Do you have any solution or comment?
[Huawei Ascend P7] zaabolla:
because you are from middle east you should have install B853, it's equal of B852 for europe region
[Huawei Ascend P7] zaabolla:
you should pass by B621 first

second flash europe cust

third flash b852
[Huawei Ascend P7] tommykole96:
Do i Flash 621 over my stock kitkat or over transition package? And where I can find cust fix?
[Huawei Ascend P7] meysamazizi:
I loaded B853 and every details are in best condition.

thanks a lot
[Huawei Ascend P7] zaabolla:
if you are still on ktkat no need for b800, only on lollipop to downgrade

cust fix is in the same archive with b621
[Huawei Ascend P7] tommykole96:
Great, one last question: Do I Flash cust fix before or after update?
[Huawei Ascend P7] zaabolla:
1/ if you're on lollipop flash b800 first

2/ flash b621

3/ flash cust europe ( here all your data will be lost, make backup first )

4/ flash b852

I have the Huawei Ascend P7, was using Android 4.4.2, so I decided to update the phone, I followed a tutorial that taught me to do the BACKUP using Huawei app, and then selected the update file in the same app. Update failed in 98% at that time my nightmare began.

My phone started BOOTLOOP.

My steps:

I downloaded the initial ROM website huawei: http://consumer.huawei.com/my/support/downloads/detail/index.htm?id=37501&key4=p7

Follow this post: http://xdaforums.com/showpost.php?p=56074149&postcount=4

All have the same problem, and I tried with all ROMS I found on the internet.

I installed TWRP using the fastboot, however did not help me much, the TWRP has been my only functional system. :(

I have the factory version and any version I want to work, I believe the version I had was: Sophia-L10, Android 4.4.2, EMUI 2.3, V100R001C00B134SP05
[Huawei Ascend P7] vd1122:
You must change your cust. Search xda for that. For b852 version, you must have cust c432d001. This is cust for b852! :)
[Huawei Ascend P7] Tippfehler:
You should use stockrecovery. TWRP will not work.
[Huawei Ascend P7] l3Nni:
Try to flash Se7en-Rom 1.x through twrp, then the stock emui 2.3 recovery per adb and force an update with any B1xx based stock rom (hold power, volume+ and volume-). Now you should be able to update the normal way up to lollipop.
[Huawei Ascend P7] Reyse:
Hi!

was your phone rooted? Was your phone in stock recovery?
[Huawei Ascend P7] liwston:
Where do I find the download?

Where do I find the download?

Yes. Before entering BOOTLOOP was with the factory version.
[Huawei Ascend P7] Tippfehler:
You can extract it from the full update.app (~2GB).
[Huawei Ascend P7] liwston:
boycracked.com/2016/04/12/official-huawei-ascend-p7-p7-l10-sophia-l10-stock-rom-firmware/

this site has several ROMS, which of these we extract the recovery.img?

...then which one I will use to force update?
[Huawei Ascend P7] Tippfehler:
Try the newest, if not working, try the older ones.
[Huawei Ascend P7] l3Nni:
You need to use a rom based on emui2.3 and kitkat, so, every full B1xx rom will work. Do not use a newer rom, the recovery is definitely not compatible to different emui versions!

Beside that use twrp 2.8.1.0 (http://xdaforums.com/ascend-p7/development/recovery-t2811965) and Se7en-Rom 1.6 (http://xdaforums.com/devdb/project/?id=6290#downloads)
[Huawei Ascend P7] liwston:
from here boycracked.com/2016/04/12/official-huawei-ascend-p7-p7-l10-sophia-l10-stock-rom-firmware/

I extracted recovery from C00B619, and put recovery with fastboot....

I try force update:

- C900B861 = Fail;

- C900B853 = Fail;

- C00B619 = Fail;

- C00B121 = Fail;

- C00B123 = Fail;

- C02B125 = Fail;
[Huawei Ascend P7] l3Nni:
Try going the step over a custom rom like I described a couple of posts ago. Most of the time this will fix the problem.

The B619 recovery cannot work.
[Huawei Ascend P7] liwston:
I try this rom: boycracked.com/2016/05/04/miui-v7-huawei-ascend-p7, installed from TWRP and... I got BOOTLOOP again
[Huawei Ascend P7] l3Nni:
Ahh, Miui is based on the eastern L00/L03 version of the P7, this probably caused problems. Please try the Se7en-Rom I linked.

Edit: I looked at the link, the rom is based on lollipop. You need a kitkat emui 2.3 based (B1xx) custom rom for a L10 device.

[Huawei Ascend P7] kaha6uc:
I'm sorry, but I think that TWRP will not be able to apply the UPDATE.APP file :(

You'll need to force-update it. Place the UPDATE.APP on the sd-card in /dload/ directory, insert the card in a powered-OFF phone and boot it while holding both volume UP AND DOWN buttons.

Let me know if it works.

Hi

I have tried to upgrade to B852 by "air" - phone detected new version and suggested to update (as usual). After update I got bootloop :(. After several "forced (3 buttons)" updates - no results :(. So I have come back to B623 (cust c432D001) - but any time I try to install B852 - I run into bootloop. Phone is not rooted, all updates only from Manufacturer by "air" updates was done. Someone have ideas how to upgrade to lillipop?
[Huawei Ascend P7] RangerP7:
Did you try factory reset after upgrade?
[Huawei Ascend P7] Giedriusd:
Yes, I did factory upgrade, also clear cash. I reapeted sever times - also reset to factory defaults before upgrade and after. But, what I found today: when I install B623, which works, I phone has one issue - if I try to open camera (or snapchat, which accesses camera), phone crashes to FASTBOOT&RESCUE MODE white screen. So, maybe my issue is related to this malfunction and it is hardware, not software problem and that is why I have bootloop with B852 installed :( ?. Any ideas how to detect problem or what other actions to do?

I worked through this thread, but I'm quite confused, so I hope I can get some advise.

Years ago, I installed MyRom1.2 on my P7-L10 with TWRP. I want to upgrade to the 5.1.1. firmware in this thread. I tried the "ease way" with a local update, but this results in a halt in the TWRP start screen. So probably I need to do something else...

- Back to a stock rom: I looked for this, but I cannot find a stock rom that I can install with TWRP (after which I hope to be able to update easy)

- I read all kind of Bxxx versions, I have no clue what kind of Bxxx number I have

- My CustId = CUSTC432D135, I read in some messages I have to change this, but I have no clue why and how

So, how to proceed? Really appreciate your help!

SOLVED: Software install failed!

Tried doing a forced upgrade (vol up + vol down + power) from P7-L10V100R001C00B623, EMUI 3.0, CUSTC432D001 to B852 (as per Carbontesla). It failed with "Software install failed! Get help from <some url>/emotiondownload.php?mod=restore" (which is completely useless) at around 19% completion.

I then went on to do a factory reset/wipe data + wipe cache partition and tried the upgrade again, but this time doing a normal upgrade (Settings->Updater->Menu->Local upgrade->Confirm->Upgrade). However, before doing that I copied the UPDATE.APP file again and this time it took significantly longer than the first time. I suspect that the initial copy was interrupted somehow and that the factory reset did not really have an effect. Anyway, after letting it do it's thing the P7 now is at 5.1.1.

Try to download and flash B832 (I think it's that one) first.

It should be on xda somewhere.

? Oh - I've seen what you've done... You've tried to jump straight from B116!

Can't do that. Do in this order:

1. Flash B621 kit kat full

2. Flash B830 full

3. Flash B839 full Sophia

4. Flash B852 full

All can be found here on xda but it's better to get them all in one place at:

Huaweiblog.de

It's German - use translate if you want to read but you don't have to.

Just download these firmwares and flash in order.

It's a good site, very organised, everything is there.

Make sure you have a clean sd Card at least 16gb because these are all about 2gb.

[MENTION=3708017]almir1984[/MENTION]

Ok, good - is changed the base system.

Now go ahead and flash B852 full.

This is the last official release ROM from Huawei for this phone.

You should now be on lollipop 5.1.1.

B840 is not stable....

Get the B852 you downloaded from here and flash that and you should be good.

Understand you have now moved from Kitkat 4.4 to lollipop 5 - is a completely new system so your experience will be very different from what you were on with B116.

When you've flashed B852 from here, you might get an update from Huawei official to B853 which is an update to security systems and for some smoothness.

What are you on at the moment?

You don't need to root but you need to go from the 6 series, to B840 then to B852.

Just flash them normally in that order and you'll be fine.... You may even get an OTA to B853 if you check software updates after you've flashed B852

Dears,

Need your help.

I'd been trying and searching around for 3 days but no solutions to my problem.

What happeded was:

- There was a firmware update (OTA) and when i try to do updating, my P7 L10 went into a black muted screen for hours. So, i have to manually reboot my phone. And informed me the firmware updated failed!.

What i did was:

- Found out about extracting .img files and flashing using adb tool.

- So, i extracted boot.img and recovery.img from the one (dumb enough that i didn't check.) i downloaded from somewhere from the web.

- And i was able to flash them via adb tool in fastboot mode.

- After successfully flashing them, the phone wakes up in EMUI screen.

- From that onward whenever i reboot the phone, it will always wake up on that screen.

- When i charge the phone, it will awake and keep staying on Huawei Ascend logo splash screen.

Well, as u can see i'm pretty stupid and very regret what i've done to my asend p7 L10.

Hopefully someone here can rescue me...

And power off yr phone>> connect the usb cable>> press and hold 3 buttons Vol-, Vol+ and power.

Yr phone will be in black muted for a few secs. During that period type below commands in cmd where all your img files locate.

adb devices

fastboot devices

fastboot flash boot boot.img

fastboot flash recovery recovery.img

fastboot flash system system.img

fastboot reboot

1st reboot didn't succeed. Somehow i did manually reboot 4 to 5 times with usb connected to the pc.

And suddenly voila android 4.4.2 screen showed up.:)
