Hi there.
I already looked the similar threads but before trying out something I would like some enlightenment.
My A500 runs ICS 4.03 (rooted). I never flashed custom roms or anything related.. While doing casual browsing with Firefox Mobile the tablet booted and since then it stucks on the ACER logo.
It does get listed with adb devices.
adb shell returns - exec '/system/bin/sh' failed: No such file or directory (2) -
Does any of these means that I should avoid/prefer specific solutions?
Is it possible to avoid erasing the user data? (I guess not)
Can I do a recovery without an external sd card, since adb sees the tablet?
Thanks in advance.

Have you tried to reboot the device into recovery via adb command (adb reboot recovery) and then just wipe cache and reboot system. If you still stuck at the Acer logo, then you will have to erase userdata.

I have good news. Through A500Manaager I got the SBK. Then I manually entered APX mode and with blackthund3r A500 APX Flash Tool I flashed the Skrilax_CZ's bootloader V8 and twrp 2.1.3
Through latter's filemanager I can see all the files I'd like to backup,
Now, is it possible to flash a rom over usb with fastboot?
im running clockworkmod v6.0.0.6 and unfortunately i was stupid enough not to backup the music/picture folders on this and installed kitkat update OTA. Now its stuck on the boot animation...
HOW DO I BACKUP THE FILES USING ADB FASTBOOT? I cant seem to be able to plug the device in and be able to look at any of the files! I have windows mac linux. PLEASE HELP i need to at least be able to backup..
EDIT: i got the ./adb working! so now i can pull the files off the device..
Now how do i fix the boot animation issue? it would be nice to get the kitkat working...
Guys, i just bought an used Nexus 4 and after flashing the cwm recovery and trying to boot in the recovery mode i get a few errors stating:
cant mount cache/recovery
cant open cache/recovery
I notice there are a few topics about this and the solution is to adb push or something, but the adb push command wont work in recovery for me, says device not found and i know my drivers are correct since i can fastboot and do stuff.
I actually got the device running perfectly flashing Chroma via sideload, but cwm wont work! I cant access anything from inside cwm... I also tried twrp and no luck.
I also tried a full original image flash, no luck
Can you please help me with this?
Thanks

when you flashed the factory image it should have brought you back erasing and replacing everything. In fastboot did you flash the bootloader, radio, system partitions (.IMG), recovery partition, and so on.? If not try this steps guide http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312/page194 its pretty detailed but it helped me after I wiped everything off my phone trying to learn. If that's a bit too much then try searching for wugfresh nexus toolkit. Both will wipe everything from your nexus then replace it and should get everything going
hello xda community
I made sure to try everything (or almost) before post here
my ZenFone 5 show a message that it cannot mount the cache partition and I am stuck on the Asus logo (I can access droidboot and recovery but I cannot replace them)
factory reset and cache wipe does not make any change (they return the same "can't mount cache" error.
I am trying to change the current droidboot and recovery to fastboot and TWRP but not matter how much I flash them, it does not take change (yes, I am unlocking the bootloader)
I am also executing a script to get the original partitions table back but when sec_offline_update_image.cmd executes the command "fastboot oem partition /tmp/partition.tbl" I get the error "FAILED(remote: GPT command failed)"
as this came out of thin air, I didnt have the chance to activate developer mode on my phone
I starting to get concerned .... any help?
thnk you very much in advance
@dgadelha any help ?
What are the specs of your Zen 5?

ZenFone 5 - A501CG T00J
Serial # with 0123456789ABCDEF issue
Box info: A501CG2 / A501CG-1F589 / CPU Intel Clover Trail Plus + Dual Core 1.6 Ghz, Purple, 8GB RAM
I already checked basically all links on Google related to the above issues (4 days Googling it already).
I really don't know what to do anymore.
A little more context @dgadelha.
2 months ago, I unlocked my bootloader for the 1st time and installed BlueLight 3.24.40.87... after the installation I locked my bootloader again using the boot, recovery and droidboot images contained in UL-ASUS_T00F-TW-3.24.40.87-user (Asus' official).
BlueLight worked fine with minor bugs for 2 months until past week when it suddenly started to crash a LOT, get slow and overheat (I didn't had time to fix it).
Then suddenly, all Android services and apps on the phone crashed and the phone turned off entering in a bootloop (Asus logo) everytime I reboot.
Since then I am getting the "E:Failed to mount /cache (Invalid argument)" issue when loading the recovery mode.
Since then I am also not being able to flash anything on my phone... no different recovery, no other fastboot and no other image... I get success messages on the flash process but nothing changes after restart (I can still access droidboot and recovery but nothing works there as the "Failed to mount /cache" error pops up for any action I try... recovery mode shows version 3.24.40.87_201).
When I try a system image via adb sideload I get error "Total xfer: 0.00x".
When I try "sec_offline_update_image.cmd" I get an error on the command "fastboot oem partition /tmp/partition.tbl"... the error is "FAILED(remote: GPT command failed)".
I have tried 2 different "partition.tbl" files... one that contains the "spare" partition and another one that contains "misc" instead... both failed.
I am now currently trying xFSTK (I don't even know what this does on my phone) and ASUS Flash Tool... ASUS Flash Tool returns "Flash image failure (FAILED (remote: GPT command failed))".
PS: I forgot to activate developer mode and other related options before the crash.
I hope that my phone is somehow alive... btw, thank you very much in advance!!!

Hi,
Did you have any kernel mods when using BlueLight?
Sorry but I don't know if it had a custom kernel, but a custom one could have lead a storage drive crash.
Also, xFSTK will just attempt to restore your droidboot and dnx/ifwi, not the partition table or w.e.
Maybe you could try extracting the Jelly Bean RAW file with 7-Zip, flash the droidboot signed image (should be like, fastboot flash fastboot file.img, or fastboot flash droidboot file.img), the droidboot signed image name might be something like droidboot.signed_POS.bin (it's an img file too, but with a bin extension).
After flashing that droidboot image, reboot your bootloader and try running the sec_offline_image_update.cmd again.
I wish I had Zenfone Assist active yet, but had to take down it.
Thanks
Hey jaabax, were you able to fix your device ?
Hi @vikrammarkiv.
Sorry for the big delay in response... I am not using this e-mail anymore and I quit fixing my phone.
Unfortunately I could not fix it and I ended up buying another phone.
Could you fix it?
Sorry again and hope you fixed it.
Best regards.
same issue, anyone got any update on fix?

Same problem, only fastboot and GPT failed (Asus zenfone 2 ze551ml). No solution
Exactly the same problem. It appears there are no fixes. How did the xf... thingy go?
Оh man.. I have the same issue, and can't fix it...
I tried a while back to flash TWRP I believe, but ended up with this message (see pic 1) and now when I try to enter recovery I get the message in pic 2. Also, It looks I can't enter download mode.
Any help would be much appreciated, I have been trying to get this tablet back up and running for a while now!
Thanks as always for all the help!
Same here, ive been trying to fix this thing for a few years to no avail. Honestly i should just throw the thing away but im determined to fix this thing. No download mode or recovery mode. fastboot seems to be the only option here but that also seems to fail.
If we can somehow get this thing into download mode, this would probably work.
https://www.reddit.com/r/LGgpad7/comments/6f5tt1
It's very complex but it's possible, its similar method to what's in this post https://forum.xda-developers.com/t/qd-9008-fix-tested-on-lg-v410-g-pad-7-0-us-att.3269057/
Thought I think there was a original post about this method which was more detailed,
Anyways I broke bootloader partition before and I managed to fix it in similar way without access to download and fastboot like in the guide.
What I did was install the whole system (partition with GPT and install every single partition including system on the SD card) but my tablet was still not booting from SD card, I somehow managed to get it turning off the SD card with a special QD 9008 cable, I can't find one online now will update if I do, then when it turned I somehow managed to root it (but again not sure how as it requires download mode, I could've done it via kingoroot or by injecting root into the system partition manually and then flashing it onto the SD card) and when you have root you can use terminal emulator or ADB shell to flash corrupted partition on your tablet with DD command, after it should turn on though I recommend reflashing it with flashtool after
