I had been somewhat unlucky and while charging my beloved FLO something went puf (literally). After that I don't have any USB connectivity. Charging my N7 works (very slowly), but no USB OTG or USB ADB. OK Fine and dandy if I wouldn't be total idiot and wipe system while trying to install new ROM before transferring ROM image to internal storage.
Now I have FLO paper clip able to go to TWRP but can't install nothing. As far I understand there's no way to enable wifi in TWRP.
Any ideas what would needed to be replaced to make my FLO work again so I can put some ROM on it and make it work again.
I'm not sure if USB daughter board would suffice and solve my problem. Any suggestions?

Either the USB port developed "dry joints" or the wide silver cable (LCM) needs to be re-seated on both connectors.
Disconnect the battery before fixing LCM cable. Here is advice on USB port repair.
Replacing the daughterboard PCB should be the last resort because it is unlikely that the touch function will work 100%. It would work if we had access to the touch calibration software - the problems are described here https://forum.xda-developers.com/ne...rivers-to-calibrate-touch-screen-usb-t3334898

I doubt re-seating would help or cleaning USB port, since it was something electrical happening with that *puf*. If my memory serves me right there was a smell of burnt electronics. I doubt that some shortage disconnected any cables.

Sounds like you need a new charging port and board. Easy to fit but difficult to get hold of one. Maybe purchase a broken Flo on eBay and extract the charging port board

Even tho charging works? The only problem is data part of USB connection. USB OTG will not work neither will it connect to a PC for file transfer/adb. But if connected to PC or plug device charges. I believe it will not charge past 80 or 90%.

Charging over USB works fine no matter the cable or the connection but it no longer will show up in Windows on any PC as a device. I tried flashing roms, changing cables, and doing the usb fix with Terminal listed in the sticky but it doesnt connect or will it know it's connected to a PC.
Can the port be broken so data no longer works but charging does?

I have tried 3 which is why I wonder if my phone is broken, but it charges fine.
On all PCs the charge light comes on the phone with no problems but with all of them none of them detect a USB device being plugged in.,
Even in recovery if I do a USB-MS mount nothing happens.
Can the usb port break so that it charges with no issue but wont connect to a PC?

I think the solution to your problem can be found in this fix
The USB port on my Evo 4G will charge but won't show up as as a device on my laptop. If I hold the USB cable at an angle, though, it does show up. I think mine is busted, maybe that's the case for yours.

Do you think the cable is busted or the phone? I have tried multiple cables on multiple PCs and nothing happens.
So then it is possible for the phone to be unable to connect but still charge fine?

Have you tried mounting when in Recovery?
It really sounds like your cable is weird. The power lanes are on the edges for USB, meaning that the port on the phone is probably physically fine. The cable, however, is vulnerable to damage on any one of the four wires.
If nothing works, then perhaps something internal is busted. What do you need to transfer from your computer? Perhaps you can do it by connecting to your computer through WiFi for mounting the SD card and adb?
Its your USB port on you phone, theres 2 pins or smoething broken inside your phone thats causing the problem. I had the same problem on my Evo were it wouldnt connect as a storage device and would go into car dock mode. I took it to sprint and showed them the problem and they replaced my phone. As long as you dont have any physical damage such as the screen being cracked you should be fine and they should replace it free of cost.
Make sure that your cable is not one of those charge only, car charger type cables. Typical car charging cables don't transfer data.

Yeah, that's pretty much it. If I wiggle it just the right way the computer will see something but it will go away as fast as it shows up. Doubt Sprint will do anything as the phone is a few years old, I dropped the protection plan, and it's rooted to heck.
I'll just keep it running until this fall and upgrade when the new Nexus line comes out.
Hopefully.
I have a kf1 with a jacked up Usb port. I can get it to charge with some wiggling but it doesn't show up in device manager. Is there anyway to root without Pc or fix the port?

That's happened to me several times, and I can speak from experience that it is your charger failing. The USB plug on the stock chargers are poorly made, don't fit well, and will eventually fail because of it.
The new black USB cables that Amazon is selling for the second generation devices, fit very well, and will charge your device without fail.

If you're dealing with an actual hardware defect like the one you've described, it will only get worse, especially if you have to finagle it to get it to work properly. You cannot root the KF without a computer, so you should probably look into getting it repaired or replaced.
Hi all!
My computers USB port was broken and it let all the electric through (don't know how to write these thing in english)
I connect my phone to the USB and don't know that.. then my phone only charge through computers usb and pc doesn't even try to recognize it.
Then i connected my microsd cardreader to same usb and i heard "puff" and smelld burning electric.
Phone does not smell like burned or anything. Working just fine.. it only doesn't work with data transfer.
So.. is it possible to fix by myself? like changing the usb dock https://ae01.alicdn.com/kf/HTB1xvUoMVXXXXaoaXXXq6xXFXXXf/5PCS-For-Xiaomi-Mi-Max-Hexa-Core-6-44-Smartphone-USB-Charging-Port-Dock-Connector-Transfer.jpg
Or is my phone bricked forever and i cant use it through usb cable?
i hope that you all understand my problem, it's hard to write these thing different language
Anyone?
Replacing the usb dock piece will probably fix your problem and isnt very hard to replace and isnt very expensive from aliexpress. I cant post links but if you go to youtube and search "mi max disassembly" it will show you how to take apart the phone and get to the piece. i have taken myn apart before and it isnt very hard at all. Hope this helps
Sorry, it's not clear to me. Is there a problem with the USB port on your phone? Or only a problem with the USB port on your computer?
You may want to try a different USB cable. Sometimes the microUSB adapters can get worn out.
Problem is on the phone. Phone only charge from usb. Settings are ok.
Same usb port broke my Canon also. It has warranty and its fixed now. It was same way broken than my phone.
Computers usb is fixed now.
Hi,
I'm desperate, I tried everything on my ZF2!!! Since I upgraded to Android 6 theUSb interface has stopped to work. I mean: I'm not able to connect the phone to my PC: no ADB, no Asus Flash tool, no xFSTK nothing.
So I decided to downgrade it to Android 5 (also unlocked the bootloader) but didn't help. Of course I tried different cables/PC/OSs and I replaced the USB pcb on the bottom of the phone.
Can anyone address me to a solution? I'm just looking for a way to flash TWRP in order to install a custom ROM.
Thank you in advance
Does it connect in TWRP?

No, I never flashed the TWRP, I'm still with the stock recovery. I just unlocked the bootloader by the ASUS app.

have you inspected the connector to the motherboard side. also remove flex cable from the bottom side PCB and Motherboard side. inspect it if there is some broken connection point on flex cable.

try replacing flex and bottom pcb with other mobile if you have one

This is what I did. I upgraded (manually) to 6.0.1 few month ago and and when I discovered the USB problem, I used UL-Z00A-WW-52.20.40.196-user.zip to downgrade to 5.0 and unlock the bootloader by the app (now I have the white screen).
I also have a dead USB port problem. Mine bricked twice and was recovered using xfSTK and stock ww-2.20.40.198 firmware. Now I need to re-root, but the USB port can only charge (sometimes it wouldn't even charge) and no adb or anything else. My computer simply didn't see the phone. It's all stock, bootloader not yet unlocked. What else can I try before I order a replacement USB port board off ebay?

have you tried to disconnect sim flex connector ? lot of times bottom pcb is not the culprit. its either bad flex connector or faulty flex. also try to swap USB cable lot of times that is faulty too.

I reseated the sim flex at both ends and the cable is back. I'm rooted again. Thank you!
Try pushing down on the flex cable just below the sim2 slot.
It seems that these cables have got some weak connection at the bends which break very easily when replacing the usb board.
Also do you have any vibration issues?

Good morning!

Thanks to everyone
due to my own stupidity, i had unlocked and installed twrp with a lot of effort, as the usb is decidedly iffy
i managed to use a file manager to import the requisite lineage rom and gapps, and then in my infinite wisdom stored them somewhere volatile - one mistake i won't make again
and so when i cleaned the device prior to a "new" install, i inadvertently lost the zip files, and now the computer refuses to recognise the device
no amount of forcing the right usb driver onit works, because i presume the computer does not know it's a flo
so, is there any way i can get it connected and push the roms to storage ?
my skills at the command line are limited, but i can follow scripts
this is sad, as i was soooooooo close to completing the install, after which the usb would have become redundant (i have a wireless charger and can wifi file across with a working system)
is this thus my very first brick ?
or can i trick the usb connection into working with the computer, or somehow wirelessly transfer to such a basic installation, or rig an otg connection (i have no cables that would seem to join micro-usb to any female plug to use a memory stick or sd card in adaptor)
thanks for any suggestions :fingers-crossed:
Get an image file from Google https://developers.google.com/android/images
Try going into TWRP and go into sideloading (can't remember exact menu - only used it once to get out of a similar problem), then try to connect USB lead to PC.
Run flash-all.bat on PC and that should at least get a system on the device.
Maybe...
thanks for the suggestion, but the sideload could place the lineage.zip instead if the computer would accept a usb connection - that's the problem: sideload can't work because the usb device is not recognised
my best bet would appear to be load the zip via otg - the twrp interface appears to allow that
i'll report back here if that works (once i procure a usb otg connector)
I was in a similar position once and couldn't get a normal USB ADB connection with PC until I tried TWRP sideloading which kicked in the PC connection.
Did you try it?
OTG was the next thing I was going to suggest

As the USB port is broken there is no hope that an OTG adapter would work because it can not function without the data connections, exactly like PC-USB. Have a look at the port's soldering, it may need some re-work. If the port's connectors are damaged then a replacement is very cheap.
:good:

i sprung the back and was going to attempt to reflow the solder in case it had a dodgy connection - but i noted that the actual usb connector looked like it had been stretched, and took to it with my favourite pliers and performed some creative metalwork by squeezing it
lo and behold! the otg connection worked, at least for long enough to transfer the custom rom
thereafter when i reassembled the case, the otg connection failed but now the usb link seems to be happy enough even though that makes no great sense seeing it is the same connector port, and the otg works on my other android devices
still, gotta take what you can get, and i am now the proud owner of a nexus 7 "flo" with lineage doing nicely
thanks for all assistances

Ahh this explains why my N7 - used daily - has never developed any USB port problems! I thought that this USB port's construction was rather 'weak' so preemptively I applied a simple reinforcement, have a look at the attachments.
It was 4 years ago....
