Acceleration of 3G CDMA Intertelecom (Ukraine)
Good afternoon, I requested your script, everything went well, without a script the speed is 0.35 - 0.64 mb / s (3G CDMA), after the script - 0.9 - 1.04 mb / s. Many thanks for your hard work !!!

Samsung Galaxy S4 Mini

Hi, on my sgs4mini 9192 android 7.1 phone, the first two methods only made it worse, and the third one made the wrong link.
Standard: Download 6.22, returns 3.59, ping 34.
Method 2: Download 3.47, return 1.16, ping 31.
Method 1: Download 2.82, return 2.57, ping 31.

For the result, thanks to u.asd_13.

A bit of theory and observation

The article on lifehacker refers to the sourcexdaas well as usedJacobson’s TCP / IP header compression method.
The method is based on configuring a PPPD daemon - a Point-to-Point Protocol Daemon daemon. You can read more about this.here.
On my 4G smartphone, the data download speed increased only in the 3G connection mode, and in the 4G connection mode it remained equal (within the margin of error, of course). The change in speed in the second generation network did not check, because my operator in this range does not serve.
That is, the acceleration is relevant only to those who have the network at least sometimes works in 3G connection mode.

If interested, welcome to the instructions.

Disclaimer

I remind you that you perform all actions at your own peril and risk; no one is responsible for their consequences. It is recommended that you first read the instructions completely, evaluate your capabilities, and then proceed with the implementation.

Installation Instructions

After updating the system, you must reinstall! Read more inUseful ->Note on the location of the file in the system.

Using customrecovery(script version 16.8)

If there is Ruth access, then you should first try the Ruth method. there ismessage, that after flashing the archive, the device stopped loading! It is strongly recommended to make a backup!

1. Measure the speed of the 3G connection before executing the instructions (I like to use the site2ip.ru/speed), write / scroll / remember the result.
2. Save fileupdate-speed-up-3g-16.8.zip(176.22 KB)
on the device and flash it through the recovery.
3. [optional] Just in case, after installation, check for the presence of a fileoptionsin folder/ system / etc / ppp, if it was not copied there, the acceleration will not work (please informto mein QMS).
4. Check the speed increase in 3G connection mode: measure the speed at the same place where it was measured for the first time, and compare it with the previous result.

If there are no special changes, you can try another installation method or go to the removal instructions :(

Results sent to QMS:
This method works on: Xiaomi Redmi Note 3 Pro with TWRP 3.0.0-0 recovery.
This method does not work for: Lenovo P70-A with TWRP v3.0.2.0 recovery.

Instruction written by userSerVBul, inspired by the way uv.alexax66.

UsingROOTaccess

Under the spoilers are explaining screenshots (for example, Root Explorer).

1. Measure the speed of the 3G connection before executing the instructions (I like to use the site2ip.ru/speed), write / scroll / remember the result.
2. Saveoptions.zip(398 bytes)
on the device.
3. Unpack the archive and move the fileoptionsfolder/ system / etc / ppp.

To item 3

The file is copied to the desired folder:

4. Change permissions for this file: in the "Read" and "Execute" columns, set three checkboxes each, and in the "Record" column, on the contrary, there should be no checkboxes. Thus, file permissions take the form "r-x r-x r-x" or 0555.

To item 4

In different file managers, changing file properties is done differently, for example, in the Root Explorer you need to make a long tap on the file, click on three points and in the opened window select "Permissions":

The file system may be write protected. You need to enable recording:

We set permissions:

You must return the write protection. Push the button:

The inscription r / o says that the file system is in read only mode - write-protected:

5. Reboot the device.
6. Check the speed increase in 3G connection mode: measure the speed at the same place where you measured the first time, and compare it with the previous result.

If there are no special changes, you can try another installation method or go to the removal instructions :(

Instruction written by userSerVBulbased on lifehacker's instructionsdimgor.

In development: using adb shell; manually using ROOT.

Removal Instructions

Using ROOT access

1. Delete a file/ system / etc / ppp / options.
   
2. Reboot device.

How to measure the speed of the 3G connection

If your device does not work only in 3G mode, measuring 3G speed can be a problem, because device in the testing process can switch to another generation of communication. Therefore, you need to activate the "3G only" mode.
Instruction (on different devices the process may differ slightly):

1. In the call to dial* # * # INFO # * # *(i.e. in numbers*#*#4636#*#*), the test window should automatically open (you do not need to press the call button).
   
2. Select item "Phone information"(if there are several SIM cards in your device, then it may be offered a choice for which SIM to change the settings).
   
3. Scroll and find the drop-down menu under the heading "Set preferred network type".
   
4. Remember that it is selected by default (to return as it was after the test).
   
5. Select item "WCDMA only"(on different devices may be called"3G only", "HSDPA only"...).
   
6. Wait a few seconds for the connection to restart.
   
7. Check connection speed.
   
8. Reset the settings to their original state (repeat steps 1-6).
   

I can add that on my smartphone (Xiaomi Redmi Note 3 Pro) after rebooting, the network type returns to its default position.

Note on the location of the file in the system

Because fileoptions(which runs the acceleration) is in the folder/ systemAfter flashing / updating the system, its automatic removal is possible. Therefore, after each such action, you must install again.

Other ways to accelerate the connection

You can check other ways:
* Method 1
* Method 2
* Method 3 (ADB)
All of them are planned to be added to the header and design.

* Description of the current options file

* Test the load time of the real file

I received both gratitude and the message that the acceleration failed. Let's figure it out! Do not forget to vote in the poll. We add our results to the pivot table. For suggestions on filling caps write toQMSto userSerVBul . In this topic, you can also write: welcome information about the model of the device, the cellular operator, and, of course, about the result of the done manipulations.
We hide the screenshots under the spoiler: we respect other users who do not want to spend traffic on pictures! (Short lesson "How to clean images under spoiler")

Topic looking forcurator. It is necessary to keep the topic up to date, as well as bring to mind the methods of installation and removal.

radbiartThe instructions imply the inclusion of the "3G only" mode only for the time of speed testing.

[Waterman]

I threw it on the Meizu m2 note. Tele 2. Where I work now, the connection is terrible, in the sense of the Internet. At home, it seems, began to open pages faster. There is enough traffic, Wi-Fi can not be included.

[NeVeR]

Tell me why only 1 sim card displays?
This is for calls, for the Internet in this menu is not.

I noticed that when using the YogaVPN application, the speed increases by 2-3 times, especially when downloading.

No way helped

[Benga1983]

In Samsung a300h there is no such file in the ppp folder, there is only this in-up-vpn

[SerVBul]

Benga1983after applying the script or before the script?

Just because it may not be. Create by hand.

And if the script did not work, then you need to try another installation method.

[Spider88]

There is still this really helps.
