[Q] Failure to start external modem? - One (M7) Q&A, Help & Troubleshooting

Hi everyone,
I have encountered a really annoying issue with my HTC One. It is a completely new replacement unit, and ever since I started using it I've had problems with the reception. In the beginning it only lost reception for a short while, and then regained it. Now however, the loss of reception is almost always followed by an immediate reboot, and after this reboot the phone often will not allow me to enter any pin at all. It will just show a "no reception" symbol in the status bar and subsequently reboot again after a minute or so. This boot loop continues until the phone actually allows me to input the pin again, after this the phone will work fine for awhile until this looping business starts anew.
I've actually tried a whole lot of different roms and radio versions in order to try to solve this issue, but to no avail. I've also used an RUU to reset my phones firmware from the very beginning, but the problem still remains. I've also tried to swap sim cards, no luck with that either.
I've tried to check the logs after these reboots, and the only things that seem to have anything to do with this are the lines: "failure to start external modem" and "MDM common shutdown".
Am I out of luck here? Is there anything I can do in order to try to fix this myself?
I'm afraid that if I hand it in for repairs the shop won't actually experience anything wrong with it, since this happens so randomly, and just send it back to me with a service fee.
Help is much appreciated!

Anyone? I've made a logcat log of the error tagged-messages that occurs right before a restart:

[Q] Anyone have a problem getting their HD7 to reboot?

Upon rebooting of my HD7, many times it will show the HTC logo, then go straight to a screen showing the device being plugged into a pc. It will continue to do this regardless of how many times I reboot. The only way out of it is to reboot into the bootloader by pressing power and volume down, and then rebooting from there. Ive tried to plug it into a pc and let the zune software reflash the whole thing, but it complains that there was a problem with the restore... and when I do get it to reboot, there are NO probelms at all! (Besides the memory problem with The Harvest crashing out to the tiles like everyone else it seems). Has anyone else had this problem? Weird thing is, the first phone the TMobile sales rep brought out did the same thing! I wonder if its some kind of problem with the actual bootloader?
Had the same issue.

I'm guessing there was a bad batch somewhere, a very limited batch as you're the only other person I've seen say this
FYI. I've had this happen too. I had to pull the battery to get it fixed.
Sent from my HD7 using Board Express
Same problem, if the phone dies and you turn it back on you get "connect your phone to computer" screen (and the phone loops turning off then back on to the same screen, and then repeats); and if you manually turn the phone on and then back on you get "connect your phone to computer" screen as well.
Battery pull is the only fix at this point. I haven't seen much of this problem either, if i find out its a hardware issue i'm getting mine swapped out ASAP.
I had similar issue just downgraded it to nodo using goldcard and the issue resolved.
Cheers.

StkAppService - com.android.stk restart loop?

Hello people, first post
I have this little problem that's been bothering me with my new O2X.
When restarting my phone, the SIM Toolkit service, StkAppService - com.android.stk, pops up in service manager, and seem to be running fine. After a while though, the service seem to get stuck on "restarting".
Haven't quite been able to lock down when/why. Seems to be connected to extended periods in sleep, or playing games, but this could be just random.
When shutting down the service manually, everything seems to be just fine, and it won't come back until I for some reason restart the phone again, then it it'll be back to working fine, and after a while stuck on "restarting" again.
Is this something I should care about at all? Just seems to me that having something stuck in a restart loop (could just take a really long time, not 100% sure it's actually looping yet) would drain my battery.
So, to the point. Could this be a fault of the phone itself (making it a warranty case), a bug with Android 2.2 (wait for 2.3) or an issue with my service proivider (in witch case I'll contact them)?.
Been unable to find the answer on my own, and this is my first Android-phone, so I consult you, the wizards.
Update:
Checked with a friend of mine who bought the O2X at the same time as me, and he also has StkAppService stuck on 'restarting'.
And the phone glitched out and refused to fall asleep by itself today. Restart fixed it though, haven't happened again.
Another Problem with STK
My problem with STK is another one:
I have two SIM-Cards installed in a dual-SIM-Card adapter. So with stock ROM switching between both cards via STK works fine.
Now I tried several CM7-based ROMs, but with all ROMs I receive the following error massage when switching to the other SIM (translated from German to English):
We are sorry! The process com.android.phone has been unexpectedly terminated. Pleas try again later.
After that, I can enter the PIN-code of my SIM and it is activated. I´m not able to switch back, when I tap on the app-icon it switches back to home-screen.
Any solution for that? (sorry for my bad English...)
Hi,
two years alter, I am facing the same issue, and XDA developers apparently are not working on including proper STKs with custon 4+ Android Roms.
It's a pity

[Q] razr i stock 4.1.2 random crashes, logfiles needed

good day fellow razr i owners,
my razor i (91.2.26001.XT890.Retail.en.EU) is behaving very strangely since it got it back from support with a new mainboard. Sometimes it just freezes or crashes, and when I reset it, it's often bootlooping around the flashing M-Symbol with a little clicking sound everytime it starts over. I can get it to boot up if I keep resetting it, shutting it down, starting it again aso. I can get into fastboot and even then it's not certain that it boots up afterwards. I managed to get into recovery mode with a process log that started to overlap the lines of text. Sadly I can't manage to get that again for further troubleshooting.
The easiest thing would be to send it in, but I've already done that only to get it back with the comment "couldn't reproduce the problem, upgraded the firmware".
Since then I try to reproduce the crashes so that I can proof the defect even to a service team that starts it up, sees it works, shuts it down, flashing it and sending it back...
Crashes and/or Freezes can appear when I'm handling it or not. When I'm browsing with Chrome, using the camera, use Google Now, play Simpsons Springfield...
Sometimes background processes stop to react spamming me with messages like "the process com.google.process.gapps isn't answering" -> OK (translated from german)
Since these problems started after a motherboard change after a brick (downgrading from 4.1.2 to 4.0.4) I'm thinking it's a hardware problem.
I tried to create a logfile with adb shell dmesg > log but only got "klogctl: Operation not permitted"
It seems to start more reliable when not used for a while after a crash (cache clearing?) and it seems to crash more often when plugged in
factory reset seems to work for a while but after 2 days at most it keeps crashing/freezing again
I would love a fix for the phone, but I don't think there is much I can do when it's really a hardware problem so next best thing would be a way to get a error log, that I can send the support with my device as proof that there is a problem and all that obviously without voiding the warranty...
Thanks in advance for any help

[Q] Radio shuts off for ten seconds after every call

I'm running 4.3 rooted on ML2, stock ROM. Within the last week I started experiencing a strange problem - after every single phone call made or received, I lose all network connection for about ten seconds. I get the circle with the line through it. Going into settings shows actual connection drop, not just the icon. Then, the connection reappears. I've made no modifications since rooting it in April, nor do I recall removing or freezing any apps any time recently. Powering down and/or removing the battery has done nothing to help.
Any ideas what would cause this? I can't find any threads here, or through a google search, discussing this problem. Any help is appreciated.
Update - same problems when running in safe mode.
Well, this seems to have been a local network problem, as the issue has magically disappeared. Nothing exciting to report.

Remove SIM card and clean?
Yep - did every trick in the book. Even reflashed via Odin to be sure I didn't have a corrupted radio file. It just started working again. I"ve seen the same problem reported in other parts of the country, apparently the result of something AT&T was doing to the network.

Freezes and restart... Died. What is the problem?

Hi guys since yesterday I have problems with my phone
the phone suddenly freezes over without being able to interact.
it restarts on its own but without ever starting the operating system in fact it shuts down and does not turn on again as if the phone had died.
the really strange thing is that the phone was fine Then suddenly he started making this mess.
Yesterday after so many hours of problems I managed to start the phone and now it works well but I am afraid that the situation will repeat itself.
the phone has the bootloader unlocked has root permissions, I followed the guides on this site.
But I have had this phone for two months now and these problems never occurred.
where can i start to understand what the problem is?
Mine suddently become all white, with the interface cut in half and moved up. i could do nothing. nor reboot nor shutdown.
after some minutes it turned back normal. i hope its color os bug and realme will fix it
It appears to be a firmware problem. We hope well.
Today did not give problems. This behavior is really strange, what can I install to understand the root of the problem?
I noticed that if the phone never goes into deep sleep mode the problem does not occur.
Now I am registering the log and as soon as the problem occurs again I go into detail to find out the real reason.
I'm trying to create an automatic script that is launched on the boot that practically never makes the phone sleep.
i'm really desperate the phone started to reboot itself.
I would like to try using a system log recorder but I realized that when I restart the phone these logs are not saved so it is impossible for me to verify the reason.
Can any of you help me out?
the phone freezes and then restarts.
Did you achieve any solution ?
No. I'm disperate.
Why don't you flash stock fw /recovery? Just to make sure it isn't an Hardware problem ?
I try but have this problem

@westenlive
The problem appears only when you use data connection right?
If you try to switch off data and use wifi , you will not notice
The problem is because of the the operator, try another sim provider
Yes, in fact, that could be the problem because a few months ago removing the SIM card the phone did not give more problems
maybe you gave me the solution. I'll try

I am now testing the LINEAGE it happened to me this I removed the SIM card and I installed the costum Rom, I made the various customizations and the phone never locked OR restarted.
I inserted the SIM card in the phone worked perfectly, then having messed up with luckypatcher I had to reinstall the Rom.
So I performed the same procedure with the SIM card inserted in the phone and already at the first start it was unstable with reboots.
Currently I have applied for a change of sim card.
As soon as it arrives I will try to remove the sim card Install from scratch The system is to insert the new SIM card only so I can have the mathematical certainty that it is the SIM card
I hope my experience can help someone
This problem seems true, my X2 Pro also faced same issue when enabling cellular data. The phone sometimes loses the signal or the app freezes and perform a phone reboot. X2 Pro is a mid-range flagship phone, and yet this problem should be solved before they start to sell the phone.
Yes this device has many software problems but hardware problems of this kind are not acceptable.
Practically mine has become unusable, as soon as I turn it on after a few minutes of use it start closing the apps by itself.
Then after AN intende use of 30 minutes it start to restart.
This phone is truly incredible
Next time buy ONE PLUS
