Hello.
I can boot into fastboot or twrp but in 40sec in reboots to normal phone. I cant access the internal memory through mtp even if i unlock my phone. I had it boot to adb mode once and i got the main things off, but i want to do a nandroid backup thru adb twrp it started rebooting.... any suggestions ? The mhl tv adapter didn't work.
SOLVED - I had to boot up recovery without USB cable connected.

Hi guys,
My A510 just turned itself off with no apparent reason. Now I'm experiencing the following, looping :
- It tries to boot,
- freezes on the boot logo (previously "NoThrills", now "Acer"),
- vibrates and reboots.
I can boot in recovery (CWM). When I do, CWM apparently can't access the logs. Here's what I tried :
- wiping everything (data, cache, dalvik)
- restoring Nandroid backup (it was previously a NoThrills JB, now it's back to a stock JB) but I get an error when it tries to restore /data ("Error while restoring /data!").
My computer doesn't detect the tablet when it's plugged in... so I think I can't push or adb anything.
I guess it might be a hardware problem, but does anyone have any idea ? Maybe I could try to diagnose the problem?
Thanks a lot!
You can try to put a full update.zip on your sdcard, and flash it with your recovery
(a custom ROM or a full Acer Stock ROM)
You can also try to format every partitions via fastboot and then, reflash a proper ROM
Hey Shreps,
Thanks for your answer.
- I tried flashing NoThrills' CM10 from the external SD card, it didn't throw any error (although it skipped formatting the boot partition as well as extracting the files to the data partition, I don't know if it's a valuable information or not). Now instead of having the Acer logo during boot, the screen is doing weird stuff and it still won't boot. I can still boot into recovery though.
- I'm not sure how to use fastboot on this device. I get the option to boot into fastboot on my Moto G, but not on my A510. Do I need to flash a more recent CWM to enable it?
Thanks!
Boot in Fastboot via physical button http://forum.xda-developers.com/showthread.php?t=1747802
Thanks!
Volume down + Power on + Rotation switch got me to a black screen with the Acer logo and the following on top :
"Bootloader Version JB-d0ca683 (Unlock Mode)" -> that's normal
"Bootloader VJB-d0ca683(UnlockMode): Starting Fastboot USB download protocol" -> It's stuck there and I'm not sure it completes the operation.
My PC doesn't detect the A510, and "fastboot devices" returns nothing in the terminal.
Any idea?
Thank you!

Should work, try to proper install the Acer drivers & check your USB Cable/port
"fastboot devices" should return a device with its ID
Still no luck after reinstalling the acer drivers... I think some components may be fried at this point?
There's something I'm wondering, it seems I can't mount anything from my pc but I can see files and folders from CWM. Is there any way I could copy everything on the external SD card that's in my A510?
Thanks!

With the Tablet in CWM Recovery you can do a Backup on an SD Card
search for cwm recovery backup on the net
lists you the possibilities.
I had the same Problem, fastboot did not list my device because the mode was for receiving data only. But you can try this:
Tablet off.
Enter the Fastboot Commands in the Command-Line
Then turn your tablet in fastboot-mode.
Good luck.
Hello! I recently dropped my OPO and the screen cracked. The touch also stopped working. But except that, everything looked fine, to me at least. I ordered a new display and replaced it some days ago. Everything went alright, except when I reconnected the antenna cable... It was too short, so I tried to pull a little bit, and then the cable popped off. I'm going to find a solution to this, I'll see if it is possible to replace the antenna cable. Anyway, I put everything else together and started the phone. I was surprised to find out that I ended up in the recovery. I rebooted and I ended up in the recovery AGAIN! So I formatted the internal memory, transferred CM13 + stock Gapps to the phone, installed and booted. I ended up in my recovery, again. I began thinking that the recovery might be corrupt or something like that (TWRP). I tried booting to the bootloader, but ended up in the recovery, once again. These are the different methods I used, trying to reach the bootloader:
- Volume up + power button
- Recovery reboot options
- adb reboot bootloader
All of these methods brought me to the recovery. My goal is to reach the bootloader so fastboot works, and then use this tool to reset my phone. Do you guys have any ideas? Thanks in advance!
What recovery ? Twrp or stock ?
If you are in twrp there is option to boot into bootloader ,then you can flash firmware via fastboot or use otg port,
If you in stock , I think otg port can be used .

This is the problem... I am using TWRP, but even if I use the reboot options, which is booting into bootloader, I will only end up in the recovery anyway...
Any other idea?
There is no OS, so not booting. Use any compatible ROM via otg preferably COS 13 TWRP signed ROM ( no gapps needed ).
Hi guys,
I have a OPO bricked in a very weird way... It's booting straight to TWRP (v3.0.2-0) and nothing else. It is impossible to boot into bootloader (Vol. Up + Power), it still goes to TWRP. And when it is plugged on a computer, it's also booting straight to TWRP...
First a little recap :
- The OPO has (had) an unlocked bootloader and was updated from COS13 to Oxygen OS a while ago.
- The screen was smashed, touch screen not working anymore, and I had it replaced
- Then this problem occured (before screen change, it was booting to Android without a problem)
What I tried :
- Tried to reboot into bootloader, from TWRP via the reboot menu, nope.
- Tried to reboot into bootloader, from TWRP with "adb reboot bootloader", nope.
- Hard Reset from TWRP, nothing.
- Flash latest COS from TWRP (cm-13.1.2-ZNH2KAS3P0-bacon-signed.zip) found here, nothing.
- I wanted to try this last chance unbrick "OnePlus Recovery Tool", but for that the OPO has to be OFF while plugged on a computer, and mine automatically boots on TWRP when plugged , so it's not bricked enough to use it, f***!
Since I can't access the bootlader, I can't do a proper clean/flash
I'm really out of ideas here. I'm starting to think that the problem isn't software but hardware...
Has anyone ever encountered such a brick, or has another idea?
Thanks in advance for your help.
fully shutdown your device and then press the volume up while connecting your phone to pc and see if it can boot into fastboot or not...

Open the back panel of your device and clean it properly with isopropyl alcohol and microfiber cloth.Also clean the power and volume buttons strips.
Reattach it correctly and then try booting into system or fastboot.
Thank you guys for your help.
So, what happened is that the volume buttons connector was dead, and that the volume down signal was "permanent", that is why the device was systematically booting in recovery mode, no matter what I tried.
Replacing it worked just fine
The phone keep bootloopis while I was charging earlier now I cant boot properly,
I can access fastboot mode but I cant access twrp bcs after the twrp logo, i reboot back to os and loop forever.
I have replaced the battery and I still cant boot into it. any ideas?
Update: I flashed twrp while connecting to a charger now it boots, but im using the old battery, will update further
Hello,
my Z3 with LineageOS 17.1 (encrypted) (lineage recovery) worked just fine. unfortunatly some day it just reboots out of the blue and when i entered my sim pin the phone shuts down to a infinite boot loop (sony logo + reboot + sony logo + reboot + ...). USB Debugging isnt enabled. So i can only enter fastboot and flashmode (with flashtool) but ADB isnt working so is the recovery (no usb debugging). On the device are some data i really dont wanna lose (no backup or cloud), so my question is, if there is a way to resuce the data on the phone?
to this point i only found ways to clean reset the phone but nothing to rescue the data. if there is a thread which could help me already send a link so i can delete this one.
thank you for help (and sorry for the bad english)
boot to your twrp recovery you can access your files there
Thank you for the idea but thats one of the Problems, i can't access the recovery because usb debugging is off and adb is unavailable - so booting into recovery dont work in the ways i could find
