Developed by Sambaaa
Hello everybody, I prepared a new custom rom compatible with ANY Iocean x7 based on latest stock firmware for Iocean Elite (02/12 version). I implemented Aroma Installer from Gamma v1.2 onwards and rom zip is now the same for any Iocean x7 (Youth, Youth Turbo, Plus, Elite).

Report there your feedbacks both positive or negative, they'll help me to improve this rom in the future!
Read carefully first two posts in GammaRom thread on xda forum before flashing in order to get the best experience using this rom:
- post #1 is related to rom's features and installation instructions
- post #2 contains a brief post-installation guide on how to configure it at best.

Installation guide

To flash this rom you need a custom recovery as CWM or TWRP. You can download TWRP for all Iocean from here. Otherwise if you prefer CWM, download this CWMrecovery.img for Iocean x7 Youth/Youth Turbo or this one for Iocean x7 Plus/Elite and flash it through MobileUncleTools app. I strongly recommend you to take a Nandroid Backup before flashing this (or any other) rom. I recommend you to backup your IMEI too. To do this you can simply write both IMEI on a piece of paper (you can find them in Settings > About Phone > Status > IMEI information)
To install it, follow these simple steps:

Great job Sambaaa! I use this rom for 2 weeks and it is working perfectly. I have one question: how can i disable the icon of the sim 1 or sim 2 (at the top on the screen)? Thank you.
Hi, you mean icon of the sim you're not using, right? Launch GravityBox > statusbar tweaks> autohide Sim
Yeah, thanks! I have 2 wifi connections: one at work and one at home. Unfortunately, I can use wifi just at home. At work i can also make the wifi connection but it don't work (password is not wrong and the other settings are OK). Before installing this rom I had't this problem. Is there a restriction in the settings to use 2 wifi connections? Thank you in advance.
No, of course no restriction to number of wifi connections. Your router at work may be incompatible with a few build.prop tweaks. Try to delete all 3G turbocharger entries in /system/build.prop, you can find them at the end of the file. Save edited build.prop and remember to check that permissions are set to rw-r–r– or you'll get into a bootloop. Reboot needed to apply changes
Sorry, how can i get acces to /system/build.prop? this settings are for me something news.
If you tell me what's your iocean model, I can send you a flashable zip to do that.
Anyways which gamma version are you running? Gamma v1.4 is slightly different from v1.3 even for what concerns connection management (v1.4 should less likely give issues than v1.3).
iOcean x7 plus. Now I running Gamma v1.4
Thanks
Flash this in recovery with no wipe above your gamma v1.4

that's for x7 plus only
Lags on games (minion rush specifically)
Does it lag more than stock rom or the same? Anyways to play games of any kinds without lags, you can try resolution changer script that I prepared for this rom. See here:

Hi Sambaaa, first of all, I would like to thank you for your non-stop developing of rom for iOcean X7. Generally your rom is much smoother than the stock rom. But when it comes to playing games especially HD games (minion rush, NBA), it is just the same with stock and other roms I tried, it lag. On minion rush, it has a delay on the movement of the character with the slide of finger. I already lowered the resolution to the lowest but it doesn't help.
Before I use the Youth 1gb 4gb. Thinking of maybe it is because of the small ram (1gb) together with MTK6589 (1,2ghz) CPU that is why it lags. Now I use it the Elite 2gb 32gb, unfortunately, just the same.
Just want to share some information. I also used the phone ThL (W300 and W11) 2gb 32gb, it also lag (on games). ZTE 697s, Jiayu G4A, Huawei G700, on these phones, it is smooth (games).
Thanks very much again Sambaaa
Yes, it depends on one thing only: screen resolution. Iocean, thl w300 and thl w11 are all provided of a FHD screen. Huawei and Jiayu have a simple HD screen and ZTE has just a QHD screen. They all share the same MT6589(T) SoC which has a pretty week GPU, at least a bit too weak for a FHD screen. Resolution changer script goal is to try to reduce lags due to GPU weakness, but lowering resolution via software is not the same as having a real HD-QHD screen: smoothness will increase, but not be the same as a real HD-QHD screen. I'm afraid there's no much I can do because it mainly depends on hardware…
Thank you Sambaaa, I flashed the wifi fix, i will try it monday at work. I made also a small donation, i know, is not much but it's just for your support.
Thank you very much! That's really much appreciated
Hope that patch really solves your issues since it removes the only difference in connection management between gamma and stock.
Hello Sambaaa,
thanks a lot for your work. I will flash this week and then donate if it works for me. I have some questions for now:
- will there be version 1.5 any time soon?
- why backlit keys work only on youth model – don’t other models have led’s ot is it a sw problem?
- does light sensor work on elite?
- how did you fix your gps antenna – same as shown on several youtube videos?
- are google play ghost touches fixed in your rom? recently i’ve been experiencing these also i google plus app
Thank you!

Hi and thank you in advance for your support
-yes, I'm working on it. Main goal of that version is to extend 52 languages support to almost all system apps. Scrolling and smoothness will slightly improve too. Anyways you can flash v1.4 because I've created and incremental upgrade feature for v1.5 which will detect your rom version, x7 model, … and customize rom upgrade modifying only necessary files, not the whole rom from scratch, so you won't lose your data in v1.4 –> v1.5 upgrade.
-only first released x7 youth have hardware keys backlight from an hardware point of view. No x7 turbo, no x7 plus and no x7 elite support that feature because they're missing leds (AFAIK), so there's no way to enable them.
-I got youth, so don't really know about elite, but I guess it's the same: they all have light sensor, but doesn't work really well (seems to set just two values: 100% and 0%).
-I (and other users) described many different hardware mods in this thread: http://www.androidiani.com/for.....ntenna-gps.html
The one I'm using is similar to this one posted by another user on htcmania forum http://postimg.org/image/6ktfk.....7qgh/
Anyways iocean created a new gps antenna that you can buy contacting them through iocean official website here http://www.iocean.cc/ContactUs......html
They'll send you a new antenna and this guide to follow http://www.mediafire.com/downl.....-25%20guida.rar
-that cannot be solved through a rom update, it depends on touch driver, follow this procedure, but be careful because it's really dangerous (and works on iocean elite only, other x7 will be bricked):

Enjoy!
thanks very much
Thanks Sambaaa for the clear explanation.
