Bricked A100

Okay so I have in my posession a Iconia A100 and it gets stuck at the white Acer logo. If I hold Vol Up & Power itll say:
Erasing Cache before SD Update...
SD update cmd: recovery
--update_package=SDCARD:uodate.zip
Booting recovery kernel image
It'll just hang there forever. I've tried putting a copy of stock ROM on the Sdcard and renaming it update.zip and it'll just hang there also.
Ive tried the reset button and nothing.
I really dont know what else to try, I'm new with messing with a A100.
The tab was fine, and was powered down normally and now it wont start.

Make sure you rename it to "update" (zip is the extension, not a part of the name). Also, make sure the file is placed in the root of your external SD card. If this still doesn't work, you could try resetting the tab via the pinhole.

Have you tried a factory reset? Note you will loose all your data on the internal.
With the tablet off, press the volume up (rocker farthest from the corner) and the power button until it vibrates, then release the power button and switch the screen lock back and forth until 'erasing user data' comes up (make sure the volume rocker gets held throughout the process).

Theonew, i tried that before and nothing.
Romman0, I just tried what you said and once Erasing user data pops up, it says something underneath it, and it goes off, vibrates and goes right back to the white Acer logo. It does all of this in less than 5 seconds...
Thanks for the suggestions so far guys
Im still stuck /:
Edit: it says erasing cache under erasing user data and then reboots quickly

It failed because it cannot see your SD Card. Check that it is freshly formatted (FAT32) and is inserted completely. Also make sure that your device is charged, it might turn the card slot off to save power.

[Q] Phone soft bricked? Unable to used ADB or Memory Card

Hello everyone,
I got my AT&T HTC M9 yesterday with 1.32.502.9. I unlocked the bootloader and installed TWRP successfully. I tried Installing Android Revolution 4.1 and didn't noticed the installation failed. When I restarted the phone it got stuck on the HTC logo. Someone after messing with the phone I ended up loosing TWRP and I'm back to the stock recovery with only these options:
reboot system now
apply updates from ADB
wipe data/fatory reset
wipe cache partition
reboot to bootloader
power down
view recovery logs
apply from phone storage
apply from sd card
My phone is stuck at the logo screen and I cannot sideload or flash anything from the SD memory card or phone storage. My phone gives me an error when I try to flash from the SD card and my computer now does not detect my M9 (all drivers were installed previously as well as the SDK)
I don't want to do anything else yet because I'm afraid I will make things worse. Could any body advice me on how to fix my phone?
Thank you!

I was able to fix it.

You have to switch to the download mode on your M9 and use the fastboot command to flash a custom recovery (TWRP2050 worked for me). Make sure your SDK is up to date and you download and install all the HTC drivers for the M9.
This might help: http://forum.xda-developers.com/one-m9/general/guide-root-install-twrp-htc-one-m9-t3061133

Shut the phone off,wait 10 seconds then hold volume down and start button. After a few seconds, it wil vibrate, release the buttons and it should start in donwload mode (black background).

Turn on you phone and wait about 10 seconds after seeing the HTC logo. Hold down the volume up button and power button for a few seconds until the phone vibrates, as soon as that happens switch to the volume down button and power button that should put the phone in "download mode." Connect your phone to your PC. On your command prompt you can type "fastboot devices" to check and make sure your phone is good to go. After that, you should be able to flash TWRP which in turn would allow you to flash a custom rom and fix your phone.

please be patient
I don`t have m9 now but if you do this solution,maybe your phone boot up again ( this solution works on m8 )
I don`t think your phone bricked or damaged memory
you can do this solution,maybe your phone fixed !
1- charge your phone then update the htc usb driver and adb tools
2- then boot to the bootloader and flash the latest twrp recovery again ( don`t forgot do erase cache)
3- download other rom like viper rom then copy it on the flash memory ( to install rom with otg cable and flash memory)
4-do full wipe ( internal and external memory - system - cache - dalvik cache)
5- install rom from flash memory and do full wipe again in aroma installer
6- then restart your phone and wait to phone boot up again
7- if don`t boot up,go to the bootloader and flash boot.img from rom ( you should extract rom to see it )
after all you can s-off your phone if you like
good work:good:

Thanks for replying but I was able to fix my phone a few hours after. Those are the right steps but you're missing some details. HTC has now changed things a bit and added the "download mode." Flashing in bootloader does not work any more.

Glad your all sorted !

Me 2 help !!!!

Deleted OS,phone stuck at home screen,no access to bootloader

I rooted my phone. But accidentally deleted my OS. Before flashing with a new ROM, i wiped off the cache/system/Dalvik cache.
When i tried flashing my device, i got some failure. So, i tried to reboot my device.
But, now i am not able to get into bootloader mode. The device is stuck at home screen with HTC logo and is unresponsive. Nor the power button is working to shut it off. I have to wait to get the battery drained.
Also, Vol Dwn+Power is not working to move it to Fastboot mode, so dat i can recover with my TWRP backup.
Also, i have seen that when the device is powered off, i can access the storage using USB, but can't access it when it is powered ON.
I thought of trying flashing RUU but for that i guess i need USB access to device while it is powered ON.
Please suggest me how to resolve this issue.
Thanks in advance

Hi Guys,
I sorted out the issue. Thanks to various information available which i need to put in together to fix.
FIrst of all, the good thing is that i had the TWRP recovery.
I was able to move into Fastboot mode once the device is switched off.
Steps i followed::
1) Place the TWRP backup in the sd card in the proper directory structure.
TWRP -> BACKUPS-> [phone's serial number] -> ROMName
2) Volume up+power button to shut it off.
3) Volume Down+power button to move to Fastboot mode.
4) Select Recovery. You will be moved to TWRP manager.
5) Select Restore there and select the proper recovery folder which u had copied in the sd card.
6) You are done!! BINGO
For those who don't have TWRP backup, they can flash it with a proper ROM available by simply placing the ROM zip in the sd card, wipe the cache from TWRP manager. Select Install from TWRP manager and select the ROM zip and you are done flashing with the new ROM.

Accidentally formatted system partition. Now stuck at bootlogo

While trying to flash a ROM , I formatted the system partition through TWRP and accidentally rebooted the phone. I was running MIUI 7 in the phone previously. I have TWRP backup of system and boot but the phone is stuck at bootlogo and power button volume down combo fires factory mode. I guess I deleted both the recovery and the OS. Phone is getting charged , as the battery indicator is displayed when plugged. Is there anyway to recover my A1?
Sorry if the question is a repeat. Any help would be appreciated.

yo man,
first of all for getting into recovery mode is ; power off your device > wait few seconds > then press power + volume up button, there you go.
then, if youve wiped your device's system partitions via twrp , nothin to worry, just download any rom, put it to your sd card, reboot recovery, wipe everything except sd card, choose downloaded zip to flash, swipe to confirm, once the flashing rom completes reboot your device. :good:

Try to install original CN 20s from here: https://www.mediafire.com/file/3ktjygl15282hr6/X1_X800-CN-FN-BEXCNFN5902012221S-5.9.020S.zip/file
It will erase everithing! also recovery! so you will need to install TWRP again after this. It contains also firmware!
Here is also Cuoco92's tool v2: https://www.mediafire.com/file/6hs8fr17bioxxf9/Le1Pro_CN_CUOCO92_TOOLS_v2.7z/file
For transfering files to phone you can use an OTG cable +USB stick or through adb: https://www.themefoxx.com/2018/06/adb-file-copy-android.html
