Boot loop after flashing Unihertz Titan EEA #45
Comments
Hello, regarding the install, I'm sure that the readme of install take more command than this... |
Right, thanks for the hint with the SP Flash Tool, the software is very poor quality in general and impossible to figure out on its own, and nothing made it seem likely that the software would even work if I can't power it off or properly boot, but some online guide for the exact actions to do at https://romprovider.com/unihertz-titan-firmware-support/ combined with where-ever I got the original images downloaded from seems to have done the trick to restore the device to apparently stock operation.
This is not helpful at all. Firstly, I don't think you're reading the same guide as I am, I was reading https://github.com/rumplestilzken/gargoyle_lineageos20/releases/tag/v1.2 .. secondly vaguely hinting at "more commands" is unhelpful in general. Thirdly the guide itself is pretty poorly written, so it's not exactly clear what are you ACTUALLY supposed to do based on it, and it is clear that actually following the guide does not result in a successful flashing. So e.g. This to me looks like it's got something to do with either Android 9->10 upgrade, or rooting the device which apparently is what magisk is used for. There is not image provided, or any link for where to get it, and the steps above this do not in any way indicate you should be in fastboot mode right now, and my device was not on Android 9, so it does not seem related to installing the image in any way. Then it has stuff for other device, before it says ... and what I wrote was:
.. I added the missing "flashing unlock" command, because as said, following the provided guide does not actually work. Otherwise there are no additional commands related to flashing the Titan in the README that I can tell. After these things it has something about upgrading, which is not related as I've not even booted to it the first time, followed by various other notes etc. that are not related to the flashing itself. So if you @TiTi65 think somewhere here is something I've missed that needs to be done for the flashing to work, please actually say what you think it is that I'm not doing. |
I tried the updated version https://github.com/rumplestilzken/gargoyle_lineageos20/releases/tag/v1.4 and following the guide to make the Magisk -patched boot image, same end result as previously. Clearly that was not the missing magic sauce. |
I've used this: I've done something like: adb reboot bootloader and it works (I've followed the rest of the post after). Regarding SP Flash, it's the only way I know to restore it back, there is a ton of tutorial over internet. |
Hey, similar issue here, Titan OG.
|
So I managed to get mine working just the other day and I've been thinking of writing the steps more clearly, but on a high level this worked on Titan UFS EEA Get (I did not yet verify that these are the exact files I used but I believe these are them)
All the preparations
And then
So specifically for you @amorawski sounds like you also tried Magisk v27 like I did and that's your problem - switch to v25.2 and make sure you check the |
And as a note, people tell me rooting is a mandatory step, even though it is definitely not something I'm interested in, and the install guide just says something like "notes on rooting", indicating it is not very important. |
That was it, my steps do work with Magisk v25.2 and vbmeta setting checked. @lietu I owe you a beer. |
@lietu There are two aspects in your solution that I don't really understand. First, you say that your phone is an UFS one, but the "Android 10 Stock Image" you link to seems to be explicitly an eMMC image (listed under "EMMC Memory" on the page, lacks "-u" at the end of filename). Second, it seems to be an OTA update, and my understanding was that you can't use an OTA version as a base image to restore from scratch. Any thoughts please...? |
Got myself a Unihertz Titan to try LineageOS on a device with hardware keyboard. It was already running Android 10 so I performed the following steps:
lineage-20.0-20230529-UNOFFICIAL-gargoyle_bgN.img.tar.gz
from https://github.com/rumplestilzken/gargoyle_lineageos20/releases/tag/v1.2tar -zxvf lineage-20.0-20230529-UNOFFICIAL-gargoyle_bgN.img.tar.gz
adb
andfastboot
installed and allowed debuggingThen I executed the following commands
flash
took a while but it kept sayingOKAY
for various parts:Now I'm just stuck on an infinite boot loop. When it powers on there's the Unihertz logo, "Powered by android" logo, and very shortly later a very small notice appears saying
This screen stays for about 20 seconds, then the screen will turn off for about 5 seconds, and then it reapperas.
I tried pressing volume up, volume down, the programmable key on the left edge, power button, and the keys on the top row of the keyboard, in various combinations, both tapping them repeatedly, and holding for extended periods of time.
Rather unsurprisingly both

andfastboot
do not seem to recognize the device while it is in this state. On https://github.com/SolidHal/Unihertz-Titan-lineageos-microg/blob/master/README.md it saysDoes not seem to work, but it also does say

Would appreciate ideas on what could be done to
