Camera and Charging Problem

X8 running MiniCM7 2.1.9 with nAa kernal-11
Camera
First access to camera since boot, it shows blank with camera framework there.
If i exit and return back to camera, the screen is now complete blank without camera framework. There saw once i got "Could not conect to camera" error.
Charging
Charge when phone is turned off, screen appreads with battery charging image. If i press on/off button to boot up rom, it stops charging(shown in settings>about phone>phonestatus) but my LED notification shows constant red.
Battery icon shows 0%
Sometimes after boot up it discharge at 18% and after sometime(i dont know how long or maybe it keeps on repeating) the phone restarts. and turn to 0%
Could it be virus? Cause my SDcard folders' name start to change to weird symbols.
Or because i dropped my phone on the floor?

Have you ever try to full wipe your phone?
Try to reinstalling your ROM, maybe it will help

Forgot to mention, i reinstalled 5-6 times the rom.
But havent data wipe.
Will the data cause these issues??

After i fix my sdcard, now the phone can be charged, but camera still dont work.

Do u have any partitions on ur SD card?that MIGHT have caused the camera issue.

no, 1 partition, FAT32, i didnt do anything to partition before this problem.
And now again the charging problem came, after i reinstall the rom.

Dont forget u need to factory reset after installing,it will only remove the stuff on ur phone not the memory card,anyway u can install em back
EDIT:Wait if i remember correctly,i used to use minicm7.2.x and after u install the kernel and rom u ALSO need to install gapps.zip files by flashing them with CWM,u better double check with the guys over at minicm thread .used to have charging problems cuz i forgot to install gapps.zip as adviced by them.
EDIT2:Yup u need to install gapps (google apps) there is a link there for you to download it,all u need to do is follow all the instruction given and it will be fine.

did you try to revert back to Stock ROM and Kernel?
if the problems gone, i think that's not a hardware problem..
do you have somekind like travel charger? you can charge your battery if your phone won't charge..

did you try different charger? maybe the problem is in your charger,

Listen here,its IMPORTANT to install gapps if u havent alrdy.
Step 1 flash kernel
Step 2 reboot to CWM then factory reset (full wipe) MAKE SURE U DO THIS.
Step 3 install rom minicm7.2.1.x and then gapps
Step 4 reboot,takes 2 ~ minutes
GAPPS is a VITAL Step it has nothing to do with ur charger nor hardware.
Edit:i know i might not be an x8 user anymore,but i had that problem because i didnt read the instructions propely.
Edit2: im using a apple wall charger and it works fine,charging my Xperia Neo V.

maybe, but first time i unlock bootloader, and use minicm7, no problem at all.
and there's some problem with battery now. Overnight 100% will become 0 %
I think its because malfunctioning camera keep running background, let me try to freeze it and see the result.

or, you can try to reinstall your custom ROM, and then full wipe data.
don't install any application except the preinstalled application built-in with ROM.

Im on ics rom right now and im stuck on it. My computer wont recognize my phone, i tried installing drivers and many other things but it just wont work... Can someone tell me what to do???

Did you try a other computer? Sometimes the computer fails to identify you device, happend to me 1 time.
Or try Blazr rom, fast stable and very long battery life!
Just put the zip file on your sdcard and copy it to your phone (since your computer doesnt let you connect via usb)
Then go into recovery mode en update via zip file.
See this link for the rom: http://forum.xda-developers.com/showthread.php?t=1628639

yep, the cable is likely the common cause and problem but not all cables are compatible, best to get original or bring phone and test data mode before buying as charging mode works on all
on the other hand, just examine your usb slot too..a slight misalignment can also cause this problem

[q] hard brick after downgrading to cm7.x again after cm9.x

so after a new update to the cm9 i found my phone a bit slow, so i decided to downgraded it to the latest cm7 version with the matching alf kernel. after the downgrade i found my phone acting very strangely.
after turning it on, the kernel and cm logo goes on, then it turns itself off, then again, again and again until the battery drains. i cant even go into recovery mode, so i cannot use my phone obviously.
can you help me with some advice?

Connect your phone is flashing mode by:
1. Keep ur mobile connected to the pc all the times.
2. Remove the back cover and the battery.
3. Wait for 10-15 seconds.
4. Press and HOLD the back button while putting the battery back in.
5. Launch PCC.
If this didnt work out, try to shortcircuit ur phone(it wont damage the hardware) by a dc charger.

Flash naa ics kernel back, then go to recovery and format data and system then you flash alfs kernel

not going to recovery in alfs &nAa kernel is "IMPOSSIBLE"
Both kernels include recovery so it should go to recovery .......
Reflash kernel / then full wipe {(important)+dalvik & system wipe}
U must always wipe when u upgrade or downgrade form ics/jb (cause whole system is different)

this is what the OP said.....if the phone reboots even before entering recovery then he cannot recovery...
and under some circumstances phone wont enter recovery... one is to be on ics on oxydo kernel and then flash back alfs with the ics rom... try entering recovery.. it will reboot.

[Q] Xperia V battery + bootloop problem

Hi, i got a really serious problem. I unlocked and put a custom rom (avatar) on my brand new Xperia V. Everyting was fine then i decided, that i need to root it too, so i followed a page wich i cant find unfortunately, and the result was a bootloop. I didnt really care about it, i decided to solve it later, but it drained all the battery during that time, and i used flashtool to put another kernel (Xperia.V.TWRP.Kernel.9.0.1.D.0.10.elf). Now when i put my phone without the battery it tryes to turn on every 15 sec (i see the boot screen), if i put battery in it shows its out of juice then after a few minits the led turns instantly green, and the phone turns itself on, and it runs out of battery in less than 20 sec and this repeats. Please help i really dont know what to do :crying: (might have time in fastboot mode to flash some things but i dont know really what i should do)

Can't you go full stock via flashtool?

i dont know how to do that i tryed to do that before the TWRP kernel, but it was not the sctock i guesss coz it had a bootloop (i really dont know im a noob ), i put the TWRP so i can install stuff from sd card. I really have to be fast before it turns off, so if u know a guide that tells exactly how to do that, i ll give it a try, but i didnt find anything like that unfortunately , and i dont really trust this random guides anymore...

I fixed my xperia several times through flashtool...its very easy actually....
1.download flashtool if u don't already have it.
2 download stock .tft file (stock rom wtv version) // // // // (of course for your device)
3.press bolt icon-flashmode.
4.pick the .tft file u put in flashtool's firmware folder where iu installed..
5.wait to prepare everything and give u plug usb screen.
6.while connecting the usb to pc press and hold the flashmode button on device (arc s-back key,xperia s -vol down) so check for ur device which key.
7.wait until it finishes then u can unplug and reboot.
Photos-vids-music dont get erased, other yes, and ull have a stock phone like u first bought.(includes kernel change to stock)

firt the red led shows, that the battery is empty, then it is charging (still red) then after like 1-2 min it turns green, and the phone turns itself on, tryes to boot, but battery gets empty (i dont know if it does really the led is just red again), and the phone turns off (the time is getting shorter i think btw), the main question if this cannot be fixed is, that i caused this by installink some custom rom or kernel, or the battery really is dead (wich would be really wierd since the phone is only 3 days old), in that case should i try relock it and bring it back to the store?

Then again this process continues. it is not going into recovery mode, flash mode , fastboot mode.
so if you can help me in this situation. pleeassssse

Sounds like a pretty bad bootloop does your PC recognise anything when you connect it? You need to go back to stock or at least to a working ROM. The long and short of it is to fix it you are going to need adb, recovery (if you have a nandroid backup) or flash mode. If you can't get any of them I think its bricked

Any idea how much charge is in the phone? I think you will have to keep trying to get into fastboot or recovery try power and then vol up/down or camera depending on what your recovery is I can send you a full nandroid backup of stock if you need one. You need to break into the boot cycle get into recovery (i am assuming you have installed a recovery on this device) timing will probably have a lot to do with it.
Programming is a race between engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.

make sure to use the stock sony usb cable as i think flashmode doesnt work well with other usb cables. also try the other usb ports on your computer. technically,you should still be able to enter flashmode and recovery.
