Hello ! I really need help at this moment, i don't know what to do ... Really !
My Nexus 7 was in CM10, but 1 week ago, my tablet runs out of battery (turned off completly).
I plugged in, turned it on, and it bootloop on the Google logo. I mean i see the google logo, turns off and go back to the google logo, endlessly....
I tried the recovery mod to go back to the stock software... But i get the android's robot laying on it's back with a red icon....
No ADB status, and i cannot install the drivers with the nexus root toolkit ...
I powered it off, unplugged, plugged it, and let it charge all the night, but i get the same problem.
So .... I opened the back, see if there's any problem with the battery, disconnected and reconnected the connector, nothing suspect ... Turned on, bootloop on the google logo, super ... :good:
From this, i tried this method from XDA how-manually-unbrick-restore-your-nexus-7-s-factory-state-windows (can't post URL Ha!)
And tadaaaa, that's working now, i can access to my nexus 7 with the 4.1.0 Android, but ... I cannot access to the network ( it's connected but i get a grey icon with these little arrows...) and the battery shows 0%. If unplugged, my tablet turns off... Also, number of notifications show "......" as stoped working.
Now, i have the ADB status, that's pretty good, so that i can install the 4.2.2 Android version with the nexus 7 root toolkit. During the installation, at the end (when the tablet bootloop on the nexus logo with the color) my tablet turned off (maybe runs out of battery or a problem ? Don't know ...) ...
I plugged in the wall charger (not the computer) and my tablet restarted. See the google logo, after the nexus logo, and restart, endlessly ...
Now i don't know what i have to do, i'm completely lost. Do you think i can do something last, or i have to return my Nexus ?
Sorry if it's confused at some time, i've not a good english.
Thank you in advance
I think you failed to attach your battery correctly. Try disconnecting an reconnecting the battery. Than power down the tablet(Power button for 10sec if turns back on press power and volume down and choose "Power off") Than recharge your tablet using(Charger is better than PC). Now try flashing or installing Android. Should work. Let me know if doesn't.

I've already did that! It's correctly attached ...
I think that everytime i tried to install a new OS, my tablet turns off because he runs out of battery, whereas i though i was due to an error .
I've retried the method i gave above, Third times.
It's working now in Android 4.1, but if i try to update, my nexus restart again and again ...
Very annoying because i can't access to the recovery mode --' ...

I do think so ... It's the original OS
Thank you jesus ! ^^
I've saved my nexus !
I post the solution:
You just have to follow the guide, named as "[HOW TO] MANUALLY UNBRICK / RESTORE YOUR NEXUS 7 TO IT'S FACTORY STATE (WINDOWS)" on this same website. (As i'm a new , i can't post URL at this time)
You must do the installation twice or more, because sometime, the nexus 7 reboot endlessly on the google logo, or on the nexus logo.
I needed to do this three times in a row to get a full and complete Android 4.1 working .
From that, i followed another guide. (because if i try to upgrade to the 4.2.2 OS, the nexus 7 is also blocked and i got a non stop reboot tablet)
Just go on google and type this "How to install cm10 jelly bean on the google nexus 7 using twrp recovery"
This is a youtube video that shows you how to download and install the Cyanogenmod10 in TWRP recovery mod.
(To access to the TWRP recovery mod, you can also use the Nexus 7 root toolkit by clicking on the Advanced button)
And voila, that's working now perfectly for me !
Hope this will help
Hi guys,
I did a research regarding my problem, found a couple of threads but none of them helped and I noticed my situation is a bit different from most users having this problem.
I live in Brazil, went on a trip to USA for 15 days, kept my SIM card and SD into the phone, just used it to access WiFi, watch videos, make a couple of Viber calls, send messages via WhatsApp, etc. Everything was fine, no problem at all.
Today, when I landed in Brazil, I turned on the phone, entered my pattern and since then my phone just displays that initial screen "Samsung Galaxy S4" and keeps rebooting like crazy. In these last 15 days, I didn't make a single change on the phone. Absolutely nothing. It just decided not to work anymore
My phone is not rooted, runs the latest updates.
I tried initializing in safe mode (power+home+volume up), it shows the android green robot at a glance and then reboots again. I can't even read what is written on the screen, so fast the reboot takes place. I also tried pressing the menu button repeatedly, but no luck as well. Tried removing the battery, turning on without SIM & SD, nothing. When I connect it to a power source, the red led doesn't even light. My computer doesn't recognize it either.
Any suggestions on what to do? Returning it to the shop is not an option as well, cause I bought it out of Brazil...
Thanks a lot, colleagues!

You could try this take the battery out for at least 12 hours , I read somewhere that can work for your kind of problem
I had this with Note 2.
No other option but to factory reset and flash official samsung firmware from sammobile.com
After that we were back to normal. Try that.
sounds not that bad..
try booting on download mode then flash some official firmware from sammobile.com
NOTE: don't flash XXUMH8 or any MH firmware for it contains new bootloaders with the samsung KNOX crap.
I really wish I could solve that without having to install everything again... but anyway
I'm sorry for this newbie question, but how can I flash a new firmware if my computer doesn't recognize my phone?
And what software do I need in order to do that?
Thanks a lot!
Just one more question...
if I really have to install a firmware, isn't it better to flash one from another country?
It seems like Brazil is always one of the latest to get the updates
Which country would you recommend?
Thanks a lot again, colleagues.

I'm totally sure it is genuine.
I mean, I can go to download mode.
When I press power+home+volume down, it works.
But when I click volume up in order to continue to download mode, the phone reboots.
It can't stay stable for more than 3 seconds, let's say.

Ok, but in order to perform a hard reset, I need to press power+home+volume up at the same time, right?
That doesn't work either.
When the small green android robot is shown, the phone immediately reboots. I can't even read if there's something written, so fast it reboots.
Are there any options left or just sending to Samsung?

Try removing your sd card before going to download mode, maybe it's trying to finish a failed update. Try using someone else's empty sd card

Rebooting issues are battery related sometimes. Try another S4 battery and see if it helps

Thanks MaryAnna and Obagleyfreer. I've already tried what you just suggested.
No luck
I tried to give it to Samsung, and look what I've got:
They told me to look for support in the country I bought the phone.
This is ridiculous. It's a shame.
That's when I regret changing my iPhone for a Galaxy.
After i installed stock firmware there is absolutelly no sound on my sgs4 what's funny is that there is a boot sound (one that plays with samsung logo when booting) but as soon as i get into system boom no sound at all no matter what i click with/without earphones basically nothing
this is on stock not rooted sgs4 firmware
And also when i try to increase/decrease sound via hardware key or in settings phone freezes or crashes any ideas ?

I have the same problem with my sister's note 4 snapdragon... updated to marshmallow and now if you reboot, it goes black screen and does not respond to long pressing power or anything... you have to pull out the batter for a few minutes then restart.
What gives? Did you find a solution?

have you tried wiping your cache?
Press Power, Volume Up and Home simultaneously.
Wait until the phone vibrates and then release Power and Home.
You should now see the recovery screen. ...
Press the Power button to confirm.
Select Reboot System Now and again, hit Power to confirm.
Hi, thanks, but yes, I've done cache and factory resetting several times. I'm trying custom ROMs now...

Thanks, nope, it isnt under warranty.

The phone will not boot at all now, probably due to flashing stock rom with PIT file.

Please help ASAP. I tried to install lineage os with MindGapps. After I flashed lineageos with twrp, I rebooted it and now it doesnt turn on. I tried to go to download mode, but doesnt.
The phone doesnt turn on. When I press and hold power button + volume down button for 7 seconds, samsung+knox logo appears and then 'phone bootloader unlocked' warning appears for few seconds.
An hour ago, somehow I managed to open its download mode. To test how it got opened, I restarted my device, but unfortunately, I couldnt go back to download mode. Is there any way to solve this problem? I want to go back to download mode
Hold the volume + and - buttons down at the same time and then plug in the usb cable into the phone.

I first flashed twrp-black or something and it didn't work properly so I installed twrp-official downloaded from website. But then, after installing the official one, the recovery got corrupted. I couldn't boot into downloadmode, but luckily, it was just some key combination that was wrong, so, with a right key combination. I booted into download mode and reinstalled the initial firmware.

Yes, it just looks like it is bricked but it is not yet completely bricked.
The solution was simple.
First, completely power off device (don't restart, just turn off). After that, by certain keys combination, go to download mode.
It seems it doesn't work while restarting but works if it is completely turned off.(At least in my case it had been so)

I do know how to enter in download mode, but even when I upload the TWRP again and start over the process it get into the same black screen. I was wondering if Samsung Knox is blocking this action.
