I'm getting a error flashing Nightlies (same one in my previous thread, where I tried all options and couldnt figure it out). Here's the error output from CWM recovery, hoping someone could read it and explain why the flash of a Nightly over a previous one is not working for me.

Anyway, I was using Miui V3 2.4.20 [2.6.35], and Google maps wasn't very happy with it. So I decided it was time to move on to the .32 kernal version, since the developer was going that way too. Downloaded a stock rom with .32 kernal, went to the pink screen and flashed, and then boot loop.
Luckily, I'm awesome, so my phone won't die on me. Tried flashing some roms through clockwork, no bootloop, just stuck at huawei logo. Tried flashing some stock roms, and at about 98% done flashing it goes error. Some parts get flashed causing my recovery reverts to stock, but I'm still stuck at the huawei logo.
Also, in clockworkmod I get errors mounting data and emmc, so that might be a problem. Other partitions mount fine.
I'm sure I'll find a solution eventually, so there's no rush. I've been in similar situations before. Just wanted to see what other people had used for similar situations. So if you know of something that would help, please let me know.
Found these through search (I'll do a better search again later), i will try them tomorrow:

After reading a lot of threads, attempting to flash a lot of roms (stock and others), replacing all kinds of images, and offering a sacrifice to the cellphone gods, still at the same problem:
To reiterate problem:
1) Stuck/reboots at Huawei logo
2) Flashing stock roms via pink screen never finish installing, get error message at ~95% finished (During install, unpacks fine)
3) Flashing roms via recovery say they installed, but still boot problem
4) This problem occurred while trying to downgrade from .35 to .32
My next step is to try using Linux to put the Dload folder on the internal SD card and try installing from there. I have a feeling it is related to the partitions having problems. I used both the "get back pink screen" and "data partition resize," maybe something went wrong with them that only appeared when I tried to go back to stock. I'll find out more when I install linux and can see if the partitions are OK or not.
I've always wanted to try linux, and now that my phone is broke I have found the motivation to do so. So a word of advice for people for people wanting to try linux but are too lazy to download the linux file: Soft-brick your phone, it gives you motivation.
UPDATE: I'm pretty sure my partition table is broke pretty bad. In adb shell, df gives me:
Filesystem Size Used Free
/dev 173M 64K 172M
/system 203M 200M 2M
/cache 127M 4M 123M
and that's it. No /HWUserData, /.cust_backup, /mnt/asec, /mnt/obb, or /data.
Would someone be as kind as to tell me how to fix the partition table? I've got a soldering iron, duct tape and super glue. Also, I'm not afraid to buy a "box" to do some Jtag stuff.
Anybody know what Blefish uses to format the phone memory? I read on his tumbler page and his github that he has altered the partition table (he split the /hwuserdata into three sections, which means he has the ability to create partitions) If I can get that tool, then I have a plan:
0) If my understanding is correct, the updates don't install because the needed partitions are missing, which causes an error. I guess the updates won't create partitions, just alter them.
1) Use the tool blefish used to setup the partition table as described in this thread: http://forum.xda-developers.com/showthread.php?t=1504488
2) Once the partitions are back, i should at least be able to get the blue screen, if I'm good, then I can put all right files in /dev/sdb1, which will get me the pink screen.
3) Using the blue/pink screen, I can install stock firmware, which should correct any problems that the partition table has. Maybe even install android.
4) Do the happy dance
5) ???
6) Profit
I've done my homework, searched the forums, made a plan, and cleaned my room. Someone please give me some feedback and at least let me know if I'm heading in the right direction.

I am using fdisk, the main partitioning tool for MBR table. You can check the table by doing fdisk /dev/block/mmcblk0 and then "p" which should print the current partition table. From there, you can also modify the partitions.

Awesome. I used to use fdisk back in the dos days, so I just need to brush up on my skills and learn the adb specifics. I really need to take the time to go learn all the commands associated with adb.
INTERESTING UPDATE: If I flash a rom with locked boot loader, I still get the pink screen but it doesn't work, i.e. I can't access the image folder via windows. If I flash a rom without a locked boot loader, pink screen works. Granted none of these roms actually fully flash, I still get the error near the end.
Fdisk = Permission denied, su = permission denied. Rooted boot image prevents me from getting into recovery, which means adb won't work. Any other way to get root? I'll try flashing a custom rom when I can get clockworkmod working again. For some reason I can't get recovery to load via vol+ & power.
Also something weird is going on. When it boots, it reboots once, then goes to stock recovery, tries to do a factory reset, gets errors on formating. Also in windows two removable disks appear, but I can access them. I take it that they represent the internal SD card and maybe the pink screen image folder partition. Tomorrow I'll try linux and see what happens.
UPDATE:
1) I can't use FDISK because SU won't work. I'm not sure how SU/root works on a software/partition bricked phone.
2) Rooted boot.img won't boot into recovery. SuperOneClick won't work because it can't find the data partition (probably because I don't have one).
3) I was going to try flashing a custom rom but for some reason I can't get clockworkmod working again. The phone will boot into stock recovery on it's own, after a couple of reboots. However, if I change the boot.img or recovery.img to anything else, it gets stuck at huawei logo or boot loop.
4) Unbuntu LiveCD won't work (says it can't find the kernal) even though I used the installer from the website and tried it both via cd and flash drive. Working on installing a dual-boot system now.
I'm really striking out here. Couple of questions if anyone would care to answer.
1) Besides recovery, how else can I establish an adb connection? Pink screen and huawei logo give me device not found.
2) Is there a root exploit available that doesn't require a data partition or is there a root exploit I can modify so it doesn't require a data partition? It's OK if it's a manual exploit, while I'm new with android/adb, I got plenty of experience with command prompt input from back in the dos days.
Also learned there is a HuaWei office in my town. Don't know what they do there, but if I don't make any progress after I couple more days, I'll go find out.

On pink screen, your device is just like any other mass storage device. So you can still use fdisk on ubuntu with the correct /dev/sdX path. You can also format the data/system/cache using other tools if you need to.

Sweet, so I just need to get Unbuntu working. I still can't figure out why the live CD/flash drive didn't work. Oh, well. When I get off of work I'll get to installing the dual-boot system. Thanks for your help.

Thanks. Unfortunately the project is on hold for a couple of days. My electric motorcycle has been having some problems and I've been repairing it. Also, I think I found out why linux wasn't working. Apparently the "alternative" downloads aren't useable as a live CD, which is why the kernal wasn't there. Anyway, it's been a great learning experience. Maybe after I "break" my phone enough times I'll learn enough to become a developer.
Doing some research before getting back to working on the phone.
Looks like Blefish is talking about using linux's fdisk, when I was trying to use adb's fdisk. That would certainly allow me to bypass the su problem with adb. I think I got all the correct files for my linux livecd, so that shouldn't be a problem. After I'm done with my workout, I'll try it out and see how it goes. It's time to learn how to use linux.
Update: Got unbuntu working. Storage devices are all /media instead of /dev like I was expecting. But I think I'm not looking in the right place.
Plugged in phone via pink screen and 3 drives came up:
System - has system stupp (app, bin, etc, fonts, ...) - sdb12
256 MB File system - image folder with all the .img and .mbn files - sdb1
136 MB File system - has fotapkg, lost+found, recovery folders- filesystem type ext3/ext4 - I'm not sure what this is, maybe sdb6? If it was data (sdb13) then I wouldn't get the error in recovery, If it was the internal SD card the filesystem should be vfat. If someone knows better, please let me know.
For some reason I don't have permission to access the lost+found folder, or so Unbuntu tells me.
Tried to used fdisk with system, got error: I don't know how to handle files with mode 40755
Also found some recovery log files in the fotapkg and recovery folders. I'll post it here incase someone can get some more useful information out of it. Does anyone know what all these (null) mean?
Tomorrow I'll get to work on learning how to use unbuntu and fdisk.

The sdb6 is indeed cache, and it is used for recovery communication between Android.
If everything would be ok, it would mount sdb1, sdb6, sdb12, sdb13 and sdb14 inside Ubuntu, so it seems that something is wrong at the end.
If you have 14 partitions, use disk utility from Ubuntu and try manually formatting the 13 for ext4 and 14 for vfat. Taking ownership is not needed, it should work either way.
Blefish, thanks for the help. Got unbuntu up and working along with fdisk and identified the phone.

Comparing with your partition table I see two differences:
1) the ending block of sde1 is 491520 on mine and on the original it is 30721, however the blocks are the same, so that is probably not a problem
2) sde13 is empty, and sde14 is missing.
This actually makes sense. When I was using MIUI, I reduced the size of the internal sd to near zero, since MIUI could only either the internal or external sd, not both. After trying to downgrade, I had a problem, so I tried to restore the internal sd card back to stock size, just to bring my phone back to stock. Something must have gone when I did that.
So if I understand the problem correctly, to fix this I need to:
1) Split sde13 into 2 partitions
2) Format sde13 to ext4 and sde14 to vfat
3) Try installing adroid again
Do I need to name the partitions a certain name or do anything else?
In the mean time I'll be looking into how to use disk utility and fdisk to deal with sde13 and sde14.
Had an idea that I only need sde13 (data) to get things working again, the system shouldn't need sde14 (internal sd) to work.
So I went to disk utility, found Qualcomm MMC storage and tried to format the free 2.9GB at the end. Got an error:

So, my partition table is corrupt? I'll need to figure out how to fix this.
Here's some options I've found:
http://forum.xda-developers.com/showpost.php?p=21572216&postcount=12
ksatta mentions a couple of ideas:
1) If someone backed up their phone using dd, I could use that to restore my phone.
Here's a link on how to do it: http://linuxpoison.blogspot.com/2009/04/creating-backuprestore-images-using-dd.html
dd if=/dev/sdX | gzip > /home/sdX.bin.gz
where sdX is the U8800
2) I could clone someone's partition table. If someone could give me a copy of their MBR that should work.
Here's a link on how to do it: http://embraceubuntu.com/2005/10/20/backing-up-the-mbr/
Create a backup of your MBR by doing a:
dd if=/dev/sdX of=MBR-backup bs=512 count=1
That should read “create a disk dump of the input file, which is /dev/sdx (change to hda, or hdb or sda, depending on where the MBR is on your computer), and save it in the output-file MBR-backup in the directory from where the command is issued. Backup the first sector only, while you are at it”.
3) gparted - it's some kind of partition tool. Might be able to use it to fix the error. Not sure how to use it though.
For now I'm going to look into gparted for Ubuntu. If someone can help me out with a dd backup or cloning the partition table that would be awesome.
UPDATE: For people following this thread, and to keep me more organized, I'll start adding more of the important resources I find. They may one day help you fix your phone.
https://bugs.launchpad.net/ubuntu/+source/gparted/+bug/434463
Seems a guy fixed his the same error with gparted. However it wasn't on a phone. Also I'm seem a lot of people refer to sfdisk. I'll need to learn more about it.
https://answers.launchpad.net/ubuntu/+question/113539
"I got an answer in a forum, which looks easy.
Do a
sudo fdisk /dev/sda
then type
w
to write partition table, without any modification of it.
The signature should be fixed."
Is this safe to do to my phone? I know I'll have to write the MBR eventually, but I have to get it right the first time. If I screw up, I may not be able to connect to ubuntu anymore. Anyway, the guy said it fixed the error with his harddrive, so it's worth a try.
http://www.thegeekstuff.com/2010/09/linux-fdisk/
How to use fdisk, in case anyone needs to know
So my new plan is to:
1) dd Backup and MBR backup - in case I break it worse than it is
2) try to fix with fdisk w or gparted
I think the change in start and end is caused by Ubuntu using cylinders/sectors/blocks. Should not too much difference though.
Using MBR restore would not work here, as it restores the main 4 partitions list. MBR uses EBR aswell, which is located at the beginning of every extended partition. So we would have to copy the EBR of every partition.
I'd suggest deleting sde13, adding sde13 and sde14.
When adding sde13, note that starting block should be at the end of sde12, so simply insert last block of sde12 there. If it gives error, simply press enter as it automatically finds free block after the last one. End block could be for example +500M so fdisk automatically finds the correct end block. Do the same for sde14, but note the start block again. sde14 end block should be the last block there is on the card.
After you've done that, do w to write and if it tells you to restart or something, unplug the phone, take out the battery and restart to pink screen again. Then try to use disk utility again or gparted (have not tested this) to reformat sde13 and sde14 to ext4 and vfat.
You should be safe until you don't mess with the primary partitions, especially the mmcblk0p2 and mmcblk0p3.
Thanks again for the reply, Blefish. I may have just fixed it. I'll know soon enough.
I did two things:
1) sudo fdisk /dev/sde12 followed by w
2) sudo fdisk /dev/sde followed by w
After that it enabled me to add the 13 and 14 partition. I used disk utility so I didn't have to worry about the blocks. Afterwards they mounted in ubuntu like they should.
UPDATE: Not quite fixed, but the rom installed without error. So I think the partition problem is fixed.
Now I just have a boot loop. I'll go back to ubuntu, clear the cache, and try installing from the internal sdcard
2nd UPDATE: Stock recovery gives and error about mounting the cache partition. However CWM mounts it fine. My partition problems may not be over.
3rd UPDATE: genokolar's "Custom you partition" file to return to stock file deletes my partition 13 and 14. Had 13 and 14 back working, used the file as per instructions, afterwards ubuntu drive utililty shows 13 and 14 as "free." So that is where part of my problem comes from.
4th UPDATE: Fixed the problem with stock recovery. Turns out froyo doesn't like ext4 partitions. Changed cache partition to ext3, no more error.
Here are some exerts from the CMW log when I tried to flash cyanongen. Can anyone tell me if any of these errors are problems, and if they are what they mean?

My phone is fixed. I have no idea how it became fixed, but it is fixed.
I placed b518 on the internal sd card, and installed it. Then bootloop. So I held both volume keys+power to try another rom. It installed again. Went to recovery, it did a factory reset. Bootloop. Went back to recovery to see if I could wipe the sd card. No option for it, so I did another factory reset and rebooted my phone. I left my phone bootlooping for a minute while I looked online for a Huawei service center, and then my phone booted. I gues it got scared and didn't want to go to a service center.
This been a great learning experience, although at times a major headaches. I want to thank blefish for all his help. Thanks to this, i've bee reading his blog and other stuff, and now will follow some of his other projects.
Now to downgrade back to 2.2!!!!
UPDATE: All official roms are working correctly (b136, b138, b518, b528), recovery (5.0.2.6) works. However I haven't been able to get a single custom rom to work. Tried a couple .32 MIUI and CM, but they all stick at the huawei logo. Did factory reset and dalvik wipe, get error can't mount /sd-ext during dalvik wipe, and still doesn't boot.
Maybe I need to try a newer verison of CWM? I tried the newer versions before, and I didn't like them. Buggy and often wouldn't find my sd card.
This thread must be made sticky because it consists of pure information about dealing with soft-bricks. Thanks a lot for your curiosity, you're my hero.
I have a semi bricked nook color. It will boot to the "n" screen on its own and no further. I can also boot into CWR or cyanoboot 5.5.0.4 from an sdcard but i can't mount the sdcard to install zip files to restore to factory. 8 failed boots does nothing for it either or a factory reset.
PLEASE HELP!!!!

We've been through this before, but just so I understand. If you copy the zip to the CWM card with the SD in your PC, and then you boot with the SD in the nook, it boots to CWM, and you can use the 'install zip from SD' option. But when you go further to choose the zip from SD, it finds nothing?
Thats exactly what its doing

That is so weird. And you can see the install zip is properly copied to the SD when you take the SD out of the PC and re-insert it back into the PC? Sometimes the PC goes through the process of copying and it looks like it is there, but when you take it out and put it back, it's missing.
I am using a mac, but yes it is there every time i put it back in the computer. It just gives me "E:Can't mount /sdcard/" when I select choose zip from sdcard
Hmm, a Mac. And that message is generated by CWM at what point?
I boot into CWM choose "install zip from sdcard" then "choose zip from sdcard" and then receive the error
You said before you had adb working. Can you look at a file in /cache? That is partition 7. The file to look for is /cache/recovery/last_log. See if you can pull that and look at it. It is a log of everything CWM is doing, including errors that happen.

That is weird. It is finding emmc, but not sdcard. It is finding the backup you put on emmc. And you are not able to push install zips to emmc (p8) with adb? Or if you can CWM is not seeing them when you choose 'install zip from internal sdcard'.
i just figured out I can push zip files to the CWM backup so I am downloading the factory update zip file to see if i can push it to that file and restore it with CWM. If it works I'll explain further what i am doing.
That won't work. The factory.zip must first be modified before CWM can flash it. I have a modified stock 1.4.3 that can be flashed by CWM
http://d01.megashares.com/index.php?d01=CiYdDmP
Use that.

Sounds Good
Link added above. Just download it, push it to emmc, and choose install zip from SD, followed by choose zip from internal sdcard.
Downloading now. Will let you know
ok its actually installing right now. when its done what do i need to do
See if it will boot to emmc.
I just had so thought why your SD card was not mounting. In your fiddling around with things you may have put CWM 5.5.0.4 on emmc in the boot partition. If so, and the SD was not booting, emmc recovery might be booting. You can tell which one is booting by looking in the upper left corner of the cyanoboot screen. It will say E0 if booting from emmc and S0 if from SD. If emmc was booting, it might not see your SD.
But that does not jive with the n screen getting stuck without the SD in.
Anyway, I am hoping that you got something different happening since you did not come back immediately saying it was still stuck.
Ok the nook is back up and running on its own thanks to your patience and knowledge. I only have one remaining problem. If I boot it with a blank sdcard in the slot it boots all the way through to the unlock screen then freezes and reboots continuously. If i boot it without a card it works perfectly but it won't recognize a card if i put it in at any point. Other than not being able to use the sdcard everything works. Got it registered again downloaded some books and even used a couple apps with no problems.
You definitely have a hardware problem with the SD slot. I am amazed we were able to get the CWM card to boot. I was really stumped. But I'm glad you have a workable nook now. And now you know how to flash things to it using adb and the CWM card.
I'm having some issues factory resetting my wife's Nexus 7.
The device has been running 4.4.0 for a while and was fine until it started boot lopping (gets to the lockscreen, sits there for a few seconds then eventually locks up and reboot).
It's completely stock (though I had it unlocked and rooted at some point).
I can get to bootloader mode but recovery shows "no command". I am sometimes able to bypass the error and get to recovery, full wipe did nothing.
I was able to get connected using Fastboot and tried wiping the device and returning it to stock using a factory image.
Everything appears to run correctly but when the device restarts nothing has been wiped and the rebooting issue remains.
I've tried to load a temp custom recovery (twrp) and it does load into it. I then tried to use the wipe feature within twrp but then again nothing really gets wiped.
At this point I'm not entirely sure what else to try to wipe it and reload.
I can only fastmode - adb doesn't work unless i flash the temp custom recovery which doesn't seem to help me do anything.
When you softboot a recovery, are you able to mount any filesystems (/cache, /system, /data)?
e.g. using adb check to see what is mounted
Code:
C:\bleh> adb shell cat /proc/mounts
do any of them (/cache, /system, /data) that are already mounted indicate that they are mounted read-only?
for each filesystem (in /cache, /system, /data) that are not mounted, try mounting them "by hand"
e.g. /data partition
Code:
C:\bleh> adb shell mount /data
do any of these mount attempts fail? If not, repeat
Code:
C:\bleh> adb shell cat /proc/mounts
did any of them mount read-only (instead of rw as they should have)?
Now go and unmount them all
Code:
C:\bleh> adb shell umount /sdcard
C:\bleh> adb shell umount /data
C:\bleh> adb shell umount /system
C:\bleh> adb shell umount /data
Now go through each of these filesystems and check them manually with "e2fsck" (TWRP has this, I don't know about CWM). You will be checking the block devices mmcblk0p{3,4,{9|10}}.
NOTE:
Grouper /data partition -> mmcblk0p9
Tilapia /data partition -> mmcblk0p10
These checks do not alter anything (-n option):
Code:
C:\bleh> adb shell e2fsck -f -n /dev/block/mmcblk0p3
C:\bleh> adb shell e2fsck -f -n /dev/block/mmcblk0p4
C:\bleh> adb shell e2fsck -f -n /dev/block/mmcblk0p9 [b][color=red]( Grouper Only! )[/color][/b]
C:\bleh> adb shell e2fsck -f -n /dev/block/mmcblk0p10 [b][color=red]( Tilapia Only! )[/color][/b]
Any errors for any of these other than complaints about lost+found being missing?
All of the above are just sanity checks to see if the typical ext4 filesystems used by Android are being created correctly during the fastboot flashing operations you performed. This is not a solution; I will respond based on what you report.
You may also want to capture a kernel log of the soft-booted recovery, e.g.
Code:
C:\bleh> adb shell dmesg > soft-booted-recovery-kernel-log.txt
Post the above kernel log to pastebin or somewhere instead of putting it in this thread.
OK, your turn.

I'll look at your kernel log in a little bit, but here's what sticks out.
1) Your userdata filesystem (mmcblk0p9) is corrupted - mildly. That shouldn't happen (although when it is bad you get pages and pages and pages of error output).
2) Your cache filesystem was mounted rw, but that doesn't necessarily mean that it was clean. You never ran a "e2fsck" check on either mmcblk0p3 or mmcblk0p4 (system and cache, respectively). Either that or they were clean and you didn't show the output. Which was it?
You should run the e2fsck checks on those as well and report back.
The recommendation that I will make for flashing the factory image is as follows:
1) Skip the bootloader flashing if you already have the matching bootloader version installed
2) Using fastboot, erase and format all three partitions cache, system, userdata:
Code:
fastboot erase cache
fastboot erase system
fastboot erase userdata **
fastboot format cache
fastboot format system
fastboot format userdata
** note this destroys all your data (but it sounds like you have either backed up your device or have moved beyond caring about this). I don't believe there is any reason for doing a fastboot erase of the boot partition (although I suppose if the bootloader understands "TRIM" behaviors, it would be possible that a "fastboot erase boot" operation changes the availability of pages in that partition for use in the wear-leveling free pool during subsequent writing operations. In the interest of safety, I would never allow the 4 sequential letters "boot" to appear in a "fastboot erase" command - to avoid accidentally doing something horrific like "fastboot erase bootloader". Better to simply skip erasing of the boot partition ("fastboot erase boot") than to run the risk of making a typing error and accidentally nuke the bootloader. (I don't even understand why the unlocked bootloader should allow erasure of the bootloader partition.)
3) Repeat the steps in my previous posts to check that the filesystems are being created cleanly by the fastboot format operation:
(3a) Soft-boot into a custom recovery and
Code:
umount /cache
umount /system
umount /data
e2fsck -f -n /dev/block/mmcblk0p3 [color=grey]# (system)[/color]
e2fsck -f -n /dev/block/mmcblk0p4 [color=grey]# (cache)[/color]
e2fsck -f -n /dev/block/mmcblk0p9 [color=grey]# (userdata [b][color=red]Grouper Only![/color][/b])[/color]
e2fsck -f -n /dev/block/mmcblk0p10 [color=grey]# (userdata [b][color=red]Tilapia Only![/color][/b])[/color]
They should all be clean, other than a complaint about lost+found being missing.
4) Now, perform the flashing of the factory boot.img & system.img - NOTHING ELSE. The important point here is to NOT FLASH "userdata.img" from the factory image.
Code:
fastboot flash system system.img
fastboot flash boot boot.img
5) Repeat the steps in my previous posts to check that the /system filesystem is clean, e.g.
Code:
umount /system
e2fsck -f -n /dev/block/mmcblk0p3
.
If everything is clean, go ahead and try booting the tablet into the normal OS
[Edit] I looked through your (recovery) kernel boot log.
I didn't see anything terribly unusual, except some indications of EXT4 filesystem repair. That shouldn't be happening, but could have been caused by:
- a kernel crash or maybe bootlooping
- you hard-crashing the device by holding the power button down > 15 seconds.
The good news is that I don't see anything unusual happening where the kernel reads the device partitioning information

PS
I the post above - after step 3a - you can manually check to be sure that everything has really been erased from those three partitions by mounting each of /cache, /data, and /system, and then running a "df" command. The usage should be pretty close to 0% for all 3 of them.
BTW, I was a little sloppy above about giving the recovery terminal commands without prefixing them with "adb shell". I assumed that you know that you can just
Code:
adb shell
... (linux commands)
exit
with the custom recovery (soft-)booted, and then you will be sort of "logged in" to the device. You can tell the difference because of the command prompt you get. "Logged in" to the android device's recovery, it will be a "#" character. If you are on the PC you'll have the DOS/cygwin prompt, .e.g "C:\some-path-or-other>". You might already know that, but I thought I should mention it.
Man I truly appreciate the help!!!

Now the tablet will still boot to the lock screen and shows the wallpaper that's been set before... Sticks there for a few seconds then restarts.
I'm just not understanding why it would tell me that it's deleted stuff but isn't doing any of it.
Also like I mentioned before the stock recovery shows "no command" every time I tried to load into it - I've managed to get past this to the second where you can select the full factory wipe but as everything else it didn't wipe anything.
I guess I would like to see some unambiguous evidence that there really are still files present after erasing the partitions and doing the format (but before flashing the boot.img and system.img files).
That is
fastboot erase cache
fastboot erase system
fastboot erase userdata
fastboot format cache
fastboot format system
fastboot format user data
fastboot boot your-custom-recovery-image.img
(... custom recovery boot completes... )
adb shell mount /system
adb shell mount /data (will fail if already mounted)
adb shell mount /cache (will fail if already mounted )
(... and finally ...)
adb shell df /system /data /cache
or if you please you could do
adb shell ls -ld /data/*
adb shell ls -ld /system/*
adb shell ls -ld /cache/*
both /data and /system should be empty; /cache might have a few files from activity in the custom recovery.
Or at least that's the way it *should* behave.
PS The "no command" message displayed by the stock recovery is normal.
Tried that and it appears that the format commands do process but they don't appear to be deleting anything again.

When I ls the data partition I'm still seeing all the files and apps installed.
I'm not sure if there is a way to use the adb shell to format the partition (or maybe a recursive rm -f).
I'm also not entirely sure if it would actually do anything since it's not doing it in fastboot.
Like you mentioned at this point I'm not concerned about any of the data on the device as I do have backups. I just want to have it completely wiped and start from scratch.
Would having rooted the device at any point (and unlocked the bootloader) have anything to do with it?
I was running on Stock rooted for a while but then when my wife started to have problems with the device boot looping I ended up going back to stock (using the flash stock + unroot feature) and the "soft-bricked/bootloop" option).
I recall being able to side load 4.4.2 and everything seemed to work for a little while but it's doing the same thing now which makes me wonder if anything was actually fixed when I reloaded it last.
I did a complete wipe when I migrated to 4.4.0 which worked.
Same problem
Quite a few others have same "Read Only" problem I think.
I have tried everything. Seems to obey... but reverts to previous condition.
I reckon it is a hardware problem.
I've ordered a 2nd user motherboard for mine.

Ugh. Well, you gave it a try. But that does seem to strongly implicate the hardware.

There is the utility mke2fs in the recovery. But yeah, If the bootloader can't write it seems highly unlikely that the linux kernel would be able to.
The only other moon-shot-odds thing I can think of (which is admittedly extremely far fetched) is that somehow the "persistent state" managed by the bootloader has some kind of read-only toggle in it (something like a software test mode?) that got flipped, and erasing all partitions in the device plus the bootloader before immediately re-flashing the bootloader** could change something. The worst case conclusion of this kind of activity would be a harder bricking, but it sounds like the hardware is written off already. More likely, the fastboot operations would act just the same (read-only but no errors thrown), and you would never really change *anything* on the tablet. (The only way to tell if it succeeded might be to flash a different bootloader version than the one presently on the tablet as it display's it's version number on the fastboot splash screen) As I said though, this is a pretty wild idea, and frankly the chances that the entire eMMC flash chip went read-only in totality is a far simpler explanation.
Sux that your wife's personal info is going to enter a wastestream of undetermined disposition. Puts someone with a legitimate warranty claim concerning hardware in the awkward position: "destroy the memory chip now and lose my warranty - or throw my personal information into the wind in order to claim my warranty?".
Sorry.
** I'm not recommending that anybody willy-nilly erases and reflash their bootloader; it is just too dangerous. It should be regarded as last-ditch move of desperation - which is where the OP is now. Perhaps the erasure of all partitions at once allows the eMMC chip to rotate flash pages out of (and thus other pages in the device into) the bootloader partition as part of device-wide wear leveling?
But because I brought it up, I should oblige myself to state the following safety measures when bootloader flashing is performed manually:
- phone/tablet battery is fully charged (& even better if the fastboot/adb PC is a laptop w/ a working battery)
- verify the length and MD5/SHA-1 signatures of all flashable image files before beginning
- make absolutely certain that no power loss or rebooting of the device will occur between the time the "fastboot erase bootloader " command and the "fastboot flash bootloader bootloader-image-file.img" commands are performed. (The most obvious way to insure this is to perform them back-to-back, the flash performed straight away after the erase).
- the behaviors of the new bootloader don't take effect until a hardware reset, so the moment of truth after flashing a new bootloader is the command:
fastboot reboot-bootloader
.
Has anyone ever successfully resolved this? I am having the exact same issue as the OP and have tried everything I can think of. It seems like the partitions and bootloader are somehow write-protected; preventing data from being wiped or new data flashed.
Help!

I haven't yet... Pretty much wrote the device off but will try the last recommendation as a last try soon just not hoping for much!
still no luck... last ditch was to wipe the bootloader and reload. Same thing happens.
I tried to even let the device drain completely to see if this would somehow help clear the storage... i guess i would have to wait many years for that to really happen
o well, I ordered a 2013 16GB model... hopefully it won't be an issue with that one.
The old one will likely go up on ebay for parts (less the memory modules that I'll likely remove).
Okay so I recently updated my s4(att) from cyanogen 12 to cyanogen 13 (latest nightly). I went to settings/security and chose encrypt phone. After about 30 minutes of encrypting it reboot and got stuck in a bootloop. I thought no problem Ill just reflash. I go to reflash my backup and it says error mounting /data. I try formating data, factory reset, and installing the rom from scratch. It seems my data partition corrupt. So I figure fastboot. Yet upon loading fastboot I cant get adb to see my device. I think I got the right drivers installed. But nothing. Any help would be greatly appreciated.
Edit: fixed.
Solution:
I found this and was able to shell in via adb and format the partition.
f you wish to wipe the /data partition completely (including media like photos), follow the below instructions:
Boot into recovery.
Run adb shell in a terminal (Linux) or Command Prompt ("CMD", Windows). After a few seconds, you should see a line containing ~ #.
WARNING. Triple-check the command that you are entering here. White space and capitalization are important. Make any mistake here and you may accidentally wipe your whole flash memory including recovery images.
NOTE: if you want to encrypt your partition later, you have to leave 16KiB unallocated space on the end of the partition.
In the adb shell, run the command mke2fs -t ext4 /dev/block/mmcblk0p12. Substitute /dev/block/mmcblk0p12 and ext4 according to the recovery filesystem table (for /data). Output when running the command:
~ # mke2fs -t ext4 /dev/block/mmcblk0p12

of course always check your formatting the correct partition first
