A si downgradal WM5 na verzijo 1.00.00.H? Mene je tudi full zafrkavalo, da sem svojega hx2410 spravil na WM6, ampak očitno nisem uporabljal pravega rom-a, sprobal sem jih pa kar ene par. Delal sem pa tako kot ti, preko white bootloaderja, ampak nisem imel težav s prepoznavo usbja. Ko sem downgradal na 1.00.00.H sem naredil format p.s., potem pa še enkrat pognal isti inštalacijski program in preimenoval novo datoteko z WM6 z imenom stare.
tole piše na xda developers forumu:
As of 12/23/07 there are 3 confirmed working roms for hx2*** series ipaqs. So far the pdaviet version(s), the newest in particular, is more stable, less activesync issues, preinstalled software ie: psshutxp and much more. (could use more feedback from others on this)
Please Note: (READ THE PLEASE NOTES! THEY ARE IMPORTANT)
Devices ending with .L (hx211x & hx241x) must be downgraded to .H before beginning wm6 upgrade process. Download both the 1.00.00.L and 1.00.00.H installers from the hp website. Use the .L installer to flash your device with the .H nbf (use the steps below, but substitute the .H nbf where the steps ask for the wm6) Continue to use the .L installer/flasher to perform your updates.. (the .h installer wont work for your device) So your sequence of upgrades will be: 1.00.00.L -> 1.00.00.H -> WM6
Please Note:
If you brick your pda DONT MESSAGE ME, try running a p.s. before you panic. Then if that doesn't work, put your device back into white boot loader mode and run the rom update utility that came WITH YOUR DEVICE. if you don't have it, download it, run it, and if needed perform a p.s. format on your device at the end. This will fix it. Trust me.
As promised: Here are the steps
-take out any cf/sd cards you might have installed. grab your cradle AND ac power cord (no AC cord = no flashing for you)
-put device into normal boot loader mode and downgrade to 1.0h w/files from hp website.
-format the p.s. (fyi everyone misses you have to HOLD DOWN the keys for p.s. format for like 4 or 5 seconds and THEN it will activate) After p.s. format wm5 will start.
(!! Start below this line if you are performing a wm6-4pda to wm6-pdaviet upgrade or vise versa !!)
-put device into WHITE boot loader mode and again run the 1.0h rom setup. When you arrive at the screen that asks "update" or "cancel",
1. rename the wm5.xxx.nbf to wm5.xxx.nbf.old
2. rename the new wm6.xx.nbf from the 4pda.rar/pdaviet file to whatever your wm5-wm5.xxxx.nbf was called (before you added the .old to it)
-NOW hit update. You shouldn't get any errors.
-After updated, wm6 wont start properly until you again format the p.s. (remember to hold down those keys to start) once this is done
-you should be golden.. with a working copy of wm6 on your wm5 deivce.
**FYI: With the 4pda update, I didn't LOSE any installed apps, data etc. I just installed all the wm6 versions of any apps I had over the wm5 vers. Very awesome!
** However when I performed the pdaviet rom update I DID. But its okay I needed to do this anyway (always good to start fresh with a new os install)
Boot loader Key Sequences (confirmed on 2490b, 2790b, msg me and ill add more if needed)
Normal Boot loader Mode:
contacts + mail + reset -let go and press calendar to activate
White Screen Boot loader Mode:
contacts + itask + reset -let go and press calendar to activate
Format P.S. (hold down until activated)(screen will say formating p.s. when activated):
contacts + messaging + power + reset
OR (I had to use this to format the p.s. after the PDAVIET rom upgrade)
calender + power + messaging + reset, release reset - release all
