Recently I bought a Symphony W5 mobile – Android 2.3. This is a cheap mobile (Tk. 6,700/=) with good feature. Other one – model W10 with a slightly higher price is little bigger in size than W5, but slower than W5. So, got myself the W5. But one thing is missing from W5 (probably from the W10 too) – the notification light for missed call or unread SMS (led on mobile blinks at a few seconds interval).
Edit: A solution/alternative to this can be a 3rd party app, like “Missed Call Reminder v1” – there is an upgraded version of this app too – but not required for Symphony W5. The upgraded version blinks backlight of the touch key, which doesn’t work on this device. This can be installed directly from google play store:
Or download the apk file:
Edit [1.1.2013]: Here is an app that would blink the button back-led on missed call/sms:
I am giving the details bellow which may be helpful if any of you are interested to root your Symphony W5. Since you are reading this, I understand that you are involved in tweaking default things – be it mobile or other platform. You may know that Symphony W5 is based on Mediatek’s MT6575 chip. Do not use just any ROM (for other mobile), flashing software or scatter file you find on the web for MT6575, unless you definitely know it works. This may brick your phone. At least, I bricked my one – soft bricked. Later got it fixed by the service center. It was my fault, not to make a backup before flashing (it is possible to hard brick – mobile will not be detected by USB at all). Some of you may not understand about what I am talking about. Read on, and probably you will know. Finally, I take no responsibility.
You have to arrange a “micro USB OTG cable” and “USB male to male cable/connector”. This is the hardest part for you I think. Probably you will not find the OTG cable easily. You may search at the shops who sell Samsung Galaxy Tab – Android 4. Ask them if they have cable to connect keyboard or pendrive, to their Galaxy Tab. Other option is to make one by yourself, which I did. I shall not describe the procedure of making it, since there are lot of good tutorials on the web, youtube. Google for “DIY microusb OTG cable” or “How to make microusb OTG cable” etc. Thing is, you have to short/connect/solder ‘pin 4’, with ‘pin 5’ at the microusb/smaller side of the cable.
A tip for you, do not use the cable that came with your Symphony set or any other cheap cable or one from the dead charger. Probably you will not be able to cut these properly to get the pins to solder. You may also not get 5 pins, you will see 4 pins only. Use/buy a good cable and modify that. I have destroyed few cables. I could not reach the pins by cutting. It was hard like cement & pressing it deeper destroyed the other attached cables/pins. But with a better cable, it was done easily. And finally when it is time for soldering, use flux to make it easier and perfect. If you don’t have soldering arrangement, take it to a repair shop and show them where to solder. After soldering, It is good to check with a multimeter that other pins are not shorted by solder bridge (this may damage your phone).
Make Windows Clean & Manageable:
Hope, you have managed the OTG cable. Keep your mobile 100% charged. Now we have to flash the unlocked ROM in the mobile. I have done this on windows 7, and will describe the procedure according to that way. If you have tried to root this W5 or other android before, and installed various USB drivers, please remove them all. Start this on a fresh windows. Before installing the required drivers, create a restore point. To create a restore point, click Start, type “restore” in the search box. Windows will show several options, click on “Create a restore point”.

Next, click on Create button, enter a description like ‘symphony’ and click Create. This will create a restore point with no usb driver for your mobile, a fresh system.
When you need to restore/go-back your system to this ‘restore point’, click on “Restore system files and settings from a restore point” (See Image – 1). To get your restore point ‘symphony’ you may have to check “Choose a different restore point”. See Image – 3 bellow:
Image – 3
The above process will be needed when/if we need to change mobile phone’s IMEI. However, it’s good to have a clean restore point. If anything goes wrong, we can get it back.
Install Driver & Tools:
* Go to http://sdrv.ms/Ra2RW7
* Download and extract “MT6575 USB VCOM drivers.7z” on your computer.
* Turn off your mobile. Remove battery, wait 3/5 seconds, and insert the battery again (battery should be fully charged).
* Insert USB OTG cable to the mobile and plug the other end to your computer.
* Click on Start –> Control Panel –> Device Manager. You should see an Unknown device as bellow (Image – 4):
Image – 4
* Now, if you remove/unplug the USB cable from the computer, it should disappear. Plug again and it should appear. If not, there is problem, probably with your OTG cable. If you connect it with normal USB cable, the “Unknown device” will appear, and within a second or two it will disappear, and will reappear – endless loop.
* Hope, the OTG cable and everything is ok – when you plug it “Unknown device” appears and stays. Right click on it, click on “Update Driver Software…”, click “Browse my computer for driver software”. Click on browse, go to the folder where you have extracted “MT6575 USB VCOM drivers” and select “Win7” folder, click OK. It may ask your confirmation for installing the drivers, click “Install this driver software anyway”.
After a successful installation you should see something like bellow (Image – 5), although COM port might be different, it’s ok:
Image – 5
Driver installation is complete. Get the tools and rom file to flash now.
* Download and extract “SP_Flash_Tool_v3.1224.01.7z” from the site mentioned above.
* Download and extract “ROM-Boot.7z” from the site mentioned above.
* Connect the mobile with OTG cable as before (power off + remove battery + wait few seconds + insert battery). Check Device Manager –> Ports to make sure it is detected as “MTK USB Port” or something like that.
* From the SP Flash Tool folder, run “Flash_tool.exe”. First we will try to Read from the mobile, if it is successful, we will write.
* On the SP Flash Tool click on “Scatter-loading” button or “File –> Open Scatter-loading File…”. Browse to folder where you extracted “ROM-Boot.7z”, go to folder “Test-Read-Back”, and open “MT6575_Android_scatter.txt”. For “Download Agent” make sure it is “MTK_AllInOne_DA.bin”. Check only the “BOOTIMG”. See Image – 6 bellow:
Image – 6
* Click on “Read Back” tab. Click “Add”. Double click “PageSpare”. See Image – 7:
Image – 7
* Type a filename like boot.img and click save.
* A configure window will come. For Type check “Hex”. For Read Method – “Read Page Only”. Enter Start Address as 0x5C0000. Enter Length as 0xA00000. Click OK, and then click “Read Back”. See Image – 8:
Image – 8
* If the operation is successful, you will get a message that it was OK. Image – 9:
Image – 9
* The boot.img you get, is the original image. Keep it, in case you need in future. However, I am also including the original boot.img with the archive. In case you need to get back, use it.
* Now we will write unprotected ROM.
[ If you can’t read from your mobile, please recheck the steps mentioned earlier. Try again. It should work. ]
* Unplug the USB OTG cable and repeat the steps as before if necessary – power off + remove battery + wait few seconds + insert battery. And plug it to the computer. Check Device Manager to make sure it is detected as before.
* Run “Flash_tool.exe” if it is not running already. Click on “Scatter-loading” button and go to extracted “ROM-Boot.7z” folder, go to “Symphony-Unprotected-Bootimage” folder and select/open “MT6575_Android_scatter.txt”.
* IMPORTANT: Uncheck the PRELOADER. Check only BOOTIMG. Double click BOOTIMG to select “boot-un-pt.img” if it is already not selected. See the image – 10 bellow:
Image – 10
* Make sure that you have unchecked PRELOADER. But the file “preloader_gionee75cu_nand_gb2.bin” should be in the folder. Without this file it would not go to download mode. Just uncheck it on SP Flash Tool.
* Click on “Download” or press F9 key. It will start writing. If the write operation is successful, you will get an “OK” message as before. If you happen to get up to this, then the hard part is over. Unplug USB, remove and reinsert battery, finally turn on your phone.
* On your Symphony, go to Settings –> Application –> Applications. Check “Unknown sources”.
* On your Symphony, go to Settings –> Application –> Applications –>Development. Check “USB debugging”, check “Allow mock locations”.
* Download & extract “SuperOneClickv2.3.1-ShortFuse” from site mentioned above.
* Connect your mobile to computer with the normal USB cable (the one which came with it for charging, not OTG). Ignore, if windows shows any device driver not found error.
* Run “SuperOneClick.exe” from the extracted folder. Click “Root” button (Image – 11). This will install necessary driver, and ask you for confirmation. Click “Yes”. It will ask you for confirmation about several other options, for a few times more. Always click yes or ok. Your phone would be rooted.

* This is the end of rooting Symphony W5.
Using Clockworkmod Recovery:
With the Clockworkmod Recovery, you will be able to backup & restore ROM on SD Card. The procedure is similar as above – using SP Flash Tool. Earlier you made a “write” for boot.img and this time you would write recovery.img.
* Download & extract “ROM-RECOVERY.7z” from the site above.
* Prepare your phone – power off + remove battery + wait few seconds + insert battery, and connect with OTG cable to the computer.
* From the SP Flash Tool folder, run “Flash_tool.exe”. Click on “Scatter-loading” button and go to folder ROM-RECOVERY\Modified-ROM-CWMR\. Open “MT6575_Android_scatter.txt”
* Uncheck PRELOADER. Check RECOVERY. If it is not already pointing to “recovery_un_pt.img”, select it by double clicking RECOVERY.
* Click Download button. Image – 12:
Image – 12
* Hope you get the OK message. And CWMR is installed.
* Remove USB cable and battery from the mobile, reinsert battery. On the mobile, press and hold down Volume Up button and press Power button (while vol up is pressed – which means you have to press both the button at the same time). You should see CWMR window. You can move up or down by the Vol up/down key. You can do this with your Home and Menu button too. To enter an option, use Find button. To get back to previous menu, use Back button on your mobile. There should be a SD Card to make a backup.
* Original recovery image is also included in the archive.
* End of using CWMR.
Changing/Restoring IMEI using SN Write Tool/Station
For some reason you may have lost/erased your phone’s IMEI. There are several ways to restore it. You will get your original IMEI printed on a sticker. Remove battery to get it. To know about how to backup and restore IMEI, visit this link:
I shall describe the procedure of writing IMEI by using SN Writer Version 2.1212.0. This is for Mediatek’s MT6575 chip, which I have tested (Symphony W5 is based on MT6575). Can’t say whether it would work or not for other models. Anyway, try this method at the last time, if the methods from above link fail.
[ I don’t feel it’s a reliable software and no documentation too. There is a Chinese document though. But I can’t read Chinese. However, it works. ]
Ok, lets start…
* Download & extract “IMEI Change For Mtk6575.7z” from the site mentioned above.
* Remove all USB drivers you have installed before for your android. This time, it is good to get back to the restore point, (if) you created earlier.
* Prepare your phone – power off + remove battery + wait few seconds + insert battery, and connect with OTG cable to the computer.
* On the Device Manager, right click on “Unknown device”, click “Update Driver Software”, click “Browse my computer for driver software”, and point to folder “IMEI Change For Mtk6575 Setup\IMEI Change For Mtk6575\Special Driver\IMEI\CDC Serial”. Click on “Install this driver software anyway” if asked by windows.
* After installation remove the OTG cable from the PC and mobile.
* Connect normal USB cable which is used for charging the mobile set (not OTG). Do not connect it to PC. Just make it ready by connecting to the mobile. We would need it after a while.
* Install SN Write Station Tool. Double click SN_STATION.msi or setup.exe, found inside the extracted folder.
* Write your two IMEI on notepad.exe and keep the notepad running. We would copy these numbers and paste on SN_Station.
* An icon will be created on your desktop as SN_STATION, if not you have to find “C:\Program Files\MTK_SN_Write_tool\SN_STATION.exe”. Run it. On the “Connection Setting” -> “COM PORT” select USB VCOM. See Image – 13 bellow and arrange everything like it:
Image – 13
* Click on “Modem Database” button and select file – “BPLGUInfoCustomAppSrcP_MT6575_S01_MAUI_11AMD_W11_50_SP_V13_P4”, click on “AP Database” and select file – “APDB_MT6575_S01_ALPS.GB2.MP_”. Both files can be found inside the extracted folder.
* Click on the menu “BT & IMEI” -> “IMEI SVN & PAD”. Check Enable SVN PAD, uncheck Auto Cal CheckSum. For IMEI SVN enter value 10, for IMEI PAD enter value 2. Click OK. See Image – 14:
Image – 14
* Restart SN Write Station Tool. Make sure the settings made by you is still there.
* Click on the Start button and enter your two IMEI (copy/paste from the notepad you started). After entering IMEI, click OK. Now attach the USB cable to PC, which you prepared earlier. Do all these as quickly as you can.
* This would write the IMEI. On successful write, Write Result Indicator will turn green and another IMEI input window will come for entering IMEI if you have more mobiles. Click cancel.
If it was unsuccessful. Try the steps bellow:
1. Try again. At the first time, windows might have made some delay by initializing drivers. Test again by repeating the steps.
2. Remove USB from PC, remove battery from mobile and place after few seconds. Restart SN Write Station Tool, and repeat the process.
3. Remove USB from PC, remove battery from mobile. Restart SN Write Station Tool, and repeat the process. This time you are connecting it without battery.
4. Remove USB from PC, remove battery from mobile. Restart SN Write Station Tool, and repeat the process. Place battery quickly just after connecting the USB to PC.
Hope you will be successful.
That’s all for now. I am grateful to xda forum and many other sites, for lots of valuable information and the tools. Thank you the authors of the tools and writers of the tutorials. Thank you too – ‘The Reader’ .
Best of luck.
