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.
Hi, I've been browsing the forums for people's attempts to fix a problem. At first the phone just turned off and I was unable to turn it on because it was stuck in a boot loop. The rom I had running was an ICS stock rom from hk. During this time i was still able to get into download mode but unable to enter recovery. I have tried many times to get to recovery and then tried to flash with several stock roms too. Upon failing around 10 times I moved on to a custom rom.
This one here:
http://forum.xda-developers.com/galaxy-s2/help/guide-26-12-flash-stock-firmware-rom-t2365701
The Jelly bean one here.
Upon failing from this too and unable to do anything but reset the phone and try again. I managed to turn it off... but now unable to turn it on in any way or get into download mode or recovery.
Is there anything I can try to do to get the phone to be working? What can I do?
Try a jig but understand it's very unlikely to get you into download mode. Service centre or local mobile repair shop for diagnosis (I also doubt it will be JTAG'able).
Edit - Also, search for KingRat's 'jump start' method where you try & boot the phone with just the charger/without the battery.

Don't loose hope mate...
Try remove battery and insert charger (optional)...
Press voldown+home+power button then let someone (your mother, father, brother, sister, neighbor or friends) insert the battery for you while still pressing those 3 keys...
I hope it will enter to download mode again...and report back please...
Try to use an other battery, my original one is fuked up, it does nothing.
I bought a new one and it works
I tried plugging my charger to the phone and pressing the 3 buttons and then having someone plug the battery in for me, still wouldn't start up. Also tried it with another battery i have on hand, also no luck.
You know what the options are then. Ignore people making ridiculous suggestions which don't work. My aim is to be honest with people, tell them the truth, and have them either get their phones fixed or replaced as quickly as possible in this situation (let's face it, nobody likes to be without a phone), rather than fill them with false hope & waste their time.
I think I fried my mobo while trying to flash it cause it does head up the phone without showing anything. I am going to order parts on ebay. I got this confirmed by someone at a shop near where I live, however they won't replace the mobo for me even if i do find a working one.
=) luckily this isn't my phone but my dad's who works at home and doesn't mind using an OLD OLD flip phone just for calls for the time being.
Side question, even if i replace the mobo and I get it booted but I still get stuck in the boot screen loop and unable to flash to any stock roms what can I do?
If you replace the motherboard you should fix it without further problems. New motherboard = new NAND, no more bootloop - unless you flash again & the flash is bad; you can't mitigate the risk of a bad flash, you can only do all the sensible things like making sure you're using a PC with reliable USB ports, that you're flashing the correct firmware for your device, that you're using an original Samsung USB cable. Basically, if you're careful, the risk with any given flash is very low.
So, fix the hardware problem, flash stock for your country/carrier once you've done that, and go from there.
Hi.
I'm new here so pardon any error...
someone advised me to post this problem here/ tterox
i was trying to unlock the network using a tutorial i found online.
but after editing the "mmcblk0p4" file the phone shuts down and won't come on. i tried plugging it to pc and it shows a "qhusb_dload" driver window. i tried using linux also and it shows it in qdl mode.
I don't know what to do because i''ve tried so many options adb and fastboot can't detect the phone. any useful information will be appreciated.
thanks.
Sorry to say but most every time that a device gets into Qualcomms download mode you have a brick. There are a few times that people have hit this mode momentarily and got out but I suspect that you were playing with a partition that is needed to boot thus cannot boot.
Usually the only thing to do know is JTAG or return to the factory for RMA
Sorry for the bad news

well, i read in a post that it was possible to push firmware to an android device in that mode...i tried it and i was able to view my partitions but i dont know how to reflash the hboot.
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.
Hello,
So I tried to flash a global rom into my chinese GT 2 pro which didn't actually work, and in the process of fixing this and having to go to work etc the phone battery died and now that I have all the resources to "unbrick" the phone I can't flash anything because of the low battery and I can't charge the phone because it won't even load the recovery mode. I am trying the .bat file that I found in this forum where it charges rebooting the fastboot mode but it's charging 2mv every 3.5 minutes and if my maths are correct, this would take me 2 months to charge to 30% in order to flash anything which obviously is not viable . And I've seen suggestions about splitting a cable and charging the battery with the wires directly but I can't find any information on how to actually do this. Would this work at all? Or is there anything I can do? Please give me some hope! Thank you all in advance
boot into TWRP from fastboot and let it charge
I have tried this but still not working. It's says OKAY after "sending boot" but nothing happens, just a black screen. Although I'm not completely sure that I'm doing this right or even using the right image. Would you be able to guide me with this a bit further please?
try this to disable start-up on usb
Code:
fastboot oem off-mode-charge 1
fastboot oem enable-charger-screen
Thank you, I will try this tomorrow and update either way in case it helps someone else (because hopefully it does work! )
Hello all, so those codes didn't work. I got a guy to try and unbrick it who in the attempt to do so he actually hard bricked it I had given up at this point but he didn't. He wanted to try a test point which involves opening the back of the phone, which actually worked! (Apparently we tried to flash the wrong ofp) anyway, in the process of opening the back case I damaged the power flex (and the actual back case too, but I wasn't too worried about that as I thought I had no phone anyway).... I would attempt to replace both but I can't find where to buy replacements. If I try to google it everything I find is for realme gt neo. Any ideas where I can find a new power flex and back cover? Thank you!
