[Q] Help, boot issue

Hi everyone,
So I have never ran across this issue before. I haven't had any problems with my device and yesterday I wanted to test out the new Jelly Bam update rom from their site. The rom would not boot pasted the "Google" spash screen so I rebooted in to recovery and did a full wipe and restored via backup to my previous rom just like normal. Well then I noticed that normally when I connect my phone to my computer I see my internal memory drive pop up which I am able to click on and then access my files, but this time when I accessed it I have a hand full or folders like 0, twrp, android, etc and I had to double click on o folder to access my memory with all my files. I thought that was weird so I went on about my day. Later I tried to do a fresh install of my current rom PACman but even after doing a fresh install the phone will not boot passed the Google spash screen, and now twrp doesn't even see my backup file because its being directed to this new partition with all the folders I was talking about. I even tried using the file manager in twrp to move the backup to that twrp folder but twrp doesn't even see it.
So as of right now I can get in to twrp but I can not boot my device pasted the google splash screen. I also can't access my memory through my pc since nexus does not allow it with twrp. What do I do? My thoughts are that something got screwed up with the partitions when I flashed the Jelly Bam rom so I will need to go back to stock, does that sound about right? I was thinking of following these instructions to go back to stock and then move on from there, any thoughts or alternatives? http://www.androidrootz.com/2012/12/how-to-unroot-nexus-4-to-stock-42-jelly.html
Thank you

Trying this method to return to stock: http://www.wugfresh.com/nrt/
If no one has any input I will assume I am following the right path.

I flashed factory images a couple weeks ago and in order for TWRP to see the nandroids I copied back to my phone I put them in the following path: /sdcard/TWRP/BACKUPS/stringofrandomnumbersandletters/
Are your TWRP backups in a similar location?
If you've decided to go back to stock, I'd suggest using the following guide by efrant... http://forum.xda-developers.com/showthread.php?p=34552123

It is twrp fault. That recovery is crap to be honest.

It looks like twrp is now looking at my twrp folder in my sd card 1 not sd card 0 where I have had my backups and all my files. After trying again, I moved the TWRP backup to the sd card 1 twrp folder, twrp recognized it and I restored from backup....but when I reboot I am still stuck on the Google screen. Not sure what to do.

Since I can't move anything to my memory, any suggestions?

If you've got adb and the proper drivers installed on your PC you could try:
Code:
adb push ROM.zip /sdcard/ROM.zip
from the command prompt. Obviously use the name of the actual ROM.
Edit: ignore that, just read the post where you managed to restore! D'oh!
Have you tried clearing both caches?

The only issue is that my phone is not recognized as having debugging on when I use the Nexus Root Toolkit. Would it matter trying to push via adb? Also with your code, can you specify exactly what I should type. Mine shows C: \Users

If I were you I would not rely on a toolkit at this point. If you boot into recovery you can use adb commands to push the files from your computer to your phone.
Edit... Spec-Chum's suggestion of wiping caches is a good one. Have you tried that while booted into TWRP?
You could also try the following from within TWRP:
1. Factory reset
2. Wipe system
3. Restore nandroid backup
4. Wipe caches
5. Reboot

And that's were I am stuck right now. I am not a pro at using adb commands, never used it till I got my nexus 4. Right now when I launch the cmd it shows "C:\Users\My User Name\Desktop>", not sure where to go next. I guess I am not sure what I should be pushing at this point either.

Oops...it seems I was editing my post at the same time you were responding to it...take a look at my previous response again
I'm fairly new around here but I can help with the adb commands if you need. Hang in there

Yeah. I tried wiping cache/dalvik/system/factory reset and then both restoring from backup or flashing the latest PACman rom which is in my sd card. Right now I am reading the http://forum.xda-developers.com/showthread.php?t=2018179 guide to see if I can use adb to flash my rom or another recovery. Makes sense if its the recovery not letting me flash anything, but i'm not a dev. At least I am able to get in to recovery to begin with, good sign I guess.

If you can boot into bootloader and recovery there are many options to help get you up and running again. That guide by Jubakuba is really good but if wiping and restoring your backup from within TWRP didn't work I would highly suggest reading efrant's guide on returning to stock...I posted the link in an earlier reply.

I was able to flash cwm using adb, now trying to do a fresh install

Nope, doing a fresh install didn't work. Now its time to restore to stock. ......

One problem:
"
5) Extract the files from within the .tgz file which you downloaded in step 3 using 7-zip, not WinZip or WinRAR or whatever.
6) Make sure you have extracted ALL the files (including extracting any files in any archives inside the .tgz file). You should have six (6) files ending with .img in the directory you created in step 1. The other files you extracted from the .tgz are not necessary;"

Its weird adb will not work on the computer unless the files are in the platform-tools folder in androi sdk. trial and error, just finished flashing system....

should I do this command, I really don't want to lose my stuff:
10) Optional (NOT optional for n00bs) -- Flash the data partition: fastboot flash userdata userdata.img Note: this command will wipe your device (including /sdcard), EVEN if your bootloader is already unlocked. See note 2 below.
Well, I didn't and finished the process...did a reboot when I was done...now its on the Google screen...just waiting....I'm seeing a Nexus X splash screen!!!...
Update: Its taking a very long time, hopefully it works...going to give it another 10 mins

And we have BOOT... thank you everyone! Now I have to root this sucker!

For Those Who Semi-Bricked Their Nexus 7 0MB Interal Storage

Hopefully this helps people in my situation.
So on the first day of having my nexus 7 i found a way to have no OS and 0MB internal storage showing in TWRP. Yah i suck.
I tried tons of things but knew a system image was needed.
HOW: I was about to flash the superuser root for 4.3 newly released and forgot to put it on nexus so i then proceeded to exit TWRP, however upon exiting TWRP the recovery detected i havent installed supersu and asked do i want to install superuser? I though why the hell not!
I confirmed to install superuser and then tried to reboot but for 20 minutes device could not boot. TWRP showed 0MB internal storage and pushing adb files in this state yielded nothing as there was no directory
This is how i managed to have a working tablet again
1. FORMAT DATA in TWRP - after doing this your internal storage should be back and not show 0MB
2. reboot to the bootloader
3. On your computer download this file kindly given to us by phuduong and uploaded by Nburnes
https://mega.co.nz/#!PBIiEbBJ!bKpdHxegOVlde12nsu_ulEyRq7UsANLLQab1IZjLIGc
Credit to Nburnes http://forum.xda-developers.com/member.php?u=2918596[/QUOTE]
4. Once downloaded move that system.img file to your adb directory
5. With you nexus 7 in the bootloader, adb open, and file downloaded copy and paste this command into adb terminal
fastboot flash system system.img
6. Now you have an OS but it still would loop and wouldnt start
7. Boot into recovery and Format Data again, because for me 0MB interal storage was back again
8. Then Factory Reset
FINALLY YOUR DEVICE SHOULD BE BACK TO ITS ORIGINAL STATE!!!!!

Is that the factory image? Have you tried going from unlocked bootloader & rooted back to factory using that image?

Google has yet to release the official factory image for the new N7. However, a kind user was gracious enough to make their own. It is likely to be almost identical to what Google will eventually release and should work the same way.

Thank you! Thank you!

good stuff OP. glad you got it working again

You all are life savers! 1000X Thanks!

I tried running through this, but it didn't work for me. I think my situation is different though because I tried to install a factory image for the 2012 nexus, and during part of that process I ran the "flash-all" script which starts by deleting boot, cache, recovery, userdata, and system.
I think deleting boot screwed me up, because even though I can go into recovery now after reinstalling twrp and I can restore my system using system.img, I still can't boot (get stuck on the google logo). Any way to fix that?

So you first tried to restore from the OLD Nexus 7 Image?????

Yes, I tried to restore from the old image. Obviously fastboot wont let you install the old image, but I didn't realize that until boot, system, cache, etc. were deleted

THANK YOU!!!
This worked perfectly! I had a wiped system folder (no ROM), and obviously no USB debugging enabled. And with the lack of a factory image, I've been counting seconds to seeing somebody post this!
Just follow the instructions carefully. Thank you guys!

OP and nburnes saved my butt!

I did this and now it seems my device is booting and it shows up as N7 when I attach it to my PC. But the display shows nothing at all. It just goes blank after the Google screen. Any ideas?
After flashing everything I could think of and banging my head and the device against the wall for two hours, I finally got it to work. Not sure how exactly but the last thing I did was reflashing bootloader. So if anyone has the same problem, try that.

Thank you.

Give step 6 a little time be patient.

[Q] Need some help please

I have a Nexus 7 wifi, It is stuck at the Google screen boot looping. It is unlocked and has TWRP 2.5 which I can access. I have tried every tool kit to no avail. Need some help please!

dont use a toolkit
get to a command line and figure out whats wrong by trying to flash a factory image, or run factory reset in recovery and see if it fixes it.

I tried factory reset but it fails. I tried to flash a factory image through side load but it fails.
If I go to advanced wipe and do them one at a time they all work except data.
It appears to have nothing on intrenal or external storage.
One other thing is when I try to mount the system in twrp it asks for a password?
I have never setup a password so I don't understand this.
Thanks

Did you encrypt your device?

No, not at all that's what's so strange.

Factory reset would wipe data partition leaving nothing in data. Makes sense that it wouldnt let you wipe that when there is nothing there.
Try flashing a factory image from fast boot. Not from recovery.
Sent from my Galaxy Nexus

Would it not have to be loaded on the device? I tried it with a tool kit and it gets to the end and fails on verification.
I don't remember what version it was so that doesn't help. I think it was 4.1.2
But not positive.

Okay seems to be a problem with twrp 2.5 as far as the password I'm downloading 2.6 now.

Use fastboot to flash new recovery and system partition. You run fastboot commands from your computer not from recovery and your device needs to be in bootloader not recovery. It does not require you to load it onto the device prior

Partition internal memory to retain data after new rom?

Hi
Is it possible to partition the 64gb memory such that my data is retained after every new rom installation?
I came from note 2 and was very confident when formatting the mobile as i can take the sd card out before doing any experiments, but on Nexus 6P i have lost data 3 times as the rom. Was encrypted and custom recovery doesn't enter without formatting user data.
If partitioning is possible please help me.

You do know if you remove the security pin/finger print that twrp will be able to backup and restore data?
If I'm not mistaken they've also released a new twrp that allows decryption.
Keep in mind that ROMs of different bases may not boot without wiping. Quite honestly since Google's restore function has gotten better I haven't had the need to keep data. Everything from my home screen layout to my app data gets restored after a flash.

How are you producing this issue? What is your setup? This sounds like you're either using an older version of TWRP or N developer preview. For N Developer Previews, you must be and stay decrypted to use TWRP. Format userdata then install a modified boot.img to remain decrypted. The stock boot forces encryption.

Ok. To flash a Marshmallow rom, I believe you need to just flash the matching OS' vendor.img before booting into the Marshmallow rom. Make sure to do your factory reset and system wipe like usual.
If you intend to use N previews each month, you'll likely have to stay decrypted. I do not see a reason for the TWRP team to officially support Android N until it's official release.

Oh, I wasn't implying that. Hope you don't take it that way. I just meant, if you plan on using N previews, unfortunately this scenario is not likely to change. Just wanted to help you resolve your issue with encryption, TWRP, and switching between Android MM/N.
I don't know about partitioning but maybe it is possible? Maybe someone else can chime with their experience?

6p Bootloop of death softbrick

I was flying yesterday, and noticed that the phone went into a bootloop when I took it out of my pocket during the flight.
My phone is on purenexus with TWRP installed already. When I got back home I tried clean flash the latest Feb ROM update, wiping all partition besides storage partition before the flash. Also flashed the latest vendor image. I did not see any error during the flash process.
No matter what I try, the phone would not get past the google screen and reboots just before it gets to the boot screen.
I am now backing up data on my phone via TWRP. It's going to be a PITA if I need to RMA the phone as it was bought in the US but I am now using it overseas.
Any magical fix to this issue?

Prior to the phone had issue, it was running Nougat Purenexus rom Jan 2017 version.

I got it yesterday. Try to flash the factory image in this post https://forum.xda-developers.com/showpost.php?p=62924118&postcount=2 (Step 10)

So you have TWRP access still, and you have used the flash-all.bat method through the boot loader and it's still boned??
