HI guys,
i have 2 problems from 3 days:
i have a problem with my SG2 when i disconnect the charge cable my phone continually stay in charge and every 10-15 second say me charging paused voltage too high.
second problem is USB , when i connect my phone to my computer it does not recognize it .
3 days ago all work perfectly now i try to restore stock firmare, full wipe but the problem persists anyone can help me? thanks
Sounds like the USB circuitry issue we see a fair bit of on here. Given you've already done a wipe & gone back to stock & you're still seeing the problem, I'd say it's a repair job.
Edit to add - You could try gently cleaning the USB port with an new/unused toothbrush before you do send it in for servicing.
maybe is hardware problem i dont know But the problem is in the same spot may be the cable entry which is damaged
Yep it could be the socket itself is damaged rather than the board. I guess they only way you'll know (assuming cleaning it doesn't work; which it probably won't) is if you have a mobile tech take a look at it.
The cable itself can become worn on the pins from multiple flashing and removal of usb cable .

Guys, I'm convinced the usb connector on my 9 month old TP is defective and gets worse each time I use it. I had bought a touchstone charger to ease the connector wear but still, I was eventually having problems with USB data connectivity using store bought cables. I even sent my TP in to fix the connector and when I got it back, still no USB connectivity. Just a completely wiped TP. So HP sent me one of their "genuine" silver dot cables and low and behold it worked fine. (My original cable was lost)
Now, months later, I'm having problems with the USB data connection again. I either get the "Not enough current message" in WebOS or no MTP USB symbol in CM9. Sometimes the PC will chime positively but with an error message (can't detect device). I received another genuine HP cable and it behaves the same as the other one. Inserting them normally, they appear to be in tight, the PC will chime but Windows will say that there's a problem, can't detect device. The only way to get it to work is to insert the microusb side at a 45 degree angle tilted downward and hold it in for 5 seconds, then (ever so slowly) release the pressure to the connector. 50% of the time I'll get a Windows message that says the USB is degraded and run slower than normal (which I think means it thinks its in USB1.1 slow xfer mode) and 50% it works fine at USB 2.0 (until I pull the cable out of the connector). I also have 2 store bought cables that won't ever successfully connect to USB with the TP but work fine with my Samsung cell in both charging and xferring music over to the phone.
So what I'm getting at here is that no standard microusb cable is the same and that there must be something special about the HP genuine one. Do these cables have a resistor on pin 4 ID tied to GND pin 5? Even so, I think what is wearing the most is pins 1 & 2 and maybe 3 (VCC and the data pins) which is why it may only work by concentrating on seating those pins first. Does it make sense that the 'can't detect device' message comes up with just the data lines and ground connected but no VCC? For that matter, why would the battery symbol in CM9 always show the lightning bolt assuming pin 1 VCC is not connected?
I'd appreciate any responses from other members here since I believe without USB the TP could be bricked in case some boot code gets corrupt and you are forced into WebOS recovery mode. This has never happened to me yet and I've installed a lot of nightlies but it COULD happen, no guarantees. What is inevitable is my connector will eventually wear out and my TP will only live until the bootloader DOES get corrupt, hopefully later than sooner. This could be the case with all TP's. Just imagine if in a couple of years everyone's TP's USB port goes bad. Sounds like the devs should figure out a way to fix a bricked TP wirelessly, if that's at all possible.
Thanks,

One of my Touchpad's had the same problem in Webos it said using wrong charger may not charge or something similar and with Android ie nightly the charging signal came up but it did not charge.
I spoke to HP and pointed out that I have 2 Tablets and that swapping leads or chargers made no difference all combinations worked on one but not the other.
They agreed to fix it and replaced the part. It is now working fine. And as with yours my computer failed to recognize the tablet properly.19 times out of 20 on the one time it did I was able to back up and remove Android before HP picked it up.
I would send it back under warranty or if that has expired state that it was preexisting. Otherwise as you said it is going to become pretty much unusable.
Don't let them fob you off.
Good luck

if u bought it during the fire sale u have about a week till (8/20) the one year warranty expires.

go to palm support and CHAT with them. do not call cuz that cost money.
once u get an RMA they will send a box and take care of Shipping.
then go here to wipe and remove android

Thanx for your prompt responses. I bought my TP at the 2nd fire sale through BB in early Nov so I still got a few more months but I would rather wait a bit more since they did nothing the 1st time around. I think the connector is on some daughter board along with the vibrate device which is soldered to the main board. Doesn't sound like a big deal to repair it. Still, what makes the HP cable different then the others? Are there known cables I can get online that might be made better to always work and make better contact than the HP ones?

Thanks for your advice. Did they fix everything that was intended? Was turn around time no longer than 2 weeks for each repair? When was your last repair (busted speaker) done? Is your serial number the same or did you ever get a replacement (meaning a refurbished one) back?
Thanks

i keep track of the serials and they always came back the same. i have more than one pad and i asked for one to be replaced completely. we will see if that happens. but they fix only what u ask for and nothing else.
it can take longer depending on Weekends. takes 2 days to get your box, then 2 days to get it to HP, then 3- 4 days to get your fixed unit. its all done thru UPS, cant send it out on the weekends or receive it

Thanks, you are giving me hope to try again while my warranty is still good. Maybe I'll put a big note on the screen PLEASE REPLACE USB CONNECTOR - wouldn't hurt.

Hi all. I know this thread is really old, but I'm finding myself dealing with similar issues. And I'm obviously out of warranty. I can't get windows, linux, or Toolbox to pick up the USB. I'm actually in a worse case scenario mention here and am stuck in meboot, TWRP, and WebOS recovery, because I had wiped the rom. It must be an issue with the USB port, I've lost track of my original Hp touchpad OEM cable, and have tried every USB cable I can find. Any help would be appreciated.
A month or two ago I started experiencing problems while connecting my S2 to the PC or laptop using the data cable.
When I connect the cable to my S2 on the PC or laptop it comes up with the balloon messages in the system tray:
USB device not recognised.
Then a short while later it comes up with another balloon message:
This device can perform faster.
Sometimes while transferring data, it will disconnect and the file transfer fails.
Sometimes if the cable is moved slightly it will cause the device to disconnect from the PC.
And, of course, the file transfers are much slower than they should be and much slower than they used to be.

I9100XXKKI3

I haven't touched any ROM or flashed anything on this in like over 8 months so it's nothing to do on that front.
I removed micro SD card and tried reconnecting again, still the same problem.
I've tried different computers, still the same problem.
I've used different cables, still the same problems. Tried enabling and disabling USB debugging. Same problem still remains.
The USB cables and computer and laptop work fine with my S3.
All the correct drivers are installed for the S2.
I'm resigned to thinking it's a hardware issue as I've exhausted other options. Is there a simple fix or will this need sending back to Samsung?
I've had the phone over a year now but someone told me the warranty is two years?
All help appreciated guys. Thanks in advance.
Why don't you upgrade to ICS?

Probably because his USB port doesn't currently work properly.
@OP, this is often caused by a dirty or faulty USB port. You can try cleaning it, but you may need to replace it.
Try cleaning it out with a dry toothbrush first.
If that doesn't work, take the battery out, and try cleaning the port with a small q-tip with a small amount of isopropyl alcohol; let it dry for a while after that, then replace the battery.
If THAT doesn't work, you'll probably need to replace the part for the USB port.
If your warranty is still good, you could try to go that route, but you'll need to unroot your phone. Otherwise, I've heard it runs about $15 for the part, and you can replace it yourself. If you don't feel up to it, you can have a cell repair shop or Samsung service center do it for you, but it will probably be significantly more expensive than $15.
My opinion based on your description is the USB socket on the phone is wearing out/damaged. The USB socket is on a small circuit board separate from the main logic board. It's easy to replace and the part is cheap on EBay. Search for a disassembly/tear down video and judge whether you can do it yourself.

Thanks for the very quick responses guy. They were very thorough as well.
I will look into cleaning the port and if it still doesn't work I'll consider having it repaired. My soldering skills were excellent but I haven't done it for a few years, so may leave it in someone else's hands.
I haven't upgraded to ICS as I was very happy with my phone at the time. Also, a couple of friends who had upgraded to ICS on their S2 regretted it due to numerous problems, which put me off upgrading.
You can still use mobile odin and theres no soldering needed with the usb,it comes as a board with a ribbon cable.

I've had a look on the Samsung website here:
w ww.samsung.com/uk/support/warranty/warrantyInformation.do?page=POLICY.WARRANTY
It seems as though the warranty period on my phone is 24 months so I might just get it done via Samsung.
I'll contact them in the morning and see where I stand. If not, then the replacement USB board connected by a simple ribbon cable sounds like a doddle. I've seen a grade A condition part on ebay for about £8 delivered.
Thank you once again.

This is a Cable problem. The USB port of your device is wider now, that's why the cable doesn't fit well. Buy a micorUsb cable for blackberry, it's always very full and thick, then use it to connect your phone. The issue should be resolved.
I once had the same problem with my Nokia N8 and using a Samsung cable (which looks fuller and thicker) solved it.
Yeah warranty should be 2 years BUT youll have to unroot it first if your sending it to them.
They may also wipe your phone and stick on 4.0.4.
If you get the board yourself,check the number is going to be the same i.e the spare one I have here is GT-I9100 rev2.2.
Also other people have got a replacement board and the mic doesnt work(think the boards are sold as refurbished).
So its up to you which option you go for.

Hi all,
Long story short, I went on a brief (1 week long) trip and just went back, and during the trip I had my HDX7 stored in a locker in powered off state. The weather during the week was rainy, but the storage locker was quite deep inside the room.
Before I go on the trip it works alright; however, when I'm back, I surprisingly found that it no longer connects to the PC, i.e. no USB debugging or MTP notification at all when I plug the tablet in.
Here's where I'm at:
No ADB and MTP recognition, either in OS or in TWRP recovery
Tablet charges normally at full speed
Different cables on hand doesn't help
Different ports on the PC, even a different PC, doesn't help
At this point I'm ready to accept that some sort of hardware damage has occurred, however, I'm still willing to know...
Is this really hardware damage, or have I missed something?
If yes, how come?
Possibility of repairing?
Thanks for your insights.

Charging takes place on the two outer pins; data communication on the two inner pins. Look for a bent/missing inner pin. More likely one or more solder connections have broken where the USB recepticle attaches to the main board. Not a fun fix; just say 'no' if inexperienced with such mods.

While I have tools for disassembly and some experience, HDX7 is definitely beyond my ability to dismantle just to check what's wrong, let alone repairing it on my own.
Guess I'll just sell this thing cheaply to someone who can bear with transferring files wirelessly...
I'm wondering if anyone has suffered with and recovered from the sudden case of no charging/USB>PC recognition?
I've seen countless similar stories across the web, covering many of the Z Family. Some were simple reset jobbies, and I've seen as in-depth as what I'm assuming is an IC being removed, flux cleaned and re-applied (w ww .you tube. com/watch?v=ZyCeNfc99a0).
I purchased a new charger port and also a new battery, as I figured with all the insane constant burning of my pocket, it could use a new one. I'd hoped it was just a charger port issue, but much to my dismay, the issue still persists after fitting them.
I've tried every single button combination "fix", and all to no avail. Multiple leads, charger units, all that polava. Checked and cleaned connections with isopropyl alcohol, checked for burned-out looking mainboard components, at least those that are visible.
I was having minor inconsistent charging issues for a while, up until last Friday. I figured it was the USB port on the phone or the leads, and put it down to general wear and tear.
Last Friday I was at my mates house with super low battery, popped it on charge round his and I noticed it had died completely and kept boot cycling, like the charger was being plugged in and taken out over and over.
I took it out and tried it when I got home with the regular charger, and nothing. My phone is otherwise in mint condition and has been looked after since day one release in the UK.
I'm wondering if some super helpful person here would possibly have some other alternatives that haven't been mentioned, whether a hardware bypass or some trick that isn't amidst the countless cries for help out there.
Many thanks in advance.
Hello,
I have a problem when connecting to a charger it will go in strange charging mode that actually does not charge. It makes the sound like a charger is connected, no charging animation on battery though...
The problem for me it was the USB cable used for charging (i have changed 5 of them in 1 and a half years). Also same behavior happens when using a under 1A wall charger.
P.S. : The USB cables that i have changed they still work fine with other devices/phones .... but not with my Z5C. I`m not sure what but is definetly something wrong withe phone usb port (and it is not dirt).
no, but
I cannot get a usable USB connection to my computer, but if I hold Volume Up while connecting the USB cable to the computer, the charger LED turns red for a moment, then blue. It WILL charge in this mode, which I think is fastboot mode. Someone said it bypasses the charge circuitry or software, which makes me think that maybe I could go into developer mode and turn on OEM unlocking to see if I can stop it from trying to optimize charging. I also have not tried all the USB connection modes yet.
I tried to charge with this blue light technique on the wall charger, but that did not work. Just ran the battery down again and I could not boot the phone.
I know if I press Volume Down while connecting the USB cable to my computer that the charger LED turns green, but I am not sure it will charge in that mode. I think this is for flashing or something, but since my computer does not recognize the USB device no matter what I do, I don't think flashing is an option.
Oh, and when I do charge the phone with the blue light special (old obscure USA discount retailer reference), for some reason the charger LED flashes white every 4 to 5 seconds, but it seems to keep enough charge to get me through at least the day until I can charge again by same method.
Maybe we can keep pooling info here. I got the blue light technique from someone else on this site, so there are people here who know quite a bit about this phone, thankfully.
Well, I had that issue, too (at least it sounds pretty familiar).

Does your phone also believe to be connected to "something" all the time?
I fear there is some IC fried, although I never dared to open my phone.
My "solution" was to talk my local salesman into giving me a (used, but working) replacement phone, and I did not want him to find any traces of DIY
So, no, I never found a technical solution, probably they just scrapped my phone for spare parts, idk.
The root cause for my error (probably) was a faulty charger, therefore I am pretty sure I fried something hardware-like, but depending on your cause, ymmv.
Anyway, trying to clean your USB port, re-soldering the connector and/or replacing the battery sounds like being worth a try, anyway.
// edit: "cat /sys/class/power_supply/usb/present" used to always output 1, even when not connected. On my now-good Z5C this works like it should (connected ->1, not connected -> 0)
Hey people. I have tried all the tricks for several days. Tried several charging cables. Nothing worked for me. I just brought a new phone, and it came with a cheapo charging cable. Decided to plug it into my Xperia and it worked. Maybe a little fairy fixed my phone when I was out buying a new one. Anyway, I'm love my Xperia Z5. Using it right now. Good luck people
