[Q] U8800 CM 10.1 trouble

Hey guys, so this happened to me. After following the guide to install cm 10.1 i got a boot loop, and somehow when i got back to recovery mode 5.0.2.7 my sd card wasnt being recognized, i couldnt connect my phone to pc ( unable to write to ums lunfile ) and i also couldn't mount sd-ext, wich means that i'm stuck in recovery.
I even tried pink screen, but win7 doesnt install the drivers, so i can't copy any new rom to my phone to bring it back to life.
So what can i do?.... im tired of searching an nothing.
(sorry for my english)

Try connecting the phone to a Linux distro, Ubuntu for example. No drivers are needed and you can access the phone via pink screen and a sudo nautilus window
Cheers

You can try to ask someone to give you the drivers and then force install them while connected to pink screen. OR you can connect your phone while got are in recovery and if your computer recognizes phone then push a ROM through adb.

i have already tried to mount the phone with recovery but it doesnt allow me :\

You have flashed previously an official 2.3 rom which has pink screen locked, so you cannot access to the partitions. Linux cannot help you on this.
So if you haven't access to sdcard or to adb, then the only think you can do is to reinstall the official rom. But this time do these 2 more steps which are life savers:
1. Flash the unlocked bootloader. There is a thread on U8800' s forums: "get your pink screen back"(maybe the name isn't exactly this but you will find it using search function). This will flash the B518 bootloader which is the last unlocked. All next version of official rom have the bootloader locked.
2. Make a full backup of the device from linux. There is also a thread for this: U8800 full Linux backup how to
Then you will have the way to recover your device from almost everything.
Also to flash CM10.1 you need larger /system partition. This was the reason of bootloop. There are infos about this on CM10.1 thread on general section.

You don't need it just remove your sd and put on another phone or SD reader and copy files to micro-sd then you can update...
My advice: official rom, root, CWM recovery then update to any custom rom.

but how can i update if the phone isnt reading sd?

This happens in recovery mode. This isn' t a general sdcard fault. The update mode is different and I don't thing that you have problems with sd there.

No you cannot use bootloader.zip on upgrade mode.
You must install the official rom from upgrade mode as you did the first time.
Then first you must root the phone, flash the custom recovery and after flash the bootloader.zip from there.

You have to rename the update.app from step 2 to update_cust.app I THINK.

Forget maybe isn't necessary. But you need to put that files on root then hit Volume keys + and - and Power button if doesn't work can you tell me what appears on pink screen when you hit that combination of keys.

Can't Update Axon 7 (USA Version)...Stuck on B20

Hello,
Wondering if anyone can offer some advice. Just got an Axon 7. Was on B27...HiFi settings had a weird buzzing sound when set to "super". Thought maybe I should see if there was an update, but phone just said "Please check your network connection". My wifi was working fine and tried factory resetting multiple times. Finally I downloaded the update.zip off the ZTE USA site that was for B20....thought maybe I could downgrade to B20 and then update to B29, but no luck. Now I am stuck on B20 and still getting the "Please check your network connection". Can do anything data/wifi needed except update. Any thoughts? Phone is non-rooted....haven't even had it long enough to think about it or have time yet.

You can also sideload the OTAs. Put these on your microSD card.
B27 OTA: https://dl1.ztems.com/zxmdmp/downlo...ZTE A2017U/81526/update_P996A01_B20_to_B27.up
B29 OTA: https://dl1.ztems.com/zxmdmp/downlo...ZTE A2017U/82082/update_P996A01_B27_to_B29.up
After you put them on your microSD card, they might show up in the System Update menu, I'm not sure.
If they don't, you can flash them via stock recovery. Rename them to "update1.zip" and "update2.zip" or whatever, boot into stock recovery, flash the first one, reboot into the device to make sure it flashed fine, reboot into stock recovery, flash the second one, reboot and you should be on B29.

Hmm...thank you for these! This is the kind of solution I have been hoping for, but they didn't show up in the updater and when I tried stock recovery it said "can't update from sd card".

1- IMPORTANT - enable OEM Unlock under Developer Options ( THIS IS NEEDED IF YOU WANT TO USE THOSE FILE WITH STOCK RECOVERY )
2- change the extension from .up to .zip
3- Move Files to SDCard
4- Boot to Stock Recovery and use UPDATE VIA SDCARD

Keep in mind that the links and such in this topic are for the US model, the A2017U. You have the global model, the A2017G.

Can any of you upload stock B20 for the a2017u? The link posted by tenfar isn't working and the file hosted on Mega's site is going to take too long to download due to not having a paid subscription?

help me unbricked Huawei nexus 6p

hello friends,
i unlocked my bootloader and flashed a custom Rom. i was experiencing problems and i decided to revert to stock google rom, i mistakenly locked the bootloader with twrp recovery installed and i now get the message that my phone is corrupt and cannot be trusted. The phone doesn't boot it stucksat the Google logo. I the tried unlocking but not successful,
is there any help for me? thanks in advance

Dont wanna be the bad news guy but I think you broke your device.
You can't do anything in the bootloader now. Try to do stuff in TWRP. If TWRP still functions normally we can do something.

Hi.
Go to:
http://www.androidbrick.com/download/unbrick-nexus-6p-angler/
And follow that guide ?

If it boots up just boot it. I face this corruption screen every day on 5X, I also have locked bootloader with TWRP onboard and no issues so far (stop talking bull**** that this will brick device, btw).
You said it can't read internal memory. What exactly it display (I assume it can't decrypt it)
Try to sideload random ROM and install it, then toggle OEM unlock.

I see no other option than full wipe and reflashing stock. So your data will be gone
Format /data in TWRP,
Reboot recovery,
Put any stock system image you have (system vendor, boot, recovery) to internal storage. (I assume you have at least one factory image on PC if not download),
Flash them in recovery (flash recovery last just in case)
Device SHOULD boot up.

I also tried to change my stock rom to custom rom. I don't know what happened, only twrp3_1_1_4Cores.img works on my device. I can install a custom rom but it doesn't boot into it. I cannot find any further informations about it. Can someone help me?

Looking for EMUI 5 (VNS-L21)

Hello, i’m looking for the update file for my phone. I’m currently on EMUI 4.1, to which i foolishly downgraded to last weekend. I would like to update with the SD Card and dload folder method, but i can’t find the stock EMUI 5 rom anywhere.

Thanks, i tried method 3 first but it failed (i have an unlocked bootloader though), so then i tried method 1 (i had twrp from meticulus already installed) first went to install only the update.zip in twrp, it failed, but when i rebooted, the phone is now updated to emui 5. Also my build number is now the test keys nonsense, but that happened to me before and i know how to fix that.

Install TWRP for Nougat, e.g. this one:
3.1.0.2
Install it over eRecovery with command
fastboot flash recovery2 xxxxxxx.img
Copy to the SD card the second file - hw_eu.zip from B370.
Boot into TWRP, click WIPE, then FORMAT DATA , after REBOOT SYSTEM.
The smartphone will start rebooting: as soon as the technical menu appears on the screen (yellow warning) press and hold Volume Up up to 3 sec, and here you are in TWRP again.
Click INSTALL and flash update_data_full_VNS-L21_hw_eu.zip.
Reboot into stock Recovery and do factory reset.
