[Q] [Help] Need to delete data on water damaged SGS9000

So basicly, I dropped my galaxy s 9000 in a drainwater hole next to my house and had to get it out with my shovel. I did so and obviously because it was raining, it got water damaged and also has dirt inside of it.
Since it was in there for around and hour with the battery still in while I tried to get it, Its pretty hopeless to try to fix it or send it to repair, particularly because I'm upgrading to SGS3 in a month or two.
I want to sell it on ebay for spare parts use but I want to first whipe all data off the phone, because it includes many documents like my paypal account history and emails on gmail. The problem is, if I try turning it on, the usual white text "Galaxy S GT-I9000" text shows up and in several seconds turns off. Even if I try booting into recovery mode, I just dont have enough time to hit erase all data.
So is there any way to whipe all the data off of it other than microwaving/purging it?
Thanks

Bump please help guys

I suggest you to put it in straight sunlight with battery taken out
hit thanks if I helped

I opened it and its completely corroded already and it would cost far greater than the phones currently worth to fix.
Anyway, as I asked, is there any way to erase all data off of it if it doesn't turn on for more than 5 seconds?

Identify and desolder Flash IC (or IC-s if there are multiple).
No problem if these are TSSOP-s (they usually are) - this can be done with soldering station and soldering braid.
If these are BGA-s then use heat gun and something to pick up the (very hot) IC.
Update: just thought that if you don't have time/tools to make it then there are 2 options:
1) just disassemble the phone, purge motherboard, sell what is left.
2) Find some mobile phone / computer / electronics repair shop where they can remove and destroy these Flash IC-s with you seeing it.

Before I do that though, is there actually any way I can possibly delete all data without destroying the hardware (If it isn't yet destroyed by the waterdamage ofcourse)

I know no way to destroy data in Flash memory without damaging other phone components or without disassembling if device itself is not operational.
Suggestion at the moment is:
* Wait for more feedback from forum members. Clearly there's a lot more experienced members than i here
* Meanwhile try to get phone as dry as possible - it may happen that it boots for longer time e.g. tomorrow

Indeed. Stick it in a bag of rice until you get a better idea

I will try doing this. I took the phone to my friend who used to repair mobile phones, and he kindly wiped the components with WD-40 on a toothbrush for free. He says that theres hardly any chance it'll work but it may eventually allow me to boot up for longer than 10 seconds which will be enough time to flash the memory.

[Q] new digitizer, still not working!

hey guys, so i have the LG Optimus 2X, P990-HN, i'm with Fido (doubt it matters) anyway, there was a large crack in my screen, and i just dealt with it for a long time, but eventually the glass FELL OUT, the rest of it worked, but i couldn't leave it, so i ordered a new Digitizer from DealExtreme.com and it was about $50 CAD, reviews tell me it worked, googled it nobody else had complaints, so i doubt it's a fake or anything, all the way from singapore, i put it in and i can see everything clearly through it, beautiful, but zero response from the touch screen. none at all in any area, what could it be? also, if i take the screen out to re-seat it do i need to apply heat and completely remove it, and if so will that make it garbage and need a new one? will the heat kill it? i'm quite upset because it costed 50 bucks and took a long time to get here, and i finally put it in and it doesn't work, all help appreciated!

Have you tried the service center ? One probable way to check if the new one really works is to connect the old one back and see if touch works.. You might have accidentally pulled out some other connection .. just my guess

if i take off thte new screen with a hair dryer, will that ruin the screen though?

Not sure about that . Is the new screen stuck on to the device like a sticker ? I recall seeing some YouTube videos on Optimus 2x surgery

The digitizer , screen and the glass are usually a single unit .. yes any one of them is worn out , it can be replaced ... but u have to find d place where it s done ..

yes i ordered a digitizer though, replace it and it didnt work, what the hell could it be i just dont understand, and i can do it myself but i don't know the problem

I have done this twice with OK success. It is important to connect all electronics correctly - check YouTube for guides. But even if you did all correct be digitiser might be defect. Either you being it to service centre or redo digitiser install. Maybe, you can check before closing the phone, and if not working correctly check with your old digitiser. Heating and reheating should be no problem (although nothing is without risk). Good luck.

hey, thanks for helping me out. i think the digitizer MUST be defective, i took it apart and put the old SHATTERED one in, and it works FINE, aside from you know... being shattered. then i plugged the other NEW one in, and no response from the touchscreen. the ribbon wire looks to be fine, the connection to the logic board was fine, everything was hooked up right (or the other one wouldn't have worked right?) so if i cant SEE anything wrong with a digitizer, what could even be wrong with it, it MUST be defective, but what can really be defective about a digitizer? what can go wrong on something with so little to break...?

Don't know what is wrong, but it must have been defect before you got it. Try to return it to the seller/shop as soon as possible and get your money back.

Hello fellow Droiders

I have a problem with my phone . A technical one .
in portrait mode the touchscreen is not responsive at all but in landscape everything is just fine.
ofc , i tried other roms , wipped OS , reinstalled it , but it always happens .
it usually work for a day or two (in portrait , but it works like hell , extremely laggy , it double-triple taps when i touch the screen , it does not unlock and i need to take out the battery in order to use the phone again)
Now i am just using the phone with the qwerty out and that is an inconvenient sometimes ..
What could the problem be ( i must mention that i dropped the phone on the floor severel to a hundred times ) , i might think there is a problem with the phones sensor , maybe something at the cables which connect the front side of the phone with the back one or maybe the touchscreen ( but i dont think it is its fault )
some advices b4 im take it to a mobile phone service ?
No advices such as "contact verizon bla bla bla"i am from romania .

Your ribbon cable may have a tear in it. Sorry.

Honestly you would be best taking it apart yourself to see what part it is.

Should just be a standard Torx screwdriver set.

Yes, but to replace the digitizer on the Droid3 there is one especially small torx driver required that most kits do not include. I think it is a T3, maybe a T2.5, but in any case I had to look hard to find one online.
Repairing the Droid3 at this level is quite difficult, even with the correct tools, especially if there has been any wear or corrosion of those tiny torx screw heads. They can easily be ruined rather than backing out.
Best left to professionals maybe, and then you have to wonder if it is worth the time and trouble for a Droid3 ?

[Q] Two SCH-I800s, one dead, one damaged, question about a fix.

So I've got two SCH-I800s
One's working fine (battery's a little low)but has some cracks in the screen.
The other is in perfect condition but dead (internal storage problem, won't boot, SD booting not working either).
Question is: can I somehow bring the good parts of the two together? Can I take the internals from one and put them in the other? I'd rather avoid replacing the screen because of the methods I've seen for doing so being pretty complicated. I am good with taking devices apart and have been doing so for some time, I just wonder if there's an easy way to do this?
Thanks!!

Just google how to replace the screen and digitizer. U think fixya has a youtube video ob how. This will show you how to take them apart. Then just switch the motherboards and put it back together. Just go in through the back cover.

I've seen that video. But what he does is what I was avoiding. I was hoping it wouldn't involve removing the screen from the tablet because then I have to get new adhesive, the tool to take the screen off, etc etc. I was hoping somebody might now if it's possible to just get the insides out and put them in the non broken screen tab I have. Does that make sense?
Is it possible that if I remove the logic board and leave the screen and it's board intact I can just take the actual tabley logic board to the other tablet and it wil run fine? They are both identical SCH-I800s.

Thats what I was talking about. Go in thu the back. Just stop when you get the motherboard out. No need to remove the digitizer and screen. Then put in the other board. Hook up all the connectors, screws etc. The only thing is the meid numbers wont match.

I know that with my Android phones, I always read that if you swapped parts the software can have trouble communicating with the components and it can cause problems. I will never be selling or sending back these tablets for warranty or anything. Do you think I have anything to worry about? Any possible complications that can arise?

I dont think you should have a problem. I swapped the digitizer with no problem. The other stuff- on/off, volume, etc are just controls. Should have no effect. For the meid, just take the one off the back of the tab. Make sure you copy it and keep it safe. Just to be sure l later.

Hardware MOD to improve GPS and eliminate lags on ZE550KL

Hello, after many many attempts to make my phone work i think i've found the final solution.
My GPS was barely working, during car navigation It worked intermittently, and so it was completely useless.
In the last try, just before to put my phone into the trash bin, i've tried to cover the contacts of the back cover, where the antennas are, with the graphite of a simple pencil. I've also gently raised all the metal tabs to improve contact.
It sounds crazy, but after that the gps works very well even in indoor.
Since i don't know which contacts are for GPS i've done it on all the contacts, and now even WIFI improved.
Other experiment was to install a 0.5mm thermal pad between what i think it might be the cpu and the backplate of the lcd to dissipate the heat, you can see the area in the attached picture, after that the phone is very reactive and heats a lot less.
I wanted to share this experience with whom wants to try before smashing the phone on the wall and i hope your results will be similar to mine

I have (had) the same issue. Here is my bug report on the official ASUS forums > www.asus.com/zentalk/forum.php?mod=viewthread&tid=102873
A friend of mine bought the same ASUS Zenfone Laser (I recommend it to him) and he did not experienced this issue. Look at my phone on the left hand side and his phone on the right.
HOT start:
View attachment 3909336
COLD start:
View attachment 3909337
I've send it to the official service center in my country (ROMANIA - Euro Service Center) and they said they've "replaced the conductive tape" and that's it. That did not fixed the GPS issue.
I went for a night run, to test the GPS on my freshly serviced ASUS Zenfone 2 Laser... Below are the results:
In the same conditions, same day, same hour, a Samsung S4 mini was doing great!! (proof below)

Too bad you did not post this earlier as I've send my phone to the service yet again and they did nothing in 21 days.
Given this situation, I've asked them for a "won't fix paper" and they wrote one for me.
Now, I have to buy another phone... :crying:
Seeing this fix from you makes me wonder... why the guys from the service did not try such a thing? Seems pretty simple to me...
Also, If I knew that your solution was that simple to implement, I would have tried it myself instead of send it yet again to the service (as the guys from the service did not "sealed" the phone after they've send it back to me the first time)
Since I don't have a smartphone any more, I've being looking around at the current offers, from other phone makers and ASUS Zenfone 2 still seems like the ideal phone (taking into consideration that I don't want to spend more than 270 dollars on a phone).
I'm wondering if I should give ASUS another try, another phone from the same Zenfone 2 family...

Thermal pad
Can you tell me what is the thermal pad material. Its silicon or other type ?

Not sure. They didn't fixed anything, so I just got my money back for that phone. Too bad... it was quite good otherwise.
