Has anyone successfully installed the CN build? Even after unlocking the bootloader the system error appears. Any help would be appreciated as to how to get this successfully back to a Lenovo Pro 2 CN from a Duel 2 Global.
[Lenovo Legion Phone Duel 2] kofijordan:
im in fastboot any one got the lenovo legion pro 2 stock firmware?
[Lenovo Legion Phone Duel 2] &(*):
@kofijordan ,

Above a few posts there is a link for the bundle: https://meta.box.lenovo.com/v/link/view/b7dd980e0e874b58b2a6d683ad63adac

Try and post results.
[Lenovo Legion Phone Duel 2] kofijordan:
i flashed this one already and it didnt change anything. what ill try is a Full erase partition then try the flat build option and see how it goes
[Lenovo Legion Phone Duel 2] &(*):
@kofijordan , what is the issue the device is having? Does it not even reach the bootanimation or is it posting system incompatible on boot? The bootloader must be unlocked if switching between the two models due to the bootloader not having the correct keys nor anyway to update the table (secureboot, which is not disabled when unlocking the bootloader).

You can use the bundle with Lenovo's RSA, follow the steps by @x.0ldB0y.x first before resorting to flat build through OFIL:

Download Chinese ROM from link above https://meta.box.lenovo.com/v/link/view/b7dd980e0e874b58b2a6d683ad63adac

Open Lenovo Smart and Rescue assistant and let it download Lenovo L70081 ROM

Open folder with downloaded ROM from Lenovo Smart and Rescue assistant - you should see bunch of extracted ROM files

Go directly into the ROM Folder what namend "L70081_ROW_SECURE_USER_......"

Delete all files (abl.elf, aop.mbn, and so on) from that ROM folder

Extract Chinese ROM folder and go into the extracted Folder named "L70081_CN_SECURE_USER_......"

Copy all the files from inside the folder "L70081_CN_SECURE_USER_......" to the Folder "L70081_ROW_SECURE_USER_......"

Run standard Rescue process in Lenovo Smart and Rescue assistant

After this, device will have Chinese ROM and will be booted in this ROM.
[Lenovo Legion Phone Duel 2] kofijordan:
okay ill try this mine reaches the boot screen just powers off after and my bootloader is unlocked
[Lenovo Legion Phone Duel 2] kofijordan:
okay i tried it the phone came up to the usual startup screen stayed there a like 3o secs then it rebooted then it blinked and turned off

my phone requires to be plugged in to come on is that common?
[Lenovo Legion Phone Duel 2] kofijordan:
Well this is what's happening starts up like normal the vibrates and turns off then goes into that crash dump
[Lenovo Legion Phone Duel 2] &(*):
Since your bootloader is unlocked it will be a bit easier to try some workarounds:

Try this first:

fastboot getvar all

now check which slot is current (a or b),

now copy to platform-tools and flash the vbmeta.img && vbmeta_system.img from the bundle you downloaded (12.5.591),

fastboot --disable-verity --disable-verification flash vbmeta_(a or b) vbmeta.img

fastboot --disable-verity --disable-verification flash vbmeta_system_(a or b) vbmeta_system.img

If the above doesn't work your boot.img might be corrupted which should be an easy fix, copy it into platform-tools like you did with the above vbmeta.img(s) and,

fastboot flash boot_(a or b) boot.img

Maybe downloading the Duel 2 bundle with RSA and flashing it will fix the issue, at this point it would be the more than likely best chance if your patitions are somehow not right and it won't harm the device considering the bootloader is unlocked (doesn't really harm it with it locked either).
[Lenovo Legion Phone Duel 2] kofijordan:
Okay cool I'll give it a try
[Lenovo Legion Phone Duel 2] kofijordan:
there is only vbmeta_system.img no vbmeta image
[Lenovo Legion Phone Duel 2] kofijordan:
Do you have telegram? it would be easier to contact and follow you from there
[Lenovo Legion Phone Duel 2] &(*):
No, I don't do have a telegram account. The 12.5.591 bundle has both a vbmeta.img and vbmeta_system.img. Is it posting an error on console with fastboot? If your boot slot is

a

use

a

, as the rest of the slots are also set to the same slot for mounting partitions. If all else fails, use Lenovo's RSA and download the 70081 Duel 2 12.5.188 build (Hong Kong SAR, China). and flash it to see if it will boot.
[Lenovo Legion Phone Duel 2] &(*):
Okay, I think I know what's happening, try instead:

fastboot flash vbmeta vbmeta.img

there might not be an a/b partition for it
[Lenovo Legion Phone Duel 2] kofijordan:
I'll try it can you link the 12.5.591 firmware so I can find it
[Lenovo Legion Phone Duel 2] &(*):
https://meta.box.lenovo.com/v/link/view/b7dd980e0e874b58b2a6d683ad63adac

One other thing you might want to try, within fastbootd (you access fastbootd when you instruct it to fastboot reboot fastboot), format data
[Lenovo Legion Phone Duel 2] kofijordan:
huh?
[Lenovo Legion Phone Duel 2] kofijordan:
i did all the flashes still nun
[Lenovo Legion Phone Duel 2] kofijordan:
Got this just now after the factory reset it goes back to crash log
[Lenovo Legion Phone Duel 2] kofijordan:
Tried the Sar china still no boot
[Lenovo Legion Phone Duel 2] &(*):
@kofijordan

Try,

fastboot format userdata_a

fastboot format userdata_b

or just

fastboot format userdata

followed by

fastboot format cache_a

fastboot format cache_b

or just

fastboot format cache
[Lenovo Legion Phone Duel 2] kofijordan:
in fastbootd?
[Lenovo Legion Phone Duel 2] &(*):
If you type in fastboot getvar all does it post output?

Try the official Google version of platform-tools: https://developer.android.com/studio/releases/platform-tools
[Lenovo Legion Phone Duel 2] kofijordan:
yes

one sec
[Lenovo Legion Phone Duel 2] &(*):
And you are using the side port of the phone not the bottom I assume?
[Lenovo Legion Phone Duel 2] &(*):
try fastboot --set-active=b

try to see if it boots,

if not set it back to a: fastboot --set-active=a

then try to boot
[Lenovo Legion Phone Duel 2] &(*):
I see there is not a system slot, wondering if that is the reason it won't boot
[Lenovo Legion Phone Duel 2] kofijordan:
Could be the reason
[Lenovo Legion Phone Duel 2] kofijordan:
When I set it to slot b and reboot it goes into edl
[Lenovo Legion Phone Duel 2] kofijordan:
Side port
[Lenovo Legion Phone Duel 2] &(*):
You could try flashing a GSI A/B image: https://sourceforge.net/projects/an...20220315-UNOFFICIAL-arm64_bvS.img.xz/download

fastboot flash system (name-of-extracted-system.img)
[Lenovo Legion Phone Duel 2] &(*):
you will need to do the following commands before booting a GSI system

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

fastboot --disable-verity --disable-verification flash vbmeta_system(maybe needs slot _a) vbmeta_system.img

then

fastboot flash system (name-of-extracted-system.img)
[Lenovo Legion Phone Duel 2] &(*):
Power it off (hold power for like 30 secs) then hold volume down button and power on, should be in bootloader again,

fastboot --set-active=a
[Lenovo Legion Phone Duel 2] kofijordan:
nope not coming out of edl
[Lenovo Legion Phone Duel 2] &(*):
try holding both volume keys and power button see if it shuts off and then flashes the boot screen for a split second, being in EDL will at least allow you to enter flash mode at which point you can reflash through RSA (or QFIL if that's what you have been using). I think also while in EDL you can instruct it through

adb shell, such as: adb shell then reboot bootloader
[Lenovo Legion Phone Duel 2] kofijordan:
no flash screen just switches off n back to edl
[Lenovo Legion Phone Duel 2] kofijordan:
and rsa flash didnt wrk
[Lenovo Legion Phone Duel 2] &(*):
did you try adb commands?

adb shell

reboot bootloader

or

reboot -p

what appears on the screen, an android logo with an exclamation?

it has to be powered down and then hold both volume keys and power it on, screen will light up for a split second, then flash it through RSA or if all else fails use QFIL with these instructions posted by Shadow27Jirka

Open QFIL

Select Meta Build

Select Programmer path as "prog_firehose_ddr.elf" from extracted Chinese ROM files

Load Content.xml from Chinese ROM files ("contents.xml")

Press Download

Switch phone to Download mode (press and hold all volume and power buttons for a while and the plug a cable to side USB port)

Download will start automatically and it´ll flash whole OS

If step 5 will not be enabled, use step 6 and press Download right after phone is detected by QFIL

Post some pictures of your QFIL setup before flashing so I can confirm you have the right settings applied
[Lenovo Legion Phone Duel 2] kofijordan:
nope nun
[Lenovo Legion Phone Duel 2] kofijordan:
nun at all
[Lenovo Legion Phone Duel 2] &(*):
I think it's not powering down, hold the power down key until it shuts off. Test with it plugged into the charger
[Lenovo Legion Phone Duel 2] &(*):
DId you select your com port in QFIL when trying to flash?
[Lenovo Legion Phone Duel 2] kofijordan:
i flased it over with qfil
[Lenovo Legion Phone Duel 2] &(*):
QFIL worked?
[Lenovo Legion Phone Duel 2] kofijordan:
lol back to qualcomm crash dump and fastboot mode
[Lenovo Legion Phone Duel 2] &(*):
Now do this and see if we can at least make it boot something:

grab this GSI: https://sourceforge.net/projects/an...20220315-UNOFFICIAL-arm64_bvS.img.xz/download

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

fastboot --disable-verity --disable-verification flash vbmeta_system vbmeta_system.img

then

fastboot flash system (name-of-extracted-system.img from above)
[Lenovo Legion Phone Duel 2] kofijordan:
Downloading it rn so when it's finished I'll try it
[Lenovo Legion Phone Duel 2] kofijordan:
Do you have a system where u can remotely try it and I can pay to get it fixed via PayPal or sum?
[Lenovo Legion Phone Duel 2] &(*):
Assuming you can't extract the .xz format? Use 7-zip: https://www.7-zip.org/
[Lenovo Legion Phone Duel 2] kofijordan:
i got 7zip
[Lenovo Legion Phone Duel 2] &(*):
Flashing the system through fastboot didn't work?
[Lenovo Legion Phone Duel 2] kofijordan:
still downloading
[Lenovo Legion Phone Duel 2] kofijordan:
Nope
[Lenovo Legion Phone Duel 2] kofijordan:
Fastbootd flashing works gonna see if it boots
[Lenovo Legion Phone Duel 2] kofijordan:
It finished but still no boot
[Lenovo Legion Phone Duel 2] &(*):
Try again:

fastboot format userdata && fastboot format cache

,then try to boot.

If it still fails, something else is corrupted at which point you can try what is suggested on this thread: https://xdaforums.com/t/lenovo-legion-duel-2-fastboot-stuck-fix.4393469/
[Lenovo Legion Phone Duel 2] &(*):
@kofijordan

Try using the persist.bin which can be changed to persist.img from: https://mega.nz/folder/TqxSjYrD#l3GM8SQgJcxhVrSeXMLW7Q and then,

fastboot flash persist persist.img

I went back and read the discussion here in the thread and you stated it has to be plugged in for it to even turn on. More than likely the hardware itself has been damaged and that could be the cause of all the trouble with it. By now something should of resolved the issue with the bootloader/boot loop we've been trying to work past. Instead of us flooding this thread, start a new one if you wish to continue testing solutions.
[Lenovo Legion Phone Duel 2] kofijordan:
the plug in issue is common with the crash devices i have seen on the lenovo forums. just the problem is the flashing part it seems like the legion 1 is easier to unbrick compared to the 2

the vmsystem partition seems to vanish when the phone bricks so it causes alot of problems. Im working with a tech to get mine repaired so if there is any progress or if its fixed ill make a thread to try too explain how its done for those with similar issues to mine
[Lenovo Legion Phone Duel 2] &(*):
You could dd the .bins from the link provided from @tinman4209333 . It contains the partitions necessary to boot the device. It would be a pretty straightforward procedure, as long as you didn't touch certain partitions; trying the vm-bootsys and super partition is where I would start. You would do it through adb shell with root permissions and simply dd if=partition_name.bin dd of=/dev/block/... .
[Lenovo Legion Phone Duel 2] Bilaljaved0:
It also happened to me
[Lenovo Legion Phone Duel 2] mitman93:
Currently experiencing exactly the same thing. What sucks is...I had finally gotten the bootloader unlocked and everything was working PERFECTLY until the ZUI 13 update ****ing LOCKED MY BOOTLOADER again. And flashing the sn.img wasn't unlocking it. So in an effort to unlock the bootloader again, it appears I've bricked the phone.

Have tried literally everything. For a while, I was at least able to access recovery + fastbootd. But now I'm stuck in EDL. No matter what I do the phone just reboots back into EDL. Think I've finally bricked it for good. RIP.
[Lenovo Legion Phone Duel 2] project_2501:
Try force shutting it down by holding power for 20-30 seconds. If it still boots into edl you can try rolling it back to an 11 build. Try firehose-lite protocol to see if the device responds, use QFIL and see if it registers an open COM port. Did you convert the region from a Duel 2 to a Pro 2? If you can get it to boot again I believe the SN.img requirement might not exist anymore (apparently doesn't for y70) just try "fastboot flashing unlock" after enabling oem unlocking if you can get your device to boot again with the most recent ZUI 13 build.

Hi everyone! I'm Josh, go by Sewdohe. I'm a web developer, that happens to really enjoy systems programming.

I'm currently in phone limbo, on my second Pixel 3 XL refurb from some Ebay seller....been 2 months of headache and irritating phones.

I've fallen back to my old Moto E (2020 Edition) and I absolutely hate it. It's so slow, I'm in the process of loading Lineage on it with no luck so far. Going back to stock to try again...cause why not?

This has really re-lit the fire that I had back in like, 2016 of how fun flashing phones really is. Tinkering, ehh? I'll for sure be flashing my Pixel 3 when I get all of this straight.

Thanks for the read, whoever read this! Wish me luck. Sim card isn't reading :(

[OnePlus 8T Questions & Answers] 1337haXXor:
I didn't realize until after I received it that the KB2000 was the Chinese variant. The one I bought said it was was GSM unlocked. I switched over to T-Mobile but have abysmal service where I'm at. The most I've seen from my house all the way to work (which is admittedly, in the boonies) is 1 bar, and most of the time it's just an "x." I had Sprint before which was pretty bad, but at least actually worked. I figured T-Mobile would be the best bet, as they're merging, but that was a failure.

Anyway, the listing says the phone is GSM unlocked and not for Sprint or Verizon, so is there no hope for getting this phone on one of the CDMA networks? I love the phone, but if I can't use it as a phone, I can't do much...

Dang, that's not great. Thanks a ton for the help! I've somehow never seen that site, I've been using willmyphonework.net, which is.. meh.
[OnePlus 8T Questions & Answers] Dopamin3:
It won't work on Verizon well (if at all) since it's missing band 13. So Verizon is out.

Theoretically it could work okay on T-Mobile since it supports bands 2/4/12 but "boonies" coverage for T-Mobile is trash in my experience. It's also lacking band 71 which travels furthest from the tower (realistically this probably won't make a difference if you already have super poor signal). Some phones on T-Mobile will get native Sprint signal now too- I noticed this behavior on my Pixel 3a XL but not on my OnePlus 8T KB2005. Certainly the KB2000 will only connnect to native T-Mobile. This is reserved for iPhones, Samsungs, Pixels I think.

AT&T might be worth a shot. It supports bands 2/4/5/17 and KB2000 is on AT&T approved device list https://www.att.com/idpassets/images/support/wireless/Devices-Working-on-ATT-Network.pdf 17 is the low band coverage (700MHz) just like Verizon B13 and T-Mobile B12. AT&T has better rural deployments too in my experience. It won't get 5G and you're missing bands 14,30,66 but 2/4/5/17 is enough to have a decent network experience.
[OnePlus 8T Questions & Answers] 1337haXXor:
First of all, wow, thanks a bunch for the help!

Yeah, I was trying to get *away from* the big guys like Samsung and Google. I've had LG phones for a while and liked them (don't care for updates, so it doesn't bother me), but now that's a no go..

Saved up for the nice OnePlus, and I know people have said they're kind of "selling out," but they're still super root friendly and very open, so I was excited. I also knew I wanted to switch to GSM (been on Boost/Sprint forever, now), and I figured going to T-Mobile from Sprint would be my best bet, as I figured I'd have T-Mobile's coverage PLUS Sprint's, because of the buyout.

Then I read Sprint users can all fallback on T-Mobile, but not the other way around? Except for your listed "premium" models. And I also didn't figure the "boonies" service would be quite this bad; it's awful.

Other people around me say ATT is awful as well, pretty much only Sprint and Verizon are serviceable. Looking at the frequencies, it has no Sprint CDMA bands and with Verizon it only has one: BC0 (no BC1). I've read that 13 is Verizon's "main" LTE band, but how do we know this information? Is BC0 (800) better than BC1 (1900)? I know that *overall* with Verizon the service wouldn't be fantastic, but as long as there's connection in the boonies, that all I need, really.

Running Android 12 on my Pixel 5 and Pixel 4a. Even on the 4a it's buttery smooth and I'm loving the new UI. The only bug I've had is that Twitter was acting buggy, but after reinstalling, all seems well.

I'd stay away from the OnePlus betas for now, as I hear it's bricking some devices.

[Xiaomi Mi 11 Ultra] RX1337:
Hey guys has anybody tried other xiaomi chargers with their mi 11 ultra?

Chargers like:

Xiaomi 65w Gan charger (USB c Port)

Xiaomi 65 w charger (USB a port)

Xiaomi 55w Charger

How well did these fare compared to the normal one(possibly with a adapter to actually use it)?
[Xiaomi Mi 11 Ultra] sabrewulf:
I use 65W Gan because i don't have one in the box.

Available in EU version, so it's perfect for me, and it's a small charger.
[Xiaomi Mi 11 Ultra] RX1337:
Did you check if it actually gives you about 65w?
[Xiaomi Mi 11 Ultra] achimmexico:
I use the 65 W Gan charger with USB C port from Xiaomi with my Mi 11Ultra. It supports turbo charging. It takes aprox 45 minutes from 10 - 100 %. I can highly recommend it because it is half of the size of the 67 W charger and almost the same charging speed.
[Xiaomi Mi 11 Ultra] RX1337:
I'm sorry if it sounds silly but did you check with apps like Accubattery how much voltage etc it gives? It should be possible to calculate the watts like that
[Xiaomi Mi 11 Ultra] Jhonxs:
Hello, i'm using the original 65W xiaomi gan charger Eu version. Model BHR4499GL

I'm very happy with it and accubattery indicates even 10mA charging current, depending on the battery temperature, system load and the charge level of the battery itself.

When the battery is empty ( or bellow 20% or so) it will go to max 10mA from what i've seen and of course drop to around 3-5 mA when it's nearing full capacity.

I never let the battery drop bellow 20% and usually try to unplug the charger until it reaches ~90% but rarely manage to do so because is damn fast :) .

If i wake up in the morning with around 30-40% charge i plug it in for around 10-15 minutes and it almost reaches 90% maybe even more

I also use a special PD 2.0 usb type C to type C cable from Baesus, model CATKLF-ALG1

"Baseus Type-C Cafule PD2.0 100W flash charging cable (20V 5A) 2m Black (CATKLF-ALG1)"

So it's not only the charger but also the cable that it's important

Take care !
[Xiaomi Mi 11 Ultra] Jhonxs:
Moreover, the Model BHR4499GL actually supports multiple charging standards than the 67W one that comes in the global unit's box . Plus it's type c so it's easier to find pd charging cables that will work with it
[Xiaomi Mi 11 Ultra] RX1337:
@achimmexico @Jhonxs @sabrewulf I calculated it. The 65w GaN Charger does about 38-39 Watt (i charged from about 10%)

Calculate it yourself if you like.

9810 mA

3.96 volt.
[Xiaomi Mi 11 Ultra] hgoor:
My 11 ultra charges fine with every generic quick charge 3 charger i have but of course better with the 67watt charger that came with it.

Didn't know it got sold without a charger?
[Xiaomi Mi 11 Ultra] Deleted member 5408779:
I have 65W and 67W charger and there is a difference about 2-3min when charging from 3% until 100%.
[Xiaomi Mi 11 Ultra] RX1337:
Yeah I noticed that too that the 65W charger doesnt take much longer. But yeah.
[Xiaomi Mi 11 Ultra] leoking3:
This is very strange to hear (read) , as I have a Mi11 Pro and of course use it with the 65W charger, but it takes 55 minutes to go to full. This is extremely frustrating, as 11 Pro should charge in about 36 minutes.
[Xiaomi Mi 11 Ultra] RX1337:
Honestly it always depends on the battery temperatures and all that. Also keep in mind that chargers always have inefficiencies as well. Sometimes the slow charging seems very random. I am using the 67W Charger for instance. Xiaomi's Charging Tech feels either inconsistent or it's just that the battery or charging brick may just are weird with charging them sometimes.
