how to disassemble o2 atom xda

I somehow managed to get water in my screen so now the tapping function doesnt work. I dont know what else to do. I am currently in Beijing and bought it second hand so I'm not sure if the warranty is still in place and if so how abouts to get it to a retailer. The only thing I want to do now is try to open it up and see if I can try to clean up the moisture and water since its still there. I tried opening it but there are only two screws at the bottom back side of the unit that are available to me to get to. I'm not sure how to go about and disassembling the whole thing. The pda is really important to me since I use it as a chinese dictionary. I dont know what else to do. Any help would be appreciated. Bye

Firstly, you can check if it is still under warranty by registering it on O2 website, you will need the original receipt to claim warranty (and moisture damage is not covered by warranty). Secondly, if you want to fix it yourself and I dare say its too late as the battery would need to be removed immediately as moisture enters the device, even if you manage to get an LCD (roughly US$250)and you're able to fit it there's a posibility the main board and components are damaged too. However, I have repaired to some degree with many tedious hours of careful cleaning with pure Ethanol. My advice to you is send it to O2 for repair and do not put the battery into device!

can you tell me how to take it apart? everything seems to be working fine, just that certain areas on the screen i can't tap. I know there are two screws at the bottom back side of the unit where it says void. But other than that I dont know what else to do to get the unit open.

the housing for the camera must be removed, very carefully, under that cover are two more screws.

Thanks zecoj, however I have worked it out for myself and posted in this forum (what I believe is) the crucial stage of disassembly process. I cant believe how nicely designed the Atom is, for all its downfalls I now have new hope in my Atom....

Can you pl provide the details of the disassembly... Pics would be appreciated... Thanks in advance...

i think the water is in the screen protector..if your unit have a screen protector..i already see and replace my atom screen bcoz i break my lcd and it's all sealed by a static tape..noway to enter a water inside..can you take a picture of your unit that can see the water..maybe you screen is damage..you have to replace it..or lets think not..ill be waiting for your pics..

Touchscreen related problems

http://www.youtube.com/watch?v=uQ7csMbeQDA
The device screen doesn't react on pressings after running for some time, mostly running some more demanding application, in my case as seen in the video clip, a 3d game. The center-left part of the screen just won't answer to my touches, to get it more clear I've made a clip.
P.S.
The phone was bought in Romania (Eastern Europe), had been in service one time, seems all they've done is to resoft the phone.

Are you having a leather case or something that wraps over the side and front of the Leo? I can't see clearly but it seems so.

Have you tried hard resetting the phone? backup all your data and hard reset.

I did that (even in my video if you watch it); Updated to the latest firmware available on htc, same stuff.
P.S.
this issue appears mostly when I press the reject (power) button, so it's smth. with lower right corner...

I don't see why there's a discussion or even a post about this. The phone is obviously faulty. You say yourself that it's not a software issue so you need to take it up with your supplier. If they've already had it once and sent it back in the same state then you need to tell them that, not us!
They got to replace it. It's unusable in that state and no amount of software or tweaking will make the screen suddenly work for you.

i think the easies way is to send it for repair,
if i were you, i would do my best to identify the problem cause and be able to reproduce it whenever i want so i can go there to HTC and prove it.

Thank you for your reply, too bad the servicemen don't share this opinion, and the thing is more complicated due to the fact that I live in other country and have to ask some ppl to get the device delivered, and due to the random nature of the problem, it is really complicated;
the meaning of this thread was to identify, maybe someone has met such things, and knows what exactly causes the fault, so I don't receive the device the second time with "resoft" written on the service ticket...

BRICKED - even the resistor trick doesn't work !

Hi all !
I'm writing here because i'm facing a problem with a "SAMSUNG Galaxy 3" // aka // "Samsung GT-I5800" ...
Someone gave it to me because it seems to have bricked the phone during a flash process.
I really don't know if it is electricaly dead or just if the BOOT part of the flash is corrupted.
What i tried :
{VOLUME DOWN} + {HOME} + {POWER}
{VOLUME UP} + {HOME} + {POWER}
301kOhms resistor trick on pins 4/5
I'm now wondering if the phone is dead or not ...
As the phone is quite new (!!!) i would have liked to test some things, like JTAG on the port reserved to it on the motherboard.
What i don't want is buying some kind of external JTAG devices like ORT or RIFF.
By the way, i have skills in programming ; electronics ; computers.
I have an arduino that could be used for interfacing the JTAG port to the PC serial port.
I'm not very sure about the JTAG pinout on the motherboard.
I found some informations at RIFF website about the JTAG PINOUT :
If someone can tell me how to use this JTAG port to inject the bootloader inside the flash, it would be very cool.
Thanks !

stop all those experiments. You will destroy your phone. Go to a Samsung Service Centre. It could help.

I can destroy the phone because i don't care about it, and, moreover, no one will cry if it burns/explodes/anything else.
I can do wathever i want on it.
By the way, by saying "whatever" i mean getting it back on its feet.
So i want to do it by myself.
I'm sure this is not much hard way to do it as there is already a JTAG port which can permits to talk directly with the CPU.
I found something from QUALCOMM : QPST (Qualcomm Product Support Tools) which is compatible QSC6270 CPU (inside the GT-I5800).
With that it is possible to flash firmware/bootloader etc directly inside the device !

The phone is certainly dead. Bootloaders gone.
You have to buy a riffbox to do this as the bootloader repair files is contained by it. And I don t think you can get those anywhere else. Buy a Riffbox. Read the manual by which you can find out the pinout using voltage readings. You ll also get support on there wesite with the pinout. Once you get the pinout major problem is done.
Cool stuff this you are doing.

basicaly this is possible and can bring a brick of any form back to life...
i think u can achieve this! i also see some pins at the back of the phone
under the battery.....
i strongly advise you to read the FULL thread and search some more!!
if u achieve this we may even get an ubrickable mode!
u may need solderinng skills...
i dont know much but i will try to help!

In fact, i don't even know how to use JTAG port neither how to talk with the CPU by this port.
But, some people can manage to do it, i will ... !
I just need some people to help me with this, and after i will be able to release a software that can run on an arduino (for compliance with a lot of phone models) and, firstly, a flash program under windows that will use the COM port of the arduino to talk to the JTAG connected device.

That will be awesome. For a start, you need to find out the voltages required so that you can access the ROM(PROM) of the bootloader to rebuild it. Will also need the varous voltages for the various pin outs. And I have absolutely no idea about that. Maybe someone with previous expierence and can help you. I doubt there are any in our G3 forum though. :/:/

Ok, i know that the voltages seems to be based on +2.8V but someone managed to get it working fine on +3.3V (Arduino is able to deliver +3.3V, by the way, we can use a small component that allows conversion from one side +5V to another +3.3V (plugged by Vcc on the +3.3V of the arduino).
I must give it a try.
But, right now, i'm absolutely lost on JTAG way to talk on the lines.
Moreover, i just don't even know what can i do to flash something inside the CPU/FLASH (like bootloader only which will permit the phone to boots and enter download mode).
In fact, what i'm willing to do is :
Build a Serial RS232 (PC side) to JTAG (PHONE side) interface that permits to onl flash the BOOTLOADER part of the FLASH of the DEAD PHONE.
Perhaps it could be used directly on ODIN but i doubt that the flash software would talk the same way to the CPU/FLASH on a standard USB FLASH that it would talk directly connected thru the JTAG port on the PHONE MOTHERBOARD.

AdamOutler and his frnd did something similar like this for hummingbird devices
We talked and he said if he can get a diagram of g3 with the processor area enlarged would heli him determine - or you can just look it yourself - look at the pics he posted and compare
And yes they made a program to talk to the device and allow access to download mode - even on a fully bricked device - just needs a small mod - i hope you can do it - search for his thread for more info
The program is called Hummingbird Intercept BootLoader
I think it should work on our phones coz currently it works on s3c devices (samsung proccys only) so it must work with small mods on s5p
Good luck!

ok if this is the case then I take my post back. I thought the one who gave you that wants it to be revived at any cost. If you can experiment anything with that then what you are doing is awesome. If you are able to inject a Bootloader you can make it to boot also.
But its risky, Still if you take chance you could bring up something new. By the way how this happend? Was the phone disconnected in download mode?

In fact, i don't know at all what happened to the phone.
I think it must have been injected by some kind of corrupted image.
As i don't know what happened directly to the phone, i know the guy who did the trick.
... And i know that he's a really mess up for electronics ... so i think he must has been using ODIN but he had used wrong files conducting the phone to be unbootable, and moreover : BOOTLOADER FAILED !!!
Everytime i flash a phone, the only thing i let on its place is the bootloader because if something happens during flash process : PROBLEM
And even if during flash process there is no problem, who knows if the bootloader injected is good ? perhaps it could be a dictionary page ?
I'm actually waiting for a part to come in my postbox.
This part is this thing : http://www.ort-jtag.com/shop.php?ID=32
With this, i will be able to connect myself (or anything other part of my body ) to the JTAG connector of the phone without destructing it by soldering like an old'parkinson guy !
But, i'm running into some kind of complexity with the flashing process because it seems that "AdamOutler and his friends" already worked on a similar case (different phone model // different CPU) and encountered an encryption problem.
I need the datasheet (detailed version) of the SAMSUNG Galaxy 3/Apollo CPU's for knowing if i'm running into some kind of problems ...
I hope that for uploading a bootloader there is no RSA keys needed.
If it is the case, then, i must say right now : it's dead.
Breaking RSA encryption is not the good way.
There are other ways (like bypassing code-signature) but i have to tell you guys that i'm not really expert in these techniques !
Will be back in a few days when i will receive the JTAG connector in my postbox...

You could have a look to s3c6410's Application Notes, the two chips seems to be "similar".

Sorry for my strict answer, but, i'm not part of people that asks dumb questions without searching first on forums/google.
So yes i tried it.
... And, as i'm really paranoid, i tried it another time this morning
But ... no luck, i've got a big black brick like new ... but "hard-bricked".
So i will try to make my way to the JTAG connector and deal with it.
The JTAG connector is coming by post right now.
What i have to prepare by the way should be the code for my arduino to be some kind of an "interface" between a serial port available on my PC and the JTAG connector of the CPU of the SAMSUNG Galaxy 3 (Apollo).
Scheme should be :
[PC]:USB.port <-> RS232:[ARDUINO]:JTAG.protocol <-> [SAMSUNG GALAXY 3]:CPU.jtag
What i don't know right know is : what the hell the communication looks like on the JTAG pins ?
What i understood right now is that there is 7 pins :
XjTRSTn - INPUT - TAP Controller Reset
XjTMS - INPUT - TAP Controller Mode Select
XjTCK - INPUT - TAP Controller Clock
XjRTCK - OUTPUT - TAP Controller Returned Clock
XjTDI - INPUT - TAP Controller Data Input
XjTDO - OUTPUT - TAP Controller Data Output
XjDBGSEL - INPUT - JTAG selection. 1: Peripherals JTAG, 0: ARM1176JZF-S Core JTAG
All of these works based on "IO Power" of VDDSYS.
Voltage must be : -0.5v < VDDSYS < 4.6v
The voltage which has to be used must be +3.3v.
On my Arduino; i can use some little circuit to BUFFER and ADAPT serial communication voltage from +5v to +3.3v. This shouldn't be a problem to do it.
I need someone to help me with communicating on a JTAG port/interface.
It seems that JTAG connectors are differents from one ARM version to another.
Moreover, i couldn't find any information to know the bits order, the clock, the mode, the returning clock, etc ...
I tried to have a look at the Linksys WRT54G/GS on which there was a great JTAG community for bricked devices.
Problem is that this kind of JTAG port is not standard.
No luck on this device !
But i found some precious information inside this PDF : http://www.jtagtest.com/downloads/viatap.pdf on page 7/15.
It talks about JTAG Waveforms ... which is what i'm exactly looking for !
Knowing this i can do some code on my arduino which will be able to create the waveform, establish the HIGH and LOW states on different pins.
For now, as i said, i have a lot of projects to work on, and, i must wait for the JTAG connector to come inside my postbox !
See you guys

[Q] Recovering data from a toasted A500

So the tablet had a bit of an accident where the power button broke off on the inside. I went to go solder the piece back on and accidentally burnt off one of the contacts on the board so now the power button won't work. Is there anyway I can recover the data from the internal SD card?

Take a look at this. There are many other ways to make the repair, but these are nice, and you should be able to resolder once applied.
U.S.

U.K.
http://www.ebay.com/itm/Conductive-...985?pt=LH_DefaultDomain_3&hash=item5ae72b24b9

I'll have to see if I can find that here. Is there any way to recover the data without having to do repairs?

The information, is stored on flash rom, which are probably perm attached to the MainBoard as with most things these days. Nothing that can be removed or popped into a card reader.
Not like in a PC, or an older device that used an eeprom. Of course you would have to have an eeprom reader to access it. But usually these were programmed at base level.
You should probably just send it in for repair. Chances are, they won't bother to look what's on your tab. Then again, if repair is in the US, Department of Homeland Security dictates all electronic repair facilities copy and send all information from all electronic devices turned in for service. There's always that chance.
50/50 chance they will send your tab back with all info.

It's not worth it, There is also damage to both cameras and the sd card slot. I was able to get a 16gb A501 online for $225, I just wanted some of the data that I had stored on the old one. I'll try and get the repair tool to fix it but I won't spend much money to repair it.

Well you can send the broken one to me and Ill be glad to mess with it, I need an extra one to tear apart , if you dont want it , dont throw it out!

Haha. I plan on attempting to repair this one. I want those files on there and IF I get it working, the wife can use it for her business. I checked the price on ebay just for that board piece, its half the cost of a new tablet.

no I wish I did MD , it would be fun playing with them, all I have right now is a HPJornada 680 , paid a buck for it and it works , only problem was it used a a port similiar to a USB (but it isnt usb) ,so I soldered a new port to it (usb) and it works (sort of) gotta figure out how to add the usb to CE , other than that for a touch screen built in the 90's it aint bad ,but CE is real limited!

[Q] S4 i9500 buying tips

I'm planning to buy a used S4 through a local website that offers a space for people to display ads for their phones (something like Swappa), but the problem is that :
- I have seen many fake products which looked exactly the same and even have TouchWiz on JB. What's more confusing is that most of these products have a printed valid IMEI number.
- used phones might have hidden problems with their sensors, or hardware in general even if they are genuine.
Questions:
01- I though I might compare the valid printed IMEI with the one I get when dialing *#06#, but I'm not sure if that number can be faked as well, can it?
02- Is there a systemic way of checking the sensors, cam, microphone, wifi etc by an app or something similar?
03- I think a benchmark tool like Antutu's can help to see the exact specs and compare them to the original ones. Can some of you take a screenshot of the exact specs as they appear in Antutut Benchmark or Android System Info.
04- How to know if a genuine S4 has been flashed before if it has an unrooted stock rom at the moment of checking?
05- Any advice on what to look for when examining a used S4?
PS: I will have physical access to the phone before buying.

The Device Info tab of the same Antutu results you sent. It's on the top right; just click and send a screen.
And the same goes with Android System Info; install the app and send me a screen of the System tab. It's the second tab from the left.

have fun

Here are some codes that access various functions of the phone.
Most useful:
*#0*# - this will give you access to a test mode, where you can try various functions (cameras, speaker, display, sensors)
*#06# - to compare the IMEI displayed by the software with the one on the phone

well,you can check if your phone is genuine or not simply by using this app
https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo
if your phone is fake samsung it won't detect at all
second use this app to detect your hardware info and sensor
https://play.google.com/store/apps/details?id=com.inkwired.droidinfo
i always have this 2 apk stored in my sdcard so i can install and check the phone if i'm buying 2nd hand phone
P.S:i've been using these method since i've been scammed once for buying fake samsung galaxy s4 because it has fake antutu app

Conclusion
I searched a lot and here's a systematic test.
*#06# (dial it on the phone itself)
to get the IMEI number and compare it to the one printed on the package and the warranty certificate if any is present.
Droid Hardware Info and Phone INFO ★Samsung★ (apps from Google Play)
use these two apps to check the hardware specs (like processor, number of cores, GPU, ram, etc)
Diagnostic Menu *#0*# (again dial the number on the phone itself)
and test all the items
Connect to a laptop to check if it's read properly.
Use a Micro SD to check if it's read properly and try to copy a couple of small files to it.
volume down – power – and home to get to download mode it should say
CURRENT BINARY: Samsung Official
if Custom appears somewhere in current binary or system status, the phone has been flashed before.
Check the battery look and weight and connect charger and see percentage/min.
NOTE: There's a faulty battery batch whose serial starts with BD1 you can find more info in this thread
Check the hand and headset buttons and their buttons. And rotate the 3.5 mm jack while playing some music to see if there's a problem with its socket appearing as distortion in sound.
