[AT&T Samsung Galaxy S II Skyrocket SGH-I727] bloodcurdler:
Hi,

First I want to say that although I am not a total newbie, I can be considered as a newbie. I have windows 7 32 bit. I am starting from the beginning.

Until about 1.5 years ago, I was used to connect my phone to Kies and do a "firmware upgrade and initialisation" after feeling that it is time to do so in order to speed up the phone back. Does it speed up the phone back? I'm not sure, but as a guy that still formats his pc from time to time maybe it's a habit.

But about 1.5 years ago when Kies told me that my phone is not supported any more I couldn't do that. Then I made some search and found out cm.

I first installed cwm 6.0.4.3 to my phone by heimdall 1.4.0 then installed cm 10.2.0 and gapps-jb-20130813. I thought it would be good and my phone would be faster since I wouldn't have the unnecessary att apps. It also supported Turkish whereas the stock only supports English and Spanish.

I actually liked it at first except for some parts. Then a few months later the phone switched its language to English itself and started to behave abnormally, so I switched back to latest att stock rom by using odin3-v1.85.

Then about 3 months ago my phone got some water inside when I was under the rain with my phone in my pocket and my pocket not being sealed enough. The phone at first said please insert sim card when it was actually inserted, then I noticed it got wet. I immediately turned it off and removed the battery. Then opened it up and let it dry for a few days.

The phone got back to normal except for a single issue. When I charge the battery the screen behaves abnormally. The abnormality increases with time during the charging, I thought it is related with the phone getting warmer during charging. After the phone turns the screen off after timeout, It does not always turn it on after I press the power button. It starts at first by turning on after a few trials up to not being able to turn on during the charging process. When I unplug the charging cable, I can turn the screen on after a few trials. The phone gets back to nearly normal after 10-15 minutes. Although the screen does not turn on it still responds, for example I can answer a call. And sometimes the screen turns on with being upside down and flickering but responding as if its not upside down.

I hope I could describe the problem well. So this may be a hardware or hopefully a software problem. So I decided to first go back to factory settings. The problem with the screen continued. Then I installed the stock rom by odin. The problem continued but I noticed that the two applications I installed after resetting to factory settings remained in the phone. odin either not installs the rom or installs it by copying files, not formatting the system partition. I thought maybe formatting and reinstalling stock would solve the problem with the screen.

I made some research and noticed that I could actually increase the system partition, which is awesome since I always encounter filled memory problem when I try to install an app so I uninstall some apps to install the new ones. If I manage to repartition the system drive, it also has to format it.

Then I installed the stock rom using the pit file someone uploaded (6GB system partition), I did it but got an error from cwm upon first boot saying something like "unable to mount F", when I ignored the error the phone seemed to turn on but got stuck with att sign. When I pull the battery and turn it back on the phone got stuck at the same place without an error from cwm. Then I installed the stock rom with the original pit file, now the phone turns on but I still have previous apps. I repeated thes a few times (6gb pit file, original pit file) but nothing changed.

Then cm came to my mind, it would format the system drive. I repeated the same procedure I did 1.5 years ago. The phone turned on. I noticed that the internal sd drive had the previous folders,so I wiped the sd drive with cm. Everything was fine but the problem with the screen continued which stated that the it was a hardware problem. There was no reason to stay with cm so I installed the stock rom.

The phone asked a password from me since it had encrypted folders :( ???. I didn't provide a password, I think it did not recognise the sd drive wiped by cm.

I couldn't install cwm 6.0.4.3 with heimdall, it gave an error at the end. I decided to install a recovery with odin so I installed twrp 2.8.7.0.

I installed cm with 6gb pit, with original pit, installed stock rom with 6gb pit, with original pit with random order and how many times I don't remember that I brought the phone to a state that it won't boot. It turned on with odin mode though. Even the twrp did not recognise the drives. So I wiped all with ext4 format.

Now I have cm with 6 gb system but I want to go back to stock rom. cm drains up my battery. I also noticed that I really got used to the stock rom. I would appreciate it if I have 6 gb system like now. But if I have to reduce it back to 2 gb I don't care.

Can someone please help me?

Sorry for the long post, I wanted to state the problem as good as possible.
