hi Vanessa Hana and recom where we get on Android everyday anyway today we're
gonna go ahead and learn how to install a new custom ROM off for this example
I'll be installing cm-12 also this will be a fail proof method so
hopefully you'll be able to install it the first time instead of the second
time or ending in a boot loop you know I've realized over the years that
formatting system is necessary for good insulation usually you just do you know
factory factory reset in the install ROM that doesn't format system and sometimes
when you install roms like silage and mod 12 or CM 11 or any of the USP roms
sometimes what happens is you install the ROM and you end up in a boot loop
and you have to format the system anyways and do this second time so in
this tutorial I'll be giving you a universal method on how to install ROM
and make it boot the first time before we do this make sure you make a backup
rom before you do it also will be using TWRP recovery of to do this you can also
use CWM clock Ramon recovery I'll have another video with that but the
instructions are pretty much the same just the menus are slightly different um
so let's go ahead and install cm 12 on my t-mobile note 4 also this again this
will this is universal method for all kinds of Android devices whether you
have a note 3 HTC One Nexus 5 Nexus 6 if you have tore recovery installed um you
can follow the same exact method to install the rom um so let's go ahead and
do this baby alright before we begin you should have
downloaded the rom zip file off straight to your phone or you can download to
your computer and copy it over if it's a large file
I do recommend make sure you have stable internet download on your computer and
copy it over if you don't want the rom file to take up space you can also
download it on to a USB flash drive here use an OTG cable
that's a good way to or you can just download it install the rom and then
erase the rom zip file you don't need it after now roms like cm-12 will actually
have they'll actually have a separate file for the Play Store in your google
apps which is called G apps so make sure you download that too if you're
installing cm 12 or CM 11 or any of the signage and mater any AOSP roms i'm so
once you have downloaded onto your phone let me go ahead and show you a verify
that you have the files downloaded alright and here we go and you can see I
have cm 12 there alright I'll actually know what I have it in my other storage
sorry I put you can put in your internal storage your microSD card or you can put
it in your TG flash drive there we go cm 12 in G apps that's all I
need now sometimes these zip files are bad so let me go ahead and show you how
to do that what you'll need to download is the sinkhole ES File Explorer app and
this will show you if the file is good or not you can also check the md5 or
just a simpler way you know is just download ES File Explorer that way you
don't have to check the md5 now all these rom zip files are in zip files do
not under you download it if you download on your computer copy the whole
zip file onto your phone you can also check the integrity of the zip file on
your computer just see if you can open it if you can actually open the file to
unzip and that means the file is ok that way we can go ahead and bypass the md5
checking the md5 of the file there we go so let me go ahead and open it and go
ahead and go ahead and go ahead and go ahead and find the file so if you keep
clicking here it'll probably show you the file it's in alright and if I plug
this in it should also show you my USB storage sharing couple seconds alright
let me go ahead and show you its the file here oops there we go
so let me go ahead and do this there you go now you see USB Drive if you're using
USB Drive you can do that also go ahead and find the zip file the roms if I you
download it all right and it's in my download and you can see this file here
let me change the view to make it like that if you actually click on the zip
file and choose a easy viewer and you can actually open it like this which is
the which shows a contents of the file that means your file download is ok so
if it doesn't install don't blame it on the file download that's great alright
because a lot of times people you know get into they install the ROM and it
just immediately fails and the first thing I asked them is you know is did
you download the file is that ok is it you know is it bigger than 0 bytes
sometimes it downloads as real bytes um so this is one way you can check it
also the G apps let me set this as default you can see it opens so these
two files are good to go now once you have good files we are ready to go to
the next step um so for let's reboot into recovery and
I actually don't need this I'm actually not using my micro USB flash there um go
ahead and you can use a quick boot app you can get on the Play Store alright
dunno root access um so for some reason my I don't have root access but if you
do have root you can go ahead and simply select recovery here and they'll boot
you into recovery now if you don't have for root for some reason and maybe you
just installed for up on top of your stock recovery with the Samsung phone so
you can go ahead and hold down volume up Center home and the power button for
about 5 seconds or 3 seconds and if you see recovery booting you can go ahead
and let go the buttons now if you're using Nexus devices or HTC One its
volume down and power hold it until as you see the bootloader menus and then
choose recovery and hit the power button and then you should be in torque if you
don't see this that means you don't have TWRP recovery installed you might have
something else like clock my recovery which instructions is pretty much the
same if it's a CW or Phil's recovery at the top but if you
see like green Android guy with just four menus or five menus
that's stock recovery you don't even have any kind of custom recovery um so
if that's the case you'll have to install twrp recovery you know let's go
ahead and install this problem so this is the fail proof method in my opinion
so the first thing you should do is go to wipe and don't do the factory reset
go to advanced wipe all right and then do wipe system data dalvik cache all
right like that oh and cache also this way you're
actually formatting system the regular factory reset only formats data dalvik
cache in cache you should actually really format the system also now wiping
your system data dalvik cache and cache this will erase everything on your phone
except your personal files and videos so all your settings all your apps all your
app data is going to be Oh gone zip so at this point if you did not make a
backup ROM abort this go back home and hit the backup button otherwise we're
gonna go ahead and wipe dalvik system data and cache all right and we're gonna
go ahead and data it to wipe if you've made a backup bomb you can always
restore your ROM which is out here all right
formatting system all right unable to mount storage don't worry about that
sometimes you get these errors or some of these sometimes it's like a bug or
something but it works just fine all right and then we will go to install and
then go ahead and choose these stores you're gonna use for me it's in micro SD
card if you download it straight to your phone it's most likely in your internal
storage and your download folder but I didn't so I'm gonna go to my micro sd
card download folder I'm going to choose cm-12 alright I'm gonna go ahead and do
that and this will install the rom now some roms they come with this thing
called aroma graphical installer and what that is is basically it gives you
options graphical options that you can do a whole bunch of
stuff so go through that and install it if yes that's the case but if it's not
it's just a successful when it's done it might take you longer I have a note for
if you have like an ode to might take like 20 seconds alright go back home and
go ahead and go back to install if you if you're installing like a cm-12 if
you're installing in just a regular rom that does not require g apps and you can
go ahead and just reboot but this one requires it because it's Asus I know gen
mod 12 ROM and confirmed to off flash G apps Google Apps and that's pretty much
done home and reboot now the only thing we did different instead of doing the
standard wipe which swipes data cache Dalek went to advanced wipe and added
system that usually you know makes everything correct and I found out that
one out of every 10 flashes it fails if you just use a regular so this way it's
more more or less fail proof and we'll go ahead and reboot the system and you
know some of you were like why don't you like clean the fingerprints off your
phone before you make the video well yeah there you go now you don't have to
troll there we go and hopefully it works but I'm telling you this method
formatting the system usual boot and 99% of the time the questions I get is this
because they didn't format system I tell them to format system and reinstall the
rom and then sometimes people don't know how to do it so I made this video so to
clear it up so I don't get all these questions and so your rom boots the
first time if there's nothing wrong with the rom 9 out of 10 times in my
experience I have boot it's a custom ROM every time I've installed it but if you
don't format system like maybe like 3 out of 10 times you'll fail boot loop
especially if you're going from like a TouchWiz ROM to CM rom or our sense rom
to a CM route we're back and forth one of the reasons that I can say
for those of you interested is because the file structure may be different and
if you don't format system sometimes it gets corrupted while you're switching
between those type of different rums but this way everything just cleared off the
system and it's it's just like formatting your hard disk before you
install new windows or something so that's what we did and it should boot up
here in sec and usually it should cm-12 actually takes a really long time see
I'm 11 like the older Kit Kats they'll boot up pretty quickly this one
takes sometimes five minutes so I will be back when this boots up completely
and boom Shakalaka my rom did boot after about two minutes depending on the phone
you have if you have a fast processor it's gonna go faster
alright so I'm gonna go ahead and go in here
meaning skip anyway but as you can see I wasn't able to install it from a
TouchWiz to cm-12 on my first try um so this should help you as long as you see
the welcome sign you should be good to go and you can see I'm already picking
up data I'm good to go and I've got my Google Play Store
everything working out of the box I'm so that's how you can install a custom
realm now this is a universal method for all kind of rooted android smartphones
tablets and also should work for all all kinds all types of different realms so
if you're always asking some people ask me like you know if I introduce a new
rom like cm 12 from like max how do you install cm 12 it's the same method
they're all the same method you know so I just want to make this one video for
all the different phones so that way I don't have to make it again all the runs
are exactly the same how you install it but I only show you a little trick a
formatting system will guarantee usually a guarantee like 99% of the time your
rom will boot the first time and yeah I hope this video has helped you and
thanks guys for watching this video with this video should help you install your
favorite custom ROM in just one shot now if
you end up in a boot loop 99% of the time that roms probably bad or
something's up with your bootloader it doesn't match the ROM you're installing
you know you can go ahead and try this method maybe like two more times and if
it doesn't move it's the roms fault or you have a wrong move loader for the ROM
other than that your rom should be booting and you should be on your new
custom ROM anyway thanks guys for watching this video as always don't
