Hey guys, I got a problem with my H850. Since I've installed the 20A modem and bootloader in my G5 in order to run Fulmics, all the wi-fi networks I connected were weak, and even when close to the router the connection level was low. Today I've installed the stock 20a rom for H850, and nothing has changed. I don't know if this was caused by the 20A modem, but I didn't notice this problem when I was using the 6.0 rom that came with the phone. Can someone please help me?

NOw my story!!
2 weaks before I brought one unlocked E970 from my friend, which runs CM11 nightly 13. The first thing I did was updating to 14 which was just released. The phone had little heating problems and gps fixing issue, also terrible battery backup due to wake locks.
So I flashed the cm 10.2 stable and found all issues fixed except the phone fails not register in 900mhz 2G networks in India (I mean weak signal in 900mhz, where other carriers like DOCOMO which works on 1800mhz are works just fine).
After reading a lot I decided to flash on nexus 4 radio (.54),but there is no hope.
Then I flash back the stock ATT_JB radio and find the network problem is resolved have all frequencies (900/1800mhz gsm) and carriers listed, but my sim is not recognizing.
Ok good, I start flashing almost every radio up there
E970,e971,e973,e977 - all gives the No sim error. ( even on LS970) ( surprisingly the all shows the same baseband also)
but all the nexus 4 radios did works, but terrible signal in GSM 900mhz. ( also experience few problems in .84 and above)
Guys I even flashed on E980 modem and find the network and SIM works amazing but no audio, speaker and demigod crash. Which can be understood since e980 is snapdragon 600 SOC.
OK I must have broke some thing lets go to the beginning, so I did the LGNPST and return my phone to 4.1.2 stock att&t.
results -- Stock rom and stock rado
problems-- not even network scan is working( error in scanning network), and of curse no SIM!!!
That's it> I rooted my phone by using freegee unlocked my boot loader and install CWM. Then flashed back the CM11 and nexus radio. Atleast the phone is working expect the volume keys are inverted.
I may have broke the EFS, but I have IMEI number and phone working in N4 modem. So the issue is with the ATT radio which may be some RIL issue I guess.
In order to get my phone useful, either I have to make the ATT radio accpet my SIM or some have edit the nexus4 radio and make it give a good signal in gsm 900mhz. Also the inverted volume keys are awkward.
To be honest I have no idea what to do next, but I strongly feels its a software error and can be fixed, BUT HOW?

you done lots of wrong things with your phone for minor network issue.
First flash Stock LGNPST to make your phone usable. And then use it for about a day. sometimes due to low signal it doesn't network.
If still doesn't work then flash EFS and Stock ATT JB modem and then try to use it.
or ask your friend if he gave you and unlocked phone or locked one or he might have bricked modem just like you are trying todo.
Flashing files for diff in your phone makes things worse and might give you Hard brick. so never flash anything of other phones. NEVER.
Your best bet is to use stock rom for a while to make things normal or else you might hard brick your phone and also if you are buying phone from someone else then first check it if everything works or not.

I did tried the stock and the modem flashes.. finally I sold it .
Anyone have the issue where the SIM card isn't recognized? I'm on the RR newest ROM and the card isn't being recognized...I'm about to try the stock ROM and see how that goes.
Similar problem
I`m in a similar position I think. However, my phone recognizes the SIM but when checking the SIM-status the mobile radio seems to be off. I can´t change preferred network type, it just jumps back to "TD-SCDMA/GSM/WCDMA/LTE , I get no results when searching for mobile networks and when I use the *#*#4636#*#* - menu the "Turn on radio"-option wont respond. I`m on latest stock firmware and the phone is still displaying IMEI-numbers. I bought my unlocked European version of Oneplus X yesterday on an auction site, the seller has good reputation and he claims that it worked fine for him. I got a new SIM-card today thinking that would have solved the problem, no luck there however. I also did a hard reset and downgraded to an earlier version of a stock firmware and the error is still there. I noticed I had TWRP v.2.8.7.0 blu_spark r5 preinstalled when I bought it, its a custom kernel right? Could something related to the kernel be the root of the problem or the baseband? Any suggestions on what to do next?
Dear community,
when I updated my dual sim phone H818p (AME region) via OTA to MM - version v20c, I realized that phone calls and SMS messaging do not work after the phone is encrypted. When trying to take or receive a call no connection is established and the phone app gets stuck. Additionally SIM2 does not connect automatically to the network anymore. Interestingly, internet via phone providers still works on both SIMs. This phenomenon is reversible, in unencrypted mode everything works flawlessly. Since I need encryption for use as company phone I have a real problem here.
I meanwhile also tried to flash the new version v20d which was recently released in Europe, but encountered the same bug with this ROM. Also resetting the phone to factory settings or flashing the ROM in refurbish mode with full memory wipe did not change a thing.
LG support (I have to use Middle East because of the phone region AME) is not very helpful. They only offer help if I send the phone in and do not comment on the issue itself.
In case anyone has similar issues with MM on the H818p (or other phones of the LG G4 family), please let me know, especially if you have found a fix to this problem.
Back to Lollipop
Since nothing worked to solve my problem with any MM version of the H818p stock software, I wnet back to Lollipop via LGUP - v10l. Very disappointing that LG apparently distributes software via OTA which has such serious flaws.
Update: I am back to Android 6 via OTA. Via another entry I learned that the bug disappears, when deactivating the SIM-lock and restarting the phone. Now phone calls and SMS work normal again also while the phone is encrypted.
Sent from my LG-H818 using XDA-Developers mobile app
Ill get right to the point, I'm on the latest FW 10e and whenever I try to enable bluetooth it clicks on and looks like its going to enable then doesnt.
The BT switch simply just turns itself off. No errors, nothing, just will not enable.
Just got my H850, booted up and on 10a FW out of the box.
First unlocked bootloader and flashed Modem/Bootloader/Boot to 10e versions and to latest Genesis rom
Still same issues.
Tried flashing back to stock 10d FW using KDZ and still having the issue.
Anyone have a fix for this or is this a HW issue?
I do not have a Sim card right now as I was waiting for AT&T to ship it..
Hi, I downloaded and installed Lineage ROM, everything was working fine but I found that I was not able to send text messages (receiving messages was okay), I tried change values under test menu (*#*#4636#*#*) but problem persist.
I tried clean installation of new ROM (Aosp).
I tried install new firmware from:
https://forum.xda-developers.com/re.../firmware-xiaomi-redmi-note-5-5-plus-t3759683
And baseband from :
https://androidfilehost.com/?fid=746163614322262750
And finally, text messages are OK, unfortunately I am not able connect to 4G/ LTE networks now. Only 2G and 3G networks are working. LTE services were working without problem on original Miui and Lineage ROM.
Can someone try help me how solve it ? I would really appreciate any ideas.
Do you think this can help?

Thanks in advance and happy weekend
i have the same question! +1
I tried fresh install original MIUI ROM, but it did not help
http://en.miui.com/getrom-340.html?m=yes&mobile=2 .
LTE is not available still.
I did not try this method still: https://androidfilebox.com/app/redmi-5-plus-modem-firmware/
But I don't have another option I guess.
With LTE no Problems = https://forum.xda-developers.com/redmi-note-5/development/rom-omnirom-t3823189
Unfortunately LTE is not working on this ROM (Omni) for me too, but I expected it, because as I wrote I tried original MIUI as well. It's problem of wrong firmware, baseband, modem or something, because hard reset or flashing new rom don't fix it. Btw, this morning I was in big city in my country and my phone was able connect to LTE, but it was 1800 or 2100 MHz, which are available only in bigger cities. When I came back to home, it showing only H+ again. It seems my phone is not able to connect only to LTE on 800 MHz (B20) currently, which is most widespread LTE frequency in my country and this one is only available one in my location. And I was able connect to this network before. Unfortunately I don't know how I can bring it back.
Solved.
My friend share her .xqcn file with me (she has same phone) so I flashed modem file via QPST Flash Tool to my device. Xiaomi started receiving LTE in my location- B20 frequency band, unfortunatelly it was continuously connecting and disconnecting between "no signal" and 4G.
The next step was flash MIUI 10 Global Beta ROM 8.8.9 to my phone via Miflash. LTE seems be stable and fully working now.
