[Q] soft-bricked? my acer iconia a500 please help!

Ok, I seem to be making things worse and worse, so I've come here to beg for help.
TLDR:
my acer iconia a500 was running skrilax_CZ's bootloader V8, I screwed it up (I think) by trying to install ClockworkRecovery.
I was still able to boot into Tegraowners_JB-MR1_ROM_v11t4
I messed a BUNCH more stuff up. a bunch!
Now, I can still see the internal and external SD but when i try to use blackthund3r's tools to root/recovery/custom-mod
it gets stuck when trying to enter APX mode. "No APX devices detected"
I do have the CPUID and the SBK
Longer explanation and details:
I installed Acer's USB drivers: USB_Acer_1.06.1500_A30H_A
I rooted the device using: ICS_rooting_A10x_A5xx --> runit-win.bat
I used blackthund3r's tools: A500APXFlash.exe and A500Manager.exe
I installed a custom bootloader rom: V8-Thor_1.7.3_recovery.a500apx
I installed Tegraowners_JB-MR1_ROM_v11t4 and gapps-jb-20130301-a500-v2
I was happy as a clam for 2 days playing with my fancy tablet.
I installed Superuser App
I made a nandroid backup at least once from the v8 bootloader.
I made a batch Titanium backup
I then tried installing clockwork recovery mod, and I think that's when i screwed myself.
Suddenly the power on + down_volume switch just led to a screen that said "Skrillax_CZ's bootloader V8"
"Booting recovery kernel image" and then it would hang there forever.
I could still boot into Tegraowners_JB-MR1_ROM_v11t4 so I tried to run a restore from Titanium Backup,
it froze halfway through with the message "superuser access denied"
I rebooted, and suddenly most of the widgets/apps are gone, and the back/home/and application navigation
button that are usually on the bottom left corner are also gone!
then I did a bunch of crazy/desperate stuff with blackthund3r's tools, (something involving trebuchet?)
and I finally blacked out amidst tears and despair around 5 am this morning.
so
now, when I use A500APXFlash.exe and A500Manager.exe it tries to put the tablet into APX mode, and the
tablet goes to a blackscreen, with a white LED on the power button, but I get the error "No APX devices detected"
I also tried inserting a paper clip then turning the power on, same result.
I do have the CPUID and the SBK
Please help if you can, and please dumb down your explanations if possible, this is my first tablet and
i'm totally new to android, etc.
Thanks for your time
-Joel
couple more details, it boots to the point where you swipe to unlock it, but when i do, i get a popup that says Trebuchet has stopped,
and when i click ok, it just comes back infinitum
oh, and when i use A500 Manager.exe it says that it's connected and usb debugging is ON, but I have no way of getting into the settings
to confirm that?
I don't want to come across as lazy, I literally have 8 tabs open from xda-developers and 3 from tegraowners. I also just tried afterotav_109 but that didn't do anything.
I found
the following files in
Computer\Acer Iconia Tab A500\Internal Storage\0\.AcerRecoveryInstaller
(see attached picture)
I'm guessing I can't rename recovery.old to recovery, or something easy like that?

small update, installed android SDK and adb shell
when I launch adb shell I can see the various directories on the tablet internal and external SD. I'm in the process of scouring the forums for info about how to use the adb tool to fix my problem, am I even on the right track?
thanks for any feedback y'all can provide
-Joel

TBH installing T/O's rom you should really be asking on their forum - their roms are a little different to the ones on xda - like, you don't need the v8 unlocked bootloader you can run it on HC or ICS Bootloaders.
android adb/usb drivers?? you dont mention them are they on your PC?
I then tried installing clockwork recovery mod

Didnt you already have cwm 1.7.3?
How did you try to install it? and yeh this is probably where you went wrong.
You must install custom recoverys using either fastboot or an appropriate flashable zip

For future reference what you should have done here is run the 1.7.3.apx with apxflash tool.
I could still boot into Tegraowners_JB-MR1_ROM_v11t4 so I tried to run a restore from Titanium Backup,

If thats the error it means the drivers are screwed up. Completely uninstall the acer drivers, reboot and reinstall. But w8 theres more....
Make sure you got the adb/fastboot drivers here
Please help if you can, and please dumb down your explanations if possible, this is my first tablet and

Acer recovery installer? OK so I assume you used that to try and flash a recovery? This app works best on HC Bootloader - the only way to use it with ICS is IF you already have the v8.
Also, you must make sure you run the correct recovery for whatever version of ROM you are wanting to flash. So check the OP of your chosen rom for which recovery you need. Most of the ics/jb custom roms here on xda work with cwm 1.7.3, TWRP or public recovery. BUT these wont work on HC
I'm guessing I can't rename recovery.old to recovery, or something easy like that?

You can use an appropriate recovery.img and flash via fastboot
-------------------------------------------------------------------------------------------
OK so lhow do we get you fixed???
You need to do a complete FORMAT (factory data reset) of your system to get it back to a state where you can use the tools.
Install the adb drivers first!
Lets see if fastboot mode is available.
As long as you see skrilax_cz v8 bootloader on your screen connect yr micro usb cable - power down and boot up holding VOLUME UP button...you should see the fastboot menu now follow the instructions here on using the fastboot commands to WIPE userdata and cache
THEN if you have the correct recovery.img you can flash this too (see that post) if not run the apxflash tool again using cwm 1,7,3.apx file.
Now, once you have run it BOOT DIRECTLY to recovery and flash your rom. (Doesnt matter which one as long as its ICS or JB...)
This is important...if you try and boot yr tabs OS, you'll get either booting primary kernel error or be stuck on the acer logo -
IF fastboot is not available then run the apxflash tool to install recovery instead then using that same post it shows you how to do a full format wipe, with cwm.
I hope this isnt too over the top for you...I've tried to explain things so you can understand a bit better - but I may have to 'dumb' things down a bit more, let me know
good luck with it
dibb

thank you so much for replying, i'll get right on this
Dibb thank you very much, as soon as I get back I'm going to go through your directions step by step.
I really appreciate your help, and I'll post an update later tonight.

in fastboot, please advise

DIBB IS TEH AWSEOMEMEMEST!!!!!!!
fastoot mode worked!
one thing that threw me off is that I had to figure out that I needed to type
Code:
fastboot.exe flash [B]recovery[/B] recovery_thor17_403.img
the guide here
doesn't specify which partition to use so I got an error message until I guesstimated I wanted the boot partition.
Anyway, once you fixed my bootloader, I restored the full system from a backup I had made on the first of the month.
thank you thank you for your awesome help!
now I can break it again and again!
made a minor edit, changed boot --> recovery in the "code" section above

Glad u got it
Not sure why you had to use fastboot.exe as the command tho? but as long as it worked and you're up and running, that's the main thing!
happy flashing

Help really need here, big issues

Hello to everybody, so i was thinking my nakasi was really dead this time, the last thing i did was flashing a 5.1.1 rom next when i rebooted got stuck on lolipop boot loop so i restarted the tablet
manually to access the recovery, and to my awe, i couldn't no more access the recovery ! (latest twrp) tried again and again nothing, no recovery no bootloader, can't start the OS
always stuck on google logo with the options above, start, bootloader, recovery etc, today i realized i could access the bootloader and fastboot mode (ADB recognize my device when i type fastboot devices)
so i tried flashing stock image and stuff with no luck, tried many stock roms, tried wug's toolkit and the flash all.bat still no luck, i get all kind of error messages here is a screenshot, help is really appreciated if there is anything i can do to save it :
View attachment 3305126

the problem seems to be that i can't write the things i send to the tablet via ADB, tried the NVflash recovery today and got :

Have you tried not imputing the full file address as you have the emulator already running from that location.
So recovery command would be.
Fastboot flash recovery "name of recovery Img file here"
Just make sure that the image file is in the platform-tools folder.
Probably not your issue but its going to save you some typing.
Good luck

Thank you for the tip I'll certainly use it, but i don't think it is the culprit since as you can see in the screenshots
the files get sent successfully but cannot be written, my bootloader is unlocked by the way

Did you try the latest factory image? I noticed you are flashing a very old bootloader, possibly the first one? 4.23 is the current version.
Where is flatline_grouper.img coming from? I've never seen that.

Hello kind sir, of course at first i tried the 5.1.1 full factory image with the NRT toolkit and got the same writing errors next i tried many bootloaders
(one of them found it here as a 100% working bootloader) the Flatline is the recovery of the NVflash tool where you can access it to unbrick full bricked N7s
if you got blobs.bin of your N7 backed up (clearly not my case)
the flashing writing error i get it with everything i try to flash, recoverys bootloader system etc
when i send them with the flash all command they got sent to the tablet okay, but when writing i get the errors
i don't know but there is a small informations if that can help, before it broke my system was in EXT4 and all the rest in F2FS

It's entirely possible your memory has failed. I'm reading more and more people running into corrupted memory issues.
You can get a replacement motherboard cheap on eBay if nothing else works.

I'm still hoping for a software solution since my fastboot works fine, I'll let the motherboard solution my last i guess

Hello some news about the still staggering situations : when the tablet is off and i put the charger i get the battery refiling animation ! so that mean the bootloader isn't broken
and i still can access fastboot mode, even when i push a bootloader i get a signature match message, but the problem is still that the things i push can't be written as i'm still getting a :
FAILED <Remote: <FileWriteFailed>> changed usb cables, changed ports, the last time the tablet was working i had the system on EXT4 and the rest on F2FS, maybe if i can convert everything to EXT4 ?

Bricked while trying to install Full Android rom.. Now Boot loop into twrp. Pls help.

Well,
basically subject says all.
I tried to install zulu99 Full android rom 2.1.
basically 'fastboot flash system system.img worked' but 'fastboot -w' failed ('no space left' error).
So I rebooted hoping to reflash a nandroid backup but now the box keeps on rebooting into twrp trying to wipe cache and data but failing. after a while it stops and black screen appears.
I attach the screen it presents when reboots.
Please tell me I didn't trash 220 euros.
Thanks.

Theres a hardware method to boot into the bootloader, this i think you can test, just to see if you can at least get into bootloader.....nothing more
Details in the official nvidia link
http://nv-tegra.nvidia.com/gitweb/?...ob_plain;f=README_SHIELD;hb=rel-22r18-partner
There's a thread here on the "questions" thread with users reporting that the timing of the hardware method can be a pain in the you know where.............might be worth looking into that thread for their experiences in booting the bootloader using the hardware method
Disclaimer:If your brave enough to risk a brick, read on
I suspect this might be the 2.1 stock/twrp issue........current twrp, or current stock dont play nice
Its a good sign that SOMETHINGS loading, rather then NOTHING booting, but dont know if theirs a solution
My analysis of the situation, of what little i know, the -w (wipe) command was expecting a stock recovery but instead got twrp, which is why your in this situation.........maybe, i stress maybe, if you could reflash stock again, you might be able to boot into android stock again and try full android again, leaving out twrp, until a twrp fix is found
Edit
Saying that, if the bootloader is, as i suspect, now using twrp to flash things, then you might be boned....... im no expert on bootloaders, stock "recoveries" and how they work, so i might be wrong on that
Reports around here say that 1.3 stock firmware is the recommended back to stock firmware, apparently, flashing any other firmware versions, bring their own issues.............
From 1.3 stock, use nvidias official OTA to upgrade from 1.3 stock, to 2.1 stock, then try 2.1 full android again...........note, i dont think you can skip firmwares i.e. you have to upgrade to 1.4, then to 2.0, then to 2.1, alot of downloading.......the OTA does'nt give you any other choice
Before doing anything that ive suggested, wait till someone with more experience to come along........i dont want to be responsible for you fully bricking your shield..........just wanna give you an idea of what i think has happened
If worse comes to worse, if you have warrenty, get a replacement
Gd luck........remember, this is an analysis of your predicament of what i THINK might of happened, and what steps, i likely might of entertained.......after looking into it more thouroughly, knowing that i could get a replacement if it went downhill.........so your mileage might vary

Crappy grammer, further musings, clarifications

I had something similar about... shield goes booting in recovery and trying delete some cache and keeps repeat and repeat
Hardware boot in fastboot / bootloader mode
Accessing Bootloader via Hardware
Unplug power from the Shield Android TV. *
Wait a few seconds.
Hold down the power button.
Plug in power
Count to three
Release the power button
You should see the bootloader screen.
If you hold it down too long or not long enough, it simply doesn’t work.
Restore Shield Android TV to Stock
P.s. Personally me I followed this instructions and kind of magically got it in bootloader mode. First done by instruction and then just gave up and pressed randomly and fastboot screen appear. Thanks God I had to done only once, if I would do again I wouldn't had patients
Good luck with this, hope you will get sorted
Here will be link about where I got instructions about hardware boot

Thanks a lot fro your help.
I was able to put the box in fastboot mode.
Since I'm not that expert can you tell me where and which rom I have to download (I have a french 16gb version of the box).
Then I'd need to know exactly what commands to performs (even a link to a tutorial is fine).
I really appreciate your help. It seems I can (hopefully) save the box.
EDIT: The fastboot command gave me a (not enough space) when I bricked the box. Is there a risk it could happen again while flashing stock? No idea how much space I have left on the box really.
EDIT2: I found this page: https://developer.nvidia.com/shield-open-source
and I'm downloading this rom called nv-recovery-image-shield-atv-upgrade2_1.zip
and Intend to follow these instructions: http://developer.download.nvidia.co...TV/Upgrade-2.1/HowTo-Flash-Recovery-Image.txt
Can anyone please confirm I'm doing right?

EDIT with joy : I followed all the steps using that rom and it seems everything worked. I reconfiguring the box now. Thanks for help.
basically the procedure I intend to follow is this part (please confirm it's ok):
To flash this recovery image to your SHIELD, run the following commands from
the directory where you extracted the recovery image package. If this is the
first time you have done this procedure, you must unlock the bootloader. Get
DTB file name to use for flashing for your product(see below):
P.s. maybe Since past fastboot commands failed and I only flashed system from zulu99 I could skip the 'fastboot flash boot boot.img' command so if it fails again I still can attempt the fastboot process again?
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
fastboot flash dtb <DTB file name>

You are on the right way with those links
P.s. You can do manual one by one entering or paste and copy those commands or (I'm doing) drag and drop file "flash-all.bat" on cmd previous opened there where you have abd/fastboot etc files and extracted RIGHT FIRMWARE (like shift and right click mouse "open command prompt here"
And after this all sit down and relax
Anyway you are on the right way.
P.s. Hope you download adb fastboot drivers somewhere from Internet !?!

OPT is stuck and I cannot fix it

I was trying to install The paranoid custom rom 6.0.1 to my OPT when I started to running into an issue with boot looping. The phone would run through the bootup animation and then say it way starting up the apps. Once it was done with all the apps it would just start rebooting again. I tried to get into recovery to flash an old rom but I couldnt get in to recovery (holding the volume down and power button just turns the screen on and then back off.) I then tried this firstaid script I found on here that would supposedly install an older twrp and allow me to get into recovery mode, but that has not worked. And now I cannot even get the phone to go to a boot animation, it just sits on the oneplus logo. Adb is not detecting my device on windows or mac, but fastboot is working. At this point I have no idea of what to do, becuase even if I get into recovery I dont have a backup rom stored on my phone. If anyone has any ideas, I please share, I am in desperate need of help here.

Flash fastboot images search and follow naman's unbrick guide, skip the data partition to keep your files

This thread will help you, https://forums.oneplus.net/threads/...wrp-root-nandroid-efs-backup-and-more.345478/

if you use twrp recovery and is not working on the Vol+ "-", try this way : RENAME your recovery file into twrp.img and flash it again.
If is not working,
following this thread first:

fastboot flash recovery twrp_first[1].img
Reboot phone to recovery
go to wipe advanced wipe wipe data and system only
go back to home menu open advanced then terminal
enter this command exactly :
Code:
dd if=/external_sd/userdata.img.bz2 | bzip2 -dc | dd of=/dev/block/bootdevice/by-name/userdata
that will take a loooonnnnnnggggg time approximately 30-45 min
after it shows # in terminal again do this command :
Code:
dd if=/external_sd/system.img.bz2 | bzip2 -dc | dd of=/dev/block/bootdevice/by-name/system
reboot and it should take a loooonnnngggg time but eventually it will finish and you restored if not try asking some of the devs for pointers:laugh::fingers-crossed::highfive:
Make sure you thank everyone who helped aslezak gave me the commands and the userdata img as well as the system img yuweng provided the first semi working twrp (and a few later that are experimental)

That one don't work either

FULL ROOT... ON MY HUAWEI XT2!! Twrp supersu and custom rom !!!
Sent from my HUAWEI H1711 using XDA Labs

The problem with this seems to be, at least for me, that a .bz2 file is not recognized by the recovery as an installable zip.
The dd trick worked for me, but the system image here, is not full stock. IT seems to have a mix of super_su and magisk in it.
Root is working, but I can't seem to mount system as r/w
So trying to figure this out. I used this image to do a restore, and my phone was rooted with magisk.
First time a program tried root, it said that super su was installed. When I went to another one, it said that magisk was installed.
Anyrate, at one time I was able to mount system r/w and make changes. Now it seems that I can't for whatever reason. I don't know exactly how I got it
to the state to be able to modify the system.
I actually pulled an entire copy of the rom at one time, with a dd command. Of course that can't be reflashed from twrp. But I'd like to be able to mount it somehow on a pc so I could do a stringsearch for all files that have an ro, in them to find the master files where the filesystems are mounted, and edit those....

the system.img requires a monthly membership, could an updated link using something like mega or mediafire be created please?

HELP PLEEEASE! Bricked h1711
Badly need mmcblk0.img for H1711! Had TWRP and phone was rooted but I screwed up and flashed a wrong IMG. Now I have the dreaded QHSUSB_BULK issue. Nothing but a black screen and a blue light. I googled "How to fix QHSUSB_BULK or Qualcomm HS-USB QDLoader 9008 error" and went on forum.hovatek.com where it said "This error is an indication that the phone is hard bricked due to a corrupted Bootloader. It could occur randomly or after you make a change to the phone, causing the phone to go into Qualcomm Emergency Download Mode." It also stated that I could fix it by creating a bootable SD card using the phone's original mmcblk0.img file using a program called Win32DiskImager. I don't have mmcblk0.img and I can't boot into recovery or fastboot. PLEASE PLEASE HELP!!!! Also first two links in OP's post don't work. Any files or advise you can contribute would be GREATLY appreciated! THANKS!

mmcblk0.img would contain all phone partitions including those with personal information like IMEI number and the /data partition that should not be shared.
Nobody should be sharing that without understanding it contains their IMEI number and other possibly personal information in /data and I'm sure it would be at least 8-10GB.
And what would you do with the file anyway if you can't get into fastboot or recovery?

What do you recommend I do? All I have is a black screen and a blue light? thank you btw

If it won't go into fastboot mode and won't boot, I think only Huawei can fix it.

What is the link to the info you found?
I have the image you need, but it is 15 GIGs in size, and there is no practical way to send that. I also have a system image, and a boot image with magisk in it, as per the OP.
P.M. me.
I don't see how you can recover this if you don't have recovery or fastboot, and can't boot into the phone. If the bootloader is corrupted, well I just don't know.
Can you get into twrp?
You do know that there are two recoveriess, one erecovery and another recovery.
It seems that POWER and VOL up may get you into one, and POWER and VOL down may get you into another one.
NOTE: I KNOW you can't flash the image via fastboot, cause I tried it. it is just to big.
The files are all to big to post here....
https://nofile.io/f/2sfHn8teU1s/system.img.bz2 I put this up 6 days ago for someone else. I don't know how long the link is good for.
This is the system image from the non-working link. You will need to untar it.
https://nofile.io/f/2sfHn8teU1s/system.img.bz2 <<<<<<<<<< file from Original Post
https://nofile.io/f/vTRffT3CM0s/erecovery.zip <<<<<<<<<< erecovery is same as stock recovery
https://nofile.io/f/3DRA4bYjdsq/twrp-xt2.7z <<<<<<<<<< Hweng's original twrp
https://nofile.io/f/uAET5bTqQVk/patched_boot.zip <<<<<< bootloader patched with magisk for a root that does not touch the system partition.
I'll try to put the 15 gig mmblockp0 up here if it will take it, but it is at the office.
I hope this helps.
I now also have a virgin system image, stock. The image given above appears to also have supersu installed it int.
at least it has a su in the system image. Where magisk, just patches the boot image as I understand it.

Any luck on that stock system.img? I formatted mine like an idiot and now sitting on a phone with no OS

same as above, i will even take the rooted system.img i have all other files needed.

I'm a little bit of a noob at all of this but could someone explain to me how they got twrp and root on their xt2? I can really only process step by step and I haven't found that anywhere yet. I'm getting this phone later today so it'd be really cool to get root on it

Blue light black screen fix

​My device suffered the same fate, only a blue light black screen unable to enter boot or recovery. I slowly removed the back cover using my fingernails and removed the two screws holding the metal plate above battery on the right. Popped the left most plug to disconnect the power flow and allow phone to power off completely. Be careful not to touch any of the metal near the plug or you will short. I plugged it back in and held volume down while I inserted USB connected to computer. Tada!! Back in action fastboot ready... So OK now what?? I can't seem to be able to flash an update. Zip just keeps saying failed to load, and system image is too big. Can someone point me to the correct files I need to get her working again? Thanks in advance.
