mini usb disloged ? Imate will replace it under warranty!

Hey people
my mini USB became dislodged a while back, I pursued the problem - I was sworn at, I was lied to, I was made to go through useless paperwork their website chat programs are down most of the time and even when u do connect u have to endure a person who cant even grasp the basics of English.
I don’t like it when innocent people get hurt by corporate greed, They are still trying the same tune with everyone all over the world, Despite in my case when they replaced it. If they recognise it in one case they should recognise all cases!
Attached is a receipt with the fault, the replacement under warranty, my old imei and my new imei. It even has my personal information so hopefully should stand up in most courts around the world if need be.
I hope this helps
btw- I gave this a new topic status so it would turn up in most topic searches easily.

Please look if you Adore the Universal

This is exactly what i need to do some projects but, that's a lot to drop on a hobby. Maybe someone who can part them out will buy them.

keep an eye out on the sale, if not sold please contact me thru ebay:good:

that's good
that's so good, but what if i need only one "even if with broken screen" , is it possible ?
PS. I only need the main board, please help

please wait until the ebay ad has expired. If not sold i will do separate sales, I unfortunatly have no spare good mainboards, but working universal will not be expensive One with small usb problem wil be cheaper ofcourse

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.

You'd be surprised what kids know these days.

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!

Anyone still recalls the TPT1 (circa 2012)?

I'm happy to report that mine is in its sixth year and still going strong on original battery. But it's showing its age based on the Android version. Still charge it and update the apps, maybe it'll become a classic someday.:laugh:

Unfortunately mine doesn't charge reliably at all by USB anymore, so I can't really use it. I was actually here again to see if someone had found the docks for cheap and I found out some people were making their own adapters for the dock port.
Do you happen to be the same eldata that uploaded these photos?
If so, do you still have the schematics or BOM for your adapater? It seems all the info from RootzWiki and the r-888 links on the XDA wiki died some time ago, and the Wayback machine is missing the most useful parts.
