HOW TO USE “ADB SLIDELOAD” METHOD TO MANUALLY UPDATE NEXUS AND OTHER ANDROID DEVICE
Well there may be a case that you don’t receive any OTA update notification for an update ( even it is released for a long time ) in that case you need to manually flash the update package file on your respective device which Google release normally after an update everytime. Today I will tell you how to use “adb sideload” method to manually update your device without rooting or using custom recovery

It is “STANDARD” guide, which can be used on any Nexus device like Nexus 5, Nexus 4, Nexus 7, Nexus10 and other device to update it manually.

I am considering that you are on stock android ROM and have unlocked/locked bootloader.

NOTE :- No need of Rooting or custom recovery in this process. In recovery “volume buttons” are used to navigate and “power button” to select.

You must have the latest version of “adb“. Download it from given below link and then extract on your PC.

Download https://drive.google.com/file/d/0B2ONZFOkl3m7R2tQM2lGV1N3T00/edit | 1.10 Mb

Download the respective OTA package of your device ( ex like OTA.zip ). Rename the file as “update.zip“. Place it in same folder “Platform-Tools” as where “adb” is placed.
Enable USB Debugging on your device, to do that go to settings >developer options > enable USB Debugging. After enabling it, connect your device to PC.
Now navigate back to same folder “Platform-Tools” and in above folder directory path type “cmd” and press enter option.

Command Prompt box should open now, Is it ? If yes, proceed below…

use adb sideload method to manually update Nexus device

Type “adb devices”. You will see your device listed on the command prompt screen as shown below.
Type the command “adb reboot recovery“.

Rebooting Nexus in adb recovery mode

Your respective device will now reboot in recovery. Device reboots, see Google white logo ? Yes, good.
As device reboots in recovery you will notice an android laying down with a black exclamation mark inside red logo and “No command” written below it, exactly at that moment “press power and volume up button together” and release them. Now you are in stock recovery of your device. List of four menus will be displayed.

Menu Appears ? Yes, then select “apply update from adb” by using volume down button and press power button to select it.
Now in your PC’s command prompt box, type command “adb sideload update.zip“. This will load the file and updating process begins.
As soon as update finishes reboot the device.

Note :- To avoid the error of “adb sideload device not found”. As when connected your device to PC after enabling USB debugging, Navigate to “Platform-Tools” folder and open command prompt and type command “adb devices“, if your device is successfully connected you will get a result like your device.

What if installation fails ?

If installation of update.zip file fails in sideload method then don’t panic, just press power button for a while until device turns off and then press again to reboot it normal mode.

I will sincerely hope that by following above steps you will be able to successfully update your device. If you are stuck on any step, just leave a comment we will help you out.

Drop your comments below if you need any help regarding updating your Nexus device manually by using adb sideload method, I will surely help you.

ENJOY!!!

ee this shoe charges
your Android/
smartphone when you
are walking

The mechanical engineers at the
University of Wisconsin-Madison,
made this new energy harvesting
and storage technology
developed. This technique can
reduce reliance on batteries in
mobile devices and charge your
smartphone as you walk.
Tom Krupenkin, professor of
mechanical engineering, and
senior scientist J Ashley Taylor
described the innovative energy-
harvesting technology that can
capture the power of human
motion to charge mobile electronic
devices such as smartphones and
laptops.
This could enable a footwear-
embedded energy harvester that
captures energy produced by
humans during walking and stores
it for later use.
Power-generating shoes could be
especially useful for the military, as
soldiers currently carry heavy
batteries to power their radios, GPS
units, and night-vision goggles in
the field. The advance could also
provide a source of power to
people in remote areas and
developing countries that lack
adequate electrical power grids.
“Human walking carries a lot of
energy. Theoretical estimates
show that it can produce up to 10
watts per shoe and that energy is
just wasted as heat. A total of 20
watts from walking is not a small
thing, especially compared to the
power requirements of the
majority of modern mobile
devices,” explained Krupenkin.
Krupenkin and his colleague J.
Ashley Taylor believe that this
technology could be a game-
changer in the energy space that
could power a wide range of
devices from your phone to your
tablet to just about anything that
requires batteries for operation.
A typical smartphone requires less
than two watts of energy.
“We have been developing new
methods of directly converting
mechanical motion into electrical
energy that are appropriate for this
type of application,” Krupenkin
noted in a paper published in the
journal Scientific Reports.
The team has been working to
develop new method of converting
mechanical energy into electrical
energy that would work for
generating power from a human
walker. The process the team is
working on now is known as
reverse electrowetting. This
technique uses a conductive liquid
that works with a nanofilm-coated
surface that is able to produce
electricity.
Researchers developed a ‘bubbler’
method, which combines reverse
electrowetting with bubble
growth and collapse. A bubbler has
no moving mechanical parts and
uses a pair of flat plates with a
conductive liquid between them.
The tiny holes in the bottom plate
allow pressurized gas to enter and
form tiny bubbles. The bubbles
grow until they are large enough
to touch the top plate, which
causes the bubble to collapse.
The speedy, repetitive growth and
collapse of bubbles pushes the
conductive fluid back and forth,
generating electrical charge. This
method produces around 10 watts
per square meter of surface and in
the space of a shoe; the team
believes that making 10 KW of
power might be possible.
The findings were published in the
journal Scientific Reports.
The engineers are looking for
industry to commercialise the
technology through their startup
company, InStep NanoPower.

How to unbrick hard bricked android phone (all Android
phone)

This is how you can get back your hard bricked device.
Well let me explain what it means when you andriod phone get hard
bricked. your phone behaving like, not able to boot it to recovery

you will get your phone back to speak.
Before going for unbrick process we needed some tools to setup
environment for phone.
•• ADB (Android debug Bridge) Tools click here to download
•• Stock ROM ( ROM that has system.img, cache.img, recovery.img &
boot.img ) of your android device.
Don't worry you can get Stock ROM for your device very easily just
type stock rom for XYZ mobile on google and you will get your ROM
because gnerally all stock ROMs come with system.img, cache.img,
recovery.img & boot.img.
•• USB cable.
•• Computer
•• Mobile phone USB Drivers.
by connecting mobile without battery to PC generally installed all
required drivers. If not don't panic search on google for USB driver of
your mobile.
Okay that's all we needed to setup environment for unbrick process.
Now we can start to unbrick our android phone. Follow my steps........................
•• Extract all files from ADB tools. Open the ADB Tools folder on your
PC. Now go to adb-tools_driver > adb-tools_driver > adb-driver and
run the 'UniversalAdvDriverSetup' install file.
•• When the installation is finished, make sure that Fastboot is in the
ADB Tools folder. If it isn't, download Fastboot for Windows.
•• Restart your phone in Fastboot. To do this, turn it off, then press
and hold Power and Volume Down until you see the Fastboot menu.
The phone should still be connected to the PC with the USB cable.
If phone not going to Fastboot mode than connect it to PC by USB.
Hold Volume Up and Power button until you get company logo or
backlight.
•• Open a Windows Explorer window and head to the ADB Tools
folder.
•• In a blank space in the window, hold Shift and right click your
mouse. Then click on Open Command Window Here.
Type the following command:
adb reboot fastboot
You will get your phone in Fastboot mode. Now follow these steps.
•• Copy all .img files from root of stock ROM to ADB tools folder.
••Type following command to clear everything.
fastboot -w
•• Now flash every image file one by one by using this command.
fastboot flash
< > will replaced with partition name and file name don't worry partion
name always same as file name without extension. For example you
must need to flash these partition.
fastboot flash boot boot.img
fastboot falsh userdata userdata.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash system system.img
•• In the end just reboot your device by using following command.
fastboot reboot
•• Now unplug your phone. It will take some minutes on bootscreen
don't worry wait for some minute you will get your phone unbricked.

Latest WhatsApp build reveals Facebook linking option

When Facebook bought WhatsApp for $19 billion back in 2014, every person connected with technology
had only one question. Why did Facebook buy WhatsApp? There was no possible reason for Facebook and WhatsApp merging on as single platform but there were a log of areas in which both
were converging. Slowly and
steadily Facebook is working on converging both Facebook and WhatsApp together.
A new leak about the upcoming WhatsApp build reveals that WhatsApp will now allow cross
communication between Facebook and WhatsApp accounts. When
messing with root commands, version 2.12.413 of WhatsApp shows
the option of linking a WhatsApp account with a Facebook account to
“improve Facebook experiences”.
While the actual use of this facility is not known, it may be that WhatsApp may allow users to cross post on Facebook through their
WhatsApp messages. The actual use of this linking of Facebook may be known only when the actual build is released to users.
However, one thing is certain, in future a WhatsApp user will be able to post simultaneously on his/her
WhatsApp timeline and Facebook.

WhatsApp, which is already the world’s largest cross platform messaging App is reportedly working on providing ‘Skype’ like video calling facility to users, dropped its subscription fees
earlier in the week.
