Unfortunately the Enter Pin UI is from the new Nexus 7 so the resolution is different, numbers are cut off and touch acts weird. Is this a known issue?
Could you post a screen shot please?

The framework is from the tilapia kot49h factory image so is the correct one for the device.

I have screen lock enabled but it seems fine for me.

Bugger. Can I say "bugger"? Bugger. There. Said it.

Well, after hours of swearing and guesswork, I finally got the WugFresh thing to talk to the Nexus on Win7, and even saw it as a removable device. As far as I know, I got it backed up, rooted and installed the KOT49H SMS WiFi Tether ROM.

It's now stuck on annoying initial Wifi setup stage (which I've been through a couple of times already, as part of this process). It alternates between "Just a sec..." and

Connecting....
Web page not available

The web page at http://clients3.google.com/generate_204 might be temporarily down or it may have moved permanently to a new web address.

Here are some suggestions:
(etc)

[Cancel]

Any ideas?

Incidentally, during the Busybox installation, I attempted to change the location to xbin, as instructed by the WugFresh thing, but didn't get a chance, so I tried to uninstall it, which it told me had failed (and that my device might now be unusable and that was basically just tought). I then tried to install it again, this time in xbin, and it told me it appeared to be the same as the one already installed.

I'm tempted to just try the 4.3 factory image, which is what I was going to do in the first place.

Okay. I've finally got it working again.

Was there a guide somewhere that explained the process of using WugFresh? It was just a bewildering set of choices, with insufficient explanations of what was likely to happen... or what was currently happening, in a seemingly endless cycle of reboots and setting up Wifi. I've been through that whole Wifi setup stage several times today, and i use a static IP, and a very long password for the network so that really wasn't a lot of fun.

Incidentally, I thought it would be fairly clear when I was done, but I really wasn't sure. I found SMS options in Hangouts, and managed to send and receive an SMS though.

I've now discovered - moments after giving Three Mobile £10, that the type of SIM I've topped up can't be used for internet access from a tablet. No reason given, it just can't. They'll probably refuse to give me the money back too. I gather they wanted to sell me a monthly data plan, which i have no interest in buying, because I'll be using Wifi most of the time so it would be a total waste of money.


Anyway, should I now stop Google Play updating Hangouts, or doesn't that matter? Do I also have to turn off system updates, to stop it reverting to not allowing SMS?

Great work +GuyAdams. So glad to get back SMS feature on my Nexus 7 GSM (2012) / tilapia on 4.4.2 (KOT49H).

I'm using 8ms messaging instead of Hangouts and it's working great.

Thanks again. Much appreciated.

Well, SMS is definitely working, so thanks again, GuyAdams. Getting 3G internet access may have to wait until I can find a carrier who's prepared to sell it on terms I can agree to...

Does anyone have insight into using USSD codes, e.g. to check on PAYG balance? I've been trying a Sainsburys PAYG SIM today, which is based on the Vodafone network - but so far, I haven't risked any more money on buying credit, after the Three Mobile / Hutchison 3G experience.

According to the Sainsburys mobile FAQ, the only way to check the balance is with *#1345# - but that doesn't work, as far as I can tell, i.e. USSD codes in general don't work on the Nexus 7 3G.

Did they ever work, in a previous version of Android? I'm still not too opposed to the idea of just reverting to an older version, if that works, and turning off the system updates forever. Apparently some data plans can't be used without them. Using PAYG without ever knowing the balance would be a total pain too. Vodafone has a 2345 number for doing it, but they don't allow that to work for Sainsburys customers, and the Sainsburys online account doesn't appear to have a way of checking the balance either.

I have a phone that the Sainsburys SIM worked in, but I had to snap the edges off to get it to fit in the Nexus 7 - i.e. turn it from a normal mini SIM into a micro SIM by popping out the micro SIM part from the outer part. That's not an easy process to reverse... I could maybe do it with glue, but there's no easy way to make it interchangeable between the two devices.

I'm not aware of USSD codes ever having worked on Nexus 7.

Honestly you will probably just need to use the SIM in an external device to do anything requiring USSD or phone calls. If you have no adapter, micro-to-mini adapters are very cheap. It will also fit in any phone that uses micro such as iPhone 4/4S, most current-generation Androids, Moto G, etc.

I see. Thanks, cmstlist.

I don't own anything else that takes a micro SIM, but the adapter sounds promising. I assumed the thickness was critical, so I didn't realise that could work. It would still be a total pain to use, of course, and would cause a lot of unnecessary wear and tear on the SIM slots.

I've read quite a bit about PAYG balances bleeding away due to unintended polling, syncing and so on. I have a Nokia C3 that liked to use the GPRS connection in preference to the Wifi connection too - it went back in its box, and will probably stay there, for that, and other reasons. I found a hack to stop it, but I've never really trusted it since. I see the ability to check PAYG credit easily as essential for anything that with internet access.

I guess I might have to just add Sainsburys to the failed list too.

It seems those adapters can be deadly too:

http://www.allaboutsymbian.com/features/item/14444_The_Curse_of_Micro_SIM_Adapter.php

That doesn't really surprise me. The manual / user guide for the accursed Nokia C3 even says it shouldn't have a combination style mini SIM with a micro SIM pop out bit, put into it. As pure mini SIMs are getting hard to find, I'd considered needing to fill in the little gaps with epoxy, or maybe hot glue (it's amazing what you can do with hot glue :)) - that was before I decided the C3 was just a total piece of crap, and not worth the trouble of keeping it alive though.

What gets to me about the Nexus is that I thought I was buying a quality product (for once), that was also mature, in that it's now already being upstaged by a replacement model. There's a lot to like about it, but then there's this huge "gotcha" with the 3G support. I expect the 3G does work, but it's let down badly by the related features not working, that the carriers all seem to expect, and rely on, to get it set up and to keep it managed.

It's on Google Play and it's brilliant ;)

Search for "8sms" and thank me later :)

Thanks. I was searching for "8ms". I've found it here:

https://play.google.com/store/apps/details?id=com.thinkleft.eightyeightsms.mms

I have the type of adapter that snaps firmly around the card. Haven't had any trouble using the SIM in mini SIM devices.
Thanks. I missed seeing that post before. Do you have a link?

As it happens, I tried fitting the 3G SIM into the discarded mini SIM sized piece of the Sainsbruys SIM, and it's not a bad fit, just not very firm. It would certainly work for a permanent conversion with a dab of plastics epoxy, spread thinly over the gaps. I expect the chances of getting a refund from Three / Hutchison 3G for miss-selling me the credit are basically none, so I may as well try.

I haven't tried it in a phone yet, in case it comes loose. I think my ChaCha might take it, but it would need to be unlocked first... AFAIK it's locked to Vodafone and networks based on it, like Sainsburys. It's currently on ASDA (another virtual phone network on Vodafone), but they've switched to EE, and I won't be able to keep it on that much longer.

I've ordered another couple of Sainsburys SIMs, so I expect the outer part of that should be a better fit. From what I gather, they only do the combination mini/micro sort, even though they ask which size you want when you order one. Maybe they just ask for market research purposes.

No problem, Keneth.

I use an infra red keyboard with my PC, and it's getting a bit old, so it often misses out letters I think I've typed. As I'm still on probation in this forum, I can't edit posts within the first five minutes, so I've got a bit obsessed with the Preview button :)

Honestly I just went on Craigslist and looked for micro SIM adapters. Someone was advertising one for $5 that was sold in one of the Chinese malls here and I bought it.

I also have two more now, though. One was when I took a SIM to a shop in the same mall and they used a SIM punch. They filed down the edges very precisely and the shell works perfectly as a snap-on adapter, not just for that micro SIM but any. The other is my WIND Mobile SIM which came as a micro with a mini shell that again snaps onto it very perfectly. Used that combo in my Galaxy Nexus until I switched to Nexus 5.

Fair enough. I might just stick to using the outer part of mini/micro SIM cards from phone companies I decide not to join :) They're free, and even though each company might only let me have three or four before they cut me off, there are a lot of phone companies. Maybe Sainsburys will get their act together and provide a more convenient way to check the balance, eventually.

My 3G SIM was clipped out of a mini sized one, in a phone shop, but they didn't give me the off cut. I've glued it into the discarded outer part of the Sainsburys SIM, with a plastic model glue called Contacta. It's working in my ChaCha, so it turns out that wasn't locked. I now have a second Sainsburys SIM, so I'll take it out of the mini part as carefully as I can, and keep it as an adapter.

Running KOT49H downloaded, flashed, and wiped cache&dalvik. After power on I see the default SMS option, but no tether option with my prepaid at&t data connect plan. If I remove the sim tether option is there.

Yes that's a separate issue where AT&T SIM cards trigger the disappearance of the tethering menu.

The mod replaces certain system files with modified versions. Since the system files in CM11 aren't the same, of course it won't work.

Frankly though, CM should be fixing this in the source code. I'm surprised if they haven't.
