[GUIDE] How to Fix the Recovery Bootloop caused by POWER+VOLUME UP - LG Optimus G Pro

Hello everyone,
today i have made a convenient little script by myself which shall help me being a flashaholic.
Many people encounter a bootloop and they need to enter the recovery by using the POWER+VOLUME UP key combination to flash some files to fix their problem, means any roms, kernels, apps and even other files.
After you finished your session in the recovery, you restart your phone and what happens....?
you get the boot loop into the recovery!
So... here is the fix!
How TO use it?!
IF you ever have to go into the recovery with using the POWER+ VOLUME UP keys,
flash all the stuff you need and then...
flash the attached file in this post and...
reboot.
What you have to keep in mind...
This script is based on this command which is explained in this post:
http://forum.xda-developers.com/showpost.php?p=53154404&postcount=10
These steps explained with the previous link is now reduced in this tiny handy file which does the complicated steps in one flash.
But always remember:
It only works when you enter the recovery manually by using these key combinations.
It does NOT work when you have used your OTA update!!
If you still have this issue, maybe this post can help you:

[Q] Flash failed and now stuck with "waiting for device" in cmd

Hi guys,
I just bought my One X today. Since it is my first android i am quite noob in all the issues regarding flashing/rooting.
I already unlocked the bootloader, install the clock recovery and then when I try to flash the new rom, i forgot not to extract the zip file so things start to mess up.
Now I am stuck at the HTC boot up screen. I have tried all the methods at:

but it doesn't work.
The problem is that when i type a command into cmd it keep showing waiting for device
So I don't know what to do now. I really appreciate your help if you could provide step by step.
Thank you so much
OK so as a noob you thought you'd try too root your 1st android phone after having it just one day??? oops! Lesson learned, next time read up loads first and maybe get used to the phone first before trying too root it. Anyway. . .
After installing Clockworkmod did you (as instructed in all the manuals I have read!) do a backup? If so just remove the usb, turn your phone off and go to the cwm boot menu and select restore. Fixed
recovery?
i see you have flashed recovery..
can you get to it??
Press POWER + VOL DOWN until it reboots and keep holding until u get to HBOOT..
from there select recovery and see if that shows up..
if you can get to Recovery, then you can either flash a CUSTOM ROM, or go back to STOCK recovery and then run RUU (a program provided by HTC that will restore you phone to stock) but you also have to relock the boot loader..
based on your choice more info may be required to help you
My best guess is that you have a messed up kernel...

Phone stuck at android logo

I searched the forums and Didn't find any answers that were helpful..So i am opening a thread..
I am using a huwaei ascend p6 using android 4.2.2, not sure about the kernel versions..
My phone suddenly restarted and is stuck at the android logo ..Its not booting up , it keeps restarting when i press the power button. I can access the recovery mode..
Can the experts please guide me on how i can get my phone to boot up and working..?
Download the update file and put it on a sdcard and in the phone, then install through recovery. The steps were discussed in detail recently, look around a bit.
ps: You will use your data.
Good luck!
Or do a factory reset from stock recovery. To boot on it press and hold all three HW keys or with > adb reboot recovery command from a PC.

This thread in particular has all the links and tools in one place. Also there are other usefull threads in the General subforum.
I haven't dealt with a bricked phone, and thus don't want to give you any false instructions and complicating the situation any further. I am running the B125 firmware, I think it's pretty good, if not the best so far.

Stuck in fastboot. No recovery... no bueno :(

So I had my ze551ml / Z00A rooted, was loving life, all was great. Then I tried getting XPosed access and didn't read up on it prior. Anyways, now my phone is stuck in fastboot, I'm able to flash partitions and all, including recovery partition, yet I cannot enter any mode but the hung ASUS logo, or fastboot. I weas even able to load CM's "upgrade to MM bootloader" package, but still the same thing only with green letters where they once were blue..... Please help, I need my beloved phone back.....
I'm not a pro but if you can access fastboot it is just a soft brick and I'm sure many people can point you on the right thread to recover it.
I've scoured the depths of both XDA and the ASUS forums, and while I've gained much knowledge of how I can possibly fix it, nothing seems to work. I go to select "recovery mode" and it instantly just boots right back in to fastboot.....

Thanks -- you can install giovix`s modder tool from general section
Set it up , use`return to stock option` --in that option , first select boot , then after- recovery(both will be stock)
You then can either
A- Reboot to stock recovery ,adb Sideload stock M -- Follow on to B-( to back-up stock before flashing)
B- Unlock bootloader again , flash twrp and root (if twrp version in modder is now 3.0.3.M4 you can flash lineageos)
---------------------------------------------------------------(if twrp version in modder is still 3.0.2.1 M - you will have to flash 303M4 in fastboot or in 3021M twrp.
1) You might be able to, fastboot flash 3.0.3.M4 immediately and forget above A&B completely
For 303M4 recovery see lineageOS in original android development section OP for download link

So I've yet to try your solution, but I do have an update, I was able to, one by one, flash all the stock files (stock as in the stuff I downloaded from asus site) and was almost able to boot to recovery, but when I got to the red triangle android, I couldn't get it to go further. I've heardf alternate key combos for proceeding from there, and tried them all, but maybe I'm just an idiot...... I'll try the giovix solution when I've got time (patience).
**when I tried flashing the cm upgrade package after that, it went back to square 1, so I gave up for the evening.**

Here's the thing. I'm super stubborn, and I think I know everything (cuz I do....) so of course I decided that I could figure something out, so I tried my way first............ didn't pan out.... anyway, I'm finding any time I flash a TWRP file, I have no access to recovery mode. Regardless if I do it manually through fastboot, or CM upgrade/downgrade or even the giovix fix (yes I tried it). My question is this, Where is there a return to stock option? of the giovix DLs I could find, I see a 'magisk root' 'TWRP' 'bootloader unlocker' and 'Xposed' tools, nothing else.... Am I missing something? or am I just skimming over that part?
I do appreciate all the help, seriously. Even if it seems like I'm not taking suggestions very well. It's moreso I don't have access to a computer most of the day, and it's not a huge priority since I went and bought a zfone 3 max a few days ago (decent phone for what it is....crazy battery life)
https://forum.xda-developers.com/zenfone2/general/tool-ze551mlmodder-t3458145
Functions:
1- Check connection status
2- Bootloader Unlocker
3- Flash TWRP 3.0.2-0 M1
4- Full-auto xposed flasher!
5- Full-auto root flasher!
5B- Full-auto root (Magisk+Phh's) compatible with 184!
6- ADB Shell
7- Return back to stock
8- Erase /system, /data and /cache for a clean upgrade
9 (HIDE)- Auto-reboot to bootloader
10- More functions inside!
well then forgive me for not downloading the correct option. I nowhere see this list among anything I downloaded, so maybe specify which is which ('full' or 'auto')....... I'm already downloading both of them again, because I'm not sure which I already had. But yea, one of the 2 only has the 4 options I mentioned.

So i finally see what you've been trying to tell me, and I returned everything back to stock, but I still have the same problem, recovery now loads but system wont boot up. I'll try loading the individual factory IMG files today, via fastboot, or should I use a zip file from Asus via recovery?

In stock recovery - choose update from adb -- adb sideload cmd is >
adb sideload MOFD_SDUPDATE.zip
Put .134 M asus firmware in adb/fastboot folder first rename it to MOFD_SDUPDATE(without zip) before this cmd above and then open up adb and type it in and hit enter.
Just in case you are trying different methods (see if this works )

I'll try it today. Last I checked it was hanging at the ”! Android” screen. But then again I'm not sure I know the combo to get passed that screen, I know it's either power and + or power and - but my only success I got into by button mashing all three keys rapidly, so, yea, I know, I'm am idiot.

EDIT"""" because i got it wrong too , i dont even think about , i just do it
It`s ->
From powered off position
Press Power and Vol +
at two vibes, release power
at boot up screen ,release vol+
in bootloader ,scroll vol up or down to and then select(press power) at recovery selection.
At dead android guy -> press vol + and power for 4 seconds -> release Vol +
You should be in recovery.
i am replying in this post since i have a similar problem, and I am as stubborn as OP. Me posting here is a big step in acknowledging my defeat at last. Hours of digging through the internet didn't solve my problem
I have changed my ifwi and dnx more times than i can remember. (my clean slate is mostly using xFSTK downloader with xFSTK_ZE551ML-sal358-amtech.vn files)
Using the above mentioned method (giovix`s modder tool) to go back to stock i still boot into fastboot, not recovery mode.
trying to unlock bootloader it says on the phone "unlock fail"
Using asus flash tool with raw files i get "gpt command failed"
Using a manual method i get the "gpt command failed" on the "6. fastboot oem partition /tmp/partition.tbl" step
in my opinion as soon as i get some kind of recovery my problems are solved. But have been working four hours on this problem with all possible solutions i could think of, nothing but frustration.
info: current ifwi 0094.0183 (wich should be M)
serial 01234........EF
and using the toolkit on "https://forum.xda-developers.com/zenfone2/general/bl-unlock-ze551ml-toolkit-t3546293" i found out my device firmware version is 198 (wich is probably not good in combo with the ifwi)
little update in a certain config (android 5 / ifwi 0094.177 / stock recovery) i can boot up untill the dead android icon, but with whatever key combo can't get past it... (vol up + power) / (vol down + power)
fastboot flash boot recovery.img (yep i am really desperate to get into recovery) doesn't even give me the dead android.
thank you beforehand!
Last paragraph with android 5 ifwi 0094.0177
Is your serial correct ?
Press vol + once is it correct?, if not you will have to xfstk first again and flash raw (twice) with temp bootloader 0094.1069
See my unbrick video for help
First of all, thank you very much for your reply!
I was not very specific there, the android 5 is not the rom (still wasnt able to flash the rom) its only the files like droidboot, ifwi, dnx, .... that i got form lolipop.
Indeed the serial is still 1234........EF (so not the correct one)
I do understand i have to flash the raw twice to get the correct serial, but flashing raw doesn't work. I get "gpt command failed" every time. (so the point where i have to restart flashtool is not even reached). Also if i try to do it manualy.
I watched your video (thanks it was my first steps into understanding how it all worked) but unfortunatly didn't work for me.
Any other ideas?

Did you get this device in this condition ?
If not, what happened so that you lost serial ?
Anyway , i have never tried this because i have ALWAYS succeeded flashing raw (twice) to correct serial BUT it may work for you.( i am not sure you have a device that can have the serial corrected due to whether its been tampered with previous ) which affects recovery and IMEI.
Usually , xFSTK is used to install temp bootloader - Its supposed to be the lowest level form of unbricking procedure and restores temp bootloader so you can fastboot after-- flashing raw in fastboot via AFT(twice) restores serial -- 1st flash approx 3mins is with incorrect serial and temp bootloader.
After a couple of mins, cmds on phone pauses on RESULT=OK on phone.
You close AFT and open AFT again , input raw and set AFT up -- press Vol+ on phone -> once, serial will be corrected and 2nd flash can be started and left until it boots into android 5 by itself.
If GPT trouble , that link may help.
There is other programmes for starting to create serial and restoring .
Usually people who use these , have to dig deep into buildprop stuff which if tampered with can end up with problem such that you have.
Good luck
see if anything here helps

problems flashing twrp

hello,
I tried to flash twrp to my p605 but when I boot to recovery I get this message " Recovery is not Seandroid Enforcing".
The only solution is to reflash twrp checking autoboot to fix problem. I have tried various versions of twrp. how I could fix this problem?
I am not rooted and I attach some info of my device.
thanks a lot.

It is likely you used the wrong TWRP for your Note (LTE version for P605). Be sure to use this xda forum for version and instructions. Sadly I have also made this error on various devices I have owned over the years. lol

The first method is to boot into recovery and wipe data and reset to factory. The drawback here is you lose (probably) all your data, and it may not work then you have to try the second method anyway.
1: Power off your Samsung Galaxy Note 10.1. Make sure that it's completely turned off, this is the tricky part because of the bootloop. It takes patience and timing.
2: Now press; power, home and volume up to enter the recovery mode
3: Hold the buttons for at least 5 seconds until the android logo appears on the screen
4: The screen will be redirected to the recovery mode of your Samsung Galaxy Note 10.1
Use the volume button to navigate between the options and power button to select the highlighted option.
The second method, especially if that does not work, is to use ODIN to re-flash stock firmware onto your device. That is a process that using search will get you great detailed instructions, much better than I can describe.

thanks for your time to help me. i downlaod twrp files from here: https://twrp.me/devices/samsunggalaxynote1012014qcom.html
I wonder if the new security udpate of february 2017 causes problems of installing twrp.
i will consider if i will try one of these methods.

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

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

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.
