Phone not booting up, dark screen, fear of bricking! - Android Q&A, Help & Troubleshooting

Hello guys. I have this Amaway A725 Tablet which I have rooted a month before. I tried to change the boot animation, which was when my tablet started rebooting and stuck at boot screen. Then I managed to install device drivers for MTK 6572. Then I tried to boot into bootloader using adb reboot-bootloader. My tab switched off and now I cannot even switch it on. I fear that I would have bricked my tablet. Please help me.

I don't know the device, but I don't think you can brick a device just by changing the boot animation.
Can you reboot in recovery? If so, do a full wipe

A factory reset would not affect the boot animation in any way,shape, or form.
OP: You'll have to see if you can find the stock firmware somewhere. Unfortunately, with little to no documentation and not much incentive for manufacturers making cheap android stuff to bother with all that, it could be quite a task.

Yep I tried factory reset from the Android System Recovery, by pressing the Vol+ and Power Keys. But now I count switch it on by any means and key combinations and I cannot remove the battery because it is irremovable. But if I plug it into my PC Device Manager shows this device "MTK USB Port" connecting and disconnecting. So what do I do?

Found the firmware and downloading it from Amaway.cn website. But what do I do now, how shud I flash it, bcoz my tab wouldn't start up by any means, no recovery, no fastboot, not even showing the charging status. Please guyz I totally depend on u, help me !!!

Folks, tried using the MTk USB Port and Mtk Droid Tools, but how to get the firmware.info or pmt file for it?

BROM ERROR : S_BROM_CMD_STARTCMD_FAIL (2005)
[BROM] Can not pass bootrom start command! Possibly tartget power up too early.
[HINT]:
What do u mean by this???? I used SP Flash Tool v5.1348.00

so, its not bcoz of my device chip is damaged? ok then. thanks!
there is no way to know with that little information. it can be, of course
2) Half SDS as it has not-so-affectionately become known. This tends to be more of a boot loop of the Samsung boot splash. the eMMC is partially wiped out. You cannot boot into android or recovery. It fails at the boot screen, but the screen does turn on none-the-less. The only; thing you can do is top boot into Download mode.
actually this happening to my device now. any solution?
You don't know if this is what's happening.
Provide information. Provide the Odin log.
Type out what the download mode says.

Authorizing a device while stuck in boot loop

Hi,
I have a Galaxy Nexus with the volume buttons spoilt (not functioning). It is rooted and running on AOKP's 4.4 rom. I accidentally installed the wrong kernel and while panicking, I wiped the data and davlik cache. Now, I am stuck in boot loop. Also, when I plug it into the computer, the phone is UNAUTHORIZED according to adb server.
Is there any way to authorize my phone without booting into the OS itself?
or
Is there a way to boot into bootloader/recovery without authorizing the phone and without using the physical buttons of the phone?

Unfortunately given the circumstances you've presented, you'd appear to be stuck like that unless you can get those volume buttons working. Because you can't get to the boot loader and recovery or get the phone to boot and even worse, adb not functioning, you're stuck that way. Unless someone knows something i don't, it's just the way it is.

Has anyone solved it out? Got really similiar problem. Stuck in bootloop + hardpressed vol up. Vol Down should work properly tough, but have to admit that problems occured using VOL Down or even power beacause of hardpressed VOL UP. My device (Htc ONE S - s4) is fully rooted, unclocked, etc.)
Is it possible that Bootloader got broke somehow?

[Q] I-9300 bootloop and no recovery

Hello,
I have a S3 which is stuck in a bootloop at the samsung logo.
when i turn it on it shows the logo for some seconds then the screen goes black and the logo re-appears.
i can not boot into recovery mode, but download mode is working without a problem every time.
i tried flashing stock firmwares with odin and also tried kies emergency firmware recovery. the flashing always went without any problem, but it had effect. whatever i try, i am never able to boot into recovery and still stuck in the bootloop.
in some tries after flashing the screen just shows the samsung logo forever, but after rebooting it once it then is stuck in a bootloop again (shows the logo - screen goes black - shows the logo...)
i also tried flashing TWRP and CWM via odin, but again i can never boot into recovery mode.
what should i try next?
thx alot for any helpful comment

You can Try this:
1.) Pull out battery
2.) Put it in again
3.) Press Vol up + home + power
4.) When the Samsung Logo appears let it off
I think you press the Buttons too long.
I had the same problem!

i really tried everything, it's not working. btw with i am stuck at the very first image, where it says "samsung Galaxy sII GT-I9300".
i dont think it's just the way i press the buttons because i can reach it on my s1 and s2 without a problem, it's just not working on this device.
could some setting like "nand erase all" in odin help? in other threads there is sometimes mentioned that the internal file system might be screwed up and in those cases a simple odin reflash does not help anymore...
Nand erase will usually hard brick it. Try the rescue firmware from general forum, sticky thread. Follow the guide exactly as it includes a pit file.

thx, but i already did that (multiple times) and flashing via odin always succeeds. then the phone reboots and is stuck at the first samsung galaxy s.. screen. twice i managed somehow to get into recovery (after flashing cwm6) but it then randomly rebooted.
and i dont think that the power button is stuck because when i am in download mode it is perfectly fine it never reboots itself unexpectedly.
Had a similar issue on my tab2 p3100. It all happened when I tried flashing a custom recovery from rom manager.
A bad flash of anything related to recovery or bootloader could be a probable cause.
I remember a knowledge share on one of the threads describing this issue and as mentioned on it all I had to do is this:
1) switch off the device and plug in the charger. This would light up the display showing you the charging status. The status has to show if at least your bootloader part of the phone is fine.
2) plug out the charger and immediately press the three buttons (home + vol up + power) get into recovery mode. This step has to work and help you get to recovery mode.
***Note : the interval within which this step has to be performed is too short since the display would turn off immediately as soon as you plug out the charger. A bit tricky too so you have to be fast. If this misses getting you into recovery, pull out the battery and put it back again. Repeat step1 and 2 again.
3) upon successfully getting into recovery, perform wipe data, cache and select reboot phone from option available on recovery again.
Allow the device to boot. This could take a while since you have performed a data wipe and may prompt for first time set up.
I was able to restore functionality on my tab after these steps and like ppl learn from their mistakes, I then learnt that recoveries and bootloaders are things that needs to be done with a pc only.
Worth a try if you have tried other alternatives and found no go. may help. Who knows..
all the best.
thats also not working. i tried to get into recovery since two days now...
i also tried the steps from this thread: http://forum.xda-developers.com/galaxy-s3/help/solved-pit-bricked-dead-problem-gt-t2535367
but again, after i flash the cf-root (successfully) the phone does neither boot into recovery by itself nor can i do it by hand...
its crazy... in download mode i can see the model number (GT-I9300) and i thought as long as the model number is there and i can enter download mode there should be a way to recover the device.
but i cannot think of anything to try that i have not done yet
If the rescue firmware didn't help then it looks like the emmc chip is damaged.

is there a way to make certain of this? how can i tell if it is really a hardware damage and not just a software brick?
i just dont want to let the phone go, it looks still so shiny
is there anything else that could cause the phone not booting into recovery mode after flashing custom recoveries?

Same here, still didn't found how to fix it.. I guess our motherboard just died..
Howewer I have a solution that "almost" worked for me.
Get a stock firmware in odin and turn on Nand erase and T-flash
When it's done phone reboots and you'll see just "Downloading..." mode when you turn it on.
Then got to Kies and Select firmware recovery...
Enter s/n and model name and wait for the flash to complete.
With it , I got past boot logo and actually booted into android but the phone crashed because I guess I have a memory issue..
Well , gl. If you don't find anything else helpful , try going with this method..

I might have bricked my phone (XA Ultra Dual - F3216) - it gets stuck when booting...

I followed this guide:
https://forum.xda-developers.com/xperia-xa/how-to/f31xx-how-to-root-xperia-xa-noob-t3430170
With some specific files (boot and recovery images) from here:
https://forum.xda-developers.com/xa-ultra/how-to/how-to-root-xperia-xa-ultra-dual-t3439173
The rough steps that I took:
Put the UPDATE-SuperSU-v2.76-20160630161323.zip in the microsd
Unlocked the bootloader
"fastboot flash boot boot.img" and "fastboot flash recovery recovery.img"
Booted into TWRP
Since the internal data was shown as (0) , I Wiped the device.
Installed SuperSU-v2.76 from the microsd
Rebooted the device
It did an automatic reboot after going through the logos (I guess this part is expected after installing SuperSU)
After that, it gets stuck on the Xperia logo (the video logo keeps playing)
Now, after I turn on the device:
It goes through the Sony logo
It goes through the Android logo
It gets stuck on the Xperia logo (while playing the logo)
It doesn't get passed the Xperia logo.
Things I can still do:
I can boot into TWRP recovery (yay?)
I can use adb sideload with TWRP
I can't yet get back into fastbood mode, but I guess I can if I keep at it. I could go to fastbood mode before, but for some reason I can't anymore. I think it has to do with drivers. By default it recognizes the device as "SEMC flash drive" and will not recognize it as fastboot. After about a minute or so, it will disconnect the "SEMC flash drive" and boots the phone.
Give it to me straight, is my phone actually bricked?
If not, please let me know what I can do to fix it. It is very much appreciated to hear from anyone about this. Thank you all in advance.
If you need any additional info (logs, phone details, etc. etc.) feel free to ask me and I will happily comply.
If you can't get through the bootanimation, then yes that's kind of a soft brick. A solution would be to flash an official firmware from xperifirm (preferably .100 or .111 in order to to install root successfully) and then get everything done with simple baby steps. After flashing, you can wipe your data (if you wanna), reboot and then install root (I do not recommend flashing supersu and wiping at the same time when using an official firmware).
Note: Because we are stuck with only official fws, boot and recovery files can only work on specific fws

Hey
Thanks for your reply on my cry for help.
So basically get the firmware from Xpeifirm, make sure boot is working fine (basically back to square one ... sorta), then root by installing the SuperSU again. right?
I had already looked at Xperifirm before this. but I couldn't figure out how to properly use it. and now I'm a bit stuck.
I followed these:
https://forum.xda-developers.com/cr...xperifirm-xperia-firmware-downloader-t2834142
https://www.youtube.com/watch?v=X_Y-BOWlQdw
But when I follow the steps, I get stuck here (when creating the bundle using the bundler in flash tools) :
http://imgur.com/a/wl3Cc
Any ideas on how to proceed?
Also another question. Can I get away with using adb sideloader instead of flashtool? some driver problems that are bugging me ...
Appreciate your response and thank you so much!
sony- android- xperia- off
good day! i hope im on the correct thread. i am having this issue on my xperia xa ultra dual.
everytime i turn the device on, it displays the sony logo, then the android logo, the xperia logo, then it turns off. i cant seem to get past through this regardless if i'll press the volume- and power or the volume+ and power. im almost certain that this can be fixed by doing something on the flashtool. i guess i just dont know how to do it. a step-by-step tutorial is greatly appreciated.
Can you get it into fash mode? If you can just flash ftf file for your phone.

If you are under warranty send in for service their no known fix for this.

boot loop flare s play

anyone can help me? I've tried to root my cherry mobile flare s play, I've flash twrp on it but it always boot in recovery it doesn't boot in system partition so I tried wiping the cache and dalvik cache, still doesn't boot so I tried flashing another recovery/rom and it just get worst it's now stuck in boot loop I've already tried the abd reboot-bootloader and always fall in error: device not found., I hope someone notice my case. thanks
Hello, this happens when the system is actually corrupted
you may reflash stock then twrp then root again
or just get a custom recovery for your device
you must go in bootloader for stock rom or twrp for custom rom, and that's fine your phone just needs a rom and its good to go
good luck

Hello again, take out the bettery then put it back and use the bootloader combo
if it didnt work take out the bettery and flash through sp flash tool
nothing to worry about, i didnt notice that your phone can be flashed through sp flash, since it just requires the phone to be off
not really such a scary situation

in my case I can't flash even a recovery image using sp flash tool. any help? sorry if I look like an ignorant any way thanks for your help guys, I really appreciate
no no problem, however what's the problem ?
I'm trying to flash a custom recovery on it but it doesn't work, I'm trying to flash twrp, the one I've flash before, because I don't have the stock rom of my device so I'm doing the process partially. I'm aiming to flash twrp and then restore my saved back up.
Hello,
i think your device stock frimware is there on google, however when you try to flash what error does it give or what happens ?
It doesn't show any error message and not showing any progress at all. my device just blink showing that the battery is charging though the battery is not present.
if it didnt detect it try pressing the volume up or volume down to make sure while connected ( and download button is pressed
just blink until it reaches time out.
I'm sure that my cable is working, it works on other device. I already install all the drivers I need.
is there a way to stop my device from simultaneous booting? it appears to be detected on device manager but just for a few sec, then reboot and appear again.
ensure the ROM is loaded properly in the flash tool.
Switch off the phone and remove battery.
press the start button in the flash tool to initiate the ROM flashing process. The process will be in hold, waiting for the phone to accept the new firmware.
Now connect the phone to computer.
Try these. Press and hold VOLUME DOWN OR VOLUME UP OR POWER+VOLUME UP OR POWER+VOLUME DOWN. One of these should work and the flashing process should start.
can I obtain the stock rom from the same device? I have the same model and it works properly. I can't download the stock rom from mediafire it always fail due to poor internet connection so I'm looking for another way.
I tried updating my driver then my device was recognized but when I flash the recovery image it displays 100% but in red color.
