Hello everyone.
My problem is simple, I can't change the modem.
More information:
I got my P780 some time ago with 4.2 from the vendor. For some days now, the device was softbrick'd. After a complete flash and 3 days of back and forth I got 4.4.2 S221 Life installed with TWRP and CWM recovery (can easily change between). With this version i actually CAN (miracly!) connect not only to 3G, but to 2G!! (Only version so far for me)
If it helps, I live in Germany and probably got the chinese version (chinese letters written on battery)
Problem is, the connection is not very stable :/
So I decided to switch the modem to v51. That's where the problems start. I got the zip on the ext_SD, flashed with TWRP and CWM and wiped the cache. But the "Baseband version" is still at "P780.V101..........", even after several modems, it does nothing!
My second problem is, that the WLAN-connection only works once. I enter the password, it works and after I got out of range and back in it won't connect again!! I have to "Forget" the connection and connect all over again with entering the password.
I really hope you can help me

what i found is Alice Project Rom gives you the best wifi signal and somewhere in stympy s post you will find attached modem .. now that you are in germany i think it will work best for signal... just flash it from recovery

Thanks for the quick reply.
Unfortunatly this doesn't help either. I flashed it, but the signal strength is nevertheless bouncing between nothing (maybe 10db above noise) and full reception. Also in 2G as well as in 3G.
AND the Baseband version haven't changed at all (still v101)
what i noticed is with Alice Project i got the best signal reception for WIFI and for phone also ... its using baseband of S920.V101 may be thats why...
or alternatively serach for S920 modem drivers and give a try ..
cheers

I tried nearly every modem I could find (around 15-20) but none changed the baseband version or anything.
Thats my problem

Hello guys,
I have a severe problem with my SGS2.
I was using it as always when suddenly my signal strenght dropped down to 1 bar and since then it's changing between 1 bar and "no service".
I have been running on CM10 Nightly 20120910, thus I thought I'd try another modem. Flashed XXLQ6, nothing changed.
Then I flashed the 20120908 nightly - no change
flashed CM9.1 with XXLX/XXLW modem - no change
reflashed CWM Kernel - no change
I tried using another Sim-Card which operates in another network - no change, still only 4% signal strenght (looked up using Network Signal Info)
The I tried using my current Sim-Card in another mobile phone, and there it worked flawlessly.
WLAN is still working, but no GSM/UMTS. Even if I have 2 connection bars for some seconds, I still have no internet connection via UMTS during that time.
Anybody got an idea?

I'm facing the same issue. Did you solve it?
If it happened suddenly and the problem persists in other phones, than it's your network operator cell.

The problem doesn't persist in other phone. I've tried the SIM in two other phones and it works perfectly.
Also tried another SIM(which works on some other phone) but don't work on mine.

Hi!
Since you are new here, it may be the best time for you to read the forum rules not that you've done something wrong but just to inform you about it
Here's the list of modem that you can flash http://forum.xda-developers.com/showthread.php?t=1131950, it comes along with a guide..
Since everything you mentioned failed, i suggest you flash back to stock firmware and do a factory reset it might just do the job..
i hope this helped you, cheers!

Upon your insistence, I flashed the official stock again, did a factory reset. Still facing the issue. Flashed two different modems again. Still no luck.
Restored by original EFS, no luck. Fixed RW of EFS folder. No luck. Still the same issue.

Sorry I didn't read
If you've already full wipe'd your phone and then installed a stock firmware and the issue doesn't solve yet, it may be a hardware-related problem, also because you said that another SIM, working on other phones, doesn't work on your S2.
Try another full wipe and install a different firmware, and if still not, I don't know...

as subject last few weeks ago I've got this issue, previous months it was working fine.
when my mobile data ON (SIM1), GPS auto ON, tried many times to turn it OFF it keeps back to ON after few minutes.
It's annoying since its drain my battery. Suspect it is related to google location sharing, so I turn it off all location sharing then its back to on again and again. But it is no issue when I turn off mobile data at SIM1 (3G) and connect via wifi also no same symptom when I moved simcard to SIM2 (2G) and using mobile data.
So, first what I did is do factory reset and do ROM refresh trough maintenance mode -- > no luck
downgrade ROM from 124 > 119, factory reset, formating internal and external storage, and do ROM refresh trough maintenance mode --> no luck either.
at this point im hopeless and thinking to move to previous brand which is run more stable. So, any guide or help it will be very welcome before I throw this lenovo :crying:
thanks.

I have a question. Did you try to change your SIM card with a new one or to change your GSM network something like Orange with Vodafone?
Sent from my Lenovo P780 using LiFe v.07 and TWRP 2.6.3.0.
Hi,
I too experienced the same GPS auto on problem. It all started about 2 weeks ago and sucked the battery a lot.
I tried to downgrade my ROW 8GB S124 to S119 original rom, same problem persist, then I tried S123 rom same thing, and now I am back to S124 rom nothing solved. I did wipe the cache, Dalvik, data and andriod secure during each upgrade / downgrade, and also format storage and reset from Android system. Also tried custom rom, not successful in solving the gps problem.
Really haedache with this problem, does it mean that my phone has hardware problem ? Or I have to change another sim card into slot 1 to see if it reproduce the same issue ?
GPS Auto on problem
Hi - I have the same problem. I 'm using Lenovo P780_ROW_S116_130828 ROM. I've noticed that the problem appears only on local roaming. My network enables local roaming on T-mobile. Only then it switches on GPS. As if it was launched by the APN? I've tried to switch off all services with location/fused location/geotagging etc. no luck. Problem disappeared only when it is unable to dial (to many services switched off). If it dials thru t-mobile - GPS launches. On standard network - or other providers everything is ok. Changing modem img to v52 - also no luck. What I know is that whenever I turn off Allow Network Initiated Request in Mobile Uncle Tools (AGPS settings in dev mode) it reappears switched on. Maybe it is the problem?
So... I have been using my P780 with the S136_ROW ROM for almost a year now without much hassle. Then I decided it would be nice to upgrade to KK, which did not go well (see posts here if interested). I went back to my original S136, but then my SIM's started to have massive connection problems. One SIM sometimes connects, the other, a twin bill SIM (2 numbers / accounts on one SIM, 2 five-digit PIN's), does not connect anymore at all (PIN's get checked, but SIM's do not connect to networks).
Both SIM's did fine before on this phone, and they still work fine on other phones. Other SIM's (non-twin bill) have the same issues on my P780 as my own SIM's. I tried to install a few other ROMS with varying, but always unsatisfying, outcome.
I'd be grateful for any ideas - thanks

You probably need to search a better device. I have a similar problem with my P714, and it gets worse every day - it began the way you describe, and after a while, restarting (or using apps that do it, which is basically the same) stopped helping. I'm about to get rid of this device as it doesn't supply the most basic functionality. BTW I replaced 3 ROMs since this problem began without luck.

It can be rom related but if you don't flash with kdz zip flashes will usually flash just kern and rom. Want me to cook a flashable zip with modem? Tell me if you run kitkat or jellybean.

Good day guys.
I have a problem that I think is very common, however I haven't found a solution yet. I recently update my S6 edge (925I - latam) via odin to Nougat, everything was cool but I can't do or receive both calls or sms. I have cellular signal, however there is not registered with the network carrier.
I already flash modem.bin from older firmwares and do not work. Sometimes I loose cellular connection or stay the same, with signal but not registered. I tried other possible solutions like airplane mode and reboot, flashing roms, connect only via 2G or 3G, nothing have worked. My sim is not corrupted and the imei is just fine, without report or related.
I hope you can help me. Thank you very much.

Same issue for me.
Tried:
OTA update
Odin update - installing new stock firmware (with different software version)
Factory reset
Installing TWRP + LinageOS beta
Replacing the sim slot in a service
Nothing worked. Anybody?
Look in settings > status
Do you guys have an IMEI?
This happend to me 2-3 times last 30 days... sometimes I have signal but not registred on network, sometimes there's even no signal, etc...
I also tried several things to resolve the problem...flashing modem, reset dialer, changing network mode, enabling airpalne mode, another SIM card, etc... For the 1st time, flashing modem helped... but 2 days ago when this happened again flashing modem did not help...then I tried changing network mode and I got signal again... last night it also lost signal and today I changed network mode to 4g/3g/2g auto and it got signal again, then switched back to 2g and it's fine till now...
Hope this will not repeat....if does, coulb be very annoying thing...

Bro, download some older firmware from the one you have from sammobile and exctract it...there you'll find modem.bin
At last, I couldn't fix my s6...so I sold it...then the guy who bought it needed to write some chip to motherboard and he got it working again...
