Ambitious : Try to hard debrick with an homemade JTAG LPT cable

Hello !
i'm from an engenering school in France,
i've 2 x8, one old, rooted, boot loader unlocked, nAa kernel and CM7, and the other hard bricked because of 11w34 -__-
So i want to connect my dead phone with a JTAG LPT cable homemade.
I've seen this thread here , the shematics of the X8, the reference manual of ARM1136 (msm7227 qualcomm)
so i know the JTAG pinout, i connect them, i connect the battery with other wires, and with the software H-jtag i tried to connect my phone hoping to enter in debug mod :
i can't configure the target as ARM1136 because there is a message error : "unable to load the driver"
i've read in the reference manual that ARM926 is still compatible, so i choose this one as target device and it seems to be working (i can see READY in the corner of the window )
but when i try to communicate with the phone, a new message say that it's impossible to enter in debug mod : check TDI clock and TAP config :
i put TDI clock at low level (i tried all levels )
and for the TAP configuration : i've read in the reference manual the register adress for bypass, i try something but i'm not sure to understant TAP num : is this the binairy adress of the bypass port ? there a screen, but not with my values

so is there someone who know how can i configurate the target access port connexion ?

Good luck with this dude...and report if you make it to work
sent from my ice cream

I would normally move the thread to Q&A but JTAG is an issue that has not been covered much, so it kind of fits here too.
Unfortunately I can't help you but it would be really helpful to inform us of your progress and hopefully make a guide eventually.
Thanks!

Have you tried MedusaBox? It repairs hardbricks via jtag
So try it, maybe it costs alittle bit but its worth it

tilakpil: Good Luck man! If you unbrick your X8 with homemade cables etc, YOU WILL BE A HERO!

Have you tried with UART connection?
Send me a PM,I would like to test it too,so maybe we can work it out.

Hello, i'd like to join this conversation because i have a dead galaxy mini in hand and it has got the same qualcomm msm7227 chipset. I'm also trying with an homemade wiggler and openocd.
I've managed to get the IDCODE and the debugging features (i think).
In this document you can see the chipset has got 2 ARM processors, one for apps and one for modem.
Following a thread about a HTC device with a similar MSM chipset, i toggled a script to use the ARM926EJ-S CPU with the right IDCODE.
I got the debug interface up and running fine, i'm thinking on what to do now

any updates?

Sorry but the phone i was trying to unbrick is dead now.

Can you explain please how you got the debug interface up and running ? and/or a link to the HTC device thread mentioned ?
Thank you.

The first step is to find the jtag header on your phone. Search on the net for some pictures, schematics or datasheet that may help you.
Once you found the JTAG header, you need a cable to be able to access it from a PC.
I used a wiggler cable, because it's the simplest and the cheapest. You can find many results and schematics on google if you type "wiggler cable".
Remember to use the proper voltage (3.3v), or you will fry your phone.
Once you have the cable ready and soldered, you can now move to your pc. at first i tryied openocd, but i am uncomfortable with command line debugging, so i looked for a GUI alternative.
On Windows, you can download H-JTAG, a software that will detect the cable and the CPU, and the NoICE Debugger for ARM

Good！

FTF firmware is different by every country?

Yes, a set of additional software. The essence of the firmware does not change.

Thanks a lot, i've unbranded my gorgeous Xperia Z

Flashtool - Can't enter Flashmode on Xperia Z
Hi, I'm having trouble when holding down the non-existent back button (I know it is a touch key and I try holding my finger in the position where the button is when the phone is turned on) and plugging in the USB cable...
Nothing happens Flashtool is giving me the pop-up windows that has the instructions to hold the back button and plug in the USB cable...
All works fine with my Arc S while holding the physical Back button and plugging in the USB cable...
Only way I get my PC and my laptop to recognize some kind of USB connection with the phone is while holding the Volume UP button and plugging in the USB cable - I get into FASTBOOT mode (Blue LED is on)
And if I hold Volume DOWN and connect the USB cable I also get connection but then I'm asked for QHSUSB_DLOAD device driver...
This could be the right combination for Flashmode (CAN'T BE SURE THOUGH) but the modded Flashtool for Xperia Z and the Driver folder (and the exe itself) don't provide the driver for the infamous QHSUSB_DLOAD (googled and found the QHSUSB_Drivers_(x64).rar Size(141.631 bytes))
After installation I get successful installation of COM port device called the Qualcomm HS-USB QDLoader 9008 (COM10)
But that also does not get me into Flashmode for successful FTF flash on my new Xperia Z device
Please help...
Waat is the key combination for Flashtool Flashmode and could someone link the correct driver if I got the key combination right but have the incorrect driver
Thanks in advance

On the Z you're supposed to hold the volume down button for flash mode.

Because now I know that i was doing corrcet steps but the problem still exists - Flashtool for Xperia Z is only giving me the window to enter Flashmode.
it might be an issue in 64-bit version of windows z ultimate i'm using but than again i tried it on my company laptop that uses Win 7 Enterprise but x64 as well ...
when i install Xperia Z drivers (provided in the c:\Flashtool\drivers folder) and start the phone with volume DOWN + USB cable plugged in my x64 Win 7 Ultimate or Enterpise i dont find the drivers needed in the provided drivers/flashtool-drivers.exe package...
then i find the drivers using Google skils and it doesnt work

First I found drivers with the correct VID&PID but those were for HTC HBOOT and my problem began...
... the correct ones are the GordonGate drivers v3.0.0 obtained from https://github.com/Androxyde/Flashtool/tree/master/drivers/GordonGate
good luck all :good:

I'm not sure anymore but i think GordonGate drivers are the correct ones but ones on Androxyde github do not contain the necessary VID_05C6&PID_9008
Could plz someone upload the driverz needed so that Flashtool can recognize my Xperia Z in flashmode
1. I do get the green light when holding the VOLUME DOWN + USB CABLE PLUG but...
2. my Win 7 x64 asks for drivers ---- Device Manager\QHSUSB_DLOAD with the info on Hardware ID tab VID_05C6&PID_9008
3. and no the drivers are not contained in the c:\Flashtool\drivers\Flashtool-drivers.exe - installed all of them, tried by clicking on every "Install anyway..." warning
4. Even installed the Flashtool-drivers.exe again with the Compatibility options of the EXE set to "Windows Vista" and "Run as an Administrator" (that way i don't get the warnings for "Install driver anyway..."
5. when googled i found several info that connected that VID_05C6&PID_9008 to "Qualcomm CDMA Technologies MSM" drivers - tried to download some Arc/Arc S GordonGate drivers from russian forum but the link is dead / unresponsive
this is the Copy/paste from russian forum
necessary VID and PID are contained in a file called Zeus.inf
and the preview of the Zeus.inf does contain necessary VID and PID

if not i can manage to use Flashtool on Win 7 x86 but i still dont have the drivers needed to try this...
only the preview on russian forum

After a few hours, I'll give you a driver.
Wait for some time.

NO problem mate, you've been very helpful so far so many thanks to your experience and a will to help
I also asked for help at the Androxyde thread for Flashtool for XZ 0.9.10.2beta4

there is my whole story and the problems I encounter with XZ
But I will check Your thread (every few hours) to see if You managed to obtain the driver
You can check out my whole story with XZ if interested and if you have time to read a bit more
Some day in the future i hope i will be able to help others as you have been helpful to me mate
I know it feels good to help and provide

I've tried so many driver but no change, it still no COM # in devices manager so in Miflash or any other Z1 Flashing Applications.
Need you help to solve this issue.

Method 1.
Turn off your device, keep pressing UP volume button and attach USB.
Method 2.
Turn off your device, attach USB cable and suddenly press POWER button after that (One time).
You will have Qualcomm port for 5 secs.

Tick "Use FIFO buffers", if it's already ticked. Leave it as it is.
Now locate "COM Port Number" and select any COM# (ex. COM3)
(Don't select 'in use' COM port)
Click "OK" and see if it works.

I'm facing same issue with my YU Yureka hardbricked phone also when I unplug it doesn't go, I need to restart my Pc to make it work again really need to solve this issue please help.

Is your phone in bootloop, if yes then let it completely die first. Then charge it for 5-10 mins( don't try to turn it on) and repeat the flashing process.
Make sure that ur flasing files are selected and com port dialogue box is already opened before connecting the phone on qfil. Then connect the usb cable holding the volume up button, as phone is detected by qfil imidiately press the ok button and then click on download. Com port detects only for 5 seconds.
Sorry for my bad english.

Hello everyone !
I have a Chinese Head Unit (Motherboard Marking: YT9260-ver0.2, Model no: 8227L_demo android 9.1, Android: YT9250_AHD_00006_V004_20190610_DSP, Kernel: 3.18.22, DDR 2GB FLASH 16GB, Mediatek MT6323LGA, Foresee FSEIAD9D EMMC 16G). Unfortunetly bad rom and preloader was written to the device and now it is completly brick. When i connect to USB my computer detects it (Mediatek USB VCOM), so maybe i can save it. Can anyone send me a preloader with scatter, rom and memory dump? Could someone please give me some ideas or advice? I also attach some pictures. Best wishes, thank you.

Remove the short when the process starts
If everything worked it should pass the RAM test. If not, don't proceed.
Disconnect the USB
Repeat steps 1 - 6, then continue to 12
Press Ctrl+Alt+V , then go to Window and select "write memory".
In file path select your backups (EMMC_BOOT1.bin, EMMC_BOOT2.bin, & EMMC_USER.bin), in begin address put 0x0, in region select the correct partition to match the backup. Hit Write memory. Repeat this step 3 times, once for each region (EMMC_BOOT1, EMMC_BOOT2, & EMMC_USER)
Short the two test points (see picture) without power and then plug in the usb cable (connected to usb1 port).
Remove the short when process starts.
Your backups are restored

I tried this method. My computer recognizes the device on COM3 port, in program the red progress 100% (Download DA 100%), then after 10 seconds the program prints Enable DRAM failed. I followed you instructions step by step, I shorted the two test points, but the program just prints Enable DRAM failed. Any idea ?

I have no memory dump. I got the device after they had uploaded faulty rom and preloader and they didn't make a backup. I know that if the preloader gets damaged, the usb connection will not be established, but in this case it will be up because my computer recognizes the device. There may be a problem with the preloader being defective and the Flash tool cannot write to the memory. Can we write through Rx Tx? It is possible ?

I got the same head unit with the same problem. Ill try this method and see what will happen

This is a bit old thread so I'm not too sure if it still useful, but if so I would recommend to use Arduino Uno which can easily communicate through UART.

How To Guide [Guide] Make Cisco-Linksys USB200M Ethernet Adapter work in Windows 10

Compact USB 2.0 10/100 Network Adapter Windows 10/11​
Foreword​I recently found this compact network adapter lying around somewhere. It's an older network adapter for sure (100mbp/s max), but why throw it away instead of using it? There is just one mayor catch: it won't work in Windows 10 natively. (Download link at the end of article)
How to make it work in Windows 10 (guide)​Since Linksys didn't update the driver to 64bit, it doesn't match to a modern OS like Windows 10 or 11 (latest driver for Windows Vista 32-bit, Windows 10 32-bit doesn't work as well). Windows doesn't run 32-bit drivers on 64-bit operating systems. So instead of downloading the device driver (Linksys USB200M), I searched the internet finding out, which Ethernet controller is used. It turns out that it is a AX88772A controller. On the manufacture site of the AX88772A there is a driver available to download. Once you downloaded (unzip first), head to the device manager. Find the unknown device, right-click and select update driver.

Select Browse my computer for drivers. Then choose Let me pick from a list of available drivers on my computer.
Search for Network adapters (tip: press "n" to jump to letter first n record). Open it. Now, instead of searching manufacturer (it wont work), simply choose Have Disk.
Now browse your downloaded driver folder and find a .inf file. Search for a entry called AX88772A. It might work with the non-A variant, but I selected this one.
Click next and accept the warning. The driver will be installed and you'll receive a success message.
After a optional reboot (I would recommend), the network adapter is ready to go.

I hope this helped!

I just found my old adapter, too. Which version are you using (mine is USB200M ver. 2.1)? I can't seem to get it to work. Windows is telling me that there are no compatible drivers for my device even after selecting the correct folder.

Compact USB 2.0 10/100 Network Adapter Windows 10/11​
Foreword​I recently found this compact network adapter lying around somewhere. It's an older network adapter for sure (100mbp/s max), but why throw it away instead of using it? There is just one mayor catch: it wont work in Windows 10 natively. (Download link at the end of article)

When I try to update the driver as instructed I get "Windows found drivers for your device but encountered an error while attempting to install them." followed by the name of the drive (same as your screenshot) and then, "This device cannot start. (Code 10)." Any suggestions or am I SOL?

Hi @LinusMandel
Have you selected the A variant of the driver (ASIX AX88772A)? That may have caused the error.
