[Q] Radio flashes to fix signal loss not working

Hi, I'm not sure if theres thread on this but my signal is lost. two weeks ago i wake up one morning to find my service isnt working,the sim does work on my two old phones so it's not a sim issue. I then found my baseband is unknown. So I searched and found some fixes which are too flash the radio with a new radio through either clockwork mode or nexus toolkit. I've tried 5 different radios all being diffrent updates of the galaxy nexus radio. I was runnung 4.2.1(which i hated) but now I got android revolution HD 2.1.2 and ak kernel and downgraded to 4.0.2(yes the phone is unlocked and rooted). I was wondering can anyone tell me whats wrong before I factory lock it and unroot and send it in for warranty repair. Btw phone was with Rogers/Fido carrier.

Since you've done all that, we don't know what's wrong with it. 4.0.2? You're missing out on security fixes (been talked about a lot lately), new features, optimizations, not sure why you're running it. That aside, and I'm not saying it will do anything for you, you could try GetRil from the Play Store, to see what RIL you have installed, and if it recognizes any baseband at all. Your radio (or radios, we don't even know which variant you have) may be dead, who knows? What's the latest baseband you flashed? What's the latest bootloader you flashed?

Any luck in fixing this problem? I'm having the same issue after trying to install Update v5 with Knock On. I tried installing the basebands but most of them will give Service Disabled with Unknown IMEI. But the E988_HK_Final baseband shows the IMEI and Phone Number but has No Service though or very weak signal. Also, it seems like the QRemote also stops working in my case.

Please flash LG F240L Rom (KDZ File), It will work,

It looks like your EFS partition is corrupted. Did you back it up through Freegee before installing the custom ROM?

I had this happen to me with an e980 out of the box. I ordered it online, and was in the process of adding my apps and customization without ever rooting it or doing anything outside of warranty and all of a sudden I got "Insert a valid sim card". Just happened out of the blue and I only had that phone for 12 hours. It is some rare hardware issue that AT&T couldn't figure out either. I believe it is the sim slot that is malfunctioning because in mine it wouldn't recognize any sim card but my sim cards worked in other phones.
If you have a contract phone, undo root, flash the stock rom, factory reset and call tech support. They replaced mine for free because it was determined to be a hardware issue. Good luck.:silly:

[Q] N7100 No Wifi after "Emergency Calls" FIX and WiFi Fix (STOCK 4.3)

Hello Everybody,
I would like to begin by saying how much I've learned in xda-devs in the last few days just by searching around the forum and Fixing different things here and there.
This is such a great community that I decided to register
OK so heres the deal:
Last week i bought a Note-2 (N7100) running Samsung Android 4.1.2 (Israel Version) + Rooted
I wanted to upgrade to 4.3 but 4.3 isn't yet released in Israel according to sammobile.com and other people I asked.
I found a Stock Deodexed Pre-Rooted ROM here on the forums (I think version was MK4), Flashed it, and lost cellular abilities (there is signal but emergency calls only) and WiFi.
Flashed WiFi FIX by Dr. Ketan, and by installing Devil's kernel (Patched_N7100_MK4_KERNEL.zip) and GT-N7100_ModemMJ9.zip I was able to gain 3G Functionality back.
Phone was working great for a few days, but then I decided to upgrade to Dito Note v3.2 because i wanted Note-3 Functionality.
After flashing it, I lost the ability to register to network again, started receiving "UIds on the system are inconsistent " and phone crashed every few minutes, screen stoped working every now and then.
I immediately looked for a different ROM to flash, (couldn't find the original ROM I flashed but i found DrKetan_Custom_ROM_V6_1).
So i wipe the phone, cache, sd-card and everything besides formatting the internal storage, Installed this ROM but still had the same issues with ULDS on the system, phone crashes and display shuts down while phone is still working).
Desperate, I downloaded Stock firmware (With KNOX) and flashed it to my device (I used Odin 3.09 and flashed everything, BL,CP,AP,CSC that was included within the original ROM). this was the Seri-Lanka firmware if I remember right.
This time phone boots without complaining about system files, but got "Emergency calls only" (IMEI and S/N still ok!).
In addition, I now have bootloader with KNOX.
I then thought, maybe the modem version is incompatible with the Cellular frequencies in my country (Israel Freqs: 850,2100), so i looked for countries with similar freq and downloaded official firmware for Thailand.
Flashed it with ODIN (same as before, BL,CP,AP,CSC basically everything) device boots fine, WiFi was working, but couldn't register on network ("emergency calls only") even if you can see your provider while manual scanning, registers successfuly apparently,but still no service.
Fraustrated, I rooted the device (Knox turned 0x1 but it doesn't really matter to me cause no warranty anyway), installed Philiz and flashed the 2 Fixes I mentioned at the begining (Devils kernel + Mj9 modem).
This resolved "Emergency calls only" issue, but now i cannot open WiFi at all!.
I tried to flash WiFi fix that i found in this forums but it didn't work. I've given everything I have in the last 2 days trying to fix this issue but I cant seem to solve this problem.
Now I'm just thankful that I can start/receive phone calls with my device.
I can't seem to understand, how did I not have signal with stock ROM?
could it be EFS was corrupted somehow so that only MJ9 Modem + Devil's Kernel read it?
How can i FIX WiFi?
Included screen-shots of "About Phone" and "*#1234#"
Thanks ahead,

Just flashed this with Odin 3.09 but it didn't solve Wi-Fi Issues. isn't this fix for devices without the original Bootloader?

OK Thanks very much for all of your help.
Does it matter what version of 4.3 I choose to flash via Kies?
In Israel only version 4.1.2 is available and I know that going back from 4.3 most likely will erase my IMEI / S/N.
If i choose a stock rom from SamMobile does it matter what country it comes from?
I don't really understand why are there different modems to different countries, aren't all versions alike?

i have the same problem, and like you, i tried all fixes, but, with nothing solution. I've been thinking that there is no solution, just sell the bad phone and buy a new one, and then no more experience with :crying:

I don't belive in this approach, I know for sure that there is a way.
after re-flashing with Kies and getting "Emergency Calls" again, i tried to flash only the modem, and i saw that i lost connection with cellular but Wi-Fi was still working. only after flashing Devil's kernel it seems that Wi-Fi stops working..
I just got home and i'm not expecting any calls until tomorrow, I will look around maybe an alternative kernel will solve our problems..

Maybe we just need the correct kernel and modem, the problem is that no one's development. Another solution would be to discover how to downgrade from 4.3 to 4.1. For now, our only option is to wait for more solutions and development

OK, so as I promised yesterday, I had the time to dig in to this subject yesterday and I managed to find a solution to get both, WiFi and Cellular working (together!)
Here are the steps i took:
1) Installed Stock ROM 4.3 with MK4 as the main and BL version (this will install Knox but i already had it) and modem version MJ9 (Odin 3.09)
2) Root the device with CF-Auto-Root-t03g-t03gxx-gtn7100
3) Install custom Recovery (I used philz_touch_6.07.9-n7100.tar.md5)
4) Very important! After device boots it automatically attempts to perform update with samsung! DO NOT LET IT as it will install updated modem version. it is important that we have MK4 Kernel and MJ9 Modem for this to work.
5) Flash via recovery the following files:
a) Patched_N7100_MK4_KERNEL - This installs a patched Kernel only this time because we didn't let phone update version after boot, it will be compatible with Phones version.
b) GT-N7100_ModemMJ9 - This patches the MJ9 Modem.
After performing all the above steps I finally managed to get Cellular connectivity and WiFi together. Hope it works for other people as well.
I still don't understand why Stock Kernel with Stock MJ9 modem won't work, what do those patches contain that allows me to get connectivity to cellular network?
This device is not black-list and IMEI is still original and S/N but for some reason won't work with stock.
Seems to me like some of the ROMs maybe modify EFS so that only patched Kernel and MJ9 Modem will work and it's not backwards compatible.
Can anyone confirm this? and if so, is there a way to convert the "modified" EFS version to stock compatible version? or is the EFS file encrypted with propriety Samsung encryption?
You can download the referred files here

Hi, as you can see modem version for you is ending with MJ4 so it's not the same as my version.
Look for a version that has modem version ending with MJ9 and then apply the patch (because patch is for MJ9 modem, and not any other modem from my understanding)
Hope you get your device working!!

More explanation
Here are the steps i took:
1) Installed Stock ROM 4.3 with MK4 as the main and BL version (this will install Knox but i already had it) and modem version MJ9 (Odin 3.09)
2) Root the device with CF-Auto-Root-t03g-t03gxx-gtn7100
3) Install custom Recovery (I used philz_touch_6.07.9-n7100.tar.md5)
4) Very important! After device boots it automatically attempts to perform update with samsung! DO NOT LET IT as it will install updated modem version. it is important that we have MK4 Kernel and MJ9 Modem for this to work.

b) GT-N7100_ModemMJ9 - This patches the MJ9 Modem.
Hi there, and thanks a lot for your effort, I am really confused about step number 4, I haven't detected any update from Samsung's side, can you please provide more explanation?
Thanks

G3 D855 No cellular connectivity since upgrade

Hi, my eBay UK purchased reconditioned D855 did an LG software update last night for "Google optimisations" and it installed, I believe, the v20i-aug-26-2015 update.
My phone says it's now running V20n-TUR-XX.
Hardware info
Model: LG-D855TR
Android version: 5.0
Baseband: MPSS.DI.2.0.1.c1.13.2-00002-M8974AAAAANPZM-1
Kernel 3.4.0
Build number LRX21R.A1445947622
Software version V20n-TUR-XX
Network: Three
Everything worked perfectly before the LG update, now it can't see to any cellular data network (I have the signal strength meter showing but no data icons at all) and it was working perfectly before the update.
It works fine on wifi.
I've factory reset and checked everything I could - it's still not seeing the cellular data network. I've manually selected three and let it do it automatically but still no joy. Data is enabled.
LG can't find the IMEI on their system which means it's a foreign or international version I guess and, despite the fact I'm 99.9% sure their update has screwed my phone, they won't take it back to fix it.
What are my options do you think, re-flashing? If I have to then I'd rather go to a stock LG rom or, if possible, a vanilla Android ROM. What do you think, and what flash options do you think I should go for if I have to flash? Fairly n00b when it comes to doing that.
Thanks for any help you can offer!

Solved, but don't know how to delete.

As long as you didn't flash pie and lose your baseband that way, you can fix it.
If you're on stock just go to recovery and do a factory reset from there, it should bring your baseband back. However, if you've flashed a modem from a firmware not intended for your phone, then you need to reflash the correct firmware then recovery, factory reset. If you flashed pie not intended for your phone, you might be out of luck depending on what variant you have.

Stick to one thread or create your own, posting the same problem in 20 different threads won't help you in any way.
