Hi All,
I have a j710fn since 1 year, but lost my bill, so no warranty.
I applied the last rom by OTA. (7.0). All is working great. Very good phone, etc.
But, I can’t charge it, and the usb isn’t recognized when the phone is on.
When the phone is on:
- On wall charger: no charge.
- Connected with computer: no charge, no usb connection.
- Tried all USB options (AP/USB debug, charge, etc.) : no charge.
When the phone is off:
- When I plug the usb cable, it recognized the usb, and display the battery icon (with thunder) during 2 sec, and hide without display green charge.
Only the battery:
- The battery charge well with a lion charger.
- The android application “ampere” show battery is OK
- When charged, the battery powered my phone during few days.
In recovery mode:
- Wipe cache / data partition work well, but show /misc partition not found ( as some phone with Oreo).
In download mode:
- Odin work via usb.
- I download a Nougat rom and applied, but the problem is still here.
- I did again the OTA update to Oreo, same problem.
Hardware:
- The USB connector seem great.
- The mainboard is OK
- The battery connector is OK.
I think its’a problem with the rom that manage the charge. Many thinks are in /misc , as the usb controller informations, etc.
I tried all Samsung code to have more information, but all seems OK.
Do you have any solutions?

Firstly, I'm asking on behalf of a friend (saves him signing up) so I don't know all the details
Anyway... I recently gave him a Car USB charger (I had one lying around) which I tested out in my car using my HTC Desire HD....just to make sure it worked...& it did
(not sure but I THINK the cable I use is a standard USB to MicroUSB cable - not sure if it's a 'Data/Charging' or just 'charging' though)
However, when he tried to charge his Samsung phone (sorry don't know which one) it didn't
(BTW he is using his own cable he had lying around)
He tells me that he plugs in the cable between car USB charger & the phone - the screen brightens, but the charging indicator doesn't 'animate' & after a few second the screen then dulls back down into standby
Now I suspect that perhaps it's the cable - but he assures me that the cable he used worked on the PC. making me think it's a Data/charging cable
I know there's a difference between 'Charging only' cables and 'Data/Charging' cables, something about a couple of pins may not be connected but onto my question.....
[Q] IF he was using a 'Data/Charging' cable on the car charger
- would his phone assume it's being connected to a PC & automatically go into 'data connection mode' but then (because there's no data) the screen then 'dulls' back to standby mode ??
- If so, why won't the phone go into 'Charge only' mode if it doesn't see any data signal instead ??
BTW On my HTC - if it sees data connection I get a popup asking what mode I'd like (if unlocked) but it automatically goes into 'charge' mode if it's locked - I'm thinking his Samsung does the opposite when 'locked'... going into 'data mode' instead
Thanks in advance
***SOLVED****I have a Samsung Galaxy Skyrocket 2 SGH-I727, rooted on gb 2.3.5. It has been working flawlesly for months. All of a sudden, when I connected the device to power I was UNABLE to shut it down. I would slelect shut down and it would REBOOT itself instead of staying shut down and showing the BATTTERY ICON charging. Also suddenly I could not access the device as a mass storage from windows. Windows would say device not recognized. After researching for hours I came across one idea the did the trick. The problem was simple. The USB connector "tongue" inside the USB adapter in the phone apparently got bent somehow. This precented the USB cable connecting in from making contact with all the wires inside and THAT caused the 2 problems mentioned in the title. I took a very thin micro flat head screwdriver, GENTLY CAREFULLY put a little pressure on the USB tongue inside the phone's USB adapter and voila!...I could shut down the phone while connected to power, Windows again regognized the device. Who wold have thunk it?
For any of you who come across this, and I saw MANY MANY, not only for GS2 but for MANY andriod devices, and many failed "solutions", here is the answer!...
Have fun.
I think I have a similar problem.
Until two weeks phone was working perfectly fine. Then realized that the battery was getting drained in about 4-6 hours even when idle with no apps running, sometimes battery charge dropped like 15% in a moment, it didn’t indicate charging when connected to power though battery got charged and sometimes it indicated as charging when not connected to power. Phone could not be detected when connected to PC. Also, if I connected to PC after shutting it down, it automatically rebooted. This was weird.
Then when battery was fully dead and I connected to power, it tried to boot but immediately shutdown saying ‘low battery’ and again tried to boot… it was stuck in this loop.
I thought it might be android issue so flashed it with UCKK6 Kernel + Rooted System Package ((Thanks to creepyncrawly’s Download Repository)
But now, it still is not detected by the PC. It boots automatically when connected to PC after shutting down, but not when connected to wall power.
Cleaned the micro USB connecter, tried different cables and laptops.
Earlier Android: Version 2.3.6; Baseboard Version I777UCKK6; Kernel Version 2.6.35.7
After Flashing: Version 2.3.6; Baseboard Version I777UCKK6; Kernel Version 2.6.35.7
Pls I I tried to flash cm rom 12.1 on sgh 1727 skyrocket and it stuck on patching system image unconditionally n it stays there forever please what can I do?
Hello all,
To put it simple:
1. I buy oneplus power bank
2. Charge it with my original opo cable and charger
3. My oneplus didnt recognized as storage when connected to PC yet it is shown in charging state.
What I have tried:
1. enable disable usb debugging
2. select usb connection mode (mtp or charging or pnp) but it is not available
3. Recognized as storage using other cable data which havent been used to charged the power bank.
My question is : is it normal that your data cable will broken as soon as you use it as power bank's charging cable?
Nope, I think that's virtually impossible, have you tried using other cable to connect your phone with the PC?

Hi, I'm having this issue with my Galaxy S6 (SM-G920F):
One day fast charging stopped working, but standard charge was working perfectly, OTG was working, Odin too. MTP wasn't working!
One day I plugged my phone at the wall, and it didn't show that it's charging, after some reboots it started charging well (not fast charging). Sometimes I have to wait 0% for charge it again, but if I use a PC instead of the wall adapter it works (sometimes not, but I just need to reboot it)! So I'm able to charge the phone only from a PC if the battery is not at 0%.
I checked if OTG and Odin are still working... MTP is not working, I can't event hear the USB plug-in sound from Windows, if I go in Odin mode, Windows says: "unknown USB device" and it won't work, I tried to reinstall drivers, but nothing.
So right now:
- Charging from the wall won't work well.
- Charging from a PC works better.
- Fast charging won't work.
- OTG is working.
- Odin is not working anymore.
- MTP is not working, PC doesn't find the mobile, I also can't hear the USB plug-in sound from Windows.
I tried different things: re-calibrate the battery, restore the stock firmware via Smart Switch, flash some ROMs... But nothing.
I can't understand why some days ago Odin and wall charging (not fast) were working but MTP wasn't, now none of thease are working.
The only thing that works well is OTG.
Right now I'm using OdexLite ROM with stock kernel, but I tried different ROMs, Samsung's stock included.
Hello
I have a same problem .
Please help.
check if in the setting there is an option: start manager, try to turn on MTP application.
SM-G920I with same trouble, tried on fedora linux

I tried unsuccessfully to make my Fedora 24 and Fedora 25 detect the device, also tried on a MacOSX. It just charges, not only doesn't detect on download mode, as it doesn't even detect normally for file transfer etc.
Could it be an automatic update that killed MTP and fast charging? I've been searching the web for three days already searching for an alternative to flash/root or whatever to try to downgrade it and see if works with older version, but I couldn't. The device is 2yo, but is as new, I changed the battery and the connecting board on authorized service also with no good results. I hope I can make it work again! I appreciate any insight the community could have on this issue.
Cheers!
