flashing custom ROM with "Android.system recovery <3e>"? - Desire 816 Q&A, Help & Troubleshooting

Hello forum,
I have a HTC Desire 816 dual SIM and I would like to install Cyanogenmod.
Surprisingly, the recovery is not the HTC stock recovery, instead it is "Android.system recovery <3e>"
like this: http://forum.xda-developers.com/desire-816/help/how-to-restore-backup-file-t3026014
This recovery behaves quite different, so I can not follow the standard procedure to flash a custom rom on HTC 816g dual SIM.
What works:
I was able to root the phone (using Kingo Root)
I have a working adb root access to the device
I can boot into fastboot
Obviously Android.system recovery has access to external SD card as it can "backup user data" there
My Problems:
I am not able to install a custom recovery
I followed the instructions from https://wiki.cyanogenmod.org/w/Install_CM_for_a5dwg and I tried all 3 ways mentioned at https://twrp.me/devices/htcdesire816.html but the devise still keeps on booting into "Android.system recovery" (Vol. down. button).
My questions:
Is it possible to flash a custom ROM using this "Android.system recovery"?
How can i perform a backup of the stock ROM before flashing (this is essential)?
How can I restore the stock ROM from the backup using this "Android.system recovery"?
Thanks for your support

alternative strategie
Hello forum,
As working with the Android.system recovery seems to be difficult, I consider another way:
Is it possible to flash a custom ROM without using this recovery?
I read some articles mentioning MTK Droid Tools and SP Flashtools (eg. hxxps://forum.hovatek.com/thread-159.html).
Should I investigate this further?
Main points:
performing a backup of the current stock ROM
be confident, that the backup of the stock ROM can be restored, just in case...
flashing of custom ROM (hxxps://download.cyanogenmod.org/?device=a5dwg)
Does anybody have suggestions or experiences with this idea?
Thanks for your feedback.

i have the exactly same problem
any heeeeeeeeeeeeeeeeeeeeeeeeeeeeelp

Cyanogenmod does not fit
Hello Forum,
I got some steps further and managed to install TWRP recovery by doing this:
I performed a backup of stock ROM with SP Flashtool and MTK Droid Tool.
hxxps://forum.hovatek.com/thread-526.html
I rooted the device using Kingo Root (2 attempts)
hxxps://root-apk.kingoapp.com/kingoroot-download.htm
TWRP recovery installed using this Magic Tool:
hxxp://forum.xda-developers.com/showthread.php?t=2798257
performed another backup of the stock ROM using TWRP
Then I copied some different versions of official and unofficial Cyangenmod 12 and 13 ROMs on my sd card and tried to install it via TWRP.
But none of them worked [TWRP message]:
"This package is for device: a5, a5tl, a5dug, a5dwg, a5chl, a5ul;
this device is htc_a5mpg_dug.
Error executing updater binary...."
Any suggestions what to do?

What I have learned so far:
My device is a HTC Desire 816 G with MT6592 chipset. This is different from 816 (without G)!
816 G is not supported by Cyangenmod (and never will). For experienced porters (not me) there is some stuff for Mediatec devices at mtkroms.com
I have definitely reached my limits. After hours of searching I could not find a custom rom for my device which is ready to flash (without porting).
Is there anybody out there who could provide me and other readers of this thread a link to a working custom rom?

Rooting LG P930 Nitro Bell/AT&T ICS

I have just received my phone back from LG repair, they fixed it from being hard bricked. I have by now experienced all the error messages on the P930 and used all the solutions. The phone was stock Bell ICS, I rooted with TPSparkyRoot.bat installed CWM Recovery from Rom Manager tried to boot into cwm recovery and got security error long time no see error then just security error. was soft bricked from there only download mode was available. so I unbricked, flashed the v10f_00.kdz Korean rom which put me in android 2.3 or something and rooted with the root.bat no problem using the nitro easy unbrick solution. I changed it to english but my wifi and data didnt work to download the CWM Recovery from Rom Manager so I flashed the P930_UDT_v18f_04112012.exe. which put me in Android 4.0.3 Then I had to root using TPSParkyRoot.bat. I downloaded the CWM Recovery from Rom Manager but when I try to boot into recovery it soft bricks again and I have to go through this whole process again.
How do I get CWM Recovery to work so I can use a custom Rom, How do I flash to HO!NO V18f rom? Do I need to somehow flash CWM Recovery from the v10f_00.kdz rom, if so how do I do so? I have recovery-clockwork-6.0.1.5-p930.img onn my computer is this of any use?
I am trying to flash over to the cm-10.0.0-p930.zip I am currently in P930_UDT_v18f_04112012.exe rooted with TPSparkyRoot.bat. Can someone step by step this for me I just cant figure it out.
Follow this guide: http://forum.xda-developers.com/showthread.php?t=2044645
Since you already have V18f installed and rooted, you can skip to step 9 and start from there.
Also, if you prefer, you can stop after step 17 and use Rom Manager to install CWM from there.

Twrp flash successful, but cannot boot into it. Only stock recovery show up.

hello there. I have htc desire 816 that runs on android kitkat. I wanted to flash custom rom and followed all the procedures. I rooted my phone using kingoroot and also unlocked the bootloader from htcdev site. I downloaded the twrp image specifically for this phone and flashed it using the official twrp android app. it indicated that flash was successful. i tried to boot into recovery but i could not find twrp . I tried flashing twrp using fastboot but no difference. I even tried flashing cwm . they all indicate that flashing was successful but i couldn't boot into recovery. When I click on Hboot then recovery, it spits me back again to recovery option. Can you please tell me what's wrong here?

stuck in bootloader/recovery, can't flash ROMs.

Hello,
i'm stuck in a particular situation: i can use fastboot and i can flash recoveries but none of them can succesfully flash a rom. i want to go back to the stock Realme UI, my device is RMX1993.
i tried to follow the guide (https://forum.xda-developers.com/realme-x2/how-to/to-stock-rom-howto-t4014773) but the last recovery (rmx1993-sde20-stock_recovery-c05) can't flash neither RMX1993EX_11_OTA_1040_all_tSZ3Sf5A77NS nor RMX1993EX_11_OTA_1050_all_loALrMDyMrbs.
tried to flash trough orangefox or the last twrp that support ozip decription but the result is a "succesful flash" but a phone that does not go over the boot screen and it reboot.
i succesfully installed color os trough the proper old stock recovery and it said the installation was succesfull, but the problem was the same.
someone know where could be the problem?
You need to successfully flash Android 10 (Realme UI 1.0) before you can flash custom Android 10 roms.
Have you tried this guide: https://forum.xda-developers.com/realme-x2/help/how-to-flash-q-firmware-based-roms-t4115987
As for why your colorOS back up is not working i'm not quite sure...have you wiped your cache before booting to the color os backup?

Custom Rom Flashing Error: to flash additional zips please reboot recovery to switch.

So I want to root my Xiaomi mi a2 lite, because of it I want to install custom rom, but there is one problem:
while going in twrp recovery (using adb booting command) it gets error : 1; it says : "to flash additional zips please reboot recovery to switch to the update slot"
however, it only happens when I want to flash custom rom (tried 3 different roms), when trying to flash a custom recovery or ForcedEncryptionDisablerDaisy it flashes successfully.
any solutions?
some information :
it's my 3rd time flashing the custom rom on this device:
1) the first one was using the "classic method" (with twrp recovery)
2) the second one was when I got stuck in the bootloader and used XiaoMiFlash application for flashing.
i face the same problem
I have oneplus 7 and have the same issue

Click to expand...
Click to collapse
same problem here im wasting so much time triying to figure out how to repait the partitions or something, because somehow I had a partition B and now doesnt exist lol.
Hey, mates!
Anyone able to solve this?
I flashed TWRP and Magisk successfully, but every time I try to flash a custom rom it gives me the message "to flash additional zips, please reboot recovery to switch to the updated slot".
I'm on a Xiaomi Mi A2 Lite, btw.
Thanks in advance for any help!
ATTENTION!
I found a solution to the problem, all you need is just to install another recovery, I installed Orange FOX. And you know what? Everything worked. So just install via SD card Orange FOX and be happy!
Thank you, your Yasude!
My phone: XIAOMI Redmi note 10
OF does slot switching automatically? I managed once boot and install OF, wipe, flash SYberia, change slot, anti encryption and magisk, reboot to system. Unfortunately never work with lineage. But OF has options disable encryption and some measures against (i dont like them - own ota recoveries which always make a mess)
LOS dmesg complaints about damaged GPT and cant find many files even after edl flashing with original FW.
just install orange fox
