[Q] Random Crashing, and lagging Gt540?? - GT540 Optimus Android Development

I dnt know whats wrong with my phone but ever since i updated from 1.6 to eclair my phone has randomly hung then reset, id assume this is a firmware problem since this phone is fairly new, so is there any way to Fully reflash rather than reflashing with these Baltic and other rom partial flashes?? the firmwares i have tried are Baltics ( was stable but not what i wanted), Uk Open( stabilish but not what i wanted) and then Australia( sorta what i wandted, but very unstable) in that order, australia's rom really started the problems, it was very unstable for my phone and i have not been able to reverse the instability by flashing back to baltics, iv tried everything, factory resetting did little to no differance with these problems, so any advice or solutions would be helpful and welcome! thanks!

Well all the roms are stable for me. You are using someking of app that ****s up ure ROM or just doing something wrong while flashing the ROM.

Don't forget to hard reset the phone. Before and after flash to be sure. I have Baltic and the phone is very stable

As far as im aware the flashing process is not the problem, and im definatly not using any random apps, for instance i may have just done a hard reset on the ausy rom, then typed in all my settings added all my accounts, nothing out of the abnormal and then sometimes it will either blink the screen then hang then reset, or will show up with a " unexpected stop error com.android. blah blah" and will drop my cell coverage and then get the reception back then come up with the same error.. this will continue till i force a hard reset again.. its damn annoying

I'm using the Australian ROM...is very stable. Haven't experienced any random freezes or crashes. Try reflashing your phone.

Strange Captivate issue

OK.. First of all I want you to know that I'm not a n00b and that 99% of the cases I know what I'm doing with my phone but this is a weird one
Problem no.1: The simcard keeps on "disconnecting", resulting in disconnection from the network. Since the first seconds I start the phone it does this. Sometimes it doesnt even accept my PIN as being incorrect, but in the notification bar the SIM+! icon disappears for a moment. This is after I screwed a ROM and returned to stock using the OCD JF6.
Problem no.2: It wont master clear! No matter what I do, it wont do it. I tried since the first second when ODIN detects the phone. I tried it when it fully loads the ROM, it just wont go.
Background: Before, I had installed Froyo JPA i9000 ROM with Reoriented kernel 2.1.2 (voodoo lagfix+color,bln). Everything was soooooo fast on that ROM (with around 100 apps installed) but I wanted to theme it. So I tried to deodex it using xUltimate. I followed the (logical) instructions found in a post here and it didnt want to boot anymore... well, it did but in a FCs symphony.
I did what I believed is right and I returned to stock but I forgot to pull out the SIM card... then these problems appeared.
Gimme a hint what could I do. I'm asking first here because a working PDA without a SIM is .. acceptable but a totally bricked one is worse so before I take any steps further I need your opinion.
Thanks a lot.
No one?

Problem 1: can probably be fixed by reflashing stock with the SIM card *not* in the slot (that's about my only guess, never seen that).
Problem 2: master clear must be done with the phone turned on *NOT* download mode. the phone must be fully booted with adb debugging enabled in settings.
xUlimate: it's a poorly written application and it's success ratio is probably about 50/50, another tool to look into is auto-deodexer. Also, both the framework AND the system apps need to be deodexed to have everything play nicely (gtg taught me this one)
id experiment. from what i gather you were able to flash jf6 but it was a bad flash. does it still have download mode? maybe try to flash again and then try to master clear? maybe try to flash another rom, then try to flash back to stock?
this doesn't sound like anything anyone has seen before so your best bet is to just try something.
Thanks a lot for the replies guys!
The master clear was tried from all phone statuses (booting; finished booting; after the phone operated for a while) except download and recovery (i know is not suppose to be done from there).
I did reflash to stock without the SIM, same issue.
I will try flashing again some other rom. I'll try more and ill post the result here

OK, so, it seems that for some reason, after stock restore there were still remaining of XEE CSC in the phone..
I loaded the JPA back and now is all fine.
I am having the same issue, unable to clear with CWM or odin, or within the OS in either the stock rom or axura 4 or 5...
Can you please elaborate on your solution?
CSC looks familar to me, thats an ODIN file right? If so, what part of the phone would that be (kernal, modem, OS)?
What do you mean by load JPA? Odin package or CWM? WHole rom or specific parts.
thanks...this has got me stumped
Well, my issue is that I cannot use 2.1 anymore (any 2.1, tried stock Captivate and JM8 from i9000), I don't understand what is wrong but my first bet is that the /efs partition got changed in some way when I loaded JPA i9000 ROM.
Froyo works fine, any ROM I load give me full functionality but on 2.1 the SIM gets disconnected all the time and after a while the phone reboots by itself. Just to make it clear, I never had the usual Captivate reboot issue, it started when this SIM problem appeared.
Note: my product codes are fine, in both nv_data.bin and nv_data.bak the product code is finishing in ATT and my IMEI is available in both 2.1 and 2.2 and is correct, so no IMEI corruption here.
Could someone give me a hint?? Would flashing to stock with phone EFS clear help?

[Q] Please Help. 3 Day old SGS behaving very strangely

Hello everybody.
I am having serious trouble with my phone and I was hoping some of you might be able to help me out.
I just bought my SGS 3 days ago. It came with android 2.1.1 eclair installed.
I had read that that version was not the best ( the first thing I saw when I opened the phone actually was an error screen, and the lag was horrible) so when I got home I decided to try and upgrade it using the official software for it (Kies).
Unfortunately Kies would simply disconnect my phone when I told it to upgrade, after which it would ask me to upgrade again >.>
So I decided to use Odin to flash one of the newer 2.2.1 versions.
I flashed a 'JS3' version with a repartition to 803 pit , but it crashed after rebooting with the dbdata error (which as I learned later was caused by not flashing a full firmware).
I flashed JPU after which worked great. It was fast and responsive.
However my phone kept crashing. Whether on standby, using apps, or just trying to dial a number, it would freeze, start vibrating, and sometime reset, other times just stay frozen until I force shut down it from the power button.
I flashed JS5 afterwards, with full cache clearing, factory reset etc. Still crashed.
Then I tried flashing Darky's 9.2 Ressurection. Loved it but I couldn't even set up my google account because it crashed constantly.
Then I went back to what I believe is the current official version for my location and carrier (Vodafone Romania), JP9 .
After flashing it didn't crash, but after a while (one night), it started crashing like crazy, even wound up with weird gray lines and a freeze in the morning.
I was hoping someone here might know what is wrong with it. I already sent it back to be serviced but I am thinking maybe I broke it somehow and would like to know how so I don't do it again.
The phone is network locked, which I later learned is usually a bad thing for flashing, unfortunately I didn't know about that when I started.
well first of you want to remove the network lock so try these:
http://forum.xda-developers.com/showthread.php?t=761045
http://forum.xda-developers.com/showthread.php?t=913681
next step is to register on www.samfirmware.com (its free) and here is where you will get all the latest official firmwares from samsung..
what you want to do is download (XWJS5) with all 3 files and PIT and flash that through odin with RE-PARTITION..
Before you do that, put your phone into recovery mode (volume up + Home button + Power button ) and do a factory reset / wipe cache ect...
so when you have done that and flashed the new firmware. let me know what the outcome is..
another thing.. ALWAYS MAKE SURE KIES IS CLOSED.... EVEN IN THE ICON TRAY... AND MAKE SURE DRIVERS ARE UP TO DATE.
other than that you shouldn't have any problems
hi, thanks for the advice.
I already did most of that however. I did a factory reset numerous times, and I also did a full repartition flash more than once, to no avail.
I am waiting to get it back from warranty service now but I am wondering what went wrong.
Was it broken when I bought it or did I damage it somehow by trying to flash it while network locked ?
flashing with network lock wouldnt make everything force close. the worst thing that could happen when flashing with network lock is not picking up a signal and possible IMEI corruption.
i think you may have just flashed the wrong ROM, it happens to us all, but the more you do it the more experienced you become and you soon learn methods to restore things..
dont worry too much it will be fine when it comes back from samsung, just be sure to read up properly if you have any doubts.. or ask a question first you will get a reply quicker than you can Unbrick your phone..
My phone seems to hate the 803 pit file. Lots of force closes when I used it. Try using 512, see if that works any better.

[Q] Galaxy S i9000 won't factory reset and force closes frequently - now with logcat

Hello all,
please forgive me first of all because I've had very little sleep due to this issue. And its a long thread, but more detail is better generally I believe.
First, some background, and unfortunately, it starts with my wifes phone.
My wife has a Galaxy S GT-i9000 on Orange in the UK. She has had it, probably about a year maybe at most. She has a few apps that she has downloaded but nothing major and on first looks when I got it nothing I expect would cause this issue, just facebook etc.
My wife came home and said, my phone keeps coming up with a message saying force close. Ahh, I thought, some apps gone nuts, but alas, it appeared to be many apps including Maps, Google Upload (I assume this is a system process), Facebook Katana and many more, probably about 20 Force Close messages pop up one after the other and it lags whilst trying.
Odd, I thought, I also noticed the icon for one of the apps on her homescreen had changed to the default White and Green one with the android on it.
I suspected something had gone wrong (obviously), I asked if she had rebooted it and she said she had. So, I rebooted it again, just incase. Same problem.
I then thought it might need an update, it was running official Kies 2.3.3 (or was it 2.3.4, I forget) so I plugged it into my netbook and ran Kies, had to update that as it didn't have the latest application update. I then started the firmware update, after backing up the phone using Kies.
Halfway through the update, Kies popped up a message saying something went wrong and that I had to unplug the phone, take out the battery and reboot. Odd, I thought as the phone was telling me to not doing anything. I waited a minute, nothing further happened, so I did this. Then I got the Black Screen of Death with the phone, the dots and the computer screen.
Crap!!! I thought, I managed to get into Download mode, and reflash it using what I believe was an official ROM using Odin. I then rebooted, and found that it STILL had the data on it and it STILL was doing the force close. At least I had it back to "working" though so I was mildly happy.
I then did a factory reset using the menu system, erased the USB storage (there is no external SD card in her phone) and rebooted, still force closing but prompting me to setup again. Weird. I went through the setup slowly, as every second or so a force close would popup, then when I completed the setup (which still had the wifi settings, account settings etc in it) the System Setup crashed with Force Close. I then rebooted and got to the Home Screen, but still crashing.
I rebooted and used the recovery screen to clear the cache and factory reset, despite the warnings I will lose everything, nothing was wiped.
I tried to update using Kies again but it tells me that the firmware/device is not supported. I am now trying to see if I can use Odin to install a Kies supported firmware. So that I can then try an update using that again.
Anyone got any suggestions, at present, my thoughts are, I was going well within the realms of warranty up until I reflashed it using Odin to try and get back in as I'd only used Kies to update and the issue "just started happening" without my missus doing anything.
There are no signs of damage on the phone and she tells me it was just sat on her desk all day.
So, my question is, what now? I'm of the opinion based on the above that if I can't reflash a warranty supported Kies update, then maybe a custom ROM will be worth a shot to see if its a hardware failure or if its software. I just have never had an issue like this with my HTC Desire and I've ran many custom ROMs and standard ROMs on it.
I do have the .tmp file of the update Kies downloaded, and I also have a Binary folder which has some file inside a couple more folders but its not a .tar or a .zip because when I try renaming it (after a copy) it won't open.
So, suggestions on a postcard, thanks if you got this far through this nightmare. All help massively appreciated.
Edit: it appears to be the same issue as this: http://forum.xda-developers.com/showthread.php?t=822238
I'll try some of their suggestions. Today I also did the *2767*3855# today which I found after a bit more searching. Same problem after a reboot. Force close and data still there.
I've tried and tried again to do various solutions for this, I've even ran a logcat using adb to see if I can see the problem. I suspect its a Dalvik Cache issue in that its unable to write to it for some weird reason.
I've downgraded it to Froyo following this guide: http://forum.xda-developers.com/showthread.php?t=1100906
It now detects in Kies and offers me a firmware upgrade. I suspect it will die again though if I try due to this Dalvik problem.
Wiping cache does not wipe the cache. Everything still appears to be there on reboot as mentioned above.
Here is a copy of the LogCat with Java errors all over it: http://leenukes.co.uk/downloads/logcat1.txt (its quite long)
I guess nobody knows. Today I will speak to Orange to try and get it fixed or replaced.

We've been told it is beyond repair. We will see what they say when we go back into the shop. Its still in warranty so I don't see why they won't replace it.

I have a friend with a Galaxy S from Orange Romania and suddenly the phone kept showing Force Close on every App. He had 2.2.1 if I remember right. He whent with the phone to an Orange Shop and they only do a factory reset but data was not wiped.
So what i have done for him:
- start the phone in Download Mode
- start Odin with repartition check and XXJVT (2.3.5) firmware with 3 files (code, phone and CSC) + pit file .512
- after reflashing the phone does have all tha data, so i resarted in Recovery Mode and done a Factory Reset and a Cache Wipe
- i flashed Speedmonde Kernel k16.10 and do again from Recovery Mode a Factory Reset, Cache Wipe and Davlick Wipe.
On reboot the phone was CLEAN. No force closes for a week now.
Sorry for my English hope it helps!

Sound advice there mate, other thing I would have done is in recovery mode before the ODIN flash I would have format sdcard, making sure you have removed BOTH the external sd and the sim card, as it can wipe them as well.Then flash through ODIN as per instructions above.
Using JVT I would flash either speedmod or semaphore 2.1.1 which I personally use.
Happy flashing!!
turns out it was water damage and some parts corroded.
Its going to be claimed for on insurance.

Hello all,
the phone came back from repair yesterday, yay!
the phone now however, doesn't appear to lock onto a mobile signal for very long. Boooo!!!
After sending off for repair using insurance, we got the phone back yesterday but it now appears to be broke in another way. It won't lock on to a mobile signal, wireless is fine but data network and sometimes just mobile signal is patchy and keeps dropping.
I've just reset it to factory defaults, same problem. What I did notice, which is odd is that since it came back from repair, its now unlocked and I can put another networks SIM card in it, same issue there too so I know its the phone now.
I'm going to scour the forums to see if anyone else had/has issues like this, it is running the latest firmware now and a full wipe really did fully wipe it this time, as opposed to last time with its issues due to water damage. One step forward, two steps back?
Its going back to the insurance company. Especially as Orange were suggesting that we pay £70 for a new handset.
Absolute fool I had on support today, yesterday I at least had someone sensible.

Sounds like a modem issue, where the techs at Orange put in the wrong modem for your firmware. I did the same thing when I upgraded from Froyo to Gingerbread.
Alternately, it could be a broken external antenna connection as a result of the corrosion from the water damage. Google "no signal fix" and look for a site that ends in .uk
Just a thought for others who come across this problem.
I

Experienced flasher, soft-bricked my Note 4 real good.

Hi guys and gals.
I've been flashing roms for years and I've soft bricked my devices dozens of times and have always been able to recover, except this time.
I was running Cyanogen mod 12.1 and all the problems started happening after a nightly update. Basically, the phone got super laggy and eventually started random rebooting. I thought it was a bad flash or something was wrong with the latest update so I did a clean wipe and flashed another rom, same thing happened. Eventually I Odined back to stock and it ran fine for a few days but the problems came back. Now the phone won't even finish boot anymore. I used NAND erase all in odin and and reflashed again, it seems to be better since it wont reboot its self anymore but I can't get past the T-mobile splash screen. Last night I tried reformating the NAND using a PIT file but I kept getting "Secure check fail : PIT". I was starting to thing the problem is hardware related but it won't RR in download mode and I think its too big of a coincidence that it happened after the Cyanogen update. Any ideas?
My first and always main advice is that if you are unsure about your hardware the first step is to Odin back to stock. The reason is because it is a bit for bit rewrite back to the way the phone was intended to be run as long as you do a factory reset from Stock Android Recovery before it boots. This is how your phone was when it came out of the box and it is a great way to check if it has a hardware issue by looking for bad behavior when using the original drivers.
If you flash back to stock completely clean and your phone is still acting crazy you might have bad blocks on your NAND, you might have issues with your RAM/CPU, or it might just be a loose hardware connection from heat or impact. But you can only truly diagnose those from Touchwiz because the drivers are first-party, not reverse engineered to be compatible. If you can reinstall all your apps and use it normally for a week then your hardware is good and CM was the problem and you should try another AOSP build.
I am on the 09/09 Nightly for CM and I can tell you that I have no lag or issues on my device at the moment for what that is worth. Good luck!
Thanks. I might just send it into samsung and see what happens.

N920C Randomly freezing then rebooting

It happens randomly when using the phone (it doesn't happen when it's locked). The phone just freezes then restarts randomly.
I tried to find a pattern when this is happening, and found there isn't much of a pattern, but it won't let me add a fingerprint lock (crashes after the 3rd / 4th reading).
I've tried to factory reset and clear cache. I'm running out of options and am preparing to flash a stock ROM via Odin. I'd like to avoid this, since it'll trip knox and this is a new phone so I wanted to avoid flashing anything for now.
Any suggestions, ideas?
I'd say this is a kernel related crash, since it doesn't give any error, just goes out. But I hope I'm wrong.
Baseband: N920CXXU2BPD5
Build Number: MMB29K.N920CXXU2BPD6
Knox untripped.
EDIT: This seems to be a rule: it always crashes when I get to 32% of adding a fingerprint lock.
Here's an update:
Tried flashing other stock ROMs for other regions, still the same problem.
Flashed a custom kernel, still the same problem. -> Not a kernel problem
Flashed TWRP and used it for some time (to test if the phone will do the same). No problem whatsoever. I'm convinced that this is a firmware issue then.
Tried flashing every possible combination of everything. Nothing seems to have any effect. This isn't a software problem.
It's probably a faulty motherboard. The rebooting subsided though.
I'd also like to add that the S Pen holding area (the place where the S Pen is kept inside the phone) has a specific electronic smell (kindda like the soldering smell, but not quite). Really weird.
I voided my warranty by flashing stuff, so I'll probably be looking at a motherboard replacement if anyone's wondering.
Do u have xposed install?
Nah.
I've been running the stock rom for 90% of the time.

I'm almost certain it's a faulty motherboard.
