Thanks for getting back to me @aibd!
Yes, I was quite surprised to see that so many people are reporting boot loops on the GS290. Being an officially supported device I expected a very smooth flashing procedure.
I’ve read your first link (Gigaset - GS290 - gs290 - Documentation Suggestions - #69 by mc21), but am not sure how to this relates to my case. First of all, let me give you some additional information:
- I’m on a Linux system
- I downloaded the latest platform-tools (fastboot version 32.0.0-8006631)
Your linked thread mentions SPFlashtool. I haven’t tried yet, because I read threads, that the the GS290 was completely bricked after trying to flash something with SPFlashtool. So I’m a bit afraid of that happening to mine as well.
I’ve been using TWPR with LineageOS on some Samsung phones quite successfully. Therefore, I was hoping for an TWPR image for the GS290 as well. But every download link for GS290 TWPR I found so far was broken.
