Looks promising thanks for putting this up! I look forward to seeing if this successfully works on the various types of bricks.
Edit: Not sure what's up with your links or hosting, but yeah...doesn't work, just ads, then redirect to ....another ad. No download.
Edit2: Ok I've tried 6 times, no download, and I should mention links like this are frowned upon by XDA Mods, so you may want to switch to a host that doesn't require going through steps to get to the download, like dev-host. Looks like now I can't go past unless I sign up for something, which I may or may not agree with, which is kind of forcing users. Or I'm blind and not seeing it, always an option too lol

yes you can do this
In my case it does not serve for anything. Because as it does not recognize me the tablet by any means. The usb does not even sound when I connect it .... it is a pity, tomorrow a messenger comes to take her to him to the SAT. but thanks for the work
I have a photo of the current condition of the tablet, but they do not stop me to place external links...
I made a little video maybe this helps
asi se encuentra mi tablet. h t tp ://w w w .youtube.com/watch?v=G-TDTX-wvy4&feature=youtu.be
ok I tried it but it fails .. is there anyway to unbrick it if its in locked mode?
but this defiantly got me farther then any other thing

This won't get any farther then any other current method on a locked boot loader. This is for those having issues with recovery not responding so a rom install isn't possible.
What kind of brick do you have? There's a few kinds now.
Tapatalked from my Galaxy S II.
I don't know what type it is if I had to guess I would call it a complete brick but fastboot works (locked mode) and it sometimes will work with adb (also in locked mode)
The last step...
-- Install /sdcard/cm9-7-9-B29-a100-PM.zip ...
E:failed to mount /data (No such file or directory)
E:Can't mount /sdcard/cm9-7-9-B29-a100-PM.zip

That md5 error is normal, and isn't causing the install to fail, its the pretty much brick status your device is in that's causing that. Basically all those errors are saying you have no partitions on your device, so it can't do anything until that's corrected.
any idea where to start or how to get it back so i can return under waranty

Get it back how? Acer knows of the problem so just use the warranty.
Edit: sorry just realized what you meant. Sorry but no in its bricked state you can't restore it back to normal. You could try to fast boot the stock recovery and adb the stock boot loader, but it may or may not work. Doing any if the Modding voids the warranty anyways.

i ment to remove the recovery and the unlocker

Hey guys,
I've got a problem with my clockworkmod recovery! The last days my DHD began to freeze after unlocking the screen. The only solution was to remove the battery and do a restart. The time of using my phone become shorter and shorter till today I could only unlock my SIM card and then it froze. After that I wanted to flash an update of my firmware Revolution HD.
I got an error:
Flashing boot.img...
assert failed: write_raw_image("/tmp/boot.img","boot")
E: Error in /sdcard/Software/Android_Revolution_HD_4G_3.0.zip
(Status 7)
Installation aborted
When I want to restore with an old backup it says:
Erasing boot before restore...
E:format_volume: no MTD partition "boot"
Error while formatting BOOT: !
E: can't open /cache/recovery/log
E: can't open /cache/recovery/log
E: can't open /cache/recovery/last_log
E: can't open /cache/recovery/last_log
Maybe someone got the same error? Or maybe someone has got an idea to solve my problem?!
Thank you guys!
EDIT:
If I want to "wipe cache partition" there's the same error:
E:failed to mount /cache (invalid argument)
E: Can't mount /cache/recovery/command
E:failed to mount /cache (invalid argument)
E:Can't mount /cache/recovery/log

I have the same exact problem, I am trying to switch ROMs but I want to install CWM 3 over 2.5.1.0. It's giving me the same exact error when I wipe or try to flash anything. No solution yet..
Please inform me if you have a solution....!
I tried to downgrade with this guide:
http://forum.xda-developers.com/showthread.php?t=905003
But it is without success.
Don't know if it would work to format the cache and flash a new cwm version via fastboot...:-S
No ideas guys?
First we have to know about your S-OFF, do you have Radio S-OFF, ENG S-OFF, SuperCID?
If you have ENG S-OFF, you can try flashing ClockworkMod again in fastboot. I will write you instructions if it comes to that.
If you have Radio S-OFF & SuperCID, we can inject stock ROM into your phone via a PC, or load it from the SD card in bootloader.
Hey jkoljo!
Thank you for helping!
My DHD has permroot, ENG and RADIO S-OFF, HBOOT and SuperCID. A flashed different CWM's. It worked, but the error was the same - with all versions of CWM.
I tried to flash the RUU with this guide:
http://forum.xda-developers.com/showthread.php?t=905003
The first two steps worked fine:
adb push psneuter /data/local/tmp
adb push misc_version /data/local/tmp
But in the next line:
adb shell chmod 777 /data/local/tmp/psneuter
...there is an error. It says "no directory"
Today I have to assert that my sdc failed. With an adapter I put it into my laptop. First of all I backuped the whole card. Formated it and then I wanted to copy just the important files. There was an unkown error and after that I had no access. I formated it again but while copying there was the same error. I want to try flashing the RUU with another sdc, but don't have another one at home.
In which mode should I try to flash it? In the guide you should choose charge only and debugging enabled, but as you know my DHD does not boot!
You do not need to do those psneuter commands etc, just put the PD98IMG.zip into your SD (try to get a working card) and reboot to bootloader.
Doesn't I have to install it via CWM? Just reboot the bootloader?!
Should I copy the *.zip into the root of the sdc for that?
Not in CWM, in the bootloader. And yep, put the PD98IMG.zip into the root of the SD.
Mh...bootloader started the update. But while updating the Radio_v2 it hang up. It was working about an hour but it was frozen. And now I cannot start the phone...
Think there is no other way to send it to the support isnt it? :-S
Pull the battery and try again, if that fails again, try replacing the PD file, with a new copy, it may have gone bad/corrupt along the way, if that fails, I'm stumped. But I'm sure there's more that could be done without having to send it back to HTC.
I cannot switch the phone on. No bootloader, no CWM - just the black screen. It will not work to copy a new PD-File on my sdc. And I'm absolutly sure that the PD-File is not damaged - I downgraded it with the same file some weeks ago :-S
My canvas A1 is in bootloop.

IN SP TOOLS, DO NOT FORMAT PHONE.
SELECT UPGRADE FIRMWARE
USE STOCK LOLLIPOP FLASHFILE TO DOWNLOAD. FILE IS HERE.
NOW AFTER BOOTING UP, DOWNLOAD OTA FROM SYSTEM UPDATES.
i HAD GOT MYSELF INTO SAME PROBLEM. i TRIED THIS AND NOW MY PHONE IS FINE.
Long history: I was using Ivan_Meler CM 13.1 ROM for ~ 3 months, which was very stable. Last week I downgraded from build 10 to build 9 with only dirty flash and everything was working fine, just some occasionally FC. Then one night I left my phone ran on very low battery and when I woke up I found my GT-N7100 stuck on Samsung boot logo.
I'm still able to access ODIN download mode. When I get into recovery mode (CWM Philz Touch v6.26.6), I immediately get this messages:
E: could not mount /data to setup /data/media path!
E: Can't mount /cache/recovery/command
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log
E: can't mount /cache/recovery/last_install
E: can't open /cache/recovery/last_install
What I've tried so far:
1. Restore Nandroid backup (KOT49H.N7100UBUFNK1) using CWM
->>>>> got E: format_volume: make_ext4fs failed on /dev/block/mmcblk0p13
2. Flash, using both adb sideload and ODIN:
Stock ROM 4.3 (N7100UBUEMK4_N7100ZTOEMK3_ZTO) and 4.4 (N7100UBUFNK1_N7100ZTOFNK1_ZTO), downloaded from Sammobile
->>>> got "NAND write fail" on ODIN and
->>>> on adb sideload the file loads 100% but I got "error:closed" and after "failed to write data 'protocol fault (no status)' "
3. Flash only the hidden.img of the stock ROM's mentioned above, I got "PASS" on ODIN but after phone gets stuck on boot Samsung logo
Tried this guide, using stock 4.1.2 (N7100XXDLJ2_OXA_FACTORY) with and without re-partition
->>>> got "NAND write fail" as well.
So I have ran out of options can anybody please help :crying::crying::crying: I really like my Note 2 and I don't have money to buy a new phone right now.
SDS for 99%
Try flashing the latest stock rom using a different USB cables, different versions of Windows, and different USB ports. If none of these work, the memory chip may be damaged.

When trying to flash a stock rom, did you try different usb cables and usb ports?
Did you confirm the model number in download mode?

I think it's Hail Mary time. See your PM for info using Heimdall and pit file. I have put what you need on the ftp server. ~metafizik
I had this happen with mine once and had to flash older version stock ROM & Pit .from there I had no signal, after rooting & philz...flashed new modem..then updated to updated ROM. Oh and mine also failed adb until I got a new battery.Also I would suggest to uninstall and reinstall drivers on computer...both Sammy & Heimdall.
