Hardware differences? - EVO 4G Q&A, Help & Troubleshooting

I have seen multiple posts on how there is a different screen from 002 to 003, but what about everything else? Whats the difference between 003 and 004 and what does each one entitle to being different? Does it matter if you are running 004 and put on a rom that doesnt say if its only for a certain version?
What i did was i rooted and installed myn's warm twopointtwo on my cousins 004 evo and now his camera will not work. Is this because of the hardware version or is it something different?

What exactly is happening when you try to use the cam? does it crash and go back to the home screen or does it just have a white screen instead of showing the camera view?

the main difference in the hardware version is the type of screen that you have (epson or novatek). I don't think that there are alot of differences other than that.

The camera will not start up most of the time and when it does it will be a black screen. It still has the interface to take pics, go to gallery and the settings menu but even if you take a picture its black

The Hardware version isn't a guaranteed indicator of which screen type you get; there are Novatec and Epson screens across all of the hardware versions.
The differences are subtle; slightly different material for the back cover, different height for the power button, etc. Hardware version 004 I believe does have a slightly different camera module though. Specs are the same, but it's a different model number. I don't know the exact model numbers specifically, though.

What version of warm 2.2 are you installing? For 004 hardware it needs to be rls4 or rls5 as they will include the new camera drivers( most 004's have a different camera)

[Q] Radio Subsystem Issues???

I have recently noticed that one of my Evo's was draining the battery a lot faster than what I would consider normal. I started using power tutor to see where the power was being used up and it turns out that the "Radio Subsystem" was at the top of the list with like 30% or so. I ran the same type of test on my other Evo and it was no where near that. Can someone with knowledge please give me an idea on what is happening? I am running Warm TwoPointTwo RLS 3 on both with King #9. All other settings have been set up the same. The only difference that I have noticed is that the newer phone is on hardware version 0004 and that is the one with the issue. Any help would be greatly appreciated.
According to Sprint revision 0004 phones have slightly different hardware, namely a different camera. It is possible that the radio received a tweak as well. Try flashing the stock kernel from the 3.30 software version to see if this fixes the issue.

Thank you very much for the information. I actually downloaded the HTC #10 kernel last night with that in mind, but figured I would ask around and see what was brought up. I thank you for your reply and advice. I am going to flash the stock kernel tonight and post a follow up in a few days.

Is there a way to identify the camera chip?

I have a rooted EVO with Hardware Version 003 and was curious to know if there was a way to identify the camera chip in my phone (as I just found out that some of the 003 versions have the same chip that is in the 004 and therefore would benefit from the 3.30 OTA)
Thanks in advance..
What's the difference between the new camera chip and the old one?
Sure there is, just take your phone apart. Or you could try one of the older ROMs and see if the camera still works.
I was told if you are able to run a custom Kernel and your camera still functions properly you have the old chip. Don't know if this is true being that I got a 0003 Evo days before they rolled out the 0004's, so I would think I have the new chip but all old roms and custom kernels work fine for me. I'd also like to know what the improvements are regarding the new chip cuz my camera is ****...

Yes it is true. I have a 0004 version phone and my kernal only works with Myns rom with the #17 kernal. I have tried every other kernal and its a no go. Only a black screen.

In what ways is it better? If it is "better" at all?

Sounds like a downfall. Wanna trade? haha
I've heard that one camera isn't "better" than the other but rather, HTC had to go to a different parts supplier.
If anyone knows any different, please add.

If HTC swapped chips with out upgrading, they really have their head up their @ss. IMO that's the Evo's only downfall, the camera with my a500 killed the Evo cam I think my i880 did too.
I have 2 EVO's, one with the new chip and one ithe the old chip and 3.29 software. Bought them the same time. There is a huge difference. The new chip focuses quick even in low light. Almost impossible to to get a blury pix, even if moving while pressing the shutter. Tried with Barcode software. On small barcodes the new chip grabs the code and on the old chip you screw arround forever. Also the color accuracy is almost perfect on the new chip. On the old one it appears to accent blues. HTC is trying to cover it up and claims there is no difference in cameras or software, only a different vender for 2 months and now they are back to the origional camera. That sounds like a crock to me.

HBoot 2.02, HW ver 0004, custom kernels?

Pardon my ignorance here, but I just swapped out my Epic for an EVO, and I can't seem to find a solid answer for this:
I have a Ver 0004 EVO with HBoot 2.02, and after checking out my evoinfo.txt, it seems I have a Nova screen. Is there any way I can find out what version of the camera I have, so I can see if I can install custom kernels or not? I'm assuming that since the drivers source code wasn't released yet, there are still no custom kernels for the new cameras. I'm currently running MYN's with HTC's 17 kernel, s-off, but to be honest I'd love to try one of the Desire HD roms, or CM since I had it on my Hero.
Also, I'm still within my 30 days and have NO issues with swapping my EVO until I get the hardware version combos I want. What are the differences between the nova and epson screens? If I have a hardware 0004 phone anyways, should I be looking for an Epson screen over the Novatek, or are the Nova screens better? Picture quality, backlight, color saturation, etc.
Thanks in advance for the help guys.

If its a version 4, you have the newer camera hardware.

nova screens are a little brighter, and have more of a blue "cool" tint to them. epsons have more of a warm tone, and the whites look a little yellow.

Being an employee has its privileges. =)
OK, so look for HW 0003, with a Nova screen. Sad part is, the phone I originally swapped out was that combo, but there was horrible light leakage.
I didn't know 0004's had nova that must be very rare I still can't tell which I have the dmesg letters hurt my eyes
Swyped from Eva running Myn's RLS4!
So wait, Nuggy, you have HW 0004 and a custom kernel?

[Q] Any time I flash a kernel my camera stops working

I followed the root guide here http://forum.xda-developers.com/showthread.php?t=829045
and am running the sprint lovers rom but....
I am ok without Fresh but not ok with the stock kernel the battery drain is horrible..
I have tried the SBC kernel, and the netarchy-toastmod kernels.. if i flash either one of them in any flavor.. my camera stops working
I had a V003 evo from June but it had the purple hue screen and was gathering dust under the screen as well so I picked up a new one for $140 at radio shack and sold the old one.
the new one says V003 but honestly anytime i flash a kernel other then what comes in the above link my camera stops working so i am thinking it may have the new camera hardware but be labled v003...
any suggestions, feedback, options?
thanks in advance!
EDIT:
Phone info:
Hardware V 003
Baseband 2.15.00.11.19
Kernel that works 2.6.32.17-gee557fd #15
Build: 3.70.651.1
dont remember how to itentify my panel if that helps remind me how ill gladly share
It most likely has the new camera. The new source is needed to get it working on custom kernels. 003 and 004 have this new camera in it.

Wife's newer EVO takes better pics/stronger flash

Is there a known issue here with newer evo's vs older. Bought hers last december and mine was from the july before. In recovery, it says we have the exact same specs and versions. Her flash is noticeably stronger and takes much clearer pics. Very frustrating. Her screen seems to be a slightly different shade as well. Just wondering if there was anything I can do with the flash. Thanks
Recovery won't tell you anything. In as Sense-based ROM, go to menu > settings > about phone > hardware information to see the differences between yours and your wife's phone.
Honestly, I don't think there's anything you can do about the flash, as I don't have any experience opening up an Evo 4G and tinkering with the parts. Although, I'm sure the devs around here have a solution.
I had a newer evo with the 0004 hardware version and just had to take it to sprint and i got a refurbished Evo 4g with hardware 0002 and i noticed the screen was a different shade as well.

As far as the flash goes, not sure anything can be done about that. Different hardware versions have different camera hardware.
As far as the screens go, there are two different screen manufacturers, Epson and Novatech. The Nova's tend to be a bit brighter and have a cooler tone to them. The Epson's tend to have a tad lighter brightness, and have a warmer tone to the whites.
