I was trying to get my A500 back to a stock OTA rom. I tried reverting back to 3.2 (honeycomb) using the instruction described (http://forum.xda-developers.com/showthread.php?p=33402012#post33402012). However ended up bricking my device. The only thing I can do is to boot into the TWRP boot menu (Power-VolumeUp). The recovery menu (Power-VolumneDown) fails with the yellow exclamation on a 2D android and booting straight up results in a boot loop.
I already tried various different images in recovery mode some of which have worked previously but none seem to work anymore. I suspect the boot loader is not able to find the recovery image or the SD card.
Since I am not able to boot I am not able to access the tablet via USB and so can't run any adb commands.
What are my options of restoring the device.
No, not bricked!! Replied to yr other thread

Months ago I flashed a Modaco custom ROM to my friend's San Francisco. There haven't been any problems of late, however today I attempted to flash a Froyo build so he can try out C2DM apps like Beejive and Facebook and I was unable to load up a recovery screen. When holding Vol DOWN and booting I just got a white rectangle with FTM inside it - indicating that there was no recovery image installed.
I tried flashing Clockwork Recovery with the ZTE Blade Recovery Manager 2.9 but it kept saying 'Unrecognised' after selecting the .img file, no matter which one I used or whether I changed the name or screamed 'hail Mary'. I attempted multiple reinstalls to no avail.
The device is rooted so I tried using Terminal from the Android Market and flashing the recovery image but although it didn't come up with any errors I was still unable to boot into the recovery image. All it does now is show a green android the same as it would if pressing VOL UP when booting.
I've even tried installing with fastboot for mac, but despite being able to input the necessary commands, fastboot doesn't flash the device and just sticks at 'waiting for device' when the recovery flash command is executed. I've tried connecting the device a number of times, rebooting etc. I have no other USB ports available and no access to a Windows pc at present.
Can anyone assist here? The phone still works fine with the Modaco ROM but it's a bit annoying if that's all he will ever be able to use now!
Thanks in advance.
Japanese_Jellyfish_RLS9_image.zip should be easy, and it installs recovery as well. Please read how to install it.
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.

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

I am a new user, and I would like to get some help with my Lenovo thinkpad tablet 1838-22f. 16g US
I tried to install CWM using this guys method:
http://forum.xda-developers.com/showthread.php?t=1831161
Now, after doing a factory reset from settings page, I cannot boot into recovery.
It shows that it's trying to go into boot recovery image, like it should, then it just shuts down and does it again.
I tried a hard reset, same thing.
I'm stuck guys, any help? :crying:
so now it does not boot?
you managed to install CWM or not.did you get any errors?
can you use adb now?
can you try to flash the original recovery?
I recently just picked up a nexus 4 and i'm trying to get a custom ROM on it. I updated it to 4.3 and that was fine. Went to install custom recovery and every since it will not boot! I've reverted to factory 4.3 using fastboot, and relocked it and locked it but still will not boot. It gets stuck at the X logo. Left it for an hour and won't get past it. If i install a custom recovery, it'll boot into the custom recovery no problem, but won't install root as it can't mount the SD card. I can get to fastboot mode no problem and flash stuff in fastboot but will never boot up. I'm puzzled as to what to do. I'm going to try 4.2.2 factory image here shortly and see if i can get it to take. I forgot to enable USB debugging so i think thats why i can't get custom recoveries to work. I tried pushing a ROM using ADB push but it wouldn't get there. Maybe it did as it said it did on the computer but the recovery won't read the memory. Any ideas as to what to do
UPDATE: Ok after flashing stock 4.2.2 from fastboot it boots.
UPDATE: turns out just having USB debugging was the culprit of everything. So make sure USB debugging is enabled before starting the whole process!
hello,
as the title says, my phone bricked while trying to go back to stock rom. this is what i did: i had a well working meticulus custom rom + the meticulus twrp recovery on my phone. thing is i need the google apps and they are not supported on meticulus roms. so i tried to go back to rom, downloaded a stock rom and tried to flash it with dragging it onto my sdcard and installing it from there. so this is when it bricked, the huawei logo appears at the start but it stays and nothing will install.
i tried to reinstall the adb drivers, no success. i can only use the bootloader but i can only flash a recovery, after trying to boot into the recovery via fastboot boot recovery.img it won´t do a thing. also the recovery is stock recovery all of a sudden (erecovery). and there i only have the option to "download latest version and recovery" but that gives an error aswell.
i´ve tried to reinstall drivers, no luck. when i do a fastboot devices it shows my device but when i do adb devices it doesn´t show up anything. so the usb driver is somewhat corrupted. my computer detects the phone when in fastboot only.
i´ve tried to reinstall the drivers a hundred times, i can´t get the phone to work anymore.
i would really appreciate it if someone helps me out.
