Hello guys,

Anyone can explain these information for me? i'm just a novice in this area. thanks.
P/s: what is SD card level 4? and what is level 6? what is the difference?
i have just rooted my G1 successfully with z4Root and Superoneclick, but i really don't know where to begin my rom update? which rom is stable? and how to prevent from being bricked? Is there really a software way to unbrick g1?
Model: Its yout phone
Kernel: The linux kernel, on this kernel is your rom builded on.
Radio 2.22.23.02 : your radio version (stock)
0.95.000 hboot : your hboot version (stock)
Firmware: your android version
If you want to flash a Rom, use this guide from me or this guide from ldrifta (and me)

[Q] Security Unlocked - Custom Roms Question

Greetings.
I also just recently got an HTC HD7 (TMOUS) with the following info:
OS Version: 7.10.8107.79
Firmware revision number: 2250.21.51202.531
Hardware revision number: 0002
Radio software version: 5.71.09.02a_22.51.50.21U
Radio hardware version: A.12.0.D4
Bootloader version: 5.12.2250.0(135916)
Chip SOC version: 2.2.5.0
Bootloader screen says
Security Unlocked
PD29*** SS-BC (4k)
SPL-5.12.2250.0(135916) NMG
MicroP(LED) 0x07
TOUCH S1(v2.B, #1625)
I'm fairly new to custom roms/flashing and would like to ask if I can flash any custom roms with the Security unlocked bootloader or do I still need to downgrade my SPL as to avoid bricking the phone.
Thanks in advance.
you still require downgrading OSPL in order to XSPL your device.

You are doing it fine!! when the phone reboots, you install the custom rom.
Just use the nearest number, up or down.
