reflash stock rom without recovery - Xiaomi Mi 9 SE Questions & Answers

Hi guys
I'm sending my phone to the repair centre to repair the ghost touch issue.
I need to delete all my private data but ghost touch means I literally can't navigate my phone.
The only way is to reinstall the stock rom from bootloader but I need to be careful not to unroot my phone.
Please can someone point me in the direction of the correct guide to do this.
I have a Chinese version phone that was rooted by the aliexpress seller and pre-installed with global rom.
Thanks in advance

[Q] Return to stock?

Hi, I sold my EVO on eBay and I need a way to return it to stock software. Thank you!
Download and flash the ODEXED version of the stock rom from here. Remember to do a full wipe/Factory reset prior to flashing. NOTE: The EVO will still be rooted.
Can I unroot it?

Sure you can, but why? You are selling it, right? It will still work normally and if the buyer is into rooting, he or she will be grateful and if the person is not into rooting, the device will automatically be unrooted when he or she accepts an OTA update from Sprint.
UPDATE: follow the steps here to unroot.
In the meantime, I don't want a problem with an inaccurate item description, as they make take it into Sprint for something.
I understand and updated my previous post to include a link to help you unroot.
Thank you 10char
You're very welcome. Enjoy the rest of your day...
How do I eliminate or decrease the possibility that it can't be rooted after O di this?
I'm not sure I follow you. I mean there is nothing you can do to prevent the buyer from rooting if he or she wants to do so.

Ok please help let me know what you guys think...
In theory could this same thing work given the following situation. My phone is rooted but the power button recently shorted and stopped working. Sprint didnt flag my phone as rooted but said get it back to stock and we will exhange it. Do you think it could work if I flash the odex using Rom MANAGER which ive never used to flash but im useless flashing through recovery with no "power button" to use as enter. Once I flash the rom using rom manager it will be back on sense from there can I then unroot without using the power button though bootloader or even HTC Sync because at that point I think HTC sync will recognize it? I hope all that makes sense im just trying to get my phone replaced. :/ Thanks!
**UPDATE** Scratch that Rom Manager took me to clockwork

[Q] Warranty...?

Hi, Hope some1 can help me!
ok.. so i have been installing custom roms etc within the last couple of months.. the latest one i used was RCMIX3D Runnymede. This was working absolutely fine until one day the WIFI, the bluetooth, and the up and down volume keys all stopped working. When trying to turn on wifi it says Error. same with bluetooth... i have tried absolutly everything to sort this out. different roms etc.. the volume buttons don't even work in bootloader recovery mode!
I have now managed to install the RUU stock rom 1.32 using my laptop.. and still nothing works..
so i'm thinking must be a hardware problem?! and wanting to send to HTC for a repair... thing is.. i am wondering will they know i have rooted and installed custom roms etc?.. as i now have stock rom from RUU and will update to 2.3.5 via OTA on my 3g network..
Is there anything else i need to do? or have i messed up my chances to get my DHD repaired on the warranty?
Really hope somebody can help!! as this is doing my nut!
Cheers
Garry
hardware failure most likely if its not even working in recovery
my vol - doesnt work, im waiting for the day when the vol + goes kaput as well ,, a weak link in an other wise excellent phone
sometime i think engineers at htc went for lunch when it was time to make the volume rocker
Surely somebody would know if rooting etc would void the warranty?! i have stock rom and now unrooted......
I've just sent my phone back for replacement (long story short, HTC didn't repair my phone completely when they were supposed to, I had to take my phone back, didn't have time to replace it, and after some haggling I finally have got them to get a replacement sorted for me). I sent it back rooted, but with stock firmware (apparently Mac users don't exist, and I'm not installing a copy of Windows on my system just to unroot my phone).
Note that in the Nexus One warranty policy, there was a clause "h", which stated that rooting voided the phone's warranty. None of the phones since, whether that be the Desire or the Desire HD, have this clause. So it is safe to assume, and you have a strong point to argue, that rooting does not void your warranty, though if you come to brick your phone, of course, you won't be covered.
There is no other clause, apart from this clause "h", that covers software; it all covers hardware failure.
Finally, there are loads of stories that I've read of people sending off rooted phones for repair, and them coming back rooted, whereas there are few of phones being rooted, and being refused repair. Also, as you will know, to restore the phone to a standard, completely stock, factory fresh state, all you do is run the RUU; sending a phone back when a simple RUU restore is possible, to me at least, would not be economical, both in terms of time and money.
Get it back on s-on using Easy Radio tool v2_2 found here on xda http://forum.xda-developers.com/showthread.php?t=857537 and unroot and it should be fine.
However I understand you canĀ“t use volume buttons, but well if you can root the device with visonary then you can do s-on using the tool I mentioned.
After that call HTC explain them your problem and send it for repair. I guess they will not find any traces that you used custom roms and also I heard from several people on www.tweakers.net who used custom roms and even didnt return it on s-on still got there warranty when they had it go for repair.
But most important don't mention about root or custom roms to HTC, aslong as you do that they will probably give the warranty and also HTC is not one doing the repairs it are external repair companies so it might be different for each country.
And yes if you would still have the custom rom on it would void your warranty, that's why I would always put it back to stock if possible, but about root I don't know, but before In returned in my phone for repair I just did a factory reset so that all data was gone and any traces off root.
Thanks for your responses,
I've since found a link on another site.. which shows somebody with the exact same problem and has got HTC to admit its this is a known fault.
http://androidforums.com/desire-hd-support-troubleshooting/300012-wifi-error-bluetooth-wont-connect-volume-button-not-responding.html
i'll crack on with the S-on thingy and call them tomorrow to send for repair or replacement
Cheers again for clearing that up

[Q] Full stock backup and restore

Hi!
Can i do a full backup my stock HOX? Maybe later if i need to use the warranty.
Can i restore the stock firmware and locked bootloader, so will be still warranty again?
How can i do this? Unfortunately, i can't find the answer for these questions.
You can do a nandroid backup to restore stock Rom ....but you can't show bootloader as locked...if you want to relock it it will show relocked....if you want warranty ...you could hard brick the phone...by flashing a kernel for another phone ...so theyll have to change the motherboard for free,or they will give you a new one...
Thank you for your fast answer!
But they can't see any log file in the HTC warranty service? The motherboard will completely breaks down?
I'm not really sure ...but I read that other people did that

Is using the box safe?

Hi, my HTC one M8 eye isn't working for about one week now because I installed a wrong ROM on it. I tried many methods to get it back working but all have failed. I messaged HTC service center in my country and they said they can't support it even if I pay, since it was damaged in a non technical way. So I sent it to a guy in a Mobile repair shop and after two days he said, something is preventing any flash ROM from being installed and that he has to use the box method to remove the cid and make the phone accept any custom ROM. Now, I don't understand what was he talking about and I fear this would lead to more damage. What shall I do?
Thank you in advance .

The tech guy is referring to the dedicated boxes used to unlock ,flash or repair mobile phones.it should be safe as long as the guy knows what he is doing.But I doubt there's a box that could change CID without the phone being s-off.
Flashing a wrong rom should only result to a soft brick.As long as you can boot to fastboot you practically can fix it with official methods like relocking the bootloader and restore with RUU.
or flash twrp and install a custom rom.
Yer im pretty sure they cant change CID without S-Off, i was looking at buying the Xtc2 clip. very similar, but doesnt change cid, and as already said, soft brick=easy to fix, i fear he may be trying the old garage mechanic routine, go in with a flat tyre, come out with a new engine lol.

Removing root without a trace for repair?

Hey all,
I've had my 10 for a few days now and love it, but last night I noticed a vertical line of dead/stuck pixels on the far right. I have a ticket open with HTC support and I need to ship it to them for repair.
The tech I talked to said an unlocked bootloader won't be a problem, but a rooted phone would require them to replace the motherboard and charge me for it. What is the best way to remove root access, TWRP, etc., without being able to tell? I've got a full Nandroid backup with the exception of data on an external SD if that helps. I've never had to go backwards in this process before.
Thanks for any help!
Run the correct ruu for your model
What if you have an international model with no RUU provided?
Flash unmodified system.img, boot, recovery
