I need some help diagnosing a dead S2 - Galaxy S II Q&A, Help & Troubleshooting

Hello all.
I'm trying to fix my fathers faulty s2. Here is the story so far;
The device is about 15 months old and started to develop a a fault after 13 months. It would keep going into car mode and it woundnl't except a charge. Cleaning the usb port seemed to only be a short term fix. A few weeks after this the phone died and wouldn't power on.
It was sent back to Vodafone, where they told me it was out of warranty and would cost 120 euro to repair even though it was well within warranty. After this it went back to Samsung where they reported water damage. I decided to have a look at it myself and I replaced the usb port, but it didn't help at all. I've tried a battery from a nexus but there was still nothing.
There is no sound when I plug into my PC or even a power vibration.
It was on stock firmwire so it wasn't a case of bad flash.
I have attached a few pictures. Does it look like water damage to you? If so, what would you suggest replacing?
Thanks,
Niall

Too late, already copied it down :silly: :good:

Whoops.. Edited

Given you've already replaced the USB port (I presume you changed the flex cable ?) in the first instance, it's probably the associated circuitry. I imagine they'd probably replace the MB rather than fiddle around with individual components.
You could do that I guess (get one from a 'donor' phone). I doubt you've got any comeback if they say water damage, you could spend money getting your own reports/opinions saying its not, but that's going to cost you a lot more than $120. It should boil down to what the cheapest option is. At this stage, replacing the board yourself is cheapest, then not arguing/paying them to do it, followed by arguing the point with them & trying to get them to do it for free (which they won't).

[Q] Atrix not powering on

My atrix won't power on (dropped in water); I have had it in dried rice, placed in a zip bag, and sun dried....before all that I immediately removed the battery and shook out whatever water i could. I've waited a full day but still no luck; if I remove the battery and plug in to PC with battery removed I get green LED but other than that I get nothing (for example if I switch to wall charger immediately the LED goes out). If at worst case I need a replacement, how difficult would it be to have this done without the AT&T purchase receipt (I'm not an AT&T customer)? I purchased the item on eBay a little over a month ago. I've read in forums to unroot before attempting return but that's not gonna happen (lol). My girlfriend hates that I even got an atrix so she's kinda happy this happened...a little off topic here, but I really love my atrix so can someone please help me out?!

Well, no help cuz no solution is available. Your phone is screwed and if it fell into water, the water seals must be screwed up as well and guarantee is void.
Think about it
Well the green LED comes on when plugged into USB like I said...but other than that nothing...I can't find the OEM charger adapter of all the times to be lost. I guess since other threads were successful in revival I would have hoped I would get lucky. Thank you for your reply.
They will know it's been in water by the sensors. They will also know you didn't buy from them. Best bet is insurance if you have it, but I think you are out of luck.
Beamed in from WinBorg 4G via XDA Premium app
i jumped in the river about 2 weeks ago and completely forgot i had my atrix in my pocket. i would say it was about a good 5 mins underwater. Water damage sign appeared on atrix as well as battery. (red dot). i did the rice thing too..but nothing. unless you're insured..which i was..theres nothing you can do. sorry for your loss.
Does anyone have a general idea of how much it would cost to have the board replaced then?

Is that USD? H%*LY *^&%!! But that doesn't look like the board that I've seen
funny. i looked up the same info as you are. That link is what a friend of mine sent me. so im not to sure. maybe someone here with better knowledge can help you out.

Actually I sat and thought about it and there's the fingerprint and camera to also take into consideration, as well has other functionalities just didn't post. I'm in between studying Windows Server 2008 , watching TV, and just randomly doing other things. Thanks to you all for your help though. I may just try to find an atrix with just a broken screen or just forget about it all together. I've only had the phone for 3 weeks but stuff happens, consider it $500 down the drain .
Disassemble it, take a look at it, remove the corrosion manually. Use a heatgun on the components, but dont overheat it. Afterwards put together and check if battery still has power with a multimeter. Reassemble and plug into wall charger. See what happens

I say this is your best bet. Try this, or get someone with some electronics knowledge to take a look.
It beats just tossing it.
Either that or put it up on ebay and try to recoup some money. someone with a broken screen, or camera might want to buy it for parts.

[Q] USB hardware problems, I think

SG2, bought in some shop in China, now live in Thailand, Revo HDv6, various kernels depending on my mood.
I've read about this problem in a few different forums, but not here - THE forum for android...
I was getting reboots after I turned the phone off (it won''t stay off!) After some research I decided it was some **** in the USB port so I gave it a good brushing and fixed the problem
But now it's back and the brush won't fix it
Evidently the SG2 is sensitive to shorts across the pins...
Now it won't even turn on unless I have it plugged in - I get some battery overheating warning at boot (with both batteries) even though it is obviously not overheated.
However, once I turn it on while (any) plug is in the port, it runs fine - plugged or unplugged.
OH!!! apart from crap battery life now, I lose 25-60% overnight, without any data, wi-fi or other activity.
I've done lots of wipes and reinstalls of different ROMs, kernels, wipe cache, battery stats etc but to no avail...
I guess it's time to bite the bullet and take it in to some Thai repair shop.... Hmmm. Dangerous...
Any stunning ideas that make me happy???
Maybe a cotton bud just moist (not wet) with isopropyl alcohol.
this happened to me when i got my SGS2 usb port wet... and the problem is obviously hardware problem.. so the only 100% sure fix is replacing it... you have 2 choices here
first: buy off samsung official usb connector for SGS2 and replace it (video guide in youtube)
second: send it to repair shop/samsung retail seller to fix it.. and if i read it correctly and understand it correctly.. you cant get warranty of it because you bought it from china and is now in thailand right? so.... if you go to samsung retail seller it will cost minimum 30 euro (sorry i only know the price for europe) and depending on what they need to do it may increase to 150 euro
so... if you choose the second option.. be ready for high prices...

Thanks! It gives me a ballpark figure and a solution. Yes, I'd decided it was hardware.
I'll try the IPA, then take it apart and take a look with a magnifying glass, might be a wee flaw I can scratch out between connectors... then, if I f*** it up, I can replace the port.
I can call them plans A, B, and C haha.

[Q] Battery problems after water damage

I am having a problem after my phone was dropped in water. The phone is now fully dry but I am having battery issues. It seems that the phone believes the battery to be empty all the time. I can charge it whilst the phone is off until it states it is at 100% but as soon as i turn it on it says the battery is at 0% and turns off even whilst plugged in.
I have flashed a few different roms to see if the software had any bearing on it. The only difference I got was with CM 10.1 I was able to run the phone whilst it was plugged in but as soon as I unplugged it died.
I have tried the battery in other phones and it works fine and I have tried batteries from other phones (ones that I know are fine) and it says they are empty.
I did have one case when the phone came on and stayed. The battery level stuck at about 70% and never decreased over 24 hours. As soon as I rebooted it it said it was empty.
To me it seems like the bit of hardware that checks the battery level is failing. I have opened up the phone and given it a clean but no joy.
Any Ideas?
Yes since sensitive electronic components dont seem to mix well with water youll have to replace them.
Start with the usb board,then maybe motherboard if nothings changed.
Can anyone point out on the boards which bits are responsible for power management.
Also where would I be able to get replacement boards from?
TheUnderling posted a link to the service manual a week or so ago, search through his recent posts to find it. That has schematics/parts lists in it.
Re: getting another board, your best bet is to find a screen damaged phone on eBay or similar, Samsung aren't in the business of selling just motherboards (they'll charge you maybe half of what a new phone would cost to replace it).
You could see if Kevin Costner is going to make Waterworld 2,then he could maybe buy it off you.
You can get a new s2 now for £199.99 from Orange.

Not funny and not useful
Sorry,I shouldnt make jokes about it.What to do is take it to the man from atlantis and get a quote for a repair.
I don't mind you making jokes actually. It means you keep bumping my question to the top of the boards and then maybe someone who actually is helpful may help me out.
You got your help. The motherboard (at the very least) is cactus. And maybe other components. What else are you hoping for anyone else to tell you ? You dropped the phone in water, think about it. Ain't rocket surgery.

Hes got to start "splashing" the cash on a battery>usb board for starters.
And whos to say it aint going to end up in water again.
Best to sell the phone on and hope a mug buys it.
I guess I was juts hoping for more positive suggestions rather than sarcastic comments
Theres no point in having a go at me or mistahbungle,its "water off a ducks back" to us.
Youve been advised what to get(if you must)....in cheapest order.You can hit the search button and see threads about water damage which will give you an idea of solutions.
Ive read 100's of posts about water damage and some people have not had any problems.
So as things stand,your looking at spending between £8 to £150.

Problems with SGS3 - how to read logs?

Hello,
My friend has problems with her SGS3. It's about 1 year old and it started restarting and turning off itself. Sometimes it's on a keypress, sometimes while charging and something it just went off without touching anything. She sent it to repair and they said that there is some damage on motherboard from water (but it was never wet so it's weird) and it's glass is broken (it felt on the floor and broke a few days after buying), but the screen and touch digitizer work fine.
Since the repair is more expensive than new device, she wants to check if there is some software problems before giving it to someone who can try to fix it. The phone is not rooted, so is there any easy way to check its logs (some app or something)? Is it even possible without rooting?
In case of hardware problems, what should she do now? If the mainboard is broken and the glass is broken too, it's almost impossible to sell it for parts because only battery and soem minor parts are usable. Is it worth repairing the motherboard?

Isn't that the USB port? Looks like it's already fried. From the looks of it, the service center is right it's a hardware problem and for them to say that the motherboard is broken probably means other components are also fried. In my opinion it's better to buy a new phone as a repairing it outside warranty is much more costly than buying of a new phone.

Yes, it looks like USB port. Maybe something is fried, but the phone works so all chips and electronics must be okay. They said that there is corrosion on the motherboard. The phone was never wet but it can be due to condensation or humidity. I have a friend who told me that he can fix it if there is only little corrosion, but before trying, I would like to take a look on logs if there is some software problems. Another friend told me to wipe and flash original kernel and ROM from fresh, but I don't think that this is a smart move since the port could be broken and we could brick the device if it lose connection during flashing.

I see... so the phone still works. That type of damage is probabaly because of humidity like what you suspect. In my opinion further use of the phone with an existing hardware problem can lead to a more bigger problem so no logs can be of help here. That fried usb port can also hinder on flashing a new rom like what you said as it may fail during the flash that can corrupt the internal memory of the phone. I think your friend's options are only two. Have it repaired or just buy a new one.
Yes it works but it's barely usable. It's blocking (getting stuck) and restarting all the time. Do you know maybe how to read those logs? I never used logs so I don't know. I was googling about it but I didn't understand it well. It seems that the phone has to be rooted.

Help > I9100G enter bootloop suddenly n dead

the phone on like usual , put aside.. when want to use take it and saw it in boot screen.., wait quite long still stuck there.. take off battery and put back in straight cant turn on.. any idea to revive it?
download/cwm mode both not working... tried press 3 together and insert battery also no respond.. charge no respond too... is it mobo dead symtom?
EDIT: Charge it will hot but no respond
Same advice as this thread (I.E try the things I suggested to that person); though in your case it's 99.999999% likely you're going to need a motherboard replacement if you intend to keep the phone.

i cant find usb jig over here...
the person sttill able to go downlad or cwm.. this phone unable to turn on.. tried jump start by holding 3 button and insert battery do not work..
can i know how long should i hold the 3 button? as the post say too many people release early..
if the mobo really spoilt, will it affect the internal memory? for example i sell it to faulty phone shop, do they able to recover? if not maybe sell it and get a new phone
1) You hold the buttons as long as you have to - if it hasn't booted into download mode having held the buttons for twenty seconds, it won't be ever.
2) You can order a jig on eBay; you don't have to find one 'over here'.
3) Nobody can access your internal memory (including you). It's probably dead anyway.
If you decide to keep the phone, you get a motherboard replacement. If you sell it as is, expect to get very little money for it (the only part useful to someone else will probably be the screen).

it will turn hot when i plug charger on it.. so it considered death too?
planning to sell it out but only concern people have chance revive it back and get data inside..
Correct. Heat at the back + no boot = one or more components on the motherboard have died. It is impossible to read the data off an EMMC in these situations
As I said in my PP, if you sell it, the only thing which be useful for whomever buys it is the screen, assuming they don't replace the motherboard & get the phone working again, and as the EMMC is on the motherboard, new board = new EMMC.
Nobody is going to access your data if you sell it (and even if they could, why would they ? You're paranoid/read too much of the hysteria the tech media push as 'journalism'); it's gone (and I'm not saying this again, twice is my limit).

credit card data etc.. the phone is my bro 1.. i just asking... yesterday he told be that he bring to phone shop for last time before purchase.. the phone repair people say IC dead,, replace cost less than 100.. but dont know which IC, data depend on which IC...
You can replace the entire motherboard for around the same price. We've seen a number of posts over the past 12 mths or so with this 'replace power IC' fix suggested, but nobody has posted after saying the repair was carried out successfully.
It involves replacing an individual component on the motherboard, these components are tiny, and Samsung service centres/almost all other repairers won't even attempt such a repair. If this repair is unsuccessful, you will end up having to pay for a motherboard replacement + the cost of the failed repair.
So if the plan is to keep the phone, insist on motherboard replacement. You can source a 2nd hand one online yourself & pay a mobile repair shop to do the replacement (and many mobile repair shops may even be able to source one for you), and as I said in my first para, this will cost you not a lot more than what you've been quoted for this dubious repair, but you will pretty much guarantee to fix the phone first time unless there's other components not working.
By all means choose the option you've been given (replacing the individual component), but be aware there's a fair chance it may not work, and if this is the case you'll end up with extra expense if you end up needing the motherboard replaced.
If it was me, I'd want it fixed right the first time.
Anyways, this is my last post to this thread. Nothing personal, but I've given you the options, up to you/your brother to decide what you want to do, no amount of further to-ing/fro-ing in this thread is going to change that.
