[Dell Venue] Isrks:
first

sorry for the late reply.

In the dell's opensource page there aren't files for the 3730 (i don't know why)

but, may be i'm wrong, there aren't tutorials for flashing in fastboot, i only found posts in xda's dell venue general forum.

i'll write here a guide if you still without founding a tutorial and for any others if found this post

you need:

intel usb drivershttps://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices , read the instruccions if you are in windows 8 (i'm on win7 so i cannot tell you if is the same method or not)

The tools for fastboot (there are in a folder called "google") is a little confused so better download [MENTION=4821597]social-design-concepts[/MENTION] miKIT_BATCH HERE (before continue let's say thanks to [MENTION=4821597]social-design-concepts[/MENTION] for his useful tool that also works for root :D ),extract wherever you want in your computer.

the files to flash HEREdownload the package for your device and once donwloaded extract where you want in your computer

NOW FOR FLASH

1.-

Install the intel android usb drivers, if you did this before, skip

2.-

Open the myKIT_BATCH folder and run the "runme.bat" file, then type ACCEPT, after that type 2 and press "enter" (the option 1 is for update the driver, in myKIT_BATCH's post 1 is explained) the font should be red.

3.-

boot into fastboot (press button "power" and button "volume down" at the same time) your tablet's screen will display a blue android with gears inside and below it the "droidboot" text and your device info in your device's top|left screen corner , if yes connect your tablet to pc to recognize it (if is the first time).

4.- Open a command window

after the pc recognizes your tablet unplug and plug again the usb cable, should be faster the recognicion this time.

Then in myKIT_BATCH window press "enter" to refresh, the font will become green and will display your device's info, if is going fine in the window type 4 and press "enter", will appear another window.

IF everything still going fine in the new command window type:

fastboot devices

will display your device's info

5.- let's start with fastboot

BUT first ENSURE THAT THE BATTERY HAVE A CONSIDERABLE CHARGED LEVEL

Unfortunately i don't know what happens if the tablet power off when flashing and if fastboot will work fine after so check your battery charge first

i need to tell you that the 1-4 steps are the most difficult steps (you should have at this time the rom downloaded and extracted only extract the downloaded package (the .7z file)

after this explained so let's start.

5.1.- WIPING

fastboot have some wipe commands so i will explain the 2 that i used:

fastboot erase cache

This code explains itself, you can try this code to verify that your device is connected

fastboot erase data

easy to use but powerful, this will erase app's data and also your internal storage (the 11GB that the tablet have to store files), unfortunately i used this without know and i lost 8GB of files

5.2.- NOW TO FLASH

works almost equal with the wipping commands so it's easy to explain.

let's start with system

for a easy explain you ned to open a window where the rom's files are stored in your pc and in the command shell type "fastboot flash system" and after that drag the system file (system.img.tar.gz) to the command window after dragging the file will appear in the command window the full path of the file

I.E i have a dell venue 8 3830 and i want to flash the jellybean 4.2.2 stock rom so i downloaded the Venue_8_WiFi_JB4.2.2v1.42_FLASHPKG and extract this in F:\VENUE 8 3830\stock rom folder so after type the command and drag and drop the system file in my command window will display this:

fastboot flash system F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.system.img.gz

after this the command press "enter" and you don't need to do nothing (maybe your window will turn off and maybe you try to turn on but will keep off, don't worry only let fininsh) the fastboot program will start to prepare the file for upload to the tablet and after that to flash.

this will finish in 1-2 minutes.

NOW THE BOOT.IMG

is the same way than system but faster.

after finishing flashing system (when the window diplays the elapsed time) type: "fastboot flash boot" and drag and drop the boot.img file in the command window

I.E. in my device will be like this:

fastboot flash boot F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.boot.img

press "enter" and will do the same like system prepare,upload and flash the file.

there are in the download package more file but only with BOOT and SYSTEM flashed your tab should boot

but if you want to flash the other images you need to type

for recovery:

fastboot flash recovery F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.recovery.img

and for fastboot:

fastboot flash fastboot F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.fastboot.img

for my example, for you will be change a little ;)
