Hello everyone, i have a Iconia Tab A501 and i can't get it to work.
When i power it up it just hangs on the Acer logo. I can enter in recovery, but any rom (i tried 3 of them) that i try to flash doesn't work. The green android with the rotating 3d-thing is there but after a few seconds it's gone and at his place there is another android with the open belly and the red warning symbol.
I can't flash it because i don't have the cpuid. The bootloader is locked. What can i do?

Sorry if this is a bit late. I'm not sure if this will work for a Iconia A501(I have A500), but you can try a hard reset.
To do this, power off, hold down volume UP(not down like to enter recovery), power up, then toggle the screen lock switch back and forth (I believe you can release the power button while doing this, just keep holding to volume control) This should equate to a factory reset(I've never done it, so I'm not sure). If it doesn't work try it again(apparently it takes a few tries)
Hope this helps!

It doesn't work. It turns on showing the acer logo and hangs.
It's probably done the same as mine, died permanently. Nothing you can do about it. It's most likely that the mmc is broken or has become unsoldered. Sorry but I suspect it's toast.

How long did you wait? It takes some time to boot up first time. If you still have issues you can try force it into APX mode and flash the bootloader and recovery again, then reflash the stock ROM in recovery. http://forum.xda-developers.com/showthread.php?t=1619913
Or it could be completely dead like zardoz99 says. That would seriously suck.
EDIT:
Read again. Y U HAVE NO CPUID!?

I waited all the night.
The tablet isn't mine so i don't have the CPUID. However, it enters in APX mode and in recovery.

Sorry, being even in APX mode you can't do anything without your CPUID. Sorry, but the only thing I can think of now is to send it in to Acer to repair.

My S4 only boots into stock recovery with blue text 'recovery booting'. I cannot get into download mode or boot normally. I've tried to data factory reset but the same thing occurs and also I cannot clear the cache as it ends in an error. I have managed by fluke a couple of times to boot the phone up in normal. but cannot install superuser to get root. I also restored with kies but again reboots into recovery mode. please help as I don't want to keep booting into recovery. any questions ill try and answer them.

That's weird. Can you install the Android SDK or ADT and get adb.
Then plug your S4 to the computer (I assume the drivers are installed?) and open up cmd. Set adb to your path variables or just browse over to the adb where you installed your SDK and run
Code:
adb devices
to see list of devices and check if yours is there. Then type
Code:
adb reboot download
Let me know if that works.

Did you connect the phone to the PC? Seems that it cannot detect your phone. Bad drivers maybe? Try installing these:

Well if CWM works, and you flashed a stock ROM using Odin, does the issue persist? If so, it could be a hardware issue then.
EDIT: Although the issue in the OP seems to be solved partially no? Can you boot normally to your ROM? Can you boot to recovery (vol-up + power)? Download mode (vol-down + power)? Anyone of them through adb?

Do you get a bootloop? Download a zip of a ROM and flash it through CWM.
Can you still access download mode through the hardware buttons or through adb?

Every time I boot the phone it has the blue text saying booting recovery and boots into clockwork. I cannot access download through either adb or pressing the buttons. When I press down power and menu the phone freezes on samsung black screen.

You're supposed to press vol-down and power. Not menu. I guess that's a typo?
Anyway, if it doesn't work in those ways, I'm not sure what's left besides taking it to the shop and getting it replaced.
Does adb devices detect the phone as online? If so, you can try this toolkit and maybe that boots you to download mode?

No its not. You push in down volume, home(menu) and power button for ODIN and up volume, Home(menu) and power for recovery. Have NEVER got into download or recovery by holding volume up\down and power. Not since my Gtab 7" 1st edition....

What. That is totally weird. You are right but I can get into both recovery and download mode without touching the home button.
@spongerob500: Try what ultramag69 suggested with Menu button. Sorry about the wrong info in that regard, but on my phone I don't press the Menu/Home button.
EDIT: Sorry @ultramag69, it seems that both methods work. So no need to hold the Home button!

update - cannot get into download or odin mode with the buttons. what im gonna try to do is install a custom rom. where can I find stock roms also please? can I flash the stock ones through recovery too? thanks.
I was on efficient rom 3.3 and wanted to update to 3.4 but I was on some older versions of bootloader and modem so I wanted to update them first before moving to efficient rom 3.4. So I downloaded the BPHJ BL and CP for 935F, opened Odin and successfully flashed the files from download mode, it said the flash was successful and the phone attempted to reboot (as it normally does after an Odin flash), and now it's stuck at the Samsung logo with a red "recovery is not seandroid enforcing" in upper left corner. I try to boot into download mode by volume up+power+home button, the phone tries to do it but it gets stuck again at the same screen. If I plug my phone to the PC now, Odin doesn't even recognize it, it doesn't say added or anything, it's like the phone is not even connected.
I know I flashed the correct files because they are for the 935F (exynos international - my phone).
How the hell did this happen? Is the phone dead? Can I try anything else?
You have to get into download mode, otherwise it's normal that ODIN doesn't see anything.
Keep trying to get into DL mode. I've read several times here that people had the same problems with getting into DL mode while being stuck in a bootloop, but eventually succeeded after a lot of tries.

Download mode is vol DOWN + power + home.
New bootloader also required newest version of TWRP.
So after going into download mode flash the newest TWRP and that's it!.

Yes the vol up was a mistake, I know up is for recovery and down for download mode. I tried booting into download mode and I still can't do it. I opened this up in the efficient rom thread and yes, I ran into this problem because I wasn't aware I needed the latest twrp version.
Anyway, I try booting into download mode by vol down+power+home and it doesn't work. I try vol dow+power and as soon as the screen goes black I keep holding on the home button as well, without releasing vol down and power. Still not working. The screen goes but instead of booting into download mode it goes back to the Samsung logo with the seandroid enforcing error. This is the first time I can't boot into download mode.

Have you try holding vol down+home+power without release them until the download mode come up?
What I mean is that you don't need to wait for screen to go black. Just holding the button combo and phone will automatically reboot and go into download mode.

Yes, that's how I usually do it. It doesn't work. I'm thinking of going with the phone for a warranty repair but I'm worried that red seandroid enforcing error will raise questions about root. I booted into download mode a lot of times before, I know how to do it, it just doesn't work.

You're not hard bricked or you wouldn't have any thing showing on your screen.
First hold the power and volume down buttons only til it black screens then as soon as it does hold buttons for download Mode. It sometimes takes many times.
I've also read quite a few people let the phone die then plug it in to charge and then hold the buttons for download Mode.
That's how a friend of mine got his in download Mode.

seandroid enforcing error means the device can't load the security policy cuz u voided warranty
you could always say something like your kid was playing with it and it went into a bootloop or that there was an OTA update and it stoped midway and now your phone wont boot up hope for the best if they decline u goto another store to have it replaced/fixed some ppl arent knowledgeable about voiding warranty and issue a replacement

When you try to go in recovery mode keep pressed longer volume up and home, release power when screen is on. I had this issue and worked for me this way
hello and thanks in advance. I recently installed twrp on my device and somehow deleted entire os. while in twrp I was informed of this but as luck would have it experienced a power outage, phone died and now adb is not finding device. since deleting os is it possible to get comp to locate it? all I get is the blue led and if I try to volume down power to boot recovery ligts go out. I do get a chime saying something is connected to comp but I cannot locate it. any advice would be great.
Have you tried to follow instructions to reflash TWRP? Can you put the phone in bootloader/fastboot mode?

Maybe missing something here but if can get to TWRP, power off then on holding volume up, you can flash any rom. Not volume down on my phone to get to TWRP, is volume up.
Good catch on the volume up button.

No way if you don't have adb working. Again, if you hold volume up button while pressing power on button, then release power on button as soon as you see boot screen, do you get recovery screen?
No screen reaction at all. Only the led when connected by us to computer it seems to charge and led stays lit blue after fully charged and red when still charging. I was hoping maybe there was a shell comand that would maybe push data enough to get into recovery at least.
