The battery is fine. I had one more Tornado device the same happened with it stopped working the same way i replaced its battery but it didn't worked.

Oops - I hope there is no sudden death disease for the Tornado?! The only part that is usually mechanically stressed is the USB socket. If you dare to disassemble the device and you get through until you have the PBA in your hand, then you may check for the soldering around the USB. It is a plain normal mini-USB with only 5 connections, so re-soldering is not that difficult for a skilled person. It is worth a try - as it seems dead anyway.
Take care about the keyboard connector - of all the Tornado patients I had on my table most had their keyboard flex cable ripped - this cannot be repaired and you need a new keyboard PBA.

Its no trouble for me to disassemble the device. I'll check it right away, and thanks for quick reply's

The USB looks fine, but i'll get it re-soldered from the market tomorrow. I hope it works Thanks for your help tobbie =)

That's strange - if it looks ok there. Maybe the battery connectors then? Usually these are not much stressed - so I have no other idea. Good luck!

@tobbbie
Hey, i checked the other Tornado device i have, i think its got the problem you mention that USB one, if i exchange the usb port of one device onto other will it work?

this one can go itno the bootloader screen too, and if i switch it on the T-mobile screen comes and it keeps restarting.

Re-soldering works if the contacts are gone off the PBA. This could be any of the USB contacts (+,-, data-wires - in total 5 connections + metal frame of USB) with different effects (not charging, not syncing). Restart should not be an effect - do a hard reset on that device (l+r softkey method when switching on). If that does not help, then flash a new OS only. Do not deal with flashing the bootloaders (i.e. a standard flash image) - if you mess anything there (because of USB problems) - the device will be dead.
Taking another USB should not be necessary. This can hardly break and removing it from both PBA may ruin the PBA and the USB socket - so permanently killing both.

hmm that means i need to get the USB repaired and flash a new OS.

i've got soldered a new USB onto the PBA from the market not the problem is that The phone restarts after the first bootscreen. and if i connect it with the pc for flashing the terterm pro doest detects it. And if i try the hard reset the reset screen comes but turns off automatically. Now what to do =(

Seems like you need to bury that device - or keep it for spare parts :-(

It's probably ROM problem, if your phone restarts on T-Mobile screen. Try HardReset from bootloader mode, or reflash your phone

damn
@gutek85
how do you hardreset in bootloader mode ?

[Q] How to fix short circuit motherboard. Need help asap!

Hey everyone as the title says, i think i short circuited my htc one x motherboard and now its not taking charge.
I saw the project on wireless inductive charging for htc one x using the palm touch stone and the receiver it was and easy make but before i was about to i was testing out the pogo pins to see which ones were for power, audio etc..
So i stripped the jack of one of my old 3.7 volt chargers to get the plus and minus wires and it placed them on pogo pins 1 and 5 ( i know, what the hell was i thinking )
Anyway, pogo pin 1 sparked and the phone had lost power. Luckily it restarted as normal but when i put the phone to charge it wasn't taking any. I thought it was the battery but wen i connected the phone to the computer it wasn't recognizing the usb either.
btw the battery still has charge in it so i need help before it dies please thanks in advance.

Although probably easy to fix, I would have to say in the long run you would probably be better of just updating/upgrading to a new phone unfortunately..... something like that will probably keep giving you issues down the road. I wish you the best on fixing it though!
(maybe "drop in the toilet" and send it back to get fixed?? :laugh:

[Q] Water Damaged Nexus 5 Boot Loop Suggestions

Hi all,
First off I would like to thank anyone and everyone that reads this thread, it helps me out if you have any information that could help me out here.
About a week or so ago my girlfriend dropped her Nexus 5 in water, and removed it almost immediately then brought it to me. Sadly the damage was already done and the screen was black. I got the back off and got as much water out as I could shake gently, and the screen still had haptic feedback when I touched it, so I messaged it and it displayed the notification light. This led me to believe the battery was ok, so we left the back off and let it dry for a while, and over time the screen and sound came back. We placed the phone overnight in dry rice, and for the meantime we put her SIM in an old S2. The next morning there was obvious water damage on the screen but less than before, and everything seemed to be working fine, games ran, music played, messages came and went on Hangouts, and when we plugged it in to charge it worked like a charm, so we believed we had gotten lucky, put it back in the rice overnight again and the next day tried putting the SIM card back in the phone.
The Nexus at this point asked to restart and we obliged, but this is when the problem started. It would get to the Google boot screen, hang, then restart, over and over. I tried going into recovery and I could, but no further than that. I am not an expert so don't know what would cause this, but I am led to believe that the battery and everything else is all in working order otherwise it wouldn't have been working and charging while it was on. I wonder if maybe there is a separate part of the phone used for BIOS bootup and it got damaged? Any suggestions or ideas on how to fix the issue would be met with extreme gratitude. Thanks for reading all this.
TL;DR Phone was dropped in water, aired out and worked fine, restarted for SIM card and get stuck in endless boot loop.

Take the device apart, remove the motherboard. Get some rubbing alcohol and a tooth brush.
Remove any shields that can be taken off to expose more components. Then start scrubbing!!! Continue until you get all of the green/white corrosion. If there are any black scorch marks on the connections, take a eraser and it will remove the burn mark, then continue to clean with alcohol. Also the flex cable connections would need to be cleaned also.
The next step is up to you, if you feel comfortable with it. Make sure all plastic and rubber pieces are off the motherboard. Then stick it in the oven on 400F for 30 min to reflow some of the solder that may have gotten damaged.
Put back together, you may have to factory reset if the software got corrupted.
It is still highly possible to recover the device.
Good luck!

I wouldn't go so far as reflowing solder for a dry-out.
http://www.amazon.com/o/ASIN/B000BXOGNI?tag=adapas02-20
can be attained at your local auto supply, simply disassemble the boards and give them a once-over spray and wipe-down. Reassemble, and then troubleshoot the bootloop, which may require a full stock flash. Good luck!

I am not reflowing to dry it, sometimes solder on the connections/components need to be reflowed when they got WD or the device will not function correctly.I have seen it more time that I can count.

There wouldn't be solder damage when OP acted almost immediately to dry it out. A cleaning, further drying should be all that's needed. One should NEVER turn on electronics until fully disassembled, cleaned and dried in any event.

The second the device hits air corrosion starts to build. Rice does nothing, it pulls a little bit of the water from the charge port and headset jack, basically what drips out. There is possibility that there is still water inside the device. He needs to open it up to scrub it down with a tooth brush and alcohol at least.The connections may break in time even after cleaning, that is why I suggest a reflow.

I don't disagree most of this up to the point of reflow, which should be an absolute, last-ditch exercise. If corrosion is a major concern, after cleaning with solvent, a Caig deoxit treatment would be my next advice, but I think reflow is best left to the experienced.

Thanks to both of you for your advice on this. I will go and get some of the cleaning spray you suggested and give all the components a good clean, and will look for any scorch marks that may have occured when it was damaged. I would try flashing the OS as well but I'm not entirely sure how to do that when the phone has not been set up for USB Debugging. I attempted to flash it after unlocking the bootloader, but that didn't seem to work either. I will report back when I have performed the steps and let you know if there has been any progress.
Thanks =)

Damaged daughterboard connector from mainboard. Data still recoverable?

Hi all,
A follow up to my enquiry here about a badly damaged phone: forum.xda-developers.com/google-nexus-5/help/transplanting-main-board-data-recovery-t3253789.
I ordered a second Nexus 5 with the intention of transplanting the first mainboard into the second body, only to discover the first motherboard has a damaged daughterboard connector from the initial accident. The daughterboard connector/pins (?) aren't attached to the mainboard anymore. Photos here (that's the disconnected socket/connector next to the board):
cl.ly/142v473d2s17
cl.ly/33461J0K1Q2d
cl.ly/2S190F1v2M2c
In spite of the missing socket, I actually tried connecting it to the rest of the phone and powering it on anyway - no luck however. Didn't budge after holding down the power button. I can confirm that the rest of the second phone works when I plugged it all back together with it's mainboard.
Questions then - is it possible for a professional (presumably) to reconnect this and get the board back up and running? Or is my motherboard and data completely gone at this point?
I realise the solution probably won't be cheap at this stage, however I really want to recover some of the data off that phone and I'm just hoping that's in some way shape or form possible.
Thanks for any advice. Having a bad run of luck and really hoping for a bit of a holiday miracle with this now...

Hi
Sorry for your problems. To help yourself understand how your Nexus 5 hardware is put together you should take a look at the youTube video posted by LE55ONS "Nexus 5 Teardown" -. Just do a search for LE55ONS in YouTube. He has posted many very well made videos on how to repair smartphones.
It will show you every aspect of the hardware.
I hope that helps you

Thanks but this doesn't really address what I've asked regarding the damaged connector.

I would say, in theory it should be possible to reattach that connector with the proper reflow equipment, but it rather depends on how much damage was done when it was pulled off the board. If it is just the solder that let go then not so bad, but if any of the copper pads/traces on the main board stayed attached to the connected when it got torn off then it becomes a much more difficult repair. The puzzling part is even with that connector removed you would think the main board would still be able to power up, with obviously the ports attached to the flex board not being available so that makes me wonder if perhaps other damage has been done to the main board? You could confirm this by seeing if can power up the other working Nexus with that same connector unplugged. If the other one powers up then that's a pretty strong indication you've got additional damage beyond just the torn off connector.

Phone COMPLETLY died while i was using it.

As you can see in thread, phone just dead. Dunno what happened. I bought it an year ago. I've tried to connect it to computer and it was visible as QHSUSB bulk but now i can't see it there. It doesn't react for turning on. I can't get into download mode, recovery mode. Very long time ago i flashed Android MM from xda and it was working good. It had ~50% of battery when died. I've tried to put off battery and then connect to pc but still nothing happen. It has broken screen (was working good) but i've done it in September 2016 so. I can connect it to Linux but i think it won't help too. Any fixes? I think they won't take It at warranty because of screen. Phone looks like dead for ages :<. @edit IT'S NOT DEAD! I've disconnected something from battery this longer one and when i click power i can hear "something" in the phone. And it gets heater so looks like processor is working. But it's still not visible in the device manager.
edit2
i know emmc pinouts.

While I was using the phone, with battery at 66%, the exact same thing happened to mine. I'm sick of it. Time for a new phone.
(Had the rooted V15c image on it, no broken screen, only the camera issue - should someone care)

Same problem here, what is happening . My phone was approximately 80-90% and it suddenly turned off and I can't turn it on ..

bump

Phone went black with warning
The same just happened to mine. It was fully charged and I was using it and then the screen went black. There are no lights when I plug it in, no vibration after pressing and holding the power button. Nothing
I've connected it to my pc and a driver installed, I think the same one as a post above (QHSUSB) but still the phone doesn't respond in any way.
It's the European H955 on official MM 6.0.1 no root or mods and is out of the one year warranty yet was in excellent condition. Does this mean the phone is for scrap and nothing can be done?

Hi, I found a solution to repair the phone in this state. I start by telling you a story, a long time ago I had an HP laptop. video card was detachment from motherboard, and to a stick again we used a method called reflowing. I thought that the phone has the same problem, however we have nothing to lose so I opened the phone I took out the motherboard and started to warm up each chip using a hot air blower. I mounted the phone back and now works like new. I apologize for my bad English I am from Romania.

Any one tried this method and succeeded may please inform on this forum

My phone crashed, would reload to lock screen then restart and finally would not start at all. Before this the rear camera stopped working.
I had reset, flashed a new Rom and replaced the Camera which didn't solve the issue.
After the phone died I tried reflowing though I had no heat gun so I just used the oven. 200c for 7 minutes after disassembly.
That was about 8 hours ago and I am typing on my phone.the Camera is also working.
I will post if it stops again. I did it as the phone was dead and I had nothing to lose.

I have the same problem, and I am interested in getting a heat gun for this purpose. What specific parts of the phone did you reflow/heat? (in terms of the chips, or the entire board.)
Thanks in advance.

Also be sure to take off the rubber part on the back. The purpose is to remelt the solder.l, so only board and nothing else.
To disassemble there are some videos on YouTube. Remove your sim card before taking off the backing
Remember this is a last resort, you could end up with a completely dead chip.

Thanks for the information. Is there a specific way you have to remove the shields, or do I use a soldering iron to get it off? (And if so, does it do any good to solder them back on?)

Did it 395 degrees Fahrenheit (201.66 Celsius) for 7 minutes, I preheated the oven. The camera and everything now works fine.

You shouldn't have to use a soldering iron to take anything off. At least not as far as I am aware of.
I should note that as of this morning my phone when blank and will no longer turn on. I will try reflowing at a higher temperature as some solder may need a higher heat but I am not optimistic that this is a permanent fix.

Hey everyone !
First try to connect it in emergency mode to the computer in order to flash with LG UP. If you cannot boot into emergency mode but the device appers on your computer ( and PC is unable to connext into GF2) maybe you could burn your motherboard.
I burn one 7 months ago with my device resting on my pocket so its a common problem for this device (as official support told me so its full covered by guarantee )
Hope you can solve soon !!!
