Hi state of pins. For me MCU firmware started. Maybe now there is problem in other place.

PB3 (PWR_ARM) is Hi so on SOM VSYS+5V (pins:1,2,3) should have 4.2V (according to schematic), and SOM should also started
[MTCD  Android Head Units Q&A] Kayhan 17#:
Im shocked!!!

Bought me a RCD210 at 3 o clock, got home and discovered the stupid PINCODE doesnt works, hooked up the Abrites in the hope of being able to haxx the pin, notebook power went low so got in my room.

Thought of, Hey! what about you dont put in the cables loose anymore in to the molex connector ->so i soldered some good wires with molex female connector as ipossibly will flash this device the next two weeks?!

i removed the flex cables...thought of hey look at the screen maybe you can see something changing when playing around with flex cable of the TFT...lit on it with my flashlight and could see some stripes...started to make a video on 1st attempt and WTF? radio started with that yellow sign symbol..

i was like WOW, then the 2nd video attempt because phone fell of my hand on the 1st...radio booted fine as you guys can see :silly: here

now while uploading on youtube i restarted radio (screen got of because of standby and buttons not connected/flexcables) and it smelled a bit cooked xD, however it doesnt boot up now and yellow sign appeared..

Will try right after this posting, because maybe it cooled down while i typed this text?

EDIT: doesnt boot up, the warning symbol comes up now =) maybe i try the first recover.bin?

and the smells maybe because i changed that TDA750... sound chip

EDIT2: flashed first recovery.bin, it booted straigth into system
[MTCD  Android Head Units Q&A] Wadzio:
Long story :)

You probably do too many things at once. I mean soldering TDA sound chip.

Finally: problem solved ? does the unit work or not? Is the firmware recovery.bin useful or not?

BTW: link to video does not work.
[MTCD  Android Head Units Q&A] Kayhan 17#:
Buddy, recovery.bin(1st file) is the better one as it starts android everytime, where the second file only started once by luck and showed that warning like symbol. Check the video, i uploaded it and mistakenly set to private, its unlisted now!

Send me your paypal adress, i want to donate a bit for your effort.
[MTCD  Android Head Units Q&A] Wadzio:
Great. Nice to hear it :)

I did not do it for property benefits. Maybe next time someone help me :)

And remember (probably you know already). This recovery.bin is a simple recovery so you will not able change MCU firmware for other version than KLD_V257. I will try write something more universal, so do not desolder your wires for flashing :)
[MTCD  Android Head Units Q&A] Kayhan 17#:
I offered you, so if you gimme your paypal, i send you a bit of my student money if not its okay too -> i hope i can help you in a different way =)

i could access recovery menu, so i would try to flash newest HA firmware from USB just to find out what happens, because you said it will not work :p(i guess the routines to override with dmcu.img arent there right?)

EDIT: oh and what a coincidence!

The cable-lead in to the Radio was broken, the GND-pin had no contact to the GND-wire so that was also a no-go.

When testing until i discovered it while it didnt work in the car - > after it did fine on the desk ^^
[MTCD  Android Head Units Q&A] marchnz:
Wadzio is a legend!

Developing MCU recovery is incredible work!

Wadzio, with your recovery.bin, would we be able to flash the full MCU manufacturer img code from recovery?
[MTCD  Android Head Units Q&A] Wadzio:
Exactly. It's very simple recovery. Only starts main routines of firmware. This recovery.bin does not have bootloader.

No, reason as above
[MTCD  Android Head Units Q&A] marchnz:
Hi [MENTION=8817431]Wadzio[/MENTION] an [MENTION=1280329]Kayhan 17#[/MENTION],

Can you clear up a question - From the post, Kayhan used a UART-USB converter and connected to MCU RxD and TxD. Wadzio recommended an ST-LINK which is connected to SWDIO, SWCLK - question I have is can either be used or must use UART?

[MENTION=8817431]Wadzio[/MENTION] - what modifications were made to the recovery firmware and how does it work compared to original firmware?
[MTCD  Android Head Units Q&A] Wadzio:
If you have pinpads SWDIO/SWCLK on board you do not even have to solder anything or solder only PinHeader in place designed for that. In [MENTION=1280329]Kayhan 17#[/MENTION] metod you must solder wires directly to MCU pins.

For me STLINK is safetly and recomended by ST.

The only difference between original and recovery firmware is that you can not later update to the new version with standard update procedure. When you want to upload new dmcu.img you will have to reprogram the MCU using STLINK. The rest of functionality will work just like the original.
[MTCD  Android Head Units Q&A] marchnz:
Thanks for the detailed reply. Regarding dmcu.img - could a unmodified dmcu.img be flashed or only your modified version? If you modified, would you mind sharing details of modification?
[MTCD  Android Head Units Q&A] Wadzio:
Maybe this will explain a bit more
[MTCD  Android Head Units Q&A] marchnz:
Nice infographic, thanks. So your recovery firmware jumps over [bootloader] and into dmcu.img code, is that right?

Anyone doing recovery this way must first use your recovery image and then apply dmcu via st-link, do I have that right?

Wonder why the bootloader is protected and also not included with dmcu updates.
[MTCD  Android Head Units Q&A] Wadzio:
Right :)

Each time, when you want new version you must prepare new recovery.bin using mtcdmcutool and apply prepared recovery.bin via st-link.

All manufacturer protect their intellectual knowledge and their work :) (dmcu.img is also encrypted)

[Samsung Galaxy S7 Questions and Answers] mick39:
Hello,

I have a big problem with my Galaxy S7 (SM-930F).

The smartphone reboots and is unstable from the first day.

When it doesn't reboot randomly, I have many application crashes (System apps, Google, Samsung ...)

Here are the main crashes I get :

signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x.....

signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 0x.....

signal 6 (SIGABRT), code -6 (SI_TKILL), fault addr -------- Abort message: 'art/runtime/gc/allocator/rosalloc.cc:1058] Unreachable - page map type:1'

This is also this case in secure mode.

I specify that this is a stock rom and the bootloader was not unlocked.

I sent the phone back to the repair center. They found the problem, changed the battery and updated the firmware. But the problem is still there and I don't what to do anymore now.

Do you have an idea of the problem ?

Thanking you in advance

Hello,

I've bought the Orange SPV M500 a couple of months ago, but I dropped it and now the speaker is not working anymore. A friend of mine has the same one, and he gave it to me. Very happy about that ofcourse.

The strange thing is, when I put my simcard in his M500 it says: missing simcard or invalid.

He called customer service of Orange and the phone is unlocked. But still I get this message with my simcard.

It seems I have a new kind of simcard (UMTS or something). But everyone else can use the phone, even from a different provider.

I would like to use my friends M500...how can I fix this simproblem?

My M500 has operator version 6.06.3.162 and the M500 from my friend 6.12.3.172. Maybe this gives someone a clue?

Thanks in advance!
[JAM, MDA Compact, S100 General] phantom201:
Hi!

I guess this is not the answer you were expecting but if I were you, I'd try to fix your device instead (unless it's broken into pieces).

It's relatively easy to disassemble the device and get the speaker back right.

The chances are that on the impact it became displaced and, since the electrical connections to the speaker are just made by springloaded contacts, if the speaker goes out of place or is pressed hard, the contacs are no longer made and, thus, you have no sound on the speaker.

There is a photographic tutoral made by a member of this forum where that issue is exactly addressed; You might want to take a look at this thread:

http://xdaforums.com/showthread.php?t=234650

If you still want to use your friend's device, then I guess you have to flash a new rom in it and you can find the procedures on the XDA-Wiki:

[One (M8) Q&A, Help & Troubleshooting] xunholyx:
It's a Verizon phone.

I can tell by your MEID (which you should delete by the way ~ the MEID is the same as the IMEI minus the last number).

I did a search using your MEID and it's a Verizon model. For your phone, the last number in you IMEI is "0" :)

The number on the back (0P6B100) is probably because the back cover was replaced when sent for repairs.
[One (M8) Q&A, Help & Troubleshooting] neyoatashi:
thanks for your reply mate ! do you know any way to get my partitions right again ?
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Wrong. Old TWRP version is a big problemo. Not compatible with current ROMs, and serious problems are sure to result.

Also, your firmware is old (as shown by main version 3.28.605.4 which is Kitkat) and therefore is not going to be compatible with current ROMs, either. You need to update your firmware (and TWRP version).

Also, you have the Verizon version M8. That versions uses a different kernel for most other M8 versions. So you should only use ROMs which specifically support the Verizon version. Otherwise, that is another reason a ROM won't boot.

My suggestion, would be to re-write all partitions to factory state using RUU. This will hopefully fix any memory corruption issues, as well as update you to the latest firmware.

https://xdaforums.com/verizon-htc-one-m8/general/vzw-m8-master-ruu-firmware-collection-t2946473

Then go from there to get 3G working, flash latest TWRP (3.1 or 3.2 just came out a few days ago). etc.

You can't go by what is on the back cover. We've frequently seen the back covers swapped, US versions in particular, to remove the carrier logos. In this case, the back cover was swapped to remove the Verizon logo.

---------- Post added at 01:26 PM ---------- Previous post was at 01:18 PM ----------

This isn't strictly true, that "the M8 will only work for the same region it was bought". The Verizon version is SIM unlocked out of the box. Even if not, s-off gives SIM unlock. So from there, it's a matter of whether the M8 version supports the proper bands (used by your local carrier) for 3G or not.

What band (or bands) does your carrier use for 3G?

I wouldn't get your hopes up about 4G (LTE). It's proven very difficult (maybe impossible) to get the M8 working in another region on LTE.

But 3G may be possible.

I did get my phone back to working again ! its seems that my mid was 4 zeros longer ! and by knowing how hex and shell commands work i was able to fix it ! then was able to flash twrp 3.1 and flash a vzw sense 7 based on stock verzion costum rom !

now the only problem is that annoying edge !

supported 3g bands in my country are B1 (2100) And B8 (900 GSM)

im trying to unlocking my bands by DFS but thats seems to do nothing actually ! if this wont do nothing i will flash modem bins from older roms !

and thank you for reply mate ♥
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
The Verizon version M8 should support 3G bands 900 and 2100 out of the box. So you shouldn't need to mess with unlocking any bands. Are you sure you have APN properly configured for your carrier? And the SIM works in another device for 3G?

Whatever you do, do

NOT

flash any radios from any M8 version except Verizon. The Verizon version is not compatible with radios from other versions, and doing so will result in a radio brick!
[One (M8) Q&A, Help & Troubleshooting] neyoatashi:
i get the idea from another one who had the same problem here in xda ! he was able to fix it by flashing older modem ! he has a verzion phone and flashed older verizon modem from a kitkat stock rom !

i checked those bands in DFS ! and 900 And 2100 was not checked ! so i checked them and write !

now once in so many tries when i select LTE/GSM/UMTS mode and LTE/WCMDA in Service Mode Hspa Go for a sec then i get disconnected ( Emergency calls only )

Im getting crazy here mate ! Maybe this is the night that my phone meet the wall in a beautiful strike :(
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
It's worthy trying. As long as you stick with Verizon M8 radios, you should be relatively safe, and you can go back and forth to older or current (Marshmallow) radios. So there is minimal risk in trying. Although any radio or firmware flash should be taken seriously. There is always some risk. If for instance, anything goes wrong while writing radio, a permanent radio brick is possible. But again, the risk should be minimal.

But is your present main version due to trying another radio (Kitkat) or firmware? Since the number you show 3.28.605.4 is Kitkat firmware.

Were you ever on Lollipop or Marshmallow firmware (main version 4.xx or 6.xx, respectively)?

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
The main version definitely means something. You just don't understand what it means.

The main version in getvar (also same as OS number on bootloader screen) is your firmware number, which refers to hboot, radio, etc. This is

not

the same as the ROM version; and firmware does not change when you flash a new ROM. You need to update (to Marshmallow) your firmware either by flashing signed (Verizon) firmware or Verizon RUU.

If you are flashing Marshmallow and Nougat ROMs, using your old Kitkat firmware; that may be the cause of your radio/band support issues. You need to update your firmware.

Hi guys what was your best battery life rom+kernel combination ?

[Nexus 5 Q&A, Help & Troubleshooting] Bigority:
WARNING: DON'T COME TO ME COMPLAINING THAT YOU BRICKED YOUR DEVICE. YOU DO THIS AT YOUR OWN RISK AND ACKNOWLEDGE THE WARNINGS

Here's the best set up I've found, LineageOS 14.1 Nightly, Franco Kernel rk113 3.4.0, SuperSU v2.82, and No Frills CPU Controller. Franco Kernel increases battery life crazily on it's own, then add LineageOS and SuperSU and use No Frills to underclock it. It lasts forever. You could even add the LG G2 battery mod to this and have a god tier battery.

Note though, flash LineageOS > SuperSU > Franco Kernel. If you flash the kernel before LineageOS it may be over written and your kernel will be messed up. (I know this for a fact will happen with Magisk 15.2). Before doing any of this make sure you have a back up using TWRP and/or Titanium Backup in case you mess up.

LineageOS 14.1 Nightly:https://download.lineageos.org/hammerhead

Franco Kernel: https://kernels.franco-lnx.net/Nexus5/7.1.1/anyKernel/ (scroll all the way down until you see a file called "fk-r113-anykernel2.zip" and download that.)

[Google Pixel 2 XL Accessories] JimSmith94:
Why do you say that it's designed to be worn on the right hip? Doesn't the belt clip swivel? I am happy with my Seidio Surface case and holster that I wear horizontally on my right hip, but the bottom of the case is too thick to work on my Seidio desk dock. The low profile of this one might let it work, but I want to be sure I can wear it the same way.
[Google Pixel 2 XL Accessories] Cowbell_Guy:
It swivels, but only 180 degrees. Not a full 360 degrees like some that I've had in the past. I had to be Sido surface case as well, and while it fit on my right hip fine, I can't remember if it's span the full 180 or 360.

Regardless, if you like the phone on your right hip, this will be a great case for you. I've tried about 5 different ones so far and while this one isn't perfect, it's the best I've found. It's very smooth and low profile. It doesn't feel quite as nice in your hand as some of the others, but I think that maybe with some wear and tear over time it will be a little bit easier to grip.
[Google Pixel 2 XL Accessories] JimSmith94:
Thanks for the information. I had assumed my Seidio holster rotated a full 360, but I just checked and it only rotates 180 degrees too. I don't see why it can't be used on the left side though. It will swivel from horizontal right, to vertical, to horizontal left. It can't rotate to upside down, but I don't think anyone would carry it that way anyway.

As long as it is thinner than my Seidio case, I'll try it out and hope it works in my Seidio dock. I don't have Amazon Prime so I'll see if it qualifies for Free Shipping Friday or find something else to get over the $25 minimum.
