Hi,
A maniac stole my phone and almost destroyed it. No more screen. Sadly I had some photos from my kids, birthday party and did not backup them :/
When I pluged the phone to a windows computer I see Pixel 7 on the device manager. I think I activated the developper mode though
I went to my local IT strore and he tried with an USB-C-HDMI adapter to see the screen on a computer screen, nothing appears.
Any hint ?
Thanks !
PS : Next move, buy a new pixel 7, plug a mouse and make the same movement to click the right digit and get in the phtone :/
Do u try to transfer data to new phone using USB cable?
One solution is to buy a replacement screen and connect it. You don't have to install it, just let it dangle.
What is your screen lock? If it's alphanumeric you can just use a keyboard.
You need to see what USB interfaces are active. MTP? ADB?
I wrote something to let a master Android login swipe a slave Android, see: https://forum.xda-developers.com/t/accessing-my-phone-with-a-dead-screen.4542763/post-88013171
I try to save some pictures in DCIM with an USB cable to my computer. Should I try with another phone ? ???
A replacement screen is about 250 €
How do I know which interface is active ?
In your solution the slave Android seems to have adb active.

No, the slave has to simply support OTG (which I'm sure the P7 does).
The master is acting like an absolute digitizer (and not a relative mouse) and also a keyboard.
If ADB is not on, this allows you to navigate to Settings and turn it on.
It's not simple or easy.
You'd need a rooted master of any random model.
You'll probably want a 3rd Android to test the master Android.
You'd need reference screenshots from some helpful P7 owner.
The video shows how, with a BT keyboard paired to the master Android.
There is the additional problem of there being no "hot key" for settings.
You'd have to remember where it was on your launcher.
OTOH, if you did have ADB already enabled all you have to do is unlock the P7.
Even if the screen is black the touch sensing may/may not be broken.
Use this utility https://ftdichip.com/utilities/#MicrosoftUSBView (or lsusb -v if you're on Linux).
Find your device in the left pane and copy/paste the text in the right.
(You can redact your serial number.)
It's really nice to help me like u do
Sadly it seems that my destroyed pixel 7 stoped to send data to my computer. I don't see anything on my w$ devices.
Do someone know if the motherboard "starts" with only the battery pluged-in ?
Which pin should be active to start up ?

Most devices that have a battery require a battery.
Batteries include a circuit board with the BMS (battery management system).
You're showing four contacts, quite a common setup.
One is for minus, one for plus, one usually for a 10k NTC thermistor to minus.
The fourth could be a simple resistor as identification of the battery pack or a one wire communication to some monitoring on the battery pack.
I'd need a better photo to say anything.
Is that your board? Did you remove it from the case?
You should probably just try to run things normally with the battery connected.
Ok, I often run Androids on a power supply but it requires care and a bit of know-how.
The advantage is that you can see if/how the device is booting.
I think this is a Moto E6 booting up, but I forget.
Found 0 ohm between contactor 1 and 4 when I push the power button in regard to those pins, so it should be it.
I still have 10 % hope, but the battery wont charge anymore...
NB : motherboard photo is from here
Did you check the battery for voltage?
With 99% certainty the two power pins are the outside two.
Is it possible that more than the screen was damaged?
It seems more likely that without an active screen you left it on until the battery died?
Heck, this thing is practically brand new.
Edit: Huh? I saw the video. The battery is connected on a mezzanine connector. I thought that first photo you posted was showing the battery connector.
It sucks that apparently the P7 only natively supports "GoogleCast" and not a Type C alt-mode video.
You can't get a slightly damaged (but working) screen from a repair place? You could just plug it in. Even just to borrow one.
The battery pion is so uncommon(mezzaine connector ?), I d'ont know where to make the measure :/
Yes it is possible, like I said it was a maniqac who destroyed my phone
The phone was 80 % full and left for a week end on the ground under water but fliped back (no water on the motherboard)
Yeah, my phone was 2 month old :/
NO video possible through usb C then ?
The screen costs approximatively 250 €. The maniac destroyed it ion purpose (connector screen riped of)
So the screen was actually removed?
I presume that you've tried to charge it?
Do you have one of those little USB adapters that measure voltage/current?
Can you see if it's trying to charge?
You won't be able to probe/measure anything on the mezzanine connector easily.
Since you're not sure of what is working, this is one of those cases where measuring current on the USB and the voltage/current on the battery are your first steps.
You might want to CAREFULLY remove the battery and take off the tape at the top of the battery until you can see the two tabs of the actual battery.
Be very careful not to short anything!
Do you have an adjustable bench power supply?
Hi,
Don't have those tester. Went to my it store, nothing's charging whern pluged in :/ I did remove the tape, but don't see any +/- tabs :/
could I try with the wireless charger ?
I could have such a bench in my highschool yes.

If you remove enough layers of tape (only on the TOP of the battery where the flex circuit goes in) you should see some shiny (somewhat) flexible tabs about 5mm wide.
Don't bend them too much and break them.

Has anyone else experienced this? My tilt will not charge if I use a cable that is a retractable charge/sync cable. The cables work because I use them with other devices and they charge fine. If I plug in my power cable, the tilt charges. If I use a portable battery charger, it charges. If I plug the tilt into the sync cable that came with it (not retractable and plugged into a usb port), it both charges and syncs. But it will not charge/sync if I use the sync/charge retractable cables. Like I said before, they both work because I use them for other devices.
I know this worked prior to cooking my own ROM. But now it does not. I'm not for sure if the two are related.
Any ideas?
Thanks,
Alan
Firstly, make sure that under Settings\System\Power\Advanced that the box labeled "When device is on, do not charge the battery when connected to PC" is NOT checked.
If That box is NOT checked, it should work.
Secondly, & most unfortunately, check to see if the USB port on your device is bent, curved slightly, or is slightly lower on the right side.
If it is, then you've got problems & may need to RMA your device
Mine use to do that. It would charge on the AC charger, but would not charge
on a car charger. I eventually had AT&T replace it under warranty.
Take a look at the two pictures below. The top one is what mine looked like
and the bottom one is the new one.

A RMA may not be required, but the truth is, it is even quite possible that the cable is not capable of providing enought power for the kaiser to charge from. From my own experiance of retractable cables I have seen that they were not able to power my USB DVD-RW. While another, single, normal cable was more than capable. Id just like to add that the DVD-RW was meant to be only powered by USB. So try a different normal cable first before RMA. This as well the above posters information should fix your problems. If this helps, your welcome in advanced.

Great Pic Post! I can't tell you how many people have argued with me stating "If the USB is damaged it won't charge at all, anywhere, no matter what".
I certainly know that if it's a curved USB or slightly lowered on the right side it can definitely cause a loss of only car & PC-USB charge because it happened to me. People still argue though saying that's immpossible.
As another poster suggested, try another cable or try your cable on another device.
Im personally using an insten retractable mini USB cable, and I have no problems syncing/charging with it.
Erg. I looked at the usb port and I indeed had a pin bent all the way down. I tried to straighten but of course it broke. I purchased through Amazon (with a two year contract) so I don't think it came with a warranty. So that sucks.
Can anyone recommend someone to repair (close to Houston, TX would be nice ? Or would it be easy to repair it myself by replacing the port?
Thanks!
Alan
I have an unusual problem which is even worse!! My kaiser ONLY charges from the USB port on my computer. I've tried 2 or 3 car chargers now and the orange light comes on for a bit then goes off. Mains charger won't work either - orange light stays on but the battery level continues to decrease. It's a real bummer if I go away anywhere as my phone just eventually runs out of charge!!
Yeah, same thing going on here... my wall charger works when plugged into the phone, but I have a desktop stand charger that stopped working a few days ago... and I have the same thing going on with my phone's port...
I have trouble getting Activesync to pick it up. Usually says "must install 4.5" on my phone. I can usually delete the partnership and reboot and it works, but my pin is slightly bent.
Sucks.
where can i find the pin to fix this myself. Just the part. I looked at mines today and its slightly bent maybe thats why its it doesn't charge. I will look online in google.com but let me know if anything.
You can get it from pocketpctechs.com. I asked them the same question and here is the answer I got:
"Yes, we can sell you the usb port as a part only for $25.00 + shipping. Place the order online for the full service repair, then email me your order number and I can change the order before it's processed."
But of course it requires the skill and tools of soldering.
For whatever reason, my pin became bent in my mini usb port on my phone. It bends down to the right and my phone will no longer charge from my car charger, but does charge from the ac adapter and does charge and sync via usb (thank goodness).
I called ATT for a replacement phone and they told me that this is not covered under warranty. Oh man was I steamed. I told the rep that this was not my fault but was due to faulty manufacturing. I explained that the pin must sustain hundreds if not thousands of events of being plugged and unplugged as the phone must be charged daily due to low battery life. I've only had the phone for 6 weeks. How could this be my fault? So, after much arguing, he agreed to set up the exchange, but warned me that HTC upon receiving the phone may have my account charged $450 stating that this was user induced and not covered under warranty.
Can you all believe this?
Same problem here
Same here, maybe worse
Since I had a Hermes I had problem with this connector. It is not very durable, especially if you use plugged head-sets with the phone in your pocket.
It happened that my kaiser stopped charging properly in the mais, I had to leave it with something forcing from below for it to work : )
Then one day the worst happened, the plastic bit around the pins came off, and it bent, and trying to fix it broke.
end of the story, since 13th of december I gave it back to tmobile and I'm waiting for it to be fixed. They also told me that tmobile could not consider that as been defect. That connector is the ****tiest thing ever!!! How can that be my fault???? Anyway, I have insurance that I can rely on as a last resort...
Going again to the shop to check if there is any news about my telephone.
Meanwhile they try to push a G1 to me, no way...
regards to all

To make the long story short, I took it to the shop, they send to repair, then it came back with a dodgy power button, as they had changed the WHOLE board!!! Send it back to repair, came still a bit weird button, the manager then gave me a new Kaiser, nice end
I have the HTC orginal car charger with Mini-USB connector. This car charger has and intelligent chip "IC" to prevent overheating when charge is 100%
Now, HD2 has a MICRO connector. My question is, if I use it with a mini-to-micro converter, will this "IC" feature continue working?
Talking about this:

And this:
wat, IC stands for integrated circuit.
Also, the charging mechanism to prevent overcharging or damage to batteries is on the device (phone) not the adapter.
Yes, the phone sends the "charged" signal, adapter receives it and stops charging and turns light indicator off.
What I am saying is that maybe the mini to micro converter will prevent that signal to be sent and hence continue charging/overheating?
Hello,i've the same thing and it works fine . All pins are connected in the adaptator .

no it's the phone that's drawing the current, not the adapter. Adapter is a "dumb" servant that serves current upon request.
the converter is just a wiring converter so again ther'es no intelligence involved.
Thank you!
I have 2 of that EXACT converters shown in the photo above... IT DOES NOT WORK!!!
For some reason, my phone will not charge when I use that adaptor... I also bought a Motorola one which works well
Thanks for the info!. Will get the Motorola converter as well...

Yup That one works fine and data works also... you can charge and sync with it
I have this
and cant sync with it, only charge, and i dont know why, because all pin are connect in two sides.
Guys,
I use Motorola P513 microUSB car charger. It works like a charm. After fully charged HD2 disconnects from it so there's no possibility to overheating. I really recommend it. An it looks fancy too

Dude... 1 have two of those and they both wont charge... not in car, via charger or anywhere else.... I was so pissed off as I got two of them... thank goodness for the Motorola one I ordered as a backup. That one even allows sync
THe one showing in the picture... when I plug it on the cable with the other end in the cigarette lighter adaptor, the cigaretter indicator light goes out on that end as if a circuit has been cut.... this happens even without anything plugged in and happens with both adaptors I bought... nothing charges also.... pissed me off!
from what i see that is also a surge protector. 8v to 3v, being a surge protector, it has a capacitor inside, and that will naturally block all data connection.

Could you provide a link to that motorola adaptor ?
I have searched Ebay and all the adaptors I found, specify they can only charge the phone, but not transfer data.
For some of them I also asked the sellers, and they said just the same - Charge ONLY.
Thanks

This is the one... as long as it looks like this... I am using it right now as I type this
Thanks for the reply.
I tried checking where and how they ship - and (as in many other cases) it seems they only shim within the US.
Since Im not in the US . . .
Is there any other one ?
About the comment that says - "as long as it looks like this" - well - I saw several of them, and as I mentioned in my previous post - they specify that they (the ones I saw) only charges the device, and when I asked the seller - they aslo claimed that it's only for charging, and does not transfer data.
(maybe they look the same on the outside, but the wiring is different ? - I wonder)
Be careful.
By the time you plug a mini USB plug into such an micro adapter, the potential leverage on the phone / micro socket will be quite considerable!
Why? What do you mean exactly?
The above one piece adaptor together with the charger's Mini USB plug is similarly rigid & I'm guessing about 2½ to 3 inches long - maybe 10 to 12 times the length of the actual micro socket! Some 10:1 leverage ratio. Maybe 3 times as much as without an adaptor.
I doubt that the design spec of a USB micro socket was ever designed to withstand the potential force that even mild accidental input leverage applied at a right angle would exert, on conversion to output leverage, on the phone's socket. For example, the leads tend to be 1 metre and are quite restricting. with the lead at right angles to the phone, 'testing' the cables length, the 'moment of force' (technical term) applied is likely to exceed the the design spec of the socket many fold.
I am suggesting there is a risk of separating the socket from the phone's chassis and/or its electrical connections to the printed circuit board within the phone.
At the vary least, due to the cables inherent stiffness, over a period of time the phones micro socket will get enlarged / bell shaped simply from small gentle leverage movements. IE. whilst USB connected, simply picking up the phone, messaging, or making a call. Eventually electrical / mechanical connections will gradually fail.
To reduce, but not eliminate this effect, I would suggest an adaptor cable as opposed to a one piece adaptor.
(Think I've waffled a bit here, but hope I've conveyed what I mean)
How's it going everyone, I just thought I'd share the mount that I've created for my Nook Color. Excuse the pics, I took them with my phone.
Before I get into it I there is a list of requirements that I had for my mount
1. It had to be as cheap as possible
2. It had to be one that I could easily remove my NC from to avoid weather damage, theft, etc
3. I couldn't make any modifications to the vehicle because I may eventually want to sell my car.
The things that I used for the mount are
1. some double sided tape ( $4.00)
2. cable hooks ( $2.50 )
With that being said here are some pictures of them
This is the set up for my mount. It's pretty cheap but it is SUPER effective.

If you notice, I've circled the top and the bottom to let you know how they work.
At the top you will notice two pieces on the left and the right, those are pieces of double sided tape, the reason that I put those there is because before in my first attempt, the NC would slide out and fall any time I turned my car, these add a decent amount of friction to reduce the sliding to when I make a sharp turn which is almost never.
The Velcro in the middle is from my first experiment, it doesn't do much anymore.
The bottom is 6 pieces of double sided tape, one side on the molding of the car and the other side is on the cable hooks that I used (pictured below)
Because of the shape of the molding I had to bend the hooks to make them conform. They are perfect because they are cheap enough and easy enough to bend that it wraps the NC with just enough grip so that it won't move.
Using this set up I have a mount that cost me less than 10 dollars and I love my carputer. Below are some pictures of the mount in action
Here's one during the day, you can't really see much
Here's one that I took of it at night, it's a little easier
For version 2 there are a few things that I'd like to add to take advantage of USB host mode but I have a few questions about it.
1. Does anyone know of a usb hub that I can use to be powered by and charge my NC at the same time? for example, I have a usb charger that I could use but when I use my hub I can't charge and use host mode at the same time, and I've enabled it in Nook Tweaks.
2. Does anyone know of a good enclosure that I can that has low enough requirements that the nook color can power it, or a 2.5 inch enclosure that can be powered by my cigarette lighter and then used with my NC?
Hey this is really cool. About what you were asking about how to power it, if you were going to use a hub you would probably need a high amp powered hub to be able to fast charge the Nook, otherwise it will only get a trickle charge. You would then need a cig adapter for the hub. I think a high power cig lighter usb adapter with two ports is more of what you are looking for. Keep up the good work and post your progress please.
very very nice idea..good for you
If you are fine with the regular trickle charge, you could just use a Y-Cable to add 5Volt from a external power source... that in combination with a normal USB to Micro-USB Cord + USB Genderswapper could give you the result you want...
However that way you will be limited to just one USB device, but seeing as you seem to aim for a external HDD this should be enough, right?
thanks for the suggestions, I'm looking for a good high powered usb charger for the cigarette lighter but I don't know of any that can fast charge a NC, do any of you guys have any ideas?
also the situation that I am facing with the external hd is that I can't find one that the nook can power on its own, If I could find an external powered hub to get it spinning I could use host mode that way, I just have no idea which one will do that
Edit: Can you guys see the pictures?

Nicely done. You gave me some ideas....
Completely stock, no mods.
Woke the phone up this morning to check twitter, email etc.
All of a sudden, it gives the beep sound, "mtp initialization" sound, media scanning messages, then loops around and does it again and again and again.
The only way to stop it was to connect it to the charger. Once disconnected, it starts doing it again. Took out the battery, SIM, SD card. Left it sit without those for 5 min. Plugged it back in and a few minutes later it started doing it again.
Any ideas???
It's run all day today without an issue. Battery down to 72%. Just connected
it up via USB to charge it a bit.
Only thing I did was to remove the mSD card and blow some air around the SD card & slot.
Bad SD card????
I think it might be a bad USB port
If I bang it slightly against a desk (rubber case), it stops doing it.
Sometimes if I pull the battery & put it back in, the battery logo thingy
comes up, it won't power up for a few seconds, then it will.
I got this via Amazon...it's a German version (DBT).
Anyone know a USA location for warranty service?
ah its probably pucsed up. The phantom usb connection syndrom. We should partition for a usb hole cover from Samsung
You got lint/dust in there m8 use compressed air or a fine brush to clean. check if that solves it. I had to clean mine several times. Never even saw the dust in there myself.
Sent from my GT-N7000 using Tapatalk 2
Dust? That's interesting....that port IS open to the elements.
That does sound like what it is doing. It thinks I'm connecting/disconnecting
the cable. How would dust "short out" a connection?
I'll give it a blast of canned air. Any suggestions (removing the battery) on hitting
it with a brush & alcohol?
green stuff inside port
I took my loop & was looking inside the port and found what appeared to be
some greenish corrosion inside the port?
Found a closeup photo of a microusb port and painted in the area where the
green contamination was. I took out the battery & used a stiff non metallic
brush to clean it out, then hit it with a can of compressed air.
So far, it's behaving...

That makes sense. Thanks for that link. The description from xphoneguy makes about as much sense as anything else. Especially his photos looked a lot like what I was seeing inside my usb port.
from the link you posted...
Why does this fix the problem? Well, I used to design cell phones, and I know a thing or two about the external connectors on phones. The phone has to have some way of detecting that something has been plugged into the connector. Micro USB connectors do not have a mechanical switch to detect the presence of a plug in the socket. If these connectors work the way USB OTG (On-The-Go) connectors work, there is a resistor in the cable between two of the pins. The phone attempts to pass a small amount of current through that resistor to detect the presence of the cable. When there is debris in the connector, like cotton fuzz from clothing, tiny bits of soap from washing, and tiny flakes of dead skin, and you add humidity from perspiration or rain, etc. you create little blobs of slightly conductive goo that can bridge the gap between the pins. That blob of goo looks just like a resistor to the electronics in the phone. So the phone thinks there's always something plugged into the connector. Why have some people been able to fix the problem with settings then? I suspect that they found settings that cause the phone to stop checking for a USB cable or to ignore the signal that tells the OS that something is plugged in.

So i accidently plugged in the usb the wrong way and the phone shut off. Have tried every button combination and holding down the powerbutton numerous times with no success. Led light doesn't light up and have tried leaving it in the charger for various hours and used different chargers. My next step was to disassemble the phone and hope a battery pull did the trick but that didn't work. However when I disconnect the black battery connector and plug in a usb the red led lights up for about 15 seconds and dissapears.
anyone know any possible solutions? I think my battery might have fried

Is there a way to jump the battery and hope that that works? I've jumped plenty of batteries on phones with removable batteries but I'm not sure if the Z has metal contacts for negative and positve
no one?
normally any device that has DC input (like usb) is secured with diodes so that even when a faulty charger is connected it doesn't fry. But that's my electrical knowledge speaking. Please reply when you found out what the problem is

Alright thx for the info but maybe you had another problem with you charger and the transformation from 12V to 5V was bad, that can't be controlled with only a diode. Or maybe your One X hadn't any security internally because the manufacturer wanted to save money on that component / no place anymore to put it in the phone.
Think I have something similar..... Connected to car charger, led didn't go red,pushed charger in moved wire in phone charger goes off, phone won't start tried all button combos.
Sad bit is I only just got phone 3 days ago:banghead::banghead::banghead::banghead::banghead:

Can anyone else comment on this? I recently did this and my Xperia Z will not turn on. Would replacing the battery work or is the damage related to the other internals?
Do you see any damage to the usb port?

No I don't see any damage to the USB port.
I did the same to my xperia Z1 (reverse biased it using usb and 5 volts wires) The battery however had charge so as soon as I connected the phone restarted and could not charge any more. Any solution please ????
Might be an old post but I had the same problem. I was fixing a cable (18V) and I wanted the range the cable in the corner. I was so lazy to use a screw driver or something else. So I used what I have in my hand: The jack cable, plugged into my phone. So I used the bare part of the cable (Don't ask me why, I don't know). I don't remember if my phone restarted, but he was fine. But not my jack connector. When I plug an earphone it says that my earphones are not recognized. So I change it (by my self) But still the same problem...
Seems like the problem comes from somewhere else.
do you found the fried parts of your phone or fixed it ?
i have same issue today i connected an experimental cable (v+ was placed into gnd pin and gnd to v+) to my lumia 625 and it flashes then shut off immediately now it show no sign of life not charging not turning on
anyone knows what parts have been fried ?
