UPDATE (26.01.2016):
Normal Boot:
It is not booting more than stock logo
Recovery:
boots into TWRP but cannot mount partitions or format them
Fastboot
Connects to flashboot, says it flashed system ok, but not flashed system ok (nothing changes)
Connects to flashboot, says it flashed recovery ok, but not flashed recovery ok (still TWRP)
fastboot erase system, recovery, other partitions, gives an error
SP Flash Tools
DL/Checksum Checkbox Checked, Download goes all the way to 100%, CHECKSUM ERROR, Still not working.
Below recovery.log - log from breaking-up-the-device process up to now
new1.txt - partitions when the device was working correctly
ORIGINAL POST:
Hello.
I started with changing stock TWRP with CWM then proceeded to change stock Vibe UI with Cyanogenmod (from needrom). First Update 2 version then Update 3. The phone was unstable, loosing settings logging out of applications etc.
Decided to change to MIUI (this one)
But first decided to change back to TWRP (this one)
After Partition Format i tried to install MIUI but it failed.
Then i tried this guide: https://www.youtube.com/watch?v=TySRc_DkcFk
All files i downloaded from the links in the guide.
SP flash tool flashed to 100% and then gave me the message BROM ERROR : S_CHKSUM_ERROR (1041)
(I did select "All versions" File)
TWRP Log started giving me E: unable to mount /data (/system /storage and everyting else at once)
Cannot mount partitions manually either
tried fastboot flash recovery to CWM, it says OK but there is still TWRP.
tried flashing recovery through TWRP install - says cannot mount /data
Phone is not in bootloop but stuck on Lenovo logo.
Is this internal storage failure? Can i check or restore stock partitions somehow? Is this maybe TWRP not seeing partitions?
And why i cannot flash partitions through fastboot?
I would appreciate any, even slight help. Thanks.

hi
i am sharing my experience.
i too changed recoveries frequently & not able to mount sd card in recovery,currently i install files needed to be flashed to the internel memory & flash them from there.
i would suggest reinstalling the stock rom first,then install recovery of your choice, copy rom file to the internel memory & then flash it.

Can i ask you how you do this?
I tried putting img or rom on sd card and flash it from recovery but it said "E: cannot mount /data"

you need to download stock rom which is flashable thru sp tools from the hackerpowers index thread,use sp flash tools to flash stock rom. since sd card is not mounting it is better you go for this option. i think once your phone boots up sd card might not be detected by the phone, anyway all the best.

Thanks. I did try with RootJunky's one: http://rootjunkysdl.com/?device=Lenovo K3 Note&folder=Firmware
But unfortuneatly got error:
BROM ERROR : S_CHKSUM_ERROR (1041)
and it's not working
(btw, It's not checksum as it first flashes to 100% then displays the error)
Yet I haven't tried with those. I will.

Did you manage to get your phone out of boot loop

Unfortuneatly not. Here's update:
1. v3 version of SPflash dont want to flash had to stick with v5
2. after flashing official rom (K50_a40_S112_150610_row) phone is stuck on Lenovo screen (no bootloop though)
It stayed like that for an hour before i started to do anything else.
fastboot erase <partition> does not work. Gives an error.
i've managed to do a log dump from TWRP - in attachment
Iv'e also noticed that i have a TWRP full backup before i started doing anything, the problem is, I cannot get it on Storage as dthe /data and /system partitions are corrupted.
Is there any way i can restore TWRP backup f.e. through fastboot or SPF tools ?
Is there any way to just Repartition the whole EMMC_USER?
could i dump whole EMMC_USER from other K3 note and somehow flash it onto this one?
EDIT: Also Found Partition logs from the beggining log file (new1.txt)

as it says this is the one to flash through SP Flash Tools.
Now i Have SP Flash Tools v5
Download Agent: MTK_AllInOne_DA
Scatter loading file: The file from the archive
Download Only (Actually i tried both - no luck)
I hit Download, then connect the Phone.
The download Starts, Flashes to 100%, then gives BROM ERROR : S_CHKSUM_ERROR (1041)
After restarting the device it goes forever on the loading logo.

In the flash tool have you checked DA/DL under options. I have flashed many times without any problems.

I did, also different drivers - no change
UPDATE:
I managed to get ahold of second K3 Note.
I did FULL memory reas using SP flash tools and FULL memory write on old device.
The problem is - write restarts at aprox 27%
Yet, recovery still stayed TWRP.
I belive i did not unchecked "update cm recovery" under CM12 and noe it keeps flashing back.
Anyway, I still think it's a hardware problem right now.
Thanks for the help guys

Hi Gogolian
did ou solved the problem with the K3 note?
I have exactly the same problem, all exactly the same, and everything I try fails.
It would be very hlepfull if you can comment how did you managed finally
Thanks in advance!

Same problem here, believe the memory (emmc ?) is damaged somehow and needs to be reformatted.

fastboot flash bootloader. Are you trying to flash N Preview?

my device was running fine with 5.1 and not sure what caused to get into this stuck where its stuck in fastboot boot
i am just trying to flash factory images from https://developers.google.com/android/nexus/images#shamu

Given the suddenness of your problem as well as the symptoms, I believe the internal memory has failed, meaning a service call. However, I hope I'm wrong.
Regardless, flashing factory images won't work because your bootloader is locked. Assuming this is a software issue you may be able to restore the system by sideloading the Android N OTA through recovery. If you can successfully do that, head to Developer Options in the N preview and enable OEM unlock. From there, unlock the bootloader, so you can flash factory images.

- I read some threads on sideload, they need device booted with adb access, since mine is stuck in fastboot, i don't have access to device via adb, would side load still work?
- still looking for zip for side load for nexus 6, if you have pointer for it, please let me know

To sideload the Android N OTA, which is the only thing that will help you here, you need to be able to get into recovery and set the recovery to adb sideload mode. If you cannot get into recovery, you definitely have a hardware problem and will need to get the internal storage chip replaced. As for the Android N OTA zip, check in the General subforum. Of course you could also simply do a quick Google search for "Android N OTA Brick" and get to Google's page of OTA zips that way.

Android N has a new bootloader, so sideloading it will probably make the device not boot into Android.
---------- Post added at 08:24 PM ---------- Previous post was at 08:23 PM ----------
Have you tried flashing a TWRP recovery and maybe flashing a custom ROM to see if it is a storage issue? This phone is not even two years old, it should not be having internal storage issues.

The Android N OTA I'm talking about includes the bootloader, as it is a full system image. Flashing TWRP will not work as the device has a locked bootloader. But since the device apparently has no partitions at all, the exercise I believe is moot. This is a hardware issue.

Run 'fastboot format cache' and 'fastboot format userdata', then run the most holy words in android 'fastboot oem unlock'. Check this: http://forum.xda-developers.com/nexus-6/help/solution-stuck-bootloop-locked-t3053783 it really helped me out of a deep hole.

The only way that will work is if the OP enabled OEM Unlocking in Developer Options prior to the device forgetting its partitions. I hope he did, as having the option enabled doesn't affect the ability to get OTAs from Google. If however his device's EMMC chip failed as I believe, it won't help him resolve this issue.

If it's failing to initialize the partition table, there's nothing you can do here. It needs to go to Motorola for warranty service.
EDIT: How I can tell? The date was set to 1/1/70. That's the beginning date of the Unix clock, which means something got screwed up internally. That plus the lost IMEI and the failure of the device to find its partitions means a bad device.
Sorry to be the bearer of bad news here, but this isn't something software can fix.

Thanks for looking in, warranty must be void since i had open the back cover .

Not a worry. I know a lot of people advise it but we don't condone it. This is why the disclosure in the OP of every rom thread. We accept what we do might mean killing our device and having to buy a new one. It's a risk of the hobby.

BLU R1 HD Boot Loop after OTA

Hello,
I have an Amazon BLU R1 HD which I flashed with a standard OEM ROM based on the instructions in this forum, its been working great for months until I stupidly accepted an OTA (this one)

Since the update the device is stuck in a boot loop. I no longer have adb access to it (adb devices shows nothing) and I've tried to unlock the bootloader using SP Flash Tool and method 2 from here https://forum.xda-developers.com/r1-hd/development/r1-hd-amazon-bootloader-unlock-method-t3426104 but I just get a s_brom_download_da_fail error. I've tried on Windows and Linux, same results.
Can anything be done? Does anyone have any thoughts on this?
Thanks!

Since you had converted to OEM version. You most likely already had unlocked bootloader. Also when you take an ota with unlocked bootloader you end up with half re-locked bootloader and a boot loop.
We have already seen this in the forum , and have an easy solution.
But to verify the situation before making changes do this:
Hold volume up while phone is boot looping. it should eventually go to the boot menu. Select fastboot. Connect to your pc.
Open cmd window. type this "fastboot devices" you should get almost instant response. " *your serial number* fastboot"
now that you verified you have the connection type this "fastboot getvar all" the response is a list of partitions then near the end there is the bootloader status
"unlocked = yes"
and
"secure = yes"
if this is true then my assumption is correct. It should be "secure = no" for an unlocked phone.
Now type "fastboot oem unlock" followed by volume up button on phone.
follow that with "fastboot format userdata"
obviously this will factory reset your phone.

Since you had converted to OEM version. You most likely already had unlocked bootloader. Also when you take an ota with unlocked bootloader you end up with half re-locked bootloader and a boot loop.
We have already seen this in the forum , and have an easy solution.

Thank you, your assumption was correct and that has fixed the problem. Obviously my search foo failed me.
I appreciate the quick reply and assistance.

Don't have any proven information to give you in your situation. All previous boot loops after taking an OTA have been a result of already having bootloader unlocked.
I would normally suggest trying to do a factory reset in a boot loop situation . So if you can get into recovery mode try to do a reset. If you cannot get into recovery you can try to do a "fastboot format userdata" and / or. "fastboot format cache"

Thanks for your suggestion. Unfortunately, Recovery mode doesn't seem to work. I did Factory reset , and then reboot, it stays on white BLU screen.
Additional Info: I did a ROOT INTEGRITY CHECK. It fails stating several files modified. I am not sure if that is an indication of any problems.
So I fastboot'ed again and tried format userdata and cache.
Both result in Failure - Not Allowed.

You are not allowed to format from fastboot because , not bootloader unlocked. So not unlocked, no custom recovery, and integrity check says system files are changed.
It is most likely end of line for that device. Only option I can think of is factory repair. Phone must be less than 1 year old. (released July 2016) They have 12 month warranty I believe.

I have the Amazon R1 HD and I too fell victim to the update install that relocked my phone so its stuck in the reboot format. My problem seems to be when attaching my phone to the computer as instructed previously to another Blu...after typing in "fastboot devices" I receive an error code stating the Android device has no drive. I am almost past exasperated. Help, please!

Please help
I tried the spitting flash tool method to get my phone out of bootloop it won't work because I can't turn it off. It's battery has to die out then when I plug it. It automatically goes to the BLU screen and stays there for a bit then powers off and turns on again. I tried plugging it in to my pc and using fastboot devices but I get this error.
'Fastboot' is not recognized as an internal or external command operable program or batch file
And I can't power it off to begin the flash every time I get a timeout and I have all the mtk drivers install and the MT65xx USB vcom drivers I'm so confused I have a week working on this issue

You are throwing a lot of different things together, but sounds like none of the steps are right.
If you have been stuck in a boot loop after an OTA update (like title of thread you are in) , and your phone was bootloader unlocked before taking the OTA update, then the following information should help.
If you are in a boot loop for other reason then this will not help.
While the phone in Turing on / off, hold volume up. Eventually it should come to the boot select screen. Use volume button to scroll to fastboot and power button to select.
Now plug usb into pc and open CMD window. Verify you have the fastboot program on pc, and it sees phone by typing "fastboot devices"
Your statement said you got response that fastboot was not recognized command. I suspect you may not have fastboot on pc, but it no fastboot on pc how did you unlock bootloader?
Moving on., Once you have fastboot recognizing the phone , type "fastboot oem unlock"
Should be message on phone screen asking to confirm by pushing volume up.
Next , if phone has stock recovery you can just reboot and stock recovery will wipe /data and phone should reboot.
If phone has custom recovery (twrp) need to format userdata and cache. Type "fastboot format userdata" then "fastboot format cache"
And again I must state that if phone is boot looping for other reasons then this may not help.

Can't Get USB Debugging / ADB to work WiN 7 32bit

Hi All not to sure what is going on but i'll try to explain as much as best as i can hopefully someone help i can get my phone to show up with usb debugging enabled windows device manager just shows it as R1 HD with a yellow " ! " forcing it to install as ADB interface does do much it installs but does not show in adb with "adb devices" phone has debugging turned on and ive installed android aio driver pack from androidmtk.com didn't help though im at a loss my computer recognizes the phone in mtp or ptp if i turn off usb debugging but like i said just shows up as R1 HD with an exclamation mark either way in device manager so im guessing its driver related but i can't find the right driver so i really would be grateful to get some help.
phone version : BLU_R0011UU_V17_GENERIC 15-11-2016 14:41
Build Number: MRA58K

Are you running Windows 7 or 10, 32 bits or 64 bits ? running MTK's usb drivers ? using the OEM Blu usb cable ? tried a different usb port ? Is your Settings > Security > Unknown Sources enabled or disabled - toggle it and reconnect, any difference ?
Check for possible usb drivers conflict, uninstall those & reboot and then try a fresh install, on a different port, with a different PS and/or OS, or a Linux machine (gotta loved my old Dell Laptop D410 with new life, as good as a Chromebook.) Look under Device Manager & check for hidden/unknown devices.

Hmmm, is your bootloader locked or somehow got relocked after an OTA update/flash ?? How long have you owned this - rooted or not, rolled back the firmware ??
Do a manual reboot into bootloader (without using ADB) and post what those values are - especially about firmware, bootloader & unlock status ? pre-loader version ?
Backup any settings & important files on your R1 HD first, pull out any storage mSD card, do a factory reset - and - if you are sure that it is not bootloader LOCKED - download & run one of the dirty-cow-batch file (don't use the newest one as it didn't work on my other R1 HD now on the modified non-Prime version, was getting an error message when I tried to unlock & root it - one of the older one with the Linux option is what I used)
I then installed TWRP, flashed the modified factory rom, ran the debloat batch file also and flashed the latest SuperUser for good measure along with Busybox.

OK, from the last few lines - it indicated your device has an unlockable preloader/bootloader (yet to be done) and once it is, you can root it and install TWRP, and flash the "modified" stock ROM, i.e V2.85
See this thread/post - read the first page & last few pages about some of the discussion, use V10 of the tool - it worked on mine, and if it doesn't - try V8 also.
Make sure you installed & have working ADB and the MTK usb drivers (uninstall & reinstall)
https://forum.xda-developers.com/r1-hd/how-to/unlock-tool-t3561333
See this about running the batch file.
https://forum.xda-developers.com/r1-hd/how-to/blu-r1-hd-v6-6-dirtycowed-f-amazon-root-t3490882
Make a note of any error messages on screen. Have fun.

I got a HTC phone from a friend and I do not know how to find out the model. Also it does not have an OS on it and I am looking to find out how to install one. I read a few of the threads and could not figure out what the terms meant. Such as OTG, RUU,ADB, TWRP, ETC. So I am not able to follow. Please assist me if you can.

You say it doesn't have an OS on it, so it's basically a blank device that you need to install an OS on.
Th easiest way for us to identify it would be for you to take a photo of it and post it here for us to look at. Once we know what model of HTC you have, we can easily help you get Android back on there.
Or if you can find it on the HTC website, that would help. Or even Google somewhere.

I found that it is an HTC One M7.

Ah in that case, take a look in our HTC One M7 forums: https://forum.xda-developers.com/htc-one
In "HTC language", an RUU is a ROM, which is what you need in order to flash the OS back onto your device.
I haven't owned an HTC for a number of years now, so I can't recall the place place to find stock firmware (RUU) files.
I will move this thread to the M7 Q&A forum for you, so that hopefully someone else can assist you further.
It will probably help if you can let us know which region you are from, as firmware is often region specific. Which country?

We"ll need a bit more info to indentify your phone. If you dont already have adb and fastboot installed on your computer, Google search for "minimal adb and fastboot". You should find an xda thread explaining how to set up adb and fastboot. Once done youll also need to install HTC drivers. It can be done by installing HTC Sync manager from htc's website. Then connect your phone using the usb calbe, boot in bootloader mode (power + volume down). Start the minimal adb and fastboot terminal window and type "fastboot getvar all" (without the quotes. Post the output of that command in this thread (take care to remove the imei and serialno lines before posting).

There is a mismatch between your version-main and your cid/mid. The version-main (firmware version) is an old at&t version but your cid/mid are set to accept t-mobile firmware. That will be easy to fix but first what OS do you want on your phone? The latest official Sense rom (lollipop 5.0.2), latest GPE rom (lollipop 5.1) or latest custom rom (Nougat 7.1)?

From what I understand it originally was an AT&T phone that was switched to T-Mobile. As for which OS. I am not picky so whichever is easiest and then I guess the newest.
Thanks again.

Is there a custom recovery installed on your phone, like TWRP or CWM?
Boot your phone in bootloader mode then select "recovery" and hit the power button. If you don't see "recovery'' that's because you"re booted in "fastboot" menu, in this case select "bootloader" and you should see the "recovery" option.
Your phone will reboot in recovery mode, just need to know what recovery is installed for now. If your phone is running stock recovery you will see an exclamation mark in a red triangle, otherwise you'll see TWRP splash screen or CWM menu. If booting to TWRP or CWM please report back what version number it is.

Good, we can fix your CID and MID first. You can use this guide to write supercid to your phone. WIth your phone in bootloader mode (in the fastboot menu) Start the minimal adb and fastboot terminal then follow the guide from step 9 - 12.
Then to change your MID reboot in recovery and type:
Code:
adb shell
and
Code:
echo -ne '\x50\x00\x4e\x00\x30\x00\x37\x00\x31\x00\x30\x00\x30\x00\x30\x00\x30' | dd of=/dev/block/mmcblk0p6 bs=1 seek=16384
Better to copy/paste that one...
Then reboot in bootloader mode again and confirm your mid is now PN0710000 (your can use the "fastboot getvar all" command)
Download this firmware and save it in the same location where minimal adb and fastboot.exe is installed on your computer
WIth your phone in bootloader mode (fastboot menu) type (the command is case sensitive btw):
Code:
fastboot oem rebootRUU
Your phone will reboot in RUU mode, you should see a black screen with a silver HTC logo
type:
Code:
fastboot flash zip M7_UL_Firmware_7.19.401.2.zip
Should take a few seconds before saying : FAILED (remote: 90 hboot pre-update! please flush image again immediately).
So do the same command again:
Code:
fastboot flash zip M7_UL_Firmware_7.19.401.2.zip
The second time, it should take a few minutes and you'll see "okay" at the end, then proceed with
Code:
fastboot reboot-bootloader
Back in bootloader mode again, confirm your version-main is now 7.19.401.2 (use "fastboot getvar all")
If everything went fine you can proceed to the final steps:
Download this RUU and this version of htc_fastboot.exe and save both files in the same folder where you already have minimal adb and fastboot.exe.
reboot again in ruu mode:
Code:
fastboot oem rebootRUU
and once there type:
Code:
htc_fastboot flash zip RUU_M7_UL_L50_SENSE60_MR_HTC_Europe_7.19.401.51_Radio_4T.35.3218.16_10.33Q.1718.01L_release_458803_signed.exe
The flash should take a while and your phone will reboot once during the process. Once 100% done you can reboot the phone and it will boot in the OS (android 5.0.2 with HTC Sense)

The first step changing the CID worked. But when I tried to change the MID I had a problem. When you say boot into recovery do you mean go into recovery from the hdboot screen? The only way adb can find the phone is from the fastboot screen. here is what I get when in recovery :
adb shell
adb server is out of date. killing...
ADB server didn't ACK
* failed to start daemon *
And when in Fastboot:
adb shell
adb server is out of date. killing...
* daemon started successfully *
error: device '(null)' not found
Also, When I boot into fastboot the phone is identified as Android in devices and the HTC Sync Manager finds it. In hdboot or recovery it is identified as "one" and HTC Sync Manager cannot find it.
Sorry for all the difficulties.
Thank you.

try with twrp recovery instead, you can download it from here and as usual, save it in the same folder where you have your minimal adb/fastboot.exe installed
to flash twrp, boot in bootloader mode (fastboot menu)
Code:
fastboot flash recovery twrp-3.2.1-0-m7.img
fastboot erase cache
fastboot reboot-bootloader
then select "recovery" and wait for twrp to boot (you'll see a twrp splash screen, then the twrp main menu. With your phone in twrp main menu, you should be able to use the adb commands.

I cannot figure out where ADB is located. The program I have installed allows me to use it from anywhere. Here is what shows up when I open the powershell. Isn't there a way to open the shell in any folder?
Windows PowerShell

Now with TWRP loaded I get a message about a partition. DoI want to have a parition??
Unmodified system partition
Keep system read only?
TWRP can leave your system partition unmodified to make it easier for you to take official updates. TWRP will be unable to prevent the stock ROM from replacing TWRP and will not offer to root you device.
installing zips or performing adb operations may still modify the system partition.
Now when I run code: "adb shell" this is what shows:
adb server is out of date. killing...
* daemon started successfully *
~ # 
And it just stays there.

That is exactly what you want, you can now type your commands.
