Is there anyway possible to either open up the XDA and change out the SD slot or some kind of other modification to change it to work as an SD I/O I would do anything to make this work.
Probably possible..
It would probably require:
1. Enough technical insight to produce your own customized device from scratch.
2. A new customized motherboard and reconstructing the bus structure of the whole motherboard
3. Enough money to buy at least 50 XDA IIs units..
4. Building your own customized ROM for the XDA with SD I/O support.
5. Plenty of time
So, as you see; it is possible.
Is it doable? No..
difference between sd interface of
xda1 and 2 is
with xda1 they have an extre chip to control the sd interface
with xda2 it's nativ in the cpu xcale series
so it would require an sd interface chip which was 100% the same size
and 100% the same "leg" connetors
and thats just the hardware
then you had to get all the drivers for the SDIO running
and hoping that not too many of them was locked in the rom
the time and the skills
and the chargning one self for using that much spare time
would be better spend on just about everything else
workwise to buy a new pda which had SDIO
just my 2 cents
on that note, anyone have an old xda 2? or anything close with and sdio slot that they'd trade or sell?
Okay, let's just say, in a completely theoretical question, does anyone know the hardware in these devices well enough to know if it's at all possible to upgrade RAM by replacing the stock chips with higher capacity chips? I'm just curious if the system would be set to a certain amount so that an increase wouldn't even be recognized, or if the chips were special in some sort of way that would prevent them from being swapped out or anything. The OS would certainly not care, but what about the actual hardware or system settings?
it all comes down to memorymap
http://en.wikipedia.org/wiki/Memory-mapped_IO
if a nother address room for another addressable device
is places close to the address room of the mem then
it would overlap and not work at all
also one have to be pretty good with a solvering iron to solver these smd chips out
they were never ment to and is by no means solvered in by hand by the manufactor
this is possible on some devices (heared about HPs being upgraded), and impossible on others (like universal).
Yes, as mamaich said.
iPAQ Hx 4700 can be upgrade RAM to 128 MB by using iPAQ 5550 128 MB RAM on board.
Or using upgrade service http://www.the-gadgeteer.com/review..._to_128mb_internal_ram_upgrade_service_review
Interesting. Alright, thanks. I was just curious about the architecture of how the hardware worked in the devices. While I'm crazy enough to try such a thing (and fairly experienced in PCB work), I certainly have no intention of doing so until my device is past any type of warranty period. Even if I didn't screw anything up, I'd be screwed if anything else did screw up later.
The Dell Axim X50v and X51v (probably the non-vga versions also) can also be upgraded to 128mb RAM (vs 64mb stock).
I was on the fence about buying the 3600 when I read of many people having problems with the screens going out, system slowing down when touching the screen, and the metal peeling, slow performance, ect. I didn't realize that there was a new one, 3600i. Has anyone had any similar issues with it? How is it compared to the 3600 as far as reliability? I believe this would be my perfect device if it just supported SDHC.

The P3600i does support SDHC, at least to 4Gb. Can't test higher capacity mini-SDHC cards yet, not available here.
Oh, BTW, the Quick Fix GPS cab file does work, despite the "placebo" sceptics. Tested exhaustively now for 4 weeks. It downloads ephemeris data from http://www.htcusainc.com/clm as packedEphemeris.ee for NMEA mode. This is exactly, precisely, the same data file for SirfIII GPS in NMEA mode.
TTFF is now 30-60 seconds. Before, 5-10 mins, about which I had justifiable criticism.
Regional setting HKLM\SOFTWARE\HTC\QuickGPS\region
needs to be correct. I'm using AU for obvious reasons.
The P3600i is now in my view as close to perfection as I may wish.
ROM and RAM higher than 3600,so I think the speed will be higher and stable when run large program.for example,Map guide,etc.
Ian,
I am surprised to ear that P3600 support SDHC 4Go because i bought mine 2 weeks ago and before buying a mini SD i put the question to HTC and got this answer:
Dear Sir,
Unfortunately the HTC P3600 does not support the mini-SDHC format cards, only standard mini-SD. The maximum size you are able to use in the device is 2GB.
Thank you for your enquiry, Should you have any other problem, please do not hesitate to call us. Your Local number can be found at http://www.europe.htc.com/support/csbyphone.html
So i was just prepared to buy a 2GB mini SD, can you confirm that a 4GB SDHC works on a long term basis?
About quickGPS do we have to launch it only every 7 days and nothing else than starting normaly our GPS software (tomtom)? I tried qGPS but i do not see any difference in the fixing time after starting tomtom.
My p3600 Italian version supports SDHC. I'm using a 4GB right now.
8Gb sdhc
Hi!
I using 8Gb micro sdhc card with minisd adapter, and it's work in my p3600.

There is the P3600 according to HTC and the P3600 according to XDA-Developers.
The P3600 according to HTC: WM5, no SDHC, and 4GB-Mini-SD (without HC) is not really a standard so nobody will assure compatibility.
The P3600 according to XDA: WM6, SDHC-compatible due to a new driver.
Beware: There are a lot of different flavours of WM6, as they are built by different persons, not directly by HTC. Their reliability is very different, read the threads to judge whether a built is more shiny, more stable or both.
QuickGPS does not work on the P3600, the standard rule is valid: Don't move until you get a fix. You might save up to 10 minutes.
Have fun!
Hello everyone!
I now have a I-Mate JasJar and I love it!
However, it is a 64 mb unit and I am considering the upgrade!
So I wanted to ask everyone that has already done the upgrade if they think it was worth it?
Also I would like to know where you can see the improvment the most?
I like Nav n go Igo 8 navi program and my device clearly
does not have enough memory to run it properly, will it help to do the upgrade or is it so that the graphic card is not quiet up for the challenge to be able to show 3d terrain and everything else in Igo8?
So basicly I want some coments from you guys, what works after the upgrade and what does not work?
For me I am considering either to do the upgrade or to buy the Touch pro when it cames out, but the thing is that I like this device to much to sell it!
So is there any hope for it? Is it going to be as good as the rest of the devices that has more memory (like tytn II), or is it just not worth it?
Oh and buy the way, I do own a tytn II so I know all about the missing drivers and stuff, the fact that it has a gps is great but somehow I dont mind that my universal does not have gps becouse I have an external gps anyway and it is much better then the built in gps in tytn II!
not get mine upgraded yet but I won't even though the xda exec might be stronger and faster / more stable? I have no idea but I never want mine to be disassembled or replaced sth. I want it to be still original and untouched inside, I love software and OS modding but no hardware modding seem to be interesting to me.
Well, I have send my Qtek9000 yesterday to the shop in Germany to get it upgraded...
Why, becose I am running IGO8 and have not enough Ram to run it properly.
I hope it solves the problems I have running IGO8 like the 3D map wich somethimes dissapears after a while...
I let you know my experience after the upgrade...!
Actually, if you install many softwares then ROM is more important because even though you can install the softwares to the memory card but many programs would install either in part on in full to the ROM
You'll reach a stage whereby you cannot install programs even to the memory card because you'll face 'Storage Memory Low' error
I wonder whether it's possible to upgrade the ROM too say to 512MB?

Don't know if you are familiair with the memory of computers, but...
See the SD-card as the harddisk. That's clear.
See the ROM as memory that you cannot use for your own (exceptions are Flash and extended memory, but those are 'hard disks' too)
So, all 'hard disks' are used to store stuff onto. This can be programs, images, databases, whatever.
See the RAM as usable program memory (the RAM of your computer - might be 1Gb or 2Gb or 4Gb)
The 128MB is RAM, so only to be used as program memory, memory used while running programs.
Each program that is installed costs NO RAM, except when you (or the OS) run it. Drivers only consume program memory when they are loaded.
So, installing eg. a large game won't change anything to your RAM.
Most programs can be installed to SD. Only a few cannot. However, often can be tweaked (eg. Opera, Wisbar) to run from SD without any problem.
I would very much like to have 128MB too... I was under the impression that the store in Germany would not do this anymore (it is not on their web site)
So, CFDS, when you get the Universal back, please inform us of its state!
RE
I think you're mistaken
I'm referring to the storage memory vs the program memory.
The Uni has 128 MB Flash ROM and 64 MB SDRAM. Similarly, the SAMSUNG SGH i900 has 256 MB Flash ROM and 128 MB SDRAM
Here's the spec for the Uni (QTEK 9000)
http://www.qtek.nu/europe/products/9000/specifications.aspx
Are they really doing the upgrade?

Thanks for your reply, yes Igo8 is why I am considering the upgrade myself!
Please let me know when you get your device back, I would really like to know how it works with Igo8!
Also I would like to know to what shop in Germany you sent your device?
The only shop I know of is this: http://www.srsgmbh.de/en/index1.html and I dont see that they can do the upgrade anywhere on their site!
I wrote them an email asking them if they can do it and what the cost will be, but so far I have not recieved any answer!
Is this the shop you are reffering to or do you know of any other in Germany that will do the upgrade?
Also do you know what the price should be and how long it should take?
Thanks in advance!
Please confirm this?

Ok, so you mean that if one does the RAM upgrade one will not get more PROGRAM MEMORY?
Please confirm this, it would really be shame to spend money on the upgrade only to not recieve any additional "program memory" which I think is equaly important!
I tought that by doing the upgrade it will be equalent to a Tytn II device both in "RAM" and in "program memory"! So please confirm this!
Thanks in advance!

As I mentioned the Uni has 128 MB Flash ROM and 64 MB SDRAM. If you do a RAM upgrade you'll get 128MB SDRAM and that means you'll have MORE program memory but your storage memory remains the same at 128 MB Flash ROM
For comparison, I've taken a look at the SAMSUNG SGH i900 running WM 6.1 at its default installation and found that the FREE storage memory is about 30+ to 50+ MB. If you're the type who wants to install many programs then I think this amount is inadequate. The SONY EXPERIA X1 might be a good alternative giving 512 MB ROM and 256 MB RAM.
FI, my QTEK 9000's FREE storage memory is about 3 MB so can't do software installation even to the SD card because I'm facing the 'Storage Memory Low' error during installation of programs
Program memory is important for program running. Generally, if you do have 20 -30 MB of FREE program memory it's adequate to run most programs smoothly. However, certain programs may require more to ensure stability and smooth running.
Yes, this is the shop I send my Qtek to in Germany: http://www.srsgmbh.de/en/index1.html
He confirmed a couple of weeks ago that he's able to do the Ram upgrade on the Qtek9000. He charges 119€ for the upgrade and it would take a week excluding shipping...
Can hardly wait to get it back...!
How did you send it?

Ok I understand now, but is there a way of upgrading the storage memory as well or is it just possible to upgrade RAM?
Also does anyone know if 128 MB Ram is the limit or is it possible to upgrade even more, perhaps 256 MB?
Thanks
Info on the 128Mb Upgrade
I have do the 128Mb upgrade to my Uni. Was it worth it, well that depends, I think it was for me. You will not notice any big change in app loading speeds, but if you are running heavy weight app's like sat nav were you see lock ups or 'low resource' warnings them yes it is wroth it. It wont get you any more stroage space but it does give you more program running space.
Currently 128Mb is the max M-RAM that can be fitted to the Uni, I beleive due to ROM image limitations. The chips are also obsolite and can be hard to get hold of have a look at http://wiki.xda-developers.com/index.php?pagename=Universal_128_Shop for places that sell and upgrade. To do it yourself will require specialist equipment, so unless you know what is involved get it done for you.

Ok thanks for then info!
Have you or do you plan on testing your upgraded uni with Igo8 to see if it works properly? That is why I am considering the upgrade in the first place so it is very important for me to know if it works or not!
Thanks in advance!
I enclosed a letter in the shipment(registered mail) which explained my request, contained all details from my PDA and personal details. I also send him an e-mail with the same request...
Lets hope that all goes well!!!
Ciao!

Really? How can I get it upgraded to 256 mb?
Just think about it, 256 mb on universal, how cool is that?
If you are going to run Igo8 on your Uni then the answer to the question is YES, get the upgrade done.
Received my Qtek back today from its Ram upgrade...
86,5mb free of prog mem after reset...
Tried iGO8 on it...it used up to 65mb of prog memory but it ran very smooth...had all selected-3D building/terrain etc...
So far after 2X 30 min of usage/navigating I did not lost my 3D map...will see how it behaves when I use it for an 2.5hrs/250km trip...
That is GREAT news!

I just sold my Vibrant and purchased this G2 so far so good, when I went to back up my Rom before I attempt to over clock my phone, I seen it only said: back up 1.36gb, I read on-line that some of the newer G2's, are being shipped with 2gb internal memory vs the 4gb by mistake, I wanted to know if anyone else has had this problem, and how can I verify that 4gigs is installed vs 2gigs?.
So where is the missing 2GB?
To answer this, it is first necessary to understand a bit about how internal flash cards, such as the Sandisk card (also known as an "emmc") on the HTC Vision, store information.
Luckily, Sandisk has provided a helpful video. Pay particular attention to the discussion of SLC (single-level cell) and MLC (multi-level cell) in Chapter 5.
In an SLC configuration, a single bit is packed into each memory cell. In a multi-level cell, you can fit 2, 3, 4 or more bits in each cell. You get a lot of capacity with more bits per cell, but at the expense of speed and reliability.
In trying to figure out where the missing 2gb went, scotty2 noticed that most of the Sandisk card's block device (that is, the part with Android on it) had been partitioned within the regular "User Data Area" as an "Enhanced User Data Area".
Note that when we talk about partitioning the emmc, we're not talking about regular MBR partitions like /dev/whatever. An emmc partition is a very low-level partition of the flash. Each emmc partition constitutes a full block device, which can then be further partitioned into a bootloader, /system, /data, etc.
The card's datasheet wasn't too clear about what the "Enhanced User Data Area" did that was so different from the regular User Data Area, although one thing was clear-- once its parameters was set, you couldn't "un-set" it. To quote the datasheet, the Enhanced User Data Area "can be programmed only once during the device life-cycle (one-time programmable)."
But why was the entire Sandisk partitioned in this special "Enhanced" User Data area? No one knew.
Then tmzt found this. It's an article by Toshiba that suggests what's going on:
Those areas requiring better reliability are SLC or can be programmed as SLC. . . the Enhanced User Data Area, which may store, for example, system log files, are SLC. The User Data Area, which may store music, pictures, videos and other files is MLC. . . Each 1 bit configured as SLC results in 2 bits less of MLC. Theoretically an 8GB e-MMC device (densities are defined in MLC terms), could be configured virtually all as SLC and thus would be approximately 4GB. In most cases, it is more likely that the majority of the memory would be configured as MLC to support higher density.
You've probably figured out by now what's likely happened here. Assuming the Sandisk emmc works like Toshiba's, the 4GB flash has probably been, save for a few tiny partitions such as the radio, irreversibly configured to use SLC, rather than MLC. If so, the benefit is faster performance and perhaps greater stability (and more read/write cycles). But its capacity/density would be cut in half.
And that, my friends, may very well be where your 2GB has gone.
[edit] So To Conclude...
Assuming the above is a correct understanding of the issue, the following appears to be the case:
The HTC vision has a 4GB firmware card
It has been irreversibly partitioned to use a faster/more reliable configuration called SLC
This has resulted in a practical capacity/density of ~2GB
Update: Initial investigations from over a month ago reported that T-Mobile attributed this issue to "creative partitioning": ("I called into T-Mobile Android support and was assured this number is correct, and that I do have the full 4GB storage on-board... there's just some "creative partitioning" going on.") This may correlate with the explanation provided above.
T-Mobile lied. The phone has a physical 4 GB memory chip, but it's setup by the factory to only present 2 GB to Android. You can't change it.
I also called htc support and they assured me that it has 4gb internal memory, went to the t mobile store looked at the working demo model same deal, weird

I'd like to see a screenshot of that.
This is my G2...no 4GB, but dont really care when I am getting a 16GB SDCard. Still interesting to say the least
That has been gone over a thousand times. The phones do have 4GB chips. One XDA user even went as far as taking his G2 apart to and getting photographic evidence of said chip. the problem lies in the code. and the operating system not being able to see the other 2GBs yes it sucks. But T-Mobile is a giant corporation and they say you like the G2 you LOVE IT end of story lol. everyone is a bit peeved, me included, I would like to have the 2-3GBs free but whats done is done. Will just have to wait 2 years and see what phones are available when my next upgrade rolls around
I just got off the phone with t-mobile, they said that they will honor the 4gb stated in the specs and offered to replace my cell phone. But considering all the phones I looked at (three so far) its a lost cause cause they all say the same amount of internal memory available, so not really sure if I should accept the replacement.
Sent from my T-Mobile G2 using Tapatalk
The reps with whom you spoke know nothing about the phone. All phones have a 4gb chip but only 2gb is accessible. Read the second post in this thread, it explains everything. T-Mobile will keep sending you phones with 4gb chips, and you will only see 2gb. The only way you'll have 4gb available is if the entire chip is MLC or send you an 8gb SLC.
The stuff in the second post is from the Wiki. Read this section on "The Missing 2 GB" (same info as the second posting, but with better formatting) :
