Hi, Benötige Hilfe. Nach dem flashen bootet das S2 immer wieder in den Download modus - was kann ich tun?

Mod translation via GT: Hi, need help. After flashing, the S2 keeps booting into download mode - what can I do?

Build #2 2022-06-13
Overall state: Stable
Android build: 12.1.0-r7
Required recovery: TWRP 3.3.1-1
[...]

Thank you and @html6405!

I see that you refer still to TWRP 3.3.1 but is there a specific reason not to use the manual pointing towards TWRP 3.6.1 in OP with this specific build? I was wondering to move finally from LOS 18.1 to this one (running recovery on 3.4.1 if I recall correctly from top of my head).

Simply I didn't try the latest TWRP yet and also because it didn't fit in the recovery partition at first. Now with LOS 19.0-pit it should be possible. And there is a thing with storage.xml which has changed to a binary format causing issues. I think I made a revert commit in frameworks base to restore this xml format. But does TWRP 3.6.1 install LOS 18.1 or 19.0 properly as-is?

Edit: ow wait. I already build 3.6.1... silly me... I just read my own post. I recall my reply. I just copy pasted my previous build texts and forgot I had TWRP 3.6.1 in 2 variants...

Mod translation via GT: Hi, need help. After flashing, the S2 keeps booting into download mode - what can I do?

My guess would be to return the phone to stock firmware before trying again. The variant of firmware to select to download might be written in the download mode screen (I can't remember exactly for that model), or it might be written under the battery cover. If unsure, then best to wait to see if anyone else here on XDA has better advice than I do.
I remember I had to use Odin 3.07 in Windows (run as administrator mode) to communicate with the S2 (i9100) properly

Just wondering how different between the i9100 and teh t989? Would this ROM boot on the t989? I really basically need wifi and camera to use it as an IP webcam. The current t989 cm14 camera driver is really buggy.

Looking to the differences regarding chipset, CPU and GPU alone (totally different!), I am doubting that it is even close to an easy transfer from i9100 to t989. So, I wouldn't place my bets on it but never say never.

Note about new PIT-file: The recovery image of TWRP 3.6.1 exceeds the 8mb partition size of our PIT. That is why I introduced a new PIT-file. I also enlarged the System-partition (FACTORYFS) to 2GB. These are the partition changes (compared with stock) of PIT-file i9100-LOS-19.1.pit :

Partition name	Stock size	LOS 19.1 size
RECOVERY	8MB	32MB
CACHE	100MB	76MB
FACTORYFS	512MB	2048MB
DATAFS	2048MB	12792MB
UMS	11784MB	8MB
HIDDEN	512MB	8MB

[...]

Downloads - TWRP 3.6.1
To install TWRP 3.6.1 you need to enlarge your recovery-partition.
You can download manually the PIT file here.
I recommend to use the "full clean flash"-instructions described above which comes with TWRP 3.6.1.

As I am lacking a Windows with functioning connection via Odin, I would like to re-PIT via heimdall but have done so only years ago and would like to be sure about required steps. Has anyone taken this action with the latest PIT already via heimdall and can help?

I see that also the PDA contains only some images of the total 15 partitions. Would it be sufficient to flash the PIT and the new TWRP recovery? And then reboot to recovery for further actions (format/wipe system/data/cache/...)? I see that kernel is prior to recovery partition and is therefore not affected? Same goes for modem which is not moved by reducing cache size. I am coming from the previously issued PIT (i9100-LOS-16.0-Emulated-Storage.pit).

In doubt (and due to risk of bricking the device), I will stick to TWRP 3.4.0 (not 3.4.1 as mentioned earlier) and flash the latest LOS 19.1 build - I guess it should work as well.

Found my old s2, tried to put the A12 ROM on it but Odin keeps giving me a fail. Don't know why, if anyone could help that would be amazing.

Simple things first: are you sure it's the GT-I9100 S2? There are many variants of S2 so it can get kinda confusing

I realized it's the i727 model
Do you know if there's a ROM for this one?

 

[hieppo]

I wish too. The title should be changed to i9100.

Well ... "[ROM][UNOFFICIAL][12.1.0][r7][I9100] LineageOS 19.1 [ALPHA]" includes I9100 with a capital "i". Or am I missing something?

Oops, I made a mistake, I went from the high level category of Samsung S2 and completely neglected the i9100 part. My bad. But still disappointed that the ROM can't be compiled for other sII variants.

Well, same as the question about the t989, the differences of your i727 vs. the i9100 are so massive that it is far beyond "just compiling" it. But the two of you might want to team up as both are way closer than the i9100.

Thank you for giving me the right direction / confirmation to give it a try! In the end, it is a single line to repit and flash recovery with heimdall from the shell:

sudo heimdall flash --repartition --pit i9100-LOS-19.1.pit --RECOVERY twrp-3.6.1_9.0-i9100.img --no-reboot

After that reboot to recovery:

• Wipe -> Format Data
• Wipe -> Advanced Wipe -> Davik / ART Cache, Cache, System, Preload, Non-emulated Storage
• Flash desired ROM

That is what worked for me. More details in the two links provided by mirhl and also here about what a PDA file contains.

Not reproducible observation: On the first attempt following the above steps, "internal storage" was located in "/data/media" and was not linked to "/sdcard". On the second attempt, "internal storage" was located in /data/media/0" and was linked to "/sdcard".

Reproducible observation: On the first boot after installation, the phone is stuck on the initial boot splash for more than 5 min. I had to force shutdown once and boot again to get into LineageOS 19.1.

Other observations:

• Same as on other LineageOS 19.1 builds (my reference OnePlus 5), USB debugging is active. Can be deactivated in developer mode. Also, USB connection mode selector is only accessible thru the settings menu - no shortcut upon connecting USB cable.
• As the very initial screen is already a bit tight for the standard LineageOS 19.1 greeting (see image below), one might be missing that the buttons to proceed are below and you need to scroll. I was a bit confused for a moment.
  
  

So, no further nagging on details but want to share for others as information. I am very thankful to everyone who makes it possible to run Android 12.1 on this ancient phone!

[...] So, no further nagging on details but want to share for others as information. [...]

Again not intended as picking on details but plainly sharing as information for others and to decide for rINanDO whether to fix or not:

• Default, display timeout is "null" - nothing selected.
• When changing the battery icon in "status bar" (not sure about translation), this will not be reflected in the quick access drop down menu (standard battery icon without percentage is kept whatever you set).
• Normally not using the Chromium based browser, I missed almost in the default dark design the dark grey dialog text on very very slightly less dark grey background - e. g. "delete" / "OK" / "cancel" / ... in pop ups in settings and so. I guess rather something of LineageOS while I can't recall having seen this with other devices.

Another interesting observation - no clue whether already the case with previous LOS versions: While being in flight mode but WiFi on, I noticed 213 % battery usage by mobile network. 213 % sounds just a little bit too much under these circumstances ... But as I wasn't 100 % sure that I had the phone from the start in flight mode, I did another test (charging to 100 %) which resulted still in battery usage caused by mobile network. I started to wonder whether WiFi is categorized as mobile network and did a last test with WiFi off and still (only) mobile network battery usage was indicated.

Is this "by design correct" - e. g. linked to old kernel not supporting this reporting function properly - or is the mobile network not completely off in flight mode due to some bug?

No disaster for me but I was surprised after all.
