EMEI blank and not charging after update _ Hauwei P8 - Upgrading, Modifying and Unlocking

Firstly to start I did not think this would happen to my phone, I did get the unlock bootloader code but did not try to run a custom rom as yet.
Recently I got the standard EMUI update on the phone and downloaded it, I forgot that I had a old recovery rom in the device and it ran the update but failed. So now my EMEI is lost and I cannot run update plus it does not charge. The recovery mode fails to download and it does not show the USB in fastboot.
Should I send back to supplier? Gees I really dont know to do.

[Q] Messed up my E975... need help... :(

Hello all, on a stock E975 I installed freegee and then cwm, unlocked the bootloader and installed fastboot (i think, there's the start menu if I hold vol+ and power).
The phone shows 'google' and an open lock at the boot also.
Now, I messed up the OS of the phone and t the moment it 'only' boots to cyanogenmod 10.2.0, wifi and Bluetooth aren't working and IMEI reports all zeroes if without SIM, 'unknown' if SIM is inserted.
I know his is a big trouble since I haven't freegee backup anymore but I'd like for the moment to return to stock firmware. Onestep at a time.
So, I need help in how to install stock firmware since the various methods I've tryed so far aren't working.
I got the right E97510H_00.kdz file downloaded ith the Original LG firmware program but I am unable to flash it anymore using KDZ_FW_UPD.exe: I start with phone in upload mode but the program reboots the phone, fastboot menu comes up and firmware update cannot continue anymore and exits with an error.
What should I do to let KDZ_FW_UPD continue with updating firmware?
SOLVED!
Just made a 910k type cable, connected phone to PC and set lg updater to Emergency mode.
Stock firmware restored perfectly and IMEI is working again too.
also...
when the phone reboots to fastboot while trying to flash kdz, power off phone, dont close/exit kdz updater, disconnect usb cable, switch to download mode again and the flashing should finish. i always had success with this one. hth!

Lg G4 H815 hard-bricked with different qualcomm soft?

Hello, (complete n00b here)
Several days ago I've tried to flash a 6.0 MM (from 5.1) to my LG G4 H815 phone. There was no option to do it automatically so I proceded to do it manually via flashboot.
I hard-bricked it to oblivion as in black screen, no response whatsoever.
While investigating @ the internet I've managed to understand I could get it fixed via quadcomm drivers (mode 9008).
Tried various "fixes" for H815 but was getting safari download errors. For some reason I tried a LS991 fix and it worked. When I started the phone it showed no logo but just a secure booting error 1006.
Still, could enter firmware download so I began to flash a lot of KDZ firmwares with no success.
LGUP shows my model : H81510H.
While in fastboot mode there is a note below (wasn't there the first time) with codes : 633 B46 or something like that.
While flashing anything it ALWAYS STOPS at 9% with a tot anti-rollback error. While flashing the code changes briefly where one can read smth like : LGLS991ZVA ver. 6.0
Managed to download some KDZ for that exact model, SAME ERROR. Tried to find / flash LS991ZVA with no success in finding a TOT file.
Also, managed to get ADB drivers up and it shows unauthorized in listing (LS991). Fastboot does not detect my device even in fastboot mode @ phone.
Please HELP!

H81510h is os version it is still at 5.1 I think....what may help is plug your phone in with lgup and drop the battery out of it then closes of LG up put battery back in and start LG up and find kdz that matchs your phone and make sure that it doesn't have anti rollback.....

Hello and thx for reply. I tried to do what u've said. It did something (I was looking for a while back). When I plug the cable back in, my windows 7 immediately installs quadcomm hs-usb driver (9008) and my phone acts as if it was dead. LGUP cannot find it in that state. I've been trying to QFIL the "proper" soft but it continues to pop different errors (using different QFIL versions). Either saharafail or some sort of download fail.
LGUP still presents an error (if I decide to "fastboot" it) @ 9% 0x2000, TOT antirollback version is smaller than device version.
How can I make sure I've got the proper KDZ without ANTI-ROLLBACK?

Thx again. Uppercut shows H81510H as LGUP did. Is it possible that it's somehow write-protected?
It confuses me, since during the firmware update on my phone, I get this small box below the picture showing wierd codes : 633A Bxx and when I'm trying to flash my phone, the code gets longer with LS991ZVA v6.0 and more other. It then stops.
Funny thing is, when I got the phone I couldn't even connect to the LG bridge to update it at all. I've managed to do it bugging the MTP protocol but THAT on the other hand prevented me from copying stuff / FLASH my phone to MM 6.0. Had to factory reset it back then and all went back to "normal" = LG couldnt detect my device but I could copy photos or stuff from it.
NOW, when my phone is bricked, LGbridge DETECTS my phone (in fastboot), downloads the newest KDZ update BUT cannot install it (same thing as in LGUP). Hence my question : is it somehow write-protected?

Have you tried to eset it by pushing power and volume own then when you see bootsplash then release power button and hen quickly push the power button again....
But in your case push power and volume down within the count or 20 then release power then push power button again and see what happens and then try the same thing on volume up......
Thanks for the reply.
I did what u've said. Despite no logo I tried to release power button for a second just after the screen's brightness goes up (I also get a small vibration @ start). Everytime I get secure booting error 1006 after a few seconds.
On the other hand when I did that with volume UP button there was no error but there was nothing aswell until I release power button in which case I got the secure booting error. All of the above tries were done with no USB connection with anything.

Do try with usb s well it may do something r do nothing......
Can't tell atm since I gave it to professionals. I'll wait and see how it'll turn up. Thx for all the effort tho, was nice to tinker with a lil help
@Longbranch did you solve this problem ? I'm in the same state but my phone model is H810, everything else is the same as yours.
Nope, not really. I gave it back to the reseller and my money got returned luckily.
The professionals I refer to above did install a specific firmware for the ls991 type. Firmware ZVB I think. The only one appliable apparently. Anyways, as I suspected the ls991 type is for the US and therefore it didn't work in my country in EU. My sim card wouldnt work with it. Besides, without the sim card, the phone decided to freeze and die after several minutes every time I turn it on. Swapped for LG G5 and it's working flawlessly up until this day.
good for you, what i don't understand is that it's a h810 model but now identify as ls991 does that mean you can convert it just by a Qfil flash? I may try another model flash if can't find a suitable Rom for it

Yes! That's what I and neutrondev telling everyone :
do not use qfil without the knowledge about the result!
The only working firehose file available out there is for the ls991 and that means if you use it it will turn your device into a ls991 without any way to get back to your previous device model!!

@steadfasterX since I have done it already is there any way to get it working even as an LS991 ?
here is what i did till now
the reason for using Qfill is that it went dead after flashing an H810 rom .
after that when it's in download mode it doesn't allow me to flash the ls911ZV5 ls911ZV6 ls911ZV6_12 roms that i found ( it says LS991ZVA )
so i went in fastboot and flashed boot/aboot/recovery....img extracted from the ls911ZV6 rom then it accepted the rom in download mode
but it is stuck in a hard bootloop ( reboots when it is getting in recovery but still has download mode yet no fastboot as before)
any thoughts ?

Yes it's possible. You can boot a h811 H815 or any other rom you like. Even LOS!!
Great right? BUT you are bounded to the ls991 modem and so you need to be in a sprint network to use telephony. That means the phone is now useless outside the US .
And you wrote you tried ls911 ROMs? I hope you meant ls991
I work on a fully working experience on every network though. Checkout my proof of concept for unlocking the bootloader thread
I can go into details on IRC if you like.

@steadfasterX thank you for keeping up with me ! ( btw what room on IRC ?)
for now I have used Qfill again and got fastboot working again and flashed TWRP ( not sure where ! ) so when the phone is off and i plug the usb it boots to twrp ( but it doesn't in recovery )
normal boot will show "secure boot error 1002"
then i flashed twrp img to recovery partition using twrp but it didn't work in recovery ( still reboots after showing Recovery Mode loading screen )
also tried to load some roms on the device to try them but I got error "file too large for filesystem " when copying them .
atm I don't know the state I'm in and what should be next ?
btw here are the recovery log and dmesg

Np we can bring you back to life but as already said without cell service. That's the price for the firehose and unlocked feeling you have now.
Did you found and read my thread here?
https://forum.xda-developers.com/g4/general/bl-unlock-unlock-bootloader-proof-t3648288
There you will find some more info and also the IRC details how you can find me. I'm online from Monday to Friday mainly.
It's much easier to talk in chat then here. once all the details are known I will provide a full guide.

Mix 2 bricked?! Flashing went wrong. Need help please.

Hey guys,
so this my problem:
I got the Mix 2 with the Chinese ROM. With the XiaoMiTool by Francesco Tescari I updated to the Global ROM V9.1.2.0 because I didn't want to wait to unlock the bootloader. This worked but I only had the choice to set China as my region. Since this was a common problem with updating the ROM without unlocking the phone I unlocked it and waited for 3 days to unlock.
Today I installed TWRP and installed the ROM xiaomi.eu_multi_MIMix2_7.11.16_v9-7.1. After this I was stuck with the Mi bootup logo. In TWRP I deleted cache, system, data. This worked EXCEPT for system. I thought updating TWRP to the newest version would help solve this issue. But since I'm new to this I didn't update it within TWRP but just installed the newer version via the commandfastboot flash recovery twrp.img. The result is that I can not get in recovery mode anymore. The only option is fastboot mode or the regular Mi logo endless boot.
What I tried so far: EDL flash method via adb/MiFlash but both don't work. The XiaoMiTool won't work too. The Mi PC Suite won't recognise the phone. When I use the edl.cmd the phone will go black for 2-3s and then return to fastboot.
I guess the problem at this point is that usb debugging is not turned on since TWRP installed the EU ROM and I could never get in it to enable the debug mode.
I couldn't find a solution to solve the boot up problem and can't seem to install/flash a new ROM at this point.
So what can I do? Do I need that special usb cable? Will the EDL points help me?
Maybe/Hopefully you can help me out.
EDIT:
When I turn on the phone it will directly go into fastboot mode. A normal start is not possible anymore?!...
EDIT 2:
I am now running the latest Global Rom this guide did it for me: en.miui. com/thread-1351514-1-1. html
Good to hear you got it up and running.

Unbricked my phone but now I'm stuck with the chinese firmware [BND-L21]

Hello,
I received my phone two weeks ago (BND-L21 version) and Friday I tried to manually update it to Oreo (with this topic : https://forum.xda-developers.com/honor-7x/how-to/manual-update-to-oreo-beta-emui-8-bnd-t3767044). I don't know what I did wrong but it didn't work (my phone didn't reboot on the stock recovery, only on TWRP). After a few try, my phone wasn't booting anymore, it was stuck on the orange message about the unlocked bootlader and the message "Your device is booting...".
I managed to get it back working with this topic : https://forum.xda-developers.com/honor-7x/development/firmware-updates-link-flash-risk-t3723810. The problem now is that I'm stuck with the chinese firmware (i don't have the Honor animation when my system is booting, I now have an Android logo on a black background). I don't have any Gapps installed and I can't flash anything with TWRP. When I try to flash SuperSU, i have an error extracting ramdisk failure and something with the boot.img.
Now the model of my phone is a generic_a15 and I don't know how to get back on track.
I'm a little bit desperate now, I don't know how to install another firmware. I tried to install this custom rom : https://forum.xda-developers.com/honor-7x/development/openkirin-aosp-8-0-honor-7x-t3746257 but I was stuck on the orange message again.
If anybody knows how to solve my problems, I'll be grateful
Thanks !
[UPDATE] I don't know if someone is reading but now my phone doesn't boot anymore and FRP is locked ?
Call Huawei customer support and get a ticket started to send your phone to the nearest repair center. Best of luck!

Last Hope to bring back my Honor 8 Pro to Life!

Hello All,
I have Honor 8 Pro from 1 year now and i have been using Custom ROMs (Thanks to the Developers here) from very long. I was using OpenKirin ROM and then when Android P was release I used FFW to get the latest one and tried to upgrade the phone (thinking that i know everything ).
And the result was catastrophic! Now my phone only boots to recovery mode and if i try to do recovery, it fails.
Current status (Attached Screenshots for reference):
Bootloader locked : says "PHONE locked"
Tried HCU: cannot see any phone info other than Serial number
I have DC-Phoenix+HCU 3 days pack. So please let me know if something can be done to revive my phone. Please let me know if someone can help.
Hi, did you recover your phone finally.? Actually mine also stuck with same problem but the only difference is my phone status shows phone BOOTLOADER Unlock, FRP - UNLOCK.
Unable to do anything but am able to flash twrp and have Access in twrp but unable to flash anything coz all partitions are deleted. Shall I keep any hopes.??
This is old but it might help.
