[Q] Lenovo P780 Call quality issue - Lenovo P780

Hi xdadevelopers ,
I have purchased Lenovo P780 handset 1 year ago.
The issue is that whenever I speak , the person at the other end is not able to hear me properly.They complain me that my voice is cracking ...
I also observed that in such case if I use the microphone /headphone set , the person at the other end informs me that the sound quality is slightly better.
I had refered this complaint to authorised Lenovo repair centre & after 15 days , they returned me informing that they have changed the mother board .
Still the issue was not resolved.
I have changed sim cards but still the problem is the same.
model : P780 _ROW
Android version is 4.2.1
Baseband version is P780 V23 ,2013/12/06.
Please suggest .
Thanks.Regards.

You coul try to change the modem software. To do sutch thing you mudt root your phone and install custom recovery like twrp or cwm.
To root your phone use framaroot.
To install custom recovery look in the development area and you will find there alot of custom recovery.
To change modem software look for my post called : How about some modems. Located in general area.
Good luck.

Hi again .So i solved the problem like this .After of hours of research i found out that the mobile is the JIAKE GT I9500 L.So I downloaded a rom from "needrom dot com" ( cant post links yet, new to xda ) and flash it powered off with sp tools .phone is ok and rooted .The problem is that when i make or receive a call, the other end of the line hears only bzzzzzbzbzzzzzzbzzzzz something like you hear if you have a mobile phone very close to a radio .I have tested hands free and Bluetooth and is the same .I tried different roms but again the same .So its not the mic of the mobile .Any suggestions ?
i have exactly the same problem
hi
mrfield, i have the same problem with my phone JIAKE GT I9500. Strange noise (bzz) when receive or make a call, but sometimes it's good.
Do you have found a solution to solve it ?
Perhaps a setting in mobileuncle or a good rom ?
Do someone knows how to solve this very big problem ?
Thank you very much in advance
It seems i have found a solution to avoid strange noise
Hello
It seems i have found myself a solution to avoid this awful noise when make and receive calls.

If someone is interrested to have this solution please reply me here and i want him make his tests too and says his opinion.
Thanks

In spflashtool I can see it has a mtk6582.
It says the display is a ALPS.KK1.MP1.V2.11
Thankyou in advance!!

That's a fake phone for sure. It exists as "JiaYu G5S+" also on AliExpress. Same front with no brand name (first sign of a fake) but different brand names on the back cover. I bet you got it in a blue box also labelled only "Smart Phone"? Funny phone really. I wish I had one to play with to see what kind of apk's it contains to fake AnTuTu score and device info. It also fools CPU-Z to display totally fake hardware info. Did you try CF-Bench? That phone exists as a no fake 80-90$ Elephone P6i. Elephone has a HK based homepage with ROMs and links to other ROMs. Possibly also a MIUI ROM.

http://service.elephone.hk/forum.php?mod=forumdisplay&fid=98#.VF0Y6EtPY7Q
Here is another thread about that phone on this forum:
http://forum.xda-developers.com/android/help/jiayu-g5s-elephone-p6i-guide-t2931900
See Mijue M5000
Hi, I think is the model M5000 Mijue
Actual specifications are:
- MTK6582 Quad Core 1.3GHz
- Android 4.4
- 1GB Ram 8GB Rom
- 5.0 Inch FWVGA 854 * 480 IPS Screen
- 5.0MP Back Camera 0.3MP Front Camera
- Support 3G, GPS, WIFI, Bluetooth, Play Store, Multilanguage, etc
I'd be interested in a rom for this model.
Greetings.

Yes, I said it exists as Elephone P6i, wich has those specifications you list. If that hardware is packaged under the name Elephone or Mijue doesn't matter, the inside is manufactured by a few larger OEM factories for all such brands in China. The same inside as the fake Lenovo S850C in this thread exists as Landvo, Star, KingSing, Zoppo and so on also (with very few small variations). These low budget smart phones usually have that in common that a benchmark app will label the manufacturer as "Alps" and/or the firmware as …alps…
Like I wrote in my previous post in this thread, if you have that fake Lenovo S850C you can flash the ROMs for Elephone P6i from the links I posted. There is even a MIUI ROM for that phone, or at least that is what I have been told by people in the business in China. Use Chrome with autotranslation on if you come to a Chinese page (unless you speak Chinese).
Thanks
Thank you very much.
Really I am very grateful with your information and I can get down to work and take advantage of the device.

Thanks
Thanks for the stock rom.
I have not read much about how to 'cook', but I have done some testing, I flashed the system.img other devices and some have worked, not with all the operating hardware, but have started.
Now it is studying to prepare a rom for the device (and I managed to put the CWM recovery v5).
Thanks for your help.
bricked android
help i need "rom" for this phone

my android bricked - no react ,no power
Sorry, I have not identified your model. I do not know how to get it working again.
If you made the backup phone can try to recover it.
To put the rom, it worked for me connect my phone to pc without battery and hold the volume +, hold immediately after connecting the battery button. MTKDroid recognizes and begins to download the files.
Luck.
@kele6a
What did you do with your phone when you bricked it?
That's a fake Lenovo for sure but in a new version that I have not seen before. It has another home button than the usual fake S850C.
But I guess it's the usual fake S850C hardware with a slightly different exterior. It looks more like a Samsung ripoff than an iPhone ripoff.
You should try to flash the ROMs in this thread or go to the Elephone homepage and look for info there. There are instructions for flashing on the Elephone homepage also.
It's very hard to really brick a MediaTek SoC. If I guess right your phone has a MT6582, not a MT6592. It can be an older MT6577 also and then the MT6582 ROM in this thread won't work.
Install the proper MTK drivers in your Win PC and then use SP Flash Tool for flashing (better than MTKDroidTools). The phone must be switched off (not standby, it must be really off) when you flash. Remove the battery to be sure. If you flash the wrong ROM you will only soft-brick the phone, so no big worry.
There is more info in the fake Jiayu G5S+ thread (also the same as Elephone P6i). I suggest you to read that whole thread. You have everything there (probably).
http://forum.xda-developers.com/android/help/jiayu-g5s-elephone-p6i-guide-t2931900
I was lucky to first make a backup with MTKDroid Tools and prepare for FlashTools, with that could resurrect.
I tried to put the rom of elephone p6i and the phone was unusable. Not even picked load, I thought it was broken.
With no reference model I had, I searched several forums as people did to 'revive'. Trying things that I read, and end with a mixture of several got to come back to life.
The most difficult for me is to find ways that FlashTools should recognize the phone to download the rom. From that moment the phone began to work, and now I'm reading to cook a rom for the device.
You have to keep in mind if you use windows 7, XP, windows 8.1 ... to install the drivers, then see which way the mode for firmware (dfu) is activated on your phone ... From what I read many models share the method to enter dfu, look at my previous post and try to see if it works.
If you do not have the backup, I think the first would find someone who may have or who has risen somewhere.
Also if you can find the phone that is clone, you can serve the rom of this. I think that is where you should focus your efforts.
I started looking for the info of MTKDroidTools (MTK6582, 1Gb Ram., android version, kernel version...), then added the type of display you thought was (FWVGA), ... and reviewing photos phones until I gave with which was the original ..., but I don't found a stock rom for this phone. I also helped another user uploaded a copy of the rom terminal in the post (thanks morpheubr).
All this adds patience, I had the phone as you and the end has come back to life. Good luck.
Hey probably I have same fake S850c, i try some ROM and now phone is unusable and I dont have faked rom copy if you have it can you upload it somewhere.

Did you write down the original firmware version?

How to unbrick an MT6582 unknown manufacturer missing stock rom?

Hello , I am sorry if posting here is wrong but I have got to craziness state searching how to unbrick my tablet.
I bought a tablet from china and wanted to look at how to remove the menu from it. During this process I ended up bricking the thing.
It doesn't turn on . When connected to computer it does the usb sound on and off.
What i know from the system is
mt6582
Andoid 8.0
128GB ram
Build number - ALPS.KK1.MP1.V2.36
model nr - YT886-12
Kernel 3.4.67
I know this because I bought two of them but when I opened them both , the motherboard is slightly different .
The phone/tablet is recognized as N90 which I have no idea what it is.
Please help in any way possible cause I am about to break this thing apart. I have lost 4 days and nights looking for an answer.
Thank you in advance.

Looks like I am trying to fix the same device.
I brought mine from China also because of the spec didn't know the firmware was a custom install and doesn't even show android system webview even though Google play store says its installed but it not compatible. I just need a ROM that will work with my device and whatever else I need to put it one my tablet. Normally I can figure this out but I have epilepsy now and it to hard for me to focus.
