same problem with me......... :crying:
I just have IMEI but not otherss..
Hi guys,
Please help me out as i am stuck with the data settings on my phone. When i bought the evo 3d phone configured with reliance, everything was working well. Suddenly, my data network stopped. I contacted the seller and he gave me the new NV dump file stating that the older one is no more useful. He also told me to flash it on my device. He told me that i can do it using cdma workshop.
Can some one explain me the procedure for the same?
Your help is greatly appreciated.
Please someone help me, I dont know if this post is allowed here or where to put it. Im just desperately needing a help..
I've flashed my rom, everything is fine. I found the right rom for my device.. Everything is working fine except the sim card.. The problem is, my phone is detecting my sim, but I dont have "signal bars logo" in upper right and my Sim Management is grayed out.. I cant access Sim toolkit too.
I got my Imei number and its not "null" or "invalid".
I just dont know why theres no network.. :'(
Or this problem, when i tried wiping the data and cache using recovery mode, the samsung logo is vanished and the phone are able to detect the sim card, but since the imei number is "null" or "invalid", I dont have signal. So i tried restoring my imei and everything is fine. I got signal.
But the problem is, When i switch the data on, Im only getting an Edge signal(E) and not WCDMA(H). When i tried to change the setting by making it "WCDMA only", my signal lost.
Its like, the phone lost its capability of having a 3G signal.. How to fix this problem?
Please, someone help me. Ive already spent 3 days of searching but still no solution.. Please please someone help..
See my device's info below, and if ever someone knows or someone has same rom of my device, please send me a download link..
Thanks in advance!
Heres the screenshot and see, I dont have signal and sim management is grey and cant open..

Hi!
I have problem with my lenovo p780 4gb Chinese version (after 04.2014)
I am using vibe ui 2.0 (row version from sympty's thread)
I flashed couple Roms to find my favourite and probably messed up with the nvram.
I was having problems with no signal, nvram error in WiFi ect.
I couldn't restore my imei (done with mobile uncle but after reset the problem apeard again).
Decided to recover nvram.img but as I did not have my own backup I used one uploaded by sympty. (Before restoring nvram made a backup of my own messed up nvram, just in case).
After recovering sumptys nvram the problem with imei and nvram error in wifi disappeard . I noticed that I have symptys imei so I overwritten it with my own using moboleincle.
The problem is that I still get the network problem. No signal at all. Tried many modems also the one that have been adviced to me here (the one created by xaep).
Do You know what can cause this?
I noticed that in mobile uncle radio information the signal is not floating. Once it worked it was floating now it is still and shows 0 db 99 and.
What else could I mess up and how can I fix it?
Thank You guys in advance.

So that means that I did not rewrite imie properly?
Also, I noticed that IMEI on the baterry is diffrent than IMEI on the back of the box. My phone have been in service in China, maybe they've made a mistake?

This is strange. At least one of the IMEI'S from the box must be the same with the IMEI from the accumulator. They could switch the box on the service store, i think?

Yes probably You're right.
Soo does it matter wchich imei I will use? The one on the box or the baterry one?
Also I am still facing the problem with network. Tried many modems. And now i eaven get the problem with sim card (mmi error).
I changed the nvram for the one i got from this forum.
Can't really rewrite imei with sn writer but managed to do it with mobile uncle. (It changes, but after factory reset it goes back to the imei i got when changed nvram).
I don't really know what else could that be. Maybe it is the rom?
I really like this phone, but I am starting to think of getting a new one without network problems.

Hi. It does not matter what IMEI you are running. It doe matter to have one .
With network problem it is the same! If you dont have IMEI you cannot acces any GSM network. You can change all the modems, if you dont have IMEI your phone cannot acces network.
And yesss.... MobileUncle Tool is an temporary solved problem.
I did not encounter this proble myself. I have saw this problem to others.
From what i have read i saw that this problem could be solved with an older firmware like s119, s123, s124. Dont know how but some of the users did write the IMEI for good.
You can change only the motherboard, or change all the phone and this one use it like power bank, nice agenda, or other uses.
Good Luck.

Will try to go back to the older firmware like You said.
Basically if it doesn't matter what imei I have, than it is not the imei problem, because I do have imei after factory reset, only it is probably Yours (because i restored nvram uploaded by You ;D).
In such a case, maybe the firmware will help.
Hello I have Zenfone 3 Max ZC520TL. Recently, I bricked the Zenfone. Luckily I figure out how to unbrick it and it worked successfully. The inconvenient that I have right now is no network signal due to unrestored NVRAM and NVDATA. So what's the problem here? It's impossible to root (I tried a lot of methods and nothing), I cannot open the bootloader (open the bootloader to install the TWRP and restore) due to null Serial Number (I guess). So I need to restore those Nv's (I have those Nv's saved, backuped) to put on work my network signal and data
So, if someone knows how to solve this, please help me
Thank you!
