Dear all,
I try to gain access to my Sony Xperia ZX2 compact.
I don't have the schema nor the previous google accounts that were attached to this device.
USB debugging is not enabled and the photso is locked (message when we try to install a new ROM from the fastboot mode).
So I try to access the JTAG interface from the phone.
I unmounted everything and tried to find the JTAG interface on the motherboard.
Of course nothing is written on th emotherboard so I tried to find the JTAG interface with a multimeter.
But I'm a little bit stopped here as I'm not sure how I can validate the values returned by the multimeter (I get a few possible solutions).
Once I find it, I will then have to "build" an adapter to get access through USB interface
Is there anyone that ever found the JTAG interface on a ZX2 compact?
Or is there anyone that can help me to find it and to go through the next steps?
Thanks,

Bit of a weird one.. Hermes doesn't support host mode as far as I know.. but I turned it on this morning and got the error message:
"Unidentified USB device. Enter the name of the device driver for this device."
Which from what I can find on google is USB host mode not knowing what driver to load for a connected device (Nothing was connected at this point)
I'm using Sleuth's current ROM and haven't ever seen this before.. just wondering if anyone has seen it and if it really was trying to start host mode? Or had it just gone mad? (I cancelled the message and all is fine now)
(I'm guessing the host mode hardware/software is all missing and so it would never work.. but i'm interested all the same especially if it is software only that is needed)
Unidentified USB Device
I have the same problem. Can't figure why and no result on search. Can anyone advise?
I have flashed my i607 with the i600 new ROM and now I can't flash the phone back.
The phone works because I haven't flashed this part, however had flashed the PDA and have no camera anymore, no vibrator, but at least a working O/S.
I have tried the following:
a ) Purchased the D820 cable. I can see the phone connected using Tera Term in COM1, however is not seen by the WCE downloader as this is looking at USB ports.
b ) I have tried installing the modem drivers time and again, and tried to connect ActiveSync in COM1 according to these instructions:
(1) Use a Samsung D820 cable with Serial Port and plug into your i60x
(2) Connect the cable to your PC's serial port (probably COM1)
(3) Install the Samsung Blackjack Modem Driver
(4) Uncheck the "Allow USB connections" in Active Sync option and select COM1 in "Allow connections in one of the followings"
(5) Let Active Sync to search for the i60x and wait for "Connected"
(6) Run the i600 firmware update program as usual.
NO results. ActiveSync does not connect.
c ) Tried Corona Downloader ver 3.2 for Samsung SGH-D500, it connects to the phone, but vendor ID sent is 0x44 and the phone responds 0x52, aborting further exchanges. I also tried OneNAND downloaders ver 1.4, 1.7 and 1.8 with similar results. I know these flashers may not work on my phone, however gave me an idea some exchange was taking place...
d ) I tried to load the bootloader eboot.nbo in root of the SD card, however i don't know if there should be a key combination to boot from SD card or if there is one other trick nor what name the file should have. Any ideas here?
e ) I have made dumps prior this mishap of all 4 raw partitions in the phone. Is it there a way to write a partition using a utility that I can place in the SD card? Is it there available a SD flasher that may run from the phone?
f ) Is it there a way to modify the WCE downloader to work on COM1 instead of USB?
g ) Is it there a way to modify the device driver to accept the phone as it is now? Apparently the phone device driver messages windows with a device malfunction and Device not recognized. Is it there any way to bypass this?
h ) I even tried to use a Serial-USB bridge and WCE downloader. No results either.
If you have any ideas, please respond to this thread. Any input will be deeply appreciated. Thank-you in advance.
Hi,
Is your Samsung device a derivative of a HTC product or have you posted in the wrong place?
WB
I don't think so
I don't think the Samsung is a derivative of the HTC, nor I want to enter a discussion of territorialism, now with all due respect I though this forum was a place to openly exchange knowledge on xda devices, and yes, as this topic has to do with hacking, and yes, because I have seen postings on Samsung i60x and i71x devices, is why I have posted here. Do you have any insight about the subject matter?
Thank-you
Hi.
I have Coolech 1FA-09D based board with Hisilicon Hi3716C chip on it. It's android based media player. Full system flash was performed on the device, but firmware flashed was wrong, so device is now useless.
It stops at boot screen (not android, but bootloader). On device I have 2 available usb ports, but I asume those are host ports, not to be connected to PC. On PCB I have 4 pin connector, but don't know what kind of connector that is. At the moment I have no documentation for the box.
Company that I got box from will provide me original firmware, but how I'm going to flash it? Any ideas? Fastboot as far as I know works only with usb connected devices. ADB can't connect to device trough lan cause no adb server is running on the other side (box get's its own IP address and does some other initialisation which includes usb ports and then freezes).
The 4 pin connector is a serial console, but be carefull, its 3,3V logic and not RS232! So you need a level converter or usb ttl converter cable like for a old cellphone or something. Then within uboot you could load the firmware from tftp or upload it with xmodem.
Could you please send me the firmware? I would be very interested in it . (Or just upload it somewhere like filesonic)
Thanks.

Thanx for your answer.
About the firmware, sorry, I can not send it to you and there are two reasons for that:
I don't have the firmware yet. When I get it, I'm not allowed to distribute it. You can find kernel source code of similar device (A.C.Ryan android based box) on their web page. Their device is also based on Hi3716c.
Hi,
Yes, I am using a acryan box clone and wanted to check out the features of the Coolech firmware on my box. That was the reason I asked about it. But okay, if you can't share it, its fine.
Hi, I hope someone can help me. I have the following error at boot and the tablet stops at this error: Boot Verified Failed...
Short story is that I have spent the last two weeks trying to correct this error. No matter what I do I can not get past the first step in anything recommended on this site which is to connect to a PC. For some reason I can not get the tablet to connect at all, more specifically I can not get the PC to acknowledge it is connected. I am using the micro usb slot on the tablet. I have tried all the acer drivers, 4 operating systems including ubuntu, win xp, win 7 and win 8 and all of this on two different computers to be sure that it wasn't the PC being the problem.
Could someone help me how to figure out what I am doing wrong or what I am not doing right? Or does this tablet error mean that the tablet will never talk to a PC. I have tried APX mode as well as various combinations as per recommendations on this forum with the rocker, power and reset.
Hopefully someone can help me.
Thanks a billion in advance.
So it doesn't look like anyone can help me with this problem but perhaps someone can help me with getting a schematic of the inside of the tablet so I can perhaps fix the micro usb port myself unless someone knows another reason why I can't get it to work. I really need some help, hopefully someone can help me.

Strange problem and one I've not heard of before.
First try a different usb cable, they are not created equal these things!
Ensure usb debug. is enabled in Settings.
Connect yr tab to yr pc. Open device manager and check the android usb device driver is installed. If it has you should be good to go.
If it doesn't. ..head to the cpuid guide in my sig. There's a whole section near the end which deals with driver issues and how to set up and test adb etc.
I do have a schematic somewhere, got it
off here so try a search.
Oh, one other thing. ..u didn't mention adb drivers. U can download them from the cpuid guide.
Good luck

my phone os is android8.1.0, it can be used adb before, but I fogot what I do with it. Now the phone can be used normal, calling and connect Internet is OK.
But when I connected usb cable it was no response, please someone can help me?
Is the driver installed on the PC? I used disk management normally to find new drives>scan for new devices.
Cable may be bad.
This might help, read down a bit on the initial post. It talks about adb and how to connect to the device.

the driver has installed before, and other phone was work well but nexsus 6p is not working
Can you see the drive in Disk Management?
Look at Event Viewer for error messages after trying to connect. Try a different port and cable.
Try rolling back the driver and/or search for one in hardware management.
Try on another PC.
Could be a failed C port on the phone, inspect contacts and carefully clean if needed with a soft toothbrush. A blower bulb is helpful too.
Check usb configuration in Developer options on the Android.
