Lately my lumia 525 has been bricked..And my pc cannot fild it when i am connecting through usb.. What should I do?
mattschwantes said:
Sometimes it is just a dead battery. Verify in Device Manager that absolutely nothing appears/disappears when you connect/disconnect the cable to the device. Sometimes it appears in ports, sometimes HID or Keyboards.
If nothing at all appears, and your battery is good, then your only hope is R3209 trick. That should only be done by someone who is comfortable working with the circuit board.

What is R3209 trick? Can you explain me?

Are you talking about connecting usb by soldering some weirs inside the logic board?
mattschwantes said:
The process is described here: https://forum.xda-developers.com/wi...indows-phone-internals-unlock-t3257483/page79
There is no soldering involved but do be careful. I already killed one device doing it this way, but I have also saved several this way.

Okay but can you tell me a fresh location of GND in the logic board?

And which side of the register i should connect with gnd?
mattschwantes said:
as i said, short the resistor. after that, it doesn't matter which side you connect to GND.

Thanks a lot mate, I'll give it a try tomorrow ??
mattschwantes said:
Good luck. Just be careful prying the cover up above the resistor. those surface-mount components are very small and some are quite close to the edge of the cover. no need to fully remove the cover, you can just pry up the side/corner you need to access.

sorry for my late reply... phone had connected successfully. and did everything he told. i did all things successfully, still it doesn't boot up.
mattschwantes said:
That would not make it boot. It would allow the phone to be detectable by Windows device manager and allow you to restore the bootloader using Wpinternals.

yeah, but it didn't work for me. i pushed the bootloader. but still it is dead not finding by usb unless i connect the resistor with GND

This guide is for the situation where your phone is not booting and the three-button combo for getting into download mode is not working for some reason, and you have tried all the other solutions in the FAQ. It won't help you if you can already get into download mode but something else is going wrong with the flashing process, for example you can't get Odin to communicate with the phone.
If the phone's bootloader is still intact, that is you see at least the white Galaxy S/Samsung/AT&T logo or the "PC ! Phone" logo on the screen, you should be able to force it into download mode by connecting a homemade jig that simulates the Samsung "Anyway" field test jig. You can buy these jigs online, or make them using a micro USB plug and a resistor.
If your phone screen is always black, that is it does not display the white Galaxy S/Samsung/AT&T logo when you switch it on, then sorry, this jig will not help you.
If this helps you recover your bricked phone, please donate to the CyanogenMod developers: go to this thread and click the link under "SUPPORT US". Thanks.
If you don't want to buy a pre-made jig, you can build one yourself from a few parts. You will need:
1. a micro USB plug that you can solder onto. If you are not confident with soldering or you just want a tidy solution, buy this micro USB breakout board from Sparkfun.
Otherwise, get a cheap micro USB cable and cut the sleeving off the plug with a sharp knife. You cannot just wire onto the cable because this jig uses a normally-unused pin (pin 4) of the micro USB plug which will not be connected to the cable.
2. a 301k resistor. You can buy one from Digikey, or make one up by joining several resistors together in series, for example 3x100k and 1x1k. The resistor value does need to be fairly accurate (I would guess within 1% of 301k) to trigger download mode. 300K seems to work for everyone so far.
Procedure:
1. Solder the resistor across pins 4 and 5 of the micro USB plug. Do not do this with the plug plugged in to the phone as the heat could damage the phone's USB socket. The pins are shown in this diagram ("Micro-B"). On the Sparkfun micro USB breakout board they are labelled "ID" (pin 4) and "GND" (pin 5). When the plug is plugged in to the phone they will be the pins closest to the headphone socket.
2. Make sure the phone is fully switched off by pulling the battery, waiting 5 minutes, then replacing the battery. Do not switch the phone on.
3. Connect the rigged USB plug to the phone. Try not to touch the pins on the back of the plug or the resistor(s) as you are plugging it in, as your skin resistance could affect the resistor value seen by the phone. You do not need to press the power button. After a few seconds the phone should go into download mode.
4. Disconnect the rigged USB plug and connect a regular USB cable from your PC to the phone, then you should be able to flash using Odin.
For more information on how this works see this thread and this thread.
I knew you guys would figure it out - well done. I will build one before I attempt rooting and flashing

Well we only have one confirmation so far. If it does work for you please let us know what state your phone was in prior to using it as I'm interested to see what problems it can repair.

I would try but my phone is with samsung and I'm not all too handy with a soldering iron =)
Hi, anyone have pictures of the cable with the resistor soldered? I am just unsure where to solder it, is it on the micro usb cable side or the standard usb (on which end of the cable?) and which part of the cable do you need to cut open? (i heard there is a pin/wire that usually isn't used?)
Also, if i decided to go with the breakout board, i would only have to get the board+301k resistor plugged in the 4 and 5 pin and plug it in the galaxy and would boot in download mode?
Thank you very much!
Thank You!

Only the micro USB plug has 5 pins (regular USB plug has 4) so it has to be the micro USB plug. You have to cut the sleeving (insulation) right off the plug. You can disconnect the cable from the plug or leave it attached, but don't plug the other end (the regular USB end) into anything.

Were you able to flash it after it went into download mode? Did you try pulling the battery for a while?
Thanks for your reply. I got it working by your suggestion. Seen many others saying leave the battery out for a while and also seen peeps saying do the 3buttonbootwhile inserting the battery.
As my home made jig was soldered with the pins out of the plug I wiggled it/them about in the socket to ensure a connection was made, then I inserted the battery.
Panic over. Flashed JP1 with 512. not been on for long so cant confirm all is working but looks promising.
I am putting this gadget in a !!!!!!S.A.F.E!!!!!! place.
Also will be available for borrowing in the S/SE UK if anyone is interested.
Im gonna leave playing firmware for while as my heart cant take much more at the mo
Many thanks to OP and others for various tips.
The short answer is yes

Thanks everyone who helped solve this problem. I have a i9000 and flashed it with the captivate rom. I could not charge the phone so I tried to reflash with original software, I used the 803 pit file. It stopped and i waited for about 10 minutes and disconnected the phone and I got the screen of death.
I did this last week and was going to take it to Samsung after the Froyo upgrade came live and I was going to say that it happened when I tried to upgrade.
Guess what I made this USB factory jig and I was so happy that it went into download mode. This made me so happy many thanks and i will wait until the official upgrade comes.
I used a old nokia USB connector stripped the plastic off and bought a 300k resistor from Jaycar for 45 cents and this must be the best 45 cents I have ever spent.

I have a Samsung Vibrant T959 TMobile US with 2.1-update1, Baseband T959UVJI6.
The battery is fully charged, it registers in the phone as fully charged 100%, but when I hit the power button I get a progess wheel that gets stuck, then the phone just turns off. It never gets passed that wheel, it only displays for a second then dies.
However, when I plug in the USB and hit the power button, it comes right up like it should. Then I can unplug the usb and use the phone just fine. Its almost as if I need to jump-start the phone with a power source.
I have reset the phone, even re-flashed the stock firmware using Odin. Same results. I have even swapped batteries with a buddy just to see if that was the case, but I still got the same results.
Any advice or suggestions is GREATLY appreciated. Thanks Very Much In Advance!
Anybody? Any ideas?
Well, that is new to me...
I'll preface with, I have no clue how/why that is happening. But, this is what I would do:
1 - If really opposed to rooting, I'd call T-Mo / Samsung and get a replacement.
2 - If I liked my phone and wanted to make it better, I'd root it and flash a custom ROM. It likely would take care of the issue, as it clearly is not a hardware thing (well, I say clearly).
Worst case with #2, ODIN back to stock and then do option 1.
possible solution
also it says "USB connected" even when cable is unplugged? I had similar problem.. I tried everything, flashing, changing batteries.. none of that was useful. Then I find some post on some forum that says it might be corrosion, so i scratched my USB with thin wire and everything worked fine, but also scratching USB I was doing one more thing. In my opinion, I think that it's not corrosion. I think that USB is slightly bent (middle part of it), try to bent it in other direction, possible that it's too close to edge. That solved my problem. Tell me if this helpful for you, sorry about my english

i think i can get what you are saying, cleaning the usb port on the phone right??
BUT how does this affect turning the phone on?? if usb port is rusty, it will only affect charging, not turning the power on?
I experienced this identical issue last fall -- the USB would always say it was connected, wouldn't startup unless connected to actual USB, but otherwise worked fine.
Take your phone apart and look at the solder joints on your microUSB port... mine all had cracks in them or had broken free. I re-flowed the solder while holding the port down and it resolved my issues. (put on some flux, and run a hot soldering iron across the joints, clean up... it's not very difficult. just be sure you don't short out any of the pins.) I also added additional solder to the four points that just hold the mircoUSB to the circuit board. It's been rock solid since

See if there is a TV or electronic repair place still in business in your area. Or post an ad on CL asking someone with knowledge and skill to do it. Be careful they aren't an idiot just wanting 20 bucks and happen to own a soldering iron.

I would go through these guys they are top notch helped me when i soft bricked my wife's phone. He even convinced me that i could fix it myself when i was ready to send it to them for a jtag.
They can replace the usb plug if thats the issue.

I would test to see if my battery is bad first before i went about resoldering, it could easily be a bad battery.

No my stock battery is charging and i did buy a separate battery. same issue.
So I go to plug in a flash drive and just noticed that one of the USB pins has been bent.
Does anyone have any experience with straightening out the pin or replacing the entire USB port.
I tried Warranty and they said they dont cover this.

Try fixing it with a "straight pin", a pair of 2x glasses helps. If you smashed it back, you are just going to have to play with it.

Two days ago my battery was extremely drained, i followed a video tutorial on YouTube to fix it by removing the battery and put it back, but after doing this my wifi became so bad! for example, if there's 10 networks nearby i only could see 4 of them with its half strength.

I don't think so. Looks like hardware problem i guess. Compare with another phone on same location, check signal quality.
Perhaps when you removed the wires, you damaged the connector on the wire itself or the mother board.
Hopefully its the wire which would be a quick, easy and inexpensive fix.
To reach the battery you have to undo the rear plastic housing, unscrew the MB cover, unclip a few connectors remove the power/volume ribbon assembly and disconnect the antenna wires.
It may be worth taking the entire phone down to the MB and redoing the process one more time.
Take your time and make sure everything is connected one last time before you power the phone back up again.
There's a good chance something could have been overlooked.
20 minutes of your time could save you some heartache and pain

You "popped" it open? It looks like you didn't remove the three screws before you did the popping. It must have taken a tremendous amount of force to break the plastic of the three screw channels. Either that, or you are incredibly strong.

There is no hole and there is no button installed on this device. Even if a reset switch were installed, it wouldn't work because no reset switch is defined in the environment. Without that definition, it could never ever work.

You picked a very difficult device. It would help if you were good with boards.
Ideally, it is easiest to work on this device with the uart connection installed. And there is a lot more work beyond that, including very tedious work shorting the board. Read the other thread here for more information.
