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.
Hey guys!
So, i was trying to install CM13 unofficial version, and wiped the system and internal storage using TWRP recovery. I was supposed to install the rom from a zip file i had placed in the external memory card. What i did, was, i rebooted the phone by mistake, after wiping it from the recovery without installing the ROM and now the phone is caught in a bootloop. I know i am an idiot to do that. I tried removing the battery and reboot it in recovery mode using the key combination with no luck. It just starts the boot loop. I tried using fastboot and adb from pc to push files into the internal memory, but my device is not getting detected on the adb anymore (maybe the usb debugging is disabled now?).
What i guess is stopping TWRP recovery from showing up is the lack of twrp/themes folder in the internal memory since i wiped it. But there might be some other cause that i am unaware of. What do i do now? Any help will be greatly appreciated!
Hey! I'm having the same problem with my yu yureka.. Can anyone help me please!

Hi! I'm having the same problem with this post... Does anyone knows the solution of this problem. I'd be really glad if anyone could help me with this..please!
Hey are you able to boot into fastboot mode? If you can....
Prerequisites –
1. Make sure that you have 70-80% battery on your phone.
2. You need a PC and a USB cable to connect your phone to the PC.
3. Flashing the factory firmware will wipe all the data present in the internal memory. So, make a backup of that if you can.
4.Install all the necessary Device drivers.
DOWNLOADS -
1. Download the flash tools from here . http://www.mediafire.com/download/87gfz7mdch188an/Flashtools_For_Yu_Yureka.zip
2. Download the factory firmware from Here (cm 12.1) . http://builds.cyngn.com/factory/tomato/cm-12.1-YOG4PAS3JM-tomato-signed-fastboot.zip
Steps To Flash Factory Firmware –
1. Extract the flashtools zip in a new folder on the desktop.
2. Extract the factory firmware zip in the same folder and make sure that all of the flashtools files are also present.
3. Now, power off your phone. If you are stuck in a bootloop, then pull out the battery and reinsert it. (Do not switch on the phone.)
4. While pressing the Volume Up key, connect your phone to the PC with the help of a USB cable.
5. You should now see the fastboot logo on your device. If you did, leave the Volume Up key. (If you do not see the logo, retry the process.)
6. Now go to the folder where you extracted the flash tools and factory firmware and run the flash-all.bat by double clicking on it.
7. A command window will open and the flashing procedure will start. (Make sure that your device does not disconnect from your PC during the procedure.)
8. The command window will automatically close once the procedure is completed.
9. Disconnect your device and boot it up by pressing the Power button. (Since this is first boot after flashing the firmware, it may take upto 5 minutes.)
Done you should be back on cm 12.1

I flashed the factory image via YGDP tool as well as fastboot. But it boots upto a point and then goes in bootloop. Also if i wipe data/cache still it makes no difference. Also unlocked bootloader and twrp also don't load up. Again goes in bootloop.

Hi, I flashed my Yu Yureka AO5512 Yesterday and entered into recovery mode and selected the wipe userdata option. When it was doing the process after 20min the process stopped all together and My phone does not start at all now. If i press any button there is no response at all. Looks like phones OS and everything is wiped out. How do i go about from here?

Sorry to hear that anyway,
By stock lolipop you mean you had the yureka plus with Volte From factory right!!...if so the twrp might have been for the yureka plus with the cm bootloader which got replaced in the new Devcice
I am facing the same problem and in my case I dont think its an battery issue...I was happily using the CM 13.0 Snapshot Rom since a long time...but today morning when I did a soft reset by going into the settings in my yureka...the phone has gone in bootloop...and nothing is working...using fastboot I even flashed the twrp again and also flashed the CM 12.0 Stock firmware..but nothing is working...after the YU logo it restarts....please help...
I am also facing problem maybe worst
I dont know what wrong I am doing but I am getting "FAILED (remote: unknown command)".
Few info:
1. I get my device ID when I do "fastboot devices" but nothing on fastboot -i 0x1ebf oem device-info".
2. Also for my YU5510A fastboot screen doesnt say' "fastboot" it says "Information do not unplug the cable - Secure Phone".
3. I have red light on, phones keeps rebooting 4-5 times than red light goes off and charging stops.

Ignore that and use other fastboot commands and go ahead, as your device is being detected in fastboot mode.

But when I am executing other fastboot commands it halts the process between with error "FAILED (remote: unknown command)".
I have read about this error and people suggested that I need to get into "Download mode" not "fastboot/bootload". To get into "download" mode I tried pressing "VoulumeDown+Power+Home", but nothing happened, it simply restarted the phone.
Please advise.

Hi everyone,
I'm sorry if I post this question in a wrong section but there is no thread for my device on xda.
It seems like I ruined the recovery mode of my Android tablet. It's a HP Pro Slate 12 tablet with Android 5.1.1 on it. It's rooted. I wanted to install CWM Recovery to backup everything, but my device wasn't listed as a supported device. My friend told me I can install the LG G3 recovery instead because it's compatible. I installed that. Since then recovery mode completely disappeared. The device still boots in normal mode and works, but I cannot boot into recovery mode anymore. I really need it because the device boots normally but sometimes acting strange since I rooted it. I'd like to try unrooting it by going into recovery mode or doing a factory reset, but both options disappeared.
Here's what I've tried:
- I Googled this problem very thoroughly, but didn't find any help aside from "hold down 2 buttons to go into recovery mode" type of answers.
- I tried holding down volume up+power buttons while turning it on, but didn't work.
- Tried holding down volume down+power. Nope.
- Tried rebooting inside Android into recovery mode with Quick boot app. It rebooted my device but again it went into normal mode instead.
- Tried to reboot into recovery mode with ADP and FastBoot in Windows. ADB recognized my device (listed the serial number), Fastboot didn't recognize my device. So I tried to reboot into recovery with ADB. Same stuff happened. The device rebooted into normal mode.
- Tried to do a factory reset. DIDN'T work! Rebooted into normal mode once more. The factory reset hasn't deleted anything.
- I have the latest available update.zip from the official website for my device, but without recovery mode I cannot install it.
Any ideas? Did I really lose the possibility of recovery forever with a single click?

Hello did you find a solution to your problem ?
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
I was trying to flash twrp using an app called flashify but I ended in bootloop
I have bll-l21 unlocked rooted and I can enter fastboot mode but my pc doesn't detect it and usb debugging is disabled
Factory reset or dload method at this point... if you would had USB debugging active you could manually flash TWRP by adb and fix things, but in that state there isn't much possible to do
Solved , I only deleted the recovery and the os was working and my phone was trying to enter the recovery while there is nothing I forced it to power off then it rebooted automatically and powered it off again and on while pressing volume up and down and magically booted to os again thank God

YEs that is recovery issue only. Once you boot to system it will boot.
Why not try the traditional way via fast boot. there is a user friendly guide in my signature, try it.
Question
How did you deleted the recovery with the help of a tool or cmd?
