[Q] Need Help stuck in bootloop after flashing recovery - Nexus 7 (2013) Q&A

So just as the title says i decided to root my n7. Everything seemed to go smooth until my nexus 7 was stuck on the boot animation screen for about 20 minutes. I tried doing a factory reset in TWRP and it said wipe failed. I decided to flash CWM instead and do a factory reset but i couldn't. It said error mounting /data. I'm not sure what to do googling around didn't seem to work.
TWRP gave me a message saying SU is not installed after i installed the recovery so i clicked instal SU. I'm not sure if that contributed to my problem or not. Any help would be greatly appreciated.

Ok so i figured this out.
So for anyone who ever gets into an endless bootloop with the inability to wipe data you need to do the following.
1. Download the latest Factory image from google.
2. Exctract the files into your platform-tools folder an run the "flash-all" command this video illustrates it perfectly http://www.youtube.com/watch?v=bsss9e71bKo
3. And you're done! hopefully this helps someone out

[Q] Always booting to Sys Recover (3e)

So I rooted with Odin using the "SPH-D710_Zedomax_Kernel.tar" and then unrooted with Odin using the "acs-eg30-stock-kernel-pulled.tar". Once I unrooted everytime I boot my phone up I get this error message:
'gaudi_bootimage.jpg' draw failed
and I boot into System Recovery (manual mode), and if my phone is plugged into laptop or wall charger when I power down I receive the following error message
'charging.jpg' draw failed
Even when I root back, it still always boots into recovery mode and boot up error message is replaced with the Galaxy S2 GT-I9100 splash screen, but I still get the 'charging.jpg' draw failed error.
On both occasions (root or unroot) I can still select reboot system now and the phone finally boots up fine, but I'm trying to eliminate the jpg boot and charge error messages and boot directly into he phone without having to select it in recovery. I have done a complete factory wipe with the same results as described above. Any suggestions?
try reflashing the stock pulled .tar file? and a nandroid backup/stock OS?
Looks like some files may be corrupt.

I have tried reflashing the stock pulled .tar file and resetting to factory defaults, neither of these worked. Are the files 'gaudi_bootimage.jpg' and 'charging.jpg' something I can place in a specific directory that will avoid this boot up into recovery problem? I'd like to overwrite those potential corrupt files with good ones.
They are in /mnt/.lfs
I'll see if I can pull them and post for you.
Oh wow!
There's a treasure trove of stuff in this directory. I think it's hidden but using Android Webkey I got to it. I'll post some other "boot" images from here. The initial "Samsung Galaxy S II" image isn't the only one. I like the Iron Droid one, though it doesn't seem complete.
Anyway, here's the .zip of all the images in that directory.
I saw you wiped fator reset. But dis you also wipe the cache and dalvik? Then do clean install with CWM 5.x.x.x ? I would recomend that id u haven't tried thus yet

Alright a quick update (not positive):
I copied the files onto the /mnt folder, but unfortunately after I copy them they still don't appear in the directory. I reboot and I still receive the same 'gaudi_bootimage.jpg' draw failed & 'charging.jpg' draw failed. I do have root access by the way and I'm copying these to the directory using Root Explorer.
I also took the following steps:
Installed CWM 5.0.2.3
Performed a nanroid backup
formatted the system volume under 'mount and storage'
wiped data/factory reset
wiped cache partition
wiped dalvik cache
All that still with no success.
Another thing I'm noticing is when these error messages show (on boot & after power down while connected to charging source) it automatically boots into recovery. There has to be some way or place these files are being called for me to replace them to make this annoying issue go away. Any more suggestions?
So you have tried reinstalling CWM to see if it helps?
Seems (no expert here) that something is corrupted. Not sure exactly what but possibly part of the internal storage or the primary or secondary bootloader. I really hate to jump to something that extreme but i just don't see another reason it would be acting up like that.
I would download CWM one more time and check the MD5 before using ODIN to flash it. If it still does it - return to stock (remove the yellow triangle if you have it) and take it back to the store. Should be under warranty still.
Did you ever solve this problem as i have the same issue.

HELP! BootLoop trying to root boss' CDMA GNexus!

Okay, so I'm trying to root my boss' phone: I did warn him that things could go awry but we went ahead and tried anyway. I'm using adb commands from a mac. I downloaded CWM toro (for gnex) and the lastest su.zip file. I unlocked the bootloader, flashed CWM, and was able to push su.zip over to the /sdcard through the command line (it reads 3985 KB/s and how long it took, etc.) - Now still in CWM, I can't seem to access the sdcard. I'm getting a "Couldn't open diretory." which shows up twice, followed by a "no files found" error. But the terminal window shows that the file was pushed over. Rebooting goes into a loop halfway through the splashscreen. Still have access to CWM and able to enter fastboot mode through holding VOL UP and VOL DOWN while powering. Any help would be appreciated!
EDIT: Tried Wiping Cache, reboot to recovery - still no luck. Tried Wiping Dalvik Cache, reboot to recovery - still no luck.
EDIT: Tried downloading appropriate recovery images from Google's website. Flashed files in order from http://forum.xda-developers.com/showthread.php?p=20441992 <--these instructions, everything checked out okay and still looping at boot.
I hope this is reversible. Seriously, anyone? Any help is appreciated.
Didn't think it would go like this as I rooted my GNex with ease (GSM version) using the same method.
Reflash cwm
+1 for reflashing CWM
Your FIRED!

How to repair Wileyfox Swift when I can get into TWRP but not bootloader

Hi. I've just updated CM13 to the latest nightly using TWRP, but now the system just boots into TWRP - that's whether I select boot system, recovery, or bootloader. I tried restoring from a TWRP backup or another copy of the nightlies zip - it all seems to work fine but doesn't solve the problem. I can connect to the 'recovery' device using adb but adb restart bootloader just loads TWRP again. I've tried wiping first the dalvik/cache, then everything but the internal card, then finally everything but nothing seems to work.
I did get something a little bit like this a few days ago because SuperSU was complaining that I needed to update the binary. I let it do it the way that it suggested one does when TWRP is installed and afterwards couldn't reboot into system, but after a few minutes of frustration sorted things by wiping various partitions.
I attempted to load the full system restore files (cm-13.1-ZNH2KAS29G-crackling-signed-fastboot-74bb753396.zip) using TWRP but that didn't work (I imagine because they're designed to be run via fastboot). I tried loading them via the ADB sideloader option included in TWRP but it failed after a few seconds (I think the message was 'transmitting 0.0x'
I opened that zip and copied the various files to the external card, but I then baulked at installing the image files manually because the only partition option I'm given is boot and my understanding is that each image file should go into its own partition.
The only other potentially pertinent information I can think of:
TWRP keeps reporting "E: Unable to find partition size for '/recovery'"
Has anyone got any ideas please? I had been musing that my next phone would have OTG and NFC, but I wasn't planning to upgrade just yet if I don't absolutely have to.
Have you got it fixed? And if yes - how? I am stuck in a similar situation and can't find a solution for it. Tnx in advance.

[solved ]Update with Flashfire and current factory image leads to bootloop into twrp

Hi,
I wanted to update my Pixel C to the most current factory image with flashfire as i did it before a few times without problems.
So I DL'd current factory image from https://developers.google.com/android/images#ryu, opened it in flashfire and said it should flash the normal partitions except recovery as i don't want that it overwrites my TWRP.
Flashfire analyzed the zip file and after i said "flash" it restarted my Pixel into a black screen. At this point i was wondering that nothing more happened.
I waited for 10 minutes so that maybe something in the background could happen, but there was no further action. The screen kept black.
After these 10 minutes i restarted the device but now it always runs into TWRP directly instead of starting the system
I also tried to install the zip manually in TWRP but it tells me
"Could not find 'META-INF/com/google/android/update-binary' in the zip file.
Error installing the zip file '/usb-otg/ryu-n2g48c-factory-0bc0ee15.zip'"
As you can see from the error message i also tried to dl the file again and install it via OTG but the same thing.
If I go into the file manager in TWRP i can still access the folders from the sdcard.
The bootloader is unlocked of course.
Anyone an idea what i can do without loosing all the data?
Thanks in advance
Download the full system image and extract it. There should be a flash_all-file (bat for windows of sh for linux). Open it with an editor and remove the "-w" option in fastboot. "-w" is the switch for wipe. After you removed it, you can flash the complete image and your system should boot again into android. After that you can install a custom recovery, etc. again.
Thank you peter, worked like a charm for the system flash. Now follows the TWRP etc again
EDIT: ok, the system flash was the only thing that worked like a charm. I tried flashing TWRP with NRT but didn't work. I am stuck now at a "no command" screen when i start the device.
To install the custom recovery NRT tells me that i will loose all my data, so i wanted to backup everything.
Unfortunately i can't backup everything now as the temp booted TWRP demands a password to decrypt the sdcard, but i only have a pattern and no password set.
So now i try to flash everything again and to install twrp without loosing all the data.
Hey everyone I have flashed android 7.1.2 August again and android started afterwards without any problems. I was able to restore the backup of all the apps from Google.
Than I wanted to get back root and flashed TWRP with Nexus Root Toolset, but now only TWRP starts every time I switch on the tablet. Any ideas what I can do?
EDIT: I fixed it somehow with flashing the whole firmware package again and than the TWRP wich broke the startup again so i ended up in a TWRP bootloop. Therefore i flashed android again and TWRP 3.0.0.0 than TWRP 3.0.2.4 (something like that) and after like 3 to 4 different flashing steps it worked again. I have no idea what happened during the first flash of Andoir 7.1.2 but i think that something broke there.

SM-T320 is rooted, but no "advanced" in recovery mode

I apologize if this has been covered before, but several searches haven't turned it up.
I'm trying to upgrade my Galaxy Tab Pro 8.4 to Android 7.1 and I'm running into a roadblock in the recovery mode. I have options for Wipe data/factory reset and Wipe cache partition, but there's no Advanced option, so I can't wipe the Dalvik cache.
The tablet is rooted -- I checked it after running Odin, and even ran Odin once more to be sure -- and I had Debugging checked under Developer Options, so I think I should be seeing the Advanced option, but it's not there.
I tried installing the new OS anyway, but I got failure messages, and then the tablet rebooted itself to 4.4.2, still rooted. I've restarted Developer Options and re-checked Debugging.
I must be missing something, but I can't see it. Thanks in advance.
This is driving me insane. Every time I think I'm making progress I run into a roadblock. At this point I'm just trying to load/install TWRP recovery so I can do a thorough wipe, including the Dalvik cache, but although I can find the flash file in my file manager, TWRP doesn't see it.
On the tablet's own storage TWRP starts its search at emulated/0, but I can't find folders in the file manager called emulated or 0. It will also look in sdcard, but even though I've copied the file there, TWRP doesn't see it, although it seems to be looking for "extsdcard." It also doesn't see zip files I've downloaded to the sd card, if that matters. It seems that TWRP can only find folders, not files.
I uninstalled and reinstalled TWRP, but it's the same. So I uninstalled TWRP again and tried to go with CWM, but it's not compatible with my tablet.
Part of me knows there must be a solution somewhere, but this has just about reached the point of "life's too short." If anyone can offer any help, it would be greatly appreciated.
I've finally had some success! I found instructions for installing TWRP with Odin, and they worked. And so, I expect, did the TWRP backup of the tablet's OS. All I need now is a Nougat 7.1 download that works; the one I have now:
Galaxy Tab Pro 8.4 Lineage OS 14.1 [mondrianwifi] [Android 7.1.1 Nougat]
...isn't working. TWRP attempted the zips I downloaded (OS and GAPPS?) but the verification failed. So at this point I can only boot to TWRP. If I just start the tablet normally, it hangs at the Samsung logo screen, and while I can turn it off, it starts itself again after 10 seconds or so, requiring a boot to TWRP and shut down from there.
I'm hopeful I'll find downloads that work, but some of the links I've found appear to have expired. I should be able to go back to 4.4.2 from the backup, but since I've gotten this far I'd like to follow through. It looks like I have more searching ahead of me.
More success! I found the following link to the OS and downloaded the Pico GAPPS as that author suggested, and it worked! My thanks to Marc0601!
