Phone has no service on Band 2 (PCS/WCDMA 1900)

I haven't tried to root this handset yet. This is my #2 handset. The 1st the screen broke so I used my insurance to get another. I work with phones all day long including iPhones, other T-Mobile phones, AT&T and non-GSM phones such as Verizon for example. I deal with carriers such as T-Mobile, Simple Mobile, H20 and non-GSM carriers such as Boost Mobile. So i'm saying that I basically deal with it all. Now the problem i'm having is my own phone. I set to WCDMA only and i'm on the stock ROM of course. The phone will set itself from Band 4 to Band 2 from time to time however, when it sets to Band 2 there is no service until it swaps back to Band 4. I have troubleshooted and called T-Mobile and Samsung to talk to them to find out whats going on. Both of the handsets have done this #1 and #2. The service menu *#0011# shows that it is on Band 2 and it is receiving 2 to 3 bars of service but the availability is LIMITED. The About Phone -> Status menu shows that it is Out Of Service. And the carrier is unknown. The notifications area shows searching... or no service. The type of network is showing Unknown:0. This only happens on Band 2 WCDMA on my phone. On any other phone it works with no issue. I am wondering why my specific phone is not connecting to this band properly. T-Mobile has told me to contact Samsung. Samsung said they can't help me apparently. So what do you think the reason is why I can't connect? If you need screenshots I can take them.

I have a similar problem with my first note 2. My note 2 gets signals sometime and I cannot get 4g speed. I called up tmobile they where unable to fix the problem. So most likely somthing screw up on your phone and use your insurance to exchange a working one.

Its never worked properly on neither of the Note IIs i've had. So 2 devices with the same issue. I believe the issue is wide spread and there are many others with the refarmed band connecting issue. The phone should have come with the options of 1700 and 1900 WCDMA switching or both. Unknown:0 just means theres no option for it so it doesn't know what to show. However, I can't explain why its happening on the Note IIs only.

Another person, as well as myself, posted about this problem about a month ago. We both had the same exact issue... 4G works, 3G doesn't at all. Edge works, GPS works... 3G DOES NOT send/recieve any data. It has to be a T-Mobile issue and from the looks of it they are trying to ignore it. Honestly it becomes a huge issue when you're traveling and can't always access WIFI or 4G. It's something I would leave T-Mobile for... so they should consider tackling the problem and fix it.

This could be the same issue i'm having due to being in a limited 4G area its mostly 3G.
However, I can access 3G and 4G on phones that are not T-Mobile like AT&T Androids and iPhones and it works with no problem. I am wondering if this applies to the Galaxy S III and Note I also as I haven't tested that out yet. That's why I pointed it out at Samsung.
I wonder if it will be fixed when LTE Radio gets unlocked.
Developers should take notice that deal with the combo WCDMA 1700/1900 handsets to create a switch to go from WCDMA 1700 or 1900 and to use a combo of 1700 + 1900. So we could have the option to switch to a specific band rather than it jumping from 2 to 4 then back to 2 and 4 again.
Are you rooted?
Are you running a Custom ROM?
Have you flashed a Radio from anything other than a T-Mobile Radio?
Is it even safe to flash a radio other than T-Mobile?

Similar problem. Network data stopped sometime this afternoon. Tried sim in my sgs2 and worked fine.thinking of going to tmo store.

Not sure but the issue with band 2 might be LTE related and the nonworking scenarios are possibly just occuring as tmo expands their towers... not sure if im way off or not but I read that tmo is pushing some to 1900 to make room for LTE on their 1700... there for, again just a hunch, band 2 might be somewhat sporadic due to it being reconfiged to accommodate their LTE rollouts

I understand what your saying but its a weird occurrence to only not be working on the SGN-II. When I can hold another persons phone in the same spot with 1900 only and it ends up working. Only thing I can come up with is maybe blocking specific devices but I have no clue. Putting people on bands that don't work properly is something T-Mobile shouldn't be doing. If you for example are on that band and an emergency call comes through well you missed it till your back to the other 2 bands that work. I always root my devices however, i'm a lil scared to due to the fact that I might lose my EFS. Even tho I know I can backup my EFS. But then again I could lose it right after root. I don't understand why Samsung put vital info into a folder that could be removed.
Anyways sorry for the rant. I'm glad to know i'm not the only one with the problem.

The GNII is one of only like 3 phones that come with the LTE "on/off switch" so thats why Im speculating still, again I really have no clue but having read a few topics (like you wanted to know everthing about tmo efs/modem/imei/etc before modding anything) I feel like the LTE rollout and the band 2 issue going hand in hand

I think know whats going on. In your *#0011# Service Menu. When it switches to Band 2 the MCC-MNC change. It shows something like 310 260 when its on T-Mobile but 310 410 when its on AT&T. When on Band 2 for some reason it will swap from 260 on Band 4 to 410 on Band 2 therefore identifying it as an AT&T network. Why is it trying to connect to AT&T? I have no idea.

I personally havent experienced any issues with my data/sms (then again if youre not receiving text/mms then how would one know they are experiencing problems in the first place?)
Because I havent had any issues I havent really tried to test my connection enough to know when im band 2 or band 4 or what exact mcc-mnc changes are occuring... for those worried about messing up their phones they need to just make sure they are always flashing a rom built foe their carriers' phone model and also make sure that each flash performed doesnt affect the modem.. (I know the modem part is hard due to roms being based off newer releases but as long as you are following my first suggestion (verify you are flashing the right carriers' phone model download) then there should never be an issue

T-Mobile's response is: The phone is designed to connect to the best network. Once Band 4 on T-Mobile has no signal while on 3G/4G WCDMA it will flop over automatically to Band 2 on AT&T. Due to the 7 year agreement we have with AT&T you should be able to access the network. However, we have lost a bunch of ROAMING AGREEMENTS recently. "Apparently AT&T DID NOT keep their promise of a nationwide agreement". Therefore your city might be on this list. This may be why you can't access AT&T. There is nothing we can do right now. Its a waiting game on when T-Mobile rolls out improved coverage onto 3G/4G 1700 WCDMA and 3G/4G 1900 WCDMA on its own. So in the future it is less likely that you will be put on AT&T. However, it is still possible. Sorry but we DO NOT have any CeI-Fi devices as I would offer you one as we are SOLD OUT. We don't expect any Cei-Fi devices to be in till this Summer.
So this device is supposed to go onto AT&T apparently and its not supposed to show as Roaming which is why Data Roaming Checked/Unchecked doesn't work.

Thank you! Finally a complete answer lol.
Is it possible to make it so band 2 only sticks with T-Mobile?

Well they sold out of the Cel-Fi once they actually dropped the 2 YR requirement extension and then they got plagued with calls and SOLD OUT. I told her thats not good that means that the network is crap. She laughed and agreed. But look at the good AT&T signal makes me want to sometimes switch but everytime I think of leaving I couldn't.
According to the info I have gotten in my area GSM is approx. 485 meters away and WCDMA is 1,110 meters away in the opposite direction.

Figured out my problem. Phone got blacklisted.thanks eBay:thumbdown:

Now I can ROAM onto AT&T and have everything running except 4G is actually EDGE speed. I can even select AT&T as the main network.

LTE Band 2 1900MHz capability
I would like to know if an unlocked Tmobile note 2 has the capability to work on AT&T LTE Band 2 1900 MHz?
I know it works on AT&T GSM-1900 MHz frequency. it will even work on LTE band 17 700MHz frequency.

[Q] Buying SM-P605 Advice

Hi Guys
Just looking for some advice regarding the SM-P605, the 4G LTE version. I am based in the UK and have not been able to find a reasonably priced tablet with 4G.
I went to the Samsung store in Oxford Street and it was £600, which is over my budget. I have recently seen a version on Amazon for just £429.99, which I was tempted to get. The model number is listed as SM-P6050ZKADBT, which doesn't seem to be a UK version.
I thought I had read somewhere that buying an LTE device from abroad would mean that in the UK you would not get the true speed from 4G, but cannot find that article anywhere anymore. The seller also responded to ask where I heard it from as there is no difference between UK LTE and International LTE.
Does anyone know if it is OK to buy an international SM-P605 for use on the EE network in the UK please? I have searched on these forums also and could not find a definitive answer.
Thanks

I have a SM-P605 and I imported it from T-Dimension in HK, it cost with all fees & taxes ~£465.
I then downloaded what was meant to be a BTU firmware for it and flashed it and it didn't trip KNOX , but rather unfortunately it installed itself as a Spanish one (PHE) instead.
Now whilst it's not the end of the world having a SM-P605 with a CSC code of PHE, I would rather it were BTU & no matter where I look I cannot find a stock SM-P605 firmware that will do it.
I've installed a 3 sim card into mine and it works perfectly, I've not bought one that gives me 4G/LTE access because it's pretty c**p coverage at the moment, so I don't feel that there's any significant advantage of paying extra for something that I can't get or rarely get.
Still at the end of the day I have a SM-P605 which works well, will shortly have a 128Gb SDXC card installed into it as well. But TBQH, I'm not overly impressed with the service that Samsung provides in regards to firmware updates for its devices so I'm considering moving to the "Dark Side" and getting an Ipad & Iphone instead.
Consider your purchase carefully, especially as Samsung have new devices out, which have now superseded the 10.1 2014 edition, as I severely doubt that Samsung will continue to support &/or issue firmware updates for it much longer, if all if their reputation is anything to go by.

Hi
I have just managed to find this quote also, which kind of backs up what you say
"The version advertised here is the SM-P605 P605XXUBMJ4 Android 4.3 variant which has the Quad-core 2.3 GHz CPU, 32 GB built-in memory and support for LTE bands 800, 850, 900, 1800, 2100, 2600. It should in theory work with all current UK 4G carriers.
HOWEVER, the latest radio firmware update available in the UK doesn't appear to support LTE. When I went to "Settings...More networks...Mobile networks...Network mode", expecting to see an LTE connection mode, all I could see was GSM/WCDMA (i.e. "H+"). The best mobile connection speed I've managed so far on a 3 Mobile PAYG mobile broadband subscription is "H+" at around 5Mbps. By way of comparison, I get solid "4G" connectivity with the same carrier on my Samsung Galaxy S4 Mini, so I don't think it's a 3 Mobile problem."
I have a 4G sim card with 3GB data allowance per month, so I am keen to use it to it's full potential, so with that in mind, I think I will give this tablet a miss. Thanks for your advice and sharing your experience.

You need to get a 4G specific SIM to get it to work, a standard mobile internet SIM won't cut it. You'll need to pay the extra to get the 4G functionality.
The 4G bit isn't worth it at the moment because the coverage isn't up to much as yet & still in its infancy, but in years time it might be better & worthwhile.

think he said he had 4g on his sim, the problem for us UK users is basically we are going to have to root the device to enable it, certainly until our providers get their finger out, which could be whenever. The way I looked at it was 'am I going to sell the tablet in the next 2 years?' if not, just root and have the benefits 6 months before they roll it out here. Samsung always been slow with updating, but then that's why people choose android, it isn't for the official stuff, it's for all the customisation you CAN do. Chomping at the bit for mine, it's an import so it's never going to be a flyer for a resale, so may as well enjoy it the next couple of years.

My 605 came from HK (T-Dimension), so like your it's an import, so it will work with the 4G networks here when they become fully operational, I'm not going to pay for 4G when the UK's 4G coverage is so poor at the moment.
When the 4G network becomes more established throughout the UK and in the area where I live then I may consider it, but I have a tablet that's 4G/LTE enabled for the future, however with me being so unimpressed & underwhelmed by Samsung's poor upgrade policy, I may consider buying both an Iphone & Ipad.

I don't live in the UK but in Australia. I bought a HK P605 and it works with 4G... As Oz uses international modems and radios too, it should work on yours.

Installing another region's s/w doesn't change your CSC. When connecting to Play or Samsung Apps it still identifies as being from Hong Kong and any regional restrictions still apply. Plug it in to Kies and it'll come up as Hong Kong.

You are wrong.
I have a HK machine, which I flashed with a "BTU" firmware and I've connected it to Kies3 and it tells me my CSC code is now PHE (Spain) and checking with the device it says PHE as well.
So as far as I am concerned the machine is now an EU one. Not an HK one.
And I still wont recommend buying one either.

When you use Kies for emergency recovery you input the device serial number. From that, Kies knows the CSC the device shipped with and the regional ROM it should be running. Of course Samsung has access to the same information. I'm running a TPA 4.4 ROM but as you can see below my CSC is still TTT. So I have no idea what happened in your situation but you'll forever have a HK device based on its serial number. I'd say it would affect your warranty but you don't have one any way.

Yes I know that and where you have TTT, I now have PHE.

Just an update, my 605 arrived today all the way from HK (took 8 days from ordering to arrival!). Everything working exactly as it should, on connecting to wifi it's already asking me to update to 'fix stability issues'. For now I've disabled it updating, not actually sure what it wants to update! To KitKat? It's my first tablet, so I'm leaving at stock for a week or so to get the general gist of it. Makes it easier that I have had an S3 for near 2 years now and it seems almost everything (menus etc) are almost identical. Put my phone sim into the note and it works no problem, I'm not on 4G at the minute mainly because it's expensive, I live in Birmingham so the 4G coverage here is excellent. Looking forward to reading up on rooting and trying out some mods, stocky's looks a good one, but I'm open to any suggestions if anyone has any Very happy with my £353 purchase, it's the 32GB version too. Seems plenty fast for me not being that experienced using a tablet. Fully expecting the same model when released in uk will easy be 600 maybe more, or more likely tied to a mad 24 month 4G contract 60+ a month plus 100 quid upfront.

Simultaneous Voice and Data?

Received my note 4 yesterday, noticed today while I was on a call that I could not connect to LTE data simultaneously as I was used to doing on my note 3. This led me to inquire why this was the case, after searching the web I found that to the best of my understanding that the new sprint phones are all coming with one chip to access a cell signal instead of two like my note 3. If I've misspoke about the reason my apologies but I believe thats what I understood. Now I'm wandering if I was to use google voice to make calls could I then access data as well? This leads to another question, my understanding is that Sprint customers can allow google voice to use there current mobile number as there google voice number. If anyone has done this I would like to know if there are concerns to have and can you opt out if you no longer want to use the service? Any suggestions are appreciated.

Wow...this sucks! I just tested mine and i cant use data while making a fcuking call. Wtf sprint

Like I said, I've never used Google voice for phone calls but that may be an option I'm just concerned about giving my phone number to google if I want to get it back.

you can always drop Google Voice from your number

Some are using hangouts. You can call and use WiFi for data if available, or you can do both call & data on WiFi.
For 95% its not an issue and Sprint is going VoIP in the near future and will be able to do both then.
The trade-off is better battery life with one antenna compared to having two.

So you can call out without wifi and use data, even with the Hangouts dialer?

So when I'm on 4g I won't be able to call someone using phone? Wtf, I can do that on my note 2...how the hell is this progress?

This is 100% Unsat!!!
I can't believe this has happened. I too need to know if this can be fixed by using Google Voice. You can keep your own number without giving it to GV, but this is completely a backward proposition.

U can only if you are on wifi or 4g while making call. Verizon and Sprint can not do data while on calls unless u are on 4g at the time or WiFi. Its the limitation of having CDMA devices. Att and tmobile doesnt have that issue

Hangouts essentially uses VoIP. Of course it will work. You're not actually making a cellular call with it.
All Sprint Spark LTE phones are incapable of using voice&data at the same time.

So the note 4 is a spark phone but the note 2 isn't?

New technology.. smh
I have the same problem with my LG G3. Cant surf the net while making calls. Its really a disappointment. Somehow Sprint needs to find a way to be able to have Spark and use data at the same dang time. My friend has the Note 4 as well and told me she could talk and use the net but I think she BS-n.

No Simo Voice/Data
With Sprink Spark, You can no longer have simo talk/text. It's a single signal. Instead of CDMA / GSM on LTE Devices. It is only allowing one. Now that isnt due to the phone. It's the towers and the tech they are using. I heard they are in the works to update that and there will eventually be a fix.
I work for Sprint.

Are you telling me a bunch of sprint user's didn't know that spark phone's wasn't capable of talking and surfing the web at the same time using the phone data network lmao? Seriously why don't you guy's look up info before purchasing a phone first lmao this has been known since the first spark phone which was what i think the lg g2 if I'm not mistaken but no wait it's sprint fault for taking the direction they choose to better their network and services lol.

a little off

U can only if you are on wifi or 4g while making call. Verizon and Sprint can not do data while on calls unless u are on 4g at the time or WiFi. Its the limitation of having CDMA devices. Att and tmobile doesnt have that issue

Most sprint phones dont have that capability, but yes the note 2, 3, and gs4 and 3 do . I have had them all and all work when on 4g and of course WIFI. It has nothing to do with the limitations of the CDMA network, its the hardware that they put in them. (as well) yes it is easier to do over GSM and they usually have that feature. though This is something that we should have been let known and also should have been worked out before putting (or lack thereof) something like taking those antennas out in play before getting the network right. Most of us cant use spark anyway! lol so now its no spark and you cant be on the phone and get 4g either, on the newest phones, G3, S5, Note 4 ETC....

With Sprink Spark, You can no longer have simo talk/text. It's a single signal. Instead of CDMA / GSM on LTE Devices. It is only allowing one. Now that isnt due to the phone. It's the towers and the tech they are using. I heard they are in the works to update that and there will eventually be a fix.
I work for Sprint.

When you say eventually... Have they actually given some type of internal horizon or if it eventually like paying off the national debt?

Why is both WiFi and LTE showing in my status bar when im on a WiFi connection? Yes, I do have download booster on, but it was doing this way before I enabled that for the first time.

General Network Signal Guru has been updated for the Pixel 6/exynos

Network Signal Guru - Apps on Google Play
4G 5G signal test, lock band lock rat etc.
play.google.com
Working great on my rooted Pixel 6, FYI this app requires root
mmarcz

I've been testing this for around a month. Works quite well but dual SIM or leaving DSDS enabled can be a little weird.
Band locking is not possible and likely will never be.

Interesting, thanks. The ads aren't being blocked by AdAway (root) and the app would cost $50 a month for advanced features, but I'm sure some interesting data can still come out of it for free.

I used this app for band locking. What else can we use it for if it doesnt support that

Looks like it's capable (and defaults to as long as it's running) of testing your connectivity. I don't know specifics and would likely only use it if I had a problem, which I haven't.
An excerpt of the description in the app store:
Network Signal Guru (NSG) is a multi-functional Android OS based tool for voice and data service quality troubleshooting, RF optimization and engineering field work. It supports all wireless network technologies worldwide, and covers multiple mobile layers as well as data stack in real-time. NSG provides extensive test functions for voice, data tests to assess and reflect the real end-user experience of QoS within a mobile network.
NSG covers all test functions and latest technologies such as: GSM, GPRS, EDGE, UMTS, HSDPA, HSUPA, CDMA2000, EVDO, LTE, NR5G. NSG integrates full recording and decoding of protocol layers on the supported technologies(3GPP, Layer2, Layer3 and SIP) and direct decoding of Layer 3 signaling and data protocol packets on cell phones.
NSG Map offers comprehensive and valuable benefits to combine outdoor and indoor measurements, which reduces the complexity of in locations such as subway, malls or airports.
NSG needs two prequisite conditions before you are using this tool. first only support Qualcomm chipset models. Secondly NSG need cell phone a super user access within your android phone and you have to root the device before NSG is running.

Notice that it still says Qualcomm only in the description, but in the What's New section:
**New**
- Exynos support (Pixel 6)
**Fix**
- Dual 5G (Qualcomm)
- Cumulative decode bugs

It's a monitoring tool first and foremost.
I'm looking forward to positively identifying new cells/PCIs, new band broadcasts like n77 or n41 SA, or emerging technologies like 5G carrier aggregation or VoNR.

Thanks for replying. I am a noob and having all the info the app gives is basically a new language. But I have a feeling even if I did know what the information is telling me I couldn't really do anything with it.
I am in the middle of switching service providers and I have a sim card of all three providers in my country. If someone can help me understand what to look for so I can choose the best provider

It depends on the carrier and how activated the sim card is, but you should be able to use NSG or other, free apps like CellMapper to measure your signals and coverage.
Carrier maps are also an option if you trust them.
And don't worry about understanding all the data. I only understand a fraction of it myself.
The key metrics are easy and for all of them, higher values (or closer to zero if negative) are better.
RSRP = Reference Signal Received Power
RSRQ = Reference Signal Received Quality
SINR = Signal to Interference plus Noise Ratio
Also useful to see how wide your signals are. A 5 MHz wide signal at 600 MHz will be extremely slow but have greater coverage than a super-fast 80 MHz wide signal at 2.5 GHz.

Can someone verify if NSG exposes the QCI on Exynos like it does on Qualcomm? My Pixel 3 XL doesn't seem to work with it and my HTC 10, which does work, isn't whitelisted for AT&T so if I put an AT&T SIM in it, I risk them blocking my SIM (and I would rather not mess with the IMEI to get around that) and the battery on the 10 is going to go totally kaput soon anyway.
On Qualcomm, this an example of what the screen looks like

I'm not very experienced with this app, but I've got it running, gave it root permissions, it's testing. I turned Wi-Fi off just in case that would help progress. Everything below the GUTI line is blank so far, but I'll leave it running for a while and see if anything happens, and report back. I have not paid the $50 per month for the app, for what it's worth.

Pixels are apparently pretty fussy because of Google so it's probable that there's more to do than just install it but I don't know what those things are unfortunately since I don't have it working on my 3 XL either. Thanks for checking though, would be a nice perk.

Thanks for checking. It probably needs a custom kernel or something. I saw a post about, I think it was the 4 XL, needing some special userdebug kernel because Google switched to AOSP variants or something like that. I only briefly skimmed it but it sounded like a hassle. Probably why it doesn't work on my 3 XL but I tried the Kirisakura kernel and it didn't work on that either.
It's not like a critical feature or anything but I help people find prepaid plans and the QCI determines network deprioritization policies and a lot of the QCI info that I've gathered hasn't been updated in years so I was going to start buying a SIM to test every so often and update all of it.

I have working QCI.
It should be noted that the app works a lot better if you disable DSDS in the phone's secret menu. NSG tends to get confused about which SIM card it should show info on if you have DSDS enabled.

What was needed to get the app working? Custom ROM, kernel? Or just disable DSDS?
Hearing that you can see the QCI has pushed me over the edge and I'm going to get a 6 next month, just need to know if there is anything specific to get it working.

Stock rom. Rooted. That's all you need. Might need a license for band locking and advanced functions.

Any idea why @mightyvenom is only seeing the IMS QCI on the Pixel 6?
Does Network Signal Guru display the QCI?
I test prepaid plans and part of that process involves checking the QCI. I know that Exynos modems have limitations that Snapdragon ones don't. My Pixel 3 XL unfortunately is not supported for NSG and if I can test this with a 6, I'll definitely...

I'm totally new to this app having only used it once to check QCI on my HTC 10 so I don't really know how to troubleshoot it.

should it be enabled? don't know much about what DSDS is. mine is also disabled, but not sure if it's because i have LTE enabled in SMS settings and curious what EAB/Presence is and it's disabled for me but not for you/

Just a note on the band locking menu. What you see is what you get. NSG exposes the entire hidden baseband console as-is. Anything you touch will persist through a reboot and that ENDC stuff is completely undocumented.
Google and Samsung need to update the modem to allow 5G band locking or toggling NSA/SA.

Question From OPPO engineers: CN version of OnePlus 11 has software defects in WiFi and mobile hotspot module

Previously, I discovered that my CN version of the OnePlus 11 was incapable of turning on mobile hotspots at 5GHz or higher while connected to a 5GHz WIFI network. I promptly provided feedback to OPPO. Today, OPPO reached out to me from China to inform me that they have identified the exact problem. According to them, the issue stems from Qualcomm, and there is a software incompatibility with my location's WiFi bandwidth. As a result, the system automatically downgrades the mobile hotspot to 2.4GHz to avoid network speed interference. This underlying software issue has been communicated to Qualcomm by OPPO, but they have informed me that they may not fix it for now.
However, I have my doubts about OPPO's response. Firstly, if the issue originates from Qualcomm, why doesn't it affect the OnePlus 11 sold in Europe? (I am based in Italy.) Secondly, I attempted to activate the hotspot separately (without sharing WLAN) using other CN version phones bought from China and connected them to the OnePlus 11. I then turned on the OnePlus 11's hotspot, but the problem still persisted. During the call, I raised these two concerns, but OPPO customer service could not provide an answer.
While we are aware that the hardware of OnePlus in different regions is practically identical, I wonder if this problem is an exception to the rule. Perhaps my guess is incorrect. Moreover, I can confirm that the mobile hotspot problem, which may be attributed to Qualcomm (or perhaps an excuse by OPPO?), has also been reproduced on my friend's CN version of the OnePlus 11, who also in Italy.

One conclusion is that the ONEPLUS 11 Chinese version has many problems, intentional or not.

Do you try to flash to OOS to solve this problem?

I tried flashing OOS, but it didn't boot. . Then back to COS I found this problem. Now my phone is in transit to one plus service center in Poland, to unlock region restrictions, but I also left a note mentioning this WiFi and mobile hotspot issue, I will wait for their detection, maybe they have a tool to flash me into OOS and test or verify?

My oneplus11 cn can wifi5 + wifi5 share. Can also wifi5 + wifi6 share.
Why?
Maybe repaired？ in cos A10.

I got a somewhere similar issue with Oneplus 11 model CPH2451 bought directly from Oneplus US, its hotspot 5Ghz band not turning on. As a result of this, the oneplus clone phone app could not work as it kept forcing 5Ghz band. Oneplus support kept asking me to hard reset the phone however, it appeared resetting did not work.
I thought this was software related. One temporary workaround to make 5Ghz reappear (not garrantee it'd work without issue) was to switch region from where I am that is Australia to country such as India and restart. 5Ghz band did show up but this procedure cannot be replicated. Meaning if I switch back to Australia then switch again back to India, 5Ghz band would not reappear...
The onephone shipped out with Dec 2022 patch originally, I swear I saw Wifi 7 support in the Hotspot menu where it was Wifi 6 in your picture. However, when I was trying to fix the hotspot problem and after upgraded the phone to Jan 2023 patch, the Wifi 7 support was gone and replaced with Wifi 6 support.
I wonder if anyone else here had the issue or its just me?
