Hey guys, thanks for dropping by.
I have a very wierd problem, that I just cant figure out.
It all started the other day, when I found my tablet dead after having been left on and charging during the night. The tab was dead, and I feared the worst. After having left it on what seems to me like a trickle charge for several hours, I managed to get it up and running, and the tab seems fine, it was just completely out of juice.
But my troubles are not over. Whenever I'd connect the tab to the wall charger, I'd only get the red "X" symbol in the corner, and it would say MTP Initialize, even though its plugged into the standard OEM wall charger that comes with.
When I connect the tablet to my computer using the same cable, nothing happens, and by that I mean nothing. Computer doesn't start the connection process at all, its not recognized in the device manager, nothing. Not even Odin can see the tablet when I put it in download mode, the tab keeps saying "Waitting USB Cable..."
Tried this on 2 computers, still no luck, even using a USB plug on the motherboard instead of front-usb.
Now, the tablet will "trickle charge" from both the wall charger, and the computer, but nothing else happens.
I figured it could've been the ROM, so I got the latest ICS Kanang ROM downloaded, transferred it to my tab using Bluetooth, and flashed this without hassle, but the problem still persists, only now showing a regular charge icon in the lower right section, but it is still only trickle charging as far as I can tell.
All I can figure is a defective USB cable, or even worse, defective port on the tablet itself, but I'm not sure. I've ordered a new cable from DealExtreme, that will hopefully arrive sooner rather than later.
But seeing as the tab is hardly 4-5 weeks old, I find it difficult to believe the cable is the problem.
Anyone have any ideas? I'm all out at this point, so any pointers is very appreciated. Thanks.
It could be the cable. It's the part you have used in each situation. I'd wait for the cable to arrive and test it with the tablet when you get it.
Sent from my GT-P7510 using xda premium
Hey, thanks for the reply.
Yeah, I really really hope this is the case, time will tell, DealExtreme is not the quickest dealer. I'll update when I get it.
The new cable came from DX, but I'm afraid it showed no difference on anything.
The cable is working just as the original one, so that's not the problem.
Anyone have any ideas?
I guess my main goal at the moment is flashing it back to stock and un-rooting so I can get it repaired.
You mind posting a screenshot, it's kinda hard to imagine what you see by what you read For all I know my imagination went from a red X to the corner to something like an X off battousai's face.
Then again, I'd be glad to help, provided you post screenies, would be a major help
Ah, yes, I will take screenshots of anything you want to see.
Right now im on ICS preview, and these are some snapshots WITH the cable connected.
The red "X" I'm talking about you can see on the first picture on the charging icon, this happened even when the wall charger was connected on gingerbread/overcome experience rom.
The other pictures you can see it says discharging. Now, this was taken when connected to the computer, and I guess that's normal, but it also happens exactly the same when connected to the wall charger that came with the unit.
If you want screenshots of anything else, ill get it asap!
I took a poorly image of the tab connected via USB, to my computer with Odin open, hopefully you can see what it says.
If not its just what happens, I don't get further.
By the screenshots, Is the language Swedish?
Then again thanks for providing the screenies
In your first screenshot that could be part of the theme, or was it never there previously? I don't really know if it's not charging or that's supposed to be the charging icon, because for some odd reason on ICS preview I don't see that red icon anywhere.
As for the tablet, the reason why you aren't detecting it seems as though you don't have the drivers on the PC, I don't know if you installed them or you didn't mention it because I never found it being mentioned in your reply. I know it sounds silly but the same thing happened to me when I was using the tablet, (originally my 3G series belonged to my dad who knew nothing about modding so he just gave it to me and said, "do your thing" ) He did also forget to mention that you require to have the drivers to detect it via Device Manager and MTP in general, shortly the COM port will show up aswell. Perhaps re-installing the drivers should do the trick?
Made me wonder how did you install ICS in the first place if you weren't able to have it read? But I realized you could have downloaded the zip file via the tablet, On another note, how did you install CWM in the first place? o.o
Hehe, almost! Its in Norwegian on the honeycomb picture.
The red "X" would show up whenever i was connected to the PC via USB, to indicate its not charging. It will however "trickle" charge, and take 24h to charge fully with no usage and turned off.
Yes, the red icon is not on ICS, it just says not charging in the about page, as you can see from the screenshot.
Drivers have been reinstalled two or three times on two different PC's, I don't believe this is the issue.
When I bought the unit, it was working 100%
USB was okay, I flashed and rooted the unit over to "Overcome Experience".
From there I transferred ICS preview via Bluetooth and installed that way.
Have you tried factory reset to make sure all modules are reset? Maybe the USB charge module in Overcome is conflicting.
Yes.
Factory reset 3-4 times on the two different roms. I've reset everything I could find, without success.
Perhaps it has gone faulty with the tablet's plug in port, someone had the same issue although it was his wire that was at fault, it detects the charge via USB but not enough volt's to be detected by the PC, has it been grounded? Seem's more likely :| Might have to get it checked in your local center perhaps, It's how I mentioned that any metallic object is able to relay electricity despite being broken or not, you may have a broken pin for all I know :|
Hi,
I'm having exactly the same issue with my 1 month old tab 7+. I tested it using my bosses charge cable and there is no issue so I need to go to the service centre for a warranty replacement on the cable.
Hope you sort out your issue soon!
Thanks, but I don't think I have any other choice to deliver it to Samsung Europe as a payable service to get it fixed.
Purchased on a American store, and I doubt they'll take it back with flashed software.
I'm not sure really, I'll see what I end up doing. Its not the cable, that's for sure.

Greetings!
So, recently, my Transformer Prime stopped being able to connect to my PC. When plugged in, the Prime does show that it is receiving current on the cable, as the charging symbol shows up, but that is all. Windows shows no indication that the Prime is plugged in. This includes looking in Disk Management and in Device Manager. Nothing. Oh, and USB debugging on the Prime is turned on.
I have tried two different cables (both of which will definitely charge the unit), and 3 different PCs, all with no change. Additionally, there is no visible damage at all to the port.
I even ROM'ed it (after the problem started) with Cyanogen10 and nothing changed. Finally, I tried it with the dock, and while the dock works fine when they are coupled, if I plug the dock into a PC, still nothing.
I am sort of out of ideas. Anyone else have any?
Thanks!

There is another thread with a discussion on this. Perhaps it will help. Read through the posts to see any trouble shooting suggested, but I'm guessing your USB port is dead and will need to send the tablet back RMA to get it fixed - sorry to say.
See the thread here: http://forum.xda-developers.com/showthread.php?t=1624175
I had the same issue, and unfortunately soft bricked my prime while trying to see if different ROM's would fix the issue. the soft brick would have been recoverable if my prime would connect to my PC, but it didn't so I ended up paying Asus to repair the unit.
If none of the troubleshooting works, I'd flash back to a stock ROM and then send it in. mine would only boot into CWM so once they saw that, they figured that was the problem and charged me for the repair. I had seen a couple of people say that even though they were unlocked, the prime was fixed for free since they were able to boot up into the rom.

Can I ask how much they charged you to fix it? I'm about to send mine in for RMA, but have a cracked screen from a drop. USB worked for weeks after the screen crack, but I'm concerned they will say it broke due to my neglect. (Basically I don't want to spend too much to fix it with a broken screen). If I can get the USB working again, I'll consider spending some cash to fix the screen - but to pay for both I'd be better to just but a new tablet.
Never mind, I see you already answered me on a different post. $232.
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.
http://kb.hpwebos.com/wps/portal/kb/na/touchpad/touchpad/wifi/supportservices/page_en.html
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

once wiped send it in and your speaker will be fixed, it will take about a week.

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

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.
On my TF201, about an hour ago, my USB connection to it just dropped. No loose connections, brand-new cable. I had thought it was just a bug in my USB drivers, so I quickly unplugged/replugged the device. No connection. I rebooted both devices at least 2 times, and still no luck. I figured that I might be able to determine what's wrong by connecting the cord to the wall plug. It charged just fine. after that, I assumed that it was the computer's USB port, so I plugged my phone into the same port. Was able to get adb connected to my phone, no issues. My question is, How could I determine what the issue is, without RMA'ing it or resetting it?
(Also wondering if me connecting a flash drive to the keyboard dock with it showing up for a split second then going away is any indication of anything, I'm just going to assume the worst and say the USB is shot)
I have the same problem bro. I don't know what to do I am be very pissed. I read somewhere on xda a guy had a problem with his epic and took a qtip with alcohol and cleaned the contacts and it worked. I will try this tomorrow and get back to you. I have tried other pc but nothing works and I hate not having root and I add-on considering selling my prime just because of this
Kinda have it working, in the sense that the USB cable, when connected, will make the device show up in Device Manager as an "Unknown Device", but much past that, I'm not sure. I don't have the device near me right now, I will on Monday, but once I can, I will try the alcohol trick, it worked for my phone, and the keyboard dock. (BTW, I did blow into the USB port, and now the devices attached show up for 45 minutes - 1 hour before they disappear, and also, when connecting an SD card into the dock, it shows up, but on the case that the micro SD is not connected in the device (Dunno if it does this normally or what)
Just received my awaited elephone p9000 today and had been using it for a couple of hours setting up, Doing an update etc. When i came time to charge it. To sum it up it used the supplied usb c cable to attempt to charge it on multiple usb chargers and tried it with two pc's with no success. When connected to the pc it did come up with 'This device has been linked" Then immediately followed by "this device has been unplugged" Or at least something along those lines. Today i went and purchased a micro usb to usb c adapter and managed to get it to charge momentarily then to find it stop then start again. I am now sitting on 1% power and not sure what todo. Any advice? I have warranty on it from gearbest fyi.

When I first charged my P9000 it did not go over 50% until I updated to the newest OTA and rebooted the device after the last update.
But I have not encountered disconnects or anything like that.
You could also screw your device apart and remove the battery for some time, but as you have a valid warranty I would not recommend that.

If you connect your phone to your PC, is it listed in the device manager? If yes, does your PC recognize it as Elephone p9000?
Have you installed the latest drivers for your phone? (http://bbs.elephone.hk/thread-1037-1-1.html#.VWgkX_RAU-0)
Maybe changing the connection type in the notifications (when plugged in) helps in any way ?
Have you tried a different lead? I know this sounds obvious but my brother had a similar problem with his P9000 when he first got it, he used my lead (for some reason my lead was different to his as I bought from a different supplier, dunno why mines a kinda thick white lead, my brothers was a kinda thinner blue Elephone lead) and it worked fine. Although I haven't come across anyone else on here that's come across an issue with the supplied lead.

It does multiple things when it connects at different stages
ON and connected to pc- With elephone cable the phone constantly displays the messages 'Charger has been linked' and 'device has been unplugged' within ~1 sec of each other and no connection is noticed on PC.
With the MICRO USB - USB C adapter nothing happens
Powered off and connected to pc- Charging symbol will flash momentarily every ~5seconds. Pc will ding repeatedly as it connects and disconnects
fastboot- Somehow connects and is recognised by PC
Ive managed to get it past 30% power but took ages todo from leaving it powered off and just flashing on and off charging

I only have 2 leads unfortunately. The stock elephone and a micro usb to usb c adapter with a working micro usb attached. Ive ordered some more online and waiting their arrival. Im stuck on what todo
That is indeed very strange.
You could try to flash TWRP 3.0.2.1 via fastboot (http://en.miui.com/thread-58623-1-1.html, just use the TWRP for Elephone P9000 instead), but I would not recommend that as your connection is really unstable. The chance of bricking your device is much higher than the chance that your problem is solved.
If the leads you ordered do not help you should get it replaced.
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
