[U-Boot/SD] External Recoveries (TWRP 2.8/3.0 & CWM) for Nook HD/HD+

These SD card images are built in same vein as @verygreen's here, except with a few differences:
Modified, and re-built the second bootloader (uImage) to present a menu of three recovery distributions: TWRP 3.0.0-0, 2.8.7.5, and original CWM.
Replaced the CM11 kernel therein (3.0.31) with my latest from Marshmallow. While this wasn't strictly necessary, the XZ compression helps the kernel image load faster (especially on slow SD cards).
Packaged the new TWRP RAM disks in a way that U-Boot can load them. The original ramdisk.cwm is left as was for whoever needs it.
The use is pretty standard: hold the Nook/Home button for the menu, otherwise it should boot directly into the new TWRP 3.0.0-0. People still on CM12 will need the customized 2.8.7.5 because of reasons discussed on that thread (e.g., LZMA, blockimage format). The files that were replaced completely are moved in the OLD folder, just in case. Assuming everything works well, these cards should be the only things needed to root/rescue/etc a Nook HD/HD+. Bug reports are enabled, in case major issues remain.
That being said, the images live in the experimental folder here, although they will probably be moved into the respective device folders soon.

Did fix messages make it through?+ new recovery trial
Sorry--I TRIED to send you a message by commenting on a couple of commits, and to attach an ovation uImage. Learning to program on Ubuntu, with repo, git, useing github, etc. all in a couple of months has me rather confused. I hope you got the message
Anyway, I just tried compiling a standard cm recovery to see if it would deal better with f2fs--I don't think it does, but other than coming up upside-down on hummingbird, it does at least come up from the sd card. I'll check into it further...
I note that when I tried to install a zip (internal twrp 3.0.0-0) from TWRP 3.0..0-0 on SD Card, I did get error messages about data, but somehow didn't manage to catch them in a log. ( I will try again, if you need me to). I think the install succeeded anyway. Does something need to be changed in the recovery.fstab for running from the SD Card?

Additional testing info
I've attached a recovery log from running sd card twrp 3.0.0-0 and installing a zip.. (which as, I've said I think succeeded) . Trying to do anything with data or cache will generate error messages in any of these recoveries. I also note they can't deal with selinux contexts, apparently. I don't think the new cm rom gives as much flexibility as TWRP or even CWM, except that it will reboot into the bootloader, but it would be easier to recompile ...

Feeling more stupid then usual:
Are these the instructions we use(using the current files) to create the sd card from the linked thread? Thanks
For new Installs:
Download the initial sdcard image
ungzip and write to sdcard using dd (winimage or whatever for those stuck on Windows)
Instert the card into your nook and reboot
Flash the recovery image
Flash cm11 image
Flash whatever other extra things you need like gapps
remove the sdcard
reboot the nook

What are you trying to do--i.e. which rom are you trying to install and what is running now? (I am not sure to which linked thread you are referring) I want to make sure I give you the correct information. You will definitely make an SD Card, (it's how you do it and what you put on it I would like to clarify) And the steps following that will be the same.

I'm using Amaces great current CM MM rom (2/22) just wanting to create the recovery sd in this thread. The link I was referring to was to the verygreen thread in the OP
Thanks

No. Make the SD. Card using the method in the howto thread.
I don't have the link handy...
Basically, format card to full size, set partition to active/bookable, uncompress the download, copy milo first (has to be first directory entry, first file written after formatting).
Then copy the rest of the files.
That gives an SD card that boots to recovery that can be used to flash/backup/restore EMMC.

Thanks ST Dog, just what I needed

New Sd Card recoveries available:
I have built new versions of the recoveries by @amaces in the OP.
I have fixed a few menu issues, e.g. the correct message about which recovery you choose will now come up and the the proper default (TWRP 3.0.0-0) will be highlighted. I ihave ncreased the amount of time you have to press the n (nook) key before the recovery defaults to TWRP (3.0.0-0) , and I have compiled a new version of TWRP (3.0.0-0). The older TWRP and CWM recoveries are the same: be aware that with CWM, if you have formatted data/and or cache with f2fs, CWM will throw off error messages that it cannot mount those partitions, (or wipe them), but you could still use it to install recoveries or zips. Opengapps is now recommending TWRP for installation.
the necessary files are available in two formats -
1.-a zip of a directory containing seven files. You need a fat32-partitioned and marked-bootable empty sdcard on which you copy the MLO file first, and than the remaining files in any order. You can then add whatever installation files you want to play with. You can add whatever zips/ .img files (with twrp) you wish to flash to the card.
2. -A zip of an .img file, which can be written to any unpartitioned card which is 4G or larger. (I understand that this .img may be necessary for mac people, but it also works for me from UBUNTU)
The Nook HD hummingbird version of this works fine for me. And although I don't have an ovation, a couple of intrepid testers have tried this and found that is works.
These are now available on Android File Host:
hummingbird
ovation
I will monitor this thread for problems at least every couple of days : if you mention @belfastraven in your message I will be notified. Please don't bother @amaces who has greatly helped me for with what are now MY mistakes .
In the near future I intend to increase the time you have to press the n(nook) key further, and to put up a version of TWRP 3.0.0-0 that can be used with a mouse, in case of touch screen problems.
here are now additional zips for both Hummingbird and Ovation that will allow you to boot recovery with a mouse and use the mouse to navigate in TWRP3 (in case of broken/malfunctioning touchscreen). If you already have one of the other recoveries set up, you should just be able to replace the kernel, or the kernel and ramdisk file (which is actually TWRP3 here) to achieve this result . You need to have a USB_OTG mouse. (that is, you need to use the nooks charging cable and an adapter to connect the mouse) I have forced USB-HOST on in this particular kernel. These devices don't charge with USB host forced on, I believe, so I wouldn't recommend making this a permanent option if you ever charge your device in recovery.
The ovation version has not yet been tested, but hummingbird works well.

I'm going through OP's stuff, including his guide on CM 12.1. I picked up a free Nook HD from a coworker that currently has CM 10.2 and CWm 6.0.3.2 on it. Should I be using the TWRP and CM 12.1 builds in this experimental folder with the same installation guide or should I be using the stable builds in the hummingbird folder?

Can anyone help me replacing cyanoboot with unit? There's no clear indication of which files to use for the bootloader replacement. Thanks in advance for any and all help!!

decrypt /data

move fstab using official recovery ( adbpull /vendor/etc/fstab.kirin970 and fstab.kirin970.data - remove "avb" and encryption from userdata, replace the encryption line on data with 'encryptable')
format /data in unofficial recovery
install magisk in official recovery
for some reason it only works in that order, if you try and do it all in official or unofficial recovery it doesnt work and magisk recognizes encryption on data.
after each step reboot bootloader and flash respective recovery, then fastboot reboot unplug and hold power and vol up to go straight into recovery and continue, if you boot you have to start over)
when installing magisk zip you should see that it doesnt say keep force encrypt.
and if you go in settings you have the option to encrypt.

Hi there
I´m struggling to get lineage 15.1 to install without google framework errors
You mention offical and unofficial recovery. I guess you are talking about twrp
when you say move fstab do you mean remove?
Could this encryption be my problem with lineage and gapps not installing as it should?

After you install lineage format /data that should work
Totally irrelevant to OP

If i hadn't tried that i wouldn't ask here.
Not TOTALLY irrelevant, as my question is about the official and unofficial twrp having trouble mounting and wiping before flashing rom..
Please stop trolling

If you format data, isn't the device going to be empty?
Only time I've done this before I had to copy a ROM via MTP in recovery and then flash with no Verity.
So forgive me if I'm wrong but if I format data, won't I end up with no operating system?

/system is where the system lives

Noting wrong with formatting, you will lose all apps and data though

Legend, thanks for clearing that up.
:good:
I know off topic, but out of interest with the p20 pro, if you did find yourself with no OS how would you get back to a functional phone?
There's no custom ROMs to flash, just never been in this situation before.
Hypothetically

You can use hurupdater and download the firmware from firmwarefinder on your of
Happened a lot of times for me

Just as a headsup, you dont need to decrypt anything when you just wanna do some changes once and are proper admin level on your desktop machine, ive moved a whatsapp message history from previous phone (also taken from protected space there) to P20P just by attaching it to pc in file transfer mode and then adding myself as full control user in the security tabs of the several system folder properties i went in to, worked like a charm.
The point im trying to make: Android and Windows finally understand each others permission systems (not sure since how long as ive been away from android for a few years) so you can just attach it and use Windows perm system to give yourself access where needed, lots easier & faster then making a bunch of changes to your phone in effect disabling encryption, something you in most cases dont really want to do permanently anyway, so this is a nice workaround that doesn't touch your phone's encryption settings but still lets you mess about with system files.
Just my 2 cents.

I did everything step by step, the encryption is gone and yet I still get that stupid permission denied error when I try to do a backup in TWRP. So. F*cking. Annoying.
Update: when I press the "Install" button in TWRP, it shows giberish, but if I go to Advanced>File Manager everything has it's proper name. WTF?!
Hmmm, If I don't tick "Vendor" in the backup, I get this error:
Can not create 'data/media/0/2021-01-20--07-26-51' folder (No such file or directory).
Failed to make backup folder.
Update on update: oof, now everything that's in the internal storage is gibberish, even in the OS.

[RECOVERY] - TeamWin Recovery Project [REDFIN] [OFFICIAL]

[RECOVERY] TWRP 3.6.0_11-0 - TeamWin Recovery Project
Introduction:
Team Win Recovery Project or TWRP for short, is a custom recovery built with ease of use and customization in mind. We started from the ground up by taking AOSP recovery and loading it with the standard recovery options, then added a lot of our own features. It's a fully touch driven user interface , no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.
Key Features:
Touchscreen driven with real buttons and drag-to-scroll
XML-based GUI that allows full customization of the layout true theming!
Settings are saved to the sdcard and persist through reboots
Ability to choose which partitions to back up and which to restore
Ability to choose to compress backups now with pigz (multi-core processor support for faster compression times)
Onscreen keyboard
Easy selection of internal/external storage
In addition to the above new features, TWRP features a scripting engine that allows an app to send commands to the recovery for the recovery to perform during startup. We call this scripting engine OpenRecoveryScript. This engine will be put to use immediately in the GooManager app. GooManager will be able to install recoveries automatically for most supported devices. The app will also let you choose to install multiple zips from within Android, wipe, and run a backup.
We are looking for other talented developers, themers, and device maintainers if they are interested in helping with a free, open source project.

You need to install a kernel with built-in touch drivers such as ElementX-P5.
First, install ElementX-P5, the use the install ramdisk recovery option in the Install menu to install the TWRP image.

Nice work!
Once the encryption element is fixed I will definitely be rocking this!!

Nice to see this, good job on working TWRP for this Device. Thank you.

Is there only the img build. No zip file? How to stay on twrp without zip?

This boots on a pixel 4a5g, but touch controls and adb do not seem to work. Do you think it would take a lot of code changes to enable it on the 4a 5g? The two phones share kernels for what it's worth.

Its possible to root android 12 with this?

Was able to boot to it on the pixel 5. Look forward to the progress! Thanks!

To get a dmesg, I need to use ADB (which doesn't work while booted into TWRP). So would this capture the info you'd need - boot into TWRP, reboot by holding power button, get a dmesg when it boots?
EDIT: so I'm trying to get it this way but the dmesg.txt comes out blank for some reason

Unfortunately that would be from the android kernel. I didn't realize adb wasn't working for you. Are you using windows?

Thank you for clarifying that it is not flashed to the recovery partition and only booted to when you need TWRP features via
Code:
fastboot boot twrp-3.5.0-0-test1-redfin.img

I was able to get touch working on the 4a5g using these commands:
fastboot flash boot twrp-3.5.0-0-test1-redfin.img
fastboot boot ProtonKernel-pixel5-v1.1.img
ADB Still didn't work. The log said couldn't mount storage. Under "mount" I could check every box except the last two (storage and external storage or sdcard I think).
the backup menu is very different looking than i'm used to. instead of being able to select which partitions to backup, there's only one option - "super (vendor, system, system ext...etc)" The only partition that's not listed there is the boot partition. Also, storage says 0mb . Not sure if it would have backed up anything.
Is it able to make backups on the Pixel 5? Can I get you any info (using the TWRP terminal or file manager mayber) to help development?

The super partition and other partitions you can backup as byte images. However most of these can be restored from the stock firmware. I am working on decryption right now. I am not sure what to do about adb unless you can pull logcat and dmesg for clues for the 4a5g.

Thanks for this TWRP image.
Side loading works.
TWRP does not read the internal storage... Any ideas?

I am not responsible for any wrongdoing by you. Always have ROM stock files. Any error, install stock recovery again.
First you need to unlock the bootloader if necessary! Unzip file attached and look 2 files.
Then, the installation plan:
0) Flash the TWRP with SPFT or fastboot;
1) Enter TWRP IMMEDIATELY without starting in the system, otherwise TWRP can revert to the stock;
2) When asked to enter the password, select Cancel;
3) Load the file with Magisk (look for any magisk19.zip for TWRP and the decryption file for EXTERNAL memory;
4) Flash Magisk immediately and then install the file data_decrypt_Mobiistar_C1_Shine.zip immediately;
5) Make FORMAT DATA - bottom left button - Type: YES. Go back to the TWRP menu;
6) Make Wipe: data, cache, dalvik (reset to factory settings! Save your data!);
7) Reboot to TWRP (password must not ask);
8) Restart on the system, root is received.

thanks bro for making recovery.img when installing magisk 19.zip its giving error on last step failed to mount /vendor/persist (invalid argument). done
after that i tried to install your data decrypt .zip after one reboot to recovery because i have tried before without reboot recovery once so this time rebooted and installed your data.zip file and again on the last step same error as magisk failed to mount /vendor/persist (invalid argument). done
after that i tried to format by typing yes but again same error failed to mount /vendor/persist (invalid argument).done
just to inform you i have formatted phone from inside by turning it on factory reset but nothing happened....and internal space is not mounting i some how managed to install these things via OTG USB but same error again and again. i am attaching screenshot also which i captured from other phone of mine.
kindly help asap

This is Ok. I made TWRP fast and not remember if the stock partitions has \vendor\persist. So if has that's message is normal. Therefore messages about \vendor\nvdata;nvram;nvcfg is normal too. Very pacth zip files can delete that and the device cannot have IMEI.
First: Is good know the file TWRP worked;
- - You can't install any zip without FORMAT DATA first because FORMAT DATA process can view internal storage. If you don't FORMAT DATA maybe the zip file going wrong with MicroSD & OTG.
In this moment you understand: not use external storage! Put zip in the internal storage an try again.
About MTP: Has anything wrong wiht A8.1 & TWRP. Most devices with A8.1 and TWRP do not have access to MTP. I don't know what happens because I don't know why TeamWin was unable to resolve this.
Now you need put zip with adb command (search how to do) or use sileload on the TWRP.
PS: the picture attached by you show about decrypt. In the first moment you need acept modifications and password you press CANCEL.

Look correct app to know about your device: Treble Info
You need try install AOSP 8 & 9: https://github.com/phhusson/treble_experimentations/releases
Look "bugs"; try solving; keep your time with experiments.....
After you can try LOS, RRMix, Havoc, etc.....

The first start need choose the CANCEL. I think you not know about TWRP (unofficial) and the process with device/TWRP without encryption/decryption process.
If you want that so send me some device to develop/have the possibility of getting that option.

As you read, I not have your device in my hands!
Many 32bits and few 64bits devices have problem with touch screen from kernel. That's not my error! It's from device company.
I not know about touch screen work or not since copvaibhav not write about. But I won't fix this. There is also the possibility to use OTG and plug in a USB Mouse to use in TWRP.
There are solutions to fix the touch screen but I don't have the device and I don't have time to do it. Search and you will know. So solve it yourself and thank your self for it.
Ask copvaibhav for more process and using TWRP.

Samsung devices (2) stuck in system boot splash

HI,
I have 2 Samsung devices with TWRP installed, and I can access the TWRP recovery menu. When I install the flash ROM and try to boot, devices are stuck in system boot forever.
Device 1: SM-T800, with LineageOS 14.1 previously. I opened an email and the device got hacked, so I did a factory reset (which failed), then re-flashed the latest TWRP and recovered rescue mode. Now when I flash the Lineage ROM (from TWRP) the device does not boot to system but keeps showing the splash screen. I think the hack might have placed immutable files under system. could I format this partition to zero it out via ADB? What other choices are there?
<EDITED>
Device 2: Galaxy S3 GT-I9300 - I solved this so i removed this section.
Thank you for any help.

Device 2: Galaxy S3 GT-I9300, with working TWRP. This device is giving a "Failed to mount /efs (Invalid argument)" error. The previous setup was shared storage with sdcard and encryption on both internal and sdcard. The sdcard got corrupted, hence the error. This post suggests running
Code:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1
but the device does not have identifiable boot device under /dev/block. I think this might work if I can identify the boot partition name?
Thank you for any help.

Flash a custom ROM for i9300 via TWRP. Download a custom ROM for i9300 and the appropriate Gapps to go with the ROM, store them on external sdcard. When you are in TWRP, before you flash your ROM, select the "Wipe" option, then select "advanced wipes", on the next menu, choose the system partition, data partition, cache partition and dalvik cache partition then swipe the slider to wipe. Then go back to home screen in TWRP and choose the "Install" option, then choose your ROM file and your Gapps file then swipe to flash. When the flash is finished, select the "Reboot system" option and see if it boots into system.
If that doesn't work, we will take some steps further back and try starting from the beginning.
Keep in mind that some of the custom ROMs for i9300 may have a different partition structure and partition sizes than the stock firmware for i9300 has and may require resizing certain partitions such as the system partition by flashing a custom PIT file like the Galaxy S2 had to do before it flashed certain custom ROMs.

Hi, thanks for the input.
* I had already solved the GT-I9300 issue before your post (I should have added to thread rather than edit the original post). I solved issue with that device by including system partition in the wipe.
* For the SM-T800, I used a LineageOS-14.1 that I had stored somewhere. That also did not work, until I only flashed Lineage and did not include any GApps. If I really need it, I can always flash later. I assume the latest GApps 7.1 build conflicts with older ROMs.
An unexpected problem was the lack of current ROMs for the 2 devices. SM-T800 has nothing other than last build Lineage-14-1-20190205. The I9300 has several unofficial ROMs floating around for newer Android versions, but they are all debug/dev builds with enabled options that drain the battery very quickly.
If anyone comes across a decent ROM for either of these devices please LMK. Thanks.
