Unlocked/Rooted my stock One but it did not wipe? - ONE Q&A, Help & Troubleshooting

Hi Guys,
I was running stock CM12S version: '12.0-YNG1TAS17L' which i got with the last OTA update. I believe it is the newest CM12S update.
The phone had never been unlocked or rooted previously, 100% stock from new.
I decided I wanted to unlock the Bootloader/install TWRP & Root.
I followed the One Plus One 6.0 Toolkit.
I have heard time and time again that once you unlock your Bootloader that your phone will wipe your current OS, However, this did not happen to me.
After unlocking the Bootloader and installing TWRP I rebooted and I got the Android is optimizing screen, my phone booted into my normal OS, nothing was wiped. Exactly how I had it in stock.
I assumed I screwed something up and did not unlock the Bootloader but I can confirm that running the "fastboot oem device-info" command I get the following:
...
(bootloader) Device tampered: true
(bootloader) Device unlocked: true
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
OKAY [ 0.010s]
finished. total time: 0.011s
I'm a little confused, Is this a new feature in CM12S? Where you don't need to wipe to unlock bootloader/Install Recovery & Root?
Right now I have the message above showing the bootloader unlocked, SuperSU installed and working (Also checked with Root Checker, showing root access)& TWRP is working 100%
Appreciate any help.
Cheers

Okay, so what is the issue? Because everything is working as I see. Unlocking the bootloader never wipes your OS, maybe does a factory reset (on Nexus series) or removes proprietary software (Xperia line). When I was unlocking HTC devices and OPO the OS, DATA remained untouched.

No issue, im interested to know why it didn't perform a factory wipe, that's all.

So it didn't wipe any user data? Like apps and the internal storage? It's never wiped the system but it usually does wipe user data. It's possible that the bootloader was already unlocked, did you purchase it directly from OnePlus?

Yeah, didn't wipe any user data at all.
It's the chinese version purchased from a wholesaler who flashed cm11 33R (it had color os)
Good point, maybe it was already unlocked.
Thanks for your reply mate.

It was definitely already unlocked then. The only way they can get CM onto the Chinese version is by unlocking the bootloader.

Stuck in fastboot, locked bootloader

In a stupid attempt to try to root my Moto G, I followed the instructions here up to step 6, rebooted, and was greeted in fastboot with a "failed to validate boot image" message. I have tried flashing a new boot image but I get a remote failure saying "Preflash validation failed", presumably because the phone's bootloader is locked.
The phone is from Cricket/AIO/ATT or whatever and does NOT qualify for bootloader unlocking.
Is there any way to fix this, or have I bricked my phone?
If you still have a warranty, USE IT. (Your warranty isnt void until the bootloader is unlocked, and if the warranty period hasnt expired yet)
1. Try to enter stock recovery and Factory Reset the phone.
2. Try to do a tethered root and then try unlocking the bootloader. (This is probally why the root failed) (If it does not qualify, try using sunshine: http://theroot.ninja/)
3. SKIP THIS STEP IF YOU DID AN OTA UPDATE TO 4.4.4 - watch this video: http://youtu.be/laU6NQ0LxR0
4. Try to enter stock recovery and Factory Reset the phone.
5. Flash a custom recovery such as ClockWorkMod
6. Try flashing stock rom with a flashable zip.
7. Try flashing a custom rom such as cyanogenmod

Thanks for the reply. Will definitely look into warranty if all else fails, I've only had the device for about a month.
The stock recovery factory reset doesn't fix the boot image. It successfully wipes everything but it still reboots right back to fastboot.
I cannot unlock the bootloader as it has been locked by the carrier and does not qualify for bootloader unlocking according to Motorola, and it looks like sunshine is a paid service, which even if I paid for I would have to be able to get into the phone to install the apk anyway.
It fails flashing any boot images or custom recoveries with a "(bootloader) Preflash validation failed" error.
To do any flashing you need an unlocked bootloader. Sunshine is a bootloader unlocking utility, its a paid app for a reason, the amount of time the devs put into making an app like that requires payment. You do not need root for installing sunshine as the app will root for you. You need to go to settings > security > and check install from unknown sources. Then download the app and run it. You can just download sunshine to check if your bootloader can be unlocked as at first it will not do anything but run a sieres of compatability tests to see if the bootloader is unlockable. Only then will it ask you for payment. But I highly suggest sending it into warranty and then try the rooting process again, but this time with an unlocked bootloader.

Yes, that's all fine and dandy, but like I said I'm stuck in fastboot so I wouldn't be able to use it anyway. At this point I don't even care about rooting, I'd just like to get my device working.
You do not need an unlocked bootloader to fastboot flash a Motorola firmware image.
You will get a 'Preflash Validation' error when flashing a firmware image older than 4.4.4.
Can you provide more information about your phone. Is it the LTE version? Do you know the exact model number?

It's an XT1032 and was running on 4.4.2. Maybe I tried with the wrong stock firmware, I used "AIO_XT1032_4.4.2-KXB20.9-1.10-1.9_CFC_1FF.xml", which I found in this thread. The version matched the info I found using "getvar all" in fastboot so I figured it was the correct one. The http://sbf.droid-developers.org site seems to be down at the moment so I guess I can try a few more when it comes back up.
That would appear to be the correct firmware. However it would also appear your bootloader is preventing you from flashing it. As I said, the best solution would be to flash the 4.4.4 firmware image for your carrier, however there isn't one at this time.
You can always try flashing the XT1032 EU Retail 4.4.4 firmware image. It doesn't matter where you are in the world, it will should work fine.

Rooting B324 on TL10?

Hello dear forum users.
I am new to Huawei but not to Android, having had (and rooted) devices since Eclair.
Yesterday, (Oct. 1st) I received my TL10 (European version). Looking through these forums I was excited to see that Lollipop had just been made officially available, so before doing anything else I upgraded. As I was on B125SP02 I had to first install B130, then B324.
Now, here's the thing. The rooting guides for Lollipop on these forums are for old stock ROMs and I don't want to risk bricking my new baby. I tried Kingroot, but it failed, so does anyone know if one of the rooting methods here will root B324?
Thanks in advance.

I had to unlock first, which involved various running back and forth to find the unlock page on the HUAWEI site, then finding SN, IMEI and product ID. But I got there in the end.

Well, I spoke too soon. TWRP detects that the phone isn't rooted and proposes swipe to root. I did it and there is a small screen that flashed too fast to read, then the phone reboots, but unfortunately with out being rooted.

Yes I discovered that too after hours of struggling. Now I'm rooted and flashed back stock recovery. First time in these things and I feel proud I didn't brick anything [emoji13] After days of reading everything looks super clear I can root anything now [emoji41]
Still waiting for working xposed version though...
Send from Mate 7 using tapatalk
I got the Bootloader Unlock code and I unlocked my Mate 7 using the command "Fastboot oem unlock <code>" and it showed "done". I repeated the command and it showed "remote: already user unlocked", which convinces me that the bootloader is finally unlocked.
However, when I tried to flash TWRP recovery using "fastboot flash recovery twrp_2.8.7.0_mate7_5.1.img", I still get the same error "FAILED (remote: image verification error)". I have checked the XDA pages and the TWRP version seems to be right, as I used the link (https://basketbuild.com/devs/asyan4ik/hwmt7_l09) given on this post only.
Sequence as follows:
Fastboot Flash Recovery twrp_2.8.7.0_mate7_5.1.img

OKAY [ 1.384s]
writing 'recovery'...
FAILED (remote: image verification error)
finished. total time: 1.404s
Is there a separate TWRP version for MT7-TL10 version? If yes, can someone provide the link, please?
This is very frustrating because it's a great phone and not being able to root is very limiting!
Xposed runs but not all modules as the Huawei theming messes with it.
As for TWRP, I don't like it and only use CWM which is what I have in my Mate7.
I tried various ways including moving back to KitKat. That landed me on a bricked device.
I then went to the website of Huawei to download the rescue package. After lot of struggle, I could get the phone to boot.
The Problem: I have been thrown off to a Chinese KitKat ROM (See attached) and no matter what I do, I am unable to flash an official International Channel ROM. The flash fails every time.
I am looking for a way to move back to either KitKat 4.4.2 or 5.1.1 B324 version of Android 5.1.1 (MT7 TL10 Model). If there is no root for 5.1.1, I would prefer to stick to the latest KitKat ROM with root.
Help.
Back to Stock Lollipop with the help of @acbka
Now need to root it with a locked bootloader. No way to unlock bootloader - even though 'Phone Unlocked' is shown on bootloader screen, yet I can't flash custom recovery through Fastboot.

Root GEM-702L using custom recovery method (TWRP) + SuperSU

Hi
My X2 GEM-702L bootloader us unlocked. I verified by "fastboot oem get-bootinfo" already.
I prefer to root it using the customer recovery method as I'd prior experience using this method on other Android smartphone.
However at the point of flashing the custom recovery I encountered an error:
C:> fastboot oem get-bootinfo
(bootloader) unlocked
C:> fastboot flash recovery twrp_recovery.img
sending recovery (2672 KB)......
OKAY [ 0.609s]
writing recovery

Where did I go wrong ?

Try renaming the twrp to recovery. img. If not download a newer version of Android Tools.
Ok after trying for several hours on various updated drivers, adb tools etc still no success.
I suspected the X2 though stated as "unlocked" it may not be fully unlocked properly for whatever reason.
So I did the "fastboot oem unlock xxxxxxxxxxxxxxxx" one more time and after this I mamanged to flash the custome recovery.
Success finally and I've custom recovery now running ! Thanks.

You know what's funny? When I got my second X2 and went into the Bootloader it said it was unlocked. After I did a factory reset on it, it then said it was locked. I don't know how that could be. Then I used the DC Unlocker program that you mentioned and it unlocked perfectly. I'm glad you got TWRP installed. So TWRP works right? Let me know if you flash SuperSU in TWRP and you have root. Then I'll update my thread to include your version of X2.
Yes....I managed to flash the SuperSU (Beta-v2.49) using the "KangVIP" version of the TWRP.
Now my X2-GEM702L rooted and I can uninstall certain system bloatware and do full backups using the Titanium Pro.
The only thing is to await the 5.11 Android EMUI 3.1 update which is not available yet.

Thanks for the info! Did you try flashing the 703L stock 5.1.1 ROM on your 702L? I'm curious to see if it works.
Flash 703L stock 5.11 ROM ? No haven't tried it.
I wonder whether it will work because the only difference I could see between 702L and 703L is the former has 4 more LTE bands. The other specs looks similar to me.

more info about updates?
is it safe, nothing to do with root/bootloader?
EDIT: DO NOT flash this on official Lineage with Lollipop bootloader, you will end up bootlooping on start, unable to get even into recovery after restart, only possible to get into fastboot which is also pretty useless, since your bootloader is locked
any idea how to recover back without going through flashing all the ROM and everything? is it possible to flash just firmware through fastboot?

I just unlocked bootloader on my Zenfone 3 [ZE552KL 4GB 5.5' Model]
After flashing TWRP and using ROMs based on 9.0, I found that we cannot use
UPI [Payment Interface in India (GooglePay)] in the device!
I tried many methods to flash the stock ROM and lock the Boot loader again, But I cant lock it anyway!
I found a thread by @Saktis_Impreza on this topic but I get:
adb>fastboot oem lock
...

finished. total time: 0.014s
I would like to share an idea which helped me Regain Warranty after rooting
and flashing over several times on the device ZUK Z2 Plus.
I'm not sure if this applies to ASUS devices.
In Z2Plus we can make the device tampered flag to false by flashing an
older Chinese Firmware on the phone using QPST Flash Tool.
Afterwards we can flash the latest firmware to get back to stock with locked Bootloader.
I know I wont get OTA since I unlocked using the OFFICIAL Method.
I just need to Relock the Bootloader.
I Hope someone would Help.
Thank You

Hello anyone pls help
Actually you can relock bootloader by reflashing factory raw, typing in cmd "fastboot oem unlock" and then, with bl locked, reflashing the latest oreo raw.
My tool does it automatically.
