TASKPHONE T20 unlocking bootloader and custom ROM - Android Q&A, Help & Troubleshooting

hello everyone, new one here,
hope i'm posting in a right place ...
okay so here we go ... i'm about to buy taskphone t20 (in germany they also sold as Land-Rover)
they are sold on aliexpress for 92$ ... and are only ones that come with type c 4gb ram etc... (in that price range)
but it comes with stock android 9 ... so i wanna unlock bootloader and flash either pixel experience or syberia os (didn't decide yet (open for suggestions))
never flashed rom before so my general question is ... how can i flash custom rom when there's no "taksphone" on their list ( i know it sounds funny but i really like this phone)
i already messaged sellers if i can unlock bootloader without a hassle, but in regards of custom rom what should i do ?
in other words what should i do if theres no particular phone i want to rom on developers website ?
thanks in advance

up i guess
these are the specs
p.s. not russian, just couldn't find another review with specs

any input ?

Video Guide : Installing OxygenOS on a Chinese handset.

Hi Guys ,I am still awaiting my OnePlus Two to be delivered but was searching for some info on installing OxygenOS on a Chinese handset running HydrogenOS.
DISCLAIMER - This is not my video , full credit goes to GIZCHINA on YouTube, I just found it on YouTube and thought other like me thinking of buying the Chinese version would benefit.

Hope this helps some of you guys as it seems a lot easier than I had expected.
Edit : Hi guys the phone i ordered from Coolicool had OxygenOS installed from the retailer but is riddled with hidden bloatware. Just a warning for anyone ordering from them.
Thanks
I can confirm that the same works without an issue.
The good thing about two is you dont need to install custom recovery to flash a zip file you can do by booting into the stock recovery

To buy or not to buy? - Questions: RN3pro official MIUI, rooting and custom ROMs

Hi all!
I live in Germany and would like to buy a RN3 pro from Aliexpress. I don't want to stick around with MIUI but would like to try out different CM-based ROMs. The community here seems very alive, but I am confused by certain things. So I hope you can help me :highfive:
1) Some months ago, I followed the news about the Mi4c. People were complaining that Xiaomi won't let them unlock their phones. Are there no such problems with the RN3 pro?
2) Concerning the official firmware: I read that the phones come either with a Chinese or international firmware (or sometimes even bloated by retailers), and each has a hundred of version numbers. Are all versions possible to unlock? Or do I need a particular version to be able to root/unlock bootloader/flash a custom ROM?
3) Are there any differences between the 2/16 gig and the 3/32 gig version of the RN3pro apart from RAM/storage?
4) Is Xposed working fine on CM-based ROMs?
Best regards
1. I spent around a month to get it officially unlocked, till then I unlocked unofficially in few mins. But if you unofficially unlock whenever you flash a rom you must be more conscious and read every step that's given by Developer or else you will end up bricking your device(don't worry there are solutions for very bricking scenario) . So if this is not a concern you can buy
2. Whatever the firmware phone may come with you can flash MIUI global firmware and unlock it from there.
3. Nope not that I know of.
4. Yes it's working.

1)as an unlock reason I pasted some chineese text found in the Internet and after 1 week I got my unlock code. So no problem there
2)Developer rom is recommended for that, but I think that the never versions of stable build also support unlocking. Anyway, it's easy to install developer rom with locked bootloader
3)nope
4)yep

1) If the phone is updated to the latest firmware (7.3.2 at the time of writting) then the bootloader unlocking process time will depend on how long it takes them to approve the permission for you (got my phone on Tuesday and unlocked it today).
2)Yes all are eligible, but you have to be on the latest one. Likely you will get with an outdated Chinese rom and will have to update via MIUI updater (or similar name of the official software). I also suggest looking for the phone from else where, like here in the EU (think ebay.ie had some cheap ones), since i had to pay an extra 50eur for taxes and expenses (am from Lithuania).
3) No idea, likely none. I got the 3gb version because it's more future proof and can upload 2 videos at the same time vie desktop version of facebook. Also the software itself uses about a gig of ram. Plus it's doesn't cost that much more and a gig of ram makes a difference.
4) No idea, wasn't a fan of xpossed before and am not planing to become one.
xposed works on miui? just curious

[help] Lenovo Z5 Chinese room and updates

Hello everyone!
I put myself in a problem here, my mum wanted a new phone and I suggest led Lenovo Z5 as her best option.
I put my money into my alipocket and I was about to buy it when I noticed that there isn't any official international ver of it.
I wouldn't mind the Chinese room if it means I get updates, but I don't know if I can actually install Google play on it..I can't see any info on Zmui
Also if I bought the Chinese ver,will I be able to flash a official international stock rom on it and receive OTA update?
Or will the same idea work if I bought the rooted ver they offer?
about z5
i am a chinese and i bought a Z5 about 3 weeks ago.
The most attractive part of the phone is the 1080P LED screen after using a AMOLED for a long time (worried about my eyesight)
I've never used a ZUI before (i've MI 3 && OP3T). Before buying the phone, my friend tell me about the bad impact of ZUI to his Z2 (AnTuTu Tester remark is lower a lot than a aosp and some roms ) which means the optimization of ZUI may be bad.
After getting the phone, the ZUI annoy me ... Though the ZUI 3.9Ver is based on 8.1 with GAPPS in it, the settings is too poor and the gesture is not well enough. Although with a 6G size RAM, it killed app even you lock it (the utilization is low means most of ram is useless ....). I dislike the ZUI default launcher(ZUI launcher) and replace it with Pixel launcher.
About Root: the phone do not support root or you Warranty is go, but you still have way to root it
About OTA: the rom support OTA if it is not rooted
hmmm last i cannot find any rom like los to flash (that's really shame)
I am really satisfied with the screen ( it must be the best in screen in this price )
Hi
I just bought the phone and it will arrive next week.
I have been really attracted by the looks.
I think I can leave with ZUI.
But tell me how is the performance of the camera both in good but also low light conditions?
Hi i'm from Spain and i love the desing of this phone levono z5 but i want to know if it comes with ZUI i could change it to android, is this posible?

Here's the link in Chinese. https://club.lenovo.com.cn/forum-1490-0-0-reply_time-0-1
Hi, i am assuming you dont like ZUI and want to change to stock android,
Well the phone is still new to the market, i have not seen any developer working on a rom yet, as of now there are no other options then using the stock operating system.
FYI, i am using Zuk z2 pro with custom rom from mokeedev which is also stock android. I got my Lenovo Z5 last week, there is lot of chinese bloatware in there, so i havent switched yet, i am also waiting for a different android operating system. hope this helps.
I bought one from DX.com
You can switch the language to English, but there will be a few Chinese elements (eg. on the keyboard)
These can be easily fixed by installing a 3rd party keyboard, for example.
Mine didn't come with any Google apps but I was able to install the Google Play Store from this APK:

It supports project treble. Some users flashed the stock rom through that. But I think official engineers never try hard in bug fix.
Thanks everyone about the information! If only Lenovo used Stock android like Umidigi Z2! It would have been excellent to use
But is Lenovo z5 going to have a Android P update? If so then wouldn't that optime the phone in the future?
Or is it possible to wait for a working stock android rom for Lenovo z5 ?
Another thing, my mum loves the super bright screen on Lenovo and it's big, she says she wants a lot of her apps running in the background and she needs USB C
I don't trust Umidigi phones, Oppo A5 is over priced with no fingerprint sensor and low ram, vivo phones don't have USB C and xiaomi phones are just darn ugly.
is there any twrp in our lenovo z5?

Lenovo Z5 ROM problem
:crying:Good afternoon, I bought a lenovo z5 arrived yesterday, when I called it I noticed that there was no software of the ZUI, ie, it has a rom that is not for this phone, does not match the notifications with the notch, has navigation bar etc. nothing matches, what do I do? Does anyone know where I can download the appropriate ROM for it?
i bought it at geekbuying
I'm in the same exact situation as Paulacfmsimoes, bought the z5 from geekbuying and it came preinstalled with a butchered frankestein version of the stock rom. Its bootloader is unlocked as well. I'm desperately trying to find a way to install the normal stock rom version, so if anyone has an idea, please help!
Please HELP!!!
I Deleted some important system files on the phone and now it does not torn on.
i did managed to install the TWRP recovery so if one of you guys hes this phone and you can upload me a system backup with TWRP you will save my ass!!
i bought this phone to my girlfriends birthday and now its dead
pleaseee replay and help me
This would be the absolute perfect time for one of you guys to help us out. (both us idiots that bought the phone from geekbuying with that beaten down custom rom and cohavio as well). I anyone with ZUI 3.9 that has the chinese and english version of the rom could make a back-up, that would be awesome!

I don't have the phone yet. But its possible that I will have it for a short time. If you tell me exactly how did you install TWRP (steps and the image of TWRP you used) and a proof that it works I may be able to help you.
If anyone knows chinese, I think I found the solution to all our problems. I stumbled across this forum where the guys have a tool originally designed to unbrick / and or return the phone back to stock.

Install a secured phone custom rom

Hi,
My question is as the subject? Is there any good guides for making a rog phone version 1 with android 9 to be a classified as a secured phone.
Mostly functions that is not necessery will be removed on the phone. Is there any roms you can get tips on? This is testing so, is there any rom that is compatible to Asus rog phone version 1?
Newest stock rom is installed and boot loader is open. Im not the best person at phones and that but can get a given hand when its needed. But im asking you fellows first to choose a custom rom or OS.
The source code and kernel are open to download on asus website maybe we can get a dev or someone can take a crack at making a custom Ron maybe even get 10 . I see no reason other then the phone not being as popular

Which ROM/Android version for a normal phone with gaming sometimes ?

Hi all, just went to grab a XZ1. Was wondering what is the best version / Rom for my use ? AFAIS it is A9, should i go to A10, 11 or 12 ? is a rom more stable / usable than others ? Are there common bugs ? Is this device performing well on GSI ?
I was thinking about A11 LOS on 1st place, but i'm unable to see if this is good. Also i need to change screen then unlock bootloader before, so do not hesitate to tell me if it is impossible.
Thank you, total noob on XZ1 who does not really want to read tons of posts
