are friendly enough to do it.
Good luck buddy. :good:

Sounds like good advice elbello
Good to know that you have managed to fix a water damaged Z2 using the same mainboard, hopefully i can have the same luck.
So you think it could be the flex cable? Are they known to break easily?
I have already cleaned the board twice with alcohol, maybe using electrical spray might help, and i will check it with a magnifying glass aswell.
Hopefully i can find a shop that will test the screen for me, but this is Sweden, the place where no favours are done, and where everything has to be sent away and fixed by professionals!
Thanks for the replys guys
I have just checked the whole mainboard with a magnifier, and found no oxidation anywhere. I found quite a bit of dirt in some places, and i have once again cleaned the screen connector with 95% alcohol and also the other side of the board behind the screen connector. I dont have any electrical spray at this time so cant test with that.
Another thing i have realised is that there is visual damage to two contact points that are located at the bottom of the phone, very close to where the flex cable connects to the lcd screen. What are these two contacts for, and could they be causing the problem? I will attach an image of them.
Thanks.

From that picture, I dont think that affects the screen at all. Bad thing is you cant try the two pieces you bought with another board so you can narrow the problem down.
I doubt the electrical spray will make wonders, it just good to clean dirt and make the contacts react better after oxidation, but if you state they are clean...
Think your only options is to consider it a loss, sell it in ebay for parts and stuff, or try getting a new flex and see if it was that, but if it wasnt, its like throwing money away. I would say the same for the screen, but those go for $100+ easily.

Yea i was thinking about selling it for parts, but its not really worth much without a working mainboard. I will probably just keep it and wait till i can get hold of a new board. How much do you think a new board would cost? I cant find one anywhere at the moment when searching on ebay/google.
Wish i had access to a working board for testing

I'm now in the exact same position.
Water damaged, Touchscreen is still working I can enter recovery any press stuff but no display only shows black.
Had my screen replaced in a shop here but same problem prevails.
They told me to replace Mainboard 3500 THB.
But they didnt have one right then.
He could fix it?

Thinking of buying a used z2 with intermittent touchscreen issues. It works but seems to be intermittent it either takes multiple taps to work or it goes mad like your pressing the keys could this be down to water damage or possibly just a software issue and need re-flashing a ftf by clean install it's a totally stock z2 in mint condition for £50

Ghost touches are a digitizer problem right?

Hi, I have a problem with a Honor 10.
Since August it started to restart randomly, I just replaced the battery and I just did two factory reset but the problem continues to manifest even in the configuration screen.
I would exclude the faulty power button, since before rebooting it usually froze on the activity I was performing.
Any ideas?
Thank you!
Test power button with ohm meter.
It was doing this after the reset with just it's factory load? No 3rd party apps loaded?
Try reflashing firmware.
Maybe be a mobo failure.

I really don't think is the power button because it reboot even in idle on the table, and i saw that if i put it on charge it reboot instantly.
I have this problem even in the configuration screens after the factory reset, indeed i've must configured two or three times because of that.
I'll try to reflash the firmware, then i'll wait for a new battery i ordered a month ago.
If it will be still broken i guess is a mobo failure.
I have a question: i didn't flashed a smartphone before, and i was asking myself if this reboot problem can mess up with flashing, bricking the phone. Can it be possible?

Yeah if it interrupts the flash that won't end well...
If you can return it, do so... otherwise...
Before you go flashing nuts try to determine if it's a hardware issue. Check ribbon cable connectors... and that switch.
Firmware shouldn't become corrupted unless there's a flash memory failure or it was a bad flash to begin with.
Does it not do this is safe mode? 3rd party app if so.
If it does it when in the boot menu it's likely hardware.
If so it may be just a failed battery. Try with charger connected to see if this alters the behavior.
If you don't feel comfortable repairing it, let a good tech do it for you. I always remember my first mechanical alarm clock disassembly... it didn't go well

It reboots even in safe mode!
It would seem a hardware problem, possible that I bought a new battery already damaged?
It’s been a few hours since it works good after charging it to 100%, it seems that it starts to reboot towards 50%.
I wanted to flash it also because before doing the factory reset, it automatically installed some "stock" apps by itself, I refer to some games that Honor automatically installs at each factory reset, every time I uninstalled them, after some restart they reinstalled themselves.
It was a weird issue but looks like fixed with the factory reset, so now i only have the reboot issue.
I am so desperate that I would like to try the battery of my Honor 10 (the one with problems is that of my girlfriend), I would not buy another battery since I have to be delivered the one I ordered from a month.
It may be the battery, they can fail at any time.
It's rare for new ones to fail but it happens.
Use a firewall to block auto updates or installs.
Karma Firewall works well but its valuable logging feature doesn't work on Android 10 and higher, but it still will block apps.
Update: I just bought another battery and the problem persist.
Now im sure is not the battery so i will flash it very soon no matter what.
I have been having the same problem as you guys have since last Christmas (2020), when my phone was 18 months old.
I switched phone and gave the Honor 10 to my wife for Coin Master and the problem persisted.
However, two months ago the battery started to swell and surprisingly the problem went away completely for about a month. But as it swelled to the extent of pushing out the screen the problem returned a month ago.
Thinking it was possibly a battery/battery connection related issue, I changed to a new Pisen battery last night. Sadly, the rebooting continued but only for 2-3 times today.
So it is probably an issue with the board itself.

The battery failure may have damaged the mobo or perhaps it was preexisting.
Check ribbon connector pins for damage. Look around for visible solder cracks. Try pressing gently on the mobo with a pencil eraser with device powered on to try to find the area. Check ribbon cables too by gently moving them.
One of the most likely places for a failed solder joint are the BGA chipsets. The many solder pads are under the chipset, inaccessible.
Press gently on them to try and verify this. A hot air station (and skillset to use it) is the only way to repair this type of failure.
Any battery swelling is a failure, replace it asap.

As I said, battery has been replaced with a brand new one. Therefore the swelling issue is fixed.
Don't have the skill set to use a hot air gun or to solder so this is it for me.
Quite disappointed by the QC of Huawei as this was my first Huawei phone. I have been using Xiaomi since my first smartphone and never had an issue like this before.

Quite disappointed by the QC of Huawei as this was my first Huawei phone. I have been using Xiaomi since my first smartphone and never had an issue like this before.

My point was a mobo failure is generally a game over event.
I run strictly Samsung's as I like their UI and have become familiar with them. Of course in 2-3 years that could change if Samsung keeps dropping the ball.

I understand.
That said, Huawei did replace the MBs for out of warranty customers in mainland China as a good will gesture.
Too bad that policy did not extend outside of China.

Maybe see if they'll discount a mobo for you.
Not free but it might sweeten the deal.
Or write it off and move on.
All my Samsung's have been long lived with replacement batteries being the only repairs.
Another reason I like them.
In my case it was sort of dumb luck especially when choosing the first Note 10+. In this case they did live up to their hype.
The S4+ lasted over 5 years and still boots up.
I had the random reboots going on for weeks even at night, also bootloops sometimes .
I tried a lot of stuff but i got my phone going again for 2 weeks now without any reboots.
It might be just pure luck but this is what i did last time:
Did a complete reset of the Phone ( everything gone )
I changed simcard to other simslot (i think this made the difference, atleast for my phone)
No apps from Meta (You dont want any of their **** anyway )
ill keep you posted

Put on performance mode (might not be it, but details mather here, today is first day without performance mode, no issues so far)
No apps from Meta (again because details mather, might not be it, i had random reboots all the time, but when i was using instagram or it was still running in the background , it was real bad, You dont want any of their **** anyway )
ill keep you posted

Yay!
Meta is malware.
Hey guys, it seems that I solved the problem by bringing the phone to a Huawei service center, they performed an "operation on the motherboard".
Actually they changed the battery with an "original" one for 60€ (the one I had replaced cost 10€ ), then when the problem obviously came back they did the repair on the mobo at no extra cost.
I guess it went well.

Did you had any reboots after the motherboard change?
I got the same issue with my Honor 10. Tried every trick that I could think of, but nothing seems to help.
What I noticed, that sometimes when it restarts it does get very hot in the area near the camera. (not sure exactly what component it's there but it's something on the motherboard)
I'm thinking if it worth doing this motherboard change. (as it seems to be a design/component issue if there are so many that have this problem)

No, no reboot at all, but I noticed later that they rolled back to Android 8.0, so I’m thinking that they didn’t fix the motherboard, but they actually found a workaround by downgrading the OS.
I’m afraid to try to upgrade to Android 10.0 for this reason, I don’t even know if I can do it considering the new Huawei policy of flashing and stuff, but my girlfriend is ok with that so I let it go.
I can confirm that even now, on each task (TikTok scrolling for example), it gets very very hot in that point near the camera, my perfectly still working Honor 10 instead does it only on intensive use of the camera.
I hope this information can help you with your Honor 10, I suggest you go back to an older version of Android if possible just for troubleshooting.
If it persists, the motherboard is probably faulty and you need to replace it, I guess...

Thanks for the reply and downgrade suggestion! (worth a try)
