Original: d900 g3 and g4 rom card brush description of any

Original: D900 G3 and G4 ROM card of any brush that (once the old models go through a special card G3 Brush tutorial, to be honest and I met the players failed to toss a successful, but also, and this method works differently written.)

Dopod Dopod D900 phone models produced in 2005, has been a rush 6 for senior citizens, many of the exposed components of aging, many players in the hands of the machines have not used the normal USB cable brush; outstanding in any one of this card brush ROM approach, G3 and G 4 were covered by two models.

At the outset, the card brush ROM is a last resort of last resort, the higher the risk coefficient is the D900 really able to assemble into a brick base Brush brush method. So be sure to charge the battery display machine accuracy, do not jump power, not strike three good products, but also sufficient power; well above two points, the possibility of dead brush that can be reduced to 50%; and can guarantee the machine never have not replaced the motherboard repair parts, that is, no string of machine components assembled for the original G3 machines or G 4 machine, can increase the success rate of 20%.

This method is only a temporary solution in the network has locked access to the D900 machine SUPPER CID test (brush mode, disable the PC synchronization software, USB connection, typing the command with the MTTY tas k 32, the information feedback is the ultimate 0 SUPPER CID, the final Feedback FF is not SUPPER CID); it is now difficult to find than SUPPER CID machine, no way measured, you have this condition and have "money as a cloud as" the spirit of the local Friends of the test, extra points if the thread thanks. (Unresolved network locks brush machine can not measure, the consequences may be serious, please hold their own.)

Introduction:

Highlights some of D900 were normal ROM of the nk.nbf G3 and G4 machines in the brush card.

Separate card brush Wireless radio_.nbf, or nk.nbf integration with ms_.nbf expansion card ROM can brush, but the expansion ROM ROM version of the corresponding different, making it more cumbersome are not discussed here.

BigRom (one that G3 models) and open the ROM Flash Disk memory cards can also be brush, but then changed temporarily brush only one way to another ROM, USB data cable connected to the computer, disable the USB connection on the computer synchronization software, with MTTY typing task 28 55aa Enter; to recover. USB port on your mobile phone in question can not wire brush Friends of the machine, think twice.

Preparation:

(Supplement, here are referred to under the practical operation of WINDOWS XP SP3, W7 tested)

1, for an SD card, TF, MMC cards can be, but it can not be SD2.0 standard SDHC cards; card capacity is best for the 128M (because the cards brush boot file is generated in the 128M TF card, write Test 128M MMC card, and real brush through, the other 256M to 1G of the card is not measured), its format, choose fat32.

2, write in the card reader, must not remove the SD card, otherwise may damage the SD card.

Brush the ordinary USB cable into a card brush ROM documentation files:

1, download HTC64.exe software (tutorial package there).

2, the normal ROM of nk.nbf decryption software with HTC64.exe split into nk.fat, set aside.

3, download HxD.exe software (tutorial pack containing); G3 models will G3.fat tutorial files within the package the software with HxD.exe open, select all and copy (the point right after the election and then right click on Select all select Copy ), alternate; then HxD.exe software to open the first "two" steps were generated nk.fat file in its top position, that is, where the offset is 0 paste (the cursor on the left Ctrl + V keys ), Save and exit. Instead G4 models within the package G4.fat tutorial will repeat the operation. Obtain the corresponding card that brush file nk.fat. (Remember not to because it contains Bootloader G3 and G4's boot file backwards!!!)

Add below:

In some of the first screen, without the traditional boot ROM (not including BigRom Flash Disk storage area and open the ROM) file nk.nbf split nk.fat, the size may be less than 63M, please HxD.ex e Tools copy in quotes "FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF" to the progressive replacement after offset 3EFFFF0 Department, and then paste at offset 0 corresponds to models of boot file. Since all this is to consider the brush card certainly will not go to the machine or damage the USB port is no longer clear the original MTTY ROM, the ROM brush off in history, the effect of brush left over file ROM, BUG.

How to brush file nk.fat card SD card write:

1, download ntrw.exe software (card brush package available).

2, ntrw.exe and written nk.fat files to the root directory of C, will prepare the SD card installed in front of the reader into the computer (remember to shut the card read-only protection.)

3, in the Dos command into the C: root directory, enter the ntrw write nk.fat H: Enter

(Nk.fat a brush in front of the card to produce their own ROM file name, H: is the SD card reader on the computer display corresponding to the letter, not necessarily H; Enter wait time after about five minutes, this process has indicator light will flash until the termination of the reader, DOS tool will go home directory.)

Recovery rom:

1, the front mirror of the SD card ROM is written into the D900, will be prompted to format, do remember that it is not reasonable or whether it directly points!!!

2, hold the power key + light key + poke living Reset Brush Brush into Bootloader mode (this step must use a hard bond method bootloader mode, can not be synchronized method or a software method EnterBL.exe bootloader mode. As has been used, please use MTTY empty again, or reset the firmware and then brush the official ROM for the following steps.)

3, wait a moment, there is an English prompt for whether to upgrade from the SD card, rom, press the power button; will have a percentage progress bar, because the only card brush nk.nbf part of the short time (about 10 minutes up and down), please be patient. Upon completion, will show black 100%; and complete card brush different, bright lights will not be long. At this time, press and hold both "-" button, poke living Reset, select the screen appears press "0", that is a hard start (this step must be, because the cross-system card, brush, such as the rise WM5 WM6. 5, and inefficient MTTY Clear the original ROM will be stuck in first screen, or enter the system after the BUG abundance).
