hello together,
my beloved HD2 (EU Model) is subject to random (daily) reboots, no matter what kind of ROM I've installed (2.3.3, 2.3.5, 2.3.7, 4.0.4, w/Sense, nonSense). This morning I catched it rebooting. When I tried to wake it up (PowerButton), the ScreenSaver appeared, I unlocked the device, then it freezed, and after a couple of seconds it rebooted.
No I have attached my actual CATLOG. Any idea on what the reason could be??
I'm currently on the latest Energy (2.3.5, Sense 3.5) Build, with 5/200/5 layout and a 16GB SD-Card with 1GB SD-EXT.
Any help is much appreciated! Thanks a lot!

Hardware problem means? Memory (RAM) physically damaged? Have you ever had a similar problem?

Sorry couldn't stop myself.. Have a nice day
btw your logcat is clean, nothing wrong about hardware or anything about reboots..
could be bad blocks, boot your phone into the tri-color screen, attach the usb cable and ensure you have the "old" usb driver installed, you will find it on the definitive mtty thread for HD2, launch mtty, select usb in connection and press ok, a prompt comes up, type "info 8" without quotes (press enter ofcourse) and post the output here.
Oh, this is wrong section btw, thread reported.
Hello Rick, since I'm working with the same SDHC for at least 2 years, without formatting at any point, but with a lot of changes from ROM to ROM, I decided to reformat de SC-Card completely (with SD Formatter), and then install the ROM up from the scratch. Good or bad idea?

Hi Rick,
what does "Failed to find cpu subsys" mean? Nothing serious?
SIM Card related problem
Hello everybody,
Well...I'm suffering from the same problem you all are talking about here, random reboots (even in stand by).
I was researching here in xda, about this problem, and there's a lot of possible causes of this issue:
Overheating
Bad NAND Blocks
Motherboard soldering problems
Related problems with service provider signal and SIM Card
I can tell you that I suffer from overheating (playing games, youtube, browser, the back case gets very hot), and Bad NAND blocks (2 on boot partition, 1 on system and 2 on userdata) but it seems that's not the problem (for me).
I live in Chile and I have a T-MOUS (1700/2100 for HSDPA), I used to use it with movistar (850/1900) SIM Card for the last 5 months, but with no data plan due to the fact I could not use 3G here for bands incompatibility. I recently switched from provider, to Nextel (1700/2100), and voala, 3G started to work, and in the same time, problems with freezing, random reboots, high battery drain, etc...
I've tried a lot of solutions, like turn off automatic time and zone, auto backlight, manual network selection, etc, but none of these worked out. I was about to resign when I switched sim cards with my girldfriend for an experiment of signal-loss during one night, and the HD2 (with movistar and NO 3G) started to work again with no reboots, normal battery drain, etc...
For me the problem is the 3G data connection (I use ICS ROM from tytung, with RMNET, i tried PPP but I lose connectivity, no 3G). I don't know if theres a problem with the 3G itself or if the signal carries something that causes all the problems (I reed somewhere that T-Mobile once changed something in their signal and problems started to appear). I wish I could try another 3G provider, but here Nextel is the only one for my T-MOUS that opperates in the bands I need, so there remains the question.
Now I'm registered in another network (Nextel R), that is their 2G network, and I've data connection via EDGE, and it's working flawless as expected. I don't know if there's a fix for this problem or if I've to resign.
tom2lee, can you post your actual network situation and datablan etc, so I can compare the case with mine, maybe we can help each other.
Thanks
Hi Zaidor,
thanks for your descriptions! I'm living in switzerland, which is a very small country in the midst of europe (north of italy and south of germany). We only have 3 network carriers, where two of them are sharing the same infrastructure. I'm personally registered at the "Sunrise" network (www.sunrise.ch). This carrier offers the same network options as "Swisscom Mobile", the #1 carrier here in Switzerland. Depending on pricing plan you can have anything up to UMTS performance. For me, with a quite cheap plan, there's only remaining GPRS/Edge, which is enough for my daily sync needs. For the rest I'm sporting a fast W-LAN at home and at business site.
I also tried nearly every type of ROM, and I'm sure the problems wheren't there with the old froyo roms, some years ago...
But anyway, I'm now living with that I think, due to the lack of alternatives.
Be blessed!
Tom
Have u tried with a different CPU governor and a higher minimum cpu freq?
I use tytung ICS v2.5 rom, with PERFORMANCE governor, minimum 576mhz and maximum 998mhz...works, no freezes.
Try and give me some feedback
thanks
Hi,
I have also some reboot with my HD2. What's the probleme?
I used the NexusHD2-JellyBean-4.1.2-CM10 V1.3a.
Thanks,
I own a Verizon Motorola Razr M, bought in ebay to an US seller. I am in Spain and I use Movistar SIM card
The phone came with stock JB 4.1.2, and therefore I could not unlock the bootloader.
I started using it, but it had a problem that I am not been able to solve so far: after some hours of use, with no problems with GSM and data connections, it suddenly looses both connections, although the signals on the status bar still appear. I take care that signals have gone when I take the phone to make a call or surf the web.
I have tried the following procedures:
Change the net settings to GSM/UMTS
I rooted the phone with motochopper 1.1.2 exploit
I installed Safestrap 3.12 in order to be able to install other available locked compatible roms.
I tried these roms, following this thread here in XDA: Clean ROM 1.0. Clean ROM 1.1, Barebone New Base, Stock Deodexed.SDswap-Locked & UnLocked BLs-xt907-9.8.1Q-94-1, but no luck. This last one uses the last radio, but no way.
I also installed the [PATCH][GUIDE] Patch to fully enable GSM on Verizon CDMA Android phones. I could only install it on Clean ROM 1.1 however. It has been impossible to install it on the other ROMS. In any case, no luck again with the patch installed. Here I had a big problem because as I still had these problems, I got into *#*#4636#*#* in the dialer, and touched the band selection option: suddenly, the net showed no signal more and I was unable to make it work again: I finally solved this by installing the stock firmware from here with RSD lite.
No way. I still have this problem and I can not use the phone. I have also tried with another SIM card, but the problem remains. It is a shame because when the connection works, the phone runs very well.
Any help would be very appreciated

The problem also seems to become worse with the use of the phone: at the beginning, coming from a factory reset, It can last some hours before the problem occurs. But since it happens from the first time, it happens more and more frequently and the phone can not be used any more. It seems that there could be a software issue.
Another try disabling fast dormancy
I´ve just disabled fast dormancy, because my operator Movistar apparently does not use this technology.
For this, I have modified 3 lines from build.prop system file, as indicated in another site.
The 3 lines are:
ro.mot.ds.fastdormancy.disable=true
telephony.lteOnCdmaDevice=0
ro.telephony.default_network=3
Having fast dormancy enabled when your operator does not support it, seems to drain battery, and could cause other problems. That´s why I´ve done this. I have used root explorer apk from Google store, it is free and it automatically creates a backup of build.prop file when you modify it.
I keep the fingers crossed, let´s see what happens.
Fast dormancy: yes but...
After some days using the phone with fast dormancy disabled (for this, I also added this line to build.prop: ro.ril.fast.dormancy.rule=0 ; I read this for ICS Roms, I do not know if this command is also valid for JB, any comment will be welcome), I still get some cuts (less I would say), but at least the phone tries to restart the connections. For this, I have also installed the apk from Google Play called 3g reconnect.
In any case, any comment would be appreciated.
Issue not solved
I still get data and voice disconnections when I use GSM/UMTS or only UMTS modes. They occur ransomly, and they also occur as soon as I use a WIFI connection. I can only use the phone on GSM only mode, which is frustrating.
Any advise?

I do not go near *#*#4636#*#* anymore. So tell me do you use that to make these changes (phone info is the app name).

Hello,
I have tried both: using *#*#4636#*#* or using the usual phone settings. Sometimes I have also checked that the changes made with the usual settings appeared also dialing *#*#4636#*#*.
Yesterday evening, I tried selecting global mode instead of GSM/UMTS and it seemed to work for some hours, but today morming, the problem occured again. So far, the unique way I have found to avoid connection cuts off is using GSM ONLY mode. I have to say that I have tried with 2 different SIM cards but the result is identical.

Did you select the 3 dot menu & mess with the "band" settings?
---------- Post added at 07:08 AM ---------- Previous post was at 06:56 AM ----------

I did that once, and all the signals disappeared. I restored the phone with RSD Lite, that appeared to be the unique way to have again signals working. Now I do not even dare touching these 3 dots.

What booby a trap? How many step into!
I don´t know if I am understanding you. I did that once because I did not know what else should I do to solve the problem. I saw that there was the possibility to choose theoritically between US bands and Cellular, and I entered in that menu. It is not so stupid to try that if you have already tried 100 other ways.
In any case, anybody has an idea about how to solve this problem? I´m sure I am not the unique person having this issue with this phone.

You are saying the problem is now still there. Yet the radio partition is fixed. Please restate what has been fixed with the rsd flash & what remains unfixed.
Well I think I have fixed and solved the problem: I initially copied the APN settings I had with my previous HTC Sensation, because the phone operator was the same (MOVISTAR), the SIM card too, and I have not moved. In these APN settings, the proxy was "undefined" as well as the proxy gate. I wonder if the radio stucks looking for a proxy each time or whatever. I tried yesterday with completely different APN settings, with a concrete Proxy and a gate... and now I have not had any issue in the past 24 hours. I will still wait a couple of days to see if that was finally the reason.
Which in any case would be silly, because I just applied what was working OK with my sensation, but...
New APN settings: let´s see

After several days, the problem is still there. After setting new values in APN, it happens less often, but it still happens. I have to switch to GSM only mode.
2 days ago, I was surfing the net at quite high speed with no interruptions, for half an hour. I then shutted off the screen, on again some seconds later, and the connection was blocked, I had to restart the phone. It has to be a software issue.
I finally sold the phone
After concluding that I could never get rid of this problem, I sold the phone, informing that he would have to use mainly GSM only connection. Great phone otherwise, but with this issue.
This sounds like a Baseband Issue.
Europe I have found baseband:
sm_bp_101031.027.32.81P to be the most stable so far, with no H+ support though.
But most Carriers in Europe don't have H+ or LTE.
That baseband is part of build 9.8.1Q-66
Which can be all downloaded here:
http://sbf.droid-developers.org/phone.php?device=8
The baseband from 98.16.1 had H+ support in Europe but connections dropped like crazy.
Same with 98.12.4, we remedied that with Aussie Radio at the time.
Maybe this may help some International users with Data and GSM Loss

I'm on 9.8.1Q-94-1(98.30.1.XT907.Verizon.en.US) and wanna use it in Germany. any experiences with the radio compared to the suggested one. Or is there another way to boost the performance of the razr m? Compared to my razr I the signal and data quality is really poor...
edit: my baseband-version is: SM_BP_101032.021.32.80P
edit2: ok... now i've flashed several basebands... and the behaviour of the phone is always the same... with the australian baseband of xt905 it wasn't possible to get an hspa-connection. dunno if its enough just to flash the radio-fw?!?!?
so is there an other way to get more stability in my region? i tried to flash the radio from razr hd retail germany. but i think the razr m don't like it when I fool around. actually I love the mobile, so i don't want to make it angry... your suggestions are very much appreciated...
I've got some problems with mobile data on my Note 4. I've bought unbranded phone in shop unrelated to any mobile provider. It's Snapdragon version (N910F).
I've got prepaid service, without LTE available (if that's important). The problem is that every now and then mobile data simply stops. There is still H or H+ sign in notification bar, and upload arrow blinks. but when i try to open web page or send message through viber, wattsup it acts like there is no network. Then i have to wait for about 30 seconds or manually turn mobile data off and then on again for internet to start working again.
I've tried changing APN settings, changing network type, but the problem is still there.
I've read some similar issues with Note 3 and SGS5 users, and some problems with modem versions, but i couldn't find anything from note 4 users
And this problem is very frustrating on phone like Note 4
Is there anything else i could try?
Mate i have exact same problem
I don't know if this is relevant, if your apn settings has a proxy and port values, try to delete it and let the proxy and port be blank. I had issues previously with data getting stuck while using proxy setting.

I also loose data signal and on calls people cant hear me properly.. doesny always happen. Ill try thanks
Also experiencing this with Tmobile UK.
Also have this exact same problem with the unbranded SM-N910H, H+ but no internet all of a sudden. I also sometimes lose the whole signal (Emergency Calls Only) so I have to reboot or turn airplane mode off and on to get it working again. I asked some people and they told me it's a coverage problem with the network provider. IDK if it's true.
No ahmadmob its the phone although i have n910u i have exact same problems as u!! I thinks its modem hopefully gets solved soon im in Australia using prepaid only 3g/h+

Glad it's not a carrier specific issue.
Guess I'll wait for an official fix or for other radios to become available.
I rang samsung australia few weeks ago and they had no idea than again when do they ever!? Lol so looks like we will have to wait buddy
Some common suggestions:
1- Swap the SIM card into another phone to see if the problem persists?
2- If the problem is due to Note 4, you may need to update your firmware/baseband to the latest one (if one is available, or you have to wait until Samsung release it), or try another firmware (from another model) or custom ROM.
Tried already mate sims fine updated reflashed stock rom and still same problem.. hopedully update comes soon
I just tried sim card from another carrier, and for now, everything looks fine.
I'll go ask for a new sim from my carrier, or switch my number to another one.
Sorry for digging, didn't want to make a new topic.
I'm here with the same problem. Did any of you find solution for it (other than switching to different carrier). I'm on Play in Poland and i find mobile data problematic mostly in roaming (free roaming with every carrier in Poland). For example on t-mobile or plus i find my up arrow constatnly blinking and H switching to H+ and again. Problem is even worse with 2 or less signal bars. I'm thinking of changing sim cars to new one, but on my note 2 everything works perfectly fine.
I thought I noticed a slight improvement after the final KitKat update, may have been a placebo effect though.
In general it's still bad, much worse than my HTC M7, same network, same location etc. It seems to be particularly bad when travelling at speed e.g. on the train I get full bars but only 1 arrow flickering.
Upgraded to Lollipop a couple of days ago and finally rooted, doubt this will make a difference but will be able to report during my commute tomorrow.
In summary: The HSDPA modem on my phone is rubbish.
P.S. Previous phones I've owned came with options for different modems, I'd often flash these to improve performance, where are they for the Note 4?
I think they're not available yet, at least on lollipop...
Mine is completely fixed after a few updates i get 4g+ here excellent reception

Could tell more how did you fix your problem?
All fixed!
I can confirm that after the lollipop 5.0.1 update on my SM-N910H all my mobile data problems/mobile network drop outs are solved!. 3 days without any problems now.
Edit: maybe it had something to do with Radio and it got fixed after it got updated along with the lollipop update package?
Guys, here in my country Bulgaria, many of us owners of SGN4 have the same issue and wilth Lollipop also. I have noticed that with KitKat the problem was more frequent than Lollipop but it is still there. We have tried Polish Lollipop and now the official Bulgarian Lollipop but the problem still exists. I hope somebody will tell me which ROM you have installed (oficial) so I could share it with my fellow citizens. Thank!
I bought a used OnePlus 2, and it seems to be the Chinese version. I'm in Europe.
It's in perfect condition, no scratches or water damage but was sold as faulty as it could not recognise any sim card. The previous owner claims this happened when he updated from one version of Oxygen OS to another stable version of Oxygen OS.
I updated to Oxygen OS 3.0 beta and after some research I went to fastboot mode and erased modemst1, modemst2 and persist. I rebooted and now it found the sim card but the sensors went crazy. I then flashed a new persist.img and the sensors are back to normal.
However half the time there is no network signal and when I get a signal it is very weak. On the few times it connects to mobile internet I can only get 2G. When the icon shows 3G, H, H+, or LTE the internet connection doesn't work at all.
I flashed both stable and beta versions of Oxygen OS but the problem remains. I also played about with the *#*#4636#*#* mode and no band mode worked any better.
Is it a software issue, and if it is how do I fix it?
Or is it a hardware issue and I need a new motherboard? From where do I buy a motherboard? I didn't find one on AliExpress or Ebay.
Thanks!!

i'm also facing same problem, Plz help
I think this problem surfaced ever since i downloaded the beta update for Android 7 on my Nexus 6P device. My signal coverage and internet speed ( LTE/4G/3G) started fluctuating on its own and now the condition is so bad that i haven't found any signal connectivity for the network that i use even though other users of the same network in my area are having connectivity. I tried to insert that sim on another device and it worked just fine. I have taken every measure possible, restarting, doing factory reset, downgrading to Android 6 etc etc, i just wanna confirm if there is something else i could do or giving it to the service centre is the only option left?
I cant even tell if the SIM card slot is broken because the notification bar does not show me the error that the SIM is missing or whatever, it is reading that there is a SIM card there, i'm just not getting the connectivity...
HELP ME! I LOVE MY PHONE WAAY TOO MUCH!! I DONT WANNA LOOSE IT FOR SUCH A LONG DURATION!
