Unroot phone, lock bootloader and uninstall TWRP - Xiaomi Redmi Note 3 Questions & Answers

Hey guys,
i bought my kenzo with a vendor software without LTE support.
I would like to solve the issue with the non working LTE on SIM 1 with this tutorial http://forum.xda-developers.com/redmi-note-3/how-to/how-to-restore-lost-redmi-note-3-pro-t3401622.
Since I am not really happy about routing a new phone (just want to go stock as long as possible) I would like to know if i can lock the bootloader and especially remove TWRP after this procedure?
Can I just flash the global stable again or is there another process necessary?
Best regards,

[Q] Noob question: install custom rom / revert to stock

Hi all,
I'm quite new to the sony and android scene. My iphone 3GS broke down a while ago (actually I dropped it ) and I had it replaced by a Mini Pro.
I'm on the stock 2.3.4 rom and would like to test the miui version on this forum.
So, my question is simple: I need to unlock the bootloader to install a custom rom.
Can I revert to a stock rom (or upgrade to the new upcoming ics stock version) without loosing DRM etc?
And what's the procedure to do so?
you will have to follow this guide http://forum.xda-developers.com/showthread.php?t=1285285 that is the only way to unlock it without losing drm and the ability to officially update.
Looks quite scary stuff to me. Coming from a jailbroken iphone, it looks like this is a bit trickier. Thank you for the reply though
Another small question then: can I still upgrade to a stock rom version if I have unlocked the bootloader? (via an unofficial way that is)
yes you can, but if you unlock your bootloader the official way you are not going to be able to update using sony software.
and yeah it looks scary but it is easier than it looks.
Great, thanks for the info. I'll search around the forum for the unofficial unlock mechanisms and will have a try with them!

[Q] Couple things about Atrix 4G

Hi!
Im proudly owner of motorola milestone. It was great phone with blocked bootloader, but I'm old and I had in my live some "normal phone" so I didnt cry about locked BL. I simply dont need unlocked BL because in time when I play with Stone We had a lot of rom by recovery.
But from time when I made some weird things took a lot time and a lot of things change in new smartphones so I have some questions for You.
1) On milestrone I could without problems update 2.1>2.2 and downgrade it to 2.1 with official sbf, and I know Atrix has official update from 2.2 to 2.3. I still can make this without problems? (from 2.2>2.3>2.2 and other ways...)
1a) I saw news about update to ICS, and it Was on motorola page (forgot which one). It will be in this year? (official q3 2012)
2)Do I need to unlock BL to use "roms" from recovery? Or I need recovery only?
(like neutrino / cm7)
3) I will not use any of atrix accessories, it will be for me mp3 player, phone and maybe sometimes game console. I still need to unlock BL? And if yes, for what?
3a) when we are speaking about games, every rom fully support tegra?
4) Is something what I need to know about atrix 4g before I will purchase it?
5) Can any user of this phone who live in germany tell me what about using germany mobile network?
sorry for lame questions and thanks for answers

1. No. Due to bootloader changes between 2.2 and 2.3 you can't just use an sbf. You can however flash a fruitcake which is just a copy of the boot and system partitions. Doesn't do anything to the bootloader. Your bootloader needs to be unlocked to do this and you will need to flash a customer recovery program such as CWM. However, you can use an sbf if you are going between the same version without unlocking the bootloader. Example 2.3.4 to 2.3.4.
1a. Yes. We will should be seeing an ICS upgrade anytime from now to September.
2. Your bootloader will need to be unlocked and a custom recovery will need to be flashed.
3. If that's all your planning to use it for then there really isn't a reason you will need to unlock the bootloader.
3a. Every rom should as far as I know.
4. Some people report that the battery gets quite hot and causes problems. I'm lucky to say that I've had the phone for over a year and haven't had an issues.
5. Sorry, can't help you with question 5, but I hope I was able to answer the rest of your questions.
so without unlock bootloader I cant use custom recovery? In my MM I have recovery and from this recovery I can start "custom" and from this custom I can recover roms...
And what about update from 2.2 > 2.3, when moto release 2.3 for atrix it should be possible to update it without unlock bootloader? Only with OTA?
For god sake, why everyone are making us soooo much problems about custom OS... This is my phone and I should make with it what I want...

If you are planning on flashing custom roms you will need the bootloader unlocked. Going from 2.2 to 2.3 you don't need an unlocked bootloader. You should be able to either use the OTA option, the sd card option, or the update program from moto via the pc.

AT&T HTC One software update after rooting?

Hi Everyone:
I am so new to the development world. simple question:
I have managed to unlock the bootloader and root My HTC one.
How am I going to do software update later when AT&T release new one for the device? (I Know they are going to have the fixes for multiple bugs, like camera improvement, back and home button sensitivity issue, battery life, etc ).
will I loose the root after the update, or I can not even do update through OTA since I unlocked the bootloader?
will whatever way for the approaching wipes the data and apps?
How will it work? hope someone can answer my questions, thank you in advance!!
since you unlock the bootloader, you can not recived the OTA notification maybe.
I am in europe and I have to check for the update manually. I rooted the device and it is working fine. I tired to install the latest HTC software update (1.29.401.12) but it failed. It restarts the device and boots into TWRP.
Appreciate some insight.

I wouldn't worry about ota updates ever again. Every time an ota is released someone puts out a stock rooted rom you can flash via custom recovery.

[Q] Help rooting and installing rom Huawei y300

Hello there, how are you?
My problem is, I received an Y300 as a gift, haven't yet received it but I want to prepare the necessary things to root it and install custom roms on it. No, this isn't the first phone I install a custom rom to, as I have already played with an Optimus L5 of a friend. Could you please answer this questions?
a) How do I root the phone and install CWM or other recovery? I have found many tutorials but they are confusing, and require waiting for 2-3 days for the code to unlock the bootloader. In case you need to know, it probably is the normal Y300, the international one, so no Asian Model
b) How many ROMS are there for this phone? I like Cyanogenmod and stock roms the most, I can barely stand the stock rom in the phone, so I would like to install a new ROM on it ASAP.
c) By flashing the new ROM, do I lose IMEI or something like that (EFS Folder in Samsung phones)? If so, how can I back it up?
Thanks for your help

Here is a GUIDE to unlock the bootloader and root your phone
Thanks, LS.xD
This was all I needed, I've found a CM11 Rom in the Modaco forums, hope it works well. Just got to wait until I get the phone
Okay, so I downloaded the latest nighly of the ROM, but it appears that CM11 is not very stable and has many problems with SystemUI (statusbar) and other things. Aren't there any ROMS for the Y300 on XDA? Also, will I lose my network connectivity if I do the wipes (data,cache, dalvik cache)?
Again, thanks for all your help, I appreciate it
EDIT: Found CM10.1 here in XDA but it redirected me to Modaco, however it is quite stable, downloading now. So which wipes do I have to do, in order to get everything smooth? Also, as I said will I lose my network connectivity or IMEI if I do these wipes, or I can do this without worrying

Will this custom ROM unlock the phone?
I have bought this phone from T-Mobile, but chose the wrong option when buying (not the unlocked one) and now the only way I could find to unlock the phone would be paying for the network unlock code (around $30).
Would anyone know if by flashing this ROM it will unlock the phone to use another carrier's SIM card?
Any other option on how to unlock the phone using another method would also be greatly appreciated.
No, the custom ROM will not unlock the phone

Already found the answer to my own question. I flashed the custom ROM to the locked phone and tried to place a SIM card in it, but still get the Invalid SIM card message and it requests the network unlock code.
I can also say that kitkat metropcs twrp backup works on the Univision variant and it works with a sim card from another country, thanks!!
EDIT: This ROM won't unlock your phone, this is another part of the device that is not dependant on the rom, to unlock you'll need an unlocking box like z3x, or pay for an imei unlock code, mine could be unlocked with 13 dlls from unlockscout, samsungs made in china.

Phone is now unlocked and updated to Kit Kat
Indeed, the part of the phone responsible for the network lock is not messed with by the custom ROM or the update to Kit Kat method, but I actually found a way to unlock without a z3x box or having to buy the unlock code online.
The phone I was trying to unlock is a friend's phone, but I have my own phone and it was bought already unlocked, and is the same model. The trick here was to find out that the network code lock was part of the EFS partition. I made a full backup of my phone (unlocked) through TWRP and restored it in my friend's phone. It did unlock. Then it was just a matter of resetting to factory defaults and performing the procedure to update to Kit Kat and it now is unlocked and updated. \o/

Heres my question, if the phone is from tmobile how did you get kitkat? Unless you did it with the METRO backup
cm version
Thanks. Looking forward for that CM ROM.
One potentially noob question: cm11 is based on 4.4 while this device is officially still 4.2.2. Would that be OK?
Yes thats why people started making xustom roms

I read somewhere that someone was trying to download KK update from T-Mobile this could be just a 4.2 update or they could be pushing it. Maybe new lights are shipping with KK as well who knows

There are many phones who are stuck on outdated firmware. Gnex, nexus s, htc mytouch 4g/slide all running kit Kat. Many many more examples. The Roms may not be stable due to various reasons (no source, outdated hardware, lack of Dev etc) it is possible
Is there a test that will show if a phone is locked or not. I hosed my efs partition a while back and had to format it, change permissions, and reset to factory default to get my Galaxy Light to boot. Does that mean that my phone is unlocked?

Yes, I did it with the MetroPCS backup. Tried to flash the kernel of KitKat straight from the T-Mobile system on 4.2.2 but it did not work.

The work I'm doing is based on the metro PCs released kernel source and device files which are 4.4. They have the same everything just different bloat from carrier.

I believe you are looking for an app that is able to test if the phone is network locked or not. I do not know of such an app. The basic test you can do is try to insert a SIM card from another operator and see if it allows it or displays the message of it being an invalid SIM, asking for the network unlock code. And you don't need to buy another SIM, just borrow a friend's, it will only take a minute...
Thanks, that's my little problem in that I don't have access to a micro or mini SIM like the one in this device.

Greetings XDA Zombies!
Got the T399NUVUANH1 working on my T-Mobile T399. Having issues getting ViPER4Android FX drivers to work. Have BusyBox Pro and seems that it wont install property. The ViPER4 2.3 version says the drivers are installed but actually not working, and the ViPER4 4.x version I keep getting the drivers failed.
Appreciate any help.
Footnote: X Tether works!
Bummer. Think TMO watching XDA and clamping down on whatever loose ends they can bind.
Metropcs GL
Will this work on a galaxy light with Android 4.4.3? Does the build have to be the same?
