[Lenovo Vibe P1 Questions & Answers] shindou01:
Have only tried DoTOS and AEX....

Depending on which (android) version you want, here's the following :

AEX 4.6 (Nougat) and DoTOS 1 (Nougat) I'd choose DoTOS for more stability

AEX 5.6 (Oreo) however so far only has RR (Oreo) and AOSIP (Oreo) to compare to, as there are no DoTOS (Oreo) available (yet). but I've been running AEX (Oreo) since AEX 5.5 and it has been a great daily driver so far.

The thing about Custom ROMs are that they're kinda 'moody'... Might work great on one device, might not work for yours, most likely due to what your using your phone for. So the best way to find the most stable one for you would be to try it out yourself... Use one and fiddle with it a bit, and if you feel it's good enough keep it, if not, try another one right away and keep going until you find which one is your best fit. Afterwards, just keep using it for about a week or two and measure the stability for your daily use yourself. If you don't like it, try your second best fit ROM and repeat the process.

Why a week or two and not just a day or two? Most Custom ROMs would only really settle in after a couple of power cycles and after a week or two of daily use, there should be enough load on your phone to really measure the stability for your specific use.

Hi steadfasterX,

I really appreciate your hard work and commitment. Thank you for the tools you created so we can unlock our devices.

Today I succesfully unlocked my H810 (stock MM, ARB=2), here are the steps I took:

1. Unlocked with Salt (also made basic backup; GPT compatibility - H811)

2. Installed TWRP, booted to recovery and flashed the baseband package H810_UsU_baseband_flash-in-twrp.zip

3. While still in TWRP rebooted to recovery.

4. Rebooted to system

After couple of minutes I started installing the rom from this thread - aoscp_h810_usu-4.2-20180421-unofficial.zip

Here are the steps I took:

1. Rebooted in TWRP

2. Installed TWRP flashable N modem - G4_29a_N_modem_UsU.zip

3. Full wipe (FORMAT DATA)

4. Flashed aoscp_h810_usu-4.2-20180421-unofficial.zip

Immediately after the installation started I received the following error message:

E3004: This package is for device: g4,p1,h810; this device is 3▯▯(▯▯.

Updater process ended with ERROR: 7

Error installing zip file '/external_sd/aoscp_h810_usu-4.2-20180421-unofficial.zip

I can confirm that the motherboard is H810, also when rebooted in recovery the phone is recognized by the PC as 헀h and not as the correct phone model.

Am I doing something wrong?
[AT&T LG G4] steadfasterX:
Pls share the SALT log of the unlock process.
[AT&T LG G4] efto:
Sure, here it is:

https://bpaste.net/show/1b84db71a154
[AT&T LG G4] steadfasterX:
Perfect one star for the fact that you saved that!

....and I take 4 stars as you unlocked with the totally outdated SALT 3.6. Current is 3.15!! Billions of fixes since 3.6.. It would have been just one click to update from within SALT... It's written in the OP..

Ok so extract the UsU unlock package.

Then boot in fastboot and flash these two:

fastboot flash laf laf_UsU.img

fastboot flash raw_resources rawres_UsU.img

Boot to TWRP and grab & share the recovery log
[AT&T LG G4] efto:
I did the steps above, here is the file:

Hey, are you sure you have an H810 with MM ARB=2?

I have been trying to find a kdz to upgrade my ATT H810's LP bootloader (10o) to MM without bricking it, but no luck (all are ARB=3)...

Mind sharing part of your backup? (factory, hyp, modem, pmic, rpm, sbl1, sdi, sec & tz)

I believe this should allow me to upgrade the BL without any brick :)

PS: I would have sent this by PM, but it could be useful to other H810 users...
[AT&T LG G4] steadfasterX:
The log has been removed. Pls always use www.bpaste.net and ensure you select a long duration in the drop down.

Then share the link.

Well but I assume everything is working?
[AT&T LG G4] smzubair:
Thanks a lot for all these efforts.

Hi steadfasterX first of all thankx for all these efforts to unlock LGG4 h810 and twrp and rom. I've done all these steps from unlocking to finalisation and take precautionary measures, since a month I was reading your posts regarding bricked devices. But today I did it. Right now my phone is booting as it is taking long to boot. So Thankx again for all these efforts.:o

After waiting 1 hour 30 mins, removed battery. First of all here is SALT log:

https://bpaste.net/show/c6f026e7377a

I installed twrp successfully, than baseband and than nmodem packages. Afterwards "aoscp_h810_usu-4.2-20180421-unofficial.zip" this rom and "open_gapps-arm64-7.1-micro-20180614.zip" this gapp and lastly Magisk 16. Rebooted and rom never started.

Again wipe and format data, installed this baseband"H810_UsU_baseband_flash-in-twrp.zip" and afterwards installed ROM. Restarted and now green screen "Demigod crash handler:Apps FIQ:XPU error!" appears with some details....

What i'm doing wrong?

Edit: GPT compatability h811 (do I need to install h811 rom? if yes than point me to it.)
[AT&T LG G4] steadfasterX:
Well.. the log you shared telling me that you are on v10 so lollipop when unlocking? Is that correct?
[AT&T LG G4] smzubair:
Yes it is correct :angel:

Edit: Here is the Recovery Log

https://bpaste.net/show/76d9d9491115

and dmesg log

https://bpaste.net/show/780d981f8419

Maybe you need em...
[AT&T LG G4] steadfasterX:
Well you said that you have taken your time to read everything properly but the most important requirement before unlocking is to upgrade to marshmallow latest.. That's mentioned very clearly in the unlock OP.

the reason? exactly your errors you have at the moment. So head over to the unlocked read and read the FAQ to find out how to upgrade your bootloader to MM latest

Ensure you do a basic SALT backup before and afterwards and store then both in a safe place!!
[AT&T LG G4] kudlinux:
The first first boot takes forever time. how long should i wait?
[AT&T LG G4] steadfasterX:
if it doesnt boot after 15 min something is wrong

-
[AT&T LG G4] smzubair:
:crying: I admit that i've done many mistakes as i tried so many time to take a backup from SALT but always ended with an error before and after UsU. So right now I've no backup...... In uNlocking op faq #18 you mentioned

( If you lost your backup there is still a way you can proceed: Follow FAQ #20 )

but from where can I download KDZ? If from SALT than it is not downloading. :confused:
[AT&T LG G4] steadfasterX:
do a SALT backup of your current state.

if you have issues taken a backup with SALT write in the SALT thread and post the debug log (advanced menu -> debug log -> upload button)

SALT can not download KDZs.

ah well. the h810 is special in many terms it seems. there is MM available for your model but the file you can find is 21y which has ARB 3 and so would BRICK your device.

the 20n is the first MM version for the h810 and that was delivered through OTA update only (it seems) and I cant find an info about the ARB for that so its maybe not possible to use that anyways. I'll try to find out if we can use that somehow

.
[AT&T LG G4] nagalun:
I have some basic backups (before and after usu)

I could upload a backup if you need it
[AT&T LG G4] kudlinux:
I cannot boot any AOSP in H810. I did flash after USU unlock.

Yes sure and thankx for helping, as right now I've a paper weight slab.:good:

---------- Post added at 08:29 PM ---------- Previous post was at 08:20 PM ----------

I'm just asking as i've another g4 h810 but its power IC is not working so right now it is dead. If I replaced the power IC of my UsU'd set to that one, will it works? As I searched in the market but here in our area LGG4's are rare and no one have its parts. So this option came in my mind. Any other suggestion is welcome as I need one set in working condition. Thankx in advance.:angel:
[AT&T LG G4] steadfasterX:
Sharing those would be great. Just leave out these files:

misc, modemst1, modemst2

Those contain your imei and other phone stuff you don't wanna share.

What was your firmware version before UsU?
[AT&T LG G4] nagalun:
10o iirc before (and after UsU-ing). Nothing new but it could help someone to unbrick, maybe. :)

I asked [MENTION=5748995]efto[/MENTION] for his bl earlier in this thread since he seems to have (?) MM with arb 2. If he shared his files then it could really help, since that firmware seems very rare...

I also have a twrp backup of the 10o system/kernel, but I won't be able to upload it in some time
[AT&T LG G4] steadfasterX:
yea the MM one with ARB2 was only delivered as an OTA (LG proprietary dlpkgfile) only .. so THAT would be really a great help but yours as well ;)

[AT&T LG G4] nagalun:

I did flash. It is still not booting. AOSCP doesn't boot atall. LOS boots back to recovery. Please help.
[AT&T LG G4] smzubair:
So thankx for nagalun for sharing backups of before and after UsU.:laugh:

Steadfasterx pls advice what I do now? did I flash

"fastboot flash factory factory.bin

fastboot flash hyp hyp.bin

fastboot flash modem modem.bin

fastboot flash pmic pmic.bin

fastboot flash rpm rpm.bin

fastboot flash sbl1 sbl1.bin

fastboot flash sdi sdi.bin

fastboot flash sec sec.bin

fastboot flash tz tz.bin" these files in fastboot mode?

Please advise if yes and next process Thanks...:o
[AT&T LG G4] steadfasterX:
Exactly. Then just a flash a ROM in TWRP and see if it boots..

...and before doing all this take a basic SALT backup!!
[AT&T LG G4] smzubair:
Thankx for reply. I did it and flash CypherOS 4.2 and it Keeps booting, which never finish in this time. After 30 mins I pulled out Battery as Set going hot, and in some post u mentioned that if rom not boots in 15 mins, theres something wrong. One thing which is knocking on my mind that my set is compatible to h811, SALT shows. Do I search for h811 rom???? If yes then pls have any recommendations?
[AT&T LG G4] smzubair:
Thankx for sharing. I just need to confirm that your were on Marshmallow before UsU. (modem.bin)???
[AT&T LG G4] nagalun:
I was not in Marshmallow. If you read the filename, that backup contains the 10o firmware in both before and after UsU. Also, I believe you can't remove UsU by flashing my backup, else you will brick your bootloader because the secureboot has been triggered already.

What you could do to have a functional phone again is to flash the 10o android firmware, which does work after flashing UsU.

(You did make a TWRP/SALT backup of the original system, right?)
[AT&T LG G4] smzubair:
Can I flash this file in my case??? Im on h81010o too. If yes DL link is not working.:crying:

---------- Post added at 08:00 PM ---------- Previous post was at 07:55 PM ----------

Ahhhh I already mention that i've no backup and so no 10o android firmware. So I think i've no hopes for a working phone again.:eek:
[AT&T LG G4] nagalun:
I'll see if I remember to upload my android backup today when I get home then
[AT&T LG G4] smzubair:
Is this apply in my case

[AT&T LG G4] nagalun:
Yeah I'm uploading it... the file is 2GB and my internet is slow

Thankx a million

Sir thankx a million for this upload, i'll download it in evening and try it and let u know. But right now it seems u made my day. Thankx again

It is working again in Lollipop. Thankx

One thing that system partition is 4.5 gb and fat32 can't handle it. NTFS is ok but phone can't seek this partition so the last resort is ext2 or ext3 partition for sd card. This edit is also for those who needs to use this backup. Always make a backup, sometimes we can't find a kind person like "nagalun" who will here for our help.
[AT&T LG G4] Dr0ss3rv4r:

This tutorial serves for this model? Because I'd like to root my phone since I've seen that for this model you can not root through the blocked bootloader.

Hi Zubair,

I have H810. I was in 5.1 before USU. Please help me to Flash this rom. While i flash this rom, it reboots back to recovery. Please help.
[AT&T LG G4] smzubair:
Sorry for delay, I could'ny check my mails. From 5.1 to flash this rom is not possible, until we have MM Modem. Sadly no mm modem file for h810 is not available. so just you have to flash 5.1 from backup and use it. I've UsU, TWRP but still in 5.1:crying:. So just :laugh: and get back to LP(5.1).
[AT&T LG G4] jmorfeos:
Hi, Thanks [MENTION=5545101]steadfasterX[/MENTION] for this ROM and support.

I has MM ARB 2 in my G4 H810 and successfully Unlock it and install TWRP, and modem without problems. Make a SALT backup before UsU. But when installing ROM, I've made a TWRP bkp, but Android stuck in first screen . I come back to live with bkp. I've made a simple Wipe before, so I try a full wipe with DATA and retry ROM installation without GAPS. and it continues to stay in Android screen, and I've erased bkp with Wipe data.... :(

Any suggestion what should I do now?
[AT&T LG G4] nagalun:
Are you 100% sure you have MM with ARB2? Either way you could try to restore only the android system partition of the usu backup you did before using usu
[AT&T LG G4] jmorfeos:
Yes nagalun!! lookout, but isn't working well, maybe the problem come before I have the phone, I just make MM upgrade

Ok, then, should I try to restore with SALT my system partition?
[AT&T LG G4] nagalun:
You could try the debug rom before restoring the system partition, this one is supposed to be more crash proof: https://androidfilehost.com/?fid=673956719939819784

Also your firmware is rare so if you could upload your MM ARB 2 usu backup it would be a great thing, leave out the files mentioned here though :) : https://xdaforums.com/showpost.php?p=77002401&postcount=22
[AT&T LG G4] jmorfeos:
Ok, I will try it later at home.

Sure I can upload my backup but is before UsU, will be ok?
[AT&T LG G4] nagalun:
Yep!
[AT&T LG G4] jmorfeos:
Sorry for delay, I was travelling.

Here are misc, modemst1, modemst2 files from my MM ARB2 Salt Backup:

https://megaupload.nz/no/SALT_Backup_zip

I try to restore System backup but I just find to make a BCK but not to restore, can you help me?
[AT&T LG G4] nagalun:
!! Those were the files you didn't have to upload :(, everything else was needed (if your internet is slow you can leave out the system partition, if you want)

To flash the system I THINK you can do it through fastboot...

Boot into fastboot mode and try this from the PC (you must have system.bin in the current terminal's directory):

fastboot flash system system.bin
[AT&T LG G4] jmorfeos:
Sorry Nagalun, It was late at night and I understand it upside down :(. I will upload right files tonight and try fastboot command, thanks
[AT&T LG G4] jmorfeos:
Bad news!! I can't find system.bin in my Salt BKP , I don't know what happened. I was sure I had it...

It's my phone lost? or Can I install another ROM with TWRP?

Here are my backup files without system.bin

https://megaupload.nz/Z692w3l1b9/SALT_Backup_zip

Hope it helps, thanks again nagalun

Edit: I have found a guy that says problem are with modems for H810 here:

https://xdaforums.com/showpost.php?p=75736149&postcount=163

Maybe should I try your 10o modem?
[AT&T LG G4] nagalun:
Thanks for the backup!!!

Well... the first thing one should do is make a full TWRP backup after installing the recovery...

But, I think it's possible to recover your phone. You could either downgrade the phone to 5.1 (using my backup) or try to find a ROM that works on your phone (find a stock M ROM, AOSCP debug build, etc).

I think you should be able to flash my backup, but you might have to downgrade the bootloader, we're better off asking [MENTION=5545101]steadfasterX[/MENTION] about your current options to be safe

It would be neat to have both L and M boot loaders as flashable zips, now that we have both.

DON'T flash my L backup yet, wait for steadfasterX to take a look at this because I'm not 100% sure about downgrading safety

Yep, go ahead and try it, tell me how it goes. The rom in this thread doesn't require a modded modem, so flashing the original L modem is enough (no need to flash the UsU modem zip)
[AT&T LG G4] jmorfeos:
Hi Nagalun, I've tried this weekend, different modems and ROM with Kernels... I always have a bootloop or just stays booting.

Can you tell me which exacts steps you make to install a ROM to your H810 phone? Thanks for your help
[AT&T LG G4] nagalun:
I don't have any custom ROM installed... I've got stock ATT Android L, since I didn't have the MM ARB2 bootloader files, I was in L ARB2 and thus, couldn't flash any rom. This is why I asked you for the backup, but I didn't try it yet, flashing these files is dangerous and I'm still thinking if I want to take the risk or not.

Earlier in the thread I have a link to a TWRP backup of stock ATT android L, I don't think it will work in the MM bootloader, but you could try to restore it: #38

I really appreciate your hard work and commitment. Thank you for the tools you created so we can unlock our devices.

Today I succesfully unlocked my H810 using FWUL and all notice was perfect from the tool. then I did below things

1. Unlocked with Salt

2. Installed TWRP, booted to recovery and flashed the baseband package H810_UsU_baseband_flash-in-twrp.zip

3. While still in TWRP rebooted to recovery.

4. Rebooted to system

After couple of minutes I started installing the rom from this thread - aoscp_h810_usu-4.2-20180421-unofficial.zip

Here are the steps I took:

1. Rebooted in TWRP

2. Installed TWRP flashable N modem - G4_29a_N_modem_UsU.zip

3. Full wipe (FORMAT DATA)

4. Flashed aoscp_h810_usu-4.2-20180421-unofficial.zip

But when I restart my mobile. Its always shows some information with green screen, or sometime its shows Android logo with animation and nothing happened. Please help me to save my mobile from this issues.
[AT&T LG G4] steadfasterX:
Flash your original modem partition again and do not flash the baseband package. The baseband package is just needed if you want to flash a ROM which is *not* UsU compatible and this one is.

.
[AT&T LG G4] steadfasterX:
wow since decades you are the first one having a

MM

based ROM for the

H810

with ARB

= 2

.. thats incredible and I just had overseen it until today.

For reference I extracted the bootloader stack and uploaded it to my server:

[AT&T LG G4] jmorfeos:
Hi [MENTION=5545101]steadfasterX[/MENTION] , That's why I share it, some kind of thanks to your work. But my phone is still soft bricked, because I lost TWRP bkp and I can't find my system.bin from Salt BKP. I've tried different modem's and ROM's but it's still stays on boot screen. With Cypheros just spinning colored balls. Can you help me with some solution you think I should try? I had problems with my 20n stock ROM, maybe problem come from before I get phone. I have started with 10o tot, and flash it, then upgrade to 20n with OTA files in this Forum. but from beginning my modem was working very unstable and rebooting itself without visible cause.

Thanks again, :good:
[AT&T LG G4] smzubair:
Here are the steps I took:

1. Rebooted in Fastboot mode

2.Flashed MM boatlader stack (http://leech.binbash.it:8008/stock/LG/h810/20n/) as I was on LP

3. Rebooted in TWRP

4. Installed TWRP flashable N modem - G4_29a_N_modem_UsU.zip

5. Full wipe (FORMAT DATA)

6. Flashed aoscp_h810_usu-4.2-20180421-unofficial.zip

7. Flashed open_gapps-arm64-7.1-micro-20180614.zip

8.Flashed Magisk-v16.0.zip

But when I restart my mobile, took some time and booted successfully but Alas now SIM is not detected. IMEI is Unknown.

Again from step 3 I do it again but after step 5

I Flashed H810_UsU_baseband_flash-in-twrp.zip and then to step 8

Rebooted Succeesfully on Nougat but SIM not detected and IMEI is unknown. Whats wrong???
[AT&T LG G4] steadfasterX:
sure best for this is still IRC (see OP) but it requires a bit patience (due to maybe different timezones) and well Christmas is near so I will be not that much online then..

Do you have tried to

- flash the bootloader stack of 20n (including modem and

without

flashing baseband)

- flash this ROM

- and then trying to boot?

Use the modem partition of 20n and no baseband flashing when using an UsU compatible ROM.
