USB-OTG not working - Huawei P20 Pro Questions & Answers

Hello!
2 pcs P20 Pro (now servicing). Tested 10 and 9 version, not read OTG (in system or in recovery).
Now offline (not PC) update from SD available only... this phone not support SD-Card! Only OTG-SD.
-Attached 3 other USB-OTG converter cable (1pcs new, 1pcs 20x used)
-Attached pendrive (exFAT, FAT32, NTFS)
-Attached SD (exFAT, FAT32) in Kingston USB-SD converter
Pendrive LED not on: not readed.
Tested OTG cable to other USB device, 5V ok, Data line voltage ok: USB all 4 pin ok!
Tested OTG cables other older droid 5.1 phone, all working, SD readed with converter, pendrive readed correctly.
One P20 Pro bricked. Bootloader locked, fastboot mode available only (screen blank), Multi-Tool flasher/unbricker "stock service flash" downloaded to phone and failed (no write permission). Hisuite not support this phone recovery. No other method to unbrick, only SD-update. How to working this port?
Live system not read OTG and bricked system not read OTG.
Live system developer mode settings (*#*#2846579#*#*) changed to default, Manufactture, Hisuite, same. Developer software upgrade: 1. Memory card, 2. APK standalone, not available OTG/USB. Connected to PC: Photo mode, File mode and Charging mode available only (not available reverse charge).
USB port measurement: not powered live system, booting, recovery "update OTG mode" not powered the USB port!
1 phone= inside cable USB to mainboard bad? 2 phone= 2 cable bad??? Not real!
Charging ok. PC connection ok.
What is a problem???

Hey Looking Forward To Help You..
1.Go To "SETTINGS"
2.Search For "OTG"
3.Some Phones Like Eg.Oneplus Have OTG Option In the Status Bar Customisation Tab..
4.Use An Prober Cable [OR] See If It Works On The Other Phone..
5.Important The Drive/SD You're Using Doesn't Have Any Hardware Issues!
6.Best Thing Is Two Option.
A.Software Update.
B.Factory Reset - Data Loss [Not Recommended]
7.Or It Must Be an Hardware Issue Please Reach Out To The Nearest Mobile Service Centre.

If not rooted, use PC with Hisuite official software.
If not communicated to phone, need to reflash manually. This is not free.
In DC-Unlocker site download 2 software + pay 3 day license for this softwares and use.
Bootloop and cracking not related!
Cleared chaches??? Not solve?

Done factory erase,done cache memory erase,done restart and just staying on the Huawei screen where is saying down at the bottom Powered by Android for few minutes and after that goes in to the white meniu where you can select factory reset,updates (tried the WiFi update is not connecting),now I got the firmware and Kiwibird 4 in 1 card reader that you can plug up the "ass " of the phone usingOTG hopefully I can install the firmware from there...I have downloaded the firmware and just putting it on the SD card...have you tried that way?

Firmware install not working "offline" mode.
TWRP and any other not read OTG, only live system.
Another problem: OTG only support FAT/FAT32, not supported NTFS, ExFAT (Live system: need Paragon software). The firmware file more than FAT32 filesize limit (2GB), only stored NTFS or ExFAT = FW file too large for FAT.
Your FW upload only 3 method.
1. Boot to recovery, and set ADB mode, download the FW zip to DLOAD dir (from PC with USB cable + ADB), and install. (NOT TESTED!)
2. Boot to recovery, and set wifi recovery. Connect to wifi AP, download latest downloadable FW and install. (NOT TESTED)
3. Paid method: DC-Unlocker & DC-Phoenix work with standard recovery (limited access) and work own uploaded recovery (self opened bootloader/virtual testpoint).
OTG/SD not option for FW update!

Thanks you for your time,and writing back to me,yes,good point with different types of partitions,I forgot about it...I did try the nr.2 method and is not working,it can't download anything,I have trying different wiFi points,not starting any download,it does connect to the WiFi but can't find anything to be downloaded.
First method is not going to work as I have no access to set ADB mode,only fastboot mode,and is displayed that phone is locked soo, bootloader is locked and can't open it...soo only method to try is theast one...but don't know how much will that cost me.
Also I am thinking of other people said that the battery can have a problem too as my battery is getting empty fast...also something strange maybe..but if you tap the phone on the upper side on the edge it's restarting itself...I am thinking to open it up and try like that as in the past had been dropped soo back glass and camera glass have been replaced,but was working,until I have done factory reset and the process got interrupted in the middle of it and that was it...since.then..Inhave tried reset, factory reset,wipe cache, nothing working.

The softwares for 3 day ~20$. The DC-unlocker site write correct actual price.
If bootloader not opened, only available FW-update in Hisuite Huawei official software.
Test in recovery mode or bootloader mode.
(My recovery is TWRP, not available recovery method. Your available.)
Test connect to phone this software! If yes, but not available firmware, need to use special VPN software. Download offline your phone firmware to PC, or set specified link to VPN soft and Hisuite: update available! (Need Hisuite downgrade for this VPN method.)
If this update not working, purchase 3day license.
Need offline firmware file for your phone.
Soft-bootloader open if not working, use testpoint. (The DC-Phoenix manual write the testpoint position.)
Start the process in PC, Short testpoint to GND and plug USB. (If need, install drivers.)
Started upload unlocked bootloader and unlocked old recovery. After finished, reboot to recovery. (Without accu, work end... after reboot only work with plugged accu.) (Not need unplug accu!)
After booted recovery, wait PC to identify recovery mode, and started download.
The download 2 part! 1= firmware, 2=cust file. Need all selecting!
The download automated. Please wait for 100%. After end, rebooted to system.
Check IMEI, phone signal, MAC numbers. All ok? End flashing.
Wrong or no IMEI, bad MAC? Need the second software.
The second software unlock bootloader, FRP lock, all lock.
Unlocking bootloader (not need): software say the unlocking number, phone boot bootloader, PC USB ADB (Fastboot) command need to write the code, phone question: yes? Is yes, rebooted to recovery and CLEAR ALL DATA! After cleraing, boot system.
All phone start displayed "Phone untrusted".
Unlocked bootloder = uploadable TWRP or any recovery, after not need testpoint to flash.
Root: only rootable 8.1 system. (Not tested 8.1+, bootloader code not readable.)

Hi there mate,I have manage.to fix my phone,just following an old post here,with one russian website,where I got the firmware,put it on the SD card ,by the way you can make it eXFat ,will work for larger sizes,mine was 128 GB,and had to reboot the phone in update mode but selecting OTG/SD and it worked first time!I manage to update it with Android 10.After that all good,done the updates up to 12.
Thank you for your support and time!
Have a great week!

8.1 (stock) System and recovery not compatibilie / not read ExFat.
I have 8.1 System (rootable). In 8.1 OTG/SD update not working.

Check your filesystems:
Code:
$ cat /proc/filesystems
...
msdos
vfat
exfat
...
(This is a different device.)

Yes, system ok... i was wrong.
TWRP recovery not read any OTG! Other version TWRP read OTG, and not read correctly system partitions (half phone not read).
Standard recovery not available for me to testing.

[Q] S3 LTE I9305 - Unable to boot, corrupt OS? and data recovery

Hi all,
I hope you can help as something very strange and unusual has happened to my Galaxy S3 LTE i9305 (on Orange in UK). Samsung technical support tell me they've not heard of the issue before as do the official repair shop. I have never installed any unusual software or tried to access the internals etc.
On Sat 26th Oct, in the evening, the phone was connected via USB to my laptop charging. There was no data transfer taking place, and the laptop was idle. The phone was not in use, nor was I nearby but randomly it showed the Samsung splash screen logo - it looked a little weird as it was pure black but with random speckles of coloured dots (which made it look like a Galaxy - I thought perhaps I hadn't noticed it before). I was unable to reset so took the battery out and replaced. It did the same thing and then on the second time of removing hte battery the screen became completely white with black marks generating a fuzzy effect - it's been like this ever since.
I get the white fuzzy screen if attempting to turn the phone on, or attempting to recovery mode, however if going to the install option (which I assume happens before Android boots), the screen is absolutely fine and proves not to be at fault. I should add the screen is cracked slightly, it has been since April and is not the cause of this random error.
Tech support tell me that they'll happily accept it back but ultimately, they will wipe the phone and send back as reconditioned. I've tried to connect via Kies, device not found - nor is it when connected to a computer - infact the computer tries to 'install device drivers'.
I'm sure everyone says this however I am an organiser of a large local festival in the UK and the phone has some very important detail storesd in the ColourNote app which I need to access - also the contacts appear not to have synced with GMail since May.... I'm desperate to access these files, for money too potentially, but cannot afford to go down the simple, wipe and reformat easy option. Can you help? Do you know any software that can access data from the internal memory card (note I've removed the external card which contained the photos) How about once the phone has been wiped, to try and see if anything can be recovered then.
Would really appreciate your support, this developer community is my last option and you're normally so awesome, as can't find any reference to the problem online.
Is your colour note app not synced ??
You can try RECUVA data recover.
You need to read the faqs and guides first .
Including the one that covers storage and recovery ..
Samsung reject warranty on phones that have damaged screen .

Hi,
....no I had never set it up. So ironic that was on the to do list in the app.
I'll look into Recuva, is that for before or after I send it off. Is there much chance do you think?
Yes, sorry. I meant to say I also have phone insurance which covers the screen so will have it off to them first, and then onto Samsung - ie 2 places of data wiping!
Thanks for your reply though,
Kind of hoping I may just be able to fix the problem, even if only temporary, but realise it's unlikely

Hi mate,
You can try flashing just the system (and boot) images if you think it's a software issue.
That way your data partition will be intact.
Instructions:
Step 1) Download the Stock ROM you want to use
Step 2) Rename the file from .tar.md5 to just .tar
Step 3) Open the .tar with WinRAR or something similar
Step 4) Extract: system.img (and boot.img if you want the Kernel)
Step 5) Create ODIN file from .img files http://forum.xda-developers.com/showthread.php?t=1484304
Step 6) Flash the new ODIN file to restore your firmware to Stock!
On Windows you can use Cygwin to run these commands if you don't have access to Linux.
NOTE 1: That guide uses recovery.img as an example but you can replace that text with system.img on the first line.
NOTE 2: If you are adding more than one file (eg. system.img & boot.img) simply list them one after the other with a space between each file.
NOTE 3: Do not include data.img, it WILL wipe your data! Do not include cache.img, hidden.img, these MAY wipe your data!
Best of luck, I hope this helps you out :fingers-crossed:
Have a great day!

So, here’s how you can recover data from a Soft-Bricked Android smartphone:
1. Once you’ve installed a custom recovery on your device, open it using the specific method for your device. E.g for Samsung you can turn off the device completely, then turn it on by pressing and holding Volume Up + Home + Power Key and you will be able to access the recovery. These methods vary for different devices.
2. Once in CWM or TWRP Recovery you will find a number of options.
For CWM Recovery, select “Mounts & Storage > Yes”.
In Mounts and Storage menu you will find some more options, from the list select “Mount USB Storage or the option depending upon your choice.”.
Now connect your phone to your PC using the data cable.
As soon as you connect your phone to your PC, the USB Storage / Internal Storage will open up in folder view.
You can copy all of your files to your PC now.
3. For TWRP Recovery, Select “Mount > USB Storage”.
Connect your phone to your PC and it will open up the USB / Internal Storage.
3. Copy your desired files.
That’s all! You can easily recovery all of your data stored on the internal storage of your Android device.

[Q] No Option to Update

Hello,
I've already sent my device back to Asus, where they did absolutely nothing and just sent it right back to me. Complete waste of $16 shipping.
anyway, a while back I received a notification to update firmware. It downloaded, but then the install failed. About 2 weeks later, it prompted me again, and once again it downloaded but then failed to install on the restart. I decided to download the latest firmware on the Asus website, but I have no option to install by SD Card once I'm in Droidboot. My only options are:
1. REBOOT
2. REBOOT DROIDBOOT
3. RECOVERY
4. POWER OFF
Can someone please help? Asus has been absolutely no help, as I just spent another hour yesterday "chatting" with the rep who knew absolutely nothing!
Thanks in advance, cheers!
Well, I guess I stumped everyone in here as well. I just sent the device back to Asus for the second time in 2 weeks. Let's see if they do anything more than just power on the device, deem it "working properly" and promptly send it back to me.

I have (2) K01A MemoPad 170CX's, less than 30-days old. Both updated to 4.4.2 via OTA method running software Image Version: V11.2.3.27. (2014-12-23)
On one all of the sudden (and it may be a case the camera never worked) is when the camera is activated the cam app comes up for (3) seconds with the still icon lit up, then the video icon lights up as well for a (1) second then app exits to desktop with a "No Camera is found" error message.
I've been all over the net trying to find into on how to manually flash it.
According to the very cryptic info on ASUS website step # states:
"2. Download device software and Update SOP (From “Manual” Item)"
Googling for info on SOP, you download firmware in zip format, then do (1) extraction of the contents to a MicroSD card formated FAT32 to the root of the card. (After extraction there is a zip file named ifwi.zip that contains (4) *.bin files that remain inside the zip, you don't extract that zip.)
According to info on SOP, with device powered fully up inserting the sd card is supposed to bring up a prompt, a icon on the taskbar/, you click the prompt and the update process begins.
I'm not seeing that.
All I see when the SD card is inserted is a notification the SD is being prepared for use.
When trying to update via DROIDBOOT (W Fastboot wording at bottom of screen), with SD card inserted the DROIDBOOT menu isn't coming up, when I fire up DROIDBOOT without the SD card inserted and insert it DROIDBOOT does not recognize any change has occurred.
Wanted to try re-flashing WW_V11.2.3.27 as I've read in cases the camera gets the No camera found error message the camera firmware gets corrupted somehow. when you hit the return to home-screen icon too fast, I guess when app is in process of opening and it's closed before it initializes fully.
If that doesn't work, trying Version WW_V11.2.3.28 as I for sure don't want to have to send the device back to ASUS when a simple reflash of the firmware would get the camera working again.
Q: Are / were you getting the same results?
(I guess you didn't try SOP method?)
Q: I guess "Fastboot" means "neutered"? Is there a way to bypass? /enable all functions ASUS would not be able to detect if I have to send in unit for service?
Tried copying the contents of the removable SD card to the internal SD card folder...
Nada, zip, nothing.
ASUS needs to provide info on how to run the flash, I've never had this much trouble flashing a device.

I tried everything under the sun....I extracted the zip, nothing. I left it as a zip, nothing. I went to recovery, nothing. You name it, I did it. So, I sent back to Asus for the second time in 2 weeks. I just checked the status of my RMA with Asus, and it states that "No trouble found." I'm not sure how NO TROUBLE IS FOUND when I can't even update to Asus latest firmware for their device? In addition, I do not get the options to try to manually update (Not that I should even have to go that route when it should be OTA). I will never own another Asus product. I've only had my tablet for 4 months, 2 1/2 months of which it sat in my desk, unused. Asus is garbage.

No I did not remove any system files or freeze them, that I know of. I rooted shortly after purchasing this, but unrooted the device about 2 weeks later.

If you are talking to me in which camera(s) both seem to not be found by the OS ME170 is STOCK, STOCK, STOCK.
Contacted the vendor TigerDirect, noticed that they claim they will NOT do exchanges due to "manufacturers polices". While I realize it costs vendor (TigerDirect) to handle exchanges that wording could also indicate they have run the numbers and don't want to be bothered.
Reading about ASUS service, and my interaction with ASUS when I contacted them does not insipre incidence so I'm hoping to be able to flash the device and cameras will start functioning again.
In regards to the customer being able to flash a device (Which I done numerous times on other brands)
I know ASUS is a Asian based manufacturer and sells worldwide but they really need to have persons who can write in better ENGLISH.. ASUS needs to publish detailed instructions on how to flash device, additionally they need to update support pages with any drivers, tools to do so vs just posting the firmware with vaque reference to SOP.
Q: How long after firmware updates appears on ASUS site does OTA update get pushed?
..
Just an update....
Just received my memo pad back, and it appears to be finally fixed. It took sending it back twice, and escalating to a supervisor, but it looks good now. I've actually received 3 firmware updates in 2 days, so it was REALLY behind! What firmware are you all running right now? I have WW-3.2.23.201.
I think 201 is the latest. Mine is still on 199 though and it won't try to update again since it failed a couple of weeks ago.

Stuck at "Press the Windows key" in recovery mode Windows

After installing the dual boot bios on my teclast air III (M5C5) I tried to install Windows. Unfortunately, just before completion the installation was cancelled because of the following error: "Windows could not update the computer's boot configuration. Installation cannot proceed."
If I start my tablet and choose Windows, I get the following Recovery page:
The boot configuration data file is missing some required information.
File:\BCD
Error code: 0x0c0000034
You'll need to use recovery tools, if you don't have them...
Press the WIndows key for UEFI Firmware Settings
Click to expand...
Click to collapse
Of course I've tried to press the Windows key, but nothing happens. I've tried all keys and several common combinations, but none of them did anything, except spamming Ctrl-Alt-Delete, which forced a shutdown.
I can enter the BIOS, but for some reason there's no option to select Boot from USB stick (only UEFI OS and Windows Boot Manager). The strange thing is that I've used this usb stick to install Windows on the tablet in the first place and I've tried both GPT and MBR and used a usb 2.0 stick in a 2.0 hub, so the usb stick shouldn't be the problem I guess.
But probably even worse is that I cannot get into DNX mode anymore, so I can't install Android either. If I try I get the following message (instead of " Waiting for fastboot commands" ):
BOM Selection Switch (SW1B1) has been changed, but cannot take action. system will reset in 3 seconds
Click to expand...
Click to collapse
For some reason there is not much information about this error message and I could not find solutions to a similar problem ("BOM selection switch SW1B1 has changed Force_Windows"). In a desperate attempt I've tried to enable fastboot in BIOS to see if that would make a difference, but it doesn't.
Any help is welcome, thanks in advance!
Are U sure you have flashed/installed the right BIOS/Firmware ? double check it !
Also if your USB drive is USB3.0 your hub must be 3.0 too OR you must connect the USB drive directly to the OTG cable.

It was a 2.0 drive in a 2.0 hub. But I've tried with a usb 3.0 stick in a 3.0 hub as well and that doesn't work either.
I've had some problems flashing the BIOS. Initially I tried the simple method using the UpdateIFWI app (using the Mirek V7 rom and downloaded the UpdateIFWI app seperately) with the bios "Dualboot Bios Tested C6J6 And C8J7" from here, but that didn't work. Then I used the Mirek's flash tool to update the BIOS and unfortunately selected the latest version, which apparently is not compatible. Luckily DNX mode worked and I could use the tool in this thread to flash the correct BIOS. I used the dualboot bios from techtablets. It finished with FPT operation passed, but did not automatically reboot. After manually rebooting, it launched the screen with the options Android and a small Windows logo. I selected Windows and it started the Windows installer from the USB stick and the rest I've described above. If I start my tablet now, the Android and Windows logo are equally large (so it did install a part of Windows?). Unfortunately I haven't checked if DNX mode worked between flashing Dual boot and installing Windows.
I've ordered an USB programmer already

Teclast X80 Pro (E3E6) Dual OS (Win10/Android 5.0): Remove Windows

Hey guys. Sorry to bother you in the X98 section, but since there's no section for the X80 yet and maybe the devices have some similarities, I hope it's ok.
The tablet worked fine, but to remove any possible bloatware under Windows or Android, I reset Windows. Somehow the device must have crashed (low battery?) and now I can't boot to Windows anymore (black screen and / or boot loop). Of course I made no backup / recovery disk. Android still works fine and I still get into BIOS / UEFI.
I tried reinstalling Windows via OTG with USB stick. I got to the point where I can choose a partition. Problem is, there are lots of partitions (Android, recovery, System and so on). I located the Windows partition, formatted / deleted it and tried to reinstall Windows on this partition. Just the exact way I would do it on a PC. Somehow it won't install on this partition. The error message says something about "the partitions are not in the recommended order. Further information for installation on GPT-volumes..." (I don't know the exact English phrasing because everything is in German). I chose "continue anyway". Then I get the message that "the EFI-system is not formatted in NTFS. Format the partition to FAT32 and start install procedure again". I press ok and get back to Windows Setup (Install now).
I also tried different repair and recovery options. One time I got error code 0xC0000034. Funny thing is, Windows still seems to be there because while trying to repair / recover I tried to load some drivers and could see the hard drives and folders under Windows.
I tried downloading the original roms here: http://pan.baidu.com/s/1qYEa8gc
You need a Baidu account for the larger files and after days and days I gave up to create such an account as it seems to work only with a mainland China number. There's an option for oversea mobiles but that's not working. I tried a QQ-account, but Baidu wants to link with it and you need that telephone number again. So apparently there's no way to get the original files that way.
I found some stuff here: http://www.needrom.com/download/teclast-x80-pro-dualboot/ but that's only a tutorial file in Chinese and some flash programms / drivers (also got them from Baidu - smaller files are possible to download without an account).
Long story short: I guess recovering Windows 10 is too much effort, so I want to make the tablet Android only and of course want to use the whole capacity for Android. I found a thread on reddit about removing Windows on the X98: https://www.reddit.com/r/teclast/comments/479eua/teclast_x89_how_to_remove_windows_10/
But I have no idea which partitions are definitely needed for Android and which ones I can safely delete. I found a partition map here: http://wheresmykeyboard.com/2015/08/teclast-x98-air-64gb-dual-boot-default-partition-map/ but that doesn't help me that much because they look different.
Attached you will find a photo of all the partitions on my device. I guess there are some which were created during the failed Windows installation because I had about 20 GB free space and now only 17.7 GB.
So is there anybody out there who knows if it's possible to remove Windows completely and which partitions I have to delete?
Did you ever figure this out? I just bought an X80 Pro and was thinking of doing something similar since I plan on making it an android-only tablet.

Hi. Sorry for the late replay. Yes, I figured it out and my X80 Pro is now running Android-only with 32 GB. In the end, it wasn't that hard but a long way to success.

Yes please tell us how metalaxi , it'll be much appreciated.:good:
Ok, guys. Since some of you are asking how I did it, I'm going to try to explain it. It's kinda embarrassing that I don't remember the exact way but I hope it helps somehow. I used the tutorial from this site: http://techtablets.com/forum/topic/x80-plus-android-os-only/#login
Even though it's supposed to be for the Plus model, it also worked on the Pro. Btw, the guy Alex in that thread is me .
You can download all the files from my Google Drive here: https://drive.google.com/open?id=0BxEFqy4Rt9w_cnh3VG9ySk5sOHM
You need
- Android5.1 Upgrade Tool.rar
- X80 Pro (E3E6)- Dual OS - Android5.1-V1.04 Firmware.rar
- gpt.rar (Credit goes to Allember @techtablets-forum; hope it's ok to spread the file)
First you have to install the flash tool. Unrar the firmware and replace the gpt.bin. Then flash the firmware by checking BLANK.
Problem is that when I did all that, my Windows was already crushed and wasn't working anymore. I can't remember anymore if I erased the Windows partitions or any others beforehand. If you're not interested in Windows anymore, just flash it without changing or erasing any of the partitions. I guess by replacing the gpt-file, you do all that automatically.
I hope this somehow helps you. Feel free to ask for more help.
Have a good night!

Hi @metalaxi. Do you think its possible to like "reverse" and use the same files to remove Android instead and maintain the Windows 10? Appreciate to hear from you. Thanks!
Do we have to change the gpt before doing what you said in your PDF? Or I have just to follow your PDF?
Hi guys, got mine a few months and want to get rid of the Windows part, but the instructions are insufficient for a joker like me.....
1. Download the firmware, its 4 parts of rar being zipped together
2. flash the firmware HOW?!?!?! I have no Idea...... please give us some closer instructions.

Sorry, I can't answer that sufficent enough. As far as I know, you can just delete all partitions except the ones from Windows. Then format the unallocated space and merge it with the one from Windows. No guarantee!

1. Which 4 parts do you mean?
2. To flash any firmware, you need to install all the upgrade tools:
IntelAndroidDrvSetup1.5.0
iSocUSB-Driver-Setup-1.2.0
PhoneFlashTool_5.3.4.0_internal_win32

it's too long ago, so I don't know what I exactly did there, but since there was no reply for a long time, I just took a shot and worked out well, now I have an Android only tablet.
I just got lucky I guess....

Please help. I can not download from Baidu
* If I use phoneFlasTool and flash a blank disc - Create Flash partition and dual boot and replace recovery?
What to do with an empty disc?
Thanks for any advice
It is not so hard. By mine it was only trial and error. Installiert all drivers an go in the bootloader with three Finger method. Go two levels up and go into bootloader. Then connect to PC and look in Intel flashing tool if connection is reconiced correctly. Select the downloaded file and select flash. Thats it. Device will reboot and you are ready to go.

Thank you for the advice. That's right, I did it was marked. I found a reason. rom file was saved on desktop, and had a long name (as I downloaded it) It must copy the file to C've renamed the firmware. Everything went alright. I downloaded and used the GPT files for resizing disk and now goes all right. Thank you for responding to my question.

Straightforward if you can obtain a USB stick capable of storing over 7GB (some 8GB sticks may not); USB hub (ideally a powered hub); USB keyboard; OTG cable.
1) Obtain the Windows files of the correct firmware. The procedure outlined here is for E6E9 firmware, but other firmware will be similar. Download the circa 6.5GB E6E9 firmware Windows files from https://yadi.sk/d/XEvRsoiD3Q4vKX or https://mega.nz/#F!I0AXGR5C!YiNFkZL9DIvzepH28qAjEQ (or from appropriate source for your firmware version).
Decompress the downloads as required to obtain six folders and two files.
2) Format the stick to FAT32.
3) Name the stick WINPE (five uppercase characters).
4) Copy the previously mentioned folders and files to the USB stick.
5) Plug USB stick and USB keyboard into hub; plug hub into OTG cable; plug OTG cable into tablet whilst the tablet is off.
6) Turn on tablet and immediately start tapping << Delete >> key on USB keyboard. This should open the UEFI config section prior to Android boot option. If the tablet displays the Android boot option, turn off the tablet, wait a few seconds, then turn on and start tapping << Delete >> key on USB keyboard again.
7) When in UEFI, touch the title menu option of << Save and Exit >> and look in the << Boot Override >> section for the name of your USB stick, then touch the name of your USB stick. The screen will immediately go blank as the tablet starts to boot from the USB stick.
8) After a few minutes, a numerically display of progress will be displayed in a CMD window.
9) After reaching 100% and nearing completion of the overall installation, the tablet will prompt for acceptance, so accept that prompt.
10) The setup will run a few final operations for a few seconds, then automatically reboot.
11) Done.
You will be prompted to complete the OOBE on each Windows boot until you complete OOBE.

Question Partially bricked phone

Good evening.
I have the following equipment and an unsolvable problem:
- Oneplus Nord CE 5G
- Twrp-3.5.2_11-ebba
- Bootloader unlocked
- ADB platform tools 30.0.5, 33.0.1 and 33.0.3
For the last five months I have been trying to root the phone but nothing works. The only thing I can start is twrp in recovery mode.
System boot generates: dm-verify device corrupted Force Dump kernel_restart.
Initially, internal and OTG USB showed 0MB but I could change the file internal file system and now it is showing the correct capacity. The laptop also detects it now as internal folder but no contents.
OTG USB never shows anything and I have tried different SUB sticks and formats.
There is no way to transfer anything from the PC to the phone or vice versa.
When in twrp recovery mode, the phone accepts ADB commands but whenever I try bootloader mode or fastboot mode from the twrp menu, I cannot issue fastboot commands from my laptop (which worked before when I unlocked the bootloader).
I believe the only way is to flash the phone completely and I have extracted the files using Payloader Dump.
However, without fastboot commands there is no way to transfer anything to the phone and install.
I have not tried an SD card yet and it would be a nano type.
Does anyone have any idea? I am seriously frustrated and have seen any error message imaginable.
Thanks a lot in advance.

While your phone is in fastboot and connected to your laptop; How is it shown in device manager?
Good evening.
I found the solution to unbrick my Oneplus Nord CE 5G and here it is.
Status: - normal start leading to Qualcomm Crash Dump screen
- Recovery mode into TWRP possible but no transfer of files to/from phone
- No Fastboot possible
Procedure:
Install Qualcomm USB Drivers from
https://www.getdroidtips.com/download-qualcomm-qdloader-hs-usb-driver/
You may have to launch the command prompt as admin and type:
bcdedit /set testsigning on
I did not have to do it because the Qualcomm Driver installation did it for me.
After restart you will see the following message in the lower right side of your PC:
Testmode Windows 10 Pro + build number
To get rid of end at the very end type:
bcdedit -set testsigning off
Download the following package:
Europe: https://onepluscommunityserver.com/...BA/R/OnePlus_Nord_CE_EU_OxygenOS_11.0.9.9.zip
India:
https://onepluscommunityserver.com/...R/OnePlus_Nord_CE_India_OxygenOS_11.0.4.4.zip
These packages contain the MSM Download Tool and the respective files. Beware that you have to get the correct bundle for your phone. Other bundles contain MSM Download Tool too but will not be compatible and the tool generates a failure message.
Launch MSM and type OTHER at login.
Target was EU in my case.
Then click on start.
Now your phone needs to boot into EDL mode. It worked for me from the TWRP Reboot screen but supposedly starting the phone by holding the volume up and down buttons for 45 seconds does the same.
The screen will be totally black, no beep, no vibration, no feedback.
Then connect the USB cable and MSM will start working. After about 5 minutes the phone should be back to normal.
ADB commands worked again too (phone was being recognized as USB device under device manager). However, fastboot did not work. The device was listed as other device in the manager.
After updating the driver using the following files everything worked:
https://drive.google.com/drive/folders/1D96njoYn-n3alu3ggaK3Kw8hMGLKhJVg
Now I am back to rooting and will report about that too.
Good luck
