[tutorial][updating TWRP for 4.4 compatibility]

Ive noticed many people with older TWRP versions having problems with the updater script when installing 4.4 roms you need to be on the latest version of twrp (CWM may also need to be on a recent version). This tutorial will cover TWRP. Goo manager will not work for installing the latest TWRP recovery version on grouper. The following will give you the basics on how to use fastboot to flash a recovery.img (In this case twrp)
Things you will need:
A PC
Android SDK http://developer.android.com/sdk/index.html
TWRP recovery.img for grouper http://techerrata.com/browse/twrp2/grouper
A basic understanding of terminal/command prompt
You will need a PC and the android SDK (SDK http://developer.android.com/sdk/index.html) for fastboot to push the recovery file. TWRP can be found here (http://techerrata.com/browse/twrp2/grouper) you need the 2.6.3.0 version. Extract your android sdk and move your twrp image file (openrecovery-twrp-2.6.3.0-grouper.img) to the platform-tools folder in the sdk (This is where fastboot/adb are). For simplicity's sake rename your twrp file to recovery.img Enter command prompt or terminal depending on what OS you are using (windows/linux) and navigate to to your platform-tools folder in the SDK folder (where you should have moved your recovery.img) using the cd command. (plug device in) Once there check to see if you device is connected and seen with the adb devices command hopefully you will see a wonky alpha numeric code with "device" after it. If you dont you need to enter developer setting to enable adb. You do that by going into settings/about tablet and tapping build number 7 times. That should give you a developer options in settings check to make sure USB debugging is enabled. If all is well reboot your device into the boot loader with the adb reboot bootloader command once your device is at the bootloader check fastboot with fastboot devices you should see another wonky output with "fastboot" after it. The final command to push your new twrp image will be fastboot flash recovery recovery.img You should see some output saying how long it took to push the file it should not take that long. That should cover it! Now you should be good to go with the 4.4 rom's floating around.
There are many tutorials online explaining this process I just thought customizing it to the grouper would help those less comfortable with adb/fastboot. It's always a good idea to know how to use these tools you never know when you might need to use them. Anyone with question's feel free to ask.

Or just install flashify and it basically does all of this for you. I did it and it worked.

That will work. But knowing your way around adb/fastboot can't hurt. There won't always be a GUI to do everything for you.

Didn't know of flashify, awesome. Thx, really fast and easy method. Best thing is I didn't even need my pc for it

Thanks for the tutorial but surely this belongs in q&a, help etc not android development ;p

Actually it's suited to the General section (guides and all). I appreciate you advising the fastboot method (I use it too), but it can b a pain for people who don't have their devices configured (configuring it can be a pain sometimes too). Flashify, as one member said, is a great alternative. BUT you *may* brick your device if you flash something to the wrong block device (possibility of that happening to an expert user: 0.0001%; possibility of that happening to a new user: 1%). Just my two cents.

I agree guys this should be in general. I've never posted anything but a build and didn't even think about it. Do I need to get a mod to move it? As for flashify sounds like a great tool. I've never had the pleasure of using it but if it works and people are comfortable with it more power to it. Personally fastboot is what I'm comfortable with it might seem a little in depth but really its quite simple especially if you use adb for logcats and are setup.

OP No worries, moved and thank you.

To flash 4.4 ROMs one could follow this tutorial, or one could simply flash this .zip of the latest version of CWM:
http://forum.xda-developers.com/showpost.php?p=46053223

So, i've bricked it already.
Hello experts and knowledgeable persons!
First, i'm a noob.
I decided to flash KitKat as I play a WebView based game and thought the WebView Chromium of KitKat might make it run faster as it ran pretty slow. On the Paranoid Google+ page it says you need TWP 2.6 later and other sites say 2.6.x. I had 2.6.0.0, so did a backup of boot, data, system and recovery, copied to PC and then tried installing KitKat, it failed. So I updated to TWRP 2.6.3.0 and it failed again, tried a second time and it updated.
The game didn't work well on KitKat, so I restored my original version. I then decided to take screenshot of game not working on KitKat to complain, so tried installing KitKat again forgetting to update to 2.6.3.0 as the restoration of the backup restored the prevous 2.6.0.0 recovery, was a noob and tried again and i'm now left with a Nexus 7 in a boot logo loop.
Restoring the backup fails, as does installing the KitKat Zip or Opensensation . If I try flashing TWRP 2.6.3.0 via fastboot, it says success, but when I reboot the recovery i'm still in 2.6.0.0. I can boot into 2.6.3.0 using "fastboot boot", but it still won't restore the backup or flash. I also have a backup of the OpenSensation rom (wanted to try PDroid and it was the only rom I could find prepatched) which I made on 2.6.3.0, that won't restore either.
So now what do I do, as I don't want to make things worse. I am doing a factory reset before installing. The error i'm getting is "symlink: some failed"", "can't open destination log file: '/cache/recovery/log'" and "E:Unable to open '/cache/recovery/log'"

I'm sure this is not what you want to hear but if all else fails push the factory.IMG you will be starting from square one. You can try pulling your backups off but might as well start over for 4.4

Thank you very much for this recommendation. Really nice. Simple and took out all the nervousness of using the computer to push these files etc.
REally truly best for flashaholics.

question
Won't it work too if you just flash the zip from twrp itself? I'm running 2.6.3.2 and I read somewhere that i can simply install the new version (2.7.0.0.) zip from the recovery itself..Is it right??

Hey!
Thanks a lot. Really helped solve my problem!

No problem

This doesn't belong in Development.

Actually i am not sure where should this be.. I'd request modders to please move it to the correct board!

Thanks man!

Since you've probably lost your custom recovery upgrading to 5.0.1, you can grab the TWRP images for Nexus 5 here: http://techerrata.com/browse/twrp2/hammerhead
I believe you need to use 2.8.1.0 since 2.8.2.0 either doesn't work or is causing problems for many users.

Isn't CF-Auto root adding files from the 5.0 release over the 5.0.1 ? Isn't it safer to wait for a 5.0.1 autoroot?

How did you update from a rooted (with CF-Auto Root) 5.0 to 5.0.1 you just received the OTA and installed it without any problems ?
I like to know because i am on 5.0 stock just rooted with CF_Auto root.

So no more need for CF-Auto?
Just flashing SuperSU zip with TWRP is enough?

I flashed a Custom Rom Using TWRP which doesn't have any root permission...

Guys, i installed the 5.0.1 update by fastboot flashing system, boot and radio. I lost my custom recovery tho (CWR). I now tried to install TWRP, but after flashing the recovery image, the recovery still hasnt changed. Could i just flash CRW or should i use TWRP for this version?

This. I flash with it here since 4.4.4 and it did everything just fine. Not only it is an app to automatically root, but it gives very good hints, and provides lots of others features like installing Apks, getting a adb prompt, and so much more. Greatest third party Android app I have tried. Highly recommended, didn't even had to wait they update it for 5.0.1, as soon I got the 5.0.1 OTA notification, Nexus Root Toolkit was already ready for it.

This is lollipop security, custom recover wouldn't stick, after each reboot it will replaced with stock one, of course there is a way to make it sticky just search the forum.

That's always been enough. You can use Cf's auto root if you don't want to use a custom recovery.

[Q] Updete Nexus 6 to newer build

I have Verizon Nexus 6 which came with LMY47E system but as it is well known LMY47I is now officially available. but with older radio. I'm already unlocked and rooted and have latest version of TWRP recovery installed instead of stock recovery. So my question is can I extract system.img and flash using TWRP install option and get newer system but keeping original radio and user data without data wipe? Should I wipe any cashe before flashing to avoid possible problems?
Anything else I should flash to make sure I will be able to use phone without problems while keeping root and unlocked bootloader or i will have to do unlocking and rooting again? Any help is appreciated

Fastboot flash system and boot and you'll be good.

Thanks for quick reply. So I can't use TWRP recovery? Flashing boot will not wipe root and bootloader?

It's a lot easier to just flash system and boot in fastboot. Flashing system will erase root but after you flash system and boot go directly into recovery and flash Su.

That's exactly how I understand and that's why I"m asking if it's possible to do the upgrade using TWRP recovery by flashing just one IMG file at a time in specific sequence and than restarting the phone while still keeping current radio and data plus SuperSU at the end

You can't flash the IMG files in twrp. You'll need to use fastboot. Just flashed whichever files you need. I usually flash everything but recovery and then just reroot. Takes about 10 minutes.

Was trying to flash M and now I have no OS at all.....

So a while ago I rooted my phone after doing a lot of research (because I have no idea about this topic) and it was all good (it was only to use some apps, no ROM or anything)..
Today I wanted to install Android M, I also searched a lot and ended up using the same thread ([HOW-TO] The Nexus 6 All-In-One Beginner's Guide) and used step 5A and 5B.
When I reached the point of choosing the .zip file to install (on TWRP) it said: "This operation may install incompatible software and render your device unusable", and when I tried to flash it said "Failed" in red.
Now when I try to reboot to system it says "No OS installed" and if I try I only see the white Google logo with the open lock at the bottom of the screen.
I can only use the recovery mode and Bootloader mode.
Any help is really appreciated...

Try to use the software from Android developers
try to use the factory image from Google developers just search for android factory image
in case all steps fail try to psuh the files using fastboot flash (partition) (partintion).img

I can only use the recovery mode and Bootloader mode...

That´s what I was going to ask about just now.
I tried flashing a ROM and it worked fine, tried flashing M stock image but it did not work.
So what should I do/use to flash the stock images from Google?

You use fastboot from a computer to flash stock images. Custom recoveries are used for flashing custom rom zips.

These are twrp flashable zips http://forum.xda-developers.com/nexus-6/development/fxz-nexus-6-recovery-flashable-fastboot-t3066052 otherwise you will need to have adb/fastboot working on your computer and use fastboot to flash images

True, but if you're setting things up properly for the first time then you're installing both fastboot and adb.

I flash the boot.img and there's no problem at the boot time, then I flash the recovery, and the same, when i reboot it works like a charm.
But everything goes wrong when i flash with twrp the supersu beta v2.52 or v2.56, when i reboot, it doesn't boot...
My phone continue on the first bootanimation (before flash this file it boot then says android, request my pincode and start booting, but no this time, just still doing the [email protected] bootanimation. I am kind of desperate, can somebody help me plz?
DONE, I re-flash system and do it again, thanks for everyone

dont use supersu 2.52, use supersu 2.51 instead http://www.apkmirror.com/apk/chainfire/supersu/supersu-2-51-android-apk-download/

yes. but you will need that boot.img or any other custom marshmallow kernel as well for root. btw, a boot.img is a kernel. also, you can flash boot.imgs with twrp now too, you just have to select the ability to flash it in twrp.
