Note 8 - Motherboard replacement - Calling Problems - Everything Else Working - Samsung Galaxy Note 8 Questions and Answers

Hello,
So my original note 8 was N950F 256GB Dual SIM bought in 2017. It kept on working fine, until recently it started giving the problems in mentioned order
a. excessive battery drain
b. not being able to charge wired or wirelessly
c. complete blackout.
I went for a lookout of a replacement 256GB , and was able to find one on AliExpress, risky as it always is, i took my bets to order one after some correspondence from the seller who seemed legit and helpful.
Fast forward 22 days, I got the motherboard, installed in my existing body and housing, and voila it turned on and apparently seemed to be working fine. However i came to conclusion that it was originally a N950N (maybe Korea Dual SIM) motherboard which was flashed with the firmware/CSC/baseband for UAE reigon , maybe it was done by the seller knowing my location for ordering and the usage reigon. KNOX status was tipped as well, but it is not rooted as of now (maybe reverted to stock) , so all root sensitve applications (banking , netflix etc) do work as well.
The problem is, though everything works as intended. I am unable to place and receive voice calls reliably. Most of the time the outgoing call never gets placed on the network and drops after waiting for 8-10 seconds, and the incoming callers inform me that my mobile was out of reach for them to ring me.
I suspect it may have to do with the correct baseband not being compatible with local service providers.
Seeking expert help out here for the guidance , download location and the right combination of the firmware components to be used to bring the phone back to a reliable voice calling status to be used in KSA region
All help is much appreciated.

E-Mail from HTC europe

i received this e-mail this weekend in regards to my breeze always dropping calls. it refers to a new update but only via the support centre
Good Morning,
?
The fact that your calls drops is?not normal, if it does that you should try
to Hard reset the device.
If the hard reset doesn't sort the issue you will need to send the phone to
repair.
Note: hard reset will delete all data from the device, you need to save your
personnal files and synchronize your device first.
I can confirm we have recently released a new ROM update for the Mteor.
?
Due to the complex nature of this ROM update we will not be offering this
download via our website. Instead we are offering it through our network of
repair centres.
?
From the information you have provided your local repair centre are:

does anyone know what the turn around time from being received to being sent out from HTC is?
in regards to a software update and a repair/replacement which would include any tests they'ed need to do.
thanks
HI, just try to deactivate the Umts Bandselection... means don't choose Auto .... just try GSM only....
i have Problems to when have activated the AUTO feature...
steve
i have done, thought it fixed it for a whole day aswell, however it seems to make it happen less but it still happens a few times a day
well got the phone back, they actually replaced it so got a new 1 out of the mix and the fact i bought it off ebay second hand - bonus!
the dropping of calls still occurs but it seems its the 3G orange payg sim i have. i will try and get a new one out of orange on saturday and see if that works, i know its the sim as i tried a orange 2G payg sim and it has no problems whatsoever
so its oranges fault and HTC's for not making it work correctly with the sim.
Dan
No new rom on it then? ;p
the rom had a .3 at the end of it instead of .1
the radio was the same too.
My MTeoR arrived today. I also have a "3G sim" or whatever they are.. the one that came with my Nokia N95. That same sim has worked perfectly in my E50 for the past three months, but in the MTeoR I am frequently being disconnected during calls, and even when the phone is off-call, the display changed from "3G Orange" to "No Service" quite frequently.
This is no good
wow, i know it doesn't help its nice to know its not just me breaking the phone like i seem to do to everything electrical
by the way t-mobile, vodafone sims i have work fine in 3g mode, its obviously a orange problem. i have e-mailed them again asking if its a common problem. all i can say is you do the same and maybe our collective voices will be heard.

Sudden 3G Network Problem on a Kaiser

My TyTN II developed a strange problem during the last week. It’s all started one morning when I suddenly discovered that I can’t make a call. Every call that I tried to place ended by itself even before I hared a first deal tone. I’ve made a soft reset and the phone took unusually long to find a local network (Orange). I call the network operator and was told that in my area they don’t have any problems. After some more trials I’ve made a hard reset. Reinstalled my software and it seamed to work out. But about three days later the problem returned and in addition to it the TyTN eat up almost fully charged battery over night (just once, it didn't happen again).
I couldn’t place a call again, but this time a hard reset didn’t help. What helped is that I changed the network type from “Auto” to a GSM. That means that I have excluded 3G WCDMA service.
Now, at least during the last two days, the Kaiser phone is working, but without 3G. I visited the local technical center (they are not specialized in HTC phones) and they told me that they can’t see anything particular wrong with the phone, but they are not a specialized HTC service center. So, what’s wrong with it? During the last 3 months I had 3G services without a problem. Sending the phone to a specialized HTC center (abroad) may be costly and they also may not find anything wrong with it, because phone if set back to the Auto mode sometimes even finds the 3G network.
Did somebody have a similar problem? Please help. What it could be? Problem with the phone? May be the SIM? Or just the Orange service network got crazy?
I have an original ROM:
ver. 1.56.405.5 (08/28/07),
Radio 1.27.12.11,
Protocol 22.45.88.07H
Hi there,
I had exactly the same problem. I first thought it might be with my sim card but it worked fine on other phones.
I have since sent the phone to HTC and had it repaired -- works fine now.
Hope this helps.
I had the same problem on my Kaiser when it first arrived from an ebay sale. Worked fine in GSM/Edge mode, but would not make or receive calls in 3G mode at all. Finally sent it back to HTC in the US who repaired it at no cost (thanks guys!) and shipped it back to me.
It's been working fine since then.
I read lots of others who have had this problem and the fix seems to be returning to HTC for repair.
/drt
I had this problem and still have. I send my phone back 4 times. First time something went wrong. 2nd time it got a motherboard replacement (for the 3G chip) it work even better then when I bought. It lasted for 14 days untill the 3G failed again. I send it back got and Worked for 1 day again re-send it they called me said it's working fine with them (3G options) and they can't find any problems with it. I received the phone back. Worked for 1 day again on 3G then again the problem. I have checked with my provider no problem. Tried other sim cards issue is still there. I'm keeping it here till the Xperia gets out then I'm sending it back untill the 3G issue gets fixed.
No matter what issue this phone has, it's the best on the market imo, that's why I keep up with it.

My TyTN II does not work in 3G

One month ago I bought an unlocked TyTN II to be used with my current number from AT&T.
The phone worked to an acceptable quasi-average performance in the US (NorthWest and NorthEast). Few days ago I traveled to Miami, Florida and the phone lost contact with the AT&T network.
Later I find your Forum where I could find a partial solution. After several trials and errors I installed the following HTC ROM version 3.28.405.0 WWE (Radio Version 1.66.17.56 and Protocol Version 25.83.40.02H)
This particular ROM worked in my phone because you can select the Network Band (the AT&T versions do not have this option): here I manually selected the band GSM avoiding the phone to automatically switch to 3G. For some reason any of all the ROM versions in this phone loss the Network connection when it goes to 3G . Only the ROM versions from HTC has a software piece that allows forcing the manual selection of the GSM band.
Of course, this is not “the solution” because I would like to use this phone with 3G and more.
Anyone has had this problem and found any solution?
There is a well-known problem of early Kaisers having a hardware defect and the 3G radio dying. Mine was included in the lot. Return to service was required and the mainboard had to be exchanged under warranty if still valid, which was usually the case as it happened relatively early in the product's life. Reports of it are getting rare now as most of the faulty ones have been fixed, and newer ones were corrected.
I don't have the link to the thread collecting most of us doomed users anymore, but could try digging it. Search might help you.
The common fault was that in 3G mode the device would show network bars, but would not be reachable when called, and when trying to call it would just drop.
HTC-US Resolved my Problem
I owned this information to this forum:
After many workarounds and trials/errors, I called to HTC-US explaining my problem with my TyTN II.
They worked in following way:
1. I sent them, to my cost, the phone (they asked to send only the phone without battery, back cover and SIM)
2. They took in deposit the information of my credit card just in case they needed to use it for a payment if the repair is out of the warranty. If this were the case they would inform me the amount and I had to decide to make the repair and pay the charge or not to make it.
They told me that they had to change the phone main board: I believe that everyone who has a similar problem like mine (bad or not connection to the 3G network and sluggish touch screen) should contact HTC-US to Customer Care Department, 1-888-617-1113, M-F 9AM - 6PM EST.
In my case the phone was in warranty (although I flashed the Hard SPL in the phone, but the hardware was untouched). Therefore, I had to pay…zero. And they returned my phone in just 4 business days.
My phone is working very good, always connected showing an H indicating the use of a HSDPA network.
The cost of the solution was $ 20 by the FedEx service to send them the phone. Good deal.

[Q] Why is my Gear S not able to register on TMobile's network anymore?

My wife bought me the international version of the Samsung Gear S (SM-R750W). She said that she researched and from her understanding it should work on the T mobile network. From what I've found though the consensus seemed to be it would not work, or if it did it would be spotty at best depending on the specific towers/area you were in because Tmobile utilizes different network types in different areas.
I decide to give it a shot anyway and went to the T-Mobile store where I signed up for the wearable plan and got a new nano sim card. I was crossing my fingers but as soon as they put the sim card in the watch it came to life. It looked to be working fine but as I left the store I received a text from T-Mobile stating " the SIM for your wearable devices is in an ineligible device. Services to the SIM are locked until it returned to your eligible wearable device".
I pessimistically started thinking well great, there goes that idea. But as I got into my vehicle I shut my phone down and tried to see if the watch can work on its own as a phone when unencumbered from my Note 4 bluetooth/WiFi data connections. It worked perfectly-I started calling my friends and they couldn't believe I was talking on a watch phone. Several I actually felt the call sound quality was better on the watch speaker phone compared to normally speaking on the Note 4. I called customer service but they told me they couldn't see anything and if it was working fine not to worry about it.
For the next eight or 9 hours it worked perfectly and I was using it a lot. I drove around large swaths of town and neither data nor call experienced even the slightest issue - for once I was happy to be wrong.
Eventually, as I am oft to do, I fell asleep. When I awoke this morning the watch was no longer connected to the network. It gave me a message saying it was unable to connect and did I want to scan for additional networks. I selected yes and it was able to find the T-Mobile and ATT networks. T-Mobile was selected and a "registering" notification was displayed. It took awhile but eventually said it was unable to register with the network.
I call T-Mobile and they said pretty much exactly what I expected them to say -that because it was not a T mobile device they could not ensure proper operation. But he said (and he characterized this as "good news", "light at the end of a tunnel" and "viable solution” Seriously said all 3 things.) I could either forget all about the cellular connection and just use this as a companion device OR go and buy a new Gear S from T Mobile if I really wanted that feature.
I’m truly and utterly baffled that he believed his suggestions merited the positive sayings from above. Never in my lifetime has my head been closer to exploding.
After I was finally able to speak again, I explained that it seemed unlikely to be an issue with the watch. If my Gear S was working perfectly yesterday and can still detect Tmobile & ATT networks, then something on your end seems to be preventing registration. He agree to file a ticket with the engineering team and tomorrow I should hear from them hopefully. He also told me to go and try another nano-SIM, gratis, at the Tmobile store. So today I went and as soon as I put the new card in all systems were go. I assumed that I somehow had received a bad card because here again now, data and voice are connected.
This time I didn’t even make it out of the parking lot before it notified me that that it was again unable to register with the network. There is conflicting information regarding the radio frequencies and bands that the different Gear S models have and I didn’t have high hopes. But then it actually did work, WELL, so any ideas as to what is going wrong?
I don't know how I put this in the wrong forum, could one of the mods please delete it? It's already been reposted in the correct forum.

Question Anyone Have ZenFone 8 on Verizion?

it looks like it has the right frequencies to operate on Verizon, and it will initially connect to the network on boot, but then drops off.
Any ideas here?
Hi - Mine arrived over the weekend and I put in my Verizon 5G sim card and i was able to connect to verizon data network. All things data worked.
But I can't place or receive calls as volte isn't working (my account has volte active). I don't have 5G where I live - so I'm on the LTE network.
I opened a support case with Asus this morning - they said to wait 24 to 48 hours for their engineers to review it. They originally told me to call Verizon, which Verizon told me they can't help. Verizon said Asus has to work with them to get the phone certified. I'm not sure what to do at this point except wait for Asus to reply. I will be returning it if they don't get it sorted out very quickly.
Out of the box I had data only without ability to make calls. After rooting the the phone and installing LineageOS I was able to make calls and and operate the phone on Verizon network without any issues.

Can anyone confirm this? And if so, why does LineageOS work, but not the default ROM?

I just tried it and it depends. I had the exact same symptoms:
- Data worked fine
- Texts works fine
- Calls didn't work at all
And I installed lineage 19 and then everything is normal and great. No idea why though.
EDIT: I installed lineage 19, staxisos, omnirom and all had this problem:
- Data fine, calls, fine, texts could send
- Couldn't receive texts.
After the level 2 verizon tech told me the phone was a loss I returned it. Now after doing a ton more research I found out that it might be because I simply took the sim from my old pixel 4 and popped it in. It seems you need a new sim card or you need to somehow have your line switched to be "cdma-less". Looking at these articles:
r/verizon
r/SonyXperia
OnePlus community
The guide presented on the oneplus community gives me hope I could still use this phone with verizon, but it appears to be a daunting task. If anyone has navigated the customer service and succeeded with this specific phone, I might rebuy it.
