Hi,
I can't figure out which screw-size the DELL STREAK 5" uses? I need a replacement screw.
I tried to measure the screw, it's like 4 mm in length with every mm a swirl. I tried to compare this screw to the G1-screw but these are smaller and have more swirls. There is one screw on the G1 with the same size, but it's got more swirls too.
Anyone with tips and/or advice?
PS: How should I interpret the following table?
http://www.fairburyfastener.com/torx_sizing_guide.htm
How should we read the diagram?
The table is self explanatory.
What type of head, what torx screwdriver do you need for the screws you wish to replace and what thread, so what size are the screws you wish to replace? Start with what you have that you want to replace, the table may not actually contain the right information for what you need.
If you have the screws that you want to replace, take them to a fasteners, they have the ability to measure the thread, head size/type etc and supply you with the right replacement.
Introduction:
It's been over a year since the Streak 7 has been released, long enough that Dell has stopped selling it on their website, yet noone has released a legimitate disassembly guide yet.
Around launch time there was a video made showing the device being taken apart, what makes the video completely worthless is the fact they skipped all the most important steps of actually disassembling it and fast forwards though it till when it's nearly fully taken apart.
This guide will detail out all the steps to take it apart while attempting to minimize damage to it for reassembly.
Overall difficulty: 6/10
Without a guide: 11/10
Tools required:
Hair dryer [strongly recommended]
Very small torx screwdriver
Very fine plastic shim or xacto knife
Step 1: Removing the side bumpers
The two side bumpers cover the majority of the screws. The bumpers themselves are held on by a strip of adhesive tape and are also very brittle. The most obvious method to remove them is to heat each of the bumpers with a hair dryer to weaken the adhesive on them. After heating it multiple times it should hopefully weaken enough so that a thin plastic shim or xacto knife can be forced in from the edges.
Depending on the importance of minimizing cosmetic damage, this can be the longest step.
Summerized steps:
Heat bumpers until adhesive is weakened
Shove thing instrument underneath bumpers from outside edge
Pry off bumpers lengthwise to avoid snapping them
Caution:
The area near the capacitive buttons has an exposed ribbon cable, care must be used around that as the cable can be easily sliced.
The shiny plastic bumpers are VERY brittle and can easily snap if flexed any amount. It may take many re-heatings to remove them without damage
Excessive heat applied to the screen may damage the underlying LCD, it is recommended to slowly heat the bumpers in multiple runs to reduce the chance of damage.
Step 2: Removing the screws
List of screws:
2 visible screws under left bumper
3 visible screws under right bumper
1 screw hidden underneath capacitive sensing pad
2 screws hidden underneath white pads inside side flap
The screws underneath the flap might not be possible to remove without cosmetic damage. As they are underneath the flap this may be an acceptable trade-off.
Step 3: Seperating display from body
The display try is attached to the base by plastic clips on the tray, there are 3 clips on the left side that must be detached and then the display should be able to slide slightly leftwards(?) and then opened downwards.
Caution: When detaching the display be aware of the following cables:
One above the dock connector connecting the display itself
One towards the bottom left connecting the touch sensor
One just right of the buttons connecting their sensors
Step 4: Detach display cables
The cables are standard thin ribbon cables, the main display one has a latch while the two touch ones do not(?)
Step 5: Finish detaching the display from the base
The guide will end here and not go though removing the motherboard or other components from the base tray. They are all simply held on by multiple screws.
Step 6: Reassembly
Repeat steps 1-5 in reverse order.
Food for thought:
The differences between the Wifi and 3/4g models are:
Lack of modem
Lack of PCI-E slot for modem
Lack of sim card assembly
Lack of cell modem antenna assembly
It may be possible to solder on a new PCI-E and sim card assembly to turn a Wifi into a 3/4g model. The PCI-E slot is a standardized one while the sim card bay might be custom fitted to the S7. Swapping out the modems from the EU and US submodels is as simple as removing and replacing.

Graffixnyc for donating a device to hack at with a screwdriver disassemble
FCC.gov for stock photos of the disassembeled pieces
Dell for making the Streak 7 held together ultimately by glue.
No thanks to the other teardown video for SKIPPING half of the most important steps
Shameless self-advertising:
The guide is still somewhat incomplete as when I recieved the donor S7 it was already badly damaged, also as I was working more or less blind it took even more damage in the disassembly. If I had a 2nd one to disassemble I might be able to do it with minimum damage.

WOW!! Great job getting the Streak 7 apart. I would love to see the guts of the S7 in person.
Now we just need to get you a S7 that is in read-only mode so that you can try to open it up and figure out how to reset it. I am pretty sure that the Streak 7 I sent to Dell for a reset was the same one they sent back... but I do not see any physical signs of it being opened. I still have a hunch that they had to open it because they could not fix the problem over the phone. They had to re-flash it... I am not sure if the flash was required, but it makes me wonder if they had to replace the entire motherboard or internal storage drive.
Do you see the internal storage drive? Is it soldered on, or could it easily be replaced? Also, do you see a cmos type battery that could be removed and reinserted... or a jumper to reset the bios? I am not sure if tablet motherboards are anything like desktop motherboards.
Thanks theManii
I appreciate this, I have seen the video in question - and yeah, the most important sequences for disassembly were not included.
I do have a question in relation to #1. after warming the end trim pieces were you able to use your "shim" around the majority of the perimeter, or did you just come in from the inside by the screen to work these trim pieces loose?
I look forward to the pictures, it will make me a lot more comfortable in taking on the disassembly challenge, thanks again.

Everything but the modem card is soldered onto the board and the board itself has no jumpers.

I went from the outside as I had a xacto knife and was afraid of scratching the screen, I was pretty agressive with it since it was already scratched up. If you dont go very slowly you might end up discoluring the black plastic (though it's black on black and not hugely noticible)
I used the FCC internal photos to work off of when I did it:

Thanks for the information, I will be attempting some surgery of the DS7 in the near future.
when I tried to open the links, they come up as:
You are not authorized to access this page.
not a big deal, I am mechanically inclined so I can figure out most things without too much destruction
Hmm, that's odd, perhaps they dont like direct links to it
3/4g
wifi
it's the links labeled 'internal photo' on their respective pages
Rewrote the guide, it's nearly complete except the lack of pictures highlighting the various things. Placeholders have already been placed summerizing what they will be of
best diagrams/pics on the 3G/4G linked page

These links did work.
Actually both the internal and external photo PDFs have some useful information, and it appears that the more detailed information is in the link for the 3G/4G model.
Thanks again The Manii, appreciate all the helpful information, ROMs, etc.

The FCC links work now! Thank you so much for fixing them. Those internal photos are very nice... still I would love to see one in person. I just love taking things apart to see whats inside... but I normally wait until they are dead or defective.
Looks like they use SanDisk for the internal storage... and it is indeed soldered to the board. So, I am not sure what they are doing when they "fix" Streak 7s stuck in read-only mode. Maybe they have to manually short out or complete a connection on the motherboard while re-flashing the internal storage?? Or... with the right equipment, could they actually remove the old flash drive and solder on a new one?
By the way, I like the redesigned layout for your guide. Thank you so, so much for taking the time to describe this process. I greatly appreciate it.
Did you happen to take a close look at the camera to see a S/N or make/model?
I havnt looked at any of the part numbers, I'll make a list when I make the photos to finish the guide
Unfortunately looking at the internal photos again, it looks like virtually all the major chips are underneath the two RF shields or have their own RF shield.
Pretty much the only visible chips are the touchscreen controller, possibly the sim card interface chip and one of the lcd driver chips.
I'm not willing to cut/remove the RF shields as they seem pretty secure, so I'm not gonna be able to pull part numbers off them.
What I'm left with now is a device with:
Demolished dock connector
Cut Capacitive button cable
Missing Flap
Extensive cosmetic damage
Only the cut cable was during the dissassembly though, rest was as-is.
I'm gonna take the final disassembly photos tomorrow then put the whole thing in storage.
hmmm...
I wonder if you would be interested in selling that poor streak for parts
I just bought a unit with a cracked digitizer...
finally added images to guide, I will have to go back some time later and double check it's accuracy.
It's been long enough I dont really remember the screw locations underneath the bumpers.

Is the glass and screen one piece or will the gorilla glass come apart? I cracked the glass today and the screen itself isn't damaged at all. The unit works perfectly but has cracks on the glass.
Have you heard about sources for parts?
thanks in advance,
DC
The glass and lcd arnt bonded, there's an air gap.
I dont know about getting replacement parts, beyond the scope of the guide.
can you see a maker/model of the lcd? also the battery.

Hello, looking for a broken/borked/dead HTC One to attempt a different disassembly method to try to help the One community.
It is my understanding that they are glued together, not screwed, and that the suction cup method does not work. I used to retrofit headlights that also used glues, some heat glues, some needed a solvent. I have a lot of technical skill, and i would like to try my hand at popping one apart WITHOUT destroying the case/screen. I dont care if its water damaged, cracked screen, whatever, as long as its intact.
Posted this in all HTC One sections, please PM me if you have one or know of one, i'll pay shipping to and fro (i will NOT attempt repairs, JUST non-destructive disassembly) and post the results and a video on youtube if successful, and ship the unit back disassembled if successful, and not damaged further if not successful.
Please PM if interested or if you have any heads up to exchange contact information.
Thank you,
Slade8525
iFixIt already have a teardown guide up. http://www.ifixit.com/Teardown/HTC+One+Teardown/13494/1
from that its almost impossible for anyone to dissassemble unless youre a expert in this stuff.
ive taken many tiny complicated things apart; soldered with a single strand of copper wire onto a 'dead' laptop motherboard to fix a desoldered chip, and taken apart headlights/tail lights and many other electronics dubbed 'impossible'.
its glued together; there are a hundred ways to get glue apart without high heat or fluid immersion or cutting. you can gas it in a bag to dissolve the epoxy without damaging electronics too. cheaply and safely.

Ifixit screwed up royally. The way they did it was completely incorrect. Do not use that as a guide for anything other than what not to do.
Heat gun, proper plastic pry tools, and small screwdriver with a t5 bit should the tools needed. And of course the proper disassembly steps in the right order. Ifixit missed that last part and already admitted they screwed up.

I am not getting what you wrote...
When you take off red back cover from a phone you'll see printed circuit board (pcb) or motherboard if you like. All chips, processors and ICs are soldered to it. In the bottom left corner there is a very small tablet battery soldered to the board (or at least this thing looks like battery). I'm trying to find out what it is, and is it possible to replace it, mine fell of.

If you are talking about the little rectangle thing at the bottom left that has a clear view to it, thats the vibrator.
I guess nobody have seen pcb of their phone.
It'll be as was said, the vibrator, I've had mine in pieces and there's no battery onboard or after reflashing or battery removal the internal clocks would not reset.
Schematics don't show an internal battery either although they're not HTC's in any case. Failing soldering it back on and it's still not working leave as is or remove it, probably make battery last longer

Check here: http://forum.xda-developers.com/showthread.php?t=2272612
It does look like a motherboard battery like you'd find on a pc motherboard, normally this would keep the time and date and bios settings.

If you're insisting it's a battery (I wonder why you lose all settings for WDOG, TCK etc within a couple of mins tops???) It's more than likely just a capacitor set for slow discharge whilst you put the actual battery back in, or it's just the vibrator ... No battery... It's not on the BOM either

Hi, some time ago when i was dissasembling my Nexus 6 due to a camera replacement, i accidentally broke an smd component below the camera that is part of the screen well it only detached one pin ftom the two it has so i suited it in his place again and attached back the yellow transparent tape it has, i proceeded to reassemble the phone and all went good except when i low the brightness to certain point it starts to show Green lines and distortion but at a normal ir not so low brightness there Is no problem, Also i noticed an high amperage consumption and consequently a low battery duration i suppose it happens due to the broken component and want your advice if i should weld it again, it is very small and Is surrounded by many components as the same i broke, should i use heat gun? Or a soldering iron ? Tin welding or liquid welding, or i just should heat the welding the component has and set it again un his place? There Is a photo of What im talking about (the photo Is from a broken screen i have but it shows the components)
http ://i.imgurcom/h4TemYN. png
Just add the point after imgur and delete the spaces to see the image, im not available to put links Yet.
Lots of questions to ask here, so I'm going to just get to it.
1. What is the wattage rating of your soldering iron?
2. Is your soldering iron a pencil type or gun type?
3. How small is the tip?
4. Did you apply any extra solder in attempting your repair?
The wattage of the soldering iron and its type are critically important. Too much heat and you could destroy the component. Also, the damage here could be to the board itself and not the component. When one side lifted from the board it could have pulled up the solder pad the component was sitting on, breaking the trace underneath. What I'd need to see, prior to you doing anything else, is a picture of the actual board you worked on.
My advice? I would get a new screen. The fact of the matter is that you shouldn't have taken a soldering iron to the component as you could easily have burned the board and burned out the component. In such a confined area you could also have accidentally created a solder bridge, which could also cause the issues you're seeing. What you should have used was a heat gun set to 300 degrees celsius. Hold the heat gun one inch above the surface and turn it on, holding it steady for one minute. So long as no traces were broken in the initial mishap, this would allow the solder to liquify and restore the connection between component and board.*
*A heat gun is what I used to repair my Dell Inspiron 15, by applying steady heat to the GPU for a minute. This caused the solder balls making the connection to liquify and restore the connection with the motherboard. Two years later and the laptop still works.
It s an easy job with the right equipment ,and being a technician . Only trouble I can think off is to find the same component but since you have a broken screen it should be easy. I think if you have no experience you can seriously ruin your display. Bring it disassembled to a technician with the component to remove and solder back from the broken display . It's an easy job and I wouldn't charge more than 10€ to resolder it from the broken one to the working one. Elsewhere if you want to do it by yourself you need an hot air rework station and a good flux to recover the component from the ko display , and then a fine tip to solder it back ( a good flux is your friend ) . Don't use hot hair to mount the component to the new display, you can screw the flex cable, it's really delicate
@Axel85: I don't agree that it's necessary to be a technician to replace a surface mount component. The OP can do the job if he has a low-wattage soldering iron or a variable wattage model. I do agree that flux is a good idea however. I honestly wish I had some when I was repairing my laptop, but I also got lucky. The heat gun I thought would have been better for the initial repair, because I thought this might have been an actual board on the underside of the display that the ribbon cables connected to. Thus the soldering iron was the right choice.
The problem here is that he didn't post a picture of his work, so we can't see what's been done to the board. For all we know the pad lifted off the board, which broke the trace. He could have burned the board by using a high-wattage soldering iron. He could have destroyed the component with the soldering iron. If he used additional solder he could have accidentally bridged the connection. There are simply too many unknowns here to present an informed opinion.

Yes we need pictures... It's not a board, it's fully a flat, so hot hair could ruin the flex even if you move it flat to a dashboard, you can't even imagine how easy is to break those flex. More than this with hot air and amoled displays you have to be really careful, those types off display are delicate too. For the fact that it could be able to solder back the component , if he can is ok, but to do a perfect job you must have experience ,the matrix of components on the flex is very tight . It's better to bring it to a technician than try to do something you can't do... It's 10€ Vs a screen replacement of 180. If he has experience , better for him, for me would be an easy job.
You should also consider that the use of the display without the component could ruin. Something else on the motherboard
@Axel85: Just to clarify, I'm not saying he shouldn't bring it to a tech. Just that it isn't necessary to be a tech to do such a repair. I agree that he'd be much better off taking it to a tech, though I think it's too late and the damage has already been done.

Yes I understand but I can tell you its harder than you think, you must have a good skills with soldering iron to resolder this component inside this matrix of others.
We need to know more about him and get damaged area pictures to evaluate an answer

1. 60 watts the thin soldering iron, 140 watts the gun one , i have other pencil soldering iron of 30 watts
2. I have both
3. I don't have the specifications but is very thin
4. No i just suited the component in his place and put back the yellow tape
5.- The board is all right i also confirmed it (The component i broke is part of the LCD)
6.- I've already posted a link to the image because i can't post links or images yet, there is again : http ://i.imgur.com/h4TemYN. png (just copy and paste in the search bar and delete the blank spaces in the link to see the image)
7.- All right then i will try it
Thank you so much for your advice :good:
@BRMX7: Read the rest of the thread before doing anything.
1. You should be using no more than 30 watts on small electronics. 60 watts for your pencil iron is too hot and will have likely fried the component. I hope you didn't try using the gun on this, which leads to my second question.
2. Which one did you use to make this repair? I hope it wasn't the gun, because you may have done far more damage than you can see.
3. Post a picture.
4. Good. That eliminates the possibility of a solder bridge. Though there may still be damage you can't see, especially to the component itself.
5. How can you confirm it based solely on sight? On the rare occasions where I needed to get up close to the work, I had both a 16x and 20x jeweler's loupe handy (most recently when I was repairing my car remote).
6. According to your post, the image you posted is not of the screen you worked on, but a second screen that was already broken. @Axel85 and I both want to see a picture of the screen you worked on. If what you posted is the screen you worked on, make that clear.

1. Okay i will use it in 30 watts it is a variable welding station
2.I haven't done anything first i asked for advice before doing any repairment on it.
3. i did it (i will post one of the damaged one)( I didn't posted one of the damaged one because i'm using it right now and i haven't my tools at the hand to dissasembly it and take the picture) looks exactly the same than the damaged one because the indicated component in the image is in the same place but just with the right pin detached .
4. I will have care
5-6. I confirmed it using a variable power supply and a multimeter doing various proceedures to know what was the problem, testing if the power consumption was problem of any component or the screen, also checked it with a flir thermal camera of a friend and it was all right in the board.

The best way than is to recover the component from the old broken display flex and solder it back in place . If you ripped off the solder pad you can search where it goes with the tester, you just need to expose a little point of the solder pad way ,and then make a bridge
