Anyone interested in unlocking their S6 it's fairly simple. Root and activate the hidden menu (directions are in xda verizon thread) and from the menu you can enable GSM. I have fully working voice,text and edge/LTE data. I have only tested on T-mobile
GUIDE TO GSM UNLOCK S6:
* Root Phone (Use Ping Pong root)
* Enable service menu
* Insert GSM SIM card
* Dial *#27663368378# -This will put you in service mode
* - UE Settings & Info
- Settings
- Protocol
- NAS
- Network Control
- Band Selection
* Make these selections above
* *Make sure you use the more button in the upper right corner to go back if needed(Back Key on phone will exit menu)
* Choose choice 7 “LTE/GSM MODE ONLY”
* Reboot
* Go to settings/Wireless & networks/more and it will allow you to add the correct APN
* Change preferred network type to LTE
Let me know if you need clarification. I don’t have the phone in front of me currently but am pretty certain that is everything
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
I have a Wileyfox Swift using GiffGaff in the UK. Everything worked fine, frequently got LTE speeds until I temporarily put in a new SIM into the second SIM slot to use a throwaway number, after doing this (and removing the temp SIM) I can no longer get LTE speeds on my phone. It now only connects with EDGE, HSPA and HSPA+ and frequently drops the connection entirely.
ROM - [ROM][7.1.x][Official] crDroid Android v3.8.5 [OMS][2018-01-17]
Radio image - radio-20161215-crackling.zip as recommended by ROM
Things tried with no improvement:
* Radio image from Android_7.1.1_Wileyfox_Swift_2017_04_21_TOS111B
* Various APN settings from GiffGaff website/forums
* *#*#4636#*#* - Setting LTE only drops signal completely
* *#*#4636#*#* - Setting any option containing LTE doesn't get LTE speeds
* New SIM from GiffGaff
* Updated ROM to latest version
* Wiped all partitions, flashed ROM and Gapps
* Put SIM into SIM2 slot
Any suggestions?
Is your currently active SIM in slot 2? I don't remember exactly but I think only SIM 1 slot had LTE connectivity.
Hi, I'm ready to donate to the user who can help me to get my local GSM carriers working in my used Samsung Galaxy Tab S 10.5 LTE.
It is pre-owned, clean IMEI (no financial problem nor blacklisted issue), and I can see the SPRINT user data everytime I flash the stock ROM (Sprint number, user Sprint email, etc). I'm running MM 6.0.1
I have flashed stock ROM > rooted (CF-Auto-Root) > unlocked and debranded (idoneapps app) > flashed custom recovery (TWRP).
After that I have tested all the setting I could find here and in ohter websites including:
- gsm.zip patch (installed but not working)
- DFS tools (new GMS/UMTS/LTE bands enabled succesfully!)
- Enabling Global Mode on Service Mode (nothing changes)
- Editing build.prop system file (nothing changes)
- Runing some adb commands (nothing changes)
Current situation is:
- Now I can see the new bands added (GFC Settings)
- There is not more the message "Connecting to netwok" on the top left corner
- APN configurad correctly
- The carrier signal icon is always empty
- I still can't set "GSM auto (PRL)" as the "Preferred network mode" under Radio Settings
- No internet connection at all (GSM/HSDPA/LTE)
Any solution for this?
