Hi, I recently replaced a non functioning 9T Pro mainboard with a replacement which is working well in all aspects except SIM registration (the main phone function ...!) - looking through the details it looks like it's a K20 Pro from India (from Alibaba, origin not advertised) and the ROM is Indian. The SIM doesn't seem to be able to register on an Irish network. My question is whether the radio restriction is a hardware issue or is software fixable - I'd be grateful for some advice before trying to unlock the bootloader install an EU ROM, as it's difficult to get the unlock from Xiaomi without a functioning SIM for SMS OTC etc. I've tested the SIM in other phones and it registers on the network okay. I've also tried a different (known working) SIM in the problem phone, without success, which is leading me to think the issue is isolated to the phone rather than a SIM issue. It would be really helpful if I could find out whether going dow the flashing route it worthwhile or a dead-end. I've spent many hours flashing various phones over the years, trying to match ROMs etc., and know what a rabbit-hole it can be.

Hi, any takers on this query ;-) - I'd love to hear from any tinkerers who could give me a steer on whether I'm wasting my time going down the unlock / flash with correct regional variant, or if I should just write off the board / phone as being only useful for wifi rather than sim network. If someone who has treaded this path before with some success could let me know I'd be much more enthusiastic about dropping a few hours on it - I've spent many hours on flashing various devices before, and usually have less hair to show for it before I'm successful. Even if it means (as I've read in a few posts around here) that if I lock the device again on a rom that's not regionally compatible I'd be inheriting a paperweight(!), it would be nice to know that in a controlled environment the sim would work. Would be a shame really to nothing with the board as I (stupidly!) splashed out on a 8GB 256GB replacement and (surprisingly) any queries to the vendor on AliExpress have fallen on deaf ears surprisingly ...

Unlocking Bootloader usually requires to wait 7 days and during that time phone must have a proper SIM card, attched to the Mobile network.
Not sure how would you do that in your case?!
Anyway, start waiting for those 7 days, better earlier than later. If you change your mind, you simply don't unlock the Bootloader upon the 7 days of waiting pass

Yes, good idea, thanks for the suggestion. I'll see if I can kick that off / whether the sim registration issue blocks me. If anyone else has been able to verify that flashing can help regional issue with SIM registration and support bands that would be great too! Thanks.

Hey there guys, I've been searching the forums for the past couple hours and I can't really find what I'm looking for, mostly just references to Android devices. I have a Lumia 520 that I am using on the Straight Talk service, and I cannot get the internet sharing capability to work. I have seen tutorials on youtube and in other places (besides these forums) and none of those methods have worked for me. Could anyone give me any insight into what I might be able to do to get this feature working? Thank you.
Obvious first question: what happens when you try to use it?

It sits there for about a minute or two and says 'Connecting....."
and then eventually I get this screen.
Wow, I have never seen or heard of that error before (there are a few common ones; that's not among them in my experience). That sucks.
Best guess: is the 520 branded to a particular carrier? You might want to try flashing an unbranded ROM (or a Straight Talk one, if such a thing exists) to the phone, just in case it's some carrier-specific configuration BS.
Otherwise... there's hacks that can be done with registry editing, and it *might* be possible to apply them to your phone, but I wouldn't count on it.

Yeah I didn't see the error mentioned on any of the threads I was looking at. To be honest I am not a developer and half the stuff people say on this website I really don't understand. I was looking at your interop unlock thread and I should have worn a bib to catch the drool. I had no idea what you guys were even talking about half the time. The only thing I could gather from that thread was that the interop unlock doesn't work on any Nokia Lumia anyway regardless of branding. I bought my Lumia 520 as an AT&T gophone, but was able to put a Straight Talk SIM in it with no issues. So I do know that it works on different carriers, but the code someone had me put into my phone showed a locked icon which I guess means that it's sim locked or something? Bah. I'm confused.
It's *probably* not SIM-locked (or at least not anymore), since you aren't using it with the original carrier, but that's not the problem anyhow; SIM-unlocks don't remove carrier customization of features like Internet sharing. If it was something like the phone telling you to contact your carrier to have tethering added to your account (when your carrier already allows it), that would probably be a carrier branding issue. Similarly, if the phone just lied and said you had no data connection to share (when you totally did), that's probably the phone trying to use a carrier-specific tethering feature instead of doing it generically. Yours *could* be another example of the same kind of thing - you might try flashing an unbranded ROM, I guess - but I really don't know.
There are other options. For proxy-aware apps (web browsers for sure, many other things as well), you can run an app that sets up a proxy server on your phone. Tether-X is one such example; I've successfully used it before.
Hello.
A friend of mine worked at a company that closed last week, and they had some demo-based Galaxy Note 8 phone that were unused. So I took one of them, and I'm now trying to make it work with my SIM Card.
I don't looks like it recognize it, phone network isn't available, IMEI is unknown, and Service Menu (that i tried to turn radio on) is blank (I accessed it trough *#0011#). I passed like 5 hours googling, but since it seems to be a very specific issue (the phone was probably locked for Demo puprposes.). I tried a custom ROM, I rooted the phone, but nothing changed.
I'm sorry if my question isn't that accurate and descriptive, got a real headache trying to find an issue tonight. Feel free to ask for precisions.
Thanks for helping, as always.
Demo units will not function as normal legally acquired devices do, no solution will work, get a really working device, xdemo units are exactly that, just for show
Changing motherboard won't do the trick ?
It will, but I would rather get a never opened device, besides, a motherboard will not be cheap
This is the phone: https://shop.simplemobile.com/shop/en/simplemobile/phones/sm-moto-e5
1. Is there a way to root it?
2. Where can I find the stock firmware for it?
I can not get anything on the internet about this model
I have done quite a bit of searching online and prodding at this phone in various ways and have found no way to root it unlock it or even get third party manual camera controls.
It appears to be a Tracphone remarketed E5 with a lower resolution camera and a few other locked features (mostly software things). I can only picture that a lot of our problems rooting this phone and getting support (specifically in English) have to do with the fact that "technically" the US isn't even supposed to have an E5, but the E5 play and plus. Which is why we have a Nora Baseband, 8MP camera, Android 8.1, etc. All the features (That may produce or interact with radio emissions) are mismatched to match other "authorized devices".
There is a thread here that lists all the Nora devices as Plus models but "1920" from the same master list is a play model. This model is also listed only with non-contract carriers (appears to be mostly CDMA) woth remarlably little information on it and has a small customer base since most just get the plus.
Even Motorola won't touch it with unlock codes and such like they (supposedly) will the plus model. So I don't think this specific model will get much attention anytine soon, or possibly ever. But again, this is all "from my understanding". So I could definitely be completely wrong. There are guys here who know substantially more than I do on the matter.
This of course isn't to say I havn't enjoyed the only Snapdragon 400 series phone not to be completely piled with non-removable handcuffing UI clutter.
Same question about NETWORK UNLOCK.
So, first to correct myself. This model is now being used for other non-contract carriers, too.
Second, referring to the carrier unlock. That depends on exactly who your carrier is. Some are known for unlocking the day you pay for it in full, others are known to never unlock them even when you meet the requirements by delaying giving codes, rejecting authorization, or removing the ability to submit the code in the phone's firmware. However, most carriers fall in the middle and usually require some number of months of operation of the device on their network and it be paid in full etc. etc.
So, check with your carrier and if they won't unlock it you'll have to meet the requirements or wait for someone to come up with new methods to modify the partitions on the device and/or find a way to unlock the bootloader. Some people (once boot unlocked) have had success with flashing different carrier firmware to gain GSM sim unlock and use with other networks. I did it with an old Samsung ON5 once but our devices don't have near the unlock, root, and rom support lol.
Good Luck though! I hope you figure it out if I don't.
Hi There
Hopefully some insight can be shed on this topic, it would be greatly appreciated.
I've read that all you need to do is use the device in the region of purchase for 5-10 mins of local calls & then the region lock is unlocked to any world wide sim.
- is this still the case with Samsung devices?
- lets say once the device is unlocked (in country of origin) but reset a few months later in another country other than it was bought in, will the region lock be back?
Thanks

so, the question youre asking can be answered in several ways. Firstly, the locks placed on the phones are placed by the carrier, so if your phone is truly unlocked, itll never lock on to a service provider permanently. The process you describe about using it for local calls for a few min to have it grab your carrier is CSC related and more applies to whether you can use SPay and SHealth or not. There are also subsidy locks that make carrier switching impossible without an unlock. These subsidy locks can be in the firmware or even an app that was granted root permissions making it impossible to remove on snapdragon devices outside of Odin.
I guess, what issues are you trying to avoid?

Firstly thanks for taking the time to respond. ?
So I'm not technical at these things but here's a quick background on my query.
A friend purchased a Samsung from an Asian country now while there & the box said specifically that it is made for use in that region and their sim. He's using it but won't know if it will work here till he returns. He is able to get one for me as it's much cheaper there, hence the research on the topic.
Through my search I've seen on Samsung forums people buying phones from difference regions with some able to successfully use it in their country & others not (comments vary on reasoning as to why but the use of that country local SIM seems common)
When he queried the sticker they said to just follow that calling process (I'm presuming now this is the carrier lock) However I'm not sure if there are carrier locks on the device as through my search, that country normally doesn't practice carrier locks (Service Provider) as the US or Europe does as devices are sold at any shop in Asia. So it's a bit confusing..
From your knowledge, let's say he activates & uses it for a few minutes. When he returns & I reset the device, will the lock revert back for that region or will be opened for any sim? And something that just came to mind, as the Samsung devices are regional, will this affect how updates come through or will it be based on that regional timetable for updates?
Thanks again

terrible questions.. i tell ya what..... TOTALLY KIDDING!!
actually very solid questions and its also great to hear people doing this kind of research prior to pulling the trigger. I commend you
Anywho, lets see.
1: What Asian country? Yes, it matters. Or if you can get the model number from the download mode screen, that would be helpful too. If you dont know how to get to the DL mode, power the phone off, hold down the volume down button along with power and itll boot to a warning screen that will say volume up to continue to download mode or volume down to reboot normally. If you cant get that kind of access to the phone (or your friend rather) then its a crap shoot as many phones being offered up like this have been found to be non-us versions or even worse, utter fakes. Buyer beware if you cant get to download mode to at least check that too. Download mode is the hardest part to fake, fwiw
2: Galaxy S devices come in 2 flavors, Snapdragon and Exynos. Well, 3 i guess, the 3rd being fake. Snapdragons are the only ones that can work on CDMA carriers such as Sprint and VZW, Exynos phones work on GSM only. SD phones can also use GSM services, but the Exynos equipped phones are GSM only. SD are not rootable, Exynos are.
3: The part about your friend using it with their SIM and having problems strictly due to that. No. So long as its a legit USA model with no financial locks on it etc etc, you will be just fine. You might have to flash a CSC file in download mode or perhaps even the entire firmware (doubt youd need to do that last part), but if its an unlocked SnapDragon model built for the US market, then youre good to go.
4: make sure it doesnt have a FRP lock enabled. As long as your friend can boot it up and get past the login screen, you should be fine.
5: The last bit about the SIM again, as long as its a legit G973U with no locks and FRP inst on, you should be good to use it on any USA carrier no matter where it was initially used.
6: updates are issues out in order of IMEI batches. Being physically in a country outside of the one that the firmware is for can and often does impede updates, but thats not a worry as updates can be easily flashed manually and once the phone is on the correct CSC and physically in the right country, then updates will go on as normal.
7: youre welcome

Firstly apologies for the long delay in response, just been crazily busy and was doing research on what you said soon I am up to scratch to what you said.
1. It is from India, and yes I am aware of fakes so any purchases will be from reputable seller's. I'll have to do some research on that because I'm sure the different Samsung models will have their own codes.
2. I believe for that region they get Exynos variants.
3. From looking at some of the Samsung models online I see the product code ends with "INS" which I'm pretty sure relates to India and that country only so probably I will have to follow the DL mode you explained for my region in changing the CSC
4. I never knew about this.. How does one make sure its not enabled? Is this in the process that relates to no.3 during the CSC change?
5. Not from the US but good to know lol
6. Perfect lol
7. Thanks again, appreciate it :good::good:

2. I believe for that region they get Exynos variants. i believe so too. Id just get pretty much any F variant of the phone model you want and youll likely be able to get it working from there
3. From looking at some of the Samsung models online I see the product code ends with "INS" which I'm pretty sure relates to India and that country only so probably I will have to follow the DL mode you explained for my region in changing the CSC. just stick with the F models, you can flash whatever carrier stuff you need after you have it in hand
4. I never knew about this.. How does one make sure its not enabled? Is this in the process that relates to no.3 during the CSC change? Itll show you this in the download mode screen. Itll say FRP: on or FRP: OFF
5. Not from the US but good to know lol

always glad to help bro!
Good afternoon fellows,
I seek your help for the next issue. Long story short, a partner from my work asked me if i could help her with her Redmi 8 (she told me that his son found it somewhere on the street), the device was locked by the mi account and frp from google. Looking for tutorials and such i finally could by pass both of them but i think i messed up something.
now the phone opens normally but the wifi won't connect and the sim card is in "just for emergency calls". I have tried to install a new rom but there is no way to flash it as (i think) is bootloader locked.
Is there a way to install a rom (i dont care if its the latest or newest) to make it usable at minimun?
thx before hand.
honesty id suggest to not go further. modern phones are pretty resilient nowadays and when you successfully bypassed the lock, the phones definitely blacklisted by xiaomi. what they shouldve done is tried their luck and go to a xiaomi service center instead. network and WIFI locking is usually a false indication, sometimes they can get within range (of a free WIFI or network restrictions) and track through GPS. it was probably locked in the beginning because the owner ordered xiaomi/google to wipe the phone. even with legit methods (buying|giving used ETC) a millenialist without any knowledge how internet accounts work can get blocked often.
some 'unofficial' tools are malicious, ive reversed engineered a few in the past for the fun of it and found 'sketchy' stuff behind the scenes. i havent tried any xiaomi tools so i cant call out theit methods.
and from a parents POV, theyre definitely in the wrong. what if the old owner successfully tracked the phone back to you guys?
-_-
