Here is Mi 9se not Mi 9 section - sorry my fault!

2. Rom, kernels... not q&a or apps&mods.- You are wrong, it also says: "...other development"

3. Linked zip is for MiFlash with persist partition (sensors fix). Yes, works via MiFlashTool.

4. No internet - rather you have problem with router not with smartphone. - I am IT-Professional. The problem occurs in any other WLANs. In my WLAN, other phones have no problems.

You need to reflash full rom. I don't think that persist can help. If you want - unzip it & install via twrp or dd command. [MENTION=7091341]ChingghisKhan[/MENTION]

[Xiaomi Mi 9 SE Questions & Answers] ChingghisKhan:
Qoute from the thread you sent: " install/flash img at persist partition"

TWRP does not show the Persist partition - I have tried to mount it and it mounts in TWRP but still doesn't show when I try to flash persist.img

Then I tried from another thread https://xdaforums.com/mi-mix-2/help/mi-mix-2-sensors-expect-proximity-sensor-t3777015#post79961804 to copy new files into the "Sensors" folder.

You need to be rooted and have a root explorer

Backup your /persist folder

Download the attached zip file

Extract the zip

Paste all the 5 files from the zip to your phone in /persist/sensors/

Reboot

Let's see if this fixed Internet. The Proximity sensor is still not working, but that may be the hardware.My proximity sensor worked only 1 out of 30 times testing it, mostly after reboot or screen wake-up.

I will report back to you.

Thanks

EDIT: After replacing the files in the sensors folder, doing a complete wipe and re-flashing RevengeOS, the proximity sensor is working now.

I finally took this MI9 JUNK back and got me a OnePlus 7.

What REALLY got on my nerves is the fact that I can't ven use this bloody phone if I don't log-in to Xiaomi.

****ing bloody spies! That's one reason why I am not using an iPhone.

And all those bugs they ship with their original ROM - PLAIN REDICULOUS!!!

No support and the "Senior Moderator" only tells people: "I will report this to the developers...."

After two years, the issues still persist.

NEVER, NEVER, NEVER, ever will I buy a Xiaomi again, BASTA!

[LG V20 Questions & Answers] mickeyasamoah:
Hello! I plan getting an LG V20, yet i can't seem to determine which of the variants have the most support (As in custom roms, kernels, recoveries, unbrick, etc...).

My previous device, the V10 T-Mobile version had an unlocked bootloader but couldn't be flashed with a custom rom or downgraded due to LG enabling the QFuse or Anti-Rollback.

I am hoping to get myself a V20 variant that has the most support and also free from anti-rollbacks like my previous V10.
[LG V20 Questions & Answers] princedede:
Get and ATT. But it should be less than android 8.0 oreo or oreo 20g software version. Preferably on Android 7.0

TMobile one android 7.0 is also good. But I prefer h910 ATT
[LG V20 Questions & Answers] mickeyasamoah:
Thanks for the suggestion. Could you elaborate as to why i need to get a device that is less than android 8.0?

Back on my T-Mobile V10, the last official android version (MM) came with all the lock down that made it impossible to falsh the device.

Is it so with the V20s running Oreo?
[LG V20 Questions & Answers] ssnova:
Thanks for starting this thread, I was wondering too, especially regarding the T-Mobile and Verizon version as there seems to be plenty of them out there for a lesser price. I personally have an unlocked US996, but was thinking about picking up a ATT h910. The V20 is an amazing phone, what I'd consider one of the last "great phones" that had it all-hardware wise: removable battery, expandable memory, IR blaster, 3.5mm headphone jack, and an FM player.... in addition the Quad DAC and content creation features made it even sweeter (manual mode for the camera, very competent microphone). Though we all complained about LG's horrible software updates, in my book this phone is a beast and a legend, speaking hardware wise, they don't make 'em like this anymore...sadly so too..
[LG V20 Questions & Answers] mickeyasamoah:
The V20 seems like a great device...judging from my previous V10. It is the reason why i am choosing to get the V20 over the Xiaomi Note 7 or Xiaomi 7.

But i still need a bit of clarification as to what makes some V20 variants better than others and why i am required to get a variant with Nougat instead of Oreo.

I just wanna get a variant that isn't locked down like my V10 was. Any suggestions or explanations on the matter is very welcome.
[LG V20 Questions & Answers] ssnova:
I understand, and I'm on a similar boat, as my US996 is stock and I'd like to pick up another one to run LOS/community developed and I was wondering if there was a more preferable V20 variant over the other. Hopefully someone more acquainted with the subject matter can chime in.
[LG V20 Questions & Answers] princedede:
Yes it is. That's why it's better to have a V20 with Android 7. For ATT H910, android 8.0 on version g is still rootable. 8.0 version H, I can't say. So basically just get the one with Android 7.0 installed

---------- Post added at 11:56 AM ---------- Previous post was at 11:54 AM ----------

T-mobile, ATT V20 is okay. U can get any. But let it be on Android 7.0
[LG V20 Questions & Answers] mickeyasamoah:
Wow! Isn't the US996 supposed to be the Non-Branded version of the V20 which allows bootloader unlocks from the LG website?
[LG V20 Questions & Answers] mickeyasamoah:
Thanks for the clarification. But what of the US996 version which is supposed to be the version unlockable from the LG website? Does it also have to be on android 7.0 too or does it not matter what version it might be on?
[LG V20 Questions & Answers] C D:
Due to the official LG support, the version should not matter for the unlocked US996. The tricky part may be actually finding the correct phone as there are two other US996 variants that are not unlockable from the LG website. The unlocked one has "USA" written to the right of the barcode on the sticker behind the battery, as seen in a couple of photos in this thread. The other two US996 models have "UCL" and "BPT" written instead.

Of course, all of them can be rooted and have custom ROMs, but it's a lot easier to get there on the US996 USA.

Generally, I'd say the US996 USA alongside the H910 and H918 have the most custom ROM support around here. Not sure if it matters to you, but do note that all the US996 models have the FM radio disabled. And generally, getting a V20 already on Oreo is not a huge problem (except for the LS997 model where it's unrootable due to anti-rollback) since you can still downgrade to Nougat to do the TWRP installation/rooting procedure.
[LG V20 Questions & Answers] ssnova:
Thanks, this answers a lot. I was kind of confused because the other day I came across a thread about "cross flashing" V20's, from what I gather, you could flash a.. say H910 to US996, didn't delve too deep into it, but had me scratching my head, sounded like it almost didn't matter what version of V20 you got, you could do almost anything with it.

To the OP, yes the US996 is an unlocked US variant, but I'm gonna keep it stock for now.
[LG V20 Questions & Answers] mickeyasamoah:
Oh my word! Thank you so very much for this detailed explanation, This indeed answers 90% of my questions.

Since anti-rollback wasn't enabled on all the variants except that LS997 variant, getting a v20 on Oreo doesn't mean the end of modding for the device, as i can always downgrade to an Nougat and root the device. Right?

Oh...and if i read you correctly, All V20 models except for the US996 model have FM Radio functionality enabled.

I can't wait to get myself a V20 now as all my previous LG devices were T-Mobile branded and did not have FM Radio support.

It's great to know that FM radio works on even the T-Mobile variant of the V20.

Thanks again for the detailed clarification.
[LG V20 Questions & Answers] mickeyasamoah:
Rodger that!

With [MENTION=7601382]C D[/MENTION]'s detailed explanation, I might get the T-Mobile Variant of the V20 as the bootloader on T-Mobile variants of all my previous LG devices were really easy to unlock with the following fastboot command without any unlock code or unlock.bin file.

fastboot oem unlock

I just hope the bootloader unlock process is as straight forward on the V20 too.
[LG V20 Questions & Answers] C D:
You're correct about downgrading. In fact, if you look at whatever rooting guide you end up following, it will most likely involve downgrading to Nougat.

A few more bits of info:

- The T-Mobile H918 actually does have anti-rollback, too, but can still be rooted using a different procedure. You can still downgrade to a certain version number.

- Another model with the FM radio disabled is the Verizon VS995, but someone on here cross-flashed it with H910 firmware to get FM radio working and only had to flash the VS995 modem files to get it going. Same thing has been done to US996 models, but apparently, the front and back cameras get flipped as a side effect.

Only for the US996 USA, sadly. Most of the procedures for the other variants are quite unusual with plenty of steps, so read up carefully before you dive in. I have done it for two older LS997s while I also bought a used US996 USA and H918 that already came rooted.

Also, if you are going for the T-Mobile H918, absolutely make sure it is carrier SIM unlocked. As far as I'm aware, a locked H918 can only be unlocked if you are a current T-Mobile USA customer or via a paid service which can cost more than $80 USD (almost the price of a used V20). It's nothing like the simple unlock PIN codes you may have seen for other carriers.
[LG V20 Questions & Answers] mickeyasamoah:
Wow....If the T-Mobile variant does come with anti-rollback, then i guess i would have to refrain from it even tho it might be downgradeable to some extent. Anti-rollbacks are always up to no good. Downgrade too much and u risk blowing a Qfuse or something.

Moving forward....How is the AT&T variant? Does it have any anti-rollbacks? I would rather have a variant that has no anti-rollback even if it's rooting or unlocking guide might be much complicated as compared to the H918.
[LG V20 Questions & Answers] mickeyasamoah:
The anti-rollback on the H918 has really thrown me off. Else, the T-Mobile variants of all the LG devices i owned in the past were SIM unlocked. So that wouldn't have been an issue.
[LG V20 Questions & Answers] C D:
Only the H918 and LS997 have anti-rollback, so you'd be safe with the H910. However, both the LS997 and H910 (by now you probably realize how ridiculous LG has been with all these variations) have no official firmware (.kdz) files, so I'm not sure how difficult it would be to restore the phone in the unlikely scenario that you somehow lose TWRP recovery.

Look at the rooting guides specific to both H910 and H918 to see what you're up against and what pitfalls may lie ahead before you decide.
[LG V20 Questions & Answers] mickeyasamoah:
Oh My! These are some of the things LG does that made me say to myself in the past..."This would be my last LG device." But somehow, i keep finding myself crawling to LG.

Like you said, i have to read as to determine which variant's shortcomings is less damaging.

Before i go digging into V20 threads, is it possible the H910 has a tot even tho it doesn't have a kdz?
[LG V20 Questions & Answers] C D:
I have never seen any firmware files at all available for the H910, and other V20 variants have KDZs only, no TOT files.
[LG V20 Questions & Answers] mickeyasamoah:
Wow....LG really makes sure each variant lacks something. H918 has easy bootloader unlock but a dreadful anti-rollback, H910 has no rollback but has no firmware files.

I was just reading and i noticed that the anti-rollback on the H918 was introduced in the firmware version 10K.

Does this mean that an H918 with firmware version 10K and below would be fine? If yes, would a rooted H918 with 10K be able to flash custom Oreo ROMs?
[LG V20 Questions & Answers] C D:
I think anti-rollback (ARB1) started with 10P, but anyway, the newer rooting method works on all versions, even the older ones on ARB0. And I guess the only available stock-based H918 Oreo ROM, Alpha Omega Oreo, and the newer LineageOS versions, too, would have ARB1 when installed. So basically, if you plan on installing any of the newer ROMs, you'll probably end up with anti-rollback enabled on the H918. At this point, the only advantage I see with having ARB0 would be that you could still install older Nougat ROMs from before ARB1 existed. All the more recent ROMs should be compatible with the H918 on ARB1.
[LG V20 Questions & Answers] crumbling9999:
Its not really LG, blame US carriers and their love of sodomizing their customers. AT&T and Sprint explicitly chose not to release stock ROM, and Sprint/T-Mobile increment ARB. Manufacturer hands the base device to the carrier, and the carrier decide what security features they want to enable. It could be worse, American Samsung flagship are practically impenetrable, the S7 was only rooted because an engineering firmware was leaked, but it had serious performance issues and minor side effects. The Verizon Pixel is locked tight as well, as with Verizon phone in general historically.

But generally, the only model to avoid is LS997 because only a tiny number of them floating around are still rootable, and even rooted you're restricted as hell because you're stuck using the ancient ZV6 modem. H918 has a slightly more involved rooting process, but once you're done its set and forget. Anti Rollback is only ever an issue if you need to go back to a pre-ARB version to root, and with the H918 that's not the case.

S tier: F800/Korean. First in line for OTA, last to get support dropped.

A tier: US996 (free market). Official bootloader unlock

B tier: US996 (carrier), VS995, H910, H915. Fully flashable to US996 bloat-free firmware, can take US996 modem firmware without losing signal. Some people reported signal issues with crossflashing on the H910/H915, but it easily could just be user errors. The H915 has official KDZ, and the H910 can just flash a custom made return to stock package even if it doesn't have an official KDZ.

C tier: H918. Roundabout methods required compared to DirtySanta compatible models.

D tier: H910PR/etc.... Unpopular models from "literally who?" countries, dual SIM models. It might work, or it might not. Dual SIM model seems to have issues due to the hardware difference, and there's no dev with the actual phone.

E tier: Rootable LS997.

F tier: Unrootable LS997

As for the FM Radio thing, its enabled/disabled kernel side. A lot of people reported losing FM Radio after rooting and installing a custom kernel in the early days threads because its built from the US996 source tree. Its well known at this point that hardware/mobo wise all single SIM V20 are equal (refurbished American V20 popping up with F800 coded mobo), just a difference in software and eFuse pop. Hence some model can take cross flashed modem well, and some can't. It might actually be just software, because the V30 had an early Nougat firmware for the US998 that could be flashed onto any carrier device and modem would work fine. You can then upgrade from this version to any later firmware, and modem will still continue to work, even if straight flashing newer firmware doesn't.
[LG V20 Questions & Answers] mickeyasamoah:
Wow! Thank you very much! This is lots of information.

I was down to the H918 (T-Mo) and the H910 (AT&T). And since the H918 had the anti-rollback, i was a little skeptical as i would love to be able to try out Nougat ROMs as well as Oreo ROMs and even Pie ROMs should they be available.

Now that it's being made clear that the H910 (AT&T) has no anti-rollback and is likely to be flashed with the US996 firmware makes it the best variant of the V20 for modding.

I guess I can confidently say i would be going in for the H910 now.

Only things i wanna clarify are:

Is the US996 firmware which you made mention of a KDZ which can be flashed from download mode?

I am just making sure that there's a KDZ rescue for the H910 in case of a brick. (loss of system and TWRP)

Does the H910 have lot's of custom ROMs spanning from Nougat up to Oreo?

I know for a fact that with the H918s, you are either able to flash Nougat ROMs which i understand have the ARB 0 or the Oreo ROMs which seem to have the ARB 1. In other words, it's once you go Oreo u never go back with the H918s.

Yet since all H910s have no anti-rollback, I understand it should be able to flash Nougat and Oreo ROMs with ease.
[LG V20 Questions & Answers] mickeyasamoah:
Thank you [MENTION=7601382]C D[/MENTION]. You have been really helpful with clearing up things regarding the V20's variants for me and everyone else.

The H910 seems more promising and the best option as it is possible to flash it with the US996 stock firmware in addition to it having no anti-rollbacks.

The only thing i want know is if the US996 firmware which can be cross flashed onto the H910 is indeed a KDZ.

If the firmware turns out to be a KDZ, it would mean in the unlikely event where TWRP and System is inaccessible, the device would be unbrickable by flashing the US996 firmware via download mode.
[LG V20 Questions & Answers] C D:
As far as I'm aware, all cross-flashing on the V20s are done through KDZs. (As an aside: H918 KDZs are only compatible with the H918 and will permanently brick any other model while an H918 can only accept H918 KDZs and will get bricked by any other model's KDZ. You may see huge warnings mentioning this in ROM threads.)

From what I've seen, people have cross-flashed the H910 with either H915 or US996 firmwares in the past. If you stick with US996 throughout the rooting process and don't want to return to H910 firmware (remember, it has FM radio while US996 does not), then I think you'll need to assume it's a "Dirty Santa" US996 (like UCL and BPT) and not an unlocked USA one. Some ROMs have different files to distinguish the US996 models.

And I'd say that the H910 has pretty much the same ROM support as the other rootable U.S. variants (H918, US996, VS995).
[LG V20 Questions & Answers] princedede:
Hey bro. Just get yourself an H910. I use H910. Rooting following the steps accurately isn't dat difficult. And yes, H910 takes unlocked us996 and H915 kdz should u run into any problem which can be flashed via download mode using modified lgup. And all the available custom ROMs is available for H910.. personally this is my 3rd H910 device cos i do sell them and i am enjoying every bit of it.

Just get one of it then let us know what u have got. And the android version that comes with it so as to lead u on rooting. It isn't really that difficult...

But please get an unlocked version. Thanks
[LG V20 Questions & Answers] mickeyasamoah:
Thank you, I am definitely getting the AT&T variant (H910).

And by "get an unlocked version", I presume u were referring to a SIM Unlocked version and not a bootloader unlocked version as the H910 doesn't have an unlockable bootloader.
[LG V20 Questions & Answers] crumbling9999:
All V20 are/can be unlocked by flashing to a non-locked variant's firmware.

>Is the US996 firmware which you made mention of a KDZ which can be flashed from download mode?

Yes

>Does the H910 have lot's of custom ROMs spanning from Nougat up to Oreo?

No. Well, the entire V20 line effectively has 1 custom ROM - LineageOS. ResurrectionRemix is built from the LOS device tree and has the exact same bugs. Everything else is just out of date stock ROM with a coat of paint and a large helping of snakeoil. You're always better off just getting whatever the latest stock OS is and debloat/modify it to your need in these cases.
[LG V20 Questions & Answers] mickeyasamoah:
Mmmm...this is just music to my ears. I guess i have no doubts about going for the H910 now.

I have a couple of follow up questions if you don't mind.

After an H910 has been crossed flashed to with US996 or H915 firmware, Is it possible to revert back to H910 firmware since there aren't any H910 KDZs?

Not that it really matters or anything, but just wanted to know.

By unlock, did u mean bootloader unlock or SIM unlock?
[LG V20 Questions & Answers] crumbling9999:
> Is it possible to revert back to H910 firmware since there aren't any H910 KDZs?

Yes, people has made TWRP flashable package containing the full stock dump from a newly updated device. And SIM Unlock. VS995 are fine as well.
[LG V20 Questions & Answers] princedede:
Yeah. Network unlocked

---------- Post added at 12:35 PM ---------- Previous post was at 12:29 PM ----------

If u are using an h910 with a newer firmware for example. For u to unlock bootloader and root. U will need to flash a kdz of an older firmware of h915. Can't remember the version but it's on the root thread for h910. After flashing the firmware. Then the next step is to flash a custom recovery and root. After rooting and recovery installed u can then flash an h910 rom.

This is simple. Get an h910 device the steps to root is available on here.... U worry too much i think.
[LG V20 Questions & Answers] mickeyasamoah:
Yes Sir.... No more worrying.

I hope to get the device by the end of this week.
[LG V20 Questions & Answers] mickeyasamoah:
It's Here!!!!

I got an H910 running Nougat, I think. I am not sure which build of Nougat tho (I would send a screenshot soon.)

I am charging it at the moment.

Everything seemed to work. The only weird thing was when i typed "adb reboot bootloader", it just rebooted back to android.

Also when i inserted an SD Card, it kept booting into download mode even tho i had no USB connected until i cleaned the connectors on the SD Card.

Don't know if that was normal.
