This project has been on my mind for sometime now, and I finally got around to free up some time to look more into it. My first attempt was to just install a different boot.img, but that just wasn't going to happen. The whole reason for this project was to make it easier for one to downgrade and revert in between the 2 different Base versions without the use of having to hunt down the PC to fastboot or RSD. I have used both zips which in turn allowed me to revert and downgrade through TWRP so I could install source built roms, stock based roms and also restore TWRP backups from both bases. After heavy testing I am releasing this to the Unlocked community so you may have more choices to use without needing a PC by your side. I created 2 different installation zips that install through TWRP Recovery. One is to be used to downgrade your current 4.4.2 system to be able to install 4.1.2 based roms. The other will basically revert those changes so that you will be back onto the 4.4.2 base system. Both come with there matching updated TWRP recovery programs for the base that it will be used on. Also a Slightly modified boot-logo will replace your current one, If you still have the unlocked bootloader warning you are welcome and if you have a favorite one that you use you can always unzip these and replace the logo with the one of your choice. Installation Instructions below must be followed so that everything will fall into play. Please Read, Read, then Read again. I have used this multiple times to get it setup so that one will not have issues while using this. So if you don't read just put the phone down and step away........

Thanks in Advance.

 

 

 

To the Testers that got to use this before you did

and put it through the hoops to make it easier to

use for you.

To Jay and Teamlightspeed.com for server space

To Droidrzr.com.......

And yes to that tech at Motorola that made the

mistake....Much Thanks.

 

 

 

Before Starting this I must advise backing up what is on your internal storage first. Why you ask, well Moto thought that they wanted to change the format of the data partitions. The data/cache and data/data partitions are fine as they get changed when you do the Factory reset before flashing, but some testers had issues accessing data/media which is the internal emulated storage on the first install of FlashBack to 4.1.2. The processes only has to be done once so that when you are downgrading and reverting you won't have issues accessing the internal storage.

 

FORMATTING INTERNAL STORAGE

Back up what ya got on the current ROM you are on YOU WILL LOOSE EVERYTHING IF YOU DON"T

Boot into current TWRP 2.8.0.0 then go into wipe settings then press Format Data. You will be given a warning and will have to type the word "yes" in order for it to proceed. Once this is done it is done you will not have to do this any longer. Boot back into the ROM that you are currently running and transfer back over the content that was once on your internal storage.

Great work Charles, this will be very useful. Thanks again.

[nobe1976]

Can we now flash JB and KK ROMs with TWRP 2.7.1.0 with this? 

[nobe1976]

Your one of those that scan through the OP huh....... 

 

This is going to switch you Base and TWRP on the fly. The FlashBack to JB will install TWRP 2.7.0.0 that will allow you to properly prepare your device to install a rom off of that base.

Can we now flash JB and KK ROMs with TWRP 2.7.1.0 with this? 

 

If you flash the JB flashback then it installs the JB bootloader and whatnots and TWRP 2.7.0.0 and you can flash roms built for the JB bootloader. IF you flash the KK flashback then it installs the KK bootloader and whatnots and TWRP 2.7.1.0 and you can flash roms built for the KK bootloader

Thanks you so much for this my good sir much appreciated!

EDIT: Hi im not sure if you can advise me. Im trying to backup my data folder, but it says google wont allow me to do it, (using RES file explorere) Do i need another program to do this to bypass the google blockade? It says if im rooted (which i am) i can perform all these functions, but it just wont do it x.x

 

EDIT: it seems i misunderstood something, but everything is ok now, thanks again!

Ive tried to zip it then move the zip, but at the last stage of compression it just seems to loop on itself x.x

 

Google shouldn't be blocking it. Try hooking it up to your computer via USB and copying it to your PC

Worked great, but for some reason JB based ROMs wouldn't connect to WiFi... it would detect the network, and upon hitting "Connect" nothing would happen. I tried Validus 6.0, Paranoid and the CM11 M8 Snapshot... all the same issue.  :

 

EDIT: Nevermind... I'm an idiot.   Great tool!

Yeah that would help out too 😚

[thewraith420]

Do you plan on putting this on XDA or mind a link over there? It really is handy to have on my sdcard

[nobe1976]

Me personnaly would rather keep my Download links here. Just like my Omni Rom. If you would like to create a tread over on XDA then by all mean I cannot stop you, but make the Download links point back ro this tread. Much appreciated.
