[A700] Bricked into "Boot image verified failed"

Unfortunately, I've bricked my Acer Tablet after trying to flash this ROM http://forum.xda-developers.com/showthread.php?t=1994294
The installscript finished the flash successfully, but after reboot, the bootloader only shows the message "Boot image verified failed" No booting and no CWM Recovery is available no more. I've tried several times to get into the fastboot mode with pressing the Power Button and Volume Button with the two knobs, but nothing helps. Neither switching the screenlock switch on and off. I figured out by trying, how to get into APX mode, but I don't know, if and how that could help me, solving my problem :/
Before I've tried to flash the ROM, I had CM10 with the Stock Bootloader in Unlocked Mode and CWM 6.0.2.3 Touch installed, but the Aroma Installer seems to have destroyed the CWM and locked my Bootloader again. Is there any way to unbrick the tablet now? Any help would be appreciated

Just let the battery run dry. Then let it boot up normally without pressing any buttons when the battery runs out by connecting it to your charger. Hope it works!

Thanks for the reply. I tried that, but nothing happens, just the indicator LED on the power button turns on orange. The tablet does not boot on itself, if I connect the charger. I have to press the power button, but this results again in "Boot image verified failed"
Edit: Update. I figured out how to get into fastboot. I read something on google, with switching the screenlock switch on and off. That doesnt worked for me: The thing was, to hold the power button AND the volume button with the two knobs, then the tablet starts, to release the power button and THEN, while still HOLDING the volume button pressed, to switch on and off the screenlock button. Then the bootloader starts into fastboot mode, going into androidsdk and typed in cmd "fastboot oem unlock" solved the problem. The ROM starts and everything is fine

Why you don't write into the mentioned thread? There seems to come the issues from then ask there, sorry can't understand why opening new thread instead asking there.
Also the first time heard sucha thing, I also change the rooms from cm10 to Jacobus, back to stock, on cool one and to cm and back, to test everything and try something out.
Never had issues buy this ways

I don't have the right to post in the proper thread, so I opened up a new one.

In order to install a JB based ROM, you need the JB compatible CWM. The version of CWM you used is apparently for ICS, so I am a little surprised it worked to install CM10. Where did this 6.0.2.3 come from? Use 6.0.1.5 from pawitp. I've used it and swapped/flashed ROMs at least ten times. Never encountered that issue (or any issue). As a matter of fact, I would just run Vorbeth's EasyRoot as it does all the grunt work for you. I've used it twice and it worked flawlessly.

It is just too late... bad luck for me today, I fullbricked the tablet, after performing a restore with CWM 6.0.1.4. Not bootloader, nothing. Just APX Mode.

Hi I had the same issue after flashing from CM10.1 to CoolOne. However I fixed it by unlocking the bootloader => reinstalling recovery => flashing CM 10.1 back.
Did you have any luck recovering from APX?

No, unfortunately not. I gave my tablet 2 weeks ago to the acer repair service and got it back today. The support said, that they have changed the mainboard and flashed the latest android on the tablet, but they did that on guarantee, so I didn't had to pay something ^^ Now it is running Android 4.1.1 Stock ROM from Acer.

Exact same problem
I am having the exact same problem. I am able to boot into recovery mode but then I get the android laying down with with the red triangle, question mark. My bootloader is unlocked but aftrer the update my screen is stucked on the ICONIA TAB startup screen.

[Q] Relay Boot Loop

Chrizuki said:
My Relay wont boot into recovery mode. Whenever I hold the Volume-Up + Home + Power, it turns on then it says on the top left corner a small blue colored message saying "RECOVERY BOOTING..." and then it goes to the "Galaxy S Relay from T-Mobile" screen and then black screen. Nothing happens, it doesnt boot into recovery but it can turn on and function well with the OTA Jelly Bean 4.1.2 update as well as boot into Download mode. I have rooted it before when It was still ICS 4.0.4 and I guess I didnt unroot it correctly.
A couple of days ago, I heard about the Jelly Bean update, which I wanted, so I used Kies to update. I connected my phone while in Download mode and Kies did its thing and my phone was unrooted when it booted up and had Jelly Bean. It worked perfectly, but it couldnt boot into recovery mode. I dont think it's a huge problem to not boot into recovery, but to me, I feel safer having it.
Is there a way to fix this using just Samsung Kies? Is there a way to flash that recovery or something using Odin? If so, where can I find it and how do I do it?
Thanks in advance!

My phone is currently NOT rooted. I attempted to root it when I first got it and almost bricked it so when I got it back to working I just left it. I've had my phone over a year and have recently over the past few months had issues with the charging port and batteries even holding a charge. Bought extended life slim batteries and a charger due to that issue. Then just yesterday I was using facebook on my phone and it randomly rebooted and wouldn't stop boot looping. Only way I've stopped it thus far is to take out the battery.
Any help would be greatly appreciated.

Sounds as though your recovery image might be corrupted. I'd utilize ODIN or heimdall to reflash recovery using download mode and see if that fixes your issue. If you were rooted, and feeling adventurous, you could even do so from within the OS. One more question though: Are you releasing the buttons when you see the samsung boot logo with 'RECOVERY BOOTING....' in the corner? If you do not, then the phone will simply reboot again into the OS. Always let the buttons go once the recovery boot process begins.

Haven't had much of a chance to try due to distractions plus work along with internet issues at home and a friend's house. I will try ODIN. What is heimdall? I've never heard of that.
Yes, each time I try to reboot into recovery I am releasing the buttons as soon as I see the samsung boot logo with 'RECOVERY BOOTING....'
As always Magamo, Thanks for your help

Heimdal is an open source program that implements the ODIN functions. I usually use it as a command line tool, but it does have GUI front ends.

Magamo, I've downloaded Odin 3. 10..6. Not exactly sure what to do now cos I just tried to put my phone into download mode and it boot loops again! So if I can't go into recovery mode or download mode, what can I do? My phone is not rooted and I don't want to root it. Ideally I want to be able to at least copy some of my text messages before rooting it but how can i do anything if I can't get it to go into recovery mode, download mode, or even turn on without boot looping?!
I dont even know what made it randomly one day decide to shut itself off and boot loop.
Any ideas you (or anyone else has) would be very much appreciated!

Sorry i guess i cant help u on this one. But good luck m8!

Completely stock Note 10.1 stuck on splash screen cant access recovery mode.

Hey guys hope this is in the right area. My brother gave me his old galaxy note 10.1 because he said it wasnt working. It boots to the splash screen and stays there. I can access download mode, but cannot access recovery mode. When I try to access recovery mode, one time it the screen will flash twice, and then the third time and every time thereafter(while im holding the power and volume button) it just boots to the splash screen. When the tablet boots the the splash screen, my PC does chime showing a device has been connected, but it never shows in my pc. I have flashed the stock rom with odin that I downloaded, and it passes successfully, and the tablet restarts, but still same problem. I have let it charge overnight, let it sit at the splash screen for hours, removed the battery overnight to drain any charge. tablet it not rooted, or ever been messed with in anyway. I would hope this to be a software issue because that means I can(hopefully) fix it. So, is there any other portion of the memory I can wipe and reinstall? Does odin completely wipe the entire memory when it installs. If its not software Im thinking of just heat treating the whole mobo and having that be the last go at it. Any ideas or recomendations would be helpful.

I would flash a custom recovery via Odin.
Boot to recovery. Format system cache data .Boot to download mode flash stock rom for your model .

If you can find a bootloader flash through Odin.Try sammobile.com.
Nand is the onboard flash ram memory .

ive got one of these, with recovery, it boots to splash screen and stays... i can go through the motions of sideloading a rom via adb, but when the rom is transfered and starts to install, i see a quick error that ive lost root, and the system is read only????
i used the recovery to try and repair root, nada, i then sideload superuser and it says it loaded correctly, but the rom install still fails via sideload...
ideas?

Hhhmmmm your experience shows that maybe it's not software but hardware? Mine is completely stock and has the same symptoms as yours.

Any suggestions on where to find a bootloader?

As my post sammobile .

I've just had this exact same problem with my tablet (gt-n8010) for the second time.
First time it sat in a drawer for 2 months with a flat battery before I took it to a repair center in bicester. They got it working straight away.
This time I thought I'd have a go a sorting it out myself (even though it's been a while since my regular flashing days)
After spending 7hours downloading the stock rom i flashed through odin and retained the boot loop.
I had a hunch that something was being retained in the memory that wasn't being cleared with just reboots so i dissassembled the tab and removed the battery, I then held the power button for about a minute.
I then reconnected all the cables with the battery one being last and powered up the tab.
It then finally proceeded to install the rom package!
So anyone that is stuck in a bootloop for no reason should remove the battery!

Samsung S6 Boot Loop

Hi,
Apologies if this has been asked before, but I've done a relatively thorough search and I can't find a solution to this problem.
I have an S6 (SM-G920F), It was playing up for a few weeks before this, not charging well, and what not, thought it was a cable/hardware issue. Then it stopped working entirely. Initially when it was plugged into the wall it would say it was 91% charged, but if you tried to turn it on it would turn off, and reboot into the charging screen.
I've done quite alot of reading and I've ended up flashing it with Odin (I have a single .md5 file, which i've loaded onto the phone via AP) using the most recent FIrmware UK EE for the SM-G20F. This was successful, however now it only loads the Black screen with white text Samsung S6 powered by android screen and then goes blank and back to the white text screen.
I downloaded an alternative firmware (the one previous version), but this has had the same effect. I've tried to repartition with odin, but this fails.
1.) Is there anyway I can fix this?
2.) If not Is there anyway to remove files whilst in downlod mode?
3.) If I cannot fix it or recover my data, is there anyway to wipe the data securely from my phone so I can sell it for parts?
At present, I can't access recovery mode, only download mode. But whilst Odin communicates with the phone in download mode, I can't seem to access my files from explorer?

1. I would say you'd have to clear cache, immediately after flashing the firmware with Odin, but to do that, you'd have to get to Recovery Mode first...
Why can't you get to it? Does it just start trying to boot nornally? Because if so, it's just a matter of timing it. What I do is... hold power+home+voldown to get to the screen that asks me if I want to get into Download Mode, I press cancel, and immediately start holding power+home+volup until I see the bootsplash screen, and release the power button but keep holding home+volup, and it gets me to Recovery every time, even when I have difficulties such as this.
2. Not that I'm aware of. BUT you could flash TWRP with Odin, and if you then can manage to get to Recovery, you just need to plug your phone into a computer, and your phone will show up in the computer as a device/disk and you can freely remove stuff from it.
If... IF this were to work, I would suggest downloading a stock-based ROM and flashing it. It's far more likely to work properly and bootup without issue than the firmwares you can get, and it's far less much of a headache to do.
3. Nope. There are apps that can wipe data securely (such as Shreddit which does it according to military standards), but it can't be done from Download Mode. There may be some script that could do it in Recovery Mode, but I doubt it.
I mean... technically... you could flash TWRP, go to Recovery, move to your PC all the stuff you want to keep, select the wipe option in TWRP and then transfer randomly generated data from your PC to your phone until it's full - there are many apps that can generate such data. It's not something you could pass off as very very secure, but it should suffice.
I seem to always keep going to trying TWRP - so, you know, give it a shot.

Thanks for your reply! So after flashing it goes straight back into the boot loop. Weirdly if its plugged into my laptop it spend about a second or two on the "Samsung Galaxy S6: Powered by Android" screen before plunging into darkness and shortly after repeating the same message. However if I plug it into the wall it spend over twice as long on that screen before repeating the cycle. It never goes any further.
I've tried your suggestion about perhaps its timing for recovery mode, but even if I go straight from cancelling download mode to trying the power, up and home key it doesn't go to recovery. I've tried a variety of timings both plugged into my laptop and plugged into the wall to no avail. If the phone isn't plugged in, it literally won't do anything whatsoever, won't even hint at turning on.
So Next I tried flashing it with TWRP via Odin and nothings changed, exactly the same bootloop and I still can't get into recovery mode.
I'm starting to think that sadly this phone my be beyond repair! Thanks for your help though, much appreciated.

Hi! I usually run out of my bootloops like this:
try this:
1: go to download mode, and press Power + home + volume —
2: As soon as the screen turns black, continue pressing Power and home, quickly release "volume —" and press "volume +". This will get you into recovery mode.
It always worked for me, so I wish the same for you. Good luck! (And sorry for my bad english)

Hi Vinicius,
Thanks for the suggestion. Unfortunately it didn't work, I even tried flashing it back to a standard ROM from TWRP, but it still didn't do anything, just back to the Samsung logo and the loop continues ever more!

Hi, I have this problem as well.
Originally I had TWRP and root flashed into my phone but for reasons I needed to remove root.
So I followed the Odin route stated here "Mobikin how to remove root from android" (I can't post links but this should be the top result when googling)
However I didn't know if the recovery/boot should have went into AP or BL on the Odin menu and googling didn't give me any answers so I may have tried both....
Right now I tried flashing TWRP and I can't seem to boot into TWRP as well.
I was able to get into recovery mode but clearing data/cache didn't fix it for me.
EDIT: I managed to flash in another stock rom and it boots into the SAMSUNG logo but gets stuck there. I already went into recovery mode to delete data and cache partition but it still doesn't boot.

Same experience. For all those 6 years that I used this device, the wifi was okay until now. It (wifi) is very buggy (turning on and off, and sometimes won't turn on at all) so I restarted the device, then bootloop happens. I flashed the stock rom via odin and clear data and cache. But it is still bootlooping. I think this is the sign that I need to replace my phone IF I couldn't find a fix to this.

Boot looping A8

Hi all,
I have a Samsung A8 that I have been given to me to sort out.
Its currently boot looping at the initial Samsung Logo.
I can get into this recovery mode section shown in attached picture.
The person tells me they went into this mode and pressed Wipe Data/Factory reset as well as Wipe Case Partition.
Since they did this, its been boot looping, it was working perfectly fine before hand.
Im not sure if this has already been rooted or if this is a custom recovery rom?
Not had to deal with rooting or anything for quite some years!
Could anyone help?
Is this rooted, and could I just flash a custom ROM to get it back up and working.
Or is their a stock ROM I can just flash to get this working?
Any help would be really appreciated!
Cheers

so, that screen is the stock recovery where, yes, you can wipe everything that was on the phone, which is actually a good thing. Turn the phone off completely, let it sit for a couple seconds once youre certsin that its completely off. Press and hold both volume buttons and then simultaneously press and hold the power button until it buzzes. When it buzzes, release the power button but continue holding the volume buttons until a screen comes up that asks you to press up to continue or down to reboot. Press volume up, take a pic of that screen and post it up on here. Thats "download mode" aka "Odin mode" From there you can flash the stock firmware and rid yourself of the insidious bootloop. Youll need the firmware from sammobile.com/firmwares tho. Anyways, get to that screen and post the pic up so we can further assist! Have a good day!
