Hi All,
I hope I am asking in the right area and forgive me if I havent.
I have a Mi Mix 128gb running Niui Global 8.0 Stable 8.0.7.0.0 MAHCNDI which I believe is a vendor rom? I try to go into updates as I see on the MIUI website there is a version 8.0.10.0. and I would like to update to that.
-I tried the update button where it takes a few seconds saying checking and comes back with no updates available.
-I then tried the choose update package in the update app and chose the rom I moved onto the phone (not in a folder as specified) and it says getting info and then comes back 'couldnt verify update package'.
-I then tried the reboot to recovery mode and named the rom 'update.zip' as specified and all I got when I tried to enter reboot to recovery mode from the actual update app was a black screen wth a phone and a cord plugged in and a website address, no graphical selection tool where I was able to select using volume up and down etc.
I had read somewhere it could be due to the fact that when the vendor flashed the global rom they may have left the bootloader unlocked and that is why the phone isnt finding the update or running it from the file on the phone.
Does this make any sense or am I just missing everything and doing something wrong?
If it is the unlocked can I lock it again to so that I am able to update.
I did try the other thread on verifying the bootloader and how to type in the command to relock it but I wasnt able to use the ADB as I am not all together familiar on how to use it.
If anyone out there can give me a hand I would be forever grateful and I would ask that if you can help that it be as detailed as possible as I need all the help I can get
Thanks so much in advance
Dis you get your Mi Mix from a vendor who loaded Gapps for you? I think that 8.0.7.0.0 is a vendor ROM, not the CN Stable or EU Stable ROM.
I suggest you find the ROM guideline thread here and update to the CN or EU Stable ROM
Best

It is definitely a vendor rom. To begin with, this phone has no Official Global rom yet. It states it is a global rom but in the Rom name it contains the letter CN, which identifies the rom as the chinese rom. Therefor yes, it is a vendor rom.
I don't have the phone yet so take my advice with a grain of salt, but i'm pretty sure that an unlocked bootloader does not interfere with installing roms/getting ota updates etc. Sorry, with an unlocked bootloader you can't get OTA updates. But you've got a vendor rom so you wouldn't be able to get one in the first place even with a locked bootloader.
I think that if your bootloader is really unlocked, the fastest and easiest way to flash the newest rom would be by using the MiFlash program from Xiaomi. Here's a guide for that:

(Method 3, Step 2)
Let me know if you managed to flash it.

Thanks very much for help. I managed to flash it to the official Chinese rom but now things like the proximity sensor isnt working and a few other things. Still cant get the google movies to download or play either so I will try your guide....will let you know how it goes.
Thanks again!

If by "google movies" you're referring to movies downloaded from google play, then make sure you disable download manager in the Miui appstore settings. It connects to a chinese proxy and therefor is buggy and really slow.
Thanks to everyone on this forum as I now have a EU rom running on my mix and everything is working. I can download and watch movies from Google Play, I can watch and download Netflix and Google Contacts (the app not sync) now installs and works. Now this is the phone I wanted it to be and I am thrilled.
Thanks again

And you shouldn't have any issues.
Did your phone come with the Global 8.0 Stable 8.0.7.0.0 MAHCNDI s that is what mine started with and the only issue was that I had to use the ADL mode to get the phone to recognize and take the TWRP so I could get the EU rom working. Been using it for a few days now and no issues whatsoever. Good luck!
So, I have an Honor 5C (I’m in Europe, if that’s significant), I’ve been rooted for a while and today I wanted to install a custom ROM. After installing TWRP using the official app, (I tried it with fastboot, but no success) I downloaded the LineageOS 14.1 ROM and tried to install it. This failed, I got error 7 and started googling the cause. No success. Right now I’m just confused with all the different 5C models and apparently different EMUI versions. My questions:
1. How do I know what model I have? (NEM-L21, NEM-L22, NEM-L51 etc.)
2. What’s up with the EMUI versions? I know I had 4.1.2 and never got a notice saying I could update to 5.x, so how are people on those versions?
3. Same for the Android version, I was on marshmallow 6.0 but other people are on nougat?
4. I wiped everything and am unable to boot right now. What ROM must I download to boot again? And is it possible for this to be nougat, instead of marshmallow which I was previously on?
Thanks in advance, I’m very new to this scene and all the different models and versions are kind of overwhelming me
First of all, you shouldn't use the official twrp, because that once partially bricked my phone, and you should have used EliteTWRP for installing the roms, because it required you to back up before some partitions, that official twrp couldn't, also, to answer your first question, you find it out in your phone's settings app, in the About Phone section, but since you didnt look at that before you flashed and deleted everything, I don't know how to figure it out without the settings app, also diffirent region phones get diffirent updates, my dad's honor 6 never got an update out of 4.4.2, but some phones had access to newer versions(not by flashing custom roms), also you should download some dload things i dont remember how to do it, never done that myself, but for that I'm pretty sure you need to know if you're using NEM-L21, NEM-L22, NEM-L51 or something like that
I got the T-mobile REVVLRY+ today, and naturally, I wanted to put the stock motorolla firmware on it. Partly to see if I could, partly to get rid of the T-Mobile bloat and see what Motorola features T-Mobile had removed.
Everything went swimmingly, I have PPW29.98-107 installed, I even have WIFI Calling. What I did lose, however, is VoLTE. I did use TWRP to perform a backup before flashing, so I tried restoring it to get a better look at how VoLTE works in the T-Mobile firmware. This is where things got hairy. I stupidly only backed up boot, system, and data. When I use TWRP to restore them, I get stuck in a boot loop. The built in boot loop fix in TWRP didn't help.
1. Any ideas on getting as close to stock as I can with only the boot, system, and data partitions?
2. Does anyone have access to a REVVLRY+ that would be willing to do a full backup that I may try to restore?
*Edit* SO I used the code *#*#4636#*#* and VoLTE provisioned is enabled, so maybe I do have VoLTE?
*Edit 2* Google Pay doesn't work, even after locking the bootloader. The device says that the operating system has been modified. Still trying to get it to restore.
FOUND IT!
I found a repo of firmware that has the TMO firmware! flashing now!
I can't share the external link yet.

Where did you find it at? I would like to know because I'm trying to port Lineage OS to this phone. However, once I unlock the bootloader, I won't have an OS to use for it and i'll be screwed.

HOW to
Hi, I just picked up the Revvlry+. Do you have step by step to install the Stock Moto firmware? I miss some of the features of the Moto. Also, was it easy to restore the TMO firmware just in case?
did you make any progress into the volte research? im on a unlocked xt1965-2 and using metro but i dont get volte in any of the stock roms or custom roms. i have tried flashing the modem from the stock tmo rom which didnt really do anything. i will probably try to flash the entire tmo rom tonight and see if it boots. im thinking if i get volte in the tmo rom and backup the persist, vendor and efs. then if i restore them onto a working cutom rom with volte enabled, volte should work.
i have also read about different scenarios in where you have to install workarounds to enable volte on treble roms. like installing the ims.apk to route the calls to volte and flashing a volte enabler to inject the correct files into the vendor partition.
my other device is a moto g5 plus which has numerous volte issues when switching between stock and custom roms or between different versions of android.
Did you use the Moto G7 Plus TWRP? I just picked up a Revvlry+ and I'm looking to root to install lawnchair or pixel launcher as a system app.
successfully unlocked the bootloader of my t-mobile revvlry which is a rebranded moto g7 i did it using this method but i'm going to be a little cautious on rooting unless i know it's safe and won't brick i could use some help with this https://www.androidinfotech.com/root-moto-g7-plus-pie/ i have the revvlry not the plus i want to try multirom installer and install ubuntu touch on it but i don't want to screw up my only phone but the only way i can try it is if i had root permissions to do so to install linux tried userland but i couldn't get unity desktop to work i'd rather have full root instead of fakeroot update: i was able to boot twrp before but now it doesn't work i think my firmware updated cause now when i run fastboot boot twrp.img nothing happens and i end up with remote failed reboot the phone and it goes directly to recovery with the only option is to do a factory reset

Are you saying with a Tmobile Revvlry, you were able to just go to the Motorola bootloader unlock page, paste your unlock codes, and presto as if it was just a normal Moto phone? If so, that is awesome!
I am thinking of swapping my Moto G7 Play with a Revvlry because of the 3gb RAM and NFC (the size of the G7 Play is perfect, I don't want to be forced to carry around a giant phone), but would love to flash the stock Moto G7 Play ROM over the Tmobile version. Not sure I'm willing to risk it, but if anyone has tried, I'd love to hear about it.
Logged into my account for this. Sorry if this is a little offtopic, but I want to see if this phone is compatible(or rather, how compatible it is) not only with Stock ROMs, but also with custom ROMs. For those REVVLRY owners, what have been your experience with this?

Phone works great with stock ROMs. I haven't tested out any custom ROMs, but I do have root on my REVVLRY.

Can confirm flashing Moto g7 play firmware on T-Mobile revvlry. Caveat, you can no longer take OTA's and NFC is broken. Also can be bootloader unlocked through the Moto website.
Wouldn't you need to flash the G7 plus firmware for NFC to work?

That makes sense, the SD632 is NFC capable however I'm on the G7 play not the plus (I know, I know wrong forum)
I can't get the stock rom to work. It just bootloops every time. I tried all 3 versions. Any ideas?
Hey friends, would one of you kind sould who own the Revvlry+ be kind enough to post this Wallpaper?
Thanks in advance!

Hello. I have a (locked) P Smart (FIG-LX1) that came with Android Oreo. It was a good device until it was updated to Pie. Even after the latest security update the phone is still a lot slower than when it was running Oreo, althout a bit better that the fist release (it looked more like a beta than a final release).
The point is that Huawei doesn't provide unlocking codes anymore, what is ridiculous, but being a Chinese company probably there isn't much we can do about it.
I know it is possible to unlock if the phone is downgraded and then using a paid solution, but it's it not an easy solution and not many people is willing to pay or can do it for many reasons...
I don't have any experience with Huawei/Kirin devices but other platforms like Samsung or Qualcomm have softwares that allow flashing while device is in download/EDL mode. This would make possible to flash stock firmware when the device is bricked. Using these tools it is possible to root and/or install a signed TWRP even if the bootloader isn't unlocked, so maybe there is a similar solution for P Smart.
Maybe it's possible using eRecovery? Is it possible to use it to flash unsigned data to the phone?
Any thoughts or info will be appreciated. Thanks.
Update: so far, I have found only two options that seem to work with Huawei phones that use HiSilicon/Kirin processors:
1. Some obscure IDT/Firmware writer that require enter "test mode" (it is normally done by shorting some test pads in the phone's main board), and they may not work with P Smart;
2. DC Phoenix claims to flash files while phone is in fastboot mode even with a locked bootloader, so this could be used to flash a signed TWRP to the phone and then proceed with rooting, etc, but it is also requires a payment for working.
All phones have some "unbrick" tools that work like DC Phoenix and allows flashing firmware in an emergency, and if DC Phoenix works with a simple USB cable and fastboot then there must be a way to flash a signed recovery to P Smart without needing to unlock the bootloader...
I reckon that the easiest solution is using HiSuite to rollback it to EMUI 8.0 (it gives version 8.0.0.176 for my FIG-LX1) and then using DC unlocker. However; it needs to be Windows app since macOS version does not have this feature.
It would be nice to have alternative, though. Did you manage to find any working examples of option 1 and 2?
Yes, the simplest solution so far to unlock is downgrade + DC Unlocker, but it is paid, and unlocking ins't actually needed for TWRP (and therefore rooting).
My phone is still locked and running latest firmware, but for my surprise it got a lot snappier after I did a full backup using HiSuite (I think it reset some settings and app permissions in the proccess). <<< GOOD TIP
Anyway, these are the sites with info about the procedures in my previous post:
1. Huawei IDT flash software - https://co.easy-firmware.com/how-to-flashing-huawei-board-software/
2. DC Phoenix related
Unbrick Huawei phones - https://forum.xda-developers.com/9-lite/how-to/guide-unlock-frp-phone-bootlooping-t3808650
DC Phoenix Huawei unbrick tutorial - https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
DC Phoneix Huawei flash tutotial - https://www.dc-unlocker.com/huawei-phone-flashing-in-fastboot
Again, if it possible to flash "unverified" (i.e. non Huawei signed) images then it is possible to flahs a signed TWRP to recovery or eRecovery ramdisk partition.

Wow ... before backup free RAM was ~1 GB, now it says 1.5-1.8 GB (like Oreo did?).
I'm looking for a good source of firmwares, i know the famous sites but some firmwares doesn't seem to be listed. I know in the time os Samsung KIES there were tools which communicated directly with samsung.
For example these firmware builds for the SM-G975Ux aren't listed on most firmware sites but have the December secutiry update with binary/bootloader version 8: G975USQS8IVL1 and G975USQS8IVL2
All the big sites have ROMs for that phone (same one I have). There is no "Ux" model... it's *U or *U1, with the latter being unlocked. IF you search for U1 ROMs you have many selections, but most get the XAA version which will usually change carriers automatically based on the SIM card.
The latest BL=8 version I see there is https://www.sammobile.com/samsung/g...M-G975U1/XAA/download/G975U1UEU8IWB6/1741280/ which is the February 2023 security update. I believe this is the last one we are getting (but I could be mistaken as there may be 1 more security patch, I don't remember).
There's U U1 0 W F N .... I'm looking for the oldest firmware with binary version 8, but it seems the sites don't show all firmwares available.... i'm looking for the oldest firmware with U8 bootloader (or any compatible bootloader with binary 8 version), i could have a look at all sites and try my luck... but they don't seem to have all data. but like i said i prefer some original source xml files... i saw some url's to original samsung servers but can't find them anymore.
There is already a firmware available with the march update.... but you have to be lucky to find them... i'm looking for original sources. like update.zip's and such
Found the first one....

You know how to flash lineageos through twrp right? and how to use odin?
Maybe flash lineageos to see if everything works.... and then revert to original software. Be sure to wipe cache/dalvik and userdata

Yes, I know there are many other variant firmwares out there, but for a U phone (snapdragon) there is really only U and U1... the rest are incompatible.
There is no "older" firmware with binary 8, because the firmwares are packaged with the proper/compatible binary already. Basically, the "binary" is the bootloader version. On Snapdragon phones, you must have the proper BL/binary to flash, as you already know. You can't interchange the binary/BL with the ROM and security updates because they are not made that way.
The update.zip you're looking for are updates sent by Samsung directly, and they can update the ROM (and Binary) from one stock version to another... but, again, they will update both the binary/BL as well as the ROM, so they can't be broken up to only do one or the other.
It sounds like you're trying to get to an older ROM version (for whatever reason) with an older security patch level as well? Basically, this cannot be done on Snapdragon phones. Once you're on an updated binary/BL, you're stuck there (at least today you are).

I've tried different firmwares, its all about snapdragon. You can also flash SM-G975W parts and other snapdragon variants.... there's a lot of variants out there.
I first upgraded and then downgraded to the parts i wanted and am on a rom now with security patch level December 2022, as long as the binary version is the same there's no problem. I've got the latest modem installed and the oldest firmare and bootloader for the latest binary version, i can upgrade or downgrade my bootloader. I already asked someone before if this was possible and if he could confirm because before i was only able to flash CSC and AP i think.
If there's no updates comming anymore why not downgrade and wait for a new leak
I'm also sure we can unlock the bootloader, i'm trying to make an lposed module. I've installed lspatch and lposed and they work fine for some modules. The bootloader unlock has several prerequisites (properties and such) if i can make it look for other properties or something like that we might get an unlock option. Also it looks for an encrypted file on EFS, if someone with an unlocked samsung phone could copy that file we would be a lot further.
It's called /efs/sec_efs/sktdm_mem/encmembership.txt and should be an encrypted file, also if anyone knows how to set ro properties without root (like a stub before the preference controller starts) this would be very usefull.
