[LG Optimus 3D] felipeamh:
hello. Long ago I visit this page, for reasons to upgrade my cell phone or other matters ...... in this last time I gave a lot of work p920H LG Optimus 3d. In this forum were throwing ROM's based on each update that came out, but in many cases CHILE or other countries, the connection was lost forever data (3G). For this reason I saw the need to know more, and found the solution by joining various data, especially to extract a file. KDZ, then use Smart Update, and this is where I could finally use the "baseband" (. Fls) and the rom (. bin) 3D Optimus had to fix. I used the tool b2cmarwin, something, to install the version in force. KDZ 20A and 21A then, I used the. Fls with 20A version. Bin 21A version. Stressed if I had a lot of patience, because to do each update had to do the configuration of the cell (first use), make ROOT, install ROM manager, flash recovery (had to do it from rom manager, flash from the PC and it did not work) .... etc.

Well, I hope I can explain better after sleep (xd), with links and an image, and also ask if they can edit the 3 ROM are updated on the development forum for the 21A version, because that still does not change much and I can combine them with the baseband 20A, which is what keeps the 3G connection.

Greetings and thank you very much to all the people who make it possible to customize our equipment n_n!

Hi all, I have a HTC HD2 leo T8585 with Windows Mobile 6.5 Professional, I noticed that with any browser you can access chat facebook, and the only program with which you can access it Fim Mosko mobi v2.21 . Once installed and configured by entering your login data, opens a window that says <Please confirm FIM from the desktop and subsequently signing again> <Connection Failed>.

Since this is the only program where you can view the facebook chat you can give me some advice?

Thank you in advance

greetings

and you aren't asking this in the F.IM thread because....?

its telling you to login to facebook through your usual desktop, and you will be presented with a box assking you to confirm fim as a trusted application. (Probably)
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] Tunafishing:
the problem lies in the recognition by facebook.

Facebook recognizes only windows mobile apps, but not Fim recognizes Mosko.

Until a few weeks back everything worked fine .. I do not understand
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] samsamuel:
oh well in that case perhaps its an app that facebook have dropped support for? perhaps they've had a disagreement?

Is it possible to replace the regular nook contacts app with the stock Gingerbread one?
[Barnes & Noble Nook Tablet] old_fart:
i have not done this for the 'contacts app' but i have done it for similar items. the titanium backup app will let you 'freeze' and then also 'remove' just about anything. freezing is better and safer ( and can be un-done ). . be VERY careful and read up on it
[Barnes & Noble Nook Tablet] titanshadow:
Tried that, but contacts.apk still won't show up on my launcher even after reboot.
[Barnes & Noble Nook Tablet] old_fart:
ug, well that infers that it is inter-related with another piece of the gaaps...

wish there was a 'dependency' tree to those pieces...
[Barnes & Noble Nook Tablet] lavero.burgos:
No you can't but is safe to remove stock nook contacts app. When you install gmail and create an account it should give you the option to sync contacts.

You can also use any other contacts manager app from google play

Guys, do you know if it's possible to install an internal microsd holder connecting it to the usbpin of 30pin connector?
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] hoss_n2:
No ;) , the chasis is so slim to carry an internal 3rd party micro sd reader , but you can buy external usb hub with sevral ports and use card readers , or buy the official micro sd card reader from samsung
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] zooster:
But it's still possible to use the internal connector and slot, ready for the microsd holder.

This is the holder:

And below is the mainboard of the tab
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] RavenY2K3:
Where is that from, where can you get it etc... I'd pop my tab open if I knew I could do that to it.

Search on ebay: p7500 memory holder

The only problem is the missing connector on the mobo. It's the same as the one of jack3,5 and similar.

You have to find that micro connector and then airsolder it on the mobo, hoping that is not missing also some resistor around.
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] RavenY2K3:
Ahh, looked at the image again, I thought it was a zif socket, so on second thoughts, soldering components to my tabs mobo is beyond my capability. Shame really, I would probably pay to have it done if there were a place capable of doing it for me.
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] jacampb2:
Thank you for the awesome nudge in this direction! I am going to take a stab at this and I will report back.

I bought one of the SD holders on ebay, took my tab apart to verify the original idea-- while the card reader will fit in the place circled in the photo above, I don't think that it is going to be ab absolutely perfect fit. Again, I will report on what it takes.

As to the 10 pin connector, I believe that I have found the correct parts. I ordered some a few days ago, and they should be here by the 24th. I will know for sure then, and share the part number if I got it correct. If anyone else wants to hunt for them though, they are known as board to board connectors, as well as mezzanine connectors by some manufacturers.

Although they are SMD, they should be just barely large enough to solder with a real iron, a hot air rework station would be awesome, but I have been doing SMD work/rework with a normal iron for years. It takes lots of magnification, a steady hand, and tweezers, but ultimately it can be done.

The only big question I have, is where did these SD readers come from originally-- it say's p7500 on the silk screen on the reader, but as far as I can tell neither the 7500 or 7510 ever came with external SD... hopefully it will be plug and play, but I am going to refrain from hacking my tab's back up until I verify it does work.

Thanks again for the idea!

Later,

Jason

Good luck with that, I'll look forward to hearing how you get on.
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] zooster:
You're welcome mate, please post the link where you have found the 10pin connector and let me know if my find was workable.

Cheers
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] jacampb2:
zooster, I will happily post the part number once I verify it is the correct one. I don't want to put it out there, have it be wrong, and then have people upset with me. I also ordered both the "male" and "female" halves, mostly because the connector is kind of a "hermaphrodite", I suspect the half we need is the male half, but the manufacturer drawings are the same for both plug and receptacle (go figure, stock drawings...), so I ordered both. The part I am hoping is correct is from Molex, and part of their "slimstack" series. That and measurements will get you to where I am at ATM, or PM me and I will let you know number, or just wait for Tuesday and I will let you know.

There are literally dozens if not hundreds of similar style connectors out there, so this is kind of a best guess right now. It does seem like this style is somewhat standardized anymore, so hopefully there are a lot of manufacturers simply making the same things. Seeing as Molex is one of the worlds largest supplier of interconnects, it is a pretty good starting point.

So far I am out about $20, and I have poured more money down the drain after other projects that didn't pan out, so bare with me and I'll let you know what happens.

Later,

Jason
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] johho:
Very very interesting and I'm looking forward to hear about you're results.

Small question the pictures above show.the 3g model, right? I think I can figure out the Sim slot left from the possible sd reader slot.

I have the wifi one, how the hw mod will work there too.
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] jacampb2:
I don't know about the pics, those are zoosters. The picture of the back side of the tab though is named p7500-- so maybe. All I can say, is that I took mine (GT-P7510) apart again a few days ago, and it looks virtually identical to the pic. I didn't hold the tab next to the monitor and compare-- but it looks like it has the same amount of room along the top as the one in the picture.

The reason I said that it didn't look like it was going to be 100% drop in, is that the card reader does not sit flat in the area marked. In fact, there is a small foam pad with a silver jacket right below that spot, the card reader was on top of that. I removed it, and it still did not lie quite flat. Definitely not like any of the other assorted little components in there that are not retained by any kind of screws or adhesive, just a form fitting cavity. My instinct is that there is going to be a bit involved in getting the card reader to stay in place. The other challenge was that it appeared it might sit to far inside the case to be able to easily insert and remove cards. You are of course limited to the layout of the parts that are there, so there is not a lot of room to come up with a better mounting scenario. So, first and foremost we need to see if even when populated, if the reader works. If it does, then I will move on to trying to figure out mounting solutions.

If it's not 3g, the sim holder, although correctly inserted, will be unuseful
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] drhunter:
I'm following this with interest too.

Is the SD card slot spring loaded? If it's going to sit too far inside pop some tape on the front and back of the sd card so that the two pieces stick together and give you a tab to pull on.

I do this to my camera memory cards so that I can keep track of different cards when I'm out shooting.
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] jacampb2:
Yes, the card slot is spring loaded-- at least the one that I got is. I like the tape idea though, if worse comes to worse, that might be a solution. Now I wish I had snapped some pictures when I test fit this the other day. I didn't think about it, was just excited to see if it was going to really be possible. The thing is, it looked to me that it might be more than just a little to low in the position it appears to go. I say "appears to go" based on the original picture, and the length of the flexible printed cable. There is a certain alignment/orientation that has to be with what there is to work with. I can't really explain it any better than that, but hopefully you guys understand.

It is certainly possible that it is just the looks that are deceiving, but like I mentioned earlier, I am going to verify working hardware before I deal with making it accessible and stably mounted.

I sure might be dense, but where is the sim card slot in the original pictures? zooster, would you mind circling and uploading again? Or just a good description. I thought that it was supposed to be right next to the SD holder, but I must be missing it if that is the case.

I did find that these SD card holders were *only* in the pre-release/testing p7500's. I found a very few pictures of the units in tact online. It would be awesome if anyone with the development tab and the SD slot would shoot some internal pics for us!

Thanks,

Jason

NM on the sim card reader location. I just figured it out. Found a Utube video of a tech tearing down a p7500 because the owner stuffed an SD card in the sim card slot :eek:

Anyhow, I'm thinking the tab in the picture on the first page might be a p7510 as well. You can see that there is no flexible printed cable coming from under the metal cover that holds the sim reader in place. I also am quite sure that my tab had that cover as well. That cover might be the solution to mounting the SD card reader. Dollars to doughnuts they used something similar to that, if not the exact same as that one to hold the SD card reader in place.

I'm so excited I could squirt! I am really looking forward to UPS tomorrow or tuesday.

Later,

Jason
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] zooster:
Yes it is a 7510. As you figured out the sim card holder is located at the top left of the picture behind the metallic grid.

Pay attention in soldering without an air station solder, you could destroy pads and tracks.

I'd say that the holder with the cable fits 99% the slot, the pads for microzif connector are a the right distance, the only one remaining doubt is if you are able to solder it safely and correctly, and if it will just work. My concern is only about the possible lack of some resistor in the connection with the chipset.
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] streetrider nick:
I am going to be paying close attention to this thread, I am interested to see the results. I am interested in this even if the micro sd was not accessible from the outside of the device. I would just pop in a 32GB card and let it stay there.

Having 48GB of storage on my tab would be sweet, especially if a good working Ubuntu port becomes available!
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] jacampb2:
No joy guys, connectors were right, soldering was a *****, but went ok. Installed card and nothing, tablet doesn't seem to recognize it at all, so either disabled in the software, or it needs more than just the connector. In the pics you can see where they're is a large unpopulated area next to the sd card connector. i think we need a service manual, or someone top get values from one of those rare pre release tabs...

Sorry for the bad news, I'm going to bed, midnight shift tonight...
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] tghockey07:
Maybe someone needs to write the drivers for it. Are you sure it's getting power as well?
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] zooster:
Well, don't loose hope. Yes, there could be some resistor or some bridge to be shortened, but I think that the problem could lie somewhere else.

The tab has already a "sd", it's the internal one. Maybe it cannot see 2 sd at the same time. So we should swap from the internal one to the external or turn the internal sd into internal storage. Or maybe there is some flag in the software to enabled.

Maybe a porting of the firmware of the new tab, with sd slot, will help.

Btw did you check with a tester if the soldering has gone fine?

Could you please share the parts names?
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] nakedninja42:
Been watching this thread, great job getting the part installed! Does something in the kernel as well as the software need to be enabled to get it to work?
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] zooster:
Maybe just a mount point?
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] decatf:
No expert here but I don't think the sdcard would show up in /mnt unless it was pretty much plug and play.

What about looking for the any sign of the device showing up in the dmesg log or in /proc/kmsg ?
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] jacampb2:
I managed to research my own answers-- I can ADB into the tab and get the dmesg log next time I try to mount a card. As for the last_kmsg, it looks like the tab might write that one at each boot, so they data in there is not likely to mean anything as I pulled it hours after I put the card in. Keep the ideas coming, whatever info/logs I can pull when I get back to testing, I am game for.

Later,

Jason
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] zooster:
As I said it's also possible that the tab can mount only one sd card per time.

If we could have access at the tab 2, I think it could help, for software and hardware.

[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] zooster:
I think that there is already some version with sd slot. Here is a pic of that

If we could take a look at that mainboard maybe we could figure out if and what is missing to make that sd reader to work.

Anyway I noticed that the empty pads close to the microconnector of sd holder you soldered are very similar to the ones close to the microconnector of simholder.

If someone with a 3g P7500 with a stock simholder installed can take a pic of his mainboard, we can understand if on those pads close to sd holder should be soldered something like chips or capacitors or something.

If there is something close to simholder it has to be very similar to what is needed (if needed) close to the sd holder.

Ok guys, let's try to find a pic of the mainboard of a P7500. I'm quite confident there will be resistors and similar close to the microconnector of the simholder.

I've read the service manual of the P7500 and there are resistors pictured close to that connector.
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] tandfeen:
Well I do have the P7500 and want to help but I'm a little afraid of breaking my tab opening it. Is there a big risk of that?

[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] johho:
Small question, is the sim holder usb too? Maybee its possible to connect the sd reader to the sim reader port and see whats happening? It seems they have the same connectors?
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] zooster:
Maybe... Who has a P7500 and wants to help the project giving it a try...

The sd holder is quite cheap.

btw I do suspect that all those sd holders on sale on ebay are the ones built for early orders by samsung and after they changed plans about sd slot someone is trying to sell them to gain something from "unuseful" spare parts.

Who knows, maybe they can support us, they have all the interest ;)
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] zooster:
We could also take a look at the mobo of a P7100. Just to see if by any chance they left some connector with resistor unused but ready for the usage...
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] jacampb2:
Tim, that is exactly what I was talking about. The center pad is more than likely heat sink area like you say, but still no ideas on the package. I will try to spend a few minutes researching the package later tonight.

In other news, I did find a handful of pictures of the insides of the pre-release tab with SD card slot. You can find the article here: Clicky, I am not going to post copies of the pictures unless they give me permission. I emailed the site editor last night and asked if they had any higher resolution pictures they could provide, and if I could have permission to post their pictures here. I have yet to receive a reply, but you guys will be the first to know when I do. The area of interest in that particular tab is populated, but the pictures are poor enough quality that you can't really make much out except for being able to make a bit more educated guess as to which components are caps and which are resistors. Values are left to the imagination, and frankly, when you get bellow a 0805 package size for SMD resistors, sometimes you are left with components that are not labeled at all, so these pictures might be all the help we can get... Anyone have any of the fictional software from CSI that will sharpen those images into visibility :)

Ok guys my post here has nothing todo with the micro sd holder, although good luck with the work.

But since some of you opened their tabs and had a look at the mobo:

is there any chance of upgrading a wifi only model with a 3G module? Because i found a site with spare parts. Now i want to know if i can somehow solder it to the mainboard if there is space..?? or no chance?
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] jacampb2:
BeatB, you may have seen earlier in the thread that we mentioned that the 7510 has a similar unpopulated area on the board where the Sim reader is attached. At the very least you will be in a similar boat as to what we are looking into here, for certain the connector as it is not present, most likely the nearby circuit, and write possibly other component changes in other undetermined locations to support the cellular radio. Probably possible, but most likely cheaper to sell what you have and buy the tab you are after. I am a huge proponent of DIY, but I think in your scenario the risk far outweighs the benefits.

zooster, thank you for the new pm, the link worked. I have just had a few minutes while at work to glance at the service manual, however, i did see that in the section on level 2 repair, all the pictures show a Tab that while missing the sd card holder, still has all the component locations for it populated. The bad news is that none of the photos are high resolution. It does have me wondering though if the launch version 3g tabs were populated. If so, we need to get word out and to have people look, at best, this might be plug and play for them, at the least maybe they can help us on hardware and someone smart can look into software???

At any rate i have my fingers crossed. I'll share whatever else i stumble across as time permits.

If you notice those pics from fcc approval are related to a 3G 7500.

Hopefully Sammy didn't empty those pads suddenly before the marketing.

I'm quite confident that for the very first commercilized mobos of 7500 sammy did take out only the sd holder, leaving in place those SD pads populated, emptying them only in a second time.

So, I think there are good chances that an early manufactured mobo of a 7500 has got all those chips in place.

So, please: who has early got a GT-P7500 (3G) as soon as commercialized can please take an hi-res snapshot of the mobo?
