Heya,
I bought a Sophone V 75 (an iPhone 4S copy, almost identical to Goophone Y5).
It is an andorid based phone
Naturally the OS was horrible, all in Chinese.
Well I followed instructions here http://forum.xda-developers.com/showthread.php?t=1896242 how to root the phone.
Then I used the Rom manager app to change the recovery file and install the ICS 4.0.3 ROM for the Sophone V75 with working Google Play Store.
All good until I realized that I have no data connection what so ever, not even edge (not to mention 3G /4G).
In addition, the wifi reception is horrible, and I have to stand next to the router to get any data.
(I live in Finland, if that has anything to do with the poor connection [i.e. an ICS made for the Asian market etc.?], I am a complete noob in modifying / rooting etc.)
My question:
1. Can I install a radio image file designed for another device (naturally there isn´t really anything made for the Chinese knock-off)
2. Can I use the Rom manager to boot to recovery, select and flash the radio.img file that is suitable. Or do I need some special software for that.
I basically now have a phone whit great specs but which is useless due to bad wifi and no data connection! (paperweight) :crying:
Thanks for your input!
NO 3G or DATA CONNECTION? - TRY THIS!

HI there!
I also flashed the Android ICS 4.0.3 version and I did NOT have 3G or DATA CONNECTION
working after this update???
(I used the Recovery.img I uploaded on this page to flash phone to this ICS and it is available below on this page:
http://forum.xda-developers.com/showthread.php?t=1896242&page=3
1. Put this on the root of your internal SD card of your Sophone-Godphone V75.
2. Then to flash the phone, turn OFF the phone, and connect Sophone V75 with USB cable to computer.
3. Press POWER ON and VOL+ BUTTON at same time and hold for 7-8 seconds!
The Apple boots for some seconds and after this a blue RECOVERY MENU appears in english!
4. Use the vol buttons to scroll and confirm your choices with Power button!
MY SOLUTION TO MAKE DATA CONNECTION WORKING:
The mistake I made was to edit SIM MANAGEMENT inside Settings and I changed the title of the Operator
from TELIA(default name) to HALEBOP (Halebop uses TELIA as netprovider) and also I edited(changed!)
and wrote the cellphonenumber inside SIM MANAGEMENT under "Enter Phone number".
I think it may be this problem if you insert your own titles and number and the phone gets mixed up?
I tried after this to insert APN settings from the Operator HALEBOP(Sweden)all the time but no success!
At last I got tired and tried to flash to other firmware version Sophone V75 but it did NOT work either??
So here I was stuck with this ICS Android 4 with NO DATA CONNECTION and not possible to reflash!!
HERE IT GOES:
So only thing to do was to TURN OFF the phone and use the Recovery.img to boot into Recovery Mode.
As I described in the beginning of this reply!
In this Recovery Menu I first chosed to:
1. Wipe Data/Factory Reset
after this was done I chosed:
2. Clear Cache
and after this:
3.Reboot !
The phone rebooted and took some time and after this it started up and my default Telephone Operator
TELIA was titled under SIM MANAGEMENT as default after this factory reset and clear cache!
So I DID NOT change anything after this and just simply went into SETTINGS/ SIM MANAGEMENT
and pressed Data Connection and chosed TELIA inside and it WORKED!
The letter E showed up directly up in the top of the display screen beside the "signal strength" icon!
So I recommend to do exactly as I described and hopefully your V75 will be working with DATA CONNECTION!
GOOD LUCK!
I have dual sim Lenovo P780.
PROBLEMS:
DEFAULT SIM SLOT (supports WCDMA and GSM) - works fine only on WCDMA /3G. When I put it on "GSM only" it goes dead - "connection error", "emergency calls only" and all that.
SECOND SIM SLOT (which is GSM only) doesn't work att all.
The sim cards are fine (checked it on other phones).
I also put other sim cards in my phone (and swich them around) => same result - sim 1 only 3G, sim 2 dead
Both of them see the providers but have no signal on gsm/2G mode.
Thanks,
Same problem here?
Any workarounds yet?
Cheers
i have the same problem and I cannot find a solution...

I cant find another one, only for S920.
This is my P780 (S920, S820 are compatible) modem collection :
modem P780.zip
http://www51.zippyshare.com/v/55282913/file.html
But:
1. For Chinese model I recomend V51 or V52 ( on the battery is written in chinese). Both sims works but no WCDMA 900 band( chinese version doesnt have this frecvency) . I use V51.
2. For European model V20, V26. (on the battery is not written in chinese). If it used on chinese model will be no signal on Sim2 (x sign)
How to install:
Download and unzip the file modem P780.zip. Chose modem file.
1. Put the modem file (zip) on the SD
2. Use CWM, TWRP or mobileUncle
3. Install modem from recovery
4. Wipe cache
5.Reboot
Let me know if it works.

Great! Thank you.
Your zip is stored on my computer
Nothing helped, I gave all a try.
But now I found out, thats a problem if my local provider and his radio cell.
When I leave my home cell, all is fine.
I installed S920 V17 modem and both slots works for me now on my P780.
Lenovo P780 3G not working in sim1
Hi Badmania,
I also recently bought a lenovo P780. i didnt realise it was a chinese model only after going through your post. i got a little problem with this handset and i hope u can help me out with it. Slot 1 probably supports 2g/3g connection but i am not able to get 3g connection in the slot 1. i tried swiping the same sim card in another handset of different brand and i can use 3G without any problem. slot 2 works fine with 2g.i am a newbie to this android and i dont have any idea about CWM, TWRP or mobileUncle. i would appreciate and be grateful if you could post step by step procedure to change the radio module ( modem) for Lenovo P780 chinese model. i cant read Chinese and its a big problem for me. Looking forward to hear from you soon.
Regards

Confused
Dear Badmania,
Thank you so much for your help and support though i couldn't execute the solutions you have provided above properly.
Finally i realized why my 3G connection on slot 1 wasn't working after doing a vast research online. I found out that, in order to use 3G in my country(BHUTAN), i must have a smart phone that supports GSM- 850/900/1800 MHz & WCDMA 850/1900/2100 MHz Frequencies. My network service provider told me that i wont be able to use 3G without these Frequencies in BHUTAN.
As per my knowledge, Lenovo P780(chinese model) supports GSM- 900,1800,1900; UMTS-2100 only. I am worried and confused what to do now. From where and how to add GSM- 850 MHz on this handset?????
Will i be able to solve my problem with the solutions you have provided in your previous post??? OR is there a different procedure to overcome this problem. Please help me, i like this smartphone(lenovo P780) so much that i don't want to switch on to another smartphone.
Regards,
Install mobileUncle Tools from GooglePlay.
Open the program.
Under Engineer Mode\Engineer Mode (MTK)\ BandMode\ you will find Sim 1 and Sim2, where you can see what bands are availlable. GSMMode (2G) and WCDMA (3G).
This is it. You can not add other band.
As I know, the chinese model ( mine also)has only WCDMA2100 ( on mobileUncle is WCDMA-IMT-2000). I need WCDMA -GSM 900 but ...it is not possible. It is not a software but hardware issue.
There are 2 versions of P780. One with 4G storage with WCDMA 2100, and one with 8G storage with WCDMA 900&2100 .
Thank you!
Thanks a lot, Now i regret buying this phone to be used in my country!
Please help

install modem driver to P780
Hello!
I need some help. I've bought a Lenovo P780 phone and when I put in my SIM, I realized there is no signal and the phone can't connect to the network. After some advices I tried to install modem drivers. I downloaded the drivers from badmania98's upload. I copied them to the phone internal memory (tried with SD card too, with no result). I started TWPR manager (tried with mobileuncle too), pressed install, selected one of the unzipped pack, eg. v52 Modem_P780_V52.zip. Slide the slider, my phone reboot, I got the system recovery. I choose apply update from sdcard (or sdcard2 from external SD card) and choose my zip file. My output is:
-- Install /sdcard ...
Installation aborted.
Neither of zips work. What should I try? Did I miss something?
Thanks
Daniel
I need some assistance please.
Hello badmania I am in need of some assistance from you please. I bought my Lenovo P780 and as I've seen and heard, people are having bad signal quality. I was looking online trying to see if there was a way to solve this problem. I ended up on this website and saw your steps on how to do it, but honestly I have no idea what I'm doing. I was wondering if you could sort of guide me through the process please. I would really appreciate it.
Thanks,
Moises
Hey. I have the same kind of problem (chinese Lenovo P780, trying to use it in Hungary with a GSM 900 / 1800 provider) but the weird thing is that the phone loses signal occasionally. I mean if I check the phone, about 7 times of 10 there is no signal. I tried out a lot of modems (found on a russian blog) then I tried out the modems posted in here, but it's still the same. I checked the settings in engineer mode and everything is turned on. Please tell me what is going on.

Hello everyone
So I have this $200 Xiaomi Redmi Pro (MT6797) on which I was trying to unlock LTE Bands.
I hooked it up to MAUI Meta and fiddled with nvram settings, trying to stay logical where possible... that's to say I've paid attention at indices, changed at all occurrences of settings, etc (I'm a programmer after all).
Nevertheless , after the N-th dry run, I've managed to touch the "right" value and now Android says no sim inserted (baseband version unknown in system info).
More importantly, I thought I could simply revert the changes, as I have kept track of them, but MAUI Meta now balks with a big red flashing MODEM Exception message, and will not connect.
Most importantly though, I have no nvram backup.
What are my options to revive this thing?
Will it go away with a factory reset, or are nvram changes done with MAUI Meta real?
Any TWRP options? (i.e. http://forum.xda-developers.com/showthread.php?t=2594364 )
Is it feasible to just flash someone else's Redmi Pro nvram backup (...yeah I know I must change IMEI's).
thanks a lot!
I have root access to the /NVRAM folder with a lot of files named MT03_000, xxxx_000 etc.
It would be wonderful if the specific file and offsets for all settings could be extrapolated from a nvram database file...
(The settings I've changed with MAUI Meta are NVRAM_EF_EL1_ANT_PDATABASE, NVRAM_EF_EL1_BAND_INDICATOR, and NVRAM_EF_EL1_MPRADJTBL)
Why:
You imported the phone to India from another country and now VoLTE doesn't work for you. Maybe you unwittingly messed with your phones "/odm" partition.
This guide will help you get back the VoLTE functionality for INDIAN MOBILE CARRIERS*. Participate in the poll you want similar guide for other countries.
*might work for Bangladesh, Nepal etc.
Before:
Make sure your carrier supports VoLTE or VoWiFi.
Stock or stock based ROMs.
You should have at least TWRP or root.
Where:
Download the UNFLASHABLE files from here.
How:
-=:TWRP METHOD:=-
Extract the downloaded file, "volte_twrp.zip", to the root of your internal or external storage.
Internal Storage: /storage/emulated/0/TWRP (may not be the same for you)
External Storage: /storage/0000-0000/TWRP (may not be the same for you)
Reboot to recovery.
Select "Backup" from TWRP menu.
Hit "Select Storage".
Select the storage you extracted the downloaded file to.
You should see "2019-05-22-05-24-06_treble....". Select it.
You should see a single entry for "/odm" under "Select Partitions to Restore". Select it if it isn't already.
Uncheck "Enable Digest Verification..."
Swipe to restore. Restart to "System".
-=:root METHOD:=-
I haven't tried this. Let me know!
With your favorite file explorer obtain root access for "/odm".
Replace contents of "/odm" with files extracted from the downloaded file, "volte_root.zip".
Restart.
Good tutorial, but wouldn't be easier just to flash with odin the modem and csc for the specific carrier? It works even on Pie with older oreo modem/csc. You don't need root or twrp.
Tested myselsf, first Pie update was for Russia. Flashed it, but I lost wifi call and volte. So i downloaded oreo stock for my country(Romania - Orange) and flashed the modem and csc. Got back wifi call and volte.

This method only works if both the firmwares are for the same model. For examples I cannot flash Indian(SM-A750FN) firmware on a device I obtained from Malaysia(SM-A750GN) because they are different models (FN<->GN). For more information read my other guide.
Hi my phone model SM-A750FN, purchased in Europe and using in India and volte not working , only jiovoice call app working . With this app I can't access bank apps due auto verification failure ... I checked the CSC available list and I didn't found Indian CSC .... Please help me what to do
