E5573s-856 design 

Software Information
The software version information of device E5573s-856 China mainland is as follows:
Firmware Version: 21.329.63.01.1394
WEBUI Version: 17.100.20.01.1394
the firmware version is new, and will prompt a “fail to switch to download mode” error, so downgrade to a lower universal version is a little more difficult than old versions. The normal update will receive a “ switch mode error”, or “DATALOCK CODE” required. There are some way to disassemble it and update, it is possible, but it is more time-consuming, if quantity of device are to be proceeded, you will suffer the hardware disassemble.
Here, we have tested a modified firmware to update directly without the command knowledge, and got success.


 

After the modification, the 

modified version of the program is successfully written. It is 
 

After the downgrade of the modified version, its real version comes to be 21.200.13.00.00. The WEBUI version remains the same as we have not included webui into our modification. With the modified firmware, we can use some background services such as ftp as below.

After firmware downgrade, It is relatively easy to flash a multi-lingual WEBUI:

Huawei network card/router unlocking limit is out of the limit

How to reset SIMLOCK attempts

X



The number of SIMLOCK attempts is 0. In order to save money, we sometimes risk the failure to try a variety of free unlock codes or counting tools, sometimes successful. But most of the time it fails, and therefore consumes 10 attempts. We also occasionally unfortunately see that the device's SIMLOCK attempts are 0 times, as shown above. 
In the case of the above situation, don't worry too much. This article will explain some solutions. Please insert a SIM other than the custom carrier (the above figure will appear in the unlock box), and then gradually try the following methods. 
Method - 1 (for the unlock code or router of Huawei algorithm V1 and V2) 
1. The unlock code calculated by IMEI; 2. The md5 hash value (32 characters) calculated according to the unlock code; 3. Disconnect the Internet and close the router. webUI/Dashboard, etc.; 4. Open the task manager, if there is "HWDeviceService.exe", please close the process; then go to the Dc-unlocker client software and click the amplifier icon to search for the device and enter the following command 
at^cardunlock=”md5 Hash" (with quotes in English) For example: your unlock code is 96387456, md5 hash value is "3e9e45f2401dc32e3e4a7ce8495cf1e4" 
then the command in DC-unlocker is: 
at^cardunlock=”3e9e45f2401dc32e3e4a7ce8495cf1e4” 
If the command successfully resets the counter, You can see the results in the following figure: 
Note: If dc-unlocker cannot find the device, please install the Huawei driver and then connect the device to the computer through the USB port. 
Method-2 (for Huawei algorithm 3 – V201 and algorithm 4 devices) 
If the above method is invalid, you can try the following command in the dc-unlocker software.
At^datalock=”unlock code” with English quotation marks 
at^maxlcktms=10 Without quotes 
If the reset is successful, 10 attempts will be displayed in the DC-unlocker software, as shown below. 


Attempts Display Method 3 (for the device attempts Huawei default 0) If 0 is the default device number of attempts, by way of the brush into the common firmware restore attempts. 1. Download the general firmware; 2. Brush the general firmware, you may be prompted to enter the Flash Code, which can be generated according to the IMEI number; if successful, you can see the remaining 10 times in the DC-unlocker test result; -4 (Resolve most of Huawei's device problems) If the above methods are invalid, don't give up, the last method is to use DC-Unlocker to directly unlock (the tool directly unlocks the account that needs to have recharge points, or dongle) 1. If you Encountered an error code like "Error 42 or 40", then your device has been permanently locked, then do not consider the number of restore attempts, you can only use the tool to directly unlock; 2. Buy a number of accounts from a versatile treasure After purchase, you will get the username and password (note that each device needs to be unlocked differently, you can check the software official website www.dc-unlocker.com to see how many points you need, and then buy enough points) 3. Use the user after purchase Login with the name and password, then you can unlock the device directly.

Select E5577s_Update_WEBUI_17.100.09.02.03_MRE5_Universal. After the brush is completed, enter the background. Perfect multi-language: 


Shining 11 languages Off-topic: 
1) After testing, I want to change IMEI in the process. No problem, if there is a special need, you can get it through the brush machine; 
2) This model is safer, generally not bad. Even if the problem is solved, there is no signal, the computer can't detect it, and the device can be solved as long as the device has a light. Write a follow-up to save the brick ......

Huawei E5186s-22a does not display the IMEI search method

2016-11-01 02:04 read:420

As a Huawei 4G+ product, the E5182 is a relatively new device. I saw some equipment with my own eyes. IMEI is only on the label of the box. There is no label on the back of the device. The product page of the device is not displayed. The example is as follows:

X

The IMEI 


device label on the outer box does not have the IMEI 

product information page or the IMEI. It can be seen that the IMEI of the device is only on the box, so how do you find the IMEI number in case you take over such an empty device? What? Remove the backboard? USB connection? What is it? 

After testing, you can try the following methods: 
1. 


View the IMEI under the software tool 
2. Open telnet, use the ati command to display the 


IMEI above the self-tested viewing method, I believe there are more ways to Do it, not in one case, for reference only.

Huawei E8372h-153 O! Unlock brush multi-language

2016-11-02 02:57 reading:3,657

E8372h-153 O! logo The equipment obtained this time is the customized version of O! logo E8372h-153, the card accesses the background 192.168.8.1, see the input SIMLOCK prompt, the default 10 attempts; 

ignore the prompt, enter the device information page, see the device information as follows: 
! O interface customization, magenta color, built-in three languages; 
firmware version 21.210.03.00.1336; 
Web version of the UI: 17.100.09.08.1336; 

customizable interface and version information steps: 
1. switch device mode to RAS mode (MODEM mode) 
default is NDIS mode, the display is a local network connection, only a browser to access the background, computer device Manager does not show the serial COM, unable to input various commands; 
switch After the modem mode is installed, the computer task manager will display two Huawei COM ports. When the machine is flashed, the software will find the COM port and the port brushing opportunity will not be found. The 
switching mode can be done with tool software or script. 
2. Switch factory mode to 
the RAS mode, the driver installation is complete, the COM port, the majority of the device has to run the program to complete the brush, no need to switch to the factory mode 
But relatively few new version, the flashing process after reboot prompted to find the port, RUU Caton does not move, this situation would need to switch to the factory model before running Brush software; 
so this step is optional Sometimes you don't need this step. 
Switch factory mode can only be executed under the command; 
3. Run the downgrade firmware flash program 21.110.99.04.00 for firmware downgrade
The reason is the high NDIS downgrade the firmware version of the reading device encryption hash command can not run, can only read hash value after the downgrade; 
downgrades need to enter the password Flash Cod Brush e, according to the imei number calculation input can successfully complete the downgrade; 
4. Under the degraded firmware, DC and other terminal software can obtain the device hash value; 
5. Calculate the unlock code cardlock code according to the read hash value (solution SIMLOCK) Use), and OEM code datalock (brush multi-language) 
Directly enter the unlock code in the degraded mode is not responding, you must brush back to NDIS router mode before you can enter; 
6. Run 21.180.07.00.00 universal version of NDIS routing firmware Successfully brush back the router function 
device to insert the SIM card of the non-customized carrier. After booting, the browser opens 192.168.8.1 to access the background of the router. You can see the SIMLOCK input box and input the SIMLOCK unlock code calculated in step 5. The device is unlocked; 
open the device information page, you can see that the firmware version has changed, but the interface is still O! Customizable, as shown below: 


interface unlock 
7. Run the Web UI update software 17.100.12.00.03, brush into a multi-language interface 
if the program can not find a port, Please mode switching device to the modem software or script; 
upgrade process requires 5 steps datalock code, not the Flash code step 3 brush brush codes used by the firmware. 
Enter the correct code datalock, WebUI after the update is complete, multi-language interface on a perfect show, as follows: 

Built-in 11 languages common interface to this unlock brush multiple languages to complete the technical details can be added to the micro-letter

Huawei E5172s-927 STC Saudi version brush machine unlock

2016-11-05 03:51 reading:568

X



Insert the SIM card status display lock in the upper right corner of the card outside the STC. The Saudi version of the E5172s-927 STC is similar to the China Mobile custom B310As-852, that is, the device does not have a SIMLOCK lock, so there is no need to enter the number! Various restrictions such as the SIM card are in the firmware, so as long as you can successfully brush the machine, you can smoothly remove the restrictions. 
Brush firmware, easy and easy to say, that is difficult is difficult. For example, under Tu Shate this firmware version: 
V200R001C1206SP060 


a locked version of the firmware: V200R001C1206SP060 
This is a custom firmware, firmware may want to brush into common not so easy, because the firmware can not pass the check, regardless of background web upload, or using Brush tool It is difficult to succeed. 
High level of hardware business, will write and write the way the library, but to disassemble, connected write, relatively time-consuming, inefficient, although do not need to unlock points, the software costs and other inputs, but labor costs should not be overlooked. 
If there are 5000 devices, rely on this hardware solution, then you at least 10 days in black and white two shifts uninterrupted operation can complete. 
Here we talk about the practice of this inefficiency, our idea is: 
modifying firmware verification through the brush, then the brush tool with a multicast LAN, if the LAN switch 48 * three, then there are 144 ports, Remove 4 ports for configuration, 140 ports for connecting E5172 for brushing, then one batch can brush 140 units, and 5,000 units for 36 times. Suppose a batch of brushes for 20 minutes (although the brush itself may only be 5 minutes, but the batch takes into account the delay time of various processes such as equipment unpacking, plugging, connection, etc.), then it takes 6.7 hours, saving time and effort! Of course, the conditions allow you to stack more switches, which saves time. We only use 3 sets as an example. 
Of course , we need to prepare three 48-port switches, 150 plug-in board interfaces, and 150 network cables for batch operation. Rent it, not necessarily. 

Whether or multicast a single brush, brush the firmware can not do without, which is the foundation! 
1. rewritten through the brush firmware 
figured brush, will inevitably need common firmware, but I did not find E5172s-927 firmware through the brush, he found a temporary firmware V200R001C00SP060 E5172s-22 be modified for web upgrade by checking: 


local Select to rewrite the firmware for web upload update After the 
upgrade is completed, the interface is as shown below. Huawei's universal multi-language interface, SIM card no longer displays the lock flag, indicating that the firmware limit has been canceled. 


Brush the general firmware rewritten by E5172s-22 universal firmware. 
Since there is no actual measurement of the firmware performance, I am not sure whether there will be frequency problems, heat problems, etc. in different versions of the cross-brush, so if the general-purpose firmware is not working well, you can simply brush a lock-free version of the E5172s-927 firmware. There is usually no more compatibility issues with the use. 
Other brush into the firmware version in general, is generally not limited, can choose the version, it is relatively simple. 
2. Brush the E5172s-927 firmware lock-free version of the 
assumption that the general-purpose firmware does not work well, you can not find a lock of the same type of brush into the firmware can be used to select the version: E5172s-927_V200R001C115SP100 (no lock plate, I do not have this sub-model universal version)


Brushing another STC lock-free firmware After the brush is finished, the SIM is still unlocked, and a new profile can be used to access the Internet. 
Note: From the generic version to be easily customized version of Brush, from customized version of the generic version of the brush back is difficult and requires a firmware rewrite 
other firmware version I rewrote are: 
E5172As-22: V200R001C418SP101 / V200R001C418SP050 
V200R001C1225SP100 
E5172S- 927: V200R001C1206SP060 
There are also B593s-850/s-22/s-601/s-931/s-12/s-42/s-82, etc. Various models of various customized versions

Vodafone B3000, is actually a customized version of Huawei B593s-22, Vodafone logo, red theme color, customized packaging:

X

B3000 (a customized version of B593s-22) package 

bride red interface, and more festive from personal preference to see, really do not like the customizable interface, feeling ugly, or fresh Huawei standard interface ah! And no Chinese, I am awkward in my big day with equipment that does not display Chinese! 
 

Indicates the model and firmware version of the custom models show B3000, firmware version V200R001B236D30SP10C11, I think it knocked off customized model information and interface, but to restore. 
However, this custom firmware can not be so well brushed, ordinary general firmware can not be brushed in, you need to edit the firmware before you can brush in; 
modify the local upload through the web background, the brush is gorgeous multi-language, the following picture appreciation: 
 

14 languages are interested please add the exchange of micro letter
