So.. here goes my problem..
Got my Qtek 8310 three days ago, and the very same day I got it, decided to upgrade from WM5 to WM6. However, the battery charge meter gave me wrong info about the battery charge percentage, and the phone battery died just after I formatted the BINFS and re-setted the device in TeraTerm.
The device still powered on, after each USB cable re-insert, but died, after 5-10 seconds. After a couple of attempts, the phone didn't turn on at all.
Did some info search on the web and found out, that my battery fell to an critical voltage level. Li-Ion batteries require a certain voltage to even be able to accept a charge.
As I got an non-original battery (Sanyo ST26C) I suppose it is poorly designed and doesn't have good under-voltage protection (I have read about other HTC models (e.g. Wizard) having this problem as well), so the battery dropped below these limits and phone now identifies the battery faulty and doesn't let it charge. This is for consumer safety, because attempting to charge damaged Li-Ion cells can be dangerous, as Lithium is known to be able to catch fire/explode.
So the phone doesn't let to charge the battery in any way (1amp wall charger or USB cable).
Anyways, I tried to jump start the battery (charge with bare wires) to give it initial charge and... it worked. However, there goes my main problem: As soon as I insert the battery which has the initial charge, the phone starts immediately and boots to a bootloader (as there is no OS, formatted BINFS) and the the phone does not charge while in bootloader.
Then, I tried to turn off the phone: Hold down power off button for 5 seconds - phone turned off. But as soon, as I release the button, red light flashes once (as it does everytime, when you try to turn on the phone, it's normal) and then orange LED comes for a second, indicating a charge (as the battery is no longer considered faulty - phone lets it to charge), BUT then phone starts again to the bootloader and it somehow prevents further charge.
So: as soon as I release the power off button, after the phone has shutdown, it starts again, everytime, and soon the battery dies again.
My own thoughts of solving this:
* Get a fully charged battery from a friend, install the windows on the phone, and then charge my own battery (I know noone, who may have HTC Tornado, will be hard to get);
* Buy some standalone dock charger, which can charge batteries directly and charge the battery happily (haven't seen any around yet, so will be really pain in the arse, to get one);
* Charge battery with bare wires for an extended period of time, to give it enough juice to install windows (which I strongly doubt, as battery damage could occur);
Any other ideas? Ideas and comments, from people who know, or had similar experience is more than welcome. Looking forward for answers
Its funny. Reading you I've realized what people tell me about "I make a question and I answer it myself" So... You have the answers my friend. For options 1 and 2, use E-Bay. As a matter of fact, there is an aftermarket charger in ebay that charges your phone and a spare battery and it includes the spare battery when you buy the charger. I believe it runs for under $20.00. For option 3 use some wood cloth pins(those used to hang cloth to dry). I would say with at least 2hrs charge you should get a good 50% charge on your battery, enough to flash your phone.
Edit: Here is an Ebay Search. But, keep searching till you find the one that includes the extra battery. Chances are your battery is no good or won't last you very long.
Good Luck!
Get a new battery man, these li ion batteries, are no joke, especially the fact that they are made in China/Taiwan, I myself had used a tornado battery even till the days when the battery has bloated and cracked the back cover, when a single charge could not even last 4 hours.
Those days, were like having a timebomb in your pocket, ended up I got mysel a new tornado at a price cheaper than a replacement battery.

Well yes, I have some suggestions, but I am also expecting others to have some, too. And by sharing the knowledge, maybe I could prevent myself to spend more money on this issue

The main problem with e-bay is... my country. at least 80% of the items, don't ship to my location.

Thanks for the suggestion. The main reason why I am in serious doubt about this option, is that standard chargers usually have some sort of regulators and monitors the charge, prevents from overcharging, etc. But on the other side, USB charge output is only 100 mA, so it couldn't be that bad if you think about it

Well, the fact, that it is manufactured in China actually says nothing Many companies choose China to manufacture their products because of low costs. And the most of electronics is manufactured in China and other Asian countries.
Anyway, before getting myself an new battery, I would like to try resurrect this one If this won't last long for me - no problem, I will get an new one. But until I'm convinced enough, it's a waste of money, which I don't like doing
And one more thing.. maybe someone knows a way to keep the phone power off?
Because as I said earlier on, it's charging only when it's turned off, and not in the bootloader. And problem is that, as soon as I put the battery, it starts-up the bootloader.
Get a desktop charger perhaps?
Or if you are adventurous enough, mod the USB cable, and charge the battery directly, only if you know what you're doing, and only if it works

Well.. thanks for the answer, but we've already discussed this option and now I am asking whether or not, someone knows a way to turn off the phone and keep it turned off (prevent from self startup) while the phone has no OS (got formatted BINFS).

I've already done that, and yes, it works. But I need someone to confirm, if it is safe enough to charge the battery for an hour or two.
Have anyone tried that?
I don't think that it's very safe. But I was having a similar problem, and I just left the phone connected to the power cable, and even though it seemed like it was not charging, it apparantly was.
Or you could just get a new battery. On expansys I saw a new one for ~$20.

Well..
With a modified USB cable (bare wires), which got power output of 100mA I have charged battery directly for approximately 3 minutes, and the phone turned on, and was operational for 4-5 minutes until the battery died again.
And before that, I've tried leaving it on an mains charger, which got power output of 1A (1000mA, 10 times USB). I left it for a hour or two, although no led was showing up to indicate a charge. The phone didn't event turn on after this 2 hour "charge".
And the reason for this is explained in my first post. Will try to leave it charge over a night, though, expecting for a miracle

But new batteries usually come empty, so it's no use to me. I have also explained why, on my previous posts.
So before buying an cradle charger, I would like to find out if these budget-friendly solutions will work:
1) Find out how to keep the phone powered down (because it's the only moment, when it truly charges);
2) Find out if it is safe enough to charge battery with bare wires for extended period of time (1-2 hours);
Just came up with another idea. Searched the forums and found a very similar problem to mine:
fritzgerald said:
For some odd reason my wizard likes to say the battery is full when its actually dead and that it's dead when it's really full. Well a few days ago I was reflashing to try and take care of the issue and it died during the middle of flashing. It would only goto the bootloader screen and would not charge. Well I decided I'd post a few pictures of my recovery technique utilizing my wife's phone. Cat5 cable striped at the end and twisted to each of the positive and negative battery terminals and the Blackberry's battery put it so I could use it to power the wizard.

So.. I've got a Sony Ericsson w810i, would this technique work? The w810's battery is Li-Polymer, 900mAh 3.6V (although some sources say, that this exact battery is 3.7V..), compared to Li-Ion 1150mAh 3.7V Tornado's battery.
Voltage seems suitable..
Haven't got any answers to my previous posts, so I tried.
The trick worked, Sony ericsson's battery can feed HTC Tornado perfectly. However... got another problem..
Here's how I wired it up. The positive wire takes two contacts and the negative takes another two aswell. The ends of the wires are then connected to the sony ericsson's battery. Phone starts, and boots to a bootloader. Everything's seem to be perfect.
Then I plug in the USB cable into the computer, the other end to the phone. Phone recognizes the cable and puts label "USB" at the bottom of the screen.
However, there's something wrong with the connection.. TeraTerm fails to connect and Update ROM utility fails, too, with an "cannot connect" error..
After that, I have tried using the original battery, with no wires attached, just plugged it in (gave it an initial charge again) and the USB worked without any problems: TeraTerm can connect.
So the problem seems to be in wiring.
I have tried to connect the wires in different random ways (crazy, I know), but only one alternate way did worked. Although, phone did heat-up rapidly at the area, where it says "HTC Innovation" and phone's display showed "USB" even if no USB cable was connected.
So.. looking forward to some thoughts or any knowledge, of why is this happening, wiring schemes, or any other suggestions..
FINALLY! SUCCESS!! I've connected the wires from the sony ericsson's battery to touch only one pin on the phone, instead of two, as shown in the picture. The phone didn't turn on, as I've tried this before.
But then remembered that the same pins charge the original battery, so inserted the battery and VOILA! Phone turned on to the bootloader and the USB circuit wasn't blocked no more! Flashed the phone to WM6.5 now successfully and the original battery is charging, as I write this post )
So, if anyone got HTC smartphone dead, while flashing, let me know, will try to help you out, since I've walked through this hell myself

1A Wall Charger Works!!
I've had the same problem discussed above. I was trying some of my own 6.5 ROMs, which by the way were getting stuck at the initial boot screen itself. Due to some unavoidable reasons and circumstances, the phone freely was left to itself at this exact state, untethered to any power source, for extended periods of time, during which it slept and refused to wake up again, all my pleadings going in vain. And when it did boot, it went into the tricolor screen conveniently and switched off in ten seconds. I turned to the net for help and found that any charger with rating above 1A would help in giving it the required juice. I didn't want to waste any of the 6 USB cables I have.
I got the original charger, which is an 1A charger, after 2-3 hours of searching my room (Hey, Don't be too hard on me! In the end, I got it, right? Actually, I use the PC for charging, and a smaller 550mA one sometimes-- both didn't work this time) and then, when I connected it showed the screen again. But this time, I found that it was capable of running it without the battery being present.
So, all I did was I kept the charger connected to it with the phone switched on in the tricolor mode and with the battery inside. After half an hour, I tethered it to the PC and flashed a proper ROM. And Voila!!! IT WORKED!! It was 2.45 in the morning!!
I guess the power from the 1A charger is enough for the phone to run and charge it too which is not the case in the 550mA one and the USB cable.

Glad to hear that it worked for you Unfortunately, it didn't for me (as I only have an after-market charget, not the OEM one, although it is 1A), so I had to search for alternative methods.
I got my sgs2 about a month ago and its been like a dream, battery lasts for a long time phone runs ultra smoothly no glitches and nothing weird has been happening, but these last few days its just been really weird.
1) it started randomly going into driving mode, i dont even know how to activate it or what it does, but i think its draining my battery
2)When i was watching a tv show on my phone it thought that there was an hdmi cable connected and wouldnt let me hear anything through my headphones. i exited it several times but it still though there was a cable connected. Then i went straight home and quit it from the task manager and it worked with the headphines but that might have been a coincidence.
3)When i connect the charger it takes a while to realize that its charging and sometimes stops charging and says that the battery is too hot or too cold but when i feel the phone it feels completely normal.
4)When i connect the usb cable, other than taking a while to realize that its connected to a charger it doesnt realize that its a usb so i cant transfer files with my computer which i do often
5)I pressed home before and it took me to some sort of clock which i imagine is for a dock but i have no such thing
6) Even after using the phone for a while and using several apps the android os has used 59% of my battery, when usually its the display that uses about 30 or 40%
none of these things had happened before and now they randomly started all at once, i havent downloaded any shady apps so i doubt its malware
any ideas?
thanks
Are you using a stock firmware or custom?
Have you tried resetting back to factory default?

seems like majority of your problems are linked with the micro USB port, try resetting your phone and see if that helps. This is weird though.
It happened once to me on my sgs but that was because I inserted the charging pin without realising it was wet but it went back to normal a few days later and I changed my charger.
i was also starting to think it would be a micro usb problem,
would a factory reset fix it?
if so how would i back up my apps so that i have the same apps with the same progress on them, is it even possible?
or should i just wait and see if it goes back to normal?
I am also having this issue now. I've tried a factory reset with no effect. The phone is now largely unusable. Did you get a resolution? If so, how?
im having the same problem too .. wish it's just a software issue!!
the problem solved itself after a couple of days, i took out the battery and left the phone alone for about a day and after it worked fine again, not sure if it was the time or leaving it without battery but its working normally again
I'm having this exact problem - phone switches into driving mode, then says MTP is connected - then it switcheds to a strange lock-screen I have never sen before. It's really strange. I flashed a nandroid backup from a few months back and still the problem is there. I'd flash back to stock and send it in - but I can't connect to Odin via USB because of the problem. Is there anyway to convert a Stock rom to a CWM flashable file?
I'm desperate to get this sorted.
Experiencing the same. Has anyone a proven solution for this?
My phone, sorted itself out - should I say my wife sorted it out - by mistake. What I think she done was hold down the home button, and then pressed the power off button together and held them untill the phone switched off. When my phone came back on again - she had somehow removed the -Exclamation Triangle of the kernel counter and removed the problems from this post - that I'd been experiencing for abouyt 5 months prior.
Go figure - I now have a SGS2 that works beautifully again and has also had any kernel counter and Custom Rom flashing notifications removed altogether. I wish I knew why this worked, as I'm sure their are many who would like to remove the Triangle without a jig.
The other option that seeemd to work for other people was to clean the MicroUSB port of the device with a dry, clean toothbrush - though this did nothing for my problem. Good luck -I know how frustrating it is.
Help Please
Guys, I am Facing the EXACT same problem.
1.Driving mode on/off automatically
2.Showing a lockscreen which shouldn't have existed on this planet.
3.Hanging up unconditionally. Have to restart phone.
4.Sudden "mtp connections" and because of that "Media Scanner"
I own a Galaxy note just 1 month old! I was so angry that i wanted to sell this. But i couldn't adapt to any other smaller screens so, guess ill try fixing this.
1.It definitely is something related to usb port (Since i cannot charge my phone, i use an external charger)
2.Took my beloved to a samsung service centre, they said phone is waterlogged and showed me the motherboard, saying"IC MIGHT be damaged"
3.Cost for repair - $200
4.Cannot afford that. I am guessing they were bluffing cause i saw the shiniest motherboard ever
5.Please fix this, or ill be stuck with a Nokia 500 !!
6.I can, however afford changing the usb connector, anyone successful with that?
Edit: Did my homework and found out that its definitely a usb port problem. Solution:Clean the usb port. Ill try try it and get back to you ppl. Oh and about 20% of the world's population is facing the same problem.
Edit(2): SOLVED!!!
1. Turn Off phone
2. Remove battery.
3.Take a Brush with hard bristles(Toothbrush/Artist's Brush)
4.Take a pin.
5.Take your own sweet 15mins to perfectly clean the micro usb port using the brush. Nicely and Tidily, give all possible strokes to flawlessly remove any dirt in there.
4.Then take your pin(Be careful here) and gently insert it into the gap between that small metallic micro slab and the bottom part of the usb Connector and gently move it up, VERY GENTLY!!!
5.Clean the battery's charging plates using a cloth, i used my own T-Shirt.
6.Put battery in and REBOOT.
7.Clean the charging pin of the charger using the safety pin/Brush or both.
I have it on for 15mins and no problems. Removed and put the charger again and again, still no problem. After waiting for 1 week, i am able to charge it using its charger! Now lets see whether it lasts......:-/
Edit(3): So, my phone acted up again last night, with driving mode and car dock. I used the pin solution, No problem till now. its Peacefully charging. Bah! it really is annoying
Edit(4): Now, its been 24 hours since my last solution, and phone hasnt acted strange. I guess after another 12 hours ill rule out the permanent solution. Which i used.
same here
Well.. I'm having similar issue. Battery drain and random driving mode/voice search sometimes. It all started after last OTA update and rooting without changing a ROM to custom. I've clean out USB port and no result. Maybe it's time to scan system with AV or unroot device...

I had the same issues 2 weeks after i bought my galaxy s2. Took it to Samsung customer care and they replaced the micro usb port. Haven't had a single issue since.
PS: Try to dry out the port and the phone if it is a water logging issue. I used a hair drier to do that. Luckily the tab that indicates water damage hadn't changed colour.
Had same issue with my Samsung Galaxy Note - randomly going in and out of driving mode, used a dry, soft toothbrush to clean out the USB Charging port, so far so good.
Make sure to flick the bristles of the toothbrush back and forth with your thumb first as you might see a lot of dust fly off of it.
Don't use anything hard like a pin or needle as you might scratch the contacts.

It's just a software problem, the reasons might be:-
1) you might have opened and closed some huge apps randomly and very rudely..
2) You are low on space on the internal MMC Card
3) Your phone might be performing the restarting apps re scheduler
Solutions:-
1)Factory Data reset will not help as the cache section might be corrupt.. neither the android 3e will help...
2) a)Use odin and download the Latest firmware package from Sammobile's Website.
b) for tutorial on flashing, go http://forum.xda-developers.com/showthread.php?t=2488942.
c) Do not touch the phone after processes and restart was observed...
d) Again get into download mode and re flash the same Firmware again...
e) Restart the phone holding the HOME key, (it won't do anything by itself)
f) it will surely fix your Phone
3) Message me if any problem persists...

I registered on this forum just to say that this is a great solution. It looks like my phone is saved now
Hope it will not happen again.
Hi guys,
Been having issues with charging for the past couple of days. When I plug my phone into the charger it states that it's charging, but nothing really happens. The troubleshooting so far:
Have tested it on multiple different chargers, all having same problem. However, my Nexus7 tablet will charge normally on these chargers, so we can rule out it's charger related.
Tested for differences with the phone switched on or off. When phone is switched off it will charge, but not with the speed it normally does.
Running CM11 Snapshot M9. Did a clean install. Battery does not charge normally (read 1% gain per 20 min) on most stripped down version (without gapps + personal apps)
Looks like it's battery related. But I find it difficult to rule out what's causing my phone to act funny. The weird thing is that sometimes my phone will go for a decent charge, but this happens so randomly that it's hard to find any form of sense in this process. Also, when the phone is on and charging, the battery light will sometimes turn off. But when I activate my phone again, the battery light will bleep on as if nothing happened and everything is functioning normally (which is clearly doesn't).
Does anybody have an idea how I can fix this? Any helpful tips that can point me into the right direction to figure out what's causing this? Many thanks in advance!
did some more testing - can anyone help me out?
After some additional testing I'm fairly sure that it's either battery or chip related:
USB debugging does not work at all (storage is set to MTP). When I open Android File Transfer my Mac will recognise the Nexus 7 tablet, but not the Nexus 5. Debugging is switched on in Developer options.
When I try to use adb or fasboot, my device is not listed either, nor are any commands (directed towards phone) executed through bootloader.
In the about Phone section I went to check the Battery info. It will state correctly that the phone is being charged through AC or USB (depending on wether the device is connected to laptop or charger).
Does anyone have an idea how I can figure out if it's chip or battery related? I desperately want to find this out, because I bought my phone in The States and live in Europe... So in the worst case scenario the phone needs to go back to the US due to bureaucratic policies. Already had to go through this horrible proces half a year ago with a bad NAND chip, really want to avoid the hassle and lose my phone for at least a month. So if it's a battery thing I rather order a new one and replace it myself
Really really hope someone can shed light on this issue, running out of luck and options. Please guys, please :angel:
sounds like the usb connection, physical, is going. if it doesnt charge but randomly will, fastboot nor adb see it, i think its an usb connection issue. i had the same with my nexus one a long time ago, if i wiggled the the connection when it was connected, sometimes i could get it to charge some. fortunately, it isnt an expensive repair, and yours should still be under warranty.

Thanks for the reply, really appreciate it How much you reckon it will cost? Also, can I do this at any decent phone recovery shop? As stated previously, really want to avoid sending the phone back to the US. Once again thanks!

i paid $35 3 years ago(?) at a local repair shop.
@simms22: ordered a USB portal online and replaced it by myself. Phone works again. Thanks for the tip!
I've been enjoying my TF300 since the month it was released, but in the past few months the battery stats have become less and less accurate. I was watching YouTube videos on it while it was docked and charging yesterday when it suddenly died, and I haven't been able to get it to boot since. Sometimes it will start to boot, but die half way through the boot animation, which implies that the battery isn't charging.
When I plug the charger directly into the tablet, it flashes orange twice and then does nothing. When I plug the charger into the dock, that shows green - so I assume the dock is fully charged. When I plug the tablet into the dock, it flashes red twice again.
The logical assumption from this is that my TF300 has stopped accepting or holding a charge. My question is, which part do you think I should try and replace first? I understand that the dock connector has separate pins for 5V and 15V charging, so maybe that's been bent or broken somehow...or the battery itself could be worn out...or the motherboard could have developed a fault. Has anyone had a similar experience to this? I don't want to buy a new tablet as there is absolutely nothing wrong with my beloved Transformer other than this!
I'm going to leave it plugged directly into a standard PC USB port for several hours tomorrow while i'm at work, to see if it will trickle charge that way. That would imply the charger is at fault, despite the green light from the dock when it's plugged in.
sort of same here
My thoughts are that the one battery is no longer seen by the tablet and the other is getting too much of a workout as a result.
We have possibly just lasted beyond it's expected lifetime - which is kind of dissappointing. I don't understand exactly, but we might troubleshoot this still.What rom or Firmware are you using? I am on straight CM11 with no other modifications. I am using the tablet docked al th time and th rom "sees" the two batteries but dies at about 50% of the one without touching the other. I'm pretty sure that it really only is using the dock battery and never seems to go to the tablet battery anymore. Wish I could fix it - will try to use it without the dock and see what happens.
It was running KatKiss 5.0.0 - I kept reminding myself to go and download the latest update but never got around to it.
After leaving it plugged into a standard 800mA charger all night and all day, it booted for about 20 seconds and then died again before it reached the lockscreen. It seems that the battery is either charging unusably slowly or not at all. I may have to start hunting for a new convertible!

Well mine is working fine disconnected from the dock - so it sees the Tablet battery and uses it now; I will use it until it needs charging and then try again - by attaching the dock and charging etc. Will yours work if just plugged in? - like a laptop with an old battery, does it still work but you are tied now to the power supply / charging cable? I have installed the latest "homebrew" Omni now to just get a new start on things and will continue to just use up the battery and see what happens next. My preference is to have vanilla CM but it seems the tablet battery was invisible. I hope by re-setting things and having a new Rom in place will give me a clean slate.
Sadly no, it doesn't run even when permanently tethered to the power supply. I think the battery has to report a minimum state of charge before it's allowed to turn on, and that's where it's failing in my case.
Batteries are back
I wish that I could tell you how - but I can't - the batteries are back to full functionality. I will tell what I have done and this might possibly help. I installed Omnirom with Lollipop and it worked but was very slow. Then I installed CM 11 back (then CM 12, then CM 11 again all with the appropriate GApps & SuperSU etc.) and it seemed to put things back in order. I did also install a battery calibration app which just deleted a file tracking the battery(s). Some where in there the batteries starting working properly - this involved more than a few re-boots and re-installs (dirty and clean). In all this mess lies a possible solution or maybe it was when I slammed it shut in frustration - this could all be due to a loose wire/solder joint too. The battery is following the "normal" process now of first draining the tablet battery to ~ 80-90%, switching out to the dock battery, then switching back to the tablet when the dock is drained fully.
@kjwaugh
I can't recharge my battery and I have CM-11-20150112.
My little led never turn on orange light.
My question for you is: Does your led turn on when you plug in the USB cable ?
I'm afraid I have broken some analog circuit inside the tablet or, I hope, only the cable.
Please let me know.
Hey All,
i have a nexus 5 running android 5.1.1, which recently i have encountered some battery issues, the battery drained very fast (6-7 hours from 100% to 0%).
but then, it stopped charging the battery, no matter what i changed - nothing worked! (new cables, different chargers and so on).
yesterday i have bought a new battery and replaced the original faulty battery, but nothing is changed, the new battery won't charge.
i tried to charge it when the nexus is on or off, doesn't matter, same result...
i am very frustrated from the situation, and basically can not use the nexus any more..
one more thing, i tried also google suggestion (when the cell is off, to press power+volume buttons, and then scrolling down to shut down and inserting the charger - >didn't work for me).
i tried to upgrade to Marshmallow (6.0.1) but there is not enough battery power to allow it...
when i dial *#*#INFO#*#*, and check the battery properties,
why the temp is always -30 degrees for the two batteries?
Is it a sensor issue?
do you have any suggestion?
Thanks!
anyone?
i will really appreciate your suggestion..
Connect the phone to a Windows machine and look to see if any new devices appear in Device Manager.
Thanks for the reply.
I connected the nexus to my laptop, it was recognized and i could reach the storage, but the battery remained the same, not charging ..
So the nexus 5 appears in Windows explorer? Possible charging port problem?

well, maybe. havn't tried it so far..
have you encountered this issue of wrong temp alert of -30 degrees for other users ?
and replacing the charging port solved it?
I haven't encountered the battery temp issue.
Since the old and new battery behave the same way, there wouldn't be too many culprits which is why I mentioned the USB charging port. Has the ever been dropped? Any way you could test the batteries in another phone?
the problem was resolved!!!
finally, after so many hours trying to make it work, i encountered a thread here in XDA which explains that the sensor is located on the cable connecting the battery to the motherboard.
Apparently it was a bit loose, so i put something above the connection and put the cover tightly.
then, the temp was reasonable again and my nexus was coming back to live!

Same problem

Hey, I have the same same problem , what did you do to fix it? I've been almost a year without using my nexus because it only works when it's plugged. Can you tell me what thread did you read or the solution? Thank you
See my last post....
Anyway, The problem was at the connection port of the battery - when you remove the nexus cover, you will see that the battery is connected by a connector with 9-10 pins to the board. Apparently those pins weren't connected properly and were loose, so I put something from above to make some pressure on the connector, then screw back everything and close the cover. Since then, my nexus is working great!
I hope it will work the same for you...
