Hello,

do not

This phone came with an error in which when turning on it showed a blue screen where it said update, then it failed and it was on screen:

E:[libfs_mgr]
E:[PDP] lstat /c____/pdp_b__ : 0 - No PDP scenario

and entered the recovery stock. where it said it couldn't mount / cache

if I put wipe cache it threw other errors and it was not corrected.

If I chose to start from the system it would be in a loop.

Initially it was with BIT 1 I updated it to BIT 8 using odin but the error persisted, I continued with the loop but (from what I search the web nobody solved it)

After a week of testing with different roms. On February 4, immediately took advantage of activating oem and unlocking the bootloader. When rebooting it did not turn on again but I was able to finish unlocking the bootloader and install TWRP 3.5 from physwizz.

When entering TWRP it does not allow multidisabler-samsung-3.1.zip

giving me an error. I could not mount the vendor partition nor any other. What's more, everything accused 0 MB

Using TWRP 3.3 in combination with the Eureka kernel I am able to mount some partitions.

After that I started to read the system logs to explore dmesg and there I realized that what is wrong is the FMP system

Reading the source code of the linux kernel I see that this works using the partition mmcblk0p5 (CPEFS).

Regarding CPEFS, note that in the PIT file it does not declare which file should be written to that partition.

Checking the other partitions I discover broken SEC_EFS.

I made a backup of what I could using tar and another with dd

and I tried to repair it using e2fsck but it was badly damaged

format it with the same original parameters and restore the files you rescue from backups.

Currently if I install an original rom with odin I get the same scenario.

loop and if I started I recovered the error:

E:[PDP] lstat /c____/pdp_b__ : 0 - No PDP scenario

NOTE: Now I am looking for a merge file. I understand what the factory uses. but I only found up to BIT 7 and my phone is in BIT 8.

Thank you

Excuse my english

Thank you, this guide is very good, unfortunately it does not solve my case. Disable_Dm-Verity_ForceEncrypt didn't work either.

The problem of my phone is with FMP = Flash Memory Protector

It fails to start FIPS because a file is probably missing or corrupt. I think that what would help me would be to see the list of files of those partitions to know their name and weight.

It would help me if you can create a text file on your external memory card and paste this content inside:

mkdir /secefs
mount /dev/block/mmcblk0p4 /secefs -o ro
cd /secefs
ls -a -R -l > /external_sd/secefs.lst

mkdir /efs
mount /dev/block/mmcblk0p3 /efs -o ro
cd /efs
ls -a -R -l > /external_sd/efs.lst

mkdir /cpefs
mount /dev/block/mmcblk0p5 /cpefs -o ro
cd /cpefs
ls -a -R -l > /external_sd/cpefs.lst

Or with this other you can make a backup:

dd if=/dev/block/mmcblk0p4 of=/external_sd/secefs.img

dd if=/dev/block/mmcblk0p3 of=/external_sd/efs.img

dd if=/dev/block/mmcblk0p5 of=/external_sd/cpefs.img

(suppose the file is called mkbl.txt)

finally run it from the TWRP terminal:

/external_sd/mkbl.txt

with that I would generate files in /external_sd/

NOTE: If you generate backup files, keep in mind that they contain IMEIs and addresses that are private to you. You could make a copy of the .img file, mount it from linux in a folder and edit the files that contain personal information. Or you can trust me and I can erase that personal information to make the files public.

On the other hand, in the case of the lists with ls, it does not include any personal information, only file names and weights
[Samsung Galaxy A20 Questions & Answers] sercari:
Confirmed cpefs that is mounted in / vendor / cpefs contains only these two files normally.

-rwx------ 1 radio radio 546304 feb 4 20:51 .nv_core.bak
-rwx------ 1 radio radio 32 feb 4 20:51 .nv_core.bak.md5
drwx------ 2 radio radio 4096 ene 1 2019 lost+found

I would only need to find out the content of the partition /dev/mccblk0p4 (sec_efs) which I think is not mounted anywhere when the system is running. for which it is necessary to mount it to be able to list its content. I wait if someone can help me.
[Samsung Galaxy A20 Questions & Answers] sercari:
Finally and mysteriously I boot into twrp allowing me to see all the partitions. (Only TWRP with full memory access would not start the system) Take advantage and I made a copy from partition 1 to 25 to and 31. Unfortunately I discovered that I have the partitions boot0, boot1, boot3, m9kefs, m9kefs2, m9kefs3, nad_fw, nad_refer blank.

UPDATE:

1- Get a copy of m9kefs1, 2 and 3 and I have them ok.
[OnePlus 7T Questions & Answers] Winthryth:
I bought a T-Mobile One Plus 7T HD 1907 off of Amazon. Once I got the phone, I converted to the global OTA, OnePlus7TOxygen_14.O.22_GLO_022_2101280011, I then upgraded to OxygenOS 10.0.16.HD65AA. I never actually used the phone using T-Mobile stock Oxygen OS. The phone number I use with this phone was transferred from Version to Red Pocket's GSMT network. After using the phone for a while, I noticed I was randomly dropping text messages. Someone would send their message, their phone would say it was sent, but I never received it. This happened with multiple people on multiple networks, both SMS an MMS. There does not appear to be any pattern in the messages I miss. I could be in the middle of a text conversation, and the message would just get dropped.

I tried resetting various network settings, changing APN settings, and changed messaging apps to Oxygen OS’s default one, but I still randomly drop text messages. Phone calls appears to be unaffected. I ported my number to Red Pockets GSMA network and the problems still occurs. I noticed the 4G LTE was kind of weak in my area, so I switched my phone to use 3G, which has good signal, but the problem still occurs.

Is there any reason to think the dropped text messages are caused by running the Global OTA on my T-Mobile HD 1907 phone? Or does canyon have any ideas what could be causing this problem?
[OnePlus 7T Questions & Answers] wfred:
Normally if it is a problem with the OS you don't get messages at all, not an intermittent loss.

Are the lost messages coming from people on the same or different networks? Can you swap sim cards with someone on another carrier and see if you or the other person has the issue?

If it is an OS issue you could try reinstalling as a local update.
[OnePlus 7T Questions & Answers] Winthryth:
I have confirmed it happens with people from verizon and t-mobile. The person who is helping me text is on verzion. I don't have someone to swap sim cards with, but this has problem has occurred while I was on Mint Mobile, Red Pocket GSMT and Red Pocket GSMA.

I also have a new point of evidence. The person on verzion sent me an sms and mms message. I missed it. They sent another set 3 minutes later, I missed them. I texted them a message. They then resent there sms and mms message after they received mine and I got their messages.

Therefore, it seems if I text them first, I have no trouble getting replies, but after an unspecified amount of time, I no longer get there messages.
[OnePlus 7T Questions & Answers] nagi_007pk:
I am not in the US and have been using my T-Mobile 7T for a couple of weeks and had a similar problem of not receiving text messages or MMS which I figured could be because of changing my rom to the global version.

I switched back over to the T-Mobile rom and went into the network settings and unlocked it after requesting T-Mobile from an option that's visible there. After doing that I went back to the global firmware and it's been a week. So far so good.
[OnePlus 7T Questions & Answers] Winthryth:
Thanks for the reply. I will try to flash back to the T-mobile ROM once I get the chance. Could you please clarify what exactly you mean by "unlocked it after requesting T-Mobile from an option that's visible there". Does "requesting T-mobile" mean you contacted T-mobile to unlock it?
[OnePlus 7T Questions & Answers] nagi_007pk:
Go under Network settings and scroll to the bottom. It will say tap here to request an unlock. Press on it and it will ask T-Mobile for an unlock. Make sure your internet is connected and after that it will Device is factory unlocked.

Hello all, my first post in the OP8 community. I have a Verizon OP8 and I'm not able to unlock the bootloader. ADB seems to work fine and my device is recognized in fastboot. It gives me this error:

...
FAILED (remote: Flashing Unlock is not allowed
)
finished. total time: 0.002s

I've tried googling for answers, but everything is years old and seems irrelevant or just doesn't work.

I'm not sure if this helps, but "fastboot oem device-info" returns:

...

Hi

Tried comparing the S21 Exynos 4G performance against the S20+ or S10+? It's dissappointing...

I think most users are hitting their home or work WiFi and haven't yet noticed this issue with the S21 Exynos 4G.

If you have these phones and can do a comparison, I would be very interested to see if you duplicate the same poor 4G S21 problems: latency higher, download not as good and upload pathetic with the S21 Exynos series.

See my original thread here:

4G Performance on Exynos S21 Ultra is waaayyy slower than an S10+ or S20+

Hi Has anybody else noticed that the S21 Ultra doesn't seem to deliver consistent and reliable 4G speeds, particularly in terms of 4G uploading. I've done a comparison between my S21 Ultra and a S10+ both on the same network (EE) and the results are shocking. The S21 Ultra simply doesn't...

The problem is exaggerated when you have only an average signal strength. The modem is much more sensitive on the S21 and does not provide a good real world experience.

Same problem here. Any solution ? Thnx
[Samsung Galaxy S21 Ultra] Ipse_Tase:
I'm getting the same performance on the Ultra as I am on the Mate 20 pro...both on LTE and 4G.

Which means that the bottleneck in my case is the carrier.

Somewhat related : I ended up forcing band 12 with less bandwidth but better signal in my area..the phone stubbornly picks band 4 for almost double the bandwidth but 10-12dBm lower signal.

My battery is thanking me. The speed isn't everything.
[Samsung Galaxy S21 Ultra] Elhombree:
I have the issue where i have very poor signal although my operator supposedly has very good signal in my area.

Ever since I bought the device in february my signal has been weak. I have aroumd 110-118dbm and speed of aroumd 50-70mb. My wife has an iPhone and same operator as I do and she gets 60-70dbm and at least double the speed. This is crazy, Come on samsung. This is ridicilous.

I hope an modem update will solve it but somehow it wont. We need to make samsung aware of this issue. My battery is kind of lacking because of this issue.

[LG V30 Questions & Answers] j0n0m:
Hello,

recently my wide-angle camera stopped working. I wouldn't care, but the LG camera app crashes because of it.

It is not the module itself, but a chip on the board that broke because of corrosion, therefore it is unrepairable for me.

I would still like to use the LG camera app, because of its manual control options.

Is there a way to disable that module, e.g. modifying the camera API v1 ("CameraService: CameraService::connect call (PID -1 "com.lge.camera", camera ID ) for HAL version 256 and Camera API version 1") to return the main camera when calling for the wide-angle camera id?

I would be thankful for any ideas. If there is a way to flash a modified camera API that would help me very much. I think I can achieve the rest myself.

TL;DR: Is there a way to flash a modified version of the camera API (v1)?
