Phone stuck on USB/charging... very weird

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...

Galaxy S2 refuses to charge and start

Hi folks,
So here's the deal: my Samsung Galaxy S2 suddenly refused to charge and became very hot. I turned it off, took out the battery and it won't accept any new juice.
After I turned it off, it won't even start. So I have a battery that cannot be charged, and a Galaxy S2 that refuses to start. When connected, a battery icon with a triangle is displayed. Any ideas?
Should I try to get a new battery or is there any trick for this? I'd rather not send it away.
Cheers

It's pretty similar to this issue:
http://forum.xda-developers.com/showthread.php?t=1114016

No one knows, huh? That doesn't bode well...

This is identical to my problem. To restart your phone. Take the battery out. Plug the phone in, wait a few seconds then put the battery back in. Imediately, press and hold the power button. The usb charging circuit is damaged. It needs a repair but will probably be replaced. A few of us had this problem.

Thanks for your reply! If that's the case, it's the first phone I've ever had since 1998 that has broken down.
I tried the method of starting it that you suggested, but it didn't work. I guess I have to send it back. Even though it's a great phone in other regards, I won't be buying a Samsung again.

Hm, it suddenly decided to start again for some reason and now I can charge the device while it's turned off. But when I try to charge it when it's turned on, it just becomes super hot and loses power instead of gaining it.
Can it be a software issue? It's really weird, since my SGS2 can be charged while it's turned off but not when booted.
Cheers

Hi there i have the same problem with mine too, do you flash any rom in it or kernel?
I guess its a problem with the kernel or rom you have flashed, mine have the same problem, but you can put it charging in the usb cable in the computer and let it stay there for a whyle, then you have to try to boot it up by using the 3 keys (power+home+vol up) it will boot in recovery mode then you ask it to reeboot and install an updated kernel or reflash the rom, while the device is on, do not put it off, because if you do it you will have the same problem to put it on again, but when its on it charges normally.
I have changed mine for a new one but the problem i am sure it was the things i flashed it. I was using another kernel to install and root the device and again put the original stock kernel in the device to get rid of the yellow triangle, but that came up with that problem. I even dowloaded root explorer in order to reset the battery status bin (you have to be rooted to do this) and reboot the phone but with no avail. The other you have to do this is install CWM MANAGER V1.80 MY KERNEL CF-ROOT 4.0 MY ANDROID VERSION 2.3.3 BASEBAND i9100UHKE2 and now note this the stock kernel was the uhke4 but the kernel i put it it is [email protected]#2 COMPILATION NUMBER: GINGERBREAD.UHKE4
Note: i dont know if it will work for you, i am using a stock rom from samsung. If you do not flash anything its better to return the device or even you have flashed it buy a usb jig and reset the counter and find for the repair, they have to fix that for you.
I hope that have provided you some help.
best regards

Happend to me after installing an over clock thing i uninstalled it and it worked fine

thats what i have said but try to update the kernel and try it mine was uhke4 and now im using xwke7 rooted and worked like a charm all working perfect now, just the problem with the yellow triangle on boot, besides that nothing else even it improved battery life and gps works even better .
hope i have been usefull.

@OP- Go to Service center. Don't waste your time by doing this and that. I am having the same problem, though freak me did some experiment with it. You will get replacement/repaired as it's inside warranty very much.
And don't try any freak method with the new one.
Regards.

Man, better sending your phone to service center before damaging it more.

Have you got the replacement?????????????

Thanks for all the replies. Like I mentioned earlier, I'd rather not send my Galaxy S2 away to a service center, even though there obviously is something wrong with it. I'd be without it for weeks and my S2 is like the Ring for Gollum
I can still charge it now when the device is turned off. But whenever I try to charge it while it's turned on, it just becomes super hot and loses power. I'm starting to think that the battery is damaged, and not the actual device.
Anyway, I just rooted it... Couldn't resist, so I bet I can't even send it for service now without trying to unroot the bugger

so if we take it that anything thats not needed is a waste of time ? like being here ? well, that first line about service center just make me think . Why would the OP post here, because he's not going to a service center..looks like it. it could have been he would though. I just dont like that advice myself. here, they wouldn't do nuttin for me if i brought the phone.
I knew a few that a few years back had phones for repair, they don't replace them, they do some awful repair, and it doesnt work afterwards. second, if after using a phone a whole lot I wouldn't trust them providers with it for weeks . What I mean is for some, its like sending a diary for inspection and approval. Not being VIP nor secret, but ya pwn biznizis ya pwn bizniz.
there must be something to it with the software/firmware, as mentioned a bit below

well, I tried cyanogenmod, and whatever kernel/modem/baseband etc... so! it is like version ki8+ki4+ki3 if that makes any sense . brand new sgs2 gt-i9100 int. version in white. battery ran down to 6%, microUSB thru PC or charger didnt do nuttin, then i turned it off, and looks like its charing. must be a BUG!!
gotta fix that. or get a bigger battery..and then fix that
any1 else having problems with cyanogenmod ? probably im running a wrong kernel, or a wrong 'something'.
does cf-root conflict with rom manager, if so, what to do anyway ? what rom/kernel version should one use with cyanogenmod 7.1.0 RC1 ? how many 'roms' are prone for this no-charge-issue ? time for another rom maybe? cm7rc1 report version 2.3.7
I can also confirm that the phone does get a little warmer during the no-charge-issue. Would want to get one of those colored alu covers, but not sure it would do much better in coming cold winter.
whatever is causing the issue, thats really stupid! what kind of problem to have..put that on the messenger machine 'my phone has gone off to charging at the moment, it'll be back later'.
questions is - what to flash ?

My Samsung Galaxy S stopped responding so had a replacement sent over - Orange replaced it with a S2 - however I struggled with it for hours before ordering a second replacement - charged on first go then wouldn't charge again - so again fiddled about for ages. Eventually took SD card out and now it works fine bloody annoying.

2 phone in 2 weeks the yellow triangle
The first SGS2 I got the second time I went to charge it the Yellow Triangle with the Astrix symbol came up with in 2 weeks the batter was over heating and only holding a charge for 4 hours. I exchanged for a new SGS2 and it has been 3 days the same Yellow Triangle with astrix has come up. I am going to get my money back and use my old phone which is unfortunate cause I really like the SGS2. What is the issue with this? is this really a connection issue?

Take the phone back and get a replacement as it a very good handset.

Samsung Say's
This Yellow Triangle with the exclamation point in it is suppose to show up when the battery is completely dead and only when completely dead until the phone has enough juice to be turned on then it goes away. It should not be related to any other problem with the phone. If you get the yellow triangle when you still have power to the phone then you need to take it in. This will lead to over heating the battery and trust me the phone gets extremely hot. Then you will not be able to charge the phone.
If the battery is hot take it in.
If the Yellow triangle only shows up when the battery in completely dead and then goes away a little after you charge it your phone is fine.
This is what Samsung and it's tech support said to me.

Random Power Off & Boot Loop Galaxy S4 GT-I9505

Hi,
Not sure what is happening to my phone. I have had stock 4.2.2 rooted with CF auto root for months and had no problems. A few weeks ago my phone started to randomly shut down, not properly just complete power off in an instant. It would then start to reboot and get to the Samsung S4 logo screen before powering off again and trying to reboot and then gets stuck in a constant loop. At first I was able to just reinstall CF root with Odin and it would start up OK. I could also get it to start by re-installing Philz recovery.
Now though, that doesn't work so this morning I installed JB 4.3 I9505XXUEMK8-PRE-ROOTED-KNOX-FREE-ODEX-FULL.tar.MD5 and it says that it is rooted and everything seems to be OK but after an hour or so it has started to randomly shut down again. If I attempt to go into recovery (stock) and clear the cache partition it will reboot normally and run for a while until I use an app and do it again. Am I doing something wrong here or is my phone just knackered?

Maybe is coz the RAM is overloaded. Take a look in:
- Press HOME button for 2 secs
- U will see 3 icons in the bottom. Click on the "cheese"
- Tab "RAM"
- If ur phone use more of 1 GB of RAM for run ur apps maybe will be time of delete bloatware

I had the same problem in GT-I9500, I had to get it repaired in a service center.
There was a problem with mother board to charger port connection..
Hope it helps you!

If u wanna try to recover some RAM u can delete some bloatware that u dont use. Tc with what u delete. I let u some info about if u wanna try -> HERE

I have this problem, I swear it is because of the dodgy battery. (I have the BD battery)
When I plug it in to charge all works again properly.
Last night my battery was showing in the high 60's the phone went off. When I put charger in the battery was at 3%!
Very annoying, going to take to Geek Squad tonight and see if they wil lreplace battery. Guy here at work has same phone, different battery derial number and no problems at all.
Hopefully they will change the battery, I don't have any paperwork with me but the phone is obviously within the 1 year warrenty.

Interesting. I have noticed a couple of times when I look at the battery stats that it has drained from say 90% to 3% in less than 1min, just a verticle line. When I plug it in to charge it says that it's at 90% or whatever it was. Other times it needs charging and is almost dead. It's as though it has shorted out. I wonder if that is the problem here.

Thanks for that. It's quite a list. I'll go through it and remove the ones i think i can do without and see how it goes.

Same Issue
I have the same problem with my I9505
- It shuts down randomly (sometimes you see a few seconds in advance that your connection to the mobile antennas disconnects), when you look at it, in the middle of a phonecall, ... whenever it's nog plugged in to the power of external battery
- It's almost impossible to get it powered on again (gets stuck in a loop of rebooting: most times at the Samsung logo or after it's on for a few seconds), unless you connect your charger that is connected to the powergrid or external battery
- sometimes it resets the phonelanguage to default (so in stead of for example Dutch, everything is in English again)
I just cleared the cache and removed some programs...
Fingers crossed
--> I'll give an update if anything changes

I've tried that as well. Didn't work. The problem you describe is exactly the problem I have. I have ordered another battery but I don't think it's that. I'll let you know if it is. I hadn't noticed that it always boots OK if it is plugged into the mains. Wish I knew what was causing the problems.

Random Shutdown and boot loop
So I think I am finally getting somewhere. I took this screenshot straight after it shut down and got stuck in a boot loop. So I plugged it into the mains and it started OK. The battery just gives up when i stress the device with a hungry app or when booting which causes a heavy drain on the on the power even when its got a healthy charge. Got a new battery on order. Take a look at the screenshot. You can see the battery instantaneously drops to zero charge until it's re-booted on the mains.:laugh:

in the list I forgot to mention that the known wifi's are also wiped. --> you have to connect to them again...

I too am having this exact problem; I'm glad to hear it is not only me, not that it helps any of us.
I posted in another thread, but the symptoms everyone here are describing are exactly what I am seeing:
- Sudden battery drop from anything (it's happened to me before about 5 minutes after unplugging from the wall socket) to zero; then phone goes into a loop unless I plug it back into the mains socket
- When plugging into the mains socket with this issue, sometimes the battery is empty and sometimes it shoots straight back up to where it was
- Plants Vs Zombies 2 is the sure-fire way for me to reproduce this issue
- examined logs (although not sure if the right one) using CatLog; nothing obvious (in fact the last line on one of the logs is litterally cut halfway through)
- Wifi connection details lost occasionally
I have reflashed about 4 other (4.3) ROMs (and I tried a 4.4 GE one too) and they all seem to do the same; I am wondering if it is something to do with the non-Knox modems required to flash the 4.3 ROMs as I don't think I had this problem before updating to 4.3. I don't have the time or patience to revert back to a 4.2 ROM to test this though.
I can go for a couple of days without this happening, but fire up PvZ2 and here we go again.
I too have a new battery on order (allegedly genuine from a well-known auction site), so I will update this thread when that arrives to see if it makes any difference.

I don't like this post for one reason.... it means that the problem I am facing won't solve with a format and a new fresh flash... :crying:
I was spending some time on XDA searching for a good stable firmware to flash because I am having your exactly same issues on my phone... I just tought my phone got a bit messy because I have 130 apps installed and a lot of stuff on it.. so I was just thinking of solving all my problems with a new rom... but then I found this 3d...
So you are telling me that my problem won't get solved so easely? How am I going to deal with a Phone that randomly shuts up??? I need my phone and over the last week it got always worse.. first it shut up at about 5pm.. (at ca 15% charge) then at 3pm and 50% charge... today it shut up at 11am and 80% charge... soon I won't be able to use my phone at all!!
I'm happy I backed up all my data today, but it still doesn't solve my problem since I really need my phone... :crying:
This evening I'm going to flash anyway... let's see what happens..
PS I own a GT-I9505 with 4.2.2 stock rom (root)

Random Shutdown and boot loop
Sorry to hear there's a few more out there with the same problem that I am having. AhHm... Sorry, WAS having. I tried re-flashing all sorts of ROMS from 4.2.2 to Echoe KitKat 4.4, flashed CF Root, reinstalled philz touch recovery god knows how many times all to no avail. I now know that it is nothing to do with your ROM or phone setup. It's Samsungs crappy battery. As soon as I put in my new battery problems solved. I have been running multi-window apps whilst having FB on in the background and watching a film all at the same time. If this was gonna crash it would have done by now.
Problem solved. Don't buy the cheap SPB £9.99 one on ebay it has lots of bad reviews. I got this one with no problems:

Hope this helps and don't forget the thanks meter.

I'm glad you solved.. this means there could be a solution to my problem... in any case the fact that alla batteries here seem to fail in the same week is really strange!!
And the thing I hate most is that a 500€ phone shouldn't be dying after just some months!

After having spent some time googling around.. I found a solution... well, not exactly a solution... let's say I found the core of the problem...
I found some very interesting posts on the misfuncion on all Samsung S4 Batteries Made and Produced in China with SN starting with BD....
And guess what? my battery corresponds!!
If you look at the battery you will notice that it is a little "bumped" and not perfectly flat...
Here in Italy many users went to samsung customer service and got the battery replaced!
Tomorrow I will check to see if I can get a new battery... for now I'm happy to know exactly what to do in order to get my phone working again!

Samsung Batteries beggining with BD.

Yeah I found that out tonight also. I called samsung earlier today and they said if it is less than 2 years old they will repair it and I should send it to them. I have flashed so many ROMS since I purchased it last year and one or two with Knox which as we know registers that it has had a custom download which voids the warrantee so I thought it would be a waste of time sending it to them. Also I need my phone for work so it was easier to purchase a new battery.

Bad samsung batteries

Hi,
Do you have a link to the info? was it on an official samsung site?

A3000 won't start or flash

This morning my A3000 started up then it shut down. Now when connected to a charger it only shows the LCD backlight no other operation. Tried to flash it but it won't stay on for more than 3 seconds, my XP laptop sees it then it disappears . Tried the reset button, tried disconnecting the battery for 10 minutes, next step is the hammer unless you can help it :fingers-crossed: only joking I would be lost without my A3000.

I know it's really annoying in such posts to say "Same problem here"..
but there is nothing I can do about it, I really have the same problem...! :S
even more, ! don't have an NVram backup so I lost my chance for formatting..

Hi, I had an idea, I have checked the battery voltage which is reading 3.03v (should be 3.7v) and has very low current so I have ordered a new battery today. I am hoping it is just that it can't start due to lack of power.

That will most likely work, I think mine would even be lower than that. but isn't there a way to charge it to that level?

Try to uninstall with wipe (ccleaner etc)+reboot & reinstall your driver from ur computer without connecting ur tab.
Then run spflashtool by download or upgrade mode (anyway which work) for a minute wait time.
The proper quick drivers & latest stock rom can be found at @azam436 thread on page 1-4, check it out.
If u ever flash stock rom by spflashtool, your nvram should be automatically backed up & will restored (cmiimw). Good luck.

All that has been tried of course, we are hardcore users
I tend to believe in @RayA3000 theory, waiting for his follow up about changing the battery, giving that my battery has gone really weak before the accident that I need to charge two times a day or just leave it connected to charger so I can be ready to go any time..

EUREKA - my new battery arrived today and my A3000 started up as usual, I'm chuffed
I have worked with batteries for years (we do camera repairs) and have found some batteries can just loose the will to live, no current. At £17.00 it was a cheap fix.

Dead i9505

Guys, Need your help. You are my last hope !
Just bought an i9505 to a guy, via internet... I know it's risky... The guy was saying the phone got stuck after he had a power cut (his PC shut down) during a Kies update., but that the phone was able to go to download mode.
So I thought it would be easy to flash.
The bad surprise was when I received the phone : nothing happens, no sign of life. No sign when pluging the charger, no sign when trying to boot whatever mode I select, no vibration, no sound, no nothing... I even tried a Jig USB dongle that I had purchased a few years ago for my i9000 : nothing.
I contacted the seller who pretends I broke it as he checked again the download mode before sending me the phone.
I tend to believe he is saying the truth as he could simply have not responded.
Is there any experiment I should do ? I read that getting the battery off and pressing Power for 30 sec might help... Did not work either...
Any other ideas ???
Thanks
Edit: oops sorry, this thread should have been created in the "Q&A, Help and Troubleshooting" section... Moderator... could you please move it there ? Sorry...

Plug it in to the wall charger for a while and see if any thing happens, I've had a battery dead flat before and it took a couple of minutes before it started charging.

Thanks ph0n3n3rd. Trying right now, but not real hope as I have another S4 with a fully charged battery which I already tried with no success.
I also have tried charging the original battery for hours today both from my laptop and from and external battery (branded Anker) which usually charges even faster than the wall charger...
Also one of the first things I tried when I received the phone without being able to boot it was to try the other way : the new phone's battery in the old S4. And it booted. The new phone's battery was about 40%...

Yep... I read a RIFF box could help... Do you know what it is ?
BTW, the wall charger did not help (i got it plugged for about 10 minutes).

type in google some like "repair boot i9505 via sd card"

If the pc can recognize the phone then this might be useful.

Hi GDReaper, thanks for the link. I had actually seen it yesterday. I have installed (this was not easy as I was getting an error when try to install the .inf files) the QHUSB drivers... in the hope that this would help the PC not only recognize, but detect (!) the phone. Indeed the phone is not even detected by windows : no sound, no "drivver installation message", nothing that I can see in the Device Manager. And the phone too does not show any sign of connection to the PC...
THe guy who sold me this phone keeps telling me he could go to download mode just before sending it to me. He is even getting pissed off and pretends i'm a liar...

Unless it somehow got damaged during transport, then he is the one who is most probably lying.
You will have to take it in for service if you can't get a refund. I doubt it can be fixed without any specialized equipment.

Hi bes1de, thanks. I can only find this one : http://forum.gsmhosting.com/vbb/f777/hot-hot-easy-repair-boot-samsung-s4-i9500-via-sd-card-1693343/ for now but this is for i9500.
BTW... I realize the phone does not seem to be an i9505 but an i9515 ! I got confused because of this : View attachment 3654348
As you can see, the sticker shows i9515 but the "housing" is i9505...
The SIM card reader also shows i9505 : View attachment 3654337
And... the charge flex cable shows i9500 (yet another S4 model !) : View attachment 3654338
Do you think Samsung uses parts from different phones like that ? Or that the seller kind of rebuilt a "phone" from various parts found here and there ?
I'd like to be able to test the parts of this dead phone to see if I can sell it as parts.
I was thinking to tear down my own personal S4 (i9505 perfectly working) and use its motherboard to test the dead phone's screen.
I read that the LCD is different...
Do you think I might break my i9505 motherboard trying to connect it to the i9515 display ?...
Edit: OK I did it ! Installed my personal S4 motherboard into the dead one in order to check the display, the buttons (incl. touch ones) and the USB/charge port : all is fine. The PC detects ad recognizes it, so the USB connector and its flex cable are fine.
I could now swap the cameras, the proximity sensor, the SIM and SDcard readers and see if they are OK...
Edit 2: Loud speaker works fine too.
Thanks and regards !

Edit: Anyone used the SBoot clip here ?
As far as I understand it only works with Exynos phones, so not for my i9515. Any information about that ?
Thanks
