First I'm on official build. Not rooted and my phone is a520f/ds uae.
Yesterday I woke up to see my phone has no signal on both sims(different carriers)so I unlock the phone and it rebooted into a boot loop until I took simcards out.
Now I only can have 2g on both sims to function normally or either it reboots or says emergency calls only.
I flashed it with latest builds a couple of times and no lock.
Please help me.
HELLO?
Undo any debloating if any.
Install the stock rom of the firmware CSC relevant to the SIM and enter the stock recovery.
Contact your mobile network operator.
Create a backup and wipe data...
I do not recommend anything efs/pit, a backup is OK.
There are at least 3 tools to identify what's wrong with the cellular, while it's on the "emergency calls only"
Logcat, specifically logcat -b radio, can be used without root (usually adb), look for errors, if it can't be filtered by the radio log, search for "RIL" in the entire logcat.
*#0011#, look for mcc (mobile country code) and mnc (mobile network code), or plmn (both), for example mcc 310 (US) mnc 260 (T-Mobile). It should match the SIM, or try a manual network selection in the settings. Though this shouldn't cause a restart, RSSI is the signal strength of the frequency, RSRP/RSCP is the approximate signal strength of the cell, RSRQ,SINR,ECIO,rxqual are signal quality.
*#9900# (it is not 9090!) > run CP based log > copy to sdcard. It's in /sdcard/log/err, (internal storage)/log/err, /data/media/0/log/err, /storage/emulated/0/log/err.
LitmusLog: Scroll down to "### SIM1 Reject Information ###", a history of the error codes are below. For example, Cause:1. The plmn is basically backwards.
Protocol: Look for "attachreject" "t___ out of sync" "rlf unrecoverable", etc.
Cp_members: look for anything other than reject cause=0x0, and any error. Below the plmn, which can be seen with hex to ascii.
Then search for the 'error', or send it to your mobile network operator.

Hey guys,
My phone stopped working about a week or so ago and I tried everything to fix it, nothing worked, stumbled upon this thread: http://forum.xda-developers.com/showthread.php?t=1045869
And decided to check if my IMEI was blocked (it was), I called Tesco Mobile, asked them to unblock it, which they did but I cannot make any texts or calls. I have tried:
-Reflashing radio
-Reflashing ROM
-Factory Reset
-Leaving battery out overnight, putting it in the next day
-Tried SIM in other phones - it works in other phones
-Reinstalled stock Sense ROM
The strange thing is, I can use the internet but cannot make texts/calls. Advanced info via *#*#4636#*#* shows:
IMEI: same as on phone
Phone Number: correct number listed
Current Network: Unknown
Singal Strength: 0
Location: LAC = unknown CID = unknown
Neighbouring CID = unknown
Roaming = Not roaming
GSM service: Disconnected
GPRS service: Connected <<< WHY IS THIS CONNECTED AND GSM ISN'T?!
Network type: unknown
Message waiting: false
Call redirect: false
Radio resets: 0
Data attempts: 0
Data successes: 0
If I try to change the network to anything other than GSM only then it just reverts back to GSM only. The SIM works in any other phone, my phone IS unlocked, was working perfectly prior to being IMEI blocked, so what appears to be the issue? I called up Tesco to confirm the bar is removed and they said it is, so, what gives?
EDIT: I can happily browse the internet while out and about - no wifi, definitely GPRS as I use it while I am away from my home wifi/any wifi I connect to. I am confused as to why I can use GPRS but cannot use GSM...
maybe bad sim?

SIM works in other phones and didn't have a problem with it previously... As in I can make calls and texts if I use other phones but only internet in the HTC Desire... :S
My phone was working fine for a week or so. I had flashed a Legacy SERO phone over to this phone. Suddenly today the 3g icon disappears and under phone status, the mobile network state is always disconnected and I no longer have 3g data or MMS. Voice and SMS work fine.
The original donor phone works fine too (3g / MMS).
I've tried:
- flashing back to stock
- trying to reprogram NVItems (HA/AAA/Mobile IP stuff) back onto Note 2 (I think they were already there and I didn't change them, but it still doesn't work)
- tried to copy the APN for the donor phone over: but I cannot find a way to program APN on the Note 2, and isn't APN for GSM anyway?
- tried to copy the PRL from the donor phone over: but I cannot find a way to program PRL (tried DFS 4.0.1.1, which cannot read nor write the PRL)
This is really frustrating without data, can anyone help?

If anyone else runs into this, here's how I fixed mine:
I believe the problem was a combination of APN settings and the phone trying to go into LTE mode (which I don't have as a SERO classic user).
I had to turn off eHRPD and manually force the correct profile to load. I did this with:
##3282# => MSL => Edit => eHRPD (turn off)
then ##3282# => MSL => Edit => Others => LTE APN Settings => 3rd option (LTE - Sprint OTA). Oddly, before this change, none of the three options was checked, that could have been the source of my trouble.
Put it on CDMA mode only.
No cdma/lte. That will not work
I have received a p607t tablet, it was flashed by smb. to p905 firmare (with no imei). i re-flashed it with stock P607TUVUBOI2 firmware (4 files, so-called "service" firmare), imei is back (to what is printed at the back-side) but mobile networking *still* doesn't work: no connection. I'm using not t-mo sim-card, but looks like the tablet was already unlocked
From service menu *#0011#:
SERVICE : LIMITED
NETWORK : UNBLOCK
IMEI Certi: PASS, 1
From Advanced Signal Status:
Carrier:
Network Type: Unknown
Signal info: n/a
Neighboring CID: no neighboring cells --- wtf? >> other devices work ok with this sim in lte and 3g modes<<
GSM service: emergency calls only
GPRS service: disabled
Any ideas?
OK, so, what is done with p607t to the moment:
1) reflashed CP (modem/RF??) to latest stock (P607TUVUBOI2)
2) reflashed AP/PDA (core system??) and CSC (consumer stuff??) to P605XXU1EOI5 (from p605, have one right here - it never had network-lock from factory)
3) using qpst and qxdm changed nv parameters (extended lte bands, enabled gsm rf-bands - there were none in stock at all, only wcdma)
now the tablet sees my local gsm network with this sim-card, signal is 4/5 bars, but still no internet connection - WTF??
p.s. when trying manually to register in my local network - it fails with "try again later"
p.p.s.: what is i find weird, in service menu *#0011#:
NETWORK : UNBLOCK
- this line exists only on p607 - is this the key?
Then, i insert this sim into p605 (completely stock P605XXU1EOI5) - it works like a charm
need some help - where to dig next? point direction plz
UPDATE. i've been tweaking 607t nv items with qxdm, making it alike that ones 605 has. practically everything is alike now, but still it doesn't even try to establish data connection with cell...((
btw, 605 does not have "esf embedded file system", while 607t has one (can be seen through qpst-esf explorer)
also, some nv-items present in one model, some present in another

I had to flash back to the original kitkat firmware and take OTA to upgrade to lollipop. There is a known issue with the 607t losing data after roms are flashed. Some had luck with flashing the same rom twice but it never worked for me. Used Sam mobile to pull original and went from there. Good luck
I performed "device init and reflash" with Keis. The device is back to stock completely, except:
- nv items data
- esf embedded file system data
so... my guess - i need to restore these in order to have mobile networking working.
could someone post a qcn-file with factory esf-data?
ok, let's take another way: how can i get some gsm-module debug-output or log to understand, what's going on it?
i'm trying to write some custom modem.bin to /dev/block/mmcblk0p2, but after reboot data in there is reverted to stock modem.bin - how come?? is that bootloader doing? where is the stock-one stored?
I just installed the HTC_One_M8_GPe_Marshmallow-6.0_MRA58K.H14_AROMA-Installer.zip on my HTC Verizon M8. After doing so I can only get data via Wifi, it does not connect to 3g or 4g. I was wondering if this is a known issue if someone could direct me on what steps I should take to troubleshoot. I should mention that even though its a verizon phone I am using Smart talk.
Here are my current settings:
Preferred network Type: Global
CDMA Subscription: RUIM/SIM
Access Point Names : VZWINTERNET.
Network Operators : receive "Error while searching networks"
SIM status -> Cellular network state : disconnected
You used this version? http://forum.xda-developers.com/verizon-htc-one-m8/development/rom-vzw-stock-gpe-5-1-lmy47o-h9-t3212413
Did you do as the thread states:
[*] If you have issues with 3g/LTE data hand off, do a full RUU and do a factory reset with the stock recovery. Alternatively just flash the stock recovery and do a factory reset. Theory is the stock recovery rebuilds NV data. Getting a new SIM card has also been reported to work. Calling customer service and asking them to reset your connection has also been reported to help.
I'm having similar issues but I'm using page plus(Verizon network with Verizon m8 and only text and calls work but no data. Also using Verizon APN any suggestions
UPDATE: 4G/LTE wouldn't work without erasing all possible APNs except Ting's (with some messing around to get settings correct). LOS14.1 continued to throw errors with this install though so ultimately re-flashed with RR and it's working perfectly now.

I'm trying to port an S4 Mini SPH-L520 (CDMA) for use with Ting. Has anyone successfully done this with full access to phone, text and data? Having updated the carrier settings while stock, then flashed LOS 14.1 I've got functional voice, SMS, WiFi and can see 3G sporadically when I refresh network settings, but 4G/LTE's a no-go -- I get a "Your mobile data service couldn't be activated" error from the setup wizard every time the phone starts. It's definitely seeing Ting's SIM card because it's showing the correct ICCID, but won't work at all in RUIM/SIM mode ("No service", "Select SIM Card" with no options) and defaults back to NV. Haaaalp? I'm very computer literate but cell phones are terrifying and mysterious black magic...
