I have a Lenovo A390 and I want to put a custom ROM that supports english and Google Play store app.
It is currently using some Chinese OS without google Play app, so not much I can do.
Current status: It is rooted but I can not access recovery mode.
I used:
1. Root - Framaroot with the Boromir exploit, worked fine initially. Then I used Rashr.
2. Install Recovery - Rashr let me install TWRP so I installed LenovoA390_recovery.img and tried to reboot to recovery mode. At first time it worked, and I saw the TWRP application screen and did a full backup of my Lenovo_A390. Then I tried to install a custom ROM and I chose the image file and started to flash it. It went very quick and I rebooted it. It started again but same operative system came up.
Once I restart the phone and try to go to recovery mode I see the old Lenovo logo or similar with a small text below that it is entering recovery mode, and then it goes to a black screen and nothing happens.
Now I can not access recovery mode anymore, then I hold volume up and power button, all I see after a few seconds is the Lenovo logotype, and nothing else happens afterwards. I have tried to install the recovery image again (using Rashr), but I have the same problem all the time. It installs the recovery.img but when I try to boot into recovery mode, it is not working. I also tried with CWM recovery image, but I get the same problem. Lenovo
The phone is still rooted (Rashr is working) but I can not access recovery mode.
How can I get the recovery mode to work again, so I can install a different ROM without Chinese operator branding?
Thank you!

Guys, What can I do if my screen turns black every time I try to go to RECOVERY mode?
The phone works fine, but when I try to go to recovery it JUST GOES black and I need to power it up again. How can I fix the recovery?
I have tried installing TWRP over Rashr, and it installs well, but just can not go to recovery mode.
Also, when I try to go to FASTBOOT MODE by holding POWER + VOLUM UP buttons, I only go to FACTORY MODE all the time.
Why is this happening like this, and WHY can't I go to FASTBOOT MODE?
Is it the same ?!?
I followed this guide rootmygalaxy.net/root-galaxy-core-prime-sm-g360t1metropcs-install-twrp
After I used Odin to load the TWRP and restarted my phone. (Yes it was successful.)
Now when I do the 3 button combo to boot into download mode and factory reset mode etc
It just gives me the boot logo screen with Root Recovery is not Seandroid Enforcing at the top!
Did I just **** my phone?
P.S. I understood everypart of the guide except when I have to use the superSU file it says to download am I suppost to drag that into a folder in my phone or something....However this info does nothing if I cant fix the above problem.

I don't know what that guide is, but don't use it. Not sure if you got this figured out or not yet either, but just in case you didn't, here ya go...
1) You have to use this root first, Trapkernel by Shinyside.
http://forum.xda-developers.com/galaxy-core/development/kernel-root-root-sm-g360t1-5-1-1-t3203522
Flash it in the AP slot of ODIN & it will root your device while setting it to SELinux Permissive(ie. Not enforcing).
2) Then flash this TWRP by Shinyside, also in the AP slot of ODIN, and key combos should return.
http://forum.xda-developers.com/galaxy-core/development/recovery-unofficial-twrp-sm-g360t1-t3208853
3) As for SuperSU, after you've properly rooted and installed the right TWRP, then you just have to boot into Android and go to the Google Play Store and download the app called SuperSU by Chainfire. Then, open it and it will help you download the subinary that you need. It just helps you manage app permissions and lets you choose which apps you want to give root access to and which apps you don't btw.
Any further questions just let me know thanks.
NOTE: You use a different key combo to get into TWRP than into download mode btw. After properly installing TWRP, you reboot and use VOLUME UP and Home button instead of Volume Down.
My phone is stuck in a bootloop. Here's what I've tried so far:
Booting into recovery mode, but it won't go into it, download mode does work though.
Flashing the latest 7.0 BTU using Odin, it is successful, but upon reboot the bootloop is back.
Flashing to another 7.0 BTU, same as above.
Flashing using AP + CP + CSC in Odin, same as above.
Flashing TWRP, it is successful, but again, on reboot the bootloop is back and it won't go into recovery mode, I have held down the buttons on the black screen, I've tried holding them whilst flashing, I've tried with auto boot and without it, nothing works. I've flashed TWRP about 10 times now trying different things.
Tried using ADB to get into recovery using TWRP, but ADB doesn't recognize any devices, probably because I don't have the USB mode enabled? Obviously I can't enable it as the phone is bricked.
Any suggestions?
This phone is so thin, it won't even make a good door stop at this point.

Try flashing philz recovery that worked for me to get recovery working !
Do you know what version and where from?
I tried a few versions but got the "Recovery is not seandroid enforcing" error on reboot.
I also tried recovery.tar from arter97 com (can't post the link) - Now it doesn't show the above error, and the Galaxy logo is showing without rebooting every 5 seconds. At least it's something different. Still can't boot into recovery mode though.
Here is a video that can fix the bootloop of Samsung Galaxy phone, maybe helpful with you.

I installed stock Android 10 Q (from 9 P) via Odin on my galaxy tab s6 LTE, then i unlocked the bootloader and rooted with magisk (manager 7.5.1, zip 20.4) following the magisk git site installation instructions (which are a bit more complicated than from some third party sites.)
Everything ok, but then when i power off it reboots. It's not in a bootloop: it boots up normally, but if i can't power off then that's not good when I'm not using it. I tried patching again and checked i got the the same md5.
Eventually i found that if i booted to recovery mode and there i choose reboot, it reboots to unrooted, but it does power off.
To get root access again i start with the recovery key combination but let go at the splash screen before it enters stock recovery mode. This means that i have to reboot each time i want to either switch it off or have root (but not both.) It's good enough for now, so I'm posting this in case anything else has the same problem.
Hi everybody,
I tried to install Magisk 21.2 on my stock Oreo rom with Magisk 20.4 already installed. I've used the recommended method for installation in Magisk Manager, and I left the AVB/dm-verity option unchecked. It resulted in a bootloop.
Before updating I did a backup of the boot partition, so I could restore the previously working Magisk 20.4. Now I have two questions:
1) Is there something else I should do other than restoring the boot partition after a bootloop?
2) Is there a way to install the new Magisk or should I just dismiss the update notification?
Happened to me As well on my G6.
I had to reinstall the rom. good thing i had backup.
I've downloaded the zip file of Magisk 21.2 and flashed it with the rom after wiping almost everything, and even tried flashing a different rom with it (I'm using stock A9)., but it seems it resulted in a bootloop every time.
There is a new magisk 21.3 from yesterday, which i hope fixed those issues as i am not planning to go though that hassle again.
I tried the new 21.3, and still it causes bootloop, at least I'm glad I'm not the only one.

It happened to me, same setup as the OP and did the direct install method from Magisk Manager. My phone is stuck in bootloop at the triangle/! scrren and I can't access TWRP via the normal buttons manner. Also, can't get any ADB to detect the phone (I am using a new PC that probably never connected to this phone despite loading ADB, drivers, etc. - I am going to resurrect the previous PC to see if can connect).
May I ask how you restored the saved boot image? via TWRP restore?
I've rooted and played with many ROMs on various android devices, but I'm no expert and this one has me stumped.
Yes, I did a backup of the boot partition before flashing Magisk and then I restored using TWRP restore. It's not the first time that a new Magisk version causes bootloops on the G5, to I was prepared this time.
By the way, if you don't have a backup, you may try to flash the Magisk Uninstaller zip, and without rebooting, the old Magisk 20.4. In theory it should do the job.

Thanks, But how to access TWRP or flash the zip? I haven't found any technique to access recovery (Power+VolDn doesn't work, only allows Factory Reset screen). How to access Fastboot to use ADB (I assume that would be the technique)? I did manage to bring up some odd screen that had a two-line message about fastboot by, I believe, using Power+VolUp.
For clarification this is what I now have:
Phone off (remove battery). Insert battery. Press power button until brief vibrate (1-2 seconds). Release power button. Triangle with "!" displayed "Your device cannot be checked for corruption. Lock the bootloader. " screen displays for about 3 seconds, screen goes black a second or less. Back to the previous warning screen.
Press and hold Power button + Vol Dn acts just like the above, but if I press power + press/release/press/release... I can get the factory data reset (Yes or No(Exit) options) - I haven't accepted that.
I've tried connecting PC to the USB port and two things: as soon as I connect it, the phone powers on and does the looping again. My PC doesn't see the phone in Device Manager and ADB won't list it. I did (one time) manage to bring up the two-line fastboot message at the top of the screen.
BTW: when it first tries to power on, before the Lock the bootloader screen, there is a small, scrambled white area (text?) at the bottom of the screen.
I don't know when was the last time (if ever) I attached to the phone via USB (probably a few years ago when I initially installed TWRP). Haven't really done much other than upgrading TWRP (via TWRP), Magisk (via Magisk Manager), and the very occasional nandoid backup via TWRP (I have one from 3 months ago).
Any further assistance or info would be greatly appreciated.
To access TWRP, turn off the phone, then keep pressed Volume down+Power and once you see the LG logo release the power button and press it again. The phone should ask you if you want to reset everything: if you press yes and then confirm, you will:
1) Enter in TWRP, if you have TWRP installed, or
2) Erase the whole internal memory, if you don't have TWRP installed.
As you already have TWRP installed, it should be quite safe to go through the reset procedure, or at least that's what happens on my phone. If you don't want to take the risk, you can still use fastboot to boot a TWRP image you have on the pc, just write
Code:
fastboot boot <path_to_twrp.img_on_pc>/twrp.img
To do so, you first need to boot into fastboot: you can just turn off the phone and, keeping the Vol- pressed, connect the USB power cable to the phone. It will boot into fastboot.
One more method could be booting into download mode (Vol+ and connect the USB cable) and flashing an original firmware using LGUP, but that is way too much for a phone that already has both TWRP and fastboot accessible.

My phone never got past the bootloader screen (i.e. never got to the LG logo screen). When I booted into fastboot mode with the Vol+ button, I could issue commands like "fastboot devices" which would return that it saw my phone, but attempting to use fastboot to reload TWRP didn't work - some say the LG fastboot has been neutered.
Eventually, I had to indeed use LGUP/Uppercut and reload the stock Oreo and the phone came back up. BUT attempting to reboot into bootloader not only didn't come up in TWRP, but I got the little dead Android image. I ultimately had to downgrade to OEM nougat, jump through a few hoops, and finally got TWRP installed. Then it was just a matter of restoring a backup or reflashing a newer ROM (I ended up loading lineage 16, no gapps, with microg etc.).
Somehow the magisk upgrade really trashed my recovery partition somehow (??). I've always made sure to have at least a couple of TWRP backups, but this time I was screwed royally when I couldn't access recovery. I forgot what an ordeal it was to get TWRP & root on this phone originally.
Thanks for your help.
