[Q] phone keeps restarting after root - Sony Xperia M

Hi,
I rooted my phone (xperia c2005, android 4.3) using iroot from pc. The sd card was removed.
The root was supposedly successful, I tested using Terminal Emulator, typed "su" and the # showed up.
After the root directly, the phone restarted couple of times by itself (it would reach the home screen then after around half a minute it restarts again). Then it stayed on and working fine. All the above happened without the sd card.
Then I switched off the phone then turned on again also without sd card, because I wanted to make sure it was working fine, but it also restarted like described above, reaching home screen then restarting.. Many times, like 4 or 5 times, then it stayed on and worked fine again. Now this is happening each time I turn off and on.
Not to mention when I tried putting back the sd card. I put it while the phone was on, and it worked just fine. Then turned off and on, and the phone kept restarting without even reaching the home screen, it would just reach the colorful dancing lines then restarts again and keeps restarting until I remove the card.
Please help. And could you please use simple instructions if possible because I'm very new at this
Thanks.

how do i know if i bricked my phone?

I was trying to flash the new version of EnergyROM and when i ran a task29 i accidently left my SIM card and SD card in. I loaded it to the bootloader screen and it was saying USB on the phone but my computer wasnt recognizing it so i went and bought a card reader and tried flashing from the SD card and now its stuck on a black screen with the red light in the corner always on. the phone wont turn on and the light only comes on when its plugged in. please please help me i just bought this phone 2-3 weeks ago and didnt get insurance.
Generally, if it is bricked, it won't turn on or just constantly reboot. You can access bootloader mode by hitting the down volume key while holding the soft reset button.

that what it seems to be doing, ive run task 29 twice and tried to reinstall the ROM that worked earlier today and it just loads up to the BRGD ATT world phone screen and acts like it wants to boot up and then just goes back to the black screen any ideas on why?

Recharge the battery using any External Charger (called universal charger)
Then, put battery back into your kaiser. Keep Camera Button pressed and insert USB Cable (remember you must have sim card and SD card removed). Then Disable USB in activesync and flash with default HTC rom
I was able to install the stock rom.
The phone only load up on one occasion with the following things are met:
sd card removed
connected to computer or charger
and hold onto reset button for 3 seconds
It won't load in any other way.
THe next thing I did was to install an android kernel.
I was able to get into linux with the above items are met.
In the linux screen, I try install the SD card in while it was "waiting for a SD card" <- not sure if I should be even doing this, the phone will immediately shut off.
Could this mean my SD card became faulty? Window is still able to read it via a card reader.
Any help would be appreciated.

[Q] Tried to root phone failed now SD and debugging don't work

I tried to root my phone but on the last step it said the internal memory ran out.
I Restarted the phone and it kept restarting at the boot screen. so I went to recovery mode and used a recovery file name (Esprimg.zip). After that My phone would only start if there was (A) no SD card when starting. or (B)the phone was connected to the computer but after I unplugged it from the computer it would reboot. Now with the phone on it will not pull up the SD card it does not even see it in normal operation but it does see it in boot mode(volume down + power).Also debugger mode will not work on my phone the box is checked but no icon appears at the top and when plugged into my computer it won't recognize the device.
Please help me even if just to get it to normal operation I've already done a hard factory reset.
76 reviews and I have not even got an idea I guess I'm alone on this problem.
I don't know lol, all I got was, have you tried a differend sd card or formatting the one you have? I am not sure what the essential things you need in there, but I would try to remove things till you only had the essentials. Back it up first of course.

[Q] N7105 turned off for no reason & wont turn on

Hey all,
Having a problem with my N7105 (international), in that it suddenly turned off for no reason at all and will not turn on at all. No red led, not sound, no display light or anything. Simply off and wont turn on.
I was web browsing and playing a game (stunt star) 20 mins prior to placing it into my pocket and walked outside to do something. Wanted to check the weather when I noticed that the phone was off.
Tried turning it back on with no success. Even tried download/recovery mode and still wouldn't turn on.
Tried placing it on charge for 15mins (no red led came on or battery display indicator) and turning it back on, no success. Tried a spare battery I had and that didn't work either.
Even tried a usb jig I had lying around and that had no effect.
The phone had been running on 4.1.2 ZHDMB1 (hashcheck hybrid v2.2 with Perseus Kernel 33alpha, so I can't see why it would be the SDS problem) with philz touch 5.06.1 CWM.
I had checked if it had the emmc bug issue with that emmc checker on the play store, and my device came up clean with no detectable problem.
I did notice triangleaway popping up tiny messages stating that it had been granted shell interactive access (something like that) during the game I was playing, but i figure that was related to it requesting root access from SuperSU; which it had done numerous times before with no issues
I did do a nandroid backup a few weeks ago so I do have most of the stuff backed up on the micro SD card, but there are a few files that remained on the phone that I would like to recover.
Even if the phone isn't recoverable, is there anyway for me to access that information with the phone still off?
Not sure why this is happening, but any advice/suggestion on how to resolve this would be much appreciated.
I would suggest you to remove SD card first and then try to boot it up without it.
If it's won't boot up even without SD card, and can't go into download or recovery mode, it's means that you have SDS issue.

Thanks for the suggestion.
Tried it without the micro sd card, still won't boot up or go into recovery/download mode.
From what I've read (briefly), most SDS cases involve the phone still emitting a red led when connected to the charger (I could be wrong).
Whereas my N7105 LED doesn't light up red at all; what's the likelihood that its something to do with the powerboard circuitry instead?

OPPO Keyboard has stopped working, leading me to stuck on a fastboot loop.

Please help. This is a serious matter for me.
Started having this problem at February 14th, 02.10 AM.
Have been looking for the answers in the Oppo Forums too but still got no answers.
Okay, I have a habit, which is moving all of my applications from my internal storage to my external SD card, after I let those applications doing their functions and programs and features and so on for a while. It's not a big deal for me to set up my phone again after I restarted it, and usually it works perfectly. Just restart and I would get to operate my phone again. However, this time, I got a bad luck. The worst one, considering the fact that I'm all-around-gadget.
Here's the results I got from reading a lot of threads (not only from this forum and OPPO forums):
OPPO Swype Keyboard has stopped working? Really?
After restarting my un-rooted Find 7 (9076), I cannot type the password on my lock screen. Like any other Android devices, it would always come back to it's system or default applications, I knew that fact. But this time, when I touched the blank space to type my password, nothing came out. No OPPO Keyboard, which happened to be OPPO's default keyboard. No other keyboards. None at all.
So, I cannot do one single thing to my phone except just turn it on and stared at it like a complete idiot.
Then I decided to turn my phone off and turn it on again after a while.
But still, the same thing happened. No keyboards.
That time, I decided to turn off my phone again and pulled out the battery and my external SD card.
After putting the battery back (External SD Card was still outside), and turned it on again, the same thing still happened.
Sliding my fingers up and down, nothing happened. The touchscreen was still there, showing me my date and time even though I was sliding my fingertips up and down.
Not too long after, I felt my phone got warmer and warmer. I tried double-clicking the home button, which I already set to unlock the lock screen, was also useless. The screen was still black and locked. When it got over-heating, automatically I pulled out the battery without even turning off the phone.
That one was my fault. I knew, and well, honestly speaking, this is the first time I'm in this kind of situation. In the past, my Find 7 would just suddenly restarted itself then everything went back to normal, but not this time.
And here's the beginning of my Fastboot Loop.
Fastboot Loop on un-rooted device
After pressing the Power button and the Volume Up button at the same time, it would bring you to the Recovery Mode. When I did that to my Find 7, it brought me to a black backgrounded screen with cute OPPO mascot and some Hanzi (Chinese handwritings). Picture attached.
I tried to wait for 2-3 hours and found nothing happened.
Pulling the batter out and putting the batter back would do the same.
In other words, I am not able to gain access to my Recovery Mode.
Why didn't bring the phone to the service centre?
I thought about this already.
When I tried to connect my phone to my pc, it can detect the phone but cannot access the files because the phone was still locked with the password.
Usually, the service centre requires us to unlock the phone if there's a problem with it, right? In my cases, yes.
I was searching all night to find out the answers.
I found some threads about the Fastboot Loop thing and etc, but they are only for rooted devices.
I'm using:
OPPO Find 7 (9076)
Color OS 2.0.5i Beta
Android KitKat 4.4.2
Device is not rooted, still original.
Still dealing with the same problem until now (the time I post this thread).
Anyone has solved this problem and guide me step by step to finish this?

boot into recovery and format the phone, this should fix it. If you want to backup your data, just boot into fastboot, connect phone to pc, run fastboot command from sdk tool, push custom recovery, flash twrp, make nandroid backup, fomat phone along with all the storage and then flash oppo stock rom (you need to download) or any other custom rom with gapps. To restore use nandroid manager, do not restore system files if you are flashing custom rom.

Thank you for your help Sir.
But, my Find 7 already operated normally again since I left it for a few days uncharged and off.
Then I got into Recovery Mode by pressing Power button and Volume Down button (not Volume Up button) while in the middle of my fast-boot loop.
It worked. I could gain access to ColorOS Recovery Mode.
So, I reset my Find 7, then re-installed my applications and everything again.
Thank you for answering!
