First things first.
I have too low amount of posts to post in dev sections so its there.
None of described software belongs to me. And im not responsible for damages.
!!! MI FLASH TOOL BELOW !!!

Okay so me and probably others have/had problems with unlocking your Xiaomi Redmi 4 Prime.
These are simple steps to succes.
what is needed: Redmi 4 pro, ADB drivers
1. Sign to Xiaomi and apply for unlocking http://en.miui.com/unlock/
It is important to add correct data.
2. Connect to your Mi account on the device and enable Find Device option under Xaiomi cloud
if it is done correctly u will be able to find ur device at https://i.mi.com/
3 Wait for permission u will receive SMS message.
4. When permission is aquired and device is connected to Mi Cloud we have to try to unlock the device.
5 . Download Mi Unlock software ( added to post up there )
6 .Enable developer settings
System info -> couple of clicks on MiUi version
Back - > more settings -> developer settings - > Enable OEM unlock
7. Reboot to fastboot ( Vol down + power ) till some (russian?) bunny appears
8. Perform unlock from Mi Unlocker and press
Left button
enter Login(email) and password to mi account
Connect the phone and press the button !
9 Reboot. You should be done Congrats !
You can install miui global now or any other rom. to Perform you have to :

I dont know but if you have installed non original rom isnt ur phone already unlocked?
Probably you can unlock your phone just make an application you can probably check the bootloader state from fastboot by
Code:
fastboot oem device-info
in fastboot mode

You can't!!!
You need to flash a official China Stable 8.0.5.0 ROM to unlock - tried it with different phones and methods...

I have not activated the "find device" and is still unlocked.

Hi
I have recently purchased a Redmi 4 Prime phone that came with the vendor rom and I wanted to flash the latest china dev rom, but am stuck in bootloop. cant enter DL mode, but fastboot is OK. unfortunately none of the adb commads work, the phone is recognized under "fastboot devices" but not under "adb devices". I have tried the fastboot2edl v2 method but is goes straight into bootloop. can you please suggest what to do and help me out?

Try to turn it off and press volume down + up and power until the LED flashes red and connect USB - it should be recognized as Qualcomm ******
If not, then build your own deep flash cable or order one on ebay or something... - with that u can reach the DL mode on nearly every Qualcomm device

Flashed the Developer Preview Rom and it worked

usually the issue with unlock is a different username used to login. use the same, either email, number or name on both.
should solve it.

Can anyone translate this to English?

Could make it easier to flash a new ROM

11 days ago I apply for the bootloader unlock.
I'm in trouble. I want to install an unofficial rom and this says mi.

Then use unofficial unlock.

Bricked phone.

Hello, i was given a blu R1 HD prime phone that was bricked by one of my relatives, according to him, he tried to do a format all + download on this phone, which as far as im aware, is a death flag, so i have here this bricked phone, i installed mrmazak's prime 6.1 no nv.zip file on this phone, but it still gives me the TOOL DL IMAGE FAIL, error i've heard a lot about, i also saw him saying "THIS IS NOT THE PACKAGE YOU NEED" in which case i can do nothing but ask, whats the correct package to get this bad boy up and running again? thanks beforehand.
PS: The phone is 8gb/1gb ram ver. was on ver 6.1, amazon before the brick, no OTA's.

For a device that was format all. Will need more partitions than are in that package you tried. Also I have tried to work with someone else who had the 8gb size device, we could not get past that error.
I do recall that the last last person got a new board for his phone and pulled the images from it to share. There is a link in the main thread somewhere. But , well even when he tried to restore his own backup from good device to the one with do error, it did not work.
NVM
I remembered it wrong. He tried to pull it, but could not do it.
Look through this thread. Maybe you can try to follow the advice I gave him, and it may work for you.

Well, from this mess in english, i can kind of attempt to understand that he tried to install v17 backup, and it didnt work due to the PMT CHANGED FOR THIS ROM, then he somewhere got a .bin backup for miracle?, and then silence, i dont know what else you tried suggesting to him since his english was so bad, i cant follow the steps, on another note, got that .bin backup? maybe ill try flashing it with miracle tool and praying that it'll work. Also, which V17 should i use, NVRAM or NONV

There is now a "repair rom" listed in an mtk support group I try to follow. I have not checked it out yet, but maybe it will help. Let me open this on PC to search for the link
this one was labled v6.4 firmware http://www.mediafire.com/file/6kys9896445l5sm/SP_Flash_Tool_BLU_R0010UU_V6.4_Firmware.zip/file
this is labled as a repair firmware http://www.mediafire.com/file/il54pxuvpkargtr/BLU_R1_HD_R0030UU_REPAIR_MT6735.rar/file
I would have you look at those , first i suppose.
if it does not work I do have backups made from miricle-box, but they are not uploaded anywhere right now.

Real appreciated, will keep you updated, if anything works ill post it here.

Alright, i tried the 6.4 rom, it didnt work, i had it already, i also tried to install the "repair firmware" but in the v5.1628.00.000 version of my SPFT it shows me "SP FLASH TOOL ERROR: (8417) THE LOAD SCATTER FILE IS INVALID", then i try on another version (v5.1744 & v5.1804), then tells me STATUS_SCATTER_FILE_INVALID (0xC00300001), i tried the fix copypasting the hashtags and general settings on top for both cases but that didnt work, i noticed the scatter file looks really weird, not like most of the ones posted here or elsewhere, its just a bunch of rows and not organized in the slightest, maybe i need to try using the scatter for my 8gb/1gb ram? since R0030UU is the 16gb/2gb ram's model code
---------------------------------------------------------------------------------------------------------------------------------------------------------------EDIT: Tried mixed and matching the every file from the MT6735 repair firmware with the ones it didnt have from the prime 6.1 rom whilist using said 6.1 scatter, still on TOOL DL IMAGE FAIL

Hello,
two issues.
first, the backup has scatter file formatted for use in miracle box, not sp flash tool.
next, The preloader on any updated phone has been changed and does not work to flash anymore.
So, what is / was version on your phone , so I can know if it should be able to work or not?

First: If I use Miracle Box Crack 2.27A, can it work? (Would I have to disconnect and connect the battery to start the phone again?)
Next: I unchecked the Preloader because once I leave a brick as a phone to leave marked that option
Version: (Screen OLD, Now is in BLU Screen) (Ohhh I never UPDATE the software, I never use ROOT, I never use debloat...)

Hi Mr Mazak
I had purchased non prime version of BLU R1 HD. I updated to the latest version via OTA. I had my phone rooted with super su and now wanted to try Magisk. After the reboot I had reinstalled the twrp recovery and did a format of all data on my phone. I am trying to install twrp but when I power on my device it is stuck on the boot loading screen. I have tried hold power button and volume down simultaneously and it reboots but gets stuck on the logo.
I tried using the sp flash tool to restore my phone to stock but it did not work. Get error S_BROM_DOWNLOAD_FAIL. 7d
My bootloader is unlocked.
Tried using adb commands but when I connect to the phone and run adb commands it says no authorisation.
If I can install twrp on the device then I will be able to install the rom from rootjunky, not sure if you require more info.
Awaiting your ananlys
Kind Regards

The latest ota blocks the use of sp flash tool. And the kernel exploit used previouls. But now there is new exploit. But you cannot boot so that is mutt point now

From what you say.
1. You had working phone with SU root.
2. You have twrp installed
3. You wiped / formated with twrp
4. You now only boot to a logo screen. No recovery, or bootloader?

THE previous thread my probleme i stuck in bootloop even if i flash stock or factory binray but i found a solution and fixed bootloop
but now i dont have imei 1 or imei 2 is unknown
and baseband for device is unknown
and the spen remote is connecting and dont connect to my note 9

so you initially failed to do something first and this got you in the state you are in.(what did u do?)
strike 1.
then you also failed at restoring from a backup.( by restoring your twrp backup that should at least have EFS partition saved if not all of them)( but you probably didint back up anything)
strike 2.
now, when you flash stock i don't think you actualy flashed anything and failed at that too.
strike 3.
so i belive the issue is reading and then understanding it.
no efforts from anyone in the forums can fix that. only you can.
so read up on:
what type/model of phone you have.
what OEM unlock is.
what version/model of firmware it supports.
how different versions of odin exsist to flash firmware.
how to use odin and fill up the proper slots.
where to download rhe correct stock firmware.
how to properly flash twrp and wipe/format to prepare phone
how to use twrp for backuping and flashing.
how magisk is required to boot a twrp/rooted phone ( prolly your bootloop issue originally)
once all of the above is mastered then all your problems will vanish.
good luck on the literature
(btw from looking at the pictures your modem(CP) or part of the EFS partition has a missing file(s). anyways nothing flashing the correct stock firmware can't fix)
and spen is bound to phones imei. so in this case spen will connect again once you fix by restoring stock properly.

and since I'm such in a good mood,if you properly went through all the steps explained before and REALLY restored stock and also if you are rooted find a way to open:
efs/imei/mps_code.dat
if you get an error while opening it just copy to sd card and open it from there.

Since you haven't rooted or flashed any other firmware why don't you approach Samsung support? Tell them I tried to factory reset and since then it was like this.

Hi, I had the same problem and managed to sort it out. Find your service provider firmware on Sammobile and download it with Sam firm, extract it and load I'm Odin all necessary files and good to go. After that you can flash with Odin android pie straight on your note 9. Let me know if you still need any help. Good luck.

I also have same issue on my note 9 due to sam fix tool

maybe they should call it the sam break tool.
where is the file located again?
id be curious to study it

Usually its a modem issue when that happens. Perhaps find the right modem for your device and use Odin. It used to happen to me when I flashed international ROMs on my n910t . I would have to flash my models modem and it goes back to normal.

so i belive the issue is reading and then understanding it.
no efforts from anyone in the forums can fix that. only you can.
so read up on:
what type/model of phone you have.
what OEM unlock is.
what version/model of firmware it supports.
how different versions of odin exsist to flash firmware.
how to use odin and fill up the proper slots.
where to download rhe correct stock firmware.
how to properly flash twrp and wipe/format to prepare phone
how to use twrp for backuping and flashing.
how magisk is required to boot a twrp/rooted phone ( prolly your bootloop issue originally)
once all of the above is mastered then all your problems will vanish.
good luck on the literature
(btw from looking at the pictures your modem(CP) or part of the EFS partition has a missing file(s). anyways nothing flashing the correct stock firmware can't fix)
and spen is bound to phones imei. so in this case spen will connect again once you fix by restoring stock properly.

Note 9 (atleast USA models) I thought couldnt flash TWRP. Unless you're in binary but not even sure if that works. Also it cant be oem unlocked. However in Binary of course. Is the S pen really bound to IMEI? My IMEI number is 000000000000000. Which it obviously was not that a day ago but my S pen still works as it should. Let me be a hypocrite but less filler rambling. I'm hurting for this answer as well.

If curiosity is your game I was stupid as no other and figured going into binary was the best way to get a new IMEI to a rumored black listed note I got on the low low. Erase EFS 1/2/3 without backing up. I'll take a bow for being stellar. Come to find out after the damage was done. The IMEI was completely clean and I just needed to switch service.

[GUIDE] Unlock bootloader of Lenovo Tab 4 10 with OEM unlock "greyed out" (TB-X304F/L and other Qcom tablets)

WARNING: DO THIS AT YOUR OWN RISK !!!!
I AM NOT RESPONSIBLE IF YOU START CRYING INTO YOUR BRICKED TABLET
This guide is only for devices with "OEM Unlocking" option greyed out !!!
Others can follow the simpler procedure mentioned in the TWRP thread...
Prerequisites:
QDLoader_HS_USB_Driver (Google it and find)
Hex Editor (eg. HxD)
PC and some brain to understand....
Procedure:
Install the drivers and hex editor.
Clone this repo to PC - https://github.com/Naveen3Singh/BLUnlocker (Thanks to the dev )
Extract the firehose file from stock rom. (eg. "prog_emmc_firehose_8917_ddr.mbn" for TB-X304)
Boot into edl mode using key combo
or using adb
Code:
adb reboot edl
Check the port number in device manager and run " dump_devinfo.bat ".
Mention port number and full path to "*.mbn" file (eg. D:\where\every\it\is\prog_emmc_firehose_8917_ddr.mbn)
A file named " devinfo.img " will be dumped to the working dir. Edit it using an HEX editor as shown below.
{
"lightbox_close": "Close",
"lightbox_next": "Next",

Firehose file for X304L if anyone needs it

Great! I also have this problem...
Does unlocking in this way factory resets the tablet?
Is the "firehose" file version sensitive (i.e., if I use the S001016 file in a S001014 TB-X304F will I have any kind of trouble?)
Thanks!

After unlocking, when u Boot into system it asks for a password, even if u didn't set one to start with (atleast in my case).
So you need Boot into recovery and wipe data.
Short answer: yes, factory reset is necessary.
Regarding file version, I hav no idea... May be u can give it a try...

May do it when i find time....
But there are many videos on the same procedure for other Qcom phones, you can get some hint from that.
If you are very new to this, i suggest you not to do, unless your are confident.

Can u tell where u got stuck ??

Work! You're GENIUS

hello,
I already root some device but here I'm stuck because I don't find the port number in device manager :-( drivers installed and "lenovo tab4 10" displayed in device manager. in properties I have : port_#0002.hub_#0005
I tried use 0002 or 0005 as port number but the .bat script failed each time. do I have correct port number ?
[EDIT] I have "failed to write hello response back to device" message and my tablet is in FFBM Mode.
[EDIT] in FFBM mode, my device is recognized in device manager (but i'm not sure to find the correct port and the script don't work) and in FastBoot Mode (first menu), my device seems to be not recognized in device manager. I guess that the script must be launched in this mode but I miss a driver. I install "adb drivers" + QDLoader-HS-USB_Driver_64bit_Setup drivers. What do I miss ?

REDMI NOTE 9 IMEI INVALID/NULL

Since your device is MTK there are multiple ways to change your IMEI.
You can follow this guide to change your device IMEI back to original. (Changing IMEI to a different value than the default IMEI your device came with is illegal in most countries)
If you hate the technical stuff you can use this guide instead, it claims to be able to change the IMEI back to default value automatically by using baseband. Here is a video guide.
It's untested though so use it on your own risk.
Hope I helped.

You can repair only imei for slot2 by yourself.
Only Xiaomi Centre can recover imei for slot1.
If you want to recover the imei for slot2, just follow this step:
1. Flash the ENGINEERING ROM: https://forum.xda-developers.com/t/...for-merlin-redmi-note-9-redmi-10x-4g.4227933/
2. Enter in META MODE using MODEM META: https://androidmtk.com/download-modemmeta-tool
3. Write IMEI for slot2 and keep blank/null for slot1.
4. Flash any other MIUI (or custom) ROM you want.
5. Backup NVDATA if you want to restore IMEI after.
Done.

No. Because that the step 1 is "Flash the ENGINEERING ROM".
Meta mode is not allowed on release versions.

If you are facing the PMT changed error, you are using a different scatter file than used before.
You just need to use the SAME scatter file.
Here, you can find scatter file for MERLIN: https://forum.xda-developers.com/t/...omi-redmi-note-9-xiaomi-redmi-10x-4g.4223097/
