Can someone please help or toss me some suggestions on how to unbrick my tablet without sending to acer if possible this is whats goin on. It was rooted and running fine with CWM 1.7.3 from thor then the other day i turn it on and bootloop at bootanimation. i then enter recover to wipe and flash as usual but when i goto wipe it says error removing /data/data/com.android........... I heard my data partition was corrupted and proceeded with trying to really format that to no avail fearing my tablet was bricked i followed another thread titled how to unbrick your tablet!!!! it installed OTA ICS and wiped my recovery :crying: so now i have stock recovery and bootloop and the pc still recognizes the tablet in fastboot and APX mode but when i try to format /data in fastboot it says bootloader locked :crying: and when in apx mode when i try to use nvflash it says error during usb write then it says usb device not connected until i restart apx mode fresh. in the stock recovery it will flash OTA packages and finish install but still stuck in bootloop otherwise i just get the dead android guy with a red exclamation point. Any help or suggestions would be greatly appreciated.

Have you tried installing the patched bootloader? Remember, you have to have your SBK number you got from your UID. I found that NVFlashing using one of the earlier releases works best for me.
Also remember what OTA update.zip you are installing. Some of them, are just update patch files, which require a specific OS to be installed.
Did you try this thread?
http://forum.xda-developers.com/showthread.php?t=1699277
Basically, you decrypt the 2 update files, extract the contents of one on to your SD card. Try booting to stock recovery and see if it installs and boots.
If that doesn't work, then do the same with the other update file.
The 50x is basically bullet proof. There is always a method, and sometimes, it's finding the method that works is the hardest.
MD
I did finally get it. I let it bootloop hooked it up to my pc and used adb while it was bootlooping to get my cpuid and sbk since i had neither of those i couldnt do jack with nvflash. After i got those went back in apx mode flashed bootloader and cwm again followed thors instructions on how to really format data partition and installed rom like normal. Worked like a champ, but without cpuid and sbk i woulda never fixed it

[SOLVED] Okay so I got my i/o tab back up and working. See this post http://forum.xda-developers.com/showpost.php?p=14586131&postcount=2.
1. I downloaded those 2 things.
2. I booted into odin mode by powering off the device and holding the power and the left volume (volume down) until it brings me to a usb and a triangle sign with an android figure.
3. Press Right volume (volume up) to select the right icon on the screen.
4. Plugin the tab to your computer and load the odin3 v1.85 application.
5. Press PDA and find the PDA_SIGNED_P7105.tar.md5 file
6. Click start and let it reboot and it should be fixed! (well that's what fixed it for me)
So I tried installing the starburst rom on my i/o tab that I won (from phandroid!), anyways I was on an unlocked 3.1 rom that was rooted. So I installed rom manager from the market to get cwm on it. After that I backed up my current rom, and then I flashed the starburst rom.
After the rom finished flashing it rebooted and is now stuck in a bootloop of continually showing the samsung galaxy tab 10.1 splash screen.
I can't get back into cwm at all. I've tried getting it back with odin and with nvflash. Also fastboot isn't working for me (says waiting for devices both on my windows and linux machine). I've tried flashing both stock recovery and cwm via odin and via nvflash but nothing is working.
I'm not really sure where to go from here. I've spent the last 5 hours or so on xda and google. Any help would be appreciated.
The first attached files shows what happens when I select the USB image, the second shows what I get when I hold down the power and down volume, and the third is me flashing cwm through odin, but after flashing it, I still can't get into cwm.
I'm not an expert, but you may want to check the file you are trying to flash as it may be corrupt. Maybe try redownloading and flashing with odin. If that does not work you may need to reflash your firmware, I think there is instructions in the dev form on where to download. Also check if the IO edition is different model from the retail WIFI version.
Hopefully this is helpful,if not I'm sure someone else will chime in.
I checked the md5 of it and it matched. How would I reflash with odin? All I can see that I can flash with odin is the recovery. I don't know how to flash anything on my tab in it's current state. I can't get cwm back, and all I get is fastboot usb mode and odin. Fastboot isn't working and odin says it flashes the cwm recovery correctly and everything, but then it's not there.
Thanks for your input, any input is greatly appreciated. Was hoping to get my tab updated to a touchwiz rom, now I can't even use it.
I had same problem happen with mine out of the blue and it's stock I/O.
Maybe the thing i'm flashing in odin isn't for the I/O tab?

Did you fix it? I had this happen once before but I forget how I was able to get fastboot to work to issue a fastboot -w command.
Okay, so I think I made some progress. I was able to get fastboot working on a fresh computer that never had adb, fastboot, or the android sdk installed. I only have fastboot working on it and not adb. :\
So I tried fastboot flash system stockrom.zip but when rebooting it just shows the
splash screen. (I waited like 10mins). I now do have fastboot working so now what should I do?

which stock rom are you using? are you using the OTA 3.1 that is in the dev thread?
try that and lemme know what happens
also, if you can get into fastboot, you can fastboot recovery, ie get back into CWM and load a backup

I think maybe my partition table is effed up? I'm not sure.
I tried fastboot and flashing the backup that I had on my computer (fastboot flash system system.img ; fastboot flash data data.img ; etc), but it just hangs at the samsung galaxy tab splash logo.
I'm using the ota that comes in the files for dummies in the dev forum.

you are not in download or recovery mode. turn your tab all the way off, and then use the key-combo to get into the menu where you choose recovery or download mode.
then odin will see it
Jtag will available soon for 10.1
which key combination ??????????
there is nothing shown on my tab
no light
no charging sign
blank black lcd while in """'NVIDIA USB Boot-recovery driver for Mobile devices"""""" mode
in device manager
so good to hear that mine is not bricked
So annoying coming back to this thread because my tab decided to randomly boot loop again. >.>

Simply doing fastboot -w has never worked for me. It would just bootloop. Only way i've been able to restore it is through the steps I listed in this thread.
I really hope someone can help me out. I think I bricked my phone.
I tried to recover my phone back to stock with stock recovery so I can send it in for repair. When I installed 2.3.4 OTA update through zip, I accidentally clicked yes for updating 2.3.6. I didn't know, went to washroom and my phone won't boot. I thought no worries I'll install the zip again. Going into recovery, there's an android picture with an exclamation mark. I can't boot into phone and cannot load recovery. Someone please help >_<
download CWM and try to flash it through fastboot, and use that to flash a new img. im assuming you've done this before, having a custom recovery before now. if not, make sure you have fastboot setup, and if you don't go look through a rooting guide how to set it up then once you have it set up, move the new recovery you downloaded to the same folder as fastboot, then type
fastboot flash recovery name_of_recovery
of course replace the name_of_recovery with the exact filename of the recovery you downloaded. you can get the ClockworkMod recovery I think at www.clockworkmod.com
then boot into the new recovery and go to Mounts and Storage and Mount USB, and take the update.zip that you have and load it onto your SD Card, then go into the recovery and do as you would to flash the zip
Problem is, I don't think usb debugged was enabled. I tried to lock bootloader so I can just take it back to my carrier and say phone is screwed up, but when I tried, it said device not found.
The only way I think is using odin.
hi guys,
i flashed recovery using the manual method from this thread http://forum.xda-developers.com/showthread.php?t=2468858.
I wasn't able to use the last command
Code:
rm /sdcard/g2_security
I thought it didn't work , i also updated the my phone software.
When my phone restarted it went to cwm and now its stuck there.
Now when I try to boot I can either get in CWM or some Korean Recovery Menu with three option (i tried all nothing happend) or just stuck in boot loop!
I can't get in download mode by pressing vol up and plugging usb cable (tried all possible methods)
I will be glad if someone can help me out.
Thanks in advance
That's an unexpected situation to say the least.
So in short: installation of recovery worked, but you lost access to your ROM.
Correct?
Now, if you had a flashable ROM on your sd card you would be sorted, no?
I would say, get any compatible ROM, put them on a micro sd card and plug them into your phone. Flash through cwm...
Am I misunderstanding?
Otherwise there is always the fully back to stock option:

I was able to fix my phone using this thread. I was able to get in recovery but not in download mode. After executing these commands I flashed stock firmware through LG flashing tools.

The same exact thing happed to me. did u fix it, if yes can you please tell me how??
I have the same issue. Nothing mentioned in other threads is useful just because I CAN'T ENTER DOWNLOAD MODE. Totally stuck Help! Devs! Anyone!
Try installing some custom rom from recovery...after installing custom rom you can enter into download mode and do whatever u want...return to stock using kdz files or anything else..
I had my phone rooted on old Oreo version and wanted to reinstall the latest factory image. While I was doing this my laptop got a BSOD and the installation didn't fully finish. I redid the install but now my phone is in a bootloop. It will go past the Google logo but afterwards will loop on the dead Android guy with the ''No command'' message, same happens when I try to enter recovery mode. Is there something I can do?
I would flash TWRP and try wiping all including internal. Sounds like one of the partions is corrupted. You could do it with fastboot in bootloader mode but not sure of the commands.

You're probably not used to the stock recovery. The no command droid is normal. Watch this video, and see if you can get to recovery or bootloader.
so I made a really bad dumb mistake, I flashed over a perfectly good twrp to try a cwm recovery out, and I did so after installing a linage rom not even sure one exactly but I remember reading something about "insecure adb" or something?..anyway, all was ok until the needless recovery flash, reboot after yielded no o/s and worse no recovery partition at all, it just boots straight back to trying to boot recovery, followed by the endless bootloop, I can boot download manually, but now my pc will not recognize the phone at all no matter what I do nothing changes just not recognized. my adb setup was working great I flashed the broken recovery with adb so can someone please offer me a clue as to where to go now cause I'm out of ideas. MANY THANKS for any and all help in advance.
Verizon phone ??
Try Verizon forum .
CWM well out of date and usage now .
I would start by flashing stock rom via Odin .
