ORIGINAL POST :
Hi everyone, I have an issue preventing me from making a tablet work.
Let me guide you through what I have done and can do :
- Acer Iconia Tab 10 (A3-A40) runnig Android 6.0
Problem :
I cannot boot TWRL through fastboot (fastboot boot recovery.img) because it gives me an error (low power - need battery charging). But there is no other way to get the tablet back .
Plus, I cannot charge it while pwered off as I get the following message (along with a battery charging icon) :
Orange State - Your device has been unlocked and can't be trusted - Your device will boot in 5 seconds .
This prevents off-mode-charging as it boots up the tablets after 5 seconds.
How did that happen :
Unlocked the bootloader, booted the tablet, had to use Magisk 13.0 modified by someone to work on the tablet (SU doesn't work.) and set the tablet up.
I then had a popup for Magisk having an update (to 16.0). Accepted it, which resulted in a bootloop.
Wanted to reflash the stock ROM and root it again, but it was 4am and people were sleeping, so I decided to do it the next day. Unfortunately, the battery died while I was asleep.
I can't run some commands in fastboot because it gives me an error : (not support on security).
What I have tried :
Charging the tablet in the (stock) recovery.
Charging the tavlet in Fastboot mode.
Charging the tablet while letting it bootloop.
fastboot getvar all doesnt give me any battery info.
I have all the files I need to make the tablet work (Stock ROM, root files, TWRP file...). I just can't get to flash anything, and the battery doesn't charge.
I just need either :
- A way to remove Magisk from stock recovery
- A way to bypass the fastboot (low power - need battery charging) error
- A way to charge the battery
- Or any suggestion you have
The fact that there is next to nothing about the tablet on the internet is very unfortunate and makes it harder to troubleshoot.
Thanks in advance for your help.
Did you try charging from a wall outlet, while the device is powered off?

Yes. But everytime I do that, the device has a message stating "Orange State - Your device has been unlocked and cannot be trusted. Your device will boot up in 5 second".
I believe this prevents off-mode-charging by forcing booting up my tablet.
Strangly enough, fastboot tells me off-mode-charging is on, as of the following :
fastboot getvar all
(bootloader) off-mode-charging 1

Try charging if the phone automatically turns on, keep charging, then hold down the power button until it shuts down.
If it still reboots, try adb reboot bootloader, then choose power off. That should do the trick.

It reboots before I can power it off manually with the power button.
And I cannot access adb as I only have access to the stock recovery and fastboot.
Plus, I can already choose "power off" in the stock recovery, and it stills boots up when plugged in.

So my friend picked up a broken Z Ultra for god knows why, and he's asking me to fix it.
I first test the device by connecting it to the charger, it boots. Alright. But it won't pass through the battery screen. Upon holding the power button the device vibrates 3 times, screen goes black and restart again as if the device was forcefully shutdown just like any other Xperia devices.
I connected the device to a computer, it went straight into fastboot mode. I thought, "Alright, this device should be locked, let's unlock it." Nope, it was unlocked, the fastboot responded with FAILED: "the device has already been rooted." So I booted the device into flash mode, and flashed the C6802 14.4.A.0.108 FTF. The flash process went fine.
After rebooted, again, same issue. It doesn't pass through the charging screen, if I hold the power button it'd just shutdown. Where do I go from here?
And yes, I can't access recovery mode either it seems.
Try and flash a cm/etc boot.img to the device and then flash the same ROM the boot.image came from
Good Evening,
I have a Padfone 2 wwe running stock firmware and locked boot. Yesterday the phone just stopped charging and wont turn on normally. This is what happens:
When turning the phone on: Shows the empty battery icon and then immediatly reboots. This leads to an infinite loop. I've had it going through this loop for hours, no help.
When put the phone in the dock nothing happens. If I try to turn on the phone while in the dock the white spinning circles, usually shown when docking the phone, is shown for a few seconds then it turns off again.
When unplugged from power source I cant access neither recovery mode(power+vol down) or CSC/fastboot mode (power+vol up).
When plugged in to power source I get into CSC/fastboot mode. If I connect the phone to a computer I get a ASUS Fastboot loader devide. However ADB don't find the device when I use the ADB devices command. (Tried following the Tutorial: Un-Bricking Padfone 2 (and possibly other android devices): http://forum.xda-developers.com/showthread.php?t=2256977&page=4 guide)
When plugged in to power source I get to the first menu in recover mode (Recovery/Restart). However if I select Recovery the phone dies and the reboots again.
I've tried unplugging the battery for 30 seconds and then plugging it back in again, no help.
So my question is if you think a new battery will solve it or if I should try something else?
Thank you all!
Hey guys,
I had purchased this phone awhile back in 2012 and The model is: XT912. I had rooted it and installed a Custom Rom (Black Widow). The reason why I stopped using it was because I had a cracked screen so I upgraded to a different phone but having alot of issues with my new phone. So I decided to replace my screen for my Droid Razr, but its been awhile since i've used it and been experiencing issues of my phone not booting up and looked online for multiple solutions but no luck.
Issues are:
- Phone needs a USB Wall Charger to be able to be turned on, battery is charged fully but when I unplug my USB Charger, my phone turns off. When I try to attempt to do a fastboot session, I connect my Stock Motorola USB Cable to my PC and on my phone, it shows a white light. But when plugged in to a wall charger, my phone boots up but doesn't boot anywhere besides the motorola logo.
- My phone boots up, shows the motorola logo and goes straight to battery charge and it shows 0% then 5% then 100% sits there for about 3 minutes and then reboots.
- When trying to go into recovery, it stays on the motorola and i've left it there for 24 hours abd no luck.
I've tried multiple things, but its been very aggravating since I've been trying to look up solutions for the past week but still had no luck.
Please help =(

The white light means that your battery is empty,try this:
Booting from AP fastboot to charging mode
If the Device will only boot to AP Fastboot and it says Battery Low
Connect the phone/Device ato a Wall Charger (not PC)
-In AP Fastboot Mode hold Volume down& power buttons at the same time for +10 seconds
- When screen goes black...release power button
-Then IMMEDIATELY press and hold Vol - and Vol+ to boot to Boot Menu.
- In Boot Menu scroll down with volume down to BP Tools, press volume up to select
- Device should boot to Charging Mode with battery icon
- Once battery is charged, try flashing in AP Fastboot again
This will only work if battery charging Firmware is still present and not corrupted
If Motorola Device will not boot to Charging Mode, a Fastboot cable will be needed.
You can buy it or you can make one by yourself,look at the picture.
If you can boot to AP Fastboot mode use this utility to flash stock rom,here http://forum.xda-developers.com/droid-razr/development/droid-razr-utility-xt913-jellybean-t2861798
If nothing works maybe your battery needs replacement...

I've tried the troubleshooting steps mentioned above but no luck.
What I remember is that, back in the day when I installed the ROM, I wiped everything, incl. the Recovery partition and I believe android version it was on was ICS. When I installed Black Widow, everytime i would reboot it, i had to turn it on a certain way, sort of like safe mode. I've tried it though but no luck
Also, everytime I do plug in a charger, It does show a charge of 100% but once I unplug the USB, it turns off and the only way to turn it back on is plugging the USB back in.
I've also created the cable you've mentioned, but it still shows a white light when plugged into a PC. I've already replaced the battery and the battery is brand new. Just replaced it yesterday.
Any other suggestions? Is there a way to fastboot it so i can install a stock rom with the OTA?
Thanks.

You can't charge the phone with the fastboot cable,it is for flashing the stock rom with RSD Lite when your battery is low.
Here is everything you need
http://forum.xda-developers.com/showthread.php?t=3023837
Download Motorola drivers,RSD Lite,appropriate sbf file for your region and flash it.
Oh,use Windows 7,not Windows 8
Edit:
Use this utility because you have XT912

Ok, So I was able to get to the Boot Logo usuing HW Diag. and Boot AP and my screen would show safe mode activated, then it would boot up a logo and I believe its cyanogen mod. It has a Blue Droid with a ring circling around it, but then it restarts. Maybe if i'm able to boot it into safe mode from the beginning, i could start it up.

Power the Device Up in Safe Mode - DROID RAZR / RAZR MAXX by MOTOROLA
my z5 Compact is taking forever to charge and even after I leave it in for hours, it still says it needs to be charged. When I unplug the phone from the charger and try to turn it on, I get 3 red lights. Holding volume up and turning it on only gives me 3 vibrations. Before this happened, I used the phone all the way till the battery shut down. After that, I can't get it to charge any more.
Sounds like you over-discharged the battery. You should always avoid using the phone to the point where it force shutdowns due to 0% remaining battery.
Try hard shutdown by pushing and holding the yellow OFF button in the flap for 10 seconds, then charge the phone for about an hour and try turning it on.
If that doesn't work, press and hold ALL physical buttons simultaneously (VOL UP, VOL DOWN, POWER, CAMERA) AND press and hold the yellow button for 10 seconds.
The phone should vibrate or something, I forgot, then charge the phone for about an hour and try turning it on.
Volume up + Power for hard shutdown.
Can you get into flash mode or fastboot mode?
Plugging the phone into your computer and entering fastboot mode helped me once:
So you disconnect your phone, do a hard shutdown to make sure it is off. Press and hold vol up and connect it to your computer. If a blue light shows up, at least the basic circuits and bootloader are ok
Keep your phone connected for 30 minutes and you should (well, might) have some charge again.
If you can get into fastboot or flash mode but still can't boot up, try reflashing your phone (if possible), esp. your boot partition.
try charge with QC2.0, adapter will charge device on 9v, its standar QC2.0, when your phone drain of battery until shut down, down turn it on. Your phone must connect to charger and wait untill 2%-4% of battery before turn on.
if charger fail, change your battery, dont force charge before IC power broken (dead)

I am running on a 5823 imported from the UK (i think). Is it safe to flash boot.img prescribed for the 5803.
Also, where can I find a collection of boot.img for the 5823? I am not really sure I am doing this right.
Re-writing boot in fastboot mode will only work if your device is unlocked, and although unlocking should happen in the bootloader it is not something I would risk with an already bricked phone. Maybe as a last resort thing.
But IIRC just keeping the phone connected to your PC in fastboot or flash mode somehow bypasses some of the charging logic*, so just leaving your phone to idle might give you some basic battery charge to start with.
If you can enter those modes: You can re-flash your phone with stock firmware using the proprietary flash mode (Vol-Down when connecting to PC, green led should show up). Search for 'Xperia Flashtool' and/or 'XperiFirm', there should be lots of information, these tools help you download Sony firmware, too. I would not flash an image for a different phone type, I guess there is a reason why they made 2 firmwares
If you still only want to flash boot.img (= only the 'boot' partition on the flash as a raw image), you'll need an unlocked bootloader first. Also, if you already have an unlocked bootloader, you probably have installed a custom ROM (why else do you unlock your bl?). To avoid any more confusing error sources, I recommend flashing exactly the boot.img via fastboot that came with your custom ROM and that worked until now.
*Most likely bc there is no kernel to optimize (read: mess up) charging. I once had a Z5C with more-or-less blown charging 'stuff' and I was able to charge it in fastboot mode as a workaround.
Three red blinks is, afaik, a status message for a dead battery. It has been discharged below safety limits, and is no longer safe to charge.
Hello friends, I come to report here a problem I'm having with my device.
It is not charging my battery, I thought it was a problem in the battery itself, I made the replacement for an original, but the problem was not solved. the device uses all the battery power, it stays at 0% and it does not charge, besides, it recognizes my SIM card, but there is no signal from the operator to make calls or use the 4G network, I did a lot of research I saw that it was a problem related to Software, regarding the CQA test, I saw several tutorials, where none succeeded, lastly, I would like to install a custom rom to see if the problem would be solved, but I went to do the bootloader unlock process, but when Fastboot displays the code and I enter the site of the motorola, it returns me with an error that I can not unlock the bootloader of my cell phone, and I need to unlock to be able to customize the android.
follows a video showing what is happening with my device.
https://www.youtube.com/watch?v=17roum_XlzQ
sorry if my text contains errors, I'm from Brazil and I used the translator to write
Thank you if anyone can help me because I have the device stopped because of this.
Thank you!
Hi, had the same issue. What helped me was connecting
power cable, going to bootloader, from there navigate to recovery. When it boots to recovery, regardless if there is any, leave it for some time. After about 5-10 minutes try rebooting, and it might picked up some charge, then it should charge as normally but very slowly, cellular connection also appeared.
Last time when my phone went to 0% and after going through this procedure my phone was at 17% after charging in recovery mode but didn't charge in normal mode after reboot. I also needed to toggle some setting regarding CQA in bootloader menu. Then everything went back to normal.
I will do this procedure to see if it solves my problem, remembering that my battery is in 0% and with it connected in the device it is only displaying the lightning, informing that the battery is without load.
what settings did you make regarding the CQA?

My device does not hold 5 seconds on bootloader because my battery is at 0% I believe the power supplied by the cable in the charger is not enough to keep it powered on. and now?
Original charger is definitely more than enough to keep phone on in bootloader mode. Try to make sure that usb C connection is dust and grease free.
Regarding CQA mode setting I can't remember exactly, but that is second thing.
Maybe even 5 seconds in bootloader should be just fine to navigate to recovery.
I wish you good luck, i was almost desperate when it firstly happened to me.
i had the same problem. after lot of trial and error i found a solution.
connect to power source (wall adaptor/modo battery mod.) get into bootloader menu and wait for 5 mins pressing vol up or down frequently.
then select reboot to recovery. on red triangle screen holding power button press and release volume up button one time. you will get into android stock recovery
select option wipe cache partition. and select yes when asked.
keep charging the device upto half hour in recovery mode and then select option reboot to bootloader.
after bootloader menu appears scroll down to BPTools and select it.
Your Phone will reboot and you will get Network and Your Phone will also charge normally.
Warning: Do not let your phone discharge to 0% or you might have to perform all above steps again.
This method worked for me as well. I recently replaced the battery on my Moto z force droid but couldn't get it to charge and signal was gone, after trying several things the Bp tools worked great, thanks dude.
