[Q] [REQ]Pls Help - ACTIVE ST17 Random Reboots - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

I am writing in desperation.
My Xperia Active is about 3 months old.
It is the ST17a version but that has never made much difference to anything else.
It has been unlocked via testpoint method so warranty is not valid (plus they don't sell this phone in my country anyway).
Phone randomly reboots when it is not plugged in to power, especially when trying to bring the phone out of lockscreen standby, after using any GPS function or just unlocking the phone
The fact that this WILL NOT happen when plugged in to power is telling me perhaps it is a power management issue.
Things I have tried so far: COMPLETE REFLASH formatting all available mounts from recovery mode + format SD card and start fresh.
Combinations:
1.Spartan Rom 1.9.5 + non-oc kernel
2. Spartan Rom + Rage Kernel
3. Different baseband versions including original (56??), .66 and .62 (currently have .62 installed)
4. EX MIUI + ST17 satsuma kernel
Reboots still happen with all of the above configs
The problem started suddenly whilst using GPS SportyPal pro + Bluetooth music I have previously not had any problems in this area but now they will not stop.
I did not experience any reboots with CM9 but I did not stay in that rom very long as there was way too much stuff not working on my handset - it probably would have happened eventually. Sometimes I can get over half a day of usage without a reboot but then will get like 5 in a row.
I absolutely LOVE this phone but I bought it primarily for sports tracking and it keeps crashing and losing my workouts so I'm getting pretty pissed off.
If anybody can tell me what to look at to try and track this down I would really appreciate it. Checking logcats are no good because it will never reboot whilst plugged in to USB. Are there any other logs I should check???

OK - if not any help to identify the cause - can anyone comment on repair cost @ sony service center out of warranty?

Try fully stock 4.0.2.A.0.62 firmware, some other phones had issues with restarting all the time also, this firmware is known to fix this.

SOLVED - have carried out 5 days of testing.
I can confirm the latest version of MIUIex has addressed my reboot woes.
Have been running reboot logger 1.9 on the phone since then and have not had a single unexpected reboot. I am a happy camper.
Not sure if perhaps there is/ was a common driver or something that was causing these problems between a few of the up to date roms - I am just happy the issue seems to have passed for now.

And it's back. I switched back to Telstra, that means back to 850mhz band, reboots are back with vengeance. Might need to try and find a st17a specific Rom and radio.

Wow, thanks!
Seems to have done the trick but now is back to vanilla flavour - seems the rooting process has gotten ridiculous lately, I wonder if it would be easier to pull this ftf to pieces and insert the radio detials etc into another rom file.
For now I guess I will use stock phone unrooted, at least it won't reboot.
THanks for your help!

i have also had that problem. I flashed the sti7a ics version and it is gone, after that you can use any rom without any prob.

I had the same problem, it used to happen when signal was scarce or absent, i solved by getting a new sim card

[Q] Don't install new firmware - it bricks the phone!

Hello,
I downloaded the official rom from the official HTC website.
It is the WWE East Europe version - suited for my device because the SN is confirmed.
The download finished OK from the Europe 2 server.
I flashed by placing the extracted leoimg.nbh on the root of the SD Card.
I confirmed that the flash was successful - it shows the correct version number of Manilla, radio, etc. Additionally, the ROM is still only 448 MB.
However, the phone freezes all the time and/or restarts itself complely randomly - I have observed this 22 times in the past hour. Is anyone experiencing something similar?
I have redone the flash again, but the same issue occurs.
This is happening with no programs installed, no HSPL, etc. Everything is completely clean.
What can I do to stop this?
may i know why you flashed the latest stock rom using your sd card. would it not be easier to flash through your pc using a usb cable?
you might want to check the meaning of "bricking the phone"...........
then remove it from the title of the thread........
As Rurph mentioned, flash it via your pc, still following the instructions from theHTC site
I now tried flashing through PC, same freezing occurs.
To reiterate:
I have an original HTC HD2 bought from the official HTC shop in Czech republic.
I downloaded the latest official ROM for HTC HD2 from the official htc.com/cz website using my original serial number.
The download finished successfully every time (I tried it 5 times from all the different servers), and the SHA-1 hash of the files was identical every time.
I now flashed it using the normal PC method - everything appeared successful.
I also tried extracting the nbh file from the downloaded file - both by running the .exe file, and by extracting it using winrar - both methods gave me the same nbh file with the same SHA-1 hash. Then I moved the leoimg.nbh to the root of SD card and flashed using the SD-Card method. Everything appeared successful.
Both of the above methods give me a system that freezes completely at random. For example when starting the phone, it can just freeze (left it for 8 hours over night, it remained frozed), when moving from 1 tab to another (freezes in the middle of the animation), when opening the start menu, when going into settings, when making phone call, when opening SMS, and most importantly when NOT DOING ANYTHING AT ALL.
What can I do?
Try to flash an older Version.
I don't know if its possible, but maybe that solves your problem.
Did you have SPL 3.03? If no... Install HSPL and use a custom ROM like the one from NRGZ28 (EnergyROM)
If you an't flash the older version via RUU (Rom Update Utility) try to flash it from SD card. You can also perform a "task 29" with MTTY (before you flash)
But be careful, you can brick your phone...
I have always only used official ROMs from HTC, so I never needed HSPL so I never installed it. I also always prefer the official ROMs so I would rather not use a cooked one.
I think flashing an older version would solve the problem, however I would rather like to find out what the cause is...
So far, I managed to get my phone to a useable state by running Android from the SD card - it works flawlessly for all my purposes. The only problem was to start Android through Windows before windows manages to freeze...
Given that android does not freeze, I believe that the freezing problem must be a windows mobile issue.
Any suggestions for tracking down this freezing problem? Could it be a hardware issue?
hard reset. and if no better flash the rom again followed by hard reset.always hard reset straight away as soon as you see a glitch in a freshly flashed rom. don't ask me why, cos i don't know, but it does seem to help when a flash doesn't "take".
oh and you didn't leave the old application data folder on your sd card did you? or try to restore registry settings?

I always hard reset before and after a flash. No change - freezing still occurs.
Even when I did multiple hard resets, the freezing persisted.
The SD card is freshly formatted, checked for no filesystem errors.
I did not restore any settings or anything else - the problem occurs on a completely fresh clean flash.
Additionally, the problem occurs even with no SIM card or SD card inserted into the phone.
Overheating?
I concur with rr5678, seems more like overheating than ROM problems, esp. that I've had the same ROM for a week with no problems whatsoever
hence kind request to OP: check overheating threads and please change the thread subject to a more accurate one so it does not spread misinformation and panic
as for the overheating - 1st thing to do is installing BattClock and monitoring correlation between freezes and battery temperature
rr5678 said:
Overheating?

The phone is definitely not overheating. It is very cold to touch and it runs Android without a problem.
OK I did some more testing - going back to any previous ROM fixes the freezing. Then installing the newest ROM reintroduces the freezing.
Given that it is definitely not a hardware issue (works on previous ROM, works on Android, no overheating), it looks like a Windows mobile issue.
I am surprised that nobody else is experiencing this. How come I am the only one? What is so special about my phone?
And the new firmware can "brick" the phone - a less skilled user would not be able to do anything with a frozen phone...
Anyone know why I get no ringtones or alarm sounds when using 1.8?
Deliberate?
Edit: Weird, seems first time a check a ringtone or alarm sound list it's empy. I leave then go back, it's populated again. So self-fixing issue.
Edit 2: Yeah.. tabs got mixed up, completely wrong thread, sorry!
Anyone help?
HTC Support is as always useless - their advice was to take out the battery and put it back in...

Thanks for the advice - but given that the phone freezes even with no SIM card inserted, I do not think that it is the case...
I have however tested inserting a different SIM card anyway, and the freezing occured again...
I too faced constant freezing problems with the official ROM but then I used HSPL and flashed a different radio (2.12 in my case) and ever since never faced any freezing problems..worth a try I guess...
epic fail
not being picky, but "bricking" is, as far I know, by definition an irreversible problem? Hanging and freezing and re-booting are not bricking.
That said, sorry to hear about your troubles.
Sounds like going back to your old ROM is the only solution right now.

Well, to me it seems your phone just doesn't like custom ROMs.

[Q] Phone completely freezes after ICS update. HELP!!!

Hi guys,
I have a huge problem. I had a stock GB firmware customized by Optus (carrier in Australia) on my S2 I then decided to change to the new ICS 4.0.4. I downloaded the stock unbranded firmware from SamMobile (Australia 2012 September 4.0.4 I9100XWLPW, I9100XSALP6, XSA) I updated using Odin. Before I did the update I reset the phone, did the update, it all went smoothly. After the update I reset the phone again and then proceeded to reinstall all my apps and restore my contacts, sms, etc.
The phone works and all functions on it work, however now very randomly the phone would totally freeze. The phone would be in standby, the screen would come on and it would be frozen. The screen stay on all the time and it does not respond at all. It will stay frozen until I restart the phone by pressing Home+power buttons to restart it.
After restart it all works fine for a few hours, sometimes a day and would just lock up again. The phone is not rooted and as I said i just changed the firmware from the Optus branded GB 2.3.6 to unbranded stock ICS 4.0.4 by using Odin.
Is there a way to find out what is causing the phone to lock up like that? Any suggestions would be helpful.
and then proceeded to reinstall all my apps and restore my contacts, sms, etc.

I made sure that I didn't restore any data apps. The only apps that got restored are the ones that get automatically restored by Play store.
I have disabled the live wallpaper that I had and it seems to have stopped the freezing for the moment. I will report on what I find out.
In the mean time if anyone else has a similar issue or has a definite solution please let me know.
Thanks
i know this is a resurrection, but don't see it has been resolved.
also found same/similar problem on another topic, but no resolution either.
couldn't find any resolution anywhere on the net, but possibly i'm just missing it (searching for wrong parameters?)
anyway, a friend of mine bought second-hand (third or even fourth hand to be precise) i9100 with 2.3.6 (stock KI3) on it. the guy who sold it to him said something like: "it works best on 2.3, on 4.x it's buggy".
it was working fine, but friend wanted newer OS, so we tried update. it didn't work, and i found out CSC was broken/missing. somehow i managed to repair it, and update was finally working, but was unable to find any for our location.
so next step was to find stock rom that would work on the device, and then i tried four different 4.1.2 stock roms from this topic.
after flashing it through odin, every one was acting fine, until couple of minutes after it started freezing or rebooting randomly.
then i tried flashing CWM, and flashing from sd card, but it was all the same.
wiping data, cache and dalvik cache, prior to flashing. wiping data after flashing...
nothing seemed to work.
GB works rock solid, ICS works better than JB, but stills it freezes or restarts randomly.
tried CM10, but all the same, except it works a bit faster then official JB. but who cares about speed if it freezes/restarts constantly?
back to who knows which build... freeze... samsung galaxy s2 - i9100... with yellow triangle... booting stopped.
so i decided to dig deeper, trying to find hungarian stock build (country we were told the phone came from) not being sure that KI3 is what the phone came actually with. i found 4.0.3, put it on SD card, wiped data, cache, flashed CWM, wiped data, cache, dalvik cache, flashed 4.0.3 from sd, wiped data, booted, entered location for updates - hungary. update found, hooray... downloading... installing... rebooting... working?
nope... it's worse than ever. trying to log onto google account. typing in email add.... freeze... switching phone on - freeze... thinking about... freeze.
i couldn't sit still. yellow triangle, all those reboots/freezes... at least i wanted that triangle gone, and without a JIG, there was only solution for me was to try triangle away. it wasn't available for download in my country from play store, so luckily xda was there.
somehow i managed to download it from the device, install it, click remove the triangle... it did it's magic, rebooted... and miracle happened!
no more freezes.
so i started torturing poor phone, benchmarking, playing games, listening to music.... it seemed stable for about an hour.
so i said to myself:
- it's possible that previous owners tried to upgrade it to newer firmware, and somehow screwed up the bootloader, which was fixed by this app? maybe that was all there was from the beginning? why not try putting 4.1.2?
and i did... took 4.1.2 spanish build from already mentioned page above, flashed it... and voila. working JB... torturing the phone... playing with it... hour passes, another hour...
friend wakes up... takes his phone in awe, starts playing with it.. we talk a bit... and then that look it just froze again!
from that moment on, the phone again starts restarting or freezing randomly...
and, yes, i still have no clue what could be the cause. it doesn't matter if wifi is on or off, if you're talking on the phone or not, bluetooth and gps are always off. only thing that he noticed is that it usually happens while he's using the phone (meaning: operating the digitizer or buttons). if he starts music playback and not touching buttons or screen, it will probably play for hours.
one more thing, but i doubt it would be the case. the battery in the phone is not original one that was shipped with it, but a quality replacement.
it doesn't feel as if the phone is overheating... so i don't know what else i could do with it.
for now, it's back to 2.3.6.
we both lost a week, torturing ourselves with this problem.
i don't know is there anything i could add more?
all suggestions are welcome.
cheers
Maybe try kernel cleaning script and try philz or siyah kernels.
You shouldn't have to flash a custom kernel so your phone won't freeze, but yes, you could run a nuke script in order to wipe clean all custom ROM's leftovers.
Try flashin' jb via mobile odin, see if it keeps freezing up on you. If so, nuke it up.
Sent from the little guy
i'll try them out.
probably for the weekend, if not sooner. will report back here with info.
any other suggestions are also welcome.
thanks a lot.
cheers
ok, so here are some updates.
i finally got my hands back on my friends phone, and tried nuking remains of older flashes.
following that, i flashed stock spanish rom from above mentioned page, updated after installation to spanish update... and after a few minutes, sudden reboot...
so, went back to nuking, and flashed stock hungarian 4.0.3 i found elsewhere (mentioned in my earlier post. don't remember origin... if i find the link on another computer where i downloaded it on, i'll post the link). tried updating, says no updates found.
started torturing the device. it seemed solid, but battery reported it level was low, so hooked it up onto charger and all seemed well. but phone seemed a bit too hot.
after few minutes (this was all about half an hour to hour after flashing to 4.0.3), again freeze.
after rebooting the phone, battery was at 9%, as if processes were draining battery faster than charger recharged it.
so, i figured i gotta try original battery. so i switched his battery with genuine from my phone.
phone seems stable and less hot, for now.
still checking if it is going to freeze or reboot again.
it's about one hour since battery change. still on charger and using wifi and playing around with apps.
i'll check in with news later.
cheers
I have the same issue.but my battery is original.
What I noticed that the phone stuck when I receive an update notification.
Can I stop softwsre to ask for updates? ???
Sent from my GT-I9100G using xda app-developers app
^go to settings, about device, software update and detick auto update. that should stop it from trying to self-update.
ok, so here is an update to my friend's phone status.
currently on hungarian 4.0.3. about 3-4 freezes/reboots a day. sporadic connection breakups during calls. also, when we talk i can hear myself back. this brings me to conclusion it has to do with modem firmware. i found this topic, so i'll try putting that and see what will happen.
if that doesn't solve anything, my question is this: is there any way of knowing which firmware/rom was originally put on the device, since i don't know the real background of the device? i.e. some way of entering IMEI and finding out what should be on it?
cheers
EDIT: tried KH3 modem, no changes... i could still hear myself while talking to my friend on that device. also, it froze couple minutes later. going back to 2.3.5-2.3.6 for now.
so after couple of months, i finally got my hands back onto this phone...
gave my friend my phone, so i could play a bit with this faulty one.
i have played with it for a couple of days now, and here are things i've tried.
i received it from a friend with 2.3.5 on it which had triggered custom binary counter. he's been using it for couple months without any problems.
so i rooted it and installed triangle away again... reset counter, cleared and flashed hungarian stock (telenor) 4.1.2... random freezes again.
tried several stock roms, mostly hungarian ones (4.0.3, 4.1.2). even reformatted with .pit file... random freezes.
reformatted again with .pit and put XXLSJ, installed stability test and let it run...
cpu stability test 15.5 hours no problems, no freezes. then i realized it didn't have a sim card, so i rebooted phone and installed sim card. let it test cpu+gpu for 9 hours... no errors, no problems, no freezes.
so i thought, maybe it's all fine? but it wasn't! as soon as i took phone into my hands and started going through menus it froze!
so i tried SGII_repair, rooted and did "repair"... but nothing changed... still random freezes.
if i just let it do the stability test, it'll probably work forever.
things i've noticed:
- serial number is wrong format (14 hex digits instead of 11 alphanumeric)
- during stability test, cpu frequency dropped from 1200 to 800 mhz (maybe because it was getting warmer? 42-43C during cpu only+charging battery, and about 39-40 during cpu+gpu test)
i tried to find out which firmware is latest according to serial number via kies, but it gave me error.
i know it's from hungarian market, but don't know which exact part of it (branded or not).
don't know what previous owners did to it, and don't have backups of original efs or anything original.
i just want to make it work, don't care much about custom firmwares. i'd be happy even with unrooted stock... just for it to work!
i have no ideas what else to do.
anyone?
finally, as i couldn't resolve the problem, i returned phone to 2.3.5 and sold it as is.
thanks to all people who tried to help.
cheers

[Q] [sola] random hang/reboot, HELP needed

Hi guys!
I've got a Xpera Sola a couple of months ago, and it keeps random freezing and rebooting quite frequently,
at a time base of a dozen times a day, which make it unusable.
I've been waiting for new ROMs and hoping for a cure, stock 2.3s, stock 4.0s, and cm9s, but none of them works.
The only difference between stock and cm is stock do HANG/REBOOT but cm just HANG and drain battery.
While lost faith in new ROMs, I tried to figure it out myself, and here is what I found:
No reboot/hang in airplane mode (so it's the radio?)
No reboot/hand when ADB is pluged (so BAD news!)
My configuration:
Bare ROM, no additional apps.
GSM networked SIM card / no SIM card, makes no difference (I have no WCDMA card so can't test)
Wifi / no Wifi, makes no difference (maybe hang more often with Wifi on, but I'm not sure)
SD card (2G) / SD card (4g) / SD card (16G) / NO SD card, makes no difference
CPU governors, no difference
wake lock, wifi lock, accquired with terminal in cm9, still hang
Any feedbacks are welcome, need your help!
Thank you very much!
some updates:
the problem still there, tried cm to 213 and .54 Italy/China and munjeni's MIUI.
getting hung when using the phone only happened in stock or stock based roms, not in CMs.
stock based roms seemed to have a watch dog to reboot the phone in a 2-5 min interval, but not sure whether it's in kernel or in rom.
guess the hang happened when awaking from deep sleep mode, and no deep sleep no hang (such like when ADB is active and deepsleep disabled).
forget one thing:
witnessed one hang issue in air plane mode.
I assume you are on stock ROM, this is not normal. Did you try repairing with PCC?

[Help] Lost IMEI after update to , and downgrade

Well, received my Sony Xperia Z Ultra C6833 a couple of days ago.
Received a notice on the OTA, upgraded to 14.1.B.2.257
I encountered random restart issues whenever Wifi is activated, so I thought, fine.
I finally have access to my computer, installed the PC companion, it prompt me with a new 14.2.A.0.290 update.
Again, I updated my phone, hoping it'll fix the Wifi problem.
After restarting, I did a test, as usual. Wifi problem persists, and what's worse, a new problem. Wifi and Playstation 3 SixAxis controller connected using bluetooth didn't play nice, caused my phone to reboot.
I know a lot of people downgraded the firmware back to the previous version, with NAN backups etc.
And some even managed to restore their IMEI back to normal.
But for my case, I haven't root my phone, attempt to downgrade it using Flashtool, lost my IMEI.
Seems that I have no choice, but to return it back to 14.2.A.0.290 praying that it works, and I still can't see my IMEI.
No, I don't have a NAN backup. That's the part which gave me a headache. I've messed around with HTC one X (a year ago), never had this problem problem before, and it's something new I've learnt from you guys today.
Tried cyangenmod's boot.img, doesn't do me any good.
Anyone managed to recover their IMEI here?
Otherwise I might have to get it back to the dealer for a replacement.
Update: Thanks to krabappel2548's guide, I've managed to flash it to 14.2.A.0.290 again and got my IMEI back, but SixAxis still won't play nice with Wifi, and the problem with random reboots while Wifi is ON still persists.
we have the same issue, mine happened during the old update, after ota wifi gets stuck, wont turn on and reboots the device. upto now its still not fixed. 3 updates have passed and still the issue persist. hope you find a fix it will help me too. tried everything from downgrading, flashing custom rom,kernel, upgrade, unlock, relock but still cant fix it
I guess i'm not the only one then. I can live with the wifi issue for the time being as long as i stick to using data. But i fear it's going to affect tethering should i need that.

Read it the moment I discovered that my IMEI is missing.
I tried reflashing excluding the baseband, doesn't work for me, right after i realized i have a missing IMEI.
Read up on the android emulator, but haven't tried it, as my computer is kinda old, took forever to run it. Will try it once I get my hands on a faster computer
Bah. Crashed when I tried to use my qx100 which i've just received. Haha. Anyone else has any fun with qx100 and z ultra combo? The Z ultra almost reminds me of my ex-girlfriend.
Meanwhile, I can't wait for kit Kat, and hope they really squash these bugs
The best thing would be to contact Sony and make them aware of this bug. Losing your IMEI by simply updating should never happen and it's quite a serious bug.
Actually i lost it after downgrading. Downgrade is simply because of phone keeps rebooting after I turn Wifi on.

I certainly hope so too.
Hope it fixes the rebooting issue with WiFi enabled.
Or the Google Play Edition port if it does fix the problem too
Anyone tested the new update yet? Does it fix the wifi issues with crashing/rebooting?
ok so i purchased my phone on amazon and got it somewhere around feb 25th, i got a message on the phone to update software so naturally i did, then i discovered what rooting does and i decided to follow some youtube instructions to flash my phone to an earlier firmware the link wasnt working so i found another which was C6802_14.1.B.0.475_GENERIC Hong Kong.ftf after flashing this i lost my imei its all zeros and i then tried flashing C6802_14.1.B.1.526_M3dD0g.ftf with no luck so im trying to find out what the updated software was that i must have downloaded when i first got the phone given the date i had recieved it im thinking that the 14.2.A.1.142 is the correct one that i must have updated to, i was running version 4.3 jelly bean before all this happened i also have this problem where everytime i turn off the phone and turn it back on it is in the chinese writing again and asks me to select my language again anyone know what to do short of return the phone while i still got time my internet is extremely slow im tired of it taking 4 hours to load a new ftf just to find out its not the right one ive heard some where hving success with the 290 getting their imei back but im thinking thats the software they started with or updated to to get it back so i have no idea which one i started with or which one i updated to all i know is the date i got it and that possibly its the 14.2.A.1.142 looks really familiar im downloading that one now so we will see what happens and i also read something about flashing excluding the basebands so if that is part of it please make it as clear as possible im obviously a noob but im learning quick
Pleas dont ask the same question in multiple threads.
See my reply to the other thread you necromanced

Wifi and Hotspot Problem

Hi everyone,
I have a really annoying issue for a while and I hope someone can have a suggestion.
When i turn hot-spot on, my phone freezes and reboots itself, so i cannot use this feature, however if I connect it to my computer i can share my data by Bluetooth.
More annoying issue, if I try to connect to wi-fi when my data is on, it freezes and reboots again and after that I can connect, but if I disconnect somehow, it reboots again. When I turn the airplane mode on, there is not a problem..
Has anyone of you experienced such issue?
Thanks
Sounds like a corrupt system, probably network driver or baseband
SInce you don't mention anything else I suppose you're on stock ROM , still locked bootloader, no magisk and all that. Simpliest way if your not familiar with ROM and boatloader handling is probably to do a total reset to start with followed by an update. Xperia Companion can be used.
If you're famiiar with ROM handling you may get the latest ROM from XperiFirm which you flash with Newflasher

Hi pergoteborg,
Thank you a lot for your concern.
You are right, I am on stock ROM. I have tried to do a total reset, but it didn't work.
Moreover, I am living in Italy and using Tim Italia, few days ago I was in Austria and in there I did not have any problem when I connected to an Austrian operator. I tried with a different TIM sim card in Italy, it was same. I will try with a different operator as well, but I have not had time yet.
Does it pop up anything on your mind about what could cause such a strange problem?
Thanks in advance.
Regards
