[FIX] Possible Baseband Unknown Fix - Nexus 5 General

Possible fix for unknown baseband
Hey everyone!
So yesterday my phone was running normal and all was fine! Then out of no where it softreboots everytime it loads into android.
Logcats didn't really show anything, Dmesg did though, it was showing that my radio was crashing and then noticed the all information related to baseband imei and cell networks was unknown.
So I did some research and people were saying that the persist partition corrupts itself. No known reason as to why but I then remembered the our efs partition is related to that partition.
So after all of this I remembered I had a complete back up of the android L I have been helping with. I factory restored back to complete stock flashed twrp and copied over my twrp back up. I did this while at the beginning of the setup wizard. I then rebooted back into twrp made sure my backup was showing. I then restored only the efs partition.
I restarted the phone and BOOM it works again.
So my main point is always have a backup of everything safe and put away. and if you end up having the baseband unknown issue restoring efs will fix it
Thanks!

To be honest not much new here, backup efs once and store it somewhere, but most of the time a cache reflash/wipe solves the issue if it happened randomly.
ふかつどう

Well wiping/reflashing cache many times didn't help at all. I only posted because I have seen a lot of people with the same issue and never found a fix.

[Q] MIUI Network error, also settings are not being saved.

Hi guys,
I have just flashed MIUI and my god it looks good
I do have a few problems, I can not pick up any networks (I'm on vodafone uk). When I try to find Network Settings I get: "Call Settings Error Network or Sim card Error."
I hope it is an easy fix I have tried leaving the phone for a few minuets which hasn't helped and I have tried rebooting the phone. When I reboot the phone it goes back I think factory settings as it asks for my Google account information plus Date format.
I used the following guide to install MIUI:
http://www.theandroidsoul.com/galaxy-s-miui-rom
If you think I have a better chance to get this solved on another thread / forum section let me know and I will re-post it
Thanks.
well ideally this thread would be better off under the 'MIUI general, or the MIUI development' but considering you already posted dont worry
anyway it sounds like your IMEI is corrupted, have you checked this by dialing *#06# ??
if its all 0's or a complete different IMEI to is was before hand, just apply the efs backup you should of made before starting the flash.
Well my IMEI is fine, well it gives me a number which I think is correct But I didn't apply a efs back up not sure what that is.
If I want to reinstall MIUI would I need to flash back to 2.2 then flash to MIUI since they keep saying you need to be on 2.2 before you begin the flash.
I was on Darky's 2.2 before I flashed just fancied the change
no, you are on MIUI now right ? so just reflash the ROM again, and make sure you are on the latest kernel too.
if that dont work, try formatting cache / data / datadata / system / dalvik cache, then again, reflash the ROM
Yes I am currently on MIUI.
I used the following:
speedmod-kernel-k13c-500hz.tar
cm7-galaxys-initial-kernel.tar
galaxys-efsbackup.zip
MIUI-RC7-1.4.29.zip
Maybe some of these files conflict with the newer version of MIUI?
they shouldnt conflict.
did you try the steps in my last post ? if so how are things now ?
Cheers for your help. I flashed it back to 2.2 stock then went to MIUI seems to be working now, strange but I am happy

[Q] No more Imei, no more baseband and i can't connect to Windows anymore with USB

Hey
i think i have a bigger problem.
I had ICS Stunner 4.2 installed on my Note 7000. Sometime last night , the phone went off, and came back without recognising my SIM card anymore.
After ton's of reading , i reflashed stock gingerbread, and rooted the phone.
Still not working... So i kept on reading and thought ok, EFS problem. Lucky me, i have a few backups of my EFS (backupefs.tar.gz, efsdev-mmcblk0p1.img.gz and efs.autobackup.img)
however i did not manage to get my imei and my unknown baseband back up. I tried to restore the EFS 's i had and copied back to /efs
since nothing was working , i wanted to try EFS pro. But now, the Phone isn't even connecting to the PC anymore except in Mass Storage mode.
Is there anyone who can help me fix this ?
Thanks a lot , really appreciate any help....
Cheers
Try this man
lol, I had this same problem when I flashed new radio file thinking it would work on tmobile. Phone would not read sim card etc...
I flashed this and all was good. google this stock

Thanks for understanding and for helping to keep XDA neat and tidy!
I too had some problem with last R13 update:
- Contacts in SIM are no longer seen, so they can't be transferred to phone,
- Found WI-FI and mobile network turned off, may airplane mode have been set on by itself?
Now went back to R11
Brightness issue
Hello, loving the ROM so far!
Only thing I dont know how to solve is max brightness after I reboot the phone (I have set mine to minimum).
It gets back to minimum after the screen turns off or after I manually set it off.
I tried factory reset, didnt help.
Thanks for the help!
upgrade new rom
Hi,
last week i installed this version
20140910 Release 12 on my samsung galaxy s plus
followed all steps from the openings post of this thread:
http://forum.xda-developers.com/showthread.php?t=2579431
I used CWM.
My question is with steps should i take if i want to upgrade to
20141011 Release 13 [EOL]?
Thanks a lot
First you have to update TWRP to 2.8.0.0. from there you can flash R13 and reboot.

Installing CM11 rel11, serial disappeared - best way to restore?
Hi folks!
I've upgraded the stock firmware to CM11 rel11 from this thread on a i9001. Now it is on EOL rel13.
By the initial upgrade I assume the serial number turned unknown, so now I am only able to make emergency calls. Until now it didn't make me upset at all, however recently my priorities have changed. (In a nutshell: VOIP telephony was kicking in, thus it would be handy to turn my GPS device a 3G and callback capable... well... phone.)
Before the upgrade operation I followed the recommendation and created a backup of /efs and /persist. Not surprisingly the backed up and current images of these partitions do differ on some bits. However at this point I became a bit confused, and teh internetz didn't answer (yet?) my questions:
- Shall I simply dd the original images back, reboot, and problem is solved? Or doing so I will brick my precious device (being even unable to restore the current state of these partitions) thus lose even navigation?
- Is there any better restore tool around that supports i9001?
- Am I totally off track, and should make some other magic? (Like using some 2013 patch that kicks out S/N check, etc.)
Thank you in advance!
Project dead?
I have tried to download R13 files. All downloads hosted by devhost failed because the files seem to be unavailable. Tested with Chrome and Dolphin on i9300 and i9001.
Can you or someone who has already downloaded the files please provide an additional mirror?
And why is R13 EOL if there is no clue of a newer Version? Have you stopped the development completely or are you preparing for Lollipop?
I have the same problem as PsychoGame
"Hello ADC-Team,
First of all thank you for all your hard work on this device, it's much appreciated.
Second I want to report a small bug which I've encountered and am unable to get past. I followed the next steps in flashing:
I flashed TWRP 2.8.0.0 on my Samsung Galaxy S Plus.
Rebooted into TWRP 2.8.0.0
Completely wiped the device (Cache, Dalvik Cache, Android Secure, SD-card, System & Data)
After full wipe installed the cm-11.0-20141011-ION-dev_connection_team-release13-ariesve.zip
After flashing CM11 installed GAPPS package
Cleared Cache and Dalvik Cache once more
Rebooted and set-up device
After the device has been set-up I'm unable to use the contacts app for some reason.
I've tried clearing Cache/Dalvik Cache and Fix Permission but this error still persists
Reflashed the CM11 package again but still no luck, the error still persists.
Does anyone have a suggestion, or is anyone also facing this same problem?
Greetings PsychoGame "
I'm unable to open my contacts, i din't have the problem with release 12. Is there a know solution?
Yes I share the same problem, as said in post 21 oct 2014 at 07:30 PM.
I can't use the contacts because they can't be read in the SIM and can't be exported to the thelepone memory.
Tried with wiping, cleaning, etc., but I had to step back to a previous release (R11) very well working.
Looking at the lenght of the files I could see that R11 is 210.888 KB, R12 is 211.708, and R13 is decreased to 189.921.
Something lost

I don't share this. The contacts are properly downloaded from Google and I can access them normally. I can also add contacts and save them!
Edit: were did you save your contacts? If you've saved them on your sim card, I'd suggest an app called 'sim contacts'. I found out I had some very old contacts stored on the sim card! I almost forgot this possibility...

I reinstalled the rom and gabs again in my pc at home and the problem is gone. I have another question I like the english language on my phone because if there is a problem and a solution it is mostly written in english. I live in the Netherlands, i tried language english us but that gave problems with reception. My provider signal (t mobile) disconected sometimes ramdomly. My solution was select english united kingdom instead of Dutch and Nederland. My question about that solution is: Is it possible that i have slighter worse reception than if i select country Netherlands and language dutch of shouldn't that change make any difrent i means of reception signal strenght?
Thanks for the fast response smitharro

I don't think the language settings of your interferes with the signal of your provider. I always use English with Kpn..
Hello folks,
I still am having problems with contacts from SIM.
To make short a long story:
-1-I have my contacts (216) in SIM.
-2-I must have them in SIM because sometimes I have to put SIM in other phones neither Android nor Google.
-3-That means I do not save my contacts in Google Cloud.
-4-CM11 doesn't use SIM directly (R/W), so I used to select all contacts in SIM and transfer to Phone Memory (not in Google Cloud).
-5-I could do that until R11 and R12.
-6-(Note_1 : before an update I perform a total wipe and a factory reset)
-7-Now I installed R13 with the same procedure: factory reset and instal ZIP
-8-The transfer of contacts is not possible because contacts in SIM are no longer visible,
-9-If I install R12, copy contacts to phone, then install R13 on it without erasing nothing (cache, dalvik, reset) then i can see contacts previously transferred under R12.
Note (tried as suggested by smitharro) "sim contacts" from market. It Reads and Writes contacts on SIM, but cannot transfer to Phone, I get this message "operation failure. try again".
My question is: how can I transfer contacts from SIM to phone under R13 as per step -7- and not pass via step -9-?
I may make something wrong, but do not understand what.
Help please
Many Thanks

I tried to copy one of my old contacts from the Sim to the phone with 'Sim contacts'. It works perfect! The contact is visible in in 'contacts' after this operation! It isn't visible when it's only on the Sim card however... Sorry but I'm afraid I can't give you a solution for this, other than just use Android phones...
Hello people,
Thanks smitharro for the test you did with "sim contacts" with R13.
It doesn't work with me; if I try to copy with "sim contacts" (by Needom Studio), it gives me the message "Operation Failure" and stops.
BUT
Then I tried with "sim manager" (by Robotobia) and all was perfect: I could copy from Sim to Phone and from Phone to Sim.
(Info: my sim operator is WIND, memory capacity 64 KB)
I hope this could be useful for other people that might have same problems.

Glad it finally worked out for you! I used the Needom Studio app. That one worked fine for me. Don't know why it didn't work for you. Most important: your problem is (somewhat) solved, although it's just a workaround. The Rom still doesn't read the sim-contacts 'by itself'. For me, personally, that's not an issue. Hope the rom will be made 'perfect' before it reaches it's real EOL... On the other hand, nothing in life is absolutely perfect! remember: this rom is brought to us absolutely with no charge by people who volunteer to do this development, just because they like doing this.
Still confused
Hi again
I'm still confused, whether it is safe to dd my saved partitions back to restore my serial number. (Still not 100% sure if these partitions are bound to a particular firmware revision, e.g. only usable as a source to harverst my serial from, not to restore anything; and neither 100% sure if dd is the best tool to rewrite them.)
Having no - even a short - answer means I am asking something pretty obvious? By my opinion if it were obvious, google had answered it already - but it didn't.
Any answers appreciated.

First of all, your question is not fully clear to me. What doe you mean by serial number? You're IMEI number? If you've lost that, your phone is nothing more than a small tablet. This is a unique number to identify your phone on the provider's network. So you'll have to restore the backup!
The serial number in my phone however is 'unknown' in the rom. But the rom works fine! There's no need to have that for the use of this phone. I don't know where it was stored in the original rom, but be very careful with messing with the 'EFS' partition!
Thank you for your reply!
My IMEI number remained well, however I learned that both IMEI and serial (S/N) is needed to have a phone (e.g. to connect to carrier) instead of having a tablet.
For example here is said: "IMEI is showing now but still no calls and sms. I also noticed that the serial number is not the same as the one written at the back of the phone. I have read that restoring EFS solves this problem".
There is also some magic ("azira patch") to S3 that states the same. It operates by bypassing serial check, but since it is old (2013) and originally for S3, I'd rather stuck restoring my /efs partition.
Backing up /efs is written down everywhere. Restoring it... well. Mostly external tools are mentioned, that don't support i9001.
Even further, suppose restoring /efs and /persist is the solution for my problem, I think I know how to do that. At least by dd. What I don't know is that the structure of these partitions is fix or may change between Android versions. And of course: if I rewrite them to original, will my device boot again?
Considering these, any idea if I'm off track, or not?

I never touched my /efs partition nor will I ever! My phone is running fine without the serial number displaying in the rom! I can make phone calls, send text messages and I have mobile data! So you really don't have to restore the serial number. Possibly it's still there and still used by the provider, but is the settings app simply not reading it... Sorry I can't help you more. I'm not a developer, just a user...

Baseband Unknown & IMEI null (SM-G900A) - Please Help

The story
Hi everyone, thanks for reading me and thanks for your time.
I am stuck with this galaxy S5.
I got a S5 in the past, a beautiful SM-G900F on which I run lineageOS no problem whatsoever.
I bought another S5 from ebay, turns on it's a G900A.
Had problems from the start, the phone seemed to often restart instead of turning off normally, and I had severe battery drain both while on and while turned off. So I went to this section and looked at Root, Roms and other cool stuff and followed the guide to put up a custom ROM.
The problem
The first step, installing the experimental firmware, seemed to work but after reboot no OS would install, instead I got "MODEM CRASH".
So from there, I tried to roll back to stock.
I put on BOF3, which works, but since then I have baseband null and IMEI unknown.
Panicking, I tried to install COI5, but same problem there and also multiple bugs, so I went back to BOF3 and it's all functional, but same baseband/IMEI problem.
I have tried to reset to the oldest stock G900AUCU1ANCE but ODIN fails at the very start. I seem to understand I'm on android 5 and cannot rollback now, somehow.
If anyone has any idea on what I can do realistically.
I have no EFS backup as when I started I didn't know what EFS was.
Thank you all for your help.
I have seen many topics with this problem but I have only been confused more by them so forgive me for posting here.
Bump!
Can anyone help?

[SOLVED] Wi-Fi MAC address 02:00:00:00:00 after restoring stock via fastboot

I had this issue after I downloaded and flashed the most recent factory image for my Moto G5S Plus (XT1806) from this post: https://forum.xda-developers.com/showpost.php?p=76070231&postcount=24. At the time, it was NPSS26.116-48-12, build date March 1st.
The restore succeeded after following these instructions, except after the restore, my Wi-Fi was broken. Mobile data and other connections worked (not sure about Bluetooth), and the Wi-Fi MAC address was shown as 02:00:00:00:00. I tried re-flashing the modem and fsg partitions and erasing the modemst1 and modemst2 partitions, but it didn't fix my issue. Reflashing everything from scratch using the same image also did not help.
I was only able to solve the problem by flashing an older image entirely from scratch, specifically NPSS26.116-48-9 with a build date of January 11th. After that, the system showed the correct Wi-Fi MAC address and prompted for an update to the latest OTA release after setup.
I hope this helps someone avoid the panic and troubleshooting I went through.
Edit: Basically just putting this here because past me panicked and ended up following his own guide to fix a separate but related problem. Future me can sometimes be an idiot but I'll be him someday so I really shouldn't talk **** about him. Future me would be really angry at current me if I didn't at least write down the steps past me took to fix my latest problem.
The issue: OTA updates were failing because my /system partition had been mounted read/write in TWRP before taking the backup. As a result, no updates would install.
Solution: Go through the instructions linked in the above topic, ignoring any Preflash validation failed errors while flashing gpt.bin. At this point, the phone boots up clean but with no IMEI. Check for and accept every OTA update available. Once updated to Oreo, IMEI reappears.
Hey buddy, i'm facing the same problem. i was able to restore my mac address but after a while phone reboots and the mac address again resets to 02:00:00:00:00
I followed every step mentioned in the post correctly and also tried custom rom's but still no permanent solution.
any help would be appreciated.
Thank you
