!I know there's a way to swap Internal memory with your SD, but i'm not a big fan of that :)!

(I know it's in French)

This will increase your acer 1GB internal storage to 1,5/2/2,5GB (Taken from your Phone memory)

It works very well, but it needs a custom recovery for the nandroid backup you need.

You need to Erase all data/cache on your Liquid E2 and you do need to set it up again as a new phone after executing it

You need to register on the FrAndroid forums to be able to download the files (Sorry nothing i can do about it, i will not link cause i don't know if the allow it)

I used it on an "Acer Liquid E2 (V370) Single Sim version, but it should work on the Dual Sim version to

1. You need "ROOT" for this

1. Be sure to have latest CWM recovery installed (I used CWM v6.0.3.5)

(If you have anything lower, use "MobileUncleTool" to upgrade your CWM recovery with the one provided on the FrAndroid Forums)

2. Reboot into CWM recovery

3. Make a nandroid backup and reboot your phone

4. Download the "AcerV370RE.apk" file from Fandroid forums and put it on your External SD or Download from here: https://mega.co.nz/#!wVp3QTIL!cAVGgnLW2mNTMLyIz9MBCGnparYnQ1ZsDc5N64gbM3Q

5. Install it BUT DON't execute it yet

6. Turn off your phone and take out your External SD (Or unmount your External SD cart and take it out)

7. Execute "Acer V370 Rom Edit" (The installed AcerV370RE.apk)

8. Choose your option:

- Partion Stock (1GB) -> Default size of 1GB

- 1,5GB

- 2,0GB

- 2,5GB

- Partion Stock (1GB) -> Default size of 1GB (I don't know why it is shown 2x)

You have to figure out yourself what's best for you, after some testing i did go for the 2,0GB option and that turns out very well

(When you don't want to do it go for "Sortir" (Exit))

09. After you have decided what option to go with press "OK" to confirm it

10. When it's done, choose "Reboot en Recovery" and confirm with "OK"

11. Your phone will now reboot into CWM recovery

12. Wipe cache partition

13. Wipe data/factory reset

13x. Go to advanced and Wipe dalvik cache (Not really needed but i did it to be sure)

14. Reboot system now

15. Now choose your language and setup your acer like a new phone, you don't need to set up a Google account, just skip it and skip the acer Registration stuff to. Once you are on the main home screen go to settings and storage to check your storage, if you did go for the 2,0GB option your screen shoul look like this:

Screenshots are taken after i put back my Nandroid backup! I did set the language to English for it instead of Dutch/Flemish) ;)

Don't mind the "Total Space 2.35GB" showing, whatever option you choose, it will always show this!

16. Reboot into CWM recovery again and restore your nandroid backup

17. If everything did go well, you should now have everything back as before and a working Acer Liquid E2 with 2GB internal storage instead of 1GB

Hope you understood my quick English explanation

Messing around with this can be dangerous, I and Anyone else are NOT responsible if you screwup!

You don't need to do it, that's your decision and yours only! I only provided an English translation!
