USB brick and adb not working

I tried to flash CM7 RC2 onto my phone last night. I usually do this manually, but last night I did it through Rom Manager which I think was probably my first mistake.
Anyway, the package flashed fine but after a reboot my SIM and SD card were no longer recognised. So I went into recovery (Amonra) and wiped ready to flash the update manually only to find my SD card wasn't recognised: E:Can't mount /dev/block/mmcblk01p (No such file or directory). So, left with a phone with no ROM.
I can still get into recovery and bootloader but that's it. I've seen a few posts on here with regards to USB bricks, but my phone is no longer recognised by adb. However, I haven't accessed the phone via adb for some time now, so not sure of the reason I can't connect is my PC setup or the phone. I've got the HTC Bootloader device appearing when I plug it in via USB though.
Can anyone advise on anything I can do to sort this?
Thanks

Might be a driver issue when your in recovery. Re-install the drivers for the device using Device Manager and point windows to the driver directory within the SDK folder.

[Q] Cannot boot device/cannot boot into recovery/not recognized in Download Mode

I HOPE SOMEONE CAN HELP THIS POOR UNFORTUNATE SOUL....
My device is a Sprint Samsung Epic 4g.
I was running SleeperROM with a MTD partition map and had CWM v5.0.2.7
I downloaded TWRP 2.5 and then rebooted into CWM.
I flashed the TWRP and once it completed it said to reboot recovery. Within CWM menu I selected 'Reboot Recovery'. Nothing happened. So I proceeded to do a battery pull to manually boot into recovery.
>>When I attempt to boot into recovery, it just hangs at the SAMSUNGwwwdotsamsungdotcom screen. I tried the manual recovery boot by holding down:
a. Both volume buttons+camera+power (which always worked by releasing buttons after second SAMSUNG screen flashes)
b. Voume down+camera+power.
>>Device hangs at SAMSUNGwwwdotsamsungdotcom screen when I attempt booting device.
>>I am able to get device into Download Mode. But upon connecting to PC (Windows XP) , I get the USB Device Not Recognized flag.
Device Manager lists it as Unknown Device.
I have tried all USB ports. I installed a PCI USB 2.0 card as well. All USB ports give same result.
I have tried 2 of my USB cables, 2 of my roomate's USB cables, and 1 of my neighbor's USB cable.
I have installed and uninstalled then following several times:
Samsung_Mobile_Driver_V1.3.800_For_SPH-d700_Epic_4G
Samsung_USB_Driver_for_Mobile_Phones_v1.5.14.0
Samsung_Usb_Drivers_x32
I tried getting drivers via PDANet, MobileGo, and Samsung Kies.
Heimdall's Zadig option lists device as Unknown Device, thus not possible.
I'm into my 8th hour of frustration. Any help would be appreciated.

Err if I recall correctly, that version of CWM is BML only. If that's the case, then you are on BML and not MTD. You should manually uninstall all drivers off the machine. Reboot and run a registry cleaner, like CCleaner. Try to install the drivers again.
Hopefully you will be able to get that installed properly. If not, then use another computer. At least you aren't bricked, just caught in a hung boot.
So reflash that version of CWM, and from there you can flash whatever.

You can also try using heimdall in a virtualbox with linux to flash to stock if method above doesnt work.

[GUIDE] Troubleshoot MTP Driver Installation Failed

This is a comprehensive guide for troubleshooting the 'MTP Driver Installation Failed' problem on Windows 7
specifically for the GT-I9300, but also applies to other phones (except the part about Samsung and Kies).
This guide combines all the tips and tricks found around the web that have had results in resolving this issue.
If at any point you're fed up with the problem, keep in mind that there are free apps like USB Mass Storage Enabler
that enable UMS mode on your phone instead of MTP mode.
First of all try removing the battery for 3 minutes and restarting the phone and trying then (if you haven't already).
Ok lets start.
For troubleshooting purposes,
1. Remove your Sim and Memory Card.
2. Always use the USB ports at the BACK panel of the PC
rather than the front panel and the original USB cable provided by your manufacturer.
3. Download and install the latest version of Samsung Kies
and make sure to check the 'install USB driver' at the end.
Try the following to pinpoint the source of the issue:
1. Ensure that you have USB Debugging switched off. If it is on,
switch it off, reboot your phone and try to reconnect.
2. Try a different USB port at the back panel of your PC.
3. Try a different USB cable.
4. Uninstall Kies and USB Drivers. Open up USBDeview
(in the SGS Toolkit or from the web) and uninstall all drivers that say
'Samsung' or 'GT-I9300'.
Reboot and reinstall Kies and USB Drivers and try to reconnect.
You can find USB Deview here:
http://www.majorgeeks.com/files/details/usbdeview.html
Ok so none of this worked for you. Lets try finding the source of the problem i.e. either your phone or windows.
- Make a nandroid backup of your current apps/settings. Copy this backup,
megawipe and your Nandroid backup of your STOCK ROM to an external SD card.
Boot into recovery and flash megawipe. DO NOT reboot the phone. Restore the stock
ROM from your external SD Card. Do a data wipe/factory reset, wipe cache and wipe dalvik cache. Reboot and plug in the phone to see if it works.
Megawipe can be found here:
http://forum.xda-developers.com/showthread.php?t=1832326
If it works, then it's a problem with your ROM or its settings.
If it doesn't, it's most likely a Windows issue as we've excluded everything else that it could be.
Its my phone!
- Boot into CWM and flash megawipe. Flash your preferred ROM/gapps from scratch as per the developer's
instructions. DO NOT flash backups. As soon as you're past the welcome settings pages, connect the
USB cable and see if it works.
If it doesn't then your ROM has a problem with MTP mode and you need to contact your ROM developer about it.
If it does, then it's a problem with your settings. Use the stock nandroid from here on:
Its my settings!
1. Make sure that you have USB Debugging Disabled.
2. If you use apps like Gemini App Manager or System Tuner that disable apps on certain events,
make sure you didn't disable anything related to USB connectivity.
3. Try to restore system apps like media storage or anything else that might have been
necessary for your phone to work correctly.
3. Start from scratch. Install programs and settings one by one and figure out when
it no longer connects to your pc to find the culprit.
It's Windows!
1. Download and extract the latest MTP Driver from here:
http://drivers.softpedia.com/dyn-search.php?search_term=SAMSUNG+Mobile+MTP+Device+Driver&x=0&y=0
With your phone connected, go to Control Panel>Device Manager>Portable Devices
Double click the MTP Driver and go to the Driver tab. Click 'Update Driver'. Now click
'Browse my computer for driver software'>Let me pick from a list of device drivers on my computer>Have Disk
and browse to the folder you extracted the drivers to. Hit OK>Next.
See if it installs
2. Open Start>Run>Regedit and browse to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\
Browse to these two folders and delete the registry keys called 'UpperFilters' and 'LowerFilters':
{36FC9E60-C465-11CF-8056-444553540000}
{EEC5AD98-8080-425F-922A-DABF3DE3F69A}
Reboot your system and try to reconnect.
If the keys don't exist, create them and delete them:
-Right click>New>MultiStringValue>UpperFilters
-Double click the key and enter any random value
-Connect your phone now and let the install fail
-Disconnect the phone and delete the key you created
-Reconnect the phone
2. Uninstall Kies and drivers with USBDeview. Install the MTP Driver from here, reboot and try to reconnect:
http://www.microsoft.com/en-us/download/details.aspx?id=19153
3. Install the latest Windows Media Player from Microsoft. If you don't like it, you can always remove it when you're done. Reboot after install and connect your phone to see if it worked.
4. Try an OLDER version of the Samsung USB drivers from below. Uninstall all the current drivers with usbdeview and then install these. If you know of a date when your usb connected just fine, use a driver closer to that date:
http://drivers.softpedia.com/dyn-search.php?search_term=Samsung+USB+Driver+for+Mobile+Phones&x=0&y=0
5. MAKE SURE YOU HAVE NO VIRUSES OR TROJANS ON YOUR SYSTEM AS THIS CAN
COMPROMISE SECURITY!
Open Start>Run>cmd and type this into the command prompt:
net localgroup Administrators "local service" /add
Reboot, and reconnect your device and see if it works.
5. Do a clean install of windows, install the motherboard and video card drivers, then install Kies and USB Drivers. See if the phone connects.
If not, update using Windows update and try again. Don't install any other programs
until this step is complete.
Thats the end of the guide. If you've tried all of these steps and failed, then it's a good idea
to just give up and use one of the many alternatives.
Use UMS Enabler or simply connect your sd card to your pc directly rather than from the phone.
You can even do wireless transfers using ES-File Explorer or Samba filesharing.
Hope this helps!

None of those worked to me. i tried using drivecleanup, reinstalling wmp, installing kies, debug mode, removing upperfilters but everytime went back to the same error. What worked to me was:
- download file from that post http://forum.xda-developers.com/showpost.php?p=37042201&postcount=28;
- extract files from that package to some folder (;
- delete all wpdmtp* from \windows\system32;
- plug phone (it will give an error installing drivers);
- go to control panel -> system -> device manager;
- right click on mtp and poitn to the folder of extracted files;
after that, windows was able to install mtp properly.
Thanks to user Israelleite for the download.

[Q] Copy files from PC while in recovery mode?

Hey there,
I just wanted to update to another ROM and put the .zip file on my device and then rebooted to recovery and wiped my cache etc.
Somehow the .zip file is missing as well now though, I'm not sure why but it seems to have been deleted when I cleared the cache, etc.
Now I'm left without a .zip file to flash and a totally wiped system without a ROM :/
Is there a way to copy data from PC to the Nexus 7 device while in recovery mode? I tried connecting it via USB but it doesn't show up...
edit: Well after a lot of reading it looks like fastboot is the only option for me. Google USB drivers don't seem to be compatible with Windows 8.1 64bit and therefore I cant get my device to show up in "adb devices". Luckily "fastboot devices" works and I guess I'll just try flashing the stock recovery image now.

That's why I have bought an OTG cable (B letter inscribed on the cable, the others I've tried (4 models) without that B, didn't work with my flo, dunno why) and I have an USB strick to get files like zips from my PC. Or get a stick with both micro USB and USB connections.

Dead SM-605??

Hi All, sorry this is a fairly long post.
i recently "Upgraded" my SM-P605 to Android 9 and it has been working fine.
i have, however, been experiencing connectivity issue with file transfer via USB.
i have tried several cables (3 Genuine) including a brand new "Generic" cable and keep getting the "device descriptor request failed" error.
i have also tried multiple PC's, loaded all recommended Samsung drivers and finally relented and replaced the USB port in the tablet itself, which still did not fix the problem.
Convinced after all of this it must be software related, i then decided to re-install and earlier version of Android which i copied over to the Tablets internal memory.
i logged into TWRP and wiped the tablet ready to reinstall Android 7. and when i tried it says the zip file is corrupted.
i now have a tablet that wont load the zip file i have, wont read from an SD card in the tablet or OTG (via TWRP) and is unable to connect to a PC via a usb cable..
if anyone could offer any suggestions i would be extremely grateful as i dont want to "Dump" this tablet as i use it daily for work..

Why it does not read the SD card? I would expect that should work and should be the safest bet here...

-Maybe the zip file really is corrupt, which can be easily told by unpacking via pc.
-If the tablet can still charge the battery usb is most likely okay.
-Sdcards can fail by becoming read-only. Most easy to tell by unsuccessfully trying to format them in the tablet or pc , but e. g. under Windows you seemingly can successfully delete and copy stuff, everything as it should even after forced refresh via F5. But after reinserting the card or rebooting the previous state is back.
-ADB has been enabled in developer settings? Then you normally get a notification where you can modify usb mode. Charge-only won't work, but most of the rest should do (Dcim/mtp/msp...) .
-And all the time Windows has to recognize the device via PnP and auto-install drivers for the current usb mode. Besides the aforementioned storage drivers for flashing and communication a modem driver and virtual COM ports must be auto-installed.
In this department i had lots of trouble with a phone based on an old TI OMAP SoC under any Windows newer than seven. Only Download mode invoked on the phone itself was still working and only zseful to restore stock rom, while in the more flexible Fastboot mode the phone wasn't recognized by Windows.
Samsung devices seem to support Fastboot only, but call it Download mode.
To come to an end, if everything fails i'd recommend to install stock rom in "download recovery" (Fastboot?) mode via Kies. If this also fails try to put the P605 manually into Download mode (Power and Volume minus or plus), no need to press home button, as often advised. After this, work your way back to Twrp, custom rom and root.

@crwzar80
Try connecting the tablet to a Windows 7 PC/laptop, making sure it's on an Administrator account (so it can autoload/download needed stuff). Not Windows 10 or even 8.1, but Windows 7.
I had the same problem a while back ago; if your attempt with this method succeeds then report back; I had an unconfirmed hypothesis about this issue.
