Help: New phone in bootloop after ota update - Xiaomi Redmi Note 4 Questions & Answers

Hello everyone,
Yesterday I received a new note 4x. Inserted SIM, configured it and all was fine. The seller had changed the firmware to a global stable version and had not unlocked the bootloader.
There was an OTA update so I clicked yes and downloaded it. When updating, the phone got stuck in bootloop and can't get out of there... Until finally battery ran out.
I don't know what to do. As the bootloader is locked I can't flash a new firmware.
Anyone can help??
Thank you

Trouble Updating to 4.1 please Help

Hey Guys,
I've been trying over the last month to update to the new JB update and I think I've tried everything... I'm rooted, but I don't believe I'm unlocked (bought this 2nd hand back in March).
I'm currently on the IML74K.US_epad-9.4.2.28-20120525 build number. So I'm assuming I'm on the U.S. SKU (bought it in Canada).
Here's what I've tried based on posts:
1) Factory Reset, restore default build.prop and try firmware update via OTA.
No Luck
2) download update from Asus website unpack and put onto external SD card. Click update, the tablet resets, the Android guy shows up and eventually he goes dead (red exclamation). On reboot it says I downloaded the wrong version of the update package or something.
Anything else I should try?

[Q] AT&T trying to update Galaxy S3 while rooted & TWRP Recovery Installed

Hi guys
I just got my wife a Samsung Galaxy S3 I747 for ATT using Straight Talk. I purchased one for my self about 3 months ago, same model. Both were purchased used, mine had 4.1.2 and my wife's has 4.1.1. I rooted and installed CWM Recovery on mine. I wanted to update my wife's to at least 4.1.2 like mine or even 4.1.3.
From my understanding, once you root and install a recovery mod, such as TWRP or the ClockWorkMod Recovery, that your phone will not be able to update via your service provider.
The problem is, I got her phone yesterday, and I tried to update it, but it kept saying it was at the latest update/firmware. I even installed Kies, but it reported the same thing. After a few hours, I decided I would root it and install TWRP and maybe install a new ROM with the FW on it later. Well, this morning, the phone reported that an important update was available. Somewhat confused, b/c I thought it couldn't be the FW b/c yesterday it said the phone was at the latest FW, and plus the fact the update is, as I thought, refused by the service provider or phone, when it is rooted or a recovery mod is installed. When it finished, of course it asked to reboot. I was curious how this was going to play out.
When it rebooted, it loaded the TWRP Recovery. Being still new to all this, I wasn't sure how to proceed, so I clicked the reboot button, but nothing happen, so I tried the shutdown button. The phone powered off with no issues. I turned it back on and it loaded successfully to the home screen. I checked the status of the update, and it said it failed. No surprise there, I'm just happy it didn't brick her phone during the process.
Is this normal? Should I just disable updates from my provider? Is it possible to install the update and then just reapply the root and recovery mod?
Thanks
Mike

It is perfectly normal. You described the expected sequence for a phone with any custom recovery. OTA updates download then reboot into stock recovery. Absent that ..what you said.
For your update path, I. urge you to visit xda's i747 forum & read up on the controversy & pitfalls of AT&T's OTA 4.3
Look out for:
locked bootloader
Knox Warranty bit
one way upgrade
(on pain of brick)
It's different this time around.

[Q] Verizon Galaxy Note II Bricked?

I was trying to update my Verizon Note 2 (SCH-i605) from 4.1.1 to KitKat. Unfortunately, my boot loader was locked and now all I get is a 'System software not authorized by Verizon...' screen at boot. I've try several tutorials using Odin to restore stock but nothing works. Has anyone else had trouble doing this? Is my phone permanently bricked?
can you get the phone in download mode?
also what did you do to get where you are now, we need some more details in order to help.
I got it back up and running. I got into the predicament in the first place by not unlocking my bootloader. I was trying to flash back to stock with a rooted version. When I used the unrooted, it worked fine.

Recently bought used Z2

I recently bought used Z2 3gb/32gb version with .291 Marshmallow already installed.. Everything is good until later this evening, after 4 days of using it, I got notification about new system update. When I downloaded it and install, phone just reboot and 'Could Not Install Update" appears on home screen. I just wanted to asked if it really software update or just an error or something? Thanks in advance
I think .291 update was the last official update from sony.
I remember, there was a custom ROM for locked bootloaders, means based on stock, provided with many updated or ported apps from the Z5. There was a bug inside with the Sony update service. A potential update is available, but as i said - it was a bug in this ROM. The message can be ignored, just freeze the app.
The more important question for me would be - was the phone ever rooted, and if so, was or is the bootloader still locked, re-locked, or open. If the bootloader is open your drm keys are lost forever, if it's re-locked without restore the TA-partition, the keys are lost forever too. So, how is your camera quality in dark scenarios?
The thing is - if you bought an unlocked phone without that you know it, it's less worth than a 100% original phone. How much did you pay for it?
If you want to be sure, flash the latest fw with flashtool 0.9.18 , it was .291. The message should'nt appear again. There is and was NO Update available.

If i factory reset rooted phone, will officially firmware update work?

Hi. I had rooted a galaxy s10 lite, android 11 of a friend of mine. He doesn't need root any more. If i go to settings and search for an official update, it gives me, "phone is running an unofficial firmware and can't be updated" or something like this. Phone is running official firmware but rooted actually.
So if i factory reset from settings I'll obviously loose root. Phone will boot i suppose, if nothing have changed resentlly. Will update then works? He doesn't have a PC. Or because bootloader will be unlocked, will still make update not working?
Thanks,

hello colleague
First of all, back up your information.
You will have to restore the s10 lite with the system from odin.
the bootloader will still be unlocked (if you previously unlocked it)
once restored from odin, you will be able to install updates over wifi.
you can try
restoring from system, but I'm not sure if it will work.
if it has twrp.
If you decide to restore from system and it works for you, you can share your experience, for future reference.
having the bootloader unlocked does not affect ota updates
Thanks.. Yes i know how to do it in odin. That's what i want to pass as I'll probably factory reset his phone without a pc to a coffee shop for example.. When I'll do it, ill post, although i think i won't do it very soon.
