[Q] Fastboot OEM unlock without USB cable?

I had a problem with my Nexus One's usb port, the pins got bent, and so I sent it into HTC for repair. Well they told me it would cost $250, and that it wouldn't be covered because they suspected user damage. (I never dropped it, my cables just stopped working and I noticed the pins were bent, so I don't think it's anything I did wrong).
Anyways, so I decided not to repair the phone, and I would just hook up a wireless charging system from the Palm Pre and transfer all my data using wifi.
Well, when I got my phone back, HTC was nice enough to relock the bootloader for me, so now I can't install cyanogen, and I can't unlock the bootloader because I can't get a USB cable to work.
Is there anyway to unlock the bootloader without a USB cable? Any help would be appreciated.

I would try adb wireless (on the market) or SSH into the phone
Edit: which, these only make sense (and I doubt either work) if you still have root, which is probably not the case

Yea you can connect ADB over WiFi - but you need the cable (or root privelges) to switch to wifi mode. You can try of them one-click root apps, then get the adb wifi widget.

I ended up getting a USB cable to work if I held it at the right angle, so I got the fastboot unlock, couldn't send a recovery firmware, but I was able to use ADB to send the files over and do a manual root, and then put a recovery on the phone. So I have resolved my problem. Next time I would be sure to not do any updates if they ship the phone with 2.2 on it.

I believe that they use a standard microUSB receptacle, which can be removed and a new one can be soldered, for a fraction of the repair price. Moreover, with tiny screwdrivers you might be able to actually correct the misaligned connector pieces.

Problem is that the leads that actually make the contact have probably popped off of the ceramic part that they are normally glued to.
This will make it very hard to actually use the cable without bending the contact leads backwards into the case.
That happened to me once with an older phone.

Phew, My Shift is Back to Life: Thank God !

After frying my Shift motherboard sometimes last year I had given up any hope of ever getting it to work again. ( http://forum.xda-developers.com/showthread.php?t=701950 ). I tried HTC support to have the motherboard repaired or even to be supplied with a new motherboard without any success. Tried any relevant outlet I could think of that could source a motherboard but still nothing came of it.
I tried searching for anyone selling a Shift at the cheap but the few ebay listings I came across showed that the device cost is still very high. I started a link here hoping somebody with a dead Shift could sell it to me for spares but nothing came of it. To make matters worse the thread was moved to Xda Marketplace and it was lost and burried in the market. ( http://forum.xda-developers.com/showthread.php?t=937322&highlight=shift+motherboard )
But as fate would have it the other day I searched the Marketplace and came across a guy who was selling 2 dead Shifts and high capacity Shift accesories and spares including 2 Gb Ram stick, SSD and higher capacity batteries. But I was a bit late to the party! The sale had been on for almost 2 months and most of the valuable items had already been sold. But I was still in luck as the dead Shifts were still available. I bought one of them as the other was a complete shell even though the motherboards had problem as the power switches had detached and gotten lost for the both of them.
Fortunately an electrical engineer friend of mine was able to remove the power switch from my dead Shift and solder it to the purchased motherboard. It was a delicate procedure but I can confirm that all went well and my Shift is now back to life. Infact even with the replacement motherboard my Shift booted with all the data and settings exactly the way it was before roasting the motherboard.
Just thought of sharing my experience with fellow proud Shift owners here.
I would also wish to thank the seller (TopRowGuy) for a very swift and smooth transaction. Thumbs up buddy. ( http://forum.xda-developers.com/showthread.php?t=961663&highlight=shift+clio )

Hi Ed, congratulations for resurrecting your Shift and thank you for posting here the info.
While having the spare Shift and old motherboard at the hand, would you please be so kind to have a look at the circuitry of the socket for external headphones&microphone. My interest is related to the non-working condition of the Shift phone on external headphones&microphone with the custom ROMs.
Therefore could you please check if the socket is simply switching mechanically between internal speakers and external headphones, respectively internal microphone and external microphone (just like in any other audio-tape device) or other circuitry is also involved invalidating the phone function when external devices connected. What else gets disconnected when plugging-in that is influencing the phone? Can the microphone switch be overridden to use only the internal one permanently and let only the headphones be switched?
I'm pretty sure that there are many members here interested in your answers to the above questions. So thank you for contributing to this community!

Thank you Axel.
Ok I will check the switching mechanism for the mic+headphones for the Shift and report back. If relevant I will also take close-up photos with both the the jack plugged in and plugged out. Since I have the extra motherboards boards (both winmo and Vista) I will try severall things. But if i am not wrong the headphone jack is actually attached to the windows mobile motherboard and not the windows vista motherboard....
I will do the necessary and report back. Of course I am also very much interested in finding a solution for the century old problem of non-working external mic phone side..... I will also snoop around the Memory Card Reader and see what gives ......

Thanks Ed!
My idea is that we all might get lucky if the phone would work on external headphones (i.e. have some privacy), but with the internal microphone (you have to speak-up loud anyway).
I expect that, just like in any classical audio set, the switching circuitry on the audio out side gets the signal out of an audio stereo IC, which is led further to the ext phones socket and involves nothing more than the connection wires, socket, loudspeakers and earphones. If so, that means that we are OK on the earphones side. Of course this is an assumption and means that there are no active speakers or anything of the kind linking the audio outputy to any input of the mciroprocessor.
I also looked at 4 contacts 3.15mm coax plug of the HTC earphones and microphone and the contacts for the limitation comes from the microphone circuitry, this can be arranged by disconnecting the internal microphone from the ext socket and leaving it connected all the time.
My guess is that the internal microphone is hardwired directly to the socket and is not going trough the motherboard PCB (printed circuit board), in which case can be desoldered from the socket and resoldered to the audio in signal path (also coming from the socket). With this mod inserting the plug will have no influence any more on the microphone path.
In reality things can be more complicated since the same ext socket is serving both WinMob side and Vista side. I wonder if there is a single audio out IC or just the two processors deliver in paralel to the same load (speakers).
Looking forward to your findings.

Axel,
I had a long and hard look at the mic and audio jack/port and I am afraid there is nothing much to gain from a physical examinations of those items. To start with the audio port is covered with a black plastic on the outside so you cant really see what is going on inside when you insert the jack.
The audio port is connected to the phone mobo and not the Vista mobo. The phone motherboard is not spoilt and hence I would not want to strip things from it as it can come in handy at a future date. The internal mic is also attached to the phone motherboard through a printed cable. Problem is without first booting the Vista Bios the phone side does also not boot. I am trying to see if there is a way I might get the phone side to boot. If I can succeed that way I would then disconnect the mic from the phone motherboard and see whether the wired mic can become active as you have suggested.
But all this I am only doing with the dead Shift because of course I cant touch the recently resurrected Shift. I wonder if there is absolutely any way of being able to boot the winmo side without first pressing the power button (attached to Vista mobo) which is missing from the motherboard that I am playing with??? If that was to be possible I could try various things with the mobile powered on and probably even be able to use the mobile side ad forget about Vista on the cannibalized Shift?
Here are some photos of the audio jack port and the mic connection area. Sorry the images are not great as i took them at night and in low light environment.... These are self-explanatory but the long and short of it as per your inquiry is that it is possible to disconnect the internal mic from the motherboard. As to how the wired mic would behave when the internal mic is disconnected is subject to real tests with a working Shift. As to whether you can solder these around I will leave that to those of us who are more technically oriented.......

Hi Ed
I'd read your post. Also, I have som problem about my Shift
the conditions are:
1. it can not be turn on even vista or snapvue
2. When I switch on the power button, only the green light was on at the bottom of LCD screen.
3. I can hear the fan turn on but nothing happened
4. When I use the charger, the battery can be charged and finished it.
Do you think that the mother board have something wrong?
The HTC care center want me to change the board but it cost a lots.

Vincent

If the green light is turning on I think yours is a software problem. What about the mobile side? Does it come on when you press the button for switching between the Snapvue and Vista? Try that with the green light on and then we can try troubleshooting from there.....
In the meantime try press FN+F10 immediately the green light comes on and see what happens.....

Hi Ed, thank you very much for your endeavour. Of course I didn't expect to work in this experiment with the ressurected Shift, but only with the spare one.
What kind of a switch is the power switch, is it a single section switch or with multiple sections, is it a bistable or a tip-switch. I expect that it is a single section tip switch which is connecting 2 contacts on the pcb only for a short while while you press on it. If this is correct you may connect the 2 contacts with a jumper-wire just to start-up the Shift. It is true that the Vista part will start first, but I don't see a big draw back in that.

Thanks again for the pictures, maybe some other time you'll have the opportunity to come up with more clear ones.
To get some privacy while using the phone my intention was to switch only the speakers on the headphones, but still using the internal microphone of the Shift. That would require some small modifications to the jack-port.
I didn't get it exactly how many motherboards are there inside the Shift? Are there in 3 pcs, i.e. Vista mb, Winmo mb and phone mb, is that right?

Hi Axel,
The Shift has 2 motherboards - Mobile and Windows Vista. But both are connected where the 2 boards get into contact with each other through connectors on each side. There are no cables/wires involved but just direct connectors between the 2 motherboards where they come into contact with each other.
Apparently most of the connections take place inside the printed circuit boards so you cant tell which connection goes where. But of interest is that both the mic and the audio jack are all connected to the phone motherboard yet they dont work in the mobile side. So either these have been physically disconnected within the circuit board or it could be a software issue. Remember how we could not use GPS or phone functions until the great rom breakthrough by the likes of Thaihugo and Cmonex....? I still believe that the issue of wired mic not being active is a software issue.
But the SD Card is a different story as this is attached to the Vista motherboard. It is very likely that there is no physical connection between the Sd card and the mobile motherboard. Well I might be entirely wrong here as come to think of it there is a solution about accessing SD card from the windows side but Vista has to be on...... Will look for that thread and read some more and see how the connection is established.
By the way I did home-made switch for the dead shift's motherboard. The Shift was able to power up and boot but it appears that the Lcd cable is dead (or perhaps the lcd screen itself is dead but most likely the problem is with the cable). I was able to connect the Shift to the Tv through a Vga cable. But I could not do much with it as the Vista software appears to be corrupt. Further the HDD connection cable too is not in very good shape. I hope to get the Hdd cable to be able to do more tests on this Shift using the Tv as the external monitor.
This other Shift will be the official guinea pig and I am willing to make various tests with it as soon as I get a working Hdd cable and re-install windows. However there is a big limitation to this too because apparently the windows mobile side does not show in the external monitor. In other words even if you switch to the mobile side using the Shift button the external screen does not change and is only active for Vista......
But I can tell the snapvue side is active as I was able to call the sim card number inside the Shift I was using for tests.... My intention is simply to use this Shift with my Tv for internet connection and as a basic pc in the living room. I confirmed that the internet connection to the Vista side is active even without having any access to the windows mobile screen. I made these tests with the Hdd cable from my good Shift for a few minutes and thus did not make extensive tests.
So guys I will get back to you with more tests once I get a working Hdd cable which I may have to import from China (parts4repair.com). I might then end up with 1 Shift and half a Shift......

After playing with my other Shift as described above I believe your problem is not the motherboard since the power light is coming on and the fan is coming on when you power your device. So chances are that your Lcd screen is not getting any signal from your Shift. Yours could be a simple problem with a disconnected Lcd flex cable or problems with the lcd screen or damaged lcd flex cable. Easiest test for you is to get Vga cable and test your Shift using an external computer monitor or tv that supports Vga in cable..... Hope this helps.

Thanks PlayStation, great post, thank you for your endeavour!!! Looking forward for further details.

[Q] How to determin whethet its HARDWARE or FIRMWARE fault ???

Hi.
Yesterday my phone stopped recognising the earphones/speakers when plugged in ?! It doesn't show the "headphones" icon any more, and even on full volume I can here sound/music only on the left speaker/earphone very silently. I've tried 2 different headphones, 2 different speakers as well ... ale same results.
Is there a way how to determine whether it's firmware/software issue or hardware ???
Thank you in advance.
P.S. : what I did prior to noticing this problem - we have a new sound system in our school that has two places for connection. We were using one of them, but couldn't use the another one, because of lacking cable. Once the cable arrived and we connected the cable to the system - I've tried whether it's working with my phone. It played the sound only in the way, that I've described. So we have tried it with an Iphone (the same results) and later PC, which played the sound correctly. I'm still waiting for response from the Iphone owner, whether he has the same problem - but could the cable/system caused the fault ??? Do you think, that my phone would get damaged by "some current" ???

From what you say, it seems to be an hardware problem. To test this, you can perform a factory reset and if the problem persists it's definitively an hardware problem.

one possibility is you got dust/lint in the earphone socket. the cover broke off on my defy, and i occasionally have to pull some lint out using a toothpick

I've checked that as well, but couldn't see anything there. Well never mind now...I've sold the Defy and bought a new one. Such a great phone deserves that everything is running as it should
Thank you for your help.

Samsung Focus USB connectivity issues

Hello everyone!
After finally getting an external battery charger, I've been able to use my Samsung Focus again.
I'm still, however, having USB connectivity issues.
Here's what I've tried.
-Reinstalling Zune
-Using other USB ports on my laptop.
-Using another computer
-Reinstalling the Samsung USB Driver
-Using a few different microUSB cables, including one from another Samsung phone
-Cleaning the microUSB port.
-installing WMDC
EDIT: -I've also made sure my phone's in Zune Sync USB Mode in the Diagnosis app.
When I connect the device, it says "Unrecognized USB Device Detected", I've tried replacing the drivers with the Zune driver, which works half the time, but it still has a yellow caution icon next to it. Saying things like "the device cannot start", "a request for the USB device descriptor failed.", and "device enumeration failed".
So now it's down to it being the software on the phone or the phone microUSB port.
I'd love to hard reset and see if it's the software, but if it's the port and I've reset, then I'm screwed.
I've searched numerous forums, including this one, and still haven't seen any working solutions.
EDIT: Also, I've noticed in the Battery Status app... it'll say "charging" for a few seconds and then go to "discharging".
Some specs:
Phone:
-Samsung Focus SGH-i917R
-Rev 1.3 on AT&T
-Windows Phone 7.10.8107.79
-DFT Freedom ROM [I guess it was a Rogers version]
Laptop PC:
-Dell XPS17 L702X
-Windows 8 Release Preview 6.2.8400
-Intel Core i7 2720QM @ 2.20GHz
-NVIDIA GeForce GT555M (3GB) @ 1080p120
-16GB DDR3 Dual Channel Memory
If anyone can help, it'd be huge!
And if there's anything I've neglected to mention, please let me know and I'll edit the post.
Thank you so much!

So I ended up doing a hard reset, and much to my dismay, it's still spitting out USB Device Not Recognized. It reset to the DFT Freedom (Chinese New Year) ROM I have on there, which I didn't quite expect... I'm wondering if that's the problem or not. When I get closer to my upgrade next month (Lumia 920, here I come) I'll likely get ballsy-er, and might even dismantle the phone and see if there's anything physically amiss with the port.
Still, any suggestions, feel free.

Have the same issue. Did same as you searching internet for any hints.
Have had this issue for 6months now, just been living with it and syncing files to skydrive and Gmail with WiFi.
I even took phone apart down to the circuit board level to see if anything noticeable or maybe connector or any components with broken solder. Hit it with some heat from SMT soldering iron to get a bit of reflow in that area, didn't make a difference. Ohmed it out as far as I could go thinking data lines were shorted or something...no luck.
I'm leaning toward this being a USB receiver chip level issue inside the Samsung Focus. Was hoping it would be something simple. Who knows, maybe that ROHS solder wiskering issue is haunting me somewhere in that phone.
FYI this issue came up around same time I had the repeated chiming issue. The one that only goes away when you do plug in the USB connector with charger or PC. Luckily haven't experienced that issue in 5 or so months. But did have it dissappear for a month then reappear again back then, so anything goes.
Note about 2 months ago I plugged phone into computer and it tried to sync up, zune popped up. I got excited, but after remove and plug in again, have not seen been able to get it back since.

I too am having the same problem.
First of all, be warned - if you decide to pull apart your Samsung focus, it's easy to do, but I found that the SMT port for the antenna is VERY fragile.
Steps to open it after turning it off:
1) open back plate.
2) pop out battery, sim, and expansion memory
3) take out the 7 screws.
4) with a flat blade (whether that be a screwdriver, flat tweezers, or even a guitar pick), insert it in the gap between the chrome and the FRONT of the phone, then gently twist to pop the "back" off.
5) You will now need to separate the volume buttons from the side of the phone (the plastic comes out easy enough).
This is a sticker back, and getting it off is hard and can tear easy.Take your time.
From there, there are several flat PCB sections that have multipin connectors hidden under them. They need to be pried off - they do not require a lot of force.
Now the big reason not to do this:
The f$#%ing antenna connector. It will pop off, but the connections to the mainboard are VERY fragile. I'd suggest pushing against it and use tweezers to rotate and lift the connector.
All that said, I've been looking for a cause for the problems you've been having - there is one other symptom you haven't mentioned, and this has been a problem for a lot of focus owners - the constant dinging. You may not be getting it (if you're phone is on vibrate, then it's no surprise), but every time the device "sees" the usb connection to charge, it Dings (at least, for me).
Yeah. I *want* to either fix it, or drop it in the toilet.
My phone is off any warranty already, and Samsung refuses to help. I'm not buying any more Samsung products ... and before this, I was humming and hawing between the Nokia 920 and the ATIV S (for the screen size).

[Q] Need to fix usb connection, no adb/fastboot. Alternate motherboard points?

Well the microusb on my N7 has been half broken for almost a year now (worked only the first month before it was dropped with a cable in). Its always been able to charge and it must be a hardware issue, my other N7 connects fine to the same computer port and cable. I've also tried many other cables and computer.
Now normally this isn't a huge deal as I just transfer things I need over samba but I now have a new situation.
An OTA bootlooped it, its with stock recovery, factory reset still results in a bootloop, I can get to the bootloader fine but since my data connection never works fastboot is a no go, replacement microusb modules are $60+
I replaced the screen last month myself so my warranty is gone.
I'd like to make a temporary connection to the motherboard just to fastboot a factory image and twrp. There seem to be a few data points that could work, this thread shows one beside the battery connector http://rootzwiki.com There is also the one on the microusb module itself above the actual plug but that whole module could be messed up so I'd rather try another.
I'm not great with soldering and there is no way I could solder either of those spots on my own. Are there any other spots that would be easier? Would only the data +/- points be needed to the cable? Or is the 5v and ground needed to?
Thanks!!

If I'm not mistaken if you buy a n7 official dock. It connects via the 4 round brass dots on the bottom of your n7 I forget what the proper term is lol. Anyways its the same as USB as far as I know. Or find the pinout of them and make something.

Looked into it, its charge only, no data. Thanks though
