Cannot upgrade P7-L07 with EMUI 2.0

Hi,
a friend of mine has got in China a P7 with a strange EMUI 2.0 firmware (I always knew that P7 came with 2.3 since the first version). I wanted to upgrade it to the EMUI 3.0, then I downloaded the package from emui.com, I extracted the dload directory and copied to the internal memory (the same procedure I succesfully did with mine) but when I booted it holding Vol-, Vol + and Start button I just went into the stock recovery interface.
I though was a problem of the recovery, then I restarted with adb into bootloeader mode but the screen was all empty except for "fastboot mode" wrote at the bottom. When I tried to flash another recovery I got an error saying that flashing the recovery was not allowed.
Anyone knows what the problem is?
Thanks in advance

locked bootloader..

And also is resisting to any attempt to unlock: do not give Product ID so I cannot produce the unlocking code, neither are working all methods I found on the web. I may have to give up

maybe there is a firmware for your p7-L07 like there is for the p6-u06 where you can flash a so called unicom version and first downgrade and then upgrade/update..
and hopefully this downgrade unlocks the bootloader..
just my thoughts..

Thanks blueIBI, the problem is how to flash it, since the normal way do not work. After copying the dload directory on the phone memory, if I use the system menu to perform local upate or I reboot by pressing Vol+ Vol- Start I always end up in the recovery menu, the firmware gets never installed.
Will try harder.

Are you sure this is original P7 not some chinese crap looking like P7?

The phone belongs to a friend of mine. I own another P7 and they look exactly the same. It came in the original box with everything, so I have no doubt that it is original.
The fact that it has EMUI2.0 make me think that it was one of the first released to the market. The phone is working fine, just it is not upgrading on-line and I cannot find a way to upgrade it manually. I will try contacting Huawei support.

Sadly, you are not alone with this problem. My experience was similar to yours. I solved it by throwing the phone away and buying another. Unfortunately, my second P7 has faulty flash memory and is almost useless. I'm now awaiting the delivery of my third P7. I suggest you buy another and avoid EMUI 3.0. Good luck!

A question? How can you do factory reset through settings when you have a bricked phone? I find this very strange!
If by any chance you still can load the OS, get the quickboot app in the market. It will get you to fastboot and than maybe you can install recovery.
All in all, I still don't understand, is your device bricked (can't load OS, just constant reboots - loops), or you just can' downgrade to EMUI 2.3!
Good luck

Probably "brick" is not the exact word, but everything which i wrote in first post is true .. cant do a factory reset from settings and via 3 buttons and cant flash again emui 3 not only 2.3 and the phone just restarts or stuck on first huawei logo when i try to do that and cant charging when is turn off ..etc .. )) When i get quickboot from market what i have to do with it ? Thanks !

To install quickboot you need to load OS which you apparently cannot at the moment. Did you try this: http://forum.xda-developers.com/ascend-p7/help/stock-recovery-stuck-bootloop-t2875935

I totally bricked the phone ... i wrote in fastboot "fastboot flash boot boot.img" and after that the ph0ne begin to restart in timeless circle .. and still do it ... please help emergency ))

Try the method on the first post: http://forum.xda-developers.com/ascend-p7/general/reverting-emui-3-0-to-2-3-t2934277

I fix it ... turned out i was installed wrong boot.img .. may be of huawei p6 and the stock recovery which installed doesnt work .. now instaled working and everything is ok Thanks 4 wish to help me !

I have a similar/the same issue as some people above described.
I reverted from CWM recovery to stock recovery (same stock recovery img as I used before succesfully). Now the phone can only boot to stock recovery (Reboot system now, Wipe data, Wipe cache, are the only options.
The phone is not detected by adb on that screen, so I can't try to reboot to bootloader using ADB. I also can't get into bootloader from volume button + power, because the phone boots immediately to recovery after I turn it off.
Fortunately I managed to solve it, so for reference:
Remove SD card
Place full (no incremental update) update.APP file on external sd card in /dload folder (B609: https://mega.co.nz/#!akcBCZBJ!4jLhlNsH54H-3DHeK3xPkzT3fWIHBR6QtbOllubdz5Q) using a different device (computer)
insert SD card
turn the phone off from the recovery loop by holding all three buttons (VOL+POW) at the same time. It's a bit tricky, but keep trying until the phone is off
Insert the USB cable in your phone and connect it with your computer (haven't tested if it simply needs power, or an ADB enabled computer)
Then immediately press all three buttons again
You should enter recovery again now, but the phone will immediately start flashing the update.APP ROM.
You will lose all user data though!

same problem here
Hello to all,
I had the same problem that my phone doesn't go on and time after time boot fails,
i read this solution and it works great i am updating my phone.
only i take the power + vol down and when the logo came switch vol down to vol up.
thx for youre help and sorry for my bad english
grts rob

I cannot upgrade any further

Hello,
I tried for a few days to upgrade my huawei to build B586 but I haven't been succesful. I unlocked my boot and tryied to upgrade trough brick method(but switching the img files to the b586 ones with huawei extractor). I have no option to update from local and the vol+,- and power buttons do not work. I get stuck at boot screen.
My curent build is B574. Do you have any sugestions how I can upgrade? or downgrade than upgrade? The update to 6.0 was done via update from local option,which i don;t have anymore.
Thank you in advance.

It works with me in similar situation, not sure if it work with you!
Downgrade B574> B300
and then...
Upgrade B300> B586 or B588

Hmmm... I had a similar problem. Coming from the RRevolution Custom Rom, when i tried flashing stock again i couldn't. The Power+Vol.Buttons method would give me bootloop. Even though the phone was booting, i followed the unbricking guide, flashing boot,recovery,system and cust (search it up, it's in the forums). After flashing everything and rebooting my phone, it went straight into the upgrade method (the one you get with the Power+Vol) and installed B586 just fine. No problems since and i am now using the B588, so it might work just the same with that one too. Hope this helps

Did you tried put B300 on the dload folder and then press 3 buttons?

From what I understood, you can't use the 3 button method, right? The phone will just boot... Try pressing all three and when you see the boot logo just release the power button and keep holding the other two. I've seen people getting over such problems by doing this. It probably sounds stupid but i would give it a shot... Also, try putting the upgrade.app file both on internal and external sd!

eRecovery is achived by volume up+power buttons right? When I do that It enters in update and says update failed
EDIT: removed the dload folder and succesfully wiped my phone, I will try to upgrade now(fingercrossed)
EDIT 2: I succesfully upgraded to b586. When I pressed the 3 buttons I got stuck at the same boot screen. When I pressed only volume up+ power button it workd.
So if any1 will have the same issue he should defenetly try this out. Big thanks for everyone who responded in this threat :good:

Reverting to CRK1

I need some help getting back to CRK1. I updated to DRL7 using the Update.zip method, and now when i try to odin the crk1 files back it just fails after it says "Setup Connection".
I don't get an error Flash
I've wiped both in the phone and in recovery
I've tried downloading the CRK1 files from two different sources
Ive tried an "official" odin and a "modded Odin"
I've tried USB 2.0 port and USB 3.0 port
I've used CSC Home and NON Home
I don't know what the hell is blocking me, or if I'm doing it wrong. Am i just doomed to stay on this dead end beta forever? Biometrics stop working in the background and i have to restart my phone to get in to it without using my damn passwords (Apps too) and my banking app just doesn't work on it in General after the update. I even wiped it and reinstalled and I need my bank app.

If it's on windows 10 that's the problem. You need to use windows 7. I don't know why but that's what a lot of people are running into.

Try a different windows 10 then because it's working on some but not others.. I had to install windows 7 in a virtual machine on my Ubuntu server in order to flash back because it wouldn't work on Vista either..

Tried with my work PC and home PC, no success.

Finally got it to work w/success...................however, it's in a bootloop..........will reboot to the Sprint logo screen.......then show the small dialogue of android apps...........then reboots again................any advice to get out this?

If you're downgrading, you'll have to do a factory reset or you'll get a bootloop.

I just want to get out of the bootloop..............know where I can get the previous version of the stock rom that I can try via Odin? the one we got in November would be what I am looking for...................I can get into downloader mode so that's what I want to try

Did you try to get into Recovery mode and then delete cache and then do factory reset? Or are you saying that you are stuck on the download screen and can't turn the phone off?
I just did the Odin on mine to go from DRL7 back to CRK1. When using Odin (regular, not patched) I did it on my Win10 laptop. I ran Odin as an administrator and it worked perfectly first time. I did unselect the Auto Reboot option. I waited until Odin ran all the way through until it gave me the success and it said Pass. I unplugged the USB cord and manually restarted. It started off in a strange looking download screen and said error. I was able to get it to turn off and went into the recovery mode where I deleted cache and did the factory reset. This time when I rebooted the system, it started all the way up.

I was able to get the Odin to work and pass......I unplugged and it rebooted on its own, however, it would get to the logo, then Sprint logo screen, then show the dialogue "optimizing android apps"......but reboot again, same process over and over........never could get it to power off. I would do the combination of button presses for recovery and wouldn't work no matter how many times I tried. I could do the button presses to get to downloader mode and then once I hit cancel, it would go back to the reboot loop again. I even went to a nearby Sprint store and the techie there did the same as me, no success. He recommended that I take to one of the repair Sprint stores since they have the capability to connect it to a computer. I ended up going back home and trying some more. Finally, after six hours of phone not able to boot correctly, I got it into recovery mode. I had started hitting the Bixby button repeatedly with either volume up or down pressed at the same time..........then while still hitting the Bixby button, I pressed the volume up/down buttons and held them both down at the same time..............then viola, recovery mode! I was able from that point to apply the DRL7 update that was already on my device.......so finally got back up and running. Very thankful I got it back up in time because when it did boot up, battery was down to 13%............if the battery had drained completely, not sure what I could have done.
