I live in greece and have a vodafone sim.The phone is unlocked and worked perfectly.
Today i tried to put another sim and it didn'y read it so i tried to change the band (to 1900 from 900) nothing happened.
So I wanted to restore the band but then i realised that i couldn't access the band tab because it wasn't there.
There are no phone settings to change
I tried a hard-reset but nothing changed
Now every time i try to reinstall the T-mobile ROM 4.00.21 i get an error message telling me something about the connection while the same time activesync is on.I put the rom in the SD card but nothing appears.
I'm depressed and don't know what to do
Is there a way to change the band to 900
If not how can i install the same ROM or an older one.
I'm crying for help
Please help!!
1)In case i forgot now it has 1900 band selected
2)when i open thephne it says something to turn on the wireless radio and prompts me to enter a code i think what do i do there
Other times the phone wont open at all
Use the GSM band selector from the boot loader GSM menu
Could you please tell me the steps to do that.
I'm not very experienced with these thing.
The more you analyze the easier for me.
to get into the bootloader
you softreset the device while holding
down the power button
i got in the bootloader then...
IT says :
WALLABY Bootloader V5.15
GSM OK
By pressing action :
GSM TURN ON
already on reset
???
hi there, my atrix does not want to register at operator.
My phone was always trying to use 2g cause of better signal.
I went to Admin menu (*#*#4636#*#*), changed to WCDMA preffered, but in about a minute it did not change. I tapped function key and then Select Radio Band, it was only USA - i tapped it.
So he do not even try to register at any operator.
but i can call 112.
there is no any band other thsn USA.
Our band are almost same
900/1800/2100
So at least some operators must register.
may be i can refresh the modem part via bootmenu?
Or is there a way to reflash the modem part?
thanx
motrola forum - https://supportforums.motorola.com/message/353262 same situation, but with other ppl.
i found a solution...
1. backup via CWM
2. phone reset
3. restore backup.
Hi everyone,
First post on XDA after years looking for solutions for my smartphones here.
I was playing a bit with my Archos 50 Diamond (dual-sim, 2015), in order to use it as my main phone, as my current one is slowly dying. I purchased a new touchscreen I replaced myself as the former one was broken, and tried to put my SIM inside. No signal.
I tried a factory reset. Still no signal. SIM was detected, asked for PIN, but no signal. After searching in several forums, I managed to arrive on Radio Info settings. (code through dialer is *#*#46363#*#*, anyway I cannot access any code through the dialer, don't know why, so I arrive there using an app downloaded on Play Store)
As I was playing around, I chose "Choose Radio Band" and selected USA Band. Big mistake. All frequency were gone (GSM, LTE) and the "prefered network" option is stuck on "WCDMA only". Of course, I live in France, we use GSM/LTE frequencies, so no signal.
Moreover, the "Turn Radio on" button doesn't affect the radio cells.
After a few factory resets, I already tried the following :
- erasing modemst1 and modemst2, through fastboot. It resulted only in erasing IMEI, great. I restored IMEI through "IMEI changer.exe" I found on the web. Both IMEIs came back.
- enabling all necessary bands through CDMAtool (or Qualcomm QSPT/QXDM tools, it's the same process, using Android Diagnostic Mode) - All GSM/LTE bands will appear on the smartphone using an app like "Network Signal Guru". After that, I can change "prefered network" in "Radio Info menu", so this is better that stuck on "WCDMA prefered". But the SIM is now undetected, no PIN is asked, so I cannot even verify if signal is back.
- Adb shell su -c "radiooptions [arguments from 0 to 8, 0 resets, 5 turns on)" _ using option 5 will actually turn Radio on, but no effect on if the SIM is detected or not. By the way, it turns radio cell for 1st SIM, but not for 2nd (we can see it in "About Phone, State" in phone settings)
- Tried to edit build.prop in order to see what I can do, but I couldn't see no effects either.
- Tried to flash NON-HLOS.bin, but didn't help either. I couldn't find fsg file inside my factory firmware image zip.
So for now, I know how to enable bands I need with CDMAtools, and turning on/off radio cell through adb shell or Terminal Emulator. However Radio Cell will turn off automatically on every reboot, need to turn on manually everytime I boot.
But SIM is not detected at all. I'm not sure if there would be some signal if SIM was detected, but it would be great if I could figure it at least.
Phone is rooted, STOCK firmware Android 4.4, no existing custom ROM, can boot into CMW if needed.
I've tried a lot of tutorials, I don't even remember which ones I did or not, but I'm pretty sure I couldn't find solutions on XDA or stackexchange at this moment.
If you can help, thanks in advance
Cheers
Samuel
Hello. is the replay to this post?
I have asus rog phone 6 and have same problem. after mess with "SELECT RADIO BAND USA BAND, cannot access internet. tried the soltioins from online bootloader erase modem. but not access. when I boot into bootloader it stuck on wait for any devices. asus rog bootloder does not have any settings, its empty.
anyone can help?
Here are the symptoms:
When going into the network settings and pressing choose a network operator, it says "Error while searching for network"
If I select "choose network automatically", it says "registered on network" but nothing changes.
When I tried to make an emergency call, for example, it tells me to turn off Airplane mode. However, if I scroll down the notification bar, Airplane mode is OFF.
In About Phone> SIM Status>:
Network - Unknown
Network type - Unknown
Service state - Radio Off
Signal Strength - 0dBm 99asu
Network State - Disconnected.
IMEI IS THERE. NOT CORRUPT.
Dialing *#*#4636#*#*
Will not let me change preferred network type.
Pressing Turn On Radio does nothing.
Neither does updating smsc.
I did what anyone with common sense and a little research would do.
Reboot phone
Remove/insert sim
Tried my dad's sim, which is on a different carrier.
Tried slot 2 as well
Wiped cache partition
Then as a last resort, full hard reset. I have wiped dalvik, system, data, user data and cache.
...But to no avail.
Restore qcn from other device still not fix error
Restore qcn from other device still not fix error
Maybe you need to update baseband firmware
I can't get the data connection to work at all, and it won't even connect to a 4g network even when the signal is strong. Mine is a H930DS (Joan?)
I just reinstalled the stock pie using "H93031a_00_OPEN_EU_OP_1105.zip", I installed in TWRP. I followed the instructions on the first page of this thread .....
I have tried various custom roms on this phone but this stock pie is one of the very few that even recognizes the sim card. I settled on stock pie inspite of the bloatware.
The problem happens when the rom is brand new, before ANYTHING is disabled or removed.
When I choose to search for a Network Operator (using the 3 Network sim) I get a "3 RAT-4G" and a "3 RAT-3G" listed and it will never connect to the 4G if I choose that one. It will only connect to the 3G. Even when the signal is very strong (5 bars). When I opt to connect to the 3G network then I get a stronger signal if I choose "GSM/WCDMA auto" in "settings>>network>>mobile netwroks>>network mode" but still no data connection
THESE DIDN'T HELP
1 - using ADB and restarting the phone in bootloader. It was to reset the modem I think. There was a series of 3 commands to follow. i can't remember the details of this method but I think one of the commands included "fastboot erase modemst2". I tried it and I was getting the same error message that other people reported and it didn't go anywhere.
2 - The following solution didn't work either..............
"re-loading IMS settings using the LG Hidden menu: Dial *#546368#*930# using the stock dialer -> Field Test -> IMS Setting -> Test -> Load Preset Configuration -> Initialize Configuration. Then back out twice to Field Test -> IMS Setting -> Test -> Restart IMS process. Give it a few minutes."
3 - Resetting network settings didn't help either (Settings -> General -> Reset -> Network settings reset).
4 - Changing APN, or network bands (in settings ... choosing "LTE/GSM/WCDMA auto" or "GSM/WCDMA auto" or "WCDMA only")
5 - Changing "set preffered network type" in engineering mode settings (accessing using *#*#4636#*#*)
How can I use data connection on my H930DS?
Data modem works now!
SOLVED!
My phone has bootloader unlocked and TWRP revcovery. That's obvious I know but I only say it again in case anyone tries this with a locked bootloader and using a stock rom that has never been flashed. (I have to warn you that your results will be different, your rom will be reset for sure an your data will be wiped).
I tried so many things, flashing up and down from 8 to 10 but Stock Pie was always the least buggy for me so I persevered with that.
I think this solution reset the hardware, but I am no expert.
The solution is basically a "Factory Reset (R&D Only)". They warn you against it but with my configuration all it did was reboot the phone into recovery and then left it for me to decide what to flash or wipe, as per usual. What I only realized later, when I rebooted into system (without changing anything in TWrP) was that it had reset the hardware, or reactivate data connectivity. NowI have 3g data connection and 4g connection.
THE SOLUTION
*the following 4 lines are a direct quote (my phone's os DID NOT reset)
1) Backup everything, as the phone will be wiped. If yours is a network unlocked carrier model, make sure you have an unlock code (or unlock approval if T-Mobile).
2) Remove your Google account to disable Android Device Reset Protection.
3) Dial *#546368#*930# (replace 930 with your model number). This should open the service menu. From there SVC Menu - Factory Reset (R&D Only).
This takes quite a bit longer than normal Factory Reset. Your phone is now TRULY back to factory state.
I took out the sim and sd card before I committed to the reset. But like I said, it didn't wipe anything (maybe it would have wiped my sd card but I am not testing that). It just booted into recovery and when I rebooted into system I found that the data connection was working. Now finally it is a smartphone!
