[Lenovo Legion Phone Duel 2] dEFLASH:
Send me the serial and imei1 screenshot in PM, also your email to get sn.img for unlocking bootloader.
[Lenovo Legion Phone Duel 2] Shadow27Jirka:
So I was finally able to unlock the Bootloader! It took like a week until unlocking web page worked for me.

I´ve unlocked it correctly, bootloader is saying its unlocked, Chinese ROM is refusing to deliver me any OS updates (as they state it will).

I´ve used QFIL to flash Global ROM using standard process I described in this Thread.

Phone boots but again, it is in state described two posts above (here): It boots into OS but shows a message saying that this OS version cannot run on this HW.

I think someone needs to take the official Global ROM and remove this hardware related check. We wont be able to use Global ROM on this phone until it happens.
[Lenovo Legion Phone Duel 2] dEFLASH:
Need to find some china specialist :)

AliExpress stores selling CN flashed to global, info 100% but they keep secrets :(
[Lenovo Legion Phone Duel 2] Shadow27Jirka:
I´ll try some other stuff with QFIL and Global FW, but I´m not sure. If you´ll try to look for someone from Ali, then it´d be really great!
[Lenovo Legion Phone Duel 2] dEFLASH:
Tried...

nobody speak nobody get choked
[Lenovo Legion Phone Duel 2] Shadow27Jirka:
Well then I guess someone will probably need to decompile the ROM or something like that (dunno how it works exactly).
[Lenovo Legion Phone Duel 2] t-mobile_mda:
hey guys..

finally this device convertable to Global rom with unlocked bootlaoder..?
[Lenovo Legion Phone Duel 2] bs3pro:
Yes, but don't waste your time. Phone is a POS. The cn version is missing many bands for TMO also.
[Lenovo Legion Phone Duel 2] Shadow27Jirka:
So you were able to boot up CN phone with Global ROM? How?
[Lenovo Legion Phone Duel 2] bs3pro:
Its been talked about all over. read, read, and read again.
[Lenovo Legion Phone Duel 2] Shadow27Jirka:
Where? All I can see is that its not yet possible...
[Lenovo Legion Phone Duel 2] Dark11789:
I have unlocked bootloader but when I flashed the global rom, the same problem persists
[Lenovo Legion Phone Duel 2] Dark11789:
I have unlocker bootloader but still have the same situation
[Lenovo Legion Phone Duel 2] bs3pro:
Flash back to CN.
[Lenovo Legion Phone Duel 2] king of demons:
how Unlock bootloader ??

i want Flash it to Global to CN ROM
[Lenovo Legion Phone Duel 2] pramodppd:
I unlocked boot loader

Flash global

Still the same error software not compaitable with hardware
[Lenovo Legion Phone Duel 2] mitman93:
Yup. Same here. Have an unlocked bootloader and have been trying to get back to Global for over a month now with no luck. Phone only works when CN ROM is flashed. Have tried literally everything (including reaching out to Giztop, where I purchased the phone, and having them send me the exact ROM they used, apparently is just the standard ROW Global one)

Giztop/Ali are indeed using some undisclosed method to bypass this hardware check, and when I asked them how they did it, I stopped receiving replies LOOOOL.

I wouldn't even mind just using the CN rom, as I'm fully rooted and can load up all the Google Play services myself, except...because the GSM bands are different, dataconnectivity is HORRIBLE. I have T-mobile and it constantly drops calls / connectivity. It's unusable. So yeah, for about a month now this phone has just been an awfully expensive paperweight for me.

If anyone on here knows how to bypass this hardware check for the CN model, I would forever be in your debt.

What version of qfil are you using? I keep getting an error message saying Sahara fail process fail

Did u have bckup qcn file for lenovo legion 2 pro. Can u send to me if possible. I hae no service n fingerprint problem. I need to restore qcn file😢
[Lenovo Legion Phone Duel 2] Dimon(88):
Hi, I also need a qcn file. Have you found it?
[Lenovo Legion Phone Duel 2] Shadow27Jirka:
Hello guys, anything new regarding changing CN ROM to Global one?
[Lenovo Legion Phone Duel 2] Mr.PvT:
Did you fix the error yet? I had the same problem, even though I unlocked the bootloader
[Lenovo Legion Phone Duel 2] Mhyho:
As I searched in Chinese fourms, It seems to flash Global ROM over CN, we must (1) unlock bootloader (2) backup qcn file, edit it and restore it (3) flash.

I found a way to backup qcn file on: https://www.bilibili.com/video/av371118105, It needs root, uses adb shell to force phone open COM5 port so that QFIL can backup and restore qcn files.

And theoritically, we should follow a Korean's instruction on: https://ruinses.tistory.com/2652?category=699524, use HxD find the code that locks the phone in CN, edit it to Global.

However, Duel 2 may be using a different way to lock in CN in qcn, I can't find the Hex-values the Koeran shows. that's the problem.

So is there anyone have a Global Phone to backup a qcn file for us? Most apprieate. I would compare it with CN qcn to find out deferences to ensure how to edit CN qcn to Global qcn.

Or is there anyone knows how Lenovo locks qcn in CN?
[Lenovo Legion Phone Duel 2] Mhyho:
by the way, any CN bricks can use this ROM to relive your phone, also found in Chinese fourms: https://meta.box.lenovo.com/v/link/view/26fcb21557f64108a4ba7c3a723f5298

It's ZUI 12.5.535
[Lenovo Legion Phone Duel 2] &(*):
Do you have a Saviour/Legion Pro 2? Can you provide a QCN backup with your IMEI's/WiFi/Bluetooth and device serial removed? I read the link you provided of the tutorial in Korean and it states you cannot switch back from Global to CN once it has been switched; however, I believe if you have a back of the QCN before you modify it, you should be able to restore it and swap back to a CN build successfully.

[Touch Cruise ROM Development] 5tef:
Hi,

i've got a bug with this cool ROM :o: Alarms don't work ! :(

last night, i program 3 alarms, and i noticed the "alarm notifier" on the Today Screen was always on "Alarm OFF"....

and this morning, no alarm ring ! :eek:

a solution ?
[Touch Cruise ROM Development] sedde:
well i had mine on too, and after 2 days magically it started working, and no i am not joking
[Touch Cruise ROM Development] Svenvdmeer:
Seriously there are two topics about this rom and i guess this bug has been mentioned more than ten time so i think i and a lot of other people would appreciate it if you would use the search function.
[Touch Cruise ROM Development] 5tef:
i found only this :

"alarm IS working correctly just Alarm On/Off light in Today screen works differently from previous ROMs. It shows only today's active alarm. For example, if you selected alarms for all week, except today, then Alarm light will turn off even so you have alarm tomorrow."

i use my Cruise to wake up all days at 6:30 AM.... how to setup my alarm ?

Yep, I followed that guide and searched the thread for my problem but nothing that worked for others has resolved my problem and nobody had the exact same problem. Also going into fastboot which solved the communication issue for others is not an option because fastboot isn't working on my device.
[OnePlus 8 Pro Questions & Answers] varunpilankar:
Is your fastboot working?
[OnePlus 8 Pro Questions & Answers] iredecent:
No it isn't. The only things I am abled to access are Crashdump mode and EDL.
[OnePlus 8 Pro Questions & Answers] varunpilankar:
When you connect to EDL mode what do you see on Device Manager?

Also, which port are you using to device your device? USB 3.0 or 2.0?
[OnePlus 8 Pro Questions & Answers] iredecent:
When I connect my device in EDL I see Something QLoader 9008. I don't know the exact thing off the top of my head. This should be the right thing from my research on the topic.

I've tried multiple ports USB 2.0, 3.0, 3.1 even USB-C to USB-C.

[Xiaomi Mi 11 Lite 5G] 4K2K:
It has been a week since I started using this phone and here is my review:

- So light and so thin. There is no other phone like it.

- Everything is very smooth and fast.

- No heating issues. I usually take a break when I first setup a phone (large file transfer, mass installation of apps...etc.) for I do not like holding a hot chunk of glass, plastic, or aluminium. I did not experience that with this phone.

- Display quality is excellent. My last phone had deltaE score of 1.4 and I assume 11L5G is probably in that area too. In other words, near perfect white balance and color reproduction.

I am not sure if I have the pentile or the other inferior display. All I know is that it is indistinguishable from AMOLED used in S10 Plus and top notch LCD screen of my previous phone.

- Camera. It has noticeable and annoying lag in low light situation. I am not talking about dark dark settings but just indoor situation. I press the shutter then it takes a photo just when I start wondering if I did not press the shutter button. Since such shutter lag is just a strange problem I never experienced on other phones, I expect it to be fixed on next update.

- Build quality is quite good and its back panel looks very premium.

- Vibration motor is excellent. This is the one area where manufactures cut corners and I am glad it is the not case this time.

- Widevine L1 even after unlock. But you cannot install NetFlix from Playstore but APK install works fine.

Overall, I am very much pleased with this phone. If you want a phone that is light and thin, you have no other choice but to go with this one. Ever since introduction of 5G, the market kept pumping out thick and heavy phones. Xiaomi too until this phone. What's great is that this phone is not just light but comes with great CPU, display, large battery, build quality, vibration motor and everything. It would've been perfect if no shutter lag issue. I do expect the issue to be fixed since it cannot possibly be a hardware problem.

EDIT: I retract what I said about display quality. It is, indeed, distinguishable from AMOLED used in S10 Plus or my previous phone which uses LCD with 441 ppi. Text do not appear as sharp as those. It is micro blurry and you may not even notice it if your sight is not so very good. I am still not sure if my phone came with pentile or delta though.

[Xiaomi Mi 11 Lite 5G] JoudaCZE:
I'm having the same issue. Last week I have ordered the Mi 11 Lite 5G and when watching videos (War Thunder for example) the lack of details in those videos is big compared to my Redmi Note 8 Pro. The screen is also slightly brighter and discoloured. That probably means we have the RGB Delta screen.

Hi,

I'm planning to buy a Mi 11 lite 5G.

What about battery life ?

Olivier
[Xiaomi Mi 11 Lite 5G] 4K2K:
Battery life is highly subjective - everyone's usage patter is different.

AccuBattery Battery Health shows that my device has 3561 mah estimated capacity. And it gets me about 10h 30 min. of on screen time. Note that I do not game and use phone mainly for browsing stuff and apps that are not heavy.
[Xiaomi Mi 11 Lite 5G] zazzeck:
I am very disappointed about it. The capacity of the battery is only at 90%. I have to reload several times a day. My old Poco F1 lasts longer.... With the same apps.
[Xiaomi Mi 11 Lite 5G] pantale:
I don't use my phone too much. Currently, I have a Oneplus 5T that is almost 5 years old and I only charge it every couple of days, so I hope to do the same with this one.
[Xiaomi Mi 11 Lite 5G] dy2592:
I came from a oneplus 5T.

5T I could not get past a whole day without charging once, warp charge is still fast but still.

Mi 11 lite I can go the whole day and it charges fast if needed.
[Xiaomi Mi 11 Lite 5G] pantale:
Yes, fast charge is very efficient, with 33W it's better than the OP5T with 20W.
[Xiaomi Mi 11 Lite 5G] GuGuGal:
I have an issue with Bluetooth, it doesn't automatically connect to paired devices like my car (most importantly), speaker or laptop.

I have searched for a solution on Internet but couldn't find a fix. BTW same problem on my Poco F2 pro and Oppo X2pro. All are global rom.

Has anyone a solution for this problem?

Hi there!

I've bought a Bosion HU (4gb ram 64 rom chipset ac8257) and works really well compared to my previous unit (PX5 2gb ram). I've registered at 4PDA forum to get some information about software but I can't find too much info about this unit..Any experience with this kind of software? I get used to the PX5 units so now I'm completty lost about this new chipset.....MCU...

Thanks in advance.
[Android Head-Units] amplifier1980:
hey. i know its an old thread but I ve got the bosion HU.., already followed the almost dead thread at 4PDA Forum also. This head unit is crap, honestly spoken, do you have an idea if there are alterntive firmwares maybe from other manufactures that would work with the boison units? my BT calling feature stopped working after last update what has been talked about at 4PDA also. In addition I do not like much the apprearnce of the start-screen and many other minor issues too... now I am in hope that somebody has found a good working alternatively firmware file that is way better than the boison one? sorry for my bad english..
[Android Head-Units] solmer:
Hi! Same situation on my side.....I've tried another Android units before and this one it's not bad....I've not found another compatible firmware....If you find something please post it :)
[Android Head-Units] AML276:
I've just purchased this ac8257 b200 unit and I'm NOT loving it. My px5 with frequent wifi dropouts is preferable.

Does anyone else have an issue with the accessibility downloaded services being disabled after a short period? I've added the apps to be excluded from Battery optimisation and ensured battery saver is off and even made the apps device admins if the app can be but within an hour the services are disabled.

Also, Google voice typing seems to be like the old android 6 version with the big grey rectangle covering the lower half of the screen while listening for voice input and if it fails because the internal mic is crap I can't get it to cancel to go back to the keyboard. I usually have to exit the app and relaunch it.

UPDATE: Apparently Duraspeed is a separate task manager/battery optimisation app that comes with these units. I've now tried turning that off as well as enabling it and adding the apps as exclusions and the downloaded services are still disabled after a short period.

Google Maps also runs much slower than my previous 4Gb px5 unit.
[Android Head-Units] AML276:

Just wondering if the green tint issue synonymous on Samsung 2020 panels has continued its trend onto the S21U? Asking for a mate.
[Samsung Galaxy S21 Ultra] enigmaamit:
Hi.

Haven't noticed any green tinting on my panel yet. Even on the lowest brightness. There is a teeny tiny smidge of motion smearing at the minimum brigntness when scrolling dark web-pages, but that's about the only fault I can find with the screen so far.
[Samsung Galaxy S21 Ultra] Limeybastard:
That’s good to know. Thanks.
[Samsung Galaxy S21 Ultra] iamnotkurtcobain:
I had the S20 (6 different devices). All had a green/red tint issue. The S21 Ultra has a much better display. Mine at least.
[Samsung Galaxy S21 Ultra] Limeybastard:
Yeah. One of my Note 20 Ultras was more green tintish than the other. I couldn’t stand it, the Oneplus 8 pro also had it slightly. As did the iPhone 12 Pro Max. Thanks for sharing your experience.

[Samsung Galaxy S21 Ultra] oae08:
I had the screen show a like a green background for split second , does this mean the screen is starting to get faulty or is it a software issue? I had this phone since launch (for about 4 months now)
[Samsung Galaxy S21 Ultra] enigmaamit:
If it was a one-time occurence, it could be due to anything. Difficult to diagnose it based on a split-second incidence. If it doesn't happen again, don't worry about it. But if the same issue keeps occuring, then it may be worthwhile investigating.
[Samsung Galaxy S21 Ultra] oae08:
Its a one-time thing for now, but it got me scared. especially since I am currently having another issue with the phone (its crashing and rebooting randomly).
[Samsung Galaxy S21 Ultra] enigmaamit:
I saw your post in the other thread. This wouldn't have been a cause of concern in isloation but if you add your reports of system crashes and erratic behaviour, there may be something serious wrong with your phone under the surface. Would'nt be the first time this has happened to someone (at least not me).

This is exactly the kind of situation warranty is for.

I cannot profess to know what you should do next but i can only tell you what I would do faced with your situation. And that is to head to the nearest service centre and explain the issue and ask for a resolution. If that fails, escalate it upwards.
[Samsung Galaxy S21 Ultra] Limeybastard:
Looks like I jinxed myself by creating this post before receiving my device. Since I got it yesterday it has a very aggressive green to pink tint when slightly tilting the viewing the angel. I sent it back. The lord taketh away green tint and replaced it with this LOLzzz.

I have searched and searched and couldn't find a thread concluding this issue with a solution.

I know some roms (as i've tried some others) DO include Orange 2G and Orange 3G.. so i guess it's somewhere in a ROM file or reg string.

Thanks in advance for any help.
