[Q] Limited Service

Hi,
Now I'm S-OFF and rooted.
However I'm still having problems with signal reception on the wildfire s
Doesnt seem to work well in weak signal areas. Not half as well as my x10 mini pro.
The o2 sim definitely works in the phone as I've used it this week at home just at work its
Any suggestions settings etc I can change?
Data connection seems to work everywhere just phone signa

after messing around with the phone a bit I've found I cant connect to GSM networks using my o2 SIM.
This is after using the XTC clip and flashing an unbranded ROM
I've got a feeling this has something to do with a failed unlock attempt while it was on T-Mobile.
Something wrong

dunno if this may help but try to change the preferred network type from the *#*#4636#*#* hidden menu

Might sound a bit simple but have you tried wiping the contacts on the sim with a cloth?
I used to work for O2 technical and this seemed to fix a lot of seemingly network related issues.

I had o2 send me out a new sim last week so its not the sim.
The phone performs great where I live which has a really strong HSDPA signal.
The odd thing is my old x10 mini pro never had these problems.
from the test menu(*#*#4636#*#*) if I select GSM only I get no connection at all.
Its like it wont connect at lower speed.
it seems a bit like this problem http://forum.xda-developers.com/showthread.php?t=805024

Sometimes all my signal drops while my mums x10 mini pro which is also on o2 has full signal. After a few mins it comes back, but sometimes I get full signal and then other times I get about 2 bars. Pretty strange.

No idea..i have some network problems too but mainly in places where signal is usually bad.. i had the same problem with my nokia in same place before.

I'm going to try doing some experiments today with other peoples SIM cards see if its a phone issue or a network issue.
I'll be gutted if its the phone after waiting so long for S-OFF. Really like the form factor of the handset its perfect.

Baseband
47.10.35.3029H_7.46.35.08
Build
1.33.401.2 CL44680 release-keys
If anyone else is on o2 and not having signal problems can you let me know your baseband and build numbers. I'll try changing ROMS

Update
I've tried the following SIMs with the following results
o2 = no signal (data OK)
Orange = no signal (data OK)
Vodafone = no Signal (data OK)
T-Mobile = fine 3g and HSDPA
These are SIM cards from people in my office that get full beam on their phones.
I think my phone is still somehow locked to T-Mobile kind of partially unlocked somehow.
WTF! thought that XTC Clip was meant to factory unlock it

I don't think it'll be locked still as you wouldn't get any signal on anything other than tmo.
I'm no expert but it does sound like an issue with the rom.
Have you tried wipe - re-flash - wipe?

I've used RUU roms and wildspirit. They had the same issue.
Could I flash a rom from the bootloader by renaming it on the SD?

(again, no expert) I don't think you can flash custom roms from recovery using stock recovery.
You can flash stock roms though

renamed a rom to PG76IMG.zip and copied it to my sim
in bootloader you get a bit more info.
I'm wondering what the radio versions are in the pics below
[8] RADIO_V2
[9] RADIO_CUST
after the first bit was done it rebooted and came back and did the second
[7] RADIO_CUST

I think the radio v2 relates to the radio file in the rom and the radio cust to rcdata?
I've just opened the rcdata in the stock rom with a hex editor and it contains:
QCT_UMTS_RADIO_VER=1.DisH=1.HSDPACat=8.QCT_UMTS_RADIO_END=1.
Don't know if that relates to anything...
How's it going so far?

Flashed the stock HTC through the bootloader with the same results
I'm definitely unlocked as this abd command shows I have supercid
D:\android-sdk-windows\tools>adb shell
$ getprop ro.cid
getprop ro.cid
11111111
I've got a feeling that t-mobile use a custom radio which is buried somewhere in the phone which overrides the stock radio.
Just wondering if there is a way to include a custom radio img file in the PG76IMG.zip which would be flashed over the tmobile one.

My signal seems to always drop when I put my phone on my laptop when I'm using it. Once I move it away the signal comes back.

Here are a couple of zipped logcat extracts for radio
radio_output1-o2-WCDMA.txt
radio_output2-o2-GSM.txt
One when I was connected to o2 with WCDMA preferred selected in settings. The second is where I changed settings to GSM only where you will see connection drop.
+CME ERROR: 30 at the end refers to CME ERROR: 30 No network service found that out here http://www.smssolutions.net/tutorials/gsm/gsmerrorcodes/
If anyone wants to play grab the android sdk or just get adb from somewhere and run the following with usb debugging enabled
adb logcat -b radio>outputfile.txt

[Q] No signal after flashing Miui

Hi Guys, I am having a weird problem that needs your help. I have been using my unlocked Nitro HD (P930) with the official stable CM9 rom. After hearing all the goods of miui, i gave it a try (with full wipe, data/factory reset, cache partition, and Dalvik Cache). After flashing it, the first thing that poped out said the network is locked and the page for sim unlock was shown. I thought the miui might re-lock my sim so I entered my unlock code. Then it said, "andorid.com has stopped". All i could do is to forget the unlock and went on to the miui home screen. After that my phone cannot pick up any signal at all. I used nano backup to restore my original CM9, everything seemed to work fine but it just couldn't pick up any signal. I went to mobile network settings to select the netwrok operators, it failed everytime. I tried entering 2945#*930# in dialer, it only said "Mobile network not available".
I tried to flash the same miui or my CM9 rom again, but my phone still couldn't pick up any signal.
Thanks if anyone can help.

Have you checked your APN settings?

you may need to reflash another baseband as CWM doesn't backup baseband so your phone failed even after restoring. I think you can find the cwm-flashable baseband on the forum.

I set and save the APN but the APNs page remains blank after I have entered things like PROXY, MCC, etc.

Thanks for the reply. I found Drumist's threat about those CWM flashable baseband. I tried the v10j and the v10f, but none of them work. Sorry for asking this dumb question but what should I do next?

Someone else commented before about their phone re-locking itself without explanation. The solution was just to unlock it again. I'm assuming you still have the unlock code?
The problem is that custom ROMs are incapable of unlocking the phone. You have to return to a stock ROM to perform the unlock, after which you can then return to a custom ROM. The stock ROM can be a CWM-flashable version for convenience.

1. 2945#30# is to bring up the sim lock page, where you can enter your unlock code. But it seems to me it doesn't work when your phone is already unlocked or you have a custom rom (just like what Drumist said)
2. I wiped it every time I flash a new rom just to make sure my phone is complete "clean", but I have no idea what it does :silly:

Seems you are having the same problem as I do. Simply flash back to stock rom and then enter the sim unlock code again, then your phone should be back to normal.

Fails to connect to network

unlocked GSM gnex. I believe it was previously used on At&t in the US. Currently has a T-mobile SIM. For whatever reason, can not connect to the network at all.
I flashed it to stock 4.3 yakju images, and updated the radios to I9250UGLL1.
SIM card definitely works.
Any other ideas?

Do you have a valid IMEI?

I found flashing the ROM your on again usually works.

Reboot to bootloader and check which variant do you have. Maguro?
To be 100% sure, please post all info from bootloader screen.

I317m sim relocked after flashing 6.0.1

The problem was resolved after flashing stock, reunlock, then restore. I will report if problems comeback.
Hello,
My phone was unlocked (not sure how, bought it second hand years ago) and used it fine on 4.4 custom rom. Ive updated it onthursday to the revolution 6.0.1 (with 3.0.2 twrp, nano open gappsa) and used it fine without problems on thursday.
However, yesterday, it lost cell signal and would not reconnect. So i rebooted the phone and now it is asking me to put sim unlock pin. What is the best course of action to get unlocked 6.0.1? I couldn't find an unlock method for 6.0.1. Should i backup rom, go back to 4.4, unlock, then restore?
Thank you.

It's asking for the sim pin or network unlock pin?

SIM Network unlock pin. My modem/bootloader is I317MVLBMA3. Do you think i can safely load a 4.1.1 rom and unlock again?
If i install phone info+ and look under secret codes, it does list the code for unlocking, but if i click on it, it gives me a blank page titled "service mode" but doesn't do anything (none of the three methods of entering work under the app). Probably because it is not stock ROM?
I tried searching for stock I317MVLALJ2 ROM to downgrade easily, but it seems like the link is down. I guess ill have to use ODIN.
EDIT:
Can I use TWRP to flash http://stockroms.net/file/GalaxyNote2/SGH-I317M/I317MVLALJ2_I317MOYAALJ2_RWC.zip stock ROM? Or do I have to use ODIN? I am assuming I can as it is a zip rather than img, and as long as I flash recovery right after flashing rom, I shouldn't lose recovery either?
Thank you.

The easiest way would be to flash a stock 4.1.1 rom in Odin. I am fairly certain you can downgrade as I think I downgraded from 4.3 or 4.4.2 on a Koodo note 2 so I could use it on Rogers. If it's not possible to downgrade, Odin will stop.

Thank you for the reply. I am currently on 6.0.1, but since modem is 4.4.2 ish, i hope that's okay. I will try ODIN. The zip i mentioned above is not a TWRP flashable zip, so I guess I have to use ODIN. The thing that worries me, though, is the fact that I cannot get to the recovery mode from off. I press and hold the volume up-power- home combo, but it keeps on resetting without entering TWRP. The only way for me to enter recovery right now is using a custom rom restart menu. If I go to stock ROM, I won't be able to access the recovery .
EDIT: If I let go of the power button at a certain time while booting, it seems to go into recovery just fine.. The problem is, that timing is tricky.

For flashing a stock rom, you need download mode so don't worry about getting into recovery.
To enter stock recovery, power off and try holding power, volume up, and home. Once the phone boots, let go of power but keep holding home and volume up until you see the dead android, then let go of all buttons.

Thank you. Flashed stock using ODIN, rebooted, showed samsung logo with music (stock boot animation), then the phone is stuck on SAMSUNG logo changing colors. Stuck there for the last 10 minutes... Not sure where to go from here ..

Boot into recovery and do a factory wipe.

Success. Thank you very much. So I've done the factory reset and successfully rebooted the phone. Then applied the unlock method, which seemed to have worked. Does not ask for SIM unlock pin. However, it does not seem to actually lock cellular signal. It still says 'Emergency Calls Only'. I am on Mobilicity, which used to be AWS, but now I believe is under Rogers. I know mobilicity used to take a while to connect, but I doubt that is the same now. This may be due to the old modem, so I will try updating the modem back to the 4.4 one... wish me luck
EDIT:
Without the modem update, it just connected to mobilicity !
Now the issue is, whether this phone will re-lock again once I flash 6.0.1...
Thank you very much audit13 for your live help!!
I will post back in a week or so (hopefully I remember...) whether this unlock sticks.

The 317m does not natively support was frequencies. You'll have to software enable was support.
You mean it doesn't ask for network unlock pin?

Yup. It unlocked for sure. But that is no different than what I had before updating to 6.0.1. I've used the phone without problems on Mobilicity for 2-3 years.
Mobilicity is no longer AWS, so it has no problems connecting to the network. It just takes a while, especially with the 4.1.1 modem...
Now I'm just restoring the TWRP backup that I have made on 6.0.1 to see if the unlock sticks.

The unlock stayed for my phone when I installed a custom rom.

Yes, that was the case yesterday as well. It stuck for a day, but after the cell lost the signal once (zero bars, emergency calls only), the phone got re-locked.
Now that I have restored the 6.0.1 backup, the phone is back up and running with it unlocked. Now ill will see how long this lasts.
Thank you very much for your continued support

I am having this issue now.. but the strange thing is that I've flashed to the Resurrection 6.0 rom a while back and it was working fine. Until a while ago I was pokemon hunting and all of a sudden my network died and its been asking me for a sim network pin... I was getting the intermittent network disconnect when I was on the Pokemon go app too long but it would reconnect back to the network after a short time.. not sure if it has something to do with the game app. Well, now I've downloaded the latest Resurrection rom and flashed it again doing a factory wipe but still nothing. I'm going to try and flash the modem and see if that helps.
EDIT: forgot to mention I'm on Koodo network which is also Telus, I believe. But now it wants to automatically connect to the rogers network hence I'm assuming its asking for the PIN.
(edited for grammar)

This is really strange that this happens. I've unlocked a few note 2 phones and none of them have relocked.
Did you change the csc in the phone settings to Koodo?

do you know why I cannot do the universal unlock method by entering the *#197328640# method? when I enter those digits nothing happens..

What's the csc you mentioned?

Csc is a carrier customization file. If you change the csc, which can be done using a stock rom, you can choose the carrier for whom the rom phone was intended. I choose Telus as a carrier because they have very little bloatware.

Locked bootloader, no baseband, greyed out OEM unlocking after flashing OCX27.109-36

Hello,
I have a problem with my Z2 Force TMO US version. I live in Poland. I bought the phone on the internet and it was TMO simlocked. I did the temporary unlock to check if it is working. Then I wanted to flash custom rom (DU in this case) and my problems has begun.
1. After first attempt of unlocking boot I got it unlocked but couldn't flash any custom rom. I figured out it is TWRP problem (flashed 3.2.2-2 not 3.2.1.1).
2. Flashed TWRP 3.2.1-1 and I was able to flash custom rom.
3. After flashing custom rom I lost phone signal: I'm getting no service and zero signal bar. I checked *#*#4636#*#* and noticed that I have radio off. I had IMEI and BASEBAND then.
4. I tried many other roms to get my signal back but no success.
5. I flashed stock TMO and was able to unlock simlock temporary again but it has no service and signal again. Radio is off.
6. Today I tried flashing stock OREO OCX27.109-36 with locking bootloader now I'm stuck.
I have locked bootloader and no baseband which means I don't have any signal or WIFI (mac is 0). I can't connect to google account so I can't get oem unlocking option - it's greyed out.
Can somebody help me with enabling OEM unlock? Or even better can somebody help me with getting signal back?
Thanks in advance for reply.

Try flashing the newest TMO firmware, which is the only thing you can flash with a locked bootloader. Check post #2 of the return to stock thread for the flashall utilities and the TMO flashall. The latest firmware provided for TMO is ocx27.109-51-7

You can do it
, I already had this issue with my moto z2 force in Morocco , so what I did is I connected the phone to internet via bluetooth and when I added my google accounte the unlocking oem in dev option was normal , so I was able to flash roms again . Hope this will help you.

Use pdanet app, you need two Android devices. Connect using Bluetooth...

Thank you guys. BT tethering helped. Thread can be closed.

How did you connect to Bluetooth to get through first start up? I can't get to Bluetooth settings to pair. I have this issue currently...
