Need your help for a few files

[dspl1236]

I started to convert the VS920 Spectrum Bootloader Pwnage tool to work on my VS840 Lucid.

I hard bricked my device testing this. pushed the wrong firmware to it.... so I am missing 6 files that were also needed for the unlock.

If you are on ICS and rooted and willing to help it would be great. PM me for details

You don't need the ICS files for the unlock. You need the GB files (assuming GB was an unlocked boot loader). You also need a custom kernel as the sfuse will trip if you try and run the stock ICS kernel without the locked boot chain.

i know just enough to be super dangerous.

would you like a gb cwm backup?

I'm good. Assuming that /system rip you linked me was ICS, we should be good to go.

You'll notice that you have an extra partition because you have internal storage. I've also found that you have the files needed inside the .cab you get from LG to use this method to downgrade/upgrade/restore your phone as long as you can get into download mode.
http://rootzwiki.com/topic/17823-flashing-lg-signed-firmware/

Just make sure to grab the firmware version for your phone. I saw V6 links floating in your forum. Here are V5 and V7

V5: http://csmg.lgmobile.com:9002/swdat...K/VS840ZV5_00/VS840ZV5_00.S5_00.P58013.R5.cab

V7: http://csmg.lgmobile.com:9002/swdat...S840ZV7_07/VS840ZV7_07.S7_07.P58015.R5.01.cab

So, here is what you need and I'm leaving this info public for group effort as I can not dev without a device and I'm not looking to gain a new phone.

Take the /system partition from ICS and build a kernel that will boot it. You will want to be on the unlocked GB build when trying the rom. It will boot when you get it right as we did the same thing when our ICS leak came out for the spec.

Once you have a bootable ICS rom, then you can take the Pwnage tool for the spec, and replace all the dd img files with those from GB. Be careful with mmcblk0p7. This one needs to be flashed first, and if done wrong, will cause a brick. This controls the initial boot up and tells the phone to either go to download mode, recovery, or to the boot loader. Recovery can be replaced with your recovery currently used for GB. Boot will need to be replaced with your custom kernel used to boot the ICS rom. If anyone has questions on this info, please let me know.

Edit: I was given a stock boot.img and didn't realize it. I'll take a look at it this week to see what I can find out.

 

[dspl1236]

This is a great step for Lucid owners Neph!

After I get a new Lucid I will be experimenting with this. I had intended to revert back to GB and setup cwm to play with ICS... then i got over zealous....

 

[Neph81]

Can someone with a Lucid please run the following command for me (either in adb shell or terminal)

getprop ro.board.platform

Everything I'm seeing so far says that you guys may be closer to the Spec the realized and if you're running the MSM8660 , there is a very good chance of porting CM10 over to you.

 

[dspl1236]

Has Adreno 220 and MSM 8660 but only at 1.2 ghz...I see no reason why we couldn't hit 1.5 with some kernel work. Gpu and ram are even the same speeds. This is literally a smaller spectrum.


Happy holidays guys, I am out.

 

[Neph81]

Someone still running GB needs to test this and the person testing should be familiar with ADB and how to get into CWM recovery via the button method.

http://androidfiles.massivefilehost.com/lucid/lucid_ics_b1.zip

Go into CWM and make a backup.(critical because this may not fully boot)
Install rom
Reboot

One of three things will happen with this.

1) This will boot without a flaw and we can move on to making a boot loader unlock tool.
2) This will boot up, but not into the system. ADB is set to start at boot, so we should be able to get a logcat out of it.
3) Doesn't boot and we'll need to write a new kernel.

I look forward to hearing results from someone.

I downgraded to GB, rooted, installed CWM and tried this out. It seems to boot but the screen is black. It does play the startup sound and it is busy, but there's nothing on screen. I'm trying to get a log now but I'm not sure what the device is doing. USB is connected and it seems to be totally working except for the display.

Here's the log I got, I eventually just turned it off and reinstalled stock ICS for now, but I can test anything else later.
http://wiisixtyfour.webs.com/files/log.txt

 

[Neph81]

Thank you. This is a great step forward as it proves that the kernel can boot the OS. It's just a manner of fixing a few glitches in the ICS I was given.

Edit: The blank screen is apparently due to the kernel not being able to open the frame buffer. This is causing the OS to not fully boot either. Both seem like fixable issues.

 

[Neph81]

The log shows basically everything booting up fine except for the video driver. Can someone possibly get me the dmesg from the kernel after the phone has been on for about 2 minutes? This seems like a very small error and potentially it will be right into CM10 from there. We'd just need to add support for your internal memory.

So what you need help with

Anyone have an alternative link to the ZV7.cab download? Thanks.

Try this one for V8 (Also ICS): http://csmgdl.lgmobile.com/swdata/WDLSW/LGVS840/AVRZBK/VS840ZV8_05/VS840ZV8_05.S8_05.P58016.R5.cab

Thank you so much dude! I had V6, but I didn't want to have to go through 3 OTA updates again. You're a lifesaver.

You should be able to find all you need in my Lucid Repository. The b4 zip is actually cm-10-20130823-UNOFFICIAL-vs840.zip.
