Hello guys,
I have an old Samsung GT-i9060 phone which I'd received from my previous employer. It has finally given up and is now completely dead. I suspect a faulty charging cable to be the culprit this time as my attempts at superficial repair has proven that the problem is deeper. I tried getting it fixed at a local repair shop but he gave up on the basis that parts aren't available and that the motherboard has gone kaput.
So, to summarize....
Samsung GT-i9060 completely dead
has been dropped several times and cracked digitizer has been replaced.
old battery is not at optimum condition but problem persists when tested with a new battery.
No vibration or samsung/charging logo on display when powered on battery or charging but certain areas of motherboard get heated up if I try to turn it on.
I got some important contacts and backup on this phone which I'd really like to salvage. I invested in a few basic tools and looked up a few tutorials on the interwebz but none seem to help me understand the actual problem. I am a novice when it comes to electronics and can easily try to recover the data through some specialists but the satisfaction in getting it done myself is priceless!
So any kind of help would be immensely appreciated.
Thanks
Make sure that the battery voltage is over 3.6 volt. Then connect phone to pc using usb cable without pressing any buttons then check pc detects phone's soc(broadcom interface) or not.
Thanks. Let me try that out and get back to you.
Update - @engage4 Battery was at 4.27V, fully charged. Connected to PC but it wasn't detected although I observed the same heating issue as mentioned in my original post (see attached pic)
Coincidentally, the memory chip and processor are on the exact underside of the mobo area that I have highlighted (which heats up)
For reference, my previous reply to you is here:

What do you mean by superficial repair? What made you suspect the charging cable?

Kaput? I know that word. That's a German word for broken. I wonder if he told you this because he wanted to repair the components on the board, or because he wanted to toss out the old board and install a new board and call it repaired.

So you already tested with a new battery. Good! That's one of the first things I would do as well. GSM Arena says the battery is "Li-Ion 2100 mAh, removable". At least you didn't need to send it in or leave it to a repair shop to replace the battery. I remember the time when you could replace the battery of your phone yourself. That in itself was very satisfactory. Those were great times! Those times are gone. Now you have to pay a premium to replace a battery. It's "complicated" they say, and so it's not for everyone (or anyone).

Hotter than what's usual for a phone that's charging? If it's shorted, charging may damage it further. You can test it of course, but you're risking it. Don't test charge for longer than you need to, preferably not at all as soon as you realize there's something wrong with the device. There's the risk of battery leaking or catching fire. So be careful and don't leave it unsupervised.

What kind of tutorials are you reading or watching? What do you think is the problem?
You have to go over more than a few tutorials if you want to be able to intuitively know what to look for or what to do. One way is to start learning about electronics in general, experiment and learn, before you get down to this specific problem. Another way is to start exploring from the repair side of things and work your way into the topic of electronics repair by troubleshooting this specific problem.
Your problem is most likely caused by a short somewhere on the board. So I would suggest you learn about short circuits or "shorts" for short (duh) and how to find shorts in general, and then work your way down to how to find shorts on mobile phones specifically.

I know that feeling. I'm wired the same way. If I can, I will try to repair and fix things on my own. Sometimes I will take on things I hardly know anything about. I will try anyway and learn in the process. Some things are admittedly more difficult than others. But that's how you learn and grow your knowledge base.
People no longer repair things. They throw out the old and broken things, and just keep on buying new things like on conveyor belt. This is not good in by any means. The biggest negative impact of this I think is that people stop using their head. They begin to believe that everything in the world is automatic. A light bulb is the result of true magic, especially when you throw in smart home plugs and switches into the equation. People are slowly being turned into slaves of consumerism. Common knowledge diminishes, like what household products you can use to remove stains, and we only live to serve a higher purpose of capitalism.
Do you have the service manual for this phone? You can usually find these online free of charge. Do you have a multimeter? The first tool you should buy and learn to use is a multimeter. Learn about the continuity test, diode mode, and how to measure voltage.
I worked as an electrician and I felt like I had to ask about how to measure voltage at a resistor, because I was unsure and didn't want to risk damaging a board more than it already is. As an electrician, I worked with voltages relative to Earth ground. I never worked with electronics, although I did get basic electronics training and I know all the basic components and how they work. We worked with soldering iron as well, and learned to use an oscilloscope. I was best in class at soldering. This was a long time ago though. We programmed PLCs, made Delta and Y-configuration connections of three phase electric motors, worked with relays and contactors, and we learned a whole load of other useful things.
My point is, always ask someone more knowledgeable and experienced if you're in doubt about something, rather than taking a risk or gambling. This is much more important of course when working with unforgiving high voltages and high currents, so as an electrician I learned early on to respect electricity. This was all part of my training and thankfully I have never had any accident. It's OK to make mistakes, and you're bound to make mistakes when experimenting, but you better have a backup plan and put in some kind of safety net, to protect yourself and to protect your equipment or whatever it is you're working on.

The USB connector on the charging cable I was temporarily using sometime back had a flimsy connector and I suspect the loose connection might have caused 'spikes' and maybe shorted some components/mobo.
I had dropped this phone on numerous occassions and almost everytime the ribbon connector for the LCD would come loose since the connector on the board was a bit wonky. I used to check this and get the phone working again. This is what I meant by superficial repair.

Hotter than usual, yes. I have tested and/or repeated the scenario only couple of times so as to not risk any further damage.

I have invested in a multimeter, soldering iron and supplies and a heat gun. I do also have a manual for the phone and it has helped me partially.

Thanks for clarifying.
Now that you mention it, one of my charging cable was a bit flimsy as well. Might be what happened with my phone as well. The connector would wiggle left and right so I would have to make sure it points straight into the port and rotate the phone left and right to make sure it's not tugging on it as I put it down on a book shelf. I always charge my phones on this book shelf as the power outlet is close by.
I have actually four identical Samsung 15 W chargers sitting there, all for the Galaxy S7. Three white ones and one black, and each with its own charging cable. I had purchased some extra chargers just as spares, and one of the chargers had a bit flimsy connection, as you say. I actually once spotted that one of the 4 pins on one of the charging cables was too short, and because of it, it was not charging fast enough. I stripped it down to bare wires, all for science and learning, before throwing it away.
On another occasion, I discovered that one of these cables didn't want to charge my phone when combined with one of the four chargers. It was a perfectly fine looking cable. The same cable worked well on the other three identical chargers though. So this was a bit of mystery I had never seen before. That will remain a mystery. That same charger also worked well when combines with other cables. So both the charger and the cable worked well, but only with others, not with each other. Note that these were all original Samsung chargers and cables. The "travel adapter", model EP-TA20EWE. They all came in original Samsung retail packaging. Although the spare chargers I purchased did have a bit stiffer and thicker cables, when compared to the original that came with the phone. They were presumably made in later years, so Samsung had probably changed them up a little bit.
But this goes to show that there is more to a cable and a charger than meets the eye. I suspect it had something to do with lack of compatibility across the many charging protocols that are in circulation in the fast charging universe, like Qualcomm Quick Charge 2.0 vs. 3.0 vs. USB Power Delivery 2.0 vs. what-have-you.
So you're not wrong to suspect something as "simple" as a charging cable. Not even a cable can be left alone, they have to make it "smart" and complicated. If the cable doesn't know how to talk the language of the charger, it's useless. Or worse, it can destroy a device. All because industry wants to satisfy inpatient people that want fast charging, and so instead of 1 standard, they make 4 different ones, if Apple Lighting-whatever is included. By the way, the faster you charger a battery, the faster it will lose its capacity and die out.

That depends where you look and how determined you are.
I ordered a new S535 power IC for my Galaxy S7 from Germany via Ebay, and I received it last week. I don't have the exact dates, but it arrived within the same week, so about three to five days. From Germany to Sweden. I also ordered three of the same chip from a supplier in UK, also via Ebay, and it has yet to arrive. This has to do with Royal Mail strikes, so everything is delayed. In addition, I had to pay customs fee and import tax from the UK. Not sure if it will be held at Customs service and delayed even more because of this, or if it will be delivered straight to my mail box since the UK supplier made sure I can pay upfront so it can be cleared for delivery. So I will have 4 of these in total.
Let me give you another example. I have an older car that's well looked after and only driven occasionally. A few years back, it started leaking oil from the rear axis. I went to the authorized repair shop. They told me they had to either replace the differential or rebuild it. But because it's an old timer, there are no parts for it readily available. This is a BMW car and BMW has a good reputation for stock keeping parts for old models for a long time. Well, maybe they don't keep a stock of big parts such as differentials. But it's not true that it's not available. I looked it up online and found several car stripping companies that have a number of these parts to pick and choose from, some of which were in almost new condition. So if they really wanted to, they could have ordered in from there. This is where small and independent auto repair shops order from as well. I even offered to order it myself and deliver to them. But they could not make the needed arrangements. Or rather, they didn't want to. I understood the message. They can't be bothered with something as heavy, oily, dirty, difficult, skill demanding, and time consuming as a differential replacement... and a rebuild is probably as distant as science fiction to them. I never went back there. I used to go to them for years and was always happy. Since they changed the owner and relocated, it's a completely different company. I would never again go to an "authorized" repair shop. They are properly titled "car dealers", because they are more interested in selling you a new car or a used car than repairing your old one.
It's the same with phone companies like Samsung and these places they call "Support Center" where you can walk in to get support and service on the device you already own, and they put up their latest "flagship" models on display and under your nose. That's how you know you're in the wrong place. It's all sell, sell, sell.

Make sure to get the needle-like test leads for it. This is needed for probing and measuring tiny components. The ones that came with my multimeter were very good, but they were not fit for the job, because they are not thin enough at the top. Most of the standard test leads have blunt tips. I ordered a pair from Amazon, a complete kit actually, but they are not very good. The whole kit was very cheap and I could not find any other, higher quality, more expensive ones. I don't want to promote Amazon, but I can post a link if you want.
A heat gun might work, but a hot air station is better. You need about 350 C to rework big components like BGA chips. Based on my limited knowledge, but extensive research. You should be able to tell what the temperature is at, and only the more expensive heat "guns" will have a temperature sensor and a digital display.
A service manual is a good resource. I wish I had a complete service manual for Galaxy S7. I looked for a places to buy one but I only found dodgy websites that seemed to be in the business of downloading free manuals, packaging, and selling. So if you have a complete manual, that's better. I only found excerpts of the most important chapters for Galaxy S7, and it has been very useful.
So, umm, there has been no progress on the repair front as I had been away on a trip and got my phone stolen
I was a bit occupied with reporting to the authorities and blocking my phone number hence I couldn't reply earlier.
Btw, I stumbled upon something called as boardview bitmap files; I'm yet to fully explore it but it seems really helpful.

Hi guys. I've been a member of this forum for a fair while now and you guys are the most helpful, wonderful and pleasant people to ask appropriate questions to, so I pray that a fellow statesman can help me with this problem.
I hooked up my TyTn II to my PC yesterday and noticed it wasn't working, trying everything software didn't help. I pulled the USB cord out and to my surprise, the furthest right pin was pointing a little bit wrong. So, I spent an hour carefully moving it back in place, connected it up, worked.
I have two methods of hooking up, one to my PC and another to a wall charger that came with my BluANT Bluetooth Car Kit. After reading that non-standard ports on anything other than an official HTC product can bend and damage pins because of the way they are designed or somesuch, I became a little paranoid.
But, everything was working fine.
Until this morning.
The furthest right pin was ON TOP of the pin to the left of it. I spent another hour moving it back in place, tried to plug it in to the computer, didn't want to go all the way in. I did not jam it. I did not push it. Looking at the pins I saw that the furthest right has completely ****ed itself. I can't see exactly if it's snapped or just bent right around, but it won't sync and it won't charge.
Fonebiz are apparently the HTC repair people in Australia, is it possible that the whole chargeport can just be replaced and I can have my phone back relatively soon?
Answers as soon as you can guys, I really can't go without a phone for long.
P.S. It's Friday and I'm getting an engaged signal everytime I call their Adelaide office.
Please help me.
EDIT: I am using a cooked ROM, running Touch Commander so it all looks legit on the surface, apart from the boot screen. I am hoping that this doesn't get the phone sent straight back to me, because it's a hardware issue. Am I correct?

I'm not familiar with what repairs that company undertakes and how quickly but certainly if you've been reviewing these forums for a while you'll know there are plenty of companies elsewhere that offer a broken USB port repair service. There really is something wrong with whatever you're plugging in to your TyTN II or how you're doing it. I've had mine since they first came out (bought it here in the UK at the end of September 07) and haven't had a single problem with the port despite regular usage of my charging cradle, non HTC official AC Adapter (the original HTC one blew up after a couple of weeks and 4 recharges), 3-in-1 USB adapter and 3 HTC Headsets. All pins are still straight as a die and connections rock solid. I'm careful not to get any dirt in it and always gently plug in the device straight on.

If you're wanting it repaired under warranty there are instructions in the wiki about restoring your device to it's 'as from the factory' state and you could use the micrSD method to restore all except your spl - that final step needs a working USB port (one of the risks in running a non-official setup while under warranty). I don't know what your chances are but I suspect a little better if only the spl is non-official than the whole lot (irrespective of what it looks like on the surface). Even if you have to pay for the port to be replaced though, as long as it's just a case of soldering in the new connector, that service doesn't cost the earth (at least from the American website I saw offering the service).
In all honesty Kiwi, I think the guy I bought the phone from didn't take care of it in the short time he had it.
But I got a TyTn II for $250 AUD. I'm happy to spend $80 odd to get it repaired in a neighbouring state.
Thank you for your words of wisdom, I am having it repaired as we speak.
I've had my tilt for a little over two years now and it seems the hardware has finally gave in. About two weeks back, the phone repeatedly got got stuck in a white screen when returning from sleep mode (as identified here: search "white screen issue"). I chose to dismantle the phone and replace the flex cable with one I had salvaged from my friend's dead tilt. Fortunately the white screen went away. In turn, I lost the use of the memory card slot, the touchscreen functionality only worked in landscape mode, and worst of all my sim card is no longer identified. Trying to revert back to my old tilt's flex cable gave me a empty screen all together. My question is, whether I should purchase both a new flex cable and screen or whether a flex cable alone will do? Moreover should I take a chance and dismantle an old tilt sold on eBay? Or just buy a new cable shipped all the way from China as there seems to be no US sellers? Any and all advice is welcome.
Sounds like you may have a loose/bad connection plug, need to recheck assembly.
The old ribbon probably failed completely due to extra stress during dissembly.
Parts from china are mostly copy parts & the quality is normally awful, buying a salvalge phone is a good option if price is right.
For sure a few forum members will have Kaiser spares.

Thanks for the response, but I disassembled time and again to check the connectors with the utmost care mind you . After some thought, I decided the salvage phone was not a a good option as those may have severe wear on the cable as well and I'm not willing to wait around for a week for the item to arrive to find its dysfunctional (or nearing its fate). Fortunately, I found a legitimate eBay seller in NY who has the new flex cable. Hopefully if the phone recovers, I will update for those who might come upon this thread and have found themselves in a similar situation.
whenever i try to charge my note or connect it to pc it keeps lagging badly i mean i have to keep moving the cable backward for it to work and its very senstive with just the slightest move it will stop charging again ! what do i do ? do i have to change it ? i really don't drop my note or anything i try to take care of it as much as possible and changing it might be a problem for me since y parents wont agree ! any help ?
Well i do think that you'll have to change it. the charging port seems to be very problematic for the note. And almost all the note users here with the same problem have replaced the port. i guess it'll be done for free if the phone is in warranty. I'd like the other users to tell me the approx cost of the replacement.

many thanks to you ^^ yah me too its true that i am under warranty but just in case they refused to do it how much will it cost ?
I have this problem and I fixed it by using a real samsung original usb cable. this problem is evident when i use cheap after market usb cables. the cheap cables seem to loosen up and their contact pins inside wear out. this is when you will have that charging problem.
If you have any mechanical abilities, it takes about 15 minutes to replace. Many youtube videos on how to do it.
Port isn't expensive, maybe 10 dollars (us), plus shipping. Just insure you get the correct one for your model of
phone.
One thing I would take care of is to take care of who you buy it from if you do so on ebay. I replaced mine and it's incompatible in some way, speaker now doesn't work and signal is terrible.
Make sure you search their sold items for feedback saying it works fine. I was reading through a thread for SGS2 USB strip replacements and mingxing2008008 was a recommended seller for that one, maybe they're reliable in general
Yay! Sony has repaired it.
A few weeks ago, my retailer sent back my device. Their report said that the front adhesive was loose hence there was water damage.
Thankfully, it was covered under NZ warranty and they completely replaced my z3. Yay! The rest is history.
Thank you to everyone who helped. I appreciate it.
Old post.
TL;DR: Phone won't boot or respond. When the phone is plugged in, the device's notification light flashes red. Tried all the button combinations, no response.
This happened yesterday. Searched the device forums and couldn't find any solutions so posted here.
When the phone is plugged into a power source, it the notification LED flashes just over once a second.
Tried using different USB cables, chargers, computers - no difference.
Tried all the button combinations, nothing happened. I did press the yellow "off" button by the Sim card slot and then it vibrated 3 times. Nothing happened afterwards and I couldn't repeat this.
One weird thing I did notice is when the USB cable is half plugged into the charger/laptop the phone, the led stays on longer. Maybe 5, 10 seconds. The time the LED is off is still the same. So maybe it's somesort of lose connection?
It doesn't charge via USB. I haven't tried the magnetic dock connection since I don't have one. Anyone know if it would be worth to DIY one to make sure?
Yes, the phone has been fully submerged in water, but I only did that when I got it last month. It hasn't been intentionally submerged since then. The only software related issue I had was that occasionally the phone's screen wouldn't turn on for a long time. I assumed this was software related and it was fixed when I uninstalled Microsoft's Next Launcher.
I've had this phone for over a month and it. Just returned from the city which I bought the phone and I don't want to return it for warranty unless I absolutely have to. The bootloader is locked and the device has not been rooted.
NZ has a great "warranty" law (Consumers Guarantees Act) which pretty much means if the device doesn't last as long as it's meant to or doesn't work as advertised, you have the right to a refund, replacement or repair at not cost to the user - so at least I have the law on my side.
Any response will be greatly appreciated - that "thanks" button will most definitely be clicked.

That - that would make me return the phone right away. If it's hardware related I wouldn't take any chances. Maybe you can even get them to give you a cover/case for the trouble

Yeah, but then it takes like a month for it to get mailed to the "official repairs", looked at etc. like most warranty claims. I'd rather get it fixed now rather than wait.
But as a plan B, I think we have it pretty good here!
Buy one of those super cheap magnetic chargers and see if it charges/turns on.
But Id also rather advise you to claim warranty.
This is no normal behavior and if you really test the USB Port as defective with magnetic charging being fine you would still want to claim warranty since the USB connection is crucial for a lot of useful things.

Unfortunately, Amazon doesn't ship many electronic items here so I can't get the magnetic charging device.
I think after exhausting every option available to me, now is a good time to claim warranty.

Take a known good USB cable and wall charger (must be wall - not computer) and plug it in and walk away for at least 2 hours. Don't touch, breath, look, or sniff at it. Then go back and see if you can power it on. If that fails you can try to restore it with the Sony tool or the flash tool but its likely done.

Of course, I dropped it in water! Several times, on purpose with no adverse effects. It's IP6X certified .
But that was when I first got the phone. It hasn't been intentionally submerged since then. All the ports were always sealed tight and all. I'm still really confused about what's happening to my device.

Friends tive that same device problem is only with the red LED on.
The solution was to use the flastools , installing a new ROM ..

Sorry for my bad english !!
Hi guys. I recently used a questionable charger with my phone (leeco le 2 x526) and since then it has been problem after problem with the USB port. Immediately after that charge, the phone stopped charging with the supplied quick charging brick. It won't even charge slowly. The phone behaves like the charger is being plugged in and out about five times and then completely stops as if the charger is no longer detected. However ,when I put it in a normal slow Samsung charger, it charges to the end without disconnecting.
It's not only the charging that's not working. A Windows PC I have connected the phone to before doesn't recognize it so mtp doesn't work. The PC says the device has malfunctioned and windows does not recognize it. Lately the phone has started rebooting randomly so it seems like I need to fix it soon.
Also, when I plug in headphones using the 3.5mm dongle, I hear crackling sounds for the first few seconds and Jack detection doesn't work sometimes until I reboot. Sounds play okay when it's detected. The microphone and media control buttons on headset have stopped working and I hear static when I press the buttons on my headset, sometimes it's quiet.
I'm pretty sure the USB board is the one that's damaged but want to know if anyone else has faced this issue. If it's the USB+mic board that's damaged I'll order one on AliExpress. I found it for like 8 bucks.
I'm thinking I have a hardware failure because since it started acting up, I tried to flash a ROM clean and got an error in TWRP. The flashing finished but I saw a red error message:
Code:
rcv error in uevent
I googled and this error occurs when the kernel fails to initialize a hardware component.
Has anyone experienced the same problem? I don't want to replace the board without a second opinion.
I believe that you are definitely on the right track with the replacing board, this same exact issue happened to me once on my first Leeco X727. In my case I was lucky enough that Amazon agreed to exchange it for a new phone. Without a doubt, many Le Pro 3 owners have seen this exact issue. Your questionable charger possibly shorted out the USB card.
I would strongly suggest that you replace the battery, while you are at it, it will also be very cheap.
You will need to use a Heat gun to remove the display without damaging the LCD, there are many videos on youtube that demonstrate the quick sweeping technique and the glue will easily release enough that the screen will come off simply by turning the phone onto its face side.
While you can also use a hairdryer, you will need to run a guitar pick along the edge of the screen to remove the display and it's very easy to damage the LCD...I did! Consequently, I bought a heat gun at harbor freight for $ 7 dollars, to easily the display on a friends X720.
Good Luck.
PS : Did you receive your Le Pro 3 yet?

Thank you so much for this advice. I will replace this board and see if it solves the problem. About the heat gun, I don't know if I will use it much after this repair so I'll take the phone to my friend who has a repair shop to change it for me.
One quick question... Is there a high possibility of damaging the battery during this repair? I don't want to replace it if I don't have to because mine is still pretty good and keeps like a new one. I don't have much luck with AliExpress because the original batteries for Le 2 cost almost $150 to ship. The rebranded batteries cost less to ship (~$10) but I don't know which one is reliable.
My Le pro 3 is still in transit. I reckon it's still about 2 weeks away because shipping takes very long to my country. I'm just now going through the various development threads to find a good ROM for it. Thanks again -- you're a godsend ???.

No problem.
The battery is underneath the heat shield so it will not be affected by the heat gun.
Attached are pictures of my LeEco Pro 3 with and without the main heat shield...On the far left

Edit: Opps, that link didn't work to well, here is the actual post link with better quality photos.

I flashed a ROM from 4pda and totally messed the phone up. That ROM failed to boot and to make matters worse, it formatted my data partition. Everything is gone including my backups and I cannot transfer a new OS to the phone because my USB port doesn't work. The only thing I can do now is to shelve this phone until the replacement USB board arrives. You have been of great help and I appreciate it extremely. I'm using a feature phone now until my pro 3 comes. To use any Android app I have to share my wife's phone which just sucks. (She barely puts the damn thing down)

No doubt we never realize how much we rely on these devices until they are gone.
You will definitely love the Le Pro 3, it is much more powerful, and the camera is phenomenal.

Absolutely true. I have a new found appreciation for my phone. Now that I think about it, with the time I spend on it I think some digital detox is in order.
I received the USB board from AliExpress but it is incompatible with x526. Anybody with information on where I can get a board for x526 please share it here. All USB boards on AliExpress are for x620 and they can't work on x526.
I am actually thinking about looking for the x526 board in India because that's where the phone was built for. I just haven't figured out how to go about it. But I reckon there is a lot more need for spare parts there because of the high number of people using the phone.

My le 2 is finally back to full working condition thanks to you. This USB board doesn't look used at all. The best part is that mtp and fast charging are working again.
