QTEK 2020 POWER battery,the world record, I do it my self.can last more than a week in normal
it is 1200+2200*3=7800mah, SIX times MORE than the orginal battery, and the qtek2020 is wm5.0 frmo windows mobile 2003， I bought it three years ago
I found that this forum is for QTEK2020I, please help me to move the post to the "Himalaya & Andes" forum
Tell me do you walk around with that? if so do you walk leaning to one side? jeeeez must be like carrying a brick.
yes,I take it daily life. It's really much heavyer than the orginal battery,but being using for several days ,you will used to it,and you will fell how powerful when using gps(with buletooth),reding books,playing games it's. that's why I made it
Well I hate to tell you but I bought a 3600 Battery cost very little and I can go two / three days with out recharging if needed but soon as I connect to my car and the GPS its charged up and it doesn't weigh very much at all
yes,it's in city
but I make it for outdoor
LoL, amazing but for you security I think that you should not play with the batteries otherwise *BANG* likes LG one.
2 The Owl: Where did you buy 3600 battery an how much was it?
It was off of Ebay but I found their e-mail address it is [email protected]
and was £9.99 plus P & P which made it £15.98
Beware that the 3600mAh Battery comes from Hong Kong (which isn't a bad thing) but it does come with an extended back - and if you use them with a GPS, you will probably need to modify the holder to accommodate the extra depth of the battery.
But - the battery is really really good and worth having
I bought one of these mounts

I also as has been previously stated bought one of these Batterys
http://www.digitalera.co.uk/products/XDA_Battery_for_O2_XDA_II_XDA_IIi_High_Capacity-759-44.html
Both work together with out ANY modifications
Forgot to say I do use it for the GPS and this is the uint

lol amazing modif on battery
can you show the schema it's very interesting job
My Diamond is broken. Sent it to the local store and according to them the flex cable/board was broken.
Any recommended shop to purchase? I found several online shops but not sure.
By the way, the battery is drained faster now. One full charge only last 4 hours with no usage at all.
My question is does this weird battery issue has something to do with the broken flex board/cable?
Thanks.

to answer one of ur questions (altho i'm not sure if u want it answered?!?) eBay will probably be the best place to get a replacement, or if u can wait a week Deal Extreme may have one (will be cheap if they do + free worldwide postage)
Hello,
so today I bought a second-hand LG optimus black that was soft-bricked and had a cracked touchscreen. Since I'm not new to android and know how to fix these things, I thought this was just another way for me to get a good phone cheap.
The problem is:
- after unbricking the phone, and installing official v10a software, there are issues with the phone - camera force closes, any of sd cards wont be recognized ("removed sd card, insert a new one" notification, never changes), the screen rotation doesn't work, there is no lockscreen, phone dialer has lags, and the screen turns on after 5-10 seconds. Otherwise it's ok.
With software v20b it also likes to hang up. Theeen you have to remove the battery
So I dissasembled it, and it seems to have short circuited somewhere on the motherboard (there is a brown spot on the metal motherboard cover plate).
I marked the area in a picture below (notice that it's right next to the SanDisk chip - i guess that organizes the memory, so it should take care of the sd card as well). Keep notice this isn't the picture of my motherboard, I will post my own photos a bit later..
Maybe it was waterdamaged, but the sticker on the battery is white :/
Please don't tell me to factory reset, or try other software or memory cards, already did that.
CWM won't detect memory cards as well.
I need any possible ideas to fix it.. do you think a reflow would have any chances to do the job? any ideas, please, will try anything..
PLEASE, help.
Some update. So I flashed software V30B, and it seems to get better - finally I get a lockscreen, and not in 10 seconds also, the accelerometer sensor is working, phone is smoother. FRONT camera is working as well, while in video call mode, yay! when turning on the camera, it has a black screen with all the buttons and camera settings, and a message that there's no sd card (although it's inserted :| ) and hangs up if I switch to front camera. Memory card still not detected..
Thinking of capturing a video to show you whats the situation.. Till then here are some photos to show you my beauty
P.S. don't be shy, guys, any ideas for fixing?..
the photos
Anyone?
I thought I would get some replies, at least maybe I was wrong

Thanks for the reply!
Well I thought I would find more hardware technicians here, but whatever..
I downloaded the service guide for optimus black, and after looking at the schematic sheets, I'm 90% sure it's "SUB PMIC CAM POWER (LP8720)" controler that's failing. It controls the 5mp camera, microSD card and motor driver (vibration) power supplying. Neither of these functions are working on my OB. So no need for hardware hackers, nothing new they can tell me. So I'm thinking of ordering this pmu, but could you tell me guys where I could get it from with normal priced shipping? Shipping time wont matter at all.. Digi-key and mouser want to charge me with 40$ shipping, while all I need is a 2$ part

well mate, i have no idea..... i am just normal customer, if something wrong with my phone, and i cant fix it, i always go to official service center......
but, i hope you got some luck out there, happy shopping
Makes sense. Most people don't believe that ICs are a very sensitive component.
Obviously, I can't make a theory of what's wrong on that device, as I don't have it here.
Do you have a multimeter? On the service manual you might have somewhere what to do (e.g. where to measure voltages) if some functions are not working, or did you already try that? I know the service manual always ends with "replace pcb", as usually the technical support don't actually do the repairs, they just follow what's on the manual and send the old parts to the manufacter for repairing and reassembling, but it might help you understand if you really need to replace this IC. Is there any fuse nearby, for example? Remember, a short circuit would break fuses. You can check with a multimeter whether they're damaged or not (continuity test).
There's not much I can say, really...these are just some suppositions...
Good luck with that, man

I do have a multimeter, I'm kinda into electronics so..
Yeah, so I had a little break and checked the phone out only a few minutes ago.
The LP8720 is the problem, but its much more f..ked up than I thought..
I marked three spots on the circuit that are quite odd:
1. The place where IC U601 - LP8720 should be.
2. 2.2uH wire wound resistor L601 (MIPSZ2012D2R2 MIPSZ2012D2R2, 2.2 uH, N,2.0X1.2X1.0), not sure if it works, maybe it burnt out, my multimeter shows 0ohm on this one.
3. The place where capacitor C604 (10uF) should be.
I attached the pic of my motherboard, you'll see whats up..
The only place I can get LP8720 is alibaba.com, and the minimum quantity is 10.. that makes about 16 bucks for these. Would be worth buying and trying to fix? And another thing, it's named LP8720TLX-B, not LP8720TLX. Do you think it'll do?
I'm now thinking of taking it to a service center, ask if they could do such a job and how much would it cost..
Thanks for the replies, by the way!
Peace

Hey man,
keep an open mind
What makes you so sure that this IC is damaged?
Think: if the nearby components are damaged, then this IC may behave differently (or may not work at all). We don't need math to think this.
But yes, it can be damaged, but since this is the most expensive component, I think it is really worth checking the others first.
Anyway, answering your topics:
1. Everything looks fine. Good ^^
2. Yes, it's probably damaged. An inductor is supposed to have resistance, but not much. For this one, 0.23 ± 30% Ohm.
Source (datasheet): http://www.fdk.co.jp/cyber-e/pdf/CD-TCE070.pdf
3. Fortunately, this is an easy one. If in doubt, just replace it.
Now, for the headache...LP8720TLX-B and LP8720TLX might be the same IC, but the only way to know this is by comparing their datasheets.
16 bucks is a lot to pay for a component (yeah, it's 10 of them, but it's still a lot). But this is actually your call...are you willing to pay 16 usd for an IC? If it was me, and I was entirely sure it would fix everything, I would probably buy them, but then...like I said, your call.
I think it's worth taking it to a service center, but if they truly follow the service manual, they will tell you they need to replace the entire pcb. But I really think it's worth to try, you never know.
Good luck
Except for the fact that, given that the USB port deteriorated, so I could only charge my phone wirelessly, for months I've been using it very nicely, almost without problems for such an old phone, up to this week when this suddenly happened:
I went to sleep and left the phone with ~50% battery and didn't leave it charging, it was enough to wake up with it having some charge left, but upon waking up it didn't turn on and couldn't be charged, I sent it to a repair shop and I was told that they repaired the USB port, but that "something on the motherboard was short-circuiting and draining the battery", and that to find what and repair it could take until Monday or more.
I took these photos after it was disassembled and the USB port repaired.
What can you tell me from this information and the photos?
Can you at least tell me the repair shop didn't severely damage it?
I have more information, but I think it's only minor details, so not to bloat I won't post them now, but I can surely post more if needed.
Thanks!
I don't spot any visual damage.
How about buying a used phone that works? Isn't that cheaper than repairing your Nexus?
Hi! Thanks for the quick reply! I'm glad to hear there's no visual damage.
Let's see, first I already have a pretty decent fallback phone, it's better than Shamu in some aspects, though I still prefer Shamu in general.
Second, I paid ~$120 USD (shipping included) for this phone on ebay about a year ago (advertised as new, obvious it's not, but maybe it wasn't (too) used either? It has decent battery, and is overall pretty good except for the already mentioned USB port which quickly deteriorated, which I didn't mind too much).
For this repair I won't be charged if they break my phone or aren't able to repair it, even for the already fixed USB port (I think), for which they bill me ~$8.08 USD (exchange rate as of today), and for the suspected current problem, a maximum of ~$35.03 USD for a total of ~$43.11 USD.
That's still ~$76.89 USD away from a "new" Shamu, and even further (~$124.40 USD) from the other phone I want at the lowest price I can find (Honor Note 8 at $168.51 according to DHgate as suggested by kimovil).
Unless I can find a better phone, and better for me would be a phone with at least the same resolution but lower ppi, because I don't want pixels so small I can't tell the difference, but I do want a larger screen (so far I can tell between the 402ppi of my current phone vs Shamu's 490 ppi).
And if possible, I'd prefer a "new" phone, even if it isn't really new, but can be convincingly said it is.
So, so far, I still think the repair is pretty worth it. I know I'm kind of picky, but I think what I want makes sense, right? I hope that answers your question.
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:

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.

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.

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.

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.
