[RESEARCH] Sensation Partitions / Firmware

---

While looking at the firmware.zip file contained within the latest OTA, I started to wonder if we are overlooking important partitions. I'm fairly convinced we are at this point.

Here's what the original RUUs contained for Pyramid:

adsp.img
android-info.txt
boot_signed.img
dzdata.img
hboot_8x60_1.17.0008_20110513_signedbyaa.nb0
radio.img
rcdata.img
recovery_signed.img
rpm.img
sbl1.img
sbl2.img
sbl3.img
splash1.nb0
system.img
tz.img

And here's what's in the latest OTA firmware.zip

android-info.txt
boot.img
hboot_8x60_1.18.0000_20110802_signedbyaa.nb0
pg2fs_spcustom.img
radio.img
rcdata.img
recovery.img
rpm.img
sbl2.img
tz.img

Some of these are obviously known quantities. After poking around in a hex editor, I think rpm.img is relevant to us, as it appears to be chipset-related firmware. The varying reports of black screens with custom kernels could very well have to do with the lack of people flashing this image.

tz.img was referred to as "Trusted Zone" in HBOOT, so I figure we'll want to stay away from that one. The sbl* files appear to be part of the boot loader (Secure Boot Loader would be my guess for what it refers to). I have no idea with pg2fs_spcustom.img is. rcdata.img is literally text, which appears to configure the radio (this one has been known for a while but is not commonly discussed).

Anyhow, I flashed the following bundle, which includes the latest radio, recovery (with recharging fixed) and rpm:

Obviously do so at your own risk but it worked fine for me. If you're getting black screens, this is probably worth a shot. If anyone has input on what the other partitions actually do, chime in here as that's the purpose of this thread.

If we flash your attached file will we need to reflash clockworkmod recovery in order to flash custom roms? Also are there any benefits to those who are not having black screen issues.

Provide MD5 sum for a package like this please.

Ok, so all we have to do is flash that bundle to get the most recent radio, yes?

I've successfully flashed the file, and here's my md5:

Everything seems to be working fine. The new baseband info is as follows:

Why are the Ota partitions like boot and recovery not signed anymore?

confused...

I have flashed it with the unity v6 kernel that Baadnewz posted on his thread, with his latest 2.2.1 ROM. I experienced a black screen today, so I will report back tomorrow if I get any issues (or not out of courtesy) You Kernel guys are truly geeky in an amazing way

Decided to test this also. All working well here, thanks for the effort. Will report if any problems occur.

does anyone see an diff in speed or signal gain ? or is it just for the black screen issue ?

What exactly is the black screen issues that we are referring to here? I had a black screen after I debranded my Bell Canada sensation to 1.35.401.1 WWE unbranded and then performed revolutionary again and then tried to update to 1.35.401.2 via the OTA. Would this help address that issue? I then had to flash back the the 1.35.401.1 via an RUU to get it fixed. If I try to straight upgrade from 1.35.401.1 I always get an error status 7.

Thanks,
