HTC Elf crashes when accessing the SIM

Hi there,
I have this strange problem with my HTC Elf. The problem existed with the original ROM (5.0) and after my upgrade to 6.5 as well.
It started once a Month, but now it's twice a day.
If i receive or make a call, receive or send a SMS the device just shuts down immediately. (like a hard reset).
The device then automatically starts up, i get the "Smart mobility" screen and then it starts over again. The boot cycle runs endless, until i remove the battery and start again. Sometimes i need to remove/replace the battery 3 or 4 times to get it booting up again. (Doing this booting drains a lot of battery power)
If i remove the SIM Card, everything works fine for hours and booting isn't a problem at all. So I believe accessing the SIM Card somehow craps the device out. The boot-cycle seems to happen in the last stage of booting, when the device first tries to access the SIM card. (That's something i have to suspect, cause there is no way to log the booting).
I don't believe that it's connected to the ROM Upgrade to 6.5 i did, as the problem happened in 5.0 as well... (btw. everything is much faster and more light-weight since the 6.5 upgrade. It's just great.)
Here are my questions:
- Is there something, I could log the boot process, to see what's the last action when it starts over again?
- Is there something like an event log in windows, where I see the last action or even failure / exception, before the device restarts while doing a call / writing an SMS?
- Did anyone see this happen before?
Thanks for any input!

Hi
Have you tried to change the Sim card or use another one just in case the sim is the problem?

Hi Tito,
I plan to swap SIM's next weekend. But i don't get how a SIM can crash the whole thing. I would understand getting errors like "Can't read SIM" but auto-resetting the whole device?
Anyhow, I'll post an update after trying another SIM. The whole thing is, that it's not reproducible by a specific action one could take. So if the device keeps up even for 2 days with a spare SIM - that doesn't mean the SIM's chip is the problem. Just an indication...
Thanks,
mc

Hi
Please do post the result

I had the same problem (endless reboot) on my Elf. I solved it by replacing the battery.

Hi,
well it's like always. If you need the problem, you cannot reproduce it.
The device wasn't crashing even once on the weekend.. Either with my own SIM or with another one.
The battery thing is interesting. As soon, as the problems start reoccurring, I've got now a spare SIM card to test. If this fails, I'm able to test with another battery in march.
I'll post any results.
thanks,
mc

I have the same problem...and also struggles to find a signal. Did you solve the problem yet?

same problem
I have the same problem and !!!!!!!!!!!!!!!!!

well, the thing is i upgraded to the HD2 and didn't use my elf pretty much lately.
I changed my provider and got a new SIM but that didn't solve the issue. So I can exclude the fault being in the ROM or the SIM card.
When the elf was crashing I couldn't start it up. It was booting, and as soon as it tried to register itself in the Network, it crashed again. However, when connecting it to a power source (charger or pc) and booting it up, it went fine through and was able to register in the network.
That brings me to the idea, the even if the battery is full at 100% it might have a flaw and doesn't bring enough energy, when the device is scanning for the available networks.
So next time, I'm in china, I'll get a new battery pack for my elf - however, it's no more that important as my HD2 is running pretty fine.
Hope it's something which can help you.
cheers,
mc

Phone Constantly is losing Signal

Hey guys i have had some issues with my cell phone lately (hd2 tmous).
3-4 times a day i lose my signal completely and the only way to get it back is to restart the device. Sometimes my device even displays
I have tried using different radios as well no luck
that the simcard has been removed, i have tried everything
also it happens whether im at home, school or work, i live in an area that gets great reception so that should not be the problem.
messing with the band to keep it at gsm only
reverted back to auto
removed and replaced sim card
hard reset, new rom, stock rom, i always task29 before new rom as well
does this happen to anyone else, any ideas on what the problem may be?

A factory reset with formatting the memory is on the cards I think

i just received a new sd card and it used to happen with my old formatted one, im not sure that would work? although it wouldnt hurt to see if it happens without the sd card in it.

It happens to me. Maybe a few times a week, though it will regain signal after a minute or few minutes. Sometimes I toggle the phone option off/on. Maybe that helps or maybe not. Rarely do I have to power down the phone, though I have done it a couple of time when I'm in a hurry.
It used to happen more often with the stock ROM from April of this year. Since I've upgraded a couple of times, it's gotten better. Hopefully the latest 3.14 ROM has fixed it some more.

have you complained to tmobile??? Maybe you need a new phone.

Browsing between topics of the H2 this one came to my attention.
I have exact the same issue! I also had it with my htc diamond. I moth ago when I received my HD2 (non branded) I thought it would be over. But no. it keeps losing signal. Freakingly annoying. I called tmobile (Netherlands sins i am from the Netherlands) and they would send me kindly enough a new sim.
But still…. The same issue.
I also did a hard reset, new ROM (cant go back to 1.33) and tried another phone. I gather it is a htc issue and some bad luck.
I didn’t had the error sim removed.

ok so i went about half a day with the sd card out and when i woke up this morning no signal again.
I gave t-mobile a call and explained to them what was going on. I was transferred to a pda/smartphone specialist, although i would say that any xda community member was more knowoledgeable than this rep. Anyway she asked me a couple of questions said there were no known issues and that i will receive a replacement phone and sim in 7 days and to return the old one phone. Hopefully with the new phone and sim i wont have this issue, im guessing they think its a hardware related problem. It bugs me that cheap crappy phones have no problem holding a signal and my top of the line hd2 does but lets hope had a faulty connection or something.

Your problem (most likely) lies with a bad combination of Rom and Radio.
I know you have tried several radios, but you simply missed the compatible one.

see my posts in that thread.
apart from my provider having problems every now and then, I have not lost my connection again after flashing the right Radio.

i have tried both the 2.13 stock rom radio and then the stock 3.14 combo both did not work.

resolved
received the new phone 3 days ago, so far have not lost service. It must have been a hardware issue with my phone. im using the same radio rom as the old phone except no signal loss, for anyone who is having the issue it may be worth calling tmobile to exchange your phone for a new/refurbished one.

[Q] NAND Random reboots??

Am I the only one who get random reboot every now and then. Typically those happens when phone is stand-by mode. And when it happens then it normally reboots 2-3 times and after that it is stable again... Is there any way to avoid them??
I've tried at least 6-7 different ROMs and this happens with every of them...
And I have done task29 and so on and without task29 and so on.... Damn, this is frustrating...
Now at the moment I am quite happy... only 2-4 reboots per day with version [Feb 02][DL DesireZ v3.4][DL Data2SD/Ext4 v2.7][Nand/SD/MAGLAR]

this can actually be caused because of some gps problems.. I dont think the problem is with your phone.. It's with the ROM i think..
you can try one of the gingerbread roms ? i haven't had any reboot problems running gingerbread.

The only time I've had reboots is when using setcpu - and undervolting the phone too much. If you use setcpu, try raising the min and max slightly to see if it helps.

i got the same issue :/
the phone randomly reboots... i tried different radios and roms but makes no difference.
But since Mgdlr 1.13 i just got one reboot last 24h with latest radio + gpc ginger v1.5
Are there logs at the android system to post here?

provider?
I have the random reboots since i've switched to a mvlo virtual provider in austria (bob). maybe there is a problem with the radio? i get NO reboots in flightmode

@artn3r: hi, same problem here! i'm also on bob.at and i had random reboots with any android build i've tested so far.
but with the hint of an other boardmember i didn't have any reboots since 2 days. i just switched the network mode from "automatic" to "wcdma only".
maybe this is a possibilty for some of you dev's out there to fix that problem!?

Thanks, i'll try!!!

thank's. i'll try it

but this is not a good option, because if the reception is bad, you get no calls at all

sorry guys......
1 hour ago i had the last reboot. so this is not the reason for these f....... reboots.

This text already exists in an another topic, but since this topic is dedicated to this problem, I decided to copy it here as well.
I MIGHT have found a solution to this problem!
Here's a little story about my HD2:
I bought my device about a year ago. The device was equipped with stock Winmo 6.5 with WWE 1.66 (sadly I don't remember the radio number). No problems with it. After a while, I decided update to the latest stock ROM WWE 3.14 (radio 2.15.50.14). Everything worked fine, exept I started having random reboots on idle. The phone didn't reboot on use, only in idle (sleep mode). It could stay on as long as 4-10 hours, or as little as few minutes.
I started to look solution to this problem, but couldn't find it. Then I decided to get a custom ROM, which was one of the Artemis builds. The rebooting issue vanished.
Couple of days ago, I decided swith to nand Android ("Stock" NAND Android ROM). Everything worked very well, exept the rebooting problem came back. I tried different Android versions, radio versions and everything else. Nothing worked.
Now we get to the part which could fix this problem once and for all. Not only in different Android builds, but also in Winmo 6.5 and possibly in WP7.
The solution is to change the automatic network selection to manual! Since there is no clear manual selection in Android, you have to go to settings and manually select the preferred network from the list. I don't know if this is the permanent solution, because it's impossible to choose one and only network, but as long as the reception is good and you don't reboot your device, it should work. I haven't tested if the manual selection disables when rebooting the device. However you can always manually select the network and by doing this you should avoid random reboots on idle.
So the problem shouldn't be in your device, memory card or your custom ROM. The problem is somehow related to the automatic network selection. The actual problem could be in the sim card, or your service provider, or even in the ROM, but you can fix this by manually selecting the network.
This fix also worked with the stock Winmo 6.5 with WWE 3.14 (radio 2.15.50.14) where I had these same problems in the past.
I have now used the HD2 for three days without rebooting. I hope it works for everyone else as well.

I definetly need to test this... And it is so easy Just put pin code asking back ;=)

me too... same problem here

Report me back, if this fix worked, because it gives me some reassurance that my phone is going to work in the future, without the annoying reboots.
Four days without rebooting. Fingers crossed.

Moro! Itse olen käyttänyt HD2:sella Rafdroid HD:tä versioita 1.0, 2.0-2.4 ja 3.0 ja kaikissa on ollut tää inhottava random-boot hommeli.. pitääkin testata jos tuo manual network selection auttaa asiaa, kiitos vinkistä
Hello! I've been using Rafdroid HD:s all versions in my HD2 and always I have random booting.. I should test if that manual network selection helps, thanks for advice!

The couse
I think I know what couses the reboots on my phone.
The reboots only happen when i am on 3G. I know this becouse when im at home i dont have 3g but at work i have 3g. And reboots only happen when im at work.
Anyone that can confirm this?

The reason why you are experiencing random reboots, might be caused by your service provider. Because many people here in Finland, who have service provider called "Saunalahti", have the random reboot issue, when using the automatic network selection. However, when I use a different service provider, I don't have these issues. This is also the reason, why we are not all suffering from the same problem.
I have now switched to nand RAFDROID 3.0 and immeaditly turned of the automatic network selection and I haven't had any rebooting problems. So it seems that at least for some of us, turning of the automatic network selection will resolve the random reboot problem.

Thanks, I am going to try this. My phone has a tendancy to reboot everytime I am in the UK. In my own country, Holland, I don't seem to have this problem as much, only once a week maybe. This seems to support the theory mentioned above.
Thanks again.

i had same prob
i've had the same problems on my hd2, only it didn't reset on idle. i've send it to te factory, for waranty. luckely i stil was on winmo 6.5.
3 weeks later i've got it back with new mainbord and battery and now it works fine

Hello all, i seem to be suffering the same reboot problems. Been running NAND android since it came out with no problems. Now i get random reboots.
Where do i go to change the network selection to manual? is it in *#*#4636#*#*
Thanks!

another annoying "my hd2 running wp7 keeps rebooting!" thread

Yes, this is another one of those annoying "reboot" threads. My HD2 has had lots of problems trying to run WP7. I've had multiple reboots during multiple tasks. It made the phone unusable for a bit.
I finally have a stable ROM that at least allows me to make calls and use the phone - as long as I don't try to access the Internet more than a minute or so. If I access the Internet for more than that minute or so I end up stuck in a reboot loop.
Removing the battery, waiting for a few minutes, and replacing the battery and rebooting the phone solves the reboot loop issue.
I don't know if it's the radio itself, or the particular radio version I am using, that is causing the problem. Calls are not a problem, as I mentioned. I really enjoy WP7, and would like to be able to fully enjoy it without experiencing this dodgy Internet access experience.
FWIW, I have tried several different sd cards, which I know have been identified as being the culprit in a massive number of cases, but nonetheless experience this same problem.
Cheers,
Bubba

As of right now only ATT carries windows phone compatable sd cards. I know because im using one as i type this message to you. Since i purchased it I havent had one single reboot. They only sell them in 8gb/$32.00. Hope this helps. WINDOWS PHONE 7 KICKS A** WHEN FULLY FUNCTIONING

Missing calls with official 2.3.5

Hello everyone;
I flashed the latest official 2.3.5 last night. Missed three calls afterwards, as if I was not connected to GSM network. I was at home and signal was stable as usual. Anyone else noted unusual GSM behaviour?
Cheers
----------------------------------------
UPDATE: In order to better understand this issue, it could be interesting to know which service providers are being used; in my case, TMN in Portugal.
One week before flashing this ROM, I started using 3G, so I'm not sure if these missing calls are as result of the ROM change. I'm going to switch back to 2G for daily use and see how it goes.

Yes, if you search you will find other users with the same problem.
happens also with the other beta roms.
Sent from my U8800 using XDA App

It happens to me too unfortunately.. can't tell the reason why. GSM status seems ok.

I confirm this missing call issue.
People when ring me the first time they go straight to voicemail and only get connection on second try.
I think the only way to solve it is Huawei but there is not point of trying to speak to them and they just won't listen for what people say to them.

I can confirm this is happening to me too....after reporting all was well this was one of the things I didn't test out.
Weird thing is that I called my mobile from home and both went straight to voicemail...

yep.
but if you immediatly make a 2nd attempt you get connection

OK try this...
Turn off phone... re move battery and sim card.
Replace battery and start phone without sim card and boot up.
Unlock phone and open any app (doesn't matter just do something)
Turn off, remove battery, replace sim.... boot up again.
Just called from my wifes mobile phone and my phone rang OK.... will test further but that seems to have done the trick for now.

I got the same problem and so far nothing i did solve it... Just missing reinstall the rom again and see if wasnt any bug i got while installing... I don't see too many ppl with the same problem and i don't belive huawei had so many diferent hardwares in a single mobile phone model according with all the different ppl have with different phones.

I also have this problem with the new firmware. My phone doesn't connect to the network upon powering on.
I have to manually connect it, by going into the Mobile networks settings. Once i'm in that menu, it connects.

druida_69,
I can confirm that does not happens every time, I tested from other phone I only on the sixth call I got the ring... Worst, during this time I made a call without problems.
The question is on reception...
Sent from my U8800 using XDA App

this issue is killing me.
when I have the device disconnected or in a cal, when someone try to ring me and can't I always receive a message informing that the xxxx number tried to ring you at that time bla bla bla.

no calls
The same thing happened to me... also tried many things without success... downgraded to 2.2.2 (B138) problem solved...
I'm getting tired of huawei's poor support and buggy updates!!!

To be honest i don't know if this start to happen after or before installing geno‘s OC Kernel.
I can confirm that this happens when the phone stays for a long time inactive. Try not playing with you're phone gore 20 minutes or so and then try to ring youselves.
Its like if the phone entering in a zen deep sleep....

Same here
Started after updating to 2.3.5, anyone tried the updated 2.3.5 from Huawei? it removes the pink screen I heard, but maybe it fixes this issue

F****** Huawei. Just realised that I have this bug too with latest 2.3.5 release... I think that it's data dependent. If you turn them off it connects ok...

I didn't realize until I read this thread, but I have the same problem!
I'm over it, I'm going back to Oxygen until I can buy a new phone, and will probably never buy huawei again.

I had this problem initially but since I booted up without sim card and boot up again with it in hasn't been a problem...I've had to test this on a few different phones & reboots now and everything is fine....
