Hi,
I just bought the 4a with TWRP preinstalled.
Installed LOS-14 from https://forum.xda-developers.com/redmi-4a/development/rom-lineageos-14-1-xiaomi-redmi-4a-t3727665
I did not install nougat as instructed in this thread -> backlight problem.
Since second boot it is stuck on LOS logo.
I cannot boot into TWRP, usually it booted stock recovery, from there I was able to start TWRP. Now always tries to boot los.
I can boot into fastboot, but fastboot program tells "no permissions".
ADB lists the device when booting LOS, but too "no permissions".
any ideas how to unbrick?
thanks
ps. I have got a TWRP backup of all partitions (system, recovery, persist, efs2, efs1, cust, boot)
solved.
use Vol-Up+Vol-Down to boot into TWRP
if this does not help try

Wipe your phone and re install it . it will start
Hello,
Would appreciate your help with this.
My device was officially unlocked, used to have lineage installed.
Once I've tried to install the recovery official global MIUI 9.1 (from
thread-1001529-1-1.html at en.miui.com) I got to a boot loop and now I can only boot to TWRP or to fastboot screen.
in TWRP, when I choose reboot, it shows me a message saying: "no OS installed!, are you sure you want to reboot?"
Would advanced wiping (other than Dalvik/ART cache , Cache & System) might help?
Any other way to go here?
Thanks,
Buli
Sounds more like you need to reinstall OS.

Hello, everyone!
I hope anyone can help me.
Yesterday I assisted with rooting and flashing a Mi 9 T Pro with Xiaomi.eu firmware.
Here are the steps which were done:
1. Unlocking bootloader via MiFlash Tool.
2. Flashing TWRP (this one: https://androidfilehost.com/?fid=6006931924117906979)
3. First trouble: It only booted once into TWRP with "fastboot boot recovery xxx.img, after formatting data and a restart of TWRP it refused to get access again, neither with a command nor with hardware keys. It was stuck in fastboot.
4. With the MiFlash Tool I reverted to the stock global (this one: http://bigota.d.miui.com/V10.3.1.0....M_20190805.0000.00_9.0_global_135788d537.tgz)
5. After successfully flashing the stock ROM, I downloaded and flashed this TWRP: https://www.androidfilehost.com/?fid=1899786940962577905
6. Flashing this version of TWRP went perfectly fine.
7. In TWRP I formatted data again. I restarted TWRP and copied the following files to storage:
ROM: https://androidfilehost.com/?fid=1899786940962578113
Magisk 19.2.zip
Disable_dm verity_ForceEncrypt
8. I wiped Dalvik, cache, system and data.
9. I flashed ROM - it went through without problems
10. I tried to flash the dm verity, then an error occurred (please see the attached picture).
Can you please tell me what I'm doing wrong? Root is mandatory for me, I definitely need it.
I'm looking forward to your input and your help, it's very appreciated!
try to unmount system then flash it again

Thanks for your input. I tried that, unfortunately this didn't work.
But I found the solution a few minutes ago:
I downloaded TWRP 3.3.1-13 (one version newer) and flashed it inside of my old TWRP. I rebooted to recovery again and then flashed Magisk without problems.
(The dm verity still refuses to install but the phone is booting and running.)
Well, it always work for me, or simply reboot recovery also work. Try wzsx twrp, it has remove DM verity & forced encryption remover in advanced menu
Hi all,
I was on xiaomi.eu MIUI 11 ROM for some time, but wanted to switch to either Evolution or Syberia ROM.
I did a complete wipe and installed evolution os trough twrp... but i forgot to remove encryption so i bricked my device...
So then, I flashed the latest stock rom (11.05)with Xiaomi flash tool, but then i was stuck with the chinese ROM so...
1. I went back to bootloader and flashed mauronofrio's TWRP recovery .
2. completely wiped phone; Cache,System,Data,Internal storage
3. copied Evolution OS 4.1 to my phone
4. installed zip trough TWRP, all successfull
5. but then when rebooting, TWRP says:"No OS installed, do you wish to continue"
6. i tried other ROMs like xiaomi.eu and syberia, but these would either give me the same problem, or just bootloop until iam back in the fastboot screen...
Anyone any idea what iam doing wrong?

This works for me every time.
1 Flash the latest fastboot ROM.
2 Flash TWRP (same one you used)
3 Boot into TWRP (use the vol+ button when booting)
4 In format menu swipe to factory reset, then format data (VERY IMPORTANT this must be FORMAT not just wipe)
5 In reboot menu boot into recovery, this ensures TWRP correctly accesses the newly formatted data partition.
6 Copy over the ROM (and GApps, if needed and/or Magisk)
7 Flash the ROM, (then GApps if needed)
8 Boot into system and do the initial setup
9 If installing Magisk, boot back to TWRP and install Magisk.
There is no need to wipe anything else. There is no need to wipe anything again after installing. There is no need to disable encryption or dm-verity.

thanks, i always thought that a wipe was sufficient, or at least equal to a format... anyways will report back later when i have time to try it. lets hope it works because i can't handle this chinese rom

The format is needed to temporarily remove encryption
I've just remembered that I missed an important step. Call it step 1.5
If you going to flash immediately after flashing official MIUI you must boot into MIUI once before doing anything else. You don't need to go through the set-up, you can boot immediately into fastboot after you get to the initial set-up page. The first boot finalises the install and is needed before you flash over the top of it. That may be the cause of your issue if you had missed this before.

Ok so i flashed TWRP again, rebooted to stock rom and then rebooted into recovery, but the stock recovery is still there.
When i flash TWRP and reboot into recovery immediately i can enter TWRP, but if i reboot the phone to MIUI and then reboot again, TWRP is gone again...
It seems like TWRP does not persist... now iam stuck again on fastboot screen because i wiped + formatted everything.
Edit:
When i want to flash recovery it says "OKAY" but it is unable to boot:
Sending 'recovery' (65536 KB) OKAY [ 1.562s]
Writing 'recovery' OKAY [ 0.333s]
Finished. Total time: 1.989s
Sending 'boot.img' (65536 KB) OKAY [ 1.547s]
Booting FAILED (remote: 'Failed to load/authenticate boot image: Load Error')
fastboot: error: Command failed

This is normal, MIUI will restore stock recovery of the recovery partition changes. In order to persist TWRP you need to either install Magisk, disable dm-verity or install a custom ROM.
If you are going to flash a custom ROM, then you should do so immediately after flashing TWRP.
After formatting data, TWRP has an issue seeing the data partition, so go to the reboot menu in TWRP and select to reboot to recovery.
Then you can immediately install the ROM of choice. You cannot boot back into system as you'll lose TWRP.

Ok, it appears that everytime i wipe system, i am not able to boot anymore into TWRP... Am i supposed to wipe System? or only wipe data & format data

There is no need to wipe system. You only need to wipe cache and dalvik and format data. (I choose to factory reset because it's easier in TWRP, but you could do advanced wipe and select cache and dalvik, then format data. Follow the steps exactly, but include my later step 1.5
I've just followed this myself today, as I've moved from LOS to the latest unofficial Havoc build.
In theory you could start by booting to fastboot and flashing TWRP again, then follow the steps from that point. You probably don't need to install MIUI.

Ok thanks a lot! So no need to wipe system partition after stock rom install. just wipe cache/dalvik/data, got it.
Most ROM install guides tell you to wipe /system when coming from stock rom. I guess this requirement has changed? or depends on what ROM you're coming from?
Use can use my guide
https://forum.xda-developers.com/k20-pro/how-to/simple-beginners-guide-to-raphaelin-t4020543
it has how to flash roms, and fastboot fix. (which tells why the Recovery isn't staying)

I need help... The reason why I'm flashing custom rom is, when the latest update came MIUI 12.5 android 11, all sensors of my phone stopped working like (Gyroscope, accelerometer, proximity sensor) I tied to flash the rom by fastboot method but still the problem persists. because of that I unlocked bootloader and flashed twrp. After flashing custom rom when I tried to boot it, it stuck on booting screen and when I tried to reboot into recovey it is showing fastboot mode. I'm unable to boot into custom rom.
