Hello
I've got Lark Freeme 70.65, it's a cheap tablet based on Allwinner A13 procesor. It was allright till yesterday. I installed here CWM and Cyanogenmod 10.1 from there and it still was allright. But then suddenly, when I tried to replace camera drivers, everything collapsed, touchscreen is completely reversed in Y axis and it ain't got it's full range, so it was completely unaccesible. But it wasn't so bad, I did recovery of my stock rom from CWM mod, then once again installed cyanogenmod 10.1 and I did few experiments. It was nothing that would really hurt it, but I was so unlucky than in one moment every one way of access to the tablet failed. So right now I cannot use USB connection in any way, CWM when I try to recovery says about 'MD5 mismatch' (I haven't touched clockworkmod folder at all!) and I have touchscreen that is responding but is completely unusable.
Of course I tried different USB cable, different computer, different system and everything. lsusb can't see device at all, so do ADB. dmesg says this:
Code:
[91554.840089] usb 4-6: new high-speed USB device number 10 using ehci-pci
[91554.984872] usb 4-6: New USB device found, idVendor=18d1, idProduct=0003
[91554.984881] usb 4-6: New USB device strings: Mfr=2, Product=3, SerialNumber=4

[91554.986928] scsi8 : usb-storage 4-6:1.0
[91555.561110] usb 4-6: USB disconnect, device number 10
so it connects disconnects immediately after plugging the usb cable.
It would be great if I only could restore touchscreen or usb connection. I thought that replacing the rom would help, but CWM can restore them only from zips, and I have only imgs and I haven't found any way to do this.
I'm starting to accept my sytuation, this device was very cheap (170 PLN, it should be about $60), but it would be a great experience and happines for me to repair it. If anyone have got his own lark freeme 70.65 backup from CWM or any other Allwinner A13 and could upload this for me, I could try it out from any SD card (sadly I lost my own backup). Any other propositions also in common.

Hello
Last week I became my Star x26i. Its quite a very good phone, but because of WiFi and Battery issues i tried to update it to a newer version, like in this tutorial :
http://forum.xda-developers.com/showthread.php?t=1680338
So I used a program, calles SPmultiPortFlashDownloadProject
Everything went fine, but after the program erased the emmc Windows tried to install a new driver and failed. The program stopped and now the phone cant boot anymore (understandable with an formatted eemc...) The Pc detects the phone anyway, first as an unknown device and after installing a new chipset driver as "MediaTek DA USB VCOM Port (COM6)" If I try to reflash with the same program it gives me following issue like on this picture: http://imageshack.us/f/856/erroroly.png/ (Error: No Bootrom USB Port was found! COM6 is not a Bootrom (preloader) USB Port. Auto polling Number0.
Are there any Chances to rescue this device or is it totally bricked? Thanks in advance...
Hey guys,
So this has happened out of nowhere. Like the title says I can't sync my phone to my PC. When I plug the USB cable in it keeps trying to find the driver for the "MTP USB Device" and always fails.
I have installed the Samsung Drivers and have rebooted the computer and phone.
Is it possible I don't have USB mass storage turned on? I did a search but couldn't find where that feature is.
I'm running:
SuperNexus 2.0 Build 1
Thanks for the help!
flashed new rom with sad consequesces. Unable to get tab out of booting recovery kernal image. unable to reconnect to tablet as it show usb not recognized. have updated usb files with naked usb zip and also new fv flash files. still not getting anywhere. I have tried to flash recovery at apx but not working. Is there any hope or have I created a true brick/
Is your PC recognizing the gTab in APX mode (Power and Vol [-])? Does nvflash complete? Post screenshots.
usb not recognized

usb not recognized, tablet goes into apx but the computer does not recognize it. I have tried several different driver combinations and it still cant' see it. I think that I somehow screwed up the driver in the tablet. but can't even get it to connect to the computer. I tried a linux connection and it didn't recognize it either. I was using a live cd and tried to get the startup to locate a driver, no such luck. Is there a way I can completly format the tablet??? I can't get it past the boot loader error. thanks for your input up to now. hope someone has answers for me. I may have created a very nice parts machine.

You can't screw-up the APX-mode USB driver on the gTablet--it's built into the system firmware --ie. it's hard-coded. A HW error is a more likely culprit (if, indeed, the PC doesn't see the tablet in APX mode) . Disassemble the gTab and carefully inspect the USB port and surroundings for stray bits of metal, or solder, or cut traces, etc.

Since you can use Linux, do this:
1. Boot into Linux.
2. Put the tablet into APX mode (the screen will turn off).
3. Plug the cable from the tablet into the PC.
4. Run these command (only the stuff in bold) and post their output (or a screenshot):

Hello,
My phone is turned off and when I connect it with my laptop (same with my PC) it keeps getting disconnected and reconnected. My phone is ZTE Blade Q Maxi.
First, I thought that the problem was my USB cable or USB slot, but in the end, they're okay. The drivers I have installed on my laptop are following: Android ADB interface, DA USB VCOM Port, Gadget Serial (there's probably more, but they're seperated in categories). I noticed when I connect my phone, 1 driver appears - Preloader USB VCom port, about 2 seconds becauses instantly it gets disconnected.
Currently, my phone is bricked, but I've had this issue before.
Any help would be highly appreciated.
Thanks in advance!
