JVC KW-NT3HDT half bricked - Windows Mobile Development and Hacking General

Today i flashed a modified NT500HDT software update for my JVC NT3hdt navi system, the unit gives a "update error" on a black screen, i cant access anything except using the source button on the lift side to browse for input signal...
Any input on how to access they system by using the sd card? i couldnt find anything online that could help, and not sure if jtag will help as i dont see any software to use with it...
the system is a "locked" wince
Thanks

more update
The unit gives a "Please insert the update SD card" error, and if i insert the card in it gives the "update failed", the unit still have working Bluetooth (phone and music) and radio but no screen to browse... and no navigation.
I did some reasearch and found that the CPU is the so called SoC "System-on-Chip", the whole OS is installed on a NAND chip, the chip is SH-NaviJ3 SH4A SH7777, and more rsearch revealed the location of the e-JTAG point.
BUT! it will be very helpful if i can connect my microSD card to the CPU and have it be the boot OS...
i really dont know what i have to do...

i want to downgrade from the wm2003 upgrade to the o2 rom

Ok, i konw there's already been several threads here about downgrading from the wm2003 rom (4.01.16ENG from the rom kitchen to be precise) but i can't seem to get this thing anywhere... as i said i upgraded the rom to the one specified above and found it far slower and unstable than the ppc2002; I wanted to flash the xda with the old rom but there's this strange communicate saying that the connection has been suddenly closed and the "programme a" stops. i tried to flash the old rom directly to the device using the xdatools but also with no success... it keeps on saying that it couln't communicate with the remote application... well then i thought about this bootloader fix (still unsure what bootloadre i have because i can't get the info anywhere) and it said that the memory on the device is write protected.... :/ well, and as for now i am waiting for a sd card to try that, but.... tell me, will the xdatools prepare the card if i insert it into the device? (i have no card reader for my pc) i am woried because each action i take (except normal device usage - activesync, copying and moving files, installing appz) that messes with the roms, shuts down the connection and i have to unplug the device from my pc and plug it again... please help me, i'm in dire need!
I am having a similar problem with the same rom version. I wish i never used that version! I did an update to wm2003 earlier and i could go back and forth with no problems, but this one is a real nasty one!!
the message i get when using osimagetool:
ERROR: GetConnectionType - An existing connection was forcibly closed by the rem
ote host.
error getting connectiontype
I am having the same problem ..
and when i power on/off the device it says (Unrecognized Card)
Enter the name of the device for this card. For information, see the card manufacturer's documentation.
and there is a place where i can write something (Unknown card in socket 1)

How about the phone? I cannot seem to turn it on. When the pin screen comes up it says i should turn on the phone, but i cant dothat anywhere..
Hi All,
The best option for ROM upgrade is always the SD method ... it's much easier and safer. XDAtools doesn't work with some ROMs because of the boot loader version not the ROM itself.
So what do you say guys? will i be able to downgrade it from the sd card? - and first of all, prepare the card having it inserted into the xda itself and using xdatools? i also wish i had never used it, the newest ppc2002 rom from o2 is just soo cool comparing to the wm2003 one i'm stuck with right now...

XDA 1 not working

Hi,
I was upgrading the software upgarde on my device. I successfully upgraded the Pocket PC software on the O2 XDA, but when I tried to upgrade the GSM radio/GPRS software of the O2 XDa, it gave some error and after this my device is not starting at all. The only mistake I did was that "I did not remove the SIM card before upgrading the GSM radio/GPRS software" The device does not start even after cold booting the same. When I start the device, the O2 screen comes and after a quite long time the main window does come but I cannot do anything. I tried to tap on contacts, time, tasks but nothing happens. I can see the windows logo wall paper but cannot do anything. Please help on how I can restore back my O2 as a cold reset also does not work. :?
Thanks and Regards
Jinesh

Hi,
I have tried all the available options but it still does not work. To restore the ROM how do I get access to the O2 cause niether serial nor USB is detecting it.
Please help.

SD card install guide
Ok here you go, its a little outdated but its what I still use:
Qman's how to use XDArit to write nk.nb1 or nk.nbf to your SD card aka the Bootloader Method!
1. Place XDArit and the nk.nb1 or nk.nbf file in the same folder and start XDArit.
2. Select your SD card (disk drive) from the drop down menu.
3. Select Write to SD
Notice that the Windows CE box is already checked so just click the browse button at the end of that window.
4. Select your (nk.nb1 or nk.nbf) image and then Open
Notice by default XDArit will open looking for a *.nb1 file but if you're going to use a .nbf file you'll have to manually change the "Files of Type" to *.nbf
Notice that nk.nbo / nk.nbo was automatically added as your boot-loader and its check box is unchecked so leave it that way and click OK. XDArit should start writing to the card.
When XDArit has finished writing the image put the SD-card into the XDA and hold the power button and soft reset. You'll be taken to the below screen:
SD DOWNLOAD
Card Type:
CE OS & BOOT
Press action to Download
Or
Press REC to Exit
Press action to download and it will start the download/restore from the SD card.
Follow the on screen instructions once its "Completed" which will consist of a "Soft Boot/Reset".

Hi Rudegar,
I tried the procedure given by you. I was able to write to the flash successfully. After writing to the flash it gave a message "Checksum OK, Please cold reboot to reset".
I did a cold reboot. After starting the O2, it showed the O2 logo screen and after quite a long time, it asked me wether I want to format the SD card or not. After that it took me to the default screen of XDA wher eit showed options like "Add today's date, Contacts, Schedule etc etc. but upon tapping any of the options the O2 behaves erratically. If I tap on today's date it takes me somewhere else. Inshort it does not work.
I again did a cold reboot and now the device is in its original position i.e not going after the O2 logo where it gets stuck up.
One thing I would like to mention is that all these activities have been done putting the O2 on the cardle only as the battery is totally discharged and the device turns on only after putting it on cradle. Even after the cold reboot it does not start unless I put it on the cradle whichis connected to the mains. Is it Ok with this or am I doing something wrong? The battery does not charge and hence I have to do it in this way.
Please suggest what wrong am I doing? Any suggestions from anyone will be welcome.

Hi,
Someone posted the original O2 ROM on this site and I downloaded the same after which I was partially succesful in flashing the ROM and reviving my dead O2 back to half life. :roll:
I burned the ROM on
to my SD Card and flashed the ROM on to my O2. After
successfully flashing the ROM I rebooted the device.
The device now starts Windows but it takes atleast 15
minutes to start. I get the today screen. WHen I cick
on start the start menu appears after a delay of 10
seconds and all applications run normal, however all
this happens only on the Cradle only.
When I go into the Battery Settings it shows "Battery
Status Unknown".
Also none of the phone functions work. The SIM card is
not recognized and in device information it does
dispaly the "IMEI number" and the "Protocl Version"
I am only able to use inbuilt phone applications.
Is there some problem with my battery cause it is not
charging even on the cradle.
Device Information does not show Radio Version, Protocl Version & IMEI number at all.
Can anyone please help me?
hello all,
it means that your radio stack are dead. Currently, We don't have any real method to fix this problem. When the radio stack is error, you can not upgrade it or do anything to make it work. We can only upgrade or downgrade the radio stack if it works. Also if you try to upgrade the radio stack, we realy need to flash the chip using a speceial tool or need the sd card which build in radio stack with we can only flash in bootloaading mode. Howerver, in some case, we can fix it but .... I think it is just lucky or the xda error when battery problem.... in this case, just disconnect the battery few minutes and connect it again by pressing the battery hole.
Regards,
Hoanghon
p.s. I have dead xda. I killed it when I upgraded the RADIO STACK. Therefore, if you are really need to upgrade the radio stack, I recommend use the official upgrade for secuirity. or just upgrade the rom only.
Note:
To eliminating the error, you need to upgrade the rom or the radio stack, you need to check if the rom fix the radio stack or the stack you are trying to upgrade it fix the rom or not.(ie, Tmobile Rom have to use it radio stack built for Tmobile pocket pc...... I know that in some case when we mix between the radio stack and OS it works but I don't think it work propertly. Anyhow the mixing bettween radio stack and OS is very dangerous if it doesn't suppport then you have to reflash the radio stack or rom(the OS is Okay but the keep upgrading the radio stack may cause the radio stack killed)
WE NEED SERIAL CABLE FOR PDA ANY HELP PLS!!!

Hi,
Thanks all for the replies.
Can anyone tell me how doI repair the radio stack?
Regards
Jinesh
no way without having special RSU rom update on SD card and run it from bootloader or dissembling the device and reprograming GSM rom on special rom/bios programing socket. (Here on forum is user Cgigate from Toronto CA who can do it but I cant contact him)

Wallaby Upgrade Blues

AS I sit here staring at my cute little Wallaby in it's cradle with a nice desktop, I long for 20/20 foresite. I can sync with my PC and and do anything I want as long as I don't want to make a phone call or take it off its cradle. I have been all over this web site and the web in general looking for a solution to the 1% GSM Failure Upgrade problem. I have tried every written idea and approach with no success. I am sharing my conclusions here with no particular hope of an answer.
It seems a low battery may cause the error in the first place. The first upgrade attempt got me to 16% and hang. I reset and got to 6%. Third time it was 1%. Once the battery is low the GSM processor shuts down. The GSM processor controls the battery charge. You can not upgrade the Radio Stack if the GSM processor is shutdown Even a new battery does not seem to reset the GSM as there is a software switch that seems to have been set. I have read some vague reference to a serial cable and hyperterminal used by TMobile techs to "reset" but no real details.
I am moving on with my life as Wallaby is dead.... I miss you, baby.
Have you tried this method?

Yes I saw this solution straight away and have tried it and several variations, but now that I review it I have a question. The wallaby's battery is completely dead so after the reset I must put it in the cradle for it to start up. It then produces the 1% again ala step 8. Now what am I supposed to do? Take it off the cradle and put it back on? That would cause AS to start. Are you suggesting the GSM upgrade will take place WITH the error message right on screen?. That would be super! I'll try it right now.

One other note. The developers ROM v1.1 will not active sync with my PC. Neither will v1.2. All the other STD roms I've tried will though. Any idea about that?
getting the image to run from the SD card
problem: radio stack upgrade failed (using the siemens upgrade) and now I get a GSM error and eventually a partial pocket pc desktop with no start menu or access to an explorer window.
OK, I used xda tools to copy the rom to the SD card (1GB card), inserted in the wallaby, held the power and soft reset the device, I get the boot loader v5.15 and then a GSM Error. From there, nothing. Any suggestions as to what I am doing wrong? Does the SD card need additional files or should it be formatted a certain way? Any help would be greatly appreciated.
Getting image to run from SD card
Charles,
If you search this site you will find many descriptions of how to load an image from the SD card. Sounds to me as if you did not get a valid rom image on the the card cause the boot loader should rcognize it and ask you if you want to copy it.
The bigger problem is the PDA rom does NOT fix the GSM rom, which is the one that is hosed.
I am now in week three after I killed my Wallaby and I am having severe withdrawal pains. I did not realaize how much I depended on it. Can anyone tell me where I can sent it to have the GSM/Radio stack fixed?
I have found how to flash radio via rs232 cable, but i need program monitor.exe (pc monitor ver 6.5.7) to do this. I can't find it. Does anyone have this program or know where i can download it?
Sorry for my english, I'm from Poland

Big problem

Hi
I am new here and i have problem
When i turn on my qtek9000, i recieve message Serial V.100.
If i connect USB cable it displays USB instead of Serial.
This happened when i tried to do radio upgrade (through usb hub, sim and sd were also in phone...).
I have 1gb SD card and also card reader mounted in laptop, so transfering files should not be problem.
Can someone help me with step-by-step procedure how to make my qtek work back. I used a lot of search but i am even more confused....
I just remember that when qtek worked Radio was something like 1.0.3.1 and also WWE was writen somewhere....
Probably i should put rom to sd with ntrw (which wersion of both),.......
please help....
might be a dumb question on my part - but have you tried a reset (initially a soft one but then a hard one of course, if nothing else works...) ???
I mean you will at least be able to revert back to the condition 'out of the package'...
Hope everything works out!
jup.both things NOT HELPED
looks like you're stuck in the bootloader mode....
try flashing the rom & the radio rom once again by connecting it to your laptop's usb...
i guess something screwed up while you were upgraging your radio rom...and you'd need to redo it!
Best,
San
can you please write me a procedure?
You might want to check the following thread. Everything is well described.
Cheers

I have solved problem with Radio upgrade. I am in much better mood now. 8)
Anyway i have 4 more questions.
1.) I am using bluetooth car-instalation Parrot CK3100. I am wondering if is possible to transfer any other sound except telephone conversations to that device. When i had Nokia 9500 i was able to hear every single click,tone,...i made on phone also on car-instalation. I also heard nokia ringtone in car instalation.With qtek i am getting generic car-instalation ringing tone instead of phone ringing. Otherwise primary intention (hands free talking) works fine. I would like to have that to be able to hear voices from various GPS software.
2.) Since QTEK9000 is PDA and phone in single unit I would like to have in car GPS application "always on top". Like previously mentioned i can easily manage my calls with car-instalation. Therefore i would like to run Phone section in background or GPS applications on top.I hope you will understand what i would like to say
3.) I also need in-car holder for qtek. Do you have any reccomendations?
4.)
My settings:
R: 1.04.02
G: 42.37.P8
D: 1.13.64.WWE
Is that ok or should i upgrade?
Stuck in bootloader mode
Hi guys,
Got stuck in bootloader mode following an upgrade attempt. Tried to reflash radio using the files from the pload folder only to get an error saying it's for the wrong device - tried this several times with the same result.
any ideas?
Is there a binary and a tool I can just do a straight upload?
thanks

Thanks DreamTheater
Thanks for your help - unfortunately I got the same message, ie this rom is not meant for this device etc...
Will see O2 can do anything (who's that laughing...???) - was going to buy a new xda mini anyway...!
1. REMOVE your SD/MMC card.
2. Soft/hard reset.
3. Run the upgarde again.
Step 1 above solved my problem.

[Q] HD2 LEO T8585 Clone - bootloader corrupted

I flash this phone with a wrong image, and now only a black screen appear.
Is impossible to make any key combination to get to the "download screen" ?
If I try to connect it via ActiveSync, fail, nor with K3firstAid. The only thing I recognize is the Huawei PC COM port. Appears only slightly illuminating the display, and nothing more.
I pray all the masters of this kind of cell phone to tell me that there is salvation, and if so, let me explain the process the "resurrection". (excuse the Google translation)
Thanks in advance
If it's not a true HTC phone then there is nothing that can be done for it here.
No, not a real HTC, a Chinese copy of it. I've seen on this forum that many people have problems with these phones, so I thought that there is someone who will help me.

My guess is that your fake HD2 uses a different bootloader than the real one. Most issues with the HD2 can be undone, so long as the bootloader is intact. Screw up the bootloader and your phone is done for. Also these ROMS are built for the HD2's hardware and drivers. Your phone may look like somewhat like an HD2, but the similarities stop there. Should have bought a real HD2.
Why you want to flash a fake HD2 with a genuine HD2 ROM in the first place is beyond me.......

I have not upgraded to the real HTC firmware, but with the wrong Chinese ROM, I accidentally made a flash from the model T5353, which does not comply, we reported the error at the 80% upgrade, is that I damaged the boot and communicate with the PC. Now I found the original ROM, all the tools we need to upgrade properly, but we need help to restore the PC communication, how to ActiveSync or any similar applications to recognize? Here are its hardware, you might be helpful:

· RAM: 256M, ROM: 256M, extend to 16GB max
· 4.3 inch touch screen, WVGA PX: 480 * 800

You technically don't have an HD2, as the hardware in your phone is COMPLETELY different.
So if you're looking for a definitive answer here, you probably won't get one, as there's very little relation between your phone and the real HD2.
Your pretty much screwed. Only option is to jtag, or move on.
Hello,
Recently I made a wrong flash ROM, and then I managed to turn on the mobile. I'm desperate and I hope you can help. After I returned from service, he could not do anything, I tried something at home. Basically, when I connect to the PC via USB, recognize it as a "new device", then install the IDT, then my PC recognizes it as "Huawei USB COM 1.0, COM port 7. The problem is that it constantly resets, and so at times he appears in the "Device Manager" and loses again. When he somehow managed to stabilize the relationship with the PC, you probably could I make a flash ROM via IDT. The IDT recognizes it, even after it lost 3 seconds. Obviously not a hardware problem.
Thank you so much in advance

Hi me too using china clone HD2 same as your.
So i have use the method before you can copy the .bin file into a micro sd card and reboot your HD2 with below step.
1) switch off the phone.
2) format the Micro SD card to fat 32.
3) copy and paste the rom .bin into the card.
4) input the card into the phone.
5) hold volume key -and+ and switch on your phone.
6) i will start to boot into the SD card.

Can you tell me what the exact name of the *. bin file? I know of that way, but I failed.

only hold green and red button(answer and disconnec button) and switch on the phone .the phone will restore factory setting without any bin or flash file .
Just buy another clone, OP. I dont think there's enough resource available (other than some xda china portal) to fix an HD2 knock off simply because they dont have the same hardware & software as official HTC ones.
