This is stock, clean, unrooted Zopo ZP998 KitKat ROM published by Komu, version 1.03

Taking into account new models coming from Zopo, i believe this ROM may be the final stock one (just thoughts.)

Чистая заводская прошивка KitKat для Zopo ZP998 от Komu, без рут-доступа, версия 1.03

As opposed to Zopo, Komu ROMs usually do not contain any malware (Caivs or lovelyfonts e.t.c.).

Flashing (and optional rooting) instructions: (all your data will be lost, make backups preliminary!)


1) Download and extract the whole package "K83G-103.zip" to a safe place with minimal path length, say, "d:\ROM"

2) If not done yet, install drivers from "1 – DRIVERS" subfolder

3) Shut down ZP998, remove SIM-card(s) and microSD memory card from ZP998

4) Remove all your files from your microSD card (backup to PC), make it clean (otherwise be prepared to problems after ROM install)

If you have a new clean microSD XC, it may be factory formatted as ExFAT, that is unsupported by ZP998. Reformat it to primary partition with FAT32 with Minitool Partition Wizard http://www.partitionwizard.com/free-partition-manager.html (Other file system options for memory card will not be discussed here)

5) Remove battery from ZP998

6) If you do not want to root your phone, please skip the next step and proceed to step 11) right away)

>root> 7) Download a modded recovery, this will do: https://www.needrom.com/download/zp998/

>root> 8) extract the recovery.img file only from the recovery zip, and place it into "3 – Firmware" folder, overwriting the stock one

>root> 9) Download the SuperSU zip (see links above)

>root> 10) Do not extract the UPDATE-SuperSU-v2.40.zip archive, just copy it to the root of your microSD card as it is

11) Optionally, if you want to repartition your internal memory to have more room for applications (10GB), you can download (see links) the EBR_10GB.rar archive, and extract it's contents, two EBR1 and EBR2 files to "3 – Firmware" folder, overwriting the old files.

12) Connect your proven quality USB cable to PC only, leave other end not connected to ZP998!

13) If it is not friday on your calendar, navigate to "2-  Flashtool 5.144" folder and start flash_tool.exe

14) It is possible that you get and error saying about scatter not found, just proceed with OK

15) Now, you must manually point the Flash Tool to the correct scatter file. Click "Scatter-loading" button, and go to "3 – Firmware" folder to find the "MT6592_Android_scatter file" (ckick it to choose)

All other fields will be filled automatically.

16) Now, it is very important: the next option depends on what Android version you currently have on your ZP998 (i.e. the ROM that you are going to "overwrite")

- If you have another veriety of KitKat, you must use "Download Only" dropdown option in Flash Tool

- If you have a 4.2.2 (JellyBean) ROM, then you must use "Firmware Upgrade" only! Otherwise you can lose IMEI and get into trouble!

The general rule is:                                                                                                                    

- installing same Android version —> use "Download Only"                                                      

- installing different Android (from 4.2.2 to 4.4.2 or from 4.4.2 to 4.2.2) —> "Firmware Upgrade"

Never, NEVER use the "Format All + Download" option! You WILL lose your NVRAM and IMEI data, and will have a very bad time trying to recover them. Never try this option, even if you get stuck flashing. Point. This option is for experienced ppl only who know what they want. You have been warned.

If you have a Zopo 9520 phone, not an original ZP998 one, then i warn you to not flash the preloader part of firmware (uncheck it in Flash Tool). I have never had a 9520, and can not assist with how to tell it from ZP998, maybe by a sticker under battery. In other words, if you have a 9520, be twice alert doing anything, and stop immediately if unsure! Problem is "Firmware Upgrade" mode demands all parts of ROM to be checked to run. To overcome this, you may try borrowing preloader from another 9520 "KitKat" ROM, but i do not recommend doing it and i will not be responsible if you fail. 

17) In Flash Tool, click the "Download" button with the green arrow. Your PC will be waiting for connection now.

18) Without the battery, grab your ZP998 in your left hand (screen facing you), so that you can press and hold the "volume up" button with your thumb (do it).

19) Connect the spare end of USB cable to your ZP998 USB port and with your free forefinger, press the phone "power" button (still holding the "volume up")

20) There should be some activity started with your PC (Windows reporting of a device detected/connected, e.t.c.) and promptly, there should be a progress bar in the lower part of Flash Tool moving.

21) If everything goes well, the progress bar changes colors at different stages, and after few minutes, you will see a square popup window with a green checkmark.

If you get a "PMT has changed for ROM…" error in Flash Tool, do not panic!                              

You have to rollback to a stock JellyBean ROM first, let it be, "14-06-18",                                        

http://www.zopomobileshop.com/content/9-download-zopo-mobile-latest-rom, look for this download:

ZP998 4.2 140618 451MB 18/06/14

download it, do anything as described here from 1) (skip recovery and root parts), and then start this manual once again from the beginning, with all options and cautions, to upgrade to this KitKat. 

If you have encountered any other error , better stop and ask someone experienced for help

Now, presuming you have just flashed successfully the new KitKat 1.03, do the following:

22) Unplug USB cable (you can exit Flash Tool application), and insert the memory card into your ZP998. Do not insert SIM card(s) yet – you can do it any time later. Insert the battery.

23) If you chose earlier not to have root, you can power your ZP998 on and start using it. The first boot will be a bit longer than usual. And, you are done with flashing. If you connect to Wireless during the setup wizard and log into your Google account, all your applications and settings will be automatically downloaded to the phone (in case you checked that option in the previous ROM). If you want to start from scratch, skip both Wifi and Google account parts and set up everything manually.

If you made the rooting parts previously, you need a few extra steps:

24) You need to get into modded Recovery first, to flash SuperSU update. To get into recovery, you must power on your phone, while you hold the "volume up" button, and the phone is connected to PC or charger. These conditions are mandatory! You will not get into mod.recovery if you do not press "power" and "volume up" and your phone is being connected to PC or charger. Do not be confused with "power" and "volume down" option to get to Chinese Engineering menu. This is different!

25) Once in Recovery, choose "Install", and select the "UPDATE-SuperSU-v2.40.zip" file that you recently have put on your memory card. Swipe to install it, and then reboot. Once in Android OS and complete with setting Wifi and Google account, download the fresh version of SuperSU and install it.

26) The final touch is to make sure SuperSU works as supposed. Start SuperSU app, go to Settings tab, scroll down to Security and uncheck "Mount namespace separation" (this may look different with your language, 3rd checkmark in security list in current, 2.40, version).

There you go, ready to use your new KitKat.

I highly recommend you to install Xposed framework and GravityBox [KK] to highly enhance the ROM features.

    Thank you for this "all you need" compilation. And thank you for the manual which contains answers to the most common problems. This is the starter pack I wanted to prepare for ages and never found the time. ;-)

    I am rather happy with the Komu 1.02. Is there any improvment with this new rom?

    • 03/06/2013


      No idea, too little time using 1.03. SO far, i am happy. Btw, with 1.02, i got terrible lags with both launcher and touchscreen after some time.

    Thank you for sharing ;) Do someone know if this rom corect the inverted gyroscope ?? for google cardboard and gps issues

      Are you sure about gyro with ZP999? It used to be ZP998 issue. I have checked some testing app, not sure now which one, with ZP998 and ZP999 side by side, and their behaviour was opposite to each other in gyroscope test, i.e. if ZP998 has inverted gyro, then ZP999 should have a correct one.

      I have just checked the Jurassic VR, a GoogleCardboard demo from Google Play, ZP999 is working 100% perfect, whereas ZP998 has inverted axii.

      As to GPS, ZP999 has a perfect one, and this ROM does not make it worse. I get fix in few seconds (2-5s) and accuracy is up to 2m.

      This is ZP999, not ZP998!

    • 08/14/2014


      I was about to install this ROM to correct this axact issue. Did you ever find any solutions?

  6. 08/02/2014


    yes i'm talking about zp 998 ;) this rom is for 998 not for 999 No ?!

      oops… This IS ZP998 ROM, for sure. I've been thinking about ZP999 at the time of posting, sorry.

      Gyro is still inverted, sorry.

      This ROM is for ZP998, no worries!

  7. 06/01/2014


    Thank you for this ROM. it works like a charm! Much better than previous ROMs I have used! And the manual is very well made!

  8. 07/25/2013


    I agree. Best rom I ever used in my zp998. With my use (moderate) of the phone, near two days with the batery!! And very smooth.

  9. 08/02/2014



    The Installation just looks scary, but if you have a little understand of Flash Tool, it will not be a problem.

    one of the best rom for zopo zp998.

      I made it scary, because people often skip reading, and then… then they start asking "how do i restore IMEI".

    Help after installing this ROM everything is working fine except that the battery drains much faster. I lost 35% of the battery on standby after 3 hours. Pls any solution to that.
