Hey all,
So after successfully going S-off on my own phone, I was unable to do so on a friends. The problem now it seems is my linux box does not see the phone as /dev/ttyusb0 when plugged in.
lsusb shows as:
Code:
Bus 001 Device 016: ID 05c6:9008 Qualcomm, Inc.
But I am unable to complete the LazyPanda Unbricker because it does not see my phone. ADB devices does not show it either.
I have run modprobe qcserial many many times, as well as plug and unplug, hold power for 30 seconds etc etc to no avail but no /dev/ttyusb0.
So what are my options here? Any advice would be greatly appreciated. Really frustrated.
Upon further investigation the Qualcomm USB modem is registering
Code:
[11087.431154] usbcore: registered new interface driver usbserial_generic
[11087.431160] usbserial: USB Serial Driver core
[11087.434594] USB Serial support registered for Qualcomm USB modem
[11087.434839] usbcore: registered new interface driver qcserial
For the archives:
I was able to get the unbricker to work finally by using a different distro. Apparently older versions of Ubuntu server don't work. You must unplug any usb to serial converters as well because they will be bound to /dev/ttyUSB0.
run
Code:
sudo modprobe -r qcserial
Plug your phone in then run
Code:
modprobe qcserial
type dmesg and look to see if your phone is bound to /dev/ttyUSB0
if it is, you are good to go.
Hope this helps anyone who had the same issue as I did.

Hi!
I got OTA update to ICS today, and everything went smooth. The phone is working fine. I connect it to iMac, run adb devices, and there is see my device. I'm also using vmware fusion with Ubuntu, where I develop Android apps. Ubuntu does not see this device. Previously, it worked fine. Yes, the device is connected and configured to be available to guest machine.
dmesg and lsusb output follows:

Does anybody know what is going on?
Thanks!

Am I the only one having this problem? Any other Ubuntu users with Galaxy S2 and ICS update?

This disables USB debugging. I did it anyway, but it still does not show up. Unfortunately.
I solved this by editing Ubuntu.vmx file. I added the following lines (I believe the last line makes a difference):
Code:
usb.quirks.device0 = "0x4e8:0x681d skip-reset" # Mass Storage
usb.quirks.device1 = "0x4e8:0x68a9 skip-reset" # Media
usb.quirks.device2 = "0x4e8:0x6877 skip-reset" # Kies
usb.quirks.device3 = "0x4e8:0x6866 skip-reset" # SGS2 ICS

I have tried Windows before Ubuntu, I was able to identify as APX in device manager but I could not understand and get any results, and decide to move to Ubuntu.
I appreciate if I can get straight answer that I can’t seem to find:
Since it’s visible as APX in ubuntu and Windows what are % chances to be recoverable?
I’m newbie and I have tried to learn as much as I can…but after a week of frustration I’m very down on energy, and lost …in commands that don’t seem to work as specified on forum.
I appreciate any help and direction on where should I start.
Thanks

Sorry to say, but as you don't have the nvflash back up files APX mode is of no use to you, try buying a second hand motherboard of eBay and replacing it

Hello, I m after some help.
I ve got an Allwinner A20 tv box, it worked fine for a few months then one day, after being on (but idle) for a few hours, I noticed the screen was blank but the light on the front was blue (indicating it was on, red is standby). It would not respond to the remote control or to anything, so I unplugged it and since then it will not boot and the screen is blank, the red light will light up but that is it. I ve eliminated the remote controller not working, but I cant boot the device.
So I ve tried connecting via ADB (with Ubuntu) but I cant get the device to show up after typing "adb devices".
I can get the vendor id and device id and I ve added it and the manufacturer to udev/modeswitch devices, but when I type "sudo usb_modeswitch -v 0x1f3a -p 0xefe8 -S -R -W"
I get the following error:

Any help would really be appreciated.

I am trying to resurrect my old Samsung Galaxy i5500. A couple of years ago I tried installing some custom rom but failed and bricked the phone. The boot process halts at the Samsung logo (the very first logo to appear.)
Putting the phone into recovery mode (using the volume down button + center button + power button) works, at least i presume that it works - the logo with the android shoveling dirt and the word "Downloading..." beneath it appears - but neither adb nor fastboot can see the device.
My troubleshooting so far:

What do I need to do to be able to connect to the phone using adb and fastboot?
Thanks!
The "recovery mode" that you mentioned, is actually download mode and it's used to flash packages with Odin.
Use it to flash a custom recovery and then use that to flash a custom ROM. Format /system and /data as ext4 before flashing the ROM.

I'm having problems with a Chinese tablet that I believe to be a Mediatek TAB910 with a MTK6592 processor.
It started by having problems with the SIM slots which I put down to a faulty SIM card. I obtained another from the telco but that didn't solve the problem. I concluded that the problem was with the SIM slots or with the software so I did a factory reset.
That appears to have gone well EXCEPT that I cannot get past the "Enter Privacy Protection password" screen (PPP). Let me say at this stage that I have never used PINs on my SIM cards; in fact, if I put a SIM card in which has a PIN then the screen asks for and accepts the SIM PIN but still presents the PPP screen.
I have tried to connect to the tablet by USB in order to try SP FLASH, but that tool doesn't see the tablet at all.
I then tried sudo dmesg|grep usb to see if there was any recognition of the USB and got the following results:
[237820.461318] usb 1-2: new high-speed USB device number 22 using xhci_hcd

It appears that the tablet is identifying itself, but immediately disconnecting again, hence no response from SP FLASH.
I can get the tablet to drop into two factory setting levels, one with English language instructions, the other with Chinese language instructions. Both of these appear to work as expected when I run through the menu items including, in the Chinese menu, "Eliminate eMMC".
I have also modified the udev files, but seemingly to no avail.
~$ cat /etc/udev/rules.d/80-persistent-usb.rules
SUBSYSTEM==”usb”, ACTION==”add”, ATTR{idVendor}==”0e8d”, ATTR{idProduct}==”2000“

Thanks for that but I have already been down that rabbit hole without success. My big problem is that the USB comes up but promptly disconnects again
Usually MTk preloader comport will disconnect if correct bootloader is not detected. So check you've got MTK6592 supported sp flashtool version and original firmware loaded. For privacy protection removal you need to format whole flash except bootloader and flash origin firmware then need to repair imei.
For some models you need to press and hold VOL+ or VOL- or both to get in to flash mode.
