Rom I'm using is flexreaper 10. The way I used to format a long process would be to flash back to stock then unroot flash stock recovery then.. hit factory reset. Then start over is their a faster way like my tf101 had superwipe from android revolution which is a flashable.zip that ran a script to format all user apps/data completely clean. I wish I could use that.. but can't so any ways would be cool to know..
Thanks

Never mind found a superwipe script made for a200 and works perfectly erased everything

Hey dinc.....Care to share? or post where it can be found? Thanks.
A200 SuperWipe.zip Works fine on A500
Just googled a500 superwipe sine my HTC Inspire 4G has it. We really need one for this device so here is what I found. I dont know how to write this although this looks like it was ripped off of mikes superwipe form android revolution I already told him about it.
Here is the site since I didnt make it I take no credit for it but i did test it here is my log file at the bottom is the link
maybe someone can refine it more towards our device.

http://www.acertabletforum.com/forum/acer-a200-hacking/3909-acer-a200-superwipe-tool-wipe-all-partitions-your-tab.html
Hello,
is there a (simple) way to get the location of the bad blocks, based on their hex address reported by mtty / info 8 ? Maybe without the need to install the ROM from scratch and save the log file?
...nobody?
i was wondering if my device has developed any bad blocks the other day. so the next time i had to restore my rom from a backup, i decided to look into it, using whatever steps/concepts i could remember.
i wanted to know which partition(s) had bad blocks, as opposed to a raw address that has to be interpreted later on. i remembered reading here that ClockworkModRecovery's "recovery.log" will contain this information when a partition or all partitions are formatted.
so i have a habit of formatting all partitions (except sd's FAT32) before i restore a backup. i did so and told CWM to copy the recovery.log to my sd's FAT32. perhaps you can use the same approach, i.e. take a CWM backup, then wipe all partitions, copy the recovery.log, and restore your backup. effectively, you will get your rom back just the way you left it and you will have determined if your device has bad blocks and how many and in which partitions.
then i continued with the restore.
when i had time later on, i opened the "recovery.log" i had copied earlier and noticed that it contained the following (notice the part in bold+underline below):
Code:

so i guess that part means there is a bad block in my data partition...of course some other partitioning could make the bad block land in some other partition.
but what i remember reading here on xda is that the phone's internal NAND management avoids bad blocks until all "spare" blocks are used up. after that, software (i.e. ClockworkModRecovery) can mark blocks as bad at the filesystem level...so really nothing to worry about (i think!) unless there are so many bad blocks that you have to "expand" one or more partitions' sizes to compensate for the bad blocks.
i hope the above helps...!
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.
Here is the output

Restore complete!
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.
Hi and thanks to anyone who decides to help me as my knowledge is limited.
I decided to flash KitKat as I play a WebView based game and thought the WebView Chromium of KitKat might make it run faster as it ran pretty slow. On the Paranoid Google+ page it says you need TWP 2.6 later and other sites say 2.6.x. I had 2.6.0.0, so did a backup of boot, data, system and recovery using TWRP, copied them to a PC and then tried installing KitKat, it failed. So I updated to TWRP 2.6.3.0 and it failed again, tried a second time and it updated
The game didn't work well on KitKat, so I restored my original version. I then decided to take screenshot of game not working on KitKat to complain, so tried installing KitKat again forgetting to update to 2.6.3.0 as the restoration of the backup restored the prevous 2.6.0.0 recovery, was a noob and tried again and i'm now left with a Nexus 7 in a boot logo loop.
Restoring the backup fails, as does installing the KitKat Zip or Opensensation . If I try flashing TWRP 2.6.3.0 via fastboot, it says success, but when I reboot the recovery i'm still in 2.6.0.0. I can boot into 2.6.3.0 using "fastboot boot", but it still won't restore the backup or flash. I also have a backup of the OpenSensation rom (wanted to try PDroid and it was the only rom I could find prepatched) which I made on 2.6.3.0, that won't restore either.
The error i'm getting in TWRP is "symlink: some failed"", "can't open destination log file: '/cache/recovery/log'" and "E:Unable to open '/cache/recovery/log'"
This is the end part of recovery.log in tmp

Which says update fails because file system is read only.
I've tried Nexus Tookit and it says it was successful. Used the stock rom before the most recent one.

But It has no effect. It's still stuck in a boot loop and if I reboot into recovery it's still TWRP 2.6.0.0. I can browse data/data using ADB sh and all data still hasn't been deleted. When using ADB, I can push files to root but once I reboot the device they are gone. If I do ADB Shell mount after attemping to install someone via TWRP I get
Code:
rootfs on / type rootfs (rw)
tmpfs on /dev type tmpfs (rw,seclabel,nosuid,relatime,mode=755)
devpts on /dev/pts type devpts (rw,seclabel,relatime,mode=600)

/dev/block/mmcblk0p4 on /cache type ext4 (ro,seclabel,relatime,user_xattr,acl,barrier=1,data=ordered)
If I then go into the mount menu and remove ticks in boxes and put them back I get
Code:
rootfs on / type rootfs (rw)
tmpfs on /dev type tmpfs (rw,seclabel,nosuid,relatime,mode=755)
devpts on /dev/pts type devpts (rw,seclabel,relatime,mode=600)

/dev/block/mmcblk0p3 on /system type ext4 (rw,seclabel,relatime,user_xattr,acl,barrier=1,data=ordered)
but if I try writing to cache, system, sdcard, data, it instantly switches back to ro and faiils. ADB push says it succeeds and file appears on device when it is mounted as RW, but is gone on reboot.
If I boot into recovery TWRP 2.6.0.0 and type adb devices, I get
Code:
List of devices attached
0123456789ABCDEF recovery
Which obviously I know is iffy.
If I do fastboot boot <TWRP 2.6.3.0>
and do adb devices, I get
Code:
List of devices attached
015d2109a660180c recovery
If it means anything, previously i've taken screenshots on the device and deleted others. Then connected to a PC in normal mode and what I see in the screenshot directory was from before those changes.
If it also has a bearing, when I connect the Nexus to the PC it tells me it can perform faster when connected to a USB2.0 port which it is. It Also has the power recharge problem, to get it to recharge I have to plug the usb cable in, remove usb cable and reinsert within 10 seconds, turn the screen off and leave it alone. As solution posted on Google Forums, but it used to charge normally.
I had a similar problem the other day and used the toolkit to flag an even earlier build (4.2) and I could boot.
Then do the OTA updates which will update your bootloader and then reflash whatever you like.

Thanks for your suggestion, unfortunately if I flash any stock which doesn't have the same boot loader as the device already has the flash fails. I get
Code:
writing 'bootloader'...
FAILED (remote: ())
so no error code and fastboot crashes after a couple of more steps. I can't write to the device at all, formatting, erasing does nothing even if it says it was successful. in TWRP I can't delete any file or change the permissions on any file.
So it's not something I know about, but i'm assuming the boot loader gets verified straight after being flashed, as my device will still have 4.23 regardless of what's being flashed the verification fails and fastboot on both the PC and Nexus 7 crashes. On the Nexus 7 in top left corner I see 'Signature Match'.
I also can't relock the bootloader. If I do "Fastboot OEM lock" it says success, If I immediately then try "Fastboot OEM Unlcock" it says it can't be done as device is already unlocked. It's like it's a hardware write flash failure, but it's a very big coincidence it happened when I was using TWRP.
Also tried removing the battery connector for a few minutes, did nothing.
Did you get anywhere with this? I've got the same symptoms - it "pretends" to flash partitions, but does nothing. Same error trying to downgrade the bootloader.
The installed OS has become flakey because its state never changes - it seems the whole device is stuck in read-only mode.
I'm suspecting its a write off
Oh - and I don't think its to do with TWRP - I had CWM installed, but I hadn't done anything but used the device for about a week - I have stock 4.4 + CWM + Superuser - and was happily using it until today when it started rebooting whenever I write much (like install updates). I think something about the flash has just "gone bad" - or perhaps been marked as non-writeable.
Same here..
I have experienced same problem.
My N7 is in Groudhog Day mode!
Whatever I do it reverts to its condition a fortnight ago... before rebooting.
It goes through all the motions... but Groundhog Day after reboot.
Must be hardware I think.
Any comments?????

Has anyone managed to solve this? I'm having the same problem. Bootloops and whenever I try to wipe data in TWRP (factory reset) it doesn't actually wipe anything. Help!

I've followed this up with Google Support (I bought the tablet from the play-store), and with it in the warranty period they offered an RMA replacement. They didn't have any hints or tips other than attempting to boot in safe-mode and factory reset the device (first-level standard support script), after factory reset failed they offered replacement.
This is only of help if your warranty is still in good standing - hint they were only interested in drop-damage or water-damage - unlocked bootloaders are no problem - although (a) I'm running stock and (b) Australian consumer law may give better protection than other locations.
Breaking news is that my wife's tablet failed in exactly the same way 3 weeks later. Her's had only ever been stock - in fact its bootloader was locked until the KitKat OTA reported errors applying due to mismatched system APKs. I suspect that was the first sign of bad flash. I unlocked and flashed stock KitKat. Then had ~3 weeks of no problems, now this. Hope that helps someone.

Well, just an update. Same problems still persisting. No solution yet. I contacted Google support but as I'm outside of the warranty period, I'm S.O.L.
Anyone with some other ideas?

Just adding a "ME TOO!". Makes me feel better that I am not alone... No matter how I flash, it says its successful, but on reboot, all is as it was before flash... Suppose I could get a Nexus 7 with a broken screen and fix it now... :/
I may consider myself lucky : it is late 2018 and my good old Nexus 7 2012 has fall into the Groundhog Day mode a couple of months ago... No way to flash, erase data or reset... Even erasing my personal files when connected to a PC doesn't work : all files are back after reboot... Bye bye Cyanogen ROM...
Turns out the read only issue is a known issue of hardware failure. I did end up replacing the motherboard and it was a good decision. Not too expensive and not super hard to do. I use an ASOP Nouget build.

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

Reconfigure device, choose language, enter name, install apps, etc.

of course always check your formatting the correct partition first
