    Hey All Wonderful People! Greetings.

    I need your help. Want to know what will happen if:

    1. While downloading the new OS (Not installing, downloading), if internet (Wi-Fi or 3G/4G) disconnects
    2. After the file is downloaded and the installation is happening, the phone turns off (for xyz reasons)

    Your help is deeply appreciated.

    1. No problem as the update will resume when you have signal
    2. A reboot is normal

    Thanks for your time, the wonderful person behind the name Pugs1957 :)

    However, for number 2, I've been reading on internet that the phone goes into that recovery mode with Android logo... and nothing seems to happen...

    Hi I've not experienced phone going into recovery mode after an OS upgrade. Is this what you're experiencing? If so what is the make and model of your phone?

    I think what he means on number 2 is that in the middle of installing the update, the phone runs out of battery. You know when applying an update, you see the Android mascot with a polygon thing spinning on his belly with the words "installing update"? That's what he meant. Running out of battery during that stage is a gamble. Your phone might get bricked, or might not. More likely it will. Kind of like what happens when you pull the plug on a PC in the middle of installing Windows.

    This is exactly what I mean... I also heard from someone that I can go to Kies and update it... But what's the procedure, I wonder.

    :)

    Thank you folks.

    Exactly what ChanChan05 said... In the middle of installation if the battery drains out..

    Just plug it in and it will prompt you if there is an update if you want to.

    I believe some ROMs and updates will refuse to reboot and update if there's less than 30-40% battery charge remaining. Really to prevent the possibility of running out of power during the actual flashing, and the likely subsequent bricking.

    Most Android and iPhones won't even attempt to download the update unless there is sufficient battery available. my Nexus 10 wouldn't even check for updates until it got at least a 30% charge.

    Yes, the thing for point 2 is not to put yourself in that position: don't try to install an update unless the phone is charged. No update is so exciting that it can't wait an hour, or even a day, until the phone is in the right state to apply the update.

    As others have said, many phones won't even let you try unless you have an adequate charge. If you did manage to put yourself in this position it would depend on what was corrupted how bad the situation was: most likely the ROM (as that's the biggest bit), which you should be able to fix, though there may be data loss. If you were really unlucky and it died while updating the bootloader you would really be bricked, but as the bootloader update is very quick that would be very bad luck. But it's just not worth taking chances with this stuff.
