Sorry, noob alert:
I'm on rooted 4.1.2 still
I have CW v6.0.1.2. I'm currently making a CW backup to my external SD card. Once finished I hope to copy that backup to a PC.
After that's fiinished I should wipe everything in CW including cache, dalvik cache, data, sysytem, internal storage.
Do I then take the move the MOAR_V7.1.0 file to my external SD card and go back to CW and select that .zip file to update the phone and that's it? What about this MK3 Modem file?
Sorry for all the noob questions but back when I rooted the phone I just followed a qbking youtube video and that was easy as pie. Now there doesn't seem to be a complete instruction on how to do this and I don't know what I'm doing.
First you need to flash a new recovery, can find the latest touch CWM 6.0.4.3
here. Boot into recovery, wipe cache and dalvik then flash the zip. Then reboot.
Then you need to put the phone on the 4K3 Modem,
here is the flashable file. Same procedure as before, boot into recovery, wipe cahe partition then dalvik then flash the modem file.
After you have done that you should be able to flash
MOAR 7.1. Follow the instructions on the MOAR page, choosing option 1 the first time. Also since you are now flashing a ROM you will boot into recovry, wipe cache, then dalvik then wipe data/factory reset. Then after that flash the MOAR Zip file and prepare to set a lot of time aside to get it up and set the way you want it.
Do you have Titanium Back UP? If so you might want to
follow these instructions to set up the apps you have now. The first post is all you need to follow.
There are a ton of options, read the MOAR thread to see what you want to choose on your second install, you will go into recovery, do the 2 wipes, cache and dalvik and then flash the MOAR zip again choosing option 2 to customize it. DO NOT WIPE DATA/FACTORY RESET THIS TIME.
Sense the theme? Every time you flash a zip for a minor change you wipe the cache and dalvik. If you are changing ROMs or performing a major update (4 to 5, 5 to 6, 6 to 7) it is best to wipe data. If you are going from 7 to 7.1 you don't have to wipe data you just flash the ROM, this is called a dirty flash, and should hold all of your apps and settings.
Before you do anything you should boot into recovery and then perform a nandroid backup, it is in the main screen > Back Up and Restore. Take notice to which back up option you choose, to the SD Card or the External (SD Card1), if you need to run the backup you enter the same menu and choose restore from and it will put your phone to the exact state it is when you did the backup, so if you screw up you can always restore your phone to a known working state.
I see you did a backup in your post, that's good.
