Trying to Unbrick Nexus 7, stuck in Recovery Mode - General Questions and Answers

Hi there,
I just bought the newest version of the Nexus 7 the other day, and decided I'd like to root it since I never bothered to with my old one. Big mistake. I followed what seemed like really simple instructions online, but after doing everything it said, my tablet is stuck in reboot mode. At first, it would show the Google symbol when I turned it on, with the little unlocked padlock at the bottom. Then it would show the circular colour symbol that would just keep moving -- no matter how long I left my tablet on it would just stay in this mode. Most things I've researched online so far just say "easy fix, go into fastboot mode and it will go back to normal". My problem is that sometimes it doesn't even let me see that screen, so I have to hold the power and volume button down several times in a row to see anything. Sometimes it will go straight to the Google symbol. When it finally did work, I pressed 'Recovery Mode' and the Google symbol appeared, this time without the padlock underneath it. Now it has switched from the circular colour symbol to the X colour symbol, but it still won't go past this. Also when I first reboot it, it shows the dead Android after the Google symbol, then a minute or so later the coloured X will appear.
Anyone know how to help? I've also read about restoring to factory settings and downloading all of these mirror images, but frankly I haven't found a solid 'how-to' yet. I am a Mac user so please only reply with someone I can fix with compatible software.
If anyone could help me this I would really appreciate it. I am stubborn and this will drive me nuts until I find a solution.

[Q] Galaxy Nexus Boot Loop (stock)

I have an unlocked HSPA+ Galaxy Nexus imported from the UK to the US. Ordered from Negri Electronics.
It's not rooted or modded in any way.. Mainly because I don't know how to. As far as I know, it's running stock ICS.
I was using it normally, (using the fb messenger app if it makes any difference) when it suddenly rebooted by itself. The Google logo comes up, then the start up animation, and sometimes the home screen will appear but is not touch sensitive (i cannot slide it to unlock), and then it 'hangs' and the screen goes black. Repeat.
I've tried to fix this by myself and there's a video on youtube (sorry, noob here. can't post links. video is by robbidwv and title is "my galaxy nexus won't boot..") of the same problem that I have, but the posted solution doesn't work for me.
So far, I have entered Coin Mode and pressed Start. Entered Fastboot mode and gone into Recovery Mode (no options appear after that. it just starts booting up and the loop begins), and I've also tried Restart Bootloader.
I've almost given up. Now all I want is to extract my SMS, if they're still on my phone. I can't access the folders on my computer because it won't boot up and connect. Is there a way that I can extract my SMS by using DOS in either Coin Mode or Fastboot mode?
Or even better, does anyone have a solution to this boot loop problem? I'll contact Negri Electronics tomorrow and hopefully they can send me a replacement.
Please help!! Thanks
that problem just started happening with me an hour ago!!
i hate this!!
we need a solution please!
Hey guys, sorry about the issue.the major problem I see here is you wanting to retrieve your txt messages, which might be possible with a little Modding, but if yourwilling to lose them to get a working phone back, then this is what your going to have to do. Make sure your phone is completely off. Hold the 2 volume buttons and the power button together. You will get into a mode with an android Guy. Press the volume button up or down until it says reboot recovery at the top. Press the power button. It will rebootand come to a screen with an android. Hold volume up,down and power at the same time. A menu will come up. Go down to wipe data. Click it, and after it is done reboot. Your phone should work now.
If this helped you, or you simply appreciate me taking the time to write this out then please press the thanks button
Hey!
Thanks. Yeah I 'fixed' it already. I was just about to post something similar. After a while I just gave up on trying to recover my data. Good thing that Google syncs everything so the only issue would be recovering my messages, which I decided weren't worth sending it in for a repair which would probably not be able to recover anything anyway.
The thing I didn't know about was to press power + volume up WHILE on the recovery screen. I thought navigating to the recovery screen was it!
Still, this kind of sucks. I love my GNex, but I can't help but be slightly pissed seeing that my crappy iPhone 3GS never did this in the 2 years I had it. Oh well, hope it doesn't happen again!
hey guys! i also did a complete wipe on my phone and got it working again!
but i wonder why this happened in the first place?
last application i installed before the crash was double twist, i dunno why but i feel that it was the reason behind the boot loop!
Sorry for reviving this thread, but I just had this happen to me TWICE!
It happened to me first last Monday, the 23rd - the phone crashed when trying to send an email with an attachment - and went into a boot loop - Google logo would appear, no make it to the animation, and reboot....
I performed a full reset and things worked again. I didn't install all the apps I had before - figuring it must have been due to some app messing with the OS.
Well, it happened again to me yesterday! I was connecting to my bluetooth headset when the phone crashed and went into the boot loop. Full reset worked again, and I've installed even fewer apps - essentially only those that I use on a daily basis.
My phone is still on 4.0.1 and I'm hoping once 4.0.4 is pushed this may get resolved? I have a canadian GNex from Negri. I will call them again (I called the first time, but when the full reset worked I never contacted them again).
I would like to this this is a software issues, and not hardware.
I have the same problem. If you figure it out let me know.
Today my phone also entered a boot loop: [Google logo]->[black screen]->[vibration]->[Repeat]
I tried Recovery Mode, but this is what happens: (sorry for the link but I am not trusted with powerful tools such as outside links apparently, as I have not yet reached the maturity of a person with eight posts... )
dl(dot)dropbox(dot)com/u/53568097/Android.jpg
This is what I see when I navigate to Recovery Mode
For a split second I can see an image of an Android with spinning cogs in his innards, but then this little sad fellow appears. WTF is this?
EDIT:
Oh, and I'm running Android stock 4.0.2, never rooted or unlocked, Swedish. At the time when the phone started doing this, I was using Endomondo, and was about to set off on my bike when it died on me.
Stock ROM galaxy nexus bootlooping after wiping data also.
Hi,
My GNex went into a bootloop so i searched xda and found that factory reseting would be helping my prob. But after wiping the data also its still in going through the loop . Please help .:crying:

[Completed] [Q] A Tough Bootloop Problem...

Good day to all. I'm here resorted to ask about my problem here because I really can't handle it. I been googling for days. I'm ran out of resources from both google and tablet. So, I hope you can help me here. Note I'm going to write this in FULL detail here, so expect this to be a extremely long post. (I been warning you) So here goes....
Anyone uses the brand Ramos?(kind of unpopular brand) I use Ramos W21, it's been using it around 1 year and a half, and it endured a lot of problems, but fixed by researching on online forums and apply various methods there. Now, I think it's finally gave up...
One time, when I opened it and play my usual apps and browsing, it caused the errors " unfortunately
google.process.gapps has stopped", unfortunately browser has stoped",and "unforturnately google play has stopped". Then, I tried to clear data the similar apps in settings as usual, and even disabling them. Then more errors exploded, and "unfortunately launcher has stopped" appears. The menu screen(where the usual wallpaper and shortcut apps are located) turns black, while my running apps are still there running. When I pressed the back key to exit the app, now only tons of errors from the launcher appears endlessly(while the screen is black.
The time I finally turned it off by hard reset it made its way to the main problem: the bootloop.
Okay, here's where the thing gets real. It opens with the usual ramos logo, but the next one is a silver flashing android logo instead of enlarged ramos logo with spinning fire from the letter o(which is NOT my usual boot up screen) When I turned it off, it reopens again up to flashing silver android logo and the cycle repeats, even with pin reset until battery dies out. No recovery mode, so I can't use it to fix this. USB connections can't be recognized when inserted to PC. And no, the tablet is not rooted, and I don't customized anything, no mods, and no fancy roms. Just using a stock rom.
So now what? All I have here is just a sd card slot, which I think there's hope in there. Right now it has two options, deal with it and fix with all of might, or repair it in the nearest repair shop(something that is pretty risky, a lot of fakes and robbers here)
Well, this is the first time I post here, so sorry for anything that goes wrong. Thanks in advance.
Hi, thank you for using XDA Assist. It sounds like a rouge app has replaced your boot animation. Rather than try to chase that down and try to fix it I'd flash the stock firmware and start all over. Unfortunately there is very little about your device on XDA. So you'll probably have to google that.
Solved!!!
Update: I FINALLY FIXED IT!!! IT WAS A MIRACLE!!! O.O
After I keep on wrecking it's power buttons and volume buttons, I discovered something decisive!
This tablet actually HAS RECOVERY MODE! Again, it has a recovery mode! However, the way how to input it is very unique compared to most devices, including other devices from the same brand!
Now having the power of recovery state, I first selected "wipe data cache". The old large Ramos logo with spinning fire appeared again! But it's still bootlooping. So I went back on recovery state, selected "factory reset" and boom, IT BOOTS LIKE BRAND NEW!!! (sacrificing my old data though)
Okay, I don't want this recovery mode powers to be kept only by me. So I'm going to share it to all Ramos users,especially the model W21, like right now!
1. To do this, you need power button and volume up button.
2. While bootlooping, hold the power button and volume button at the same time and it will turn it off(Then expect it to turn on back up again automatically)
3. When it opens up again to the small Ramos logo(no fire animation), now RELEASE the POWER BUTTON ONLY, and keep holding the volume up button. Note, this is important! If you do anymore than this, it will either black out, go bootlooping once again, or ultimately, nothing.
4. Keep holding the volume up button, then the ramos logo will disappear, and now it will enter to our holy grail, RECOVERY MODE! Congratz!
Now when you finally have a normal working Ramos tablet again, you may go there again by turning it off by "Power Off" (assuming that your tablet is open) then holding the power and volume up(then follow above!)
I hope this will help a ton for Ramos users! :laugh:
I'm glad you got it working. You should post your solution here, http://forum.xda-developers.com/general/general More people with your device will look there than in the Assist forum. Name the post something like [SOLVED] RAMOS Bootloop Problem

HELP!!! MI4c Dead after Enter Download Mode (on MIUI Upgrade)

My MI4c is stuck in the Enter Download Mode and now its Blacked out (wont turn on, tried pushing buttons and its combinations but nothing seems to work)
So, the chronology before this catastrophe happened is as follows :
>I was interested to try the new MIUI, and followed the following tutorial : miuitutorial.com/2016/09/sudah-jamannya-miui-8-xiaomi-mi4c-kamu.html
>As the story goes, i finally ended up in the Enter Download Mode (the tutorial stated that under the mode, the Screen will go Blank, and it did, up to the moment i posted this)
>The next step in the tutorial is to open MiFlash and push the Refresh button, but when i did the program responded with 'Specified Cast is not Valid'
>I tried the following solution i found in here : miuitutorial.com/2016/08/bermasalah-dengan-driver-signature-mi.html
>I did it through again up to the restart laptop phase
>The Screen was still Blank (no signs of life whatsoever, the charging lights wont even beep upon charging)
>I was beginning to suspect something was wrong, and as i checked MiPCsuite, the Tray Icon showed that no device was connected (the phone was officially dead)
>Thus i panic and tried almost everything, pressed buttons and combinations, plugging chargers on and off, etc. but nothing seems to work
There goes my story, for the record, the phone i have is still new and everything.
I havent tried googling deep for this matter, but as i am panicking i think my judgement and analyzing skills are currently on the low, so if anybody have anything that might help or links or anything please Hook me Up, I'm all Ears.
Thanks a lot beforehand and Big Ups to the XDA community.

Help with stock Google Pixel stuck in a boot loop

First off, my google pixel is 100% stock. Last night when I went to bed, I had no issues with my phone. I woke up in the middle of the night because the screen was on and very bright. It was the white google boot screen, but with a bunch of corrupted text sporadically over it, and it was stuck there. I held down the power button to reboot, but when it did it would get to my unlock screen, but be frozen there. After about 5 seconds on that screen, it would reboot itself, and just continue that over and over. I tried holding down the volume down button to get into the bootloader, but when I go into recover mode, it just gives me the logo of the green android guy with a red triangle exclamation point on it and it says "no command" below it. So I reboot, and the only way to stop the boot cycle is to to back into the boot loader and select shutdown, so that way it will stay off.
Any words of wisdom? I was really not looking to get a new phone at this point...
I'll add that I used the instructions here to try to apply a rescue OTA using ADB according to these instructions: https://drive.google.com/file/d/0Bz6x7k-VkpUJMlZ1aEliVnhMOHM/view. It completed successfully, but didn't make any improvement on the situation.
Update #2: I ended up trying to do a factory reset from recovery mode and that also doesn't seem to have helped.
Did you try installing a more recent OTA than what you originally had?
I already had the most recent OTA so I can't get a more recent one.
Try again in a few days when the February update is released. If it still doesn't work, it's possible a memory chip got fried.
If you're in the US, look up your nearest uBreakiFix location. They handle all Pixel warranties in the US. There are a number of reports in various threads of people getting their phone repaired for free, even outside of warranty.
I am in the US, but the nearest location for me is about 1.5 hours away. I guess I could give them a call to find out if it's worth the drive.
Why do you think a new OTA update would help where an old one wouldn't?
Is there any way I can flash the full image without having previously unlocked the bootloader?
Well i am experiencing the same problem on temporary basis since 2-3 days and the problem seems to be with the power button. I get it fix when i take it out of the body cover and try to clear the dust around power button and seems to fix it but it still happens in the morning or at night at home.

Black screen except for camera? J7 Crown. no USB debugging. Recovery mode access

Situation: Samsung Galaxy J7 Crown. Never messed with. USB Debugging not enabled No special permissions (no ADB). I am able to access the Android Recovery screen. Obviously wipe cache partition didn't help, nor Lacking storage booting. Other than the Recovery and download screen: I get the Power/Restart icons when booted normally. Reset works, but power doesn't turn the phone off. No phone calls, Yes notifications. Camera from lock screen comes on (triple click on home button) and touch screen works.
I've tried to trace out the lock pattern in the hopes its still working outside this specific situation. No indication that it is.
All i want is a few sentimental pictures. Although after an entire day of frustration, finding out that the only thing that works is the camera is kinda funny and ironic.
Ive looked on XDA forums, but I'm having no luck w/ exact situation, although I'm sure someone has been in the same situation or similar enough.
Spent all day looking at options (Odin?) and nothing looks like it would work out for me.
Knowing the camera works, makes me hopeful that a mirror would work? No reaction to lock screen pattern makes me think not.
Additional (maybe irrelevant) info. Shows up on home WiFi while Find My Mobile said it was offline (makes sense with Notifications/no calls)
Any advice? Just point me in the right direction if there is one.
If not i hope you appreciate the Irony here. Thanks
(I used to be not so bad tech support, but haven't been keeping up as of late, and today was a painful reminder. Take pity on me.)
Black Screen Except Camera - Galaxy J7 Crown
Hey there anick22! I was so glad to see a search result with something referencing the camera working, on an otherwise completely black screen! I was super bummed to see that noone had replied to your plea for help with this insane problem!! I hope you found a solution by now!!
My 2 month old Galaxy J7 Crown suddenly went black on me one day, and it didn't happen as a result of a drop, or spill, or any other damage. I don't recall having put any new or different apps on it, recently, either.
The triple click of the Home button does open the camera, and the screen lights right up, perfectly. It takes it's usual beautiful pics, and I'm able to use all of the camera functions. I'm even able to view any photos I took during that particular session, buy not any prior pics, because I'm unable to unlock the phone.
"Hey Google!!" also reacts, and will display the result of any question that I may ask it, but I'm unable to go into the answers, without the ability to unlock my phone.
I have been able to get the phone into safe mode, while attempting to power it off, by pressing the power button, and then tapping on "power off" (although this hasn't worked every time I've tried). While in safe mode, "safe mode" is displayed in the bottom left hand corner, but nothing else appears on the screen.
Upon powering up the phone, all of the normal things happen. It shows "Samsung" and goes on to the blue screen to show the "Trac Fone" logo, but once the phone is booted up, the screen is black!!
PLEASE tell me that you were able to find a solution to this!!! I went and purchased a new Moto G7, (since I had a Droid Turbo 2 in the past, and it was amazing!!), and I'm beyond ready to get back to my J7 Crown!! PLEASE HELP!!
Thanks so much!!!
By the way, I'm a newbie here, as If you couldn't tell!!
