I found a 'good' VOX ROM upgrade (the ones on the XDA FTP are all corrupt): RUU_Vox_HTC_WWE_1.15.405.2R4_220.127.116.11_02.83.90_Sh ip
Another upgrade ROM is the Dopod:
I used NBHextract.exe to extract both ROMs. The SPL bootloaders are attached.
NBHextract shows following info for the 1.15 Vox ROM upgrade:
and this for the Dopod upgrade:
I managed to back up my S710 using itsme's "bkondisk" tool and "prun" from his itsutils suite here
. Copy bkondisk.exe to /Windows on your device.
After running this on your PC
prun bkondisk.exe "\Storage Card"
following files are created in \Storage Card and a log file "bkondisk.log" in \
bk_00_0000.img - IPL : ONBL1 + ONBL2
bk_02_0005.img - GSM + splash + gsmdata + simlock + serialnrs
bk_03_0025.img - OS
bk_06_0001.img - SPL
bk_08_0205.img - userfilesystem
I compared a couple of these .img files with the .nb files extracted by NBHextract from an official RUU. The IPL and SPL look quite okay, but the OS is mapped totally different. So don't think you can just rename for example bk_03_0025.img to OS.nb in order to have a flashable file !! I have attached my dumped SPL which is version 1.16
Next mission is to find a 'good' (not corrupted) version of the RUU_Vox_HTC_WWE_1.15.405.2_18.104.22.168_02.83.90_Test .exe ROM upgrade. See this Excalibur thread
. I think the same applies to S710
With Dark Simpson's htc rom tool here
it is possible to create a flashable image file from separate .nb files. There is also Dutty's good NBHtool 1.1
yet, but so far I haven't tried it.
What we still need to have for flashing unsigned ROM images is a SSPL. See here
Alternatively we need a so called Update SPL (USPL) which unlocks CID and then allows flashing any rom to your device. The version for the ELF created by the brilliant moderator pof can be found here
. Since the ELF is very similar to VOX, I will study it and see if I can use it to implement a SSPL (software SPL) which allows us to also flash any ROM, but does not require to flash an USPL. I think flashing IPL and SPL is a bit too tricky atm.
