Hi all, I have an Android tablet (Diablotek D2-721, very cheap I know, but it serves its purpose) that is stuck in a boot loop. The real problem here is that this device apparently does not have any sort of recovery mode and being in a boot loop means it does not get recognized by ADB or any firmware flashing software.
I researched all day yesterday perusing forum after forum but almost every single solution requires booting into recovery. Is anyone able to shed any light and tell me what my options might be at this point?
Thanks in advance.

Maybe you can try to flash a recovery like CWM via ODIN.
Just my 2 cents!!
No, I cannot flash anything because the tablet refuses to talk to my computer while in this boot loop. I tried ADB, Odin, and the manufacturer's flashing tool but nothing would register the device as being connected. Plus I set up a second operating system and tried doing all of the same things on Windows 7 because Windows 8 has been problematic with drivers but it still made no difference. Still, thanks for the suggestion. x.O
The matter is null now. I just took it back and got another tablet, one with a recovery mode.
For anyone searching on this D2-721 tablet, be wary because with no recovery mode available it is very hard if nigh impossible to recover from a lot of things normally recoverable from any Android device. I tried for two days and spent hours pouring through forums but in the end my computer just could not talk to the tablet while in a boot loop. And trust me, I tried everything.
Thanks for the responses and help, it was appreciated.

Hi all, Does anyone know of an “unbrick” solution for a B70 Transformer on SBK2? I gave my tablet to my brother to try out as he was thinking of getting one and he decided to see how hard it would be to un-root it in case he ever needed to. Well I guess he answered that question as now it won’t boot past the EeePad/Asus logo screen. The loading bar gets about half way across and then it just sits there. I can get into APX mode, but cannot access recovery and it’s not recognized by my PC anymore for use with ADB.
I’ve searched around a lot and found several options if it wasn’t an SBK2 device, but it is, and I haven’t found anything yet.
Any advice, thoughts or ideas would be appreciated.
**Update - When trying to boot into recovery (Vol - and power) the status at the top of the screen reads:
Android US_epad-user bootloader , e. release by "US_epad-8.2.3.9-20110423".

Hi all,
I've spent a good two hours trying to figure this out. Generally I'm pretty good at these things, but there just isn't that much action or information on the Blu Life Play when things go wrong (L100a)
http://forum.xda-developers.com/showthread.php?t=2370987
In reference to the above link, I followed all instructions to a T. My phone is rooted just fine, all that is working perfectly. However, once I tried installing CWM using the first method, mobileuncle, not only did it fail, but it also entirely broke my recovery mode! Whenever I try to boot into recovery (vol+/power) I get a black screen until the phone eventually reboots itself.
I then tried method two using the flashing tool, SPFT. I used something similar pretty often, ODIN, with my old Samsung Epic. Again I run into a problem: I can't keep the phone connected long enough to allow SPFT to finish flashing the recovery. As instructed, I plug in the USB cable with the battery out, my computer chimes to let me know it has recognised the device, but- Three seconds later, it chimes again to let me know it has disconnected.
SPFT follows suit, detecting and starting the flash then getting interrupted 2 seconds later.
My phone is still able to boot, it is not bricked. However, it is very distressing to have no access to a recovery mode.
Help?
I have the same issue. Got my phone replaced under warranty and the new one I got yesterday will not boot to recovery. Only black screen. Hopefully we can figure out the issues.

Hey, it's good to hear I'm not alone in this. lopestom has been friendly enough to correspond with me about it and he suspects it's a new model of the same phone. I sent him a screen cap of the factory settings screen (VOL-/POW)
In the end we might be out of luck until more people get their hands on the new version of the phone.
Hi this is my first post on the forums, I've always found a wealth of information searching and never felt the need to ask for specific help but I am a bit stuck with my tf101 and I am hoping someone can give me some advice.
I have been running our old tf101 on CM 9 for the last few years but fancied trying something newer and a saw and read through the katkiss rom thread, so decided to go for that.
long story short is that it did not work for me and got stuck in boot loops. I am now in a position where I cannot access recovery and I cannot get into a download/fastboot mode to flash a new recovery from my computer. I don't think I am doing anything wrong trying to get into the download mode (power and volume up and plug lead in) but maybe I am? I've tried a new lead too but nothing I try gets me to the download mode. I'm using a linux (mint 17.3) computer and don't have any problems accessing my samsung phone with adb or heimdall.
Is there any other way to access the tf101 download mode? Am I getting it wrong? Is the device bricked?
Thanks in advance for any help.
Hi everybody, I am experiencing trouble with my tf101 S/N B70 after I tried to install a custom ROM.
I am not able to boot properly as it seems I have deleted the ROM before trying to install a new recovery. The result is the tablet is stuck on ASUS logo and it is not possible to boot, recover, wipe, basically anything.
I tried PERI, Easy flasher, but none of them seem to work.
If I plug the tablet on a PC running win7 but I cannot install the drivers.
Any idea or suggestion on what to do?
Up for help...
Any news here? Would somebody please answer this call for help?
Even if someone would tell me to just throw it in the garbage can...it would be appreciated!
I had the same problem. I was stuck on the logo too.
I discovered I was only able to cold boot by vol down and power like recovery but when the text appear, you wait 10 sec.
Do you have access to APX mode ?
Hope that will help

I have the same problem and your solution doesn't work. I see the text but restarting runs to same screen as before.
Research and learn look up ADB mode on this site.
These fine gentlemen do not have the time to repeat themselves day after day.
If you look for information as to how to use ADB and find the software you will succeed.
It really is easier if you find and fix. I am not trying to be a a hole.
Hi There,
Had an ongoing problem which i've tried and havent been able to solve. My phone died a week ago, to my surprise it seemed to be unable to power on. After trying more simpler methods, i figured my phone was bricked, as it is unable to boot into recovery mode regardless of what input or method i use. I have tried all sorts of broken data tools .ect. before i tried flashing a Stock Rom onto the device, as i have lots of pictures on the phone i seriously don't want to lose.
I tried installing TWRP onto the phone, no luck as it couldnt boot into recovery mode regardless of what i tried. It will just display the Samsung logo still. I've now tried to flash stock firmware onto the device using Odin which gave me a "FAIL!", "complete(write) operation failed". I've tried flashing a recovery.tar file as it's been suggested, as well as things like firewall and Usb cables but nothing seems to work. Literally nothing. Seems that being unable to get the phone into recovery mode at any point is the sole issues of all of these fixes.
Maybe someone with better knowledge can advise. I'm not bothered what happens to the phone, the photos/data on it are far more important but running out of hope to be honest.
