Is it possible to extract the radio image? I have converted my M8 to a GPe and when I did I remove the radio image from the RUU since it's a swedish phone with other LTE bands than the original GPe.
After a few days of testing it I seem to have problem connecting to LTE most of the times, but not always. I've read that people still can connect to LTE with the radio image from the GPe RUU and now I want to try that image instead. As a backup I want to be able to return to my stock radio again.
So, is this possible and how is it done? Or can I get the stock radio image in any other way?

Mind sound a little simplistic but couldn't you:
1) do a full backup
2) Download the GPE RUU
3) Extract the radio.img from it
4) Flash the radio.img "fastboot flash radio radio.img"
If it squirrels your reception up just do a restore from the backup?

Hmm yeah, that could work. How do I do a complete backup? And how do I restore it if I need to?

I'm using philz recovery but twrp is similar. To back up press on back up and select location for back up.
Reboot when finished. I always store the backups on the laptop as a safety precaution.
To restore, just click on restore and go to backup location on phone to restore.
I prefer TWRP but it gave me issues with OS disappearing ! (possibly)
As far as I know, the gpe has the same version of radio as the sense one.
I have the sense version and I am having issues with LTE, I would root and flash the gpe radio if thats going to fix the problem

As you know I am using the Gpe RUU and love it.
Radio works great for 3G/4G. The issue is 4G coverage is crap both here and where I work I do get it on the drive home lol.

It is not about the coverage here. I live in Saudi Arabia and I used to have a very good, consistent LTE connection using the M7, LG G2, Lumia 1020, Xperia Z1 & Xperia SP. But not the M8. This device only connects to LTE when the signal is very strong. And I am not the only person here with this issue. I have seen many people complaining about the M8 ability to connect to LTE network.
I hope its a radio issue as I really like this phone and I don't want to replace it anytime soon

But the GPe only exists in the US, so the frequencies are different in that and the European. Couldn't that be a problem if I flash GPe radio?

Compared to the Nexus 5 my M8 seems to have worse coverage. But my problem is that it's not connecting data at all when trying LTE. If I limit it to 3G it seems to work all the time.

And you use the GPe radio? What frequencies are your carrier on? 800 MHz and 2600 MHz?

To extract your radio image, do the following commands.
adb shell
su (if needed to get a #)
dd if=/dev/block/mmcblk0p20 of=/sdcard/mmcblk0p20
exit
You'll find the radio image on the internal sd card.

I believe that LTE frequencies are hardware related, not software. Someone correct me if I'm wrong

So the file mmcblk0p20 is the radio image? It's 75 MB.
How do I flash the GPe radio? I tried fastboot flash radio radio.img but I get FAILED: remote not allowed.
IMO, you simply need to edit the ril settings in build.prop to match what was on your sense Rom and lte connectivity will be restored. These are the lines that need changed:
ro.ril.hsdpa.category=
ro.ril.hsupa.category=
ro.ril.hsxpa=
Gpe sets these pretty low for some reason..

How do I know what was set there on Sense? And LTE works sometimes, just has a hard time connecting most of the times. But when it has connected it works great.
When I first got my HTC LTE was working fine then it suddenly stopped. I called T-Mobile who was clueless, so I popped the sim back into my S7 Edge and Nexus 6P age LTE worked perfectly. I decided to try unlocking s-off etc to flash a more current firmware since mine was on a really old one. I flagged 1.30xx stock then LeeDroid rom being sure to not decrypt data during the process. LTE still won't won't, I'm only getting HSPA+ which sucks. I have another sim card I could activate, but I want to know if there's another way to fix this? My APN seems fine, as does the preferred radio mode. Any suggestions/additional troubleshooting that I can do before sending the phone back
Update:
Here are some videos I made showing the issue:
Part 1
Part 2
I will add another one using the stock ROM to further prove the issue exists on both the unlocked firmware, and T-Mobile one.
You root your phone, mess it up and then send it back? Kinda messed up.
Did you try flashing the latest modem?

No, I stated the issue was there before then. I only unlocked it and flashed updated firmware in an attempt to fix the issue which it didn't. Clearly we all need to read thoroughly before responding to an OP so we don't look arrogant in the end.
Now, on another note I mentioned this issue was already present from the moment I started using the phone 100% stock. It will sometimes still get LTE, but it only sticks for 10-30 seconds then drops to H/H+ immediately. My S7 Edge and Nexus 6P do not have this issue whatsoever therefore I'm certain something with the firmware is not right.

No, I can't get it to flash, but I'm going to try another method for updating it to that version
Mine has been extremely inconsistent in sticking to LTE. Sometimes I have to force it to LTE only and then when I switch back to GSM/WCDMA/LTE auto, it ****s the bed for a few minutes before correcting itself.

Did you try downloading the ruu.exe on the computer and then running it as administrator also make sure you have either changed your cid to the US unlocked one or to supercid I used the exe version of the ruu it went fine on my end I hope you get your situation worked out
I don't know your phone model, but since you are in the US. I would suggest you run US unlocked RUU for eliminating any software issues.
If you have an unlocked device, then you can simply download from @Behold's thread about us unlocked RUU.
If you have a T-mobile device, I would suggest you to get s-off and then run RUU.
Send back your modified phone is likely the least preferred option to do/recommend.

Yep, following the instructions to the t (so to speak), it ran fine, booted into whatever that weird screen is with the % on it then after about 15 seconds gave me the error

I did not boot into download mode. Left it on the home screen, Just made sure USB debugging was on. The RUU handled everything after that.
Quick update:
I changed my CID to 111111 and it flashed via the RUU .exe file (surprisingly). I still cannot get LTE other than a ran moment where it might connect for a second before dropping back to H+. I even made a new APN (copied from my S7 Edge) and it still won't get LTE. Could this be some bizarre sim issue despite it working on every other phone I own (4 other phones work fine with LTE and my sim)?

Have them re register the device on the network? The US unlocked base should work fine on TMOUS, I know as I have used it and both LTE, VoLTE, and WiFi calling fully work.

I have another sim, and I've reinserted it s few times now without success. I might call them and activate the other sim. It's just odd how it works flawlessly with LTE on every phone but this one.
Since there is no resource thread for this variant, I decided to create this one for the little community using this on XDA.
First of all, some warnings:
- Custom ROM and kernel do not work so do not attempt to try, it would just be a waste of time. Even if the ROM work, you will not have signal and there will be bug. So if you are not a ROM developer looking to support this variant, I suggest staying away.
- Debranding to unlocked/international variant is not possible. At best you will only soft brick, at worst you could brick your device.
- Since there are no RUU and none will be available in the near future, always have a stock back up at the ready.
- Root is only achievable with Sunshine through temproot and S-Off. So if you are not prepare to pay or for the risk, stay away as well.
Now, on to the main disk

In download mode using ADB issue the commands:

Fixed my 3g issue. But this was from a Different issue.
Won't hurt to try..
Thanks. I'll give that a shot
those ADB command will not work. says failed partition erase not supported
EDIT: nvm i ran it in the bootloader and they seemed to work, however i am still not receiving signal on my 10 with us unlocked. it seems the only way to receive the KDDI au signal at all is to flash verizon's radio.
au has a funky system authenticating the phone with an ID system which is embedded within the stock ROM. I don't know whether it is possible to have signal with an unlocked model. That's the only thing keeping me from flashing a custom ROM on the phone. Maybe some ROM developer could take a look into that?
I did notice that if u flash the Verizon radio, then install a ROM while choosing unlocked dev edition, as the provider, you get signal and bars, but this breaks my 5ghz wifi capability for some reason and I only received 3g at speeds of 1.5mpbs download. So not really worth it. Is there an ruu for the Japanese HTV32 out there that would flash in my 10?

OK, I install the RR Nougat 7.1.1 android version on my htc one m8. I have been using it for a while now without issues,
but just yesterday, my phone had low battery and it turn off.
After restarting the phone, could not connect it to my home country network.
I can't access the carrier settings menu as the 'com.android.phone has stopped' pops up.
I have most tuts on the forum but not much help. Even factory reset does not work.
After factory reset, Sprint apns settings are on the apn setup menu but after i delete them, still can't connect to my home country network carrier.
Please some help here guys.

Then this has nothing to do with APN, since voice service does not rely on APN (APN only applies to data cell service).
A few folks have had this issue of "no SIM" and no service after letting the battery die on the Sprint version M8. But I'm not sure what the solutions is. You may search around, as I know the issue has been posted a couple times recently. I suggested the Sprint RUU for one user. But it inexplicably caused the device to brick.

If s-off, try a lower level (such as kitkat 4.4.2 or 4.4.3) Sprint RUU and see if that helps.
You can only try this with s-off. If s-on, you can't "downgrade" (run older RUU then version presently on the phone) by RUU as it will fail the version check.
Also, don't flash any other carrier version RUU (only Sprint) as doing so with s-off may lead to permanent damage on a Sprint device due to incompatibility (even on a properly working Sprint M8).

The main issue, is that you bought the wrong version for your location. It's my strong opinion, that the Sprint version should never be bought by anyone except those using the US Sprint network. It's intended primarily for the Sprint CDMA network.

Yeah, your probably right, but I learnt that by flashing a new radio (radio frequency in HTC phones directly installs the network carrrier base band) can solve it but can't get the right radio image. Though am not a 100% sure but have tried some radio images but still no result.

If you are talking about radio images from other (non-Sprint) versions of the M8; radio from any other version is not compatible, meaning it won't work with the Sprint version, and can possibly lead to a permanent radio brick. This is for the same reason as I previously cautioned you not to run RUUs for another version M8.
If you are talking about flashing different radios specifically intended for the Sprint M8, that isn't any different from trying the various Sprint M8 RUUs (which install different radio image along with every other partition).
Hi all,
Would like to thank you in advance in taking your time in reading this post. Its my first time (and post) with the XDA forums. I have a few questions I am not sure if Im doing the correct thing so Im hoping for advice for the experts here in the forum to point me in the right direction.
Technical skills - never flashed a phone before but reading the step by step instructions available in the forums.
A few information with my phone to help with troubleshooting
- Purchased with no warranty overseas because they dont sell it here in the Philippines
- Phone came with the following specs
- Android 8 with Nov 1, 2018 patch
- unlock bootloader
- software channel - retcn
- Build number - OPXS27.109-52-10
- Baseband version - M8988_20207.117.02.41-01.01R NCD

1. 4G Network - not working at all on the local network. It seems to be able to go to 4G but cannot make outgoing or incoming phone calls/ text or mobile data.
- troubleshooted by resetting phone, changing apn with no luck. Changing it to 3G only seems to make the phone work to make voicecalls/text and mobile connection
2. Random apps crashing - namely - grab (like uber) and spotify.
- tried resetting the phone (and installed just grab app only after reset but still not working) and cleared partition cache boot mode but still no change.
Proposed solution
- installing a new stock rom - should fix the apps crashing issue and 4g issue
- installing custom rom like lineage (discarded this solution because it will disable audio mods) - i bought the moto mods JBL accessory.
questions:
1. Based on this thread - (https://forum.xda-developers.com/z2-force/how-to/how-to-return-to-stock-sprint-t3694783)
- I wish to install stock rom but Im not sure which rom to use. Do I use USC version based on the phones current build number? - OPXS27.109-52-10 or can I change to a different US carrier like verizon ?(related to next question)
2. Is there anyway to change/fix the carrier frequency so it will start accepting 4g locally here?
- will installing a stock rom with a different carrier (i.e. verizon), will that change baseband and accept other frequencies or will I brick my phone?
- Or hope the stock rom with a different patch will fix it? Ive read in forums it could just be the newer patches that giving me issues. The one available for USC is version OPXS27.109-40-7. Upon checking my local carrier and USC band frequencies, both have 5 band with 850ghz frequency available. So Im beginning to think it could be a software rather than carrier issue
3. Because the phone came with a unlocked bootloader, does that mean I will never receive OTA updates from the stock rom? I will have to manually update it when android 9 comes out?
4. software channel - retcn - does that have to do with anything with baseband or installing stock rom? Does this help in any trouble shooting? Ive seen a few threads in the forums with builds with specific software channel in other threads with specific models xt1789 - 02 or 03 or 06. I dont know if that affects stock roms?
-----------------------------------
Maybe it would also help to show my local 4g frequencies and band number
Smart Band is here below
Frequency Protocol Class Band Number
700MHz FDD-LTE/LTE-A 4G 28
850MHz FDD-LTE/LTE-A 4G 5
1800MHz FDD-LTE/LTE-A 4G 3
2100MHz FDD-LTE/LTE-A 4G 1
2300MHz TDD-LTE 4G 40
Sorry for some newb questions and I welcome any other methods of troubleshooting or suggestions you guys can give me. I feel installing stock rom USC carrier is the solution to the problem after all the research I have done, but would like confirmation first from the experts.

On mirror.lolinet.com, 109-52-10 belongs to Retail Apac. The newest rom was uploaded is 109-52-12.
If your unlocked bootloader phone is still running the stock firmware, it will be notified when OTA comes.
I'm using an ATT with carrier unlocked so everything is fine to me. With unlocked carrier, you can use any mobile network if the phone baseband supports.
According to basic theory, if the phone was unlocked bootloader, it can be flashed fw from other variants (but there will be problem for each variant situation). It seems none of us here has done this yet.
- Check your phone model, it's on the right of the charger port.
- Open Phone, and type: *#*#4636#*#*. Choose Phone info. Check the preferred network type. If you can receive sms but cannot send, just update your SMSC number.
Most problems can be solved by flashing the stock fw.
Good luck!!!
Thank you
I didn't even know that site until you pointed it out.
I would be definitely be using the APAC software and try and flash the stock rom. I hope it would work and if not I'll try and flashing the older patch version.
Thank you
Will update you hopefully in a week as soon as I fully understand the details of flashing.

Just giving people update incase anyone is interested. I decided to follow this guide Step E (reflashing back to stock). It worked perfectly for me.
https://forum.xda-developers.com/z2-force/how-to/guides-bootloader-twrp-custom-roms-root-t3805737
As you guys know the original Build number was OPXS27.109-52-10. It turns out that was meant for model XT1789-06. It wouldnt be a big deal except my model that arrived was for XT1789-05
Regardless I followed the instructions and installed the latest firmware for OPSC27.109-52-14 for XT1789-06 (https://mirrors.lolinet.com/firmware/moto/nash/official/RETAPAC/)
Installation went fine and all the apps crashing issues went away. However 4G still didnt work.
I decided to see if installation the latest build for XT1789-05 under the link below would help.
https://mirrors.lolinet.com/firmware/moto/nash/official/RETAIL/
It felt more stable, apps not crashing, moto mods still working, and I was able to get get 4G working for internet and sms however phonecalls (both outgoing and incoming) still didnt work. 3G seems to be still stable and working fine at the moment in the Philippines. (note: I have updated APN)
I have decided to leave it alone as I got half my problem sorted (apps crashing) and moto mods still working. Can live without 4G as its mostly connected to WIFI at home and occasionally going out. Crashing apps was more important win for me.
Maybe once Android 9 officially comes out for the phone, it may fix the issue.
I have explored the option of changing the radioband but I heard of nightmares for some users when they switched to USA. I dont know what will happen if I switch to Australia radioband. (i left it to automatic at this time).
Maybe if someone else found the solution, would be happy to try it out.
I'm sorry for you when you still have some problems. My friends mostly use Z2F form T-mobile and Sprint. ATT and Verizon are less. But they work well for all functions.
There's another way you can try. It's the method for dual sim. For eg, you've a Sprint one. You modded the hardware and the 2nd SIM slot is now available. But current Sprint fw only supports single SIM. You can download a dual sim fw, extract it and copy-replace the modem from Sprint fw to dual sim one (I dont remember exactly what modem should keep, sorry). Then, flash the combination fw and the phone runs with dual sim. You can try a stable system and retcn modem or vice versa.

Nothing to be sorry about, actually really grateful for your input.
Already had a big win by:
1. flashing for the first time ever to stock rom and not bricking my phone in the process
2. all apps are now working
3. moto mods are working
4. alternative solution to 4g issue is available
Just letting you know the my variant already is on dual sim, and I was pretty sure the modem was wiped and reinstalled when I reflashed back to stock. I did find another thread of similar issue. Only solution was really to either change to 3G or fix APN.

One user commented it could be a carrier issue. (see below)

Hello, guys.!
I've been following this inquiry very close and I've arrived into a very accurate conclusion:
1. This is not a device problem! Motorola devices are not the problem. I've found that Samsung and Huawei devices also have the same problems.
2. This is definitely about service provider network. In my investigation, AT&T is the one having this issue alone.
3. This issue happens only in certain Mexican areas. For example, in Monterey this happens. I went to Chihuahua and CD Juarez just last 3 days and I was able to use 4G and calls without problems.
4. Based on the idea that only happens in certain areas at certain networks, I can only concluded that happens to certain devices as well. Brands, perhaps, as unlocked iPhone does not present this issue.
------
It could be something to do with Volte 4G calls. It has been disabled for the Xforce 1789-05 european models.
I think waiting to Android 9 may be my best solution though I may start try to start troubleshooting and focusing on simcards to see if 4g will work with other carriers.
I've got an ATT Flipout. I could make call and sms normally. But the network could only rise to E+, cannot be up to 3G (several years ago). The problem was phone hardware. The baseband was only available for US.
Z2F was the flagship, so its modem supported many 4G band for other regions.
As you mentioned, I think you should find out what carrier's band would suit your Z2F. Luckily, all Z2F variants have our bands.
Good luck, guy! And hope you'll give us good news!
You have the (05) dual sim variant correct? You're also in the Philippines right? If you look at this link you'll see all the bands supported for your variant, also you can check carriers in your region to see what bands they are using.
If you look carriers in Philippines like Smart you can see what bands they use.
A comparable carrier is Claro in Brazil.
They use the same bands on a GSM network. I would assume that Retail firmware would open those bands, but I'm not 100% sure and maybe the firmware you flashed doesn't. I do see firmware for RETBR (retail Brazil) and I know that (05) variants are used there. So maybe flashing a retbr firmware will open the bands needed since Brazil and Philippines use some of the same bands. I'm not 100% sure on this, it's just my best guess. You're welcome to verify the info linked and do what you will. I'd think the worst case scenario would be borking your imei and having to blankflash, but those tools are around here as well and so long as you DO NOT relock your bootloader you'll find that it is pretty hard to actually brick this phone. That's the best I can come up with to help.
Thank you

Your correct, its the dual sim 05 variant. I flashed the retail and I do get LTE data. It just the LTE wont work on 4G. So I dont think its purely a band issue because based on your link I have 3 supported LTE bands with the smart network. Its possible its something to do with carrier communicating with the phone. (APN? Volte?)
Question: will flashing a retbr on a retcn cause issue? Does software channel matter? Maybe I can give it a go, but my wife (who i gave the phone to) has been pretty happy with it. I dont think she wants another wipe on her phone. (i think i already reformatted at least 5 times already)
Update
I found this thread with moto z play.
Maybe this will work? It a method to open all baseband channels.

I don't know about all that, looks like a recipe for trouble. Are you able to make or receive voice calls? FYI you can go to apn settings, click the 3-dot menu and reset to default. That should pull your apn info from your sim so you should be good to go apn wise.
There was an old method called RadioComm. It used to unlock carrier for Razr HD (and maybe others Motorola phones). But it is more danger than flashing fw.
On my Verizon phones, no APN profile was showed. But on ATT Z2F, APN was automatically set (and showed) for each carrier.
Inbound and outbound calls affected

Unfortunately still a no go.
I have reset the network settings and used default apn as per your suggestion. I even copied settings from another phone using same carrier and used different calling apps. It's weird but when at 4g
1. Text work
2. Data works
3. Inbound and outbound phone calls doesn't work
Swap to 3g everything works
I'm still trying to convince my wife if I should flash to retbr.

Well if everything works on 3g then it sounds like your bands are fine. Sounds more like a volte issue. 4g works, 3g works, calling works, it's just no calls when 4g is on. Are you using an old sim? Have you tried the sim in another phone to see if you experience the same problems with 4g? Some carriers use different sim for different services. What is your preferred network type set to? If it's exclusively LTE, try setting it to LTE/GSM. It sounds more like a sim issue, setting issue, or maybe a registration issue.

I dont think its a old sim issue because its only a year old. But I am getting another simcard from another local network to test it out.
Will update with details.
Hello harkoliar, it looks like both you and I share the exact problem. And best of all, or worst depending on how you view it, I am in Malaysia with the same problems, Grab keeps crashing, among other apps just failing to work period.
Software Channel reads RETCN. 05 phone running an 06 firmware.
I noticed you tried to flash a RETAIL firmware, may I know which was the file you used, was it OPXS27.109-34-21?
I don't have much problems with the connectivity and using 4G. Perhaps it may be a difference between telcos in Malaysian and the Philippines.
Oh... And I bought mine from Lazada, where did you get yours. LOL

Same Lazada. Lol. We must have gotten from the same supplier.
Your right, I installed OPXS27.109-34-21. Worked like a charm after that. Please follow the steps provided in the guide - Step E.

note: be mindful just what version of android your using. Im assuming its also android 8 like mine. If its currently Android 7, i heard its best to install the android 7 rom first then upgrade to 8. You can tell by the versions.
Another user also having the same problems and reinstalled the latest Retail ROM for XT1789-05 - latest version, worked for him as well

Was your seller named Aukey? I left them a stinker of a review, lol.
Thank you so much for your experience and detailed breakdown of what you did to get right with your, now, wife's phone. :laugh::fingers-crossed::victory:
