hi all,
recently, i found CM10 had been successfully ported to thinkpad tablet, but at the same time, my vol+ button was broken.
How can I boot into CMW without Vol+ button?
I tried "reboot recovery" but there is nothing change.
BR,
Ben

I suspect you're a little stuck without the relevant hardware buttons operational. The keypress sequence to boot into the recovery partition will be coded in the bootloader which is relatively uncharted territory. ROW devices are supposed to have an unlocked bootloader but you're a braver man than me if you tinker with it.
Is your device still under warranty? If so, you're best off sending it back for repair. Though I'm assuming that yours has expired since you're asking here. Even if the warranty has run out Lenovo would probably still agree to repair it ... with a hit to your c/card of course.
You could try disassembling the device yourself using the instructions in the service manual (http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/0a96158.pdf). Reports elsewhere say its not that difficult. If it's just the plastic mount that's broken you could attempt a repair or remove it completely and cycle the switch with a pointy device. If the switch itself is broken I hope you're good with a soldering iron or know someone who is.
Many thx, it is extremely easy to dissemble it..haha...i fixed it la...thz a lot!
One more question, my micro-usb also broken, can I buy a micro-usb to replace the broken one?

Your TPT has lead a hard life
Do you mean the cable or the TPT socket?
The cable is generic ... just look on ebay.
The socket will be specific to the TPT and not easily replaced. If it's just come off the mainboard you may be able to solder it back on. Otherwise, if the internal pins are broken you're out of luck. Talk to Lenovo ... they may be able to fix it for you.
you should be able to fix everything with a soldering iron
i dont know which usb connector they build in, i need to take a look but in general lenovo also need to buy them from somewhere so the chances are good that you will find a replacement connector somewhere at mouser, digikey, rs-components, farnell or somewhere else.
normaly the micro-usb is a SMD Component, so you can use a desoldering wick and soldering iron to remove the broken one, and then replace it with your new one.
i would not recommend to solder down broken pins, because mostly there is also a mechanical deformation inside the connector, so it will not work. replacement connector cost you about 1$...
if you have never soldered before, you probably need some help there, because SMD Soldering is very special and you can ruin your pcb within seconds if you dont have the right equipment and expertise!
edit: as far as i can tell from these pictures: http://www.wirelessgoodness.com/2012/01/06/lenovos-thinkpad-tablet-gets-an-fcc-tear-down/ the micro usb should be "easily" replaceable, seems to be a standard component...

Hi, I bought an XDA second hand and apparently they wont touch it under warranty. They claim its my fault and say I broke it anyway!
Now, it all works when opened like a laptop, however when I rotate the screen and fold it flat like the old XDAII, the touchscreen stops working.
If i rotate back to landscape mode, it works again.
Ive done a hard reset, and firmware upgrade so im sure its not software.
I assume there is a dodgy cable in the hinge, does anybody repair these, or can I do it myself?

Cable connector sounds loose - the cable is many thin strands so if it was a broken cable it would stop working completley. You need to diss-assemble the screen module and re-seat the push fit connectors. If the warranty seal is still intact contact the XDA helpline.

b4 u dissemble just try pressing at all the corners of the exec...u can get it working..
I took it apart, the connector was NOT loose
Now, it seems the cable is broken inside one of the wires.
Im screwed. I have a brick.

Can you see it's broken? Repair it with a bridging piece of wire. You can't buy the looms so unless you can repair the broken wire you do have a brick :-(
Use a multimeter to check for continuity of the wires.

My usb port has been flaky for a while but finally gave out totally recently. It's actually loose inside the case. Over the past couple weeks my digitizer has also been going bad. I read about how you can press the power button hard to get it working again, which works but it seems only a matter of time for that thing too. Anyone got any recommendations for what I could do? I ordered an external battery charger and battery but all it accomplished was frying my old battery. :/ I might try to solder a new usb port on once I have good reason to (read: solid mango wp7 rom.) but if my digitizer is done it's not really worth it. Why would pressing on the power button revive it when it's not working? I'm hoping it's just a loose cable.
Bottom line, does anyone who's had these problems (they're the two most common HD2 hardware issues afaik) have any recommendations for solutions?
Your USB port issue probably can't be fixed.. unless you can find someone who is willing to help you solder a new usb port to your motherboard (or you can do it yourself if you have enough skills)
As for your Digitizer, you can open up your hd2, and check if the digitizer plug is loose (located under the lcd). If it isn't, that means your hd2 digitizer is dead, and you should order a replacement.. (of course, please see here
I have the same issue with my Infuse. The digitiser only seems to have a problem for the four bottom buttons. They have a mind of their own. The rest of the screen is fine. My USB port is intermittant. I'll probably just take it back to the store though. Sorry I cannot help.
I have a Samsung Vibrant T959 TMobile US with 2.1-update1, Baseband T959UVJI6.
The battery is fully charged, it registers in the phone as fully charged 100%, but when I hit the power button I get a progess wheel that gets stuck, then the phone just turns off. It never gets passed that wheel, it only displays for a second then dies.
However, when I plug in the USB and hit the power button, it comes right up like it should. Then I can unplug the usb and use the phone just fine. Its almost as if I need to jump-start the phone with a power source.
I have reset the phone, even re-flashed the stock firmware using Odin. Same results. I have even swapped batteries with a buddy just to see if that was the case, but I still got the same results.
Any advice or suggestions is GREATLY appreciated. Thanks Very Much In Advance!
Anybody? Any ideas?
Well, that is new to me...
I'll preface with, I have no clue how/why that is happening. But, this is what I would do:
1 - If really opposed to rooting, I'd call T-Mo / Samsung and get a replacement.
2 - If I liked my phone and wanted to make it better, I'd root it and flash a custom ROM. It likely would take care of the issue, as it clearly is not a hardware thing (well, I say clearly).
Worst case with #2, ODIN back to stock and then do option 1.
possible solution
also it says "USB connected" even when cable is unplugged? I had similar problem.. I tried everything, flashing, changing batteries.. none of that was useful. Then I find some post on some forum that says it might be corrosion, so i scratched my USB with thin wire and everything worked fine, but also scratching USB I was doing one more thing. In my opinion, I think that it's not corrosion. I think that USB is slightly bent (middle part of it), try to bent it in other direction, possible that it's too close to edge. That solved my problem. Tell me if this helpful for you, sorry about my english

i think i can get what you are saying, cleaning the usb port on the phone right??
BUT how does this affect turning the phone on?? if usb port is rusty, it will only affect charging, not turning the power on?
I experienced this identical issue last fall -- the USB would always say it was connected, wouldn't startup unless connected to actual USB, but otherwise worked fine.
Take your phone apart and look at the solder joints on your microUSB port... mine all had cracks in them or had broken free. I re-flowed the solder while holding the port down and it resolved my issues. (put on some flux, and run a hot soldering iron across the joints, clean up... it's not very difficult. just be sure you don't short out any of the pins.) I also added additional solder to the four points that just hold the mircoUSB to the circuit board. It's been rock solid since

that sounds very difficult actually.. as I dont own any of the tools
anywhere cheap to recommend?

See if there is a TV or electronic repair place still in business in your area. Or post an ad on CL asking someone with knowledge and skill to do it. Be careful they aren't an idiot just wanting 20 bucks and happen to own a soldering iron.

you could see if Cell Phone Repair/ is near you and describe to them what you want to do.
I would go through these guys they are top notch helped me when i soft bricked my wife's phone. He even convinced me that i could fix it myself when i was ready to send it to them for a jtag.
They can replace the usb plug if thats the issue.

I would test to see if my battery is bad first before i went about resoldering, it could easily be a bad battery.

thank you for the response. I definitely think the usb port is an issue. what is a jtag? haha

No my stock battery is charging and i did buy a separate battery. same issue.
Hello! do not work volume keys and may not enter into bootloader, operating system does not loaded, tried to rearrange the firmware and then it gives an error that this firmware is not compatible for this version of the hardware device. Cable with side volume keys is work! the problem with the motherboard, how to install the OS on this device? I would be very grateful for the help!
i guess you have to have your HD2 repaired first as the software is dependent on a good working hardware.
Can anyone knows how to cause butloader without side volume keys? or can someone already had this problem and knows how to solve it, please share experiences
Well, i guess you can take apart the HD2 and then try to start it into bootloader mode by prying off the volume tape/contact dome from the volume down contact and then shorting it with a piece of metal...
I tried to remove the cable and multimeter test button and cable, they were working, the problem is on the board

It is also possible to be a faulty connector on motherboard or even some contact on main flex ribbon in same connector area.
yup ask someone who can open the device to check it
He is now in the the best master of our small town. I think that on Saturday when it will take will still try to disassemble and repair, I will write here on Saturday. Thank you all!
I have a OnePlus 5 with broken usb-mic connector on the motherboard (FPC). I'd like to restore the charging functionality and, at best, also the usb (data + data -) line. There is a schematic for the FPC pin assignment? There are other place on the board where I can find 5v,gnd,data+,data- line (maybe a jtag or a service hole/plate)?
I also have a spare connector but there's not enough space to re-solder and some plates are gone with the broken connector, so I'd like to find an alternative way.
Thanks

Honestly, resoldering would not help, and since are pretty much left with no alternative but burn chunks of money, I don't know what you expect from here?

I can't understand what You're talking about.
The question (I suppose in the correct section) was easy: There are pins or plates (except the fpc connector) on the OnePlus 5 Board to power it?
For the pourpose I have in mind (a Tasker bridge device) the solder solution would be great, if possible. Seems strange that in the whole board there's not an alternative +5v and a GND to power it. But, after a week and with only Your (non contributing) answer I think I have to get the circuit tester and route some points myself.
I'd rather prefer no answers If the only one I get is about the circumstances and not about the point.
Thanks anyway

Sorry to say if you see it that way. I know what I wrote was correct, and I was just resonating your point that there is no way out. Not sure if you seem to have seen it differently and rather why??

There's always a way out, maybe it could be difficult or expensive, that's not the point. We're talking about a connector, not a more complex component.
Banally, the first way is by following the 5v from usb cable to fcp connector, (as described in a youtube video about OP5T) and check if that plate is still there, then, if not, if there is another point of the same line or a scratchable spot.
The question was about existent schematics and/or other people experience about this or similiar. Things that can make everything easier or confirmed.
So:
- The "repair" is achievable? Absolutely Yes if the fpc plate is not damaged (by making a bridge); probably Yes if damaged.
- The "repair" makes sense? Yes, for my purposes
I can't see Your point and Your statement, as I already know there's a way (that I've asked to be confirmed or already experienced) .
