Custom 21.329.01.00.00 firmware and 17.100.19.01.00 web interface for E5770
The firmware is based on the original global firmware version 21.329.01.00.00. It can be installed on any technological firmware, or updated from a modified firmware.
Flash using balongflash (Windows, Linux).
Attention!
This firmware can render your device unbootable! Use it only if you are aware of all the risks and consequences. In case of any problems, do not wait for help, you're on your own. Do not install firmware by non-tech-savvy people request, and do not sell routers with this firmware preinstalled.
Changes:
Firmware digital signature verification in the firmware server is disabled
Added support for IPv6 on mobile networks (disabled by default, could be activated "ipv6" script)
ADB installed and Telnet activated (disabled by default, controlled from the OLED menu)
The stock versions of busybox, iptables and ip6tables programs are replaced with full-fledged ones
The "atc" utility is installed to send AT commands from the console
Installed "ttl" script for modifying (fixing) TTL (for IPv4) and HL (for IPv6)
Installed "imei" script to change IMEI
A local transparent proxy server "tpws" and a script "anticensorship" are installed to circumvent censorship to sites from the registry of prohibited sites in Russian Federation (IPv4 only)
Added DNS over TLS resolver stubby (version 1.5.1, compiled with OpenSSL 1.0.2p) and DNS-level adblock (IPv4 only)
Added extended menu on OLED screen
Added RNDIS and ECM Ethernet switching functionality without a switch program on a computer
All NVRAM items are unlocked
AT^DATALOCK code is disabled
Added kernel module TUN/TAP (for OpenVPN and other programs)
Added OpenVPN (version 2.4.6, compiled with OpenSSL 1.0.2p) and scripts for DNS redirection
Added curl (version 7.63.0, compiled with OpenSSL 1.0.2p)
Added EXT4 kernel module and swap support
Added script for installing Entware application repository
Added script "adblock_update", for updating the list of advertising domains
Added script to change MAC address of Wi-Fi in Extender mode (script "wifiext_mac") and USB MAC addresses (script "usb_mac")
Removed mobile connection logging (mobile logger) to extend flash memory lifetime
Multilingual web interface with GSM/UMTS/LTE band selection menu
The extended menu on the OLED screen allows you to manage network mode (LTE/3G/GSM), TTL modification, circumvent censorship, ad blocking, IMEI change, USB composition, control access to the web interface, Telnet and ADB.
TTL modification and IMEI change require a reboot. The remaining menu items are applied instantly.
To activate extended menu, press left (WPS) button 7 times on Wi-Fi information screen.
The "anticensorship" script helps to bypass Deep Packet Inspection (DPI) systems on some operators in order to bypass web site blocking. It starts the local proxy server from zapret complex https://github.com/bol-van/zapret, modifying the packets in such a way as to complicate their analysis, and redirects all traffic to ports 80 (for HTTP) and 443 (for HTTPS) to local proxy. The proxy server works autonomously, without any third-party server on the Internet. It is recommended to use it in conjunction with DNS over TLS, in order to prevent possible DNS hijacking by the operator.
Advertisement blocking is performed on DNS level with dnsmasq DNS server. It works with DNS over TLS as upstream, requests for which are redirected if the corresponding menu item is activated from the OLED screen. EasyList and RuAdList https://forums.lanik.us/viewtopic.php?f=102&t=32524 from raletag and AdAway https://adaway.org/hosts.txt are used as an ad lists.
Ad-blocking at the DNS level works worse than full-fledged content blockers in browsers (AdBlock, µBlock), but it works on any device and in any program without additional settings.
You can also control ad blocking with the "dns_over_tls" script.
Domain lists could be updated using "adblock_update" command.
Entware application repository allows you to install additional Linux software from the armv7sf-k3.2 entware repository http://bin.entware.net/armv7sf-k3.2/Packages.html, using "opkg" package manager used in open source firmware for OpenWRT routers. Entware is installed using the "entware install" command. Entware files are installed in /opt, which is mounted in /online/opt. You can install many programs on 30 MB free space after installation on /online partition.
The router and Entware environments are independent of each other, the installed Entware software cannot be called from the router's environment, and the firmware programs and scripts cannot be called from the Entware. This was done to ensure that the installed packages would not conflict with files in the firmware.
To gain access to the Entware environment, use the "entware shell" command, to exit, type exit (or press CTRL+D).
Entware is designed for advanced users who understand how to customize and use installable programs. About 15 MB of free RAM is available in the router, the launch of heavy programs can lead to the crash of important services for the router (especially when DNS over TLS is enabled), remember that.

Thabks for the share. Is it possible to unlock all bands to use it anywhere in the globe?
link not working
Hi I tried downloading the modded firmware but it only goes to 20% every time then hangs. can you fix please or host somewhere else.
many thanks

No, that's a hardware limitation. Different hardware modifications have different radio hardware. They could be converted by soldering some components though.

You can download ZeroNet and download it from there, because ZeroNet to Internet gateways are unreliable.
E5770 FW version 21.327.01.00.1133, 21.200.19.01.405, 21.318.01.02.07 downgrade to technological 21.180.99.10.00
This special firmware allows installing technological firmware on firmware versions mentioned in the title, without entering OEM code (AT^DATALOCK), and without using test-point (needle method).
Technological firmware allows installing any other firmware (even with incorrect or corrupted signature), without any restrictions.
WARNING: If you flash this firmware, you won't be able to revert your old firmware version because there's no official firmware files of these version available in public access. You can install any other firmware though.

Probably something with Qualcomm chipset, which I'm not savvy in.
It depends on LTE bands or countries you're planning to use the device.

Hi OP,
my device is stuck on download mode.
can you please explain the flashing steps for the custom firmware.
As per your Read-Me the firmware should be flashed by balong_flash FLASH_FILE.BIN command.
Whats unclear to me is which file is to be flashed first. There are 2 .bin files in the custom firmware archive.
It will be a great help if you can give a step-by-step guide.

First of all, to install custom firmware you need to install technological firmware somehow. You can't install it just by flashing, it will require flash code which cannot be obtained easily. To bypass flash code check, I made downgrading firmwares for several firmware versions. You need to install downgrading firmware for your current firmware version, which will downgrade to technological firmware, and from technological firmware you can install any firmware, including custom one.
What exact steps did you perform, what exact result did you get?

Is there any way to activate Samsung SSecure (or other apps) without root? (I know we have secure folder but i want to use native AppLock which is more practical.)
Related link:
https://forum.xda-developers.com/android/general/samsung-additional-features-t3930900
I have no root (and I don't think of rooting) but i changed CSC, TUR to THL for native call recording, it is working perfect. With same way, can we get these features (at least AppLock) by modifying the CSC or something similar?
Thank you..
Hello, I am a Korean user who likes htc very much. I have shared how to activate tta-volte volte to the developer of gsi Viper, who develops a lot for htc products, although my English is not good enough, and I'll give you some information now.
It has been 10 years since HTC already closed its business in Korea, so there is no Korean telecommunications company or supplier file, and it does not sell. It's sad. Anyway, let me explain. Originally, HTC products were not allowed to open Qualcomm ports, but only U12+ can open Qualcomm ports
(adb shell - su - setprop sys.usb.config rndis,diag,adb)
Volte in Korea is an independent tta-volte method, so I have the same Qualcomm Snapdragon 845 and I extracted efs files and mbn from Sony Xperia xz2 Korean version firmware, which was officially released in Korea, and pasted them using Qualcomm epsproler.
If the communication company you are using has its own standard like Korea, you can replace the efs file in the same way as I do, and if that doesn't matter, please read the following immediately.
Note the HTC system folder. There is a secret in the system custom folder. First, if you look at customize - MNS folder, it's a number.I see xml. There is a secret in that number. The number is the carrier code. It's very simple. I found this. It was such a pleasure. Please correct the xml title. For example, it is 45008 because it is KT(koreatelecom) mcc:450 mnc:08 You can check the carrier's mcc, mnc(apn) and modify it to 45008.xml and if you look in the custom folder, there is mns_map.xml. Edit the file as text If you enter the 45008th place you changed earlier and reboot, you will be able to create a volte active menu on the existing phone app setup screen.
This is all, simple. When you add an xml (app:mcc+mnc) title in the mns folder, write and save the number that was just added in the custom folder-mns_map_xml text editor, and reboot, the htc phone app settings show the volte activation menu, and there are no other changes to the build-prop In the case of Korea, it was necessary to modify the efs file because it is volte in a nonstandard way.
Modifying directly to root file editor without module It's very simple. My last hope is that volte is possible at gsi and that htc will continue to announce new flagships and that htc users are all healthy, thank you.

Dear htcmage,
Can you post the detailed step by step on how to do this?
Regards,
Brian
I looked around a lot on the forum and from what ive understood theres a way to do it by changing the csc or smthg. But im an absolute noob and dont know what any of this means. Can somebody give me a ste by step guide on how to enable the e-sim. I currently have a SM-G985F/DS
On pc: download samkey from org site (just google it)
Download and install samsung usb driver
Buy credit (you need only one)
On your phone:
Enable developer mode and adb
Remove sim card and all sort of lockscreen
Connect phone on pc, open samkey app and click on read info (phone will show up a popup asking for some permission, just consent)
Now looking on samkey interface you will see a text box named csc. Wrote there a csc having esim enabled (like btu) and click on wrote csc.
Just click there and you are done.
This will work only if you have dual sim variant, then should enable esim. If you have single sim variant, so you will have only csc changed without esim enabled
Is there no other way to do it without paying more money. Im aldready tight on cash.
I really cant cough up the money for credits.

If you are already on lastest security update no.
If you dont ever update your phone and your firmware is on bit 2 or lower, there is a modded theme that open a secret menu to change csc for free.

Flash Magisk through twrp unless you have it.
Then flash csc features enabled .zip from the link below
https://forum.xda-developers.com/ga...agisk-module-decodedcscfeaturesfiles-t4082445
some background,
I am after thorough tests on the topic of how it works VoLTE and VoWiFi And what causes it to be activated in some providers and in some not.
The source from which I drew all a lot of information was: https://volteromania.blogspot.com/p/samsung-voltevowifi-settings.html?m=1
Actually, I followed all the steps but got stuck on the most important part.
In order to start communication for VoLTE It is necessary to define a profile IMS.
Samsung chose - unlike APN Not to allow any user to create such a profile, but the profiles are inside files json in the file /system/priv-app/imsservice/imsservice.apk
I am very interested in trying to edit the files json These, but all my attempts were unsuccessful.
I have a Samsung S21 ultra Rooted, on which I perform the tests.
I can't edit the APK without hurting him. Any change in it causes the application not to load - and completely disables the service IMS and the registration.
The files I want to edit are in
/priv-app/imsservice/imsservice.apk/res/raw
It's files json simple.
Maybe someone can help me?
im curruntly trying to enable Volte on Samsung SM-N920L korean phone in defferent region..no luck..im rooting for you..if any succuss please let we know too..
I gave up.
This is Samsung's behavior on purpose to make consumers have to replace the phones.
Anyway, in the technical part,
In Android 13, in my opinion, this is not completely possible, since every change in the application damages the signature, but even in older versions it is necessary to change the Java code as well, And as you know it is compiled.
I spent many hours on this, with several devices, I purchased a Galaxy 7 for the tests, and I failed.
I do not know if this still works, but on my SM-9700 (HK) with Android 10 I made VoLTE work in Germany by copying the "product/omc/DBT/conf" from a SM-970F to the corresponding TGY directory of the SM-9700.
I was able to run volte on the galaxy s7.
It requires a lot of changes.
Including in the smali files of the application imsservice.apk and it was a nightmare.
In my case I had to add a brand new provider that didn't appear anywhere, maybe that's why everything was complicated and maybe if it's a defined operator and just enabling the option is simpler.
Anyway,
It really wasn't easy, but I had most of the information from the first post I wrote, but I was also able to find a lot on my own.
It is not easy.
Maybe Samsung will release the source code (including java) of the imsservice.apk application and then it will be easier..
Have you ever tried just copying the content of the conf directory from another phone?
This made VoLTE work on my Hong Kong Note10 (Snapdragon) in Germany.

I have nowhere to copy. I don't have a phone that works with the same carrier I wanted to test. I had to write all the settings myself.
Which carrier do you need? We (the forum) might copy it for you.

Hi,
I would like to have your guidance
I have a LG v60 L-51a docomo model where field test option (hidden menu ) is disabled.
I am unable to enable volte in India to use jio.
Searched various options seems no way out. However i was able to locate hidden apps by using 3party launcher app. LG ims. But unable to launch hidden menu to changed ims settings. Help me to by pass this application to enable volte.
I don't know if this will help anyone, or if anyone can help me, but...
SM910v, (verizon wireless) with T-Mobile SIM
6.01 Marshmallow (please read the rest anyway)
4G/LTE Data works.
Voice calls fall back to 2G/Edge, ie no VoLTE.
-------- HOWEVER -------
Changing the sales_code.dat from VZW to TMO enables VoLTE, and it works great.
(it breaks the settings pages, though, so it's not a solution)
When sales_code is VZW, then IMS Settings-->IMS Information:
All are "false", Registration Information is "no profile is registered", although the profile "T-Mobile VoLTE/RCS" is available and status is 'on' in the Manage IMS Profiles page.
I can not find a way to 'register' it.
When sales_code is TMB,
then, in IMS Settings-->IMS Information:
All are "true", Registration Information is "T-Mobile VoLTE/RCS",
And, of course, VoLTE works great.
I mention this in this thread because just having the correct profile present & available may not be enough. At least in my case, it appears that the sales_code (or some other CSC function) flips a flag somewhere that allows the profile to become selected/active. I've been trying to find it for six weeks, with no luck yet. Thanks for reading.
