Root [Boost Mobile] Fm transmitter

If the devs are interested, I can go out today and pick up some film for my canon eos rebel s, and can try to get some hi-res pictures taken of the mobo. It'll just take a day to scan them in. Any takers?
 
So, disassembled my phone, got a couple pictures of the processor mobo. Would the transmitter be attached to the digitizer? I'd rather not take that apart if possible. Also, the processor is housed under a MASSIVE metal plate, which at this point in time I am not sure how to remove.

Edit: Figured it out. What an easy phone to assemble and disassemble!
 
Well, I got pictures, as best I could. I hope they are high enough quality. I also wrote down the numbers on each "block" like ram and processor and stuff. There were hidden blocks under the metal backings as well :hmmmm::hmmmm2::thumbup:. I can't wait to develop them and have you guys find out.....;)

I'm all over it. :D
 
So, learned that I need to use flash when I use my film camera...never really done it before. However, I do have at least 2 salvageable photos...I'll have to disassemble and retake photos. Sorry!
See Below:

On the photos where the metal shield on the front part of the motherboard (not the camera side) is removed, you'll notice a metal cover that seems like it shouldn't be there. there is indeed a chip under that of some kind, maybe just a transistor, and one on the other side as well. Also, sorry about the poor quality :( I'll post the numbers and letters for each block when I upload the others.

THANKS SO MUCH!! :D :party:

Not to make demands of the first person willing to supply what I need to figure this out or anything... but could you also get some close-ups of the chips themselves? To research this, I'm going to have to be able to read the actual numbers off of them. Thank you again!!
 
WAIT. My best friend will be coming on shortly to post a link. That link will bring you to his photobucket, where he used his S3 to take some ridiculously high resolution photos of everything I took apart. I hope they provide what you, I, we need to get this worked out! :D

Give'm a couple minutes.

Hey guys! Hope this link helps! It's a photobucket album of some pretty good pictures! If you click an individual picture to bring up it's page there is a magnifying glass on the lower right of the picture click that (and then again for some reason on the next page??) to bring it up in full size.

Hope this helps!

Thank. You. Both. :D

We've all been wondering about this feature, and I can't tell you how much this will help me investigate!
 
It's interesting to note that our Warps have a standard EFD for memory storage, which could be replaced (by someone with the proper tools and skill) with an 8GB module like this. Larger modules are available, but I believe only to OEM manufacturers and the like.
 
Did you get a look at the hidden blocks under the area I cut away? I personally am curious what they are. If you look back at the not-so-good pictures I got, you can see the metal panels. Cool that the storage is standard!

Yep, I'm in the middle of running the numbers on all of those chips. So far I have about half of them discovered :)

Hey, one thing... I think the Hynix chip is layered on top of another. Is there a way you can separate them and get a photo of the underlying one?
 
It's funny... I did this same thing a few months back with my s3 too... Lol... Was trying to figure out if our accelerometer chip was really the akm8962 when I was investigating rotation on cm10
 
Okay, here's a list of what I've found so far:

SanDisk SDIN5C1-4 - SanDisk SDIN5C1-4G iNAND Embedded Flash Drive
Qualcomm PM8058 - power management integrated circuit

8903CE - variant of Maxim Integrated MAX8903
Qualcomm WCN1312 - WiFi 802.11 b/g/n support chip

QTR8601 - variant of Qualcomm QTR8x00 platform

Hynix H9TKNNN4KDMP - variant of Hynix H9TKNNN4 family LPDDR2 RAM module, possibly stacked



Some other interesting reading:

Details on the MSM8x55 series of processors

A document listing of the capabilities of the Snapdragon family which mentions the FM radio support chip

A very brief description of what the PM8058 and QTR8600 support chips do





The important thing to note here is the presence of the QTR8600... this is in fact the chip which provides RF transmit and receive! So, now that I'm fairly certain that we have the chip... what are we gonna do about it? :)

Hack the hell out of it! It's the Warp section of AndroidForums it's what we do! :D

I would rather not dissect my ram, as my phone is perfectly functioning even after two of the previous dissections (rather not test my luck XD)

I did a little browsing around, and I'm fairly certain that the memory is low power ddr2, and mcp. It could potentially be replaced by 8 gig of ram if that is the case! (Page 8/12 of the Hynix 1H12 handbook).

a quick search of H9TKNNN4KDMP, results in this page: SK Hynix H9TKNNN4KDMP > Device Library

Also Merc, most of your links don't work on that post you made.

Oh, my mistake! I was thinking the Warp you dissected was dead. If it's not, then there is in fact no use in making it so! lol

I agree, the RAM seems easily upgradable since it all is of the same family, but the only thing is that I believe ZTE stacked the RAM on top of the Snapdragon core, and I have no idea how one would separate the two. I found the whole "stacking" notion unlikely until I saw Hynix has a page on it. They mention offering a package combining an applications processor stacked with RAM, both of which can be mixed and matched by the customer, being ZTE in this case.

I did find that analysis page, however I didn't feel like spending the $400+ they want for their report. lol I'm sure it would be incredibly useful though.

Also, links fixed. Thanks for the heads-up!


Regarding the chipset lawsuit, I see on that page that both the WCN1312 and the QTR8601 were mentioned in this suit and yet our phone still has a fully-developed WiFi feature as provided by the WCN131... why wouldn't they do the same for the QTR8601? Mysterious, to be sure...

I'm sure the necessary functionality coiuld be enabled in the system, but it would have to be done from within the kernel. Also, there's the question of how to activate it. I'm not aware of any phone with similar hardware to the Warp which had the FM radio feature, but if one existed, it could prove to be a major step in getting this feature on our devices. If one does not exist... well... let's just say the job gets a bit harder. There's a good chance custom code would have to be added to the kernel which would address the IO pins of the QTR8601 to access, configure and control the feature.
