Memory and Sim Card undetected NEED HELP !!!

Hi I had 6 months ago a second hand HTC tytn 2, has been working very well till last week. I been watching the movie on my phone which was stored on memory card (4GB SanDisk Micro SDhc). Then I deciced to put some more tunes on my phone... so I went downstairs first to get drink after I pluged phone to PC and I found out that somehow my HTC can't detect the card... So after 2h of taking card out and in I decided to reset the phone to producent setings. However that didn't helped i tried to download some kinds of ''sdhc fix drivers'' but its also didnt work. Today I woke up in the morning and I recognised that on my phone that sim card is missing... but is in the phone so I tried to clean up the place where sim card is ... I took card out and in few time as well but still nothing .... I reseted device to originals setings again but its failed as well... I was operating WM 6 and today i changed to WM 6.1 and I upgraded the radio to new ones because I was thinking that it may be the case.
Any advice because im quite noob.
Thanks

there are a few threads about similar issues...you can search for these threads to learn more information about your issue.
i can guide you about the possible cause. if you notice, BOTH of the items that are failing (SIM and memory card) are located in the top half of your device...the half that carries the screen and slides over to uncover the bottom half that has the keyboard.
this leads to a design that involves mechanical moving parts...and so there are "ribbon cables" that connect the various parts in the top half (SIM cradle, memory card cradle, front buttons, screen, touch pad, ear piece, notification LEDs) to the motherboard in the bottom half.
...and mechanical and moving parts often cause wear and tear and, eventually, these delicate ribbon cables can come loose or even break. my bet is that the cables for the SIM cradle and memory card cradle have become faulty. try to see if your device has better luck in detecting the SIM and/or memory card with the keyboard slide out.
also remember to search for other threads about such similar issues.

I too have similar problem with my TyTN II. First it started with the SD card detection problem followed by intermittent SIM card detection and recently the failing of the touch screen. My unit is coming to 2 years this March. The hardware is still in a very good condition as it is always protected with the phone pouch supplied.
Can the "ribbon cables" be replaced? My HTC agent in Singapore quoted me S$700 to replaced the mother board. They are telling me indirectly to buy a new phone instead. Their advise is very sad.

You can buy a new main flex cable on ebay for about £25-£30 GBP, possibly cheaper, it's a full disassembly job to fit it, you will need to be confident in your ability to completely dismantle the device and put it back together again.

impossible task? save internal sd

Greetings. The other day I was at the beach and this wild wave appeared and got my phone wet. The phone turned itself off and I removed the batt. I re-inserted it not knowing the phone turnred itself on automatically and it turned on but i quickly took the batt off again. Thing is, it doesnt turn on anymore. So I was wondering if theres a way to remove the internal SD card from the motherboard and somehow addapt it to a new mother board. I know it might sound hard but I NEED to save the info on that phone. It's basically my computer and I'll do anything to save that info. Thanks!

Well if you have good soldering skills and know what to look for you could probably swap them out.

So, if it is possible to take the chip away from the board and solder it to another working one, which one would it be? My phone was giving signs that it might work but it doesn't respond anymore. Anybody heard about this procedure before?

[Q] HD7 Resetting problem

HI,
My HD7 keeps resetting itself at random times and its driving me insane. I have tried different apps to see if its that and no joy, new case to stop the chance of overheating its happened about 20 times in the last 4 months. My question is would replacing the motherboard help and if so where would I learn how to do this? I have changed the screen already so I would be willing to take it apart.
Thanks

It's absolutely a possibility that it could be due to a faulty hardware issue. The problem is that there are many reasons that can cause the device to randomly reboot.
Anything from -
Software - apps/XAP's, tweaks, registry changes, WiFi, OS version and radio version
Hardware - Faulty motherboard, SD card, worn parts and broken/damaged soldering joints.
Was the problem with the device rebooting present before or after you changed the screen? If the problem wasn't present until after you changed the screen then it's possible that there is a bad connection of some sort in the device.
Also what OS version is the device on and are you running a custom rom on it?
The actually disassembly shouldn't be much different from when you replaced the screen other than you have to separate the motherboard.
If you've exhausted all other possibilities and are pretty sure it's the motherboard and want to change it take a look a this thread and there is another external link in the thread too -

Here's a video that will give you an idea on the disassembly -

Ok thanks, so I had the phone from new, unlocked but using the 3 network. It started before I had even dropped the screen and put a custom rom in it, I was in a very hot country when it started so it might be slight heat damage. I have looked at the links and have now added them to my favourites. Although there is no direct link to a complete ribbon breakdown I am sure I can do it. Thank you for your help and once I have tried all aspects I will report back thanks.

Like me
I used the phone without the SIM card, no reboots or locks and reboots.
I'm using SIMs from a carriers using 850MHZ and 900MHZ all gave me reboots and locks, before the "solution" I used a 1900MHZ SIM with no problems (??? weird!!!)
Since the solution, I use my SIM without problem,
What I did:
1- Take the SD card and format it with sector check (long format) to see if there's a problem there, also give me manufacturer, capacity and class, if the card has it. Mine is a Sandisk 16GB Class 4
2- Raise a little the antenna connectors (2 copper fins near the sd card), BEWARE!!! they are FRAGILE!! if you break them (like me), you'll have to get some copper fins and use soldering iron (like me).
Believe me, I'm using my HD7 with no problem since then...
any question, here I am...

I have the sam reset problem but in one way. Yust if i use a Data connection to go on web. After random time, my HD7 start to restart itself. No warming or something else (mean overheat) of a phone.
What it could be? I am desperated
P.S. Problem starts when i am bricked my phone and went to "service" to do a JTAG flashing of it.
At first time after JTAG my phone warming up at a bottom of a phone (where an sd card settled and antena) ans start to reboot after Data connection enabled. After my complain to service they opened them again and told me there are all clean inside and after that my HD7 not wrming up but stil random reset after Data connection on web (HSPA+).
Any advice please or to throw my HD7 in garbage .
thx

[Q] SD Card issues with N1 after taking apart for screen clean

I've searched quite a bit and didn't find anyone with the same issue. I even told my mother she was lying to me about my being special (as recommended by the "NOOB video").
I took my N1 apart according to a very thorough youtube tutorial and cleaned the lcd and touchscreen because I had dust coming in around the corners. Before this, there were no problems running CM7.2 and my 16gb generic class 6 micro sdhc card worked with not a single issue. Afterward, as I marveled at my beautifully clean screen, I began to notice that the card would eventually stop working, not loading programs, wouldn't allow me to save anything to it, etc. I've tried a 8gb toshiba class 4 card and a generic 2gb class 2 card. The only one that seems to have any stability is the 2gb card, where I can install apps for the first few minutes of the card reading to it, and then it's done. I can't save maps to it or take pictures. Music wasn't accessible. I've reformatted in windows (fat32) and checked for errors with all the cards. No problems. The 16gb card eventually threw out corrupted card errors, which Windows could fix.
The 2gb card works thus: the apps I've managed to move there (by installing on the phone and then rebooting & moving to sd asap after the reboot) all work. Kindle works, my Bible, etc. etc. all the apps work. Maps can't access the maps I've downloaded, but otherwise loads just fine. I sometimes can take a picture or two, but usually the camera says I need to insert an sd card to use the camera (even though the 2gb card is inserted). 8gb and 16gb cards don't work (as described in the previous paragraph).
Not sure what the deal is. Could I have screwed up the sd/SIM ribbon cable when taking the phone apart? replacements are cheap (like $6.50 shipped on ebay), but have I destroyed more than that? Should I take care of the problem using software fixes instead? Thanks for your input.

Bump. I'd really like to get some input before deciding to gut it again
Thanks!

solved?
I believe I have it working, but want to let it run for longer to be sure (sometimes things stopped working after a few minutes, sometimes after a few hours). I took the phone apart and took off the copper foil that went around the SIM & SD card slots. It was mashed up a bit from earlier disassembly and my guess is that it was shorting out some contacts on the pcb beneath it.
So far I seem to be able to take pictures & video, utilize my cached maps, use programs, and play music as I had been able to before. This is all on the 2gb card, however. I'll work on switching over to the 16gb card soon to see whether the problem is gone forever.
Just a side question - will removing the copper-colored foil endanger my phone in any way? I'm guessing it was in place as some sort of shield, but I've seen quite a few disassembled phones on the interwebz without that foil in place. Any advice there?

ok so I repair phones for a living and to be honest, sometimes its just not feasible to put that copper foil back and I have really never noticed any negative effects from removing it. you should be good to go man.

Well, it seems to be solved! I've been using the 16gb card (it's actually a Strontium card, not a no-name) for a few days and have also discovered using an ext3 partition to make more space for apps. Running without a hitch!

Dead phone (salt water), how to save photos from internal memory?

So, title says it all - my phone died because of i was taking pics in sea, and it looks like it cant be fixed. Thats not a big problem, I already had it for 1.5yrs and was thing about buying a new one, however - I seriously wanna backup photos from internal memory. Is there any way how to do it? Has somebody some experiences? Or it's useless to try? Phone is completely dead, only thing which works is, when i connect charger, notification diode turns red. Otherway impossible to turn on, and in service they said it can't be fixed cos there is lot of salt inside.
I understand that, but at least data should be easily recovered - damn, internal memory, it's just some stupid SD card attached to motherboard, or am I wrong?

If you can't even enter fastboot mode then i think it's pratically impossible, sorry. Teoretically you could (and i can't stress this enough) solder your internal memory chip onto a new motherboard, but it is way too expensive and (more importantly) plain ridiculous just for some photos (and i wouldn't know if it actually works).
Next time enable cloud backup!
