david 914 Posted November 16, 2019 Share Posted November 16, 2019 Moderator: This is a split from this sailfish thread On 11/16/2019 at 7:41 AM, Craig said: I tried pinging the TWRP developer Chen thanked and will start a new thread (if he doesn't) if he replies with more info. But even the early reports said it could flash, so for installing SFOS it's fine, and for stock backup, we already have a flashall so no worries that way either. Thanks for pinging him. I would like to be able to use TWRP to make nandroid backups of my /data partition (for Android use). Since this is shared in A/B, maybe that works already. I'd also like to be able to use "adb pull" to get the backup off the device, as well as backup the media files (TWRP doesn't include media files in /data backups). I believe "adb pull" only works in recovery mode, with the partition unmounted. I don't know if stock recovery can do that. UPDATE: Thinking about this more, as long as the phone will allow booting off images on a USB connected computer (fastboot boot boot.img), an insecure boot.img could be made and booted off of. This should allow "adb pull/push" to be used to backup/restore /data and /data/media. I haven't used this method before, so I am speaking from theory. The benefit of doing a nandroid backup of /data in recovery mode is that it will pack all the files into one or more tar files. These may transfer easier with adb pull than pulling thousands of individual files. I have had cases where adb pull has hung after some number of files. Running it again, multiple times, allowed it to finish, but it is annoying and increases the time to complete the task. I'll do some testing and create some tutorials on various file transfer methods once I get my phone. 1 Quote Link to post Share on other sites
Sean McCreary 328 Posted November 17, 2019 Share Posted November 17, 2019 The version of TWRP linked from the first post in the Sailfish OS thread works well enough to install Sailfish OS, but YMMV if you want to use it for any other purpose. It cannot decrypt the userdata partition (so you can't use it to make a backup), and you're better off using fastboot to restore the other partitions rather than a nandroid backup made with TWRP. Also, the current bootloader does not support 'fastboot boot boot.img'. ☹️ 1 2 Quote Link to post Share on other sites

I know not every phone supports that, but I really have to think that was just an oversight for fxtec and not done intentionally, since they seem to want to keep things open and available. Maybe @Waxberry can comment on that limitation and whether it will be opened up. Thank you for the information about TWRP. I guess that means there is no way, currently, to do a partition backup with the Pro1 via ADB or Recovery. There might be a way to do it from within Android when rooted, but that's atypical. 1 Quote Link to post Share on other sites
Craig 1,435 Posted November 19, 2019 Share Posted November 19, 2019 (edited) There is a twrp build for Pro1 by Sean MccReary. The info is currently in the SailfishOS thread, but for better visibility I think it deserves it's own thread. TWRP 3.3.1 for Pro1: Download here Edited November 19, 2019 by Craig this was the first post, reordered by mods 3 Quote Link to post Share on other sites
david 914 Posted November 19, 2019 Author Share Posted November 19, 2019 Please move this post to this thread too. It isn't Sailfish related. It is about TWRP and/or alternative ways to backup partitions. Quote Link to post Share on other sites

zurvan2 125 Posted December 11, 2019 Share Posted December 11, 2019 I tried the instructions in the Sailfish thread to install TWRP, but it's failing at the first step to set_active. The set_active command returns different errors every time I run it.

Craig 1,435 Posted December 11, 2019 Share Posted December 11, 2019 If two machines, with two different cables, both do it, sounds like something wrong with the version of fastboot (if you used the same exact version on both?) or your device... Quote Link to post Share on other sites
zurvan2 125 Posted December 11, 2019 Share Posted December 11, 2019 I tried both the official version from https://developer.android.com/studio/releases/platform-tools and "Minimal ADB and Fastboot" from: https://www.thecustomdroid.com/minimal-adb-and-fastboot-tool-for-windows/ The latter had been recommended ... somewhere. Oddly, adb doesn't seem to have any issues, only fastboot. Quote Link to post Share on other sites
zurvan2 125 Posted December 11, 2019 Share Posted December 11, 2019 Great success! I have a linux box in the basement, and it was able to fastboot flash on the first try. Must be some software or driver issue on *both* my windows machines. 😞 1 3 Quote Link to post Share on other sites

david 914 Posted January 24, 2020 Author Share Posted January 24, 2020 Can any version of TWRP read the /data partition yet? Quote Link to post Share on other sites
D1ggs 141 Posted May 6, 2020 Share Posted May 6, 2020 Bumping this thread. Can TWRP be used to flash magisk on the latest version of stock? We're missing the latest boot.img to patch via magisk and unfortunately the lineage OS recovery doesn't play nicely with stock. Quote Link to post Share on other sites

I got close to a functional decrypt before covid hit, but haven't been able to work on it since. I'm focused on getting Lineage finished and official and TWRP should come after that. 6 5 Quote Link to post Share on other sites

Apart from this kind of looking suspicious, it does at least deactivates dm-verity and forced encryption. Since the boot image is patched to deactivate dm-verity and data encryption, I guess you won't be able to install OTAs any more.

What reason is there for wanting TWRP over Lineage recovery other than data decrypt? To do a full nandroid backup. I like to change some settings, icons, play with some apps and a backup will help me to do that, to be on the safety side. TWRP + Tasker are the main reasons why I use Android. Backup and modify/automate 🙂 4 Quote Link to post Share on other sites
TeZtdevice 237 Posted August 10, 2020 Share Posted August 10, 2020 (edited) After 4 software bricks (android accomodation), I stopped using my Pro1. Without TWRP, I can not use the Pro1 as my new dialy driver. Well, I have to wait for it. I hope @tdm or any other dev will find a way to decrypt partition.
