Ok here goes nothing. A friend of mine had her home broken into. Long short of it they stole her tablet. Since it was locked and they could not get into it the completely destroyed it. There is no hope of any repair. The reason she needs the data is her daughters pictures and video is on there before she passed away. I did manage to salvage out the main board of the unit. It was mostly in tact with a few chips knocked off due to the impacts. The emmc chip on the other hand is in untouched condition. The board is even cracked in a few spots. The model on the board looks like SM-T217S. The Emmc chip itself has the markings of Samsung 401, KLMAG2GEAC B002, HMKP009V. I called around to a few data recovery places and they want 300 plus to do it. Is there any other way than desoldering the chip from the board and wiring it up to a micro sd card adapter to recover any files?
Pay the recovery service. You wouldn't have any of the support circuitry needed for the memory chip to work and would probably permanently lose the data. They are professionals and know exactly what to do in this situation., you don't.

hi, I didnt find anything about swapping the nand chip from one phone to another so i was wondering if this is possible since my girlfriends phone is broken and contains over 700 pic and videos and she has no backups. im pretty sure the mobo is fried as the charger light will no longer come on and phone will never attempt to boot. there is a guy on craigslist with the same phone( droid incredibe) with cracked screen for cheap. i could swap out parts and make one good phone but would like to swap nand as well as the screen. does anyone know if this is possible without having to flash the nand chip or lose any data? or any other suggestions would be greatly appreciated.
1) It would be helpful to describe what is broken and/or how it happened. Did it malfunction during a backup, bootloop, etc.
(not assuming anything but just saying)
2) If it's a battery issue have you tried using another battery to at least transfer files to a computer?
3) Have you tried using another usb cable in the event your cable gave out?
That would be VERY difficult, if not impossible. That component is not socketed in like you'd expect to see in a computer. Everything is soldered to the board and the chips typically use a ball grid array connector. Installing it on another system board would be nigh impossible without the soldering paste used in manufacturing. I wish I had a better answer for you. Even if I tried to do it with things around the house, I think I'd destroy the chip and the working system board in the process. You'd need a fairly precise oven.
Sorry snoop, tried all that. Different battery, wire etc. I have 2 of them so I did swap stuff around. And I should have said what happened to it. It got stepped on and bent a little. The mobo got cracked.
Loonatic, thank you. That is some good information as I didn't know how it was attached. I am pretty good at fixing things but that sounds difficult.
Thank you both for trying to help or provide some insight.
The memory chip is Pretty much garbage if I can't get it off of the motherboard so I guess it wouldn't be a loss if I broke it. I might give it a shot

It's cool, ironically enough once I read loonatik's response I realized this was way over my head.
I need some help all, a year ago I bought an evo with a cracked screen and somehow when I took apart the evo I chipped a small micro chip that is on the board. I think its a chip. anyways. in the picture you will see i've showed that chip with a big Yellow arrow. After putting on the new screen the phone just boots to the lock screen and is not responsive to touch. After 10 seconds or so it just reboots and does this over and over until I pull the battery. Does anyone know what that little micro chip does? Could it be replaced? is it the reason the phone is not responding to touch and boot loops? Any help is greatly appreciated.
So nobody here knows if this chip is why my evo is in a boot loop after it turns on?
even if you could find that chip, it's very unlikely you or anyone else would actually be able to replace it.
If you managed to damage that chip during a screen replacement, you have essentially broken the chain of data through the board. Your best bet would be to find a broken EVO on ebay or something to get the chip from a board. However like the previous poster said. Good luck replacing it.
I saw a few threads showing that repair of the eMMC chip for the desire is possible. I would like to know if it would be possible to do the same with the epic touch. The replacement eMMC chip's for the desire are usually regular brand name chips that have been pre-programmed. Would it also be possible to copy the information from another working chip onto a brand new one and install that onto the epic touch? Thank you
Usually the issue with replacing the chips is getting them removed and put back on. The mounting processes they use today and component size/packaging don't tend to lead to easy replacement w/o specialized equipment.
Thanks for the reply. I guess I could sell it for parts then. I have a hard bricked e4gt that I used as a wifi device, but to even pay for a repair, I need to have sprint service, so I just have paperweight.
Possible yes. Probable no. I don't know for a fact but I'm guessing this phone was assembled by a robot that was programmed to work with and solder component level surface mount technology. If you did it by hand, you would need specialized tools that would cost MANY times more than the cost of three phone, just to replace a chip. Many electronic devices these days are disposable. That meaning to repair the hardware would cost more money than to just buy a new one or for a few dollars more.

I would assume they actually used a reflow oven and bga chips with the balls of solder already on them. Yeah a robot likely placed the chip.
Now I just need to find someone selling a motherboard. I can just use any motherboard as long as it's clean esn right? Finding one is gonna be really tough.
Hi all,
the wife's HOX died suddenly, won't turn on at all, wont recoginse being plugged in into either the wall or the PC, no lights, nothing.
Unfortunately she has taken a number of pictures of our 5 month year old son on it, which obviously we would like to have back!
I'm competent with taking the phone apart and putting it back togther, however what I want to know is how the Samsung Flash chip is connected to the mainboard.
I can see black glue around the outside of it, but I am unsure if the underlying pins are also soldered down.
My intention was to razor blade the glue away and then buy a knackered (but working) HOX and transfer the chips over.
Obviously I wouldnt be able to do this if the chip is soldered down. I have monkey hands when it comes to soldering things.
Is anyone able to offer any insight?
I've had a google and read the datasheet for the specific chip, but it says nothing about how it is connected.
Thanks in advance.

I really can't see this being successful, sorry. I'm fairly sure the chip is soldered down, and the chances of damaging the chip are very, very high if you want to try and get it off.
If the phone didn't come into contact with water a JTAG recovery might be possible. It may not get the phone working again but it could get your data back. Alternatively companies like DriveSavers have an excellent reputation for getting data off flash chips, but it'll cost you in the region of $400 - $1400 (I got a quote a month or so back, when I thought my HOX was finished.)
I really wouldn't recommend trying to remove the chip though. You could do irreparable damage to the chip, which would render it completely unreadable.

Try first change the battery to see if the phone will start again it is the cheap way and most secure
de4life - thanks, I've had a quote for data recovery from Kroll. They want £95+ to look at it and provide a list of what can be recovered and then between £195 and £395 for actually recovering it for me. Far too expensive!
As for JTAG, there's been no water damage whatsoever; I've had a quick Google and it says this is more for Routers. How could I do it to my phone? Im not fussed about getting the phone working again, just want the contents of the flash storage back.
Thant - alas, the was the first thing I tried. New battery has made no difference. Which is annoying as her old Desire Z showed the same symptoms, we bought a new battery and its works again. She's currently using that until we decide what to do.

First thing's first, if you do go down the data recovery route try to avoid companies that charge any type of analysis fee. Kroll are a well known company but I've not heard much good things about them. I went through an extensive search of companies when I thought I'd killed my HOX and found DriveSavers were the best in terms of reputation, and they don't charge a fee to look at the phone. They are very expensive though, perhaps more so than Kroll, and you have to send the phone to the States which is daunting and costly in of itself (I assume from your £ quotation that you're UK based?).
It's good that there's no water damage. It's difficult to say what can cause the motherboard to suddenly stop working like that, but it's unlikely there has been a serious short circuit that could have affected the memory chip. Have you tried dissembling the phone completely and putting it back together? It may sound ridiculous to even try it, but when one of my older phones suddenly died I managed to get it working by taking it apart and then just putting it back together again. There are a lot of connections within the HOX motherboard framework that could easily have come loose. You might already have done this, but just a thought.
In terms of JTAG, it can be done on mobile phone motherboards with the right equipment. It's usually used for soft bricked phones to reset the software back to its original form if it's been corrupted, but I have seen cases where hard bricked phones were brought back to life using this method, including the HOX. It's not really something you can do at home (not cheaply, anyway) but there are companies that provide this service. One of the more popular services is here: http://mobiletechvideos.mybigcommerce.com/htc-one-x-jtag-brick-repair/ - I believe they post on here from time to time as well. Again, based in the States, but significantly cheaper than data recovery and as far as I've heard very professional. I don't know of any mobile phone JTAG services in the UK, though they probably do exist.
Keep in mind the data chip on your phone is likely fine. Even if the motherboard has stopped working, the memory chip itself is unlikely to be affected and will still contain all of your data - albeit in a scrambled form. If you send it out to companies then they can potentially damage the chip beyond repair, if you go down the route of sending the phone out to repair/data recovery companies I would urge extreme caution. If it's still on the chip the data itself isn't going anywhere. Take your time and make sure you're sending your phone to the right people, because one false move and your data is gone for good.
Hello to anyone reading this,
This crack in the board happened after it went through the clothes washer, and it was gf's phone so i feel really horrible about it :crying:.
Anyways i have yet to even find out what this piece of the board is named. It's cracked in two places on the vertical part of the board that leads down
to where the usb connector is located (everything else appears looks ok just these two cracked pieces). I'm just looking for any help at all, hoping
someone might be able to offer any help at all, or if it's even possible to salvage. I have an uncle that is got a good amount of experience in
soldering/electrical stuff and can handle the soldering/fixing since im still a bit of a noob, but he was unsure about how to go about it since it would
require some very small wires to fix the connection traces, so if anyone can offer any advice or instruction on mending i would greatly appreciate and
can send some BTC for your help. I attached 2 images, and can supply more if you need more detail.
So far the only thing i can think of is to get a broken board and remove the part i need at the easiest location it could be re-attached... no clue if that easier area exists though..
Why not just bring the phone to some phone repair shop (or a samsung specialized one), if available in your region. They should be able to repair it (if the price is ok with you), or be able to sell you the part you need (order it).
**It looks like even some chip is chopped... at the very least, probably too much water damage on them. You don't want to do this repair by yourself (or you uncle)... there are cases of phone components getting too hot and on fire if there are faulty wires/connectors.
****Definitely a new board is required.

Yeah seems like a new board might be the only solution..
can anyone tell me what exactly would be compatible? This was a verizon note 2 sch-i605 gt-n7100 rev 1.0.
Thanks all
