Question...
I have 128MB RAM in my US T-Mobile with the driver for using the upper 64M. If I had the guys at T2T swap my 32MB ROM for a 48MB ROM similar to what the older Ipaq's were using, could I use all of it with the kitchen? Would it be accessible by the OS?
I'd like to squeeze Fonix and Pocket Informant into ROM and there's just not enough room today.
Just a thought...
Hi,
I cant answer that question but could I ask you one?
Whats the driver to use the upper 64mb for RAM?
thanks.

I've just spoken with the folks at PPCTechs and they do not offer ROM memory updrades.
right........

The guys at http://www.pocketpctechs.com/ make a driver for it. They only sell it with the purchase of the memory upgrade and service.

Ok, let's say I have a soldering iron and an old Ipaq that I could steal the ROM from and put in the HTC. Any idea if we could use the extra memory for stuffing applications in using the kitchen :?:

Ok, first off, have you seen the inside of your XDA?
Second, unless you are good with multi-layered pc-boards and do not get anything else on and in the board hot, than you may (note may) be able to pull off the chip swap. Mind you not damaging any of the shileding and compromising the frequincy levels.
Third, are you really sure you want to risk your XDA by soldering ROMs that may not be compatible with the circuit in the XDA?
Hmmm
The point isn't if I can get the 48 MB ROM in the device :roll: , my question is specifically can I use it if I do? If we tweaked a kitchen to go above the 32MB current limit, will the XDA have any issues reading the additional ROM :?:

Read my above reply very carefully. It is very specific on the even if you could get it in the device that it may not work with the circutry in the XDA. Most manufacturers use ROMS in a device like this that are specific in capibilities and than design the rest of the circut around that. Now this doesn't mean the chips won't line up pin for pin, but even if they do you have to make sure the internal functions of those chips match the same pin configuration as the previous chips pin configuration. As in you may have 48mb ROM chips that have a Positive Power feed where it needs a ground for the XDA's Circuit. This plugging the chip in means dead both. Even if it is a match, the XDA may be limited to seeing only 32mb ROM as a physical barrier and anything more will produce an error in the unit.
IF you do more research in electrical design you can find this out and I DO recommend it than you can analyze the circut yourself and determine if it can handle it or not. Also, you need to "Cold" solder the chips. A soldering iron will destroy the board. At the least damage it as it was designed heat sinsitive.

Hi,
I like to upgrade Universals to 128MB RAM.
Unfortunately I don't have access to 64MB rams usualy.
What I have a plenty of is: HYB25L256160AC and HYE25L256160AC 32MB ram chips which universal originaly contain.
There is a spare place for 4 RAM chips in universal, so why not to add these.
I haven't seen this discussed anywhere. I even don't know sure if the spare place is meant for RAM (but most probably).
I have very advance skills in BGA resoldering, so I'm able to experiment.
What I need is someone who understand it more and tell me first if it's possible to use 4 chips there and maybe someone know if there are some hardware updates in the pins around (short circuiting or resistor adding).
And don't hestitate to post some reply even if you are not sure if it's right....
I need some brainstorming here.
Regards,
Shef

I can tell you, but it would be a lie
Try using the search, the empty places are not fpr RAM chips.
I'm looking for damaged Heralds/Wings to experiment on. Cracked screens, etc. Anything that can't be use anymore, even if it's bricked. There's a lot of things I want to play with but I don't want to damage perfectly usable phones with.
This is for people who are going to be throwing away their phones, not for people who are looking for a hope that I will fix it.
The reason this is in the development forum is that this will be so that I can further develop theories.

what exactly are u going to do with them
i am wondering the same thing.
i think i might know a guy that didnt take care of his wing.
last time i saw it, i prayed to god. lol.
Open it to find out what kind of memory chips it has.
Use this information to know if the storage and extrom are stored within the same DOC chip and whether I'll be able to reformat it and merge the two for more storage space.
Work on a WM Standard ROM.
Etc. Etc.
I just need one that can at least boot, even if you can't make calls with it.

No, like fzzyrn mentioned, it would be software based. I just need to open a phone up to see what kind of memory flash chips are inside so I know how it's setup and how I can reformat it and merge the extROM with the storage.
Has anyone ever thought about whether it would be possible to increase the ram/upgrade memory in a G1. As outlandish as this might sound.. similar things have been done for a variety of devices.... if possible it would probably be the number one speed booster out there? or are there certain limitations out there that would make that impossible... Anyone ever opened up a G1?
This might be what you are looking for
http://forum.xda-developers.com/showthread.php?t=566410
Theres some ram on the g1 that isnt being utilized by default.. this hack, for specific roms, can push the g1 to use more of the rom that it initially comes with. as far as a PHYSICAL upgrade im not too sure how that would work out.. never opened a g1, due to warranty void
This does happen a lot nowadays. Original Xbox's (before v1.6) had extra 'spaces' for RAM chips.
Simple to do, if you can find the right RAM for your device, which was hard enough for the Xbox until a German manufacturer was found.
http://www.xbox-linux.org/wiki/Upgrading_Xbox_RAM_HOWTO
Edit: Also remember, this only works if there is an extra 'space,' piggybacking does not work 99% of the time (and I doubt there would be enough space within the housing...)
so the question would be is there anyway to open the g1 remove a ram chip and solder on a higher capacity one.... I mean wouldnt that be awesome...

I was actually referring to how the Xbox got more RAM, by adding ANOTHER RAM chip. Possibly higher capacity would work, but I don't know **** about drivers or software compatability blahblahblah. I'm only good for actually putting it together not knowing how it works :3

There is nowhere to put it.
Ram and rom come integrated on the same chip: samsung k522f1gacm-a060
You need to find a compatible chip (as mentioned, the one from magic or hero *might* be compatible), you also need to program it with something... which you may need to hack together since there is no such thing as a dream with 256MB ram, etc.
hmmm....ok... so not possible to replace the chip flash a custom rom? Maybe we can have some bricked g1's donated to see what can be done...

I never said it wasn't possible. I simply said that what is there must necessarily COME OFF in order to put another one in its place.
And yes, you most definitely CAN program these chips outside the board, as long as you have the right equipment to do so, but the big question is to "program it with WHAT?".
Well according to this video our phone uses standard DDR ram made by Samsung. So I belive this is very possible.
Anyone wanna donate a bricked phone for tinkering hehe.

As lbcoder has stated, finding a compatible chip isn't the problem.. it's a matter of what do you program onto the chip? Simply replacing the current chip with a blank one wouldn't do anything.
WELL, I don't know if this will work but I tune cars, where you use a eeprom reader get a dump off the old chip into a hex editor and then just burn it onto a new chip with changes made and just stick the new chip with new maps on it.
Would it be possible to do something like this with this chip? Just do a complete dump of one to another?

Yea thats the way it would be done. You'd have to hex-edit the dumped rom to address the right amount of memory for the new chip and it should work. I'm certainly not going to be trying this myself but it would be an interesting experiment.
Anyone know someone who has the smarts to do that... find me someone and I'll find you a few bricked g1s ...probably the only way to get them unbricked anyway.... or I have a g1 here whose wifi does not work. I bet you there are a ton of g1s out there where this or that does not work but that would be fully suited for something like that.
Anyway lets find a genius or a few that are brave enough to go where no one has gone before... I'd be pretty certain, that twice or four times the Ram would be a pretty dramatic experience.... imagine the possibilities with ram discs.... etc...

Believe it or not guys, my wife can do this. LOL. (I did marry the perfect woman, she also fixes my cars, folds the laundry and gives the best blowjob on earth). I digress <grin>.
If someone wants to donate a couple of bricked phones, I can get the chips swapped out. The issue of hex editing doesn't scare me at all I've been doing that for years, but finding the right addresses could be interesting. I'd probably need help with that as it is a lot different then bipassing a cd check on a video game
i work with embedded devices and here are my 2c about this, but take this lightly, I havent looked at how the G1 is setup on a board yet, nor do I know what hardware it is running.
if there is external ram, then perhaps it is a matter of swapping out the chips, given that they have the same pinout/packaging, etc.. if that was the case, you wouldnt get even another bit of more addressing because to get another bit, another wire is required to address it.
if the ram is internal on the microcontroller, then it would need to be swapped out, and good luck desoldering/soldering a BGA chip by hand. if you manage to find a new MCU with more internal ram to put on, the pinouts would have to be identical or else things might not work. additionally, you would need to have some method to kind of bootstrap the MCU because they typically come blank from the manufacturer.
Ok this is getting interesting... the easiest way to find out is probably contact HTC.. does anyone know someone, or is there a way to contact an engineer... or can anyone look up the specs? If it is using standard ddram by Samsung.. there might be a possibility.
Let me see what I can find for bricked G1's than we might have redir's wife take a look at it.. or John5788, if you'd volunteer. PM me your contact info...
We could just check the service manual, no?
edit: i tried to upload it, but the upload script here blows..
mediafire to the rescue! [download service manual here]
i just looked through the service manual, nothing specific about the ram/mcu locations. everything is just located on the mainboard without any sort of diagram. the people that look at the service manual dont need to know the device at that sort of hardware level.

First, there are only two tabs.
Second, they are brass, not gold.
Third, I believe they are springs designed to keep the door under tension and facilitate its removal.

The ones you are talking about are on either side of the phone when you take the cover off. There are corresponding spots on the cover. Mine are a silver color. The ones the original poster asked about are indeed gold in color and number in three. I say they are there for testing purposes. A faster way to connect to the phone maybe.
The HTC carkit mount comes with a special battery door cover, that the mount snaps into, and also connects through...so it's just a guess (I don't have the carkit myself), but I'd think those are the pins that the car mount uses to pass data, or current for charging

Yes, i would say the same thing. I would guess they are for the car kit because the base of the car kit has power running through it
I would have to jump on the bandwagon on this one and say yes to the carkit feature, due to the pictures found here:

Lets now leave the Emotional part and get to the Fun Tech Part.
I did find out by talking to T-Mobile Rep Tier 2, it "Is" a Test port, has communication I/O, and can be used for Kar Kit with BlueTooth/bottom micro USB port.
The "Test port" is what I am interested because if you can talk using USB architecture then you can do other things with it? example; Robotics, card readers, Web Cams and many more?, I have been reading the Registry for any clues, or Info on this? That is why I brought up this topic?
The "Test port" is used at factory for reliability testing in a burn-in chamber that they use for getting faulty units out of the mix?
This is what I have so far? if anyone else can add pertinent info it will be greatly appreciated.

You did manage to make my ignore list though. Congratulations!
Yeah, those spots are where the back cover used with the car kit connect to the car kit. I never heard of them being used for anything else, but it might be possible. I think power and audio can be sent through those. It also tells the HD2 to go into the navipanel when carkit is connected to it. When looking through the registry, look around the navipanel stuff. It would be cool if we could find some more uses for that port.
More info
I was told that the center tab is data negative and the left tab is data positive and they use case for ground, now I need to figure out how the USB interface works with this? I have been searching the T-Mobile USA HTC HD2 threads for info, but have not found anything? will try the other HD2 original thread to see if anything there can help?
Maybe there is a ROM list of commands supported somewhere to help in the communication interface,
I rigged a 3 wire interface for monitoring only I don't want to put any signals in yet until I understand how it is working?and I am using a program called Boxcar to send signals out of which I can see changes but have yet to determine exact output? This is going to take some time?
Boxcar is a WM2003 program but seems to work with WM 6.5 and is good to use because of the wide variety of interfaces it can use withe the USB transceiver module, Temperature probes, pressure transducers and DAC's Digital to Analog Converters, I also have a serial module but I don't want to go that way? USB is the preferred faster interface.
But ultimately my goal is to make my own Kar Kit interface with a greater amount of control of what it does?
I had already built an Interface that works well with the Ford Sync interface on my car (I use to work for a company that built TED Air condition seats for Ford so I am familiar with the system), but that is using my Laptop and I would like to do the same using only the HD2? Baby steps.
I don't know if anyone here has the knowledge about the HD2 to help me? as it's a new device and info is minimal? I may have to wait until that info level is reached?

Good Grief,
You need one of those things in your post saying "Do not try this at home" I can see it now all these folks sautering wires to the backside of their phones.... And then saying "my phone just smoke checked, what do I do"
Say I have a MSM8926 device (Motorola XT1045) , and I succeeded swaping the original 8Gb PoP RAM IC with a 16Gb module of same technology (lpddr2 etc...), what changes in the software side (firmware, e-fuses perhaps?) need to happen? Please avoid answers prompting me to look at the SoC datasheet, I know it's all there but I don't have access to it yet (I don't have access rights to those threads yet and I just started thinking about this). Thanks!

Okay how the hell did you solder out pop ram chip.. And more importantly how did u know u have succeeded and where in the world did u get 16 gigs of ram... I'm not accusing u but maybe ur method of doing this help us know what exactly we need to give u

16Gb (gigabits, or in this case 2 Gigabytes) on a 168-FBGA 12x12 PoP can be easily sourced from china, one good example is K4PAG304EQ-AGC2. About the PoP rework, if you have experience and time to build a jig then with the right tools it's perfectly doable. Given the current state of the smartphone market this is an effort that is worth my time. Like I said, I would appreciate very much any help on the soft/firmware side.
Okay okay.. Heard u loud and clear and would like to point u to go on the official motor thread. Not to mention cheers on doing that u literally made phones modular
Starting points
1)find custom kernels for ur phone. There is Dev support
2)ask the dev or make ur own tweak to modify the kernel to check for 2 gigs of ram (sorry for reading gigabyte instead of gigabit)
3)once kernel is finished. Grab a fairly polished rom
I'm really sorry if all this is a Lil vague but I really haven't seen this or heard about this before . I have seen graphics card vram solders not work pretty well.. And I'm still reeling from the fact that u accomplished this. However just follow it up. Kernel which u can modify(again I'm saying that u shud modify Coz more than enuf sure that pop wasn't isn't plug and play) then any room shud plays nicely with minor tweaks which the community can take care of
Lastly.. Would like to see a video of u doing this.. Would be very educational for hardcore modders
Dude please some pictures
