Hey there. I have my Galaxy S II (GT-I9100) for about a month, and since a couple of days ago it has been behaving very weirdly about USB and charging.
First of all, the phone thinks it has USB connected at all times. When I go to the settings menu try to enable mass storage it says USB is already connected, even though it isn't!!!
Sometimes when I start the phone it goes to that USB Kies screen and says "connected", when absolutaly no cables are connected AT ALL!!!
When I turn the cell off, remove the battery and plug it back in, without turning the phone on, the recharging battery icon appears, but blinks with a drained battery icon with a yellow exclamation sign and a thermometer which I sincerely have no idea what that means.
It also takes ages to recognize the power charger or when I really connect the USB cable. And finally, when I take them off, it also takes a while to "perceive" they're off and remove the charging lightning from the battery icons.
PRETTY PLEASE, SOMEONE HELP ME OUT, as I don't have time to take the phone to service, and didn't really want to do that
Thanks!!!
This has also happened to me and loads of other SGS2 users! Although usually it only happens sporadically and not constantly. It seems that it's a bad soldering job or dust/dirt has gathered in the microUSB port. You might be able to fix it, if you're *really* careful.

Last night my phone wouldn't even start charging, so I decided to take matters into my own hands. With the smallest screwdriver I could find, I carefully 'lifted' the tiny PCB in the USB jack while blowing in at the same time. Sure enough, some sand particles fell out, and I haven't gotten carmode'd in nearly 13 hours now. Previously it would do it once every 15 minutes. So far so good, it seems.

Thanks for the help... but what is PCB? Is it the connector inside the "hole"?
Tried that and it stopped thinking USB was connected the whole time... on the other hand, it doesn't detect when I connect the USB cable
Lets try keeping 1 thread
Therere are other threads about it.

You can't talk on plural when you only point out one thread. And I've read that, but it isn't the same as my phone doesn't go in "car mode".
My phone's problem only resembled a problem JaX3RiR briefly mentioned in the middle of the thread.
I tried googling it before posting anything anywhere, but couldn't find anything useful.
Please don't try to look like a smartass like that and embarrass yourself. If you got nothing to add to the thread, it's best if you sit out of it. It's much more appreciated when helpful people like JaX3RiR post...
Hi,had the same problem,tried reflashing back to original firmware,but still had the same problem,,the only way i could boot the phone was through recovery mode,(reboot)Had to send phone back for possible repair??cut a long story short they sent me a new phone,,They said they couldnt repair the fault,something to do with the usb charging system,,So i would advise anyone with this specific problem,to send phone back,and get a replacement..hope you get it solved
Thanks mate, I sent mine today as well... I hope they act the same with me, as I'm afraid customer service around here always tries to incriminate the user not to use the warranty...

There is no reason to be angry, I'm just trying to help, and just wanted that we all post in one thread, so it would be easier to track later.
I just posted longest thread. Here is another one if it helps to justify:
http://forum.xda-developers.com/showthread.php?t=1151863
I'm pretty sure you have the same problem. Sometimes Vlingo starts, sometimes phone thinks its charging, when trying to boot it shows battery image and won't boot, can boot only recovery and do restart from there.
Get of the high horse when people are trying to help you.
Are you sure you didn't connect USB cable upside down or bended USB port with the cable?
I have no idea what Vlingo is, and obviously I didn't connect the USB cable upside down. I don't think I bended the port with the cable since it still recognizes the cable for charging or booting and going directly into Kies mode, for example.
I am not on any high horse when people try to help me, as you could see my response towards the guys above. Your post wasn't sounding helpful at all, you were just sounding like "hey, you dumass noobie, don't open a new thread for yourself, check the forums first".
By the way, I also took a look at that thread you posted before posting mine, but I have no idea what is "car mode" on my phone...
Sorry if I sounded rough. I thought it is similar issue, so I posted link to longer thread. I had this issue myself.
Peace. Let us know what the service say .
This happened to me one week ago while on holiday....that temp indicator while charging plus the other stuff you mention....
Plus the phone went into flight mode and won't come out....
Got home and did a reset and phone now doesn't recognise sim card...
great phone but I'm a little disappointed

Hello,
Had the same problems aswell, only mine had a bunch of other problems aswell:
When I shut down my mobile it restarts itself and then shows a yellow exclamation mark with an tempgage. Only way to turn on my phone is to connect it with the charger, turn of my phone again, remove the charger and then the phone turned itself on again but without the temp gage.
My phone also thinks its charging when it is not, and when I am actually charging it, its not charging.
Also my PC does not recognize my phone so I am not able to update it.
I have also sent my phone for a repair, I will keep you guys posted.
greets from the netherlands
Yep, mine only got fixed by going into service. It got its mainboard warranty switched.
T- Mobile sent me a replacement phone
They seemed to know the symptoms when I explained what was happening
Same fault for me. Mainboard replaced, works fine now.
Sent from my GT-I9100 using XDA App
How did you guys get it fixed? Did you have to ship the phone out somewhere? How long did you have to wait to get it back? What was the process?
Thanks.
Mine is going to be repaired in two weeks.
I was the 8th SGS2 since tuesday which came in the repair center.
The repair guy said it is a manifacturing fault.
The phone gets hots, and outside temperature is cold, so it makes moisture in the phone.
This cause the phones power management to get fu up (SGS2 has a small battery inside of it, and that gets fu up). Only fix is replace hardware, but 9 of 10 times Samsung gives the fault to the customer. They say it has water damage and can't be fixed in warrenty...
I'm going to write a huge article about it, and I hope it will get published by a lot of site's soon. Phones he admitted having the problem: SGS1, SGS2 and SGSN.
I charged my GS2 2x by USB and it's discharged faster than by the sector
The USB power isn't enough for charge up the GS2 correctly
Are you guys suffering from rapid battery discharging, i have all of the above symptons but my battery drains within hours...I`ve even bought a brand new battery off ebay that is exacly the same issues... I`d like to send it back to O2 but i`ve rooted and flashed custom firmware...
I have 2 HD2's running android 2.3.5 using the CyanogenMod-7-09222011-Nightly-Desire[TyphooN_v3.6.5-MAGDLR build#GRJ90
My phone never has any issues, but my wifes phone has crappy signal. 2 bars to no bars to no network at all.
I looked at every setting on both phones and noticed her radio was an older version. Ah Ha! I said. Let me flash it with the same version I have and that will be fixed. NOPE.
My basband version is 15.42.50.11U_2.15.50.14
hers I forgot, I know it was a lot older.
So I downloaded the radio (same as what I'm using) and booted into the 3 color screen 2.08.HSPL. From there I connected her phone to my computer and ran "CustomRUU.exe" with the RUU_signed.nhb file.
It went to 100% and all seemed to be fine. It rebooted and I can look into the settings/about phone and now the baseband versions are identical.
But hers still has the crappy signal, most of the time.
I've downloaded older radios and tried them 4 different ones and all act the exact same way as hers did in the beggining.
Now I don't know what to do. I've even started from scratch. Using HD2 NAND toolkit wipedTask29, reinstallled MAGLDR v1.03 by Cotulla and HSPL.
Not sure if anyone needs anymore info to help me.
I've searched and searched and no one seems to have this issue.
Could it be a ROM? Did something not flash correctly?
I am a NOOB but have friends who walk me and taught me these things and even they are confused.
Thanks.
Turn off that better device (or only wifi), check does second works better.
Or replace places of devices.. maybe something disturbance signal.
At last.. maybe try other, older radio - newer not means best.
done that. Since I'm at working with one SIM card as I'm testing, my other (good) phone is turned off.
Also tried older radios.
I also just noticed that instead of "H" or "3G" or "E"(edge) i get a "G" for my data. Just to add to the other crazy stuff.
If you search in the android general section there is a post about how there are a few little connectors between the main board and the phone body that of the phone has been dropped or taken apart can lose their connection leading to poor reception. I'll see if I can locate it and post you a link.
And here you go, check it out.

I had the same exact problem with my phone. I researched it and finally found the answer here:
http://forum.xda-developers.com/showthread.php?t=1190180
It worked wonders.
Wow, Thanks so much, I will try that.
It's funny, before I read this I was messing with her phone and it fell backwards and the signal jumped up. Unfortunatly it didn't last long.
I also noticed the way she puts her phone in her back pocket!. She did this with her old iPhone (which is a lot more rigid) with no issues.
Now I'm guessing that she bent it to the point where as you have found that the contacts are not making good contact.
I'll try this fix and reply what I find.
Thanks a million again
steviie8, click the above link and try it for yourself, it really works ! I fixed mine in 15 mins and now my weak signal HD2 gets full bars, miracle has happened
It worked!!!
Thanks guys,
Unfortunately, I snapped the one contact off, I resoldered it worked fine.
Unfortunately, in the process of dismantling, I cracked the LCD.
I put everything back together and see a nice black circle in the corner.
I'm on my way to get the new part. So let that be a lesson to all of you, When they say the contacts are weak and easy to snap off, they mean it.
My problem from the LCD was do to not having the proper plastic tool to take the phone apart. Live and Learn.
Hi Everybody,
I believe that I am now in serious trouble with my Motorola Defy. I have tried to look everywhere today to find a similar problem to what I am experiencing, and although I can find all the problems, I can't find anyone which has happened like this. It would be so great if someone could help me. I am so so desperate and in total panic right now. I need this phone to work which I had bought in Germany (where my home base is set up) but I am currently working in Estonia where salary really does not allow me to just go out and buy a new one - not even a cheap 20€ phone.
I originally bought the phone about 1 1/2 years ago with Android 2.1. After about 6 months I did the official update to Android 2.2. This is where a few things started to go wrong. Google maps would crash the phone so that I would have to take the battery out to restart it. The camera didn't work properly, and not at all with the flash, and the phone would quite often restart itself. I could however live with all this and just accepted it as I didn't want to do anything to make it worse - I trust myself 100% with computers and there isn't much that I can't do with them. But with phones, that's where I have to put my hands up as I really don't trust myself to do anything because of the fear of bricking one.
Anyway, today as I was using the phone after taking a few pictures the phone had frozen, so as always I took the battery out and turned it on again, when it loaded up and as soon after I put my pin and unlock number in, it restart itself, So I again I put my pin and unlock number in, and it restarted itself. After this I couldn't even put my pin number in.
I then did went into Bootloader to do a wipe and restore, This however, after taking two hours and just watching the yellow dots move along, was clear to me that this also wasn't working. After coming home from work I then copied the instructions found I think in the Beginners Defy Guide on this site for using RSD Lite and an SBF File. This then failed and in Bootloader it also then said Corrupt.
So I then started to watch a video on youtube for a complete guide from unbricking to installing CM10 (something I wanted to do the whole time and never trusted myself). Meanwhile, whilst everything was downloading, although the phone still had about 60% battery, I thought I would plug it in just to charge it for a bit, this however also did not work but I left it in just in case it was working.
After everything was finished downloading, I unplugged the phone from the wall and now it won't even turn on,, neither in Bootloader, or the screen. It does NOTHING! :crying::crying:
When I plug it into the computer the little white led light comes on (top left of the phone) and the computer makes the sound that something is plugged in. This is also recognised my RSD Lite, however once a file has been created it cannot be flashed. It's like the phone is there, but it isn't.
I am really desperate to get this working as I really need this phone for work, and like I said just cannot afford to run and buy anything.
I'm very sorry if I have posted this in a wrong area, but I honestly did try to find something. I just don't understand how plugging it in to charge can stop it from not even opening bootloader, It's like it's got a mind of it's own.
Thank you very very much for reading, and I apologise that it's so long,
Best Wishes,
Steve
To get into the bootloader , keep the volume up button pressed and then press the power button. Is this what you tried to do?
And I didn't get the part where you wiped through the bootloader. As far as I know there is no option there. Do you mean the stock recovery?( The yellow dots are there in the stock recovery)

Check out this link all the best :good:
Hello all; apologies in advance if this is retreading old ground, but I couldn't find anything about this on the forum as is.
So, while taking some video the other night, my Razr M (all recent software/OS updates, stock software + commercial apps , no flashed ROM/no root/hell, I wasn't even using GoLauncher anymore) decided to freak out on me. By the end of the night, it got itself stuck on booting, and by the next day, it's more or less bricked. Called, got my replacement phone from Verizon, but before I ship this off, figured I'd plug it into the PC and see if there was anything I could do to salvage data -- most things are backed up, but the video/things from that day obviously aren't.
So, no screen. When I plug in, I get the little green light intermittently. For fun, I tried getting to a boot screen (Vol down/Vol up/Power), and now I have this fun thing where my PC tells me it's installed "Fastboot SMQ S" drivers, and is "searching preconfigured folder drivers". Every few seconds, the phone's light will be green, a few seconds later, it will go off. Likewise, my device manager keeps trying to recognize a Human Interface Device, and now and then Windows tells me a connected device has failed. (Once every now and again it tells me it can't recognize it, for about a half second.)
I should note that at no time during any of this does the screen on the phone itself give me any sort of image or feedback.
This leads me to think there's still something inside the phone fighting to work -- as stated, I don't need it to get back to functionality per se, but if there's enough left to work with to at least pull data off of it before it clinks out, I'd be quite happy.
This seemed like a question for the XDA folks, even though it isn't mod/dev related, because you guys are usually the forum I read when I have questions, as you all seem to really know the insides of the phones and systems. If there is a better forum/place for asking this question, please just let me know. I'd be grateful for any sort of advice/insight you may have.
Thank you, and have a great afternoon!
p.s. I assume, based on other similar threads, that the whole "stealthily open the case, yank out of the flash and kitbash it into my pc while somehow not voiding the warranty" route is unfeasable/undoable. If this is not the case, I'm game for that. I'm not a phone dev, but I've seen the inside of an electronic device or ten in my time, so I might be able to pull it off.
Hi, I have a LG K20 Plus. I currently can't turn the phone on, so I don't have much software information to give you. The phone was bought at T-Mobile (Metro by T-Mobile) and I had a SafeLink sim card and a 16 gb micro sd card inserted when the issue started. I have since removed both. It says Qualcomm snapdragon on the screen when it starts. It was also rooted and the bootloader is unlocked.
I broke the screen on my phone and I decided to do the repair myself. I have done about 7 or 8 screen replacements and I actually did this phone a year ago with no issues, so I felt I could manage this one as well. I bought an entire display (from ebay) and switched it out with no problems. Initially it worked great! I used it for a few days before realizing that I had no sound. I opened it back up and noticed the loud speaker had fallen out. I found it, put it back in, reassembled it as I normally do and turned it on.
NOTE: when I was reassembling it the second time, I actually tried to put a screw in a hole that wasn't a screw hole. I used a light to normal amount of pressure but I didn't force it. I think it's the hole where the moisture detector is. Picture #1
I turned it on and right after the logo screen I got a message that said "High temperature detected Powering off for your safety" and it immediately shut off. The phone does appear to charge normally but it won't stay on. I did a factory reset (I'm not sure if it's still rooted but the bootloader is still unlocked). I also switched back to the old (broken) display just to check if that would work. I couldn't see any difference in the shielding but I switched them just to be sure. I bought a new battery and installed it. I took a q-tip and 95% Isopropyl Alcohol and cleaned pretty much the entire motherboard, paying special attention to the battery connections. After each one of these things, I tried to start it with the same error message immediately upon start up.
NOTE: At no point has the phone every physically felt hot or even warm. I don't think it's on long enough for it to get hot. But something is wrong and I have no idea what it is. I, literally, took the phone apart, put in the speaker and put it back together in less than 5 minutes. Could it be I just bumped something and knocked it loose?
I searched for any information I could find both here and with google but there is next to no information on the LG K20 Plus. I did find some information on the LG V20 that had overheating issues, and that has been all the luck I've had. I watched several videos and it seems the solution is to apply thermal paste. But my phone doesn't have any evidence that thermal paste was ever on it. I went and bought some but I have no idea where exactly to put it or even if it's needed. Most videos showed people using some kind of aluminum foil but I'm not sure if that is safe. I have several old phone laying around and I managed to get some of the silver tape and a copper square thing but, again, my phone did not have these things to begin with. I don't want to start adding things only to make it worse.
There is a slight difference of the tape that is on my phone now (the display I just bought) as compared to the old one (broken display). Picture #2 Again, I have no idea if that means anything but I thought it worth mentioning. Picture #3 is how it looks now as if I were going to put it back together. Picture #4 is the part (don't know name) where the videos show to apply the thermal paste and the shielding.
I'm really at a loss as to what to do next and I can't really afford to take it in to have it repaired before next month. If anybody has any insight or answers as to what happened, I'd be very grateful for your help. I'm sorry for the long post. I just wanted to tell you everything I have done in detail. Thank you
If you're using Kernel Auditor or any other kernel adjustment simply reset to default and use only ondemand or interactive. There's also options for the thermal portion of the kernel, don't mess with those. If VCC or another thermal option was checked off turn it back on. Putting the GPS to the moderate setting (the one below high accuracy) will keep the temps down as well. Are you using a custom ROM? If you're on Discord you can feel free to message me SCOPE★ BRΞΛD #8460 . I am only offering that so we can get this resolved quickly for you, just copy and paste since I use special characters.
Omgosh, thank you so much for taking the time to respond! Although I'm sure everything you are saying is very smart, I have absolutely no idea what you're saying. I'll do my best to try and answer you. I don't know what SCOPE is or how to send a message there. I don't think I'm using any thing for the "kernal". Also, I don't know what VCC or Discord is. As far as turning off setting for GPS or any other app, the phone will not stay on. I get about 1 sec after the logo when it boots up, then the error message about overheating and it immediately shuts off. I did a factory reset so everything should be good to go as far as apps. I don't think I'm using a custom ROM. The only thing I did was install TWRP, unlocked the bootloader and rooted the phone a year ago but nothing since then. As I stated earlier, this happened right after I did a display repair. Is there something on the MOBO that can get bumped that will make your phone get hot or send a overheating error. My phone doesn't show any sign that there was ever thermal paste on it prior but should I add some now. Will that help?
Update... Now the phone does not power on at all. When I plug it in to charge it I get an error that says "Device temperature is too high or low. Please move to another place to charge. I wonder where you went. I googled SCOPE so I could sign up to message you like you asked me to but nothing but definitions came up. I know I'm out of my league here. You guys all talk so technical. I didn't understand one thing the person asked me for. I know it's rare to get a response as quickly as I did and I was so happy to see someone had responded. Now, I just feel stupid and defeated. I thought this site was inexperienced with cell phones friendly. I'm just trying to get help so I don't have to go out and buy another phone again. Can someone refer me to a site that is more directed toward people who don't know much about the technical side of cell phones... please! Again, thank you for your time.

Hey, I just wanted to say sorry this happened to you. The same thing happened to me. My LG K20 Plus, no matter what button combinations I push and for how long I hold them, will not turn on or go into download mode. Plugging it in to a charger or PC does nothing either. Before it got to this state, I got the infamous green screen of death/Demigod crash handler (google this--it's a known issue with some models of LG phones and it happens when they overheat). It's definitely a hardware/build issue, and especially since this issue keeps the phone from turning on or connecting to a computer, I don't see a workable fix short of buying a new phone, unfortunately. Again, I'm in the same boat so I'm not happy about it either. I would say XDA is by far the best site to find a fix to this sort of problem, so if no one here has any suggestions on how to fix it, I think you (we) may be out of luck.
Thank you for letting me know. I'm not sure of some of what you said but I did catch the bottom line. Basically, just hold onto the phone until someone here comes up with a fix or workaround? I have a question for you. Did your problem start after you did some kind of repair? I'm wondering if I bumped something on the mobo to make it give a false overheating error. Do you happen to know where that sensor might be located? Sorry you are having problems to. It really stinks when your phone breaks and no matter how much time and energy you put it to figuring out the problem to fix it, there just isn't any good answers out there. I wish you lots of luck and if you figure anything out, please update here so I can try it too.
You need a whole new phone.
That or you're gonna have to replace the hardware
