Welcome to Vodafone Community
So, like all of you folks, I installed the update on Saturday when it arrived, and experienced exactly the same issues.
Couldn't see/activate SIM, yet could receive text/calls but no data. Network settings all greyed out.
Ended up doing a full factory reset. Same problem, but now I can't even receive the calls or texts and still no data.
Spoke several times with Vodafone customer tech help via chat, told the same stuff about it being a few hours etc etc.
Using an old PAYG GiffGaff SIM (with no credit) recognises the SIM, gets bars for signal etc.
Doing the *#*#66.... test code thing to get to the Xiaomi hardware test shows that there's no SIM with the Vodafone SIM installed but that there is a SIM with the GiffGaff SIM installed.
Vodafone SIM works fine in any other phone. My wife's Vodafone SIM also doesn't work when put in my Mi 9.
So, after not having any luck on the various Xiaomi forums I found this one a few days ago and have kept an eye on it. I was somewhat hopeful when I saw the various posts about the new patch, but less so when it seems that it doesn't work for most people, unless they try the factory reset option.
Still, I figured I should at least try it, so I went to the update checker and found that my phone has no available updates. I'm still stuck on 11.0.1.
Thanks Vodafone. My phone is still pretty much useless, and no offer of help.
Well, Mr Xiaomi man just told me that "higher management" has said 11.5 will be out by the end of the weekend.
They weren't wrong about the previous patch coming out, it just didn't work so fingers crossed.......
I just cannot seem to understand how the new update has fixed the issue for some and turned into a new issue for others!! Baffles me.
Could it make any difference if you did the new upgrade with or without the SIM installed at the time. I did mine without the SIM , then inserted it and reset APN. All ok. Just a thought- from someone who knows very little!
So my status this morning is as follows. If I put the Sim in the "inner" slot in the tray - I get no sim recognised. A sim shape with an x in it. If I put the Sim in the "outer" slot in the tray - I get a greyed out bar symbol with no access to the APN section of the sim card menu.
Spoke with Andy from the CEOs office yesterday afternoon who promised to keep in touch.
2 things are reported as working - putting in a new Sim and a factory reset. The reset is quicker - a little nervous as it is a somewhat nuclear option but its quicker than a new sim and I've zero hope that this will be fixed via system upgrade. Quick poll - anyone done a factory reset after downloading 11.0.4 and NOT had it work?
So am i no way an expert or know what I am talking about. however just looking at what worked for me. the new update to 220.127.116.11 didn't fix anything on its own (I am thinking its an issue where both the xiaomi system and the Vodafone system are sending for sim/ apn settings and hence its getting confused/ wrong settings). By what I did above essentially (I think) stopped xiaomi sending for settings and allowed vodas to install. Like I say I'm just guessing so please don't take as a definite resove. As a side note voda only activate one sim slot so one will always just show as a sim with a cross
All up and running again finally Thanks for everyone's advice and support its more than we've had from Xiaomi or Vodafone.Doing a full factory reset is such a pain you spend so much time and effort customising your handset to work for you and your lifestyle habits but what can you do !!! Life's pretty scary right now and s#@t happens now and again, a software failure pales into total insignificance when all around the world is going into melt down Still Love my Xiaomi Mi9 and Still believe Vodafone is my network provider of choice going to spend today resetting my handset and having a proper look at Miui 11 let's hope both X&V learn some valuable business lessons before they release 12 to us Mind you it will probably take another 6 months before that happens Stay Alert Stay safe and enjoy a pleasant weekend everyone...
Having already wasted precious time on this all week, I am going to give Vodafone (through whom I am paying for my device) until Monday morning at 8am to deliver a fix that does not involve a factory reset (twice in a week, with all the time-demanding and fiddly resultant personalisation and customisation involved is asking too much). After this deadline I will escalate this to require compensation for loss of services and time invested (with no guidance from Vodafone) in trying to resolve this myself, using this forum.
Vodafone, take note - you have been warned. Now over to you...
I did the factory reset after the new 18.104.22.168 and it solved the problem, back up and running again! Yes it's a ball ache to begin with backing everything up but if you do it throughly it was quite easy in the end, all my apps downloaded automatically and in a way it's like having a new phone again! Just a few tweaks here and there and signing into everything again, if you're having doubts, do the factory reset! Hope everyone who's still got problems gets them sorted quickly!
Bizarrely, I'm now concerned why mine update worked without a factory reset. Everyone else seemed to need to do one. Am I missing something - everything seems to be working. This whole thing is making me paranoid.
Also, when another update turns up for those who still need it, what would happen if us lucky ones ran the new update? I shall be afraid of updates forever now but we will still need them at some time.
So that worked. Thanks to Digger-9 for the step by step notes - very helpful. Trying hard to convince myself that I made some smarter choices when setting up this time which will make my life easier in the future, but I think that's just me trying to dredge some positivity from this whole debacle.
Will now spend the afternoon getting everything back how it was. Most amusing was the text that "Andy from the CEO's office" sent saying he was "reviewing my complaint". He obviously wasn't reviewing it that closely as I couldn't receive texts...
Now to compensation...
Hi all, I'm sorry for any confusion caused in my last post and it's good to see resetting your network settings has restored things for a couple of you.
To those that have tried a factory reset, thanks so much for keeping us up to date on the thread here with how this has resolved things for you. I appreciate this would have been a last resort and I'm sorry for any inconvenience doing this would have caused.
We've since been advised that resetting the APN settings can also do the trick (as some of you have already mentioned). If you haven't tried this already, please try Settings - SIM cards & mobile networks - Select your SIM - Access Point Names - Tap Reset. You may then need to enter your APN settings again if this hasn't automatically populated for you.
Should you find this step hasn't worked for you, please do try a factory reset if you haven't already. Before doing this please ensure to back up your phone so you don't lose any important files, pictures or videos. You can do this by connecting your phone to a computer, using Google Drive or Mi Cloud.
If after trying all of the above steps, please do get in touch with us on Twitter or Facebook with the details requested previously. We ask you to reach out to us there as this is a secure way for us to access your account, so please don't share your information in the thread here.
For those of you who don't have a Twitter or Facebook account, please reach out to us on Live Chat, by calling 191 from a Vodafone mobile or 0333 304 0191 from any other line.
1- I am not doing a factory reset. Ridiculous to suggest that this should be necessary.
2- APN settings are greyed out. Can't do anything with them
3- Xiaomi have said 11.0.5 or whatever it is is supposed to be available at the weekend. Why are the two companies not aligned.on progress? Again, ridiculous.
4- if we are in contract with Vodafone and the next patch doesn't work can we just request a new handset?
I reached out to the Facebook team yesterday as Natasha advised. They pretty much said "Ah, yeah, sorry about that" and offered no assistance at all.
Would not advise anyone to talk to them.
The steps I have posted in the factory reset seem to be working for some in other forum too. Not saying it will fix all, but seems to for some. Wonder if Vodafone will offer me a job, apparently tech support is pretty unskilled role haha
