[Q] NOOB bricked acer a100 help!

I tried using the simple root and clockwork mod method and now my a100 keeps cycling thru bootloaderversion 0.03.06-ics-ics (unlock mode) with green acer logo. If I reboot holding power+down sd update command recovery
update_package=sd card update.zip
booting recovery kernal image
then it starts cycling again.
Please can someone help!

same
Same thing here (or at least very similar). Hoping there's a simple solution like the "Odin back to stock" I can do on my SGS phone.

are you sure that the bootloader say "unlock mode"?
If so, then try this.
try this
Install the USB drivers on your PC if you haven't done it already. ( http://global-download.acer.com/GDF...A TAB&Step3=A100&OS=a08&LC=en&BC=Acer&SC=PA_6 )
install android SDK. ( http://developer.android.com/sdk/index.html )
copy the update.zip file to your SD card root.
download TWRP recovery ( http://forum.xda-developers.com/showthread.php?t=1608152 ) and place it in the platform-tools dir where the SDK was installed ( ex. C:\Program Files\Android\android-sdk\platform-tools )
Once all that is done follow these steps
1) boot the tablet to fastboot mode
2) run command prompt on PC (cmd.exe)
3) cd to the platorm-tools dir
4) type the following lines one at a time.
adb.exe
fastboot erase recovery
fastboot flash recovery NAMEOFRECOVERY.img (ex. recovery-A100ICS-TWRP.img)
5) hold the vol down button on the tablet
6) type fastboot reboot.
The tablet should now reboot to the recovery program. Goto settings and mount the external SD card, then flash the update.zip by going to install.
Hope this helps

Did you rename/delete /etc/install-recovery.sh ?
I think you're not. Try to make hard reset, then boot normaly rename/delete this file and after that flash recovery again, it should work.
All it's explained here.

Thank you

Okay, I downloaded everything but my computer doesnt recognize my a100 anymore, only if I put the tablet into fastboot then it see's it. My tablet just keeps on rebooting itself repeatedly unless I go into fastboot. Please tell me I dont have a paperweight.

were getting close
Blackshinobi or anyone that can help,
I'm getting close. I make it to: "fast boot flash recovey" cmd prompt
I get two different errors depending hoew I type the cmd prompt:
1. "fastboot flash recovery recovery-A100ICS-TWRP.img"
error (can not load recovery-A100ICS-TWRP.img)
2. "fastboot flash recovery-A100ICS-TWRP.img"
error ( cannort determine image file name for 'recovery-A100ICS-TWRP.img)
I was a little confuse on proper cmd line prompt, but I'm thinking #2 is the correct way.
Thanks so much for your help!

That's awesome news!!!
Number 1 is the correct command.
Just making sure you are actually in fastboot (bootloader) mode. On the command-promt type "fastboot devices", if you see the result below, then you're good
? fastboot (yes that's a question mark)
Now be sure you are in the directory with the recovery image and issue number 1 command (fastboot flash recovery whatever-recovery.img). If you get some errors, be sure to check the MD5 hash of the recovery image cuz it could be a corrupted download.
Of course, you can't flash the custom recovery if you still have a locked bootloader.

you guys rock..even closer
Thank-you everyone ..I am soooo close. I did get the recovery image to load (I accidently had it in android-sdk and not platform-tools...oooops my bad). Now I can reboot to recovery and install the update.zip off my external sd card. However after I install the update.zip and reboot, I still get stuck on the acer screen (bootloader version 0.03.06-ICS (Unlock Mode) at top with acer logo in green at bottom.
Which update.zip am I suppose to be using? Currently I am trying to install one of the stock ROMS from the developer section of this forum. Am I suppose to be using a specific one?
Thanks again, I know I'm close. My tablet has been brick'd for weeks and I'm dedicated to getting it back now that I have time.

Congrats resurrecting your tab! Gotta be a great relief!
How about Flexreaper ROM? It will require full wipe before flashing: in recovery wipe/factory reset, wipe system, wipe cache, wipe dalvik cache, flash Flexreaper ROM zip file. This is basic guide, follow detailed instructions on this ROM thread (link is in my sig).
Sent from my A100 using xda premium

not quite recovered yet. I still get the hang on Acer screen. anyone know why? I will try flexreaper

I'm BACK
Thanks to all. I'm back up. flexreaper did work.. I hope the guy who actually started this thread is as lucky.

Not so lucky

Power down the unit. Set screen lock in the up position. Hold volume down and power. When powered on keep holding the vol down button. Then toggle the screen lock to down.
That should do a factory reset.
Then put a stock rom in the root of SD Card. Volume up then power until let the tablet recover.
This worked for me.

did u install the drivers from an earlier post? Also when you power up you your tablet you need to boot into fastboot mode? You're certain you have done both of these things?

I am unable to connect to, my pc doesnt recognize my acer anymore...unless by sd card you mean external card? Thank you for trying to help. I'm a serious noob but trying hard.

i'm in a similar situation. i accidentally deleted the build.prop file and rebooted. now it only displays a black screen after the acer logo drops out. my boot loader is locked but i cant install the mtp usb drivers to fix anything. think i have a paperweight now.

tried. i had no alternative recovery on it. i could not get the sd card mounted to push the zip to it. both adb and fast boot wont see my tablet. every attempt at unlocking fast boot wouldn't work. I tried to check in device manager to see if it was connected, the driver was working but it had an error message "Device can not start (Code 10)"

My pc only sees my tablet when I boot it into fastboot mode and sees it as an adb interface...Is there anything I can do from there?

[Q] final steps when installing custom recovery

Good night.
I have to ask for help when trying to install custom recovery on this awesome machine.
I have done all steps and wen good, but when doing the final steps:
6) Use fastboot to boot CWM by running "fastboot boot /path/to/OuyaCWMrecovery6.0.3.2.img". This boots from our CWM recovery without writing to any partitions.
When writing this, says "wating for device" and dont advance.
I searched into ouya forums but i could not find the solution.
Also, drivers,sdk and su files are correctly installed.
Thanks for help

Usually that happens when the device isn't at the bootloader. Did you run "adb reboot bootloader" to get to the bootloader?
Sent from my Nexus 7 using xda premium

Yes, i followed all steps, including "adb reboot bootloader" and then waited 30 seconds, just the way its written
At this stage, ouya its switched on but not image, so i suposed i am into bootloader

MIght be a driver issue. On mine the first time I booted into fastboot mode I had to go into device manager, found the android device with a yellow triangle, and had to install the drivers manually with "have disk". Hope this helps.

Same thing happened to me, I never saw anything until I fastbooted the .img. And then I had to try it on 3 displays before one would show CWM. However after I flashed the .zip I have since tried all the displays and they all have worked every time.

Wow problem solved!
In devices administrator, there was one small called "fastboot" with yellow triangle.
I manually installed a driver called "android bootloader interface" and now it is working
thanks a lot!!!

No problem, always glad to help.

Now im fighting to get multi usb support via using a 5 ports usb-hub, i will write if i can ge througt

Can you post about that in the USB thread ? I just bought an active USB cable and 4 port hub, I hope they weren't a waste. I'll still get some use on my laptop, but not enough to justify the purchase.

[Q] Need help getting a zip onto device while in TWRP

Hello all this is my first post and first time trying to root/unlock a device and am having a fun but slightly frustrating time doing so. I was following a guide and got to this step.
2. Now copy/move the downloaded SuperSU file to your Sdcard.
How do I do this when my device is in fastboot mode?
I am in the TWRP but don't understand the steps to getting the SuperSU zip file onto my device in this state.
Edit: My device is no longer recognized as an ADB device in device manager when I am in TWRP. I cannot use ADB sideloader to transfer a file. Now when I use the commad "adb devices" nothing is found but earlier it showed my device before I put TWRP on.
When it is in bootloader it says "Android Bootloader Interface" in device manager.
Once I enter TWRP that disappears and under "Other devices" it is showing up as "flo" which is what is says the product name is when in fastboot. Really confused as this is my first device I have unlocked/rooted on my own. I figured it would be way easier than this but I am noob so I guess I should have expected this.

Can't you just put the SuperSU update.zip on the /sdcard (virtual) while in android, prior to starting twrp?

I am stuck in either bootloader or the TWRP... If I try to start my device it just hangs on the little nexus "X" forever like it was the first time starting my device and never loads past it. Is there a way I can just reset all this to factory and start over? Ty for responding.

Soft bricked OPO3, Fastboot with no recovery

Hi guys,
Rooted Oneplus 3 is soft bricked. Please help me!!! :crying:
:crying:Quick desription: Fastboot formatted it. My PC detects it.
Tried to Fastboot flash latest TWRP ("twrp-3.0.2-0-oneplus3.img") via CMD Prompt.
After that I get a message saying that the processed was "finished" (within 0.802s!).
Now I reboot+volume down and bootloop continues. Phone starts, I see the normal warnings I used to get after rooting it. Then I see the Oneplus logo for a fraction of a second and then it boots again and the process repeats itself.
I think it may be worth mentioning that the reason all this happened is an encryption problem that occurred while I was flashing a rom update with TWRP: After the flashing finished, got an error saying "unable to mount storage". Wiped cache+dalvik and then restarted. Got a black screen that did not display any signs of life after several minutes. Then turned it off and on by long press on the power button. Then I got an error saying that the encyption process was disrupted and that I have to wipe my phone (strange given that I did not select any encryption button in TWRP). Anyhow, then I fastboot formatted the phone and that's it.
Thank so much for anyone who can help!!!

fastboot flash recovery recovery.img (I recommend blu_spark's TWRP) reboot to recovery, if it doesn't work, try:
fastboot boot recovery recovery.img
See if you boot to recovery and then try flashing a custom ROM.

Hi Fobos, thanks for responding quickly.
I tried using fastboot boot command (with twrp-3.0.2-0-oneplus3.img). No luck with that.
Also, didn't find a downloadable blu_spark *.img version for twrp recovery. would you be so kind to add a link?
Thank you.

Now I think it's hard bricked ( Help!!!
Phone just stopped responding. Mostly doesn't respond. Occasionaly turns on for a nano second, flashes the +1 logo and turns off. Most of the time it doesnt even do that any more when I press (long / short press) the power button!
Somebody help, please!!

Keep calm and breath in. I was in the same situation.
Take a breath.
So, you have 2 ways depending on what you want. You can either go back to full stock with a flashing tool or you can install a custom recovery and then installing a custom rom (or stock one). I suggest the flashing tool.
Just follow the steps here: https://forum.xda-developers.com/oneplus-3t/how-to/unbrick-unbrick-tutorial-oneplus-3t-t3515306 and if you have any question come back here and ask them.
Good luck.

then flash recovery using

Hey Keyembe, thanks for the reply...
Tried to follow the instructions you posted. Did everything to allow unsigned drivers to be installed. Disabled it on from the advanced boot settings, and - when that didn't work, also running on test mode. Neither options work:
In the device manager I right click the android device (currently in fastboot mode), which is installed with Google drivers. I try to update the driver software to the unsigned driver and I get an error saying it's not compatible with my system (Win10 Pro) and that I should make sure it is compatible with an x64 based system.
What now?

Hi Anup!
Thanks for the link to the Blu_Spark version of TWRP.
On CMD Prompt, tried to format recovery, console stopped responding. "Fastboot format recovery"...Just stops responding
Also tried "Fastboot delete recovery". I get a message saying "deleting recovery..." then also stops responding. Nothing happens from there.
I tried to use the OPO3 Root Toolkit. It does detect the fastboot device, but when I try to flash or boot or do anything else other than detection, it is unable to find the device. Says operation failed.
What now? :crying:

Check your cable (try another one), even reinstall your adb drivers on your machine (if Windows).
Let the device charge for 30 minutes at least then retry (charge with new cable too).

Firstly, plug your phone on your computer in recovery mode or fastboot mode.
When you go in cmd and you type "adb devices" do you get anything?
If that works and you still can access recovery, you can install stock rom available on the OnePlus site. Here's a link : http://downloads.oneplus.net/oneplus-3t/oneplus_3t_oxygenos_4.1.3/
Boot into recovery, then install from adb.

Thanks mate, followed the instructions on this post. I never get the device to be detected as Qualcomm. All I get is "Android Phone". I did install the Qualcomm drivers despite the warning I got for installing unsigned drivers. Installation went OK. When I go to the device manager again I still identifies the device as android phone. Also when I click "Have Disk" and select the qualcomm drivers I get an error saying they are incompatible with the device or with an x64 based system (regardless of them being signed or not).
Any ideas?

Strange. Are you sure you turned off Driver Signature Enforcement?
When you hold the power button 10 seconds and plug the phone in, it should not be on. The screen should stay black. (looks like its off)
So make sure it's not trying to boot, because then it probably shows up as Android Phonee again.

Go to Fastboot type 'fastboot erase userdata' (you have to reflash OOS tho.. Make sure you are on the latest TWRP. I'm not a fan of Bluspark but his TWRP is currently more up 2 date.

XT1676 - Stuck in Unlocked Bootloader, after Wipe Cache(?!)

XT1676 Moto G5, Fine Gold, 16GB

Problem: Stuck in unlocked Bootloader
Hi all,
i am stuck on bootloader and cant get out.
On my PC I have "Minimal ADB and Fastboot"(v. 1.4.2.) installed and after i open a command prompt(admin) and type
- "fastboot devices" my phone is listed as <NR> fastboot
so that works as the only positive thing i can say
- "adb reboot", *daemon not running. starting it now on port 5037*
*daemon started successfully*
error: no devices/ emulators found
- "adb reconnect", error: no devices/ emulators found
i am not into the adb commands at all, i am a dummy and i would be so glad if someone could lead me out of my problem.
Maybe a word how i got into there:
1) i installed the minimal adb and fastboot(v1.4.2.)
2) i unlocked the bootloader by doing that over the Motorola UNLOCK Bootloader site
3) then i rooted & Flash Twrp Recovery (twrp-3.1.1-0-cedric)
with "fastboot flash recovery twrp-3.1.1-0-cedric.img"
4) first time entered into twrp recovery and i did the following:
A) a factory wipe-> reboot back to recovery mode->
B) install no-verity-opt-encrypt-5.1-> reboot and let system start before i turn off phone and enter bootloader(vol down+start) again
C) after entering recovery mode again, i install Magisk-v11.6 -> reboot->
D) now everything seemed to work, the system started properly rooted.
E) but then i decided to flash once again the Magisk-v11.6 followed by wipe data/ factory reset cause i wanted to completly do the flashing all over.
(dont ask me why i did it.. i could explain and tell you my intention but well it happened anyway and brought me to where i am stuck now)
but that was on this move not all yet: i also wipe dalvik cache
so after wipedalvik/ cache , since that moment i couldnt access to my SD Card anymore as it simply didnt show up anymore.
after a restart i was my first time in an endless bootloop of that Screen with "Erasing"(, the letters sourrounded by a spectral colored circle)
i had to disconnect the phone from power . also i tried to remove the battery for a day. but it would only get me back into that bootloop and only get me out by removing the battery...
i dont know anymore what happened then when the phone now got stuck in the bootloader instead of the bootloop. But yea, now i am stuck here, appreciating any help :highfive:

...shows up but i cant get any adb commands to work tho ofc i am a dummy at it...

oh my, i just helped myself by reading my first poste here on the forum from 2016.
i made it now to start twrp by downloading the twrp_cedric_3.1.1-0 once again putting the recovery in my adb folder and type
<fastboot flash recovery twrp.img>
followed by <fastboot reboot-bootloader>
i am curious if i can get going now and if my SD card will be read and if i can get a new flash going...

now back in twrp i go first again to wipe/ factory reset.
now going to reboot, and reboot back into recovery. only gets me back to bootloader from where i can enter twrp manually now(but there is already an indication of the problem i have?)
also before the reboot, it doesnt ask me to install the twrp app anymore where i usually choose "do not install".
now i go to install the <no-verity-opt-encrypt-5.1>, flashing it successfully as it says at the end of the process but there is also some error message in the log before the ...done:
Failed to mount '/data' (invalid argument)
now i thought i should be able to boot the system again but i only get back into the bootloader...
can someone help me how to proceed correctly?
did i miss something to flash?

For failed mount data goto wipe & select format data (option on the right)
Reboot to recovery
For always going into recovery either you don't have a rom installed or read the faq section on my twrp thread as the answer is there

First of all thanks TheFixItMan, that you are behind it and your thread looks really cool and i will immediatly read and try to understand it!
For now i am stuck in the following:

the process shows successfully and "...done" but in the log there is a line of red letter:

<White Letter> You may need to reboot recovery to be able to use / data again.
i went back and to reboot and recovery.
but recovery wouldnt be booted but i get back to the bootloader(maybe that is still an indication of the problem i have here?)
manually entered recovery i did the select format data again but <red letter> line remains.

You have to select recovery from the bootloader menu to enter recovery
You can also type in a terminal window whilst phone connected to pc in fastboot
fastboot erase userdata
This will erase all internal data (the same as format data in twrp)

Important Notes For Stock Rom Users
When you first start TWRP it will ask you to swipe to allow modifications - If you do this your stock rom will no longer boot unless you disable dm-verity.
This can be done either by flashing a disable dm-verity zip or by flashing SuperSu zip which will disable it for you
Click to expand...
Click to collapse
ok, stock rom didnt boot so i flashed the "no-verity-opt-encrypt-5.1" .zip
and voila, i could boot the stock again finally! yipie!
but three things i noticed:
1) the boot progress is suspicous / wrong/ stuck at a moment:
"hello" and "moto" i still see and before the letters of moto start spinning around, the screen freezes for like 2-3 seconds and the next ting i see is the red mouth and cameleon and so on
2) i tried to test camera real quick and it says camera is busy
camera unable to start. if this repeats please power off your phone and restart.
(i did already 5 restarts now and still same problem)
anyway, i wanted to install a ROM now, something like Cyanogenmod.
in this context i wonder what the Magisk-v11.6 does? Does it just give superuser permission and is it always required?
3) system only gives me option to Power Off System(no reboot possible)
and that power off and turn on always gets me first into bootloader tho i dont press vol down+start
Edit:
ok, i have here 3 issues still but it goes offtopic already. i throw a thanks first of all at TheFixItMan and then i think thread cna be closed.
I will soon try to install a ROM, like LineageOS 15.1 , and hope that my previous 3 issues will be solved in the process. . .

Cyanogenmod is now lineageos
Use the latest version of magisk to root (see official magisk thread on xda)
You can run modules to mod phone without tripping integrity or dm-verity which if false will stop apps that check if you are rooted from working
Magisk hide can hide apps from detecting you are rooted on a per app selected basis

Phone should power off normally
If it can't be started normally without going in bootloader and selecting normal startup see my faqs in twrp thread & follow guide to wiping the misc partition
Note if flashing lineageos 15.1 you will require the 64bit version of TWRP available on the lineageos thread - I did not compile this & don't support it
It also doesn't support encryption as far as I know so if you are encrypted you will need to format data & remove it else the rom will get stuck at the decryption screen

that was not exactly the problem. my problem is that either i press restart system from system or from recovery, i first get a stop at the bootloader. from there i can just toggle to START and confirm. then my system boots. its just that i first need to confirm in bootloader the Start, always!
at this point i tried now anyways from your Official TWRP For Moto G5 Cedric- Thread |||||| your solution from your faq. But yea, it obviously doesnt fit my problem cause putting the lines in cmd prompt gave me that result and boot still does a stop at bootloader.. before i can start system or recovery..
So yea, after the first codeline didnt trigger for an unknown reason for me...
i hadnt the courage to even try the second more relevant codeline!

btw, Thx a lot for the information, i appreciate it! i choose LineageOs 15.1 and it runs now. atm i am reading myself into magisk. Also big thanks for your tipp looking up the official thread.

That error means your phone is not connected to your pc
Make sure you have enabled adb debugging in phones dev settings before booting into recovery
If you type
adb devices
It will list all devices attached
Once your device is listed the commands will work

and you think that your commands fromyour solution here helps me with my issue that i can start straight to everywhere i want? Cause atm I just always have to go over the bootloader -"stop". From there i have then to manually "START" in order to start system (now: LineageOS 15.1:victory or where i have to manually toggle down to "RECOVERY MODE" and start TWRP.
Well, i would give it a try, but yea dunno what i am doing wrong here atm. i just realized that the command "adb devices" never worked for me yet, cause i got in conflict with the command fastboot adb devices which effectivly works for me. Cause before i installed lineageOS 15.1 i had to flash the twrp cedric 3.2.1-0 x64. i did that over the adb command prompt:
Code:
fastboot flash recovery twrp.img
and in that process i even let my phone restart to bootloader with
Code:
fastboot reboot bootloader
.
now i went to tab build nummer 7 times-> dev options "on" -> android debugging enabled.
when i go to bootloader now or to recovery, and connect my device, for a strange reason in command prompt "adb devices" shows that:
... i dont know why the cmd "adb devices" doesnt show my device. maybe there is a twrp setting i need to change?

Does it display a device when the phone is fully booted
If yes than the recovery you are using doesn't support adb (my official recovery does)
If no I recommend downloading the full android sdk and using the adb that comes with that (you will find it in the platform tools folder where you installed it)

Hello, thx for your support.
I linked the wrong picture. This Screeny shows the related cmd (when dev enabled, booted to recovery, connected via usb to pc and typed adb devices).

it shows the same like linked above and when in recovery mode
so no , the 64bit version of twrp cedric 3.2.1-0 prolly isnt the problem.

ok i will try that. and the command prompt i have to open from the directoryy<platform tools folder> then right?
would you deinstall minimal ADB and fastboot before installing full android sdk?

still my phone isnt found
- sdk tools installed
- dev enabled
- adb debugging enabled
- command prompt opened at "...\android-sdk\platform-tools"
either in recovery nor in booted system nor in bootloader "adb devices" finds my phone
so the problem with the "bootstop" (have always to manually press "START" at bootloader) persists..
oh wait... i am not connected as admin! is it possible to open an admin command promp:silly:t?
so i am am reading here atm how to open command prompt in specific folder(platform-tools)
but wife is waiting for dinner so i better do that first..

On windows 7 - hold shift then right click a white empty space of the window where adb is & select open command prompt here
Windows 7 or 10 - search for cmd then right click on cmd and select run as administrator then navigate using cd commands to adb location or copy & paste location (if any spaces in path then put the entire path in quotation marks)

i use win7 and cd'ing to the path was almost getting annoying
as screenshot shows, it still doesnt work

in my desperation i deinstalled now all adb drivers(minimal+ sdk)
ran a ccleaner and cleaned registry and reinstalled minimal adb again (btw, there was a new version by now out, 1.4.3)
so the episodes still goes on and i could figure out some new details
because i bought the same phone again for a relative who needed a phone..
in the process of setting it up correctly( thankfully xda is around ) i enabled dev options and the adb debugging
here is the result for the new phone
that shows now that executing as admin or standard user wasnt the problem. i just did it as standard user..
then i thought "hey cool, wait, i connect now my own G5 and see if i can get the phones' Nr displayed there and make sure my phone can communicate with my pc over adb( dunno if the sentence just made sense- greetz from a dummy)"
what happened is shown in this screenshot .. same picture as before! :crying:
(dont get irritated by the screeny because i used the same command prompt for
first, the new phone and
second, my "old" phone which doesnt boot properly, if you look at the command and the result
i am lost!
is it possible to reinstall a bootloader? or how come my phone doesnt communicate with the pc anymore?
and how come that effects the booting process so that i always get this "stop" at the bootloader although i pressed for a restart?
can i do any more tests that indicates what problem i have here?
