[Q] Constant password prompt despite flashing/resetting

Hi Guys!
Well, basically..
the problem I have is just like in the title.
My SGW I8150 keeps constantly prompting "Enter password to unlock" (phone is on, at lock screen) despite numerous hard resets,(got CWM 6 recovery) formatting,clearing cache,dalvik etc.
it all started when i set up a short password for the lock screen.. (rom was stock, rooted and cwm 6, if not 2.3.5 then 2.3.6)
googled a lot, read a lot, no avail.
later flashed ics and had a week of struggle. mainly because of battery draining fast.
AND now, since I wanted to return to stock, because I do, the reason is the same. battery lasts the longest on that stock rom. I do a lot of texting calling music, pics and occasionally internet. 2 days battery lasted.
So i downloaded bagux-project-v1.4, rom had mostly everything i needed and installed it and still the same problem. Of course the initial setup settings always were present but after i completed them and the second the phone locks, the problem still persists..
rebelrom 3.0 as well shows the same..
only cyanogenmod rom's like "ancora beta3" or ics or any other rom which doesn't have the baseband / kernel (correct me) something in common shows this problem.
Also, no "forgot password" (e-mail help) does not pop up at all. only "emergency call".
I flashed other roms; Cm7 & arco68 CM9 and some other ics roms. THIS PROBLEM DOES NOT HAPPEN ON EITHER ICS version..
I have no idea why is this happening only on the roms generally similar to stock. 2.3.5 , 2.3.6 , 2.3.7
Please try to help if You can

Try formatting the system cia CWM before flashing. See if that fixes your problem.

I said that before.. i did factory wipe/reset ,2nd option cache as well from cwm6 as well formatted the system, cache, dalvik, sdcard,onboard storage. one by one. did factory reset by using code *2767*3855#, still password prompt. downloaded a stock rom from sammy, flashed it via odin, still password prompt exists.
In my opinion, some data (specifically that unlock thing, password prompt) is left over on some piece of memory in the phone even though wiping, flashing and clearing has happened..

Hello... Please..Could anyone help me? Show me a way to do a FULL, but I mean seriously a COMPLETE WIPE of Data from each memory part on the motherboard.. Or at least something like that ?
Like I said, this happens only When the base of the rom is gingerbread..
Custom rom's/stock based on gingerbread when installed and the lock/power button is pressed and then again to turn the screen on, right away shows the password prompt...and that's where it all ends..
I had to install ICS, which is buggy and drains battery fast and since t's a whole new base to start from, the problem with password prompt disappears..
I don't know what to do anymore.. I'm not a noob at this because I have rooted MYSELF and flashed roms and other stuff to Samsung Gio Samsung Galaxy S II and Htc Desire-Z (a7272) and now I have my wonder I8150 and this weird thing just happened..

[Q] Xperia S freezes randomly

Hi everyone.
I'm having a little problem with my Xperia S, it's kind of new (2 weeks of use).
When I'm using normally the cellphone, everything works great, but if don't use it for a long time and I grab it faster and unlocked it, sometimes the cellphone freezes! Well, not exactly freezing, it still works but VERY slowly, almost like freezing. I can't turn it off with power button, I had to user Power + Volume button to turn it off/restart it.
That happened in first week, so I unlocked bootloader and flash it another kernel (advanced stock kernel), and the problem was there.
Later I made a backup of the firmware (I updated to its last version with PC Companion, ICS btw) and flashed a custom ROM (XTXperience 4), and the problem was still there.
Yesterday I flashed a Generic ICS ROM downloaded from XDA Server using Flashtool, everything went normal until today, when the problem happened again.
I've been searching here in XDA and Google and still nothing seems clear of what is causing the problem, if it's the sim card or maybe a hardware problem. I'm going to relock the bootloader today, and I will try to repair the phone using SUS.
What is causing the cellphone to freeze? Hope someone help me with this. Thanks in advance!
btw, sorry about my english, hope you understand most of what I wrote

Well in my experience,
The phone freezes because it is too hot,
Or the RAM memory suddenly drops.
I mean sudden ur phone's RAM memory is 0.
I'm not sure too.
But I think reflashing the kernel, or flash other kernel will fix the problem
Try it

What ics firmware did you flash? And did you do a complete wipe when flashing?
Sent from my Jellybean Xperia S

I've flashed other kernel and yes, I do a complete wipe when I flash another ROM, via Flashtool or CWM.
I've been thinking of rolling back to GB to see what happens.
Yesterday my phone freezes like 2 or 3 times in less than 15 minutes. First time I reboot the phone and it was ok like 5 minutes, then it freezes. I reboot again the phone and happened again.
Its not even hot or using a lot of RAM, it always has like 250 or 200mb free

Did u play with CPU settings?

No, this is happening since the first boot of the phone. When I turned it on the first time it happened, and I had to search how to force a reboot because I didn't know how to do it LOL
It doesn't happen very often, but when it does is very frustrating!

Try flashing a new rom, but wipe the system partition too? I always do that to ensure a fully clean install.

I'm thinking in flashing a non based stock rom, like CM or MIUI, because I flashed XTXperience before and the freezing happened.
Oh, and the problem still exists. I believe Wi-Fi connection maybe it's the problem, I'm testing some things right now.

Had this too using Supercharger (by zep) but after few setting it's gone. Maybe you should try to run the script ?
It was with stock rom and advanced kernel v15/16.L

Well, I was on 6.1.A.2.45, I relocked the bootloader and an update changed the firmware to 6.1.A.2.55 using SUS without wiping data and the problem was still there, so I repaired the phone with SUS, it erased everything and the problem was gone for like 2 days. Today it happened again.

Well, I Supercharged my ROM now, which setting do you use to fix the problem? I'm still having it.
I even flashed a CM10 based ROM and its still happening! I think it's a hardware problem

Hi, did you manage to solve the problem? I'm having similar issues like you

[Q] What is wrong with my Gnex?

Hey the Problem is the following:
3-5 random reboots every day
restarts during every phonecall after 1-3 Minutes
freezes when in standby, cant turn back on -> need to take battery out
often slow, especially when switching apps. or when typing
I have tried stock 4.3, CM10.2 recently and before that CM10.1 for a while.
I already send it in but they only said my battery is broken.
Is it possible that all my problems come from this?
I rather think my flash memory is broken? What you think?

Since yesterday I am facing the same problems you are describing. At first I thought it was a bad flash or something like that. Clean installed various 4.3 costum roms and it's always the same.
Right now I will look deeper into it since the phone is unusable in that condition.
If I find a solution I will comment.
Best regards
Edit: Okay, works again flawlessly. I simply flashed an nightly from carbon-rom and the lags were gone. Hope it helps. What exactly caused the lag I don't know. For now I am staying on 4.2.2 Carbon as it is my favourite rom anyway and I will wait till there are stable 4.3 from carbon.

Are you sure it's the phone and not an app?

Not pretty sure, but it still occured after countless factory resets, wipe cache, wipe dalvic cache and wipe system via TWRP.

Have you tried a clean install without installing apps to see if you get a reboot to eliminate an app as a possible cause?

Yes I did. I only flashed for example newest PA and their PA Gapps.
So far I resolved it by "downgrading" to a 4.2.2 nightly from carbon. The lags are completly gone. I will stay and wait till carbon has stable 4.3.

why dont people try stock when they are having problems? going from 1 custom rom to the next does not prove it is the phone.
please fastboot flash the stock rom and do not restore any apps/data other than say your google acct

Already did that.

I am having the same/similar problems with my GNex too. Specifically bullets [1-3] from the original post. I am running unmodified yakjuux and have tried with just my google account with no other apps and the same problem exists.
Mine makes a noticeable "click" sound with a vibration followed by a reboot.
It usually happens during calls and after it boots the phone call log shows no record of the incoming/outgoing call that just happened. Its like a blue screen of death for android!
I have sent the phone back to Samsung's warranty service 4 separate times and each time they reported no trouble found in the completion report. They just factory reset or put an older version of jelly bean back on the phone and send it back to me with some notes of PRL updates and other nonsense to make it seem like they did something to fix it.
Does anyone have any suggestions (logs, adb, etc) how I can help prove to Samsung/service absolute that the phone is a lemon (other than trying to video tape the phone hoping it reboots - because that is the last resort)?
I already escalated to executive customer service and they refused an exchange because the completion reports show no trouble found :crying:
Thx!

well... I also have this problem.
First happened when I flash Cm10.2 nightly (don't remember which one).
Then I flash PA, or whatever... Looks like the random reboot relating to notifications? It's usually happened when whatsapp notification coming in, but not always.
But a few weeks ago I flashed stock ROM rooted (via TWRP, not fastboot).
The problems solved. No random reboots anymore. Then today I tried latest CM10.2, and it happened again... Wonder why... Looks like it's a very rare problems.
Interesting to see someone having the same problem...
Now I want to flash stock ROM via fastboot to check if it'll fix.
Btw, I can flash directly to CM 10.2 from 10.1, can't I? Or I should flash 4.3 via fastboot first?

I believe CM offers an upgrade option somewhere in the system settings. Unless you want to wipe your phone and flash directly to 10.2 in which case I do not think you need to flash stock 4.3 first. Maybe just do a reset within 10.1 before you flash CM10.2 via whatever recovery (clockwork etc) you are using but even that may be unnecessary.
My 1 year warranty expires this month so if I can't manage to get something out of Samsung I am going to play around with flashing stock 4.3 as you suggested. I have tried converting yakjuux to yakju in the past but still saw the problem then which made me revert back to yakjuux so I could send the phone back for service).

Wifi issue on AOSP Roms

Hi guys,
I have had the s2,s3,galaxy nexus,original note and i am used to flashing and modifying,but i have a serious issue with the note 2.
The problem is whenever i flash AOSP rom(cm,aokp,pa) my wifi would not connect.It shows the name of the network and when i click conenct nothing happens.Flashing back TW rom fixes it,wifi works like a charm. I've done full wipes but it doesn't seem to resolve the issue.I tried different kernels,but that doesn't help either.
So I am stuck at TW roms and i hate that.Anyone has any ideas?

You can try options 2 and 3 from this thread.

Thanks for your reply,but i tried this and it didn't solve my problem.

Anyone?

I Have the same problem...

Not sure that it will help you but I read something yesterday about this issue.
The solution was to NOT restore your Google profile during first boot so you should full wipe and try again.

This actually has nothing to do with the problem.
After a few days I finally found the cause ,and therefore,a decision to the problem.
It is the bootloader from 4.3 sammy leaks.It seems that this new leaks(probably the reason being KNOX) cause malfunction of wifi in aosp roms.What i did was ODIN flash stock MG1 from sammobile .This brought back stock recovery so i had to flash TWRP again and it solved the issue for me.
Before that i had tried changing roms,kernels,recovery,modems and nothing worked so I am pretty sure it is the new 4.3 leaks bootloader.
Some people will say that it can\t be the issue because they are using 4.3 sammy and do not experience the same problem on aosp roms,but i think thats because they flash it through CMW ,which doesn't change bootloader,while flashing through ODIN does.

With my Note2 this is not the solution. I've tried everything. What you said, move file "pit" ..... but nothing. I can not connect wifi. The connection does not appear region Spain, and have opted to choose europe, but neither. I do not know to do. CM 10.1 also does not work WIFI. In Stock ROM or Custom ROM works fine fine, but in ROM CM 10.1, 10.2, AOKP don't work.

[Q] Unknown problems there...

First of all, my English is not that good, so I hope everybody understand me
I'm a flashoholic (i think this is the right expression); i flash a new ROM almost every two weeks. And, from some days ago to now i'm experiencing some problems. Here's my problem:
Problem: my phone "stucks" when I let it locked for more than some 5, 10 seconds. I lock it now, and... dead. I have to press the power button until it restarts. My phone is having trouble to find operator's network and it's EXTREMELY lagged too. It almost stucks when i try to write something on the keyboard, or draw/write my passwords on my lockscreen.
Here's my "ROM timeline", too:
ROM Timeline: MIUIBrazil v4 [4.1.2] >> P.A.C MILESTONE [4.2.2] >> TigraROM/Hurricane [4.3 leaked] >> MIUIAndroid v4 [4.1.2] >> MIUIBrazil v4 [4.1.2]
Underline = i think that this is the point
Bold = problem started
So, let me explain my history: flashing ROM's as always, I decided to change things a bit and go AOSP for a while. So I flashed P.A.C. Milestone. Actually, I've flashed first the Nightly version, but it was a bit unstable. I went to P.A.C and everything went fine. But, hey, where are the Samsung functionality? I missed it. So, after some trouble finding the right ROM to me, the 4.3 from Samsung leaked. I tried it, then. First the Hurricane, afterwards the TigraROM (Note 3 functions ). And it was ok, but was lagging a lot. Too much launchscreen redraws to handle, so I went back to MIUI (not the first MIUI on the timeline, because I've decided to go right from scratch), and then, i've noticed a lot of problems.
It was not booting up.
I've flashed A LOT of ROM's trying to solve this problem. What it was? EFS folder. I went to the TWRP file manager on Recovery and noticed that the EFS folder was empty. And no backup. I went crazy until i found an old backup stored on my PC. Restored it right away, and everything was fine for a while... until it started doing some strange things like extreme lag and dead when locked.
And, when I went to recovery to look again to the EFS folder, it was always empty... i restored it again, again and after locked... BAM, disappeared. But some strange things are happening, like:
My bluetooth doesn't turn on.
My IMEI was fine, even with this EFS showing and hiding like that.
I'm almost finishing. Let me put here some basic questions that I know everyone will ask:
Q: have you tried to wipe everything and go from zero?
A: yep. It didn't worked.
Q: is your IMEI ok?
A: yep. But some things that are on the EFS folder doesn't wok, like Bluetooth. The MAC address of the bluetooth is there, but it doesn't show up when I write *#*#232337#*# on my Phone app (this code shows up Bluetooth address and try to turn it on... to me it tries to turn on forever).
Q: do you know that thing about the new modems? Click here to go to the post
A: yes, but only read it when i've had the problem. But i've restore that backup, and it was from the original ROM. So it doesn't seem to be this, because the backup was before this leak. Very very very before, actually.
I hope you guys can help me, and that I don't need to go to the Samsung support with the phone wiped. Thanks,
~imatheussm

When you say you've tried from zero, do you mean you've flashed a stock rom?

When I had this problem, the second/third thing I did was flashing the stock ROM. But it was with these problems too, and with some other weird things: the S Note and the Samsung Keyboard giving FC almost every second.

Well I guess if you're getting these issues when completely on stock I reckon you need the service centre?

Have you try formatting your internal sd? I got similar problem too when flashing 4.3 mj5 leak.
Also got a uid mismatch when the phone start. I format my internal sd then flashing 4.1.2 firmware back.
Not a problem after that.
