Hi All,

This also solved my problem (maybe we should add a thread for post-0414 phones.)

With the modified file we can flash multiple roms (checked about 5 now). But I got a question. How to flash a custom recovery on this phone. I tried everything and almost every recovery(CH/ ROW etc etc) i could find, but the phone keeps booting into the normal recovery and not into TRWP, CWM, (and an other one i forgot the name ).

Tried to install it with MobileUncleTools, but i cannot get a custom recovery on the phone.

Anyone got a solution for this (except flashing again, (not a big problem but without would be beter)

Greetz,

Michel

btw casaben what did you mean with linking uboot to the LK file, the roms i tried works without that (i think) because i really don't know how and why ? (and i'm asking to learn that, so i hope you can explain why and how)

Hi. What ROM do you use?
is it rooted ?
Custom recovery instal depends on that.

Hi I'm running P780 4.4.2 1423 ST Pure GAPPS ROOT (found on needrom),

i know this rom doesn't have custom recovery but i hoped it could be installed after flashing.

Could we switch the recovery.img before flashing roms on the phone just like we have to do with the preloader ?

Or only flash the recovery.img with the flashing tools ?

Yes you could. Just replace stock recovery with custom one.
I recomend TWRP from life ROM that you will find here:https://drive.google.com/folderview?...TA&usp=sharing
Extract from archive CHINA ROM - RECOVERY.IMG; COPY ; replace your stock recovery with this one;
Flash;
Enjoy.

today i tried to flash my P780. The Build-Number of my phone was P780_S136_140306.
I flashed ROM P780_S135_130917_rooted_twrp_gapps with Smart Phone Tools and after that my phone was dead.
I flashed this ROM because i want to flash the ROM AOSP-4.4.2-v.1.8 after that.

Thx stympy for your tutorial to bring back my phone back to life!

I donīt know if my phone is chinese or not. There is no date on the battery, only chinese letters.

I need help to flash ROM AOSP-4.4.2-v.1.8.

Thx
So.. lets see.. Your phone is chinese, thats for sure.
On your box that came with your phone you should see the date of fabrication like 04.2014 with some chinese letters.
This tipe of phones are called SPEED like this: Lenovo P780 Speed. They have done some modifications.
After you flashed your stock Firmware, must do this steps:
1. install MobileUncleTool from google play;
2. download a rooting tool; the firmware must be rooted;
3. download custom recovery TWRP or CWM;
4. put the custom firmware on your internal storage;
5. open Mobile UncleTool; go to recovery update select recovery and flash(update).
6. tell me iff something goes wrong;

Default Reboot Loop

  • Phone Model : Lenovo P780 ROW 8GB version
  • Country of origin : India
  • Current Firmware : P780_8G_ROW_S124_140403
What went wrong : I was trying to install Lewa OS stright from Lea OS website via custom TWRP recovery. Took a nandroid backup for precaution and then installed LEWA OS.
Installation was not succesfull as it tried to repartition phone memory. Any ways fortunately i had the backup handy so i restored the phone to its early state. Restoration was also succesfull. However when i rebooted the phone after restoration it stuck in reboot loop.
Symptoms:
  • Phone vibrates with no display
  • NO boot animation. its gone
What Works :
  • I can flash custom TWRP or CWM recovery on the phone.
  • Can use the phone normaly if i use the hardware reset button to manually switch off the phone completly
  • Can install any compatible ROM, however al end up with same reboot loop when first turned on.
If some one could guide me on how to repartion or reformat the phone from scratch using any flashing tool, i will be thankful !

HI. Look what you must do:
1. Download your firmware from the development posts and flash with Flash Tools . Reboot.
2. Install Mobileuncletools
3. Download Latest Framaroot and root your phone
4. Install custom Recovery TWRP or CWM.
5. Restore your Backup.
6. Tell me if something goes wrong.
7. Good luck.

Sent from my Lenovo P780 using LiFe v.07 and TWRP 2.6.3.0.
