Hello all,
Recently I have had a major issue with my nexus 7. About a week ago, it died (ran out of battery) while I was using it. When I attempted to turn it on after charging it, I would get the screen that says google, with unlocked lock icon. The tablet would be frozen at this screen. I left it running until it died again. I was running the latest stable release of cyanogenmod 10 with no problems before when this happened.
By now I had realized that the nexus may have been bricked. I did some googling and found that this is an issue other users have been having when their battery died on android 4.2.2. I attempted to restore the nexus. At this time I was able to access bootloader on the device by holding down all of the buttons at the same time. However, I decided not to restore the nexus, and wait until a time where I would be able to turn all of my attention to the problem. But when I tried to restore the device yesterday, I was not able to access bootloader! I connected the device to my PC (running win8) and it is not recognized. Similarly, trying fastboot restart-bootloader gives me "waiting for device". I am afraid that the bootloader may have been corrupted somehow.
My question is, how can I fix this? Is there a way to reflash the bootloader, or is there something that I am missing? Is there a hardware operation that needs to be performed on the device (battery pull, etc)?
Thanks.
i seem to have this issue as well i cant got any response out of my N7 at all no matter what i do my problem was i was restoring stock image thou N7 toolkit on XDA and it decided it was gonna stop half way thou the install (died Completely even while on charge its dead ) and now i cant get no life out off it at all... iv tryed hard reset soft reset and even taken the battery out tryed getting into bootloader as well with no luck this is my 2nd N7 and they wont take it bk????? if some one could be able to help me with this as im about ready to sell it as spars n repairs which i dont want to but im sure some one will have it any help will be appreciated
thx mike

Hi everyone, I'm a new member to the forum, but have been a follower for quite some time.
Let's start by introducing my device wich is:
EEEPad Transformer TF101G with ICS running the latest WW_9.2.2.6 firmware.
The device is rooted and running ASUS stock recovery.
Everything was working fine until I decided to do a Cold Boot.
It got stuck on the cold boot menu for like 3 hours and I decided to turn it off.
After that it got stuck on the inicial Asus splash screen. I forced it to turn off a couple a times and it eventually booted up.
I knew something wasn't right, so I backed up all my files and applications.
Then decided to do a factory reset through POWER + VOL-
After that it never booted again, and after a few seconds on the splash screen I hear a click noise, like the hard drive is turning off.
When I try force it to turn off, it starts up again automatically.
I've tried to flash it through nvflash, but being a TF101G it also means it is sbkv3, wich is not supported by nvflash.
Also tried boot recovery tools, but it won't even start, because as I try to connect it to the computer through adb mode, after that "click" noise, the device becomes disconnected.
I didn't try any dangerous applications and stuff like that, just decided to do a simple cold boot, the device is a week old.
If I'm posting this in the wrong section I apologize.
And hope someone can come up with a good idea.
Thanks in advance.
Obviously somethings corrupted and in my opinion the only way to fix it would be to reflash the rom in apx mode using nvflash but that doesn't seem to be possible for your device as of yet but if everything is still stock maybe you can unroot the device (or play dumb) and get it replaced under warranty?
I don't think I can unroot it, since it won't run abd mode.
I'm trying to find a way of not having to send it to warranty.
Saving it as a last resort...

Eek.. since it was factory resetted I think you need to send it to warranty. Not much we can do now with just a splash screen on sbkv3
I don't consider myself an advanced user.
But I really did search everywhere and I got the idea that only with APX and without a compatible NVFlash I was screwed.
But I still had some hope.
Do you think they will give me trouble because of it being rooted?
I my opinion I don't think they will ever know, because It won't boot, It won't run recovery mode (stock) and nothing else at all, the only way to fix it is to flash it, but maybe I'm just being naive.
I treated it with all the care in the world, so only by divine intervention it is a hardware problem.
But you never now...
you should be ok (should)......
i done pretty much the same thing to a customers TF and Asus fixed it no problem.
The fact is that I actually didn't do anything wrong.
Just a cold boot that didn't work, followed by a a factory reset...
How long did it take for yours to get fixed?
Hi all,
First time posting on here (but I read the forums often - for guides etc).
Bought the Nexus 4 and I unlocked the bootloader and rooted the device. Kept to the stock Android (JB 4.2) however I locked the bootloader again.
The boot loop occurred after a restart after I did the following things:
1. Used Battery Calibration to calibrate the battery. Left the battery to drain and then charge to 100%.
2. Used VM Heap to change the amount and restarted the phone. Boot loop ocurred.
I have tried many things after reading this forums and other forums but there seems to be no answer to this issue.
Things I've tried are:
1. Booted into recovery mode and wipe data/factory reset many times - still has boot loop
2. Used Nexus Root Toolkit and tried the various functions on there. Fastboot doesn't detect the device (even though its in fastboot mode) in order for me to unlock the bootloader again and flash it with the stock ROM. Windows (8) does detect it but can't load drivers for it. Been through all the instructions on the Nexus Root Toolkit - reinstall drivers, cleared the device from device manager, cleared it from usb list etc. Fastboot just won't detect it to allow me to unlock!!
3. Let the battery drained and tried factory resetting but doesn't work (not tried fully charging it and then resetting though)
4. Been trying various other things which I read on the forum(s) but nothing seems to work!:crying:
Literally spent the whole day trying so many different things. Seems like I discovered a whole new unique problem to causing boot loop on the Nexus 4. I don't want to have to send this back to Google for a replacement if they give me one - hopefully with the locked bootloader and the data cleared, they won't know I've rooted, not to mention its micro-sim and my backup feature phone doesn't take micro-sim :crying:
Has any one had this issue before and fixed it!? Would really appreciate the help/guidance!
My first time rooting a phone, didn't do it before on other phones because thought knowing my luck I'd brick it beyond repair! Luck would have it, that exactly what has happened.
Appreciate the replies and help on this!

I'm having the same problem!
For the toolkit to see the device, you need to put your device to fastboot mode by pressing vol (-) and then the power button (the phone should be in powered off mode to do this).

I had a boot loop issue. It was stuck on Google logo - the white logo.
I couldn't go into recovery either.
My fix was to flash the stock recovery.IMG
I too couldn't detect the device however I kept trying.
If you face a problem getting into fast boot mode try pressing vol up + vil down + power. Didn't work for me but worked for some.
Let me know how it goes I'm glad to help out if I can
Having USB Debugging ticked WHILE IN ANDROID has absolutely no effect on whether or not your computer can see the device WHILE IN RECOVERY OR FASTBOOT.

Didn't fix it in the end...no matter what I tried. I got a replacement from Google (thankfully they didn't charge me for the new one!).
BTW the batch of Nexus 4 released in end of Jan/early Feb has a much better battery life than the one I got from the batch released in early Dec. Won't be rooting the new Nexus 4 in case sh*t happens again but no doubt will get tempted again somewhere down the line!
Thank you to everyone who replied!~ :good:
sideloading 4.4.2 and stuck on boot loop

all you got to do is download the toolkit and flash the software your phone is using and put it in fastboot and begin

Hi,
i never touched my Nexus 7 with any other ROMs or such. It was still rooted and kinda original. Now i can't do anything with it anymore.
I talked to the google hotline already and i was trying to start the bootloader which works fine, but nothing more.
1. When i choose Start, Restart Bootloader, Recovery Mode oder Power Off nothing happens, beside Booting failed (Recovery Mode).
2. When i start the phone just with the power button i just see the google logo.
3. When i plugin the power cable i don't see the battery for loading.
I got another device from google with horrorable battery power, so now i wanna try on my own the save my Tablet. I flashed my Galaxy Nexus and HTC HD2 couple of times, so i'm not a 100% Noob.
I was already looking in like 10 threads i found about problems nearly like mine, but i don't got the golden clue yet, sry.
I hope you can help me please.

I encountered identical problem on an N7 (2012) 32gb and try everything that I know how and always get the message ADB not found. Finally I use Skipsoft ToolKit and use option #9 Download, Extract and Flash Google Factory Stock Rom and it works . My N7 was returned to stock with latest firmware.. Of course you will lose all data and still have to unlock and root again
I am not a techie so I cannot explain the details but only share my experience.
I hope it will work for you

If you can't see the white battery picture when plugging in the power cable, I suggest you use AC power, and if you are, try using a different USB Micro cable.
Hi all,
Yesterday my Jiayu S3 crashed and rebooted, after setting an alarm clock and using the Spotify app. However, it did not reboot into the OS as usual. It did not even show the Jiayu logo, but the phone vibrated (sign that it's booting), screen turned on, phone turned off again, repeating this cycle over and over (not the traditional bootloop as I know it). I was running a rom based on the original rom, with some slight modifications. This rom was running stable for more than a week. I know my way around Android, and am used to switching roms, flashing etc.
Right away, I checked the following things:
- Battery removal didn't help (I did not forget to put it in again ofcourse )
- Phone doesn't go into it's charging cycle when charger is connected
- I do NOT have access to recovery
- I can, however, access the boot menu (Volume up + power key, options: Normal boot, recovery, fastboot)
- I can get into fastboot mode (haven't tested ADB yet), that's the only thing that's still working
I tried to flash the original firmware using SP flashtool, and I am still able to upload firmware on the phone! I am sure that I'm using the correct ROM, and tried different PC's and drivers. Got a few succesful flashes, but still bootlooping.
I also had the idea that my battery was empty (didn't charge it overnight), and measured the battery at 3.52 V. So it was pretty empty but not that empty that it doesn't boot. In an effort to charge the phone, I left it bootlooping for an hour or so, and later on it turned out that it only drained the battery further, 2.99 V.
I didn't want to kill this battery so I did use 2 other batteries from an old Jiayu G4, which appear to work if you turn them around and hold them against the pins (note: I knew what I was doing here ). After a lot of Googling, and seeing a lot of generic "how to fix any brick" stuff I was not able to revive my phone again.
I still believe (and hope) that the error is on the software side of the phone. All the partitions should be ok and in working order according to SP flashtool.
Now this is where my knowledge stops and where (hopefully) your help comes in. What can be corrupted that I haven't checked yet? Do you guys have any suggestions to revive this "high-end" phone again? Once again, it did not happen because of bad flashing or something like that, it happened randomly when I was using the phone normally. I tried to be as accurate as possible (long story), but if there are any questions I'm happy to answer them.
Any suggestion is welcome!
Thanks in advance.

Anyone?

I am in need of serious help! I dropped my phone off a 2nd story, smashed the screen completely. So I took my wife's old stylo 2 plus (exact same phone) stuck my Sim and SD into it, registered through metro pcs, and it worked great.
I did software update because I was really excited (my old stylo 2 was rooted and had many problems along with being unable to update android software).
Update took about an hour, then said failed. After that it has been unable to boot up. I tried recovery mode, it offers to factory reset. Again reboots and stuck at logo screen. Says error device is corrupt, cannot be trusted, will not boot. I press power it says press power again to boot anyway. Restarts and sticks at logo screen. Device is basically untouched. No oem unlock, no debugging, no developer options, nothing has been touched ever, the phone is 100% stock. I even did factory reset before I started using the phone.
Can someone please help me at the least flash trip so I can fix this??
I am not new to this, but has been 5 years since I flashed anything. The problem is, is that it's still locked, and can't boot up. The phones bricked and never been touched!
If I can get twrp flashed I can go from there, I need a way to unlock it, or flash without unlocking.
Please help me I need my phone for work. I'd rather not switch back to an old smashed screen

You need to download the kdz(device firmware) and flash it in download mode using lg up.
Sorry for the super long delay. I did what you said, and was able to use my phone again in no time. Thank you very much!

Hey would you be able to tell me which firmware worked or possibly even a link. I am having issues with getting one to work on the lg stylo 2 plus using lg up.
