Hard brick ? - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
My phone seems to be hard bricked: black screen, nothing happens when trying to charge it, not possible to put it in DL mode, and even usb jig is not working.
Now I'm fully aware of the risks that go with a bad flash, but what is weird in my case is that it happened out of nowhere: I was on stock rom, phone was suffering from a bad case of slowdowns/random freezes/etc so I decided to put CM 11 on it. Like a phoenix my phone rose from his ashes, battery was holding for a full day instead of the usual 3 hours, no more freezes... but then after 2 days of working like a charm, I just found it plain dead on my desk.
Has it ever happened to anyone, suffering that kind of brick a few days after flashing but not during the actual procedure ? Does anyone has a potential solution other than replacing the MB ? (not really worth it on a 2 years old phone IMO, since there is little chance that I will stumble upon a free MB, and I'm not even sure that it would solve anything anyway)
Thanks for your help !

Nothing to do with the flash. Fact - electronics fails/dies. All the time. All electronics. Often without warning & for no apparent reason other than that's the nature of electronics. I don't know why people are so surprised when this type of thing happens.
Motherboard replacement or new phone - a motherboard replacement will fix the phone; one or more components on the motherboard have obviously died.

http://www.parts4repair.com/categories/Samsung-Repair-Parts/ seems to stock reconditioned motherboards for the S2......double figure prices rather than mid triple figure prices for a new phone.....you do the math.......
My wife says I'm a phone geek....She's probably right

[Q] Random Rebooting and Overheating X10

I had bought my xperia sometime around October'10 & updated it to 2.1 when it was available & then started facing this problem. The battery gets overheated, specially when charging, & when any activity is performed on the phone then, the phone goes into a loop of rebooting, stabilizing only when the battery cools off. Not only that, when on the move, apps like maps is initiated, the phone often reboots, so much so that it sometimes happens 4/5 times in a day, 2/3 times together. Since yesterday, the phone rebooted more than 10 times, twice with a sudden jarring sound while closing down. Also sometimes there is a burning rubber smell coming from the back of the battery. I have tried everything from reinstalling the android software to sending it off to a repair centre only for them to say that it is liquid damage when I know for a fact that no liquid has EVER touched it. Please someone help me. What do I do? Would downloading a custom rom or Zzdizus ne wcustom kernel help. Anyone got any working fixes
It sounds to me like a hardware problem, since you've reinstalled the firmware.
Why not, try zdzihus' beta 4 or wolfs' CM6.1.3 to see if it will be the same. But if it's the same, then you'll need a service.
I've had this problem too. I sent it to the repair center too (KPN Netherlands). But after 3 times to the repair center the problem still occurred. After the third repair I received a new X10 (with 2.1 pre-installed).
So I'm afraid there's no quick (software) fix. It's definitely a hardware problem and there's many people reporting this problem. Some get it fixed by having the motherboard swapped, some got a new phone, like me. I hope you still have warranty and manage to convince them is't not liquid-damage, because otherwise you're probably screwed.
I have this problem too, i don't think a rom upgrade will fix this, reading at different threads i am not alone with this problem, please read this:
http://forum.xda-developers.com/showthread.php?t=831658
I am going to get mine in for repair see if they can fix it, otherwise i am screwed.
Chances are services won`t be able to find the reason, and odds are good they will just hand you a new device.
Is there anyway whatsoever to stop the rebooting without paying for repair and without sending it to a repair centre (they keeps saying its liquid damage when I know its not). There must be something because this problem didnt occur when the phone was on Android 1.6 at all.
its not a case of roms or 1.6 vs 2.1 etc this is a problem which looking at the SE forums they know about however are not doing anything about
its a problem with the motherboard in about 1/5 xperias from what i read so not everyone will be affected but for those who are (tell tale sign being a burning smell when the battery is removed combined with random reboots) then the unit has to be sent back to SE for re-fit / replace.
however, and this is where the worst problems are, from what i read if the white sticker behind your back cover had red dots on (yes i know most peoples will just from natural humidity) but this is the water damage sticker and they wont fix it for free if this is marked (red dots)
also you need to have all the proof of ownership / warranty receipt to send off with it, so if your like me and got your xperia off of ebay they your screwed
sorry to be the bearer of bad news but this is the problem, if you have it its hard to get fixed and if you dont then good for you but the likelyhood of you getting the problem is not too slim not to think of taking out insurance
There must be something I can do though. The phone only started overheating when I updated to stock 2.1 so there must be something
This definitely sounds like the mobo problem that's been plaguing the x10. Sadly to say, there is no fix you can easily do without switching out the motherboard. I feel like the watermark sets itself off when the device overheats. Same thing happened to me, and I bought my first x10 overseas so I had no warranty. Your update to 2.1 probably just coincided with the issue starting.

What if I get zzhidzu's new custom kernel. It undervolts. Would this sstop or at least reduce the battery overheating problem
Please some expert respond
Because you're undervolting, it will probably not overheat as much, but it definitely will not solve the problem. The motherboard is already compromised. At first, my faulty x10 would only reboot once every few days, but as time went on, it became more and more frequent. Now, I can't even get it to boot past the carrier splash screen. Swap kernels for now, but plan to start saving money either for repairs or a replacement phone.

Does anyone have any fix whatsoever?
any at all? to at least significantly reduce the rebooting
If you boot your phone without a sim does it still happpen?
its defonatly worth a shot i recon ill give it a go also
Is there anyway I could maybe replace the motherboard myself or even do something to my phone to stop it from rebooting because of the battery? This way when I feel that its hot I can turn it off myself when I am ready.
There must be something I can do. The phone is literally unusable :'(
@Omega Red
It still happens but not really as much. But what's the point of having a ohine if you cant call lol
I have just switched back to stock 2.1 and my phone is behaving very well now.
Does anyone know how much it costs to get the moboreplaced outside of the warranty in UK pounds?

Lapdock battery issue

I bought a refurbished Lapdock from All4Celullar and it works amazing while plugged in, but it doesn't work if plugged out.
I live in Argentina and it would be more expensive to return it, so I'm trying to fix it myself.
The battery indicator works while plugged in (3 dots first time I touched, 5 an hour later) so I guess there is a battery inside but with some malfunction.
Does anybody have any idea about how to repair it? Or things to check to identify what's the faulty part?
I googled a lot and it seems I'm the only one (I guess the lapdock without battery powered is such an evident flaw that everybody returns them). I'll be very grateful if you can give me a hand, at least pointing to something I should read.
Did you ever find a fix for this? It seems that mine has developed the same problem. MAJOR issue for me, I literally love the little guy and don't have the money to replace it right now.
I guess if nothing pops up, I might just have to find someone who is willing to buy it despite the issue.
In my case, I get 5 flashing lights when I try the battery indicator
I know double posting is frowned upon, but I wanted to present a slightly more obvious solution to this issue (because it's what I did)
Try to send it in to Motorola. If you haven't had it for a year and bought it new, or as a refurb, you should be able to warranty it for repair or replacement. I sent mine in a couple days ago and they have it currently. Hopefully I'll get it back and in working order soon.
The worst that might happen is they tell you no. IF that happens, then you might want to try to find another way to fix it.
It's always surprising how frequently people don't think to consider manufacturer's warranties. Typically you don't need a receipt or anything, I didn't for my lapdock. I look forward to getting it back.

[Q] Battery "discharges" out of the blue

Hi,
My wife's been complaining about her sgs3, i9300a phone a lot lately, so I've been taking some time of to have a long hard look at it.
the phone in itself works quite well, it is somewhat guarded (she tends to drop it a lot but most of the time it's actually in it's case) and we've switched the screen once (well, not the screen, the top half of the phone to be exact)
the phone used to have a stock 4.1.3 (I think) samsung rom on it for the past year, it's been working well untill a couple of months ago I think and it does still function properly on light use
so what is the issue?
if you'll start a game, or anything that'll cause the phone to heat up - the screen would flicker a bit (not always) and the battery will suddenly report to be down to 0%, shutting down the device right after.
this sudden discharge is obviously not real, as the minute I connect it to a charger and boot up the phone it shows it's last charge before the phone was shut down - however the issue keeps on repeating itself over and over again.
If the phone is connected to a wall charger (or a pc via USB cable) this doesn't happen.
I've been trying to install a kitkat on the device (it have been working slowly so she needed an upgrade) yet the issue persists.
I've been reading around the Internet, some claim it's a faulty battery issue so I'm ordering one from eBay, however - I can't shake the feeling it might some other faulty hardware, perhaps a memory chip gone bad? as I can't see the connection between a bad battery and a flickering screen.
Truth to be told - I'm not a fan of android, or samsung, so I don't know much of the history of problems with it (if there is any) and I've been hoping that there is someone around here who might encountered (or heard) about my issue and would be able to shed some light for me.
thanks in advance!

Yeah... I'm planning on stealing my boss S3's battery for some testing later on today if he'll ever decide to show up...
perhaps shouldn't have told him that beforehand
I did hope someone encountered and fixed/learned about this problem as the device has 2 years of history at least...
if it'll come to motherboard switching I'll just force the little lady to switch to a real phone such as an HTC, or maybe go to WP
It was the battery..
Perhaps I should've guessed it by the fact it was REALLY hard closing the case... but it was only after I saw a normal battery that I noticed the real difference.
so for future reference to whomever might meet the same behavior - my battery was about 1.5 the size of what it should be and was quite round,
better call those Samsung representatives and get a replacement before it explodes
Anyone has experience with those 4200Mhz batteries? worth the money or should I just get a genuine one (it cost about the same in here, like 4$ more), the reviews are quite mixed.

Finally bit the dust

Man I gotta say I'm super bummed out. My battery recently crapped out on me, so I replaced it on my own because I just hit outside my two year warranty.
Well yesterday my phone shutoff randomly and is now bootlooping over and over, and nothing has resolved the issue (flashing factory software etc). So I now have a completely useless Nexus 6p that is in perfect physical condition with a crapped out set of cores that wont allow the phone to boot. I know there's the custom kernel that allows the phone to run off the power efficient cores and I certainly recognize the time spent and the skill required to create something like that. I'm just salty that my expensive phone is now a paper weight.
I made the mistake of buying this direct from Huawei an not from google (it was a better deal at the time and now I see why) and they all but laughed at me when I asked for assistance in replacement for the battery issue, and I didnt even bother asking them about a replacement now that the phone is completely dead.
I talked to google just for laughs and they told me what I knew I would hear, that I didnt buy it from them so I was screwed. I guess long story short is that out of all the devices I've owned this has probably been one of the best while it worked and the worst I've ever experienced when things went wrong. Right at the two year mark it self destructs? I still have my original htc evo that works! lol
/EndRant :silly:
If you want to donate it for parts, I need a new metal housing and LCD for mine.
Mine is still running on all 8 cores and battery replacement was done in August of last year and is still running fine.

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.

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

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...
