[Q] How to recover a bricked A510? Bootloader can't be unlocked! - Acer Iconia A700 and A510

Hi folks,
I have been using Acer A510 for almost 1 year now, and upgraded 7 months ago to the latest JB OTA. I haven't ever rooted it.
Since 2 days, it can't boot suddenly, stuck with the following error message:
Booting failed
Bootloader vJB-d0ca683: Starting Fastboot USB download protocol
Click to expand...
Click to collapse
After a bit of Googling, I tried to unlock the bootloader, as a way to recover the tablet. But that keeps failing as well:
[ [email protected]: /tmp ]# fastboot oem unlock
...
Click to expand...
Click to collapse
At this step, I can see the unlock icon and played with Vol+ and Vol- to quickly select the "Unlock" option, and this is what I get on the tablet:
Unlocking...
Bootloader vJB-d0ca683: Starting Fastboot USB download protocol
Click to expand...
Click to collapse
And on the computer (kind of error messages that are of no help):
...
FAILED (remote: (Unknown error code))
Click to expand...
Click to collapse
So it appears the bootloader can not be unlocked, and I can not even enter the recovery.
I've read somewhere that it may be possible to recover in APX mode.
So is there any way to recover it (either through the bootloader or through APX mode)?
Thanks for your help!

I get exactly the same problem this WE :crying:
I never root/flash/play with recovery or anything else.
Tablet shutdown by itself, then after restart I get trouble to boot :
First the Android said it was unable to start due to encryption : "encryption unsuccessful > need factory reset". Even if I NEVER activate encryption !
I try couple of reboot without suceess, then now it stop on Acer logo and go to fastboot mode at each startup.
Then I have exactly same trouble : impossible to unlock bootloader using fastboot.
No way to flash something.
Need help !

If fastboot is available, you can try to boot CWM Recovery or TWRP recovery
fastboot -i 0x0502 boot C:\....\cwm-recovery.img
From there you can try a factory reset

It doesn't work as the bootloader is still locked !
Code:
FAILED (remote: bootloader is locked.)
And it's impossible to unlock bootloader as describe in the post.
Any other idea ?

You can try to download the full ROM from acer Web Site (GEN1 or CUS1 depending on what you had before)
rename it to update.zip and put it on your sdcard
Reboot your tablet in recovery if you can to flash it, or in bootloader (don't remember if the Acer bootloader can flash an update.zip)

Its 2015 now but i will post this anyway..
Try this
1st, Boot into recovery:
- Press [vol-] + [power]
- Once the tablet vibrated, let go [power] and keep [vol-].
- Now the tablet vibrates a second time, let go [vol-] and press [vol+] quick
- Once the text that appears on the screen ("loading recovery kernel image"), let go [vol+].
2nd, choose "Wipe data cache & factory reset" via volume rocker and power button to select it.
3rd, choose "reboot"
I solved mine using that steps, hopefully it will solve yours.

Thank you very much!!! It worked for me!

So I have tried the above listed technique and it brings up the clockwork mod screen but does not go past it. Any more suggestions?
Thanks.

Hello everyone, it may be late for you but i found a solution for a bricked A510 :
for my part i only had access to bootloader unlock and fastboot, but it didn't communicate with my laptop
So i found a software called DriverHub and launched it with my A510 connected to my laptop
It found the right driver for it (was not the of from Acer or any universal ADB driver) and i could use the fastboot mode to unlock OEM and flash TWRP, and now i have Cyanogen running on my tab who came back from dead
Here's a link to the software : www drvhub net
Have a nice day

Bricked (?) ASUS Transformer Infinity TF700T

Hi there,
I need your help urgently.
I received a brand new TF700T and did make it work to support root.
I also did unlock the bootrom protection.
When I tried to install a custom ROM manager (Clockwork Mod) image from:here
The device didn't want to start any more - showing message:
The Device ist Unlocked.
Android cardhu-user bootloader <2.10 e> released by "TW_epad-9.4.5.22-20120615" A03
Checking for android ota recovery
Booting recovery kernel image
But nothing happens anymore (
I can wait for the battery to run empty in this mode.
There' no chance to boot from Micro SD.
The only thing what works at the moment is to connect the device via APX drivers.
I tried to communicate with device via NVFLASH tool
But when trying this - I get the message:
Nvflash started
Unknown Device found
Does any one have an idea where to find appropriate drivers for Nvflash?
Or the parameters to match TF700T?
Thanks in advance!
if you are able to access APX then you still have hope, first of all you need to push custom recovery like TWRP via fastboot mode and then install custom ROM. Most likelly you were to lazy to read a lot information on this forum how to install stuff properlly.
EDIT: if Tf700t has pin hole you should turn it off despite waiting for it to discharge...

I did already read a lot - for hours and nights.
But my main problem is: UNKNOWN DEVICE
What does TWRP mean? How do I get fastboot to work?
I'm even not allowed to enter recovery mode.
The device is just recognized as an APX -device...
I can't push or download any custom ROM since I can't communicate with the device in both directions...
For those who messed up really bad and can't boot but are unlocked.
EDIT: I didn't see that you are not unlocked. then you should Power on + volume down, wait, see two icons select wipe, pray to god it helped or not. And if it doesn't boot and you are not unlocked last thing to do is RMA.
You are not allowed to enter recovery because you have stock one with droid dead and red triangle I guess.This is TWRP site and all instructions are here TWRP - Team Win Recovery Project is alternative to ClockworkMod Recovery but better. to get to fast boot turn on your tab holding power on + volume down and then do nothing while it asks to pres up. if you are unlocked you will see 3 icons select usb drive icon. FASTBOOT mode. now follow instructions from TWRP site. after that youl need custom rom zip. if recovery instaled successfuly and you can get into it you'll need to put custom ro into microSD or if you can into internal storage. if you can't conect to pc via cable and start cmd if Windows or terminal if Linux or mac. type
Code:
adb shell
mount /dev/block/mmcblk1p1 /data/media
you will be able to access microSD via recovery (unless it is different than Prime tf201 you will need different command, but give it a try)

Thanks for advise - BUT
I have no choice like selecting Fastboot or USB etc. with volume buttons.
These options unfortunately do not come up anymore.
My device is definetly unlocked. It shows up "Device unlocked" when trying to boot normally.
When trying to go to recovery, with Volume - hold, the device tries to launch to recovery but hangs in status:
Device is Unlocked
Android cardhu-user bootloader (2.10 e) released by "TW_epad-9.4.5.22-20120615" A03

I have NO option to go to fastboot! Only way will be APX but nvflas always tell me unknown device.
So I was looking for any other version of nvflash.
In other forum I did find hint for nvflash ICS but didn't find right version yet.
If I only could get communication via APX worked to my device, then I could send data via nvflash and APX...
I assume you can't even go to rom as it bootloops on EEE pad screen not on rom splash screen
1. Did you try Wipe option in (power + volume down, wait 5 sec.)? [it is esential in all situations of trying to recover]
2.ammm... when you enter "adb devices" in your cmd on PC doesn't it show anything (do it while your tablet is on and hangs anywhere, just make sure it is on)? list is empty? if not it shows your device with some random letters and numbers.
Try manually setting your pc. Download android SDK and all packages for Android 4.x then in Device Manager (Control panel) find your Tablet and update your driver to Android ADB interface (you can experiment, till your device is shown correctly via adb devices command).
But first of all make sure you do or did first step. it is common issue among Prime users so maybe it can help you.

I would like to exchange email-adresses to enhance communication.
You could also send email to [email protected]
I did try with button combination (power & + button) as well, but device did not wipe.
For now - I'm about to update Android SDK )
Hopefully this works to recognize my TF700T...
If you manage to unbrick please post the information back here it may be helpful to others.

How did you get your TF700 unlocked? Asus hasn't posted an unlock tool for it yet that I could find.
Asus devices have the same unlock tool

Unlock + Root was never a problem.
I managed it to unlock the device using the TF300T tool / link.
Boot loop was big problem.
I did raise RMA in the meantime. New device is on the way.
Thanks to all repliers.
I will keep off doing this again / wait until xda-experts will provide a working way to CWM TF700T.
My Transformer Infinity isn't bricked, I just can't get it to boot into recovery. (I'm unlocked and rooted, but no custom ROM.) I have tried both CWM and TWRP 2.2.0 with GooManager. The tablet just won't boot into recovery mode. I can hold the Down Volume key and Power button to have the initial boot up menu display. When I press the Up Volume button to boot into recovery mode, it just hangs like the OP talks about. I then have to hold the power button for about five or so seconds to get it to power down again. I can turn it back on and it will boot normally.
I thought maybe something was messed up because I installed busybox, or hacked the Flash Player to work in desktop mode, or tweaked the build.prop file or something. I've put the build.prop file back to default, and removed the busybox apps, but that hasn't resolved the problem. I've tried re-running the unlock tool, but it fails halfway through. I'm not sure if that's normal or not after you've run it once, or an indication of something messed up.
Any suggestions on what else to try or look at are appreciated.

UPDATE: I finally got TWRP 2.2.2.0 to work using the following option from the Instruction Page (http teamw.in/project/twrp2/105):
Download - ADB / Terminal method:
Download the above file. Save it to the root of your /sdcard directly (internal memory only) and rename it to twrp.blob
Launch terminal emulator or connect to your computer and open an adb shell, then type the following:
su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
Then reboot to complete installation.

Trying to flash the new CWM recovery, too. Mine gets stuck in the bootloader menu (where you have to choose between Wipe, fastboot mode, and cold startup). Every time I select fastboot it says "starting fastboot usb protocol" and just hangs there.

That is what it says when you are in fastboot mode, the rest of the job you do with a computer. Also we have had major issues with cwm on the Prime, I would recommend TWRP!

[Q] Help Revive my Xoom

Hey All,
My Dad's Xoom died over the weekend - 13months after purchase so is not covered by the warranty. He was browsing a site, it came up with a "Internet is not responding - do you want to continue to wait" message and he clicked Wait - after a second the tablet knocked off. It will not come on by pressing Power and only turns on by pressing Power and Vol +
It gets past the Motorolo logo screen and the device starts the boot animation, about 20 seconds into this it freezes and reboots - this continues in a loop. It's been GEDified and was running the last OTA update 4.1.2 - no root etc.
I can get into the stock recovery and performed a factory reset - but the same thing happens. I've also tried Update From USB with an OTG cable but the screen just shows Choose a package to install and under it has /sdcard but nothing else. I have a dummy zip on both the Flash disk and SD card so it's not reading either.
I've also tried to perform update via ADB - when I select it and connect to a PC (Win 7 32bit) it tries to install drivers but I see In Computer Management that it shows under Unknown. ADB Devices returns List of devices message but nothing under it.
I've also selected the fastboot command at boot, tried fastboot devices and the command does see the Xoom.
So my questions
1) Anyone seen anything like this issue before and know how to fix it?
2) Is it best to try to reinstall the ROM? If so, how do you suggest I can see it with ADB?
3) As I have Fastboot command, could I try to install CWM and see if that sees a ZIP on the sdcard - so I can install a new ROM.
Any help much appreciated :good:
so...I've just done a fastboot oem unlock
and then tried to flash the CWM recovery using the fastboot commands - no errors, press reboot and go into Recovery but still getting Android system recovery 3e :crying:

So just to add to this, I found the stock recovery.img, boot.img, userdata.img and system.img and used the fastboot commands to send all to the motorola - all succeeded without error....still the same problem though.
I installed RSD lite and tried a few SBF files but I'm getting an INI error - off to google possible solutions to that now

Nexus 5 Bootloop + No Power Button + Locked Bootloader + NO ADB -- Recover Data

Hey guys, so I have this dilemma on my hands. One of my friends has a Nexus 5 that has a power button issue. It seemed like a stuck power button, because even cleaning it did not solve the issue. So I removed the power button, and it finally turned on. However, it's now stuck in a Google logo bootloop.
The Objective:
To recover all data on the device. This is a must.
The Obstacles:
- No physical power button, but I can place a pair of tweezers on the terminals on the board to simulate a power button press.
- Bootloader is locked (I can unlock it, but that erases all data on the phone).
- Cannot enter proper stock recovery (I get a "no command" error when I do; I've tried all button combinations afterwards, including the ones from HERE, but to no avail).
- USB debugging was not enabled on the phone when booting normally, so even though the phone is recognized by my PC, I cannot do anything using ADB.
- Fastboot mode is the only successful mode I can reach on the phone.
The Final Question:
Does anyone know how I can successfully recover all the data on the phone using ADB or any other method, having the above obstacles?
Thanks in advance.
If you can reach fastboot without any problem, you can try to boot a custom recovery image using the following command : fastboot boot recovery yourcustomrecovery.img
(if you dont have a custom recovery, you need to flash one with : fastboot flash recovery yourcustomrecovery.img)
It will boot in recovery mode and, I hope, allow you to have an adb access and recover your data.
edit : since your bootloader is locked, i guess this won't work.

I bit of a trick. Try 'fastboot flash boot recovery.img' but instead of kernel flash twrp. After flash do a 'fastboot reboot'. It will boot recovery. Via twrp the pc will recognize phone as a media storage. You will not erase any data

Thanks for the response, but the bootloader has to be unlocked for that to work, and while I can do that, it will wipe the data I need.

PLEASE HELP! Bricked Honor 8

I am unable to get to the fastboot.
STEPS I did before brick:
1. unlocked OEM via official way
2. flashed TWRP
3. after that my phone was reset however most of the apps was missing, I was trying to do factory reset once again but it failed with the message "Data partition was heavily damaged"
4. I re-locked EOM
5. brick as mentioned above
Please help, I have the phone only two weeks and I have no idea how to fix this without fastboot.
Thank you.

Sounds like you flashed the 3030 version of TWRP. Download the 3020 version and put it in your fastboot folder. Plug in the USB to PC
Hold power and volume up untill the phone reboots. While it's still off immediately change to power and volume down and hold till it goes into fastboot (bootloader)
Now fastboot flash recovery TWRP.img
With the 3020 version.
Unplug the USB and hold power and volume up until it says the phone is booting.. let go and TWRP will load.
Go to Wipe / format data / type yes
Reboot to system and your all set

So I've tried that but the phone is still booting to recovery (flashing TWRP logo) no matter what.
Basically the phone is always on now because if hold the power button (or any other combination) for a few second it will just reboot back.
I have an access only to ADB, but I am not able to boot to bootloader at all, it seems the bootloader is damaged somehow.
Also that warning about unlocked OEM doesn't have that text saying "hold volume up to boot to recovery" etc. like before brick.
Hi there,
Try using the Huawei Multi Tool with the Unbrick option : https://forum.xda-developers.com/honor-8/development/tool-huawei-multi-tool-team-mt-t3523923
Speaking from experience, this little fellow helped me recover my phone when I bricked it ON DAY ONE after failed root attempt... (Derp)

So I've tried that but the phone is still booting to recovery (flashing TWRP logo) no matter what.
Basically the phone is always on now because if hold the power button (or any other combination) for a few second it will just reboot back.
I have an access only to ADB, but I am not able to boot to bootloader at all, it seems the bootloader is damaged somehow.
Also that warning about unlocked OEM doesn't have that text saying "hold volume up to boot to recovery" etc. like before brick.

Booting to the bootloader is just a timing issue
Phone must be hooked to PC with USB
And volume up and power till it goes black
Then immediately volume down and power and Hold untill the bootloader loads
Keep trying until you get it

I appreciate your help but I've tried it multiple times always with the same result.
I also can use "adb reboot bootloader", but it will reboot again to stuck recovery.

Hi there,
Try using the Huawei Multi Tool with the Unbrick option : https://forum.xda-developers.com/honor-8/development/tool-huawei-multi-tool-team-mt-t3523923
Speaking from experience, this little fellow helped me recover my phone when I bricked it ON DAY ONE after failed root attempt... (Derp)

I've tried that, but I am still stuck as that tool is using fastboot as every other tool to flash .img files.
Thank you for the tip though.
Plug phone into computer with USB, then hold down power + volume down until it eventually boots into bootloader. I had the same scenario as you and that's how I got into the bootloader. You can flash either a good TWRP or the stock recovery, either one will work.

Flashing TWRP without first flashing a vbmeta image with verity disabled rendered my Galaxy Note10 exynos unable to boot

Newbie here. Tried to download TWRP onto unrooted device (Galaxy Note10 Exynos d1) with Odin and now my phone is stuck on "downloading" screen. When I try to cancel (restart phone) it goes to the startup/booting screen for less than a second and then jumps back to "downloading". It says this at the top left corner of the screen:
recovery: Error validating footer (6) CUSTOM RECOVERY VBMETA N970F XXU1 ASG0. 24967245R
I am able to get into the custom OS installation screen (don't know what it's actually called but second picture) by letting the battery drain so that the phone turns off and then holding volume up + volume down key and plugging the phone into my laptop with USB.
The bootloader is unlocked. I went to https://twrp.me/samsung/samsunggalaxynote10.html and even there it says "Flashing TWRP without first flashing a vbmeta image with verity disabled will render your device unable to boot." Does anyone know how to fix this? Thanks in advance.

Go first to the unlocking menu to check if your device is really unlocked, long press volume up, and see which the menu says.
If it is unlocked, then flash the vbmeta file provided, then try to boot to recovery and perform a factory reset.

Bootloader is unlocked and I've flashed the vbmeta file but now my phone is stuck on the startup screen and I can't seem to boot into recovery. Why?

Maybe you missed some essential part of the process, by unlocking your device through the Download menu option your data has to be erased, it's recommendable after to unlock the bootloader, to reboot again to system and check once the UBS debugging and OEM unlock options if they remain fine, from there you should reboot to download mode again, uncheck the Auto-reboot option within Odin, flash the vbmeta.tar and then flash the TWRP, if all till here goes well you should reboot manually to TWRP by powering off completely, pressing the three buttons, and just now, pressing the volume up + PWR key buttons till your device boots to TWRP.

The screenshots you uploaded some months ago, are the download screen, you, successfully did boot to, download mode doesn't have a useful menu, it's just a mode, so you can flash some things, using Odin. To boot to, use the same way you did it previously, usually, doing it manually, or if you are rooted, you can use other ways too.
