Updating TWRP via TWRP n recovery - Nexus 6P Q&A, Help & Troubleshooting

I had TWRP 3.0.1 so I downloaded the latest TWRP 3.0.2 IMG file and booted to Recovery and selected the image and then selected Recovery as to where to flash and it flashed no errors so I backed out and went to reboot and selected Recovery and it rebooted to bootloader and when I stroll volume keys to Recovery then power to select it just hangs there I have to do a power long press to get it to reboot back to Android. Any ideas why Recovery will not load now ?

A bad flash, perhaps? Have you checked the MD5 after downloading?

Possible bad download but at this point I can't reflash the recovery until I can fast boot .. I gotta order another Type C to USB to connect the phone to the computer for fast boot grrrrr...
Thx

Glad to help! Next time make sure you check MD5 before flashing (even then an occasional bad flash could still cause trouble, but hey, what's the choice here?) You can still boot to Android normally, no?
Sidenote: anyone knows if a micro B to C adaptor would work with fastboot?

Yeah I can still boot to Android fine jus when I select recovery n bootloader it hangs in bootloader. I have to hard reset to get out of bootloader mode lol....
Jus sucks BC now I gotta wait until friday to order a Type C to USB cable to use the computer to fast boot TWRP to recovery.. :/
I jus got this 6P 4 days ago coming from the HTC M9 Developer Edition I decided to go with the 6P over the M10 even though I would have gotten $100 off the M10 for not using my UhOh protection.
But I'm currently Stock w/ root until I figure out or understand this whole Vender thing when flashing Roms.. Jus being very cautious.
With HTC you jus flash the ROM you want but here some say jus flash the ROM and some say flash the Vender matching the ROM.. Lol,..

About the vendor img... Not too sure about the whole technical details behind them, but I just flash them every time Google updates them (think monthly security updates), at the very least to get rid of the 'vendor img outdated' popup. You don't need to flash a new vendor img everytime you update/switch ROMs, but only when there's a new vendor.

I usually just flash recovery with flashify. Never had an issue doing it that way. Or fastboot.

People have been facing the same issue all around. Even I did, last night after updating to N Preview. Anyhow, the only solution I know right now is to have a decrypted filesystem (disable encryption), for TWRP to boot and work properly.

Yeah disable encryption I believe I read requires booting into recovery and wiping User Data or something alone those line's.
Unless there's a option in Android settings to disable it idk yet as I jus had the phone a few day's.
But so far I happy with my decision to get the 6P over the M10 even if the 6P is 4 or 5 moths old...

Recovery won't flash

I had to do a complete wipe from the computer and flashed clockwork mod recovery. Since it was likely an old version I had the double 0 partition problem which I fixed by manually moving the files. I tried to update the recovery to twrp, but it won't flash using goomanager. It downloads and says it's flashed but it's not there.
I also seem to have a weird problem where I have to push the power button to get it to boot past the Google screen. If I don't push power it gets stuck there forever.
Any ideas?

Follow the sticky at the top that says flashing a factory ROM using fastboot/return to stock. Start from scratch, get it working, and then flash whatever you want.
Sent from my Nexus 7(2012) that has zero issues.

That's what I did, that's why I'm stuck on the old recovery.

This might be an odd question, but have you tried just updating CWM first, and THEN flashing TWRP? Sometimes the flash won't go smoothly with an older version of one recovery to a newer version of a different recovery- not sure why, but that's just been my experience. I would update CWM first then try flashing TWRP.
Also, if goo is not working for you, you could try Rom Manager to update CWM and then flash TWRP. It can flash either. (If you really want to flash via the device).
Otherwise, (me personally) I'd just use adb fastboot to flash a new recovery.
Hope that helps
Thanks I will try that.

No problem. Let us know how it works out for you.
Tried flashing with fastboot, now it won't boot into recovery, just hangs at the Google logo.
Still needs a bump from the power button to get it to boot normally.

Ahh, that sucks! How are you *attempting to* access recovery... via reboot menu, via adb, or via 3-button press? It shouldn't matter, but you could try all three methods to see if any way will give you recovery access. Then, if/when you manage to get in, you could reflash again straight from recovery. I'm going to do some digging to see if I can find a better solution. I KNOW I've read about the same issue before, I know there's a solution... I just have to find it again.
Worse comes to worse, you might have to reflash stock recovery then reflash custom recovery. Might be a corrupt recovery img, but I will check and try some things out and let you know what I find.
Edited to add:
Yes. there was a bug in the older bootloader that bypassed/refused access to recovery... so since you restored stock, you probably need to update your bootloader to at least to version 4.18 (via fastboot). THEN you should be able to access recovery. I can't add links, but I can give you a text link once I find just the IMG file instead of the full firmware. Honestly, I never do backups so I don't have the file on hand. However, I may do one backup at least so I can extract my boot img and give it to you.
OK, so I found the info I was looking for.
From Elsewhere:
Steps:
Install latest nexus 7 bootloader.
This fixes the boot loader bug and now you can enter recovery from the bootloader screen.
Update the bootloader to at least 3.18. Make sure NOT TO DELETE THE BOOTLOADER!!!!!!!!!!!!!
I cannot emphasize this enough!!!!!!!!!!! I bricked my first one this way.
Use
fastboot flash bootloader C:\>>>>>>\bootloader-grouper-3.18.IMG***

Do NOT erase bootloader before you flash the new one. And after you have flashed the new one type;
fastboot reboot bootloader

and check the bootloader version to make sure you succeeded.

***Or whatever you name the boot img file!***
https://dl.dropboxusercontent.com/u/19608328/boot.img.zip --> This is from MY Nexus 7. It's Bootloader version 4.23, and works with JB 4.2.2- it does NOT have the recovery access bug.
https://dl.dropboxusercontent.com/u/19608328/recovery.img.zip --> This is a copy of MY CWM, which I just updated to 6.0.3.6 yesterday.
I'd flash the bootloader, then flash your recovery of choice. Not being able to access recovery is a bootloader issue, not a recovery issue. The fact that you restored/reverted an older full firmware put you on an older bootloader that would not allow users to access recovery.
Try the new(er) bootloader, it should work. My device is a 16gb grouper Nexus 7 running 4.2.2. Before that, it ran 4.1.2 without any issues, so it should work to resolve the problem you're having.

Error message

I recently, yesterday, flashed a 7.1 from to my phone. Actually both that at available, and both times I am getting this error message on boot. I'm not sure what I'm doing wrong. Phone seems to run well though. Help? Thanks!

For the life of me I can't remember what it was .
I'm thinking it had something to do with Vendor but can't remember

Did you update the vendor image after flashing the ROM?

Just flash the vendor image to the corresponding build. Ex: build NBD90X needs the NBD90X vendor image and so on. Should resolve the issue.

Now I'm stuck elsewhere, I decided to do a full flash -_-. I formatted everything not thinking and now I have no rom on my device. I think I am stuck. Is there a way to transfer a rom to my device? I used TWRP to format my device.
Boot into fastboot mode, unlock the bootloader, and flash the latest factory image...

Fastboot just says to connect a USB Cable but it's connected. I have drivers installed. I don't have a rom obviously to enable USB debugging -_-.
If u have TWRP just boot to recovery then plug in the phone to computer and a window will pop up showing Internal Storage and jus copy a ROM/Gapps/Vendor to Internal Storage and then select Install and flash away.

I got it! I had to use another pc for some reason; my main pc wasn't recognizing it but my laptop did -_-. Anyway, where do I find the vendor image? Also how do I flash that, I remember a while back I found one and went to flash it and there was several radio buttons on where to flash it. I don't want to screw this up lol.
Thank you so much.

Nexus 7 2012 stuck in safe mode

When I restart Nexus 7 it always boot up to safe mode. Tablet first shows bootloader menu and when I choose to start, it boot in to safe mode. It looks like volume down button is always pressed on but it don't work - does nothing in bootloader menu, and in safe mode.
I don't use it for some days. I don't remember the tablet being flooded or hit. It just appears. First I thought that it was caused by some bug in LineageOS. I made factory reset, and when it does nothing I set u Android 5.1 again but that also didn't work.
Do you have any idea why this is happening?
You mean you are always booting into recovery when starting up the device? This may happen if there is no valid boot.img / system.img installed. How did you install the current system on your device? Do you have an unlocked bootloader? Do you have the latest bootloader (4.23) installed on your device?

Last thing I did is option Flash Stock + Unroot in Nexus Root Toolkit.
Yes I have bootloader 4.23.
Sorry, but I don't know what the toolkit is doing and whether everything went as expected .. that's the disadvantage of using toolkits.
Best would be to learn how to install and to use fastboot and after that you can decide either to flash stock factory image again or to upgrade to one of the custom ROMs available for the Nexus 7.

I think you don't understand me. Nexus Root Toolkit have nothing to do with this. It works 3 years with my Nexus 4 and 1 year with Nexus 7. This problem appeared long after installation of LineageOS.
Ok, I installed Android 5.0 manually and I still have this problem.
Did you notice any error messages while flashing the stock image? Did you do a factory reset after returning to stock?
I am still thinking that your bootloader is closed and you are not really flashing / changing the ROM, but flashing fails and you are remaining in the same state as before. Just as an idea ...
Sent from my Nexus 7 using XDA Labs
I would do one step at a time assuming fastboot and adb work. Search for adb minimal. Download stock zip to same directory. Run fastboot oem unlock. Unzip stock zip and try running flash-all.bat it flashes compatible bootloader and stock zip. If that doesn't work img files are inside stock zip and can be flashed separately.

Sorry for leaving you like that.
I took the risk and ordered flex cables with volume buttons. Now the tablet works fine. I'm sorry for the trouble.

intermittent imei/data loss after rebooting device

hi guys, just got my device on the mail, global version 64GB
1. unlocked bootloader via fastboot
2. flashed magisk and custom black boot logo via TWRP
I only temporary booted TWRP to flash those 2 zips, no permanent flash of TWRP so I can easier install future monthly OTAs by only unistalling magisk
anyway, the weird thing is after I reboot the device there is no data/no imei... then I reboot the 2nd time and everything works good
repeated several times and data/imei is off and on like that every other time
can anyone help what I should do? Im kinda freaking out, because I dont have any efs folder backup or any backup really, since I only wanted to flash magisk to have root, and get rid if the bootloader warning splash screen, keeping everything else stock
what is up with this issue I barely modded the device, just root and splash screen
I have data now, but scared to reboot device, anyone can help me [emoji19]

Double check make sure your on the latest TWRP. After flashing I use the volume keys in bootloader mode to switch to recovery. Then power button to confirm the action . Like mentioned above flash magisk 16 to make recovery stick.
