Help needed - Huawei Ascend P7

Fellows,
Please help me in my problem,
I was on b817 recently then I decided to change it as it has many bugs,
Finally I get to b800(transition from),since then I'm stuck on it, I can't downgrade or upgrade always I get " there is no update.app " message though the from is in my Dr load folder. I tried to update/downgrade. Through update apk and 3 buttons method but all failed.
I'm running everything stock I never tried to modify anything and I'm not rooted. I sent Pm to some senior members here but no one has replied me. I'm a noobie member if anyone would help please on how to get this problem sorted step by step with links to required programs please.?
My customs is 433 ??

Hello, is the file located on /dload at your SD card? Did you extract the update.zip first? If yes/ not try it with(/out). If that all fails you could extract the update.zip and flash all images manually through fastboot.

Yes it is In sd card root.. but to go for b621 or b805 we have to put the update.zip file in dload without extraction..
I said I'm noobie Here I don't know what is fastboot and how to flash anything through it ???

I happened just like you B 817.After the downgrade puts B621 UPDATE.APP on dload folder in the phone memory or SD card, turn off your phone, press simultaneously + and - volume and power button and the phone will write a alone software B621.I hope I helped you.Before that make one factoey reset plz.

I assume post #6 here (http://forum.xda-developers.com/showthread.php?t=3211971) already answers your question. If that doesn't work like it should, I could describe more detailed what I thought of, sorry.

How to flash through boot loader?
What application do I need to flash it?
Sorry for that but I'm noobie..??

First you need to set up your PC correctly. I assume you are running Windows.
So, download and install the HiSuite to get all needed drivers. Then follow this (http://dottech.org/21534/how-to-ins...ows-computer-for-use-with-your-android-phone/) instruction, I recommend to use methode 2.
Now shut down your device, press volume- and power at the same time. You should boot into the boot loader (white background). Maybe the device has to be connected to the PC for that.
Now you could follow the instruction in the link in the last post of me. Since you booted manually into the bootloader, begin with the fastboot command. (All files that are going to be flashed have to be in the location you put the fastboot-files (as described in the link) in.
I hope this is understandable. If not, feel free to ask!

Well, many thanks for your help,
I've downloaded all applications required on computer.
I'm planning to roll back to b621(already I have the zip for it).
Then what to do exactly Or what to write in fastboot menu ? (sorry I'm complete noob. ???

I think (but I'm quite not sure) that B621is instead of beeing a full firmware just an update. So I'd recommend to use B609 as full (!)version. Maybe you find the B609 stock recovery somewhere to download or you have to extract it with the huawei-update-extractor (just google and install it).
Download also the newest versions myrom and twrp, save the twrp file and the B609 stock recovery in the directory of your adb folder, the myrom on your sd card.
Now you boot your device into the bootloader. How to do this is described in my last post. In big letters the status of the bootloader is showed up. If its locked read the xda thread about how to unlock and continure afterwards.
Type into cmd (how to open is described in the adb tutorial): fastboot flash recovery [name of recovery.img] for example 'fastboot flash recovery recovery_twrp.img'.
After that unplug the device and shut down trough pressing power for some seconds.
Press volume+ and power at the same time and you will boot into the custom recovery. Here you're gonna flash the myrom.img.
When that is done you should flash the stock recovery with the same procedure like you did with twrp.
Now you could flash the B609 with the dload method.
I'm sorry if this all is a bit messy, I'm just writing on my phone and I'm a bit tired..

Victory.....
Many thanks for your help I'm on b621 now.

Nice, your welcome?

*FIXED* No OS installed no backup, install stock rom with TWRP *FIXED*

**UPDATE RESOLVED**
For anyone who searches and has same problems.
I needed an sdcard to get the files onto the phone.
To recap - it was stuck in boot, TWRP would load and stated no OS installed.
1. In rooting guide as per Here download file linked in the guide and unzip.
2. From folder 3 of that zip file there is a folder called data containing stock.img - place this onto sdcard.
3. Then go to this thread and download the files as hosted on mega.nz - over 2 gig.
4. Extract that zip to the sd card so that on the card is a folder called 'dload'
5. To confirm, the dload folder should have update.app and 2 folders called dt and hw
6. Put sdcard into phone.
7 .Boot into TWRP
8. Goto install, select storage, select your sdcard then select stock.img, agree to install, ignore message about no os.
9.Once that has installed my phone just restarted, EMUI came up, read the dload folder automatically and ran.
Then once phone started it found a newer update and installed that.
Phone is now working, unrooted and bootloader is locked again.
All this was found on the XDA site, just across various posts.
Thanks again to all.

Hi all.
Please help, I'm a ****!
I unlocked bootloader with Huawi code from thier website.
Then I installed TWRP
Which in turn installed SuperSU
All rooted, jobs a fish. as per - This one and This thread.
Decided I dont need root anymore.
Tried to reset and wipe the phone.
Went into TWRP did a factory reset wipe.
Then went into TWRP again and did advanced wipe, and selected everything.
(yes yes i know, what a tit)
So after that i get the 'this phones is unsecured' message, press up vol 3 seconds, press power button to conti, wait 5 seconds etc.
so I wait, and it sticks on 'Your device is booting'
Restart, can get into stock recovery and hisuit will see the phone and try to restore it but fails and say my device is not supported??
Can get into erecovery and connected to wifi to try and update but does not find anything to download.
can get into twrp.
I have downloaded a stock rom as per -- This ROM
Perhaps this is not the correct ROM, but then how do i find out the correct ROM needed now I can not access phone details?
Forced that onto SD card but TWRP will not run it and says it is corrupt.
I can see it with ADB and device manager so my question really is....HELP??
How can i get just stock rom back onto it and then un-root and re-lock the bootloader?
Cheers in advanced.

you can find the model (for me it's vns-l31) on the back of the phone, just find the corresponding oeminfo file and the update file. flash the oeminfo file, put the update file from the rom zip in the dload folder and reboot using the 3 button combo till it says something about installing update
here's a list of update files: https://forum.xda-developers.com/hu...huawei-p9-lite-firmware-compilations-t3517124
and here you can find the oeminfo files, there's a google drive link under oemfiles, at least for the vns-l21, 22 and 31: https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873

Hi, thanks for the reply.
All of those links refer to the P9 Lite - is this the same internals and software as the normal P9?
On the back of my phone it has - Model- EVA - L09 FCC ID: QISEVA-LO9 - IC: 6369A-EVALO9
I do not see how this relates to specific oeminfo file?
Lasatly, can you provide details on how to flash the oeminfo file to device and do you mean the following for the update:
So in rom sip there is a update.app file - extract this to sdcard in a new folder called dload? then install that via twrp?
Cheers

first of all, no, p9 is a different phone, but you posted on the p9 lite forum. i'd suggest posting this question on the p9 forum.
i don't know exactly how it works for the p9, but it shouldn't be much different.
for the rom zip: inside that zip there's an update.app file, that file should indeed be put in a new folder called dload, but it won't be installed through twrp.
on the p9 lite it works like this: you flash the oemfile through twrp, and after that push and hold both volume buttons and the powerbutton till the phone reboots and shows an update progress screen, then you can release the buttons. now the update file will be installed. but then again, i don't know the procedure for the p9 so be sure to post your question on the correct forum.
edit: i've taken a look on that link to the stock rom you tried installing, it's a zip file that contains the dload folder, just put that folder on the root of your sdcard. do make sure it's the correct version.
you will have to flash the stock recovery for your phone however, and if the p9 works the same way as the p9 lite you should find an oeminfo file and flash that with twrp.
So sorry, I didn't realise I was in the lite forum!
I'll ask a mod to move, sorry and thanks for you help.

here's a link to the oeminfo for eva -l9: https://forum.xda-developers.com/p9/development/c432-oeminfo-flash-twrp-t3384903 i think that one should be flashed in twrp, and after that you can use the 3 button combo
no problem at all

PRA-LX1 I want to install stock firmware.

I want to flash my phone with stock firmware, but I cannot find it anywhere.
I am looking for PRA-LX1C738B123.
I own Huawei p8 lite 2017
I wiped my system because I wanted to install other rom, it didn't work so I want to go back to the original.
Unfortunately I wasn't smart enough to do a backup before so I am stuck atm. The bootloader is unlocked and flashing works, I can boot into huawei eRecovery and TWRP. (eRecovery gives the getting package info failed error) I have tried the dload method with other app files, it fails at 5% every time tho.
I tried using Huawei Update Extractor and Firmware Finder but I cannot find the exact firmware.
Could someone help me with installing my firmware? Oh and I am kinda new and it would be nice to get some guides,
Thanks.
I have the same problem but with a different firmware.. now only thing i can do is use dc-phoenix paid software (15$ for 72h of use). I will try that tomorrow as i also can't find exact same firmware it was on my phone.

Thanks for reply. I will take that into consideration, but from what I see you were looking for PRA-LX1C432B106 and they indeed have the c432 roms there, however they don't seem to have the ones that I have been looking for. They have a list of firmwares online. Anyway good luck.

Hello ! I think I could be of some help since I encountered the exact same problem !
edit: well I just realized I can't find your ROM with firmware finder either, sorry for the failed attempt
In your case I'd try with each firmware until one would work or a I tried them all.
You need some utilities first :
- Firmware Finder
https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146
It will allow you to find the stock ROM that fits your model
-Huawei UPDATE extractor
https://forum.xda-developers.com/showthread.php?t=2433454
It will allow you to extract the .img files from the firmware previously downloaded.
-fastboot and adb
https://forum.xda-developers.com/showthread.php?t=2317790
The programs that will allow you to flash the .img files.
Now:
1. Find your ROM using firmware finder (the model is usually on the box you received the android in).
2.Extract the necessary .img files : system.img, boot.img, recovery.img.
3.Reboot into the bootloader, connect your device to your computer, open a cmd exe (powershell in my case) by holding shift+right click on the folder containing the .img files and flash each .img file, e.g. for the system file:
"fastboot flash system system.img"
4.then use "fastboot reboot" and after that shutdown your device
(in my case even after flashing the .img files I was greeted by a blank screen, so I shutdown my device holding the power button).
5. Boot into recovery holding vol up + power buttons (be sure to disconnect your device before shutting down and powering it up again) and choose factory reset.
It should then reboot into ROM installation procedure where you will have to follow the same steps as when you booted your device for the first time.
edit: formatting
Also, as far as my limited knowledge goes, there is no custom ROM officially supported for our dear device.

Yes I had the exact same problem, but once I did what I described, by rebooting into recovery (without twrp), I finally had the option to restore factory settings.
I believe the issue is in the fact you don't have access to the stock ROM for your model.

But keep updating in case someone more knowledgeable peeks in.
similar problem....I was fairly good but play store was stuck in pending download....
I did a wipe in TWRP, and ended with a black screen...
I can boot to eRecovery, but it fails.and also to TWRP.
when attached to PC it keeps being seen and unseen as if its stuck in a power on cycle
Any help would be greatly appreciated.

Here is the solution for every PRA-LX1: [http : // www . htcmania . com / showthread . php ? t=1326478] (sorry for the spaces, but I don't have enough posts written to post external links )
Unfortunately, it's from a spanish forum. I didn't found any problem to follow this tutorial, but maybe for someone it could be a little difficult.
Anyway, it works!

Where did you find the C432 firmware? I can't succees to find it
Flashing to a completely empty phone via DC phoenix or manual via fastboot still didnt got my device started. Sometimes I end up in the eRecovery and sometimes its just stuck at boot.
I tried different version from the hicloud but none so far did the trick. Maybe someone can point me into the right direction so i can finally rescue this phone?
EDIT:
PRA-LX1C432
Sorry cant link to these files since i don't got 10 posts. Maybe PM ?
Copied the Mega TWRP backup (B100) to SD card
Flashed TWRP via fastboot
Disconnected the USB cable
Boot into TWRP
Restored TWRP backup
Restarted phone into fastboot
OEM unlocked it
Got booted into TWRP since no stock recovery there
Booted into fastboot again
flashed stock recovery
Android started to work!
Tried to update to B164 and failed
Reboot
Now it offered B110 and I tried to update to B110. Success.

Also i noticed everytime a OTA fails you get the full version offered on next boot. So you should get a full B164 aswell after it failed

[TIPS] Revert Custom Rom to Official and untouched - Hard restore

Hi!
I see the large number of requests concerning the roolback of a custom rom to a official and untouched EMUI 4, i decide to create this thread.
After follow that methode, you able to rest on official EMUI and get the new update automatically on OTA (directly on your phone) OR try to install custom rom with a clear and good base version.
1. You ave access on TWRP?

P9 lite brick precision:
In my personal experience the "p9 lite" is very easy to flash, mod or other tips and the risk of HARD brick is very very tiny.
If you see this page and your phone bootloop, relax, keep calm at 99,999% you have a little and ridiculous brick
Good luck and flash happy!

I can do everything up to point 6... won't enter to twrp... stays on Your device is now booting...
Update: I can now reach point 7 but now won't do dload (3 buttons) method... Huawei logo all the time. Can't even turn off the phone
In my other thread you post the same problem but is not entirely the same..
You succeeded to enter on fastboot mode? Flash recovery?
If you follow the steps 1-5 is impossible to fail the 6 point..
You have acces on fastboot mode or not?..

I did update the post... 3 hours ago I wasn't able to enter TWRP, some way I did managed, now I can enter fastboot, I did flash custOEM (sorry I don't remember exactly the name but it's the one of your post) .zip file. Now I can't do dload method, stuck on huawei logo. If I try to go to recovery, I got red message "phone fail validation"...
I know, I post on both but I was trying to do everything...
just tried... validation red error message won't let me go to TWRP now...
You have a VNS-L31C432?
Your phone does not enter at dload mode?
Wipe all partitions an retry flash a oeminfo for your model phone (if not C432 you need right oeminfo).

How can I wipe all partitions if stuck in Huawei logo? Is there a way to do everything from adb command line? (I'm using Mac and cannot use all the tools I've found here XDA neither hiSuite which is basically a backup photo/video only the Mac version).
Thank for helping, really appreciate
To answer your question in the other thread, yes bootloader is unlocked and I am on C432.
What's your rom have before the bootloop?
You have the right version of TWRP for your rom?
If you have a MM version Don't flash a TWRP for N.
Send me a link to TWRP version used (thread forum)

Before the bootloop I was on L31C900 (on the phone) but I did actually flashed C432B160 because I did rollback. TWRP used I've found in the other post where there's a OEMfile to flash (but for this I need to double check because I did look so many pages which I am not 100% sure.
I not have experience on other model that C435.
But i suggest to find a oeminfo for your variant (C900?)
For TWRP you need flash a version for MarshMallow HERE
Flash it and pas return here (fastboot flash return and first enter to new recovery)
Hi, found Windows emulator for MacOs so I extract from update.app boot.img and flash.
I did format all partitions as told using a proper twrp this time.
What's next step, system says NO OS INSTALLED?

Flash partitions on .img files is not needed.
Just find a corect oeminfo for your model phone.
Flash it on TWRP recovery.
Use dload methode to update on basical version (MarshMallow b160).
After that, unlock bootloader again and make a factory reset.
Switch on your phone (the first boot make long time).
Update on last emui on OTA.
Done!
After that you able to install a custom rom.

Thanks again you're saving my life!
IT won't turn off so been always on it won't keep the charge... Writing so because apparently it won't go to download mode (dload) if plugged in. On the other way if I unplugged from power it won't even start. Shall I force to download mode using console ADB or FASTBOOT? I had looked but can't find anything...

Correct. Because I'm not able to switch it off it won't keep the charge. When discharged, the minute I do plug on charge it wakes up... That's the loop...
My main question is: does a command exist to enter download mode using terminal?

You have a hardware bug?
No abd command to enter dload mode..
Try flash a update.zip with twrp (not guaranted)
After that unlock bootloader again and make factory reset.

Hi, I followed this guide to go back to stock from elite rom. I flashed my oeminfo.img on twrp and then went to dload combination. Do I have to unlock the bootloader after the reboot? Thanks!
Hi,
I followed your guide and it works perfectly thanks!

bricked device with oreo, old unbrick doesnt work

hi guys,
yesterday i installed the oreo beta on my VTR-L29 but then i brickedd it *cry*. unfortunateley the unbrick methods found here in the forum don't work because the oreo update made some changes in the system file structure...
has anyone an idea what to do?
maybe someone can provide me a recovery image for twrp? (one for oreo, otherwise it wont work) so i can give this a try...
after over 10 hours of fiddeling around a found a really easy solution:
most of you know HWOTA helps with this, but the "normal" version wont work after flashing oreo. but this version is flashed via twrp and is still working!
but you will need a oreo compatible twrp, which you can find here
i know the links are to mate 9 software, but since the p10 and mate 9 are nearly identical, it works on the p10 as well
can you post the step by step guide?
i am on oreo 8.0.0.046 and want to flash another version, or downgrade to nougat because few things don't work on this version
i dont know if downgrading works, i just reflashed the latest oreo.
accordingly to the first link it should work, just flash the TWRP from the second link and then follow the instructions from the first link.

i did sucsses to install twrp but on the second step, when i press on install on twrp, the phone restart to erocovey and failed to find the files. what am i doing wrong?
i think that i am stuck with that version forever....
if you reboot to erecovery, you have not successfully installed twrp. you have to install it with "fastboot flash recovery_ramdisk <path to twrp>"

Bricked, no TWRP access, any ideas?
Hi.
I know this about a P10, I have a P10 Plus (VKY-L29C605), but the process should be similar, I think.
I bricked my phone after succesfully upgrading from B174 to B321 using HWOTA. After which I decided, since I was at it, to flash the Hyperplus Kernel. This led to a bootloop. To fix it I decided to just go ahead and HWOTA B321 all over again and get over it, and would have probably gone just fine, except I decided to rebrand (C605 > C432) while I was doing that, silly (no, stupid) mistake. This led to the brick I am currently expriencing, I have no recovery access, erecovery or TWRP.
So now I am left trying to unbrick the phone. I extracted the UPDATE.APP for both update_all_hw.zip and update.zip using the Huawei Extractor Tool with no difficulty, except unbricking methods ask for boot.img, which I could not find, so I went along without it and flashed: cust.img, recovery_ramdisk.img (using fastboot recovery_ramdisk command for Oreo), and system.img. All of the commands completed succesfully, but no shebang, still bricked and no recovery access. I figure this has to do with the rebrand as the result after executing the command "fastboot getvar vendorcountry" shows the rebrand pulled through (hw/eu 432).
I am currently downloading HWOTA8.zip (3GB worth of download) to see if I can do something it. I am also downloading the L29C432B360 OTA-FULL, since I believe I am not getting any progress becuase I used the updates for L29C605B321.
The kind people at funkyhuawei told me they could fix it with their tool, but I don't have the money for that right now.
I will post updates, but any ideas would be greatly appreciated.
Many of us have posted over this in the last couple of days. Seems like Funky Huawei unbrick tool was the mehtod to get it work for me. You could try that!
or use dc-phoenix for me it worked (= in the moment i try to capture the usb ports kommunikation so i have the tool with the aktual firmware longer for 3 days :silly:
would first give dc a try 20 bucks for 3 days is ok i think (=

Must download some software for your phone, unzip update.zip, decompile UPDATE.APP to .iso files, (like recovery.iso, system, iso, vendor iso, boot iso) use fastboot and 10 minuts job, I brik my device over 10 thimes, and repair it.
So I was able to get the C432B360 firmware and I flashed it, but no I can't enter recovery mode because the battery is low (red lightning bolt/red led flash). Anybody know how to charge or force recovery mode boot from fastboot?
If anyone needs, can use my DC-Phoenix account, I don`t need it anymore.

Switch the phone off, connect to PC - must have drivers and ADB installed.
Boot by Volume- & Power - must boot to Fastboot.
Flash boot.img - corresponding to your installed ROM, to the boot partition.
You can use Firmwsre Finder - from PC or another Android to download update.zip (FullOTA, corresponding to your ROM), unzip and extract boot.img from update.app by using Huawei Update Extractor on the PC.
And take care what you flash and where
