Replacing USB port on Vibrant - Vibrant Q&A, Help & Troubleshooting

Hola,
My USB port is pooping out on one of my vibrants, and i ordered a new one, took the casing apart, and removed the motherboard, then realized that it is soldered on. SO, today i must pick up what i need, and get as much advice you people are willing to give, becayse i will be attempting this after work. Ive soldered very few things in the past, and they were much bigger than a phone. I have an iron, tho it is a fairly large one, and the guage wire i have is surley too big for this application.
My question is, on the usb port, there is 4 soldering points, and the pins at the bottom seem to just lay on their contact points, is this right?
Is there anything i need to beware of before proceeding?
I dont have anything to clean the existing solder up? Do i need one of those suction things?
What size guage wire and iron will i need?
Thanks for any help in advance!

You're going to want to make sure the foils did not stay on the motherboard. If you see any residue on the board, the new port won't get a connection.

I would maybe watch some YouTube vids and see what they do. Mobiletechvideos has one I believe. I am probably going to have to do the same thing on one of my Vibes so, I'll be following this.
I would think that you need a smaller iron with a sharper point, some flux, some patience and calm hands. Maybe some alcohol to calm you down and also to make sure the MB is cleaned completely before putting the new one on.

The power button that sticks to the side plastice piece on the motherboard was only "glued" on, do i need to buy some sort of glue to put it back in place, or does that sticky stuff never dry up?

You should be OK without any new goo. Just don't leave it laying around for two weeks before putting it back on. I swapped motherboards on my phone (ironically because of a bad USB port on my original phone), and didn't have any problems with the power button not sticking back on.
Also, from what you said in your original post, it seems you think that the port's pins just lay on the board. That is not correct, they actually need to be soldered on which is no small feat (no pun intended) due to how small and delicate they are. If you do not have a lot of experience soldering you will likely damage the port and possibly the board. I'm not trying to dissuade you from doing this if you think you're up for it, but it does take some skill. As a side note the guys at mobiltechvideos offer a repair service for $35 which seems reasonable to me.
By the way, where did you guys get the replacement port?

Broke my prime, Need help :(

First of all please don't flame me or make fun of me for what i did because i know it was stupid and i shouldn't have done it.
i took apart my prime and when i was separating the tabs i stuck the card i was using to far in and cut one of the ribbons connecting the display. so i either need to know how to completely disassemble the screen assembly and a place to buy the ribbon that i cut or i need a whole ner front assembly which i have yet to find.
I really doubt you'll find a source for the cable. I would look for someone with a "bricked" or broken Prime and try to work a mutually acceptable deal.
Bob
i took the LCD off and the cable that i ripped is actually connecter the very front part so now im just looking for the full front assembly which i still can't find anywhere
unfortunately it will be very tough to find the parts, may have to send in for non warranty RMA and it will cost you. I would estimate about $250-300 judging by what others have said but only RMA can tell you. Which sucks because they won't even begin to estimate until they have the unit in their hands.

that's the part that i need, the broken screen is part of the front assembly. but think im just gonna sell it for parts, anyone know how i could wipe al the data off it without the screen, the tablet itself still works so do you think i could connect it to my computer and wipe it somehow?

Pretty sure you should be able to wipe through ADB, though someone else would have to chime in with the correct commands and parameters. I guess I've just spoiled myself working on electronics, even if I don't have a need I keep as large a variety of cables as I can
That sucks, I'm sorry it happened lol looks brutal. Like everyone's said, it's going to be hard to find parts, but are these things really proprietary? Aside from being the wrong shape/length shouldn't OP be able to find a comparable cable? Then disassemble the LCD from the GG, replace cable, profit?
I mean, it wouldn't be the first time I've seen proprietary ribbon cables, but I figured ASUS would push something somewhat standardized since this is an internal part, unlike the charging cables people aren't going to (usually, again, sorry OP lol) lose or damage the display's ribbon cable and need a new one.
Looks proprietary to me and it looks like it might control the tough screen and display.
You are not suppose the use a card on the bottom or the top, only the sides. Once the sides are the released, the bottom should just come up, and if can be safely lifted.
Anyway, it looks more like you used a knife to open it.
Best you can do, is probably sell the screen to someone who cracked their (will require some careful disassembly), and the main unit for someone who bricked theirs.
Update: Another idea to figure the part number yourself. Then call ASUS, and say you need to that exact part, that would at least cut out their 'handling' fees.
Well. Few options like others said.
1) Buy another prime and set that one aside for parts / Wait several months
until parts start emerging forsale (LCD, bezel) etc. to fix.
2) Buy someone elses broken prime to fix yours.
3) Buy protection. Smash the crap out of it while running it over with car.
Try to claim insurance. / Buy another prime from store and replace parts
with broken and take other back. (Very shaddy.. but i am sure some would
do that on here.. lol)
4) Fix it yourself. Very difficult to buy ribbon cables that would match connections.
5) Hang on wall for Memorabilia. I use to do that with a few hard drives that
broke. lol
Repair the ribbon cable yourself. I've done it once. Will take you a whole weekend to do, but it is possible. Trust me, you will not be able to find the parts to replace your lcd.
i think im just gonna sell it, the ribbon is basically unfixable, you'd say that too if you've seen it, i took apart the LCD and i actually cut much more that 1 ribbon in the LCD so it's useless, anyone have the ADB wipe commands lol
i can access it through ADB but it won't boot into fastboot when i use the command adb reboot fastboot, it just reboots normaly, i can't wipe through adb either because i don't have access to adb shell becuase of some build.prop problem i belive.
bump, can anyone help
Hmmm. Do you have the keyboard?
Honestly, you'd have to have it or the USB adapter so you could have an input other than the touchscreen, and you'd have to cave and acquire a mHDMI cable to hook up to an HDTV. You could just sell it to someone you can trust on XDA to wipe on receipt, I know I'm not interested in other peoples' data. Suppose I'll never get ahead like Google
Sent from my Transformer Prime TF201 using XDA Premium HD via my tethered HTC Vision
i guess i'll just buy the cheapest mHDMI cable i can find, that
I'd pm Gary Key and ask if he can look up the part no.
If that route goes sour, I've fixed ribbons before with conductive ink pens and crazy glue on the bottom.
On the old style ribbons I have bought the cable and the connectors and just made new ones. I don't think you can do that now a days.
You can also look at the connector (maybe with a magnifier) and find where the wire leaves the connector on each end and possibly solder a wire on the board at that point and connect it that way.

Replace usb port?

Has anyone replaced the charging port on their rezound? Where did you get the part, and was it a simple takedown and disconnect or was there soldering involved?

It is most likely soldered to the board, which is the easy part. The hard part will be finding the MHL connector to replace it with. A quick google search turns up adapters and etc which you don't need.
I would contact http://www.mhlconsortium.org and see what they say.
The connector is a smt (surface mount) part that will require desoldering of the old part and resoldering of the new part. You will also want to be very careful to not damage the pads on the circuit board when doing this type of rework. These pads can be easily damaged if you don't know what you are doing. Without knowing the exact part number, it is had to say where to buy this part but places like http://www.digikey.com/?curr=USD sell components like this.
Thanks for the replies, I was considering picking up a pair of rezounds one with a bad screen and one with a bad charging port for cheap. They're for sale together for just over 120 on craigslist. I was going to swap the charging port but I don't think I'm up for that challenge if it is soldered to the board. Screen swap doesn't sound like a good idea to me either. I've heard too many people screwing up screen replacements with new parts let alone something used.

The screen is easy to replace. Make sure you buy some double stick tape on amazon specially designed for this purpose. I think it is 2mm wide. It's like 5 bucks and will do maybe 10 or more phones.

I would be counting on using the screen from the other phone, and from what I have seen the removal of a good screen ends up ruining it.

Seriously, are you looking for a Rezound with a bad USB? Mine charges, but hasn't been able to connect to PC since about a week after I got S-OFF. I have been looking for clean used ones so I can recover mountability.
Sent into the innertubes from my Arnova 10 G2.
I imagine that the USB port wouldn't be easy to replace, I remember trying to JTAG my Xbox360 where I had to solder 24 gauge wire to the board and it was a massive pain in the ass. The Rezound is way smaller do I'd imagine it'd be that much harder.

They make solder in a paste form that melts with a heat gun. That is what you need for small amt stuff. It makes it easy.
Get a soldering iron with the smallest tip you can find. Make sure it goes past 600 degrees F or it will not melt with just the tip.
I replace charger ports on the Nintendo DSi all day and its fairly easy. But if you don't melt the solder, and you pull too much, you could rip the pads off the board. (Which I have done many times) If you have access to a heat gun, then that is better. Use the heat gun to remove the port, but use a soldering iron to put the new one on.
All these surface mount things are placed on the board by robots and then ride through an oven, never to be touched by human hands.
The pins are quite small (Holy thread revival!)

How is your phone over 2 yrs old? The Amaze was only released in 2011.
Also, just a heads up, you shouldn't "bump" your thread within an hr of posting if you don't want to get flamed. Our forum seems to have gotten better about flaming, but there are still some hot tempered people here.
Hey my friend, im afraid you don't have any soldering skills. If so, it will be a very hard task for someone whos not used to do that since the soldering points for those phones are very fragile. I suggest you to go to a shop near you and find someone who has the skills to do such a task. Trust me its not for non experience technicians. Any way if you still want to try that at least make sure you have a very thin solder, i recommend flux also(makes your life easier) and a good desoldering braid. And the most important thing, a lot of patience... Good luck on that, but like i said, its not an easy task so you better think about taking it to a shop.

[Q] Replaced ear speaker now top half of screen has lines and hard to view

My ear speaker went out and cash short (to buy a phone full price to maintain VZ unlimited) so replaced it myself for $5. Now the screen has banding of lines on the top half and is fuzzy like half of the pixels are not working. I suspected the ribbon cable for the screen came loose so seated it firmly (didn't remove it to repair the speaker) but no luck.
Is this damage from perhaps twisting the screen in the process to get the frame off of it or typical ribbon cable issue?
Thanks for the help!

Sounds to me like the damage was caused either when you twisted the screen to get the frame off or maybe something didn't get fully tightened back down and is applying some pressure into the back of the LCD... causing this to happen.
I doubt it would be a ribbon cable issue.

Hope you get it figured out man.
Those LCDs aren't cheap for this phone.
I use an exacto knife and heat to separate adhesives, but I know not everyone has an exacto knife. Just for future reference, you can pick them up pretty much anywhere in the art section for only a few bucks. I highly recommend them when replacing parts.
Good luck finding another LCD.

Either that or buy a screen with the toolkit. I watched videos of the people with the toolkit and it helps tremendously. Plus, it's made of plastic so there is less of a chance to mess the new one up when you install it.

[Q] Rubber gasket fell out

I have had my Ultra Z since January. Zero problems, but this morning I removed my USB charger at work and a rubber gasket (see pic) fell out. Now the door does not close properly. I have the gasket and tried to work it back in but it would not go. There is a small tab and I cannot tell if it goes up (towards the screen) or down. I think I can get it back in with a toothpick or similar but want it to stay (and not lose it) and for it to re-seal the door properly. Not being able to close the USB door is a BIG deal to me.
I had been meaning to get a docking charger but bought some from China and they were crap. Guess I'll have to break down and get a real DK30.
The o-ring goes on the door.

Thanks Jammol. I'll try to figure this out. When I place it in the position it appears to belong in (now that I look closely I can see the small tab indention on the cap) but the part is so small I cannot even handle it with my big fat fingers, and don't really have a magnification station and stability setup to do it.
Big question is for the people who have had the cap break off, is there a source for the whole cap? Is it possible to install without taking the whole phone apart? Would it make sense to just throw it away and forget it was there?

I don't know what part of the world you are in but you can check these out. Couple folks have bought them:
http://www.ebay.de/itm/Original-Son...zer_Ersatzteile_Werkzeuge&hash=item2339fdd95e
I say just replaced the entire cap with one of those and call it good. Mine is experiencing the same thing, tearing off little by little. I think that is where water might be getting into my phone, but I'll be replacing the phone soon anyways. Just not sure what to get yet.
I have not gotten mine wet yet other than rain in my pocket but the lines are much better with the cap on than removed, and I'd worry about the edge material getting pulled off the rest of the phone. I appreciate the ebay refrence and will try to find a US version. So is there a way to remove the old cap without breaking it off internally and having the tab rattling around inside?
I ordered a couple of the caps and a magnetic charger off thEbay US, but seller was in Spain so it will be a while. Crappy design trying to get rubber to adhere to plastic.
Does anyone know how to safely remove the old one? Just yank? slip something very thin in to try to get the tab to ride over the notch?
Thanks,
Marc
Super glue is what bonds o-rings to other materials because of the greasy slippery surface. Mine has also come loose. Contact glue, industrial glue or anything else wont bite on that thing because of its chemical resistance that the o-ring has.
try to get a hold of a bottle of Loctite 401 meanwhile if you can't wait for the parts
http://www.ebay.com/itm/LOCTITE-401...Instant-Adhesive-Super-Glue-20g-/121407567300
to remove the old one just pull..just a bit harder ...its kind of some bend at the end of the flap that's holding the thing in place inside the device.
Apply with a pin or paper clip I take it?

At my moms work when I was young they had superglue bottles from loctite with really tiny metal pipes attached on them I wonder what loctite model that is. They could be used to do any precision work!
So it's possible to get the new one in properly once I get the old one out? From this picture it appears the new tab should slide in but I'm worried if you have to tug hard to get the old one out.

gutted!
I am so gutted i didn't see this thread before I sent my phone to Sony for warranty repair.
My gasket didn't fall off, it started to come unstuck so was hanging off and when closing the lid the gasket would unroll and the lid would open.
I sent it to Sony as I think this is there fault. The gasket should stay attached for the duration of the warranty.
They want to charge me £55 for repair, handling and shipping!! I have had my claim escalated and now they say 'upon further inspection the device is bent'!! They are willing to send it back free of charge should I not want to have it repaired...... But should I now expect the device they send back to me to bent when I know full well it was in near perfect condition when I sent to them?!?!
The bottom line is follow instructions from this thread. DO NOT send your phone to Sony.
Sony use 'authorised repair centres' so they don't even know what is going on with your device and the trust you put in Sony to give your device to a respected engineer is misplaced.
