[Q] D802 not recognized with USB topic

Good evening,

I bought a second-hand LG G2 32go, and I realized that it had been rotted by the previous owner (while I had asked him if the telephone was "blank" of any root).
In brief, the telephone is never detected on any PC (tried on different 2, with various drivers) by USB (I just manage to see it in WiFi).

In normal mode (phone started), with the good parameters (Synchronization Media and Debugging USB): no LG tools detect it. I tried with several cables, several PC, several drivers.
I have access to the download mode (it is here I realized that it was rooted): still not detected by Flash Tool.
Hard Reset tried unsuccessfully.

The Android version of the phone is 4.4.2 stock, Pit version 3.4.0, Build KOT49l. D80220b and software version D80220b-EUR-XX.

I'm appealing to you because in my researches, I found cases of defective USB cables, bad configuration, or still " I found, that works !" but which do not share the solution :)
I had a S3 before, with whom I spent hours of research, but with G2, I am too fast submerged by links and too numerous solutions and I do not find myself there any more.

Then would you have an idea or a solution to help me ? I just want that phone to be detected by USB.

Thank you very much beforehand :o

sd card recognized, shows available storage, but no files topic

I just starting have a problem today that I hope someone can help me fix. I was transferring a file from my PC to my phone when I received a "File Cannot be Transferred" notice, and a hanging copy progress screen. So I clicked cancel, safely removed my phone, and unplugged. Now I have nothing showing on my SD, in Storage Settings it displays the card along with an accurate Storage remaining (4.5 GB out of 64 GB), but the file explorer displays no files. I've tried rebooting, unmounting/remounting my card, and still nothing. I went into recovery and can see files and deleted the partially transferred file, when I reboot, the SD card loads, Folder Mount runs and successfully mounts to my SD, I can even go to the file explorer and see files briefly, then within a minute or two.....poof everything disappears. Does anyone have any suggestions? Thanks in advance.

[Q] galaxy nexus stuck in bootloader, not recognized by pc topic

hi guys,
tragedy started like that: today i decided to give miui another shot. downloaded latest miui developer rom to sd card of my galaxy nexus, rebooted into recovery and flashed miui zip and tiny kernel afterwards. stupid me i forgot to wipe cache before installing the new rom. hit reboot in cwm, which kindly told me that the new rom could make recovery unusable. here i accidentally selected the obvious wrong choice, which said "dont fix problem" or sth like that. dont know if recovery is gone now... after reboot miui was trying to boot without success (mi logo shown until you turn the phone off). so i went to fastboot by pressing volume down (my volume up is broken!). fastboot acts pretty dead: cant scroll through options by pressing volume down, cant do "normal" start by pressing power, absolute no reaction of the phone. also the phone is not recognized when connecting to pc via usb (tried the samsung original driver). phone is recognized when miui is trying to boot, but i cant send any commands via fastboot.
im thankful for any advice that lets me install a new recovery/boot into recovery/make it boot again!

fastboot mode details:
product name - tuna
variant - maguro 16gb
bootloader version - primemd04
baseband version - i9250xxlj1
carrier info - none
serial number - irrelevant
signing - production
lock state - unlocked

[Q] USB OTG not recognized topic

Hi

I have a problem with my new S5.
For my S3 i created a USB OTG+Charge cable. For this cable type a 68k resistor is soldered between the sense and GND pins of the USB port.
this cable is not recognized by the S5. When I keep the resistor open the charger is recognized.
When I short the resistor the USB harddisk is recognized.
I tried a resistor E6 decade to test variuos values. When I use 100k the cable is recognized as "power sharing cable".

Is anybody here using a USB OTG + Charge cable?
Where is the cable detection definied? Can I change it?

Best regards,

SIM card not recognized. replacement part or repair? topic

Hello. Was in a hurry and attempted to pull out the Sim card (nano with an adapter) in my xt1064 and ended up removing it, but the phone no longer recognizes any SIM cards. I contacted a local repair and was told the SIM tray is soldered to main board. I did see this video which shows the dual-sim variant as removable (see at 4;45-5:00 min (http://youtu.be/l29IvoYolh8) SIM cards go inside (but not as before), but do pish in and eject OK. I read online re: trying to align pins in the tray, but didn't see a good tutorial. I did open the phone and the tray is not easily openable (see a spring on the side). So how would I go about trying to get this repaired? Looked at etradesuppky and just saw few major parts (screen, housing, battery), unlike a lot more small components avail for xt1032. Any ideas/suggestions? This had to happen right after I flashed an updated lollipop 5.0.1 with success after few weeks of waiting. Thanks for any input.

[Q] S Pen not recognized topic

I have searched through all of the forums and I have not found any solutions for this issue.
I bought a new Note 2 GT-N7100 from China
Tried it once everything worked perfect, running 4.1.2 CHN version
I tried to flash 4.3 but the Samsung cable was defective and lost connection
Testing the cable showed the compressed connector was too short and would not hold connection unless pressure was applied
I flashed CWM and was able to then flash 4.3 N7100XXUEM16
When I booted the S Pen was no longer recognized
Sensor to open S note when removed works but touch and hover do not
I have since upgraded to DN4 and Air Command works but still not recognized
I tried the original 4.1.2 N7100ZCALJ6 still does not work
I tried Restart S Pen app, as a shot in the dark but no success

GT-N7100 *#2663# shows:
Firmware version
Phone's TSP FW version: ME005370
Part's TSP FW vesrsion: ME005370
TSP Threshold: 65
Config TSP FW Version: N7100_ME_1026_M

Phone's Touch key FW version: 0x11
Pat's Touch key FW version: 0x11

FW Version of Wacom IC: 0000
FW Version in Kernal Image: 0268
Tuning version of WACOM IC: N7100_0912

SensorHub MCU FW Version: AT0112123106
SensorHub BIN FW Version: AT0112123106

It looks as if there is no Wacom IC FW flashed even thou I have flashed several ROMs. I updated the FW Version of Wacom IC: from this FW screen and it displayed successful but still displayed 0000. Any idea what the issue is or how to resolve it?
Any advise would be greatly appreciated.

[Q] I9300 won't boot, has no recovery mode and isn't getting recognized by Windows topic

Hi guys, I need some help with my Samsung Galaxy S3 GT-I9300.

A couple weeks ago my phone turned off by itself and never turned on completely again. If I turn it on, it stays on the very first boot screen forever (the white text saying Samsung Galaxy S3 GT-I9300, like this one (https://cdn-images.xda-developers.co...0.bootlogo.jpg).
I've removed the SIM card and the MicroSD card with no effects whatsoever, and I've also left the device turned on for hours but it always stays on the same screen.

I cannot enter recovery mode (it just shows the boot screen mentioned above) but I can enter download mode. At download mode, I get this info:
ODIN MODE
Product name: GT-I9300
Custom binary download: No
Current binary: Samsung Official
System Status: Oficial

As you can see, I have never flashed a custom rom (or rooted or even unlocked the bootloader). This is what intrigues me the most, since everybody I've seen with the same problem had trouble during or after a flash.
My last OS version was 4.3.1 and it was received OTA months ago.

In the past few months, my device rebooted out of nowhere, even when I was not using it. Occasionally, it had the stuck power button, which caused it to reboot on a loop, but I always solved it by nudging the power button a little. I don't know if these two previous problems might have caused the problem I'm facing now, but they're not showing up anymore.

Anyway, I've tried to flash the newest official rom (NK1 - ZTO) via Odin but I always get a NAND Write error.
I've tried changing USB ports, USB cable and computers; tried Odin 3.04, 3.07 and 3.09; tried Samsung USB drivers v1.5.45 and 1.5.49 but nothing of the above made any difference.

Today things started getting worse, though. In the past, Windows would always recognize the device on at least one specific USB port; Odin would also recognize the device and then I would get the NAND Write error. Now, Windows will not recognize the device no matter the cable, USB port or driver version. I only get a unknown device error and Odin won't recognize anything connected.

I tested all my setup with a working Galaxy S3 I9300 and it got recognized every single time, no matter the USB port, the cable or the computer.
Considering that another device is getting recognized by different computers, I suppose that the problem lies in my Galaxy S3.

So, can anyone offer me any kind of advice or point me in any direction on how I can try to fix my phone? Is my phone physically dying and no software solution will unbrick it?
