[Q] i9100 Wifi completely dead. SOLVED - Galaxy S II Q&A, Help & Troubleshooting

I've read a few posts here with similar problems but the solutions (if any) haven't worked for me.
My wifi started to switch off intermittently. The "switch" icon in Settings would move across to the "ON" position but would then move right back to "OFF". Then after several hours the wifi would magically work again. Now it has stopped working altogether. I tried going back to GB including wiping data and cache then went forward to JB 4.1.2. No luck. I even tried GS2ROMNuke in between and Siyah kernel. I'm now back where it all started with WanamLite Clean & Fast & Pure Stock Themed 4.1.2
I opened the phone and checked for internal battery leakage but there was only a tiny amount and that was still on the battery itself, none on the circuit board.
At this stage I have just about given up. Has anyone managed to recover from this situation?
Of course it happened just 3 months out of warranty

Hey bro, sorry to hear about your problem. Have you tried testing the Wi-fi after installing a new ROM without updating or changing the stock kernel?

I think I have... not 100% sure though. Might go back to stock and try again though. Such a PITA... I was going to upgrade to a Note 3 and pass this S2 on to a family member. :crying:

Success!
I'm sorry to resurrect a long dead thread.
I just wanted to let you know I finally fixed my wifi issue. The problem was (as in many cases) the battery near the wifi chip, leaking. Although I had previously opened the phone and cleaned the PCB with isopropyl alcohol, I hadn't noticed that the track between one of the resistors and the wifi chip, had been eroded. I scratched some of the covering off the track and tried to measure continuity to one side of the resistor but got an open circuit. After clumsily soldering a piece of fine wire from the resistor to the scratched piece of track, wifi was restored.
I really can't believe it. I had previously inspected the board close up and thought that no erosion had taken place. But now after taking some time (and some beer) I found the fault.
Some feedback for Samsung... you *****es! How can you fit such a weakness to, what was, your flagship phone? This issue has hit so many users. I have read many many posts here and on other forums complaining about wifi problems with the SGS 2. Unfortunately for me this fault occurred when I was a few weeks out of my 2 year warranty
This was not an easy soldering job. I am fairly good at fine soldering but attaching a wire to a SMD resistor so small was really difficult. It may come off in the future but at least I now what and where the fault is now.
Once again, sorry to resurrect the old thread.
FYI the resistor that was affected was the one that sits by itself at right angles to the other 4. Unfortunately it is nearest the battery.

[H] Phone thinks usb/ac is connected/~charging

**Please note, i have already searched this forum and found some similar threads as: charging paused, voltage too high, SGS2 charged all the time, Charging suspended. Voltage too high and Phone keeps charging after plugin off the charger but none of them had exactly my problems so i'll try to describe mine better here.**
Some background and possible cause first
I have been using Omega ROM @ 2.3.5 (yes it's old, but it doesn't matter) for more than 6 months now and i haven't had any problems with it, but a few weeks ago i decided to upgrade to ICS so i did a full backup with CWM and also backed up sdcard to pc. Did a full wipe, formatted sdcard and installed the AOKP ICS, hated the camera app, wiped everything again, installed normal ICS, it was looking ok but i needed my usual apps the second day so i decided to go back to my 2.3.5, restored backup, restored sdcard. I don't remember exactly if i had the phone plugged in before installing ICS or after going back to 2.3.5 but when i disconnected it, it showed that it was still connected and charging...
Please note that everything was ok before updating to ICS (which is one reason why i believe it's software related), i used the original mains charger / micro usb cables at home and i also used a cheap car charger but long before this started happening, and the last time i used the car charger was 2+ moths ago.
The thing is, i don't care if it things it's charging all the time, my problem is that when charging it keeps the cpu active, and even when setting it to 100 MHz the battery only lasts about 5-10 hours with low-moderate usage (see the screenshots of cpu spy, it is clear that the phone does not enter deep sleep while it "thinks" it's charging).
Symptoms
At first, it kept showing it was charging all the time, sometimes when reaching ~10% it went back to normal (YES, normal aka reporting as no plugged in and no charging (=discharging), so i don't think there's any short-circuit/something wrong with the usb connector (which i tried to clean up, as suggested, but the problem is still there) :
---
---
Then (and currently) after 1-2 mins of disconnecting charger/usb cable it stops the charging animation but *#*#4636#*#* and some battery app stats show that it's still plugged in but discharging (also it reports over-voltage, which is weird because when it is still charging it shows health:Good).
Also, if it goes back to normal (aka not charging and not plugged) and i connect the mains charger then disconnect and connect usb cable it will still see/think that the mains charger is still connected and i can't connect the mass storage to pc (the dialog never shows, because it still thinks it's connected to mains) and vice-versa, but the battery is charged no matter where it thinks it's connected.
Now the weird part, and the reason why i don't think it's hardware (aka usb pin short circuit or anything else stated in the other threads) if i remove the battery for long enough (something around 10-12 hours) over night, in the morning the phone would be completely normal (i was able to do this 2 times so far and both times the phone clock&date were resetted which makes me think the "connected" state is stored somewhere in a temporary memory powered by a small battery which keeps track of the time and alarms?; also if the time isn't resetted, the phone would still think it's connected (yes, even after removing the battery for some 8+ hours)), but the problem reappears if i connect charger/usb cable (something to note here, if i connect the cable and it's not plugged in, the problem doesn't start so this excludes micro usb connector problem).
---
And also, as in some other posts, while the phone is shut down it keeps showing the charging animation along with some warning high temperature? triangle:
Here is a screenshot of Battery monitor widget showing some weird voltage spikes, is it possible to reach 5V?
The wakelocks (from Better battery stats app):
Also, something that i've wondered if all S2s do, when i remove the battery and plug in the charger (of any kind) the phone shows a no battery image:
One other thing that might worth mentioning is that sometimes, just a few seconds after i lock the phone, the screen just lights up for a second then turns back off for a few times (2-5 times), but this might be just an app problem and it's not really currently bothering me.
Also i just noticed when posting the screenshots that the battery is always pretty hot, is 32 - 37*C too hot or is it ok?
Conclusion
Well, it's been 3 weeks since this problem has started because i updated to ICS and i still didn't fix it. My plan is to order an Usb jig from ebay, get everything back to stock and send it to warranty, but this will take some 2-3 weeks until i get the jig and another 2-3 until the guys fix/replace it so i'm posting here hoping for some suggestions from more experienced members or people that also had this problem, because i ran out of ideas to try here.
It's a very nicely thorough post, very detailed. I like it.
However, I believe your conclusion that it isn't a hardware issue with the port is a faulty one. I think 100% of the times I've seen issues like this it's an issue with the port that is resolved either by cleaning it, (which will likely only be a temporary solution) or replacing it. It's VERY likely they will do just that (replace the port) if you send it to service. If you can get it covered under warranty, do it. Otherwise the part will run you probably $15 or so, USD.
But the fact that the problem comes and goes away without physical actions and also the fact that everyone started getting this after upgrading to ICS makes me a bit suspicious...

And the fact that anyone who experiences issues like this, when they replace the part, it fixes all these issues?
if it comes and goes, I'd check the port for something when the issue is present. There's likely something lodged in there when it's happening, which gets dislodged when it's NOT happening.
People tend not to protect the port. It can get damaged over time. Also, ICS versions will seem more sensitive to it, because of additional programming and error messages specific to charging and voltage errors added in.

Or ICS screws something up permanently or maybe you're right, and it really is the port, anyway i'll still experiment a while until my jig arrives, if i discover anything i'll update the thread.
Btw, thanks for reading my entire post :highfive:

I just wish everyone who had an issue that needed help was as thorough as you. Most often, posts in Q&A unfortunately look like: "Halp! My fone broked! Whut happen?!?!"
So while some may scoff at the length of your post, they need to understand; when troubleshooting issues, more than enough information is ALWAYS better than not enough.
Don't worry you're not alone.I'm having this issue for about a week and I don't think that it is a hardware issue because my problem appeared when I was doing a restore from backup from custom rom to stock rom and the only thing that I did is that I pulled off the charger while my phone was doing the restore process. The second thing that I think it is not a hardware issue is that my phone is new I bought it two month ago and the USB jig is so clean, I compared to my brothers phone he has sgs2 too and he's USB jig is full of dust and cockroaches and mushrooms and stuff like that but its working perfect. I'm so sorry that I don't have the answer for you but I'm so mad about this problem that I needed to say something and by the way good luck and pm to me if u find the fix

Please take note.
This is not a hardware problem. This is a Firmware/Backup related problem
Had this exact problem on a friends SGS2 and it kept on happening after he did a restore from Titanium. Not that Titanium is broken BUT your backup stored on your SD has a CRC somewhere. What can I say ... It happens.
Just do a complete wipe and install the Rom you want. DO NOT RESTORE YOUR BACKUP !!!
Install everything again as per normal and set it up and you should be good. If this then still occurs then you can be sure its the hardware but this resolved it for him,

I think it's a bit presumptuous to say it's DEFINITELY not a hardware issue. I've seen a TON of posts where people replace the part for the USB port and the problem disappears.
Maybe for someone its is a hardware problem but my problem appeared during restore from buckup.

Did you discover the source of the problem? I am having the same issue with my sgs2 (only 6 months old). I have all the same symptoms - it tells me the USB is connected and the phone is charging, and I get the same alternating symbols when the phone is off (battery charging/temperature warning). I have done nothing out of the ordinary - no system alterations, all is as it was when I got it, other than apps etc I have downloaded. The port doesn't look that dirty, although having read your posts I am inclined to think that this may be the source of the issue? Any help would be appreciated!
solved
Same issue after upgrade, was searching for days ...
Factory restore, but didn't work.
Forced to stop all services, cleared all cache and cleared Ram and after restart everything back ok. Was not a hw issue.

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"
Wi-fi KO
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 !!!

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 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.

I tried with AOSP 4.3.1 but still not able to start Wifi

FYI - Fix for S2s that won't turn on (eg from water damage)

Hi,
I just thought this fix might be useful for people who have a Galaxy S2 that won't turn on at all - eg not even to download mode or charging mode... I applied the fix to a phone today and it went from brick, to booting up!
I stumbled onto a thread on gsmhosting, which points out a really common problem caused by water damage - a specific shorted out capacitor on the motherboard. As it turns out, this capacitor is only used for USB on the go - for USB tethering, mice and such - removing it doesn't affect any other function on the phone. So you can actually remove this capacitor, and the phone will boot up as normal.
Here's the GSM thread:
http://forum.gsmhosting.com/vbb/f258/samsung-galaxy-s2-i9100-short-circuit-solution-1537757/
According to that thread can remove either the capacitor or the tiny IC next to it for the fix... they're on the edge of the motherboard and isolated at the end, so they're actually pretty easy to get to.
For my fix, I didn't have a soldering iron handy, so I just took the plunge and used a tiny screwdriver to carefully pop off the capacitor - I tried to pop it gently away from the IC, to minimize the damage. It popped off perfectly, and after replacing the battery, voila, the phone booted!!
*One weird note about my experience, that I didn't see anyone else report - after the phone booted, the touchscreen wasn't recognized. I thought maybe I'd dislodged one of the cables, but un/reattaching them all didn't seem to help. I then attached the phone to the PC, and used Kies to flash the latest firmware. After I flashed and rebooted, the touchscreen worked fine.
Hope this helps someone! It was such an awesome feeling seeing a dead phone come back to life
Awesome find mate.

It worked for me without a glitch.
I was worried after rebooting cause I had problems with a puzzling "USB memory", but it turned out the MicroSD was not correctly inserted.
Thanks for explaining what the capacitor is for, I was not eagr to remove something that could possibly have a valuable purpose
You think this could be done with the t989 i was running pacman in kitkat i opened netfloix and blam the phone turned off and wont show anymore soigns of life i have found everything in the internet but nothing works
Many thanks
Many many thanks to OP and the original video uploader melanrz1
You saved my 3-year-old I9100! Wish it can last for another 3, all the best!
Is there a way to do this with the t989? Pm me and let me know. Trying to get my old s2 yo work. Thanks
what happen if i just take it off? no replace

[Q] Need MAJOR HELP **A PHONE FROM HELL.*

Hi guys! I'm new around here, I've been lurking the forums for the past year or 2.
I originally had a i9000. Had it rooted, flashed & running 4.2.2 Hellybean, it was a dream, easiest android phone i've ever dealt with.
Today, I bring you a device that is so mind boggling and mysterious, it's ridiculous. Before you ask, yes I've searched and searched countless hours on end & sleepless nights. Trying to work out how to PERMANENTLY fix this device.
Straight up, I'm going to tell you what I've done, what I've tried, where the phone came from, model of the phone & all the useless stuff.
OKAY. Go.
I got the Samsung Galaxy S2 (i9100T) off a friend recently, about a month or two back. He didn't have a back cover for it, and the camera was all smashed up (back camera). It was running on 4.1.2 Vodaphone Stock DVLSH. It had a few issues when the phone got to me.
I wasn't sure if the phones battery was depleted, but I had to muck around with the phone for a couple of hours just to get the damned thing to turn on.
When I had got the phone to turn on, I kept getting "Warning! Battery Disconnected!" messages, this was frustrating. I eventually let the phone fully charged before I mucked around with it and ignored the warning.
When it was fully charged, I went straight to rooting it. I first rooted it by flashing CF-Root and then flashed a custom rom. (Xylon AOKP. 4.2.2)
From here on, the phone started to randomly restart, drop signal, lose battery after random restarts, get semi boot loops.
So I flashed a different stock (XWPL8) and got rid of the Samsung Galaxy SII i9100T boot logo and it was changed to Samsung Galaxy SII i9100.
After this, I then again rooted the phone but this time a different method and used Siyah kernel and flashed Carbon rom 4.2.2.
I still encountered the same problem as Xylon 4.2.2.
So I kept reverting back to stock, re-rooting & trying again.
I've tried countless methods.
POSSIBLE HARDBRICK RECOVERY DON'T TAKE MY WORD THOUGH: I've even managed to HardBrick the device (yes I mean hardbrick, i didn't even JTAG to bring it back... I flashed Dorimax Kernel at some point and it hardbricked it to all ****.) I spent a few days trying to unbrick it when finally I just plugged it into the charged and forced it to internally turn on (i believe) and let the battery deplete (the phone was hot even when i unplugged it. So I let the battery drain.) Yes I even battery pulled and tried to reboot it to see if I could boot recovery or download or the rom even before I tried any of this! (absolutely nothing.)
I took out my SIM card after a full day of letting it drain (just to be sure) plugged it in, took out the battery while the charger was plugged in, put the battery back in, unplugged the charger while holding power, and plugged it back in and I got the charging logo booted into download mode after 80% charge and flashed stock again.
Now the problem(s) with the phone:
SEMI-BOOTLOOPS: Every time i've rooted the phone and even flashed different roms just to make sure, it does a "semi boot-loop" I've searched everywhere for people with the same problem but found nothing on it.
What it does, is it turns on (boots the samsung logo.) turns off, turns back on, turns off, turns back on etc and then after about 2-8 times of doing is usually it boots to the ROM and the phone works for awhile.
RANDOM REBOOTS: I don't get these much anymore since I found a solution where someone had just folded up a receipt and pushed the battery up against the prongs because it had about .5mm movement off the prongs. This fixed most of the random reboots and don't see many anymore.
SLEEP OF DEATH!?!?!? OR JUST A BLACK SCREEN THAT DOESN'T TURN BACK ON!?: This one I'm not 100% sure what it is, I read it's the S.O.D (Sleep of Death). Which is common on 4.0.4 and was apparently fixed in later Android versions. But sometimes, when I lock my phone, or my phone goes to sleep, the screen stays black even after I press the home button or the power button, at first I thought just restart it by battery pull or holding down power like everyone says, yeah it works, my phone boots up and does a semi-bootloop and goes back on eventually, but one day I left it on in the mysterious S.O.D. and waited 5-10 mins pressed the power button and it unlocked... This one really has me baffled and it does it a LOT.
REALLY BRIGHT SCREEN AFTER REBOOT SOMETIMES!: Okay, so sometimes when the phone finally turns on, the screen is really bright, like the brightness is still on half, but it's a lot more noticeable on how much brighter it is, it's nearly like a white.
It's really really BRIGHT. Phone shouldn't be able to look/get that bright. After a reboot though it goes away and goes back to normal but this leads me to believe something to do with the battery just a hunch.
RANDOM FREEZES!??!?: Sometimes the phone will just randomly freeze, I can be doing something and it'll just freeze, it won't turn off, I still get picture on the screen but it's frozen and I can't do anything until I either battery pull or reboot it by holding down the power button.
Before anyone asks, yes, I Factory Reset from recovery, Wipe Cache & Dalvik Cache before, I flash a new rom etc.
- My GApps matches with my Android versions each time.
- The ROMs I have flashed are compatible with my phone.
- And I've made sure everything I have done is completely compatible with my phone and android version.
What I think!:
SEMI BOOT-LOOPS:
This one, I don't think much of, it's got me baffled. It could be something to do with the Boot-Loader, could be something to do with a bad flash (but I've even tried double flashing a single rom.)
the eMMC could be damaged in a certain way that it causes these self proclaimed "semi boot-loops"
RANDOM REBOOTS:
This one, I've pretty much fixed with the help of lurking the internet over and over for hours, so this indicates a battery problem, will be replacing it this week. (Yes I'm aware that this battery problem could be causing everything else to play up and that it could all be due to the battery but can we leave the battery out of this just for now so I have more options on how to fix it.)
SLEEP OF DEATH!?!?!? OR JUST A BLACK SCREEN THAT DOESN'T TURN BACK ON!?:
I believe that this could be due to either a high load on the CPU (maybe not so much high but a really low load that it goes into a state of nothing for awhile.) It drops into a mode where it's turned off (something bigger than deep-idle.)
REALLY BRIGHT SCREEN AFTER REBOOT SOMETIMES!:
I haven't changed voltages or messed with any voltages on my phone, but I believe that it does indeed have something to do with the CPU & GPU voltages or even the BATTERY Voltages either undervolting or being to high.
RANDOM FREEZES!??!?:
I think this one is something to do with my phone not liking the voltages stock set to it.
I read that somewhere Freezing the System Alarm Clock can fix the random reboots, so I've done that and also pushed the battery up with a bit of receipt so it touches the prongs completely.
Anyway, right now, the phone is on Stock Kernel with CWM Recovery6, with PacMan's 4.3.1 Nightly release on XWLP8 Baseband and it still does this all.
I know i'm asking for a lot of help and I'm probably going to get yelled at by Devs or forum mods or some body because I've done something wrong.
But if it doesn't belong here, move it please.
IT TRULY IS A PHONE FROM HELL.
-Thanks, Just another man who wants to fix silly problems for fun.
Youve said "dont mention get a new battery".What if that is the problem.
Maybe the phone has water damage, or it needs that hawkerpaulls scripts run.
Youve just got to try free stuff, then maybe splash a bit of cash I.e battery.
Nothing software/firmware-side is fixing this. Phone has major hardware issues going on. I wouldn't bother beyond trying the 'free stuff' TheUnderling mentioned.
erm - I'm agreeing with you on this 'phone from hell!' also agree with @theunderling and @MistahBungle - it doesn't sound like its worth fixing if the free stuff doesn't work - sounds like it would probably be cheaper to buy a second hand s2! Don't think dori kernel had anything to do with your 'hard brick' - I've been running dori for some time including the experimental builds, dori tests everything himself as do his team of testers - the 'd team' and I have never known him to release anything that even soft bricks let alone hard bricks.
Good luck :cyclops:

Sorry, I was half asleep when writing all this! I am getting a new battery this week! But I wanted to have a go at trouble shooting it but crossing out the battery from the list of problems seeing as it's being replaced this week @theunderling

It may sound like it @MistahBungle but I have faith and I come down to being very patient with technology even when I do reach ticking time bomb mode. I believe I can fix it if I just get the right help !
If the new battery doesn't do anything, It might be the logic board and i'll just go buy a new one.

@Jimsilver73 It really is!
I'm not the most wealthy person or have money to just throw at things like new phones etc etc. I'd love to see what I can do on my side and try and trouble shoot every problem for even the simpilest of DIY Solutions. I get a kick out of mucking with phones and computers.
Your probably right, but I was thinking that does Dori kernel keep stock voltages or does it change the voltages at all? Because it just managed to Hardbrick its self a few hours after flashing it which was odd, which led me to suspect that my phone didn't like the Dori Kernel & Carbon Rom Combination!
@theunderling I will try that Hawkers script by the way!
Is this the one? http://forum.xda-developers.com/showthread.php?t=2100558
Phone having no back cover and camera smashed suggests that there is a physical damage to the phone, i wouldn't even try battery to this one, it may just kill the new battery if there is some kind of water damage, tho you seem like having fun trying to repair it Yes, that's hawkers script, use it and couple of ROMs, (ICS,GB etc) to see if there is a software problem. If you can dissamble it, you can check if there are some contact problems between pieces.
Hi @Dakura thanks for the reply!
The camera isn't smashed completely, but at fist I thought that the camera would be screwing up the phone in someway.
I know for sure as well that there is no water damage, and the phone was just sitting around he lost the back cover randomly after he had bought an iPhone 4S.
I can disassemble it, I just need to find my little screw driver I use for stand-off changing on PC cases.
I read somewhere that the proximity sensor has a bit to do with things, so seeing as the back cover isn't on, that maybe dust got into it while it was in his draw and that's the reason for screen-offs? because the phone is still responsive. I can receive calls & text messages just the screen is black and doesn't come back on.
The warning in 4.0.4 "Warning! Battery Disconnected!" leads me to think that in versions above 4.0.4 (4.1.2 for example) don't have warnings and the phone just turns off.
**major update**
@Dakura @theunderling @Jimsilver73 @MistahBungle
Hey guys, so I've just taken the back CASING not the cover. Off the phone.
I've been looking for breaks in solder points on the Logic Board and around it.
- The Camera ISN'T smashed it was the lens on the case..
- Looks a tad dusty.
- Semi Boot-Loops have disappeared! booted the phone with the case off and the semi boot loops are gone tried booting multiple times each time with success!
- No breaks on the logic board from what I can see as far!
- For some reason the Camera app would not connect to the Camera. "Can't connect to Camera!" maybe the camera flex cable isn't in properly.
- First boot with case off, battery gave false reading of -1021032418914 (something along those lines). That's usually caused by a lose battery correct me if I'm wrong?
- Everything seemed a lot more responsive and working.
Hmmm.
So removing the screws and taking the back casing off made the Semi Boot-Loops go away.
Maybe a part of the back casing was pushing on the Logic board and shorting it out?
Maybe the screws torque where messing with it (e.g. on a HDD with computers the simpliest change in toque on the screws in the HDD can screw the HDD.)
But the torque of the screws where very loose.
Any ideas are much appreciated!!
Yep, probably a short-circuit or dust problem or displacement somewhere around there. What you said proves that somehow the phone was physically damaged. You may need to actually disassemble all the pieces, inspect them and put them all back together, and it still may not work, for now, try cleaning the dust and tighten the screws, fasten the board.
@Dakura thanks for the help today Dakura!
Finally got around to putting everything back together after an evaluation, made the flex-cables all snug and tightened up the screws a lot!
The phone appears to be working now.
at 100% it even vibrates now when i tap things it never used to.
I couldn't quite locate the problem, but I have a feeling that one of the flex cables could have come loose but only just enough to generate fluctuation of power between full and under to keep the phone on.
Hopefully the phone stays stable!
@theunderling thanks for recommending me HawkerPauls Nuke script, I'll be using that every time I re-rom my phone from now on!
Will update the thread on a possible fix for anyone else with this problem.
It's always good to run through every possibility and solution to fix problems before going out and blowing money.

Honor 10 reboot randomly

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.

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.

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

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...
