You could use KDZ updater and flash a stock ROM. Could you explain the problem more in detail please?

i think the best way is to flash a 2.1 rom thru fastboot im sure there is fastboot stock rom somewhere after that use mur4ik's custom bootloader builder to erase fastboot and recovery.

thanks!!!
but i was told from someone that if you
do it that way the phone wont turn on
in some cases!

I recommend you that you must be sure that this downgrade would be effect, beecause when you flash your device, the memory is modificated and its too hard to unmake this canges....
If you do it, can you tell us if the downgrade its result (you recovered your warranty)?

Can't i just flash 2.3.5 again after my warranty??

I'm sorry but you keep bringing this up and I have answered it numerous times. I told you here how to do it before.
Here it is again.
BTW: I HAVE NOT TESTED THIS MYSELF.
First of all, you need to get SwiftBootloaderBuilder from here.
(You also need .NET 3.5 SP1 installed, if you have Windows 7, afaik it is pre-installed with Windows)
Also download the correct non-fastboot KDZ for your country/provider & KDZ Updater.
Put your phone in fastboot and use the following commands:
Code:
fastboot -w (this wipes data & cache partitions.)
fastboot erase boot
fastboot erase system
fastboot erase recovery
Then open SwiftBootloaderBuilder and choose 'remove fastboot & recovery' Press OK to any warnings, then your phone may restart. (If it doesn't, then just press 'Reboot device')
Your phone will hang at the LG screen, in this case, pull the battery and USB cable out. Get ready by leaving the battery out, and then hold Volume Down and plug the USB cable in, while still holding volume down to put the phone in Download Mode. Fire up KDZ and choose the .kdz file you downloaded earlier Ensure that the type is 3GQCT and the PhoneMode is set to DIAG. Then start the flash. Make sure not to use the computer during flashing as it could cause KDZ to stop working and render your phone useless (bricked.)
It should reboot into Android 2.1, with fastboot & recovery removed and your warranty intact.
Hope it helps.

could i flash 2.1 stock via recovery
and then remove fastboot and recovery
by Swiftbootloader???

I think is possible

u use recovery to downgrade, search in the 4rum

Would it work if I flash by recovery then just unroot to remove fastboot and recovery???

When unrooting, you don't remove fastboot and recovery. To remove fastboot and recovery, use the guide I posted above.

[Q] trying to go back to original rom, but can't find any working method.

I'm looking for a way to get my phone back to a stock state, I don't care if it's unrooted in the process, I just want a fresh OTA capable stock rom. I have a couple PD15 images, and they flash in the boot loader, however, after trying to boot, it just stays stuck at the mytouch startup screen.
I'm looking at the tutorials found here, but none seem to be working. What exactly do I need to do?

Well do u still have a custom recovery or s-off
I have the completly stock rooted ROM 2.3.4 no ota after that
Sent from my T-Mobile myTouch 4G using xda premium

I'm using the PD15 images from here: https://www.4shared.com/folder/xDsyJF52/_online.html
I used the HTCDev unlock method. I have S-On
My issue is, is i want the official HTC kernel that comes with the latest stock rom. I cant find it to flash anywhere. So I'm trying to just go back to the regular rom, probably selling this phone soon anyway.

You can sell it for more with soff and rooted anyways the ROM I have has the stock kernel its completely stock just rooted

are yuo trying to flash a gingerbread stock or a froyo stock rom? which PD15IMG.zip files are you using? did you download the stock rom yourself and then rename it to PD15IMG.zip? are you sure your using the correct radio version .img as well? if all that is correct and youre still having trouble then you could try flashing the stock rom via fastboot mode
rename the rom to StockRom.zip (spelled exactly) then connect your phone in fastboot mode, then in the terminal enter fastboot oem rebootRUU it should then reboot into a black screen with a silver htc logo on it
make sure your StockRom.zip is in the same directory as your fastboot executable and run fastboot flash zip StockRom.zip
if it doesnt finish flashing or tells you to repeat the flash just re enter the command and it will work. then fastboot reboot.

I was doing all of the above, except checking the radio version and the fastboot oem rebootRUU! That could be it, thanks for that. I'll check it out and report back when I get some time.

I'm interested in your kernel that you are using actually, shoot me a PM or something if you feel like providing me links to download

So i tried the rebootRUU method, and still nothing (it says it works fine but will just hang at the white mytouch screen). I'm on HBOOT 0.89.0007 and RADIO 26.13.04.19_M
I'm trying to flash both the 2.3.4 before and the latest updated 2.3.4 stock rom.
Wish i could figure this out! Any ideas?

try to flash the stock froyo rom first.
http://d-h.st/ytv59wps2wzc heres a link to the PD15IMG.zip make sure the spelling is exactly like that all upper case except for the file extention .zip. and make sure its on the root of your sd card when you reboot into bootloader. the file shoild be about 312megs in size.

Tried, still stuck at the splash screen. I used HTCDev unlock originally with this phone, does that mean I also have to manually flash the boot.img from these zip's as well?
I'm obviously missing some step.

Please Help
I have the same issue. Flashtool thinks my phone is a D801. It boots normally for a few seconds and keep rebooting. Im Reading, dowloading and trying every method around since yesterday afternoon with no luck. I did replace the .dll you provided but i have a different error now, something like mismatch different files and it shows both files names. I just got this phone from a friend. it shows d801 tmo versión in flashtool so i think he was messing around with any tmo based rom (if exits). So flashtool does not let me flash the phone because of this(Think this is a 801 tmo)
I also tried lg suppor tool but it never download the firmware. It get stuck on downloading firmware or checking phone settings (something like that), I found my cell model on the back on the phone so im pretty sure is a SL980. So what comboof files i can use? Do i still can use the.dll provided? Do i have to rename something?(btw...i did and didnt work).
Any other tip? Did i miss something? I have no phone now so im kinda desperate. Thanks in advance for any help.
Sorry for any mistake, english is not my first language.

I will try ti explain you later what i did to fix this issue

ok this is what i did to unbrick my phone in your same conditions, in some steps maybe i made some mistakes but i went to the fastboot mode and there i replaced all kernel files of ls980 to fix the issue:
first you have to proceed to back to stock your phone with the T-Mobile USA D80110C_1.kdz :
http://forum.xda-developers.com/showthread.php?t=2432476
now your phone is a full d801, it will boot the system but will be unstable, you must be fast to go to make the developer options and debug your phone, make it on plane and and charging mode, maybe you will be able to do it after some reboots, u must insist.
download the ioroot11 program to root your device, remember always that is unstable, your device will be recognized for not long time, so you have to open the ioroot program often until it recognize your device and root it with the program.
after this step, if your phone is rooted but is still too much ustable to use the adb command (i tried to sideload and push the recovery but it always made me a sideload error), download this program:
http://forum.xda-developers.com/showthread.php?t=2633941
is a simple tool to flash the recovery, it worked in my case, you have to install the recovery of the d801, in my case the philz recovery worked, if everything will be right, you will flash the recovery.
When i was inside the recovery i tried to flash the justin sprint t mobile through the sideload command but it didn't work, same with cm11, i flashed the ls980twrp.zip and when i tried to go to recovery again i was in fastboot.
from fastboot i used the command fastboot erase to erase the partitions: aboot, boot, dbi,laf,misc, persist, recovery, rpm, sbl1, tz.
to erase you must use the command fastboot erase aboot aboot for example, to erase the boot you must repeat boot(fastboot erase boot boot) and so on.
after erased all files i flashed the partitions of ls980:
http://downloads.codefi.re/autoprime/LG/LG_G2/LS980/Stock_Firmware/zv7_partitions
cmd fastboot flash aboot aboot and so on, (i didn't flashed the primaryGPT).
when i flashed all these files i pushed power volume+ and i was in upgrade firmware, so i went back to stock with zv7tot and dll..
it wasn't simple to find a way to back to stock, i guess to made some mistakes but i fixed my issue in this way, i am responsible of what i do with my phone, i cannot guarantee the same results with the others

if you can go to twrp you can flash with adb, i wasn't able to go in recovery, just download with the d801 firmware, that explains why it was complicated

Thanks for all your help. I was able to erase everything via fastboot and my phone fell down and power off before flashing img and now is dead. I have a big blue pitbull inside the house who makes the disaster.,.lol. i just got one white from a friend for $160. Im sure this thread can help any people with a brick device. Thanks again.

I had got to the point where I am running the d800 version on my ls980 and it is unstable as you said. I believed I had found a way out but when I connect to the computer no matter what I do I get no adb for no reason as far as I can tell.
makes no sense at all to me as I had adb before all this perfectly fine.

you gotta go do device drivers and your device will show up as some unknown device so you install the adb devices for your phone and then you should get adb to show.

Yes...
But normally any rom u flash, u will still have to go in settings an enable it.
The only way u can flash rom is via the recovery tool. The recovery tool also installs twrp recovery. Since ur bootloader is locked it probably brick the recovery.
If u get a rom to boot successfully proceed in unlocking the bootloader.

But buddy his bootloader is unlocked where as mine is locked :crying:

Did you wipe data partition? No one told you that before, so I'm curious. Do it from recovery (you didn't tell your recovery is dead, so...).
Had this issue, when I forgot to wipe data after switching roms.

If recovery does the same, this is a hardware issue.
I guess you are from India, so take your device to a service center. In case your warranty has expired, go for the 3T, replacing the mainboard does not worth the money.

P9 Lite Bricked. Help me!!!

Hello,
I was always a Samsung fanboy, but than I decided to buy the P9 lite (VNS-L21 single sim)
I wanted to flash the android 7 update for my phone, but I was such a noob in Huawei, that I didn't understand a word. But i tried to do what the instructions said. Now my phone is bricked. I can go to recovery, erecovery (which can't download anyithing) and download mode. I heard of this fastboot stuff as well, but I don't know how to do this. I tried to flash as many roms as I could with dload and it didn't work, after 5%, it said it failed... Now I don't know what to do. I think somebody (expert) should make a clear tutorial for noobs. Oh and I almost forgot that i don't have root, custom recovery, and things like that. I just bought the phone, I didn't want to make big changes, just new android. Is it possible that after this Huawei would fix my phone, if I couldn't? Or warranty is void? And sadly I don't know more of my phone because I'm not ina rom, and the phone and papers don't say more.
If you could help me, I would appreciate it:

Turn off your phone, connect to the pc while holding the volume down button, you will end up in fastboot mode.
I assume you have ADB and drivers installed (if not, install ADB and device drivers).
Optional: unlock your bootloader if it's locked.
Download the latest offical rom zip for your phone version (the marshmallow one), extract the update.app.
Use Huawei extractor to ectract the following files (google is your friend in this one, but its not difficult):
boot.img
recovery.img
cust.img
system.img
After you've done this, connect your phone to the PC in fastboot mode .
Open a command promt from the folder where the extracted files are (shift+right click, Open Command window here), enter the following commands
fastboot devices (you will see the list of attached devices with a lot of random number + fastboot)
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img
fastboot reboot
After all this, you should be good to go, just be sure you are using the correct rom for you version.
Or you can just serach on the forum and find this.

Post here IMEI and SN from the box of phone and i can try get your bootloader unlock code...

If I would unlock it, would fastboot work? Because fastboot pc app recognizes my phone, but my phone says in fastboot mode, that I should connect itself to pc and open hisuite. WTF?

Until you have bootloader unlock you can not run any fastboot flash command...

What is the error? - Have u disconnected the device from the PC during the update?
If not, try to update again and just disconnect the device from any USB connection...

Hello. I disconnected it from everything (for example USB)When I tried to install it said something like incompatibility version, but it couldn't be because I tried many roms for my phone. And I tried some dual sim roms as well because, I thought that it might work... But then I will do that unlock if it will do good. Thanks for the help Without bootloader I can't flash from dload as well?

Heyho,
the dload method works always without unlock bootloader. But, u can't flash for example an B161 over an B3xx (what nougat is) if the update u installed modified already the oeminfo u are not able to flash any rom below B3xx (nougat) via dload.
-
In that case u might use the official rollback package (never tested it myself) or, u unlock ur bootloader, flash a TWRP recovery matching to ur current FW. Flash from there a oeminfo + custom.bin (lower than B3xx) and flash the FW matching to the new oeminfo via dload and stock recovery.
Regards,
Sebastian

If you have custom recovery, wipe everything. Data, system, boot. extract update app (which is your stock rom) with huawei update extractor. go to custom recovery, flash stock boot IMG and stock recovery IMG. Power off, use three button dload method, reboot, when booting press vol up for three second, now you are in e-recovery. Press shutdown. Press and hold power and vol up for stock recovery. Do factory reset. If need do the factory reset 2/3 times. Now you are with locked bootloader.
