[MDA, XDA, 1010 Software Upgrading] rpc:
8) To all XDA_Developers and Enthusiast Hi !!!

Let me share you the update I made with my QTEK 1010

After Reading all forums and making to many updates..

My previous version is 4.00.05 and RSU 4.21 from Jeff's kitchen, I downloaded the file T Mobile 4.00.10 (nbf) which comes from Aurora, it doesnt have an update for radio because i don't want to screw up my radio stack, the bandwith that i am using is 900/1800, anyway.. after successfully update my OS i check out my XDA to see the difference, use it for a while, and then decided to downgrade it back to Jeff's 4.00.05, but the problem when i try to update it using Activesync Advance User(PROGRAM A) the adaprom doesnt work anymore. So i try to use the bootloader way, i download my nb1 file to SD Card, or shall we call it i made a backUp of my current system(Bootloader and OS)(How clever of me), i tried to look for a nb1 file in my pc, and i didn't find one i have only nk.nbf and my internet connection is so bad right now, I can not download. So i use nbf instead (How stupid of me!). I rename the nbf file that i have to nb1 and write it using xdarit to my SD Card 128m, after finishing the write it give me a message "write successfull 65536 blocks" and then upload the OS to my XDA, i saw in the screen that message "Checksum ok!" so i assumed that it is fine, so i make a cold boot(pressing in the small hole), then..... whenever i make a cold boot it doesnt go to the OS it show only Wallaby Bootloader 5.15, so i thought that my OS is destroyed, so i copy again my nb1 file (which i backup) to the SD card and uploaded it again to the XDA, walla!! the OS is working!! and i can see the **T** Mobile on the screen R4.21 and 4.00.10, the OS is working fine.. but the problem, the Mobile(Radio stack) is not working anymore, i can not hear any sound if somebody is calling me, and i can not make a call, I thought maybe it is only RSU problem so I update my RSU with same version 4.21 and still my mobile is not working, so i downloaded again the same T Mobile 4.00.10(which I back Up) to SD card and upload it again to my XDA,... i found a message on the screen "Checksum not correct!!" after finishing the Upload. I make a cold boot, Now my XDA is dead :( i can see only a BLACK screen with G32s54, R4.21.00, and 4.00.10 in the screen with black background and red text, and it doesnt continue loading the OS.

My conclusion is I think..correct me if i am wrong... I overwrite my bootloader, because the blocks should be 65024 not 65536 which i copied in my SD card and also it writes a different size of Checksum in HTC$WALLABY11, that's why whenever I make a nb1 writing it gives me a diffent kind of errors on the XDA. 4 times i try to download the nb1 file to SD card and upload it again to my XDA, it gives me different kind of errors. because the location of OS which is writen on the Wallaby header format changes everytime i upload a new OS. ( the Size should be the same).

The solution I make is write both bootloader and OS to SD card(which i back up before) using Xdarit and upload it to my XDA... Now finally my XDA is working fine, I can call, and i can revceived call, i check everything even the OS(WM2003). my XDA comes a live again..but I am stuck with T Mobile 4.00.10, I hope my internet will work fine so i can download Jeff's receipt 4.00.05(nb1 files), so i can go back to 4.00.05. :wink:

The lesson....

1. be very carefull of what your writing in the SD Card that you will use for uploading to your XDA( you don't want to use your unit as a paper weight). make sure it is not corrupted.

2. always make a backup of your bootloader and OS (pressing power button while resetting and selecting BOOT+CE TO SD from the screen) put it in the safe place. Like if you are having a Bolt(a Safe) :?

3. Read the first message on this forum ( Flashing ROM's are very very dangerous) take it seriously. :roll:

4. be glad that we have a forum like this who helps all kind of people (techie/non-techie,programmer/nonprogrammer) to guide us to explore and experiment with our XDA unit.

XDA-Developers.......... May the force be with you.. Always :twisted:
