Hi all,

I have bought an old -C6603- (Update: It seems the mainboard is of LT36h 1267-1735.2?), but it does not detect Sim card. But if I insert the one of another Operator it works. For details:
- Device is running 5.1.1 (Arabic FTF). Had tried the CE1 but not work.
- My Operator is Viettel (Vietnam), I have renewed SIM (from Operator) with no luck.
- Sim from another operator (Mobifone - Vietnam) works.
- Disassambled device. The CDA is 1267-1735.2
If anyone knows the problem or has solution, please help me!
One more question: Is it related to Baseband?

Hello
This is my first Xperia device I just came from a lesser known android brand. I have successfully rooted my device 5.1.1 firmware 10.7.A.0.222 using Kingroot and verified by Root Checker. I would like to know what the next step is. I am having a little difficulty with the new jargons i've encounterd e.g. bootloader, flashtool, fastboot. I didn't encounter any of these in my previous device. With that I was able to flash custom roms and kernels instantly. i would like to unlock my new phone's full potential and I'm looking forward to learn from this community.thanks.

First you will need to check and see if your bootloader is unlockable, that can vary from model to model and whether it was ever carrier locked or not.if it cannot be unlocked that's going to limit your flashing ability

Using mobile data causes a lot of heating. Stick to wifi. Lemme know if this helps. You can also use another ROM.

Are you using any custom ROM? I am currently using Xperia_Z_Customized_Sony_5.1.1_by_androidexpert35 and it works great. I once played around with its CPU settings for a better performance and everytime I took my phone out of my pocket it was hot. So I had to change the settings again to stop the heating.

Too many background apps may also cause the heating. See Data Usage in the settings to check which apps use the internet the most. Try restricting the background data for those apps.

Lemme know if it fixed anything. :good:

A custom rom will allow a better control over your device. It has almost a 100% chance to fix this issue. If you go for a custom ROM then I recommend a stock based ROM as you get the Sony apps like its Camera and Music player etc.

Other suggestions are, try enabling "Queue Background data" in Power Management settings. I prefer not using apps like greenify and ram cleaners. Coz after the app gets hibernated or its memory in ram gets cleared, the app tries tp reload itself and in turn uses more processing power than you saved.
Xperia Z is a powerful phone with 2Gigs of RAM and its very unlikely to run out of memory.

Lemme know what you are gonna do next.

Ya. Tried it. Its good. have you unlocked your bootloader ?

 

[malik97]

no, is it necessary?

 

[hx4o5z]

no, is it necessary?

I suggest you do it. You are gonna loose all data so back them up. And it is safer, and its easy to change to any ROM easily.
