I read through many threads and have followed the official Sony bootloader unlocking instructions. I have requested and received the unlock code from Sony via email. I have downloaded the inf file and placed it in the correct folder in Android SDK (which I also updated). But I am cannot access fastboot mode, I hold down Vol + and plug in the USB cable but the device shows a red led and goes into charging mode. Also the PC never prompts me to install fastboot driver it simply loads the SP as Sony mass storage device (in device manager).
I have read that some people seem to think that the SIM lock affects the ability to access fastboot but this SP is SIM unlocked. Sony's official guide to unlocking the bootloader says I need to access fastboot mode to enter the unlock code but how can I unlock the bootloader if I can't get into fastboot mode?
hmmm... don't know really... i once entered fastboot mode by mistake, while trying to root stock rom. wasn't reading instructions and put device in a fsatboot mode instead of debugging... was on stock rom so don't know if custom rom would let me do that. should check myself... if anything i know it is possible to get me that blue light shining.
To enter fastboot mode in Xperia SP just power down the phone and hold down the volume up key while pluging your phone into your pc
If you need flashmode do the same thing but with the volume DOWN button held down.
I´ve got the same problem. I can´t enter in flashmode neither in fastboot mode. I´m on windows 8 32bits and I installed the .245 Deodexed ROM with a problem on root and without CWM. I don´t know what to do now, please help me.
As I explained in the first post, I understand how to access fastboot mode (and flash mode). I got root and backed up the TA partition, the stock apps (from 1.257) and backed up the stock ROM. Then, after I wasn't able to get into fastboot, I have installed CWM for LB and flashed a custom ROM based on 2.245. I am able to enter flash mode but not fastboot. As I said before, the phone is SIM unlocked but is acting like it came from a carrier, with locked bootloader and fastboot disabled. How can Sony disable fastboot? I don't get it. Any one want to take a guess how long I will have to wait until some clever dev finds an exploit?

Sorry for that i dont think that it is your computers fault because you enter fastboot (and flashmode) using your mobile phone NOT your PC
So i would roughly assume that this is a Rom bug or something in the flashing proccess went wrong.

Thanks for trying to help, but I understand that flashmode and fastboot are accessed using the phone. Actually the phone needs a piece of software like flashtool to keep it in flashmode otherwise it drops into charging mode. I didn't mention my computer so I don't know where you got that from.
As I explained, I am unable to access fastboot with stock ROM (1.257) and a custom ROM (based on 2.245) so it can't be a ROM bug or the flashing process having gone wrong.
if it's not too much of a trouble for you, go and flash .245 stock, than .257 stock kernel only. like you are trying to root it for the first time, complete rooting procedure, and than proceed on to installing CWM, but instead of connecting device in debugging mode to install CWM, try and see if you can put it in a fastboot. this was exactly the moment when i accidentally put mine SP in fastboot. of course, i'm not saying to go ahead and install anything if you score, but only to confirm if you can put your device into a fastboot mode since installing anything without CWM will likely soft brick your device.
Same problem here, i can't do anything using flashtool after flashed 2.245. I did with SUS, maybe is some flashtool issue.

It may be a flashtool problem you are right because 2 incidents with different Roms that both use flashtool to flash those roms.....
its pretty much self explenatory.

Interesting. Ok, I've read up on the process. So I use the various stock .ftf files and flashtool with the phone in flash mode? Bear in mind that kernel didn't allow fastboot when I used it with the stock .257 ROM the device came with. If I do it, I will nandroid backup first, of course, but I think I remember reading in one thread that someone managed to soft brick their XSP doing this very thing.

that's why you need to complete rooting procedure. root stock 1.257 kernel, than back to stock 2.245 with root preserved, and before you would install CWM try to put device in a fastboot mode, this assuming you still have a UB.

have you tried to boot into android, open a root terminal and type
exec reboot bootloader
that should bring you straight into fastboot

All that happens is that the terminal session ends and closes (not FC) the terminal app. Using the same command via adb just does a standard reboot.
i just placed my in a fastboot mode, no problems whatsoever. do you have drivers for the device installed? you will find these in flashtool installation folder.

Yes. The fastboot_with_android_usb_file.rar package specified on DooMLoRD's bootloader unlocking/relocking appears to have been removed and there are no new links in that thread. So, I found and installed the drivers included with the flashtool. But it seems to be the device that is the problem. It is acting like a carrier locked model. I am rapidly starting to believe that this one has a locked bootloader.

Hi, I have some similar issues. I've also been flashing some stuff and whenever I try to go to fastboot it just boots into CWM. Very annoying to say the least. The dark blue light goes on when i hold down volume up and for a short moment I see the fastboot driver installing on my computer. But before it completes it's already in CWM.
Not sure what to do from here on wards, maybe some advice on which kernel to flash? I am pretty sure the latest kernel I flashed is the .254 root kernel from doomlord.
Ps. I really would like to flash CM when it becomes available as nightly :angel:
Thanks in advance!

I had already installed cm10.1 jb for my xperia ion.
Now i tried to install cm11 kitkat for my xperia ion.
Every thing is gone good.
But now got stuck up with a problem.
fast boot mode is active only for 5 seconds while connecting my xperia ion to System with flash tool.
help me to do the need ful.
Guide me to download compatible drivers and flash tool for fast booting process.
If you have UNLOCKABLE bootloader, then you dont have a FASTBOOT mode on your phone. Its just pure luck. some phones dont have it... kind of a sony crap... I also happen to be one of those LUCKY ppl. no unlock, so stuck with Stock kernel forever.
When you connect your phone to Flashtools in FLASHMODE...
See for a string BOOTLOADER: NOT_ROOTABLE.... it means you belong in the lucky group...
If it says rootable, then you're doing something wrong.
Pardon me if i read something incorrect. i skimmed through all the posts before posting.
My C6903 in LP 5.1.1 doesn't take photos (or videos) when the app tries to focus. Without focus enabled (using other app) it goes perfectly. I've tried with 14.6.A.1.236 Customized BAL, 15.5.A.0.242 Movistar AR and a few more, all obtained from XperiFirm.
I tried pushing that "4k and timeshift" .zip which I read could fix the camera but no luck.
Curious thing is that Rooting Status shows "Unknown", I don't know if this could be related or not. I bought the phone on eBay (used) and I couldn't tell you if it's been unlocked or not.
But I know that everything can't be messed up because in JB 4.3 (14.2.A.1.136 Generic BAL from XperiFirm) camera works well, and Rooting Status shows "Bootloader Unlock Allowed: Yes"; And in KK 4.4 (updated via OTA from mentioned JB firmware) camera stops working in the same way but Rooting Status keeps on "Bootloader Unlock Allowed: Yes".
What could I try? I think I've already read everything related to the Rooting Status Unknown and Camera freeze problems in this forum and still have no clue (even in other Xperias forums too).
Thanks by the way
PS: Yet I didn't tried unlocking bootloader just because it may bring more problems, but if needed I would do it in a blink

This is definitely a bad way to troubleshoot your problem, but go ahead and make yourself a backup of your phone's TA partition and unlock the bootloader of your phone. As long as you made a backup of the partition, the DRM keys will stay intact when you re-lock the bootloader; thus, you won't lose any exclusive Sony features upon restore. Make sure you have the proper adb and fastboot drivers before you begin.
Backup TA partition: http://forum.xda-developers.com/showthread.php?t=2292598
Unlock bootloader: http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Flash any custom ROM (don't flash the Marshmallow ROMs) found in either the Android Development or Original Development page for Z1. You can also flash a modified Sony ROM in the Android Development section that has mostly all of the features in Sony's stock ROM plus some additional ones picked from CM/AOSP ROMs. Either way, if your problem is fixed, then it's a problem with the FTFs you flashed. If not, restore your TA/DRM keys (it'll re-lock your phone's bootloader) and report back.
Good luck fixing your problem!

Install proper drivers for fastboot. Power the phone off completely, then while plugging your phone into the computer, hold the top volume button. You should be able to enter fastboot if fastboot drivers are properly set up.

Is there a way to know if fastboot drivers are properly installed? I've checked and reinstalled them about 5 times, but I'll try again tomorrow just to be sure I'm not missing anything.
I don't know if there are different drivers but always installed the flashtool ones. By the way I'm running Win10 but also tried in Win7 and no luck.

If your computer can successfully detect the device and output it's serial number when you input through command prompt:
Code:
fastboot.exe devices
you'll know that fastboot is working and drivers are set up correctly. If you look at your device LED, the LED will be lit blue. Remember: you need to already have downloaded and installed the applications through the executabe in the adt folder to get the fastboot and adb applications.

Right, I know what that command line does, but that will work only when drivers are properly installed AND phone is detected. What I believe is that there are some kind of problems with the phone to not go into fastboot mode, so it wont be detected at fastboot, always in flashmode.

What is the adt folder? You mean adb or the obsolete Android Development Tools (now Android Studio)?

Just download the S1 driver file through the link I provided earlier, install, reboot computer, then run the same command as I told you from my previous post: if it outputs the serial number of your phone, then you're fine; but if it doesn't, post back. As long as your computer can establish a basic connection to your Z1 (PC can see it in flash mode, could access it somehow), your phone is capable of fastboot.

I think I've followed everything right but to be clear I'm gonna explain what I've done so far:
- Installed Android Studio (I believe it comes with those "just the command line tools").
- Installed Flashtool's driver (same as the DoomLord link you provided, even a later update than that link), also did that thing about "Disable Driver Signature Enforcement" because I'm on Win10 64bit.
- Always checked by cmd command line "fastboot.exe devices", I've never get any error (so cmd always detected it as a valid command line) or any other cmd print.
- I have a TA backup but after I made it tried to unlock bootloader but no luck. Anyway, just restored the backup and only sign I got is "Upgrading NFC firmware" or something like that after booting, the "NFC upgrade" went well but still no fastboot access.
---
- When I plug the usb + press volume up button to try get fastboot mode, phone's led goes red then green then it goes off and in flashtool I get flashmode with no led on.
---
By the way, I have an Xperia SP and already unlocked bootloader so I pretty know how it should go. Having no problem with it accessing fastboot or even locking or unlocking on the XSP.
Because of this and baseband problem, I can't stop thinking motherboard is messed up.. But anyway, whatever you think I could try just let me know.
Hey guys,
This is a bit of a long one so please bear with me...
I have an EU EVA-L09 which was running EVA-L09C432B166 unrooted and with a locked bootloader. I decided to unlock it which I did successfully (Fastboot was showing both Phone & FRP as unlocked) and flashed TWRP on to it as well as BETA-SuperSU-v2.65.
After a few days with my stock email app not working and Battery Settings unaccessable since rooting (not to mention the warning message every time I booted my phone) I decided it wasn't worth it and wanted to remove it all and go back to stock. I was struggling to find a stock rom due to being impatient and just removed root via SuperSU app on my phone.
I found a stock recovery image which I tried to flash on to the phone using the BAT file (PASO 3 VOLVER A RECOVERY STOCK) which didn't seem to work. I also tried to do it via cmd line and was faced with "FAILED (remote: Command not allowed)." I also noticed that FRP was showing as locked now in fastboot. I did unlock it using DC Unlocker but it's still displaying as locked (after some research on the forum this seems normal.)
I tried to update to Nougat 7.0 by Wiping in TWRP and then installing Update.zip from another thread on this forum. This worked great but stupidly I forgot to install the EU pack zip which accompanied it before rebooting. Unfortunately this has now installed a limited version of Nougat on to the phone whilst simultaneously removing TWRP so I can't install the other zip.
I have tried to install the other zip and some old firmware using dload method but I always get stuck on 5%. I have also tried flashing TWRP again but I am facing the same , ""FAILED (remote: Command not allowed)" error. The error is also displayed when I try to re-lock the bootloader. The bootloader is definitely unlocked as I have checked with cmd line & the warning message is still being displayed on booting up. I have USB debugging enabled but am unable to enable OEM Unlock due to the option being greyed out (seems to be the case when FRP is unlocked.)
I can't do any updates using 3 button technique they all get stuck on 5%. I can't submit any flash commands in cmd.exe without getting the "command not allowed error."
There is a bit of hope because I can boot in to Nougat but it's very limited with no apps and no keyboard.
Can anybody help?

Ok just for completion and anybody who is having the same issues as I have had with the same or similar model of P9, this is how I solved it (after a day without sleep and a couple of migraines). Please note this is only to be used if you have exhausted all other, free options on this forum as this is slightly risky and costs money. It's a last resort.
What you'll need:
- HiSuite installed but closed on your PC
- USB cable to connect phone to PC
- DC-Phoenix with an account with 15 credits (15 Euro)
- The DC-Phoenix guide opened at "Method 2"
- Firmware .img file from their database by clicking "Enter Support Area" button in DC-Phoenix (EVA-AL10_M00A056_Factory_firmware_Global_Nonspecific_Android_6.0_EMUI_4.1.dgtks)
- Stock firmware as an .app file on an SDCard in a folder named "dload" (I used EVA-L09C432B182 (UPDATE.APP))
Method:
1. Copy the official stock firmware .app file to your SDCard inside a folder named "dload".
2. Remove SDCard & Sim Card from the phone.
3. Put your phone in to Fastboot (Turn off phone, hold volume(down), insert usb cable).
4. Load DC-Phoenix and select Fastboot mode.
5. Click "IMG Files" tab and locate the .dgtks file using the "Config or recovery file:" field.
6. DO NOT uncheck the boxes next to "Not erase NV" and "Not erase oeminfo" as this will delete your IMEI and other information completely.
7. Click UPDATE and wait for it to fully finish (you may see an error regarding FBlocks but it should still go on to complete).
8. Once you see it is completed, disconnect phone from PC and restart the phone by holding the power button.
9. This should load you in to a very basic firmware (it may take one or two reboots to achieve this).
10. Insert your SDCard with the newer, official, stock firmware that you want on the phone in to the SDCard slot WITHOUT SimCard.
11. On your phone home you should see an icon named "Upgrade" or "Upgrade/Update Phone" on the first page. (I've forgotten the exact name of the icon but it will be obvious to you).
12. Click that icon and it should go ahead and install the firmware .app on to the phone off your SDCard.
After following the on screen instructions you should now be back to stock firmware. I recommend re-locking your bootloader now using fastboot and your unlock key if you are trying to do so. If you go on to update to Nougat 7.0 before locking your bootloader back up you won't be able to do so without downgrading back to the same firmware that was on your phone when you originally unlocked it.)
Hope this helps somebody who is stuck and exhausted every other avenue with nothing left to lose.

I had a similar issue after doing this :- unlock bootloader...root MM....Upgrade to Nougat...root...Rollback to MM...root...Upgrade to Nougat.. borked!!!
I was left with a phone that only booted to bootloader and no recovery or possibility of flashing with dload worked.
Luckily DC Phoenix got it into a usable state where i could enter erecovery and flash Nougat again. Seems the backdoor method they use to load the OS, at least at a low level, is very effective!
There's probably a lesson here, but I've never had a phone so easily bricked....
Thanks :good:
Peace

What you'll need:
- HiSuite installed but closed on your PC
- USB cable to connect phone to PC
- DC-Phoenix with an account with 15 credits (15 Euro)
- The DC-Phoenix guide opened at "Method 2"
- Firmware .img file from their database by clicking "Enter Support Area" button in DC-Phoenix (EVA-AL10_M00A056_Factory_firmware_Global_Nonspecific_Android_6.0_EMUI_4.1.dgtks)
- Stock firmware as an .app file on an SDCard in a folder named "dload" (I used EVA-L09C432B182 (UPDATE.APP))
Method:
1. Copy the official stock firmware .app file to your SDCard inside a folder named "dload".
2. Remove SDCard & Sim Card from the phone.
3. Put your phone in to Fastboot (Turn off phone, hold volume(down), insert usb cable).
4. Load DC-Phoenix and select Fastboot mode.
5. Click "IMG Files" tab and locate the .dgtks file using the "Config or recovery file:" field.
6. DO NOT uncheck the boxes next to "Not erase NV" and "Not erase oeminfo" as this will delete your IMEI and other information completely.
7. Click UPDATE and wait for it to fully finish (you may see an error regarding FBlocks but it should still go on to complete).
8. Once you see it is completed, disconnect phone from PC and restart the phone by holding the power button.
9. This should load you in to a very basic firmware (it may take one or two reboots to achieve this).
10. Insert your SDCard with the newer, official, stock firmware that you want on the phone in to the SDCard slot WITHOUT SimCard.
11. On your phone home you should see an icon named "Upgrade" or "Upgrade/Update Phone" on the first page. (I've forgotten the exact name of the icon but it will be obvious to you).
12. Click that icon and it should go ahead and install the firmware .app on to the phone off your SDCard.
After following the on screen instructions you should now be back to stock firmware. I recommend re-locking your bootloader now using fastboot and your unlock key if you are trying to do so. If you go on to update to Nougat 7.0 before locking your bootloader back up you won't be able to do so without downgrading back to the same firmware that was on your phone when you originally unlocked it.)
Hope this helps somebody who is stuck and exhausted every other avenue with nothing left to lose.

Vou are the best, yeppie !! You save my live..because I have not damaged myself and tyrannized my family as it would have been possible, if you had not helped :good: Huawei P9 Plus Dual-Sim
Thank you so much!!
I can't believe how much I have scoured through the interwebs untill i came to your post.
I even went through all other DC-Unlocker options including the HCU client, which I burned another 19e on. -_-
I know you posted this over 3 years ago. But thank you for doing it! <3

Dear DCStreamer,
I tried to follow your procedures with my Huawei tablet but don't work: where I wrong?
I have successfully unlocked the bootloader and managed to install TWRP 3.1.0-3 but that's about it. I cannot install any other TWRP version but the one I mentioned. I tried installing Magic Rainbow custom ROM but it doesn't work properly (apps are super slow, entering developer settings makes the settings app crash, can't set a password etc.). So with that I can at least access the phone interface with limited options. Developer settings crashes when I choose it; if I can get through then I can't enable USB debugging, it keeps turning itself off right as I enable it. I can't use update function so I have to use 3 button installation, which randomly fails to work very often. Due to this I haven't been able to install any updates.
I kinda gave up on rooting already, I just want to get my old firmware back at this point but I can't even do that. SRKTools stock marshmallow recovery doesn't work either. It's as if TWRP 3.1.0 has taken over everything. On the rare occasions that I managed to get EMUI update via 3 button installation it would say that the update doesn't match the current version (or something like that). I tried using recover for b378 and managed to run the 3 button update but it always gets stuck at 5%. It gives up after a while, tries booting twice and then goes into eRecovery screen. My bootloader PHONE unlocked text is in red if it matters.
I've been actively trying to fix this for the last 11 hours (yes I'm not exaggerating at all). Please, PLEASE someone help me out with this!
I've also tried using the unbrick tool of the latest SRK Tool 2.0 for b378. It goes flawless, phone restarts and does a factory wipe but then doesn't boot after the Huawei screen. It tries booting twice and then it goes into eRecovery screen. Have I ruined some hardware here?
It seems like 3 button upgrade is my salvation and it doesn't work. Many times I hold it down, I get a slightly different screen but it again hangs at booting text. I managed to flash all recovery, boot and system image files and got the installing update screen in my b378 update, but it hangs at 5%. I couldn't even manage to get the installing update screen for common b136. Also when I try to flash system.img I get an error with flashing system which is FAILED (remote:sparse flash write failure).
First at all: The Magic Rainbow custom ROM is based on B383 so it wont work on B378 firmware thats your fault here.
Just flash the rollback package (find it in my signature) and after this flash B383 or if it not work start with B136. U have to do all with the dload method.
Fast solution?
https://forum.xda-developers.com/p9/development/p9-moonlight-rom-v1-0-b378-stock-t3567223
flash the B378 version. probably your problem is solved by this.
I'm very well aware that Magic Rainbow doesn't work with b378. That's probably the reason I have those issues with it. But it's the only way I can access the phone's interface in case I need to use it for a fix.
I tried flashing b378 already multiple times, without rollback and it did not work. Is it safe to use the rollback though? My oem is c432, would it create any issues to use that? Should I flash c900 oem first or can I go with the rollback right away? I literally cannot install any stock rom without having frozen/looping bootscreen atm so I can't complete any step that requires me to do that.
I've also tried flashing b136 plenty of times already. I can't even flash the system.img. I can't flash the system of any of the b100 series.

u tried the rom i mentioned?
it is safe to use the rollback package. any firmware after will retrive your oem to c432. so you dont need to flash the oem info package.
1. flash rollback package via dload (watch out to have only the UPDATE.APP file in dload folder)
2. flash B383 via dload (2 files need to be flashed!)
3. flash special SuperSU_for_EMUI5.zip
4. have fun
again if u can boot magic rom then you can flash and use Moonlight rom v1.0

I cannot flash rollback using 3 buttons method. I see the "your device is booting now" text and then it goes to TWRP menu. Nothing happens. This is what I mean with 3 button method not working. Every single update fails probably because of this. Is there anything else I can do to flash it?
I've also tried flashing b378 and then doing the rollback. Still doesn't work: It hangs at 5% as it did with the b378 update.
Also, is there a special way of flashing those 2 files of b383? Is it just one after another? I doubt I can flash them at the same time since they have the same name.
YES IT WORKED! Thank you the rollback actually made the difference. I had to go for b136 and then upgrade manually through there with the stock OS though. And I believe rollback changed the status to LOCKED instead of RELOCKED. And I was a complete moron for I couldn't do 3 button update because my cable was still plugged in. I had a moment of epiphany when I noticed what the symbol actually represents. It was like discovering who Keyser Soze was lol. Let this idiocy stay here for there might be others like me; this way they might fix it without embarrassing themselves like I did.
Glad it worked for you.
Next time just read the threads in this forum.
There are several toturials how to flash the p9 the right way.

Every time I try to flash, with 3 buttons method, it puts me "software install failed"
I tried to flash official rom with twrp but he can't finish the process.
I tried to flash custom rom. When I want to boot, he bootloop.
Hi,
I am at a complete loss and going round in circles. My phone has bootlocker unlocked message at moment. In adb fastboot devices finds the phone, but the SRK tool fails to find it sticking on 'waiting for phone'. I tried to flasg the Huawei rollback but that fails (presumably due to being unlocked). I cannot relock via fastboot as that gives 'remote: command not allowed' error.
Update
- I have just checked fastboot - it says Phone Unlocked & FRP Unlock.
- Next I used Huawei Update Extractor to get boot, recovery, cust & system img from the "HUAWEI_P9_Firmware_EVA-L09_Andriod 6.0_EMUI 4.1_C432B166_United Kingdom_Channel-Others" Package.
It seems I still cannot boot and device still says unlocked etc..
Update 2 :-
Copied the dload/update.app file from the HUAWEI_P9_Firmware_EVA-L09_Andriod 6.0 zip. Managed to get it to start installing, only to get Software Install Failed msg. However reboot let me start the phone. So currently have Build No: EVA-L09C432B166 on.
At this point I just want my phone either back to initial factory state or able to flash roms, whichever is easier to get to. Any help greatly appreciated. I've been getting nowhere following guides I have found, so would really appreciate some help here.
Thank You

Ok first of all, using TWRP back up everything you have there (backing up SD card isn't really needed unless you plan to wipe it too). Then, using TWRP again just wipe everything but OEM and SD card (external storage). Then, create a folder called "dload" in the main SD card directory and put ONLY the update.app in it (use the stock b136 as suggested). Now you need to flash a stock recovery using bootloader again. Just use the Huawei Update Extractor and get both recovery.img and boot.img from the rom that you're using to flash (in this case b136). Put them in the same folder as adb. Run adb cmd, write commands "fastboot flash recovery recovery.img" and then "fastboot flash boot boot.img" and finally "fastboot reboot". Quickly unplug your usb cable and use the 3 button force update (Vol Up+Vol Down+Power button all held together and don't let go until you see the update start). It should work without a problem if you had managed to wipe everything using TWRP. If it still doesn't work you could try deleting OEM info as well and flashing a new one (c432) which you can find on the forums. Back up is important in case it still doesn't work, you might need them to undo things.
If it boots, it means you've learned how to do it and you can probably unbrick it as much as you want haha. You can update to Nougat (7.0) and EMUI 5 using Huawei Updater 2.0 along with HiSuite, there is a guide here on the forums to do so by updating to b182 then to b360/b361>b378>b383 which I was unable to find for now. After that you can install a custom rom without an issue. I figured I wouldn't mess with it anymore but frankly it's likely that you are just soft bricking by skipping something very simple and failing because of that unless you went ahead and did things that you are explicitly told not to do so. If you end up having it unlocked/relocked might as well try and get a custom rom really.
If the update gets stuck at 5% or you have the icon of a usb cable end with a lightning on it your mistake is that you didn't unplug it. If the update keeps failing without these it's likely that you're using the wrong firmware and you could try using another one (FULL+PV+MV ones if you're going for a higher one). Or you could try to follow the rollback and then the update as I did. if you do the rollback then the update, your phone might get a LOCKED status again (yes not relocked).
If you are missing something or you think you have a stupid question and too shy to ask it here just PM me.

So you're saying that you're able to boot your phone on stock b166? Then update it to b182 first. I had to keep pressing the check update for a while before it popped up. I was busy at the time so I didn't mind the wait time but I bet you can do it faster forcefully, got to be a guide around here somewhere. Here is the guide to update it all the way to b383 from b182.

I'm on B166 currently. Phone tells me it has update for B182, on reboot I get the device unlocked message and it sticks on 'Your device is booting now'.
Also tried Huawei updater....that sticks at 'Listened on Port 41279'
Thanks

Getting the device unlocked message shouldn't indicate anything, only that you didn't lock it again. It might be that you didn't install your current rom correctly. You could try flashing TWRP, backing up everything and then wiping all of it f. It means you'll be romless for a while but worst case you can recover what you backed up with TWRP and then flash it with a stock rom again. There are guides to flashing everywhere and I've made my own guide here. I can't really give you advice on your situation since I haven't ever been there. I just dabble with these things, so I can't really find a solution for everything.
You are connected to HiSuite while running Huawei Updater right? It needs to be able to see your phone (usb debugging on or HDB mode) and set to usage via proxy.

Run HiSuite. Make sure your phone is connected to it. Top right you'll see 4 buttons: 3 horizontal stripes, minimise, full screen and X. Press 3 stripes one and choose settings. In the first tab called General under the 4th section you'll see Proxy. Enable it and enter 127.0.0.1 for address and the given listening port as the port. Leave the username and password blank. Press apply. Then you probably have to choose the system upgrade from the main screen of HiSuite. I don't recall exactly but this is about how it goes.

I managed to flash B360_update.zip via recovery instead. I also have a B360_update_data_full_hw_eu.zip but not sure what that is for.
Hello everyone, it's my first time writing here, but I’ve tried everything, searched everywhere, and am desperate for help.
I screwed up big time while trying to flash a custom rom on my nem-l21, as I successfully did before with my xiaomi... So what I did:
I managed to unlock bootloader with dc unlocker. Then I got stucked flashing twrp with adb tools. Everything was looking to be fine, no error messages, “flashing successful”… But, I was never able to boot into flashed twrp. Always got stuck on “your phone has been unlocked blah blah. Your device is booting.” It never booted, not in twrp, nor in stock recovery. I tried different versions of twrp from different sources, always same result (flashing successful, booting into recovery not). Booting into the system was fine. And then I made that horrible mistake. Oh, how I wish I didn’t!!
I read on some website, that you are supposed to flash the twrp as boot.img, not as recovery.img. Seemed illogical and stupid to me, but in the end I tried it. Of course, this just bricked my phone, with no possibility to boot. After hours of googling, installing, trying and crying, I managed in the end to flash back stock boot.img. But at that time, I didn’t know my build number (b359), and I flashed boot.img b351. So now I have a phone which boots into the system b359 with boot.img b351, but with lot of errors.
- developer options, security options, display and factory reset option doesn’t work and just crashes. Therefore I am not able to flash the correct boot.img b359 or anything else at all from pc, no way to enable usb debugging and oem unlocking. Adb devices → nothing. I am able to use fastboot (fastboot devices sees the phone), but when try to flash something, I get error “command not allowed”. Also I can’t enable unknown sources installation, which bothers me a lot. And I can’t make factory reset to restore the crashing settings. Also I can’t change display timeout, and original 30 secs is super annoying.
- I am not able to uninstall even apps installed by me, always just restarts system UI and app stays.
What I tried so far:
- flashing correct boot.img from pc, not working because of dev options crashing
- go into recovery, but stock one is overwritten with unfunctioning twrp, always just get stuck on “your phone was unlocked blah blah… your device is booting now”, but it never does, have to hard reboot
- go into huawei erecovery, which is working, but when I try to resolve problem from there, always ends up with errors and crashes
- connect to pc and use HiSuite, system recovery tool here always says “no problem detected”
- updating to b361 through system update settings, always crashes on 5% and sends phone into “your phone was unlocked blah blah… your device is booting now” error
- downloading the proper b359 as and update.app file, put it in dload internal storage → same error during update, put it in dload sdcard → same error, no matter which way I use to start the update
- boot into twrp or stock recovery.img through fastboot without actually flashing it, anyway error “command not allowed”
- do factory reset or update through dial codes (i.e. *#*#123456#*#* …), nothing worked
My pc is windows 10, all drivers up to date. Using powershell as an admin. Am an idiot for not making backup of the phone before I started...
So, now I have more or less functioning phone, but I can’t uninstall any apps at all, can’t install from unknown sources, can’t do nothing from pc, can’t make any update, and lot of important settings keep crashing.
I can use the phone like this, but if somebody could think about some solution for this ****ed up situation I got myself into, I would be grateful to him/her for the rest of my life.
Sorry for a long post.
Thank you in advance and have a nice day
I think using Hisuit will help. Enter Fastboot and connect ur phone to ur computer and use system recovery toll
