Well, I have a d2pad SN 201301 on the back so its somewhat new
It uses rk2829 rockchip.
Anyways Ive been trying to get recovery on it for the past couple hours to use a new rom, finally got recovery working, did everything installed my rom, and let it restart.
Well, The rom isnt compatible, there was a later version a few pages into the thread that might have been, but the one I got wasnt.
So now I'm stuck, at the intro d2 logo
I only have 1 button and it is power.
Ive tried to get adb working, because it at least says its connected, but with no success anyone have any ideas?

Hey, I realize that it's been a couple years since you posted this question. I never saw any responses. So how did it all end?
Also, there was one critical piece of information you failed to share with the XDA community...you said you worked on getting into recovery with a device that only had a power button and no volume buttons. May I ask how on earth you managed to get into recovery using only a power button? Reason I ask is that I am now facing this situation. NTech Alexis RX3HD8 tablet, rockchip RK2928 processor, power button and no volume buttons! I need to get into recovery but I cannot turn on USB debugging (and the tablet is pattern locked but the pattern was entered too many times....so I am locked out).
At this point, if I cannot enter recovery mode, the tablet is a permanently soft-bricked which is, for all intents and purposes, the same as a hard-brick.
I think what happened for me was, wanted to install new rom, got into recovery to install it, then it bricked my tab, after that I was at the logo
in my case i fixed everything by getting a rkflasher, to reinstall it, and contacting support for the factory image, which is lucky they new something about it, some companies abandon support, or dont know enoguh about what they sell, lol
as for your situation
these are the things i'd try
1. If it has google play, and is connected wifi even if its locked you can try this page
https://www.google.com/android/devicemanager
and then pick ur device and factory reset it is an option (although ive never tried it)
2. search around on the internet for 1 button recovery methods, I've seen quite a few weird tablets, and some I can think of with 1 button recovery
A. a pin hole thats not the reset button or the mic, was an actual button, and that was used to get into recovery with a safety pin, and doing the normal holding it while powering on method
B.. holding the power button, and instead of letting go when u see a logo, keep holding it, till it shuts off again, then power it on
C. plug it in to pc via usb, and turn it on, while its booting, see if ur pc recognizes it at any point during the startup and try to run some commands, ive had a brand of tabs, that give u adb access during boot, but then remove it after finished booting
4. their website is in spanish, and they dont have firmware/manual links available for your tablet
You could contact support for recovery instructions or reflash instructions,, and hope they speak english or you speak Spanish
Most of the time with 1 button tablets, if theirs no info of similar ones online, unless you can contact support, you might be out of luck
PS, my edit:
also, I saw ur post on the youtube video while looking up stuff about this tablet, if that guy can get you a firmware, you have another option of trying to get to download mode too
my tablet, with rk2928 uses these instructions to get it to show up in the RKBatchTool.
https://www.d2pad.info/docs/OSFirmwareInstallInstruction_D2-721.pdf
maybe they can help you get into download mode on urs
all of this being said, I hope my first suggestion will work, IDK if wifi is disabled during pattern lock, or if u can factory reset any tablet, I just know I always see that option when I'm using it to find my devices ect.

Without ADB a soft-brick can become permanent state!

Hey thanks for getting back to me. You've been extremely helpful and your response may hopefully be found in future by others who have the same problem.
Here's how it's working out for me with this device:
1. It has Google Play but unfortunately the wifi is turned off and there's no way to connect. But in any event, the little kid whose tablet it is (I'm working on the tablet at the request of her father who is my friend), she doesn't remember the Gmail account name or password.
2. I've searched the entire Internet (LOL) including Spanish and Chinese websites/videos but no luck. I can't find anything about putting this badboy into recovery. The reset button is just for show...it only turns the tablet off in case the power button is unresponsive.
3. I've been to the website of "manufacturer". It's a Portuguese company (I speak the language) but they haven't responded to any contact requests. And they appear to offer the firmware for the devices but download link is dead. So I cannot even get the firmware to flash it. The dude on YouTube has not sent me any link to firmware.
But the bigger problem and the key to the issue is that I cannot get the tablet to be recognized by the computer no matter what I've tried. I've tried all kinds of combinations of power button play but I never get that satisfying BEEP that indicates that there is a connection open. You see, I have the drivers for the tablet but there is no way to install them without the tablet giving the opening (even if it would come back as Unknown Device). So, I'm crap out of luck with this soft-brick.
Again, thanks for your help. After 3 days and probably 15 hours spent trying to reset this thing, I'm going to have to throw in the towel. Important lessons learned:
#1. NEVER PURCHASE AN ANDROID DEVICE THAT HAS NO VOLUME KEYS (or without knowing how to get into recovery). You're only asking for trouble if anything should go wrong. And believe me, this is the THIRD TIME I've seen a device that cannot go into recovery. In one case, I was able to flash new firmware directly on bootup off the external SD card (it was an Android laptop with WM8505 chip). I guess one out of three ain't bad odds...but they are not the kind of odds you want with expensive devices.
#2. ALWAYS TURN ON USB DEBUGGING WITH ANY ANDROID DEVICE YOU OWN AND TELL YOUR FRIENDS TO DO THE SAME. One day, it may end up being the savior of the life of that device because it usually means you can access the device via ADB in case of a soft-brick. LOL.

At last, did we find at last how to enter in recovery mode if there is only one button (power). I am in the same situation with @CVAngelo .Is it possible not to exist recovery mode at all? My tablet is BENEVE R708G with Rockchip RK2928. I tried every combination with power button and reset button but no luck at all.I have boot loop after trying to change the bootanimation.The weird thing is that the new boot animation ''works'' but after that it goes on boot loop forever.
Hello,
I have a Samsung Galaxy S2.
After reading this post http://forum.xda-developers.com/showthread.php?t=2382579 I decided to root my phone.
So I went ahead and started with this step http://forum.xda-developers.com/showthread.php?t=1118693 because I was unsure if I had a kernel with the MMC-SUPERBRICK-BUG.
After I flashed CWM-SuperSU-v0.97.zip using Odin version 1.85 and after the phone rebooted it was stuck at the "triangle screen" for a few seconds then the display went black and I couldn't do anything further.
Up to this point the phone was still accessible in download mode (volume up, power and center button). I believe this is called "download mode". Sorry but I am a complete noob with rooting phones, etc...
So I panicked and took the phone to a repair shop (big mistake). The guy ran it in download mode then tried to flash something onto the phone (I think he used all 4 fields: Bootloader, PDA, Phone and CSC.
Then, in the middle of the operation, Odin froze when writing "setting up connection". Then the phone died ! pressing the 3 famous buttons does nothing and the phone just stays dead.
I had to leave the phone there as the guy said they will try to bypass stuff and try to connect to the CPU directly (sorry again if this sounds noobish). I did update my modem firmware and my computer BIOS in the past... but I guess this one was more complicated.
At the shop, they asked me to check again in 3 days. I am lost here. I don't know what to do anymore.
Is the phone hard bricked ? Should they bear all expenses for what they did ? I would bring back my phone and try something like this http://forum.xda-developers.com/showthread.php?t=1878255 or even a stock flash but I am afraid I cannot do that as the phone isn't even powering up anymore after they tried to repair it at the shop.
Any advice is appreciated.
Nope. You borked it. You tried to flash custom firmware to the phone & obviously failed spectacularly at it. Instead of trying to flash it yourself via download mode (which you could easily have done unless the NAND was borked), you paid them to do it. Sometimes flashes go bad. Sounds like that's what happened in this case.
Reading between the lines they sound like they're going to try & JTAG it (or have someone else do it). And if that fails I presume they'll change motherboards. You could always get the phone back & take it to someone who does JTAGs if that shop doesn't themselves.

Yes I know I failed at it
Or maybe the shop technician is the one who broke it. At least when I had the phone with me I was still able to boot in Odin mode.
Do you think I could have recovered my phone if I had kept it with me and it was booting in download mode ?
I feel so pissed that I took it to that shop. I just wish I hadn't panicked and I had tried, instead, to fix it at home by asking for more help.
Anyway I still haven't paid them anything so far.
We agreed that they will pay for the motherboard because I brought in a working phone (that would power up at least). The owner of the shop was nice enough to agree that he would only charge me fees for installing new software on the phone (even if they have to change the motherboard) because he knows the phone was booting in Odin mode when I came in to the shop and his technician flashed the wrong firmware.
I also wrote down the board serial number so I can be sure they changed it (if they say they did that). So you are telling me the phone can still be fixed ? What does JTAG mean ?
Even if it is fixed I think I will be too scared to try and root it again. Unless I can understand in advance, step by step, what I need to do and what file version(s) I need to use.
Ok, I got my phone today in good working condition.
According to the shop, they had to replace an IC (I don't know what damaged the IC, I am assuming this happened when they tried to electrically jolt the phone) then JTAG it to get it to work again. They charged me a small fee (and they did end up bearing more than 50% of the expenses) because I brought in a phone that was booting in download mode and they take responsibility for what happened after that (flashing wrong files which caused the phone to completely stop booting).
Anyway, long story short, this was my first attempt to root a mobile phone and I learned my lesson.
I am running the following:
Model Number: GT-I9100
Android Version: 4.0.3 (which I will need to upgrade to 4.1.2 of course)
Baseband Version: I9100XXLPW
I know you will say read the sticky posts or the guides but the truth is, that's exactly what I did (you can see the links to the guide I tried to follow in my original post) and I still ended up failing at rooting/installing cyanogen on my phone right after installing Clockwork Mod.
The truth is I am scared to try again and mess up the phone. So this time I would rather be safe than sorry.
What can I do, this time, to safely root it and install a mod like Cyanogen.
Detailed steps are appreciated:
- Do I need to upgrade to 4.1.2 before rooting as 4.0.3 might have the superbrick bug ?
- How to backup the phone.
- Odin version to use, ClockWork Mod version to use, Cyanogen version to use
- How to connect the phone, how to reboot in download mode and all the necessary actions to avoid bricking my phone.
No spoon feeding aloud on XDA.better to read and learn how to do this and that but before you flash anything after learning how to do that learn how to fix it if it doesn't work. :thumbup:

Fair enough, I figured I'd get that reply from someone and it's normal to be honest.
I decided not to try anything on my phone before I re-read the guides and be sure I know what I am doing.
I will also keep the phone running on stock firmware (after upgrading to JB 4.1.2) to check the battery consumption behavior which, I hope, will be fine since someone tampered with my phone's electronic components at the shop.
Hey, so I've looked through these forums, as well as google search, with every combination of words i could think of to address my issue, and so far nothing has worked. So im posting here, hoping y'all can help me.
My phone is the Lg optimus L9 p769 running FW v20h. I had it rooted, bootstrapped cwm recovery is installed and still accessible. Unfortunately for me, i had disabled usb debugging off. Cant remember why, but I did.
I was browsing around for build.prop tweaks, found a good list, and implemented a few. After reboot, everything was going smoothly, hell, faster and smoother than before, which i assume came from tweaking the build.prop. At that point, i chose to implement 1 more and be done. So i added the line and rebooted my phone. SOFT BRICK!!!!!
Now, as i said, ive done quite a bit of searching for a fix, including the offline fix and basic LG Support Tool restoration, but nothing is working. Offline fix says my phone is not connected. Online recovery says im already at the most recent FW available. Ive tried fastboot, but installing the u boot and x loader wont work. CMD doesnt recognize my phone when i try anything adb related (obviously, because usb debugging isnt enabled), nor does it recognize my phone as a fastboot device even with the phone displaying the mirrored logo and says fastboot v0.5 in the top right corner. Also, the bootstrap CWM wont mount my external SD, which has my build.prop backup on it.
So, basically, that what I've read into. A wall, so to speak. As a side note, my wife has the same phone with an unmodified build.prop. in fact, the only thing that i have done to hers is root it with the LGpwn app.
Now, is there anything i can do with this, other than throwing it against the pavement outside? While i think I'd get a sick satisfaction from that, it hardly solves my problem. Also, i called LG directly, but they won't help me at all without payment. Even with their CS rep saying it was their fault (because, of course, I'm not dumb enough to tell them I broke it by messing with the build.prop). However, the slight bit they did do remotely through the laptop had them going through the LG Service Tool.
Anyway, that's about it. It really is a great phone and i really would like to repair, rather than replace, it, but im stuck. Anyone got any ideas?
Hello,
I had a similar problem, offline method didnt worked for me saying that my device is not connected. Then I faund this tool on forum http://forum.xda-developers.com/showthread.php?t=2797190
Use it with described tutorial (use 3GQCT and DIAG) and you are going to unbrick your phone.
Ok, I'll give it a try when i have access to the neighbors laptop again. I'll post the results here. Fingers crossed, my phone is up and running again soon and I'll be able to post my results from my unbricked phone.
IT WORKED!!!!!
Holy hell, it worked! A week of searching and trying with no success, now my phone is up and running again! Thank you sooooooooooooo much! Can i get a solved tag?
You're welcome. I'm glad I could help
Hey guys, please forgive me for any bad etiquette or lack of information (any information I can provide is available upon request if I leave anything out). I am new to forums in general and especially to XDA, which seems like a good place to get help.
I recently purchased a Sony Xperia Z2 Tablet from Craigslist under the assumption it was a fully unlocked tablet not associated to a carrier. Turns out it was a Verizon Z2 tablet. I dislike Verizon with a firey passion and without getting into too many details, I'm fairly certain they won't help me because a) this tablet wasn't purchased through them as a customer and b) Verizon and I have bad history (unauthorized account modification, shady charges, etc.)
So I thought I'd do my best to make the tablet mine since the asshole who sold it to me has ceased all contact and I don't know how to get a hold of him anymore. No receipt and a data-less tablet.
Anyway, I successfully rooted the tablet and began installing apps that I installed for my G4 when I rooted it (SuperSU, Adaway, Greenify, etc.)
Things were going well but I realised I wanted anything that had to do with Verizon removed from the tablet so I was going to flash Cyanogenmod onto it with a guide I found online. Now rooting and installing custom recoveries was familiar territory and I did these flawlessly. It had TWRP and I made a backup of the system -no Nandroid, sadly-and I began the flashing process. The process said it completed without issue and I went to reboot my device. Enter my current situation:
The device, when I attempted to turn it on, all it did was vibrate constantly until I let go of the power button. Attempting to enter recovery mode (green LED, power + vol down) it showed me, instead of TWRP, a very basic recovery mode with basic options. "Continue booting up", "enter safe mode", "system recovery", and "power down". I tried entering safe mode and it just shut back down, I tried doing a system recovery and it shut down. The only time I ever see the "SONY" logo is if I'm entering this mode. I can enter what I assume is "fastboot mode" (power + vol up and plugging the device into a PC). Nothing on the screen but the LED is blue. I am trying to find guides to restore it if I can and it all looks promising but the only things I know how to really do are root and install custom recovery. I know there are PC tools I can use to send commands to it while it's in fastboot, or send commands in general I just don't know where to begin.
Does anyone know how to fix this? I know it was from Verizon, which sucks, and I know the problem most likely occurred with the attempted flashing of Cyanogenmod. I think I read somewhere I might have done something regarding mismatching kernal numbers. I couldn't find a way to unlock the bootloader so I assume that had something to do with it too.
If someone could give me a guide to restore it to at least its stock ROM where I can begin rooting and installing a custom recovery again, that would be great. Even better would be just flashing a ROM on there that doesn't need Verizon or being able to take it to a stage where it's unlocked and the only evidence it was ever with a carrier is the Verizon logo on the back. I'd really hate to think I wasted money on this and now I'm at a dead end because of a mistake I made. This was supposed to be a gift for my mom on her birthday which is coming up soon. So if anyone knows anything, or has a guide where we can at least get the thing bootable again and I'll just try and deal with a rooted locked device, that would be great.
Thanks for considerations,

I have spent time on that screen too.
2 things
1. .. If you installed dual recovery, there is an up, down sequence to select the recovery.
2. Find a downgrade guide, use flashtool to flash. Ft back to stock.
Also you need to know what hardware you are running..511, 561.. And use the proper version.
There are some options with the flashtool and prf maker that can remove branding and vendor stuff. I have not tried those options.

Sorry if this is late... But where can I find the stock? I've searched everywhere and I would need to do it from a flash tool on my PC? I could use all the help I can get.
I just had a very similar experience to the OP, seemingly identical in every way, and am curious if anyone has a solution.
ADB won't function at all, and the bootloader has blocked any sort of flashing via fastboot. Can't boot into TWRP, it goes into a very minimal "recovery," which I imagine is the stock tool, and the Factory Restore option there does absolutely nothing. Flashtool would work great if ADB / Flashmode was at all functional (device blinks and vibrates in a fashion typical of something bricked, and no connection is picked up).
Verizon Z2 Tablets are 561s.
This thing dead or is there some way to push back onto it?
Hi guys, sorry if I posted this at the wrong place.
I have a Lenovo s860 and it went into a bootloop. It was stock and all so I thought that I can have my files recovered if I just bring it to a service center so they can get the files first before wiping it or maybe even fixing the bootloop without wiping the device. Well, the thing is, the guy at the service center screwed up and now, when I try to turn it on, I still see the boot screen (Lenovo, powered by Android) but the next screen is like an television with bad signal.
I'm familiar with rooting and flashing ROMs, I've tried it on my Galaxy S2 (yeah I know, it was way back), but I think things are still more or less the same: I need to be able to boot into recovery mode in order to root the device. However, when I tried the Power Button + Volume Up, or any combinations of the Power Button and the Volume Buttons, it just goes straight to the dead screen, I get no response whatsoever.
I also tried to check if adb can detect it, however, it didn't seem to be able to do so. I'm using a MacBook Pro so I know I don't have to install any drivers, I also code Android Apps so I have a background on this.
I think my only option would be to flash the ROM on this dead device but I don't know how to do that. I've also seen some posts that suggest doing some things (I forgot the specifics) while the battery is drained, so what I'm doing for the mean time is to leave the phone open and let it drain which might take ~2 days.
Does anyone know how to flash a ROM on a bricked device? Thanks for any leads.
