    Hi, I have a Lumia 830. the phone was dead for many years and I wish to fix that. I downloaded ffu and ede files and also the donor as you mentioned. I can reach to "flash" state (two crosses on the phone screen), but when I try to unlock the bootloader, or even flash the phone, that stopped in some same percentages (6% o r7%) and don't move after that. is this a hard issue or that could be fixed?

    Hi! This could be either software / hardware flaw, can't really pinpoint which is the problem. In exactly what step the flashing stops? "Scanning for flashing profile" or just in regular flashing? Best you can do is try to flash the device using the advices given in our guide to the letter:kzread.info/dash/bejne/l3V-qtmMZ8i5XZs.htmlsi=76-5tpBFJgmp1tYf If this doesn't work, try in a different PC and make sure to use USB 2.0 ports & a different data cable. If the process always getting stuck in the same percentage in each attempt always, then that can be a hardware defect.

    Hi! This guide is for devices with bootloader spec-b, the 820 is a spec-a device so this guide isn't applicable. I haven't made a SPEC-A video guide yet (hopefully soon when I resurrect a SPEC-A device) so you might need to follow the Documented SPEC-A guide in W.U.T or some other guide from a trusted source. That said, some info in this guide also applies to SPEC-A unlocking as well but the used files & the process is a little bit different.

    @@w10mgroup Thank God, I have not yet attempted it on my Lumia 820, I was about to but I thought I'd write to you first. I tried to find other sources but they were a bit confusing. Your way of explaining step by step is more clear. I will wait until you make one for Spec-A device so I can make it fully usable again in 2024. I have followed your guide and updated it to GDR2 WP8.1 Denim but I was wondering if I could install XAP files from my PC with this update or its better for me to wait for you to make a video? Secondly, what files should I prepare in the mean time? because my internet connection is not very good so download will take time so please tell me what I can download as preparation for now.

    You can try the documented guide in the WP8.1 Group repository (mega.nz/folder/rBQCQAAA#RL_uGu2CqgeIya6HadZEmg) though if you want to wait for the video version, that's also fine. Both the Windows Phone 8.1 Builds targeted in GDR1 & GDR2 video guides are jailbreak applicable (GDR2 build doesn't support Root but it's rarely used) Lastly about the files, you will need your device original FFU, Emergency files (MBN, HEX), Engineering SBL3 for your model, and lastly Donor FFU (optional) All described in this guide on how to obtain these: mega.nz/folder/yJYzBaBb#Wq6RYEecI7rkwSjtHNLjcA

I don't know about "Emergency files (MBN, HEX), Engineering SBL3 for your model" . . but I guess WPI should be able to automatically download them or you prefer I obtain them from the guide? Yes, I have upgraded to GDR2 already following ur video and I prefer to wait for the video about my lumia 820 spec-a because it is really simple to understand rather than reading guides on google.

    Actually, there is no link between either of them. Astoria package manager (Successor to Astoria package installer) is to manage installing android applications to Windows 10 Mobile Astoria insider builds. It does not deal with typical Windows Phone applications (XAP, APPX/Bundle) Astoria package manager is only to use in Astoria builds, not any others. But the Windows Phone application deployment or WPV Xap deployer (Which is what you meant I guess by "sideload XAP PC software") is created to sideload XAP & APPX/Bundle packages of Windows Phone apps to Windows Phone 8.1, though it works with Windows 10 Mobile as well. (WPV only supports XAPs, WP Application Deployment supports APPX/Bundle but only Windows Phone 8.1 APPX/Bundle packages) Despite the above; If you are in Windows 10 Mobile, you don't have to use any software involving PC to sideload XAP or APPX/Bundle cause there are great installers created to install them right via the phone itself. More info; XAP Installation (W10M): kzread.info/dash/bejne/Y3ph29J9l9u9f5M.html APPX/Bundle Installation (W10M): kzread.info/dash/bejne/pZmo05l7Ya60n7w.html
