Dev Oma along with Astralix, JochenKauz and netlars have worked feverishly to create several revisions of the Oma Rocks ROM. Below are the revisions and patches linked to make your v88 (and v88s) purr like a finely oiled machine. Each ROM version has ClockWorkMod (CWM) and provides Root permission in its build.
The explanation for Oma's build number nomenclature is below:
v3.x - JB 4.2.2
v4.x - JB 4.2.2 SDK2.0
v5.x - JB 4.2.2 SDK2.0 multi window
Below are DL links and benefits of the latest release for each type of build (v5.x, v4.x and v3.x)
PLEASE NOTE THE FOLLOWING: CHUWI HAS CHANGED OUT HARDWARE FOR THE SCREEN CONTROLLER FOR 2ND GEN MODELS OF THE V88. 2ND GEN MODELS CAN BE IDENTIFIED BY THEIR S/N. MODELS WITHOUT "QUAD" IN THEIR S/N ARE CONSIDERED 2ND GEN MODELS (THIS CAN INCLUDE THE "TIG," V88S AND V88HD MODELS). 1st Gen models (V88 QUAD, V88S AND TIG) should use kernel Bob#160 which is the default kernel in the later builds of this ROM.
2nd Gen model users should check what kernel currently is being used in with their firmware before flashing this (Settings menu - About tablet - Kernel version). Once you have ID'd your kernel number, swap out the kernel in this ROM with your compatible one.See this post which provides DL links for all the 2nd GEN kernels. Make sure you flash your 2nd Gen model using the correct kernel or your screen will not work (you will get a black screen) and will need to reflash your tablet. See this post on how to swap out your kernel if you get a black screen.

Flashing Instructions for Installing Oma Rocks ROMs:
1. Copy format_NAND fix to sdcard
2. Hard power off your V88 (hold power button until it powers off)
3. While holding Volume+ (up) button
4. Plug USB into your PC (update mode)
5. Install missing drivers from driver folder if you have not already
6. Run RKAndroidTool.exe as Admin (click right)
7. Select EraseIDB (current should count up to 4096)
8. Select Flash Rom
9. V88 will boot into CWM
10. Run format_NAND fix (install zip from ext_sdcard)
11. Reboot
12. wait 4 minutes
NOTE: Oma has provided a new kernel (bob #160) which can be flashed with this ROM. Link to kernel download can be found here.
Patches:
NAND_fix - batch file which is installed via CWM ("install zip on sdcard" or "external sdcard" commands in CWM) allowing tablet to properly mount external/internal SD card and wipe cache
PhabletUI - batch file which is installed via CWM (("install zip on sdcard" or "external sdcard" commands in CWM) allowing tablet's UI to use the "Phablet" UI style
TabletUI - batch file which is installed via CWM (("install zip on sdcard" or "external sdcard" commands in CWM) allowing tablet's UI to use "Tablet" UI style
Patch Install Directions:
1. Copy patch file to your external card
2. If installing Oma ROM for the first time, ROM will automatically install CWM and boot into CWM once installed
2.5 If already installed Oma ROM, boot into CWM by either using recovery app (like Quick Boot) or do a hard shutdown and then hold the volume "+" and then power button for three seconds and you should boot into CWM
3. Once booted into CWM navigate to "install zip to external sdcard"; navigate to where on external sdcard patch file is located and install
4. Reboot into system using CWM
*Note: if your patch file on your external sdcard isn't seen at first, try removing and re-installing card and look for it again.
Oma Rocks ROM Revs:
Note: Early Oma Rocks ROM builds may be incompatible with your device as Chuwi released modification to hardware. Version 3.3 and up account for these changes and should work on all v88 and v88s. Lower versions may cause your tablet to "soft-brick" and should not be attempted. Discussion of v3.3 and later builds starts on post #71 and forward
Build v5.3a (JB 4.2.2 SDK2.0 multi window)
Based on Chuwi's 08/01/13 firmware release.
