4. check DA,DL WITH CHECKSUM (NOT OPTIONAL)
5. press Firmware Upgrade button (NOT DOWNLOAD BUTTON)
6. now just now plug usb cable to your phone.
7. firmware flash should start.(some red and other color lines should appear)
8. 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 not less then release. All this must be done with cable pluged in to your phone.
9. after flash is done a green circle 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.
13. Good luck. Hope This Helps You.
14. Do not be afraid. This phones are hard to HARD BRICK. Most of them are SOFT BRICK.

I'll try it asap, with the stock ROM, and I'll come back to you.

OK.
I managed to flash it, after reading this post: forum.xda-developers.com/lenovo-p780/help/p780-bricked-recognized-pc-t2755207 with the ROM mentioned there (P780_S123_ROW_131231).

The prob now is that it powers ON, for less than a sec (screen flashes) and powers off again, so I guess I should try another ROM.

Any ideas of what ROM to try ?



The good think is that I managed to flash it

Funny, thing... the phone seemed to e out of batery, after the last flash. After I plugged it on my PC and it started charging, it works ok, up to now (haven't used it with a sim card yet).

Hello!
I tried to make an upgrade of firmware at my phone with flashtool, the process started and in a few minutes my computer turned off suddenly! I can boot the phone neither the reset button, neither the combination between power button and volumes + or -. If I try to connect my phone on the pc, it appears in device manager Unknown device!
I took the phone from pandawill.com,china, in september 2014, flashing s136.
What can I do?
Thanks!

Hello
For some reason it looked like I either hard bricked or soft bricked my P780 last night, because my phone is going haywire (kept returning application errors, including Google services) yesterday for some unknown reason. When I tried to factory reset it, it bootloops. Then I tried to revert to stock rom via flashing, but the SP flash tool kept returning an error when using the Upgrade. The error says that there is no PMT on my phone. Then I tried to format all of my phone using SPFT. It worked, but when I use the download option, it kept returning error No Space Error (5069) after downloading the preloader. Now all my P780 can do is charging and detect itself to the computer.
Maybe someone can help me, please?
Thank you!

Bricked, no clue whats causing it
I kinda like softbricked it by accident, but luckily i have the backup of my original and flashed it, and it went back to normal. The problem is when every time i downloaded another rom, and flashed it, same thing happened and had to go back to original backed up rom. Is it because of the preloaders that makes it unable to turn on? Can't i just untick the checkbox PRELOADER before flashing?

Oh, and mine is not original. The seller told me so.

Phone p780 doing its thing
Hello from me too....
I've been trying to fix a friends phone for days. I've followed 1 gazillion tutorials and nothing seems to work.
She bought the phone from minideal a few months back and a few days ago it started rebooting on its own.
When I got the phone in my hands it booted up and seemed to be working.
I checked in Settings>Manage Apps and noticed an app calling its self "System Service" in /data apps.
I thought that she downloaded a virus so I tried to uninstall it. As I pressed uninstall the phone rebooted but after the boot screen it said that something happened with the encryption and that I should factory reset it.
I rebooted to recovery and wiped /data and /cache.
After the wipe the phone ended up in a boot loop. It was showing the Lenovo logo then rebooting.
I tried flashing P780_ROW_S124_140403_rooted_twrp_gapps from this thread but I got an error saying BROM error S_DL_PMT_ERR_NO_SPACE
and after that the phone doesn't respond at all.
I read that if the production date is after the 3rd of 2014 you have to use another preloader and I tried with that one too since on the box says 05 2014.
I also tried Lenovo_P780_S228_ROW_PreRooted_TWRP and P780_ROW_S226_140919_Rooted_SPFlash_TWRP
I've tried flashing them again and again with and without the new preloader but I had no results...
Can anyone please help? In a few days I'm traveling back home and she'll have to use her ancient nokia that has a battery life of 5 hrs
Also, the phone gets recognized differently everytime I plug it in (I am using windows 8.1 32bit) as the following three in the pic attached.
