I've screwed up the multi-jacks on two separate motherboards now by using the HK sync cable from eBay. It just puts too much stress on the jack. Today I found a real sync cable at a flea market but I seem to have permanently fried the current motherboard because no matter how carefully I reattach it, I get a constant red light from the R/O/G led.
So I need a T-Mobile motherboard (or any motherboard that will work with a Cingular US connection, if there is one). Does anyone in the US have one to sell me? I have a spare battery/back cover component that should work fine or a Nokia NGage to trade or can pay cash.
Help me out here, don't know if I can wait for another broken screen unit to turn up on eBay at a reasonable price. Thanks!
Just post this.

If the Nokia NGage would work with T-Mobile and the teenage I know
wanted it then that could be a deal.
Unfortunately, my cat chewed off my 40-pin usb charging cable and I'm going nuts atm... so has anyone found anywhere that might sell a cable like this? I looked pretty much all the online places and they're none existence, perhaps if i take it to local phone shops, will they be able to solder it up?

To be honest i do not think they sell those separately yet
My first guess is to call Asus directly, and tell them what happened and they might send you a new one or let you buy one over the phone if you feel comfortable doing that
Or even contact them on Facebook they actually monitor that very well
As for the cable splice, i am not sure of any phone shops that would do that, at least in my area, maybe a electronics repair shop would be better, probably charge you an arm and a leg though

No extra cable with the dock...unless I got shorted one.
So I spent over an hour talking on the phone with them this morning, apparently, they don't even have a part number for the cable, I even had to convince them that this doesn't sell in the local shops first. Now they're saying there'll be a "special" team which will contact me within 24 hours to solve the problem.

Asus were brilliant for us when my Mum had a problem with her Eee PC a couple of years back - screen failed, got a brand new one within a week. Couldn't argue at all!
It does seem vary by product, hopefully they'll contact me soon.

Don't tell them your cat chewed it. You're better off saying it's defective and the store won't take it back and demand a replacement. When they get yours back they'll charge you for the cat-chewed cable and everyones happy.
Telling them it was your fault will not get anything done quickly, because they don't have to give you a new one. Try it the other way around and at least you can get a working cable and they'll charge the money it would have cost to sell it to you.
Hope it all works out.

My bad, i thought the dock came with a cable because that would be the most obvious thing to include , guess i was wrong lol
I called again later and on the third time was able to get a RMA for it, sent it to the service center right afterwards so hopefully I can get a phone call sometimes next week about the payment. But from what they said, it seems like they don't have these things on stock for replacement, kinda sucks since I'll be out of country in a week and half.
I've never repaired a cable before, so I haven't a clue what I'm talking about, but if the wires inside of the cable are color coded, I bet with a pair of wire strippers and a little solder and electrical tape, you might be able to do the job yourself.

I peaked through the opening of the cable, the wires were extremely small where I could not see the inner metal wires within the cables and they seem like un-strippable (so thin that I'm afraid to break it with typical wire stripper), also there're metal wires on the outside wrapping the inner cables which are also damaged. Just gonna give up and let them send me a new one.
ASUS suggested website
BTW, one of the reps were telling me to go to this website and check if they have the cables in stock http://www.asusparts.eu/index.php
I think this will be the first place to have them if any charging/replacement kits would be available. However, currently there're nothing related to the TF.

Now bad is it? If the 40 pin end is intact I could fix it.

I found out that they listed them over last weekend, also sent them an email asking when the cables will be available.
They replied:
transformer is now delayed to mid-June.
Sorry to have to give you the bad news...
But im not sure if they're talking about the tablet or cables, gonna ask them again and see what they reply.
Sorry you are having to cope with the problem. It's got to be very frustrating. I'm waiting for my TF to arrive from Amazon. It will be at least a month from order to delivery, but that's got to be less frustrating than having it in your hands, and not being able to use it.
I'm sure the USB connection for charging uses only 3 or 4 wires, so it might be relatively easy to temporarily wire it, but at best, it would be highly vulnerable to breakage. I think you made the right choice to RMA it back and get a new one.
I have a quick question for anyone that already has a charging cable. Approximately how long is it? I looked at the picture in the link, with it wrapped up, but it doesn't look very long. Anything less than 6' will be less than perfect for me, although I could use a USB extension cable if necessary.
My power adapter died on me today!! I can charge with usb from my PC and now im using an old iphoneac adapter to charge with. It is really slow though, gained 1% in about 10 minutes....

Find a universal USB charger for an iPad. It should charge the TF while powered off, or at least with the screen off. It will take longer to charge, of course, but it should do the job.
Thread for hardware mods
POSTING INTERNAL tf101 pictures
like 3g dongle ? internal sd cards? ssd?
removing the battery for 2 HDD 500go?
finding sd cards hubs? usb to sata cables?
? there is a place in the tablet for a 3g dongle?
there are 2 screws under the upper rubbers and the dock open easy
there is a lot of spaces avaible
My MIFI might actually fit in there, all I would need to do is supply it power somehow.
I'm no hardware engineer though, but if thats possible it would save you from the driver issues with a 3g dongle.
I wonder if it would be possible to check which pins from the adapter connect to USB - so we can make DIY USB adapter for those without a dock.
hmm adding an hdd would be very interesting, sata won't be very hard, powersupply will be.
Sent from my O2x with CM7
This is what I was looking for, looking to do some mods to the dock.
Thanks Markolino72.
Internally mount and wire a 32gb memory stick to the USB port so you get a 32gb hard drive added whenever you dock It might even have enough room for a portable USB hub so you don't lose use of the external usb port?
does anybody think it will be easy to make a DIY dock fix for those with battery draining issues like me?
It seems like it would be relatively easy - just make a switch to either connect or disconnect the cords coming from the docking point.
Or even better, maybe if you put the correct microcontroller in there you can have it switch the pins to floating, if it senses that there is no tablet connected (not sure about the details though)...

Have you seen the post in the General forum (2nd page now I think)? Posted by Asus_USA themselves, if you prove the 6 steps that your dock has the issue you can get a new one! I really do hope that I can get mine exchanged, waiting on a reply from my local service center..
Regards.
In regards to the hardware mods, that really looks amazing. Would love to put in my mifi there as well, attach it via USB to charge = your own 3g model Maybe a little modding you could get the mifi to power on only when the dock is connected (remove the battery of the mifi?) so that when it powers on it'll power on the mifi as well. Only a few thoughts.

it's a good thought but the mifi I have (novatel 2200) wont work without the battery, for some reason if the battery is bad or removed you cannot run usb, it must be the way they have the power run through the battery or charging. Not sure if all are like this or not.

I talked to the Asus service rep about it. They currently won't give you a new one since they have a hardware upgrade to fix it. If you wanted a new one you needed to do before they solved the problem. I'm waiting on the upgrade part to be delivered for for mine. Should in a few days.
A switch should theoretically work. The guy at the service center said the replace something that goes into the hinge of the dock. Looking at the teardown pics, you can see a wire goes into each side of the hinge, so I think they replace the wires and maybe make a new connection somewhere on the dock.
Surprising how much wasted space there seems to be in the dock -- it's nowhere near as tightly packaged as the tablet itself. Looks like Asus can optimize the size or fit some more features in future versions, if they want...
Let me see if I am thinking correctly...Your saying using something like mifi installed via USB wires (will it be always on?) then connect via WiFi on your transformer? So basically your putting the mifi in a case that can never be opened without a screwdriver? I guess one would always have access for your other devices as well as long as the TF is in the vicinity.
P.S. I think I think this is a good idea, not decided though. I like to think of it in a real world application.
there is another post with a guy putting in an SSD, but it bulges at the keyboard. A 32g SD card would be nice.

Well I ended up calling them. I would have to ship the dock to "someone" in the US, have them ship it to the repair center, fix it, ship it back and then ask that "someone" to ship it back to me... sooo, I'm basically screwed... I ended up with a nice 150US paperweight (not even considering the horrible light bleed on the transformer).

Yeah, actually, I hadn't realized that but it does say it clearly on the product warranty page:
"Brazil and South American countries don’t support global service"
http://support.asus.com/warranty.aspx?SLanguage=en&p=20&s=16&m=Eee Pad Transformer TF101
took mine apart also and there is quite a bit of room.
i plan on putting a 128gb usb flash drive inside the dock and soldering onto the usb connections once i get all the bits in.
Any bigger pictures? Are the screws under the rubber feet?
just two screws under the rubber feet near the hinge then it just pulls apart from the top
had to take mine apart as the spring/clip mechanism for the sd card wouldnt lock the card in.
now the card is stuck in with no nails haha a simple fix.
This is good news. I hacked a Crystal HD decoder card (pcie), USB wifi dongle, a logitech nano receiver, and a 4 port micro usb hub (from a touch screen setup) into a Dell mini 9 and there was absolutely no room compared to this.
They even have covers for the USB ports, so if you remove a header and solder wires up you just have to hot glue / epoxy that cover from the back and you are money. Looks clean and stock.
I have an old 64 GB thumbdrive that might find a new home. Maybe a 1.8" usb HDD would fit in there with the battery, without the battery who knows.
Hi,
I recently replaced my usb flex cable, and my signal has been very weak ever since. I have tried loosening the screws and removing the small wire (aerial) and putting it back on, but my signal is still very very poor. Has anyone else had this problem after disassembly?
It may not be relevant but i'll mention it anyway. The screwdriver I used had a slight magnetic charge, just enough to pick up the screws. Could this have damaged something?
I'm on O2 UK and have tried other O2 aims, but to no avail. I have also tried my sim in other phones and signal improves greatly. I noticed it instantly after reassembling the phone so whatever has changed, happened during the course of replacing the usb flex cable.
Any help would be greatly appreciated, thanks
Does anyone have any ideas on what could be causing the signal to be so consistently weak? Would it be worth replacing the wire antenna?
I have taken this apart and put it back together countless times, trying to see if there was a loose connection etc, but have had no luck so far. I even put a bit of folded tinfoil between the usb flex cable and the contact under the battery to try and help the connection. I've completely run out of ideas.

I think you just disrupt the antenna. Sending it to a customer service repairs should be a good choice

As I bought it from Ebay IE, I have no warranty, so will have to pay to have it repaired. i was hoping to have a go myself, however there doesn't seem to be an awful lot of information out there regarding this problem. I have found a replacement antenna for £3 so I might try that, however I'm not sure that is the problem as the antenna looks in good condition and was only disconnected briefly.
Edit: Oh and thanks for the reply

Thanks, but it wasn't an app that caused the change, so I am reluctant to use an app to try and work around a proper fix.
Having read awful reviews for my local repair shop, I have just purchased a replacement antenna to try and repair it myself. It cost £3.00 so I'll fit it as soon as it arrives. If that doesn't work I will HAVE to take it to be repaired :-(

You are a life saver! I was about to trash my S2. I got it used with usb and sound problems for about 130 euro. Swapped parts but had crappy signal. The signal was bad before to which I also bought new antenna. Network signal never worked properly since acquiring the phone 2 weeks ago. Swapping modems never helped.
I still have the old USB board and it looks like exactly like the one I replaced. Thinking of the same thing you just did. Now my question to you, why didn't you remove the other SMD to make the boards match? I might try removing both on the old to compare signal levels.
Your info should be stickied!
Thanks again!
Tried that Trick but now I dont have any more signal at all...nowhere!
Hi,
I had a problem with the micro-usb port/charger in my galaxy s2. It was what others have already described (constantly charging/not charging, voltage too high messages, etc). So I decided to buy a spare part for the charger, and replace it .
The first time I turned it on, The charger problem was completely solved, but I noticed the signal was gone. I realized I forgot to connect the antenna. So I opened it again and connected it. The antenna is a HF cable which connects to one end to the main board, and to the other end to the spare part I bought.
After reconnecting the cable I saw an improvement, but the signal is still much worse that before replacing it for the first time.
I bought the part here (German language):
[] IShallNotPostLinksAsANewUset []
Could it be this replacement part?? Might be a capacity adjustment problem? I don't know how are usuallry phone antennas designed. I don't know either if this part plays an important role for the antenna (it is anyway connected to the cable).
What can it be? What would you do to recover antenna sensitivity? (I do not have the broken part, it is already gone )
Best regards

Hi, after having had the same problems with charging, I also changed the micro-USB flex circuit/cable. I bought it in the UK from e-cell (on ebay) ... and same as you, I am not able to get 3G anymore, only G! Charging is solved, 3G is gone!
I do have the old part still ... will put it back on and see what happens.
UPDATE:
OK, I put the original part back in ... and 3G/H was immediately back. I can also see that the network strength is the same as with the replacement part (so it doesn't seem to be a defective antenna cable or so), but now it picks up UMTS and HSPA+, while the replacement part only caught GPRS. So what this means is that the replacement part is not the same as the original ... probably the same problem you have.
At the same time there was no miracle and the original part is still no charging unfortunately ...
I had ordered 2 other replacement parts in HongKong which should arrive in a couple of weeks ... will try those when they arrive, and hopefully at least one of them will solve the charging AND the 3G issue!
UPDATE 2:
While driving around with the phone with the replacement part, sometimes I do get E/3G/H+ signals, so it appears that the part is able to handle these ... but maybe only when the signal is very strong? Or maybe there are different types of E/3G/H+ signals?
Hi,
Experiencing the exact same behaviour, the signal is really bad (never above 3 bars). I'm going to open the phone tomorrow to make sure I left the antenna cable properly connected, but judging from what I'm seeing here, I believe the issue is with the small circuit with the USB port. I bought my part from e-cell as well....
Thank you very much for your answers guys. Now I know that my problem is not unusual. however in my case the 2g signal receptiony is also to degradated. Please keep us posted when you get the spare parts from Hong Kong. If they work I will also order 1 myself.

OK, good news ... today I got my second part, and this one seems to work just fine! 3G and H+ are back! And of course it charges.
As I ordered 2 different parts at the same time from HongKong, I am not 100% sure which one I got, but I am quite confident it is the one from mingxing200808. The item I bought is sold out now, but he relisted it (at higher price: 6.90 USD vs 3.90 USD that I paid, still worth it though). Note that the picture posted is not the same as the part shipped (which was newer, at least in my case). Also note that you need to reuse the rubber cover of the microphone (e-cell included that rubber piece). There is also no adhesive on the mingxing part, but as far as I can see you don't need that either.
Good luck!

OK, good news ... today I got my second part, and this one seems to work just fine! 3G and H+ are back! And of course it charges.
As I ordered 2 different parts at the same time from HongKong, I am not 100% sure which one I got, but I am quite confident it is the one from mingxing200808. The item I bought is sold out now, but he relisted it (at higher price: 6.90 USD vs 3.90 USD that I paid, still worth it though). Note that the picture posted is not the same as the part shipped (which was newer, at least in my case). Also note that you need to reuse the rubber cover of the microphone (e-cell included that rubber piece).

Hi Guys, I have had this problem also after replacing the usb board, it has been a nightmare thinking that other parts may have been water damaged I replaced the loudspeaker and inner chassis which both have antenna components. After reading your post I ordered a used part from gaproducts on ebay at £3.85 and my phone is now perfect. By the way the defective one was from china via ebay and supposed to be genuine. Wish I had seen this post a month ago it would have saved me so much hassle, but hopefully will help others.
This is strange, i have the same problem after changing the Flex Cable + Charging port. I bought it from ebay (user name yake-gandi3388) so be careful. I requested a refund or replacement but not sure what the answer will be. The phone never connects now to HSDPA (H), it always stays on EDGE (E). On top of that the signal is somehow weaker than before, not significantly, but I can notice it
I thought that the Flex Cable+Charging Port are not linked to Antenna performance in any way Can someone more experienced explain a bit?
Also, anyone tested an aftermarket flex cable+charging port that is working ok, including the antenna performance and full 3G connection?
Thanks!!!
Ive followed about 10 threads about changing usb boards.About 1 person was happy,and the other 9 got other problems.
When they put their "faulty" one back in,the "new" problems vanished.
Most were replacing the board because of usb problem.
I thought they were buying faulty replacements.For all I know someone at Samsung could be "recycling" faulty parts..

I'm experiencing the exact same problems!! What's weird is that with other carriers (that work in different frequencies) my phone works just fine... I'll try buying another flex cable and will tell you the results.

Strange... I will try to check with other providers as well. On my side, I have re-contacted the Ebay member and he offered me an additional Flex Cable with no extra charge. Nice commercial initiative, however I am afraid that the next one will have the same issues Will keep you updated once it arrives.
Got this as well. I changed my USB board after it developed charging problems. The first one gave me a flashing battery icon & one of the screw holes didn't line up also. The next one fitted fine but I'm sure my signal is weaker. Compared to my friends S1 on the same network. He gets a stronger signal than me, stood in the same place. Replaced my loud speaker/antenna as I've also replaced the back chassis and think prising the speaker out might of damaged it. Think I'll try another USB board to see if it improves :S the 2nd board had the same Rev. number on it but looked slightly different to the original. (Sadly dont have the original to put back in to test)

I am signed up for a solution to this problem.
I had charging issues with the old port and replaced the board. The new board only allowed for an intermittent 1 signal bar. I put the original faulty board back in and had full signal immediately.
I ordered a second board and have the same issue. No/1 signal bar. Cannot make calls, it tells me "mobile network not available." I can connect to wi-fi with no issues though.
Unless a fix is found I am considering taking one of the new boards and my old board into a service shop and having the usb ports swapped.

I received a 3rd charging port board today, this one works some, but not as good as original. I'll post the number's printed on the board with there results in the phone.
Original Board: GT-i9100 REV2.2
R.B83 35
Original board worked great until it started having issues with charging/high voltage.
Replacement Board 1: GT-i9100 REV2.3
R.C42 10
This board would charge the phone and connect it to the computer, but would not connect to a network and would give no signal or a temporary 1 bar signal.
Replacement Board 2: R.B54
GT-i9100 REV2.2
This board would charge the phone and connect it to the computer, but would not connect to a network and would give no signal or a temporary 1 bar signal.
Replacement Board 3: GT-i9100 REV2.2
R.B83 36
This board both charges and connects the phone to the computer and it allows for a network signal. The network signal is not quite as good as my stock, but I think it will do.
I do not know what the board numbers mean, but I would guess the REV2.3 is an updated version of the REV 2.2. I think the compatability issue may come in the R._ numbers as Replacement Board 3 is the only one that works and is the closest R._ match. Maybe someone with far more expertise can shed some light on it, but this is my experience.

viva! the party from Hong Kong worked for me. For everyone which needs this part search for
the vendor on google. I am using my phone for the 2100Mhz 3 g band.

Good.
So whats the vendors name....or is it classified.

I changed my usb port as well due to not charging/over voltage, ordered it from hongkong via ebay.
Been using the new one for over 6 months now and i would be lying if i said i had any 3G problems. And someone already asked this in this thread but no one has answered it. How are usb charging port and 3G signal linked??

The USB board has the contacts to connect to the antenna in the back of the chassis. So replacing it with a sub standard part is affecting signals

Please let us know the vendor name on Ebay. As mentioned in my previous post, the vendor (user name yake-gandi3388) agreed to change my replacement with no extra charges. I installed the new piece...the signal is a bit better than previous one...but still lower than the original.
Can anyone advise a vendor that sells replacement part Flex Cable with a strong signal?

I an sorry for for the delay. I live in Germany and I use O2 ( umts frequency in the 2100 Mhz band) . I ordered the part from Hong Kong which Geronymous cited, didn't want to make specific advertising. The user is mingxing200808.
Regarding the question why does this affect the antenna, it is because antennas need to have a certain capacitive load in order to be adjusted and to transmit in a certain frequency range. If the antenna is not adjusted the signal will be reflected back . This capacitance is defined by the geometry of the antenna and might be changed/adjusted by elements connected to the end of the antenna. So the flex part acts as an adjusted capacity load for the antenna.
This is a very rough description, but I hopeit helps.

Finally got my 3rd USB board and my signal has improved a lot! Hurrah! Got from tjuk1980 on eBay. This board is a darker blue, looks a lot better than my second board which was a lighter greener colour, the logo and writing didn't seem as clear as it does on the new one. Getting 3 of 4 bars on H+ at home where as before it would stay on G and if it did pick up 3G/H by chance it wouldn't show any bars.

Edit: picture of the dodgy board - this gave me crap service so avoid that one!
