Bootloop after xiaomi.eu latest stable upgrade

Handset: Xiaomi Redmi 3 Pro.
Steps done:
1. bought on aliexpress with some suspicious bloatware preloaded.
2. was unsure if bootloader is locked, so flashed modified bootloader and TWRP as per this guide: http://en.miui.com/thread-276565-1-1.html
3. flashed latest xiaomi.eu dev build: xiaomi.eu_multi_ido_6.5.26_v7-5.1
4. boot, reboot
5. flash SuperSU via TWRP: UPDATE-SuperSU-v2.65-20151226141550.zip
6. booted and used several days, few reboots. All working fine, except apps closing in background and bluetooth earpiece losing connection. Described here: http://forum.xda-developers.com/redmi-3/help/redmi-3-pro-impressions-closing-t3397186
Where problems have started:
7. Decided to get stable xiaomi.eu release. Maybe forceclose and BT issues are resolved?
8. booted to TWRP and flashed STABLE release from xiaomi.eu: xiaomi.eu_multi_ido_V7.3.1.0.LHPCNDD_v7-5.1.zip
9. also flashed SuperSU without restart: UPDATE-SuperSU-v2.65-20151226141550.zip
10. After restart, I get boot loop.
It does very short boot attemps: when powered on, it vibrates and displays MI logo for a second, then reboots. Repeats it quickly 2 or 3 times and switches off.
Unable to go in to download mode, as volUp + Pwr will also give bootloop.
VolDn+Pwr will load fastboot after one reboot. MiFlash utility finds the phone, but throws an error on flash attempt (file not found or something).
If restarted with all VolDn+VolUp+Pwr buttons pressed, it will not turn on the screen at all, but appears on MiFlash utility and I am able to flash it. But still bootloops after that.
If I flash it with original bootloader, not the modified one as per guide (on step 2), I am able to boot in to china MIUI, and also in to bootloader menu. But of course TWRP does not work.
How do I do it with locked bootloader:
1. flash TWRP?
2. flash stable xiaomi.eu release?
3. get root?
Of course all of this is needed only until stable CM comes out.
Also, if bootloader is unlocked, is it displayed somehow? For example my old motorola would show a nasty warning during boot.
Short update. I have managed to install the latest xiaomi.eu ROM.
Unmodified bootloader is needed.
Flash TWRP via MiFlash separately, after MIUI is installed and booted.
Then flash SuperSU and you're good.
EDIT: I lost all my data since the phone was encrypted, but I recovered it flashing in fastboot mode
My Redmi 3 pro is stuck in a bootloader after trying to root it for the first time.
power off doesn't do anything.
power and volume up doesn't do anything
power and volume down shows a Fastboot logo with a cartoon, but I don't know what to do here and if it is useful.
After 1-2 minutes in fastboot logo it starts again in bootloop.
I've tried to press both volume up and down and power and keep it pressed for several bootloop cycles. It looks like the phone switched off, or at least the screen was black.
After restarting it again bootloop
I think soon the battery will drain and the phone switch off
I really don't know what to do

XT1225 Boot Looping issues, Lost IMEI and No TWRP Recovery

Hello Everyone,
I own a Motorola quark XT1225 64GB indian version. I had earlier rooted it and installed Lineage OS 14.1 (Unofficial) in it. The installation was without any issues and worked for few months then one day i pressed the power button to turn on the phone and it went into a boot loop and nothing would work. i gave it to a repair shop and he installed android 6.0.1 in it and gave me back. But my phone wont connect to WIFI and later i found out that there was no IMEI or any network related information left in it. only the OS booted and nothing else was working. Even the Developer options were not available as for some reason tapping the build number was not giving any result. he refused to fix it. I tried a factory reset from the settings menu with no result. even the recovery was not available any more in the phone. I tried installing new android stock images both for android 5 and 6 first from RSD lite and fast boot mode which kept failing and then i tried it using the command promt. After installation was complete the phone rebooted and android appeared with erasing written under it but then it went into boot loop and would keep restarting every time android appeared. I tried installing TWRP recovery from the command promt the initial image of the recovery appears but then next second it says unable to mount data and keeps rebooting again and again. Kindly suggest ways to fix my OS as well as have my IMEI restored.
Really need help.
Thanks a lot.

TF201 suddenly bootlooping.

So I got myself a cheap TF201 tablet and decided to put Android 7.1 on it using this guide. I followed the instructions completely and everything went perfectly well.
Had TWRP 3.2.3.0 installed, Android 7.1 installed and it was working great. Rebooted a few times, set up my Google account in Android, started installing a few usual apps such as Chrome, etc. when suddenly the Pad completely locked up. It then rebooted and went straight to the TWRP logo screen, sat there for 10-20 seconds then rebooted. And now that is all it does - ASUS screen comes up for a couple of seconds with "This device is unlocked" in the upper left, then tries to go into recovery but it reboots instead.
I cannot access fastboot mode at all - holding PWR + Vol DN does nothing. I can access APX mode and I can briefly use ADB while the TWRP is up.
I have backups of all blobs and I have nvflash installed - I got through the whole guide step by step without a single problem.
Any help would be hugely appreciated!
I got quite the same issue here, I also flashed 7.1.2 yesterday and installed some stuff. Then today I wanted to install Magisk to root it. After the installation (I can't remember that it was successful but I think it wasn't because there was no Magisk app to find) I wanted to boot another time to the recovery and went into a bootloop. When I'm trying to boot to TWRP it stucks at the teamwin logo. Sadly I have no cable here at the moment to maybe reflash the recovery or try some other stuff.

Lenovo K4 Note Resurrection remix boot issue and recovery issue

All this started when I was installing substratum theme into my marshmallow phone (yes I know, this was the dumbest experiment I've ever done to my phone), and after rebooting my phone, somehow my phone is stuck in first Lenovo logo before boot animation, and somehow my entire system got bricked (including the charging screen when charging when the phone is turned off). After that, I'm installing the Resurrection Remix custom ROM the install was successful (except for 2 errors when installing), and after booting into the OS everything is okay. but the time I will install Gapps, my recovery won't even open. I have pressed Vol-Up+Vol-Down+Power as the instruction says, it just doing like a vibration loop (the Lenovo boot logo appears then the screen goes black, and vibrate, and the screen comes back on, and so on), and at one moment my screen won't even turn on, it's just vibrating. And now I can't even access the recovery.
My second problem is when I'm turning my phone off, its just starting up automatically, just exactly like a rebooted phone. And now I can't even turn off my phone.
Then, what should I do to fix that two things? Did I have to flash a new custom TWRP or flash other RR ROM? You can ask me for a pic or even video...
I'm an Amateur in this Android hacking and rooting, my only experience is rooting and completely modding my old phone (android 4.4.2). And sorry for my Bad English because I don't speak English very well
Thanks...

UmiDigi F1 Play stuck in a boot loop

Hello
I have UmiDigi F1 Play stuck in a boot loop.
So, the phone was working fine on "UMIDIGI F1 Play V1.0_20190903 ROM - SPFT + OTA release" updated via OTA. One day after a normal restart the phone went into a boot loop (UmiDgi logo, <thinking>, black screen (displayed not turned off), <thinking>, UmiDigi logo, and so on).
So, these are the steps I took so far with no luck:
1. Managed to get into recovery (pressing repeatedly Vol-Up while UmiDigi logo comes on), and did factory settings restart, still boot loop. "Mount /system" still boot loop. "Wipe cache", still boot loop. Also at times when I got into recovery browsing through the options was super slow - one pres vol-up or vol-down and it took three seconds to move to the next option in the menu.
2. Reflashed in Download only mode the ROM "UMIDIGI F1 Play V1.0_20190903 ROM - SPFT + OTA release" via SP Tools, still boot loop.
3. Downgraded using Flash firmware mode to the oldest available ROM - "UMIDIGI F1 Play V1.0_20190409 ROM - SPFT release", still boot loop.
4. Formatted everything including bootloader, flashed again the newest "UMIDIGI F1 Play V1.0_20190903 ROM - SPFT + OTA release", restored IMEIs, still boot loop.
4. Occasionally the phone loaded the system, but after system restart there is still a boot loop. Moreover, in the top right corner there are two lines saying "TEE: <Chinese symbols> Google: <Chinese symbols>" visible at all times in Android, despite correct IMEIs being present.
5. Flashed again the newest "UMIDIGI F1 Play V1.0_20190903 ROM - SPFT + OTA release" but this time I've read somewhere to press and hold both vol-up and vol-down before connecting the phone to the computer to supposedly enter safe mode. It only resulted in displaying single green pixel in the top-left corner at all times in boot loop.
6. I've unlocked the bootloader via Developer options in Android when it miraculously loaded. Tried to flash TWRP via ADB - the phone displays that bootloader is locked. Tried flashing TWRP according to the instructions on the UmiDigi forum via SP Tools and there is a text under UmiDigi boot logo saying "Red state <you're using custom recovery use OEM recovery this will not start>". The text is displayed for a very short period of time and the phones goes again into a boot loop.
So to sup up:
- the phone has the newest stock ROM "UMIDIGI F1 Play V1.0_20190903 ROM - SPFT + OTA release"
- is stuck in boot loop (UmiDigi logo, <thinking>, black screen (displayed not turned off), <thinking>, UmiDigi logo, and so on)
- in the boot loop there is single green pixel in the top left corner at all times
- when the system occasionally loads there are two lines visible at all times saying "TEE: <Chinese symbols> Google: <Chinese symbols>"
How do I fix that guys? Any ideas?
SOLVED
So, I solved my bootloop issue.
The reason for bootloop was faulty fingerprint scanner. I've disassembled the phone, disconnected the FP scanner and phone boots as it should.
However, don't throw away FP scanner if you won't replace it. You will need it if you will want flash in the future anything via SP Tools - flashing without will result in bootloop.
so how did you get rid of the chinese red letters??
