[Q] MIUI Network error, also settings are not being saved. - Galaxy S I9000 Q&A, Help & Troubleshooting

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] [MIUI ROM]Problems and Troubleshooting

I just performed a fresh installation of the MIUI RC5 on my i9000 and Have a few problems.
1. My network provider is not being recognized at all. (Even after a couple of restarts)
2. My IMEI is not being displayed. (Even after deleting the efs folder using Root Explorer.)
So please respond immediately as I wish to continue using this ROM.
Thanks in advance
you have to restore the efs backup that you should of made before the installation.
that will restore the IMEI and give you network coverage.
if you cant do that, re-flash the ROM, and if it still doesnt work, you will have to flash back to froyo with pit and repartition and start the whole process again.
Thx a lot dude. Trying it right now. Hope it works *fingers crossed* http://media.xda-developers.com/images/icons/icon11.gif
I tried to install MIUI through Rom manager and now the phone just flashes SAMSUNG but never boots up. I have Infuse-rooted-CWM installed. Please HELP
Thanks

WIFI Sleep policy does not seem to work. It is set to sleep when screen is turn off, but it never turn off. This is draining up the phone battery. Any one any idea?

So you have the Samsung Infuse? Because this is the Galaxy S forums and I don't think Miui is even available on the Infuse so no wonder it isn't working(and the way you installed it isn't the correct procedure anyway). You can probably install a fresh official rom for your phone some how through odin but I'm not familiar with the Infuse. Best to go to the Infuse forums and ask. Hope this helps

[Q] Identify my previous official ROM

Hi guys,
I'm sorry for my english...
I had a galaxy S i 9000 with froyo (I suppose).
I was trying tu update my phone with cyanogen or miui but now the phone is always on "NO SERVICE"...there's always no signal and I can't call or send sms or connect to internet by 3g.
I've tried
miui rom stable
miui rom developer
cyanogen nightly
cyanogen stable
but "NO SERVICE" is still here!
Now I'm trying to get back to my previous rom, the problem is that the only information that I have is this screenshot (I can't post it because I'm a new user...) that says "Versione firmware corrente: PDA:JM2 / PHONE:JM1 / CSC:JM2 (TMN)"
I suppose it's froyo but I'm not sure...
Searching with google seems that my galaxy is a portughese version!
Can anyone help me please?
Thanks a lot!
Same thing happened to me, try this for me:
Go into Settings -> About Phone -> Baseband Version
What does it say? I previously had this problem a few times because somehow my Baseband would get screwed up mostly from improper flashing.
I can suggest you flash one of the JVT stock roms and it should come back. That usually fixes it for me.
http://forum.xda-developers.com/showthread.php?t=1289875
Try this one and flash it via odin.
Well on baseband says I9000XXJVO...
Now I'm downloading the ROM you've linked, I hope to resolve!
Thank you!
Hmmm okay, well try and see if it works, hopefully it does
Doesn't work with the ROM you've linked...
I can't understand how to get out from this problem!
Bohoooooo!
Well no way to get out from this problem...
Now I will try every ROM I'm able to find... Am I right?

I have had this issue a few times coming from Stock roms to CM based roms such as MIUI and Cyanogenmod.
the solution i have found is to:
Install Stock and a decent Kernel.
wipe Data/Factory reset
Wipe Cache
Wipe Dalvik
install CM/MIUI
if still no signal/ and no IMEI shows in your phone settings try flashing a modem from CWM.
you can find a list of flashable Modems here:
http://forum.xda-developers.com/showthread.php?t=1158783
Question?
Do you get "no Signal" when you flash a stock rom (Such as JVT)
STOCK Rom Link: http://forum.xda-developers.com/showthread.php?t=1289875
if you dont get any signal with stock, have you tried flashing an earlier stock rom with an earlier modem?
sammobile.com has an extensive list of stock roms.
from what i can see there is a JM5 rom on there which may be the closest your going to get to your "Phone:JM5" modem.
hope that helps.
I solved the problem flashing a modem!
Thanks so much Danh2009!!!
Thank you everybody!

[Q] Problem with Slim ICS 3.5

Hi guys,
i have been using Krarvind's Slim ICS 3.5 for about 10 days and I absolutely loved it. I have just updated to 3.6 which caused my phone to bootloop
So, after an hour or so of labouring and trying to work my way back in to it i'm now back on 3.5, but I have absolutely no signal/3G coverage. Wi-Fi works no problems, just no signal!
I went in to the APNs and there is nothing there - I tried to save a new APN and it wont let me - has anyone encountered this before?
Thanks in advance
Haven't experienced this myself but a few things come to mind...
First would be to check if you imei number correct? If not you would need to restore this from a backup.
If IMEI number appears correct then I would try flashing the modem again or a different modem. Modems found here: http://forum.xda-developers.com/showthread.php?t=1158783
If this doesn't work you can try flashing 3.5 base and essentials again.
If that doesn't work search the threads and google or hope someone else can give you an answer. If you don't find any help then as a last resort you can flash a stock rom with Odin although I'm sure there must be an easier way.

I've had a similar problem, the updating to 3.6 just went wrong. No bootloop but loads of FC.
My solution has been going back to recovery, do a full wipe (wipe data/restore factory settings) and install 3.6 again. Everything seems to work now but I have to re-install and configure all my apps... :-(
Hope it helps...
Check in About > Phone
Under baseband does it say UNKNOWN ?
this happened to me once, need to reflash the modem. No need for wipes etc

[Q] Problem LTE Galaxy S3 Wifi and Mobile Internet

Hello everyone,
As the title says I have a problem on my S3 (i9305).
First of all I want to know that it has been dropped or anything,
I put the official version 4.1.2 (the DBT for Germany was the latest then) instead of 4.0.4, rooted + busybox + modem network Vodafone Romania (XXBLL5) and it worked just fine until yesterday.
I arrived at work I checked my mail via wifi network, I disconnected I put on charger and after an hour I removed to make some mail and then give it to initialize wifi stupor show he wants to start and stop and did not want in any way to start a (looks like starts and stops).
Good now seeing that I got it and I somewhat empirically and did the following things:
-clear cache, wipe Dalvik, reset permisions - still did not work
-restore the Nandroid for wifi - did not work
I managed to got mad and threw factory reset - still not working height
-continuing with nervousness I flashed phone about 4 times with different versions 4.1.2 and version 4.3 but bootloader of 4.1.2-
Normally he did not want none and some gave the "camera failed" error.
All versions have been flashed after wipe cache, dalvik and factory reset so I say something to remain excluded from one another.
Now I'm on a Vodafone version 4.1.2 on sammobile after I haunted a bit on the internet I saw that its more people with this problem and someone had an alternative after you rename the file "wpa_suplicant.conf" in root / data / misc / wifi.
I did this and go but it is something temporary peak for once stop or restart your wifi is not working and another thing
mobile internet does not work without you come in APN and reset its there.
Sorry I did read both but I do not understand the phenomenon and to solve it because there can not be a hardware problem but rather a problem or write permission on the root folder.
And now comes the question: is there a solution to my problem or a way to see if some parts are protected to rewrite or corrupt?
Sorry for my english i use google translate.

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!

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

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...
