Zopo 9520 (小黑2) maybe also ZP998, flashing roms and rooting

This is a guide for the Chinese version of the Zopo zp998 which has model number 9520. It seems the roms for ZP998 and 9520 may be compatible, but the bootloader is NOT compatible.
UPDATE: Roms for ZP998 can also be flashed on the 9520, but make sure you don't flash the bootloader. If you flash the bootloader you will brick your phone!
My current experience is that flashing YunOS as base firmware and flashing a customized android stock rom using CWM recovery is working best for me.
Flashing with SP flash tools (See detailed tutorial here:
1. Install the Mediatek USB vcom drivers, which can be found here:
2. Download the firmware which is normally in an archive (.zip) file, extract the archive.
Inside this archive there should be a scatter file and the system.img, boot.img etc.
3. Download and open the SP Flash tool, which can be found here.
4. Select the scatter file of the extracted archive
5. Click on download
6. Turn off your phone, and connect your phone to the PC with your USB cable (Sometimes you maybe need to hold Volume UP while connecting).
7. Wait for the popup which shows Download OK.
List of firmware I've found that can be flashed using SP Flash tool:
YunOS - 3.2.1 (Official) (Mirror coming soon)
Stock android 4.2.2 (Seems a port of ZP998)
Install CWM recovery (Not tested):
Flash the following archive using SP Flash tool: flash_recovery.zip
Booting into recovery:
1. Turn of your phone
2. Connect your phone to the USB cable of your PC
3. It should show a battery icon that it's charging only
4. Press Volume up + power button at the same time for about 5 - 10 sec. (Note sequence is important )
Rooting with recovery:
1. Download SuperSU.zip and put it on your SD card
2. Boot into recovery
2. Apply zip from SD card, select SuperSU.zip
It's also possible to root by using the SP Flash tool.
I'm using this rom:
Custom Android 4.2.2 with lots of optimizations and Gapps included: http://bbs.ydss.cn/thread-388092-1-1.html
Download link: 9520_4.2.2_optimized.zip
Installation instructions:
1. Flash Yunos 2.3.1 firmware using SP Flash tool
2. Install recovery
3. Place 9520_4.2.2_optimized.zip on your sd card
4. Boot into recovery
5. Apply zip from SD card

Do you tried yet YunOS on Zopo 998? using Flashtool and unchecking preloader?

I didn't try as I own a 9520 instead of a 998, but that should work I guess. As people with the 9520 can also install roms of 998.
@Naffeshamed: You can just flash roms of zopo zp 998 so if you can either buy it in China or buy the Zopo Zp998 from aliexpress.com its nearly the same price actually.

But i always need to uncheck preloader, right? I'm asking around and let you know asap
i saw that your model has more support from chinese devs ! That's why i would like know if i can flash their rom aswell , give you some info asap
If you can mirror the YunOS file would be great , bbs so slow... Mega would be great

Dear Friends
I have messed up my phone, i recently downgraded from android 4.4 to 4.1.2, and now my phone is messed up.
I dont have original stock ROM backup.
Now the problems I am facing
1 - When I am flashing stock ROM with odin the phone is working fine but NO CALL, NO BLUE TOOTH - phone is showing NOT CONNECTED TO NETWORK
2 - When phone is kept idle for few minutes then screen does not turn on with home button - I have to restart the phone.
If anyone know how to solve this problem then kindly help.

Download new stock rom
This had happen to me , don't worry just download the new stock rom from SamMobile or from torrent. But remember to download and flash stock rom as per your device country details.
http://www.sammobile.com/firmwares/database/GT-N7100/
Or download from torrent( just search your desired PDA and search its torrent )
Alternatively download any new rom, cynogen 11 or any favourable.

Also can I update with KIES...any advice

If your device is not rooted you can update via kies but if it is rooted you have to flash the rom by your own. And to know about your device specific PDA. check the firmware under setting>> about device and then search for the PDA in sammobile site , also enter your country while filtering , you will get the list of all available stock Rom there.

thanks a lot

Step1- Download Stock ROM from SAMMOBILE (for your device)
Step2- since you are in DN4... you would be having custom ROM -- clean your device by formating system/data/cache/etc etc
Step3- go to download mode (volume down+menu+power) and connect to your PC where ODIN is running...ensure you have Samsung USB driver installed on your PC
Step4- flash stock ROM downloaded in step 1
that is it....
Cheers

No It wont.... System, Data, Internal storage are the ones you should clean up when ever you change your ROM...
Samsung stopped at 4.4.2 for Note 2
DN4.2 is TOUCHWIZ at 4.4.4 (SG3 base ROM)
CM12.1 is AOSP, 5.1.1 r8

Lenovo A7000 STOCK MARSHMALLOW [Android 6.0] FLASHING WITHOUT SP FLASH TOOL

I recommend using the SP FLASH TOOL method for flashing stock ROM if possible.
TO FLASH THIS STOCK FIRMWARE via SP Flash TOOL Click here
THIS is Lenovo A7000 Stock "MARSHMALLOW [Android 6.0]" OTA UPDATE.
version : A7000-a_S223_160405_ROW_WC814D6764
This method is the alternative method to the SP Flash tool.
I have tested it and it works:-
First, when I am on stock Lenovo rooted lollipop ROM(ver.S153_151127_ROW).
Secondly, it also worked when I am on marshmallow rooted ROM (ver.S223_160405_ROW).
The third time it works when I am on vibe 3.5 custom ROM [MM based] with custom kernel.
If you have a rooted device, your device will unroot after installing the update.
If your device is not rooted then also it works like a charm.
To install or flash this OTA ROM
1. You should have Lenovo stock recovery installed. Use any one between method a or b
(a)If you want you can Flash stock recovery via TWRP. Click here
(Procedure is the same as installing zip file in TWRP).
(b)Flashing stock recovery via SP flash tool. Click here
(Run spflash tool Download and unzip the package, load the scatter file and flash it in "download only" mode)
After flashing recovery immediately boot into a recovery check if the recovery is installed or not if not then flash recovery again.
2. Download the stock ROM from the Lenovo server.
DOWNLOAD LINK: click here
3. Now make the two copies of the downloaded package first one in internal storage(not in any folder).
4. Rename the package to update.zip to the one in internal storage.
5. Then Boot into recovery (Power + half a second the two volume buttons), then select English as recovery language.
6. Now select install update package. It will give some warning click yes then the update will start.
In between, you will feel that update is stuck don't worry it is updating, after update your phone will reboot automatically. (update may take 10-15 minutes)
WHATEVER YOU DO AT THIS AT YOUR OWN RISK. NEITHER I NOR XDA WILL BE RESPONSIBLE IN CASE OF ANY HARDWARE/ SOFWARE DAMAGES CAUSED BY YOU TRYING THESE METHODS. YOU WILL BE SOLELY RESPONSIBLE.
IF THIS THREAD REALLY HELPS YOU THEN PLEASE TAP THANKS.

If you want to flash through SP Flash tool the go to this thread:-http://forum.xda-developers.com/android/development/lenovo-a7000-as223160405-row-andoid-6-0-t3360467/post66404777#post66404777

Shows you which error?
Did you try to install it via local update?
Anyway, your best bet is to install TWRP and flash the CN ROM through TWRP.
Alternatively, use miflash tool in the unofficial unbrick tool to flash the CN firmware via edl mode

Nubia package error
Bro when I purchased the phone the software was 3.16 global,then I changed it to 4.16 with local update,but I was trying the same thing with the Chinese software when I go to the local update and I press the install button the mobile shut down and goes to the software installation but after 10% or something it shows package error and just reboot it self.i don't know what to do now. sorry my English is not good

Use TWRP; follow the link below, root your device then flash CN ROM from TWRP.
Back up your data cos flashing TWRP will wipe everything.
Also, when installing CN, get version 6.23
All the best

There you are. Its the 6.23 version of the cn rom
This directs to the 5s version but both the 5s and 5g versions of this rom are identical. ( Md5 checksum proves its the same file)
Flash from recovery. Or through TWRP

Otg refers to a external usb device you connect to the phone. If you have the update.zip on the root of the internal memory it should show up.
If it does not. You should use the root without unlocking bootloader tutorial to install TWRP. The zip will flash from there with no problems.
