[HELP]how to recover from USA band? already tried to flash radio. - Nexus 5X Q&A, Help & Troubleshooting

hi all,
I select the usa band in *#*#4636#*#* accidentally, but I had tried to flash the radio through fastboot, it is still not able to get single from 3G/2G.
I had tried to flash the 6.0 radio than flash 6.1 radio, but still not able to get single back...
need your help to give me some advise, my 5X had been rooted with system less root, is this make any difference?

[Q] So How does this actually work?

I picked up a pre-owned Gold G3 yesterday, my last one went pop!
This new G3, is Sim Unlocked, but with a Vodafone UK rom (V10a.235.15). After researching and reading around.. the G3 has EFS, so I followed the KDZ back to stock guide and flashed the Open EU rom, which went without any issues and seemed as if it had flashed and replaced the VF Rom, but it still has the VF splash screen, a VF updates Icon (Which can be removed) and software version, yet the G3 still detected and Loaded in my EE UK APN settings and no sign of any VF APN.
http://forum.xda-developers.com/showthread.php?t=2785089
So am I right in thinking.. If I wanted to make this a full UK unbranded phone, so no splash screen with a software V10a.EUR.XX.. I would have to Jailbreak the EFS partition and Replace VFRom stored on the EFS with the EUR-XX rom.
OR am I wrong entirely, so... How does this work
There are so many threads on here, that ask the same questions in different ways, hence why Im a litle confused as how this works
Thanks
Wait Wait Wait
So you cant manually import APN settings right? How about flashing a Rom from another European country?
Dont tamper with the EFS partition under any circumstances. If you do you wont have a IMEI and your phone will be worthless. Carrier branding does not occur within the EFS partition
I remember my carrier apps disappeared from Update Center when i upgraded my Australian firmware to a Taiwan Firmware so im pretty sure it might work for you.
When you flash the KDZ make sure you flash it using CSE Flash Mode

Can I just be clear before I answer... The G3 I bought is Branded to Vodafone UK, I am personally on EE UK and Im trying to remove the Vodafone Branding and make it a factory unlocked unbranded G3.
Thanks for the reply friend. I didnt have to enter any EE APN settings, they were already there, so not sure how that was... because I didnt enter them. Glad to hear its not the EFS, because I would rather use a branded phone and have it working than change its file system and mess it up. Also, I know the guide doesnt state it but I turned ON USB Debugging, would that make a difference
I followed the guide closely so did flash using CSE. Ill now flash another countries KDZ and let you know how i get on?
Could it be that Vodafone UK is the EU Open Rom, just a few minor changes..... What I dont understand is...
The EUR Open Rom flashes perfectly fine, reboots and starts... so why after a perfect flash using CSE, is the Vodafone UK rom still there. Any Ideas.

Im afraid no Luck... I flashed Open France, still booted to VF rom with VF software on it v.10a-235-15), then installed "Italy Orange", which actually worked, booted up a clean LG rom BUT, even though its v.10a, When trying OTA update, it said I was n the latest OS, which is no good, then using LG PC Sync.. it just updated to the UK VF rom again (20h).
So I took a long shot and flashed Open UK, still the same.... boots into VF splash screen and software.. so, Im at a loss. This is why I reckon carriers hide a rom on the EFS partition.
Any thing to add
Thanks

Airplane mode will not turn off

Hi all, I've been battling this problem for days now. Airplanr mode is stuck 'Turning off...' and wont connect to my mobile carrier. Things I've tried:
Restarting phone with and without SIM inserted
Factory reset from settings
Factory reset from recovery mode
Flashed to the same build twice using the flash from SD card method (build 3.36.709.3)
Turned airplane mode on and off with wifi/mobile data/NFC turned on or off
I have no idea what to do next. I doubt it's a hardware problem as the phone detects the sim card when I put it in and asks if it's O2 pay and go or pay monthly, so it can even read it, it's just the phone wont come out of airplane mode.
I am on holiday without a PC but feel free to post ideas that requires one. Device is currently S-on and unrooted. I would rather not root or s-off the device just yet, and would rather stay on stock ROM as it's still in warranty. Problem is, it's in the UK and the warranty is held in Taiwan, which means sending it internationally to get it fixed. It's also a problem as there is a language barrier between me and their support for phone calls and their live chat button appears to always be greyed out.
Edit: I found this for the M8 which I think is in the right direction:
"Even I started thinking same way but it wasn't hardware issue.
I used ##786# to reset the phone completly (it did asked me my MSL/SPC) and everything was wiped from the phone. ( I am sure this reset is different from normal factory reset)
now my phone is up and I can toggle Airplane Mode On & Off however now there is another thing which I came accross
1. No roaming option or extended options in "Mobile Data" option under Wireless & Settings
2. No Network Sharing option
Even tried after running RUU_M8_WHL_K44_SENSE60_SPCS_MR_Sprint_WWE_Harman_2 .16.654.4_R2_Radio_1.08.20.0612_4_NV_SPCS_1.52_003 _release_384670_signed_2"
How do I do this with the M9? aLogcat comes back with no MSL so I need a free unrooted way to get that, and that # code doesn't do anything on the M9 either!
Edit2: Tried*#*#4636#*#*
Option is there to turn on the radio, but pressing it does nothing. Changing preffered network type does nothing either (I select any option from the drop down and the original choice remains). SIM is with O2. Currently set to GSM/WCDMA/LTE
Please help -_-
damn you really tried an m8 RUU on M9? please don't be stupid! it will never work lol. is your phone unlocked, so you could flash twrp recovery? otherwise you need to find a RUU matching your mainversion/CID. but this time not from m8 lol

The M8 RUU was a quote from someone having the same issue on their M8. Sorry if that wasn't very clear. I am running a fresh M9 latest RUU, I'm not dumb enough to put an M8 RUU on it and the stock flash utility (download mode) isn't either.
I still haven't found a solution to this. Can anyone help?
tried in *#*#4636#*#* on the menu button the frequency option? if you are fully stock, ask HTC, if they have no other fix, send it for warranty
I've tried everything in that screen. Here is what I have also tried today:
Bootloader unlocked
Custom recovery installed
Rooted
Model number and CID changed to developer model
Developer rom installed (android lollipop) same problem
Latest developer edition firmware installed
ViperOne 4.3 installed, same problem
Cryno... Something... I forget the name, but another custom rom installed, same problem.
It's fair to say that the problem is probably hardware related. The SIM card is detected, but the radio willnot turn on. In this instance, what is the most likely hardware cause? Is it worth replacing the sim card reader or is it more likely to be a chipset issue? I would be happier replacing the sim reader if the sim was not detected at all.
Btw, all the custom software stuff was done because HTC Taiwan said they wouldn't touch it. According to them it's out of warranty even though UK support say it's in warranty with the taiwan support centre.

KDDI Marshmallow update WARNING.

I was running the Taiwan ROM on my phone but went back to the Japan version when the Marshmallow update was released. Now the phone is screwed
It started off with the phone asking for a 'Network subsystem code' so the phone was essentially network locked and could only be accessed if the SIM was removed. I re-flashed the Taiwan ROM thinking it would go back to how it was but it still asked for the unlock code.
Maybe this was where I went wrong, but I bought an unlock code from eBay, entered it but after it rebooted it still asked for the code.
I tried a few TWRP backups but nothing worked and now it doesn't recognise a SIM at all. Nothing.
It's randomly restarting and I've also noticed that the IMEI number isn't showing up in the settings.
I have no idea what to do so if you have any ideas, please let me know...
Possible Fix
Try to flash misc.img. Its supposed to fix simlock for the taiwan version, and its the same image for both. You can find it at the bottom of my conversion guide.
Don't worry, you should flash your phone return to rom stock KDDI 5.0.2
then flash file fix sim pass: 8jtv
by adb change.
Code:
fastboot reboot-bootloader
fastboot flash misc misc.img
fastboot reboot
or unlock sim by xtc2clip
I have got no signal after I change my sim in KDDI 6.0 rom. I am sure that my sim card (UK sim) is not damaged, but my phone is not able to register to the network. I am now thinking of flashing back to JP 5.0.2 again
How about Taiwan?

If you dont need nfc, the taiwan ROM is better in every other way.
http://forum.xda-developers.com/butterfly-3/development/stock-rom-stock-5-0-2-cure-t3356875
or if you NEED to have nfc, you may need to manually scan for network(s) in settings and after that replace the apns-conf.xml file with one from cyanogenmod or any other universal rom, because data only works on its known network (au). You will also need to change from SMS to Messages apk and maybe change the call center number. (stock htc text messaging app)

Did you solve it finally? I had the same problem, but I solved It by flashing a ROM on fastboot.

Was on oreo and did flash all to 7.1 by mistake.

So I was on Oreo and accidentally flashed back to 7.1.
Didn't brick it but now it doesn't recognize my sim even after flashing back to Oreo.
I tried to fastboot the tmo baseband but no luck there.
Anyone run across this or have any suggestions?
That was one of the 1st thing I ran across in the Oreo update thread. With development just really getting fired up I'll be surprised if you find a fix. If. I was you I would flash the mod that hides the unlocked bootloader warning and take it to TMobile. It's only a 5 dollor charge for defective devices. I've returned a total brick before.
So I am on the same board. The problem is I'm in UK and I cant claim warranty repair. Also my warranty was void in December soon when I generated bootloader unlock key.
SO what have I tried so far?
Hard brick bootloader to state when it is Qualcomm loader- only blank flash and Oreo Flash All is able to bring it back to live.
Ive also tried boot from B slot in twrp but it looks like my B partition is messed up. Fastboot will show red warning about no flashable A/B slot and only oreo flash can get it back to boot because it will oem lock itself.
When I get back fully on unlocked bootloader to 7.1.1 I cant update via adb sideload or update menu in settings. Both will fail.
Sim looks like it is detected on start but when taken out and slided back in it wont show up.
I have QCN area backed up with nv data but it wont help me.
Please note when boot is bricked oreo flash all will flash it on locked bootloader and will not show warning screen at all about botloader. However I was unable to boot to recovery from that point so I had to unlock it and flash 7.1.1 then oreo again.
So if someone could do nandroid backup of clear not set up rom it would be great. I can try restore it. I dont even know if twrp is able to do backup on A/B device.
Also if someone could read NV data from phone and share it ( from phone with working radio of course) would be really appreciated.
Can someone PM me NV backup? I need urgently qcn file. I think my hw partition is messed up. Please don't share it in this post as it can contain IMEI.
this is what i did, and why there is a giant post in caps in the thread that says not to do this. You essentially end up with a bootloader mismatch which hoses the radio. the only solution is a replacement.
and DONT DOWNGRADE !!!

Sorry but warning isn't clear. I did not enjoy Oreo and was looking for unlock method.
Also bootloader match to my current Oreo rom and radio but still no sim detected so I think it is hw partition messed up. When I flash retail Oreo on it bootloader just change itself to retail Oreo version. Still no sim.
Device is useable as paperweight with WiFi
I think I've found a way to unbrick your phones guys!
If someone still has their bricked phone could they tell me what state they're in? I managed to successfully unbrick mines but had to stay on 8.0
Everything about the phone works 100% except the Sim slot. It's like it can't read the Sim. It knows there is a sim in, but it can't access it.
On Oreo oem retail version.

I'm happy to stay on 8 but need my sim get back to life. All works fine except SIM card is not detected.
My phone boot as normal. When downgraded it won't accept ota's. It won't install it via sideload too. SIM card remain undetected no matter what rom and what version( T-Mobile, retail, etc) when I try to boot from slot B via twrp it won't boot. It will show bootloader screen with unbootable a/B partition.

Not OP, or guy with a link, but I did a similar bad thing and ended up on the retail Oreo without working SIM. What I did was take the modem file (the one that you fastboot flash to modem) from the tmo oreo zip and replaced the modem file in the retail oreo zip with the tmo one -- just change the name of the tmo modem file to the one that comes in the retail oreo zip and then run the retail flashall.
Still no way to get the latest tmo update that fixes some volte issues, though. Since I purchased within 14 days, I just added insurance and will probably end up drowning the phone to replace it... unless someone has a better idea. :/

this is the retail oreo:

guys i tried blank flash oreo on mine bricked tmobile moto z2 force and it isnt working, any help would be great on this , thanks.. and also i have tried many blank flashes some for even other moto phone models none worked so far.. one or two of them got really close the oreo one did but failed at last part... tried about hundred times and yes i even tried holding down power and volume button with no success it didnt work it did though recognize the phone but still failed trying to boot or flash it though... seems to me it needs either up to date or just different blank flash it seems, but i dont know that for sure...

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...
