LG G2 D802 boot loop fix

Problem:

LG G2 D802 was rooted and a custom recovery package TWRP installed.
OTA says there was an update.
After applied, it goes into an endless bootloop - always stayed in TWRP.

Fix:

http://forum.xda-developers.com/showthread.php?t=2451696

Install Android SDK that will give you access to ADB shell tool.

Run the following commands:

 
adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

Then reboot the phone within TWRP.
This has fixed my G2 twice.

ISPConfig / Pure-FTP / SSL (TLS) setup

ISPConfig comes with LetsEncrypt integrated in its panel for web domains. However, it does not automatically use the SSL cert for FTP service (PureFTP). This post describes the steps to enable the support. 1. We need an FQDN so that Lets Encrypt (LE) will be able to generate SSL under ISPConfig panel. 2. PureFTP TLS support requires a cert in .pem format which can be generated by leveraging the LE cert generated: cat /etc/letsencrypt/live/mydomain.com/privkey.pem /etc/letsencrypt/live/mydomain.com/fullchain.pem > /etc/ssl/private/pure-ftpd.pem 3. Restart PureFTP so that it will not use the new certificate 4. LE certificates need to be renewed regularly so it is necessary to create a cron job to keep the .pem file updated. Setup a crontab 0 6 * * * /etc/letsencrypt/certbot-auto -n renew --quiet --no-self-upgrade && cat /etc/letsencrypt/live/mydomain.com/privkey.pem /etc/letsencrypt/live/mydomain.com/fullchain.pem > /etc/ssl/private/pure-ftpd.pem && se...

ISPConfig 3 / Mail / Custom mail filter recipe

Recently trying to setup a mail re-direct (or a cc) to an external e-mail address. It is important to first determine if you are running courier or dovecot because the syntax is different. Under dovecot, it should be in sieve syntax. Therefore, under ISPConfig3 -> Email -> Email Mailbox -> Custom Rules, enter: redirect "mail@example.com"; Ensure it is double straight quotes and semi-colon at the end. Wait until the update is done (usually a few minutes) via the cron jobs of ISPConfig3 updating the /var/vmail/domain/username/.sieve

Ubuntu 16.04 and ISPConfig 3.1 - stopping ClamAV

ClamAV requires quite a bit of resources to run in the background and this usually slows down the mail delivery. In the ISPConfig 3 (Under Perfect Server setup), clamAV is run within Amavis. Therefore, typical removal of clamAV commands will not remove it. When RAM is really low, Linux kills amavis and this will cause mail not being delivered. Therefore, if we run amavis to manage anti-virus and spam, consider a minimum of 2G or 4G RAM VM/Cloud servers. The steps to disable clamav and amavisd are: (1) edit postfix conf - note amavis uses a special port 10024 and 10026. Therefore, if you are not using these ports, consider closing them in your firewall settings. nano /etc/postfix/main.cf # content_filter = amavis:[127.0.0.1]:10024 # receive_override_options = no_address_mappings (2) Under ISPConfig 3.1, comment additional 2 lines nano /etc/postfix/tag_as_foreign.re # /^/ FILTER amavis:[127.0.0.1]:10024 nano /etc/postfix/tag_as_originating.re # /^/ FILTER amavi...
