Why use third-party firmware?

Read on for more information about the problems this third-party firmware solves, or skip to firmware downloads if you want to get started right away.

History

Several users on the DSLReports VoIP Tech Chat forum discovered how Obihai firmware could be reverse-engineered and updated so that features may be added. The first feature was the update of security certificates on the OBi100/110. Although Google Voice is no longer compatible with 100/110, this third-party firmware extended the life of these ATAs for those who like to use Google Voice. (The 100/110 can still be used with any non-Google BYOD VoIP provider.)

History

On 19 June 2018, Google decommissioned XMPP servers so OBi100/110 don't work any more, even with the third-party firmware. While it's possible to make the 100/110 work, it's not that easy. If anyone likes to work on this project, please discuss it at DSLReports.

Today

Still are good features in the third-party firmware for OBi2/3, OBiPHONE, and now OBi5. Also adds a SSH server, allows unlocking of vendor-customized devices, and allows Caller ID contact list.

Do I need flash programmer?

Not any more. Some very intelligent users developed a firmware that is a direct replacement for the official firmware and can be easily installed using traditional methods.

Downloads

arrynrob - for OBi200/OBi202/OBi300/OBi302 (Untested: OBi212. Did you test it? Please discuss at DSLR.)

If your current firmware version is less than 5853, just flash arrynrob9 directly.
If your firmware is 6259 or greater, you must install stock 5921EX first, then install bypass-uboot-mod.
If your firmware is >= 5853 and < 6259, you must bypass uboot by installing bypass-uboot-mod. Then, you can install arrynrob9. DO NOT flash bypass-uboot-mod from 6259 or above, or you will be going to recovery mode (which also allows you to flash any firmware you want, but it just doesn't look as cool).
md5sum OBi302-3-2-2-6259-signed-fw-bypass-uboot-mod.fw = 59229dd211edb52d9f2e49729cee9794

Please read above installation instructions before install arrynrob9!
Download - OBi2-3-2-2-5921EX-arrynrob9.fw
md5sum OBi2-3-2-2-5921EX-arrynrob9.fw = 40896aa857d6509ac196e82525801b4c
Changes:
  1. enable dropbear ssh server. default root passwd = "obi".
  2. patch obiapp to bypass "zero touch" forced configuration. added clear_zt_params util to clear old zero touch params
  3. patch obiapp to use /scratch/contacts.xml for caller id number to name translation lookup.
  4. patch obiapp to bypass signed firmware check when loading new fw
  5. patch obiapp to bypass GVSIP provisioning lock
  6. patch obiapp to bypass 30x models GV initialization block

taoman1 - for OBi2000 series

Installation instructions:
  1. To go to a modded fw from stock, flash to OBi2000-6-2-3-4907-signature-bypass.fw first.
    md5sum OBi2000-6-2-3-4907-signature-bypass.fw = 24d0bcad8601d96b5f6b05120181c967
  2. Next, install OBi2000-6-2-3-4983-taoman1.fw.
    md5sum OBi2000-6-2-3-4983-taoman1.fw = 96f1050de137bc8c2737500b987c4337
Changes:
  1. enable dropbear ssh server. default root passwd = "obi".
  2. patch obiapp to bypass "zero touch" forced configuration. added clear_zt_params util to clear old zero touch params.
  3. patch obiapp to bypass signed firmware check when loading new fw
  4. patch obiapp to bypass GVSIP provisioning lock
Mod implemented using a new technique of adding code to the padding at the end of an ELF segment instead of overwriting functions inline, because this fw uses oauth in more places.

olisom - for OBi1022/OBi1032/OBi1062

Installation instructions: If you wish, try to skip directly to Step 3. If you have an old firmware version, it may work.
  1. First, ensure you are not using build 4858. If you are, then flash to different version such as OBiPhone-5-1-11-4983EX.fw
    md5sum OBiPhone-5-1-11-4983EX.fw = b10d7c73d8898028fac8698e6d5516b6
  2. Next, install OBiPhone-5-1-11-4858EX-noshell-signed.fw
    md5sum OBiPhone-5-1-11-4858EX-noshell-signed.fw = 123bd1842a64ab967644e34e6a7d144c
  3. Now, you may install olisom firmware: OBiPhone-5-1-11-4858EX-olisom5b.fw
    md5sum OBiPhone-5-1-11-4858EX-olisom5b.fw = 9eef1e893b7835521a13bc5f328afe0e
Changes:
  1. add dropbear ssh server. default root passwd = "obi"
  2. patch obiapp to bypass "zero touch" forced configuration. added clear_zt_params util to clear old zero touch params

  2. Next, install OBi500-4-0-5-5903EX-ssyspro5.fw
    md5sum OBi500-4-0-5-5903EX-ssyspro5.fw = 1949638ca7161904fbda0da795b8eec9

Disclaimer

These firmwares, like the official Obihai firmwares, are provided without warranty. Standard precautions apply, such as do not install firmware over a wireless network connection.

Support

Where to get support

Obihai does not support OBi100/OBi110 ATAs (and doesn't really support their other products either).

VoIP Tech Chat

DSLReports hosts one of the busiest VoIP forums on the internet, which is the forum where this firmware was first discussed and published.

OBiTALK Community

The OBiTALK Community is a forum specific to users of OBi products. It has largely been abandoned by Obihai but the users are sometimes helpful.
