[Solved]Requesting Help Regarding Mi A2 Lite (Stuck in Unlocked Boot loop, No OS installed) - Xiaomi Mi A2 Lite Questions & Answers

Just this day, November 23, 2021, I have been trying to flash a custom rom named Syberia OS for daisy(Mi A2 Lite variant). As I have done booting up the device to fastboot(thru cmd command since my power button is jammed), I installed the twrp after booting the image to the device, making it as my recovery.
Now I am set and excited to install the rom, so I went to fastboot again and tried to flash the rom, but it always errors and not installing the rom. It is said "to flash multiple zips, reboot recovery before..." (correct me if I'm wrong), so I rebooted to recovery thru the twrp (since its in fastboot). Now, I did the same, I installed the rom again and experienced the same error so I dont know what to do, I did wiped system, data, dalvik and internal storage (a lot of times and tried to install the rom again), but I get the same error.
Then since I cant install the rom, I went to reboot to system thru twrp, and then I forgot, that I have no OS installed.
So now I'm stuck with the "Your device software can't be checked for corruption. Please lock the bootloader. Please visit this link..." plus arriving to the AndroidOne logo, and it turns off and turns on again with the message and logo, repeats until the battery is completely empty.
Is there anything I could do to go to fastboot again for a clean install of the stock rom? (I promise to not unlock the bootloader and experiment on custom roms again)
(I am sorry if you find it hard to understand, I am willing to edit this thread for better understanding if there are things you dont understand.)

Hey brother, I had the same situation a few months ago. My device - Redmi 6 (Cereus).
So, I was trying to install TWRP in Redmi 6 and then after trying many times TWRP successfully got installed. But when I tried to boot the device, It stuck in bootloop (Going to fastboot and again booting...). So, the answer is that you first boot into fastboot mode of your device and then download the fastboot Rom of your device, (link of fastboot rom of your device - https://xiaomifirmware.com/download/18010/ ) . Then go to your PC and then extrac
the fastboot file, then connect your phone to pc and go to fastboot mode then open the extracted folder and then click on flash-all (The batch file) and then a new command window will open automatically and flashing process will start. After it's done your phone will reboot automatically. For reference, go ahead. Best of luck!

Oppo Find 7 Stuck at logo
I have not done anything to my phone at all. 2 days ago it started turning itself off and back on again, yesterday it did the same and now it is stuck on the Oppo Logo, it will not go any further. Tried turning it off and on again loads of times. Taken the battery out several times; Took the battery out and left it overnight; no success. Tried charging it to see if this would induce it to do something but not even the blue pulsing light is coming on. Apart from the Oppo logo it is dead......... Please, anyone any ideas, if you do then simple or step by step instructions..... Here is hoping, Thanks
PS....also tried taking simcard and memory card out and booting....same result also tried taking battery out and connecting it to the power supply, it goes into a recycle boot loop. I tried putting everything back in again and powering up but holding the power button down, again it goes into a recycle boot loop
PPS... Does not register on laptop when connected via usb
Somebody must know something.... Oppo again will not reply to emails.
I have scoured the forum and googled, as a result I tried the fastboot option using the recovery installer provided by xda. Recovery failed and when I tried to reinstall as a second option my laptop cannot connect to the phone, it just hangs on "connecting to your phone"

Yes the Programm works fine on a find 7a.

Probably not the thread to ask, but it is Recovery related:
I'm testing PA 4.6b6, but I would like to go back to ColorOS.
Will loading ColorOS rewrite my TWRP recovery and bring back stock Recovery?

Flash one of the ColorOS custom ROMs that the devs have created. There should also be a flashable stock version that removes the overwrite of Recovery. Just search around.

If u still want this tool he going yo reupload.
HI
Can you update the installer for the stock because your link is dead. i need to recover my stock os.thanks
Your link does not work any more
It says that the google drive file has been deleted
Will installing this recovery include the Google apps and the english version??? My oppo has the chinese OS and no Google play store that's why I'm asking
Unable to download recovery
Hi,
Do you mind to update the recovery installer? i not able to download the recovery here. Thanks.
I have strange difficulties installing the custom recovery to Oppo.
I have rooted about a dozen of different Android phones previously, so I thought that this one was a piece of cake as well.
I have tried to use this tool as well the "manual" method.
-I have installed the drivers correctly. Both ADB and fastboot do recognize the device.
-I have unlocked the device (fastboot oem unlock)
-I can reboot the phone to the fastboot mode and I have succesfully uploaded the recovery-image to the phone. I have tried both CWM and TWRP -recoveries and both of them will install nicely (fastboot flash recovery xxxxx.img)
So I was thinking that does the phone somehow overwrite the recovery that I have just installed? What is correct way to proceed after the recovery has been installed? Swith off the phone and restart the phone into recovery straight away? (Power & Volume down)?
Didn`t work for me because phone just ends up to the boot loop. If I will boot the phone normally, it will start all the way to the OS.
Device is
OPPO Find 7a
X9006
Android 4.3
ColorOS V1.2.4i
Build number: X9006_12_140712
Any ideas..?

Twrp keeps booting into the recovery

Hi there,
To make a long story short, CyanogenMod ****ed my rom when I updated it to a newer version and in return I decided to switch to another rom. I found one, it needed a "new" recovery (TWRP). Now I'm not new in flashing recovery's or rom's, done it on a few phones in my life, including my own about 50 times before. Everything goes correctly, TWRP got flashed, no issues whatsoever. I flash the rom and gapps, everything goes smooth and I reboot my phone. Now as I reboot, the htc logo pops up, then fades a little and comes back, it does this 3 times. Then it just boots into TWRP again. So basically it keeps booting the recovery.
Now I do my research and find this solution where you put in this line into the cmd, dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota. If I do this, and I typed it over 20 times now already, and i did it correctly, it says no such file or directory. I also tried it through fastboot on my PC, says the same thing. In return I can't get TWRP to just simply boot my rom. I browsed for over 2 hours now to find a fix, and the only thing people say is: you didn't type it correctly.
I think the boot order of the device is wrong and the recovery is on top, now I want my rom to be on top so when I reboot it, it loads it. I'm not an expert in all of this, I just follow guides and understand the basics. What can I do next to solve this issue? Flash TWRP again? Flash a different version of TWRP? I used "twrp2853", the one they linked to in the page of the rom. the rom is resurrection-remix-lp-v5-2-5-t2987006. I doubt it is the rom tho.
Thank you in advance,
MiniMi

Try this:
On your pc, unpack your rom zip. Then put the boot.img file into fastboot folder. Then boot into fastboot and type (ONLY IF YOU ARE BL UNLOCKED): fastboot flash boot boot.img . This is needed to boot the rom, because only flashing the rom doesn't boot them, due to S-ON. You need to flash boot manually. Follow the process and tell me the result

Stuck on team win recovery project please help

I have no idea how to root or anything like that, I bought this oneplus 3 and had a update a week later.. so when I did the software update it took me into teamwin recovery mode and now I don't know how to get back into my phone please help....
Did you buy the phone second hand or did you try to flash TWRP yourself? It shouldn't have TWRP installed by default.
Regardless, you can use TWRP to flash the latest update.
Given that you have TWRP, I'm assuming that you have an unlocked bootloader. Did you notice a warning pop up everytime you reboot your phone before? It should say something along the lines of "your device has been unlocked and can't be trusted". If not, you'll have to unlock it (it wipes your phone in the process).
If the bootloader is unlocked, you can simply download and flash the latest zip for OOS 4.0.3 in TWRP. This will update you phone and replace TWRP with the stock recovery (so you don't run into this problem again in the future when installing an OTA). If you don't intend to modify your phone in any way, then this is all you need to do, your phone should be functional.
There are plenty of threads with detailed guides on how to do all of this.
I'm also stuck on TWRP after stupidly downloading the latest OTA and I don't know what to do!
Phone won't boot normal, just goes off.
Situation:
- Bootloader, Fastboot and TWRP wil load.
- Device seen by windows
- Zip install in TWRP gets stuck at 'patching zip unconditiontally'
- Another zip flashes, but gets stuck at the end, no reboot option (manually but that's not the way)
Can someone please point me in the right direction? I don't care if I lose data, just want my phone back!
not helping:
Saying i'm a dipsh-t I know, I know, I will do better in the future, for now, help a brother out please

Simple, check the OnePlus D/L sites for this one http://oxygenos.oneplus.net.s3.amazonaws.com/recovery_op3.img and flash it by TWRP or fastboot to RECOVERY. Boot once with the official Recovery and all ist fine again.
This is issue of using a faulty twrp so for that when ur phone us booting up go to fastboot and flash twrp 3.0.4-1 and everything will work

Similar Problem here:
just wanted to flash latest OOS 4.0.3, so I flashed back stock recovery with flashify and rebooted into recovery mode to flash the already downloaded OOS 4.0.3. zip. That's when it began to go poop! After rebooting it just went dark with no Chance to power it on again! No dice with power button, Volume up/down + power button, nothing! Not even the LED's are blinking when plugged in. So this one seems to be basically dead!
I got it once booting again after randomly pushing the buttons (after x minutes!?), but everytime I reboot the phone it just shuts off without beeing able to power it on again. At the Moment it's dead!
Any ideas what might happened? If I get it on again, should I immediately reset it to factory Settings?
I am kinda lost here! Any help/ideas would be much appreciated!
Flashify? Never used it and never trusted apps which flash stuff on a running system. Use fastboot and reflash the recovery partition. Link to recovery is in my former post.
fastboot flash recovery PATHTOIMGFILE
Thank you for your advice! Still a lot to learn! Got it up again, will try as you suggested!
It appeared that my stock recovery file was corrupted , but all is fine again! Thank you very much!

I may have been the person you traded with to get the OnePlus 3, but I took the phone back and after 5 hours I got it up and running.
The phone would boot to TWRP, but even after wiping the entire system and dragging a ROM zip to the internal storage, reinstalling did nothing. It just kept booting back to recovery.
The solution entailed the following.
Download stock recovery IMG. Flashed through TWRP. Rebooted recovery and now was back to stock recovery.
Download the official OxygenOS ROM zip from the OnePlus website and changed the name to update.zip
Next I downloaded Android studio for access to ADB. I had never used ADB before, but I knew this was needed to push a file to the phone.
Needless to say, ADB kept freezing my computer when I would type in the commands to side load.
I deleted Android studio and installed a minimal ADB/Fastboot I found online. I opened my command prompt, typed the command for sideloading, and immediately got my installation starting. It took about 10 minutes to fully install. When it was finished, I rebooted and had a fully functioning OnePlus 3

LG G4 H815 No TWRP Access

Hello members of XDA,
The issue I'm having is pretty rare and found few or non threads about it, so I will try to be the most precise possible.
Yesterday I decided to change the ROM of my LG G4 H815, I was previously on LineageOS, since LineageOS on H815 wasn't developped anymore. So I asked myself why not trying Android Oreo with CypherOS. Before any changes I was with the latest version of LineageOS for H815 and I had TWRP with the version 3.0.2.1. Bootloader was obviously unlocked.
So I starded to download all the required material to switch to CypherOS 5.3.1, while the download I've made a backup of my actual lineageOS installation on my internal storage. Once every thing was downloaded I tried to install CypherOS I had an error 7 in TWRP install box, so I was pretty worried, scouted XDA threads about the error but i was redirected to the solution where you modify the update binary with txt but still didnt worked. I've found a thread talking about updating firmware of the H815 ( https://forum.xda-developers.com/g4/development/v5-8-5-n7-1-2-resurrection-remix-t3704450) While panicking I've done a wipe of everything (dalvik, data,cache and system) .I applied thge firmware update but I also re-read the thread of CypherOS and figured that I needed a newer version of TWRP, installed it so. THen magically CypherOS installed without any issue.
After installing the Gapps (Arm64 8.1 Nano) I rebooted and the first weird thing appears, after seeing the LG screen while the boot I have another screen telling me that the bootloader has been locked and that i should visit g.co/ABH for more information, then CypherOS initialise, CypherOS worked like a charm. So I wanted to go to my TWRP and make a backup in case. I launched ADB and use the command adb reboot recovery, the phone restarted and had the following events : LG logo, warning message about the bootloader, LG logo again and then a black screen. However I was in recovery mode since adb found me with the command fastboot devices. I had no TWRP logo or anything linked to it. Few minutes later, I had the basic recovery mode where you move yourself with the volume buttons and select with power where the functions are pretty limited.
Then I rebooted the phone with adb (fastboot reboot), CypherOS still working perfectly. Thaught that it was the bootloader which back to scratch when he was blocked, I figured out that he was still unlocked, I used the command "fastboot getvar unlocked" through ADB. THen I thaught i had to install back TWRP, tried through the fastboot mode but I had an error
Code:
FAILED (remote: unkown command)
since i tried everything i could even in the basic recovery mode, the only working command in the recovery is "fastboot flash recovery twrp.img" but still does nothing.
I mean it's not that terrible since I can use my phone and i'm about to change phone in 2 months for a Oneplus but i would really like to be able to install magisk on the phone to grant root access and be able to use TWRP on it like I used to. By the way the backup of lineageOS has been deleted while performing unecessary wipes.

It's clearly written on the official website and in the official TWRP support thread for the g4 what you have to do when on Nougat bootloader and want to flash TWRP... and keeping it.
Sent from my LG-H815 using XDA Labs
Yet, this still doesnt help me to solve my issue. Do you think there is a way to fix it or no ? If not, I'll just deal with it for the few months lasting.

Okay if it doesn't work for you you must do something wrong. It works 100%. If you really want help you should explain in detail exactly which steps you took as otherwise it's all just guessing what you're doing.
Sent from my LG-H815 using XDA Labs
Indeed, I didn't followed the procedure exactly, didn't do the step after flashing TWRP (removing battery and boot manually to recovery). Well thank you, was my bad on that.
Should I do a clean new install of cypheros or should I keep it like that, what would be your advice ? Knowing that at the moment CypherOS works like a charm. I also plan to install Magisk on it to root it.

TWRP recovery not working on Blackview BV9500

Hi everybody,
I try to root my Blackview BV9500 by installing first TWRP recovery. I use fastboot mode on a linux laptop to do that.
I successfully flash the twrp recovery image, but after that, the phone don't boot in recovery anymore.
It try to boot into recovery, but it reboot in normal mode a few second after.
I tried also with the cmd "fastboot boot recovery.img".
When i flash back the original recovery image, it work, i can boot the original recovery without any problem.
Does anyone have the problem?
Some one can help me to find a solution?
I, too, am trying to do this. I have not yet flashed it... I was going to use the fastboot boot command to boot the recovery kernel before permanently flashing it, to make sure it would work, and in my googling I stumbled across this post. Serendipity! [Edit 3: Although, reading your post again, I see you tried that as well and it didn't succeed for you. For me, it simply tells me remote: command not found, so how were you able to even get that to work?]
All that said... I have the BV9500 Pro, specifically for the two-way radio, so I'm going to try to keep that little tidbit of hardware working in the process. I mainly just want to tweak the menus a bit, tweak the quick settings, get root, delete the Google crapps I won't be using...
On to your problem, though, I can't help much but maybe if we post back and forth our successes and failures we might be able to stumble through it together?
First, I assume you already have unlocked your bootloader? [Edit: Honestly, I'm not sure flashing the recovery would be allowed without first unlocking the bootloader]
[Edit 2: Perhaps this thread might be of help. Different model, but often the hardwares used by manufacturers are similar enough that the same steps generally work. ]
Thank you for the link, maybe i need to flash the complete rom with the twrp recovery with spflash tools, and it will work.
I will try and let you know, but i will make a backup of my rom before flashing it!
For your problem with fastboot, maybee it's because you need to install it. You can use the command "sudo apt-get install fastboot" on a terminal window if you are on linux.
If you want to enter the recovery mode, you don't need to use fastboot, you can simply enter it by pressing Volume Up and Power buttons together for a couple of seconds when your phone is off.
When Boot Mode appears release all keys.
To flash recovery with fastboot, you need first to enable the developer mode on your phone (go to "Settings > About phone" and make 7th tap on the build number, the Developer options will be unlocked and available), and unlock the bootloader of course.
here what is the process i made to flash the recovery :
- i use the command "adb devices" to check if the phone is well connected. (response is like "BV9500S320001179 device")
- then i enter in fastboot mode with "adb reboot bootloader" (phone reboot and ask confirmation for fastboot mode)
- check with command "fastboot devices"
- unlock the bootloader with the command "fastboot oem unlock" or "fastboot flashing unlock".
- flash the phone with the twrp recovery with "fastboot flash recovery recovery.img"
- reboot the phone in recovery mode with "fastboot boot recovery.img"
Normally the phone boot in twrp recovery.
Hope that will help you too.
I am too facing this problem. In case you got any solutions please let me know too.

Yup. Already had fastboot installed for the LG G5 this phone replaced, the Galaxy Note 4 the LG replaced, the MyTouch 4G Slide the Galaxy replaced, my wife's old Galaxy S5 I used in the interims... LOL, I've got a working install. No, the "Remote: command not found" was returned from within.... Whether fastboot or adb, I forget now, but I was able to get the file to flash eventually, after reading your first post, but unfortunately the phone would not boot to it (nor Android). I thought I'd bricked it. Twice this happened. Each time, after about 5 minutes, it eventually booted to Android.
I flashed the recovery from the ROM in the link Blackview sent me and was able to boot their recovery just fine, so there's something in the TWRP that my particular phone doesn't like.

Thanks, I keep forgetting which keys to hold for recovery versus bootloader, so I use the adb command to be sure without having to keep a notepad nearby.
Clearly I don't do this as often as I used to.

Now that was something I haven't done since the T-Mobile G1 days. My understanding was that you CAN boot a recovery without flashing it first if you"fastboot boot {image filename}" but that didn't work for me either. I'm also assuming that the filename to flash can be anything because the device stores it to a partition, so it shouldn't have to be specifically "recovery-verified.img".
The recovery you have... Were you ever able to boot to it? If so, would you be willing to share a link to its download source, please?
I've got to run for a prior engagement, I'll check back later.
Thanks!

I guess i find the reason why the modified recovery image won't boot.
I find an interesting information in a post of osm0sis (https://forum.xda-developers.com/showthread.php?t=2073775) were he say : "some newer MediaTek (MTK) devices use special image signing that adds a "BFBF" pre-header signature, so images will unpack/repack but most likely won't boot unless run through their internal signing tool."
After more search, i find an interesting publication (http://www.lieberbiber.de/2015/07/04/mediatek-details-partitions-and-preloader/) witch confirm that.
They say in conclusion of the publication :
"Yes, I can confirm that SignTool is able to add digital signature information to firmware images. Signed images have an additional header “BFBF” and some fluff which SP Flash Tool checks on a secure device. Apparently some manufacturers merely used the default MTK key for signing the images, making them no better off than a typical insecure MTK device."
So we have to find another way to install magisk to root it.
Root 9500/pro
Mine rooted already....you guys can check on 4pda russian forum
Note : do not use the 17.1 version of magisk there because after reboot the device will freeze if you resboot after twrp 1st install...instead flash 17.3+ or 18+ right after first install of twrp...
EDIT : dont mind the russian language in TWRP as you can change it to english once there

Hi everybody,
I try to root my Blackview BV9500 by installing first TWRP recovery. I use fastboot mode on a linux laptop to do that.
I successfully flash the twrp recovery image, but after that, the phone don't boot in recovery anymore.
It try to boot into recovery, but it reboot in normal mode a few second after.
I tried also with the cmd "fastboot boot recovery.img".
When i flash back the original recovery image, it work, i can boot the original recovery without any problem.
Does anyone have the problem?
Some one can help me to find a solution?

Hello I have same problem... Do you have that original recovery file? I don't have and I would like to get that back. Thanks.
DL this:
needrom. com/ download/bv9500pro- bv9500-root/ (delete spaces)
- Copy Magisk-v18.0.zip and disable_encryption_9500.zip to external SD-Card or OTG device
- backup your data from internal SD-Card
- do a factory reset and turn off phone without entering the setup guide after reboot, or wipe via recovery and power off
- Flash recovery.img using scatter.txt with SP Flash Tool
- boot into recovery with hold down vol + and power
- switch TWRP to your language and install Magisk-v18.0.zip and disable_encryption.zip
- reboot and update or install MagiskManager-v6.1.0.apk

you can just download latest firmware and simply backup NVRAM etc with sp flash tool also flash with sp tool, you will have then working twrp with disabled encryption. there are tons of post regarding using sp flash tool on this forum
im using same phone and did these actions on first day and did not have any problem with twrp or magisk
Hi,
I've bought this phone in Pro version. I rooted my phone using needrom.com/download/bv9500pro-bv9500-root/ and adb after unlocking bootloader. Then I failed with errors. Then I used SPFlashTool in root mode with official 2018092919_s32v63c2k_jk_pro.rar rom (I don't find it anymore on the net but 1) I got it on Blackview official forum and 2) I have the file on my own PC) with format+Download and replace recovery with TWRP from Jemmini from 4pda.ru before flashing. OK.
Then I rooted again: format /data with TWRP, then install disable_encryption.zip, wipe dalvik, reboot on TWRP, then install Magisk, wipe dalvik, reboot normally.
Beware: TWRP is in Russian language at first boot, so to get it in English, first slide the first slide (allowing writing), then select 'Настройки', then the globe on top, then English, then 'Установитъ Язык'.
Hope this helps.
Then, this is my first rooted phone, so I plan to make a custom rom without Gapps (then maybe without Mediatek Ones and agold too) and remake all functionning with apps from Fdroid. Help needed on a manner of removing a system/vendor app properly. Help needed too to add V4A, as I could see max version supported is Nougat. I announce this here as my first post, but my project will be a full post. If someone want help please ask here or MP me
Note: an update of magisk is out (official 18.1), I installed it and my phone tells me a message that facial recognition was not working anymore then it only boots on TWRP... I reflashed it and my phone boots normally again. Wait and see...
Thanks to Jemmini from 4pda.ru again.
Bests Regards

It'd be great to have another rom but I'm facing a problem with battery life. Basically mobile network standby drains 5000mah battery every day i turned off from developer option but still problem is there. I have checked every single post on Google but nobody has solution for this. U guys face this problem too?

New update has been released today. It solves some battery issues, but be very careful.
I installed it, having TWRP and now I'm stuck in TWRP. I've tried to wipe everything but I'm still in TWRP.
I'll try SPFlashTool ... hope it works.
Everything restored & updated.
Using SPFlashTool I flashed all files included in 2018092919_s32v63c2k_jk_pro.rar (including original recovery instead of TWRP).
After that, Android booted and then, using OTA, I updated to latest version.

The latest version is not on the forum. I installed via OTA.
But if you mean the previous firmware, there is one link on the blackview forum: http://bbs.blackview.hk/viewtopic.php?t=480235#p795494
SP Flash tools are well documented here: https://forum.xda-developers.com/showthread.php?t=1982587
And a complete list of blackview bv9500 / bv9500 pro files and instructions (in russian): https://4pda.ru/forum/index.php?showtopic=931296
Hope you find what you are looking for.
@kanadali,
for the moment I'm not facing battery drain because there is not simcard in it at this state of my modifications, sorry.
@Reflected_God,
I think this is the link I used, I use the 2018092919_s32v63c2k_jk_pro.rar rom for base.
For all others who faces big problems like me (facial recognition not working then reboot on twrp only, I could reflash my phone with SPFlashTool, the rom and twrp from Jemmini/4PDA in russian only (others don't work for me). I used Format + Download in root mode on Linux. Then format /data with TWRP, then install disable_encryption.zip, wipe dalvik, reboot on TWRP, then install Magisk, wipe dalvik, reboot normally. Do other things. To remove gapps I disabled/force stop it before remove with TWRP. Others apps I can't disable simply remove with TWRP. I test if I encounter bugs but none for the moment. If someone wants to know what I do I've made a LibreOffice Calc sheet log, which evolve when I have time
Hope this helps
Bests Regards
Need Files or a GOOD guide. bv9500 NOT PRO.
If someone could upload the exact files that they used, and the exact same steps, that would be great. Please mention what stock version you have and a link to the image if possible as well. I've followed numerous different guides, with multiple different rom versions, multiple different recovery imgs, used sp flash tool and adb/fastboot multiple times, tried making sure everything was unlocked before each try, have all the necessary drivers, and the closest I get to a functional twrp recovery is a green line that appears at the top of the boot screen before it reboots. Ive tried going to the source, the russian site, but all of the links are 404ed. if not for me, then it would be great to just have this all in one place. Thank you please future hero.
Please include exact program versions (ex SP Flash) as well if not zips of them. I am sorry to be asking so much in one post however I truly didn't know what else to do. And I am typically very good with my google fu xD
I currently have build number BV_BV9500_V1.0_20181026. That seems to matter I believe.
I second the notion.
I have the pro model. I have considered rooting it, but honestly, the phone works well enough as-is without root (for me). However, I'd LOVE to be able to play with different ROMs on this device **AS LONG AS I CAN MAINTAIN THE TWO-WAY UHF TRANSCEIVER FUNCTIONALITY** (i.e. not some "needs-a-network-of-some-kind" "walkie talkie app" like Zello but the real UHF two-way), and I'd LOVE the ability to play with the files associated with the radio to really explore the hardware's capabilities.
Unfortunately, this phone seems more popular in [North]eastern Asia than anywhere else so I don't think we're likely to get much on this forum regarding it unless and until BV become a popular name in the western hemisphere.
