Lost SD and USB support

Hello,
I have tried attempted to root and flash a new ROM on my phone and now I seem to have lost SD and USB support. it does not recognize any of the SD cards i put it (doesn't realize theres an SD card inside) and does not recognize any USB plugged in.
I have HBOOT .80 and i THINK i got the root correct (lotsa problems along the way so i'm not sure), but i was able to flash a ROM (NexTSENSE) so i think it worked. now, i saw a thread about fixing USB support but that required SD support. and reading that made me feel like i was royally screwed. in any case, any suggestions? I think USB support is still kinda there since I can get it to recognize it in the boot menu. but when i try to do it in recovery and use the flash rom .bat, it says device not found.
it would seem that the main concern right now is that i can't get it to see my SD cards. any of them, even after reformats and whatnot.
i can't connect to HTC Sync or anything of the of the sort. usually when i charge the phone, you get the charging notification but i don't even get that now. sounds like a driver problem but i can't see what is wrong. my computer doesn't even recognize the phone as a device every now and then
Hope i provided sufficient information. New to android scene so don't be too hard on me please =O but yea, any suggestions are welcome. thanks in advance
edit: usb support... ever so slightly back. aka, it charges now. probably was drivers on my lappy getting funny after moving between bootloader and recovery and all that fun stuff

You have the usb brick issue. Check out the thread on that. Also once you are up and running again, root using unrevoked or the fake flash method. All information is available in the dev forum.

ok, i've done some reading and this is what i've found so far. my phone is stuck in USB debug hence no USB support and somewhere along the way, SD support was disabled. from what i see, the fix is to
first:
reload the step1 of root to get back to 1.15 and basic root access.
second:
from there, i can re-enable SD support using the command:
fastboot oem enableqxdm 0
third:
apply USB-Brick fix found in post 1 of thread
and then i should be able to reload ROMs as usual. is this correct?
and where exactly do i put in the command to re-enable SD support? this is what has be confused right now. along with the commands for the USB fix
i am using the tinycore method so i just have the step1.sh. and then in the same console, can i enter that command? should i do it after a reboot? or load back into bootloader to do it. (bootloader or fastloader)

OOOOK. sorry about the continuous posts. putting new info up so it isn't exactly a bump right?
in any case, i used the androidSDK tools and ran the fastboot from there and i think i re-enabled my SD correctly. i was then able to run the USB-brick fix found on modaco forums. all done and done. nowww, since i just went through half the root process (step1.sh with tinycore), do i need to finish it? or since i had already rooted before, is it all done now?

I'm not 100% sure about that as I haven't had to fix the usb brick for ages now!
Download and install titanium backup from the market. If it works fine, then you are rooted. If not, root woth unrEVOked or fakeflash.
All the older root methods that require usb during the root process leave you open to the usb brick again.

Hi fatpandas..
Is your phone ok now? Actually my phone also have a problem like yours last week..until now,i can't fix it..if now your phone ok,can u share with me..thnks in advance..

@csyrix
sorry to hear about your situation. after just being there, i can tell how horrible it is. good news is, if you really have the same problem, then it is definitely fixable.
now, i don't know what method you used to flash yours the first time but from what i've seen, they're mostly the same. what you wanna do first is do that step1 thing where you have a temporary ROM installed. (1.15?) same process as usual.
then you'll need to run 'fastboot oem enableqxdm 0' with phone plugged in while in FASTBOOT (back button + power button thing)
in case you don't know where to put that in, you wanna run that in your command prompt (computer) while operating in the tools folder of the android SDK. (thank god for my limited computer knowledge cuz all the instructions i found just say, "run this command" and like hell if most know how/where)
in any case, the end result will be you having completed step1 and having re-enabled SD support. then turn off phone.
then get the fix from this thread
move that to your SD card (micro SD adapter) and turn back on your phone into bootloader. go to the recovery menu and hold volume up + power to bring up menu and hit the apply: update.zip.
then all should be well. i then moved on to step2 to make sure i had rooted properly. may not be necessary but i remember reading that rooting a rooted device isn't a problem so i just felt the need to do it to be safe.
that should be it. the link provided actually has all the instructions anyways (i hope mine are a bit more clear), but if not, that link should be able to fill in the holes. g'luck sir

Any way to update FW without SD card or computer?

On Thursday the 29th my phone decided to take a dump on itself. Since then it has not been able to:
-Read any micro SD cards
-Connecting to computer doesn't fully allow USB connections, it detects something plugged in, but nothing else. No ADB, no RUU update, no Sync, etc.
-Cannot charge unless off
All of the above happened while trying to get onto the leaked Froyo. I cleared the cache and wiped the data then this happened.
I already ordered a replacement from Sprint (which I have yet to hear about), but I think I can fix this one by updating the OS.
Problem is that it downgraded me to a version earlier than the one that was on the phone when I first got it. Being on this version is causing a problem by not allowing HTC Update to even see any updates.
So basically I need to update without the use of USB or SD card.
Any help?

Thanks for the quick response.
That seems like it will be of a lot of help, but unfortunately adb cannot detect the phone.
EDIT:
It's also mildly amusing the way anytime someone also had this problem in that thread (the < waiting for device > in adb due to it not detecting the phone) people would just ignore it and continue on.

I have noticed that the computer can somewhat recognize the phone if it is in HBOOT USB mode. It is enough for the fastboot command to go through but return with a failed.

does adb work while it is in hboot? if so you should be able to push a pc36img.zip to it and fix it that way.

No, it only is able to recognize some things while in HBOOT. Example would be PDANet, which I used to be able to read the phone in the first place on Windows 7 x64, can see that the phone is connected. Adb still reads no devices though.

I'm pretty sure this happened when trying to wipe the phone to do a clean install. My assumption is that it wiped a file that was otherwise necessary to keep the SD card reader and USB port operational.
Is there any way that I can execute the "fastboot oem enableqxdm 0" somewhere on the phone without using adb?

Did another reset on it. Battery was low and turned the phone off without my knowledge. I turned it on to check if I had any messages or whatnot and got a message saying that the battery is low and that the current being given from the USB is not strong enough to charge it and to switch the cable.
What in the software would cause the current to be low?

[Q] HTC Desire HD Charging with USB but no USB Connection

As my topic says, when plugging in the USB to the computer the phone starts charging, but no USB connection to the actual computer. I tried with debugging on and off, tried with several ROMs but nothing changes it.
I tried to connect another phone thorugh the cable and that works fine so i know its not the cable thats the problem.
The version im running now:
Baseband version: 12.54.60.25P_26.09.04.11_M2
Kernel Version:2.6.32.39-cyanogenmod-g99f1050
Mod Version: CyanogenMod-7.0.3.DesireHD
Anyone got any idea and wanna help me?

goto setting>Connect to PC> and make sure "Ask Me" is ticked.
Im guessing that it doesnt ask you what you want to do and the phone by default charges i.e "Charge Only"

Do you not even get the icons in the notification bar?
If you're using Windows, have you got the drivers installed (sorry, I don't use windoze so I am unsure if you need them for this but seems to be a common issue)?

Well i have tried both doing "adb shell" with debugging on and then it says "Device not found", and tried to mount is as an USB disk to the computer and nothing happens.

I get the USB icon in the notification bar, but thats all. Yes, i have tried both with windows drivers and without (Cause it wanna install the drivers when they arent there), but nothing happens either way.
I even tried the phone to another computer and its the same there.. no reaction, so i think it´s something in the phone or kernel?

You could try reflashing the ROM without a full wipe (wipe Cache though). I doubt it's an inherent bug with ROM / Kernel otherwise there would be a flood of similar posts (checked nightlies as well).

I have already tried that with 3 different roms and its the same with all 3 roms

So that rules out problems with ROM or Kernel.
Next, need to rule out PC. Have you got another PC or laptop you can try?
Have you tried different USB ports (if using front ones, use back or any others that are on a different MB header).
Forgot to ask, when you say you tried mounting as USB Disk, do you mean you do get the option if you press the Charge Only icon in the notification bar of the phone?
And also, to rule out the SD card, do you have a card reader you can try it with?

Yes.. thats how i tried to mount it as an usb disk... i have tried mounting it in Clockwork Recovery Mod aswell... nothing there either :/

Not looking good!!
Last hope then is that it's a problem with the sdcard itself. Do you have a card reader on any of your pc's / laptop you can try?

Nope, no card reader. But i can send stuff to the phones sd card through wifi using myphoneexplorer
How can i install stock rom and kernel through clockwork? Or any way without having usb connection?

Unless the ROM you want is listed in ROM Manager and the Kernel in Kernel Manager (neither of which are fantastically up to date) then you will need to either find another way to get them on your SDCard or visit the the XDA site in a browser or XDA App, find the files you want and download them directly to your phone via the ether. You should then move them to the root of the sdcard and use Terminal Emulator to check the MD5SUM of the file before flashing.

well.. getting the files to the sd card is no big problem using myphoneexplorer over the wifi at home. but where can i find the stock rom with any mods that i can put on the sd and flash with clockwork mod?

Which stock ROM are you looking for? If it's the stock HTC OTA Gingerbread one them here - http://www.iloveabath.co.uk/index.php?dir=RUUs/
(Thanks go to @andyharney for that).
You mention stock with mods? Could you expand on that one and I'll get yo a link to the most appropriate ROM that suits?
Off topic: MyPhoneExplorer is great. Been using it since my early Sony Ericsson days - the original phone it was designed for, I believe.

Thanks alot mate!!
Only problem is that its and exe and i guess i have to use the usb to install those? :S
I meant Stock without mods ofcourse
I will check into that and install stock... i´ll update this thread with what i´ll try and how it works...

There's a PD98IMG version of an UNROOTED (you will lose root again) the Gingerbread ROM, give me a few minutes and I'll see if I can find it.
[EDIT] Sorry, a PD98IMG will allow you to copy to sdcard root, reboot into Bootloader and it will flash automatically.
[EDIT 2] - http://forum.xda-developers.com/showpost.php?p=13329691&postcount=96
They're Megaupload links though but you should be able to access them in browser. Take first link, rename it to PD98IMG.zip
Small Print: You do this at your own risk.

Thanks again.. will read up and see if i´ll do it

Hey guys
My first post
So i'm having the same problem. tried everything.
Any possible rom and nothing helps.
even the PD98IMG didn't help...
gave it back to the store, lets see what they have to say about it.
gotta wait a week or two

How?
I need a cable connection for that

Hard Bricked LG E980 USB device not recognised

My LG E980 is bricked. I can access download mode and that is it! I am unable to boot into recovery,
and the hard reset screen simply sits there forever. My computer only recognizes my device as an "unknown usb device."
I'm unsure what can be done about this, but I feel like this is better than the infamous QHSUB icon displayed when the device cannot be recovered.
Does anyone have a remedy for this problem?? I have GOT to fix this phone and can't afford to Jtag the device, but I'm losing hope that this is possible, PLEASE help. :crying:

Have you installed the LG drivers for your pc and tried the unbrick method?

Yeah dude there's an unbrick method. If this doesn't work just sell the phone on Ebay. http://forum.xda-developers.com/showthread.php?t=2302660

There is never a time when this device cant be recovered. even the qhusb is a fairly simple fix. ill go ahead and make a sdcard boot image tonight. do you have a 32gb sdcard? (or larger) and an sdcard reader, if you have those two things i can make an unbrick.img that you flash toi the sdcard and put in the non-booting phone and it will get you to download mode/recovery mode. ill have to check out what partitions are where as i dont wish to include my efs along with it all .

Happened to me.
1. With the phone on download mode and plugged in the computer; uninstall the unknown device on your computer using device manager. The computer should try to get the drivers for your phone.
2. If it doesn't. Repeat step one and install the drivers first.
That worked for me hopefully I'll work for you.

I do have a 16gb sd card, but I can pick up at 32 gb sd at my local best buy. I have an Asus laptop running windows 8 and it has an SD card reader. I am a little confused (semi-noob) as to how this will work because my phone will boot up, and the led changes colors on the home button for about 4 seconds and then the light stops flashing. The phone is stuck on the LG boot screen, and there is no way out of it but to pull the battery or to reset with power button. Of course no recovery as previously mentioned. I really just want to get back to stock, but I can't manage to get both the windows 8 computers I've tried to detect the phone in download mode. Ever since I switched to the Candykat rom 4.4 the computer wasn't able to recognize the phone, even when the phone was fully functional inside the rom.
I have tried it on my dads windows 7 laptop as well with no dice. Instaled LG drivers, uninstalled LG Drivers, uninstalled device from the Device Manager. I've done everything I could think of. I previously was in a Philz touch recovery, but every rom I tried to flash wouldn't work. I tried to flash another recovery from inside it and then the device bricked like it is now. What a head ache. If you think this method would work, I am more than willing to try it, just unfamiliar with what I need to do on my end.

Okay

I will give your method a shot, but I have done this a lot already. The only thing I can think of is I usually unplug the phone from the computer right after deleting the drivers and uninstalling in device manager. Maybe I should just leave the phone plugged in and see if the computer automatically downloads the drivers, but I don't think it will because I've tried to update the drivers before. It gives me an error code "10" and says the device has malfunction or stopped working This phone has been undetectable via USB since flashing the candykat 4.4 rom. Every computer I've tried (3) and every USB cable (3 again) has displayed it as an "unknown device"

I dont know lg's download mode, kdz, tot etc all that well. im more of a samsung guy. however qualcomm since the s4 chipset has allowed for sdcards that are properly formatted to boot the os instead of the internal emmc. here is a decent guide, just need to make teh image for this device. this will let your device boot no matter how bad it gets you are welcome to try with 16gb, the rule of thumb i know of is as big as teh emmc is use that same size or larger sdcard, however some people have had sucess withs maller, just not many that i know of. http://forum.xda-developers.com/showthread.php?t=2439367
however afaik the only way to reflash teh bootloader partitions is via kdz/download mode so perhaps the sdcard will let you get into that mode and then you can flash, so long as you keep your sdcard like that it will boot fully, but in order ot get your sdcard back you need to repair teh files on your phone .

Wow, that sounds awesome. I followed most of that. I access download mode on the device by pressing vol up and down simultaneously and plugging in the usb cable. I am more willing to try this, and if it works I will pay you from my paypal. I guess all I need now are those files to run to the sd card. I read the tutorial you posted for the samsung and downloaded the windows disk manager. I am eager to try this method, though it is admittedly very new to me.. If you can post those files, I will follow the instructions you give and pay you a little bit of money for your help!
I am a broke college student so it won't be much, but I really appreciate your response and information on this method with the qualcomm s4.

Here is the unbrick image. follow the guide for your platform (gunna guess windows) and write this to your sdcard after backing it up. from there you need to restore your partitions by flashing them .

Okay so I bought the 32 gb sd card. Just wrote the .img file you sent me to the sd card.
I powered on the phone and nothing happened, I got the same LG screen where the led flashes and then stops.
I followed that guide, but am I supposed to go to download mode instead of just powering on the device?
I got a little confused by the samsung jargon lol. I just want to know after I've written the unbrick.zip to the sd card
how do I get my phone to recognize the card is there? And once I am able to do that how do I "restore my partitions by flashing them?"
I do have the factory firmware set to flash through lg flashtool, but the phone can't be detected of course due to the usb issue.
Just want to say thanks for walking me through it this far, I feel like I'm close hopefully but unsure what to do next.

you wrote the image to the sdcard? i wonder if its because you still have the low level bootloaders that it may not be booting from the sdcard, normally this is done to fix qhusb errored devices. as for restoring the partitions all you would need to do is one its booted up push the unbrick image to the phone and use rooted adb shell to write it back onto your phone.

Possible hope??

I meant I used the windows tool to write the debrick.img to the sd card. But no dice, the device isn't recognised.
However! I installed a driver clean up tool and now if I plug in the device it is recognized as Android Original ADB Interface.
The LG Flashtools even says the port is ready! But I get the error code "10" "device cannot start, A request for the USB device descriptor failed."
So now I am stuck on that instead lol. This just sucks.

that sucks about the sdcard, it must be because you arent "truly" bricked. sorry i thought it would help ya :/.

What is the driver repair tool you used? I know this thread is old but I'm having the same problem. I was trying to root my E980 and now my computer wont recognize my device. The phone works perfect, its just when I plug it in to the computer it isnt recognized. How can I fix this?

+1
Just wondering if anyone's come across a solution to this besides a sledge hammer... been having the same "Code 10: Device failed to start" when in Download Mode, though Windows finds a driver fine when the phone is stuck on the LG screen... doesn't help much, though, 'cause it won't receive adb commands. I manually installed the LG USB Composite Device driver, which added a modem and a COM port, both of which Windows recognized to be active, but the LG FlashTool USB Viewer showed no open pipes. I'm a relative noob, so please feel free to point out the obvious, like an alternative to adb that the phone can always receive or a way to brick it the rest of the way so the MicroSD trick will work.

I came across this problem like the OP and just wanna let everyone know that you have to use computer with USB 2.0 port then the driver issue would be fixed.

[Q] Wiped everything with TWRP 2.8.4.0, now softbricked?

So just as the title says, but here's a little back story (might help).
I'm trying to help out a friend with his Bell Mobility i747M. He wanted to try out Lollipop, so I looked into it and said I could do it. Last I even touched his phone was quite a while ago when he wanted me to flash CM11, back when KK was still pretty new. So it's been over a year. I flashed CWM back then, got the ROM installed, and everything has been good ever since. Fast forward to now, and he wants to try Lollipop. I figured the first thing I should do is update the bootloader/radio, which went perfectly fine (after some researching, I chose 4.3/MK5 for his i747M). I tested them by booting back to the ROM and checking About Phone - everything was good. So I booted back to the old version of CWM, and thought it would be a good idea to get a more modern recovery. CWM or TWRP didn't matter, just as long as it was more up to date (I thought it might help with Lollipop compatibility). So I decided on TWRP, and I got the latest version (2.8.4.0 as of now) and flashed it. Successfully flashed, then rebooted recovery. TWRP is there and working. Great. Next step... I had the Lollipop ROM and Gapps already downloaded and ready to go, so in TWRP, I proceeded to wipe everything (system, data, cache, internal sd).
Uh oh... Half way through wiping, the phone reboots itself! Now there's no ROM, so naturally it has nothing to boot to. Try going back to TWRP, and I see the splash screen again. OK, false alarm... Well, not really... Because now it just reboots itself after the splash screen, every time. Can't get into TWRP no matter what! I can access download mode, but Odin doesn't recognize the phone. Yes, I have the drivers. In fact, the device isn't detected by Windows at all.
So here we are. Download mode boots, but Odin doesn't work because there's no communication through USB at all. There's no ROM on the phone because it was wiped. And TWRP won't boot beyond the splash screen.... Now what?? I tried the 80MB MK5 debricking .img on a 64GB microSD. It does nothing - besides, USB isn't reading anyway, so it's not like I can proceed with Odin.
I'm at a stalemate here... Any suggestions?
My friend's gonna kill me if I killed his phone I'm pretty experienced with several devices, but not much with Samsung. I've never seen anything like this happen before...

When connecting to the computer, have you tried different USB 2.0 ports and USB cables? Have you tried different computers? Different operating systems?
Is the phone recognized using adb or fastboot commands?

Yeah, I figured that would be the case. Just about done downloading Ubuntu which I'll boot from USB. I'll post back with results once that's ready. I should have it booted within 10 minutes. Once I get there and verify the phone connects, what would be my next step? Should I try flashing stock 4.3 first?

I would confirm the bootloader that is on the phone before flashing anything from sammobile.com.
You may be able to use fastboot commands to get the information by typing fastboot getvar all.

OK, in Linux now. ADB/fastboot won't connect. Tried different USB ports and cables, ones that I know work. No luck...
The only thing I can boot to in the phone is Download mode, so that's where I'm trying from.
For the record, ADB picks up my Nexus 5, so I know it's all set up right.
I'm gonna retry the debrick img, using dd to write it this time.

No luck. wrote to the SD successfully, and it just boots to download mode. Nothing else.
ADB and fastboot still do nothing

Maybe the phone's USB port is flaky?
Have you tried Kies to see if it recognizes the phone?

I don't have Kies, but I'm doubting that would work anyway. There's absolutely no communication between the computer and phone. Nothing happens when I plug it in. No sound, no indication anything was even plugged in. Running lsusb in a terminal doesn't show the phone either.
Edit: Downloading Heimdall (Linux-compatible Odin)...

Okay, forget kies. Sounds like a USB port issue. Does the phone start charging when connected to a power source?

Plugging into the wall makes the phone vibrate every couple of seconds, but nothing shows up on screen, and there's no indicator light.
The vibrations lead me to believe it's detecting something, but no indicator light worries me (unless that's just because there's no kernel)
The red light does come on if I plug it in without the battery.
Heimdall fails to detect the device as well (no surprise there)

If the phone was bricked, it would usually be recognized as a some sort of device under Windows' device manager which leads me to conclude that it is a USB port issue.

I agree that it is weird, because it's not coming up as a device at all, in either Windows or Linux, yet it does receive power.

I'm guessing here but it appears to me that the only left to try is a debrick image. Is it possible the battery is drained and needs to be charged?

The debrick image is what I've been trying. It's on a 64GB microSD. And I made a new one from Linux a few minutes ago (booted back to Windows now).
The battery was about 80% before all this started, and the phone powers on without being plugged in, so I doubt it's the battery.

Maybe you need a different SD card? Based on posts I have seen, it seems that certain brand/size combinations work while others don't.

I only have one card over 16gb...
Either way, I still have the USB problem. I'll need USB to flash with Odin. The debrick card only seems useful when Download mode isn't working, but that part works fine on the phone, even without the debrick card. My problem is with recovery. If I could run that from the SD, I think I would be fine - just flash a ROM. But I'm not finding anything for that (not surprised).
I thought it could potentially be a corrupt driver, so I tried using USBDeview to uninstall all disconnected devices. I tested it with a portable hard drive, which indeed had to reinstall after. So the program works as intended. However, the phone still isn't detected when I plug it in. No sound, no notification saying it's installing or install failed - absolutely nothing. Power goes to the phone through USB, with multiple cables and USB ports. Just no data connection.
I'm starting to think there's just nothing I can do...

The phone may need a USB port replacement. I know of no way to push recovery to the phone from as SD card without USB capabilities.

Yeah, that's what I'm thinking. Found this, and it's cheap enough... But that shipping!

You'd be better off getting it from China with free shipping. The problem is the amount of time required to get the part.
Maybe contact a cell repair shop to see how much it would cost to have them replace it. Soldering is not my strongest skill

Yeah, doesn't look easy. I already tore down to here, and visibily, it looks OK. I'm not so sure about soldering either :silly:
I appreciate your assistance.
