Bricked Acer Iconia Tab One 10 (A3-B20) - Android Q&A, Help & Troubleshooting

Hi all,
I own the Acer A3-B20 and had it rooted some time ago with Kingroot. Installed a system update by Acer a few days ago and since then the tablet only boots in Recovery Mode. Resetting to factory defaults does not help, the filesystem integrity checker shows a few modified files.
Only viable option in recovery mode seems flashing a new firmware and I tried to do so with the currently available offical ROM from Acer: "AV0L0.B3-A20.RV03RC06.WW.GEN1". Flashing starts successfully but ends in the android screen of death (lying robot with red triangle).
Does anybody have a better idea on what to try? I haven't been able to find another firmware to try except the aforementioned.
Cheers,
Jarek

Try Wiping your System partition then doing a Clean Install of the ROM using Fastboot.
Hopefully there will be a option in your Recovery to restart the device in boot loader mode(that's fastboot).

Hi,
Thanks for your help. Unfortunately I'm not able to enter bootloader mode. Recovery mode has an option "Reboot to bootloader" which causes the tablet to power down, nothing else happens.
Also, booting up with Power+Volume Down/Up (tried both) only boots to the same recovery mode.

To access the recovery menu on my B3-A20, I use the Volume-Down by itself; The Power+Volume-up combination starts a Chinese factory test/debug menu.

[Q] [tf201] (unlocked) Prime bricked or not?

Dear community,
I tried to boot into CWM (installed via Rom Manager) but nothing happend after the reboot-to-recovery, invoked via Rom Manager. The tablet was stuck at boot, displaying the Asus logo. No animations and no error messages were displayed. I needed to press and hold power to reset my prime so it would boot my rom again. I was still able to load fastboot (power + volume down)
Next I tried to reboot-to-recovery using Goo Manager. The same issue occurred, stuck at startup, displaying the Asus logo, but now I am unable to recover from that state to load the rom!. When resetting my prime it is still stuck at displaying the Asus logo. No animations and no error message displayed. I can also no longer enter the menu using power+volume down...
I am afraid I perma-bricked my Prime but ofcourse hope it is not the case. Can anybody help me confirming my fear?
Thank you for helping me out!

That is bricked unfortunately.
CWM only ever worked on the ICS bootloader and there are warning everywhere on here never to use it.
You needed the correct version of TWRP for what bootloader you was on.
If you cannot get into the rom, the bootloader menu or you have nvflash backups that you created before then you are out of luck.
Hi flumpster, Thanks for clearing this up :good:
I think I have the similar problem. I have TF201 Android 4.1.2 installed and a PC Ubuntu 13.04 installed.
-First of all, I used unlocker releases by Asus. Then I loaded CWM by fastboot, but it didn't launch, I loaded CWM Touch, but it didn't launch, I loaded TWRP and again it didn't launch. When I tried to launch recovery rom every time it stuck at splashscreen.(It says booting recovery rom or smth like that)
-Then I tried to start unlocker again, it gave network error.(If you shut down the wifi it asks for internet, I think Asus collecting some information about prime.)
-Then I rooted my device. Again it stuck at splashscreen while trying to launch recovery rom. I reloaded recovery roms again it didn't work. I choose restart to recovery from the ROM MANAGER, it stuck again but nothing about "booting recovery rom" just "device is unlocked" writen. Then finally I installed CWM from ROM Manager again and I choose restart to recovery from GOO Manager. Boom! I think it tries to boot recovery rom in everytime. I can't boot android, I can't boot fastboot, power+volume down didn't work. Even I can't close it, it always restarts and I had to wait until the battery last.
So is there anything to do?

Did you ever find a fix for this ? Would of been a dam sight easier if there was rocker buttons on the side all it needs a cache and factory reset and it's fixed

techman20, have you ever solved this? I ran to exact same issue and have been tried different methods for the past 2 days. I'm new to Android so need community's help.
Here is the current state of my device (GT-B9150 Samsung Homesync):
- In order to get root, flashed ROM MJ1 (TUR version), followed this thread: http://forum.xda-developers.com/showthread.php?t=2497102
- After flash the device got very slow so I figured I need to wipe the data and cache partition
- There is no volume key of the device so I use adb to reboot to recovery mode (debug mode has been enabled earlier), again there is no key so I didn't know how to select in the screen (should have use adb command as well, I was not that familar with adb), instead I put into the command rm -r /data, then the device dead
- After reboot the device stuck in the bootloop: I see samsung logo and homesync logo, NO adb connection (I think the debugging mode is not on)
- I tried flash a few other versions of the ROM and it does not working as well, all stuck same at the bootloop
I figured if I can wipe the data and cache partition after a fresh installation of ROM the device could be saved.
Here are a few path that I see can solve this:
Option 1: Get into recovery mode, but I don't know the key combination, also adb is not working so seems can not use command line either
Option 2: Since I'm able to get into download mode, I can use Odin to flash some sort of bootloader with adb function, so that I can later use command to get into recovery mode
Option 3: Complete wipe out the device, re-partition using Odin
Since I'm new I don't exactly know if any options here makes sense and what are the risk for each. Also I don't have the pip for option 3. Would be great if any expert here can shed some light on, it's been bothered me for 2 entire days at weekend.
Thanks,
Is there anyone can please help me with this issue, or provide some insights?
Thanks

for boot loop you need to clean data and cache partition. To do that you need to go to recovery mode.
To do that, turn off the device , hold the power button. First you will see its power on, keep it pressed. And after 5s , you can home sync will rebooted to recovery.
Hi all, I know this is too old subject, but unfortunately I had my homesync flashed firmware through Odin and I did nand erase all, it is now stuck to Samsung homesync logo after booting. I know it is required wipe but how if no recovery is installed into the original firmware? any thought?

Hi all.
Help me, I can't find PIT file for Samsung Homesync (GT-B9150).

Stuck at samsung logo! (volume down button not working.)

Hi. I'm new here, and I really need help!
It started today when I'm tired of a disaster lagging using android 5.1.1 rom on my Galaxy tab 10.1 (GT-P7500).
So, I decided to flash a stock rom to go back to honeycomb 3.2
And basically, a volume down button on my tablet is broken. so I won't be able to reboot in recovery mode.
I tried reboot in download mode by pressing power + volume up button but it won't work either.
Then I managed to reboot in download mode and use Odin to flash a rom by using adb cmd but I didn't boot to recovery mode and wipe data/factory reset first(I don't know if this has something to do with this problem.)
And that brought me to a dead end problem.. Stuck at the logo while booting up. :crying:
I don't really know what else to do or is there some hope with this situation. I plugged a usb to my pc while in logo screen and it showed up as SAMSUNG_Android so when I check by typing adb devices in command it's there but can't get it to work since adb required debugging mode.
I think I will probably end up order a new button for replacement but I feel like I should ask a professionals first.

[Q] Oppo Neo 5 Softbricked

Hi guys, I really need your help.
I'm new at this rooting stuffs and I tried to root my Oppo Neo 5.
I tried so many softwares like OneClickRoot, FramaRoot, and Kingroot but none seemed to work.
So I resorted to an app called oppo tools
It worked at first but I got really annoyed when my status bar suddenly colored to red when my phone discharges to 15% so I unrooted my phone and rooted back again. I really thought that was going to fix my problem but that's where the bootloop issue started.
I tried to flash some custom recovery zip but it failed since I only have a stock recovery.
But the thing is, I found a guide that says to rename the clockworkrecovery img to PG86IMG.zip.
So I did tried that and as soon as I flashed the zip from my stock recovery, my phone hanged.
I long-pressed the power button to restart and boot into recovery mode but nothing seems to happen.
I'll try to explain a bit more on how it looks when I boot my device.
When it boots normally (I mean not pressing the volume to enter recovery mode) it will only show the logo but when I try to go into recovery mode it will show the logo with a little text on the lower left portion "Recovery Mode"
Before I flashed the PG86IMG.zip, recovery mode was still working and the charging screen when off is working too.
but after I flashed the zip, every time I try to recovery mode the logo shows up with the little text but RECOVERY MODE isn't working. When I charge my phone it automatically boots up and shows the logo and text like it's trying to go recovery mode (I'm just trying to charge? It's going to recovery mode)
I tried using "adb devices" on cmd but it's not detecting any devices.
I'm really out of ideas guys, I know not all people use this model but what would be your suggestion?
A suggestion on how to fix this would really be appreciated :good:
I'm sorry I'm really new at this, please correct me if I did something wrong starting this thread. :angel:

Oh, I'm sorry, I didn't notice.
Lately I can't access the recovery mode but now
I'm currently on Boot-loop and I can enter into recovery.
The ColorOS recovery mode only have limited function that I can mess around.
It only has the apply update, wipe data and cache, reboot, power off and system file verification.
As always I already did wipe the data and cache but nothing happens. Still boot-loop.
What should I do?

You made a soft brick, not to worry flash it with correct stock firmware, if the phone is in warranty than ask them to do flash, this will take approx 10-30min. If it isn't in warranty than you should try it own or else pay some amount and the rest they will do.

Switched ROMS (Evolution X -> Nusantara) -> NOW Bootloop

Hi Community,
I read some posts how to fix my Problem, but i cant go to a service Point.
So I was using the Evolution X for a long Time (Installed with TWRP 3.1.0).
And now i wanted to change to the Nusantara Project (Vanilla), I did a clean Flash, everything worked i could access the System.
Than i had problems installing Play Store, so i rebooted into Recovery via the System. But now im Stuck in the Loop.
Can i Somehow connect my Phone to the PC and Reset?
Can someone tell me if i Hard/soft bricked my phone ?
Just a little advice, would be really appreciated.
Thanks a lot
Go to TWRP, wipe system, cache, data and dalvik. Now flash nusantra and whichever GApps are recommended for it (if there are no recommendations then use OpenGApps, make sure the architecture is correct). Now wipe dalvik and restart. Sometimes, certain roms begin to bootloop if you boot into the rom first, then try to install gapps later.
If you still have issues, just reflash the stock rom.
I cant access the TWRP anymore, im just stuck on the Bootloader, no matter how i turn on The Phone (Volume Up + Power ON ), (Volume Down + Power), (All 3 Buttons)
Nothing works anymore i dont understand ....
Im searching the net but i cant go to fastboot or something else, its just keeps on rebooting ...
So it's bootlooping, but you cant access recovery?
When the screen turns off, press the key combo and it should go to recovery.
Your best bet is to take it to a service centre, but if that really isn't possible for you, then wait for its battery to drain completely, then when you plug in the charger, instead of turning the phone on, press the key combo to enter the recovery. From there, wipe and flash some other OS.
I've also heard that certain versions of TWRP don't support some roms, leading to a bootloop. In that case, you'll have to use orangefox recovery to flash the rom (orangefox is flashable via twrp)
Yes its Bootlooping.
When i turn it on, on the Left Corner "Recovery Mode" blinks for one second. Than the usual Text appears:
"Orange State
Your Device has been unlocked and cant be trusted
Your Device will boot in 5 Seconds".
So after a couple of seconds (around 10-20 sec)
It turns off and immediately on again. I Just can turn it OFF when i hold all 3 Buttons.
Than i try starting it with Volume up + Power / Volume down + Power, But i cant access Recovery or TWRP.
So i should wait til the battery gets low and try it again ?
Like i said, my custom Rom (Evolutionx) and TWRP just worked fine. I dont know man ...
Well since your bootloader is unlocked, try flashing the stock rom again. Look for a tutorial and follow it.
Hi I managed to unbrick my device with this guide, and im back on a stock rom
Unbrick
i ran following commands to get to my custom rom:
I run adb reboot bootloader,
add executed following commands.
(Pitch Black recovery 3.1)
- adb reboot bootloader
- fastboot flash recovery recovery.img
-fasboot reboot recovery
It just hang up and booted after a while into the normal system.
But im not able to get to the recovery menu ?
When I restart and hold Volume up + Power, i go in a loop and the phone keeps restarting over and over again.
what have i Fu**ed up ?
Do i need another recovery tool ?
sorry guys, i appreciate your help a lot tho !
EDIT: Is my bootloader unlocked ?
I can access via "adb reboot bootloader" the phone
and on the blackscreen on the phone it is written:
oppo verfiy pass
fastboot_unlock_verify ok
Update:
So i tried some Stuff and i got Red State. No Problem i Unbricked it once again and now im on Stock Android 10.
Now im Trying to enable the bootloader again.
I downloaded the In Depth Test_Realme_6.apk but i keep getting the Error that i should update the system.
So should i update the system ?
I cant find a CURRENT Tutorial to make this work, please help...
If you cant find a tutorial for your version, why not downgrade back to a previous one if possible.
