Fun Projects: Ubuntu Touch & LuneOS

v3ritasLeave a comment

Two things I’m currently working on:
– Ubuntu Touch on my old Nexus 6P, just to see how it’s coming along. I did need to reference this comment in order to get mine booting properly.
– LuneOS on my old HP TouchPad… Which is giving me some problems. It started off rough because I was trying to find some files that were released between 2011-2014, & then trying to get them running… Then once I finally got that done, I still wasn’t able to get LuneOS to boot. Here are some of the files I collected while working on this:

webOS Resources

Just making note of some webOS tools \ resources that could be useful as I start playing with my HP TouchPad (Tenderloin) again. Specifically, I want to install LuneOS on my device.

Malwarebytes Labs: Relax. Internet password books are OK

Source: Malwarebytes Labs: Relax. Internet password books are OK

So this was posted on April Fools’ Day, but I do believe it’s a serious post & I agree with the content. The author brings up the point early: Whether using a physical password book is a good thing depends on your threat model & risk. If you are not good with computers & can’t figure out how to use a password manager (see some of my other posts about passwords: Don’t Change that Pa$$w0rd, FINALLY: A Good Password Management Article, & ANOTHER GOOD article about passwords) & you don’t have to worry about someone you live with abusing access to the book, then this is a great way to store passwords without remembering them or re-using the same one over & over. Having the details saved in a book that’s kept in a drawer at your desk is a good way for some people to store different passwords. And it would obviously stay safer if the book stays at home, versus keeping it with you at all times & potentially losing it while out & about. That of course leads to other questions like “What do I do if I am away from home & need a password?”, but that will have to be answered by the user: Is it worth carrying the book with you at all times or is it really something that can wait until you get home & can access the book.

Reasons why I run a network-wide adblocker…

v3ritasLeave a comment

In the last 24 hours…

Screenshot from Pi-Hole dashboard

For anyone else looking to run a network-wide adblocker, I recommend Pi-Hole. I have also recently started testing out AdGuard Home & will see in the long run if I decide to switch, or just leave it as a backup.

I run Pi-Hole as my primary DNS & DHCP server with an excessive number of blocklists (totaling ~4.5m blocked sites) & have no issues with it. I only started looking into AdGuard Home after a resource issue on my original Pi-Hole (it seems when I added Resilio Sync to my Pi, the system would lock up). So, I decided to replace RasPi 3 B+ with a RasPi 4, 8GB, & turn the original 3+ into the secondary AdGuard DNS server.

I definitely do like the AdGuard Home interface better than Pi-Hole, but will see if there’s actually enough there that will make me want to switch off Pi-Hole once & for all, or as my primary.

Goodbye Google Fi & Android

v3ritasLeave a comment

I find it pretty ironic that Google Fi is the reason I’m leaving Android as well. Whether it’s because of an actual Fi issue or juts a tower issue in my area, that caused me to finally switch off of Fi (something I’ve been meaning to do anyway), & I decided to switch to an iPhone to get more use out of my phone, but also so I could actually still communicate with some people on iMessage.

I guess I’ll also be looking into jailbreaking some more, especially since the phone I’m using for now is vulnerable to Checkra1n.

iOS14 Charger Connect\Disconnect Sounds

v3ritasLeave a comment

This seems to be very popular with the release of iOS14, & I’m writing this up as a personal reference so I don’t have to continue to watch the great setup video that u/zeeshan_02 posted on Reddit: Beginner’s Guide on Playing a Custom Sound when Connected to Charger!

Shortcut 01: Encode Audio
This converts a sound file (in my case I was using an MP3) to Base64, for later use by the next shortcut:

“Encode Audio” shortcut

Shortcut 02: Charger Connected
Sound that will be played when the charger is connected. The base64-encoded text should already be in the clipboard from the step above. You just have to paste that into the Text field:

“Charger Connected” shortcut

Shortcut 03: Charger Disconnected (Optional)
Can use the same sound for connect & disconnect if you want. I just wanted to have different sounds used. It’s the same setup as above, just using a different Base64 string. If you want the same sound for both actions, you can skip this.

Automation
Setup a new Personal Automation for when your device is connected or disconnected from power, or both, & run the appropriate shortcut for what you’re trying to do.

Automation to play the sounds based on your selection.

OnePlus 7 Pro: Update System Firmware on Custom ROM

v3ritas5 Comments

Follow up to the OnePlus 7 Pro: LineageOS+MicroG post, where I mentioned I would have to update the Bluetooth & Modem firmware on my device. This fortunately went as smoothly as the LineageOS+MicroG install, so I’m very happy about that.

The first step was downloading the latest OxygenOS ZIP through this post: XDA Developers: [ROM][STOCK][FASTBOOT][OP7P] Stock Fastboot ROMs for OnePlus 7 Pro/ 7 Pro 5G by mauronofrio. The specific ZIP i pulled down from Android File Host was “10.0-GM21AA-OnePlus7ProOxygen_21.O.20_OTA_020_all_1909172051_db7a3f61-FASTBOOT.zip”. From there, it was just a simple matter of extracting that, images.zip, & flashing the bluetooth.img & modem.img files:

OnePlus 7 Pro: LineageOS+MicroG

v3ritas1 Comment

After a full weekend of originally getting CrDroid on my new OnePlus 7 Pro a few months back, I decided to switch to LineageOS+MicroG because I was never able to get location working on CrDroid. This was mostly due to the changes in Android 10, but when I was still unable to get it working with the new UnifiedNLP package, I just decided it was easier to switch & settled for reinstalling MicroG, which I had avoided on CrDroid because I wanted to avoid as many Google services as possible.

Since I had so many issues getting CrDroid setup in the first place (mainly due to me lack of experience with A\B partitions & not knowing I needed to flash OxygenOS first, then the ROM on top of it), I wanted to keep track of the exact steps I took to get LineageOS+MicroG so I could follow it the next time I decide I want to try a new ROM. Posting it here just makes it easier to come back to & maybe it will help out someone else.

First step was just backup & prep: Making sure I had backups of my messages, F-Droid repositories, 2FA tokens, as well as my list of installed apps.

One thing I was surprised at for the installation was that I wasn’t expected to flash an OxygenOS ROM first… Below are the two “guides” i followed:

OnePlus Forms: [ROM] LineageOS | OnePlus 7 [17.1][Android 10][OFFICIAL]
This one specifically included when to flash Magisk:
XDA Developers: [ROM]-[10-04-2020]-[microG] Unofficial LineageOS 17 w/ microG support by gigatex

Flashing Recovery: I thought this was one place where I had issues, but that may have only been on the Essential Phone, where I couldn’t boot recovery. that did work on the OP7Pro:

➜ OP7Pro adb reboot fastboot
➜ OP7Pro fastboot devices
0810d6ea fastboot
➜ OP7Pro fastboot boot twrp-3.4.0-0-guacamole.img
Sending 'boot.img' (31704 KB) OKAY [ 0.742s]
Booting OKAY [ 0.106s]
Finished. Total time: 0.886s
➜ OP7Pro

Once I was booted into TWRP I formatted DATA & pushed the LineageOS+MicroG & TWRP installer ZIPs, then rebooted to recovery again (without flashing anything). I ended up having to push the two ZIPs again because they were not present on the “SD Card” after the reboot. After pushing the files again I flashed & rebooted the system to complete setup.

An issue I did run into with Magisk appeared to be due to the A\B slots again. The fix seemed to be flashing when getting into TWRP, then manually changing the A\B slot, rebooting to recovery, & flashing again. Just a simple “Reboot > Recovery” didn’t change the slots.

I did just attempt a system update yesterday, & it was successful, following the same process I took during CrDroid: Use the internal updater, but DO NOT REBOOT through the updater. You have to go into Magisk Manager > Magisk Install > Install > Install to Inactive Slot (After OTA). You can then reboot & will still be rooted with Magisk.

I will have another update shortly about updating firmware, since I just noticed this morning that Bluetooth will not stay enabled. While on CrDroid the fix seemed to be flashing Bluetooth & Modem firmware from an official OxygenOS update.
