Hi. Your phone is rooted? Any custom recovery like TWRP?
What have you done to the phone?
Did you moved to another region?
By the way... in what country are you in now?
So many variabiles?
Try and dial *#06# and tell me if you see the IMEI's.... Or invalid. This is a precious information.

Thanks !!!
When dialing *#06#, I can see 2 IMEI's in my phone.
The issue started when I was using the phone in the same reason, Mumbai in India, however now I have moved to another.
The phone is not rooted neither any custom recovery tried.
As far as I can guess, the problem started when I updated phone android version from Jelly Bean to Kitkat however I am not sure.
Should I try downgrading android version of the phone. Please mention how to do that. What else should I try.
Thanks in advance,

Hi.
Ok if you see your phones IMEI is good.
Lets start with first steps:
1. Beacuse this is your last official update to your phone and is quite old you could root your phone.
2. Rooting tutorial with tools and istall TWRP here:http://forum.xda-developers.com/lenovo-p780/help/rooting-tutorial-kitkat-t2835605 . Use TWRP 2.8.4.0 REV2 ROW if you have ROW version of your phone.
3. Read first act later.
4. After rooting and TWRP install, go to TWRP and do a full backup. NOT OPTIONAL. Save backup to an SD Card.
5. Now go to this post and download all Europa Modems: https://drive.google.com/drive/folders/0B2ORIgaV4iacaFFaM2pnX1A2Rnc
6. Putt all those modems on a folder called Modems.
7. Reboot to TWRP. For this part go to Magazin Play and install Reboot Recovery. Give root rights and reboot in to the recovery.
8. After you are in TWRP go to Install option, browse for your Modem folder, select one modem and swipe to install.
9. After install do not wipe to factory reset. Dont need this factory reset in this tutorial.
10. After install reboot your phone in to system and wait for the signal to appear. Iff by any chance is not working , the install of the modem procedure must be repeted, till one of those modems works.
11. Do not hurry up. Let the phone to find the signal for a minute or two. First time the signal will appear more slow.
12. Good Luck.
I have the same problem. However, my phone doesn't detect SD either, so I can't do the procedure described above. Everything was OK, util I did factory reset. I can also see my IMEI.

In stead of using the sd card, use the imternal memory of the phone.
What happened? Why did you reset the phone? Did you flashed another firmware?

Great thread! Flashed an old P780 4GB CH late 2014 with the AOSP ROM the other day and the GiffGaff SIM in it stopped getting a signal. Just flashed Modem_P780_KK_V.103.zip from the Modem Europa folder and now both the GiffGaff and Vectone SIM cards are working perfectly once again.
Thanks stympy!

My phone also encounted the same problem after flashing Custom ROM from needrom.com. Did you make a full backup of your phone? If not then it's too bad and you might need to sent your phone back to service center.
You can try this link for tutorial and see if it works to recover your IMEI and baseband, if not your last resolution is send back to service center.
http://lenovop780en.blogspot.ro/2014/01/faq.html
And after your phone back from servicing, next time remember make a full backup incase anything goes wrong. Post #3

Hi,
I think u need to flash your rom once again.
Use flash tool to install the same.
But before that connect your phone
and go to format- format whole flash-ok.
For this u need to select the scatter file from your firmware.
After this download your firmware( not firmware upgrade)
also click on check box for D/L.
After flashing new firmware you need to use above steps which I described earlier.
Good help you.

Hi I wonder have you resolved your issue or not? Actually I found a consider temporary solution.
With your phone rooted, using any root explorer, navigate to /data and copy the nvram folder to your memory card (as a backup). Then delete the whole nvram folder in /data. Wait a while, your phone should have signal and baseband already. If works let me know, I will tell you what to do next step.
Hi, I repass two phones in one, can not find a signal. I do not know what is meant by this icon:

Hi everyone,
This is my first post/question on this awesome community. I have a lenovo p780 8gb, the phone was working absolutely fine until yesterday. Now I am not getting any signal coverage whether it be 2g or 3g, I didn't do anything to the phone, no root, no physical damage etc. I tried searching for a solution but all effort in vain. I checked with different sim cards, tried the factory reset but the signal never came. I also tried to upgrade the firmware but after downloading the update data of 11gb the phone entered recovery mode and the update failed. I will post the complete error message if any one asks. Please help, it's very very annoying. :crying::crying::crying:

Hi. You must tell us more about your phone. Like: are you in custom ROM? Your ROM is ROW or Chinese? Do you have Custom Recovery or Stock? Have you moved in anorher region then where you tested the phone, because the modem would not recognize the network type?
Ohh... And 11gb of update for your phone does not exist. Max 1gb in custom ROMS.

Hi thank you so much for replying, As to answer your question everything is stock, the rom, recovery etc. My rom is ROW. I didn't change my region, the signals just went missing without any reason. I am sorry about writing 11gb update I wanted to write 11mb. I havent rooted my phone and havent tinkered with it in any way. The phone is 3 months old. Also the phone is showing a system update of 11mb but when I download it and enter into recovery to apply it the installation aborts. I really have no idea what is happening. It's really frustrating. If you have any questions please let me know.

This is realy strange indeed. I think your phone is in warranty time? Iff your phone is not rooted we cannot do mutch! Maybe you should go to a local service store.
Yeah it is, if you have any kind of solution then I can root my phone. I tried to install a different modem but the installation aborts without giving any kind of error message.

Yes. Because your phone doe not have a custom recovery.
To root your phone you can use Framaroot but you are going to lose your warranty and this is not good.
After that you can install a custom recovery with mobileuncle tools and then you can patch a new modem.
OK , can you share a link about how to install custom recovery in lenovo p780, and a list of few modems. It will be really nice of you. Thanks

Hey there all fellow XDA members, i have encountered a problem with my p780 8gb, i bought it from Malaysia in the beginning of the year,
this morning i woke up wondering why the alarm didnt go off and saw my phone stuck at the boot screen.
I didnt do anything but update the phone a week ago via the lenovo updater to kit kat, i rooted it in Jelly Bean but didnt do it yet when i updated to Kit Kat, ive tried resetting, clearing cache & it doesnt work, im not too sure what to do but i was thinking of going back to Jelly Bean, if anybody has links to a good rom that will work for me that will be really awesome.
Thank You ! :good:

Much appreciated once again ! I was looking for a guide to flash and i was wondering if this is a good guideline ? Anything im missing ? Thank you so much man !!!
Step by step guide to Flash stock rom:
1.If your phone is not already soft bricked, back up whatever you want. External SD card is fine. If your phone is soft-brick then say goodbye to your data and skip this step.
2. Uncompress all the files you downloaded from this thread into a directory where you can remember. Including the ROMs.
3.Shutdown your phone if its not in a bootloop. If it is skip this step.
4.Open "Device Manager" on your Windows PC.
5.Plug in your phone through the micro USB cable. A device will show up for a few seconds in "Device Manager". After that, it will disappear again!
6.Recognize the device tree where it appeared, and wait for it as you unplug and plug in your phone again (if bootloop, its automatic!)
7.Catch it with a right click as it appears! Then choose "Update Drivers" and pick the directory where you uncompressed the drivers you downloaded above. Its ok if after catching it the device disconnects. You only need to install the drivers now.
8.Assuming the drivers are correctly installed, run the Smart Phone Flash Tool.
9.Click on scatter-loading and choose the scatter file "MT6589_Android_scatter_emmc.txt" of the ROM you want to flash.
10.Make sure the checkbox "DL DA All With Check Sum" is CHECKED
11.Click on "Firmware->Upgrade" button.
12.Plug in your powered down phone via the USB cable again. See it flash.
13.When a big green circle appears on the screen, your are done!

I see you said if i want to change from stock to custom but you gave me stock images ? Confused
I take it S124 is the ROM before the kit kat update, think i would prefer a stock phone for now, do i just download the stock rom with SP Flash tool, has anything else changed ?
Thank you. Regards

Hi. You must reflash again your phone. Because in this moment your preloader is messed up you must reinstall drivers.
After drivers reinstall you should be abble to flash again.
Tell me if you have problems !

Hi. You must reflash again your phone. Because in this moment your preloader is messed up you must reinstall drivers.
After drivers reinstall you should be abble to flash again.
Tell me if you have problems !
Good Luck.

I could not finish the reflash using MTKDroid tools.
Hey Stympy,
The phone stopped responding. When I switch on, it just shows Lenovo logo and sticks there. No further response. It doesn't go to recovery mode (power button+ volume up)!
I think I am in a deep s**t now.
It seems the phone is shut down from inside!
Can you please get me out?!
Thanks a ton!

I downloaded the files as suggested in your post.
However, I could not flash anything into my phone. So I tried to use MTKDroid tool to open the phone in TWRP recovery mode and installed the TWRP_v2.7.1.1_P780_ROW_KK_Corrected.zip in recovery mode. After this, I rebooted into recovery again, and tried to install the P780_ROW_S226_8GB_KIT_KAT.zip thro recovery. But that ended in failure.
When I try to flash the ROW using SP FLash tools, this is the log I am getting. I do not see any action in the tool except all the options grey out! I had installed the USB drivers and my phone is being detected in the MTKDroid tool, but not in the SPFlash tool.
Now the phone is starting, but none of the modules work, like sim card, contacts, apps, store, etc.
Any suggestions?
Thanks a bunch!:good::good::good:

Dear Stympy,
After trying many ROM and updates, I could finally flash official updateota from Lenovo, which seems working.
My phone is up and running now with the KitKat 4.4.2 P780_ROW_S220_140722.
However, the internal storage seems to be a problem in this version. It says the internal memory is full and I am not able to access the internal memory. Is there any way out? Also if I flash the ROM given by you, will it work?
Thanks a lot for being there!:good:

Flash S226 and OTA update till S228 and see what is going on ! Be careful to flash the firmware you need !
I do not know if your phone is 4GB or 8GB. Here is the firmware.
Good Luck.
UPDATE UPDATE UPDATE! scroll to the bottom if you wanted to know what happened to my phone before it get fixed.
....
I was able to resolved the problem and was able to return back the BASEBAND - PTTYCMD1 missing - dev/radio missing and most of all missing IMEI without using any image from other sources...
With all the tools that i used such as MIUI, SN WRITER, MOBILEUNCLE, AT COMMAND via ADB, NVRAM IMAGE from other users, MTK DROID TOOL (which will not work since baseband and META MODE is damaged), the only thing that was able to fix this is the SP FLASH TOOL with the right phone drivers installed for p780 such as the USB VCOM which is very important!
We are all aware that some of us have tried everything to fix it... I will tell you how..
Just a quick tip: A phone with no BASEBAND and damaged meta mode will not be resolved using restoration tools but only SP Flash will..
Simple - but deadly steps... You need to full format the phone and then download stock ROM using SP Flash tool. But before you do that make sure that the VCOM Drivers are installed. (i saw it being used when the phone auto-detects and SP Flash downloads the stock rom back to the phone).
After restoring the phone back, the baseband is there already and you need to use the SN Writer tool and add the BT,IMEI,Mac Address of the phone. Restart and everything will be back to normal.

Model: Lenovo P780 8GB ROW
O.S: Kitkat
I followed one of the instructions on how to root at this website:
http://forum.xda-developers.com/lenovo-p780/help/rooting-tutorial-kitkat-t2835605
After doing the steps below... The phone does not detect IMEI anymore. It is saying invalid.
I tried using MTK Droid Tools -> does not work
MIUI: does not detect phone in meta mode anymore (meta mode is gray when phone open, there is no text that says phone is in meta mode.)
MobileUncle IMEI Restore: I have a backup of this, but after rebooting it still does not have the IMEI.
SN Writer: same with MIUI, it does not detect phone.
tried reflashing back using SP Flash tool: but when I reverted back to jellybean the IMEI is still not there...
Maybe any masters could help me. Lenovo P780 is a nice phone. But i never thought of running into this type of problem wherein i dont have a backup of NVRAM.

Hi there. Post here some screen shots of MTK Droid Tool when you plug the phone.
Look in to the /dev/radio/ and tell us what you have in there.

Hi Stympy,
I already downgraded to Jellybean but the problem still persists. The DEV/RADIO folder doesnt have anything inside it using root explorer.
I attached a screenshot of the MTKDROID Tool Information about my phone.

:crying: stympy you broke my heart after i read your comment. I am thinking of seeing a different reply. hahaha.
Anyway I hope you find a solution. i tried searching already cannot seem to find answer to my problem.
Indeed pttycommand is missing ,reason mtkdroid wont work properly.
Even when it goes to meta mode its just gray(?)
The only problem with this phone is it cannot detect any sim right now.
wifi, bluetooth all other functions are working.

Hi again. Here is alot of information about lost NVRAM.
Maybe this will help you.
I did not readed all! I dont have time this days!
If by any chance find something good and restore IMEI share with others and an little tutorial will be most then wellcome!
Use Google Chrome for translation or Yandex translator.
Good luck.
Thanks for your reply stympy. I hope others who has the same issue share their story as well.. regarding how they were able to fix it.
I read it, though english translation was bad. I am scared doing what they wanted to do like cleaning the NVRAM by formatting the phone and checking only the preloader in SP Flash tool and then downloading back an original rom to P780, and start from working back on the NVRAM like adding the Btooth, WIFI, Serial, IMEI codes back again.
The only problem on this phone is the IMEI. Wifi is working, bluetooth as well.
Sad part is pttycommand is missing. The reason why MTKDROID was not working. Even the other tools cannot detect phone in META MODE because its just gray and no words saying tthe phone is in meta just like before.
Hi Stympy,
Is there a website on how to format the phone using SP Flash without the consequence(s) of bricking it? I want to format it and flash stock rom again and see if the IMEI will work back again.

Hi. Flash tool has an option to format internal memory! That depends on flash tool! The tested flash tool for Lenovo p780 are uploaded in my post Rooting Tutorial for KitKat.
DO NOT USE OTHERS! YOU WILL ERASE NVRAM!

I used other flash tool when i rooted my kitkat based on your instruction that might have caused this issue.
There are 2 flash tools on your tutorial.
SP_Flash_Tool_v5.1352.01
SP_Flash_Tool_v3.1304.0.119.rar
What am i going to download?
Do you have a tutorial how to use the flash tool you posted in formatting internal memory?
Thanks Stympy

Thank you very much stympy. I will be looking forward for that.
I think the only way to restore IMEI is to restore using a backup copy of the firmware, probably using mtkdroid tool to create a backup.
If you are on P780 ROW 8GB Model. Maybe you can help by creating a backup copy of everything using mtkdroidtool and posting it here OR if you know a link where to download let me know.
Mine is damaged.. cannot create backup.

Hi all. For those of you who flashed wrong firmware and your IMEI are gone look what happent to me:
1. i flashed a custom recovery who errased my IMEI. That happent because the recovery was 7.5 mb instead of 6 and i was "blind" and careless and stupid and...nevermind
2. after restart surrpriseee.. no IMEI.
3. allmost total panic here.On MTK Droid Tool 2.5.3 IMEI NULL paniC again, and my worst nightmare PTTYCMD1 ERROR FILE NOT FOUND. Panic panic panic, used hard words #@$^%&(&&%$%& words alot.
4. after a little cooling i reflashed my old TWRP back and started to look in my computer for the firmware i allready have installed wass Baralajbi v6 (i like the partitioning of internal memory) firmware from needrom. Before that i tried to restore the NVRAM from TWRP. It did not work. No IMEI has appeared after restoring with TWRP.So i have rebooted the OS back and i immediatly go to /dev/radio where the PTTYCMD1 and the folder was empty.Again *&^%&$%^#^%#%^#^&(*(^* words.
5. Then i have reflashed Baralajbi firmware and after flash i have installed Root Explorer. Again i immediatly go to /dev/radio where the PTTYCMD1 and the folder was this time all the files were there.
6. So if this file PTTYCMD1 is in the /dev/radio folder you can restore your IMEI safely with any tool.
7. I hope this little problem of mine will help you other users to restore your IMEI.
Hi Stympy!
Can you give us a link or instruction how to install Baralajbi firmware?
Worth a try.. have not formatted my phone yet... I am seeing the solution here.. I want to try it!
UPDATE:
I notice a lot of links pertaining to Baralajbi firmware p780 row 8GB.. can you post the link of the same firmware you used?
