I just successfully rooted my Samsung Galaxy Note 2 using Odin and CWM Recovery.
This is exactly what I did:
- D/L Odin 3.04 and "cwm6-root-note2.tar" and saved them to my Desktop
- Extracted Odin and started the program
- Set my Note 2 to USB Debugging
- Restarted the Note 2 in "Downloading Mode" by holding down Volume Down, Home & Power buttons simultaneously
- Connected usb cord to my phone and computer
- Confirmed that Odin registered connection of my phone correctly on COM port
- Went to PDA, then selected "cwm6-root-note2.tar"
- Then I selected start, or root or whatever starts the process. And voila! Rooted with CWM & SuperUser App.
However, I might be returning the phone so I now need to know how to reverse that process and UNROOT my phone. Can someone please help walk me through that process? Do I need to obtain more files that were overwritten or deleted when I rooted?
Also, I thought, perhaps, I could unroot using the SuperUser app so I chose the option that said something like "Unroot.... etc." All it did, however, was get rid of Super User because when I restart my phone in recovery mode, it still boots CWM-based Recovery v6.0.1.4
Any assistance would be GREATLY appreciated.

Thank you for your assistance. Which link do I download though? Are they all the same? Or do I need to find the link with the country I bought the phone in? If so, I didn't see Korea on that list at all.
Also, when I do this, will the counter be reset to zero?
Thanks again for your help.

Hi,
So you rooted a LTE version, can I ask which version did you have (SHV-E250S / SHV-E250K / SHV-E250L)?
Is it meaning the rooting process of LTE version is same as the non LTE (3G?) Note II?
Also, what is the reason of returning the phone? Did you find something not good with LTE?
Thank you.

I rooted a SHV-E250L. The process went very smoothly. Especially considering I'd never rooted a phone before. So, from my experience, it seems to be the same process but don't take my word for it.
The phone is awesome - no problems at all. It was just very expensive and I was having a little buyer's remorse. I'm over it now. I was also concerned about not being able to use it in the US when I move back, which I am still unsure about. I have asked a few developers on here but haven't heard back yet. If possible, I'd like to flash a US ROM on the phone so that I can use it on the networks there and access the unrestricted Google Play Store... so, we'll see.
Hope that helps.

I dont think these will work with your phone. These are for rhe N7100. Going by your recent posts, it looks like you have a different model.

Brian,
I am living in Korea as well and I have a lot of experience with the Korean smart phones.
To answer some of your questions, you can use them in the states with either a Stateside SIM (assuming your phone is unlocked, you can get it unlocked from the store if you're going to be traveling) or a Korean SIM (obvious roaming charges). I don't think the LTE bands are the same in SK and the US, therefore you wouldn't be able to use the LTE.
In my experience (with my SGS1) you won't be able to flash a US or Int'l ROM on your Korean model. The internals might be closer than the SGS1 and it's variants were but I wouldn't do it unless you have the Note2 Korean ROM ready to flash back with Odin in the event it won't boot.
You can get unrestricted Play Store access now. You need to download MarketAccess. Google it. it Allows you to basically tell the phone what network it thinks it's on.
In the event you ever need to unroot your phone, you just need to use Odin to flash the official firmware.
If you need anything else, let me know...

Most likely Tegrak will have a kernel for this device before too long. You would then be able to use the Odin software to root the phone. The process is the same for both.

Thank you so much for the answers. I really appreciate it. So, you're saying for sure I will not be able to use this phone's LTE capabilities in the US on any network? If so, that's a huge game changer for me... I wonder what LG U+'s return policy is... I know I can just transfer the phone to someone else here in Korea when I leave and pick up a Note 2 in the states when I go back but I feel like I'd be losing a lot of money since the cost of the phone is spread out amongst the monthly payments here in Korea. Are there any phones that will work work both on SK LTE and US LTE?
Regarding un-rooting my phone, don't I need to get a hold on the official firmware before I can flash it with Odin? Or is it stored somewhere on my phone? All the official firmwares I've seen on XDA are for the N7100 not the N7105. Any suggestions?
Thank you, again, for all your support. You rock!

No problem, glad to help.
I am also looking for the firmware online. I haven't found it yet. PM me your email and when I find it, I'll send it over to you.
All info I have read says LTE is different. The 3G would still work just no LTE.
Idk what LG's policy is, but you could take it to Samsung a/s in the electronics market to revert it if needed.
Good luck. I might know someone who could take the phone of your hands next year if you want to go that route.

Good info here. But what about his flash counter? Will that be reset to zero by flashing stock from via Odin?

SHV-E250S problem.
Hello SHV-E250S/K/L users.
Does anyone know where I can download an official factory stock ROM for my SHV-E250S ?
I have an IMEI missing issue, and EFS file deleted issue. After wich i have a black notice on the screen and no boot logo or turn of logo, it just switches straight away after pressing the button.
No network or IMEI(((
I just came back from the Samsung official service center, and guess what, they can`t help me. They say i need to flash an original factory rom, i even brought them the two roms i downloaded from the: www.sammobile.com/firmware/?page=3&model=SHV-E250S&pcode=0&os=1&type=1#firmware
And they said that these are not official factory roms, that they are custom, all thaw when i flash with one them, and go to recovery mode, my current binary changes to official. Don’t know why but everything else stays the same:
ODIN MODE
PRODUCT NAME: SHV-E250S
CUSTOM BINARY DOWNLOAD: Yes (37 counts)
CURENT BINARY: Official
SYSTEM STATUS: Custom
DON`T KNOW HOW TO FIX, AND WHERE TO GET FACTORY ROM((((
Would appreciate any help!

And other users as well please, If someone has SHV-E250S, could you please share your pit file with me?
For me to try and flash my device with your pit.file in order to recover my partitions and BINARY TYPE, when i open my pit file in pit magic, binary type is unknown((( Want to flash with official rom and your correct pitfile.
Thank you.
*YOU MUST BE ROOTED AND USING AN AOSP ROM*
CM11/PA/PAC-MAN/LIQUID SMOOTH will do the trick.
*Pop in a US Sim card (Tmobile, AT&T, H20, Family Mobile etc.)
*Open dialer app
*Dial *#*#4636#*#*
*Choose Phone Information
*Scroll down until you see the Network Type
*Click the box and choose GSM ONLY.!
And that's it folks. You will see the service bars appear after about 2-3 seconds. Set your apns if not already set and enjoy GSM carriers on your Sprint G2.!

I didn't think it'd work at first, because of all the other unlocking methods out there, like changing carrier files, unlock codes, T-Mobile ROMs, but I can happily say it works I tried it with an old Metro pcs sim I had. I got the "No service" signal because it isn't activated, but at least its detecting the sim card Thanks for the info! Oh, & I was using the CloudyG3 ROM version 1.2 & it still worked

No LTE, since the needed bands are missing from the phone. But yes, 4G (HSPA+). Several weeks now on Cloudyfa G3 ROM v1.2. Pick "WCDMA preferred" in the mobile network settings, and choose the T-Mobile APN without LTE, although the LTE one seems to work OK as well. If you have any issues kick-starting the GSM radio you can download Radio Switcher from the Play Store.
The only issue is that some of the T-Mobile towers haven't yet been "refarmed" or "unlocked", so on this device in that case you would only get 2G data. For example at home I get HSPA+, but at work only Edge/2G. Hopefully that will change in the coming weeks to months as T-Mobile continues to upgrade its towers. The same issue applies to a Sprint iPhone 4S and Republic Wireless Moto X that I unlocked and am running on T-Mobile as well.
Guys I'm new to this rom update business, I mean I have done plenty of windows phones but none of the newer androids.
I have an LG G2 32GB Sprint (bad esn), purchased from ebay, but I'm in the UK.
Any idea of how to get it working with the UK?
Links and instructions would be most helpful

Sorry cannot provide links I m on the go. First you need to check if you are on latest ota which is zvd. If you're on zvc root with latest iroot. If on zvd search the forum there is an apk which you just install to your phone and run it (called towelroot). It roots even without reboot. Then search the forum for ls980 permanent unlock and follow the guide. Just use any root explorer to copy the files, restart and you are unlocked but with no speed data icons on status bar. The other way, is after rooting, install autorec (search for it - it's tricky, you might brick). Autorec is needed to install custom recovery. Then just pick a rom from cloudifa (g3 port is great with no bugs). His roms are made for gsm and you will be already unlocked. If you prefer aosp based, only one that worked for me after changing some settings and restarting is Omni. Couldn't make carbon (discontinued), vanir and mahdi to work. They didn't even recognize that a sim was inserted. Before flashing a custom rom, make a full backup via custom recovery and make sure you get familiar with how you enter recovery and download mode with hardware key combination. Keep in mind there is always a chance to brick and then you will have to enter download mode and flash back to stock with lg tool. If you are confused ask any questions and I ll try to help when I get home on my pc. Did all above a week ago and ended with cloudifa g3 port and is working great so far (I'm in Greece).

Thanks very much for your help and advice, I can get as far as unlocking the device and it all works However, how do you enable data? If I can enable the data then I'll keep the normal ROM and use it
Also after installing a custom recovery, the autorec works great and I can understand the concept of it, but then when I flash with the cloudifa g3_1.2 it flashes but when the phone restarts it gets stuck (first time at 49%, then had to reflash using stock via LGFlashTool, then second time at the LG logo) so I have to go back to the stock rom, root it, unlock it and back to square one. Unsure what to do next?

In order to enable data you have to check your apn settings. If there are no settings, try to set it manually (Google your carrier's apn settings). When you are done and you get data to work try a reboot to see if they stick. I think in the permanent unlock thread you can edit this file with the apn settings and add your carrier's ones. Also delete those 2 files so you can automatically have data after each reboot.
Now I didn't really understand what went wrong while trying to flash g3 port. Have you flashed the appropriate baseband? It's very important in order to boot. It's mentioned and there is a link as well in the op of g3 thread.

Bought this phone on eBay few days ago and I started checking around about how to unlock it(though it'd be simple as any other phones, but I guess I was wrong). Found few threads talking about how to unlock it for US GSM carriers but barely find any information about using it in Canada.
Looking to root\use a custom rom and read that the CloudG3 rom will actually GSM unlock the phone,but will it work as well for Canada(will be used on Telus network)
Thanks.
As long as the band's are supported it should work.

There's a Rom on xda that converts the spring variant to the T-Mobile variant by flashing the Rom. It's basically a T-Mobile variant g2 cm11 Rom but with a Sprint boot.img and a few other Sprint files to make it boot. But if I'm not mistaken it has the T-Mobile radios in it. That should get you their full network experience.

Think this thread might be dead but if I get a reply it'd be great. Will the OP method work on the latest CM12 nightly? Or does AOSP here refer to only the CM11 variant?
Currently not the Device Maintainer for the G2. I'm working with the G Flex community now. I'm pretty sure there's a CM12 nightly already released. Updates will be posted in whatever thread you originally downloaded it from

Hello!
I am currently with Telus and have just unlocked my S3 after purchasing the unlock code. If the phone is on the stock Samsung ROM, I can insert a Wind or Rogers SIM and it works fine. However, on the CM-12.1-20150519-NIGHTLY-d2att ROM, it will _not_ connect to any other network. I tried manually searching for network but it fails with a message like Unable to search networks.
I'm not sure why this is happening or how to troubleshoot this. I would prefer to stick with a Lollipop ROM for now.
The CM d2att wikki page does say that since CM11, we should be using the d2lte version for this phone. So should I be installing the d2lte ROM instead?
Thank you

I installed cm-11-20141112-SNAPSHOT-M12-d2lte and unfortunately you were right. I still can't connect to WIND.
I have another fully stock S3 and I ran the Samsung Phone Info app on both to compare. Under the Firmware tab, the PDA version and CSC version is empty on the phone running CM11. Please see screenshots attached which shows this.
Also, I ran the SIM Toolkit app, tapped Manager Services and it gave me a ME returned a temporary error.
Any help would be greatly appreciated to troubleshoot this. To me it does not make any sense that on a unlocked phone, with stock or custom ROM, Telus (this phone was locked to Telus originally) connects just fine. With stock ROM, I can connect to WIND and Rogers but cannot connect to either when running a custom ROM
aaaaaahhhh !!!! @audit13 , hhhhheeeellllpppp !! (please) :what:
"all i can really do , is stay out of my own way and let the will of heaven be done"
The case is missing because there is no carrier customization on a custom rom.
It was my understanding that wind uses aws which the s3 does not natively support although there are hacks to enable these frequencies.
I am not sure how it could connect to wind on a stock rom.

Hello Mr audit13! It's not just that I can't connect to WIND when runnning CM11, I also can't connect to Rogers. Does that still mean there is a frequency issue?
Edit: Looking at WINDs website: (http://www.windmobile.ca/my-wind/faq/devices)
"The WIND Mobile network uses a frequency called AWS, with bands 1700/2100 MHz.(Phones compatible with the U.S. T-Mobile network often work with WIND)"
When you load cm11 or cm12, does your phone show the correct imei?
Which stock rom will connect to wind and Rogers?
Which baseband are you using with cm11 and cm12?
Crazy autocorrect on my iPad changed csc to case
autocorrect OFF. lol. ty for coming to help. :thumbup:
"all i can really do , is stay out of my own way and let the will of heaven be done"
I just did a sanity check. Installed stock ROM and put the WIND SIM in it. It wouldn't connect automatically so I searched for network and it does not show WIND in that list. It only shows WIND Away which is Rogers or Telus I think.
@audit13, you were correct. This phone will not connect to WIND.
I guess I'll just buy a new phone. Nexus 6, here I come!
Anyone in the market for 2 S3's? One is unlocked.
The i747m can connect to wind with a software hack; however, the hack must be applied every time you reboot the phone.
How much for the s3? It's still a great phone.

I see a couple of S3 on sale on Kijiji for 180. Both phones are in pretty good condition. So I am hoping 180 for the unlocked and 160 for the locked one.
Just wanted to let you know that I bought a refurb s3 from koodo for 90 and a refurb note 2 for 180 from koodo. Both come with a 1 year Samsung warranty. They both looked new. You can't find the phones on their website, you need to call the store and ask for stock. I got these phones with no contract, unlocked them via code, and are being used on Rogers and bell.
Oh, hmm. Well, I guess I will try my luck on Kjiji.
Thanks for all your help.
I've checked out kijiji and craigslist and the prices are similar to your asking price. Many people don't know that Koodo sells refurb phones and it was just a matter if luck for me when I got the phones. They weren't even for me! I've been using an old HTC One X from Rogers for the past 8 months
After reading news that Factory Reset leaves most of the data on the phone (research done at Cambridge University), I am very very hesitant to sell my phones now.

That only applies to the ROMs up to 4.3. Why not just flash 4.4.2 a few times, encrypt, decrypt, re-flash? I'm not positive these steps will make it better but it's the only thing I know of.
Have a very weird problem, and think it is because of any app...
I use a galaxy tab s4 lte as a phone, it is a fully functional phone oversized... it is great, and im using tablets as phone 3 or 4 years ago... first was galaxy tab s2 lte, then s3, and now s4
S2 worked great... S3 worked great but from march of this year, randomly phone disconects fron network just to receive calls.... sms, 4g and wifi always work, but canr receive calls till i make a call... it is like it disconnects from network... i notice that, because i have (from the times of s2) my phone forwarding calls to my wife's phone when my phone is turned off or im in a plane for example...
But with tab s3, from march, i was in home with my wife and someone that call me ringed directly to my wife phone... as if my phone was turned off...a lot of times saw that... but when i place a call... it start receiving calls again...
Went to tmobile, changed the sim and same problem...
Bought a new S4 lte ($1000) and from the day 1 same problem...
Any help? Im pretty sure it could be any app... but dont know where to start
Factory reset, then install your apps, one at the time until it happens again. It's long process but unless someone came across it it's the only way to find out which app causes it. Perhaps not the only way. Have you tried to replicate it? Reboot your tablet, then ring it to check if it receives it. If not, you can uninstall one app, reboot, call, uninstall , repeat until you find which app it is. It's likely quicker this way but you need to be able to replicate it.
Most likely is the VoLTE is not set up right. And sounds like fallback to 3G for voice is not happening. Try locking it on to 3G and leave it in standby. Check whether inbound calls are coming through when you are camped on 3G.
It is possible to edit your CSC file to get it working properly. but you'll need to know all the correct fields to change and will require you to root, install custom recovery etc.
I haven't thought about that. Try that first. I mean locking to 3G.

Sounds good... but would hate if this was the problem, dont want to root phone... anyway... s3 was working ok till march... one year worked great! Because of that i think it can be a setting or app... there is any way yo change volte? I have seen something like that in any menu but cant find now
Seeing about volte... i remember on s2, and on s3 im not quiete sure, the hd call icon, related to volte, bit now have not that option in phone app settings
Thanks
I don't think the tabs4 t835n makes calls over lte, only 3g as per the specs on the samsung site. Mine always reverts to 3g when making voice calls. It still sounds great but this is the way it makes or receives calls.
Continuous Talk Time (3G WCDMA) (Hours)
Up to 50
That being said, it would be great to find out if it is capable and since there is root now, take the settings from the note9 and push it to the tabs4 T835n.
Have you tried if it receives calls after reboot?

Friend... switching to 3g works great... this problem is on lte... it is possible to edit or flash csc without rooting? Would be possible to edit with s9 parameters? I mean, dont know if it has 10 lines of code or 10000! Just asking
Would like to fix it without rooting

I'm not sure it's possible without root access. You could try extracting the correct csc file for s9 and flash it via ODIN.
If you have root access you can peruse your csc file using this app:

Maybe you can ask your carrier to disable VoLTE for your account?
You will be trying at your own risk when you try to flash alternate CSC, remember you can always flash back to original.
You could also try flashing a complete firmware from a different country, check firmware available on Sammobile, search by your model code. TAB s4

3 Great ideas!... ask your carrier seem to be the best if they cooperate... flash csc is the second best because have not to reset phone.... and flashing a complete firmware from a different country is a great idea too but have to reinstall everything...
I think this was what happened with my S3... everything worked fine till i flashed a complete firmware from a different country when oreo update came...

F***... there is only one firmware for the T835N (i own a T835N)on Sammobile but 3 for T835C... will download all 4 firmwares and try to figure out if i can get the CSC file form a T835C...
PD: Do you know what is the difference between T835N and T835C?
Thanks again friend

Its me again friend... sorry for bothering you so much!
Look... here is the think...
I have downloaded two full firmwares...
the T835NKOU1ARGH_T835NKOO1ARGH_KOO for the T835N (the only firmware sammobile has for T835N)
the T835CZHU1ARH3_T835CTGY1ARH3_TGY.zip for the T835C (the latest firmware sammobile has for T835N)
When i extracted the CSC from that two firmwares i saw they are differents sizes! T835C is more than double than T835N...
Look at the picture attached...
T835N CSC File
CSC_OMC_KOO_T835NKOO1ARGH_CL13953229_QB19044239_REV00_user_low_ship_MULTI_CERT.tar.md5
47MB
T835C CSC File
CSC_OMC_TGY_T835CTGY1ARH3_CL14074605_QB19357398_REV00_user_low_ship_MULTI_CERT.tar.md5
112MB
What do you think about this? would be safe to flash a file, from other device with double the size...
It is the only thing i can do (talking about flashing other CSC) because on Sammobile there is only one complete firmware for the T835N... is not like other phones that you can choose country... the only country is korea
Thanks in advance....

I believe if you flash only the HOME_CSC it will preserve your data.
You don't need root
First up though, I would strongly recommend you try to back up your data using Samsung Smartswitch (back up to SD card). And try to back up to Samsung Cloud (not sure if this still is a thing). So you can restore when things go pear shaped
I believe the chances of getting VoLTE working faultlessly on your Korean tab are pretty close to 0. But if that's what you want, I would first try flashing a known working CSC from a device with same android version on YOUR carrier (Note 9 maybe?). This is unlikely to work, I think Samsung has been encrypting CSC files recently. You may need to flash Korean firmware at this point.
Secondly, I'd try flashing an alternate csc_home package from another country. Try the one you've downloaded. If you search T835 on sammobile there are many countries listed. I'd try XSA Australia if the first one doesn't do what you want.
You're on your own my friend.
If all this is getting too hard, just leave your tab locked to 3g in it's current state.

Again friend thanks for your help is really helpfull
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
Issue:
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.
Regards
Rj
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

Just finished flashing! So far so good, installing apps as we speak! Super excited!
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:
Different seller but same source most likely

Happy to help and hopefully that did fix all your app problems. :good:
Still credits and thanks to the actual guys who did the guide.
