[Xperia SP Q&A, Help & Troubleshooting] sandy7:
Q1: I get bootloop after installing a custom rom. What is the problem?

A:

Have you done everything correctly?

-Firstly post your problem in the ROM thread as the devs there may help you better.

-Check your mobile compatibility with the ROM

-Check if you have installed the correct kernel for your ROM.

-Check whether you have done the correct wipes as mentioned in the ROM thread.

-Some ROMs require formatting system. So if it is mentioned in main ROM thread then you must do it.

-Some releases may require stock rom first before flashing the custom rom. So flash the stock rom and then the custom rom over it.

If nothing works just download the stock ROM for your mobile and flash it using flashtool. This may solve your problem.

Q2: Can you suggest me the best ROM or kernel or something like that for my smartphone cause i'm really lazy to do a bit of searching...?

A:

as per XDA rules a user is not supposed to ask for Best rom, one can go to dev forum and try some roms and decided which is best for them

Q3: I have rooted my phone successfully, now how can I install CWM (ClockWorkMod) Recovery?

A:

go here download the the cwm and follow the thread properly to flash there

Q4: I have a problem with this ROM and what should I....

A:

It's a ROM specific question, better post it in the ROM thread. They will help you better.

Q5: What is the safest way to root my phone or unlock its bootloader?

A:

Q10: How do I OC(OverClock) or UC(UnderClock) my phone?

A:

If your kernel supports the function and if your ROM has inbuilt option for the fuction then you can do it directly from ROM or else you can buy/download apps like SetCPU for your phone and can use it easily to OC, UC or change governer of your CPU. *Playing with your CPU is at your own risk and if you go anywhere wrong your phone might not be able to recover(permanent brick). So if you are a newbie(noob) just stay away from these things*

Q11: How does Thanks Meter affect my profile?

A:

Thanks Meter actually is not useful in becoming Recognized Contributor/Themer/Developer. It is actually the appreciation you get on you works. Thanks Meter has been made so that members of XDA stop posting just THANKS on threads and thread could be clean and helpful.

Q12: How to be a Recognized Contributor/Themer/Developer?

A:

Recognized Contributor is a role intended for members who produce some of the best original and helpful guides for users, as well as helping other users who have problems, in a friendly manner. Recognized Contributors will get a custom user title and the faster ad-free XDA template, as well as access to developer tools currently being created. Any Senior Moderator on XDA can add Recognized Contributors, should you feel deserving of this title.

Recognized Themers are those users who work (often tirelessly) on designing new theme graphics and user interface overhauls for ROMs. Users who aspire to be Recognized Themers should be creating original graphics work for their themes being released, demonstrate a commitment to crediting other users’ work when applicable, and seek the relevant permission in advance from the original creator. Recognized Themers will receive a custom user title and the faster ad-free XDA template, as well as access to developer tools currently being created. Any Senior Moderator on XDA can add Recognized Themers, should you feel deserving of this title.

Recognized Developer, as the name suggest are those who develop really good ROMs, kernels, etc. Anyone who is skillful and publishes his own creation other that just copying and pasting can be termed as recognized developer.

Q13: Why does my phone say Bootloader Unlock Allowed: No?

A:

It's most probably a simlock. The mobile you bought has a simlock of the particular company whose SIM is being used. Normally the companies used to provide the unlocking code after sometime but now I think it won't be provided from now since simlock unlocking has become illegal. But you can break your simlock through WotanServer, Omnius or some local shops.

Q14: Can you tell me how does thanks meter increases with regard to number of thanks?

There is a bug with meter it doesn;t shows 5 bars. Anyways the thanks meter doesn't judge anyone or status of any member. It's the works, his contributions and help he does.

Q15: What are BB Codes and what BB Codes can I use in my thread?

A:

Mainly every kind of text formatting that we do in XDA thread is governed by BB codes. Here is the list of all the BB Codes we can use in XDA and explanation of each code.

Q16: Is there anyway to mount my sd-card using CWM recovery?

A:

Yes! Many versions of CWM support mounting sd-card through it. For that go to Mounts and Storage->Mount sd-card and you're done! But remember if you press back button then your sd-card will unmount instantly.
