TUTORIAL: 100% Working Solution for Unlocking HTC P3400i with SNo. HT8xx

[Krazy_About_Technology]

Hey Guys,

Its been about a month since i, ankit from mumbai and many others were working on finding a way for unlocking the newer models of HTC P3400 (manufactured after March 2008) as well as the new P3400i which originally comes with Windows Mobile 6.

On XDA forums, there are a lot of ROMS available with Windows Mobile 6.1 and other useful software integrated into ROM but all of these were for the old P3400i and it any of these were used with newer versions, the phone was bricked! Many people spoilt their phones this way.

Thanks to Orefklov, an XDA senior member, who developed an unbrick solution to return these dead phones to life. That same method has been used by us in this solution.

After using this solution, you will be able to upgrade to one of the available custom Windows Mobile 6.1 ROMS for the new gene. As of now, there is only one available called the WWE Fusion 9.0 ROM for New Gene by a respect XDA member, Lomlom.

This ROM is quiet good with minor bugs that are tolerable. It includes the HTC TouchFlo interface that came in HTC Viva. It also boosts the speed of this mobile due to the windows mobile 6.1 OS. SO its a worthy upgrade.

Please note that this operation is quiet dangerous if not done properly, so those with faint hearts, keep away and enjoy your device. I do not take any kind of resposibility for your phone or your physical well being, that may be harmed during this operation, for whatsoever reasons. However, me and many others have tested this on our new devices and all are currently in working condition, even better working than before.

All the credit for preparing this solution goes to XDA members including Lomlom, Orefklov, Ankit360 and others.

So here is how it goes...

Original contents from XDA forums....

This tutorial is only for New HTC P3400i With serial number HT8XXXX + Splash Screen Showing

ONBL 1.17.0000
SPL 1.17.0000
GSM 02.79.90
OS 1.17.0.0

Lets first unlock SPL (or u will get error @ 2% while update ROM With RUU )

Download gene_hspl


Copy program on your device (not memory card) and run it.

U see only green and red softkey blink and no display (don't worry )

Remove battry and reinsert (dont start it )

Download gene_unbricker.zip

1. Unpack all in some folder.
2. Press and HOLD "Camera" button and turn on device.
3. If you see 3-colored screen, release "Camera" button, else try again

Connect USB-cable to device.(In the left bottom corner of the screen to appear the text "USB")

(if u r using vista and vista asking for driver download here x32 x64

Run mtty1_42.exe program, and press button "USB".

7. In the opened window type the text:

set 32 1

Press Enter. (You must type this text by hand, not copy/paste)

8. After you will see answer from device in window.

9. Type in window that text but dont press enter yet:

ls boot.bin

Press and HOLD "Camera" button on device, and press Enter in mtty window.

10. After a while the device screen becomes white.
Wait 2-3 second, and release "Camera" button.

11. Close mtty program.

12. Run RomUpdateUtility.exe program and follow her instruction.

After this u will see

ONBL 1.17.0000
SPL 1.07. Oref
GSM 02.79.90
OS 1.17.0.0

Now download the ROM for p3400i GENE_wm6.1_19971wwe fusion9.0_new_gene_GENEs + ROMUpdateUtility.zip

Extract all files in same directory
Run RomUpdateUtility.exe program and follow her instruction.

if u want to switch back to orignal
here is is original release of HTC P3400i Asia India ROM.

Thats it, on next reboot, your new ROM will boot.

Addendum to the original method:
------------------------------------
In Vista, The Windows Mobile Device center installs new Mobile Device Syncronization Driver which doesnt allows updating of ROMS. If you try to tun MTTY with these drivers, the USB button will not be visible. To rectify this, download one of the 32bit or 64bit drivers from the links given in the original article and then follow these steps :-

1. Connect your phone to the USB cable.
2. Goto device manager and Under Mobile Devices section, right click SmartPhone USB Sync and click update driver.
3. Extract the driver from zip file to some folder.
4. In the update wizard, choose to manually choose the driver option and then click Have Disk when it shows a list of drivers. Browse to the directory where you unzipped the drivers and choose wceusbsh.inf. Click next next untill end.

Now remove and reconnect the cable, Windows Mobile Device center will detect the phone but wont be able to connect to it, leaving it free for the MTTY to use. Now you can continue the process. And dont forget to repeat these steps after flashing to make WMDC work again. The driver that you have to choose this time will have the same name , ie. SmartPhone USB Sync from Microsoft Corporation not only Microsoft. PLease remember that.

Please contact on this thread in case of any doubts before doing any experiments.

Enjoy Windows Mobile 6.1 and a faster mobile experience on P3400i.

Dear krazy

I have followed your steps by steps from XDA Developers which is basically the same as in here. I have reach the step 12 in your tutorial (Run RomUpdateUtility.exe program) and follow her instruction. However the error message appears:
"Error 300: Invalid Update Tool" and to use Never Update Update Utility.

Now I can't complete patching the SPL where it suppose to show SPL 1.07. Oref (for new gene). I know my phone is new gene as the version SPL 1.10.Olip in the earlier step, using gene_hspl does not work for my phone. I also noticed during the above RUU process, it ask to verify whether I want to update the ROM version from Image 1.17.720.1 (curent version in my PDA phone) to Image 1.00.000.0.

Question is whether the RRU program provided in the steps is the correct one for my phone as I suppose Image 1.00.000.0 is lower than 1.17.720.1 (just guessing from the version number) and that's why the message to use Never Update Utility appears. Anybody has the same problem and how to solve it? Tried a few times still cannot.

Is there anyway I can get back my phone if all fails as now I guess my phone is bricked with SPL 1.10.Olip on the screen with tri color.

This tutorial is applicable for my phone as I using HTC P3400i With serial number HT8XXXX + Splash Screen Showing

Quote:
ONBL 1.17.0000
SPL 1.17.0000
GSM 02.79.90
OS 1.17.0.0

Please someone help me out. It's really frustrating and I also post it in XDA forum for help.

tks, guys

Dear Krazy,

I have tried the STEPS BY STEPS in by you in xda developers forum which is basically same as what you mentioned here.

My proble is at step 12 where I run RomUpdateUtility.exe program and an error message:
"ERROR (300): Invalid update tool" and "This update utility cannot be used for your PDA phone. Please get never update utility".

I could not continue to patched my new gene. I know mine is new gene because after running gene_hspl, it bricked my phone and SPL 1.10.Olip appeared on screen and could not boot.

I noticed that before I hit the proceed button in the RRU program, there is a message asking to verify you want to update the ROM version: from Image Version: 1.17.720.1 to Image Version: 1.00.000.0.

Does it mean downgrading the Image version (Im guessing from the version number)? and that's why it doesn't work.
Is the RomUpdateUtility.exe program downloaded from your link not applicable for my phone and any proper one?

It should work as mentioned "This tutorial is only for New HTC P3400i With serial number HT8XXXX + Splash Screen Showing

Quote:
ONBL 1.17.0000
SPL 1.17.0000
GSM 02.79.90
OS 1.17.0.0

which is same as my phone.

Pls help any body as now stuck. BTW, is it possible to go back to original and save my phone.

tks
