[Galaxy S II Q&A, Help & Troubleshooting] danida2:
Hi everyone

I need some help migrating my Galaxy S2 to lineage OS. A year or more ago I installed Cyanogen 12.1 successfully (when I also repartitioned the memory) and everything was/is working fine. Now I want to migrate to Lineage OS but I am stuck.

The main problem seems to be that the phone now has Cyanogenmod recovery which does not recognise the signature of the LineageOS new image. So I try to replace the Cyanogen recovery with TWRP but it doesn't work. In particular I follow the instructions here

https://xdaforums.com/galaxy-s2/orig-development/isorec-isolated-recovery-galaxy-s2-t3291176

but the adb push twrp-3.1.0-1-i9100.img /dev/block/mmcblk0p6 command doesn't work - I get 'Remote permission denied'.

Could this be because of the repartitioning I did when I installed CM 12.1? I don't remember exactly what I did but I think I configured a partioning of 4G data, 1G apps

If I do an adb shell into the phone (enabled debugging and root access) the mount command I get (among others)

/dev/block/mmcblk0p9 /system ext4 ro,seclabel,noatime,user_xattr,barrier=1,data=ordered 0 0
/dev/block/mmcblk0p7 /cache ext4 rw,seclabel,nosuid,nodev,noatime,errors=panic,user_xattr,barrier=1,journal_async_commit,data=ordered 0 0
/dev/block/mmcblk0p1 /efs ext4 rw,seclabel,nosuid,nodev,noatime,errors=panic,user_xattr,barrier=1,journal_async_commit,data=ordered 0 0
/dev/block/mmcblk0p10 /data ext4 rw,seclabel,nosuid,nodev,noatime,errors=panic,user_xattr,barrier=1,journal_async_commit,data=ordered,noauto_da_alloc 0 0
/dev/block/mmcblk0p12 /preload ext4 rw,seclabel,nosuid,nodev,noatime,user_xattr,barrier=1,journal_async_commit,data=ordered 0 0

df command gives

Anyone has any suggestions how I can proceed to install TWRP to get to upgrade the OS?
[Galaxy S II Q&A, Help & Troubleshooting] danida2:
OK, I got past the "Remote permission denied" step by doing an "adb root" first, but still no joy. That is, if I push the recovery and then issue a "adb reboot recovery" still the CM recovery comes up

Any suggestion would be appreciated...

Hi everybody.

I know how to verfiy if a wizard is a G3 or a G4.

But i have a wizard from a friend of mine (T-Mob. MDA Vario) and it has the latest T-Mob. Rom (Aku 3.3) with IPL/SPL 3.08.

But the Wizard Service Tool (http://xdaforums.com/showthread.php?t=295038&page=1) tells me its an G3 device. I know that my friend bought one of the first MDA Varios and have updadted a few months ago with T-Mobile Updater. So is G3 or G4 a hardware issue or is the only point to verify IPL/SPL >= 2.XX.000X?

I am a bit confused.
[G4] shadow2000:
Any hint for me?
[G4] Innocent Hate:
Check the IPL / SPL just like the sticky says. I'm pretty sure it's hardware dependent if it's G3 or G4. I have two Wizards, once is G3 and one is G4, I knew that when they were purchased, and the SPL confirms it on both.
[G4] zabardast_1:
G3 and G4 have different Hardwares, DOC chip versions on both are different. IP/SPL are the Bootloaders,A G3 DOC chip version has an IPL/SPL 1.xx or 2.xx.xxx but a G4 device has IPL/SPL 2.xx.xxx1,note the difference.

Cheers!

Thank you so much for the link! :) At first i waited months for Nougat OTA update in Finland but it was nowhere to be seen. Then i tried some SD card update methods but all my previous attempts failed for some reason but now using that update package behind your link, i finally have frikkin' Nougat :D So i updated straight from v1.0.0B12 to v1.2.0B12. Nougat also brought Hi-Fi audio option for ZTE music player, nice! I don't know about you but when i was on 6.0.1 MM, that startup melody was WAY TOO LOUD but now it's much more quiet so that's a nice little thing.

Which one is the best and newest - B13? Is this the same as german B13 version? I use my device in Poland and the 1 june 2017 B09 update didn't have good translation.

Anyone had issue with this file? Every time I unpack it I get the error message at the end: The archive is corrupt. I downloaded the file 3 times
[ZTE Axon 7 Mini Questions & Answers] oyobass:
You may have already done this, but have you unzipped the file and extracted the 'update.zip' file and placed that in the root directory of your SD card?

The first few times downloading the European updates, I was following the US directions and just renaming the downloaded file 'update.zip'. I didn't know there was a zip file inside the zip file...
[ZTE Axon 7 Mini Questions & Answers] priority1:
I got the error when unzipping the file
[ZTE Axon 7 Mini Questions & Answers] oyobass:
Several people have had to download the file several times in order to get a working copy, (raises hand- it took me half a dozen attempts).

If you are in Europe, there are several ZTE sites you could download the file from. From reports that I have seen, most of europe, (excluding the UK), is on the same firmware. The Spanish site worked perfectly for me. (I'm in the US, but my phone is a global phone from Gearbest).

ZTE opted not to have that feature in Nougat. Crazy but true!
[ZTE Axon 7 Mini Questions & Answers] priority1:
I'm having more issues with Nougat 7.1.1. The first thing I noticed is that Google Pay stopped working. Every time I launch Google Pay, it force closes in a second. A small window pops up with a circle spinning in the middle. Then I'm prompted to re-enter my password and sign in to my Google account. When I put in my Gmail it says: This account already exists on your device. From there I can't progress. Also, my gmail profile photo is mysteriously gone and I can't update it on my phone. When I click set profile photo in Gmail setting, an error comes up: couldn't save profile photo. Strangely when I log in to my Gmail on my laptop, the profile photo is still there.

I tried downgrading to June 1 2017 security patch but the issue still remains. I also tried removing my Gmail and Google Pay, then re-adding Gmail and re-installing Google Pay. Nothing seems to work.

I can't even take a bug report. When I enable Developer Options, USB debugging and Bug report shortcut, The Take a bug report is missing under Developer Options, and there's no shortcut in the Power Menu.

How to get the V1.2.0B16 update

Good news for all Axon 7 Mini owners, who wants to get the V1.2.0B16 update:

Go to: https://www.ztedevices.com/en/support/detail?id=C356F0B365C14CB6838E2664A1BED299

And download: 340060B1271ZTE B2017GV1.2.0B13 SD card software package.

If you have B15 firmware, just downgrade to B13 (downgrade will not erase your data). Once successfully downgraded, just go to menu and search for OTA updates. Voila, version B16 is ready to be downloaded and installed:

;)

Android security update on B16 is 2018-07-01.

Just put it on your SD card and perform update. ;)
