Note 8 - BSoD (Reversing the Battery Flex, became Costly for me) - Samsung Galaxy Note 8 Questions and Answers

With a very Big Blunder, I just tried to Boot my Note 8 with Galaxy S7 Edge Battery, without taking care of the Battery Terminals. Ended up with a Dead Phone, No Boot, No Download mode, No Recovery not even any sign of Battery Charging....
Failed Experiments:
1. Tried to Turn ON after 2 Hours of Continuous Charging Plugged
2. Tried to Connect with my PC (No Signs of Detection)
3. Tried to Turn ON with Volume Down Key Pressed
4. Tried to Turn ON with Volume Up Key Pressed
5. Tried to Turn ON with Volume Up & Bixbe Keys Pressed
6. Tried to Turn ON with Volume Up + Down Key Pressed for even 60 seconds passed, but no Luck
So, it may be a Hardware Fault... Anyone can guide, what worst could happen with this kind of Silly Mistake!!
Could it be Recoverable? Battery is giving 4.5V, Charging Flex Board (Sub PBA), upto Sub PBA Connector is giving 4.5V while connected to Charger.
If anyone can help me in this type of Fault, will really be appreciated. (Thanks in Advance)

yep tryed it .. theres a red light on the power button whats that about?
Have you tried removing the charger and battery, then plug the charger back in, wait a few seconds, then put the battery back in (with the charger still connected). This usually solves the ol' red light/no power issue on my hermes. I only normally have to do this though if I accidently let the battery run completely flat.
Other than that, a red flashing LED when the power button is pressed on a sony ericsson device usually indicates an error. The LED flashes error codes based on either hardware or flash problems/errors... though I don't know if this will apply in this case on the basis its completely different hardware/software to "standard" SE devices.
hmm now the red is on constant on the power button i tryed the few things you guys mentioned but no luck maybe it need s a good charge again.. DOHHHH!!
i flicked throught he manual there is no detail about what the red light on the power button means
Hmmm - on my Wizard when the battery went flat I couldn't use a USB cable from the computer I had to charge it from the Wall socket. Your Xperia should have come with a normal plug to plug into a wall socket (you attach your USB cable to that).
why not call the X1 support?
after overnight charging there was no change, so i manged to boot it in flash mode let it on charge for a few min then i reset the phone and bingo it rebooted.. woooohoo
I followed your instructions.
But I cannot boot in flash mode (4colour) even though I charged it for a while, then press and hold Volume Down + Power together.
The illumination lights just flash and turn off.
Is it always like that? If you leave your phone with totally no power in the battery you can not start it later, or you have problems starting it?
I ask because I saw a couple of topics for that issue in the forum. Does everyone have this problem or it's for some devices only?
Do you use the origin SE-charger? I had the problem once and used the charger of the diamond from my wife since I was too lazy going up into the arttic searching for the carton. But the charger of the Diamond has too few ampere, so the battery of the Xperia didn't received enough power. Even using the USB-port of the computer didn't worked well.
So try using the origin charger and also don't let the battery get too low.
aah, I use the original charger of SE X1.
The Cause of problem:
+ I set the alarm. After it had notified, it still snoozed and ran out of battery.
+ I didn't know the current phone without power when I woke up. I turned it on and it had to used little power left inside (the saved power - I guess). From that point, X1 cannot be charged even you plug it all day and all night - different with other phones.
(My Cingular 8125 can be charged after 24hours charging continously).
* Any X1 and other PDA using window CE can suffer that problem.
The Solution:
* For other phones: just plug wallcharge in, after 24hours, it can be charged.
* For X1: You have to come to BOOT MODE (4colours)
(but if doing like above posts, you cannot come to boot mode with no power inside battery)
1. Remove the battery.
2. Plug to wallcharge.
3. Hold the volume Down + Power buttons.
4. Still keeping hold those 2 buttons in one hand, another put the batter back inside.
5. Wait until it turns into Boot Mode, released them and charge in 15 minutes (to make sure that it would receive a little power)
6. Remove the battery and plug back. Restart in Normal Mode and charge it.
* It is my experience after many trials in 9 crazy hours
Thank you for that useful post. It's good to know that there is a way out of that situation.

yeah omg,
thx for this this should be a sticky
i was listening to my music and got an notification that my battery is low, not even 2 minutes later my phone went off
and couldn't put it back on. the weird part is that the 10 prcnt of power drains that fast my music isn't loud (via media xperia panel - phone volume was 100% but music player was full for 2-3 blocks)
but anyway, thx
pek, you're a star. flawless fix.
When my wife's X1i run out of power completely two weeks ago I also first tried to use the original SE charger. No effect after 6 hours charge.
Next I tried my lab power supply which can provide 5V/3A current. It took less than an hour to charge the phone making it fully workable.
My car's charger can fully charge X1 from 20% battery to 100% in less than 45 minutes. 2A maximum current restricted. Fast charge seems have no influence on battery's life.
Also if you have a wall charger for X1 battery you can charge it outside the phone for some time (20 minutes usually enough). Also works.

[Q] Broken Xperia Z

Hi everyone!
4 days ago i washed my phone for about 10 seconds, phone worked normally. After 1 hour i saw water went into both front and back camera. I got out all flaps and after some hours cameras were functional again. After even more hours buttons started to act weird. Sometimes power button wasn't working, sometimes volume up was acting like power button and so on. I tried to restart the phone, sometimes it went into safe mode(probably volume button was pressed by itself). Finally I couldn't start the phone at all(perhaps the power button stopped working at all).
After that i calmed down and put my phone into rice(hoping that would absorb water if any). After 24 hours i had no luck. When i had connected my phone to computer, the led was red, phone vibrated 3 times and then again and again.
Next step was to open the phone( removing the back with a hairdryer), took out the battery and trying to dry the phone with hairdryer. Still no succes. When connecting to PC and start flashtool, my phone wasn't recognised. I installed Sony Update Service (SUS) and then when i connected my phone i heard that sound you often hear when connecting a new device to an USB port. Now my phone is seen by flashtool, but it's always in fastbootmode. I even flashed CWM and it worked.
The problem is that it seems volume up is pressed always so i can't enter in flashmode to flash 4.4.2, it always goes into fastboot.
When on battery the phone is dead at all. Still when i try to charge the phone, it starts, displays Sony logo then shows that it's charging (at first that battery was empty but after 2 hours it got full charged). If i press power button it shutdown.
To resume, when on battery nothing happens( the battery could be dead). When plugged to wall charger the phone starts charging( so battery could work). Power button does nothing at all when on battery, but works when phone is charging or when connected to PC in fastboot.
If anyone had any idea what I could do I would be very appreciative. If you have any questions don't hesitate to ask me.Thank you very much for your support!

Did you connect phone holding volume down key or are you connecting usb after that pressing volume down key

Even if i down't press anything, just connect the phone to usb, led is blue, that means it's in fastboot mode...so i think volume up is stuck, pressed.

or the volume pcb might have shorted
Please remember this for the rest of your life:
When you notice that water has went into your device.... TURN IT THE F OFF AND LET TIT DRY...
Using it while it's wet from the inside is really bad.
Update Guys
Today I've replaced that yellow connector that contains power, vol up and vol down buttons. I managed to enter flashmode and flashed the newest official rom .233. Power button and vol up work like charm, vol down is dead.
The problem is that my phone is stuck on safe mode(probably because vol down is stuck). I want to know if there's any solution to get rid of this safe mode. I read somewhere that changes can be made to the kernel so that vol down will be disabled for ever. If you know any ROM, any mod, whatever that disables the vol down button i'll appreciate your help.

XT890 doesn't start at all.

Hello. This morning I've turned off the alarm, turned on WIFI and went back to sleep. I can't tell for sure, but I think the battery was low. During the next 2 hours I checked the time several times. I don't remember accepting any OTA. Eventually I got up, tried to check the time and the phone was off. I tried to turn it on, no effect. No matter how many times and for how long I pressed and held the power button, the green LED only flashed for a split second and that's all. I plugged in the charger, and the LED stayed lit -but- there was this barely noticeable flickering. Charged it for about 30, 60, 120 minutes, didn't start plugged or unplugged. I went to work, 8 hours later (phone was unplugged) I tried to turn it on again, this time the LED doesn't even flash, but when charging there is no flickering. No combination of buttons works. Windows doesn't find the device, neither does RSD.
I've never done anything 'custom' to the phone. The last change I made was setting the alarm to turn off by shaking (yesterday, never used this option before).
Is it dead?
Try taking SD card out and holding Vol down and then Power for 20 secs, then let go of Power,
Already done that, nothing. No matter how long I charge it now, after unplugging and pressing power button the LED doesn't even flash. Could it be a battery problem (before its death, it would last for a day)? Is there any way of recovering my data without buying a new one?
Try opening and disconnect battery for a bit.
I'll do that as a last resort, on weekend maybe since I don't have the tools with me. Any other clues?
Nobody knows how to help me?
I'm going to make a factory cable. Will this alone allow me to recover the data? Or if I'll be able to flash the phone, can I recover the data afterwards?
Also, I'm not sure if I understand correctly: does the factory cable recharge the battery or not? Is there a way to recharge it when removed from the phone?
Try to use medfield unbrick script. If You have only green led it seems to be bootloader error so this script should bring Your phone to life or Your phone has broken emmc and You can start looking for a new logic board. Good luck.
I've installed the drivers, but Windows and XFSTK don't recognize my device at all. Factory cable also didn't help. I liked my phone very much. :angel:
Did You enter medfield mode using combination with camera button??
By a combination you mean holding the camera button and connecting the phone to a pc? I tried that.
Disassembe Your phone, pull out battery, push power button for a 10 sec, plug in battery, push camera button and connect USB. If it wont help You I don't see any hope for Your phone.
Well, new option to try is a new hope. I'll try that on the weekend. Could you please be more specific:
1. Pull out the battery.
2. Press the power button and wait 10 seconds.
3. Insert the battery: should I be still holding the power button at this moment?
4. Press the camera button.
5. Plug in the usb cable (factory? regular?) - should I be still holding the power and camera buttons?
Battery trick is only to discharge capacitors. Sometimes even phone is dead it can turn on in some strange mode and then You can't boot it to flash. Thats why You need to pull out battery, push power for a few sec to completely discharge motherboard and just release this button. After that You can just plug in battery and continue normal unbrick process - so hold camera button only and connect regular usb cable.
You can also try reset option instead of pulling battery out. To do that do not disassemble Your phone but just plug in regular USB, when phone starts (green led) hold power and vol- until green led goes off and then quickly start holding only camera button.
I have no more ideas.
Ok, I've tried everything. Nothing brought my phone back to life.
Thanks for all your help.

Mi5 won't start

Hi,
My Mi5 won't start now. It was having about 60% when I switched on NFC for the first time. I may have switched the NFC on and off a couple of time. Then I inserted the phone into its case , and by mistake the wrong way which might have pressed the power button / volume button , while I was inserting the phone into the case I noticed the phone was turning off. Quickly I realized the phone went the wrong way into the case and I removed and reinserted it and then pressed the power button, but nothing happened. Tried pressing volume up / down / power button but no use. But the phone was warm.
Now, the only sign of life in the phone is when charging it using the regular original charger. The light is initially purple and then turns to green but then it switches off. Tried connecting it to laptop but does not show anything. Also, the safe mode boot method does not work. So, the phone does charge but pressing power button does not turn it on but just makes it warm (some kind of startup loop)
I've been using the phone for last more than 2 years and it has original setup and updates are automatic and regular.
Just don't want to trash the phone if it can be revived.
Looking for advise.
Thanks

Please help! Can't turn on my phone :(

Hello everyone!
I was charging my phone last Wednesday night, last I checked was the battery was at 92% , then after 15-30 minutes I checked my phone again and I found out it was dead. I tried to charge it again, but it doesn't show or indicate that it was charging, I tried pressing the power button, but no display, I tried hard reset, and it displayed the logo for a while then go black again.
I tried charging it last Thursday evening and the phone suddenly blinks red light for about a minute or more, then no reaction at all.
I tried doing some combos from forums like :
Tried doing while charging press voldown + power button = blinks a red light once
Tried pressing voldown + volup + power button = nothing happened
Tried pressing voldown + power button for 15 secs, then volup + power button for 15 secs, then voldown + volup + power button for 15 secs, nothing happened.
I dunno what to do now, please help, service centres are I think closed here in Philippines due to some implementation of the government against COVID-19.

Mine's bricked and still waiting for it to be shipped to china to be fixed
same situation Sir. Any update on your phone now? what measures did you do? thanks!
today my phone suddenly restart then freeze then restart then long beep for about 10 sec. then dead and can't be power on any more help
Same with me. My Phone suddenly froze, and couldn't turn off or close the game (Genshin Impact) and a high pitched noise was coming from the device.
I Tried to force it to shutdown, but then it can't be turned on at all
The phone itself can't be turned on at all UNTIL some point when the phone reach 0% Battery (yes, I don't even know when does my phone reach 0% Battery)
When the phone reach 0% Battery, you can charge your phone and get some small red light indicator response, BUT IT STILL WON'T TURN ON
Then, after some couple of minutes, the Small Light Indicator would be off, the phone would be look like they're fine, it will show the battery percentage as usual when you charge your phone when it shutdown. BUT IT'S NOT FINE YET.
When I tried to turn it on (no matter Via Long Press Power Button/Power Button + Volume), it would stuck at ROG Logo, then it completely shutdown and can't be turned on again.
