Bootloader unlocking and rooting method for honor 4x : Step by step

There is no need to install superSU after rooting through kingroot. This page documents the development of a LPC bootloader program which makes the following process possible:. Well, that was easy. Last commit 30 Sep by William Reynolds.

Please, contact us at support mbed. Samsung Galaxy S Advance I After rebooting, unplug the phone from computer.

The length of any UU-encoded line should not exceed 61 characters bytes i. I started off the code writing by looking at the section entitled ‘Communicating with the LPC’ in the Prototype to Hardware page. After carrying out bootloafer adjustments, I could take it all the way up to baud, which is the limit described in the LPC handbook.

Lecture 2 – Bootloader – Anton Gerasimov

If trying to replicate the debugging setup, ensure you set up an asynchronous 8-N-1 connection decoding into ASCII unless you’re fluent in binary. Download the adb drivers and follow bootpoader method shown in this video www. Thanks for sharing process to root EMUI3.

This requires the user to convert the binary file into hex and then put it through the flash utility.

Initially, I could only communicate successfully with the mbed by sending commands to it at a baud rate. XDA Labs Labs is an independent app store that gives developers full control over their work. Now type in command window “fastboot reboot” to reboot the phone. The code below is a slightly adapted version of the respective function in the final program at the end of this page.


So armed with my UU-encoding knowledge, I wrote a small program to carry out the conversion and explicitly show the process going on. Step by step by a RedBoot RedBoot was originally for booting eCos, which now is licensed through GPL RedBoot is the only open-source bootloader that supports all architectures It is fairly well documented http: The host should send the check-sum after transmitting 20 UU-encoded lines.

The encoding process is demonstrated by this table, which shows the derivation of the above encoding for “Cat”. Among other things, it discusses the package’s source code layout, the available build options, U-Boot’s command set, and the typical environment variables used in U-Boot. With some chips, you will need to alter the baud rate first, as is not supported by some LPC chips. Guest Quick Reply no urls or BBcode.

By disabling cookies, some features of the site will bootloaser work. We should solve any compiling problems. Add a new configuration option for your board to the top level “Makefile”, using the existing entries as examples. I began by ensuring I could replicate the communication, so I opened up TeraTerm and began typing away. The receiver should compare it with the check-sum of the received bytes.

In order to use the program, compile the program you want to bootload onto another chip and drop it into the mbed’s filesystem flash with the suffix. Boootloader onto the software Tools to build S-Record or U-Boot images, etc.

All I do differently is send the checksum earlier and pad any unrequired bytes in the last 3 to be UUencoded with 0x00s. More and more boards are supported now. Hence, the process could be streamlined by allowing binary files to be directly loaded, which is now possible using this bootloader program.


It turned out that this was as a result of the echo which the chip automatically has switched on when reset. When the data fits in less than 20 UU-encoded lines, then the check-sum should be the sum of the raw bytes sent since the previous checksum was sent.

So we develop a new u-boot based on SMDK I’m now heading back to university, but managed to get very close to hooking up a LPC and a LPC chip to the utility; just trying to iron out an odd bug, which lookw hardware-based, where all the command codes have been successful, but partway through sending the first 1KB block, the chips start sending back the code I sent to them As many people visit here mainly to know Rooting method.

Posting Quick Reply – Please Wait. Note the if statements at the bottom replacing any 0x00s with 0x60s. Then this file can be opened, encoded and sent to the chip before reopening the original file and continuing from where it stopped before.

The description given is too ambiguous and it would be nice to see a graphical explanation. This is something I didn’t discover on the first day and so I kept on getting slight discrepancies between my conversion and that provided by the online UU-Encoder I was using to check my output.
