Additional information about the Lenovo P780 (some information might be duplicate),

This device is usually shipped in 2 software flavors
(In addition to the hardware flash being 4GB or 8GB):
1. Chinese based version - These ones are Lenovo software ROMs sXXX, sXXX, sXXX (to fill out)
2. Worldwide / English / ROW based version - These ones are Lenovo software ROMs, s119, s123.

I Saw a couple of posts online that identifies the different version of the device by the appearance of the battery markings (Though i'm not sure that these posts are right 100% of the time)

The partitioning of the EMMC is different between the 2, and as such, Images from one of the flavors cannot be flashed (using the FlashTool) onto the other(the images are just data, the structure that is incompatible is the scatter file). - You would probably get an error from the SP flash tool since your scatter file differs from the map that actually reside on the EMMC (Nothing would be flashed).

Please note that these problems only apply when flashing an image onto the device, and not using a script / existing file system (Recovery and .zip files are using the on-device file system to update roms, that should work regardless of the scatter/base)

Rebasing:
If you'd like, there might be an option to repartition the EMMC in order to cross-flash versions.
Note that there might be 'radio' issues accross different areas for as these roms might not designed to run in your region.

Preload mode - Flashing with SPFlashTool:
On the p780 There is no need to press any volume to access preload mode (I.E. Mode that is required for flashing using SPFlashTool) just hit 'download' and connect the usb to the device while powered off.

MTK VCOM Meta mode:
If u screwed up your Prealoder, Meta mode can be accessed and you can flash with SPFlashTool
Accessing meta mode is using VOL Down+power until u see on the PC "MTK VCOM Meta" or something similar.

SPFlashTool:
Both version 5.something and 3.something seem to work for me.

Dumping your own rom:
One thing I'v noticed is that if you dump your entire image (For example with MTKTools)
The preloader paratition outputted WHEN READING, differs from the input paratition file THAT IS AVALABLE ON DOWNLOADED ROMS.
Seems that when writing with the spFlashtool, address 0x0 is in fact 0x800 (ie, in the file you dump from your device there are extra 2048 bytes before the preloader paratition). If u'd like to flush a ROM you dump, be sure to check for this. It is very noticable that a downloaded rom prelaoder.bin differs from a dumped preloader.bin in the first 2048 bytes.

==
The above information was VERY VALUABLE to me when I received my phone, and this information weren't to be found anywhere gathered together.

Help..!! Phone not switching on

Hi all

I was trying to install XVIBE_ROM_v03 rom from the forum here and resulted in softbricking my lenovo P780 ROW 4 GB version.



After opening the flash tool and selecting the check box DA DL with checkbox and after clicking the Firmware->Upgrade button, i tried plugging in my cell (which is not powering on)
the flash tool doesnt proceed with a Blue and Green circles but simply doesnt do anything.

My cell is also not able to power on, is is serious, how can i revive my P780.


Please help me..!!:crying::crying:

Remove back cover, remove memory card. Near memory card slot there is red button just press it once. Now try to switch on.

Ok, I answered my own question. Flashed to ROW S123 using the PC tool and then updated OTA to S124. All working fine, baseband changed from S820 V51 to P780 V23 during the flash. Don;t see much difference between the two ROM's other than a new Video app and a few new options.

LED still not working for notifications on S124
@ashoknraj, thanks for the deatailed instructions in first post, hardest part is installing the damn drivers and there are some steps which were different for me to get it working:

- Download the drivers and install on the PC using the exe tool in the package. Once installed, ensure USB debug mode is enabled on your P780 and that it is powered on and then connect to your PC using the USB cable. The drivers should pick up the P780 and install the device.

- Next, power off the P780 and then connect it again using the USB. The PC should again pick up the P780 again and you will see it briefly appear as an unknown device in the Device Manager. However, no need to right click and update drivers as you have already installed them previously so just let it search automatically for the best driver to use and it will finish installing. Once done, disconnect the P780.

- Run the flash tool and only connect your P780 after clicking the "Firmware->Upgrade" button. You will see a message in the status bar of the flash tool that says "searching" and then COM once the P780 has been found. If it stays on "searching" then it means the USB drivers haven't been installed properly and you need to redo.

- The whole process to flash takes about 7-8 minutes and a sqaure with a big green circle will appear on the Flash tool once done. Disconnect your P780 and power on as normal. The first boot takes about 5 minutes so don't panic, it will just show the usual Lenovo boot screen.

- Before rooting or doing anything else, go to System Settings -> All Settings -> About Phone -> System Update to update OTA from 123 to 124.

stock ROW or SLX? why?

bootloader


I just bought the Lenovo P780. I'm really happy with it so far. Just one issue, the bootloader is in Chinese. I'm not very good at reading Chinese. Does anybody know if there is a translation of the bootloader anywhere? I've been google diving for two days with no success. Even just a translation of the pinyin would be very helpful. A custom bootloader would be better. Thanks friends.
