Possible SMS fix or work around (worked for me)

I have the unbranded hd2 with hspl on, never had the sms issue. being a great fan of xda flash my fone at least 3 times a week. Every thing worked fine until i flashed the latest o2 rom 1.72.xx and i was hit with the sms bug... 'UNABLE TO SEND SMS' with a ! in a small triangle in the message. as this was never a issue i thought flashing the 1.43.xxx the original rom will fix it... nope did not work, tried 1.66 and a custom rom too but no luck.
I have been using a voda sim before i had the issue so after the official o2 rom i got the issue. when i tried flashing the above mentioned roms i had the voda sim in my phone and did not fix it.
Here is what i did..
1. Put an o2 ( or any other sim in your case apart from the sim you have the issue with).
2. flashed the 1.43.xx official rom (flash the original rom your device came with if your phone is branded flash the generic rom 1.43.xx or 1.66 so you can proceed with the next step)
3. run the full setup as you normally would. like - setup time, wifi, agree to location.. etc. and importantly setup the automatic connection for the new sim in the device.
4. sent a test message with the o2 sim.
5. shut down device not taking battery out.
6. insert my voda sim ( the orginal sim the one you use daily)
7. power device and go through the full setup again in step 3.
and to my surprise the hd2 was bak in full force.. Hopefully this may help you guys as this has certainly helped me.
cheers.

Wifi problems/ CM7

Hey All!
Having problems connecting to the university's wifi
there are a few networks, some secure (802.1x and enterprise wpa(?)), one is open
At times, even when in areas of strong signal, the phone wouldn't connect
to any of the networks, or it would start to connect and then fall out
and start looking for other networks, even when there are other, it would usually not connect to any of them and continue wasting my time
if I have a 3G data plan, i wouldn't even bother, but unfortunately, I don't...
how do I fix this?
your having problems connecting to the secured ones ?
ive had the same problems , heres the thing :
my guess is ur uni has numerous routers with same ID , ur phone pairs some info to that ID , and if u wanna connect to another router with the same ID , it wont work.
heres what to try :
next time ur having the same problem with "good signal - no connect" , just detete(forget) ur unis wifi profile , re-scan re-enter ur id/pw , and it should work .... till u try yet another router , its a pain ...
Tried it, numerous times...
didn't change a thing...
Kernel?
What ROM are you using with what kernel? Highly probable this is a kernel problem. Tytung r6 for instance does not have this problem. This kernel is delivered in for instance the TyphooN Rom on TyphooN CyanogenMod 7.
v2.4.1: Updated to tytung r6 kernel. This fixes IEEE 802.1x/EAP authentication support as well as native tethering.

I'm using
2.6.32.15-g0e4b5ff-dirty
That's the problem. Either flash to another ROM or find out how to flash another kernel.
forgot to mention,
My device isn't flashed,
I'm surring CM7 from the SD Card
A solution
I find A solution (not THE solution) : reinstall the ROM and it's work find until the next time...
the reinstall doesn't RAZ anything, so it's 2 mn time
The last comment is not clear!
Wifi peap aslo does not work for my university. I tried many ROMs
Only darkstone from SD card worked long time ago, now I am running android from nand
Same problem here ^^,
Will try to install some kernel

[Q] Help!! No service!

Hello,
First of all,
- I'm on Imilka's GB vivo (ported from mdj vivo for des hd)
- I'm using radio 2.15.50.14
- I live in the netherlands
- My network provider is KPN Hi (no data plan, only using Wi-Fi)
Yes, I've searched for this problem already, found 2 different threads, both with (more or less) the same problem, both without solution, so I thought "let's try this again"
two days ago, I took my phone and started to play some games, listen to music etc. just like I do normally, but then I got a pop-up saying "no service". I tried to connect to my network in settings, but then it said my sim-card didn't allow my to connect to KPN. I tried different roms (all android nand) and radios, but without succes. Yesterday I tried putting winmo on it again, then it worked. SD android also worked for some reason. Well I really want Android, and I really love those sense 3.0 parts like lockscreen and rosie, and I definitely want gingerbread sense, but there aren't any of those SD builds.
Do I really have to go back to winmo with a SD build?
Thanks in advance!
You can try this:
go to Dialer and press: *#*#4636#*#*
Then go to Phone infomation, select: WCDMA preferred
press Refresh than Update and Toggle DNS check (0.0.0.0 allowed)
reboot
Doesn't work either

Do you have a rom that did work? if so you can try this:
Extract the libhtc_ril.so and the libril.so and replace the ones that you have in the rom and then try again. I would replace it by pushing it into the rom and then reboot, you might need to fix permissions if it doesnt work the first time. Thats what controls the communication between the radio and the cell towers.

Hmm I don't think this will work...
first because I haven't found a working nand so far (only sd) and second because I'm a NAND Android user since it came out, but this is the first time with this problem...
And I've done fix permissions already about 20-30 times =C
I tried putting the SIM card into my sisters phone too, she had full service. The weird part is that I also put my mothers SIM card in my phone earlier, and I had full service, WEIRD. So I thought at first it was my provider's problem, because Vodafone works perfectly good, but then my sister came with her full service...
Still thanks for reply. I hope someone comes with working solution soon...
anyone?
I really need a solution... stuck with wm now. maybe going to wp7
task 29, reflash radio, MAGLDR then android rom? Might help, iunno. xD
I was experiencing the exact same thing as you describe. Unfortunately.....i prob just forgot to renew my contract :S
You were able to call with your sim in another phone??
I already did task29 and its not because of contract because Im on winmo now, and I do have service all the time..
Hi
i got exactly the same Problem. in Android no Service. WMO works well all the Time. if i set to gsm only i got network connection for 1 minute or so. Any hints???
Phil
So, some Progress....
i flashed a RUU to went Back to WMO Stock. -> Wireless Service works well.
next step i installed MAGLDR113 and ClockWork Recovery
Next i flashes this ROM:

Flashed gApps
Reboot
Can't get wireless Service
Phone *#*#4636#*#*
Phoneinformation
GSM Only
DNS check 0.0.0.0 allowed.
Now i got stable Wireless Service Connection. Only 2g but stable till now.
We should gather some Infos to find simularitys between Phones having this Problem:
HTC HD2 LEO EU-Version
Radio: 2.15.50.14
16GB Micro-SD Card 15GB fat32, 1gb ext4 for App2SD
T-Mobile DE
MAGLDR 1.13
Another thing i see on my Phone. If i deactive the PIN-Code and restart the Phone i got network Connection with 3G for about 5 seconds. So it seems there is something which kills the 3g Connection on Boot.
still no solution... anyone else pls?
I have the same problem. Had it with my phone a while back and sent it in for repairs to HTC (for freezing issue). Got another back and it worked fine for awhile. But now I'm getting the temporary no signal issue. Only solution I have found is to turn on airplane mode and turn it off.
Also, I have been able to receive text messages when I have "no signal" but cannot send them.
Running Magldr 1.13, radio 2.15, miui 1.5.27

Sounds like you might need to update to the newest radio 2.15
Check what radio you have right now
ww.4shared.com/file/rVNaZcTK/Task_29_with_Radio_2155014.html
Thanks a lot but it is not working still.
This is what I have done:
1. Update Radio ROM from 2.13 to 2.15
2. Flashing DFT_LEO_MAGLDR113_DAF
3. Recovery_150M_system_5M_cache_v3.0.2.5_
4. ROM TyphooN_CM7_v3.5.9-MAGLDR
when I figure out that phone still not working properly I have decided do flash another ROM version: NexusHD2-Gingerbread_V3.0_NAND_(Android-2.3.5). But my Leo still freezing and I can't even configure it when 2G or 3G connection established. WiFi is working very good and this is only way to use internet in my LEO.
Maybe You have any other ideas how to resolve my problem ? Please

hmm
maybe updating to the newest clockwork would help 4.0.1.4 works really well on all roms i run and i do a lot
but the main culprit is THE APN settings
go into wireless settings>mobile networks>access point names (apn)
make sure you have the right settings in there for your provider
i remember when android first came to hd2 i had to input those setting every time i put a new rom in.
i dont know who ur provider is but it should be easy to find out the proper settings for it and then inputting them and saving
otherwise it could be your sim card
see how it goes ..... see what the apn settings are for boyppc and just copy them to other roms
you could PM me too
panie wojciechu nie ma problemu
Po polsku piszemy ?
I'm gonna check this settings. but in my opinion this is hardware issue. When phone is freezed - mainboard temperature is increasing. Sometimes I must wait until temperature decrease to normal becouse Android is not starting. It's stop on Go go go screen of MAGLDR.
When 2G or 3G connection is established I can download files or browse internet so I think that provider (T-mobile) settings are ok but as I mentioned I gonna check this out.
Thank you again
I agree when the phone overheats it freezes and turns off. Turning the phone on before letting it cool off will cause boot failure you're describing. Frequent overheating can ause the touchscreen to stop responding as well. It happened to my phone too, thank god it was under warranty. Since that day I stopped overclocking it.

I'm also facing the same issue since yesterday, if you get any solution please update me.
Thanks
Have you guys any update on this? I'm having the same issue. Tried all kinds of resets, flashes, etc. (except for QFIL). It happened to me a few weeks ago too but the phone just started working again after 1-2 days. The issue seems to be that the radio won't turn on. One interesting thing I did notice was that my phone seems to be detecting my SIM as Canadian, which it's not. This occurred when I did a fresh CyanogenMod flash. When doing the initial setup, CyanogenMod flashes up a message about detecting the source location of the SIM card and then sets the language option to match.
I've contacted zuk.eu about it but no word back yet. Not holding my breath. I'll try and get my hands on a SIM card from a different mobile operator after work and see if that makes a difference.
Well, another case of Zuk Z1 with the "no service" (in the shorcuts the airplane mode is off but in the power menu is on even having reset the phone). I wiped everything, I flashed different roms, in the end I flashed with QFIL the stock rom with his recovery, and there is no way to fix the problem.
I'm trying to make a list of users that has happened the same because apparently is not a single fault.

Add me to the list .
Since about 2 weeks I get "no service" with airplane mode in power menu.
I think I had a similar problem some months ago, when I pressed the LTE button in pull down menu. But it was working again after some minutes or reboot or something like this.
I use two sims, and when the problem started 2 weeks ago, I think one of both SIM cards was working longer than the other one.
In the evening I saw, that one of my sim cards (calls + sms) did not have signal (0 bars), but I was not investigating this, because the other SIM (mobile data) was working without problems.
The next morning, the mobile data sim was without signal too and at "no service".
All was on stock rom. Now I tried some CM13 and different kernels, but this did not help anything.
Hopefully there will be something somewhere to get our phones back to work

Apart from you I have found two more cases.
One on one phone repair web and another who has answered my posting on the Zuk Mobile Facebook page.
Airplane mode error fixed?
What sorcery is this?!.
I had already given up with the Zuk Z1 airplane mode always on error. There was no way to remove the message "No Service" even after full wipe and flashed a rom+recovery stock (COS 12) with QFIL.
Several weeks later I decide I'm going to use the phone as a media player, back to flash TWRP recovery with Mauronofrio Tool All In One and install the official CM13 ROM (snapshot 20160418). Before I used the unofficial CM13 version of Coldbird (with the mm-firmware.zip).
A few days later, out of curiosity, I look if the airplane mode is still activated in the advanced power menu and is listed as disabled!. I insert the sim, in the *#*#4636#*#* the radio is on, and now I could make and receive calls (and connect to LTE / H / 3G networks) the last three days without problems, and I've even been in areas without coverage and then the phone reconnected with no problem.... !
Now I'm using the 20160602 nightly CM and Radioactive Reborn Kernel smoothly (only some reboots occasionally). I still do not know what happened with the phone and if it has solved the problem at all or is temporary and will fail again.
@Kausik2888, @gkanaje and @bromän report the same problem in this thread
Hello friends,
Even i am facing the same problem. The phone is always on 'Aeroplane' mode.
I tried CM12.1, CM13 and again flashed the stock ROM, but no use. The phone never comes out of the 'Aeroplane' mode. The GSM Radio status is always OFF and cannot turn on the radio from the phone info menu (*#*#4636#*#*)
Initially it was working fine but since i was not getting good signals inside my room i changed the preferred network from '4G(recommended)' to '3G' and boom !
The phone has lost the signals from that day. The phone detects my simcard, the IMEI's are valid but 'No service' / 'Aeroplane On'
Attaching logcat that i took after i rebooted my phone - https://pastee.org/p4rmf
Am also encountering the sane aeroplane mode problem in lenovo zuk z1 which I bought a month back.. Guys please suggest me the solution what should I do? Is there any way to overcome this problem
For me it was same issue few days back in my Zuk Z1. I read some where that it is 4G band related issue. So, i applied few steps and now it is working -
1. Take sim out from phone (no need to power off). Put aeroplane mode off from both power button option and settings.
2. Power off mobile. Put Sim back in some time (1 hr) and change preferred network from 4G to 3G.
No service radio service off on sim
