After upgrading to CM 12.1 everything was just fine. Got my tablet to charger and left it there for a while. And then i saw that i was looping.
It's trying to enter recovery (TWRM) "or something like" and restarting.
I' sitting on forum for 3 days already. trying to get some information and did lot's of things. Nothing helps.
Can anyone help me with this somehow? I'm almost crying and losing it (not really, but that what i feel inside)
Please. Any help. I think I've read all forum about this thing.
Thank you.
Do you have the real TWRP (i.e. not Safestrap!) & an unlocked bootloader?
don't think so. or better say i'm not sure about it. how can i check?
Edit:
i can run adb and after command "adb devices" it shows serial number and status: recovery.
i can use the command adb reboot-bootloader which puts me in fastboot mode. but then i try adb devices and have nothing there.
also, any command like "fastboot...." gets me to "waiting for device" and nothing more.
I tried two different computers. all ports. all cables that i've found.
Edit 2:
also after command "adb shell" i ca see "~ # ←[6n" and i can put there only reboot command
Well, first of all CM12.1 requires TWRP & an unlocked bootloader, if you don't have those, flashing CM12.1 was a bad idea.
So what happens during boot? Do you see the Safestrap logo and had to either wait 10 seconds or press continue to boot? Can you enter Safestrap there by pressing Recovery? Which Safestrap version is it (if any)?
The real TWRP can be accessed by pressing and holding Volume up, then pressing and holding Power, release both when the grey Kindle Fire logo appears on screen.
As having TWRP is a key requirement here, it's important to figure out what you really have (either Safestrap or TWRP).
And do NOT do a factory reset in amazon's stock recovery with Safestrap installed! Will brick the HDX!
As @Davey126 mentioned here you can check whether the bootloader ist unlocked by opening a fastboot prompt (i.e. DOS box, then change dir to your adb directory), then enter:
fastboot -i 0x1949 oem idme
You will only get a response if unlocked.
If you use Windows and get the waiting for device fastboot issue, try these drivers, could be a pain in the ass to install them in Win8(.1)/Win10 x64 though. And note that you probably need to (re-)install the original Amazon Drivers again to get the HDX noticed in Explorer in order to get files copied it.

Also verify you have a Kindle HDX ... not HD or generic Fire.
the fastboot command got me still only 1 message "waiting for device"
Tried to install drivers. While looping, in device manager, i can see "Fire devices: Android composite ADB Interface"
and "Portable devices: MTP USB Device"
If i enter fastboot mode, gets me to "Other devices: Unknown device" and i just cant figure out how to install the drivers. Tried to download some stuff. plugged, unplugged.
Edit:
After some work done with drivers, i input adb kill-server and adb devices and get "Serial Number Unauthorized"
So maybe i should change word "work" to "messing" with driver
what do i do from here... is there any live chat for it maybe? or i can call someone?
Well, do you have the real TWRP or Safestrap? Can you enter recovery?
well, only thing i get it's blue screen and "Teamwin" and after like 3-4 second restarts and go on looping same "Teamwin"

Still haven't answered Safestrap or native TWRP query (you should know). Do this:
- long press power until device shuts off
- restart device with power button (only)
- detail the 1st, 2nd and 3rd screens you see
If you do not have native TWRP (with unlocked bootloader) you likely borked your device with the installation of CM 12.1. Generally not repairable.

Ok, that should be the real TWRP, the Safestrap screen looks different.
This could mean you've TWRP installed, but the bootloader is locked. So I'd suggest to unlock the bootloader, you can't screw up anything, and can try this nice tool.

To check if your bootloader is unlocked (assumes you previously unlocked and still have the prerequisite software installed on host):
- power down device
- press vol-down + power; release both keys when "[fastboot]" prompt appears
- tether your device
- open a command prompt (assuming Windows)
- issue command: fastboot -i 0x1949 oem idme ?
- you will only get a response if bootloader is unlocked
If the (Windows) host displays "<waiting for device>":
- press <ctrl>-c to break wait
- start device manager (different window)
- located device with explanation mark (likely under "portable devices")
- right click -> update driver software -> browse my computer... -> Let me pick...
- select driver from list (ideally one that contains the words 'fastboot'); might have to try a few
- reissue above command
Bit of a PiTA ... might be easier to simply try the one click unlock tool as there is no additional risk to your device. It will either work or not.
I guess i'll check it only next week. Leaving all this things for the weekend.
I'll keep you updated guys.
Anyway, i really appreciate your help! Thank you so much for helping
same problem
Good evening, I am very interested by the article, in fact, I currently have the same problem and I began to be very sad. all stages cited by oreal Crast are similar to the ones I tested. when I enter the command prompt 'adb devices' I get the number of my tablet and status RECOVERY.
'adb shell' gives me "~ # ← [6n"
I even re installs the uboot, boot.img and TWRP freedom by following the steps in one tech site
but at reboot, by entering the command "fastboot oem recovery 0x1949 -i 'my tablet again has a boot loop on teamwin.
i want to resolve very fast this problem because i need my tablet urgently:crying:
ps: I don't think that I can meet these problems because after having bought my tablet to a friend (the tablet possessed CyanogenMod 11 android 5.0.1 I think) I did a factory reset . it is from this manipulation on my tablet reboot teamwin.
thank you for your helping

I assume you have an unlocked bootloader and were running 'native' twrp (not Safestrap) when the problem occured. Unfortunately, there is no known 'quick fix' recovery from this failure scenario (boot looping on teamwin spash screen) as you have tried to reinstall twrp without success. Someone very talented with android might be able to unravel the problem. Best guess (and it is only a guess) is the recovery partition became damaged to such an extent it the contents can not be replaced without performing a low level format/reset of your device.
Some curiosities:
- Android 5.0.1 and CM11? (impossible combination)
- TWRP freedom? (not supported on HDX)
Are your certain your device is a HDX and not some other model?
same problem
for android version I listed above, I do not know exactly because I have used my tablet a day without really paying attention to it but I think I saw the android 5.0.1 but regarding cyanogen, I just imagined it based on readings on the web.
for this is my tablet AMAZON KINDLE FIRE with a HD 8.9 and the TWRP I recently flashed, I got through the website wikicyanogenmod in the "on how to install cyanogen hd amazon kindle 8.9.
I can not post a link because I am new to the forum so I can only quote the sites where I could download my data.
* I really count on your help to all.

You still haven't made it clear whether you have an HD or HDX model.
You're on the HDX forum, but you're talking about documentation on the CyanogenMod wiki for the HD 8.9.
The problem likely stems from the fact that you flashed a recovery for the wrong device.

I searched the web and I have definitely amazon kindle fire HD 8.9 because even his appearance differs from the HDX 8.9.
no I do not really think the problem comes from the data flash HD 8.9 (wikicyanogenmod) because I flashed the data after doing a factory reset without actually knowing that this would pose a problem with amazon tablets.
the tablet was working well but I was unable to connect to the wifi. I thought it would be nice to change rom and install a suitable and stable rom for my tablet, but my operation I was surprised because I had never heard of this kind of problems caused by an factory reset
Dear everyone,
I have an ASUS MeMoPad 10 (ME103K) here which I vowed to fix. The user wanted to revert to Factory Defaults, lost power or something like this, and ended up with a bricked device.
I can only start it with power button + volume up, into Fastboot. Secure Boot is enabled.
I have Android SDK and minimal FastBoot installed. Have the Google USB Drivers on my desktop.
I tried flashing SuperBoot (ADB), but ADB simply lists "Waiting for Device". No devices can be listed. It does show up in Windows Device Manager: ASUS Android Bootloader Interface.
I have the following files available:
- SuperBoot r5
- Kernel: l-8064-r1_V12.16.1.12-201508071139-foss.tar
- UL-K01E-WW-12.16.1.12-user
- recovery-original-me103k
There is apparently no recovery.img for this device. The boot.img is in the UL-K01E-WW-12.16.1.12-user file
Power = ASUS logo then goes black
Power + Volume up = Fastboot
Power + Volume down = /
Power + Volume up+down = /
Is this the place I should be looking? I'm honestly not sure if I can catch up with the details: android.stackexchange.com/questions/124344/trying-to-flash-a-system-img-i-took-with-dd-failing
Any help would be much appreciated!

EDIT:
fastboot devices now detects #serialnumber
Alright, fastboot now detects my device. I installed PDANet which didn't do anything, and then downloaded another adbfastboot package which hit it.
I'm able to start writing boot.img, but that's what it stays at. It's an 8MB file, so it shouldn't take half an hour, I suppose?
I'm not getting any error message either, though.
EDIT: It seems that regardless of what commands I send, they stall and don't get executed. ADB doesn't seem to find any devices, only Fastboot does.
EDIT 2: Tried the same on my laptop. Different ports. Nothing goes further than for example "Writing 'boot' - that's it.

Hi,
after all these years I remembered my asus memo... Such a fine displsay but ... . I discovered an unofficial rom for another old device ( samsung gt 5830) and so I'd like to ask you whether you know any possibility to "upgrade" the MeMo or any other way to pitch / patch it. Your reply here let me think that you are very attached to asus memo, maybe you are still interested.

Same here, running the device on Lollipop is awfully slow, KitKat is somewhat better though but those are the only two official ROM's which can be found and installed.
Tried to unlock the bootloader to try different ROM's but bootloader is locked, despite all info here on XDA, nothing seems to work and the bootloader remains locked. Unlock APK's also give no result.
Running out of options here, any suggestions will be appreciated.
Hi all, this is my last hope at the moment. Any input would be highly thanked.
I own an ASUS Padfone 2 (KOT49H.WW_Padfone-11.8.4.23-20141028), stock firmware, that I managed to get soft-bricked, as I read they call it.
Phone is unrooted, ran KitKat, and I really don't know much more about it, I'm not really an expert unfortunately... No custom ROM or any of those pro stuff.
Scenario:
Every single app crashed upon opening, performed a reboot, phone got stuck into infinite boot-loop, at the company logo in the beginning.
What can the phone do and what I've done so far (all of which have been found through internet):
I can enter into recovery mode.
Did a factory reset and wiped cache partition before the following.
I entered what the phone calls "CSC mode", that other sources call "fastboot mode".
Followed this guide http://forum.xda-developers.com/showthread.php?t=2256977 , installed drivers, entered into the proper directory on CMD, and typed "fastboot boot recovery.img", but CMD says "OKAY" and all, but gets stuck at "booting...", even after like 15 minutes.
Then, for whatever reason I saw on the internet, I tried the command "fastboot oem unlock" that also didn't finish anything either in CMD or (seemingly) on the phone.
Then, I tried following this guide in CSC mode (even though I don't have the invalid kernel error) http://www.modaco.com/forums/topic/365818-padfone-2-invalid-kernel/#comment-2191432 , but also didn't get any further than CMD stuck at "booting..." for forever.
I suspect it could be possible to do some of those booting magic, but I have no clue how it works and how my problem inside the problem could be solved...
Thank you so much in advance.
(Please beware that I don't understand what the words bootloader, fastboot, flash or ROM mean. I'm a mere mortal.)
Hi All - I was trying to install a new image on my zenpad and ended up bricking my tablet. I think I ended up formatting everything outside of droidboot.
It only goes straight to the droidboot provision OS now.
i.imgur.com/tnzb5YT.jpg
I've tried the following:
1) Fastboot - It connects, but i don't have privilege to boot from an image. I can only do readonly type of tasks
2) ADB - my computer doesn't detect the tablet when using ADB shell, i think because it would only work if usb debugging is on... which i can't even get to anyway
3) ASUS FLash tool - there's no raw image available for this tablet
It seems like my only hope is the SD Download... but i think I need an image for that too? Any ideas and guidance please?

Hi,
I'm a noob, have tried looking online and in these forums for answers, but am getting lost and am finding myself in over my head. So please be patient with me.
I have an Onda v891w CH V1 tablet with a quad core Z8300 that runs an English Windows 10 and Android 5.1. In a bold attempt to root my Android install, I ended up bricking my device. It now gets stuck on the animated logo screen when booting and never boots either of the 2 operating systems.
I've been browsing online and found a few guides for Onda tablets, but most deal with different models or different versions of the v891w (like the V5, or the Z3735 processor). I believe I've managed to find an Android rom or firmware for my device here, but I'm unable to install it. I'm very likely doing something wrong, I just can't figure out what.
First of all, the thread talks about pressing ESC or F7. I've tried hooking the tablet up to a powered usb hub, along with a usb keyboard and the content of the V891W CH中性固件（适用于V1版本32GB）-20160701.zip file on a usb key. Unfortunately I'm not able to get into the BIOS. I suspect that the usb hub doesn't supply enough power for all the devices. It's an EasyAcc D70 7 port hub with a 5V input.
I noticed in the replies in the thread I mentioned above that people were flashing img files from fastboot, so I've tried booting my tablet in bootloader mode, unlocked the bootloader using the command flashboot oem unlock and tried flashing the boot.img and/or system.img files from the archive using the commands fastboot flash boot boot.img and fastboot flash system system.img. That results in the error FAILED (remote: Flash failure: Not Found). On the tablet it says Failed to get partition boot: Not Found
I'm not sure what to try at this point. If there's anyone who wants to take pity on a newbie and walk me through some step by step instructions on what to try, I would be very grateful.
Update: I've now also tried an Anker 60W 3 PowerIQ Hub to connect the keyboard with the tablet and the usb key, without success. Both the Anker and the EasyAcc USB hub are powered hubs. I could really use some advice on how to get this Onda tablet back operational.
