[Q] [SOLVED] Off-brand tablet bricked after "adb reboot bootloader" - General Questions and Answers

Hi,
I have an iRulu (some off-brand Chinese tablet that is also somewhat branded as Allwinner) 9.7" tablet. I was going install a recovery and try to learn how to compile a ROM for it but things went wrong at step one. I hooked it up to my computer (running Arch linux) and got ADB to recognize the device. I typed "adb reboot bootloader" to get into fastboot and see if the bootloader was unlocked, but when it rebooted it just got stuck on the logo screen and was not responsive to fastboot and adb no longer recognized its presence. I haven't been able to find any other examples online of that command bricking a device. As far as I can tell, none of the normal button combinations work to get to recovery or anything like that. It's not really a bootloop because it doesn't restart and try to boot again. It's just frozen and I can't find my way in. I found a forum that said to disconnect the battery for 30 seconds but it's soldered in (I'm comfortable desoldering and resoldering but I'd prefer another solution). Any ideas on how to recover the situation? Thanks in advance!

When you open the back cover, do you see the board number? You can try searching for firmware using the number, and flashing it. Mine was stuck in bootloop for months before i figured it out(i own a ubislate 7c+ edge, a11 firmware worked for me).

Thanks that's a great idea. Might not solve the problem to know the firmware, but more information is always helpful.

OK, I solved this. Here's what I did:
- Let the tablet die. All the way. After I left it on that stupid boot screen it was stuck on until it died, I left it another week just sitting there.
- Plug in the power connector and the micro usb connector.
- Turn it on once it gets charged enough that it's willing to start.
- Move the USB connector to the USB-to-go (HOST) spot while still connected to your computer. This crashes the device from some kind of voltage protection mechanism.
I'm not sure exactly what happened but after that the device started just fine. I think the voltage protection mechanism might have kicked it out of "boot to bootloader" mode, where I think it was frozen, and into actual boot mode. I wouldn't necessarily recommend this solution since I put the actual hardware of my computer and the tablet at risk, but I figured my laptop was old and my tablet was bricked so there wouldn't be any huge loss.
Anyway, I'm marking this as solved. If anyone has this happen to them and my solution actually works for you, let me know. I'd get a huge kick out of hearing someone else follow my stupidity. Good to have my tablet back!

Sisonke= We are on the same path in my language
i am currently having the same situation RIGHT NOW. Loved messing with ADB and its ....functions... also typed adb reboot-bootloader and guess what i got.. Stuck at the boot face. lol:laugh: but im gonna take our advice, if you say draining the power is the key...well i find no harm in cutting the main battery source for a while and then reconnecting it again. If this procedure doesn't work...I'll have to do it your way. Crossing fingers ..hope it works. email me wen u get this. [email protected]:angel:

[Q] Dead touchscreen

Hello,
I am trying to fix my girlfriends HTC One S, she accidentally dropped it into the bathtub full of water, she picked it up fast, put it to rice so it sucks out the water and applied heat, the phone worked, but the touchscreen is totally unresponsive, is there any way how I could determine if the touchscreen is damaged, or the motherboard? I dont have anyone else around me who would give up their warranty and let me open theirs phone so I could test it. I already disassembled the phone, tried unplugging the connectors, checking if there is any visible water damage, but i got nothing, so either the panel or the motherboard must be damaged, I need some way to determine which one is it.
I will also add a conversation with Awesome, he was trying to help me at first and there are some more information.
The wet phone? I did reply. Is the phone rooted? If its not boot into the boot loader holding the volume down and power and click factory reset see if you get the touchscreen working again. If it doesn't work then you short circuit something but if it works and goes away then its your screen.
If your phone is rooted its gonna be hard to do factory reset.

Then I probably did not figure out the answer was for me
Well, the problem with that is, that there are some valuable photos inside and a factory reset would definitely remove them,
I was looking for a solution for backing them up, I got to a software, that can control the phone from PC without the need of being
installed in the phone, there was a slight problem since it required USB debugging to be turned on and it wasn't. So I was browsing
the internet to find out if it is possible to turn on USB debugging from PC, or perhaps somehow, until here on XDA in some thread
someone said it is impossible, so I gave up backing up the data and went straight for the repair, that is why I need somehow to find out
if either motherboard is damaged or digitizer, I have the phone totally disassembled. I am guessing that some touch controller on board is
damaged, since I cant see any visible damage to digitizer, but I am not sure and I do not want to buy wrong part.
Also the phone is not rooted and is using stock ROM.
Thank you
Yes without USB Debuggin its impossible to extract those files, and without u doing a factory reset I really can't think of doing or trying anything else to figure out what may be the problem. Since its water damage you really won't see if its short circuited. I'm more than sure you got a short circuit rather than needing a digitizer. Other than that feel free to open a new thread in the general section of the one s and asking there maybe other users will have other options for you.
Thank you for help.

Em so is the bootloader unlocked? you could try to see if adb is working in fastboot or if it is unlocked I think TWRP lets you use adb.
Well, its all in stock, so I guess the bootloader is locked, and without USB debugging turned on ADB doesn't recognize the phone.

Ok but have you tried adb in fastboot?
adb in fastboot should work, regardless of the setting in the rom.
What android version is it running? If its running 4.1 you could use an OTG cable and hook up a mouse to control the device.

Theres also an app that can share your kb/mouse to your android device, the device will see the kb/mouse as hardware plugged in.
ShareKM its called, works damn good on both my S and TF.

Cool think I have a play later.
Okay, here is what I got, the OTG cable is not working, that means the phone doesn't have Android 4.1.
The ShareKM application requires installation into the phone, meaning it is out of question too.
I am experimenting with this ADB in fastboot, but I am not really sure how that fastboot command works when I run ADB.exe trough command prompt and list devices, it show me only my other phone in USB debugging, when I run the fastboot.exe and type adb devices it says "waiting for the device", I do not really know how to work with this with a little guide, it shows me some commands there, i tried the one with rebooting into bootloader, but it still says only "waiting for device".
Could you give me a little guide perhaps link to guide what exactly I am supposed to do to run ADB in fastboot?
I am pretty technical type, dont need noobish explanation.
Thank you
Okay, I managed to get into fastboot, I always thought it is something with the fastboot.exe in SDK Platform-tools, well, anyway, I am inside, it says Fastboot USB, but adb still isnt showing the device in the list.
Also there is a big pink ***LOCKED***, that means that bootloader is locked I guess.
Any other ideas how I could backup the files? or any other suggestions?
Thank you
Moving slowly forward, I was being stupid and I was using the ADB command instead fastboot command, when I am in fastboot mode now, well, trough fastboot command now the PC recognizes the phone, altho what is the next step now?
Thanks again
Yeah, the ShareKM app was never really ment for you, it was more of a suggestion to dark sorry if it confused you.
I ran some quick tests, and yeah Im afraid adb is, in fact, not working in bootloader.
What happens if you boot into recovery? Maybe it works there?
What kind of things do you need to save? Is it just like pictures and stuff from the sdcard?
In that case, you could unlock the bootloader (this will wipe the device data, like applications etc) and install TWRP. Im 100% sure ADB works in TWRP without you needing to use the screen.
Just tried booting into recovery, the only thing I am receiving is big red exclamation mark, not sure what it means, I did some digging and it usually appears when someone is trying to do OTA update from custom ROM, strangely, this is original stock ROM.
One S doesn't posses SD card, it has 16Gb internal storage, but is probably divided into some system partition and data partition, if that is what you meant. Yes, it is only some photos and videos.
You said TWRP, as I did some background search, it says touch recovery, that kinda sounds it uses touch, and that is the one thing I can't use.
Or am I mistaken?

Right you say adb is see your phone now, download Quick ADB Pusher load it and see if you find the sd card if it does just copy over everything you want, it will need to be in pull mode for this.

It did not work, but I am going to describe everything I did: I started the phone, got into Bootloader, switched into fastboot and connected USB cable, then I started the Quick ADB pusher, switched into pull mode, opened ADB Explorer, but there I dont see anything, only "error: device not found".
Did I do anything wrong, or is it that the Quick ADB pusher doesn't work in fastboot?

Then I'm out of ideas because unlocking the Bootloader will wipe the sd.
Indeed, Quick ADB is just a GUI front-end for adb commands. If adb doesnt work in a command line, Quick ADB wont work either.
Theres nothing I can do about that, its not like I can magically force your device into accepting adb commands.
Unlocking the bootloader wont wipe the SD... At least, it didnt for me (just the /Android/ folder).
Things like pictures taken and custom ringtones were still present after the unlocking.
So, ADB doesnt work when youre in recovery either? (the big red exclamation mark)

And I am not throwing any blame either, I am just open to every solution
How would unlocking the bootloader help me? so I could put that TWRP inside and do some magic with it?
For the recovery part, I am not really sure how it is supposed to work, but every picture I googled shows some text
along with the exclamation mark, but the only thing I am getting is exclamation mark, and after a while the phone reboots.
I am guessing the recovery either wont load up, or something is wrong, should I try running ADB while that exclamation mark is shown?

[Q] Hard Bricked my Nexus, possibly?

After flashing a nightly of CM10.2, my phone never booted and instead got stuck in fastboot. My power button has also been broken for months, so it's impossible to navigate the menus in the fastboot ui. When I take my battery out, it automatically boots into fastboot on its own.
Additionally, I found a way to boot into recovery without a power button, but the device is not being recognized as plugged in by my computer.
Any help??? It'd be greatly appreciated, I'm without a phone until I can find a way to fix this.

I'm having the same exact issue, except with SlimBean 4.3. My phone is stuck in Fastboot (and says "FASTBOOT - NO BOOT OR RECOVERY IMG") and my phone will charge but can't be detected by *any* computer. I've tried three Windows 7 PCs of different makes and an Ubuntu 13.04 box and three different USB cables that all connect my other phone and my tablet fine - none can see it. (It was connecting fine to PC including being seen by ADB prior to this)
My power button is working, but it is also automatically booting into fastboot on its own when I plug it into the computer. Any of the options (besides "Power Off", which performs as advertised) just brings it back to Fastboot.
When I say can't be detected by a computer, I mean there is no USBDeview device listed and there is no 'connect' or 'disconnect' sound on the PC. ADB can't see it.
Yeah, it's strange. Did you find a solution yet, by chance?

Nothing yet. Thinking of buying an phone with a busted screen or something and swapping out the internals... I think it's PROBABLY the NAND chip. What I'm suspecting is that because there are several versions of the Nexus S, we might have used the wrong images. I have no idea if this is correct, but it's the only thing I can think of.
My phone's sticker says i9020 on the inside, but D720 (or whatever) when I look up the EIN.
Just hoping somebody sees this and offers a suggestion... I'm getting ready to buy a refurb and put the 'new' body over it so at least I have a functioning, new-ish phone.

[Q] I accidentally everything (TWRP)

Basically I was using TWRP to wipe my TF700T and I wiped the OS. Luckily I made a recovery on my SD, but the problem is that I can't get it to boot back into TWRP in order to run it. All the Power + Volume Down does is just cause the device to rumble. Powering on the device just lets it sit in the bootscreen. If I can get into the bootloader I can basically fix the machine. Problem I have remaining is that I can't seem to get into the bootloader.
The device calls itself APX when plugged into my computer now, if that means anything. I'm gonna try to drain the battery by leaving it on over night without the flash card. Maybe that'll do something.
Any suggestions on how to unbrick this thing? Or did I just succeed in turning a very expensive tablet into a very expensive paperweight?

Im having exactly the same problem, did you find a solution to this?
So far no results yet. I tried hitting the reset button on the side but all that did was lead me back to the boot screen. I read something about undoing the the hard boot using a series of override programs. But the problem is the documentation is so cluttered that I can't fathom the instructions (I'll try it again just in case.)
Bump update: So I called Asus and it turns out it's gonna cost 288$ to get the thing fixed by them. So I'm not doing that. I'm looking into other ways of recovery. I've got other multiple options I'm exploring at the moment. Like looking for a recycling program or a way to use the technology in a new way.
UPDATE X2
So I talked to a friend and the very fact that it sits at APX was a tipoff. Basically it means the recovery is shot but the Bootloader is OK. Meaning that the device isn't as bricked as I thought. What needs to be done is to download the android ADT bundle (google it) and from there get into the platform tools under command prompt, type "adb" then "adb devices" and finally "adb reboot recovery"
if it works the recovery should reflash and then using the backup restore the OS.
Granted I'm having trouble getting my comptuer to say "APX has been connected" due to a faulty data cable but I should be home free after this

Unfortunately if you can only get to APX mode and you don't have nvflash specific blobs for your device you are hard bricked...
Luckily I make a recovery file in my SD card wayy back when I did my first Cromi mod. It should still work if the forced recovery restores TWRP. Otherwise, yes, I might be hard bricked.
My friend, however, thinks there might be another way to force a OS past this block though. I'll have to see how this plays out.

Sorry it really doesn't look good, Maybe i can corrected but the device will fallback to APX mode if the bootloader is corrupted, without a bootloader you cant install/fix a recovery and without NvFlash blobs you cant fix the bootloader. Your two options are buy a new motherboard and replace it yourself or send it in for repair with Asus

As JTR says I'm pretty sure you can't fix this without replacing the hardware now. I don't think your friend really understands what APX mode is. YOu can't access the bootloader nor recovery. Without NVflash backup blobs you can't recover anything, there is no way to get your TWRP backups back on to the device and even if you could you have no working bootloader......

[Q] CWM on new Blu Life Play

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.

[Q] Tried installing Drivers for Shield Tablet, is it bricked?

All I want to do is root this thing, and after spending the better part of a day updating firmware, it seems I screwed the pooch doing that first.
I tried my best to follow the outdated tutorials, first step of each sent me onto another tutorial, etc. So I had device manager up, I sent it to look for the Universal Naked Driver, it said I was up to date, plugged along. Mini ADB and fastboot went up, my shield was in dev debug mode. ADB reboot command fails, and now my tablet won't power up with the hard key, and the computer wont recognize it.
Are there any solutions to this problem?
If the tablet doesn't power up maybe u have to send it to nvidia. [emoji20]

Seems quite strange that it would get bricked since you seem to have not done any operations to the tablet at all. Did you try to flash anything while in adb or fastboot? Are you holding down the power button long enough to power on? You need to hold that mushy button for what might seem like forever. There are tools like Win Droid that do what you're trying to do.
But yes, seems like you might need to send it in if the tablet is actually bricked.

And everything worked fine.

That was the one I started with, but I had to follow the breadcrumbs through the separate tool threads.
I factory reset the device before beginning this process, I hadn't entrenched myself in the tablet since I've only had it since last Thursday. Doubt that has bearing.
I'd noticed software issues, freezing in and out of the lock screen. This was high among the reasons I decided to root it. Its possible I got a lemon, and if I didn't muck up the bootloader its still under factory warranty, correct? Should I contact Amazon who I bought it from before contacting Nvidia?
If it doesn't turn on maybe it as nothing to do with unlocking the bootloader.
Just activate the waranty.
I charged it overnight, and turned it on via recovery (down volume and power). It seems to be running fine now. Thanks for the advice, and I'll continue the process in the appropriate threads.
:good:
