Rescriere Bootloader Hermes200

Recommended Posts

Am un HTC Hermes 200 mort in urma unui flash incorect (nu mai porneste nici in bootloader), am inteles ca se poate baga fortat bootloaderul prin interfata JTAG.

Am gasit cum se face acest Test Point prin interfata JTAG -> http://forum.xda-developers.com/showthread.php?t=391047

 

O singura problema am, nu stiu sa fac interfata pt JTAG, am gasit schema dar vreau sa o faca un profesionist sa nu gresesc ceva.

Daca poate sa ma ajute cineva, contra cost desigur, rog sa lase un reply.

 

Multumesc Anticipat.

Daca erati atent, vedeati ca scrie in primul post facut de mine.

Toti pasii sunt explicatii in linkul de pe xda forum ! :wretre

 

1. Disassemble your device (link to the Hermes Service-Manual is in the wiki).2. Locate the JTAG pins on PCB (download/extract htc_hermes_jtag.zip -> look at the picture)3. Use a very small soldering iron and attach some wires to the testpoints (only experienced users should do this!)4. Use one of the wiggler clones (LPT-adaptor) to built up a connection to the JTAG pins using LPT port of your host pc.Please have a look in the software documentation for the schematics (JtagFlash_Prog_Code.zip -> Source files and doc included).Whatever your adaptor would look like, follow the pin assignment, that is used in the schematic (e.g. LPT pin 2 -> TCK, LPT pin 3 -> TDI, LPT pin 4 -> TMS, LPT pin 11 -> TDO)5. Partly assemble your device and insert fully charged battery. Check all connections and press and hold power button on hermes (min 2sec.).Though the device won't start if your bootloader is bricked, this step is necessary to activate internal power supply.To check if power is O.K. measure the VCC pad (VCC ~ 3.15V).6. Use the modifed samsung software on your host (download/extract MSP_HERM.zip -> MSP_HERM.exe is a command line tool)Please make sure that the processor is recognized. If not check all connections again!7. Grab IPLSPL210_OLIPRO.zip, extract it and put the file the directory where flashing software is located.8. Use flashing software (MSP_HERM.exe) and try to reflash your NAND.type: MSP_HERM.exe /f:IPLSPL210_OLIPRO.bintype: 1 to choose the flash typeNAND flash type on hermes is k9f1g08 and should be recognizedtype: 0 K9f1g08 ProgramStart page and block must be set to 09. Be patient and cross fingers while flash is programmed.Alternatively you may grab some coffee or beer and relax!10. Enjoy the rebirth of your device.
