Custom rom 4.2.2 for Acer Liquid E2 DUO

This is another build from me for acer liquid E2 DUO (dual simcard) device, and this time is using jellybean 4.2.2.

 

Here are the features :

  • Android 4.2.2 with 3.4.5 kernel
  • Rooted, busybox, fully deodexed, zipaligned
  • rooted boot.img
  • init.d support + busybox run parts
  • gps, bt, hsdpa tweak
  • phone storage and sdcard swap
  • Superuser by Clockworkmod (thanks to Koush)
  • entropy generator tweak (thanks to lambgx02)
  • Removed unnecessary and bloatware apps
  • … something i forgot to list

And here we go the custom rom :

Download : acer-liquid-e2_signed_4.2.2_jfdesignnet_080513_123229

MD5 : e00189aed67d175e0a2e1342faee8aa9

And here is the steps to flash this custom rom :

Requirement and Preparation :

  • Read this thoroughly :
    Your warranty is now void !!!
    I am not responsible if you brick your phone, get stuck in a bootloop, or if your phone grows arms and tries to kill you. Flash at your own risk!
    Please do some research if you have any concerns about risk of flashing a custom rom before continuing! YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you!!
    If you have any other objection, don’t bother to comment, just close this page!
  • This custom rom need a custom recovery to flashed into the device, if you haven’t got it, get it here : TWRP and CWM recovery Acer Liquid E2. Both are working good for this device, get it whichever you like.
  • Warning!!!, Please make sure your device is acer Liquid E2 Duo with dual simcard slot, this custom rom WILL NOT WORK on Liquid E2 device with single simcard.

Flashing Process :

The steps to flash this custom rom is pretty straight forward :

  • Download the custom rom from link above and copy it to the root of your sdcard, you may check it first with your file manager to confirm it was there. There are two sdcard storage on this device, so you must know it’s at the internal sdcard or external sdcard. I prefer you to put this on external sdcard to avoid any difficulties.
  • Boot into recovery mode by turning off your phone, hold down Volume + button then press power button, hold them both until you see acer logo on screen then release it. Wait a sec or two … then you’ll be in recovery mode.
  • BACKUP your stock rom and data using BACKUP feature, make sure you use external storage as destination because this backup is relatively big.
  • Choose Wipe Data / Factory reset and execute it.
  • Choose Wipe cache partition and execute it
  • Choose Wipe Dalvik Cache and execute it
  • Go back to main menu, and choose Install
  • It will open a list of file on your sdcard, choose the custom rom zip file that you put on step 1 and flash it.
  • After the installation completed, choose Reboot System
  • Done

Here is the result after flash :

liquid-e2-workspace liquid-e2-menubar liquid-e2-customrom-4.2.2

Enjoy 4.2.2 custom rom version on your Liquid E2 !

  • Eric Lotgerink

    Hello, i am reading this, but you are only talking about the Acer Liquid E2 and not about the DUO version (2 sims).
    Is this mod and your custom rom also usable for the E2 Duo, or just for the single sim version (E2).

    Thanks for any information and thanks for the work on the mods and roms.

    Eric

    • darn, you are right bro. There are two models of this liquid E2, with single simcard as E2 and dual simcard as E2 duo. Really sorry for this, I’m not too aware of this acer model, just like i said on the beginning, this belongs to my friend and i even already don’t have the device. Anyway, I already edit the Title so it will not mislead other users.
      I do a little research around the forums and got reply from my fellow friend that the partition is different between E2 and E2 Duo, so i think I have to emphasize on the article that this custom rom meant for E2 Duo only.
      thank you very much for your correction Eric, you’re a good man !

      • Eric Lotgerink

        Well i am glad to read this, because i am thinking about buying the DUO version 🙂
        Thanks for the quick reply.

  • Tonny Joost

    Did you add more locales?

    • my friend, what locales? you mean languages? if yes, then no, i leave locales alone, just exactly like on the acer’s stock rom.

      • Tonny Joost

        Yeah meant the languages, need Danish, but one click rooted it and now use morelocales2. I have to because of the fact that many apps run the default setuplanguage.

        • aah, i see. 🙂 Hope it runs good on yours. Have a nice day.

          • Tonny Joost

            Hi there, yes and thx for your time/effort….

          • you’re welcome 🙂

  • Tonny Joost

    Did you add more locales?

    • my friend, what locales? you mean languages? if yes, then no, i leave locales alone, just exactly like on the acer’s 4.2.1 stock rom, since i’m using that as a base.

  • Franjo

    hi, I installed your version of the rom and is working almost perfect: there is a sound glitch using music player with mp3 file.
    herr you can see what happen: http://m.youtube.com/watch?v=OuGOmitE8hQ&desktop_uri=%2Fwatch%3Fv%3DOuGOmitE8hQ

    listening to fm radio is working without any problem.

    • hi Franjo, never experience this, but i suspect this somewhat related with dts/srs sound. Try disabling them all or use different kernel with RT preemptive or low latency.
      https://groups.google.com/forum/#!topic/android-kernel/-_f5TYD16yw

      • Franjo

        thanks for the answer. tried to disable dts or to change the equilizer settings, without success. I’ll try different rom.

        • you’re welcome

        • Franjo

          changed everything I could, without success. now I’m using different firmware (Androlum 1.0.3 – 4.2.2 with Kernel 3.4.5) and it’s working without problem. I think there is something wrong with the MP3 codec, since it’s making problems with sound files based on MP3. others, i.e. original ring tones are working.

          • thanks for the info Franjo, appreciate this.
            i still wants to fix this glitch problem, maybe someday …

  • jurek

    Can You provide stock 4.2.2 rom for acer liquid e2 duo? I really need it please.

    • hi jurek, no, i don’t have it for 4.2.2
      Once i’ve got the 4.2.1 version (i search for it, but looks like already deleted from my computer), but i already create the version of mine in spflashtool format. if you want, you can get it here : http://www.jfdesignnet.com/?p=3179 (i share at the bottom of the article)

  • Taisto

    Hello! Thanks you for amazing ROM!
    I have one problem. Sound Glitch watching video or listening music.
    Can you fix it? 🙂

    • Hello Taisto. you’re welcome.
      yeah, some users (Franjo) on below comment also reported this, and this glitch issue keeps bugging me, what cause this anyway, because this didn’t happen on my friend’s device.
      I still have no working solution right now, but i’ll keep searching.

    • Sky Rider

      I’m afraid I am having the same issue. Happens within games, and even when you press the keys when you wish to call someone. (dial tones). Doesn’t always happen, but if I keep pressing the dial numbers, you’ll hear a weird sound for a few seconds.

      • Sky Rider

        I’m afraid that it appears that there’s a massive battery drain within this ROM as well. Phone barely used for a day, already below 17%.

        • thanks, but it’s hard to tell based from your report.
          some 3g signal blank spot area can be responsible for draining the battery, also some intermittent wifi signal during autoupdate downloading, etc etc.

          try to use several days, and gathered the result, if still brings you problem then you can go back to your backup rom, am i right ?

          • Sky Rider

            The phone’s internet has not been set-up yet, so there’s signal besides for calling. I still need to look further in to it.

      • hi skyrider, sorry but i don’t understand. what taisto means is glitch sound during music play.

        • Sky Rider

          Indeed, but it occurred to me that the same sound glitch / issue happens with every single sound. Including games, music, mp3, movies, etc. Not just music play.

          • is it ? 🙁 this sound glitch issue must be really annoying for users if exist on every sound. 🙁
            i don’t have the device and searching the net also gives me nothing, i even don’t know where to begin fixing.
            i even porting the rom as a based to one of my device, but the sound glitch doesn’t come out on mine. right now all i can say is … sorry, i don’t have solution my friend.

  • Andreas

    Hello,
    thanks for this Rom, good work.
    Flash and work prety good on my e2 duo.
    But can you please include in one of the next release a Kernel mod with cifs.ko Support?
    And in the Settings is no posibility to deactivate the Display standby (lowest time 15sec).
    Thanks

    • Hi Andreas, you’re welcome and thanks.
      About the cifs module support for samba, i’m really sorry, i don’t have the kernel source for this acer, so i cannot help you, and that’s why i’m using acer’s stock kernel on that custom rom.
      About the display standby time, even this is possible, but i never seen this disabling standby time option on any rom, isn’t that consume a lot of power from battery, no ? That 15sec to 30min delay is standard on many rom, even from google.
      However, if you’re really need to disabling this display sleep during charging, you may easily achive this by going to Developer Options on Settings and activate Stay awake.

    • thanks Rudolf.

      if you like, you may also try this xperia’s rom for this device on this article : http://www.jfdesignnet.com/?p=3517
      i know this is not like the stock rom, it’s different, but one thing i can assure you, there are no sound glitch or stuttering whatsoever.
