[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?

Please help! Computers will not recognise phone which now doesn't load the OS

I unlocked my HTC One X using the HTC software, no problems.
Installed Cyanogenmod using the wiki install. It worked, but once it was installed, no computer would recognise my phone any more. I've tried installing several drivers using the Android SDK and the guides here (Latest HTC Drivers), here (How to solve ADB : 'Device Not Found' error in Android), and here ([HOWTO] Installing HTC Drivers for adb/fastboot on Windows 8). Nothing worked.
Stupidly, I thought it wouldn't matter much and left it. But yesterday I tried updating Cyanogenmod to the latest stable 10.2.1. It caused my phone to simply show the "HTC quietly brilliant" logo and the restart constantly.
I've tried doing a restore, which didn't work. I've tried doing a factory reset, but all it does is load Clockworkmod recovery. And I can't simply "push" a rom onto the phone using cmd because no computers recognise my phone.
The phone turns on and charges just fine, but it repeatedly tries to start up and restarts. I CAN use HBOOT, Fastboot, and recovery though.
Any suggestions? Would be greatly appreciated, thanks!

you said you can use fastboot, so put the phone in hboot and enter fastboot mode, download the recoveery and flash it via fastboot using this command:
fastboot flash recovery recovery.img
(adapt your command to the recovery name )

Okay sweet, I managed to flash PhilZ recovery on. But when I try to mount the sd card, still nothing happens. I can flash stuff but I can't access the sd card from my pc.
I tried doing a factory reset using PhilZ but now the phone just sits on "HTC quietly brilliant" and doesn't start up, even after attempting to flash a new rom.

you have to mount the sdcard, you will find the option in "mounts and storage" menu... after you do this, wait some mins... maybe it'll take a little time, but sdcard will get mounted
have you flashed boot.img via fastboot? if you don't do that, phone won't boot even if you flash rom zip...

I did find it and tried to mount it but it didn't work. I can wait for a while but it shouldn't take that long?
I have tried flashing a few different ROMs (boot.img) via fastboot but none of them work, still stuck on "HTC quietly brilliant".
Is there a way to force install a kernel and rom using fastboot or recovery, without mounting the sd card?

yes, it might take 3-4 minutes to mount... anyway you don't have to mount sdcard to install a rom, only to copy it on sd to flash it later.... do the following steps in that order:
1) put the rom zip in sd if you don't have it yet (skip if you do)
2) enter fastboot and flash boot.img taken from zip
2a) fastboot flash boot boot.img
2b) fastboot erase cache
3) enter the recovery and choose "wipe to install a new rom"
4) select install zip from sdcard and install it (follow instructions)
5) first boot may take up to 10 mins, so be patient...
if you still have problems with that specfic rom, try another one and check if it boots... if you choose to install ViperX 4.0.6, search in th rom thread becuse some users have issues in flashing and you need to follow a particular procedure (i mean only wipe cache in recovery and full install in aroma)

Okay, FIXED now. I managed to restore the phone using some RUU and stock firmware packages. After that, I managed to flash ClockwordMod recovery - which actually allowed me to mount the sd card, which actually worked! So then it was an easy flash of kernel and install of CyanogenMod (for now).
Thank you so much for your help ! Didn't even know I'd be able to mount from recovery until you mentioned it several posts above.

[Q] ADB won't detect my phone

Hi, I have a rooted Desire 816 currently running unofficial CM12. Before this, it will detect my phone, and thats how I root it and install custom recovery, but now, I tried to go back to stock but I couldn't get adb to work. It kept saying ADB error no device found.
Any help? I've already installed the HTC driver, same. Went to fastboot mode, on the phone it says fastboot USB but nothing happened.

In CM12 did you go into developer settings and enable adb?

yes i did. and it even showed up in the status bar. but still the same.

Then you don't have the proper drivers. You know adb and fastboot are different right? The rooting process doesn't involve adb, only fastboot. They're separate things and require separate programs to work.

Yes. But fastboot not working either. It's stuck at <waiting for device> and I can't lock the bootloader or flash the firmware.

Try to redownload fastboot, and uninstall then reinstall the HTC drivers. If that doesn't work your screwed.

Try this, its a program that tethers internet from your phone to your pc. It has all the drivers you can possibly need. I use it when I cant find the drivers to my phone online. Friends use this when adb devices dosnt show up with anything. Its worked for me 100% of the time. http://pdanet.co/ (just download the windows exe file and follow the directions. I believe you have to keep your phone plugged in during installation but I cant remember)

How about this. Put a nandroid of stock on your device. Plug it in the PC and create a folder called "clockworkmod" then inside there create one called "backup" now usually you have to move your nandroid to the root of your phone but if you use Philz Recovery, you can change the directory it searches for backups so it will be on your regular internal memory.
Drew recommended a flashing program for recoveries before. It was called Rashr.
Use that to flash Philz recovery.
Then just flash the nandroid and boot up.
Now remove root, flash a stock recovery, then relock your bootloader. Factory restore afterwards and your done.
Also, make sure if you factory restore that your nandroid backup never used titanium backup to remove any system apps as it might make your device act out with force closes. If you have done that either find a full stock with just root backup or use an RUU.
Done.

Computer doesn't recognize Zenfone 2

My computers don't recognize my Asus Zenfone 2 Ze551ml. I've installed the intel drivers, the asus drivers, the google android drivers. I've restarted, tried different USB ports, tried different computers, and tried different USB wires but to no avail.
I originally wanted to unroot so that I could apply OTA updates but I couldn't get into recovery, all the phone does is restart into bootloader again. All the solutions I read require me to use ADB or get into recovery and since I can't get into recovery or get any computer to recognize the phone I seem to be stuck.
I haven't updated the OTA since 2.18.40.12 version. Can anyone help me figure out how to update my phone or get my computer to recognize it?
Thanks,

Please see the following for hardware reset/wipe cache partition procedure:
http://www.asus.com/us/support/FAQ/1011956/
Please see the following and scroll down for manual firmware update procedure:
http://www.asus.com/us/support/FAQ/1009748/
If you have any questions or concerns with Zenfone 2 please feel free to contact me direct at [email protected].
Sincerely,
ASUS_USA

Thanks for the reply Asus_USA,
Unfortunately, both the links you sent me don't work on my phone. For the first link (hardware reset/wipe cache partition) it asks me to go into fastboot mode, which I can do no problem, it then tells me to go into recovery mode. I can scroll down with my volume keys to the 'recovery mode' option but when I hit the power key to reboot the phone into recovery mode, it just reboots back into fastboot mode.
The second link (manual firmware update) asks me to download the update from the ASUS website, which I can do with no problem and then attach the phone to the computer and transfer the zip file to the root of my internal storage, I can't do this because the computer doesn't recognize my phone and therefore doesn't allow me to copy anything into it.
Let me know if you have any other ideas!

You can download the file directly to your phone from chrome by going to the download site on your phone. Also try setting your phone to PTP mode when it is plugged in and see if anything changes in device manager.

Or take out the sd card and copy to that, once back in phone you can then copy or move...

Tried it this way and then rebooted the phone. The phone recognized that there was an update file, and when I allowed it to install it rebooted into the Fastboot screen and then did nothing. I waited a half hour before touching the phone. When I rebooted the phone it didn't update and nothing had changed.

I tried downloading the file from online and the same thing happened as with the SD Card. When I restarted the phone it recognized that there was an update file and asked me if I wanted to install it. I clicked yes, it thought for about 30 seconds and then rebooted the phone into fastboot mode. Nothing happened after that and I had to choose the 'Reboot' option to start the phone back up; nothing had changed and the update did not work.
PTP mode doesn't seem to affect anything. My computer still doesn't recognize the phone.
I should also mention that the phone *does* charge when plugged into the computer.

Maybe u r having drivers issues

Your PC won't recognize it, even in fastboot mode?
If it does you can flash a new recovery in fast boot by using the adb tools. To test attach phone in fastboot mode to pc and type in "fastboot devices".
If it detects the phone you will see your serial number come up. Then reflash the pre-rooted image. it might replace the screwed up files in your recovery.
Instead of the ADB drivers only though, use the flashtools found here - http://forum.xda-developers.com/attachment.php?attachmentid=3301263&d=1431011927 Say thankyou to Shakalaka... I was having trouble using ADB, you might need to update to the latest drivers, but the flashboot tools worked with no problem...
You need to put the pre-root.img file in the folder and after connecting phone via usb hold shift, rightclick inside flashtools folder and select "open command window here" from drop down menu.
Then try the fastboot devices command.
Afterwards you can either flash the recovery again back to stock or flash the pre-rooted image and see if that fixes it.
You can find stock recovery,droidboot.img files and boot.img files here - http://forum.xda-developers.com/zenfone2/orig-development/rom-pre-root-img-t3079590
Again, BIG thanks to Shakalaka.

Instead of the ADB drivers only though, use the flashtools found here - http://forum.xda-developers.com/attachment.php?attachmentid=3301263&d=1431011927 Say thankyou to Shakalaka... I was having trouble using ADB, you might need to update to the latest drivers, but the flashboot tools worked with no problem...
You need to put the pre-root.img file in the folder and after connecting phone via usb hold shift, rightclick inside flashtools folder and select "open command window here" from drop down menu.
Then try the fastboot devices command.
Afterwards you can either flash the recovery again back to stock or flash the pre-rooted image and see if that fixes it.
You can find stock recovery,droidboot.img files and boot.img files here - http://forum.xda-developers.com/zenfone2/orig-development/rom-pre-root-img-t3079590
Again, BIG thanks to Shakalaka.

My computers don't recognize my phone even when it's on fastboot mode so I can't follow any of the steps

Would the solution for flashing recovery detailed in this thread help you ?

You would need to still have root.

Thanks for directing me to that thread, it looks like, unfortunately, I have lost root access over the course of trying different solutions... Anyone know of a way to allow terminal to access root without superuser?

i have the same problem, computer sees my device in fastboot but i cant flash anything through recovery, everything is whiped i have no system on phone now i tried everything.
when i use adb drivers suggested in post above it says outdated server and still doesnt see my device in recovery mod.
i tried on 2 computers
i tried stock recovery matching my stock rom
i tried twrp
in general it says on my phone"you need sdb 1.0.32 or higher" but i use 1.3 version (15 secs install)
any suggestions?
thats the first phone ive ever bricked and i'm panicking right now...

Hi everyone.
And @Kalkin19 @ma.ruda,
Could you both try to follow my steps on other similar thread?

Let me know if your adb problem is solved or not.
Edit: Seems this thread is so old! Someone bumped it by posting the same issue. But, yeah, at least, give a reply. :silly:

Sorry for such a delayed response, I haven't logged in and checked my messages in a while. This issue was fixed for me randomly. I kept plugging my phone into my computer and it eventually recognized it (after about 60 different tries). I quickly added adb, unlocked, rooted and have been having no issues since then. I appreciate your link! Hopefully it helps others in the future.

Stuck in TWRP and fastboot not working

Hello. I decided today to clean install the Pixel Experience 10 rom. I previously had a Pixel Experience 9.0 Pie. I did the following:
1. Booted into TWRP and selected Format Data
2. Everything is deleted, so it's time to flash a new rom. The guide says to go Advanced/ADB sideload and enter a command.
3. Command is not working. My phone is connected to the computer but it's not recognized. I can't even manually transfer it to the phone so i can install it via TWRP.
So i enter fastboot. Phone is recognized. When i type fastboot devices i get this:
Code:
C:\adb>fastboot devices
42abad9b fastboot
If i try to flash again a TWRP, my phone disconnects and it asks to reboot the phone by pressing a volume button. And i am stuck here. Nothing i can do. Any suggestions? I haven't done anything unusual. I am truly desperate. Any help will be appreciated.

Hi !
Did you bypass ARB with dummy.img before you flashed TWRP?
Do you use win 10, if you are change usb or use usb hub. If that doesn't help use win 7.
follow the link for details

Good luck and stay safe.

I already had TWRP from long ago. And i didn't even try to flash a new ROM. I just formatted Data. I have the TWRP version 3.3.1-0. But as i said, PC does not recognize phone in TWRP and i can't adb sideload any ROM because of it.

Go back to previous version of TWRP(latest is buggy) or use OrangeFox recovery.
But still if you lose custom recovery you need again start over and bypass ARB.
And check if your bootloader is still unlock.

I can't go to a previous version of TWRP. I can't flash any recovery via fastboot because of the problem i said at the first post. I somehow managed to boot into some previous versions of TWRP via a tool called TOOL_ALL_IN_ONE, but nothing changed. I had the same exact problems.
How will i check in my current status if bootloader is still unlocked?

Use this and post the result...
Code:
fastboot oem device-info
So you managed to get TWRP via TOOL_ALL_IN_ONE, ... when you are in TWRP flash TWRP again via TWRP or better flash OrangeFox Recovery(use SD CARD or adb push - for more info google it for adb commands), than reboot it directly into recovery again by TWRP option reboot to recovery... and now you can flash your ROM.
So make it simple
1st time you'll boot in TWRP by TOOL_ALL_IN_ONE,
than you'll flash recovery via TWRP and make it permanent,
Than you'll directly reboot to recovery via TWRP,
now you can wipe and flash your ROM.
Happy ending :highfive:

The problem was that i couldn't use ADB sideload because the phone wasn't recognized by the computer. And i fixed it in a very weird way, by connecting the phone to the PC monitor's USB hub and that way the phone was discovered by the computer. So i fastbootted the latest TWRP and then easily transferred the ROM i wanted to flash via TWRP. It's crazy that i spent all day just to connect the phone to a USB hub so it could work...
