Thanks sincerely for all the guides you made.

Not easy on 4.7.16

Hi, I am now in struggling with the updated KK. The smart flip cover works as it should.

The problem is: "Insufficient storage space available in System partition", as biobio76 told already.

I could not even install pa_gapps-modular-micro-4.4.2-20140608-signed.zip

Now I restored Play Store apk, via MyBackupPro, and now it connected me to Google.
[Device Reviews and Information] esipoko:
I converted G750-U10 to G750-T00!

No splash and boot screen but works totally fine.

I restored NVRAM and everything is good!

Pars Microtel contact me!
[Device Reviews and Information] biobio76:
cool

now, don't really understood how you upgrade, but I suggest you to follow my guide, since you have already THE NVRAM BACKUP (. bin and. tar) you can reflash everything from zero, bootloader is unlocked now so follow strictly my guide (format all + download), then UPGRADE TO 4.7.1._16 via ota... then complete the rest of steps in my guide....and you get the most updated firmware for your NEW T00

cheers

I tried to flash this greek B113 firmware to turn back to G750-U10 but errors happens.

brom error s_ft_download_fail (4008)

Second question:

I've extracted the rom files from UPDATE.APP with Huawei Extractor, how can I build a scratch file to flash?

What is verlist.img and curver.img?

Where is preloader and secro file?

I flashed Extracted B112 rom in combination with B609 stock rom and then upgrade through SD to B113 but I still have above questions.

None of SIM Cards detected and NVRAM restore has no effect.

---------- Post added at 04:43 AM ---------- Previous post was at 04:31 AM ----------

What do you mean by 4th step?

Where is Kitkat?

---------- Post added at 05:33 AM ---------- Previous post was at 04:43 AM ----------

Some results of my tests:

1. Greek B113 firmware is only flashed through local update from mSD card and phone will have no IMEI after boot and NVRAM restore is no use.

2. T00 firmwares has no logo, boot, recovery and battery charging screen but NVRAM restore make SIMs usable.

So please provide me with solution to:

1. Make SIM cards usable after Greek B113 or stock B112 firmware update.

2. Make logo, boot, recovery and battery charging screen visible in T00 firmwares.

Have you tried the solutions from posts #966 or #987?
[Device Reviews and Information] pavel22:
To sim cards were visible-should delete the folder on the way NVRAM date / nvram and reboot
[Device Reviews and Information] alexw801:
No, I haven't tried #969 nor #987.

What I did:

Copy to SD card:

renameddload/UPDATE.APP (extracted EMUI2.3_G750-T00_4.7.16.zip)

UPDATE-SuperSU-v1.99r3.zip

MyBackupPro.apk

pa_gapps-modular-micro-4.4.2-20140608-signed.zip.

Boot in Stock Recovery, wipe data/ factory reset + wipe cache.

(When you boot into Stock Recovery by long pressing all 3 buttons, it begins system local update if there is a dload/UPDATE.APP folder on SD and you can not wipe/reset)

By file browser rename on SD card:

dload/UPDATE.APP

Settings / Updates / System updates / Local update.

Boot in Stock Recovery, wipe data/ factory reset + wipe cache.

Copy SP_Flash_Tool_v5.1348.00 on PC in a folder. Copy Scatter file there. Copy the recovery file (it is the CWM Recovery by rua1) also there, unpack and rename as “recovery.img” (5870 kB), Run the SP_F_T as administrator. Open Scatter file. Only “Recovery” to tick! Push “Download”. The battery pull out and return to the phone. Connect the phone by USB cable, it works quickly.

Reboot to CWM Recovery

and make a backup,

and “Install zip from SD card”:

UPDATE-SuperSU-v1.99r3.zip

pa_gapps-modular-mini-4.4.2-20140608-signed.zip

Here it fails by „Insufficient storage space available in System partition” message.

Install MyBackupPro.apk.

Restore apk-s by MayBAckupPro (which you have backuped earlier).

The result is:

New google maps version on play store. Don't have proper connection to download right now, but hopefully will fix our FC issue
[Device Reviews and Information] tzivas31:
can i ask something to see if it happens to all or only on me? When they call to both cards it shows like they call me only in one and i talk but to the second number tells them that i have the phone off. When i have finished the call it comes an sms that tells me that they call me in the second number. Can work somehow to call me in both numbers and i choose the one to have it stanby until i talk to the other? Because it's not good the others thinks that you have your phone off. Thank you for any help
[Device Reviews and Information] Pelrauns:
Sorry to say that's not possible. While both sims are active while in standby, only one can operate the radio at a time. That means that when you are talking through one of them the other will look as turned off. This is the case with our phone and most dual simm ones.

Problem with b143 update

Hello,

I'm trying to OTA upgrade from B137 to B143, but unfortunately phone keeps reporting error apply_patch_check("/system/delapp/Weibo.apk"

Copy dload folder to external SDCARD root

Try Settings > Update > Local Update
[Device Reviews and Information] biobio76:
did you play with uninstalling apks ah?? :)

is your phone rooted?

guess you removed the root for trying the OTA right?

root it again, download the full delapp folder of the original: G750-T00_EmotionUI_2.0_V100R001CHNC00B137

delapp_B137.zip ( tot 92.1 MB )

https://mega.co.nz/#!olozlAYC!HnS8zMxkZc_oAxo8fdxEWL9nlDxDJD24CDKjLxVcZCU

extract the folder and copy the apks inside your system/delapp replacing the existing one...

set permission on all apks as RW-R-R with rootexplorer or similar tool

reboot the phone to check apks are re-installed again ( you should see then weibo etc etc )

romove root

remove CWM recovery

OTA upgrade and this time you will get it...

cheers
[Device Reviews and Information] Griso502:

When there is a dload folder on external SDCARD root with UPDATE.APP inside, you can switch off the phone, and for long time hold all 3 buttons pressed, so you enter into Stock Recovery, and it starts the process immediately.

Dear biobio

I wasn't able to upgrade through official greek B113 version but unlock part worked and able me to flash after that I was able to flash stock B609 of t00 variation.

Because I've decided to give the phone to my friend, I would flash it with Greek B113 firmware through local update but it was impossible cause it was a T00 now and SP tool flash was unsuccessful too.

So I extracted G750-U10 B112 files with Huawei update extractor and used B609 stock firmware scratch files and replace most of them with B112 files except Preloader, Secro and UBOOT.

After that I had a G750-U10 B112 phone and flashed B113 through local update.

Lots of problem happened with IMEI and I used alot of tools to fix.

If happened to somebody I'll explain it in detail.

---------- Post added at 06:22 PM ---------- Previous post was at 05:31 PM ----------

There are some complicated problems with IMEI that's beyond deleting NVRAM folder and Restoring NVRAM backup.

Update from 4.7.1 to 4.7.16, how I did

Copy to SD card:

renameddload/UPDATE.APP (extracted EMUI2.3_G750-T00_4.7.16.zip)

UPDATE-SuperSU-v1.99r3.zip

Gapps-KitKat_4.4.2_softpackage.zip.	(by biobio76)

Boot into Stock Recovery, wipe data/ factory reset + wipe cache.

(When you boot into Stock Recovery by long pressing all 3 buttons, it begins system local update if there is a dload/UPDATE.APP folder on SD card and you cannot wipe/reset)

By file browser rename on SD card:

dload/UPDATE.APP

You can do: Settings / Updates / System updates / Local update.

Alternative way: switch off the phone, boot into Stock Recovery by long pressing all 3 buttons, it begins system local update automatically.

Boot into Stock Recovery, wipe data/ factory reset + wipe cache.

Copy SP_Flash_Tool_v5.1348.00 on PC in a folder. Copy Scatter file there. Copy the recovery file (it is the CWM Recovery by rua1) also there, unpack and rename as “recovery.img” (5870 kB), Run the SP_F_T as administrator. Open Scatter file. Only “Recovery” to tick! Push “Download”. The battery pull out and return to the phone. Connect the phone by USB cable, it works quickly.

Reboot to CWM Recovery

and make a backup,

and “Install zip from SD card”:

Hi all,

I'm on the last KitKat firmware (Thanks to [MENTION=5132793]biobio76[/MENTION] instructions [emoji6]) with my Chinese G750-T00. But I'm facing some problems aside the (in)famous Google Maps crash.

I find that push notifications in apps like Whatsapp, Gmail or Tapatalk sometimes are not received until I open the application. I've allowed the app to stay open, switched to 'normal' power profile, disabled WiFi power optimizations, set up mobile data to "always connected"... And the problem is still there. Anyone noticed this? Anyone was able to solve it?

I think I'll wait for the Ascend G750 KitKat firmware to reach the Italian channel (I think that's the one with Spanish language) then turn my t00 to an Italian u10.

Thanks to you all!
[Device Reviews and Information] dancrow:
Using KK for two days and everything is fine.

To free up some system space is it ok to move delapp directory from /system root to another location, let say external sd card?

This will free up almost 200 Mb.
[Device Reviews and Information] biobio76:
Hi Pelrauns

Did you install the new firmware from a new clean installation as per my guide?

Map is not crashing to me.... Maybe because of the fresh clean installation or maybe it's scared ?

Anyway, it's true, the general chat pushing is sometimes not responding as due.. As well as the Gmail pushing... It's something I noticed still with JB firmware.... Guess it's the radio mounted on this device who is not always performing well.... I thought was happening in Italy only since nobody never notified this... (I'm Italian too)

Don't really understand what you expect from a U10 firmware.. Where all owners having this notified a lot of bugs and looking for move to T00...

Thanks ciao

---------- Post added at 10:10 PM ---------- Previous post was at 10:05 PM ----------

You can't....

You can't move... You can uninstall some apks who are in that folder

To free even more space you can (using titanium pro) convert a lot of system apks to user apks, example the music app, video app, and others can be moved as user apks and system will stay stable

Cheers
[Device Reviews and Information] Pelrauns:
Hi [MENTION=5132793]biobio76[/MENTION],

Not exactly at first. I tried OTA and apparently suceeded, but the phone entered a bootloop after the second reboot. Then I tried to flash CWM recovery and with the latest version of SPF the phone got bricked. Then I used the Chinese recovery program you provided and was able to restore the bootloader and perform a clean installation. Then I followed the rest of your instructions. So yes[emoji1], mine was an unwillingly clean install.

Do you use Google Maps often? With this firmware the app doesn't crash right away. So is easy to wrongly report it to work. However it crashes after you spend some minutes interacting with it, every time you do.

My grand-grandfather was in fact Italian but he came to Spain on a business trip, married my grand-grandmother and never left, so I'm Spanish. The reason to install an U10 ROM is for best integration with European services. I'm aware of the bugs they have, that's why I'm waiting for the KitKat firmware to be pushed to the European channels. I think the Italian one will fit me because normally Amazon sells phones to Spain from Germany, but the G750s are coming from Italy instead. I think is because of the languages included, so I'll go for the Italian one.

In the meantime I'll move some apps from the /system partition and try to install the full Google Apps package and check if the behavior of the phone improves.

Thanks for all. [emoji6] Ciao!
[Device Reviews and Information] biobio76:
Maybe it's as you said, I don't really use map often, I tried it a couple of kilometers while driving yesterday and was perfect, the GPS also fix in a second and very well, with kitkat they improved the GPS fix....

Will go out of city tomorrow so I will use it to test and revert my final feedback. I usually use TomTom apk and instead I can confirmed it's working well

Don't think the U10 will increase the way whatsapp or Gmail are pushing data or activate once one message it's received.... The phone is great but it's anyway a medium range phone, so the components itself can't be compared with other phones.... this can be simply a limit (hardware or software wise)

So, gracias!
[Device Reviews and Information] dancrow:
What I miss in KK is the option to set default SIM card for call phone and SMS . Do you know a way to fix this?
[Device Reviews and Information] Pelrauns:
No way to do it as long as I know. Given some of the features lost with the KitKat update (like DLNA for instance) I figure that the developer team are focusing in stability of the new firmware. After that I hope they move into porting functionalities from the old ROMs.

I've also download some KitKat updates for other phones (like the P6) that also feature emui 2.3. I plan to try to deodex some of the apps missing in our T00s and try to install them. Unfortunately those are single-SIM phones so the default card settings won't be there.
[Device Reviews and Information] passtheflask:
Thanks for the detailed post on upgrading to 4.4.2 biobio, however I've found I get the dreaded google maps crash after updating. I previously used another rom (I think it was B142) you uploaded here and I had no issues on this.

It opens and after about 2 minutes of navigation the app will just close itself.

I have rolled back to maps 6.81 since and had no issues with this version

Hi

I managed to upgrade my G750-U10 from B112 to B113. Flashing 4.7.16 with SP flash dosn't work. It starts downloading some file then phone reboots and SP flash tools fails. Tried SD update but it fails also. Do I need to convert phone to G750-T00 before? How can I do that?
[Device Reviews and Information] biobio76:

I've made scatter file by MTK Droid tools and download stock recovery from previous posts. What making a problem? Bad version od SP flash (i have 5.1409.03) or maybe some problems with recovery.img or scatter file? Maybe I should remove root first?
[Device Reviews and Information] dancrow:

[Device Reviews and Information] biobio76:
already provided explaination and solution on my post #647

http://xdaforums.com/showpost.php?p=53010118&postcount=647

you must load the rom I created ( you can do with B609 of my post 647 ) or

use kitkat rom directly ( my post 985 ) http://xdaforums.com/showpost.php?p=53968943&postcount=985

use format all + download on sp flash tool...

SPFT will format the blocks, then flash and install the rom...this will fix the PMT errors....otherwise you are no more able to use sp flash tool

Ive tried with 5.13 version and all fine. Have stock recovery. :) now unroot and try with ota update.

As I am lazy, I always replace the CWM Recovery with Stock Recovery by Mobileuncle Tools. In this phase the phone is yet rooted. I copy recovery.img to the root of the SD card, and then use Mobileuncle Tools.

I try to avoid using SP Flash Tool, I reduce it to the minimum.
[Device Reviews and Information] biobio76:
don't follow you ..??

again, which is your issue? the PMT error?

PMT error you solved with a clear flash of the phone ( formatt all + download ), full stop.

than, you will have a preatty new rom install, fresh installation, will all apps installed.

if your issue is another please excplain to me becasue I don't follow you now...
[Device Reviews and Information] luznykolo:
Sorry Sorry. Now pure English.

1) Back to stock recovery = done (with SP v5.13) no PMT error anymore

2) Try to OTA update after point 1 = fail because its some problem with HWeather.apk (maybe i've deleted it someday).

3) Checked this "delapp" folder you have posted earlier to find this HWeather.apk and there is no this .apk in there.

4) Now im stuck. OTA update fail :(

It's time to prepare clean installation with SP Flash Tool I think.
[Device Reviews and Information] biobio76:
which delapp forlder ( that you said I posted ) are you checking???

HWeather.apk is not into any delapp...you removed it by yourself from system/app....so there you must put it back...nothing to do with delapp

what else you removed?? you know this or not? because if you don't know what you did and are you doing ...it's better you flash rom preatty new.

cheers
[Device Reviews and Information] luznykolo:
Really i dont remember but i know that i ve removed some chineese apps and i think that will be many problems with OTA update because my phone its too much custom now.

I think i will try clean install with your tutorial. I think its the best way now.
[Device Reviews and Information] biobio76:
exactly what I suggested since the beginning.

Be sure

to have NVARAM files backed up prior to start ( the *.bin and the *.tar ) - use mtk droid tool v2.5.3 to back up those .

then follow stricly my procedures and the order I post the step by step.

in case of need let me know.

You can also try to upgrade via local update option. Make sure you have dload\update.app folder on root of external sdcard.

OR :

Second option : put dload\update.app folder on external sdcard, shutdown phone, press vol up & vol down & power buttons. The phone will enter in sdcard upgrade mode. Be sure you are unrooted and stock recovery.
