MB526 (random) reboots, fix? - Defy Q&A, Help & Troubleshooting

Hi, i have problems with random reboots its really annoying.
Some roboots arent random - when i recieve/send sms phone reboots almost everytime or when someone calls me its the same - reboot.
Any fix for this?
Thx
I have Defy+ (MB526), 2.3.6 android, 2.6.32.9-gbdd614e kernel, stock ROM

try wipe or flash other sbf that you can flash

Don't flash anything, if it persists after a wipe, send it back

Someone on this forum reported rebooting issues caused by a slightly shorter than spec battery (actually a few people as I recall). When the phone was moved it often rebooted and the fix was to add a single piece of electrical tape to the end opposite contacts. May be worth a try.

Switch to 2g and mobile data off then see if it reboots.
Might be this-

Ok, thanks for the answers, flashing doesnt work Ive tried it many times..
Ive just tried 2G and electrical tape, hope it will work

A few causes might possibly be the answer.
1) firstly confirmed the rom by playing the overclock settings. Some rom having too low on voltage or frequency setting. Or the rom itself is not stable. Flashing another rom is only way to confimed this.
2) Battery might have factory defect, use battery monitor widget to monitor the voltages/current of the battery consumption. change battery(borrow from friend) to see if the reboot still happen.
3) Check battery connection on the phone. Make sure no loose around it.
4) If all the above still causes the random reboots. you can return it back to the shop to repair the handset.

seems switching to 2G helped, no reboot since switch, thanks

This is the same problem I had with my Defy+
It used to reboot randomly for no reason even when siting on a desk doing nothing
all of a sudden i would hear a notification to say the sd card was loaded informing me it was rebooted.
When it does decide to reboot it can do up to 4 or 5 reboots continuously
I sent it back and got a new one.
The new one does the same thing but very rarely
maybe once every month or 2 months
I have posted about this on the Motorola Forums and There are other people with the exact same problem as us.
One of them mentioned they had to send their phone bak to Motorola and they replaced the main board and will get back to say how it went.
But since then no answer and Motorola changed their forums

Can you confirm if it's 2G or tape?

I purchased Defy+ 20 days ago with exactly same configuration as the one described in the beginning of this thread. Phone reboots at random when I am in the middle of conversation, or while accessing data through mobile network or while present in areas with extremely low single. I tried using a new SIM, checked loose ends (if any) of the battery i.e. stuck a 1 layer of tape on one end, also switched to 2G. The phone continues to reboot especially when I access internet on mobile network, and also booted once while I am in a call.
Unfortunately the customer service in India (any company) would be pathetic so I'm not hopeful in having Motorola fix the problem if I take the piece to their support centers...
Narasimha

Narashima,
I have heard of Defy going crazy when trying to access data in an area where the data signal is weak and goes in and out. Can you confirm you are getting reboots if you turn data OFF? Not sure how your phone is configured, but I mean even cut off 2G.

i tried so far flashing it from SEUS, removing apps, playing around with settings
its a problem so big for me im concidering changing phones, and returning the x10 to a shop or sending it for warranty arnt options for me

no, usually happens after it just booted while doing a random action
Probably time to back up your apps and wipe things out. Also, defrag your SD card because a few times mine became amazingly fragmented.
You could back track and try figuring out what app or what change had caused this but for the same amount of effort you can start fresh. I routinely wipe things out. I do it partially because if you only do a few reformats every now and again it becomes a daunting, intimidating task where you fear losing important info, etc.. just my two cents.
Mine is doing it too, while I have almost no extra applications installed and I don't use timescape and very rarely mediascape.
Just laying on my desk when suddenly the display lights up and the phone says simcard locked (asking for my pincode).
Happens approx. once every 1-2 days, and sometimes a short time after I reboot.
I never noticed it in the almost 6 months I have this phone, until I plugged in a new simcard with the pincode request active

Reseating the SIM and SD card can definitely help too. But I've personally used the same SIM cards for years without challenges on the network or with my phones. Sometimes you get a dud or some dust in there.
I like using Hot Reboot to reboot my phone from time to time as well. I don't do it too often because I like to see how long my battery lasts, but it helps out a ton. Much better than killing tasks. I only do that before putting my phone to sleep for a long time, just in case some stray apps don't close or trick WiFi into staying on, etc.
My phone seems to be rebooting much more when I plug in to charge (while on the phone or having the earphones plugged in) . . . Its really annoying. Last night just trying to talk to my girlfriend it rebooted about.. 7 times? Less than 30 minutes. That is very frustrating. . I'll go home later and try to defrag the card and maybe the sim and such. I'll see what happens.. if it keeps up I might just have to go back to the storm1 until 2.1 comes out. Hopefully that'll fix this rebooting problem..

same here, its a perfect phone i and i dnt mind anything in it but the reboot problem, cuz i already have a couple of deals lined up to sell it and if the prob isnt fixed any time soon im gonna take the plunge and sell it
it is a hardware failure. If you smell the back (behind the cover) u smell something burning. it will hapen more often and than you have to take it to a repair center where they can fix it under warrenty. They are repairing mine right now.....
I have same issue in HK & got replace mainboard but still got error restart.
Finally they change a new X10i to me beside they need me keep my old back cover!
My friend has got the same issue and the phone was sent back with the same problem again. In return we sent it back again to sony and we received a new phone
I wonder if the restarting could be related to wifi,
I didn't enable the wifi for about 2 weeks now and it didn't reboot once.
Just leaving 3g network on for the moment.
get your x10 replaced with its motherboard. i had to threaten legal action just to get the restart loop fixed.
its a very common problem with a faulty batch or with the phone itself. you can check all the complaints here

m8 i had exactly the same problem first the restart was just randomly and then the START became random i mean when i boot my phone it restarted itself over and over again so i turn it off and leave it to rest then when i switch it on again i was able to use it about 30 min and then the restarting session comes back again and i wasnt even able to log in to Android OS . The device just reached Sonny Ericsson logo and restart .SO i gave it back to the shop i bought it from and after few days they gave me new one coz it was some hardware issue they couldnt fix that was the only way to repair it for me.
P.s. 1st i bought black xperia but they gave me white cant be more happy coz i wanted white when i first went to the shop but they ware all sold ..
I think it happens when the phone gets too hot. check the back of your phone and feel it it is overly warm, I know my phone has rebooted sometimes when I have been doing cpu intensive tasks and multitasking or using the gps for a while. This happened with my g1 as well.
Are you using a Task Killer? If so, do NOT kill the Backup and Restore application on the phone and see if that resolves your problem.
I know it sounds strange, but I was having a similar issue where my phone would randonly restarted. It only started to happen after I did a firmware upgrade that installed the Backup and Restore feature (I'm on Rogers). Once I stopped killing the app, my problems stopped.
For mine it was GPS. Disabling GPS stops rebooting the phone.
bad chipset... return to se.
Before I tried all the other MODs, especially Froyo ROMs, everything works fine.
After trying and flashing and downloading and ... my GPS will now work for nearly 30 mins or equal to kilometers driven and then reboots or GPS signal lost
It needs to cool down or the timeframe will be shorter just after the reboot. To turn GPS on/off will not work.
I tried everything in any possible combination:with and without backcover; car charger; Navigon, MAPs; reflashed back to 2.1 Stock; formatting SDCard; changed SDCard - problem remains
I wouldn't say that it's the cover will be hot..yes warm, but that's all.
My problem is, that there is a little crack on the touchscreen on the upper left side, so I guess SE will not replace my generic full-paid handset.
I still have this problem lately, and it is right out of warranty, so i am stuck with this phone.
I check with robbers (rogers) if i can get another phone cheaper... heck they are selling me old smart phones more expensive then the market.
I think i am through with Sony ericsson, phone is nice but their choice of manufacturers are horrible.
Seriously, Sony deserve to be hacked and deserve to lose billions.

Randomly presenting SIM pin code screen when waking phone from standby

I've had a repeated problem (around 4 times so far) where my phone mobile radio must have died/reset while the phone was on standby with the screen off. When I wake the phone I am presented with the SIM pin code request screen. Usually entering the correct code reserects the phone. However last occurance it refused to accept the correct code so required a reboot to get it to work again.
Anyone else seen this?
I'm on O2 in the UK fyi.
Sent from my Nexus S using XDA App
ok I'll guess the answer myself...
I guess this is related to the random reboots people have been experiencing primarily on calls. I note some people say the phone can reboot while on standby, since I 'had' SIM pin code enabled this was as far as the reboot while on standby was getting. I've removed the pin code request which will mean I guess the phone just completes the reboot without requiring my input.
I'm hoping this is fixed with any update to the reboot during active calls issue that google confirm they have repeated themselves.
I've just had this happen on my Nexus S. What service provider are you with? I'm with Tesco (O2).
I'm O2, 30day rolling contract. Basically I've disabled the SIM Lock now so hopefully until the standby or call (not experienced this one yet) reboots occur the phone will just restart without my intervention required now.
Same here. After connecting the phone to the charger yesterday evening, this morning the SIM Enter PIN screen showed up (like the phone did a reboot overnight).
After checking the system services, I noticed the phone hasn't rebooted, because the services where running for more than 12 hours.
So the SIM Enter PIN screen showed up without reboot. I think a no-signal situation has preceded before this screen showed up (and maybe the GSM module has got a total reset).
This is on Telfort/KPN, The Netherlands.
Interesting ArnoutVos.. these were my original thoughts too since every time I've had the phone next to me and not seen it reboot just present me with the Enter SIM Pin screen. I just naturally assumed I was getting the at standby reboot some people had seen.
I've got the same problem on t-mobile. Probably about 6 times in 2 weeks so far. I've also had it where the signal bars at the top just show grey with a little cross by them and the only thing i can do to sort it is restart the phone.
It also drains the battery like mad whilst in this state.
I also had this 2 times (only had the phone 5 days)
That is, i turn on the screen and i have no signal, I dont think my phone has been restarted, as i dont see the sim pin screen, it has just lost the signal/radio died. And nothing seem to restore the signal, i've tried switching from 2g and back, only thing i found to get the signal back is a restart..
i have had the same problem with the signal dropping out on me all morning. sometimes i can make calls sometimes i cant and sometimes rebooting helps sometimes not. today i had the sim card replaced just to make sure and i thought it helped but it just did it to me again. its really frustrating...
I had the same problem about 10 times during the last week. It seems to correspond with the creation of Radio_dump files in the /sdcard/ dir.
Nexus S, Android 2.3.3 Root
I get the same issue on A1 in Austria, not sure what's causing it, but it is annoying.
Let me give my 2 cents:
Getting this same thing happening all through the various combinations of roms and radio firmware, device is Nexus S 9020T, network is T-Mobile in Croatia.
CM 7 with I9020XXJK8 radio
CM 7.0.2 with I9020XXJK8 radio
Blandroid 2.3.4 with I9020XXJK8 radio
Blandroid 2.3.4 with I9020XXKB1 radio
Sometimes there is no pin input screen, so if I don't notice the little icon in the notification bar I'm completely unavailable to calls and sms's. During the time if the Wifi is on it will continue functioning normally, and radio dumps get created.
Will give newer radio firmwares a try before I start crying in my pillow.
Edit: don't know if it happened with stock android 2.3.3 which came on the device, didn't have it on stock for more than 15 minutes.
Alas and damnations, again mobile network radio fail, this time with
radio I9020XXKB3 and blandroid 2.3.4, so issue still present.
Only fix is reboot, airplane toggle does nothing. Does anyone else in europe experience this with a USA T-mobile version nexus?
Giving I9020XXKD1 a try, still with blandroid now 2.3.4p1. Keeping my fingers crossed!
Well well...seems to be a common pattern, as its happened to me a few times also in the last week. First time ive experienced it also...just over a week.ago. cant remember which rom i was using as i.change quite often. May have been a new 2.3.4 mod or just 2.3.3 im not sure. Not a good thing obviously but not a big issue so far. Hasnt happened again since about 3 or 4 days ago now.

Such problems can occur when the SIM is disconnected from power or from reset line or has technical difficulties making it reboot.
Power or reset line can be disconnected if you have your connectors inside your Nexus bent. This can be tested by shaking your phone heavily in all directions. Be careful not to drop it. If the Enter SIM or the Enter PIN dialog appears, It's most likely a mechanical defect of your phone.
If the SIM is broken it may be reset itself. You can't really test this. Maybe something appears in the system or radio log. Another way would be to place your SIM in a known-to-work phone. If similar problems occur it's a broken SIM. You should call your provider to send you a new one.

Those are some good advices, thank you.
I would rule out bent pins as the cause and also no amount of shaking produces the problem, and the problem happened always when the phone was on the desk (and connected to wifi for what its worth).
However, a broken sim - maybe. I haven't had any problems with it so far in any of the 2 previous phones and I'm careful handling it, but the radio log suggestion is excellent.
I will definitely go through it next time it happens ( its "adb logcat -b radio" so others don't have to search for it)
Does anyone got a solution on this?
I found today about 10 - 15 dump-files located in my SD-Card.
Its probably caused by an App which we all use... but i couldnt figure out which one...
is there a dump-debbuging programm which i can use or something else?
It's kind of interesting
Using a Nexus S in Austria (T-Mobile)
I've "solved" this by disabling the PIN altogether and setting up a script to run when the network is changed to delete any radio dumps:
http://forum.xda-developers.com/showpost.php?p=17114685&postcount=26
It doesn't seem to matter which ROM, radio or kernel I use....I wonder if this is a hardware defect?
sorry to resurrect an old thread, but this is to report that on my sns on pete alfonso's 4.0.3 rom and matrix 14.5 CFS and KF1 + KD1, I still get this problem of the radio dying.
has anyone found a solution?
to be more precise, the mobile network connection (calls and data) randomly dies and the only way to get it back is to restart phone. airplane mode doesn't help.

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....

No network after installing CM7.1

HI ALL, Im pretty new here. after so many tries finally i was able to install cm7.1 on my defy. but im facing some issues. before the installation i forgot to take a back up of the existing ROM so if i have to go back to the previous ROM how to do that? and also there is no network coverage after the installation. please please anybody help!!!!!!
Have a vibrant myself but I'm helping a buddy get cm7 on his defy and after flashing didn't have a network signal. I looked at the cm7 install guide and it referenced a defy base band switcher app for better coverage. Had him try that and he got his data connection back. Might want to look into it or read the guide.

If your previous ROM was stock that came with your phone, flash the corresponding SBF file from the sticky on the Dev section to go back to stock. If it was some other custom ROM, wipe data/factory reset in CWM and flash the old ROM. Make backup of your apps using Titanium Backup if you want.
For CM7 network issues, choose the correct baseband from Defy Baseband Switcher. For India, pick anything that is 900/2100MHz...
Also, make sure you have read as many guides and First Posts on important threads as you can. Here is a collection of good threads you can read for these questions, and more that you might get later:

Hello! Noob here as well.
I installed CM7.1 stable on my Defy (running 2.2.2 foryo) 2 days ago.
All went well, except that network connection is lost after a couple of minutes after boot. Sometimes it takes an hour or two but I still end up with no connection.
I've googled everything about it in the last days. I played with the Baseband Switcher and although most options in the BB Switcher work right after a reboot, it still looses the signal after a couple of minutes.
One thing I noticed, when the signal is lost, trying to set the "Airplane mode" will fail. If trying to set Airplane ON - the notification icon will not replace the signal icon and will also be unable to set Airplane OFF (since it didn't finish turning ON).
I also noticed that if I force stop the "Dialer" system app, then the Airplane notification ico shows up, but still there's no way to turn it OFF (it's disabled in the menu). After a reboot Airplane can be set OFF and everything works for another small period of time (..until baseband crashes again?).
Hope it makes some sense. I'm quite sure this is not an operator issue or hardware related, since my Defy worked just fine before CM7.1
Also, I am located in Romania, operator is Orange.

I have the same issue, except that it is much rarer (ranging from every other day, to even a month between such incidents). It can also be triggered sometimes when I turn off Wi-Fi and the device tries to regain mobile data connection (not sure if it matters, but I set the network mode to 2G on my phone). The battery drain is increased if this occurs without the user noticing - the phone seems to search in vain for the signal.

I get this problem too. Happens every so often when I'm at work. I've always put it down to a bad signal where I work but as I always turn the wifi of before leaving home it could be down to that. If anyone has any solutions it would be great
Ok, a little update on this:
At the office now, further playing with the Baseband Switcher, I ended up selecting "Italia RT 2.51.1" which has the same 900/2100 freq that my operator requires and it seems to work. Even getting 3G.
If "2.51.1" is some sort of protocol version, then all the other options I've tried were either 4.x or 3.x or even 2.21.x ..and none of them worked for more then 30 minutes.
Also, not sure if signal strength has something to do with this because I did a test, going to the basement of my office in order to loose signal, then back up and it worked - got the signal back, without reboot or anything.
Also, I would really appreciate if someone could explain in a few words what those version numbers mean (ex: "Italia RT 2.51.1"), as I know nothing about gsm bands and protocols.
UPDATE: Back home, lost signal again, after a whole day without any problems. Funny.
UPDATE 2:
So after much google searching and trying literally every option in the Baseband Switcher, I switched my SIM card with a friend's SIM and guess what.. IT WORKED! Even more, when I inserted my original SIM into the other phone after a few minutes it lost signal, too! It was a faulty SIM, that has just started to "die".
Conclusion:
- Keep playing with that Baseband Switcher until you get something that works for you.
-Make sure your SIM is working properly in other phones, otherwise ask your operator to replace it.
Thanks and hope this helps.
ZeDevil did you try using other Basebands to see if you get better battery life ?

Not really. As long as you have a working Baseband selected (with correct frequencies) I don't think it matters.
But overall CM7.1 has better battery efficiency then stock ROMs, or at least that's what I felt.
update:
Well, I had a play with the baseband switcher, realising i was on 'international'. I switched to uk t-mobile and from there it seemed to work much better. A slight blip at work today (think it's a bit of a signal black-spot though) but restarted and it seems fine again. I've also just realised it's gone 37hrs since its last charge too
Strangely my other problem, the backlighting on the soft-keys not working, fixed itself at the same time. dunno if these two things are linked or not?
i use the CEE one.

i got a GS4 from a friend of mine that he had some problems with. i took the device and assumed that it just needed to be reflashed. boy was i wrong, lol
it has some weird issues with ANY rom i flash (and ive tried about 5 dif ones)
issues are as follows:
1) when i try to make a call or try to use any GSM shortcodes (*120# to check balance in my country, Jamaica) the phone freezes. it still tries to make the call, as i see the little phone icon in the top left corner but nothing at all
2) sound doesnt work at all
3) wifi doesnt work either
the strange thing is, when i flash a rom, it boots as normal, and i can go into the menu with no issues, but once i try to do any of the above, it freezes and then normalizes about 3 - 5 mins after.
im relatively experienced with rooting and flashing as i had a Note as well as a mytouch 4g.
it has the latest safestrap installed. to be honest, im unsure of what my friend tried to flash to it, but i figure that it might be a radio issue for the wifi and regular calling.
as for the other stuff, im stumped.
any help is greatly appreciated, thank you
If it's having problems with the sound and the wifi isn't working, my guess could be water damage. If the problem is with ANY rom, there may be a problem with the device itself. Best way to see for sure it's water damage is checking the battery water indicator, if you wanna go deeper, remove the backing of the phone and check the water indicators.
dont think its water damage tho. battery indicator seems clean. and i stated before the phone works part way but freezes when i try to perform certain actions
EDIT::: even when i try to reboot it freezes for abt 2 mins then reboots. its like the phone is lagging internally for some reason
no information available?
