Hello there!
My Defy+ (Motodefy Plus) reboots when initially powered in 10 seconds after the proposition to create a motoblur account right after the moment the Mobile Data Connection is established. I have written a letter to motorola support 3 days ago, all in vain - I have no answer from them on this matter. There is a way to evade the described reboot - skipping the motoblur registration and disabling [Mobile Network Data] setting in [Data delivery] section of [Battery and data manager] settings helps to prevent automatic reboot cycle. Using Motorola's official site recommendations upon this cycle reboot issue, I have done factory wipe&reset and changed my simcard for a new one, I have tried sims from different operators and tried switching on [2G only] and [3G only] modes. None of this actions helped to cure the reboot cycle. BasebandSwitcher was ineffective as well. *#*#INFO#*#* with its selector did not help to solve the problem. I have made log files by CatLog market application, which point to the source of the problem - the MOTOBLUR raising a bp_panic event. I attach the logs to this post.
The firmware is the handtec stock ROM 134.DFP-84. The Baseband is stock EPU93_U_00.5F.00.
Does anyone have the same problem? I have searched the forum and found similar issues handled by basebandSwitcher, sim change and nordic firmware, but they do not work for me.
Any ideas?
I've got the same issue here with Defy+ . It started rebooting just after unboxed.
Enabling the Mobile Network Data will make almost instant reboot. But sometimes it reboots without having mobile data enabled. Have you sorted this out ? It is really annoying.
Did you skip motoblur registration? I am trying to figure out the pattern of the problem's appearance and origins.. With no success.
I think I did skip the motoblur registration, but later on I've registered.
Mine started rebooting a few seconds after a very first boot. It restarted a couple of times in a row and than stayed fairly stable for a bit. Now I can't use mobile data at all, but it sometimes still reboots anyway. Safest option is the airplanemode :/ . Has motorola support replied to your mail ?
Yes, Motorola did reply to my email. Actually, the techsupport asked for my IMEI number in reply to the bug-report similar to the first post of this topic. This fact distressed me a little. I provided the IMEI and have not heard from Motorola since then..
You should consider contacting them as well, otherwise they will not treat the issue as a serial bug. As it appears to be.
Okay, meet the official Motorola reply:
Thank you for contacting Motorola.
In response to your query, our technical team has checked the issue for you, we would recommend you to check the SIM card, try to replace the SIM card, and please make sure that it does not have the code (N5) on it.
The N5 SIM card was used by several network providers in Europe, and it causes the phone to reboot.
If the problem still persists, we are afraid that we would like you to contact the place of purchase as it might be a faulty phone, we do apologize for this inconvenience.

This is some kind of bull****, I bet they did not even bother to look upon the log-file. I have 4 defy+ at my disposal, three of them work well with all kinds of sims available to me. A disclaimer from Motorola, nothing more.
I offered a remote access to usb debugging via "USB over network" to them, but they seem to ignore this proposition.
I sent the RMA form to handtec, waiting for their decision. The preliminary is to replace the phone for a new one. I hoped to solve the problem quicker though. It was excessively self-confident, I suppose.
It is good to know that if your phone has established the mobile data connection even once and successfully transfered any amount of data through it then it is completely free of the discussed bug.
I've contacted motorola support as well, they advised me to check sim card and do the Factory reset which I'd already done before. To the question if they have encountered this issue they replied they haven't had any similar issues that are not linked to either the sim card or the SD card.
I am going to replace my phone.
Anyway is there any stock SBF for defy+ I can use to get to the original firmware as I've also tried some custom roms ? Thanks
Interesting. So, they did not encounter a similar bugreport from me. Tried to report this problem for the second time through the motorola.com support form, but received a reply from the same person (Abdullah) and the same text to check the sim with a "resolved" mark.
Yes, there is an official stock ROM named 134_DFP-10 from clove.

Good luck with the replacement!

So, it is not a MOTOBLUR problem.. Does it mean that we have a buggy hardware?
Thanks for the official SBF.
Well I suppose it is a hardware problem, but I've just tried different nandroid backup versions with motoblur included so far. So it still might be the motoblur or something software related deeper in the system.
After trying MIUI I can't boot up the phone at all that's why I wanted the stock SBF. A new phone is on the way so I just need to get it how it was and try a new one. I'll let you know if the replacement is working fine or not.
What is your serial number? Mine is M776QS6VFV. I wonder if they are from the same consignment. China TianJin, 2011 September.
Mine is M776QU2L4S. After flasing shadow_2.3.4-134_DFP-10 it worked much better than before, but it still reboots occasionally, but now it is able to establish data connection and download some data.
Anyway the replacement works fine. Software version is identical to the first one.
i was thinking to buy defy+ m from india. should i go for it ?
Definitely yes
Phew, I'm glad I'm not alone , after flashing a custom rom straight away, the phone did reboots with 3G enabled, I was going nuts! I tried baseband changer, every ROM flashable. Currently running CEE SBF 2.3.5, 2G works but reboots from time to time. Eagerly waiting for a solution, will try new SIM, shutupbattery app (possibility of phone rebooting due to low signal). Hope we will find a solution soon!
Had the same problem.
ItS a hardware fault.
I took mine back and got a new one and now its all WORKING!!!

Yep, I thought so and have sent mine back to the store today. Hope soon will get back a new one that'll be all working)
I purchased Defy+ 20 days ago and really like the phone a lot except for the bizzare problem which many have pointed out. the phone reboots at random in middle of conversations or while accessing data through mobile network or while I'm present in area with extremely low network signal.
I suppose these problems are not specific to motorola products only. I've heard many other products to have such or similar problems.
I'm trying out a new SIM card from a different provider, as recommended by few members in other threads. I hope it'd work out.
Fingers crossed....Will update soon.....
Narasimha
Same problem here, as soon as I activate 3G or enable data transfers, my Defy+ reboots. To use it I must be quick enough to disable data et go back to 2G.
This problems happens with or without Motoblur account and I tried to exchange the sim card of a working Xperia, the Defy+ reboots, the Xperia went on good surf!
I also tried to update the android system (from 2.3.4 to 2.3.6), it does not solve anything.
Another test with a SIM card from another service provider (Orange) show me the Defy surfing on the Web with the 3G or H symbol (in blue like for the wifi) and without rebooting. It looks like a frequency band swithching problem because my service provider (Free) does not use the same frequencies for UMTS or 2.5G.
As this problem seems to be ignored by Motorola, I will ask for my money back and buy something else. But on the paper, the Defy+ is a great smartphone.
bonsoir lepat, on a le meme portable et le meme probleme, j'ai toujours pas trouvé de solution au reboot du telephone defy+, j'ai une puce free et je suis obligé de rester en 2G uniquement et encore sa reboot malgré çà. si j'ai bien compris ton post en anglais, le fait de mettre une autre sim comme orange par exemple le telephone fonctionne correctement ?

Hi everyone,
First I'd like to thank those fearless tinkerers that produced (and explained the how-to) the Froyo upgrades for the Huawei s7-104.
I actually bought the device only AFTER downloading the Indonesian upgrade (that was-and still is-the extension of my faith in you).
The process worked like a charm and I successfully checked and confirmed that the new version matched the claimed upgrade.
I later managed to root the device and now even enjoy a longer battery life thanks to CPU Master set on "on demand".
The only problems I encountered were:
- Sometimes the screen orientation gets stuck in horizontal or vertical and the device needs to be rebooted to unlock the orientation. This is minor and doesn't bother me that much.
-I have lost 3G connectivity and neither the carrier nor a mobile lab has managed to get a shred of data into the device with anything but WiFi.
The Network pane says that it's connected and should receive data.
The APN settings should now be reviewed and corrected since I brought the device to the carrier's office and, after their failure to fix the problem, to the lab (they told me they did anyway).
The SIM was then taken out and connected into another device. It received data merrily, proving satisfactorily (at least to the C.Y.A. carrier) that they could not help me further.
Everything else works beautifully, phone, WiFi, GPS, everything...
Any idea? I live in Mexico and the carrier is Movistar.
Thank you in advance.
Thimage
screen orientation quick fix
can't comment on the 3G problem din really face it
you can try flashing to another rom
Zmey Mod from Belarus! would be a good choice
for screen orientation just install shake n rotate from the market
it's just a quick fix which can settle the problem
Thanks for the shake'n rotate tip! I'll try it!
Never heard of the zmey mod from Belarus. Is it in english or in local lenguage? I'll try to find it anyway.
Anybody out there who's actually had the same network connectivity problem that I've had? Can't be the only one right?
Thanks again,
Thimage
Connectivity recovered
I finally recovered connectivity by looking for the right APN on the web and I found it here:
decibel-elektrobeat.blogspot.com/2011/04/3g-de-movistar-configurado-en-xperia.html
The reason why it didn't work before is because for some reason it is not enough to correct the APN after flashing the Rom. You have to delete it and create a new one.
It works fine now.
Thanks. T
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!

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

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?

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.

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...
Hi all, this is my first post or thread, i came here cause i heard from ppl this is best site for asking questions about cell phones, i started reading allot this forum and wow did i enter the other world i really like and wanna participate in.
Srry for little intro and lets get back to topic. So i got my first "normal" android and got trouble with it. I am using Samsung galaxy s5 g900F (european) factory unlocked and T-mobile as carrier with 4.4.2 kitkat. I have a big problem with a data connection that keeps going off every 30sec to 5 min if i use option to search and auttoconnect on LTE/WCDMA/GSM option. I read forum but no1 is mentioning this model as problematic 1 so now i post thread about.
Does any1 know what could be problem and how to solve it. Sometimes my data connection comes back and sometimes it doesnt and i have to switch type of network to get back again online. All other options that don't include LTE auttoconnect work just fine, i tried to get another SIM from carrier but same problem, i tried to get another Phone since i work in hardware firm and still same problem on another device, both were same models.
I still didn't put any ROMs but i really consider doing it maybe l8r on, it is stock version.
Pls be genttle since this is first time i post, maybe i did it on wrong place but i did read rules and everything and i think i did it on right place.
Ty in advance.
I did have a slightly similar problem years ago - when in roaming my phone could not connect to anything. What helped was a change of simcard for a new model - after that all was good.
Since you did try your SIM on a different phone (same 900F?) I would advise you to try: first on a completely different brand and phone model - if you can.
If this does not solve your problem do shake your service provider a bit - they could have supplied you with two faulty SIM cards in a row - that can happen. Otherwise - maybe there is a stupid limitation in your service plan which is causing this. There is no - to my knowledge - ready answer to the problem you have described.
Best of luck and if you do solve it come back and post - it will be very useful to lots of people for sure
Cheers!
Too many variables. You haven't observed enough of a pattern yet or tried enough things to narrow it down a bit. It could just as easily be carrier side issues as a bug in the firmware not negotiating a new connection if the LTE signal is lost.
A number of people were having data disconnect issues and that was addressed in the 4.4.3 /4.4.4 update. So that is one option to consider. And you could open a support ticket with your carrier. That is hit and miss as to results, but sometimes tickets actually resolve issues.
There are also a number of apps that may mitigate or possibly even solve your issue. Have a look at 4G LTE Switch and LTE Discovery.

Will try it today. Thanks for the help. Really appreciate it.

I did have a slightly similar problem years ago - when in roaming my phone could not connect to anything. What helped was a change of simcard for a new model - after that all was good.
Since you did try your SIM on a different phone (same 900F?) I would advise you to try: first on a completely different brand and phone model - if you can.

Hi everyone, my H870 has seemingly given up on me out of the blue since about two days ago and refuses to connect to mobile networks, or even to search for them for that matter (trying to manually search for networks give back an error). I'm afraid the issue might be hardware-related which would be a shame as the phone is otherwise fine. I've tried changing ROMs (going from and old AEX AOSP to LineageOS, with full wipe) as well as kernels (Melina reborn for AOSP), to no avail.
Switching sim cards also didn't change anything, the sim is detected and it asks for PIN but then no network, which leads me to think it's a radio chip issue. Activating radio in the *#*#4636#*#* menu doesn't prompt the usual restart, and auto-untoggles if i go into another app then come back to it... IMEI is fine and not corrupted.
I'm really close to giving up on this phone and buying another one, but I thought maybe you guys would have another idea of something to try that could work before I do that. Couldn't find any similar threads on that matter but please point me in the right direction if this issue has popped up before !
Thank you in advance for your help.
EDIT : Flashed original firmware (H87030a_00_OPEN_EU_OP_0829.kdz), to no avail... I believe this is the end of the road for this phone and judging by the lack of answers you guys do as well haha
H873, should not have reset. Now i dont know too
