THL5000 Ultimate ROM by Dimid/iv2012 - in my opinion this is currently one of the two best ROM the best multilanguage ROM for THL 5000 (second is Classic V3mod ROM).

I am not the author of this ROM, made only a few adjustments and necessary small translations from russian (some texts were only in russian) to other languages. This is the last ROM from really excellent  ukrainian author Dimid/iv2012 (see below to his page and donate him on WebMoney). Dimid collected all the best form all his previous ROMs. Power consumption is good, ROM is multilanguage as Classic V3mod. This ROM is continuing of Classic ROM V3mod. He used part of the code from: Philips i928 1436_00_V17A_CIS, THL 5000 v1.1.2, DEXP Ixion XL 5 v1.8H. Thank Dimid for all of his hard work. This ROM I posted here with his permission. Kernel patch for old displays was made by jitnovod from russian forum. I uploaded it here, to make ROM available for non russian speakers, which can't log on to the Russian forum.  I prepared modified version,  where removed the residual cyrillic and added missing translates.

To see all supported languages click here (picture): http://www.needrom.com/wp-content/uploads/userfiles/2015/all3.jpg

Installation:
Before flashing  make a full backup of the current system in TWRP (Boot, Logo, Nvram,Recovery,Uboot,System,Data). If you will want to return previous ROM, simply restore the backup.

1) install drivers on PC (support Win 7/8 – 32/64bit)
- unpack archive "Driver_Auto_Installer_v1.1236.00.zip" to folder e.g."C:\x\", will get folder "Driver_Auto_Installer_v1.1236.00"
- in this folder run as administrator file "Driver_Auto_Installer_v1.1236.00\Install.bat"

- now press Enter, the window will close
- restart PC

2) Install ROM – Flashtool
- upack archive "THL5000_VibeUI_1.5GB.rar" to folder "C:\xx"
- unpack file "SP_Flash_Tool_v5.1352.01.rar"  to folder e.g. "C:\xxx" and run file "flash_tool.exe" (when you first start the following error message appears, click OK)

- then will open the program window, on the right side, click on the "Scatter-loading" and select the file "C:\xx"\MT6592_Android_scatter.txt and click on "Open"

- will get this screen

- in the menu Options\Option\Download set checkbox "DA DL All with Checksum"

- go to TWRP and install combo patch file NewTranslat&Patch_6.zip (click Install button, then button Wipe Cache/Dalvik, then click Restart button) – it will install all Dimid patches and additional languages.

Adittional patches
- The core for the new display type - VibeUI_boot_1.1.2_fixed.zip 
- All other original patches  BT_Fix.zip, ideaFriend.zip, GreenLed100.zip, ScreenRecorder.zip are now included in one combo patch file NewTranslat&Patch_6.zip.

Why is this version FlashTool, not for TWRP? Because Dimid had  to repartition the memory to increase the size of the partition / system. In our small stock section does not fit the big firmware. If in the future you will be flashed using Flash Tool other firmware, it is necessary to save the layout to be copied from the replacement of the firmware files MBR, EBR1, EBR2, MT6592_Android_scatter.txt. Marking does not affect the subsequent firmware through recovery. His older backups also can restore this layout. Now under the system allocated 1.5 GB of internal card about 9GB. It was in the drain 800 mb, 9.77 GB. Size Userdata stayed prezhdnemu. All future firmware will do in view of the new layout. (Translated from russian).

THL 5000 SGS_UI – newest ROM from excellent  ukrainian author Dimid/iv2012 (see below this post  and please donate him on WebMoney, it's a pity that Dimid  hasn't Paypal), based on slightly improved Ultimate ROM engine, GAPPS are included. Some people asked me to upload ROM here, Dimid gave me permission.  I prepared special patch which remove the residual cyrillic and add missing translates.

Languages:  Multilanguage

Mistakes: Samsung Contacts application has a small bug, does not search contacts by clicking on the alphabet at the right edge of display (see additional patches). It's a trifle, normal search window works well. If you want to use  contacts search by clicking on the alphabet at the right edge of display, install exDialer from Google Play.

Installation: (as usually from TWRP)
1 - save the ROM file on the SD card
2 - jump to TWRP recovery, if you haven't it, install it (installation instructions are here, sorry in slovak language only,use Google translator): http://androidforum.cz/twrp-2-7-1-0-root-pre-thl-5000-t57731.html 
3 - click Wipe and select items: Dalvik Cache, System, Cache, Data, Int.SDcard (optional) and Android Secure, then click Swipe to Wipe
4 - click on Install, choose ROM file and install it - click Swipe to Install, then click Reboot System
5- go to TWRP, istall file SGS_UI_NewTranslates2.zip - click Install, then Wipe Cache/Dalvik, then Restart to system
5 – finish 

Otional patches ():
SGS_UI_NewTranslates2.zip - remove residual russian curillic and add new translates
Root_thl5000.zip - install Superuser.apk (ROOT) - necessary for e.g. TitaniumBackup, etc.
Kernel110_old_disp.zip - Kernel for old type displays (repair Gama value to "2.0")
Modem_st_850.zip – for testing purposes, original THL modem 850/2100MHz. If you have problems with wifi/3G, try this. It will replace integrated 900/2100Mhz modem from Dimid (several people reported small problems, me not). This modem may be used in any Dimids ROM. If you do not have problems, do not install.


Other patchs are not necessary now. Everything is integrated in the file UltimateV3_NewTransl&Patch1.zip.

Two alternative patches, which are mutually rewritten, therefore always install only one of them:
Dialer_ST1.zip – Install classic Dialer and Contacts from firmware Ultimate ROM (fully support flip cover)
Contacts1.zip – Revert back Samsung Dialer and Contacts. This original Contacts have a small error, does not search contacts by clicking on the alphabet at the right edge of display. Caution: if you are using sync Google contacts, patch erase them! After installation, it must therefore be re-synchronized.

I've ported CM12.1 for our beloved THL 5000. There are some small bugs that should be easy to fix except the video recording (which maybe will be fixed by fire855, who originally brought CM12.1 to MTK6592 devices and whose port is my source). As I depend on my phone nearly every day and can't afford another one, I won't continue porting / fixing. But I'm pretty sure the small bugs can be fixed by the community.

Issues

• Video recording (en/decoding) [use 3rd party app; will be fixed soon be fire855]
• apk installation is very slow
• laggy scrolling
• simcard settings get lost after reboot [unconfirmed]
• no battery usage statistics [unconfirmed]

Installation

1. Download the ROM
2. Download GApps package
3. Put the zip files on your SDCard
4. Reboot in Recovery
5. Wipe Data/Factory Reset
6. Install CM12 zip file
7. Install GApps zip file
8. Reboot system
9. Enjoy CyanogenMod 12

THL 5000 Lite ROM 2.1 - all Lite ROMs are very fast and smooth, there is no lagg of any kind, works perfect, fast and smooth. Based on stock kernel 1.1.2. In my opinion, this is currently the best ROM.

This is the third version of the Lite ROM (1.0, 2.0, 2.1) from excellent  ukrainian author Dimid/iv2012 (see below this post and please donate him on  WebMoney, if you have  an account there). It's a pity that Dimid  hasn't Paypal. ROM advantages are: pure Android, small size, simplicity, speed and low battery consumption. ROM is ROOTed, GAPPS are included, OTG works. Dimid gave me permission to upload ROM here.  I prepared  a little bit modified version where removes residual cyrillic, added missing translates and made a few small changes (see changes). I'm excited from this ROM  - I have installed Gravity Box through which I set what I need.

Languages:  Multilanguage

Installation: (as usually from TWRP)
1 – save the ROM file Lite_v2.1_Odex_2.zip on the SD card
2 – jump to TWRP recovery, if you haven't it, install it (installation instructions are here, sorry in slovak language only,use Google translator): http://androidforum.cz/twrp-2-7-1-0-root-pre-thl-5000-t57731.html
3 – click Wipe and select items: Dalvik Cache, System, Cache, Data, Int.SDcard (optional) and Android Secure, then click Swipe to Wipe
4 – click on Install, choose ROM file Lite_v2.1_Odex_2.zip and install it – click Swipe to Install, then click Reboot System
5 – enable notification LED in Settings/Display/Led switch -> Enable what you want
6 – enable Adblock in Settings/Additional Settings/Adblock -> Enable  (Download and apply blocking)
7 – finish
8 - If you will install Gravity Box, do not forget change default setting in Phone tweaks/Telephony/Fullscreen caller photo, set it to Partial and restart phone (otherwise no hangup button on incoming calls)
9 - Do not change the default value in the Settings/Developer options/Animator duration scale, always must be set min. to 0.5x (otherwise Dialer won't work correctly)

Do not play with Lock button in Settings/Additional Settings/Download EPO.dat! For normal operation it required an internet connection at the time of GPS launch! I do not use EPO function and GPS fix works quickly and well. I recommend do not use this option. If someone wanted to use this feature, here are instructions in russian language (use Google translator) - http://4pda.ru/forum/index.php?s=&showtopic=592576&view=findpost&p=42175265

Optional patches (Important: Install it in TWRP: click on Install, then click Wipe Cache/Dalvik, finally click Reset to system):
- Kernel110_old_disp_fixed.zip - core for old display type (install when your Gama is different from value 2.0)
- Unlock_VolKey.rar - unpack RAR archive, will get two ZIP files, first enable display unlocking by the volume buttons, second revert it back (if you use Gravity Box, works key Volume- only)
- Unlock_Profiles_Lite2.1_1.zip - add a new option "More Ringtones" for selection of ringtones from MP3 albums on your SD card (Settings/Audio profiles/profile name/Ringtone/Sim/1st option "More Ringtones"
- Modems.rar -  unpack RAR archive, will get two ZIP files, first install 900Mhz 3G modem, second install standard 850Mhz 3G modem (I think the 850 MHz modem works better, but someone want to me 900Mhz, so added)
- SMS_icon.zip - change the icon of the SMS application to standard

1. give e.g. MP3 file to folder "Notifications" on SD card.
2. Then set it in Settings/Audio profiles/General/Notifications
