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

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.

GTi9195 bootloop and Recovery problem

my S4 Mini is stuck in a bootloop
i can get to recovery screen which is CWM 6.0.4.8 but no commands work they all produce the following errors
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
i therefore cannot wipe or reformat the caches, or do factory reset, or load ROM from a ZIP file.
i can also get into Download mode and i have used Odin to flash a number of different ROMS; stock ROM for my Carrier, Stock ROM for unlocked UK and Cyanongenmod. In each case it looked to by uploading correctly and Odin reported success but it did not fix bootloop
i also tried to upload different versions of CWM but although Odin reported upload successful the version of CWM I have never changed and the error remained.
i tried briefly with Heimdall but could never seem to find the files i needed in the format that Heimdall requires
ADB seems to talk to the phone but i'm not sure what i'm doing with it.
Fastboot will not "see" the phone.
can someone suggest how i can proceed. i don't care about keeping any data on the phone i just want a working phone back
thanks in advance

Did you tried to install an other recovery via odin? I had a similar issue with twrp 2.8.7.0 dont know why, but I flashed the newest twrp with Odin and then all works fine after that.

Try to use a new recovery, cwm 6.0.5.1 for example.

I have same exact problems............. i have an opened thread and i have found this thread by google but no resolution... this phone it's dead ?

[Q] Stuck on CWM recovery, can't install zip or flash with ODIN

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.
