hi guys
i am going to make a guide for how to make a custom rom for yourself without a pc.
so straight forward first check that you have following things.
1--> a android device (rooted)
2--> clockworkmod recovery installed
3--> 100% battery
4--> atleast 1.5 GB free on external SD card
BEFORE STARTING THIS METHOD I RECOMMEND YOU TO TAKE A PRINTOUT OF WHAT THIS GUIDE SAYS BECAUSE YOU HAVE TO DO WORK WITHOUT A PC ON A NON MULTITASKING ANDROID AND LOOKING TO XDA SITE OR APP EVERY TIME IS NOT A GOOD IDEA.
STEP ONE :>
First of all move all your data on internal sd card to external one and then do a factory reset.
After that goto recovery mode and follow
wipe data
wipe catch
backup and restore --> backup.
after having a nandroid backup. turn on the device normally. and just install es file explorer(it is good and provide lots of options).
STEP TWO :>
now you have a nandroid backup. goto that folder and open it. there are many files and one of them is system.******* . now copy that to a new folder where you will make a rom and paste it {remember to copy only do not cut or disturbe the original copy in backup folder just copy it}.
in the new folder look at the name system.*** you will get the original extension of that file its either .rar or .tar or.zip
now rename it as system.(the extension you found)
after renamming it just extract it and you will edit in this folder to make a new rom.
STEP THREE :>
in that folder you will see many folders just have a look at all folders and write names of those folder which have .apk files in it on paper. now those folder which have apk files are to be edited.
THERE ARE TWO TYPER OF ROME
1--> DEODEXED {HAVING ONLY .APK FILES IN THOSE FOLDER}
2--> ODEXED {HAVING .ODEX FILE WITH .APK FILES IN THOSE FOLDER}
DESIDE WHATS YOUR ROME TYPE AND FOLLOW THW GUIDE SERIOUSLY
FOR DEODEXED ROM --> now you have to give shape to your rom. i will provide you with list of apps you can change in custom rom.
launcher
gallery
camera
lockscreen
keyboard
calculator
gapps
internet brouser
file manager
you can add special apps to your device like screen recording software
and remove the default apps listed above {first remove default app and then paste the app you like}
FOR ODEXED ROM --> now you have to give shape to your rom. i will provide you with list of apps you can change in custom rom.
launcher
gallery
camera
lockscreen
keyboard
calculator
gapps
internet brouser
file manager
you can add special apps to your device like screen recording software
and remove the default apps listed above
first delete the app and its odex file and then past the new app{if you leave odex there for default app the new app wil be transformed to older once so delete odex of only those apps which you cange}
STEP FOUR :>
now you have apps of your choice and you are exited to test it.
but now its time for trickest part editing build.prop in system
inside system folder you extracted there is a file named build.prop open it and start editing
#change lcd screen density
ro.lcd_density = {increase for magnified view and decrease for a zoomed out view}
#change ram alootment to apps
delvic.vm.heapgrowthlimit = set only one value {68, 96, 124 ,256} {set a higher value than default in your file}
delvic.vm.heapsize = ste higher value than heapgrowthlimit, set only one value {96, 124 ,256} {set a higher value than default in your file}
#to get navigation bar at the bottom with three icons
qemu.hw.mainkeys = 0
save these changes {these lines are not to be edited they are there in that file only change the values ok}
STEP FIVE :>
copy the nandroid folder onto pc and save a copy of that nandroid backup on pc.
YOU HAVE MADE A CUSROM ROM BUT IT CANT BE FLASHED SO NOT GOTO THE SYSTEM FOLDER WHERE YOU EXTRACTED IT AND SELECT ALL FOLDERS INSIDE IT AND MAKE A SAME EXTENSION FILE WHICH YOU EXTRACTED IT FROM {select all folders inside system folder and make same extension file do not just select the system folder from outside go inside the folder and then do that ok}
for this step you will need a pc ofcoz.
STEP SIX :>
GREAT JOB YOU HAVE A SYSTEM.XXX RENAME IT LIKE THE NANDROID BACKUP ONE AND REPLACE THE ORIGINAL SYSTE, FILE WITH YOUR MODDED ON AND JUST CROSS YOUR FINGURES.
all steps are complete and not its time to reboot to recovert
wipe data
wipe catch
advance/wipe delvic catch
backup andrestore/advance restore/restore system
and its done first boot will take time and you have a custom rome made for yourrself on android and time to test it.
remember if you face any problem just use that nandroid which you saved on pc the original one and restore that to go back to custom rom.
