rbr750 刷brs方法和该区方法

  如下：：：

hi_cj@***

这两天已经成功刷了，但是两不了主机。https://www.right.com.cn/FORUM/thread-8305495-1-1.html

我用R6800救砖方法刷入了RBR750出厂固件，网口我试了最接近电源口的这个和wan口最近的一个，不清楚是那个刷进去的。因为也是折腾好几次，最后发现刷进来了。（出产固件就是官网第一个固件最老的）

刷入出厂固件才可以进入http://orbilogin.com/debug.htm 最下面勾选telnet，


然后才有然后。。。。。。。。。。。







R6800救砖刷回官方方法（估计其他型号也可以）我的电脑是win11 64位
我只做补充说明一下，
主要是参考论坛朋友的帖子  R6800救砖刷回官方方法-Padavan-恩山无线论坛 (right.com.cn)
1，那个winpcap软件一直失败(WIN11,64位)，百度换了这个软件npcap，可以直接完美替换。
2，电脑网卡查看D:\> \nmrpflash.exe -L  我的电脑就是net11
3，D:\> \nmrpflash.exe -i net11 -a 192.168.1.1 -f R6800_V1.2.0.92_1.0.1.img   注意前面要加 "\" 才可以。

下面是转贴吧的：


一、固件回滚


1、首先准备手动升级（回滚）的固件
■到http://www.netgear.com，点“SUPPORT”，搜索或选择,找到并确定rbk75x或rbk85x具体型号，点击“Downloads，在Firmware and Software Downloads”目录中，点击“+View Previous Versions”（历史版本）。（如用微软Edge浏览器，可以把所有页面翻译或中文）
■找到你需要的版本，把路由（RBR）、分机（RBS）的固件都下载，分别解压后备用。每个文件解压后有两个文件，.chk就是固件文件了。
（例：为确保Telnet能打开，RBK750可下载最初版本v3.2.10.10）

2、手动升级（回滚）固件
■断开路由器的外网，电脑用网线连接路由器；
■用浏览器（建议用Edge或Chrome）登录路由器：http://orbilogin.com（http：//路由器IP地址）进入路由器管理界面；
■选“高级-->管理-->固件更新”，选“manual update”(手动升级)，然后“浏览”，找到刚才解压得到固件文件（注意区分路由与分身不同），点“上传”，会弹出一个警告“降级到较低版本的固件”，并只显示“否”按钮，没有“是”按钮（也就是不允许回滚）；
■（关键一步）按F12（或鼠标移动到“否”按钮上，右键选择“检查”或“审查元素”）进入网页调试页面，找到“否”旁边的隐藏按钮元素“是”，在“Styles”选项卡下会出现“element.style display：none”，删除“none”，回到固件更新页面，会出现“是”按钮；
■点击“是”，开始更新固件。大约二分钟后路由器会重启，更新完成。再次进入路由器管理界面，高级à管理à固件升级，查看固件版本号，恭喜你，回滚成功。
（备注：根据众多网友的经验，在手动更新（回滚）固件时，路由器和分身应分别操作，最好先升级（回滚）分身，再升级（回滚）路由器）


二、解锁路油器地区

1、准备工作
■ 把路由器和分身恢复出厂设置（这可以解决很多小问题）
■完成基本配置，不要连接到互联网

2、开启telnet功能
■登录路由器管理页面：http://orbilogin.com/debug.htm（http：//你的路由器地址/debug.htm）,进入路由器管理界面。在最下面telnet选项上面打勾：

3、登录路由器debug页面
■ 按下win+r
■输入:telnet 你的路由器地址
会提示输入用户名，输入你的路由器用户名admin
提示输入密码，输入你的路由器登录密码（不显示）
■进入欢迎界面

■开始配置：
输入：cd bin，回车；
输入：burnsku 0x0002，回车（选全区）
输入：reboot，回车（重启路由）
■重新登录路由，高级-->无线设置，自由地选取地区。今后再升级固件，无线地区依然能够自由选择。
(如果你的电脑没有安装telnet服务，请打开：设置à应用à程序和功能à启用或关闭windows功能，然后找到“telnet客户端”，勾选，确定。）


三、阻止路由器自动升级

（注意：这一步不是必须的。如果你确认某一个版本的固件是稳定工作的，想保留在这个版本并阻止路由器自动升级，则可以进行）
1、Telnet 连接到路由器，并运行以下命令：
nvram setauto_upgrade_enable=0
nvram setver_check_https_svr1=http.fw.updates1.aaa.com
nvram setver_check_ftp_svr1=updates1.aaa.com
nvram setver_check_ftp_svr2=updates1.aaa.com
nvram setver_check_ftp_svr3=updates1.aaa.com
nvram setlang_check_ftp_svr=updates1.aaa.com
nvram setinstall_fw_upgrade_latest=0
nvram setver_check_enable=0
nvram setver_check_ftp_password=aaa@aaa
nvram set control_cloud_backend_fw_url=https://http.fw.updates1.aaa.com
nvram setpromotion_server=updates1.aaa.com
nvram commit

2、转到管理页面“高级-->安全-->阻止站点”(Advanced -->Security--> Block Sites)
■关键字阻止设置为“始终”(Always)
■添加以下关键字：
http.fw.updates1.netgear.com
updates1.netgear.com
■单击“应用”
■重启路由器
这样就阻止了路由器停留在某个版本不再自动升级。今后有升级需要手动升级即可。

刷固件没必要用救砖工具硬刷，正常可以通过路由器自己升级的方式。当然用windows自带的 Tftp代替nmrpflash.exe。也是可以直接刷固件的。
tftp -i 192.168.1.1 put r7500V2.img

]RBR850刷RBS850方法：转国外 原网站如下：转换 RBR 850 （路由器） 到 RBS 850 （卫星） ： r/家庭网络 (reddit.com)
Converting RBR 850 (Router) to RBS 850 (Satellite)

My first Reddit post with hopefully helping others with similar situtation!

Before some months I decided to switch to Netgears Orbi RBK850 System. Until then I used a Linksys AX2200 System. But this was no option any more after moving in to a flat with 1 GBit/s ISP avialiabilty.

Having headache about the price I bought a used, more precice, two used packages with 2 routers (RBR_850) and in sum 5 satellites (RBS_850).

Starting with one router and successively extending my range and performance with up to 5 satellites. I needed a 6th one for the garage and was sure I can use RBR 850 as satellite. No chance. Only option was to use it as AP with same Wifi SSID and PW as the "main Wifi". But that was not the way I wanted to end up with.

After hours of searching, if there is something like a hack to enable satellite mode on a orbi 850 router, by mistake I found a post, how it is possible to convert a Netgear RBR 50 (NOT 850) to RBS 50.

Here the Link to RBR 50 conversion:

[color=var(--color-primary-background-hover)]https://www.reddit.com/r/HomeNetworking/comments/e53qp6/convert_orbi_rbr50_router_to_orbi_rbs50_satellite/?utm_source=share&utm_medium=web2x&context=3

I thought it would be more or less the same procedure... close, but far from it...

First: On RBR 850 there is no old Firmware, for a downgrade where telnet, which is needed for the process, could be enabled. But a smart guy created a phyton script to solve this problem.

So, here a step by step with some troubleshoot on the final steps: (This should work on every OS)

Caution! This could brick your device! Maybe no recovery is possible! Be aware you could damage your device. If unsure, do not use this guide. It is just about my personal experience, fortunately with success. Go on at your own risk!

• Download the latest firmware from Netgears Homepage for the RBS 850: [color=var(--color-primary-background-hover)]here (Netgear) and unzip it.
• Download telnet_enable python script: [color=var(--color-primary-background-hover)]here (GitHub)
• If not done yet, install python 3 (>= 3.8)
• Power on and connect your RBR 850 with ethernet cable to your Computer (Mac/Linux/Windows).
• Go to [color=var(--color-primary-background-hover)]http://192.168.1.1 and go through initial config as far as needed (setting password for admin is mandatory), skipping as much as you can, because in few minutes we flash a new firmware on it and everything will be deleted (except the PW ).
• Note or copy the MAC address of this router.
• Enable telnet Service on RBR 850 with the python script above, in dependence of your OS, with something like:
  
  
  • python3 telnet-enable2.py 192.168.1.1 [MAC ADDRESS e.g 'A0:40:A0:69:B6:30'] admin 'yourpassword'
    
• If not done yet enable telnet in windows10/11 [color=var(--color-primary-background-hover)]telnet (Windows) or install via homebrew on macOs [color=var(--color-primary-background-hover)]telnet (macOS) (maybe you need first to run brew update and brew upgrade) . No neccesisity to explain for Linux ;)
• Then telnet to your router:
  
  
  • telnet [color=var(--color-primary-background-hover)]192.168.1.1
  • Log in with admin and your password (from step 5) and execute following commands:
    
    
    • cd /sbin
    • board_data -r board_id - should show: 'U12H404T00_NETGEAR'
    • board_data -r hw_version - should show: 'RBR850'
      
  • Now lets change the board ID and HW Version, type:
    
    
    • board_data -w board_id U12H403T00_NETGEAR (from ...H404... to ...H403...)
    • board_data -w hw_version RBS850 (from RBR to RBS)
    • board_data -r board_id - should now show: 'U12H403T00_NETGEAR'
    • board_data -r hw_version - should now show: 'RBS850'
      
  • reboot the router with reboot or unplug and plug in power cord.
    
• The router is now ready to accept the Satellite Firmware (from Step 1).
• In a browser go to [color=var(--color-primary-background-hover)]192.168.1.1, log in with admin and your password (from step 5).
• Go to Advanced > Administration > Firmware Update > Manual Update
• Click on Browse and select the satellite firmware from Step 1 (e.g. RBS850-V4.6.14.3-signed.chk)
• Click on Upload
• Be patient.
• Be patient..
• Be patient...
• When the Router comes up connect it via ethernet cable (NOT the WAN port!!!) to an other satellite or to your origin orbi router.
• After a few minutes you see the new RBS 850 as orbi device in the list of connected devices, but not syncing to the existing mesh.
• You can log in to it by typing the assigned IP to your browser and using admin and your password from Step 5. You now see the satellite firmware interface and not the router interface.
• OK. Lets sync the new born satellite to our existing mesh. This step is weird. Without knowing why. after the 4th hardreset I succeeded.
• Hardreset:
• Unplug new Orbi, press and hold reset button and plug in power cord.
• Keep holding reset button until white light is pulsing.
• Sync to Mesh:
• log in to your origin orbi router and go to 'add orbi satellite' > next > sync
• Cross fingers
• be patient
• be patient
• be patient
• Check if new satellite is part of mesh...
• Happy meshing!
  

Some troubleshoot:

If satellite is not syncing:

• Repeat step 21 with all substeps and be patient.
• If this not helps, connect the ethernet cable to the ethernet port next to power plug and repeat from step 21.
• If this does not lead to sync, for the hardreset procedure additionally press and hold sync button until the white light is pulsing. Repeat from step 21.
• No luck? Do not unplug orbi and press 7 seconds reset button. Then repeat step 21
• Try with 30 seconds without unpluging. Then of course step 21
• Try wih 30 seconds after unplug and plug in again.
• Don´t give up. Try again and again. As far as you new RBS comes up and gets an IP via wired connection from origin router or other satellite, its just a syncing issue. Maybe something with the timing or so. But it is not bricked as long as you can log in.
• If it does not come up try netgears recovery mode with flashing original Firmware via tfpt: [color=var(--color-primary-background-hover)]tftp (NETGEAR) and start again with Step 4.
  

I hope this helps you to expand your orbi experience!



[color=var(--color-neutral-content-strong)]将 RBR 850（路由器）转换为 RBS 850（卫星）RBR750转换应该也类似的
[color=var(--color-neutral-content)][size=0.875]

我的第一篇 Reddit 帖子，希望能帮助其他人有类似的坐姿！

几个月前，我决定改用Netgears Orbi RBK850系统。在此之前，我使用的是 Linksys AX2200 系统。但是，在搬进具有1 GBit/s ISP飞行能力的公寓后，这不再是选择。

由于对价格感到头疼，我买了一个二手的、更珍贵的、两个二手的软件包，带有 2 个路由器 （RBR_850），总共 5 个卫星 （RBS_850）。

从一个路由器开始，然后连续扩展我的范围和性能，最多 5 颗卫星。我需要第六个车库，并且确定我可以将RBR 6用作卫星。没有机会。唯一的选择是将其用作AP，具有与“主Wifi”相同的Wifi SSID和PW。但这不是我想要的结局。

经过数小时的搜索，如果有黑客在 orbi 850 路由器上启用卫星模式，我错误地发现了一篇文章，如何将 Netgear RBR 50（不是 850）转换为 RBS 50。

这里是RBR 50转换的链接：

[color=var(--color-primary-background-hover)]https://www.reddit.com/r/HomeNetworking/comments/e53qp6/convert_orbi_rbr50_router_to_orbi_rbs50_satellite/?utm_source=share&utm_medium=web2x&context=3

我以为这或多或少是相同的程序......近在咫尺，但远非如此...

首先：在RBR 850上没有旧固件，对于降级，可以启用该过程所需的telnet。但是一个聪明人创建了一个phyton脚本来解决这个问题。

因此，这里是一步一步的步骤，其中包含最后步骤的一些故障排除：（这应该适用于每个操作系统）

谨慎！这可能会使您的设备变砖！也许不可能恢复！请注意，您可能会损坏设备。如果不确定，请不要使用本指南。这只是关于我的个人经历，幸运的是成功了。继续自担风险！

• 从Netgears主页下载RBS 850的最新固件：[color=var(--color-primary-background-hover)]这里（Netgear）并解压缩。
• 下载telnet_enable python脚本：这里（[color=var(--color-primary-background-hover)]GitHub）
• 如果尚未完成，请安装 python 3 （>= 3.8）
• 打开电源并使用以太网电缆将RBR 850连接到计算机（Mac / Linux / Windows）。
• 转到 [color=var(--color-primary-background-hover)]http://192.168.1.1 并根据需要进行初始配置（必须为管理员设置密码），尽可能多地跳过，因为几分钟后我们会在其上刷新一个新固件，所有内容都将被删除（PW 除外）。
• 记下或复制此路由器的 MAC 地址。
• 使用上面的 python 脚本在 RBR 850 上启用 telnet 服务，具体取决于您的操作系统，如下所示：
  
  
  • python3 telnet-enable2.py 192.168.1.1 [MAC ADDRESS e.g 'A0:40:A0:69:B6:30'] admin 'yourpassword'
    
• 如果尚未完成，请在 windows10/11 [color=var(--color-primary-background-hover)]telnet （Windows） 中启用 telnet，或通过 macOs [color=var(--color-primary-background-hover)]telnet （macOS） 上的自制软件安装（也许您需要先运行和 ）。对于 Linux ;)没有必要解释brew updatebrew upgrade
• 然后远程登录到您的路由器：
  
  
  • telnet [color=var(--color-primary-background-hover)]192.168.1.1
  • 使用 和 您的（从步骤 5 开始）登录并执行以下命令：adminpassword
    
    
    • cd /sbin
    • board_data -r board_id- 应显示：“U12H404T00_NETGEAR”
    • board_data -r hw_version- 应显示：“RBR850”
      
  • 现在让我们更改主板 ID 和硬件版本，键入：
    
    
    • board_data -w board_id U12H403T00_NETGEAR（从...H404...自。。。H403...
    • board_data -w hw_version RBS850（从 RBR 到RB S)
    • board_data -r board_id- 现在应该显示：“U12H403T00_NETGEAR”
    • board_data -r hw_version- 现在应该显示：“RBS850”
      
  • 使用或拔下并插入电源线重新启动路由器。reboot
    
• 路由器现在已准备好接受卫星固件（从步骤 1 开始）。
• 在浏览器中转到 [color=var(--color-primary-background-hover)]192.168.1.1，使用 admin 和密码登录（从步骤 5 开始）。
• 转至高级>管理>固件更新>手动更新
• 单击浏览并选择步骤 1 中的卫星固件（例如 RBS850-V4.6.14.3-signed.chk）
• 点击上传
• 要有耐心。
• 要有耐心。
• 要有耐心...
• 当路由器启动时，通过以太网电缆（不是WAN端口!!）将其连接到其他卫星或您的源orbi路由器。
• 几分钟后，您会在连接的设备列表中看到新的 RBS 850 作为 orbi 设备，但未同步到现有网格。
• 您可以通过在浏览器中键入分配的 IP 并使用步骤 5 中的管理员和密码来登录它。您现在看到的是卫星固件接口，而不是路由器接口。
• 好的。让我们将新生卫星同步到我们现有的网格中。这一步很奇怪。不知道为什么。在第 4 次硬重置后，我成功了。
• 硬重置：
• 拔下新奥秘的插头，按住重置按钮并插入电源线。
• 继续按住重置按钮，直到白灯闪烁。
• 同步到网格：
• 登录到您的原始奥秘路由器，然后转到“添加奥秘卫星”>下一个>同步
• 交叉手指
• 要有耐心
• 要有耐心
• 要有耐心
• 检查新卫星是否是网格的一部分...
• 祝您啮合愉快！
  
  

一些故障排除：

如果卫星未同步：

• 对所有子步骤重复步骤 21 并耐心等待。
• 如果这没有帮助，请将以太网电缆连接到电源插头旁边的以太网端口，然后重复步骤 21。
• 如果这不会导致同步，对于硬重置过程，请另外按住同步按钮，直到白光闪烁。从步骤 21 重复。
• 没有运气？请勿拔下奥秘电源并按 7 秒重置按钮。然后重复步骤 21
• 尝试 30 秒而不拔下插头。然后当然是步骤21
• 拔下插头后 30 秒尝试，然后重新插入。
• 不要放弃。一次又一次地尝试。就您而言，新的RBS出现并通过来自源路由器或其他卫星的有线连接获取IP，这只是一个同步问题。也许是时机之类的东西。但只要你能登录，它就不是砖砌的。
• 如果没有出现，请尝试通过tfpt：[color=var(--color-primary-background-hover)]tftp（NETGEAR）刷新原始固件的netgears恢复模式，然后从步骤4重新开始。
  
  

我希望这能帮助你扩展你的奥秘体验！

How do I upload firmware to my NETGEAR router using a TFTP client on Microsoft Windows? - NETGEAR Support

How do I upload firmware to my NETGEAR router using a TFTP client on Microsoft Windows?
Was this article helpful?   Yes     No

If your NETGEAR router is unusable (bricked) or experiences other problems during or after a firmware update, you can use a TFTP client on your computer to upload firmware to your router remotely.

These instructions are specific to Microsoft Windows computers. For Apple macOS computers, see How do I upload firmware to my NETGEAR router using TFTP on Apple macOS?

You might want to try to upload firmware to your router via TFTP if you are experiencing any of the following symptoms:

Router is unusable (bricked) after a firmware update
Router doesn’t boot properly
Power LED is blinking or solid amber
Firmware update attempts fail
Unable to access router web interface
Router does not assign DHCP addresses to clients
Important: Uploading firmware to your router via TFTP requires more networking and computer knowledge than updating from the router web interface. Read through all of the following instructions before proceeding. If you do not understand any step of the process, contact NETGEAR technical support and do not proceed.

To upload firmware to your NETGEAR router using a TFTP client on Microsoft Windows:

Download and install Tftpd64 from the Tftpd64 website.
Download the ZIP file containing your router’s firmware update file from the NETGEAR Download Center.
Extract the ZIP file to your desktop. The firmware file format is either .img or .chk.
Using an Ethernet cable, connect your computer directly to your router.
Set your computer to use a static IP address:
Click the Windows icon in the taskbar or press the Windows key on your keyboard. The Start menu displays.
Type network connections.
Click View network connections or press the Enter key.
Right-click Ethernet and select Properties.
Double-click Internet Protocol Version 4 (TCP/IPv4).
Select Use the following IP address and enter the following values:
IP address: 192.168.1.10
Subnet mask: 255.255.255.0
Default gateway: 192.168.1.1
Click OK to save the configuration.
Configure Tftpd64 to connect to your router:
Launch Tftpd64.
In the Server interfaces field, select your computer’s LAN adapter.
In the Host field, enter 192.168.1.1 (the default router IP address).
In the Port field, enter 69 (the default port number for TFTP).
Click the … button next to the Local File field.
Browse to the firmware file that you downloaded and select it.
Caution: Do not click Put until you are instructed to do so!
Unplug all other Ethernet connections from your router, leaving only your computer connected.
Turn your router off for 10 seconds.
Turn your router back on.
Wait for the Power LED to light orange and start flashing.
When the Power LED is flashing, click Put in Tftpd64 to initiate the firmware upload. The upload might take a few minutes.
If the firmware upload is successful, a dialog box appears to confirm the blocks transferred, with a 0 block retransmitted message and a MD5 checksum. If the firmware upload fails, repeat steps 8-11.
Wait about 4 minutes for the router to finish storing the firmware into its flash memory. When finished, the Power LED turns solid white and the wireless LEDs light up.
Return your Ethernet network connection settings in Windows to the previous settings.
If you don't want to download a TFTP client, you can also upload firmware using the Microsoft Windows Command Prompt. For more information, see How do I upload firmware to my NETGEAR router using TFTP using the Microsoft Windows Command Prompt?
