Can't repair boot i9070 - GSM-Forum

mariodepomi · 08-17-2017, 13:21

Hi
I'm trying to repair a dead samsung i9070.
I have already solder the wire to the RJ50 cable and connect it to the octoplus.
Then, I've pluged the USB cable into the PC. Windows recognize and install the phone like a u8500 Rom USB.

After that, I will start the procedure for fix the phone, but systematically the phone goes in something like a bootloop (turning on and off). I can hear the sound of windows (plug in--->plug off).

Welcome to Octoplus JTAG Box Software version 1.9.5.4

To make Repair Samsung GT-I9070 You need:
1. Connect it via Jtag cable to Box.
2. Connect to PC via USB cable (use both connection).
3. Install U8500 driver (if driver was not installed automatically) from folder "C:\Program Files\GSMServer\Medusa\Driver\U8500\" and try to connect the phone again.

Note: This phone can connect more longer, so You need to wait 30-50 seconds.

Hello.

Please check soldering of all JTAG wires, make each of them as short as possible (max. 3-5 CM length) and try to connect again.

To connect the device, perform the following steps:

1. Run Software.
2. Disconnect phone's battery.
3. Connect the phone to PC via USB cable directly to PC motherboard USB port, don't use USB hubs, this is important.
4. Insert the battery.
5. Install U8500 driver (if driver was not installed automatically) from folder "C:\Program Files\GSMServer\Medusa\Driver\U8500\" - as a result, "U8500 USB ROM" device should appear in PC Device Manager.
6. Disconnect phone's battery and USB cable.
7. Connect the device via JTAG cable to Box.
8. Connect to phone to PC via USB cable (use both connection).
9. Press "Connect" button in Software.
10. Connect phone's battery and wait 30-50 seconds till the device will be connected.
