Hello ! I got my Creta AR-750 today. It is my first GL Inet Router and I am not very technical, so forgive me if the solution is obvious… I am just exploring this new world… I was able to configure some basics things like the SSID, then update the firmware, then I enable the file sharing and it did install something for enabling file sharing. (but I didn’t see where to share my files and where to access my files then, but it is an other subject, I will search). Then I went to install Luci, because everybody is talking about Luci so I want to see what it is and how it works. And here is the issue : > Status : intalled failed > Stderr : No enough flash space. But… what !? It’s brand new, I installed almost nothing, I played with it 5 minutes, and there is no enough space ? I put a 32Go micro-SD card… but I understand “flash space” is not my micro-SD card. So… how can I free the flash space ? What can I do ? Thanks !! ---

Thanks ! I see lots of posts mentionning the issue of free space but I didn’t really see the solution, or maybe it’s just I don’t understand it. In the Plug-ins list, I can see 271 installed. Can I desintall some of them to free space ? Or is there some config to do, to be able to use the micro-SD card space ? Or I am better to reset to factory settings and NOT upgrade the firmware ? (But it seems strange to work with an old firmware on a brand new device… Usually the first thing you do when you set up new stuff is to update the firmware… ) Is there security issues of using an old firmware ? Thanks ! ---

One of the solutions that seems to work is that found by David here: > [@AR750: Firmware 3.201beta2 - no free space at all to do anything](https://forum.gl-inet.com/t/ar750-firmware-3-201beta2-no-free-space-at-all-to-do-anything/14602/5): > > Thank you all very much for these explanations. I am not a technician at OpenWRT, so I learn slowly. I finally got the AR750 to work fine. I discovered the new Mountpoints feature in Luci. To solve my problem, I factory reset my AR750 so I have about 150 kb free. I had an old 512MB USB stick, I formatted ext4, and I use the new Luci feature in firmware 3.201 Mountpoints to do the overlay mount point … reboot … now I have 477mb extra and then I restore my settings so I can make changes and inst… and here: > [@2MB free on AR150 after installing 3.201](https://forum.gl-inet.com/t/2mb-free-on-ar150-after-installing-3-201/15859/7): > > Hello! You have an USB slot. You can put an old USB flash memory there (a little and tiny model not big) and make extroot /overlay to add this USB memory extra space to the router.

I will try. I reset to factory. Then I will try. It may be possible with the micro SD instead of USB stick ? It will be better if yes, I will try… ---

I tried, but without success. Adding the SD card as a mount point : ![Screenshot_20210610-115621](https://forum-static.gl-inet.com/original/2X/9/9e2353e801331cf6f5b554a4fde19dc993e186d1.png) ! But after the reboot, still no memory added : ![Screenshot_20210610-120408](https://forum-static.gl-inet.com/original/2X/4/44a37c594e37782977a59653fbca9a8605f26807.jpeg) ---

Finally … After two other reset to factory… after doing partitions and formatting SD card in EXT4 and NTFS … I think I succeed !!! ![image](https://forum-static.gl-inet.com/original/2X/4/42cc24b950661b123729f11dee8b426ce03a7e1b.png) ![image](https://forum-static.gl-inet.com/original/2X/d/d28012db28672822f6df29013f9a6a26bafd11c4.png) 🥳 ---

oh no … I doesn’t work ! On the Administration panel, if I go to file sharing to install the pluging for file sharing, I still see this : ![image](https://forum-static.gl-inet.com/original/2X/8/8967023ed9b32b63dc0ea00a3a4407108f7b30aa.png) I understand nothing… Why I can see 4.2GB free on Luci but still only 2% free on the admin panel ? 🤨 It’s strange. Is there an issue calculating percentage ? But it’s OK finally more than 3000MB. It’s just the percentage that is bugued. ---

Finally everything is OK. It is juste the percentage % that’s not calculated correctly, seems like a bug. But I have all the free space I wanted to install everything I need. For those with same issue, this is the solution : 1- Install [AOMEI Partition Assistant Standard](https://www.diskpart.com/fr/free-partition-manager.html). on your computer 2- You don’t want to use all the SD card for the system, so do 2 partitions : one named System in EXT4 (example 4Go, I think it is sufficient), one named Data in NTFS (all the remaining space). System will be /dev/sda1 Data will be /dev/sda2 3- In Luci, System\>Mount Points, add the mount point for the System partition (/dev/sda1) with the type Overlay ![image](https://forum-static.gl-inet.com/original/2X/9/91832320b562c6ab65a2041984bfdadfce5ead2a.png) Final result : \*\* ![image](https://forum-static.gl-inet.com/original/2X/e/e66e76561df630ef13313fe9a6618b7ffac8e283.png) \*\* It worked for me 🙂 Good luck ---

I think Luci is calculating it as a percent of the total nonvolatile ram, and the admin panel is calculating it as percentage of the non-rom part. Or maybe vice versa. ---

Much thanks for this post! It took a few option toggles and restarts but made my GL-750 usable again on FW version 4.3.18. ---
