[General Questions and Answers] AndroidOVERALL:
Ok so here are the files and the process for restoring the DELL STREAK 7 WIFI ONLY using NVFLASH. This post is a collection of the info I used to restore after I went to DJ_Steves ROM but forgot to do a NANODROID backup.

AGAIN THESE ARE THE WIFI ONLY FILES!

Thanks to:

for the detailed NVFlash procedure.

solidsnake66

for uploading the stock wifi files.

Chemus

for the altered restore.bat file

Follow these steps and you will be back to stock.

If for some reason it fails post details of what went wrong or search the forum based on what failed for you and I assure you there is a answer out there.

I am not responsible for any damage caused by this process.

If you need to do a factory restore of any kind it will not work if your battery is below 50% so make sure your battery is charged before you start this process!

Restoring the Streak 7 using NVFlash

(Windows Only Instructions) If you’re a Linux user, you should be able to 'translate' this yourself.

This is for those who cannot use fastboot or adb. If you can successfully use these tools, DO NOT use NVFlash. You will lose all your data on your device. Do not proceed with these instructions if you are not expecting to lose all personal data on the device.

Step 1) APX Drivers – To work in NVFlash mode you need to install the drivers for the nvidia boot-recovery device. Power off your device and disconnect it from the computer. Hold down the Volume up & down buttons while plugging in the USB cable. (Or leave the USB cable attached and hold the pinhole ‘power off’, hold down the volume Up & Down and release the pinhole ‘power off’.) (The volume button seems like a rocker switch, but you can hold down both sides at once)

Your computer should now recognize the Streak 7 as an APX device. Manually install it using the nvidia boot-recovery drivers.

Step 2) Install NVFlash. For ease of function simply create a folder on your C:\ drive called ‘nvflash’. Download the nvflash zip and extract it to the nvflash folder.

Step 3) Download the stock wifi files here: http://www.multiupload.com/96WH2O4OCD (Takes about 30 minutes. Use direct download via multiupload NOT THE DOWNLOAD FILE VIA RAPIDSHARE) Put these files in the C:\nvflash folder.

Step 4) Open the restore.bat file and delete everything from it. Then copy the following into that file:

.\nvflash.exe --bct flash.bct --setbct --bl bootloader.bin --configfile flash.cfg --rawdevicewrite 0 1536 p2.img --rawdevicewrite 1536 256 p3.img --rawdevicewrite 1792 1024 p4.img --rawdevicewrite 2816 256 p5.img --rawdevicewrite 3072 1024 p6.img --rawdevicewrite 4096 256 p7.img --rawdevicewrite 9216 8192 p8.img --rawdevicewrite 17408 8192 p9.img --rawdevicewrite 25600 8192 p10.img --rawdevicewrite 33792 172032 p11.img --rawdevicewrite 205824 57344 p12.img --rawdevicewrite 263168 8192 p13.img --rawdevicewrite 271360 286720 p14.img --rawdevicewrite 558080 1048576 p15.img --rawdevicewrite 1606656 8192 p16.img --rawdevicewrite 1614848 8192 p17.img --rawdevicewrite 1623040 8192 p18.img --rawdevicewrite 1631232 8192 p19.img --rawdevicewrite 1639424 8192 p20.img --rawdevicewrite 1647616 8192 p21.img --rawdevicewrite 1655808 6103040 p22.img --rawdevicewrite 7758848 8192 p23.img --rawdevicewrite 7767040 8192 p24.img

Save and close the restore.bat file.

Step 5) Unplug your streak from the computer and power off. Hold down the Vol up and Vol down buttons and then plug in the usb cable. Your computer should recognize your device. (Note if you already left it in this state from Step 1 you do not need to do it over again.)

Step 6) Launch (double-click) the Restore.bat file from the C:\nvflash folder. This batch command will begin copying the partitions to the device. Wait patiently as your device is being restored. This will take anywhere from 30 minutes to an hour. Just be patient as it is worth it.

Once the comand prompt window disappears that means the process is complete.

Power on the device. It will take a while to load so it will stay on the dell logo. If after 5-10 minutes the dell logo is still there use the pin hold next to the sd card to power off the device.

Do a factory restore by holding down the volume up button and the power button. This will bring you to the screen where you can do a factory reset. One will be user data only and the other will be user data and internal and external tablet storage . When I did this I personally had to do both for it to work.

Finally check to see if you are still rooted using gingerbreak. If it gives you the option to unroot then unroot. Some people have had success with just the process above others still have root access after the process. Double check using gingerbreak.

********* ONLY PROCEED IF AFTER YOU COMPLETE THE PROCESS ABOVE YOU STILL HAVE CWM RECOVERY INSTALLED WHEN ATTEMPTING TO DO A FACTORY RESET ON USER DATA AND INTERNAL AND EXTERNAL TABLET STORAGE *********

So I had a buddy of mine tell me he had an issue where he was unable to get CWM Recovery removed as it still showed up when he attempted to do a factory reset.

So I did the unthinkable and rooted my device and flashed CWM recovery to my DS7(WIFI ONLY). I was unable to get it removed. I tried going to DJ_Steves ROM and I tried flashing back to stock with the process above, NO LUCK! Well about 8 hours later I finally have it figured out. I assume many people will have CWM recovery on their system and would probably run into this same issue so I did the hard work for you. Please read below:

Please continue at your own risk as I am not responsible for bricked devices or any other issues that may come from the following process.

Step 1) Download the two files below and extract them to a folder on your desktop. If possible extract them to a new folder with the file names "NVFlashStep1" for the first file and "NVFlashStep2". This ensures you execute the correct files in the correct order.

NVFlashStep1:

NVFlashStep2:

http://www.multiupload.com/8R43CZ3GCC

Step 2) Power off your device and ensure the usb is disconnected from the computer. Hold down the Vol. Up and Volume Down buttons at the same time while plugging the usb cable back into the computer. The computer should recognize your device.

Step 3) Open the "NVFlashStep1" folder and click on the "restore.bat" file. This should bring up a cmd prompt window and the files should begin to transfer. The cmd prompt window will disappear when the process is complete.

Please be patient as this will take anywhere from 40mins to an hour or more depending on the speed of your usb.

Step 4) Use the pin hole next to the sdcard slot to turn the device off. Hold the Vol. Up and power button to enter recovery. Select factory reset(User data and internal and external storage.) This should bring you to the recovery menu where you can only hold down power to do a factory wipe or hit Vol. Up to power off. If this is the case then you are ready for the next step.

If for some off chance you don't get this screen and you still get booted into CWM recovery then make sure you completed all steps correctly as this has been verified numerous times on two separate devices.

Step 5) Open up the folder "NVFlashStep2" and click the "restore.bat" file. The files should begin transferring over.

Now this is where your patience will be NEEDED. This process can take anywhere from 1-2 hours depending on the speed of your usb. So make sure you are prepared and ready to wait around.

The cmd prompt window will disappear when the process is complete.

Step 6) After everything is completed...Use the pin hole button next to the sdcard slot to power off your device. Then simply hold the power button down until the dell logo appears. The first boot may take 3-5 minutes.

- If it takes longer simply go into recovery by hold the Vol. Up and power button and selecting factory restore(User data and internal and external storage) this should bring you into the recovery menu where you can only hold down power to do a factory wipe or hit Vol. Up to power off. Hit the power button and wait for the factory wipe to finish.

- Once completed reboot and you have a stock Dell streak 7 wifi only no CWM recovery, no root, just plain old stock.
