Question about 128 MB in Magician

Does anybody know what type and perhaps where I can buy the memory module so I can change it myself.

I do not think you would want to change it yourself, it will require some really advanced soldering skills due to the way memory chips are surface mounted.
(A nice article can be found here: http://www.howardforums.com/showthread.php?s=&threadid=549700&highlight=+bengalboy++128)
My sugesstion is to ship it to www.ppctechs.com. They're reliable, fast, and a worth everyone of those $199.

thanks for some nice info
Im a electronics skilled worker and have access to an advanced solder bench so I think I will manage it.
But I still wonder what type of memory module it uses and where I can order them.

Not a clue. Since I guess PPCTECHS will not tell you I guess, the only thing you can do is open the device and examine it

Mini is using 2pcs of Infineon 16Mx16 SDRAM, BGA package. What you need is 2 pcs of 32Mx16 devices to mount on the mini. Speed of the chip is a PC133, CL3....guess in this case, the CAS is not really important.

thank you for the info.
Ill try to find a place to get them.

Please post any info you get. I'm also interested in doing it myself.

Any news ?

I wonder if some of the modules I found on this page can be used
http://www.infineon.com/cgi/ecrm.dll/ecrm/scripts/prod_ov.jsp?oid=58787

Desoldering BGA from SODIMMs requires you to reball the BGA...you need the rite tools to reball them first b4 remounting them, its best this way...if not...it will not be good..

[Q] Is there DVB-H support in Desire Z

Hi
I am considering the Desire Z and was interested if one will be able to watch DVB-H TV on it. I know that the MSM7230 chipset supports it, but it does not appear anywhere in the DZ specs.
I am assuming that Qualcomm supports it, but HTC have not licensed this module? Could there be any custom ROMs in the future that might add the necessary drivers?

Bump !!!
This would be ******* awesome, in theory, if it's there, you can enable it, but, you will need a hack, and some kind of driver. Just guessing, because till now, nobody have hack nothing more than a FM Radio or a Bluetooth module, but, let the developers own one first, then, when 2 months have pass, we have root, CM 6 or 7, audio hack, OC, and some other super user tricks, then, just then, start thinking seriously about this topic.
Remember, first, we need root.

It is very unlikely anything like this happen. Yes, the chip maybe supports it - but without the supporting equipment on the board, without the antenna, it's useless. So you can stop thinking about it.

MSM7230 supports it and apart the surely missing antenna you don't even know if the required pins are soldered on the board.
IMHO this will never happen and it's obvious that I can be wrong, but I can say that I'm pretty sure of what I'm saying...

Are you both sure that the antena is missing ? Because till we didn't know that by fact, we can't say that will never happen.

An antenna would cost money to include, why include a part for a feature that isn't available? That would just be wasting money.

If the support was there, why would HTC not advertise it in the product specs ?

For marketing reasons The next phone will use the same chipset, but will have "more features". As far as I remember P3600 owners one morning woke up with an in-built GPS that they never bought
I realize however that in this case we have likely both hardware & software limitations that might be hard to overcome.
Similar to the Diamond/Touch Pro case where the chipset supports hardware graphic acceleration (Qtv), but it was never licensed for these devices and the available drivers were pretty limited as far as I remember.

need to learn hardware hacking

what tools do i need to learn how to hack hardware, specifically, the antenna on the galaxy s3?

The only real way you can learn about hardware hacking is hands on experience. Go out and get a og Droid or something to mess with. You will learn what you can do. Read anything you can get your hands on! Get a rotary tool and learn to use it on scrap plastic or metal. Learn the hardware of phones and how it all works together and what it does. Ask questions, answer question (make friends here on xda). For the antenna thing, on most devices the antenna is not to be messed with as manufacturers already have it in the ideal location and configuration. Like in the HTC rezound all the antennas are in the back cover.
Hope I helped

While some devices have an antenna jack for factory test, it is often inadvisable for users to use this antenna.
If you are looking into signal strength improvement, it is strongly recommended to use a close-proximity coupled antenna combined with an amplifier - look at Wilson Electronics' cradle+amp solutions as an example.
While it might be possible to add an antenna jack to many devices that replaces the built-in antenna - don't try this unless you have a spare sacrificial device or two, as such a modification will be irreversible!

Entropy512 is right
Just prepare to buy a new device!

Replacing Flash Memory Chip

Hi Everybody,
so i was looking at the teardown for our little baby, when i came across this:
Toshiba THGBM5G6A2JBAIR 8GB Flash
So i went online and do a little search. It turns out that Toshiba builds other sizes of this particular chip.
Looking at the specsheet, it seems that every single spec is the same (can't post the link yet)
So i was wondering if we can replace this damn chip (since i'm stuck with an 8gb version of the Nex 4 (Yeah..since they don't sell in Italy...i had to find a compromise) I know it would take a lot of soldering works, but the real problem is: How to install the OS and stuff?
So i'm planning to ger one of this chips, or a broken phone with one of this (from 16 to idk) and try to do some research, in order to get if i can do this substitution.
So..anyone tryed this before that can help me out with some advices?
Thanks everyone and for the mods...if this is not the right place to post this, i'm sorry...:angel::angel::angel:
p.s.
Sorry for my bad English

Don't attempt to replace the chip with a soldering iron. You need someone with a dedicated SMT rework station that can handle BGA devices. (this chip is a VFBGA according to the datasheet).
Even then, it may not boot at the end of it... Be prepared to have a bricked phone... On the other hand, if it works, you may be able to make a buisness out of selling 32GB Nexus 7's until Google/LG makes them....

Basically, it's not something an end user could do.

Ok, so since is a BGA device, reballing and reflowing should do the trick.
I know that is something that an end user shouldn't do...but give it a try should be nice...of course i would not go straight for the replacement on the n4, i will start with something else before.

Installing it is one thing, it's getting the important stuff on there that is the problem.
It's not a case of just fastboot flash, since there are more partitions than that.
Plus you need fastboot to be there in the first place, JTAG would probably cover that, but the rest? God knows.

Yeah..that's my problem afterall...i mean..put the chip on that is kinda fine..i mean i do this on notebooks so i'm used to reballing and stuff.
But the OS thing is going to drive me mad...meh..need to figure out how to do that!

Just don't do it. You're gonna regret it. Laptops is one thing but a cellular device is another. Chips are way smaller and complicated. It's not as easy as you may think.
But it's your phone, you can do whatever you like to it.

This is retarded. You realize those connectors are so small it requires machines worth millions of dollars to attach and connect. Might as well use some Elmer's glue or a hot glue gun if you're gonna do it yourself, or hey maybe even some ear wax, you'll get the same result.

Ok, nevermind.
I'll do some tests with my machine and some old crappy phone...u never know what is going to happen..lol
Tnx anyway guys!!

Everyone else here is an unambitious ass

Dude you shouldn't let people detour you, soldering chips is not that hard and the size of the chip doesn't really make a difference for BGA most of these guys probably have never soldered a BGA chip in their life so how would they know how hard it is. I would suggest that you practice on some old pcs or an old game system that you dont care about. the hard part about this would be getting your hands on the new chip (and weather or not it is pre-balled because re-balling is a *****), from what I can tell toshiba only will sell the chip in a minimum quantity of 5 chips per order so if all goes well you may be able to charge people to upgrade their nexus 4s.
People are to scared now-a-days to get their hands dirty and take risks to get what they want and I commend anyone willing to put in the time, learn a new skill, and get what they want even though no one will just give it to them.
I hope you decide to do this anyway.
PS. The bootloader/recovery should be a separate memory module all together and should still exist when the chip is replaced, so if I had to guess i would say that you could just flash a new rom assuming your bootloder is unlocked and the chip comes pre-formatted.

Everything is held on the eMMC chip, nothing is separate.

evice suggestions for demonstration of JTAG benefits

I tried to get some help in the Q&A section, but it appears this is more technical/hardware seeking question than just generic "which phone" thread.
I have been suggested Samsung Galaxy Spica/i5700 by boofman (thank you), but the device is cost prohibitive.
I would very much appreciate anyone's suggestion.
I am planning a presentation to demonstrate the benefits of JTAG for data recovery on embedded systems. The audience has approx. 12th grade education, but higher than average computer understanding.
I have most of the equipment already, including a uLINK2, Bus Blaster, and Raspberry Pi for the UART-to-USB, and OpenOCD for the software.
What I am missing is the simplest cell phone (or other inexpensive embedded device) to make the demonstration.
I would like to connect to the device and list the devices on the JTAG chain, and recover the data from them.
What cell phone brand and model would work well for this presentation?
I would need to know the JTAG points, have access to the data sheets of the onboard chips, and since it is out of my own pocket, I hope to get the phones on eBay for a low price.
Any suggestions are welcome.

Check out gsm-forum, under the hardware repair section.
Googling for jtag pins and your phone model number usually works for me. I'd assume you might have to wait a little bit for brand new devices, unless you feel like scoping the pins to find out which is which or hope their labeled.

These individuals are not kids. :fingers-crossed:
Excellent resource at the other site. Thanks!
But, I think I do not think I made myself clear regarding what I am looking for:crying:. I am not looking for info on how to JTAG a specific phone.
I am looking for 3 or 4 of the same model of cell phone that
I can pick up on eBay or similar for reasonable price (<$30/phone),
the JTAG TAP is known on the motherboard, and
it would be a bonus if the JTAG command set was known (besides the basic requirement).
This would allow me to make test run on one of the phones, then demonstrate the use of JTAG on the others.
The Samsung Galaxy Spica is a good phone, but I do not have the budget at $100+/phone. I need to find something cheaper. It does not need to be fancy telephone, or even smart phone - just have sufficient JTAG documentation.

If anyone has any ideas on what to use for this demo, I am still in need of a good idea.

You can look into any of the older HTC phones for this. I think that would be your best bet. I've done plenty of hardware repair, disassembling, reassambling, flashing, etc... on Android, & non-Android phones, & from my experience, the older HTC phones are the best. Specifically, concentrate on the GSM ones, such as for T-Mobile. Look into HTC myTouch 3G Slide (awesome little thing) , HTC G2 (one of the best keyboard phones ever), myTouch 4g, myTouch 4G Slide (overheating, self-destructing piece of crap), even the HD2 & the HD7. These are all devices that you can get for around $30 or so with a cracked, but still working digitizer, or some other kind of problem. Screens & other parts for them are very cheap as well.
Also, these are all known to RIFF Box. Look it up. You can do JTAG repair with these, & RIFF Box have all the JTAG ports labeled & documented. They might have some of the documentation right on their site, but I'm not totally sure. Anyway, check it out & see. I think this will be exactly what you're looking for.

Excellent! Thank you very much.
I have looked at looked at many commercial products, including RIFF Box. I narrowed the selections down the RIFF and ORT, but they are both very expensive for demonstration purposes.
I do love the fact that one can buy "jigs", "clips" or "adapters" (names change depending on vendors) which removes the soldering requirements for some of the phones. Except, these are still very expensive. :cyclops:
Again, thanks. I will look into these.

I'd go with Galaxy S 1 as it's really cool to work on and relatively well documented and demonstration on such stuff always looks well. But if you want something low-budget. I've seen JTAG pads on Nokia E50'ish stuff. Or try with some Samsung S3000's, these are pretty cheap. But I don't know how's JTAG there.

as @3ndymion218 told you , search old HTc .. also some Samsung that I think cheap could help too .
Samsung F480 , F490 , U700 , U900 etc ... some news Corby model also .. I think cheap .
I could help if you were near to me . I have 3 phones that I could offer you ...

Thank you for the further info.
Definitely will try to track down the HTC and Nokia information.
Samsung is a bit pricy as you said, but maybe down the road.
Again, thank you all!
