[Lenovo P780] stympy:
Hi.

Your firmware currently installed is Chinese for sure. Its old allright! All stock firmware is old because Lenovo builders gived up on this nice phone.

So... first thing first...

You must upgrade your system first in order to install one custom firmware. I think is what you want.

To upgrade your system you must work with SP FLASH TOOL. SP Flash tool is not a program to play with if you dont know what are you doing. 99% of people who used this tool and did not know how to... corupted NVRAM and lost their IMEI.

So... lets begin.

A. Tool to be downloaded:

1. SP Flash Tool V.5 and v.3. This 2 tools are made for Lenovo P780.

2. Divers like zip file and exe file.

3. Firmware multilanguage for your phone. This firmware is CN Based but dont wory to mutch, is custom made and compiled for multilanguage and is working well. I used very long time.

4. TWRP custom recovery.

B. Drivers installation procedure.

1. First drivers instalation. This small tutorial is for installing drivers if you never installed on your device:

1.1 First install the .exe file. Reboot PC.

1.2. After reboot plug the phone (powered on) to the PC and new hardware wizard will appear. Install driver if windows will wants too.

1.3. Now power off the phone. And open the Device Manager.

1.4. Again plug the phone to the PC or laptop this time powered off.

1.5. At this time in Device Manager appeared for a second or two not in PORTS area something with.. MTK65xx...

1.6. Click very fast on it because that will dessapear very fast.

1.7. After you clicked on it all you have to do is update driver. Browse for the driver unzipped. Install.... yes yes... next next... blah blah.... Finnish. :D . And voila you have drivers installed and now all you have to do is to flash you ROM.

C. Flashing procedure:

1. now... turn off your phone

2. plug your USB cable in your computer

3. do not plug your USB cable in your phone

4. open Flash Tool and unzip the firmware. Remember the adress of your folder where you unzipped the firmware. Load scatter file from that folder.

5. check DA,DL WITH CHECKSUM (NOT OPTIONAL)for v.3 not for v.5. Version 5 is allready checked. Look at those 2 pictures attached.

6. press Firmware Upgrade button (NOT DOWNLOAD BUTTON). For version 5 select FIRMWARE UPGRADE. Look at those 2 pictures attached.

7. now... just now plug usb cable to your phone.

8. firmware flash should start.(some red and other color lines should appear)

9. iff the firmware is not starting remove the back case of your phone and hold pressed the little red button from the right side, for about 20 seconds then release. All this must be done with cable pluged in to your phone.

9. after flash is done a green circle or some ok should appear

10. disconect your phone and power on your phone

11. lenovo logo should appear. then you should be pacient because it will took some time before android boots for the first time.

12. Reboot at least once, then your phone is ready to work HARD. :D

D. Installing TWRP. This custom recovery is good for custom firmware and full system backup.

Power Off your phone.

1. After power off your phone open Flash Tool and browse for the scatter file your folder where are the recovery.img and scatter file.

2. Now comes the tricky part . Creeate a new folder on your Desktop. In that new folder copy TWRP recovery and scatter file from your firmware folder.

3. Now load the scatter file and mark DA DL with check sum in SP Flash Tool v3. In SP Flash Tool v 5 dont need. They are allready selected. Recovery.img should appear checked. If not, checkit.

4. Press Download NOT FIRMWARE UPGRADE.

5. Now, just now plug the cabble on your phone. Download should start and a green circle should appear.

6. After this you should have custom recovery TWRP installed.

7. Then boot directly to recovery your phone by pressing power with vol + and vol - butons together. Not Optional because TWRP will overitten by some files and stock recovery will appear.

8. After you entered in TWRP look arrownd to see what is there and after your curiosity is satified reboot to system. :D

E. After all this steps are done your firmware and your phone is ready to install custom firmware, i mean CN based custom firmware.

This is it. You have a custom firmware ready phone.

------ SAGA CONTINUES -----

F. There is some new form of layout for this phone appeared recently in order to prepare the phone for more bigger custom firmware like MIUI.

This new form called "+" layout is developed by Andreya108 and is made specialy for this P780.

You can see Andreya108 work here.

Based on his work i have creeated this firmware.

Remember this firmware is creeated to support newer firmware released by this magic developers.

You can find this firmware here.

To install this firmware you must follow all the steps except D point steps. Those firmware are prepared allready with TWRP.

Hope this tutorials will help you.

Good luck.
